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.

The most important indication for the removal of the lead-electrode system is the presence of an infection. When an infection occurs, the entire pacemaker system including the impluse generator and lead-electrode system should be removed. The entrapped electrode can be removed by a continous traction, by the use of forceps, snares or baskets, by the use of a locking stylet or a dilator sheath, and by an operation. We report a case that underwent a removal of an entrapped transvenous pacemaker electrode by the use of snaring technique.

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.

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.

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.

Most of subepithelial tumor (SET) in stomach is incidentally found during esophagogastroduodenoscpic examination. Even small gastric SETs less than 2.0 cm might have malignant potential, thus ambiguous cases should be removed and pathologically confirmed for optimal diagnosis and treatment. As endoscopic techniques are developed, endoscopic removal of gastric SETs has been reported increasingly. The endoscopic procedures for resection of gastric SETs include classic methods such as snare polypectomy or incisional enucleation, and more progressive and standard technique such as endoscopic submucosal dissection. For gastric SETs originated from deeper layer including muscularis mucosa, novel procedures such as endoscopic submucosal tunnel dissection and endoscopic full-thickness resection (EFTR) are now being introduced, and cooperation with laparoscopic approach such as laparoscopy- assisted EFTR might be an alternative option to overcome shortcomings of endoscopic procedures only and ensure more safe and complete resection.

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.
