1/466. Separate sac of peritoneum: a case of an unusual cause of intestinal obstruction.

    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)

2/466. Spontaneous isolated lesser sac hematoma in a patient with hemophilia.

    In patients with hemophilia, hematomas in the mesentery and bowel wall have been described uncommonly. The lesser sac is a rare site of spontaneous hemorrhage even in patients with bleeding diathesis; only a single case of isolated lesser sac hemorrhage has been reported in a hemophiliac patient. We report a similar case with no history of trauma. He recovered with administration of factor viii concentrate. ( info)

3/466. Is calcifying fibrous pseudotumor a late sclerosing stage of inflammatory myofibroblastic tumor?

    Calcifying fibrous pseudotumor is a recently described distinctive lesion, characterized by the presence of abundant hyalinized collagen with psammomatous or dystrophic calcifications and a lymphoplasmacytic infiltrate. The cause and pathogenesis are unclear, but a possible relationship with other pseudotumors, like nodular fasciitis or inflammatory myofibroblastic tumor, has been proposed by some authors. However, cases with overlapping histologic features have not been reported. A 17-year-old girl with multiple peritoneal calcifying fibrous pseudotumors and inflammatory myofibroblastic tumors (inflammatory pseudotumors) is described. Some multinodular lesions showed calcifying fibrous pseudotumors next to inflammatory myofibroblastic tumors. Transitional stages between calcifying fibrous pseudotumor and inflammatory myofibroblastic tumor were also present. This case clearly illustrates a histogenetic relationship between calcifying fibrous pseudotumor and inflammatory myofibroblastic tumor, and it suggests that calcifying fibrous pseudotumor is a late sclerosing stage of inflammatory myofibroblastic tumor, at least in some cases.

4/466. Fatal polyarteritis nodosa with massive mesenteric necrosis in a child.

    polyarteritis nodosa (PAN) is a rare vasculitic syndrome in childhood. There are few reported cases of ischaemic necrosis of the intestine and even fewer survivors in adults. We report the case of a 10-year-old boy with PAN and an acute abdomen that required operative intervention. Evidence was found of mesenteric arteritis with large ischaemic segments resulting in infarction and perforation. ( info)

5/466. Celiomesenteric anomaly with concurrent aneurysm.

    We describe a rare case of a celiomesenteric anomaly with concurrent aneurysm. The patient, a 53-year-old man, had no abdominal pain or discomfort. The presence of a celiac artery aneurysm was suspected on the basis of the results of abdominal computerized tomographic scanning and echo ultrasound scanning performed because of proteinuria. Intra-arterial digital subtraction angiographic results showed the anomaly and aneurysm. Because of the risk of rupture of the aneurysm, the lesion was repaired surgically, with the placement of an interpositional prosthetic graft. We found no previous reports of celiomesenteric anomaly with concurrent aneurysm repaired with prosthetic graft. ( info)

6/466. Inflammatory cysts of the pelvic peritoneum.

    Three young women with abdominal distension due to pelvic masses were investigated using ultrasound and conventional radiographic techniques. While the latter revealed masses of soft tissue density arising from the pelvis and displacing bowel, the sonogram indicated the morphologic features of thin-walled multiloculated cysts. They were located entirely within the peritoneal cavity and contained serous to serosanguineous fluid. The mesholelial lined walls were infiltrated with chronic inflammatory cells and were adherent to chronically inflamed fallopian tubes. Although these acquired cysts are familiar to pathologists and gynecologists, the literature contains little information about them. ( info)

7/466. Laparoscopic drainage of giant lymphocele after renal transplantation.

    lymphocele is a relatively frequent complication of kidney transplantation. A 46-year-old man presented 2 years after kidney transplantation with a giant septated lymphocele. The patient underwent successful laparoscopic drainage of the collection and was discharged home on the day of the procedure. Laparoscopic drainage is a safe and effective treatment for complex lymphocele after kidney transplantation. ( info)

8/466. Transmesenteric hernia after laparoscopic-assisted sigmoid colectomy.

    BACKGROUND AND OBJECTIVES: Laparoscopic-assisted surgery has been applied for a variety of colonic surgery. The objective of this paper is to demonstrate a possible and avoidable complication of laparoscopic colonic surgery. CASE PRESENTATION: A 47-year-old woman underwent gasless laparoscopic-assisted sigmoid colectomy. On the 20th postoperative day, she developed bowel obstruction. decompression with a long tube failed to resolve the bowel obstruction. Open laparotomy was performed. Abdominal exploration revealed a loop of the small bowel incarcerated in the mesenteric defect caused by the previous operation. Adhesiolysis was performed, and the postoperative course was uneventful. DISCUSSION: Despite technical difficulty, complete closure of the mesentery after bowel resection is strongly recommended for prevention of transmesenteric incarcerated hernia after laparoscopic surgery.

9/466. Peritoneal sarcoidosis: case report and review of the literature.

    OBJECTIVES: This study was performed to report a patient with peritoneal sarcoidosis and review the literature for similar cases. methods: We described the clinical presentation, course, and outcome of the patient, and reviewed the medical literature from 1966 till 1997 using medline and the key words sarcoidosis, scar, and peritoneum. RESULTS: Our patient presented with a rapidly growing tumor-like mass at the site of an old appendectomy scar. laparoscopy showed a large peritoneal mass and multiple small peritoneal nodules that were found to be noncaseating granulomas by pathology. The medline search uncovered only 16 cases of peritoneal sarcoidosis, most of which presented with ascites. CONCLUSION: This case illustrates the need to consider sarcoidosis, in addition to infections and neoplasms, in the differential diagnosis of peritoneal nodules and exudative ascites. ( info)

10/466. Preoperative sonographic diagnosis of midgut malrotation with volvulus in adults: the "whirlpool" sign.

    Midgut malrotation and volvulus, found mostly in children, are rare and difficult to diagnose preoperatively in adults. We report 2 cases in which a 68-year-old man and a 75-year-old woman presented with intermittent cramping abdominal pain, abdominal distention, and vomiting. Abdominal sonography demonstrated wrapping of the superior mesenteric vein and bowel loops around the superior mesenteric artery (the "whirlpool sign") in both patients. Abdominal CT revealed similar findings. The diagnoses of midgut volvulus and mesenteric malrotation were made, and the patients underwent laparotomy. The man was confirmed to have duodenojejunal malrotation and volvulus, and the woman had cecal volvulus. The whirlpool sign is valuable for the preoperative diagnosis of mesenteric vessel malrotation and midgut volvulus. ( info)
