Unplanned hospital readmission after cholecystectomy in adults with cerebral palsy.

BACKGROUND: Adults with cerebral palsy (CP) are a largely understudied, growing population with unique health care requirements. We sought to establish a deeper understanding of the surgical risk in adults with CP undergoing a common general surgical procedure: cholecystectomy. METHODS: Data were obtained from the State Inpatient Database developed for the Healthcare Cost and Utilization Project. Inclusion criteria included patients ≥ 18 years with CP and a primary ICD-9 procedure code indicating open or laparoscopic cholecystectomy. Demographics, procedure-related factors, and comorbid conditions were analyzed, and unplanned 30 and 90 day readmission rates calculated for each variable. Reasons for readmission based on ICD-9 diagnosis codes were grouped into relevant categories. Univariate analysis identified factors significantly associated with readmission rates. RESULTS: A total of 802 patients with CP met the inclusion criteria. Unplanned 30 and 90 day readmission rates after laparoscopic cholecystectomy were 11.4% and 18.1%, respectively. Average length of stay (LOS) after laparoscopic cholecystectomy was 7.1 days. After open cholecystectomy, 30 and 90 day readmission rates were 16.9% and 30.3% with an average LOS of 14.6 days. Infection was the most common cause for 30 and 90 day readmission. Factors associated with 30 day readmission included type of cholecystectomy, LOS, discharge to skilled nursing facility, and comorbid diabetes and malnutrition. Factors associated with 90 day readmission included type of cholecystectomy, LOS, discharge to skilled nursing facility, and comorbid heart failure, renal disease, epilepsy, and malnutrition. CONCLUSION: Unplanned readmission rates after open and laparoscopic cholecystectomy in adult patients with CP are much higher than previously demonstrated rates in the general population. These patients frequently suffer multiple comorbid conditions that significantly complicate their surgical care. As more and more of these patients live longer into adulthood, further study is warranted to grasp the perioperative risk of simple and complex surgical procedures.

Instilling Resiliency in Surgical Education: The Benefits of Longitudinal Medical Student Learning.

The longitudinal clerkship has been recognized as an innovative, unique model in medical education that demonstrates significantly higher student and preceptor satisfaction with comparable long-term outcomes like performance on standardized examinations. At the center of this model is the student-preceptor relationship, which promotes effective student-directed learning and personal and professional relationships with established faculty mentors. The University of California, San Francisco (UCSF) has two clerkships models: a traditional or "block" model consisting of 2-month sequential clinical rotations in seven core clerkships, and a longitudinal model that integrates parallel out-patient clinical experiences over the entire year with one-on-one faculty preceptors from each core discipline with focused 2-week intensive inpatient rotations. In the setting of the Covid-19 pandemic beginning in Spring of 2020, this arrangement allowed for a natural experiment to evaluate the resiliency of the respective models in the face of unprecedented disruptions in education and healthcare delivery. As described in this perspective, both clerkships required rapid pivots; however, students enrolled in the longitudinal clerkship were more likely to develop stronger relationships with surgical faculty and felt more prepared for making career choices. Medical school curricula may benefit from incorporating longitudinal components, as this model provided flexibility and fostered greater faculty-student mentorship in the setting of disruption to medical education.

Predictors and Outcomes of Paramedian Incisional Hernia After Anterior Spine Exposure.

BACKGROUND: Anterior exposures for lumbar spine surgery are increasingly common for treating various spinal pathologies. A retroperitoneal approach via a paramedian incision has grown rapidly in popularity, but little is known about the risk of incisional hernia development with this technique. We sought to assess the incidence of paramedian incisional hernia development and identify risk factors that are associated with occurrence. MATERIALS AND METHODS: We conducted a retrospective review of all patients who underwent anterior lumbar spine exposure by a paramedian approach between 2012 and 2017 at a single, tertiary medical center. The primary outcome was the development of postoperative paramedian incisional hernia. RESULTS: Of the 735 patients included in the study, 445 (60.5%) were women, and the mean (standard deviation) age of all patients was 60 y (12.4). Nearly all (97.4%) paramedian approaches were performed with a vascular surgeon present. Median follow-up time was 10 mo (interquartile range 3.5-19.9). Postoperative paramedian hernia developed in 20 patients (2.7%), of which 14 underwent repair. The mean (standard deviation) size of the hernia was 13.5 cm (5.5); 9 of 14 (64%) were repaired with synthetic mesh, whereas 3 of 14 (21%) required bowel resection. On multivariate analysis, risk factors associated with hernia development were male gender (0.045), higher American Society of Anesthesiologists class (0.039), history of abdominal surgery (P = 0.013), and postoperative intensive care unit admission (P = 0.02). CONCLUSIONS: A paramedian approach for anterior lumbar spine exposure resulted in a low rate of incisional hernia with minimal morbidity. Surgeons involved in these collaborative procedures should consider the risk factors that predispose patients to develop these hernias.

Upper Gastrointestinal Endoscopy in an Academic General Surgical Program: Implications for Acute Care Surgeons.

Background. Esophagogastroduodenoscopy (EGD) is an important tool in the evolving specialty of acute care surgery (ACS). Understanding the types of nonelective EGDs performed by ACS groups is important for the development of ACS programs and the training of future general surgeons. Methods. We conducted a retrospective review of all EGDs performed by ACS surgeons at a single urban academic center over a 5-year period (January 2013-December 2018). Results. A total of 495 EGDs were performed, of which 129 (26%) were urgent, nonelective procedures. Patients who underwent urgent EGD were younger than those who underwent elective procedures (median 55 vs 60 years, P = .03), had higher American Society of Anesthesiologists (ASA) classes (median ASA 3 vs 2, P = .0002), and longer hospital stays (median 5 days vs 0 days, P < .0001). The most common indications for urgent endoscopies were the management of leak, dysphagia, or stenosis in patients with a history of foregut surgery, followed by the management of esophageal perforation. The success rate of endoscopic therapy was high (median 88%, interquartile range (IQR) 78-89%). However, some patients required multiple interventions (median 1, IQR 1-3), and patients treated for leaks were less likely to be successfully treated with endoscopic therapy alone than patients treated for other indications (success rate 65% vs 88%, P = .003). Conclusions. Our experience suggests that EGD has an important role in current ACS practice and that endoscopic management is safe and effective in a range of urgent surgical scenarios. Future ACS surgeons should be facile with endoscopic techniques.

Safety and feasibility of sleeve gastrectomy in morbidly obese patients following liver transplantation.

BACKGROUND: Obesity, steroid-induced diabetes, hypercholesterolemia, and steatohepatitis can occur after liver transplantation and may respond to bariatric surgery. The safety and feasibility of bariatric surgery after liver transplantation is unknown. METHODS: Nine morbidly obese patients with prior liver transplants underwent sleeve gastrectomy in a pilot program. Sleeve gastrectomy was chosen over gastric banding to avoid foreign body implantation, and over gastric bypass to maintain endoscopic access to the biliary system and reduce surgical complexity. We reviewed patient demographics, operative details, 30-day complications, weight loss, postoperative hepatic and renal functions, and resolution of comorbidities. RESULTS: Sleeve gastrectomy was performed laparoscopically in eight patients and as an open procedure in one patient. The mean operative time was 165 min and mean postoperative length of stay was 5 days. Follow-up ranged from 3 to 36 months. In the first 30 days, there were three complications in three patients: mesh dehiscence after a synchronous incisional hernia repair, bile leak from the liver surface requiring laparoscopic drainage, and postoperative dysphagia that required reoperation. Calcineurin inhibitor levels and hepatic and renal functions remained stable. There were no episodes of graft rejection. At 3 months liver function tests remained stable. Excess weight loss averaged 55.5% at 6 months. CONCLUSION: Sleeve gastrectomy is technically feasible after liver transplantation and resulted in weight loss without adversely affecting graft function and immunosuppression. Early complications may be more frequent as a result of adhesions of the left upper quadrant. Late complications were rare.

Third year medical student knowledge gaps after a virtual surgical rotation.

INTRODUCTION: This study describes perceived knowledge gaps of third-year medical students after participating in a virtual surgical didactic rotation (EMLR) and shortened in-person surgery rotation during the COVID-19 Pandemic. METHODS: Open-ended and Likert questions were administered at the end of the virtual rotation and inperson-surgical rotation to medical students. Three blinded coders identified themes by semantic analysis. RESULTS: 82 students (51% of all MS3s) participated in the EMLR. Semantic analysis revealed gaps in perioperative management (Post-EMLR:18.4%, Post-Inpatient:26.5%), anatomy (Post-EMLR:8.2%, PostInpatient:26.5%). and surgical skills (Post-EMLR: 43.0%, Post-Inpatient: 44.1%). Students also described gaps related to OR etiquette (Post-EMLR: 12.2%, Post-Inpatient: 8.8%) and team dynamics/the hidden curriculum (Post- Inpatient:26.6%). There was a significant improvement in perceived confidence to perform inpatient tasks after completing the inpatient clinical experience (p ≤ 0.01). CONCLUSION: Virtual interactive didactics for cognitive skills development cannot replace a full clinical surgical experience for third-year medical students. Future curricula should address perceived gaps.

Bursting the Hidden Curriculum Bubble: A Surgical Near-Peer Mentorship Pilot Program for URM Medical Students.

The hidden curriculum of unspoken professional expectations negatively impacts medical student interest in surgery. Medical student mentorship and early surgical exposure have been shown to demystify the hidden curriculum. Although residents and faculty play a vital role, near-peer mentorship may aid in uncovering the hidden curriculum and promoting medical student interest in surgery, especially for those learners who are underrepresented in medicine. We developed and implemented a formalized near-peer mentorship program composed of quarterly small group Surgical Peer Teacher led lessons and one-on-one Surgical Support Team mentorship meetings covering surgical curriculum topics for medical students at an academic medical school. This structured near-peer mentorship model provides a mechanism to demystify surgical culture, increase early access to surgical mentorship, and develop mentorship skills amongst students. This program aims to uncover the surgical hidden curriculum to improve surgical career support and interest among medical students with less exposure and access to physician role models. This longitudinal mentorship model is student-run and can be easily adapted to enhance existing support models at medical schools. Future studies will evaluate utilization, impact on surgical specialty interest, and efficacy in demystifying the surgical hidden curriculum.

Surgery Clerkship Curriculum Changes at an Academic Institution during the COVID-19 Pandemic.

PROBLEM: The COVID-19 pandemic has suspended the surgery clinical clerkship for third-year medical students at numerous institutions across the world. As a result, educators and students have adapted rapidly. There is a paucity of precedents regarding urgent and brusque formal curricular changes for medical students enrolled in surgical clinical rotations. APPROACH: The University of California, San Francisco Department of Surgery created a surgically focused extended mastery learning rotation (EMLR). The surgery clerkship leadership designed a curriculum consisting of multiple learning strategies compatible with virtual learning environments. The primary aims of the newly developed EMLR were to help students consolidate their foundational science knowledge before their return to clinical medicine in an altered learning environment. The EMLR is currently underway, and further studies are necessary to evaluate its effectiveness.

"There Is a Lot of Change Afoot": A Qualitative Study of Faculty Adaptation to Elimination of Tiered Grades With Increased Emphasis on Feedback in Core Clerkships.

PURPOSE: Medical schools responding to challenges with fairness, equity, learning environments, and student wellness have reconsidered clerkship grades. This study used the Concerns-Based Adoption Model (CBAM) to explore how faculty responded to a change in the approach to assessment from focus on grades toward focus on feedback. METHOD: This qualitative study used an inductive approach to analyze data from semistructured interviews with teaching faculty and education leaders at University of California, San Francisco, School of Medicine 6 months following the elimination of traditional tiered clerkship grades. Participants were recruited in 2019 using purposive sampling. Interview questions addressed participants' perceptions of the new approach to assessment and grading that emphasizes assessment for learning, including advantages and concerns. The authors analyzed data using thematic analysis informed by sensitizing concepts from CBAM. RESULTS: Nineteen faculty participated (11 medicine, 8 surgery). Faculty expressed optimism about the impact of the change on their clinical educator roles and sought faculty development to enhance feedback and assessment skills. Perceived benefits to students addressed learning and wellness, with concern for students' motivation and professional development. Faculty shared uncertainty about their roles and larger systemic consequences involving the residency match and institutional reputation. Participants acknowledged that traditional grading is imperfect, yet felt a departure from this system represented significant culture change. CONCLUSIONS: Faculty perceptions of the assessment and grade change in 2 large departments demonstrated tensions around grading. Their descriptions of change as an ongoing process aligned with CBAM and required them to consider new approaches and perspectives. While discourse about assessment and grading frequently focuses on learners, these findings support institutional consideration of the impact of changes in assessment on teaching faculty.

Near-Peer Learning During the Surgical Clerkship: A Way to Facilitate Learning After a 15-Month Preclinical Curriculum.

OBJECTIVES: To investigate the performance and perspectives of third-year medical students (MS3s) participating in near-peer learning (NPL) sessions during their core surgical clerkship following a 15-month preclerkship curriculum. DESIGN: An evaluation study of 7 NPL sessions developed and implemented by fourth-year medical students (MS4s) held from March 2019 to February 2020. MS4s taught 1-2 sessions per rotation that included test taking strategies, illness script development, radiology review, case-based multiple-choice questions, and rapid review. Participants completed a questionnaire with 11 seven-point Likert and open-ended questions after each session. Analyses included quantitative comparison of shelf score averages between NPL participants and nonparticipants and qualitative content analysis for open-ended questions. SETTING: Surgical clerkship at the University of California, San Francisco. PARTICIPANTS: Forty-eight (32%) MS3s participated, with an average attendance of 10 students per rotation. Thirty-three (69%) participants completed the questionnaire. RESULTS: MS3s enjoyed the session (6.9 ± 0.4), improved their knowledge (6.8 ± 0.5), and felt more prepared for the surgery shelf examination (6.5 ± 0.6). MS4 leaders found that MS3s always wanted radiology review, and their interest in test taking strategies and illness script development declined across the clerkship year. Participants had lower shelf exam scores compared to nonparticipants (68.1 vs 71.4, respectively; p = 0.04, ES = 0.03). Shelf exam scores increased over time in both cohorts. Each group had 2 shelf exam failures. Qualitative analysis suggests that MS3s appreciated the NPL's tailored approach and exam demystification, with a desire for increased NPL integration into the clerkship. CONCLUSION: Students participating in NPL were satisfied with the sessions. Participants may have been students who struggled as indicated by shelf exam scores and appreciated the support. The shift in preferred topics across the blocks reflects the students' development during clerkships. Near-peer teachers should adjust sessions over time to fit students' evolving needs.

Where Do We Go From Here? Assessing Medical Students' Surgery Clerkship Preparedness During COVID-19.

INTRODUCTION: The impact of COVID-19 on surgical education has been profound, and clinical learning experiences transitioned to virtual formats. This study investigated the impact of virtual experiences created to facilitate learning during the pandemic for medical students. METHODS: We performed a cohort study to determine the perceived clinical preparedness for medical students enrolled in the preclinical surgery pilot course, surgical Extended Mastery Learning Rotation (EMLR), and longitudinal surgical clerkship (LC). The preclinical surgery pilot course took place before COVID-19 disruptions, and the EMLR and LC experiences took place virtually. Specialty choice was examined in the EMLR and LC cohorts. Performance on the NBME surgical assessments was analyzed among students enrolled in the traditional clerkship and pandemic-disrupted courses and compared to national data using a two-sample t-test. RESULTS: Compared to preclinical students, EMLR and LC students demonstrated improvements in their perceived surgical clerkship readiness. After the 3-week EMLR course, in the setting of completing only one-third of the clerkship year, students had an average NBME Surgical Self-Assessment Exam score of 72 (SD 12), comparable to the national average of 71 (SD 9) p = 0.33. The average shelf exam score for students (N = 24) enrolled in the traditional clerkship (block 1), prior to COVID-19, disruptions was 66 (SD 9) compared to an average score of 69 (SD 9) for the longitudinal clerkship students (N = 20) that took the shelf exam later in the year (p = 0.36). COVID-19 disruptions did not affect specialty choice. All LC students have decided on a specialty; 50% nonsurgical and 50% surgical. From the EMLR cohort, 36% and 38% plan to pursue surgical and nonsurgical specialties, respectively, with 26% still undecided. CONCLUSIONS: Courses were well-liked and will be implemented in future clerkships. Surgical educators demonstrated flexibility and creativity in the development of the EMLR. Despite COVID-19 disruptions, medical students made progress in their clinical skills and foundational science knowledge. COVID-19 disruptions did not appear to impact specialty choice.

Solid pseudopapillary neoplasm of the pancreas: a rare and atypically aggressive disease among male patients.

Solid pseudopapillary neoplasm (SPN) of the pancreas is uncommon, has low metastatic potential, typically afflicts young females, and expresses progesterone receptors. In the rare male patient, its biologic behavior may be more aggressive and lethal. A retrospective case series analysis and literature review of SPN was performed to compare its clinical behaviors in males and females. The case series identified 11 patients of which only two were males. Ten patients underwent tumor resection with curative intent. The one operated male developed liver metastases 15 months postoperatively and subsequently died. The other male presented with advanced liver metastases and died 2 months later without operation. One female had regional lymph node metastases resected en bloc and all nine females are disease-free after a mean follow-up of 63.4 months. Analysis of 1014 patients reported in the literature revealed only 137 (13.5%) males. Males had a twofold higher incidence of metastases and a threefold higher death rate. In males, SPN has an atypically aggressive biology suggesting that progesterone and/or other sex hormones may have a role in oncoregulation.

Successful enhanced recovery program after colorectal surgery in a county institution.

Enhanced recovery programs after colorectal surgery have gained acceptance recently as they have shown a decrease length of hospital stay. However, these pathways require strict adherence to standardized programs with patient education and high compliance. This study was designed to assess the feasibility of such a program in a large county hospital. A retrospective review was performed of 54 consecutive patients who underwent laparoscopic or open segmental colorectal resection without an ostomy. The first 27 patients were treated in a conventional manner, whereas the latter 27 were treated using a protocol promoting early feeding and ambulation with decreased intravenous fluids and narcotic use. There were no baseline differences between the groups, however, there was a significant difference in the patients treated with the enhanced recovery program in terms of less intravenous fluids administered in surgery (P = 0.001), and over the subsequent 3 days (P = 0.0017), with a decrease in length of hospital stay of 4 compared with 6 days (P = 0.003). There were no differences in terms of complication and readmission rates. Based on this study, we conclude that strict adherence to a standard enhanced recovery program was effective in reducing hospital stay in patients undergoing colorectal resection without any increase in complications.

Characteristics of colorectal cancer among Asian Americans.

Colorectal cancer (CRC) is third in mortality rate amongst Asian Americans. However, CRC characteristics in this patient population have been poorly defined. A retrospective review at an urban tertiary hospital located in an underserved region was performed to determine CRC characteristics for Asian Americans in comparison to other races. Four hundred fourteen patients were represented by Hispanics (n=161), African Americans (n=101), Asians (n=83), and Whites (n=69). The majority of Asian American patients (n=70, 84%) presented with a left-sided lesion. This proportion was higher than that seen in African Americans (59%, P < 0.0003), Hispanics (66%, P < 0.0033), and Whites (63%, P < 0.0036). Thirty-six Asian American patients presented with Stage III disease which was the most frequent presenting stage for this patient population and also statistically higher than all the other races. Furthermore, Asian Americans in this study still presented predominantly with left-sided lesions and in a more advanced stage. These findings suggest a potential benefit of initially offering flexible sigmoidoscopy given the decreased compliance among Asian Americans to obtain routine CRC screening. Ultimately, this modality may be more acceptable, leading to higher compliance for CRC screening in Asian Americans without likely degradation in cancer detection rates.

Primary Colonic Lymphoma.

Primary colonic lymphoma is a rare large bowel malignancy usually found in the cecum or rectosigmoid junction. Because of its non-specific symptoms, patients often present with advanced disease requiring surgical intervention. Nevertheless, resection followed by chemotherapy appears to offer the best prognosis.

Subcutaneous Fat Fibrosis Links Obesity to Insulin Resistance in Chinese Americans.

Objective: Type 2 diabetes presents at a lower body mass index (BMI) in Chinese individuals than in white individuals. We sought to determine the role of subcutaneous adipose tissue (SCAT)-intrinsic factors, vs BMI or adiposity per se, in the vulnerability of Chinese individuals to obesity-associated impairment of insulin sensitivity. Research Design and Methods: Thirty-two Chinese and 30 white men and women from a cohort in the San Francisco Bay Area underwent anthropometric measurements, body composition (dual-energy X-ray absorptiometry) analyses, and measurement of fasting plasma glucose and insulin. Forty-eight also provided abdominal SCAT samples for transcriptional and biochemical analyses of tissue fibrosis. Results: BMI correlated with total body fat in white (r = 0.74, P < 0.001) but not Chinese individuals, whereas BMI correlated with visceral adipose tissue (VAT) accrual in both ethnicities (r = 0.88 and 0.81, respectively; P < 0.01). Insulin resistance (homeostatic model assessment of insulin resistance) worsened with VAT mass, but not total body fat, in Chinese subjects (r = 0.63, P < 0.01), whereas it worsened with both in white individuals. By contrast, SCAT mRNA levels of genes encoding profibrotic proteins rose remarkably along with both BMI and VAT mass in Chinese but not white subjects. Similarly, SCAT levels of hydroxyproline, an indicator of tissue collagen content that correlated with increasing VAT mass, were higher in Chinese vs white subjects, particularly in the setting of relative insulin resistance. Conclusions: Our findings dissociate BMI from adiposity in Chinese individuals and instead highlight SCAT fibrosis as a process linked to visceral adiposity and insulin resistance in this group.

Expanded indications for bariatric surgery: should patients on chronic steroids be offered bariatric procedures?

BACKGROUND: Patients who take chronic corticosteroids are increasingly referred for bariatric surgery. Little is known about their clinical outcomes. OBJECTIVE: Determine whether chronic steroid use is associated with increased morbidity and mortality after stapled bariatric procedures. SETTING: American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. METHODS: All patients who underwent laparoscopic sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass and were reported to the ACS-NSQIP from 2011 to 2013 were reviewed. Patients were grouped based on type of surgery and history of chronic steroid use. Primary outcome measures were mortality and serious morbidity in the first 30 days. Regression analyses were used to determine predictors of outcome. RESULTS: Of 23,798 patients who underwent laparoscopic sleeve gastrectomy and 38,184 who underwent Roux-en-Y gastric bypass, 385 (1.6%) and 430 (1.1%), respectively, were on chronic steroids. Patients on chronic steroids had a 3.4 times increased likelihood of dying within 30 days (95% confidence interval 1.4-8.1, P = .007), and 2-fold increased odds of serious complications (95% confidence interval 1.2-2.3, P = .008), regardless of surgery type. In multivariate regression, steroid usage remained an independent predictor of mortality and serious complications. CONCLUSION: In a large, nationally representative patient database, steroid use independently predicted mortality and serious postoperative complications after stapled bariatric procedures. Surgeons should be cautious about offering stapled bariatric procedures to patients on chronic steroids.

Peer video review and feedback improve performance in basic surgical skills.

BACKGROUND: Incorporation of home-video assessments allows flexibility in feedback but requires faculty time. Peer feedback (PF) may provide additional benefits while avoiding these constraints. METHODS: Twenty-four surgical interns completed a 12-week skills curriculum with home-video assignments focused on knot tying and suturing. Interns were randomized into 2 groups: PF or faculty feedback (FF). Peers and faculty provided feedback on home videos with checklists, global rating, and comments. Learners' skills were assessed at baseline, during, and at the conclusion of the curriculum. Performance of the 2 groups as rated by experts was compared. FF and PF were compared. RESULTS: Both groups improved from baseline, and the highest rated scores were seen on their home-video assessments. The PF group performed better at the final assessment than the FF group (effect size, .84). When using a checklist, there was no significant difference between scores given by peers and faculty. CONCLUSIONS: The PF group performed better at the final assessment, suggesting reviewing and analyzing another's performance may improve one's own performance. With checklists as guidance, peers can serve as raters comparable to faculty.
