About this study

The study is a randomized clinical trial (RCT) including patients undergoing robotic assisted cystectomy with intracorporeal ileal conduit at four large university hospitals in Denmark.

If included, the patients will be randomized 1:1 to two study arms: 1) Standard arm with current procedure where intracorporeal bowel anastomosis is performed with the 60 mm EndoGIA stapler, or 2) Experimental arm where the bowel anastomosis will be performed totally robotic with the Endowrist Intuitive robotic stapler with 2 subsequent elongated 45 mm magazines for the side-to-side anastomosis.

Primary outcome will be postoperative bowel function where a better bowel recovery is anticipated in the experimental Endowrist arm whereas serious complications are expected to be non-inferior to the current standard.

Read the detailed description

Cystectomy with urinary diversion is the standard treatment of muscle invasive and high risk non-muscle invasive bladder cancer. During cystectomy, a urinary diversion is constructed from a bowel segment. Restoration of the intestinal continuity is therefore an obligate part of the procedure.

In Denmark, approximately 400 radical cystectomies are performed yearly with the majority of procedures performed as a laparoscopic robot assisted procedure. This includes urinary diversion by means of intracorporeal procedure.

During current standard intracorporeal urinary diversion, an Endo-GIA stapler is handled by the assisting surgeon and not by the main surgeon as the Endo-GIA stapler is not integrated into the robot.

The traditional Endo-GIA anastomosis is made as a side-by-side anastomosis with two 60 mm magazines: one for the side-to-side anastomosis and one for closing the end.

Any reduction in the lumen of the anastomosis will clinically affect post-operative bowel function. It is known that at all cystectomy patients have intestinal paralysis / lack of normal bowel function in the first days postoperatively. It is thus plausible that a wider anastomosis will be able to reduce the duration of this in favor of the patient's post-operative nutrition, postoperative length of stay and convalescence.

A stapler integrated in the robot (Endowrist stapler from Intuitive) is available. This has several advantages: it is operated by the robotic surgeon and not by the assistant, it is more flexible, and faster mobility. These advantages provide the possibility of precisely removing a minimal intestinal segment by the final transverse stapling. The biggest disadvantage of the robot-operated Endowrist staple is that it is not available in a 60 mm version but only in 45 mm, thus giving only an anastomosis of approximately the same lumen as using a 60 mm Endo-GIA staple but not better.

An opportunity to make a more spacious anastomosis would be to "prolong" the longitudinal stapling as to the side-to-side anastomosis between the intestinal segments. This requires precise and coordinated handling of bowel graspers and staplers to make a complete elimination of the risk of anastomosis leakage, which in this respect is an advantage of robot-operated staples with the Endowrist stapler rather than an assistant handled stapler with Endo-GIA.

Both Endo-GIA and Endowrist stapler are approved for clinical use according to the procedures described.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Postoperative bowel function

    Primary outcome will be postoperative bowel function where a better bowel recovery is anticipated in the experimental Endowrist arm whereas serious complications are expected to be non-inferior to the current standard.

    Measured: 90 days
