Laparoscopic appendectomy is superior to open appendectomy in obese patients.

Background: There are minimal data comparing laparoscopic appendectomy (LA) with open appendectomy (OA) in obese patients.

Methods: We reviewed consecutive adult patients from 2003 to 2005 who underwent an appendectomy at a University-affiliated teaching hospital. Obesity was defined as a body mass index of 30 or greater. Outcome measures included length of stay, surgical times, intra-abdominal abscesses, wound infections, and hospital charges.

Results: There were 116 patients with a mean body mass index of 35. Eighty-five patients underwent LA, 12 were converted to open, 4 of 12 (31%) were perforated. Thirty-one patients underwent OA. Overall, 21 (18%) were perforated. Length of stay for LA was better, 3.4 days versus 5.5 days for OA (P = .02), and wound closure rate was better, 90% for LA versus 68% for OA (P < .01). Other outcome measures were equivalent.

Conclusions: LA is associated with shorter lengths of stay, fewer open wounds, and equivalent hospital charges and intra-abdominal abscess rates; and should be considered the procedure of choice for obese patients with appendicitis.
