RESUMEN
BACKGROUND: Peptic ulcer perforation is a common cause of emergency admission and surgery. This is the first study that documents the presentation and outcome of management in Irrua, Nigeria. PATIENTS AND METHOD: This is a prospective study of all patients operated on for perforated peptic ulcer between April 1, 2010, and March 31, 2015. A structured questionnaire containing patients' demographics, operation findings, and outcome was filled upon discharge or death. RESULTS: There were 104 patients. 81 males and 23 females (M : F = 3.5 : 1). The age range was between 17 years and 95 years. The mean age was 48.99 years ± SD 16.1 years. The ratio of gastric to duodenal perforation was 1.88 : 1. Perforation was the first sign of peptic ulcer disease in 62 (59.6%). Pneumoperitoneum was detectable with plain radiographs in 95 (91%) patients. 72 (69.2%) had Graham's Omentopexy. Death rate was 17.3%. CONCLUSION: We note that gastric perforation is a far commoner disease in our environment. Perforation is often the first sign of peptic ulcer disease. We identify fasting amongst Christians as a risk factor for perforation.
RESUMEN
Renal oncocytomas (RO) are tumours containing a population of cells with highly differentiated eosinophilic granular cytoplasm, extremely rich in mitochondria. It is estimated they account for about 3 to 7% of all solid renocortical tumours that were previously regarded as renal cell carcinoma. Based on their clinical behaviour and distinct pathologic features they are now regarded as benign renal tumours, often less than 5cm in diameter. We present a case of giant renal oncocytoma in a patient with synchronous bladder tumour, with pre-operative clinical, urographic and ultrasound features of locally advanced renal cell carcinoma (RCC). Findings at surgery included huge right renal tumour with infiltration to the duodenum; hepatic colic flexure; gall bladder; liver capsule and the greater omentum with small indurations at the base of the bladder. There was no tumour extension to the renal vein, no peritoneal seedling, no nodal metastasis and no ascites. Radical nephrectomy was carried out with good prognosis and without recurrence 52months post nephrectomy. This presentation, besides highlighting the possible giant nature of RO, also illustrates the malignant potential of RO to infiltrate contiguous structures and mimics infiltrating RCC. In view of the difficulties at establishing pre-operative diagnosis in this disease and because nephron-sparing surgery is curative, especially for the well-circumscribed tumours, RO should be considered in the management of patients with features of infiltrating RCC. A review of literature is also presented.
