Surgical treatment for septic complications in patients with duodenal perforation following endoscopic retrograde transpapillary interventions

Background. The most severe clinical cases following transpapillary endoscopic interventions are duodenal perforation with damage to the common bile duct and pancreatic duct, entrance into the abdominal cavity and retroperitoneum the aggressive contents of intestine and the infections. They usually lead to higher mortality.Aim. Evaluation of the optimal management for duodenal perforation in patients who have undergone transpapillary endoscopic interventions.Material and methods.A retrospective analysis of surgical treatment in thirty-two patients with duodenal perforation after transpapillary endoscopic interventions from the year 2007 to 2018 in one center was carried out. Nineteen cases (59.4%) were diagnosed less than 24 hours, 13 (40.6%) – more than 24 hours after injury. Twenty patients had the primary reconstruction of duodenum with various drainage options of injury area. In 19 cases there were a two-stage surgical procedure according the original method: 12 had a primary surgery, 7 were reoperated. Results. After primary reconstruction of duodenum 11 patients (55.0%) had complications, seven (63.6%) – were re-operated, in four we have applied efferent treatments and symptomatic therapy. Three patients (15.8%) died. After two-stage surgery procedure 7 patients (36.8%) had surgical complications, five (26.3%) – were re-operated. Three patients (15.8%) – were died.Conclusion. Primary duodenum reconstruction can be performed if the injury occurred less than 24 hours before surgery. Two-staged surgery is justified in cases with purulent inflammation in abdominum and reproperitoneal cavity because procedure allows reducing mortality from abdominal sepsis

Неселективные β-блокаторы в первичной профилактике кровотечений у больных с асцитом, включенных в лист ожидания трансплантации печени

Objective: to determine the efficacy of non-selective beta-blockers (NSBBs) in the primary prevention of bleeding esophageal varices and to assess their impact on the survival of patients with ascites enrolled in the liver transplant waiting list (LTWL).Materials and methods. We carried out a retrospective comparative study of cirrhotic patients with severe ascites and esophageal varices without bleeding before enrollment in the LTWL. Primary prophylaxis of variceal bleeding included the use of NSBBs (n = 97, group 1). These drugs were not used in the other patients (n = 91, group 2).Results. There were no significant differences between the groups in terms of clinical, laboratory and demographic parameters, MELD scores and Child-Turcotte-Pugh (CTP) classes for cirrhosis. Patient groups included in the study had no significant differences with respect to incidence of medium- and large-sized varices and incidence of severe ascites. Bleeding incidence was significantly lower in the NSBBs group than in the non-NSBBs group (52.6% and 95.6%, respectively, p = 0.0001).Conclusion. NSBBs constitute an efficacious therapy in primary prophylaxis of esophageal variceal bleeding, thereby saving life and preventing delisting of patients with ascites from the LTWL.Цель: определение эффективности неселективных β-блокаторов в первичной профилактике пищеводных кровотечений и оценка их влияния на выживаемость пациентов с асцитом, включенных в лист ожидания трансплантации печени.Материалы и методы. Проведено ретроспективное сравнительное исследование пациентов с циррозом печени, с выраженными формами асцита и развитием варикозных узлов пищевода, не имевших эпизодов кровотечений до включения в лист ожидания трансплантации печени. Первичная профилактика кровотечений из варикозных узлов пищевода включала использование неселективных Р-блокаторов (n = 97, первая группа), у других пациентов терапия этими препаратами не проводилась (n = 91, вторая группа).Результаты. Не было отмечено значимых различий между группами по клиническим, лабораторным и демографическим параметрам, показателям MELD и классам цирроза Child— Turcotte-Pugh. Группы пациентов, включенных в исследование, не имели значимых различий в частоте варикозных узлов среднего и большого размера и частоте выраженных форм асцита. Частота развития кровотечений была достоверно ниже в группе пациентов, получавших неселективные β-блокаторы, чем в группе больных без проведения этой терапии (52,6 и 95,6% соответственно, р = 0,0001). Выживаемость пациентов была достоверно выше в группе больных, получавших неселективные Р-блокаторы, чем в группе больных без данной терапии (40,2 и 4,4% соответственно, р = 0,0001).Заключение. Использование в терапии неселективных β-блокаторов является эффективным методом первичной профилактики кровотечений из варикозных узлов пищевода, обеспечивая сохранение жизни и предупреждение выбывания пациентов с асцитом из листа ожидания трансплантации печени

Biliary decompression in patients with obstructive jaundice

Aim. Evaluation of the biliary tract decompression methods and their use results, in patients with obstructive jaundice of various etiologies on the basis of our own clinical material.Material and Methods. A retrospective analysis of the biliary tract drain results in 6935 patients with obstructive jaundice with benign and tumor etiology. In 87% cases there was B Class of obstructive jaundice. In 93% we observed mild (A Class) obstructive jaundice. For the biliary tract drainage we used laparoscopic or open surgical access. The retrograde drain we used in sixty-seven percent cases with obstructive jaundice B Class. In sixty-six percent cases of obstructive jaundice C Class, we used antegrade drain.Results. The biliary decompression was effective in 98%. Regarding the rate and timing of bilirubin reduction, all the applied methods showed a similar result, however, the greatest number of complications and fatalities we recorded in patients after antegrade percutaneous drain of the biliary tract and transabdominal access. In 36% the performed interventions became the final treatment option, and the sixty-one percent of patients underwent two-stage treatment. The overall mortality rate was 3%.Conclusion. The use of percutaneous drainage is justified for obstructive jaundice with tumor origin, and possible radical surgical treatment. Transabdominal access drainage for benign etiology of obstructive jaundice in compensated patients can be safely used. Transduodenal endoscopic drain is an alternative to other methods biliary tract drain in severe and medium obstructive jaundice of benign etiology. The same drain method can be used for drainage of biliary tract in patients with tumors of the hepatopancreatobiliary zone organs, as a palliative treatment

Analysis of four-year management of the waiting list for liver transplantation in Rostov region: prospects for reducing mortality of candidates listed for liver transplantation

Purpose: analysis of various clinical results in patients registered in the liver transplantation waiting list (LTWL).Materials and methods: the study was carried at the Center of Surgery and Donor Coordination of the Rostov Regional Clinical Hospital using clinical, laboratory and instrumental data of 198 patients from the LTWL. 99 men and 99 women were enrolled into this study. The men age ranged from 21 to 70 years (47.8 ± 10.4 years), women age - from 18 to 66 years (49.2 ± 10.9 years). At the time of analysis of the LTWL, the average follow-up period was 14.8 ± 11.2 months. All patients were examined according to the list required for inclusion in the LTWL.Results: depending on the outcome, 198 patients from TLWL were grouped into 4 groups. The first group (delisting group) — 19 patients (9.6 %) with clinical and laboratory indicators that allowed them to be excluded from WL. The second group — 67 patients (33.8 %) who had positive clinical dynamics following therapy. The third group — 39 patients (19.7 %) who underwent liver transplantation. The fourth group — 73 patients (36.9 %) who had negative dynamics following therapy, including patients with a fatal outcome. While keeping LTWL for 4 years, 61 (30.81 %) of 198 listed patients died. The majority (40 patients) died of bleeding from varicose veins and OPPN, 17 patients died of hepatic coma and SPB. Each group represents the distribution of patients according to the MELD-Na scale, the severity of portal hypertension and hepatic encephalopathy.Conclusion: the following factors are indispensable for successful work of the transplant center: systematic work with the territories in order to expand the donor base; defining the patient priority criteria in the LTWL in order to reduce the death rate in the list; detailed examination of the patient before entering the list; forming the observation base; systematic patient observation during the pre- and postoperative period, at the rehabilitation stage, as well as at long-term periods in order to develop an effective algorithm of management of the recipient of a solid organ

WAYS TO PREVENT SUPPURATIVE AND INFLAMMATORY COMPLICATIONS OF ABDOMINAL CAVITY IN PATIENTS WITH CHRONIC PANCREATITIS AT THE ORGAN-PRESERVING PANCREATIC HEAD RESECTION

The aim. of the study was to improve organ-preserving pancreatic head resection in patients with chronic pancreatitis due to application of developed methods that eliminate the pain, common bile duct obstruction, duodenal stenosis, and involvement of major retropancreatic intestinal vessels that prevent the development of inflammatory, infiltrative and septic complications of abdominal cavity. With the use of developed techniques we operated 30 patients. The results of clinical studies and additional tool researches confirmed the effectiveness of methods for addressing the underlying symptoms, clinical manifestations of chronic pancreatitis and prevention of inflammatory, infiltrative and disseminated septic complications of abdominal cavity

Predicting death in patients with end-stage liver disease: a new model for assessing disease severity

Objective. To define possibilities of clinical application of the new original method for estimating failure (death) probability in patients on a liver transplant waiting list.Material and Methods. The study included 350 patients who had been on a liver transplant waiting list for 5 years. Using the comparison of Mann-Whitney test results and evaluation of sensitivity and specificity (ROC curves) it was established that values of age, MELD-Na score, leukocyte level, nature of liver failure and presence of portal vein thrombosis had statistically significant differences between the dead and survived patients (p < 0.05). By means of binary logistic regression, the model assessing the risk of death taking into consideration indicators mentioned above has been obtained. The new index of death probability of a patient on a liver transplant waiting list within one year has been created.Results. Quality evaluation of the created model and the index derived from it showed that the new index had a stronger ability to estimate somatic status severity in a patient with cirrhosis and allowed to make more precise prognosis of adverse outcome risk for not less than 12 months as compared to the standard MELD-Na score. The predicted risk of death coincided with actual mortality of patients in 83% of cases. The EPV criterion was 17.4 what exceeded the minimum admissible threshold of the criterion (10) for small samples and allowed to use the obtained index.Conclusion. The original method allows increasing the accuracy of assessment of failure (death) development in a patient with cirrhosis for one year at any time of its application in the non-invasive way, using the data of the examination standard. In addition, the method helps setting priority in liver transplantation

Использование эндоскопического лигирования варикозных узлов в комбинации с неселективными β-блокаторами, или самостоятельно, в профилактике кровотечений у больных с асцитом, включенных в лист ожидания трансплантации печени

Objective: to conduct a comparative analysis of the effectiveness of two methods – endoscopic band ligation (EBL) alone and in combination with nonselective beta blockers (NSBB) – used for prevention of variceal bleeding (VB); to evaluate their impact on patient survival in severe ascites during long-term stay on the liver transplant waiting list (LTWL). Materials and methods. A retrospective comparative study of two groups of patients with decompensated liver disease, ascites and varices included in the LTWL, who received EBL (n = 41, group 1) and EBL + NSBB (n = 45, group 2). Results. The groups being compared did not differ in demographics, clinical parameters, MELD and Child–Turcotte–Pugh scores. There were no significant differences in the incidence of severe ascites, particularly diuretic-resistant ascites. The study groups did not differ in the incidence of mediumand large-sized varices. Incidence of bleeding did not differ in both groups. Overall mortality was significantly higher in the EBL + NSBB group than in the EBL group. Patient survival was lower, while mortality was higher in the EBL + NSBB group. The combined therapy group had a significantly higher number of acute kidney injury (AKI) than the EBL group. Conclusion. The compared methods are equivalently effective in preventing VB in patients with decompensated cirrhosis with a prolonged stay on the waiting list. Survival rate is significantly lower, while mortality is significantly higher in the EBL + NSBB group than in the EBL group.Цель: проведение сравнительного анализа эффективности двух методов: ЭЛВУ и ЭЛВУ в комбина- ции с НСББ, используемых в целях профилактики кровотечений из ВУ, оценка их влияния на показа- тели выживаемости пациентов с выраженным асцитом в период долгосрочного пребывания в ЛОТП. Материалы и методы. Проведено ретроспективное сравнительное исследование двух групп пациентов с декомпенсированными заболеваниями печени, наличием асцита и ВУ, включенных в ЛОТП, получавших ЭЛВУ (n = 41, первая группа) и комбинацию ЭЛВУ и НСББ (n = 45, вторая группа). Результаты. Сравниваемые группы не различались по демографическим, клиническим параметрам, показателям MELD и классов Child–Turcotte–Pugh. Не было отмечено значимых различий в частоте выраженного асцита, и в частности асцита, резистентного к диуретикам. Исследуемые группы пациентов не различались по частоте варикозных узлов среднего и большого размера. Частота развития кровотечений не различалась в обеих сравниваемых группах. Общая летальность в группе больных, получавших ЭЛВУ + НСББ, была значимо выше, чем в группе ЭЛВУ. Выживаемость пациентов была ниже, а риск развития смертельного исхода – выше у пациентов в группе ЭЛВУ + НСББ. В группе, получавшей комбинированную терапию, обнаруживалось значимо большее количество ОПП, чем в группе, получавшей только эндоскопическое лечение. Заключение. Сравниваемые методы обладают одинаковой эффективностью в предупреждении кровотечений из ВУ у больных с декомпенсированным циррозом при долгосрочном пребывании в листе ожидания. Выживаемость значимо ниже, а летальность значимо выше в группе пациентов, получавших комбинацию ЭЛВУ и НСББ, чем в группе пациентов, подвергшихся только ЭЛВУ
