Underestimation of endoscopic size in large gastric epithelial neoplasms: Jae Sun Song, Byung Sun Kim, Min A Yang, Young Jae Lee, Gum Mo Jung, Ji Woong Kim, Jin Woong Cho; Clin Endosc 2022;55(6):760-766. Published online May 19, 2022; DOI: https://doi.org/10.5946/ce.2021.269

Background
/Aims: Endoscopic submucosal dissection (ESD) is an effective method for resecting gastric adenomas and adenocarcinomas. A significant discrepancy was observed between endoscopic and pathological sizes in samples obtained from patients undergoing ESD. This study elucidates the factors affecting size discrepancy after formalin fixation.
Methods
The records of 64 patients with 69 lesions were analyzed, including 50 adenomas and 19 adenocarcinomas. Data on location, gross shape, histology, and size after fixation in formalin were collected.
Results
The mean size of the resected specimen appeared to decrease after formalin fixation (37.5 mm prefixation vs. 35.8 mm postfixation, p<0.05). The mean long axis diameter of the lesions was 20.3±7.9 mm prefixation and 13.4±7.9 mm postfixation. Size differences in lesions smaller than 20 mm were significantly greater than those in lesions larger than 20 mm (7.6±5.6 mm vs. 2.5±5.8 mm, p<0.01). In multivariate analysis, a tumor size of ≥20 mm was found to be an independent factor affecting size postformalin fixation (p<0.05).
Conclusions
The endoscopic size of lesions before ESD may be underestimated in tumors larger than 20 mm in size. Therefore, increased attention must be paid during ESD to avoid instances of incomplete resection.

An Intractable Caustic Esophageal Stricture Successfully Managed with Sequential Treatment Comprising Incision with an Insulated-Tip Knife, Balloon Dilation, and an Oral Steroid: Woong Ki Lee, Byung Sun Kim, Min A Yang, So Hee Yun, Young Jae Lee, Ji Woong Kim, Jin Woong Cho; Clin Endosc 2016;49(6):560-563.

Abstract PDF PubReader ePub

Bougie or balloon dilation is a good short-term treatment for caustic esophageal strictures, although recurrence after dilation occurs in approximately 30% of these cases. Therefore, long-term treatment options are required in some cases, and endoscopic incisional therapy has been used for patients with an anastomotic stricture in the gastrointestinal tract. A 58-year-old woman presented with severe swallowing difficulty because of a caustic esophageal stricture, which was caused by accidental exposure to anhydrous acetic acid at infancy. She had undergone several previous bougie and balloon dilations but the stricture did not improve. We performed sequential treatment comprising incision with an insulated-tip knife, balloon dilation, and an oral steroid, which resulted in the patient’s symptoms markedly improving. Thus, we report this case of an intractable caustic esophageal stricture, which was successfully treated using combined endoscopic sequential treatment.

Intramural Gastric Abscess Caused by a Toothpick Presenting as a Subepithelial Tumor: Wang Guk Oh, Mun Chul Kim, Hyun Ju Yoon, Jae Woo Park, Min A Yang, Cheon Beom Lee, Ji Woong Kim, Jin Woong Cho; Clin Endosc 2014;47(3):254-257. Published online May 31, 2014; DOI: https://doi.org/10.5946/ce.2014.47.3.254

Abstract PDF PubReader ePub

In the present report, we describe an unusual case of an intramural gastric abscess caused by a foreign body, detected in the form of a subepithelial tumor. A 64-year-old woman was referred to our gastroenterology clinic for further evaluation of a gastric subepithelial tumor. The patient presented with a 1-month history of sustained dull epigastric pain. Esophagogastroduodenoscopy revealed an ill-demarcated, round, smooth, protruding lesion with a small central erosion on the great curvature of the proximal antrum. Endoscopic ultrasonography indicated the presence of an ovoid, heterogeneous, hypoechoic lesion with small echogenic foci located in the submucosa and muscularis propria layers. An abdominal computed tomography scan showed focal gastric wall thickening and regional lymph node enlargement. Endoscopic submucosal dissection was performed for definite diagnosis and management. Thus, we detected a toothpick and removed it using grasping forceps. The final diagnosis was an intramural gastric abscess caused by a toothpick.

Cronkhite-Canada Syndrome Associated with Serrated Adenoma and Malignant Polyp: A Case Report and a Literature Review of 13 Cronkhite-Canada Syndrome Cases in Korea: So Hee Yun, Jin Woong Cho, Ji Woong Kim, Joong Keun Kim, Moon Sik Park, Na Eun Lee, Jae Un Lee, Young Jae Lee; Clin Endosc 2013;46(3):301-305.

Abstract PDF PubReader ePub

Cronkhite-Canada syndrome (CCS) is a rare nonfamilial polyposis syndrome characterized by epithelial disturbances both in the gastrointestinal tract and in the epidermis. The pathologic finding of the polyp is usually a hamartomatous polyp of the juvenile type; however, the possibility of serrated adenoma associated malignant neoplasm was reported in some Japanese cases. Up till now in South Korea, 13 CCS cases have been reported, but there was no case accompanied by the colon cancer. We report the first case of CCS associated with malignant colon polyp and serrated adenoma in Korea. A 72-year-old male patient who complained of diarrhea and weight loss was presented with both hands and feet nail dystrophy, hyperpigmentation, and alopecia. Endoscopic examination showed numerous hamartomatous polyps from the stomach to the colon. The pathologic results confirmed colon cancer and serrated adenoma. Helicobacter pylori eradication and prednisolone was used. Thus, the authors report this case along with a literature review.
