Single-port LC Might be Preferable for Managing Ovarian Dermoid Cyst.
Study Details
Study Description
Brief Summary
Minimally invasive surgery has become the standard treatment for many gynecologic disease processes. In the last decade, numerous studies have demonstrated that laparoscopic approaches to various gynecologic oncology conditions-particularly for early-stage endometrial and cervical cancers as well as select pelvic masses-is feasible and results in shorter hospital stays, improved quality of life and comparable surgical and oncologic outcomes to abdominal staging.For instance, the typical gynecologic robotic surgical procedure will require Two to three 5-mm ports and one 12-mm laparoscopic ports. Recently, an even less invasive alternative to conventional laparoscopy surgery has been developed: laparoendoscopic single-site surgery (LESS), also known as single-port surgery. Single port laparoscopy is an attempt to further enhance the cosmetic benefits of minimally invasive surgery while minimizing the potential morbidity associated with multiple incisions. Preliminary advances in LESS as applied to urologic and gastrointestinal surgery demonstrate that the techniques are feasible provided that both optimal surgical technical expertise with advanced skills and optimal instrumentation are available. Recently, several publication showed the single port laparoscopic surgery is feasibility in gynecologic surgery including oophorectomy, cystecomty, and myomecomty. To our knowledge, the sample size of recent publication about single port surgery including cystectomy and myomecomty is small. Furthermore, these studies lack the comparison of single port and convectional laparoscopic surgery. Base on our recent study demonstrated that either the single-port or the conventional approach can be used for LAVH, but the single-port LAVH technique yielded less postoperative pain (Chen et al., Obestet Gynecol, 2011). The purpose of this study was to assess the feasibility of single port laparoscopic surgery in the treatment of benign gynecologic disease.

Detailed Description
This study was designed as a retrospective case-control study, and port placement was one of the differences in operative procedures between the two groups. Patients with ovarian dermoid cysts were evaluated at Taipei Veterans General Hospital from June 13, 2011 through June 12, 2013. Approval for the study was obtained from the hospital's ethics committee, and informed consent was obtained from all patients (VGHIRB 2011-06-004IA).

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Single-port laparoscopy The three-channel single-port: a 1.5-cm horizontal intraumbilical skin incision, a 1.5-cm to 2-cm rectus fasciotomy to open the peritoneal cavity, and the insertion of an Alexis small wound retractor (Applied Medical, Rancho Santa Margarita, CA). The wrist portion of a size 6.5 surgical glove was fixed to the outer ring of the wound retractor. A 12-mm trocar was inserted through a small hole made in one of the fingertips of the glove and advanced into the abdominal cavity. Two additional holes for the accessory channels were made in another fingertip of the glove, and two conventional 5-mm trocars were inserted through the holes. |
Procedure: Ovarian cystectomy

| Active Comparator: Conventional laparoscopy The 12-mm main troca was inserted via subumbilical incision after fully insufflation by verness needle and other 3 working 5-mm trocas were inserted under vision at right middle abdominal, left middle abdominal and suprapubic incisions. |
Procedure: Ovarian cystectomy

Outcome Measures
Primary Outcome Measures
- The outcome measures and ovarian reserve between single-port and conventional laparoscopic cystectomy in managing ovarian dermoid cysts. [The first 48 hours and 4 weeks after the surgery]
The outcome measures included operative time, blood loss, postoperative pain, and analgesic use in the first 48 hours after surgery.
Secondary Outcome Measures
- Ovarian reserve were compared with single-port and conventional laparoscopic cystectomy in managing ovarian dermoid cysts. [Before and 4 weeks after surgery.]
Ovarian reserve markers include serum estrogen (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and anti-Mullerian hormone (AMH) before and 4 weeks after surgery.
Other Outcome Measures
- Ovarian spillage and endobag rupture rates were compared between single-port and conventional laparoscopic cystectomy in managing ovarian dermoid cysts. [During operation.]
The ovarian spillage and endobag rupture rates were compared between single-port and conventional laparoscopic cystectomy in managing ovarian dermoid cysts during operation.
Eligibility Criteria
