Experience of Da Vinci Robotics-Assisted Dixon Procedure for Rectal Cancer in 11 Cases

Objective　To summary the early experience of Dixon procedures with Da Vinci robotics surgical system for rectal cancer. Methods　Eleven patients with rectal cancer underwent the combination of laparoscope and Da Vinci robotics surgical system with 4 trocars in our hospital from May. 2011 to Jan. 2012. Laparoscopy was firstly used to identify the possibility of the surgical procedure， then placed the 4 trocars， and maked sure the suspension of the sigmoid colon and the uterus. Transections of rectum were performed by a conventional laparoscopic method， and endoscopic separations were performed by Da Vinci robotics surgical system. The clinical data were retrospectively analyzed and the experience was summarized. Results　The Da Vinci robotics-assisted Dixon procedures were successfully performed in 11 patients and no one turned to laparotomy. The operating time was 210-330min （mean 288.6min）；the blood loss was 20-100ml （mean 40ml）； The number of lymph nodes dissected was 12-21 per case （mean 13.9 per case）；the duration of bowel movement and hospital stay were 18-26h （mean 22h） and 7-16d （mean 11.5d）， respectively. There were no intraoperative or postoperative complications related to the use of robotics， and no residual cancer cells at resection margin. Conclusions　Da Vinci robotics-assisted Dixion procedure with 4 trocars and suspension of sigmoid colon are safe and feasible， and it is beneficial to the recovery of patients

Cause Analysis of Stoma Recurrence after Anterior Resection of Rectal Cancer (Report of 91 Cases)

ObjectiveTo investigate the cause of stoma recurrence after anterior resection of rectal cancer and discover the methods of prevention and treatment.MethodsA total 91 patients with stoma recurrence after anterior resection of rectal cancer (or Dixon) were analysed retrospectively between 1985 and 1996. Fourtyseven patients experienced reradical resection (Miles), 27 cases palliative resection, and 11 cases only exploration. Thirtytwo cases had been followed up for 5 years and obtained 1，3，5year survival rate for reradical radical resection (Miles). Diagnosis and treatment of stomal recurrence after Dixon were evaluated. ResultsOne, three and fiveyear survival rate of reradical resection (Miles) was 93%，77%，45% respectively.ConclusionTo amplify blindly the adaptation of Dixon is to raise the rate of stoma recurrence. Digital rectal examination and fiberopic colonoscopy (and biopsy) are very essential methods for the diagnosis of stoma recurrence, and we strive to do reradical resection (Miles) for the patients with stoma recurrence after Dixon’s operation.

Comparative Outcomes of Low/Ultra-Low Anterior Rectal Resection and Valgus Resection in Elder Patients with Rectal or Anal Cancer

Objective　To compare the outcomes of low/ultra-low anterior rectal resection and valgus resection in elder patients with rectal or anal cancer. Methods　The clinical data of 184 patients with rectal or anal cancer， who were treated with extreme sphincter preserving surgery in West China Hospital from January 2009 to December 2011， were collected and analyzed retrospectively. The intraoperative and postoperative indexes between low/ultra-low anterior rectal resection group and valgus resection group were compared. Results　①There were no significant differences in the age，body mass index， gender， diameter of tumor， TNM stage， degree of differentiation， histological type， gross type， and complications before operation， such as hypertension， chronic obstructive pulmonary disease， cardiovascular diseases， diabetes， renal disease， and hypoproteinemia in two groups （P＞0.05）. ②Compared with the low/ultra-low anterior rectal resection group， the distance from the anal verge to the tumor was shorter （P＜0.05） and the distance of distal resec-tion margin of tumor was longer （P＜0.05） in the valgus resection group. ③There were no significant differences in the operation time， blood loss， ASA grade， and the postoperative complications in two groups （P＞0.05）. ④There were no significant differences in the duration of pulling out nasogastric tube， urinary catheter， and drainage tube， the duration of first passing flatus， first defecation， first oral intake， and first ambulation， and hospitalization cost （P＞0.05）. But the postoperative hospital stay and total hospital stay in the valgus resection group were significantly longer than those in the low/ultra-low anterior rectal resection group （P＜0.05）. ⑤All the patients were followed-up for 6-24 months （average 13 months）. During the following-up， only 1 case suffered local tumor recurrence in the valgus resection group. One case suffered distant metastases in the ultra-low anterior rectal resection and valgus resection group， respectively. Eight cases （4.35%） died， of which 4 cases （4.04%） in the low/ultra-low anterior rectal group and 4 cases （4.71%） in the valgus resection group. All the patients were in functional recovery of anal control after operation. Conclusions　As the extreme sphincter preserving surgery for elder patients with rectal or anal cancer， the low or ultra-low anterior rectal resection and valgus resection could both be used for elder patients with extreme-low rectal or anal cancer. However， valgus resection results in longer distal surgical margin than that low/ultra-low anterior rectal resection， and it is suitable for the patients with shorter distances from the anal verge to the tumor.

目的 探讨盲肠管道式造口持续减压方法防治直肠癌低位前切除术后吻合口漏的临床价值。方法 选择120例拟行直肠癌低位前切除手术患者，按机械抽样法随机分成2组，60例为盲肠管道式造口减压组（盲肠减压组），另外60例行常规手术作为对照。分析2组患者术后吻合口漏、消化道反应、呼吸系统感染及腹腔感染发生的差异及出现吻合口漏后的住院时间、开始进食时间和住院总费用。结果 盲肠减压组与常规手术组相比，发生吻合口漏〔(5.0%（3例）比13.3%（8例）〕、消化道反应〔15.0%（9例）比48.3%（29例）〕、呼吸系统感染〔11.7%（7例）比26.7%（16例）〕及腹腔感染〔11.7%（7例）比21.7%（13例）〕者均明显减少(Plt;0.05)。盲肠减压组中发生吻合口漏的患者与常规手术组中发生吻合口漏的患者相比，漏后住院时间〔（39±3） d比（53±4） d〕更短，进食〔（14±2） d比（25±3） d〕更早，住院总费用〔（39 620±2 033）元比（46 750±2 131）元〕降低，差异均有统计学意义(Plt;0.05)。结论 盲肠管道式造口持续减压能有效降低直肠癌低位前切除术后吻合口漏的发生率。

Clinical Outcome of Fast-Track Surgery for Low/Super-Low Rectal Cancer

Objective To discuss the clinical outcome of fast-track surgery for low/super-low rectal cancer. Methods Between October 2007 and December 2008, 120 patients underwent low/super-low rectal cancer resection without formation of stoma in the West China Hospital were analyzed retrospectively. Postoperative early rehabilitations were compared between fast-track group and traditional group. Results In early rehabilitations, time of first passing flatus, ambulation, oral intake, and pulling out urinary catheter and the hospital stay in fast-track group were significantly earlier than those in traditional group （Plt;0.05）, while there was no significant difference in time of using nasogastric tubes or drains （Pgt;0.05）. There was also no significant difference in postoperative morbidity of complications between the 2 groups （Pgt;0.05）. Conclusion Fast-track surgery for low/super-low rectal cancer is safe and can accelerate recovery with decreased length of hospital stay.

Comparative Study of Large-Calibre Transanal Tube Usage after Rectal Cancer Anterior Resection for Prophylaxis of Anastomotic Leakage

Objective　To assess the effectiveness of large-calibre (7.5#) transanal tube drainage and decompression on prevention from anastomotic leakage following anterior resection for rectal cancer. Methods　Clinical data of 346 consecutive patients (M/F=1.39, age range 32-84 years, median age 58.5 years) undergone anterior resection for rectal cancer in this institute from January 2006 to December 2008 were analyzed retrospectively. Results　The anastomotic leakage rate was 0 (0/185) and 5.59%(9/161) in patients with or without receiving large-calibre transanal tube drainage respectively. The anastomotic leakage rate was significantly decreased by large-calibre transanal tube drainage after anterior resection for rectal cancer (χ2=8.526, P=0.004). Eight cases of anastomotic leakage were treated conservatively and the other one required further surgical interventions. No perioperative death occurred in this series. Conclusion　In this study, the large-calibre transanal tube drainage and decompression is effective in protecting rectal anastomosis and decreasing the rate of anastomotic leakage.
