RESUMO

OBJECTIVE: This study sought to investigate the impact of minimally invasive surgery (MIS) on recurrence and overall survival between patients with pancreatic head versus body/tail cancers. METHODS: The risk factors associated with recurrence and long-term outcomes were analyzed according to tumor location and operative modality. RESULTS: A total of 288 and 87 patients underwent surgical resection for pancreatic head cancer and body/tail cancer, respectively. The perioperative outcomes and histopathologic results were comparable in open and MIS approach in both head and body/tail groups. There was no difference in local or systemic recurrence patterns and disease-free and overall survival rates according to primary tumor location and surgical modality. During subgroup analysis by stage; however, patients with stage III pancreatic head cancer in the MIS group had a decreased disease-free survival compared with those in the open surgery group (p = 0.020). On multivariate analysis, MIS was not a risk factor of total or local recurrences. CONCLUSIONS: Recurrence patterns and overall survival rates of patients did not differ according to tumor location and surgical approach. However, patients with stage III pancreatic head cancer in the MIS group showed inferior disease-free survival relative to patients who underwent open surgery.

RESUMO

INTRODUCTION: Laparoscopic hepatectomies for centrally located tumors are classified as advanced and complex surgical procedures.1-3 Because of some limitations in robotic liver surgery,4,5 robotic central bisectionectomy has rarely been performed.6,7 We introduce useful tips for robotic central bisectionectomy in this multimedia article. METHODS: A 67-year-old male with a 4.4-cm-sized, hepatocellular carcinoma involving segments IV and VIII underwent robotic central bisectionectomy. This video demonstrates technique of determination of resection line,3 traction methods,8 effective use of robotic instruments for parenchymal transection, application of Pringle's maneuver, and indocyanine-green fluorescence image in robotic central bisectionectomy. RESULTS: Total operative time was 320 min and intraoperative blood loss was 200 ml without transfusion. The postoperative course was uneventful and the patient was discharged on the seventh postoperative day in good condition. Pathological assessment indicated that the mass was a hepatocellular carcinoma 4.5 cm in size with a surgical margin of 1.5 cm. CONCLUSIONS: Central bisectionectomy is one of the most demanding surgical procedures with long operative times. However, robotic central bisectionectomy can be safely performed with proper exposure technique and an appropriate combination of several useful technical tips.
