The seamless integration of robotic systems with artificial intelligence, image-guided surgery, and telesurgery presents undeniable advantages, enhancing the precision and effectiveness of surgical interventions. What is new?: This article provides a guide to the robotic platforms available on the market and those in development for gynaecologists interested in robotic surgery.

Laparoscopic transabdominal cerclage in a pregnant woman after fertility-sparing treatment for early-stage cervical cancer: an operative technique in ten steps.

Introduction: Fertility-sparing treatments are increasingly used in patients with early-stage cervical cancer. The residual shortened cervix might increase the risk of preterm birth. When a vaginal cerclage is not technically feasible, a laparoscopic transabdominal cerclage (LAC) could be offered before or after conception. In this article, we show how to safely perform a post-conceptional LAC in patients with insufficient residual cervical length for vaginal cerclage. Methods: A 34-year-old patient in the twelfth week of gestation who previously underwent repeated conisation for cervical cancer FIGO stage IA1 in 2021 was referred for cervical stenosis, which required a subsequent vaginal tracheoplasty. She became pregnant 3 months later. Ultrasound monitoring of the cervix showed a 15 mm cervical length. A step-by-step LAC in a pregnant woman was performed. Results: The Doppler velocimetry of the uterine arteries at the end of the procedure was normal. No intraoperative or postoperative complications were reported. The estimated blood loss was 100 mL and the total operative time of 120 min. The patient was discharged on the third postoperative day. A caesarean section was performed at 36 weeks of gestation for spontaneous contractions with excellent obstetric (male, 2860 gr) and neonatal outcomes. Conclusion: LAC in pregnancy, although made more difficult due to the size of the uterus, is a safe and feasible procedure combining the advantages of minimally invasive surgery with excellent obstetric result. Learning Objective: In this video is shown how to perform a post-conceptional transabdominal laparoscopic cerclage in a young woman with no sufficient cervical length for a vaginal approach.

En-block butterfly excision of posterior compartment deep endometriosis: The first experience with the new surgical robot Hugo™ RAS.

Background: Minimally invasive surgery is the gold standard treatment for deep endometriosis when medical management fails. In selected cases, such as when bowel or urinary tract are involved, robotic assisted surgery can be useful due to its characteristics of high dexterity and manoeuvrability. This is the first case of robotic en-bloc excision of posterior compartment deep endometriosis performed with the new HugoTM RAS system. Objective: The purpose of this video article is to show for the first time the feasibility of bowel surgery for deep endometriosis with this new robotic device. Materials and Methods: A 24-years-old woman affected by severe dysmenorrhea, chronic pelvic pain, dyschezia and dyspareunia underwent to deep endometriosis excision using the new robotic platform HugoTM RAS system at the Unit of Gynaecological Oncology, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy. Main outcome measures: Intraoperative data, docking set up, post-operative outcomes up to three months follow up were evaluated. Results: The surgical procedure was carried out without intra-operative or post-operative complications, operative time (OT) was 200 minutes, while docking time was 8 minutes. No system errors or faults in the robotic arms were registered. Post-operative complete disease-related symptoms relief was reported. Conclusion: According to our results, the introduction of this new robotic platform in the surgical management of deep endometriosis seems to be feasible, especially in advanced cases. However, further studies are needed to demonstrate the benefits of this surgical system and the advantages of robotic surgery compared to laparoscopy in this subset of patients.

Haemorrhoidal haemodynamic changes in patients with haemorrhoids treated using Doppler-guided dearterialization.

BACKGROUND: Arterial hyperflow to haemorrhoids has been implicated as a possible pathophysiological co-factor in haemorrhoidal disease. The purpose of this study was to investigate how transanal haemorrhoidal dearterialization (THD) can influence haemodynamic parameters at the level of the haemorrhoidal piles. METHODS: Patients with grade III haemorrhoids selected for THD between July and December 2018 were evaluated using endoanal ultrasonography and colour Doppler imaging at the level of internal haemorrhoids before and 1 year after the surgical procedure. Peak systolic velocity, pulsatility index, resistivity index, acceleration time, and end-diastolic velocity were measured, and preoperative and postoperative values compared. Symptom severity was measured using a symptom-based questionnaire (score range 0-20). RESULTS: Of 21 patients treated, 17 completed the study. Compared with preoperative values, postoperative peak systolic velocity (mean(s.d.) 18.7(1.1) versus 10.3(0.4) cm/s; P < 0.05), pulsatility index (5.5(0.3) versus 2.8(0.4); P < 0.050), and resistivity index (1.0(0.2) versus 0.8(0.5); P < 0.050) decreased significantly, whereas acceleration time increased significantly (65.6(3.6) versus 83.3(4.7) cm/s2; P < 0.050); end-diastolic velocity did not change (1.9(0.2) versus 2.0(0.4); P = 0.753). Symptoms disappeared or had improved significantly in all patients by 1 year after surgery. The mean(s.d.) total symptom severity score decreased from 15.8(1.1) to 1.2(1.6) (P < 0.001). CONCLUSION: THD affects the main haemodynamic parameters at the level of internal haemorrhoids and is associated with a decrease in arterial hyperflow.

Simple fistula-in-ano: is it all simple? A systematic review.

BACKGROUND: Simple anal fistula is one of the most common causes of proctological surgery and fistulotomy is considered the gold standard. This procedure, however, may cause complications. The aim of this systematic review was to assess the surgical treatment of simple anal fistula with traditional and sphincter-sparing techniques. METHODS: A literature research was performed using PubMed, Cochrane, and Google Scholar to identify studies on the surgical treatment of simple anal fistulas. Observational studies and randomized clinical trials were included. We assessed the risk of bias of included studies using the Jadad scale for randomized controlled trials, and the MINORS Scale for the remaining studies. RESULTS: The search returned 456 records, and 66 studies were found to be eligible. The quality of the studies was generally low. A total of 4883 patients with a simple anal fistula underwent a sphincter-cutting procedure, mainly fistulotomy, with a weighted average healing rate of 93.7%, while any postoperative continence impairment was reported in 12.7% of patients. Sphincter-sparing techniques were adopted to treat 602 patients affected by simple anal fistula, reaching a weighted average success rate of 77.7%, with no study reporting a significant postoperative incontinence rate. The postoperative onset of fecal incontinence and the recurrence of the disease reduced patients' quality of life and satisfaction. CONCLUSIONS: Surgical treatment of simple anal fistulas with sphincter-cutting procedures provides excellent cure rates, even if postoperative fecal incontinence is not a negligible risk. A sphincter-sparing procedure could be useful in selected patients.
