RESUMEN
BACKGROUND: Cytapheresis is a non-pharmacologic treatment option in which depleting elevated/activated leucocytes is known to exacerbate and perpetuate ulcerative colitis (UC) by releasing inflammatory cytokines. Therefore, it is a relevant treatment for elderly patients who wish to avoid pharmacologicals. METHODS: The efficacy of Cytapheresis for remission induction in 72 patients who received Cytapheresis for active UC at our hospital was retrospectively evaluated. Patients included 11 elderly cases, patients on steroids, biologics, calcineurin inhibitor, and 13 with extra-intestinal complications. Lichtiger's UC clinical activity index ≤4 meant remission was assessed at the end of therapy and then 1 month later. The efficacy on extra-intestinal manifestations meant improvement of the main morbidity. RESULTS: At the end of Cytapheresis therapy, the remission rate in the elderly was 36.4%, and 54.2% in the non-elderly patients. One-month post Cytapheresis, the remission rate in the elderly had increased to 72.7% (p = 0.042), but to 58.3% in the non-elderly, suggesting a delayed response phenomenon in the elderly. The efficacy of Cytapheresis in 4 cases with loss of response to biologics was 75%, and 84.6% in the 13 patients with extra-intestinal complications, indicating a dramatic efficacy on dermatitis and arthralgia. CONCLUSIONS: Unlike pharmacologicals, the efficacy of Cytapheresis appears to be time dependent. Accordingly, in the elderly, we observed a delayed response, indicating that elderly patients may respond beyond the end of Cytapheresis therapy. Therefore, patients who do not show efficacy at the end of Cytapheresis therapy should be followed up for delayed response. Further, Cytapheresis is favored by patients for its good safety profile.

BACKGROUND In recent years, a plethora of therapeutic agents for ulcerative colitis (UC), especially novel biologics (Bio), have become available. Although it is now possible to use biological drugs, there should be no need for frequently changing medications. To avoid first-pass metabolism in the liver, thus reducing systemic bioavailability, budesonide foam has been applied as a topical steroid. We therefore evaluated whether budesonide foam has therapeutic value in UC patients who responded inadequately to Bio or to tacrolimus. MATERIAL AND METHODS We enrolled 10 patients who were experiencing an inadequate response to Bio (n=7) or to tacrolimus (n=3) at Juntendo University. We used Lichtiger's index to assess UC activity and clinical response. RESULTS Of the study patients, 4 were receiving adalimumab, 3 golimumab, and 3 tacrolimus. The average Lichtiger's index before budesonide administration was 7.1 (range 13-3), which improved to 3.4 (range 7-0) after budesonide therapy (p=0.01). Notably, 4 of the 6 cases with a Lichtiger's index >4 before budesonide administration achieved improvement of ≥3 points or remission. CONCLUSIONS Although the number of patients was small, budesonide foam had significant efficacy when added to the treatment of patients having an inadequate response to Bio or to tacrolimus. These results suggest that in cases responding poorly to Bio, adding budesonide foam as combination therapy can achieve a clinical remission.

Ulcerative colitis (UC) is 1 of the 2 major phenotypes of chronic inflammatory bowel disease (IBD), which afflicts millions of individuals throughout the world with debilitating symptoms that impair function and quality of life. Further, IBD often affects women during childbearing age. Indeed, UC activity frequently increases during pregnancy, and the medications used to induce remission may adversely affect the health of the mother and the unborn child. We report successful induction of a remission in a UC case who experienced a flare-up in the first trimester of pregnancy. Upon relapse, she was treated with steroids and adsorptive granulomonocytapheresis (GMA) with the Adacolumn plus tacrolimus. This combination therapy induced a stable remission that was maintained during her entire pregnancy. She gave birth to a healthy child at 36 weeks of pregnancy with no maternal or fetal complications. Our experience indicates that GMA, as a non-drug therapeutic intervention with a favorable safety profile, plus tacrolimus might be a relevant treatment option for patients with active IBD during pregnancy. A future study of a large cohort of pregnant patients should strengthen our findings.
RESUMEN
BACKGROUND [color=black]Bowel preparation is an important factor for an optimal outcome of colonoscopy. Recently, polyethylene glycol (PEG) solution has been in common use for bowel cleansing for colonoscopy, but some patients are intolerant of PEG because of taste or volume. A low-volume PEG administered with ascorbic acid solution (PEG-Asc) was designed to improve tolerability, but the administration of this method is more complex than that with PEG alone. This study aimed to compare bowel cleansing efficacy, safety, and tolerability of 1 L PEG-Asc with a 2 L PEG preparation with use of sennosides and mosapride.[/color] MATERIAL AND METHODS [color=black]This was a prospective, single-center, non-inferiority trial that included 112 patients (PEG-Asc group, 68; PEG group, 44). The primary endpoint was the efficacy of colon cleansing assessed by endoscopists using a validated 4-point scale according to the Aronchick scale and was verified by a blinded investigator. Acceptability, tolerability, and adenoma detection rate (ADR) of these 2 regimens were secondary endpoints.[/color][color=black] [/color] RESULTS [color=black]We found no statistically significant differences between the groups in colon-cleansing efficacy or in the adenoma detection rate (ADR). Moreover, overall, patients significantly favored PEG-Asc over PEG, reflecting better acceptance of PEG-Asc. Additionally, more patients favored PEG-Asc over PEG for a hypothetical future colonoscopy. [/color] CONCLUSIONS [color=black]The alternate 1 L PEG-Asc regimen and standard 2 L PEG regimen were clinically equivalent with respect to cleansing efficacy, safety, and ADR, and more patients favored PEG-Asc than PEG. This alternate regimen may improve patient compliance and acceptance of surveillance colonoscopy.[/color].

BACKGROUND: In ulcerative colitis (UC) patients, cytapheresis depletes elevated and activated leucocytes, which are known to release inflammatory cytokines including tumor necrosis factor (TNF)-α. Further, there are UC patients who develop erythema nodosum (EN) or pyoderma gangrenosum (PG) as extra-intestinal manifestations of UC. METHODS: Between 2008 and 2015, 181 consecutive patients with active UC received cytapheresis with either a granulocyte and monocyte apheresis (GMA) column or with a leucocyte removal filter (LCAP) as remission induction therapy. Each patient received weekly or intensive (2-3 sessions/week) cytapheresis up to 10 sessions. In 13 patients, UC was complicated by EN or PG. Lichtiger's clinical activity index (CAI) ≤4 meant remission, while ≥3 decrease in CAI meant response to therapy. Prednisolone sparing and the changes in the extra-intestinal manifestations were factored for assessing treatment efficacy. RESULTS: The overall remission and response rates were 52.5% and 71.8%, respectively, CAI fell from 9.4 ± 3.3 to 4.9 ± 3.5 (P < 0.001). The efficacy rates in subgroups on concomitant corticosteroid, anti-TNF or tacrolimus, and those without concomitant medications were not significantly different (P > 0.05). However, in 84 patients on prednisolone, the average daily prednisolone dose was reduced from 18.15 to 12.43 mg/day (P < 0.001) with 21.7% being corticosteroid free. All patients with EN or PG showed favorable response to cytapheresis, notably 2 EN patients achieving remission after just 2 cytapheresis sessions without concomitant medication. CONCLUSIONS: In this retrospective efficacy evaluation, cytapheresis was effective as remission induction therapy with steroid sparing effect and desirable safety profile. Further, patients with EN or PG responded favorably to cytapheresis.

BACKGROUND AND AIM: Post-polypectomy bleeding (PPB) is the most common complication of endoscopic procedures. To reduce the risk of thromboembolic incidents, Japanese guidelines for gastroenterological endoscopy were revised to indicate that antithrombotic agents were not to be discontinued for endoscopic treatment. However, carrying out endoscopic procedures under antithrombotic medication potentially increases the incidence of hemorrhagic complications. The present study investigated the impact of the revised guidelines on the frequency of complications after colonoscopic procedures. METHODS: The surveillance period comprised the year before the initiation of the new guidelines (2012), which served as a control period, and 2 years after initiation of the new guidelines (2013 and 2014). During the control period, 3955 cases were examined colonoscopically and 1601 lesions were treated endoscopically. During the 2-year period under the new guidelines, 8749 colonoscopies and 3768 endoscopic treatments were carried out. Changes in treatment methods and rates of complications were compared. RESULTS: PPB rate was not significantly different before and after the revision (0.87% vs 1.01%). With the new guidelines, PPB rates in antithrombotic non-users and users were 0.60% and 3.13%, respectively (OR 5.11, P = 0.000). Multivariable analysis showed that the risks for PPB were as follows: heparin bridging therapy (OR 6.34, P = 0.0002); low-dose aspirin (LDA) continuation (OR 5.30, P = 0.0079); and lesion size (OR 1.06, P < 0.0001). CONCLUSION: The present study showed that the overall PPB rate under the new guidelines was not significantly higher when compared with the previous data obtained before the new guidelines were introduced.

BACKGROUND: Most mucosal defects that occur with endoscopic submucosal dissection (ESD) can be closed completely using endoscopic clips. However, benefits of such closure in wound healing are unknown. A randomized controlled study evaluated the efficacy of closure with clips compared with no closure. METHOD: Twenty-eight patients who had undergone ESD were randomly divided into two groups: closure (n = 14) and non-closure groups (n = 14). In the closure group, the mucosal defect resulting from ESD was closed using endoscopic clips. Four weeks after ESD, defects in both groups were observed by colonoscopy. Efficacy was based on change in the area of the defect, percentage of complete healing in each group, and complications. RESULT: Data were analyzed for 26 of the 28 patients (13, closure group; 13, non-closure group). All tumors were resected en bloc by ESD without bleeding or perforation. In the closure group, the area of the defect just after ESD was 677 ± 306 mm(2) (mean ± SD) as determined by the size of the removed lesion and had decreased to 2.17 ± 4.51 mm(2) at 4 weeks after ESD (reduction, 99.7 %), but in the non-closure group that area was 790 ± 221 mm(2) and had decreased to 27.42 ± 25.72 mm(2) at 4 weeks post-ESD (reduction, 96.2 %). The reduction rate was significantly higher in the closure than in the non-closure group (99.7 vs. 96.2 %, p = 0.010). Complete healing was 69.2 % in the closure group vs. 7.7 % in the non-closure group (p = 0.005). Multivariate analysis showed that closure of the mucosal defect (OR 24.029, 95 % CI 2.09-276.15, p = 0.011) was an independent factor associated with complete healing at 4 weeks after ESD. Delayed perforation or post-ESD bleeding was not observed in any participant. CONCLUSION: Use of endoscopic clips for closure of defects after ESD is safe and efficacious in accelerating wound healing. TRIAL REGISTRATION: UMIN-CTR UMIN000009112.

Aim. To examine optimal timing for resuming antithrombotic agents and risk factors for delayed bleeding after endoscopic resection of colorectal tumors. Method. Of 1,970 polyps larger than 10 mm removed by polypectomy, endoscopic mucosal resection, or endoscopic submucosal dissection, delayed bleeding, which was designated as bleeding that occurred 6 or more hours after endoscopic treatment, occurred in 52 cases (2.6%); 156 nonbleeding cases matched for age and gender were controls in this single-institution retrospective case-control study. We investigated (1) patient-factors: resuming antithrombotic agents within 5 days following endoscopic resection, hypertension, and diabetes mellitus; and (2) tumor-factors: morphology, size, location, and resection technique by conditional logistic regression. Results. By multivariate analysis resumption of anticoagulants within 5 days was a significant risk factor for delayed bleeding (OR 10.2; 95% CI = 2.7-38.3; P = 0.0006). But resuming a thienopyridine within 5 days was not (OR 0.9; 95% CI = 0.1-2.6; P = 0.40). Other patient- and tumor-factors were not significant. Conclusion. Resuming anticoagulants within 5 days after endoscopic treatment was associated with delayed bleeding whereas resuming thienopyridines was not.
RESUMEN
Optimal bowel preparation is essential for the safety and outcome of colonoscopy. A solution containing polyethylene glycol (PEG) is often used as a bowel cleansing agent, but some patients are intolerant of PEG, and this may lead to discontinuation of colonoscopy. Sodium phosphates (NaP) tablets are designed to improve patient acceptance and compliance. The objective of this study was to compare bowel preparation efficiency and patient acceptance of a 30 NaP tablet preparation (L-NaP) and a 2 L PEG preparation. Patients were randomized into either the L-NaP or PEG group. The primary endpoint was the efficiency of colon cleansing as assessed by a validated four-point scale according to the Aronchick scale by endoscopists and was verified by blinded investigators. The secondary endpoints were patients' tolerability and acceptance. Colon-cleansing efficiency was not significantly different between the two preparations. However, patients' overall judgment was significantly in favor of L-NaP, reflecting better acceptance of L-NaP than PEG. Additionally, more patients favored L-NaP over PEG in a hypothetical future occasion requiring colonoscopy.
RESUMEN
Colorectal laterally spreading tumors (LSTs), which are classified into granular (LST-G) and nongranular (LST-NG) types, are a good indication for endoscopic treatment. In practice, the nongranular type is more difficult to remove endoscopically than the granular type. It might be assumed that some histological differences exist between these subtypes. The objective of this study was to analyze histological features of laterally spreading tumors and compare between the granular and the nongranular types. A total of 32 cases of LSTs resected endoscopically being intramucosal tumors with no previous treatment were analyzed. The disposition of the muscularis mucosae, the vascular density, and the degree of fibrosis of the submucosal layer were determined. The outline of the muscularis mucosae in LST-NG was almost flat, but that of LST-G was wavy. The submucosal vascular density was significantly greater in the LST-NGs (61.4 ± 24.3/mm(2)) than in the LST-Gs (43 ± 22.4/mm(2); P = 0.033). There was no clear difference in the degree of submucosal fibrosis between the subtypes. A flat disposition of the muscularis mucosae and a more densely vascularized submucosal layer were characteristics of LST-NGs compared to the LST-Gs. These findings may play a role when performing the endoscopic resection of LSTs.
RESUMEN
BACKGROUND: Endoscopic submucosal dissection (ESD) allows en bloc resection of superficial colorectal tumors regardless of size. However, ESD is technically difficult, hazardous, and time consuming. New devices may help overcome these drawbacks. We focused on traction methods and designed a new traction device, the "S-O clip." Its main advantage is that it allows direct visualization of the cutting line during submucosal dissection. Moreover, it can be used at any location without withdrawing the endoscope. The purpose of this study was to evaluate the efficacy and safety of traction device-assisted ESD for large colorectal tumors using the S-O clip. METHODS: Between August 2010 and December 2011, ESD was performed in 70 patients with a superficial colorectal tumor ≥20 mm in diameter in our department. Patients were randomized into two groups: 27 cases in the S-O clip-assisted ESD group and 23 cases in the conventional ESD group. Included in the analysis were patient's gender and age, tumor form, size, and location, rate of en bloc resection, procedure time, presence or absence of intraoperative perforation or delayed bleeding, and pathological findings. Subgroup analysis stratified by these factors and multivariate analyses were conducted. RESULTS: In the S-O clip-assisted ESD group, all 27 tumors were resected en bloc without any complications. Although a micro perforation occurred in one patient in the conventional ESD group, further surgical treatment was not required. None of the other 22 cases in the conventional ESD group experienced complications. The mean procedure time for the S-O clip-assisted ESD group was significantly shorter than for the conventional ESD group (37.4 ± 32.6 vs. 67.1 ± 44.1 min, p = 0.03). No significant between-group differences were found for the other factors. CONCLUSION: Our results demonstrated that S-O clip-assisted ESD is safe and fast for en bloc resection of large superficial colorectal tumors.

BACKGROUND: We examined the incidence of and factors associated with fever, as well as the frequency of bacteremia, in patients who had undergone endoscopic submucosal dissection (ESD) for colorectal tumor. METHOD: A total of 199 patients (120 male and 79 female) were included. The patients were classified into two groups based on the body temperature on the day after ESD treatment: group A, body temperature <37 °C; and group B, body temperature ≥37 °C. The following factors were analyzed to determine their potential association with post-ESD fever: gender, age, tumor size, form, location, and presence or absence of intraoperative perforation. In addition, blood samples from 50 patients were obtained for blood culture and 16S rRNA gene analysis by polymerase chain reaction. RESULTS: Group A included 106 patients (70 male and 36 female), with a median age of 63 years. Group B included 93 patients (50 male and 43 female), with a median age of 70 years. The incidence of post-ESD fever in the entire cohort was 46.7%. Univariate analysis based on comparison between groups A and B showed that the following factors were significantly associated with post-ESD fever: age [mean ± standard deviation (SD)], 64.5 ± 9.2 versus 68.5 ± 10.8 years, P = 0.006; and tumor size (mean ± SD) 30.6 ± 10.8 versus 39.1 ± 16.6 mm, P < 0.001. Logistic regression analysis for post-ESD fever also found that age {odds ratio 1.04 (95% CI [1.01-1.07], P = 0.009)} and lesion size {odds ratio 1.05 (95% CI [1.03-1.08], P = 0.0002)} were closely associated with post-ESD fever. Of the 50 patients who had blood samples cultured and 16S rRNA gene analyzed, bacteria in blood culture and the 16S rRNA gene were not detectable in any of the samples from the 50 patients. CONCLUSIONS: This study indicated that older patients and patients with large tumors were more likely to develop post-ESD fever, but there was a low probability that bacteremia was the cause of fever.

OBJECTIVE: Capsule endoscopy (CE) is an established technique for the detection and diagnosis of obscure gastrointestinal bleeding (OGIB). Flexible spectral imaging color enhancement (FICE) is a software feature of RAPID 6.5. This study assessed the value of FICE for accurate identification of red lesions during CE. METHODS: We randomly selected 10 patients who underwent CE for OGIB at Juntendo University. The CE images were read by five endoscopists. Small bowel videos, which were recorded by regular CE devices (PillCam SB2, Given Imaging), were evaluated on RAPID 6.5. We standardized the reading condition to a dual view, at a speed of 20 frames/s in manual mode. This interpreted FICE-CE images obtained at settings 1-3. Both conventional and FICE images were read at random. We defined a conventional image as standard and investigated the potential of FICE in detecting small intestinal lesions by the Steel-Dwass test. RESULTS: We considered that conventional images represented baseline (100). On this basis, detection rates for FICE images were as follows: FICE1 = 266.4 ± 33.1 (p < 0.0001); FICE2 = 255.4 ± 25.6 (p < 0.0001); and FICE3 = 117.0 ± 12.3 (p = 0.9447). Detection rates using FICE1 and FICE2 images were significantly higher than conventional CE images. FICE1 and FICE2 were more useful in detecting erosions than conventional CE (p < 0.0001) and FICE3 (p < 0.0001). CONCLUSIONS: FICE-CE has a high level of visibility by transparentizing bile or enhancing the color difference associated with reddish mucosa. We found that FICE-CE images were useful in the diagnosing of small intestinal lesions.

BACKGROUND: Although various traction devices exist for endoscopic submucosal dissection (ESD), the effects of the material used in the devices on the human body has not been considered. Moreover, there has been no report on a device that facilitates dissection both on the oral and anal side of the lesion. We made a traction device that has no deleterious effects on the body and is noninvasive, easy to use, and enables a bilateral approach in ESD. We report the process of its creation and a prospective evaluation of its usage in actual ESD procedures. METHODS: This study is prospective case control study. Thirty-seven patients for whom the device would be used were consecutively and prospectively enrolled (device used group). Control subjects in whom the device would not be used and who had lesions matched for size and location with those of the device used group were randomly selected (device not used group). Both groups were classified into three subgroups according to treatment difficulty: group A: easy; group B: intermediate; and group C: difficult. The dissection time per cm(2) in each group was examined. RESULTS: Dissection times in the device not used group/device used group were as follows: group A, 5.8/2.1 min/cm(2) (p < 0.01); group B, 6.1/3.8 min/cm(2) (p < 0.05); and group C, 7.9/3.6 min/cm(2) (p < 0.01), respectively. CONCLUSIONS: The newly developed medical ring was shown to be feasible and safe and allowed excellent visualization through suitable tension and facilitated rapid gastric ESD.

BACKGROUND: Multiple carcinoid tumors of the small intestine are rare and are very difficult to detect preoperatively. CASE REPORT: A 75-year-old woman in whom the bleeding focus could not be found by upper and lower endoscopy and abdominal CT was admitted for evaluation of anemia. We examined the patient with total double-balloon endoscopy (DBE) and located multiple submucosal tumors. The multiple carcinoid tumors were resected successfully under laparoscopy. CONCLUSIONS: We report a case of a successful laparoscopic operation for multiple carcinoid tumors in the small intestine without intraoperative endoscopy. Total digestive tract observation using DBE is very useful for laparoscopic operation for multiple tumors in the small intestine.

OBJECTIVE: Capsule endoscopy (CE) allows direct examination of the small bowel in a safe, noninvasive and well-tolerated manner. Nonetheless, experience indicates failure to reach the cecum in 20-30% of patients within the 8 hour battery life. Attempts to improve the completion rate (CR) as defined by reaching the cecum have been unsuccessful. This study was to investigate the relationship between patients' physical activity and CR. METHODS: Between January 2009 and January 2010, 76 patients (44 men, 32 women; median age 64.5 yr) underwent CE for the diagnosis of small intestinal disorders. Indications for CE were obscure gastrointestinal bleeding/anemia (62 cases), others (14 cases). Patients were divided into an outpatient group (n=23), mild bed rest group (n=35) and strict bed rest group (n=18). RESULTS: For all patients, the average gastric transit time was 65.5 minutes, small bowel transit time was 301.4 minutes and the CR was 86.8%. However, the CR was 100% (23/23) in the outpatient group, an 85.7% (30/35) in the mild bed rest group, and 72.2% (13/18) in the strict bed rest group. The CR increased with physical activity of patients by Cochran-Armitage Trend Test (p=0.009). In multivariate logistic regression analyses, low physical activity was a significant risk factor for failure to reach the cecum during CE examination; adjusted OR: 3.39, 95% CI: 1.01-11.42 (p=0.048). CONCLUSION: Our observations suggested that increasing physical activity would increase the likelihood of a complete bowel examination by CE. Further, for CE, inconvenient bowel preparations like the use of polyethylene glycol may be avoided.

AIM: To validate the clinical relevance of autofluorescence imaging (AFI) endoscopy for the assessment of inflammatory ulcerative colitis (UC). METHODS: A total of 572 endoscopic images were selected from 42 UC patients: 286 taken with white light imaging (WLI) and 286 with AFI from the same sites. WLI images were assessed for overall mucosal inflammation according to Mayo endoscopic subscore (MES), and for seven characteristic endoscopic features. Likewise, AFI photographs were scored according to relative abundance of red, green and blue color components within each image based on an RGB additive color model. WLI and AFI endoscopic scores from the same sites were compared. Histological evaluation of biopsies was according to the Riley Index. RESULTS: Relative to red (r = 0.52, P < 0.01) or blue (r = 0.56, P < 0.01) color component, the green color component of AFI (r = -0.62, P < 0.01) corresponded more closely with mucosal inflammation sites. There were significant differences in green color components between MES-0 (0.396 ± 0.043) and MES-1 (0.340 ± 0.035) (P < 0.01), and between MES-1 and ≥ MES-2 (0.318 ± 0.037) (P < 0.01). The WLI scores for "vascular patterns" (r = -0.65, P < 0.01), "edema" (r = -0.62, P < 0.01), histology scores for "polymorphonuclear cells in the lamina propria" (r = -0.51, P < 0.01) and "crypt architectural irregularities" (r = -0.51, P < 0.01) showed correlation with the green color component of AFI. There were significant differences in green color components between limited (0.399 ± 0.042) and extensive (0.375 ± 0.044) (P = 0.014) polymorphonuclear cell infiltration within MES-0. As the severity of the mucosal inflammation increased, the green color component of AFI decreased. The AFI green color component was well correlated with the characteristic endoscopic and histological inflammatory features of UC. CONCLUSION: AFI has application in detecting inflammatory lesions, including microscopic activity in the colonic mucosa of UC patients, based on the green color component of images.

BACKGROUND AND AIM: The incidence of ischemic colitis (IC) in Japan has been increasing due to the westernization of diet and the aging population. The aim of this study was to evaluate the relationship between endoscopic findings and clinical severity in IC. METHODS: This retrospective analysis included 106 cases diagnosed with IC that were divided into two groups based on endoscopic findings in the acute stage: redness and erosion (RE) versus longitudinal and circumferential ulcers (LCU). The clinical variables were compared between the two groups. In addition, we investigated the risk factors of IC associated with the severity of the endoscopic findings by multivariate logistic regression analysis. RESULTS: The percentage of cases presenting abdominal pain was significantly higher in the LCU group than that in the RE group (p=0.002), as were the baseline serum CRP levels (p=0.0001). The periods of hospitalization in LCU group were longer than in the RE group (p=0.0001). Multivariate logistic regression analysis indicated that ischemic heart disease (IHD) and connective tissue disease were the independent explanatory factor associated with the endoscopic severity of IC (p<0.05). CONCLUSION: We showed clearly that the two endoscopic classifications were accurate indicators of severity and could be used to anticipate severity of IC. Furthermore, we confirmed that IHD and connective tissue disease were the exacerbating factor associated with the severity of endoscopic findings in IC.
