Nonoperative management of esophageal strictures following esophagomyotomy for achalasia

Endoscopic balloon dilatation of esophageal strictures in infants and children: 17 years' experience and a literature review

PURPOSE

Whereas endoscopic balloon dilatation (EBD) of benign esophageal strictures is an established mode of therapy in adults, this has not been accepted universally in the pediatric population. The aim of this study is to report the safety, efficacy, and long-term results of EBD for children in the authors' center.

METHODS

Between 1986 and 2002, a total of 77 children (median age, 1.8 years; range, 2 months to 20 years) were treated by EBD for various causes: 2 had achalasia, and 75 had esophageal strictures (postesophageal atresia repair, 63; reflux esophagitis, 7; postfundoplication, 2; caustic injury, 3). Dilatations were performed using flexible endoscopy and fluoroscopic screening under general anesthesia.

RESULTS

A total of 260 dilatations were carried out with the mean number of EBD per patient being 3.4 (range, 1 to 19). A mean period of 5 months (maximum, 28 months) for each patient was required. Four complications of esophageal perforations (1.5%) were observed, but only one required surgical repair because of persistent leakage. The remaining patients have undergone long-term follow-up (median follow-up, 6.6 years), and all are asymptomatic.

CONCLUSIONS

This large series has shown that EBD can provide a safe and effective mean of relieving esophageal strictures with good long-term results.

Surgical management of achalasia

Although achalasia is not a common illness in the United States and Europe, there continues to be a need for surgical therapy for treatment. Laparoscopic Heller myotomy and partial fundoplication has, for the most part, replaced open surgery (abdominal or thoracic) as the surgical treatment of choice. In order to perform this procedure well, one must select patients carefully, evaluate them fully, and adhere to the technical principles required to achieve consistently good results.

Role of nuclear medicine in evaluating patients with suspected gastrointestinal motility disorders

Functional symptoms caused by gastrointestinal motility disorders are relatively common in the general population. Knowledge of the relationship between symptoms and the underlying gastrointestinal dysmotility provides physicians with a framework for successful evaluation and treatment of patients with possible motor disorders of the gastrointestinal tract. Scintigraphy provides for noninvasive and quantitative assessment of physiological transit throughout the gastrointestinal tract, and it is extremely useful for diagnosing gastrointestinal motor dysfunction. The wide range of scintigraphic studies now available supplement other diagnostic tests for evaluation of all segments of the gastrointestinal tract.
