Diagnostic effectiveness of preoperative water-soluble contrast enema in colorectal perforation
Summary: Objective: To evaluate the diagnostic usefulness of performing a preoperative water-soluble contrast enema (WSCE) before emergency surgery for colorectal perforation. Methods: We retrospectively reviewed 68 consecutive patients who underwent a preoperative WSCE before emergency surgery for colorectal perforation during the period from January 2011 to December 2017. Clinical characteristics and inflammatory biomarkers were compared between patients with Hinchey IāII versus those with Hinchey IIIāIV. Results: WSCE leakage occurred in 27 of 68 patients (39.7%). Univariate analysis showed that the two groups (Hinchey IāII and Hinchey IIIāIV) significantly differed regarding age, perforation site, cause of perforation, American Society of Anesthesiologists grade, presence or absence of WSCE leakage, and white blood cell count. Multivariable analysis revealed that WSCE leakage was a predictor of Hinchey IIIāIV, with an odds ratio of greater than 24 (PĀ =Ā 0.002). The sensitivity and specificity of WSCE leakage for differentiating those with Hinchey IIIāIV from those with Hinchey IāII were 76.5% and 97.1%, respectively. Conclusions: This retrospective study indicates that preoperative WSCE before emergency surgery is a useful tool for predicting the presence of Hinchey IIIāIV in patients with colorectal perforation.

A Case of Long-term Recurrence-free Survival after Resection of Colon Cancer and Chest Wall Metastasis
Survival outcomes of appendiceal mucinous neoplasms by histological type and stage: Analysis of 266 cases in a multicenter collaborative retrospective clinical study
Abstract Aim Appendiceal mucinous neoplasms are rare, and thus the literature is sparse with regard to histological types, staging, and prognosis. In particular, it is unclear how longāterm outcome may differ between mucinous adenocarcinomas and other adenocarcinomas. In the present study, we aimed to investigate the histological types and stages of appendiceal neoplasms, and to evaluate the prognostic impacts of these factors in patients with mucinous adenocarcinomas and nonāmucinous adenocarcinomas. Methods Patients with appendiceal tumors diagnosed between 2007 and 2016 were retrospectively identified from the databases of 19 institutions in the Clinical Study Group of Osaka University, Colorectal Group. Results A total of 266 patients with appendiceal tumors were identified, of whom 130 had pathologically diagnosed adenocarcinomas, including 57 with mucinous adenocarcinomas and 73 with nonāmucinous adenocarcinomas. Fiveāyear overall survival (OS) rates were 64.5% for mucinous adenocarcinomas, and 49.0% for nonāmucinous adenocarcinomas. OS was significantly shorter among patients with nonāmucinous adenocarcinomas compared to mucinous adenocarcinomas. Among patients with mucinous adenocarcinomas, 5āyear OS rates were 53.6% for stage 0/I, 82.6% for II/III, and 48.4% for IV. Among patients with nonāmucinous adenocarcinomas, 5āyear OS rates were 90.9% for stage 0/I, 68.8% for II/III, and 7.1% for IV. Analysis of patients with stage IV disease revealed significantly shorter OS among patients with nonāmucinous adenocarcinomas compared to mucinous adenocarcinomas. Conclusion Our present findings showed a better prognosis in patients with mucinous adenocarcinomas compared to nonāmucinous adenocarcinomas. In this setting, Union for International Cancer Control staging was associated with prognosis for nonāmucinous adenocarcinomas, but not for mucinous adenocarcinomas
