Intraoperative hypertonic saline irrigation preventing seroma formation and reducing drain secretion in extended...

Subcutaneous Seroma formation (SF) is commonly seen after abdominal wall Hernia surgeries and reconstructive surgeries due to large dissecting dead space and is associated with increased morbidity. SF is common particularly after big abdominal wall hernia repairs and its treatment can be challenging and long. Current prevention methods are not consistent and the treatment includes repeated aspirations and drains, both are associated with higher risk for infections. The purpose of this article is to present a novel and simple technique of Intraoperative Hypertonic Saline Irrigation (IHSI) to abdominal wall subcutaneous large dead space, which prevent postoperative SF and enables early drain removal due to reduced secretions.

Eight patients undergone the Extended Endoscopic Hernia & Linea Alba Reconstruction Glue surgery (eEHLARglue), for Ventral Hernias (VH) and Rectus Muscles Separation (RMS). An extensive Endoscopic 450cm² dissection free surface of the anterior Rectus fascia, is performed prior to Hernia dissection and closing of the RMS. It is followed by onlay mesh placing over the repaired Rectus muscles and the mesh is fused into the muscles by Fibrin Glue. The novel preventive method is based on Intraoperative Irrigation of the vast cavity through the two 10 mm JP closed system drains with 20 cc of NaCl 12% left at site for 10 min.

Our early results with all our patients show seroma prevention, lower secretion rate of 20 cc in 10 h and drain removal within 20-24 h.

IHSI enhance adhesion formation and reduce secretion rate in wide subcutaneous dissection space like in eEHLARglue, therefore enables early drain removal and prevent SF. As a result, reducing overall morbidity and hospitalization period, decreasing inconveniency and cost saving of multiple outpatient visits or additional surgery. This simple technique could be used in other potential postoperative SF surgeries. Further larger study with a longer follow up is advised.
