A Case of Postpolypectomy Coagulation Syndrome Had a Hemicolectomy / 대한소화기내시경학회지

Colonoscopy is commonly used as a screening tool for colorectal polyps and cancer. It also offers a chance to remove polyps via the polypectomy technique. Colonoscopic polypectomy is a relatively safe procedure, yet there is the possibility of serious complications such as perforation and bleeding. Postpolypectomy coagulation syndrome presents with pain, fever, an elevated white blood cell count and signs of peritoneal irritation, and usually within 12 hours of the procedure. No free air is seen on plain films or a CT scan, which is different from frank bowel perforation. The management of postpolypectomy coagulation syndrome includes fasting, antibiotics and intravenous hydration. We report here on a case of a 53-year-old woman who underwent right hemicolectomy because she presented with fever, signs of peritoneal irritation and shock after colonoscopic polypectomy. The final diagnosis was postpolypectomy coagulation syndrome as there was no perforation in the resected specimen.

Complication of Colonoscopic Polypectomy / 대한소화기내시경학회지

BACKGROUND/AIMS: Colonic adenomatous polyp is known as a premalignant lesion. Colonoscopic polypectomy, using for its removal and prevention of primary colon cancer has been considered as a effective and safe method. This study was conducted to assess its complication and safety of colonoscopic polypectomy. METHODS: One thousand two hundred ninety three polypectomy were done using colonoscopic hot biopsy, snare polypectomy, endoscopic mucosal resection (EMR) and piecemeal polypectomy in 679 patients from 1983 to 1999, and postpolypectomy complications and its rate were evaluated. RESULTS: 1) Postpolypectomy bleeding occured 18 cases of 1293 polypectomies (1.4%), including 10 cases of initial bleeding and 8 cases of delayed bleeding. In 9 cases (0.7%) of them hemostatic therapy were required. In delayed bleeding most cases (75%) of them occured within 66 hours after polypectomy. 2) Postpolypectomy bleeding occured in 10 cases of 982 polypectomies (1.0%) below 0.9 cm in polyp diameter, 5 cases of 242 polypectomies (2.1%) between 1.0 cm and 1.9 cm in polyp diameter and 3 cases of 69 polypectomies (4.3%) more than 2.0cm in polyp diameter (p<0.05). 3) There were no significant correlation between postpolypectomy bleeding and polypectomy methods (p=0.06) and between postpolypectomy bleeding and gross type of polyps (p=0.40) statistically. 4) Postpolypectomy perforation occured in 1 case of 1293 polypectomies (0.1%). Estimated overall postpolypectomy complication rate including bleeding and perforation was 1.5%. CONCLUSIONS: Colonoscopic polypectomy is a relatively safe method in removing colonic polyp and its complication is related to size of polyp.
