Endoscopic treatment of a perforated duodenal diverticulum.

We describe a case of a perforated duodenal diverticulum, which was managed by a combined percutaneous and endoscopic approach. In combination with conservative treatment, this technique can be a challenging alternative to surgery.

Aortic pressure pain: clinical significance. Any relationship to the irritable bowel syndrome?

Pressure pain over the abdominal aorta is a clinical sign of undetermined significance. Ultrasonographic criteria were used to define and further evaluate this variety of epigastric tenderness. The incidence of aortic pressure pain, aortic characteristics, and gastrointestinal symptoms were scored in 250 consecutive patients. The incidence was approximately 7%. All the patients with aortic pressure pain had gastrointestinal symptoms, with a significantly higher mean symptom score. The occurrence of pressure pain was independent of any of the examined aortic characteristics, age, or body mass index. We further compared the incidence of aortic pressure pain between 25 patients with irritable bowel syndrome and 25 patients without apparent functional gastrointestinal disease. It was present in approximately 50% of the patients with irritable bowel syndrome. We found pressure pain over the abdominal aorta to be associated with significant gastrointestinal discomfort. A causal relationship is possible but not proven. Aortic pressure pain can be provoked in a significant subgroup of patients with the irritable bowel syndrome.

Infectious gastroenteritis: are they all the same?

Campylobacter jejuni and Salmonella spp are the most frequently cultured micro-organisms in infectious gastroenteritis among patients hospitalized at the departments of gastroenterology and geriatrics. As a whole, the hospitalized patient population with Campylobacter gastroenteritis is a younger one, compared to the Salmonella-infected group. Both pathogens can be associated with a biochemical pancreatitis, which is usually without clinical importance. However, serious complications can occur, with a predominance of visceritis for C. jejuni, and renal function impairment for Salmonella spp. Finally, an asymptomatic carrier state is well known in the Salmonella infection spectrum, whereas C. jejuni might cause a recurrent disease in some patients.

A case of Peutz-Jeghers syndrome with nasal polyposis, extreme iron deficiency anemia, and hamartoma-adenoma transformation: management by combined surgical and endoscopic approach.

We report a rare variant of Peutz-Jeghers syndrome identified by the presence of nasal polyposis and extreme anemia. Multiple hamartomatous polyps were found throughout the upper and lower gastrointestinal tract. We conducted a combined surgical-endoscopic approach to prevent the development of a short-bowel syndrome. The polyps removed by snare and surgical polypectomy showed features typical of harmartomas. Three colonic polyps and two nasal polyps showed histological evidence of adenomatous change. This adenomatous change seems to fit into the pathogenic sequence of hamartoma-adenoma.

Combined percutaneous balloon dilation and extracorporeal shock wave lithotripsy for treatment of biliary stricture and common bile duct stones.

We report a case of cholangitis, liver abscess, and common bile duct stones in a patient with a benign stricture at a choledochojejunal anastomosis, 3 yr after a complicated duodenohemipancreatectomy. Because surgical reintervention seemed inappropriate, a percutaneous transhepatic balloon dilation was performed after temporary internal-external biliary drainage. Extracorporeal shockwave lithotripsy (ESWL) was successfully applied to fragment all common bile duct stones, with subsequent spontaneous evacuation of all stone fragments through the dilated bilioenteric anastomosis. Only one similar case report has been published before (1), though with a different sequence of therapeutic modalities. Moreover, according to our literature review, this is the first report of ESWL of common bile duct stones by means of the Dornier Compact Lithotriptor (Dornier, Germany) with electromagnetic shockwave source.

Endoscopic drainage of pancreatic pseudocysts.

Endoscopic drainage is a recent method in the management of pancreatic pseudocysts. It has been developed as an alternative to surgical treatment in high risk patients. Our experience with this technique is illustrated by a well documented case report which is followed by a brief review of the literature.

Endoscopic sclerotherapy: the value of balloon tamponade and the importance of disinfection.

Endoscopic sclerotherapy in active variceal bleeding stopped bleeding in 48 out of 67 patients (72%). Survival of the acute bleeding episode was related to liver function: 6% mortality in Child A patients vs. 48% mortality in Child C. Comparing two treatment modalities: 24 h Linton balloon tamponade followed by sclerotherapy vs. sclerotherapy alone, our results in comparable groups slightly, although not significantly, favor tamponade-sclerotherapy treatment: 75% survival vs. 71%. As this treatment modality is more convenient and helps to avoid dangerous aspiration pneumonia, we advocate balloon tamponade prior to sclerotherapy in acute variceal bleeding. In maintenance treatment 65 patients were treated until eradication of varices. The rebleeding risk was 0.034% per patient per month, with 64% of the rebleeding within the 2 first months before complete eradication of the varices. The long-term survival depends largely on liver function: one year survival of 88% in Child A vs. 30% in Child C. Using Aethoxysklerol 1% in intravariceal injection, no stricture occurred. Using a sterile injection needle and a glutaraldehyde-disinfected endoscope, no infectious complications directly related to the procedure occurred, and all hemocultures remained negative.
