RESUMO
Objective To investigate the feasibility and application value of total enteroscopy with double balloon enteroscopy(DBE)for diagnosis and treatment of patients with obscure gastrointestinal bleeding(OGIB). Methods The clinical and endoscopic data of patients underwent DBE for OGIB in the Department of Gastroenterology,Remin Hospital of Wuhan University from January 2010 to December 2015 were retrospectively analyzed. Results Total enteroscopy was indicated in 36.3%(136/375)of patients. The success rate was 86.0%(117/136)and complication rate was 1.5%(2/136). Negative findings,non-small bowel lesions and small bowel lesions were detected in 44.4%(52/117), 6.8%(8/117), and 48.7%(57/117)of patients with total enteroscopy. Re-bleeding occurred in 8.9%(4/45)of patients with negative total enteroscopy,while 1 small bowel mesenchymoma and 1 gastric fundus Dieulafoy′s lesion were revealed subsequently. Re-bleeding occurred in 33.3%(5/15)of patients with incomplete enteroscopy,and 1 small bowel polyp and 1 small bowel angiectasis were revealed subsequently. Conclusion DBE can complete total enteroscopy within one day and provide important clinical information of OGIB. Non-small bowel lesions,small bowel lesion missed by DBE and potential bleeding lesions in small bowel beyond the reach of DBE should be considered in patients with negative enteroscopy.
RESUMO
Objective To assess the value of double balloon enteroscopy (DBE) in etiological diagnosis of small bowel ulcer.Methods The clinical and endoscopic data of patients undergoing DBE at the Department of Gastroenterology, Renmin Hospital of Wuhan University from January 2010 to January 2016 were reviewed.For patients with small bowel ulcer revealed by DBE, the etiologic diagnosis was retrospectively analyzed.Results One hundred and three patients with small bowel ulcer were included in the analysis.The initial diagnosis based on morphology of ulcer was Crohn's disease (58.3%, 60/103), intestinal tuberculosis (18.4%,19/103), etiology unknown (24.3%, 25/103).The final diagnosis comprehensively based on pathology, clinical data and disease outcome was Crohn's disease (44.7%,46/103), intestinal tuberculosis (18.4%,19/103), lymphoma (3.8%,4/103), eosinophils enteritis (1.9%,2/103), non-steroidal anti-inflammatory drug enteritis (1.9%,2/103), adenocarcinoma (1.0%,1/103), stroma tumor (1.0%,1/103),ischemic enteritis (1.0%,1/103), vascular malformation (1.0%,1/103), Henoch-Schonlein purpura (1.0%,1/103), etiology unknown (24.3,25/103).The accurate diagnosis rate and misdiagnosis rate for Crohn's disease by DBE were 73.3%(44/60)and 10.0%(6/60).The accurate diagnosis rate and misdiagnosis rate for intestinal tuberculosis by DBE were 14/18 and 2/18.Conclusion There are diversity and complexity in etiologic diagnosis of small bowel ulcer.The diagnosis should be based on the comprehensive analysis of morphology of ulcer, endoscopic and surgical pathology and clinical data.Follow up of small bowel ulcer by DBE may provide important information for etiologic diagnosis.
RESUMO
were no significant differences in the detection rate of recto-sigmoid colon,mid colon,right colon and total detection of polyps among the 3 groups (P >0.05).Conclusion 4-L split-dose PEG is better than the oth-er 2 regimens in the colon cleansing quality,so it can better reach the intestinal cleaning standards before enteroscopy,which is a more suitable regimen for bowel preparation.
RESUMO
Objective To investigate the safety,diagnostic value and clinical impact of double balloon enteroscope (DBE) in elderly patients (aged ≥75 years).Methods Clinical data and DBE findings of elderly patients in the Department of Gastroenterology in Remin Hospital of Wuhan University from January 2010 to January 2013 were retrospectively analyzed and compared with those of younger patients.Results The diagnostic rate,complication rate and clinical impact rate were 69.0％ (29/42),0％ (0/42) and 76.2％ (32/42) in elderly patients.There were no statistically significant differences on those parameters between elderly patients and younger patients (all P＞0.05).For elderly patients,the leading causes of obscure gastrointestinal bleeding (OGIB) were tumor (30.0 ％,9/30) and ulcer (16.7 ％,5/30),while angiectasis (6.7 ％,2/30) was uncommon.Conclusions DBE is an effective and safe method for diagnosis of small bowel disease in elderly patients.Tumor is the most common cause of OGIB,while angiectasis was uncommon.
RESUMO
Objective To analyze the clinical features of patients with negative double balloon enteroscopy(DBE)findings.Methods A total of 115 patients with suspected small intestinal diseases underwent DBE examination from gastroenterology department of Wuhan University People's hospital on December 2005 to July 2009.The negative and positive cases were 32 and 83 respectively,then compared clinical data of negative group with that of positive group.Results 83 cases with small intestinal diseases were detected from 115 patients by DBE examination,and the daignosis rate was 72.2%(83/115).2 patients occurred acute pancreatitis and 1 occurred hyperamylasemia.The level of initial hemoglobin of negative group was higher than that of positive group(107.938?26.015 vs 93.518?32.367,P=0.016).meanwhile,there were significant difference in clinical symptoms(unexplained alimentary tract hemorrhage,obscure partial bowel obstruction,abdominal pain and diarrhea)between two groups(P=0.035).Moreover,the positive detection rate of unexplained alimentary tract hemorrhage(81.8%)was obviously higher than that of abdominal pain(57.7%)or diarrhea(40%).Conclusion DBE examination is an effective method in the diagnosis of small bowel diseases at present,however,patients with higher level of initial hemoglobin or the main symptoms as abdominal pain or diarrhea should be prudent to choose.
