    To study the immediate clinical, echocardiographic and hemodynamic results of 200 patients who underwent percutaneous mitral balloon valvotomy (PMV) with double balloon technique. Two hundred patients were submitted to PVM for treatment of congestive heart failure secondary to severe mitral stenosis, between August 1987 to July 1991. Their mean age was 35.2 years, and 86.5% were female patients: 81% of them was in functional class, New York Heart Association (NYHA) III or IV; 4% was in atrial fibrilation and 4% had previous surgical commissurotomy. PMV was successfully performed in 89% of the patients. The mitral valve area, by pressure half time method, increased from 0.91 +/- 0.27 to 2.10 +/- 0.47 cm2, p atrial septum could not be performed. Mitral regurgitation (MR) immediately after PMV appeared 1+ or more grade in 50 patients, increased in 8 patients and remained unchanged in 11 patients. Ten patients needed mitral valve replacement in the first 48h after PMV, for treatment of severe MR. PMV produces excellent immediate results and can be considered an alternative to surgery for the relief of mitral stenosis.

    Full Text Available Double balloon enteroscopy (DBE was introduced 15 years ago. The complications of diagnostic DBE are rare, acute pancreatitis is most redoubtable one (incidence about 0.3%. Hyperamylasemia after DBE seems to be a rather common condition respectively. The most probable cause seems to be a mechanical straining of the pancreas. We tried to identify patients in a higher risk of acute pancreatitis after DBE. We investigated several laboratory markers before and after DBE (serum cathepsin B, lactoferrin, E-selectin, SPINK 1, procalcitonin, S100 proteins, alfa-1-antitrypsin, hs-CRP, malondialdehyde, serum and urine amylase and serum lipase. Serum amylase and lipase rose significantly with the maximum 4 hours after DBE. Serum cathepsin and procalcitonin decreased significantly 4 hours after DBE compared to healthy controls and patients values before DBE. Either serum amylase or lipase 4 hours after DBE did not correlate with any markers before DBE. There was a trend for an association between the number of push-and-pull cycles and procalcitonin and urine amylase 4 hours after DBE; between procalcitonin and alfa-1-antitrypsin, cathepsin and hs-CRP; and between E-selectin and malondialdehyde 4 hours after DBE. We found no laboratory markers determinative in advance those patients in a higher risk of acute pancreatitis after DBE.

    AIM: To evaluate the clinical outcome of enteroscopy, using the double-balloon method, focusing on the involvement of neoplasms in strictures of the small intestine. METHODS: Enteroscopy, using the double-balloon method, was performed between December 1999 and December 2002 at Jichi Medical School Hospital, Japan and strictures of the small intestine were found in 17 out of 62 patients. These 17 consecutive patients were subjected to analysis. RESULTS: The double-balloon enteroscopy contributed to the diagnosis of small intestinal neoplasms found in 3 out of 17 patients by direct observation of the strictures as well as biopsy sampling. Surgical procedures were chosen for these three patients, while balloon dilation was chosen for the strictures in four patients diagnosed with inflammation without involvement of neoplasm. CONCLUSION: Double-balloon enteroscopy is a useful method for the diagnosis and treatment of strictures in the small bowel. PMID:15742422

    A 31-year-old man has visited our hospital, complaining diarrhea and leg edema. Blood test showed hypoalbuminea, but we couldn't find the reason by several examinations. Therefore, we performed double balloon enteroscopy, and intestinal lymphangiectasia was diagnosed histologically by biopsy. It's useful and effective to perform double balloon enteroscopy and histological examination for the unknown origin case of protein loosing enteropathy.

    Conclusion: There was no significant additional benefit of using a double-balloon catheter in midtrimester termination of pregnancy, although the technique was considered simple and generally well-tolerated. Placing a transcervical double-balloon catheter could be the primary method, or one of the alternative medical methods if the patient and/or obstetrician prefers no operation.

    Microscopic polyangiitis is characterized by pauci-immune, necrotizing small-vessel vasculitis and an anti-neutrophil cytoplasmic antibody-associated vasculitis. Although gastrointestinal involvement in microscopic polyangiitis is not rare, endoscopic observation of it is extremely rare. To the best of our knowledge, this is the first case report of small intestinal involvement in microscopic polyangiitis detected and followed up by double-balloon endoscopy. A 70-year-old Japanese woman was transferred to our hospital for close examination of suspected small intestinal lymphoma. Retrograde double-balloon endoscopy revealed various forms of ulcers with redness and edema in the ileum. Histological findings suggested ischemic changes. Because mononeuritis multiplex and a fever spike appeared later, vasculitis was suspected. The perinuclear anti-neutrophil cytoplasmic antibody titer was elevated. Nerve biopsy results suggested vasculitis. From these findings, microscopic polyangiitis was diagnosed. It was suggested that microscopic polyangiitis caused the intestinal involvement. Intravenous pulse cyclophosphamide and oral predonisolone were started. After treatment, perinuclear anti-neutrophil cytoplasmic antibodies decreased to the normal range. Retrograde double-balloon endoscopy after treatment showed ulcer scars and no ulcer. The cause of gastrointestinal involvement in microscopic polyangiitis is ischemia due to vasculitis. It is difficult to diagnose small-vessel vasculitis by endoscopic biopsy. Although histological evidence of microscopic polyangiitis is important, the treatment should not be delayed by repeating the biopsy, because such delay can result in adverse sequela.This case report shows that microscopic polyangiitis should be considered as a differential diagnosis when small intestinal changes like those in the present case are observed by endoscopy.

    A retrospective and descriptive study was conducted to assess the accuracy, effectiveness and extent of the double balloon enteroscope screening in the diagnosis of small intestine diseases in children. Eight patients were studied by means of physical examination and negative complementary ones of small intestine disease, seen between November, 2008 and October, 2009. In three patients there was the clinical and radiological suspicion of Crohn's disease; in other three the suspicion of small intestine tumor and remainder were seen due to hidden bleeding of intestinal origin

  9. The value of double balloon enteroscopy in diagnosing blue rubber bleb naevus syndrome: a case report.

    2010-01-01

    Blue rubber bleb naevus syndrome is a rare vascular disorder associated with multiple gastrointestinal haemangiomas that have the potential for life-threatening haemorrhage. These may be difficult to diagnose, and have classically been described using computed tomographic studies and\\/or mesenteric angiography. Resected surgical specimens of these lesions, especially in the small bowel, have often been extensive and poorly localized. The recent advent and progressive development of double balloon enteroscopy has allowed the direct visualization and marking of these enteric lesions and serves as a valuable adjunct not only in diagnosis but also planning prior to surgery to allow accurate estimate of the extent of resection.

    This randomised controlled study compared the efficacy of double-balloon catheter versus vaginal prostaglandin E2 (dinoprostone) for induction of labour. In total, 825 pregnant women with cephalic presentation and an unfavourable cervix undergoing induction for conventional indications were...... randomised to double-balloon or vaginal dinoprostone (3 mg) groups. There was a significantly higher failure rate for labour induction in the balloon group (relative risk: 1.25, 95% confidence interval [CI]: 1.02-1.49). Median induction time was 27.3 h in the balloon group and 29.8 h in the dinoprostone...

    The double-balloon urethrography can be recommended as an efficient diagnostic method for examination of the urethra in the female patient. Because of its improved controllability, retrograde application of the contrast agent is superior to other techniques. Complications can be avoided by maintaining constant pressure during contrast agent application. The few commercially available double-balloon instruments suffer from a number of deficiencies which are the reason for this technique having met with low acceptance, thus being only rarely applied. In addition, application of the instrument is not easy. Nevertheless, this diagnostic technique would deserve much more frequent application. (orig.) [de

    Congenital H-type and recurrent tracheo-esophageal fistulas (TEF) are always difficult to diagnose. For a more accurate diagnosis we designed a new double balloon catheter, which is a modification of esophageal dilatation balloon. The catheter has two balloons to occlude the esophagus proximal and distal to the fistula. The fistula can be identified by passing of the contrast material to the tracheal tree, which was injected into the esophageal segment between the inflated balloons. To prove the efficiency of this catheter, a TEF was created surgically in a New Zealand rabbit. On the postoperative fourteenth day the catheter was tried and the fistula could be visualized easily by injecting the contrast material. We think this technique may be of use in the diagnosis of TEF in children. (orig.)

    2001-01-01

    Purpose: Further development of a previously described interventional method for isolated liver perfusion (ILP) with a new double-lumen balloon catheter, and evaluation of the side-effects of such isolation.Methods: In six pigs a double-balloon occlusion catheter was placed via the transjugular approach with its tip in the portal vein. One of the balloons was positioned in the inferior vena cava (IVC), cranial to the origin of the hepatic veins and the other balloon in the portal vein. By the transfemoral approach, a single-balloon occlusion catheter was placed in the IVC caudal to the origin of the hepatic veins. A third catheter was placed by the transfemoral route with the occlusion balloon in the proper hepatic artery. After inflation of all balloons 99 Tc m -labelled human serum albumin was recirculated through the liver. The isolation was evaluated by repeated measurement of radioactivity levels in peripheral blood. Laboratory tests of liver and pancreas function, and hemoglobin, were taken before, at the end of, and 3 days after the procedure. Blood gases were tested at the beginning and end of the procedure.Results: One pig died during the procedure due to technical failure and was excluded from the study. In the other pigs leakage from the isolated liver to the systemic circulation increased slowly, up to 9.7% (mean) during 30 min of recirculation of the perfusate through the liver. Laboratory tests were normal in all pigs except insignificant acidosis directly after the procedure and the slight elevation of s-ALAT after 3 days.Conclusions: Only minor leakage from the liver to the systemic circulation was noted during ILP performed with a new, double-balloon catheter. There were no serious side effects

    A case of multiple hepatocellular carcinomas with a severe intrahepatic arterioportal shunt that was successfully embolized with n-butyl-2-cyanoacrylate with coaxial double-balloon occlusion prior to transcatheter arterial chemoembolization is presented. A proximal balloon positioned at the proper hepatic artery was used for flow control, and a coaxial microballoon, positioned in the closest of three arterial feeding branches to the arterioportal shunt, was used to control the delivery of n-butyl-2-cyanoacrylate. This coaxial double-balloon technique can prevent proximal embolization and distal migration of n-butyl-2-cyanoacrylate and enable precise control of the distribution of n-butyl-2-cyanoacrylate. It could also be applicable to n-butyl-2-cyanoacrylate embolization for other than intrahepatic arterioportal shunt.

    Primary intestinal lymphangiectasia (PIL) is a rare disorder characterized by dilated intestinal lymphatics and the development of protein-losing enteropathy. Patients with PIL develop hypoalbuminemia, hypocalcemia, lymphopenia and hypogammaglobulinemia, and present with bilateral lower limb edema, fatigue, abdominal pain and diarrhea. Endoscopy reveals diffusely elongated, circumferential and polypoid mucosae covered with whitish enlarged villi, all of which indicate intestinal lymphangiectasia. Diagnosis is confirmed by characteristic tissue pathology, which includes dilated intestinal lymphatics with diffusely swollen mucosa and enlarged villi. The prevalence of PIL has increased since the introduction of capsule endoscopy. The etiology and prevalence of PIL remain unknown. Some studies have reported that several genes and regulatory molecules for lymphangiogenesis are related to PIL. We report the case of a patient with PIL involving the entire small bowel that was confirmed by capsule endoscopy and double-balloon enteroscopy-guided tissue pathology who carried a deletion on chromosome 4q25. The relationship between this deletion on chromosome 4 and PIL remains to be investigated. PMID:22110841

    Intestinal lymphangiectasia is a rare disease characterized by focal or diffuse dilated enteric lymphatics with impaired lymph drainage. It causes protein-losing enteropathy and may lead to gastrointestinal bleeding. Commonly, lymphangiectasia presents as whitish spots or specks. To our knowledge, small bowel bleeding resulting from polypoid intestinal lymphangiectasia has not been reported. Here, we report a rare case of active bleeding from the small bowel caused by polypoid lymphangiectasia with a review of the relevant literature. An 80-year-old woman was hospitalized for melena. Esophagogastroduodenoscopy could not identify the source of bleeding. Subsequent colonoscopy showed fresh bloody material gushing from the small bowel. An abdominal-pelvic contrast-enhanced computed tomography scan did not reveal any abnormal findings. Video capsule endoscopy showed evidence of active and recent bleeding in the ileum. To localize the bleeding site, we performed double balloon enteroscopy by the anal approach. A small, bleeding, polypoid lesion was found in the distal ileum and was successfully removed using endoscopic snare electrocautery. © 2013 Baishideng Publishing Group Co., Limited.

    Full Text Available Background. There has been a growing use of both capsule endoscopy (CE and double balloon enteroscopy (DBE to diagnose and treat patients with obscure gastrointestinal blood loss and suspected small bowel pathology. Aim. To compare and correlate sequential CE and DBE findings in a large series of patients at two tertiary level hospitals in Wisconsin. Methods. An IRB approved retrospective study of patients who underwent sequential CE and DBE, at two separate tertiary care academic centers from May 2007 to December 2011, was performed. Results. 116 patients were included in the study. The mean age ± SD was 66.6 ± 13.2 years. There were 56% males and 43.9% females. Measure of agreement between prior capsule and DBE findings was performed using kappa statistics, which gave kappa value of 0.396 with P<0.001. Also contingency coefficient was calculated and was found to be 0.732 (P<0.001. Conclusions. Our study showed good overall agreement between DBE and CE. Findings of angioectasia had maximum agreement of 69%.

    Full Text Available Background. The small intestine has been considered to be a highly difficult organ to visualize in imaging examinations due to its anatomical location compared with the stomach and the colon. In recent years, many imaging modalities have become available, such as CT enterography, MR enterography, capsule endoscopy (CE, and double-balloon endoscopy (DBE. Patients and Methods. DBE was performed in the postoperative intestines of 91 patients (128 DBE examinations at Iwate Medical University between 2004 and 2010. There were 61 male and 30 female patients, and their mean age was 69.7 years (range: 30–80 years. Results. A total of 124 DBE examinations were performed with endoscope insertion into the reconstructed intestines. The endoscope reached the blind end in 115 of 124 examinations, (92.7%. There were 17 patients with obscure gastrointestinal bleeding in whom 30 DBE examinations were performed. The bleeding site was identified in 12 patients (70.6%. Nine patients underwent endoscopic treatment. Hemostasis was achieved in all patients. Conclusion. DBE is very useful modality for the assessment and application of endotherapy to areas of the small bowel which have been altered by surgery.

    Primary intestinal lymphangiectasia is a disorder characterized by exudative enteropathy resulting from morphologic abnormalities of the intestinal lymphatics. Intestinal lymphangiectasia can be primary or secondary, so the diagnosis of primary intestinal lymphangiectasia must first exclude the possibility of secondary intestinal lymphangiectasia. A double-balloon enteroscopy and biopsy, as well as the pathology can be used to confirm the diagnosis of intestinal lymphangiectasia. A polymeric diet containing medium-chain triglycerides and total parenteral nutrition may be a useful therapy. A 17-year-old girl of Mongoloid ethnicity was admitted to our hospital with a history of diarrhea and edema. She was diagnosed with protein-losing enteropathy caused by intestinal lymphangiectasia. This was confirmed by a double-balloon enteroscopy and multi-dot biopsy. After treatment with total parenteral nutrition in hospital, which was followed by a low-fat and medium-chain triglyceride diet at home, she was totally relieved of her symptoms. Intestinal lymphangiectasia can be diagnosed with a double-balloon enteroscopy and multi-dot biopsy, as well as the pathology of small intestinal tissue showing edema of the submucosa and lymphangiectasia. Because intestinal lymphangiectasia can be primary or secondary, the diagnosis of primary intestinal lymphangiectasia must first exclude the possibility of secondary intestinal lymphangiectasia. A positive clinical response to the special diet therapy, namely a low-fat and medium-chain triglyceride diet, can further confirm the diagnosis of primary intestinal lymphangiectasia.

  3. Endoscopic ultrasound with double-balloon endoscopy for the diagnosis of inverted Meckel’s diverticulum: a case report

    2012-09-01

    Full Text Available Abstract Introduction Inverted Meckel’s diverticulum has usually been misdiagnosed in the cases based on computed tomography images presented in the literature. The final diagnosis was made intra-operatively or by pathology reports after surgery. Despite this, preoperative diagnosis could be made successfully by using endoscopic ultrasound with double-balloon endoscopy prior to surgery. Case presentation A 60-year-old Japanese woman with severe anemia complained of several episodes of black stool over the preceding 2 years. Abdominal computed tomography showed a 3.0-cm low-density tumor in the ileum, suggesting a diagnosis of intestinal lipoma. Examination of the tumor by endoscopic ultrasound with double-balloon endoscopy revealed a hypo-echoic layer corresponding to the muscularis propria, and a hyper-echoic layer corresponding to the fat tissue. These findings, which suggested that the tumor included areas outside the intestinal serosa, are not typical for a lipoma, despite the existence of a hyper-echoic layer corresponding to fatty tissue. We then considered a diagnosis of inverted Meckel’s diverticulum. Conclusion Lipoma and inverted Meckel’s diverticulum are difficult to differentially diagnose by computed tomography. Polypectomy is the preferred therapeutic approach when a lipoma is present; however, polypectomy in a patient with Meckel’s diverticulum requires full-thickness resection. Situations where polypectomy is performed without preparing for full-thickness resection can be avoided by first making a precise diagnosis using double-balloon endoscopy and endoscopic ultrasound.

    This study aims to evaluate the correlation of MRI findings with double-balloon urethrography (DBU) in diagnosing female urethral diverticula and other periurethral lesions. In this retrospective study, females with clinically suspected periurethral lesions who underwent both MRI and DBU between 2008 and 2012 were evaluated. MRI was performed on a 1.5 Tesla unit using a pelvic phased array coil. Protocol included small FOV pelvic images, multiplanar T2-w, T1-w with and without contrast injection. DBU was performed by a dedicated catheter. Images were evaluated in consensus by two readers. Diverticula were evaluated by, size, number, complexity, location and connection to urethra, and other periurethral lesions were evaluated by size, location and connection. Supplement clinical and surgical data were retrieved from medical records and telephone interviews. Seventeen females (mean age 44 years, range 20–69) were included in the study. Diverticula were diagnosed by both modalities (9 cases), by neither (6 cases, 88% correlation) by MRI alone (1 case) and by DBU alone (1 case). Among diverticula, correlation of number, complexity, location and demonstration of connection to urethra was 89%, 67%, 67%, and 56%, respectively. Alternative diagnosis solely by MRI included vaginal wall cysts (3 cases), endometriosis (1 case) and ectopic ureter (1 case). No periurethral lesion was found by either modality in 2 cases. The correlation between MRI and DBU in diagnosing female periurethral lesions is very good for anatomical delineation of diverticula. MRI, which does not involve radiation, may also indicate alternative diagnoses that can contribute to proper patient management.

    AIM: To clarify clinical features of the NSAID-induced small bowel lesions using a new method of endoscopy. METHODS: This is a retrospective study and we analyzed seven patients with small bowel lesions while taking NSAIDs among 61 patients who had undergone double-balloon endoscopy because of gastro-intestinal bleeding or anemia between September 2000 and March 2004, at Jichi Medical School Hospital in Japan. Neither conventional EGD nor colonoscopy revealed any lesions of potential bleeding sources including ulcerations. Double-balloon endoscopy was carried out from oral approach in three patients, from anal approach in three patients, and from both approaches in one patient. RESULTS: Ulcers or erosions were observed in the ileum in six patients and in the jejunum in one patient, respectively. The ulcers were multiple in all the patients with different features from tiny punched out ulcers to deep ulcerations with oozing hemorrhage or scar. All the patients recovered uneventfully and had full resolution of symptoms after suspension of the drug. CONCLUSION: NSAIDs can induce injuries in the small bowel even in patients without any lesions in both the stomach and colon. PMID:16097059

    Full Text Available Primary intestinal lymphangiectasia (PIL or Waldmann′s disease is a rare protein-losing enteropathy presenting with diarrhea. The etiology and prevalence of PIL remain unknown. <200 cases have been reported in the literature so far. Diagnosis of intestinal lymphangiectasia is difficult as there are no serological or radiological tests available. Small bowel imaging modalities like capsule endoscopy and double balloon enteroscopy have increased the chances of diagnosis of PIL due to direct visualization of small bowel. Diagnosis is confirmed by characteristic histopathological finding, which includes dilated intestinal lymphatics with broadened villi of the small bowel. We report a case of a patient with chronic diarrhea who was extensively worked up before he was finally diagnosed to have PIL involving the small bowel by performing balloon enteroscopy-guided biopsy.

    The introduction of the balloon remodeling and stent-assisted technique has revolutionized the approach to coil embolization for wide-neck aneurysms. The purpose of this study was to determine the frequency of thromboembolic events associated with single balloon-assisted, double balloon-assisted, and stent-assisted coil embolization for asymptomatic unruptured aneurysms. A retrospective review was undertaken by 119 patients undergoing coiling with an adjunctive technique for unruptured saccular aneurysms (64 single balloon, 12 double balloon, 43 stent assisted). All underwent diffusion-weighted imaging (DWI) within 24 h after the procedure. DWI showed hyperintense lesions in 48 (40 %) patients, and ten (21 %) of these patients incurred neurological deterioration (permanent, two; transient, eight). Hyperintense lesions were detected significantly more often in procedures with the double balloon-assisted technique (7/12, 58 %) than with the single balloon-assisted technique (16/64, 25 %, p = 0.05). Occurrence of new lesions was significantly higher with the use of stent-assisted technique (25/43, 58 %) than with the single balloon-assisted technique (p = 0.001). Symptomatic ischemic rates were similar between the three groups. The increased number of microcatheters was significantly related to the DWI abnormalities (two microcatheters, 15/63 (23.8 %); three microcatheters, 20/41 (48.8 %) (p = 0.008); four microcatheters, 12/15 (80 %) (p = 0.001)). Thromboembolic events detected on DWI related to coil embolization for unruptured aneurysms are relatively common, especially in association with the double balloon-assisted and stent-assisted techniques. Furthermore, the number of microcatheters is highly correlated with DWI abnormalities. The high rate of thromboembolic events suggests the need for evaluation of platelet reactivity and the addition or change of antiplatelet agents. (orig.)

    The preoperative work-up of female urethral diverticula should provide the surgeon with maximum data regarding the anatomy and structure of the diverticulum. Preoperatively, the number of diverticula, as well as the location, size, configuration, and communication to the urethra need to be clearly depicted. The objective of this study was to compare the information gained by voiding cystourethrography (VCUG) and positive-pressure double-balloon urethrography (DBU), and to verify which imaging modality can better delineate the features of the diverticula. Twelve women with a presumptive clinical diagnosis of a urethral diverticulum underwent VCUG followed by DBU, and the radiological data from each modality were compared. In 4 of 12 patients (33.3%) VCUG completely failed in demonstrating the diverticulum, whereas DBU showed a large complex diverticulum in 2 patients and a distinct mid-urethral diverticulum in 2 patients. In the remaining 8 women (66.7%) VCUG delineated only the lower part of the diverticulum, whereas DBU depicted a large diverticulum extending beneath the bladder neck in 3 patients and multiple diverticula in 5 patients. The sensitivity of DBU and VCUG, in our series, was therefore 100 and 66.7%, respectively. The DBU supplied excellent documentation regarding the location, size, configuration, and communication of the diverticula to the urethra in every case, which markedly facilitated surgical excision of the diverticula in 9 of 12 patients. Three patients refused surgery and elected conservative treatment. In our experience, VCUG had a low sensitivity as a screening test for the diagnosis of female urethral diverticula, and failed to demonstrate properly the major structural characteristics of the diverticula, whereas DBU was highly sensitive as a diagnostic tool and supplied excellent anatomical delineation of the diverticula.

    The utility of conventional short-type double-balloon endoscopy (DBE) for pancreatobiliary disease in patients with postoperative anatomy had been widely acknowledged and accepted. However, some technical difficulties yet remained. In an attempt to solve these problems, the new short-type DBE (N-short DBE) was uniquely designed for therapeutic endoscopic retrograde cholangiography (ERC) in postoperative patients. The aim of this study was to evaluate the usefulness of N-short DBE for ERC in postoperative patients. From August 2015 to April 2016, ERC using N-short DBE (DB-ERC) was performed in 100 postoperative patients (112 procedures). We retrospectively studied the success rate of reaching the blind end, the median time to reach the blind end, the diagnostic success rate, the therapeutic success rate, the median time to complete ERC-related interventions, the overall success rate, the median time to complete DB-ERC, and adverse events. The success rate of reaching the blind end was 99.1%. The median time to reach the blind end was 10 min (interquartile range [IQR], 6-19 min). The diagnostic success rate was 98.2%. The therapeutic success rate was 100%. The median time to complete ERC-related interventions was 36 min (IQR, 22-62 min). The overall DB-ERC success rate was 97.3%. The median time to complete DB-ERC was 54 min (IQR, 37-73 min). The occurrence of adverse events was 2.7%. The N-short DBE for ERC in postoperative patients is useful and safe. DB-ERC is promising therapeutic modality in such patients and should be selected as the first-line policy. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Full Text Available Pancreatic and gastric heterotopias are rare clinical entities which have been identified throughout the entire length of the gastrointestinal tract. Combined gastric and pancreatic heterotopias, although unusual, have been described in the duodenum and jejunum, and in other structures, including Meckel's diverticulum and the ampulla of Vater. We report a novel case of pancreatic and gastric heterotopia with an associated submucosal lipoma in a 38-year-old female with a recent history of rectal cancer and chronic crampy abdominal pain. On computed tomography, a 7-cm luminal polypoid mass extending into the distal ileum was discovered. The mass was successfully resected using retrograde double balloon enteroscopy. We believe this is the first report of all three histological entities co-existing in an obstructive ileal lesion in an adult. It highlights endoscopic resection trough double enteroscopy as a safe alternative to more invasive surgical approaches for this type of lesion.

    To compare the efficacy of double-balloon enteroscopy (DBE) and single-balloon enteroscopy (SBE) in therapeutic endoscopic retrograde cholangiography (ERC) in patients with Roux-en-Y entero-enteric anastomosis. Retrospective analysis of our patient cohort revealed 4 patients with enterobiliary anastomosis and Roux-en-Y entero-enteric anastomosis who underwent repeated ERC with DBE and SBE because of recurrent cholangitis. A total of 38 endoscopic retrograde cholangiopancreatography procedures were performed in 25 patients with Roux-en-Y entero-enteric anastomosis. DBE was used in 29 procedures and SBE in 9. The 4 patients who underwent repeated ERC with DBE and SBE suffered from recurrent cholangitis due to stenosis of the enterobiliary anastomosis. ERC was performed repeatedly to achieve balloon dilation with/without biliary stone extraction and multiple stent placement at the level of the enterobiliary anastomosis. In all 4 patients DBE and SBE were equally successful. Compared to DBE, SBE was equally effective in passing the Roux-en-Y entero-enteric anastomosis, reaching the enterobiliary anastomosis and performing therapeutic ERC. This retrospective comparison shows that DBE and SBE are equally successful in the performance of therapeutic ERC at the level of the enterobiliary anastomosis after Roux-en-Y entero-enteric anastomosis.

    Full Text Available Aim: to evaluate the utility of double-balloon enteroscopy for small-bowel disease. Design: a prospective study of 50 consecutive enteroscopies performed from December 2004 to July 2005 to analyze diagnoses and treatments. Patients: 44 patients (33 had undergone a previous capsule endoscopy with indications for obscure digestive hemorrhage, angiodysplasia, Peutz-Jeghers syndrome, ulcer, suspected Crohn's disease, tumors, and refractory celiac disease. Results: we carried out enteroscopy studies in 44 patients by the oral route and, in 6 additional patients, by both the oral and anal routes. We reached the ileon with the oral route in all cases but one (jejunal stenosis, and in 4 cases out of 7 with the anal route, with an average duration of 73 minutes. We found angiodysplasia in 19 cases, as well as NSAID-related enteropathy, Crohn's disease, diverticulosis, and Waldenström's disease. We performed biopsies in 31% of cases with diagnoses of adenocarcinoma, lymphangiectasia secondary to tumor in celiac disease, and Whipple's disease. We treated 19 patients with angiodysplasia (1 to 20 synchronous lesions with argon, and 4 patients with polyps using polipectomy (sporadic polyps or Peutz-Jeghers syndrome. A retained capsule in one patient with stenosis was removed. Conclusions: double-balloon enteroscopy is a useful and effective technique in the diagnosis and treatment of small intestine diseases, thus complementing capsule endoscopy. More studies are needed to analyze its impact on the management of this condition.Objetivo: valorar la utilidad de la enteroscopia de doble balón en enfermedades de intestino delgado.

    In patients with Roux-en-Y hepaticojejunostomy (HJ with R-Y) and Whipple resection, endoscopic retrograde cholangiopancreatography (ERCP) can be challenging. We report our experience with ERCP using balloon-assisted enteroscopy (BAE) (BAE-ERCP) in patients with HJ with R-Y, and Whipple resection. BAE-ERCP procedures were carried out in 62 patients (HJ with R-Y:Whipple resection=34:28). Overall, the rates of reaching the anastomosis were 85.3% (29/34) in HJ with R-Y and 96.4% (27/28) in Whipple resection. In terms of HJ with R-Y, insertion success rate by standard single-balloon enteroscopy (SBE) was 89.3% (25/28). Insertion success rate by short BAE, including SBE and double-balloon enteroscopy (DBE), was 50% (3/6). There was a statistically significant difference of insertion success rate between standard long BE and short BE (P=0.021). However, in the Whipple patients, insertion success rate by standard and short SBE was 93.8% (15/16) and 91.7% (11/12), respectively. Initial insertion success rate by short BAE in Whipple patients was significantly higher than in HJ with R-Y (91.7% vs 50%, P=0.045). Therapeutic interventions included dilation of anastomosis stricture, stone extraction, endoscopic mechanical lithotripsy, biliary stent placement, stent extraction, endoscopic nasobiliary drainage, direct cholangioscopy, and electrohydraulic lithotripsy. Our HJ with R-Y series and Whipple series treatment success rate was 90% (18/20) and 95.0% (19/20), respectively. BAE-ERCP enabled ERCP to be carried out in patients with HJ. It is considered safe and feasible. Further experience and device improvement are needed. © 2014 The Authors. Digestive Endoscopy © 2014 Japan Gastroenterological Endoscopy Society.

    We describe multiparametric monitoring in severe head trauma using a new screwing device. Our aim was to create a screw which would make the implantation of the probes and thus multiparametric monitoring easier. The new screw allows us to implant 3 probes (microdialysis, Paratrend and an intracranial pressure device) through one burr hole. The screw has four channels, the fourth being for ventricular drainage. We monitored 13 patients with severe head trauma (GCS = 3-8) for up to 7 days. Brain tissue pO2, pCO2, pH, and temperature were measured on-line with the Paratrend 7 machine. The microdialytic parameters glucose, lactate, pyruvate and glutamate were determined semi on-line with a CMA 600 enzymatic analyser. There were no complications in any of the patients that could be ascribed to the screw.

    PurposeApproximately 83 % of patients with bladder cancer have achieved a complete response after undergoing a novel bladder preservation therapy involving balloon-occluded intra-arterial infusion chemotherapy (BOAI) using a four-lumen double-balloon catheter, known as the Osaka Medical College regimen. This study aimed to show the quantitative difference in hemodynamics of the bladder arteries using syngo iFlow (Siemens Healthcare, Erlangen, Germany), which provides an automatic tool for quantitative blood flow analysis between double BOAI (D-BOAI) and conventional single BOAI (S-BOAI).Materials and MethodsFifty patients were included. The catheters were introduced into both posterior trunks of the internal iliac arteries via contralateral femoral artery access. A side hole between the distal and proximal balloons was placed at the origin of each bladder artery to allow clear visualization of angiographic flow of the injected agent into the urinary bladder. Digital subtraction angiography was used during analysis with the syngo iFlow to evaluate the hemodynamics of the contrast medium in the pelvic arteries during BOAI. The comparative change in the amount of contrast medium in the bladder arteries between D-BOAI and S-BOAI was assessed using syngo iFlow.ResultsOne-hundred pelvic sides were analyzed. The amount of contrast medium in the bladder arteries using D-BOAI was more than twice that using S-BOAI (right, 3.03-fold; left, 2.81-fold).ConclusionThe amount of contrast medium in the bladder arteries using D-BOAI was higher than that using conventional S-BOAI. This may increase the anticancer drug concentration in the affected bladder, leading to a good clinical response.

    Distal embolism is an important periprocedural technical complication with carotid angioplasty and carotid artery stenting (CAS). We evaluated the safety and efficacy of protection devices used during CAS by detecting new cerebral ischemic lesions using diffusion-weighted magnetic resonance imaging in 95 patients who underwent 98 CAS procedures: 34 using single PercuSurge GuardWire, 31 using double balloon protection, 15 using proximal flow reverse protection devices, 14 using Naviballoon, and 4 using filter anti-embolic devices. Diffusion-weighted imaging was performed preoperatively and postoperatively to evaluate the presence of any new embolic cerebral lesions. Postoperative diffusion-weighted imaging revealed 117 new ischemic lesions. Three patients had new ischemic stroke, two minor and one major, all ipsilateral to the treated carotid artery. The remaining patients had clinically silent ischemia. The incidence of new embolic lesions was lower using the proximal flow reverse protection device than with the double balloon protection (33% vs. 48.4%), but the volume of ipsilateral new ischemic lesions per patient was 136.6 mm 3 vs. 86.9 mm 3 , respectively. Neuroprotection with Naviballoon yielded ipsilateral lesions of large volume (86.6 mm 3 ) and higher number (5.7 lesions per patient) than using the filter anti-embolic device (34.8 mm 3 and 1 lesion per patient). New cerebral ischemic lesions after neuroprotected CAS are usually silent. The lower incidence of distal ischemia using proximal flow reverse and double balloon protection devices is limited by the larger volume and higher number of ischemic lesions. (author)

    Distal embolism is an important periprocedural technical complication with carotid angioplasty and carotid artery stenting (CAS). We evaluated the safety and efficacy of protection devices used during CAS by detecting new cerebral ischemic lesions using diffusion-weighted magnetic resonance imaging in 95 patients who underwent 98 CAS procedures: 34 using single PercuSurge GuardWire, 31 using double balloon protection, 15 using proximal flow reverse protection devices, 14 using Naviballoon, and 4 using filter anti-embolic devices. Diffusion-weighted imaging was performed preoperatively and postoperatively to evaluate the presence of any new embolic cerebral lesions. Postoperative diffusion-weighted imaging revealed 117 new ischemic lesions. Three patients had new ischemic stroke, two minor and one major, all ipsilateral to the treated carotid artery. The remaining patients had clinically silent ischemia. The incidence of new embolic lesions was lower using the proximal flow reverse protection device than with the double balloon protection (33% vs. 48.4%), but the volume of ipsilateral new ischemic lesions per patient was 136.6 mm(3) vs. 86.9 mm(3), respectively. Neuroprotection with Naviballoon yielded ipsilateral lesions of large volume (86.6 mm(3)) and higher number (5.7 lesions per patient) than using the filter anti-embolic device (34.8 mm(3) and 1 lesion per patient). New cerebral ischemic lesions after neuroprotected CAS are usually silent. The lower incidence of distal ischemia using proximal flow reverse and double balloon protection devices is limited by the larger volume and higher number of ischemic lesions.

    Full Text Available Obscure gastrointestinal bleeding (OGIB can present as a diagnostic dilemma and management can be challenging. The search for causes of OGIB is usually centered on visualizing the small bowel, and in the past decade, the technology to visualize the entire small bowel has significantly advanced. Moreover, small bowel endoscopic imaging has replaced, in many instances, prior radiographic evaluation for obscure GI bleeding. These new modalities, such as small bowel capsule endoscopy (CE, balloon-assisted deep enteroscopy [double balloon enteroscopy (DBE and single balloon enteroscopy (SBE], and overtube-assisted deep enteroscopy (spiral enteroscopy, are paving the way toward more accurately identifying and treating patients with OGIB. We will review the diagnostic modalities available in evaluating a patient with OGIB and also propose the management based on clinical and endoscopic findings.

    Primary intestinal lymphangiectasia (PIL), also known as Waldmann's disease, is a rare disorder characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen and responsible for protein-losing enteropathy leading to lymphopenia, hypoalbuminemia and hypogammaglobulinemia. The symptoms usually start in early infancy. We report a case of secondary hyperparathyroidism, osteopenia, monoclonal gammopathy and digital clubbing in a 57-year-old patient with a 12-year history of discontinuous diarrhea. Malabsorption with inability to gain weight, and finally weight loss and formation of leg edema were associated with protein-losing enteropathy. A low-fat diet associated with medium-chain triglyceride supplementation was clinically effective as medical management in reducing diarrhea and leg edema, and promoting weight gain. Double-balloon enteroscopy and small bowel biopsy histopathology confirmed dilated intestinal lacteals. Digital clubbing associated with primary intestinal lymphangiectasia which may causally be related to chronic platelet excess has not been reported before.

    A 55-year-old man with hepatitis B virus antigen-positive liver cirrhosis was admitted to our hospital with anal bleeding. Colonoscopy revealed blood retention in the entire colon, but no bleeding lesion was found. Computed tomography images showed that vessels in the ileum were connected to the right testicular vein, and we suspected ileal varices to be the most probable cause of bleeding. We immediately performed double balloon enteroscopy, but failed to find any site of bleeding owing to the difficulty of fiberscope insertion with sever adhesion. Using a balloon catheter during retrograde transvenous venography, we found ileal varices communicating with the right testicular vein (efferent vein) with the superior mesenteric vein branch as the afferent vein of these varices. We performed balloon occluded retrograde transvenous obliteration by way of the efferent vein of the varices and have detected no further bleeding in this patient one year after treatment.

    Aims/hypothesis: Enteroendocrine K and L cells are pivotal in regulating appetite and glucose homeostasis. Knowledge of their distribution in humans is sparse and it is unknown whether alterations occur in type 2 diabetes. We aimed to evaluate the distribution of enteroendocrine K and L cells...... and relevant prohormone-processing enzymes (using immunohistochemical staining), and to evaluate the mRNA expression of the corresponding genes along the entire intestinal tract in individuals with type 2 diabetes and healthy participants. Methods: In this cross-sectional study, 12 individuals with type 2...... diabetes and 12 age- and BMI-matched healthy individuals underwent upper and lower double-balloon enteroscopy with mucosal biopsy retrieval from approximately every 30 cm of the small intestine and from seven specific anatomical locations in the large intestine. Results: Significantly different densities...

    2014-10-01

    Full Text Available Gastrointestinal bleeding that originates in the small intestine is often difficult to diagnose. When successful diagnosis reveals a lesion that can be localized preoperatively, the laparoscopic approach is an appropriate and beneficial treatment modality for small bowel resection. A 69-year-old man presented with a 6-month history of gastrointestinal bleeding and symptomatic transfusion-dependent anemia. Upper and lower endoscopy were normal. Double-balloon endoscopy established the source of the bleeding as a 0.5-cm polypoid mass appearing as a submucosal tumor with redness and pulsation in the lower ileum, suggesting a vascular lesion. Laparoscopic small bowel resection was successful in removing the mass in the ileum. Histological evaluation of the mass revealed an arteriovenous malformation. Preoperative small bowel endoscopy can be useful for diagnosing the cause and localization of arteriovenous malformation in the small intestine.

    Abstract: Patients diagnosed with primary or metastatic liver cancer face a daunting future that is complicated by limited treatment options. Percutaneous hepatic perfusion is a novel approach to chemotherapy delivery that offers significant benefits over contemporary modalities. Percutaneous hepatic perfusion is a procedure in which a chemotherapeutic agent is administered at high doses via the hepatic artery where it perfuses the liver, is extracted and filtered using a veno-veno bypass circuit, a fenestrated multi-lumen double-balloon catheter, and two biocompatible hemoperfusion filters. Venous access is gained at the groin through the femoral vein after which the catheter is advanced and positioned in the inferior vena cava just below the right atrium. The catheter’s proximal and distal balloons are inflated to occlude the inferior vena cava above and below the hepatic veins. The occlusion isolated the chemo-rich venous outflow of the liver from the systemic venous circulation. This maneuver also diverts venous blood returning to the heart from lower extremities of the azygos vein. Once the patient is on bypass, the agent is infused through the hepatic artery where it saturates the liver. The chemorich venous outflow is extracted through the double-balloon catheter by the bypass circuit. The blood is continuously filtered and cleared of the agent as it passes through the filters and returned to the patient through a catheter placed in the right internal jugular vein. A phase I study demonstrated efficacy with an overall radiographic response rate of 30% observed in treated patients. In 10 patients with ocular melanoma, a 50% overall response rate was observed, including two complete responses. The technique is minimally invasive and can be performed safely by a well-trained multi-disciplinary team. It offers significant benefits including multiple procedures without risks commonly associated with open abdominal surgery. PMID:21449232

    Full Text Available Double balloon enteroscopy (DBE is a revolutionary procedure in which the entire small bowel can be visualized endoscopically. DBE has the advantage of both diagnostic and therapeutic capabilities in the setting of small bowel neoplasms and vascular malformations. We present a unique case of a 76-year-old female who underwent small bowel DBE tattoo marking of a distal small bowel tumor complicated by development of severe abdominal pain postprocedure secondary to bowel air embolism into the mesenteric veins. Mesenteric air can be seen after other endoscopic procedures such as biopsy, mucosal clip placement and polypectomy, or following a colonoscopy. Mesenteric air embolism following small bowel tattooing procedure has not been previously reported in the literature. Mesenteric air when present may be attributed to mesenteric ischemia and can subject the patient to unnecessary surgical intervention if misdiagnosed. Thus, this report holds significance for the radiologist as computed tomography (CT findings of mesenteric air embolism must be evaluated in the context of appropriate clinical history before treatment decisions are made.

    Full Text Available In the era of double balloon enteroscopy, capsule endoscopy, CT, and MRI enterography is transabdominal ultrasonography (TUS underestimated method for evaluation of small bowel pathology. As often initial imagine method in abdominal complaints, nowadays has TUS much better diagnostic potential than two decades ago. High-resolution ultrasound probes with harmonic imaging significantly improve resolution of bowel wall in real time, with possibility to asses bowel peristalsis. Color flow doppler enables evaluation of intramural bowel vascularisation, pulse wave doppler helps to quantificate flow in coeliac and superior mesenteric arteries. Small intestine contrast ultrasonography with oral contrast fluid, as well as contrast enhanced ultrasonography with intravenous microbubble contrast also improves small bowel imaging. We present a review of small intestine pathology that should be detected during ultrasound examinations, discuss technical requirements, advantages and limitations of TUS, typical ultrasound signs of Crohn's disease, ileus, celiac disease, intussusception, infectious enteritis, tumours, ischemic and haemorrhagic conditions of small bowel. In the hands of experienced investigator, despite some significant limitations(obesity, meteorism, is transabdominal ultrasonography reliable, noninvasive and inexpensive alternative method to computerised tomography (CT and magnetic resonance imaging (MRI in small bowel examination.

    Objective: Experimental study of the mechanism in esophageal restenosis after balloon dilation of benign stricture. Methods: Esophageal stenosis model of the rats was created by 5 ml of 50% NaOH solution burn with double balloon method, and esophageal restenosis (RS) model was developed by esophageal stenosis with dilation of PTCA balloon catheter. Quantitative and quantitative analysis of esophageal stenosis and RS formation in the rats were observed and recorded by analytic measurements imaging and immuno-histologic chemistry respectively. Results: Esophageal benign stricture and RS model of 49 rats were developed. Cross section area and perimeter of esophageal mucosa layer, muscular layer and the whole layer had increased in experimental group. Comparing to control group, it had remarkable significance in statistics (P < 0.05). PCNA was expressed in 5th day after dilation, and persisted to 1st month. FN was expressed in the 1st day after dilation, still positive on 21st days, partly strong on 30th day. Conclusions: The continued over secretion at all stage of PCNA and FN plays an important role in the RS after balloon dilation of esophageal benign stenosis

    Meckel’s diverticulum (MD) is estimated to affect 1%-2% of the general population, and it represents a clinically silent finding of a congenital anomaly in up to 85% of the cases. In adults, MD may cause symptoms, such as overt occult lower gastrointestinal bleeding. The diagnostic imaging workup includes computed tomography scan, magnetic resonance imaging enterography, technetium 99m scintigraphy (99mTc) using either labeled red blood cells or pertechnetate (known as the Meckel’s scan) and angiography. The preoperative detection rate of MD in adults is low, and many patients ultimately undergo exploratory laparoscopy. More recently, however, endoscopic identification of MD has been possible with the use of balloon-assisted enteroscopy via direct luminal access, which also provides visualization of the diverticular ostium. The aim of this study was to review the diagnosis by double-balloon enteroscopy of 4 adults with symptomatic MD but who had negative diagnostic imaging workups. These cases indicate that balloon-assisted enteroscopy is a valuable diagnostic method and should be considered in adult patients who have suspected MD and indefinite findings on diagnostic imaging workup, including negative Meckel’s scan.

    2018-01-01

    Full Text Available Introduction. Primary intestinal lymphangiectasia is a rare disorder, characterized by abnormal dilation of intestinal lymphatic vessels and extensive enteric loss of lymph rich in plasma proteins, lymphocytes and chylomicrons. The main characteristics of the disease are hypoalbuminemia, hypogammaglobulinemia, lymphocytopenia, and more rarely, the deficit of liposoluble vitamins and anemia. Except for primary, there are secondary lymphangiectasia, associated with celiac disease, malignant, infective and inflammatory diseases of the small intestine, fibrosis, liver and cardiovascular diseases. Case report. A male, 33 years of age, presented for his medical examination suffering from diarrhea and edema. The diagnosis was established upon the histological examination of a small intestine biopsy during double balloon enteroscopy, which revealed changes only in one segment of the intestine examined. Such a finding was later confirmed by the video endoscopy capsule. Conclusion. The diagnosis of intestinal lymphangiectasia is usually established before the age of 3, but it can also be diagnosed in adults. The diagnosis is based on the histological analysis of the intestinal mucosa biopsy, obtained by endoscopic procedures. The diagnosis of primary intestinal lymphangiectasia is also made upon the exclusion of secondary causes.

    We classified intestinal lymphangiectasia (IL) into two categories, the white and non-white villi types, and evaluated their clinical characteristics and therapeutic responses. Of the 988 patients who underwent double-balloon enteroscopy, 14 consecutive patients (7 men and 7 women, median age at onset 34 years) were enrolled with immunohistochemically confirmed IL with protein-losing enteropathy. Enteroscopically the white villi type (n = 8) showed white plaques and white-tipped villi were scattered in the small bowel, while non-white villi type (n = 6) showed that apparently normal but under more detailed observation, low and round villi with a normal color were diffused. The serum albumin levels and fecal α1-antitrypsin clearance before treatment were significantly worse in the non-white villi type (p = 0.017 and 0.039, respectively), whereas the serum immunoglobulin A and M levels were significantly lower in the white villi type (p = 0.010 and 0.046, respectively). At gastroscopy, a non-cirrhotic snakeskin appearance was significantly observed in the non-white villi type (p = 0.015). The corticosteroid response was better in the non-white villi type (p = 0.015). Two distinct subgroups were found in IL. This classification was useful in pathophysiological clustering and in predicting the therapeutic response. © 2014 S. Karger AG, Basel.

    Primary idiopathic intestinal lymphangiectasia is an unusual disease featured by the presence of dilated lymphatic channels which are located in the mucosa, submucosa or subserosa leading to protein loosing enteropathy.Most often affected were children and generally diagnosed before third year of life but may be rarely seen in adults too. Bilateral pitting oedema of lower limb is the main clinical manifestation mimicking the systemic disease and posing a real diagnostic dilemma to the clinicians to differentiate it from other common systemic diseases like Congestive cardiac failure, Nephrotic Syndrome, Protein Energy Malnutrition, etc. Diagnosis can be made on capsule endoscopy which can localise the lesion but unable to take biopsy samples. Thus, recently double-balloon enteroscopy and biopsy in combination can be used as an effective diagnostic tool to hit the correct diagnosis. Patients respond dramatically to diet constituting low long chain triglycerides and high protein content with supplements of medium chain triglyceride. So early diagnosis is important to prevent untoward complications related to disease or treatment for the sake of accurate pathological diagnosis. PMID:25325063

    To determine whether the Bishop-score upon admission effects mode of delivery, maternal or neonatal outcomes of labor induction in multiparous women. A retrospective study including 600 multiparous women with a singleton pregnancy, 34 gestational weeks and above who underwent labor induction for maternal, fetal or combined indications. Induction was performed with one of three methods- oxytocin, a slow release vaginal prostaglandin E2 insert (10 mg dinoprostone) or a transcervical double balloon catheter. The women were divided into two groups-Bishop-score manual lysis, uterine revision, perineal tear grade 3-4, need for blood transfusions, relaparotomy, prolonged hospitalization) and neonatal outcomes (Apgar score, cord pH, hospitalization in the neonatal intensive care unit, prolonged hospitalization). Both groups had a high rate of vaginal deliveries-93.7% and 94.9%, respectively. There was no difference between the two groups in terms of maternal or neonatal outcomes. Labor induction in multiparous women is safe and successful regardless of the initial Bishop-score. In multiparous women the Bishop-score is not a good predictor for the success of labor induction, nor is it a predictor for maternal of neonatal adverse outcomes and complications.

  5. An unusual case of giant ileal diverticulum–A case report

    Fang Ju Koh

    Full Text Available Small bowel diverticulosis is rare with an incidence of 1–2% in the general population. It is an uncommon cause of gastrointestinal bleeding that ranges from obscure to overt bleeding. Large ileal diverticula are extremely rare and bleeding complications can result in high overall mortality.A young gentleman presented with persistent per-rectal bleeding and drop in hemoglobin level. He was recently diagnosed with acute myeloid leukemia and was undergoing chemotherapy. A computed tomography scan of the abdomen and pelvis revealed a giant ileal diverticulum. In view of on-going bleeding, he underwent double balloon enteroscopy which revealed active bleeding from an ulcer within the giant ileal diverticulum and successful hemostasis was performed with hemostatic clips.Small bowel diverticulosis though uncommon has to be considered during workup for gastrointestinal bleeding. Endoscopic treatment is a modern approach towards small bowel diverticular bleeding that is effective and less invasive.

    Full Text Available Background: Carbon dioxide (CO 2 insufflation has been shown to be superior to air insufflation in colonoscopy, and double balloon enteroscopy. However, the value of CO 2 insufflation in endoscopic retrograde cholangiopancreatography (ERCP is not established. This study aims to assess the efficacy and safety of CO 2 insufflation during ERCP. Materials and Methods: Consecutive patients referred for ERCP at a single center were randomized to either air or CO 2 insufflation during ERCP. The primary objectives were a post-ERCP abdominal pain (measured by 10 cm visual analog scale [VAS] 30 and 90 min, and 3 h and 24 h after ERCP. Secondary objectives included end-tidal CO 2 (ETCO 2 values and procedural complications. Results: We randomized 298 patients; 149 into air group and 149 into CO 2 group. The VAS score for pain was higher in the air group compared to the CO 2 group at 30 min, with a median of 1 (interquartile range 1-0 versus median of 1 (interquartile range 1-0; P = 0.031 and 90 min after the procedure with a median of 0 (interquartile range 1-0 versus median of 0 (interquartile range 0-0; P = 0.006. There were no serious adverse events, and the ETCO 2 was within normal limits in both groups. Conclusions: CO 2 insufflation is superior to air insufflation during ERCP with regard to patient pain and discomfort and warrants wide adoption.

    In the 1980s and 1990s in North America and Europe, air (CO(2)) double-contrast barium enteroclysis took a back seat to biphasic methylcellulose double-contrast enteroclysis in the investigation of small-bowel diseases. The widespread application of capsule endoscopy in the 21st century has identified a number of limitations of radiologic examinations in the investigation of mucosal diseases of the small intestine. Evidence-based studies comparing barium, computed tomographic (CT), and magnetic resonance (MR) enteroclysis have shown that in spite of improvements in small-bowel examination methods using CT and MR, barium examinations remain superior in the depiction of mucosal abnormalities, particularly the apthoid lesions of early Crohn disease. Barium small-bowel examinations have been recommended in the patient with a negative CT or MR enteroclysis study where the pretest probability of Crohn disease is high. A recent prospective comparison of methylcellulose double-contrast barium enteroclysis to capsule endoscopy with review of the literature has shown that air enteroclysis depicts mucosal details better than does methylcellulose double-contrast enteroclysis because of the "washout" effect of methylcellulose on superficial mucosal features. Recent articles have shown that air enteroclysis compares favorably with wireless capsule endoscopy and double-balloon endoscopy in the diagnosis of mucosal abnormalities of the small bowel. This article describes the authors' technique of performing air double-contrast enteroclysis, its clinical indications, and its pitfalls.

    Recently, a new urodynamic method for the assessment of stress urinary incontinence called high definition urethral pressure profilometry (HD-UPP) has been introduced. This method combines a novel microtip catheter with advanced signal processing to enable spatial data location and the reconstruction of a pressure image inside the urethra. In order to assess the reproducibility of HD-UPP data, we statistically evaluate HD-UPP datasets and compare them to data from a double balloon air-charged system. Both catheters are used on sedated female minipigs. Data from the microtip catheter are processed through a signal reconstruction algorithm, urodynamic features are extracted, and compared to the air-charged system. Reproducibility of HD-UPP data is assessed by statistically evaluating consecutive, intra-individual datasets. HD-UPP delivers results in agreement with previous comparisons of microtip and air-charged systems. The average deviation of two consecutive, intra-individual pressure images is very low at 7 cm H 2 O. HD-UPP provides physicians with detailed information on the pressure distribution inside the urethra. Through comparison with an air-charged catheter, it is shown that HD-UPP delivers results in agreement with previous studies on the comparison of microtip and air-charged catheters. It provides excellent reproducibility, as the difference between sequentially measured profiles from the same minipig is significantly lower than the one between profiles from different minipigs. © 2016 Wiley Periodicals, Inc.

    The purpose of this study is to report our 5 year experience with fluoroscopic removal of blunt esophageal foreign body or impacted food in 15 consecutive patients who were referred by endoscopists because they couln't remove it endoscopically. The foreign body or impacted food was a piece of meat, a bean, a badug stone or a beef bone. Thirteen patients had underlying disease (11 of corrosive stricture, 2 of postopertive stricture) but 2 patient did not. We removed the object using one of the following 4 techniques: Basket extraction technique. Foley catheter technique, single balloon technique (dilatation of stenosis for passing the food into the stomach and for the treatment of the stricture as well), double balloon technique (removal of the foregin body by trapping it with two valvuloplasty balloons). Removal was successful in all patients. Esophageal performation occurred in one patient using the sibgle balloon technique, who treated nonoperatively by means of fasting, antibiotics and parenteral alimentation. No procedure related death occurred in these series. In conclusion, fliuroscopic removal of blunt esophageal foreign bodies of impacted food with various techniques is promising alternative to esophagoscopic removal

    Small bowel tumors (SBTs), either benign or malignant, are rare, accounting for 3-6% of all digestive neoplasms. Videocapsule endoscopy (VCE) and double-balloon enteroscopy (DBE) have revolutionized the diagnosis and management of patients with small bowel diseases, including SBTs. A novel method using the single-balloon enteroscopy (SBE) has recently been developed. The aim of present study was to present our preliminary experience with SBE in patients with suspected SBTs on VCE examination. Patients in whom VCE showed one or more lesions suggesting SBTs underwent SBE. Three patients (2 males, 1 female; mean age 52 +/- 11 years) underwent SBE, and then surgery. There were two gastrointestinal stromal tumors and one adenocarcinoma. Clinically, all patients had iron-deficiency anemia and abdominal pain, and one patient had episodes of nausea/ vomiting. SBE was well tolerated without adverse events. SBE is a safe procedure and overcomes the limitations of VCE. Both procedures are complimentary in patients with suspected SBTs. VCE should be used first for initial diagnosis, followed by SBE for histopathological confrmation of the diagnosis and, if necessary, endoscopic therapy.

    Full Text Available Introduction. Gastrointestinal stromal tumor (GIST in the ileum is an extremely rare cause of recurrent lower gastrointestinal bleeding (GIB. Case Report. An 89-year-old man was admitted with melana. He had extensive PMH of CAD post-CABG/AICD, AAA repair, chronic anemia, myelodysplastic syndrome, lung cancer after resection, and recurrent GIB. Prior EGDs, colonoscopies, and upper device-assisted enteroscopy showed duodenal ulcer, A-V malformation s/p cauterization, and angioectasia. On admission, Hb was 6.0 g/dL. An endoscopic capsule study showed an ulcerated tumor in the ileum. CT showed no distant metastasis. The lesion was resected successfully and confirmed as a high-grade GIST. The patient was discharged with no further bleeding. Discussion. Early diagnosis for patients with ileal GIST is often challenging. Video capsule endoscopy and double balloon enteroscopy could be useful diagnostic tools. Surgical removal is the first line for a resectable GIST. Imatinib has become the standard therapy. Conclusion. This is a unique case of an ileal GIST in a patient with recurrent GIB which was diagnosed by video capsule. Complicated medical comorbidities often lead to a significant delay in diagnosis. Therefore, we recommend that if GIB does not resolve after appropriate treatments for known causes, the alternative diagnosis for occult GIB must be considered, including malignancy such as GIST.

    To retrospectively compare the diagnostic capabilities of 64-section CT enteroclysis with those of video capsule endoscopy (VCE) to elucidate the cause of obscure gastrointestinal bleeding. Thirty-two patients who had 64-section CT enteroclysis and VCE because of obscure gastrointestinal bleeding were included. Imaging findings were compared with those obtained at double balloon endoscopy, surgery and histopathological analysis, which were used as a standard of reference. Concordant findings were found in 22 patients (22/32; 69%), including normal findings (n = 13), tumours (n = 7), lymphangiectasia (n = 1) and inflammation (n = 1), and discrepancies in 10 patients (10/32; 31%), including ulcers (n = 3), angioectasias (n = 2), tumours (n = 2) and normal findings (n = 3). No statistical difference in the proportions of abnormal findings between 64-section CT enteroclysis (11/32; 34%) and VCE (17/32, 53%) (P = 0.207) was found. However, 64-section CT enteroclysis helped identify tumours not detected at VCE (n = 2) and definitely excluded suspected tumours (n = 3) because of bulges at VCE. Conversely, VCE showed ulcers (n = 3) and angioectasias (n = 2) which were not visible at 64-section CT enteroclysis. Our results suggest that 64-section CT enteroclysis and VCE have similar overall diagnostic yields in patients with obscure gastrointestinal bleeding. However, the two techniques are complementary in this specific population. (orig.)

    Standard external cardiopulmonary resuscitation (SECPR) frequently produces very low perfusion pressures, which are inadequate to achieve restoration of spontaneous circulation (ROSC) and intact survival, particularly when the heart is diseased. Ultra-advanced life support (UALS) techniques may allow support of vital organ systems until either the heart recovers or cardiac repair or replacement is performed. Closed-chest emergency cardiopulmonary bypass (CPB) provides control of blood flow, pressure, composition and temperature, but has so far been applied relatively late. This additional low-flow time may preclude conscious survival. An easy, quick method for vessel access and a small preprimed system that could be taken into the field are needed. Open-chest CPR (OCCPR) is physiologically superior to SECPR, but has also been initiated too late in prior studies. Its application in the field has recently proven feasible. Variations of OCCPR, which deserve clinical trials inside and outside hospitals, include 'minimally invasive direct cardiac massage' (MIDCM), using a pocket-size plunger-like device inserted via a small incision and 'direct mechanical ventricular actuation' (DMVA), using a machine that pneumatically drives a cup placed around the heart. Other novel UALS approaches for further research include the use of an aortic balloon catheter to improve coronary and cerebral blood flow during SECPR, aortic flush techniques and a double-balloon aortic catheter that could allow separate perfusion (and cooling) of the heart, brain and viscera for optimal resuscitation of each. Decision-making, initiation of UALS methods and diagnostic evaluations must be rapid to maximize the potential for ROSC and facilitate decision-making regarding long-term circulatory support versus withdrawal of life support for hopeless cases. Research and development of UALS techniques needs to be coordinated with cerebral resuscitation research.

    To present our experience with the detection of bleeding in the small intestine by means of scintigraphy with in vivo-labelled red blood cells (RBCs) in the period of 1998-2009. A 12-year prospective study was accomplished with 40 patients (23 men, 17 women, aged 12-91, mean 56 years) who had lower gastrointestinal bleeding (obscure-overt bleeding) and underwent scintigraphy with in vivo-labelled RBCs by means of technetium 99m. The scintigraphy was usually performed after other diagnostic tests had failed to locate the bleeding. A total of 26 patients had a positive scintigraphy with in vivo-labelled RBCs and 14 patients had negative scintigraphy. The final diagnosis was confirmed in 20 of 26 patients with a positive scintigraphy by push enteroscopy (6/20), intraoperative enteroscopy (7/20), surgery (4/20), duodenoscopy (1/20), double-balloon enteroscopy (1/20) and X-ray angiography (1/20). The correct location of the bleeding site was identified by RBC scintigraphy in 15 of 20 (75%) patients with the confirmed source. The locations of the bleeding site identified by scintigraphy and enteroscopy (push, intraoperative) and surgical investigations were highly correlated in patients with a positive scintigraphy within the first 3 h. Eleven of the 20 correctly localized studies and none of the incorrectly localized studies were positive in the dynamic phase of imaging. In 5 patients (all erroneously localized), scintigraphy was positive only at a period longer than 18 h. RBC scintigraphy is an effective imaging modality in localizing lower gastrointestinal bleeding in patients for whom other diagnostic tests have failed to locate the bleeding. RBC scintigraphy can be successful in the detection of bleeding sites in the small intestine. Copyright © 2011 S. Karger AG, Basel.

    Unresectable liver metastases of colorectal cancer can be treated with systemic chemotherapy, aiming to limit the disease, extend survival or turn unresectable metastases into resectable ones. Some patients however, suffer from side effects or progression under systemic treatment. For patients with metastasized uveal melanoma there are no standard systemic therapy options. For patients without extrahepatic disease, isolated liver perfusion (IHP) may enable local disease control with limited systemic side effects. Previously, this was performed during open surgery with satisfying results, but morbidity and mortality related to the open procedure, prohibited a widespread application. Therefore, percutaneous hepatic perfusion (PHP) with simultaneous chemofiltration was developed. Besides decreasing morbidity and mortality, this procedure can be repeated, hopefully leading to a higher response rate and improved survival (by local control of disease). During PHP, catheters are placed in the proper hepatic artery, to infuse the chemotherapeutic agent, and in the inferior caval vein to aspirate the chemosaturated blood returning through the hepatic veins. The caval vein catheter is a double balloon catheter that prohibits leakage into the systemic circulation. The blood returning from the hepatic veins is aspirated through the catheter fenestrations and then perfused through an extra-corporeal filtration system. After filtration, the blood is returned to the patient by a third catheter in the right internal jugular vein. During PHP a high dose of melphalan is infused into the liver, which is toxic and would lead to life threatening complications when administered systemically. Because of the significant hemodynamic instability resulting from the combination of caval vein occlusion and chemofiltration, hemodynamic monitoring and hemodynamic support is of paramount importance during this complex procedure.

    Background: Maintenance of mucosal healing is a primary goal when treating Crohn’s disease (CD). Endoscopy is the most precise method for the assessment of mucosal healing, but is considered overly invasive for patients with CD. In contrast, CT enterography (CTE) is less invasive, but little is known about the correlation between mucosal status and CTE parameters. Methods: We recruited CD patients who underwent CTE and double balloon endoscopy (DBE) on the same day at our hospital between 2012 and 2014. CTE parameters evaluated included bowel-wall thickening, mural hyperenhancement, mural stratification (target sign), submucosal fat deposition, mesenteric hypervascularity (comb sign), increased fat density, mesenteric fibrofatty proliferation, enlarged mesenteric lymph nodes, and stenosis/sacculation. Endoscopic findings were evaluated using the Simple Endoscopic Score for Crohn’s Disease (SES-CD). CTE parameters that were predictive of higher values in the SES-CD were extracted statistically. Results: Forty-one patients were recruited, from which 191 intestinal segments were evaluated. Spearman’s rank correlation coefficients showed that the majority of CTE values exhibited mild to moderate correlations with SES-CD values. Notably, multiple ordinal logistic regression analysis demonstrated that CTE findings obtained from the mesenteric area, such as mesenteric hypervascularity (comb sign) and enlarged mesenteric lymph nodes, were more critical predictors of endoscopic mucosal ulceration than those obtained from the bowel wall. Conclusions: This study was the first of its kind to assess correlations between CTE values and SES-CD values. Mesenteric findings of CTE, rather than mural findings, were highly correlated with the endoscopically evaluated severity of ulceration.

    The objective of this article is to provide a comprehensive and update overview of clinical application of CT enterography (CTE) in the evaluation of obscure gastrointestinal bleeding (OGIB). We performed a systematic review of relevant literatures in PubMed, EMBASE and The Cochrane Library and pooled the yield of CTE and the incremental yield (IY) of CTE over an alternate modality. A total of 18 studies (n=660) reported the yield of CTE in evaluating OGIB and the pooled yield was 40% (95% confidence interval (CI): 33–49%). Seven studies (n=279) compared the yield of CTE with capsule endoscopy (CE). The yield for CTE and CE for all findings was 34% and 53%, respectively (IY=−19%, 95% CI=−34% to −4%). When considering the types of identified lesions, the yield was significantly different for vascular and inflammatory lesions but not significantly different for neoplastic or other lesions. Two studies (n=63) compared the yield of CTE with double-balloon enteroscopy (DBE). The yield for CTE and DBE was 38% and 78%, respectively (IY=−40%, 95% CI=−55% to −25%). Three studies (n=49) compared the yield of CTE with digital subtraction angiography. The yield for CTE and digital subtraction angiography was 64% and 60%, respectively (IY=4%, 95% CI=−40% to 47%). CTE is an excellent diagnostic tool in patients with OGIB. It may play a complementary role to CE and can be used as a triage tool prior to DBE in evaluating OGIB.

    Twin arginine translocation (Tat) systems of thylakoid and bacterial membranes transport folded proteins using the proton gradient as the sole energy source. Tat substrates have hydrophobic signal peptides with an essential twin arginine (RR) recognition motif. The multispanning cpTatC plays a central role in Tat operation: It binds the signal peptide, directs translocase assembly, and may facilitate translocation. An in vitro assay with pea (Pisum sativum) chloroplasts was developed to conduct mutagenesis and analysis of cpTatC functions. Ala scanning mutagenesis identified mutants defective in substrate binding and receptor complex assembly. Mutations in the N terminus (S1) and first stromal loop (S2) caused specific defects in signal peptide recognition. Cys matching between substrate and imported cpTatC confirmed that S1 and S2 directly and specifically bind the RR proximal region of the signal peptide. Mutations in four lumen-proximal regions of cpTatC were defective in receptor complex assembly. Copurification and Cys matching analyses suggest that several of the lumen proximal regions may be important for cpTatC-cpTatC interactions. Surprisingly, RR binding domains of adjacent cpTatCs directed strong cpTatC-cpTatC cross-linking. This suggests clustering of binding sites on the multivalent receptor complex and explains the ability of Tat to transport cross-linked multimers. Transport of substrate proteins cross-linked to the signal peptide binding site tentatively identified mutants impaired in the translocation step.

    We performed radionuclide ventriculography before and within 1 week after percutaneous mirtal valvuloplasty (PMV) to evaluate left ventricular (LV) function in 20 patients (2 meals and 17 females, mean age of 38 {+-} 10 years) who were pure mitral stenosis before PMV and less than grade 1 mirtal regurgitation developed after PMV. 9 out of 20 patients had atrial fibrillation and 3 patients developed a small left-to-right shunt (Qp/Qs < 1.5) after PMV. PMV using double-balloon technique resulted in a increase in mitral valve area (0.9 {+-} 0.3 to 2.1 {+-} 0.8cm{sup 2}, {rho} < 0.001) and in rest cardiac output (4.2 {+-} 1.0 to 4.8 {+-} 1.4 L/min, {rho} < 0.005). And also a decrease in mean mitral gradient (16.2 {+-} 7.0 to 5.2 {+-} 3.0 mmHg, {rho} < 0.001) was noted. Comparisons of LV function by supine bicycle exercise radionuclide ventriculography before and after PMV showed no significant changes in rest LV ejection fraction (LVEF, 55.2 {+-} 9.7 to 56.1 {+-} 11.0%, {rho} > 0.05), maximal exercise LVEF (60.9 {+-} 10.3 to 59.3 {+-} 11.1%, {rho} > 0.05), peak ejection rate (2.02 {+-} 0.58 to 2.15 {+-} 0.60 EDV/ses, {rho} > 0.05), and peak filling rate (1.04 {+-} 0.55 to 1.52 {+-} 0.49 EDV/ses, {rho} > 0.05). However, LV end diastolic volume (LVEDV, -29.3 {+-} 19.0 to +3.3 {+-} 32.9%, {rho} < 0.001), stroke volume (SV,-22.0 {+-} 22.0 to +11.2 {+-} 40.0%, {rho} < 0.001), and cardiac output (CO, 64.6 {+-} 54.0 to 100.4 {+-} 69.7%, {rho} < 0.05) with exercise compared to resting values were significantly increased. We conclude that PMV resulted in a significant increase in LVEDV, SV, and CO with exercise, but decreased LV systolic performance and no improvement in diastolic filling.

    Full Text Available El desarrollo de la cápsula endoscópica y la enteroscopia de doble balón ha aumentado las tasas de diagnóstico y tratamiento en la hemorragia digestiva de origen oscuro, en la que las angiodisplasias del intestino delgado son la causa más frecuente. Sin embargo, el 25-40% de los pacientes, no subsidiarios o no respondedores a la terapéutica endoscópica, angiográfica o quirúrgica, pueden tener alto riesgo de resangrado y carecen de tratamiento médico claramente eficaz. La utilidad de la terapia hormonal está cuestionada actualmente, sin olvidar los frecuentes y limitantes efectos secundarios. El octreótido suele ser eficaz en el control de la hemorragia pero no parece la terapia de mantenimiento más óptima. Los beta-bloqueantes no selectivos, de igual manera que en la profilaxis de la hemorragia por hipertensión portal, pueden ser útiles en combinación con otros fármacos. Recientemente, el octreotido LAR, una formulación de liberación retardada que se administra una vez al mes por vía intramuscular, y la talidomida oral, un potente inhibidor de la angiogénesis, han demostrado su eficacia y seguridad a largo plazo en casos graves aislados.The development of capsule endoscopy and double-balloon enteroscopy has increased diagnostic and therapeutic rates in obscure gastrointestinal hemorrhage, where angiodysplasia of the small bowel is the most frequent cause. Nevertheless, almost 25-40% of patients who are not candidates or do not respond to endoscopic, angiographic, or surgical management may be at high risk of rebleeding, and therefore lack a clearly effective medical therapy. The utility of hormonal therapy remains unclear and is burdened by adverse effects. Subcutaneous octreotide usually controls bleeding but does not seem adequate for mainteinance therapy. Non-selective beta-blockers alone or in combination with other treatments, as in the prophylaxis of portal hypertension variceal bleeding, may be helpful. Recently

    Full Text Available A anemia por deficiência de ferro (ADF ou a deficiência de ferro (DF isolada são comuns em crianças e mulheres pré-menopausa. Entretanto, em adultos do sexo masculino e mulheres pós-menopausa, essa condição se associa frequentemente a perdas sanguíneas gastrointestinais ou mal absorção. A prevalência das lesões gastrointestinais torna essencial o exame do aparelho digestório superior e inferior através da endoscopia. Investigações complementares devem ser realizadas se os procedimentos endoscópicos não evidenciarem sangramento em situações clínicas, tais como a necessidade de múltiplas hemotransfusões, a ausência de sangramento visível à endoscopia digestiva alta e colonoscopia e a falta de resposta à reposição de ferro.Esses casos devem ser direcionados para investigação do intestino delgado com métodos radiológicos ou, mais recentemente, com a cápsula endoscópica e da enteroscopia com duplo balão. A cintigrafia com hemácias marcadas e a angiografia têm papel restrito, sendo utilizadas apenas no sangramento aberto. O tratamento varia de acordo com a etiologia, a intensidade da perda sanguínea e da deficiência de ferro.Iron deficiency anaemia and isolated iron deficiency are common in children and pre-menopausal women. However, in male adults and post-menopausal women this condition is most frequently caused by gastrointestinal blood loss or malabsorption. The prevalence of gastrointestinal lesions makes the examination by endoscopy of both upper and lower gastrointestinal tracts essential. Further investigations, when the initial exams are negative, are only warranted in cases of multiple transfusions, visible blood loss or lack of response to oral iron supplementation. In these cases examinations should be focused on the small bowel by radiological methods or more recently using capsule endoscopy and double balloon enteroscopy. Nuclear medicine and angiography have a limited role to play in this

    Objective: To assess the technical feasibility and effectiveness of fluoroscopically-guided transnasal insertion of ileus tube for intestinal decompression in the treatment of inoperable malignant bowel obstruction. Methods: A total of 211 patients with inoperable malignant bowel obstruction were enrolled in this study. The median KPS scale was 40 (ranged from 20 to 60). Under fluoroscopic guidance, transnasal insertion of ileus tube by using conventional technique or guidewire-catheter exchange technique was performed in all patients. The technical success rate, the clinical effective rate, the curative rate and adverse reactions as well as complications were documented. The correlation among the obstructive sites, obstruction causes and therapeutic effectiveness was analyzed. The ileus tube used in this study was a four-cavity and double-balloon catheter with a diameter of 16 F/18 f, which is produced by Cliny Company. Results: Transnasal drainage tube was successfully inserted into the proximal jejunum in all 211 patients with malignant bowel obstruction, and the total technical success rate was 100%. The initial technical success rate of the traditional technique and the catheter-guidewire exchange method was 85.5% (65/76) and 100% (135/135) respectively, the difference between the two was significant (P<0.05). After 24 hours, the clinical remission rate in the patients with high-level intestinal obstruction, lower-level intestinal obstruction and colorectal obstruction was 95.8% (46/48), 92.9% (117/126) and 83.8% (31/37), respectively. A follow-up of 4-245 days (mean 138 days) was conducted, and the total clinical cure rate was 27.5% (58/211). The clinical cure rate in small intestine obstruction and colorectal obstruction caused by primary tumor or recurrence was 12.7% (20/157) and 59.5% (22/37), respectively (P<0.05). The adverse reactions and complications included uncomfortable pharynx feeling or pain (99.1%, 199/221), the tube obstruction (23.2%, 49

    Full Text Available Background: recent advances in endoscopy have enabled us to explore the small intestine more efficiently, both with capsule endoscopy and double-balloon enteroscopy. However, these methods are not available in all hospitals. Therefore, when capsule endoscopy reveals proximal jejunal lesions, a possible alternative for treatment could involve push enteroscopy combined with colonoscopy. Lesions can thus be marked for subsequent monitoring. Objectives: to describe the efficacy of pediatric colonoscopy for diagnosis, the marking of the area explored, and therapeutic options. Material and methods: between October 2007 and September 2008 a total of 21 enteroscopies were performed using a pediatric colonoscope. Nine of these were used to take jejunal biopsy samples due to suspected disease of the mucosa. In 10 of the remaining 12, capsule endoscopy revealed lesions (vascular malformations or jejunal bleeding, and in 2 intestinal transit time was analyzed due to suspected jejunal stenosis. We used a PENTAX EC-3470-LK pediatric colonoscope, whose 11.6-mm sectional diameter and 3.8-mm working channel make it possible to administer all the usual endoscopic treatments. Results: therapeutic endoscopy was performed on 7 men and 5 women (mean age 63.3 years. Jejunal lesions were observed in 10 cases (5 cases of angiodysplasia, 2 cases of jejunal stenosis, 1 case of nonmalignant thickened jejunal folds, 1 eroded submucosal tumor, and 1 case of duodenal and jejunal varices. The most distal area was marked with India ink (2, hemoclips (4, or both to help locate the lesions using simple abdominal radiography or capsule endoscopy. Conclusions: jejunal enteroscopy enabled a firm diagnosis to be made in most of the patients studied. We were able to treat 58% of patients and mark the areas explored for subsequent follow-up. With hemoclips we were able to locate the most distal point explored using simple abdominal radiography.Introducción: los recientes avances en
