Preservation of the pylorus in pancreaticoduodenectomy.

Further clinical observation and laboratory evaluation will be necessary before we can recommend this modification of the usual technique of pancreaticoduodenectomy to preserve the pylorus and distal part of the stomach in patients in whom the resection is performed for benign disease or for carcinoma of the distal part of the duodenum. However, we believe that the early results in the two patients described are encouraging.
