Association between patient characteristics and magnetically controlled capsule endoscopy findings

Abstract

Background/Aim:Magnetically-controlled capsule endoscopy (MCE) is a potential option for the evaluation of gastric diseases in cases that are unsuited for conventional endoscopy, avoiding discomfort, sedation, and related complications. This retrospective study investigated associations between MCE findings and patient gender, age, and inpatient/outpatient status.Patients and Methods:The data of 580 consecutive patients who underwent MCE from 2015 to 2016 were analyzed. Data included age, gender, indication for MCE, inpatient/outpatient status, overall coverage of gastric anatomical landmarks, and comorbid conditions.Results:Compared with outpatients, inpatients had a higher rate of overall significant MCE findings (P = 0.014), polyp (P = 0.03), and ulceration (P = 0.003). MCE findings of the inpatient men and women were similar. Considering all patients, the percentage with ulceration was significantly higher in men than in women (P = 0.004), and men were younger (P < 0.001). Compared with younger patients, those aged ≥60 years had significantly higher rates of overall significant findings, mainly polyp and angiodysplasia.Conclusions:Compared with outpatients, the inpatients showed higher overall significant findings. Men undergoing MCE were younger than the women, and more likely to have ulcerations. Older patients, whether outpatient or inpatient, had higher rates of significant findings, mainly polyp and angiodysplasia.

“…The rate of complete small bowel examination using MCCG varies from 75.1% to 100%. 31,57,58 A prospective cohort study included 49 patients with recurrent or refractory iron deficiency anemia who underwent MCCG and EGD, showing that MCCG had a higher lesion detection rate and higher diagnostic yield in the upper GI tract than conventional EGD, with a better tolerance. 31 In a retrospective study involving 226 patients with suspected small bowel disease (with negative gastroscopy results and GI symptoms), the completion rate of MCCG (NaviCam) for small bowel examination was 97.79%, and the detection rate of small bowel disease was 77.43%, including enterocolitis, ulcers, vascular diseases, polyps, tumors, and diverticula.…”

“…The magnetic ball is held at the patient's right shoulder to observe the fundus, the junction of Thus, a shorter GTT may improve the completion rate of a small bowel examination. 38,57 Two studies on robotic-arm MCCG (NaviCam) found that magnetic steering significantly accelerated the passage of the capsule through the pylorus (with a success rate of 59% within 30 min and a reduction of the GTT from 84 to 22 min), and real-time observation of the duodenum under magnetic control improved the detection rate of the duodenal papilla (from 9% to 30%)…”

“…SBCE is the first‐line examination for detecting small bowel diseases, 56 and some types of MCCG can be used for small bowel examination after its passage through the stomach owing to its long battery life. The rate of complete small bowel examination using MCCG varies from 75.1% to 100% 31,57,58 . A prospective cohort study included 49 patients with recurrent or refractory iron deficiency anemia who underwent MCCG and EGD, showing that MCCG had a higher lesion detection rate and higher diagnostic yield in the upper GI tract than conventional EGD, with a better tolerance 31 .…”

“…A single‐center retrospective study showed that 129 children (6–14 years of age) successfully completed the MCCG (NaviCam) examination without significant adverse events 60 . Several studies have confirmed the safe application of MCCG in the elderly (>60 years of age), 40,54,57,61 in which the eldest participant reported was up to 94 years of age 40 . It is worth noting that adverse events, such as capsule retention and aspiration, are more likely to occur in the elderly 61,62 .…”

“…Some types of MCCG can be used to further examine the duodenum and small bowel with an average gastric transit time (GTT) of 1–2 h, which affects the comprehensive examination of the small bowel. Thus, a shorter GTT may improve the completion rate of a small bowel examination 38,57 . Two studies on robotic‐arm MCCG (NaviCam) found that magnetic steering significantly accelerated the passage of the capsule through the pylorus (with a success rate of 59% within 30 min and a reduction of the GTT from 84 to 22 min), and real‐time observation of the duodenum under magnetic control improved the detection rate of the duodenal papilla (from 9% to 30%) and the completion rate of small bowel examination (from 94% to 100%) 58,72 .…”
