Background: Portal hypertensive enteropathy (PHE) is a small-bowel lesion observed in patients with portal hypertension. The clinical significance of endoscopic findings in PHE remains unclear. We aimed to clarify the clinical significance and predictive factors of capsule endoscopic findings in patients with PHE based on long-term outcomes.

Objectives: We aimed to evaluate the usefulness and acceptability of CapsoCam Plus (CapsoCam) in Japanese patients.

Methods: This retrospective single-center study enrolled 930 patients with suspected small-bowel bleeding (SSBB) who underwent capsule endoscopy. Thirty-three patients using CapsoCam and PillCam SB3 (SB3) were matched using propensity score matching.

Background And Aim: Although small-bowel capsule endoscopy (CE) is widely used for obscure gastrointestinal bleeding (OGIB), long-term outcomes for OGIB patients after negative CE remain unclear. Herein, we defined negative CE as P0 (no bleeding potential) or P1 (less likely to bleed), based on the P classification using CE. We aimed to clarify long-term outcomes of patients with OGIB after negative CE.

Background And Aims: Capsule endoscopy (CE) is useful in evaluating disease surveillance for primary small-bowel follicular lymphoma (FL), but some cases are difficult to evaluate objectively. This study evaluated the usefulness of a deep convolutional neural network (CNN) system using CE images for disease surveillance of primary small-bowel FL.

Methods: We enrolled 26 consecutive patients with primary small-bowel FL diagnosed between January 2011 and January 2021 who underwent CE before and after a watch-and-wait strategy or chemotherapy.

Objectives: Capsule endoscopy (CE) has been shown to have poor diagnostic performance when the capsule passes quickly through the small bowel, especially the proximal jejunum. This study aimed to evaluate the diagnostic yield of proximal jejunal lesions with third-generation CE technology.

Methods: We retrospectively examined 138 consecutive patients, 76 (55.

Background: Primary small-bowel follicular lymphoma (FL) is mainly diagnosed as a duodenal lesion during esophagogastroduodenoscopy. Recently, with the widespread use of small-bowel endoscopy, FL in the jejunum and ileum has been detected. Most patients with small-bowel FL are diagnosed at the localized stage, and a watch-and-wait policy is used.

Objectives: A single-balloon overtube (SBO) can improve poor scope operability during colonic endoscopic submucosal dissection (ESD). We aimed to evaluate the clinical usefulness of SBO for ESD in the proximal colon and the predictive factors for cases in which SBO is useful.

Methods: A total of 88 tumors located in the proximal colon resected by balloon-assisted ESD (BA-ESD) using SBO and 461 tumors resected by conventional ESD (C-ESD) between June 2015 and November 2020 were considered.

With the increasing use of capsule endoscopy (CE), screening tests for the small bowel can be performed with minimal invasiveness. However, occasionally, the entire small bowel cannot be observed because of decreased peristalsis of the stomach. For such cases, we perform delivery of CE by an endoscope.

Systemic sclerosis (SSc) is characterized by fibrosis of the skin and various internal organs. However, there is limited knowledge concerning small-bowel lesions. We evaluated the clinical state of patients with SSc according to the capsule endoscopy (CE) findings.

Article Synopsis
  • Systemic sclerosis (SSc) is an autoimmune disease characterized by organ fibrosis and vascular damage, often leading to small-bowel angioectasias in patients.
  • A study evaluated the outcomes of polidocanol injection (PDI) for treating gastrointestinal bleeding in SSc patients with small-bowel angioectasia, finding that these patients often had lower hemoglobin levels and more skin telangiectasia.
  • The results showed that PDI was both safe and effective, with no instances of rebleeding or adverse events, suggesting that endoscopy should be performed in SSc patients who present with anemia or skin symptoms.

Article Synopsis
  • A retrospective study was conducted on 10,156 patients to assess the safety and effectiveness of endoscopic delivery of capsule endoscopes, including small bowel, patency, and colon capsules.
  • The endoscopic delivery method was successful in a majority of cases, with mild complications reported in about 21.6% of patients, mostly minor issues like mucosal damage and abdominal pain.
  • Results showed that younger patients (<16 years) had a higher success rate of capsule ingestion, while older patients (≥16 years) faced more challenges, predominantly due to conditions like dysphagia and other health issues.

The current understanding of clinicopathological features and genomic variants of small-bowel cancer is limited, in part due to the rarity of the disease. However, understanding of these factors is necessary for the development of novel therapeutic agents for small-bowel cancer. Thus, we aimed to identify the clinicopathological features and genomic variants associated with its prognosis and recurrence.

Introduction: Muscle cramps are common comorbidities in chronic liver disease (CLD). Although the prevalence of these has been reported in patients with liver cirrhosis (LC), that of CLD is unknown. In this study, we aimed to clarify the prevalence and characteristics of muscle cramps in individual CLD.
