Background: Neutrophil to lymphocyte ratio (NLR) is a novel biomarker that has been recently studied in diverticulitis. The primary aim of this study was to assess the accuracy of NLR in predicting which patients had complicated diverticulitis and which patients required a radiological or surgical intervention. The accuracy of NLR was compared to C-reactive protein (CRP), white blood cell (WBC) count, neutrophil count and white cell to lymphocyte ratio (WLR). Methods: Details of all patients admitted with acute diverticulitis over an 18-month period were collected prospectively. Median CRP, WBC, neutrophil count, WLR and NLR values at initial presentation were compared using the Mann-Whitney U test. The diagnostic accuracy of each test was assessed using receiver operating characteristic curve analysis. Optimal cut-off points were determined for each biomarker using Youden's Index (J). Results: CRP, WBC, neutrophil count, WLR and NLR had variable accuracy in predicting complicated diverticulitis. NLR had the greatest accuracy of the 5 biomarkers in predicting the need for intervention with an area under the curve of 0.79 (p < 0.0001). The optimal cut-off point for NLR was 5.34 (J = 0.45). Conclusion: NLR was more accurate than CRP, WBC, neutrophil count and WLR in predicting the need for intervention. This cost-neutral, readily available biomarker can easily be calculated from the complete blood count and is a useful adjunct to CT.
In this relatively small series due to small population and low disease incidence, we have shown acceptable peri-operative course, morbidity and oncological outcomes with PC-RPLND compared to major international centres.
Cytoreductive surgery combined with intraperitoneal chemotherapy can improve survival in appropriately selected patients with colorectal peritoneal metastases. Outcomes are best in those patients in whom a complete cytoreduction can be achieved. Unresectable disease is however encountered in approximately one-quarter of patients at laparotomy. The merits, or otherwise, of proceeding with an incomplete cytoreduction in this setting are unclear. We performed a review of published outcomes following incomplete cytoreduction for colorectal peritoneal metastases. Using the electronic databases, PubMed and MEDLINE, a systematic search of available literature published during the period January 1997 to September 2014 was conducted. Following application of exclusion criteria, 19 papers were identified and included in this review. These comprised fifteen case series, 3 case control studies and one randomised control trial. In the nineteen studies included in this review, 2790 patients underwent cytoreductive surgery with or without intraperitoneal chemotherapy for peritoneal metastases of colorectal origin. Of these, 1732 (62%) underwent a complete cytoreduction while 986 (35%) patients underwent an incomplete cytoreduction. Median survival in the complete cytoreduction group ranged from 11 to 62 mo while survival in the latter group ranged from 2.4 to 32 mo. Of the 986 patients with an incomplete cytoreduction, 331 patients received intraperitoneal chemotherapy and survival in this cohort ranged from 4.5 to 32 mo. An incomplete cytoreduction, with or without intraperitoneal chemotherapy, does not appear to confer a survival benefit. The limited available data points to a palliative benefit in a subset of patients. In the absence of high quality data, the decision as to whether or not to proceed with surgery should be made on an individual patient basis.
SUMMARYGallstone ileus is a rare complication of cholelithiasis accounting for 1-4% of cases of intestinal obstruction with a predominance in the elderly population. Unfortunately, it has an insipid presentation and is associated with significant rates of morbidity and mortality. Controversy arises over the management of gallstone ileus, and while surgery remains the mainstay of treatment, the main point of contention surrounds the extent of surgery. We describe the case of an 85-yearold woman who presented with symptoms and signs of large bowel obstruction. Radiological evaluation revealed a 5 cm×3.5 cm gallstone impacted in the sigmoid colon. A laparoscopic-assisted enterolithotomy alone relieved the obstruction with minimal surgical insult and allowed for a swift and uneventful recovery. Our case emphasises the need for a high index of suspicion for the condition as well as highlighting the advantages of the use of laparoscopic surgery in an emergency setting. BACKGROUND
Cowden syndrome (CS) is a multi-system disease that carries an increased lifetime risk of developing certain cancers as well as benign neoplasms. The presence of features of CS in the general unaffected population results in difficulties in the recognition and diagnosis of this condition. Early diagnosis is essential to prevent the development of malignant neoplasms, yet despite the introduction of diagnostic criteria and risk calculators, accurate diagnosis remains a challenge. We identified three patients who presented to the symptomatic breast unit of a University Teaching Hospital over a period of 12 weeks who subsequently were diagnosed with CS. In this article, we discuss their clinical presentations as well as their path to diagnosis. The short timeframe between the presentations of these patients undoubtedly expedited their diagnosis. Upon application of internationally recognized diagnostic criteria, only two out of our three patients were accurately diagnosed. The risk of breast cancer in CS is comparable with that found in Hereditary Breast and Ovarian Cancer Syndrome and while a protocol for breast screening in these patients exists in most centres, no such protocol exists for patients with CS in our institution. The recommended cancer surveillance programs for patients with CS have not been found to prolong survival, however. CS consists of a vast array of diseases that span the various specialties and the subsequent varied phenotypic presentation poses diagnostic difficulties for clinicians as emphasized in our series. Continued research is required to improve recognition and diagnosis and will hopefully result in the emergence of life prolonging strategies.
