Clinical study of improved transumbilical singl-pore laparoscopic cholecystectomy by conventional instruments

Objective To investigate the effect of clinical application, feasibility and generalization of improved transumbilical single-pore laparoscopic cholecystectomy (TUSILC) with conventional instruments. Methods A total of 816 patients underwent improved TUSILC with conventional instruments (observation group) and 820 patients received conventional laparoscopic treatment (control group) from March 2014 to February 2019 in the First People’s Hospital of Yibin were selected. The surgical indicators, postoperative results, and hospitalization expenses were compared between the two groups. Results All patients recovered well and no complications such as hemorrhage, bile leakage, abdominal infection and incisional hernia occurred. There were no significant differences in blood loss, postoperative hospitalization time and hospitalization expenses between the two groups (P>0.05). The operation time in the observation group was (40.3±11.2) minutes, the postoperative pain score was (2.3±1.4)points, and the recovery satisfaction degree of navel incision was(4.8±0.5)points, which was statistically significant compared with the (31.2±8.4)min, (5.0±1.5)points and (3.9±0.4)points in the control group (P<0.05). Conclusions Improved transumbilical single-pore laparoscopic cholecystectomy by conventional instruments has small surgical trauma and invisible scars after surgery. The patients feel less pain and are satisfied with the treatment cosmetic result. Key words: Cholecystectomy, laparoscopy, single hole; Transumbilical access; Conventional instruments
