Enhancing surgical performance: the role of robotic surgery in myomectomies, a systematic review and metanalysis

Examine the role, benefits, and limitations of robotic surgery in myomectomies compared to laparoscopic and open surgical approaches. This review sourced data from CENTRAL, Pubmed, Medline, and Embase up until May 1, 2023. Full articles comparing clinical outcomes of robotic myomectomy with open or laparoscopic procedures were included without language restriction. Initially, 2150 records were found. 24 studies were finally included for both qualitative and quantitative analyses. Two investigators independently assessed all reports following PRISMA guidelines. Meta-analysis was conducted using the software "Review Manager Version 5.4". Risk-of-bias was assessed using the Newcastle-Ottawa scale. Sensitivity analysis was conducted, when feasible. In a comparison between robotic and laparoscopic myomectomies, no significant difference was observed in fibroid weights and the size of the largest fibroid. Robotic myomectomy resulted in less blood loss, but transfusion rates were comparable. Both methods had similar complication rates and operative times, although some robotic studies showed longer durations. Conversion rates favored robotics. Hospital stays varied widely, with no overall significant difference, and pregnancy rates were similar between the two methods. When comparing robotic to open myomectomies, open procedures treated heavier and larger fibroids. They also had greater blood loss, but the robotic approach required fewer transfusions. The complication rate was slightly higher in open procedures. Open surgeries were generally faster, postoperative pain scores were similar, but hospital stays were longer for open procedures. Pregnancy rates were comparable for both robotic and open methods. Robotic surgery offers advancement in myomectomy procedures by offering enhanced exposure and dexterity, leading to reduced blood loss and improved patient outcomes.

The Feasibility and Safety of vNOTES Hysterectomy and Uterosacral Ligament Suspension: A Case Series

The transvaginal natural orifice transluminal endoscopic surgery (vNOTES) is a recently introduced surgical approach that is even less invasive than conventional laparoscopy or robotic surgery. We conducted this study to report our experience in vNOTES hysterectomy and uterosacral ligament suspension and determine the feasibility and safety of this approach. Surgeries on 23 women were performed by a single surgeon in 1 tertiary medical center. Patient demographics, perioperative data, and follow-up details of 23 women were collected prospectively. Average age was 56.7 ± 8.9 years. Median parity was 3. Nine patients were smokers, and 4 patients had diabetes. Median stage of prolapse was 3. One patient had extensive adhesions, and after vNOTES hysterectomy was completed, decision was made to perform uterosacral suspension by conventional vaginal access. Another patient had intraoperative identification by cystoscopy of unilateral kinking of the ureter that was resolved after the most distal uterosacral stitch was released. Mean uterine weight was 271.9 ± 131.9 g. Average estimated blood loss was 85.22 ± 55.6 mL. Median length of stay in the hospital was 1 day. Only 1 patient had intermittent voiding postoperatively and required an indwelling catheter for 3 days. Hysterectomy and uterosacral ligament suspension when performed via vNOTES is a safe and feasible procedure. Large prospective trials are on the way to continue shedding light on this new surgical modality.

The efficacy of force of stream assessment for post-operative catheter management: a retrospective cohort study

INTRODUCTION AND HYPOTHESIS

Postoperative urinary retention is common after urogynecologic procedures. Our objective is to determine the efficacy of force of stream (FOS) assessment without a visual analog scale for postoperative catheter management.

METHODS

We conducted a retrospective cohort study of 110 women undergoing an inpatient gynecologic procedure. They were asked to subjectively assess FOS after surgery without a visual analog scale. If it was 50% or better than the usual preoperative void, they were discharged home without a catheter. If < 50%, the catheter was replaced and the patients were sent home and asked to follow up in 3 to 5 days for another void trial.

RESULTS

Average age was 56.9 ± 10.2 years; 63.6% underwent surgery for pelvic organ prolapse, 23.6% underwent sling for urinary incontinence, and 12.7% underwent a combination of both. Force of stream was > 50% in 93.6% of the patients; 6.4% had force of stream < 50% and hence were discharged home with a Foley catheter. Only two patients (1.8%) were discharged without a Foley catheter and returned to the emergency department for signs of urinary retention. Sensitivity, specificity, positive and negative predictive values were 77.8%, 100%, 100% and 98.1%, respectively.

CONCLUSION

The subjective assessment of flow of stream is a reliable and safe method to assess postoperative voiding. Given it is less invasive than backfilling the bladder and easier than using a bladder scan, it should be the primary method to assess postoperative voiding.

The Beirut Port Explosion Injuries and Lessons Learned: Results of the Beirut Blast Assessment for Surgical Services (BASS) Multicenter Study

OBJECTIVE

This multicenter study aims to describe the injury patterns, emergency management and outcomes of the blast victims, recognize the gaps in hospital disaster preparedness, and identify lessons to be learned.

SUMMARY BACKGROUND DATA

On August 4th, 2020, the city of Beirut, Lebanon suffered the largest urban explosion since Hiroshima and Nagasaki, resulting in hundreds of deaths and thousands of injuries.

METHODS

All injured patients admitted to four of the largest Beirut hospitals within 72 hours of the blast, including those who died on arrival or in the emergency department (ED), were included. Medical records were systematically reviewed for: patient demographics and comorbidities; injury severity and characteristics; prehospital, ED, operative, and inpatient interventions; and outcomes at hospital discharge. Lessons learned are also shared.

RESULTS

An estimated total of 1818 patients were included, of which 30 died on arrival or in the ED and 315 were admitted to the hospital. Among admitted patients, the mean age was 44.7 years (range: 1 week-93 years), 44.4% were female, and the median injury severity score (ISS) was 10 (5, 17). ISS was inversely related to the distance from the blast epicenter (r = --0.18, P = 0.035). Most injuries involved the upper extremities (53.7%), face (42.2%), and head (40.3%). Mildly injured (ISS <9) patients overwhelmed the ED in the first 2 hours; from hour 2 to hour 8 post-injury, the number of moderately, severely, and profoundly injured patients increased by 127%, 25% and 17%, respectively. A total of 475 operative procedures were performed in 239 patients, most commonly soft tissue debridement or repair (119 patients, 49.8%), limb fracture fixation (107, 44.8%), and tendon repair (56, 23.4%). A total of 11 patients (3.5%) died during the hospitalization, 56 (17.8%) developed at least 1 complication, and 51 (16.2%) were discharged with documented long-term disability. Main lessons learned included: the importance of having key hospital functions (eg, laboratory, operating room) underground; the nonadaptability of electronic medical records to disasters; the ED overwhelming with mild injuries, delay in arrival of the severely injured; and the need for realistic disaster drills.

CONCLUSIONS

We, therefore, describe the injury patterns, emergency flow and trauma outcome of patients injured in the Beirut port explosion. The clinical and system-level lessons learned can help prepare for the next disaster.

Aspirin for Endometrial Preparation in Patients Undergoing IVF: A Systematic Review and Meta-analysis

OBJECTIVE

To investigate the effect of aspirin on IVF success rates when used as an adjuvant treatment for endometrial preparation.

DATA SOURCES

Relevant publications were comprehensively selected from PubMed, MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) up to November 15, 2020.

STUDY SELECTION

Randomized controlled trials (RCTs) and retrospective cohort studies that used aspirin as an adjuvant treatment for endometrial preparation and reported subsequent pregnancy outcomes were included. Studies were excluded if aspirin was used before and/or during ovarian stimulation.

DATA EXTRACTION AND SYNTHESIS

This systematic review and meta-analysis included a total of 7 studies. Risk of bias assessment was based on the methodology and categories listed in the Cochrane Handbook for the RCTs and the Newcastle-Ottawa scale for the retrospective studies. The primary outcome was live birth rate. Summary measures were reported as odds ratios (ORs) with 95% confidence intervals (CIs). There was significant evidence that aspirin for endometrial preparation improved live birth rates (OR  1.52; 95% CI   1.15-2.00). No effect was noted for clinical pregnancy rates (OR  1.37; 95% CI   1.00-1.87); however, aspirin was associated with improved pregnancy rates in a subgroup analysis of patients receiving oocyte donation (OR 2.53; 95% CI 1.30-4.92) and in the sensitivity analysis (OR 1.3; 95% CI   1.02-1.66). No effect of aspirin was found for implantation or miscarriage rates (OR 1.31; 95% CI  0.51-3.36 and OR 0.41; 95% CI  0.02-7.42, respectively).

CONCLUSION

These findings support a beneficial effect of aspirin for endometrial preparation on IVF success rates, mainly live birth rates, outside the context of ovarian stimulation. However, this evidence is based on poor quality data and needs to be confirmed with high-quality RCTs.
