Bridging the Gap: Comparison of Outpatient Clinic and Emergency Department Patients Undergoing Cholecystectomy.

INTRODUCTION: Literature shows failure of the outpatient clinic (OC) pathway after emergency department (ED) ultrasound diagnosis of symptomatic cholelithiasis (SC). We hypothesized SC to be more prevalent on final surgical pathology (FSP) in patients who successfully completed OC pathway. METHODS: This retrospective single-institution chart review compared OC and ED patients with right upper quadrant (RUQ) pain and cholelithiasis whom underwent cholecystectomy. Clinical evaluation was considered positive if RUQ pain >4 h, or + Murphy's sign. Ultrasound was positive if two of these three were present: sonographic Murphy's, wall thickness > 4 mm, or pericholecystic fluid. Results were compared with FSP. RESULTS: Six hundred-seven patients underwent cholecystectomy, 299 OC and 308 ED. OC was more likely to SC (23% versus 4.6%) (P < 0.0001) and ED acute cholecystitis (39.3% versus 4.7%). Chronic cholecystitis was the most common FSP in both OC (72%) and ED (56%) populations, of these, 73% of OC denied pain >4 h versus only 10% of ED (P < 0.001). Median time from evaluation to cholecystectomy was 14 d versus 14 h in the OC and ED respectively (P < 0.0001). CONCLUSIONS: While chronic cholecystitis was the most common FSP in both OC and ED, the majority of OC reported RUQ pain <4 h delineating these presentations. Duration of pain should be utilized as algorithm triage. We recommend patients with pain episode <4 h should complete OC algorithm with expedited cholecystectomy within 14 d.

Not all cholecystitis is created equal: Disparities contributing to ED presentation and failure of the outpatient algorithm.

BACKGROUND: The majority of final surgical pathology (FSP) from both emergency department (ED) and outpatient clinic (OC) patients is chronic cholecystitis. We aimed to differentiate these presentations and identify disparities associated with ED utilization and OC failure. METHODS: Retrospective chart review of single institution ED and OC cholecystectomies for cholelithiasis. Clinical presentation, FSP, demographics, and zip code poverty (ZCP) levels were evaluated. Data analysis by summary statistics, bivariate comparisons, and logistic regression. RESULTS: Of 299 OC and 308 ED patients, OC was more likely to be Caucasian (78% vs 46%, p < 0.0001) and insured (89% vs. 32%, p < 0.0001). 71.8% of OC with ZCP <10% had insurance versus only 32.5% in ZCP >20%. Uninsured ED OR was 13.1 (95% CI 8.7-22.9). CONCLUSION: Uninsured ED patients are vulnerable to fail the outpatient algorithm, especially when misdiagnosed by US. Clinical diagnosis of cholecystitis in this population should warrant offering of urgent cholecystectomy.

Survey shows all surgical residents have exposure to robotic surgery yet no formalized curricula exist amongst programs: A Southwest Surgical Congress Survey.

BACKGROUND: Increased robotic surgery exposure during general surgery training occurs at many institutions without a formal education curriculum. Our study evaluates the current state of general surgery robotic training within programs represented by the Southwestern Surgical Congress (SWSC). METHODS: A web-based survey regarding robot-assisted surgery (RAS) and general surgery training was developed and sent to member institutions of the SWSC. General surgery program directors were asked to voluntarily complete the survey. Results were evaluated in aggregate. Descriptive analysis was used. RESULTS: In total, 28 programs responded. All reported resident exposure to RAS during training. Case mix was diverse with exposure to multiple general surgical subspecialties. 89% of programs reported the presence of a formal RAS curriculum, however, only 53% reported recognition of training completion. Case volumes also varied amongst programs with 46% of programs reporting residents logging 21-40 cases and 35% logging more than 40 cases in total. CONCLUSION: Exposure to RAS among SWSC residency programs is ubiquitous, however, there is significant variation between programs in case volumes, case types, and elements of RAS curricula.

Patient characteristics and diagnostic tests associated with syncopal falls: A Southwestern surgical congress multicenter study.

BACKGROUND: Patients suspected of syncope frequently undergo laboratory and imaging studies to determine the etiology of the syncope. Variability exists in these workups across institutions. The purpose of this study was to evaluate the utilization and diagnostic yield of these workups and the patient characteristics associated with syncopal falls. METHODS: A multi-institutional retrospective review was performed on adult patients admitted after a fall between 1/2017-12/2018. Syncopal falls were compared to non-syncopal falls. RESULTS: 4478 patients were included. There were 795 (18%) patients with a syncopal fall. Electrocardiogram, troponin, echocardiogram, CT angiography (CTA), and carotid ultrasound were more frequently tested in syncope patients compared to non-syncope patients. Syncope patients had higher rates of positive telemetry/Holter monitoring, CTAs, and electroencephalograms. CONCLUSION: Patients who sustain syncopal falls frequently undergo diagnostic testing without a higher yield to determine the etiology of syncope.

Failure of nonoperative management of pediatric blunt liver and spleen injuries: A prospective Arizona-Texas-Oklahoma-Memphis-Arkansas Consortium study.

BACKGROUND: Nonoperative management (NOM) is standard of care for most pediatric blunt liver and spleen injuries (BLSI); only 5% of patients fail NOM in retrospective reports. No prospective studies examine failure of NOM of BLSI in children. The aim of this study was to determine the frequency and clinical characteristics of failure of NOM in pediatric BLSI patients. METHODS: A prospective observational study was conducted on patients 18 years or younger presenting to any of 10 Level I pediatric trauma centers April 2013 and January 2016 with BLSI on computed tomography. Management of BLSI was based on the Arizona-Texas-Oklahoma-Memphis-Arkansas Consortium pediatric guideline. Failure of NOM was defined as needing laparoscopy or laparotomy. RESULTS: A total of 1008 patients met inclusion; 499 (50%) had liver injury, 410 (41%) spleen injury, and 99 (10%) had both. Most patients were male (n = 624; 62%) with a median age of 10.3 years (interquartile range, 5.9, 14.2). A total of 69 (7%) underwent laparotomy or laparoscopy, but only 34 (3%) underwent surgery for spleen or liver bleeding. Other (nonexclusive) operations were for 21 intestinal injuries; 15 hematoma evacuations, washouts, or drain placements; 9 pancreatic injuries; 5 mesenteric injuries; 3 diaphragm injuries; and 2 bladder injuries. Patients who failed were more likely to receive blood (52 of 69 vs. 162 of 939; p < 0.001) and median time from injury to first blood transfusion was 2.3 hours for those who failed versus 5.9 hours for those who did not (p = 0.002). Overall mortality rate was 24% (8 of 34) in those who failed NOM due to bleeding. CONCLUSION: NOM fails in 7% of children with BLSI, but only 3% of patients failed for bleeding due to liver or spleen injury. For children failing NOM due to bleeding, the mortality was 24%. LEVEL OF EVIDENCE: Therapeutic study, level II.

Hypotension and the need for transfusion in pediatric blunt spleen and liver injury: An ATOMAC+ prospective study.

PURPOSE: Children with blunt liver or spleen injury (BLSI) requiring early transfusion may present without hypotension despite significant hypovolemia. This study sought to determine the relationship between early transfusion in pediatric BLSI and hypotension. METHODS: Secondary analysis of a 10-institution prospective observational study was performed of patients 18years and younger presenting with BLSI. Patients with central nervous system (CNS) injury were excluded. Children receiving blood transfusion within 4h of injury were evaluated. Time to first transfusion, vital signs, and physical exams were analyzed. Patients with hypotension were compared to those without hypotension. RESULTS: Of 1008 patients with BLSI, 47 patients met inclusion criteria. 22 (47%) had documented hypotension. There was no statistical difference in median time to first transfusion for those with or without hypotension (2h vs. 2.5h, p=0.107). The hypotensive group was older (median 15.0 versus 9.5years; p=0.007). Median transfusion volume in the first 24h was 18.2mL/kg (IQR: 9.6, 25.7) for those with hypotension and 13.9mL/kg (IQR: 8.3, 21.0) for those without (p=0.220). Mortality was 14% (3/22) in children with hypotension and 0% (0/25) in children without hypotension. CONCLUSION: Hypotension occurred in less than half of patients requiring early transfusion following pediatric BLSI suggesting that hypotension does not consistently predict the need for early transfusion. TYPE OF STUDY: Secondary analysis of a prospective observational study. LEVEL OF EVIDENCE: Level IV cohort study.

Does restraint status in motor vehicle crash with rollover predict the need for trauma team presence on arrival? An ATOMAC study.

PURPOSE: Restraint status has not been combined with mechanistic criteria for trauma team activation. This study aims to assess the relationship between motor vehicle crash rollover (MVC-R) mechanism with and without proper restraint and need for trauma team activation. METHODS: Patients <16years old involved in an MVC-R between November 2007 and November 2012 at 6 Level 1 pediatric trauma centers were included. Restraint status, the need for transfusion or intervention in the emergency department (ED), hospital and intensive care length of stay and mortality were assessed. RESULTS: Of 690 cases reviewed, 48% were improperly restrained. Improperly restrained children were more likely to require intubation (OR 10.24; 95% CI 2.42 to 91.69), receive blood in the ED (OR 4.06; 95% CI 1.43 to 14.17) and require intensive care (ICU) (OR; 3.11; 95% CI 1.96 to 4.93) than the properly restrained group. The improperly restrained group had a longer hospital length of stay (p<0.001), and a higher mortality (3.4% vs. 0.8%; OR 4.09; 95% CI 1.07 to 23.02) than the properly restrained group. CONCLUSION: Unrestrained children in MVC-R had higher injury severity and were significantly more likely to need urgent interventions compared to properly restrained children. This supports a modification to include restraint status with the rollover criterion for trauma team activation.

Informed consent training improves surgery resident performance in simulated encounters with standardized patients.

BACKGROUND: Although informed consent is vital to patient-physician communication, little training is provided to surgical trainees. We hypothesized that highlighting critical aspects of informed consent would improve resident performance. METHODS: Eighty (out of 88) surgical postgraduate year 1 surgical residents were randomly assigned to one of the 2 cases (laparoscopic cholecystectomy or ventral herniorrhaphy) and instructed to obtain and document informed consent with a standardized patient (SP) followed by a didactic training session. The residents then obtained and documented informed consent with the other case with the other SP. SPs graded encounters ("Checklist"); trained raters graded notes. Repeated measures multivariate analysis of variance (MANOVA) was used to determine differences between pre- and post-training and Checklist versus "Note" scores. RESULTS: Statistically significant pre- to post differences for Note (P < .01) and Checklist (P < .01) along with significant differences between Note and Checklist (P < .01) were noted. CONCLUSIONS: Training improved surgery residents' ability to discuss and document informed consent. Despite this improvement, significant differences between discussion and documentation persisted. Documentation training is a future area for improvement.

The use of laparoscopy in the diagnosis and treatment of blunt and penetrating abdominal injuries: 10-year experience at a level 1 trauma center.

BACKGROUND: Diagnostic laparoscopy (DL) has decreased the rate of nontherapeutic laparotomy for patients suffering from penetrating injuries. We evaluated whether DL similarly lowers the rate of nontherapeutic laparotomy for patients with blunt injuries. METHODS: All patients undergoing DL over a 10-year period (ie, 2001-2010) in a single level 1 trauma center were classified by the mechanism of injury. Demographic and perioperative data were compared using the Student t and Fisher exact tests. RESULTS: There were 131 patients included, 22 of whom sustained blunt injuries. Patients suffering from blunt injuries were more severely injured (Injury Severity Score 18.0 vs 7.3, P = .0001). The most common indication for DL after blunt injury was a computed tomographic scan concerning for bowel injury (59.1%). The rate of nontherapeutic laparotomy for patients sustaining penetrating vs blunt injury was 1.8% and nil, respectively. CONCLUSIONS: DL, when coupled with computed tomographic findings, is an effective tool for the initial management of patients with blunt injuries.
