RESUMO
This prospective, randomized controlled trial was undertaken to evaluate the effect of tube decompression of the stomach after surgical procedure on the digestive tract. One hundred and nine patients were randomly allocated to postoperative treatment with (57 patients) or without (52 patients) nasogastric tubes. No significant differences were found between the two groups in the duration of hospitalization, time to begin peroral fluid intake, occurrence of hiccups, vomiting, nausea, parotiditis, nasal septum necrosis, anastomotic leak and wound dehiscence. Moreover, abdominal distension, pyrosis, otalgia, dysphagia, odynophagia and atelectasis occurred more often in intubated patients as shown by chi-square analysis of the data with Yates correction, with the level of significance at p = less than 0.05. Tube decompression of the stomach does not relieve intestinal paralysis after digestive operations. These data seem to indicate that the routine prophylactic use of a nasogastric tube is unnecessary in gastrointestinal operations.
