Exploring mentorship in surgery: An interview study on how people stick together.

OBJECTIVE: The objective is to explore the processes contributing to how and why mentors and mentees initiate, maintain and grow in their mentorship relationships in surgery. BACKGROUND: To explore the processes contributing to how and why mentors and mentees initiate, maintain and grow their mentorship relationships in surgery. Evidence suggests that mentorship has a positive impact on physicians' success. Consequently, mentorship programmes have been incorporated into many medicine environments, albeit with variable success. METHODS: We designed an interview-based study using a constructivist grounded theory approach to explore the dynamics of mentorship between junior and experienced surgeons. Recruited mentees were asked to nominate a senior surgeon they identified as a mentor. Both mentee and mentors were then interviewed separately. Transcripts were analysed using constant comparison to a create a final coding framework and to generate themes. RESULTS: We interviewed nine faculty mentors and 10 junior faculty mentees. Our analysis identified key themes describing how to initiate, maintain and grow a mentorship relationship. Mentorship starts with ensuring a 'good fit', persists through satisfying a reciprocal loop with timely communication and deepens the relationship through cycles of mutual investment, learning, and success. Participants also discussed how to navigate through tensions to avoid relationship breakdown, balancing formality and friendship, knowing when to transition a relationship to a new dynamic and finding areas of realistic contribution. CONCLUSIONS: We found that successful mentorship relationships are viewed as dynamic and thus require active investment and shared responsibility between mentees and mentors. Our results also emphasise the value of co-regulation in the relationship, where cycles of mutual investment can contribute to mutual learning and growth.

The incidence of iron deficiency anemia post-Roux-en-Y gastric bypass and sleeve gastrectomy: a systematic review.

SETTING: The physiological and anatomical changes that occur as a consequence of bariatric surgery result in macro- and micro-nutritional deficiencies, especially iron deficiency. The reported incidence of iron deficiency and associated anemia after bariatric surgery varies widely across studies. OBJECTIVES: The aim of this systematic review is to quantify the impact of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on the incidence of iron deficiency. METHODS: Databases including Ovid Medline, Ovid Embase, Helthstar, Scopus, Cochrane (CDSR), LILACS, and ClinicalKey were searched for original articles with additional snowballing search. Search terms included Obesity, nutrient deficiency, iron deficiency, iron deficiency anemia, bariatric surgery, Roux-en-Y gastric bypass, and sleeve gastrectomy. Original articles reporting the incidence of iron deficiency and anemia pre- and post-RYGB and SG from January 2000 to January 2015 with minimum 1-year follow-up were selected. Data extraction from selected studies was based on protocol-defined criteria. RESULTS: There were 1133 articles screened and 20 studies were included in the final analysis. The overall incidence of iron deficiency was 15.2% pre-operatively and 16.6% post-operatively. When analyzed by procedure, the incidence of iron deficiency was 12.9% pre-RYGB versus 24.5% post-RYGB and 36.6% pre-SG versus 12.4% post-SG. The incidence of iron deficiency-related anemia was 16.7% post-RYGB and 1.6% post-SG. Risk factors for iron deficiency were premenopausal females, duration of follow-up, and pre-operative iron deficiency. Prophylactic iron supplementation was reported in 16 studies and 2 studies provided therapeutic iron supplementation only for iron-deficient patients. Iron dosage varied from 7 to 80 mg daily across studies. CONCLUSION: Iron deficiency is frequent in people with obesity and may be exacerbated by bariatric surgery, especially RYGB. Further investigation is warranted to determine appropriate iron supplementation dosages following bariatric surgery. Careful nutritional surveillance is important, especially for premenopausal females and those with pre-existing iron deficiency.

Establishing meaningful benchmarks: the development of a formative feedback tool for advanced laparoscopic suturing.

BACKGROUND: Time and accuracy are commonly used metrics to assess laparoscopic skills in a simulated environment. However, they do not provide trainees with meaningful information about how to improve their skills. The objective of this study was to provide preliminary validity evidence for the creation a formative feedback tool (FFT) for advanced laparoscopic suturing skills. METHODS: Videotapes of senior surgical residents (PGY3-5; SRs) and minimally invasive surgeons (MIS) performing 3 advanced laparoscopic suturing tasks were analyzed: needle handling (NH), suturing under tension (UT), and continuous suturing (CS). A FFT was created based on a grounded theory analysis of interviews with MIS surgeons about the key technical aspects of each task. The FFT was used to assess the videotaped performances of SRs and MIS surgeons by two blinded independent raters. RESULTS: The FFT is composed of three parts: NH contains 10 items, UT 18, and CS 20. Each item was classified according to seven key surgical principles: depth perception, safety, bimanual dexterity, exposure, tissue handling, instrument manipulation, and forward planning. The videotaped performance of SR and MIS surgeons was graded on a 3-point Likert scale ("does well," "needs some improvement," and "does poorly") and scores were calculated as a sum of the points. ICCs for all three tasks were high (NH 0.90, UT 0.87, and CS 0.90). FFT score correlated strongly with combined time and accuracy measurements for UT (0.82, p < 0.01) and CS (0.81, p < 0.01), and moderately for NH (0.65, p < 0.01). MIS surgeons performed significantly better than SRs on UT (p = 0.02) and CS (p = 0.05), while scores on NH were similar (p = 0.57). CONCLUSIONS: A comprehensive tool for providing feedback about advanced laparoscopic suturing skills was developed. The FFT demonstrates evidence for validity as a measure of suturing skills and experience, and provides meaningful information to trainees about how to improve their skills and engage in more deliberate and efficient practice.

New models for advanced laparoscopic suturing: taking it to the next level.

BACKGROUND: Current simulations for laparoscopic suturing do not reflect the complexity of the skills required in the operating room. The purpose of this study was to develop three novel advanced suturing tasks with assessment metrics and to collect validity evidence for their measures of suturing skill. METHODS: We developed three tasks based on training gaps identified through a previous needs assessment: needle handling (NH), suturing under tension (UT), and continuous suturing (CS). Minimally invasive surgeons (MIS) and senior surgical residents (SR) completed these tasks and a questionnaire regarding their educational value. Performance was assessed by two raters based on time and accuracy. Validity was assessed by comparing performance according to the level of training and self-reported experience. The inter-rater reliability and internal consistency of the tasks were calculated. RESULTS: Thirty-one subjects (13 MIS, 18 SR) were enrolled in the study (median age 32; 77% male). Compared to the SR group, the MIS group had significantly greater scores on all tasks. While all MIS surgeons completed the three tasks within the allotted time, six (33%) residents could not complete at least one out of the three tasks. Laparoscopic suturing experience correlated positively with the scores of all tasks (NH 0.51, UT 0.70, CS 0.65. p < 0.01). Inter-rater reliability for all tasks was 0.99, and internal consistency was 0.80. The majority of participants agreed that the tasks were relevant to practice, helped improve technical competence, and adequately measured suturing ability. CONCLUSIONS: This study provides validity evidence for three novel advanced laparoscopic suturing tasks. Performance on all tasks correlated significantly with training level and self-reported experience. Integrating these tasks into educational curricula may help improve residents' suturing skills and better prepare residents for the operating room.

A Video-Based Assessment Tool to Measure Intraoperative Laparoscopic Suturing Using a Modified Script Concordance Methodology.

OBJECTIVES: Laparoscopic suturing (LS) is a challenging laparoscopic skill to teach. Its complexity and nuances are not modeled or measured in current simulation and assessment platforms.The script concordance test (SCT) is used to assess clinical reasoning.The purpose of this study is to provide evidence for validity of this novel SCT based online assessment for LS skills. DESIGN: We designed a video-based online SCT for LS using a cognitive task analysis and expert panelists.The CTA yielded 4 LS domains: needle handling (NH), tissue handling (TH), knot tying techniques (KT) and operative ergonomics (OE). Five-point scales with anchoring descriptors from -2 to +2 were used. Scoring was based on a modified SCT methodology. SETTING AND PARTICIPANTS: The test was administrated to 37 subjects (18 experts and 19 novices). There was no time limit given. A different expert group from the minimal invasive surgery (MIS) panelist were recruited. Experts were defined as surgeons and fellows with LS experience of >25 cases annually. Validity was assessed by comparing SCT scores of experienced and inexperienced surgeons. Cronbach's alpha was used to assess the internal consistency of the test. RESULTS: The survey started off with 47 questions in each of the following domains: 13 NH, 4 TH, 20 KT and 10 OE. Thirty-seven surgeons (18 experts and 19 inexperienced surgeons). Questions that demonstrated a large discrepancy among experts and panelists with a weighted score difference more than 40 were discarded (n = 20). One question was discarded because it received a 100% score from all participants. This yielded 26 remaining questions in the following domains: 8 NH, 2 TH, 11 KT and 5 OE. The test reliability level (Cronbach a) was 0.80. The mean score was 72 ± 9% and 63 ± 15% (p = 0.02) for experts and inexperienced surgeons, respectively. The mean time to complete the test was 21 minutes. CONCLUSION: This study provides validity evidence for a novel intraoperative LS assessment. The variability of responses between experts and panelists suggests that SCT may capture the clinical differences/surgeon preferences in performing LS intraoperatively.

Histopathological Patterns and Outcomes of Triple-Positive Versus Triple-Negative Breast Cancer: A Retrospective Study at a Tertiary Cancer Center.

Background One of the leading causes of cancer-related deaths in females under 45 years old is breast cancer (BC). The definition of triple-negative breast cancer (TNBC) is the lack of expression of estrogen receptors (ERs) as well as progesterone receptors (PRs) and Erb-B2 receptor tyrosine kinase 2 (HER2) gene amplification. Triple-positive breast cancer (TPBC), on the other hand, is defined as tumors expressing a high level of ER, PR, and HER2 receptors. This study aims to assess the phenotypes of TNBC and TPBC by comparing their individual clinical behavior patterns and prognosis throughout the course of the disease in a tertiary cancer center in the Kingdom of Saudi Arabia (KSA). Methods Our study is a retrospective study using electronic medical records (EMRs) to identify all female patients diagnosed with BC using the International Classification of Diseases-10 (ICD-10) codes (between C50 and C50.9). About 1209 cases with primary BC female patients were recognized based on histopathology reports. Further subclassification into TPBC and TNBC was performed. Statistical analysis was performed using Rv3.6.2 (R Studio, version 3.5.2, Boston, MA, USA). The descriptive data were presented as means and standard deviations (SD). Survival curves were approximated using the Kaplan-Meier method. The comparison between survival curves between both groups was achieved using the log-rank test. The multivariate model was constructed based on the identified predictors using univariate analysis. Results Univariate analysis of overall survival (OS) showed that mortality was higher in TNBC compared to TPBC (HR = 2.82, P-value <0.05). However, in a multivariate analysis, molecular subtypes did not show a significant effect on OS with a P-value of 0.94. We found that age at diagnosis has been associated with a 4% increase in mortality risk with a yearly rise in age. Conclusion In this limited retrospective cohort study, we found that TNBC may not be associated with a higher risk of death than TPBC. However, other factors, including age at diagnosis, surgical intervention, and lymphovascular invasion (LVI), have been observed to increase the risk of mortality. On the other hand, patients with TNBC were found to have a worse prognosis in terms of local recurrence. This information cannot be generalized to all patients with BC given the limitations of this study. Further, larger cohorts are needed to explore biological and treatment-related outcomes in patients with TNBC and TPBC.

What are the Training Gaps for Acquiring Laparoscopic Suturing Skills?

INTRODUCTION: Advanced laparoscopic suturing is considered a challenging skill to acquire. The aim of this study was to investigate the learning process for advanced laparoscopic suturing in the operating room to understand the obstacles trainees face when trying to master the skill. METHODS: A qualitative methodology using semistructured interviews and field observations was used. Data were analyzed using a Grounded Theory approach. Participants were general surgery residents and surgeons with advanced minimally invasive surgery (MIS) experience. RESULTS: Ten MIS surgeons across different institutions and 15 local general surgery residents were interviewed. The semistructured interviews and field observations of 9 advanced MIS operations (27h) yielded the following 6 themes around the acquisition of laparoscopic suturing skills for residents: complexity, training misalignment, variability of opportunities, inconsistency of techniques, lack of feedback, and differing expectations. CONCLUSION: There are several unmet training needs around laparoscopic suturing skills. Training for advanced laparoscopic skills requires more emphasis on coaching and the development of advanced models. This study heralded the need to incorporate advanced laparoscopic skills into the surgical simulation curriculum.

Perioperative feedback in surgical training: A systematic review.

BACKGROUND: Changes in surgical training have raised concerns about residents' operative exposure and preparedness for independent practice. One way of addressing this concern is by optimizing teaching and feedback in the operating room (OR). The objective of this study was to perform a systematic review on perioperative teaching and feedback. METHODS: A systematic literature search identified articles from 1994 to 2014 that addressed teaching, feedback, guidance, or debriefing in the perioperative period. Data was extracted according to ENTREQ guidelines, and a qualitative analysis was performed. RESULTS: Thematic analysis of the 26 included studies identified four major topics. Observation of teaching behaviors in the OR described current teaching practices. Identification of effective teaching strategies analyzed teaching behaviors, differentiating positive and negative teaching strategies. Perceptions of teaching behaviors described resident and attending satisfaction with teaching in the OR. Finally models for delivering structured feedback cited examples of feedback strategies and measured their effectiveness. CONCLUSIONS: This study provides an overview of perioperative teaching and feedback for surgical trainees and identifies a need for improved quality and quantity of structured feedback.
