Primary spermatocyte to secondary spermatocyte � Meiosis - I converts primary spermatocyte into secondary spermatocyte. Prophase I � In the ovaries, main oocytes reach diplotene stage of prophase I (meiosis I), by the fifth month in utero and each stays at this stage until the interval earlier than ovulation (may be so lengthy as up to 50 years). Therefore, inside teratomas are present derivatives of all three germ layers and should embody skin, bone, teeth, gut tissue. Spermatogenesis Spermatogenesis is the process during which spermatozoa are produced from spermatogonial stem cells by means of mitosis and meiosis the primordial germ cells type spermatogonia, which yield primary spermatocytes by mitosis. Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce 4 spermatids. Only one pair of homologous chromosomes has been proven (red, maternal origin; blue, paternal origin). As a results of meiosis, every spermatid incorporates solely half of the genetic material current in the authentic major spermatocyte. Early spherical spermatids endure additional maturational occasion (spermiogenesis) to develop into spermatozoa. Initial phases of spermatogenesis takes place inside the testes (seminiferous tubules) and progress to the epididymis where the developing gametes mature, achieve progressive motility and are stored till ejaculation. Seminiferous tubules � Initial levels of spermatogenesis (meiosis) takes place within the seminiferous tubules of testes and progress to the epididymis the place the growing gametes mature, gain progressive motility and are stored till ejaculation. Type A (pale) cells, which are the spermatogonial stem cells that bear lively mitosis to produce Type B cells. Derived from secondary spermatocyte � Spermatid is the haploid male gamete that results from division of secondary spermatocytes. Secondary spermatocyte � Primary spermatocytes are diploid (2n) cells containing forty six chromosomes. Primary spermatocyte to secondary spermatocyte � Primary spermatocytes bear Meiosis I to give two secondary spermatocytes. Primary spermatocyte to secondary spermatocyte � Primary spermatocyte modifications to secondary spermatocyte throughout meiosis I. Oogenesis Primordial germ cells (46, 2N) derived from the epiblast cells, attain the endodermal wall of the yolk sac and differentiate into oogonia (46, 2N), which populate the ovary through mitotic division. After puberty, 5 to 15 primary oocytes start maturation with each ovarian cycle, but only one reaches full maturity to endure ovulation. Secondary oocyte is degenerated after 24 hours of ovulation, hence fertilization should happen within a number of hours, and not more than a day after ovulation. Approximate number of primary oocytes at fifth month of intrauterine life is 7 million, most of them get degenerated by birth and the count comes down to 600,000 to 2 million. The degeneration continues and at puberty, solely forty,000 are current, out of which 400-500 undergo ovulation in the feminine reproductive life. Twelve secondary oocytes are ovulated per 12 months, up to 480 over the complete reproductive life of the lady (40 years � 12 secondary oocytes per 12 months = 480). Only one pair of homologous chromosomes is shown (red, maternal origin; blue, paternal origin). Meiosis I is a reduction division and reduces the chromosome quantity to half in gamete. Primary oocyte completes meiosis I to type a secondary oocyte (23,2N) and a first polar physique (which later degenerates). Mitotic division � the overwhelming majority of oogonia continue to divide by mitosis, however some of them arrest their cell division in prophase of meiosis I and type major oocytes. Oogenesis � Polar our bodies are shaped because of meiosis in ovaries called as oogenesis. Primary oocyte arrested at prophase I � All primary oocytes are fashioned by month 5 of fetal life. First meiosis � Primary oocyte completes meiosis I to kind two daughter cells: the secondary oocyte (23, 2N) and the primary polar physique. Prophase � Prophase I (of meiosis I) is split into four phases: Leptotene, Zygotene, Pachytene and Diplotene.

The shorter the rectal stump, the extra doubtless that the surgeon may have issue identifying, mobilizing, and getting ready the rectal remnant for anastomosis. The maneuvers described previously (bimanual exam and use of transanal dilators) shall be useful on this circumstance. This easy transfer can prevent the large difficulties that ensue if the stapler is inadvertently pushed via the apex of the stump. Once the stapler has been efficiently placed, the pin is introduced out posterior to the transverse rectal staple line. After completion, all colorectal and coloanal anastomoses should be leak examined utilizing both povidone-iodine (Betadine) instilled into the rectum or air insufflation with the pelvis filled with saline answer. Liberal use of a diverting loop ileostomy for low anastomoses (<6 cm from the anal verge) or when building of the anastomosis has been tough is strongly suggested. Many of the technical elements described beforehand are important in reoperative pelvic pouch surgical procedure. Mobilization of the existing pouch should begin by establishing the posterior midline airplane between the pouch mesentery and the presacral fascia at the stage of the sacral promontory. Ureteric stents are necessary in these circumstances as a outcome of they can help facilitate identification of the ectopic ureters and help in the recognition of injuries. Lateral and anterior dissection are sometimes carried out flush with the serosal surface of the pouch to keep away from damage to pelvic sidewall buildings and the anterior parasympathetic nerves that management features of sexual function. In the rest, major pouch pathology, surgical trauma, and anatomical issues corresponding to abnormally small volume necessitated pouch excision and creation of a neo-ileal J pouch. This could be facilitated if the beforehand created diverting loop ileostomy was made thoughtfully and positioned roughly 20 cm proximal to the pouch, allowing the stapler to be launched via this enterotomy for creation of the 15 to 20 cm linear pouch staple line. Reach of the new J pouch to the anus is often not a difficulty, so long as the small bowel mesentery is completely mobilized to its origin and all interloop small bowel adhesions are divided. If reach is tough, creation of an S pouch will add a quantity of centimeters of length, though care should be taken to maintain the efferent limb lower than 2 cm in size to keep away from the potential of outlet obstruction. In our experience with redo ileal pouch surgery, creation of an S pouch somewhat than the standard J configuration is required in solely 10% of patients. Anal canal mucosectomy is then carried out from the perineal method starting just above the dentate line. A new diverting loop ileostomy is created, typically utilizing the present stoma aperture, and a presacral drain is placed. As stated previously, general outcomes following redo ileal pouch surgical procedure are excellent, with the vast majority of patients efficiently salvaged. Postoperative morbidity is common, however, with anastomotic leaks, pelvic sepsis, and bowel obstruction occurring in 8%, 10%, and 16% of sufferers, respectively. Bowel perform after redo pouch surgery is characterized by six daytime and two nighttime bowel actions per 24 hours with approximately 50% of sufferers admitting to seepage and pad usage. While lots of the principles described beforehand additionally apply to these patients, some further elements are frequent on this setting and require special consideration. In many cases, the primary operation that led to the anastomotic complication was related to rectal cancer, and the presence of recurrent disease ought to be excluded. Biopsies of the fibrotic perianastomotic tissues are obtained utilizing a core biopsy needle introduced by way of the anus. Endoscopy is carried out to assess the viability and distensibility of the neorectum, and digital exam defines the status of the anal canal and sphincters as nicely as the degree of fibrosis surrounding the neorectum and the capability of the pelvic outlet to accommodate a pulled-through segment of the colon and its mesocolon. A thorough preoperative medical evaluation is important in order that the risks of surgery may be thought-about against potential advantages. In cases the place operative risk is extremely high, colostomy creation alone may be the only choice. Rupert Turnbull and colleagues in the 1960s for the therapy of rectal cancer and Hirschprung illness,three and it was utilized by Dr. If a diverting loop ileostomy is created previous to redo ileal pouch anal anastomosis surgical procedure, it should be positioned roughly 20 cm proximal to the pouch.

Appropriate prophylactic parenteral antibiotics and subcutaneous heparin are administered, and sequential compression units are used for deep vein thrombosis prevention. The anus is sutured closed, if desired, following enema with a povidone-iodine solution to forestall contamination, and the lower stomach and perineum are prepped and draped. Alternatively, a hand port may be placed in a low-midline or by way of Pfannensteil position. It is necessary to observe that laparoscopic resection of rectal most cancers stays controversial. Although several collection have demonstrated the safety and feasibility of laparoscopic resection, as properly as many short-term advantages, the long-term oncologic equivalence to open surgery calls for further validation via well-designed randomized research. First, the stomach is initially explored for proof of metastasis, and any suspicious lesions might then be biopsied. The small bowel is then retracted superiorly and to the right and held in place with moist laparotomy pads. Alternatively, the patient is placed in a steep Trendelenburg position and rotated to the best to allow the small bowel to fall into the proper higher quadrant with the aid of gravity. Initial placement of the omentum over the top of the transverse colon and into the upper abdomen could help with small bowel area points, particularly in the morbidly overweight. Next, the redundant sigmoid colon is removed from the pelvis to ensure correct orientation. Using a lateral method, the sigmoid colon is grasped and mobilized medially by dividing the lateral attachments anchoring it to the left pelvic wall. The avascular airplane alongside the road of Toldt is divided, mobilizing the left colon. Bluntnosed scissors could also be positioned beneath the posterior parietal peritoneum and used to fastidiously separate the underlying gonadal vessels and ureter and shield them from harm. It is crucial to determine and shield the left ureter presently as a end result of it may course in shut proximity to the basis of the mesentery of the rectosigmoid, and may be simply damaged or transected throughout dissection. If preoperative ureteral stents have been positioned, the ureter can typically be simply and incessantly palpated to ensure it stays retracted to the left aspect of the pelvis and out of the dissection aircraft. Peristaltic waves can be seen if the ureter is pinched with forceps or laparoscopic atraumatic grasper. Identification of the sacral promontory is also a reproducible landmark that may allow entrance into the avascular presacral plane and assist the preliminary opening of the pelvic peritoneum. With the proximal colon retracted anteriorly and laterally, the dissection begins posterior to the superior rectal vessels and enters the presacral space with sharp division of the retrorectal fascia at about the stage of S2. It is important to visualize the sacral veins beneath parietal fascia and preserve a dissection aircraft simply anterior to these to keep away from troublesome bleeding. Extreme care must even be taken to forestall harm to the hypogastric nerves, which could be seen just under the iliac vessels and ureters bilaterally. Attention is then turned anteriorly, the place the peritoneal reflection within the cul-de-sac is incised behind the bladder in men or behind the uterus in women. The rectum must be carefully separated from the parietal fascia overlying the lateral pelvic wall structures. The autonomic nerve plexus can be seen coursing close to the rectum on the degree of the prostate or upper vagina. Damage on this area will end in a blended parasympathetic and sympathetic injury. The center rectal vessels could also be encountered bilaterally inside an space of fused mesorectal tissue. These vessels could additionally be ligated with using electrocautery, an power gadget, or require suture ligation. Once again, one must repeatedly be mindful of the course of the ureter all through the stomach portion of the procedure to forestall iatrogenic harm. We favor to use an power gadget, although a stapler with a vascular load or clamps and suture ligation can also be used. Conversely, some choose to divide the inferior mesenteric artery near its level of origin at the aorta. This will also help with gaining further size for circumstances in which the bowel must attain the anterior abdominal wall. Although this may be safely completed, one must be aware that this leaves the portion of the sigmoid that shall be used as a colostomy depending on collateral flow from the marginal artery of Drummond. High ligation of the inferior mesenteric artery also puts the preaortic sympathetic nerve plexus at risk for damage, which leads to retrograde ejaculation in the male.

In brief, the surgeon should adapt surgical principles to treating "the affected person [who has], typically, misplaced more blood than the system could conveniently spare. Except for those attributable to therapeutic or erotic misadventures through pure orifice, isolated blunt colon injuries rarely occur. In a survey of more than 200,000 blunt trauma patients, lower than a 3rd of the 1% of patients with a hollow viscus injury had colorectal involvement. The cecum, sigmoid, and transverse colon are the commonest sites of damage in blunt trauma, however mesenteric avulsion, full-thickness laceration, transection, and devascularization are seen mostly in the ascending and descending colon.

Those that accompany the motor nerves to voluntary muscle tissue are probably solely dilatory. Those reaching the viscera are involved with general vasoconstriction, bronchial and bronchiolar dilation, modification of glandular secretion, pupillary dilation, inhibition of gastrointestinal muscle contraction, and so forth. The preganglionic sympathetic fibres may relay in their corresponding (or larger and lower) ganglion and move to their corresponding spinal nerve for distribution or pass with out synapse to a peripheral (prevertebral) ganglion for relay. They are linked to the spinal nerves, limited to the spinal wire segments between T1 and L2.

The nephrogenic wire develops into three sets of nephric constructions (from cranial to caudal segments): the pronephros, mesonephros, and the metanephros. Pronephros � Develops by the differentiation of mesoderm inside the nephrogenic wire to type pronephric tubules and the pronephric duct. Metanephros � Develops from an outgrowth of the mesonephric duct (called the ureteric bud) and from a condensation of mesoderm inside the nephrogenic twine referred to as the metanephric mesoderm. The metanephros varieties the permanent kidney, having two portions: excretory & accumulating system. Excretory system is constituted by the nephrons, collecting system originates from the ureteric bud, an outgrowth of the mesonephric duct. Ureteric bud offers rise to the ureter, renal pelvis, major & minor calyces, and the whole collecting system. Connection between the collecting and excretory tubule methods is important for regular development. Early division of the ureteric bud might result in bifid or supernumerary kidneys with ectopic ureters. Kidneys develop in the pelvic region and later ascend into the abdomen (lumbar area), irregular ascent of the kidney, may end in anomalies like horseshoe kidney. Urorectal septum in cloaca region subdivides it into the urogenital sinus (anteriorly) and the rectum/anal canal (posteriorly). Urogenital sinus gives us a quantity of derivatives like urinary bladder, urethra in the in the feminine and male (prostatic & membranous portions). Table 20: the sequence of occasions of pronephros, mesonephros, and metanephros Nephrogenic cord/tissue Pronephros Mesonephros Location Cervical region Thoracolumbar region Segmentation Segmented Segmented Time look Beginning of the fourth week End of the fourth week of Functional standing Nonfunctional/ disappears Functional for a short interval then disappears, apart from its caudal excretory tubules Functional Duct Pronephric duct persists Mesonephric duct persists Metanephros Sacral area Nonsegmented Beginning of the third month Ureter Ascent of the Kidneys Fetal metanephros is situated at vertebral ranges S1-S2, whereas the definitive grownup kidney is located at vertebral degree T12-L3. The change in location results from a disproportionate growth of the embryo caudal to the metanephros. During the relative ascent, the kidneys rotate 90�, inflicting the hilum, which initially faces ventrally, to finally face medially. Vascular buds from the kidneys grow toward and invade the widespread iliac arteries, while in pelvis. Arteries shaped through the ascent may persist and are referred to as supernumerary arteries. Development of Collecting System Ureteric bud is an outgrowth of the mesonephric duct. It initially penetrates the metanephric mesoderm and then undergoes repeated branching to kind the ureters, renal pelvis, major calyces, minor calyces, and collecting ducts. Development of Nephron the inductive influence of the collecting ducts causes the metanephric mesoderm to differentiate into metanephric vesicles, which later give rise to primitive S-shaped renal tubules that are crucial to nephron formation. Note every nephron consists of the place where excretory unit (blue) establishes a communication with the accumulating system (yellow). The allantois turns into a fibrous wire known as the urachus (or median umbilical ligament) in the adult. The decrease ends of the mesonephric ducts become integrated into the posterior wall of the bladder to form the trigone of the bladder. Allantois is an endodermal diverticulum that extends from the ventral region of the urogenital sinus to the umbilicus. Later, its distal portion, known as the urachus, turns into a fibrous twine and varieties the median umbilical ligament. Absorption of 116 of ureters causes ureteric openings to shift laterally and upward. Embryology In each sexes, the mesonephric (or Wolffian) duct provides origin on each side to the ureteric bud, which forms the ureter, the pelvis of the ureter, the most important and minor calyces and the amassing tubules of the kidney. Its inferior end is absorbed into the creating bladder and forms the trigone and pat of the urethra. The terminal portion of mesodenphric duct (mesoderm) are absorbed into the posterior wall of urogenital sinus to kind trigone the terminal portion of mesonephric duct gets absorbed into the posterior wall of urinary bladder to kind the trigone (mesodermal). Note: Proximal a half of mesonephric duct (Wolffian duct) kind the conduit for sperm from the testes to the urethra and give rise to epididymis, ductus deferens, seminal vesicle, common ejaculatory duct. Table 22: Development of female and male urethra Urethra Female urethra Male urethra 1. Male urethra Clinical Correlations Renal agenesis occurs when the ureteric bud fails to develop, thereby eliminating the induction of metanephric vesicles and nephron formation.

Angiographic embolization is safe and efficient remedy in blunt abdominal strong organ damage in youngsters. The failure rate of nonoperative administration in youngsters with splenic or liver harm with distinction blush on computed tomography: a systematic evaluate. Computed tomography grade of splenic damage is predictive of the time required for radiographic therapeutic. Crucial elements thought of embody the nature of the underlying disease, the severity of symptoms, alternative therapeutic choices, the operative risk, and the success fee of splenectomy. During the previous decade, the underlying illnesses have turn into higher understood; extra and efficient medical therapies have turn into obtainable, specifically immunomodulatory/immunosuppressive regimens; laparoscopic techniques have expanded and decreased operative dangers; and prophylaxis has minimized the danger of postsplenectomy infections. These advances have challenged some of the conventional concepts relating to splenectomy. This article goals to summarize the present indications and modern outcomes of splenectomy for nontraumatic circumstances encountered by surgeons in consultation. These situations mainly include hematologic issues but in addition splenic mass lesions, splenic vascular illness, iatrogenic injuries, and other uncommon illnesses. Spontaneous inner bleeding might happen with platelet counts of 10 � 109 to 20 � 109/L. Response of thrombocytopenia to therapy has been variably outlined in earlier studies. Relapse occurs when thrombocytopenia recurs after attaining a standard platelet count. Affected sufferers may be asymptomatic or could current with petechiae, ecchymosis, epistaxis, gastrointestinal bleeding, or menorrhagia. Splenic macrophages clear platelets coated with immunoglobulin G (IgG) autoantibodies in an accelerated style. The take a look at for antiplatelet antibodies has a sensitivity of solely 49% to 66% and a specificity of 78% to 92%. A search for a secondary cause for thrombocytopenia ought to be prompted by a history of drug or toxin exposure, latest viral infections, splenomegaly on physical examination, an abnormal peripheral smear, or a hypoplastic bone marrow. Although a peripheral blood smear has been required as a diagnostic check, bone marrow aspiration is taken into account for patients older than age 60 years with atypical shows and in whom different disorders are suspected and splenectomy is contemplated. In approximately 90% of the sufferers the illness manifests as acute thrombocytopenia, associated with a sudden onset of petechiae occurring 4 to 8 weeks after the prodrome of viral illness, allergies, or immunizations. It maintains the circulating blood parts by filtering and eradicating damaged or senescent cells. As the largest combination of lymphoid tissue in the reticuloendothelial system, the spleen capabilities in both antibody manufacturing and phagocytosis. Accordingly, cytopenia and splenomegaly are two widespread manifestations of hematologic issues involving the spleen. Cytopenia is related to hypersplenism, the excessive destruction of one or more blood parts. Splenomegaly, defined as splenic weight of greater than one hundred seventy five g (normal, ninety to a hundred and fifty g), can turn out to be huge (>1000 to 15,000 g). When the spleen is the sole site of the illness or a serious contributor to the underlying pathophysiology, splenectomy is carried out with curative intent. In basic, splenectomy for hematologic illness could be diagnostic, therapeutic, healing, or palliative and is performed for particular medical indications rather than for particular diagnoses. Patients with platelet counts of fifty � 109/L or higher are usually asymptomatic and are discovered by the way. Regardless of disorder, splenectomy may be indicated for diagnosis, symptomatic splenomegaly, or clinically significant cytopenias. This article assesses the function of splenectomy broadly for nontraumatic conditions and supplies an overview of the operative approaches and administration of the postsplenectomy state. Typical management consists of remark and avoidance of platelet-inhibiting medications and of activities predisposing to trauma. Although the disease course is normally benign, these with extreme or refractory thrombocytopenia face four instances the danger of mortality than the final population. Recent research in patients present process therapy with dexamethasone regimens have demonstrated up to 86% response fee, with 50% to 74% sustained response. The common relapse price after splenectomy is 15% (range, 0% to 51%), most occurring within the first postoperative yr. One single-center experience of a hundred and forty adults revealed an general complete platelet response rate of 78% initially and 74% after 1 12 months.

Several studies have demonstrated improved detection of dysplasia utilizing chromoendoscopy (compared with normal white gentle colonoscopy) in patients with long-standing ulcerative colitis. Other gadgets for improving adenoma detection embrace cap-fitting, Third Eye Retroscope (Avantis Medical Systems, Sunnyvale, California), and Full Spectrum Endoscopy (Fuse) (Endochoice, Atlanta, Georgia). Cap-fitted colonoscopy includes putting a plastic cap on the top of the colonoscope. Several research, together with a randomized tandem examination study, have proven a rise in adenoma detection with cap becoming. It is positioned by way of the biopsy channel and due to this fact has to be removed to remove any polyps recognized. The Fuse colonoscope has a 330-degree area of view in contrast with 170 levels for a standard colonoscope. Kudo described pit patterns in polyps viewed underneath colonoscopic magnification (Table one hundred forty five. The use of coagulation mode decreases the likelihood of quick bleeding from the stalk. Care must be taken to maintain the tip of the snare off of the adjoining colon wall when making use of the coagulation present to keep away from unintended thermal damage. Polypectomy for sessile polyps is dependent upon several features, together with dimension and placement. Polyps less than 5 mm are eliminated by chilly biopsy forceps, which can be found in standard and jumbo sizes. The mucosa must be examined for full removal of neoplasia, and extra passes may be required. After greedy the polyp, coagulation is utilized to the tissue until blanching happens and a firm pull utilized to the catheter. The amount of coagulation is imprecise, and this technique is being used much less commonly due to the chance of perforation and delayed postpolypectomy bleeding. No data exist demonstrating a single electrosurgical mode or generator as superior over others in performing sizzling snare polypectomy, however the tradeoff is a higher rate of acute bleeding with cutting current and a higher fee of delayed bleeding and perforation with coagulation. Saline is injected into the submucosal aircraft previous to putting the snare across the polyp. The injection ought to begin on the proximal aspect of the lesion to push the polyp towards the scope. As the snare is tightened, the tip of the catheter is moved toward the distal extent of the polyp. Coordinated closure of the snare by the assistant simultaneous with software of present completes the transection. In a systematic evaluation of 12 research totaling 57,742 patients who underwent average-risk screening, the overall opposed fee was 2. However, 85% of the serious complications have been reported in sufferers present process colonoscopy with polypectomy, producing a reported complication rate ranging from 0. Prompt identification and appropriate management minimize the morbidity and mortality of those issues. It is often the end result of forceful passage through a loop that splits the bowel on the intestinal narrowing (most commonly in the sigmoid colon). These constricted areas are sometimes a results of diverticular illness or adhesions from previous pelvic surgeries. It is uncommon for the tip of the scope to perforate the bowel besides when unhealthy tissue is current, corresponding to ischemia, ulcer, or irritation. Urgent radiography may affirm the diagnosis by the presence of free intraperitoneal air.

Blind insertion of the ultrasound probe is feasible, but it might be troublesome to advance the probe proximal to the lesion and may trigger the affected person important discomfort. Newer probes have a crystal that moves within a portion of the distal shaft of the probe. A long balloon is fitted over the probe, which is handed through a specialised proctoscope. The proctoscope is partially withdrawn, exposing the world on the probe where the crystal strikes and locked into place. The balloon is crammed with degassed liquid, distending it along the entire size of the probe. The balloon covering the probe is massive and requires greater than 200 mL to distend it and rectal wall adequately. The operator moves the crystal up and down the shaft by urgent controls on the probe. The crystal travels roughly 7 cm, so it might be necessary to pull the proctoscope and probe lower and carry out a second pass to utterly evaluate the length of the rectum. Flexible endoscopes with mounted ultrasound ideas can be found and allow analysis of lesions proximal to 15 cm. The fixed ultrasound probes have interchangeable crystals with a quantity of transducer capabilities. The movable probes have multifrequency transducers, which allow the investigator to change frequency to improve visualization without having to substitute the crystal on the finish of the probe. Older machines are two dimensional, which permits for video recording and photodocumentation of static photographs. Tumor quantity may be measured and the relationship between the tumor and contiguous buildings better understood. Interface balloon and mucosae Inner white line P identify perirectal lymph nodes and the tumor depth within the rectal wall. The picture could be frozen to get still pictures of consultant levels for chart documentation. The movable crystal permits the probe to keep stationary above the tumor whereas the crystal advances by way of the tumor-generating images. Tissues that have a better fluid content material seem black whereas interfaces and tissues with much less fluid density seem white. Smooth muscle with a excessive fluid content material seems black and skeletal muscle appears white. The fluid-filled balloon is the central massive black picture surrounding the transducer. The first hyperechoic white line is the interface between the balloon and the mucosa. The subsequent hypoechoic black line is the muscularis propria, and the outer hyperechoic white line is the interface between the muscularis propria and the perirectal fat. Blood vessels may be seen within the surrounding tissues and seem as hypoechoic round constructions, which may elongate as the probe is withdrawn. Hypoechoic strains (black) represent the internal muscularis mucosae and the outer muscularis propria. Hyperechoic traces (white) characterize the interfaces between the balloon (inner), submucosa (middle), and perirectal fats (outer). The seminal vesicles are seen anteriorly as bilateral hypoechoic (black) structures. Tubulovillous adenomas are benign uT0 lesions that could be seen increasing the mucosal layer (the first black line). The middle white line is thickened and irregular however not disrupted, indicating invasion into but not by way of the submucosa. The outer white line is unbroken, indicating that the tumor is confined to the rectal wall. The outer white line is irregular and interrupted, indicating tumor invasion into the perirectal fats. Metastatic lymph nodes that have been replaced by tumor appear spherical and hypoechoic and have distinct borders. Hypoechoic lesions bigger than 5 mm may be metastatic in up to 70%,23 whereas these measuring 3 to 5 mm may be metastatic in as a lot as 50%. The ultrasound nodal stage was 80% correct for pT3 lesions and less than 50% correct for pT1 lesions.
