External iliac vein aneurysm: a case report and review of the literature.

Iliac vein aneurysms are extremely rare, even amongst vein aneurysms. We discuss the case of a 26-year-old man with an external iliac vein aneurysm, likely secondary to iatrogenic vascular trauma in the neonatal period. It is the first reported case of an iliac vein aneurysm presenting with lower urinary tract symptoms. Attempts at endovenous management were unsuccessful and therefore the patient underwent open aneurysmectomy. A PubMed literature search revealed a total of nine case reports of iliac vein aneurysms published in English since 2011. We discuss the aetiology, presentation, investigation and management of iliac vein aneurysms and compare to our own case.

Laparoscopic Adjustable Gastric Band Slippage Rates Following Laparoscopic Gastric Band Insertion: a Single Centre Experience.

INTRODUCTION: Laparoscopic adjustable gastric bands (LAGB) are placed around the superior aspect of the stomach to aid weight loss and co-morbidity resolution in morbidly obese patients. Slippage of the LAGB from its original position to lower in the fundus of the stomach leads to gastric obstruction, and sometimes ischaemia or perforation, necessitating LAGB repositioning or removal. This study aimed to identify the incidence of LAGB slippage, as well as predisposing factors that may influence its development. METHODS: All LAGBs inserted at one centre, via a pars flaccida technique, by four Bariatric specialist consultants, were reviewed utilising a prospectively maintained Bariatric database, computer records and case notes review. RESULTS: Seven hundred nineteen LAGBs were inserted and 33 slips treated; however, only 22 slips had their LAGB inserted at our centre (local slip rate 3.1 %). Multivariate analysis demonstrated a significant association between LAGB slip and younger median age at LAGB insertion (41 years slip vs. 45 years non-slip; p = 0.027), higher median total excess weight loss (64 % slip vs. 36 % non-slip; p < 0.001) and higher mean excess weight loss per month (2.41 % slip vs. 1.00 % non-slip; p < 0.001). There was no significant effect by sex, BMI at insertion or band type. CONCLUSIONS: Band slips are associated with greater excess weight loss and younger age. Larger studies may be necessary to further elucidate the risk factors contributing to, and mechanisms of, band slippage.

Perforation as a rare presentation of gastric gastrointestinal stromal tumours: a case report and review of the literature.

INTRODUCTION: Gastrointestinal stromal tumours (GISTs) are the most common connective tissue neoplasms of the gastrointestinal tract, the most common clinical presentation of which is with abdominal pain or gastrointestinal bleeding. METHODS: We describe a case of a perforated gastric GIST as well as reviewing the relevant published literature. RESULTS: A 51-year-old woman presented to the acute assessment unit with a 1-day history of severe epigastric pain on a background of longstanding reflux symptoms. Radiological investigation demonstrated a perforated mass in the gastric antrum and the patient subsequently underwent an emergency distal gastrectomy. She recovered well postoperatively and was discharged home. Her condition remains stable six months following surgery. Histological analysis revealed the perforated lesion to be a GIST. A PubMed search suggests that this is the first English report to describe a perforated gastric GIST. Six further published reports (written in English or with an English abstract) describing the presentation of small bowel GISTs with perforation are reviewed. CONCLUSIONS: We present the first English report of a perforated gastric GIST. More common presentations include abdominal pain and gastrointestinal bleeding. Although rare, GISTs should be considered in the differential diagnoses of perforated gastrointestinal masses.
