Cattell-Braasch maneuver combined with local hypothermia during superior mesenteric artery resection in pancreatectomy

BACKGROUND: The recent development of new neo-adjuvant treatment regimens associated with a higher success rate of down-staging has increased the interest of pancreatic surgeons on the role of extended surgery for patients affected by locally advanced pancreatic cancer. Pancreatectomy together with resection of the portal/superior mesenteric vein is considered nowadays standard of care for patients affected by pancreatic cancer. However, the resection of major abdominal arteries is still debatable. In particular, the short- and long-term results after resection of the superior mesenteric artery (SMA) remain controversial and only few cases have been described in literature. The present paper describes a new, quick, and easy technique for resection of the SMA. CLINICAL CASE: A 71-year-old patient affected by IPMN cancer with infiltration of the SMA received FOLFIRINOX-based neo-adjuvant treatment. After 4 months of treatment, the patient underwent total pancreatectomy with en bloc resection of the SMA and direct end-to-end anastomosis. The vascular resection was performed combining a complete Cattell-Braasch maneuver with local bowel hypothermia in an attempt to avoid graft interposition by facilitating an end-to-end anastomosis and to reduce the warm ischemia time. The post-operative course was uneventful and the patient was discharged 8 days post-operatively.
