Comparison of Hemodynamic Effect of Propofol and Ketofol during Induction of Anaesthesia in General Surgery Patients

Objective: To determine the comparison of homodynamic effect of propofol and ketofol duringinduction in general surgery patients.Study design: Randomized control trialSetting: Department of Anesthesia, Surgical ICU and Pain management, Civil Hospital Karachi.Duration: Seven months from June 2019 to January 2020.Methods: Patients scheduled for elective general surgery procedures, aged 20 to 60 years, bothmale and female patients were included. Patients were randomly allocated into two groups.Group A received a combination of ketofol while Group B received propofol as the inductionagent. After recording of the base line values of mean arterial pressure patient was induced usingpropofol or ketofol. Mean arterial pressure readings were noted at 30 seconds after druginjection, as well as at 1 minute, 5 minutes, and 10 minutes after intubation, to capture theimmediate hemodynamic effects of the drugs and to observe any potential changes over timefollowing intubation.Results: The average age of the patients was 37.38±13.78 years. Out of 64 patients, 30(46.9%)were male and 34(53.1%) were female. Homodynamic effect was significantly high in thosepatients who received ketofol than those who received propofol (100% vs. 59.4% p=0.0005).The findings observed also with significant differences in hemodynamic effects between the twogroups, even after controlling for age, gender, and ASA classification (p-<0.05).Conclusion: Combination of Ketofol with ketofol was observed to be the betterhemodynamically as compared to Propofol. Additionally, the use of ketofol reduces the cost ofinduction and decreasing the economic burden on the patient.

Temporal and institutional trends in robotic surgery.

Robotic surgery has become increasingly prevalent in general surgery practice. While previous studies have shown the safety and efficacy of robotic assistance in laparoscopic general surgery procedures, few studies have evaluated the temporal and regional trends in implementation. In our retrospective population-based study, we aim to evaluate the national trends in robotic surgery. National Inpatient Database (NIS 2009-2014) was used to identify adults who underwent robotic assisted surgery (ICD 9 codes 17.41 to 17.49). Robotic procedures related to seven abdominal organ systems were compared against the trends of Urology, Gynaecologic, and Orthopedic robotic procedures. Discharge weights were applied to calculate National temporal trends separated by hospital size, teaching status and US geographic region. 894,163 patients received a robotic assisted procedure between 2009 and 2014 with 64% increase in utilization. The largest percent change was witnessed in biliary robotic procedures with 2984% change in utilization, followed by hernia (1376%). Lowest percent change was witnessed in esophageal procedures with 114% increase. Medium sized hospitals had the largest change in robotic utilization (41%), with large institutions seeing 18% decrease. Gastric procedures were the most common robotic procedure performed at small institutions (7917 total cases; 316%). Large institutions saw an overall decrease in gastric (-47%), esophageal (-17%), small and large intestinal (-16%), and hepatic (-7%) robotic procedures. Rural non-teaching hospitals saw the largest increase in robotic surgery (274%). Urban non-teaching hospitals saw a decrease of 29%. While urban teaching institutions saw a 20% and 6% increase in gynecological and urological procedures, an overall decrease was seen in esophageal (-10%), gastric (-12%), intestinal (-11%), hepatic (-17%), biliary (-10%), pancreatic (-11%) and hernia procedures (-14%). Biliary procedures saw the largest increase in rural institutions (740 cases; 392%), followed by hernia (144% increase). South region of the nation had the largest increase in robotic procedures (23%). No change was seen in the use of robotic surgery in the northeast region with the midwest and west seeing an overall decrease (-4% and -22%, respectively). Our study highlights the increase in use of robotics for both general and specialty surgery, with an increase in utilization over time. Increased incidence of robotic surgery in smaller, rural institutions with overall decrease in larger, urban teaching hospitals suggests increasing comfort in robotic surgery in the community setting. Further studies are necessary to evaluate the factors associated with increased utilization in smaller institutions.

Does delayed operation increase morbidity and mortality? An analysis of emergency general surgery procedures.

Early operation is assumed to improve outcomes after emergency general surgery (EGS) procedures; however, few data exist to inform this opinion. We aimed to (1) characterize time-to-operation patterns among EGS procedures and (2) test the association between timing and patient outcomes. We hypothesize that patients receiving later operations are at greater risk for mortality and morbidity. We performed a retrospective cohort study of the American College of Surgeons National Surgical Quality Improvement Program data for adults aged 18 to 89 years who underwent nonelective intra-abdominal operations (appendectomy, cholecystectomy, small bowel resection, lysis of adhesions, and colectomy) from 2015 to 2020. The primary outcome was 30-day postoperative mortality. Secondary outcomes were serious morbidity and all morbidity. Admission-to-operation timing was calculated and classified as early (≤48 hours) or late (>48 hours). A multivariable logistic regression model adjusted risk estimates for age, comorbidities, frailty (Modified Frailty Index, 5-item score), and other confounders. Of 269,959 patients (mean age, 47.0 years; 48.0% male, 61.6% White), 88.7% underwent early operation, ranging from 70.36% (lysis of adhesions) to 98.67% (appendectomy). Unadjusted 30-day mortality was higher for late versus early operation (6.73% vs. 1.96%; p < 0.0001). After risk adjustment, late operation significantly increased risk for 30-day mortality (odds ratio [OR], 1.545; 95% confidence interval [CI], 1.451-1.644), serious morbidity (OR, 1.464; 95% CI, 1.416-1.514), and all morbidity (OR, 1.468; 95% CI, 1.417-1.520). This mortality risk persisted for all EGS procedures; risk of serious and any morbidity persisted for all procedures except cholecystectomy. Late operation significantly increased risk for 30-day mortality, serious morbidity, and all morbidity across a variety of EGS procedures. We believe that these findings will inform decisions regarding timing of EGS operations and allocation of surgical resources. Therapeutic/Care Management; Level III.

Opportunistic Salpingectomy at the Time of General Surgery Procedures: A Systematic Review and Narrative Synthesis of Current Knowledge

Opportunistic salpingectomy (OS) for the primary prevention of ovarian cancer is performed by gynecologists. Advocates have suggested expanding its use to other surgical specialties. General surgeons are the other group to routinely perform intraperitoneal operations in women and could play a role in ovarian cancer prevention. Herein, we review the current evidence and perioperative factors requiring consideration prior to OS implementation in select general surgery cases. A systematic search was conducted for English-language studies evaluating OS during general surgery. The primary outcomes of this study were the feasibility and safety of OS during general surgery procedures. Secondary outcomes included pre-operative considerations (patient selection and the consent process), operative factors (technique and surgical specialty involvement), and post-operative factors (follow-up and management of operative complications). We evaluated 3977 studies, with 9 meeting the eligibility criteria. Few studies exist but preliminary evidence suggests relative safety, with no complication attributable to OS among 140 patients. Feasibility was reported in one study, which showed the capacity to perform OS in 98 out of 105 cholecystectomies (93.3%), while another study reported quick visualization of the fallopian tubes in &gt;80% of cases. All patients in the included studies were undergoing elective procedures, including cholecystectomy, interval appendectomy, colorectal resection, bariatric surgery, and laparoscopic hernia repair. Studies only included patients ≥ 45 years old, and the mean age ranged from 49 to 67.5 years. Gynecologists were frequently involved during the consent and surgical procedures. OS represents a potential intervention to reduce the risk of ovarian cancer. Ongoing studies evaluating the general surgeon’s understanding; the consent process; the feasibility, operative outcomes, and risks of OS; and surgeon training are required prior to consideration.

Proposal of set-up standardization for general surgery procedures with the CMR Versius system, a new robotic platform: our initial experience.

The article describes our initial experience using CMR Versius platform for several procedures in general surgery. Between September 2022 and April 2023, seventy patients underwent robotic surgery in a multi-robotic referral center (San Paolo University Hospital, Milan, Italy). Three surgeons with only laparoscopic experience performed 24 cholecystectomies, 13 inguinal hernia repairs, 9 ventral hernia repairs, 7 right hemicolectomies, 11 left hemicolectomies, 1 sigmoidectomy, 1 ileocecal resection, 1 ventral rectopexy, 1 Nissen fundoplication, 1 total splenectomy, and 1 exploration with multiple biopsies. All surgeries were full-robotic, with only one conversion to laparoscopy. The short length of stay and low rate of severe morbidity are promising findings. Although operative time was lengthened, clinical outcomes were not affected. Our experience demonstrates that the adoption of Versius system is safe and feasible in general surgery. The standardization of port placement and BSU set-up can certainly reduce the operative time.

Evaluation of operating room inefficiencies and their impact on operating room duration using a surgical app

BackgroundEfficient utilization of the operating room (OR) is essential. Inefficiencies are thought to cause preventable delays. Our goal was to identify OR incidents causing delays and estimate their impact on the duration of various general surgery procedures. MaterialsThree trained observers prospectively collected intraoperative data using the ExplORer Surgical app, a tool that helped capture incidents causing delays. The impact of each incident on case duration was assessed using multivariable analysis. Results151 general surgery procedures were observed. The mean number of incidents was 2.7 per each case that averaged 109min. On average, each incident caused a 2.8 ​min delay (p ​< ​0.001), however, some incidents were associated with longer delays. The procedural step of each procedure most susceptible to incidents was also defined. ConclusionThe identification of the type of incidents and the procedural step during which they occur may allow targeted interventions to optimize OR efficiency and decrease operative time.

Quality of life among older patients after elective ventral hernia repair: A retrospective review

BackgroundVentral hernia repair is a common elective general surgery procedure among older patients, a population at greater risk of complications. Prior research has demonstrated improved quality of life in this population despite increased risk of complications. This study sought to assess the relationship between post–ventral hernia repair quality of life and patient frailty. We hypothesized that frail patients would report smaller gains in quality of life compared to the non-frail group. MethodsThe Abdominal Core Health Quality Collaborative was used to identify a cohort of patients 65 years of age or older undergoing elective ventral hernia repair from 2018 to 2022. Patients were categorized based on their modified frailty index scores as not frail/prefrail, frail, and severely frail. Quality of life was assessed using a patient-reported 12-item scale preoperatively, 30 days, 6 months, and 1 year postoperatively. ResultsA total of 3,479 patients were included: 30.93% non-frail, 47.17% frail, and 21.90% severely frail. Severely frail patients had lower quality of life scores at baseline (P = .001) but reported higher quality of life at both 30 days (1.24 points higher, 95% confidence interval (–1.51, 2.52), P = .010) and 6 months (0.92 points higher, 95% confidence interval (–2.29, 4.13), P = .005). Severely frail patients had higher rates of surgical site complications (P < .001) but no difference in 30-day readmissions. ConclusionOur results found that frail patients reported the greatest increase in quality of life 1 year from baseline, showing that they, when selected appropriately, can gain equal benefits and have similar surgical outcomes as their non-frail counterparts.

Evaluating the scope of rural general surgery in British Columbia.

Rural general surgeons perform many procedures outside the conventional scope of the specialty. Unique to British Columbia, the Rural Practice Subsidiary Agreement (RSA) formally defines rurality in the province. Our goal is to understand the scope of practice for BC's rural general surgeons and whether it has been affected over time by changing privileging guidelines. Medical Services Plan (MSP) data were collected from 2011 to 2021 for procedures billed by general surgeons in communities defined by the RSA as rural. We categorized codes from the MSP based on surgical specialty. For each community, we calculated the totals for these categories considering what other surgical specialties were present as well as changes over time. From 2011 to 2021, 222 905 procedures were performed in 23 rural communities in BC. Colonoscopies were the most frequently performed procedure (n = 80 114, 35.9%), followed by colorectal (n = 23 891, 10.7%) and hernia procedures (n = 20 911, 9.4%). The most common unconventional procedures were plastic surgeries (n = 8077, 3.6%). Classification within the RSA did not significantly influence the percentage of unconventional general surgery procedures performed (p = 0.4). When another surgical specialty was present, there was often a decrease in the number of that specialty's procedures performed by general surgeons. Over the past decade, rural general surgeons performed fewer unconventional general surgery procedures (p < 0.001). General surgeons working in rural communities perform a variety of procedures based on resources, community need, and access to other specialists. Over the last decade, this appears to have been influenced by new privileging guidelines. Understanding the scope of rural general surgery can inform training opportunities and, as there is a migration away from rural surgeons performing as many unconventional procedures, can elucidate the implications on patients and communities.

The overlooked factor: The impact of disability on postoperative complications after emergency general surgery procedures

BackgroundDespite more than 61 million people in the United States living with a disability, studies on the impact of disability on health care disparities in surgical patients remain limited. Therefore, we aimed to understand the impact of disability on postoperative outcomes. MethodsWe performed a retrospective cohort study using the Nationwide Readmission Database (2019). We compared patients ≥18 years undergoing emergency general surgery procedures with a disability condition with those without a disability. In accordance with the Centers for Disease Control and Prevention, disability was defined as severe hearing, visual, intellectual, or motor impairment/caregiver dependency. The primary outcome was 30-day readmission rates. Secondary outcomes included hospital length of stay and 30-day complications and mortality. Patients were 1:1 propensity-matched using patient, procedure, and hospital characteristics. ResultsAmong our population of 378,733 patients, 5,877 (1.6%) patients had at least 1 disability condition. A higher proportion of patients with a disability had low household income, $1 to $45,999, and an Elixhauser Comorbidity score ≥3. Among 5,768 matched pairs, patients with a disability had a significantly higher incidence of 30-day readmission (17.2% vs 12.7%; P < .001), infectious complications (29.8% vs 19.5%; P < .001), and a longer length of stay (8 vs 6 days; P < .001). Motor impairment, the most common disability, was associated with the greatest increase in patient readmission, morbidity, and length of stay. ConclusionSevere intellectual, hearing, visual, or motor impairments were associated with higher readmission, morbidity, and longer length of stay. Further research is needed to understand the mechanisms responsible for these disparities and to develop interventions to ameliorate them.

Changes in social care after major emergency general surgery procedures

IntroductionEmergency General Surgery (EGS) is a major part of the provision of healthcare and patients undergoing EGS are at elevated risk of morbidity and mortality. The aim of this study is to determine factors contributing to patients losing their independence and being discharged to residential and nursing homes having previously lived in their own residences. MethodsOur local data uploaded to the National Emergency Laparotomy Audit (NELA) database (2014-2022) was analysed. This national database encompasses all major emergency general surgery cases undertaken in the United Kingdom. The variables considered were patient demographics, ASA score, admission and discharge dates, presenting pathology, operation type, and discharge destination. Comparative analyses segmented patients based on post-discharge EGS destinations. Multivariable logistic regression identified factors linked to residential/nursing home placement post-discharge. Significance was set at p<0.05. ResultsData from all patients in the NELA database (n=1,611) was analysed. Nearly one in ten patients over the age of 70 never returned home. Patients requiring additional support were on average 8.6 years older (p=0.008). Over the age of 80 years, the need for extra social support increased substantially with each increasing year in age and those over the age of 85 years old were more than twice as likely to require extra support than 80-year-olds (p<0.001). Patients who died were 11.4 years older compared to those discharged without additional support (p<0.001). ConclusionA significant proportion of patients, particularly the elderly, do not return to their usual place of residence and require a higher level of care post-emergency surgery. These important social factors need to be considered before operating as they may have significant quality of life and economic implications.

A modified Hospital Frailty Risk Score for patients with cirrhosis undergoing abdominal operations.

Existing tools for perioperative risk stratification in patients with cirrhosis do not incorporate measures of comorbidity. The Hospital Frailty Risk Score (HFRS) is a widely used measure of comorbidity burden in administrative dataset analyses. However, it is not specific to patients with cirrhosis, and application of this index is limited by its complexity. Adult patients with cirrhosis who underwent nontransplant abdominal operations were identified from the National Inpatient Sample, 2016-2018. Adjusted associations between HFRS and in-hospital mortality and length of stay were computed with logistic and Poisson regression. Lasso regularization was used to identify the components of the HFRS most predictive of mortality and develop a simplified index, the cirrhosis-HFRS. Of 10,714 patients with cirrhosis, the majority were male, the median age was 62 years, and 32% of operations were performed electively. HFRS was associated with an increased risk of both in-hospital mortality (OR=6.42; 95% CI: 4.93, 8.36) and length of stay (incidence rate ratio [IRR]=1.79; 95% CI: 1.72, 1.88), with adjustment. Using lasso, we found that a subset of 12 of the 109 ICD-10 codes within the HFRS resulted in superior prediction of mortality in this patient population (AUC = 0.89 vs. 0.79, p < 0.001). While the 109-component HFRS was associated with adverse surgical outcomes, 12 components accounted for much of the association between the HFRS and mortality. We developed the cirrhosis-HFRS, a tool that demonstrates superior predictive accuracy for in-hospital mortality and more precisely reflects the specific comorbidity pattern of hospitalized patients with cirrhosis undergoing general surgery procedures.

Outcomes and quality of life of frail patients following elective ventral hernia repair: Retrospective review of a national hernia collaborative

BackgroundVentral hernia repair (VHR) is one of the most common general surgery procedures among older adults but is often deferred due to a higher risk of complications. This study compares postoperative quality of life (QOL) and complications between frail and non-frail patients undergoing elective VHR. We hypothesized that frail patients would have higher complication rates and smaller gains in quality of life compared to non-frail patients. Study designPatients 65 years of age and older, undergoing elective VHR between 2018 and 2022 were selected from the ACHQC (Abdominal Core Health Quality Collaborative) and grouped based on frailty scores obtained using the Modified Frailty Index (mFI-5). Logistic regression adjusting for hernia characteristics (size, recurrent, parastomal, incisional) were performed for 30-day outcomes including surgical site infections (SSI), surgical site occurrences (SSO), surgical site infections/occurrences requiring procedural intervention (SSOPI), and readmission. Multivariable analyses controlling for patient and procedure characteristics were performed comparing QOL scores (HerQLes scale, 0–100) at baseline, 30 days, 6 months and 1 year postoperatively. ResultsA total of 4888 patients were included, 29.17% non-frail, 47.87% frail, and 22.95% severely frail. On adjusted analysis, severely frail patients had higher odds of SSO (most commonly seroma formation) but no evidence of a difference in SSI, SSOPI, readmission or mortality. Severely frail patients had lower median QOL scores at baseline (48.3/100, IQR 26.1–71.7, p ​= ​0.001) but reported higher QOL scores at both 30-days (68.3/100, IQR 41.7–88.3, p ​= ​0.01) and 6-months (86.7/100, IQR 65.0–93.3, p ​= ​0.005). ConclusionSeverely frail patients reported similar increases in QOL and similar complications to their not frail counterparts. Our results demonstrate that appropriately selected older patients, even those who are severely frail, may benefit from elective VHR in the appropriate clinical circumstance.

Patient reported outcomes of emergency general surgery procedures

BackgroundEmergency general surgery (EGS) involves care of a patient's often previously unknown disease in the setting of an unplanned interaction with the healthcare system. This leads to challenges collecting and interpreting patient reported outcome measures (PROMs). MethodsWe performed a qualitative and mixed methods study using semi-structured interviews during the index hospitalization and at 6–12 months to capture peri-operative patient experiences. We compared interview findings to clinical characteristics. ResultsAmong 30 patients, two-thirds reported feeling no choice but to pursue emergency surgery with many reporting exclusion from decision-making. Females reported these themes more commonly. Patients with minor complications less frequently reported trust in their team and discussed communication issues and delays in care (all p ​< ​0.05). Patients with major complications more frequently reported confidence in their team and gratefulness, but also communication limitations (all p ​< ​0.05). Patients not admitted to the ICU more frequently discussed good communication and expeditious treatment. ConclusionsPROMs developed for EGS patients should consider patient outcomes and reflections that they felt excluded from decision-making. Severity of complications may also differentially impact PROMs.

Comparing resident operative volumes for routine general surgery cases at academic, urban community, and rural training sites.

Surgical training traditionally took place at academic centres, but changed to incorporate community and rural hospitals. As little data exist comparing resident case volumes between these locations, the objective of this study was to determine variations in these volumes for routine general surgery procedures. We analyzed senior resident case logs from 2009 to 2019 from a general surgery residency program. We classified training centres as academic, community, and rural. Cases included appendectomy, cholecystectomy, hernia repair, bowel resection, adhesiolysis, and stoma formation or reversal. We matched procedures to blocks based on date of case and compared groups using a Poisson mixed-methods model and 95% confidence intervals (CIs). We included 85 residents and 28 532 cases. Postgraduate year (PGY) 3 residents at academic sites performed 10.9 (95% CI 10.1-11.6) cases per block, which was fewer than 14.7 (95% CI 13.6-15.9) at community and 15.3 (95% CI 14.2-16.5) at rural sites. Fourth-year residents (PGY4) showed a greater difference, with academic residents performing 8.7 (95% CI 8.0-9.3) cases per block compared with 23.7 (95% CI 22.1-25.4) in the community and 25.6 (95% CI 23.6-27.9) at rural sites. This difference continued in PGY5, with academic residents performing 8.3 (95% CI 7.3-9.3) cases per block, compared with 18.9 (95% CI 16.8-21.0) in the community and 14.5 (95% CI 7.0-21.9) at rural sites. Senior residents performed fewer routine cases at academic sites than in community and rural centres. Programs can use these data to optimize scheduling for struggling residents who require exposure to routine cases, and help residents complete the requirements of a Competence by Design curriculum.

Assessing the Ambulatory Surgery Center Volume-Outcome Association

In surgical patients, it is well known that higher hospital procedure volume is associated with better outcomes. To our knowledge, this volume-outcome association has not been studied in ambulatory surgery centers (ASCs) in the US. To determine if low-volume ASCs have a higher rate of revisits after surgery, particularly among patients with multimorbidity. This matched case-control study used Medicare claims data and analyzed surgeries performed during 2018 and 2019 at ASCs. The study examined 2328 ASCs performing common ambulatory procedures and analyzed 4751 patients with a revisit within 7 days of surgery (defined to be either 1 of 4735 revisits or 1 of 16 deaths without a revisit). These cases were each closely matched to 5 control patients without revisits (23 755 controls). Data were analyzed from January 1, 2018, through December 31, 2019. Seven-day revisit in patients (cases) compared with the matched patients without the outcome (controls) in ASCs with low volume (less than 50 procedures over 2 years) vs higher volume (50 or more procedures). Patients at a low-volume ASC had a higher odds of a 7-day revisit vs patients who had their surgery at a higher-volume ASC (odds ratio [OR], 1.21; 95% CI, 1.09-1.36; P = .001). The odds of revisit for patients with multimorbidity were higher at low-volume ASCs when compared with higher-volume ASCs (OR, 1.57; 95% CI, 1.27-1.94; P < .001). Among patients with multimorbidity in low-volume ASCs, for those who underwent orthopedic procedures, the odds of revisit were 84% higher (OR, 1.84; 95% CI, 1.36-2.50; P < .001) vs higher-volume centers, and for those who underwent general surgery or other procedures, the odds of revisit were 36% higher (OR, 1.36; 95% CI, 1.01-1.83; P = .05) vs a higher-volume center. The findings were not statistically significant for patients without multimorbidity. In this observational study, the surgical volume of an ASC was an important indicator of patient outcomes. Older patients with multimorbidity should discuss with their surgeon the optimal location of their care.

Implementation of Guidelines Limiting Postoperative Opioid Prescribing at a Children's Hospital.

Variability in opioid-prescribing practices after common pediatric surgical procedures at our institution prompted the development of opioid-prescribing guidelines that provided suggested dose limitations for narcotics. The aims of this study were to improve opioid prescription practices through implementation of the developed guidelines and to assess compliance and identify barriers preventing guideline utilization. We conducted a single-center cohort study of all children who underwent the most common outpatient general surgery procedures at our institution from August 1, 2018, to February 1, 2020. We created guidelines designed to limit opioid prescription doses based on data obtained from standardized postoperative telephone interviews. Three 6-month periods were evaluated: before guideline implementation, after guideline initiation, and after addressing barriers to guideline compliance. Targeted interventions to increase compliance included modification of electronic medical record defaults and provider educations. Differences in opioid weight-based doses prescribed, filled, and taken, as well as protocol adherence between the 3 timeframes were evaluated. A total of 1033 children underwent an outpatient procedure during the 1.5-year time frame. Phone call response rate was 72.22%. There was a significant sustained decrease in opioid doses prescribed ( P < 0.0001), prescriptions filled ( P = 0.009), and opioid doses taken ( P = 0.001) after implementation, without subsequent increase in reported pain on postoperative phone call ( P = 0.96). Protocol compliance significantly improved (62.39% versus 83.98%, P < 0.0001) after obstacles were addressed. Implementation of a protocol limiting opioid prescribing after frequently performed pediatric general surgery procedures reduced opioids prescribed and taken postoperatively. Interventions that addressed barriers to application led to increased protocol compliance and sustained decreases in opioids prescribed and taken without a deleterious effect on pain control.

Single-port robotic subcostal major pulmonary resection using the single-port robotic system.

The da Vinci single-port system (SPS) (Intuitive Surgical, Sunnyvale, CA, USA) was designed for single-port (SP) surgery. Although we have reported our clinical outcomes using the SPS for a simple procedure in general thoracic surgery, major pulmonary resection had been performed only in cadaveric experiments to date. This study evaluated the feasibility of SP subcostal robotic major pulmonary resection using the SPS. Here, we present our initial clinical experience of SP subcostal robotic major pulmonary resection at our institution. Twenty-five patients with lung cancer underwent SP major subcostal pulmonary resection using the SPS between March and November 2022. Patient characteristics, intraoperative and perioperative outcomes were assessed. Questionnaires were used to evaluate patient satisfaction with the cosmetic results and quality of life through face-to-face or telephone interviews on postoperative day 30. All patients underwent major pulmonary resection with complete radical resection (R0). Nineteen patients underwent lobectomy, whereas six patients underwent segmentectomy. The mean docking time and total operative time were 4.16±1.19min (range, 2.3-7.8min) and 197.6±55.33min (range, 130-313min), respectively. No patients underwent conversion to open thoracotomy. One patient required an additional assistant port due to severe pleural adhesions. SP subcostal robotic major pulmonary resection using the SPS is feasible and safe. With the continuous development of robotic technology and surgical techniques, we believe that more complex general thoracic surgeries will be performed in the future using SPS.

Venture Capital's Role in Advancing Plastic Surgery.

Abstract Plastic surgery sector has experienced significant growth, driven by an aging population's demand for minimally invasive procedures and technological innovation. Despite this, the role of venture capital (VC) in driving innovation within this sector remains underexplored. This study aimed to analyze the trends in VC investments in plastic surgery over the last 20 years, providing insights into the financial landscape of the sector. A retrospective cross-sectional analysis was conducted on VC investments in plastic and aesthetic surgery companies worldwide from January 1, 2003 to December 31, 2023, utilizing PitchBook (Seattle, WA). Companies were categorized into therapeutic and thematic areas, with investment trends analyzed by deal and company values, average investment size, and total capital invested. The study found 543 VC firms made 402 investments in 163 companies, totaling $1.98 billion, increasing by 15,143% over the study period, and focused on general plastic surgery and facial cosmetic procedures. Significant investments were also made in surgical software (25.3%), biotechnology and drug discovery (22.8%), and clinic and outpatient services (20.3%). Geographically, most investments were made in companies registered in Asia (45%) and North America (33.2%). VC investments have contributed to the growth and innovation in the plastic surgery sector, particularly in minimally invasive devices. The focus on general and facial cosmetic surgery aligns with market demand trends for aesthetic procedures. These findings underscore the importance of VC in shaping the future of plastic surgery and suggest the potential for strategic investments to further drive innovation.
