Lateral laparoscopic adrenalectomy in patients with previous abdominal surgery - single-center experience

Abstract

Introduction: Lateral transabdominal adrenalectomy (LTA) is the most common minimally invasive technique used to treat patients with adrenal tumors. Aim: To analyze intra-operative and post-operative complications and reasons for conversion to open surgery in patients who underwent LTA and had previous abdominal surgery. Material and methods: Five hundred and nineteen patients underwent LTA in our center between 2005 and 2016. We identified a study group of 150 patients, with previous abdominal surgery. We analyzed the frequency of intra-operative and post-operative complications and the reasons for conversion from laparoscopic to open adrenalectomy. Results: The patients' mean age was 58; they underwent LTA due to hormonally active tumors (n = 79, 53%) and non-functioning adrenal tumors (n = 71, 47%). The size of adrenal lesions ranged from 20 mm to 90 mm. Seventy-eight (52%) adrenal lesions were found in the right adrenal gland, and 72 (48%) lesions in the left adrenal gland. The mean operating time was 130 min. The mean stay in hospital was five days. The intra-operative complications included blood pressure fluctuations (n = 32), abnormal vascular supply of the adrenal glands causing difficulties with dissections (n = 3), and respiratory problems (n = 1). Two (1.3%) patients had post-operative bleeding at the site of removed adrenal glands; 1 patient had an exacerbation of asthma postoperatively. Of the 150 patients analyzed, 3 (2%) required conversion to open adrenalectomy. The conversions were not caused by abdominal adhesions. Conclusions: Lateral transabdominal adrenalectomy is feasible and safe in patients with previous abdominal surgery. In our study, conversion from laparoscopic to open adrenalectomy was not caused by abdominal adhesions.
