Readmission Following Laparoscopic Sleeve Gastrectomy

Area of Science:

• Bariatric Surgery
• Gastroenterology
• Surgical Outcomes

Background:

• Laparoscopic sleeve gastrectomy (LSG) has established readmission rates between 1.7-4.33%.
• These rates are comparable to other bariatric procedures.
• This study focuses on 30-day readmission after primary LSG at a Center of Excellence.

Purpose of the Study:

• To determine the incidence of 30-day readmission following primary LSG.
• To identify potential risk factors associated with readmission after LSG.
• To evaluate the impact of clinical pathway changes on readmission rates.

Main Methods:

• Analysis of 343 consecutive LSG procedures performed by a single surgeon.
• Comparison of readmitted patients with non-readmitted patients using statistical tests (Student's t-test, chi-squared test).
• Review of patient demographics, comorbidities, and perioperative factors.

Main Results:

• A 3.5% (12/343) 30-day readmission rate was observed, with no mortalities or major complications.
• No specific risk factors for readmission were identified.
• Readmission rates were significantly lower in the later cohort (2% vs 7%) after clinical pathway modifications, including elimination of routine esophagograms and adoption of a 1-day stay.

Conclusions:

• 30-day readmission rates for LSG are consistent with other bariatric procedures.
• Clinical pathway optimization may reduce readmission rates.
• Further prospective research is needed to elucidate LSG-specific complication and readmission patterns.
