Abstract
INTRODUCTION: Acute appendicitis (AA) is the most common cause of acute surgical abdomen. Complications from surgical appendectomy include intraabdominal abscess, bleeding, surgical site infections, ileus, and stump appendicitis (SA). This last one is one of the least common ones with a reported incidence of 1:50.000. METHODS: We present a case and review 132 cases of SA reported in the literature. Demographic and clinical characteristics were evaluated, as well as details of the surgical treatment. Categorical variables are presented as quantities and proportions, and continuous variables with median and interquartile range. Additionally, we calculate an incidence from 3 papers reported in the literature and our own. RESULTS: We analyzed 132 cases, 60.3 % were male with a median age at SA of 33 years. There was a wide range time interval between the episode of AA and SA from 1 day to 60 years. Initial open appendectomy was reported in 62 cases. From all the patients with SA 51 % reported complications. The median length of the appendiceal stump was 3 cm. The incidence of SA fluctuated between 0.22-1.37 in 1.000 cases of appendectomies. DISCUSSION: SA is usually underrated, and which are the risk factors for this condition are not clear. The data available suggest that a primary laparoscopic appendectomy is not related to SA, but the length of the stump left in the first surgery might be associated. The incidence of SA seems to be higher than the one reported of 1 in 50.000.
