Surgery for EPS was contraindication in 1990’s

Most patients treated surgically died due to technical

complications. These deaths occurred by anastomosis failure

because the pathogenesis of EPS was not well understood by

surgeons, and, in many cases, simple resection of adherent

intestinal loops with enteroanastomosis was performed.

However, the final option for patients in whom bowel

obstruction symptoms fail to improve is surgical enterolysis,

Clinical Practice GL PD in Adults and Children, The National Institute for Health and Care Excellence (NICE), June 2017

Guideline 7.2.1 – PD : Encapsulating Peritoneal Sclerosis: Management

• We recommend that patients with EPS should be referred or discussed

early with units who have expertise in EPS surgery. Surgery should be

performed by teams experienced in EPS surgery (GRADE 1B).

ISPD-GL

• It must be stated, though, that for surgical results to be successful, the

surgical team must have a thorough understanding of the pathology of

EPS. Such surgery should therefore only be done in specialist regional

centers that can provide appropriate surgical training and patient support.

Indication of surgery for EPS

Severe bowel obstruction: risk of bowel perforation

Malnutrition

Conclusion

EPS surgical experience and outcomes during 24 years in a

single center were reported; patients who undergo the

surgery showed better outcomes.

The increase in surgical treatment rate in the world promoted

improvements in countermeasures against and better

understanding of EPS.

Currently, EPS is no longer recognized as a fatal

complication.
