The robotic approach was associated with shorter median operative time (106 vs 119 min; p = 0.002), fewer complications (6% vs 13%; p = 0.018), and fewer conversions to open adrenalectomy (1% vs 4%; p = 0.030), with no difference between the senior and junior surgeons. On adjusted analysis, factors associated with increased operative time were male sex (p < 0.001), BMI > 30 kg/m (p < 0.001), and higher gland weight (p < 0.001). The LC-CUSUM analysis showed proficiency after 8-29 procedures. Compared with the first 10 cases, there was a mean reduction in operative time of 14 min after 10-20 cases, 28 min after 20-30 cases, and 29 min after > 30 cases, regardless of surgeon experience.nnDISCUSSION: With dedicated teams and proctoring, robotic adrenalectomy can be safely adopted at high-volume centers with a minimal LC.},

Most endocrine-related operations were considered elective and safe to postpone, providing a unique opportunity to assess clinical outcomes under protracted treatment plans.
METHODS: American Association of Endocrine Surgeon members were surveyed for participation. A Research Electronic Data Capture survey was developed and distributed to 27 institutions to assess the impact of COVID-19-related delays. The information collected included patient demographics, primary diagnosis, resumption of care, and assessment of disease progression by the surgeon.
RESULTS: Twelve out of 27 institutions completed the survey (44.4%). Of 850 patients, 74.8% (636) were female; median age was 56 (interquartile range, 44-66) years. Forty percent (34) of patients had not been seen since their original surgical appointment was delayed; 86.2% (733) of patients had a delay in care with women more likely to have a delay (87.6% vs 82.2% of men, χ = 3.84, P = .05). Median duration of delay was 70 (interquartile range, 42-118) days. Among patients with a delay in care, primary disease site included thyroid (54.2%), parathyroid (37.2%), adrenal (6.5%), and pancreatic/gastrointestinal neuroendocrine tumors (1.3%). In addition, 4.0% (26) of patients experienced disease progression and 4.1% (24) had a change from the initial operative plan. The duration of delay was not associated with disease progression (P = .96) or a change in operative plan (P = .66).
