Locally advancement of right colon cancer to the surrounding organs requiring surgical intervention is an extensive proced- ure associated with numerous risks. There are not many cases of which this phenomenon may occur. En bloc pancreatico- duodenectomy and resection of involved viscera should be considered for patients who can appropriately undergo this exhaustive surgery. Our objective is to report the experience we had with this patient who underwent an en bloc pancreati- coduodenectomy and right hemicolectomy and review literature.

DISCUSSION Locally advanced colon cancers to adjacent organs have been a rare phenomenon. However, recently, ~5.2–23.6% of all colorectal cancers, at the time of presentation, penetrate or adhere to adja- cent organs . Even less have been discovered to invade the duodenum and/or pancreas . In previous years, invasion of colorectal cancers were considered unresectable . As research progresses, it has been proven that there has been a decrease in mortality rates with resection of the tumor and involved adja- cent organs . Due to a lack of visualization, local metastatic colorectal cancers are often identiﬁed at the time of surgical Figure 5: Adenocarcinoma of the duodenum – high power. exploration, in which the surgeon may not be completely Downloaded from https://academic.oup.com/jscr/article-abstract/2018/5/rjy100/4999373 by Ed 'DeepDyve' Gillespie user on 21 June 2018 Locally advanced colon cancer resulting in en bloc right hemicolectomy and pancreaticoduodenectomy 3 Figure 6: Adenocarcinoma of the duodenum – low power.

Figure 10: Adenocarcinoma of the head of the pancreas – high power pancreaticoduodenectomy are considerably lower than other methods of treatment. When it comes to surgical intervention, there are three main methods of management of locally invasive colorectal cancers. These include hemicolectomy along with either en bloc pancreaticoduodenectomy, partial duodenectomy with either a pedicled ileal ﬂap repair or direct suture. A 1947 study presented by Calmenson e Black, included a series of eight patients whom had locally advanced colon cancer with duo- denal invasion. These patients agreed to a duodenal resection that resulted in a 0% survival rate after a year (three dying immediately in the post-operative period) . The ﬁrst case of right hemicolectomy with en bloc pancreaticoduodenectomy was described by Van Prohaska in 1953 . Evidence shows that aggressive resection of adjacent organs along with a hemico- lectomy has acceptable morbidity and mortality rates . In comparison, a partial duodenal wall resection was associated with a poor outcome . Even though complete resection Figure 8: Adenocarcinoma of the gallbladder. remains controversial, microscopic examination of locally advanced colorectal cancers have shown to have a direct exten- sion through the serosa of adjacent organs in 53.4%, whereas prepared to resect such a complex spread of cancer.
