Achalasia. Short-term clinical monitoring after pneumatic dilation
1Gastroenterology Unit, Yale University School of Medicine, New Haven, Connecticut 06510.
Abstract:
Although concern about perforation has led physicians to perform pneumatic dilation for achalasia with routine contrast radiography immediately afterwards and with hospitalization, the need for these precautions has not been demonstrated. In contrast, we have routinely performed pneumatic dilations without contrast studies or hospitalization, and we hereby present our experience. During a recent six-year period, 110 pneumatic dilations were performed, and 71 of the last 73 were performed as outpatients with about 5-8 hr of clinical monitoring. Detailed review of 100 records showed that only 15 patients underwent contrast studies because of pain or fever. Perforation occurred in seven of the 15 patients, all of whom underwent surgery successfully. Short-term follow-up in patients who did not sustain perforation showed good or excellent results in 82%. Thus, it has been our experience that pneumatic dilation could be safely performed in achalasia without routine use of contrast studies or hospitalization.
Insights
Pneumatic dilation for achalasia can be safely performed without routine contrast studies or hospitalization. This approach reduces patient burden while maintaining good outcomes, challenging traditional safety protocols.
Area of Science:
- Gastroenterology
- Esophageal Motility Disorders
Background:
- Pneumatic dilation is a common treatment for achalasia.
- Traditional protocols involve contrast radiography and hospitalization due to perforation concerns.
Purpose of the Study:
- To evaluate the safety and efficacy of pneumatic dilation for achalasia without routine contrast studies or hospitalization.
- To challenge the necessity of current stringent safety measures.
Main Methods:
- Retrospective review of 110 pneumatic dilations over six years.
- Analysis of 71 outpatient procedures with 5-8 hours of monitoring.
- Correlation of contrast study use with adverse events.
Main Results:
- 15 patients (15%) received contrast studies due to pain or fever.
- Seven perforations occurred, all successfully managed surgically.
- 82% of non-perforated patients achieved good or excellent short-term results.
Conclusions:
- Pneumatic dilation for achalasia can be safely performed on an outpatient basis without routine contrast studies.
- The findings suggest that current precautions may be excessive.
- This approach offers a less burdensome treatment option for achalasia patients.
