Influence of Insurance Status on Subdural Hematoma Management: A National Trauma Data Bank Analysis.

BACKGROUND: Traumatic brain injury is a major public health concern with a rising incidence in the United States. Prior studies have looked at associations between insurance status and traumatic brain injury, but none have focused specifically on traumatic subdural hematomas (SDH). It is important to evaluate whether insurance and/or other social determinants of health play a role in treatment and outcomes of traumatic SDH. METHODS: A retrospective analysis of the National Trauma Data Bank was conducted from 2012 to 2016 to look at associations between insurance status and management of SDH with surgery versus intracranial pressure (ICP)/EVD monitoring. Secondary outcomes of interest were emergency department (ED) length of stay (LOS), hospital LOS, ICU admission, ICU LOS, and mortality. RESULTS: We identified 68,687 adult patients with a single diagnosis of subdural hematoma. Overall, self-pay patients with SDH were younger, predominately male, and more likely to be non-white compared to patients with public or private health insurance.  More specifically, Black/African American SDH patients made up a large percentage of the self-pay category (15.5%; P < 0.001) compared to publicly and privately insured (7.5% and 8.0%, respectively). After adjusting for age, sex, injury severity score (ISS), Glasgow Coma Scale, alcohol intoxication, and trauma center level, publicly insured patients were 1.86 (95% CI 1.36-2.55, P < 0.001) times more likely to undergo a craniotomy or craniectomy compared to self-pay patients. However, insurance status did not appear to impact whether a patient received ICP/EVD monitoring (OR 0.52; 95% CI 0.24-1.18, P = 0.118). There was no statistically significant difference in ED LOS, Hospital LOS, and ICU LOS between insurance categories. CONCLUSIONS: Publicly insured patients have higher odds of undergoing surgical management for traumatic SDH compared to self-pay patients. Further studies evaluating this association are warranted.

Hispanic Farmers Experience Shorter EMS Response Times but Longer Emergency Department Length of Stay Following Occupational Injuries.

BACKGROUND: Agriculture has the highest rate of fatal injuries by sector. Hispanic workers also experience more fatal work injuries than every other minority group combined. Pre-hospital and initial trauma evaluation represent an important marker to understand the impact of a trauma system. We sought to investigate whether Hispanic agricultural workers in the United States (US) experience disparities following traumatic occupational injuries in terms of pre-hospital and emergency department care. METHODS: We retrospectively analyzed the National Trauma Data Bank from 2012-2016 to understand differences between Hispanic and non-Hispanic farmers in Emergency Medical Services (EMS) response and transport times (minutes), transport mode, transfer rates, presentation to University or Level I trauma hospitals, Injury Severity Scores (ISS), length of stay (LOS) in the emergency department (ED, minutes) or hospital (days), need for the operating room (OR), admittance to the Intensive Care Unit (ICU), and mortality. RESULTS: A total of 6,161 farmers were included in our analyses (median age 47 years, females 7.0%). Multivariable analyses indicate differences regarding EMS response, EMS transport, and LOS in the ED. Rates of admission to the ICU, surgical operations, days on a ventilator, discharge from the hospital with supportive care, and mortality did not differ between groups. CONCLUSIONS: Non-Hispanic patients have longer median EMS response and total transport times. Hispanic patients have longer median LOS in the ED. However, the lack of significant differences in management variables other than EMS times and ED LOS indicate an equitable delivery of trauma care once patients were transferred from the ED.

A Fast-Track Pathway for Emergency General Surgery at an Academic Medical Center.

BACKGROUND: Fast Track Pathways (FTP) directed at reducing length of stay (LOS) and overall costs are being increasingly implemented for emergency surgeries. The purpose of this study is to evaluate implementation of a FTP for Emergency General Surgery (EGS) at an academic medical center (AMC). METHODS: The study included 165 patients at an AMC between 2016 and 2018 who underwent laparoscopic appendectomy (LA), laparoscopic cholecystectomy (LC), or laparoscopic inguinal hernia repair (LI). The FTP group enrolled 89 patients, and 76 controls prior to FTP implementation were evaluated. Time to surgery (TTS), LOS, and post-operative LOS between groups were compared. Direct costs, reimbursements, and patient reported satisfaction (satisfaction 1 = never, 4 = always) were also studied. RESULTS: The sample was 60.6% female, with a median age of 40 years. Case distribution differed slightly (56.2% versus 42.1% LA, 40.4% versus 57.9% LC, FTP versus control), but TTS was similar between groups (11h39min versus 10h02min, P = 0.633). LOS was significantly shorter in the FTP group (15h17min versus 29h09min, P < 0.001), reflected by shorter post-operative LOS (3h11min versus 20h10min, P< 0.001), fewer patients requiring a hospital bed and overnight stay (P < 0.001). Direct costs were significantly lower in the FTP group, reimbursements were similar (P < 0.001 and P = 0.999 respectively), and average patient reported satisfaction was good (3.3/4). CONCLUSION: In an era focused on decreasing cost, optimizing resources, and ensuring patient satisfaction, a FTP can play a significant role in EGS. At an AMC, an EGS FTP significantly decreased LOS, hospital bed utilization while not impacting reimbursement or patient satisfaction.

A Translational Model for Venous Thromboembolism: MicroRNA Expression in Hibernating Black Bears.

BACKGROUND: Hibernating American black bears have significantly different clotting parameters than their summer active counterparts, affording them protection against venous thromboembolism during prolonged periods of immobility. We sought to evaluate if significant differences exist between the expression of microRNAs in the plasma of hibernating black bears compared with their summer active counterparts, potentially contributing to differences in hemostasis during hibernation. MATERIALS AND METHODS: MicroRNA sequencing was assessed in plasma from 21 American black bears in summer active (n = 11) and hibernating states (n = 10), and microRNA signatures during hibernating and active state were established using both bear and human genome. MicroRNA targets were predicted using messenger RNA (mRNA) transcripts from black bear kidney cells. In vitro studies were performed to confirm the relationship between identified microRNAs and mRNA expression, using artificial microRNA and human liver cells. RESULTS: Using the bear genome, we identified 15 microRNAs differentially expressed in the plasma of hibernating black bears. Of these microRNAs, three were significantly downregulated (miR-141-3p, miR-200a-3p, and miR-200c-3p), were predicted to target SERPINC1, the gene for antithrombin, and demonstrated regulatory control of the gene mRNA expression in cell studies. CONCLUSIONS: Our findings suggest that the hibernating black bears' ability to maintain hemostasis and achieve protection from venous thromboembolism during prolonged periods of immobility may be due to changes in microRNA signatures and possible upregulation of antithrombin expression.

Treatment of Facial Fractures at a Level 1 Trauma Center: Do Medicaid and Non-Medicaid Enrollees Receive the Same Care?

BACKGROUND: Timing of surgical treatment of facial fractures may vary with the patient age, injury type, and presence of polytrauma. Previous studies using national data sets have suggested that trauma patients with government insurance experience fewer operations, longer length of hospital stay (LOS), and worse outcomes compared with privately insured patients. The objective of this study is to compare treatment of facial fractures in patients with and without Medicaid insurance (excluding Medicare). METHODS: All adults with mandibular, orbital, and midface fractures at a Level 1 Trauma Center between 2009 and 2018 were included. Statistical analyses were performed to assess the differences in the frequency of surgery, time to surgery (TTS), LOS, and mortality based on insurance type. RESULTS: The sample included 1541 patients with facial fractures (mandible, midface, orbital), of whom 78.8% were male, and 13.1% (208) were enrolled in Medicaid. Mechanism of injury was predominantly assault for Medicaid enrollees and falls or motor vehicle accidents for non-Medicaid enrollees (P < 0.001). Patients with mandible and midface fractures underwent similar rates of surgical repair. Medicaid enrollees with orbital fractures underwent less frequent surgery for facial fractures (24.8% versus 34.7%, P = 0.0443) and had higher rates of alcohol and drug intoxication compared with non-Medicaid enrollees (42.8% versus 31.6%, P = 0.008). TTS, LOS, and mortality were similar in both groups with facial fractures. CONCLUSIONS: Overall, the treatment of facial fractures was similar regardless of the insurance type, but Medicaid enrollees with orbital fractures experienced less frequent surgery for facial fractures. Further studies are needed to identify specific socioeconomic and geographic factors contributing to these disparities in care.

Intraabdominal infections in the intensive care unit.

Intraabdominal infections are frequent and dangerous entity in intensive care units. Mortality and morbidity are high, causes are numerous, and treatment options are variable. The intensivist is challenged to recognize and treat intraabdominal infections in a timely fashion to prevent complications and death. Diagnosis of intraabdominal infection is often complicated by confounding underlying disease or masked by overall comorbidity. Current research describes a wide heterogeneity of patient populations, making it difficult to suggest a general treatment regimen and stressing the need of an individualized approach to decision making. Early focus-oriented intervention and antibiotic coverage tailored to the individual patient and hospital is warranted.

Obesity increases the risk for upper extremity deep vein thrombosis and pulmonary embolism in patients with upper extremity central venous catheters.

The morbidity and mortality of deep vein thrombosis (DVT) remain a significant burden for the healthcare system. The aim of this analysis was to examine the association of upper extremity central venous catheter (UECVC) and venous thromboembolism (UEVTE) with increasing body mass index (BMI) in a large database study and to further examine disposition. Inpatient data from the National Inpatient Sample from 2017 to 2019 were used to investigate the effect of obesity on patients diagnosed with DVT of the upper extremity or pulmonary embolism (PE) who had upper extremity venous central line placement. There was a total of 1690 cases of UEVTE and 3202 cases of PE within the sample. There was an increasing odds of UEVTE in the patients with UECVCs with increasing BMI. Patients with a BMI of 30-39, 40-49 and > 50 kg/m2 were significantly different than those with BMI of <19 and 20-29 kg/m2 in the UECVC group for UEVTE. This study demonstrated increased odds of UEVTE for patients with increased BMI. Practitioners should assume a greater risk for UEVTE and PE in patients with increased BMI when considering CVCs.

Integration of basic clinical skills training in medical education: an interprofessional simulated teaching experience.

BACKGROUND: A 2004 survey reveals that the implementation of the 1998 AAMC report on medical student clinical skills training is slow. Given the importance of intravenous catheter placement, a creative approach evolved to educate medical students on this important skill. DESCRIPTION: As part of a community service learning initiative, six graduate nursing students developed, implemented, and evaluated a pilot IV Cannulation Education Module taught to medical students. EVALUATION: Data analysis of 63 participants reveals improved knowledge and confidence in medical students' ability to place an intravenous catheter. The objectives were met and the process enjoyed by students of both professions. CONCLUSION: Opportunities for interprofessional teaching and learning include clinical skills training. Medical students learned an important skill taught by graduate nursing students who developed and evaluated a curriculum that met their own graduate course objectives. Both professions appreciated the opportunity to work collaboratively to achieve their respective programmatic goals.

Treatment of Acute Cholecystitis: Do Medicaid and Non-Medicaid Enrolled Patients Receive the Same Care?

BACKGROUND: Nationally, Medicaid enrollees with emergency surgical conditions experience worse outcomes overall when compared with privately insured patients. The goal of this study is to investigate disparities in the treatment of cholecystitis based on insurance type and to identify contributing factors. METHODS: Adults with cholecystitis at a safety-net hospital in Central Massachusetts from 2017-2018 were included. Sociodemographic and clinical characteristics were compared based on Medicaid enrollment status (Medicare excluded). Univariate and multivariate analyses were used to compare the frequency of surgery, time to surgery (TTS), length of stay (LOS), and readmission rates between groups. RESULTS: The sample (n = 203) included 69 Medicaid enrollees (34%), with a mean age of 44.4 years. Medicaid enrollees were younger (p = 0.0006), had lower levels of formal education (high school diploma attainment, p < 0.0001), were more likely to be unmarried (p < 0.0001), Non-White (p = 0.0012), and require an interpreter (p < 0.0001). Patients in both groups experienced similar rates of laparoscopic cholecystectomy, TTS, and LOS; however, Medicaid enrollees experienced more readmissions within 30 days of discharge (30.4% vs 17.9%, p < 0.001). CONCLUSION: Despite anticipated population differences, the treatment of acute cholecystitis was similar between Medicaid and Non-Medicaid enrollees, with the exception of readmission. Further research is needed to identify patient, provider, and/or population factors driving this disparity.

Prevalence of thrombophilias in patients presenting for bariatric surgery.

BACKGROUND: The rise in bariatric surgery has driven an increased number of complications from venous thromboembolism (VTE). Evidence supports obesity as an independent risk factor for VTE, but the specific derangements underlying the hypercoagulability of obesity are not well defined. To better characterize VTE risk for the purpose of tailoring prophylactic strategies, we developed a protocol for thrombophilia screening in patients presenting for bariatric surgery at our institution. METHODS: Between April 2004 and April 2006, 180 bariatric surgery candidates underwent serologic screening for inherited thrombophilias (Factor V-Leiden mutation, low Protein C activity, low Protein S activity, Free Protein S deficiency) and acquired thrombophilias (D-Dimer elevation, Fibrinogen elevation, elevation of coagulation factors VIII, IX, and XI, elevation of Lupus anticoagulants and homocysteine level, and Antithrombin III deficiency). Prevalence rate of each thrombophilia in the subject group was compared to the actual prevalence rate of the general population. RESULTS: Most plasma markers of both inherited and acquired thrombophilias were identified in higher than expected proportions, including D-Dimer elevation in 31%, Fibrinogen elevation in 40%, Factor VIII elevation in 50%, Factor IX elevation in 64%, Factor XI elevation in 50%, and Lupus anticoagulant in 13%. CONCLUSIONS: Obesity is a well-described demographic risk factor for VTE. In bariatric surgery candidates routinely screened for serologic markers, both inherited and acquired thrombophilias occurred more frequently than in the general population, and may therefore prove to be useful for individualized VTE risk assessment and prophylaxis.

Risk-group targeted inferior vena cava filter placement in gastric bypass patients.

BACKGROUND: Despite a growing body of evidence guiding appropriate perioperative thromboprophylaxis in the general population, few data direct strategies to reduce deep venous thrombosis (DVT) and pulmonary embolism (PE) in the morbidly obese. We have implemented a novel protocol for venous thromboembolism (VTE) risk stratification in Roux-en-Y gastric bypass (RYGB) candidates at our institution, which augments clinical assessment with screening for thrombophilias, to guide retrievable inferior vena cava (IVC) filter utilization. METHODS: A retrospective review of prospectively collected data from patients who underwent primary RYGB between 2001 and 2008 at the University of North Carolina at Chapel Hill was completed. During that time, clinical assessment of VTE risk was amplified by focused plasma screening for common thrombophilias (factors VIII, IX, and XI, d-dimer, fibrinogen). Preoperative prophylactic IVC filters were offered to high-risk patients. The database was reviewed for perioperative DVTs, PEs, and filter-related complications. RESULTS: Of 330 patients, in 162 attempts, 160 had prophylactic IVC filters placed with four complications overall (2.47%). No patient had symptoms of PE during the planned 6-week filter period, though one had a PE occur immediately after filter removal (0.63%); in contrast, five of 170 patients (2.94%) without prophylactic IVC filters presented with symptomatic PE (p = 0.216). In total, 147 (91.88%) prophylactic filters were removed. CONCLUSIONS: Risk-group targeted prophylactic inferior vena cava filter placement prior to RYGB is safe with a trend towards reduced occurrence of PE.

Treatment of appendicitis: Do Medicaid and non-Medicaid-enrolled patients receive the same care?

BACKGROUND: Studies using national data sets have suggested that insurance type drives a disparity in the care of emergency surgery patients. Large databases lack the granularity that smaller, single-institution series may provide. The goal of this study is to identify factors that may account for differences in care between Medicaid and non-Medicaid enrollees with appendicitis in central Massachusetts. METHODS: All adult patients with acute appendicitis in an academic medical center between 2010 and 2018 were included. Sociodemographic and clinical characteristics were compared according to Medicaid enrollment status. Analyses were performed to assess differences in the frequency of operative treatment, time to surgery, length of stay, and rates of readmission. RESULTS: The sample included 1,257 patients, 10.7% of whom (n = 135) were enrolled in Medicaid. The proportions of patients presenting with perforated appendicitis (28.9% vs 31.2%, P = .857) and undergoing laparoscopic appendectomy (96.3% vs 90.7%, P = .081) were similar between the 2 groups, as were length of stay (20 hours 30 minutes versus 22 hours 38 minutes, P = .109) and readmission rates (17.8% vs 14.5%, P = .683). Medicaid enrollees did experience somewhat greater time to surgery (6 hours 47 minutes versus 4 hours 49 minutes, P < .001). CONCLUSION: Despite anticipated differences in population, the treatment of appendicitis was similar between Medicaid and non-Medicaid enrollees. Medicaid enrollees experienced greater time to surgery; however, further studies are needed to explain this disparity in care.

Role of Mucosal Protrusion Angle in Discriminating between True and False Masses of the Small Bowel on Video Capsule Endoscopy.

The diagnosis of small-bowel tumors is challenging due to their low incidence, nonspecific presentation, and limitations of traditional endoscopic techniques. In our study, we examined the utility of the mucosal protrusion angle in differentiating between true submucosal masses and bulges of the small bowel on video capsule endoscopy. We retrospectively reviewed video capsule endoscopies of 34 patients who had suspected small-bowel lesions between 2002 and 2017. Mucosal protrusion angles were defined as the angle between the small-bowel protruding lesion and surrounding mucosa and were measured using a protractor placed on a computer screen. We found that 25 patients were found to have true submucosal masses based on pathology and 9 patients had innocent bulges due to extrinsic compression. True submucosal masses had an average measured protrusion angle of 45.7 degrees ± 20.8 whereas innocent bulges had an average protrusion angle of 108.6 degrees ± 16.3 (p < 0.0001; unpaired t-test). Acute angle of protrusion accurately discriminated between true submucosal masses and extrinsic compression bulges on Fisher's exact test (p = 0.0001). Our findings suggest that mucosal protrusion angle is a simple and useful tool for differentiating between true masses and innocent bulges of the small bowel.

Laparoscopic cholecystectomy.

Laparoscopic cholecystectomy (LC) has supplanted open cholecystectomy for most gallbladder pathology. Experience has allowed the development of now well-established technical nuances, and training has raised the level of performance so that safe LC is possible. If safe cholecystectomy cannot be performed because of acute inflammation, LC tube placement should occur. A systematic approach in every case to open a window beyond the triangle of Calot, well up onto the liver bed, is essential for the safe completion of the operation.

The impact of deliberate reflection with WISE-MD™ modules on surgical clerkship students' critical thinking: a prospective, randomized controlled pilot study.

PURPOSE: Critical thinking underlies several Association of American Medical Colleges (AAMC)-defined core entrustable professional activities (EPAs). Critical-thinking ability affects health care quality and safety. Tested tools to teach, assess, improve, and nurture good critical-thinking skills are needed. This prospective randomized controlled pilot study evaluated the addition of deliberate reflection (DR), guidance with Web Initiative in Surgical Education (WISE-MD™) modules, to promote surgical clerks' critical-thinking ability. The goal was to promote the application of reflective awareness principles to enhance learning outcomes and critical thinking about the module content. PARTICIPANTS AND METHODS: Surgical clerkship (SC) students were recruited from two different blocks and randomly assigned to a control or intervention group. The intervention group was asked to record responses using a DR guide as they viewed two selected WISE-MD™ modules while the control group was asked to view two modules recording free thought. We hypothesized that the intervention group would show a significantly greater pre- to postintervention increase in critical-thinking ability than students in the control group. RESULTS: Neither group showed a difference in pre- and posttest free-thought critical-thinking outcomes; however, the intervention group verbalized more thoughtful clinical reasoning during the intervention. CONCLUSION: Despite an unsupported hypothesis, this study provides a forum for discussion in medical education. It took a sponsored tool in surgical education (WISE-MD™) and posed the toughest evaluation criteria of an educational intervention; does it affect the way we think? and not just what we learn, but how we learn it? The answer is significant and will require more resources before we arrive at a definitive answer.

Approach to the Diagnostic Workup and Management of Small Bowel Lesions at a Tertiary Care Center.

BACKGROUND: Small bowel lesions (SBL) are rare, representing diagnostic and management challenges. The purpose of this cross-sectional study was to evaluate diagnostic modalities used and management practices of patients with SBL at an advanced endoscopic referral center. METHODS: We analyzed patients undergoing surgical management for SBL from 2005 to 2015 at a single tertiary care center. Patients were stratified into gastrointestinal bleed/anemia (GIBA) or obstruction/pain (OP). RESULTS: One hundred and twelve patients underwent surgery after presenting with either GIBA (n = 67) or OP (n = 45). The mean age of our study population was 61.8 years and 45% were women. Patients with GIBA were more likely to have chronic or acute-on-chronic symptoms (100% vs 67%) and more often referred from outside hospitals (82 vs. 44%) (p < 0.01). The most common preoperative imaging modalities were video capsule endoscopy (VCE) (96%) for GIBA and computer tomography CT (78%) for OP. Findings on VCE and CT were most frequently concordant with operative findings in GIBA (67%) and OP (54%) patients, respectively. Intraoperatively, visual inspection or palpation of the bowel successfully identified lesions in 71% of patients. When performed in GIBA (n = 26), intraoperative enteroscopy (IE) confirmed or identified lesions in 69% of patients. Almost all (90%) GIBA patients underwent small bowel resections; most were laparoscopic-assisted (93%). Among patients with OP, 58% had a small bowel resection and the majority (81%) were laparoscopic-assisted. Surgical exploration failed to identify lesions in 10% of GIBA patients and 24% of OP patients. Among patients who underwent resections, 20% of GIBA patients had recurrent symptoms compared with 13% of OP patients. CONCLUSION: Management and identification of SBL is governed by presenting symptomatology. Optimal management includes VCE and IE for GIBA and CT scans for OP patients. Comprehensive evaluation may require referral to specialized centers.

Carcinoids and Capsules: A Case Series Highlighting the Utility of Capsule Endoscopy in Patients With Small Bowel Carcinoids.

BACKGROUND: Neuroendocine tumors (NETs) or carcinoids arise at many different sites of the gastrointestinal tract. The small intestine is the most common site for NETs. Diagnosing small bowel carcinoids remains challenging given their non-specific presentations and the overall low incidence of small bowel tumors. Video capsule endoscopy (VCE) has significanly improved our ability to detect small bowel malignancies. We explore the value of VCE in the initial workup and management of a series of small bowel carcinoid patients. METHODS: We retrospectively analyzed adult patients undergoing surgical management for small bowel lesions from July 2005 to September 2015 at a tertiary care center. Patient characteristics, presenting symptomatology, diagnostic workup and surgical management were analyzed among patients with histologically confirmed small bowel carcinoid tumors. RESULTS: Our study identified 16 patients treated surgically for small bowel carcinoids. The majority of patients (87.5%) presented with either occult gastrointestinal bleeding or anemia. Most patients (87.5%) were initially evaluated with various endoscopic and imaging modalities before all ultimately undergoing surgery. Seventy-five percent of patients had a VCE, with 83.3% (10/12) having positive findings that correlated with intraoperative findings compared to 62.5% (5/8) with computed tomography scan, 21.4% (3/14) with colonoscopy, 44% (4/9) with deep enteroscopy, and 0% (0/9) with esophagogastroduodenoscopy (EGD). CONCLUSIONS: In the absence of any contraindications, VCE is an effective endoscopic modality in the diagnostic workup of small bowel NETs. Furthermore, positive VCE findings appear to highly correlate with surgical findings, thus suggesting a valuable role for VCE in the initial surgical assessment of patients with small bowel NETs.

Cholecystostomy Treatment in an ICU Population: Complications and Risks.

BACKGROUND: Percutaneous cholecystostomy tube placement has widely been used as an alternative treatment to cholecystectomy, especially in advanced disease or critically ill patients. Reported postprocedural complication rates have varied significantly over the last decade. The goal of this study is to evaluate the safety of percutaneous cholecystostomy tube treatment in critically ill patients. STUDY DESIGN: We performed a retrospective chart analysis of 96 critically ill patients who underwent cholecystostomy tube placement during an intensive care unit (ICU) stay between 2005 and 2010 in a tertiary care center in central Massachusetts. Complications within 72 hours of cholecystostomy tube placement and any morbidity or mortality relating to presence of cholecystostomy tube were considered. RESULTS: A total of 65 male and 31 female patients with a mean age of 67.4 years underwent percutaneous cholecystostomy tube placement during an ICU stay. Sixty-six patients experienced a total of 121 complications, resulting in an overall complication rate of 69%. Fifty-four of these complications resulted from the actual procedure or the presence of the cholecystostomy tube; the other 67 complications occurred within 72 hours of the cholecystostomy procedure. Ten patients died. Tube dislodgment was the most common complication with a total of 34 episodes. CONCLUSIONS: Cholecystostomy tube placement is associated with frequent complications, the most common of which is tube dislodgment. Severe complications may contribute to serious morbidity and death in an ICU population. Complication rates may be underreported in the medical literature. The potential impact of cholecystostomy tube placement in critically ill patients should not be underestimated.

Timing and choice of intervention influences outcome in acute cholecystitis: a prospective study.

PURPOSE: Determine which management strategy is ideal for patients with acute cholecystitis. MATERIALS AND METHODS: Prospective enrollment between August 2009 and March 2011. Large academic center. Patients with acute cholecystitis. Laparoscopic cholecystectomy, intravenous antibiotics followed by laparoscopic cholecystectomy or percutaneous cholecystostomy. Primary endpoints were postoperative complications and 30-day mortality. RESULTS: A total of 162 patients were enrolled, 53 (33%) with simple acute cholecystitis and 109 (67%) with complex acute cholecystitis. Of the 109 patients with complex cholecystitis, 77 (70.6%) underwent successful laparoscopic cholecystectomy during the same hospital admission and 6 patients (5.5%) had an unsuccessful laparoscopic cholecystectomy requiring conversion to cholecystostomy. Radiology performed cholecystostomy in 19 (11.7%) patients with complex acute cholecystitis and 4 (2.5%) patients with simple acute cholecystitis for a total 23 patients of the 162 patients in the study. Nine of the 23 patients had dislodged tubes (39.1%). Two of the 23 patients (8.7%) had significant bile leaks resulting in either sepsis or emergency surgery. One patient (4.3%) had a wound infection. Overall, patients with complex acute cholecystitis had a higher morbidity rate (31.2%) compared with patients with simple acute cholecystitis (26.4%). CONCLUSIONS AND RELEVANCE: A high complication rate seen with radiology placed percutaneous cholecystostomy tubes prompted our center to reevaluate the treatment algorithm used to treat patients with complex acute cholecystitis. Although laparoscopic cholecystectomy is considered to be the gold standard in the treatment of acute cholecystitis, if laparoscopic cholecystectomy is not felt to be safe due to gallbladder wall thickening or symptoms of >72 hours' duration, we now encourage the use of intravenous antibiotics to "cool" patients down followed by interval laparoscopic cholecystectomy approximately 6 to 8 weeks later. Patients who do not respond to antibiotics should undergo attempted laparoscopic cholecystectomy and if unable to be performed safely, a laparoscopic cholecystostomy tube can be placed under direct visualization for decompression followed by interval laparoscopic cholecystectomy at a later date.
