The University of Chicago technique of complete intracorporeal pediatric robotic-assisted laparoscopic augmentation ileocystoplasty and Mitrofanoff appendicovesicostomy

Abstract

We present the University of Chicago technique for complete intracorporeal robotic-assisted laparoscopic augmentation ileocystoplasty and Mitrofanoff appendicovesicostomy. The operative steps of the open procedure were replicated laparoscopically using robotic assistance. Initially, five transperitoneal laparoscopic ports are placed prior to docking the da Vinci S robotic system. A 20 cm ileal segment is isolated, and the gastrointestinal anastomosis is performed in an end-to-end fashion using intracorporeal suturing. The appendix is anastomosed to the right posterior wall of the bladder over an 8F feeding tube in an extravesical fashion. Then, the bladder is incised in a coronal plane, and the simple detubularized ileal on-lay patch is anastomosed to the posterior and anterior walls of the bladder. A suprapubic catheter and pelvic drain are placed. Finally, the Mitrofanoff stoma is then fashioned. Cystography is done at 4 weeks postoperatively. This report suggests that robotic-assisted ileocystoplasty and appendicovesicostomy is feasible. A reasonable outcome with early recovery, resumption of normal activities, and excellent cosmesis can be achieved in select patients. A large case series, however, is necessary to determine whether a robotic-assisted approach provides any significant advantages over conventional open procedures.
