The value of a laparoscopic interval appendectomy for treatment of a periappendiceal abscess: experience of a single medical center.

BACKGROUND: Interval appendectomy has been known to be an effective and safe treatment for a periappendiceal abscess, but there is no study on a laparoscopic approach for the treatment of a periappendiceal abscess. The aim of this study is to investigate the value of laparoscopic interval appendectomy. MATERIALS AND METHODS: We retrospectively studied 56 patients who had been admitted due to a periappendiceal abscess to Chungbuk National University Hospital from July 2005 to June 2010. Fifteen patients underwent an initial conservative treatment and interval appendectomy. Medical records were reviewed for the postoperative hospital course such as complications, time of initiation of diet, time since stopping antibiotics, symptoms' relief period, and length of hospital stay. RESULTS: All patients received initial conservative treatment [percutaneous drainage insertion (1 case failed) and intravenous antibiotics], and the initial length of hospital stay was 11.6±4.3 days. Percutaneous drainage was removed a mean of 21.7±9.4 days after the initial treatment. Interval appendectomy was performed at a mean of 64.0±17.8 days after initial admission. The duration of use of intravenous antibiotics was a mean of 4.1±1.8 days after laparoscopic interval appendectomy. The complication rate was 1 (6.7%) and the open conversion rate was 1 (6.7%). CONCLUSIONS: Our study revealed that initial conservative treatment and laparoscopic interval appendectomy represented a feasible and effective treatment for patients with a periappendiceal abscess.

Laparoscopic appendectomy is a safe and beneficial procedure in pregnant women.

BACKGROUND: Appendectomy is the most common nongynecologic surgery performed during pregnancy. Pregnancy is no longer considered an absolute contraindication for laparoscopic procedures. Laparoscopic appendectomy (LA) is a safe, effective, and beneficial procedure for the treatment of acute appendicitis. However, limited data are available regarding the safety and feasibility of LA during pregnancy. METHODS: Between May 2005 and May 2009, 20 patients with clinically suspected appendicitis in pregnancy underwent LA at Chungbuk National University Hospital. Clinical data collected retrospectively included demographic information. We compared maternal age, gestational age, operation time, anesthetic time, surgical complications, length of hospitalization, and final outcome of pregnancy. RESULTS: All the 20 patients who underwent LA did not need a conversion. Mean maternal age was 28.1 years (range, approximately 20 to 35 y), gestational age was 15.4 weeks (range, approximately 6 to 30 wk), mean operation time was 45.5 minutes (range, approximately 25 to 90 min), mean length of hospital stay was 4.7 days (range, approximately 2 to 11 d). Fifteen of 20 pregnant women delivered healthy term infants and 5 women have kept a healthy pregnancy. CONCLUSIONS: Our data support the accumulating evidence that LA is a safe and feasible procedure for the treatment of acute appendicitis in all trimesters of pregnancy. Close maternal and fetal monitoring is essential during and after the operation.
