Blind pouch syndrome: a case report.

The blind pouch syndrome is associated with a spectrum of diseases affecting the gastrointestinal tract that includes: malabsorption, ulceration, bleeding, and perforation. The clinical signs and symptoms of anemia, weight loss, abdominal pain, vomiting, and intermittent intestinal obstruction can be found. Occasionally, constipation or more often diarrhea is an important manifestation. A case report of this entity with related radiological and pathological findings secondary to a side-to-side anastomosis is presented and discussed.

In vivo demonstration of microvascular pathology by intravital microscopy in experimental chronic graft-versus-host disease: analogy with scleroderma.

Experimental models of chronic graft-versus-host disease have been advocated for studying the pathogenesis of scleroderma. However, microvascular abnormalities have not been documented in these models, whereas in man, cutaneous microvascular pathology (demonstrable by intravital microscopy) is a common feature of scleroderma. In our study scleroderma-like skin disease was evoked by allogeneic bone marrow transplantation in rats. Intravital microscopy of the skin of these animals showed strongly dilated capillaries, resembling the dilated loops in patients. This finding demonstrates that chronic graft-versus-host (scleroderma-like) disease may be pertinent to study the pathogenesis of microvascular injury in scleroderma.

[Stenosis endoscope. A new instrument for the diagnosis and therapy of stenoses in the gastrointestinal tract].

A new type of endoscope combines the advantages of the narrow-calibre paediatric endoscopes and the stable-shaft regular endoscopes. This is achieved by reduction of the distal diameter from 13 mm to 9,5 mm with a conical transition between both parts. These characteristics make the instrument particularly suitable for the diagnosis of gastrointestinal stenoses (stenosis endoscope). At the same time the stenosis endoscope dilates as well as a metal olive or a rubber bougie. Thus dilatation of gastrointestinal stenoses is now possible beyond the reach of instruments used as bougie or for dilatation until now. The stenosis endoscope opens new possibilities of therapeutic endoscopy.

The fate of loop ureterostomy and severe contracted bladder.

Bladder contracture following cutaneous loop ureterostomy is a known but sometimes neglected serious complication. Recently we treated a boy successfully by effecting an increase in bladder capacity by long-term hydraulic dilatation prior to performing colonic augmentation. The severity of the contracture seems to be the worst ever published in the literature.

Transluminal balloon dilation of ureteral stricture in a child. A case report.

A 12-year-old girl complained of left flank pain 4 months after the onset of symptoms of polyarthritis nodosa with hypertension, multiple neuritis and impaired renal function. Intravenous pyelography (IVP) revealed no stone. Several months later the flank pain recurred, and IVP now showed a calcified stone midway in the left ureter. Ureterolithotomy was performed, and a 3 cm long stone embedded in the mucosa was removed. Two months postoperatively IVP showed severe ureteric obstruction due to stenosis at the level of the incision. Dilation of the stricture was accomplished with a 4 mm balloon, and further dilation 2 weeks later with a 6 mm balloon. A third dilation was performed with a 4 mm balloon. At examination 3 months later the girl was free from symptoms and IVP with forced diuresis was normal, as were the findings after 6 more months. Transluminal balloon dilation of postoperative ureteral strictures in children should be considered as an alternative to surgery.

[Endoscopic dilatation of benign colon and rectum stenosis].

AIM: To determine the usefulness of endoscopic dilatation in dealing with benign stenosis of the anus, rectum and colon. PATIENTS AND METHODS USED: Thirty six (36) patients with stenosis, anus (8), rectum (22) and colon (6) were given endoscopic treatment using hydroneumatic balloons, electro incision (radiated cuts) or a combination of both. Rigid equipment (metal) was used for distal stenosis. Age ranged between 30 and 82 years. Twelve (12) patients were male and 24 female. The diameter of the stenosis was less than 13 mm in 18 of the patients and 11 patients carried colostomy. RESULTS: All 36 patients were subjected to a total of 113 dilatation sessions. The average number of sessions per patient for patients with anal stenosis was 2.5 and for patients with colorectal stenosis, 3.32. One patient with rectal stenosis required 21 sessions to achieve final objective. The result achieved was good in 31 patients, less than satisfactory in 3 patients and bad in one patient, who presented a stenosis which was over 5 cm long. We lost track of a patient in the follow up stage. Success in closing the colostomy was achieved in 9 patients, while one presented a complication due to the procedure (cervical emphysema) which remitted with medical attention. CONCLUSIONS: Endoscopic dilatation offers, through its different techniques, a safe and efficient method for the treatment of benign stenosis of the anus, rectum and colon and must be considered as a first class tool for the treatment of this kind of pathologies.

Chronic intestinal pseudoobstruction as a possible sequel to encephalitis.

A patient is reported who presented with a typical intestinal pseudoobstruction syndrome. Before this illness, the patient had suffered from measles encephalitis at the age of 15 months. A postencephalitic syndrome was present which included severe mental retardation, parkinsonism, and epilepsy. There were no relatives with a similar disease. Clinically, there was a frank recurrent pseudoobstruction syndrome with occasional diarrhea. Radiographic barium studies showed delayed transit, hypomotility of the intestines, and gross distension of the esophagus, stomach, small intestine, and colon. Histological examination of the gastrointestinal tract revealed a normal appearance of the mucosa; however, there was a hypertrophic muscle layer with abnormalities of the plexuses. Both the submucosal and the myenteric plexuses were reduced in number and size. They showed a decreased number of ganglion cells, proliferation of Schwann cells and infiltration by lymphocytes. The abnormalities were most strikingly present in the esophagus and the small intestine. The intestinal neuropathy resulting in clinical pseudoobstruction is proposed to be part of the generalised neurological pathology as a late sequel to the measles encephalitis.

Usefulness of transesophageal echocardiography in the diagnosis of conditions mimicking aortic dissection.

Between September 1987 and April 1989, forty patients suspected to have aortic dissection were evaluated by transesophageal echocardiography. Aortic dissection was identified in 18 patients. This study evaluated the ability of transesophageal echocardiography in the assessment of the 22 patients in whom aortic dissection was not found. A range of pathologic conditions was diagnosed in these patients. Five patients had ischemic heart disease when they were initially seen. Among the remaining 17 only one patient had a normal aorta. Aortic disease was present in the other 16 patients with aortic dilatation in 10. Atheromas were detected in seven patients with concomitant aortic dilatation in five of them. An extrinsic aortic mass was present in two patients. Transesophageal echocardiography correctly identified an anastomotic leak at the site of left coronary artery implantation in a patient with a recent Bentall procedure, and a large mobile clot within the proximal descending aorta in a patient with blunt chest trauma. These findings obviated the need for other tests in 15 patients and led to surgery in four with no ancillary tests performed in three of them. Thus transesophageal echocardiography has an important role in assessing patients with suspected dissection. Aortic disease is common even in patients in whom aortic dissection is excluded, and some of the conditions can be just as life-threatening as dissection. Transesophageal echocardiography not only reliably identifies dissection but can also detect luminal and extraluminal diseases not adequately visualized by other modalities.

Manual dilatation of the anus.

A group of 100 consecutive patients undergoing manual dilatation of the anus between 1980 and 1983 were reviewed retrospectively by examining the clinical presentation, diagnosis, treatment and outcome. Anal fissure was diagnosed in 46 patients, 22 had either first- or second-degree haemorrhoids, and stenosis of the anal canal was identified in seven. Manual dilatation of the anus was performed on 25 patients in the absence of a diagnosis. Dilatation failed to treat 26 anal fissures successfully. Where it was employed alone in ten cases of haemorrhoids and seven of anal stenosis, manual dilatation failed to cure seven and five patients respectively. Of the patients with no diagnosis, 23 were relieved of their symptoms following dilatation. Episodes of incontinence occurred in 27 patients, 21 of whom were female. There should be a reduced role for manual anal dilatation in the treatment of common anorectal disorders.

Nonmalignant venographic abnormalities of the inferior vena cava.

Displacement of the inferior vena cava, impressions made by adjacent structures, or intraluminal filling defects mat indicate retroperitoneal tumor growth. However, similar changes may be caused by nonmalignant normal or pathological conditions. The authors illustrate several such cases seen among 1,428 examinations performed during a three-year period.

Red degeneration of uterine leiomyoma: MR appearance.

OBJECTIVE: Red degeneration (hemorrhagic infarction) of uterine leiomyoma can cause acute abdominal pain. This study was undertaken to identify MR features useful in diagnosing this rare complication of uterine leiomyoma. MATERIALS AND METHODS: Magnetic resonance imaging from five patients symptomatic for 7 to 20 days with pathologic confirmation of red degeneration was retrospectively evaluated and correlated with histopathologic findings. RESULTS: The lesions had a common MRI appearance: hyperintense rim on T1-weighted imaging (WI) and hypointense rim on T2-WI. These findings corresponded with numerous dilated vessels filled with red blood cells at the periphery of the lesion. The signal characteristics of the rim are best explained as an effect of abundant intracellular methemoglobin in these vessels. CONCLUSION: Recognition of these characteristics may help radiologists differentiate symptomatic red degeneration from other clinical conditions that need surgical interventions.

Acquired immunodeficiency syndrome in a patient with no known risk factors: a pathological study.

We present the pathological findings in a case of acquired immunodeficiency syndrome (AIDS) in a patient with no known risk factor. Postmortem examination showed klebsiella lung abscess, generalised cytomegalovirus infection, cerebral toxoplasmosis, and a primary cerebral lymphoma. An additional feature was the presence of dilatation of the intrahepatic large bile ducts in association with an atypical distribution of cytomegalovirus. The relation between this case and previously reported cases of AIDS is discussed.

Gruentzig balloon catheter dilation for acquired bronchial stenosis in an infant.

A long stricture of the left main bronchus, which was resistant to the traditional methods of treatment, developed in a 992-gm twin who was ventilated for 114 days. The patient had two bronchial dilations with the Gruentzig balloon catheter placed under fluoroscopic control and inflated to 6 atm of pressure. The treatment was well tolerated by the patient, and one year after the Gruentzig balloon dilation she had a normal chest roentgenogram. Gruentzig balloon catheter dilation is a new technique for repairing bronchial stenosis in infancy without major intrathoracic surgical intervention.

Endoscopy: a minimally invasive procedure for diagnosis and treatment of diseases of the salivary glands. Six years of practical experience.

During a 6-year period we did a total of 72 videoendoscopies of the salivary glands and their associated ductal systems. This minimally invasive procedure is associated with little morbidity and discomfort. The main indication was sialolithiasis of the submandibular and parotid glands. Sialoendoscopy was used not only for diagnosis of radiolucent calculi but also for simultaneous removal of calculi. Sialoendoscopy was also of benefit in the diagnosis and treatment of other diseases of the salivary glands. Even patients with chronic sialadenitis could be helped with endoscopic dilatation of the causative sialostenosis, thereby enabling us to conserve the gland.
