A Case of Rectal Cap Polyposis Cured by Segmental Resection / 대한소화기내시경학회지

Cap polyposis is a rare condition, which is characterized by inflammatory polyp located mainly from the rectum to the sigmoid colon with a "cap"-coverage of granulation tissue. A 60-year-old woman with tenesmus, constipation, and abdominal pain visited our hospital. Colonoscopy showed variable sized multiple polypoid lesions limited in high rectum, mainly 10 cm distance from anal verge. No other abnormalities of colonic mucosa were seen beyond this area. Medical treatments including stool softner and oral steroid had a little symptomatic improvement. Because symptoms had been frequently recurred after withdrawal of these medications, surgical resection was intended for diagnosis and curative treatment. Resected specimen showed multiple inflammatory polyps with granulation cap. After the resection, the patient has been good at daily activity without evidence of symptomatic or endoscopic aggravation.

Effectiveness of Walking-exercise on Bowel Preparation for Colonoscopy / 대한소화기내시경학회지

BACKGROUND/AIMS: This prospective study was conducted to assess the effect of walking-exercise on the bowel cleansing before colonoscopy and to define subgroup of patients to whom walking-exercise was beneficial. METHODS: Before taking 2.5 L of polyethylene glycol, 393 out-patients were randomized into two groups (G1; walking-exercise, G2; non-exercise) and the amount of walking-exercise was estimated by the step counter. A single colonoscopist performed the procedure with a single-blinded manner and estimated the bowel cleansing. RESULTS: A total of 366 patients were included by per protocol analysis. The number of step count was significantly different between two groups (p<0.000). However, the groups were similar in other data collected. The degree of bowel cleansing between two groups was significantly different (p<0.01). Age, history of abdominal surgery, constipation, obesity and walking- exercise were related to the degree of bowel cleansing. Interestingly, walking-exercise was especially beneficial to patients with age less than 65 years, without history of abdominal surgery, and non-obesity. Multivariate analysis demonstrated that absence of constipation (OR=4.74), walking- exercise (OR=2.04), and younger age (OR=1.97) were independent factors associated with better bowel cleansing. Most of walking patients (97.4%) answered that walking-exercise is more comfortable than taking the solution. CONCLUSIONS: The walking-exercise was of an additional benefit to improve colonoscopic bowel cleansing without significant patients discomfort.

A Case of Calcitonin Secreting Pheochromocytoma / 대한내분비학회지

Pheochromocytoma is a catecholamine producing turnor and raise with less than 0.1% of hypertensive patients. It is developed, most commonly, in sporadic pheochromocytoma or multiple endocrine neoplasia type 2. Therefore, when hypercalcitoninemia is found in a patient with pheochromocytoma, the possibility of multiple endocrine neoplasia type 2 or the ectopic secretion of calcitonin must be considered. Recently we experienced a 45 year old male patient with sporadic pheochrornocytoma. He also had hypercalcitoninemia and normocalcemia. After the removal of pheochromocytoma, serum calcitnnin level returned to normal. Secretion of calcitonin was confirmed by immunohisto- chemical stain.
