Assessing the experience in complex hepatopancreatobiliary surgery among graduating chief residents: is the operative experience enough?

A propensity score matching analysis: Impact of senior resident versus fellow participation on outcomes of complex surgical oncology

BACKGROUND

Teaching hospitals that train both general surgery residents and fellows in complex general surgical oncology have become more common. This study investigates whether participation of a senior resident versus a fellow has an impact on outcomes of patients undergoing complex cancer surgery.

METHODS

Patients who underwent esophagectomy, gastrectomy, hepatectomy, or pancreatectomy between 2007 and 2012 with assistance from a senior resident (post-graduate years 4-5) or a fellow (post-graduate years 6-8) were identified from the ACS NSQIP. Based on age, sex, body mass index, ASA classification, diagnosis of diabetes mellitus, and smoking status, propensity-scores were created for odds of undergoing the operation assisted by a fellow. Patients were matched 1:1 based on propensity score. Postoperative outcomes including risk of major complication were compared after matching.

RESULTS

In total, 6934 esophagectomies, 13,152 gastrectomies, 4927 hepatectomies, and 8040 pancreatectomies were performed with assistance of a senior resident or fellow. After matching, overall rates of major complications were equivalent across all four anatomic locations between cases performed with the participation of a senior resident versus a surgical fellow: esophagectomy (37.0%% vs 31.6%, p = 0.10), gastrectomy (22.6% vs 22.3%, p = 0.93), hepatectomy (15.8% v 16.0%, p = 0.91), and pancreatectomy (23.9% vs 25.2%, p = 0.48). Operative time was shorter for gastrectomy (212 vs. 232 min; p = 0.004) involving a resident compared to a fellow, but comparable for esophagectomy (330 vs. 336 min; p = 0.41), hepatectomy (217 vs. 219 min; p = 0.85), and pancreatectomy (320 vs. 330 min; p = 0.43).

CONCLUSIONS

Senior resident participation in complex cancer operations does not appear to negatively impact operative time or postoperative outcomes. Future research is needed to further assess this domain of surgical practice and education, particularly with regard to case selection and operative complexity.

Trends in pancreatic surgery experience in general surgery residency in the US, 1990–2021

BACKGROUND

We hypothesized a decline in resident pancreatic operative experience. The study assesses trends in that experience since 1990.

METHODS

Accreditation Council for Graduate Medical Education (ACGME) national case log data of general surgery residency graduates from 1990 to 2021 were reviewed. Collected and analyzed were the mean and median total number of pancreatic operations per resident, the mean number of specific case types performed, and the annual number of residency graduates. For selected procedures, the mean number of cases by resident role (Surgeon-Chief and Surgeon-Junior) was also analyzed.

RESULTS

Both the mean and median total number of resident pancreatic operations has declined since 2009 as have the mean number of several specific pancreatic case types, including resections. The annual number of residency graduates has significantly increased since 1990, and particularly since 2009.

CONCLUSIONS

Resident volume in pancreatic operations has significantly declined over the last decade.

Getting going: Incorporating ultrasound into an HPB practice

The incorporation of ultrasound into a hepatopancreatobiliary surgical practice is both exciting and potentially intimidating. Although it is relatively straightforward to obtain detailed intraoperative ultrasound training from a small variety of formal programs, didactic curriculum, and mentorship experiences, seamless integration of this new knowledge into a hepatopancreatobiliary practice can be more challenging than expected. Although this is particularly true when a graduate begins a new practice, it is also relevant when incorporating hepatopancreatobiliary ultrasound into a mature group practice environment. This review outlines knowing your environment, certification and competency, credentialing and privileging, transition to independent practice, and maintaining competence.

Finding the Balance: General Surgery Resident Versus Fellow Training and Exposure in Hepatobiliary and Pancreatic Surgery

BACKGROUND

Institutions training both General Surgery (GS) residents and Hepato-Pancreatico-Biliary (HPB) fellows must strive for adequate case volumes for each trainee cohort.

METHODS

Six academic years of graduating ACGME Residency and HPB Fellowship Council case logs (July 2011-June 2017) and institutional administrative faculty billing data were examined at a single high-volume center with a formal HPB Surgical Division with both GS Residency and HPB Surgery Fellowship trainees.

RESULTS

During the 6-year period, 7482 operations were performed by HPB faculty (5.5 total full-time equivalent (FTE)) and included 2419 major liver, 375 major biliary, and 1591 major pancreas cases. Residents/fellows performed 1102 (50%)/1101 (50%) of all major liver operations, 165 (49.7%)/163 (50.3%) major biliary operations, and 843 (59.2%)/581 (40.8%) major pancreas operations, with significantly different case mix of pancreas for resident versus fellow, p < 0.0001. The overall relative proportion of total HPB cases performed by residents versus fellows was 53%/47%, respectively, and this was stable over time, with no significant decrease in resident exposure/cases with dedicated HPB fellowship.

CONCLUSIONS

Our experience in training both GS residents and HPB fellows with a formal HPB Surgical Division suggests that a high volume HPB Division allows for more than adequate exposure for both groups of trainees.

Hepato-pancreato-biliary and transplant surgery experience among New Zealand general surgery trainees

BACKGROUND

Subspecialty surgery experience during general surgery training in Australasia is influenced by many factors, including duration of training, training location and the introduction of post-fellowship training programmes. Experience in hepato-pancreato-biliary (HPB) and transplant surgery is part of the general surgery curriculum, although trainee experience in these subspecialties has not been quantified in this region, which is relevant to post-fellowship training programmes. Therefore, the aim of this study was to quantify the HPB and transplant operative experience of New Zealand (NZ) general surgery trainees.

METHODS

Operative logbook data were analysed for all NZ trainees from 2013 to 2017, including procedures categorized as pancreatic, biliary, hepatic and transplant surgery only. The number of cases within each category was used to model the cumulative operative experience over a 5-year training programme.

RESULTS

During the study period, 118 trainees (303 trainee years) recorded 15 662 HPB and transplant procedures. Of these, 13 838 (88.4%) were cholecystectomies (mean cumulative experience 219.3 cases). Excluding cholecystectomy, trainees had a mean cumulative experience of 5.7 biliary, 7.5 pancreatic, 8.1 liver and 4.2 transplant procedures during their training. Transplant experience was predominantly access for peritoneal dialysis (228/260, 86.7%), with cumulative transplant experience otherwise reaching 0.47 procedures over 5 years.

CONCLUSION

Exposure to HPB and transplant surgery during general surgery training in NZ is limited beyond cholecystectomy. Additional exposure during post-fellowship training is likely required for general surgeons to practice in these subspecialties.

Where Has All the Complexity Gone? An Analysis of the Modern Surgical Resident Operative Experience

OBJECTIVES

The operative experience of today's general surgery (GS) residents are changing. The Surgical Council on Resident Education (SCORE) was founded to provide a standardized, competency-based curriculum. We set out to evaluate resident operative experience in core and advanced operations.

DESIGN

Accreditation Council for Graduate Medical Education (ACGME) national operative log reports from 2010 to 2018 were reviewed. Operative volume data for 344 operations were extracted and analyzed. Operations were designated as core, advanced, or undefined as listed by SCORE, and stratified as GS or subspecialty.

SETTING

National analysis utilizing ACGME operative log reports.

PARTICIPANTS

All graduating general surgery residents between 2010 and 2018.

RESULTS

A total of 10,118 residents completed GS training with an average of 1121.5 ± 29.3 total cases. Core operations comprised 80.5% of total volume while advanced comprised only 8.0%. The total core experience increased (+7.0 cases/year), while total advanced experience decreased (-1.4 cases/year) (p < 0.01 each). Compositional analysis among core operations revealed an increase in 9/13 GS domains and a decrease in 8/10 subspecialty domains (all p < 0.05).

CONCLUSIONS

There has been an increase in core operative experience with a concurrent decrease in advanced operative experience of graduating GS residents. These findings highlight the continued narrowing of the operative experience for trainees, with increasing focus on GS and less on subspecialty domains. Ongoing efforts to look beyond operative volume to ensure competency of graduates will prove beneficial.

General surgery chief residents' perspective on surgical education during the coronavirus disease 2019 (COVID-19) pandemic

Background

The coronavirus disease 2019 pandemic has negatively affected the training of general surgery chief residents during the last trimester of their residency. Our goal was to evaluate the educational concerns of graduating general surgery chief residents during the coronavirus disease 2019 pandemic.

Methods

An anonymous web-based survey was distributed between March 31 and April 7, 2020 to all current general surgery chief residents from 6 academic medical centers in Boston, Massachusetts. Interviews were also conducted with attending surgeons from participating institutions.

Results

A total of 24 of 39 general surgery chief residents participated in our survey (61.5% response rate). General surgery chief residents were most concerned about the potential delay in the date of board examinations, followed by not feeling adequately prepared for the board examinations and a possible delay in the graduation date. Whereas not having enough cases to feel ready for fellowship or job and not achieving a sufficient number of cases to meet the requirements for graduation were only moderately concerning to chief residents, attending surgeons stressed a greater importance on the loss of the operative experience as nearly all (93.3%) of them suggested a personalized approach for additional general surgery training during fellowship or job onboarding.

Conclusion

In addition to the dramatic impact on public health, the coronavirus disease 2019 outbreak has also caused unprecedented changes to surgical education. Therefore, creative interventions are needed to help general surgery chief residents successfully transition into the next phase of their surgical career.

Energy vessel sealant devices are associated with decreased risk of neck hematoma after thyroid surgery

Postoperative neck hematomas following thyroidectomy occur in up to 6.5% of cases. It is unclear whether the use of energy vessel sealant devices effects the rate of PNH. We hypothesized use of an EVSD to be associated with decreased risk of PNH in patients undergoing thyroidectomy. The 2016-2017 American College of Surgeons Thyroidectomy database was queried for patients undergoing thyroidectomy with and without EVSDs. A multivariable logistic regression analysis was performed to evaluate for risk of PNH. From 11,355 patients undergoing thyroidectomy, an EVSD was used for 7460 (65.7%) patients. Age distribution was similar between the two groups (52 vs. 53-years old, p = 0.467). Compared to patients without EVSD used, patients with EVSD used had higher rates of comorbid hypertension (40.6% vs. 34.8%, p < 0.001) and diabetes (14.2% vs. 11.5%, p < 0.001); however, a lower rate of PNH (1.4% vs. 2.4%, p < 0.001). After adjusting for known risk factors for PNH including age, prior neck surgery, and comorbidities, EVSD use was associated with a decreased risk of PNH (OR 0.453, 95% CI 0.330-0.620, p < 0.001). The strongest associated risk factors for PNH were hypertension (OR 1.823, 95% CI 1.283-2.591, p = 0.001) and toxic goiter (OR 1.837, 95% CI 1.144-2.949, p = 0.012). When compared to standard vessel ligation, EVSD use was associated with a lower risk of PNH in patients undergoing thyroidectomy. The strongest associated risk factor for PNH was toxic goiter. Future prospective research is needed to confirm these findings and if corroborated, then increased use of an EVSD should be employed.

Resident Operative Experience in Hepatopancreatobiliary Surgery: Exposing the Divide

BACKGROUND

The Accreditation Council for Graduate Medical Education (ACGME) requires an experience in hepatopancreatobiliary (HPB) surgery as part of general surgery residency training. The composition of this experience, however, is unclear. We set out to evaluate current trends in the HPB experience of US general surgery residents.

METHODS

National ACGME operative case logs from 1990 to 2016 were examined with a focus on the HPB operative domains. Time-trend analysis was performed using ANOVA and linear regression analysis.

RESULTS

Median biliary, liver, and pancreatic operative volumes increased by 30%, 33%, and 27% over the 27-year study period (all p < 0.05). Both core and advanced HPB cases increased, but the rate of increase for core was four times greater than that of advanced. However, when cholecystectomy was excluded, this trend reversed such that HPB core operations decreased by 11 cases over the study period. Further analysis demonstrated that laparoscopic cholecystectomy comprised 90% of all biliary cases and 77% of all HPB cases for graduates in 2016. Finally, operative volume variability-the difference in case numbers between high and low volume residents-increased by 16%, 21%, and 73% for the biliary, liver, and pancreatic domains, respectively (all p < 0.05).

CONCLUSIONS

Despite increases in overall HPB operative volume, the HPB experience is changing for today's surgical trainees. Moreover, the HPB experience is comprised largely of a single operation-the cholecystectomy. Awareness of these trends is important for surgical educators to facilitate adequate exposure to HPB surgery among general surgery residents.

Complex hepato-pancreato-biliary caseload during general surgery residency training: are we adequately training the next generation?

BACKGROUND

Information on procedure volume of graduating chief residents (GCRs) for hepato-pancreato-biliary(HPB) surgical procedures may inform assessments of resident training. This study sought to characterize trends in operative volumes over a 19-year period to define the degree to which general surgery residents gain exposure to HPB procedures during training.

METHODS

The ACGME was queried for all HPB operations performed by GCR between 2000-2018. Total procedures as well as means and fold change was calculated and reported for each year.

RESULTS

Between 2000-2018, the number of general surgery residency programs varied between 240 and 254. A total of 411,383 HPB procedures (36.2% liver, 42.8% pancreas, 21% complex biliary) were performed by 22,229 GCR. Each year of the study, GCR had similar mean number total procedures:liver 7.4, pancreas 8.7, and complex biliary 4.4. For liver procedures there was no difference in the fold change over time, however for pancreas there was an increase in the fold change from 2.25 to 3.25.

CONCLUSION

Most GCRs are graduating with a low number of HPB procedures and trends suggesting a decrease in the mean number of procedures per GCR and an increasing variability among residents.

Perioperative factors impacting intensive care outcomes following Whipple procedure: A retrospective study

Background and Aims

Whipple procedure is associated with perhaps the most perioperative morbidity and mortality amongst surgical procedures. Current data regarding their ICU profile and outcomes are lacking. Thus, in the present study, we aimed to determine perioperative factors affecting patient-centred outcomes following the Whipple procedure.

Methods

In a cohort of patients undergoing pylorus-sparing pancreaticoduodenectomies, we strove to determine perioperative variables that may impact outcomes. Unfavourable outcomes (composite of mortality, prolonged ICU stay of more than 14 days or ICU readmission) of patients who underwent the procedure were recorded and logistic regressions analysis of significant variables conducted.

Results

Around 68 patients recruited over a 20-month period which included 57 males (83.8%); mean age was 53.4(±11.2) with mean acute physiology and chronic health evaluation (APACHE) II score12.5 (±6.1). Nineteen patients remained intubated at the end of procedures (27.9%). Median ICU stay was 2 days (IQR 2-3). Unfavourable ICU outcomes were 14 in number (20.6%) and 2 (2.9%) hospital deaths occurred. Pulmonary complications occurred in 12 patients (17.7%) and non-pulmonary complications occurred in 41 patients (60.3%). In a multiple logistic regression analysis, the APACHE score 1.34 (1.09-1.64) and pulmonary complications 17.3 (2.1-145) were variables that were identified as predictors of unfavourable outcomes.

Conclusion

The APACHE II score may reliably predict adverse outcomes following Whipple procedure. Although non-pulmonary complications are common, pulmonary complications in these patients adversely impact patient outcomes.

Is resident assistance equivalent to fellows during hepatectomy?

OBJECTIVE

Hepatectomy is a complex operative procedure frequently performed at academic institutions with trainee participation. The aim of this study was to determine the effect of assistant's training level on outcomes following hepatectomy.

METHODS

A retrospective review of a prospective, single-institution ACS-NSQIP database was performed for patients that underwent hepatectomy (2013-2016). Patients were divided by trainee assistant level: hepatopancreatobiliary (HPB) fellow versus general surgery resident (PGY 4-5). Demographic, perioperative, and 30-day outcome variables were compared using Chi-Square/Fisher's exact, Mann-Whitney U test, and multivariable regression. Cases involving a senior-level general surgery resident or HPB fellow as first assistant were included (n = 352). Those with a second attending, junior-level resident, or no documented assistant were excluded (n = 39).

RESULTS

Patients undergoing hepatectomy with an HPB fellow as primary assistant had more frequent preoperative biliary stenting, longer operative time, and more concomitant procedures including biliary reconstruction, resulting in a higher rate of post-hepatectomy liver failure (PHLF) (15% vs. 8%, P = 0.044). However, trainee level did not impact PHLF on multivariable analysis (OR 0.60, 95% CI [0.29-1.25], P = 0.173). Fellows assisted with proportionally more major hepatectomies (45% vs. 31%; P = 0.010) and resections for hepatobiliary cancers (31% vs. 19%, P = 0.014). On stratified analysis of major and minor hepatectomies, outcomes were similar between trainee groups.

CONCLUSION

Fellows performed higher complexity cases with longer operative time. Despite these differences, outcomes were similar regardless of assistant training level. Resident and HPB fellow participation in operations requiring liver resection provide comparable quality of care.

Training in endocrine surgery

BACKGROUND/PURPOSE

In Europe, the Division of Endocrine Surgery (DES) determines the number of operations (thyroid, neck dissection, parathyroids, adrenals, neuroendocrine tumors of the gastro-entero-pancreatic tract (GEP-NETs)) to be required for the European Board of Surgery Qualification in (neck) endocrine surgery. However, it is the national surgical boards that determine how surgical training is delivered in their respective countries. There is a lack of knowledge on the current situation concerning the training of surgical residents and fellows with regard to (neck) endocrine surgery in Europe.

METHODS

A survey was sent out to all 28 current national delegates of the DES. One questionnaire was addressing the training of surgical residents while the other was addressing the training of fellows in endocrine surgery. Particular focus was put on the numbers of operations considered appropriate.

RESULTS

For most of the operations, the overall number as defined by national surgical boards matched quite well the views of the national delegates even though differences exist between countries. In addition, the current numbers required for the EBSQ exam are well within this range for thyroid and parathyroid procedures but below for neck dissections as well as operations on the adrenals and GEP-NETs.

CONCLUSIONS

Training in endocrine surgery should be performed in units that perform a minimum of 100 thyroid, 50 parathyroid, 15 adrenal, and/or 10 GEP-NET operations yearly. Fellows should be expected to have been the performing surgeon of a minimum of 50 thyroid operations, 10 (central or lateral) lymph node dissections, 15 parathyroid, 5 adrenal, and 5 GEP-NET operations.

National Trends in General Surgery Resident Exposure to Complex Oncology-Relevant Cases

OBJECTIVE

To evaluate trends in surgical resident exposure to complex oncologic procedures in order to determine whether additional fellowship training is necessary.

DESIGN

An observational study of national Accreditation Council for Graduate Medical Education case log statistical reports was conducted to determine the average number of cases for selected oncology-relevant procedures completed during training. Linear regression and Cusick trend tests were used to assess temporal trends with the null hypothesis assuming an estimated slope of zero. Instrumental variable estimation was used to study the effect of duty-hour restrictions on oncologic cases per year.

SETTING

United States general surgery residency training programs.

PARTICIPANTS

Graduating surgical residents completing their training between 2000 and 2016.

RESULTS

Across the study interval, mean case volume was 950.6 ± 29.7 (standard deviation) cases with 38.9 ± 3.1 complex oncologic cases per graduating resident. Decreasing trends were noted for average exposure to lymphadenectomies (-7.8 cases/decade; 95% confidence interval [CI] -8.8 to -6.8) and low rectal procedures (-0.9 cases/decade; 95% CI -1.2 to -0.6). There was no clinically important change in complex soft-tissue resections and foregut cases. A significant increase was seen in number of hepatopancreaticobiliary procedures (+3.9 cases/decade; 95% CI 3.1-4.7). Using instrumental variable estimation, there was a modest decline in cancer-relevant cases by 5.0 cases/decade (95% CI 4.5-5.6), while there was an increase in 38.5 total cases/decade (95% CI 10.4-66.7) associated with duty-hour restrictions.

CONCLUSIONS

Case numbers for several complex oncologic procedures remain low, justifying a need for further fellowship training depending on individual resident experience.

Fellows' perspective of HPB training programs in North America: results of a survey

BACKGROUND

Sixteen hepatopancreatobiliary fellowship programs in North America are accredited by the Fellowship Council. This study aims to assess fellows' perceptions of their training program.

METHODS

A multiple-choice questionnaire was sent to 35 fellows to assess how they perceived their training: academics, research, operative experiences, autonomy, mentorship, program quality and weaknesses. The survey was developed using the SurveyMonkey^® tool.

RESULTS

Twenty-four of 35 fellows completed the survey. Sixteen fellows reported structured didactics; 10 reported mandatory research. As to operative experiences; 9 fellows reported exposure to minimally-invasive liver surgery; 5 reported exposure to robotics. Fourteen fellows reported using ablation; 5 reported using ablation laparoscopically; 8 reported using mostly radiofrequency ablation; 1 reported using irreversible electroporation. Eighteen fellows reported excellent training; 20 reported mentorship; 19 reported operative autonomy. Limited exposure to medical oncology/multidisciplinary care, portal hypertension surgery, and robotics surgery were perceived as program weaknesses by 7, 9, and 7 fellows, respectively.

CONCLUSION

Most fellows ranked their program quality and academic content as excellent, but they perceived a need for more exposure to medical oncology, portal hypertension surgery, and minimally-invasive surgery, with an emphasis on robotics. Fellowship training may need to integrate fellows' desires for enhanced proficiency in these clinical areas.

Robotic Pancreatoduodenectomy Biotissue Curriculum has Validity and Improves Technical Performance for Surgical Oncology Fellows

OBJECTIVE

Obtaining the proficiency on the robotic platform necessary to safely perform a robotic pancreatoduodenectomy is particularly challenging. We hypothesize that by instituting a proficiency-based robotic training curriculum we can enhance novice surgeons' skills outside of the operating room, leading to a shorter learning curve.

DESIGN

A biotissue curriculum was designed consisting of sewing artificial organs to simulate a hepaticojejunostomy (HJ), gastrojejunostomy (GJ), and pancreaticojejunostomy (PJ). Three master robotic surgeons performed each biotissue anastomosis to assess validity. Using video review, trainee performance on biotissue drills was evaluated for time, errors and objective structured assessment of technical skills (OSATS) by 2 blinded graders.

SETTING

This study is conducted at the University of Pittsburgh Medical Center (Pittsburgh, PA), a tertiary care academic teaching hospital.

PARTICIPANTS

In total, 14 surgical oncology fellows completed the biotissue curriculum.

RESULTS

Fourteen fellows performed 196 anastomotic drills during the first year: 66 (HJ), 64 (GJ), and 66 (PJ). The fellows' performances were analyzed as a group by attempt. The attendings' first attempt outperformed the fellows' first attempt in all metrics for every drill (all p < 0.05). More than 5 analyzed attempts of the HJ, there was improvement in time, errors, and OSATS (all p < 0.01); however, no metric reached attending performance. For the GJ, time, errors, and OSATS all improved more than 5 attempts (all p < 0.01), whereas only errors and OSATS reached proficiency. For the PJ, errors and OSATS both improved over attempts (p < 0.01) and reached proficiency; however, time did not statistically improve nor reach proficiency. The graders scoring correlated for errors and OSATS (p < 0.0001).

CONCLUSION

A pancreatoduodenectomy biotissue curriculum has face and construct validity. The curriculum is feasible and improves errors and technical performance. Time is the most difficult technical parameter to improve. This curriculum is a valid tool for teaching robotic pancreatoduodenectomies with established milestones for reaching optimum performance.

Resident and Attending Perceptions of Resident Involvement: An Analysis of ACGME Reporting Guidelines

OBJECTIVE

For general surgery residents (Residents) to log an operation, the ACGME requires "significant involvement" in diagnosis (DX), operation selection (SEL), operation (OPR), preoperative (PRE), and postoperative (POC) care. We compared how residents and attending surgeons (Attendings) perceived residents' role in each of these core requirements.

DESIGN

Residents and attendings completed surveys postoperatively regarding responsibility for each core requirement on a 5-point Likert scale from "Completely Attending" to "Completely Resident." Significance was determined using Chi-square analysis (p < 0.05) and degree of agreement was calculated using Spearman's rank correlation (r_s).

SETTING

Boston Medical Center, Boston, MA (tertiary institution).

RESULTS

A total of 302 paired surveys were analyzed. Residents more often performed a significant portion of the later stages of care (DX = 27%, PRE = 29%, SEL = 27%, OPR = 87%, and POC = 84%). Residents completed the majority of each requirement more frequently in operations performed in the acute setting compared to elective operations: DX (70% vs 8%, p < 0.01), PRE (74% vs 10%, p < 0.01), SEL (65% vs 11%, p < 0.01), OPR (100% vs 89%, p = 0.02), POC (100% vs 77%, p < 0.01). Resident participation was inversely related to operational complexity for DX (p < 0.01), PRE (p < 0.01), SEL (p < 0.01), and OPR (p = 0.01). Resident involvement in OPR increased at the end of the academic year (p = 0.05) and when working with junior attendings (<5 years in practice) (p = 0.01). Interpair agreement was greatest for DX (r_s = 0.70) and lowest for POC (r_s = 0.35). When residents and attendings did not agree in their answers, residents generally overstated their contribution to the DX (68%), PRE (58%), and SEL (64%) but understated their contribution in OPR (63%) and POC (62%).

CONCLUSIONS

Residents and attendings demonstrated reliable agreement for most core requirements, but residents were often unable to be involved in all 5 core requirements. Resident involvement was weighted toward later stages of patient care, yet residents often underestimated their contributions. Operational acuity, complexity, and attending experience correlated with resident operative involvement.

The influence of fellowship training on the practice of pancreatoduodenectomy

BACKGROUND

There has been a proliferation of gastrointestinal surgical fellowships; however, little is known regarding their association with surgical volume and management approaches.

METHODS

Surveys were distributed to members of GI surgical societies. Responses were evaluated to define relationships between fellowship training and surgical practice with pancreatoduodenectomy (PD).

RESULTS

Surveys were completed by 889 surgeons, 84.1% of whom had completed fellowship training. Fellowship completion was associated with a primarily HPB or surgical oncology-focused practice (p < 0.001), and greater median annual PD volume (p = 0.030). Transplant and HPB fellowship-trained respondents were more likely to have high-volume (≥20) annual practice (p = 0.005 and 0.029, respectively). Regarding putative fistula mitigation strategies, HPB-trained surgeons were more likely to use stents, biologic sealants, and autologous tissue patches (p = 0.007, <0.001 and 0.001, respectively). Surgical oncology trainees reported greater autologous patch use (p = 0.003). HPB fellowship-trained surgeons were less likely to routinely use intraperitoneal drainage (p = 0.036) but more likely to utilize early (POD ≤ 3) drain amylase values to guide removal (p < 0.001). Finally, HPB fellowship-trained surgeons were more likely to use the Fistula Risk Score in their practice (29 vs. 21%, p = 0.008).

CONCLUSION

Fellowship training correlated with significant differences in surgeon experience, operative approach, and use of available fistula mitigation strategies for PD.

Perception of training in hepatopancreatobiliary surgery among general surgery residents in the Americas

BACKGROUND

Hepatopancreatobiliary (HPB) surgery experience during residency in the Americas is limited. Residents interested in HPB surgery have different options available for further training. This study evaluated training in HPB surgery received during general surgery (GS) residency, and sought to determine the perception of fellowship training in HPB surgery.

METHODS

An anonymous survey was distributed to all 259 GS residency programs in the United States. Questions evaluated demographics, program structure, overall training & HPB experience in particular during residency, plans for fellowship training and understanding of training in HPB surgery.

RESULTS

Of the 340 respondents, 162 (48%) were from university programs, 145 (43%) from community hospitals and 48 (14%) from independent medical centers. 117 (34%) were residents in postgraduate year 4 or 5 (PGY4/PGY5). 275 (81%) respondents were planning to pursue fellowship training after finishing residency. Three quarters of all respondents did not feel comfortable about performing liver, biliary and pancreatic procedures. Fellowships accredited by the Americas Hepato-Pancreatico-Biliary Association (AHPBA) are the most common pathway considered by residents for HPB training.

CONCLUSIONS

GS residents are not comfortable in considering performing complex HPB cases on completion of residency training. GS residents consider AHPBA accredited fellowships to be more suitable for advanced training in HPB surgery.

Training in hepato-pancreato-biliary surgery during residency: past, present and future perspectives

The paradigm introduced by William Halsted for surgical residency training has been considered the most appropriate educational system to acquire the knowledge and surgical skills required to become a competent general surgeon. Hepato-pancreato-biliary (HPB) surgery is considered an important part of general surgery training because of its high prevalence and complexity. Nowadays, we are faced with a worldwide shortage of general surgeons candidates, restrictive working hours and less surgical exposure, situations that can undermine the objectives of training in HPB surgery during residency. Moreover, new generations of resident graduates are concerned about their lack of preparedness for independence. We cannot escape from this reality and therefore it justifies a reflection in our HPB surgical world community.

Qualities and characteristics of successfully matched North American HPB surgery fellowship candidates

BACKGROUND

Hepato-pancreato-biliary (HPB) fellowships in North America are difficult to secure with an acceptance rate of 1 in 3 applicants. Desirable characteristics in an HPB surgery applicant have not been previously reported. This study examines the perceptions of trainees and HPB program directors with regards to positive attributes in applicants for HPB fellowships.

METHODS

Parallel surveys were distributed by email with a web-link to current and recent HPB fellows in North America (from the past 5 years) with questions addressing the following domains: surgical training, research experience, and mentorship. A similar survey was distributed to HPB fellowship program directors in North America requesting their opinion as to the importance of these characteristics in potential applicants.

RESULTS

32 of 60 of surveyed fellows and 21 of 38 of surveyed program directors responded between November 2014-February 2015. Fellows overall came from fairly diverse backgrounds (13/32 were overseas medical graduates) about one third of respondents having had some prior research experience. Program directors gave priority to the applicant's interview, curriculum vitae, and their recommendation letters (in order of importance). Both the surveyed fellows and program directors felt that the characteristics most important in a successful HPB fellowship candidate include interpersonal skills, perceived operative skills, and perceived fund of knowledge.

CONCLUSION

Results of this survey provide useful and practical information for trainees considering applying to an HPB fellowship program.

Correlation between experience targets and competence for general surgery certification

Background

Working time restrictions and public expectation have stimulated competence-based assessment in surgery. Nevertheless, certification of completion of training, and board accreditation across the developed world, still rely on experiential models based on indicative numbers as markers of operative competence. This study assessed the correlation between trainer assessment of competence and completion of indicative numbers.

Methods

Analysis of UK Intercollegiate Surgical Curriculum Programme portfolios of general surgical trainees in a single Local Education and Training Board allowed comparison of Procedure Based Assessment (PBA) scores (level of competence) for cholecystectomy, segmental colectomy and Hartmann's procedure with operative numbers.

Results

Among 121 trainees, there was a positive correlation between operative numbers and 1058 PBA scores for cholecystectomy (rs = 0·532, P &lt; 0·001), segmental colectomy (rs = 0·552, P &lt; 0·001) and Hartmann's procedure (rs= 0·663, P &lt; 0·001). Of those who completed the indicative numbers defined for each procedure to achieve certification of completion of training, only eight of 30 performing cholecystectomy, eight of 52 undertaking segmental colectomy and seven of 36 performing Hartmann's procedure had achieved three PBAs at the level considered to represent independent operating (level 4). More than half of all assessments (259 of 428, 60·5 per cent; 85 of 132 cholecystectomy, 140 of 217 colectomy and 34 of 79 Hartmann's) performed after trainees had completed their indicative numbers were scored below level 4.

Conclusion

A minimum number of index procedures did not reflect competence in a significant proportion of trainees. A more reliable tool is required for certification.

Training and practice of the next generation HPB surgeon: analysis of the 2014 AHPBA residents' and fellows' symposium survey

BACKGROUND

Hepato-pancreato-biliary (HPB) surgery is a complex subspecialty drawing from varied training pools, and the need for competency is rapidly growing. However, no board certification process or standardized training metrics in HPB surgery exist in the Americas. This study aims to assess the attitudes of current trainees and HPB surgeons regarding the state of training, surgical practice and the HPB surgical job market in the Americas.

STUDY DESIGN

A 20-question survey was distributed to members of Americas Hepato-Pancreato-Biliary Association (AHPBA) with a valid e-mail address who attended the 2014 AHPBA. Descriptive statistics were generated for both the aggregate survey responses and by training category.

RESULTS

There were 176 responses with evenly distributed training tracks; surgical oncology (44, 28%), transplant (39, 24.8%) and HPB (38, 24.2%). The remaining tracks were HPB/Complex gastrointestinal (GI) and HPB/minimally invasive surgery (MIS) (29, 16% and 7, 4%). 51.2% of respondents thought a dedicated HPB surgery fellowship would be the best way to train HPB surgeons, and 68.1% felt the optimal training period would be a 2-year clinical fellowship with research opportunities. This corresponded to the 67.5% of the practicing HPB surgeons who said they would prefer to attend an HPB fellowship for 2 years as well. Overall, most respondents indicated their ideal job description was clinical practice with the ability to engage in clinical and/or outcomes research (52.3%).

CONCLUSIONS

This survey has demonstrated that HPB surgery has many training routes and practice patterns in the Americas. It highlights the need for specialized HPB surgical training and career education. This survey shows that there are many ways to train in HPB. A 2-year HPB fellowship was felt to be the best way to train to prepare for a clinically active HPB practice with clinical and outcomes research focus.

Portosystemic Shunts: Stable Utilization and Improved Outcomes, Two Decades After the Transjugular Intrahepatic Portosystemic Shunt

PURPOSE

The aim of this study was to assess national trends in utilization, demographics, hospital characteristics, and outcomes of patients undergoing surgical or percutaneous portal decompression since the introduction of transjugular intrahepatic portosystemic shunts (TIPS).

METHODS

A retrospective analysis of patients undergoing surgical portal decompression and TIPS procedures was conducted using Medicare Physician/Supplier Procedure Summary Master Files from January 2003 through December 2013 and National (Nationwide) Inpatient Sample data from 1993, 2003, and 2012. Utilization rates normalized to the annual number of Medicare enrollees, estimated means, and 95% confidence intervals were calculated.

RESULTS

The Medicare total annual utilization rate per million for all portosystemic decompression procedures decreased by 6.5% during the study period, from 15.3 in 2003 to 14.3 in 2013. TIPS utilization increased by 19.4% (from 10.3 to 12.3 per million), whereas open surgical shunt utilization decreased by 60.0% (from 5.0 to 2.0 per million). TIPS procedures represented 86% of all procedures in 2013. From 1993 to 2012, mean age increased slightly (from 53.0 to 55.5 years, P < .05). The percentage of procedures performed at teaching hospitals increased, whereas in-hospital mortality and length of stay decreased by 42% (P < .05) and 20% (P < .05), respectively. Of factors evaluated, the performance of procedures on an elective basis was the most influential on in-hospital mortality (P < .01, all years studied) and length of stay (P < .0001, all years studied).

CONCLUSIONS

Approximately two decades after the introduction of TIPS, the utilization of all portal decompression procedures has remained relatively stable. The TIPS procedure represents the dominant portal decompression technique. In-hospital mortality and mean length of stay after decompression have decreased, partially because of the performance of procedures during elective admissions.

What to expect when you're expecting a hepatopancreatobiliary surgeon: self-reported experiences of HPB surgeons from different training pathways

BACKGROUND

Hepatopancreatobiliary (HPB) surgery fellowship training has multiple paths. Prospective trainees and employers must understand the differences between training pathways. This study examines self-reported fellowship experiences and current scope of practice across three pathways.

METHODS

An online survey was disseminated to 654 surgeons. These included active Americas Hepato-Pancreato-Biliary Association (AHPBA) members and recent graduates of HPB, transplant-HPB and HPB-heavy surgical oncology fellowships.

RESULTS

A total of 416 (64%) surgeons responded. Most respondents were male (89%) and most were practising in an academic setting (83%). 290 (70%) respondents underwent formal fellowship training. Although fellowship experiences varied, current practice was largely similar. Minimally invasive surgery (MIS) and ultrasound were the most commonly identified areas of training deficiencies and were, respectively, cited as such by 47% and 34% of HPB-, 49% and 50% of transplant-, and 52% and 25% of surgical oncology-trained respondents. Non-HPB cases performed in current practice included gastrointestinal (GI) and general surgery cases (56% and 49%, respectively) for HPB-trained respondents, transplant and general surgery cases (87% and 21%, respectively) for transplant-trained respondents, and GI surgery and non-HPB surgical oncology cases (70% and 28%, respectively) for surgical oncology-trained respondents.

CONCLUSIONS

Fellowship training in HPB surgery varies by training pathway. Training in MIS and ultrasound is deficient in each pathway. The ultimate scope of non-transplant HPB practice appears similar across training pathways. Thus, training pathway choice is best guided by the training experience desired and non-HPB components of anticipated practice.

The impact of resident involvement on surgical outcomes among patients undergoing hepatic and pancreatic resections

BACKGROUND

Resident participation during hepatic and pancreatic resections varies. The impact of resident participation on surgical outcomes in hepatic and pancreatic operations is poorly defined.

METHODS

We identified 25,511 patients undergoing a hepatic or pancreatic resection between 2006 and 2012 using the American College of Surgeons National Surgical Quality Improvement Program database. Multivariate regression models were constructed to determine any association between resident participation and surgical outcomes.

RESULTS

Pancreatic resections (n = 16,045; 62.9%) were more common than liver resections (n = 9,466; 37%). Residents participated in the majority of cases (n = 21,857; 86%), with most involvement at the senior level (postgraduate year ≥ 3, n = 21,147; 97%). Resident participation resulted in slightly longer mean operative times (hepatic, 9 minutes; pancreatic, 22 minutes; both P < .01). Need for perioperative transfusion, hospital duration of stay, and reoperation rates were unaffected by resident participation (all P > .05). Resident participation resulted in a higher risk of overall morbidity (odds ratio [OR], 1.14; 95% CI, 1.05-1.24; P = .001), but not major morbidity (OR, 1.05; 95% CI, 0.93-1.20; P = .40) after liver and pancreas resection. Resident participation resulted in lower odds of 30-day mortality after liver and pancreas resections (OR, 0.75; 95% CI, 0.60-0.94; P = .01).

CONCLUSION

Although resident participation resulted in slightly longer operative times and a modest increase in overall complications after liver and pancreatic resection, other metrics such as duration of stay, major morbidity, and mortality were unaffected. These data have important implications for educating patients regarding resident participation in these complex cases.

The current state of hepatopancreatobiliary fellowship experience in North America

AIM

The face of hepatopancreatobiliary (HPB) training has changed over the past decade. The growth of focused HPB fellowships, which are vetted with a rigorous accreditation process through the Fellowship Council (FC), has established them as an attractive mode of training in HPB surgery. This study looks at the volumes of HPB cases performed during these fellowships in North America.

METHODS

After approval by the FC research committee, data from all HPB fellowships that had 3 years worth of complete fellow case log data were tabulated and reported (n = 12). For 2-year fellowships, the fellow logs were tabulated at the completion of both years. Those programs that had transplant experience (n = 9) were reported.

RESULTS

Data for the current fellows' case numbers show that graduating fellows have a median of 26 biliary cases, 19 major liver cases (hemilivers), 28 other liver cases, 40 pancreaticoduodenectomies,18 distal pancreatectomies, and 9 other pancreas cases. The programs that provided transplantation experience had 10 cases for each fellow.

CONCLUSION

This study validates that FC-accredited HPB fellowships have a robust exposure to complex HPB surgery. Fellows completing these fellowships should be well versed in the management and surgical treatment of HPB patients.
