Treatment of uncomplicated meconium ileus via T-tube ileostomy
Insights
T-tube ileostomy with pancreatic enzyme irrigation is an effective treatment for neonates with meconium ileus unresponsive to nonoperative measures. This approach avoids resection of dilated bowel and facilitates rapid meconium expulsion.
Area of Science:
- Pediatric Surgery
- Neonatal Care
- Gastroenterology
Background:
- Meconium ileus is a common cause of intestinal obstruction in neonates.
- Nonoperative measures are the primary treatment, but surgical intervention is sometimes necessary.
- Traditional surgical approaches may involve resection of dilated bowel.
Purpose of the Study:
- To evaluate the efficacy of T-tube ileostomy with pancreatic enzyme irrigation for uncomplicated meconium ileus in neonates.
- To determine if resection of dilated ileum is necessary in these cases.
- To assess the safety and outcomes of this surgical technique.
Main Methods:
- A series of 11 infants with uncomplicated meconium ileus underwent T-tube ileostomy.
- Postoperative irrigation of the intestine utilized pancreatic enzyme.
- Infants were monitored for meconium passage and complications.
Main Results:
- 9 out of 11 infants successfully passed meconium between postoperative days 1 and 11.
- T-tubes were removed between postoperative days 10 and 14, with spontaneous tract closure.
- Resection of dilated ileum was not required in any of the successful cases.
- One infant required reexploration for persistent obstruction, and one infant died from unrelated complications.
Conclusions:
- T-tube ileostomy combined with pancreatic enzyme irrigation is a viable and effective treatment for meconium ileus.
- This method simplifies the procedure by avoiding mechanical meconium removal and bowel resection.
- The technique promotes rapid liquefaction and expulsion of meconium, leading to prompt intestinal function.
Abstract:
There are many treatment modalities for uncomplicated meconium ileus. However, for neonates with intestinal obstruction unrelieved by nonoperative measures we advocate T-tube ileostomy with postoperative irrigation of the intestine utilizing pancreatic enzyme. Our series includes 11 infants with uncomplicated meconium ileus who underwent T-tube ileostomy 24--96 hr after birth. Of the 7 females and 4 males only 2 infants failed to pass meconium. One infant required reexploration for persistent obstruction and 1 infant, the only death encountered, had overwhelming pulmonary infection and intracranial hemorrhage. The remaining 9 infants passed meconium between the 1st and 11th postop days. The T-tube was removed by pulling it out between the 10th and the 14th postop day with the T-tube tract closing spontaneously in all patients. Our experience with T-tube ileostomy suggests that resection of dilated but viable ileum is not necessary for prompt intestinal function in the neonate. With the use of pancreatic enzyme irrigation, the tenacious meconium in these patients can be rapidly liquified and expelled per rectum or T-tube and the necessity of mechanical removal during the operative procedure avoided.
