Abstract

Objective: To explore the detective value of magnetically controlled robotic capsule endoscopy (MCRCE) in patients with suspected small intestinal disease.Patients and Methods: In total, 1,802 patients with suspected small intestinal disease and negative gastroenteroscopy from Shanghai Jiao Tong University Affiliated Sixth People's Hospital were examined with MCRCE, and the data were collected for further analysis.Results: Among the 1,802 patients who were examined with MCRCE, 974 were diagnosed with small intestinal disease, reaching a positive detection rate of 54.1%. The five most common conditions that were detected include non-specific enteritis in 722 cases (40.1%), small intestinal ulcers in 87 cases (4.8%), abnormal small bowel evacuation in 45 cases (2.5%), small intestinal bleeding in 33 cases (1.8%), and small intestinal yellow spots in 31 cases (1.7%). The running time of the capsules in the small intestine ranged from 85–437 min, with an average of 210.24 ± 89.08 min. No complications, such as intestinal obstruction or capsule retention, were observed in all patients.Conclusion: MCRCE is a safe and non-invasive endoscopic examination with a highly accurate detection rate for small intestinal diseases.

Highlights

With a total length of 5–7 m in adults, the small intestine is the longest part of the alimentary canal
This study suggests that magnetically controlled robotic capsule endoscopy (MCRCE) is a potential primary choice for the examination of small bowel diseases
Small intestinal bleeding emerges from between the suspensory ligament of the duodenum and the Bauhin’s valve, accounting for 5% of all gastrointestinal bleeding (GIB) and 80% of obscure GIB cases [18]

Summary

Introduction

With a total length of 5–7 m in adults, the small intestine is the longest part of the alimentary canal. Diseases of the small intestine are important components of digestive tract diseases. These diseases are clinically present as gastrointestinal bleeding, abdominal pain, diarrhea, and constipation. The incidence of small bowel disease in China is unclear due to insufficient national epidemiological investigations. The unique structure of the intestine, including its deep position, dissociation from the peritoneum, and multiple composite mesenteries, contributes to the difficulty in diagnosing small intestinal diseases. It is urgent to develop a new and effective detective tool for the diagnosis of small intestinal diseases
