Endoscopic drainage for pancreatic and peripancreatic fluid collections (PFCs) has been increasingly used as a minimally invasive alternative to surgical or percutaneous drainage. Recently, endoscopic ultrasound-guided transluminal drainage (EUS-TD) has become the standard of care and a safe procedure for nonsurgical PFC treatment. EUS-TD ensures a safe puncture, avoiding intervening blood vessels. Single or multiple plastic stents (combined with a nasocystic catheter) were used for the treatment of PFCs for EUS-TD. More recently, the use of covered self-expandable metallic stents (CSEMSs) has provided a safer and more efficient approach route for internal drainage. We focused our review on the best approach and stent to use in endoscopic drainage for PFCs. We reviewed studies of EUS-TD for PFCs based on the original Atlanta Classification, including case reports, case series, and previous review articles. Data on clinical outcomes and adverse events were collected retrospectively. A total of 93 patients underwent EUS-TD of pancreatic pseudocysts using CSEMSs. The treatment success and adverse event rates were 94.6% and 21.1%, respectively. The majority of complications were of mild severity and resolved with conservative therapy. A total of 56 patients underwent EUS-TD using CSEMSs for pancreatic abscesses or infected walled-off necroses. The treatment success and adverse event rates were 87.8% and 9.5%, respectively. EUS-TD can be performed safely and efficiently for PFC treatment. Larger diameter CSEMSs without additional fistula tract dilation for the passage of a standard scope are needed to access and drain for PFCs with solid debris.

Nosocomial infection management is one of the most important subjects in terms of risk management in a hospital. To achieve the nosocomial infection management appropriately, both public relations and information gathering are important. When it comes to publicity, it is desirable that information is offered quickly and efficiently and the personnel are able to access the information easily anytime and wherever they are. As for information gathering, it is also important to collect the information concerning the nosocomial infection promptly, and to tell it quickly to infection management persons including infection control team members. The infection control committee of our hospital has engaged in both publicity and information gathering by using the committee web site established in the LAN of the hospital since January 2004. The web site carries notifications, organization chart, list of committee members, various manuals, guidance of educational activities, infection management, etc. It is also used for questions and answers, and gathering information concerning nosocomial infection. The number of times the web site was accessed was about 200 every month, and was considerable at night and on holidays. This method of using the web site seems to be useful to promote nosocomial infection management.

X-linked inhibitor of apoptosis (XIAP) deficiency is a rare primary immunodeficiency and gastrointestinal (GI) lesions in XIAP deficiency are similar to Crohn’s disease. For patients with Crohn’s disease, endoscopic balloon dilation (EBD) is known to be a standard procedure for intestinal strictures including upper GI tract. However, there are no articles which mention the efficacy of EBDs for the strictures in upper GI tract in patients with XIAP deficiency. Herein, we describe an 18-year-old male with XIAP deficiency in whom EBDs for the rectum, ileocecal valve (ICV), and duodenum were performed. Before hematopoietic stem cell transplantation (HSCT), GI endoscopy revealed strictures of the rectum, ICV and duodenum with active ulcers. Although these ulcers healed after HSCT, the strictures progressed. Therefore, we performed EBDs for the strictures of the rectum, ICV, and duodenum. In contrast studies, we did not find any other strictures in the small intestine. Throughout the patient’s clinical course, no complications of EBD occurred. He started eating after EBDs, but abdominal symptoms did not relapse without any dietary restrictions. Our case suggests that EBD could be an effective and safe procedure for intestinal strictures including upper GI tract after HSCT in patients with XIAP deficiency.

A 72-year-old man with jaundice by ampullary adenocarcinoma was treated at our hospital. For biliary decompression, a transpapillary, fully covered, self-expandable metal stent (FCSEMS) was deployed. Four days later, the patient developed acute cholangitis. Endoscopic carbon dioxide cholangiography revealed kinking of the common bile duct above the proximal end of the FCSEMS. A 7-F double-pigtail plastic stent was therefore placed through the FCSEMS to correct the kink, straightening the common bile duct (CBD) and improving cholangitis. This is the first report of a unique use of a double-pigtail plastic stent to correct CBD kinking. The placement of a double-pigtail plastic stent can correct CBD kinking, without requiring replacement or addition of a FCSEMS, and can lead to cost savings.

PURPOSE: The International Organization for Standardization-5fluorouracil (FU) 10 trial found that bolus 5-FU and l-leucovorin was not inferior to S-1 in the treatment of gastric cancer (GC). Continuous 5-FU and the rapid injection of 5-FU have different anti-cancer effects. Thus, bolus 5-FU and l-leucovorin treatment might be useful for oral FU-resistant GC. MATERIALS AND METHODS: We retrospectively analyzed the medical records of all patients with S-1 or capecitabine-resistant, unresectable, or recurrent GC treated with bolus 5-FU and l-leucovorin between January 2010 and December 2015 at Hokkaido University Hospital. The bolus 5-FU and l-leucovorin regimen consisted of intravenous l-leucovorin (250 mg/m²/2 h) and bolus 5-FU (600 mg/m²) administered once weekly followed by a 2-week rest period; each cycle was repeated every 8 weeks. RESULTS: A total of 14 patients were identified. The disease control rate was 35.7%. The median progression-free survival was 1.6 months (95% confidence interval [CI], 1.3~2.0 months), and the median overall survival was 6.3 months (95% CI, 4.7~7.9 months). No patient died from treatment-related causes. The most common severe adverse event associated with bolus 5-FU and l-leucovorin was neutropenia, which occurred in 21.4% of patients. CONCLUSIONS: Bolus 5-FU and l-leucovorin treatment might be useful for oral FU-resistant GC. We are planning a multi-center prospective phase II trial to evaluate the efficacy and safety of bolus 5-FU and l-leucovorin treatment for pre-treated unresectable or recurrent GC to confirm the results of this limited, retrospective study.

A 69-year-old woman with jaundice was referred to our hospital. After a final diagnosis of pancreatic cancer with liver metastasis, we performed transpapillary biliary drainage with a covered self-expandable metal stent (SEMS). Three months later, we also placed an uncovered duodenal stent for duodenal stricture in a side-to-end fashion. Another month later, for biliary SEMS obstruction, we attempted a transpapillary approach. A duodenoscope was advanced and a guidewire was passed through the mesh of the duodenal stent into the bile duct with a flexible tip catheter, but the catheter was not. Thus, we exchanged the duodenoscope for a forward-viewing two-channel endoscope and used the left working channel with a flexible tip catheter. By adjusting the axis, we finally succeeded biliary cannulation and accomplished balloon cleaning for recanalization of the SEMS. This is the first case with successful biliary cannulation by combined use of a two-channel endoscope and a flexible tip catheter.

Background/Aims:
Transabdominal ultrasonography (US) helps evaluate Crohn’s disease (CD) activity. We investigated whether the US could predict subsequent adverse outcomes for patients with CD in clinical remission.
Methods:
This single-center retrospective study included patients with CD in clinical remission who underwent US between April 2011 and April 2021, focusing on the predictability of subsequent adverse outcomes within 5 years. We used the US-CD, which was calculated using multiple US findings. Predictive variables were assessed using Cox proportional hazards regression analysis, and the predictive value was evaluated using receiver operating characteristic curves.
Results:
Seventy-three patients were included. During a median follow-up of 1,441 days (range, 41–1,825 days), 16.4% (12/73) experienced clinical relapse, 9.6% (7/73) required endoscopic balloon dilation (EBD), 58.9% (43/73) required enhanced treatment, and 20.5% (15/73) underwent surgery. In the multivariate analysis, US-CD was significantly associated with clinical relapse (P= 0.038) and the need for enhanced treatment (P= 0.005). The area under the receiver operating characteristic curve for predicting clinical relapse and the need for EBD was 0.77 and 0.81, respectively, with US-CD (cutoff value = 11), and that for requiring enhanced treatment was 0.74 with US-CD (cutoff value = 6). Patients with US-CD ≥ 11 demonstrated a significantly higher occurrence of clinical relapse (P= 0.001) and EBD (P= 0.002) within 5 years. Patients with US-CD ≥ 6 experienced a significantly higher likelihood of requiring enhanced treatment (P< 0.001) within 5 years.
Conclusions
High US-CD is associated with subsequent adverse outcomes in patients with CD.
