    Background: Since most anastomoses after left-sided colorectal resections are performed with a circular stapler, any technological change in stapling devices may influence the incidence of anastomotic adverse events. The aim of the present study was to analyze the effect of a three-row circular stapler on anastomotic leakage and related morbidity after left-sided colorectal resections. Materials and methods: A circular stapled anastomosis was performed in 4255 (50.9%) out of 8359 patients enrolled in two prospective multicenter studies in Italy, and, after exclusion criteria to reduce heterogeneity, 2799 (65.8%) cases were retrospectively analyzed through a 1:1 propensity score-matching model including 20 covariates relative to patient characteristics, to surgery and to perioperative management. Two well-balanced groups of 425 patients each were obtained: group (A) – true population of interest, anastomosis performed with a three-row circular stapler; group (B) – control population, anastomosis performed with a two-row circular stapler. The target of inferences was the average treatment effect in the treated (ATT). The primary endpoints were overall and major anastomotic leakage and overall anastomotic bleeding; the secondary endpoints were overall and major morbidity and mortality rates. The results of multiple logistic regression analyses for the outcomes, including the 20 covariates selected for matching, were presented as odds ratios (OR) and 95% confidence intervals (95% CI). Results: Group A versus group B showed a significantly lower risk of overall anastomotic leakage (2.1 vs. 6.1%; OR 0.33; 95% CI 0.15–0.73; P = 0.006), major anastomotic leakage (2.1 vs. 5.2%; OR 0.39; 95% CI 0.17–0.87; P = 0.022), and major morbidity (3.5 vs. 6.6% events; OR 0.47; 95% CI 0.24–0.91; P = 0.026). Conclusion: The use of three-row circular staplers independently reduced the risk of anastomotic leakage and related morbidity after left-sided colorectal resection. Twenty-five patients were required to avoid one leakage

    Transanal endoscopic microsurgery for the treatment of selected patients with distal rectal cancer: 15 Years experience

    No full text
    Background: Local therapy for early rectal cancer is a valid alternative to the classical radical operation, which has a higher morbidity and mortality rate. The use of high-dose preoperative radiation appears to enhance the options for sphincter-saving surgery even for T2-T3 rectal cancer patients with effective local control. The authors report their experience with transanal endoscopic microsurgery (TEM) used to manage selected cases of distal rectal cancer without evidence of nodal or distant metastasis (N0-M0). Methods: The study enrolled 196 patients with rectal cancer (51 T1, 84 T2, and 61 T3). All the patients staged preoperatively as T2 and T3 underwent preoperative high-dose radiotherapy, and since 1997, patients younger than 70 years in good general condition also have undergone preoperative chemotherapy. Results: Minor complications were observed in 17 patients (8.6%) and major complications in only 3 patients (1.5%). The definitive histology was 33 pT0 (17%), 73 pT1 (37%), 66 pT2 (34%), and 24 pT3 (12%). Eight patients (5 pT2 and 3 pT3) experienced local recurrence (4.1%). The rectal cancer-specific survival rate at the end of the follow-up period was 100% for pT1, 90% for pT2, and 77% for pT3 patients. Conclusions: Patients with T1 cancer and favorable histologic features may undergo local excision alone, whereas those with T2 and T3 rectal cancer require preoperative radiochemotherapy. The results in the authors' experience after TEM appear not to be substantially different in terms of local recurrence and survival rate from those described for conventional surgery. © 2008 Springer Science+Business Media, LLC
