Suitable patients for single-port laparoscopic adrenalectomy : optimal cut-off value for body mass index

抄録

Introduction and Objective

  In this study, we clarified patients suitable for single-port laparoscopic adrenalectomy by focusing on the optimal cut-off values of the body mass index (BMI).

Methods

  A retrospective study was conducted on 126 consecutive patients who underwent single-port adrenalectomy. We re-evaluated all medical records and surgical videos. The pneumoperitoneum time (PT) was employed as an objective index for the assessment of surgical difficulty.

Results

  The total mean PT was 84 minutes. In 27 patients with a BMI less than 20 kg/m², the mean PT was 71 minutes, whereas the mean PT was 104 minutes in 9 patients with a BMI exceeding 28 kg/m².

Conclusions

  Our results suggested that patients with a BMI less than 20 kg/m² are suitable for novice surgeons. Conversely, even experienced surgeons should carefully consider performing single-port surgery on patients whose BMI exceeds 28 kg/m².
