ABSTRACT
Objective To evaluate the efficiency and safety of full-spectrum endoscopy for detection of major duodenal papilla. Methods Patients underwent painless gastroscopy in Chinese PLA General Hospital from March 2017 to December 2017 were enrolled and randomly divided into two groups according to random number method. The group A underwent conventional gastroscopy, and the group B underwent full-spectrum endoscopy. The detection rate of major duodenal papilla was calculated and compared between the two groups. Results A total of 100 patients were recruited in the study, including 51 in the group A and 49 in the group B. The whole detection rate of major duodenal papilla of the group B was higher than that of the group A [79. 59％ (39/49) VS 41. 18％ (21/51), χ2 =15. 366, P=0. 000]. There was no statistical difference on the whole plus partial detection rate of major duodenal papilla between the two groups [100. 00％ (49/49) VS 92. 16％ (47/51), χ2=2. 221, P=0. 136]. All patients completed endoscopy examination succesfully without bleeding, peforation or death. Conclusion With the broad view-field, full-spectrum endoscopy is useful to improve the efficiency and safety in detection of major duodenal papilla.
ABSTRACT
Objective To evaluate the diagnostic efficiency of full-spectrum endoscopy(FUSE) versus conventional colonoscopy for colonic polyps and adenoma. Methods Patients who underwent colonoscopy were randomly allotted into two groups according to randomization and self-control criteria. Patients in group A underwent conventional endoscopy firstly and then to FUSE. Patients in group B were opposite performed the examinations. The polyps and adenomatous polyps were resected or biopsied for pathological examination. Miss rate of colonic polyps as well as adenomatous polyps was calculated. Results A total of 100 patients were recruited for the study,including 45 in group A and 55 in group B. FUSE was significantly superior compared to conventional endoscopy with lower miss rate of polyps(6.52% VS 34.04%,χ2=17.685,P=0.000)as well as adenomatous polyps(5.00% VS 34.38%, χ2=11.774, P=0.001). For the first endoscopic examination,the adenomatous polyps which were found out by FUSE were more than that of ordinary colonoscopy in the right colon(χ2=5.153,P=0.023). The size of adenoma found by ordinary colonoscopy and FUSE was no statistically different whether in the first(t=0.334,P=0.739)or second(t=1.297,P=0.219)endoscopic examinations. Conclusion FUSE is useful to improve the quality of endoscopic examination because of its broad view-field.
ABSTRACT
Objective To assess the clinical value and safety of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) for duodenal lesions.Methods The data of 12 patients with duodenal space-occupying lesions underwent EMR or ESD from January 2010 to December 2015 in Chinese PLA General Hospital were retrospectively analysed.Results All patients received operation, including 9 male and 3 female with mean age of 50.0 years(33.0-62.0 years).There were 8 lesions in duodenal bulb and 4 in descending part.The mean diameter of the lesions was 1.2 cm (0.5-3.0 cm).Three lesions were originated from mucosa, of which 2 were high-grade intraepithelial neoplasia and 1 was villous/tubular adenoma.Nine lesions were located in submucosa, including 3 cases of neuroendocrine neoplasm, 1 case of stromal tumor, 1 liomyoma case, 1 lipoma case, 1 case of Brunner glands adenoma, 1 case of ectopic pancreas, and 1 inflammatory lesion.One patient had perforation with rate of 8.3%(1/12) and was recovered after conserved treatment.The bleeding was very little during operation.No infection or stenosis happened.The mean hospitalized time was 6.0 days (1.0-12.0 days) after operation.No recurrence was found during 23.8 months(3.0-73.0 months) of follow-up.Conclusion EMR and ESD are effective and safe for treatment of duodenal space-occupying lesions.
ABSTRACT
Objective To explore the effectiveness and safety of limited endoscopic sphincterotomy plus endoscopic papillary balloon dilation (ESBD)for patients with large common duct stones and periampul-lary diverticula (PAD).Methods Data of 40 patients with large common duct stones (diameter ≥10 mm) and PAD who underwent ESBD were retrospectively reviewed.The clinical feature,operation method,suc-cess rates of stone removal and early complications rates during hospitalization were evaluated according to PAD subtypes.Results The stone removal rate in first session was 90.0%(36 /40,with a median time of 29 minutes per procedure.Three patients underwent a second procedure to remove residual stones.The over-all stone removal rate was 97.5% (39 /40).The early complications rate was 15%(6 /40),including mild pancreatitis in two cases(5%),hyperamylasemia in two (5%),postoperative late bleeding in two (5%), which were cured with conservative treatment.No perforation,massive hemorrhage or death occurred.No significant differences in success stone removal rate and early complication rate were found between PAD sub-types.Conclusion ESBD is an effective and safe procedure for removing choledocholithiasis in patients with PAD,regardless of PAD subtypes.
ABSTRACT
Objective To investigate the clinical features and prognosis of rectal neuroendocrine neoplasms (NENs) in different pathological grades.Methods The clinical data of 183 patients with rectal NENs who were admitted to the PLA General Hospital from January 2001 to April 2012 were retrospectively analyzed.All the clinical and pathological data of the patients who received endoscopy and (or) surgical resection were retrieved from the work station and the database of the endoscopic center.Based on the 2010 WHO pathology classification of digestive tumors,the pathological data were ranked according to the mitotic count.The prognosis of the patients was learned by re-examination or phone call.The follow-up ended till July 2014 or at the death of patients.Data were analyzed using the chi-square test.Results A total of 183 patients were enrolled in this study including 120 males and 63 females.The median age of the patients was 48 years (range,14-83 years).Seventy-four patients had the symptom of hemafecia,9 patients had abdominal pain and change in bowel habit,and 70 patients were diagnosed by body examination.Other symptoms included increased level of tumor markers and abdominal distension.Carcinoid syndrome was not detected in all the patients.Fourteen patients were complicated with polyp of intestine,5 with tubular adenoma,3 with colorectal adenocarcinoma and 1 with small cell lung cancer.The diameters of the tumor under 1 cm were detected in 162 patients,the diameters of the tumors ranged between 1 cm and 2 cm in 14 patients,and the diameters of the tumors above 2 cm in 7 patients.The mean distance between the tumor and the anus was (5-± 3)cm.Of the 183 patients,130 received endoscopic treatment,43 received surgical treatment and 10 received clamping because the tumor was misdiagnosed as polyps.There were 158 patients in grade1 (154 in stage Ⅰ,1 in stage Ⅱ,1 in stage Ⅲ and 2 in stage Ⅳ),21 in grade2 (13 in stage Ⅰ,3in stage Ⅱ,3 in stage Ⅲ and 2 in stage Ⅳ),4 in grade 3 (1 in stage Ⅰ,1 in stage Ⅲ and 2 in stage Ⅳ).Six patients had liver metastasis and 9 had lymph node metastasis.Fourteen patients died (4 in grade 1,6 in grade 2 and 4 in grade 3).The 5-year survival rate of patients was 92.35％ (169/183).There were significant differences in the gender,tumor diameter,tumor staging,lymph node metastasis distal metastasis and 5-year survival rate among patients with rectal NENs in different pathological grades (x2=60.949,71.587,32.135,55.486,56.512,P ＜ 0.05).Conclusions Rectal NENs lacks the specific clinical manifestation and is more likely to happen in males,and it often locates at the middle-lower rectum.Most of the rectal NENs belongs to stage Ⅰ and grade 1 and is less than 1 cm in size.The prognosis of patients with rectal NENs in different pathological grades is different.The 2010 WHO pathology classification of digestive tumors is useful to asses the prognosis of rectal NENs.Different grades of rectal NENs could be taken into account when designing the treatment plan.
ABSTRACT
Objective To study the related prognostic factors influencing rectal neuroendocrine tumor prognosis.Methods We retrospectively reviewed tumor clinical and pathology material of 183 cases with rectal neuroendocrine in our hospital during recent 10 years and reclassified them according to the 2010 WHO pathology classification.Single factor and multivariate analysis were performed to find related prognostic factors.Results Single factor analysis showed that tumor size (＜ 1 cm,1-2 cm,＞2 cm,98.77％ vs 78.57％ vs 28.57％,x2 =71.4793,P =0.0001),pathological grading (G1,G2,G3,98.73％ vs.76.19％ vs 25.00％,x2 =56.5121,P =0.0001) and the stage (stage Ⅰ,Ⅱ,Ⅲ,Ⅳ period,99.40％ vs 50.00％ vs 60.00％ vs 16.67％,x2 =105.0383,P =0.0001) among the three variables survival difference was statistically significant.Multivariate analysis (Cox regression) indicated that the tumor stage were independent factors affecting the prognosis,regression coefficient was 1.277 (B),Wald value of 28.145,Exp (B) a value of 3.586,95％ CI:2.237-5.747.Conclusion Tumor staging is an independent risk factor of survival,without considering other factors,different tumor size and pathologic grade also have different prognosis.Clinicians in making treatment plan should fully consider the above factors before choosing the appropriate follow-up plan.
ABSTRACT
Objective To compare the cost-effectiveness between endoscopic submucosal dissection (ESD) procedure and traditional surgery for the treatment of early gastrointestinal cancer or precancerous lesions.Methods A total of 866 early GI cancer/precancerous patients who had been admitted to Chinese PLA General hospital and Qilu hospital were included in this study.The medical records of all 866 patients were reviewed.Patients were divided into ESD group and traditional surgery group.Parameters of each patient,such as time of hospitalization,total treatment cost and incidence of complications,were documented and later compared in detail.Results A total of 607 patients were included in the ESD group and 259 in the traditional surgery group.There was no statistical difference in complete resection rate between the two groups (93.1％ vs 93.0％,P ＞ 0.05).The ESD group showed a shorter mean hospitalization time (d)(13.01 vs 18.88,P ＜ 0.05) and lower treatment cost (RMB) than the traditional surgery group (22932.17 vs 57993.88,P ＜ 0.05).The incidence of hemorrhage and perforation for each group were 3.63％ and 3.10％ respectively,which were not significantly different (1.98％ vs 3.01％,P ＞ 0.05; 2.80％ vs 1.16％,P ＞ 0.05).Conclusion ESD and surgery are both effective for early gastrointestinal cancer/precancerous lesions therapy,but ESD procedure is superior to surgery in terms of hospitalization time and expediture.
ABSTRACT
ObjectiveTo investigate the procedure,effect and complication of endoscopic submucosal dissection (ESD) in the management of early gastrointestinal tumors and precancerous lesions.MethodsESD was performed in 28 patients with 29 lesions of early cancer and precancerous lesions in esophagus,stomach,colon and rectum.First we made marks around the lesion 3-5 mm away from the margin with a needle knife or APC,then injected solution into submucosa to elevate the lesion,and cut the mucosa and submucusa along the margin with a needle knife or IT knife.The submucosa was carefully dissected until the lesions were completely removed with IT knife.Bleeding was stopped with thermocoagulation forceps,argon plasma coagulation or clip.The samples were collected for pathological examination.All patients were followed up with endoscopy as scheduled.ResultsOf the 29 lesinas,22 were en bloc resected,6 were piecemeal resccted,and 1 was partial removed.The resection rate of antral lesion was 100% (12/12),and that of lesions between angulus and cardia was 5/7,that of esophageal lesions was 3/5 and that of colorectal ncoplasmns was 2/5.Delayed bleeding occured in 1 patient.The mean operation time for the antral lesions was 48 minutes.Twenty patients were followed up for 1 to 12 months.No residue or recurrence of the lesions was found.ConclusionThe major advantage of ESD is that the resection area can be determined by the size and shape of the lesion,and resection can be achieved en bloc even in a large neoplasm.

ABSTRACT
Objective To evaluate the efficacy and safety of the covered retrievable metal stent in the treatment of refractory benign esophageal stricture. Methods Six patients with refractory benign esophageal stricture who failed in endoscopic dilation were selected. There were 3 cases of stricture after caustic chemical ingestion, 2 cases of anastomotic stricture after surgery, and 1 case of re-stricture after metal stenting. The shape and diameter of the covered stent were individually designed. Stent was placed across the esophageal stricture. Symptoms after stenting, mucosal hyperplasia at the ends of stent and symptoms after retrieval of stent were followed up. Results Stent placement was performed successfully in all patients. After the stent placement, dysphagia was resolved, and all patients could consume soft food. Three to six months after stenting, all the stents were removed successfully by endoscopy. No mucosal hyperplasia and re-stricture occurred. In 4 cases, after stent had been removed, followed up for 2 to 12 months, symptoms of dysphagia were resolved persistently, and no further treatment was necessary. In the other 2 cases, the stent migrated, and dysphagia recurred within 1 month after removal of the stent. Besides one case of retrostemal pain after stenting, no other complication was noted. Conclusion Individually designed covered retrievable metal stent is a safe and effective way to treat refractory benign esophageal stricture.
