Incidental splenectomy associated with Nissen fundoplication.

Despite the relative frequency of iatrogenic splenectomy, its effect on postoperative morbidity and mortality remains controversial. This retrospective study compares the postoperative morbidity and mortality among 72 patients who underwent a Nissen fundoplication for esophageal reflux and 25 patients who had iatrogenic splenectomy and Nissen fundoplication. The age range in both groups was comparable. In the Nissen fundoplication (N.F.) group the average postoperative hospital stay was 9.4 days and in the Nissen fundoplication and splenectomy (N.F. + S.) group postoperative hospital stay was 15 days. In the N.F. group nine patients (12.5%) experienced significant postoperative morbidity in comparison to 36% in the N.F. + S. group (statistically significant p less than 0.1%). In the later group the complications were of a more severe nature. No mortality occurred in the N.F. group and one patient died in the N.F. + S. group. Iatrogenic splenectomy in this patient could well have been a prime factor in precipitating his demise. This retrospective study stongly supports the view that iatrogenic splenectomy in association with Nissen fundoplication adds considerably to postoperative morbidity.
