SOLITARY SMALL BOWEL METASTASIS AFTER RESECTION OF BILE DUCT CARCINOMA

Abstract

Small bowel solitary metastases are a very rare occurrence and are more frequently recognized only in the presence of a severe complication, such as intestinal hemorrage or occlusion. We report the case of a 75 year-old man who was admitted with a recent history of mechanical ileus developed one year after the surgical removal of an endoscopically intubated carcinoma of the extrahepatic biliary tree (pT3 pN0 Mx). A solitary metastasis of the small bowel, 30 cm from the ileo-cecal valve, was excised during the emergency laparotomy and a side-to-side anastomosis was performed to reconstruct the intestinal continuity. Patient was, thereafter, discharged in the 9th postoperative day. Local recurrence and intrabdominal dissemination are often observed in patients treated for bilio-pancreatic carcinoma. Preoperative invasive (ERCP, FNA, PTBD, etc.) diagnostic procedures and surgical tumor manipulation are associated with a greater risk of metastasis implantation and intraabdominal dissemination. In accordance to the literature, the authors propose, in cases with resectable bilio-pancreatic neoplasms, the use of standard external low dose radiotherapy prior to any invasive diagnostic procedure and/or surgical removal.
