RESUMO
BACKGROUND/PURPOSE: Documentation of resuscitation preferences is crucial for patients undergoing surgery. Unfortunately, this remains an area for improvement at many institutions. We conducted a quality improvement initiative to enhance documentation percentages by integrating perioperative resuscitation checks into the surgical workflow. Specifically, we aimed to increase the percentage of general surgery patients with documented resuscitation statuses from 82% to 90% within a 1-year period. METHODS: Three key change ideas were developed. First, surgical consent forms were modified to include the patient's resuscitation status. Second, the resuscitation status was added to the routinely used perioperative surgical checklist. Finally, patient resources on resuscitation processes and options were updated with support from patient partners. An audit survey was distributed mid-way through the interventions to evaluate process measures. RESULTS: The initiatives were successful in reaching our study aim of 90% documentation rate for all general surgery patients. The audit revealed a high uptake of the new consent forms, moderate use of the surgical checklist, and only a few patients for whom additional resuscitation details were added to their clinical note. CONCLUSIONS: We successfully increased the documentation percentage of resuscitation statuses within our large tertiary care center by incorporating checks into routine forms to prompt the conversation with patients early.

BACKGROUND: In Canada, residency programs do not have many objective measures for ranking candidates. Instead, ranking relies on subjective measures such as letters of reference, which can be affected by the genders of the writer and the applicant. Our study assesses letters of recommendation for a general surgery program in Canada to categorize differences in reference letters based on the genders of applicant and letter writer. METHODS: We assessed 215 reference letters from 51 general surgery candidates for systematic differences in the descriptors used for male and female applicants and differences based on male and female authorship. RESULTS: Female applicants were more often described as mature, pleasant and flexible. Male applicants were more often described as having initiative, completing research, earning awards and performing extracurricular activities. Female writers were more likely to highlight an applicant's interest, initiative, response to feedback, knowledge of their limits, flexibility, communication, achievement in research and awards, confidence and ability to be a good assistant. Significantly more female applicants had female letter writers, compared with male applicants. CONCLUSION: These differences may affect the acceptance of applicants based on their gender and the genders of people who recommend them. Future research is required to explore how these differences in how applicants are described may affect residency selection committees' perceptions and rankings of applicants.

Summary: Multiple studies confirm that point of care ultrasound (PoCUS) has a high sensitivity and specificity for cholelithiasis and cholecystitis. However, there is poor perceived reliability of biliary PoCUS by surgeons. This survey was performed to assess surgeons' opinions on using PoCUS in gallstone disease and barriers that exist for its institution. The majority (60.3%) of respondents reported a total lack of confidence in PoCUS for the diagnosis of biliary disease. Most felt the sensitivity of PoCUS was poor and had concerns about the user-dependent nature of the test and the lack of imaging details provided. If offered ideal clinical/laboratory findings with PoCUS results, only 4.7% of surgeons would definitely operate for unremitting biliary colic and 5.4% for cholecystitis. The ability to replicate findings independently increased confidence in clinical decision-making. Our findings suggest there is substantial distrust in biliary PoCUS but that specific ultrasound training for the surgical workforce may prove tremendously beneficial for its utilization.

INTRODUCTION: Duodenal necrosis is a rare complication of acute pancreatitis but can occur given the shared blood supply to the head of the pancreas and the duodenum. PRESENTATION OF CASE: A 55-year-old male presented with acute-on-chronic pancreatitis and a duodenal hematoma. The hematoma expanded to occlude the biliary tree and, shortly after, the duodenum necrosed and perforated. The patient required an emergent pancreaticoduodenectomy performed in two stages. DISCUSSION: Surgical management is complex and a difficult challenge for a general surgeon. Many advocate for wide drainage to create a controlled fistula using a malecot through the wall defect/separate duodenotomy/a retrograde jejunostomy tube. This case represents an extreme variation on this issue which was best managed by definitive resection given the extent of the necrosis. CONCLUSION: This case report demonstrates that duodenal hematoma and necrosis should be recognized as part of the spectrum of consequences of acute pancreatitis. General surgeons should have a surgical approach to this complication whether that be diversion or definitive resection.
RESUMO
BACKGROUND: Both laparoscopy and endoscopy are image-based procedures, which are less intuitive than traditional open surgery and require extensive training to reach adequate proficiency. Currently, there is lack of understanding as to how the skills in one image-based procedure translate to another, such as endoscopy to laparoscopy and vice versa. The aim of our study was to explore the relationship between endoscopic and laparoscopic skills using a Fundamentals of Laparoscopic Surgery (FLS) trainer, a traditional virtual reality endoscopic trainer and a "desk-top" endoscopic physical simulator. METHODS: Senior surgical residents from across Canada participating in an advanced laparoscopic foregut training course were enrolled in the study. Participants were assessed performing the FLS laparoscopic suturing task, the Endobubble 2 task (Simbionix, GI Mentor), and a forward viewing peg transfer on the novel Basics in Endoscopic Skills Training Box (BEST Box). RESULTS: There was significant correlation between the participant's skill in simulated laparoscopic suturing and simulated endoscopic skill using the BEST box (Pearson coefficient (r) was 0.551 (p = 0.033) and the coefficient of determination (r2) was 0.304). There was a trend towards correlation between laparoscopic suturing time and Endobubble 2 score, but this did not reach statistical significance (r = 0.458, p = 0.086; r2 = 0.210). CONCLUSIONS: Performance in the two physical simulators, laparoscopic suturing and simulated flexible endoscopy using the BEST box, showed a correlation. This study adds to the growing body of evidence that laparoscopic and endoscopic skills are complementary and has the potential to impact simulation training involving both skill sets.

BACKGROUND: Patients with uncomplicated biliary disease frequently present to the emergency department for assessment. To improve bedside clinical decision making, biliary point-of-care ultrasound (POCUS) in the emergency department has emerged as a diagnostic tool. The purpose of this study is to analyze the usefulness of POCUS in predicting the need for surgical intervention in biliary disease. METHODS: A retrospective study of patients visiting the emergency department who received a biliary POCUS from December 1, 2016 to July 15, 2017 was performed. The physician interpretations of the biliary POCUS scans were collected, as well as data from the electronic health records including lab values, the subsequent use of diagnostic imaging, surgical consultation or intervention, and 28 days follow-up for representation or complication. RESULTS: Two hundred and eighty-three patients were identified as having received biliary POCUS. Of the patients referred to general surgery who received biliary POCUS 43% received a cholecystectomy. For the outcome of cholecystectomy, the finding of gallstones on POCUS was 55% sensitive (95% CI 40% to 70%) and 92% specific (95% CI 87% to 95%). A sonographic Murphy's sign was 16% sensitive (95% CI 7% to 30%) but 95% specific (95% CI 92% to 97%) and, gallbladder wall thickness was 18% sensitive (95% CI 9% to 33%) and 98% specific (95% CI 95% to 99%). Patients who received POCUS but did not proceed to confirmatory radiology department imaging had a shorter length of stay (433 min ± 50 min vs. 309 min ± 30 min, P<0.001). DISCUSSION: Point-of-care biliary ultrasound performed by emergency physicians provides timely access to diagnostic information. Positive findings of gallstones and increased gallbladder wall thickness are highly predictive of the need for surgical intervention, and use of POCUS is associated with shorter ER visits. LEVEL OF EVIDENCE: Retrospective cohort study, level III.
RESUMO
INTRODUCTION: Spilled gallstones from a laparoscopic cholecystectomy can be a source of significant morbidity, most commonly causing abscesses and fistulae. Preventative measures for loss, careful removal during the initial surgery, and good documentation of any concern for remaining intraperitoneal stones needs to be performed with the initial surgery. CASE REPORT: An 80-year-old male with a history of complicated biliary disease resulting in a cholecystectomy presented to general surgery clinic with increasing symptoms of gastric outlet obstruction. CT imaging was concerning for a malignant process despite negative biopsies. A distal gastrectomy and Billroth II reconstruction was performed and final pathology showed dense inflammation with a single calcified stone incarcerated within the gastric wall of the inflamed pylorus and no malignancy. DISCUSSION: Stones lost during laparoscopic cholecystectomy are not innocuous and preventative measures for loss, careful removal during the initial surgery, and good documentation of any concern for remaining intraperitoneal stones. CONCLUSION: This is the first case of gastric outlet obstruction caused by an intramural obstruction of the pylorus from a spilled gallstone during a laparoscopic cholecystectomy and subsequent inflammation. This is an etiology that must be considered in new cases of gastric outlet obstruction and can mimic malignancy.
RESUMO
BACKGROUND: Modern practice guidelines recommend index cholecystectomy (IC) for patients admitted with gallstone pancreatitis (GSP). However, this benchmark has been difficult to widely achieve. Previous work has demonstrated that dedicated acute care surgery (ACS) services can facilitate IC. However, the associated financial costs and economic effectiveness of this intervention are unknown and represent potential barriers to ACS adoption. We investigated the impact of an ACS service at two hospitals before and after implementation on cost effectiveness, patient quality-adjusted life years (QALY) and impact on rates of IC. METHODS: All patients admitted with non-severe GSP to two tertiary care teaching hospitals from January 2008-May 2015 were reviewed. The diagnosis of GSP was confirmed upon review of clinical, biochemical and radiographic criteria. Patients were divided into three time periods based on the presence of ACS (none, at one hospital, at both hospitals). Data were collected regarding demographics, cholecystectomy timing, resource utilization, and associated costs. QALY analyses were performed and incremental cost effectiveness ratios were calculated comparing pre-ACS to post-ACS periods. RESULTS: In 435 patients admitted for GSP, IC increased from 16 to 76% after implementing an ACS service at both hospitals. There was a significant reduction in admissions and emergency room visits for GSP after introduction of ACS services (p < 0.001). There was no difference in length of stay or conversion to an open operation. The implementation of the ACS service was associated with a decrease in cost of $1162 per patient undergoing cholecystectomy, representing a 12.6% savings. The time period with both hospitals having established ACS services resulted in a highly favorable cost to quality-adjusted life year ratio (QALY gained and financial costs decreased). CONCLUSIONS: ACS services facilitate cost-effective management of GSP. The result is improved and timelier patient care with decreased healthcare costs. Hospitals without a dedicated ACS service should strongly consider adopting this model of care.

BACKGROUND: Dysfunction of the rapidly activating delayed rectifier K(+) channel (IKr) encoded by the human ether-à-go-go-related gene (hERG) is the primary cause of acquired long QT syndrome (LQTS). Fever has been reported to trigger LQTS in various conditions. OBJECTIVE: We aim to clarify the effect and underlying mechanisms of febrile temperature on hERG expressed in HEK cells, IKr in neonatal rat ventricular myocytes, and the QT interval in rabbits. METHODS: Western blot analysis was used to determine the expression of hERG channel protein in stably transfected HEK 293 cells. Immunocytochemistry was used to visualize the localization of hERG channels. The whole-cell patch clamp technique was used to record hERG K(+) current (IhERG) in hERG expressing HEK 293 cells, as well as IKr, transient outward K(+) current (Ito), and L-type Ca(2+) current (ICa) in neonatal rat ventricular myocytes. Electrocardiographic recordings were performed in an in vivo rabbit model. RESULTS: Compared with culture at 37°C, culture at 40°C reduced the mature hERG expression and IhERG in an extracellular K(+) concentration-dependent manner. Point mutations that remove the K(+) dependence of hERG-S624T and F627Y-also abolished the febrile temperature-induced hERG reduction. In neonatal rat ventricular myocytes, febrile temperature prolonged the action potential duration and selectively reduced IKr in a manner similar to low K(+) culture. In an in vivo rabbit model, fever and hypokalemia synergistically prolonged the QT interval. CONCLUSION: Febrile temperature facilitates the development of LQTS by expediting hERG degradation through altered K(+) dependence.
