[Double balloon endoscopy in diagnosis of patients with obscure gastrointestinal bleeding].

OBJECTIVE: To assess the diagnostic value of double balloon endoscopy (DBE) for obscure gastrointestinal bleeding (OGIB) METHODS: The data of 103 OGIB patients who underwent DBE from January 2007 to September 2010 in the First Affiliated Hospital, Zhejiang University School of Medicine were retrospectively analyzed. RESULTS: DBE was successfully performed in all 103 patients without complications. Of 103 patients, 66(64.1 %) had positive DBE findings and 28 had surgery procedures(27.2 %). Ninety-four patients finally acquired positive diagnosis, including small intestine tumor(31.1 %), angiodysplasia(22.3 %), exulceratio simplex(9.7 %), Crohn's disease(6.8 %), diverticulum(4.9 %), abdominal purpure(4.9 %), etc. Lesions occurred more frequently in proximal small intestine than in distal small intestine (56.3 % Compared with 30.1 %, P<0.001). CONCLUSION: DBE is a safe, effective and reliable procedure for the diagnosis of OGIB.

Unexplained septic shock after colonoscopy with polyethylene glycol preparation in a young adult: A case report.

BACKGROUND: Colonoscopy has become a routine physical examination as people's health awareness has increased. Polyethylene glycol (PEG) is greatly used in bowel preparation before colonoscopy due to its price and safety advantages. Septic shock after colonoscopy with PEG preparation is extremely rare, with only very few cases in critically ill patients. Herein, we describe a case of septic shock in a healthy young adult immediately following colonoscopy with PEG preparation. CASE SUMMARY: A 33-year-old young adult presented to our hospital for colonoscopy with PEG bowel preparation due to recurrent diarrhea for 7 years. The male's previous physical examination showed no abnormal indicators, and colonoscopy results were normal; however, he exhibited septic shock and markedly elevated white blood cell, C-reactive protein, and procalcitonin levels on the second day after colonoscopy. Immediate resuscitation and intensive care with appropriate antibiotics improved his condition. However, the blood and stool cultures did not detect the pathogen. CONCLUSION: Septic shock after colonoscopy is rare, especially in young adults. The authors considered the possibility of opportunistic infections after PEG bowel preparation, and clinicians should monitor patients for the possibility of such complications.

[Diagnostic values of double-balloon enteroscopy and abdominal computed tomography in small bowel disease].

OBJECTIVE: To evaluate the diagnostic values of double-balloon enteroscopy (DBE) and abdominal computed tomography (CT) in small bowel disease. METHODS: Seventy eight DBE procedures were carried out in 70 patients, 40 males and 30 females; aged 47.7 (16 - 83) with suspected small bowel disease, all of whom received gastroscopy, colonoscopy, and abdominal CT examination at the same time. The diagnostic value of DBE was compared with that of CT. RESULTS: Seventeen kinds of small bowel lesions were detected, mainly including Crohn's disease, adenocarcinoma, gastrointestinal stroma tumor, vascular deformity, lymphoma, diverticulum, and polyp. There were no complications and all procedures were tolerated well. The mean duration of procedure was 110 min (30 - 240 min). Nineteen patients received surgical intervention. The diagnostic yield rate of DBE was 57.1% (40/70), significantly higher than that of CT (31.4%, 22/70, P < 0.01). The positive diagnosis rate of DBE combined with CT was 62.9% (44/70), not significant different from that of the DBE alone (P > 0.05). CONCLUSION: DBE shows a significantly higher diagnostic yield than CT in patients with suspected small bowel disease, and thus should be selected for the initial diagnosis. DBE Combined with CT did not increase the diagnostic yield. However, CT not only provides direction of intubation for DBE, but also clearly depicts the small bowel wall and extraenteric alterations. DBE and CT compliment each other in examining the patients with suspected small bowel disease.

[The study of Rougan Jiedu formula anti-liver cancer in vivtro].

OBJECTIVE: To observe the effects of the anti-liver cancer pharmacodynamic action of the Rougan Jiedu formula through the experiments of inhibiting cell proliferation of the tumour cell in vitro. METHODS: The pharmaceutic serum of Rougan Jiedu formula was prepared and the influence of the pharmaceutic serum of Rougan Jiedu formula to the cell proliferation of hepatoma carcinoma cell HepG2, SMMC-7721 was observed. RESULTS: Rougan Jiedu formula blood-serum could remarkably inhibit the proliferation of the cell line of HepG2, SMMC-7721, the maximum inhibition ratio to the HepG2 was 69.73%, the maximum inhibition ratio to the SMMC-7721 was 69.73%. Compared to the blank group and PBS group, the difference was significant (P < 0.01); the effects of high dose, compared to the 5-FU group, the difference had no significance (P > 0.05). The inhibition ratio of Chinese medicine groups followed the increase of the doses. CONCLUSION: The Rougan Jiedu formula has good effects on inhibiting the proliferation of the tumour cell in vitro.

Double-balloon enteroscopy in small bowel tumors: a Chinese single-center study.

AIM: To analyze the clinical characteristics of small bowel tumors detected by double-balloon enteroscopy (DBE) and to evaluate the diagnostic value of DBE in tumors. METHODS: Four hundred and forty consecutive DBE examinations were performed in 400 patients (250 males and 150 females, mean age 46.9 ± 16.3 years, range 14-86 years) between January 2007 and April 2012. Of these, 252 patients underwent the antegrade approach, and 188 patients underwent the retrograde approach. All the patients enrolled in our study were suspected of having small bowel diseases with a negative etiological diagnosis following other routine examinations, such as upper and lower gastrointestinal endoscopy and radiography tests. Data on tumors, such as clinical information, endoscopic findings and operation results, were retrospectively collected. RESULTS: Small bowel tumors were diagnosed in 78 patients, of whom 67 were diagnosed using DBE, resulting in a diagnostic yield of 16.8% (67/400); the other 11 patients had negative DBE findings and were diagnosed through surgery or capsule endoscopy. Adenocarcinoma (29.5%, 23/78), gastrointestinal stromal tumor (24.4%, 19/78) and lymphoma (15.4%, 12/78) were the most common tumors. Among the 78 tumors, 60.3% (47/78) were located in the jejunum, and the overall number of malignant tumors was 74.4% (58/78). DBE examinations were frequently performed in patients with obscure gastrointestinal bleeding (47.4%) and abdominal pain (24.4%). The positive detection rate for DBE in the 78 patients with small bowel tumors was 85.9% (67/78), which was higher than that of a computed tomography scan (72.9%, 51/70). Based on the operation results, the accuracy rates of DBE for locating small bowel neoplasms, such as adenocarcinoma, gastrointestinal stromal tumor and lymphoma, were 94.4%, 100% and 100%, respectively. The positive biopsy rates for adenocarcinoma and lymphoma were 71.4% and 60%, respectively. CONCLUSION: DBE is a useful diagnostic tool with high clinical practice value and should be considered the gold standard for the investigation of small bowel tumors.

Double-balloon enteroscopy for obscure gastrointestinal bleeding: a single center experience in China.

AIM: To evaluate the diagnostic value of double-balloon enteroscopy (DBE) for obscure gastrointestinal bleeding (OGIB). METHODS: The data about 75 OGIB patients who underwent DBE in January 2007-June 2009 in our hospital were retrospectively analyzed. RESULTS: DBE was successfully performed in all 75 patients without complication. Of the 75 patients, 44 (58.7%) had positive DBE findings, 22 had negative DBE findings but had potential bleeding at surgery and capsule endoscopy, etc. These 66 patients were finally diagnosed as OGIB which was most commonly caused by small bowel tumor (28.0%), angiodysplasia (18.7%) and Crohn's disease (10.7%). Lesions occurred more frequently in proximal small bowel than in distal small bowel (49.3% vs 33.3%, P = 0.047). CONCLUSION: DBE is a safe, effective and accurate procedure for the diagnosis of OGIB.
