Búsqueda de optimización de la cápsula endoscópica mediante análisis observacional

ObjectivesTo search for parameters susceptible to optimization when performing capsule endoscopy (CE) in a third level hospital with high volume and experience in this test. Patients and methodsRetrospective observational study, including 1325 CEs performed between 2017 and 2022. Overall diagnostic yield, effective diagnostic yield, by indication, place of request and waiting list, as well as complete examination rate and cleansing degree were analyzed. ResultsThe overall diagnostic yield was 70.99%, while the effective diagnostic yield was 72.7%. Diagnostic yields varied between 60.2% and 77.9% depending on the indication and between 64.7% and 74.3% depending on the requesting center. The mean waiting list was 101.15 days, with a tendency to worse results when the waiting list was longer. A total of 77.8% of the examinations were complete. Completion rates were lower in patients >70 years of age (p=0.001), as well as in those with gastric transit >60minutes (p=0.000). A total of 77.3% were clean, with debris that did not impede diagnosis being found in 16.9% and debris that did impede diagnosis in 5.8%. There was a relationship, although not significant, between cleansing degree and age. ConclusionsThe diagnostic yields of CE in our center are in line with those previously reported. Differences were found according to the place of request. Waiting list could also influence diagnostic yield. Completion rates are lower in >70 years of age and when gastric transit is >60minutes. Cleansing degree achieved is acceptable.

Feasibility and Safety of 5G-Based Telerobotic Abdominal Ultrasonography.

Telemedicine can offer services to remote patients regardless of the distance. Fifth-generation (5G) mobile networks may make telemedicine practical because of their low latency. This study aimed to evaluate the feasibility and safety of a novel 5G robot-assisted remote abdominal ultrasound (AUS) telemedicine technology in clinical applications in distant locations. We performed 5G-based telerobotic AUS in patients who were located more than 100 km away from the physicians. The telerobotic AUS had a longer examination time than the conditional bedside AUS; however, the complete examination rate was not inferior. None of the volunteers experienced discomfort during the examination and the examination time was acceptable for all. Our findings confirm the feasibility and safety of 5G-based telerobotic AUS in clinical practice.

A novel capsule endoscopy for upper and mid-GI tract: the UMGI capsule

Backgrounds and AimsComplete and consecutive observation of the gastrointestinal (GI) tract continues to present challenges for current endoscopy systems. We developed a novel upper and mid gastrointestinal (UMGI) capsule endoscopy using the modified detachable string magnetically controlled capsule endoscopy (DS-MCE) and inspection method and aimed to assess the clinical application.MethodsPatients were recruited to undergo UMGI capsule endoscopy followed by esophagogastroduodenoscopy. All capsule procedures in the upper gastrointestinal (UGI) tract were conducted under the control of magnet and string. The main outcome was technical success, and the secondary outcomes included visualization of the UMGI tract, examination time, diagnostic yield, compliance, and safety evaluation.ResultsThirty patients were enrolled and all UMGI capsule procedures realized repeated observation of the esophagus and duodenum with detection rates of 100.0%, 80.0%, and 86.7% of Z-line, duodenal papilla, and reverse side of pylorus, respectively. String detachment was succeeded in 29 patients (96.7%) and the complete examination rate of UMGI tract was 95.45% (21/22). All UMGI capsule procedures were well tolerated with low discomfort score, and had a good diagnostic yield with per-lesion sensitivity of 96.2% in UGI diseases. No adverse events occurred.ConclusionsThis new capsule endoscopy system provides an alternative screening modality for the UMGI tract, and might be indicated in cases of suspected upper and small bowel GI bleeding.Trial registration DS-MCE-UGI and SB, NCT04329468.

Upper endoscopy photodocumentation quality evaluation with novel deep learning system.

Visualization and photodocumentation during endoscopy procedures are suggested to be one indicator for endoscopy performance quality. However, this indicator is difficult to measure and audit manually in clinical practice. Artificial intelligence (AI) is an emerging technology that may solve this problem. A deep learning model with an accuracy of 96.64% was developed from 15,305 images for upper endoscopy anatomy classification in the unit. Endoscopy images for asymptomatic patients receiving screening endoscopy were evaluated with this model to assess the completeness of photodocumentation rate. A total of 15,723 images from 472 upper endoscopies performed by 12 endoscopists were enrolled. The complete photodocumentation rate from the pharynx to the duodenum was 53.8% and from the esophagus to the duodenum was 78.0% in this study. Endoscopists with a higher adenoma detection rate had a higher complete examination rate from the pharynx to duodenum (60.0% vs. 38.7%, P < 0.0001) and from esophagus to duodenum (83.0% vs. 65.7%, P < 0.0001) compared with endoscopists with lower adenoma detection rate. The pharynx, gastric angle, gastric retroflex view, gastric antrum, and the first portion of duodenum are likely to be missed by endoscopists with lower adenoma detection rates. We report the use of a deep learning model to audit endoscopy photodocumentation quality in our unit. Endoscopists with better performance in colonoscopy had a better performance for this quality indicator. The use of such an AI system may help the endoscopy unit audit endoscopy performance.

Can domperidone decrease transit time of pediatric video capsule endoscopy? A randomized controlled trial.

BackgroundThe complete examination rate of video capsule endoscopy can be increased by reduced gastric transit time (GTT) and or small bowel transit time (SBTT). This study aims to examine whether the prokinetic domperidone reduces GTT and/or SBTT in pediatric patients undergoing video capsule endoscopy (VCE).MethodsWe performed a single-center randomized controlled trial (n=200) to evaluate the effect of domperidone on GTT and SBTT among pediatric patients in a tertiary university-affiliated hospital for children. We explored whether patients randomized to domperidone had increased GTT, SBTT (primary outcomes) or higher complete examination rate (secondary outcome). The safety outcomes were the adverse effects in the domperidone group. This study was registered on ClinicalTrials.gov (NCT03662113).ResultsDemographic features including gender and age were similar between the 100 patients of the domperidone group and the 100 patients of the control group. The median GTT was 67.5 minutes (44.8–117.5) in the domperidone group and 80.0 minutes (42.0–128.0) in the control group, while the median SBTT was 317 minutes (231–436) and 323 minutes (225–426), respectively. There were no significant differences in GTT (P=0.49) and SBTT (P=0.52) between the two groups. The complete examination rate was 97% and 98% in the domperidone and control groups, respectively (P=1.00).ConclusionsDomperidone shows no effect on GTT, SBTT and complete examination rate in pediatric patients receiving VCE.

Su1325 PROLONGED OPERATING TIME HAVE A SUBSTANTIAL EFFECT ON PROMOTING COMPLETE EXAMINATION RATE OF CAPSULE ENDOSCOPY COMPARED WITH ENDOSCOPIC DELIVERY OF CE ALONE

Small bowel capsule endoscopy (SB CE) has become the gold standard for the investigation of small bowel diseases. The most common applications of CE include obscure gastrointestinal bleeding (OGIB), suspected Crohn’s disease, small-intestine tumors and polyps, etc. The diagnostic yield of SB CE has been reported to vary widely and can be affected by many factors, such as indications, bowel preparation, reviewers’ experience, and so on. Complete examination was defined as capsule passing through the whole small intestine during its working time, and the complete examination rate (CER) is also one of the important factors that can influences the diagnostic yield of CE. Some methods have been adopted to promote the CER; among them are real-time monitoring plus endoscopic delivery of CE into the duodenum and prolonging examination time with increased battery life. In order to study which of the two methods mentioned above is more effective for improving the CER, three types of modality of CE examination were analyzed. We conducted a retrospective review of 241 consecutive patients, 61 of whom had undergone 8-h PillCam SB CE (8 h operating time) from July 2005 to April 2011 without real-time monitoring, 7 consecutive 8-h PillCam SB CE and 173 consecutive 12 h PillCam SB2-ex (12 h operating time) patient all with real-time monitoring and endoscopic delivery of CE if necessary (CE unable pass through the pylorus 1.5 h after the start of the inspection) from July 2011 to November 2018. We grouped the patients as follows: A, 61 cases 8-h PillCam CE without real-time monitoring; B, 180 cases 8-h PillCam CE with monitoring (7 actual 8 h, and 173 actual 12 h but assumed the CE only work for 8 h and only data of the former 8 h were calculated); C, 173 cases 12 h PillCam SB2-ex actual data. GTT (gastric transit time), SBTT (Small bowel transit time) and CER of the three groups were analyzed. We found that twenty-nine (16.1%, 29/180) endoscopic delivery of CE were performed in group B, but there was no difference between group A and B in GTT, SBTT or CER. CER of group C (94.8%, 164/173) was much higher than that of group A (78.7%, 48/61) or B (72.8%, 131/180) (Chi-square test with Bonferroni correction; C vs. A, p ＜ 0.01 & C vs. B, p ＜ 0.001), and SBTT of group C (322.0 ± 133.1 min) was much longer than that of group A (253.8 ± 80.9 min) or B (269.3 ± 98.4 min) (One-Way ANOVA Tamhane's T2 or Dunnett's T3 test; C vs. A & C vs. B, p ＜ 0.001) (table 1). In conclusion, longer operating time have a substantial effect on promoting complete examination rate of CE, while endoscopic delivery of CE have little or no effect on it. Endoscopic delivery of CE plays a role in eliminating the risk of inspection failure, such as unable to ingestion, or excessive time wasted in the esophagus or stomach, but too early or too frequently endoscopic delivery of CE is not necessary.

Booster medication to achieve capsule excretion in colon capsule endoscopy: a randomized controlled trial of three regimens.

Background and study aims To achieve a complete colon capsule endoscopy, the entire colon must be visualized, clean and filled with clear fluids. The primary aim was to compare three booster regimens in colon capsule endoscopy in achieving capsule excretion within recording time. Secondary aims were quality of bowel cleansing and completion rate (both adequate cleansing and capsule excretion). Patients and methods Patients scheduled for follow-up colonoscopy due to previous neoplastic findings or familial history of colorectal cancer aged 18 to 70 years were eligible. Bowel preparation was 2-L split doses of polyethylene glycol. Patients were randomized to three booster regimens of either polyethylene glycol (Group A), sulfate-based solution (Group B) or polyethylene glycol with iodine oral contrast (Group C). Results One hundred eighty participants were included and randomized into three groups of 60. Capsule excretion was 70 % (95 % CI: 58 – 80) in Group A, 73 % (95 % CI: 61 – 83) in Group B and in 68 % (95 % CI: 56 – 79) in Group C, no statistically significant differences. Bowel cleansing grade was statistically significant better in Group B compared to Group A ( P = 0.03), but there were no statistically significant differences between Groups C and A ( P = 0.40). Complete examination rate was 65 % (95 % CI: 53 – 77), 72 % (95 % CI: 61 – 83) and 62 % (95 % CI: 50 – 74) in Group A, B and C respectively, not statistically significant different. Conclusions Sulfate-based solution resulted in statistically significant better bowel cleansing compared to polyethylene glycol. Overall the excretion and completion rate was suboptimal. Achieving a high completion rate using patient-tolerable and low-risk compounds is still a challenge.

Sham Feeding with Bacon Does Not Alter Transit Time or Complete Examination Rate During Small Bowel Capsule Endoscopy.

During capsule endoscopy (CE) studies, the complete examination rate (CER) can be increased by prolonging capsule battery life or reducing gastric transit time (GTT) and/or small bowel transit time (SBTT). However, despite enhanced battery life, 10% of studies remain incomplete. Previously studied interventions to reduce SBTT and enhance CER have produced conflicting results. We hypothesize that this may be a consequence of an insufficiently potent stimulus of small bowel motility. To examine whether potent stimulation of the cephalic response of digestion during small bowel CE reduces GTT and/or SBTT and thus increases the CER. A single-blind randomized trial was performed to evaluate the effect of bacon sham feeding on GTT, SBTT and CER. Baseline characteristics were similar between 63 sham fed patients and 59 controls. The median GTT was 17min (9-65) in the bacon group and 25min (14-55) in the control group. The median SBTT was 199min (119-316) and 222min (151-287), respectively. Cox proportional hazards model demonstrated no significant difference between groups for GTT (rate ratio 1.03, 95% CI 0.71-1.51, P=0.87) or SBTT (rate ratio 1.02, 95% CI 0.70-1.49, P=0.93). Although the taste of bacon was considered favorably by 72% of participants, taste did not correlate with GTT (ρ=0.03, P=0.83) or SBTT (ρ=-0.115, P=0.33). The CER was 91 and 95% in the bacon and control groups, respectively (P=0.35). Bacon sham feeding has no effect on GTT, SBTT or CER and cannot be recommended in clinical practice.

How is shoulder ultrasound done in Italy? A survey of clinical practice.

To define when an ultrasound examination of the shoulder can be considered complete and how many examinations currently performed in Italy are actually complete according to that definition. Reports and images of previously performed ultrasound examinations of the shoulder of patients seen in 2014 for interventional procedures were reviewed for the following items, according to guidelines published by the European Society of Musculoskeletal Radiology: long biceps, subscapularis, supraspinatus, external rotators, acromioclavicular joint, subacromial bursa, subacromial space, coraco-acromial ligament, and the posterior recess. The first six items were considered mandatory in a complete shoulder ultrasound examination. The specialization of the performing physician was noted. The number of complete examinations performed by different physicians was compared with the number of incomplete examinations. We analyzed 324 examinations (212 women, 112 men; mean age = 47 ± 12years). The most frequently reported item was the supraspinatus tendon (83%), the least frequently reported was the posterior recess (3%). The image that was most frequently found was the long head of the biceps tendon (77%), the least frequently found was the coraco-acromial ligament (3%). The median number of images/examination was 6 (25th-75th percentiles, range 4-9). The mean number of unrecognizable images was 3 (2-4). A radiologist performed the examination in 269 patients (83%). The rate of complete examinations was 47%. The number of complete examinations performed by physicians from different specialties was not significantly different from that of incomplete examinations (P = 0.228). Complete shoulder ultrasound examinations account for less than 50% of those performed in clinical practice in some Italian regions. Standardized scanning protocols and structured reporting may help to improve this figure and consistency among providers performing these examinations.

Obstetric ultrasound quality improvement initiative-utilization of a quality assurance process and standardized checklists.

Our aim was to assess whether mandated completion of an electronic checklist and a quality assurance (QA) process improved obstetric (OB) ultrasound image documentation. A checklist of mandated images based on the American Institute of Ultrasound in Medicine guidelines was created. A baseline QA assessment was performed with a lead senior sonographer reviewing eight random OB examinations for each sonographer. An electronic checklist was then instituted for all OB examinations on each ultrasound machine. It was mandated that each anatomical structure be checked off during real-time image acquisition. A repeat QA assessment of each sonographer was then performed quarterly. Baseline assessments were performed between September 2011 and November 2011. Out of the 110 examinations analyzed, only 49% were deemed "complete" with none of the sonographers having a 100% complete examination rate. Following institution of the mandated electronic checklist, a repeat assessment revealed an 81% complete examination rate for the next quarter, and 90% were complete at the end of a year. All sonographers improved their image acquisition regardless of baseline skill level at the initial QA. A QA process and a mandated standardized electronic checklist improved the image documentation.

Oral purgative and simethicone before small bowel capsule endoscopy

To evaluate small bowel cleansing quality, diagnostic yield and transit time, comparing three cleansing protocols prior to capsule endoscopy. Sixty patients were prospectively enrolled and randomized to one of the following cleansing protocols: patients in Group A underwent a 24 h liquid diet and overnight fasting; patients in Group B followed protocol A and subsequently were administered 2 L of polyethylene glycol (PEG) the evening before the procedure; patients in Group C followed protocol B and were additionally administered 100 mg of simethicone 30 min prior to capsule ingestion. Small bowel cleansing was independently assessed by two experienced endoscopists and classified as poor, fair, good or excellent according to the proportion of small bowel mucosa under perfect conditions for visualization. When there was no agreement between the two endoscopists, the images were reviewed and discussed until a consensus was reached. The preparation was considered acceptable if > 50% or adequate if > 75% of the mucosa was in perfect cleansing condition. The amount of bubbles was assessed independently and it was considered significant if it prevented a correct interpretation of the images. Positive endoscopic findings, gastric emptying time (GET) and small bowel transit time (SBTT) were recorded for each examination. There was a trend favoring Group B in achieving an acceptable (including fair, good or excellent) level of cleansing (Group A: 65%; Group B: 83.3%; Group C: 68.4%) [P = not significant (NS)] and favoring Group C in attaining an excellent level of cleansing (Group A: 10%; Group B: 16.7%; Group C: 21.1%) (P = NS). The number of patients with an adequate cleansing of the small bowel, corresponding to an excellent or good classification, was 5 (25%) in Group A, 5 (27.8%) in Group B and 4 (21.1%) in Group C (P = 0.892). Conversely, 7 patients (35%) in Group A, 3 patients (16.7%) in Group B and 6 patients (31.6%) in Group C were considered to have poor small bowel cleansing (P = 0.417), with significant fluid or debris such that the examination was unreliable. The proportion of patients with a significant amount of bubbles was 50% in Group A, 27.8% in Group B and 15.8% in Group C (P = 0.065). This was significantly lower in Group C when compared to Group A (P = 0.026). The mean GET was 27.8 min for Group A, 27.2 min for Group B and 40.7 min for Group C (P = 0.381). The mean SBTT was 256.4 min for Group A, 256.1 min for Group B and 258.1 min for Group C (P = 0.998). Regarding to the rate of complete examinations, the capsule reached the cecum in 20 patients (100%) in Group A, 16 patients (88.9%) in Group B and 17 patients (89.5%) in Group C (P = 0.312). A definite diagnosis based on relevant small bowel endoscopic lesions was established in 60% of the patients in Group A (12 patients), 44.4% in Group B (8 patients) and 57.8% in Group C (11 patients) (P = 0.587). Preparation with 2 L of PEG before small bowel capsule endoscopy (SBCE) may improve small bowel cleansing and the quality of visualization. Simethicone may further reduce intraluminal bubbles. No significant differences were found regarding GET, SBTT and the proportion of complete exploration or diagnostic yield among the three different cleansing protocols.

Intramuscular Injection of Metoclopramide Decreases the Gastric Transit Time and Does Not Increase the Complete Examination Rate of Capsule Endoscopy: A Prospective Randomized Controlled Trial

Capsule endoscopy (CE) reaches the cecum in about 80% of cases. Decreasing the gastric transit time (GTT) may increase the complete examination rate (CER). Patients (n=177) were prospectively randomized into 2 groups: the control group (n=88) and the intramuscular injection with metoclopramide (IIM) group (n=89). The OMOM CE system, which has the function of real-time monitoring, was used. The patients were injected with metoclopramide 15 minutes before swallowing the CE in the IIM group. The CE would be sent into the duodenum by gastroscopy if the GTT reached 120 minutes in the two groups. No significant difference was noted between the two groups. Of the 169 cases without gastroscopic help, the mean GTT was shorter in the IIM group (n=87) than the control group (n=82) (p=0.002). But the CER was similar. Of 135 cases without gastroscopic help but reached the cecum, the mean GTT was shorter in the IIM group (n=71) than the control group (n=64) (p=0.015). But the mean small bowel transit time (SBTT) was similar. Intramuscular injection of metoclopramide decreases the gastric transit time, but it does not change the SBTT or CER of capsule endoscopy in our study.

511k: Erythomycin Administration in Hospitalized Patients Undergoing Capsule Endoscopy: A Prospective and Randomized Controlled Trial

Small bowel capsule endoscopy (SBCE) accuracy depends on the rate of complete examinations. As previously demonstrated, in up to 30% of procedures the capsule does not reach the cecum. One of the main factors related to incomplete examinations is the patient's hospitalization. The aim of this study was to evaluate the effect of erythromycin administration in hospitalized patients undergoing CE.

Reduction of capture rate in the stomach increases the complete examination rate of capsule endoscopy: a prospective randomized controlled trial

A capsule endoscope failed to reach the cecum in approximately 20% of cases, with delayed gastric emptying being the most common cause. We hypothesized that reduction of the capture rate in the stomach saves the battery life and thus allows the capsule endoscope to reach the cecum. The aim of this study was to determine whether reduction of the capture rate of a capsule endoscope in the stomach increases the complete examination rate (CER). An endoscopy center in a teaching hospital in Shanghai. A prospective randomized controlled trial. A total of 50 patients were prospectively randomized into 2 groups: modified capture rate (MCR) group (n = 25) and the control group (n = 25). The OMOM capsule endoscopy system, which has the functions of viewing images in real time and modifying the capture rate during the examination, was used. In patients in the MCR group, the capture rate of the capsule endoscope was initially set at 0.5 frames per second (fps) and then was modified to 2 fps once the capsule endoscope passed the pylorus; whereas, in patients in the control group, the capture rate of the capsule endoscope was set and kept at 2 fps during the entire recording. The primary outcome was CER, and the secondary outcome was the total work time of the capsule. There was no significant difference in sex distribution, mean age, the number of hospitalized patients, and indications between the 2 groups. The CER was significantly higher in the MCR group than in the control group (100% vs 72%, respectively; P = .014). The mean (SD) total work time was much longer in the MCR group than in the control group (650 [145] minutes vs 439 [69] minutes, P < .001). There were no significant differences in gastric transit time, colon imaging time, and the diagnostic yield between the 2 groups. The sample size was small, although statistical significance of the primary outcome was achieved. However, this could have limited representativeness. Reduction of the capture rate of the OMOM capsule endoscope in the stomach increased the complete small-bowel examination rate, although the diagnostic yield was not increased in our patient setting.

Right lateral position improves complete examination rate of capsule endoscope: a prospective randomized, controlled trial

In 20% of patients, capsule endoscopes fail to reach the cecum within the 8-hour battery life. This is the most common cause of incomplete small-bowel examination. The aim of this study was to determine whether keeping patients in the right lateral position (RLP) improves the complete examination rate (CER) of the small bowel by reducing the gastric transit time (GTT) of the capsule. Patients were randomized into the RLP group (n = 30) or control group (n = 30). Patients in the RLP group were instructed to lie on their right side postingestion until the capsule had passed through the pylorus. The patients in the control group were free to walk or sit (upright position). The main outcomes were the CER and GTT between the groups. There was no significant difference in the sex, mean age, and indications between the two groups. The CER was significantly higher in the RLP group than in the controls (96.7% vs. 73.3%, P = 0.030). GTT was significantly shorter in the RLP group than in the control group (medians [range]: 32 [8-108] vs. 58 [9-208] minutes, P = 0.007). Small-bowel imaging time was significantly longer in the RLP group than in the control group (372 [135-425] vs. 292 [146-422] minutes, P = 0.039). There were no significant differences in the diagnostic yields between the two groups. Placing patients in the RLP after ingestion of the capsule endoscope and before the capsule enters the pylorus is a simple method to increase the CER of the small bowel by reducing the GTT of the capsule.

Complications, Complete Examination Rate and Gastrointestinal Transit Time of OMOM Capsule Endoscopy: An Analysis with 1,068 Cases

Background and Objective: A new wireless OMOM capsule endoscope (OMOM CE), developed by Jianshan Science & Technology (Group) Co., Ltd, Chongqing, China, has been widely used in China and in some areas of Southeast Asian and European countries. About 53,000 OMOM capsules have been ingested since 2004. However, there are few published studies that summarize OMOM capsule endoscopy on complications, complete examination small bowel rate (CER), gastric transit time (GTT), and small bowel transit time (SBTT) with large sample. Methods: A database was retrieved from the Jianshan Science & Technology Ltd. OMOM CE Database. The 1,068 cases were from 17 endoscopy centers that used the OMOM CE system in Mainland China. The complications, complete small bowel examination rate (CER), gastric transit time (GTT), small bowel transit time (SBTT), and total work time were recorded and analyzed. Results: The major complication of OMOM CE was capsule retention, which were seen in 23 patients (esophageal 4, gastric 9, afferent loop 1, small bowel retention 9). The overall retention rate was 2.15%. Four capsules retained in the small bowel were surgically removed, and the remainders were successfully removed by gastroscopy or double balloon enteroscopy. The overall CER of OMOM CE was 82.68%. In the 185 patients with uncompleted examination, the delayed gastric emptying was the major cause (68 patients' GTT >120 min, 36.8%). The CER was not related to the gender or age. The decrease in CER was positively related to the increase in GTT, and inversely related to the increase in total work time (TWT) of OMOM CE (Both p < 0.001). The CER in the non-OGIB group was greater than OGIB group (78.5% vs. 86.5% p < 0.001). The mean GTT, SBTT and TWT were 68 min (rang 1∼543 min), 261 min (rang 27∼690 min), and 468 min (rang 168∼911 min), respectively. Conclusions: This is the first large report on OMOM capsule endoscopy, and the capsule retention rate is very low and comparable with that of Given PillCam capsule system. The complete small bowel examination rate was 82.6%, which was related to gastric transit time and total work time of OMOM capsule, but not related to gender and age.

Right Lateral Position Improves Complete Examination Rate of Capsule Endoscope: A Prospective Randomized, Controlled Trial

Background and Aim: It has been reported that capsule endoscopes (CE) fail to reach the cecum in 20% of patients within the 8-hour battery life. The delayed gastric transit is the most common causes of incomplete small bowel examination. It's noted empirically that the gastric transit time (GTT) appeared to be decreased if patients were put in the right lateral position (RLP) post ingestion. The aim of this study was to determine whether RLP can improve complete examination rate (CER) of the small bowel by reducing the GTT of CE.
