Eficacia de la insuflación con dióxido de carbono en enteroscopia de un solo balón para determinar profundidad de intubación y dolor posprocedimiento en pacientes referidos para evaluación del intestino delgado

Abstract

Introduction

The intubation depth of the small bowel is limited by distention due to air insufflation during the procedure. Carbon dioxide (CO₂) is rapidly absorbed from the bowel lumen and prevents distention of abdomen.

Objective

A comparison was made between the effects of CO₂ and air insufflations on the intubation depth during single balloon enteroscopy (SBE), as well as post-procedure pain.

Design

Descriptive case series study and comparison of the results in a tertiary care hospital.

Patients and methods

A total of 147 SBE procedures were performed on 130 patients with suspected small bowel disease using CO₂ insufflation in 65 procedures, and air insufflation in 82. Enteroscopy was performed using an Olympus SIF 180-Q and a UCR CO₂ pump. Intubation depth was recorded using a validated form, and pos-procedure pain immediately after SBE and 12 hours later were evaluated.

Results

A total of 147 SBE procedures were performed on 130 patients with a mean small bowel intubation depth in the CO₂ group significantly larger than the air group (p=.008). An oral approach was used in 95 procedures, and anal in 52 procedureswith a mean intubation depth significantly larger in the CO₂ group (p=.035 and p=.004, respectively). Patient pain was significantly reduced in the CO₂ group.

Limitations

Descriptive study of two case series.

Conclusion

CO₂ insufflation significantly improves intubation depth in SBE and reduces abdominal pain.
