RESUMEN
Heterotopic pancreas is a rare congenital abnormality. The most common location is the stomach, duodenum and proximal jejunum. Rare locations are represented by the ampulla of Vater, esophagus, ileum, Meckel diverticulum, biliary tract, mesentery and spleen. We present the case of a 49 year old patient investigated for obstructive jaundice and diagnosed with an ampullar heterotopy of pancreas parenchyma, initially considered to be a malignant tumor. A Whipple pancreatoduodenectomy was performed with good postoperative evolution, the serum levels of bilirubin being normal after the first postoperative week.

We present a case involving a 67-year-old patient with a medical history of gastric bypass who was recently diagnosed with a 6-centimeter duodenal mass causing biliary duct stenosis. Despite our best efforts, we were unable to access this tumor endoscopically, necessitating surgical intervention. During the surgical exploration, we discovered a duodenal diverticulum filled with stones, leading to the obstruction of the biliary ductâ?"a manifestation of Lemmel syndrome. This rare condition is characterized by obstructive jaundice in the absence of choledocholithiasis or tumors and is secondary to dilatation of peri-ampullary diverticula. While it is typically managed through endoscopy, our diagnostic and therapeutic approach was complicated by the patient's history of bariatric surgery (gastric bypass), making endoscopic access impossible despite our multiple attempts. This case report sheds light on the challenges posed by the concurrence of a rare pathology and surgically modified anatomy, which is increasingly encountered in daily surgical practice. In such situations, exploratory surgery continues to play a significant role.

BACKGROUND: Prolonged obstructive jaundice (OJ), associated with resectable pancreatic pathology, has many deleterious effects that are potentially rectifiable by preoperative biliary drainage (POBD) at the cost of increased postoperative infective complications. The aim of this study is to assess the impact of POBD on intraoperative biliary cultures (IBCs) and surgical outcomes in patients undergoing pancreatic resection. METHODS: Data from patients at Groote Schuur Hospital, Cape Town, between October 2008 and May 2019 were analysed. Demographic, clinical, and outcome variables were evaluated, including perioperative morbidity, mortality, and 5-year survival. RESULTS: Among 128 patients, 69.5% underwent POBD. The overall perioperative mortality in this study was 8.8%. The POBD group had a significantly lower perioperative mortality rate compared to the non-drainage group (5.6% vs. 25.6%). POBD patients had a higher incidence of surgical site infections (55.1% vs. 23.1%), polymicrobial growth from IBCs and were more likely to culture resistant organisms. Five-year survival was similar in the two groups. CONCLUSION: POBD was associated with a high incidence of resistant organisms on the IBCs, a high incidence of surgical site infections and a high correlation between cultures from the surgical site infection and the IBCs.

The risk of cholangitis after ERCP implantation in malignant obstructive jaundice patients remains unknown. To develop models based on artificial intelligence methods to predict cholangitis risk more accurately, according to patients after stent implantation in patients' MOJ clinical data. This retrospective study included 218 patients with MOJ undergoing ERCP surgery. A total of 27 clinical variables were collected as input variables. Seven models (including univariate analysis and six machine learning models) were trained and tested for classified prediction. The model' performance was measured by AUROC. The RFT model demonstrated excellent performances with accuracies up to 0.86 and AUROC up to 0.87. Feature selection in RF and SHAP was similar, and the choice of the best variable subset produced a high performance with an AUROC up to 0.89. We have developed a hybrid machine learning model with better predictive performance than traditional LR prediction models, as well as other machine learning models for cholangitis based on simple clinical data. The model can assist doctors in clinical diagnosis, adopt reasonable treatment plans, and improve the survival rate of patients.

OBJECTIVE: Aim: To improve treatment outcomes of patients with unresectable pancreatic head cancer complicated by obstructive jaundice by improving the tactics and techniques of surgical interventions. PATIENTS AND METHODS: Materials and Methods: Depending on the treatment tactics, patients were randomised to the main group (53 people) or the comparison group (54 people). The results of correction of obstructive jaundice by Roux-en-Y end to side hepaticojejunostomy (main group) and common bile duct prosthetics with self-expanding metal stents (comparison group) were compared. RESULTS: Results: The use of self-expanding metal stents for internal drainage of the biliary system compared to hepaticojejunostomy operations reduced the incidence of postoperative complications by 29.9% (χ2=13.7, 95% CI 14.38-44.08, p=0.0002) and mortality by 7.5% (χ2=4.16, 95% CI -0.05-17.79, p=0.04). Within 8-10 months after biliary stenting, 11.1% (6/54) of patients developed recurrent jaundice and cholangitis, and another 7.4% (4/54) of patients developed duodenal stenosis with a tumour. These complications led to repeated hospitalisation and biliary restentation in 4 (7.4%) cases, and duodenal stenting by self-expanding metal stents in 4 (7.4%) patients. CONCLUSION: Conclusions: The choice of biliodigestive shunting method should be selected depending on the expected survival time of patients. If the prognosis of survival is up to 8 months, it is advisable to perform prosthetics of the common bile duct with self-expanding metal stents, if more than 8 months, it is advisable to perform hepaticojejunal anastomosis with prophylactic gastrojejunal anastomosis.

The main cause of distal biliary malignant obstructive jaundice (DBMOJ) is the stricture of the extrahepatic biliary tract by malignant tumors, including pancreatic head and uncinate process cancer, low-grade cholangiocarcinoma, duodenal cancer, papillary duodenal cancer and other malignant tumors. The most effective treatment is radical pancreaticoduodenectomy. However, preoperative obstructive jaundice can affect the patient's liver function and blood coagulation function, increase local inflammation and oedema, and make surgery more difficult. Patients with severe obstructive jaundice require preoperative biliary drainage, which can be achieved by various methods, including ultrasound endoscopic biliary drainage (EUS-EBD) and endoscopic retrograde biliary drainage (ERBD). The latter is mainly divided into endoscopic nasobiliary drainage and endoscopic biliary stent. Some patients underwent percutaneous transhepatic biliary drainage (PTBD) when ERBD and EUS-EBD failed. In this study, we aimed to identify PTBD in DBMOJ and to further investigate the role of the puncture pathway in DBMOJ. The relationship between PTBD and bile duct internal diameter was confirmed by analysing and collating clinical data. In this study, DBMOJ was grouped according to bile duct internal diameter and liver function was used as an indicator to examine the improvement in liver function with PTBD in patients undergoing DBMOJ. Analysis of puncture complications showed that PTBD puncture was safe. DBMOJ with different bile duct internal diameters had different rates of liver function improvement after PTBD. The right-side approaches had significantly lower alanine aminotransferase (ALT) and alanine transaminase (AST) than the left-side approaches. This study showed that PTBD for DBMOJ is associated with a low complication rate and good reduction of jaundice. Liver function recovery was faster in patients with DBMOJ treated with PTBD in the right-sided approach compared with the left-sided approach. PTBD is an effective tool to be used in patients who have failed ERBD and EUS-EBD.

The necessity of biliary drainage before pancreaticoduodenectomy remains controversial in cases involving malignant obstructive jaundice; however, the benefits of biliary drainage have been reported in cases with severe hyperbilirubinemia. Herein, we present the case of a 61-year-old man suffering from jaundice due to distal cholangiocarcinoma. In this case, obstructive jaundice was refractory to repeat endoscopic drainage and bilirubin adsorption. Hyperbilirubinemia persisted despite successful implementation of biliary endoscopic sphincterotomy and two rounds of plastic stent placements. Stent occlusion and migration were unlikely and oral cholagogues proved ineffective. Owing to the patient's surgical candidacy and his aversion to nasobiliary drainage due to discomfort, bilirubin adsorption was introduced as an alternative therapeutic intervention. Following repeated adsorption sessions, a gradual decline in serum total bilirubin levels was observed and pancreaticoduodenectomy was scheduled. The patient successfully underwent pancreaticoduodenectomy with portal vein resection and reconstruction and D2 lymph node dissection. After the surgery, the serum bilirubin levels gradually decreased and the patient remained alive, with no recurrence at 26 months postoperatively. Therefore, this case highlights the feasibility and safety of performing pancreaticoduodenectomy in patients with severe, refractory jaundice who have not responded to repeated endoscopic interventions and have partially responded to bilirubin adsorption.

INTRODUCTION: Obstructive jaundice is the most common symptom of malignant diseases of the extrahepatic biliary system and necessitates either non-operative or operative biliary bypass. Because of percutaneous and endoscopic approaches, the use of palliative surgical procedures has decreased in recent years. However, in resource-limited situations, open biliary bypasses remain a viable option. This study aimed to identify factors associated with adverse perioperative outcomes following open biliary bypass. METHODS: From June 2022 to May 2023, 69 patients underwent open biliary bypass for malignant biliary obstruction. Postoperative morbidity and mortality within 30 days of surgery were assessed. A Kaplan-Meier was used for categorical variables, and a log-rank test was used to determine the statistically significant difference between variables. A Cox regression analysis was conducted to identify factors associated to time to develop complications. RESULTS: The hazard of developing complications among those with preoperative cholangitis was 2.49 times higher than those without preoperative cholangitis (HR 2.49, 95% CI [1.06, 5.84]). For every hour increment in the length of surgery, the hazard of getting complications increased by 2.47 times (HR 2.47, 95% CI [1.28, 4.77]). As serum bilirubin increased by 1 mg/dl, the hazard of developing complications increased by 14% (HR 1.14, 95% CI [1.03, 1.17]). CONCLUSION: Patients who had long operation times, preoperative cholangitis, and elevated total bilirubin levels are at increased risk for poor perioperative outcomes. Clinicians may use these results to optimize these patients to decrease their elevated risk of serious morbidity and mortality.

Objective: To analyze the clinical application value of a novel magnetic navigation ultrasound (MNU) combined with digital subtraction angiography (DSA) dual-guided percutaneous transhepatic biliary drainage (PTCD) through the right hepatic duct for the treatment of malignant obstructive jaundice. Methods: Randomized controlled trial. The clinical data of 64 patients with malignant obstructive jaundice requiring PTCD through the right hepatic duct at the Hepatobiliary Center of the First Affiliated Hospital of Nanjing Medical University (Jiangsu Province People's Hospital) from December 2018 to December 2021 were retrospectively analyzed. The MNU group (n=32) underwent puncture guided by a novel domestic MNU combined with DSA, and the control group (n=32) underwent puncture guided by traditional DSA. The operation time, number of punctures, X-ray dose after biliary stenting as shown by DSA, patients' tolerance of the operation, success rate of the operation, pre- and post-operative total bilirubin, and incidence of postoperative complications were compared between the two groups. Results: The operation time of the MNU group was significantly shorter than that of the control group [(17.8±7.3) vs. (31.6±9.9) min, t=-6.35,P=0.001]; the number of punctures in the MNU group was significantly lower [(1.7±0.6) vs. (6.3±3.9) times, t=-6.59, P=0.001]; and the X-ray dose after biliary stenting as shown by DSA in the MNU group was lower than that in the control group [(132±88) vs. (746±187) mGy, t=-16.81,P<0.001]; Five patients in the control group were unable to tolerate the operation, and two stopped the operation, however all patients in the MNU group could tolerate the operation, and all completed the operation, with a success rate of 100% (32/32) in the MNU group compared to 93.8%(30/32) in the control group; the common complications of PTCD were biliary bleeding and infection, and the incidence of biliary bleeding (25.0%, 8/32) and infection (18.8%, 6/32) in the MNU group was significantly lower than that in the control group, 53.1% (17/32) and 28.1% (9/32), respectively. Conclusion: Magnetic navigation ultrasound combined with DSA dual-guided PTCD through the right biliary system for the treatment of malignant obstructive jaundice is safe and feasible.

BACKGROUND AND AIM: The 10-mm self-expandable metal stent (SEMS) is the standard for endoscopic transpapillary biliary drainage before pancreatic cancer surgery. However, the efficacy of stents thinner than 10 mm has not been adequately validated. Therefore, we aimed to evaluate the safety of a 6-mm fully covered SEMS (FCSEMS) for distal malignant biliary obstruction (DMBO) during preoperative chemotherapy for pancreatic cancer. METHODS: This was a single-arm, multicenter, prospective phase II study of endoscopic transpapillary initial biliary drainage for DMBO before pancreatic cancer surgery. The primary endpoint was stent-related adverse events, and the key secondary endpoint was the non-recurrent biliary obstruction (non-RBO) rate during the observation period for both resectable (R) and borderline resectable (BR) pancreatic cancers. RESULTS: The study enrolled 33 patients, among whom 32 received the study treatment. There were 23 and 9 cases of R and BR pancreatic cancers, respectively. The technical and clinical success rates were 97.0% and 90.1%, respectively. The stent-related adverse event rate was 3.1% (n = 1, acute pancreatitis) (95% confidential interval, 0.00-16.2), which met the criteria to be considered safe. The overall non-RBO rate during the observation period (median 96 days) was 78.1% (82.6% and 66.7% for R and BR pancreatic cancer cases, respectively). CONCLUSIONS: The 6-mm FCSEMS is an extremely safe metallic stent with a low stent-related adverse event rate of 3.1% for preoperative biliary drainage in pancreatic cancer. It is considered the optimal stent for preoperative biliary drainage in terms of the non-RBO rate. UMIN Clinical Trial Registry (UMIN-CTR 000041704).

Objective: The purpose of this study was to explore the clinical benefits of establishing an enteral nutrition (EN) pathway via percutaneous transhepatic cholangiography drainage (PTCD) catheterization in patients with late-stage malignant obstructive jaundice (MOJ).Methods: We selected 30 patients diagnosed as having late-stage MOJ with malnutrition. A dual-lumen biliary-enteral nutrition tube was placed via PTCD along with a biliary stent implantation. Postoperative EN was provided, and we observed the time taken for tube placement, its success rate, complications, and therapeutic efficacy.Results: Tube placement was successful in all 30 patients with an average procedural time of 5.7 ± 1.4 min with no tube placement complications. Compared to preoperative measures, there was a significant improvement in postoperative jaundice reduction and nutritional indicators one month after the procedure (p < 0.05). Post-placement complications included tube perileakage in 5 cases, entero-biliary reflux in 4 cases, tube blockage in 6 cases, tube displacement in 4 cases, accidental tube removal in 3 cases, and tube replacement due to degradation in 8 cases, with tube retention time ranging from 42 to 314 days, averaging 124.7 ± 37.5 days. All patients achieved the parameters for effective home-based enteral nutrition with a noticeable improvement in their quality of life.Conclusion: In this study, we found that the technique of establishing an EN pathway via PTCD catheterization was minimally invasive, safe, and effective; the tube was easy to maintain; and patient compliance was high. It is, thus, suitable for long-term tube retention in patients with late-stage MOJ.

OBJECTIVE: To improve the outcomes in patients with malignant obstructive jaundice using intraluminal stenting. MATERIAL AND METHODS: The present study included 62 patients with clinical symptoms of malignant obstructive jaundice. In the main group, we performed biliary stenting with self-expanding multi-perforated stents (Hanarostent Multi-hole Biliary). Microscopic perforations of these stents prevent migration and reduce the risk of blocking the cystic and main pancreatic ducts. In the control group, stenting was performed with fully and partially covered self-expanding stents. RESULTS: Lower incidence of obstructive cholecystitis and acute pancreatitis in the main group was associated with multiperforated stents reducing the risk of blocking the main pancreatic and cystic ducts. CONCLUSION: In our study, multiperforated stents excluded migration and reduced the incidence of complications (acute cholecystitis from 11.5 to 3.8%, acute pancreatitis from 15.3 to 7.7%).

INTRODUCTION: Endoscopic transpapillary approach by endoscopic retrograde cholangiopancreatography (ERCP) is the established technique for preoperative biliary drainage (PBD). Recently, endoscopic ultrasound-guided biliary drainage (EUS-BD) has been reported to be a useful alternative technique after ERCP fail. However, the optimal strategy remain controversial. AREA COVERED: This review summarizes the literature on EUS-BD techniques for PBD with a literature search using PubMed, Web of Science, and the Cochrane Central Register of Controlled Trials database between 2000 and 2023 using keywords for 'preoperative biliary drainage' and all types of EUS-BD techniques. EXPERT OPINION: As there is no consensus on the optimal EUS-BD technique for PBD, selection of the EUS-BD approach depends on the patient's condition, the biliary obstruction site, the anastomosis after surgical intervention, and the preference of the endoscopist. However, we consider that EUS-HGS using a dedicated plastic stent may have some advantages in the adverse impact of surgical procedure because the location where the fistula is created by EUS-HGS is away from the site of the surgical procedure. Although there remain many issues that require further investigation, EUS-BD can be a feasible and safe alternative method of PBD for malignant biliary obstruction after ERCP fail.

OBJECTIVE: To evaluate the effectiveness of minimally invasive technologies of lithotripsy and hydraulic antegrade lithoextraction in complex treatment of choledocholithiasis. MATERIAL AND METHODS: In the main group, 74 patients with choledocholithiasis underwent complex treatment with minimally invasive lithotripsy and hydraulic antegrade lithoextraction. In the control group, 177 patients with choledocholithiasis complicated by obstructive jaundice underwent complex treatment without minimally invasive lithotripsy and hydraulic antegrade lithoextraction. RESULTS: Both groups were characterized by significant decrease of serum bilirubin, markers of cytolysis and cholestasis with regression of clinical manifestations of obstructive jaundice. At the same time, early and delayed postoperative complications were significantly more common in the control group. Most of these complications accounted for interventions through laparotomy such as external drainage of the common bile duct and hepaticojejunostomy. There were no similar procedures in the main group due to the use of minimally invasive technologies of lithotripsy and antegrade hydraulic lithoextraction. CONCLUSION: Minimally invasive lithotripsy and antegrade hydraulic lithoextraction are safe alternatives to traditional methods of lithoextraction and can be recommended in case of ineffective laparoscopic and retrograde endoscopic lithoextraction.

OBJECTIVE: To improve treatment outcomes in patients with Klatskin tumor and obstructive jaundice by using of endoscopic bilioduodenal stenting. MATERIAL AND METHODS: There were 1904 transpapillary interventions between August 2017 and February 2022. Endoscopic bilioduodenal stenting was performed in 250 patients including 25 (10%) ones with Klatskin tumor. RESULTS: Bilioduodenal plastic and self-expanding stents were installed in 19 (76%) and 6 (24%) patients, respectively. In Klatskin tumor type I, 11 patients (44%) underwent bilioduodenal stenting of common hepatic duct with plastic stent; 5 (20%) patients with Klatskin tumor type II received self-expanding stents. In case of tumor type IIIA, 3 (12%) patients underwent stenting of the right lobar duct with plastic stent. Four (16%) patients with Klatskin tumor type III B underwent stenting of the left lobar duct. Two 2 (8%) patients with Klatskin tumor type IV underwent bilateral bilioduodenal stenting with plastic and bifurcation self-expanding stents. Peroral cholangioscopy using the SpyGlass DS system was performed in 4 (16%) patients. No intraoperative complications were identified. One (4%) patient developed gastrointestinal bleeding in 2 postoperative days after retrograde intervention that did not require surgery. Moreover, 1 (4%) patient with distal dislocation of plastic bilioduodenal stent required redo bilioduodenal stenting. Three (12%) patients died from multiple organ failure despite adequate biliary decompression, and 22 (88%) patients were discharged in 8±5 days after retrograde intervention. CONCLUSION: Bilioduodenal stenting as minimally invasive and physiological method was highly effective for obstructive jaundice in patients with Klatskin tumor. Peroral cholangioscopy using the SpyGlass system provides effective and safe direct visualization of the biliary tract, as well as biopsy for morphological verification and prescription of chemotherapy in patients with intraductal growth of tumor.

Hepatic artery aneurysms (HAA) are rare (20% of all visceral arteries). Most often, HAAs are asymptomatic and detected at autopsy. However, their ruptures and/or bleeding following pressure ulcers in visceral gastrointestinal organs are a significant clinical and diagnostic problem. We present 2 patients with obstructive jaundice and hemobilia. Diagnostics revealed aneurysm of the right hepatic artery with arterio-biliary fistula. Life-threatening hemobilia is a consequence of HAA rupture into biliary system. Endovascular approach is preferable for HAA without clinical manifestations. Awareness of this disease is important for early detection and active surgical intervention before possible complications.

Liver failure in patients with obstructive jaundice is a significant contributor to mortality within this patient cohort. The exact mechanism and triggers of this occurrence are yet to be fully understood. With this in mind, our study aimed to assess the correlation between the urinary 6 ß-OHC/C ratio and various biochemical parameters of liver function. Furthermore, we conducted genotyping of CYP3A4*22 (rs35599367), CYP3A5*3 (rs776746) polymorphic markers to investigate the potential effects of their variants on the probability of liver failure in obstructive jaundice. Our study included 75 patients diagnosed with severe obstructive jaundice. All test subjects underwent functional liver tests, and control blood tests were administered on the seventh day following biliary decompression. Patients were categorized into two groups: group 1 - patients without liver failure (n = 60) and group 2 - patients with liver failure (n = 15). Laboratory indexes such as 6 ß -OHC concentration and 6 ß- OHC/cortisol ratio can serve as significant predictors of liver failure in patients with moderate and severe degree obstructive jaundice after biliary decompression. Based on the study of "wild" and polymorphic variants of CYP3A4*22 (CC and CT) and polymorphism of CYP3A5*3A6986G (GG, GA, AA), it was discovered that liver failure in the CYP3A4*22 variant may be associated with the CC genotype, and in the CYP3A5*3 variant - with the GA genotype. Hence, the determination of 6ß- OHC concentration and 6ß- OHC/C ratio, as well as the analysis of polymorphic and "wild" variants of CYP3A4*22 (CC and CT) and CYP3A5*3 polymorphism A6986G (GG, GA, AA), may play a crucial role in predicting liver failure in patients with obstructive jaundice.

Biliary metal stent implantation is an effective treatment for malignant obstructive jaundice. But it's well known that stents put in for a long time can become occluded and cause jaundice and cholangitis. At this time, endoscopic intervention is usually required to replace the stent or re-insert the stent. Re-cannulation for metal stent occlusion is challenging because the guide wire may pass through the side holes of the uncovered metal stents, resulting in prolonged surgical time and exposure to radiation. Here we present a small tip that may help endoscopists complete the re-cannulation of an uncovered metal stent in a very short time.
