Laparoscopic splenectomy using pneumoperitoneum or gasless abdominal wall lifting: a 15-year single institution experience.

INTRODUCTION

Laparoscopic splenectomy using pneumoperitoneum has been performed since 1992. The gasless abdominal wall-lifting method for laparoscopic splenectomy was introduced as an alternative. This retrospective study was undertaken to compare results using the two techniques.

METHODS

Between 1995 and 2010, 54 patients underwent laparoscopic splenectomy at a single institution; 30 underwent the procedure using the gasless technique and 24 using pneumoperitoneum. There were no significant differences between the two groups regarding age, sex or BMI, but more patients underwent concurrent operations in the pneumoperitoneum group. The abdominal wall-lift system with subcutaneous K-wires was used for the gasless method.

RESULTS

Intraoperative blood loss was similar in the two groups (193.0 ± 196.7 mL gasless, 217.3 ± 296.6 mL pneumoperitoneum; P > 0.05), but operative time (182.1 ± 92.1 min, 135.1 ± 46.1 min; P < 0.05), and resected spleen weight (306.1 ± 297.7 g, 138 ± 81.0 g; P < 0.05) were significantly different. In the gasless group, additional procedures included conversion (n = 1), mini-laparotomy (n = 2), and CO(2) insufflation (n = 2). Excluding the concurrent living-related kidney donor patients, hospital stay was similar (6.9 ± 2.5 days, 6.3 ± 2.0 days, P > 0.05).

CONCLUSION

Although gasless laparoscopic splenectomy is feasible, there are disadvantages, particularly the restricted operative working space in some patients. These results suggest that either technique may be used on an individual basis in patients undergoing laparoscopic splenectomy.
