Outcomes after combined right hemicolectomy and pancreaticoduodenectomy for locally advanced right-sided colon cancer: a case series

Background: Although right colon cancers mostly grow intraluminally, they may rarely invade neighboring organs without distant organ metastasis. En bloc resection is required for R0 resection in pancreas and duodenum-invasive right colon tumors. Despite the high mortality and morbidity rates, the en bloc right hemicolectomy and pancreaticoduodenectomy (RHPD) procedure can be safely performed in centers experienced in colorectal and hepatobiliary surgery.

Objective: In this study, we aimed to share the results of our patients who underwent en bloc pancreaticoduodenectomy in addition to right hemicolectomy for cases with locally advanced right colon cancer.

Materials and Methods: Patients who were operated on the right colon cancer between January 2010 and March 2018 were retrospectively screened. Patients who underwent RHPD due to locally advanced colon cancer invading the duodenum and pancreas were included in this study. RHPD was performed in cases where radical resection was deemed appropriate, and R0 resection could be performed. Demographic information, intraoperative and postoperative findings, and long-term follow-up data of the patients were recorded.

Results: Six cases underwent RHPD. All of the cases were male, and the mean age was 67 ± 6. Proximal PD was performed in five cases, and total PD was performed in one case. SMV reconstruction was performed in one case with an SMV invasion. One case died due to pneumonia and anastomotic leak in the postoperative period. The other five patients had a mean disease-free survival of 29.2 ± 14.7 months. The 1 and 2-year survival rate was 66.6% and 66.6%, respectively.

Conclusion: RHPD is a surgical operation that can be performed safely in experienced centers with acceptable mortality and morbidity rates in cases suitable for R0 resection.
