Abstrakt: Background: Despite various technical modifications, delayed gastric emptying (DGE) is one of the most common complications after pancreatoduodenectomy. DGE results in longer hospital stay, higher cost, lower quality of life, and delay of adjuvant therapy. We have developed a modified duodenojejunostomy technique to reduce the incidence of DGE. Here we evaluate our 4-year experience with this technique.
Methods: This study evaluated consecutive patients who underwent pylorus-preserving pancreatoduodenectomy using the growth factor technique. It consists of performing a posterior seromuscular running suture with a zigzag stitch that stretches the jejunum and allows future growth of the anastomosis. This results in a longer jejunal opening. The angles at the edge of the duodenum are cut to accommodate the duodenal opening to the longer jejunum (the growth factor). The anterior seromuscular layer is then performed with interrupted sutures to accommodate the larger anastomosis. These patients were compared with a cohort of patients (n = 103) before the introduction of this new technique using propensity score matching.
Results: 134 patients underwent pylorus-preserving pancreatoduodenectomy. Delayed gastric emptying occurred in only three patients (2.2%), one grade B and two grade C. Compared with the 103 patients in the control group with standard technique, the incidence of DGE was significantly higher (11.6%; P = 0.00318). The median hospital stay was also statistically longer in the control group (P = 0.048704). A similar trend was observed in the matched cohort; the proportion of patients who developed DGE was significantly (P = 0.005) lower in the growth factor technique group (2.1% vs. 12.9%). Hospital stay was significantly longer in the standard group (P = 0.008), and patients operated on with the standard technique resumed feeding later than those with the growth factor technique.
Conclusions: This study demonstrated that the new technique of duodenojejunostomy can reduce the incidence and severity of DGE and allow earlier hospital discharge. Comparative studies are still needed to confirm these preliminary results.
