[Quantified symptomatology of acute appendicitis in adults. The signs and their value].

Using a data base of 7,000 acute abdominal pains, we here described the assessed clinical manifestations of the main diseases responsible for right lower quadrant pain. However, percentages of sensibilities have been replaced by adverbs or adjectives, applying a scale of equivalence. The possible modifications of the positive predictive values have been also replaced by verbs or typical expressions. We first described the acute appendicitis syndrome (which covered congestive endoappendicitis and suppurated appendicitis) with the clinical shades or the gathered and gangrenous forms or even of the diffuse peritonitis. Features of the acute appendicitis contrast with those of the so called "non specified abdominal pains" (a new entity), and those of the subacute or chronic appendicitis. We found a good correlation between clinical and pathological findings. One of the difficulties has been to determine if a subgroup of subacute appendicitis should be or not included into the acute appendicitis.

[Questionable appendectomies].

Each year in France, 75,000 appendectomies are carried out for normal or fibrous appendix and another 75,000 for a mere inflammation of the mucosa of submucosa. To decrease the incidence--four times higher than in other countries--it is suggested to keep under observation the patient with RIQ tenderness if they have neither rebound nor guarding, a temperature below or equal to 38 degrees C and a white blood cell count lower than 10,000/mm3. By following these guidelines, there is no risk to miss perforated or suppurated appendicitis.

[Antibiotic prophylaxis in abdominal surgery. Prospective randomized study organized by the French Surgical Research Association].

The effectiveness of cefazolin or cefotaxime as antibiotic therapy was compared with that of ceftriaxone in a multicentre prospective randomized trial involving 1,254 consecutive patients operated upon for abdominal diseases. Patients about to undergo surgery of the colon or who had localized or generalized peritonitis at the time of operation were excluded from the study. The patients entered were divided into 4 strata according to the degree of operative contamination and to risk factors. In each stratum, the patients were allocated at random to one or the other of 2 treatment groups. Group 1 patients received cefazolin or cefotaxime in 3 doses of 1 g administered 8-hourly, the first dose being injected during induction of general anaesthesia. Group 2 patients received one single 1 g dose of ceftriaxone injected during induction of anaesthesia. There was no significant difference between the two groups in the wound infection rate and in the frequency of post-operative intra-abdominal abscesses. Although the percentage of post-operative pulmonary and urinary tract infections was lower in the ceftriaxone group than in the cefazolin/cefotaxime group, no significant difference was observed between the two groups in the number of patients who required curative antibiotic therapy. This study shows that one single dose of ceftriaxone is as effective as three doses of cefazolin or cefotaxime in preventing would infections and post-operative intra-abdominal abscesses, and that it is more effective in preventing extra-abdominal infections complicating surgery.

Ascites revealing peritoneal and hepatic extramedullary hematopoiesis with peliosis in agnogenic myeloid metaplasia: case report and review of the literature.

A 61-year-old man presented with ascites in the course of agnogenic myeloid metaplasia (AMM). Ascitic fluid was exudative and contained mature and immature leukocytes, erythroid cells, and megakaryocytes as observed on a bone marrow smear. Peritoneal biopsy showed myeloid metaplasia, and liver biopsy revealed intrasinusoidal myeloid metaplasia and peliosis. Ascites cleared after abdominal radiotherapy but treatment resulted in transient aplasia. Subsequently, portal hypertension was demonstrated by hepatic transjugular catheterization. Complications of splenomegaly led to splenectomy and splenorenal shunt followed by fatal acute hepatitis and septic shock. A review of the literature and an analysis of mechanisms of ascites occurring in AMM, especially peritoneal implants of myeloid tissue and occurrence of peliosis in myeloproliferative disorders, are presented.

[How to express the percentage of words expressing the frequency (or sensitivity) of symptoms in a disease?].

A prospective multicenter study concerning 30 vocabulary terms was undertaken to determine if: 1) these terms could be equated with specific percentages; 2) observer assessment varied with time; 3) teachers and students used the same words with the same meaning; 4) certain words were more discriminant than others, and 5) terms corresponding to numbers were the same in French as in English. Three hundred and thirty medical professionals, coming from general and digestive units of 45 University, regional, or private institutions, were asked to answer three types of questionnaires pertaining to the same 30 words, but in a different order. One to 3 months later, 170 of them were asked to fill out the same questionnaire with the same words but in a different order. Sixteen percent were University professors, 15 percent were hospital or private surgeons, 19 percent were senior residents, 29 percent were interns or junior residents and 21 percent were medical students.(ABSTRACT TRUNCATED AT 250 WORDS)

[Distal splenorenal anastomosis in the treatment of digestive hemorrhage in portal hypertension].

One hundred and ten distal splenorenal anastomoses (DSRA) were performed between 1976 and 1988 for gastrointestinal haemorrhages secondary to portal hypertension. Thirty five patients underwent DSRA (Warren's operation) followed by a mesenteric disconnection procedure. Eleven patients (10%) died (nine Child B and two Child A), including two after an emergency shunt. The mortality was influenced by age (p less than 0.01) and by the number of previous episodes of ictero-ascitic decompensation (p less than 0.02). A single anastomotic thrombosis was observed; the high flow rate of the anastomoses (mean: 1200 +/- 650 ml/min) explains the high patency rate (more than 90%). Eleven patients developed partial or total thrombosis of the portal trunk less than 6 weeks after the operation. The quality of hepatic perfusion was not significantly influenced by the mesenterico-splenic disconnection and this was omitted in 75 patients. The mesenterico-splenic collateral venous circulation was more developed in the absence of disconnection (p less than 0.05). The long-term actuarial survival was 83% at one year, 53% at five years, 47% at eight years and 28% at ten years. Survival was not influenced by the disconnection. Warren's operation is more difficult to perform than a porto-caval or mesenterico-caval shunt. DSRA appears to have three advantages: 1) a high flow rate as it is arterialised by the splenic artery, 2) hepatopetal portal perfusion maintained for several days, weeks or months, possibly reducing the risk of encephalopathy, 3) the absence of dissection of the hepatic pedicle preserves the possibilities of liver transplantation.

Total versus subtotal gastrectomy for adenocarcinoma of the gastric antrum. A French prospective controlled study.

In a multicentric trial the postoperative mortality and the 5-year survival of elective total gastrectomy (TG) was compared with subtotal gastrectomy (SG) for adenocarcinoma of the antrum operated on with intent of cure. Two hundred and one patients were included in the study; 32 were excluded after pathologic examination (linitis plastica, superficial cancer, lymphoma). One hundred sixty-nine patients remained for analysis, with 93 undergoing TG and 76 undergoing SG. Elective TG did not increase postoperative mortality (1.3%) compared with SG (3.2%). There was no difference in the 5-year survival rate (48%). Analysis of survival showed no difference in the two techniques when related to nodal involvement and serosal extension. It is concluded that both TG and SG can be performed safely in patients with adenocarcinoma of the antrum; however TG did not increase the survival rate.

[Acute duodenal ulcers complicating Listeria meningitis (author's transl)].

The authors report 3 cases of acute complicated duodenal ulcers occurring during the course of Listeria meningitis. These three adults (2 females and 1 male) suffered from localised neurological involvement and, in 2 cases neurovegatative disorders an altered level of consciousness. The ulcers were situated in the duodenal cap, and in each case there were at least 2 large excavated ulcers. These ulcers were the site of late complications on the 13th and 15th days after the onset of neurological disease. In two cases the major symptom was haemorrhage, whilst in the third it subsided leaving a syndrome of peritonitis due to perforation. Treatment in all three cases consisted of vagotomy with pyloroplasty (the ulcers being excised or sutured). All the patients recovered from their digestive complications without relapse despite the persistence 6 and 10 months later of the same neurological problems in two of them. All these facts would be in favour of a neurogenic aetiopathogenesis, via the vagal nerve. Thus acute late duodenal ulcers in patients with neurological disease from a separate enity within the context of stress lesions.
