The characteristics of patients and the endoscopic features of 196 patients with bleeding peptic ulcer in a multi-ethnic population were investigated. There was a male preponderance (M: F= 6.3: 1) and their mean age was 63.5 years. The prevalence of peptic ulcer bleeding in the Malays and Indians was similar to the ethnic distribution of population. However, the Chinese were over represented. Nearly 40% of patients studied had at least one co-existing medical illness. Hypertension and ischaemic heart disease were the most common diseases. History of non-steroidal anti-inflammatory drug usage was identified in 48% of the patients and it was the commonest risk factor associated with bleeding ulcers. More than 80% of bleeding ulcers were located in the duodenum and the pylorus. Endoscopic features of active bleeding or recent bleed were identified in more than 60% of the patients. The study notes that bleeding peptic ulcer is a serious and a potentially life threatening condition. It is a disease of the elderly and, with the steadily increasing elderly population in the country, the admissions rates of peptic ulcer bleeding is expected to rise. There is a need to plan for appropriate technical support, critical care facilities and expertise to avoid unacceptable outcomes.
Bleeding is a serious complication of peptic ulcer and mortality rate has remained at approximately 10% or more. Traditionally surgeons selected patients who were at significant risk of continued or re-bleeding and advocated early surgery. However, patients with bleeding peptic ulcers are generally elderly with coexisting medical illness and surgery results in significant morbidity and mortality. In the last decade, endoscopic haemostatic therapy has been effective in arresting the bleeding with surgical option considered only after endoscopic treatment has failed. We report the outcome of 196 patients who were endoscopically diagnosed to have bleeding from peptic ulcers. One hundred and thirty patients were to have active bleeding or recent bleed from the ulcer. Endoscopic adrenaline injection therapy was used in 53 patients who had active bleeding ulcers and another 77 patients with endoscopic evidence of recent bleed. The injection therapy was successfully in 127 (97.7%) patients. The treatment failed in three patients and they underwent urgent surgery. Re-bleeding occurred in 26 (20.5%) patients and endoscopic adrenaline therapy was repeated in these cases. Haemostatic was achieved in 19 patients, however 7 patients continued to bleed and required surgery. There were 3 deaths, principally from advanced age and coexisting medical illness. Endoscopic therapy for bleeding peptic ulcers is simply to apply, safe and effective. In cases of re-bleeding after initial endoscopic hemostasis, re-treatment is a preferable alternative to surgery. The role of surgery is limited to bleeding that is refractory or inaccessible to endoscopic control.
The hypercalcaemic crisis of hyperparathyroidism is an endocrine emergency that is invariably fatal if untreated. Despite emergency parathyroidectomies to treat hypercalcaemic crisis, mortality rates remain high. The rapid decline of serum calcium levels after removal of an adenoma and its adverse effect on the heart contributes to the development of postoperative complications and death. The cornerstone of surgical treatment for hypercalcaemic crisis is to begin infusion of high doses of calcium immediately after successful removal of parathyroid adenomas to allow gradual and well-controlled decline of serum calcium to avoid fatal myocardial complications.
Prebiopsy localization of impalpable breast lesions (IBL) assures removal of suspicious mammographically detected lesions. Specimen radiograph of the excised specimen is mandatory to confirm complete excision. The aim of this study was to audit our series of percutaneous hookwire localization and to determine the positive biopsy rate of the mammographically detected impalpable breast lesion in our center. Thirty-eight patients with suspicious IBL underwent excision biopsy under mammographic localization in our unit from late February 1998 to May 2003. The excised specimen is immobilized and compressed within the Transpec device. This device incorporates a reference grid visible in the specimen radiograph. Hence, the target lesion marked in the reference grid of the specimen radiograph will allow precise examination and exact localization of the suspicious lesion by the pathologist. The positive biopsy rate for malignant lesion was 26.3%, the majority fall in the range of 40-59 age group. Thirty-two (84.2%) of the patients had clustered micro-calcifications, 4 (10.5%) had impalpable mass lesions and in 2 (5.3%) spiculated lesions were seen on the preoperative mammogram. Mammographic feature of clustered micro-calcification accounts for all the malignant lesions in our series. Utilization of Transpec device has shown to be practical, reliable and cost effective in the management of IBL. Nonetheless, it should be emphasized that optimal specimen radiography and pathological correlation requires close cooperation between radiologist, surgeon and pathologist.
