Background: Laparoscopic surgery is arguably the treatment of choice for patients undergoing elective splenectomy; however, for those patients with massive splenomegaly, laparoscopic surgery may prove difficult.
Patients and methods: 6 years' experience of elective splenectomy was reviewed, in particular looking at the outcome of laparoscopic splenectomy in relation to the degree of splenomegaly.
Results: The conversion rate for laparoscopic splenectomy on patients with spleens weighing less than 1 kg was 0% whereas the conversion rate for those with spleens weighing more than 1 kg was 60%. In addition, a good correlation between both operative time and intra-operative blood loss in relation to splenic weight was observed. Open splenectomy on patients with spleens weighing more than 1 kg reduced the operative time and intra-operative blood loss without affecting hospital stay.
Conclusions: Laparoscopic splenectomy is the method of choice for elective splenectomy in patients with splenic weight estimated to be < 1 kg; however, the operation takes longer, there is a high risk of conversion and there is an increase in blood loss/morbidity associated with massive splenomegaly (spleen > 1 kg) if splenectomy is attempted laparoscopically.
