BACKGROUND: Although intestinal derotation procedure has advantages of facilitating mesopancreas excision during pancreaticoduodenectomy, the wide mobilization takes time and risks injuring other organs. This article describes a modified intestinal derotation procedure in pancreaticoduodenectomy and its clinical impact on short-term outcomes.
METHODS: The modified procedure comprised the pinpoint mobilization of the proximal jejunum following reversed Kocherization. Among 99 consecutive patients who underwent pancreaticoduodenectomy between 2016 and 2022, the short-term outcomes of pancreaticoduodenectomy with the modified procedure were compared with those of conventional pancreaticoduodenectomy. The feasibility of the modified procedure was investigated based on the vascular anatomy of the mesopancreas.
RESULTS: Compared with conventional pancreaticoduodenectomy (n = 55), the modified procedure (n = 44) involved less blood loss and shorter operation time (p < 0.001 and 0.017, respectively). Severe morbidity, clinically relevant postoperative pancreatic fistula, and prolonged hospitalization occurred less often with the modified procedure compared with conventional pancreaticoduodenectomy (p = 0.003, 0.008, and < 0.001, respectively). According to preoperative image findings, most (72%) patients had a single inferior pancreaticoduodenal artery sharing a common trunk with the first jejunal artery. The inferior pancreaticoduodenal vein drained into the jejunal vein in 71% of the patients. The first jejunal vein ran behind the superior mesenteric artery in 77% of the patients.
CONCLUSIONS: By combining our modified intestinal derotation procedure with preoperative recognition of the vascular anatomy of mesopancreas, mesopancreas excision during pancreaticoduodenectomy can be performed safely and accurately.
