[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.

[A case of acute sensory and autonomic neuropathy with regression].

The authors report the case of a 24 year old man with no previous disease who presented with a severe autonomic neuropathy. This included major gastrointestinal dysfunction characterised by decreased peristalsis without distension and paralysis of the gall bladder, and orthostatic hypotension with a normal cardiac tachycardia reflex. There was an associated sensory neuropathy affecting heat sensitivity without motor dysfunction and an increased CSF protein content. The proprioceptive nerve fibre conduction was decreased but another nerve conduction was normal initially. The mesenteric plexuses examined during sigmoidectomy performed for peritonitis due to multiple bowel perforations caused by fecoliths, showed no significant changes. Peripheral nerve biopsy revealed massive rarefaction of myelinated fibres which were of small diameter, and of the unmyelinated fibres, mainly due to axonal degeneration. Only two similar cases with incomplete recovery were found in the literature. In our case, a complete recovery was observed. The cause of the condition is unknown.

[Normal pregnancy after a Budd-Chiari syndrome treated by shunting: apropos of a case, review of the literature].

A patient who had a meso-atrial by-pass for a Budd-Chiari syndrome a year before conception carried her pregnancy to term. The authors have reviewed the literature. When they had studied the literature the authors took into account cirrhoses of the liver and portal hypertension in association with pregnancy. They concluded that a patient who had had a Budd-Chiari syndrome, particularly when she had also had a porto-caval shunt, was not in principle unable to have a pregnancy.

[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.

Hemodynamic effects of portal triad clamping in humans.

The hemodynamic effects of portal triad clamping (PTC) were studied in 48 adult patients scheduled for elective liver resection. Prior to hepatic resection the effects of a short period of PTC (3-5 min) were evaluated in all 48 patients: mean arterial pressure increased 21%, whereas pulmonary capillary wedge pressure and cardiac index decreased 10 and 17%, respectively. Systemic vascular resistance increased 48%. In 34 patients a liver resection was performed during PTC and hemodynamic measurements were repeated throughout the duration of liver ischemia, which ranged from 14 to 68 min. Hemodynamic changes occurred in the first 3 min and persisted thereafter. After releasing the clamp, hemodynamic parameters returned to initial values in 3 min. These results confirm that PTC does not induce the cardiovascular collapse in humans that it does in common laboratory animals and demonstrate that humans tolerate PTC for periods up to 1 hr.

Resection and colo-anal anastomosis with colonic reservoir for rectal carcinoma.

Sphincter-saving operations are now generally accepted for the treatment of mid-rectal cancers. Many techniques have been described: low colorectal anastomosis, pull-through procedures, and colo-anal anastomosis. The functional results following these operations are impaired by loss of the reservoir function of the rectum. In order to improve these results, a modification of Parks' colo-anal anastomosis is proposed. A J-shaped colic reservoir is constructed and its end is anastomosed to the anal canal. We have operated upon 31 patients using this technique. Mortality was 3.3 per cent. Functional results were evaluated in 24 patients having a follow-up of more than 3 months. All were continent; mean number of bowel movements was 1.1 per day. Defaecation was spontaneous in 75 per cent of cases; in the remaining 25 per cent, evacuation of the reservoir was elicited by a small enema each two days. This technique, creating a neo-rectum, can achieve an important place among the sphincter-saving operations.

[Anemia in the elderly subject secondary to jejunal vascular malformation. Apropos of 2 cases].

Two cases of normocytic regenerative anemia in two patients aged 84 and 86 respectively were related to gastrointestinal bleeding. Abdominal angiography was negative in both cases. Only laparotomy provided a diagnosis of jejunal vascular malformation with the aid of peroperative endoscopy. Angiodysplasia was diagnosed in one case and capillary hemangioma in the other. In these very old people with very somber prognosis, anemia was corrected by surgery without recurrence after 8 and 10 months respectively. Gastrointestinal malformations are found in about 20 p. 100 of unexplained digestive hemorrhages. In most cases they are localized in the right large bowel, especially in old patients. Jejunal localizations are 7 to 8 times less frequent and have been described in younger patients. Up to now, selective abdominal angiography has been the main diagnostic procedure. We must insist on the value of peroperative endoscopy when angiography is negative.

[Results of choledoco-duodenostomy for common bile duct lithiasis].

One hundred and sixty-seven choledoco-duodenostomies for lithiasis of the common bile duct (CBD) were performed. The mean age of the patients was 74 +/- 1 years. Sixty p. 100 of the patients presented with at least one operative risk factor, usually related to their general condition. An anastomosis of at least 20 mm in diameter was possible as the diameter of the CBC was always larger than 10 mm. Immediate postoperative complications (within one month) were observed in 29 cases (17 p. 100). In 14 cases (8 p. 100), these complications were directly related to the operative procedure and, in 15 cases (9 p. 100), bronchopulmonary or cardiovascular complications occurred. Operative mortality was 4 p. 100 (7 cases); in 2 cases, death was directly related to the operative procedure, and in 5 cases, death was not directly due to surgery. Operative complications were significantly higher in the case of emergency procedures, impaction of the CBD by multiple stones, and associated acute cholecystitis. One hundred and thirty-four of the 160 survivors (84 p. 100) have been followed for a mean duration of 5 years (63 +/- 7 months); 115 (86 p. 100) have remained asymptomatic. Eleven patients had non specific findings; 8 (6 p. 100) had cholangitis, half of them having suffered from only one episode. The first (or only) episode occurred during the first postoperative year in 7 out of 8 patients. No cholangitis developed after the second postoperative year in patients still asymptomatic. No anastomotic stenosis was found in any of these cases. One case of stump syndrome was observed. These results suggest that choledocoduodenostomy is a reliable procedure for treatment of choledocolithiasis and related late complications are rare.
