The Application Of The Pre Purse-string Suture Technique In The Endoscopic Treatment Of The Patients With Cavity Out Growth Gastric Lesions

Objective:To investigate the clinical effect of the pre purse-string technique in the endoscopic therapy for stomach extra cavity growth type lesions.The pre purse-string technique is completed by the combination of metal clip and nylon rope.Methods:The clinical data of 27 patients with stomach extra cavity growth type lesions in the digestive endoscopy center of Renmin Hospital of Wuhan University from August 2016 to October were analyzed retrospectively.Results:There are 15 patients in pre purse-string group,3 cases gastric antrum,6 gastric body and 6 gastric fandus.The lesions ranged from 1.5cmx1.5cm～4.0cmx4.0cm with an average size of 2.5cm×3.2 cm.There are 12 cases in purse-string group,3 gastric antrum,5 gastric body and 4 gastric fundus,The lesions ranged from 1.3cm×l.5cm～3.0cmx3.7cm with an average size of 2.4cm×3.0cm.All patients were successfully completed endoscopic surgery,the operation time was 28.0-43.0(35.8±6.1)min in pre purse-string group,and 45.6～68.8(48.8±5.3)min in purse-string group.No obvious postoperative complications occurred.Conclusion:The clinical effect of "pre purse-string" technique in endoscopic treatment of patients with extra cavity growth gastric disease is well and worthy of promotion.
