Objective: This study evaluated the risks and outcomes of capsule retention during capsule endoscopy (CE) for investigating small bowel disease. Capsule retention is the most serious complication of CE.
Methods: Before CE, the gastrointestinal tract was evaluated for blockages with computerized tomography. Analysis of CE was made retrospectively.
Results: Capsule endoscopy was used to investigate obscure bleeding (90.2%; n = 324) or other symptoms (9.8%; n = 35). The capsule retention rate was 11/359 (3.1%); it was retained in a malignant lesion area (adenocarcinoma or melanoma) in two patients (18.2%), in the small bowel in an ulcerated area in five patients (45.5%), and in the oesophagus/stomach in four patients (36.4%) due to dysmotility. None of the patients had symptoms of obstruction.
Conclusions: Scanning patients before CE did not predict capsule retention. Retention is a complication of CE, but occurs as a result of the underlying disease. The risk of retention is increased in patients with motility disorders, suspected small bowel ulcers or malignancies.

Extended 72-hour patency capsule protocol improves functional patency rates in high-risk patients undergoing capsule endoscopy.

Background: Capsule endoscopy (CE) is a pivotal diagnostic tool for gastrointestinal (GI) disorders, yet capsule retention poses a significant risk, especially in patients with known risk factors. The patency capsule (PC) helps assess the functional patency of the GI tract to mitigate this risk. However, the standard 28-hour protocol for confirming patency often results in high false-positive rates, unnecessarily excluding many patients from undergoing diagnostic CE.

Background: Video capsule retention is a complication that can have serious consequences in patients with Crohn's disease (CD). The patency capsule was developed to detect small bowel strictures. The usefulness of patency capsules in patients who do not have evidence of small bowel disease on imaging is uncertain.

Background The utility of small bowel capsule endoscopy (SBCE) in the inpatient setting is controversial due to retention rates and costs. Aim This study aims to evaluate whether using SBCE significantly improved the identification of potential bleeding sites or reduced the risk of 30-day readmission for overt or occult gastrointestinal bleeding. Methods This was a single-center retrospective cohort study involving inpatients who underwent SBCE at a suburban tertiary care hospital from January 1, 2012, to January 1, 2022, for suspected small bowel bleeding.

Research on shape memory materials (SMM) or smart materials, along with advancements in printing technology, has transformed three-dimensional (3D) printing into what we now refer to as 4D printing. In this context, the addition of time as a fourth dimension enhances 3D printing. 4D printing involves the creation of 3D-printed objects that can change their shapes into complex geometries when influenced by external stimuli such as temperature, light, or pH over time.

Ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS), UNIFI software, and a self-built compound library of Longxuejie Capsules were employed to analyze the pharmacodynamic substances of Longxuejie Capsules and the metabolites in rats. The methanol extracts of capsule contents as well as the plasma, urine, and fecal metabolites of rats after drug administration were prepared. Data were collected in both positive and negative MS~E Continuum scan modes via UPLC-Q-TOF-MS.
