Duodenum-preserving pancreatic head resection: A retrospective analysis of the Hamburg Modification.

Background: Chronic pancreatitis remains a challenging inflammatory disease, causing progressive, irreversible fibrosis of the pancreatic parenchyma. Several surgical options for treatment have been established, but duodenum-preserving pancreatic head resections seem to be the most favorable option other than pancreatoduodenectomy. The aim of this retrospective analysis is to evaluate the outcomes of the Hamburg modification of duodenum-preserving pancreatic head resections.

Methods: We retrospectively evaluated-for long-term outcomes concerning pain control, quality of life, and symptom control-500 consecutive patients suffering from painful chronic pancreatitis who had undergone the Hamburg modification of the duodenum-preserving pancreatic head resection. Additionally, the patients were compared with a database of 104 patients who underwent duodenum-preserving pancreatic head resections according to Beger or Frey.

Results: After a mean follow-up of 10 years, overall survival was 90% in those patients having undergone the Hamburg modification. Regarding analgetic medications, the median pain score for frequency of pain attacks, measured by a visual analog scale and inability to work, was 0 (0-100), and the global quality of life revealed a median of 92 (0-100). In addition, we found that a high rate of patients continued consuming alcohol after the operation (37.9%). The rate of redo surgery owing to the recurrence of chronic pancreatitis was 7.6% after this Hamburg modification.

Conclusion: Duodenum-preserving pancreatic head resections provide adequate outcomes in terms of pain control, quality of life, and symptom control. In this retrospective analysis, the Hamburg modification was found to be a good alternative to other forms of duodenum-preserving pancreatic head resections. The choice of a certain modification of the duodenum-preserving pancreatic head resection may depend on the surgeon's expertise and the individual needs of the patient.
