Holding the Knife on Perceptions of Surgery.

OBJECTIVE: Negative stereotypes associated with surgery by medical students are well documented in literature. Many cite long hours, poor work-life balance, pessimism, mean personalities, and cynicism as pervasive among surgeons and operating room culture. If allowed to persist, these negative perceptions can deter otherwise interested students from pursuing surgical subspecialties. DESIGN: Incorporation of peer-teaching in the third-year clerkship to not only illuminate the hidden curriculum in surgery but adequately prepare students to participate in the operating room is paramount to taking steps to improve student perception as well as success as clerkship students. SETTING: An academic medical center. PARTICIPANTS: Pre-clinical medical students. RESULTS: One-hundred and forty-three third year clerkship students were surveyed with pre- and postinstruments. Students who participated in these pre clerkship peer-teaching sessions reported significant improvements in their ability to identify surgical anatomy (p < 0.001), an increased confidence in answering questions from attendings about anatomy and function as well as in identifying anatomical abnormalities (all p < 0.001). Students also reported significantly improved perceptions about surgeons as teachers and their willingness to support students pursuing surgery. CONCLUSION: This study demonstrates that the incorporation of an immersive orientation prior to the start of the surgery clerkship has significantly positive impacts on the learning experience and confidence of medical students. Increased efforts should be made to introduce students to surgeons, surgical careers, and the operating room prior to the surgery clerkship, being sure to incorporate aspects of the hidden curriculum, to address the negative perceptions that continue to exist regarding surgical fields.

Intimidating Attendings: The Importance of Near-Peer Mentorship During Third-Year Surgical Clerkship.

INTRODUCTION: Near-peer instruction has grown in popularity in medical education; however, limited data exist to support its effectiveness. This study investigates the perceptions of near-peer style instruction in third-y medical students undergoing a surgical clinical clerkship. We hypothesized that near-peer instruction would provide a beneficial educational experience to third-y medical students during their surgical clinical clerkship. METHODS: The authors anonymously surveyed third-y medical students undergoing their clinical clerkship in surgery on their perception of the near-peer instruction and mentorship they received from fourth-y medical students at the beginning of the clerkship. Near-peer instruction included teaching suturing techniques, surgical procedures and anatomy, operating room literacy, and sharing anecdotal experiences. Surveys were distributed 24 h after receiving the formal instruction. RESULTS: A total of 85 students completed the survey (78% response rate). Students reported a similar or increase in value of learning from near-peer mentors compared to attending physicians (less valuable: 1.2%; just as valuable: 52.9%; more valuable: 45.9%). The majority of students indicated they would like to experience more near-peer style instruction in medical school as demonstrated in surgical clerkship training (absolutely no: 0%; probably not: 0%; on the fence: 4.7%; probably yes: 25.9%; absolutely yes: 69.4%). After experiencing near-peer instruction and mentoring, students were more interested in becoming near-peer mentors (less interested: 1.2%; just as interested: 29.4%; more interested: 69.4%). CONCLUSIONS: Students appreciate and desire near-peer instruction, seeing it as an effective learning method. Mentees undergoing near-peer style instruction have an increased interest in becoming near-peer mentors.

An Updated Systematic Review and Meta-Analysis of Tissue Oximetry Versus Conventional Methods for Postoperative Monitoring of Autologous Breast Reconstruction.

BACKGROUND: Tissue oximetry monitoring has shown superior outcomes to conventional monitoring methods for autologous breast reconstruction in retrospective studies with consecutive cohorts. A recent study used consecutive cohorts with tissue oximetry as the earlier cohort and found that tissue oximetry was nonsuperior. We hypothesize that improvement in microsurgical outcomes with institutional experience confounds the superiority of tissue oximetry demonstrated in prior studies. This study aimed to perform a systematic review and meta-analysis of the outcomes of tissue oximetry monitoring compared with conventional monitoring. METHODS: Relevant studies were found using PubMed, Embase, and Web of Science searches for keywords such as near-infrared spectroscopy or tissue oximetry and microsurgery. Studies included compared tissue oximetry and conventional monitoring in autologous breast reconstruction patients. Studies were excluded if they did not contain a comparison group. Random-effective models were used to analyze early returns to the operating room, the total number of partial or complete flap loss, and late fat necrosis. RESULTS: Six hundred sixty-nine studies were identified; 3 retrospective cohort studies met the inclusion criteria. A total of 1644 flaps were in the tissue oximetry cohort, and 1387 flaps were in the control cohort. One study contained tissue oximetry as the former cohort; 2 had tissue oximetry as the latter. Neither technique was superior for any measured outcomes. The estimated mean differences between tissue oximetry and conventional monitoring method were early returns, -0.06 (95% confidence interval [CI], -0.52 to 0.410; P = 0.82); partial flap loss, -0.04 (95% CI, -0.86 to 0.79; P = 0.93); complete flap loss, -1.29 (95% CI, -3.45 to 0.87; P = 0.24); and late fat necrosis -0.02 (95% CI, -0.42 to, 0.39; P = 0.94). CONCLUSIONS: In a systematic review and meta-analysis of mixed timeline retrospective cohort studies, tissue oximetry does not provide superior patient outcomes and shifts our current understanding of postoperative breast reconstruction monitoring. Prospective studies and randomized trials comparing monitoring methods need to be included in the existing literature.

Oncoplastic Breast Reconstruction for Large Pediatric Breast Tumors: A Case Series.

ABSTRACT: Large breast fibroadenomas in pediatric females may cause discomfort, asymmetry, and psychological stress, and patients may elect for surgical excision. There are no criteria for reconstruction after the excision of these masses, and the research is limited in describing oncoplastic techniques in pediatric fibroadenoma excision. Nononcoplastic techniques, such as mastectomy with implant or flap reconstruction, have been used for pediatric fibroadenoma excision reconstruction. Oncoplastic techniques using Wise pattern or circumareolar incisions have shown to have efficacious outcomes. In addition, pediatric females undergoing breast surgery risk long-term complications such as continued breast asymmetry due to further breast growth, nipple and breast hypoesthesia, and future breastfeeding difficulty. This case series describes the oncoplastic techniques used for large benign mass excision and reconstruction of 3 pediatric females. A Wise pattern technique was used for all 3 patients, and 2 underwent a free-nipple graft. Oncoplastic techniques for pediatric breast mass excision provide satisfactory aesthetic outcomes with minimal surgical morbidity. Further research assessing the long-term effects of pediatric breast mass excision and reconstruction would be beneficial.

Autologous Breast Reconstruction after Massive Weight Loss: Understanding Risks in a Growing Population.

BACKGROUND: Massive weight loss (MWL) may have suboptimal effects on tissues used for autologous reconstruction. With the rising rates of obesity and bariatric surgery, more patients who have experienced MWL will be presenting for breast reconstruction. The authors hypothesize that autologous breast reconstruction in patients with a history of MWL will have more complications and require more revisions compared with reconstruction in patients without a history of MWL. METHODS: A retrospective review was performed on patients who underwent autologous breast reconstruction by five microsurgeons at an academic institution from 2009 through 2020. Patients with a history of bariatric surgery or greater than 50-pound weight loss were identified and compared with patients who had not experienced MWL. Analysis compared demographics, operative details, complications, revision rates, and BREAST-Q scores. RESULTS: Of 916 patients who underwent 1465 flaps, 39 patients with MWL (4.3%) underwent 68 flaps (4.6%), and 877 patients without MWL underwent 1397 flaps. MWL patients were more likely to require blood transfusions postoperatively ( P = 0.005); experienced more surgical-site infections ( P = 0.02), wound-healing complications of flap ( P = 0.007) and donor sites ( P = 0.03), and late partial flap losses ( P = 0.03); and required more revisional surgery for flap ( P = 0.009) and donor sites ( P = 0.01). BREAST-Q scores were not statistically different for satisfaction with breasts or surgeon but were lower in MWL patients for psychosocial ( P = 0.01) and sexual well-being ( P = 0.04). CONCLUSIONS: Reconstructive surgeons should expect increased postoperative complications when performing autologous breast reconstruction in patients who have experienced MWL. These patients should be counseled on the possibility of an increased risk of postoperative complications and need for revisional surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

A Paradigm Shift: Outcomes of Early Autologous Breast Reconstruction after Radiation Therapy.

BACKGROUND: Radiation creates significant challenges for breast reconstruction. There is no consensus regarding optimal timing for autologous reconstruction following radiation. This study explores clearly defined, shorter time intervals between completion of radiation and reconstruction than previously reported. METHODS: A retrospective review was performed on patients who underwent autologous reconstruction by five microsurgeons at an academic institution from 2009 to 2020. Cohorts were selected by time elapsed between radiation and autologous reconstruction including <3 months, 3 to 6 months, 6 to 9 months, 9 to 12 months, 12 to 24 months, and >24 months. Analysis compared baseline characteristics, operative details, complications, revision rates, and BREAST-Q scores. Analysis of variance was used for continuous variables and chi-square for discrete variables. RESULTS: In total, 462 radiated patients underwent 717 flaps. There were 69 patients at <3 months (14.9%), 97 at 3 to 6 months (21%), 64 at 6 to 9 months (13.9%), 36 at 9 to 12 months (7.8%), 73 at 12 to 24 months (15.8%), and 123 at >24 months (26.6%). Age, time from mastectomy, and failure of primary reconstruction were higher at >24 months (p < 0.001). There was no difference between cohorts in intraoperative complications in radiated or nonradiated breasts. There was no difference in acute and late postoperative complications between cohorts. Wound-healing complications in radiated sides were lowest at <3 months and 3 to 6 months (5/69 [7.3%] and 11/97 [11.3%], respectively) compared with other groups (18.8-22.2%) but did not reach significance (p = 0.11). More fat graft revisions occurred at <3 months (p = 0.003). CONCLUSION: Reconstruction can be safely performed within 3 months after radiation without increases in intraoperative, acute, or late reconstructive complications.

Comparing tissue oximetry to doppler monitoring in 1367 consecutive breast free flaps.

BACKGROUND: Retrospective studies evaluating tissue oximetry in a more recent cohort have shown superiority in flap outcomes. This study compares the use of tissue oximetry in a historical cohort to clinical observation and handheld doppler in a more recent cohort. We hypothesize that there is no benefit to using tissue oximetry. METHODS: A retrospective review was performed on patients who underwent abdominal-based autologous breast reconstruction by five microsurgeons at an academic institution from 2009 to 2020. Method of postoperative flap monitoring was determined then operative details and complications were analyzed. RESULTS: 1367 flaps were reviewed; 740 flaps in 460 patients were monitored with clinical observation and tissue oximetry, and 627 flaps in 391 patients were monitored with clinical observation and handheld doppler. There were no statistical differences in ischemic (p = .59) or congestive complications (p = .41), flap salvage rates when exploring for venous or arterial compromise (p = .52), or early flap loss (p = .56). Although not significant, acute flap-related return to the operating room was lower in the doppler group (4.6%) compared to the oximetry group (6.1%; p = .22). Flaps monitored with tissue oximetry had a statistical increase in length of stay (4.8 ± 1.4 days vs. 3.8 ± 1.6 days; p ≤ .001). The rates of late partial flap loss and fat necrosis were significantly higher in the oximetry group (2.6%, 19/740 vs. 0.3%, 2/740; p = .04) and (18.2%, 135/740 vs. 13.6%, 85/627; p = .02), respectively. CONCLUSIONS: There is no statistical benefit to the use of tissue oximetry compared to handheld doppler in flap monitoring with regards to flap outcomes.

Closed-Incision Negative Pressure Therapy Prevents Major Abdominal Donor-Site Complications in Autologous Breast Reconstruction.

BACKGROUND: Outcomes in autologous breast reconstruction continue to improve with refinements in microsurgical techniques; however, donor-site morbidity remains a concern. Closed-incision negative pressure therapy (ciNPT) has been shown to reduce wound complications. Limited evaluation in abdominal donor sites has shown promising results. We hypothesize that ciNPT will reduce abdominal donor-site complications. METHODS: A retrospective chart review was performed of patients who underwent abdominally based autologous free tissue transfer for breast reconstruction by 4 microsurgeons at an academic institution from 2015 to 2020. The application of a commercial ciNPT for donor-site management was at the discretion of the operating surgeon. Demographics, operative details, and management of donor-site complications were analyzed. RESULTS: Four hundred thirty-three patients underwent autologous breast reconstruction; 212 abdominal donor sites were managed with ciNPT and 219 with standard dressings. Demographics were statistically similar between groups. Abdominal wound healing complications were noted in 30.2% of ciNPT patients (64/212) and 22.8% of control patients (50/219, P = 0.08); however, overall wound complications were attributed to obesity on multivariable analysis. Closed-incision negative pressure therapy significantly decreased complications requiring reoperation (ciNPT 6.2%, 4/64; control 26.5%, 13/51; P = 0.004). There were no significant differences in surgical site infection rates (P = 0.73) and rates of abdominal scar revisions (ciNPT 11.8%, 25/212; control 9.1%, 20/219; P = 0.37). CONCLUSIONS: Use of ciNPT in abdominal donor-site management significantly decreases the incidence of delayed wound healing requiring surgical intervention, with one major wound healing complication prevented for every 6 donor sites managed with ciNPT.

Analysis of Research Productivity and Assessment of Geographical Region in the General Surgery Match: How Much is Enough?

OBJECTIVES: The number of publications of prospective surgical residents has steadily increased over the past decade as the emphasis on research output has become paramount. However, the reported data from the National Resident Matching Program (NRMP) does not discriminate amongst impact, author position, and region of matched residents. This study aimed to evaluate categorical general surgery postgraduate year 1 (PGY-1) residents' research productivity by programs' research impact and region of the United States and support the need for additional public data on research metrics of accepted applicants. We hypothesize that residents accepted to top quartile schools will have more total and first author publications and higher h-index compared to residents in the other quartiles, and research metrics would not differ amongst the regions. DESIGN: The Doximity Residency Navigator was used to sort general surgery programs based on research output, which was determined by the average h-index of residents. All 2021 matriculating PGY-1 categorical residents from the top two programs from each region and quartile that met study criteria were included in the analysis. Web of Science (WoS) citation database was used to collect prior to residency and current total publications, and the first, last, and corresponding author positions of these publications. Residents' h-index and various research metrics reported by WoS were recorded. Descriptive statistics were used to examine the association between quartile and region. SETTING: Categorical general surgery residency programs throughout the United States. PARTICIPANTS: Categorical PGY-1 general surgery residents. RESULTS: The median total number of publications prior to residency was 1 (IQR = 0-5). The median total number of first-author publications prior to residency was 0 (IQR = 0-1), and the current h-index was 0 (IQR = 0-2). The top quartile had more total and first author publications prior to residency, while the other quartiles had similar metrics. Each region had similar total publications and h-index. CONCLUSIONS: Research output is significant for applicants applying to top-quartile research programs compared to the other 3 quartiles and is relatively similar throughout all regions of the United States. Public data is limited to future applicants.

Epidermal Growth Factor Receptor Inhibitor Treatment Timing does not Impact Survival in Stage 4 Colon Cancer Treatment: A Retrospective Study.

Introduction: Colon cancer impacts the lives of Kansans and those across the United States. Epidermal growth factor receptor (EGFR) inhibitors, such as panitumumab and cetuximab, have gained popularity as first-line treatment for stage 4 colon cancer despite their toxicities and have been used by clinicians in later lines of therapy. EGFR inhibitors have been proven to be an efficacious first-line treatment for stage 4 colon cancer, but no study has investigated outcomes comparing EGFR inhibitors as first-line treatment to its use as second- or third-line treatment. This study investigated EGFR inhibitor therapy estimated overall survival when used as first-, second-, and third-line treatment for stage 4 colon cancer. Methods: A retrospective review was done for patients with stage 4 colon cancer who underwent EGFR inhibitor treatment at a large academic center from November 2007 to August 2021. The patients were stratified into five groups by the line in which they received the EGFR inhibitor treatment. A log-rank test was used to analyze the groups, and the median survival for each group was determined. Results: A total of 68 patients were reviewed; 18 received first-line, 23 received second-line, 18 received third-line, 6 received fourth-line, and 3 received sixth-line treatment with an EGFR inhibitor. Fourth- and sixth-line therapies were excluded due to small patient size. There was no significant difference in estimated survival time between any of the lines. Median survival of the therapies was found. Conclusions: There was no statistical difference in survival between the first-, second-, or third-line groups, which may provide justification for its use as a second- or third-line therapy.
