Problem: Accommodations for injured and disabled surgical providers have to balance an individual's needs with measures that ensure sterility requirements, patient and provider safety. The highly specialized nature of the surgical environment poses challenges when implementing changes in the operating room and literature is limited on adaptive surgical hand preparation techniques necessary to maximize a disabled medical student's active participation in their surgical clerkship.
Intervention: This paper presents a detailed account of the development and implementation of an adaptive surgical hand preparation designed to address mobility needs, enabling a student's active participation and education in the surgical curriculum.
Introduction: Subjective surgeon interpretation of near-infrared perfusion video is limited by low inter-observer agreement and poor correlation to clinical outcomes. In contrast, quantification of indocyanine green fluorescence video (Q-ICG) correlates with histologic level of perfusion as well as clinical outcomes. Measuring dye volume over time, however, has limitations, such as it is not on-demand, has poor spatial resolution, and is not easily repeatable.

This study sought to quantify the effect of 1 year of clinical experience on performance obtaining SIC in the absence of formal informed consent education.
Design: In this case-control cohort study, PGY1 and PGY2 surgical residents in an academic program were surveyed regarding their experiences and confidence in obtaining SIC; then assessed obtaining informed consent for a right hemicolectomy from a standardized patient.
Introduction: Survival following emergency department thoracotomy (EDT) for patients in extremis is poor. Whether intervention in the operating room instead of EDT in select patients could lead to improved outcomes is unknown. We hypothesized that patients who underwent intervention in the operating room would have improved outcomes compared to those who underwent EDT.

However, optimizing its efficacy requires the selection of appropriate brain targets informed by neuroimaging and mechanistic understanding. Previous studies have established the feasibility of using portable brain imaging, combining functional near-infrared spectroscopy (fNIRS) with tDCS during Fundamentals of Laparoscopic Surgery (FLS) tasks.

A microstate-based common spatial pattern (CSP) analysis with linear discriminant analysis (LDA) was compared to a topography-preserving convolutional neural network (CNN) approach. Expert surgeons (N = 10) and novice medical residents (N = 13) performed laparoscopic suturing tasks, and EEG data from 8 experts and 13 novices were analysed.

However, throughout that conflict, enemy forces did not have parity with the weaponry, capability, or personnel of the US and allied forces. War against countries like China and Russia, who are considered near-peer adversaries in terms of capabilities, will challenge battlefield medical care in many different ways.

Aim: The goal of our study was to evaluate the use of portable neuroimaging measures to map the neural processes associated with learning basic surgical skills.
Approach: Twenty-one subjects completed 15 sessions of training on the fundamentals of laparoscopic surgery (FLS) suture with intracorporeal knot-tying task in a box trainer.
Error-based learning is one of the basic skill acquisition mechanisms that can be modeled as a perception-action system and investigated based on brain-behavior analysis during skill training. Here, the error-related chain of mental processes is postulated to depend on the skill level leading to a difference in the contextual switching of the brain states on error commission. Therefore, the objective of this paper was to compare error-related brain states, measured with multi-modal portable brain imaging, between experts and novices during the Fundamentals of Laparoscopic Surgery (FLS) "suturing and intracorporeal knot-tying" task (FLS complex task)-the most difficult among the five psychomotor FLS tasks.

Methods: Twelve experienced and fourteen novice participants completed this cross-sectional observational study. Participants performed three repetitions of the FLS suture with intracorporeal knot tying task in a standard box trainer.
Objective: To determine if laser speckle contrast imaging (LSCI) mitigates variations and subjectivity in the use and interpretation of indocyanine green (ICG) fluorescence in the current visualization paradigm of real-time intraoperative tissue blood flow/perfusion in clinically relevant scenarios.
Methods: De novo laparoscopic imaging form-factor detecting real-time blood flow using LSCI and blood volume by near-infrared fluorescence (NIRF) of ICG was compared to ICG NIRF alone, for dye-less real-time visualization of tissue blood flow/perfusion. Experienced surgeons examined LSCI and ICG in segmentally devascularized intestine, partial gastrectomy, and the renal hilum across six porcine models.

Fundamentals of Laparoscopic Surgery (FLS) is a standard education and training module with a set of basic surgical skills. During surgical skill acquisition, novices need to learn from errors due to perturbations in their performance which is one of the basic principles of motor skill acquisition. This study on thirteen healthy novice medical students and nine expert surgeons aimed to capture the brain state during error epochs using multimodal brain imaging by combining functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG).

Therefore, brain network and skilled behavior relationship were evaluated using functional near-infrared spectroscopy (fNIRS) from seven experienced right-handed surgeons and six right-handed medical students during the performance of Fundamentals of Laparoscopic Surgery (FLS) pattern of cutting tasks in a physical and a VR simulator. Multiple regression and path analysis (MRPA) found that the FLS performance score was statistically significantly related to the interregional directed functional connectivity from the right prefrontal cortex to the supplementary motor area with F (2, 114) = 9, p < 0.

We reviewed published manuscripts comparing robot-assisted cholecystectomy (RAC) and laparoscopic cholecystectomy (LC) to evaluate the relationship between COI disclosures and conclusions drawn on the procedure benefits and safety profile.
Methods: Searching Pubmed and Embase using key words "cholecystectomy", laparoscopic" and "robotic"/"robot-assisted" retrieved 345 publications.
Introduction: Laparoscopic sleeve gastrectomy (LSG) represents more than half of all bariatric procedures in the USA, and robot-assisted sleeve gastrectomy (RSG) is becoming increasingly common. There is a paucity of evidence regarding postoperative surgical outcomes (> 30 days) in RSG patients, especially as these patients move between multiple hospital systems.
Methods: Using 2012-2018 New York State's inpatient and ambulatory data from the Statewide Planning and Research Cooperative System, bivariate and multivariate analyses were employed to examine patient long-term outcomes, postoperative complications, and charges following RSG versus LSG in unmatched and propensity score-matched (PSM) samples.

Background: There are an estimated 100,000 cases of abdominal injury (ABI) in the USA, annually resulting in over $12 billion in direct medical cost and $18 billion in lost productivity. This study assesses the timeliness, safety, and efficacy of the surgical management of abdominal injuries (ABIs), hollow viscus injuries (HVIs), and colonic injuries (CIs) for patients residing in New York State (NYS).
Methods: Using data from NYS's Statewide Planning and Research Cooperative System (SPARCS), we identified all trauma patients with ABI admitted between 2006 and 2015.

Fundamentals of Laparoscopic Surgery (FLS) is a prerequisite for board certification in general surgery in the USA. In FLS, the suturing task with intracorporeal knot tying is considered the most complex task. Transcranial direct current stimulation (tDCS) of the dorsolateral prefrontal cortex (PFC) has been shown to facilitate FLS surgical skill acquisition where 2mA tDCS for 15min with the anode over F3 (10/10 EEG montage) and cathode over F4 has improved performance score in an open knot-tying task.
