AimThis meta-analysis aims to compare hand-assisted laparoscopic surgery (HALS) with conventional laparoscopic surgery (LAS) for colorectal cancer (CRC) in terms of intraoperative, postoperative, and survival outcomes.Materials And MethodsA systematic literature search with no limits was performed in PubMed, Embase, and Medline. The last search was performed on March 31, 2017. The outcomes of interests included intraoperative outcomes (operative time, blood loss, length of incision, transfusion, conversion, and lymph nodes harvested), postoperative outcomes (length of hospital stay, time to first flatus, time to first bowel movement, postoperative complications, mortality, reoperation, ileus, anastomotic leakage, postoperative bleeding, wound infection, intra-abdominal abscess, urinary complication, cardiopulmonary complication, and readmission), and 5-year survival outcomes.ResultsNine articles published between 2007 and 2016 with a total of 1307 patients were enrolled in this meta-analysis. HALS was associated with longer length of incision. No differences were found for operative time, blood loss, transfusion, conversion, lymph nodes harvested, length of hospital stay, time to first flatus, time to first bowel movement, postoperative complications, mortality, reoperation, ileus, anastomotic leakage, postoperative bleeding, wound infection, intra-abdominal abscess, urinary complication, cardiopulmonary complication, readmission, or 5-year survival outcomes.ConclusionOur meta-analysis demonstrated that HALS is similar to LAS for CRC surgery in terms of intraoperative, postoperative, and survival outcomes except for the longer length of incision.
