Outcome of Laparoscopic Adrenalectomy in Obese Patients

Abstract

Objectives: To compare early morbidity of obese and nonobese patients with minimally invasive adrenalectomies.

Method: Retrospective study of a prospectively maintained database, between June 2003 - December 2012, in a universitary affiliated tertiary hospital. Selection criteria: Minimally invasive adrenalectomy. Obese patients were defined as BMI over 30 kg/m2.

Results: From 205 patient with laparoscopic adrenalectomies we counted 30 obese patients (OG), 25 of them female and only 5 men with a median age of 54,20 years versus 47,94 years for nonobese group (NOG) (p=0.008). In OG were 15 right sided tumor, 11 on the left side and 4 bilateral all treated with transperitoneal antero-lateral approach. Median operating time was 92.20 minutes for OG versus 91.13 minutes for NOG (p=0.924). In OG, 5 patients had previous abdominal surgeries and we counted 4 conversion to open surgery, 2 postoperative complications (6.6%) and no mortality. All OG patients have diverse comorbidities, 50% of them more then 3. Median specimen size was 5.92 cm for OG versus 4.85 cm for NOG (p=0.057). The histology of OG was: adenoma 11 cases, hiperplasia 13 cases and pheochromocytoma 6. In NOG we had: postoperative hospital stay was 6.57 days in OG versus 4.11 days in NOG (p=0.009).

Conclusions: Although obese patients had a higher rate for early morbidities, the minimally invasive approach has particular benefits for them. Although postoperative hospital stay was significantly longer, we believe that advantages of minimal invasive surgery for obese patients remains valid even in a BMI over 30.
