A comparative study of multiport versus laparoendoscopic single-site adrenalectomy for benign adrenal tumors

Abstract

The results demonstrate that LESS adrenalectomy is as safe and effective as conventional multiport laparoscopic adrenalectomy for benign adrenal tumors. In addition, LESS adrenalectomy provides short-term convalescence advantages over multiport laparoscopic adrenalectomy.

The learning curve of laparoendoscopic single-site adrenalectomy: an analysis of over 100 cases

“…LESS-A was recently reported to be superior to CLA and so has become more common [4][5][6][7][8][9][10][11][12][13][14][15][16]. However, in spite of the technical difficulty of LESS-A, little is known BMI body mass index, VFA visceral fat area, TFA total fat area, ASA American Society of Anesthesiologists, APA aldosterone-producing adenoma, POD postoperative day about its learning curve and the factors associated with the outcomes of the procedure during the learning period.…”

“…Hirano et al [3], many studies have found that LESS-A has advantages over CLA [4][5][6][7][8][9][10][11][12][13][14][15][16]. At our institution, LESS-A was introduced in 2009.…”

Clinical evaluation of a novel commercial single port in laparoendoscopic single-site surgery

“…Without a functional single port or ergonomically feasible laparoscopic instruments for LESS, unsatisfactory pneumoperitoneal pressure or nonergonomic instruments will impair the procedural efficiency and possibly increase intraoperative complications. 11 Therefore, a comparative study to test existing single-access systems and instruments is essential before these expensive novel devices are widely adopted clinically.…”

“…According to our previous experience, the time required to set up a homemade single port is approximately 5e10 minutes. 9,11 To set up a homemade single port, several complicated steps such as surgical glove design/trimming, glove snapping, and trocar securing ligature are required, all of which are time-consuming (or time-limiting) procedures and require a certain amount of experience. If these steps are not carefully executed, gas leakage and port and trocar loosening may cause problems when performing LESS.…”

A Systematic Review and Meta-Analysis of Current Evidence Comparing Laparoendoscopic Single-Site Adrenalectomy and Conventional Laparoscopic Adrenalectomy

“…9 Several nonrandomized comparative series have been published in attempt to compare the outcomes of LESS-A with conventional LA in recent years; however, these results are inconsistent and, furthermore, their reported patient samples are still not large. 7,8,[10][11][12][13][14][15][16] Therefore, it is still unclear whether LESS-A is a truly less invasive and more feasible minimally invasive approach compared with conventional LA.…”
