  • Title: [Implantation metastases following laparoscopic cholecystectomy in gallbladder carcinoma].
    Author: Buhr J, Hürtgen M, Heinrichs CM, Graf M, Padberg WM.
    Journal: Dtsch Med Wochenschr; 1996 Jan 19; 121(3):57-61; discussion 61-2. PubMed ID: 8565811.
    Abstract:
    HISTORY AND CLINICAL FINDINGS: A 66-year-old woman was known to have had cholecystolithiasis for at least 4 years. Laparoscopic cholecystectomy was performed at another hospital where histological examination surprisingly revealed middle-grade differentiated carcinoma of the gall-bladder (pT2, G2). A nodular metastasis of the gall-bladder carcinoma was noted on the abdominal wall 3 months later and excised. Lymph-vessel carcinomatosis was already present. The patient again noticed a tumour in the right mid-abdomen and a further tumour was palpated in the epigastrium 5 months after the operation. INVESTIGATIONS: Laboratory and tumour-marker (CEA, CA 19-9) tests were unremarkable, while sonography and computed tomography were highly suspicious for abdominal wall metastases in the epigastrium and right mid-abdomen. TREATMENT AND COURSE: Both metastases were excised. Laparotomy revealed tumour recurrence in the old gall-bladder bed, as well as extensive peritoneal carcinoma. Two months after the operation she developed jaundice, caused by tumour compression of the choledochal duct. An expanding stent was inserted into the stenosed section of the duct. The patient died 13 months after the first operation from the underlying malignancy with multiple liver metastases and malignant ascites. CONCLUSIONS: Indications for minimally invasive surgery in malignant tumour should be narrowly defined. Because tumour seeding is possible after laparoscopic cholecystectomy with incidentally found carcinoma extensive re-excision should be performed.
