Objective To assess the feasibility and adequacy of Harmonic Scalpel in a totally laparoscopic total mesorectal excision (TME) and low,ultralow,colo-anal anastomoses for rectal cancer. Methods Excision of the mesorectum and low，ultralow site anastomoses were performed laparoscopically on 30 patients with low rectal cancer based on the concept of TME. Results All 30 TME were successfully completed by laparoscopic approach, and no one was converted to open procedures. A cholecystectomy and/or an ovariotomy were meanwhile performed laparoscopically for 3 patients with rectal cancer,and 1 patient with chronic cholesyctitis, gallstone,ovarian cyst and torsion of the ovary. The operation time was 155 min (115-320 min). Operative blood loss was 20 ml (5-80 ml).The time of bowel function returned and the time to resume postoperative diet was 1-2 days after the operation. Fourteen patients had postoperative analgesic requirement. Average hospital stay was 8 days (5-14 days) and there were no intraoperative and postoperative complications in all 30 patients.Conclusion Laparoscopic excision of the mesorectum and low,ultralow,coloanal anastomoses with Harmonic Scalpel for low rectal cancer is a perspective minimally invasive technique, which is feasible, safe, effective and has dramatic high rates of sphincter preservation with decreased postoperative pain, rapid recovery.
Objective To introduce the total mesorectal excision (TME)under the laparoscope and with the ultrosonic scalpel. Methods Under the laparoscope and with the ultrosonic scalpel, total mesorectal excision in 3 patients was performed. In operation, alone the parietal layer of pelvic fascia and inside the automatic nerve trunk, the mesorectum was excised with the ultrasonic scalpel. Results Three patients got final recovery, no damage to the viscera in operation occurred. Average hemorrhage amount was about 100ml. Intestinal function recovered within 24 hours, average in hospital time was 10.3 days. After 4 months, 3 patients got good living quality without recurrence and metastasis.Conclusion TME under the laparoscope is a new progress of less damageable operation. Compared with the traditional open laparotomy,it has some advantage. But it requires high technology and expensive equipments, and the case is still very limited in use.

Objective To investigate the application of air leak test combined with methylene blue solution leak test in the detection of anastomotic leakage after total mesorectal excision （TME） in rectal cancer. Methods In total of132 patients with rectal cancer underwent Dixon according to TME in our hospital from Mar. 2010 to Mar. 2013 were enrolled. All patients were randomly divided into air leak test group （n=65） and air leak＋methylene blue solution leak test group （n=67）. The intestinal anastomosis of patients in air leak test group were clamped at 2 cm from the upper endof bowel， then injecting 500 mL distilled water to pelvic， and placing 24# Foley catheter through the anus. The catheter balloon was injected with water to close anus， and then injected with 50 mL gas to find the anastomotic leakage where bubbles happened， and then repaired it. Patients of air leak＋methylene blue solution leak test group were treated with methylene blue solution test in addition. After sucking out of the distilled water in pelvic and gas in the rectum， 1 bottle of methylene blue solution （20 mg） and 50 mL saline were injected， observing the location where the methylene blue solutionleaking out and repaired it. Results Three cases （4.62%） of anastomotic leakage were found during operation in air leak test group， and 9 cases （13.85%） were found after operation. Of the 9 cases， 5 cases were cured with placement of adeq-uate drainage and symptomatic treatment， 3 cases were cured with anal patch， and 1 case was cured with transverse colon fistula and drainage. In total of 15 cases （22.39%） were found anastomotic leakage， 2 cases of them were found by air leak test and another 13 cases were found by methylene blue solution leak test during operation in air leak＋methylene bluesolution leak test group， but no one suffered anastomotic leakage after operation. Compared with air test group， detectionrate of anastomotic leakage during operation was higher （P＜0.05）， and incidence rate of anastomotic leakage after opera-tion was lower in air leak＋methylene blue solution leak test group （P＜0.05）. Conclusions Large anastomotic leakage can be found by using air leak test， and small and hidden leakage can be found by using methylene blue solution leak test， combination method of the two experiments is better. Repair can be performed effectively under direct vision.
Objective To evaluate the feasibility, safety, radicality, and short-term and mid-term clinical outcomes of laparoscopic total mesorectal excision （TME） in comparison with open procedure for the middle-lower rectal cancer. Methods From October 2005 to October 2008， 52 patients with middle-lower rectal cancer received laparoscopic TME （Dixon’operation） without preventive stoma， while 46 patients underwent conventional open TME （Dixon’operation） without preventive stoma. The operative procedures, clinicopathological data， and short-term and mid-term outcomes were collected and compared between the two groups. Results The other patients were successful in both groups in addition to 2 （3.8%） patients were converted to open procedure in laparoscopic TME group. There was no perioperative death in both groups. The intraoperative blood loss, the time for bowel movement retrieval （first flatus）， and the incision healing in laparoscopic TME group were better than that in open TME group （P＜0.05）. No significant differences were observed between two groups in anastomotic leakage and pulmonary infection （P＞0.05）. Comparison of specimen, no significant differences were observed between two groups in negative distal margin and circumferential resection margin, number of lymph nodes resected, distance of distal resection margin to the tumor （P＞0.05）. No significant differences were observed between two groups in cancer-related death, local recurrence, distant metastasis, and 3-year survival rate （P＞0.05）. Conclusions Laparoscopic TME for middle-low rectal cancer is a safe, feasible, and minimally invasive technique, and can achieve satisfactory oncological outcome, which provides similar short-term and mid-term outcome compared with the traditional open procedure.
Objective To evaluate the feasibility and clinical outcomes of laparoscopic total mesorectal excision (TME) in treating mid-low rectal cancer. Methods From March 2005 to July 2008, 74 patients with mid-low rectal cancer undergoing laparoscopic TME in Zhejiang Cancer Hospital were collected. The data of clinicopathologic parameters were analyzed. Results Laparoscopic TME was performed on 74 patients with mid-low rectal cancer. No operative death occurred in this group. No case was converted to open procedure. The mean operation time was 187 min. The mean operative blood loss was 90 ml. The mean postoperative hospital stay was 10 d. Bowel function was restored on 46 h after operation on average. The mean distance between tumor and the section edge was 3.1 cm. The average number of lymph node dissection was 19.7. The sphincter preservation rate was 97% in patients with tumor 6 cm above the anal verge. The follow-up times were 2-44 months, average 25 months. The incidence of complications was 9.5%. No tumor cell port site implantation or distant metastasis happened. One case was pelvic recurrence， no patient was dead.Conclusion Laparoscopic TME is a feasible, safe and minimally invasive technique for the patients with mid-low rectal cancer, achieving the principles of TME.
