[Current role of total esopharyngo-laryngectomy in cervico-facial cancerology. Apropos of 11 cases].

Eleven patients underwent total esophagopharyngolaryngectomy for cancer, with colic or gastric digestive reconstructive surgery. Postoperative course is analyzed, contraindications and indications outlined and other methods of pharyngeal reconstruction discussed. An extension to the technique is proposed to include tumors requiring a circular pharyngolaryngectomy. Improvement in the very poor prognosis of these tumors can only be envisaged by the use of enlarged surgery combined with chemotherapy and radiotherapy.

[Surgical treatment of Oddi's sphincter tumors. Apropos of 56 cases].

The records of 56 patients operated upon for ampullary tumors were reviewed in order to determine the best way to diagnose and treat these tumors. Thirty six males and 20 females, 30 to 89 years old, were operated upon between October 1970 and October 1985. Eighty six p. 100 had jaundice and 21 p. 100, anemia. In recent years, ultrasonography, duodenoscopy and ERCP appeared to be the most useful tests for diagnosis. Mean size of the tumors was 2.3 cm (0.5 to 5 cm). Five tumors were benign (8.9 p. 100) and 51 were malignant. According to the classification of Martin, 5 were grade I: 10, grade II: 18, grade III: and 18, grade IV. The correct histologic diagnosis was obtained on biopsy specimens taken during endoscopy in 7 of 12 patients. Nine patients underwent palliative choledocoduodenostomies: only one is alive at 3 years; 47 underwent resection of the tumor: 3 local excisions associated with sphincterotomy for small benign tumors, 6 ampullectomies (followed in 3 by a Whipple procedure for recurrence) and 41 Whipple procedures. After pancreatic resection, 3 patients died during hospital stay and 12 had reversible complications; overall 5 year survival was 41 p. 100. It was 75 p. 100 in grade I, 50 p. 100 in grade II, 40 p. 100 in grade III and 10 p. 100 in grade IV. Patients who received an ampullectomy were alive with a follow up of 1, 2, and 3 years. All patients operated upon for a benign tumor were alive except one who died of cardiac failure.(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatic resection for colorectal liver metastases. Influence on survival of preoperative factors and surgery for recurrences in 80 patients.

This report analyses an experience with 80 liver resections for metastatic colorectal carcinoma. Primary colorectal cancers had all been resected. Liver metastases were solitary in 44 patients, multiple in 36 patients, unilobar in 76 patients, and bilobar in 4 patients. Tumor size was less than 5 cm in 33 patients, 5-10 cm in 30 patients, and larger than 10 cm in 17 patients. There were 43 synchronous and 37 metachronous liver metastases with a delay of 2-70 months. The surgical procedures included more major liver resections (55 patients) than wedge resections (25 patients). Portal triad occlusion was used in most cases, and complete vascular exclusion of the liver was performed for resection of the larger tumors. In-hospital mortality rate was 5%. Three- and 5-year survival rates were 40.5% and 24.9%, respectively. None of the analysed criteria: size and number of liver metastases, delay after diagnosis of the primary cancer, Duke's stage, could differentiate long survivors from patients who did not benefit much from liver surgery due to early recurrence. Recurrences were observed in 51 patients during the study, two thirds occurring during the first year after liver surgery. Eight patients had resection of "secondary" metastases after a first liver resection: two patients for extrahepatic recurrences and six patients for liver recurrences. Encouraging results raise the question of how far agressive surgery for liver metastases should go.

[Colo-anal anastomosis with reservoir in the treatment of rectal cancer].

Preservation of the anal sphincter system is now often considered in the treatment of adenocarcinomas of the mid-rectum (inferior limit between 11 and 6 cm of the anal margin). Direct anastomosis of the rectum to the anus or the last two centimeters of the rectum after resection of the rectal pouch is a source of discomfort. The construction of a colon pouch, placed directly above the anus, has been devised in order to improve these results. In the last three years, a J-shaped colon pouch, measuring 8 centimeters X 2, was constructed in 76 patients and anastomosed in its portion to the anal canal, after complete rectal resection. The functional results of this procedure, with uneventful post-operative course, were evaluated in 66 patients with a mean follow-up of 17 months. Continence was satisfactory in 96% of patients, with an average number of stools of 1.4 in 24 hours. Thirty one per cent of the patients require a small enema or a suppository to induce defecation.

An original technique for histological study of the human temporal bone.

An original technique for histological study of the human temporal bone is presented. It allows faster and better results than previous methods. It becomes obvious that the systematic study of the temporal bone may give important data in the field of pathology, foeto-pathology and forensic medicine.

[Adenocarcinoma of the cervical esophagus. Association with a gastric heterotopia].

Adenocarcinoma of the cervical esophagus is a very rare lesion. A case is reported of this tumor developing in the presence of gastric heterotopia of mucosa of cervical esophagus. The integrity of the remaining esophageal mucosa eliminates the possibility of cancer developing on an endobrachyesophagus. The association in a young patient of an adenocarcinoma of cervical esophagus and gastric heterotopia is suggestive of a pathologic relation.

[Anatomo-pathologic study of the temporal bone in our 4 cases of sudden infant death].

A new etiopathogenic theory is proposed by the authors about four cases of sudden infant death syndrome. A new histological method on the temporal bone was used applied in these four cases. Inner ear and meningeal injuries were observed. From this observation they proposed the possibilities of brain-stem injury through neurogenic or meningeal pathways. These injuries could be responsible for apnea syndrome and loss of alertness.
