title: Single-port laparoscopic colectomy is safe and feasible in patients with previous abdominal surgery.
abstract: BACKGROUND
  The aim of this study was to assess the impact of previous abdominal surgery (PAS) on single-port laparoscopic colectomy (SPLC).
  
  
  METHODS
  We studied 429 consecutive patients who underwent SPLC in our department from May 2009 to December 2013. Patients were divided into 2 groups: those with PAS (PAS group) and those with NPAS (NPAS group). Operative parameters and outcomes were analyzed between the 2 groups retrospectively.
  
  
  RESULTS
  SPLC was performed in 152 PAS patients and 277 NPAS patients. Eight patients in the PAS group and 6 patients in the NPAS group were converted to multiport laparoscopic colectomy (5.3% vs. 2.2%, respectively; P = .077). Three patients in the PAS group and 2 patients in the NPAS group had inadvertent enterotomy (2.0% vs. .7%, respectively; P = .352). No patients were converted to open surgery. There were no significant differences between the 2 groups in terms of blood loss, operative time, and postoperative outcomes.
  
  
  CONCLUSIONS
  Our experience has demonstrated the safety and feasibility of SPLC in patients with PAS.
