Relationship Between Obesity with Risk of Obstruction in Lateral Inguinal Hernia

Obesity is a state of excess weight due to the accumulation of fat in adipose tissue so that it can increase intra-abdominal pressure. Increased intra-abdominal pressure can increase the risk of obstruction in the lateral inguinal hernia. This study aims to determine the relationship between obesity and the risk of obstruction in patients with lateral inguinal hernia. This study uses an analytical research design with a cross-sectional approach by involving 152 respondents with a lateral inguinal hernia at Ari Canti General Hospital January 2018 – August 2019. The technique of this research is a consecutive sampling and data was obtained from the patient's medical records. The samples then analyzed with Chi-Square and stratification confounding factors with Mantel-Haenzel. From 152 respondents, 71 (46.7%) are obese and 81 (53.3%) are non-obese, 59 (38.8%) are with obstruction, 93 (61.2%) are without obstruction. There are relationship between obesity and the risk of obstruction in lateral inguinal hernia (p = 0.032, OR = 2.058, CI = 1.061-3.993). The analysis of Mantel-Haenzel shows that a history of heavy lifting (p = 0.125) and a history of alcohol (p = 0.077) as confounding. The Breslow-Day homogeneity analysis shows that the history of prostate enlargement (p = 0.003) as a confounding variable. Obesity has a relationship with the risk of obstruction in patients with lateral inguinal hernia, with a confounding variable history of weight lifting, alcohol history, and a history of prostate enlargement
