This study aims to compare two feeding approaches after surgery for biliary atresia and choledochal cyst in children. Traditionally, children are kept without oral feeding for more than 48 hours after these operations until bowel activity returns. However, newer Enhanced Recovery After Surgery (ERAS) programs suggest that starting feeding earlier may help children recover faster. In this study, children undergoing surgery for biliary atresia or choledochal cyst will be randomly assigned to one of two groups. One group will start oral liquids within 24 hours after surgery and gradually progress to normal feeding as tolerated (early feeding group). The other group will receive conventional care, where feeding is started after more than 48 hours once bowel activity has returned. Researchers will compare both groups for postoperative complications such as wound infection and anastomotic leakage, as well as the duration of hospital stay. Additional observations will include vomiting, abdominal distension, need for reinsertion of a nasogastric tube, requirement for repeat surgery, and time taken to resume normal feeding. Participation in the study will not affect the standard surgical treatment provided. All children will receive routine perioperative care and will be monitored closely throughout their hospital stay and follow-up visits. The findings of this study may help determine whether early oral feeding is a safe and effective strategy to improve recovery and reduce hospitalization after pediatric hepatobiliary surgery.

Enhanced Recovery After Surgery (ERAS) pathways are evidence-based, multidisciplinary perioperative care protocols designed to reduce surgical stress, maintain physiological function, accelerate recovery, improve patient outcomes, and reduce healthcare costs. Early enteral nutrition is a key component of ERAS programs and has been associated with improved gastrointestinal recovery, reduced postoperative morbidity, and shorter hospital stay across multiple surgical specialties. The role of early oral feeding following pediatric hepatobiliary surgery remains insufficiently studied, particularly in low- and middle-income countries. Biliary atresia and choledochal cysts are among the most common pediatric hepatobiliary disorders requiring major reconstructive surgery. Postoperative feeding practices vary considerably, and many centers continue to delay oral intake until bowel sounds return or passage of stool occurs. However, delayed feeding may prolong recovery, increase dependence on intravenous fluids, and extend hospitalization. This prospective randomized controlled trial will be conducted at the Department of Paediatric Surgery, University of Child Health Sciences and The Children's Hospital Lahore. The study aims to compare early oral feeding with conventional postoperative feeding in children undergoing surgery for biliary atresia and choledochal cyst. A total of 46 eligible patients will be enrolled and randomized equally into two groups. Children aged up to 14 years undergoing elective surgery for Type I or Type IV choledochal cyst and infants up to 3 months of age undergoing surgery for biliary atresia will be considered for inclusion. Patients with preoperative malnutrition, hypoalbuminemia, emergency procedures, external cyst drainage, or those not undergoing portoenterostomy after operative cholangiography will be excluded. All enrolled participants will receive standardized perioperative care. In the intervention group, oral clear liquids will be initiated within 24 hours after surgery and advanced progressively to semisolid and full feeds according to tolerance. In the control group, oral feeding will commence after more than 48 hours postoperatively, following clinical evidence of return of bowel function, including passage of stool or flatus. Patients will be monitored for postoperative complications including anastomotic leakage, surgical site infection, vomiting, abdominal distension, need for nasogastric tube reinsertion, and requirement for reoperation. Discharge criteria will be standardized for both groups and include stable vital signs, adequate oral intake, satisfactory bowel function, and surgeon approval. The primary outcomes will be postoperative hospital stay, anastomotic leakage, and surgical site infection. Secondary outcomes will include time to initiation of feeds, time to full feeding, gastrointestinal tolerance, nasogastric tube reinsertion, postoperative complications, and need for repeat surgical intervention. Data will be analyzed using SPSS version 26. Continuous variables will be reported as mean, median, and standard deviation, while categorical variables will be presented as frequencies and percentages. Comparisons between groups will be performed using independent sample t-tests or Chi-square tests as appropriate, with statistical significance defined as a p-value ≤0.05. This study seeks to generate local evidence regarding the safety and effectiveness of early postoperative feeding following pediatric hepatobiliary surgery. The findings may support implementation of ERAS principles in pediatric surgical practice and contribute to improved recovery, reduced hospitalization, and more efficient utilization of healthcare resources.
