Diode laser use in hysteroscopic surgery: current status and future perspectives

Recent advances in surgical technology and innovative techniques have revolutionized surgical gynecology, including transcervical hysteroscopic procedures. Surgical lasers (Nd-Yag, Argon, diode, and CO2 lasers) have been promoted to remove a variety of gynecological pathologies. For hysteroscopic surgery, the diode laser represents the most versatile and feasible innovation, with simultaneous cut and coagulate action, providing improved hemostasis compared with CO2 laser. The newest diode laser devices exhibit increased power and a dual wavelength, to work precisely with reduced thermal dispersion and minimal damage to surrounding tissues. Their efficacy and safety have been validated both in the hospitals as well as in the office setting. Updated evidence reports that several hysteroscopic procedures, including endometrial polypectomies, myomectomies and metroplasties can be successfully performed with a diode laser. Therefore, this review aimed to give a deeper understanding of the role of laser energy in gynecology and subsequently in hysteroscopy in order to safely incorporate this technology into clinical practice.

Restoring Fertility of Patients with Severe Asherman's Syndrome in the Office Setting: A Step-by-Step Recipe for Success

OBJECTIVE

To describe an effective in-office hysteroscopic strategy to restore fertility of patients with severe Asherman's syndrome.

DESIGN

A step-by-step video demonstration of the technique with an emphasis on the key portions of the procedure. A detailed narrated description of the steps is provided.

SETTING

Tertiary care University Hospital.

INTERVENTIONS

Three patients were managed by hysteroscopy performed in the office setting without anesthesia. Case 1 is a 34-year-old woman with obstetrical history of first-trimester incomplete abortion treated with Dilation and Curettage (D&C), followed by a tubal ectopic pregnancy treated with laparoscopic partial salpingectomy and a subsequent pregnancy on the tubal stump treated with uterine artery embolization. Case 2 is a 40-year-old woman with history of tubal ectopic pregnancy treated with salpingectomy, a surgical first-trimester voluntary termination of pregnancy with D&C and a full term vaginal delivery complicated with retained products of conception that were removed with D&C. Case 3 is a 35-year-old woman with two previous first-trimester spontaneous miscarriages both treated with D&C. Case 1 and 3 were treated using miniaturized mechanical instruments only; in case 2, miniaturized mechanical instruments and the 15 Fr bipolar mini-resectoscope were used. Preoperative 2D and 3D ultrasound were used to predict the complexity of the cases and to guide the surgeon during the procedure. Intrauterine lysis of adhesions was concluded when both tubal ostia were visualized, and the uterine cavity was determined to have adequate shape and volume. At the end of the procedures, hyaluronic acid-based gel was applied to prevent new intrauterine adhesion formation. Two weeks after the initial procedure, a second look diagnostic hysteroscopy was performed. Only one patient (#1) needed additional lysis of adhesions; in this case, at the end of the procedure, a Word catheter was inserted as a barrier method for the prevention of adhesion formation. Eight weeks later, the word catheter was removed, and additional lysis of adhesions was performed. All the surgical procedures were performed without complication, and a healthy endometrium was observed at the second look hysteroscopy, in all the three patients. All 3 patients conceived after the procedure. Pregnancy was achieved after one IVF cycle with the transfer of one frozen embryo in case 1 and spontaneously in cases 2 and 3. Patient 1 was delivered by elective caesarean section due to placenta previa, while the other two patients had normal vaginal deliveries. Patient 1 had Retained Products of Conception requiring hysteroscopic removal using a 27 Fr Resectoscope.

CONCLUSION

When using innovative miniaturized instruments and adequate surgical technique, hysteroscopic lysis of adhesions is a feasible and effective in-office strategy to restore fertility in patients with severe Asherman's syndrome. The use of 2D and 3D ultrasound played an important role in the preoperative workup of the patient with Asherman's syndrome.

Pharmacological and non-pharmacological pain relief for office hysteroscopy: an up-to-date review

In-office hysteroscopy is considered the standard technique for visualization of the uterine cavity and the diagnosis of intrauterine pathologies. Moreover, nowadays, it is possible to treat a vast number of intracavitary diseases in the office, without the need for the inpatient setting. However, in some cases, pain might occur, and this is the most common reason for not completing the procedure. Over the last 20 years, many efforts have been carried out to miniaturize the instrumentation and to improve the techniques in order to avoid discomfort. Nonetheless, hysteroscopy still provokes distress for many patients. For this reason, pharmacological and non-pharmacological treatments for intraoperative and postoperative pain relief have been widely used for in-office hysteroscopy, with different results in various groups of women. The purpose of this review was to analyze the current literature on pharmacological aids (non-steroidal anti inflammatory drugs, cyclooxygenase-2 inhibitors, antispasmodics, local anesthetics, prostaglandins, opioids) and non-pharmacological interventions (transcutaneous electrical nerve stimulation, uterine stretching, uterine pressure, warming of distension medium, hypnosis, music, vocal-local) and to evaluate their impact on the relief from pain experienced during in-office hysteroscopy.
