title: [Application of hand-assisted laparoscopic surgery (HALS) in colectomy].
abstract: OBJECTIVE
  To evaluate the safety and efficacy of hand-assisted laparoscopic surgery (HALS) in colorectal tumors.
  
  
  METHODS
  Clinical data of 70 patients with colorectal tumors were retrospectively analyzed. All the patients had received HALS colectomy in the Beijing Cancer Hospital. Lapdisc was used for the hand port at the umbilicus. Two additional trocars were used.
  
  
  RESULTS
  There were 38 males and 32 females. The median age was 61(29-89) years. Diagnoses included sigmoid cancer(n=48), sigmoid adenoma(n=4), descending colon cancer (n=3), ascending colon cancer (n=1), rectal cancer (n=13), total colectomy(n=1). The operative time was (126.0±22.5) minutes. The intraoperative blood loss was (75.0±18.8) ml. The mean number of lymph node dissection was(16.8±4.2). The median postoperative hospital stay was 9.4 days. There were no perioperative deaths. One patient developed anastomotic stricture and two anastomotic leak, all of which were successfully managed with conservative treatment.
  
  
  CONCLUSIONS
  HALS is a safe and effective technique for colectomy.
