RESUMO
BACKGROUND: Clinical care pathways help guide and provide structure to clinicians and providers to improve healthcare delivery and quality. The Quality Improvement and Patient Safety Committee (QIPS) of the American Society for Metabolic and Bariatric Surgery (ASMBS) has previously published care pathways for the performance of laparoscopic sleeve gastrectomy (LSG) and pre-operative care of patients undergoing Roux-en-Y gastric bypass (RYGB). OBJECTIVE: This current RYGB care pathway was created to address intraoperative care, defined as care occurring on the day of surgery from the preoperative holding area, through the operating room, and into the postanesthesia care unit (PACU). METHODS: PubMed queries were performed from January 2001 to December 2019 and reviewed according to Level of Evidence regarding specific key questions developed by the committee. RESULTS: Evidence-based recommendations are made for care of patients undergoing RYGB including the pre-operative holding area, intra-operative management and performance of RYGB, and concurrent procedures. CONCLUSIONS: This document may provide guidance based on recent evidence to bariatric surgeons and providers for the intra-operative care for minimally invasive RYGB.
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.
RESUMO
OBJECTIVE: Obesity and associated comorbidities, such as NAFLD, impose a major healthcare burden worldwide. Bariatric surgery remains the most successful approach for sustained weight loss and the resolution of obesity-related complications. However, the impact of preexisting NAFLD on weight loss after bariatric surgery has not been previously studied. The goal of this study is to assess the impact of preexisting NAFLD on weight loss outcomes up to 5 years after weight loss surgery. RESEARCH DESIGN AND METHODS: Data from the Michigan Bariatric Surgery Cohort (MI-BASiC) was extracted to examine the effect of baseline NAFLD on weight loss outcomes. The cohort included a total of 714 patients older than 18 years of age undergoing gastric bypass (GB; 380 patients) or sleeve gastrectomy (SG; 334 patients) at the University of Michigan between January 2008 and November 2013. Repeated measure analysis was used to determine if preexisting NAFLD was a predictor of weight loss outcomes up to 5 years post-surgery. RESULTS: We identified 221 patients with an established clinical diagnosis of NAFLD at baseline. Multivariable repeated measure analysis with adjustment for covariates shows that patients with preexisting NAFLD had a significantly lower percentage of total and excess weight loss compared to patients without preexisting NAFLD. Furthermore, our data show that baseline dyslipidemia is an indicator of the persistence of NAFLD after bariatric surgery. CONCLUSIONS: Our data show that patients' body weight loss in response to bariatric surgery is impacted by factors such as preexisting NAFLD. Additionally, we show that NAFLD may persist or recur in a subset of patients after surgery, and thus careful continued follow-up is recommended.

BACKGROUND: Although patients with lower socioeconomic status are at higher risk of obesity, bariatric surgery utilization among patients with Medicaid is low and may be due to program-specific variation in access. Our goal was to compare bariatric surgery programs by percentage of Medicaid cases and to determine if variation in distribution of patients with Medicaid could be linked to adverse outcomes. METHODS: Using a state-wide bariatric-specific data registry that included 43 programs performing 97,207 cases between 2006 and 2020, we identified all patients with Medicaid insurance (n = 4780, 4.9%). Bariatric surgery programs were stratified into quartiles according to the percentage of Medicaid cases performed and we compared program-specific characteristics as well as baseline patient characteristics, risk-adjusted complication rates and wait times between top and bottom quartiles. RESULTS: Program-specific distribution of Medicaid cases varied between 0.69 and 22.4%. Programs in the top quartile (n = 11) performed 18,885 cases in total, with a mean of 13% for Medicaid patients, while programs in the bottom quartile (n = 11) performed 32,447 cases in total, with a mean of 1%. Patients undergoing surgery at programs in the top quartile were more likely to be Black (20.2% vs 13.5%, p < 0.0001), have diabetes (35.1% vs 29.5%, p < 0.0001), hypertension (55.1% vs 49.6%, p < 0.0001) and hyperlipidemia (47.6% vs 45.2%, p < 0.0001). Top quartile programs also had higher complication rates (8.4% vs 6.6%, p < 0.0001), extended length of stay (5.6% vs 4.0%, p < 0.0001), Emergency Department visits (8.1% vs 6.5%, p < 0.0001) and readmissions (4.7% vs 3.9%, p < 0.0001). Median time from initial evaluation to surgery date was also significantly longer among top quartile programs (200 vs 122 days, p < 0.0001). CONCLUSIONS: Bariatric surgery programs that perform a higher proportion of Medicaid cases tend to care for patients with greater disease severity who experience delays in care and also require more resource utilization. Improving bariatric surgery utilization among patients with lower socioeconomic status may benefit from insurance standardization and program-centered incentives to improve access and equitable distribution of care.

INTRODUCTION: Technical variation exists when performing the gastrojejunostomy during Roux-en-Y gastric bypass (RYGB). However, it is unclear whether changing technique results in improved outcomes or patient harm. METHODS: Surgeons participating in a state-wide bariatric surgery quality collaborative who completed a survey on how they perform a typical RYGB in 2011 and again in 2021 were included in the analysis (n = 31). Risk-adjusted 30-day complication rates and case characteristics for cases in 2011 were compared to those in 2021 among surgeons who changed their gastrojejunostomy technique from end-to-end anastomosis (EEA) to either a linear staple or handsewn anastomosis (LSA/HSA). In addition, case characteristics and outcomes among surgeons who maintained an EEA technique throughout the study period were assessed. RESULTS: A total of 15 surgeons (48.3%) changed their technique from EEA to LSA/HSA while 7 surgeons (22.3%) did not. Nine surgeons did LSA or HSA the entire period and therefore were not included. Surgeons who changed their technique had significantly lower rates of surgical complications in 2021 when compared to 2011 (1.9% vs 5.1%, p = 0.0015), including lower rates of wound complications (0.5% vs 2.1%, p = 0.0030) and stricture (0.1% vs 0.5%, p = 0.0533). Likewise, surgeons who did not change their EEA technique, also experienced a decrease in surgical complications (1.8% vs 5.8%, p < 0.0001), wound complications (0.7% vs 2.1%, p < 0.0001) and strictures (0.2% vs 1.2%, p = 0.0006). Surgeons who changed their technique had a significantly higher mean annual robotic bariatric volume in 2021 (30.0 cases vs 4.9 cases, p < 0.0001) when compared to those who did not. CONCLUSIONS: Surgeons who changed their gastrojejunostomy technique from circular stapled to handsewn demonstrated greater utilization of the robotic platform than those who did not and experienced a similar decrease in adverse events during the study period, despite altering their technique. Surgeons who chose to modify their operative technique may be more likely to adopt newer technologies.

INTRODUCTION: Depression is strongly associated with obesity and is common among patients undergoing bariatric surgery. Little is known about the impact of depression on early postoperative outcomes or its association with substance use. METHODS: The Michigan Bariatric Surgery Collaborative is a statewide quality improvement program that maintains a large clinical registry. We evaluated patients undergoing primary Roux-en-Y gastric bypass or sleeve gastrectomy between 2017 and 2022. Patients self-reported symptoms of depression (PHQ-8) and use of alcohol (AUDIT-C), smoking, prescription opiates, and marijuana at baseline. Preoperative PHQ-8 scores stratified patients based on severity: no depression (0-4), mild (5-9), moderate (10-14), or severe (15-24). We compared 30-day outcomes and substance use between patients with and without depression. RESULTS: Among 44,301 patients, 30.8% had some level of depression, with 19.8% mild, 7.5% moderate, and 3.5% severe. Patients with depression were more likely to have an extended length of stay (LOS) (> 3 days) than those without depression (no depression 2.1% vs. severe depression 3.0%, p = 0.0452). There were no significant differences between no depression and severe depression groups in rates of complications (5.7% vs. 5.2%, p = 0.1564), reoperations (0.9%, vs. 0.8%, p = 0.7394), ED visits (7.7% vs. 7.8%, p = 0.5353), or readmissions (3.2% vs. 3.9%, p = 0.3034). Patients with severe depression had significantly higher rates of smoking (9.7% vs. 12.5%, p < 0.0001), alcohol use disorder (8.6% vs. 14.0%, p < 0.0001), opiate use (14.5% vs. 22.4%, p < 0.0001) and marijuana use (8.4%, vs. 15.5%, p = 0.0008). CONCLUSIONS: This study demonstrated that nearly one-third of patients undergoing bariatric surgery have depression, with over 10% in the moderate to severe range. There was a significant association between preoperative depressive symptoms and extended LOS after bariatric surgery, as well as higher rates of smoking and use of marijuana, prescription opiates and alcohol. There was no significant effect on adverse events or other measures of healthcare utilization.

RESUMO
BACKGROUND: Despite increasing marijuana use nationwide, there are limited data on implications of marijuana use on bariatric surgery outcomes. OBJECTIVE: We investigated associations between marijuana use and bariatric surgery outcomes. SETTING: Multicenter statewide study utilizing data from the Michigan Bariatric Surgery Collaborative, a payor-funded consortium including over 40 hospitals and 80 surgeons performing bariatric surgery statewide. METHODS: We analyzed data from the Michigan Bariatric Surgery Collaborative clinical registry on patients who underwent a laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass between June 2019 and June 2020. Patients were surveyed at baseline and annually on medication use, depression symptoms, and substance use. Regression analysis was performed to compare 30-day and 1-year outcomes between marijuana users and nonusers. RESULTS: Of 6879 patients, 574 reported baseline marijuana use and 139 reported use at baseline and 1 year. Marijuana users were more likely to be current smokers (14% versus 8%, P < .0001), screen positive for alcohol use disorder (20.0% versus 8.4%, P < .0001), and score higher on the Patient Health Questionnaire-8 (6.1 versus 3.0, P < .0001). There were no statistically significant differences in 30-day outcomes or co-morbidity remission at 1 year. Marijuana users had higher adjusted total mean weight loss (47.6 versus 38.1 kg, P < .0001) and body mass index reduction (17 versus 14 kg/m2, P < .0001). CONCLUSIONS: Marijuana use is not associated with worse 30-day outcomes or 1-year weight loss outcomes and should not be a barrier to bariatric surgery. However, marijuana use is associated with higher rates of smoking, substance use, and depression. These patients may benefit from additional mental health and substance abuse counseling.

OBJECTIVE: For patients with obesity and diabetes, bariatric surgery can lead to the remission of both diseases. However, the possible impact of diabetes on the magnitude of weight loss outcomes after bariatric surgery has not been precisely quantified. RESEARCH DESIGN AND METHODS: Data from Michigan Bariatric Surgery Cohort (MI-BASiC) was extracted to examine the effect of baseline diabetes on weight loss outcomes. Consecutive patients older than 18 years of age undergoing gastric bypass (GB) or sleeve gastrectomy (SG) for obesity at University of Michigan between January 2008 and November 2013 were included. Repeated measures analysis was used to determine if diabetes was a predictor of weight loss outcomes over 5 years postsurgery. RESULTS: Out of the 714 included patients, 380 patients underwent GB [mean BMI 47.3 ± 0.4 kg/m2 , diabetes 149 (39.2%)] and 334 SG [mean BMI 49.9 ± 0.5 kg/m2 , diabetes 108 (32.3%)]. Multivariable repeated measures analysis showed, after adjusting for covariates, that individuals with diabetes had a significantly lower percentage of total (p = .0023) and excess weight loss (p = .0212) compared to individuals without diabetes. CONCLUSIONS: Our data demonstrate that patients with diabetes undergoing bariatric surgery would experience less weight loss than patients without diabetes.

BACKGROUND: Metabolic surgery is the most effective treatment for obesity and may improve obesity-related pain syndromes. However, the effect of surgery on the persistent use of opioids in patients with a history of prior opioid use remains unclear. OBJECTIVE: To determine the effect of metabolic surgery on opioid use behaviors in patients with prior opioid use. SETTING: A consortium of public and private hospitals in Michigan. METHODS: Using a statewide metabolic-specific data registry, we identified 16,820 patients who self-reported opioid use before undergoing metabolic surgery between 2006 and 2020 and analyzed the 8506 (50.6%) patients who responded to 1-year follow-up. We compared patient characteristics, risk-adjusted 30-day postoperative outcomes, and weight loss between patients who self-reported discontinuing opioid use 1 year after surgery and those who did not. RESULTS: Among patients who self-reported using opioids before metabolic surgery, 3864 (45.4%) discontinued use 1 year after surgery. Predictors of persistent opioid use included an annual income of <$10,000 (odds ratio [OR] = 1.24; 95% confidence interval [CI], 1.06-1.44; P = .006), Medicare insurance (OR = 1.48; 95% CI, 1.32-1.66; P < .0001), and preoperative tobacco use (OR = 1.36; 95% CI, 1.16-1.59; P = .0001). Patients with persistent use were more likely to have a surgical complication (9.6% versus 7.5%, P = .0328) and less percent excess weight loss (61.6% versus 64.4%, P < .0001) than patients who discontinued opioids after surgery. There were no differences in the morphine milligram equivalents prescribed within the first 30 days following surgery between groups (122.3 versus 126.5, P = .3181). CONCLUSIONS: Nearly half of patients who reported taking opioids before metabolic surgery discontinued use at 1 year. Targeted interventions aimed at high-risk patients may increase the number of patients who discontinue opioid use after metabolic surgery.

BACKGROUND: Concurrent hiatal hernia repair (HHR) during laparoscopic sleeve gastrectomy (LSG) may improve gastroesophageal reflux disease (GERD) symptoms. However, patient-reported outcomes are limited, and the influence of surgeon technique remains unclear. OBJECTIVES: To assess patient-reported GERD severity before and after LSG with and without concomitant HHR. SETTING: Teaching and non-teaching hospitals participating in a state-wide quality improvement collaborative. METHODS: Using a state-wide bariatric-specific data registry, all patients who underwent a primary LSG between 2015 and 2019 who completed a baseline and 1 year validated GERD health related quality of life (GERD-HRQL) survey were identified (n = 11,742). GERD severity at 1 year as well as 30-day risk-adjusted adverse events was compared between patients who underwent LSG with or without HHR. Results were also stratified by anterior versus posterior HHR. RESULTS: A total of 4015 patients underwent a LSG-HHR (34%). Compared to patients who underwent LSG without HHR, LSG-HHR patients were older (47.8 yr versus 44.6 yr; P < .0001), had a lower preoperative body mass index (BMI) (45.8 kg/m2 versus 48 kg/m2; P < .0001) and more likely to be female (85.2% versus 77.6%, P < .0001). Patients who underwent a posterior HHR (n = 3205) experienced higher rates of symptom improvement (69.5% versus 64.0%, P = .0014) and lower rates of new onset symptoms at 1 year (28.2% versus 30.2%, P = .0500). Patients who underwent an anterior HHR (n = 496) experienced higher rates of hemorrhage and readmissions with no significant difference in symptom improvement. CONCLUSIONS: Concurrent posterior hiatal HHR at the time of sleeve gastrectomy can improve reflux symptoms. Patients undergoing anterior repair derive no benefit and should be avoided.

BACKGROUND: Although bariatric surgery is the most effective treatment for obesity and weight-related comorbid diseases, utilization rates are disproportionately low among non-white patients. We sought to understand if variation in baseline characteristics or access to care exists between white and non-white patients. METHODS: Using a statewide bariatric-specific data registry, we evaluated all patients who underwent bariatric surgery between 2006 and 2020 and completed a preoperative baseline questionnaire, which included a question about self-identification of race. Patient characteristics, co-morbidities, and time from initial preoperative clinic evaluation to date of surgery were compared among racial groups. RESULTS: A total of 73,141 patients met inclusion criteria with 18,741 (25.5%) self-identified as non-white. These included Black/African American (n = 11,904), Hispanic (n = 3448), Asian (n = 121), Native Hawaiian/Pacific Islander (n = 41), Middle Eastern (n = 164), Multiple (n = 2047) and other (n = 608). Non-white males were the least represented group, accounting for only 4% of all bariatric cases performed. Non-white patients were more likely to be younger (43.0 years vs. 46.6 years, p < 0.0001), disabled (16% vs. 11.4%, p < 0.0001) and have Medicaid (8.4% vs. 3.8%, p < 0.0001) when compared to white patients, despite having higher rates of college education (78.0% vs. 76.6, p < 0.0001). In addition, median time from initial evaluation to surgery was also longer among non-white patients (157 days vs. 127 days, p < 0.0001), despite having higher rates of patients with a body mass index above 50 kg/m2 (39.0% vs. 33.2%, p < 0.0001). CONCLUSIONS: Non-white patients undergoing bariatric surgery represent an extremely diverse group of patients with more socioeconomic disadvantages and longer wait times when compared to white patients despite presenting with higher rates of severe obesity. Current guidelines and referral patterns for bariatric surgery may not be equitable and need further examination when considering the management of obesity within diverse populations to reduce disparities in care-of which non-white males are particularly at risk.

CONTEXT: Weight loss after bariatric surgery can be accurately predicted using an outcomes calculator; however, outliers exist that do not meet the 1 year post-surgery weight projections. OBJECTIVE: Our goal was to determine how soon after surgery these outliers can be identified. DESIGN: We conducted a retrospective cohort study. SETTING, PATIENTS, AND INTERVENTION: Using a bariatric surgery outcomes calculator formulated by the Michigan Bariatric Surgery Collaborative (MBSC), predicted weight loss at 1 year post-surgery was calculated on all patients who underwent primary bariatric surgery at a single-center academic institution between 2006 and 2015 who also had a documented 1-year follow-up weight (n = 1050). MAIN OUTCOME MEASURES: Weight loss curves were compared between high, low, and non-outliers as defined by their observed-to-expected (O:E) weight loss ratio based on total body weight loss (TBWL) %. RESULTS: Mean predicted weight loss for the study group was 39.1 ± 9.9 kg, while mean actual weight loss was 39.7 ± 17.1 kg resulting in a mean O:E 1.01 (± 0.35). Based on analysis of the O:E ratios at 1 year post-surgery, the study group was sub-classified. Low outliers (n = 188, O:E 0.51) had significantly lower weight loss at 2 months (13.1% vs 15.6% and 16.5% TBWL, p < 0. 001) and at 6 months (19% vs 26% and 30% TBWL, p < 0.001) when compared to non-outliers (n = 638, O:E 1.00) and high outliers (n = 224, O:E 1.46), respectively. CONCLUSIONS: Weight loss curves based on individually calculated outcomes can help identify low outliers for additional interventions as early as 2 months after bariatric surgery.

BACKGROUND: Portomesenteric vein thrombosis (PVT) is a rare complication following bariatric surgery but can result in severe morbidity as well as death. OBJECTIVE: Identification of risk factors for PVT to facilitate targeted management strategies to reduce incidence. SETTING: Prospective, statewide bariatric-specific clinical registry. METHODS: We identified all patients who underwent primary bariatric surgery between June 2006 and November 2021 (n = 102,869). Patient characteristics, procedure type, operative details, and 30-day postoperative complications were analyzed with multivariable logistic regression to evaluate for independent predictors of PVT. RESULTS: A total of 117 patients (.11%) developed a postoperative PVT, with 6 (5.1%) associated deaths. The majority of PVTs occurred in patients who underwent sleeve gastrectomy (109 patients; 93.2%), and the PVT occurred most commonly during the second (37%), third (31%), and fourth weeks (23%) after surgery. Independent risk factors for PVT included a prior history of venous thromboembolism (odds ratio [OR] = 3.1; 95% confidence interval [CI]: 1.64-5.98; P = .0005), liver disorder (OR = 2.3; 95% CI: 1.36-4.00; P = .0021), undergoing sleeve gastrectomy (OR = 12.4; 95% CI: 4.98-30.69; P < .0001), and postoperative complications including obstruction (OR = 12.5; 95% CI: 4.65-33.77; P < .0001), leak (OR = 7.9; 95% CI: 2.76-22.64; P = .0001), and hemorrhage (OR = 7.6; 95% CI: 3.57-16.06; P < .0001). CONCLUSIONS: Independent predictors of PVT include a prior history of venous thromboembolism, liver disease, undergoing sleeve gastrectomy, and experiencing a serious postoperative complication. Given that the incidence of PVT is most common within the first month after surgery, extending postdischarge chemoprophylaxis during this time frame is advised for patients with increased risk.

INTRODUCTION: Repairing a hiatal hernia at the time of laparoscopic sleeve gastrectomy (SG) can reduce or even prevent gastroesophageal reflux disease (GERD) symptoms in the post-operative period. Several different hiatal hernia repair techniques have been described but their impact on GERD symptoms after SG is unclear. METHODS: Surgeons (n = 74) participating in a statewide quality collaborative were surveyed on their typical technique for repair of hiatal hernias during SG. Options included posterior repair with mesh (PRM), posterior repair (PR), and anterior repair (AR). Patients who underwent SG with concurrent hiatal hernia repair (n = 7883) were compared according to their surgeon's reported technique. Patient characteristics, baseline and 1-year GERD health-related quality of life surveys, weight loss and 30-day risk-adjusted complications were analyzed. RESULTS: The most common technique reported by surgeons for hiatal hernia repair was PR (n = 64, 85.3%), followed by PRM (n = 7, 9.3%) and AR (n = 4, 5.3%). Patients who underwent SG by surgeons who perform AR had lower rates of baseline GERD diagnosis (AR 55.3%, PR 59.5%, PRM 64.8%, p < 0.01), but were more likely to experience worsening GERD symptoms at 1 year (AR 29.8%, PR 28.7%, PRM 28.2%, p < 0.0001), despite similar weight loss (AR 29.8%, PR 28.7%, PRM 28.2%, p = 0.08). Satisfaction with GERD symptoms at 1 year was high (AR 73.2%, PR 76.3%, PRM 75.7%, p = 0.43), and risk-adjusted 30-day outcomes were similar among all groups. CONCLUSIONS: Patients undergoing SG with concurrent hiatal hernia repair by surgeons who typically perform an AR were more likely to report worsening GERD at 1 year despite excellent weight loss. Surgeons who typically performed an AR had nearly one-half of their patients report increased GERD severity after surgery despite similar weight loss. While GERD symptom control may be multifactorial, technical approach to hiatal hernia repair at the time of SG may play a role and a posterior repair is recommended.
