IBC Oxford University Oral Abstract 45 - Postoperative reduced oral feeding is a risk factor for lengthened period of hospital admission and readmission post bariatric surgery

Abstract Objectives The revolution of the Laparoscopic bariatric techniques and improved postoperative recovery protocols and regimens have reduced hospital admissions, readmissions and stay; some patients continue to have prolonged admission for various reasons. This paper concentrates and explores whether postoperative oral feeding is a potential risk factor for lengthened hospitalization and readmission. Methods A prospective, double blinded, randomized investigation of 450 postoperative patients at King Hussein Hospital, King Hussein Medical City, Amman, Jordan, during the period March 2019–September 2023. Subjects (255 women and 195 men, aged 24–55, with an average of 36 years) were managed for morbid obesity, and were assigned to laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB) groups. Subjects with perioperative hazards and previous bariatric techniques were ruled out. Early oral feeding (oral diet tolerance include solid food and drinking minimum of 1.5 l) with clear fluid on day zero associated with balanced intravenous fluids less than 2.5 l then light hospital diet on the first day after surgery and full hospital diet (solid and fluids) in the second day after surgery were encouraged included subjects with hospital admission (3 days) and group II included subjects with (>3 days) readmission spanned 30days after surgery those are followed the old regimens of reduced oral feedings and full IV fluids from day zero and start clear oral fluids from day one till two weeks post operation (no balanced protocol between IV fluids and when to start clear and solid food time and regimens). Univariate and multivariate logistic regression were used to evaluate effect induced parameters on lengthened hospital admission and readmissions. Results The average period of hospitalization was 3 (2–4) days of hospital admission (HD), more days were recorded in 150/450 (33%) subjects: 90/300 (30%) LSG, and 60/150 (40%) LRYGB (P < 0.005). SO, Reduced postoperative oral feeding, the old regimens, lengthened hospitalization, and increased readmission risk. Readmission incidence was 6% (27/450 readmissions): 16/300 (5%) LSG, and 11/150 (7%) LRYGB (P > 0.05). Conclusion The old feeding protocols and reduced oral feeding is a risk factor for lengthened hospitalization and readmission. And the early feeding with the new feeding protocols decreases hospital stays postop and decrease re admissions.
