Summary
Silicone-adjustable gastric banding (SAGB) offers a reversible bariatric surgery option. However, this 3-year study found a high rate of complications and re-operations, including band erosion and esophagitis.
Area of Science:
- Bariatric surgery
- Minimally invasive surgery
- Gastroenterology
Background:
- Silicone-adjustable gastric banding (SAGB) is a popular, reversible surgical treatment for morbid obesity.
- This study reports on a 3-year experience with SAGB, focusing on complications and side effects.
Purpose of the Study:
- To evaluate the outcomes of Silicone-adjustable gastric banding (SAGB) over a 3-year period.
- To identify and analyze the complications and side effects associated with SAGB.
Main Methods:
- A cohort of 90 patients (72 women, median age 42, median BMI 43 kg/m2) underwent SAGB using the Swedish band.
- Laparoscopic placement was attempted in 63 cases (75% success), with 16 conversions to laparotomy.
- Follow-up included clinical visits, upper GI series at 6 months, and gastroscopy at 2 years.
Main Results:
- Median BMI decreased to 31-32 kg/m2 by 24 months.
- 35% of patients required re-operation, most commonly for band erosion (10 patients) and erosive esophagitis (14 patients).
- At 2 years, over 50% reported vomiting, heartburn, or regurgitation, and 56% had esophagitis, though 78% remained satisfied.
Conclusions:
- SAGB can be placed laparoscopically in 75% of cases.
- The incidence of postoperative complications and side effects following SAGB is high.
- Re-operation is common, often due to band erosion or esophagitis.
