Finding relief for the self-conscious esophagus: laparoscopic anti-reflux surgery and the esophageal hypersensitivity and anxiety scale.

INTRODUCTION: Measures of mood and effective coping strategies have notable correlations with quality of life and treatment responses. There is evidence that patients with previously diagnosed anxiety disorders have less improvement in patient-reported outcome measures (PROMs) after laparoscopic anti-reflux surgery (LARS) and that objective pathology does not correlate well with symptom severity. We were interested in investigating whether anxiety and hypervigilance, as measured preoperatively with the esophageal hypervigilance anxiety scale (EHAS), is associated with the improvement in GERD-specific PROMs and EHAS scores 6 months after LARS. METHODS: We performed a retrospective cohort study of 102 adult patients (31% men, average age 64) who underwent LARS. In the preoperative evaluation, baseline gastroesophageal reflux disease-health-related quality of life (GERD-HRQL), laryngopharyngeal reflux symptom index (LPR-RSI) and EHAS scores were collected in addition to the standard reflux workup, including endoscopy, manometry, barium swallow, and pH study. For all three surveys, a higher score represents worse symptom severity. At 6 months postoperatively, 70 patients completed repeat GERD-HRQL, LPR-RSI, and EHAS surveys. We then analyzed for surgical and patient-related factors associated with improvement in the 6-month postoperative GERD-HRQL and LPR-RSI scores. RESULTS: There was a statistically significant decrease in the GERD-HRQL (25 vs. 2, p < 0.001), LPR-RSI (17 vs. 3, p < 0.001) and EHAS (34 vs. 15, p < 0.001) 6 months after LARS. On multivariable linear regression, a higher baseline EHAS score was independently associated with a greater improvement in GERD-HRQL (ß 0.35, p < 0.001) and LPR-RSI (ß 0.19, p = 0.03) 6-months after LARS. Additionally, the degree of improvement in EHAS, GERD-HRQL, and LPR-RSI was not influenced by the type of LARS performed or by the severity of disease. CONCLUSION: These findings are consistent with literature suggesting that measures of psychoemotional health correlate better with symptom intensity than objective pathology. We found that patients with a higher EHAS score have greater symptom severity and lower quality of life at baseline. Novel findings to this study are that patients with a higher preoperative EHAS, a measure of psychoemotional health, actually benefitted more from surgery and not less, which has been the traditional view in the literature. Future studies are warranted to establish directionality and explore the role of preoperative cognitive behavioral therapy with LARS for patients with significant symptoms of hypervigilance and anxiety.

Psychoemotional factors and their influence on the quality of life in patients with GERD.

Patient-reported outcomes (PROs) are integral to determining the success of foregut surgical interventions and psychoemotional factors have been hypothesized to impact the quality of life of patients. This study evaluates the correlation between PROs-specifically the Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL) and the Laryngopharangeal Reflux Symptom Index (LPR-RSI)-and the recently validated Esophageal Hypervigilance Anxiety Scale (EHAS). We hypothesize that patients with higher EHAS scores have significantly elevated GERD-HRQL LPR-RSI compared to those with normal scores. EHAS has been developed and validated in chronic esophageal disorders, but clinical impact is unknown. In this retrospective study, 197 patients (38% men, average age 56 ± 16) completed the following surveys:(1) EHAS, (2) GERD-HRQL, and (3) LPR-RSI. All patients referred for surgical evaluation of GERD completed the surveys as part of their pre-operative workup and post-operative follow-up In bivariate analysis, EHAS correlated with both GERD-HRQL (r 0.53, P = <0.001) and LPR-RSI (r 0.36, P = 0.009). Accounting for potential confounding with sex and age in multivariable linear regression models, a higher GERD-HRQL score (ß 0.38; 95% CI 0.29 to 0.48; P = <0.001; Semipartial R2 0.20) and a higher LPR-RSI score (ß 0.21; 95% CI 0.13 to 0.29; P = <0.001; Semipartial R2 0.08) were independently associated with higher EHAS. The observed relationship between mental health and GERD symptom intensity is consistent with the biopsychosocial paradigm of illness. Future studies focused on post-surgical outcomes following the incorporation of EHAS into perioperative care is needed to evaluate its effectiveness as a clinical decision support tool in ARS.

Platelet Dysfunction after Traumatic Brain Injury: A Review.

Coagulopathy is a known sequela of traumatic brain injury (TBI) and can lead to increased morbidity and mortality. Platelet dysfunction has been identified as one of several etiologies of coagulopathy following TBI and has been associated with poor outcomes. Regardless of whether the platelet dysfunction occurs as a direct consequence of the injury or because of pre-existing medical comorbidities or medication use, accurate detection and monitoring of response to therapy is key to optimal patient care. Platelet transfusion has been proposed as a potential therapeutic intervention to treat platelet dysfunction, with several studies using platelet function assays to monitor response. The development of increasingly precise diagnostic testing is providing enhanced understanding of the specific derangement in the hemostatic process, allowing clinicians to provide patient-specific treatment plans. There is wide variability in the currently available literature on the incidence and clinical significance of platelet dysfunction following TBI, which creates challenges with developing evidence-based management guidelines. The relatively high prevalence of platelet inhibitor therapy serves as an additional confounding factor. In addition, the data are largely retrospective in nature. We performed a literature review to provide clarity on this clinical issue. We reviewed 348 abstracts, and included 97 manuscripts in our final literature review. Based on the currently available research, platelet dysfunction has been consistently demonstrated in patients with moderate-severe TBI. We recommend the use of platelet functional assays to evaluate patients with TBI. Platelet transfusion directed at platelet dysfunction may lead to improved clinical outcome. A randomized trial guided by implementation science could improve the applicability of these practices.

Desmopressin is a transfusion sparing option to reverse platelet dysfunction in patients with severe traumatic brain injury.

BACKGROUND: Platelet dysfunction (PD) is an independent predictor of mortality in patients with severe traumatic brain injury (sTBI). Platelet transfusions (PLTs) have been shown to be an effective treatment strategy to reverse platelet inhibition. Their use is contingent on availability and may be associated with increased cost and transfusion-related complications, making desmopressin (DDAVP) attractive. We hypothesized that DDAVP would correct PD similarly to PLTs in patients with sTBI. METHODS: This retrospective study evaluated all blunt trauma patients admitted to an urban, level 1 trauma center from July 2015 to October 2016 with sTBI (defined as head abbreviated injury scale [AIS] ≥3) and PD (defined as adenosine diphosphate [ADP] inhibition ≥60% on thromboelastography) and subsequently received treatment. Per our institutional practice, patients with sTBI and PD are transfused one unit of apheresis platelets to reverse inhibition. During a platelet shortage, we interchanged DDAVP for the initial treatment. Patients were classified as receiving DDAVP or PLT based on the initial treatment. RESULTS: A total of 57 patients were included (DDAVP, n = 23; PLT, n = 34). Patients who received DDAVP were more severely injured (injury severity score, 29 vs. 23; p = 0.045), but there was no difference in head AIS (4 vs. 4, p = 0.16). There was no difference between the two groups in admission platelet count (244 ± 68 × 10/µL vs. 265 ± 66 × 10/µL, p = 0.24) or other coagulation parameters such as prothrombin time, partial thromboplastin time, or international normalized ratio. Before treatment, both groups had similar ADP inhibition as measured by thromboelastography (ADP, 86% vs. 89%, p = 0.34). After treatment, both the DDAVP and PLT groups had similar correction of platelet ADP inhibition (p = 0.28). CONCLUSION: In patients with severe traumatic brain injury and PD, DDAVP may be an alternative to PLTs to correct PD. LEVEL OF EVIDENCE: Therapeutic, level IV.

Goal-directed platelet transfusions correct platelet dysfunction and may improve survival in patients with severe traumatic brain injury.

BACKGROUND: Platelet dysfunction, defined as adenosine diphosphate inhibition greater than 60% on thromboelastogram, is an independent predictor of increased mortality in patients with severe traumatic brain injury (TBI). We changed our practice to transfuse platelets for all patients with severe TBI and platelet dysfunction. We hypothesized that platelet transfusions would correct platelet dysfunction and improve mortality in patients with severe TBI. METHODS: This retrospective review included adult trauma patients admitted to our Level I trauma center from July 2015 to October 2016 with severe TBI (head Abbreviated Injury Scale score ≥ 3) who presented with platelet dysfunction and subsequently received a platelet transfusion. Serial thromboelastograms were obtained to characterize the impact of platelet transfusion on clot strength. Subsequently, the platelet transfusion group was compared to a group of historical controls with severe TBI patients and platelet dysfunction who did not receive platelet transfusion. RESULTS: A total of 35 patients with severe TBI presented with platelet dysfunction. Following platelet transfusion clot strength improved as represented by decreased K time, increased α angle, maximum amplitude, and G-value, as well as correction of adenosine diphosphate inhibition. When comparing to 51 historic controls with severe TBI and platelet dysfunction, the 35 study patients who received a platelet transfusion had a lower mortality (9% vs. 35%; p = 0.005). In stepwise logistic regression, platelet transfusion was independently associated with decreased mortality (odds ratio, 0.23; 95% confidence interval, 0.06-0.92; p = 0.038). CONCLUSION: In patients with severe TBI and platelet dysfunction, platelet transfusions correct platelet inhibition and may be associated with decreased mortality. LEVEL OF EVIDENCE: Therapeutic, level II.

Contemporary management of rectal injuries at Level I trauma centers: The results of an American Association for the Surgery of Trauma multi-institutional study.

INTRODUCTION: Rectal injuries have been historically treated with a combination of modalities including direct repair, resection, proximal diversion, presacral drainage, and distal rectal washout. We hypothesized that intraperitoneal rectal injuries may be selectively managed without diversion and the addition of distal rectal washout and presacral drainage in the management of extraperitoneal injuries are not beneficial. METHODS: This is an American Association for the Surgery of Trauma multi-institutional retrospective study from 2004 to 2015 of all patients who sustained a traumatic rectal injury and were admitted to one of the 22 participating centers. Demographics, mechanism, location and grade of injury, and management of rectal injury were collected. The primary outcome was abdominal complications (abdominal abscess, pelvic abscess, and fascial dehiscence). RESULTS: After exclusions, there were 785 patients in the cohort. Rectal injuries were intraperitoneal in 32%, extraperitoneal in 58%, both in 9%, and not documented in 1%. Rectal injury severity included the following grades I, 28%; II, 41%; III, 13%; IV, 12%; and V, 5%. Patients with intraperitoneal injury managed with a proximal diversion developed more abdominal complications (22% vs 10%, p = 0.003). Among patients with extraperitoneal injuries, there were more abdominal complications in patients who received proximal diversion (p = 0.0002), presacral drain (p = 0.004), or distal rectal washout (p = 0.002). After multivariate analysis, distal rectal washout [3.4 (1.4-8.5), p = 0.008] and presacral drain [2.6 (1.1-6.1), p = 0.02] were independent risk factors to develop abdominal complications. CONCLUSION: Most patients with intraperitoneal injuries undergo direct repair or resection as well as diversion, although diversion is not associated with improved outcomes. While 20% of patients with extraperitoneal injuries still receive a presacral drain and/or distal rectal washout, these additional maneuvers are independently associated with a three-fold increase in abdominal complications and should not be included in the treatment of extraperitoneal rectal injuries. LEVEL OF EVIDENCE: Therapeutic study, level III.
