A Canadian centre’s experience with prone retroperitoneoscopic adrenalectomy

Le résumé fourni par la source

Background: Minimally invasive adrenalectomy is the standard of care for the surgical management of benign adrenal disease. The transperitoneal laparoscopic approach (TLA) is the most common approach used worldwide; however, many centres have adopted a posterior retroperitoneoscopic approach (PRA), as it is reported to offer several advantages. We describe our experience with PRA. Methods: We performed a retrospective review of the charts of patients who underwent minimally invasive adrenalectomy via PRA or TLA performed by a single endocrine surgeon between September 2010 and December 2019 at a tertiary academic centre in British Columbia, Canada. Patient and tumour characteristics, operative times and postoperative outcomes were compared between the 2 groups. Results: During the study period, 58 patients underwent adrenalectomy via PRA, and 41 underwent adrenalectomy via TLA. The median American Society of Anesthesiologists score was higher in the TLA group than the PRA group (3.0 v. 2.6, p = 0.02). Adrenal glands were heavier in the TLA group than the PRA group (mean 63.4 g v. 19.2 g, p < 0.001). The mean anesthesia preparation time was shorter with PRA than with TLA (51.5 min v. 63.7 min, p < 0.001), as was mean operative time (77.9 min v. 118.4 min, p < 0.001) and mean hospital length of stay (2 d v. 4 d, p < 0.001). There was no difference in the complication rate between the 2 groups. Conclusion: Our study shows that PRA offers shorter operative time and length of stay for appropriately selected patients. Thus, it has become the preferred approach at our centre for minimally invasive adrenalectomy.
