Metastatic Small Bowel Perforation Caused by Intrahepatic Cholangiocarcinoma in a Patient with Combined Hepatocellular-cholangiocarcinoma

Advances in chemotherapy and radiation therapies for malignant tumors have resulted in the identifications of various novel features of intestinal metastasis. The common causes of small bowel metastasis are malignant melanoma and lung cancer, and this has also been rarely reported to uterine cervical cancer, malignant lymphoma of the larynx, malignant lymphoma of soft palate, and hepatocellular carcinoma (HCC). The Combined HCC-cholangiocarcinoma (HCC-CC) is a rare primary liver malignancy, and is composed of cells with the histopathological features of both HCC and CC, but metastatic small bowel perforation by CC in a patient with combined HCC-CC has not been reported previously. The authors describe the case of a 51-year-old man with a metastatic small bowel perforation caused by an intrahepatic CC in combined HCC-CC with a review of the literature.

Laparoscopic Management of Appendiceal Intussusception Caused by Fecaliths

Appendiceal intussusception is a rare condition of abdominal pain. It develops as a result of various anatomic or pathologic conditions, such as polyps, worms, carcinomas, mucoceles, or fecaliths. Furthermore, an accurate preoperative diagnosis of appendiceal intussusception may be difficult. However, recently developed radiologic modalities, such as multidetector CT and laparoscopy, can considerably aid preoperative diagnosis and provide a means of adopting optimal minimally invasive surgery. Here, the authors describe the case of a 30-yr-old woman with the clinical features of acute appendicitis, who was preoperatively diagnosed as having appendiceal intussusception with fecaliths and who was managed by using a laparoscopic partial cecectomy.
