Implementation of a Gastrografin Order Set for Small Bowel Obstruction Across a Health System: A Cohort Study.

BACKGROUND: The use of Gastrografin (GG) in the management of adhesive small bowel obstruction (SBO) has been shown to decrease the length of stay and operative intervention. METHODS: This retrospective cohort study examined patients with an SBO diagnosis prior to implementation (PRE, January 2017-January 2019) and following implementation (POST, January 2019-May 2021) of a GG challenge order set made available across 9 hospitals within a health care system. Primary outcomes were utilization of the order set across facilities and over time. Secondary outcomes included time to surgery for operative patients, rate of surgery, nonoperative length of stay, and 30-day readmission. Standard descriptive, univariate, and multivariable regression analyses were performed. RESULTS: PRE cohort had 1746 patients and POST had 1889. The utilization of GG increased from 14% to 49.5% following implementation. Significant variability existed within the hospital system with utilization at each individual hospital from 11.5% to 60%. There was an increase in surgical intervention (13.9% vs 16.4%, P = .04) and decrease in nonoperative LOS (65.6 vs 59.9 hours, P < .001) following implementation. For POST patients, multivariable linear regression showed significant reduction in nonoperative length of stay (-23.1 hours, P < .001) but no significant difference in time to surgery (-19.6 hours, P = .08). DISCUSSION: The availability of a standardized order set for SBO can result in increased Gastrografin administration across hospital settings. The implementation of a Gastrografin order set was associated with decreased length of stay in nonoperative patients.

Emergencies do not shut down during a pandemic: COVID pandemic impact on Acute Care Surgery volume and mortality at a level I trauma center.

BACKGROUND: The aim of this study was to evaluate the impact of the COVID-19 pandemic on volume and outcomes of Acute Care Surgery patients, and we hypothesized that inpatient mortality would increase due to COVID+ and resource constraints. METHODS: An American College of Surgeons verified Level I Trauma Center's trauma and operative emergency general surgery (EGS) registries were queried for all patients from Jan. 2019 to Dec. 2020. April 1st, 2020, was the demarcation date for pre- and during COVID pandemic. Primary outcome was inpatient mortality. RESULTS: There were 14,460 trauma and 3091 EGS patients, and month-over-month volumes of both remained similar (p > 0.05). Blunt trauma decreased by 7.4% and penetrating increased by 31%, with a concomitant 25% increase in initial operative management (p < 0.001). Despite this, trauma (3.7%) and EGS (2.9-3.0%) mortality rates remained stable which was confirmed on multivariate analysis; p > 0.05. COVID + mortality was 8.8% and 3.7% in trauma and EGS patients, respectively. CONCLUSION: Acute Care Surgeons provided high quality care to trauma and EGS patients during the pandemic without allowing excess mortality despite many hardships and resource constraints.

Improving enteral nutrition delivery in the critically ill trauma and surgical population.

BACKGROUND: Critically ill trauma and surgical patients often fail to achieve adequate enteral nutrition (EN) support. We hypothesize that implementation of an evidence-based, multidisciplinary nutrition enhancement protocol (EP) will improve delivery of EN in critically ill trauma and surgical patients and align our institution with nationally recommended guidelines. METHODS: The study compared patients prior to protocol (PP) with patients after implementation of the EP. The primary outcome was delivery of >80% of daily prescribed EN kilocalories in critically ill trauma and surgical patients during their intensive care unit stay. Data were prospectively captured from daily rounds and the electronic health record. Statistical analysis was conducted to compare data between groups using Student t test for continuous variables and chi-square test for categorical variables. RESULTS: In total, 256 patients in the PP group (2663 EN days) were compared with 232 patients in the EP group (2059 EN days). The primary outcome of average percentage of nutrition delivered (based on 24-h kilocalorie requirements) improved after the implementation of the EP (75.3% PP vs 85.5% EP; P < 0.01). This improvement was evident in surgical (69.9% PP vs 78.7% EP; P < 0.01) and trauma (78.2% PP vs 87.3% EP; P < 0.01) subpopulations. The secondary outcome of percentage of patients receiving >80% of nutrition goal also improved (52.7% PP vs 65.2% EP; P < 0.01). CONCLUSION: Implementation of an EP significantly increased delivery of EN by 10.2% and achieved compliance with American Society for Parenteral and Enteral Nutrition and Society of Critical Care Medicine recommended guidelines for critically ill trauma and surgical patients.

Perioperative hepatocyte growth factor (HGF) infusions improve hepatic regeneration following portal branch ligation (PBL) in rodents.

BACKGROUND: As hepatic surgery has become safer and more commonly performed, the extent of hepatic resections has increased. When there is not enough expected hepatic reserve to facilitate primary resection of hepatic tumors, a clinical adjunct to facilitating primary resection is portal vein embolization (PVE). PVE allows the hepatic remnant to increase to an appropriate size prior to resection via hepatocyte regeneration; however, PVE is not always successful in facilitating adequate regeneration. One of the strongest trophic factors for hepatocyte regeneration is hepatocyte growth factor (HGF). The purpose of this study was to improve hepatic regeneration with perioperative HGF infusions in an animal model that mimics PVE. METHODS: Portal branch ligation (PBL) in rodents is equivalent to PVE in humans. We performed left-sided PBL in Sprague-Dawley rodents with the experimental group receiving perioperative HGF infusions. Baseline and postoperative liver volumetrics were obtained with CT scanning methods as performed in clinical practice. Baseline and postoperative liver functions were assessed via indocyanine green (ICG) elimination testing. RESULTS: HGF infused rodents had statistically significant increase in all postoperative liver volumetrics. Most clinically relevant were increased right liver volumes (RLV), 14.10 versus 7.85 cm3 (p value 0.0001), and increased degree of hypertrophy (DH %), 159.23 versus 47.11 % (p value 0.0079). HGF infused rodents also had a quick return to baseline liver function, 2.38 days compared to 6.13 days (p value 0.0001). CONCLUSION: Perioperative HGF infusions significantly increase hepatic regeneration following PBL in rodents. Perioperative HGF infusions following PVE are a possible adjunct to increase the amount of patients able to successfully undergo primary resection for hepatic tumors. Further basic science is warranted in examining the use of HGF infusions to increase hepatic regeneration and translating that basic science work to clinical practice.

Stapled versus hand-sewn anastomoses in emergency general surgery: a retrospective review of outcomes in a unique patient population.

BACKGROUND: Recent studies have identified unique clinical and physiologic characteristics of emergency general surgery (EGS) patients and called for outcomes data in this population. There are no data in the US literature analyzing the impact of technique on anastomotic failure rates in EGS patients. The purpose of the current study was to compare outcomes of hand-sewn (HS) versus stapled (ST) bowel anastomoses in EGS patients. METHODS: A retrospective chart review of all patients admitted by our EGS service undergoing bowel resection for emergent indications from January 2007 to July 2011 was performed. Time from surgery to diagnosis of anastomotic failure was recorded as were the diagnostic modality and treatment of each anastomotic failure. Specific data on damage-control techniques, if used, were also collected. RESULTS: There were 100 HS (43%), and 133 ST (57%) anastomoses in 231 patients. Operative times were shorter in ST anastomosis technique (205 minutes for HS vs. 193 minutes for ST, p = 0.02). Anastomotic failures were identified in 26 patients (11%) and were significantly higher in the ST group than the HS group (15.0% vs. 6.1%, p = 0.003). A multivariate logistic regression analysis, controlling for age and preoperative nutritional status, revealed ST technique to be an independent risk factor for anastomotic failure (odds ratio, 2.65; 95% confidence interval, 1.08-6.50; p = 0.034). CONCLUSION: Anastomotic failures are more than twice as likely with ST than HS anastomoses in the EGS population. This is true even when controlling for markers of preoperative nutrition and demographics. These data suggest that the HS anastomosis should be the preferred method of reconstruction after bowel resection in EGS patients.
