OBJECTIVETo compare the safety and efficiency of transverse-incision peroral endoscopic myotomy (POEM) with longitudinal-incision POEM.

METHODSPOEM, with a transverse or longitudinal entry incision, was performed in 53 consecutive patients with confirmed achalasia (AC) between December 2010 and September 2012. Data of those patients was collected including the time spent for different procedures and complications.

RESULTSAll the 53 patients underwent POEM successfully, among whom 41 patients had a transverse entry incision and 12 had a longitudinal incision. Treatment success (Eckardt score≤3) with a follow-up for 3-24 months (median 5 month) was achieved in 96.2% of the cases (mean score pre-treatment vs. post-treatment: 7.5 vs 0.6, P<0.001). The whole operation time of transverse-incision group was slightly shorter than that of longitudinal-incision group (65.0∓18.0 min vs 74.1∓18.2 min, P=0.142), but it took much less time in tunnel built-up and muscle dissection in the transverse-incision group (36.3∓9.0 min vs 45.4∓10.5 min; 10.2∓4.6 min vs 15.5∓5.5 min, P<0.05). In addition, patients in transverse incision group were much less likely to develop pneumatosis- related complications [9.8% (4/41) vs 41.7% (5/12), P<0.05). No serious complications occurred in these two groups such as pleural effusion, mediastinitis or digestive tract fistula.

CONCLUSIONSPOEM with a transverse entry incision can significantly decrease the operation time and reduce the incidence of pneumatosis-related complications while obviously relieving the symptoms.

OBJECTIVETo evaluate the effects of compound whole grain-soybean on insulin resistance and serum adipocytokines levels in impared fasting glucose population.

METHODSAccording to inclusion and exclusion criteria, 163 cases of impared fasting glucose (IFG) Chinese Han population from the age of 40 to 75 years old, were screened from 12 community health centers of three main districts of Nanjing city by the multi-stage cluster and simple randomization method from March to September, 2008. The IFG subjects were randomly divided into the intervention group (87 individuals) and control group (76 individuals) by quasi-experimental design. The intervention group was provided with compound whole grain-soybean and health education, while only health education was provided for the control group. Body mass index (BMI), waist-to-hip ratio (WHR), lipid profiles, fasting blood glucose (FBG), fasting insulin (FINS) and homeostasis model assessment of insulin resistance (HOMA-IR), adipocytokines including leptin, lipocalin 2 (LCN-2) and adiponectin (ADP) levels were measured before and after the half a year intervention period. Chi square test was used to analyze the distribution differences. Two-sample t-test was used to compare the differences of the two groups before and after the half a year intervention period, and paired t-test was used to compare the differences between before and after intervention in the intervention group or control group. Wilcoxon rank sum test was used to compare the differences of all indexes between after and before dietary intervention.

RESULTSAfter dietary intervention for half a year on the IFG population, BMI ((24.87 ± 3.69) kg/m(2)), FBG((6.27 ± 0.24) mmol/L), FINS((7.14 ± 1.05) mU/L) , HOMA-IR (1.99 ± 0.31), leptin ((13.07 ± 2.22) µg /L), LCN-2 ((67.42 ± 18.20) µg/L) of intervention group were decreased significantly compared to the levels of BMI ((25.16 ± 4.07) kg/m(2)), FBG((6.40 ± 0.28) mmol/L), FINS ((7.32 ± 1.54) mU/L), HOMA-IR (2.08 ± 0.45), leptin ((13.43 ± 2.52) µg/L), LCN-2((74.87 ± 17.81) µg/L) before dietary intervention, t values were 4.48, 7.08, 2.05, 3.39, 3.28 and 6.36, respectively, and all P values were < 0.05, while ADP ((5.07 ± 1.51) mg/L) of intervention group after dietary intervention was increased significantly compared to the level of ADP ((4.92 ± 1.53) mg/L) before dietary intervention, t = -2.47 and P < 0.05. The medians (P25, P 75) of differences after and before dietary intervention in the intervention group were BMI (-0.25(-0.68, 0.02) kg/m(2)), FBG (-0.08 (-0.20, 0.00) mmol/L), FINS (-0.15(-0.32, 0.00) mU/L), HOMA-IR (-0.07(-0.12, -0.03)), leptin (-0.36(-0.77, 0.12) µg/L), LCN-2 (-5.85(-14.29, -0.71) µg/L) and ADP (0.15(-0.13, 0.36) mg/L), and the medians of differences of after and before dietary intervention in the control group were BMI (0.00(-0.23, 0.29) kg/m(2)), FBG (0.00(-0.03, 0.04) mmol/L), FINS (-0.01(-0.13, 0.04) mU/L), HOMA-IR (-0.01(-0.05, 0.02)), leptin (-0.07 (-0.57, 0.46) µg/L), LCN-2 (-0.85(-5.39, 1.63) µg/L) and ADP (0.02(-0.19, 0.13) mg/L). There were significantly statistical differences between them (Z values were -3.65, -4.88, -3.08, -5.23, -2.16, -4.43 and 3.05, all P values were <0.05).

CONCLUSIONDietary intervention of compound whole grain-soybean can improves glucose level, increase insulin sensitivity and ameliorate insulin resistance state of IFG population.

Objective:To investigate the predictive value of F-2-fluoro-2-deoxy-D-glucose ( 18F-FDG) PET-CT metabolic parameters for the recurrence of type 1 autoimmune pancreatitis (AIP). Methods:Eighty-six patients with type 1 AIP who met the International Consensus Diagnostic Criteria (ICDC) and underwent 18F-FDG PET-CT before interventional treatment at the PLA General Hospital between May 2009 and June 2021 were included and divided into recurrence group ( n=43) and no-recurrence group ( n=43) according to whether they recurred after treatment. The standard uptake value (SUV)≥2.5 fixed threshold was used to outline the pancreatic lesion volume of interest (VOI) in three dimensions, and the three-dimensional diameter of the lesion, maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), peak standardized uptake value (SUVpeak), metabolic tumor volume (MTV), total lesion glycolysis (TLG), target-to-bench ratio (TBR) and standardized uptake value ratio (SUVR) were measured to compare the clinical characteristics, biochemical indices and treatment of the two groups; univariate and multifactorial regression analysis were used to examine 18F-FDG PET/CT visual indices of pancreatic lesions and extra-pancreatic involved organs as well as metabolic parameters in the two groups. A recurrence prediction model was constructed and its predictive efficacy was assessed. Results:The proportion of patients receiving glucocorticoid maintenance therapy was significantly higher in the no-recurrence group than in the recurrence group (58% vs 23.3%), and the serum IgG4 levels before treatment were significantly higher in the recurrence group [(15 309±11 724) mg/L vs (8 816±7 169) mg/L]. The results of univariate analysis showed that the proportion of extra-pancreatic salivary gland involvement and VOI, SUVmax, SUVpeak, SUVR, TBR, MTV, and TLG were significantly higher in the recurrence group than in the no-recurrence group, and the differences were statistically significant (all P values <0.05); the results of multivariate analysis showed that VOI ( OR=1.012, 95% CI 1.001-1.023 ), SUV max ( OR=1.398, 95% CI 1.029-1.899), SUV peak ( OR=1.408, 95% CI1.002-1.978), SUVR ( OR=1.977, 95% CI1.036-3.771) and MTV ( OR=1.012, 95% CI1.000- 1.022) in the recurrence group were significantly higher than those in the no-recurrence group, and all differences were statistically significant (all P values <0.05). The prediction model was constructed by multifactorial binary logistic regression analysis of SUVR>2, MTV>36 cm 3, and IgG4>11 400 mg/L, which had an AUC of 0.800 (95% CI 0.704-0.897), sensitivity of 81.4% (95% CI 0.661-0.911), specificity of 74.4% (95% CI 0.585-0.860), and prediction accuracy of 77.9%. Conclusions:18F-FDG PET/CT metabolic parameters can be used as predictors of type 1 AIP recurrence; a multiparameter model constructed based on metabolic parameters SUVR, MTV and IgG4 has a good predictive efficacy for predicting type 1 AIP recurrence.

Objective:The effect of serum thyrotropin receptor antibody (TRAb) on permanent hypothyroidism (HT) after 131I treatment in Graves disease patients and its predictive value Methods:479 Graves' disease patients who underwent 131I treatment at the Nuclear Medicine Department of North China University of Technology Affiliated Hospital from October 2013 to October 2021 were selected. Among them, 350 cases (permanent HT group) had permanent HT during follow-up, while 129 cases (non permanent HT group) did not. Collect general clinical data such as gender, age, degree of thyroid enlargement, as well as indicators such as iodine intake rate, thyroid function, and treatment dose 24 hours before treatment, from two groups of patients. Compare the general clinical data and pre treatment levels of various detection indicators between two groups of patients, analyze the risk factors for permanent HT in Graves disease patients after 131I treatment, and evaluate the predictive value of pre treatment serum TRAb levels, and evaluate the consistency between the predicted results and clinical diagnosis. The econometric data with a normal distribution is represented by xˉ± s, and two independent sample t-tests are used for comparison between the two groups; The econometric data that do not conform to the normal distribution are represented by M（ Q1， Q3）, and the Wilcoxon rank sum test is used for comparison between the two groups; The counting data is represented as an example (%), and the comparison between the two groups is conducted using the four grid χ 2 test, while the comparison of grade data is conducted using the Willcoxon rank sum test; The logistic regression model was used for multivariate analysis. Draw a subject work characteristic curve to evaluate the predictive efficacy of TRAb, and screen the predictive threshold based on the Chayoden index; Calculate sensitivity and specificity, and evaluate the consistency between the predicted results and clinical diagnosis by calculating Kappa values. Results:There were no statistically significant differences in gender, age, degree of thyroid enlargement, 24-hour iodine uptake rate, serum thyroid stimulating hormone, free triiodothyronine, free thyroxine levels, and 131I treatment dose between the permanent HT group and the non permanent HT group (all P>0.05); The pre treatment TRAb levels in the permanent HT group were higher than those in the non permanent HT group [14.51(4.95,33.58) U/L vs 3.40(1.67,16.5) U/L], with a statistically significant difference ( Z=5.87, P<0.001). The results of multivariate logistic regression analysis showed that pre treatment TRAb levels were a risk factor for permanent HT in Graves' disease patients after 131I treatment (odds ratio=1.042,95% confidence interval: 1.025-1.059, P<0.001). The area under the working characteristic curve for predicting permanent HT in Graves' disease patients after 131I treatment with pre-treatment TRAb levels is 0.674 (95% confidence interval: 0.616~0.732), and the optimal critical value is 7.025 U/L. Using TRAb>7.025 U/L before treatment as the standard for predicting postoperative permanent HT in patients, the sensitivity and specificity were 73.7% and 75.2%, respectively. The predicted results showed moderate consistency with clinical diagnosis ( Kappa=0.426). Conclusions:The pre treatment TRAb level is a risk factor for permanent HT in Graves disease patients after 131I treatment ( P<0.001), and the diagnostic efficacy of permanent HT is best when TRAb>7.025 U/L.

OBJECTIVETo compare the safety and efficiency of endoscopic submucosal tunnel dissection (ESTD) and endoscopic submucosal dissection (ESD) for large esophageal superficial neoplasms.

METHODSA total of 235 consecutive patients undergoing endoscopic resection for esophageal neoplasms between October, 2010 and June, 2013 in our endoscopy center were analyzed retrospectively. According to the inclusion and exclusion criteria, 29 patients receiving ESTD or ESD for large esophageal superficial neoplasms were enrolled for data analysis.

RESULTSOf the 29 patients, 11 underwent ESTD and 18 received ESD. The dissection speed of ESTD was significantly higher than that of ESD (22.4∓5.2 mm(2)/min vs 12.2∓4.0 mm(2)/min, P<0.05). Despite a similar en bloc rate between the two groups (100% [11/11] vs 88.9% [16/18], P>0.05), the radical curative rate of ESTD was significantly greater than that of ESD (81.8% [9/11] vs 66.7% [12/18], P<0.05). No serious bleeding or perforation occurred in the patients except for 1 in ESD group with intraoperative bleeding, which was managed with hemostatic forceps. Eight patients had postoperative esophageal strictures in relation with circumferential extension and the longitudinal length (P<0.05).

CONCLUSIONESTD is a safe and effective alternative for large esophageal superficial neoplasms with a shortened operative time, a higher dissection speed and a higher radical curative rate in comparison with ESD, but postoperative esophageal strictures should be closely monitored especially for lesions more than 3/4 of the circumferential extension or exceeding 50 mm.

Objective To assess the diagnostic accuracy of preoperative endoscopic ultrasonography (EUS) for tumor size and invasion of non-ampullary duodenal neuroendocrine tumors (NA-DETs) and to compare the efficacy and safety of endoscopic submucosal dissection ( ESD ) and modified ESD for the treatment of NA-DETs. Methods Data of 22 patients with 22 NAD-NETs confirmed by histopathological examinations from January 2007 to January 2018 were retrospectively analyzed. ESD was performed on 13 tumors, and modified ESD was performed on 9 tumors. R0 resection rate, procedure time and incidence of procedure-related complications in the ESD group and the modified ESD group were compared. The postoperative pathological results were used as the gold standard to assess the accuracy of preoperative EUS in diagnosing tumor size and invasion of NA-DETs. Results The mean size of NA-DETs was 6. 9 ± 1. 5 mm. The accuracy in assessing the invasion depth by EUS was 95. 5％ ( 21/22 ) compared with histological results. R0 resection was achieved in 13/13 ( 100. 0％) of the ESD group and in 7/9 ( 77. 8％) of the modified ESD group (P=1. 000). The procedure time was significantly shorter in the modified ESD group than that in the ESD group ( 16. 0 ± 2. 2 min VS 29. 8 ± 4. 9 min, P<0. 001 ) . Intraoperative perforation occurred in one patient and delayed perforation occurred in one patient in the ESD group. Delayed bleeding occurred in one patient in the modified ESD group. Follow-up data were available in all cases with a mean period of 30. 0±24. 8 months. No cases of local recurrence or distant metastasis were detected in the follow-up period. Conclusion EUS can accurately assess the size and depth of NAD-NETs. Modified ESD can provide comparable clinical outcomes to ESD for NAD-NETs ≤10 mm in diameter that are confined to the submucosa.

Objective:To compare the efficacy and safety of endoscopic mucosal resection (EMR), EMR with pre-cutting (EMR-P), endoscopic submucosal dissection (ESD) and ESD with snare (ESD-S) for the treatment of colorectal laterally spreading tumors (LSTs).Methods:Between January 2016 and March 2018, a total of 146 patients with 146 colorectal LSTs undergone endoscopic resection at the first medical center of PLA General Hospital. Data of demographics, treatment information, pathology and follow-up results were retrospectively analyzed.Results:Among the 146 patients, EMR, EMR-P, ESD, and ESD-S were performed in 23, 29, 50 and 44 tumors, respectively. Median tumor diameter was 2.5 cm (ranged 1.2-10.0 cm). The en bloc resection rate of EMR, EMR-P, ESD and ESD-S were 73.9% (17/23), 72.4% (21/29), 96.0% (48/50), and 65.9% (29/44), respectively, with statistical difference ( P<0.001). And the R0 resection rate were 65.2% (15/23), 69.0% (20/29), 94.0% (47/50), and 63.6% (28/44), respectively, with statistical difference ( P=0.002). The en bloc resection rate and R0 resection rate of the ESD group were significantly higher than those of the other three groups (all P<0.05). The difference was not statistically significant in terms of perforation rate [0, 0, 6.0% (3/50), and 9.1% (4/44), respectively, P=0.269] and delayed hemorrhage rate [4.3% (1/23), 0, 2.0% (1/50), and 2.3% (1/44), respectively, P=0.768] among the four groups. Follow-up endoscopy was performed in 117 cases (80.1%) with a median period of 10.0 months (ranged 3.0-26.0 months), and local recurrence was identified in 7 (6.0%) cases. Conclusion:ESD could be the optimal method for the resection of colorectal LSTs, while LSTs smaller than 20 mm can be resected by EMR. EMR-P and ESD-S as modified methods have their respective advantages for the treatment of LSTs.

Objective:To explore the therapeutic effect of peroral endoscopic myotomy (POEM) for primary achalasia (AC) in patients aged over 60 years.Methods:Data of 146 patients aged ≥60 years (the elderly group) and 146 patients aged 18-59 years (the adult group) who received POEM from November 2010 to September 2019 at the Digestive Endoscopy Center of PLA General Hospital were retrospectively analyzed. Baseline data, surgery data, surgery-related complications and surgery-related efficacy were compared.Results:There was no significant difference in gender, Ling classification, HRM classification or previous treatment between the two groups ( P>0.05). All 292 patients successfully underwent POEM surgery. The clinical success (Eckardt score ≤3) rates in the elderly group and the adult group were 96.33% (105/109) and 96.77% (90/93), respectively with no significant difference between the two groups ( χ2=0.030， P>0.05). There was no significant difference in the length of myotomy between the two groups (7.09±2.49 cm VS 7.12±2.24 cm， t=0.472， P>0.05). Complications occurred in 26 cases (17.81%) in the elderly group and 21 cases (14.38%) in the adult group with no significant difference between the two groups ( χ2=0.634， P>0.05). There was no significant difference in the postoperative hospital stay (12.61±9.69 days VS 11.00±4.43 days, t=1.825, P>0.05) or the incidence of gastroesophageal reflux [43.33% (13/30) VS 51.52% (17/33), χ2=0.422, P>0.05] between the elderly group and the adult group. Conclusion:The efficacy of POEM for AC patients over 60 years old is equivalent to that of adult patients, and the incidence of complications is similar. POEM is safe and effective for AC patients over 60 years old.
