RESUMEN
INTRODUCTION: This retrospective study investigated the efficacy and safety of nano-liposomal irinotecan (nal-IRI) plus 5-fluorouracil/L-leucovorin (5-FU/l-LV) treatment in the second-line or later setting for advanced pancreatic cancer under real-world conditions. METHODS: Between June 2020 and September 2021, a total of 44 patients with unresectable advanced pancreatic cancer treated with nal-IRI + 5-FU/l-LV in our affiliated hospitals were included. The prognosis, predictive factors (including systemic inflammation-based prognostic indicators), and adverse events were investigated. RESULTS: The median age was 68 (interquartile range 62-73) years old, and 22 patients (50.0%) were male. Concerning tumor factors, 9 patients (20.5%) had local advanced disease and 35 patients (79.5%) had metastases. Twenty-five of the 44 patients were receiving second-line treatment, and 19 were receiving third-line or later treatment. The median overall survival (OS) and progression-free survival were 9.0 (range, 0.7-15.4) months and 4.4 (range, 0.6-15.4) months, respectively. The overall response rate was 5.3%. The disease control rate was 44.7%. Patients with a neutrophil-to-lymphocyte ratio of ≥2.7 had a significant risk of a poor OS (HR = 0.275, p = 0.017). Adverse events were manageable, although gastrointestinal symptoms and neutropenia were observed. The most common grade ≥3 adverse event was neutropenia, which was reported in 20% of patients. CONCLUSIONS: Nal-IRI + 5-FU/l-LV therapy was considered to be a useful regimen as second-line or later treatment for unresectable advanced pancreatic cancer, even in clinical practice.

INTRODUCTION: A few reports stating that differences in the various types of contrast media injected into the pancreatic duct are related to the onset of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) have been published, and it was indicated that iodixanol which is a nonionic iodide radiographic contrast medium with a dimeric (2 dimers) structure may reduce the incidence of PEP. The aim of this retrospective study is to evaluate the usefulness of iodaxanol for prevention PEP in comparison with megulamine amidototrizoate. METHODS: Two hundred and ninety-one patients were enrolled and divided into the 2 groups according to the contrast medium used. One hundred and fifty-five patients underwent ERCP with meglumine amidotrizoate, and 136 patients underwent ERCP with iodaxanol. The primary outcome of this study was the incidence of PEP associated with the use of each contrast medium. RESULTS: In this study, comparison of the meglumine amidotrizoate treatment and iodaxanol treatment groups showed no significant difference with respect to the incidence of PEP. In addition, there was also no difference between the groups with respect to PEP severity. CONCLUSION: Our study suggested that iodaxanol does not necessarily contribute to the prevention of PEP in comparison with meglumine amidotrizoate.

Endoscopic ultrasound-guided fine-needle aspiration has become the common procedure for the diagnosis of pancreatic mass, and cytological examination is usually the first approach. Solid pseudopapillary neoplasm (SPN) cytologically represents papillary structures of branching capillaries surrounded by discohesive neoplastic cells. However, it may present various degrees of tissue degeneration, causing diagnostic challenges. Here, we report a 21-year-old female who had a 2-cm-sized mass in the pancreas head. Cytological examination revealed clumps of small round/oval cells that represented microcystic configurations with mucus, mimicking adenoid cystic carcinoma or mucinous adenocarcinoma. Cercariform cells, nuclear grooves/folding, and cytoplasmic vacuoles were not observed. Histopathological examination revealed confluent small glandular structures containing acidic mucus. The tumor cells were positively stained for ß-catenin, CD10, and CD56, and negative for chromogranin A and E-cadherin, suggesting SPN, micropseudocystic variant. This variant has been scarcely described, but we should recognize it for accurate cytological triage of pancreatic tumors.

Objective Endoscopic gallbladder stenting (EGBS) is an alternative treatment option for high-risk surgical patients with acute cholecystitis. However, there are no reports focusing on EGBS in patients with concomitant unresectable cancer. The aim of this study was thus to evaluate EGBS in such patients. Methods Twenty-two consecutive patients with acute cholecystitis and unresectable cancer were enrolled between September 2010 and December 2014. Their median age was 74.5 years (range: 51-95). Thirteen patients were men and nine were women. The primary cancers of the patients were biliary tract cancer (9), pancreas cancer (9), lung cancer (2), gastric cancer (1), and colon cancer (1). The causes of cholecystitis were calculus cholecystitis (7), obstruction by malignant tumor (13), and obstruction by fully covered stent (2). Results EGBS was successfully performed in 17 patients (77.2%). The technical success rates for calculus cholecystitis, obstruction by malignant tumor, and obstruction by fully covered stent were 85.7% (6/7), 69.2% (9/13), and 100% (2/2), respectively. No complications were observed. Percutaneous transhepatic gallbladder drainage was conducted on two patients in whom EGBS had failed and then we performed EGBS by a rendezvous approach. Of the 19 patients in whom we finally deployed EGBS, the median follow-up period was 229 days (range: 14-880 days). A recurrence of acute cholecystitis occurred in three (15.7%) patients 14, 130, and 440 days after EGBS placement. The rates of recurrence of cholecystitis at one and two years were 10.5% and 18.7%, respectively. Conclusion Our study demonstrated that EGBS is a safe and effective method for acute cholecystitis in patients with concomitant unresectable cancer.

AIM: To investigate the efficacy and outcomes of endoscopic papillary large balloon dilation (EPLBD) for bile duct stones in a multicenter prospective study. METHODS: Lithotomy by EPLBD was conducted in 124 patients with bile duct stones ≥ 13 mm in size or with three or more bile duct stones ≥ 10 mm. After endoscopic sphincterotomy, the papilla was dilated using balloons 12-20 mm in diameter fitting the bile duct diameter. RESULTS: The success rate of first-time lithotomy was 86.3% (107/124) and the final lithotomy success rate was 100% (124/124). Lithotripsy was needed in 10 of the 124 (13.6%) patients. Adverse events due to the treatment procedure occurred in 6 (4.8%) patients, all of which were mild. Performing large balloon dilation after endoscopic sphincterotomy in patients with large stones or multiple stones in the bile duct is considered to ensure the safety of treatment and to reduce the need for lithotripsy. CONCLUSION: It is suggested that treatment by EPLBD for large bile duct stones may be safe and useful.
