title: Endoscopic stenting for recurrence-related colorectal anastomotic site obstruction: preliminary experience.
abstract: OBJECTIVE
  To evaluate the efficacy of stents in treating patients with anastomotic site obstructions due to cancer recurrence following colorectal surgery.
  
  
  METHODS
  The medical records of patients who underwent endoscopic self-expanding metal stents (SEMS) insertion for colorectal obstructions between February 2004 and January 2014 were retrospectively reviewed. During the study period, a total of 218 patients underwent endoscopic stenting for colorectal obstructions. We identified and examined the patients who underwent endoscopic stenting for obstructions caused by cancer recurrence at the anastomotic site following colorectal surgeries for primary colorectal cancer.
  
  
  RESULTS
  Five consecutive patients [mean age, 56.4 years (range: 39-82 years); 4 women, 1 man] underwent endoscopic stenting for obstructions caused by cancer recurrence at the anastomotic site following colorectal surgeries for primary colorectal cancer. Technical and clinical success was achieved in all 5 patients, without any early complications. During follow-up, 3 patients did not need further intervention, prior to their death, after the first stent insertion; thus, the overall success rate was 3/5 (60%). Perforations occurred in 2 patients who required a second SEMS insertion due to re-obstruction; none of the patients experienced stent migration.
  
  
  CONCLUSIONS
  SEMS placement is a promising treatment option for patients who develop obstructions of their colonic anastomosis sites due to cancer recurrence.
