With the introduction of single port surgery, the presumed advantages were improved cosmesis, decrease of pain and shorter length of stay. The aim of this study was to compare early outcomes of single port colectomy versus conventional laparoscopic colectomy.
All consecutive patients undergoing single port colectomy between January and June 2010 were identified from a prospective database. They were matched for age, sex, BMI, ASA score and type of resection to patients who had conventional laparoscopic colectomy. All perioperative data, analgesic requirement, pain scores and inflammatory response were compared using Wilcoxon signed-rank and McNemar tests.
Fourteen patients (5 men, 9 women; median age (IQR) 56 (30-73) years, BMI (IQR) 22 (20-24) kg/m²) underwent single port colectomy and were matched with a patient who had conventional laparoscopic colectomy. Median operating times, estimated blood loss, pain scores, analgesic requirement, inflammatory response and length of hospital stay were similar. Median increase in incision length was significantly higher in the single port group (P=0.004), but maximal incision length for specimen extraction was comparable. There were no anastomotic leaks, wound infections and no 30-day readmissions.
Single port laparoscopic colectomy has similar outcomes to conventional laparoscopic colectomy with no apparent short-term benefits.
