Impact of surgical proficiency levels on postoperative morbidity: a single centre analysis of 558 ileostomy reversals

Defunctioning ileostomies reduce the consequences of distal anastomotic leakage following bowel resections. Ileostomy reversal in itself, however, is associated with appreciable morbidity (3–40%) and mortality (0–4%). Despite being a common teaching procedure, there is limited information on the impact of surgical proficiency levels on postoperative outcome.
Adult patients undergoing closure of a defunctioning ileostomy between September 2008 and January 2017 were identified from a surgical administrative database that was collected prospectively (n = 558). Baseline characteristics (age, ASA score, BMI, health care insurance coverage) and closure techniques were recorded. Operation time, rate of bowel resection, postoperative complications ranked by Clavien-Dindo classification and length of stay were analysed with respect to proficiency levels (residents vs. consultants).
Two hundred three ileostomy reversals were performed by residents; 355 ileostomies were closed by consultants. Operation time was considerably shorter in the consultant group (p < 0.001). Major postoperative complication rates however were not different among the groups when adjusted for possible confounders (p = 0.948). The rate of anastomotic leakage was 3% and the overall major morbidity rate was 11%.
Operation time rather than surgical outcome and overall morbidity were affected by surgical proficiency levels. Therefore, ileostomy reversal can be considered an appropriate teaching operation for young general surgery trainees.
