Pseudocysts of the pancreas may require drainage or resection during t
heir evolution. External drainage can be considered as a treatment of
first resort with low related morbidity. It also offers a means of tre
ating patients with major contraindications for surgery. In our experi
ence, however, only 55% of external drainages prove successful. Theref
ore, surgical treatment, even at the cost of low-rate morbidity, remai
ns the only final treatment for complications linked to pseudocysts of
the pancreas. In the long term, however, these results depend on the
etiology of the pseudocysts.
