Management of high-output chylous ascites after D2-lymphadenectomy in patients with gastric cancer: a multi-center study.

BACKGROUND

This study aimed to propose treatment strategies for high-output chylous ascites (CA) developed after gastric cancer surgery.

METHODS

The data of patients with CA after gastric cancer surgery in three high volume Training and Research Hospitals between 2005 and 2015 were retrospectively evaluated.

RESULTS

Nine patients out of 436 gastrectomies were detected with CA. The mean amount of daily fistula output was 939 mL. Treatment consisted of cessation of oral feeding, total parenteral nutrition (TPN), somatostatin analogs administration, clamping and/or removal of the drainage tube, diuretic administration and diet therapy with medium-chain triglycerides (MCTs) alone or in combination. The mean fistula closure time and length of hospital stay were 23 and 24 days respectively. Hemopneumothorax developed during right subclavian vein catheterisation for TPN implementation in one patient. There was no mortality.

CONCLUSIONS

Combined cessation of oral feeding and TPN are usually used for treatment of CA as first-line treatment. However, TPN is no harmless. Although our data are limited they do allow us to conclude that diet with MCT's may use for medical treatment of CA as first-line.
