Abstract
A case of a 32-year-old patient who presented with vaginal bleeding 2 years after undergoing laparoscopic radical trachelectomy and vaginal cerclage was noted to have Mersilene tape erosion. Subsequent management includes the removal of displaced Mersilene tape and a repeat cerclage through a new technique of laparoscopic abdominal cerclage to avoid repeat tape erosion. The novel technique of laparoscopic abdominal cerclage to lower the incidence of preterm delivery among pregnant patients who underwent laparoscopic radical trachelectomy for early-stage cervical cancer is described.

INTRODUCTION
Fertility-sparing surgery for early-stage cervical cancer has been practiced for more than two decades and the first radical laparoscopic radical trachelectomy for early-stage cervical cancer was performed by Lee et al.[1,2,3] Although cervical cancer is the fourth leading cause of cancer among women, the majority of cases are noted during the reproductive years. Empowered women tend to prioritize establishing their careers over early marriage and pregnancy. This situation led to the development of fertility-sparing surgery among women who were diagnosed with cancer. In the advent of regular papanicolaou smear and Human Papilloma Virus (HPV) test, patients who choose to undergo vaginal, abdominal, or laparoscopic radical trachelectomy can have a close follow-up of cervical cancer recurrence; hence, giving them the chance for future fertility. In some patients who underwent vaginal cerclage or laparoscopic abdominal cerclage after radical trachelectomy, tape erosion is one of the reported complications. We discuss a modified technique of laparoscopic transabdominal cerclage with the aim of preventing repeat Mersilene™ tape erosion in a patient who underwent laparoscopic radical trachelectomy with vaginal cerclage.
CASE REPORT
A 32-year-old nulligravid woman underwent an annual health examination 2 years before admission wherein a pap smear revealed squamous cell carcinoma. The patient underwent conization in a tertiary hospital and was diagnosed with squamous cell carcinoma of the cervix stage IB1. The patient had no regular pap smear or HPV vaccination. Since the patient is desirous of pregnancy, the consult was done with another gynecologist and underwent laparoscopic radical trachelectomy, sentinel lymph node biopsy, and vaginal cerclage. Histopathologic examination revealed: cervix, radical laparoscopic trachelectomy specimen–ulcer; vaginal, laparoscopic trachelectomy–negative for malignancy; bilateral pelvic lymph node (Indocyanine Green (ICG) positive for detection)–negative for malignancy. The patient underwent regular follow-ups until 6 months before admission, and irregular vaginal bleeding was noted prompting a consult with a gynecologist. Upon speculum examination, there was noted protrusion of 2 cm tape into the vaginal canal, as shown in Figure 1a. The patient underwent the removal of the protruded Mersilene™ tape vaginally [Figure 1b] and repair [Figure 1c].
Four months after the removal of the eroded Mersilene tape, the patient was readmitted for repeat laparoscopic transabdominal cerclage [Figure 2a and b].
The technique in the repeat laparoscopic abdominal cerclage is described as follows: (a) A primary port is placed in the Lee-Huang Point and three accessory ports were made,[4] (b) Pelvic inspection and lysis of previous adhesions, (c) Inspection and identification of bilateral ureter, (d) Creation of bilateral broad ligament window, (e) Mersilene tape is passed thru the created right broad ligament window embedding the Mersilene tape in the anterior myometrium of the lower uterine segment and passed thru the left broad ligament window to avoid displacement and repeat erosion because of the absence of the cervico-uterine junction, (f) Both ends of the Mersilene tape are tied at the lower posterior uterine wall and secured with laparoscopic clips to avoid slippage.
In the current technique, the Mersilene tape is passed through the tunneled or dissected vesico-uterine peritoneum while in this modified technique, the Mersilene tape is embedded in the myometrium to avoid the complications of urinary bladder erosion and displacement to other surrounding pelvic structures.
The patient was discharged improved with no complications after 6 months of follow-up.
DISCUSSION
Vaginal mesh erosion is one of the reported complications of vaginal/laparoscopic placement of mesh for pelvic organ prolapse.[5] Only a few cases were reported regarding complications after vaginal or laparoscopic abdominal cerclage using Mersilene tape following radical trachelectomy.[6,7,8,9,10] Placement of foreign body such as Mersilene tape can be a risk factor for poor wound healing; hence, prone to infection which is seen in the index patient as vaginal mersilene tape erosion. Dissection of the pelvic floor spaces may contribute to the disruption of the integrity of the pelvic floor.
Placement of a laparoscopic transabdominal cerclage in patients after trachelectomy is challenging because of the absence of the cervico-uterine junction.[11] In this case, since the patient had previous cerclage placed vaginally during laparoscopic radical trachelectomy that resulted in a cerclage erosion, the surgeon opted to embed the Mersilene tape in the anterior myometrium of the neo-cervix or lower uterine segment, avoiding slippage, and possible erosion. Obstetric outcomes of patients who underwent radical trachelectomy include preterm prelabor rupture of membrane, preterm delivery, and spontaneous abortion.[6]
Mersilene tape erosion among patients who underwent cerclage after laparoscopic radical trachelectomy is rare but can cause additional psychological stress to patients. Determining the appropriate and standardized technique of laparoscopic abdominal cerclage among postradical trachelectomy patients is challenging but necessary to avoid repeat cerclage erosion and to attain improved obstetrical outcomes.[12,13]
Most published literature regarding placement of vaginal or abdominal cerclage focuses on the pregnancy outcome as well as complications but rare to find published literature on the prevention of tape complications such as erosion. Long-term follow-up as to the outcome of this modified technique is highly suggested.
