['Even though admission time is reduced with the implementation of various enhanced recovery protocols, many clinics still instruct patients after weight loss surgery to maintain a fluid or minced-food diet for at least 2 weeks postoperatively. We reasoned that with adequate preoperative instructions, including adequate chewing of all foods, early progression to solid foods would not increase the risk of (gastro)enterostomy leakage.', 'In December 2010, a new dietary protocol was implemented for all patients undergoing a Roux-en-Y gastric bypass, allowing progression to solid foods from 12 h postprocedure onwards. All patients received thorough preoperative eating instructions and eating awareness counselling from a qualified dietician and psychologist. A retrospective study was performed of 936 patients who underwent a primary or redo laparoscopic Roux-en-Y gastric bypass between January 2011 and June 2014 in our hospital. All 30-day complications, readmissions and reoperations were noted.', 'No 30-day loss to follow-up occurred. Overall 30-day complication rate was 9.4%, with gastrointestinal leakage occurring in only 0.6%. A low threshold for readmission was maintained due to the short mean admission time of 1.87 days. Readmission rate was 4.8%--mainly for observation of postoperative pain--and 1.8% of our patients required reoperation within 30 days. Mortality was 0.1%. Our results are comparable to results published by other Dutch centres advocating conventional diets, showing no increase in leakage or other complications.'] Does early Postoperative Progression to Solid Foods be Safe After Roux-en-Y Gastric Bypass?
