AbstractAbstract PDFSupplementary MaterialPubReaderePub
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 treatment for rectal neuroendocrine tumor: which method is better?
Seung Min Hong, Dong Hoon Baek
Clin Endosc 2022;55(4):496-506.   Published online July 11, 2022
DOI: https://doi.org/10.5946/ce.2022.115
AbstractAbstract PDFPubReaderePub
Recently, research on rectal neuroendocrine tumors (NETs) has increased during the last few decades. Rectal NETs measuring <10 mm without atypical features and confined to the submucosal layer have only 1% risk of metastasis, and the long-term survival probability of patients without metastasis at the time of diagnosis is approximately 100%. Therefore, the current guidelines suggest endoscopic resection of rectal NETs of <10 mm is regarded as a safe therapeutic option. However, there are currently no clear recommendations for technique selection for endoscopic resection. The choice of treatment modality for rectal NETs should be based on the lesion size, endoscopic characteristics, grade of differentiation, depth of vertical involvement, lymphovascular invasion, and risk of metastasis. Moreover, the complete resection rate, complications, and experience at the center should be considered. Modified endoscopic mucosal resection is the most suitable resection method for rectal NETs of <10 mm, because it is an effective and safe technique that is relatively simple and less time-consuming compared with endoscopic submucosal dissection. Endoscopic submucosal dissection should be considered when the tumor size is >10 mm, suctioning is not possible due to fibrosis in the lesion, or when the snaring for modified endoscopic mucosal resection does not work well.

A Rare Case of Early Gastric Cancer Combined with Underlying Heterotopic Pancreas
Jung Bin Yoon, Bong Eun Lee, Dae Hwan Kim, Do Youn Park, Hye Kyung Jeon, Dong Hoon Baek, Gwang Ha Kim, Geun Am Song
Clin Endosc 2018;51(2):192-195.   Published online August 31, 2017
DOI: https://doi.org/10.5946/ce.2017.055
AbstractAbstract PDFPubReaderePub
Heterotopic pancreas in the stomach is usually asymptomatic and benign. Here, we presented a rare case of an early gastric cancer overlying a heterotopic pancreas. A 48-year-old woman underwent esophagogastroduodenoscopy, which revealed a subepithelial mass measuring 2.0×1.5 cm on the gastric antrum with a 1-cm erosive erythematous discoloration on the surface. A biopsy specimen showed moderately differentiated tubular adenocarcinoma. Endosonography showed a heterogeneous hypoechoic mass measuring 1.3×0.6 cm, with indistinct margins in the second and third layers of the gastric wall; anechoic tubular structures within the mass were suggestive of heterotopic pancreas. Distal gastrectomy was performed, which confirmed an early gastric cancer confined to the mucosa, and a separate underlying heterotopic pancreas. Although heterotopic pancreas is most likely benign, careful endoscopic observation of the mucosal surface is necessary to avoid overlooking a coincident early gastric cancer.

Bile Duct Patency Maintained after Intraductal Radiofrequency Ablation in a Case of Hepatocellular Cholangiocarcinoma with Bile Duct Invasion
Sung Yong Han, Geun Am Song, Dong Uk Kim, Dong Hoon Baek, Moon Won Lee, Gwang Ha Kim
Clin Endosc 2018;51(2):201-205.   Published online August 31, 2017
DOI: https://doi.org/10.5946/ce.2017.097
AbstractAbstract PDFPubReaderePub
Combined hepatocellular-cholangiocarcinoma (HCC-CC) with bile duct invasion (BDI) is rare. In unresectable cases, biliary stent placement and photodynamic therapy (PDT) are used for resolving obstructive jaundice. However, stent occlusion remains problematic, and PDT is expensive and time-consuming. Intraductal radiofrequency ablation (RFA) is an emerging procedure for palliation in these patients. It has potential benefits including less expense, lower rates of severe complication, longer maintenance of ductal patency, and easier technique compared with PDT or stenting alone. We report a 67-year-old man who underwent repeated intraductal RFA for HCC-CC and HCC with BDI (HCC-BDI), for whom bile duct patency was maintained without additional biliary procedures.
