Although the use of a long metal stent is favored for EUS-guided hepaticogastrostomy (EUS-HGS) for the relief of malignant biliary obstruction (MBO), endoscopic reintervention (E-RI) at the time of recurrent biliary obstruction (RBO) is challenging due to a long intragastric portion. This study evaluated the feasibility and safety of E-RI after a long partially covered metal stent (L-PCMS) placement during EUS-HGS.We performed a multicenter retrospective study between January 2015 and December 2019 examining patients with MBO who underwent E-RI for RBO through the EUS-HGS route after the L-PCMS placement. Technical and clinical success rates, details of E-RI, adverse events (AEs), stent patency, and survival time were evaluated.Thirty-three patients at eight referral centers in Japan who underwent E-RI through the EUS-HGS route were enrolled. The location of MBO was distal in 54.5%. The median intragastric length of the L-PCMS was 5 cm. As the first E-RI attempt, E-RI via the distal end of the existing L-PCMS was successful in 60.6%. The overall technical and clinical success rates of E-RI were 100% and 81.8%, respectively. Liver abscess was noted in one patient. A proximal biliary stricture was associated with the clinical ineffectiveness of E-RI in multivariable analysis (odds ratio, 12.5, P = 0.04). The median survival and stent patency duration after E-RI were 140 and 394 days, respectively.Our study findings suggest that E-RI for RBO after EUS-HGS with a L-PCMS is technically feasible and clinically effective, without any severe AEs, especially for patients with distal MBO.

Drug-induced interstitial lung disease (DI-ILD) is a serious adverse event during chemotherapy. This study aimed to obtain real-world data of the incidence, clinical characteristics, predictive factors, and prognosis of patients with pancreatic cancer who developed DI-ILD.In patients with locally advanced or metastatic pancreatic cancer who underwent standard chemotherapy at our hospital and its participating facilities between April 2014 and March 2019, the clinical features, occurrence rate and clinical course of DI-ILD, and prognosis were retrospectively evaluated.Altogether, 390 patients were finally enrolled. DI-ILD occurred in 24 cases (6.2%). The median period from diagnosis of pancreatic cancer to the onset of DI-ILD was 2.2 months (.6-13.3 months). The rate of DI-ILD onset according to each regimen was 5.8% of gemcitabine (GEM) plus albumin-bound paclitaxel therapy (18/308), 3.8% of GEM (4/106), and 2.3% of FOLFIRINOX (2/88). The incidence of DI-ILD in GEM-based regimens was significantly higher than that in non-GEM-based regimens (p.01). The median overall survival (OS) of the patients with and without DI-ILD after propensity score matching was 11.5 months and 11.4 months (p = .99), respectively. After the resolution of DI-ILD, no statistical significance in the median OS of the patients with and without subsequent treatment (11.0 vs. 6.8 months, p = .18) was observed.DI-ILD is not a rare adverse event in the current standard chemotherapy for pancreatic cancer in Japan. With appropriate management of DI-ILD, the prognosis of patients with DI-ILD can be equivalent to that of patients without DI-ILD.

Although the combination of nanoliposomal irinotecan plus fluorouracil/folinic acid (nal-IRI/FF) exhibited survival benefits in gemcitabine-refractory patients with advanced pancreatic cancer (APC) in the phase III NAPOLI-1 trial, there is limited data on the efficacy and safety of this regimen in real-world settings in Japan. This multicenter, prospective observational study enrolled patients with APC who received nal-IRI/FF after a gemcitabine-based regimen from July 2020 to June 2021. We collected and analyzed clinical data and conducted survival and multivariate analyses. Thirty-one (78%) of the 40 patients had metastases. Nal-IRI/FF was the second-line therapy in 36 patients (90%). The median duration was 3.2 months. The disease control rate was 57%. The median progression-free survival and overall survival (OS) were 4.5 months (95% confidence interval [CI]: 2.8–5.5) and 7.4 months (95% CI: 5.1–10.6), respectively. Common ≥grade 3 toxicities included neutropenia (28%) and fatigue (23%). Fatigue led to treatment discontinuation in 6 out of 10 patients. Multivariate analysis showed that a neutrophil-to-lymphocyte ratio > 4 was a significant risk factor for a short OS (hazard ratio (HR) = 3.08, 95% CI: 1.21–7.85, p = 0.02). In conclusion, nal-IRI/FF is an appropriate treatment option for APC following gemcitabine-containing regimens.

Objectives Percutaneous transhepatic gallbladder drainage (PTGBD) is widely used for patients with acute cholecystitis. There are little data on the efficacy and safety of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) replacement of PTGBD in patients who cannot undergo cholecystectomy. Methods This multicenter retrospective study in Japan reviewed records of patients who underwent EUS-GBD to replace PTGBD between January 2010 and December 2017. Outcomes evaluated included technical success, defined as successful stent placement between the gastrointestinal lumen and the gallbladder; clinical success, defined as subsequent removal of the percutaneous catheter; adverse events; and stent patency. Results EUS-GBD was performed in 21 patients (14 women, mean age 77.5 ± 8.0 years) to replace PTGBD that had been instituted for acute cholecystitis (n = 19) or obstructive jaundice (n = 2). Technical success was achieved in 19 (90.5%). The median period from PTGBD placement to EUS-GBD was 11 days (range, 6-68 days). The mean procedure time was 19.5 ± 5.1 min. No early adverse events were observed. There were three late adverse events, distal stent migration in two cases and stent occlusion causing recurrent cholecystitis in one patient. Reintervention was required in two patients. The percutaneous catheter was removed after EUS-GBD in 17 patients at a median of 7 days (range, 2-20 days). The duration of stent patency was 139 days (range, 8-664 days). Conclusions Where ongoing gallbladder drainage is required, conversion from PTGBD to EUS-GBD is a feasible, effective, and safe technique for patients who cannot undergo cholecystectomy.
