VILELA DESPOSORIO, Carlos David  and  CUSMA QUINTANA, Teresa Noemi. Association between appendiceal obstruction and the morphological type of acute appendicitis. Rev. gastroenterol. Perú [online]. 2015, vol.35, n.1, pp.32-37. ISSN 1022-5129.

Objective: Determine if the morphological type of appendicitis is associated with the type of appendiceal obstruction. Material and methods: A descriptive, observational and prospective study was conducted at the Hospital Belén of Trujillo, during the year 2013. Results: There were 398 cases that took part of the study. A 54% of patients had between 10 and 29 years old, 55.5% were males and 44.5% females. The average length of the appendix was 7.19 ± 1.6 and 1.14 ± 0.5 cm diameter. Cecal appendices with diameter less than 0.8 did not show acute inflammation. A 16.2% of the appendices were perforated. In 43% a obstruction was evident in the appendiceal lumen, which corresponded to 56.3% for the presence of fecal bolus, 29.9% to bend appendiceal and 4.8% to faecolith. In 5.4% of cases a parasite E.vermicularis was found. A 81.4% of the appendices that had a fecal bolus or faecolith, had severe suppurative appendicitis, gangrene and / or perforation while only 55.4% of the appendices that had hyperplasia or bending presented the most severe morphological types (p <0.05). Conclusions: The appendices that had a fecal bolus or a faecolith had a morphological type of appendicitis more severe than those who had other obstructions type. Therefore, there was a statistically significant association between the morphological type of appendicitis and the type of obstruction.
