Surgical Outcomes, Health Care Utilization, and Costs Associated with Staple Line Buttressing Among Primary Sleeve Gastrectomy Patients.

ABSTRACT: Purpose: Staple line buttressing is a method of reinforcing surgical staple lines using buttress materials. This study evaluated surgical outcomes, hospital utilization, and hospital costs associated with staple line buttressing among patients who underwent primary laparoscopic sleeve gastrectomy (PLSG) in the United States.

Methods: This was a retrospective cohort study using Premier Healthcare Database data from January 1, 2012 to December 31, 2017. Patients aged ??18 years who underwent PLSG were selected and assigned to buttress or non-buttress cohorts based on the use of buttress material during their hospitalization for PLSG (index). Propensity score matching (PSM) was conducted to balance patient demographic and clinical characteristics between the cohorts. Generalized estimating equation models were used to compare the clinical and economic outcomes of the matched buttress and non-buttress users during the index hospitalization.

Results: A total of 38,231 buttress and 27,349 non-buttress patients were included in the study. After PSM, 24,049 patients were retained in each cohort. Compared with non-buttress cohort, the buttress cohort patients had a similar rate of in-hospital leaks (0.28% vs 0.39%; p?=?0.160) and a lower rate of bleeding (1.37% vs 1.80%, p?=?0.015), transfusion (0.56% vs 0.77%, p?=?0.050), and composite bleeding/transfusion (1.57% vs 2.04%, p?=?0.019). Total costs ($12,201 vs $10,986, p?
Conclusions: Staple line buttressing was associated with an improvement in complication rates for bleeding and transfusion. Total and supply costs were higher in the buttress cohort, necessitating further research into cost-effective buttressing materials.

Project description:ImportanceIn any surgical procedure, various aspects of technique may affect patient outcomes. As new procedures enter practice, it is difficult to evaluate the association of each aspect of technique with patient outcomes.ObjectiveTo examine the associations between technique and outcomes in laparoscopic sleeve gastrectomy.Design, setting, and participantsIn this cohort study of bariatric surgery programs participating in a statewide surgical quality improvement collaborative, 30 surgeons submitted intraoperative videos from representative sleeve gastrectomies performed on 6915 patients with morbid obesity. These videos were reviewed by blinded peer surgeons on key technical elements, and 605 reviews were linked to sleeve gastrectomy outcomes of all of the surgeons' patients from January 1, 2015, to December 31, 2016.ExposuresSurgeons' technical approaches to 5 controversial aspects of laparoscopic sleeve gastrectomy: dissection of the proximal stomach, sleeve caliber, sleeve anatomy, staple line reinforcement, and leak testing.Main outcomes and measuresThe 30-day outcomes were rate of postoperative hemorrhage and staple line leak. The 1-year outcomes were percentage of total weight lost and reflux severity (Gastroesophageal Reflux Disease Health-Related Quality of Life instrument).ResultsA total of 30 surgeons submitted 46 videos of operations performed on 6915 patients (mean [SD] age, 45.4 [11.7] years; 5494 [79.5%] female; 4706 [68.1%] White). Complete dissection of the proximal stomach was associated with reduced hemorrhage rates (higher ratings for complete mobilization of fundus were associated with a decrease in hemorrhage rate from 2.1% [25th percentile] to 1.0% [75th percentile], P = .01; higher ratings for visualization of the left crus were associated with a decrease in hemorrhage rate from 1.5% to 0.94%, P = .006; and higher ratings for complete division of the short gastrics were associated with a decrease in hemorrhage rate from 2.8% to 1.2%, P = .03). The reduction in hemorrhage rates came at the expense of higher leak rates (higher ratings for complete mobilization of fundus were associated with an increase in leak rate from 0.05% [25th percentile] to 0.16% [75th percentile], P < .001; higher ratings for visualization of the left crus were associated with an increase in leak rate from 0.1% to 0.2%, P = .003; and higher ratings for complete division of the short gastrics were associated with an increase in leak rate from 0.02% to 0.1%, P = .01). Surgeons who stapled more tightly to the bougie had smaller decreases in reflux than those who stapled less tightly (-2.0 to -1.3 on a 50-point scale, P = .002). Staple line reinforcement (buttressing and oversewing) was associated with a small (2 of 1000 cases) decrease in hemorrhage rates. Staple line buttressing was also associated with a similarly small increase in leak rates (1 of 1000 cases). Leak testing was associated with a statistically insignificant change in the staple line leak rate (0.16%-0.22%, P = .47).Conclusions and relevanceVariations in surgical technique can be measured by video review and are associated with differences in patient outcomes.

Project description:ImportanceStudies comparing contemporary bariatric surgical types could facilitate procedure selection for patients interested in reducing their frequency of health care visits and reliance on prescription drugs.ObjectiveTo compare the association of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) with ambulatory health care costs and use for as long as 4 years after surgery.Design, setting, and participantsThis comparative effectiveness study, which included patients undergoing bariatric surgery who were aged 18 to 64 years with at least 24 months of enrollment data before surgery and 12 months of enrollment data after surgery, used a retrospective interrupted time series with a comparison group. Data represent insurance claims dated January 2006 to June 2017, with analyses completed in September 2021. Data were collected from US commercial and Medicare Advantage claims database. Cohorts were matched on characteristics including baseline body mass index category, diabetes status, baseline ambulatory care costs, region of the United States, and year of surgery.ExposuresSG or RYGB, based on procedure codes.Main outcomes and measuresAnnual ambulatory health care costs, and subtypes of cost and use including prescriptions, office visits, laboratory encounters, and radiology.ResultsMatched cohorts included 3049 patients who underwent SG and 3251 patients who underwent RYGB, with a mean (SD) age of 45.2 (10.0) years; 4820 (77%) were women. Full follow-up was 37% for SG (514 patients) and 38% for RYGB (643 patients) among those eligible for 4-year follow-up. There were no significant differences between SG and RYGB in total ambulatory costs, office visit costs, or radiology costs in all follow-up years. Patients who underwent SG had significantly higher prescription costs than those who underwent RYGB bypass in year 4 ($852.8 per patient per year; 95% CI: $395.6-$1310.0 per patient per year) with more cardiometabolic medication fills in each year (eg, year 4: 42.5%; 95% CI, 13.7%-71.2%). In contrast, early after surgery, patients who underwent SG had relatively fewer specialist visits (eg, year 1: -7.2%; 95% CI, -14.3% to -0.2%) and lower laboratory costs (eg, year 1: -$118.9 per patient per year; 95% CI, -$220.2 to -$17.5 per patient per year).Conclusions and relevanceDespite clinical studies showing greater weight loss and comorbidity improvement with RYGB vs SG, this study found no difference in total ambulatory costs for as long as 4 years after SG and RYGB. These findings may reflect the trade-off between greater improvements in cardiometabolic health and additional surgery-related care among patients undergoing RYGB. Studies with longer follow-up time could determine whether greater sustained weight loss from RYGB eventually results in lower costs compared with SG.
