| Internal hernia is a rare condition. These hernias are classified in different categories, depending on the location of its orifice. It should be considered in cases of acute intestinal obstruction, particularly in the absence of an external hernia or in the absence of history of previous abdominal surgery. The authors report a unique case of obstruction of the small bowel, that was almost entirely wrapped in a separate peritoneal sac. ( info) |
2/942. CT findings of isolated small bowel angioedema due to iodinated radiographic contrast medium reaction. We report three cases of small bowel angioedema that showed circumferential wall thickening of the small bowel loops during infusion of iodinated contrast media. Follow-up small bowel series or computed tomography confirmed the normalized small bowel loops. When significant wall thickening of the long segment of the small bowel during infusion of contrast media is seen, radiologists should consider the possibility of isolated small bowel angioedema in spite of its rarity.

3/942. Acute small bowel obstruction due to ileal endometriosis: a case report and literature review. A young women presented with non-resolving acute small bowel obstruction and was found to have a stricture in the distal ileum at laparotomy. Histologically this was due to endometriosis. Resection of the involved segment gave excellent results. ( info) |
| Septic thrombophlebitis of the portal vein, or pylephlebitis, is an extremely rare complication of intraabdominal infection, most commonly caused by diverticulitis (1). The following case report describes a patient without previous significant medical history presenting with painless jaundice and presumed malignancy. Workup revealed pylephlebitis due to an ileal abscess secondary to Crohn's disease. The patient was successfully treated with broad spectrum antibiotics and terminal small bowel and right colon resection. To our knowledge, this is the first reported case of Crohn's disease diagnosed after presentation with pylephlebitis. ( info) |
5/942. Multiple tubercular ulcer perforation of ileum in an AIDS patient: case report. intestinal perforation is an extremely uncommon complication of mycobacterium tuberculosis (MTB) infection. We report a case of hiv infection in a male injecting drug user (IDU) with intestinal tuberculosis complicated with multiple ileal perforations at the Regional Institute of Medical Sciences Hospital, Imphal, Manipur. The emergency surgical therapy supported by antitubercular drugs (ATT) and parenteral nutrition saved the life of this patient who presented in a critical state of shock. The patient manifested with extrapulmonary tuberculosis, which is one of the criteria of AIDS. The authors stress the possibility that in future, tubercular complication till now considered atypical, may become more frequent. ( info) |
6/942. Transvaginal evisceration of small bowel after radical hysterectomy and pelvic lymphadenectomy. Vaginal evisceration is a rare event. This case report describes a 45-year-old woman who presented 8 days following radical hysterectomy and lymph node dissection for stage 1B squamous cell carcinoma of the cervix with small bowel evisceration through the vagina. She was treated by laparotomy and resection anastamosis of a discolored part of the distal ileum. ( info) |
7/942. Transient pseudo-hypoaldosteronism following resection of the ileum: normal level of lymphocytic aldosterone receptors outside the acute phase. Pseudo-hypoaldosteronism (PHA) is due to mineralocorticoid resistance and manifests as hyponatremia and hyperkalemia with increased plasma aldosterone levels. It may be familial or secondary to abnormal renal sodium handling. We report the case of a 54-year-old woman with multifocal cancer of the colon, who developed PHA after subtotal colectomy, ileal resection and jejunostomy. She was treated with 6 g of salt daily to prevent dehydration, which she stopped herself because of reduced fecal losses. One month later she was admitted with signs of acute adrenal failure, i.e. fatigue, severe nausea, blood pressure of 80/60 mmHg, extracellular dehydration, hyponatremia (118 mmol/l); hyperkalemia (7.6 mmol/l), increased blood urea nitrogen (BUN) (200 mg/dl) and creatininemia (2.5 mg/dl), and decreased plasma bicarbonates level (HCO3-: 16 mmol/l; N: 27-30). However, the plasma cortisol was high (66 microg/100 ml at 10:00 h; N: 8-15) and the ACTH was normal (13 pg/ml, N: 10-60); there was a marked increase in plasma renin activity (>37 ng/ml/h; N supine <3), active renin (869 pg/ml; N supine: 1.120), aldosterone (>2000 pg/ml; N supine <150) and plasma AVP (20 pmol/l; N: 0.5-2.5). The plasma ANH level was 38 pmol/l (N supine: 5-25). A urinary steroidogram resulted in highly elevated tetrahydrocortisol (THF: 13.3 mg/24h; N: 1.4 /-0.8) with no increase in tetrahydrocortisone (THE: 3.16 mg/24h; N: 2.7 /-2.0) excretion, and with low THE/THF (0.24; N: 1.87 /-0.36) and alpha THF/THF (0.35; N: 0.92 /-0.42) ratios. The number of mineralocorticoid receptors in mononuclear leukocytes was in the lower normal range for age, while the number of glucocorticoid receptors was reduced. Small-bowel resection in ileostomized patients causes excessive fecal sodium losses and results in chronic sodium depletion with contraction of the plasma volume and severe secondary hyperaldosteronism. Nevertheless, this hyperaldosteronism may be associated with hyponatremia and hyperkalemia suggesting PHA related to the major importance of the colon for the absorption of sodium. In conclusion, this case report emphasizes 1) the possibility of a syndrome of acquired PHA with severe hyperkalemia after resection of the ileum and colon responding to oral salt supplementation; 2) the major increase in AVP and the small increase in ANH; 3) the strong increase in urinary THF with low THE/THF and alpha THF/THF ratios; 4) the normal number of lymphocytic mineralocorticoid receptors outside the acute episode.

8/942. intussusception following a baby walker injury. Serious abdominal injury as a result of a fall in a baby walker has not been previously reported. We present the case of a 13-month-old boy who developed intussusception following a fall down five stairs in a baby walker. Attempted hydrostatic reduction was unsuccessful. At operation, a bowel wall hematoma, serving as a lead point, was identified. This case adds another type of injury to the list of those previously associated with baby walker use. ( info) |
9/942. Enterovesical fistula complicating pregnancy. A case report. BACKGROUND: Enterovesical fistula is a rare cause of recurrent urinary tract infections. This condition is unusual in young people as common etiologies include diverticular disease and cancer. When an enterovesical fistula occurs in women of childbearing age, Crohn's disease is a likely cause. To our knowledge, enterovesical fistula complicating pregnancy has not been reported before. CASE: A pregnant woman with recurrent urinary tract infections was evaluated. cystoscopy was suggestive of an enterovesical fistula, which was confirmed by charcoaluria following oral charcoal administration. The prenatal course was complicated by two episodes of hemorrhagic cystitis despite antibiotic prophylaxis. The patient had an uncomplicated term spontaneous vaginal delivery. An upper gastrointestinal series performed postpartum was suggestive of Crohn's disease and confirmed an enterovesical fistula. Surgical repair was successfully performed three months following delivery, revealing Crohn's disease. CONCLUSION: Enterovesical fistula may be an unusual cause of recurrent urinary tract infections in pregnancy. In this case, enterovesical fistula was the presenting symptom of Crohn's disease.

10/942. The Rapunzel syndrome (trichobezoar) causing atypical intussusception in a child: a case report. The Rapunzel syndrome (trichobezoar) occurs when gastrointestinal obstruction is produced by a rare manifestation of a trichobezoar with a long tail that extends to or beyond the ileocecal valve. A case history of a 7-year-old girl is described. This is the eleventh patient with Rapunzel syndrome reported in the literature. The epidemiology, clinical features, diagnosis, complications, treatment, and literature are reviewed briefly. ( info) |
