Abstract
Diaphragm disease is a rare cause of small bowel obstruction, caused by circular fibrotic membranes resulting in a narrowed intestinal lumen. It is associated with prolonged non-steroidal anti-inflammatory drug use, and often requires surgical resection. We report the case of a man in his 50s presenting with recurrent anaemia and intermittent small bowel obstruction. Exploratory laparoscopy identified three distinct areas of congested, thickened and narrowed ileum. Symptoms resolved following small bowel resection. Histological examination found elongated mucosal folds with ulceration and submucosal fibrosis consistent with diaphragm disease. Common radiological findings include small bowel strictures and thickening, mucosal hyperenhancement, and small bowel dilatation. In this case, on retrospective review of the initial CT scan, it is possible to appreciate circumferential mural thickening correlating with the histological findings. This case highlights the importance of rigorous examination of CT imaging and the utility of exploratory laparoscopy in diagnosing diaphragm disease.

Abstract
Small bowel diaphragm disease is a rare condition usually associated with the prolonged use of non-steroidal anti-inflammatory drugs (NSAID) and that can be mistaken and treated as other pathologies. We describe a case of a 64-year-old man with a prolonged course of pain and subacute bowel obstructions, without any history of NSAID usage, found to have a multiple diaphragmatic stricture in the small bowel.

Abstract
Small bowel obstruction (SBO) is a common illness encountered by general surgeons. However, obstruction caused by diaphragm disease induced by non-steroidal anti-inflammatory drug (NSAID) is exceedingly rare. The diagnosis is challenging as the signs and symptoms are neither sensitive nor specific. We report the case of a 59-year-old male who presented with SBO secondary to this uncommon condition. We hope to raise awareness of this unusual entity.

Abstract
Non-steroidal anti-inflammatory drug (NSAIDs) induced enteropathy represents an important complication of one of the most commonly used drugs worldwide. Due to previous diagnostics difficulties the real prevalence of this disease was underestimated for a long time. The pathogenesis of NSAID-enteropathy is more multifactorial and complex than formerly assumed but has still not been fully uncovered. A combination of the local and systemic effect plays an important role in pathogenesis. Thanks to novel enteroscopy methods (wireless capsule endoscopy, double balloon enteroscopy), small bowel lesions are described in a substantial section of NSAID users although most are clinically asymptomatic. The other non-invasive tests (small bowel permeability, faecal calprotectin, scintigraphy using faecal excretion of 111-indium-labelled leukocytes etc.) proposed for diagnostics are not generally used in clinical practice, mainly because of their non-specificity. Despite intensive research into possible treatment, the main measure for patients with NSAID-enteropathy is still withdrawal of NSAIDs. Double balloon enteroscopy plays an important role in the treatment of complications (bleeding, strictures).

Abstract
Background. To demonstrate the clinical features, diagnosis, and treatment of nonsteroidal anti-inflammatory drug- (NSAID-) induced diaphragm disease (DD). Methods. A literature search between January 1973 and August 2015 was undertaken. The clinical data of patients with NSAID-induced DD were recorded and analyzed. Results. 159 patients were included. The ratio of male to female was 1 : 2.3; the mean age was 65 ± 11 years. The most common clinical manifestations were gastrointestinal bleeding and obstruction. 121 (84%) patients took traditional NSAIDs. The durations of NSAIDs use ranged from 2 to 300 months. A majority (59.7%) of DD were seen in the small bowel, were seen secondly in the colon (30.2%), and were mainly located in the ileum (57.9%) and right colon (91.7%), respectively. 80% of patients had multiple diaphragms. 41.5% of small bowel DD were diagnosed preoperatively by capsule endoscopy and/or double-balloon enteroscopy, 52.1% at laparotomy. Nearly 75% of patients underwent surgery, endoscopic balloon dilation was performed in 22 patients, and NSAIDs were withdrawn in 53 patients. Conclusions. NSAID-induced DD is relatively rare. The small bowel is most commonly involved. Preoperative diagnosis of small bowel DD is relatively difficult. Discontinuation of the NSAIDs is recommended, surgical resection is the main treatment presently, and endoscopic balloon dilation should be considered as an alternative therapy.

Abstract
CT and MR enterography and capsule endoscopy are increasingly used as routine diagnostic tests for patients with potential small bowel disorders and obscure gastrointestinal bleeding. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used drugs that disrupt prostaglandin synthesis and result in a variety of localized complications within the small bowel ranging from ulcer formation to characteristic circumferential strictures, or diaphragms. NSAID enteropathy encompasses this spectrum of acute and chronic inflammatory sequelae, and is associated with typical findings at capsule endoscopy and surgery. Herein we review the typical clinical presentation of NSAID enteropathy, in addition to its endoscopic appearances, focusing on imaging findings at cross-sectional enterography. Multiple, short-segment strictures are the hallmarks of imaging diagnosis. Strictures may have minimal hyperenhancement or wall thickening, but these findings are typically symmetric and circumferential with respect to the bowel lumen. Multifocal Crohn's strictures, and occasionally radiation-induced strictures or adhesions, will mimic NSAID diaphragms. Multi-phase or multi-sequence imaging at CT and MR enterography increase diagnostic confidence in stricture presence. Strategies for subsequent workup and therapy after enterography are also discussed. Given the frequent use of NSAIDs and typical appearance of these strictures, knowledge of characteristic imaging findings can be particularly useful when evaluating patients with anemia and recurrent small bowel obstruction.

Abstract
Background. The purpose of study was to evaluate the diagnostic yield of capsule endoscopy for NSAID-induced enteropathy and clinical, laboratory, and endoscopic characteristics of disease in patients with rheumatoid arthritis. Methods. 37 rheumatoid arthritis patients (30 women; mean age 55) treated with NSAIDs (>1 month), presented with anaemia and/or positive faecal occult blood testing, entered the study and underwent capsule endoscopy (EndoCapsule; Olympus), laboratory tests, and filled in questionnaires. Results. The prevalence of NSAID-induced enteropathy diagnosed by capsule endoscopy was 68% (25/37), classified as mild (red spots or erosions) in 18 (49%), moderate (10–20 erosions) in 4 (11%), and severe enteropathy (>20 erosions or ulcers) in 3 (8%) patients. We did not find statistically significant relationship between the enteropathy and gender, age, haemoglobin, leukocytes, albumin and CRP, or dyspepsia. The difference between subgroups of NSAIDs according to the COX specificity was not statistically significant. Conclusions. Capsule endoscopy is a highly accurate noninvasive method for evaluation of NSAID-induced enteropathy. It was revealed in a substantial section of the patients with rheumatoid arthritis and occult gastrointestinal bleeding, mostly classified as mild damage. No simple clinical or laboratory markers of the presence or severity of NSAID-induced enteropathy were recognised. This trial is registered with DRKS00004940.

Abstract
BACKGROUND Evaluating small bowel patency is recommended for capsule endoscopy in patients suspected of nonsteroidal anti-inflammatory drug-induced (NSAID) enteropathy. AIMS The aim of this investigation was to examine whether radiography is a candidate of patency tool in NSAID enteropathy. METHODS We reviewed double-contrast barium enteroclysis in 21 patients with NSAID enteropathy diagnosed either by capsule endoscopy or balloon-assisted endoscopy. The endoscopic findings were classified into circular ulcers, linear ulcers and small mucosal defects. The radiographic signs of the corresponding endoscopic findings were retrieved and the depiction rate was calculated. RESULTS Of the 21 patients, endoscopy detected circular ulcers, linear ulcers, and small ulcers in 12, 3 and 12 patients, respectively. Small bowel radiography depicted circular narrowing as pseudo-folds in 10 patients (83%) and linear ulcers as eccentric rigidity in 2 patients (67%). However, radiography was able to depict small mucosal defects in only 3 patients (17%). Two of 5 patients with pseudo-folds experienced retention of the capsule. CONCLUSION "Pseudo-folds" is a sign corresponding to circular ulcer in NSAID enteropathy, which may be predictive of capsule retention.

Abstract
AIM: To summarize clinical, endoscopic, radiologic and pathologic features of special diaphragm-like strictures found in small bowel, with no patient use of non-steroidal anti-inflammatory drugs (NSAIDs).
METHODS: From January 2000 to December 2009, 5 cases (2 men and 3 women, with a mean age of 41.6 years) were diagnosed as having diaphragm-like strictures of small bowel on imaging, operation and pathology. All the patients denied the use of NSAIDs. The clinical, endoscopic, radiologic and pathologic findings in these 5 patients were retrospectively reviewed from the hospital database. Images of capsule endoscopy (CE) and small bowel follow-through (SBFT) obtained in 3 and 3 patients, respectively, and images of double-balloon enteroscopy and computed tomography enterography (CTE) obtained in all 5 patients were available for review.
RESULTS: All patients presented with long-term (2-16 years) symptoms of gastrointestinal bleeding and varying degrees of anemia. There was only one stricture in four cases and three lesions in one case, and all the lesions were located in the middle or distal segment of ileum. Circumferential stricture was shown in the small bowel in three cases in the CE image, but the capsule was retained in the small bowel of 2 patients. Routine abdomen computed tomography scan showed no other abnormal results except gallstones in one patient. The lesions were shown as circumferential strictures accompanied by dilated small bowel loops in the small bowel on the images of CTE (in all 5 cases), SBFT (in 2 cases) and double-balloon enteroscopy (in all cases). On microscopy, a chronic inflammatory infiltrate and circumferential diaphragm were found in all lesions.
CONCLUSION: Diaphragm-like strictures of small bowel might be a special consequence of unclear damaging insults to the intestine, having similar clinical, endoscopic, radiologic and pathologic features.

Abstract
As the use of drugs such as nonsteroidal anti-inflammatory drugs (NSAIDs) increases, so too do gastrointestinal ulcers, bleeding, perforation and obstruction. Diaphragm disease of the small intestine is formed by submucosal fibrosis and destruction of lamina muscularis due to chronic ulceration, which corresponds to the most severe stage of NSAID enteropathy. It may lead to stricture of the small intestine. If such ulcerations and strictures in the small intestine are multiple, differential diagnosis is between diaphragm disease and cryptogenic multifocal ulcerous stenosing enteritis (CMUSE), because the gross findings of diaphragm disease are similar to those of CMUSE. We report a rare case of diaphragm disease caused by NSAID. It has been finally confirmed by capsule endoscopy and the origin of chronic obscure gastrointestinal bleeding was found to be multiple ulcers and strictures in the small intestine. After operation, we diagnosed the patient with diaphragm disease rather than CMUSE.

Abstract
The injurious effect of nonsteroidal anti-inflammatory drugs (NSAIDs) in the small intestine was not appreciated until the widespread use of capsule endoscopy. Animal studies found that NSAID-induced small intestinal injury depends on the ability of these drugs to be secreted into the bile. Because the individual toxicity of amphiphilic bile acids and NSAIDs directly correlates with their interactions with phospholipid membranes, we propose that the presence of both NSAIDs and bile acids alters their individual physicochemical properties and enhances the disruptive effect on cell membranes and overall cytotoxicity. We utilized in vitro gastric AGS and intestinal IEC-6 cells and found that combinations of bile acid, deoxycholic acid (DC), taurodeoxycholic acid, glycodeoxycholic acid, and the NSAID indomethacin (Indo) significantly increased cell plasma membrane permeability and became more cytotoxic than these agents alone. We confirmed this finding by measuring liposome permeability and intramembrane packing in synthetic model membranes exposed to DC, Indo, or combinations of both agents. By measuring physicochemical parameters, such as fluorescence resonance energy transfer and membrane surface charge, we found that Indo associated with phosphatidylcholine and promoted the molecular aggregation of DC and potential formation of larger and isolated bile acid complexes within either biomembranes or bile acid-lipid mixed micelles, which leads to membrane disruption. In this study, we demonstrated increased cytotoxicity of combinations of bile acid and NSAID and provided a molecular mechanism for the observed toxicity. This mechanism potentially contributes to the NSAID-induced injury in the small bowel.

Abstract
PURPOSE The goal of this study was to compare magnetic resonance enterography (MRE) and video capsule endoscopy (VCE) in suspected small bowel disease. MATERIALS AND METHODS Nineteen patients with suspected small bowel disease participated in a prospective clinical comparison of MRE versus VCE. Both methods were evaluated separately and in conjunction with respect to a combined diagnostic endpoint based on clinical, laboratory, surgical, and histopathological findings. The Fisher's exact and j tests were used in comparing MRE and VCE. RESULTS Small bowel pathologies were found in 15 out of 19 patients: Crohn's disease (n= 5), lymphoma (n= 4), lymphangioma (n= 1), adenocarcinoma (n= 1), postradiation enteropathy (n= 1), NSAID-induced enteropathy (n =1), angiodysplasia (n= 1), and small bowel adhesions (n= 1). VCE and MRE separately and in conjunction showed sensitivities of 92.9, 71.4, and 100% and specificities of 80, 60, and 80% (kappa= 0.73 vs. kappa = 0.29; P= 0.31/kappa = 0.85), respectively. In four patients, VCE depicted mucosal pathologies missed by MRE. MRE revealed 19 extraenteric findings in 11 patients as well as small bowel adhesions not detected on VCE (n= 1). CONCLUSION VCE can readily depict and characterize subtle mucosal lesions missed at MRE, whereas MRE yields additional mural, perienteric, and extraenteric information. Thus, VCE and MRE appear to be complementary methods which, when used in conjunction, may better characterize suspected small bowel disease.

Abstract
BACKGROUND Double-balloon enteroscopy is a new technique that allows endoscopic therapy throughout the entire length of the small bowel. Diaphragm disease, characterized by thin septa that narrow the small-bowel lumen, is traditionally treated surgically by segmental resection. OBJECTIVE To report successful endoscopic treatment of diaphragm disease by double-balloon enteroscopy. PATIENTS Three patients. DESIGN Case report. INTERVENTIONS Double-balloon enteroscopy and stricture balloon dilation. RESULTS We report, for the first time, 3 cases in which diaphragm strictures were successfully treated during double-balloon enteroscopy. In 2 cases, a retained capsule endoscope was removed by the retrograde approach after stricture dilation. LIMITATIONS Small number of patients and brief length of patient follow up. CONCLUSION Double-balloon enteroscopy may be used to treat patients with diaphragm disease, thus avoiding potentially complicated surgery.

Abstract
Diaphragm-like stricture of the small bowel is an infrequent complication of the treatment of patients with nonsteroidal anti-inflammatory drugs (NSAIDs) and is part of the spectrum of diseases associated with NSAIDs injury. We report a patient with this condition who had used various forms of NSAIDs for over 20 years. Patient presented with abdominal pain and indigestion. Plain abdominal film revealed small bowel obstruction. Surgical resection of jejunum and proximal part of ileum identified dilated thickened hyperemic mucosa alternating with areas of small bowel fibrotic constriction. The mucosal surface showed multiple pink-tan mucosal folds (circumferential ridges) with focal hemorrhage and edema. Our findings support the local stimulation and damage and reparative process seen with NSAIDs use. A high degree of suspicion and awareness of diaphragm disease is necessary in those patients.

Abstract
Capsule endoscopy is a revolutionary new diagnostic tool for the detection of small bowel disease. As the name implies, capsule endoscopy makes use of a swallowable video capsule; as such, it is the only technique that allows noninvasive endoscopic examination of the entire small bowel without sedation. Obscure gastrointestinal bleeding is the most common indication for capsule endoscopy, which commonly depicts arteriovenous malformations, small bowel tumors, and ulcers missed at standard endoscopy and imaging examinations. However, capsule endoscopy is not optimal for the localization of small bowel lesions. In addition, lesions can be missed due to poor bowel preparation, rapid or delayed small bowel transit, or orientation of the camera away from a lesion. Computed tomography and barium examinations are useful for detecting these missed lesions and for localizing lesions detected at capsule endoscopy. Other limitations of capsule endoscopy are the inability to treat lesions and its limited use in patients with small bowel strictures or obstruction. Nevertheless, this new technique is easy to perform, is well tolerated by patients, and, for the first time, allows noninvasive endoscopic evaluation of the entire small bowel.

Abstract
Diaphragm disease of the small intestine is part of the spectrum of diseases associated with injury to the gastrointestinal tract induced by nonsteroidal anti-inflammatory drugs. Standard endoscopy or contrast studies of the small intestine rarely identify these lesions. The diagnosis usually is established at the time of surgery. We report the case of a 72-year-old woman with obscure gastrointestinal bleeding and intermittent obstruction of the small intestine who had had multiple hospitalizations and extensive testing. The patient had been treated with nonsteroidal anti-inflammatory drugs for osteoarthritis. A radiograph of the small intestine with barium contrast revealed no abnormalities, so capsule endoscopy was performed. Capsule endoscopy showed multiple small intestinal strictures beyond which the capsule could not pass. After the patient experienced continued symptoms suggestive of intermittent partial obstruction of the small intestine, computed tomography showed the capsule within a dilated loop of intestine adjacent to a stricture. After 9 days of conservative medical therapy and worsening symptoms, the patient required an exploratory laparotomy. The capsule was located in a 12-cm segment of intestine with 4 diaphragm-like lesions. Pathologic study found submucosal lesions with features identical to those of neuromuscular and vascular hamartoma (eg, mature, reactive tissue elements of smooth muscle, dense fibrous tissue, and nerve tissue bundles with scattered ganglion cells and vessels). No manifestations of Crohn disease were evident. This case represents the first diagnosis with capsule endoscopy of diaphragm disease of the small intestine with pathologic features of neuromuscular and vascular hamartoma.

Abstract
NSAID-induced intestinal toxicity is more common than previously recognized and may have clinically significant sequelae, especially in elderly arthritic patients. Increased awareness of the potential intestinal complications associated with prostaglandin inhibition is required for early recognition and appropriate management. An increase in the level of suspicion by physicians may lead to earlier diagnosis and subsequent discontinuation of the offending NSAID; this is important in that discontinuation of the offending agent may be preferable to multiple endoscopic radiologic and surgical procedures in the patient with obscure blood loss and anemia. Appropriate diagnosis in selected patients may prevent the increased morbidity and mortality associated with small intestinal surgery. The emergence of selective COX-2 inhibitors likely will bring this issue to the forefront because it will become increasingly important to determine the effects of these agents on the small intestine and colon, in addition to their effects on the gastroduodenal mucosa. The new generation of selective COX-2 inhibitors may offer a potential therapeutic advantage over the nonselective NSAIDs with respect to their intestinal toxicity. Well-designed safety trials that have intestinal injury as a predefined end point will provide important information as to the overall gastrointestinal safety of these compounds. These agents must be evaluated with respect to their overall safety profile and not just by their gastrointestinal safety. Nevertheless, these agents are continuing to provide new directions for exciting basic and clinical scientific investigation.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) may adversely affect the colon, either by causing a non-specific colitis or by exacerbating a preexisting colonic disease. Patients with NSAID-induced colitis present with bloody diarrhoea, weight loss, iron deficiency anaemia and sometimes abdominal pain. Colonoscopy may be normal or may show inflammation, ulceration or diaphragm-like stricture. Histology often concludes to non-specific colitis. NSAIDs may cause perforation or bleeding of colonic diverticula, may cause relapse to inflammatory bowel disease and may exacerbate bleeding of colonic angiodysplasia. Pathogenesis of NSAID-induced colitis is still controversial. Local and/or systemic effects of NSAIDs on mucosal cells might lead to an increased intestinal permeability, which is a prerequisite for colitis. Treatment of NSAID-induced colitis should be to discontinue the drug, or at least, to reduce the dose as much as possible. Sulphasalazine and Metronidazole have been successfully used in few studies. Surgery is often indicated in case of life threatening complications or untractable symptoms.

Abstract
There are clinical data suggesting that the intubation method (enteroclysis) is the most accurate form of examining the small bowel. The diagnostic accuracy of small bowel enema is generally found superior to that of the tubeless method. Despite the growing interest in small bowel enema this procedure has not yet become the prevailing method in Western countries. However, due to further developments in sonde or push enteroscopy in which 300 cm of the small bowel can be visualized, it is of utmost importance to perform state of the art radiological small bowel enteroclysis investigation, otherwise the bright lights from enteroscopy will rapidly illuminate the dark corners of the small intestine, leaving no place for radiology.
