Tubectomy of Pregnant and Non-pregnant Female Balinese Macaques (Macaca Fascicularis) With Post-operative Monitoring

peer reviewedWorldwide, primates, and humans increasingly share habitats and often enter in conflict when primates thrive in human-dominated environments, calling for special management measures. Reproductive control is increasingly used to manage population growth but very few monitoring data are available. Therefore, the efficiency and implications of such programs require a careful examination. In the context of a contraception program in wild female long-tailed macaques in Ubud, Bali, conducted over four successive campaigns between 2017 and 2019, including 140 females (i.e., 41.9% of the reproductive females of the population in 2019), modifications of an endoscopic tubectomy procedure, a permanent sterilization method, clinical evaluation of this method, and the post-operative monitoring results of the neutered females after release are described. This surgical approach was applicable for pregnant females: 28.6% of the treated females were pregnant at the time of the surgery. The procedure used a single lateral port to reach and cauterize both oviducts in non-pregnant as well as in early to mid-term pregnant females. Pregnant females nearer to term required a second lateral port to access both oviducts masked by the size of the gravid uterus. Moreover, bipolar thermocauterization was utilized successfully without resection to realize the tubectomy. The average duration of the laparoscopic surgery was 14 min for non-pregnant females and 22 min for pregnant females. Animals were released 3 h 22 min in average following their capture. This short holding time, recommended for free-ranging primates, was made possible by the minimal invasiveness of the sterilization approach. A laparoscopic post-operative evaluation conducted on two patients during the following campaign confirmed that the oviducts were definitely disrupted and no longer patent. Moreover, no new pregnancies in sterilized females were recorded during the 3-year observation period. The survival rate of the treated females 6 months after sterilization was high (96.3%) with no major post-operative complications clinically recorded. Among females that were pregnant during surgery, 81.1% were confirmed to experience term delivery. This study demonstrates the safety and efficiency of endoscopic tubectomy, even for pregnant females, as a mean of wild macaques' population control

Gynecologic laparoscopic surgery with a palm-controlled laparoscope holder.

During laparoscopic surgery, the operator relies on the skills of an assistant, particularly during laparoscope manipulation. If possible, the surgeon would prefer to hold the scope while at the same time operating with both hands similar to open surgery conditions. A palm electronic interface (Lapman) was developed to allow remote control of a laparoscope manipulator and to make laparoscope displacement and instrument manipulation synchronous for the surgeon. It was tested in gynecologic surgery, where it restored vision and instrument manipulation and allowed laparoscopic surgery to be performed with fewer personnel

Using a laparoscope manipulator (LAPMAN) in laparoscopic gynecological surgery

The LAPMAN(R) (Medsys, Gembloux, BELGIUM) is a dynamic laparoscope holder guided by a joystick clipped onto the laparoscopic instruments under the index finger of the operator. It confers optimal control of the visual field while operating, ensures stable and smooth displacement of the laparoscope, and allows the operator to work in conditions of restricted surgical assistance, due to either unavailability of staff or economic constraints. It has been tested successfully in pilot studies in laparoscopic gynecologic surgery

Place de l’hystéroscopie ambulatoire avant FIV

L’hystéroscopie ambulatoire est une technique très utile dans la prise en charge de la patiente FIV parce qu’elle permet a la fois un diagnostic intra-utérin précis pour des anomalies affectant l’implantation embryonnaire et le traitement immédiat de ces anomalies. Beaucoup plus confortable qu’avant et très sure, elle va aujourd’hui jusqu’à permettre d’occlure les hydrosalpinx avant le transfert embryonnaire et l’on pense qu’elle pourrait favoriser l’implantation chez les patientes avec échecs répétés d’implantation.[The role of ambulatory surgery prior to IVF] Outpatient hysteroscopy is very useful when managing in vitro fertilization (IVF) patients, as it enables a precise diagnosis of intrauterine pathologies known to affect embryo implantation, along with their rapid and effective treatment. The conditions surrounding this investigative method are more comfortable than before and very safe. At the present time, hysteroscopy allows us to manage hydrosalpinges. Although this is still questionable, the technique may also promote embryo implantation in IVF patients with recurrent implantation failure

ELITT: Endometrial laser intrauterine thermo-therapy

The endometrial laser intrauterine thermo-therapy (ELITT) uses diode laser-light energy combined with interstitial thermo-therapy fiber technology. Its ability to induce amenorrhoea demonstrating its inherent efficacy is worthy of note. The current article reviews the principles of this technology and the data obtained from the first clinical studies using it

Laparoscopic myolysis.

This review will focus on the different techniques and the long-term effects of the technique called myolysis on myoma growth. Indications for myolysis are essentially pelvic pain, compression symptoms and global uterine volume in order to avoid hysterectomy. In the late 1980s, myolysis was performed laparoscopically with the help of the neodynium: yttrium aluminium garnet (Nd:YAG) laser. Later, bipolar needles were developed as an alternative to the Nd:YAG laser. Diathermy and cryomyolysis were also proposed but series are small in the literature. Very recently, myoma interstitial thermo-therapy (MITT) was performed using the diode laser and a specific optical light diffuser that is designed to transmit laser light in all directions. Laparoscopic myolysis was proved to be effective in provoking myoma shrinkage, with a dramatic decrease in size and a marked devascularization of the myoma and this technique can be proposed as an alternative to myomectomy in selected patients: only those aged >40 years or those not desiring to bear any more children

LASH: laparoscopic supracervical (subtotal) hysterectomy

peer reviewedFrom July 1990 to December 1993, 156 laparoscopic supracervical hysterectomies (LASH) were performed. No complications occurred. The technique and the advantages are described. Because of the easy feasibility of this technique, the quick recovery of the patients and the absence of complications this strictly laparoscopic approach must be widely proposed when an hysterectomy is indicated and no risk of remaining cervix cancer is assumed

Hysteroscopic myomectomy.

Transhysteroscopic myomectomy has proved to be safe and effective with experienced operators. The use of the continuous flow hysteroscope and preoperative monitoring of intrauterine pressure has contributed to the prevention of fluid intravasion accidents. Effectiveness has been demonstrated in a number of recently published long-term studies
