Gastropancreatoduodenal resection in the treatment of duodenal cancer in a patient who previously underwent surgery on organs of the hepatoduodenal zone

Duodenal cancer is a rare oncological disease that presents significant difficulties in diagnosis and treatment. This article presents a clinical observation of a 35-year-old man who had previously undergone surgery for a chronic disease of the hepatoduodenal zone. The diagnosis included endoscopic, radiological, and histological methods, which confirmed the presence of a highly differentiated adenocarcinoma of the duodenum with infiltration into the head of the pancreas and the common bile duct. The patient underwent an extended gastropancreatoduodenal resection with lymph node dissection. A histological examination showed no lymphovascular invasion or metastases in the 30 lymph nodes examined. The postoperative period was uncomplicated. No recurrence of the disease was observed during a 5-year follow-up period.
