Colo-pancreaticoduodenectomy for Locally Advanced Colon Carcinoma- feasibility in patients manifesting as Acute Abdomen

BackgroundFor locally advanced colon carcinoma that invades duodenum and/or pancreatic head is en-bloc right hemicolectomy plus pancreaticoduodenectomy (PD). This procedure may be also named as colo-pancreaticoduodenectomy (cPD). Patients with such carcinoma may abdomen. Emergent PD often leads to high postoperative morbidity and mortality. Here, we aimed to evaluate the feasibility and outcomes of emergent cPD, for patients with advanced colon carcinoma, manifest acute abdomen condition.Patients and MethodsWe retrospectively reviewed of 4,793 patients of colorectal cancer, receiving curative colectomy, during the period from 1993 and 2017. Among them, 30 had locally advanced right colon cancer and had received cPD. Among them, surgery of 11 patients was performed in emergent conditions (bowel obstruction 6, perforation 3, tumor bleeding 2). Selection criteria for emergent cPD were the following: (1) age £60 years, (2) body mass index <35 kg/m2, (3) no poorly-controlled comorbidities, and (4) perforation time ≤6 hours. Three patients did not meet the above criteria received non-emergent cPD after a life-saving diverting ileostomy, followed by cPD, performed three months later. We analyzed these patients in terms of their clinicopathological characteristics, the early and long-term postoperative outcomes, and compared findings between emergent cPD group (e-group, n=11) and non-emergent cPD group (non-e group, n=19). After cPD, staged pancreaticojejunostomy was performed in all e-group, and on 15 of 19 patients in the non-e group. ResultsThe non-e group was older, and had a higher incidence of associated comorbidities, while other clinicopathological characteristics were, similar between the two groups. None of the patients in the two groups succumbed from cPD. Postoperative complication rate was 63.6% in the e-group, and 42.1% in the non-e group (p=0.449). The 5-year overall survival rate was 15.9% in the e-group, and 52.6% in the non-e-group (p=0.192).ConclusionsEmergent cPD is feasible in highly selected patients if performed by experienced surgeons. The early and long-term positive outcomes of emergent cPD are similar to those after non-emergent cPD in patients with acute abdominal conditions.
