Coloepiploic mobilization during left radical nephrectomy for renal cell carcinoma is indicated to reduce the risk of iatrogenic splenectomy

Objectives To determine whether coloepiploic mobilization (CEM) is indicated to reduce the incidence of iatrogenic splenectomy during left radical nephrectomy for renal cell carcinoma. The incidence of iatrogenic splenectomy during a left nephrectomy is estimated to be between 1.4% and 24%. In a recent study, we reported that the incidence of iatrogenic splenectomy was 8% during a left nephrectomy performed for renal cell carcinoma through a transperitoneal anterior subcostal incision. Methods A left radical nephrectomy was performed in 233 consecutive patients for renal cell carcinoma through a transperitoneal anterior subcostal incision with a CEM procedure in which the left colonic flexure was completely detached from the epiploa. Perioperative and postoperative complications, including splenic injury, were noted in a database. The mean patient age was 51.3 years (range 21.3 to 90.2). The mean tumor size was 58 mm (range 15 to 230). Results An iatrogenic splenectomy was required in 3 patients, and in 1 patient, a splenic injury was treated conservatively. The incidence of iatrogenic splenectomy accompanying left radical nephrectomy was 1.3%. The mean operative time was 120 minutes (range 80 to 240). The mean time to normal gut motility was 3.4 days (range 2 to 11) and to discharge from the hospital it was 9.3 days (range 6 to 19). Regarding CEM, we did not observe any significant abdominal complications. Conclusions The incidence of iatrogenic splenectomy during a left radical nephrectomy through a transperitoneal anterior subcostal incision may be reduced by performing the technique of CEM.
