RESUMEN
Complications related to CO2 pneumoperitoneum in laparoscopy surgery have led to the devel-opment of gasless laparoscopic surgery using abdominal wall lifting technique.The technique uses facilitate laparoseopic surgery without conventional pneumoperitoneum and markly reduced in the risks of anesthesiolo-gy,especially in old patients with cardiopulmonary insufficiency.The review summarizes the application of gasless laparoscopie surgery using abdominal wall lifting technique in the field of general surgery.
RESUMEN
Objective To evaluate the safety,efficacy and advantages of laparoscopic colorectal surgery for elderly patients with colorectal cancer.Methods Operation safety,complications,and postoperative recovery of 35 patients aged 70 years and over who underwent laparoscopic colorectal surgery(LAPA group) were analyzed retrospectively and compared with those of 78 elderly patients performed with conventional open surgery(OPEN group) and 35 patients younger than 65 years performed with laparoscopic colorectal surgery(LAPB group) between December 2002 and December 2003.Results No surgery-related death occurred in LAPA group and LAPB group,but 2 deaths were found in OPEN group because of severe pulmonary infection and anastomotic leakage respectively.There were 33 (42.3%) cases of complications in the OPEN group which were significantly more than those in LAPA and LAPB group (P0.05).Local recurrence rate,metachronous metastases rate and cumulative survival probability at 30 months were similar in the LAPA and OPEN groups.Conclusions Laparoscopic colorectal surgery is safe and beneficial to the patients aged 70 years and over and it could be adopted widely.
