Background and objectives: Laparoscopic surgeries in gynecologic field have been performed under general anesthesia (GA) due to the respiratory changes caused by pneumoperitoneum and Trendelenburg position. Therefore, this study aimed to compared general anesthesia and combined spinal and epidural anesthesia (CSEA) for gasless laparoscopic surgery in gynecologic field.

Methods: We matched patients with type of surgery who underwent gasless single port access (SPA) laparoscopic surgery under general anesthesia and CSEA. The medical records of 90 patients between March 1, 2018 and June 30, 2020 were reviewed. Gasless laparoscopic surgery was performed in all patients with a SPA using a J-shaped retractor.

Results: No significant differences were observed for age, body mass index, parity, and previous abdominal surgery between GA and CSEA groups. During operation under CSEA, six patients (20%) experienced nausea/vomiting. Hypotension (systolic blood pressure < 90 mmHg) was observed in five patients (16.7%). Intravenous analgesics was administrated in four of the patients (13.3%) who suffered from shoulder pain or abdominal discomfort. One patient developed bradycardia. The duration of hospital admission was shorter in the CSEA group than in the GA group (p = 0.014). There was no difference between the groups in terms of surgery type, surgical specific finding, operation time, estimated blood loss, laparotomy conversion rate and use of additional trocar. No major complications such as urologic, bowel, or vessel injuries were found in both groups.

Conclusions: CSEA is a safe and feasible technique for application in nonobese patients undergoing gasless laparoscopic surgery in gynecologic field.

Objective: To evaluate the efficacy of intracervical injection of liposomal bupivacaine for postoperative pain control among women undergoing minimally invasive supracervical hysterectomy.

Methods: A randomized double-blinded placebo-controlled trial of intracervical injection of combination liposomal bupivacaine and bupivacaine for postoperative pain among patients undergoing laparoscopic and robotic supracervical hysterectomy. Patients were enrolled between October 1, 2018 and April 30, 2019. The primary outcome was pain at 12 hours postoperatively using a numeric rating scale from zero to 10. Pain scores were also recorded pre-operatively, immediately postoperatively, at 12, 24, and 48 hours postoperatively. The secondary outcome was the number of patients who required opioid analgesic medications up to 48 hours postoperatively.

Results: Sixty participants were randomized into the control (n = 30) and intervention (n = 30) groups. Pain scores were 1 and 1.75 (p = 0.89) immediately postoperatively, 3 and 3.5 (p = 0.85) at 12 hours, 3.5 and 5 (p = 0.22) at 24 hours, and 2.75 and 4 (p = 0.18) at 48 hours for the control and intervention groups, respectively. Within the first 24 hours, 10 patients in the control and 14 patients in the intervention group used narcotics (p = 0.37). From the 24 to 48 hours window, 6 and 8 patients in the control and intervention groups used narcotics (p = 0.74), respectively.

Conclusion: There was no statistically significant difference in pain scores between patients receiving combination liposomal bupivacaine and bupivacaine intracervical block and those receiving placebo in the first 48 hours after surgery. There was no difference in analgesic use between the two study groups.

Background and objectives: To present the methods and outcomes of total laparoscopic hysterectomy with debulking surgery for large cervical fibroids.

Methods: This is a single-center study. Twenty-one women who underwent total laparoscopic hysterectomy between October 1, 2012 and November 30, 2020 for large cervical fibroids (diameter ≥10 cm) based on a diagnosis by magnetic resonance imagining were enrolled. Conventional total laparoscopic hysterectomy for large cervical fibroids was initially attempted. If this could not be completed, debulking surgery, such as enucleation of large cervical fibroids or cervical amputation, was performed during total laparoscopic hysterectomy.

Results: Total laparoscopic hysterectomy could be completed in all 21 patients with large cervical fibroids without blood transfusion. Conventional total laparoscopic hysterectomy was performed in four patients (19%), and 17 patients (81%) required debulking surgery at the time of total laparoscopic hysterectomy. The median diameter of the major axis of the cervical fibroid, uterine weight, intraoperative blood loss, and operative time were 12 cm, 750 g, 100 mL, and 191 min, respectively.

Conclusion: Total laparoscopic hysterectomy for large cervical fibroids, although minimally invasive, requires a high level of laparoscopic skill. However, our data suggests that total laparoscopic hysterectomy for large cervical fibroids can be feasible, with an acceptable level of blood loss, by performing debulking surgeries such as enucleation of large cervical fibroids or cervical amputation.

Background and objective: Postoperative urinary retention (POUR) is a common adverse event after inguinal hernia repair (IHR), with an incidence of up to 22.2%. The aim of this study is to determine if pre-operative transverse abdominis plane (TAP) block increases the incidence of POUR.

Methods: A retrospective review was performed for all patients who underwent IHR (open or laparoscopic) at this institution, from January 1, 2016 to December 31, 2017. Patients were divided into two groups: Patients that had a TAP block before surgery (group 1) and patients with no TAP block (group 2). Common demographics and comorbidities were collected along with postoperative outcomes and POUR incidence rates for every group to determine procedural influence.

Results: From 276 patients reviewed, 28.2% (N = 78) underwent TAP block before surgery. The patient cohort mean age was 61.1 ± 14.4 years. Most the interventions were laparoscopic (81.2%) and an overall POUR incidence rate of 7.6% (N = 21) was observed. Comparatively, common demographics and comorbidities were statistically similar for both groups, with the exception of type 2 diabetes mellitus (p = 0.049). Individually, group 1 and 2 presented POUR incidence rates of 14.1% and 5.05%, respectively. While intraoperative fluid administration, early readmission rate, and length were similar in both groups, there was a significant difference in POUR incidence rates (p = 0.01).

Conclusion: Patients undergoing TAP block during IHR might have an increased risk of developing POUR. Further larger, prospective, and randomized controlled studies are necessary to better assess these findings.

Background and objectives: The aim of this study was to demonstrate a detailed and elaborative step-wise laparoscopic surgical management technique of vault endometriosis.

Methods: A total of 5 patients were operated on for laparoscopic management of vault endometriosis performed at our center between January 1 2015 and December 31, 2019.

Results: There were no short or long term complications related to laparoscopic management of vault endometriosis with a satisfactory prognosis.

Conclusion: This analysis explains the descriptive methodology of assessment of patients and operative technique for vault endometriosis.

Background and objectives: The primary aim of this study is to assess the necessity of fundoplication for reflux in patients undergoing Heller myotomy for achalasia. The secondary aim is to assess the safety of the robotic approach to Heller myotomy.

Methods: This is a single institution, retrospective analysis of 61 patients who underwent robotic Heller myotomy with or without fundoplication over a 4-year period (January 1, 2015 - December 31, 2019). Symptoms were evaluated using pre-operative and postoperative Eckardt scores at < 2 weeks (short-term) and 4 - 55 months (long-term) postoperatively. Incidence of gastroesophageal reflux and use of antacids postoperatively were assessed. Long-term patient satisfaction and quality of life (QOL) were assessed with a phone survey. Finally, the perioperative safety profile of robotic Heller myotomy was evaluated.

Results: The long-term average Eckardt score in patients undergoing Heller myotomy without fundoplication was notably lower than in patients with a fundoplication (0.72 vs 2.44). Gastroesophageal reflux rates were lower in patient without a fundoplication (16.0% vs 33.3%). Additionally, dysphagia rates were lower in patients without a fundoplication (32.0% vs 44.4%). Only 34.8% (8/25) of patients without fundoplication continued use of antacids in the long-term. There were no mortalities and a 4.2% complication rate with two delayed leaks.

Conclusion: Robotic Heller myotomy without fundoplication is safe and effective for achalasia. The rate of reflux symptoms and overall Eckardt scores were low postoperatively. Great patient satisfaction and QOL were observed in the long term. Our results suggest that fundoplication is unnecessary when performing Heller myotomy.

Background and objectives: The scope of laparoscopic surgery has expanded to encompass hepatic resections, specifically hepatic hemangioma. The most serious intraoperative complication is bleeding, often requiring laparotomy. Because risk factors associated with such massive blood loss have not been well evaluated, the intent of this retrospective study was to analyze these risk factors associated with laparoscopic resection of hepatic hemangiomas.

Methods: From June 1, 2011 to January 31, 2021, 140 consecutive patients underwent laparoscopic surgery for hepatic hemangioma in our hospital. According to quantity of intraoperative blood loss, they were divided into massive (≥ 800 ml) and minor blood loss (< 800 ml) groups. Perioperative data were analyzed by univariate and multivariate analyses with logistic regression to identify the risk factors for potential massive blood loss during laparoscopic resection.

Results: There were 24 and 116 patients in the massive and minor blood loss groups, respectively. Of four risk factors significantly associated with massive blood loss by univariate logistic regression analysis (location of hemangioma in the liver, postcaval or hepatic venous compression, hilar compression, and body mass index exceeding 28) the multifactorial logistic model identified only location in the liver of the hemangioma as statistically (P = 0.012) associated with intraoperative massive blood loss.

Conclusions: Location of the hepatic hemangioma was the single statistically significant risk factor for massive blood loss during laparoscopic surgery for hepatic hemangioma. Of particular importance, location in Couinaud liver segments I, IVa, VII, and VIII necessitates precautions to mitigate the risk of massive blood loss.

Background and objectives: This study aims to characterize the utilization of minimally invasive myomectomy in the United States and to identify the patient and hospital factors associated with surgical approach to myomectomy.

Methods: This is a cross-sectional study using the National Inpatient Sample database. We extracted women aged 18-50 years who underwent open and minimally invasive (laparoscopic and robotic) myomectomy (MIM) from January 1, 2010-December 31, 2014. Descriptive statistics were obtained for patient and hospital characteristics. We then performed multivariable logistic regression to examine the association of patient (age, race, insurance status, median household income) and hospital (bed size, teaching status, for-profit status, census region, cases volume) characteristics with the likelihood of undergoing MIM.

Results: Of 114,850 myomectomy cases, 8,330 (7%) underwent MIM and 106,520 (93%) were open. Over time, the proportion of MIM remained very low and slightly decreased from 8.2% in 2010 to 6.1% in 2014 (p-for-trend: 0.001). Most hospitals performed few MIM per year, with 50% performing five or less, and 25% performing three or fewer per year. African American, Hispanic, and women of other races were less likely to undergo MIM compared to Caucasian women (adjusted odds ration [OR] 0.57, 95% confidence interval [CI] 0.50-0.64; 0.71, 95% CI 0.60-0.83; 0.62, 95% CI 0.52-0.74, respectively). Women in the West (adjusted odds ratio (aOR) 1.23, 95% CI 1.04-1.46) and Midwest (aOR 1.27, 95% CI 1.07-1.52) had higher odds of undergoing MIM.

Conclusion: MIM appears to be an underutilized modality, accounting for less than10% of myomectomies. This underutilization disproportionally affects minority women.

Background and objectives: The COVID-19 pandemic dramatically impacted gynecologic surgery. In March 2020, the American College of Surgeons recommended delay of all nonessential invasive procedures. This study characterizes the number and types of procedures performed during the peak pandemic.

Methods: A retrospective cohort study was performed. All patients undergoing gynecological surgery at a large academic hospital system from March 16, 2019 to July 31, 2019 and from March 16, 2020 to July 31, 2020 were evaluated. Data was stratified by three time periods corresponding to state and hospital policy changes. During period 1, no nonessential procedures were advised. During period 2, urgent procedures resumed. During period 3, full surgical reopening was achieved.

Results: In 2019, 1,545 gynecologic cases were performed compared with 942 cases in 2020 (39.0% decrease). There was a 73.6% decrease in cases over period 1, a 20.1% decrease over period 2, and a 2.9% increase over period 3. Cases performed by gynecologic oncologists in 2020 accounted for 58.1% of all gynecologic cases over period 1, 29.4% of cases over period 2, and 33.3% of cases over period 3. In 2020, hysterectomy was the most commonly performed procedure, while surgery for endometriosis and uterine fibroids had the greatest decrease in volume. Among emergency procedures, more surgery for ectopic pregnancy was performed in 2020 compared with 2019.

Conclusion: Many patients had significant delays in receiving gynecologic surgical care during the peak pandemic period. Further studies are indicated to determine the impact of delayed care on patients' quality of life and disease process.

Background: Most healthcare providers are unaware of the extraordinary opportunities for implementation in healthcare which can be enabled by 5G wireless networks. 5G created enormous opportunities for a myriad of new technologies, resulting in an integrated through 5G 'ecosystem'. Although the new opportunities in healthcare are immense, medicine is slow to change, as manifest by the paucity of new, innovative applications based upon this ecosystem. Thus, emerges the need to "avoid technology surprise" - both laparoscopic and robotic assisted minimally invasive surgery were delayed for years because the surgical community was either unaware or unaccepting of a new technology.

Database: PubMed (Medline) and Scopus (Elsevier) databases were searched and all published studies regarding clinical applications of 5G were retrieved. From a total of 40 articles, 13 were finally included in our review.

Discussion: The important transformational properties of 5G communications and other innovative technologies are described and compared to healthcare needs, looking for opportunities, limitations, and challenges to implementation of 5G and the ecosystem it has spawned. Furthermore, the needs in the clinical applications, education and research in medicine and surgery, in addition to the administrative infrastructure are addressed. Additionally, we explore the nontechnical challenges, that either support or oppose this new healthcare renovation. Based upon proven advantages of these innovative technologies, current scientific evidence is analyzed for future trends for the transformation of healthcare. By providing awareness of these opportunities and their advantages for patients, it will be possible to decrease the prolonged timeframe for acceptance and implementation for patients.
