Randomised clinical trial investigating the effects of combined administration of octreotide and methylglucamine diatrizoate in the older persons with adhesive small bowel obstruction

Objective: To investigate the effects of combined administration of octreotide and methylglucamine diatrizoate in the older persons with adhesive small bowel obstruction. Patients and methods: One hundred and sixty-two consecutive patients who had suffered from adhesive intestinal obstruction without clinical evidence of strangulation or gangrene were randomised into two groups, a control group (treated conservatively, n = 82) and a contrast group (treated with combined administration of octreotide and methylglucamine diatrizoate, n = 80). A laparotomy was performed in both the two groups if symptoms of strangulation developed or the obstruction did not resolve spontaneously after 72 h. Results: Statistically significant rapid reduction in pain score, lower amount of nasogastric drainage, shorter hospital stay, lower operative rate and lower postoperative morbidity were observed in the contrast group. Among the non-operative patients, earlier passage of stool and gas, earlier first oral intake and shorter duration of nasogastric tube placement were significantly more frequently observed in the contrast group. No difference in the rate of readmission was found between the two groups. Conclusions: Combined administration of octreotide and methylglucamine diatrizoate accelerates resolution of small bowel obstruction by a specific therapeutic effect and is safe for the older persons.
