Correlation between functional drainage and survival in malignant biliary obstruction after percutaneous biliary drainage

PurposeMalignant biliary obstruction (MBO) is common in patients with advanced malignant tumors, leading to poor prognosis and hindering antitumor therapy. The purpose of our study was to assess the survival outcomes for patients under therapy after percutaneous transhepatic biliary drainage (PTBD) and identify prognostic factors associated with survival in patients with MBO. MethodsFrom July 2010 to February 2021, 269 patients with MBO secondary to malignant tumor were divided into two groups (functional success and non-functional success). Survival time and prognostic factors were analyzed by Kaplan–Meier curves and the Cox model. ResultsThe overall median survival time after PTBD was 4.6 months (95 % IC:3.9–5.3). The 3- and 6-month survival rates were 68.0 % and 38.7 %, respectively. The median survival improved from 3.2 months to 8.4 months when the procedure achieved functional success. Multivariate analysis demonstrated that functionally successful drainage and antitumor treatment after PTBD were independent positive prognostic factors, but the total bilirubin after drainage and tumor size were independent negative predictive values. ConclusionsFunctionally successful drainage could prolong survival time in patients with malignant biliary obstruction. Palliative care after drainage can prolong patient survival and improve their quality of life.

Surgical treatment and prognostic factors in perihilar tumors

To study the results of surgical treatment in patients with perihilar tumors. We analyzed 98 patients with perihilar tumors who underwent surgery. We prefer percutaneous transhepatic biliary drainage (n=58) for jaundice. Retrograde interventions were performed in 18 cases (20.5%), complications grade III-IV were more common (p=0.037) in the last group. Postoperative mortality was 12%. Complications developed in 81 patients (82.7%), grade ≥3 - in 39 (39.8%) cases. Portal vein resection (n=26) increased the incidence of complications grade ≥III (p=0.035) and portal vein thrombosis (p=0.0001). Chemotherapy after surgery was performed in 47 patients (48.0%), photodynamic therapy - in 7 (7.1%) patients. A 5-year overall survival was 28.1%, the median survival - 29 months. R2 resection and/or M1 stage (n=12) significantly worsened the prognosis and overall survival (16.5 vs. 31 months, p=0.0055). Lymph node (LN) lesion, microscopic status (R0 vs. R1) of resection margin, technique of decompression and isolated resection of extrahepatic bile ducts did not affect the prognosis, and we combined appropriate patients (n=72) for analysis. SI resection and excision of ≥6 lymph nodes were independent positive factors for disease-free survival (p=0.042 and p=0.007, respectively). Blood transfusion and high preoperative neutrophil-lymphocyte index (NLI ≥2.15) worsened overall (p=0.009 and p=0.002, respectively) and disease-free survival (p=0.002 and 0.007, respectively). The absence of adjuvant therapy worsened disease-free survival alone (p=0.024). SI liver resection, adequate lymph node dissection and adjuvant therapy should be used for perihilar tumors. Isolated resection of extrahepatic bile ducts is permissible in some cases. Blood transfusion and NLI ≥2.15 are independent negative prognostic factors.

Safety and feasibility of laparoscopic radical resection for bismuth types III and IV hilar cholangiocarcinoma: a single-center experience from China.

Surgery represents the only cure for hilar cholangiocarcinoma (HC). However, laparoscopic radical resection remains technically challenging owing to the complex anatomy and reconstruction required during surgery. Therefore, reports on laparoscopic surgery (LS) for HC, especially for types III and IV, are limited. This study aimed to evaluate the safety and feasibility of laparoscopic radical surgery for Bismuth types III and IV HC. The data of 16 patients who underwent LS and 9 who underwent open surgery (OS) for Bismuth types III and IV HC at Mianyang Central Hospital, School of Medicine, University of Electronic Science and Technology of China, between December 2017 and January 2022 were analyzed. Basic patient information, Bismuth-Corlette type, AJCC staging, postoperative complications, pathological findings, and follow-up results were evaluated. Sixteen patients underwent LS and 9 underwent OS for HC. According to the preoperative imaging data, there were four cases of Bismuth type IIIa, eight of type IIIb, and four of type IV in the LS group and two of type IIIa, four of type IIIb, and three of type IV in the OS group (P>0.05). There were no significant differences in age, sex, ASA score, comorbidity, preoperative percutaneous transhepatic biliary drainage rate, history of abdominal surgery, or preoperative laboratory tests between the two groups (P>0.05). Although the mean operative time and mean intraoperative blood loss were higher in the LS group than in OS group, the differences were not statistically significant (P=0.121 and P=0.115, respectively). Four patients (25%) in the LS group and two (22.2%) in the OS group experienced postoperative complications (P>0.05). No significant differences were observed in other surgical outcomes and pathologic findings between the two groups. Regarding the tumor recurrence rate, there was no difference between the groups (P>0.05) during the follow-up period (23.9 ± 13.3 months vs. 17.8 ± 12.3 months, P=0.240). Laparoscopic radical resection of Bismuth types III and IV HC remains challenging, and extremely delicate surgical skills are required when performing extended hemihepatectomy followed by complex bilioenteric reconstructions. However, this procedure is generally safe and feasible for hepatobiliary surgeons with extensive laparoscopy experience.

Endoscopic Treatment of Malignant Hilar Biliary Obstruction.

Stent implantation is an effective approach for palliative treatment of Bismuth-Corlette type III-IV malignant hilar biliary obstructions (MHBOs). In this article, we reviewed the currently used access methods for biliary stent placement (percutaneous transhepatic biliary drainage, endoscopic biliary drainage, endosonography guided biliary drainage), the available stent types (plastic stent, self-expanding metallic stent, full cover self-expanding metallic stent, radioactive self-expanding metallic stent), major approaches (unilateral, bilateral) and deployment methods (stent-in-stent, stent-by-stent). Finally, this review gives an outlook on perspectives of development in stenting and other palliative methods in MHBO.

Biliary drainage in hilar and perihilar cholangiocarcinoma: 25-year experience at a tertiary cancer center

This study analyzed the optimal biliary stenting strategy for palliation in cholangiocarcinoma (CCA). This was a retrospective study of patients with CCA who underwent biliary drainage from 1997 to 2023. A per-patient analysis of percutaneous transhepatic biliary drainage (PTBD) rates, the median number of ERCPs, and overall survival (OS) and a per-procedure analysis of clinical success (CS), stent-specific adverse events (AEs), and mean time to repeat ERCP by stent type and laterality (unilateral and bilateral) are presented. A total of 333 patients underwent 1050 ERCPs, 85% with plastic stents (PSs). PTBD was eventually done in 23% of PS patients, 35% of whom had their PS removed before PTBD. ERCPs with the use of self-expandable metal stents (SEMSs)/unilateral SEMSs had higher CS (89%/91%) versus PSs/unilateral plastic stents (uPSs) (85% both) and PSs within SEMSs (PS-SEMSs)/uPS-SEMSs (71%/74%; P= .013/P= .054). Compared with PSs, SEMSs and PS-SEMSs were associated with higher stent-specific AEs (odds ratios [ORs]: SEMSs 4.85 [95% confidence interval (CI), 3.23-7.27], PS-SEMSs 9.99 [95% CI, 5.33-18.71]; P< .001). Straight PSs were associated with more stent-specific AEs compared with double-pigtail stents (OR 6.74 [95% CI, 3.95-11.45]; P< .001). More 7F stents were used in cases with balloon dilation (BD) (109 with BD vs 88 without BD; P< .001). BD had a 79% CS rate versus 87% without BD (P< .001). Cases with pus on ERCP and those with BD had a shorter mean time to repeat ERCP. On regression analyses, higher Bismuth class, PS use, and PS-SEMS use were associated with a shorter mean time to repeat ERCP. Fifty-two percent of patients in the bilateral SEMS arm died from cholangitis (P= .005). The relatively higher CS rate of SEMSs is countered by the higher stent-specific AE rate. PSs can be removed and may better facilitate PTBD. Within PS types, double-pigtail stents may have fewer stent-specific AEs. Cases requiring BD and with endoscopic evidence of pus may benefit from earlier reintervention.

Endoscopic Biliary Drainage in Surgically Altered Anatomy.

Endoscopic retrograde cholangiopancreatography (ERCP) is considered the preferred method for managing biliary obstructions. However, the prevalence of surgically modified anatomies often poses challenges, making the standard side-viewing duodenoscope unable to reach the papilla in most cases. The increasing instances of surgically altered anatomies (SAAs) result from higher rates of bariatric procedures and surgical interventions for pancreatic malignancies. Conventional ERCP with a side-viewing endoscope remains effective when there is continuity between the stomach and duodenum. Nonetheless, percutaneous transhepatic biliary drainage (PTBD) or surgery has historically been used as an alternative for biliary drainage in malignant or benign conditions. The evolving landscape has seen various endoscopic approaches tailored to anatomical variations. Innovative methodologies such as cap-assisted forward-viewing endoscopy and enteroscopy have enabled the performance of ERCP. Despite their utilization, procedural complexities, prolonged durations, and accessibility challenges have emerged. As a result, there is a growing interest in novel enteroscopy and endoscopic ultrasound (EUS) techniques to ensure the overall success of endoscopic biliary drainage. Notably, EUS has revolutionized this domain, particularly through several techniques detailed in the review. The rendezvous approach has been pivotal in this field. The antegrade approach, involving biliary tree puncturing, allows for the validation and treatment of strictures in an antegrade fashion. The EUS-transmural approach involves connecting a tract of the biliary system with the GI tract lumen. Moreover, the EUS-directed transgastric ERCP (EDGE) procedure, combining EUS and ERCP, presents a promising solution after gastric bypass. These advancements hold promise for expanding the horizons of comprehensive and successful biliary drainage interventions, laying the groundwork for further advancements in endoscopic procedures.

High Output External Biliary Drainage Leading to Acute Kidney Injury in a Patient with Malignant Obstructive Jaundice: A Rare Case Report

Most patients with malignant obstructive jaundice present to the hospital in an advanced unresectable stage. Percutaneous transhepatic biliary drainage (PTBD) and stenting are the established , safe and effective way of palliative treatment aiming prolongation and improving the quality of the life. We report a rare case of high output external biliary drainage leading to AKI and electrolyte imbalance following insertion of PTB drain. Patient was managed with hemodialysis and subsequent self- expandable metallic stent (SEMS) placement. We highlight the importance of awareness of this complication and need of further studies regarding role of biliary interventions, associated complications and management.

Perceptions of transitional care services among patients with percutaneous transhepatic biliary drainage and multicentre health professionals: A qualitative study.

Patients with percutaneous transhepatic biliary drainage (PTBD) need regular drainage tube care after discharge, and transitional care can help solve this problem. However, few studies have focused on the quality of transitional care, the perceptions of patients with drainage tubes after discharge and those of healthcare professionals. This study is aimed at exploring the real experience and perceptions of transitional care services among healthcare professionals and PTBD patients who have been discharged with tubes and at providing references for future transitional care service development. The study uses a qualitative descriptive design. The reporting method followed Consolidated Criteria for Reporting Qualitative Research guidelines. Semistructured interviews were conducted with PTBD patients who had been discharged with tubes and multicentre healthcare professionals using the purpose sampling method. The thematic analysis method was used for analysis. ThirteenPTBD patients from one hospital and 12 healthcare professionals from three hospitals were interviewed. The analysis of the patient interview data revealed three themes, namely, recognition of the value of transitional care services, patients have some unmet needsand perception of transitional care service pathways. Six subthemes were also identified. The analysis of the interview data of healthcare professionals revealed two themes, namely, harvest and challenges in transitional care services work and expectations for future development of transitional care services. Four subthemes were also identified. The transitional care of discharged patients with PTBD tubes deserves the attention of clinical workers, and a series of measures should be taken to improve transitional care services. Patients were involved in the formulation of interview questions for this study, and during the interviews, patients presented their suggestions for transitional care services. Healthcare professionals participated in this study as interviewees, and no members of the public were involved in this study.

Cholecystitis in older patients following hip fracture: a case series and literature review

ObjectiveThis study’s aim is to describe the characteristics of perioperative acute cholecystitis in older patients with hip fracture.MethodsFrom January 1, 2018, to April 30, 2023, 7,746 medical records were retrospectively collected for patients aged ≥ 65 years who were hospitalised for hip fracture in Beijing Jishuitan Hospital, Capital Medical University. We reviewed 10 cases with confirmed diagnoses of acute cholecystitis.ResultsOf these 10 cases, five femoral neck fractures and five intertrochanteric fractures received orthopaedic surgery. The ratio of males to females was 2:8, the median age was 83.1 years (71–91 years), and there was a median BMI of 25.35 (15.56–35.16). 50% of cases had a poor functional capacity before fracture of below four metabolic equivalents. The median onset time of acute cholecystitis was five days (2–14 days) after fracture, including five cases before orthopaedic surgery and five cases after orthopaedic surgery. All patients had anorexia and fever during the course of the disease. In seven cases of calculous cholecystitis, two underwent percutaneous transhepatic biliary drainage, and one underwent percutaneous cholecystostomy. Two cases of calculous cholecystitis had poor prognosis; one died 49 days after fracture operation, and the reason for death was multiple organ failure caused by severe infection. The other one developed acute cerebellar infarction after gallbladder surgery through treatment in an intensive care unit and neurology department. The case was discharged with dysphasia, and the duration from fracture to discharge was 92 days.ConclusionThis is the first study on the characteristics of acute cholecystitis in older patients with hip fracture in China. The incidence of acute cholecystitis in our study was 0.13%, with a high risk of in-hospital mortality and elevated hospitalisation costs. Our 10 cases with hip fractures accompanied by acute cholecystitis have common characteristics of poor-to-moderate functional capacity before fracture, increased blood glucose levels and enhanced protein metabolism after fracture. The death and the severe case have similar characteristics of low BMI, multiple underlying diseases, high plasma osmotic pressure and calculous cholecystitis, which occurred after orthopaedic surgery. These issues require attention and prompt, active intervention. Related issues require further research.

Percutaneous Transhepatic Biliary Drainage for Malignant Biliary Obstruction in Advanced Solid Organ Malignancy: Clinical Outcomes and a Perspective on Quality of Life

Background: Malignant obstructive jaundice is associated with a poor prognosis. Patients can undergo percutaneous transhepatic biliary drainage (PTBD), but the impact it has on quality of life is not well understood.Objective: To assess the potential impact of PTBD on quality of life in patients with obstructive jaundice from advanced malignancy using surrogate markers including complications, hospital length of stay, readmission, reintervention, and mortality. Methods: A retrospective analysis of a single-centre cohort of all patients with advanced solid organ malignancy undergoing PTBD between April 2020 and February 2022. Data was collected from electronic medical records.Results: Among the sixteen patients, abdominal pain and cholangitis were observed in 62.5% and 37.5% patients, respectively. Peritonitis, biliary leak, perihepatic abscess, and haemobilia occurred in individual cases. The median hospital length of stay post PTBD was nine days. The 30-day readmission rate for PTBD-related complications was 31.3% with a median of three total readmissions per patient. The 30-day reintervention rate was 62.5%. The 30-day all-cause mortality was 25% (95% CI:8.9-53.3), which included one procedure-related death. Conclusions: Quality of life in patients with obstructive jaundice from advanced solid organ malignancy undergoing PTBD can be adversely impacted due to the high risk of complications, reintervention, hospitalisation, and mortality. Thorough patient assessments are crucial in selecting appropriate candidates for PTBD.

Biliary Leak after Pediatric Liver Transplantation Treated by Percutaneous Transhepatic Biliary Drainage-A Case Series.

Biliary leaks are a severe complication after pediatric liver transplantation (pLT), and successful management is challenging. The aim of this case series was to assess the outcome of percutaneous transhepatic biliary drainage (PTBD) in children with bile leaks following pLT. The necessity of additional percutaneous bilioma drainage and laboratory changes during therapy and follow-up was documented. All children who underwent PTBD for biliary leak following pLT were included in this consecutive retrospective single-center study and analyzed regarding site of leak, management of additional bilioma, treatment response, and patient and transplant survival. The courses of inflammation, cholestasis parameters, and liver enzymes were retrospectively reviewed. Ten children underwent PTBD treatment for biliary leak after pLT. Seven patients presented with leakage at the hepaticojejunostomy, two with leakage at the choledocho-choledochostomy and one with a bile leak because of an overlooked segmental bile duct. In terms of the mean, the PTBD treatment started 40.3 ± 31.7 days after pLT. The mean duration of PTBD treatment was 109.7 ± 103.6 days. Additional percutaneous bilioma drainage was required in eight cases. Bile leak treatment was successful in all cases, and no complications occurred. The patient and transplant survival rate was 100%. CRP serum level, leukocyte count, gamma-glutamyl transferase (GGT), and total and direct bilirubin level decreased significantly during treatment with a very strong effect size. Additionally, the gamma-glutamyl transferase level showed a statistically significant reduction during follow-up. PTBD is a very successful strategy for bile leak therapy after pLT.

Percutaneous transhepatic biliary drainage (PTBD) in patients with biliary leakage: Technical and clinical outcomes.

The purpose of this study is to evaluate the technical and clinical outcome of percutaneous transhepatic biliary drainage (PTBD) in patients with biliary leakage. All patients who underwent ultrasound-assisted PTBD between January 2017 and December 2021 due to biliary leakage with nondilated biliary systems were retrospectively evaluated for periprocedural characteristics, medical indications, technical success (successful placement of drainage catheter), clinical success (resolved leak without additional procedures), fluoroscopy time, procedure duration, and clinical outcomes. 74 patients with a mean age of 64.1 ± 15.1 years were identified. Surgery was the most common etiology of biliary leak with 93.2% of the cases. PTBD had a 91.8% (68/74) technical success rate and an 80.8% clinical success rate. The mean procedure and fluoroscopy duration were 43.5 and 18.6 minutes. Age > 65 years (P = .027) and left-sided drainage (P = .034) were significant risk factors of clinical failure. Procedure-related major complications were 2 bleedings from the liver and 1 bleeding from an intercostal artery (major complication rate 4%). PTBD is a feasible, safe, and effective treatment option in patients with biliary leakage with low complication rates.

Essential updates 2021/2022: Update in surgical strategy for perihilar cholangiocarcinoma.

Resection is the only potential curative treatment for perihilar cholangiocarcinoma (PHC); however, complete resection is often technically challenging due to the anatomical location. Various innovative approaches and procedures were invented to circumvent this limitation but the rates of postoperative morbidity (20%-78%) and mortality (2%-15%) are still high. In patients diagnosed with resectable PHC, deliberate and coordinated preoperative workup and optimization of the patient and future liver remnant are crucial. Biliary drainage is recommended to relieve obstructive jaundice and optimize the clinical condition before liver resection. Biliary drainage for PHC can be performed either by endoscopic biliary drainage or percutaneous transhepatic biliary drainage. To date there is no consensus about which method is preferred. The volumetric assessment of the future remnant liver volume and optimization mainly using portal vein embolization is the gold standard in the management of the risk to develop post hepatectomy liver failure. The improvement of systemic chemotherapy has contributed to prolong the survival not only in patients with unresectable PHC but also in patients undergoing curative surgery. In this article, we review the literature and discuss the current surgical treatment of PHC.

Use of gelatin sponge to seal the biliary tract after percutaneous transhepatic biliary drainage in patients with liver transplants.

Percutaneous transhepatic biliary drainage (PTBD) is commonly used in the treatment of malign and benign biliary pathologies. Certain complications after PTBD may occur, such as biliary fistula, biliary leakage, bilioma, and hematoma. The purpose of this study was to evaluate the safety and effectiveness of using a sterile gelatin sponge to seal the biliary tract after PTBD in patients with liver transplants to prevent complications. A total of 131 biliary drainages were introduced in 97 patients, and a sterile gelatin sponge was used to seal the biliary tract after removal of the biliary drainage catheter. The patients were immediately examined for complications using ultrasound and then followed up clinically unless imaging was required. Five fluid collections within the liver with a diameter <2 cm, consistent with hematoma or bilioma, were resolved spontaneously. No hematoma or bilioma required treatment, and no biliary leakage or fistula was detected. No compli¬cations related to the use of the sponge were observed. The use of a sterile gelatin sponge is a safe and effec-tive method for sealing the biliary tract to prevent complications after PTBD in patients with liver transplants.

Endoscopy Ultrasound-Guided Biliary Drainage Using Lumen Apposing Metal Stent in Malignant Biliary Obstruction.

This narrative review provides an overview of the application of endoscopic ultrasound-guided biliary drainage (EUS-BD), including EUS-guided gallbladder drainage (EUS-GBD), for the treatment of malignant biliary obstruction. EUS-BD has demonstrated excellent technical and clinical success rates, with lower rates of adverse events when compared with percutaneous trans-hepatic biliary drainage (PTBD). EUS-BD is currently the preferred alternative technique for biliary drainage (BD) in patients with distal malignant biliary obstruction (DMBO) after failed endoscopic retrograde cholangiopancreatography (ERCP). Particularly, this review will focus on EUS-BD performed with the use of lumen apposing metal stent (LAMS). The introduction of these innovative devices, followed by the advent of electrocautery-enhanced LAMS (EC-LAMS), gave the procedure a great technical implementation and a widespread application.

80 Has the global pandemic health and social situation affected the management of obstructive jaundice secondary to tumuor pathology? A review of our experience in two years of the pandemic

Abstract Objectives SARS-CoV-2(COVID19) infection forced a redistribution of hospital resources, including reduction and delay of scheduled surgical activity. We analysed the management of obstructive jaundice (OJ) in patients with potentially resectable periampullary pathology in a tertiary care centre during the pandemic. Methods Observational, single-centre, retrospective study, during the years 2020-2021. The main inclusion criterion was the indication for cephalic duodenopancreatectomy. Patients with criteria of unresectability or indication for neoadjuvant treatment were excluded. We analysed OJ drainage techniques (endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic biliary drainage (PTCD) as well as associated complications. Indications for drainage were: bilirubin &amp;gt;10 mg/dl, cholangitis or expected surgery &amp;gt;2 weeks after inclusion on the waiting list. Results We analysed 75 patients (53.3% male) with an age range of 28-80 years. 59% of patients required drainage by OJ, ERCP was performed in 23 cases and PTCD in 21 cases. Twenty-three stents were placed, 52.1% of which were metal-covered. The most frequent complications associated with ERCP (43.4%) were cholangitis and pancreatitis. The most frequent complication associated with PTCD (28.5%) was cholangitis. Conclusion The correct management of OJ secondary to resectable periampullary tumours is early surgery without preoperative drainage. In case drainage is necessary, the endoscopic approach with placement of a metallic stent seems to be the most indicated. In our series, the COVID19 pandemic led to more preoperative biliary drainage due to longer delays in surgical scheduling, as well as more PTCD approaches due to greater accessibility, this technique also being valid.

Comparison Study between ERCP and PTBD for Recurrent Choledocholithiasis in Patients Following Gastrectomy.

The recurrence rate of choledocholithiasis in the general population has been reported to exceed 10%. The incidence of cholelithiasis was reported to be higher in patients following gastrectomy than that in the general population. However, there is no study for recurrent choledocholithiasis incidence in patients following gastrectomy. This study aimed to evaluate the recurrence rate of choledocholithiasis and identify risk factors for recurrent choledocholithiasis in patients following gastrectomy. A retrospective analysis was performed on patients with gastrectomy history who underwent choledocholithiasis removal in Kyungpook National University Hospital between January 2011 and December 2019. Choledocholithiases were treated by endoscopic retrograde cholangiopancreatography (ERCP) (n = 41) or percutaneous transhepatic biliary drainage (PTBD) (n = 90). The gastrectomy type was classified as subtotal gastrectomy with Billroth I (18.3%), Billroth II (45.0%), and total gastrectomy with Roux-en-Y (36.6%). During a median follow-up period of 31.5 (range, 6-105) months, choledocholithiasis recurrence was noted in 19 of 131 patients (14.5%). In subgroup analysis, the ERCP group (24.4%) had higher choledocholithiasis recurrence than the PTBD group (10.0%). Stone removal modality (ERCP), no use of balloon sphincteroplasty, and the presence of periampullary diverticulum were significant risk factors for recurrent choledocholithiasis. In multivariate analysis, ERCP (hazard ratio (HR), 3.597; 95% confidence interval (CI): 1.264-10.204) CBD stricture (HR, 3.823; 95% CI: 1.118-13.080) and no use of balloon sphincteroplasty (HR, 4.830; 95% CI: 1.669-13.889) were risk factors for recurrent choledocholithiasis following stone removal. The incidence of CBD stones in patients who underwent gastrectomy is similar to that of the general population. ERCP, CBD stricture, and no use of balloon sphincteroplasty are potential risk factors for recurrent CBD stones following gastrectomy. When we consider PTBD disadvantages, the ERCP procedure with active use of balloon sphincteroplasty is recommended to decrease recurrent CBD stones.

Multifactorial Analysis of Biliary Infection in Patients with Hepato-pancreatico-biliary and Associated Intraabdominal Malignancies Admitted to a Teaching Hospital in Northern India.

Blockage of the biliary tract is commonly caused by malignant tumors leading to deranged liver function, responsible for poor prognosis and a high rate of bacteriobilia leading to mortality. We collected retrospective data from the hospital information system and laboratory registers in our department from 2021 to 2022 to evaluate biliary infections in patients with hepato-pancreatico-biliary and associated intraabdominal malignancies. A total of 118 (118/234, 50.43%) patients' bile samples were estimated in this study. Patients' average age was 53.02 ± 13.49 years, with more patients below the age of 65 years among those with infected bile samples. Eight patients were infected by 102 pathogenic microorganisms. The most common pathogenic microorganism responsible for biliary infection in patients with abdominal malignancies was Escherichia coli (38/102, 37.25%) followed by Klebsiella pneumoniae (21/102, 20.59%) and Enterococcus spp. (18/102, 17.65%). Underlying comorbidities like diabetes mellitus, hypothyroidism, hypoproteinemia, chronic liver disease, immunosuppression, chronic kidney disease, increased hospital stay, admission to the intensive care unit (ICU), and presence of percutaneous transhepatic biliary drain were statistically significant risk factors for isolation of multidrug-resistant pathogenic bacteria. Our study guided physicians in identifying the associated demographic characteristics, risk factors, and the spectrum of pathogens responsible for bacteriobilia in abdominal cancer patients along with the antibiotic resistance pattern among these isolates and better selection of antibiotics and antibiotic prophylaxis for patients at risk of developing biliary tract infections with multidrug-resistant pathogens.
