AIM: To evaluate the safety and efficacy of CO(2) insufflation compared with air insufflation in the endoscopic submucosal excavation (ESE) of gastrointestinal stromal tumors.
METHODS: Sixty patients were randomized to undergo endoscopic submucosal excavation, with the CO(2) group (n = 30) and the air group (n = 30) undergoing CO(2) insufflation and air insufflation in the ESE, respectively. The end-tidal CO(2) level (pETCO(2)) was observed at 4 time points: at the beginning of ESE, at total removal of the tumors, at completed wound management, and 10 min after ESE. Additionally, the patients' experience of pain at 1, 3, 6 and 24 h after the examination was registered using a visual analog scale (VAS).
RESULTS: Both the CO(2) group and air group were similar in mean age, sex, body mass index (all P > 0.05). There were no significant differences in PetCO(2) values before and after the procedure (P > 0.05). However, the pain scores after the ESE at different time points in the CO(2) group decreased significantly compared with the air group (1 h: 21.2 ± 3.4 vs 61.5 ± 1.7; 3 h: 8.5 ± 0.7 vs 42.9 ± 1.3; 6 h: 4.4 ± 1.6 vs 27.6 ± 1.2; 24 h: 2.3 ± 0.4 vs 21.4 ± 0.7, P < 0.05). Meanwhile, the percentage of VAS scores of 0 in the CO(2) group after 1, 3, 6 and 24 h was significantly higher than that in the air group (60.7 ± 1.4 vs 18.9 ± 1.5, 81.5 ± 2.3 vs 20.6 ± 1.2, 89.2 ± 0.7 vs 36.8 ± 0.9, 91.3 ± 0.8 vs 63.8 ± 1.3, respectively, P < 0.05). Moreover, the condition of the CO(2) group was better than that of the air group with respect to anal exsufflation.
CONCLUSION: Insufflation of CO(2) in the ESE of gastrointestinal stromal tumors will not cause CO(2) retention and it may significantly reduce the level of pain, thus it is safe and effective.
