The problems arising from the discovery of a colorectal tumor during an infectious endocarditis caused by Streptococci D have rarely been mentioned in the surgical literature. The frequency of association of an asymptomatic colorectal tumor and of a Streptococcus bovi endocarditis is now undisputed. This notion implies the systematic search for an intestinal lesion (adenoma or carcinoma) in case of endocarditis or septicemia without involvement of the valves, caused by a streptococcus of group D. The authors report about 3 cases of enterococcal (1 case) and S. bovis (2 cases) infectious endocarditis revealing a colic adenocarcinoma (2 cases) and a villous adenoma (1 case), all being perfectly latent. The specific therapeutic problems arising from this association are outlined, including the antibiotic therapy, the role of the anticoagulant treatment and the priority given to valve surgery in case of hemodynamic instability.

Endotoxemia remains the leading cause of death in horses, being intimately involved in the pathogenesis of gastrointestinal disorders that cause colic and neonatal foal septicemia. Endotoxins, normally present within the bowel, gain access to the blood across damaged intestinal mucosa, or endotoxemia occurs when gram negative organisms proliferate in tissues. Endotoxins are removed from the circulation by the mononuclear phagocyte system, and the response of mononuclear phagocytes to these lipopolysaccharides (LPS) play an important role in determining the severity of clinical disease. Macrophages become highly activated for enhanced secretory, phagocytic and cidal functions by LPS. Macrophage-derived cytokines are responsible for many of the pathophysiologic consequences of endotoxemia. The arachidonic acid metabolites, prostacyclin and thromboxane A2 likely mediate early hemodynamic dysfunction and the leukotrienes may potentiate tissue ischemia during endotoxemia. Interleukin 1 (IL-1) induces fever and is responsible for the inflammatory cascade, which constitutes the acute phase response. Tumor necrosis factor (TNF), an important proximal mediator of the effects of LPS, acts to initiate events and formation of other molecules that affect shock and tissue injury. Systemic administration of TNF produces most of the physiologic derangements that are associated with endotoxemia and antibodies that are directed against TNF significantly reduce LPS-induced mortality in experimental animals. In response to endotoxins, mononuclear phagocytes express thromboplastin-like procoagulant activity (PCA), which initiates microvascular thrombosis. Both IL-1 and TNF induce PCA expression, creating a positive feedback loop for LPS-induced coagulopathy. A macrophage-derived platelet activating factor contributes to coagulation dysfunction and further stimulates arachidonic acid metabolism. The ultimate consequences of endotoxemia are multiple system organ failure and death. The numerous feedback loops and intertwining cascades of mediators during endotoxemia defy simplistic methods of treatment. The optimal therapy likely involves methods to alter the generation of inflammatory mediators by mononuclear phagocytes.

Campylobacter is considered to be an opportunistic agent. The authors relate an unusual case with Campylobacter fetus ssp fetus (CF) septicemia and colic abscess. Human Campylobacteriosis is presumed to be a food-born disease related to contaminated animal products such as milk or meat. In some cases CF may be transmitted by drinking water or by fecal soiling via the hands. Conventional treatment uses macrolides with decrease the duration of diarrhea and reduce the fecal excretion of CF. Macrolides are ineffective in CF septicemias. In such cases aminoglycosides seem to be the drug of choice.

Five cases pyloric obstruction, revelated at the birth-period were summarized from 1964 to 1987; 1 pyloro-duodenal atresia, two cases of total pyloric obstruction by diaphragm, two cases of pyloric obstruction associated with several ileal and/or-colic atresia in the same family, and suspected at the antenatal echographic study. The treatment was either pyloro-duodenal anastomosis (1 case) or diaphragmatic resection with pyloroplasty (4 cases). In immediate results are obtained one immediate death, at the third day, and 4 initial good results; but two deaths came in a further period at 3 months and 8 months (the same family) with sepsis after ileus. A syndrome of immuno-deficiency was demonstrated in this two familial cases.

Nephro-intestinal fistulas involve the GI tract and the kidney or pyelocalyceal system. The main causes may be urologic or digestive, the site diverse. Reno-colic fistulas, although rare, are more frequently observed. We describe a case of left reno-colic fistula secondary to lithiasic pyonephrosis that presented as sepsis. Diagnosis was confirmed by retrograde pyelography. Treatment was by surgery (left nephrectomy, closure of the fistula, and colonorhaphy).

The historical, clinical, laboratory, surgical and necropsy findings in 54 cases of gastric rupture in horses are described. Eleven per cent of the deaths of horses undergoing exploratory coeliotomy for colic during the period of the study were a result of gastric rupture. Comparison with all horses which had exploratory coeliotomies for colic over an eight year period did not show that horses with gastric rupture were different from these reference horses regarding age, breed or season. There were fewer stallions than expected in the gastric rupture group. Horses with histories of both acute and chronic (more than 36 h) colic were susceptible to gastric rupture. Primary and idiopathic causes of gastric dilation and rupture accounted for about one-third of the horses. All but one of these cases resulting from secondary causes fell into three aetiologically-related groups: obstructive, peritoneal and enteric, with approximately equal numbers of horses in each group. Most of the ruptures occurred along the greater curvature of the stomach. At least six horses ruptured their stomachs postoperatively in the presence of an indwelling nasogastric tube. The presence or absence of gastric reflux following nasogastric intubation was not a reliable indicator, on its own, of gastric dilation. Horses that later died from gastric rupture had markedly elevated heart rate, hypochloraemia, peritoneal exudative effusion (particularly with evidence of sepsis), pre- and/or postoperative gastric reflux and small or large intestinal disease. However, no distinctive feature of these horses was shown to place them at risk of gastric rupture.

Percutaneous nephrolithotomy - PCNL - was made possible by technological progress, with the introduction of nephroscopes, lithotomy forceps, and mechanical, ultrasonic or electrohydraulic lithotriptors. The procedure includes four stages. First needle puncture of the inferior or middle calyx. Secondly, dilatation of the pathway and creation of a tunnel. Thirdly, investigation of the collecting system. And, finally, extraction of the stone. The results of 302 published cases show a success rate of 87 per cent, a complete failure rate of 13 per cent, and residual stones in 10 per cent of cases. The complication rate is 7 per cent, with hemorrhage and sepsis in roughly equal proportions. A few other complications are occasionally reported, such as colic wounds, perirenal collections, traumas of the ureteropelvic junction, pneumothorax, or a stone left in the lumbar wall. There was one case of death. The hospitalization period is the same as for lombotomy, but the return to work is more rapid. The best indications are pelvic and inferior calyceal stones (with a success rate of over 80 per cent). Despite their enthusiasm for this procedure, the authors feel that is still remains to be seen or whether it will in turn be superseded by ultrasound lithotripsy.

The authors report on two cases of uretero-colic fistulization in the post-operative period, following surgery for infectious complications involving sigmoidal diverticulitis. In the aftermath of surgery for sigmoidal diverticula, the appearance of very liquid stools at the exact moment when the infectious and semi-occlusive picture seems to resolve, the occurrence of a uro-steraceous fistula should make one suspect a uretero-colic fistula. Air pyelography and the retrograde opacification of the ureter following a radio-opaque enema are diagnostic. The IVU does not help to establish a firm diagnosis but is useful for showing the state of the adjacent kidney and above all the state of the contralateral kidney. In regard to the sepsis which accompanies these complications (there is nearly always a pericolic abscess at the site of the utero-colic fistula) all attempts at repair are futile. Only nephrectomy may be sometimes appropriate. At the same time, nothing except treatment of the infectious focus (colic or pericolic) will safeguard the patient from the risk of further infection which might end in death. The risk of damage to the ureter which sigmoidal diverticular surgery carries, necessitates the following precautions: a pre-operative IVU, a painstaking dissecting-out and well wide of the neighbouring ureter, the systematic injections of dye to colour the urine at the time of operation in order to avoid ureteric injury and of course to ensure the repair of any injury as soon as it happens. It is only possible to save the adjacent kidney and protect the normal urinary outlet if the ureteric lesion is properly identified at operation.

Surgery does not cure Crohn's disease, but only its complications, as the recurrence rate that requires a new intervention is 6% per year. The resections performed by the surgeon should be as limited as possible, in order to avoid the consequent malabsorption. The identification of two forms of Crohn's disease, with different aggressiveness, has found that the stricturoplastic is an encouraging way of treatment for those forms with a prevalent stenotic component. A lot of studies have evaluated the relationships between recurrences and resections on margins microscopically free or affected by the disease. The aim of this study was a retrospective verification of the influence of any possible microscopical residue of the disease on the recurrence rate, evaluating whether the two different forms of aggressiveness of the disease (presence of stenosis or fistula) can influence the rate and precocity of the recurrence onset. In 37 patients operated for the first time of ileal or ileocolic resection, the overall recurrence rate was 18.9%; neither the presence of microscopically affected margins nor the presence of fistulas or stenosis has showed to have an influence on the onset of the recurrences. The only data that emerged is a greater precocity of the onset of recurrence in those patients whose disease was characterised by the presence of enteric fistulas. The forms in which fistulas and perforations were evident showed a recurrence rate not significantly higher than that of forms with stenosis only, but the period of time free from the disease was notably longer for the latter. In the end, patients in which typical granulomas were present showed a recurrence rate of just 9%, compared to 23% of patients in which granulomas were absent. MATERIALS AND METHODS. From 1980 through 1992, 61 patients affected by Crohn's disease were operated. There were 39 men and 22 women (mean age: 40.4 years). The mean length of the follow-up was 55.5 months. It was the first operation for 43 patients, while 9 had already undergone surgery in other hospitals; 9 patients showed anorectal complications. The operations performed on the patients for the first time have been ileal resection in the following localizations: duodenum-jejunum 4, jejunum and ileal 34, colic 5; the recurrences treated have been ileal-jejunum in 7 cases and colic in 2. In 2 cases of recurrence a stricturoplastic has been performed. RESULTS. The operative mortality was of 3 patients: 2 due to sepsis for anastomotic dehiscence and 1 to systemic mycosis. Four postoperative fistulas were observed. Recurrence of the disease occurred in 13 patients (26.5%), specifically in 21.4% of the patients operated for the first time and in 57.1% of those that were operated for recurrences. DISCUSSION AND CONCLUSIONS. In the treatment of Crohn's disease, it is important to identify any possible group with high risk of recurrence in order to undertake an appropriate medical prophylaxis. The results concerning the presence of microscopical disease on the resection margins are today still controversial. Some groups of authors prefer wide resection margins, some others are in favour of restricted resections. Our considerations let us assert that in those patients in which the resections have been performed on margins with microscopic presence of the disease, the interval before the recurrence occurs is not significantly shorter than that of patients with free margins. But the patients suffering from Crohn's disease with fistulae, probably need medical post-operative therapy to delay recurrences onset.

A total of 25 patients at least 75 years old underwent continent urinary diversion via a modified Indiana Pouch during a 68-month period, 21 of these with simultaneous radical cystectomy or anterior exenteration. The preoperative medical conditions as well as the early and late operative morbidity and mortality are reviewed with a mean follow up of 27 months. Average age of patients was 78.5 years, and the mean age of survivors is 81 years. There were two early mortalities attributed to ileal gangrene with secondary sepsis and aspiration pneumonia. Postoperative complications (superficial wound infection, middle colic vein bleed, right ureteral leak, ileus) occurred in five patients, two of whom required re-operation. Mean hospital stay was 12.4 days and ranged from 9-20. There were only six late complications [ureteral stricture (3), small bowel obstruction (1), incontinence (1)] necessitating re-hospitalization and surgical intervention. Late infectious complications included recurrent urinary tract infections (3), pyelonephritis (2), and C. Difficile enterocolitis (2) all managed medically. In addition, 10 other patients have died, 9 from metastatic disease and 1 from intercurrent medical problems. Of the 13 remaining patients, 11 are disease free and all are continent with a mean follow-up time of 33 months. We conclude that continent urinary diversion via a modified Indiana pouch with radical cystectomy or anterior exenteration can be performed with minimal morbidity or mortality, even in an elderly population.
