RESUMEN
Objectives: To compare complications associated with percutaneous gastrostomies performed using PUSH and PULL techniques, whether endoscopic (PEG) or radiological (PRG), in a tertiary-level hospital. Methods: This was a prospective observational study. Adult patients who underwent percutaneous PULL or PUSH gastrostomy using PEG or PRG techniques at the Virgen del Rocio University Hospital and subsequently followed up in the Nutrition Unit between 2009-2020 were included. X2 tests or Fisher's test were used for the comparison of proportions when necessary. Univariate analysis was conducted to study risk factors for PRG-associated complications. Results: n = 423 (PULL = 181; PUSH = 242). The PULL technique was associated with a higher percentage of total complications (37.6% vs. 23.8%; p = 0.005), exudate (18.2% vs. 11.2%; p = 0.039), and irritation (3.3% vs. 0%; p = 0.006). In the total sample, there were 5 (1.1%) cases of peritonitis, 3 (0.7%) gastrocolic fistulas, and 1 (0.2%) death due to complications associated with gastrostomy. Gender, age, and different indications were not risk factors for a higher number of complications. The most common indications were neurological diseases (35.9%), head and neck cancer (29%), and amyotrophic lateral sclerosis (17.2%). Conclusions: The PULL technique was associated with more total complications than the PUSH technique, but both were shown to be safe techniques, as the majority of complications were minor.
RESUMEN
OBJECTIVES: We aimed to describe and compare the complications associated with different percutaneous radiologic gastrostomy (PRG) techniques. METHODS: A retrospective and prospective observational study was conducted. Patients who underwent a PRG between 1995-2020 were included. TECHNIQUES: A pigtail catheter was used until 2003, a balloon catheter without pexy was used between 2003-2009 and a balloon catheter with gastropexy was used between 2015-2021. For the comparison of proportions, X2 tests or Fisher's test were used when necessary. Univariate analysis was performed to study the risk factors for PRG-associated complications. RESULTS: n = 330 (pigtail = 114, balloon-type without pexy = 28, balloon-type with pexy = 188). The most frequent indication was head and neck cancer. The number of patients with complications was 44 (38.5%), 11 (39.2%) and 54 (28,7%), respectively. There were seven (25%) cases of peritonitis in the balloon-type without-pexy group and 1 (0.5%) in the balloon-type with-pexy group, the latter being the only patient who died in the total number of patients (0.3%). Two (1%) patients of the balloon-type with-pexy group presented with gastrocolic fistula. The rest of the complications were minor. CONCLUSIONS: The most frequent complications associated with the administration of enteral nutrition through PRG were minor and the implementation of the balloon-type technique with pexy has led to a decrease in them.
