Fast-track laparoscopic bariatric surgery: a systematic review

This study aimed to systematically evaluate the evidence-based literature on fast-track laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic adjustable gastric banding (LAGB) to determine the feasibility and safety of fast-track laparoscopic bariatric surgery. A literature search of PubMed, EMBASE and Cochrane Library using the MeSH terms “bariatric surgery”, “ambulatory surgical procedures” and related terms as keywords was performed. The study included articles that reported on intended next-day discharge for LRYGB and same-day discharge for LAGB. Data were extracted on study design and size, patient demographics, patient-selection criteria, patient preparation, perioperative management, operative details, clinical outcomes, and follow-up. The review included 13 studies classified as level 3b or 4 evidence. There were seven studies that investigated LAGB, five studies investigated LRYGB and one study detailed outcomes from both LRYGB and LAGB. Next-day discharge rate ranged from 81 to 100 % for LRYGB. Same-day discharge rate ranged from 76 to 98 % for LAGB. In LRYGB and LAGB complication, re-admission and mortality rates (≤10.5, ≤7.5, ≤0.1 %, respectively) were comparable with the conventional perioperative care. From our results, the fast-track management of patients undergoing LRYGB and LAGB is feasible. With careful patient selection and preparation within high-volume centres, and application of care pathways including close outpatient follow-up, outcomes for fast-track bariatric procedures can compare favourably with those reported in the literature for standard management, but with decreased cost. However, further studies from independent researchers are required to determine the safety of a generalised adoption of this approach outside of dedicated bariatric units, and to formally demonstrate the cost-benefit of fast-track bariatric surgery.
