[Application of purse string suture with Harmonious Clips and Olympus endoloop in single channel endoscopy for large gastric antrum mucosa defect].

Objective

To evaluate the feasibility and safety of purse string suture with Harmonious Clips and Olympus endoloop in single channel endoscopy for large gastric antrum mucosa defect.

Methods

A total of 33 patients who underwent ESD of gastric antrum in single channel endoscopy at the First people's Hospital of Wujiang District from January 2015 to April 2018 were retrospectively analyzed. Everyone had one lesion, and the diameters were all more than 3 cm. After the resection and hemostasis, purse string suture with Harmonious Clips and Olympus endoloop or no suture in study group (n=16) and the control group (n=17). The degree of abdominal pain, postoperative gastrointestinal decompression time, incidence of delayed hemorrhage, postoperative hospital stay and the healing rate were observed and compared.

Results

All patients successfully completed resection, no perforation occurred, and all the lesions were resected completely in one time. All patients in the study group were sutured successfully. The abdominal pain score on the first day after operation was (2.7±0.7) in the study group, and (3.6±0.8) in the control group(t=3.686, P=0.001). The mean time of postoperative gastrointestinal decompression was (1.6±0.5) days in the study group, while (2.4±0.7) days in the control group(t=3.675, P=0.001). No delayed bleeding occurred in the study group, while 5 cases in the control group had delayed bleeding. The rate of delayed hemorrhage was 29.4% in control group, 4 cases successfully achieved hemostasis through endoscopy therapy, 1 case was given surgical intervention after ineffective endoscopic hemostasis(P=0.044). The average postoperative hospital stay were (6.2±1.1) days and (5.9±2.0) days respectively (t=0.423, P=0.675). Two months after the operation, the two groups of patients reviewed the gastroscopy, the results showed that, all wounds in the study group were healed completely, the healing rate was 100%. There were 6 cases of incomplete wound healing in the control group, the healing rate was 64.7%(P=0.018). No recurrence was found after 6 months of operation through reviewing gastroscopy. Conclution: It indicates good feasibility and efficacy about the purse string suture with Harmonious Clip and Olympus endoloop in single channel endoscopy for large gastric antrum mucosa defect. It is safe and reliable, worth of being generalized.
