Retrospective observational study comparing hand-assisted, retroperitoneal and trans-abdominal laparoscopic adrenalectomy

Abstract Aim Laparoscopic adrenalectomy is considered the optimal approach for most lesions. Various subsets of minimally invasive are practiced in UK, including trans-abdominal (TLA), hand-assisted (HLA) and retroperitoneal (RLA) laparoscopic procedures. We aimed to examine relative operative outcomes between 3 techniques. Methods performed a retrospective observational review contemporaneously maintained databases from two nearby institutions establish differences any size lesion. Statistical analysis was undertaken using R v3.6.0. Results Two hundred ninety-seven patients underwent were included (45 RLA, 77 HLA 175 TLA). There no significant groups institution location, wound infection, intra-operative bleeding, blood product requirements, visceral injury, open conversion, re-operation, incisional hernia, laterality lesion, oncological medical complications. Boxplots revealed wider spread increased mean operating time TLA, with less difference operation RLA groups. This confirmed by an overall finding Kruskal-Wallis rank sum test (p=<0.001) pairwise comparisons Wilcoxon bonferroni correction multiple testing which demonstrated TLA (p<0.001), but not (p=1.000). Conclusion Minimally can safely be showed longer time. The otherwise or outcomes.
