Blood loss is likely to be lower in patients undergoing laparoscopic colectomy compared with patients undergoing conventional open colectomy.
In this study, researchers from Cleveland, Ohio, matched patients undergoing laparoscopic colectomy for age, sex, comorbidity, and surgical procedure with patients undergoing open colectomy.
The team evaluated estimated blood loss, drop in hemoglobin levels, and transfusion requirements after surgery.

Between 2000 and 2001, 147 patients underwent the same operation using either an open or laparoscopic approach.
The researchers did not find any differences in American Society of Anesthesiologists class, body mass index, or preoperative and postoperative hemoglobin levels.
However, the open colectomy group required significantly more units of blood to maintain similar hemoglobin levels after surgery.
Furthermore, estimated blood loss and the number of patients who received transfusions on the day of surgery, during the first 48 hours after surgery, and during the entire hospital stay were significantly higher in the open colectomy group.
Dr Ravi Kiran's team concluded, "A laparoscopic approach for colorectal surgery led to significantly less blood loss than matched open colectomy cases".
