Laparoscopic-assisted radical cystectomy with U-shaped orthotopic ileal neobladder constructed using nonabsorbable titanium staples.

INTRODUCTION: Recently, nonabsorbable staples have been safely used in a variety of urologic open and laparoscopic extirpative and reconstructive procedures. We report the surgical steps of our technique of U-shaped orthotopic ileal neobladder created with titanium staples. TECHNICAL CONSIDERATIONS: Using stay stitches, a 45 to 50-cm ileal segment is arranged in a U shape with two segments of approximately 20 cm and an afferent limb of 5 or 10 cm. An opening is made at the lowest point of the U-ileal segment on its antimesenteric border. The jaws of the 80 x 3.5-mm nonabsorbable mechanical stapler are accommodated within the bowel loop and fired twice, bringing together and detubularizing approximately 15 cm of each arm of the U. To complete the pouch detubularization, another small opening is made at the bottom of the chimney on its medial border. After this, a third nonabsorbable mechanical stapler had its jaws introduced through this opening and through the open end of the bowel segment on the right side and the stapler is fired, completing the U pouch. Subsequently, the open ends of the U segment and the opening made at the base of the afferent limb are closed with absorbable running sutures. CONCLUSIONS: Our technique is feasible and may represent an alternative to expand the spectrum of continent urinary reservoirs that could be expeditiously created with nonabsorbable staples. Continued surveillance is mandatory to determine the lithiasis-inducing potential of these titanium staples within the urinary tract.

Use of titanium knot placement device (TK-5) to secure dorsal vein complex during laparoscopic radical prostatectomy and cystoprostatectomy.

INTRODUCTION: We evaluated the feasibility and describe the surgical technique of using the Ti-Knot device TK-5 to secure the dorsal vein complex (DVC) during 20 consecutive cases of laparoscopic radical prostatectomy and cystoprostatectomy. TECHNICAL CONSIDERATIONS: Bloodless DVC ligation and transection was successfully achieved in 19 (95.03%) of 20 cases. In only 1 case, venous bleeding occurred after DVC transection. However, in this case, the two stitches used to ligate the DVC were tightly tied, and the bleeding probably occurred because the stitches were passed too superficially on the DVC. In another case, a third stitch had to be placed and tied with the aid of the Ti-Knot device because the second 2-0 Vicryl stitch placed at the DVC broke. In only 1 case did we experience some degree of trouble with the knotting process because one of the ends of the Vicryl suture slipped back into the abdominal cavity. The time to tie each suture with the Ti-Knot device, defined after the moment the needle was passed underneath the DVC to the moment the titanium knot was crimped and the Vicryl suture trimmed, was less than 1 minute (median 50 seconds, range 45 to 56) in all cases, except the case described above. No cases of the Ti-Knot device misfiring or malfunction occurred in this series. CONCLUSIONS: In our experience, the Ti-Knot titanium knot placement device proved to be safe and efficient during laparoscopic ligation and control of the DVC.

Laparoscopic assisted radical cystoprostatectomy with Y-shaped orthotopic ileal neobladder constructed with non-absorbable titanium staples through a 5 cm Pfannensteil incision.

INTRODUCTION: We performed a laparoscopic radical cystoprostatectomy followed by constructing a Y-shaped reservoir extra-corporeally with titanium staples through a 5-cm muscle-splitting Pfannenstiel incision. SURGICAL TECHNIQUE: Upon completion of the extirpative part of the operation, the surgical specimen was entrapped and removed intact through a 5-cm Pfannenstiel incision. Through the extraction incision, the distal ileum was identified and a 40 cm segment isolated. With the aid of the laparoscope, the ureters were brought outside the abdominal cavity and freshened and spatulated for approximately 1.5-cm. Bilateral double J ureteral stents were then inserted up to the renal pelvis and the ureters were directly anastomosed to the open ends of the limbs of the neobladder. Following this, the isolated intestinal segment was arranged in a Y shape with two central segments of 14 cm and two limbs of 6 cm. The two central segments were brought together and detubularized, with two sequential firings of 80 x 3.5 mm and 60 x 3.5 mm non-absorbable mechanical stapler (Multifire GIA--US Surgical) inserted through an opening made at the lowest point of the neobladder on its anti-mesenteric border. The neobladder was reinserted inside the abdominal cavity and anastomosed to the urethra with intracorporeal laparoscopic free-hand suturing. CONCLUSION: Although this procedure is feasible and the preliminary results encouraging, continued surveillance is necessary to determine the lithiasis-inducing potential of these titanium staples within the urinary tract.
