ABSTRACT
Objective:To evaluate the clinical efficacy of endoscopic treatment for early nonampullary duodenal cancer.Methods:Data of patients with early nonampullary duodenal cancer, who underwent endoscopic treatment from January 2015 to January 2021 at Beijing Friendship Hospital were retrospectively analyzed. Baseline data, endoscopic treatment methods, wound closure, pathology, the occurrence and outcome of complications of patients were studied.Results:A total of 47 patients who successfully went through endoscopic treatment were enrolled. Seventeen cases received endoscopic mucosal resection (EMR), 5 cases received endoscopic submucosal dissection (ESD), and 7 cases received ESD+EMR (hybrid ESD). Six cases were converted to hybrid ESD due to difficulty in ESD. Four cases received full-thickness resection with over-the-scope clip system (OTSC), and 8 cases received endoscopic piecemeal mucosal resection (EPMR). Among the 47 cases of early cancer, the en bloc resection rate was 83.0% (39/47), and the complete resection rate was 85.1% (40/47). Four patients (8.5%) had perforation which occurred at the duodenal descending part during the perioperative period, among whom, 2 patients (4.3%) recovered after endoscopic treatment, 2 others (4.3%) recovered after surgical intervention. There were no complications such as postoperative bleeding or infection during the perioperative period.Conclusion:Endoscopic treatment for early nonampullary duodenal cancer is safe and effective. A specific treatment plan can be selected according to the location, size and specific conditions of the lesion. For the operation of the descending part, it is necessary to be more vigilant to against the occurrence of perforation complications.
ABSTRACT
Objective:To evaluate the clinical efficacy of endoscopy for early cancer of duodenal papilla.Methods:A retrospective analysis was performed on data collected from 23 consecutive patients with early cancer of duodenal papilla, who underwent endoscopic treatment from January 2015 to January 2021 in Beijing Friendship Hospital. Baseline data, endoscopic and pathological data, occurrence and outcome of complications were studied.Results:Twenty-three patients successfully received endoscopic treatment. The maximal diameter of lesions evaluated under endoscopy was 1.90±0.83 cm. Among the 23 cases, 20 underwent endoscopic mucosal resection and 3 underwent endoscopic piecemeal mucosal resection. Delayed bleeding occurred in 5 cases (21.7%), 3 patients (13.0%) developed postoperative hyperamylasemia, 6 patients (26.1%) developed mild acute pancreatitis, and 1 patient (4.3%) had pancreatic duct stent displacement after the operation, which improved after medical or endoscopic treatment. No perforation occurred during the perioperative period. In terms of final pathology, the en bloc resection rate was 82.6% (19/23), and the complete resection rate was 78.3% (18/23). Preoperative endoscopic ultrasonography showed that 19 lesions were confined to the mucosal layer, which were all demonstrated by postoperative pathology. Four other cases were suspected to be involved in the submucosa or the end of the pancreaticobiliary duct under endoscopic ultrasonography, two of which were confined to the mucosal layer, and the other 2 cases involved the submucosal layer, so additional surgery was performed. A total of 18 patients were followed up, among whom 14 achieved complete resection of postoperative pathology, and 2 patients (14.3%, 2/14) were found to have recurrence at 12 and 51 months respectively after the treatment and did not relapse after surgical treatment and endoscopic treatment respectively. Among 4 other patients of follow-up whose pathology did not achieve complete resection, 1 had no recurrence, and the other 3 received additional surgical treatment without recurrence.Conclusion:Endoscopic treatment for early cancer of duodenal papilla is safe and effective. It is necessary to improve preoperative evaluation, stay alert to perioperative complications, and pay attention to regular postoperative endoscopic follow-up.
ABSTRACT
Objective:To evaluate the efficacy and safety of rubber band traction-assisted endoscopic submucosal dissection (ESD).Methods:A total of 49 patients with rectal endocrine tumor who underwent ESD at Beijing Friendship Hospital Affiliated to Capital Medical University from January 2016 to December 2019 were reviewed. Thirty-two patients who underwent traditional ESD from January 2016 to May 2018 were assigned to the non-traction group. Seventeen patients who underwent the operation with a rubber band as auxiliary traction from June 2018 to December 2019 were assigned to the traction group. Basic information, ESD procedure time, complications were compared between the two groups.Results:There were no significant differences in age, gender or lesion size between the traction group and the non-traction group ( P>0.05). The ESD operation time of the traction group was significantly shorter than that of the non-traction group (13.76±5.71 min VS 22.99±10.32 min, t=-3.408, P=0.001). There were no postoperative complications in the traction group, but 3 cases of perforation occurred in the non-traction group. There was no significant difference in the incidence of perforation between the two groups ( P=0.542). Conclusion:Rubber band traction can safely improve the efficiency of ESD.
ABSTRACT
Huge improvement has been made in the diagnosis and treatment of endoscopic ultrasonography (EUS) and more doctors have begun to focus on this subject with the increased level of EUS. Beijing Friendship Hospital has built a comprehensive system for the teaching method and process which include basic information screening of trainee and standardized training of perceiving and operating ability. There were 3 grades training of computer simulation, animal simulation and operation on real patients. During the first month of training, trainees accepted training with computer simulator for at least 100 hours, and underwent animal simulator during the second month, then underwent EUS on the real patients under supervision of instructors during the third month. By doing this, residents can master the technique of treatment and diagnosis of EUS in a safer and better way.
ABSTRACT
Objective:To investigate the risk factors for prolonged procedure time of endoscopic submucosal dissection (ESD) for colorectal laterally spreading tumors (LSTs).Methods:Consecutive patients who underwent ESD for colorectal LSTs at Beijing Digestive Disease Center from June 2013 to March 2019 were retrospectively analyzed. Univariate analysis was used to identify factors associated with prolonged procedure time (≥60 min). Factors with significant difference in univariate analysis were included in multivariate logistic regression to determine the independent risk factors.Results:A total of 201 patients (age 65.05±10.44 years old, 53.73% were males) with 213 LSTs (diameter 2.52±1.67 cm) were included. En bloc resection rate, complete resection rate and curative resection rate were 93.90%, 84.04% and 79.81%, respectively. Intraoperative perforation rate, delayed perforation rate and delayed bleeding rate were 1.88%, 0.94% and 1.41%, respectively. Diameter ≥3 cm ( OR=13.48, P<0.001), granular nodular mixed (G-NM) subtype ( OR=25.28, P=0.002), granular homogenous subtype ( OR=9.00, P=0.045), location of rectosigmoid ( OR=3.08, P=0.002) and positive non-lifting sign ( OR=3.40, P=0.012) were associated with longer procedure time in univariate analysis. In multivariate logistic regression, diameter ≥3 cm ( OR=9.29, P<0.001), G-NM subtype ( OR=8.80, P=0.043) and positive non-lifting sign ( OR=3.43, P=0.043) were independent risk factors for prolonged procedure time. Longer procedure time was associated with lower rates of complete resection (69.56% VS 88.55%, P=0.003) and curative resection (63.64% VS 85.50%, P=0.002), and increased rate of carcinoma (86.96% VS 51.91%, P<0.001). Conclusion:LSTs of size over 3 cm, G-NM subtype or positive non-lifting sign predict prolonged procedure time, which is associated with reduced efficacy of ESD and higher risk of carcinoma.
ABSTRACT
Objective:To investigate the independent predictors for malignancy in colorectal laterally spreading tumors (LSTs) by therapeutic endoscopy.Methods:Data of consecutive patients with colorectal LSTs who underwent endoscopic treatment in Beijing Friendship Hospital between June 2013 and March 2019 were collected for retrospective analysis. Patients′ gender, age, body mass index, smoking history, and endoscopic and histological results were reviewed. Univariate analysis was used to identify the associated factors for malignancy of colorectal LSTs. Factors with statistical significance in univariate analysis were used in multivariate logistic regression to determine the independent predictors.Results:A total of 323 patients with 341 colorectal LSTs were involved in the study. The rate of malignancy was highest in non-granular pseudo depressed (NG-PD) subtype [85.48% (53/62)], followed by granular nodular mixed (G-NM) subtype [76.97% (117/152)]. Both of the above rates were significantly higher than that of granular homogenous (G-H) subtype [29.51% (18/61), P<0.001] and non-granular flat elevated (NG-FE) subtype [24.24% (16/66), P<0.001]. Univariate analysis showed that NG-PD subtype ( P<0.001, OR=18.40, 95% CI: 7.46-45.42), G-NM subtype ( P<0.001, OR=10.45, 95% CI: 5.30-20.58), rectosigmoid location ( P<0.001, OR=2.33, 95% CI: 1.47-3.69) and size ≥2 cm ( P<0.001, OR=2.60, 95% CI: 1.60-4.00) associated with malignancy for colorectal LSTs. In multivariate logistic regression, NG-PD subtype ( P<0.001, OR=17.51, 95% CI: 7.06-43.43), G-NM subtype ( P<0.001, OR=8.25, 95% CI: 4.07-16.73) and size ≥2 cm ( P=0.032, OR=1.80, 95% CI: 1.05-3.08) remained to be independent predictors. Conclusion:LSTs of NG-PD subtype, G-NM subtype or size ≥2 cm are high risk factors of malignancy, in which cases, en bloc resection is required.
ABSTRACT
Objective To study the therapeutic value of endoscopy for primary duodenal lesions. Methods Data of 79 consecutive patients with primary duodenal lesions, who underwent endoscopic treatment from January 2015 to January 2018 at Beijing Friendship Hospital, were retrospectively analyzed. Patients were divided into the complication group and the non-complication group, and further grouped according to lesion locations and endoscopic categories. Baseline data of patients, endoscopic treatment, wound closure method, pathological results, the occurrence and outcome of complications were studied. Results A total of 79 patients successfully went through endoscopic treatment, including 59 cases of endoscopic mucosal resection ( EMR) , 5 cases of endoscopic submucosal dissection ( ESD) , 6 cases of full-thickness resection with OTSC metal clips, and 9 cases of endoscopic piecemeal mucosal resection ( EPMR) . In all 79 cases, complications occurred in 8 patients ( 10. 1％) during the perioperative period, all at the duodenal descending segment and duodenal papilla. In all 47 cases whose lesions located at duodenal papilla and duodenal descending segment, the complication incidence was 17. 0％ ( 8/47) , significantly higher than that of non-descending and papilla part [ 0 ( 0/32 ) , P=0. 012 ] . Two ( 2. 5％) cases had complications requiring further intervention with endoscopy or surgery. Among 8 patients with complications, 1 patient ( 2. 1％) developed intraoperative perforation, 1 patient ( 2. 1％) developed delayed bleeding, 6 patients ( 12. 8％) developed mild acute pancreatitis, and these 8 patients recovered after treatment. These 47 patients were further divided into the duodenoscopy group and the gastroscopy group according to endoscopic categories, the complications incidence in the duodenoscopy group ( 28. 0％, 7/25) was also significantly higher than that in the gastroscopy group [ 4. 5％( 1/22) , P=0. 037] . Conclusion Endoscopic treatment is safe and effective for primary duodenal lesions. But for the operations in the duodenal descending segment and the duodenal papilla, as well as in the case of duodenoscopy, it is necessary to be more vigilant about the occurrence of complications.
ABSTRACT
Objective To evaluate the clinical and esophageal dynamics characteristics, and initial treatment effect of patients with untreated achalasia using high resolution manometry. Methods From January 2012 to June 2016, patients newly diagnosed with achalasia were retrospectively recruited. Clinical information, endoscopy and X-ray findings, manometric variables and treatment outcomes were collected and compared among manometric subtypes. Results Among 133 patients with achalasia, 32 ( 24. 0%) were classified as type Ⅰ, 84 ( 63. 2%) as typeⅡ and 17 ( 12. 8%) as typeⅢ. Compared with the typeⅢ, the symptom of regurgitation was more common in the types I and typeⅡachalasia patients ( P=0. 020) . While compared with the type Ⅰ, the score of chest pain was higher in the patients with type Ⅱ and type Ⅲ ( P=0. 006) , as well as the basal lower esophageal sphincter pressure ( P=0. 015, P=0. 023 for type Ⅱ and type Ⅲ, respectively) . Integrated relaxation pressure was similar among the 3 subtypes ( P=0. 158) . Forty-five and 47 patients received pneumatic dilation ( PD ) and peroral endoscopic myotomy ( POEM ) respectively, and all of the patients were followed-up for at least 6 months. The success rate was higher in the POEM group than that of the PD group in all the 3 manometric subtypes, but only the difference between POEM and PD in the type Ⅲ was statistically significant ( 90. 0% VS 40. 0%, P = 0. 041 ) . Conclusion The clinical characteristics and treatment response are different among the 3 achalasia subtypes. Patients with type Ⅲ achalasia are probably the best candidates for POEM.

ABSTRACT
Objective To investigate the efficacy of acupuncture combined with doctor-nurse cooperation mode on stroke-associated pneumonia in patients with acute stroke. Methods 67 patients of acute stroke within 1 week in our hospital from March, 2013 to January, 2015 were randomly divided into control group (n=35) and treatment group (n=32). Both groups received neurological routine treatment and systematic rehabilitation training by professional physiotherapists under general nursing mode. The treatment group received acupuncture treatment under doctor-nurse cooperation mode additionally. Incidence of stroke-associated pneumonia, swallow function and aspiration rate were recorded. Results Compared with the control group, the incidence of stroke-associated pneumonia significantly decreased in the treat-ment group after treatment (χ2=4.615, P=0.032). The retention volume of epiglottic vallecula and pyriform sinus (tdilute barium=21.01, tthick barium=19.85), the duration of pharynx period (tdilute barium=17.03, tthick barium=13.68), and the start time of pharynx period (tdilute barium=19.63, tthick barium=17.86) were less in the treatment group than in the control group (P0.05). Conclusion Acupuncture combined doctor-nurse cooperation mode may decrease the rates of aspiration and stroke-associated pneumonia in acute stroke patients through improving their swallow function.
ABSTRACT
Objective To explore the value of computer-animal-clinic sequential training model in colonoscopy training.Methods Sixty-five gastroenterologists without any experience in colonoscopy were randomly assigned to 2 groups to accept a two-week′endoscopy training with computer simulator or with com-puter-animal-clinic sequential training.Both groups underwent at least 10 hours of training with a computer-based simulator,and sequential training group also underwent animal simulator training for 2 days in first week,then both groups underwent clinical endoscopy training in the second week.Performance parameters including cecal intubation,procedure duration and degree of comfort were evaluated.Results The training group had higher cecal intubation rate (46.28% VS 35.79%;P <0.01 )and shorter procedure duration (9.05 ±2.12 min VS 11.15 ±3.12 min;P <0.05)and less degree of comfort (5.18 ±1.41 VS 6.78 ± 2.15;P <0.05).The sequential training group was much better in performance than the other group in colonoscopy training.Conclusion Computer-animal-clinic sequential training model is effective in providing trainees with colonoscopy skills in improving the success rate,shortening the teaching times and lessening the uncomfortable of patients.
ABSTRACT
Objective To observe the effect of acupuncture combined with moxibustion on heart rate variability (HRV) in patients with post-stroke depression. Methods 120 patients were divided into control group (n=60) and treatment group (n=60). Both groups took fluox-etine and accepted acupuncture therapy, and the treatment group accepted moxibustion additionally. Hamilton Depression Rating Scale-17 (HAMD-17) and the change of HRV were compared before and after treatment. Results The score of HAMD was lower, and the reductive ratio was higher in the treatment group than in the control group (P<0.05). The standard deviation of the mean of qualified normal sinus in-terval (SDNN) and standard deviation of sequential five-minute R-R interval means (SDANN) increased in both groups after treatment (P<0.05), and were higher in the treatment group than in the control group (P<0.05). The root mean square differences of successive R-R inter-vals (RMSSD) and percentage of differences between adjacent normal sinus intervals greater than 50 ms (PNN50) decreased in both groups after treatment (P<0.05), and were lower in the treatment group than in the control group (P<0.05). The low frequency (LF), high frequency (HF) and LF/HF were higher in both groups after treatment (P<0.05), and were higher in the treatment group than in the control group (P<0.05). Conclusion Acupuncture combined with moxibustion therapy can better adjust the function of autonomic nerve and reduce depres-sion in patients with post-stroke depression.

ABSTRACT
Objective To evaluate the efficacy and safety of fluoroscopy guided frequency-doubled double-pulsed laser lithotripsy for removing difficult bile duct stones. Methods From March 2008 to December 2009, patients with difficult bile duct stones were divided into cholangioscopy guided group ( n = 21 )and fluoroscopy guided group ( n = 19) to receive corresponding treatments. The success rate of complete stone removal and the complication rate related to the procedure were compared between the two groups.Results There are no significant differences between 2 groups in regarding of either success rate of complete stone removal ( 19/21, 90. 5% in cholangioscopy guided group vs. 17/19, 89. 5% in fluoroscopy guided group, P ＞0. 05 ) or rate of procedure related complication (4/21, 19. 0% in cholangioscopy guided group vs. 3/19, 15. 8% in fluoroscopic guided group, P = 0. 559 ). Conclusion Frequency-doubled doublepulsed laser lithotripsy guided by cholangioscopy or fluoroscopy are both safe and effective.
ABSTRACT
Objective To evaluate the efficacy and safety of endoscopic mucosal resection (EMR) for rectal carcinoid tumors. Methods From January 2006 to January 2009, EMR was performed in 28 patients with rectal carcinoids, who were followed up to evaluate the therapeutic effect and safety. Results Tumor diameters varied from 0.4 cm to 1. 2 cm (mean 0.7± 0. 2 cm). Negative resection margin was a-chieved in 26 cases (92. 9% ), tumor margin within 0. 1 cm of resection margin in 1 (7. 1% ) , and two margins coincided in 1 patient (7. 1% ). Hemostasis was performed with metal clips in 14 patients (50% ) and argon plasma coagulation (APC) in 9 (32. 1% ). Except for rectal bleeding in 1 patient (3. 6% ) , no other complications were observed. There was no recurrence in any patients during a follow-up of 6-36 months. Conclusion EMR is a useful and safe method for treatment of small rectal carcinoid tumor which does not cross submucosal layer.
