Abstract
Objective To design a hemostatic clip and evaluate its efficacy and success rate of closure of stomach wall defect after full thickness resection (FTR). Methods A full thickness circular or linear resection (3 to 5 cm) was made on each model's antrum with needle knife and insulated-tip knife. The specimens were divided into 2 groups, using either an interrupted or continuous suturing method. Then the closure condition, suturing time, number of clips required and success rate of closure were compared. Results All 12 defects were successfully closed. The average closing time of interrupted and continuous suturing group were 13.33±1.09 and 10.17±2.11 minutes, and the mean number of clips used were 4.67±0.82 and 2.67±0.82. The success rate was 100%. Conclusion This newly designed clip is a fast, reliable and convenient tool for stomach wall defect closure after FTR. Key words: Suture techniques; Hemostatic clip; Stomach wall defect; Treatment
