The authors report two cases of colonic intussusception in the adult protruding from the anus--or colon-anal intussusception--, not due to a tumor. The first case was a chronic ileo-caeco-colique intussusception, the second case was an acute colo-rectal intussusception. Colo-anal intussusceptions are very rare: less than twenty cases have been described since 1925 in adults. The absence of a tumor origin in our cases represents a special feature, as only three other similar cases have been described. The surgical treatment in both cases was primary colonic resection without colostomy. The surgical treatment of the first case was subtotal colectomy with ileo-rectal anastomosis. The second case was primarily reduced by barium enema which allowed optimal secondary surgical resection of a prepared colon.

Ultrasound examination was performed on 307 patients admitted to Herlev Hospital, Copenhagen, for suspicion of a pelvic tumor. Of these, 194 were operated on, 38 (19.6%) having a malignant tumor and 156 with benign conditions. A solid tumor was suspected in 72 patients on whom intravenous pyelography, barium enema, cystoscopy and rectoscopy were performed, although 11 did not undergo an intravenous pyelography and 12 did not undergo a barium enema. Intravenous pyelography, barium enema, rectoscopy and cystoscopy very seldom gave unsuspected information and never changed the indications for operation. Ultrasound examination of the kidneys, urinary tract, bowel system, liver and retroperitoneum as a complementary investigation to the gynecologic examination of the pelvic tumor gave the same information as did the barium enema, intravenous pyelography, rectoscopy and cystoscopy. Therefore, we conclude that these investigations should be carried out only in patients with symptoms from the urinary tract or the bowel system. Instead, we suggest that ultrasound examination of a pelvic mass also include an examination of the kidneys, urinary tract, bowel system, liver and retroperitoneum.

The clinical and pathological manifestations of a case of carcinosarcoma of the esophagus are reported. Barium swallow and endoscopy revealed a polypoid mass in mid esophagus. The tumor was large, pedunculated, covered by smooth mucosa with some erosions. Histologically the tumor was composed of a mixture of invasion keratinizing cells and intermingled bundle of spindle shaped cells resembling fibrosarcoma. The tumor was removed with surgery and did not show submucosa infiltration. It was not detected any metastasis or local recurrence during the 12 months follow-up period. The diagnosis was made by an endoscopic partial polypectomy. We conclude that partial polypectomy may be of value in preoperative diagnosis of esophageal polypoid mass.

Enhancer duplication in the long terminal repeat of feline leukemia virus (FeLV) was examined in primary cells from naturally FeLV-infected cats with various neoplastic and nonneoplastic diseases using the polymerase chain reaction. In all cases, a 170-bp band, corresponding to a standard exogenous FeLV with one copy of enhancer, was detected. Repeated enhancer sequences were found in all 8 cases of thymic-form lymphosarcoma, in some cases of lymphosarcoma of other forms (3/8) and myeloid tumors (2/3), and in only 1 of 6 cases with nonneoplastic diseases. The copy number of FeLV proviruses with a repeated enhancer seemed higher than that of those with one copy of enhancer in 3 cases of thymic form lymphosarcoma. In 5 cases of thymic form lymphosarcoma and in 1 case of erythroleukemia, coexistent FeLVs with double and triple enhancers of different sizes were found. Of the enhancer elements, only the SV40 core binding site was found in all the enhancer direct repeats of these FeLVs. All the provirus clones with single and duplicated enhancer sequences from a single tumor showed mutations or deletions characteristic to that tumor, indicating that enhancer repeats may arise in individual animals after infection with a single virus clone. The present findings indicate that FeLV with enhancer repeats generated in the cat is associated with the induction of neoplastic diseases in natural conditions.

Three cases of proved peritoneal carcinomatosis were examined by magnetic resonance imaging (MRI). Air was used to distend the entire gastrointestinal tract via an antegrade method. The findings included seedings along the small intestine, transverse and sigmoid colon, stellate pattern in the mesentery, plaque-like and bulky tumor masses in the mesentery and greater omentum, and focal thickenings along the right subdiaphragmatic parietal peritoneum. Stenosis caused by tumor encasement at the duodenojejunal junction and ileocolic anastomosis were first detected by MRI and later confirmed by barium studies. Ascites was present in all cases. One case showed ascites located only along the left paracolic gutter. This report shows that MRI is also able to demonstrate peritoneal carcinomatosis by using air as a gastrointestinal contrast medium.

Free myocutaneous latissimus dorsi transplants are exceptionally used in cervicofacial surgery. The authors have performed an anatomical study of 23 non-embalmed subjects, using injections of neoprene latex and barium sulfate into the axillary artery and dye injections. Dissections, arteriographs and corrosion show that the lower scapular pedicle is constant, with an average length of 9.5 cm and a caliber that is sufficient for vasuclar microsurgery. Eight patients with large T4 cervicocephalic neoplasms were operated, including two with tongue tumors, one with a tumor of the oropharynx, two oromandibular lesions, two lesions of the maxillary sinus and a neuroblastoma involving the middle level of the facial structures. A free myocutaneous latissimus dorsi transplant was used. The transplant was revascularised by neck vessels using microsurgical techniques. Complete success was obtained in all eight patients. Good functional, cosmetic and morphological results were obtained as a rule. In cervicofacial surgery, the authors have thus chosen and used a free myocutaneous latissimus dorsi transplant in three topographic indications: for the oropharynx, to fill large cavities, especially the maxillary sinus, and to fill the middle level of the facial structures and of the base of the skull.

The triple endoscopies of direct laryngoscopy, bronchoscopy, and esophagoscopy, commonly known as panendoscopy, are frequent surgical procedures in otorhinolaryngology. Their purpose is to diagnose additional primary malignancies. The incidence of multiple synchronous primary malignancies has been reported between 3% and 13%. This unusually high rate is attributed to the process of field cancerization in which an anatomical region is exposed to a surface carcinogen and multifocal areas undergo irreversible change to multifocal malignancies. The majority of additional malignancies are diagnosed within 2 years of the index tumor's diagnosis, and are most consistently diagnosed within routine panendoscopy. Nevertheless, a significant percentage (40%) of additional primary malignancies present after this time and consequently, long-term follow-up is essential to the timely diagnosis of metachronous lesions. The predominant controversies surrounding panendoscopy involve the comparable diagnostic efficacies between endoscopic procedures and various radiologic studies. Although the operative complications reported for panendoscopy have been minimal, the expense is considerably greater than that of the respective radiologic alternatives. After a critical review of the literature, the use of endoscopy has been found to be superior to CXRs and barium swallows as the principal means of diagnosis of upper aerodigestive tract cancers. Specifically, bronchoscopy with bronchial washings should be obtained via passage of the bronchoscope through the endotracheal tube in order to decrease contamination. Positive washings are significant and demand further evaluation. Negative washings, on the other hand, yield little information.(ABSTRACT TRUNCATED AT 250 WORDS)

The diagnosis of gastric varices may be difficult due to their anatomic location and morphology. In this abstract we describe a case of gastric varices, of which a duplex Doppler sonography was useful in the diagnosis, that was initially suggested as submucosal tumor of the stomach by barium studies and endoscopy.

Gastric mucosal lesions in 13 patients with adult T-cell leukemia (ATL) were endoscopically studied at least at 2 occasions during chemotherapy for these patients. X-ray examinations by using barium meal showed deformities in 10 patients and abnormal mucosal pattern in 11 out of 13 patients with ATL. The endoscopic examinations revealed gastric ulcers in 5 patients, erosion in 8, diffuse bleeding in 2, tumorous mucosal folds in one, and submucosal tumor in one patient. In 9 out of 12 ATL patients, pathological study revealed that ATL cells had invaded the mucosal area of the stomach. The ulcers and erosions were improved by chemotherapy in 3 out of 5 and 5 out of 8 patients, respectively, whereas the erosion was not reduced in 2 and even aggravated in one patient. Interestingly, the gastric lesions formed by ATL cell invasion were improved by the administration of anticancer agents in 5 out of 9 patients. However, these lesions reappeared together with systemic lesions of ATL.

Prognostic factors in esophageal carcinoma treated with irradiation were examined. The prognosis of 111 patients without metastasis who had received more than 60 Gy was analyzed. Significant associations were found between survival rates and tumor length, stage, radioresponse of the primary tumor and the s.c. X-P classification based on barium contrast radiography; superficial type (tumor limited to the surface of the esophageal wall), tumorous type (solid mass without ulceration), Ul-A type (tumor with shallow ulceration with regular margin), Ul-B type (tumor with deep ulceration or irregular ulcer margin), and funneled type (tumor invading the esophageal wall in a scirrhous pattern). In multiple regression analysis, the X-P classification had the strongest correlation with survival and the survival rates of patients with the superficial type, the tumorous type and the s.c. Ul-A type were significantly higher than those of patients with the other tumor types (p < 0.001).
