RESUMO
BACKGROUND: Aborted bariatric surgeries are an undesirable experience for patients as they are subjected to potential physical harm and emotional distress. A thorough investigation of aborted bariatric surgeries has not been previously reported. This information may allow the discovery of opportunities to mitigate the risk of aborting some bariatric operations. METHODS: Data from the Michigan Bariatric Surgery Collaborative, a statewide bariatric surgery registry, were used to identify all aborted primary bariatric operations from June 2006 through January 2023. The reasons for aborting surgery were divided into seven categories. Stepwise logistic regression was performed to identify independent predictors of aborted procedures for potentially modifiable factors. RESULTS: A total of 115,004 patients underwent bariatric surgery with 555 (0.48%) procedures aborted. Of those having an aborted operation the mean age was 52 years and mean BMI was 49.8 with females accounting for 72%. Sleeve gastrectomy had the lowest aborted rate (0.38%) as compared to gastric bypass, adjustable gastric banding, and biliopancreatic diversion (p < 0.0001). The most common aborted surgery reason categories included adhesions and hernias, tumors and anatomic anomalies, and inadequate visualization due to either hepatomegaly or abdominal wall thickness. The most significant (p < 0.0001) independent predictors of aborted surgeries due to hepatomegaly or abdominal wall thickness were BMI ≥ 60 (OR 10.7), BMI 50 to 59 (OR 3.1) and diabetes mellitus (OR 2.7). Preoperative weight loss was a protective factor for aborting surgery due to hepatomegaly or abdominal wall thickness (OR 0.9; p < 0.0001). CONCLUSIONS: Aborted surgeries are uncommon and occur in approximately 1 in 200 primary bariatric operations with the lowest rate identified in sleeve gastrectomy. Nearly 20% of operations are aborted due to hepatomegaly or abdominal wall thickness and targeting patients with elevated BMIs and diabetes mellitus for preoperative weight loss might reduce the risk of these types of aborted procedures.
RESUMO
INTRODUCTION: Sex as a biologic variable remains largely understudied, even for the most commonly performed operations. The most effective treatment for obesity and obesity-associated comorbidities is bariatric surgery. There are limited data to describe potential differences in outcomes between male and female patients, particularly with regards to weight loss. Within this context, we examined weight loss and complications up to 1 y following sleeve gastrectomy or gastric bypass within a statewide bariatric quality improvement collaborative. METHODS: We performed a retrospective cohort study among patients who had bariatric surgery. Using a state-wide bariatric-specific data registry, all patients who underwent gastric bypass or sleeve gastrectomy between June 2006 and June 2022 were identified. The primary outcome was percent excess body weight loss and change in body mass index (BMI) at 1 y. The secondary outcome was 30-d risk-adjusted complications. RESULTS: Among 107,504 patients, the majority (n = 85,135; 79.2%) were female and most patients (n = 49,731; 58%) underwent sleeve gastrectomy. Compared to female patients, male patients were older (47.6 y versus 44.8 y; P < 0.0001), had higher baseline weight (346.6 lbs versus 279.9 lbs; P < 0.0001), had higher preoperative BMI (49.9 kg/m2versus 47.2 kg/m2; P < 0.0001), and higher prevalence of most comorbid conditions including hypertension, hyperlipidemia, diabetes, and sleep apnea (P < 0.0001). Compared to female patients, male patients experienced greater total body weight loss (105.1 lbs versus 84.9 lbs; P < 0.0001) and higher excess body weight loss (60.0% versus 58.8%; P < 0.0001) but had higher BMI overall (34.0 kg/m2versus 32.8 kg/m2; P < 0.0001) at 1-y follow-up. Males had higher rates of serious complications (2.5% versus 1.9%; P < 0.0001), leak and perforation (0.5% versus 0.4%; P < 0.0001), venous thromboembolism (0.7% versus 0.4%; P < 0.0001), and medical complications (1.5% versus 1%; P < 0.0001). CONCLUSIONS: In this study we found that both males and females experienced excellent weight loss with a low risk of complications following bariatric surgery. Male sex was associated with slightly greater weight loss and slightly higher incidence of complications. However, although statistically significant, clinically, the differences in weight loss was not. Due to males having higher prevalence of comorbidities, providers should consider referring males earlier for bariatric surgery which may improve outcomes for this population.

BACKGROUND: Sleeve gastrectomy (SG) is the most commonly performed weight loss operation, and its 2 most common complications are postoperative reflux and weight recurrence. There is limited evidence to guide decision-making in treating these conditions. OBJECTIVES: To determine the efficacy of conversion of SG to Roux-en-Y gastric bypass (RYGB) for GERD management and weight loss. SETTING: Forty-one hospitals in Michigan. METHODS: We conducted a retrospective cohort study examining patients who underwent conversion of SG to RYGB from 2014 to 2022. The primary outcomes were changes in GERD-HRQL scores, anti-reflux medication use, and weight from baseline to 1 year after conversion. Secondary outcomes included 30-day postoperative complications and resource utilization. RESULTS: Among 2133 patients undergoing conversion, 279 (13%) patients had baseline and 1-year GERD-HRQL survey data and anti-reflux medication data. GERD-HRQL scores decreased significantly from 24.6 to 6.6 (P < .01). Among these, 207 patients (74%) required anti-reflux medication at baseline, with only 76 patients (27%) requiring anti-reflux medication at 1 year postoperatively (P < .01). Of the 380 patients (18%) with weight loss data, mean weight decreased by 68.4lbs, with a 24.3% decline in total body weight and 51.5% decline in excess body weight. In terms of 30-day complications, 308 (14%) patients experienced any complication and 89 (4%) experienced a serious complication, but there were no leaks, perforations, or deaths. Three-hundred and fifty-five (17%) patients presented to the emergency department and 64 (3%) patients underwent reoperation. CONCLUSIONS: This study represents the largest reported experience with conversion from SG to RYGB. We found that conversion to RYGB is associated with significant improvement in GERD symptoms, reduction in anti-reflux medication use, and significant weight loss and is therefore an effective treatment for GERD and weight regain after SG. However, the risks and benefits of conversion surgery should be carefully considered, especially in patients with significant comorbidity burden.

BACKGROUND: Neglect of vaccination needs among adults results in a needless burden of hospitalization, suffering, and death. America's community pharmacists deliver a substantial portion of adult vaccinations, yet many Americans still have unmet vaccination needs. OBJECTIVES: This study evaluated rates of vaccine contraindications, acceptance, and willingness to be vaccinated among ambulatory adults. PRACTICE DESCRIPTION: This was a prospective, multisite, multistate, observational study conducted in three waves between October 2021 and August 2023. PRACTICE INNOVATION: Pharmacists conducted comprehensive vaccination need assessments. EVALUATION METHODS: The primary outcomes were numbers of vaccination needs per participant and vaccinations administered, scheduled, or declined. RESULTS: Pharmacists identified a mean of 1.8-2.2 unmet vaccination needs per adult assessed, more than in pilot studies. Participants had already received 61%-74% of vaccinations recommended for them hence 26%-39% of needs were unmet at baseline. The leading vaccination needs were COVID-19, influenza, zoster, tetanus-containing, and pneumococcal vaccines. From a baseline mean of 59.1% for these five vaccinations, pharmacists increased the mean percentage vaccinated to 73.2%. When an option for scheduling future vaccination was added to the process, declinations dropped from 46%-18%. CONCLUSION: This study provides insight into adult vaccine acceptance, willingness, and declination behaviors not described elsewhere. Offering options for future vaccination reduced declination rates. Pharmacists resolved substantial proportions of adult vaccination needs. The signal that apportioning adult vaccines needed, but not received on day of assessment, across several months could help resolve unmet vaccination needs warrants additional research, especially with the rising number of vaccines recommended for adults.
