Abstract
Pancreatico-duodenectomy is a complex operation that is becoming more common as treatment for both malignant and benign diseases of pancreas. The postoperative mortality in non specialized centers often exceeds 20% but is around 6% or less in specialized centers. However, the morbidity rate even in specialized centers is still high between 30-60 percent. Delayed gastric emptying is a common complication that rarely leads to mortality or additional invasive procedures, but it can add tremendous expense and hospitalization to affected patients’ care. Both the classic and the pylorus-preserving Whipple have this associated morbidity.
DGE occurs in 25% to 70% of patients undergoing PD with an average incidence of 30%. The wide range of occurrence of DGE in the different studies can be explained partially by differences in the definition of this complication. A wide range of causative mechanisms has been proposed to be the culprit for the occurrence of DGE. The ill-defined etiologies in combination with the absence of a uniform definition for DGE comprise the basis of the existing debate. In addition, as a result of the tendency most surgeons have to preserve anatomic and functional structures in an attempt to improve the quality of life of the patient, various modifications of PD have emerged that make comparative studies difficult to interpret.
With these general consideration in mind this work aimed at investigating the effect of hemigastrectomy in Whipple’s resection in hope of the stomach will be conduit for food instead of a reservoir; such modification may overcome the famous postoperative morbidity of delayed gastric emptying after Whipple’s resection with antrectomy.
