The surgical experience of the recurrent hepatolithiasis of 163 cases / 中国医师进修杂志

Objective To study the ways and effect of surgical treatment for recurrent hepatolithiasis. Methods The therapeutic patterns and the clinical effect were retrospectively analyzed for 163 patiens8 with recurrent hepatolithiasis from January 2004 to December 2006.The 86 patients were partical hepatectomy, the 77 patients were no hepatectomy. Results The excellent rate was 96.5%,the incidence of residual stone and recurrence was 5.8%and 1.2%respectively in partical hepatectomy-but 85.7%,15.6% and 11.7%in no hepatectomy. There were statistical significance between the partical hepatectomy and no hepatectomy(P＜0.05).Conclusion The therapeutic effect of the partial hepatectomy is better than that of the nohepatectomy for the patients with gallstone.

DISCRETE RADIOFREQUENCY CATHETER ABLATION FOR PAROXYSMAL ATRIAL FIBRILLATION IN A DOG MODEL / 解放军医学杂志

To investigate an approach of treatment for atrial fibrillation with discrete ablation lesion, 12 dogs with experimental atrial fibrillation underwent radiofrequency catheter ablation. Atrial lesion was made at the most vulnerable site. The results showed that in 10 of 12 dogs persistent fibrillation could be ablated. There was no significant change in sinus heart rate, P wave duration, and corrected sinoatrial node recovery time (cSNRT). The results suggested that paroxysmal atrial fibrillation could be eliminated by point ablation of the lesion, and that trigger activity might be involved in the mechanism of atrial fibrillation.

Clinical analysis on primary small intestinal tumor / 中国普通外科杂志

ObjectiveTo explore the clinical characteristics and diagnosis of primary small intestinal tumor (PSIT). MethodsRetrospective analysis of the clinical and pathological data of the 112 PSIT cases was made. ResultsDuodenum was the most common site for PSIT (62 5%). Leiomyomas were most common benign tumors which were most likely found in ileum and jejunum. Adenocarcinoma was the most frequently seen malignant PSIT followed by lymphoma and leiomyosacroma. The chief method of diagnosis is barium meal X ray examination especially with the hypotonic contrast X ray examination. Endoscopy can increase the diagnostic rate. Superior mesenteric arteriography sometimes helps in determing the site of gastrointestinal haemorrhage. CT scan can be helpful in establishing diagnosis, preoperative classification and postoperative recurrences. Conclusion Duodenal adenocarcinoma is most common PSIT, followed by malignant lymphoma, liomyoma and leiomyosarcoma. Hypotonic contrast X ray examination is most effective in diagnosis, and locating of small bowel tumors. Superior mesenteric artery angiography and CT scanning are also helpful.
