Techniques for contained morcellation in gynecologic surgery.

Objective: To demonstrate 2 step-by-step techniques for contained morcellation of uterine tissue.

Design: Instructional video showing laparoscopic electromechanical morcellation within an endoscopic pouch, and alternatively, tissue extraction via ultra-minilaparotomy.

Setting: Academic medical center.

Patient(s): Women undergoing laparoscopic myomectomy or hysterectomy.

Intervention(s): For contained electromechanical morcellation, the specimen is placed within an endoscopic pouch, the edges of which are exteriorized through a 15-mm cannula. The cannula is repositioned inside the pouch for insufflation. A bladed fixation trocar enters the pouch through an assistant port and is secured by its retention disk and balloon tip. Gas inflow is changed to this assistant port, through which the laparoscope is inserted. A power morcellator is introduced via the 15-mm port site, and morcellation thus proceeds within the containment system. Residual fragments of tissue are collectively retrieved by withdrawing the endoscopic pouch. For tissue extraction via ultra-minilaparotomy, the specimen is placed within a pouch that is drawn up through a flexible, self-retaining retractor seated in a 2 to 3-cm incision. The specimen is cored out sharply with a scalpel.

Main Outcome Measure(s): None.

Result(s): Contained morcellation is technically feasible, efficient (mean additional operative time is approximately 30 minutes), and prevents intraperitoneal dispersion of tissue fragments. Our group has safely performed >100 such procedures and removed specimens weighing nearly 1,500 grams. Potential complications include viscous injury upon insertion of the bladed trocar, and pouch failure.

Conclusion(s): These techniques allow surgeons to adopt the new standard of contained morcellation and permit removal of extensive pathology with a minimally invasive approach.
