Introduction: Wire-guided cannulation (WGC) during endoscopic retrograde cholangiopancreatography (ERCP) is a selective biliary cannulation technique aimed at improving the successful selective biliary cannulation rate and reducing the rate of post-ERCP pancreatitis (PEP) incidence. This study aimed to evaluate the effectiveness of angled-tip guidewires (AGW) vs. straight-tip guidewires (SGW) for biliary cannulation via WGC by a trainee. Methods: We conducted a prospective, single-center, open-labeled, randomized, and controlled trial. Fifty-seven patients were enrolled in this study and assigned randomly to two groups (Group A to S and Group S to A). In this study, we started selective biliary cannulation via WGC with an AGW or an SGW for 7 min. If cannulation was unsuccessful, the other guidewire was used, and cannulation was continued for another 7 min (cross-over method). Results: The selective biliary cannulation success rate over 14 min was significantly higher with an AGW compared with an SGW over 14 min (57.8% vs. 34.3%, p = 0.04) and for the second 7-min segment (36.4% vs. 0%, p = 0.04). No significant difference was found for adverse events such as pancreatitis between the two guidewires. Conclusions: Our results suggest that an AGW is recommended for WGC performed by a trainee.

Background: It is critical for every pancreatic surgeon to determine how to protect the aberrant hepatic artery intraoperatively in order to safely implement laparoscopic pancreatoduodenectomy (LPD). “Artery-first” approaches to LPD are ideal procedures in selected patients with pancreatic head tumors. Here, we described our surgical procedure and experience of aberrant hepatic arterial anatomy-LPD (AHAA-LPD) in a retrospective case series. In this study, we also sought to confirm the implications of the combined SMA-first approach on the perioperative and oncologic outcomes of AHAA-LPD. Methods: From January 2021 to April 2022, the authors completed a total of 106 LPDs, of which 24 patients underwent AHAA-LPD. We evaluated the courses of the hepatic artery via preoperative multi-detector computed tomography (MDCT) and classified several meaningful AHAAs. The clinical data of 106 patients who underwent AHAA-LPD and standard LPD were retrospectively analyzed. We compared the technical and oncological outcomes of the combined SMA-first approach, AHAA-LPD, and the concurrent standard LPD. Results: All the operations were successful. The combined SMA-first approaches were used by the authors to manage 24 resectable AHAA-LPD patients. The mean age of the patients was 58.1 ± 12.1 years; the mean operation time was 362 ± 60.43 min (325–510 min); blood loss was 256 ± 55.72 mL (210–350 mL); the postoperation ALT and AST were 235 ± 25.65 IU/L (184–276 IU/L) and 180 ± 34.43 IU/L (133–245 IU/L); the median postoperative length of stay was 17 days (13.0–26.0 days); the R0 resection rate was 100%. There were no cases of open conversion. The pathology showed free surgical margins. The mean number of dissected lymph nodes was 18 ± 3.5 (14–25); the number of tumor-free margins was 3.43 ± 0.78 mm (2.7–4.3 mm). There were no Clavien–Dindo III–IV classifications or C-grade pancreatic fistulas. The number of lymph node resections was greater in the AHAA-LPD group (18 vs. 15, p < 0.001). Surgical variables (OT) or postoperative complications (POPF, DGE, BL, and PH) showed no significant statistical differences in both groups. Conclusions: In performing AHAA-LPD, the combined SMA-first approach for the periadventitial dissection of the distinct aberrant hepatic artery to avoid hepatic artery injury is feasible and safe when performed by a team experienced in minimally invasive pancreatic surgery. The safety and efficacy of this technique need to be confirmed in large-scale-sized, multicenter, prospective randomized controlled studies in the future. Full article

(1) Background: Abnormal liver function tests are commonly encountered in clinical practice, often leading to additional workup to determine the underlying etiology of these abnormal laboratory studies. As part of this evaluation, if less invasive imaging studies are performed and are without evidence of biliary obstruction, liver biopsy may be performed, and the finding of large duct obstruction on liver biopsy is commonly encountered. The utility of endoscopic retrograde cholangiopancreatography (ERCP) for evaluation and management of possible biliary obstruction in patients with large duct obstruction on liver biopsy has not been studied to date. (2) Methods: To assess the utility of ERCP in patients with large bile duct obstruction on liver biopsy, we retrospectively evaluated patients with large duct obstruction on liver biopsy from 2010–2019 at our tertiary care and transplant center. Demographic and clinical characteristics were evaluated for all patients, with sub-group analysis for patients who underwent ERCP and those who had intervenable findings at the time of ERCP. Descriptive statistics with proportions, means, and standard deviations were performed for demographics and clinical variables using absolute standardized difference. (3) Results: During the study period, 189 liver biopsies with evidence of large duct obstruction were performed. After exclusion criteria were applied, 166 unique patients were eligible for the study. Ninety-one patients with evidence of large duct obstruction on liver biopsy underwent ERCP and 75 did not. Of the 91 patients who underwent ERCP, 76 patients (84%) had an intervenable finding at ERCP. Patients who underwent ERCP were overall more likely to have had a liver transplant (65% ASD 0.63), have previously undergone cholecystectomy (80%, ASD 0.56), and be immunocompromised (80%, ASD 0.56). (4) Conclusions: ERCP is high yield when large duct obstruction is apparent on liver biopsy, with the majority of patients (84%) who undergo ERCP in this clinical context having a biliary finding necessitating therapeutic endoscopic intervention.

Background and aim: Pancreato-biliary patients who undergo endoscopic procedures have high potential risk of delirium. Although benzodiazepine has traditionally been used to treat insomnia, this drug might increase delirium. Lemborexant may be useful for patients with insomnia, without worsening delirium, although there is no evidence for high-risk patients with pancreato-biliary disease. The aim of this pilot study was to evaluate the safety and efficacy of lemborexant for insomnia and the frequency of delirium after endoscopic procedures under deep sedation in patients with pancreato-biliary disease. Method: This retrospective study included consecutive patients who were administered lemborexant after endoscopic procedures for pancreato-biliary disease between September 2020 and June 2022. The primary outcome of this study was evaluation of the safety and efficacy of lemborexant for insomnia. Frequency of delirium was the secondary outcome. Result: In total, 64 patients who had the complication of insomnia after an endoscopic procedure were included in the study. Risk factors for delirium were advanced age (n = 36, 56.3%), dementia (n = 10, 15.6%), and regular alcohol use (n = 13, 20.3%), as well as the sedatives midazolam and pentazocine that were administered to all patients at the time of the endoscopic procedure. Successful asleep was achieved by 61/64 patients (95.3%). No fall event was observed during the night following the procedure in any patient. However, mild consciousness transformation was observed in one patient. Conclusions: In conclusion, lemborexant use may be effective and safe for use after endoscopic procedures in pancreato-biliary patients, without increasing the risk of delirium. Full article

Background: Both endoscopic nasogallbladder drainage (ENGBD) and endoscopic gallbladder stenting (EGBS) are effective management for acute cholecystitis, although ENGBD can cause discomfort due to its nature of external drainage. Converting ENGBD to EGBS after improvement of cholecystitis might be one treatment strategy. The drainage tube of ENGBD could be endoscopically cut inside the stomach to convert to internal drainage without additional endoscopic retrograde cholangiography (ERCP). Aims: To evaluate the feasibility, efficacy and safety of endoscopic internalization by cutting an ENGBD tube for acute cholecystitis. Methods: Twenty-one patients who underwent endoscopic internalization by cutting the ENGBD tube were enrolled in this study. We initially placed an ENGBD tube for gallbladder lavage and continuous drainage. After improvement of cholecystitis, the tube was cut in the stomach by esophagogastroduodenoscopy (EGD) and placed as EGBS until surgery. Results: The technical success rate of this procedure was 90.5% (19/21), and the clinical success rate was 100% (19/19). The median procedural time was 5 min (range: 2–14 min). Procedural-related adverse events (AEs) were observed in two patients where the tip of the ENGBD tube migrated into the common bile duct from the gallbladder during the procedure in both. During the waiting period for elective surgery, no AEs were identified, except for stent migration without symptoms in one patient (4.7%). Conclusion: Endoscopic internalization by cutting the ENGBD tube after improvement of cholecystitis could be an effective and safe treatment option for preventing recurrent cholecystitis in the waiting period until cholecystectomy.

Background: Malignant afferent loop obstruction (ALO) is rare condition and is difficult to manage. Endoscopic transluminal treatment has become easier with the advent of balloon-assisted enteroscopes with a large working channels and self-expandable metal stent (SEMS) with a 9 Fr delivery system. Methods: From July 2016 to March 2022, 22 patients with symptomatic malignant ALO who underwent endoscopic transluminal treatment (Initial cohort), of which 18 patients received endoscopic transluminal SEMS placement (SEMS cohort), were retrospectively evaluated. We evaluated outcomes of endoscopic transluminal treatment and long-term outcomes of SEMS placement for malignant ALO. Results: In the Initial cohort, technical and clinical success rates were both 95.5%. The median procedural time was 28.0 min. One case of guidewire-induced micro-perforation occurred as an early complication (4.5%). In the SEMS cohort, and no early complication was observed. Recurrent obstruction occurred in two cases (11.1%) during the follow-up period (median: 102 days). One was managed by additional SEMS placement and the other was treated conservatively. Conclusions: High technical and clinical success was achieved by endoscopic transluminal treatment with short procedural time for malignant ALO. Endoscopic SEMS placement also appears to be safe and effective, and additional SEMS placement can be considered in cases of re-obstruction. Full article

Background/Aims: Endoscopic management by endoscopic sphincterotomy with or without plastic stents or fully covered self-expandable metallic stents (FCSEMSs) is widely accepted as the current standard of care for postoperative bile leaks. Biliary stents are placed across the papilla, not above the papilla. We investigated the safety and effectiveness of the bridge-and-seal technique for bile leaks by the placement of FCSEMS above the papilla. Methods: This was a retrospective study of FCSEMS placement above the papilla for bile leaks between October 2016 and July 2021. FCSEMS was placed above the papilla to bridge and seal the leak. The main outcome measures were the resolution of bile leaks and adverse events. Results: Seven patients with postoperative bile leaks underwent FCSEMS above the papilla. The locations of bile leaks were 1 cystic duct remnant; 2 intrahepatic bile duct; 1 hepatic duct; 2 common bile duct and 1 anastomosis. The technical success rate of FCSEMS placement was 100%, and resolution of bile leaks was achieved in five patients (71.4%). All the adverse events were observed after FCSEMS removal; as follows: 1 moderate cholangitis; 2 mild post-ERCP pancreatitis; and 1 mild remnant cholecystitis. Conclusions: FCSEMS placement above the papilla can be a treatment option for postoperative bile leaks. Full article

Pancreatic necroses are a major challenge in the treatment of patients with pancreatitis, causing high morbidity. When indicated, these lesions are usually drained endoscopically using plastic or metal stents. However, data on factors associated with the occurrence of failure or adverse events during stent therapy are scarce. We retrospectively analyzed all adverse events and their associated features which occurred in patients who underwent a first-time endoscopic drainage of pancreatic necrosis from 2009 to 2019. During the observation period, a total of 89 eligible cases were identified. Adverse events occurred in 58.4% of the cases, of which 76.9% were minor (e.g., stent dislocation, residual lesions, or stent obstruction). However, these events triggered repeated interventions (63.5% vs. 0%, p < 0.001) and prolonged hospital stays (21.0 [11.8–63.0] vs. 14.0 [7.0–31.0], p = 0.003) compared to controls without any adverse event. Important factors associated with the occurrence of adverse events during endoscopic drainage therapy were positive necrosis cultures (6.1 [2.3–16.1], OR [95% CI], p < 0.001) and a larger diameter of the treated lesion (1.3 [1.1–1.5], p < 0.001). Superinfection of pancreatic necrosis is the most significant factor increasing the likelihood of adverse events during endoscopic drainage. Therefore, control of infection is crucial for successful drainage therapy, and future studies need to consider superinfection of pancreatic necrosis as a possible confounding factor when comparing different therapeutic modalities.

Prophylactic pancreatic stenting effectively reduces the rate and severity of post-ERCP pancreatitis (PEP) in the precut technique; however, studies on the optimal type and duration of the stent are still lacking. This prospective study evaluated the incidence and severity of PEP and the rate of spontaneous stent dislodgement in patients undergoing transpancreatic precut sphincterotomy (TPS) accompanied by prophylactic pancreatic stenting with an unflanged plastic stent (4F × 5 cm) for difficult biliary cannulation. A total of 247 patients with naïve papilla were enrolled in this study, and data were collected prospectively. In the final analysis, 170 and 61 patients were included in the standard cannulation technique and TPS groups, respectively. The incidence of PEP in the standard cannulation technique and TPS groups was 3.5% and 1.6% (p = 0.679), respectively. The technical success rate of selective biliary cannulation in the TPS group was 91.8%. The spontaneous dislodgement rate of the prophylactic plastic stent was 98.4%. In conclusion, an unflanged pancreatic stent (4F × 5 cm) placement in TPS for patients with failed standard cannulation technique is a safe and effective measure due to low adverse events and few additional endoscopic procedures for removing the pancreatic duct (PD) stent.

Background and Purpose: During endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), tract dilation is one of the most important steps, and the placement of conventional metal stents with 8.5 Fr delivery devices is difficult due to the large outer shape of the device. Fine-gauge balloon catheters have become popular because of their stricture penetration ability and ease of dilation. This study aimed to evaluate the utility of fine-gauge balloon catheters. Patients and Methods: This retrospective study involved 38 patients who underwent conventional metal stent placement. The patients were classified into two groups: those who underwent dilation with a fine-gauge balloon catheter before initial metal stenting (balloon dilation group) and those who underwent bougie dilation only (non-balloon dilation group). We evaluated the stenting success rate after initial dilation and adverse events. Results: Seventeen and twenty-one patients were included in the balloon dilation and non-balloon dilation groups, respectively. The stenting success rate after initial dilation was 100% (17/17) in the balloon dilation group and 71.4% (15/21) in the non-balloon dilation group (p = 0.024). As adverse events, peritonitis was observed in one case (4.8%) in the balloon dilation group, and in three cases (14.3%) in the non-balloon dilation group (p = 0.613). Conclusions: Dilation using a fine-gauge balloon catheter before conventional metal stent with 8.5 Fr delivery device placement is considered effective in EUS-HGS. Full article

Background and study aims: Endoscopic biliary stent placement is a minimally invasive intervention for patients with biliary strictures. Stent patency and function time are crucial factors. Suprapapillary versus transpapillary stent positioning may contribute to stent function time, so a meta-analysis was performed in this comparison. Methods: A comprehensive literature search was conducted in the CENTRAL, Embase, and MEDLINE databases to find data on suprapapillary stent placement compared to the transpapillary method via endoscopic retrograde cholangiopancreatography in cases of biliary stenosis of any etiology and any stent type until December 2020. We carried out a meta-analysis focusing on the following outcomes: stent patency, stent migration, rate of cholangitis and pancreatitis, and other reported complications. Results: Three prospective and ten retrospective studies involving 1028 patients were included. Suprapapillary stent placement appeared to be superior to transpapillary stent positioning in patency (weighted mean difference = 50.23 days, 95% CI: 8.56, 91.98; p = 0.0.018). In a subgroup analysis of malignant indications, suprapapillary positioning showed a lower rate of cholangitis (OR: 0.34, 95% CI: 0.13, 0.93; p = 0.036). Another subgroup analysis investigating metal stents in a suprapapillary position resulted in a lower rate of pancreatitis (OR: 0.16, 95% CI: 0.03, 0.95; p = 0.043) compared to transpapillary stent placement. There was no difference in stent migration rates between the two groups (OR: 0.67, 95% CI: 0.17, 2.72; p = 0.577). Conclusions: Based on our results, suprapapillary biliary stenting has longer stent patency. Moreover, the stent migration rate did not differ between the suprapapillary and transpapillary groups.

Direct endoscopic necrosectomy (DEN) using a lumen-apposing metal stent (LAMS) is a standard therapy for the management of symptomatic walled-off necrosis (WON). Here, we demonstrated the efficacy of the routine placement of long plastic stents after a DEN session to treat laterally extended WON. Patients (n = 6) with symptomatic laterally extended WON who underwent DEN after long plastic stent placement were included. The primary endpoint was clinical efficacy of the procedure. The technical and clinical success rates were 100% without major adverse events. The WON extended to the pelvic cavity or pericolic area, and the WON size was between 18.6 and 35.8 cm in length. The median number of DEN sessions was 10 (range 6–16), and two or three long plastic stents were placed after every DEN session. Only one patient suffered from pneumoperitoneum during DEN, which spontaneously resolved within 20 min. Placement of a long plastic stent after DEN using LAMS is a minimally invasive and effective treatment for symptomatic laterally extended WON. Further studies are needed to define the indications and most suitable patients. Full article
