title: Single-incision versus conventional laparoscopic distal pancreatectomy: a single-institution case-control study.
abstract: OBJECTIVE
  Laparoscopic distal pancreatectomy is becoming increasingly established at specialized surgical institutions worldwide. The purpose of this study was to compare single-incision laparoscopic distal pancreatectomy (panLESS) with conventional laparoscopic distal pancreatectomy (panLAP) to assess feasibility and 30-day morbidity.
  
  
  METHODS
  Eight consecutive patients who underwent panLESS were matched with patients who underwent panLAP in the same time period. Matching criteria were age, body mass index, and American Society of Anesthesiologists score. Feasibility was based on tumor size, operative time, intraoperative bleeding, resection status, and hospital stay. Thirty-day morbidity was defined by the revised Accordion Classification system and the International Study Group on Pancreatic Fistula definition.
  
  
  RESULTS
  Over a 19-month period, 8 and 16 patients were identified for panLESS and panLAP, respectively. There were no significant differences in tumor size, operative time, intraoperative bleeding, resection status, and hospital stay between the two groups. Surgical complications developed in four panLESS patients and five panLAP patients, and out of which, two patients from each group developed a postoperative pancreatic fistula (grade B).
  
  
  CONCLUSIONS
  This study indicates that panLESS is comparable to panLAP in terms of feasibility. More experience is needed to define what role single-incision distal pancreatectomy should have in minimal invasive pancreatic surgery.
