ABSTRACT
INTRODUCTION: Ileal pouch-anal anastomosis (IPAA) is currently the gold standard for restoration of gastrointestinal continuity after colectomy for ulcerative colitis in the UK. However, with further experience of the risks relating to IPAA, the use of ileorectal anastomosis (IRA) is being revisited. Decisions regarding restorative surgery after colectomy are individual to every patient's circumstances, and this paper aims to provide a comprehensive review of the literature to guide a full discussion of the risks and benefits of IRA. METHODS: A systematic literature review was conducted of papers published from 2000 onwards relating to IRA and ulcerative colitis, in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. The papers were reviewed by two independent surgeons for information it was felt that patients and surgeons would want to know about the operation (cancer risk, bowel function, sexual and urinary function, fecundity/fertility and postoperative complications). RESULTS: Seventeen papers were identified for inclusion as they reported original data on one or more of the categories identified for discussion. The median ten-year cancer risk after IRA was 2.8% and the median failure rate at ten years was 21%. IRA was generally found to have lower postoperative complication rates and better bowel function than IPAA, with sexual function similar and fecundity not commented on in any paper. CONCLUSIONS: For some patients, IRA can offer restorative surgery in the short or long term, with acceptable cancer risk, failure rate and postoperative complications, while avoiding the higher risks associated with IPAA.
ABSTRACT
INTRODUCTION: McKittrick-Wheelock syndrome describes the condition of extreme electrolyte and fluid depletion caused by large distal colorectal tumours, usually the benign villous adenoma. Patients generally present critically unwell with severe hyponatraemia, hypokalaemia and/or acute kidney injury. METHODS: A structured literature review was undertaken to discover what is known about this condition, which is almost universally described as rare. Important features of the syndrome were identified, including common presenting symptoms, blood results, tumour location and size. FINDINGS: Our literature search identified 257 cases reported across all languages. The most remarkable features were the long duration of symptoms (median 24 months) and the significant electrolyte derangements (median sodium of 122mmol/l and median potassium of 2.7mmol/l at initial presentation). Five key recommendations are made to improve diagnosis, including aggressive fluid resuscitation to match rectal losses and surgical intervention on the index admission. The advantages and disadvantages of different treatment options are discussed, including minimally invasive alternatives to traditional resectional surgery. CONCLUSIONS: McKittrick-Wheelock syndrome describes a normally benign condition that can cause patients to become critically unwell and so it behoves all clinicians to be aware of it. By publishing recommendations based on a comprehensive literature review, we aim to improve diagnosis and management of this life threatening condition.
ABSTRACT
PURPOSE: In 2011 the local clinical commissioning group introduced a policy restricting funding for elective hernia repairs. Anecdotally, it was felt that this resulted in an increased number of emergency hernia repairs in our trust. Our primary objective was to assess whether this was actually the case. Our secondary objective was to quantify the risks of non-elective hernia repair. METHODS: We performed a retrospective cohort study, analysing all hernia surgeries performed between 2010 and 2013. The data were obtained from the trust Patient Information System. A total of 2556 patients underwent repair of inguinal, umbilical, incisional, femoral or ventral hernias over this time. RESULTS: As the policy intended, the number of elective hernia repairs reduced from 857 over 12 months before the funding restrictions to 606 in the same period afterwards (p < 0.001). Over the same time period, however, a significant rise in total emergency hernia repairs was demonstrated, increasing from 98 to 150 (p < 0.001). 30-day readmission rates also increased from 5.1 % before the policy introduction to 8.5 % afterwards (p = 0.006). In our data, the rate of bowel resection rises from 0.97 to 12.9 % for emergency operation compared to elective hernia repair (p < 0.001), while the median length of stay rises from less than 24 h to 3 days. CONCLUSIONS: Our data suggest that the funding restrictions introduced in 2011 were followed by a statistically significant and unintended increase in emergency hernia repairs in our trust, with associated increased risks to patient safety.
