HighlightsThe localization of small intestine sources of obscure gastrointestinal bleeding is a challenge.The use of indocyanine green (ICG) is effective in aiding intraoperative localization.The ICG fluorescence imaging can visualize the lesion as an arteriovenous malformation.
Guest Editor's Introduction: This paper was originally presented at the 9th congress of ASAIO in April 1963. The original paper was printed in Volume IX of Trans. Soc. Artif. Int. Organs 1963, pages 358–362. It was reprinted with permission in Therapeutic Apheresis, Volume 4, Issue 1, 2000 as a millennium project of the International Society for Apheresis. This paper describes for the first time a hybrid artificial live and extracorporeal circulatory system composed of a specially developed high permeable gel type cellophane membrane. This membrane separated the patient's blood and the metabolic fluid in which freeze‐dried canine liver granules were contained. Carbohydrate metabolism and ammonia detoxification were maintained in this metabolic chamber, eventually helping the patient's metabolic functions. In addition to experimental studies, four clinical studies were briefly reported.
We report a rare case of colonic metastasis from primary carcinoma of the lung. A 59-year-old man who underwent pulmonary surgery for lung cancer was referred to our hospital in June 2007. The patient complained of abdominal pain, and barium enema examination at another hospital had demonstrated a descending colon tumor. Postoperative histopathological and immunohistochemical findings indicated that the tumor was a colonic metastasis of lung cancer. Three months postoperatively, the cancer had metastasized to the brain, and the patient underwent radiotherapy. He survived for more than 1 year after colonic surgery. Clinically apparent metastases from lung cancer to the colon are rare, and in the 50 Japanese cases retrospectively investigated here, the prognosis was poor.
INTRODUCTIONColorectal obstructive endometriosis is relatively rare in Japan and its differentiation from malignancy is often difficult. We report a case of rectal obstructive endometriosis.PRESENTATION OF CASEA 37-year-old woman was referred to our hospital with a suspected ileus. Her chief symptoms were left lower abdominal pain and vomiting. Colonoscopy showed an intraluminal mass of redness in the upper rectum. A proctectomy was performed because of the bowel obstruction. The rectum was filled with an intraluminal mass measuring 5 cm × 4 cm, and endometriosis was diagnosed pathologically.DISCUSSIONA preoperative diagnosis of colorectal obstructive endometriosis is often difficult because of the lack of definite diagnostic, clinical, sonographic, or radiological findings that are characteristic of this disease. Medical treatment is not always effective for colorectal obstructive endometriosis, and surgery is often performed.CONCLUSIONColorectal obstructive endometriosis should be considered as a differential diagnosis in cases of various gastrointestinal symptoms in women who are of reproductive age.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
