Chyloperitoneum is not rare and is often associated with other chylous disorders particularly in more complex clinical conditions. An accurate diagnostic study is indispensable to plan the correct therapeutic approach, and we examined the long-term outcomes of our experience in the management of primary and secondary chyloperitoneum in fifty-eight patients (50 adults and 8 children; 34 primary and 24 secondary forms). Diagnostic assessment consisted of paracentesis, whole body lymphoscintigraphy, lymphangio-MR, and lymphangio-CT (LAG-CT). The management of chyloperitoneum consisted initially of non-operative procedures (MCT diet, TPN, octreotide). Surgical treatment was performed in patients not responsive to conservative methods and involved different options using surgical and microsurgical approaches. Microsurgical techniques included chylousvenous shunts connecting chyliferous vessels and mesenteric veins. Fibrin glue or platelet gel injection at the site of the chylous leakage was also used to treat one case of refractory secondary chyloperitoneum. Patients were followed clinically and instrumentally (echography and labs tests) for 6 months to over 5 years. We found that LAG-CT was the primary diagnostic modality to provide precise topographic information concerning the site, cause, and extension of chylous pathology, all of which allowed proper planning of therapeutic procedures. Thirty-four patients did not have a relapse of the chyloperitoneum and 22 patients had a persistence of a small quantity of ascites with no protein imbalance. We observed early relapse of chylous ascites in 2 cases that required a peritoneal-jugular shunt leading to good outcomes. An accurate diagnostic study (above all LAG-CT) and a microsurgical approach proved to represent an effective management of chyloperitoneum refractory to non-operative treatment.
