This article provides an overview of the pathophysiology, causes, investigations, and management of high-output enterostomy and enterocutaneous fistula. High-output stoma and enterocutaneous fistula can result in intestinal failure and this is often fatal if not managed properly. The management involves reducing fluid losses, providing nutrients with fluids, and treating the underlying cause and sepsis. A multidisciplinary approach is required for successful management of patients with high-output enterostomy and enterocutaneous fistula.

In-hospital mortality rate has not changed in the last decade. Patients with arterial mesenteric infarction or with NOMI are over three times more likely to die during the first hospital admission compared with those with venous mesenteric infarction.

BackgroundScreening programmes exist in many countries for colorectal cancer. In recent years, there has been a drive for a non-invasive screening marker of higher sensitivity and specificity. Stool-based pyruvate kinase isoenzyme M2 (M2-PK) is one such biomarker under investigation. The aim of this systematic review and meta-analysis is to determine the diagnostic accuracy, sensitivity and specificity of M2-PK as a screening tool in colorectal cancer.MethodsA literature search of Ovid Medline, EMBASE and Google Scholar was carried out. The search strategy was restricted to human subjects and studies published in English. Data on sensitivity and specificity were extracted and pooled. Statistical analysis was conducted using summary receiver operating characteristic (SROC) curve methodology.ResultsA total of eight studies were suitable for data synthesis and analysis. Our analysis showed a pooled sensitivity and specificity for M2-PK to be 79% (CI 73%–83%) and 80% (CI 73%–86%), respectively. The accuracy of M2-PK was 0.85(0.82–0.88).ConclusionFaecal M2-PK assay has a relatively good sensitivity and specificity and high accuracy for screening colorectal cancer.

An ostomy is a justified last-resort treatment option in selected individuals with severe, chronic constipation. Patients should be warned of the negative effects on health-related quality of life and the risk of complications. We advocate using an algorithm presented in this article.
