Abstract Background Selective deep biliary cannulation is the first and the most important step before further biliary therapy. Transpancreatic sphincterotomy(TPS), and needle knife fistulotomy(NKF) were commonly used in patients with difficult cannulation, but few studies compare the outcome between TPS and NKF.Methods A total of 78 patients who met the criteria of difficult cannulation in the National Taiwan University hospital from October 2015 to October 2017 were retrospectively reviewed. Their baseline demographics, success rate of biliary cannulation, and the rate of adverse events were assessed.Results 31 patients and 47 patients underwent TPS and NKF for difficult biliary access, respectively. The characteristics of the 2 groups were similar, but patients in TPS group had more frequent pancreatic duct cannulation. Bile duct cannulation was successful in 23 patients (74.2 %) in the TPS group and 39 (83.0%) in the NKF group (P=0.34). There was no difference between the TPS and NKF in the rate of adverse events, including post-ERCP pancreatitis (PEP) (16.1% vs. 6.4%, p = 0.17), and hemorrhage (3.2% vs. 8.5%, p = 0.35). No perforation occurred.Conclusions Both TPS and NKF have good biliary access rate in patient with difficult cannulation. TPS has acceptable successful rate and similar complication rate, compared with NKF.

Background. Transpancreatic precut sphincterotomy (TPS) is an option for difficult common bile duct (CBD) access, and the reports are few, with immediate success rate varying from 60 to 96%. The description of relation between the size of TPS and the immediate success rate of CBD cannulation was not found in the literature. The Aim of the Study. To evaluate the relation of large TPS to immediate success rate of CBD cannulation. Methods. A retrospective analysis was performed in prospectively collected data of 20 patients. TPS was performed with traction papillotome in the main pancreatic duct (MPD) directing towards 11 o’clock. Needle knife (NK) was used to enlarge TPS in five patients, and the other 15 cases had large TPS from the beginning of sphincterotomy. Prophylactic pancreatic stent was inserted in 18 cases, with diclofenac given in 12 cases. Results. The immediate success rate of CBD cannulation was 90% and with an eventual success rate of 100%. The failure in one immediate CBD cannulation with large TPS was due to atypical location of CBD orifice, and the other failed immediate CBD cannulation was due to inadequate size of TPS. Complications included 3 cases of post-TPS bleeding and 3 cases of mild pancreatitis. Conclusion. TPS is an effective procedure in patients with difficult biliary access and can have high immediate success rate with large TPS.

ABSTRACT BACKGROUND: A successful bile duct cannulation is a prerequisite for the realization of endoscopic retrograde cholangiopancreatography (ERCP). When biliary cannulation is not possible, needle-knife fistulotomy (NKF) can be performed. However, when biliary access is not successfully achieved even after performing NKF, it is possible to interrupt the procedure, and repeat the ERCP after a short interval. OBJECTIVE: The aim of this study is to analyze if repeating an ERCP after a short interval of 48 hours is effective in achieving biliary access after an initial NKF was unsuccessfully performed. METHODS: A total of 1024 patients with a naive papilla, that underwent ERCP between the years of 2009-2019, were retrospectively reviewed. Difficult biliary cannulation was identified in 238 of these cases and NKF was performed. Success of biliary cannulation, NKF success at the first and second ERCPs, the associations between the type of the papilla, biliary dilatation, and overall success of NKF and adverse events rates were evaluated. RESULTS: Biliary access was initially achieved in 183 (76.8%) cases. Of the 55 (23.1%) remaining cases a second attempt was performed after 48 hours, and biliary access was successfully achieved in 46 (83.6%) of them. The overall success of NKF after the first and second ERCP, the success rate was 96.2%. Papilla located out of its normal position was related to a minor chance of success at NKF (P<0.05). CONCLUSION: We conclude that when biliary access is not achieved after the performance of a NKF, a second attempt is safe and effective and should be attempted.

Background: In the setting of a naïve papilla, biliary cannulation is a key step in successfully performing endoscopic retrograde cholangiography (ERC). Difficult biliary cannulation (DBC) is associated with an increased risk of post-ERCP-pancreatitis and failure of the whole procedure. Summary: Recommendations for biliary cannulation can be divided in (a) measures to reduce the likelihood of a difficult papilla-situation a priori and (b) rescue techniques in case the endoscopist is actually facing DBC. (a): careful inspection of the papillary anatomy and optimizing its accessibility by scope-positioning is fundamental. A sphincterotome in combination with a soft-tip hydrophilic guide-wire rather than a standard catheter with a standard guide-wire should be used. (b): The most important rescue techniques are needle-knife precut, double-guidewire technique and transpancreatic sphincterotomy. In few cases, anterograde techniques are needed. To this regard, the EUS-guided biliary drainage (EUS-BD) followed by rendezvous is increasingly used as an alternative to percutaneous-transhepatic biliary drainage. Key Messages: Biliary cannulation can be accomplished with alternative retrograde or less frequently by salvage-anterograde techniques, once conventional direct cannulation attempts have failed. Considering recent favorable data for the early use of transpancreatic sphincterotomy, an adopted version of the 2016 European-Society-for-Gastrointestinal-Endoscopy (ESGE)-algorithm on biliary cannulation is proposed.

Abstract Background Immune checkpoint inhibitors have been approved for various types of cancer; however, they cause a broad spectrum of immune-related adverse events (irAEs). The association between the development of irAEs and the clinical benefit remains uncertain. We aimed to evaluate the association of irAEs and the treatment efficacy in the real-world practice. Methods We conducted a retrospective study on patients with recurrent or metastatic non-small cell lung cancer, melanoma, renal cell carcinoma, or gastric cancer who received anti-PD-1/PD-L1 antibodies (nivolumab, pembrolizumab, or atezolizumab) at the Keio University Hospital between September 2014 and January 2019. We recorded treatment-related AEs from medical records and graded them using the Common Terminology Criteria for Adverse Events version 4. We performed an overall survival (OS) analysis using a Cox proportional hazards model. Results Among 212 patients eligible for this study, 108 experienced irAEs and 42 developed multiple irAEs. OS in patients with multiple irAEs was significantly longer than that in patients with single irAE (42.3 months vs. 18.8 months; hazard ratio [HR], 0.48; 95% confidence interval [CI], 0.25–0.93; P = 0.03). Moreover, OS from the development of a second irAE in those with multiple irAEs was longer than that from the development of the first irAE in patients with single irAEs (median OS, 26.9 months vs. 17.7 months, respectively; HR, 0.59; 95% CI, 0.30–1.14; P = 0.11). Conclusions Our single-center retrospective study revealed a remarkable tendency associating the development of multiple irAEs with favorable prognoses.
