Background: With the escalation of surgical treatment of morbid obesity, there is a growing interest in the training of bariatric surgeons. Laparoscopic sleeve gastrectomy (LSG) gained popularity both as a first-stage approach and as a stand-alone procedure.
Objectives: The aim of this study was to assess detectable differences in LSG with intra-operative resident involvement.
Methods: We reviewed obese patients, who had undergone LSG between January 1, 2017 and January 31, 2020. Collected data reported demographic factors, operative time, postoperative complications, and outcomes.
Results: Among 313 patients who met the inclusion criteria, 94 were men and 219 were women. The procedures were performed either by an expert bariatric surgeon (group 1), or a general surgery resident (group 2), respectively in 228 and 85 cases. Mean operative time of the first group was 65.3 ± 18.8 minutes, while it was 74.3 ± 17.2 among trainees (p < 0.001). Perioperative complications were diagnosed in 13 patients (10 in group 1 and 3 in group 2). Mean excess body weight loss after 12 months was 87.7 ± 28.2% in the first group and 81.1 ± 31.6% in the residents group. Between the two groups, we found no differences in the incidence of perioperative complications and in surgical outcomes. Trainee involvement was associated with increased operative time, with no correlation with a worse postoperative course.
Conclusions: Residents can safely perform LSG in referral centers under the supervision of an expert bariatric surgeon. Trainee involvement is not related to increased leak rate, nor to suboptimal short-term outcome.
