Bariatric fellowship positively influences early outcomes for laparoscopic Roux-en-Y gastric bypass surgery over seven years of independent practice

Abstract

Introduction Laparoscopic Roux-en-Y gastric bypass (LRYGB) is technically demanding and has an associated learning curve. We published previously that bariatric fellowship reduces the learning curve of primary LRYGB and improves patient outcomes after one year of independent practice. However, the long-term effect of fellowship is unknown. We therefore aimed to compare the 30-day outcomes of LRYGB between the first year of a surgeon's independent practice with the subsequent six years. Materials and methods A prospective database of patients undergoing primary LRYGB under a single surgeon from March 2010 until February 2017 was analysed. Two groups were studied: first year (< 1 year) and the subsequent six years (≥ 1 year) of independent practice. Patient demographics, length of hospital stay, conversion to open surgery, perioperative complications and mortality were compared. Results Among 279 eligible patients, 74 (26.5%) were in the < 1 year group and 205 (73.5%) in ≥ 1 year group. The preoperative risk scores, American Society of Anesthesiologists (ASA) grade, P = 0.00; obesity surgery mortality risk score (OS-MRS), P = 0.04) were significantly higher in ≥ 1 year group. There was no significant difference in perioperative outcomes (length of stay, P = 0.38; total complications, P = 0.20; readmissions, P = 1.00; reoperations, P = 0.60) between the two groups. Conclusions Bariatric fellowship reduces the learning curve for LRYGB and helps to achieve excellent outcomes in the first and subsequent years of independent practice. The higher risk profile of ≥ 1 year group did not equate to an increase in complications, suggesting that experience and standardisation may help in handling complex cases. To our knowledge, this represents the only such study in the literature.

Racial Disparities in Bariatric Surgery Complications and Mortality Using the MBSAQIP Data Registry

“…There are several limitations of this study. While the MBSAQIP data set is the most comprehensive bariatric database available, it is devoid of information that may identify surgeon training level and experience [12,[49][50][51]. Details of patient income level, insurance status, and geographic location are also absent from the dataset, and may provide additional information regarding socioeconomic factors.…”
