RESUMEN
OBJECTIVE: Traditionally, expert surgeons have provided surgical trainees with feedback about their simulation performance, including for asynchronous practice. Unfortunately, innumerable time demands may limit experts' ability to provide feedback. It is unknown whether and how peer feedback is an effective mechanism to help residents acquire laparoscopic skill in an asynchronous setting. As such, we aimed to assess the effect of peer feedback on laparoscopic performance and determine how residents perceive giving and receiving peer feedback. DESIGN: We conducted a convergent mixed methods study. In the quantitative component, we randomized residents to receive feedback on home laparoscopic tasks from peers or faculty. We then held an end-of-curriculum, in-person laparoscopic assessment with members from both groups and compared performance on the in-person assessment between the groups. In the qualitative component, we conducted interviews with resident participants to explore experiences with feedback and performance. Three authors coded and rigorously reviewed interview data using a directed content analysis. SETTING: We performed this study at a single tertiary academic institution: the University of California, San Francisco. PARTICIPANTS: We invited 47 junior residents in general surgery, obstetrics-gynecology, and urology to participate, of whom 37 (79%) participated in the home curriculum and 25 (53%) participated in the end-of-curriculum assessment. RESULTS: Residents in the peer feedback group scored similarly on the final assessment (mean 70.7%; SD 16.1%) as residents in the faculty feedback group (mean 71.8%; SD 11.9%) (pâ¯=â¯0.86). Through qualitative analysis of interviews with 13 residents, we identified key reasons for peer feedback's efficacy: shared mental models, the ability to brainstorm and appreciate new approaches, and a low-stakes learning environment. CONCLUSIONS: We found that peer and faculty feedback led to similar performance in basic laparoscopy and that residents engaged positively with peer feedback, suggesting that peer feedback can be used when residents learn basic laparoscopy.

Objective: To determine whether socio-demographic and preoperative clinical factors contribute to the percent total body weight loss (%TBWL) after bariatric surgery (BS). Background: BS is the most effective long-term treatment for medically complicated obesity. More information is needed about the factors that contribute to postoperative %TBWL in large and ethnically diverse cohorts. Methods: This retrospective study conducted in the Kaiser Permanente Northern California region included 7698 patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between January 2009 and March 2015. Trajectory analyses were conducted from 5-year follow-up data to assign patients to "low," "average," or "high" postoperative %TBWL groups. We then evaluated whether age, sex, race/ethnicity, neighborhood deprivation index and preoperative body mass index (BMI)/weight loss, diabetes, hypertension, and sleep apnea contributed to postoperative %TBWL using logistic regression models. Results: Of 7698 patients (83.2% women), 48.6% underwent a RYGB and 51.4% underwent a SG. Postoperative %TBWL trajectories over 5 years were obtained in 6229 (81%) of 7698 eligible patients. About 27.8% and 29.3% of patients followed the "low" postoperative %TBWL trajectory, for RYGB and SG, respectively. Men, older patients, and Asian, Black, and Hispanic/Latino patients were more likely to be classified in the low postoperative %TBWL group. Patients showing lower postoperative %TBWL had a lower preoperative BMI (but lost less weight before surgery) and were more likely to have preoperative comorbidities. Conclusions: This study confirms and extends prior findings of the effects of several demographic and preoperative clinical factors on postoperative weight loss. Findings could improve the support of patients to achieve desired surgical outcomes.
RESUMEN
BACKGROUND: The field of robotic-assisted surgery is rapidly growing as many robotic surgical devices are in development and about to enter the market. Currently, there is no universally accepted language for labeling the different robotic systems. To facilitate this communication, we created what is, to our knowledge, the first classification of surgical robotic technologies that organizes and classifies surgical robots used for endoscopy, laparoscopy and thoracoscopy. METHODS: We compiled a list of surgical robots intended to be used for endoscopy, laparoscopy, and/or thoracoscopy by searching United States, European, Hong Kong, Japan, and Korean databases for approved devices. Devices showcased at the 2023 Annual Meeting for the Society of Robotic Surgery were added. We also systematically reviewed the literature for any existing surgical robotic classifications or categorizations. We then created a multidisciplinary committee of 8 surgeons and 2 engineers to construct a proposed classification of the devices included in our search. RESULTS: We identified 40 robotic surgery systems intended to be used for endoscopy, laparoscopy and/or thoracoscopy. The proposed classification organizes robotic devices with regard to architecture, port design, and configuration (modular carts, multi-arm integrated cart, table-attachable or arm-table integration). CONCLUSION: This 3-level classification of robotic surgical devices used for endoscopy, laparoscopy and/or thoracoscopy describes important characteristics of robotic devices systematically.

IMPORTANCE: American football is a popular high-impact sport, leading to 2.7 million injuries in the United States annually. Recent evidence in football-related neurological damage has spurred national interest in player-safety. Football players injure their head and neck in up to 26% of total injuries. Variation in injury patterns between age groups and correlated hospitalizations for football-related head and neck injury has yet to be characterized. OBJECTIVE: Our aim is to evaluate injury patterns among American-football related head and neck trauma. METHODS: A retrospective cohort study of patients with football-related head and neck injury in the National Electronic Injury Surveillance System (NEISS). RESULTS: Nearly 100 000 ED visits for football-related head and neck injuries occur annually. Males comprised 95% of patients, with a median age of 13. The head comprised 70% of injuries followed by the face (13%). The most common diagnoses were concussions (39%), internal organ injury (26%), and lacerations (11%). Pediatric patients were more likely to sustain concussions while adults experienced more lacerations (P < .05%). Fractures and nerve damage were rare injuries but caused a disproportionate share of hospitalizations. CONCLUSION: Pediatric males are most likely to present for emergency care from football-related injury to the head and neck. Evaluating physicians can anticipate concussions, internal organ injury, and lacerations among presenting patients. Concussions, facial fractures, and nerve damage are injuries most likely to lead to hospitalization.

INTRODUCTION: A new technology in medical education is ultrasound simulation, which has been shown to help students learn while reducing load on clinical instructors. The goal of this study is to compare the efficacy of teaching using ultrasound simulators versus more traditional instructor-led sessions with ultrasound machines. METHODS: Ultrasound was used to teach cardiac anatomy and physiology to medical students. Volunteers in one group were instructed using an ultrasound simulator (SonoSim) with built-in lessons; the other group received a traditional instructor-led session with an ultrasound machine. Efficacy of each type of teaching was assessed by measuring improvement from a pre-session test to a post-session test, using a one-sample paired t-test to compare averages between groups. Participants were given a survey to solicit opinions of the lessons. RESULTS: Twenty-one medical students participated, with 12 in the instructor-led group and 9 in the simulator group. Both groups increased their test scores from pre-session to post-session; the average increase was 5% in the instructor-led and 10% in the simulator group (p = 0.437). There was no statistically significant difference between groups in how effective or enjoyable the lesson felt. Participants from either group who tried both methods were likely to prefer the traditional ultrasound teaching. CONCLUSION: Self-guided learning with simulators and traditional instructor-led lectures are both effective for teaching basic cardiac anatomy and physiology via ultrasound. However, most students prefer learning with instructors if given the opportunity. Self-guided ultrasound simulators may serve as an effective standalone learning method or an adjunct to instructor-led sessions.
RESUMEN
INTRODUCTION: Opioids are administered during the intraoperative and postoperative periods in pediatric adenotonsillectomy and tonsillectomy. Non-opioid analgesics are often used as an analgesic during pediatric adenotonsillectomy and tonsillectomy. In this hypothesis generating study, we are evaluating safety and efficacy of stand-alone opioid analgesia for adenotonsillectomy and tonsillectomy. METHODS: This is a single-center retrospective chart review of patients ages 2 to 13 who underwent elective adenotonsillectomy and tonsillectomy. We used a convenience sampling method to select patients who received intraoperative intravenous fentanyl, acetaminophen, ibuprofen, or any combination thereof. The following outcomes were analyzed in this study: (i) the length of Post Anesthesia Care Unit stay, (ii) administration of postoperative opioids; (iii) postoperative opioid equivalents required; (iv) administration of postoperative non-opioid analgesics; and (v) inpatient admission from ED within 30 days. We used univariate analysis to compare the data points. RESULTS: We analyzed data from 323 patients who underwent adenotonsillectomy and tonsillectomy. The Post Anesthesia Care Unit length stay was similar for the intraoperative opioid-free and intraoperative opioid groups, 146.68 (±67.35) and 143.18 (±37.85) minutes, respectively (p = 0.586). Additionally, 102 patients (73.4%) in the intraoperative opioid-free group and 184 patients (83.2%) in the intraoperative opioid group did not receive any postoperative opioids (p = 0.033). The incidence of adverse events was similar between the intraoperative opioid-free and intraoperative opioid groups 3 (2.2%) and 5 (2.7%) respectively, p-value 0.749. A subgroup analysis comparing extracapsular 235 (72.8%) versus intracapsular 88 (27.2%) tonsillectomy yielded similar results. CONCLUSION: In this study, our data indicates that American Society of Anesthesiologists I- II pediatric patients undergoing adenotonsillectomy and tonsillectomy can be efficiently and safely managed with an opioid-free intraoperative and postoperative analgesic regimen. Due to the explained limitations, our study results should be interpreted cautiously.

OBJECTIVE: Head trauma can cause deafness in cases with and without a skull base fracture. Anatomic disruption can occur with skull base fractures, but inner ear structures can also be damaged by the concussive forces of the trauma even without fracture. It is thought that negative prognostic indicators for successful cochlear implantation (CI) for hearing rehabilitation include fractures involving the otic capsule or ossification of the cochlea. This review evaluates success of CI in posttrauma patients. DATA SOURCES: PubMed/MEDLINE, Cochrane, and Embase. STUDY SELECTION: Search terms used were "cochlear implant" AND ("trauma" OR "fracture"). Studies including preoperative computed tomography or magnetic resonance imaging and patient-level outcome data were included. DATA EXTRACTION: Study design, perioperative and postoperative outcomes, and complications were reported. Success rates of CI were compared using χ analysis. DATA SYNTHESIS: Twenty-three studies encompassing 88 patients who experienced posttraumatic deafness and received subsequent CI were included. CI was reported as successful for 28 of 34 patients (82%) with otic capsule-involving fracture, as compared with 17 of 22 (77%) in those who had an otic capsule-sparing temporal bone fracture, and 15 of 17 (88%) of patients without evidence of fracture (i.e., concussive inner ear injury). CONCLUSIONS: In patients with posttraumatic hearing loss, success rates do not significantly differ between cases that do or do not involve fractures of the otic capsule. CI for posttraumatic hearing loss is generally successful.

The objective of this article is to estimate the incidence, injury patterns, and demographics of patients presenting to emergency departments (EDs) for facial injury sustained from fireworks. This was an analysis of a nationwide database. The National Electronic Injury Surveillance System (NEISS) was evaluated for facial injuries from fireworks from 2013 to 2017. Relevant entries were examined for incidence, patient characteristics, location of injury, and type of injury. There were 509 NEISS entries, extrapolating to an estimated 19,816 ED visits for head and neck injuries due to fireworks from 2013 to 2017. The number of visits per year due to fireworks has been relatively stable over the past 5 years with an average of 3,963 cases per year. Greater than 90% of injuries occurred in July. Males comprised the majority of patients (67%), with the median age of 16 years. Most common sites of injury were the eyeballs (41%), followed by midface including eyelids, periorbita, and nose (31%), ears (12%), and only minor incidence of oral injuries (2%). After burns, contusions were the second most common injury from fireworks, followed by lacerations and foreign body injuries. The majority of firework injuries occurred in teenagers, reinforcing the importance of greater safety regulations and age limits for purchasing fireworks. Nearly half the incidents were eye injuries, necessitating greater public education in protective eyewear and mandating their use during festive holidays. Furthermore, injury patterns reported in this analysis may serve as a valuable adjunct for enhancing clinical history taking and physical examination to look for concurrent injuries.
