Duodenum-preserving pancreatic head resection: Long-term results.

Early and late results from 298 patients with chronic pancreatitis who were surgically treated by means of duodenum-preserving pancreatic head resection (DPPHR) were prospectively analyzed. The aim of this operative procedure is to treat complications of chronic pancreatitis caused by inflammatory enlargement of the pancreatic head by decompressing the common bile duct, the pancreatic duct, the duodenum, and the retropancreatic intestinal vessels. End points of the study were early and late postoperative outcome. The follow-up period ranged from 1 to 22 years with a median follow-up of 6 years. In-hospital mortality was 1%, postoperative morbidity was 28.5%, and the rate of repeat laparotomy was 5.7%. Diabetes mellitus developed early in the postoperative period in six patients (2%). After a median follow-up of 6 years, late mortality was 8.9%. In the late follow-up period 88% of our patients were completely free of pain or had infrequent episodes and 63% were able to return to work. DPPHR might be considered as an alternative surgical technique in the treatment of chronic pancreatitis if the dominant lesion is in the pancreatic head.

The clinical relevance of tumor marker CEA, CA 19-9 in regional chemotherapy of hepatic metastases of colorectal carcinoma.

Up to December 1986, 50 patients with documented hepatic metastases from colorectal carcinoma were treated with 5-fluoro-2-deoxyuridine (FUDR) using Infusaid pumps. The response of liver metastases to regional chemotherapy was studied by computerized tomography (CT) and carcino-embryonal antigen (CEA), and/or CA 19-9 antigen serum assays. Preoperative CEA values were pathological in 94% of the patients but only 48% had a pathological concentration of the antigen CA 19-9 of over 37 U/ml. The course of CEA and CA 19-9 in combination with the arterial angio-CT reflected the response of liver metastases to regional chemotherapy. A decrease or normalisation of CEA and CA 19-9 after the beginning of therapy is an indication of partial or complete remission of metastases (68% of the patients showed lowered CEA serum values). If the marker continues to rise in serum this is a danger signal of progression of liver metastases or of extrahepatic tumor spread if the tumor stage in the liver remains unchanged.

Total drainage of the right lung into the right hepatic vein.

Report of a case oa anomalous venous drainage of the right lung into the right hepatic vein treated by disconnection of the anomalous pulmonary vein and end-to-side anastomosis to the left atrium. Following a review of 25 surgically treated patients with infracardiac drainage of the right lung the different surgical approaches are discussed.
