ABSTRACT
INTRODUCTION: Gastrointestinal Stromal Tumors (GISTs) are a rare slow growing malignancy, accounting for less than 1% of all gastrointestinal (GI) tract tumors. These tumors are usually discovered incidentally by endoscopy, surgery or radiology. However on occasions they may present with significant symptoms including GI blood loss. This case report discusses an atypical presentation of a GIST in a 57-year-old female. CASE PRESENTATION: A 57-year-old woman presented to the emergency department following one episode of melena. This occurred on a background of two previous presentations with melena over a 10-year period. She had a preceding surgery for a Meckel's Diverticulum. She was admitted for monitoring and investigation. An emergency upper endoscopy showed no upper gastrointestinal pathology to account for the bleeding. Her condition deteriorated with development of hypovolemic shock, requiring blood transfusion. An urgent CT angiogram identified a large mass in the distal ileum. The patient underwent an emergency laparotomy, where a 9.1â¯cm tumor located on the distal one-third of the ileum was resected. Histopathology confirmed the mass was a GIST. The patient had a successful post-operative period and subsequent treatment with Imatinib. DISCUSSION: The majority of GISTs are found incidentally. This case report describes an unusual presentation of a GIST in which the tumor bled into the intestinal lumen causing significant melena and life threatening hemorrhage. CONCLUSION: We conclude that GIST should be considered as a possible differential in rare cases of GI bleeding where more common causes have been ruled out.
ABSTRACT
PURPOSE: Iatrogenic bile duct injury (BDI) is the most significant associated complication to laparoscopic cholecystectomy (LC). Little is known about the evolution of the pattern of BDI in the era of laparoscopy. The aim of the study is to assess the pattern of post-LC BDIs managed in a tertiary referral centre. METHODS: Post-LC BDI referred over two decades were studied. Demographic data, type of BDI (classified using the Strasberg System), clinical symptoms, diagnostic investigations, timing of referral, post-referral management and morbidity were analysed. The pattern of injury, associated vascular injuries rate and their management were compared over two time periods (1992-2004,2005-2014). RESULTS: 78 BDIs were referred. During the second time period Strasberg A injuries decreased from 14% to 0 and Strasberg E1increased from 4% to 23%, the rate of associated vascular injury was six time higher (3.6% versus 22.7%), more patients had an attempted repair at the index hospital (16% versus 35%) sand fewer patients could be managed without surgical intervention at the referral hospital (28% versus 4%). CONCLUSION: Complexity of referred BDIs and rate of associated vascular injuries have increased over time. These findings led to more patients managed requiring surgical intervention at the referral hospital.

Retroileal colorectal anastomosis is an infrequently used technique providing tension-free anastomosis after extended left-sided colonic resection, which was first described by Turnbull in 1972. The authors describe the use of a retroileal colorectal anastomosis in a patient with chronic Candida albicans and Enterococcal retroperitoneal abscess. The patient's condition was most likely secondary to an anastomotic leak and colonic fistula post en bloc resection for recurrence of a left renal cell carcinoma. After failure of antimicrobial therapy and percutaneous drainage, surgical intervention was required. This involved resection of the existing colocolonic anastomosis and drainage of the retroperitoneal abscess. A retroileal colorectal anastomosis was then necessary to ensure a tension-free anastomosis. To the best of our knowledge, this is the first reported case of retroileal anastomosis used for this purpose. It highlights the importance of this technique in the surgeon's armamentarium.

In view of the ever-increasing HIV/AIDS epidemic in sub-Saharan Africa, the expansion of HIV-1 voluntary counselling and testing (VCT) as an integral part of prevention strategies and medical research is both a reality and an urgent need. As the availability of HIV-1 VCT grows two limitations need to be addressed, namely: low rates of HIV-1 serostatus disclosure to sexual partners and negative outcomes of serostatus disclosure. Results from a study among men, women and couples at an HIV-1 VCT clinic in Dar es Salaam, Tanzania are presented. The individual, relational and environmental factors that influence the decision to test for HIV-1 and to share test results with partners are described. The most salient barriers to HIV-1 testing and serostatus disclosure described by women include fear of partners' reaction, decision-making and communication patterns between partners, and partners' attitudes towards HIV-1 testing. Perception of personal risk for HIV-1 is the major factor driving women to overcome barriers to HIV-1 testing. The implications of findings for the promotion of HIV-1 VCT programmes, the implementation of partner notification policies and the development of post-test support services are discussed.
