BACKGROUND AND OBJECTIVE: One of the complications of laparoscopic cholecystectomy is trocar incision hernia (TSIH: Trocar Site Incisional Hernia), which occurs almost exclusively in the navel area and could cause significant problems. The aim of this study was to evaluate the prevalence of hiatal hernia in laparoscopic cholecystectomy and identify the associated risk factors.

METHODS: This cross sectional study was done on patients who underwent laparoscopic cholecystectomy during one year in different hospitals of Babol. Information including age, gender, BMI, diagnosis prior to surgery, duration of hospitalization, duration of surgery, the thickness of the lining of the gallbladder, surgical site infection and umbilical hernia during 12 months follow-up for patients were confirmed and examined.

FINDINGS: Among 270 studied patients, there were 236 women (87.4%) and 34 men (12.59 %). Eleven patients (4.07%) during the 12-month follow-up; they had a hiatal hernia surgical site infection in the navel area (223.82-4.33: CI-95%, OR: 31.14) and BMI (60.18-1.72 CI-95%; OR: 10.21) were associated with increased incidence of inguinal hernias. There was no relationship between other variables and umbilical hernia.

CONCLUSION: According to the results of this study obesity and surgical site infections have been linked with an increased incidence of inguinal hernias.
