PURPOSE: To valuate the value of goose neck snare in removal of foreignbody in endovascular system. METHODS & MATERIAL: Foreignbody removal in endovascular system using goose neck snare were done in 4 cases. In one case, a broken guide-wire was located in left subclaviar vein and in three cases, guide-wires were located in vena cava. RESULTS: Technical success was achieved in all four cases. CONCLUSION: Goose neck snare technique is safe and effective in removal of Foreignbody in endovascular system.

With the improvement of the instrument and technic, the gastrofiberoscope has been used not only in diagnostic purpose but in therapeutic purpose. One purpose of the therapeutic methods is to remove the gastric foreign bodies. So many type and shape of forceps and baakets have been usad. for the same purpose. ifn these easea, we uaed biopsy farcep and snare to remove swallowed toothbrushes, three casea in the stomaeh and one cuse in the duodenurn.

Endoscopic drainage of pancreatic pseudocysts is a new nonsurgical treatment modality. Among the cystogastrostomy and stent related complications, proximal migration of stent is rare and the correction of inserted stent into a pseudocyst is very difficult. We report a correction of an incidentally inserted pigtail stent into pseudocyst using a polypectomy snare.

The snare technique has been used for the removal of ureteral stents. If, however, a stent has migrated to theupper or lower pole calyx, snaring-due to close contact between the stent and the calyceal mucosa or narrow spaceof the renal calyx-is impossible. By using the second suare technique, which involves snaring the previouslyinserted guidewire, the large renal pelvic space can be used for the removal of a migrated ureteral stent. Wedeseribe two cases and discuss the safety and efficacy of this technique.

BACKGROUND/AIMS: Endoscopic mucosal resection (EMR) has been known as a method of local treatment for early gastric cancer (EGC) or gastric adenoma. The purpose of this study was to identify the factors affecting complete resection rate (CRR) of EMR and to identify histological discrepancy between endoscopic biopsy and the resected specimen obtained by EMR. METHODS: Forty four gastric adenomas and twenty seven EGCs in 63 patients were treated by EMR from January, 1999 until August, 2002. We analysed the factors affecting CRR on the basis of location, macroscopic type, size, piecemeal resection, and EMR methods. RESULTS: The CRR in antrum was 72%. The CRR of the method using endoscopic resection with hypertonic saline-epinephrine solution, injection, precutting and snaring (ER-HSE) was 78%. The CRR according to en bloc resection was 77%. Sixty six percents of histological coincidence was noted between the endoscopic biopsy and the resected specimen of gastric adenoma. CONCLUSIONS: In this study, the CRR of the ER-HSE method and the lesion located in antrum is higher than that other groups. Gastric adenoma should be removed by EMR because of histologic discrepancy between the endoscopic biopsy and the resected specimen.

Many reports have shown that endoscopic polypectomy or endoscopic mucosal resection can successfully remove tumor less than 1.0 cm in size. However, most carcinoid tumors in the rectum occur in the submucosal layer so that the entire tumor cannot be completely removed via endoscopic polypectomy or endoscopic mucosal resection. Endoscopic mucosal resection can also cause perforation of the intestinal wall and bleeding. Due to these reasons, instead of these two conventional methods, endoscopic mucosal resection using a ligation device is currently being used for the treatment of rectal carcinoid tumor. Recent studies that used this method have reported that endoscopic mucosal resection of rectal carcinoid tumor by band ligation and the snare resection technique is safe with minimal complications and this is quite useful to completely remove rectal carcinoid tumor.

Endoscopic mucosal resection (EMR) is an endoscopic alternative to surgical resection of mucosal and submucosal neoplastic lesions. Prior to the development of knives, EMR could be performed with accessories to elevate the lesion. After the development of various knives, en bloc resection was possible without other accessories. So, recently, simple snaring without suction or endoscopic submucosal dissection using knife in the epithelial lesions such as adenoma or early mucosal cancer has been performed. However, for easy and complete resection of subepithelial lesions such as carcinoid tumor, a few accessories are needed. Complete resection of rectal carcinoid tumors is difficult to achieve with conventional endoscopic resection techniques because these tumors often extend into the submucosa. The rate of positive resection margin for tumor is lower in the group of EMR using a cap (EMR-C) or EMR with a ligation device (EMR-L) than conventional EMR group. EMR-C and EMR-L (or endoscopic submucosal resection with a ligation device) may be a superior method to conventional EMR for removing small rectal carcinoid tumors.

There are many complications following gastrectomy and one of the most frequent complications is anastomosis site leakage. Postoperative leakage is a serious complication in patients after they undergo gastric surgery. It can lead to the progressive deterioration in the patient's condition and quality of life and the mortality rate is nearly 60%. We encountered a case of a 75 year-old man who had the leakage of the jejunal end of the Roux limb after total gastrectomy. We performed treatment of the leakage endoscopic clipping and detachable snaring. Hemoclips were fixed at the margin of both sides of the lesion. A detachable snare was used to bind both hemoclips, so the interval was made narrow. After snare binding, five hemoclips were used for final closure of the small interval. After treatment, the leakage of the afferent loop end was completely stopped. He resumed an oral intake and was discharged without complications.
