title: Single-incision laparoscopy surgery: a systematic review.
abstract: BACKGROUND
  Laparoscopic surgery is a modern surgical technique in which operations are performed far from their location through small incisions elsewhere in the body.
  
  
  OBJECTIVE
  This systematic review is aimed to overview single-incision laparoscopy surgery.
  
  
  METHODS
  This systematic review was carried out by searching studies in PubMed, Medline, Web of Science, and IranMedex databases. The initial search strategy identified about 87 references. In this study, 54 studies were accepted for further screening and met all our inclusion criteria [in English, full text, therapeutic effects of single-incision laparoscopy surgery and dated mainly from the year 1990 to 2016]. The search terms were "single-incision," "surgery," and "laparoscopy."
  
  
  RESULTS
  Single-incision laparoscopy surgery is widely used for surgical operations in cholecystectomy, sleeve gastrectomy, cholecystoduodenostomy, hepatobiliary disease, colon cancer, obesity, appendectomy, liver surgery, rectosigmoid cancer, vaginal hysterectomy, vaginoplasty, colorectal lung metastases, pyloroplasty, endoscopic surgery, hernia repair, nephrectomy, rectal cancer, colectomy and uterus-preserving repair, bile duct exploration, ileo-ileal resection, lymphadenectomy, incarcerated inguinal hernia, anastomosis, congenital anomaly, colectomy for cancer.
  
  
  CONCLUSIONS
  Based on the findings, single-incision laparoscopy surgery is a scarless surgery with minimal access. Although it possesses lots of benefits, including less incisional pain and scars, cosmesis, and the ability to convert to standard multiport laparoscopic surgery, it has some disadvantages, for example, less freedom of movement, fewer number of ports that can be used, and the proximity of the instruments to each other during the operation.
