OBJECTIVES: A circular stapler introducer was developed to protect the head of the circular stapler and enable atraumatic introduction and advancement of the circular stapler without interfering with the application and safety of an anastomosis. METHODS: In a Phase I prospective study, we tested the feasibility and safety of the novel circular stapler introducer device in 60 consecutive patients undergoing left-sided colorectal resections. RESULTS: The median distance of the anastomoses from the anal verge was 12 cm (7-20, n = 60). Total morbidity was 15 percent. No mortality was observed. Handling of the circular stapler introducer was considered nonproblematic by all surgeons who participated in the study. No interference of the circular stapler introducer with the circular stapling devices used was encountered. The advancement of the stapler into the end of the colorectal stump was always possible with the aid of the circular stapler introducer. CONCLUSIONS: Use of the circular stapler introducer facilitates the double-stapling technique of colorectal anastomosis. The circular stapler introducer has great potential and should be tested in larger studies.

BACKGROUND: Modern laparoscopic bariatric surgery relies strongly on stapling devices and the perfection of the anastomotic technique is at the core of the patient's safety. METHODS: Circular stapler anastomosis is a common technique for performing gastro-jejunostomy in gastric bypass surgery. In obese patients, transabdominal circular stapler introduction can be challenging and associated with morbidity. To overcome these technical obstacles, we have developed a new device, circular stapler introducer (CSI) to assist both the abdominal wall passage of the circular staplers and its introduction into the jejunum. RESULTS: The CSI facilitates the insertion of the circular stapler not only into the abdomen but also into the jejunum enhancing safety and swiftness of laparoscopic Roux-en-Y gastric bypass. CONCLUSIONS: Our innovative CSI device facilitates this part of the operation significantly and makes the performance of bariatric surgery more convenient.
