Resumo
Percutaneous endoscopic gastrostomy (PEG) currently represents the main alternative to ensure nutritional supply in patients with prolonged or permanent inability to swallow, and yet has a functional gastrointestinal tract. PEG performed with the Pull Technique is widely used because it is easy to perform and very safe, although it is associated with high infection rates. The Introducer Technique appears to be associated with a lower infection risk, although it requires fixation of the gastric wall to the abdominal wall (gastropexy), which makes the procedure difficult to perform. This study sought to describe and validate PEG performed with the Introducer Technique with the use of a new technical gastropexy variant, besides demonstrating its benefits in relation to risk of peristomal infection. A descriptive study of the safety and feasibility of a new technical gastropexy variant with a long curved needle was performed. We then compared the two gastropexy techniques in a before-and-after design. A randomized clinical trial comparing gastrostomy tubes constructed of different materials (latex vs. silicone) was also conducted. Finally, we performed a meta-analysis
evaluating peristomal infection risk between the Introducer Technique and Pull Technique. The results of these four studies are presented in four separate papers. The first study
showed that the new technical gastropexy variant that uses a long curved needle is safe and feasible. The second study showed that it is associated with a lower risk of infection compared with the gastropexy technique used previously. The third study found that the silicone tubes have greater durability than latex tubes. The final meta-analysis showed that PEG performed with the Pull Technique is associated with a greater risk of infection than the Introducer Technique.
