THE USE OF ANTEGRADE ENDOBILIARY INTERVENTIONS IN BENIGN DISEASES OF THE BILIARY TRACT COMPLICATED BY MECHANICAL JAUNDICE

Introduction. One of the most common manifestations of diseases of the biliary tract are strictures or stenoses. They can have malignant, inflammatory and traumatic etiology, as well as be accompanied by mechanical jaundice syndrome. Aim. To study the results of the use of antegrade endobiliary interventions in benign diseases of the biliary tract complicated by mechanical jaundice. Materials and methods. An analysis of surgical treatment of 34 patients with benign diseases of the biliary tract complicated by mechanical jaundice (MJ) in the SI “V.T. Zatsev IGUS NAMSU». Choledocholithiasis was the cause of MF in 21 (61.8 %) cases, stricture of the LV in 6 (17.6 %) and stricture of the biliodigestive anastomosis (BDA) in 7 (20.6 %) patients. BDA strictures developed after the following operations: biliobiliostomy — 1 (14.3 %), hepaticojejunostomy — 3 (42.9 %), choledochoduodenoanastomosis — 2 (28.5 %) and hepaticoduodenostomy — 1 (14.3 %) %). Research results. External percutaneous transhepatic cholangiodrainage was performed in 7 (46.7 %) patients, external-internal percutaneous transhepatic cholangiodrainage was performed in 6 (40 %), percutaneous transhepatic cholecystostomy was performed in 2 (13.4 %) patients. With slightly dilated intrahepatic ducts (<5 mm) cholangiodrainage was established in 3 (20 %) patients. Of these, in 3 (20.0 %) cases, a separate percutaneous transhepatic cholangiodrainage of the right and left lobular ducts of the liver was performed. Performing percutaneous transhepatic cholangiography and percutaneous transhepatic cholangiodrainage allows to determine the level and nature of biliary block in a minimally invasive way, to perform biliary decompression and prevention of complications after an unsuccessful attempt at endoscopic treatment. Conclusions. By using antegrade endobiliary interventions, we were able to reduce the risk of biliary decompression complications compared with patients who had unsuccessful attempts at endoscopic treatment from 15 (78.9 %) to 1 (6.67 %), and to reduce the number of complications after reconstructive rehabilitation. operations from 10 (52.6 %) to 1 (6.67 %) and the mortality rate from 2 (10.5 %) to 1 (6.67 %).

Controversial issues of biliary stenting in patients with proximal biliary obstruction

The management of biliary decompression in malignant hilar carcinoma remains controversial. This review shows the most relevant aspects of endoprosthetics for proximal biliary obstruction, including necessity of stenting and morphological verification before radical surgery, selection of approach to drain etc. The main contradictions and ways to solve them are presented in this article, based on evidence researches, international and expert consensus conferences.

Procalcitonin to Predict Severity of Acute Cholangitis and Need for Urgent Biliary Decompression: Systematic Scoping Review

Background: Serum Procalcitonin (PCT) has been reported as a potential biomarker to predict the severity of acute cholangitis (AC) or the need for urgent biliary decompression. This study aimed to identify and summarize the existing research about the serum PCT and the severity of AC, and to find gaps where future studies can be targeted towards. Methods: Following the PRISMA Extension for Scoping Reviews, MEDLINE, EMBASE, and Google Scholar were searched for all peer-reviewed articles with relevant keywords including "cholangitis" and "procalcitonin" from their inception to July 13, 2021. Results: We identified six studies. All the studies employed case-control design and aimed to evaluate the usefulness of serum PCT to predict the severity of AC with key identified outcomes. While potential cut-off values of serum PCT for severe AC ranged from 1.8–3.1 ng/mL, studies used different severity criteria and the definition of urgent biliary decompression. No studies proposed cut-off PCT values for the need for urgent biliary decompression. Conclusion: This scoping review identified that the current level of evidence regarding the usefulness of serum PCT in assessing the severity of AC. Further clinical research is warranted with a focus on standardized outcome measures employing prospective or experimental designs.

Implementation of mini-invasive methods of bile drainage in the treatment of blastomatous mechanical jaundice

Tumor diseases of the BPDZ (biliopancreatoduodenal zone) occupy one of the leading places among the causes of disability and mortality of the population, both according to global and domestic statistics, while in 85–90 % of cases, patients with distal tumor biliary obstruction are detected. The most common symptom of malignant tumors of periampullary localization is OJ(obstructive jaundice), which is found in 86–95 % of patients and becomes the first manifestation of the disease in 65–70 % of cases. Purpose. Optimization of surgical treatment in surgically incurable patients with obstructive blastomatous jaundice. Materials and methods. The study was clinical in nature, it was carried out on the basis of CCH №17 (Kharkov, Ukraine) and the State Institution “Institute of General and Emergency Surgery named after V. I. Zaitsev National Academy of Medical Sciences of Ukraine ") and consisted of two stages. The main task of the first stage was a retrospective assessment of the results of antegrade and retrograde minimally invasive interventions performed in the period from 2006 to 2011 in 122 patients. The main objective of the second stage of the study was to assess the results of surgical treatment of 75 patients with blastomatous breast, who were treated from 2012 to 2019. using the developed treatment algorithm. Results. At the first stage of the study, the effectiveness of endoscopic transpapillary and transhepatic biliary excretion methods in patients with distal malignant obstruction of the gastrointestinal tract was compared, for which patients who underwent minimally invasive interventions were divided into two subgroups: group A (63 observations) biliary excretion, and in group b (59 observations) as biliary decompression antegrade percutaneous-transhepatic methods of drainage of bilious ways were applied. Endoscopic transpapillary surgery showed itself to be, not inferior to open surgery in effectiveness of biliary decompression, instead it has a number of advantages, such as low trauma, relative safety, low complication and mortality. Conclusions. The developed algorithm of bile excretion in incurable patients with blastomatous MF allowed to minimize the number of postoperative complications to 4.0 %, to avoid the development of transient hyperamylasemia and postmanipulation pancreatitis. Endoscopic retrograde methods of RV prosthetics as the final stage of surgical treatment in this category of patients have certain advantages over antegrade methods of external drainage, primarily due to the preservation of the natural passage of bile in the duodenum and better adaptation and tolerability by patients

A new algorithm of preoperative preparation of patients with focal lesions of the biliopancreatic area complicated by mechanical jaundice

Pancreatoduodenal resection (PDR) represents one of the most demanding procedures which is required in patients with a tumoral lesion at this level. The aim of the present article was to report the results of 272 patients submitted to such surgical procedures. All patients were divided into two groups: the main group, for whom the optimized decompression algorithm was used (n=112) and the control group, for whom preparation for PDR was carried out according to generally accepted standards (n=160). Upon admission to the hospital, the total bilirubin level in the main group was 274.6±5.9 µmol/l while in the control group this level was 270.4±4.6 µmol/l. PDR was performed in 272 of the patients. Whipple’s terminolateral anastomosis was performed in 38/160 (23.7%) of patients in the control group; termino-terminal anastomosis according to Shalimov-Kopchak’s method was imposed in 40/160 (25.0%) patients of the control group. Pancreatojejunoanastomosis with the imposition of a ductomucosal anastomosis was performed in 128 patients in total with 73 cases in the main group and in 55 cases in the control one. Pancreatogastroanastomosis with plunging of the pancreatic stump into the stomach stump was performed in 35 patients in total with 19 patients in the main group and 16 in the control group. Pancreatogastroanastomosis with plunging of the pancreatic stump into the ‘stomach sleeve’ was performed in 32 patients in total with 20 patients in the main group and 12 in the control group. The mortality rate in the main group was 6.3% (7 patients), and in the control group, 11.9% (19 patients). In conclusion, biliary decompression may improve the postoperative outcomes after pancreatic resection.

Dynamic change of serum CA19–9 levels in benign and malignant patients with obstructive jaundice after biliary drainage and new correction formulas

Background CA19–9 is one of the most widely used tumor markers in biliary-pancreatic diseases. The measured value may not factually reflect the genuine CA19–9 level secreted by tumor, which affected by biliary obstruction. There is an urgent need of developing a correction formula of CA19–9 in biliary obstructive patients to guide clinical practice and avoid making improper clinical decision. Methods Clinical characteristics were collected among patients undergoing biliary drainage in our hospital between January 2014 and January 2019. By comparing the malignant and benign patients statistically, dynamic change trend of CA19–9 levels after biliary drainage was obtained. The correction formulas of CA19–9 were generated by means of linear regression. Results 121 patients, including 102 malignant and 19 benign patients, were enrolled in this study. The baseline CA19–9 level of malignant patients is much higher than that of benign patients. Total bilirubin (TB) level was found to be not related with CA19–9 value (p = 0.109). The drop proportion of the average CA19–9 level in the malignant patients (39.2%, IQR -18.4-78.6%) was much lower than that in the benign patients (75.7%, IQR 58.1–86.6%) (p = 0.014). The correction formula, CA19–9True = 0.63 × CA19–9Measured - 20.3 (R2 = 0.693, p<0.001), was generated based on the linear relation between CA19–9 after drainage and CA19–9 before drainage in malignant patients, which had similar diagnostic value with true CA19–9 value. Conclusions Quantitative correction formulas of CA19–9 considering the effect of biliary decompression was first proposed in this study, aiming to provide a more accurate CA19–9 level to make more accurate clinical decision and avoid making improper therapeutic schedule.

Application of Damage Control Tactics and Transpapillary Biliary Decompression for Organ-Preserving Surgical Management of Liver Injury in Combat Patient

ABSTRACT The combat penetrating gunshot injury is frequently associated with damage to the liver. Bile leak and external biliary fistula (EBF) are common complications. Biliary decompression is commonly applied for the management of EBF. Also, little is known about the features of combat trauma and its management in ongoing hybrid warfare in East Ukraine. A 23-year-old male was diagnosed with thoracoabdominal penetrating gunshot wound (GSW) by a high-energy multiple metal projectile. Damage control tactics were applied at all four levels of military medical care. Biliary decompression was achieved by endoscopic retrograde cholangiopancreatography (ERCP), endoscopic sphincterotomy (EST) and the placement of biliary stents. Occlusion of the stent was treated by stent replacement, and scheduled ERCP was performed. Partial EBF was diagnosed from the main wound defect of the liver and closed without surgical interventions on the 34th day after the injury. A combination of operative and nonoperative techniques for the management of the combat GSW to the liver is effective along with the application of damage control tactics. A scheduled ERCP application is an effective approach for the management of EBF, and liver resection could be avoided. A successful biliary decompression was achieved by the transpapillary intervention with the installation of stents. Stent occlusion could be diagnosed in the early post-traumatic period, which is effectively managed by scheduled ERCP as well as stent replacement with a large diameter as close as possible to the place of bile leak.

Acute cholangitis in intensive care units: clinical, biological, microbiological spectrum and risk factors for mortality: a multicenter study

Background Little is known on the outcome and risk factors for mortality of patients admitted in Intensive Care units (ICUs) for Acute cholangitis (AC). Methods Retrospective multicenter study included adults admitted in eleven intensive care units for a proven AC from 2005 to 2018. Risk factors for in-hospital mortality were identified using multivariate analysis. Results Overall, 382 patients were included, in-hospital mortality was 29%. SOFA score at admission was 8 [5–11]. Biliary obstruction was mainly related to gallstone (53%) and cancer (22%). Median total bilirubin and PCT were respectively 83 µmol/L [50–147] and 19.1 µg/L [5.3–54.8]. Sixty-three percent of patients (n = 252) had positive blood culture, mainly Gram-negative bacilli (86%) and 14% produced extended spectrum beta lactamase bacteria. At ICU admission, persisting obstruction was frequent (79%) and biliary decompression was performed using therapeutic endoscopic retrograde cholangiopancreatography (76%) and percutaneous transhepatic biliary drainage (21%). Adjusted mortality significantly decreased overtime, adjusted OR for mortality per year was 0.72 [0.54–0.96] (p = 0.02). In a multivariate analysis, factors at admission associated with in-hospital mortality were: SOFA score (OR 1.14 [95% CI 1.05–1.24] by point, p = 0.001), lactate (OR 1.21 [95% CI 1.08–1.36], by 1 mmol/L, p < 0.001), total serum bilirubin (OR 1.26 [95% CI 1.12–1.41], by 50 μmol/L, p < 0.001), obstruction non-related to gallstones (p < 0.05) and AC complications (OR 2.74 [95% CI 1.45–5.17], p = 0.002). Time between ICU admission and biliary decompression > 48 h was associated with in-hospital mortality (adjusted OR 2.73 [95% CI 1.30–6.22], p = 0.02). Conclusions In this large retrospective multicenter study, we found that AC-associated mortality significantly decreased overtime. Severity of organ failure, cause of obstruction and local complications of AC are risk factors for mortality, as well as delayed biliary drainage > 48 h.
