Abstract

Aim: To compare the characteristics of two single-incision methods, and conventional laparoscopy in cholecystectomy, and demonstrate the safety and feasibility.

Methods: Three hundred patients with gallstones or gallbladder polyps were admitted to two clinical centers from January 2013 to January 2014 and were randomized into three groups of 100: single-incision three-device group, X-Cone group, and conventional group. The operative time, intraoperative blood loss, complications, postoperative pain, cosmetic score, length of hospitalization, and hospital costs were compared, with a follow-up duration of 1 mo.

Results: A total of 142 males (47%) and 158 females (53%) were enrolled in this study. The population characteristics of these three groups is no significant differences exist in terms of age, sex, body mass index and American Society of Anesthesiology (P > 0.05). In results, there were no significant differences in blood loss, length of hospitalization, postoperative complications.The operative time in X-Cone group was significantly longer than other groups.There were significant differences in postoperative pain scores and cosmetic scores at diffent times after surgery (P < 0.05).

Conclusion: This study shows that this two single-incision methods are safe and feasible. Both methods are superior to the conventional procedure in cosmetic and pain scores.
