Abstract

Background: Compared with the open procedure, laparoscopic adrenalectomy (LA) is associated with decreased operative time, perioperative complications, and hospital stay. Some regard prior abdominal surgery as a contraindication to LA or suggest a retroperitoneoscopic approach. We studied the effect of prior abdominal surgery on the feasibility and safety of transabdominal LA. Methods: We retrospectively analyzed 246 consecutive LAs performed at four academic centers from 2002 to 2006. Cases were grouped according to prior abdominal surgery (PAS) (n = 92, 37%) or no prior surgery (NPS) (n = 154, 63%). Statistical power was greater than 0.90 to detect the following differences in endpoints: conversion 2%, operating time 22%, and complications 2%. Results: Mean tumor size was 3.3 cm, 8.1% of tumors were larger than 7 cm, and 20% were pheochromocytomas. Prior operations were upper abdominal (37%), lower abdominal (48%), or laparoscopic (15%). There were nine conversions (3.7%), one in the PAS group and eight in the NPS group (p = 0.14), with conversions related to large tumor size and pheochromocytoma (both p < 0.01). Operating time was 158 ± 59 min across groups. The subgroup with prior upper abdominal surgery had nonsignificantly longer operating times compared with the NPS group (183 vs. 165 min, p = 0.16). Operative blood loss was 67 ± 84 ml and the perioperative complication rate was 12.2%, with no differences between groups. Conclusion: Prior abdominal surgery does not impede transabdominal LA. More than one-third of patients requiring adrenalectomy will have had prior abdominal surgery, and these patients should not be denied the benefits of a laparoscopic procedure.
