Background: Stomal stenosis (SS) and marginal ulcer (MU) are reported to occur in 9-20% and 2-13%, respectively, of patients
undergoing gastric bypass for morbid obesity. It is hypothesized that decreasing tension on the gastrojejunostomy by performing
limited small bowel resection (SBR) would decrease ischemia, thereby decreasing the likelihood of SS and MU. Methods: A retrospective
review of 150 consecutive gastric bypass patients operated by one surgeon from 1993 to 1996 was performed. The incidence of
SS and MU was compared in patients with and without SBR. Results: The overall rate of SS was 24.0% and that of MU was 9.3%:
the incidence of both was 2.0%. The incidence of SS in patients without SBR was 26.9% and with SBR was 19.6%. The incidence
of MU in patients without SBR was 8.9% and with SBR was 9.8%. Neither result was statistically significant by Fisher's exact
test. Conclusion: There is a trend towards a decrease in the incidence of SS in gastric bypass patients with concomitant SBR
although this did not reach clinical significance. 相似文献

Global and regional cerebral blood flow (CBF) were evaluated with single photon emission computerized tomography (SPECT) utilizing both 133Xenon (133Xe) (47 subjects, 47–82 years old) and 99Tc-hexamethylpropyleneamine oxime (99Tc-HMPAO) (27 subjects, 47–80 years old). The 133Xe results showed: among total subjects, no age-related decline in global CBF, but a significant regional decline in the occipital lobe (p < 0.05); among men, significant age-related declines in global, frontal, temporal, occipital and right hemisphere CBF (all p < 0.05); among women, no age-related decline in global or regional CBF. The 99Tc-HMPAO results showed no age-related decline in either global or regional perfusion among total subjects, men or women. These results suggest that age-related global and regional (including frontal lobe) CBF declines do not occur in healthy control subjects after the age of 45 years. However, gender differences in age-related CBF changes warrant further study. 相似文献

Extrinsic compression of the renal artery due to a fibromuscular band originating from the diaphragm was encountered in a 26-year-old patient who had systemic hypertension associated with stenosis and kinking of one of her renal arteries. After surgical decompression, the renal artery assumed a normal expansion with disappearance of hypertension. Six other cases of extrinsic compression of the renal artery have been found in the literature. Surgical treatment is mandatory in all cases because the mechanism that causes the lesion makes percutaneous transluminal angioplasty illusory. 相似文献

A rare case of jejunal carcinoma coexisting with adenoma, situated 120 cm distal to the ligament of Treitz in a 53 year old
male, is reported herein. We also review cases of adenoma and carcinoma in the jejunum and ileum from the Japanese literature,
and discuss the histogenesis of carcinoma of the jejunum and ileum. 相似文献
