Factors that Hinder 24-Hour Discharge After Laparoscopic Roux-en-Y Gastric Bypass: a Retrospective Analysis at a Low-Volume Center.

PURPOSE: This study aimed to identify factors that hinder 24-h patient discharge after laparoscopic Roux-en-Y gastric bypass (LRYGB) in a low-volume practice. MATERIAL AND METHODS: Consecutive patients who fulfilled regional criteria and underwent primary LRYGB from 2018 to 2020 were retrospectively analyzed. Patients were discharged on the morning of the first postoperative day (POD1) after meeting the predefined criteria. The assessed outcome measures (POD1 vital signs, laboratory findings, pain scores and nausea/vomiting) and 30-day postoperative complications were compared between the early (stay ≤ 24 h) and delayed (>24 h) groups. RESULTS: For 107 patients who fulfilled the inclusion criteria, 48 (44.9%) were discharged within 24 h. There were no differences in the baseline demographics, except that the early group was more likely to have a previous abdominal operation (35.4% vs. 16.9%). Both groups had similar operation durations (89 min vs. 92 min), but the early group had a markedly shortened length of stay (23 (24-22) h vs. 27 (47-26) h). The POD1 parameters were the same between the groups, except that the delay group had a significantly higher visual analog scale score, with fewer patient scores of 0. Patients who were younger and female were more likely to need additional IV analgesics. No POD1 antiemesis was required throughout the study. There was no increase in the 30-day complications. CONCLUSION: Patient discharge at 24 h post-LRYGB is feasible and safe in a low-volume practice. A more comprehensive pain relief strategy may be required before generalizing this approach.
