Pancreatojejunal sutural insufficiency occurring after pancreatoduodenectomy and countermeasures are discussed. In the Department of Surgery at Kurume University School of Medicine, 318 patients underwent pancreatoduodenectomies. The present study includes 15 of these patients, all of whom had pancreatojejunal sutural insufficiency. The frequency of sutural insufficiency was 4.7%. Five patients had bile duct cancer, 5 had cancer of the papilla of Vater, 2 had a carcinoma of the pancreatic head, 1 each had gallbladder cancer, chronic pancreatitis, and papillitis. Six (40%) of the 15 patients died during hospitalization. The presence or absence of sutural insufficiency was confirmed mainly by radiography and determining the properties and amylase levels of the drainage fluid. There was no significant difference due to the method of anastomosis. End-to-side anastomosis had a rate of 5 (5.9%) of 85 patients, while end-to-end had 10 (4.3%) of 233 patients. The sutural insufficiency was manifested as a major leakage in 6 patients and a minor leakage in 9. The degree of lymph node dissection was D0 in 6.1%, D1 in 1.4%, D2 in 4.8% and D3 in 10.8%, with a high incidence of sutural insufficiency in D3 patients. The pancreatic duct diameter was smaller than 4 mm in 10, 5-7 mm in 4 and over 8 mm in 1 patient. The intraoperative pancreatic findings were a soft pancreas in 8, slightly hard in 3, and hard in 4 patients. Fibrosis of the pancreas was normal to slight in 11 and moderate in 4 patients. Drainage by relaparotomy was performed in 4 of the 6 patients with major leakages to control sutural insufficiency, and the other 2 underwent continuous aspiration with an intraperitoneal drain inserted during the operation. The 9 patients with minor leakage underwent conservative treatment including continuous aspiration via an intraperitoneal drain inserted during surgery, fasting, intravenous hyperalimentation, and antibiotic administration. All of the patients with major leakage died from an associated occurrence of hepatic insufficiency, renal insufficiency, intraperitoneal hemorrhage or diffuse peritonitis during hospitalization. However, 8 of the 9 patients with minor leakage had some healing, and the 1 remaining patient developed a pancreatic fistula. The frequency of pancreatojejunal sutural insufficiency was high in patients with minimal pancreatic fibrosis, with soft pancreatic tissue without dilatation of the pancreatic duct, and with relatively good pancreatic function.

Laparoscopy with lesser sac endoscopy (LSE) were used in combination from 1987 to 1992 in 103 patients for differentiation between pancreatic carcinoma and other peripancreatic pathology, staging, and palliation. LSE identified pancreatic carcinoma in 38 patients; pancreatic cystadenocarcinoma in 2 patients; pancreatic cystadenoma in 3 patients; pancreatic adenoma in 1 patient; pancreatic metastases from liver in 2 patients; and pancreatic cysts in 5 patients. False negative diagnosis of pancreatic carcinoma occurred in two cases. Nontumor pancreatic pathology was revealed in 10 patients. Specifically, acute pancreatitis was found in four patients, and chronic pancreatitis was found in six patients. Extrapancreatic cancers were identified in 15 patients: retroperitoneal extraorgan tumors were found in 2 patients; extrahepatic biliary tract cancer in 6 patients; gallbladder cancer in 1 patient; liver cancer in 3 patients; and stomach cancer in 1 patient. In five cases no pathology was found. Overall correct definitive diagnosis was established in 101 patients. Sensitivity of laparoscopy with LSE for pancreatic carcinoma diagnosis proved to be 95 per cent (38 of 40 patients), for pancreatic tumors diagnosis 96.22 per cent (51 of 53 patients); specificity of the method 100 per cent; and accuracy of diagnosis 98 per cent (101 of 103 patients). Thus, the accuracy of the method was as high as the accuracy of combination of all known modalities. Criteria of unresectability were revealed with the combination of LSE and laparoscopy in 75 per cent (30 of 40 cases) of pancreatic carcinoma. Moreover, laparoscopy allowed palliation of pancreatic carcinoma. Laparoscopic cholecystostomy was performed in 10 patients, and laparoscopic cholecystojejunostomy with enteroenterostomy was performed in 6 patients.

Biliopancreatic carcinoma has a poor prognosis since the diagnosis of the tumor occurs late when advanced disease is present. The identification of potential causes and earlier diagnosis are needed to prevent the disease or identify it early enough to improve survival. The main risk factors for pancreatic cancer include advanced age, cigarette smoking, high-fat diet, diabetes mellitus, chronic pancreatitis (especially hereditary pancreatitis) and a positive family history of pancreatic cancer. The most important etiologic factor for the development of gallbladder cancer is gallstone disease. Patients with anatomic abnormalities and chronic inflammatory conditions (primary sclerosing cholangitis, infections with parasites) have an increased incidence of bile duct cancers. Several new and promising imaging techniques have recently become available and our understanding of the mechanisms of carcinogenesis are growing rapidly. However, there is currently no effective screening strategy applicable and it is unknown when to begin screening. For pancreatic cancer, reduction of risk is likely to occur with avoidance of smoking and promotion of healthful diets. Cholecystectomy rates have increased since the introduction of new laparoscopic techniques and will eventually reduce the incidence of gallbladder cancer. Improved imaging techniques, the identification of new genes and a better definition of genetic alterations that characterize preinvasive lesions will hopefully allow to develop sensitive and specific technologies to screen and to detect early biliopancreatic cancer for even premalignant lesions to improve the mostly fatal prognosis if this tumor.

In recent studies a soluble form of human leukocyte antigen class I (sHLA-I) has been found in blood, urine, ascitic fluid, and various other tissues. Research has been focused on the role of sHLA-I in the induction of immunotolerance in organ transplantation. To examine the role of sHLA-I in the immune system of patients with malignancy, we examined serum sHLA-I levels in patients with pancreatic, biliary, hepatic malignancy, and other diseases. We examined sHLA-I levels in the sera of patients with pancreatic cancer (n = 19), benign biliary disease and chronic pancreatitis (n = 20), hepatocellular carcinoma (n = 51), gallbladder cancer (n = 6), cholangiocellular carcinoma (n = 6), and in normal controls (n = 22), using enzyme-linked immunosorbent assay (ELISA). In patients with pancreatic cancer we also analyzed the relationship between sHLA-I and CA19-9, and the specificity and sensitivity of sHLA-I. When patients with acute or chronic hepatitis were excluded from analysis, the mean sHLA-I level in patients with pancreatic cancer was significantly higher than that of normal controls (p < 0.01) and patients with benign disease (p < 0.01), hepatocellular carcinoma (p < 0.01), gallbladder cancer (p < 0.05), and cholangiocarcinoma (p < 0.05). We determined a serum sHLA-I cutoff level for normal controls of 2000 ng/ml; serum levels of sHLA-I were higher than the cutoff in ten patients with pancreatic cancer, and serum levels of CA19-9 were lower than 37 IU/l in 9 of 14 patients; sensitivity and specificity were 88.2% and 85.5%, respectively. Serum levels of sHLA-I in pancreatic cancer patients were higher than in the other diseases, although we found that pancreatic cancer cell lines did not produce the sHLA-I. The evaluation of serum sHLA-I levels could have clinical significance in pancreatic cancer.

The obstructive jaundice is a complex syndrome with both benign etiology (choledocholithiasis, hydatid cyst, chronic pancreatitis) and malignant (cancer of the pancreas, cholangiocarcinoma and gallbladder cancer) and it has a special place in biliopancreatic pathology, with up most importance due to changes in local and general status of the organism, difficult etiologic diagnostic problems for the clinician and whose solution requires teamwork, which involves both the surgeon, gastroenterologist, anesthesiologist etc. The introduction of laparoscopic approach and upper gastrointestinal endoscopy for gallstone disease giving the opportunity to solve choledocholithiasis only by laparoscopic approach or by combining laparoscopic cholecystectomy with extraction of the common bile duct stones using endoscopic retrograde cholangiopancreatography, which greatly restricted the classical surgical indications. In these circumstances, I consider appropriate to review the place and indications of biliodigestive derivations in obstructive jaundice caused by coledocholithiasis.
