Delayed Gastric Emptying After Pancreatoduodenectomy: Pyloric Ring Resection vs Classical Whipple's

During his super-specialty MCh training at SVIMS Tirupati (2019-2022), Dr. Sudish Durgesh conducted an extensive prospective comparative clinical trial evaluating delayed gastric emptying (DGE) outcomes following Pyloric Ring Resection Whipple's versus the Classical Whipple's Procedure. DGE is characterized by prolonged nasogastric decompression and inability to tolerate oral nutrition. By systematically resecting the muscular pyloric ring while preserving gastric reservoir capacity, the incidence of Grade B and C delayed gastric emptying was significantly attenuated, allowing earlier enteral feeding and accelerated recovery. Methods & Clinical Evaluation: The study prospectively randomized patients undergoing pancreatoduodenectomy for resectable periampullary and pancreatic head tumors. Gastric decompression duration, time to first liquid sips, tolerance of solid diet, and postoperative complications were meticulously monitored according to the International Study Group of Pancreatic Surgery (ISGPS) consensus definitions. Key Findings & Academic Impact: The cohort receiving Pyloric Ring Resection demonstrated significantly shorter time to solid oral intake (median Day 4 vs Day 8) and a remarkable reduction in clinically relevant Grade C DGE. This surgical refinement contributes directly to faster rehabilitation and lower inpatient hospitalization costs.
