Development of gasless laparoscopic devices and clinical application of gasless laparoscopic surgery / 中国微创外科杂志

ABSTRACT

Objective To research the clinical safety and feasibility of self-made devices in gasless laparoscopic surgery. Methods A total of 5 generations of gasless laparoscopic devices (8 models) were designed and manufactured by ourselves from April 1993 to September 2004. After animal experiments, 15 types of different gasless laparoscopic operations were carried out in 87 patients. Results Out of the 87 cases, conversions to open surgery were required in 7 cases (conversion rate, 8.0%). The other 80 cases of gasless laparoscopic operations were successfully performed, involving cholecystectomy, colorectal resection, partial cecectomy, subtotal gastrectomy, inguinal herniorrhaphy, abdominal wall contraction, radical resection for carcinoma of renal pelvis, haital herniorrhaphy with Toupet’s fundoplication and total hysterectomy. Conclusions Our self-made gasless laparoscopic devices may be applied safely and effectively in clinical cases. Gasless laparoscopic surgery has been reflecting the complementary advantages of modern laparoscopic surgery and traditional open surgery. It is of supplementary significance in patients contraindicated to pneumoperitoneum and of distinctive importance for laparoscopic gastrointestinal surgery requiring abdominal fistulization or prolonged incision, as well as hand-assisted hepatobiliary or pancreatic laparoscopic surgery.
