Observation of two-neutrino double-beta decay in 136Xe with the EXO-200 detector.

We report the observation of two-neutrino double-beta decay in (136)Xe with T(1/2) = 2.11 ± 0.04(stat) ± 0.21(syst) × 10(21) yr. This second-order process, predicted by the standard model, has been observed for several nuclei but not for (136)Xe. The observed decay rate provides new input to matrix element calculations and to the search for the more interesting neutrinoless double-beta decay, the most sensitive probe for the existence of Majorana particles and the measurement of the neutrino mass scale.

[Pancreatic pseudocysts in recurrent pancreatitis: traditional and mini-invasive surgery/endotherapy. Problems in the treatment strategy choice].

Introduction of methods of miniinvasive surgery/endotherapy have permitted to widen essentially the possibilities of treatment of complicated recurrent pancreatitis. Miniinvasive interventions on pancreatic gland and neighbor organs, as well as laparotomic interventions, must be regarded not as an alternative, but like interchangeable methods, permitting to improve significantly the treatment outcome in an acute destructive and chronic pancreatitis, including those, which is complicated by a pancreatic pseudocysts formation.

[Recurrent pancreatitis as a surgical problem]. / Retsidiviruiushchii pankreatit kak khirurgicheskaia problema.

Experience in the treatment of 1498 patients with alcoholic pancreatitis treated with laparotomic and mini-invasive surgeries both in acute and chronic phases of the disease is presented. In 742 patients surgical treatment was multistaged. Re-operations in 17 patients with "chronic purulent pancreatitis", reconstructive surgeries on the pancreas, pancreatic and bile ducts in 84 patients with "head" pancreatitis were most difficult. Percutaneous puncture-catheter procedures for liquid formations in acute phase of pancreatitis were effective as the first stage of treatment to reduce the danger of subsequent laparotomy. Catheterisation of chronic pseudocysts in alcoholic pancreatitis is associated with frequent complications and recurrences and can not be regarded as alternative to internal drainage surgeries. Pancreatic surgeries must guarantee effective correction of intrapancreatic hypertension for prevention of acute pancreatitis recurrences. In acute phase of pancreatitis surgical methods must ensure prevention of symptoms recurrences and pyoseptic complications of pancreatitis.

[Assessment of pancreatoduodenal resection completion methods]. / Otsenka metodov zaversheniia pankreatoduodenal'noi rezektsii.

The nearest outcomes of 305 pancreatoduodenal resections (PDR) for malignant and benign diseases of the pancreas head and periampullar zone are presented. Necessity of differential approach to choice of method of pancreatodigestive anastomosis formation is demonstrated. In unectatic main duct of the pancreas and unchanged pancreatic parenchyma there is a high risk of postoperative pancreatitis and lethal outcome which achieved 29.8% in the group of 57 patients. In patients with diameter of main pancreatic duct more than 3 mm and fibrotic changes of its parenchyma, the majority of methods of pancreas inclusion the in digestive canal were characterized by favorable results, lethality was 7.7% among 248 patients. Recently, the increase of rate of PDR with pylorus preservation permits to apply widely pancreato-, bilio-, and duodenoenteroanastomosis on the same jejunal loop.

[Carbohydrate metabolism in patients after pancreatoduodenal resection]. / Sostoianie uglevodnogo obmena u bolnykh posle pankreatoduodenalnoi rezektsii.

The authors studied carbohydrate metabolism 4 weeks to 12 months after pancreatoduodenal resection (PDR) in 21 patients whose ages ranged from 40 to 55 years. Seven of them had been operated on for carcinoma of the major duodenal papillas and the other patients for carcinoma of the major duodenal papillas and the other patients for carcinoma of tree pancreas. The control group was formed of 10 healthy volunteers of the same age as the patients of the two groups under study; 10 patients who were subjected to PDR with pancreatojejunostomy and 11 patients in whom resection of the pancreatic stump was completed by intraductal occlusion of the formed stump. None of them had disorders of carbohydrate metabolism before the operation. The patients were examined by the oral test for glucose tolerance (OTGT, 75 g of glucose) with glycemia determination and by intravenous glucose tolerance test (i.v. GTT) with determination of glycemia and C-peptide. It was found that the glycemia curves obtained during OTGT did not have a diabetic character according to the WHO criteria. In performing TTG, the coefficient K was diabetic in both groups. Study of the C-peptide level during the i.v. GTT showed that in the group with occluded ducts the level of the C-peptide and the nature of its secretion differed obviously from those in the other groups under study, which testified to disturbances in the homeostai mechanisms.

[Results of transduodenal papillosphincterotomy and double internal drainage of the common bile duct using the SPP-20 device]. / Rezultaty transduodenalnoi papillosfinkteroplastiki i dvoinogo vnutrennego drenirovaniia obshchego zhelchnogo protoka, vypolnennykh apparatom SPP-20.

The authors discuss the immediate and late results of operations conducted with the [symbol: see text] suturing instrument of their design. It made possible one-stage transduodenal papillosphincteroplasty by application of two rows of tantalum staple sutures with division of the tissue between them--papillosphincterotomy. The authors conducted the operation on 242 patients for benign stenosis of the common bile duct by stones incarcerated in it. In 29 patients the intervention was complemented by the formation of supraduodenal choledochoduodenoanastomosis by means of the same suturing instrument, establishing in this was double internal drainage of the bile ducts. The suturing instrument made the operation easier and atraumatic and provided reliable hemostasis. Immediate postoperative mortality as 1.9%. Transduodenal papillosphincterotomy with the [symbol: see text] suturing instrument produced g od and satisfactory results in 95.2% and poor results in 4.8% of patients; poor late results of double drainage of the choledochus by the authors' method were not registered.

[Choice of bile-diverting operations in neoplastic obstruction of the distal common bile duct]. / Vybor zhelcheotvodiashchikh operatsii pri opukholevoi neprokhodimosti distal'nogo otdela obshchego zhelchnogo protoka]

Analysis of clinical material of 206 patients with tumor obstruction of the distal part of the common bile duct allowed the conclusion to be made on the expediency of applying endoscopic methods for jaundice correction as the first stage in preparation for the operation (122 patients) and also as the only and final operation (70 patients). Study of the immediate and late-term results of different variants of operations for bile diversion in obstruction of the distal choledochus (203 operations) showed the superiority of the Roux hepaticoejunoanastomosis in which recurrent jaundice due to obstruction of the cystic duct does not occur, as is encountered in creation of a cholecystoejunoanastomosis, and there are no conditions for the development of ascending cholangitis.

[Problems in the surgical treatment of pancreatic chronic diseases]. / Problemy khirurgii khronicheskikh zabolevanii podzheludochnoi zhelezy.

The work analyses the results of 999 operations on the pancreas conducted in 861 patients with chronic oncological and nonneoplastic diseases of the gland. Pancreatoduodenal resection (PDR) was performed in 171 patients (for tumors of the pancreaticoduodenal zone in 151 and for chronic pancreatitis of the head of the gland in 20) in 13 of them a modified operation with preservation of the stomach and pylorus was carried out. The late-term results were satisfactory in both groups of patients, the survival of oncological patients was much higher after radical operations then after palliative surgery. Total duodenopancreatectomy has no advantages over PDR and should be undertaken only when there are strict indications. In chronic pancreatitis, complicated also, preference was given to organ-preserving interventions, primarily to draining operations, which preserve more fully pancreatic exocrine and endocrine functions: longitudinal pancreatojejunostomy was conducted in 106 patients, internal drainage of pancreatic cysts in 184, and occlusion of external pancreatic cysts in 70 patients. It is advisable that the most complicated, particularly repeated and reconstructive, operations on the pancreas are carried out at specialized centers in which the problem of surgical diseases of the pancreas is studied more closely.

[Surgical treatment of patients with chronic calculous pancreatitis]. / Khirurgicheskoe lechenie bol'nykh khronicheskim kal'kuleznym pankreatitom.

The article discusses experience in the examination of 109 patients with chronic calculous pancreatitis (CCP), 102 of them were treated by operation (a total of 130 operations were carried out). Calculous cholecystitis was a consequence of alcohol intake in 102 cases, and was due to other causes in 7 cases. In 71% of cases CCP was attended by the development of indirect signs of pancreatic hypertension and in 45.1% by pancreatic cysts. Operations for internal (h = 49) and external-internal (n = 27) drainage were most pathogenetically justified. The mortality after these operations was 2%. The total postoperative mortality was 6.9%, mortality in the late-term periods was 8.8%. Unfavourable late-term results were encountered in individuals who continued drinking alcohol as well as in inadequate drainage of the pancreatic duct system.

[A method of pancreato-duodenal resection and total duodeno- pancreatectomy]. / Metodika pankreatoduodenal'noi rezektsii i total'noi duodeno- pankreatéktomii.

During 1975-88 the staff of the Vishnevskii+ Institute of Surgery performed 95 pancreatoduodenal resections (PDR) and 23 total duodenopancreatectomies (TDPE) in malignant tumors of the head of the pancreas (49), major duodenal papilla (30), terminal choledochus (12), duodenum (12), and in 15 patients with chronic pancreatitis. In 13 cases PDR and TDPE were undertaken as a second operation after creation of biliodigestive anastomoses: after laparoscopic cholecystostomy in 24 and after various abdominal operations in 20 cases. In 30 cases PDR was carried out with the formation of a pancreaticojejunal+ anastomosis, by the longitudinal techniques in 7 of them, in 47 cases with occlusion of the pancreatic duct, and in 6 with the formation of a "occlusive" pancreaticojejunal anastomosis++ suggested by the authors. PDR was performed in 3 cases with maintenance of the stomach and in 4 in combination with vagotomy. The mortality rate was 20% after PDR and 39.1% after TDPE.

[Nervous and mental disorders in patients with chronic alcoholic pancreatitis]. / Nervno-psikhicheskie rasstroistva u bol'nykh khronicheskim pankreatitom alkogol'noi étiologii.

Presented are the results of comprehensive CNS examinations in 53 alcoholics with chronic pancreatitis. Related psychopathological and neurological syndromes are specified. Hepatopancreatoduodenal and CNS abnormalities were found directly correlated. The addition of pancreatitis to alcoholism leads to development of encephalomyelopolyradiculoneurotic syndrome.

[Surgical treatment procedures in patients with external and internal hepatobiliary fistulae]. / Taktika khirurgicheskogo lecheniia bol'nykh s naruzhnymi i vnutrennimi pechenochno-zhelchnymi svishchami.

Within a period of from 1967 to 1987, the authors treated 389 patients with injuries and diseases of the liver, bile ducts, adjacent organs, which were complicated by long-existing external and internal fistulas of the bile ducts, or intrahepatic cavities.

[Ultrasonic endoscopic examination in pancreatic diseases]. / Ul'trazvukovoe éndoskopicheskoe issledovanie pri zabolevaniiakh podzheludochnoi zhelezy.

Under analysis were 76 patients with diseases of the pancreas. The data of the ultrasonic endoscopic method were compared with operative findings in 49 patients and with the final clinical diagnosis in 27 non-operated patients. The correctness of the method in the group of operated patients was 80%, in non-operated patients 96.3%.

[Occlusive pancreatojejunoanastomosis in pancreatoduodenal resection]. / Okkliuzionnyi pankreatoeiunoanastomoz pri pankteatoduodena'lnoi rezektsii.

A technique for creation of occlusive pancreatojejunoanastomosis (OPJA) in pancreatoduodenal resection was used in 7 patients. Uncomplicated course of the postoperative period was noted in 6 of them. The indications for formation of the OPJA are substantiated by the experience with 32 pancreatoduodenal resections with pancreatojejunoanastomosis formation, and 47--with occlusion of the pancreatic stump.
