5G‐based remote magnetically controlled capsule endoscopy for examination of the stomach and small bowel

Abstract

Background and aims Remote endoscopy can improve diagnostic efficiency of gastrointestinal (GI) diseases for patients in remote areas. A novel remote magnetically controlled capsule endoscopy (MCE) system based on a 5G network was developed for real‐time remote GI examinations. We aimed to evaluate the feasibility and safety of the 5G‐based remote MCE for examination of the stomach and small bowel. Methods This was a prospective, nonrandomized, comparative study. Consecutive participants enrolled in the First People's Hospital of Yinchuan underwent remote MCE examinations performed by an endoscopist located in Changhai Hospital. Consecutive participants enrolled in Changhai Hospital underwent conventional MCE examinations performed by the same endoscopist. The main outcomes included the complete visualization rate of the stomach and small bowel, safety assessment and network latency time of remote MCE examinations. Results From March 2021 to June 2021, 20 participants in each group were enrolled. The complete visualization rate of the stomach and small bowel was 100% in both groups (p > 0.999) without any adverse event. The median network latency time of remote MCE group was 19.948 ms. Gastric examination time (8.96 vs. 8.92 min, p = 0.234), maneuverability (15.00 vs. 15.00, p = 0.317), image quality (1.00 vs. 1.00, p > 0.999) and diagnostic yields in the stomach and small bowel (55% vs. 30%, 5% vs. 0%, both p > 0.05) were comparable between remote and conventional MCE groups. All participants in remote MCE group considered remote MCE acceptable and necessary. Conclusions 5G‐based remote MCE was a feasible and safe method for viewing the stomach and small bowel.

Capsule endoscopy and panendoscopy: A journey to the future of gastrointestinal endoscopy

“…It has the advantages of non-invasiveness, with an excellent safety profile and patient acceptance. Clinical indications for MCCE may include esophageal diseases such as esophageal varices and Barrett's esophagus[ 55 ], screening for gastric cancer[ 54 ], detection and surveillance for gastric or duodenal lesions such as ulcers, polyps, varices, erosive and atrophic gastritis, drug-related GI mucosal injury such as NSAIDs, remote gastric examination[ 56 ], stable patients with acute upper GI bleeding[ 57 ], or surveillance after partial gastrectomy or minimally invasive endoscopic treatment.…”

The Key Criteria for Predicting Unusual Behavior in the Elderly With Deep Learning Models Under 5G Technology

“…The study's findings suggest that using 5G technology in tandem with surgical robots could offer a promising new option for the treatment of kidney malignancies via telemedicine. Other studies associated to the implementation of 5G technology include the work that determined that remote gastrointestinal examinations using a 5G network in real time are a practical and secure way for observing stomach and small bowel [14]. Using a 5G network a teleoperated surgery demonstrated a seamless flow of tasks under the guidance of an expert surgeon [15].…”

“…It is crucial to note that the aforementioned works [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20] are still focusing on the implementation aspects of 5G in VOLUME 11, 2023 connection to its usage in the medical field. This is something that has to be brought to having a good attention.…”

On 5G, 6G, mmWave Usage in Colonoscopy

“…These procedures are uncomfortable and are in demand. Polyps may not necessarily lead to cancer, but current methods of colonoscopy miss around one (1) in five (5) of them due to old procedures.…”

“…The computer power embedded with 5G and beyond will help to accelerate benefits as we progress with the usage of the latest technology in health-care system. The reader is referred to [3,5,6].…”
