Trends and outcomes of minimally invasive surgery for gastrointestinal stromal tumors (GIST).

OBJECTIVE: Minimally invasive surgery (MIS) is increasingly being utilized for the resection of gastrointestinal cancers. National trends for perioperative and oncologic outcomes of MIS for gastrointestinal stromal tumors (GIST) are unknown. We hypothesized that with increased use of MIS, the perioperative outcomes and survival for GIST are preserved. METHODS: The National Cancer Database (2010-2016) was utilized to assess perioperative and oncologic outcomes for GIST of the stomach and small bowel. Kaplan-Meier method and log rank test were used to compare survival outcomes. RESULTS: Data from 8923 gastric and 3683 small bowel resections were analyzed. Over the study period, MIS became the prevalent modality for gastrectomies (2010: robotic: 2.4%, laparoscopic: 26.1%, open: 71.5% vs. 2016: robotic: 9.6%, laparoscopic: 48.8%, open: 41.6%; p < 0.001), with a smaller increase in enterectomies (2010: robotic: 1%, laparoscopic: 17.3%, open: 81.6% vs. 2016: robotic: 3.9%, laparoscopic: 27.2%, open: 68.9%; p < 0.001). Age and Charlson comorbidity index were similar among groups. MIS approaches were associated with fewer readmissions and lower 90 day mortality for gastrectomies and similar rates for enterectomies. MIS did not compromise patient survival even in patients who underwent neoadjuvant treatment or harbored tumors ≥ 10 cm. CONCLUSION: Minimally invasive surgery is increasingly being utilized for resection of gastric and small bowel GIST, with improved postoperative outcomes. In this retrospective review, overall survival after minimally invasive or open surgery was comparable, even in challenging scenarios of neoadjuvant treatment or large tumors (≥ 10 cm).

The impact of minimally invasive surgery and frailty on post-hepatectomy outcomes.

BACKGROUND: The impact of patient frailty on post-hepatectomy outcomes is not well studied. We hypothesized that patient frailty is a strong predictor of 30-day post-hepatectomy complications. METHODS: The liver-targeted National Surgical Quality Improvement Program (NSQIP) database for 2014-2019 was reviewed. A validated modified frailty index (mFI) was used. RESULTS: A total of 24,150 hepatectomies were reviewed. Worsening frailty was associated with increased incidence of Clavien-Dindo grade IV complications (mFI 0, 1, 2, 3, 4 was 3.9%, 6.3%, 10%, 8.1%, 50% respectively; p < 0.001). Minimally invasive hepatectomies had a lower rate of Clavien-Dindo grade IV complications for non-frail (Laparoscopic: 1%, Robotic: 2.6%, Open: 4.6%; p < 0.001) and frail patients (Laparoscopic: 3%, Robotic: 2.3%, Open: 7.7%; p < 0.001). Frail patients experienced higher incidence of post-hepatectomy liver failure (5.4% vs 4.1% for non-frail; p < 0.001) and grade C liver failure (28% vs 21.1% for non-frail; p = 0.03). Incorporating mFI to Albumin-Bilirubin score (ALBI) improved its ability to predict Clavien-Dindo grade IV complications (AUC improved from 0.609 to 0.647; p < 0.001) and 30-day mortality (AUC improved from 0.663 to 0.72; p < 0.001). CONCLUSION: Worsening frailty correlates with increased incidence of Clavien-Dindo grade IV complications post-hepatectomy, whereas minimally invasive approaches decrease this risk. Incorporating frailty assessment to ALBI improves its ability to predict major postoperative complications and 30-day mortality.

Trends in bariatric surgery in Texas: an analysis of a statewide administrative database 2013-2017.

BACKGROUND: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) tracks 30-day outcomes of bariatric patients, but only at accredited centers. Presently, these cases are not broken down by state. Administrative databases can be used to answer some of the questions that are not asked by clinical databases and also to validate those databases. We proposed using the inpatient and outpatient administrative databases in Texas to examine both the numbers and trends of bariatric surgery in Texas over a 5-year period. METHODS: The Texas Inpatient Public Use Data File (IPUDF) and the Texas Outpatient Public Data File (OPUDF) were examined for the years 2013-2017. We searched for patients undergoing laparoscopic adjustable gastric banding (LAGB), sleeve gastrectomy (SG), laparoscopic Roux-en-Y gastric bypass (LRYGB) and duodenal switch. Robotic assisted cases were also examined. RESULTS: There were 105,199 bariatric cases performed in Texas from 2013 to 2017. There were 173 centers performing bariatric surgery. The most common operation performed was the sleeve gastrectomy at 73,663 case (70% of total). Gastric bypasses were second at 22,890 cases. During this time period, LAGB almost disappeared; dropping from 2090 cases in 2013 to 115 cases in 2017, with removal of 2097 LAGB in the study period in the OPUDF. During this time period, there was a lower growth rate of the number of SG in the IPUDF with a large increase in SG performed with outpatient status, while LRYGB remained relatively stable. CONCLUSION: Rates of bariatric surgery in Texas are increasing slowly. The dominant procedure is the SG with a trend towards being done under outpatient status. LAGB has been essentially phased out. There is an increase in SG being performed under 'outpatient' status.

Small bowel obstructions following the use of barbed suture: a review of the literature and analysis of the MAUDE database.

BACKGROUND: Barbed suture has been adopted across all surgical specialties. One of the infrequent complications seen with the use of barbed suture is small bowel obstructions (SBOs). In this study, we perform a review of the literature and the Manufacturer and User Facility Device Experience Database (MAUDE) to characterize SBOs after the use of barbed sutures in a variety of operative procedures. METHODS: A review of the literature was performed by searching PubMed and Ovid. We used the search terms: "barbed," "suture," "bowel," and "obstructions." For each case report, we examined the initial surgical procedure, type of barbed suture used, the type of complication, the time to complication, the presentation, and the type of operative interventions required. We did the same with the MAUDE database. RESULTS: Our review of the literature revealed 18 different cases of SBO secondary to the use of barbed suture. The four most common procedures, with a total of four cases each, were inguinal hernia procedures, myomectomy, hysterectomy, and pelvic floor reconstructive procedures. The average time of presentation to SBO was found to be 26.3 days post-op (1-196 days). A total of 16 patients (88.9%) presented with abdominal pain. Other common complaints included vomiting (33.3%), abdominal distension (27.8%), oral intolerance (22.2%), and constipation (16.7%). A total of 5 cases were also found to have a possible volvulus on computed tomography (CT), and 2 cases were reported to have strangulation. The MAUDE database had 14 cases reporting on obstruction. CONCLUSIONS: Surgeons should have a high index of suspicion for SBO if a patient presents with obstructive symptoms after a surgery that used barbed suture. This will often present as a mesenteric volvulus on CT. These particular SBOs require operative exploration, with laparoscopy being successful in the majority of cases.

Evaluation of the rate of marginal ulcer formation after bariatric surgery using the MBSAQIP database.

BACKGROUND: Marginal ulcer (MU) formation is a known problem after gastric bypass. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database contains data from all US and Canadian Centers of Excellence including complication rates. We hypothesized that the short-term rate of ulceration is low. METHODS: We queried the MBSAQIP database for the year 2015. We searched patients with primary gastric bypass who developed MU. We then compared preoperative, operative, and postoperative characteristics with patients who did not develop MU. RESULTS: The incidence of MU in the entire cohort of GB patients was 155 of 44,379 (0.35%, 95% CI 0.297%, 0.409%). Among the 155 patients with an ulcer, 88 (57%) patients had only one procedure, 69 had an intervention (therapeutic or diagnostic endoscopy), 16 had readmission, and 3 had reoperation. 65 patients (42%) had two procedures with the majority having both readmissions and endoscopy (n = 59); and two patients (1%) had three procedures. Ulcer formation was most common in the intervention group (11.4%). The occurrence of ulcer formation was associated with unplanned ICU admissions (6.45%), transfusions (5.16%), postoperative UTI (3.87%), sepsis (1.94%), and myocardial infarction (0.65%). Death occurred in 76 patients with no related cases to MUs. The risk of ulcer was associated with increased BMI (OR 1.02, p = 0.01), presence of percutaneous transluminal cardiac catheterization (PTC) (2.17, p = 0.038), histories of DVT (1.72, p = 0.085), and pulmonary embolism (2.84, p = 0.002). CONCLUSIONS: In a nationally reported database, symptomatic MUs rarely occur in the first month. The large majority are diagnosed and treated endoscopically with minimal need for surgical intervention. The risk of anastomotic ulcer was increased with increased BMI, need for PTC, and history of DVT/PE.

Ethnic disparities in traumatic brain injury care referral in a Hispanic-majority population.

BACKGROUND: Functional outcomes after traumatic brain injury (TBI) can be significantly improved by discharge to posthospitalization care facilities. Many variables influence the discharge disposition of the TBI patient, including insurance status, patient condition, and patient prognosis. The literature has demonstrated an ethnic disparity in posthospitalization care referral, with Hispanics being discharged to rehabilitation and nursing facilities less often than non-Hispanics. However, this relationship has not been studied in a Hispanic-majority population, and thus, this study seeks to determine if differences in neurorehabilitation referrals exist among ethnic groups in a predominately Hispanic region. METHODS: This study is a retrospective cohort that includes 1128 TBI patients who presented to University Medical Center El Paso, Texas, between the years 2005 and 2015. The patients' age, sex, race, residence, admission Glasgow Coma Scale (GCS), GCS motor, Injury Severity Score (ISS), hospital and intensive care unit length of stay (LOS), mechanism of injury, and discharge disposition were analyzed in univariate and multivariate models. RESULTS: Our study population had an insurance rate of 55.5%. Insurance status and markers of injury severity (hospital LOS, intensive care unit LOS, ISS, GCS, and GCS motor) were predictive of discharge disposition to rehabilitation facilities. The study population was 70% Hispanic, yet Hispanics were discharged to rehabilitation facilities (relative risk: 0.56, P: 0.001) and to long-term acute care/nursing facilities (relative risk: 0.35, P < 0.0001) less than non-Hispanics even after LOS, ISS, ethnicity, insurance status, and residence were adjusted for in multivariate analysis. CONCLUSIONS: This study suggests that patients of different ethnicities but comparable traumatic severity and insurance status receive different discharge dispositions post-TBI even in regions in which Hispanics are the demographic majority.

Cultural adaptation of a brief motivational intervention for heavy drinking among Hispanics in a medical setting.

BACKGROUND: Hispanics, particularly men of Mexican origin, are more likely to engage in heavy drinking and experience alcohol-related problems, but less likely to obtain treatment for alcohol problems than non-Hispanic men. Our previous research indicates that heavy-drinking Hispanics who received a brief motivational intervention (BMI) were significantly more likely than Hispanics receiving standard care to reduce subsequent alcohol use. Among Hispanics who drink heavily the BMI effectively reduced alcohol use but did not impact alcohol-related problems or treatment utilization. We hypothesized that an adapted BMI that integrates cultural values and addresses acculturative stress among Hispanics would be more effective. METHODS/DESIGN: We describe here the protocol for the design and implementation of a randomized (approximately 300 patients per condition) controlled trial evaluating the comparative effectiveness of a culturally adapted (CA) BMI in contrast to a non-adapted BMI (NA-BMI) in a community hospital setting among men of Mexican origin. Study participants will include men who were hospitalized due to an alcohol related injury or screened positive for heavy drinking. By accounting for risk and protective factors of heavy drinking among Hispanics, we hypothesize that CA-BMI will significantly decrease alcohol use and alcohol problems, and increase help-seeking and treatment utilization. DISCUSSION: This is likely the first study to directly address alcohol related health disparities among non-treatment seeking men of Mexican origin by comparing the benefits of a CA-BMI to a NA-BMI. This study stands to not only inform interventions used in medical settings to reduce alcohol-related health disparities, but may also help reduce the public health burden of heavy alcohol use in the United States. TRIAL REGISTRATION: Trial registration clinicaltrials.gov identifier NCT02429401; Registration date: April 28, 2015.

Understanding the burden of traumatic injuries at the United States-Mexico border: A scoping review of the literature.

ABSTRACT: The US-Mexico border is the busiest land crossing in the world and faces continuously increasing numbers of undocumented border crossers. Significant barriers to crossing are present in many regions of the border, including walls, bridges, rivers, canals, and the desert, each with unique features that can cause traumatic injury. The number of patients injured attempting to cross the border is also increasing, but significant knowledge gaps regarding these injuries and their impacts remain. The purpose of this scoping literature review is to describe the current state of trauma related to the US-Mexico border to draw attention to the problem, identify knowledge gaps in the existing literature, and introduce the creation of a consortium made up of representatives from border trauma centers in the Southwestern United States, the Border Region Doing Research on Trauma Consortium. Consortium members will collaborate to produce multicenter up-to-date data on the medical impact of the US-Mexico border, helping to elucidate the true magnitude of the problem and shed light on the impact cross-border trauma has on migrants, their families, and the US health care system. Only once the problem is fully described can meaningful solutions be provided.

Injuries sustained after falls from bridges across the United States-Mexico border at El Paso.

OBJECTIVE: To compare demographics and motivations for falls from bridges at the United States-Mexico border and in El Paso County, Texas, and to analyze injuries and injury patterns to support intentionality and to provide treatment recommendations. METHODS: A retrospective observational review was conducted of hospital admissions to a trauma center after falls from bridges from 1995 to 2009. Statistical methods used were chi-square testing, T-test for means comparison, univariate correlations, and regression analysis. RESULTS: Of the 97 evaluated patients, 81.4% fell from U.S.-Mexico border bridges, including one patient who fell from a railway bridge; 74.7% of those falling from border bridges had a non-U.S. address, contrasting with 22.2% of those who fell within the United States. Falls over the border were associated with more immigration-related motivations and fewer suicide attempts. Injuries included lower extremities in 76 (78.4%) and thoracolumbar spine in 27 (27.8%) patients; 16 patients with a thoracolumbar spine fracture (59.3%) also had a lower extremity injury. Mean hospital length of stay was 7.2 days. Mean injury severity score was 8.45 (range 1-43). Age, injury severity score, and pelvic fracture increased the hospital length of stay. CONCLUSIONS: Patients fell while emigrating-immigrating based on residence and motivating factors. A dyad of lower extremity and thoracolumbar spine injuries coincided in 59.3% of those with a thoracolumbar spine injury; thoracolumbar spine imaging of patients evaluated after falls from bridges is recommended. Proposed prevention strategies include posting signs on bridges and installing catch-net safety barriers.

Blunt Thoracic Aortic Injury and Contemporary Management Strategy.

Thoracic aortic injury (TAI) is a leading cause of death in blunt chest trauma. Motor vehicle collisions are the commonest cause, and most patients die before receiving medical attention. Survivors who make it to the hospital also typically have other debilitating injuries with high morbidity. It is imperative to understand the nature of these injuries and implement current management strategies to improve patient outcomes. A literature review on contemporary management strategies on blunt thoracic aortic injuries was performed to evaluate the available evidence using online databases (PubMed and Google Scholar). We found that there has been an improved survival owing to the current advancement in diagnostic modalities, the use of contrast-enhanced computed tomography angiography, and contemporary management techniques with an endovascular approach. However, careful assessment of patients and a multidisciplinary effort are necessary to establish an accurate diagnosis. Minimal aortic injuries (intimal tear and aortic hematoma) can be managed medically with careful monitoring of disease progression with imaging. Endovascular approaches and delayed intervention are key strategies for optimal management of high-grade TAI.

Evaluating the change in patterns of traumatic injury in the setting of pandemic and social distancing restrictions: An analysis of a level 1 trauma center.

BACKGROUND: Social distancing measures and quarantine during the COVID-19 pandemic have led to reported changes in traumatic injury patterns. We set to examine the effects of these restrictive guidelines in our trauma center. METHODS: This is a retrospective chart review of all patients evaluated for traumatic injuries at a Level 1 trauma center during two time periods: March-June 2020 (COVID) and March-June 2019 (Pre-COVID). RESULTS: Overall trauma volume did not differ significantly between the two time periods. Changes seen during COVID included increases in penetrating injuries (12.5% vs 6.7%, p < 0.001), particularly those due to firearms (7.5% vs 3.7%, p < 0.001). Hospital length of stay, intensive care unit length of stay, and days on the ventilator remained consistent between the two groups. Trends toward increased injuries in the home and non-accidental trauma were not statistically significant. CONCLUSION: Traumatic injury patterns have changed as a result of social distancing in both the adult and pediatric trauma populations. Analyzing the effects of social distancing on trauma can lead to a better development of preventive strategies.

Pancreatic Neuroendocrine Tumors: The Effect of Facility Type on Patient Survival.

OBJECTIVES: During the last decades, significant progress has been made in the management of patients with pancreatic neuroendocrine tumors (pNETs). It is unclear how the type of the treating health care facility alters patient outcomes. METHODS: Data from pNETs reported to the National Cancer Database between 2004 and 2016 were examined. Types of institutions were as follows: academic/research cancer program (ARP), comprehensive community cancer program (CCCP), integrated network cancer program (INCP), and community cancer program (CCP). RESULTS: A total of 17,887 patients with pNETs were analyzed. Treatment at ARPs was significantly associated with receipt of surgery (ARP, 61.9%; CCCP, 45.6%; CCP, 29.9%; INCP, 55.5%; P < 0.001), both for patients with very early tumors ≤2 cm (ARP, 74.7%; CCCP, 66.5%; CCP, 52.4%; INCP, 71.6%; P < 0.001) and for patients with liver metastases (ARP, 21.3%; CCCP, 10.6%; CCP, 5%; INCP, 16.8%; P < 0.001). Treatment at ARPs was associated with improved survival (median overall survival: ARP, 91 mo; CCCP, 47 mo; CCP, 24.5 mo; INCP, 72 mo; P < 0.001). CONCLUSIONS: Treatment of pNETs at academic/research programs is associated with more frequent resections and best survival outcomes. This survival benefit exists for early and late stages and after adjusting for known cofactors.

Relative adrenal insufficiency in the critical care setting: debunking the classic myth.

BACKGROUND: Classic teaching states that chronic adrenal insufficiency is associated with hyponatremia, hyperkalemia, hypercalcemia, hypoglycemia, and eosinophilia. We hypothesize that these diagnostic markers do not predict relative adrenal insufficiency (RAI) in the critically ill or injured patient. METHODS: Chart review of surgical, trauma, and medical patients admitted over 7 years to a critical care unit was performed to evaluate cortisol levels drawn for suspicion of RAI, which was defined as a cortisol concentration <25 mcg/dl. Laboratory parameters were defined as hyponatremia <135 mmol/l, hyperkalemia >5.3 mmol/l, hypercalcemia >2.55 mmol/l (10.2 mg/dl), hypoglycemia <3.89 mmol/l (70 mg/dl), and eosinophilia >5%. RESULTS: A total of 212 patients had cortisol levels drawn. Fifty-seven percent were male and their mean age was 59 years. Fifty-three percent had RAI. Average cortisol level was 30.5 µg/dl. No significant differences were seen in mean potassium, sodium, calcium, or glucose levels between RAI and non-RAI patients. Few patients had laboratory values consistent with RAI. In fact, many with RAI had opposite findings: 75% had hypernatremia, 90% had hypokalemia, 100% had hypocalcemia, and 97% had hyperglycemia. Eosinophilia was statistically significant (P = 0.026). CONCLUSION: Hyponatremia, hyperkalemia, hypercalcemia, and hypoglycemia do not predominate in RAI and laboratory values are of minimal value in predicting patients with RAI.

Electronic trauma patient outcomes assessment tool: performance improvement in the trauma intensive care unit.

An electronic dashboard can enhance compliance with a specific checklist of indicators with daily management of injured patients in a trauma intensive care unit effectively. A performance management electronic dashboard monitored 24 indicators in the trauma intensive care unit over a 3-year period. Over a 3-year period, utilization of the electronic dashboard improved from 64% to 100% and mean compliance rose from 94.8% to 97.4%. Implementation of an electronic dashboard enhances compliance in managing trauma patients in a sustainable manner, allows immediate correction of deficiencies, monitors trends, and facilitates performance improvement/patient safety initiatives of a trauma program.

Facility Type Affects Treatment Outcomes for Patients With Mucinous Cystic Neoplasms and Intraductal Papillary Mucinous Neoplasms of the Pancreas.

OBJECTIVE: Academic centers report better outcomes for pancreatic ductal adenocarcinoma. We hypothesized that treatment outcomes for mucinous cysts differ according to institution type. METHODS: Using the National Cancer Data Base, we analyzed data on patients with mucinous cystic neoplasms (MCNs) and intraductal papillary mucinous neoplasms (IPMNs). RESULTS: Of 3278 identified patients, 2622 (80%) had IPMNs and 656 (20%) had MCNs. While most academic/research programs (ARCPs, 84.9%) treated more than 10 patients/year, this was true for only 59% of integrated network cancer programs, 37.3% of comprehensive community cancer programs, and 0% of community cancer programs (P < 0.001). Surgery was used more often in ARCPs and for smaller tumors. The ARCPs had higher rates of margin negative resections with retrieval of 15 or more nodes with the lowest 30- and 90-day mortality rates. The median overall survival was better in ARCPs (110.3 months) than comprehensive community cancer programs (75.1 mo), community cancer programs (75.1 mo), or integrated network cancer programs (100.8 mo, P < 0.001). CONCLUSIONS: Treatment of MCNs and IPMNs of the pancreas at academic centers is associated with a higher probability of pancreatectomy, disease identification in a noninvasive stage, and better overall survival. Centralization of care for mucinous pancreatic cysts will lead to improved outcomes.

Laparoscopic aspiration cytology in rheumatoid ascites: a case report.

BACKGROUND: To the best of our knowledge, there are currently no recorded cytologic features of any effusion from rheumatoid peritonitis showing cytologic findings linked to rheumatoid pleural disease, although rheumatoid nodules have been described in the peritoneum. CASE: A 75-year-old man with longstanding, poorly controlled rheumatoid arthritis was seen in our hospital after a motor vehicle collision. Computed tomography showed free fluid in the abdominal cavity. Laparoscopic examination revealed a large amount of nonhemorrhagic ascitic fluid and no traumatic intraabdominal injuries. Abdominal and peritoneal surfaces appeared completely normal. The ascitic fluid was aspirated through the laparoscope and sent for cytologic examination. Cytospin preparations revealed histiocytes and loosely cohesive clusters of small cytologically bland epithelioid cells amid acute inflammatory cells and granular necrotic debris. Cell block material displayed transected fibroconnective tissue fragments lined by hyperplastic mesothelium with squamous metaplasia. Immunohistochemical studies revealed that the mesothelial cells were positive for calretinin, cytokeratin 5/6, and p63. CONCLUSION: The ascites was attributed to peritoneal disease from rheumatoid arthritis, based on the cytologic findings, immuno-profile, exclusion of other possible causes (i.e., cirrhosis, nephrotic syndrome, protein-losing enteropathy, or drugs), and patient's clinical setting.

The MBSAQIP is going viral! 194 hits and still going strong.

BACKGROUND: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) first released its Participant Use Data File in 2015. Since then, surgeons have eagerly evaluated data now available on >750,000 patients, and a yearly increase in the number of publications using the Participant Use File was anticipated. OBJECTIVE: To evaluate the impact of the MBSAQIP in surgical literature. SETTING: University surgical department, United States. METHODS: A literature search was performed to identify articles published using the MBSAQIP database up to March 2019. PubMed, Clinical Key (both indexed for MEDLINE), and Cochrane databases were queried using the keywords "MBSAQIP" and "Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program." Abstracts presented at ObesityWeek, SAGES, and the Clinical Congress of the ACS in 2016 to 2019 were also examined. Duplicates, letters to the editor, commentaries, statements, and position pieces were excluded. Articles describing projects that used MBSAQIP data to study <5 accredited centers were also excluded. RESULTS: As of March 2019, there were 114 results in PubMed, 216 results in Clinical Key, and 0 in Cochrane using the search terms. Additionally, 184 abstracts were included from the journal supplements from ObesityWeek, SAGES, and the Clinical Congress of the ACS. After elimination of duplicates, there were 327 total results. After exclusions, 55 published manuscripts and 126 abstracts remained. CONCLUSION: The MBSAQIP is a resounding success. A substantial body of research has already been produced from it and is growing with time. Gaps in current knowledge are being targeted through analyses of this single, large-scale database. The MBSAQIP will remain a valuable leading resource in metabolic and bariatric surgery.

Concomitant Hiatal Hernia Repair with Sleeve Gastrectomy: A 5-Year Analysis.

Background: The sleeve gastrectomy (SG) can be associated with postoperative gastroesophageal reflux and when a hiatal hernia (HH) is present, it should be fixed. Earlier studies have shown that 20% of SG have a concomitant hiatal hernia repair (SG+HHR). The aim of this project is to determine the rate of SG+HHR in a large state administrative database. Methods: The Texas Inpatient Public Use Data File (IPUDF) and Outpatient Public Use Data File (OPUDF) for the years 2013-2017 were examined for patients that underwent SG+HHR at the same time. Patient demographics, diagnosis, and charge data were also examined. A t-test was performed between groups and P was considered significant at < 0.05. Results: In the OPUDF, there were 6,193 (33.7%) patients who underwent SG+HHR out of 18,403 patients who underwent SG. Mean charges were $94,741 [standard deviation (SD) = $87,284]. Length of stay (LOS) was 2.1 (SD = 3.5) vs 2.3 days (SD = 3.3) with a shorter stay for SG+HHR vs SG alone (P < 0.001). In the IPUDF, there were 11,536 (21.1%) patients who underwent SG+HHR out of 54,545 patients who underwent SG. Mean charges were $69,006 (SD = $46,365). LOS was 1.59 days (SD = 3.7) for SG+HHR vs 1.63 days (SD = 1.6) for SG (P = .043). The rate of SG+HHR increased over the study period. Conclusions: SG+HHR is common in both the outpatient and inpatient setting. There is a yearly trend of increasing rates of SG+HHR.

Disparities in Access to Bariatric Surgery in Texas 2013-2017.

BACKGROUND: Access to bariatric care varies across regions, ethnic, and racial groups. Some of these variations may be due to insurance status or socioeconomic status. There are also regional and state variations in access to metabolic and bariatric surgery (MBS). The Texas Inpatient Public Use Data File (IPUDF) and Texas Outpatient Public Use Data File is a state-mandated database that collects information on demographics, procedures, diagnoses, and cost on almost all admissions in Texas. We used them to examine racial disparities in MBS over a 5-y period. METHODS: The IPUDF and Texas Outpatient Public Use Data File were examined from the years 2013 through, 2017. We included all patients undergoing a laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy and examined the demographics of these patients. Race and ethnicity are reported separately. We used U.S. Census Bureau statistics and the Texas Department of State Health Services statistics to determine the crude (unadjusted) and adjusted procedure rates of patients undergoing MBS. RESULTS: In the IUPUDF, the crude unadjusted procedure rate for blacks undergoing MBS was 7.29 per 10,000 population followed by 6.85 per 10,000 for non-Hispanic whites. Hispanics had the lowest rate at 3.20 per 10,000. When adjusted for sex, obesity, age, and race, blacks still had a higher rate of access followed by whites and then Hispanics. CONCLUSIONS: There are disparities to access for bariatric surgery in Texas. Blacks have the greatest access followed by whites. Hispanics have the lowest procedure rate per population.

Conversions to open surgery greatly increase complications: an analysis of the MBSAQIP database.

BACKGROUND: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database tracks patients, techniques, and outcomes for 30 days. The overwhelming majority of cases reported are performed using a laparoscopic technique. Bariatric surgeons rarely have to convert from laparoscopy to open surgery. OBJECTIVES: We examined the MBSAQIP to determine the characteristics of patients who underwent conversion and evaluated their short-term outcomes. SETTINGS: University program in the United States and nationwide clinical database. METHODS: The MBSAQIP Public Use File for 2017 was examined for primary bariatric operations. We identified patients who underwent a sleeve gastrectomy or gastric bypass using a minimally invasive technique. We identified patients who underwent conversion to another operative technique or were converted to open surgery and analyzed preoperative characteristics and postoperative complication rates. Relative risks (RR) were calculated for complications. P value was significant at < .05. RESULTS: There were 186,962 patients in the entire cohort. Six hundred nine patients underwent conversion from the original surgical approach to either open surgery (n = 457) or to another technique (n = 152). Patients with preoperative oxygen dependency, poor functional status, previous foregut/obesity surgery, preoperative renal insufficiency, and anticoagulation were more likely to undergo conversion. Patients who underwent conversion to the open approach had longer operative times (191 versus 86.6 min [P < .001]) and longer time to discharge (6.2 versus 1.6 d [P < .001]). The RR of death was 18.2 (95% confidence interval 8.7-37.6, P < .001) for procedures converted to open. The RR of sepsis was 10.1 (95% confidence interval 4.2-24.2, P < .001) and the RR for all complications was increased throughout for patients undergoing conversion. CONCLUSIONS: Patients in the MBSAQIP database that undergo conversion to the open surgical approach are at a greatly increased risk for death and complications.
