A Japanese prospective multicenter study of self-expandable metal stent placement for malignant colorectal obstruction: short-term safety and efficacy within 7 days of stent procedure in 513 cases

Open surgery versus laparoscopic surgery after stent insertion for obstructive colorectal cancer

“…However, there was no significant difference in mortality or long-term outcomes between the two groups [8,17]. We previously reported on the high success rate of colonic stents after confirming the safety and feasibility of stent insertion for obstructive colon cancer [9]. Therefore, based on our experience and current evidence, we conclude that stent insertion before surgery, as BTS, is effective and safe, with a high success rate and low complication rate.…”

“…The colorectal obstruction scoring system (CROSS) classification score was 0 in all patients. Table 1 shows the CROSS classifications: Score 0 signifies obstruction requiring continuous decompression [9].…”

Self-expandable metallic stenting as a bridge to surgery for malignant colorectal obstruction: pooled analysis of 426 patients from two prospective multicenter series

“…In the WallFlex study, 312 of 518 consecutive patients enrolled in the registry were registered for SEMS placement as BTS [12, 13]. When enrollment was completed for the WallFlex study, the Niti-S study commenced using the same registry platform.…”

“…The ColoRectal Obstruction Scoring System (CROSS) is described in detail elsewhere [12, 13]. Briefly, the patient’s oral intake level is assessed as follows: CROSS 0, requiring continuous decompression; CROSS 1, no oral intake; CROSS 2, liquid or enteral nutrient intake; CROSS 3, soft solids, low-residue, and full diet with symptoms of stricture; or CROSS 4, soft solids, low-residue, and full diet without symptoms of stricture (Table 1).…”

“…JCSSPRG conducted two multicenter prospective feasibility studies to investigate the safety and effectiveness of colonic stenting. The first study was conducted using only the WallFlex™ enteral colonic stent (Boston Scientific Corporation, Marlborough, MA) [12, 13], and the second subsequent study was conducted using only the Niti-S™ type D enteral colonic stent (TaeWoong, Inc., Seoul, South Korea) in the same setting.…”
