Comparison between single incision and conventional laparoscopic cholecystectomy for uncomplicated cholelithiasis.
OBJECTIVE
To compare surgical outcomes of patients presenting with uncomplicated cholelithiasis and operated by single incision (SILC) or by conventional laparoscopic cholecystectomy (CLC).


METHODS
The series concerned 58 consecutive patients operated between October 2008 and October 2009. There were 11 men and 47 women with a mean age of 47 years and a BMI of 29. Six patients had a past surgical history with a midline incision. The main parameters analysed were duration of operation, morbidity, postoperative pain, return to normal activities and aesthetic result. One month and one year after surgery, the cosmetic result was assessed on a visual analogue scale (VAS), a score between 9 and 10 was considered as an excellent cosmetic result.


RESULTS
A SILC was performed in 26 and a CLC in 32 patients. Patients in the SILC group were characterised by a lower BMI : 25 versus 32 (p <0.001) and by the absence of previous midline incision: 0/26 (0%) versus 6/32 (19%) (p <0.028). Outcomes were similar between groups except the aesthetic result. Multivariate statistical analysis revealed that the percentage of excellent cosmetic result was higher in SILC than in CLC group : respectively 73% (19/26) vs. 28% (9/32) one month postoperatively (OR : 5.3, 95% CI: 1-23, p <0.03) and 92% (22/24) versus 55% (17/31) one year postoperatively (OR : 6.9, 95% CI : 1-46, p < 0.04).


CONCLUSIONS
Our study demonstrates that SILC is a feasible and safe procedure in a selected population. Compared to CLC, the only obvious benefit is a better cosmetic result that is still observed one year after surgery.
