Summary This report describes the technique and results of endoscopic fistulotomy as a drainage procedure in cases of malignant obstruction of the biliary system from bulky and friable growths in the papilla of Vater. Fistulotomy, coupled with insertion of stents, was successful in seven of eight patients and was associated with relief of jaundice. It is suggested that the method be applied when conventional transpapillary insertion of stents is impossible either due to distortion of the papilla or bleeding of the growth on touch. 相似文献

应用放射免疫测定法,对20例胃肠癌患者进行了血清癌胚抗原(CEA)测定,并应用免疫组化法对其中16例癌组织中的CEA进行了检测.检测结果,血清CEA阳性6例,癌组织CEA阳性9例.低分化癌的血清CEA显著高于高分化癌(P<0.05).血清CEA与癌灶部位、癌组织CEA与分化程度及血清CEA均无关(P>0.05).提示血清CEA的含量与癌组织的分化程度有关,血清CEA与癌组织内的CEA无平行关系.作者并对其机制及检测CEA的意义进行讨论. 相似文献

The neuroleptic malignant syndrome (NMS) is a life-threatening complication of neuroleptic treatment. To elucidate the pathogenesis of NMS, an animal model has been developed. Experimental rabbits treated with haloperidol (1 mg/kg) by intramuscular injection, were studied for the diagnostic symptoms of increased muscle rigidity, elevated body temperature, and high serum creatine phosphokinase (CPK) level. Administration of haloperidol (1 mg/kg) and atropine (0.4 mg/kg), and exposure to high ambient temperature (35°C) induced a significant increase in electromyographic activity with muscle rigidity similar to that observed in patients with NMS. Such rabbits also showed elevated body temperature and serum CPK value. In addition to the similarity of the signs and symptoms, all parameters measured (muscle rigidity, body temperature, and serum CPK level) were normalized by dantrolene treatment. The effectiveness of dantrolene in the experimental animal partially confirms the validity of this animal model for NMS. This experimental animal model for NMS may be useful to elucidate the pathogenesis of NMS. 相似文献

The findings in twenty-two patients with insulinoma were reviewed, as continuous efforts should be made to establish preoperative
localization of the tumor. Superselective arteriography and percutaneous, transhepatic portal vein and pancreatic venous catheterization
are highly recommended approaches. At the time of surgical intervention, a cautious exploration of the pancreas after thorough
mobilization is most important. Recent use of intraoperative ultrasonography increases the likelihood of finding these occult
tumors which locate deeply in the head of the pancreas. Apart from the diagnostic problems, we wish to emphasize the high
incidence of malignancy (7/22, 31.8 per cent) in our series. Althout patients with malignant isulinoma had a much better prognosis
compared to those with a pancreatic ductal malignancy, pancreatic resection with regional lymphnode dissection seems to be
a rational procedure. Enucleation can be done when intraoperative findings of the tumor and regional lymphonode indicate no
malignant features and no multiple lesions. However, at the first operation, enucleation is still a procedure of choice, even
for the malignant insulinoma in the head with a well-defined capsule and no metastatic lesions, the objective being to avoid
a duodenopancreatectomy or total pancreatectomy.
These data were reported at the 30th Congress of Société Internationale de Chirurgie, Hamburg, Germany, 1983 相似文献

Radiation-induced bone tumors in beagle dogs exposed to 90Sr have been evaluated in terms of their incidence, time of appearance, occurrence as multiple tumors, anatomic distribution, and the influence of sex on their development. Among dogs fed 90Sr during skeletal development, the incidence of bone tumors was dose dependent. Tumors thus appeared in 10 of 19 dogs receiving average skeletal doses of 130 Gy, 15 of 60 receiving 97 Gy, 5 of 61 receiving 61 Gy, 2 of 65 receiving 26 Gy, and 1 of 40 receiving 1.3 Gy. No tumors appeared among 66 dogs who received 8 Gy, 78 who received 0.3 Gy, and 80 non-irradiated controls, all of which have been observed for life. Among dogs given a single intravenous injection of 90Sr in early adulthood, tumor production was somewhat higher than among 90Sr-fed dogs at the same radiation dose: bone tumors were present in 6 of 25 dogs who received 62 Gy and 1 of 20 dogs who received 7.5 Gy. Bone tumors appeared sooner and were more often multiple in animals receiving the higher doses. Long bones were the sites of most of the tumors appearing after the highest dose level. Bones of the head, particularly the mandible, were the predominant site of tumors in the next highest dose level group. 相似文献

Metachronous primary malignant tumors of uterine papillary serous carcinoma (UPSC) and non-Hodgkin's lymphoma (NHL) are rare. UPSC is a clinically aggressive and morphologically distinctive variant of endometrial carcinoma. We describe the clinical features of a 63-year-old patient with UPSC that was found 2 years after chemotherapy for malignant lymphoma of neck, stage IV and 5 months after radiation therapy for recurrence. This patient had undergone staging surgery and postoperative radiation for UPSC. One month after completion of radiotherapy, the patient expired due to persistence of the disease. The association between host immunity and UPSC is rarely described in the literature. Immunological profiles of this patient, with compositional changes of natural killer, B, and T cell, dramatically altered the percentage of CD4(+) T cell, CD8(+) T cell, and CD4/CD8 ratio, signifying depressed host immunity. Immunological profile of this patient stressed the issue of depressed host immunity and associated malignancies. 相似文献

The current report focuses on two patients of the same age who presented similar appearances on initial anteroposterior chest images. Follow-up images showed superoanterior and superoposterior mediastinal lesions. The first patient with noninvasive cystic thymoma was suspected before surgery, while the pathologic diagnosis was intrathoracic phrenic nerve schwannoma. The second patient was with an asymmetric, dumbbell-shaped paravertebral tumor over T3 and T4 on the left side. The preoperative… 相似文献

Retrospective review of the preoperative biliary and gastrointestinal evaluation for gastric bypass surgery 总被引:1,自引:0,他引:1
Vincent W. Vanek M.D. C.N.S.P. F.A.C.S. Michele Catania R.N. B.S.N. Kimberly Triveri R.D. L.D. Robert W. Woodruff Jr M.D. 《Surgery for obesity and related diseases》2006,2(1):839-22
BACKGROUND: The purpose of this study was to analyze the frequency and results of preoperative biliary and gastrointestinal (GI) evaluation of patients undergoing Roux-en-Y gastric bypass (RYGB). METHODS: Retrospective review of the preoperative evaluation of 144 consecutive RYGB patients. RESULTS: Cholecystectomy had already been performed in 43 (30%) patients; 22% of those patients with an intact gallbladder had cholelithiasis. Ten patients (7%) had an upper GI x-ray (UGI), and 94 patients (65%) had an esophagogastroduodenoscopy (EGD). Abnormalities were found in 40% of the UGIs and 84% of the EGDs. A total of 96 patients (67%) were tested for Helicobacter pylori; 11% were positive. Twenty-one patients (15%) underwent preoperative colonoscopy; 48% were abnormal, but most of the abnormalities were not clinically significant. Three patients had barium enema x-ray, which was normal in all cases. CONCLUSIONS: The preoperative biliary and GI evaluation of bariatric surgery patients should include a routine ultrasound of the gallbladder. Routine preoperative EGD will detect a significant number of abnormalities that should be treated, but should rarely alter the bariatric surgical procedure or result in denial of bariatric surgery. Many abnormalities will be asymptomatic. Patients should be routinely screened for H. pylori and, if positive, treated before bariatric surgery. Lower GI evaluation should be performed selectively based on the patient's symptoms, physical findings, and guidelines for colorectal cancer and polyp screening. 相似文献
