Résumé
Objective To explore the related factors of local reccurrence to rectal cancer after Dixon operation. Methods 100 patients with rectal cancer were used Dixon treatment. Then the tumor cells in the intestine and peritoneal fluid were qualitatively and quantitatively analyzed by flow cytometry during operation. The patients were followed up 2 years to understand the local recurrence. Results In 100 patients,8 cases were found in local recurrence after 2 years. 6 cases of recurrence were in the anastomotic site. Conclusion The local recurrence was related to Dukes stage,tumor distance from the anus,much margin of tumor length,tumor differentiation,intestine and abdominal shed close tumor cells,and it was worthy of attention.
Résumé
Objective To investigate the safety and therapeutic effect of modified laparoscopic Dixon surgery for mid-low rectal carcinoma. Methods From September 2004 to April 2007,26 patients with mid-low rectal carcinoma were selected to receive modified laparoscopic Dixon surgery.Through the anus,the rectum was pulled out,the tumor was removed,and then colon-rectum anastomosis was performed.Results All the operation was completed successfully.The average operation time was(166.3 ? 48.1) min,and the mean blood loss was(235.4 ? 124.7) ml.No patient had urethral injury,dysuria,anastomotic leakage,or other complications after the operation.The patients expelled gas(2.9?0.7) days after the operation.Their mean hospital stay was(8.8?1.4) days.During a follow-up of 15.7 months(6 to 27 months),3 patients had local recurrence,5 patients showed increased frequency of stool,and 18 had satisfied anal function.Conclusion The short-term results indicate that the modified laparoscopic Dixon surgery is safe and effective for mid-low rectal carcinoma,and is associated with minimal invasion.
