The posterior colpotomy: An alternative approach to tissue extraction

Manual morcellation will be necessary for the second, larger myoma. We perform that morcellation sharply using a scalpel within the specimen retrieval bag, taking care not to puncture the bag (FIGURE 8). When the myoma pieces are small enough, we remove them, along with the bag, through the posterior colpotomy. We then close the colpotomy laparoscopically using two interrupted 0 Vicryl sutures, and we copiously irrigate the pelvis (FIGURE 9).

Figure 6: Remove the Access Port Prior to tissue extraction, remove the Access Port from the vagina. Figure 7: Exteriorize the bag Exteriorize the specimen-retrieval bag vaginally for tissue extraction.

Figure 8: Contain the morcellation Manually morcellate the specimen within the bag and remove it transvaginally. Figure 9: Close the colpotomy Close the colpotomy once both myomas and the specimen bag have been removed.

Benefits of this approach
The greatest benefit of this technique is the safe removal of specimens when performing fertility-sparing surgery. The 5-mm incisions are cosmetically inconspicuous. Moreover, the risk of port-site hernia is lower with 5-mm incisions, as opposed to extended incisions to remove specimens transabdominally.

The posterior colpotomy is associated with reduced pain and does not increase the rate of dyspareunia or infection; it also helps prevent pelvic adhesions.^8–11

In 1993, we reported the results of ­second-look laparoscopy in 22 women who had undergone laparoscopic posterior colpotomy for tissue extraction. None had obliterative adhesions in the posterior cul-de-sac.¹¹ This advantage is especially important in fertility-sparing surgery.

We have used this approach for specimen removal after several different procedures, including laparoscopic cystectomy and appendectomy.^12,13 For laparoscopic cystectomy, once the cyst is drained, we enucleate it and place the cyst capsule into a specimen bag that has been inserted transvaginally through a posterior colpotomy.¹² Laparoscopic appendectomy can be ­performed using a 12-mm stapler introduced via the colpotomy. We simply remove the specimen in its entirety through the posterior colpotomy.¹³

The bottom line: Gynecologic surgeons need to continue performing minimally invasive surgery for the benefit of patients. Moving forward and innovating to develop alternatives to intracorporeal power morcellation, when possible, should be our aim rather than falling back on surgeries through large abdominal incisions.

CASE: Resolved
At her 1-week postoperative visit, the patient’s 5-mm incisions are healing well and she has minimal pain.
