Frydenberg HB 《Obesity surgery》1991,1(3):315-317
Many forms of gastric banding have been described and high reoperation rates reported. These can be mainly attributed to excess
vomiting associated both with and without stenosis. Reflux oesophagitis and the ‘sump’ effect may be other causes. This paper
examines the problems associated with banding leading to revisional surgery and introduces a new technique, ‘fundal supporting
suture’, to correct these problems. Preliminary results on 126 bandings without the modification and 22 with the modification
are presented. 相似文献

We studied the effect of the opiate antagonist naloxone on the human gastric acid secretory response to three secretory stimulants: sham feeding, pentagastrin, and histamine. Intravenous naloxone (40 g/kg/hr) significantly inhibited the acid secretory response to sham feeding without affecting the serum gastrin response to sham feeding. Naloxone also significantly reduced pentagastrin- and histamine-stimulated acid secretion. These studies indicate that naloxone reduces acid secretion in response to all stimulants of acid secretion yet tested in humans.This study was supported by grants AM-16816 and AM-17328, from the National Institute of Arthritis, Metabolism and Digestive Diseases.Presented in part at the Plenary Session of the American Gastroenterological Association, Salt Lake City, Utah, May 19, 1980. 相似文献

The somatizing patient 总被引:3,自引:0,他引:3
The authors discuss the significance of identifying primary care patients with dramatic and persistent unexplained physical (medical) symptoms, especially given the concerns about containing health care costs. Such patients are a cause of frustration to the clinician, because the clinician may experience a sense of failure after using the state of the art and still being eluded by a diagnosis. We focus on the methods for understanding somatic worry or preoccupation, which is the essential process in a variety of somatoform disorders. The second half of the article focuses on evaluation and treatment considerations and includes a discussion of both psychotherapeutic and psychopharmacologic treatment strategies for the somatizing patient. 相似文献

Abstract: This female Asian (Malay) baby had clinical features of Proteus syndrome. She had a large right facial lipolymphangioma with hyperpigmentation of the overlying skin. There was a smaller lymphangioma over the left side of her neck with excess nuchal folds, macrodactyly and bilateral talipes equinovarus. Despite the extensive hemifacial swelling, there was no evidence of upper respiratory tract obstruction. Generalized seizures developed on the sixth day of life which were controlled with phenobarbital. The lymphangiomas were excised without recurrence. 相似文献
