BMC Surg 2022; 22:12. [PMID: 34998376 PMCID: PMC8742568 DOI: 10.1186/s12893-021-01441-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Accepted: 12/18/2021] [Indexed: 01/22/2023] Open
Abstract
Background Mastery of technical skills is one of the fundamental goals of surgical training for novices. Meanwhile, performing laparoscopic procedures requires exceptional surgical skills compared to open surgery. However, it is often difficult for trainees to learn through observation and practice only. Virtual reality (VR)-based surgical simulation is expanding and rapidly advancing. A major obstacle for laparoscopic trainees is the difficulty of well-performed dissection. Therefore, we developed a new VR simulation system, Lap-PASS LP-100, which focuses on training to create proper tension on the tissue in laparoscopic sigmoid colectomy dissection. This study aimed to validate this new VR simulation system. Methods A total of 50 participants were asked to perform medial dissection of the meso-sigmoid colon on the VR simulator. Forty-four surgeons and six non-medical professionals working in the National Cancer Center Hospital East, Japan, were enrolled in this study. The surgeons were: laparoscopic surgery experts with > 100 laparoscopic surgeries (LS), 21 were novices with experience < 100 LS, and five without previous experience in LS. The participants’ surgical performance was evaluated by three blinded raters using Global Operative Assessment of Laparoscopic Skills (GOALS). Results There were significant differences (P-values < 0.044) in all GOALS items between the non-medical professionals and surgeons. The experts were significantly superior to the novices in one item of GOALS: efficiency ([4(4–5) vs. 4(3–4)], with a 95% confidence interval, p = 0.042). However, both bimanual dexterity and total score in the experts were not statistically different but tended to be higher than in the novices. Conclusions Our study demonstrated a full validation of our new system. This could detect the surgeons' ability to perform surgical dissection and suggest that this VR simulator could be an effective training tool. This surgical VR simulator might have tremendous potential to enhance training for surgeons.

Abstract
INTRODUCTION Starting a minimally invasive cardiac surgery (MICS) for mitral valve repair (MVR) program is challenging as it requires a new learning curve, but compromising surgical results at the same time is not acceptable. Here, we describe our surgical educational experience of starting a new MICS program at a university heart center in Germany. METHODS A dedicated team for the new MICS program including 2 cardiac surgeons, 1 cardiac anesthetist, 1 perfusionist, and 1 scrub nurse was chosen. The use of long shafted instruments was trained in a low-cost self-assembled MICS simulator, and the EACTS endoscopic dry lab course was visited. Thereafter, 1 MICS center was visited for direct observation and peer-to-peer education for 6 weeks. The mentor observed the first 10 cases performed by the mentee. The surgical mitral valve expertise of 1 single cardiac surgeon was retrospectively analyzed between April 2016 and April 2021. RESULTS Before the implementation of the MICS-MVR program, 18 mitral valve operations have been performed through sternotomy between April 2016 and October 2018 including 12 replacements and 6 ring annuloplasties. After starting the MICS-MVR program, 73 mitral operations have been performed by the same surgeon of which 53 video-assisted through minithoracotomy (72.6%). 83.1% of the MICS procedures included complex repair (n = 38) and ring annuloplasty (n = 6). Open heart MV surgery was necessary in 20 patients due to concomitant procedures (n = 8), redo procedures (n = 2), severe endocarditis (n = 4), or contraindication for MICS such as PAD (n = 6). There have been no deaths, 1 stroke, and 1 cardiac vascular (RCX) complication. Two patients required conversion to sternotomy and one pericardiocentesis in the long term. CONCLUSION Typically, excellent exposure and high repair rates of the MV has led us offer MICS approach to a majority of patients with isolated MV disease. Careful planning and a strict mentor-mentee concept facilitated a safe startup of an MICS program in a busy university heart center.

Abstract
Liver transplantation (LT) is a complex operation that most transplant surgeons learn in fellowship. Training varies as there is lack of objective data that can be used to standardize teaching. We performed a retrospective review of our adult LT database with aim of looking at fellow's experience. Using American Society of Transplant Surgery cutoff of, at least 45 LT during fellowship, data for first 45 LT were compared to LT 45-90. Fellow's cases were also clustered in sequential groups of 15 LT and analyzed to estimate the learning curve (LC). Comparison of LT 1-45 with LT 46-90 showed significantly lower total operative times (TOT) (324 vs. 344 min) and warm ischemia times (WIT) (28 vs. 31 min) in the 45-90 group. Rates of biliary complications (23.8% vs. 16.4%) and bile leaks alone (10.3% vs. 5.5%) were significantly higher for first 45 LT. Analysis of fellows experience in sequential clusters of 15 LT showed decreasing TOT, WIT, biliary complications and rates of unplanned return to the OR with progression of fellowship. This study validates the current ASTS requirement of at least 45 LT. LC generated using these data can help individualize training and optimize outcomes through identification of areas in need of improvement.

Abstract
Purpose Precision oncology, such as next generation sequencing (NGS) molecular analysis and bioinformatics are used to guide targeted therapies. The laboratory turnaround time (TAT) is a key performance indicator of laboratory performance. This study aims to formally apply statistical process control (SPC) methods such as CUSUM and EWMA to a precision medicine programme to analyze the learning curves of NGS and bioinformatics processes. Patients and Methods Trends in NGS and bioinformatics TAT were analyzed using simple regression models with TAT as the dependent variable and chronologically-ordered case number as the independent variable. The M-estimator "robust" regression and negative binomial regression were chosen to serve as sensitivity analyses to each other. Next, two popular statistical process control (SPC) approaches which are CUSUM and EWMA were utilized and the CUSUM log-likelihood ratio (LLR) charts were also generated. All statistical analyses were done in Stata version 16.0 (StataCorp), and nominal P < 0.05 was considered to be statistically significant. Results A total of 365 patients underwent successful molecular profiling. Both the robust linear model and negative binomial model showed statistically significant reductions in TAT with accumulating experience. The EWMA and CUSUM charts of overall TAT largely corresponded except that the EWMA chart consistently decreased while the CUSUM analyses indicated improvement only after a nadir at the 82nd case. CUSUM analysis found that the bioinformatics team took a lower number of cases (54 cases) to overcome the learning curve compared to the NGS team (85 cases). Conclusion As NGS and bioinformatics lead precision oncology into the forefront of cancer management, characterizing the TAT of NGS and bioinformatics processes improves the timeliness of data output by potentially spotlighting problems early for rectification, thereby improving care delivery.

Abstract
Studies comparing right (RC) and left colectomies (LC) show higher rates of ileus in RC and higher wound infection and anastomotic leak rates in LC. However, prior studies did not include robotic procedures. We compared short-term outcomes of laparoscopic and robotic RC and LC for cancer, with sub-analysis of robotic procedures. In a retrospective review of a prospective database, preoperative factors, intraoperative events, and 30-day postoperative outcomes were compared. Student's t tests and Chi-square tests were used for continuous and categorical variables, respectively. A logistic binomial regression was performed to assess whether type of surgery was associated with postoperative complications. Between January 2014 and August 2020, 115 patients underwent minimally invasive RC or LC for cancer. Sixty-eight RC [30 (44.1%) laparoscopic, 38 (55.9%) robotic] and 47 LC [13 (27.6%) laparoscopic, 34 (72.4%) robotic] cases were included. On univariate analysis, RC patients had significantly higher overall postoperative complications but no differences in rates of ileus/small bowel obstruction, wound infection, time to first flatus/bowel movement, length of hospital stay, and 30-day readmissions. On multivariate analysis, there was no significant difference in overall complications and laparoscopic surgery had a 2.5 times higher likelihood of complications than robotic surgery. In sub-analysis of robotic cases, there was no significant difference among all outcome variables. Previously reported outcome differences between laparoscopic RC and LC for cancer may be mitigated by robotic surgery.

Abstract
BACKGROUND The subxiphoid single-port approach for thymectomy has several advantages compared with conventional lateral transthoracic approaches. However, perioperative outcomes of subxiphoid single-port thymectomy are still lacking. The objective of this study is to present our 6-year experience of subxiphoid single-port thymectomy, including our learning curve. METHODS All consecutive 49 patients undergoing subxiphoid single-port thymectomy between August 2014 and September 2020 were reviewed retrospectively. RESULTS We analyzed data of 49 patients (27 males and 22 females) with a median age of 58 years (range 49-68). Two patients presented postoperative complications. The conversion to a different approach was required in four cases. The median follow-up time was 17 months (range 3-35) and locoregional recurrence was observed in one patient. There were no intraoperative deaths and postoperative mortality. The operation time cumulative summation learning curve analysis revealed that the curves descended from the 24th case. CONCLUSIONS The subxiphoid single-port approach for thymectomy is a safe and feasible modality with few complications.

Abstract
BACKGROUND Laparoscopic resection is the treatment of choice for colorectal cancer. Rates of conversion to open surgery range between 7% and 30% and controversy exists as to the effect of this on oncologic outcomes. The objective of this study was to analyze what factors are predictive of conversion and what effect they have on oncologic outcomes. METHODS From a prospective database of patients undergoing laparoscopic surgery between 2000 and 2018 a univariate and multivariate analyses were made of demographic, pathologic, and surgical variables together with complementary treatments comparing purely laparoscopic resection with conversions to open surgery. Overall and disease-free survival were compared using the Kaplan-Meier method. RESULTS Of a total of 829 patients, 43 (5.18%) converted to open surgery. In the univariate analysis, 12 variables were significantly associated with conversion, of which left-sided resection [odds ratio (OR): 2.908; P=0.02], resection of the rectum (OR: 4.749, P=0.014), and local invasion of the tumor (OR: 6.905, P<0.01) were independently predictive factors in the multiple logistic regression. Female sex was associated with fewer conversions (OR: 0.375, P=0.012). The incidence and pattern of relapses were similar in both groups and there were no significant differences between overall and disease-free survival. CONCLUSIONS Left-sided resections, resections of the rectum and tumor invasion of neighboring structures are associated with higher rates of conversion. Female sex is associated with fewer conversions. Conversion to open surgery does not compromise oncologic outcomes at 5 and 10 years.

Abstract
The complexity associated with laparoscopic colorectal surgery requires several skills to overcome the technical difficulties related to this procedure. To overcome the technical challenges of laparoscopic surgery, a robotic approach has been introduced. Our study reports the surgical outcomes obtained by the transition from laparoscopic to robotic approach in colorectal cancer surgery to establish in which type of approach the proficiency is easier to reach. Data about the first consecutive 15 laparoscopic and the first 15 consecutive robotic cases are extracted, adopting as a comparator of proficiency the last 15 laparoscopic colorectal resections for cancer. The variables studied are operative time, number of harvested nodes, conversion rate, postoperative complications, recovery outcomes. Our analysis includes 15 patients per group. Our results show that operative time is significantly longer in the first 15 laparoscopic cases (p = 0.001). A significantly lower number of harvested nodes was retrieved in the first 15 laparoscopic cases (p = 0.003). Clavien Dindo I complication rate was higher in the first laparoscopic group, but without a significant difference among the three groups (p = 0.09). Our results show that the surgeon needed no apparent learning curve to reach their laparoscopic standards. However, further multicentric prospective studies are needed to confirm this conclusion.

Should be a locally advanced colon cancer still considered a contraindication to laparoscopic resection? Surg Endosc 2021; 36:3039-3048. [PMID: 34129086 DOI: 10.1007/s00464-021-08600-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Accepted: 06/06/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND The role of elective laparoscopic resection (LR) for the treatment of locally advanced colon cancer (LACC) is unclear. Most studies have retrospectively investigated the outcomes of LR for pT4 cancers, while clinical T4 (cT4) cancers are excluded in the large randomized controlled trials comparing LR and open resection (OR). The aim of this study was to investigate the outcomes in patients undergoing elective LR for LACC. METHODS A prospective single-institution database including consecutive patients undergoing elective LR for clinical LACC (high-risk T3 or T4 N0-2) between March 1996 and March 2017 was retrospectively reviewed. A multivariate analysis was performed to identify predictors of conversion to OR and risk factors for adverse oncologic outcomes. RESULTS A total of 300 patients undergoing LR for LACC were included. A multi-visceral resection was needed in 17 (5.7%) patients. A total of 63 (21%) LRs were converted to OR, mainly due to suspected adjacent organ invasion (82.5%) or obesity (9.5%). Overall postoperative Clavien-Dindo 3-4 complication rate was 4.7%, with no significant differences between completed and converted LRs. Final pathology showed 18 (6%) pT2, 215 (71.7%) pT3, 54 (18%) pT4a, and 13 (4.3%) pT4b cancers. A R0 resection was achieved in 98.3% of patients. On multivariate analysis, tumor size ≥ 7 cm and tumor site (splenic flexure) were the independent risk factors for conversion to OR. A pT4 colon cancer and LNR of 0.25 or greater, but not conversion to OR, were independently associated with both poorer OS and DFS. CONCLUSION(S) Clinical LACC should not be considered a contraindication to LR itself. Bulky tumors ≥ 7 cm and splenic flexure cancers are at higher risk of conversion to OR; however, there is no increased postoperative morbidity or adverse oncologic outcomes in converted patients.

Abstract
PURPOSE The advent of robotic surgery has highlighted the advantages of articulation. This dry-lab study examined the dexterity and learning effect of a new articulated laparoscopic instrument: the ArtiSential® forceps (LIVSMED, Seongnam, Republic of Korea). METHODS A peg board task was designed. Three groups of volunteers with varying levels of laparoscopic expertise were organized to perform the task: expert, intermediate and novice. The participants performed the task using articulated and straight instruments, once before a 30-min training session and once afterwards. The times required to perform the task were recorded. The performances were analyzed and compared between the groups as well as between the straight and articulated instruments. RESULTS The experts were significantly faster than the novices with both instruments before the 30-min training session (p = 0.0317 for each instrument). No significant time difference was found among the three groups after the 30-min training session. The decrease in the time required to perform the peg-transfer task with the articulated instrument was significantly greater in the novice and intermediate groups (p = 0.0159 for each group). No significant difference in time reduction was observed between the groups with the straight instrument. Regardless of the user, the articulated device was associated with faster task performance than the straight device after 8 hours of training (p = 0.0039). CONCLUSION The ArtiSential® articulated device can improve dexterity. A significantly greater learning effect was observed in the novice and intermediate groups in comparison with experts. A plateau in the learning curve was observed after a few hours of training.

Abstract
Importance Previous studies comparing emergency surgery outcomes with surgeon experience have been small or used administrative databases without controlling for patient physiology or operative complexity. Objective To evaluate the association of acute care surgeon experience with patient morbidity and mortality after emergency surgical procedures. Design, Setting, and Participants This cohort study evaluated the association of surgeon experience with emergency surgery outcomes at 5 US academic level 1 trauma centers where the same surgeons provided emergency general surgical care. A total of 772 patients who presented with a traumatic injury and required an emergency surgical procedure or who presented with or developed a condition requiring an emergency general surgical intervention were operated on by 1 of 56 acute care surgeons. Surgeon groups were divided by experience of less than 6 years (early career), 6 to 10 years (early midcareer), 11 to 30 years (late midcareer), and 30 years or more (late career) from the end of training. Surgeons with less than 3 years of experience were also compared with the entire cohort. Hierarchical logistic regression models were constructed controlling for Emergency Surgery Score, case complexity, preoperative transfusion, and trauma or emergency general surgery. Data were collected from May 2015 to July 2017 and analyzed from February to May 2020. Main Outcomes and Measures Mortality, complications, length of stay, blood loss, and unplanned return to the operating room. Results Of 772 included patients, 469 (60.8%) were male, and the mean (SD) age was 50.1 (20.0) years. Of 772 operations, 618 were by surgeons with less than 10 years of experience. Early- and late-midcareer surgeons generally operated on older patients and patients with more septic shock, acute kidney failure, and higher Emergency Surgery Scores. Patient mortality, complications, postoperative transfusion, organ-space surgical site infection, and length of stay were similar between surgeon groups. Patients operated on by early-career surgeons had higher rates of unplanned return to the operating room compared with those operated on by early-midcareer surgeons (odds ratio [OR], 0.66; 95% CI, 0.40-1.09), late-midcareer surgeons (OR, 0.34; 95% CI, 0.13-0.90), and late-career surgeons (OR, 1.11; 95% CI, 0.45-2.75). Patients operated on by surgeons with less than 3 years of experience had similar mortality compared with the rest of the cohort (OR, 1.97; 95% CI, 0.85-4.57) but higher rates of complications (OR, 2.07; 95% CI, 1.05-4.07). Conclusions and Relevance In this study, experienced surgeons generally operated on older patients with more septic shock and kidney failure without affecting risk-adjusted mortality. Increased complications and unplanned return to the operating room may improve with experience. Early-career surgeons' outcomes may be improved if they are supported while experience is garnered.

Abstract
Bakground: Laparoscopic techniques are now an integral part of the operative management of colorectal diseases. However, the specialist training that is required for this is not uniformly available. There is, therefore, a need for a structured competency-based training method so that trainees can navigate the learning curve safely. Aim. To develop a modular structured training programme for laparoscopic colorectal surgery (LCS) with the capability of ensuring competency-based progression from a novice level to independent operator. Methodology. Over the past decade, we have developed a structured approach, starting with junior surgical trainees and progressing through to consultant level, with 7 clearly defined levels of progression attending courses to achieving a trainer status. This approach allows trainees to maintain objective records of their progression and trainers to provide targeted learning opportunities. It also allows for several trainees of varying experience to be trained during the same procedure. Conclusion. Our structured training module for junior surgeons has successfully produced several competent laparoscopic colorectal surgeons in the United Kingdom and around the world. This approach may also be adaptable to training in other laparoscopic procedures as the levels of progression are generic and not procedure-specific.

Abstract
BACKGROUND The most commonly performed bariatric procedures are laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (LSG). Impact of learning curves on operative outcome has been well shown, but the necessary learning curves have not been clearly defined. This study provides a systematic review of the literature and proposes a standardization of phases of learning curves for RYGB and LSG. METHODS A systematic literature search was performed using PubMed, Web of Science, and CENTRAL databases. All studies specifying a number or range of approaches to characterize the learning curve for RYGB and LSG were selected. RESULTS A total of 28 publications related to learning curves for 27,770 performed bariatric surgeries were included. Parameters used to determine the learning curve were operative time, complications, conversions, length of stay, and blood loss. Learning curve range was 30-500 (RYGB) and 30-200 operations (LSG) according to different definitions and respective phases of learning curves. Learning phases described the number of procedures necessary to achieve predefined skill levels, such as competency, proficiency, and mastery. CONCLUSIONS Definitions of learning curves for bariatric surgery are heterogeneous. Introduction of the three skill phases competency, proficiency, and mastery is proposed to provide a standardized definition using multiple outcome variables to enable better comparison in the future. These levels are reached after 30-70, 70-150, and up to 500 RYGB, and after 30-50, 60-100, and 100-200 LSG. Training curricula, previous laparoscopic experience, and high procedure volume are hallmarks for successful outcomes during the learning curve.

Abstract
BACKGROUND Ever since transanal total mesorectal excision was introduced by Sylla and Lacy in 2010, it has become more popular among colorectal surgeons. However, some surgeons hesitate to use it, because this novel approach differs greatly from laparoscopic total mesorectal excision and requires a long learning curve. OBJECTIVE This study analyzed the learning curve of transanal total mesorectal excision procedure and compared the different phases of transanal total mesorectal excision with laparoscopic total mesorectal excision. DESIGN This is retrospective case-control study. SETTINGS We used data from the approved colorectal cancer database of the Sixth Affiliated Hospital of Sun Yat-sen University. PATIENTS The patients involved in this study underwent transanal total mesorectal excision performed by a single surgeon (L.K.) or underwent laparoscopic transanal total mesorectal excision performed by experienced surgeons. INTERVENTIONS Transanal or laparoscopic resection of mid-low rectal cancer was conducted. MAIN OUTCOMES MEASURES Perioperative complication and resection margin were measured. RESULTS A total of 342 patients were included in both groups. The learning curve of transanal total mesorectal excision was divided into 3 phases. Data show that demographics and tumor characteristics were not significantly different between the matched groups. Indeed, during phase 1, only operative time was longer than in the laparoscopic group, whereas, during phase 2, results from the transanal group were comparable with the laparoscopic group. Results show that, during phase 3, operative time, intraoperative blood loss, and postoperative hospital stay were all lower than in the laparoscopic group. Local recurrence occurred in 3 patients during phase 1 and in 1 patient during phase 2. LIMITATIONS This study was a small retrospective study and focused on just 1 surgeon performing transanal total mesorectal excision. CONCLUSIONS Short-term and histopathologic outcomes are similar compared between a transanal group and matched laparoscopic group. Transanal total mesorectal excision also provided good oncologic outcomes. See Video Abstract at http://links.lww.com/DCR/B450. ESCISIN MESORRECTAL TOTAL TRANSANAL EN EL CNCER DE RECTO MEDIOBAJO EVALUACIN DE LA CURVA DE APRENDIZAJE Y COMPARACIN DE RESULTADOS A CORTO PLAZO CON TME LAPAROSCPICA ESTNDAR ANTECEDENTES:Desde que Sylla y Lacy introdujeron la escisión mesorrectal total transanal en 2010, se ha vuelto más popular entre los cirujanos colorrectales. Sin embargo, algunos cirujanos dudan en utilizarlo, porque este nuevo método difiere mucho de la escisión mesorrectal total laparoscópica y requiere una larga curva de aprendizaje.OBJETIVO:Este estudio analizó la curva de aprendizaje del procedimiento de escisión mesorrectal total transanal y comparó las diferentes fases de la escisión mesorrectal total transanal con la escisión mesorrectal total laparoscópica.DISEÑO:Este es un estudio retrospectivo de casos y controles.ENTORNO CLINICO:Utilizamos base de datos de cáncer colorrectal aprobada del Sexto Hospital Afiliado de la Universidad Sun Yat-sen (Guangzhou, China).PACIENTES:Los pacientes involucrados en este estudio fueron sometidos a escisión mesorrectal total transanal realizada por un solo cirujano (LK) o se sometieron a escisión mesorrectal total transanal laparoscópica realizada por cirujanos experimentados.INTERVENCIONES:Resección transanal o laparoscópica de cáncer de recto medio-bajo.PRINCIPALES MEDIDAS DE VOLARCION:complicación perioperatoria y margen de resección.RESULTADOS:Se incluyó un total de 342 pacientes en ambos grupos. La curva de aprendizaje de la escisión mesorrectal total transanal se dividió en tres fases. Los datos muestran que las características demográficas y tumorales no fueron significativamente diferentes entre los grupos emparejados. De hecho, durante la fase 1, solo el tiempo operatorio fue más largo que en el grupo laparoscópico. Mientras que durante la fase 2, los resultados del grupo transanal fueron comparables a los del grupo laparoscópico. Los resultados muestran que durante la fase 3, el tiempo operatorio, la pérdida de sangre intraoperatoria y la estancia hospitalaria postoperatoria fueron menores que en el grupo laparoscópico. La recurrencia local ocurrió en 3 pacientes durante la fase 1 y en 1 paciente durante la fase 2.LIMITACIONES:Este estudio fue un estudio retrospectivo pequeño y se centró en un solo cirujano que realizaba la escisión mesorrectal total transanal.CONCLUSIÓN:Los resultados a corto plazo e histopatológicos son similares en comparación entre el grupo transanal y el grupo laparoscópico emparejado. La escisión mesorrectal total transanal también proporcionó buenos resultados oncológicos. Consulte Video Resumen en http://links.lww.com/DCR/B450.

Abstract
Surgery for inflammatory bowel diseases (IBD) management has passed through an important evolution over the last decades, with innovative strategies and new technologies, especially in minimally invasive surgery (MIS) approaches. MIS procedures for IBD include multiport laparoscopy, single-port surgery, robotics, and the use of transanal platforms. These approaches can be used in the surgical management of both Crohn's disease (CD) and ulcerative colitis (UC). There are significant peculiarities in the surgical field in CD and UC, and their perfect understanding are directly related to better outcomes in IBD patients, as a consequence of improvement in knowledge by IBD surgeons. Different strategies to train colorectal surgeons were developed worldwide, for better application of MIS, usually for malignant or non-IBD benign diseases. There is a significant lack of evidence in specific training strategies for MIS in the IBD field. In this review, the authors outline the importance of adequate surgical training in IBD MIS, by discussing the current evidence on different approaches and emphasizing the need for better training protocols included in multidisciplinary teams in IBD centers throughout the globe.

Abstract
Surgery is an ever-evolving discipline and continually incorporates new technologies that have improved the ability of the operating room surgeon to perform. The next generation of minimally invasive surgery includes laparoscopic and robotic-assisted procedures. Graduating residents may be expected to have the skills to perform common colorectal procedures using these technologies, and residency programs are developing curriculums to teach these skills. Minimally invasive techniques are challenging and learning only by observation and practice alone is difficult. This requires dedicated training and mentoring. New simulation methods have been conceived specifically for minimally invasive procedures, and these embrace a combination of virtual reality simulators and box trainers, with animal and human tissue, as well as synthetic materials. The aim of this review is to provide an overview of training in minimally invasive colorectal surgery with a focus on different types of simulators that build the basis to develop and include a multistep training approach in a structured training curriculum for minimally invasive colorectal procedures.

Abstract
Open fetal surgery for spina bifida (SB) is safe and effective yet invasive. The growing interest in fetoscopic SB repair (fSB-repair) prompts the need for appropriate training. We aimed to develop and validate a high-fidelity training model for fSB-repair. fSB-repair was simulated in the abdominal cavity and on the stomach of adult rabbits. Laparoscopic fetal surgeons served either as novices (n = 2) or experts (n = 3) based on their experience. Technical performance was evaluated using competency Cumulative Sum (CUSUM) analysis and the group splitting method. Main outcome measure for CUSUM competency was a composite binary outcome for surgical success, i.e. watertight repair, operation time ≤ 180 min and Objective-Structured-Assessment-of-Technical-Skills (OSATS) score ≥ 18/25. Construct validity was first confirmed since competency levels of novices and experts during their six first cases using both methods were significantly different. Criterion validity was also established as 33 consecutive procedures were needed for novices to reach competency using learning curve CUSUM, which is a number comparable to that of clinical fSB-repair. Finally, we surveyed expert fetal surgeons worldwide to assess face and content validity. Respondents (26/49; 53%) confirmed it with ≥ 71% of scores for overall realism ≥ 4/7 and usefulness ≥ 3/5. We propose to use our high-fidelity model to determine and shorten the learning curve of laparoscopic fetal surgeons and retain operative skills.

Abstract
Surgical training in the UK and Ireland has faced challenges following the implementation of the European Working Time Directive and postgraduate training reform. The health services are undergoing a digital transformation; digital technology is remodelling the delivery of surgical care and surgical training. This review aims to critically evaluate key issues in laparoscopic general surgical training and the digital technology such as virtual and augmented reality, telementoring and automated workflow analysis and surgical skills assessment. We include pre-clinical, proof of concept research and commercial systems that are being developed to provide solutions. Digital surgical technology is evolving through interdisciplinary collaboration to provide widespread access to high-quality laparoscopic general surgery training and assessment. In the future this could lead to integrated, context-aware systems that support surgical teams in providing safer surgical care.

Long-term oncological outcomes of low anterior resection for rectal cancer with and without preservation of the left colic artery: a retrospective cohort study. BMC Cancer 2021; 21:171. [PMID: 33596860 PMCID: PMC7890901 DOI: 10.1186/s12885-021-07848-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Accepted: 01/27/2021] [Indexed: 12/24/2022] Open
Abstract
Background There is uncertainty in the literature about preserving the left colic artery (LCA) during low anterior resection for rectal cancer. We analyzed the effect of preserving the LCA on long-term oncological outcomes. Methods We retrospectively collected clinicopathological and follow-up details of patients who underwent low anterior resection for rectal cancer in the General Surgery Department of Guangdong Provincial People’s Hospital, from January 2014 to December 2015. Cases were divided into low ligation (LL), LCA preserved, or high ligation (HL), LCA not preserved, of the inferior mesenteric artery. The 5-year overall survival (OS) and disease-free survival (DFS) rates were compared between the two groups. Results Altogether, there were 221 and 295 cases in the LL group and HL groups, respectively. Operating time in the LL group was significantly longer than in the HL group (224.7 vs. 211.7 min, p = 0.039). Postoperative 30-day mortality, early complications including anastomotic leakage showed no significant differences between the LL and HL groups (postoperative 30-day mortality, 0.9% LL, 1.4% HL, p = 0.884; early complications, 41.2% LL, 38.3% HL, p = 0.509; anastomotic leakage 8.6% LL, 13.2% HL, p = 0.100). The median follow-up periods were 51.4 (7–61) months in the LL group and 51.2 (8–61) months in the HL group. During follow-up, the percentages of patients who died, had local recurrence, or had metastases were 39.8, 7.7, and 38.5%, respectively, in the LL group and 39, 8.5, and 40%, respectively, in the HL group; these differences were not significant (all p > 0.05). The 5-year OS and DFS were 69.6 and 59.6% in the LL group, respectively, and 69.1 and 56.2% in the HL group, respectively; these differences were not significant (all p > 0.05). After stratification by tumor-node-metastasis stage, the difference between the 5-year OS and DFS for stages I, II, and III cancer were not significant (all p > 0.05). Conclusions The long-term oncological outcomes of LL group are comparable with HL group. LL cannot be supported due to the absence of lower complication rates and the longer operating times.

Abstract
BACKGROUND Total ankle arthroplasty is an increasingly effective option for the treatment of end-stage arthritis. One recent innovation utilizes a transfibular, lateral approach. Like any new system, there is likely a learning curve associated with its use. We analyzed a series of patients who received a total ankle arthroplasty via a transfibular approach to state if it is possible to identify and to evaluate effects of a learning curve in the use of this novel total ankle replacement system. METHODS 76 consecutive patients meeting inclusion and exclusion criteria were retrospectively analyzed. All patients had a minimum of 24 months of follow-up. Intraoperative parameters, preoperative and postoperative subjective outcome scores, radiographic parameters, and complications were recorded and evaluated. RESULTS There were significant learning curve effects on various surgical and postoperative parameters. Surgical time decreased with the curve stabilizing after the 16th patient. With regard to patient outcomes, a learning curve was identified for the VAS, AOFAS, and SF-12 MCS scores. The number of patients required to stabilize these curves were 21, 13, and 16, respectively. Alignment as measured by alpha and gamma angles also improved with experience, with the curves stabilizing at 18 and 15 patients, respectively. There was a larger number cases required for complication rates, with the curve stabilizing after the 39th patient. No significant learning curve was found for ankle ROM, SF-12 PCS, beta angle, tibio-talar ratio (TTR), or tibio-talar surface angle (TTS). CONCLUSIONS This study demonstrates a significant learning curve with respect to operative time, patient outcomes, and radiographic parameters. Extrapolating this information, we urge surgeons to adequately familiarize themselves with any new implant through a training program in a high-volume center. LEVEL OF EVIDENCE IV, case series.

Abstract
BACKGROUND Despite reports of increasing adoption of robotics in colorectal surgery worldwide, data regarding its uptake in Australasia are lacking. This study examines the trends of robotic colorectal surgery in Australia during the last 10 years. METHODS Data from patients undergoing robotic colorectal surgery with the da Vinci robotic platform between 2010 and 2019 were obtained. Overall, numbers of specific colorectal procedures across Australia were obtained from the Medicare Benefit Schedule data over the same period. Pearson's correlation analysis was used to determine the statistical trends of overall and specific robotic colorectal procedures over time. RESULTS A total of 6110 robotic general surgery procedures were performed across Australia during the study period. Of these, 3522 (57.6%) were robotic colorectal procedures. An increasing trend of overall robotic colorectal procedures was seen over 10 years (Pearson's coefficient of 0.875; P = 0.001). While this applied to both the public and private sectors, 90.7% of the procedures were undertaken in the private sector. Restorative rectal resections, rectopexies, and right hemicolectomies accounted for 82.6% of the robotic colorectal procedures performed during this period with an increasing trend seen over time for each intervention. Moreover, a robotic approach was utilized in 12.5%, 41.0% and 9.0% of all restorative rectal resections, rectopexies and right hemicolectomies undertaken in Australia during 2019, respectively. CONCLUSION Robotic colorectal surgery has increased dramatically in Australia over the last 10 years, especially in the private sector. Penetration of robotic colorectal surgery in the public healthcare system will require focussed cost-benefit evaluations and governmental investment.

Abstract
Background Laparoscopic colorectal surgery (LCRS) was first described in 1991, and its safety, efficacy and patient benefit were adequately documented in literature. However, its penetration and acceptability is poor in most countries, due to its long learning curve and lack of surgeons training and confidence. A Minimal Access Surgery (MAS) Training Center in Mumbai has over the last 7 years trained more than 8000 surgeons in various MAS specialities. The centre has initiated courses for LCRS training. Materials and Methods The anatomy of the pig colon is very different from human anatomy. The pig colon anatomy is altered to mimic human colon anatomy in the porcine abdomen, permitting hands-on practice on most laparoscopic colorectal surgical procedures, as part of the LCRS training course, under mentorship of expert faculty, who simultaneously assess participants performance. Results Each participant performs and assists for at least three procedures and is evaluated at each step of the procedure by a structured format. The overall evaluation by Faculty which though subjective, is detailed and favourable. Feedback of each participant is good and acceptable as a very helpful course. Conclusion This porcine model is ideal for hands-on training for LCRS. Participants achieve a good degree of skill level and confidence in performing LCRS procedures on fresh bleeding porcine cadaver models. The centre is factual and pragmatic and stresses that it needs more than a course to make a safe surgeon; operation room mentorship is the finishing school.

Abstract
AIM This study aimed to present our experience with robotic colorectal surgery since its establishment at our institution in 2009. By examining the outcomes of over 500 patients, our experience provides a basis for assessing the introduction of a robotic platform in a colorectal practice. Specific measures investigated include intraoperative data and postoperative outcomes for all operations using the robotic platform. In addition, for our most commonly performed operations we wished to analyse the learning curve to improve operative proficiency. This is the largest single-surgeon robotic database analysed to date. METHOD A prospectively maintained database of patients who underwent robotic colorectal surgery by a single surgeon at the George Washington University Hospital was retrospectively reviewed. Demographic data and perioperative outcomes were assessed. Additionally, an operating time learning curve analysis was performed. RESULTS Inclusion criteria identified 502 patients who underwent robotic colorectal surgery between October 2009 and December 2018. The most common indications for surgery were diverticulitis (22.9%), colon adenocarcinoma (22.1%) and rectal adenocarcinoma (19.5%). The most common operations were anterior/low anterior resection (33.9%), right hemicolectomy/ileocaecectomy (24.9%) and left hemicolectomy/sigmoidectomy (21.9%). The rate of conversion to open surgery was 4.8%. The most common postoperative complications were wound infection (5.0%), anastomotic leakage (4.0%) and abscess formation (2.8%). The operating time learning curve plateaued at 55-65 cases for anterior and low anterior resection and 35-45 cases for left hemicolectomy and sigmoidectomy. A clear learning curve was not seen in right hemicolectomy. CONCLUSION Robotic-assisted surgery can be performed in a diverse colorectal practice with low rates of conversion and postoperative complications. Plateau performance was achieved after 65 anterior/low anterior resections and 45 left and sigmoid colectomies.

Abstract
Cumulative sum (CUSUM) plots and methods have wide-ranging applications in healthcare. We review and discuss some issues related to the analysis of surgical learning curve (LC) data with a focus on three types of CUSUM statistical approaches. The underlying assumptions, benefits, and weaknesses of each approach are given. Our primary conclusion is that two types of CUSUM methods are useful in providing visual aids, but are subject to overinterpretation due to the lack of well-defined decision rules and performance metrics. The third type is based on plotting the CUSUM of the differences between observations and their average value. We show that this commonly applied retrospective method is frequently interpreted incorrectly and is thus unhelpful in the LC application. Curve-fitting methods are more suitable for meeting many of the goals associated with the study of surgical LCs.

Abstract
Background Although a larger proportion of colorectal surgeries have been performed laparoscopically in the last few years, a steep learning curve prevents us from considering laparoscopic colorectal surgery as the gold standard technique for treating disease entities in the colon and rectum. The purpose of this single centre study was to determine, using various parameters and following a well-structured and standardized surgical procedure, the adequate number of cases after which a single surgeon qualified in open surgery but with no previous experience in laparoscopic colorectal surgery and without supervision, can acquire proficiency in this technique. Methods From 2012 to 2019, 112 patients with pathology in the rectum and colon underwent laparoscopic colorectal resection by a team led by the same surgeon. The patients were divided into two groups (group A:50 – group B:62) and their case records and histopathology reports were examined for predefined parameters, statistically analysed and compared between groups. Results There was no significant difference between groups in the distribution of conversions (p = 0.635) and complications (p = 0.637). Patients in both groups underwent surgery for the same median number of lymph nodes (p = 0.145) and stayed the same number of days in the hospital (p = 0.109). A statistically important difference was found in operation duration both for the total (p = 0.006) and for each different type of colectomy (sigmoidectomy: p = 0.026, right colectomy: p = 0.013, extralevator abdominoperineal resection: p = 0.050, low anterior resection: p = 0.083). Conclusions Taking into consideration all the parameters, it is our belief that a surgeon acquires proficiency in laparoscopic colorectal surgery after performing at least 50 diverse cases with a well structured and standardized surgical procedure.

Abstract
Surgical techniques have evolved over the past few decades, and minimally invasive surgery has been rapidly adapted to become a preferred operative approach for treating colorectal diseases. However, many of the procedures remain a technical challenge for surgeons to perform laparoscopically, which has prompted the development of robotic platforms. Robotic surgery has been introduced as the latest advance in minimally invasive surgery. The present article provides an overview of robotic rectal surgery and describes many advances that have been made in the field over the past two decades. More specifically, the introduction of the robotic platform and its benefits, and the limitations of current robotic technology, are discussed. Although the main advantages of robotic surgery over conventional laparoscopy appear to be lower conversion rates and better surgical specimen quality, oncological and functional outcomes appear to be similar to those of other alternatives. Other potential benefits include earlier recovery of voiding and sexual function after robotic total mesorectal excision. Nevertheless, the costs and lack of haptic feedback remain the primary limitations to the widespread use of robotic technology in the field.

Abstract
BACKGROUND A surgical learning period may be quantified after which operative duration is significantly reduced. We sought to retrospectively quantify and compare surgeon's learning experience for total shoulder arthroplasty and reverse shoulder arthroplasty. METHODS We reviewed 2055 shoulder arthroplasty cases from 2011 to 2015 for four early-career and four later-career fellowship-trained shoulder surgeons from four institutions. We plotted consecutive case number versus operative time for each surgeon separately for total shoulder arthroplasty or reverse shoulder arthroplasty. Two-step regression approach was used to determine a plateau point or end of the learning period. Additionally, the mean annual volume of reverse shoulder arthroplasty and total shoulder arthroplasty for each surgeon was plotted against mean surgery duration. Early- and later-career surgeons were compared with regression analysis. RESULTS Early-career surgeons demonstrated a significant decrease in operative time with increasing annual case volume for reverse shoulder arthroplasty (p = 0.01; m = -1.1) and total shoulder arthroplasty (p = 0.02; m = -0.8). Three of four early-career surgeons reached a plateau point for either reverse shoulder arthroplasty or total shoulder arthroplasty between 12 and 86 cases. CONCLUSION For only early-career surgeons, higher case volume yields decreased operative duration, with improvement more pronounced for reverse shoulder arthroplasty compared to total shoulder arthroplasty. Though the learning period varies, it may be fewer than 90 cases.

Abstract
BACKGROUND Robotic colorectal cancer surgery is widely accepted and applied. However, there is still no objective and comprehensive assessment on the data of nationwide multicenter series. METHOD A total of 28 medical centers in Mainland China participated in this nationwide retrospective observational study. From the first case performed in each center to the last until December 2017, patients with robotic resection for primary tumor and pathologically confirmed colorectal adenocarcinoma were consecutively enrolled. Clinical, pathological and follow-up data were collected and analyzed. RESULTS A total of 5389 eligible patients were finally enrolled in this study, composing 72.2% of the total robotic colorectal surgery volume of Mainland China in the same period. For resections of one bowel segment of primary tumor, the postoperative mortality rate was 0.08% (4/5063 cases), and the postoperative complication rate (Clavien-Dindo grade II or higher) was 8.6% (434/5063 cases). For multiple resections, the postoperative mortality rate was 0.6% (2/326 cases), and the postoperative complication rate was 16.3% (53/326 cases). Out of 2956 patients receiving sphincter-preserving surgery in only primary resection, 130 (4.4%) patients had anastomotic leakage. Traditional low anterior resection (tumor at middle rectum) (OR 2.384, P < 0.001), traditional low anterior resection (tumor at low rectum) (OR 1.968, P = 0.017) and intersphincteric resection (OR 5.468, P = 0.006) were significant independent risk factors for anastomotic leakage. Female gender (OR 0.557, P = 0.005), age ≥ 60 years (OR 0.684, P = 0.040), and preventive stoma (OR 0.496, P = 0.043) were significant independent protective factors. Body mass index, preoperative chemotherapy/radiotherapy, tumor size, and TNM stage did not independently affect the occurrence of anastomotic leakage. CONCLUSION Robotic colorectal cancer surgery was safe and reliable and might have advantages in patients at high risk of anastomotic leakage.

Inequalities in access to minimally invasive general surgery: a comprehensive nationwide analysis across 20 years. Surg Endosc 2020; 35:6227-6243. [PMID: 33206242 PMCID: PMC8523463 DOI: 10.1007/s00464-020-08123-0] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Accepted: 10/21/2020] [Indexed: 12/18/2022]
Abstract
Background Minimally invasive surgery (MIS) has profoundly changed standards of care and lowered perioperative morbidity, but its temporal implementation and factors favoring MIS access remain elusive. We aimed to comprehensibly investigate MIS adoption across different surgical procedures over 20 years, identify predictors for MIS amenability and compare propensity score-matched outcomes among MIS and open surgery. Methods Nationwide retrospective analysis of all hospitalizations in Switzerland between 1998 and 2017. Appendectomies (n = 186,929), cholecystectomies (n = 57,788), oncological right (n = 9138) and left hemicolectomies (n = 21,580), rectal resections (n = 13,989) and gastrectomies for carcinoma (n = 6606) were included. Endpoints were assessment of temporal MIS implementation, identification of predictors for MIS access and comparison of propensity score-matched outcomes among MIS and open surgery. Results The rates of MIS increased for all procedures during the study period (p ≤ 0.001). While half of all appendectomies were performed laparoscopically by 2005, minimally invasive oncological colorectal resections reached 50% only by 2016. Multivariate analyses identified older age (p ≤ 0.02, except gastrectomy), higher comorbidities (p ≤ 0.001, except rectal resections), lack of private insurance (p ≤ 0.01) as well as rural residence (p ≤ 0.01) with impaired access to MIS. Rural residence correlated with low income regions (p ≤ 0.001), which themselves were associated with decreased MIS access. Geographical mapping confirmed strong disparities for rural and low-income areas in MIS access. Matched outcome analyses revealed benefits of MIS for length of stay, decreased surgical site infection rates for MIS appendectomies and cholecystectomies and higher mortality for open cholecystectomies. No consistent morbidity or mortality benefit for MIS compared to open colorectal resections was observed. Conclusion Unequal access to MIS exists in disfavor of older and more comorbid patients and those lacking private insurance, living in rural areas, and having lower income. Efforts should be made to ensure equal MIS access regardless of socioeconomic or geographical factors.

Abstract
Introduction Laparoscopic colorectal surgery has become widely used in treating colorectal cancer. Multicenter studies have shown that laparoscopy decreases postoperative complications and provides equivalent long-term oncological results compared to open surgery. Previous studies were conducted in high-volume institutions, with selected patients, which may influence the reported outcome of laparoscopy. Methods All patients with colorectal cancer that underwent surgery for a primary tumor between 2005 and 2015 in the Lapland Central Hospital were retrospectively collected. We retrieved data on the primary surgical outcome and complications within the first 30 days after surgery from patient records. We surveyed the national patient registry to determine long-term oncological results and patient survival. Results We identified 349 patients treated for colorectal cancer during 2005-2015. Of these, 219 patients (median age 71 years) underwent laparoscopy and 130 (median age 72 years) underwent open surgery. The 5-year disease-specific survival rates for stages I-III colon cancer were 83.3 and 87.7%, respectively. The 3-year disease-specific survival rates for stages I-III rectal cancer were 86.1 and 65.0%, respectively. Conclusion Our results showed that the introduction of laparoscopic colorectal surgery for treating cancer in a rural, small-volume hospital provided short- and long-term results comparable to findings from previous studies conducted in high-volume centers. Therefore, laparoscopy should be considered the treatment of choice for colorectal cancer in small, rural clinics.

Abstract
Robotic surgery has progressively gained popularity in the treatment of rectal cancer. However, only a few studies on its oncologic effectiveness are currently present, with contrasting results. The purpose of this study is to report a single surgeon’s experience on robotic rectal resection (RRR) for cancer, focusing on the analysis of oncologic outcomes, both in terms of pathological features and long-term results. One-hundred and twenty-two consecutive patients who underwent RRR for rectal cancer from January 2013 to December 2019 were retrospectively enrolled. Patients’ characteristics and perioperative outcomes were collected. The analyzed oncologic outcomes were pathological features [distal (DM), circumferential margin (CRM) status and quality of mesorectal excision (TME)] and long-term outcomes [overall (OS) and disease-free survival (DFS)]. The mean operative time was 275 (± 60.5) minutes. Conversion rate was 6.6%. Complications occurred in 27 cases (22.1%) and reoperation was needed in 2 patients (1.5%). The median follow-up was 30.5 (5.9–86.1) months. None presented DM positivity. CRM positivity was 2.5% (2 cases) while a complete TME was reached in 94.3% of cases (115 patients). Recurrence rate was 5.7% (2 local, 4 distant and 1 local plus distant tumor relapse). OS and DFS were 90.7% and 83%, respectively. At the multivariate analysis, both CRM positivity and near complete/incomplete TME were recognized as negative prognostic factors for OS and DFS. Under appropriate logistic and operative conditions, robotic surgery for rectal cancer proves to be oncologically effective, with adequate pathological results and long-term outcomes. It also offers acceptable peri-operative outcomes, further confirming the safety and feasibility of the technique.

Abstract
Colorectal surgery has been revolutionised towards minimally invasive surgery with the emergence of enhanced recovery protocol after surgery initiatives. However, laparoscopic colectomy has yet to be widely adopted, due mainly to the steep learning curve. We aim to review and discuss the methods of overcoming these learning curves by accelerating the competency level of the trainees without compromising patient safety. To provide this mini review, we assessed 70 articles in PubMed that were found through a search comprised the keywords laparoscopic colectomy, minimal invasive colectomy, learning curve and surgical education. We found England's Laparoscopic Colorectal National Training Programme (LAPCO-NTP) England to be by far the most structured programme established for colorectal surgeons, which involves pre-clinical and clinical phases that end with an assessment. For budding colorectal trainees, learning may be accelerated by simulator-based training to achieve laparoscopic dexterity coupled with an in-theatre proctorship by field experts. Task-specific checklists and video recordings are essential adjuncts to gauge progress and performance. As competency is established, careful case selections with the proctor are essential to maintain motivation and ensure safe performances. A structured programme to establish competency is vital to help both the proctor and trainee gauge real-time progress and performance. However, training systems both inside and outside the operating theatre (OT) are equally useful to achieve the desired performance.

Abstract
BACKGROUND Safety and feasibility of robotic colorectal surgery has been reported as increasing over the last decade. However safe implementation and adaptation of such a programme with comparable morbidities and acceptable oncological outcomes remains a challenge in a busy tertiary unit. We present our experience of implementation and adaptation of a structured robotic colorectal programme in a high-volume center in the United Kingdom. METHODS Two colorectal surgeons underwent a structured robotic colorectal training programme consisting of time on simulation console, dry and wet laboratory courses, case observation, and initial mentoring. Data were collected on consecutive robotic colorectal cancer resections over a period of 12 months and compared with colorectal cancer resections data of the same surgeons' record prior to the adaptation of the new technique. Patient demographics including age, gender, American Society of Anesthesiologist score (ASA), Clavien-Dindo grading, previous abdominal surgeries, and BMI were included. Short-term outcomes including conversion to open, length of stay, return to theatre, 30- and 90-days mortality, blood loss, and post-operative analgesia were recorded. Tumour site, TNM staging, diverting stoma, neo-adjuvant therapy, total mesorectal excision (TME) grading and positive resection margins (R1) were compared. p values less than or equal to 0.05 were considered statistically significant. RESULTS Ninety colorectal cancer resections were performed with curative intent from June 2018 to June 2020. Thirty robotic colorectal cancer resections (RCcR) were performed after adaption of programme and were compared with 60 non-robotic colorectal cancer resections (N-RCcR) prior to implementation of technique. There was no conversion in the RCcR group; however, in N-RCcR group, five had open resection from start and the rest had laparoscopic surgery. In laparoscopic group, there were six (10.9%) conversions to open (two adhesions, three multi-visceral involvements, one intra-operative bleed). Male-to-female ratio was 20:09 in RCcR group and 33:20 in N-RCcR groups. No significant differences in gender (p = 0.5), median age (p = 0.47), BMI (p = 0.64) and ASA scores (p = 0.72) were present in either groups. Patient characteristics between the two groups were comparable aside from an increased proportion of rectal and sigmoid cancers in RCcR group. Mean operating time, and returns to theaters were comparable in both groups. Complications were fewer in RCcR group as compared to N-RCcR (16.6% vs 25%). RCcR group patients have reduced length of stay (5 days vs 7 days) but this is not statistically significant. Estimated blood loss and conversion to open surgery was significantly lesser in the robotic group (p < 0.01). The oncological outcomes from surgery including TNM, resection margin status, lymph node yield and circumferential resection margin (for rectal cancers) were all comparable. There was no 30-day mortality in either group. CONCLUSION Implementation and integration of robotic colorectal surgery is safe and effective in a busy tertiary center through a structured training programme with comparable short-term survival and oncological outcomes during learning curve.

Trainee Autonomy in Minimally Invasive General Surgery in the United States: Establishing a National Benchmark. JOURNAL OF SURGICAL EDUCATION 2020; 77:e52-e62. [PMID: 33250116 DOI: 10.1016/j.jsurg.2020.07.033] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/18/2020] [Revised: 07/14/2020] [Accepted: 07/19/2020] [Indexed: 06/12/2023]
Abstract
OBJECTIVE Minimally invasive surgery (MIS) is an integral component of General Surgery training and practice. Yet, little is known about how much autonomy General Surgery residents achieve in MIS procedures, and whether that amount is sufficient. This study aims to establish a contemporary benchmark for trainee autonomy in MIS procedures. We hypothesize that trainees achieve progressive autonomy, but fail to achieve meaningful autonomy in a substantial percentage of MIS procedures prior to graduation. SETTING/PARTICIPANTS Fifty General Surgery residency programs in the United States, from September 1, 2015 to March 19, 2020. All Categorical General Surgery Residents and Attending Surgeons within these programs were eligible. DESIGN Data were collected prospectively from attending surgeons and categorical General Surgery residents. Trainee autonomy was assessed using the 4-level Zwisch scale (Show and Tell, Active Help, Passive Help, and Supervision Only) on a smartphone application (SIMPL). MIS procedures included all laparoscopic, thoracoscopic, endoscopic, and endovascular/percutaneous procedures performed by residents during the study. Primary outcomes of interest were "meaningful autonomy" rates (i.e., scores in the top 2 categories of the Zwisch scale) by postgraduate year (PGY), and "progressive autonomy" (i.e., differences in autonomy between PGYs) in MIS procedures, as rated by attending surgeons. Primary outcomes were determined with descriptive statistics, one-way analysis of variance (ANOVA) and Z-tests. Secondary analyses compared (i) progressive autonomy between common MIS procedures, and (ii) progressive autonomy in MIS vs. non-MIS procedures. RESULTS A total of 106,054 evaluations were performed across 50 General Surgery residency programs, of which 38,985 (37%) were for MIS procedures. Attendings performed 44,842 (42%) of all evaluations, including 16,840 (43%) of MIS evaluations, while residents performed the rest. Overall, meaningful autonomy in MIS procedures increased from 14.1% (PGY1s) to 75.9% (PGY5s), with significant (p < 0.001) increases between each PGY level. Meaningful autonomy rates were higher in the MIS vs. non-MIS group [57.2% vs. 48.0%, p < 0.001], and progressed more rapidly in MIS vs. non-MIS, (p < 0.05). The 7 most common MIS procedures accounted for 83.5% (n = 14,058) of all MIS evaluations. Among PGY5s performing these procedures, meaningful autonomy rates (%) were: laparoscopic appendectomy (95%); laparoscopic cholecystectomy (93%); diagnostic laparoscopy (87%); upper/lower endoscopy (85%); laparoscopic hernia repair (72%); laparoscopic partial colectomy (58%); and laparoscopic sleeve gastrectomy (45%). CONCLUSIONS US General Surgery residents receive progressive autonomy in MIS procedures, and appear to progress more rapidly in MIS versus non-MIS procedures. However, residents fail to achieve meaningful autonomy in nearly 25% of MIS cases in their final year of residency, with higher rates of meaningful autonomy only achieved in a small subset of basic MIS procedures.

Abstract
Despite the technical limitations of minimally invasive surgery, laparoscopic total mesorectal excision (LTME) for rectal cancer has short-term advantages over open surgery, but the pathological outcomes reported in randomized clinical trials are still in controversy. Minimally invasive robotic total mesorectal excision (RTME) has recently been gaining popularity as robotic surgical systems potentially provide greater benefits than LTME. Compared to LTME, RTME is associated with lower conversion rates and similar or better genitourinary functions, but its long-term oncological outcomes have not been established. Although the operating time of RTME is longer than that of LTME, RTME has a shorter learning curve, is more convenient for surgeons, and is better for sphincter-preserving operations than LTME. The robotic surgical system is a good technical tool for minimally invasive surgery for rectal cancer, especially in male patients with narrow deep pelvises. Robotic systems and robotic surgical techniques are still improving, and the contribution of RTME to the treatment of rectal cancer will continue to increase in the future.

Abstract
BACKGROUND Revisional surgery is rapidly growing within the field of bariatric surgery. The use of robotic assisted surgery, considered controversial by many, may offer advantages in revisional bariatric surgery (RBS). There are few studies comparing laparoscopic and robotic-assisted RBS. The aim of this study is to compare the safety and outcome of laparoscopic and robotic RBS in a single accredited center. METHODS A retrospective analysis of data collected prospectively on patients undergoing either laparoscopic (L-RBS) or robotic (R-RBS) RBS between January 1, 2017 and December 31, 2019 was performed. The primary outcomes included length of stay (LOS), 30-day major and minor complication rates, readmission rates, and mortality rates. RESULTS A total of 167 patients were included in our analysis. Fifty-two patients underwent R-RBS (31%), and 115 underwent L-RBS (69%). Thirty-day major and minor complication rates for R-RBS and L-RBS were 1.9% and 5.8% vs 5.2% and 5.2%, respectively (p > .05). There was no difference in readmission rates (3.8% vs 8.7%, p > 0.05) or intraoperative blood loss (35.5 mL vs 37.4 mL, p > .05) between R-RBS and L-RBS. R-RBS resulted in a shorter length of stay when compared with L-RBS (40.2 h vs 62.6 h, p < .05). CONCLUSIONS R-RBS has a decreased, albeit non-significant, rate of 30-day major complications with no difference in minor complications, readmission rates, or intraoperative blood loss when compared with L-RBS. R-RBS resulted in a decreased length of stay when compared with L-RBS. Randomized clinical trials are needed to better elucidate our findings.

Abstract
BACKGROUND Robotic surgery has advantages in terms of the ergonomic design and expectations of shortening the learning curve, which may reduce the number of patients with adverse outcomes during a surgeon's learning period. We investigated the differences in the learning curves of robotic surgery and clinical outcomes for rectal cancer among surgeons with differences in their experiences of laparoscopic rectal cancer surgery. METHODS Patients who underwent robotic surgery for colorectal cancer were reviewed retrospectively. Patients were divided into five groups by surgeons, and their clinical outcomes were analyzed. The learning curve of each surgeon with different volumes of laparoscopic experience was analyzed using the cumulative sum technique (CUSUM) for operation times, surgical failure (open conversion or anastomosis-related complications), and local failure (positive resection margins or local recurrence within 1 year). RESULTS A total of 662 patients who underwent robotic low anterior resection (LAR) for rectal cancer were included in the analysis. Number of laparoscopic LAR cases performed by surgeon A, B, C, D, and E prior to their first case of robotic surgery were 403, 40, 15, 5, and 0 cases, respectively. Based on CUSUM for operation time, surgeon A, B, C, D, and E's learning curve periods were 110, 39, 114, 55, and 23 cases, respectively. There were no significant differences in the surgical and oncological outcomes after robotic LAR among the surgeons. CONCLUSIONS This study demonstrated the limited impact of laparoscopic surgical experience on the learning curve of robotic rectal cancer surgery, which was greater than previously reported curves.

Abstract
According to recent clinical practice guidelines, enhanced recovery programs (ERP) have been practiced to improve surgical outcomes and decrease cost. However, these are still opposed by the traditional measures in the treatment of colorectal carcinoma that is still practiced with the concept of protection of anastomosis and decrease postoperative complications. The aim of this study was to report our experience in ERP in elective open left side colonic carcinoma surgery in comparison with the conventional perioperative care. The current prospective multicenter randomized controlled study included a total of 80 adult patients with left side colonic cancer who were eligible for elective colonic resection. Included patients were randomly divided into two equal groups: group (A) where conventional perioperative care was performed and group (B) where ERP were applied. Follow-up was designed for at least 1 month to evaluate and compare hospital stay and postoperative complications. There was no statistically significant difference between the two groups as regards demographic data and preoperative comorbidities. There were statistically significant less pain (P = 0.24), less postoperative nausea and vomiting (P = 0.045), and less hospital stay (P < 0.001) in group B than group A. Otherwise, there was no statistically significant difference in comparing the rest of postoperative surgical or non-surgical complications or rates of readmissions between the two groups. ERP are safe, reliable, simple, and applicable in open left side cancer colon surgery with no negative impact over the postoperative complications in comparison with the conventional care.

Abstract
BACKGROUND This study aimed to compare short- and long-term outcomes after robotic versus laparoscopic approach in patients undergoing curative surgery for rectal cancer. METHODS Patients undergoing elective robotic and laparoscopic resection for rectal cancer were included. Perioperative clinical characteristics, postoperative short- and long-term outcomes were compared between groups. RESULTS There were 72 and 44 patients in robotic (RG) and laparoscopic (LG) groups respectively. No differences were detected regarding patients' demographics, histopathologic outcomes, conversion rates and 30-day overall postoperative complication rates. Operative time was longer in the RG (341 ± 111.7 vs. 263 ± 97.5 min, p = 0.001) and length of stay was longer in the LG (4.4 ± 1.9 vs. 6.4 ± 2.9 days, p = 0.001). The 5-year overall and disease-free survival rates were similar (97.1% and 94.9%, p = 0.78; 86.2% and 82.7%, p = 0.72) between the groups. CONCLUSION This study showed both short and long-term outcomes of a limited number of included patients between the robotic and laparoscopic surgery were similar. However, future studies and randomized trials are necessary to establish these findings.

Abstract
INTRODUCTION Contemporary pediatric data on pouch outcomes are sparse, especially in the era of laparoscopic surgeries. We aimed to assess outcomes and predictors in children with ulcerative colitis/inflammatory bowel disease (IBD)-unclassified who underwent colectomy and ileal pouch-anal anastomosis. METHODS This was a multicenter retrospective cohort study from 17 IBD centers affiliated with the pediatric IBD Porto group of ESPGHAN. An electronic REDcap system was used to collate baseline characteristics, demographic, clinical, management and surgical data, short- and long-term outcomes, and to identify potential predictors of pouch outcome. RESULTS Of the 129 patients included, 86 (67%) developed pouchitis during follow-up of median 40 months (interquartile range 26-72), of whom 33 (26%) with chronic pouchitis. Patients operated on by surgeons performing <10 pouch surgeries/year had a higher rate of chronic pouchitis (11/27 [41%] vs 8/54 [15%], P = 0.013) on both univariable and multivariable analyses and also associated with time to pouchitis (P = 0.018) and chronic pouchitis (P = 0.020). At last follow-up, overall pouch performance was rated good/excellent in 86 (74%) patients. Time from colectomy to pouch formation was not associated with pouch outcomes. Despite higher rate of nonsevere surgical complications among children undergoing colectomy at <10 years of age (7/16 [44%] vs 10/92 [11%], P = 0.003), functional outcome and pouchitis rate did not differ. CONCLUSIONS Pouchitis rate in children with ulcerative colitis/IBD unclassified is high. Surgeon experience is the major modifiable risk factor for pouch outcome. Our analyses suggest that pouch surgery can also be performed successfully in young children.

Impact of interventionalist's experience and gender on radiation dose and procedural time in CT-guided interventions-a retrospective analysis of 4380 cases over 10 years. Eur Radiol 2020; 31:569-579.

Abstract
Objectives To investigate the impact of the interventionalist’s experience and gender on radiation dose and procedural time in CT-guided interventions. Methods We retrospectively analyzed 4380 CT-guided interventions performed at our institution with the same CT scanner from 2009 until 2018, 1287 (29%) by female and 3093 (71%) by male interventionalists. Radiation dose, number of CT fluoroscopy images taken per intervention, total procedural time, type of intervention, and degree of difficulty were derived from the saved dose reports and images. All 16 interventionalists included in this analysis performed their first CT-guided interventions during the study period, and interventions performed by each interventionalist were counted to assess the level of experience for each intervention in terms of the number of prior interventions performed by her or him. The Mann-Whitney U test (MWU test), multivariate regression, and linear mixed model analysis were performed. Results Assessment of the impact of gender with the MWU test revealed that female interventionalists took a significantly smaller number of images (p < 0.0001) and achieved a lower dose-length product per intervention (p < 0.0001) while taking more time per intervention (p = 0.0001). This finding was confirmed for most types of interventions when additionally accounting for other possible impact factors in multivariate regression analysis. In linear mixed model analysis, we found that radiation dose, number of images taken per intervention, and procedural time decreased statistically significantly with interventionalist’s experience. Conclusions Radiation doses of CT-guided interventions are reduced by interventionalist’s experience and, for most types of interventions, when performed by female interventionalists. Key Points • Radiation doses in CT-guided interventions are lower when performed by female interventionalists. • Procedural times of CT-guided interventions are longer when performed by female interventionalists. • Radiation doses of CT-guided interventions decrease with the interventionalist’s experience.

Abstract
OBJECTIVES/HYPOTHESIS To assess hearing outcomes and complications of endoscopic stapes surgery by a single surgeon in a 10-year period, to compare these data with conventional microscopic procedures by the same operator, and to describe the learning curve of endoscopic stapedotomy. STUDY DESIGN Retrospective study. METHODS This is a retrospective study on patients who underwent endoscopic stapes surgery performed by the same senior surgeon, experienced both in microscopic and endoscopic techniques, between January 2009 and December 2018. Audiological data were compared, and intraoperative and postoperative complications were collected. The surgeon's last 30 cases of microscopic stapedotomy were enrolled as the control group. The results of the first 100 endoscopic stapes surgeries were analyzed separately to create a cumulative sum (CUSUM) control chart for learning curve assessment. RESULTS One hundred seventy-eight endoscopic and 30 microscopic stapes surgeries were included. In the endoscopic group, the mean postoperative air-bone gap was 8.2 dB. No significant differences between the endoscopic and microscopic preoperative and postoperative values were reported. A total of eight complications (4.5%) were observed in the endoscopic cohort, although in the control group, no complication occurred. The mean surgical time was 51.9 minutes in the endoscopic group versus 48.2 minutes in the microscopic group (P > .05). No association between stapedotomy success and the increasing number of procedures was found. CONCLUSIONS Our article demonstrates that functional results from endoscopic stapes surgery are similar to those from microscopic stapes surgery in terms of both safety and efficacy. After gaining endoscopic experience, the surgical duration of stapes surgery will be adequate starting from the first cases. LEVEL OF EVIDENCE 4 Laryngoscope, 131:885-891, 2021.

Abstract
OBJECTIVES The aim of the present study was to examine some initial results and learning curves concerning subxiphoid single-port thymectomy (SSPT), thereby clarifying the safety of this surgical approach and describing the precautions for adopting it. METHODS From March 2011 to August 2019, a total of 203 patients underwent thymectomy for either anterior mediastinal tumours or myasthenia gravis at Fujita Health University Hospital. Of these 203 patients, 147 patients who had undergone SSPT were selected as participants for the present study. RESULTS Of the 147 cases, transition to a different approach was required in three (2.0%) cases: two (1.3%) cases transitioned to median sternotomy, whereas one (0.7%) case transitioned to the side chest trans-intercostal approach. The two cases that transitioned to median sternotomy were the second cases for different operators after they began performing this technique. There were six (4.0%) cases with complications and no deaths. The operation time cumulative summation learning curve analysis revealed that the curves descended from the 38th case. In the 83 cases handled by one surgeon, the learning curves descended from the 31st case. CONCLUSIONS SSPT is a safe modality with few complications and no associated cases of mortality reported. Operators are required to experience 31-38 cases until the operation time for SSPT was stabilized. Special care should be exercised to prevent vascular damage in the vicinity of the innominate veins during the early stages after SSPT introduction.

Abstract
Minimally invasive surgery has revolutionized the way surgeons perform colorectal surgery, and new technologies continually upend the way surgeons view and operate within the deep pelvis. Among other benefits, it is associated with decreased lengths of stay, wound and surgical site infections, pain scores, and has an overall lower complication rate vs. open surgery (1). Recently, however, the role of minimally invasive surgery has been called into question in the effective and safe treatment of rectal cancer. This manuscript will outline the history of minimally invasive rectal cancer surgery, examine evidence detailing its safety (compared with alternatives), and discuss important aspects of use, most notably the considerable learning curve required to achieve proficiency, the extent of its current use, and potential pitfalls. The current evidence suggests minimally invasive surgery is a very safe way to treat rectal cancer when performed by experienced and specialty trained surgeons.
