Risk factors for the development of sterile fluid accumulations (PSSC) after endoscopic hernioplasty of inguinal hernias

Introduction. Inguinal hernioplasty is one of the most frequently performed operations in general surgery. Over the past decades, the introduction of minimally invasive technologies has shown advantages over traditional "open" techniques. However, one of the urgent problems remains postoperative fluid accumulation in the area of intervention. Despite the fact that such phenomena often have a favorable course, they can cause discomfort, slow down rehabilitation, and sometimes require additional interventions. Identification of PSSC risk factors is important for prevention and a personalized approach in the postoperative management of patients after inguinal hernioplasty. The purpose of the study. To determine the frequency of occurrence of postoperative sterile serous clusters (PSSCS) and to identify the factors influencing their development in patients after endoscopic inguinal hernioplasty. Materials and methods. The study was performed on the basis of the short-stay hospital of the O. M. Filatov Municipal Clinical Hospital № 15 of the Moscow Department of Health from January 1, 2024 to July 1, 2025. The analysis included patients who underwent laparoscopic inguinal hernioplasty using TAPP, TEP and their modifications. Results. In a comparative analysis of quantitative variables between groups with and without PSSC, statistically significant differences were found in the following indicators: hernial sac size, age, BMI, and type of hernia. Discussion. Inguinal hernioplasty remains one of the most common operations in general surgery, and in recent decades, endoscopic techniques such as TAPP and TEP have taken priority. Their benefits include reducing the intensity of postoperative pain, reducing recovery time, and reducing the risk of chronic pain. Conclusions. Postoperative sterile serous accumulations were detected in 46,1 % of patients after laparoscopic inguinal hernioplasty. The independent risk factors for their formation were overweight, oblique type of hernia and increased duration of surgery.
