[A case of patient with insulinoma of the pancreas anl infammatory tumor of the sigmoid colon-one-step operation treatment].

: The paper presents the case of a 61 year-old man on with a rare disease--insulinoma of the pancreas. The tumor was discovered accidentally and it displayed no hormonal symptoms. The abdominal pain that the patient had suffered from was probably caused by the inflammatory tumor localized in the sigmoid as the result of diverticulitis. As the patient had no defecation problems, concentration was placed preoperatively on pancreas tumor diagnosis. During the operation the pancreas tumor as well as the sigmoid tumor were resected. Implantation of the whole profile of pancreas tail to the stomach was performed. This method permits for further diagnostics (gastroscopy, ERCP). The man had no diabetes, the blood glucose level was normal. The alimentary tract from the stomach to the duodenum was kept and the pancreas secretory function was acceptable. Colonoscopy in 2002 did not show any pathological changes. One month after the operation the patient suffered from pancreatitis which was localized in the head of the pancreas. Medical treatment relieved all symptoms, but then the cyst in the pancreas head appeared as a sequela. The patient would not agree to its puncture. The inflammatory process in the head of the pancreas may have resulted from surgical treatment, although ERCP showed no passage obstruction between this part of the pancreas and the duodenum. The patient is still on follow-up.
