Surgical traineeship is essential but must be safe for patients. In thyroid surgery, surgeon volume correlates with improved clinical/economic outcomes. However, it is presently unclear how far does trainee participation affect post‐thyroidectomy complication rates in real‐world and randomized data. We systematically searched four databases for associations of trainee participation with any post‐thyroidectomy outcome. We conducted univariate meta‐analyses, sensitivity analyses, and assessed publication bias qualitatively and quantitatively. We included 1 randomized and 15 observational studies from 3755 records, comprising 34 774 thyroid surgical patients. Trainee participation was associated with 12 min longer operative time, but not higher complication rates (hypoparathyroidism, recurrent laryngeal nerve palsy, hematoma, blood loss, return to operating room, hospitalization duration, readmission, and mortality). Sensitivity, publication bias, and multivariate analyses did not change our findings. Real‐world and limited randomized data suggest that trainee participation in thyroid surgery is safe, given adequate consultant supervision and appropriate case selection.

Background Minimally invasive distal pancreatectomy (MIDP) is being adopted increasingly worldwide. This study aimed to compare the short-term outcomes of patients who underwent MIDP versus open distal pancreatectomy (ODP). Methods A retrospective review of all patients who underwent a DP in our institution between 2005 and 2019 was performed. Propensity score matching based on relevant baseline factors was used to match patients in the ODP and MIDP groups in a 1:1 manner. Outcomes reported include operative duration, blood loss, postoperative length of stay, morbidity, mortality, postoperative pancreatic fistula rates, reoperation and readmission. Results In total, 444 patients were included in this study. Of 122 MIDP patients, 112 (91.8%) could be matched. After matching, the median operating time for MIDP was significantly longer than ODP [260 min (200-346.3) vs 180 (135-232.5), p \ 0.001], while postoperative stay for MIDP was significantly shorter [median 6 days (5-8) versus 7 days (6-9), p = 0.015]. There were no significant differences noted in any of the other outcomes measured. Over time, we observed a decrease in the operation times of MIDP performed at our institution. Conclusion Adoption of MIDP offers advantages over ODP in terms of a shorter postoperative hospital stay, without an increase in morbidity and/or mortality but at the expense of a longer operation time.
