High acuity sleeve gastrectomy patients in a free-standing ambulatory surgical center.

BACKGROUND

Procedures performed in ambulatory surgical centers (ASC) can provide several advantages over hospital-based surgery. Understandably, concerns have been raised regarding "high acuity" cases in the ASC setting. Recently the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) presented protocols for ASCs to follow, requiring them to perform only "low acuity" cases to be compliant with accreditation.

OBJECTIVE

Assess the safety and efficacy of outpatient sleeve gastrectomy (SG) on the "high acuity patient" in a free-standing ASC.

SETTING

Free-standing ASC, Eviva Bariatrics, Seattle, Washington.

METHODS

Data were collected retrospectively for all patients who underwent sleeve gastrectomy from January 1, 2013 to December 31, 2015, n = 1112. Of those patients, 120 were classified as "high acuity."

RESULTS

Mean age was 51.7 years (24-73), mean body mass index was 42.4 (26.2-65.9). Mean operative time was 91 minutes. Five patients (4.2%) were readmitted within 30 days. Causes of re-admission were portal vein thrombosis (n = 2), intra-abdominal abscess (n = 1), infected hematoma (n = 1), and postoperative bleeding (n = 1). One patient (0.83%) was transferred from the ASC to a nearby hospital due to a postoperative bleed. One patient (0.83%) had a re-operation to evacuate a hematoma. One patient had a re-operation to wash out an infected hematoma. There were 0 confirmed staple line leaks. There were no open conversions and no deaths within 30 days or at 1 year. Follow-up was 83% (n = 100) at 6 months, and 65.0% at 1 year (n = 78).

CONCLUSION

Criteria such as age, body mass index, or prior bariatric surgery did not reflect worse outcomes in a specialized ASC. With experienced surgeons, appropriate protocols, and a consistent operative team, SG can be performed safely in a free-standing ASC on select "high acuity" patients.
