A 64-year-old woman underwent polypectomy for a rectal polyp(Isp). Pathological findings were invasion of the submucosa( 3,500 mm diameter), and she underwent anterior resection for rectal cancer(RS, pT1b, pN0, cM0, Stage I )without adjuvant chemotherapy. Lung masses were found in her right(8mm)and left lung(7mm). The tumors enlarged during the 4 month follow-up period. We decided to perform left partial pneumonectomy. The tumor was diagnosed as a lung metastasis from colon cancer by pathology. Because the right tumor was located towards the center, performing right pneumonectomy would have been quite invasive and we feared occult metastases...

PURPOSE: The cumulative incidence of post-colonoscopy colorectal cancer remains unclear. Our aims were to estimate the incidence of and identify risk factors associated with post-colonoscopy colorectal cancer. METHODS: We conducted a retrospective cohort study using the colonoscopy database of the Department of Gastroenterology, the University of Tokyo Hospital Records from1995-2012. A cohort of 2544 patients, who received multiple colonoscopies without colorectal cancer findings at first colonoscopy, was selected...

An 8-yr-old nulliparous, female rock hyrax ( Procavia capensis ) had intermittent mucoid to bloody discharge late winter-early spring for two consecutive years. Fragments of necrotic tissue, suspected to be vaginal or rectal in origin, were passed on two occasions. Physical examination, radiographs, and ultrasound did not identify the source of the tissue. Exploratory laparotomy and ovariohysterectomy were performed. On histopathology, a diagnosis of adenomyosis with a uterine polyp was made. Postsurgical complications included incisional infection and renal compromise that were medically managed and resolved...

PURPOSE: Helicobacter pylori infection is considered to have a positive association with colorectal neoplasms. In this study, we evaluated the association between H. pylori infection and colorectal adenomas, based on the characteristics of these adenomas in Korea, where the prevalence of H. pylori infection is high and the incidence of colorectal cancer continues to increase. METHODS: The study cohort consisted of 4,466 subjects who underwent colonoscopy and esophagogastroduodenoscopy during screening (1,245 colorectal adenomas vs...

BACKGROUND: The incidence of malignant synchronous colorectal tumors (SCRT) is between 2% and 5%, and the association of synchronous adenomatous polyps in colon cancer has been reported to be 15%-50%. Surgical resection is the primary treatment option for SCRT not amendable to endoscopic resection. Lesions in adjacent segments are usually treated with more extensive resection; however, there is still some controversy on how to best treat synchronous lesions in separate segments, especially when the rectum is involved...

Anorectal malignant melanoma is a very rare but lethal disease. Patients with anorectal malignant melanoma commonly complain for changes in bowel habits and rectal bleeding. Therefore, anorectal malignant melanoma is often misdiagnosed as hemorrhoids, polyp or rectal cancer. Surgery is the mainstay of treatment for patients with anorectal malignant melanoma. However, whether abdominoperineal resection or wide local excision is the most appropriate surgical approach is still a controversial issue. Recently, with the great development of laparoscopic techniques, more and more operations can be performed by laparoscopic techniques...

A polyp is defined as a mass of the mucosal surface that protrudes into the lumen of the gastrointestinal tract. Neoplastic epithelial polyps are classified histologically as either benign adenoma or malignant carcinoma. The colonic polyps that most commonly present in children occur sporadically and individually and are of the juvenile type; they are most frequently associated with painless rectal hemorrhage (which is the most common symptom). Adenomatous polyps are similar to other nontumoral polyps, and it is very rare for children to have symptoms other than rectal bleeding...

BACKGROUND: In a large number of patients with multiple gastrointestinal adenomatous polyps, no causal germline mutation can be found. Non-genetic factors may contribute to the development of adenomatous polyps in these unexplained polyposis patients. In the development of gastrointestinal cancer, prior exposure to abdominal radiotherapy has been identified as such a factor, as it increases the gastrointestinal cancer risk in cancer survivors. A relationship of radiotherapy with intestinal polyposis, however, has not yet been described...

Inflammatory polyps are relatively common in patients with inflammatory bowel disease. The term giant inflammatory polyposis is used to describe inflammatory polyps greater than 1.5 cm in any dimension. Their clinical presentation can be varied, ranging from asymptomatic, with incidental detection on radiological or endoscopic testing, to symptomatic, with rectal bleeding and colonic obstruction. Although giant inflammatory polyposis is a rare finding, it is of clinical importance, since it is easily mistaken for colon cancer, with patients sometimes undergoing radical surgeries...

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...
