[Complicated appendicitis during pregnancy]. / Oslozhnennye formy ostrogo appenditsita u beremennykh.

AIM: To analyze incidence, diagnosis and treatment of complicated appendicitis in pregnant women and to determine the optimal surgical approach. MATERIAL AND METHODS: Retrospective cohort analysis included 338 pregnant women who underwent appendectomy in 2012-2016. Complicated appendicitis (abscess, local or common peritonitis and their combinations) was diagnosed in 22 cases. The main perioperative variables (duration of the disease, time of surgery, length of hospital-stay, incidence of wound complications, etc.), clinical and laboratory symptoms, results of ultrasound diagnosis and pregnancy outcomes were analyzed. Statistical analysis was carried out in Stata 14.2. Fisher's exact test, Mann-Whitney-Wilcoxon's U-test and multivariate regression analysis were used to compare data. RESULTS: The incidence of complicated appendicitis in pregnant women was 6.51%. There are no clinical symptoms which would be significantly more common in complicated appendicitis during pregnancy. Complicated course prolongs surgery and hospital-stay, however duration of postoperative analgesia depends on surgical technique as a rule. There were 27% of laparoscopic interventions that is lower compared with women with uncomplicated appendicitis. The percentage of conversions was higher too. CONCLUSION: Clinical diagnosis of complicated appendicitis during pregnancy even by using of ultrasound is not satisfactory and requires the involvement of other objective methods, such as MRI. Laparoscopic intervention is not contraindicated in pregnant women with complicated appendicitis and determine better treatment outcomes than open surgery.
