Background: Abdominal pain after bariatric surgery (BS) is frequently observed. Despite numerous diagnostic tests, the cause of abdominal pain is not always found.
Objectives: To quantify type and number of diagnostic tests performed in patients with abdominal pain after BS and evaluate the burden and their yield in the diagnostic process.
Purpose: Long-term follow-up after bariatric surgery (BS) reveals high numbers of patients with abdominal pain that often remains unexplained. The aim of this prospective study was to give an overview of diagnoses for abdominal pain, percentage of unexplained complaints, number and yield of follow-up visits, and time to establish a diagnosis.
Materials And Methods: Patients who visited the Spaarne Gasthuis Hospital, The Netherlands, between December 2020 and December 2021 for abdominal pain after BS, were eligible and followed throughout the entire episode of abdominal pain.
Background And Aims: Controversy remains regarding the type and amount of precapsule bowel cleansing required for small-bowel video capsule endoscopy (VCE). This study aims to assess the efficacy and tolerance of 2 active preparations and a control group of clear fluids only.
Methods: Patients with clinical indications for VCE were randomized to (1) clear fluids only the evening before VCE, (2) 2 sachets of sodium picosulfate plus magnesium sulfate (P/MC) the evening before, or (3) 2 L of polyethylene glycol (PEG) the evening before.
Background: Modern small bowel imaging techniques allow detailed depiction of small-intestinal abnormalities. The role of these techniques in the investigation of celiac disease is increasing, especially in patients with suspected complicated celiac disease.
Key Messages: In general, there is no need for radiological small bowel imaging in uncomplicated celiac disease.
A double-duct sign is the combined dilatation of the common bile duct and pancreatic duct, often caused by cancer of the pancreas. We present a patient with colicky pain in the right upper quadrant of her abdomen. On radiological imaging and endosonography, she had a double-duct sign due to choledocholithiasis and no mass in the pancreatic head.

We aimed to describe video capsule endoscopy (VCE) findings in patients with CD and persisting or relapsing symptoms despite a gluten-free diet and to identify VCE findings associated with poor prognosis.
Methods: We retrospectively analyzed 48 VCE studies performed in adult patients with CD because of persisting or relapsing symptoms despite adherence to a gluten-free diet.
Background And Aim: Little is known about the causes of overt obscure gastrointestinal bleeding (OGIB) in patients using anti-thrombotic therapy. We aimed to describe video capsule endoscopy (VCE) findings and to identify factors associated with positive findings in these patients.
Methods: We carried out a retrospective study of 56 patients who underwent VCE for evaluation of previous overt OGIB during anti-thrombotic therapy.
Purpose: To evaluate the diagnostic accuracy of MR enteroclysis and to compare it to video capsule endoscopy (VCE) in the analysis of suspected small-bowel disease.
Methods: We performed a retrospective analysis of 77 patients who underwent both MR enteroclysis and VCE and compared the findings of these studies with the findings of enteroscopy, surgery, or with the results of clinical follow-up lasting ≥2 years.
Results: Findings included malignant neoplasms (n = 13), benign neoplasms (n = 10), refractory celiac disease (n = 4), Crohn's disease (n = 2) and miscellaneous conditions (n = 10).
Purpose: To determine magnetic resonance (MR) enteroclysis findings in patients with uncomplicated celiac disease (CD), refractory CD (RCD) type I, and RCD type II, to develop and validate a scoring system to identify patients with RCD II and to determine the diagnostic accuracy of MR enteroclysis to detect CD-related malignancies.
Materials And Methods: This study was performed with approval of the institutional review board. One radiologist blinded to clinical details retrospectively evaluated quantitative and qualitative criteria of 28 studies obtained in symptomatic patients with CD (uncomplicated CD, n = 10; RCD I, n = 8; RCD II, n = 10).
Recently the incidence of oesophageal carcinoma has increased predominantly due to a rise in the incidence of adenocarcinoma. A relationship with the increasing prevalence of Barrett's oesophagus plays an important role. Diagnosis and staging should include oesophago-gastro-duodenoscopy, transoesophageal endo-echography and computer tomography.

We report a case of gallstone ileus in an 88-year old female patient. The correlation between computed tomography, double-balloon enteroscopy and intra-operative findings is discussed, as well as treatment strategies.

This study aims at determining the diagnostic yield of capsule endoscopy for obscure gastrointestinal bleeding using a structured terminology in a large cohort in an academic hospital.
Methods: In this retrospective study, 592 capsule endoscopy procedures performed in a tertiary hospital were analysed using the Capsule Endoscopy Structural Terminology.
