In acute pancreatitis, colonic complications such as mechanical obstruction, ischemic necrosis, hemorrhage, and fistula are rare but their outcomes are fatal. It is known that colonic obstruction in acute pancreatits is more likely found in splenic flexure and transverse colon caused by severe inflammation of body and tail of pancreas leading to pressure necrosis. A 43-year-old man presented with abdominal distension lasting for 2 weeks. The patient had been admitted to our institution 6 weeks prior to the current admission, and the abdominal CT scan performed during the first admission revealed the pancreatic enlargement with peri-pancreatic fatty infiltration and fluid collection. At that time he was diagnosed as acute pancreatitis. The conservative management resulted in clinical improvent so that the patient was discharged. Upon the second admission, abdominal CT scan revealed multiple pseudocysts in the tail portion of pancreas with concominant wall thickening and narrowing of the proximal descending colon, and a dilatation of the bowel proximal to the splenic flexure. An obstruction of the descending colon as a complication of acute pancreatitis was suspected and the patient underwent left hemicolectomy. Abdominal distension was relieved after the operation and he was discharged on the 15th hospital days.

Most common cause of brisk hematochezia is diverticular bleeding in Western countries. It occurs in 15% of patients with diverticulosis and one-third of them appear to be massive. Most of diverticulosis in Western countries occur in the left colon but the right colon is more common in Korea. Especially, the reports of diverticular bleeding on left colon are rare in Korea. We report a case presenting with multiple diverticuli complicated by recurrent massive bleeding restricted to the left colon. 75-year-old female was admitted due to hematochezia and dizziness. On past history, two years and two weeks ago respectively, she was treated of diverticular bleeding with and without diverticulitis. Hemoglobin level was 9.8 g/dL. On Colonoscopy, numerous diverticuli were seen at sigmoid colon upto splenic flexure which showed fresh blood clots in the lumen. We diagnosed her as recurrent massive diverticular bleeding on the sigmoid colon. She received elective laparoscopic left hemicolectomy.

Toothbrush swallowing is a rare event. Because no cases of spontaneous passage have been reported, prompt removal is recommended to prevent the development of complications. Most swallowed toothbrushes have been found in the esophagus or the stomach of affected patients, and there has been no previously reported case of a toothbrush in the colon. Here, we report a case of a swallowed toothbrush found in the ascending colon that caused a fistula between the right colon and the liver, with a complicating small hepatic abscess. This patient was successfully managed using exploratory laparotomy. To our knowledge, this is the first documented case of a swallowed toothbrush found in the colon.

Several forms of colonic complications are rarely observed during the clinical course of acute pancreatitis, and potentially fatal in some cases. Colonic lesions associated with acute pancreatitis can be divided into several groups from a pathogenic point of view. Possible pathogenesis includes 1) spread of pancreatic enzymes through the retroperitoneum to mesocolon, causing pericolitis, 2) external inflammatory compression by mesocolic mass secondary to necrosis of fatty tissue, and 3) hypotension due to shock, and thrombosis of mesenteric arteries. These might lead to colonic infarction, fistula formation, perforation, and obstruction during follow-up. We report two cases of colonic obstruction following acute pancreatitis with possible different mechanisms and review Korean cases. One patient developed colonic obstruction due to severe necrotizing pancreatitis, possibly as a result of pericolitis, and the other developed stenosis as a result of ischemic colitis induced by acute pancreatitis.

BACKGROUND/AIMS: Colonoscopic polypectomy is a valuable procedure for preventing colorectal cancer, but is not without complications. Delayed bleeding after colonoscopic polypectomy is a rare, but serious complication. The aim of this study was to identify risk factors of delayed bleeding after colonoscopic polypectomy. METHODS: A retrospective case-control study was conducted in a single university hospital. Forty cases and 120 controls were included. Data collected included comorbidity, use of antiplatelet agents, size and number of resected polyps, histology and gross morphology of resected polyps, endoscopist's experience, resection method, use of sedation, and use of prophylactic hemostasis. RESULTS: In univariate analysis, size, histology and number of resected polyps, endoscopist's experience, resection method and use of prophylactic hemostasis were significant risk factors for delayed bleeding after colonoscopic polypectomy. In multivariate analysis, risk of delayed bleeding increased by 11.6% for every 1 mm increase in resected polyp diameter (OR, 1.116; 95% CI 1.041-1.198; p=0.002). Number of resected polyps (OR, 1.364; 95% CI, 1.113-1.671; p=0.003) and endoscopist's experience (OR, 6.301; 95% CI, 2.022-19.637; p=0.002) were significant risk factors for delayed bleeding after colonoscopic polypectomy. CONCLUSIONS: Size and numbers of resected polyps, and endoscopist's experience were independent risk factors for delayed bleeding after colonoscopic polypectomy. More caution would be necessary when removing polyps with these factors.

BACKGROUND/AIMS: A stercoral perforation of the colon (SPC) is a rare, life-threatening disease. The aim of this study was to represent the definition of SPC and help the diagnosis and treatment of this condition. METHODS: We reviewed 92 medical records of patients who underwent operation due to colonic perforation from January 2000 to February 2009 retrospectively. Maurer's diagnostic criteria were used for the diagnosis of SPC. RESULTS: Eight patients (8.7%) were diagnosed as SPC. The age of the patients ranged from 59 to 85 years old. All of the patients were female and had a history of long-standing constipation. Only two patients (25%) were diagnosed as SPC preoperatively. The site of perforation of all patients was sigmoid colon. The methods of operation were Hartmann's procedure (7 cases), and primary repair with sigmoid loop colostomy (1 case). There were one recurrence and two deaths (25%) due to sepsis and multiple organ failure. CONCLUSIONS: SPC should be considered in chronically constipated, and bedridden patients who present with acute abdomen. Hartmann's procedure is the treatment of choice in most situations. Mortality is high but can be minimized with early definitive surgery.
