A Case Report of Duodenal Malignancy and Its Management With Pancreaticoduodenectomy.

Gastrointestinal malignancies, most specifically duodenal malignancy, are uncommon in the population; however, they are tricky to manage because the lesions are diagnosed at a late stage and located in a complex area. This case report focuses on a patient who was diagnosed with a second (descending) part of the duodenum (D2) malignancy; the tumour was localised at the second part of the duodenum, and the management of this patient was through the Whipple procedure or pancreaticoduodenectomy. The patient complained of stinging abdomen pain. Diagnostic examination comprised of CT and biopsy proved the presence of a malignant tumour originating from the D2 area. The tumour's characteristics and the patient's general health status are determined by using Whipple's procedure. Post-operative management entails the use of IV antibiotics, analgesics, multivitamins and nasojejunal (NJ) tube feeding. The case also expounds on the consequences of a multimodal treatment strategy, meticulous planning of the surgical procedure, and adequate post-operative management of D2 malignancies. These data may shed some light on the peculiarities of duodenal cancer management with the Whipple procedure; nonetheless, early diagnosis and proper management should remain the primary goals.
