|Covidien Announces Study Results Demonstrating Benefits of Minimally Invasive Surgery over Traditional Open Procedures|
Separate video presentation shows feasibility of removing a part of a patient’s colon through a single incision
Both presentations were made at the annual meeting of the
Laparoscopic Surgery Study
Results of the data analysis revealed that laparoscopic surgery was associated with a decreased risk of blood transfusions and fewer surgical site infections, when compared to open surgery. The analysis also noted that laparoscopic procedures cost significantly less, on average, than open approaches.
“This robust analysis confirms that minimally invasive, laparoscopic
surgery is a strong alternative option to open surgery, with
demonstrably better clinical outcomes and cost benefits for the patient
across a variety of surgical procedures,” said primary investigator
The investigators evaluated data from patients undergoing common surgical procedures, including appendectomy, cholecystectomy, colectomy and gastric bypass.
Open procedures were associated with a 108 percent increased risk of
blood transfusions and a 174 percent increased risk of surgical site
infections, as compared to laparoscopic procedures.1 On
average, open surgery increased total costs by
“Years of clinical data from thousands of patients undergoing varying
forms of minimally invasive surgery consistently highlight improved
patient outcomes and cost efficiencies with this approach,” said
Dr. Geisler localized the tumor with lower endoscopy, then transected the rectum with Covidien’s Endo GIA™ 45 mm articulating medium/thick reload with Tri-Staple™ technology. He then exteriorized the bowel to remove the suspicious lesion and reattached the colon.
“Due to recent technical advances in instrumentation and an increased interest in exploring the feasibility of even less invasive surgical procedures, single port laparoscopic colorectal surgery is quickly gaining acceptance,” Dr. Geisler said. “Patients with chronic illnesses, such as ulcerative colitis or Crohn’s disease, often have to endure multiple invasive procedures, so surgeons are evaluating methods that remain clinically effective while reducing the recovery burden for patients. In this case, which was part of a larger 102-patient study, we demonstrate that, with proper training, it’s possible to resect the colon through a single incision. However, further studies are needed to assess the benefits of single port colorectal surgery over a conventional laparoscopic approach.”

LigaSure devices provide a unique combination of pressure and energy to permanently seal vessels up to and including 7 mm in size, lymphatics and tissue bundles. The average seal cycle is 2 to 4 seconds and seals withstand three times normal systolic blood pressure. The feedback-controlled response system automatically discontinues energy delivery when the seal cycle is complete, eliminating the guesswork. LigaSure technology has been used in millions of procedures worldwide and is supported by an ever-growing body of evidence-based research, now totaling over 300 published peer-reviewed studies.
