Pancreatoduodenectomy associated with colonic resections: indications, pitfalls, and outcomes

Pancreatoduodenectomy (PD) associated with colonic resections (CR) (PD-CR) might be a viable option in case of locally advanced periampullary tumors or right colon cancer. The aim of this review was to reappraise the indications and outcomes of PD-CR focusing on the occurrence of postoperative pancreatic fistula (POPF) and colonic anastomotic leak (CAL). A systematic literature search was performed in Medline and Cochrane Central Register of Controlled Trials (CENTRAL) for studies published between 2000 and 2020 concerning PD-CR for periampullary or colonic neoplasms. Twenty-seven studies were selected. Morbidity after PD-CR ranged from 12 to 65% and surgery-related mortality was approximately 10%. When reported, the rates of POPF and AL were as high as 40% and 33%, respectively. The oncological results were strictly linked to the nature of the primary tumor and did not significantly differ from those achieved with standard resections. Surgical radicality and nodal status resulted the main determinants of outcome for pancreatic and colonic cancer, respectively. Solid evidence about the surgical outcomes of PD-CR is lacking, mainly due to the small proportion of patients undergoing such combined resection. Given the elevated surgical risk, a multidisciplinary evaluation is recommended for patient's selection. The increasing use of neoadjuvant therapies is expected to further change the indications and outcomes of PD-CR in the next future.

Automated summary

The review on PD-CR treatment found a high rate of complications, including pancreatic fistula and colonic anastomotic leak. Surgical radicality and nodal status are crucial determinants of treatment outcomes.
