BACKGROUND: Pancreatic cancer is a common and deadly cancer, ranking as the 14th most common cancer worldwide and the 7th leading cause of cancer-related deaths. Advanced pancreatic malignancy frequently presents with biliary and gastric outlet obstruction and palliative open interventions are often required, especially in low-income countries where endoscopic surgical bypass methods are often unavailable. This study aimed to describe the demographic and clinical characteristics of patients undergoing biliodigestive bypass for pancreatic malignancy. METHODS: This was a hospital-based retrospective observational study at the tertiary hospital in northern Tanzania. We included 53 patients who underwent double or triple bypass surgery for pancreatic malignancy between January 2019 to December 2022 at Kilimanjaro Christian Medical Centre (KCMC), Tanzania. Data was collected from medical records, analyzing demographics, comorbidities, pre-surgery and surgery details, and post-surgery outcomes. Descriptive statistics were used to summarize continuous variables as mean with standard deviation and categorical variables as percentages. RESULTS: 53 patients were analyzed, with a mean age of 63.2 years and a male to female ratio of 1.03:1. Jaundice was the most common presentation (77.4%). Of the patients, 74.5% had comorbidities, and the majority (81.1%) were uninsured. 50.9% of patients had a length of hospital stay shorter than 5 days, and 88.3% resumed normal oral intake. Palliation failure was observed in 22.6% of patients. The median survival time for the entire cohort of patients was 65 days. Patients with palliation failure had a significantly shorter mean survival time than those without complications (14.17 vs. 90 days, p = 0.001). CONCLUSION: Bypass surgery remains a treatment of choice for palliating symptoms in patients with advanced pancreatic cancer. This study highlights the importance of prompt diagnosis of pancreatic tumors, especially in low-income countries, to achieve better outcomes.
