RESUMO

INTRODUCTION: Colorectal cancer (CRC) is one of the major life-threatening complications in patients with Crohn's disease (CD). Previous studies of CD-associated CRC (CD-CRC) have involved only small numbers of patients, and no large series have been reported from Asia. The aim of this study was to clarify the prognosis and clinicopathological features of CD-CRC compared with sporadic CRC. METHODS: A large nationwide database was used to identify patients with CD-CRC (n = 233) and sporadic CRC (n = 129,783) over a 40-year period, from 1980 to 2020. Five-year overall survival (OS), recurrence-free survival (RFS), and clinicopathological characteristics were investigated. The prognosis of CD-CRC was further evaluated in groups divided by colon cancer and anorectal cancer (RC). Multivariable Cox regression analysis was used to adjust for confounding by unbalanced covariables. RESULTS: Compared with sporadic cases, patients with CD-CRC were younger; more often had RC, multiple lesions, and mucinous adenocarcinoma; and had lower R0 resection rates. Five-year OS was worse for CD-CRC than for sporadic CRC (53.99% vs 71.17%, P < 0.001). Multivariable Cox regression analysis revealed that CD was associated with significantly poorer survival (hazard ratio 2.36, 95% confidence interval: 1.54-3.62, P < 0.0001). Evaluation by tumor location showed significantly worse 5-year OS and RFS of CD-RC compared with sporadic RC. Recurrence was identified in 39.57% of CD-RC cases and was mostly local. DISCUSSION: Poor prognosis of CD-CRC is attributable primarily to RC and high local recurrence. Local control is indispensable to improving prognosis.

RESUMO

BACKGROUND: Central venous catheterization is recognized as a lifeline that is important for chemotherapy or nutritional support in pediatric patients with malignant disease and intestinal failure. This study analyzed the risk of infection with Broviac line use among these patients at a single Japanese center. METHODS: Two hundred and four Broviac lines were inserted in patients in the pediatric ward from January 2003 to October 2011. We analyzed the risk of catheter-related bloodstream infection (CR-BSI) using clinical characteristics including underlying disease, sepsis history, inserted situation, drug use, and laboratory data at the time of Broviac insertion or before CR-BSI. RESULTS: During the study period, data from a total of 15 lines were excluded because of missing blood culture data. In the remaining 189 Broviac lines, 52 lines developed CR-BSI. On univariate analysis, leukemia, infantile Crohn's disease, sepsis history before Broviac insertion, existence of a stoma opening, and immunosuppressant use before CR-BSI were risk factors for CR-BSI. On multivariate logistic regression analysis infantile Crohn's disease, sepsis history before Broviac insertion, and immunosuppressant use before CR-BSI were independently associated with CR-BSI (P = 0.015, P = 0.045, and P = 0.043, respectively). CONCLUSIONS: Infantile Crohn's disease carries a high risk for CR-BSI because of its pathological condition, the therapeutic drugs required, and surgical intervention.

RESUMO

Ileal J-pouch-anal anastomosis is a commonly accepted surgical treatment for patients with ulcerative colitis. However, making a J-pouch anal anastomosis can be difficult due to anatomical variations of patients. We experienced an informative case of ulcerative colitis in which the ileal pouch was damaged when it was pulled down into the anal canal because of a fatty short mesentery. To preserve intestinal consistency and functioning fecal continence, a modified H-pouch was converted from a damaged J-pouch and anastomosed to the dentate line. This operation achieved a satisfactory functional result and, we believe, presents an option for reconstructing ileal J-pouch-anal anastomosis.
