ABSTRACT

Objective:To investigate the relationship between the cardia morphology under magnetically controlled capsule gastroscopy and the clinical characteristics of subjects.Methods:A total of 216 subjects with gastrointestinal symptoms or receiving physical examination who underwent magnetically controlled capsule gastroscopy at the Department of Gastroenterology, Beijing Chao-Yang Hospital, Capital Medical University from August 2022 to November 2022 were enrolled. All subjects took gastroesophageal reflux disease questionnaire (Gerd-Q) survey. Clinical data of subjects were collected, and images of cardia morphology under magnetically controlled capsule gastroscopy were recorded. The subjects were divided into 4 groups according to differrent cardia morphology based on the degree of relaxation. The clinical characteristics of each group were compared, and the influencing factors for cardia morphology were analyzed.Results:In non-swallowing state, 116 subjects showed good continuous closure of the cardia in plum shape (group A), 33 subjects radial closure of cardia (group B), 46 subjects slightly relaxed linear cardia (group C) and 21 subjects relaxed and continuous opening of cardia in the shape of cave (group D). The ages of subjects in group A, B, C and D were 35.00 (31.00, 42.00) years, 53.00 (37.50, 60.50) years, 61.50 (41.50, 68.25) years and 52.00 (39.00, 70.00) years, respectively, with significant differences ( H=44.348, P<0.001). The Gerd-Q scores of subjects in group A, B, C and D were 1.50 (1.00, 2.00), 3.00 (2.00, 6.50), 8.00 (5.75, 9.00) and 8.00 (7.50, 9.00), respectively, with significant differences ( H=90.788, P<0.001). The body mass index (BMI) of subjects in group A, B, C and D were 22.66 (19.53, 24.70) kg/m 2, 23.44 (21.41, 27.05) kg/m 2, 23.77 (21.19, 26.93) kg/m 2 and 23.73 (19.63,24.79) kg/m 2, respectively, with significant differences ( H=8.114, P=0.044). The degree of cardia relaxation was positively correlated with the age ( rs=0.456, P<0.001), Gerd-Q score ( rs=0.648, P<0.001) and BMI ( rs=0.146, P=0.032) of subjects. Conclusion:The magnetically controlled capsule gastroscopy provides good visualisation of cardia morphology in non-swallowing state. There is a positive correlation between the degree of cardia relaxation under magnetically controlled capsule gastroscopy in non-swallowing state and the subjects' age, Gerd-Q score, and BMI.

ABSTRACT

Objective:To investigate the characteristics of endoscopic ultrasonography for rectal neuroendocrine neoplasms (R-NENs) of different origin and its influence on the diagnosis and treatment.Methods:A retrospective cross-sectional study was conducted to analyze 56 cases of R-NENs diagnosed by miniprobe endoscopic ultrasonography (MEUS) and/or pathology in the Endoscopy Center of Beijing Chaoyang Hospital, Capital Medical University from January 2016 to July 2021. The endoscopic ultrasonography characteristics, pathological features, surgical selection and the follow-up of R-NENs originating from deep mucosa and submucosa were compared.Results:Among the 56 patients, 49 were diagnosed as R-NENs.The diagnostic sensitivity, positive predictive value and diagnostic accuracy of MEUS for R-NENs were 93.88% (46/49), 86.79% (46/53) and 82.14% (46/56), respectively. R-NENs were mainly manifested by medium hypoechoic with MEUS [95.92% (47/49)]. Three R-NENs originated from submucosa were missed diagnosis, with 1 case presenting hypoechoic and 2 cases presenting hyperechoic. There were no significant differences in the tumor diameter, echo intensity under endoscopic ultrasonography, echo uniformity and pathological grade composition between deep mucosal origin and submucosal origin R-NENS (all P>0.05), but there was significant differences in the distance from tumor to anus ( χ2=5.011, P=0.025). The proportion of the distance from tumor to anus ≤5 cm of submucosal origin lesions was significantly higher than that of deep mucosal origin [43.75% (14/32) VS 17.65% (3/17)]. Endoscopic submucosal dissection [67.5% (27/40)] and transanal endoscopic microsurgery [25.0% (10/40)] were the major treatment method, but there were no significant differences in endoscopic ultrasonography manifestations and pathological grading of R-NENs between these two surgical procedures. Conclusion:There is no significant difference in endoscopic ultrasonography manifestations and pathological grade of R-NENs between deep mucosal origin and submucosal origin, suggesting that the prognosis is similar between the two types. It is no significant influence of endoscopic ultrasonography manifestations of R-NENs at different levels of origin.

ABSTRACT

Objective:To investigate the clinical application value of magnetically controlled capsule endoscopy (MCCE) for risk assessment of upper gastrointestinal bleeding in elderly patients taking enteric-coated aspirin.Methods:Clinical data of elderly patients taking enteric-coated aspirin and undergoing MCCE from January 2018 to December 2020 in Beijing Chaoyang and Beijing Anzhen Hospital, Capital Medical University were analyzed. Patients were divided into low-risk group (scores ≤ 3) and moderate/high risk group (scores >3) to study the risk assessment of upper gastrointestinal bleeding in elderly patients taking enteric-coated aspirin.Results:A total of 66 patients (aged 60-81 years, 45 males and 21 females) were enrolled and 17 patients developed bleeding. The indicators of low-risk ( n=51) and moderate/high risk groups ( n=15) were as follows: the incidences of upper gastrointestinal bleeding were 17.6% and 53.3%( P<0.001), gastric ulcer 5.9% and 26.7% ( P<0.001), median gastric Lanza score 2.0 and 2.0( P=0.621), duodenal ulcer 2.0% and 18.8% ( P<0.001), median duodenal mucosal injury score 1.0 and 1.0( P=0.936), respectively. Receiver operator characteristic curve showed that the area under the curve of risk assessment of upper gastrointestinal bleeding in elderly patients taking enteric-coated aspirin by MCCE was 0.855. Conclusion:Risk assessment of upper gastrointestinal bleeding in elderly patients taking enteric-coated aspirin can be used to predict the risk of upper gastrointestinal bleeding, but the scoring rules need to be further improved. Moderate and high-risk patients should undergo MCCE to monitor aspirin related upper gastrointestinal mucosal injury.

ABSTRACT

Objective We discussed the optimal method for intestinal preparation before colonoscopy examination in order to increase the success rate of intestinal examination and reduce the incidence of adverse effect. Methods We divided 120 patients who were to undergo colonoscopy examination into group A, B and C with 40 cases in each group. Group A received oral magensium sulfate 100ml and 6000ml water after that on the morning of the examination. Group B received oral magensium sulfate 50ml and 2000ml in the evening before the examination, oral magensium sulfate 50ml and 400ml water on the morning of the examination. Group C was given oral magensium sulfate 100ml and 4000~5000 water at the same time. Group A and B took part in appropriate activity and were given health education. The effect of intestinal preparation was compared between the three groups. Results The cleaning degree of group B was better than those of the other two groups (P<0.05). The adverse effect of group B was less than that of group C (P<0.01). Conclusions Oral intake of magensium sulfate in the evening before and on the morning of the examination for intestinal preparation could increase the cleaning degree of intestine, facilitate the observation of disease part and lessen adverse effect. It gave satisfying examination results and made patients satisfied.
