Purpose
This study aims to recognize factors affecting operative and postoperative outcomes in patients undergoing unilateral laparoscopic adrenalectomy performed by using the transabdominal approach.
Methods
From a prospectively collected adrenal database, we performed a retrospective analysis of all patients undergoing unilateral adrenalectomy from July 2002 to December 2011. The outcome measures considered were the following: conversion rate, intra- and postoperative complications, duration of surgery, length of hospital stay, and return-to-work time. Demographic data, American Society of Anesthesiologists score, characteristics of adrenal tumor, and operative and postoperative variables were analyzed to assess their influence on the outcome variables.
Results
A total of 163 laparoscopic adrenalectomies were included. Intraoperative complications, conversion to laparotomy, and postoperative complications were observed in 6.7, 6.1, and 1.8 % of cases, respectively. Conversion to open surgery, intraoperative complications, metastasis, and pheochromocytoma were found to be predictive factors for operative time of >140 min. An operative duration of >140 min was associated with intraoperative complications. Tumor size, intraoperative complications, and adrenalectomy for metastasis significantly increased conversion rate. Hospital stay was extended by operative time of >140 min, conversion to laparotomy, and postoperative complications.
Conclusion
Our study highlights that simple clinical variables, long procedures, and operative complications have a negative impact on procedural outcomes. Based on this, it may be possible to predict cases requiring collaboration with experienced surgeons in order to minimize perioperative morbidity.
