Abstract Background: Bridge to surgery (BTS) using a self-expandable metallic stent (SEMS) for the treatment of obstructive colorectal cancer improves the patient’s quality of life. This study aimed to examine prognostic factors of obstructive colorectal cancer. Methods: We analyzed stage II-III resectable colon cancer cases (Cur A) retrospectively registered between January 2005 and 2017. We encountered Cur A cases after BTS with SEMS placement (BTS group). We compared surgical results and prognoses between the two groups. Results: A total of 50 patients underwent endoscopic SEMS placement, which technical success of 96% and morbidity rate of 18%. Overall, 117 patients were evaluated: 67 of them underwent emergency surgery (ES) and 50 underwent BTS. Primary anastomosis rates were 77.6% in ES and 95.7% in BTS (p < 0.001); postoperative complication, 46.3% in ES and 10.5% in BTS (p < 0.001); pathological findings of lymphatic invasion, 66.7% in ES and 100% in BTS (p < 0.001); venous invasion were 66.8% in ES and 92% in BTS (p = 0.04); and recurrence of 25.4% in ES and 39.1% in BTS. The 3-year overall survival was significantly different between two groups (ES, 86.8%:BTS, 58.8%), BTS is worse than ES (log-rank test; p < 0.001). Venous invasion independently predicted worsened recurrence-free and overall survival. Conclusions: The vascular invasiveness was correlated with tumor progression after SEMS placement, and the survival rate was lower in BTS. SEMS potentially worsens prognostic outcomes in stage II–III obstructive colorectal cancer.

Abstract Purpose Advances in endoscopic technology have led to the reevaluation of self-expandable metallic stent (SEMS) placement as a bridge-to-surgery (BTS) in patients with obstructive colorectal cancer. In Japan, after inclusion of SEMS placement as a BTS in the medical insurance coverage in 2012, this procedure has been increasingly performed. However, a transanal decompression tube (TADT) placement has been used as a BTS. We aimed to retrospectively evaluate the optimal strategy for obstructive left-sided colorectal cancer (OLCRC) by comparing SEMS and TADT placement with emergency surgery. Methods We included 301 patients with stage II and III OLCRC from 27 institutions. The study patients were divided into Surgery group (emergency surgery, n = 103), SEMS group (BTS by SEMS, n = 113), and TADT group (BTS by TADT, n = 85). We compared the survival and perioperative outcomes of patients in the Surgery group as a standard treatment with those in the SEMS and TADT groups. Results The 3-year relapse-free survival rate in patients in the Surgery group was 74.8%, while that in patients in the SEMS group and TADT group were 69.0% (p = 0.39) and 55.3% (p = 0.006), respectively. The technical success rate was not statistically different, but the clinical success rate was significantly higher in the SEMS group than in the TADT group (p = 0.0040). With regard to postoperative complications after curative surgery, the SEMS group had significantly lower of complications (≥ grade 2) than the Surgery group (p = 0.022). Conclusion Patients who underwent SEMS placement for OLCRC had similar oncological outcomes to patients who underwent emergency surgery.

643 Background: Safety and validity of performing laparoscopic surgery after preoperative lavege using the self-expandable metallic stent (SEMS) for left-sided obstructive colorectal cancer were examined. We evaluated the short-term outcome of SEMS insertion compared with laparoscopic surgery without SEMS. Methods: Patients with left-sided colorectal cancer treated by either laparoscopic surgery with stent placement (n = 8) or laparoscopic surgery only (n = 42) in our hospital between April, 2012 and January, 2013 were registered. Short-term outcomes were compared with the two groups about patient characteristics (sex, age, American Society of Anesthesiologists Physical Status, body mass index, prior abdominal surgery), pathological data of patients (tumor location, size of tumor , tumor differentiation, number of harvested lymph nodes, pTNM classification, UICC pathological stage), and operative and post operative results (procedures, conversion, operative time, blood loss, morbidity, solid food intake, postoperative hospital stay, total hospital stay). Results: Except for tumor size in the patient characteristic parameters, there were no statistically significant difference between the two groups. Conversion rate to laparotomy was higher in the stent group (2 versus 1, p = 0.013). There was no difference in operation time, blood loss and postoperative complications between the two groups. Conclusions: Although the long-term oncological result requires further investigation, laparoscopic surgery after self-expandable metallic stent is a safe and feasible treatment as a “brige to surgery” for left-sided obstructive colorectal cancer.
