Robotic operations in urgent general surgery: a systematic review

Minimally invasive versus open surgery for colonic diverticular disease: a nationwide analysis of German hospital data

BACKGROUND

This study aims to evaluate the current rates and outcomes of minimally invasive versus open surgery for colonic diverticular disease in Germany, using a nationwide dataset.

METHODS

We analyzed data from 36 hospitals, encompassing approximately 1.25 million hospitalizations from 1 January 2019 to 31 December 2023. Patients aged 18 years and older with colonic diverticular disease (International Classification of Diseases, Tenth Revision (ICD-10): K57.2 and K57.3) who underwent surgical treatment were included. Surgeries were classified as open or minimally invasive (laparoscopic or robotic). Outcomes such as in-hospital mortality, complications, and length of stay were assessed using multivariable logistic and linear regression models.

RESULTS

Out of 1670 patients who underwent surgery for colonic diverticular disease, 63.2% had perforation and abscess. The rate of minimally invasive surgery increased from 34.6% in 2019 to 52.9% in 2023 for complicated cases and from 67.8% to 86.2% for uncomplicated cases. Open surgery was associated with higher in-hospital mortality (odds ratio (OR): 7.41; 95% CI: 2.86-19.21) and complications compared with minimally invasive surgery. The length of hospital stay was significantly longer for open surgery patients, with an increase of 4.6 days for those with perforation and abscess and 5.0 days for those without.

CONCLUSIONS

Minimally invasive surgery for colonic diverticular disease is increasingly preferred in Germany, especially for uncomplicated cases. However, open surgery remains common for complicated cases, but is associated with higher mortality, more complications, and longer hospital stays.

Rise of the robots: implementing robotic surgery into the acute care surgery practice

OBJECTIVES

Acute Care Surgery (ACS) admissions and procedures are substantially increasing. ACS disproportionally accounts for a majority of morbidity and mortality among surgical patients. Minimally invasive techniques are associated with improved outcomes and shorter hospital length of stay within the ACS population. While laparoscopy is widespread, ACS surgeons have been slower to adopt the use of robotics. We aimed to evaluate the feasibility of incorporating robotic surgery within ACS practice.

METHODS

Robotic General Surgery operations performed by 8 Acute Care Surgeons from 5 local facilities within a large integrated healthcare system were queried over a 15 month period. Patients who underwent emergent, urgent, sub-acute, and elective robotic operations by ACS staff were identified. Demographics collected included age, gender, BMI, and ASA score. Outcomes recorded included procedure classification, total supply and implant charges (TSI), conversion to open, hospital length of stay (LOS), 30 day readmission, and 30 day mortality.

RESULTS

Of 200 operations, the most common were Cholecystectomy (43.5%), Inguinal hernia repair (26.0%), Ventral hernia repair (18.0%), Appendectomy (5.0%), and Sigmoid Colectomy (3.5%). The median (± std dev) age was 48 ± 16.66 years and BMI was 29.9 ± 8.79 kg/m2. 46% of cases were sub-acute (n = 92), 33.5% were elective (n = 67), 14% were emergent (n = 28), and 6.5% were urgent (n = 13). Most patients were ASA 2 (107, 46.1%) or ASA 3 (71, 45.9%). The median (IQR) TSI and LOS were $1,770 (889.50) USD and 0.1 (0.9) days. Forty-one inpatient procedures were performed. Median LOS was 3 days and expected LOS was 3.1 days (O:E = 0.96). Five patients were readmitted within 30 days, and there were no deaths within 30 days.

CONCLUSION

Robotic techniques may be safely implemented by ACS surgeons, potentially benefitting both patient and surgeon. LOS was similar between laparoscopic and robotic cases and only two cases required conversion to an open procedure. Next steps include a multi-center prospective trial comparing robotic to laparoscopic cases.

Robotic-Assisted Versus Laparoscopic Approach for Treatment of Acute Cholecystitis in Children

Introduction: Laparoscopic cholecystectomy (Lap-C) is the standard of care for patients requiring cholecystectomy in the acute setting. Although robotic-assisted cholecystectomy (RA-C) performance has increased, utilization in the acute setting has not been widely reported. We describe the feasibility of RA-C for pediatric patients undergoing acute inpatient cholecystectomy. Methods: A single institutional retrospective review of patients receiving RA-C while admitted for acute cholecystitis and/or choledocholithiasis (June 2017-June 2022) was compared with a matched cohort who underwent traditional multiport Lap-C (June 2021-June 2022). Demographic, perioperative, and postoperative data were analyzed. Results: Fifty patients were included: 25 each in the RA-C and Lap-C groups. Fifty-four percent were female; 66% were non-Hispanic white. Median age (15.7 years [interquartile range, IQR 14.7, 17.3] versus 15.3 years [IQR 14.5, 16.9], P = .91) and preoperative weight (92.6 kg [IQR 60, 105.9] versus 72.3 kg [IQR 61.6, 85.6], P = .15) were similar between the RA-C and Lap-C groups, respectively. No differences were observed in median operating time (89 minutes [IQR 76, 103] versus 88 minutes [IQR 77, 137], P = .70), postoperative length of stay (22.5 hours [21.4, 24.9] versus 20.6 hours [18.0, 25.1], P = .06), or 30-day complications (12% versus 16%, P = .69). Although opioid utilization (.23 milliequivalents/kilogram [MME/kg] [IQR .03, .30] versus .03 MME/kg [0, .09], P = .02) was higher in the RA-C cohort overall, no differences were detected during an analysis of the most recent 2 years (P = .96). Conclusion: RA-C in the acute setting can be performed safely in the pediatric population with comparable procedural times as well as perioperative and 30-day outcomes.

Severe Abdominal Complications in Lung Transplant Recipients

OBJECTIVES

Lung transplant is a complex procedure with potential for substantial postoperative complications, including abdominal issues. Although previous studies have suggested that preexisting gastrointestinal conditions may be associated with a high risk of posttransplant complications, the evidence remains inconsistent. We aimed to explore the incidence rates, risk factors, and outcomes of abdominal complications within the first year following lung transplant.

MATERIALS AND METHODS

We conducted a retrospective cohort study at the University Hospital Zurich of 68 lung transplant recipients who experienced abdominal complications within 1 year after transplant. Data were collected from medical records on baseline demographic and clinical characteristics, including pretransplant gastrointestinal and hepatobiliary diseases. We used descriptive statistics (Fisher exact test, chi-square test, and Cramer V test) to assess outcome details, such as the timing and type of abdominal complications, surgical interventions, and associations with pretransplant conditions.

RESULTS

Abdominal complications occurred at a mean of 43 days posttransplant, with bowel ischemia and perforation as the most common reasons for posttransplant surgical intervention. Symptoms leading to surgery included nausea and abdominal pain, and 1 of 8 patients with abdominal surgery (12.5%) died after surgery. Notably, no significant associations were found between pretransplant factors (ie, gastrointestinal disease, hepatobiliary disease, body mass index >24, smoking status, peripheral vascular disease, and diabetes) and the occurrence of posttransplant abdominal surgery. Effect size analyses indicated very weak associations, suggesting that these pretransplant conditions are not strong predictors of postoperative abdominal complications.

CONCLUSIONS

Our results showed that preexisting gastrointestinal and hepatobiliary conditions, along with other common pretransplant factors, were not significant predictors of abdominal complications following lung transplant. Future studies should focus on intraoperative and immediate postoperative factors and should explore the role of minimally invasive surgical techniques and potential benefits of earlier or more comprehensive pretransplant screening.

Robotic availability, not payor status, determines access to robotic emergency general surgery hernia repair in California and Florida

BACKGROUND

Previous studies have demonstrated that access to robotic surgery is influenced by socioeconomic factors, including insurance status. The 2010 Affordable Care Act established an avenue for states to expand Medicaid coverage, which has increased access to surgical care for many conditions. We hypothesized that socioeconomic disparities in access to robotic repair of non-elective emergency general surgery (EGS) hernias are less prevalent in California, a Medicaid expansion state, compared to Florida, which has not adopted Medicaid expansion.

METHODS

The 2021 California and Florida State Inpatient Databases were used to identify all EGS admissions with an ICD-10 procedure code for ventral or inguinal hernia repair. Elective procedures and those with concurrent unrelated abdominal procedures were excluded. Patient demographics, comorbidity burden, payor status, and income quartile were abstracted. Aggregation of hospital data identified high-volume trauma, robotic, and EGS centers.

RESULTS

There were 15,683 EGS hernia procedures of which 11% underwent robotic repair: 14% in Florida and 8% in California. On multivariable logistic regression, older age, male sex, lower income, and Medicare insurance were associated with reduced odds of robotic hernia repair in California, but not in Florida, despite an uninsured rate of 10%. The greatest predictor of robotic surgery in both states was treatment at a robotic surgery center. Overall, accounting for patient- and hospital-level factors, hernia surgeries in Florida were more likely to involve robotics (OR 1.61, CI 1.42-1.81, p < 0.001) compared to California.

CONCLUSION

There were fewer disparities in access to EGS robotic hernia repairs in Florida than in California. This suggests that robotic surgery access for EGS hernia repairs is primarily determined by institutional adoption of robotic surgery, not income or payor status. Compared to California, Florida appears to have greater market penetration of robotic surgery, which has increased access to robotic EGS for all patients.

The Great Debate: Robotic vs Traditional Surgical Approach in the Acute Care Setting

Robotic surgery was first introduced in the 1980s as a system to aid patients in the battlefield. Since then, robotic surgery has become an important minimally invasive tool and plays an important role in elective surgery among various surgical specialties. However, the role for robotic surgery in the emergent setting is not well established or studied. Robotic surgery has been shown to be advantageous to both patients and operating surgeons. Though limited, studies have found robotic surgery in the acute setting to be safe for patients. These studies found robotic surgery to have improved perioperative outcomes when compared to an open or laparoscopic approach. Additionally, the robotic platform is thought to be an effective tool to prevent conversion to open procedures in emergent settings. Although some studies demonstrate advantages to robotic acute surgery, others have shown increased complications with robotic acute surgery or no distinct advantage when comparing robotic to laparoscopic surgery. Additionally, some of the published papers supporting the use of robotic surgery in the emergent setting may have a degree of bias favoring the robotic platform. Robotic surgery is a mainstay in minimally invasive elective surgery and gaining popularity among patients and surgeons. There are pros and cons to the adaptation of the robotic platform in the acute care setting. Additional large population studies are indicated to determine the true role of the robotic platform in the emergent setting.

Incorporating Robotic Cholecystectomy in an Acute Care Surgery Practice Model is Feasible

INTRODUCTION

The role of robotic surgery in the nonelective setting remains poorly defined. Accessibility, patient acuity, and high turn-over may limit its applicability and utilization. The goal is to characterize the role of robotic cholecystectomy (CCY) in a busy acute care surgery (ACS) practice at a quaternary medical center, and compare surgical outcomes and resource utilization between robotic and laparoscopic CCY.

METHODS

Adult patients who underwent robotic (Da Vinci Xi) or laparoscopic CCY between 01/2021-12/2022 by an ACS attending within 1 week of admission were included. Primary outcomes included time from admission to surgery, off hour (weekend and 6p-6a) cases, operation time, and hospital costs, to reflect "feasibility" of robotic compared to laparoscopic CCY. Secondary outcomes encompassed surgery-related outcomes and complications.

RESULTS

The proportion of robotic CCY increased from 5% to 32% within 2 years. In total 361 laparoscopic and 89 robotic CCY were performed. Demographics and gallbladder disease severity were similar. Feasibility measures-operation time, case start time, time from admission to surgery, proportion of off-hour cases, and cost-were comparable between robotic and laparoscopic CCY. There were no differences in surgical complications, common bile duct injury, readmission, or mortality. Conversion to open surgery occurred more often in laparoscopic cases (5% vs 0%, P = .02, OR = 1.05).

DISCUSSION

Robotic CCY is associated with fewer open conversions and otherwise similar outcomes compared to laparoscopic CCY in the non-elective setting. Incorporation of robotic CCY in a busy ACS practice model is feasible with available resources.

Is There a Place for Robotic Inguinal Hernia Repair in the Realm of Laparoscopic and Open Inguinal Hernia Repair? A Narrative Review

INTRODUCTION

Robotic hernia repair is gaining popularity among general surgeons and has potential benefits; however, there are also several issues, of which the one related to increased cost compared to other procedures is the most important one. Integrating a robotic platform in the hernia territory is a difficult task, and this review attempts to analyze the various implications of using robotic assistance in inguinal hernias. From a hernia surgeon's perspective, each new addition to hernia procedures is important; therefore, we encompass the advantages and drawbacks of this technology. The final point is obviously improving hernia surgery and quality of life in our patients.

Emergency robotic surgery: the experience of a single center and review of the literature

BACKGROUNDS

Laparoscopic surgery is widely used in abdominal emergency surgery (AES), and the possibility of extending this approach to the more recent robotic surgery (RS) arouses great interest. The slow diffusion of robotic technology mainly due to high costs and the longer RS operative time when compared to laparoscopy may represent disincentives, especially in AES. This study aims to report our experience in the use of RS in AES assessing its safety and feasibility, with particular focus on intra- and post-operative complications, conversion rate, and surgical learning curve. Our data were also compared to other experiences though an extensive literature review.

METHODS

We retrospectively analysed a single surgeon series of the last 10 years. From January 2014 to December 2023, 36 patients underwent urgent or emergency RS. The robotic devices used were Da Vinci Si (15 cases) and Xi (21 cases).

RESULTS

36 (4.3%) out of 834 robotic procedures were included in our analysis: 20 (56.56%) females. The mean age was 63 years and 30% of patients were ≥ 70 years. 2 (5.55%) procedures were performed at night. No conversions to open were reported in this series. According to the Clavien-Dindo classification, 2 (5.5%) major complications were collected. Intraoperative and 30-day mortality were 0%.

CONCLUSIONS

Our study demonstrates that RS may be a useful and reliable approach also to AES and intraoperative laparoscopic complications when performed in selected hemodynamically stable patients in very well-trained robotic centers. The technology may increase the minimally invasive use and conversion rate in emergent settings in a completely robotic or hybrid approach.

Robotic versus laparoscopic general surgery in the emergency setting: a systematic review

Robot-assisted general surgery, an advanced technology in minimally invasive procedures, is increasingly employed in elective general surgery, showing benefits over laparoscopy in specific cases. Although laparoscopy remains a standard approach for common acute abdominal conditions, the role of robotic surgery in emergency general surgery remains uncertain. This systematic review aims to compare outcomes in acute general surgery settings for robotic versus laparoscopic surgeries. A PRISMA-compliant systematic search across MEDLINE, EMBASE, Science Citation Index Expanded, and the Cochrane Library was conducted. The literature review focused on articles comparing perioperative outcomes of emergency general surgery managed laparoscopically versus robot-assisted. A descriptive analysis was performed, and outcome measures were recorded. Six articles, involving 1,063 patients, compared outcomes of robotic and laparoscopic procedures. Two articles covered cholecystectomies, while the others addressed ileocaecal resection, subtotal colectomy, hiatal hernia and repair of perforated gastrojejunal ulcers. The level of evidence was low. Laparoscopic bowel resection in patients with inflammatory bowel disease (IBD) had higher complications; no significant differences were found in complications for other operations. Operative time showed no differences for cholecystectomies, but robotic approaches took longer for other procedures. Robotic cases had shorter hospital length of stay, although the associated costs were significantly higher. Perioperative outcomes for emergency robotic surgery in selected general surgery conditions are comparable to laparoscopic surgery. However, recommending robotic surgery in the acute setting necessitates a well-powered large population study for stronger evidence.

Critical considerations for the management of acute abdomen in transplant patients

The number of solid organ transplantations performed annually is increasing and are increasing in the following order: Kidney, liver, heart, lung, pancreas, small bowel, and uterine transplants. However, the outcomes of transplants are improving (organ survival > 90% after the 1st year). Therefore, there is a high probability that a general surgeon will be faced with the management of a transplant patient with acute abdomen. Surgical problems in immunocompromised patients may not only include graft-related problems but also nongraft-related problems. The perioperative regulation of immunosuppression, the treatment of accompanying problems of immunosuppression, the administration of cortisol and, above all, the realization of a rapidly deteriorating situation and the accurate evaluation and interpretation of clinical manifestations are particularly important in these patients. The perioperative assessment and preparation includes evaluation of the patient's cardiovascular system and determining if the patient has hypertension or suppression of the hypothalamic-pituitary-adrenal axis, or if the patient has had any coagulation mechanism abnormalities or thromboembolic episodes. Immunosuppression in transplant patients is associated with the use of calcineurin inhibitors, corticosteroids, and antiproliferation agents. Many times, the clinical picture is atypical, resulting in delays in diagnosis and treatment and leading to increased morbidity and mortality. Multidetector computed tomography is of utmost importance for early diagnosis and management. Transplant recipients are prone to infections, especially specific infections caused by cytomegalovirus and Clostridium difficile, and they are predisposed to intraoperative or postoperative complications that require great care and vigilance. It is necessary to follow evidence-based therapeutic protocols. Thus, it is required that the clinician choose the correct therapeutic plan for the patient (conservative, emergency open surgery or minimally invasive surgery, including laparoscopic or even robotic surgery).

The role of RObotic surgery in EMergency setting (ROEM): protocol for a multicentre, observational, prospective international study on the use of robotic platform in emergency surgery

BACKGROUND

Robotic surgery has gained widespread acceptance in elective interventions, yet its role in emergency procedures remains underexplored. While the 2021 WSES position paper discussed limited studies on the application of robotics in emergency general surgery, it recommended strict patient selection, adequate training, and improved platform accessibility. This prospective study aims to define the role of robotic surgery in emergency settings, evaluating intraoperative and postoperative outcomes and assessing its feasibility and safety.

METHODS

The ROEM study is an observational, prospective, multicentre, international analysis of clinically stable adult patients undergoing robotic surgery for emergency treatment of acute pathologies including diverticulitis, cholecystitis, and obstructed hernias. Data collection includes patient demographics and intervention details. Furthermore, data relating to the operating theatre team and the surgical instruments used will be collected in order to conduct a cost analysis. The study plans to enrol at least 500 patients from 50 participating centres, with each centre having a local lead and collaborators. All data will be collected and stored online through a secure server running the Research Electronic Data Capture (REDCap) web application. Ethical considerations and data governance will be paramount, requiring local ethical committee approvals from participating centres.

DISCUSSION

Current literature and expert consensus suggest the feasibility of robotic surgery in emergencies with proper support. However, challenges include staff training, scheduling conflicts with elective surgeries, and increased costs. The ROEM study seeks to contribute valuable data on the safety, feasibility, and cost-effectiveness of robotic surgery in emergency settings, focusing on specific pathologies. Previous studies on cholecystitis, abdominal hernias, and diverticulitis provide insights into the benefits and challenges of robotic approaches. It is necessary to identify patient populations that benefit most from robotic emergency surgery to optimize outcomes and justify costs.

Robotic-assisted treatment of paraesophageal hernias in the emergency setting: a retrospective study

Emergency treatment of paraesophageal hernias can be carried out through laparotomy or minimally invasive approaches, however, evidence in this regard is weak. The aim of our study was to assess safety and feasibility of the robotic-assisted treatment of paraesophageal hernias in the emergency setting. At the Bellinzona e Valli Regional Hospital, Switzerland, we conducted a retrospective analysis of patients operated on from January 2020 to January 2024 with robotic surgery for emergency presentation of paraesophageal hernias. Demographic and clinical details, operative techniques, and postoperative outcomes were collected and analyzed. Out of 82 patients who underwent robotic-assisted paraesophageal hernia repair, 17 were treated in the emergency setting. Median age was 79 years (IQR 77-85), 3 (17.6%) patients were male, and median BMI was 23.9 kg/m2 (IQR 21.0-26.0). Most frequent presentation symptoms were pain (100%), regurgitation (88.2%), and dyspnea (17.6%). No intraoperative complication, conversion to open surgery or stomach resections were recorded. Two complications of grade 3 according to the Clavien-Dindo classification and one of grade 2 occurred; all were successfully treated until resolution. The median length of hospital stay was 8 days (IQR 5-16). After a mean follow-up of 15.9 months (IQR 6.5-25.6) only two small axial asymptomatic recurrences that required no treatment. Despite limitations, our study demonstrated a very low rate of intra- and postoperative complications, likely supporting the safety and feasibility of robotic-assisted treatment for paraesophageal hernias in emergency settings. Larger studies with a control arm are needed to validate our initial findings.

Is implementation of robotic-assisted procedures in acute care general surgery cost-effective?

Over the past 2 decades, the use and importance of robotic surgery in minimally invasive surgery has increased. Across various surgical specialties, robotic technology has gained popularity through its use of 3D visualization, optimal ergonomic positioning, and precise instrument manipulation. This growing interest has also been seen in acute care surgery, where laparoscopic procedures are used more frequently. Despite the growing popularity of robotic surgery in the acute care surgical realm, there is very little research on the utility of robotics regarding its effects on health outcomes and cost-effectiveness. The current literature indicates some value in utilizing robotic technology in specific urgent procedures, such as cholecystectomies and incarcerated hernia repairs; however, the high cost of robotic surgery was found to be a potential barrier to its widespread use in acute care surgery. This narrative literature review aims to determine the cost-effectiveness of robotic-assisted surgery (RAS) in surgical procedures that are often done in urgent settings: cholecystectomies, inguinal hernia repair, ventral hernia repair, and appendectomies.

Knowledge Transfer and Networking Upon Implementation of a Transdisciplinary Digital Health Curriculum in a Unique Digital Health Training Culture: Prospective Analysis

Background

Digital health has been taught at medical faculties for a few years. However, in general, the teaching of digital competencies in medical education and training is still underrepresented.

Objective

This study aims to analyze the objective acquisition of digital competencies through the implementation of a transdisciplinary digital health curriculum as a compulsory elective subject at a German university. The main subject areas of digital leadership and management, digital learning and didactics, digital communication, robotics, and generative artificial intelligence were developed and taught in a transdisciplinary manner over a period of 1 semester.

Methods

The participants evaluated the relevant content of the curriculum regarding the competencies already taught in advance during the study, using a Likert scale. The participants' increase in digital competencies were examined with a pre-post test consisting of 12 questions. Statistical analysis was performed using an unpaired 2-tailed Student t test. A P value of <.05 was considered statistically significant. Furthermore, an analysis of the acceptance of the transdisciplinary approach as well as the application of an alternative examination method (term paper instead of a test with closed and open questions) was carried out.

Results

In the first year after the introduction of the compulsory elective subject, students of human medicine (n=15), dentistry (n=3), and medical biotechnology (n=2) participated in the curriculum. In total, 13 participants were women (7 men), and 61.1% (n=11) of the participants in human medicine and dentistry were in the preclinical study stage (clinical: n=7, 38.9%). All the aforementioned learning objectives were largely absent in all study sections (preclinical: mean 4.2; clinical: mean 4.4; P=.02). The pre-post test comparison revealed a significant increase of 106% in knowledge (P<.001) among the participants.

Conclusions

The transdisciplinary teaching of a digital health curriculum, including digital teaching methods, considers perspectives and skills from different disciplines. Our new curriculum facilitates an objective increase in knowledge regarding the complex challenges of the digital transformation of our health care system. Of the 16 student term papers arising from the course, robotics and artificial intelligence attracted the most interest, accounting for 9 of the submissions.

Use of artificial intelligence in breast surgery: a narrative review

Background and Objective

We have witnessed tremendous advances in artificial intelligence (AI) technologies. Breast surgery, a subspecialty of general surgery, has notably benefited from AI technologies. This review aims to evaluate how AI has been integrated into breast surgery practices, to assess its effectiveness in improving surgical outcomes and operational efficiency, and to identify potential areas for future research and application.

Methods

Two authors independently conducted a comprehensive search of PubMed, Google Scholar, EMBASE, and Cochrane CENTRAL databases from January 1, 1950, to September 4, 2023, employing keywords pertinent to AI in conjunction with breast surgery or cancer. The search focused on English language publications, where relevance was determined through meticulous screening of titles, abstracts, and full-texts, followed by an additional review of references within these articles. The review covered a range of studies illustrating the applications of AI in breast surgery encompassing lesion diagnosis to postoperative follow-up. Publications focusing specifically on breast reconstruction were excluded.

Key Content and Findings

AI models have preoperative, intraoperative, and postoperative applications in the field of breast surgery. Using breast imaging scans and patient data, AI models have been designed to predict the risk of breast cancer and determine the need for breast cancer surgery. In addition, using breast imaging scans and histopathological slides, models were used for detecting, classifying, segmenting, grading, and staging breast tumors. Preoperative applications included patient education and the display of expected aesthetic outcomes. Models were also designed to provide intraoperative assistance for precise tumor resection and margin status assessment. As well, AI was used to predict postoperative complications, survival, and cancer recurrence.

Conclusions

Extra research is required to move AI models from the experimental stage to actual implementation in healthcare. With the rapid evolution of AI, further applications are expected in the coming years including direct performance of breast surgery. Breast surgeons should be updated with the advances in AI applications in breast surgery to provide the best care for their patients.

Robotic Cholecystectomy Remains Safe and Effective After Regular Staffing Hours

Background Robotic-assisted surgery continues to grow in popularity. Access during evenings and weekends for non-elective operations can be restricted out of safety concerns. We sought to analyze and compare outcomes of patients undergoing robotic cholecystectomy, a common urgent procedure for acute calculous cholecystitis, during regular hours versus evenings or weekends. Based on this comparison, we sought to determine if this restriction is justified. Methods We performed a retrospective analysis of 46 patients who underwent robotic cholecystectomy for acute calculous cholecystitis per 2018 Tokyo criteria by a single surgeon at a single institution between 2021 and 2022. Patients were grouped as undergoing "after-hours" cholecystectomy if the operation started at five pm or later, or anytime during the weekend (Saturday, Sunday). Demographic, perioperative, and outcome variables were tabulated and analyzed. For illustrative purposes, the data presented as median ± standard deviation were applicable. Results After-hours cholecystectomy occurred in 26 patients and regular-hours cholecystectomy occurred in 20 patients. There were no significant differences in perioperative variables between the two cohorts in terms of body mass index, age, gender, cirrhotic status, American Society of Anesthesiology score, white blood cell count, or neutrophil percentage. The after-hours group had more prior abdominal operations. There were no significant differences between the two groups in terms of operative time, estimated blood loss, or length of stay. There were no mortalities. There was one readmission in the after-hours cohort unrelated to the operation. Conclusion Robotic cholecystectomy can be safely performed on the weekends and evenings. Hospitals should make the robotic platform available during this time.

Characterization of the robotic surgery experience in minimally invasive surgery fellowships from 2010 to 2021

BACKGROUND

Robotic surgery has experienced exponential growth in the past decade. Few studies have evaluated the impact of robotics within minimally invasive surgery (MIS) fellowship training programs. The purpose of our study was to examine and characterize recent trends in robotic surgery within MIS fellowship training programs.

METHODS

De-identified case log data from the Fellowship Council from 2010 to 2021 were evaluated. Percentage of operations performed with robot assistance over time was assessed and compared to the laparoscopic and open experience. Case logs were further stratified by operative category (e.g., bariatric, hernia, foregut), and robotic experience over time was evaluated for each category. Programs were stratified by percent robot use and the experience over time within each quartile was evaluated.

RESULTS

MIS fellowship training programs with a robotic platform increased from 45.1% (51/113) to 90.4% (123/136) over the study period. The percentage of robotic cases increased from 2.0% (1127/56,033) to 23.2% (16,139/69,496) while laparoscopic cases decreased from 80.2% (44,954/56,033) to 65.3% (45,356/69,496). Hernia and colorectal case categories had the largest increase in robot usage [hernia: 0.7% (62/8614) to 38.4% (4661/12,135); colorectal 4.2% (116/2747) to 31.8% (666/2094)]. When stratified by percentage of robot utilization, current (2020-2021) programs in the > 95th percentile performed 21.8% (3523/16,139) of robotic operations and programs in the > 50th percentile performed 90.0% (14,533/16,139) of all robotic cases. The median number of robotic cases performed per MIS fellow significantly increased from 2010 to 2021 [0 (0-6) to 72.5 (17.8-171.5), p < 0.01].

CONCLUSIONS

Robotic use in MIS fellowship training programs has grown substantially in the past decade, but the laparoscopic and open experience remains robust. There remains an imbalance with the top 50% of busiest robotic programs performing over 90% of robot trainee cases. The experience in MIS programs varies widely and trainees should examine program case logs closely to confirm parallel interests.

Methods of Surgical Repair for Iatrogenic Sigmoid Colon Perforation Following Colonoscopy: A Case Report and Literature Review

Iatrogenic colonic perforation is a relatively infrequent yet perilous complication arising from both diagnostic and therapeutic colonoscopies, potentially leading to severe septic complications and increased morbidity or mortality. Given the gravity of potential complications, surgical intervention stands as the principal treatment strategy, with various modalities selected based on clinical discretion. In this context, we present the case of a patient who underwent primary laparoscopic repair following the identification of a sigmoid colon perforation during a routine colonoscopy. Intraoperatively, a Jackson-Pratt drain was placed to facilitate postoperative monitoring and drainage. The patient's hospitalization extended to a total of seven days due to sustained drainage and leukocytosis, highlighting the complexities of managing postoperative complications in such cases. This report underscores the current landscape of published data guiding the surgical management of iatrogenic colonic perforation following colonoscopy and highlights both the existing strengths and gaps within the current body of literature. As colonic perforation remains a critical concern in endoscopic procedures, a comprehensive understanding of optimal surgical interventions is crucial for minimizing patient morbidity and ensuring successful outcomes.

Training curriculum in minimally invasive emergency digestive surgery: 2022 WSES position paper

BACKGROUND

Minimally invasive surgery (MIS), including laparoscopic and robotic approaches, is widely adopted in elective digestive surgery, but selectively used for surgical emergencies. The present position paper summarizes the available evidence concerning the learning curve to achieve proficiency in emergency MIS and provides five expert opinion statements, which may form the basis for developing standardized curricula and training programs in emergency MIS.

METHODS

This position paper was conducted according to the World Society of Emergency Surgery methodology. A steering committee and an international expert panel were involved in the critical appraisal of the literature and the development of the consensus statements.

RESULTS

Thirteen studies regarding the learning curve in emergency MIS were selected. All but one study considered laparoscopic appendectomy. Only one study reported on emergency robotic surgery. In most of the studies, proficiency was achieved after an average of 30 procedures (range: 20-107) depending on the initial surgeon's experience. High heterogeneity was noted in the way the learning curve was assessed. The experts claim that further studies investigating learning curve processes in emergency MIS are needed. The emergency surgeon curriculum should include a progressive and adequate training based on simulation, supervised clinical practice (proctoring), and surgical fellowships. The results should be evaluated by adopting a credentialing system to ensure quality standards. Surgical proficiency should be maintained with a minimum caseload and constantly evaluated.
