Surgical and endoscopic treatment: indications, class of evidence and recommendations
| Surgical treatment of oesophageal perforations | Recommended | Class of evidence* |
|---|---|---|
| IA | ||
| Perforation <24 h | IC | |
| Primary repair | Perforation <72 h | |
| Thoracic small perforation (failure off medical treatment) | NA** | |
| Abdominal perforations <24 h | IA | |
| Drainage only | Cervical perforations | IIC |
| Thoracic small perforations | NA | |
| Diversion without esophagectomy | Severe mediastinitis after large thoracic perforations in critical patient | IIC |
| Advance stages of oesophageal cancer perforations | IIC | |
| Severe mediastinitis after large thoracic perforations if general conditions | IIC | |
| Esophagectomy | allow | |
| Initially stages of oesophageal cancer | IA | |
| Endoscopic closure system vacuum-(E-VAC) assisted | Large perforations with an efficient peri-oesophageal drainage | IIC |
| Oesophageal stenting associated with pleural/mediastinal drainage | Thoracic perforations<24 h in stable patients Bridging method for critical patients | IIC |
[i] *Class of evidence and recommendations:
[ii] Levels:
[iii] I - High-quality prospective cohort study with adequate power or systematic review of these studies
[iv] II - Lesser quality prospective cohort, retrospective cohort study, untreated controls from a randomised control trials (RCT) point of view, or systematic review of these studies Grade Practice Recommendations
[v] A - Strong recommendation; B- Recommendation; C - Option
