Outcomes of Antibiotic Therapy for Uncomplicated Appendicitis in Pregnancy

OBJECTIVE: The aim of the present study is to determine the feasibility and safety of antibiotics for uncomplicated simple appendicitis in pregnancy. METHOD: We conducted a 6-year prospective observational study on 20 pregnant women in whom uncomplicated simple appendicitis (appendiceal diameter <= 11 mm and with no signs of appendicoliths, perforation, or abscess) was radiologically verified and managed with a 4-day course of antibiotics. Treatment failure rate, defined as the need for an appendectomy during hospitalization and recurrence in the follow-up period (median 25 months), and maternal or fetal complications during the pregnancy were evaluated. RESULTS: Mean age of patients was 33.4 years, and gestational age was 17.8 weeks. Three patients failed to respond to antibiotic therapy during hospitalization and underwent subsequent appendectomy (2 suppurative and 1 perforated appendicitis). There was 1 wound infection postoperatively. During follow-up, 2 patients during their ongoing pregnancy experienced recurrence at 3 and 6 months post-treatment, and a new course of antibiotics was determined. Patients also experienced recurrence at 8 and 10 months post-treatment and underwent appendectomy. Treatment failure occurred in 5 patients (25%) with no fetal complications during the pregnancy. CONCLUSIONS: Antibiotic therapy for uncomplicated appendicitis in pregnancy may be a feasible treatment option without severe maternal and fetal complications. (C) 2017 Elsevier Inc.
