The da Vinci surgical system, which is currently the most widely used telerobotic device, was approved by the Food and Drug Administration of the United States of America for clinical use in all abdominal operations in July 2000. The first da Vinci surgical system in China was installed in November 2005 at our institution. We herein report the first telerobotic-assisted laparoscopic abdominoperineal resection using the 3-arm da Vinci surgical system for low rectal cancer in Hong Kong and China, which was performed in August 2006. The operative time and blood loss were 240 min and 200 mL, respectively. There was no complication, and the patient was discharged on postoperative day five. An updated review of published literature on telerobotic-assisted colorectal surgery is included in this report, with special emphasis on its advantages and limitations.展开更多

One postoperative death occurred. Follow-up studies were performed in 35 patients who had been treated by PPPD or the standard Whipple's procedure; they were questioned carefully concerning clinical symptoms. Further studies were porformed in 20 patients with or without pylorus preservation (10 patients, respectively). Nutritional status and gastrointestinal digestive and absorptive functions were evaluated by detemination of serum components, gastric analysis, barium emptying time, D-xylose absorption test,14CO2 breath test, PABA, and other methods. The results demonstrated malnutrition and postgastrectomy syndromes in some patients after the standard Whipple' s procedure, but not in those with PPPD. The quality of life was better in the latter. Pylorus preservation may be the main reason for this above difference. Delayed gastric emptying in the early postoperative period was a complication in some patients(21%) treated by PPPD.We recommend PPPD for pancreatoduodenectomy.展开更多
