Full-thickness cholecystectomy with limited lymphadenectomy for gallbladder cancer.

Aggressive radical resection is advocated for gallbladder cancer. However, this is a disease of the elderly and some patients have comorbid disease(s) and/or a debilitated condition that may preclude such an aggressive treatment strategy. Here, we describe a minimum radical procedure for gallbladder cancer, termed as "full-thickness cholecystectomy with limited lymphadenectomy". This procedure comprises full-thickness resection of the gallbladder (cholecystectomy combined with removal of the entire cystic plate) and removal of the first-echelon lymph nodes (the pericholedochal and cystic duct node groups). Since 1992, 12 consecutive patients underwent the described procedure for tumors confined to the gallbladder wall and with no gross evidence of distant metastases/nodal disease, resulting in no in-hospital mortality or recurrent disease. The median overall survival was 229 months with a cumulative 5-year survival of 100%. In conclusion, the minimal radical resection procedure is safe and effective for early-stage gallbladder cancer. This less invasive procedure can be applied to patients with advanced age and/or comorbid disease(s), provided that the tumor is apparently confined to the gallbladder wall and has no gross evidence of distant metastases/nodal disease.
