PURPOSE: Laparoscopic gastric wedge resection (LWR) is being increasingly performed as a safe and effective treatment for gastric submucosal tumors (SMTs). However, there are few studies on the factors associated with operation time of LWR for gastric SMTs. The purpose of this study was to determine the factors associated with the operation time of LWR for gastric SMTs. METHODS: Between June 2001 and December 2008, 58 patients with gastric SMTs underwent LWR. We analyzed the clinicopathologic data, perioperative parameters and outcomes, and surgeon's experience retrospectively. We also analyzed the factors associated with the operation time of LWR for gastric SMTs. RESULTS: Among 58 patients that underwent LWR, exogastric wedge resection (n=48) was mainly performed. Transgastric wedge resection (n=8) took the longest amount of time. Intraoperative GFS (n=7) was frequently performed for smaller tumors. When the tumor was located at the cardia and fundus, more time was needed for LWR of the SMTs. There was no correlation of the operation time with the clinicopathologic data and surgeon's experience; however, the tumor location (axis) and the approach used for the resection of the stomach were statistically correlated with the operation time. CONCLUSION: The operation time of LWR for gastric SMTs was related to the tumor location (according to gastric axis) and the approach used for the resection of the stomach. If the tumor location was identified precisely and the proper approach for resection of the stomach was determined preoperatively, the operation time of LWR for gastric SMTs might be reduced.

Breaking in the site of connection of esophage and cardia is a rare condition in the close abdomen trauma with a high mortality. Its cause is usually a sudden rise of pressure in the abdomen cavity or an error in operation. Early diagnosis is most importance. Tomography is helpful to diagnose the emphysema in the chest in abdomen surgery is an approach od choise

BACKGROUND/AIMS: Endoscopic mucosal resection can cure early gastric cancer. The risk of lymphatic metastasis is related to the depth of submucosal invasion by the mucosal malignancy, with a resection depth of 500 micrometer generally accepted as a safe cut-off. However, excessive thinning induced by stretching of the resected tissue sometimes preventing a precise diagnosis. We studied the effects of stretching on different layers and sites of gastric tissue. METHODS: Porcine stomachs were cut into 2.0x2.0 cm pieces, and pieces from body were stretched to 2.5, 3.0, and 3.5 cm. Pieces from the cardia, body, and antrum were also stretched to 3.0 cm. The thickness of each layer was measured and analyzed statistically. RESULTS: Whole gastric wall and submucosal layers showed gradual thinning, with stretching to 3.5 cm tearing the tissues and resulting in imperfect extension. The submucosa was thinner in body tissue than in cardia and antrum tissues. Stretching to 3.0 cm induced a consistent decrease in submucosal thickness (30-70%). The change in thickness varied widely between individual samples. CONCLUSIONS: A resection margin of 500 micrometer might be insufficient for the complete removal of malignancy. Moreover, the thickness of the submucosal layer differs with the gastric site and between individuals. Future studies are needed to confirm the findings in human tissue.

BACKGROUND AND AIMS: The coiled stent is designed to allow removal in the event that stent malposition or migration occurs in patients with an inoperable malignant esophageal obstruction. There is limited published material on the EsophaCoilTM, especially with regard to its removability. A novel method for endoscopic removal of migrated EsophaCoilTM prosthesis is herein described. METHODS: Seven instances of migration occurred in 19 patients who had undergone coiled stent placement for carcinoma of the distal esophagus or gastric cardia. The stents had migrated into the stomach in 6 cases and the stent was at the rectosigmoid junction in 1 patient. The migrated stents were removed endoscopically using a conventional method in 3 cases, and the Song's stent introducer with a metal tip and overtube under fluoroscopic guidance, in the remaining 4 patients. RESULTS: Using the new endoscopic removal technique, migrated stents were successfully removed in 4 patients after conventional methods failed. There were no complications. CONCLUSIONS: An EsophaCoilTM stent, migrating into the stomach or rectum, could be removed easily by this new method using the overtube and Song's stent introducer.

BACKGROUND/AIMS: There was some technical difficulty in applying the hemoclip on the posterior wall of the body, cardia of the stomach and posterior wall of duodenum because the angle of approach was tangential. Use of transparent cap on the tip of the endoscope could reduce some of these problems. The purpose of this study was to examine the efficacy of endoscopic hemoclipping using a transparent cap. METHODS: From August 1997 to July 2000, 74 patients with bleeding peptic ulcer and stigmata of recent hemorrhage were treated with endoscopic hemoclipping. There was technical difficulty in applying the hemoclip in 18 patients and the transparent cap was used. RESULTS: There was no statistically significant difference between the patients treated with cap and the patients treated without cap in initial hemostasis rate (91.1% vs 94.4%), rebleeding rate (11.8% vs 11.7%), and permanent hemostasis rate (92.9% vs 94.4%). CONCLUSIONS: Use of transparent cap on the tip of the endoscope was an efficient method when the angle of approach was tangential.

Epithelial gastric polyps can be categorized as being either hyperplastic or adenomatous. Hyperplastic polyps accounts for 75~90% of gastric polyps. In contrast to the adenomatous polyps, the potential of a malignant transformation of hyperplastic polyps was originally believed to be quite low (an incidence of 1.5~2.1%), which is considerably lower than that of an adenoma of the stomach. Most of reported cases of a hyperplastic gastric polyp with a transformation to adenocarcinoma were well differentiated histopathologically. There are few reports of a hyperplastic polyp in which malignant changes developed during the endoscopic surveillance. We report a rare case of a 1.2 cm sized moderately differentiated adenocarcinoma arising in a hyperplastic polyp on the cardia in the stomach with a brief review of the relevant literature.

Sarcomatoid carcinoma is a rare neoplasm of epithelial origin but consists partly of variable differentiated tumor cells of mesenchymal origin. Accurate diagnosis, including differentiation from adenocarcinoma or gastrointestinal stromal tumor, is difficult. We experienced three cases of sarcomatoid carcinoma of the stomach, and describe the radiological and pathologic findings. One case involved a polypoid mass in the antrum, another a mass with a large ulcer mimicking a Bormann type-II adenocarcinoma in the body, while in the third case, an intraluminal bulky mass arising from the cardia of the stomach was present. This was not differentiated from cancer or stromal tumor.
