Colonoscopic polypectomy is effective in decreasing the incidence and mortality of colorectal cancer (CRC). Premalignant polyps discovered during colonoscopy are associated with the risk of metachronous advanced neoplasia. Postpolypectomy surveillance is the most important method for the management of advanced metachronous neoplasia. A more efficient and evidence-based guideline for postpolypectomy surveillance is required because of limited medical resources and concerns regarding colonoscopy complications. In these consensus guidelines, an analytic approach was used to address all reliable evidence to interpret the predictors of CRC or advanced neoplasia during surveillance colonoscopy. The key recommendations state that the high-risk findings for metachronous CRC following polypectomy are as follows: (1) adenoma ≥10 mm in size; (2) 3 to 5 (or more) adenomas; (3) tubulovillous or villous adenoma; (4) adenoma containing high-grade dysplasia; (5) traditional serrated adenoma; (6) sessile serrated lesion (SSL) containing any grade of dysplasia; (7) serrated polyp of at least 10 mm in size; and (8) 3 to 5 (or more) SSLs. More studies are needed to fully comprehend the patients most likely to benefit from surveillance colonoscopy and the ideal surveillance interval to prevent metachronous CRC.

Endoscopic Ultrasound-Guided Perirectal Abscess Drainage without Drainage Catheter: A Case Series
Eun Kwang Choi, Ji Hyun Kim, Seung Uk Jeong, Soo-Young Na, Sun-Jin Boo, Heung Up Kim, Byung-Cheol Song
Clin Endosc 2017;50(3):297-300.   Published online April 11, 2017
AbstractAbstract PDFPubReaderePub
A perirectal abscess is a relatively common disease entity that occurs as a postsurgical complication or as a result of various medical conditions. Endoscopic ultrasound (EUS)-guided drainage was recently described as a promising alternative treatment. Previous reports have recommended placement of a drainage catheter through the anus for irrigation, which is inconvenient to the patient and carries a risk of accidental dislodgement. We report four cases of perirectal abscess that were successfully treated with only one or two 7 F double pigtail plastic stent placements and without a drainage catheter for irrigation.

Clipping for the Prevention of Immediate Bleeding after Polypectomy of Pedunculated Polyps: A Pilot Study
Sun-Jin Boo, Jeong-Sik Byeon, Seon Young Park, Jong Sun Rew, Da Mi Lee, Sung Jae Shin, Dong Uk Kim, Geum Am Song
Clin Endosc 2012;45(1):84-88.   Published online March 31, 2012
AbstractAbstract PDFPubReaderePub

Immediate postpolypectomy bleeding (IPPB) increases the procedure time and it may disturb performing a safe polypectomy. The purpose of this study is to investigate whether clipping before snare polypectomy of large pedunculated polyps is useful for the prevention of IPPB.


This is a single arm, pilot study. We enrolled patients with pedunculated colorectal polyps that were 1 cm in size or more from 4 university hospitals between June 2009 and June 2010. Clips were applied at the stalk and snare polypectomy was then performed. The complications, including IPPB, were investigated.


Fifty six pedunculated polyps in 47 patients (Male:Female=36:11; age, 56±11 years) were included. The size of the polyp heads was 17±8 mm. Tubular adenoma was most common (57%). The number of clips used before snare polypectomy was 2±0.5. The procedure was successful in all cases. IPPB occurred in 2 cases (3.6%), and both of these were managed by additional clipping. Delayed bleeding occurred in another one case (1.8%), which improved with conservative treatment. No perforation occurred.


We suggest that clipping before snare polypectomy of pedunculated polyps may be an easy and effective technique for the prevention of IPPB, and this should be confirmed in large scale, prospective, controlled studies.
