To evaluate the yields and utility of 19-gauge (G) Trucut biopsy (TCB) versus 22 G fine needle aspiration (FNA) for diagnosing gastric subepithelial tumors (SETs).
We retrieved data for 152 patients with a gastric SET larger than 2 cm who had undergone endoscopic ultrasonography (EUS)-guided 19 G TCB (
A specific diagnosis was made for 76 gastrointestinal stromal tumors (GISTs) and 51 non-GIST SETs. The diagnostic yield of TCB was greater than that of FNA (77.8% vs. 38.7%,
Nineteen-gauge TCB is safe and highly valuable for diagnosing gastric SETs larger than 2 cm if technical failure can be avoided.

Gastrointestinal Stromal Tumors of the Small Intestine: Progress in Diagnosis and Treatment Research

Percutaneous endoscopic gastrostomy (PEG) is a method of providing enteral nutrition using endoscopy. The PEG techniques differ according to the insertion method, and include the pull type, push type, and introducer type. The aim of this study was to compare the clinical outcomes associated with the pull-type and introducer-type PEG insertion techniques, which included the adverse events, at our tertiary care center in Korea.
We retrospectively reviewed 141 cases that had undergone PEG insertion at our center from January 2009 to June 2012. The indications for PEG insertion and the acute and chronic complications caused by each type of PEG insertion were analyzed.
The indications for PEG insertion in our cohort included neurologic disease (58.7%), malignancy (21.7%), and other indications (19.6%). Successful PEG insertions were performed on 136 cases (96.5%), and there were no PEG-associated deaths. Bleeding was the most frequent acute complication (12.8%), and wound problems were the most frequent chronic complications (8.8%). There were no statistically significant differences between the pull-type and introducer-type PEG insertion techniques in relation to complication rates in our study population.
PEG insertion is considered a safe procedure. The pull-type and introducer-type PEG insertion techniques produce comparable outcomes, and physicians may choose either of these approaches according to the circumstances.

One of the most important prognostic factors in esophageal carcinoma is lymph node metastasis, and in particular, the number of affected lymph nodes, which influences long-term outcomes. The esophageal lymphatic system is connected longitudinally and transversally; thus, the pattern of lymph node metastases is very complex. Early esophageal cancer frequently exhibits skipped metastasis, and minimal surgery using sentinel node navigation cannot be performed. In Korea, most esophageal cancer cases are squamous cell carcinoma (SCC), although the incidence of adenocarcinoma has started to increase recently. Most previous reports have failed to differentiate between SCC and adenocarcinoma, despite the fact that the Union for International Cancer Control (7th edition) and American Joint Committee on Cancer staging systems both consider these separately because they differ in cause, biology, lymph node metastasis, and outcome. Endoscopic tumor resection is an effective and safe treatment for lesions with no associated lymph node metastasis. Esophageal mucosal cancer confined to the lamina propria is an absolute indication for endoscopic resection, and a lesion that has invaded the muscularis mucosae can be cured by local resection if invasion to the lymphatic system has not occurred.

Stricture frequently occurs after endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma with near- or whole-circumferential mucosal defects, and post-ESD stricture is difficult to treat and usually requires multiple sessions of endoscopic balloon dilatation. Intralesional steroid injection has previously been used to prevent stricture; however, there have been few experiences with this method after near- or whole-circumferential ESD. We present a case of a single session of intralesional steroid injection performed immediately after near-circumferential ESD to prevent post-ESD stricture. After a follow-up period of 6 months, the patient showed good outcome without dysphagia.
