Study on the relationship between right inguinal hernia (RIH) and appendectomy with laparoscopic and open surgery by McBurney incision

Appendectomy is performed by open surgical technique (McBurney) and laparoscopy. Laparoscopic method is used in 58% of US appendectomies. Incisional hernias, occur to the nearby of surgical site due to previous surgery. Around 10-15% of abdominal Incisions lead to Incisional hernia. Considering the lack of new studies in this area and that no study has compared this two surgical techniques, we decided to determine the prevalence of right inguinal hernia (RIH) in patients undergoing open and laparoscopic appendectomy. All patients undergoing appendectomy referred to Khorramabad Shohada hospital were studied in a Cross Sectional Study from 2012 to 2014. The sample size was 264 patients in two groups of McBurney (136 patients) and laparoscopic (128) were enrolled with the inclusion criteria and randomly. Questionnaires were completed based on demographic information and questions related to the study by patients file, visiting and making call. For statistical analysis chi-square test and logistic regression for multivariate (at a significance level of less than 0.05) were used. Of total 162 person (4.61%) were men and 102 (6.38%) were female. The average age of the participants was 32 ± 9.10 years. Appendicitis leading to abscess in 5.4%, suppurative appendicitis in 8.70%, Phlegmon in 9.18% and perforated appendicitis were seen in 7.5% of the patients respectively. Right inguinal hernia in McBurney group were 6.6% (n = 9) and in laparoscopy group were 6.1% (n = 2). Despite the high incidence of hernia in McBurney group but there was no statistically significant relationship between the type of surgical procedure, type of appendicitis and the RIH. Other studies with larger sample sizes are recommended for further investigation.
