[Trends of minimally invasive surgical techniques in endometrial carcinoma at the National Institute of Oncology (2016-2024)]. / A minimálisan invazív sebészeti technikák trendjei endometriumkarcinómában az Országos Onkológiai Intézetben (2016­2023).

The aim of this study was to analyze the trends and clinical outcomes of minimally invasive surgical techniques in the treatment of endometrial carcinoma at the National Institute of Oncology, Department of Gynecology, from 2016 to 2023. This retrospective study included patients with endometrial carcinoma stages I-IV who underwent primary surgical treatment between 2016 and 2023. The techniques analyzed were total laparoscopic hysterectomy (TLH), robotic- assisted hysterectomy (RAH), and total abdominal hysterectomy (TAH). A total of 1127 patients were included. The number of minimally invasive surgeries increased significantly: in 2016, there were 69 laparotomies and 1 TLH, while in 2023, there were 57 laparotomies, 19 TLHs and 123 robotic-assisted hysterectomies. As a conclusion, the use of minimally invasive techniques significantly increased in the treatment of endometrial carcinoma. The entire team, including anesthesiologists, gained experience in managing morbidly obese patients, enabling safe minimally invasive surgeries.

Evolution of minimally invasive liver surgery in France over the last decade.

BACKGROUND: Despite evidence of benefits on postoperative outcomes, minimally invasive liver surgery (MILS) had a very low diffusion up to 2014, and recent evolution is unknown. Our aim was to analyze the recent diffusion and adoption of MILS and compare the trends in indications, extent of resection, and institutional practice with open liver surgery (OLS). METHODS: We analyzed the French nationwide, exhaustive cohort of all patients undergoing a liver resection in France between January 1, 2013 and December 31, 2022. Average annual percentage changes (AAPC) in the incidence of MILS and OLS were compared using mixed-effects log-linear regression models. Time trends were analyzed in terms of extent of resection, indication, and institutional practice. RESULTS: MILS represented 25.2% of 74,671 liver resections and year incidence doubled from 16.5% in 2013 to 35.4% in 2022. The highest AAPC were observed among major liver resections [+ 22.2% (19.5; 24.9) per year], primary [+ 10.2% (8.5; 12.0) per year], and secondary malignant tumors [+ 9.9% (8.2; 11.6) per year]. The highest increase in MILS was observed in university hospitals [+ 14.7% (7.7; 22.2) per year] performing 48.8% of MILS and in very high-volume (> 150 procedures/year) hospitals [+ 12.1% (9.0; 15.3) per year] performing 19.7% of MILS. OLS AAPC decreased for all indications and institutions and accelerated over time from - 1.8% (- 3.9; - 0.3) per year in 2013-2018 to - 5.9% (- 7.9; - 3.9) per year in 2018-2022 (p = 0.013). CONCLUSIONS: This is the first reported trend reversal between MILS and OLS. MILS has considerably increased at a national scale, crossing the 20% tipping point of adoption rate as defined by the IDEAL framework.

Trends in American Plastic Surgery Procedures (2005-2019): Observing the Growth Rate of Maxillofacial Surgery and Cosmetic Minimally Invasive Procedures in ASPS Data.

BACKGROUND: This study explores the dynamic changes in plastic surgery practices, focusing on the growth rates across different subcategories, particularly highlighting the trends in the United States. OBJECTIVES: To analyze evolving trends in plastic surgery using statistical methods, providing insights into the changes and growth patterns in various segments over time. MATERIALS AND METHODS: Utilizing data from 2005 to 2019 from the American Society of Plastic Surgeons, the authors, conducted a comprehensive statistical analysis using the SPSS program to investigate trends in plastic surgery procedures. RESULTS: Our analysis revealed no significant differences in year-on-year growth rates between cosmetic and reconstructive surgery. However, in reconstructive surgery subcategories, maxillofacial surgery showed the highest mean growth rate at 11.61%, though this was not statistically significant. In cosmetic minimally invasive procedures, soft tissue filler injections and botulinum toxin A injections experienced notably higher growth trends compared with microdermabrasion. CONCLUSION: The findings suggest that practitioners considering a career in plastic surgery should not focus solely on choosing between reconstructive and cosmetic surgery. Recognizing substantial growth in cosmetic minimally invasive procedures, especially botulinum toxin A injections and fillers, is vital for making informed career decisions.

Trends and Costs of Minimally Invasive Surgery for Kidney Cancer in the US: A Population-based Study.

OBJECTIVE: To analyze temporal trends and costs associated with the use of minimally invasive surgery (MIS) for kidney cancer in the US over the past decade. To examine the impact of social determinants of health (SDOH) on perioperative outcomes. METHODS: The PearlDiver Mariner, a national database of insurance billing records, was queried for this retrospective observational cohort analysis. The MIS population was identified and stratified according to treatment modality, using International Classification of Diseases and current procedural terminology codes. SDOH were assessed using International Classification of Diseases codes. Negative binomial regression was used to evaluate the overall number of renal MIS and Cochran-Armitage tests to compare the utilization of different treatment modalities, over the study period. Multivariable logistic regression analysis identified predictors of perioperative complications. RESULTS: A total of 80,821 MIS for kidney cancer were included. Minimally invasive partial nephrectomy adoption as a fraction of total MIS increased significantly (slope of regression line, reg. = 0.026, P <.001). Minimally invasive radical nephrectomy ($26.9k ± 40.9k) and renal ablation ($18.9k ± 31.6k) were the most expensive and cheapest procedures, respectively. No statistically significant difference was observed in terms of number of complications (P = .06) and presence of SDOH (P = .07) among the treatment groups. At multivariable analysis, patients with SDOH undergoing minimally invasive radical nephrectomy had higher odds of perioperative complications, while renal ablation had a significantly lower probability of perioperative complications. CONCLUSION: This study describes the current management of kidney cancer in the US, offering a socioeconomic perspective on the impact of this disease in everyday clinical practice.

Trends in minimally invasive and open inguinal hernia repair: an analysis of ACGME general surgery case logs.

BACKGROUND: Groin hernia repair is one of the most commonly performed surgical procedures and is often performed by surgical interns and junior residents. While traditionally performed open, minimally invasive (MIS) groin hernia repair has become an increasingly popular approach. The purpose of this study was to determine the trends in MIS and open inguinal and femoral hernia repair in general surgery residency training over the past two decades. METHODS: Accreditation Council for Graduate Medical Education (ACGME) national case log data of general surgery residents from 1999 through 2022 were reviewed. We collected means and standard deviations of open and MIS inguinal and femoral hernia repairs. Linear regression and ANOVA were used to identify trends in the average annual number of open and MIS hernia repairs logged by residents. Cases were distinguished between level of resident trainees: surgeon-chief (SC) and surgeon-junior (SJ). RESULTS: From July 1999 to June 2022, the average annual MIS inguinal and femoral hernia repairs logged by general surgery residents significantly increased, from 7.6 to 47.9 cases (p < 0.001), and the average annual open inguinal and femoral hernia repairs logged by general surgery residents significantly decreased, from 51.9 to 39.7 cases (p < 0.001). SJ resident results were consistent with this overall trend. For SC residents, the volume of both MIS and open hernia repairs significantly increased (p < 0.001). CONCLUSIONS: ACGME case log data indicates a trend of general surgery residents logging overall fewer numbers of open inguinal and femoral hernia repairs, and a larger proportion of open repairs by chief residents. This trend warrants attention and further study as it may represent a skill or knowledge gap with significant impact of surgical training.

The Future of Minimally Invasive Spine Surgery.

Minimally invasive spine surgery (MISS) is an important option for spinal operations, with advantages including rapid recovery and preservation of normal structures. As the number of geriatric patients is increasing, the role of MISS might expand in the future. MISS techniques and approaches continue to be developed, and recent trends in MISS development include the refinement of surgical approaches and techniques, as well as systems related to newly developed techniques, rather than spinal implants. Among the various techniques for MISS, endoscopic spine surgery, including uniportal and biportal endoscopic approaches, is the focus of vigorous research efforts that may lead to further expansion of the indications of endoscopic spine surgery. Endoscopic spine surgery will be an important part of spine surgery. Lateral lumbar interbody fusion and endoscopic lumbar interbody fusion may play meaningful roles in the MISS fusion area. Robotics and augmented reality are also likely to be important technological modalities in spine surgery in the future.

Perspectives of Gynecologic Oncologists on Minimally Invasive Surgery During COVID-19 Pandemic: A Turkish Society of Minimally Invasive Gynecologic Oncology (MIJOD) Survey.

BACKGROUND: To evaluate gynecologic oncologists' trends and attitudes towards the use of Minimally invasive surgery (MIS) in active period of the COVID-19 pandemic in Turkey. METHODS: Online national survey sent to members of Turkish Endoscopy Platform consisting of six sections and 45 questions between the dates 1-15 June 2020 in Turkey to explore their surgical practice during the pandemic in three hospital types: Education and research hospital/university hospital, state hospital and private Hospital. Participants were gynecologic oncologists who are members of Turkish Endoscopy Platform. RESULTS: Fifty-eight percent of participants canceled all operations except for cancer surgeries and emergent operations. About a quarter of participants (28%) continued to operate laparoscopically and/or robotically. For the evaluation of the suspected adnexial mass (SAM) 64% used laparotomy and only 13 % operated by laparoscopy (L/S). For the management of low-risk early-stage endometrial cancer only fifth of the participants preferred to perform L/S. For endometrial cancer with high-intermediate risk factors more than half of participants preferred complete staging with laparotomy. For advanced stage ovarian cancer, one-fifth of the participants preferred to perform an explorative laparotomy, whilst 15 % preferred diagnostic laparoscopy to triage the patients for either NACT or cytoreductive surgery. On the contrary 41 % of participants chose to have cytology by paracentesis for neo-adjuvant chemotherapy (NACT). Gynecologic oncologists with >10 years L/S experience used MIS more for SAM. Furthermore, experienced surgeons used L/S more for endometrial cancer patients. In busy COVID hospitals, more participants preferred laparotomy over L/S. CONCLUSION: Use of MIS decreased during the pandemic in Turkey. More experienced surgeons continued to perform MIS. Surgical treatment was the preferred approach for SAM, early-stage endometrial cancer.  However, NACT was more popular compared to radical surgery.

Trends in the Use of Minimally Invasive Adnexal Surgery in the United States.

OBJECTIVE: To examine the utilization of minimally invasive adnexal surgery, including ovarian cystectomy and oophorectomy, among women with benign gynecologic diseases and compare the associated morbidity and mortality of minimally invasive and open surgery. METHODS: Women with benign ovarian pathology who underwent an ovarian cystectomy or oophorectomy from 2016 through 2018 in the Nationwide Ambulatory Surgery Sample and Nationwide Inpatient Sample databases were included. Patients with a diagnosis of gynecologic malignancy or concurrent hysterectomy were excluded. Population-level weighted estimates were developed, and perioperative morbidity, mortality, and hospital charges were examined based on surgical approach for each procedure. RESULTS: The cohort included 351,207 women who underwent oophorectomy and 220,893 women who underwent cystectomy, when weighted representing 547,836 and 328,408 patients, respectively, nationwide. A minimally invasive surgical approach was used in 294,190 (89.6%) patients who underwent ovarian cystectomy, and in 478,402 (87.3%) of patients who underwent oophorectomy. Use of minimally invasive surgery for cystectomy increased from 88.7% in 2016 to 91.0% in 2018, and the rate of minimally invasive surgery for oophorectomy increased from 85.8% to 88.7% over the same time period (P<.001 for both). The complication rates for ovarian cystectomy were 2.7% for minimally invasive surgery and 8.8% for laparotomy (P<.001); for oophorectomy the complication rate was 3.1% for minimally invasive surgery and 22.9% for laparotomy (P<.001). CONCLUSION: Minimally invasive surgery is used in the majority of women who are undergoing oophorectomy and ovarian cystectomy for benign indications. Compared with laparotomy, minimally invasive surgery is associated with fewer complications.

[Surgical de-escalation for head and neck cancer surgery]. / Désescalade en chirurgie oncologique cervico-faciale.

Head and neck cancer surgery often has functional and aesthetic consequences. De-escalation surgery is a major concern for surgeons with a constant desire to develop surgical techniques with less invasive approaches and to preserve anatomical structures as much as possible. This was made possible by the appearance of minimally transoral and endonasal surgery as well as by the limitation of the surgical procedure by neoadjuvant treatments or by the limitation of surgical excision without compromising the oncological outcome and patient survival. This evolution continues with the arrival of new technologies such as virtual reality or artificial intelligence.

The Minimally Invasive Posterolateral Transcavernous-Transtentorial Approach. Technical Nuances, Proof of Feasibility, and Surgical Outcomes Throughout a Case Series of Sphenopetroclival Meningiomas.

OBJECTIVE: Sphenopetroclival (SPC) meningiomas are considered among the most complex skull-base neoplasms to approach surgically. We aim to determine whether some SPC meningiomas can be safely and effectively treated using a modified minimally invasive pterional posterolateral transcavernous-transtentorial approach (MIPLATTA). METHODS: Fourteen patients harboring SPC meningiomas were surgically treated through a MIPLATTA. MIPLATTA includes a minipterional craniotomy, anterior extradural clinoidectomy, peeling of the temporal fossa, decompression of cranial nerves (CNs) in the cavernous sinus, and sectioning of the tentorium to reach the upper part of the posterior fossa. RESULTS: Gross total resection was achieved in 11 of 14 patients (78%), whereas near-total resection was accomplished in the other 3 patients (22%), each of whom underwent a further complementary retrosigmoid approach for gross total tumor resection. There were no deaths, and 13 of 14 patients were independent at 6 months follow-up (modified Rankin Scale score ≤2). One patient had pontine infarction after the procedure and experienced moderate disability at follow-up (modified Rankin Scale score 3). All patients had some degree of CN impairment. Of 38 cranial neuropathies, 15 (39%) improved, 20 (53%) remained stable, and 3 (8%) worsened postoperatively. Four new CN deficits were observed postoperatively in 3 patients (fourth CN, 2 patients; third CN, 1; fifth CN, 1). CONCLUSIONS: MIPLATTA is a useful and safe treatment alternative that allows resection of large SPC tumors with dominant invasion of cavernous sinus and middle fossa, preserves hearing and facial motor function, and provides good chances of recovery of visual and oculomotor deficits.

Validation of VR-12 Physical Function in Minimally Invasive Lumbar Discectomy.

BACKGROUND: Although the Veterans RAND 12-item Physical Component Survey (VR-12 PCS) has been broadly used to evaluate patient-reported outcome measures (PROMs) in spine surgery, its feasibility for use in patients undergoing minimally invasive lumbar discectomy (MIS LD) has not been well studied. This study aimed to assess the feasibility of VR-12 PCS for use up to 2 years postoperatively for MIS LD by correlation with PROMs for physical function. METHODS: Patients undergoing primary single-level MIS LD procedures were reviewed retrospectively. Results on the VR-12 PCS, 12-Item Short Form (SF-12) PCS, and Patient-Reported Outcomes Measurement Information System (PROMIS PF) were recorded preoperatively and up to 2 years postoperatively. Improvements in postoperative PROMs were calculated and assessed for significant differences from baseline values. Correlation significance and strength were evaluated between VR-12 PCS and SF-12 PCS or PROMIS PF. Scatterplots were constructed to demonstrate relationships of VR-12 PCS with SF-12 PCS and PROMIS PF at each time point. RESULTS: Our cohort comprised 402 patients. Patients improved significantly from preoperative baseline for all 3 PROMs at all postoperative time points. Both Pearson's correlation and time-independent partial correlation revealed statistically significant strong correlations of VR-12 PCS with SF-12 PCS and PROMIS PF through 2-years. DISCUSSION: Physical function scores for VR-12, SF-12, and PROMIS PF all demonstrated significant improvements following MIS LD. Strongly statistically significant correlations of VR-12 PCS with SF-12 PCS and PROMIS PF from preoperative measures through 2 years demonstrate the feasibility of VR-12 for assessing patient-reported physical function in MIS LD patients.

Patient Satisfaction Following Minimally Invasive and Open Surgeries for Adult Spinal Deformity.

BACKGROUND: Patient satisfaction has become an important variable in assessing outcomes after spine surgery. Although minimally invasive surgery (MIS) techniques have become popular owing to reduced perioperative complications compared with open deformity surgery, whether patient-reported postoperative satisfaction differ between the 2 surgical approaches is unclear. The aim of this study was to characterize postoperative patient-reported outcomes (PRO) in patients who underwent open surgery or MIS for adult spinal deformity (ASD). METHODS: PRO scores were prospectively collected for patients undergoing deformity correction surgery between 2016 and 2018. Inclusion criteria were age >18 years, ASD, and completed PRO surveys. Patient demographic, clinical, and radiographic data and PRO survey responses were analyzed. A post hoc analysis comparing patients who were satisfied with their outcome and those who were unsatisfied was performed. RESULTS: Forty patients who underwent operative management of ASD (19 in the open surgery group and 21 in the MIS group) met the criteria for inclusion in this study. Patients in the MIS group reported higher mental health and self-image scores at 6 months; however, at the 12-month follow-up, both the open surgery and MIS groups reported minimal clinically important differences in back pain, leg pain, and functional status. Patient satisfaction scores did not differ based on surgical approach or intraoperative complications. CONCLUSIONS: PRO after open surgery and after MIS for ASD reflected successful outcomes with significant improvements in PRO survey scores but with subtle differences in the postoperative recovery process. The MIS group reported faster recovery with earlier improvement in self-image and mental health scores, which may stem from correction of smaller deformities. At the 12-month follow-up, postoperative satisfaction was high for the majority of patients in both groups.

The evolution of surgical virtual education and telementoring: One surgeon's journey.

The first era of the global proliferation of surgical advancements involved surgical infection rate and technique breakthroughs by Lister, Halsted, and others. This was propagated by letters, academic papers, and international visits. While success was achieved, it was at a suboptimal pace. In the current era of minimally invasive surgical approaches, these methods are inadequate. This paper chronicles the development and application of virtual learning and telementoring as force multipliers to speed procedural adoption and proliferation.

Patient-reported outcome measures after mitral valve repair: a comparison between minimally invasive and sternotomy.

OBJECTIVES: To compare patient-reported outcome measures of minimally invasive (MI) to sternotomy (ST) mitral valve repair. METHODS: We included all patients undergoing isolated mitral valve surgery via either a right mini-thoracotomy (MI) or ST over a 36-month period. Patients were asked to complete a modified Composite Physical Function questionnaire. Intraoperative and postoperative outcomes, and patient-reported outcome measures were compared between 2 propensity-matched groups (n = 47/group), assessing 3 domains: 'Recovery Time', 'Postoperative Pain' (at day 2 and 1, 3, 6 and 12 weeks) and 'Treatment Satisfaction'. Composite scores for each domain were subsequently constructed and multivariable analysis was used to determine whether surgical approach was associated with domain scores. RESULTS: The response rate was 79%. There was no mortality in either group. In the matched groups, operative times were longer in the MI group (P < 0.001), but postoperative outcomes were similar. Composite scores for Recovery Time [ST 51.7 (31.8-62.1) vs MI 61.7 (43.1-73.9), P = 0.03] and Pain [ST 65.7 (40.1-83.1) vs MI 79.1 (65.5-89.5), P = 0.02] significantly favoured the MI group. Scores in the Treatment Satisfaction domain were high for both surgical approaches [ST 100 (82.5-100) vs MI 100 (95.0-100), P = 0.15]. The strongest independent predictor of both faster recovery parameter estimate 12.0 [95% confidence interval (CI) 5.7-18.3, P < 0.001] and less pain parameter estimate 7.6 (95% CI 0.7-14.5, P = 0.03) was MI surgery. CONCLUSIONS: MI surgery was associated with faster recovery and less pain; treatment satisfaction and safety profiles were similar.

Understanding the Future Prospects of Synergizing Minimally Invasive Transforaminal Lumbar Interbody Fusion Surgery with Ceramics and Regenerative Cellular Therapies.

Transforaminal lumber interbody fusion (TLIF) is the last resort to address the lumber degenerative disorders such as spondylolisthesis, causing lower back pain. The current surgical intervention for these abnormalities includes open TLIF. However, in recent years, minimally invasive TLIF (MIS-TLIF) has gained a high momentum, as it could minimize the risk of infection, blood loss, and post-operative complications pertaining to fusion surgery. Further advancement in visualizing and guiding techniques along with grafting cage and materials are continuously improving the safety and efficacy of MIS-TLIF. These assistive techniques are also playing a crucial role to increase and improve the learning curve of surgeons. However, achieving an appropriate output through TLIF still remains a challenge, which might be synergized through 3D-printing and tissue engineering-based regenerative therapy. Owing to their differentiation potential, biomaterials such as stem/progenitor cells may contribute to restructuring lost or damaged tissues during MIS-TLIF, and this therapeutic efficacy could be further supplemented by platelet-derived biomaterials, leading to improved clinical outcomes. Thus, based on the above-mentioned strategies, we have comprehensively summarized recent developments in MIS-TLIF and its possible combinatorial regenerative therapies for rapid and long-term relief.
