[Rectal prolapse].

Rectal prolapse and rectal intussuception correspond to two stages of the same disease. Rectal prolapse is unusual but requires surgical treatment. Abdominal rectopexy is the most effective procedure but increases the risk of postoperative constipation. This risk decreases when the lateral sides are not touched during rectal dissection. The Delorme procedure is associated with a higher rate of recurrence and must be reserved for patients presenting a high risk of postoperative complications. Rectal intussuception is more frequent and is pathological only when arising in the anal sphincter. Rectal intussuception may lead to solitary rectal ulcer and has in this case to be treated by rectopexy. Rectal intussuception involvement in terminal constipation is not yet proved. Internal mucosectomy seems to be the best treatment for terminal constipation.

Radioimmunoguided surgery in colorectal cancer: a 6-year experience with four different technical solutions.

Intraoperative radioimmunodetection is a new staging technique for epithelial neoplasms. After intravenous injection, a radioimmunoconjugate compound (monoclonal antibody and isotope) attaches itself to the antigens expressed on the surface of neoplastic cells, causing them to emit gamma rays. Radioactivity is detected at the presurgical stage by immunoscintigraphy and intraoperatively with a gamma-detecting probe (GDP). In our experience, intraoperative tumor-to-normal-tissue (T/NT) GDP ratio counts > or =3:1 were considered positive radioimmunoguided surgery (RIGS) findings. We studied 52 colorectal cancer patients, 48 with primary lesions and 7 with relapses. Positive RIGS findings were obtained in 33 patients whose lymph node assessments were characterised by eight false positive identifications. In 10 patients, RIGS data yielded a more accurate staging of the disease. Unreliable RIGS findings were recorded in 15 patients: four injected with monoclonal antibody (MAb) B72.3 labeled with Iodine-125; five with MAb anti-carcinoembryonic antigen (CEA) labeled with 99mTechnetium (Tc); two with MAb B72.3 labeled with Indium-111; and three with MAb B72.3 labeled with Iodine-131 plus interferon-beta. In analysis, our experience did not permit definitive evaluation of the method's diagnostic and staging accuracy.

[Pleural plaque fibrosis: a clinical case].

A recent case of pleural plaques fibrosis in a worker exposed since 20 years to asbestos induced us to report our experience. A 52-year-old man was seen because of chest multiple opaques of soft tissue density without any symptoms. The CT-scan of thorax with i.v. contrast showed multiple lesions of diameter 0.5-4 cm on the posterolateral pleura bilaterally. FNAB of one lesion CT guided was not diagnostic. The pleural biopsy obtained at surgical exploration showed hyaline tissue, avascular, almost acellular, with calcifications and inflammation of low grade. The pleural plaques are generally multifocal and bilateral. They usually affect the parietal pleura. The connection between asbestos and plaques is firmly established. The pathogenesis is not well known. The pleural plaques fibrosis is a benign disease and a very common manifestation of asbestos exposure; it is not related to mesothelioma and it does not need any treatment. Because of the lack of symptoms it must be searched for in high risk subjects.

[The integrated radiosurgical treatment of rectal cancer].

The value of radio-surgical protocols in the treatment of advanced rectal cancer has been studied retrospectively. 21 patients operated between 1986 and 1990 fulfilling some criteria were considered for this study. They were 9 men and 12 women with rectal cancer Duke's stage B2-C; 16 were treated with preoperative radiotherapy (30-35 Gy), 5 were treated with postoperative radiotherapy (40-60 Gy). The operative procedures were 12 anterior resections and 9 Miles operations. The 5 years results were: a) cancer free survival 52%; 2 patients alive with relapse; 2 patients with non cancer related death (DIC, radiation enteritis); d) cancer related deaths 28%; e) local recurrence was observed (3 pts) only in association with metastatic disease; f) no isolated local recurrence was observed. Preoperative radiotherapy with 30-35 Gy is judged the preferred protocol for decreasing the rate of isolated local recurrence and for increasing the survival rate. Omental flap transposition plays an important role in the radio-surgical treatment of advanced rectal cancer.
