Therapeutic effect of the pre-purse-string suture on gastric lesions of external growth under endoscopy / 中华消化内镜杂志

ABSTRACT

Objective To investigate the clinical effect of "pre-purse-string" suture on submucous gastric lesions of external growth type in endoscopic patients. Methods Clinical data of 27 patients with gastric lesions of external growth type admitted to the digestive endoscopy center of Renmin Hospital of Wuhan University from August 2016 to October 2016 for endoscopic submucosal dissection ( ESD ) were analyzed. Patients were randomly divided into two groups, the experiment group receiving the "pre-purse-string" suture, the control group receiving purse-string suture after ESD. Mean size of the lesions, procedure time, withdrawal time of gastric decompression, and hospitalization time were compared. Results In the 15 patients of the experiment group, there were 3 cases whose lesions were located in gastric antrum, 6 in gastric body and 6 in gastric fundus. In the 12 cases of the control group, 3 lesions were located in gastric antrum, 5 in gastric body and 4 in gastric fundus. All procedures were successfully completed in endoscopy. No obvious postoperative complications occurred. The mean size of lesions was 2. 5 cm × 3. 2 cm in the experiment group,and 2. 4 cm×3. 0 cm in the control group (P=0. 63). The operation time was 28. 0-43. 0 min (35. 8±6. 1 min) in the experiment group, and 45. 6-68. 8 min (48. 8±5. 3 min) in control group ( P<0. 01) . Conclusion "Pre-purse-string" technique is of clinical effect on gastric submucosal tumor of external growth.
