ZARATE C, ALEJANDRO et al. Results and complications in patients with sigmoid cancer: laparoscopic versus laparotomy. Rev Chil Cir [online]. 2008, vol.60, n.1, pp.29-34. ISSN 0718-4026.

Background: The laparoscopic surgery for colorectal cancer is an alternative to the laparotomy. The aim of this study is to compare results and early complications after a laparoscopic sigmoidectomy (LS) versus open surgery (OS) in patients with sigmoid cancer. Material and Method: Prospective and consecutive inclusion, by a study protocol of patients operated on for LS between 2000 and 2006. Comparative case-control design, the LS group was match with the OS group by age, sex, and ASA classification. Statistical analysis: Results were analyzed with intention to treat. The variables were analyzed with T Student, Chi-square, Mann-Withney and Fischer exact test, considering statistically significant a P value < 0.05. Results: Thirty-two patients by group were compared. The groups (LS vs OS) were statistically similar in age (65.6 v/s 67.3 years), gender (31.25% females each group), and ASA (p > 0.5). The mean operative time was higher in LS group (220 v/s 172 minutes, p <0.01). Conversion rate was 9.3%. The mean time to passing flatus and the time to reinitiate oral feeding were both shorter for LS group (2 v/s 4 days, p<0.01; and 3 v/s 5 days p <0.01). The mean total postoperative stay (5 v/s 8 days, p<0.01) was shorter for LS group. The postoperative medical complications were minor in LS group (9.3 v/s 27.5%, p <0.01), but the surgical complications were similar (6.25% each group). Lymph nodes resected and length of surgical specimens were similar for both groups (SL v/s OS: 22.7 v/s 22.1 lymphatic nodes p = 0.9 and 21.8 v/s 19.3 cm, p= 0.2). Conclusion: The development of laparoscopic colorectal surgery within a protocol, allows feasible the realization of laparoscopic sigmoidectomy for patients with sigmoid cancer with comparable surgical outcomes
