BACKGROUND: As the incidence of adrenalectomy increases steadily, so does the use of minimally invasive approaches like posterior retroperitoneoscopic adrenalectomy (PRA). To date, the largest studies of PRA have been from abroad, and we sought to provide a contemporary US update on the outcomes after PRA. METHODS: A retrospective chart review was conducted on all PRAs performed at a single tertiary care institution between 2013 and 2020. Patient demographic characteristics, indication for operation, operative details, and postoperative course were abstracted. Outcomes of interest included 30-day mortality, conversion to open or transabdominal approach, postoperative complication, and 30-day readmission. RESULTS: A total of 249 PRAs were performed between 2013 and 2020. The population was 54.2% women and mean (SD) age was 54.1 (14.1) years. Most lesions (60.6%) were left-sided, and the most common diagnosis was nonfunctioning adenoma (39.4%), followed by pheochromocytoma (21.3%) and aldosteronoma (16.6%). Mean (SD) tumor size was 3.2 cm (range 0.5 to 9.4 cm). Median operative length was 110 minutes (range 30 to 319 minutes). Overall, the complication rate was 6.4%. Nine patients (3.6%) had a minor postoperative complication (Clavien-Dindo I to III) and 5 patients (2.0%) had a major postoperative complication (Clavien-Dindo IV to V), including 1 mortality (0.4%). There were 2 conversions of approach (0.8%). The majority of patients (58.2%) were discharged on postoperative day 1, and 92.0% were discharged by postoperative day 3. The 30-day readmission rate was 1.6%. CONCLUSIONS: Current practice demonstrates that PRA is an extremely safe approach, with a complication rate < 7% and mortality rate < 1%. In addition, the vast majority of patients are able to return home in an expedient manner.

Our health system introduced an enteral access clinical pathway (EACP) hoping to increase nutritionist consults and decrease presentation to the Emergency Department, readmission to the hospital, and overall hospital length of stay. We followed patients with short-term access (STA), longterm access (LTA), and short-long-term conversions (SLT) seen in the six months prior to the EACP launch (baseline group) and the six months after (performance group). The baseline cohort consisted of 2,553 patients and the performance cohort of 2,419 patients. Those in the performance group were more likely to receive a nutrition consult (52.4% vs 48.0%, P < .01), less likely to re-present to the ED (31.9% vs 42.6%, P < .001), and less likely to be readmitted to the hospital (31.0% vs 41.6%, P < .001. These findings suggest that the EACP may increase the likelihood of both expert-driven nutritional support and effective discharge planning for hospitalized patients.
