Outcomes of conventional and advanced energy devices in laparoscopic surgery: a systematic review

Applications of different energy devices in laparoscopic and robotic gynecological surgery: a systematic review

PURPOSE

This study aims to evaluate and summarize the existing literature regarding the safety, efficacy, and outcomes of various energy sources in minimally invasive gynecological surgeries.

METHODS

A systematic review was conducted by searching the PubMed/MEDLINE, Cochrane Library, and Web of Science databases. We included studies that compared different energy sources used in laparoscopic and robotic gynecological surgeries, focusing on their advantages and complications. 37 studies were ultimately included in this review.

RESULTS

Among the 37 studies, 24 were randomized controlled trials, 11 were retrospective studies, and 1 was prospective. In laparoscopic procedures, advanced energy sources were associated with reduced intraoperative blood loss and shorter operative times. Specifically, ultrasonic devices demonstrated significantly less thermal damage and facilitated easier postoperative histologic assessment of lymph nodes compared to conventional electrosurgery. In robotic assisted surgeries, the literature reported shorter hospital stays and reduced thermal injury during colpotomy when utilizing laser energy. No significant differences were observed in other perioperative outcomes across both minimally invasive approaches.

CONCLUSION

Advanced energy devices may offer advantages in gynecological minimally invasive surgery, particularly in minimizing tissue trauma and enhancing surgical precision. However, evidence on outcomes such as lateral thermal spread and tissue healing remains limited and inconsistent. Further high-quality comparative studies are needed to clarify the clinical implications of each energy source and guide optimal instrument selection, especially in robotic assisted procedures.

vNOTES as a salvage method for adnexectomy and high uterosacral ligament suspension after vaginal hysterectomy under epidural anesthesia: A feasibility and safety study

OBJECTIVE

To evaluate the feasibility and safety of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) for performing adnexectomy and high uterosacral ligament suspension (HUSLS) after vaginal hysterectomy (VH) under epidural anesthesia.

METHOD

This was a retrospective case series of 42 women who underwent VH for stage II or greater apical prolapse according to pelvic organ prolapse quantification (POP-Q); however, adnexectomy could not performed and replace the vNOTES technique. The procedure continued with vNOTES adnexectomy and bilateral HUSLS under epidural anesthesia. Patient demographics, operation outcomes, and short-term and long-term complications were analyzed. Patients' quality of life was assessed with the Pelvic Floor Distress Inventory-20 (PFDI-20) at the 24-month visit.

RESULTS

vNOTES procedures were performed successfully under epidural anesthesia in all patients. One patient was converted to general anesthesia due to ureter injury. The mean age of the patients was 54 years. The mean operating time for all procedures was 55 min (range 42-122). The mean blood loss was 90 ml. All patients ambulated 6 h later. The mean pain score 24 h later according to the visual analog scale (VAS) was 2 (range 0-5). The median length of hospital stay was 1 night (range 1-3). There were no complications or morbidities during the postoperative period. Each POP-Q score significantly improved at the 6-month visit (p < 0.05). While the preoperative mean total PFDI-20 score was 20.4 ± 6.6, it significantly decreased to 8 ± 1.2 24 months later (p < 0.05).

CONCLUSION

The vNOTES technique is a good option when adnexectomy can not be performed after VH. The procedure can be completed safely under epidural anesthesia by performing HUSLS for apical support along with adnexectomy. In this way, patients combine the advantages of scarless minimally invasive surgery with the advantages of epidural anesthesia. Introductıon.

Does Frequent Use of Advanced Energy Devices Improve Hysterectomy Outcomes?

Background and Objectives: The objective of this study was to assess the efficient use of advanced energy devices by examining the impact of their usage frequency on surgical outcomes of total laparoscopic hysterectomies. Materials and Methods: A retrospective study was conducted between 2020 and 2023 by a single surgeon. The patients' medical records and surgical videos were reviewed. Cases were categorized into three groups based on the frequency of usage of advanced energy devices: Group 1 (≤10 uses), Group 2 (11-20 uses), and Group 3 (≥21 uses). The differences in blood loss, surgery time, and surgical outcomes among these groups were analyzed. This study was conducted as a single-center retrospective analysis. It included 126 patients who underwent total laparoscopic hysterectomy and provided informed consent for video recording. To evaluate the usage of advanced energy devices, anonymized surgical videos were reviewed, and outcomes were analyzed based on the frequency of usage of advanced energy devices. Results: The time required for surgery differed significantly among the three groups (p = 0.006). However, no significant differences were observed in the changes in hemoglobin levels or estimated blood loss (p = 0.255 and 0.053, respectively). Additionally, the application of hemostatic agents, the need for intraoperative or postoperative transfusions, and the use of intravenous hemostatic agents postoperatively showed no notable variation. Complication rates, including rates of hematoma, urinary tract injury, gastrointestinal injury, and infections necessitating reoperation, were also comparable. Conclusions: The findings suggest that the prudent and strategic use of advanced energy devices, rather than their frequent application, may improve surgical efficiency without increasing the risk of complications.

Plasma knife sphenopalatine artery cauterization via lateral nasal wall incision for posterior epistaxis

BACKGROUND

Endoscopic sphenopalatine artery cauterization (ESPAC) has become an important method to manage posterior epistaxis.

AIMS/OBJECTIVES

To investigate the application of plasma knife and lateral nasal wall incision in ESPAC in the treatment of posterior epistaxis.

MATERIAL AND METHODS

A retrospective study of 32 cases who underwent ESPAC for epistaxis was conducted. A vertical incision was made on the lateral nasal well to expose the sphenopalatine artery (SPA). The main branches of SPA were cauterized with a plasma knife or bipolar coagulation forceps. Cases were divided into plasma knife group (group PK) and bipolar group (group BP). The re-bleeding rates, operation time and the incidence of serious complication were compared between the two groups.

RESULTS

ESPAC was successfully completed via a lateral nasal wall incision without maxillary antrostomy in all cases. All the patients were followed-up for 3 months, no serious complication was reported. There was no significant difference in re-bleeding rates and incidence of serious complication between the two groups. The operation time of group PK was shorter than group BP.

CONCLUSIONS AND SIGNIFICANCE

Lateral nasal well incision without maxillary antrostomy is feasible for ESPAC. The application of a plasma knife may help to shorten the operation time.

Evaluation of the benefit of indocyanine green as an educational and practical tool for ureteral identification in laparoscopic pelvic surgery: a cross-sectional study

BACKGROUND

Indocyanine green (ICG) is a visible near-infrared fluorescent dye. Several studies have reported its benefit in identifying important anatomical structures, tissue vascularization, and sentinel lymph nodes in the case of tumors. Studies have shown that ICG is critical and safe in gynecologic surgeries. However, research on how ICG dye can help surgeons in laparoscopic surgeries correctly identify the course of the ureter has yet to be further investigated.

METHOD

This cross-sectional study enrolled 62 gynecology attending and resident surgeons who were asked to identify the course of the ureter on images of laparoscopic surgeries. The results were then compared with images in which ICG dye highlighted the course of the ureter. The purpose of this study was to detect the ability of surgical assistants and residents to adequately identify the course of the ureter in laparoscopic pelvic surgeries.

RESULTS

No statistically significant differences were found in terms of year of residency, years of experience, number of laparoscopic procedures attended, and correct identification of ureter course. ICG proved useful in identifying the correct ureteral trajectory.

CONCLUSIONS

ICG can be a valuable tool to improve the correct identification of ureters and improve surgical outcomes.

Impact of surgery on reproductive outcomes in women with deep endometriosis and proven presurgical infertility: Facts and controversies

In women with proven infertility and deep endometriosis (DE), optimal management is controversial. To date, there is no clear evidence on the association between infertility and different stages of rASRM, nor is there clear guidance from leading scientific societies for surgical treatment of DE patients. A comprehensive literature search was conducted on the main databases for English-language trials describing the effectiveness of surgery for DE in patients with proven infertility; 16 studies were deemed eligible for inclusion in this systematic review (CRD42024498888). Quantitative analysis was not possible because of the heterogeneity of the data. A descriptive summary of the results according to location of pathology, surgical technique used, and whether assisted reproductive technology (ART) was needed or not was provided. A total of 947 infertile women were identified, 486 of whom became pregnant, with an average pregnancy rate of 51.3%. Our review suggests that surgery can be of valuable help in improving reproductive outcomes by improving the results of ART. It has not been possible to reach robust conclusions on the outcomes of surgery based on the location of DE because of the heterogeneity of evidence available to date. Overall, although some data encourage first-line surgical management, further investigation is needed to determine its effective application before or after ART failure.

Global scientific production on gasless laparoscopy: a bibliometric analysis

Objectives

To characterize the bibliometric characteristics of the global scientific production of original research on gasless laparoscopy in the Web of Science Core Collection (WoSCC) platform.

Materials and methods

A bibliometric study of original articles published up to the year 2023 was carried out. Articles were included following the selection criteria in the Rayyan web application, indexed in the Scopus database. The bibliometric analysis was performed using the Bibliometrix program in the R programming language and VOSviewer. The bibliometric characteristics evaluated were articles, journals, citations, publications, ten most mentioned articles, journals with the highest number of publications, authors and institutional affiliations; and cooccurrence of terms.

Results

A total of 223 publications were included, with the highest number of articles being published in the years 1999 and 2014. The publication with the most citations was found to be a randomized trial by Galizia G in 2001 with 132 citations. We identified 846 authors involved in the production of articles on gasless laparoscopy, with Nakamura H being the most productive author with 15 articles between the years 2007 and 2020, followed by Takeda A and Imoto S, all three affiliated with "Gifu Prefectural Tajimi Hospital". The country with the highest production was Japan with 64 publications, followed by China and Italy with 46 and 18 publications, respectively. In the top 10 journals with the highest number of publications, "Surgical Endoscopy-Ultrasound and Interventional Techniques" is in first place with 20 articles published on gasless laparoscopy; in addition, most of these are located in Q1 and Q2. Regarding the terms or keywords, it was found that the initial studies had terms related to the disadvantages of pneumoperitoneum and later focused on more specific topics of the application of gasless laparoscopy.

Conclusions

Production on gasless laparoscopy has stagnated, with the topics of interest currently being its application in new, less invasive techniques. The most productive countries are found in the Asian and European continents, with little information collected in Latin America. This fact makes it necessary to increase the production of studies to promote this technique and its possible advantages.

Efficacy of letrozole for the treatment of tubal ectopic pregnancy: A meta-analysis

BACKGROUND

Tubal ectopic pregnancy (EP) is a life-threatening condition, especially if undiagnosed or misdiagnosed, tipically in low income countries and/or where women have limited access to health care. The current management protocol of tubal EP consists of either surgical management, or medical management with methotrexate. Recent studies, while few, have suggested that letrozole, an aromatase inhibitor, may play a role in the medical treatment of tubal EP.

OBJECTIVES

To evaluate the effectiveness of letrozole alone in the medical treatment of tubal EP.

SEARCH STRATEGY

Electronic databases were searched until 31 December 2023.

SELECTION CRITERIA

Retrospective or prospective studies reporting the treatment of tubal EP with letrozole alone were considered eligible for inclusion.

DATA COLLECTION AND ANALYSIS

Pooled results were expressed as OR with 95 %CI. Heterogeneity was assessed using Higgins I2. Subgroup analysis was performed to compare outcomes according to time after intervention. Subgroup differences were checked through χ2 test.

RESULTS

A total of 152 patients were included. Seventy-nine patients (51.97 %) were treated with letrozole, 39 patients (16.54 %) with methotrexate, and 34 patients (31.49 %) underwent surgical treatment. Pooled data analysis supports the consistency of the effect of letrozole in reducing β-hCG over time at a comparable rate among studies, and that treatment with letrozole is superior to surgery and has the same efficacy as methotrexate. However, all the included studies were judged at high risk of bias in terms of study design, sample representativeness, and sampling technique. Furthermore, short and long term side effects were not reported in any of the included studies.

CONCLUSIONS

Letrozole is a promising alternative to methotrexate and surgical therapy in the treatment of tubal EP. Although this meta-analysis suggests efficacy and low hazard of the drug and encourages its application, the data available today remain extremely sparse, which weakens any claims that can be made, and is not sufficient to assert that letrozole is safe and effective in the treatment of EPs. There is an absolute need for randomized studies with accurate patient selection, fixed doses, large sample sizes, and reporting of short- and long-term side effects to refute or confirm this assumption.

Diagnosis and Management of Pelvic Congestion Syndrome: Comprehensive Review

BACKGROUND

Pelvic congestion syndrome (PCS) is a poorly understood condition that can be associated with chronic pelvic pain and could impact quality of life. The diagnosis is often made by exclusion of other causes of pelvic pain.

OBJECTIVE

The purpose of our review was to provide an update on the etiology, anatomy, physiology, identification, and the therapeutic management of PCS.

METHOD

We conducted a literature review involving publications from 2003 to 2024 in PubMed, Elsevier, MEDLINE, as well as manual searches of primary and review articles using keywords such as "pelvic veins", "embolization", "venography", "pelvic congestion syndrome", and "chronic pelvic pain".

CONCLUSION

PCS remains poorly understood. Symptoms can be non-specific and difficult to distinguish from other diseases; yet it is an important cause of chronic pelvic pain in women. To date, there have been only a small number of randomized trials and high-level evidence is still lacking.

OUTLOOK

We call for an increased awareness of PCS and additional clinical studies in a large number of patients.

Comparison of the effect of ultrasounic-harmonic scalpel and electrocautery in the treatment of axillary lymph nodes during radical surgery for breast cancer

OBJECTIVE

To compare the efficacy of ultrasounic-harmonic scalpel and electrocautery in the treatment of axillary lymph nodes during radical surgery for breast cancer.

METHODS

A prospective study was conducted in the Department of Breast Surgery, Zhongda Hospital Affiliated to Southeast University. A total of 128 patients with pathologically confirmed breast cancer who were treated by the same surgeon from July 2023 to November 2023 were included in the analysis. All breast operations were performed using electrocautery, and surgical instruments for axillary lymph nodes were divided into ultrasounic-harmonic scalpel group and electrocautery group using a random number table. According to the extent of lymph node surgery, it was divided into four groups: sentinel lymph node biopsy, lymph node at station I, lymph node at station I and II, and lymph node dissection at station I, II and III. Under the premise of controlling variables such as BMI, age and neoadjuvant chemotherapy, the effects of ultrasounic-harmonic scalpel and electrocautery in axillary surgery were compared.

RESULTS

Compared with the electrosurgical group, there were no significant differences in lymph node operation time, intraoperative blood loss, postoperative axillary drainage volume, axillary drainage tube indwelling time, postoperative pain score on the day after surgery, and the incidence of postoperative complications (p>0.05).

CONCLUSION

There is no significant difference between ultrasounic-harmonic scalpel and electrocautery in axillary lymph node treatment for breast cancer patients, which can provide a basis for the selection of surgical energy instruments.

Use of Diode Laser in Hysteroscopy for the Management of Intrauterine Pathology: A Systematic Review

Background: Hysteroscopy currently represents the gold standard for the diagnosis and treatment of intrauterine pathologies. Recent technological progress has enabled the integration of diagnostic and operative time, leading to the "see and treat" approach. Diode laser technology is emerging as one of the most innovative and intriguing techniques in this context. Methods: A comprehensive search of the literature was carried out on the main databases. Only original studies reporting the treatment of intrauterine pathologies using diode laser were deemed eligible for inclusion in this systematic review (PROSPERO ID: CRD42023485452). Results: Eight studies were included in the qualitative analysis for a total of 474 patients undergoing laser hysteroscopic surgery. Eighty-three patients had female genital tract abnormalities, 63 had submucosal leiomyomas, 327 had endometrial polyps, and one patient had a scar pregnancy. Except for leiomyomas, whose technique already included two surgical times at the beginning, only seven patients required a second surgical step. Cumulative rates of intraoperative and postoperative complications of 2.7% and 0.6%, respectively, were reported. Conclusions: Diode laser through "see and treat" hysteroscopy appears to be a safe and effective method. However, additional studies with larger sample sizes and improved designs are needed to consolidate the evidence currently available in the literature.

Reproductive and oncologic outcomes in young women with uterine sarcoma undergoing fertility-sparing treatment: a systematic review

Background

Uterine sarcomas (US) are rare cancer of possible occurrence even in women of childbearing age. To date, total hysterectomy is the standard treatment in the early stages. The possibilities of carrying out fertility-sparing treatments (FST) to save the fertility of women with unfulfilled reproductive desires are described in the literature, but to date, they can only be considered experimental.

Objective

The aim of this systematic review was to evaluate the oncological and reproductive outcomes of women with different histological types of US undergoing FST.

Design

Systematic review.

Data sources and methods

Electronic databases were searched for English-language studies describing FST for US until January 31, 2024.

Results

Forty-five papers which met the abovementioned inclusion criteria, were included in the qualitative analysis. Quantitative analysis was not possible because of the heterogeneity of the data. A descriptive summary of the results according to the histotype of US was provided. Six hundred forty-one patients of childbearing age with US and undergoing FST. After treatment with FST, 89 (13.9%) disease recurrences and 107 (16.7%) pregnancies were recorded.

Conclusion

In selected cases of early-stage US, FST may be proposed. However, the patient must be informed of the real possibility of recurrence and potentially difficult achievement of pregnancy. Additional well-designed prospective studies and clinical trials are needed to address the knowledge gaps and enhance clinical decision-making in this population.
