Abstract
We describe the technical details and evaluate the safety, feasibility, and usefulness of a combined lateral and abdominal (CLA) approach for laparoscopic resection of liver segments 7 and 8. Laparoscopic resection of lesions in the posterosuperior area of segments 7 and 8 is technically challenging, and currently there is no standardized laparoscopic approach. Through review of a prospectively maintained database, we identified 44 patients who underwent laparoscopic resection of lesions in segment 7 or 8. Twenty-five patients required the CLA approach because their lesions were more posterosuperior and intraparenchymal; 19 patients underwent resection with a regular abdominal-only approach of more accessible anteroinferior lesions. We reviewed operative details and video footage of these operations and compared the outcomes of the 2 groups. In the group treated with the CLA approach, deep location was more frequent (88% vs 42%; P = 0.035), median tumor diameter was larger (24.5 mm vs 15 mm; P = 0.114), and the median weight of the excised parenchyma was greater (56.5 g vs 23 g; P = 0.093). Median operative time was longer in the CLA approach group (217.5 minutes vs 165 minutes; P = 0.046), but blood loss, rate of conversion to open surgery, surgical margin status, morbidity, and mortality were similar between the 2 groups. The CLA approach permits safe laparoscopic resection of lesions in the posterosuperior area of segments 7 and 8, allowing surgeons to overcome the difficulties of limited visualization and access to the target lesions.Keywords
