Sleeve Gastrectomy: the first 3 Years: evaluation of emergency department visits, readmissions, and reoperations for 14,080 patients in New York State

Abstract

Introduction

The purpose of our study was to evaluate the indications for and incidence of both emergency department (ED) visits and hospital readmissions within the first postoperative year. We also sought to identify the rate of reoperation within the first 3 years following a SG operation in New York State (NYS).

Methods

The SPARCS database was examined for all SGs performed between 2011 and 2013. Using a unique identifier, patients were followed for at least 1 year. Patients were followed for reoperation and/or conversion to Roux-en-Y Gastric Bypass (RYGB), as well as for any other hospital-based encounter. Using primary diagnosis codes, the top five reasons for ED visits and readmission were identified.

Results

There were 14,080 SG between 2011 and 2013. Among all patients, just over one-third of patients visited the ED (33.9%). One in every ten of these visits resulted in readmission (9.5%), with 12.5% of the total postoperative patient population undergoing readmission within their first year after SG surgery. ED visits were unrelated to surgery in just over half of the patients (n = 4977; 53.88%). However, ED visits for abdominal pain (n = 1029; 11.14%), vomiting (n = 237; 2.57%), dehydration (n = 224; 2.43%), and syncope (n = 206; 2.23%) were attributed to surgery. The top five causes for readmission within the first year after SG were unrelated to surgery (n = 1101; 41.74%), complication related to bariatric surgery (n = 211; 8%), dehydration (n = 171; 6.48%), postoperative wound complication (n = 89; 3.37%), abdominal pain (n = 78; 2.96%). Overall, there was a low reoperation rate (0.32%); specifically, rates of sleeve revision and conversion to RYBG were 0.11 and 0.21%, respectively.

Conclusion

SG has increasing popularity in NYS. Although postoperative ED visits are high, SG has a low overall reoperation rate (0.32%), and of these patients, most undergo conversion to RYGB compared to sleeve revision. Overall 1-year readmission rates after SG are 12.5%.
