Minilaparoscopic Versus Conventional Laparoscopic Cholecystectomy
Laparoscopic cholecystectomy is one of the most commonly performed operations in general surgery and is considered the standard of care for cholecystectomy for benign biliary disease. The laparoscopic approach to cholecystectomy, when compared to open surgery, is associated with less postoperative pain, quicker recovery time and an improved cosmetic result.
Most commonly, laparoscopic cholecystectomy is performed using a 10-12mm port in the umbilicus with 3 additional ports consisting of either three 5mm ports, or a combination of two 5mm ports and one 10mm port. A new technique called minilaparoscopic (also referred to as needlescopic) surgery has recently emerged. Minilaparoscopic surgery replaces 5mm trocars with smaller 3mm trocars. Surgery using these smaller trocars is hypothesized to further reduce postoperative pain and recovery time as well as improve cosmetic results following laparoscopic surgery. Our goal is to compare these outcomes in a randomized trial comparing conventional to minilaparoscopic cholecystectomy.

- Post-operative pain [ Time Frame: First seven days post-op, 3 weeks post-op ]Post-operative pain will be assessed during the first week post-operatively using a diary that will be provided to patients. In this diary, patients will score their pain daily using a visual analog scale (0=no pain and 10=severe pain) and record use of pain medications for the first seven days post-operatively. Patients will again be asked to score their pain using the visual analog scale at the regularly scheduled follow-up visit three weeks post-op.
- Time to recovery [ Time Frame: 3 weeks post-operatively ]Time to recovery (return to baseline level of activity) will be evaluated by comparing baseline physical activity scores to physical activity scores determined at the follow-up visit three weeks post-op. Physical activity scores will be obtained using the validated CHAMPS questionnaire (2)
- Cosmetic result [ Time Frame: 3 months post-operatively ]Cosmetic result will be evaluated using a scar assessment questionnaire (3), that will be administered by the study coordinator at the routine post-op visit as well as at three months by telephone
- Operative complications [ Time Frame: First 3 months post-op ]Intra-operative, in-hospital (if applicable) and postoperative complications will be recorded and graded according to the Clavien Classification. Superficial and deep incisional surgical site infections will be defined according to the CDC definition.
- Operative technique [ Time Frame: Recorded at visit 3 weeks post-op ]Conversion to conventional laparoscopic technique or open procedure will be recorded at the time of operation.
- Length of operation [ Time Frame: Recorded at visit 3 weeks post-op ]The time necessary to complete the intervention will be recorded
