Background:
There is controversy regarding which is the best reconstruction technique after the pancreatoduodenectomy. Currently, there are no studies comparing the three most frequent reconstruction techniques: Whipple + Roux-en-Y gastrojejunostomy (WRYGJ), pyloric-preserving + Billroth II (PPBII), and Whipple + BII (WBII).
Methods:
Between 2012 and March 2023, 246 patients underwent pancreaticoduodenectomy with the following type of reconstruction techniques: (1) WRYGJ: 40 patients; (2) PPBII: 118 patients; and (3) WBII: 88 patients. A retrospective comparative study among these groups was performed.
Results:
No significant differences were found among the groups regarding duration of the surgery, the blood volume transfused, or caliber of the Wirsung duct. The size and types of tumors, the degree of differentiation and tumor invasion of the peripancreatic tissue, vascular and neural structures, and lymph nodes were similar among the groups. The rate of R0 resection was lower in WBII (62.5% [55/88]) than in WRYGJ (75% [30/40]) and PPBII (72% [85/118]), but statistically insignificant among the groups (p = 0.232). The incidences of relevant B/C postoperative pancreatic fistula (POPF) were similar among the groups: 7.5% (7/40) in WRYGJ, 17% (20/118) in PPBI, and 26.2% (23/88) in WBII (p = 0.292). In addition, the incidence of B/C delayed gastric emptying (DGE) was higher in WBII (27.3% [24/88]) than in WRYGJ (20% [8/40]) and PPBII (19.5% [23/118]) but statistically insignificance among the groups (p = 0.381). The incidence of medical and surgical complications, intensive care unit and hospital stays, morbimortality at 90 days, and 5-year survival were similar among the groups. Multivariate analysis revealed that POPF grade B/C was a risk factor for DGE grade B/C (odds ratio (OR) = 9.903, 95% confidence interval (CI) = 4.829-20.310; p < 0.001), and a <3-mm Wirsung duct was a risk factor for POPF (OR = 3.604, 95% CI = 1.791-7.254; p < 0.001).
Conclusion:
No technique was superior to the others. Only relevant POPF B/C was a risk factor for DGE B/C, and <3 mm Wirsung for a POPF.
