Abstract
BACKGROUND Portal hypertensive enteropathy (PHE) is a small-bowel lesion observed in patients with portal hypertension. The clinical significance of endoscopic findings in PHE remains unclear. We aimed to clarify the clinical significance and predictive factors of capsule endoscopic findings in patients with PHE based on long-term outcomes. METHODS This retrospective study enrolled 55 patients with PHE (33 males and 22 females; median age, 64 years; range, 23-87) followed for > 3 years using capsule endoscopy (CE) between February 2009 and May 2023. We evaluated the clinical factors affecting PHE exacerbations and the effects of PHE exacerbations on gastrointestinal bleeding by comparing exacerbated and unchanged PHE groups. RESULTS Overall, 3 (5%) patients showed improvement, 33 (60%) remained unchanged, and 19 (35%) showed exacerbation on follow-up CE. In the exacerbated group, the rates of worsened fibrosis-4 index, exacerbated esophageal varices, and exacerbated portal hypertensive gastropathy were significantly higher than those in the unchanged group (21%, 32%, and 42% vs. 3%, 6%, and 12%, respectively; P < 0.05), and the rate of splenectomy was significantly lower in the exacerbated group than in the unchanged group (5% vs. 39%, respectively; P < 0.01). In multivariate analysis, exacerbation of esophageal varices and absence of splenectomy were significantly associated with PHE exacerbation. The rate of gastrointestinal bleeding after follow-up CE was significantly high in the exacerbated group (log-rank, P = 0.037). CONCLUSIONS Exacerbation of esophageal varices and splenectomy were significantly associated with exacerbation of PHE. Exacerbated PHE requires specific attention to prevent gastrointestinal bleeding.

Nationwide cohort study identifies clinical outcomes of angioectasia in patients with acute hematochezia. J Gastroenterol 2022; 58:367-378. [PMID: 36564578 DOI: 10.1007/s00535-022-01945-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 12/18/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND While angioectasia is an important cause of acute hematochezia, relevant clinical features remain unclear. This study aims to reveal risk factors, clinical outcomes, and the effectiveness of therapeutic endoscopy for patients with acute hematochezia due to angioectasia. METHODS This retrospective cohort study was conducted at 49 Japanese hospitals between January 2010 and December 2019, enrolling patients hospitalized for acute hematochezia (CODE BLUE-J study). Baseline factors and clinical outcomes for angioectasia were analyzed. RESULTS Among 10,342 patients with acute hematochezia, 129 patients (1.2%) were diagnosed with angioectasia by colonoscopy. The following factors were significantly associated with angioectasia: chronic kidney disease, liver disease, female, body mass index < 25, and anticoagulant use. Patients with angioectasia were at a significant increased risk of blood transfusions compared to those without angioectasia (odds ratio [OR] 2.61; 95% confidence interval [CI] 1.69-4.02). Among patients with angioectasia, 36 patients (28%) experienced rebleeding during 1-year follow-up. The 1-year cumulative rebleeding rates were 37.0% in the endoscopic clipping group, 14.3% in the coagulation group, and 32.8% in the conservative management group. Compared to conservative management, coagulation therapy significantly reduced rebleeding risk (P = 0.038), while clipping did not (P = 0.81). Multivariate analysis showed coagulation therapy was an independent factor for reducing rebleeding risk (hazard ratio [HR] 0.40; 95% CI 0.16-0.96). CONCLUSIONS Our data showed patients with angioectasia had a greater comorbidity burden and needed more blood transfusions in comparison with those without angioectasia. To reduce rebleeding risk, coagulation therapy can be superior for controlling hematochezia secondary to angioectasia.

Abstract
Complications of portal hypertension include portal hypertensive gastropathy and colopathy. These disorders may cause chronic or acute gastrointestinal bleeding. The diagnosis is made endoscopically; therefore, there is great variability in their assessment. Portal hypertensive gastropathy can range from a mosaic-like pattern resembling snakeskin mucosa to frankly bleeding petechial lesions. Portal hypertensive colopathy has been less well-described and is variably characterized (erythema, vascular lesions, petechiae). Treatment is challenging and results are inconsistent. Currently, available evidence does not support the use of beta-blockers for primary prevention. Further investigation of the pathogenesis, natural history, and treatment of these disorders is needed.

Abstract
BACKGROUND AND STUDY AIMS Polypoid lesions found during upper gastrointestinal endoscopy (UGIE) are occasionally found in patients with portal hypertension (PH). This study aimed to assess the true nature of such polypoid lesions using endoscopic ultrasound (EUS) and determine the accuracy of UGIE in differentiating between vascular and non-vascular lesions in PH. PATIENTS AND METHODS We retrospectively assessed all patients with PH referred for EUS due to polypoid lesions of unknown nature at UGIE over a 7-year period. Cases of known varices were excluded. UGIE findings were compared to EUS findings. RESULTS 66 patients were included (26 male). Commonest UGIE findings were: possible varices (19.4 %), polypoid/neoplastic lesion (52.8 %) and submucosal lesion (16.7 %). After EUS, the final diagnoses were: varices in 25 %, polypoid lesion with underlying vessel/varix in 27.8 % and non-vascular lesion or submucosal lesion in 47.2 %. The diagnostic accuracy of UGIE was suboptimal, since 28.6 % of possible varices were eventually found to be non-vascular, while 15.8 % of polyp/neoplastic looking lesions proved to be varices and 42.1 % were lesions with underlying vessel/varix. 50 % of submucosal lesions were eventually found to be varices. CONCLUSION Endoscopists should have a high index of suspicion of varices or polyps related to varices when assessing atypical looking polypoid lesions in patients with PH. In such cases EUS should be considered before obtaining biopsies.

Abstract
INTRODUCTION AND AIMS The role of capsule endoscopy (CE) in patients with liver cirrhosis (LC) has yet to be established; however, it is likely that it will remain a valuable diagnostic modality in several groups of patients with LC. The primary aims of the current prospective interventional study are to examine the prevalence for small bowel lesions and transit time of CE in the gastrointestinal tract in patients with LC with oesophageal varices (EVs) requiring endoscopic therapies. METHODS AND ANALYSIS The current study will be a single-centre prospective interventional study. Our study participants are LC subjects with portal hypertension who were determined to be necessary for prophylactic endoscopic therapies for EVs. From the view point of safety, patients with gastrointestinal obstruction or fistula or those being suspected of having gastrointestinal obstruction or fistula will be excluded from our study. Patients with implanted medical devices will be also excluded. CE will be performed prior to prophylactic endoscopic therapies in the same hospitalisation and relevant images will be analysed after 8 hours by expert endoscopists. This study will continue to recruit until 50 participants. ETHICS AND DISSEMINATION This study has received approval from the Institutional Review Board at Hyogo College of Medicine (approval no. 2680). The study protocol, informed assent form and other submitted files were reviewed and acknowledged. Final data will be publicly scattered regardless of the study results. A report releasing study results will be submitted for publication in a suitable journal after being finished in data collection. TRIAL REGISTRATION NUMBER UMIN000028433 (https://upload.umin.ac.jp/).

Abstract
Background and Aims. Gastrointestinal surveillance is a requirement prior to liver transplantation (LT), but small intestine examination is not generally undertaken. The aim of the present study was to evaluate the safety and efficacy of capsule endoscopy (CE) for patients with end-stage liver disease. Methods. 31 patients who needed LT were enrolled, and 139 patients who underwent CE over the same period of time acted as controls. Results. Frequency of successful achievement of evaluation of the full length of the small bowel, the mean gastric transit time, and the mean small bowel transit time were not significantly different between the two groups. Abnormalities in the small bowel were found in 26 patients. Comparative analysis revealed that history of EV rupture, history of EV treatment, red color sign of EV, and presence of PHG or HCC were significantly associated with patients with >2 two such findings (high score group). Conclusions. Small bowel examination by CE in patients before liver transplantation could be performed safely and is justified by the high rate of abnormal lesions detected particularly in patients with history of EV therapy or bleeding, red color sign, and presence of PHG or HCC. This study was registered in the UMIN Clinical Trial Registry (UMIN 000008672).

Abstract
AIM To elucidate the impact of the serum ferritin level, a surrogate indicator of hepatic iron accumulation, on hepatocarcinogenesis in chronic hepatitis C patients. METHODS Serum ferritin was measured in 487 chronic hepatitis C patients without history of hepatocellular carcinoma (HCC) after excluding patients in phlebotomy, those with overt chronic gastrointestinal bleeding and those who achieved sustained virological response before enrollment. Patients were divided into four groups (G1-G4) by quartile points of serum ferritin, with sexes separated. RESULTS The serum ferritin level was positively correlated with total bilirubin, aspartate aminotransferase, alanine aminotransferase (ALT), γ-glutamyltransferase, hemoglobin and AFP, and inversely correlated with prothrombin activity in both sexes. A significant difference in HCC incidence was observed only in male patients; the incidence was higher in G1 (≤80 ng/mL, n = 54) and G4 (≥323 ng/mL, n = 54) compared with that of G2 (81-160 ng/mL, n = 54) and G3 (161-322 ng/mL, n = 52). The spline curve indicating the relationship between the hazard ratio and serum ferritin level took the form of a J-shape for male patients. In multivariate analysis, G1 and G4 showed higher incidence of HCC among men with a hazard ratio of 2.19 (95% confidence interval, 1.02-4.70; P = 0.045) compared with G2 and G3, together with older age, lower serum albumin and ALT above the normal upper limit. CONCLUSION The serum ferritin level is an independent risk factor for HCC development in male patients with chronic hepatitis C when the level is extremely high or low.

Abstract
BACKGROUND Management of portal hypertensive colopathy (PHC) has been challenged by controversial results in its prevalence and clinical relevance. OBJECTIVE To describe the PHC prevalence and to evaluate the variability in diagnosis, the relation to severity of liver disease, and the incidence of severe outcomes. DESIGN Cross-sectional study. SETTING Endoscopic unit of a tertiary-care academic center in Rio de Janeiro, Brazil. PATIENTS Patients with cirrhosis with portal hypertension and controls paired for age and sex. INTERVENTIONS All patients were submitted to standard and image-enhanced colonoscopies, which were recorded in a coded video file and analyzed twice by a blinded endoscopist. MAIN OUTCOME MEASUREMENTS The prevalence of PHC. RESULTS A total of 51 patients with cirrhosis (55% male, mean age 59 years) and 51 healthy controls (43% male, mean age 61 years) were included. The top ranking colonoscopic findings were angiodysplasia-like lesions, nonspecific vascular pattern, red spots, and colorectal varices, all significantly more frequent in patients with cirrhosis compared with controls. PHC prevalence was 71% in patients with cirrhosis. For PHC, interobserver and intraobserver agreement (k values [standard error]) were 0.68 (0.09) and 0.63 (0.10), respectively. Intraobserver agreement for colonoscopic findings was satisfactory. PHC was not related to more severe liver disease or liver stiffness. Only 5 patients developed severe outcomes during follow-up. LIMITATIONS The exclusion of patients with cirrhosis without esophageal varices and the absence of an interobserver agreement analysis by double-blinded endoscopists. CONCLUSION PHC was highly prevalent in patients with cirrhosis, and its diagnostic agreement was satisfactory. PHC is not associated with relevant severe outcomes in a 12-month follow-up.

Abstract
Stool DNA testing has evolved into what is now a highly accurate and well-validated test for the screen detection of colorectal neoplasia. An optimized and automated multi-target stool DNA test (MT-sDNA) has achieved the same high point-sensitivities as reported for colonoscopy and significantly higher sensitivity than by fecal immunochemical blood testing for detection of early-stage cancer and advanced precancer. Thus, MT-sDNA sets a new high criterion standard for the noninvasive screen detection of colorectal neoplasia. With clinical application, MT-sDNA has potential to meaningfully address current gaps in our approach to CRC screening through benefits of its high accuracy on screening effectiveness, user-friendly features on patient compliance, and easy mail-out distribution on test access. The US Food and Drug Administration and Center for Medicaid and Medicare Services have recently completed their parallel reviews of MT-sDNA, which has just become available for clinical use. This review summarizes the recent clinical validation data on MT-sDNA, addresses central clinical questions at this front end of implementation, and touches on innovative future applications of stool DNA testing.

Abstract
AIM To describe a poorly known endoscopic entity associated with portal hypertension, characterized by polypoid lesions either in the stomach or small intestine of patients with cirrhosis. METHODS Between 2003 and 2012, patients with cirrhosis and portal hypertension underwent endoscopic workup of portal hypertension in our endoscopy unit. The clinical expression, endoscopic features of these lesions, and their pathological characteristics are described. RESULTS A total of 1538 patients were included, among which 14 (0.9%) presented polypoid lesions; these patients had evidence of portal hypertension and had dilated capillaries in the lamina propria. Four patients presented with severe anaemia or melaena and required treatment. Propranolol was administered to three patients, and one patient needed a transjugular intrahepatic portosystemic shunt in order to control bleeding. For asymptomatic patients in whom polypoid lesions were resected, no recurrence of lesions was observed during follow-up gastroscopy (median 36 months, range 7-85 months). CONCLUSION Portal hypertension-associated gastric or small intestine polypoid lesions may be associated with a significant risk of bleeding and are responsive to adequate treatment of portal hypertension.

Abstract
Portal hypertensive gastropathy (PHG) and colopathy (PHC) are considered complications of portal hypertension. Both entities are clinically relevant because they may cause insidious blood loss or even acute massive gastrointestinal hemorrhage. Endoscopic evaluation is necessary for the diagnosis of PHG and PHC. The existence of different endoscopic criteria for PHG and PHC makes consensus difficult and results in a broad range of reported prevalence. Therapy targeted at reduction of portal pressure and mucosal blood flow has been used to treat acute bleeding; nonselective β-blockers are the most frequently used agents. Further studies are needed to clarify the natural history, pathogenesis, and treatment of PHG and PHC.

Abstract
BACKGROUND AND AIM Effectiveness of capsule endoscopy (CE) for screening the small bowel in patients with portal hypertension (PHT) has been reported. However, few reports discuss CE detection of specific esophagogastric lesions related to PHT. Thus, we assessed whether CE is useful for detecting such lesions. METHODS One hundred nineteen consecutive patients with PHT comprised the study group. All had undergone esophagogastroduodenoscopy (EGD) prior to CE. The diagnostic yield of CE for esophageal varices (EVs), gastric varices (GVs), and portal hypertensive gastropathy (PHG) was evaluated. In addition, diagnostic yield in relation to form, location of the varices, grade, and extent of PHG was evaluated. RESULTS EVs were found by EGD in 71 patients. The overall diagnostic yield of CE for EVs was 72% (51/71). The diagnostic yield was significantly greater for F2/F3 EVs than for F1 EVs (87% vs 61%, P = 0.03). The diagnostic yield was significantly greater for Lm/Ls EVs than for Li EVs (85% vs 55%, P = 0.01). The diagnostic yield was significantly greater for locus superior/locus medialis EVs than for locus inferior EVs (85% vs 55%, P = 0.01). GVs were found by EGD in 29 patients. Only one case was detected by CE. PHG was found by EGD in 35 patients. The diagnostic yield of CE for PHG was 69% (24/35). There was no difference in diagnostic yield between cases of severe and mild PHG (82% vs 63%, P = 0.44). Diagnostic yield of CE for PHG in the gastric body was significantly greater than that in the fundus (100% vs 48%, P = 0.0009). CONCLUSION CE is reliable for diagnosis of F2/F3 and/or Lm/Ls EVs and of PHG in the gastric body.

Abstract
BACKGROUND Although capsule endoscopy is available as a minimally invasive imaging technique that contributes significantly to the detection of small bowel lesions, there are only a very few published descriptions of small bowel abnormalities in patients with portal hypertension. AIMS The aim of this study was to characterize the occurrence of small bowel lesions by means of capsule endoscopy in patients with portal hypertension, particularly those with compensated liver cirrhosis and associated anemia. METHODS Sixty consecutive patients who met our criteria underwent capsule endoscopy. The frequency, type, and distribution of small bowel lesions were determined, and clinical factors associated with the lesions were examined. RESULTS Small bowel abnormalities were found in 40 patients (67 %), including erythema (n = 32, 53 %), erosion (n = 10, 17 %), angioectasia (n = 9, 15 %), varices (n = 4, 7 %), and villous edema (n = 4, 7 %). Most lesions were located in the proximal or middle small bowel. Factors associated with the lesions were Child-Pugh class B (vs. class A, P = 0.0023), ascites (vs. no ascites, P = 0.0085), and portal hypertensive gastropathy (vs. no portal hypertensive gastropathy, P = 0.0434). CONCLUSIONS We found capsule endoscopy to be a useful diagnostic modality for detecting clinically significant small bowel lesions in patients with compensated liver cirrhosis. Based on our results, we suggest that this procedure should be especially considered for patients with Child-Pugh class B disease, ascites, and/or portal hypertensive gastropathy if they show evidence of gastrointestinal blood loss and/or iron-deficiency anemia.

Non-variceal gastrointestinal bleeding in patients with liver cirrhosis: a review. Dig Dis Sci 2012; 57:2743-54. [PMID: 22661272 DOI: 10.1007/s10620-012-2229-x] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2012] [Accepted: 05/01/2012] [Indexed: 02/08/2023]
Abstract
BACKGROUND Non-variceal gastrointestinal (NVGI) bleeding in cirrhosis may be associated with life-threatening complications similar to variceal bleeding. AIM To review NVGI bleeding in cirrhosis. METHODS MEDLINE, Scopus, and ISI Web of Knowledge were searched, using the textwords "portal hypertensive gastropathy," "gastric vascular ectasia," "peptic ulcer," "Dieulafoy's," "Mallory-Weiss syndrome," "portal hypertensive enteropathy," "portal hypertensive colopathy," "hemorrhoids," and "cirrhosis." RESULTS Portal hypertensive gastropathy (PHG) and gastric vascular ectasia (GVE) are gastric lesions that most commonly present as chronic anemia; acute upper GI (UGI) bleeding is a rare manifestation. Management of PHG-related bleeding is mainly pharmacological, whereas endoscopic intervention is favored in GVE-related bleeding. Shunt therapies or more invasive techniques are restricted in refractory cases. Despite its high incidence in cirrhotic patients, peptic ulcer accounts for a relatively small proportion of UGI bleeding in this patient population. However, in contrary to general population, the pathogenetic role of Helicobacter pylori infection remains questionable. Finally, other causes of UGI bleeding include Dieulafoy's lesion, Mallory-Weiss syndrome, and portal hypertensive enteropathy. The most common non-variceal endoscopic findings reported in patients with lower gastrointestinal bleeding are portal hypertensive colopathy and hemorrhoids. However, the vast majority of studies are case reports and, therefore, the incidence, diagnosis, and risk of bleeding remain undefined. Endoscopic interventions, shunting procedures, and surgical techniques have been described in this setting. CONCLUSIONS The data on NVGI bleeding in liver cirrhosis are surprisingly scanty. Large, multicenter epidemiological studies are needed to better assess prevalence and incidence and, most importantly, randomized studies should be performed to evaluate the success rates of therapeutic algorithms.

Abstract
Multiple duodenal ulcers are an uncommon finding in portal hypertensive duodenopathy (PHD). They represent a potential source of clinically significant bleeding from the upper gastrointestinal system in patients with cirrhosis. As this particular ulcer entity in relation to PHD has no distinguishing symptoms aside from those relating to the consequent bleeding, most of them are found either on routine endoscopic screening for cirrhotics or on endoscopic examination for cause(s) of bleeding in this patient population. The case documented below highlights many of the aspects of pathogenesis, associations, and consequences of this unique endoscopic finding in cirrhotic patients.

Abstract
BACKGROUND/AIMS The endoscopic findings and clinical relevance of portal hypertensive colopathy are not well described in Korea. We aimed to do a retrospective study of mucosal changes in the colon of patients with liver cirrhosis and to find their association with clinical characteristics. METHODS We reviewed the clinical data and endoscopic findings of 48 patients with liver cirrhosis and 48 patients, matched for age and sex, with irritable bowel disease (IBS) who underwent colonoscopy over a 5 year span. RESULTS Patients with liver cirrhosis were more likely to have colitis-like lesions and vascular abnormalities than IBS patients. Low platelet count (p=0.005) and severe esophageal varices (p=0.011) were associated with portal hypertensive colopathy, whereas the etiologies and severity of cirrhosis were not associated with these findings. CONCLUSIONS Portal hypertensive colopathy can be defined with colitis-like lesions or vascular lesions. These lesions are more frequently present in patients with more severe esophageal varices and thrombocytopenia.

Abstract
BACKGROUND Patients with hepatocellular carcinoma (HCC) sometimes suffer from obscure gastrointestinal bleeding. Portal hypertension (PH), common in cirrhosis, induces esophagogastric varices. Because of the location, PH also may influence mucosal abnormalities in the small intestine. The objective of this study is to estimate the prevalence of small intestinal mucosal abnormalities in HCC patients using capsule endoscopy (CE). PATIENTS AND METHODS We prospectively conducted CE in HCC patients, and analyzed the findings in relation to hepatic function, the number and size of HCC tumor and findings obtained by conventional endoscopy. RESULTS Thirty-six patients (aged 66.7 ± 7.5 years, 29 men) underwent CE. Abnormal findings in the small bowel were found in 16 patients (44%), angioectasias in eight patients (22%), erosions in five (14%), varices in four (11%), polyps in four (11%), and submucosal tumor in one (3%). The patients with angioectasia had a larger spleen index than the no abnormal lesions group (85.4 ± 15.8 vs 59.0 ± 24.4, P = 0.02). The former group had been more frequently treated for esophageal varices endoscopically (62% vs 15%, P = 0.02). Large HCC nodules seemed more common in the patients with angioectasia than subjects without abnormal lesions (38% vs 5%, P = 0.06). Small intestinal varices also seemed to have a positive association with large HCC. During the follow up after CE, one patient with small intestinal polyps suffered from obscure gastrointestinal bleeding. CONCLUSIONS CE revealed that HCC patients frequently have small intestinal mucosal lesions. In particular, small intestinal angioectasia, which may cause obscure gastrointestinal bleeding, seems to be associated with portal hypertension.

Abstract
There is limited data about the mucosal lesions of portal hypertensive enteropathy (PHE) detected by capsule endoscopy, and there is no scoring system to evaluate their severity. Our aim is to create a reliable scoring system for PHE, and to explore the possible usefulness of using transient elastograhy (TE) in that field. We compared the medical records of 31 patients with liver cirrhosis and portal hypertension with 29 control patients. We found that the mucosal lesions compatible with PHE were significantly more common in cirrhotic patients than in control patients (67.7% vs 6.9%, p<0.001). Cirrhotic patients with high TE score (p = 0.018), high Child-Pugh grade, large esophageal varices (EV), portal hypertensive gastropathy, and history of endoscopic variceal injection sclerotherapy or ligation (EIS/EVL) were significantly associated with PHE. Using our scoring system, we found that patients with higher TE score (p = 0.004), high Child-Pugh score (p = 0.011), larger EV (p = 0.006), and prior EIS/EVL (p = 0.006) were significantly associated with higher PHE score. We concluded that using our scoring system might be helpful in grading PHE severity, and TE might be a new non-invasive method for detecting the presence and severity of PHE in cirrhotic patients.

AIM To assess the presence of preneoplastic and neoplastic colonic lesions, as well as those related to portal hypertensive vasculopathy, and their association with liver disease in cirrhotic patients who are candidates for orthotopic liver transplantation (LT). METHODS Between October 2004 and December 2005, colonoscopy was performed in 92 patients who were LT candidates, aged >50 years old or aged <50 years old but with clinical indications. RESULTS Eighty-eight percent of the patients were > 50 years old, the mean age was 55.3 years (29-69) and 81.5% were males. The main etiology of cirrhosis was alcoholic (46.7%), and 21% were Child-Pugh class A. No abnormalities were detected in 20.7%. Polyps were discovered in 38% (35/92) of patients (adenomatous 65.2%; tubular type 86.7%). Six patients with adenomatous polyps had mild dysplasia, and one asymptomatic patient had a well-differentiated adenocarcinoma. An association was found between polyps and male sex (44% males vs 17.6% females; p=0.044) and Child-Pugh grade (63.2% Child A vs 32.9% Child B/C, p=0.016) but not with serum levels of carcinoembryonic antigen (CEA), age or etiology of liver disease. Portal hypertensive colopathy was found in 23.9%, rectal varices in 7.6% and internal or mixed hemorrhoids in 52.3%. CONCLUSION The prevalence of preneoplastic and neoplastic colonic lesions may support the use of colonoscopy in LT candidates aged >50 years-old or with a history suggesting lower gastrointestinal bleeding or other abnormalities.

Abstract
BACKGROUND The endoscopic abnormalities present in the small bowel (SB) of patients with portal hypertension (PH) are not well understood. This study sought to evaluate endoscopic findings of the SB in patients with PH by double balloon endoscopy (DBE). METHODS We evaluated the endoscopic findings of SB in 15 patients with PH and 49 controls without liver disease or PH. A total of 24 and 90 procedures were performed for PH patients and control patients, respectively, through oral and/or anal approaches. RESULTS Fourteen of the 15 patients exhibited villous abnormalities, including edema (73%), atrophy (40%), and reddening (47%) of villi. Vascular lesions, such as angiodysplasia-like abnormalities (67%), dilated/proliferated vessels (93%), and varices (7%), were observed in all patients with PH. Although they were associated with ascites, these abnormalities did not correlate with any laboratory findings. None of these abnormalities was observed in controls. Definitive or suspected bleeding sources were identified in 9 of 13 patients with both PH and obscure gastrointestinal bleeding (OGIB), which was similar to the incidence in controls with OGIB. Although the frequency of postprocedure fever (>37.5 degrees C) was higher in patients with PH in comparison to controls (29% vs. 2%, P < 0.01), endoscopic treatment under DBE was performed on 3 PH patients without serious complications. CONCLUSIONS Endoscopic abnormalities of the SB may be prevalent in patients with PH. Although postprocedure fever of DBE may occur more commonly in patients with PH, DBE is useful as both a diagnostic and therapeutic tool to evaluate the SB.

Abstract
INTRODUCTION Data on small bowel abnormalities in patients with portal hypertension (PHT) are limited. Bleeding from the gastrointestinal tract and anemia are common complications in these patients. Capsule endoscopy (CE) was used to evaluate small bowel (SB) pathology in patients with PHT and anemia, and possible associations with various parameters were examined. METHODS Thirty-five patients with PHT referred for CE investigation of the SB for anemia were prospectively enrolled in the study, as well as 70 age- and sex-matched control patients with anemia, normal liver function and no evidence of PHT who underwent CE. RESULTS Findings compatible with portal hypertensive enteropathy (PHE) were detected in 65.7% of the patients and in 15.7% of the controls chi2=26.641, P=0.000). Abnormalities in PHT patients included varices in 25.7%, diffuse changes of mucosa with inflammatory-like appearance in 42.9%, and angiodysplasias and/or spider angiomas in 22.9% of cases. The presence of PHE was significantly associated only with the presence of severe portal hypertensive gastropathy, while the presence of SB varices alone was significantly associated with the presence of severe portal hypertensive gastropathy, larger esophageal varices and the presence of colonic varices. CONCLUSIONS Varices, diffuse changes of mucosa with inflammatory-like appearance, and angiodysplasias and/or spider angiomas are detected more often in patients with PHT than in controls, and probably constitute the endoscopic characteristics of PHE. CE of the SB added a significant number of likely important findings to those detected by conventional endoscopic techniques for the clinical management of patients with PHT and anemia.

Abstract
BACKGROUND AND AIM The effects of portal hypertension in the small bowel are largely unknown. The aim of the study was to prospectively assess portal hypertension manifestations in the small bowel. METHODS We compared, by performing enteroscopy with capsule endoscopy, the endoscopic findings of 36 patients with portal hypertension, 25 cirrhotic and 11 non-cirrhotic, with 30 controls. RESULTS Varices, defined as distended, tortuous, or saccular veins, and areas of mucosa with a reticulate pattern were significantly more frequent in patients with PTH. These two findings were detected in 26 of the 66 patients (39%), 25 from the group with PTH (69%) and one from the control group (3%) (P < 0.0001). Among the 25 patients with PTH exhibiting these patterns, 17 were cirrhotic and 8 were non-cirrhotic (P = 0.551). The presence of these endoscopic changes was not related to age, gender, presence of cirrhosis, esophageal or gastric varices, portal hypertensive gastropathy, portal hypertensive colopathy, prior esophageal endoscopic treatment, current administration of beta-blockers, or Child-Pugh Class C. More patients with these endoscopic patterns had a previous history of acute digestive bleeding (72% vs. 36%) (P = 0.05). Active bleeding was found in two patients (5.5%). CONCLUSIONS The presence of varices or areas of mucosa with a reticulate pattern are manifestations of portal hypertension in the small bowel, found in both cirrhotic and non-cirrhotic patients. The clinical implications of these findings, as regards digestive bleeding, are uncertain, although we documented acute bleeding from the small bowel in two patients (5.5%).

Abstract
BACKGROUND Double-balloon endoscopy (DBE) and capsule endoscopy have opened up a new field of investigation regarding the small intestine. Although DBE has been widely used for diagnosis and treatment of different lesions in the small intestine, there is a paucity of information regarding endoscopic features of the small intestine in patients with liver cirrhosis (LC). METHODS Endoscopic images of the small intestine were taken in 21 patients with LC by DBE (EN-450P5/20 or EN-450T5/W). Biopsy specimens were taken from various parts of the small intestine and examined microscopically. Different endoscopic features of the small intestine were compared in relation to the clinical parameters of these patients. RESULTS Erythema and telangiectasia were observed in five patients (24%) and one patient (5%), respectively. In eight patients (38%), the small intestinal mucosa was edematous, and the intestinal villi of these patients were swollen and rounded, resembling herring roe. The patients with a herring roe appearance in the small intestine had advanced LC (Child's classification B and C), and all of them also had portal hypertensive gastropathy and portal hypertensive colopathy. In comparison with patients without a herring roe appearance in the small intestine, patients with a herring roe appearance had a significantly increased spleen volume (P<0.05) and decreased platelet counts (P<0.05). CONCLUSIONS Although preliminary, this study indicated that DBE may be useful for detecting different types of endoscopic lesions in patients with LC. A herring roe appearance seems to be one of the characteristic features of portal hypertensive enteropathy. However, further study will be required to develop insights about its pathogenesis.

Abstract
Cirrhosis is associated with global homodynamic changes, but the majority of the complications are usually manifested through the gastrointestinal tract. Therefore, Gastrointestinal Endoscopy has become an important tool in the multidisciplinary approach in the management of these patients. With the ever growing number of cirrhotic patients requiring pre-transplant endoscopic management, it is imperative that the community endoscopists are well aware of the pathologies that can be potentially noted on Gastrointestinal Endoscopy. Their timely management is also considered to have the utmost importance in being able to stabilize the patient until their transfer to a Liver Transplant Center. The aim of this manuscript is to give a comprehensive update and review of various endoscopic findings that a non-transplant endoscopist will encounter in the pre-transplant setting.

Abstract
Objective We wanted to evaluate the short-term effects of balloon-occluded retrograde transvenous obliteration (BRTO) for treating gastric variceal bleeding, in terms of the portal hypertensive changes, by comparing CT scans. Materials and Methods We enrolled 27 patients who underwent BRTO for gastric variceal bleeding and they had CT scans performed just before and after BRTO. The pre- and post-procedural CT scans were retrospectively compared by two radiologists working in consensus to evaluate the short-term effects of BRTO on the subsequent portal hypertensive changes, including ascites, splenomegaly, portosystemic collaterals (other than gastrorenal shunt), the gall bladder (GB) edema and the intestinal wall edema. Statistical differences were analyzed using the Wilcoxon signed rank test and the paired t-test. Results Following BRTO, ascites developed or was aggravated in 22 (82%) of 27 patients and it was improved in two patients; the median spleen volumes increased from 438.2 cm3 to 580.8 cm3, and based on a 15% volume change cut-off value, splenic enlargement occurred in 15 (56%) of the 27 patients. The development of new collaterals or worsening of existing collaterals was not observed in any patient. GB wall edema developed or was aggravated in four of 23 patients and this disappeared or improved in five; intestinal wall edema developed or was aggravated in nine of 27 patients, and this disappeared or improved in five. Statistically, we found significant differences for ascites and the splenic volumes before and after BRTO (p = 0.001 and p < 0.001, respectively). Conclusion Some portal hypertensive changes, including ascites and splenomegaly, can be aggravated shortly after BRTO.

Abstract
BACKGROUND The incidence and risk factors of gastrointestinal diseases in pre-liver transplant population are still a matter of debate. In a retrospective analysis, we addressed two questions: (1) Are there any lesions that occur at a higher prevalence than in the general population, and (2) are there patient characteristics that could predict their presence? MATERIALS AND METHODS All asymptomatic patients that successfully entered the waiting list of liver transplantation were recorded. We also compared results with those obtained from a control group of non-cirrhotic patients undergoing screening for colorectal cancer. Main outcome measures were the incidence and description of upper/lower gastrointestinal findings after screening endoscopic examination. RESULTS We retrospectively evaluated from April 2004 to July 2007 a total of 80 liver transplant candidates. The most frequent pathologies were esophageal varices (71.2% of subjects), portal hypertensive gastropathy (51.2%), hemorrhoids (22.5%), and colonic polyps (18.7%). Comparison with 80 non-cirrhotic patients matched for age and sex demonstrated an increased frequency in the cirrhotic group of ulcerative colitis (6.2 vs 0%; p = 0.02) and portal hypertensive colopathy (12.5 vs 0%; p = 0.001) in non-cirrhotic of diverticulosis (10 vs 25%; p = 0.01) and hemorrhoids (22.5 vs 40%; p = 0.02). The univariate analysis showed no significant correlation between colonic polyps and patients' variables, except a mild correlation with age not confirmed at the multivariate analysis. CONCLUSIONS The incidence of some benign gastrointestinal pathologies in liver transplant candidates is different from the asymptomatic population but not that of colorectal cancer or colonic polyps.

Abstract
OBJECTIVE Description of the clinical, endoscopic, and histopathologic detailed profiles of duodenal affection in portal hypertensive patients. METHODS A total of 105 patients with chronic liver disease and portal hypertension (PH) were included, upper endoscopy was performed, and two duodenal biopsies were obtained from the bulb and distal to the ampulla, for histopathologic examination. Twenty dyspeptic patients with normal upper endoscopy were included as controls. RESULTS Of the portal hypertensive patients, 54 (51.4%) had endoscopic duodenopathy (ED) lesions including erythema, erosions, ulcers, telangiectasia, exaggerated villous pattern, duodenal varices, and mixed lesions. ED was significantly higher in patients having severe than mild gastropathy (56.8% vs 23.5%, P<0.05) with no relation to size of esophageal varices or variceal bleeding. ED was a source of overt bleeding in 6.7% and occult bleeding in 2.9% of patients. Histopathologically, vascular changes included either capillary congestion (in more than half of biopsies) or capillary angiogenesis (in more than one-quarter of biopsies). Nonvascular changes included increased apoptosis (in about 16% of biopsies), fibrous proliferation (in about 4% of biopsies), and villous changes (in 11.4% of distal biopsies). All changes were not statistically different between patients with and without ED. In dyspeptic patients, only minimal histopathologic changes were noted. CONCLUSIONS ED is significantly higher in patients with severe gastropathy and causes gastrointestinal bleeding in 9.5% of patients. Capillary angiogenesis is an important vascular mechanism for adaptation to PH. The overall existence of histopathologic duodenopathy is much higher than that of ED and occurs with a similar prevalence in patients with and without ED.

Abstract
BACKGROUND AND AIMS Limited number of data are available on small bowel changes due to portal hypertension. The present retrospective, comparative study was aimed to analyse the diagnostic yield and to describe the findings with capsule endoscopy of cirrhotic patients with obscure gastrointestinal bleeding. PATIENTS AND METHODS Capsule endoscopy findings of 11 cirrhotic patients with portal hypertension and 22 non-cirrhotic patients with gastrointestinal bleeding who had undergone non-diagnostic upper endoscopy and colonoscopy were compared. Capsule video recordings were evaluated by two investigators at both workplaces. Patients after capsule endoscopy were followed-up until a mean of 19 (1-42) months. RESULTS In total 7 men and 5 women were examined at two medical centres in 48 months with a mean age of 66.2 (+/-7.6) years. The average period between the first clinical symptoms and capsule endoscopy was 15.7 (+/-14.9) months. During this period patients were hospitalized in an average of 2.8 (+/-1.3) times and 7.9 examinations were performed per patients prior to capsule endoscopy. A small bowel bleeding source was diagnosed in all 11 patients. Two definitive bleeding sources were observed in 7 patients (63%). Lesions connected to portal hypertension were found in all patients (8 angiodysplasias, 2 portal hypertensive enteropathies and 1 bowel varix). During the follow-up period rebleeding occurred in 27.3% of cirrhotic patients compared with 18.2% rebleeding rate in the control group. CONCLUSION Capsule endoscopy is a useful method in patients with portal hypertension and obscure gastrointestinal bleeding after negative upper endoscopy and colonoscopy. Multiple angiodysplasias are often diagnosed in the background of small bowel bleedings, and several bleeding sources frequently occur in these patients.

Abstract
Abnormalities of gastric mucosa in patients with portal hypertension are well documented. Manifestations of portal hypertension in small bowel and colon are less common. Colonic polypoid lesions microscopically consisting of a normal mucosa, with dilatation of submucosal vessels, have been described. We here report the first case of portal hypertensive duodenal polyp, responsible for gastro-intestinal bleeding. Endoscopic treatment turned out to be successful.

Abstract
An inflammatory etiopathogeny can be suggested in portal hypertensive enteropathy since infiltration of the intestinal wall by mononuclear cells has been described in this condition. This work was carried out with the intention of shedding light on this matter. Male Wistar rats were divided into 4 control groups and 4 groups with partial portal vein ligation at 1, 2, 3 and 15 months. TNF-alpha, IL-1beta and IL-10 were quantified in liver and ileum by ELISA. CO and NO were measured in splanchnic and systemic vein by spectrophotometry and Griess reaction, respectively. Expression of constitutive and inducible isoforms of NO and HO were assayed by Western blot in liver and ileum. An increased hepatic release of proinflammatory mediators (TNF-alpha, IL-1beta and NO) associated with intestinal release of anti-inflammatory mediators (IL-10, CO) occurs in an early evolutive phase (1 month) of experimental portal hypertension. On the contrary, in the long-term (15 months), the increase in the intestinal release of proinflammatory mediators (TNF-alpha, IL-1beta) is associated with an increase in the hepatic release of anti-inflammatory mediators (IL-10, CO). These results suggest that experimental prehepatic portal hypertension presents changes in the serum and tissular (liver and small bowel) concentrations of mediators which are considered as pro- and anti-inflammatory.

Abstract
The available data on the use of VCE in patients who have cirrhosis and portal hypertension are inadequate to reach a firm conclusion about the usefulness of this diagnostic tool in this patient population. In fact, only retrospective case series exist, in which the characteristics of the patients are heterogeneous in terms of severity of liver disease and of portal hypertension, etiology of cirrhosis, and indication for VCE. In addition, the controls included in the studies are heterogeneous or poorly described. In spite of this, it appears that in patients with portal hypertension, the small bowel frequently shows mucosal abnormalities. Such abnormalities appear to be particularly frequent in patients who have severe portal hypertension and in those with low hemoglobin levels. The clinical significance of these findings remains undefined, however, especially in view of the fact that small bowel lesions also have been found in about 10% of patients with arthritis not taking nonsteroidal anti-inflammatory drugs and in 13.8% of healthy subjects [41,42]. Therefore,large prospective studies are needed to evaluate the prevalence and clinical significance of small bowel mucosal changes in patients who have cirrhosis. Such studies should compare patients who have cirrhosis with healthy subjects. A comparison between cirrhotic patients with a history of intestinal bleeding and bleeding patients without cirrhosis also would be interesting.

Abstract
BACKGROUND AND AIMS Portal hypertensive gastropathy and colopathy are well described endoscopic abnormalities in patients with portal hypertension. Endoscopic abnormalities in the ileum in patients with portal hypertension have not been well described. The aim of the present study was to evaluate endoscopic abnormalities in the ileum of patients with portal hypertension. METHODS Patients with portal hypertension of various etiologies were included in the study. Upper gastrointestinal endoscopy was performed to record esophageal varices, gastric varices and portal hypertensive gastropathy. Colonoscopy with retrograde intubation of the ileum was performed and the presence of colorectal varices, colopathy and mucosal findings in the ileum were noted. RESULTS Forty-one patients (age 16-80 years, 33 men) were studied. Esophageal varices were present in all. Portal hypertensive gastropathy was present in 27/41 (66%) patients. Rectal varices were noted in 22/41 (54%) patients and 17/41 (42%) patients had features suggestive of colopathy. Ileum could be intubated in 38 patients (93%). Endoscopic abnormalities in the ileum were noted in 13/38 (34%) patients. Ileopathy as evident by endoscopic mucosal abnormalities was observed in 10/38 (26%) patients. Ileal varices were present in 8/38 (21%) patients. Three of these had ileal varices alone while the remaining five patients also had associated ileopathy The presence of ileopathy was significantly associated with the presence of portal hypertensive gastropathy and colopathy but not with esophageal, gastric or rectal varices. CONCLUSIONS Ileopathy occurs in one-third of patients with portal hypertension and is significantly associated with the presence of portal hypertensive gastropathy and colopathy.

Abstract
BACKGROUND The frequency of small-bowel mucosal changes in patients with portal hypertension is not known. The objective of the study is to better define the mucosal abnormalities of portal hypertensive enteropathy (PHE) and to determine whether these findings are associated with the severity of liver disease, esophageal varices, portal gastropathy, portal colonopathy, or other clinical characteristics. METHODS We compared the medical records of 37 patients with cirrhosis and portal hypertension with 34 control patients who underwent capsule endoscopy over a 3-year period. RESULTS Mucosal changes were found to be significantly more common in the cirrhotic patients than in the control patients (67.5% vs. 0, p < 0.001). The lesions included telangiectasias or angiodysplastic-like lesions in 9 (24.3%) patients, red spots in 23 (62.2%), and varices in 3 (8.1%). Active bleeding was seen during endoscopic examinations in 4 (10.8%) patients. A comparison of patients with and those without PHE showed that grade 2+ or larger esophageal varices, portal gastropathy, portal colonopathy, and Child-Pugh class C cirrhosis were all significantly associated with PHE. There were no differences between these two groups of patients with regard to the etiology of cirrhosis, gender, or history of esophageal variceal bleeding. CONCLUSIONS Mucosal abnormalities in portal jejunopathy include edema, erythema, and vascular lesions findings. A standardized grading system to classify the endoscopic appearance and the severity of portal enteropathy is proposed. The clinical import of these changes remains to be explained.

Abstract
PURPOSE Esophageal variceal sclerotherapy and band ligation seem not to affect the endoscopic findings of Portal Hypertensive Colopathy (PHC) of cirrhotic patients. The aim was to assess the effect of splenectomy and ligature of the left gastric vein on the PHC in carriers of hepatosplenic schistosomiasis mansoni who underwent this surgery when they were between 9 and 18 year-old. METHODS Fourteen patients, mean age of 19.1 +/- 3.1 years, were included in the postoperative group (GI). The follow-up was from 1 to 9 years. The preoperative group (GII) consisted of nine patients, mean age of 14.0 +/- 3.1 years. Full-length colonoscopy was carried out in all patients. Search was made for PHC lesions. RESULTS Telangiectasy (GI 100% vs GII 100%), increased vascularisation (GI 57.1% vs GII 100%), focal and diffuse hyperemia (GI 14.3% vs GII 66.7%), angiodysplasia (GI 7.1% vs GII 33.3%), and rectal varix (GI 0% vs GII 55.6%) were the most frequent findings. It was observed that the patients of this series tended to exhibit fewer hemodynamic manifestations of the PHC after treatment (postoperative versus preoperative - chi2 = 8.155 - p = 0.004). CONCLUSION Splenectomy and ligature of the left gastric vein tend to reduce the abnormal vascular findings of PHC in carriers of hepatosplenic schistosomiasis mansoni.

Abstract
AIM: In patients with liver cirrhosis and portal hypertension, portal hypertensive colopathy is thought to be an important cause of lower gastrointestinal hemorrhage. In this study, we evaluated the prevalence of colonic mucosal changes in patients with liver cirrhosis and its clinical significance.
METHODS: We evaluated the colonoscopic findings and liver function of 47 patients with liver cirrhosis over a 6-year period. The main cause of liver cirrhosis was post-viral hepatitis (68%) related to hepatitis B (6%) or C (62%) infection. All patients underwent upper gastrointestinal endoscopy to examine the presence of esophageal varices, cardiac varices, and congestive gastropathy, as well as a full colonoscopy to observe changes in colonic mucosa. Portal hypertensive colopathy was defined endoscopically in patients with vascular ectasia, redness, and blue vein. Vascular ectasia was classified into two types: type 1, solitary vascular ectasia; and type 2, diffuse vascular ectasia.
RESULTS: Overall portal hypertensive colopathy was present in 31 patients (66%), including solitary vascular ectasia in 17 patients (36%), diffuse vascular ectasia in 20 patients (42%), redness in 10 patients (21%) and blue vein in 6 patients (12%). As the Child-Pugh class increased in severity, the prevalence of portal hypertensive colopathy rose. Child-Pugh class B and C were significantly associated with portal hypertensive colopathy. Portal hypertensive gastropathy, esophageal varices, ascites and hepatocellular carcinoma were not related to occurrence of portal hypertensive colopathy. Platelet count was significantly associated with portal hypertensive colopathy, but prothrombin time, serum albumin level, total bilirubin level and serum ALT level were not related to occurrence of portal hypertensive colopathy.
CONCLUSION: As the Child-Pugh class worsens and platelet count decreases, the prevalence of portal hypertensive colopathy increases in patients with liver cirrhosis. A colonoscopic examination in patients with liver cirrhosis is indicated, especially those with worsening Child-Pugh class and/or decreasing platelet count, to prevent complications such as lower gastrointestinal bleeding.

Abstract
BACKGROUND The endoscopic appearance of portal hypertensive intestinal vasculopathy is well described in the stomach, the jejunum, and the colon, but there is no description of changes that occur in the ileum. METHODS The terminal ileum was intubated at colonoscopy in 44 patients with cirrhosis and portal hypertension and 46 control patients. Changes in the terminal ileum were noted. In addition, anorectal varices and colopathy were carefully noted and recorded. RESULTS Ileal varices and/or portal hypertensive ileopathy were present in 16 of 44 (36%) patients with cirrhosis and portal hypertension but not in any control patient ( p < 0.01). Ileal varices were present in 8 patients (18%) with cirrhosis/portal hypertension and none of the control patients ( p < 0.05). Portal hypertensive ileopathy was noted in 11 patients (25%) with cirrhosis and portal hypertension and in none of the control patients ( p < 0.05). Ileal varices had no association with any other parameter studied. However, ileopathy was observed in 9 of the 23 patients with colopathy and in only two of the 21 patients without colopathy ( p < 0.05). CONCLUSIONS Ileal varices and mucosal changes of portal hypertensive ileopathy occur in patients with cirrhosis and portal hypertension. In the population studied, ileopathy was significantly more common in patients who had portal hypertensive colopathy.

Abstract
Portal hypertension is a frequent complication of chronic liver disease, detected not only in schistosomiasis, but also in cirrhosis of any etiology. Vascular alterations in the colonic mucosa are a potential source for acute or chronic bleeding and have been observed in patients with portal hypertension. The purpose of this prospective study was to describe and propose a classification for the vascular alterations of portal hypertension in the colonic mucosa among patients with hepatosplenic schistosomiasis mansoni. One or more alterations of portal colopathy were observed in all patients and they were classified according to their intensity, obeying the classification proposed by the authors. Portal colopathy is an important finding in hepatosplenic schistosomiasis and might be the cause of lower gastrointestinal bleeding in patients with severe portal hypertension.

Abstract
BACKGROUND AND AIMS To do a histomorphometric study of vascular changes in colonic mucosa of patients with portal hypertension (PHT) and to find their association with clinical and upper and lower gastrointestinal endoscopic observations. METHODS Full length colonoscopy was carried out in 55 patients with portal hypertension and 25 controls. Hemorrhoids, anorectal varices and colopathy were carefully looked for and recorded. Two biopsies each were taken from the caecum, ascending colon, transverse colon, descending colon and rectum. Sections from all the five sites were examined for histopathological changes with special reference to changes in mucosal capillaries. Morphometric assessment of the diameter of the capillary and thickness of the capillary wall was performed. These histomorphometric changes were correlated with clinical parameters and findings of upper and lower gastrointestinal endoscopic findings. RESULTS Dilated and congested capillaries as well as capillaries with irregular thickening of the wall were seen in a significantly higher number of sections from patients than controls in biopsies from all the five sites from caecum to rectum. On morphometry, the diameter of the capillaries and the thickness of the capillary wall in biopsies from all the five sites in patients was significantly higher than that in the control group. Apart from vascular changes, edema and inflammatory infiltrate in lamina propria were the other significant histological features noted. No significant association between clinical and endoscopic features and histomorphometric assessment was found. CONCLUSION Dilated tortuous mucosal capillaries with irregular thickening of wall, edema of lamina propria and mild chronic inflammatory infiltrate are the major histopathological changes seen in colonic biopsies of patients with PHT, showing that PHT produces changes in the colonic mucosa similar to those seen in the mucosa of upper GI tract. However, the histological changes had no correlation with the clinical or endoscopic findings except that the thickness of the capillary wall was higher in patients who had undergone endoscopic sclerotherapy as opposed to those who had not received sclerotherapy.
