Patient-Reported Outcome After Ostomy Surgery for Chronic Constipation.

PURPOSE: The purpose of this study was to describe experiences of and evaluate psychosocial and health-related quality of life of individuals undergoing ostomy surgery for severe, chronic constipation. METHODS: A search of the local ostomy archive and the electronic hospital episode statistics database was performed in a large tertiary referral center. Study outcomes were evaluated retrospectively using clinical notes and prospectively via administration of the City of Hope Ostomy Quality of Life questionnaire, Medical Outcomes Study Short Form-36, Hospital Anxiety and Depression tool, and a specially designed ostomy-specific questionnaire. Questionnaires were mailed and returned via post. RESULTS: Twenty-four patients, with a median age of 44 years (interquartile range [IQR] = 31-56), who underwent ileostomy (n = 20) and colostomy (n = 4) over a 13-year period participated in the study. The vast majority of respondents (91%; n = 22) were female. Ten (41%) underwent laparoscopic surgery, 13 (54%) underwent open procedures, and 1 was converted from laparoscopic to open surgery. The mean length of stay (5.5 days vs 5.4 days) and the rate of complication did not differ between the 2 approaches. Fourteen patients (13 females, median age = 47.5 years; IQR = 23-70 years) responded to the postal questionnaires (58.3%). Adverse effects on health-related quality of life in the physical and social well-being domains were reported, and a further 86% of respondents reported psychological morbidity related to their ostomy. However, more than 70% were satisfied (median follow-up = 17 months; IQR = 0.16-8 years) with their quality of life despite a 20% reoperation rate. CONCLUSIONS: 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.

Management of Intestinal Failure: The High-Output Enterostomy and Enterocutaneous Fistula.

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.

A systematic review and meta-analysis of the diagnostic accuracy of pyruvate kinase M2 isoenzymatic assay in diagnosing colorectal cancer.

BACKGROUND: Screening 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. METHODS: A 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. RESULTS: A 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). CONCLUSION: Faecal M2-PK assay has a relatively good sensitivity and specificity and high accuracy for screening colorectal cancer.

Mesenteric Infarction: Clinical Outcomes After Restoration of Bowel Continuity.

INTRODUCTION: Patients who have a bowel resection for mesenteric infarction may require parenteral nutrition (PN). This study primarily aimed to determine the aetiological factors for a mesenteric infarction and the effects of restoring bowel continuity on the long-term PN requirements. METHODS: A retrospective review of data on patients treated for mesenteric infarction from 2000 to 2010. RESULTS: A total of 113 patients (61 women, median age 54 years) were identified. Seventy-four (65%) had a superior mesenteric artery thromboembolism, 25 (22%) had a superior mesenteric vein thrombosis, and 4 (3%) had superior mesenteric artery stricture or spasm. Patients younger than 60 years most commonly had a clotting abnormality (n = 23/46, 50%), whereas older patients had a cardiological risk factor (n = 11/17, 65%). All patients with a jejunostomy required long-term PN. Fifty-seven (49%) patients had restoration of bowel continuity (colon brought into circuit). After this, PN was stopped within 1 year in 20 (35%), within 2 years in 29 (50%) patients and within 5 years in 44 (77%) patients (P = 0.001). CONCLUSIONS: A thrombotic tendency is the main etiological factor in most patients younger than 60 years. An anastomosis of the remaining jejunum to the colon can allow PN to be stopped.

Outcome of gastro-oesophageal reflux-related respiratory manifestations after laparoscopic fundoplication.

AIMS: Patients with refractory respiratory symptoms related to gastro-oesophageal reflux disease (GORD) such as asthma and cough are being referred for laparoscopic fundoplication (LFP), as recommended by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES). However there are limited data regarding symptomatic response to fundoplication in this group of patients. METHOD: A 7 year retrospective review was performed to study the efficacy of LFP in the treatment of patients with respiratory manifestations of GORD. Patients were followed up from 4 to 6 weeks (short-term) to 6-12 months (long-term) post-operatively. RESULTS: Of 208 patients who underwent LFP, 73 (35%) patients were eligible for inclusion into the study. 55 (75%) patients had improved respiratory symptoms at short-term follow-up. At long-term follow-up, 7 of these patients had recurrence of respiratory symptoms, while 4 patients had improvement not initially apparent. No significant predictive factor for the success or failure of surgery was identified. 190 (91%) of 208 patients had symptomatic improvement in GORD at short-term follow-up. CONCLUSION: LFP is effective with the response rates over 75% in the control of respiratory manifestation of GORD, compared to over 91% response rate in the control GOR symptoms alone. More research is needed to identify factors to aid patient selection to improve response rate.
