Specimens of the taenia from the sigmoid colon of female patients undergoing surgery for carcinoma of the rectum were studied histochemically and immunohistochemically for acetylcholinesterase (AChE) and for vasoactive intestinal polypeptide (VIP)-, substance P (SP)-, somatostatin (SOM)-, neuropeptide Y (NPY)-, calcitonin gene-related peptide (CGRP)- and Met-enkephalin (mENK)-immunoreactivity. Autonomic ganglia were observed on the serosal surface of the longitudinal muscle of the taenia. The subserosal ganglia contained SP-, mENK-, NPY-, SOM-, but not CGRP- or VIP-immunoreactive nerve fibres. In addition, they contained SP-, mENK- and NPY-, but not CGRP-, SOM- and VIP-immunoreactive nerve cell bodies (although CGRP- and VIP-immunoreactive nerve fibres were observed in the longitudinal muscle of the taenia). AChE-activity was found both in nerve fibres and nerve cell bodies in these ganglia. The greatest numbers of nerve cell bodies contained AChE, followed in decreasing order by SP, mENK and NPY. The possible function of the subserosal ganglia of the human taenia is discussed.

Carcinoembryonic antigen and some liver function tests (alkaline phosphatase, gamma-glutamyltranspeptidase, lactic dehydrogenase and cholinesterase) were evaluated in patients with primary colorectal cancer in order to define their role in the pre-operative detection of liver metastases. The records of 278 consecutive patients admitted to the Istituto Nazionale Tumori of Milan between January 1982 and December 1983 who were suffering from primary invasive colo-rectal cancer and who underwent laparotomy were retrospectively analyzed. At laparotomy, liver metastases were found in 38 pts (13.7%). Considering single tests, CEA was the most sensitive (71%); no single test was found to be reliably predictive, when the result was abnormal. On the contrary, the normal value of each test was associated with a good prediction. When we considered all the five tests together in the single patient their predictive value, when abnormal, proved to be quite good only if four or five results were abnormal. On the other hand, liver metastases in the presence of all normal tests were found only in two patients, so giving a negative predictive value of about 97%. So we conclude that, in the lack of an infallible imaging technique for liver evaluation, in the presence of all normal tests any other investigation on the liver could be avoided. However, when liver tests are pathologic, some other imaging technique should be performed in order to supply the surgeon with information about the extent and the spread of the metastases.
