Addressing Adverse Childhood Experiences and Psychological Symptoms Among Bariatric Patients.

Adverse Childhood Experiences (ACEs) have been shown to be prevalent in bariatric surgery candidates with comorbid psychological symptoms. While bariatric patients who have mental illness or a history of ACEs are less likely to lose weight, presence of a support system has been reported to mitigate ACEs' effects and to maintain long-term weight loss. The current study aims to examine the association between ACEs and psychological symptoms and the effect of potential protective factors on the association among bariatric patients. The study included a total of 199 subjects seeking bariatric surgery who completed a psychological evaluation including ACEs, psychological symptoms, and presence of support system as part of the presurgical multidisciplinary weight management consultations at a large university hospital. Multivariate regression models were used to examine the association between ACEs and psychological symptoms and potential effect of support system on the association. The study found that there is a significant association between ACEs and psychological symptoms. The study also revealed that patients who reported having a childhood supportive person were significantly associated with a lower BMI, while those who reported having adulthood supportive person showed significantly less symptoms of depression, anxiety, and binge eating. The findings have significant implications that addressing ACEs in preoperative surgical process in relation to psychological conditions and therapeutic interventions within their close environmental system will be beneficial for patients to achieve optimal surgical outcomes.

Cardiovascular Outcomes and Mortality After Bariatric Surgery in Patients With Nonalcoholic Fatty Liver Disease and Obesity.

Importance: Bariatric surgery (BS) is associated with significantly reduced incidence of cardiovascular diseases and mortality in patients with obesity. However, whether BS can decrease major adverse cardiovascular events in patients with nonalcoholic fatty liver disease (NAFLD) remains poorly understood. Objective: To investigate the association of BS with the incidence of adverse cardiovascular events and all-cause mortality in patients with NAFLD and obesity. Design, Setting, and Participants: This was a large, population-based, retrospective cohort using data from the TriNetX platform. Adult patients with a body mass index (BMI, calculated as weight in kilograms divided by height in meters squared) of 35 or greater and NAFLD (without cirrhosis) who underwent BS between January 1, 2005, and December 31, 2021, were included. Patients in the BS group were matched with patients who did not undergo surgery (non-BS group) according to age, demographics, comorbidities, and medication by using 1:1 propensity matching. Patient follow-up ended on August 31, 2022, and data were analyzed in September 2022. Exposures: Bariatric surgery vs nonsurgical care. Main Outcomes and Measures: The primary outcomes were defined as the first incidence of new-onset heart failure (HF), composite cardiovascular events (unstable angina, myocardial infarction, or revascularization, including percutaneous coronary intervention or coronary artery bypass graft), composite cerebrovascular disease (ischemic or hemorrhagic stroke, cerebral infarction, transient ischemic attack, carotid intervention, or surgery), and a composite of coronary artery procedures or surgeries (coronary stenting, percutaneous coronary intervention, or coronary artery bypass). Cox proportional hazards models were used to estimate hazard ratios (HRs). Results: Of 152 394 eligible adults, 4693 individuals underwent BS; 4687 patients who underwent BS (mean [SD] age, 44.8 [11.6] years; 3822 [81.5%] female) were matched with 4687 individuals (mean [SD] age, 44.7 [13.2] years; 3883 [82.8%] years) who did not undergo BS. The BS group had significantly lower risk of new-onset of HF (HR, 0.60; 95% CI, 0.51-0.70), cardiovascular events (HR, 0.53; 95% CI, 0.44-0.65), cerebrovascular events (HR, 0.59; 95% CI, 0.51-0.69), and coronary artery interventions (HR, 0.47; 95% CI, 0.35-0.63) compared with the non-BS group. Similarly, all-cause mortality was substantially lower in the BS group (HR, 0.56; 95% CI, 0.42-0.74). These outcomes were consistent at follow-up duration of 1, 3, 5, and 7 years. Conclusions and Relevance: These findings suggest that BS was significantly associated with lower risk of major adverse cardiovascular events and all-cause mortality in patients with NAFLD and obesity.

Preoperative Weight Loss as a Predictor of Short and Midterm Postoperative Weight Loss in Patients Undergoing Bariatric Surgery.

Objective: To examine if preoperative weight loss correlates to postoperative weight loss 2 and 3 years after surgery. Methods: A review was conducted of bariatric surgery patients who underwent either gastric bypass or sleeve gastrectomy during 2015-2018 and had 3-year follow-up data. Demographic and outcome data were collected. A best-fit regression model for weight loss was constructed. Results: Eight hundred fifty-nine patients underwent surgery during the selected period, of which 199 patients (23%) were analyzed. Eighty-two percent of patients had gastric bypass and 82% were female. Preoperative percent excess weight loss (%EWL) was not significantly associated with 2- and 3-year postoperative %EWL (p = 0.18). Patients demonstrated significant weight regain at 3 years postoperatively versus 1 year (p < 0.01). Higher preoperative weight loss was associated with lower %EWL 3 years postoperatively versus 1 year (p = 0.04). Postoperative %EWL had a significant negative association with higher preoperative weight, diabetes, baseline use of a mobility device, and sleeve gastrectomy. Conclusions: In a cohort of bariatric surgery patients, there was no statistically significant association between preoperative and midterm postoperative %EWL. Postoperative %EWL was negatively associated with several patient-specific factors and increasing time since operation.

Preoperative and early adjuvant weight loss medications in bariatric surgery patients with body mass index over 60 or suboptimal initial response to surgery.

BACKGROUND: Few studies have examined the adjuvant use of antiobesity medications with surgery, especially in the pre- and early postoperative periods. OBJECTIVE: Evaluate the impact of adjuvant pharmacotherapy on bariatric surgery outcomes. SETTING: University hospital, United States. METHODS: A retrospective chart review of patients receiving adjuvant pharmacotherapy for obesity treatment and bariatric surgery. Patients received pharmacotherapy either preoperatively if their body mass index was >60, or in the first or second postoperative years for suboptimal weight loss. Outcome measures included percentage of total body weight loss as well as comparison with the expected weight loss curve as determined by the Metabolic and Bariatric Surgery Risk/Benefit Calculator. RESULTS: A total of 98 patients were included in the study, with 93 (94.9%) undergoing sleeve gastrectomy and 5 (5.1%) undergoing Roux-en-Y gastric bypass surgery. During the study period, patients were prescribed phentermine and/or topiramate. At postoperative year 1, patients who received pharmacotherapy preoperatively lost 31.3% of their total body weight (TBW) compared with 25.3% TBW for patients with suboptimal weight loss who received medication in the first postoperative year, and 20.8% TBW for patients who did not receive any antiobesity medication in the first postoperative year. Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) curve for comparison, patients receiving medication preoperatively weighed 2.4% less than expected, whereas patients receiving medication during the first postoperative year weighed 4.8% higher than expected. CONCLUSION: For patients having bariatric surgery who fall below the expected MBSAQIP weight loss curve, early initiation of antiobesity medications can improve the weight loss, with preoperative pharmacotherapy having the greatest effect.

The Roles of Depression and Binge Eating in the Relationship Between Adverse Childhood Experiences (ACEs) and Obesity.

OBJECTIVE: Research has demonstrated that adverse childhood experiences (ACEs) were related to elevated lifetime risk of developing obesity, but the underlying mechanisms between ACEs and development of obesity are yet to be fully elucidated. The current study aims to extend exiting evidence on underlying mechanisms between ACEs and development of obesity by examining whether depressive symptom and binge eating symptom have independently significant mediating effects on the association. METHODS: The study used data from a total of 473 patients seeking bariatric surgery who completed psychological evaluation including ACEs, depressive symptom, and binge eating scale as a part of presurgical multidisciplinary weight management consultations. Mediation analyses were conducted using the PROCESS macro for SPSS to examine the research objective. RESULTS: The study found that depressive symptom uniquely mediated the relationship between ACEs and obesity, but binge eating symptom did not significantly mediate the relationship independently of depression. CONCLUSIONS: The unique role of depression in relation to childhood trauma in this study argues for more focus on a mental health intervention with bariatric patients during the preoperative period. Addressing ACEs for bariatric patients who present psychiatric symptoms during preoperative process could have potential benefits to patient care.

Metabolic bone disease and fracture risk after gastric bypass and sleeve gastrectomy: comparative analysis of a multi-institutional research network.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the two most performed bariatric procedures. Multiple studies have investigated the metabolic bone complications after bariatric surgery, but there is a paucity of data comparing bone health after RYGB and SG. OBJECTIVES: To compare the rates of major fractures and osteoporosis after Roux-en-Y gastric bypass and sleeve gastrectomy. SETTING: Data from TriNetX multi-institutional research network that includes data from multiple health care organizations in the USA was analyzed at West Virginia University. METHODS: We conducted a retrospective cohort study using TriNetX, a federated multi-institutional research network. We identified patients who underwent RYGB or SG. Primary outcome was the rate of major fractures at 3 years after the procedure. Other outcomes included the rate of spine fracture, femur fracture, osteoporosis, and vitamin D deficiency at follow-up. RESULTS: In unmatched analysis, patients with SG were less likely to have major fractures or an osteoporosis diagnosis than RYGB patients at 3 years after the procedure (P < .05). After propensity-score matching, similar results were noted; patients with SG were less likely to have major fractures than RYGB patients at 3 years after procedure (2.85% versus 3.66%, risk ratio [RR]: .78, 95% confidence interval [CI]: .71-.85), and a lower rate of osteoporosis diagnosis was noted in the SG group. High rates of vitamin D deficiency were noted in both cohorts. The incidence of spine fractures was significantly lower in the SG group than in the RYGB group (.76% versus 1.18%, RR: .65, 95% CI: .54-.77). Similarly, the incidence of femur fracture was significantly lower after SG (RR: .62, 95% CI: .44-.88). Female sex, higher age, smoking history, and diabetes were independently associated with osteoporosis diagnosis during follow-up (all P values <.05). CONCLUSION: Our analyses showed that RYGB is associated with a higher risk of osteoporosis, vitamin D deficiency, and osteoporotic fractures. Thus, in patients with a higher baseline osteoporotic risk, SG may be preferred option; however, further studies are needed.

Prior Bariatric Surgery is Associated with a Reduced Risk of Poor Outcomes in COVID-19: Propensity Matched Analysis of a Large Multi-institutional Research Network.

PURPOSE: Through sustained weight loss and improvement in metabolic co-morbidities, bariatric surgery is hypothesized to reduce the risk of severe COVID-19. Small studies have suggested favorable outcomes; however, large population-based studies are lacking. MATERIALS AND METHODS: We conducted a retrospective cohort study utilizing the multi-institutional research network TriNeTx platform. Participants diagnosed with COVID-19 were identified and divided into cohorts based on prior bariatric surgery (BS). Primary study outcome was a composite event of death or requirement for mechanical ventilation up to 30-day following the diagnosis of COVID-19. Other outcomes included death, hospitalization, critical care need, and acute kidney injury in the 30-day follow-up period. Outcomes were compared in BS and non-BS cohorts after propensity score matching. RESULTS: There were significant differences in patient demographics and co-morbidities between the BS and non-BS groups. In the propensity score-matched analysis, there was a lower risk of reaching the primary endpoint of mechanical ventilation or mortality at 30 days after COVID-19 diagnosis in the BS cohort compared to the non-BS cohort (risk ratio (RR) 0.40, 95% CI 0.25-0.65). Mortality rate was lower in the BS cohort (RR 0.42, 95% CI 0.22-0.80), and patients in the BS group were less likely to require critical care (RR 0.54, 95% CI 0.38-0.77), mechanical ventilation (RR 0.43, 95% CI 0.24-0.78) or develop acute kidney injury (RR 0.57, 95% CI 0.43-0.76) after COVID-19 diagnosis. CONCLUSION: Prior bariatric surgery is associated with a reduced risk of poor outcomes of COVID-19. Furthermore, large prospective studies are needed.

The role of body appreciation, weight bias internalization, and disordered eating behaviors among presurgical bariatric patients.

BACKGROUND: Body appreciation and internalized weight bias have consistently been associated with eating behaviors. However, research has yet to examine the role of these variables among presurgical bariatric patients. OBJECTIVES: The present study sought to assess the relationships between body appreciation and weight bias internalization, binge eating, disinhibited eating, and symptoms of depression and anxiety among a sample of presurgical bariatric patients. The study also sought to examine the extent to which body appreciation and weight bias internalization account for unique variance in disordered eating even when controlling for depression and anxiety. SETTING: Academic medical center in the United States. METHODS: Data were collected on body appreciation, weight bias internalization, eating behaviors, depression, and anxiety as part of a standard presurgical psychological evaluation for bariatric surgery (n = 319). Pearson correlations were used to assess relationships between all study variables. Multiple regressions were conducted to assess the roles of body appreciation and weight bias internalization on disordered eating. RESULTS: Significant associations were found between low levels of body appreciation and high levels of weight bias internalization, disordered eating, and symptoms of depression and anxiety. Results indicated that body appreciation and weight bias internalization each significantly accounted for unique variance in symptoms of binge eating and disinhibited eating. Depressive symptoms were also statistically significant in all analyses. CONCLUSION: Findings indicate the importance of conducting future positive body image research, as well as continuing to examine weight-related constructs, such as internalized weight bias, among bariatric surgery patients.

Disinhibition and Subjective Hunger as Mediators Between Weight Bias Internalization and Binge Eating Among Pre-Surgical Bariatric Patients.

PURPOSE: Weight bias internalization, or the process of applying negative weight-related attitudes and beliefs to oneself, is an important construct in regard to patients pursuing bariatric surgery. Weight bias internalization (or internalized weight bias) has been previously associated with depressive symptoms and binge eating among pre-surgical bariatric patients. However, a gap in the literature exists pertaining to how certain eating behaviors may mediate the relationship between weight bias internalization and binge eating. The present study assessed the role of eating behaviors (i.e., cognitive restraint, disinhibition, and hunger) as mediators between weight bias internalization and binge eating symptoms when controlling for depression. MATERIALS AND METHODS: A total of 708 adults (Mage = 42.91; White = 95.3%; women = 79.4%) seeking bariatric surgery at a tertiary academic medical center in the Appalachia region of the USA were included in this retrospective study. Patients completed validated measures of weight bias internalization, eating behaviors, and depression as part of a routine, psychological evaluation in order to determine surgical clearance. RESULTS: Disinhibition and hunger were significant mediators in the relationship between weight bias internalization and binge eating beyond the role of depressive symptoms alone. CONCLUSION: Disinhibited eating, or the tendency to experience a loss of control and eating in response to negative emotions, as well as subjective feelings of hunger are important dimensions of eating, particularly as related to weight bias internalization and binge eating. Weight bias internalization is an important factor to consider among pre-surgical bariatric patients and warrants additional treatment considerations.

The use of an activity tracker to objectively measure inpatient activity after bariatric surgery.

BACKGROUND: Early postoperative ambulation reduces length of stay and prevents postoperative complications after bariatric surgery. Rarely is postoperative inpatient activity objectively measured despite readily available commercial activity trackers. OBJECTIVES: Evaluate the impact of using activity trackers to record number of inpatient steps taken after bariatric surgery and assess how patient characteristics may affect the number of steps recorded. SETTING: University Hospital, United States. METHODS: Using an activity tracker, the number of steps taken during the postoperative hospital stay was recorded for 235 patients undergoing either laparoscopic Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy. Patients were randomly assigned to either being informed about the devices' ability to record the number of steps taken or blinded to the purpose of the devices. Descriptive statistics were used to summarize study sample, a t test was used to compare number of steps recorded between groups, and a multivariate regression model was used to examine the effect of age, sex, preoperative body mass index (BMI), types of surgery, and length of stay on number of steps recorded. RESULTS: One hundred twenty-five patients (52.8%) were randomized to the blinded group while 111 (47.2%) were informed that the device would record the number of steps taken. There were no differences in the number of steps recorded between the 2 groups. Patients with prolonged length of stay recorded lower numbers of steps taken on postoperative day 0. Increasing age was seen to reduce the number of steps recorded on postoperative day number 1. There were no significant differences in number of steps recorded based on sex, preoperative BMI, or surgery type. CONCLUSION: The present study found that knowledge of an activity tracker being used did not affect the patient's activity level as measured by steps recorded. Increasing age correlated to reduced number of steps recorded on postoperative day 1 after bariatric surgery.

Sexual minority bariatric patients: preliminary examination of eating behaviors, anxiety, and depression.

BACKGROUND: Disparities in obesity care and bariatric surgery persist among patients of diverse identities. However, little is known about sexual minority (SM) bariatric patients. OBJECTIVES: This study sought to describe, in a preliminary fashion, sexual orientation variables of outness, self-esteem, and perceived discrimination among a sample of SM patients pursuing bariatric surgery. The study also sought to compare SM and heterosexual bariatric candidates on measures of eating behaviors, anxiety, and depression. SETTING: Academic medical center in the United States. METHODS: Data were collected as part of a standard psychological evaluation for surgical clearance between May 1, 2018 and December 31, 2019. Data included demographic characteristics, sexual orientation variables, eating behaviors, anxiety, and depression. Descriptive statistics were included to present findings among SM patients. One-way analyses of covariance were conducted to assess differences between SM and heterosexual patients. RESULTS: A total of 633 patients were evaluated (38 SM and 595 heterosexual). SM patients had high outness scores with high self-esteem and minimal perceived discrimination. SM patients endorsed lower cognitive restraint, higher disinhibition, and increased hunger compared with heterosexual patients (P < .05). SM patients also reported significantly more symptoms of anxiety and depression compared with heterosexual patients (P < .05). CONCLUSIONS: Findings provide preliminary evidence toward the importance of assessing for sexual orientation among bariatric patients. Future research is warranted to assess the unique role of sexual orientation, as well as explore causal links between sexual orientation, eating behaviors, and mental health among bariatric patients pre- and post surgery.

Emergency Laparoscopic Repair of an Iatrogenic Gastric Perforation in a Hiatal Hernia following a Failed Endoscopic Closure.

Iatrogenic gastrointestinal perforation is a rare, life-threatening complication of endoscopic procedures, which requires either endoscopic or surgical repair. We report the account of an 82-year-old woman with an iatrogenic gastric perforation of a hiatal hernia secondary to an endoscopic retrograde cholangiopancreatography (ERCP) procedure. Despite immediate recognition of the complication and endoscopic closure with through-the-scope (TTS) clips, the patient developed mediastinitis, peritonitis, and sepsis. She subsequently underwent an emergency laparoscopic hiatal hernia dissection and repair of the perforation with mediastinal and peritoneal washout. Given the patient's age and the degree of insult, subdiaphragmatic anchoring with abdominal drain placement was performed, and the hiatus was left open for additional drainage. The use of a side-viewing duodenoscope with the presence of a large hiatal hernia contributed to the risk of gastric perforation. We conclude that performing endoscopic procedures in patients with a known hiatal hernia should be carefully undertaken. If a perforation in such patients occurs, laparoscopic repair of such complications is feasible as demonstrated in this case video.

Psychological Diagnoses and Weight Loss among Appalachian Bariatric Surgery Patients.

Background: The relationship between presurgical psychopathology and weight loss following bariatric surgery is complex; previous research has yielded mixed results. The current study investigates the relationship among presurgical mental health diagnoses, symptom severity, and weight loss outcomes in an Appalachian population, where obesity-related comorbidities are prominent. Methods: A retrospective chart review was performed on bariatric surgery patients in an accredited Appalachian centered academic hospital in northern West Virginia between 2013 and 2015 (n = 347). Data extraction included basic demographics, anthropometrics (percent excess weight loss (%EWL)) at six-month, one-year, and two-year postoperative visits, and two validated psychological questionnaires (Beck Depression Inventory (BDI-II) and Beck Anxiety Inventory (BAI)) from patient's presurgical psychological evaluation. Results: Average patient population was 92.5% Caucasian, 81.5% female, 45 ± 11.5 years old, and 84.1% who underwent laparoscopic Roux-en-Y gastric bypass surgery with the remaining having laparoscopic sleeve gastrectomy. At baseline, no differences were detected in weight, excess body weight, or body mass index between surgery types. Average baseline BDI-II score was 10.1 ± 8.68 (range 0-41) and BAI score was 6.1 ± 6.7 (range 0-36), and this was not significantly different by surgery at baseline. Both baseline psychological scores were in the "minimal" severity range. BDI-II was positively related to BMI of patients at baseline (p = 0.01). Both BDI-II and BAI were not significantly related to %EWL across follow-up. Conclusion: Other than baseline weight, BDI-II and BAI scores were not related to %EWL outcomes in patients receiving bariatric surgery in the Appalachian region. Future work should examine mixed methods approaches to capture prospective and longitudinal data to more thoroughly delve into mental health aspects of our Appalachian patients and improve efforts to recapture postoperative patients who may have been lost to follow-up.

Laparoscopic Removal of Angelchik Prosthesis Followed by Interval Sleeve Gastrectomy.

INTRODUCTION: The Angelchik prosthesis (AP) is a historic antireflux device which consists of a C-shaped silicone ring placed around the gastroesophageal junction (GEJ) and secured by Dacron tape. We present a rare experience with an AP and its impact on bariatric surgical outcomes. CASE: Our patient is a 66-year-old woman who had an open antireflux procedure with an AP in 1987. She presented to a bariatric clinic for consideration of bariatric surgery for the treatment of morbid obesity and associated comorbidities. She also reported significant problems with reflux and dysphagia. After an appropriate work-up, an AP was identified at her GEJ. She was taken to the operating room for laparoscopic removal with planned interval laparoscopic sleeve gastrectomy. Intraoperatively, the AP was identified around the GEJ; after extensive adhesiolysis, the prosthesis was removed. Postoperatively, in order to determine if the AP had caused any lasting esophageal motility problems, the patient underwent a high-resolution esophageal manometry which demonstrated normal esophageal motility. Interval laparoscopic sleeve gastrectomy was performed safely 9 weeks later. CONCLUSION: Although rarely used, it is still possible to encounter an Angelchik prosthesis in practice. General and bariatric surgeons need to be aware of this rare device and understand how to manage its related complications.

A randomized control trial using intraoperative dexmedetomidine during Roux-en-Y gastric bypass surgery to reduce postoperative pain and narcotic use.

BACKGROUND: Dexmedetomidine (DMET), a selective a2-adrenergic agonist, is an opioid-sparing adjuvant sedative that avoids respiratory depression and has been shown to be beneficial in bariatric surgery patients. Although benefit has been shown, prior studies have not evaluated the pain control effects of a single intraoperative bolus. OBJECTIVES: To evaluate the postoperative effects of a single intraoperative dose of DMET. SETTINGS: University Hospital, United States. METHODS: This is a prospective, randomized, double-blinded study registered with clinicaltrials.gov (#NCT02604940). Patients undergoing laparoscopic Roux-en-Y gastric bypass surgery were randomized and given either a placebo or an intraoperative DMET bolus, where 1 mg/kg was delivered over 10 minutes at the time of surgical closure. Measured outcomes included the following: postoperative pain scores, patient-controlled analgesia (PCA) opioid consumption, PCA demand bolus attempts, duration of postanesthesia care unit (PACU) stay, and vital signs. Descriptive statistics were recorded as frequencies and compared using Χ2 analysis, and a Welch's 2-sample t test was used to compare continuous variables. RESULTS: Forty-six participants undergoing laparoscopic Roux-en-Y gastric bypass surgery were randomized into placebo (n = 20) or DMET (n = 26) groups. There were no statistical differences in age (45.1 versus 43.2 yr, P = .522), sex (80% versus 81% female, P = .948), and body mass index (46.1 versus 45.6 kg/m2, P = .818) between the 2 groups. There were no statistically significant differences in vital signs (heart rate, blood pressure, oxygen saturation, and respiration rate) between DMET and placebo groups in the preoperative and intraoperative period. During the initial 4 hours in the PACU postoperatively, mean heart rate (70 ± 12 versus 86 ± 14, P < .001), systolic blood pressure (107 ± 17 versus 148 ± 16, P < .001), and diastolic blood pressure (56 ± 15 versus 79 ± 13, P < .001) were significantly lower in the DMET-treated group compared with placebo. During the initial 4 hours in the PACU, mean self-reported pain scores were significantly lower in the DMET-treated group (3.6 ± 2.8) compared with the placebo group (6.7 ± 3; P = .005). The lower pain scores occurred with no significant difference in the mean opioid dosage received in the PACU between DMET-treated (2.66 ± 2.02 mg) and placebo (3.7 ± 2.3 mg; P = .09) groups. Also, there was no statistically significant difference in the total number of PCA attempts for opioids between the DMET-treated and placebo groups (P = .49). CONCLUSIONS: A single bolus of DMET (1 mg/kg delivered over 10 min) administered at the time of surgical closure did not reduce immediate PACU usage of opioids but significantly reduced reported pain scores and caused a significant decrease in the number of attempts made by patients; this is a trend of decreased attempts over time (P = .04) in the DMET group. The trend of the mean total medication used over time indicates that there is neither an increasing nor decreasing trend for the DMET group, but there is an increasing trend in the total used over time for the placebo group. There was no statistically or clinically significant bradycardia, hypotension, hypoxia, respiratory depression intraoperative duration, or PACU stay. Reduced single bolus dosing of DMET required for analgesia in bariatric surgery patients is optimal from physiologic, level of care, and cost perspectives.

Bariatric Surgery Outcomes in Appalachia Influenced by Surgery Type, Diabetes, and Depression.

BACKGROUND: Most effective treatment for morbid obesity and its comorbidities is bariatric surgery. However, research is limited on weight loss and associated outcomes among patients in Appalachia. The objective of this study was to examine demographic and comorbidity influence on surgical outcomes of this population including age, sex, race, state of residence, education, marital status, body mass index (BMI kg/m2), excess body weight (EBW), percent excess weight loss (%EWL), blood pressure, diagnosed depression, diagnosed type 2 diabetes (T2D), Beck Depression Inventory-II (BDI-II), and laboratory values (i.e., hemoglobin A1c). METHODS: A retrospective electronic medical record (EMR) data extraction was performed on N = 582 patients receiving bariatric surgery (laparoscopic Roux-en-Y gastric bypass [RYGB] and laparoscopic sleeve gastrectomy [SG]) between 10/2013 and 2/2017. RESULTS: Patient population was 92.5% Caucasian, 79.3% female, 62.8% married, 45 ± 11.1 years, 75.8% received RYGB, and 24.2% received SG. Average %EWL from baseline to 1-year follow-up was 68.5 ± 18.4% (n = 224). In final descriptive models, surgery type, diagnosed T2D, HbA1c, and depressive symptoms were significant covariates associated with lower %EWL. CONCLUSIONS: Findings suggest patients completing surgery within an Appalachian region have successful surgical outcomes at 1-year post-surgery, as indicated by significant reductions of > 50% EWL, regardless of other covariates. Results suggest that bariatric programs should consider paying special consideration to patients with T2D or depressive symptoms to improve outcomes. Results have potential to inform future prospective studies and aid in guiding specific interventions tailored to address needs of this unique population.
