Background: The aetiology of gastric outlet obstruction globally has evolved from benign to malignant causes, but there seem to be no recent data on the trends in Ghana. The aim was, therefore, to identify the current patterns in the aetiology of gastric outlet obstruction in the adult population in Ghana. Methodology: This was a retrospective review of all confirmed cases of gastric outlet obstruction in the last decade, spanning from June 2004 to May 2014, that were managed at the Korle Bu Teaching Hospital. Results: A total of 107 patients were managed for gastric outlet obstruction with a male to female ratio of 2.15:1 and most of the patients making 71.3% of cases belonged to the age range of 40 to 60 years. The predominant aetiology for gastric outlet obstruction was found to be gastric cancer (55.140%), followed by peptic ulcer disease (27.103%). Conclusion: The aetiology of gastric outlet obstruction in Ghana has evolved from benign to malignant causes, following current global trends. Gastric cancer is now the most important cause of gastric outlet obstruction in Ghana, followed by peptic ulcer disease which predominates as the commonest benign cause.

Objective: To determine the clinico-histopathologic variations and etiological factors associated with oral squamous cell carcinoma (OSCC). Methods: A descriptive cross-sectional hospital based study was conducted at the University of Nairobi Dental Hospital (UNDH) and Kenyatta National Hospital (KNH) between September 2008 and February 2009. Eighty-two (82) patients presenting with lesions confirmed as OSCC were evaluated for habits identified as risk factors such as tobacco use, alcohol use and betel quid chewing. Demographic features including age and gender as well as clinical parameters such as site of the primary lesion, tumour size and nodal involvement were documented. Incisional biopsies were performed for all patients to confirm the diagnosis and histopathological features noted. Results: The mean age of the patients was 58.49 (range = 14 to 90 years), with a male to female ratio of 1.6:1. Remarkably, 13.4% of the patients were aged 40 years and below. The peak incidence was found to have been in the 6th - 7th decades. Tobacco use was the main associated etiological factor (73.2%) followed by alcohol use (57.3%). Notably, 25.6% of the cases had no identifiable risk factor. The tongue was the most common site (35%) followed by the palate (22%) (p = 0.03). The least commonly affected site was the floor of the mouth (10%). The most common stage at presentation was stage IV (52.4%) and;the poorly differentiated OSCC was the most common histopathologic variant (48.8%) followed by the well differentiated (30.5%) and moderately differentiated OSCC (20.7%). Conclusion: In the present investigation it is evident that OSCC has a male predilection with a peak incidence in the 6th - 7th decades and most commonly manifests in the tongue at stage IV with the poorly differentiated subtype being the most common. Of the cases diagnosed 13.4% were aged 40 years and below.
