The Laparoscopy in Biliary Exploration Research and Training Initiative (LIBERTI) trial: simulator-based training for laparoscopic management of choledocholithiasis.

BACKGROUND: Laparoscopic cholecystectomy with common bile duct exploration (LCBDE) is equivalent in safety and efficacy to endoscopic retrograde cholangiopancreatography (ERCP) plus laparoscopic cholecystectomy (LC) while decreasing number of procedures and length of stay (LOS). Despite these advantages LCBDE is infrequently utilized. We hypothesized that formal, simulation-based training in LCBDE would result in increased utilization and improve patient outcomes across participating institutions. METHODS: Data was obtained from an on-going multi-center study in which simulator-based transcystic LCBDE training curricula were instituted for attending surgeons and residents. A 2-year retrospective review of LCBDE utilization prior to LCBDE training was compared to utilization up to 2 years after initiation of training. Patient outcomes were analyzed between LCBDE strategy and ERCP strategy groups using χ2, t tests, and Wilcoxon rank tests. RESULTS: A total of 50 attendings and 70 residents trained in LCBDE since November 2020. Initial LCBDE utilization rate ranged from 0.74 to 4.5%, and increased among all institutions after training, ranging from 9.3 to 41.4% of cases. There were 393 choledocholithiasis patients analyzed using LCBDE (N = 129) and ERCP (N = 264) strategies. The LCBDE group had shorter median LOS (3 days vs. 4 days, p < 0.0001). No significant differences in readmission rates between LCBDE and ERCP groups (4.7% vs. 7.2%, p = 0.33), or in post-procedure pancreatitis (0.8% v 0.8%, p > 0.98). In comparison to LCBDE, the ERCP group had higher rates of bile duct injury (0% v 3.8%, p = 0.034) and fluid collections requiring intervention (0.8% v 6.8%, p < 0.009) secondary to cholecystectomy complications. Laparoscopic antegrade balloon sphincteroplasty had the highest technical success rate (87%), followed by choledochoscopic techniques (64%). CONCLUSION: Simulator-based training in LCBDE results in higher utilization rates, shorter LOS, and comparable safety to ERCP plus cholecystectomy. Therefore, implementation of LCBDE training is strongly recommended to optimize healthcare utilization and management of patients with choledocholithiasis.

Prevention of type 2 diabetes among youth: a systematic review, implications for the school nurse.

Childhood obesity and the early development of type 2 diabetes (T2 DM) place students at risk for chronic health problems. The school nurse is uniquely situated to promote school health initiatives that influence health behavior. The purpose of this review was to determine effective nonpharmacological interventions for prevention of T2 DM in youth. Researchers from 35 reports modified T2 DM risk factors. These nonpharmacological interventions often include increasing daily activity, decreasing caloric intake, and increasing muscle mass. Some researchers also included psychological and social support interventions intended to strengthen initiating and/or maintaining health behavior. Characteristics of effective nonpharmacological T2 DM prevention interventions are discussed. Findings from this review are a useful guide for the implementation of T2 DM prevention strategies in the school setting. Few school-based studies included high school students; therefore, further research is needed among older adolescents on the efficacy of nonpharmacological interventions in the high school.

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.

How many sleeve gastrectomies are done at nonaccredited centers in Texas?

BACKGROUND: The American College of Surgeons created the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) to improve the safety of surgery and track outcomes of patients undergoing metabolic and bariatric surgery. The MBSAQIP captures all surgical procedures performed at accredited centers (AC) but not all metabolic and bariatric surgery cases performed in the United States. Texas has a large statewide administrative database that tracks nearly all surgical procedures performed in the state and we proposed using this database to assess the number of sleeve gastrectomies (SG) and whether they were performed at an AC or not. OBJECTIVE: Our objective was to determine the percentage of SG that are performed in MBSAQIP ACs. SETTING: University surgical department, United States. METHODS: The Texas Inpatient and Outpatient Public Use Data Files (PUDF) for the year 2017 were examined. We used the Current Procedural Terminology and International Classification of Diseases version 10 codes for SG, 43775 and 0 DB64 Z3, respectively. We compared the PUDF facility list to a list of MBSAQIP ACs in Texas. RESULTS: There were 4549 SG performed in Texas in 2017 reported in the Outpatient PUDF. Of these, 80.8% of cases were performed at ACs. Of the 136 facilities in the outpatient PUDF performing SG, 58 were MBSAQIP accredited. In the Inpatient PUDF for 2017 there were 11,287 SG, of which 9829 (87%) were performed at ACs. Of 153 centers performing SG, 77 were MBSAQIP accredited. There was a higher percentage of adjustable band conversions to SG at non-ACs in the Outpatient PUDF than the Inpatient PUDF. CONCLUSION: The MBSAQIP database is missing almost 20% of outpatient SG performed in Texas and 13% of inpatient SG. Administrative databases can be used to externally validate the MBSAQIP.

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.

Trends in revisional bariatric surgery using the MBSAQIP database 2015-2017.

BACKGROUND: The third most common bariatric surgery is revisional bariatric surgery. The American College of Surgeons tracks outcomes using the Metabolic and Bariatric Surgery Accreditation Quality Initiative Program database. We used this database to examine trends in revisional bariatric surgery. OBJECTIVE: To evaluate how trends in bariatric revisional surgery have changed in recent years. SETTING: University Hospital, United States. METHODS: The Metabolic and Bariatric Surgery Accreditation Quality Initiative Program database for 2015 to 2017 was examined for revisions of bariatric surgery. Patients who underwent revisional bariatric surgery were identified by the primary Current Procedural Terminology code, the REVCONV and PREVIOUS_SURGERY field as well as secondary Current Procedural Terminology codes. There is no exact code for sleeve gastrectomy (SG) to laparoscopic Roux-en-Y gastric bypass (LRYGB), so we used 43644 (GB)+REVCONV+PREVIOUS_SURGERY for this. RESULTS: For the years 2015 to 2017 there were 57,683 revisions/conversions of 528,081 patients. The number of revisions increased over the study period by 5213 cases. The most common revision was laparoscopic adjustable gastric band (LAGB) to SG with 15,433 cases and the second was LAGB to LRYGB with 10,485 cases. There were 14,715 LAGB removals. It is more difficult to track SG to LRYGB but there were 8491 unlisted cases, which may have been sleeve to bypass. CONCLUSION: LAGBs are being taken out or converted, and this group makes up the largest portion of revisions and conversions. It is difficult to track SG to LRYGB, but the number of unlisted cases continues to climb. This will likely surpass LAGB conversions with time. The Metabolic and Bariatric Surgery Accreditation Quality Initiative Program should be modified to capture revisions/conversions of SG.

Are Concomitant Operations During Bariatric Surgery Safe? An Analysis of the MBSAQIP Database.

INTRODUCTION: The American College of Surgeons tracks 30-day outcomes using the Metabolic and Bariatric Surgery Accreditation Quality Initiative Program (MBSAQIP) database. We examined the short-term outcomes of patients that undergo bariatric surgery concomitantly with other operations such as hernia repairs and cholecystectomy to determine the safety of this practice. METHODS: The MBSAQIP Participant Use Data File for 2015-2017 was examined for differences in primary bariatric operations vs concomitant procedures (CP). We looked for concurrent CPT codes for laparoscopic cholecystectomy (LC) and hernia repairs (ventral, epigastric, incisional, and inguinal). p was significant at < 0.05. RESULTS: There were 464,674 cases, of which 15,614 had CP. For both LRYGB+LC and SG+LC, there were increased operative times and length of stay. There were statistically significant higher rates of readmission, reintervention, and reoperation for SG+LC vs SG alone, as well as for LRYGB+hernia and SG+hernia. There was a higher risk of death (p < 0.001) in LRYGB+hernia patients. Also, LRYGB+hernia patients had statistically significant increases in unplanned admission to the intensive care unit and pulmonary embolus. SG+hernia patients had a higher rate of ventilation > 48 h, unplanned admission to the ICU, pulmonary embolism, deep vein thrombosis, and readmission, reintervention, and reoperation. CONCLUSIONS: There is a statistically higher rate of complications with concomitant procedures in the MBSAQIP database. Length of stay and operative times are increased in concomitant operations as are readmissions, reinterventions, and reoperations. These findings would indicate that additional procedures at the time of bariatric surgery should be deferred if possible.

Factors Contributing to Morbidity after Combined Arterial and Venous Lower Extremity Trauma.

The purpose of this study was to evaluate the impact of management of venous injury on clinical outcomes in patients with combined lower extremity arterial and venous trauma. Patients with common and external iliac, common and superficial femoral, and popliteal artery injuries were identified. Patients who underwent vein repair and those who received vein ligation were compared. The analysis was repeated for those patients who required secondary intervention for their arterial injury and those who did not require secondary intervention. Seventy patients were identified with both arterial and venous injuries: 40 underwent vein ligation and 30 received vein repair. There was no difference in ischemic time between patients undergoing vein repair compared with ligation. Vein ligation did not produce a higher incidence of muscle debridement (10% vs 15%, P = 0.72), necessity for secondary intervention (10% vs 7.5%, P = 0.99), or amputation (3.3% vs 7.5%, P = 0.63). Patients who required secondary intervention had a greater degree of shock on presentation (packed red blood cells (PRBC), 13 units vs 6 units, P = 0.02) and were more likely to require muscle debridement (50% vs 9%, P = 0.02) and amputation (33% vs 3%, P = 0.03). Vein ligation did not impact muscle ischemia or success of arterial repair in patients with combined venous and arterial trauma in the lower extremities. Patient morbidity after extremity vascular trauma is most related to degree of shock.
