CHICHIZOLA, Agustín et al. Differentiating between appendicitis with or without fecalith to change the therapeutic approach: Preliminary results. Rev. argent. cir. [online]. 2018, vol.110, n.4, pp.202-205. ISSN 2250-639X.

Background: Surgery is the traditional approach for patients with acute appendicitis. In the antibiotic era, new therapeutic paradigms are being proposed. The difference in the cause of appendicitis could establish the treatment of choice. Objective: to analyze if the presence of fecalith in an appendicitis can condition a surgical treatment or only with antibiotics. Material and methods: This observational analysis describes the intraoperative and pathological differences between patients undergoing surgery for acute appendicitis, divided into two groups according to the presence of fecalith or lymphoid hyperplasia as cause of the condition. The chi square test was used to compare the fecalith group versus the lymphoid hyperplasia group using a p value < 0.05. Results: The presence of fecaliths was more commonly associated with advanced stage of inflammation, presence of free peritoneal fluid (67% vs. 18% in the lymphoid hyperlasia group) and in more than one site (50% in the Douglas' pouch and 16.7% in the rest of the abdominal cavity). In this group, peritoneal fluid varied between serous and purulent and more appendiceal layers were involved (63.6% of mucous layer involvement in the lymphoid hyperplasia group vs. 16.7%, while serous compromise was more common in the fecalith group: 66.6% vs. 27.3%). Conclusions: Patients with acute appendicitis due to lymphoid hyperplasia could have lower rate of post-operative complications or could be good candidates for medical treatment with antibiotics alone, avoiding surgery.
