Predictive factors for colonic resection in patients less than 49 years with symptomatic diverticular disease.

BACKGROUND: Diverticular disease is a condition strongly associated with low-fiber intake and obesity. There have been reports of an increasing incidence in younger individuals ranging from 12% to 21% of all cases. The aim of this study was to evaluate the management of complicated diverticular disease in patients less than 49 years and attempt to identify factors predictive of a more virulent course. METHODS: An analysis of a prospectively updated database of all patients admitted with a primary diagnosis of acute diverticulitis from 2005 to 2013 was performed. Data collected included age, length of stay, inflammatory markers on admission, use of computed tomography (CT), and Hinchey Classification. SPSS version 22 was used for statistical analysis, and a P value of .05 or less was considered significant. RESULTS: A total of 120 (54 female and 66 male) patients less than 49 (28 to 49, 42.1) years were noted to have a diagnosis of acute diverticulitis. Twelve patients (10%) required colonic resection for complicated diverticulitis. Histological evaluation revealed 5 cases of stricture, 2 obstruction, and 5 perforations. On multivariate analysis, predictors of operative intervention and/or colonic resection included, (hazard ratio [95% confidence interval]) patients aged 40 to 49 years (.92 [.9 to .95]) and elevated C-reactive protein on index admission (1.4 [1.32 to 1.54]). Females were less likely to undergo colonic resection compared with males (1.18 [1.15 to 1.2]). Median length of stay was 4 days (1 to 48) for patients managed nonoperatively and 13 days (5 to 27) for those who underwent surgery. CONCLUSIONS: Most younger patients with acute diverticulitis can be treated successfully by conservative means. However, a proportion of patients require aggressive surgical management.

Spectrum of all-terrain vehicle injuries in adults: A case series and review of the literature.

INTRODUCTION: Serious injury secondary to all terrain vehicle usage has been widely reported since the 1970s. All-terrain vehicles (ATV) or 'quad bikes' are four wheeled vehicles used for agricultural work, recreation and adventure sport. Data collected in the U.S. indicates that ATV related injury and fatality is increasing annually. PRESENTATION OF CASES: This case series describes 3 cases of significant ATV related trauma in adults presenting to one regional hospital in the West of Ireland over a 12month period. DISCUSSION: Epidemiology, mechanisms of injury, spectrum of injury in adults and preventative measures to reduce the number of ATV related injuries and fatalities are discussed here with a review of the literature. CONCLUSION: A paucity of research outside of North America is highlighted by this case series. Mandatory reporting of ATV related injury, educational, training and legislative measures are suggested as injury prevention strategies.

Modern management of pyogenic hepatic abscess: a case series and review of the literature.

BACKGROUND: Pyogenic hepatic abscesses are relatively rare, though untreated are uniformly fatal. A recent paradigm shift in the management of liver abscesses, facilitated by advances in diagnostic and interventional radiology, has decreased mortality rates. The aim of this study was to review our experience in managing pyogenic liver abscess, review the literature in this field, and propose guidelines to aid in the current management of this complex disease. METHODS: Demographic and clinical details of all patients admitted to a single institution with liver abscess over a 5 year period were reviewed. Clinical presentation, aetiology, diagnostic work-up, treatment, morbidity and mortality data were collated. RESULTS: Over a 5 year period 11 patients presented to a single institution with pyogenic hepatic abscess (55% males, mean age 60.3 years). Common clinical features at presentation were non-specific constitutional symptoms and signs. Aetiology was predominantly gallstones (45%) or diverticular disease (27%). In addition to empiric antimicrobial therapy, all patients underwent radiologically guided percutaneous drainage of the liver abscess at diagnosis and only 2 patients required surgical intervention, including one 16-year old female who underwent hemi-hepatectomy for a complex and rare Actinomycotic abscess. There were no mortalities after minimum follow-up of one year. CONCLUSIONS: Pyogenic liver abscesses are uncommon, and mortality has decreased over the last two decades. Antimicrobial therapy and radiological intervention form the mainstay of modern treatment. Surgical intervention should be considered for patients with large, complex, septated or multiple abscesses, underlying disease or in whom percutaneous drainage has failed.

Radiolucent wooden foreign body masquerading as a depressed skull fracture.

The following case describes a head injury in an older male patient in which a large wooden foreign body, forming a subcutaneous tract in the scalp, was mistaken for a depressed skull fracture on initial clinical assessment. This foreign body was not visualised on CT brain imaging until specialised views were used retrospectively, after surgical exploration of the scalp laceration. Appropriate radiological techniques for the detection of radiolucent foreign bodies are discussed.

Bilateral adrenal haemorrhage secondary to intra-abdominal sepsis: a case report.

INTRODUCTION: Bilateral adrenal haemorrhage is a rare cause of adrenal failure. Clinical features are non-specific and therefore a high index of suspicion must be maintained in patients at risk. Predisposing factors include infection, malignancy and the post-operative state. CASE PRESENTATION: We report the case of a patient who underwent a left hemicolectomy with primary anastomosis and formation of a defunctioning loop ileostomy for an obstructing colon carcinoma at the splenic flexure. En-bloc splenectomy was performed to ensure an oncologic resection. The patient developed a purulent abdominal collection post-operatively and became septic with hypotension and pyrexia. This precipitated acute bilateral adrenal haemorrhage with consequent adrenal insufficiency. Clinical suspicion was confirmed by radiological findings and a co-syntropin test. Following drainage of the collection, antibiotic therapy and corticosteroid replacement, the patient made an excellent recovery. CONCLUSION: This case highlights the importance of prompt diagnosis and treatment of adrenal failure. In their absence, this condition can rapidly lead to death of the patient.

Scrotal metastases from colorectal carcinoma: a case report.

A 72-year-old man presented with a two month history of rectal bleeding. Colonoscopy demonstrated synchronous lesions at 3 cm and 40 cm with histological analysis confirming synchronous adenocarcinomata. He developed bilobar hepatic metastases while undergoing neoadjuvant chemoradiotherapy. Treatment was complicated by Fournier's gangrene of the right hemiscrotum which required surgical debridement. Eight months later he re-presented with an ulcerating lesion on the right hemiscrotum. An en-bloc resection of the ulcerating scrotal lesion and underlying testis was performed. Immunohistological analysis revealed metastatic adenocarcinoma of large bowel origin. Colorectal metastasis to the urogenital tract is rare and here we report a case of rectal carcinoma metastasizing to scrotal skin.
