Intussusception of the appendix is an uncommon condition, and the diagnosis is rarely made preoperatively. Making an accurate diagnosis before laparotomy is important in providing the optimal treatment for the patient. We present the clinical and endoscopic features of two cases of intussusception of the appendix and review the literature. Diagnosis was(More)
Pneumothorax was identified as a complication of endoscopic hernia repair in two patients with insufflation pressures of 15 mmHg and operating times exceeding 2 h. These patients also showed intraoperative perturbations in both oxygen saturation and end-tidal CO2 production. A prospective study was undertaken to determine whether similar complications would(More)
Acute appendicitis is still a difficult diagnosis to make. Reports place the rate of incorrect diagnosis--the rate of negative laparotomy--at 15 to 42 per cent. This study is a prospective analysis of barium enema (BE) examinations performed upon 101 patients who presented with a history accompanied by signs and symptoms suggestive of, but not clearly(More)
It is known that not all thin malignant melanomas have an excellent prognosis and that the specific features identifying the patients at risk of metastasis have not been fully elucidated. We have looked at thin malignant melanomas (less than 1.5 mm) in the East of Scotland that had proven metastasis and death, and compared the clinical and histological(More)
Faecal occult blood testing with Hemoccult is becoming popular as a means of detecting colorectal carcinoma or adenoma. In determining its diagnostic place, such testing must be evaluated in patients with colonic symptoms as well as in asymptomatic populations. False negative test results may be determined either by full colonic investigation of screened(More)
BACKGROUND The purpose of this study was to compare ambulatory laparoscopic cholecystectomy (LC) with overnight LC and to determine its safety and the factors which will predict its success. METHODS Ambulatory LC was defined as LC followed by less than a 12-h stay in the ambulatory surgery unit; overnight LC was defined as LC followed by a hospital(More)
Temporal bone studies in cat, monkey, and man demonstrate that the cell bodies of the primary vestibular neurons located in Scarpa's ganglion persist after labyrinthectomy. However, it is not known whether the centrally directed axon process of deafferented vestibular neurons survive or degenerate after labyrinthectomy. If the central axon were to persist,(More)
