Neutrophil: Lymphocyte ratio as a method of predicting complications following hepatic resection for colorectal liver metastasis.

BACKGROUND AND OBJECTIVES: Approximately 30-50% of patients with colorectal cancer develop liver metastasis for which liver resection is the only hope for potential cure. However, hepatic resection is associated with considerable morbidity. The aim was to detect early complications by utilising the neutrophil: lymphocyte ratio (NLR). METHODS: We performed a retrospective cohort study of patients undergoing hepatic resection at a single institution between 2008 and 2016. Baseline demographics and complications within 30 days following surgery were recorded, with blood tests measured until day 7. Statistical analysis was performed using Mann Whitney and ROC analysis. RESULTS: One hundred eighty-eight operations were included. 47.3% had an associated complication, of which 31.46% were major. The median NLR was 6.31 across the cohort, 5.44 for uncomplicated procedures, 7.0 for complications and 10.65 in major complications. Median NLR was the best parameter for detecting major complications versus minor complications (AUC 0.74) as opposed to lymphocytes (AUC 0.65), neutrophils (AUC 0.60), and CRP (AUC 0.60). The diagnostic ability of NLR increased further when predicting major complications versus an uncomplicated recovery (AUC 0.78), and it was the only significant parameter in the early post-operative period on days 2, 3, and 4 (AUC 0.70, 0.72, and 0.75). CONCLUSIONS: The NLR may have a role in predicting complications following hepatic resection for CLM, and with earlier detection, potentially improving outcomes.

A Global Survey by the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) on Perceptions of Bariatric Medical Tourism (BMT) by Health Professionals: Guidelines from IFSO for BMT.

BACKGROUND: Bariatric medical tourism (BMT) is a rapidly expanding industry, with over 650 million people with obesity worldwide and total number rising by over 300% between 2003 and 2014. The overall health tourism industry is worth over $400 billion/year. METHODS: International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) conducted a global survey to analyze the details of BMT and the perceptions of bariatric health care professionals (HCP) regarding BMT. RESULTS: A total of 383 bariatric HCP's with experience of 272,548 procedures responded from 65 countries. Seventy-three percent of respondents had managed BMT patients, whilst low cost of surgery was felt to be the driving factor in 77% of cases. The USA contributed the most patients travelling for BMT with 11.6%. Twenty-four percent of respondents stated that they had no access to adequate notes regarding the patient's operation, whilst 12% felt BMT is associated with a higher mortality. Only 49% of respondents felt that IFSO guidelines were followed by the operating surgeon. Sleeve gastrectomy was the commonly offered surgery and an overall mean operation cost was $8716. Nearly 64% of respondents felt BMT needed better coordination between practitioners, whilst almost 85% of respondents supported the idea of a forum to facilitate safe BMT worldwide. CONCLUSION: This IFSO survey has outlined the current BMT trends worldwide and highlighted areas of concern in the care of such patients. It has expanded our knowledge and should be used as a starting point to establish international forums to aid collaboration.

Predicting complications in hepatic resection for colorectal liver metastasis: the lymphocyte-to-monocyte ratio.

BACKGROUND: Colorectal cancer is one of the most common malignancies worldwide; whilst approximately 20% of patients have hepatic disease at presentation. Hepatic resection remains the gold standard of care; however, it is associated with significant morbidity. We sought to establish whether the lymphocyte-to-monocyte ratio (LMR) could help predict post-operative complications, thus improving patient outcomes. METHODS: We performed a retrospective cohort study of patients undergoing hepatic resection at a single centre. Baseline demographics and complications within 30 days following surgery were recorded. White blood cell counts and C-reactive protein (CRP) were recorded pre-operatively, and until post-operative day 7. RESULTS: A total of 188 operations were included. About 47.3% of resections had a complicated recovery, of which 31.46% were major. The median LMR was 1.29 across the cohort, 1.60 for uncomplicated procedures, 1.14 for those with complications and 0.85 in major complications. For detecting major complications versus an uncomplicated recovery, median LMR was the best parameter (area under the curve 0.78), whilst it was the only parameter to accurately predict such complications within 48 hours of surgery (area under the curve 0.72 on day 1). It was consistently the most accurate parameter at detecting uncomplicated versus complicated recovery, minor versus major complications, and major complications versus an uncomplicated recovery, at numerous timepoints over the post-operative period. CONCLUSION: The LMR appears better at predicting complications following hepatic resection for colorectal liver metastases, as opposed to conventionally measured parameters.

Intussuscepting Ampullary Adenoma: An Unusual Cause of Gastric Outlet Obstruction Leading to Cavitating Lung Lesions.

Ampullary adenomas are a rare clinical entity, occurring at a rate of 0.04-0.12% in the general population. They are premalignant lesions which have the capability to progress to malignancy, and they should be excised if they are causing immediate symptoms and/or are likely to degenerate to carcinoma. Intestinal intussusception in adults is rare and, unlike in children, is often due to a structural pathology. Intussuscepting duodenal/ampullary adenomas have been reported in the literature on 13 previous occasions, however never before with this presentation. We report the case of a woman who presented with a 1-year history of recurrent chest infections. She was treated with numerous antibiotics, whilst intermittent symptoms of recurrent vomiting and weight loss were initially attributed to her lung infections. A chest CT demonstrated multiple cavitating lung lesions, whilst an obstructing polypoid mass was noted at D2 on dedicated abdominal imaging. Due to ongoing nutritional problems, she had a semi-urgent pancreaticoduodenectomy. Intraoperative findings demonstrated a large mass at D2 with a duodeno-duodenal intussusception. Histological analysis reported a duodenal, ampullary, low-grade tubular adenoma, 75 × 28 × 30 mm in size, with intussusception and complete resection margins. The patient recovered well and was discharged on postoperative day 10, with no complications to date. Ampullary adenomas may present with obstruction of the main gastrointestinal tract and/or biliary/pancreatic ducts. Common presentations include gastric outlet obstruction, gastrointestinal bleeding or acute pancreatitis. This unique presentation should remind clinicians of the need to investigate recurrent chest infections for a possible gastrointestinal cause.
