Background:
Trans-umbilical single-port laparoscopic cholecystectomy for chronic gallbladder disease is becoming increasingly accepted worldwide. But so far, no reports exist about the challenging single-port surgery for acute cholecystitis. The objective of this study was to describe our experience with single-port cholecystectomy in comparison to the conventional laparoscopic technique.
Methods:
Between August 2008 and March 2010, 73 patients with symptomatic gallbladder disease and histopathological signs of acute cholecystitis underwent laparoscopic cholecystectomy at our institution. Thirty-six patients were operated on with the single-port technique (SP group) and the data were compared with a control group of 37 patients who were treated with the multi-port technique (MP group).
Results:
The mean age in the SP group was 61.5 (range 21-81) years and in the MP group was 60 (range 21-94) (P=0.712). Gender, ASA status and BMI were not significantly different. The number of white blood cells was different before [SP: 9.2 (range 2.8-78.4); MP: 13.2 (range 4.4-28.6); P=0.001] and after the operation [SP: 7.8 (range 3.5-184.8); MP: 11.1 (range 5-20.8); P=0.002]. Mean operating time was 88 (range 34-174) minutes in the SP group vs 94 (range 39-209) minutes in the MP group (P=0.147). Four patients (5%) required conversion to an open procedure (SP: 1; MP: 3; P=0.320). During the follow-up period of 332 (range 29-570) days in the SP group and 428 (range 111-619) days in the MP group (P=0.044), eleven (15%) patients developed postoperative complications (P=0.745) and two patients in the SP group required reoperation (P=0.154).
Conclusions:
Trans-umbilical single-port cholecystectomy for beginning acute cholecystitis is feasible and the complication rate is comparable with the standard multi-port operation. In spite of our good results, these operations are difficult to perform and should only be done in high-volume centers for laparoscopic surgery with experience in single-port surgery.
