Utility of gastrostomy tube placement at the time of pancreaticoduodenectomy

Purpose: The aim of this study is to investigate the utility of gastrostomy tube (G-tube) placement in reducing delayed gastric emptying (DGE) among patients undergoing pancreaticoduodenectomy (PD).

Methods: We retrospectively reviewed consecutive patients undergoing PD from 2015 to 2020 at our institution. Thirty-day patient outcomes including DGE, length of stay (LOS), reoperation rates, and morbidity were analyzed in patients with or without G-tube placement.

Results: 128 patients with resectable pancreatic head cancer (54 females, median age 68.50 [59.00-74.00]) underwent PD (66 had G-tube placement and 62 did not). There was no significant difference in the incidence of DGE (n = 17 vs. n = 17, p = 0.612), and LOS between the groups. Postoperative ileus (p = 0.007) was significantly lower while atrial fibrillation (p = 0.037) was higher among the G-tube group. Gastrostomy-related complications (p = 0.001) developed in ten patients: skin-related complications (n = 6), tube dislodgement (n = 3) and clogging (n = 1). Nine patients required reoperation during index admission (n = 4 vs. n = 5, p = 1.000). There was no difference in 30-day readmissions (n = 7 vs. n = 5, p = 0.471) and no difference in 30 or 90-day mortality.

Conclusion: Gastrostomy tube placement during index PD did not affect the incidence of DGE. However, patients experienced significant morbidities due to G-tube-related complications. Placement of gastrostomy tubes at the index PD offers no clinical benefits.
