Does Pancreaticogastrostomy Decrease the Occurrence of Delayed Gastric Emptying After Pancreatoduodenectomy?

Area of Science:

• Gastroenterology
• Surgical Oncology
• Abdominal Surgery

Background:

• Delayed gastric emptying (DGE) is a frequent complication following pancreatoduodenectomy (PD).
• DGE negatively impacts patient recovery, prolongs hospitalization, and delays adjuvant therapy.
• Identifying risk factors for DGE is crucial for improving patient outcomes after PD.

Purpose of the Study:

• To investigate factors influencing the development of DGE after PD.
• To identify independent risk factors and protective measures associated with DGE post-PD.

Main Methods:

• Retrospective analysis of 257 patients who underwent PD between 2000 and 2012.
• Extraction of 46 variables from medical records to identify potential DGE predictors.
• Statistical analysis including univariate and multivariate assessments to determine factors associated with DGE, classified by the International Study Group of Pancreatic Surgery criteria.

Main Results:

• DGE occurred in 51.8% of patients (133/257).
• Independent risk factors for DGE included biliary fistula (OR 8.87), sepsis (OR 8.02), and intra-abdominal collection (OR 3.43).
• Pancreaticogastrostomy reconstruction was associated with a decreased incidence of DGE (OR 0.32).

Conclusions:

• DGE is significantly associated with postoperative intra-abdominal complications.
• Pancreaticogastrostomy demonstrates a protective effect against DGE following PD.
• These findings highlight the importance of managing complications and optimizing surgical reconstruction to mitigate DGE.
