title: Right lateral decubitus approach to a laparoscopic modified Hassab's operation.
abstract: BACKGROUND
  The lateral approach is the standard for laparoscopic splenectomy. However, when the modified Hassab's operation is performed laparoscopically, the patient is placed in the supine position and then the right semi-lateral or lateral decubitus position. Based on our experience with laparoscopic adrenalectomy and splenectomy, we laparoscopically performed the modified Hassab's operation with the patient in the right lateral decubitus position.
  
  
  METHODS
  Indications for the modified Hassab's operation for patients with portal hypertension in our institute include both gastric varices and hypersplenism resistant to endoscopic or radiologic procedures. We performed splenectomy and devascularization of the greater curvature and then dissected adhesions between the stomach, pancreas, and gastrohepatic ligament. With the patient in the right lateral decubitus position, the lesser curvature could be identified from both the ventral and dorsal sides.
  
  
  CONCLUSIONS
  For the modified Hassab's operation, as in laparoscopic gastrectomy, many operators select the supine position for lesser curvature devascularization and gastric vessel ligation. However, after sufficient adhesion dissection around the stomach, anatomical structures can be identified in the right lateral decubitus position. For this approach, gravity is not an issue on the dorsal side, and the lesser curvature can be observed from both the ventral and dorsal sides with the patient in the right lateral decubitus position. Laparoscopically performing the modified Hassab's operation with the patient in the right lateral decubitus position is a feasible method.
