Empiric nasogastric decompression after pancreaticoduodenectomy is not necessary

Abstract

Background: The aim of the present study was to evaluate the impact of routine NGT decompression after PD on postoperative outcomes in the era of an enhanced recovery after surgery (ERAS) protocol.

Materials and methods: A retrospective review of all patients undergoing PD between January 2015 and October 2017 at our institution was performed comparing routine post-operative NGT decompression versus omission. The incidence of delayed gastric emptying, post-operative pancreatic fistula, hospital length of stay, operative time, 30-day readmission rate as well the time to first oral intake were evaluated.

Results: Out of 149 patients who underwent PD, 65 maintained post-operative NGT decompression while post-operative NGT decompression was omitted in 84 patients. No differences were noted in delayed gastric emptying rates (both p>0.05). The median length of stay (9 days for NGT group versus 8.5 days for no NGT group) and 30-day readmission rates (13.8% versus 15.5%, respectively) were similar (p=0.781). Compared with patients who had routine post-operative NGT placed, those who had omission of a post-operative NGT had a lower need for reinsertion, shorter time to PO intake, and a lower likelihood of extended length of stay.

Conclusions: In the era of ERAS protocols, we observed no association between routine post-operative NGT decompression after PD and improved postoperative outcomes.
