Impact of the COVID-19 pandemic on the treatment of acute cholangitis caused by choledocholithiasis: A single-center retrospective study in Japan.

Objectives: This study aimed to determine the impact of the coronavirus disease 2019 (COVID-19) pandemic on the treatment of acute cholangitis caused by choledocholithiasis. Methods: The Japanese government declared a state of emergency in April 2020 due to the COVID-19 pandemic. We retrospectively reviewed the medical records of 309 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) for acute cholangitis caused by choledocholithiasis between April 2017 and December 2022. Results: Patients were categorized into a pregroup (n = 134) and a postgroup (n = 175), depending on whether they were diagnosed before or after the state of emergency declaration. The total number of ERCP cases and the number of ERCP cases with endoscopic stone removals increased after the state of emergency declaration. Compared with the pregroup, the numbers of patients with performance status of 0-1 and surgically altered anatomy increased, whereas the numbers of patients taking oral antiplatelets or anticoagulants and those with cerebrovascular disease decreased in the postgroup. The number of single-stage endoscopic stone removals increased and hospital stays were significantly shorter in the postgroup. No differences in adverse event rates were detected between the two groups. Conclusions: Although our hospital provides tertiary care, the number of patients with cholangitis in good general condition and no underlying disease increased after the state of emergency declaration. The COVID-19 pandemic resulted in an increase in the number of single-stage endoscopic treatments and shortened hospital stays for patients with acute cholangitis caused by choledocholithiasis. No safety issues with ERCP were detected, even during the pandemic.

Unilateral drainage and chemotherapy prolong the patency of a plastic stent placed above the sphincter of Oddi in patients with malignant hilar biliary obstruction.

Objectives: To evaluate the results of inside stent therapy for unresectable malignant hilar biliary obstruction and identify factors related to stent patency duration. Methods: Of 44 patients who underwent initial inside-stent placement above the sphincter of Oddi from April 2017 to December 2022, 42 with the resolution of jaundice (clinical success rate, 95.5%) were retrospectively analyzed. Univariate and multivariate logistic regression analysis identified factors associated with stent patency duration. Results: Univariate analysis revealed significant differences in the drainage method (406 days for unilateral drainage vs. 305 days for bilateral drainage of the right and left liver lobes, p = 0.022) with or without chemotherapy (406 days with vs. 154 days without, p = 0.038). Multivariate analysis (Cox proportional hazards analysis) revealed similar results, with unilateral drainage (p = 0.031) and chemotherapy (p = 0.048) identified as independent factors associated with prolonged stent patency. Early adverse events were observed in two patients (4.8%; one cholangitis, one pancreatitis). Conclusions: Inside-stent therapy was safely performed in patients with malignant hilar biliary obstruction. Simple unilateral drainage and chemotherapy may prolong stent patency.

Embryonal Rhabdomyosarcoma of the Bile Ducts Causing Obstructive Jaundice in a Child: A Case Report.

Jaundice in older children can occur when any obstruction is found within the bile ducts, either from bile stones, parasites, choledochal cysts and rarely, secondary to tumors. We present a previously well, 10-year-old Filipino boy with three-week history of progressive jaundice and tea-colored urine, and was initially assessed to have biliary ascariasis. Ultrasound showed a heterogeneous focus spanning the gallbladder neck and confirmed on endoscopic retrograde cholangiopancreatography as an exophytic mass at the ampulla of Vater. Tumor biopsy and immunohistochemical staining confirmed the diagnosis of Embryonal Rhabdomyosarcoma of the Bile Ducts. Chemotherapy was initiated to reduce the size of the tumor before any surgical intervention could be attempted. Despite chemotherapy, the tumor progressively grew. He acquired a respiratory infection which led to sepsis and his eventual demise. The disease should be considered in the differential diagnosis of a child with obstructive jaundice after exclusion of other more common causes.

Meandering main pancreatic duct syndrome: a single-center cohort study and aggregated review.

Background: Meandering main pancreatic duct (MMPD) refers to an uncommon ductal variant of the normal smooth curvilinear course of the pancreatic duct. More specifically, MMPD is characterized by a hairpin (reverse Z-type) or loop (loop-type) turn in the pancreatic head. It has been suggested as a predisposing factor for the development of pancreatitis. Studies regarding treatment are scarce. Methods: We conducted a narrative review of the current literature regarding MMPD. Additionally, we present a cohort of 9 symptomatic patients treated endoscopically at our tertiary center. Results: Seven retrospective cohort studies and 4 case reports were included in our review. Only 1 study focuses on the clinical significance of MMPD and describes a positive association between MMPD and the onset of pancreatitis, especially recurrent acute pancreatitis. Only 1 case reports an endoscopic treatment. In our cohort of 9 MMPD patients, 7 did indeed present with recurrent acute pancreatitis. Endotherapy provided substantial regression of symptoms in 6 patients, all of whom had signs of ductal hypertension. Conclusions: Our review shows the scarcity of data regarding MMPD, especially concerning treatment, in the current literature. With our cohort, we not only hope to raise awareness of this often-neglected entity of recurrent acute pancreatitis, but also support the case for endotherapy for the first time in 9 symptomatic MMPD patients, especially in the presence of ductal hypertension.

Comparative efficacy of endoscopic ultrasound-guided biliary drainage versus endoscopic retrograde cholangiopancreatography as first-line palliation in malignant distal biliary obstruction: a systematic review and meta-analysis.

Background: Malignant distal biliary obstruction (MDBO) is a challenging clinical condition commonly managed with endoscopic retrograde cholangiopancreatography (ERCP). However, endoscopic ultrasound-guided biliary drainage (EUS-BD) has emerged as an alternative, especially in complex cases where ERCP fails or is deemed risky. This study aimed to compare the efficacy, safety and cost-effectiveness of EUS-BD vs. ERCP in the palliation of MDBO. Methods: We conducted a systematic review and meta-analysis, following PRISMA guidelines. Three databases were searched up to December 2023, including MEDLINE/PubMed, OVID and the Cochrane Central Register of Controlled Trials, for studies comparing EUS-BD with ERCP. Primary outcomes were technical and clinical success rates, while secondary outcomes included procedural times, hospital stay duration, 30-day mortality, reintervention rates, and adverse events such as pancreatitis. Results: Seven studies involving 1245 patients met the inclusion criteria. The meta-analysis revealed that EUS-BD had a technical success rate of 92%, compared to 85% for ERCP. Clinical success rates were similar for both EUS-BD and ERCP, at approximately 89%. EUS-BD was associated with a significantly lower incidence of pancreatitis (2% vs. 10% for ERCP). Conclusions: EUS-BD offers a viable and potentially superior alternative to ERCP for the primary palliation of MDBO, particularly in terms of technical success and a lower risk of pancreatitis. These findings support the adoption of EUS-BD in clinical settings equipped to perform this technique, though future research should focus on long-term outcomes and further economic analysis to solidify these recommendations.

Ductal Intervention in Chronic Pancreatitis: Impact on Glycemic Control and Endocrine Insufficiency Management.

Background and aim Pancreatic endotherapy has been established as a viable and effective modality for the management of pain in chronic pancreatitis (CP). However, its impact on endocrine insufficiency has been rarely reported. In this retrospective study, we aimed to assess the impact of endotherapy on glycemic status and the management of diabetes in these patients. Methods A retrospective review of a prospectively maintained database of patients with CP with pain presenting to the King Edward Memorial Hospital and Seth Gordhandas Sunderdas Medical College, Mumbai, India, from December 2021 to May 2023 was done. Detailed clinical, laboratory, imaging, and treatment data were recorded. Endocrine dysfunction was defined as glycosylated hemoglobin (Hba1C) ≥6.5 g/dl. The status of endocrine function (Hba1C values) before and after endotherapy, as well as the requirement of oral hypoglycemic agent (OHA) and/or insulin, was recorded. Results One hundred forty-one patients underwent endoscopic retrograde cholangiopancreatography for the management of pain (mean age: 35 years, 74.5% males). Prior to endotherapy, pathological endocrine dysfunction was seen in 60 patients (42.5%). The mean HbA1c value was 8.46 g/dl (4.5-16.1g/dl). OHAs alone were used in 13/60 (21.6%), and 34/60 (56.6%) required insulin. A combination of OHA and insulin was required in 13/60 (21.6%) of patients. Post-endotherapy, none of the patients were on a combination of OHAs and insulin; 5/13 (38.4%) patients were on OHAs alone, while 8/13 (61.5%) patients were shifted to insulin. Out of the total 47 patients who required insulin, insulin could be stopped in 15/47 (31.9%) of patients. Patients who demonstrated improvement in endocrine dysfunction had significantly lower HbA1c values (6.38 vs. 8.07 g/dl, p < 0.001), a higher proportion of patients with idiopathic pancreatitis (73.3% vs. 22.2%, p = 0.004), and a lower proportion of patients with concomitant exocrine insufficiency (13.3% vs. 53.3%, p = 0.007). Conclusions One-third of the patients had improvements in endocrine dysfunction. Early ductal intervention in a selected subset of patients with CP may have the potential to improve glycemic status.

Endoscopic assessment of minor papilla morphology: Predictors of successful cannulation and procedural pancreatitis risk in minor papilla endotherapy.

BACKGROUND: We evaluated for predictors of successful cannulation and post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in minor papilla endotherapy (MPE), emphasizing endoscopic minor papilla morphology. METHODS: We retrospectively analyzed 232 MPEs in 65 patients, assessing minor papilla morphology based on three features: bulge as "prominent" or "subtle," mucosal appearance as "papilla-like" resembling the main papilla or "SMT-like" akin to a gastrointestinal submucosal tumor, and orifice visibility as "clear" or "unclear." Cannulation success was evaluated in 65 enrolled patients, with PEP risk assessed in all 232 MPEs. RESULTS: Minor papilla morphology was categorized as prominent/subtle bulge in 42/23 patients, papilla-like/SMT-like mucosal appearance in 42/23, and clear/unclear orifice visibility in 24/41. Cannulation succeeded in 54/65 patients (83%). A papilla-like appearance and clear orifice visibility was significantly associated with cannulation success. PEP incidence was 5.2% and predominantly mild. A papilla-like appearance significantly decreased PEP incidence, while precutting technique and orifice dilation significantly increased PEP risk. CONCLUSION: Evaluating minor papilla morphology may help predict cannulation success and PEP risk in MPE. A papilla-like mucosal appearance prognosticates cannulation success and reduced PEP risk, with clear orifice visibility serving as a success predictor. These findings provide practical guidance for preprocedural planning by emphasizing the importance of minor papilla morphology evaluation.

Impact of timing of ERCP on long term outcomes of ERCP for acute cholangitis - A single center retrospective study.

INTRODUCTION: Acute cholangitis is a critical medical emergency. The association between the timing of ERCP and clinical outcomes of acute cholangitis is still debated. The current study aims to evaluate whether ERCP within 48 h (urgent) is associated with improved long term clinical outcomes. METHODS: This study is a single-center retrospective analysis of a prospectively maintained database. All patients admitted with acute cholangitis as per Tokyo guidelines at AIG Hospitals, Hyderabad between January 2022 to December 2022 were included. We evaluated the association between urgent ERCP and length of hospital stay, need for reintervention and readmissions, and mortality. RESULTS: A total of consecutive 301 patients underwent ERCP for acute cholangitis; of which 217 patients (31.3 % females; mean age 54.02 ± 14.9 years) underwent urgent ERCP. The remaining 84 (32.1 % females; mean age 56.56 ± 13.9 years) underwent routine ERCP. Fifty-eight (26.7 %) and 22 (26.2 %) patients with Grade III underwent urgent and routine ERCP respectively. The median (IQR) hospital stay for urgent ERCP was 8.00 (6.00 - 11.00) days and for routine ERCP was 11.00(8.00 - 15.00; p value 0.0001), with similar hospital stay post ERCP (p 0.26). There was no significant difference in mortality upto one year between patients who underwent urgent (22.1 %;48/217) or routine ERCP (31.0 %;26/84, p 0.135). The cox proportional hazard model showed that mortality is independently associated with older age (HR 1.034;95 %CI: 1.013 - 1.054; p 0.001) and malignancy (HR 8.64;95 %CI:4.728 - 15.790; p 0.0001). There was no significant difference between two groups in terms of need for reinterventions and readmissions. CONCLUSIONS: Urgent ERCP for acute cholangitis is associated comparable overall mortality, need for reinterventions, and readmissions with decreased total length of hospital stay. There is an unmet need to confirm these findings by randomized controlled studies.

Comparison of radiation-shielding curtains for endoscopic retrograde cholangiopancreatography staff.

Occupational radiation exposure to the eye lens of medical staff during endoscopic retrograde cholangiopancreatography (ERCP) should be kept low so as not to exceed annual dose limits. Dose should be low to avoid tissue reactions and minimizing stochastic effects. It is known that the head and neck of the staff are exposed to more scattered radiation in an over-couch tube system than in a C-arm system (under-couch tube). However, this is only true when radiation-shielding curtains are not used. This study aimed to compare the protection radiation to the occupationally exposed worker between a lead curtain mounted on a C-arm system and an ERCP-specific lead curtain mounted on an over-couch tube system. A phantom study simulating a typical setting for ERCP procedures was conducted, and the scattered radiation dose at four staff positions were measured. It was found that scattered radiation doses were higher in the C-arm with a lead curtain than in the over-couch tube with an ERCP-specific lead curtain at all positions measured in this study. It was concluded that the over-couch tube system with an ERCP-specific lead curtain would reduce the staff eye dose by less than one-third compared to the C-arm system with a lead curtain. For the C-arm system, it is necessary to consider more effective radiation protection measures for the upper body of the staff, such as a ceiling-suspended lead screen or another novel shielding that do not interfere with procedures.

Extraction Basket Entangled in Surgical Sutures in Common Bile Duct Forty-Five Years After Hepatobiliary Surgery: A Bizarre Adverse Event of Endoscopic Retrograde Cholangiopancreatography.

Endoscopic retrograde cholangiopancreatography (ERCP) is an important technique for treating biliary obstruction. A case report of a 75-year-old male with diagnosed choledocholithiasis and cholangitis was presented. He had a history of hepatic surgery 45 years ago, and during the ERCP, an unusual clinical scenario was encountered. Retained extraction basket during ERCP is a rare but known complication and there are no standard recommendations to manage it. To our knowledge, this is the first case report described in the literature with retention of an extraction basket in surgical sutures at ERCP and the longest period from surgery to stone formation in the biliary system. This case report aims to emphasize that in patients with a history of hepatobiliary surgery, postoperative material can cause complications during ERCP.

Pre-Cut Papillotomy Versus Endoscopic Ultrasound-Rendezvous for Difficult Biliary Cannulation: A Systematic Review and Meta-Analysis.

Background: Various endoscopic techniques are employed to achieve biliary cannulation when confronted with difficult biliary access. Every procedure carries its own risk in terms of bleeding, infection, pancreatitis, and cholangitis. Our meta-analysis aimed to compare pre-cut papillotomy and endoscopic ultrasound (EUS)-rendezvous in terms of technical success rates, and post-procedure pancreatitis and bleeding. Methods: We conducted a systematic review and meta-analysis of studies that compared pre-cut papillotomy and EUS-rendezvous. The primary outcome was technical success by achieving biliary cannulation. Secondary outcomes were postoperative pancreatitis and bleeding. A random-effects model was used to calculate the risk ratios (RRs) and confidence intervals (CIs). A P value < 0.05 was considered statistically significant. Results: Our meta-analysis included four studies comparing pre-cut papillotomy and EUS-rendezvous. The studies included 13,659 total endoscopic retrograde cholangiopancreatography (ERCP) procedures, of whom 1,004 patients underwent alternate biliary cannulation procedures due to difficult biliary cannulation. The mean age of the study population was noted to be 49.5 years and males represented 53.3% of the total participants. Both procedures were similar in terms of technical success (RR: 0.95, 95% CI (0.88, 1.02)). No difference was found between rates of post procedure pancreatitis (RR: 1.82, 95% CI (0.80, 4.15)) and post procedure bleeding (RR: 2.80, 95% CI (0.67, 11.66)). Conclusions: There was no difference in technical success of procedure or post-procedure complications such as pancreatitis and bleeding between pre-cut papillotomy and EUS-rendezvous technique. More randomized controlled trials (RCTs) are needed to compare both procedural techniques and complications rates. However, currently, both procedures are equally effective and safe during difficult biliary cannulation in the hands of experienced endoscopists.

Weekend endoscopic retrograde cholangiopancreatography has similar outcomes as weekday procedures-a propensity score match analysis of the Hungarian ERCP Registry.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is essential for the minimally invasive management of biliary and pancreatic disorders. Under certain indications, performing ERCP without delay during the weekend can be important for improving outcomes. Objectives: To compare the outcomes of ERCP performed on weekends and holidays with those of regular weekday ERCPs. Design: Propensity score match analysis of the data from the Hungarian ERCP Registry. Methods: A total of 116 ERCPs were performed during weekends or holidays, and 3144 during weekday working hours. The analyses were performed on 1:2 propensity-matched groups (116 weekend and 232 weekday cases). Results: Weekend ERCPs were mostly performed for acute cholangitis and acute biliary pancreatitis (70% of cases), whereas in the weekday group, only 32% of cases were performed for these indications. No significant difference was found between weekday and weekend ERCPs in terms of the rates of successful (91.38% vs 93.1%, p = 0.565) and difficult (33.62% vs 36.64%, p = 0.511) biliary cannulations. We found no significant differences in the number of adverse events (bleeding, post-ERCP pancreatitis, and 30-day mortality) in ERCPs performed during weekends or weekdays. Moreover, no significant differences in the aforementioned outcomes were detected between the propensity-matched groups. Conclusion: In this propensity-matched study, no significant differences were found in the outcomes of weekend and weekday ERCPs.

Implementing Massive Parallel Sequencing into Biliary Samples Obtained through Endoscopic Retrograde Cholangiopancreatography for Diagnosing Malignant Bile Duct Strictures.

Despite advancements in radiologic, laboratory, and pathological evaluations, differentiating between benign and malignant bile duct strictures remains a diagnostic challenge. Recent developments in massive parallel sequencing (MPS) have introduced new opportunities for early cancer detection and management, but these techniques have not yet been rigorously applied to biliary samples. We prospectively evaluated the Oncomine Comprehensive Assay (OCA) and the Oncomine Pan-Cancer Cell-Free Assay (OPCCFA) using biliary brush cytology and bile fluid obtained via endoscopic retrograde cholangiopancreatography from patients with bile duct strictures. The diagnostic performance of MPS testing was assessed and compared to the pathological findings of biliary brush cytology and primary tissue. Mutations in TP53, BRAF, CTNNB1, SMAD4, and K-/N-RAS identified in biliary brush cytology samples were also detected in the corresponding bile fluid samples from patients with extrahepatic cholangiocarcinoma. These mutations were also identified in the bile fluid samples, but with variant allele frequencies lower than those in the corresponding biliary brush cytology samples. In control patients diagnosed with gallstones, neither the biliary brush cytology samples nor the bile fluid samples showed any pathogenic mutations classified as tier 1 or 2. Our study represents a prospective investigation into the role of MPS-based molecular testing in evaluating bile duct strictures. MPS-based molecular testing shows promise in identifying actionable genomic alterations, potentially enabling the stratification of patients for targeted chemotherapeutic treatments. Future research should focus on integrating OCA and OPCCFA testing, as well as similar MPS-based assays, into existing surveillance and management protocols for patients with bile duct strictures.

Endoscopic ultrasound-guided biliary drainage using electrocautery-enhanced lumen-apposing metal stent for malignant biliary obstruction: A promising procedure.

In this editorial, we comment on the article by Peng et al. Palliative drainage for biliary obstruction resulting from unresectable malignant lesions includes internal and external drainage. The procedures of biliary drainage are usually guided by fluoroscopy or transcutaneous ultrasound, endoscopic ultrasound (EUS), or both. Endoscopic retrograde cholangiopancreatography (ERCP) has been primarily recommended for the management of biliary obstruction, while EUS-guided biliary drainage and percutaneous transhepatic biliary drainage (PTBD) are alternative choices for cases where ERCP has failed or is impossible. PTBD is limited by shortcomings of a higher rate of adverse events, more reinterventions, and severe complications. EUS-guided biliary drainage has a lower rate of adverse events than PTBD. EUS-guided biliary drainage with electrocautery-enhanced lumen-apposing metal stent (ECE-LAMS) enables EUS-guided biliary-enteric anastomosis to be performed in a single step and does not require prior bile duct puncture or a guidewire. The present meta-analysis showed that ECE-LAMS has a high efficacy and safety in relieving biliary obstruction in general, although the results of LAMS depending on the site of biliary obstruction. This study has highlighted the latest advances with a larger sample-based comprehensive analysis.

Comparison of the efficacy and safety of ciprofol and propofol for ERCP anesthesia in older patients: A single-center randomized controlled clinical study.

STUDY OBJECTIVES: Ciprofol is a novel agonist at the gamma-aminobutyric acid-A (GABAA) receptor, exhibiting better cardiovascular stability and rapid recovery. The objective of this study was to compare the efficacy and safety of ciprofol and propofol for endoscopic retrograde cholangiopancreatography (ERCP) anesthesia in older patients. DESIGN: A single-center, randomized, parallel controlled clinical study. SETTING: General Hospital of Northern Theater Command. PATIENTS: We recruited 284 patients and intended to conduct ERCP from November 2021 to June 2022. INTERVENTIONS: Patients scheduled for ERCP were randomly assigned to two groups (n = 142 each): ciprofol group (anesthesia induction 0.3-0.4 mg/kg, anesthesia maintenance 0.8-1.2 mg/kg/h) and propofol group (anesthesia induction 1.5-2.0 mg/kg, anesthesia maintenance 4-12 mg/kg/h). MEASUREMENTS: The primary outcome was sedation success rate, defined as the proportion of patients with successful anesthesia induction. Secondary outcomes encompassed the time of successful induction, the time of complete recovery, the time of leaving the room and the incidence rate of adverse events (hypoxemia, hypotension and injection pain). MAIN RESULTS: The success rate of sedation in both groups was 100 %. The 95 % CI of the difference of sedation success rate was (- 2.63 %, 2.63 %), and the lower limit was greater than the non-inferiority limit of -8 %.The time of successful sedation induction in ciprofol group (38.4 ± 6.5 s) was longer than that in propofol group (30.6 ± 6.2 s, p < 0.05).The time of complete recovery in ciprofol group (12.8 ± 5.8 min) was shorter than that in propofol group (16.9 ± 5.0 min, p < 0.05). The time of leaving the room in ciprofol group (21.8 ± 5.8 min) was shorter than those in propofol group (25.9 ± 5.1 min, p < 0.05). The incidence of injection pain in ciprofol group (2 %) was lower than that in the propofol group (25 %, p < 0.05). Other outcomes didn't show statistical differences. CONCLUSIONS: Compared with propofol, ciprofol exhibited a comparable level of sedation in older patients undergoing ERCP, and recovery was safe and rapid with less injection pain.

Stapfer I and II duodenal perforations after endoscopic procedures: how surgical delay impacts outcomes.

BACKGROUND: Post-endoscopic duodenal perforation is a severe adverse event with high morbidity and mortality rates. Managing this rare event is challenging owing to limited clear guidelines. This retrospective study aimed to examine the relationship between time-to-treatment and morbidity among patients with post-endoscopic duodenal perforations. METHODS: Over 20 years, 78 consecutive patients with post-endoscopic duodenal perforations were analyzed. Among these, most patients underwent endoscopic procedures at the Paoli-Calmettes Institute, whereas some were referred from other centers after a diagnosis of perforation. We described the characteristics of patients who underwent medical treatment alone or interventional procedures. Among patients who underwent interventional management, we compared the outcomes following early or delayed procedures (later than 24 h post-duodenal perforation diagnosis). RESULTS: Overall, 78 patients with post-endoscopic duodenal perforation were identified between September 2003 and September 2022. Of these, 17 (22%) patients underwent non-operative management, and 61 (78%) with peritonitis or adverse clinical features were treated with endoscopic or surgical procedures. Additionally, among these patients, 40 (65%) underwent immediate invasive procedures, surgically (n = 20) or endoscopically (n = 20). Patients with delayed procedures experienced more major Clavien-Dindo ≥ 3 complications and had an increase by 21 of the median comprehensive complication index. Overall, mortality occurred in 7 (8.9%) patients in the entire cohort and in 3 (14.3%) with delayed invasive procedures. CONCLUSIONS: Delayed decision-making is a key factor complicating post-endoscopic duodenal perforation. Therefore, invasive procedures should be performed promptly in cases of adverse conditions requiring additional procedures, ideally within the first 24 h of perforation diagnosis.

Early prediction of post-endoscopic retrograde cholangiopancreatography pancreatitis via dynamic changes of leukocyte: A retrospective study.

BACKGROUND: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) remains a major concern for clinicians. Hence early identification of PEP is meaningful to minimize medical risks. AIMS: This study aims to explore the value of dynamic leukocyte changes for early prediction of PEP. METHODS: Patients from January 2017 to December 2018 (training set) and January 2019 to December 2022 (test set) were retrospectively reviewed. The dynamic changes of leukocyte, neutrophil, and lymphocyte were examined to evaluate the diagnostic value of PEP. RESULTS: A total of 498 patients (36 PEP cases) in training set and 948 patients (71 PEP cases) in test set were analyzed. Four predictors were finally identified in training set containing margin and ratio of 3h-post ERCP leukocyte count (Po Leu) to pre-ERCP leukocyte count (Pr Leu), 3h post-ERCP neutrophil-to-lymphocyte ratio (NLR) and pre-ERCP fibrinogen levels. ROC analysis revealed the optimal thresholds were 2.3 (x109/L), 1.6, 4.8 and 3.1 (g/L), respectively. The sensitivity and specificity of Po Leu - Pr Leu and Po Leu/Pr Leu were 71.0%, 82.7%, 66.1% and 86.3% to diagnosis PEP in patients with hyperamylasemia. CONCLUSIONS: For early identification of PEP, the elevation of amylase and lipase still exhibits the highest sensitivity, while the dynamic changes of leukocyte would be helpful for the different diagnosis of hyperamylasemia.

A case of rare obstructive jaundice induced by concealed displacement of T-tube.

We present the case of a 32-year-old woman who was ultimately diagnosed with obstructive jaundice. She exhibited persist jaundice, liver dysfunction with normal drainage of T-tube (400-500 ml per day), and normal stools. Prior to her admission to our department, she had undergone a cholecystectomy and T-tube placement following common bile duct exploration for cholelithiasis. Although her serum bilirubin levels initially decreased post-surgery, it rose sharply after T-tube cholangiography. The diagnosis remained unclear until we performed endoscopic retrograde cholangiopancreatography (ERCP), which revealed that the obstructive jaundice was induced by improper T-tube placement. There were few such presentations reported before, and it's particularly unusual to encounter jaundice following T-tube placement. Moreover, diagnosing and treating this condition can be challenging when T-tube drainage appears normal. Thus, our case report provides a unique contribution to the literature on obstructive jaundice.
