A comparative study of postoperative outcomes after stapled versus handsewn gastrojejunal anastomosis for pylorus-resecting pancreaticoduodenectomy.

BACKGROUNDS/AIMS: A stapler is widely used in various surgeries, and there have been recent attempts to use it for performing duodenojejunostomy and gastrojejunostomy during pancreaticoduodenectomy. This study aimed to compare the postoperative results of handsewn gastrojejunostomy (HGJ) and stapled gastrojejunstomy (SGJ) limited to pylorus-resecting pancreaticoduodenectomy (PrPD) performed by a single surgeon.

METHODS

This retrospective study was conducted between January 2014 and March 2020, and included 131 patients who underwent PrPD performed by a single surgeon. Of the total subjects, 90 were in the HGJ group and 41 in the SGJ group.

RESULTS

The mean time of surgery was significantly shorter in the stapled group than in the handsewn group (450.4±75.4 min vs. 397.1±66.5 min, p<0.001). However, there were no significant differences between the groups in the rates of postoperative pancreatic fistula, bile leak, chyle leak, intra-abdominal fluid collection, postoperative bleeding, ileus, Clavien-Dindo, rate of reoperation, and 30-day mortality, including delayed gastric emptying (DGE) (n=11 vs. n=6, p=0.92).

CONCLUSIONS

Gastrojejunostomy using a stapler in PrPD reduces the reconstruction time without any increase in the rate of complications, including DGE. Therefore, using a stapler for gastrojejunostomy in pancreaticoduodenectomy is feasible and safe.
