Should Gastric Decompression be a Routine Procedure in Patients Who Undergo Pylorus-Preserving Pancreatoduodenectomy?

Nasogastric tube placement after abdominal surgery has been a standard procedure for many decades. In pancreatoduodenectomy, delayed gastric emptying (DGE) is still a leading postoperative complication, often resulting in patient anxiety or depression and prolonged hospital stays. Such complications have led many surgeons to prefer postoperative nasogastric decompression because of the greater risk of DGE. Therefore, the goal of this study was to evaluate the DGE and perioperative outcomes after pylorus-preserving pancreatoduodenectomy (PPPD) with or without routine gastrostomy. From May 2009 to December 2014, 228 patients underwent PPPD at the Department of Surgery, Gangnam Severance Hospital, Yonsei University. The first cohort of 116 patients underwent surgery before June 2012 and uniformly underwent gastric decompression as a part of postoperative management. The second cohort of 112 patients underwent operation after July 2012, and gastric decompression was selectively used to facilitate exposure during operation and was removed in the operating room at the end of surgery. We evaluated DGE incidence, time to dietary tolerance, length of hospital stay, and postoperative gastric tube reinsertion rates. Gastric re-decompression was necessary in 38 patients (16.7 %), and there was a significant difference between the two groups (p = 0.006). Eleven (9.8 %) patients in the no-tube gastrostomy group required nasogastric tube reinsertion, and 27 (23.3 %) in the routine gastrostomy group required that the gastrostomy tube be re-drainage. There were no statistically significant differences in the frequency or severity of complications such as delayed gastric emptying or pancreatic leakage. Our study demonstrates that routine postoperative gastric decompression can be safely avoided in patients who undergo PPPD.
