Abstract:
Objective To investigate the risk factors of seroma in patients with unilateral oblique inguinal hernia after laparoscopic transection of the hernia sac through anterior abdomen. Methods From August 2015 to August 2020, 100 patients with unilateral indirect inguinal hernia treated by laparoscopic transection of hernia sac through anterior abdominal peritoneum of the hernia sac in our hospital were selected as the research object. The patients were divided into the seroma group (21 cases) and the non-seroma group (79 cases) according to the complications of seroma. The general data of the two groups were compared. Multivariate Logistic regression analysis of independent risk factors for postoperative seroma. Nomogram model was constructed based on risk factors. Receiver operating characteristic curve and calibration curve were used to evaluate the prediction efficiency of the model. Results Postoperative seroma occurred in 21% of patients. Multivariate Logistic regression analysis showed that taking anticoagulant, course of disease >1 year, hernia type Ⅲ/Ⅳ, hernia sac diameter≥5 cm, mesh glue fixation and Neutrophil to lymphocyte ratio (NLR) ≥2 were independent risk factors for postoperative seroma (P<0.05). Calibration curve and ROC curve showed that the model had good discrimination and accuracy. Conclusion Anticoagulant use, course of disease, hernia classification, diameter of hernia sac, mesh fixation method and NLR are related to seroma after Laparoscopic transection of hernia sac through anterior abdominal peritoneuml. Clinical attention should be paid to these factors and corresponding preventive measures should be formulated in time.
