BACKGROUND: Portal Annular Pancreas (PAP) is a relatively uncommon entity with 4% reported incidence. Pancreaticoduodenectomy is challenging in cases with PAP and is associated with higher postoperative pancreatic fistula rate and overall morbidity. PAP is classified according to the pattern and location of fusion around the portal vein as-supra-splenic, infra-splenic & mixed fusion type. Also, the ductal anatomy can vary as pancreatic duct present only in the ante-portal portion or only in the retro-portal portion or ducts in both ante and retro-portal portion. At present, ideal surgical strategy is not defined as per the PAP types.
METHODS: The case demonstrated in the video presented with a localized, large duodenal mass with type IIA PAP (supra-splenic fusion with both ante and retro-portal ducts) detected on the preoperative triphasic CT scan. To achieve a single pancreatic cut surface with a single pancreatic duct for anastomosis, an extended pancreatic resection was performed using meso-pancreas triangle approach.
RESULTS: Patient had a smooth intraoperative course & the postoperative recovery was also uneventful. Pathology reported pT3 duodenal cancer with negative margins and uninvolved lymph nodes.
CONCLUSION: A preoperative knowledge of PAP and its various types is extremely important in order to tailor intraoperative management, specially of the retro-portal portion. In patients with retro-portal duct or both ante and retro-portal ducts (as the case presented in the video), an extended resection is recommended to mitigate postoperative pancreatic fistula.
