Pneumatosis [correction of Pneumocystis] cystoides intestinalis with pneumoperitoneum and pneumoretroperitoneum in a patient with extensive chronic graft-versus-host disease.
(1/62)
Pneumatosis cystoides intestinalis is a rare finding of intramural gasfilled cysts in the bowel wall and sometimes free air in the abdomen. A few conditions are reported to cause this disease, one of them being immunosuppression. We describe a 50-year-old Caucasian male with extensive chronic graft-versus-host disease (GVHD) of the gut and skin who developed PCI with pneumoperitoneum and pneumoretroperitoneum. To our knowledge, this is the first report of PCI occurring in a patient with active chronic GVHD which resolved spontaneously. (+info)
Paralytic ileus accompanied by pneumatosis cystoides intestinalis after acarbose treatment in an elderly diabetic patient with a history of heavy intake of maltitol.
(2/62)
An 87-year-old woman, diagnosed with diabetes mellitus at age 73, exhibited abdominal distention and appetite loss in March 1998. She had received acarbose as well as 5 mg per day of glibenclamide and had habitually used about 100 g of maltitol daily from 1997. She was diagnosed as having paralytic ileus accompanied by pneumatosis cystoides intestinalis (PCI). This condition subsided quickly with discontinuation of diet or cessation of acarbose and maltitol usage. The patient's condition appears to be attributable to increased gas levels produced by fermentation of disaccharides and maltitol. Decreased intestinal motility may be a result of pre-existing diabetic autonomic neuropathy and hypothyroidism. The patient's clinical course suggests that paralytic ileus and PCI should be listed as rare side effects of alpha-glucosidase inhibitors and that the drug should be used with great caution for those who consume non-digestive sugar substitutes.

Pneumatosis cystoides intestinalis treated with hyperbaric oxygen therapy: usefulness of an endoscopic ultrasonic catheter probe for diagnosis.
(3/62)
A 67-year-old woman was admitted to our hospital with a complaint of abdominal pain. Barium enema examination and colonoscopy showed numerous round polypoid lesions covered with normal mucosa in the area from the ascending colon to the splenic flexure. Endoscopic ultrasound examination with an ultrasonic catheter probe revealed a strong echo with distal acoustic shadowing in the third layer of the diseased colonic wall, which suggested the presence of gas in the submucosa. The gaseous cysts disappeared completely after hyberbaric oxygen therapy at 2 to 3 atmospheres absolute (60 minutes, twice a day) for 30 consecutive days. (+info)
Necrotizing enterocolitis in the newborn: operative indications.
(4/62)
Fifty-two premature, low birth weight infants presented mainly in the first week of life with sudden manifestations of intestinal ileus and an x-ray picture of pneumatosis intestinalis. Twenty-two of 32 patients treated with gastric decompression, antibiotics, intensive supportive therapy and intravenous hyperalimentation survived. Twenty other patients had progression of their disease and required operation. Twelve of these patients survived. Review of this material indicated that some medically treated patients might have survived if they had been operated upon. Indications for operation included free perforation and clinical signs of deterioration. Abdominal physical findings and x-rays were not reliable except as signs of far advanced pathology. Confirmation of ascites by paracentesis and gram stain of fluid was helpful when present. If patients were adequately treated and then developed sudden hyponatremia or progressive acidosis, they invariably had gangrenous bowel and required operation. The most striking finding was that a sudden, profound drop in the platelet count to levels below 100,000 reliably predicted the presence of gangrenous bowel and the need for operation. Other clotting studies indicated that disseminated intravascular coagulation is an important accompaniment of NNE with the complication of bowel gangrene prior to perforation. Gastrostomy and resection of involved bowel with staged anastomosis proved to be the most successful form of surgical management. Overall suvival was 66 per cent. (+info)
Acute pneumatosis cystoides intestinalis following allogeneic transplantation -- the surgeon's dilemma.
(5/62)
Pneumatosis cystoides intestinalis (PCI) is still a poorly understood phenomenon, currently considered to result from primary mucosal insult from varying causes. We report a case of severe PCI in a patient with chronic GVHD after bone marrow transplantation (BMT) performed to treat secondary AML. Post BMT, the patient suffered acute intestinal and cutaneous GVHD, eventually developing intestinal and biopsy-proven cutaneous chronic GVHD, which necessitated continuous steroid therapy. Chronic pancreatitis associated with GVHD was diagnosed by explorative surgery in February 2000 on the basis of increasing epigastric discomfort, tumour marker (CA 125) increase and the CT finding of a suspicious mass in the pancreas. Readmission occurred in April 2000 for rapid onset of inferior abdominal pain with distinct peritoneal signs. Relaparotomy, deemed necessary on the grounds of both clinical and radiological findings, revealed marked PCI of the ascending and transverse colon and attached mesentery in an otherwise intact gastrointestinal tract. Post-operative reconvalescence was uneventful, with no clinical or radiological recurrence of PCI in the following 10 months. In the context of a review of the relevant literature, this case report illustrates the complex underlying pathophysiology, and difficulty in making a differential diagnosis and treating PCI. (+info)
Pneumatosis cystoides intestinalis, four cases of a rare disease.
(6/62)
Pneumatosis cystoides intestinalis (PCI) is a disease in which small gas-filled cysts appear in the intestinal wall. Four cases presented here demonstrate the diversity of the associated diseases. In two of the patients constipation probably played a role; in the third patient decreased colonic motility, elevated intestinal pressure and increased mucosal permeability in the context of enteritis treated with codeine was the underlying problem; in the fourth high protein feeding and bowel ischaemia was diagnosed. Various aetiologies are presented in the literature. There is no specific history and physical or laboratory findings do not help to diagnose PCI. Plain abdominal film, ultrasound, computer tomography, magnetic resonance imaging, barium contrast studies and/or endoscopy may be necessary for diagnosis. Therapy is based on enhancing partial oxygen pressure in the bowel wall. PCI usually runs a benign course. (+info)
Pneumatosis intestinalis associated with immune-suppressive agents in a case of minimal change disease.
(7/62)
We report treatment of a 38-year-old man with minimal change disease (MCD) who developed pneumatosis intestinalis (PI) during administration of immune-suppressive agents. His immunosuppressive medication had been tapered to 15 mg/day of prednisolone. MCD was steroid-resistant type. Abdominal examination and laboratory studies were not clinically remarkable. Radiologic findings were consistent with PI. Abnormal air accumulation was noted in the bowel, peritoneum, mediastinum and retroperitoneum. Conservative therapy with oxygen and metronidazole improved the PI symptoms. In 1993, a case of PI with nephrotic syndrome following steroid treatment was reported in Japan. However this is only the second case reported in the literature, and the first in English. (+info)
We describe an unusual case of pneumatosis cystoides intestinalis (PCI) in a patient with chronic pulmonary disease. A 79-year-old woman was hospitalized due to abdominal fullness and bowel habit change. Colonoscopy revealed numerous round cystic lesions in the sigmoid colon, which bled easily on contact. Due to persistent local peritonitis, a left hemicolectomy with primary anastomosis was performed. The patient has done well in the 12 months following surgery. (+info)
