RESUMO
INTRODUCTION: The inflammatory burden index (IBI) serves as a prognostic marker for several cancers. Here, we evaluated the predictive value of preoperative IBI associated with the surgical and oncological outcomes of patients with esophageal cancer (EC). METHODS: The IBI was formulated as C-reactive protein × neutrophil/lymphocyte. We retrospectively analyzed preoperative IBI of 147 EC patients receiving esophagectomy between 2008 and 2018. Cox proportional hazards models and multivariable logistic regression were employed to identify independent risk factors of surgical site infection and prognosis. RESULTS: Increased preoperative IBI significantly correlated with higher tumor stage. Patients with high IBI experienced shorter overall survival (p = 0.0002) and disease-free survival (p = 0.002) compared with those with low IBI. In the adjusted Cox proportional hazards regression models, increased IBI served as an independent prognostic factor for overall survival (hazard ratio, 3.56; 95% confidence interval, 1.79-7.34; p = 0.0003) and disease-free survival (hazard ratio, 3.03; 95% confidence interval, 1.60-5.92; p = 0.007). Multivariable analysis identified preoperative high IBI which served as an independent risk factor for overall surgical site infection (odds ratio, 2.53; 95% confidence interval, 1.00-6.38; p = 0.049). CONCLUSION: Preoperative IBI may serve as a useful predictor of prognosis and surgical site infection of patients with EC after esophagectomy.

BACKGROUND AND AIM: Colitis-associated intestinal cancer (CAC) can develop in patients with inflammatory bowel disease; however, the malignant grade of CAC may differ from that of sporadic colorectal cancer (CRC). Therefore, we compared histological findings distinct from cancer stage between CAC and sporadic CRC to evaluate the features of CAC. METHODS: We reviewed the clinical and histological data collected from a nationwide database in Japan between 1983 and 2020. Patient characteristics were compared to distinguish ulcerative colitis (UC), Crohn's disease (CD), and sporadic CRC. Comparisons were performed by using all collected data and propensity score-matched data. RESULTS: A total of 1077 patients with UC-CAC, 297 with CD-CAC, and 136 927 with sporadic CRC were included. Although the prevalence of well or moderately differentiated adenocarcinoma (Tub1 and Tub2) decreased according to tumor progression for all diseases (P < 0.01), the prevalence of other histological findings, including signet ring cell carcinoma, mucinous carcinoma, poorly differentiated adenocarcinoma, or squamous cell carcinoma, was significantly higher in CAC than in sporadic CRC. Based on propensity score-matched data for 982 patients with UC and 268 with CD, the prevalence of histological findings other than Tub1 and Tub2 was also significantly higher in those with CAC. At pT4, mucinous carcinoma occurred at a significantly higher rate in patients with CD (45/86 [52.3%]) than in those with sporadic CRC (13/88 [14.8%]) (P < 0.01). CONCLUSION: CAC, including early-stage CAC, has a higher malignant grade than sporadic CRC, and this difference increases in significance with tumor progression.

PURPOSE: To determine the methylation level of the miR-124 promoter in non-neoplastic rectal mucosa of patients with pediatric-onset ulcerative colitis (UC) to predict UC-associated colorectal cancer (UC-CRC). METHODS: Between 2005 and 2017, non-neoplastic rectal tissue specimens were collected from 86 patients with UC, including 13 patients with UC-CRC; cancer tissues were obtained from the latter group. The methylation status of the miR-124 promoter was quantified using bisulfite pyrosequencing and compared between pediatric- and adult-onset UC patients. RESULTS: Patients with pediatric-onset UC experienced a significantly shorter disease duration than those with adult-onset UC. The levels of miR-124 promoter methylation in non-neoplastic rectal mucosa were positively correlated with the age at the diagnosis and duration of UC. The rate of increase in miR-124 methylation was accelerated in patients with pediatric-onset UC compared to those with adult-onset UC. Furthermore, the miR-124 methylation levels in non-neoplastic rectal mucosa were significantly higher in patients with UC-CRC than in those with UC alone (P = 0.02). A receiver operating characteristic analysis revealed that miR-124 methylation in non-neoplastic tissue discriminated between patients with pediatric-onset UC with or without CRC. CONCLUSION: miR-124 methylation in non-neoplastic rectal mucosa may be a useful biomarker for identifying patients with pediatric-onset UC who face the highest risk of developing UC-CRC.

PURPOSE: To assess the severity of preoperative myopenia and myosteatosis in pediatric patients with inflammatory bowel disease (IBD) and examine their impact on postoperative complications. METHODS: The subjects of this retrospective study were 30 pediatric patients with IBD (22 with ulcerative colitis (UC) and 8 with Crohn's disease (CD)) and 67 age-matched controls. Preoperative body mass index (BMI), psoas muscle index (PMI), and intramuscular adipose tissue content were compared between the patient groups, to investigate their association with postoperative complications. RESULTS: BMI and PMI were significantly lower in the IBD patients than in the controls (p < 0.0001, p < 0.0001, respectively). CD was associated with significantly lower BMI and PMI (p = 0.01, p = 0.01, respectively) than UC. Intramuscular adipose tissue content was comparable between the IBD patients and the controls and between the UC and CD patients. There were no significant differences among the three indices in relation to the presence or absence of postoperative complications in patients with IBD. When limited to surgical site infection (SSI), only PMI was significantly lower in the patients with SSI than in those without SSI (p = 0.04). CONCLUSIONS: Although BMI and PMI were lower preoperatively in pediatric IBD patients than in controls, only myopenia seemed to affect the development of SSI.

A 78-year-old man presenting with a chief complaint of discomfort was found to have advanced gastric cancer invading pancreatic body, and with the metastasis of paraaortic lymph node(No. 16). After 3 courses of the S-1 plus oxaliplatin regimen, CT scan showed the disappearance of invasion to pancreatic body, and the No. 16 lymph node. Then total gastrectomy(D2+No. 19+No. 16a1+No. 16a2), Roux-en-Y reconstruction and cholecystectomy were undergoing. Histological assessment for treatment response showed Grade 1a, and we finally diagnosed gastric cancer: MU, Post, type 2, 30×20 mm, tub1>por1, ypT3, ypN1, ycM0, ypStage â ¡B. The postoperative course was uneventful, and the patient was discharged from the hospital on postoperative day 19. S-1 as adjuvant chemotherapy was performed for 12 months, and no recurrence was recognized for 5 years and 9 months after operation.

In our department, total neoadjuvant therapy(TNT), which is a combination of preoperative chemotherapy and preoperative chemoradiotherapy(nCRT), has been introduced for the purpose of local and systemic disease control for lower rectal cancer. For patients in whom a clinical complete response(cCR)was obtained by TNT, we avoid the surgery and preserve organs, and follow-up strictly under the informed consent(watch and wait). In addition, for patients with remarkably reduced primary lesions(near cCR)without lymphadenopathy after TNT, the option of omitting total mesorectal excision (TME)and performing organ preservation by local excision can be introduced. Here, we report a case in which near cCR was obtained by TNT and organ preservation was performed by local excision. A 67-year-old man with lower rectal cancer(AV 5 cm, 15 mm, type 2, cT2N0M0, cStage â )was referred to our department with a desire to preserve the anus. TNT with nCRTâCAPOX was performed, and near cCR was obtained. After that, full thickness local excision of the residual disease was performed by transanal minimally invasive surgery(TAMIS). The final pathological diagnosis was Rb, 0.7 mm, por2, ypT1a, ypPM0, ypDM0, ypRM0. No recurrence is recognized for 3 years and 10 months after the operation.

The watch and wait strategy(W&W)is optional non-operative management for lower advanced rectal cancer patients who have achieved clinical complete response(cCR)following neoadjuvant treatment. However, the clinical implication of surgical intervention for the primary lesion is not well elucidated when distant metastasis appears with complete remission of the primary lesion. We report a case of a 47-year-old-woman with lower rectal cancer presenting inguinal lymph node metastasis after total neoadjuvant therapy(TNT)and managed through W&W after achieving cCR following chemotherapy. TNT was performed as a preoperative treatment for lower advanced rectal cancer, cT3N2aM0, cStage â ¢b. Although the primary lesion and mesenteric lymph node metastasis completely disappeared, bilateral inguinal lymph node metastasis appeared immediately after TNT. The patient was treated with FOLFOX plus panitumumab for rectal cancer with RAS and BRAF wild-type. Four months after chemotherapy, the inguinal lymph node metastasis disappeared, and W&W was used for the management. She stayed alive without recurrence 1 year and 9 months after chemotherapy.

AIM: The clinical significance of the geriatric nutritional risk index (GNRI) in locally advanced rectal cancer (LARC) patients undergoing preoperative chemoradiotherapy (CRT) followed by curative surgery has not been comprehensively evaluated. METHODS: This retrospective study enrolled 93 LARC patients diagnosed with clinical lymph node metastasis. The GNRI formula was as follows: 1.489 × albumin (g/l) + 41.7 × current weight/ideal weight. Patients were categorized as GNRI low (GNRI < 104.25) or high (GNRI > 104.25) according to the receiver operating characteristic (ROC) curve for survival analysis. The impact of GNRI status on the prognostic outcomes of curative surgery for LARC was examined. RESULTS: There were 55 (59.14%) and 38 (40.86%) patients in the GNRI high and low groups, respectively. Of the investigated demographic factors, age, pathological tumor invasion, and presence of recurrence were significantly associated with the GNRI value. In Kaplan-Meier analysis, overall survival (OS) and disease-free survival (DFS) were significantly shorter in the GNRI low group (OS: p = 0.00020, DFS: p = 0.0044, log-rank test). Multivariate analysis using a Cox proportional hazards model showed that a low GNRI was an independent risk factor for poor OS (hazard ratio (HR) = 3.22; 95% confidence interval (CI), 1.37-8.23; p = 0.0068) and DFS (HR = 2.32; 95%CI = 1.15-4.79; p = 0.018). Although use of adjuvant therapy has no impact on prognosis (OS: p = 0.26, DFS: p = 0.29), low GNRI showed shorter OS and DFS in patients with pathological lymph node metastasis [ypN(+)] (OS: p = 0.033, DFS: p = 0.032, log-rank test). CONCLUSIONS: GNRI is a useful marker for LARC patients diagnosed with clinical lymph node metastasis and treated by preoperative CRT followed by curative surgery. GNRI is a useful tool to identify high risk of recurrence for improving the survival in LARC patients.

PURPOSE: Systemic inflammatory response influences cancer development and perioperative surgical stress can affect the survival of patients with colorectal cancer (CRC). We developed a system to cumulatively assess perioperative inflammatory response and compare the prognostic value of various cumulative inflammatory and nutritional markers in patients with CRC. METHODS: We assessed perioperative cumulative markers using the trapezoidal area method in 307 patients who underwent surgery for CRC and analyzed the results statistically. RESULTS: The cumulative lymphocyte to C-reactive protein (CRP) ratio (LCR) predicted survival more accurately than other well-established markers (sensitivity: 80.0%, specificity: 69.3%; area under the curve (AUC): 0.779; P < 0.001). A low cumulative LCR was correlated with factors associated with disease development, including undifferentiated histology, advanced T stage, lymph node metastasis, distant metastasis, and advanced TNM stage classification. A decreased cumulative LCR was an independent prognostic factor for both overall survival (OS) (Hazard Ratio (HR):5.21, 95% confidence interval [CI] 2.42-11.2; P < 0.0001) and disease-free survival (DFS) (HR: 1.88, 95% CI 1.07-3.31; P = 0.02), and its prognostic significance was verified in a different clinical setting. The cumulative LCR was correlated negatively with the intraoperative bleeding volume (P < 0.0001, R = -0.4). Combined analysis of cumulative and preoperative LCR could help stratify risk for the oncological outcomes of CRC patients. CONCLUSIONS: The findings of this study demonstrate the value of the cumulative LCR in the postoperative management of patients with CRC.

PURPOSE: We recently revealed the preoperative lymphocyte C-reactive protein ratio (LCR) to be a new marker for predicting various outcomes in malignancies. The aim of our present study was to clarify the potential utility of the preoperative LCR for predicting the perioperative risk and oncological outcome in esophageal cancer patients. METHODS: We analyzed the preoperative LCR from 153 esophageal cancer patients to clarify its clinical relevance. RESULTS: The preoperative LCR was significantly decreased in a stage-dependent manner, and a decreased preoperative LCR was significantly associated with the occurrence of postoperative surgical site infection. Esophageal cancer patients with a low LCR showed a poor outcome in both the overall survival and disease-free survival compared with those who had a high LCR. Multivariate analyses showed that a decreased LCR was an independent prognostic factor for both a poor overall survival and disease-free survival. A decreased preoperative LCR was an independent predictive factor for postoperative surgical site infection and significantly correlated with nutritional and inflammatory indicators. In addition, the LCR was useful for identifying esophageal cancer patients likely to have a poor outcome among patients with and without neoadjuvant chemotherapy. CONCLUSIONS: Assessing the preoperative LCR might help physicians identify populations at high risk for perioperative complication and oncological outcomes, and determine individualized perioperative therapeutic strategies.

OBJECTIVE: Patients with ulcerative colitis (UC) often develop arthropathy. The purpose of this study was to determine the frequency of and risk factors for arthropathy in patients with UC who underwent total colectomy which is the final radical treatment lead to remission. METHODS: Patients who underwent total colectomy from January 2007 to April 2016 were analyzed for the development of arthropathy. The type of arthropathy and risk factors for developing arthropathy were analyzed by clinical and endoscopic severity classification, extraintestinal manifestations (EIMs) and medical treatment. RESULTS: Total of 219 patients who underwent total colectomy with sufficient medical records were analyzed. Forty-eight cases (21.9%) had EIMs, and 40 cases (18.2%) developed arthropathy (57.0% polyarthropathy; 42.5% peripheral arthropathy). Multivariate analysis showed that severity of Matts classification grade 3 or 4 versus grade 1 or 2 (hazard ratio [HR] 2.31, 95% confidence interval [CI] 1.22-4.36, p < .05) and EIMs other than arthropathy (HR 3.29, 95% CI 1.43-7.58, p < .05) were risk factors for the development of arthropathy. CONCLUSION: This study showed that approximately one fifth of patients with UC who underwent total colectomy developed arthropathy. The risk factors for the development of arthropathy were preoperative endoscopic disease activity and EIMs.

BACKGROUND: Recurrent laryngeal nerve paralysis (RLNP) after thoracoscopic esophagectomy for esophageal cancer (EC) is known to be a major complication leading to poor quality of life. RLNP is mainly associated with surgical procedures performed near the RLN. Therefore, with focus on the region of the RLN, we used preoperative computed tomography to investigate the risk factors of RLNP in patients with EC undergoing thoracoscopic esophagectomy. METHODS: We retrospectively examined 77 EC patients who underwent thoracoscopic esophagectomy in the prone position at our department between January 2010 and December 2018. Bilateral cross-sectional areas (mm2) of the fatty tissue around the RLN at the level of the lower pole of the thyroid gland were measured on preoperative axial computed tomography (CT) images. Univariate and multivariate logistic regression analysis was used to evaluate the association between the incidence of RLNP and patient clinical factors, including the cross-sectional areas. RESULTS: RLNP occurred in 24 of 77 patients (31.2%). The incidence of RLNP was significantly more frequent on the left side than on the right. (26% vs. 5.2%, respectively). Univariate analysis identified the following left RLNP risk factors: intrathoracic operative time (> 235 min), and area around the RLN (> 174.3 mm2). Multivariate analysis found that the area around the RLN was an independent risk factor of left RLNP. CONCLUSION: An increased area around the RLN measured on an axial CT view at the level of the lower pole of the thyroid gland was a risk factor of RLNP in EC patients undergoing thoracoscopic esophagectomy in the prone position.

BACKGROUND: Although the etiology of pouchitis remains unknown, inflammatory cytokines are significantly associated with the pathogenesis of pouchitis. The cytokine responses that characterize inflammatory bowel diseases (IBD) are key pathogenic components of the disease. Although cytokine profiles in the colonic mucosa have been investigated in experimental colitis models or IBD patients, cytokine profiles in the ileal mucosa at colectomy have been rarely assessed. AIM: To assess the relationship between pouchitis and T helper (Th) cytokines in the ileal mucosa collected at the time of colectomy and pouch construction. METHODS: This retrospective study involved 68 consecutive patients from January 2004 to May 2011 who underwent ileal pouch-anal anastomosis for ulcerative colitis. Samples were obtained from the terminal ileum of resected specimens at time of total colectomy or subtotal colectomy. mRNA expression levels of Th cytokines (IFN-γ, IL-23A, IL-5, IL-13 and IL-17A) were determined. RESULTS: Forty of 68 patients (58.8%) developed pouchitis. There was no association between IL-23A expression levels and incidence of pouchitis (p = 0.301). Patients with elevated IFN-γ had a significantly higher incidence of pouchitis compared with low IFN-γ patients (p = 0.043). Univariate analysis demonstrated a total dose of prednisolone > 7000 mg administered before colectomy (p = 0.04) and high IFN-γ expression (p = 0.02) were significant risk factors for pouchitis onset. In multivariate analysis, elevated IFN-γ messenger(m)RNA levels were significantly associated with pouchitis onset (p = 0.03). CONCLUSION: IFN-γ expression in the normal ileal mucosa at the time of colectomy may be an important factor in the pathophysiology of pouchitis.

BACKGROUND: The aim of the present study was to investigate the efficacy and safety of double-balloon enteroscopy (DBE) in postoperative pediatric patients. METHODS: This was a retrospective analysis of pediatric patients 18 years and younger referred to Mie University Hospital. Twenty procedures in 11 children occurred postoperatively; 29 children (42 procedures) had not undergone surgery. RESULTS: Among postoperative patients, five DBE procedures were performed via the oral route, 12 via the anal route, and three via a stomal route. Among nonoperative patients, 14 DBE procedures were performed via the oral route and 28 via the anal route. Four postoperative patients and two nonoperative patients had difficult pleating via the transanal route because of adhesions or thickening of the intestinal wall resulting from inflammation (P = 0.02). Excluding patients with stenosis, the mean length of endoscopic insertion for transanal procedures was significantly shorter among postoperative patients than among nonoperative patients (73.6 cm vs 160.5 cm, P < 0.01). There were no major complications in either group. CONCLUSIONS: Insertion difficulty was encountered in postoperative pediatric patients. However, our findings indicate that DBE is a safe procedure in postoperative pediatric patients.

BACKGROUND: Our previous study identified methicillin-resistant Staphylococcus aureus (MRSA) colonization as an independent risk factor for neonatal surgical site infection. Here we introduce intraoral breast milk application (IBMA) during a fasting state to prevent MRSA colonization. We aimed to evaluate both the risk factors for MRSA colonization and the efficacy of IBMA in neonatal surgical patients. METHODS: A retrospective review was performed using admission data from 2007 to 2016. Neonatal patients who underwent surgery and were tested periodically for MRSA colonization were evaluated for an association between MRSA colonization and perinatal or perioperative factors. RESULTS: The overall incidence of MRSA colonization for the 159 patients enrolled in this study was 16.4%. Univariate analysis showed that MRSA colonization was significantly more frequent in the following patients: those with Down syndrome, those admitted on their day of birth, those in need of fasting immediately after birth, and those not receiving IBMA. Multivariate analysis showed that comorbid Down syndrome was an independent risk factor (hazard ratio: 4.6; 95% confidence interval: 1.2-19.5, P = 0.03) and implementation of IBMA was an independent preventive factor for MRSA colonization (hazard ratio: 0.4; 95% confidence interval: 0.1-0.9, P = 0.04). MRSA-positive patients admitted significantly earlier and stayed longer preoperatively than MRSA-negative patients. CONCLUSIONS: In neonates undergoing surgery, and patients with Down syndrome, early diagnosis after birth and a long waiting period before operation may be associated with MRSA colonization. Intraoral breast milk application may be beneficial for preventing MRSA colonization.

PURPOSE: Gastric cancer (GC) is a common malignancy, especially in East Asian countries. There is emerging evidence that circulating neutrophil and platelet levels correlate with cancer progression. We evaluated the short- and long-term outcomes of GC patients systemically, to compare the original neutrophil-platelet score (NPS) and our modified NPS (mNPS). METHODS: We analyzed the original pre-operative NPS and the mNPS of 621 GC patients. RESULTS: Racial differences between the United Kingdom and East Asian countries accounted for compelling deviation in classification using the original NPS, which could not reliably stratify the prognoses of Japanese GC patients. We developed the mNPS using appropriate cutoff levels for pre-operative neutrophils and platelets, and demonstrated that the pre-operative mNPS was significantly correlated with all of the well-established clinicopathological factors for disease development, including advanced T stage, venous and lymphatic vessel invasion, lymph node/peritoneal /distant metastasis, and tumor-node-metastasis stage. The pre-operative mNPS could stratify prognostication for both overall survival (OS) and disease-free survival (DFS): a high pre-operative mNPS was an independent prognostic factor for the OS and DFS of GC patients and also an independent predictor of post-operative surgical site infection after gastrectomy. CONCLUSION: Calculating the mNPS could help clinicians to stratify the surgical and oncological risks of patients with GC.

BACKGROUND: The purpose of this study is to identify perioperative marker predicting postoperative surgical site infection (SSI) including with anastomotic leakage (AL) in curative colon cancer patients, laparoscopically. METHODS: In total, 135 colon cancer patients (stage I-III) undergoing curative laparoscopic surgery between January 2004 and December 2013 were enrolled in this study. We collected data on clinicopathological factors, laboratory data on pre and postoperative day 3 (POD3) and tumor markers levels to assess the relation to surgical site infection (SSI) including with anastomotic leakage (AL). RESULTS: SSI and AL occurred in 16 cases (5.6%) and 4 cases (3%), respectively. SSI and AL were not association with clinicopathological factors. Within laboratory data and tumor markers preoperatively, high neutrophil counts were significantly associated with SSI (P < 0.05) and AL (P < 0.01), respectively. Area under curves (AUC) of SSI and AL were 0.656 and 0.854, respectively. In addition, high neutrophil counts on POD3 also were significantly associated with SSI (P < 0.01) and AL (P < 0.01), respectively. Area under curves (AUC) of SSI and AL were 0.747 and 0.832, respectively. CONCLUSION: Neutrophil count on pre and POD3 are potentially valuable indicators of SSI including with AL in colon cancer patients undergoing curative surgery laparoscopically.

PURPOSE: Rac GTPase-activating protein 1 (RACGAP1) is associated with cell proliferation, and there is much evidence of its oncogenic role. This study investigated the clinical importance and functional role of RACGAP1 in esophageal carcinoma (EC). METHODS: A total of 81 EC patients were enrolled in the study. We assessed the immunohistochemical score of EC tissues and adjacent normal esophageal mucosae, and then performed multiple cell function tests by means of in vitro experiments to elucidate the functional role of RACGAP1 using RNA interference technology in EC cell lines. RESULTS: RACGAP1 was significantly overexpressed in EC tissues compared with the adjacent normal esophageal mucosae (p < 0.0001). Moreover, RACGAP1 overexpression was significantly correlated with poor overall survival (p = 0.032) and disease-free survival (p = 0.012) in EC patients. High RACGAP1 expression was also significantly correlated with the presence of lymphatic invasion (p = 0.012), vessel invasion (p = 0.003), and advanced TNM (tumor-node-metastasis) stage (p = 0.046) in EC patients. In vitro analysis demonstrated that RACGAP1 was involved in the proliferation, tumorigenicity, invasion, migration, and anoikis resistance in EC cells. CONCLUSIONS: RACGAP1 plays a pivotal role in EC development, suggesting that it could be used as an indicator of prognosis in EC patients.

BACKGROUND: The predictive factors for the development of pouchitis after ileal pouch-anal anastomosis (IPAA) in pediatric-onset ulcerative colitis (UC) have not been well investigated. The present study aimed to determine the predictive factors for the development of pouchitis after IPAA in the pediatric UC population. METHODS: The data from 54 patients with pediatric-onset UC who underwent IPAA in Mie University Hospital between 2000 and 2017 were retrospectively reviewed. A modified pouchitis disease activity index of ≥5 was defined as pouchitis. Potential preoperative, intraoperative, and postoperative predictors for pouchitis including various demographic and clinical variables were analyzed using Cox regression analysis, Students' t-tests, Mann-Whitney U tests, and Kaplan-Meier curves. The optimal cutoff value for continuous variables was determined using the receiver operating characteristic curve analysis. RESULTS: Pouchitis was identified in 17 (31.5%) patients within 5 y of follow-up. In multivariable analysis, the independent predictors for pouchitis were preoperative cumulative steroid dose of >10,000 mg (P = 0.0056) and >65% neutrophils just before IPAA (P = 0.032). Multivariate analysis revealed that the independent predictors of pouchitis were a total steroid dose of >10,000 mg (P = 0.0002) and a neutrophil percentage of >65% (P = 0.0078). No patient for whom both of these independent predictors were negative developed pouchitis, whereas >40% of patients who had one or both predictors developed pouchitis. CONCLUSIONS: In pediatric patients with UC, the predictive factors for pouchitis development are a greater cumulative total dose of steroids and a greater percentage of neutrophils before IPAA.
