BACKGROUND: To establish the incidence of unsuspected malignancy in lesions excised through transanal endoscopic microsurgery (TEM) and examine the justification for full-thickness excision of all lesions thought to be benign pre-operatively. METHODS: Demographic, operative and pathology data of all patients undergoing TEM at a single institution were collected in a prospectively maintained database. Follow-up data were collected with a focus on polyp recurrence rates and outcome in patients found to harbour malignancy...

Colonic polyps are usually asymptomatic, and are commonly detected during screening colonoscopy. Severe hypokalemia secondary to secretory diarrhea is a rare presentation of rectal polyps. We present a 70 years old female with hypokalemia and acute kidney injury secondary to secretory diarhea due to moderately differentiated adenocarcinoma of rectum, all of which is syndromically sometimes referred to as McKittrick and Wheelock syndrome. The case is presented because McKittrick-Wheelock syndrome is still more uncommon with malignancy...

CONTEXT: Recurrent somatic mutations in KCNJ5, CACNA1D, ATP1A1 and ATP2B3 have been identified in aldosterone producing adenomas (APA). The question as to whether they are responsible for both nodulation and aldosterone production is not solved. CASE DESCRIPTION: We describe the case of a young patient who was diagnosed with severe arterial hypertension due to primary aldosteronism at age 26, followed by hemorrhagic stroke four years later. Abdominal computed tomography showed bilateral macronodular adrenal hyperplasia...

Russell body gastroenteritis has been reported as a reactive inflammatory process in most cases and many of the reports were from the upper gastrointestinal tract, especially the stomach, which may be associated with Helicobacter pylori infection and rarely associated with gastric carcinoma. Russell body containing Mott cells have been rarely seen in Barrett's esophagus and duodenum, and only 2 cases have been reported in colon, including a transplant patient with diarrhea and a rectal tubulovillous adenoma...

BACKGROUND: We identify the features of multiple primary colorectal cancer (MPCC), synchronous colorectal cancer (SCRC) and metachronous colorectal cancer (MCRC), and distinguish between the cases that require a more extensive surgery and those where the parameters of SCRC might be important to prevent the development of MCRC. METHODS: We gathered up consecutive individuals with MPCC, 50 for each category, and 100 consecutive individuals diagnosed with 'single' colorectal cancer...

Hamartomatous polyps (HPs) in the gastrointestinal (GI) tract are rare compared to other types of GI polyps, yet they are the most common type of polyp in children. The symptoms are usually rectal bleeding, abdominal pain, obstipation, anaemia, and/or small bowel obstruction. The polyps are typically removed concurrently with endoscopy when located in the colon, rectum, or stomach, whereas polyps in the small bowel are removed during push-enteroscopy, device-assisted enteroscopy, or by surgery. HPs can be classified as juvenile polyps or Peutz-Jeghers polyps based on their histopathological appearance...

Colonic lipoma is a rare non-epithelial mesenchymal tumour which is the second most common benign tumour of the colon excluding hyper-plastic polyps. It is often small and asymptomatic but may become symptomatic and mimic malignant lesions as the size increases. This is a case report of a 68 year-old female patient who presented with lower abdominal pain, constipation and rectal bleeding of one year duration. Colonoscopy revealed a sessile tumour 40 cm from the anal verge with an inconclusive histology. After incising and removing the lipoma, the redundant mucosal fold was then resected...

Colitis cystic profunda is a rare entity benign condition of the colon and rectum that can mimic suspicious polyps or malignancy. The commonest sites of affectation are the rectum and the sigmoid colon but it can be unusually widely distributed in the colon. The aetiology of this condition is not fully elucidated and confident diagnosis can only be made on histological features. We hereby describe a patient who presented with significant rectal symptoms and an unexpected finding of a submucosal mucous cyst mimicking a suspicious rectal polyp and highlighted its significance and the review of the literature...

A 49-year-old Brazilian male presented to the emergency department with a five-day history of abdominal pain, dark stools, and syncope. Physical examination did not reveal any melena on digital rectal examination and there were no stigmata of chronic liver disease. Laboratory results showed hemoglobin of 47 g/L, MCV of 80 fL, and ferritin of 6 ng/mL. Liver enzymes and liver function tests were normal. Abdominal ultrasound showed a cirrhotic liver with splenomegaly and varices suggestive of portal hypertension...

Peutz-Jeghers Syndrome (PJS) is an autosomal dominant intestinal polyposis syndrome characterised by the presence of hamartomatous polyps and mucocutaneous pigmentation. Prolapse of the polyps through the anus is an infrequent manifestation in children with PJS, and this complication is extremely rare in adult patients. We report the case of a 30-year-old man recently diagnosed with PJS who was seen at the emergency department because of the abrupt onset of severe anal pain with a foreign body sensation in the anal canal and rectal bleeding...

RATIONALE, AIMS AND OBJECTIVES: Variation in the workup of rectal bleeding may result in guideline-discordant care and delayed diagnosis of colorectal cancer. Accordingly, we undertook this study to characterize primary care clinicians' initial rectal bleeding evaluation. METHODS: We studied 438 patients at 10 adult primary care practices affiliated with three Boston, Massachusetts, academic medical centres and a multispecialty group practice, performing medical record reviews of subjects with visit codes for rectal bleeding, haemorrhoids or bloody stool...

Colorectal polyps are frequent in the general population. The diagnostic is made by endoscopy. Polyp's characteristics determine the technic to be used to remove them. Transanal endoscopic microsurgery offers an alternative to radical surgery for large rectal polyps or rectal tumors with low risk of node invasion. One peace resection is necessary to evaluate the resection margins. Lymphatic invasion, ≥ 1 mm submucosae invasion, tumor budding and poorly differentiated tumor are the four main risk factors for node invasion...

Appendiceal adenocarcinoma typically presents as an incidentally noted appendiceal mass, or with symptoms of right lower quadrant pain that can mimic appendicitis, but local involvement of adjacent organs is uncommon, particularly as the presenting sign. We report on a case of a primary appendiceal cancer initially diagnosed as a rectal polyp based on its appearance in the rectal lumen. The management of the patient was in keeping with standard practice for a rectal polyp, and the diagnosis of appendiceal adenocarcinoma was made intraoperatively...

OBJECTIVES: With advances in diagnostic endoscopy, the detection of rectal neuroendocrine tumors (NETs) has increased. However, clinical outcomes, especially after endoscopic treatment, are still unclear. The aim of this study was to determine the long-term clinical outcomes of endoscopically resected rectal NETs according to the pathologic status after initial resection. METHODS: In this large, multicenter, retrospective cohort study, we analyzed the medical records of patients who underwent endoscopic resection of rectal NETs and were followed for ≥24 months at 16 university hospitals...

Almost all large and complex colorectal polyps can now be resected endoscopically. Piecemeal endoscopic mucosal resection (PEMR) is an established technique with fairly low complication risk and good short-term and medium-term outcomes. Several modifications to the basic injection and snare technique have been developed contributing to safer and more complete resections. Delayed bleeding requiring reintervention is the most troublesome complication in 2-7% of patients, particularly in those with comorbidities and large, right-sided polyps...

A 42-year-old woman presented with abdominal pain. On the basis of CT results, we diagnosed her condition as bowel obstruction caused by advanced transverse colon cancer. Colonoscopy findings showed three lesions: (i) an advanced tumor in the transverse colon; (ii) a laterally spreading descending colon tumor; and (iii) a rectal polyp. The tumors and the polyp were all pathologically diagnosed as adenocarcinoma. After inserting a self-expanding metallic stent into the main tumor of the transverse colon to decompress the bowel, we performed endoscopic submucosal dissection of the laterally spreading descending colon tumor...

BACKGROUND: Enteric-type glandular lesions are extremely rare in the vagina. Their histological origin remains a matter of speculation at present. METHOD: We review two rectal mucosal prolapse-like polyps and one intestinal-type adenosis in the vagina. RESULTS: Case 1, a 64-year-old woman, presented with a vaginal polypoid lesion with a size of 4 × 3 × 3 cm. Case 2, an 8-year-old girl, had a 1.5 × 1.5 × 0.8-cm pedunculated polyp in the vaginal navicular fossa and a clinically suspected rectovaginal fistula...

Human enteric neural stem cells (hENSCs) proliferate and differentiate into neurons and glial cells in response to a complex network of neurotrophic factors to form the enteric nervous system. The primary aim of this study was to determine the effect of basic fibroblast growth factor (bFGF) and epidermal growth factor (EGF) on in-vitro expansion and differentiation of postnatal hENSCs-containing enteric neurosphere cells. Enteric neurosphere cells were isolated from rectal polyp specimens of 75 children (age, 1-13 years) and conditioned with bFGF, EGF, bFGF+EGF, or plain culture media...
