RESUMO
PURPOSE: To evaluate the impact of an inpatient pharmacy consult on discharge medications following bariatric surgery. METHODS: A pharmacy consult for discharge medication review for bariatric surgery patients was instituted at an academic medical center. The intervention included conducting a medication history, reviewing home medications for updates post-bariatric surgery, creating and documenting a discharge medication plan, and providing patient education. The impact of the intervention was evaluated by comparing medication classes, doses, and formulations prescribed during the intervention relative to a historical control group. RESULTS: The study included 85 patients who received pharmacist intervention and 167 patients who did not receive pharmacist intervention following bariatric surgery. The prescription of an extended-release medication at discharge in the intervention group was reduced by 19.3% (28.7% vs. 9.4%, p = 0.0005). For patients on hypertension medications, 94.0% had their regimen reduced in the intervention group compared with 37.5% of patients in the control group (p < 0.001). Of patients on insulin at baseline, 87.5% of patients in the intervention group had dose reductions at discharge vs. 66.7% of patients in the control group (p = 0.37). No patients in the intervention group were discharged with oral antihyperglycemic medications or non-insulin injectable medications vs. 33.3% (p = 0.12) and 20.0% (p = 0.47), respectively, in the control group. Readmission rates at 30 days were insignificantly lower in the intervention group (3.5% vs. 4.2%, p = 1). CONCLUSIONS: Clinical pharmacist involvement in the discharge medication reconciliation process for bariatric surgery patients reduced prescribing of unadjusted medication classes, doses, and drug formulations.

BACKGROUND: Multiple medication changes are common after bariatric surgery, but pharmacist assistance in this setting is not well described. This study evaluated the feasibility and effectiveness of a pharmacy-led initiative for facilitating discharge medicine reconciliation after bariatric surgery. METHODS: A standardized post-operative pharmacy consult evaluation was conducted on bariatric surgery inpatients at a single academic center starting 1/2/2019. Retrospective chart review evaluated patient characteristics, medication changes, and 30-day outcomes pre-intervention (7/2018-12/2018) and post-intervention (1/2019-12/2019). Two-sample t tests or binomial tests were used for continuous or categorical variables, respectively; a p-value of < 0.05 was deemed statistically significant. RESULTS: A total of 353 patients were identified for study inclusion (n = 158 pre-intervention, n = 195 post-intervention) with a mean age of 45 years, 87% female, and 71% sleeve gastrectomy. Overall pharmacy consultation compliance was 94% with 77.0% of home medication recommendations followed. Non-narcotic pain medication prescription use significantly increased (39% pre- vs. 54% post-intervention; p < 0.001). At discharge, the average number of changed or new medications significantly increased (3.7 ± 1.2 pre- vs. 4.2 ± 1.8 post-intervention; p = 0.003) while the average number of stopped medications was similar (1.2 ± 1.5 pre- vs. 1.5 ± 1.9 post-intervention; p = 0.09). Anti-hypertensive medications were decreased or stopped substantially more often with pharmacist input (44.7% pre- vs. 85.4% post-intervention; p < 0.001). Three medication-related readmissions happened pre-intervention with none post-intervention. Outpatient medication-related phone calls did considerably increase (31% pre- vs. 39% post-intervention; p = 0.04), while overall 30-day readmissions significantly decreased (7.6% pre- vs. 1.5% post-intervention; p = 0.04). CONCLUSIONS: Inpatient pharmacy consultation facilitated rapid alteration to more appropriate therapy for hypertension management and significantly increased use of non-narcotic pain medications upon discharge among bariatric surgery patients. Improved protocol adherence is anticipated with program maturity and patient education interventions will be deployed to address outpatient phone calls.

BACKGROUND: Obesity has been associated with cognitive deficits and increased risk for developing dementia. Bariatric surgery may result in improved cognitive function; however, the underlying structural and functional brain correlates are unclear. OBJECTIVES: This longitudinal study explores the hypothesis that specific brain regions and networks underlie cognitive changes after bariatric surgery. SETTING: University Hospital, United States. METHODS: Seventeen patients were recruited for this prospective cohort study, including 9 patients undergoing bariatric surgery, and 8 age-, sex-, and education level-matched healthy, nonobese control patients. Bariatric patients underwent longitudinal neuropsychologic tests and magnetic resonance imaging (MRI) scans both before and 6 months after surgery. One patient was lost to follow-up. The same neuropsychologic tests and MRI scans were performed for control patients. Differences in MRI and neuropsychologic testing between bariatric patients and control patients, and longitudinal changes within bariatric patients were assessed. RESULTS: At baseline, bariatric patients demonstrated deficits in cognitive function relative to control patients, including pattern comparison (P = .009) and picture sequence memory (P = .004), which improved after significant weight loss. Baseline cognitive deficits in bariatric patients were accompanied by significantly lower left executive control network connectivity on resting-state functional MRI relative to control patients (P = .028), but differences resolved or diminished after bariatric surgery. Longitudinal improvements in pattern comparison performance correlated significantly with increases in left executive control network connectivity (r = .819; P = .013). No significant group or longitudinal differences were found in brain perfusion or brain white matter lesions. CONCLUSIONS: Individuals with obesity undergoing bariatric surgery exhibit deficits in cognitive function and specific alterations of brain networks; however, cognitive performance can improve, and executive control network connectivity can increase after weight loss from bariatric surgery.

OBJECTIVE: This study evaluated the safety of percutaneous CT-guided cryoablation of the vagus nerve (percutaneous cryovagotomy) in participants with class I or class II obesity. METHODS: The study was an open-label, single-group, prospective pilot investigation designed around safety-related stopping criteria. Twenty participants with 30 > BMI > 37 underwent percutaneous cryovagotomy with follow-up visits at day 7, 45, 90, and 180. Data related to adverse events, technical success, weight loss, quality of life, dietary intake, global impressions of hunger change, activity, and body composition were analyzed. RESULTS: The procedural technical success rate was 100%. There were no adverse events in 19 participants who completed the trial. Ninety-five percent of patients reported decreased appetite following the procedure, and reductions in mean absolute weight and BMI were observed at all time points. The mean quality of life and activity scores improved from baseline to 6 months post procedure, and mean caloric intake and overall body fat decreased over the same period. CONCLUSIONS: Percutaneous CT-guided cryovagotomy is feasible and was tolerated without complications or adverse events in this cohort. Quantitative preliminary data from this pilot investigation inform the design of a larger prospective randomized clinical trial.

Polycystic ovary syndrome (PCOS) is a common disease among the bariatric population. However, there are limited data regarding the impact of laparoscopic sleeve gastrectomy (SG) on these patients. The study was conducted at University Hospital, United States. The purpose of this study was to examine per cent excess body weight loss (%EWL) and diabetes control in patients who have PCOS compared with those without PCOS. A total of 550 female patients underwent SG between December 2011 and October 2016. Retrospective analysis was completed to include follow-up data at 1, 3, 6, and 12 months and yearly after that. Outcomes measured were %EWL and hemoglobin A1c (HgbA1c). The mean and median follow-up for the entire cohort was 21 and 15 months, respectively. Seventy-eight per cent of patients completed at least 12 months of follow-up for %EWL, although only 21 per cent had similar follow-up for HgbA1c. PCOS patients had similar age (36.3 vs 36.2 years, P = 0.90), preoperative BMI (47.2 vs 47.2, P = 0.99), preoperative HgbA1c (6% vs 5.8%, P = 0.31), conversion rate to gastric bypass, and other associated comorbidities compared with non-PCOS comparisons. There was no difference in %EWL at 12-month (49.7% vs 53.1%, P = 0.53) or 24-month (43% vs 49.8%, P = 0.46) postoperative intervals. There was no difference in absolute change of HgbA1c at 12 months (-0.47% vs -0.67%, P = 0.39). SG has equivalent short-term results in %EWL and reduction in HgbA1c for patients who have PCOS and those who do not.

BACKGROUND: Enhanced Recovery after Surgery (ERAS) protocols lead to expedited discharges and decreased cost. Bariatric centers have adopted such programs for safely discharging patients after sleeve gastrectomy (LSG) on the first postoperative day (POD1). Despite pathways, some bariatric patients cannot be discharged on POD1. STUDY DESIGN: We performed a retrospective review of patients undergoing LSG, from 2013 through 2016, in a center of excellence, using a standardized enhanced recovery pathway. Patient variables and perioperative factors were analyzed, including multivariate regressions, for predictors of early discharge. RESULTS: There were 573 patients who underwent LSG (83% female, mean age of 46.3 ± 11.7 years, and BMI of 46.0 ± 6.6 kg/m2). Mean hospital stay was 1.7 days ± 1.0 SD. Early discharge occurred in 38.2% of patients. Independently, early operating room start times and treated obstructive sleep apnea were associated with earlier discharge (p < 0.05). In contrast, preoperative opioid use, history of psychiatric illness, chronic kidney disease, and revision cases delayed discharge (p < 0.05). Age, sex, American Society of Anesthesiologists (ASA) class, diabetes, congestive heart failure, hypertension, distance to home, and insurance status were not significant. On regression modeling, early operating room start time and treated obstructive sleep apnea (OSA) reduced length of stay (LOS) (p < 0.05), while creatinine >1.5 mg/dL, ejection fraction < 50%, and increased case duration increased LOS (p < 0.05). Fifteen patients were readmitted within 30 days (2.6%). CONCLUSIONS: Several clinical and operative factors affect early discharge after LSG. Knowing factors that enhance the success of ERAS as well as the causes and corrections for failed implementation allow teams to optimally direct care pathway resources.

BACKGROUND: Restrictive bariatric procedures reduce gastric capacity as a primary mechanism of action. Intraoperatively, surgeons observe variability in size and compliance of specimens. We hypothesized that higher gastric specimen volume or tissue compliance would respond better to restrictive procedures. MATERIALS AND METHODS: Consecutive patients undergoing laparoscopic sleeve gastrectomy between September 2012 and September 2013 were enrolled. Specimens were insufflated at graduated pressure points creating pressure volume curves, and compliance was calculated. Postoperative weight loss and a hunger scores were recorded. Correlations were determined by Spearman correlation. RESULTS: Eighty-four patients consented to enrollment. Mean age, weight, and body mass index (BMI) were 45 ± 12 years, 126 ± 23 kg, and 45.4 ± 6 m/kg2, respectively. The resected specimens varied in insufflated capacity from 0.3 to 1.8 (0.71 ± 0.32) L and compliance varied from 14.3 to 85.7 (36.1 ± 14.7) cc/mm Hg. Male patients had a larger greater curvature length (GCL) (P < 0.001), staple line length (SLL) (P = 0.03), gastric volume (GV) (P = 0.002), and gastric compliance (GC) (P < 0.001). Neither GV nor GC correlated to excess body weight loss (EBWL%) as hypothesized. There was an inverse correlation between hunger score and GV (P = 0.010). The mean 1-month, 3-month, 6-month, and 12-month EBWL was 17.4%, 33.2%, 43.7%, and 54.1%, respectively. Follow-up was 71.4% at 1 month, 39.3% at 3 months, 54.8% at 6 months, and 42.9% at 12 months. CONCLUSIONS: Sleeve gastrectomy specimens exhibit nearly 6-fold variability in both volume and compliance. A large GC is anticipated in male and tall subjects. These observations do not appear to be correlated to %EBWL.

BACKGROUND: Surgical treatment for giant paraesophageal hernias (PEH) in morbidly obese patients (BMI > 35) continues to be a difficult problem. Prior studies have demonstrated recurrence rates of up to 40% with higher rates in morbidly obese patients. Reports have shown success combining repair with a bariatric procedure to decrease recurrence rates while achieving weight loss. We report mid-term results from a larger series with combining laparoscopic giant PEH repair with sleeve gastrectomy (SG). METHODS: We reviewed all combined cases of PEH repairs with SG done at a single institution from 2008 to 2013. The surgical technique was standardized and absorbable bio-prosthetic buttress crural closure reinforcement was used selectively. Yearly upper gastrointestinal radiographic (UGI) studies and postoperative Gastroesophageal Reflux Disease Health-Related Quality of Life questionnaires were completed. 33 patients were enrolled; 18 patients (55%) completed the study RESULTS: No 30-day morbidity or mortality occurred. 16 patients were female; the average age was 55.3 ± 11.4 years (30-72) with follow-up from surgery of 19.9 ± 16.7 months (6-66). The average weight loss was 23.5 ± 12.7 kg (8-57); excess body weight loss was 46 ± 25.8% (18-112). Based on the UGIs, 9/18 (50%) had no evidence of hernia recurrence, while 6/18 (33%) demonstrated a small (<2 cm) recurrence. 3/18 (17%) patients had evidence of moderate recurrence (3-5 cm). Postoperative GERD-HRQL scores revealed an average score of 10 ± 7 (2-26). All patients reported being "satisfied" with their operation and weight loss and also had a significant improvement in foregut symptoms. No patient has required surgical revision and residual symptoms responded to conservative management. CONCLUSIONS: PEH in morbidly obese patients remain a complex surgical problem. Our case series shows that combination with SG may decrease recurrence rates but more importantly leads to lower rates of reoperation for symptomatic recurrence. Patients also garner the added medical benefits of weight loss.
