Problems solved by technology

Laparoscopy is therefore a surgical procedure and carries the risk of infection of the skin incisions and possible development of post-operative hernias, and / or scars which may create cosmetic defects.

example

[0052] We evaluated the feasibility, efficacy and safety of an endoscopic trans-gastric approach to the peritoneal cavity in a porcine model with long-term survival. Methods: 45-50 kg pigs had initial endoscopic needle-knife incisions of the gastric wall followed by balloon dilation / electrocautery of incision under general anesthesia using sterile techniques. Antibiotic irrigation of stomach was performed prior to initial incision for pigs #3, 4, 5. The endoscope underwent high level disinfection followed by gas sterilization and was advanced via sterile overtube into the peritoneal cavity for peritoneoscopy and liver biopsy. The gastric incision was subsequently closed with clip fixing devices. The pigs were sacrificed at 14 days. Peritoneal cultures, endoscopic and pathologic examinations were performed.

[0053] Results: 5 pigs had gastric incisions that were easily performed with rapid access to the peritoneal cavity using a sterile endoscope. Insufflation of the peritoneal cavity...

Abstract

A novel approach to diagnostic and therapeutic interventions in the peritoneal cavity is described. More specifically, a technique for accessing the peritoneal cavity via the wall of the digestive tract is provided so that examination of and / or a surgical procedure in the peritoneal cavity can be conducted via the wall of the digestive tract with the use of a flexible endoscope. As presently proposed, the technique is particularly adapted to transgastric peritoneoscopy. However, access in addition or in the alternative through the intestinal wall is contemplated and described as well. Transgastric and / or transintestinal peritoneoscopy will have an excellent cosmetic result as there are no incisions in the abdominal wall and no potential for visible post-surgical scars or hernias.

Description

[0001] This application claims the benefit of U.S. Provisional Application Ser. No. 60 / 191,764, which was filed Mar. 24, 2000, the disclosure of which is incorporated herein by this reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a procedure for accessing and examining and / or conducting surgical procedures in a body cavity, such as the peritoneal cavity, and instruments adapted therefor. [0004] 2. Description of the Related Art [0005] The traditional approach to the peritoneal cavity is by trans-abdominal wall incision. More recently, the less invasive laparoscopic surgical technique has been used to access and examine the peritoneal cavity. Laparoscopy is currently performed via small incisions made through the anterior abdominal wall. Via these incisions, a rigid laparoscope is introduced, as are various microsurgical instruments if a procedure is performed within the peritoneal cavity. Laparoscopy is therefore a surgi...
