Minilaparotomy vs. laparoscopic cholecystectomy: results of a randomized clinical trial

Currently, laparoscopic cholecystectomy is considered the gold standard for treatment of gallstones with advantages in regard to postoperative pain, hospital stay, early return to activities of daily living and acceptable cosmetic results. Open cholecystectomy in the form of minilaparotomy may be an effective alternative for the management of symptomatic cholelithiasis. We undertook this study to compare the results of laparoscopic cholecystectomy and minilaparotomy cholecystectomy techniques. methods: We conducted a randomized clinical trial between January 2009 and December 2009. We included patients with symptomatic cholelithiasis divided into two groups: group A--minilaparotomy and group B--laparoscopic cholecystectomy. End-point variables were age, gender, pre- and postoperative diagnosis, operative time, conversion or extension, hospital stay, complications and pain. Statistical analysis included Fisher's exact test, χ(2) test and Student t test.

There were 88 patients with cholelithiasis: 37 men and 51 women. Mean age was 45.65 years. There were 45 patients in Group A and 43 patients in Group B. Mean operative time was 79.02 min for minilaparotomy and 86.04 min for laparoscopic cholecystectomy (p = 0.33). Average hospital stay was 2.75 days for minilaparotomy and of 2.02 days for laparoscopy (p = 0.60). Complications of minilaparotomy were demonstrated in 6.6% of patients and for laparoscopic cholecystectomy in 16.3% of patients (p = 0.16). There were three extensions and five conversions.

Minilaparotomy cholecystectomy has results similar to laparoscopic cholecystectomy.
