Colonoscopy revealed edematous mucosa,and histopathological examination was compatible with collagenous colitis. Protein leakage from the colon,particularly in the ascending portion,was identified on 99mTc-human serum albumin scintigraphy. Collagenous colitis associated with protein-losing enteropathy (PLE) without small bowel disease was diagnosed. Prednisolone treatment ameliorated diarrhea and hypoproteinemia. Collagenous colitis should be included in the differential diagnosis of chronic diarrhea with hypoproteinemia for appropriate management.展开更多

It may lead to hypoproteinemia and clinically present as protein deficiency edema, ascites, pleural or pericardial effusion and/or malnutrition. In most cases the site of protein loss is the small intestine. Here we present an unusual case of severe PLE in a 55-year old female with a one-year history of recurrent diarrhea, crampy abdominal pain, and peripheral edema. Endoscopy and MRI showed a diffuse inflammatory thickening of the sigmoid colon and the rectum. Surgical resection of the involved colon was performed and the symptoms were significantly resolved. The final histologic evaluation confirmed a diagnosis of a pseudomembranous colitis with cap polyposis-like features. Such a cause of PLE has never been described before.展开更多

This entity is being increasing...Portal hypertensive enteropathy(PHE) is a condition that describes the pathologic changes and mucosal abnormalities observed in the small intestine of patients with portal hypertension. This entity is being increasingly recognized and better understood over the past decade due to increased accessibility of the small intestine made possible by the introduction of video capsule endoscopy and deep enteroscopy. Though challenged by its diverse endoscopic appearance, multiple scoring systems have been proposed to classify the endoscopic presentationand grade its severity. Endoscopic findings can be broadly categorized into vascular and non-vascular lesions with many subtypes of both categories. Clinical manifestations of PHE can range from asymptomatic incidental findings to fatal gastrointestinal hemorrhage. Classic endoscopic findings in the setting of portal hypertension may lead to a prompt diagnosis. Occasionally histopathology and cross sectional imaging like computed tomography or magnetic resonance imaging may be helpful in establishing a diagnosis. Management of overt bleeding requires multidisciplinary approach involving hepatologists, endoscopists, surgeons, and interventional radiologists. Adequate resuscitation, reduction of portal pressure, and endoscopic therapeutic intervention remain the main principles of the initial treatment. This article reviews the existing evidence on PHE with emphasis on its classification, diagnosis, clinical manifestations, endoscopic appearance, pathological findings, and clinical management. A new schematic management of ectopic variceal bleed is also proposed.展开更多

Studies published in the biomedical literature during the past four decades and cited in PubMed, as well as clinical and laboratory data from our own research program are reviewed. The risk of injury to normal tissues limits the cancer cure rates that can be achieved with radiation therapy. During treatment of abdominal and pelvic tumors, the intestine is frequently a major close-limiting factor. Microvascular injury is a prominent feature of both early (inflammatory), as well as delayed (fibroproliferative) radiation injuries in the intestine and in many other normal tissues. Evidence from our and other laboratories suggests that endothelial dysfunction, notably a deficiency of endothelial thrombomodulin, plays a key role in the pathogenesis of these radiation responses. Deficient levels of thrombomodulin cause loss of vascular thromboresistance, excessive activation of cellular thrombin receptors by thrombin, and insufficient activation of protein C, a plasma protein with anticoagulant, anti-inflammatory, and cytoprotective properties. These changes are presumed to be critically involved in many aspects of early intestinal radiation toxicity and may sustain the fibroproliferative processes that lead to delayed intestinal dysfunction, fibrosis, and clinical complications. In conclusion, injury of vascular endothelium is important in the pathogenesis of the intestinal radiation response. Endothelial-oriented interventions are appealing strategies to prevent or treat normal tissue toxicity associated with radiation treatment of cancer.展开更多

We report the novel case of a patient who, years after liver transplantation developed a functional blind loop in an incisional hernia, which manifested as oedema and hypoproteinaemia secondary to protein losing enteropathy. After numerous investigations, the diagnosis was made by flurodeoxyglucose positron emmision tomography (FDG-PET) imaging. Surgical repair of the incisional hernia was followed several months later by resolution of the protein loss, and confirmed at a post operative FDG-PET scan at one year.展开更多

METHODS: Fifty-nine patients were prospectively enrolled by twelve surgical departments. Primary malignant disease,radiation therapy and surgical management were recorded at inclusion. The cause of death or persistence of symptoms was examined in public death records or by interview of survivors. RESULTS: Thirty-nine patients had received radiation therapy for gynaecological cancers,twelve for urological cancers,four for gastrointestinal cancers and four for other malignancies. Forty-five patients (76%) required surgical intervention. Complications occurred in 11 (25%) operated patients. Forty-seven patients had died at the time of follow-up,seven (12%) died as a direct result of radiation enteropathy,while radiation enteropathy contributed to death in an additional seven patients. Four of the twelve surviving patients suffered from chronic debilitating symptoms of radiation enteropathy,while three had moderate symptoms. CONCLUSION: Patients with severe delayed radiation enteropathy have a high risk of persistence of symptoms after surgery. At least one in ten patients dies from radiation-induced bowel injury.展开更多

文摘A 76-year-old woman with a 5-mo history of recurrent diarrhea and generalized edema was admitted to our hospital. Colonoscopy revealed edematous mucosa,and histopathological examination was compatible with collagenous colitis. Protein leakage from the colon,particularly in the ascending portion,was identified on 99mTc-human serum albumin scintigraphy. Collagenous colitis associated with protein-losing enteropathy (PLE) without small bowel disease was diagnosed. Prednisolone treatment ameliorated diarrhea and hypoproteinemia. Collagenous colitis should be included in the differential diagnosis of chronic diarrhea with hypoproteinemia for appropriate management.
文摘BACKGROUND The incidence of internal hernias has recently increased in concordance with the popularization of laparoscopic surgery.Of particular concern are internal hernias occurring in Petersen's space,a space that is surgically created after treatment for gastric cancer and obesity.These hernias cause devastating sequelae,such as massive intestinal necrosis,fatal Roux limb necrosis,and superior mesenteric vein thrombus.In addition,protein-losing enteropathy(PLE)is a rare syndrome involving gastrointestinal protein loss,although its relationship with internal Petersen’s hernias remains unknown.CASE SUMMARY A 75-year-old man with a history of laparotomy for early gastric cancer developed Petersen's hernia 1 year and 5 mo after surgery.He was successfully treated by reducing the incarcerated small intestine and closure of Petersen’s defect without resection of the small intestine.Approximately 3 mo after his surgery for Petersen’s hernia,he developed bilateral leg edema and hypoalbuminemia.He was diagnosed with PLE with an alpha-1 antitrypsin clearance of 733 mL/24 h.Double-balloon enteroscopy revealed extensive jejunal ulceration as the etiology,and it facilitated minimum bowel resection.Pathological analysis showed extensive jejunal ulceration and collagen hyperplasia with nonspecific inflammation of all layers without lymphangiectasia,lymphoma,or vascular abnormalities.His postoperative course was unremarkable,and his bilateral leg edema and hypoalbuminemia improved after 1 mo.There was no relapse over the 5-year follow-up period.CONCLUSION PLE and extensive jejunal ulceration may occur after Petersen's hernia.Doubleballoon enteroscopy helps identify and resect these lesions.

文摘BACKGROUND Eosinophilic gastrointestinal disease(EGID)is a disorder characterized by infiltration of eosinophils causing mucosal damage and dysfunction of the gastrointestinal tract.The endoscopic findings of eosinophilic enteritis(EoN),an EGID variant,are nonspecific and occasionally difficult to diagnose.In contrast,chronic enteropathy associated with SLCO2A1(CEAS)is a chronic persistent small intestinal disorder characterized by endoscopic findings such as multiple oblique and circular ulcers.CASE SUMMARY We report the case of a 10-year-old boy who had suffered abdominal pain and fatigue for the preceding 6 mo.He was referred to our institute for investigation of suspected gastrointestinal bleeding because of severe anemia with hypoproteinemia and positive fecal human hemoglobin.The upper and lower gastrointestinal endoscopic findings were normal;however,double-balloon small bowel endoscopy showed multiple oblique and circular ulcers with discrete margins and mild constriction of the intestinal lumen in the ileum.The findings were highly consistent with CEAS,but urine prostaglandin metabolites were within normal limits,and no previously reported mutations in the SLCO2A1 gene were identified.Histological evaluation demonstrated moderate to severe eosinophilic infiltration localized to the small intestine suggesting a diagnosis of EoN.Clinical remission was maintained with montelukast and a partial elemental diet,but emergent surgery for bowel obstruction due to small intestinal stenosis was performed two years after the initial treatment.CONCLUSION EoN should be considered in the differential diagnosis of CEAS-like small intestinal ulcerative lesions and normal urinary prostaglandin metabolite levels.
文摘BACKGROUND While primary intestinal lymphangiectasia(PIL)is considered a rare condition,there have been several reported cases in adults.Nevertheless,the absence of clear guidance from diagnosis to treatment and prognosis poses challenges for both physicians and patients.AIM To enhance understanding by investigating clinical presentation,diagnosis,treatment,complications,and prognoses in adult PIL cases.METHODS We enrolled adult patients diagnosed with PIL between March 2016 and September 2021.The primary outcome involved examining the diagnosis and treatment process of these patients.The secondary outcomes included identifying complications(infections,thromboembolism)and assessing prognoses(frequency of hospitalization and mortality)during the follow-up period.RESULTS Among the 12 included patients,peripheral edema(100%)and diarrhea(75%)were the main presenting complaints.Laboratory tests showed that all the pati-ents exhibited symptoms of hypoalbuminemia and hypogammaglobulinemia.Radiologically,the predominant findings were edema of the small intestine(67%)and ascites(58%).The typical endoscopic finding with a snowflake appearance was observed in 75%of patients.Among the 12 patients,two responded positive-ly to octreotide and sirolimus,and eight who could undergo maintenance therapy discontinued subsequently.Complications due to PIL led to infection in half of the patients,thromboembolism in three patients,and one death.CONCLUSION PIL can be diagnosed in adults across various age groups,with different severity and treatment responses among patients,leading to diverse complications and prognoses.Consequently,tailored treatments will be necessary.We anticipate that our findings will contribute to the management of PIL,an etiology of protein-losing enteropathy.

文摘Portal hypertensive enteropathy(PHE) is a condition that describes the pathologic changes and mucosal abnormalities observed in the small intestine of patients with portal hypertension. This entity is being increasingly recognized and better understood over the past decade due to increased accessibility of the small intestine made possible by the introduction of video capsule endoscopy and deep enteroscopy. Though challenged by its diverse endoscopic appearance, multiple scoring systems have been proposed to classify the endoscopic presentationand grade its severity. Endoscopic findings can be broadly categorized into vascular and non-vascular lesions with many subtypes of both categories. Clinical manifestations of PHE can range from asymptomatic incidental findings to fatal gastrointestinal hemorrhage. Classic endoscopic findings in the setting of portal hypertension may lead to a prompt diagnosis. Occasionally histopathology and cross sectional imaging like computed tomography or magnetic resonance imaging may be helpful in establishing a diagnosis. Management of overt bleeding requires multidisciplinary approach involving hepatologists, endoscopists, surgeons, and interventional radiologists. Adequate resuscitation, reduction of portal pressure, and endoscopic therapeutic intervention remain the main principles of the initial treatment. This article reviews the existing evidence on PHE with emphasis on its classification, diagnosis, clinical manifestations, endoscopic appearance, pathological findings, and clinical management. A new schematic management of ectopic variceal bleed is also proposed.

文摘BACKGROUND Lymphangiomatosis is a multisystem disorder that is rarely localized to the gastrointestinal tract.Lymphangiomatosis usually has no specific clinical presentation and is easily misdiagnosed.A case report and review of the literature on lymphangiomatosis associated with protein-losing enteropathy will help to improve the overall understanding of this disease.CASE SUMMARY We report a case of lymphangiomatosis of the bowel and other solid organs.A 78-year-old man presented with recurrent bowel bleeding and protein-losing enteropathy,as well as cystic lesions in the spleen,liver,and kidney.Imaging examinations revealed many cystic lesions on the spleen,liver,kidney,and thickened wall of the ascending colon,as well as pleural effusion and ascites.Colonoscopy revealed a strawberry mucosa,variable spontaneous bleeding,and surface erosion located in the terminal ileum.Several cystic masses with a translucent and smooth surface as well as diffuse white spots were located in the colon.A laterally spreading tumor(LST)was located in the ascending colon.Pathology indicated highly differentiated adenocarcinoma(LST)and lymphangiomatoid dilation,and D2-40 was positive.The final diagnosis was lymphangiomatosis.The patient underwent surgery for LST and then was administered thalidomide 75-150 mg/d.His condition,however,did not improve.He eventually died 6 mo after the initial diagnosis.CONCLUSION Lymphangiomatosis usually occurs diffusely and can involve many organs,such as the spleen,kidney,liver,lung,mesentery,and bowel.Recurrent bowel bleeding or protein-losing enteropathy is an important indicator that should alert clinicians about the possibility of this disease when it afflicts the bowel.Doctors should improve the medical understanding of lymphangiomatosis.

文摘This review summarizes the current state of knowledge regarding the role of endothelial dysfunction in the pathogenesis of early and delayed intestinal radiation toxicity and discusses various endothelial-oriented interventions aimed at reducing the risk of radiation enteropathy. Studies published in the biomedical literature during the past four decades and cited in PubMed, as well as clinical and laboratory data from our own research program are reviewed. The risk of injury to normal tissues limits the cancer cure rates that can be achieved with radiation therapy. During treatment of abdominal and pelvic tumors, the intestine is frequently a major close-limiting factor. Microvascular injury is a prominent feature of both early (inflammatory), as well as delayed (fibroproliferative) radiation injuries in the intestine and in many other normal tissues. Evidence from our and other laboratories suggests that endothelial dysfunction, notably a deficiency of endothelial thrombomodulin, plays a key role in the pathogenesis of these radiation responses. Deficient levels of thrombomodulin cause loss of vascular thromboresistance, excessive activation of cellular thrombin receptors by thrombin, and insufficient activation of protein C, a plasma protein with anticoagulant, anti-inflammatory, and cytoprotective properties. These changes are presumed to be critically involved in many aspects of early intestinal radiation toxicity and may sustain the fibroproliferative processes that lead to delayed intestinal dysfunction, fibrosis, and clinical complications. In conclusion, injury of vascular endothelium is important in the pathogenesis of the intestinal radiation response. Endothelial-oriented interventions are appealing strategies to prevent or treat normal tissue toxicity associated with radiation treatment of cancer.

文摘AIM:To investigate the effect of mesalazine granules on small intestinal injury induced by naproxen using capsule endoscopy (CE).METHODS:This was a single center,non-randomized,open-label,uncontrolled pilot study,using the PillCam SB CE system with RAPID 5 software.The Lewis Index Score (LIS) for small bowel injury was investigated to evaluate the severity of mucosal injury.Arthropathy patients with at least one month history of daily naproxen use of 1000 mg and proton pump inhibitor co-therapy were screened.Patients with a minimum LIS of 135 were eligible to enter the 4-wk treatment phase of the study.During this treatment period,3 × 1000 mg/d mesalazine granules were added to ongoing therapies of 1000 mg/d naproxen and 20 mg/d omeprazole.At the end of the 4-wk combined treatment period,a second small bowel CE was performed to re-evaluate the enteropathy according to the LIS results.The primary objective of this study was to assess the mucosal changes after 4 wk of mesalazine treatment.RESULTS:A total of 18 patients (16 females),ranging in age from 46 to 78 years (mean age 60.3 years) were screened,all had been taking 1000 mg/d naproxen for at least one month.Eight patients were excluded from the mesalazine therapeutic phase of the study for the following reasons:the screening CE showed normal small bowel mucosa or only insignificant damages (LIS < 135) in five patients,the screening esophagogastroduodenoscopy revealed gastric ulcer in one patient,capsule technical failure and incomplete CE due to poor small bowel cleanliness in two patients.Ten patients (9 female,mean age 56.2 years) whose initial LIS reached mild and moderate-to-severe enteropathy grades (between 135 and 790 and ≥ 790) entered the 4-wk therapeutic phase and a repeat CE was performed.When comparing the change in LIS from baseline to end of treatment in all patients,a marked decrease was seen (mean LIS:1236.4 ± 821.9 vs 925.2 ± 543.4,P=0.271).Moreover,a significant difference between pre-and post-treatment mean total LIS was detected in 7 patients who had moderate-tosevere enteropathy gradings at the inclusion CE (mean LIS:1615 ± 672vs 1064 ± 424,P=0.033).CONCLUSION:According to the small bowel CE evaluation mesalazine granules significantly attenuated mucosal injuries in patients with moderate-to-severe enteropathies induced by naproxen.
文摘Development of oedema and hypoproteinaemia in a liver transplant recipient may be the first signs of graft dysfunction and should prompt a full assessment. We report the novel case of a patient who, years after liver transplantation developed a functional blind loop in an incisional hernia, which manifested as oedema and hypoproteinaemia secondary to protein losing enteropathy. After numerous investigations, the diagnosis was made by flurodeoxyglucose positron emmision tomography (FDG-PET) imaging. Surgical repair of the incisional hernia was followed several months later by resolution of the protein loss, and confirmed at a post operative FDG-PET scan at one year.
文摘AIM: To assess persistent symptoms and mortality in a cohort of patients with severe (grade 3-4) radiation enteropathy,59 patients were followed up after 15-18 years. METHODS: Fifty-nine patients were prospectively enrolled by twelve surgical departments. Primary malignant disease,radiation therapy and surgical management were recorded at inclusion. The cause of death or persistence of symptoms was examined in public death records or by interview of survivors. RESULTS: Thirty-nine patients had received radiation therapy for gynaecological cancers,twelve for urological cancers,four for gastrointestinal cancers and four for other malignancies. Forty-five patients (76%) required surgical intervention. Complications occurred in 11 (25%) operated patients. Forty-seven patients had died at the time of follow-up,seven (12%) died as a direct result of radiation enteropathy,while radiation enteropathy contributed to death in an additional seven patients. Four of the twelve surviving patients suffered from chronic debilitating symptoms of radiation enteropathy,while three had moderate symptoms. CONCLUSION: Patients with severe delayed radiation enteropathy have a high risk of persistence of symptoms after surgery. At least one in ten patients dies from radiation-induced bowel injury.

文摘Gluten-sensitive enteropathy,also known as coeliac disease(CD),is an autoimmune disorder occurring in genetically susceptible individuals that damages the small intestine and interferes with the absorption of other nutrients.As it is triggered by dietary gluten and related prolamins present in wheat,rye and barley,the accepted treatment for CD is a strict gluten-free diet.However,a complete exclusion of gluten-containing cereals from the diet is often difficult,and new therapeutic strategies are urgently needed.A class of proteins that have already emerged as drug targets for other autoimmune diseases are the heat shock proteins(HSPs),which are highly conserved stress-induced chaperones that protect cells against harmful extracellular factors.HSPs are expressed in several tissues,including the gastrointestinal tract,and their levels are significantly increased under stress circumstances.HSPs exert immunomodulatory effects,and also play a crucial role in the maintenance of epithelial cell structure and function,as they are responsible for adequate protein folding,influence the degradation of proteins and cell repair processes after damage,and modulate cell signalling,cell proliferation and apoptosis.The present review discusses the involvement of HSPs in the pathophysiology of CD.Furthermore,HSPs may represent a useful therapeutic target for the treatment of CD due to the cytoprotective,immunomodulatory,and anti-apoptotic effects in the intestinal mucosal barrier.
