Brief Summary

Modified Bakay technique offers a novel colpotomy and cuff closure technique for total laparoscopic hysterectomy (TLH), and consists of placing a single continuous running purse-string suture facilitating the cuff closure before colpotomy. The modified Bakay technique adds a standard apical compartment support and has the potential to facilitate the primary healing of the vaginal cuff. This study aimed to compare the surgical and clinical outcomes of the Modified Bakay technique to conventional standard technique in patients undergoing TLH.

Detailed Description

The basis for minimizing the rate of severe haemorrhage and ureteral injuries, the most serious events related to these steps, is meticulous dissection providing a clear operative field and the skill and experience of the surgeon. In total laparoscopic hysterectomy (TLH), the altered anatomy after the removal of the uterus may cause the retraction of vagina and shifting of neighbouring structures such as bladder and/or bowel to this pouch, thereby, leading to obstruction of the operative field for vaginal cuff closure.

Bakay published his novel colpotomy and cuff closure technique for TLH. It was the first to describe placing a single continuous running purse-string suture facilitating the cuff closure before colpotomy. The main advantage of the technique involved retrieving the safe suture margins required for vaginal cuff closure before the pelvic anatomy was altered by the removal of the uterus.

In addition to this advantage, we modified the technique to achieve a better cuff healing and standardized apical support and the modified Bakay technique (MT) proposes:

i) placing a single continuous running purse-string suture for vaginal cuff closure before the pelvic anatomy is altered by the colpotomy and removal of the uterus;

ii) suspension/plication of USLs (as a well-defined, efficient, concomitant apical support procedure to prevent future vaginal vault prolapse) routinely in each case before colpotomy while the margins of these ligaments and adjacent structures such as ureters are still prominent and pelvic anatomy is not altered; and

iii) using cold-knife colpotomy instead of electrosurgical colpotomy to support the primary healing of the vaginal cuff. In the present study, we aimed to compare the surgical and clinical outcomes of the MT to standard technique (ST) in patients undergoing TLH.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Modified technique (MT)

All the steps of the laparoscopic hysterectomy were performed according to conventional standard technique until the colpotomy step. Instead, the modified Bakay technique was used for later on.

Group Type: EXPERIMENTAL

Modified Bakay technique (MT)

Intervention Type: PROCEDURE

The conventional standard technique for laparoscopic hysterectomy was followed until the colpotomy. The remaining steps were as follows: A 0-Monocryl™ violet (poliglecaprone-25) or a 0-PDS-II (polydioxanone) suture with a 36-mm needle (Ethicon Inc., NJ, USA) was placed first on the right USL, proximal to the ischial spine and 1-3 cm away from its uterine insertion, then helically proceeded by 1 to 3 bite(s) (depending on the length of the ligament) for suspension/plication. The suture continued circumferentially in counter clockwise direction on the line between the cervicovaginal junction and the bladder in a full-thickness purse string fashion, at least 1 cm away to the bladder. This suture symmetrically ended in the left USL, with forming nearly an Ohm sign (Ω). Colpotomy was performed circumferentially using laparoscopic cold scissors and/or knife, maintaining a safe distance from the suture line. Following removal of the uterus, both ends of the prior suture line were knotted.

Standard technique (ST)

The conventional standard total laparoscopic hysterectomy technique was used in this control group.

Group Type: ACTIVE_COMPARATOR

Standard technique (ST)

Intervention Type: PROCEDURE

The conventional standard total laparoscopic hysterectomy technique was used in this control group.

All operations were performed under general anaesthesia with nasogastric intubation and a bladder catheter in place. Cefazolin 2 g was administered to all patients for prophylaxis 30 min prior to surgery. Operations were performed with a 10-mm laparoscope (Karl Storz, Germany) through the trocar placed usually in the umbilicus. Two lateral 5-mm trocars and one midline 10-mm trocar were used. The placement of trocars varied according to the uterine size. Haemostasis was usually performed using bipolar forceps (Karl Storz Robi, Germany), whereas dissection was performed using the LigaSure™ (Covidien, Medtronic, USA). Maryland jaw laparoscopic sealer/divider, bipolar forceps and scissors. Colpotomy was performed with electrocautery devices and sutured intracorporeally.
