title: Middle-preserving pancreatectomy for advanced transverse colon cancer invading the duodenun and non-functioning endocrine tumor in the pancreatic tail.
abstract: A 73-year-old female was referred to our hospital with a diagnosis of advanced transverse colon cancer with severe anemia and body weight loss. Preoperative evaluations, including colonoscopy, gastroduodenoscopy, and computed tomography, revealed not only a transverse colon cancer massively invading the duodenum, but also a non-functioning endocrine tumor in the pancreatic tail. We performed middle-preserving pancreatectomy (MPP) with right hemicolectomy for these tumors with a curative intent. After the resection, about 6 cm of the body of the pancreas was preserved, and signs of diabetes mellitus have not appeared. The postoperative course was complicated by a grade B pancreatic fistula, but this was successfully treated with conservative management. After a 33-day hospital stay, the patient returned to daily life without signs of pancreatic exocrine insufficiency. Although the long-term follow-up of the patient is indispensable, in this case, MPP might be able to lead to the curative resection of transverse colon cancer massively invading the duodenum and non-functioning endocrine tumor in the pancreatic tail with preservation of pancreatic function.
