[Drainage of liver abscess by "mini-hepatotomy"].
We have developed a a "mini-hepatotomy" technique to prevent rupture of large superficial liver abscesses.


OBJECTIVE
The purpose of this report is to describe our results using this technique.


METHODS
Data was extracted from the files of 40 patients hospitalized in our department for liver abscess from January 2000 to June 2005. Antimicrobrial therapy including metronidazole was administered to all patients and was the sole treatment in two. Additional treatment included laparotomy for ruptured abscess in 4 cases, pleural drainage for rupture in the right pleural cavity in one, and "mini hepatotomy" in 33. This study includes the 33 patients who underwent mini-laparotomy. There were 30 men and 3 women with a mean age of 38 years. The mean delay for consultation was 51 days.


RESULTS
Liver abscess was classified as amoebic abscess in 28 cases and pyogenic abscess in 5. The mean diameter of the abscess was 11.5 cm. The abscess was located in the right lobe in 21 cases and left lobe in 12. The mean quantity of liquid drained from the abscess was 1060 mL. Outcome was favorable in 28 cases (success rate: 84.8%). In the remaining 5 cases abscess persisted after drain removal including two that required a second drain procedure and three that resolved after medical treatment. The failure rate was 6% (2/33). No patient died.


CONCLUSIONS
Large size and superficial location are risk factors for rupture of liver abscess. Drainage is warranted in patients at risk for this complication. The results of this study show that our "mini-hepatotomy" drainage technique has a high success rate and can achieve good results.
