RESUMO
Clinical cases treated by magnetic compression anastomosis (MCA) for different causes and types of intestinal stenosis/ atresia to successfully achieve intestinal recanalization were reviewed, so as to explore the clinical application of MCA. From May 2019 to August 2022, 4 patients underwent colorectal MCA for intestinal recanalization in the First Affiliated Hospital of Xi'an Jiaotong University and Northwest Women and Children's Hospital. All operations went well, and the intestinal anastomosis was recanalized. The magnetic ring was discharged in 7-15 days, and the postoperative colonoscopy or radiography showed that the anastomosis was intact. MCA can be used to treat different types of colorectal stenosis and atresia due to different reasons, and can also be used to assist intestinal anastomosis in colorectal surgery.
RESUMO
【Objective】 To study the diagnostic value of balloon expulsion test, anorectal manometry, and colonic transit test for detecting constipation with defecation disorders. 【Methods】 Outpatients with functional constipation were retrospectively analyzed and classified into dyssynergic defecation constipation and non-dyssynergic defecation constipation according to the Rome Ⅳ diagnostic criteria. We studied the differences in symptomatological characteristics and results of the three testing methods between the two groups of patients. 【Results】 Among the 48 patients with functional constipation included, there were 13 males (27.1%) and 35 females (72.9%) with an age of (44.8±12.3) years, including 32 patients (66.7%) with defecation disorder and 16 patients (33.3%) with non-defecation disorder. The percentage of anal distension was significantly higher in patients with dyssynergic defecation constipation than in those with non-dyssynergic defecation constipation (34.4% vs. 0.0%, P=0.021). All the three tests had diagnostic value for dyssynergic defecation constipation, but with low diagnostic agreement between the results of each test. The diagnostic sensitivity of anorectal manometry was 100%, but the specificity (56.3%) was low, and both the positive predictive value (82.1%) and the negative predictive value (100%) were higher; the diagnostic sensitivity (75.0%) and specificity (81.3%) of the balloon expulsion test were both higher. The Youden index of colonic transit test was the smallest. The anal resting pressure and maximum systolic pressure of dyssynergic defecation constipation were lower than those of non-dyssynergic defecation constipation (75.2 mmHg vs. 97.1 mmHg, 168.7 mmHg vs. 251.6 mmHg). The two types of constipation did not significantly differ in anorectal pressure gradients during simulated defecation or rectal sensory function. 【Conclusion】 The balloon expulsion test can be used as a primary screening test for constipation with defecation disorders, and anorectal manometry has the highest comprehensive diagnostic value, but there is a certain false positive rate, and the colonic transit test has the lowest diagnostic efficacy. Thus a comprehensive analysis of the patient’s symptoms and the results of different tests is needed in clinical practice.
RESUMO
Objective To explore the effect of cognitive education and behavioral intervention in solid-state high resolution esophageal manometry (HRM) examination. Methods From April 2016 to June 2017, 60 patients with solid-state HRM in the gastrointestinal motility room at the First Affiliated Hospital of Jiaotong University were as the research object. The 60 patients were divided into control group and experimental group with 30 cases each by the method of random numbers. The conventional methods was used in control group to conduct informed counseling before the examination and the coordination guidance in the examination. The conventional methods and cognitive behavioral intervention was used in experimental group at the same time. The successful rate of intubation, the time used for the examination, discomfort symptoms during intubation, the patient's satisfaction in the whole check process and self-evaluation of intubation pain experience in two groups of patients were compared. Results The time used in the experimental group examination was (28.50±8.75) min, and the control group was (33.13± 5.49) min. The difference between the two groups was statistically significant (t=2.584, P=0.015). In the experimental group, the number of nausea, vomiting, and coughing in the intubation process was 11, 0, and 1, respectively, and the control group was 20, 6, and 7, respectively. The difference was statistically significant (χ2=5.406, 4.630, 5.192, all P<0.05). In the experimental group, the scores of the 2, 3, 4, 5, 7, 8, 10, 11, 12, and 13 items of the intubation pain experience self-evaluation in the examination process were (1.00 ± 0.64), (1.37 ± 0.85), (2.80 ± 0.96), (1.50 ± 0.51), (0.87 ± 0.63), (0.77 ± 0.50), (0.60 ± 0.56), (1.07 ± 0.25), (0.57 ± 0.57), (1.50 ± 0.63) points, and the 2, 3, 4, 5, 7, 8, 10, 11, 12 and 13 scores of the control group they were (1.50 ± 0.51), (2.03 ± 0.76), (3.50 ± 0.82), (2.03 ± 0.76), (1.20 ± 0.61), (1.03 ± 0.41), (0.83 ± 0.53), (1.23 ± 0.43), (0.87 ± 0.57), (2.00 ± 1.05) points, respectively. The difference was statistically significant (t=-4.130--2.140, all P<0.05). Conclusions HRM is an important test before the clinical application of a wide range of clinical applications for the detection of esophageal motility disorders and gastroesophageal reflux disease. The degree of patient cooperation with the operation directly affects the high-resolution esophageal manometry test results and self-experience. Medical staff can give patients cognitive education and behavioral intervention before examination, which can effectively reduce the symptoms and pain caused by intubation, improve patient compliance, shorten the time for examinations, improve work efficiency, and improve patient satisfaction. It is worth further promotion and application in clinical examination.
RESUMO
BACKGROUND/AIMS: High-resolution anorectal manometry (HRAM) has been considered a first-line diagnostic tool for functional defecation disorder. However, clinical studies on HRAM used in constipation patients are very limited and few studies have reported the characteristics of anorectal pressure in Chinese patients. The aim of this study is to investigate the characteristics of motility data in a cohort of Chinese patients with functional constipation. METHODS: A total of 82 consecutive patients with functional constipation who underwent a standardized HRAM were retrospectively enrolled in this study. The functional defecation disorder was classified into Rao's types. RESULTS: The mean age of 82 patients was 51 years (range, 16–83 years). Indications for anorectal manometry were functional constipation for all patients. The mean resting pressure was 69.2 ± 21.2 mmHg (range, 24.5–126.9 mmHg). The mean maximum squeezing pressure was 198.4 ± 75.6 mmHg (range, 54.2–476.9 mmHg). The mean length of the anal high pressure zone was 3.4 ± 1.0 cm (range, 0.6–4.9 cm). Sixty (73.2%) patients were diagnosed as functional defecation disorder. In attempted defecation, type I was most common (n = 24), followed by type II (n = 12), type III (n = 11), and type IV (n = 13) that were present on HRAM according to Rao's classification. In all 60 patients with functional defecation disorder, 37 were women and 23 were men. Men were significantly more likely than women to have functional defecation disorder (92.0% vs 64.9%, P = 0.014). CONCLUSION: HRAM could be used as a test for the diagnosis of functional defecation disorder and functional defecation disorder is common in Chinese patients with functional constipation.
