1/64. 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.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/64. The role of trisomy 8 in the pathogenesis of chronic eosinophilic leukemia.A case of chronic eosinophilic leukemia (CEL) manifesting as spinal cord compression by an extradural eosinophilic chloroma in a 32-year-old Chinese man was presented, who subsequently developed extramedullary transformation at the skin and then peritoneal cavity. Cytogenetic study of bone marrow cells at diagnosis showed a clonal karyotypic abnormality of trisomy 8 ( 8), which on fluorescence in situ hybridization (FISH) was shown to be present in a clone of abnormal eosinophils, hence showing the neoplastic nature of the eosinophilic proliferation. There was another population of abnormal eosinophils that did not show 8. At blastic transformation, all blast cells in ascitic fluid were shown by FISH to harbor 8. These findings suggest that 8 in this case may have arisen from clonal evolution and is not the primary genetic event in leukemogenesis, but 8 most probably imparts a further survival advantage to the clone responsible for subsequent blastic transformation.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
3/64. Management of a patient with hepatic-thoracic-pelvic and omental hydatid cysts and post-operative bilio-cutaneous fistula: a case report.In humans, most hydatid cysts occur in the liver and 75% of these are single. Our patient was a 31 year-old male. His magnetic resonance imaging (MR) showed one cyst (15 x 20 cm) in the right lobe and three cysts (5 x 6 cm, 8 x 6 cm, and 5 x 5 cm) in the left lobe of the liver, two cysts (4 x 5 cm and 5 x 5 cm) on the greater omentum, and two cysts (15 x 10 and 10 x 10 cm) in the pelvis. The abdomen was entered first by a bilateral subcostal incision and then by a Phennenstiel incision. Partial cystectomy capitonnage was done on the liver cysts; the cysts on the omentum were excised, and the pelvic cysts were enucleated. The cyst in the right lobe of the liver was in communication with a thoracic cyst. An air leak developed from the thoracic cyst which had underwater drainage and bile drainage from the drain in the cavity of the right lobe cyst. Sphincterotomy was done on the seventh post-operative day by endoscopic retrograde cholangiopancreatography (ERCP). No significant effect on mean bile output from the fistula occurred. octreotide therapy was initiated, but due to abdominal pain and gas bloating the patient felt and could not tolerate, it was stopped on the fourth day; besides, it had no decreasing effect on bile output during the 4 days. Because air and bile leak continued and he had bile stained sputum, he was operated on on post-operative day 18. By right thoracotomy, the cavity and the leaking branches were closed. By right subcostal incision, cholecystectomy and T-tube drainage of the choledochus were done. On post-operative day 30, he was sent home with the T-tube and the drain in the cavity. After 3 months post-operatively, a second T-tube cholangiography was done, and a narrowing in the distal right hepatic duct and a minimal narrowing in the distal left hepatic duct were exposed. Balloon dilatation was done by way of a T-tube. bile drainage ceased. There was no collection in the cavity in follow-up CT scanning, so the drain in the cavity, and the drainage catheter in the right hepatic duct were extracted. Evaluation of the biliary ductal system is important in bilio-cutaneous fistulas, and balloon dilatation is very effective in fistulas due to narrowing of the ducts.- - - - - - - - - - ranking = 5keywords = cavity (Clic here for more details about this article) |
4/64. Gliomatosis peritonei as a complication of a ventriculoperitoneal shunt: case report and review of the literature.Gliomatosis peritonei, the implantation of neuroglial tissue upon the peritoneal surfaces, is a rare event most often associated with solid or immature teratomas of the ovary in young girls. The authors report a case of a 10-month-old girl with a ventriculoperitoneal shunt (VPS) who presented with bilateral inguinal hernias. herniorrhaphy was uneventful. Microscopic examination of the hernia sacs showed exuberant mesothelial hyperplasia containing multiple nests of differentiated glial tissue. Subsequent computed tomography and laparoscopy disclosed normal ovaries with no evidence of intraabdominal or pelvic abnormalities. Gliomatosis peritonei in this case was attributed to transport of glial tissue from the cerebrospinal fluid into the peritoneal cavity via the shunt. With the exclusion of an ovarian germ cell neoplasm and in the presence of a VPS, the clinical course with regard to the glial implants in these children is uneventful. If it is appreciated that gliomatosis peritonei may be a complication of a VPS, an extensive clinical evaluation generally is unnecessary.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
5/64. Congenital pleuroperitoneal communication in a patient with pseudomyxoma peritonei.BACKGROUND AND OBJECTIVES: pseudomyxoma peritonei syndrome is a rare disease arising from a perforated appendiceal adenoma. The syndrome is characterized by progressive accumulation of mucinous ascites and tumor within the peritoneal cavity. Direct extension of pseudomyxoma peritonei to the pleural cavity is uncommon and has been associated with surgical penetration of the diaphragm at the time of cytoreduction. methods: We review the case of a patient who presented with mucoid peritoneal and pleural fluid consistent with spontaneous pleural spread of pseudomyxoma peritonei. RESULTS: Surgical exploration confirmed direct pleuroperitoneal communication by macroscopic diaphragmatic fenestration. CONCLUSIONS: This is a rare phenomenon. We outline a therapeutic approach to be applied when pleural involvement is suspected in patients with pseudomyxoma peritonei syndrome.- - - - - - - - - - ranking = 2keywords = cavity (Clic here for more details about this article) |
6/64. Idiopathic segmental infarction of the greater omentum successfully treated by laparoscopy: report of case.Idiopathic or spontaneous segmental infarction of the greater omentum (ISIGO) is a rare cause of acute right-sided abdominal pain. The symptoms simulate acute appendicitis in 66% of cases and cholecystitis in 22%. Progressive peritonitis usually dictates laparotomy, and an accurate diagnosis is rarely made before surgery. The etiology of the hemorrhagic necrosis is unknown, but predisposing factors such as anatomic variations in the blood supply to the right free omental end, obesity, trauma, overeating, coughing, and a sudden change in position may play a role in the pathogenesis. We present herein the case of a 37-year-old man in whom ISIGO, precipitated by obesity and overeating, was successfully diagnosed and treated by laparoscopy. Resection of the necrotic part of the greater omentum is the therapy of choice, and ensures fast recovery and pain control. Serohemorrhagic ascites is a common finding in ISIGO, and careful exploration of the whole abdominal cavity should be performed. The laparoscopic approach allows both exploration and surgical intervention.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
7/64. Is the loss of gallstones during laparoscopic cholecystectomy an underestimated complication?Laparoscopic cholecystectomy entails an increased risk of gallbladder rupture and consequent loss of stones in the abdominal cavity. Herein we report the case of a 51-year-old male patient, who underwent laparoscopic cholecystectomy 2 years before presentation to our hospital. He had experienced tension sensation and epigastric pain since 4 months postoperatively. A well-defined epigastric mass, which was hard and painful on palpation, was detected and later confirmed by ultrasonography and CT scan.Explorative laparotomy revealed a mass in the area of the gastrocolic ligament,resulting from biliary gallstones in conjunction with a perimetral inflammatory reaction. A review of the literature showed that the incidence of gallbladder lesions during laparoscopy is 13-40%. In order to prevent this complication, meticulous isolation of the gallbladder, proper dissection of the cystic duct and artery, and careful extraction through the umbilical access are required. ligation after the rupture or use of an endo-bag may be helpful. The loss of gallstones and their retention in the abdominal cavity should be noted in the description of the surgical procedure.- - - - - - - - - - ranking = 2keywords = cavity (Clic here for more details about this article) |
8/64. Intraperitoneal abscess after an undetected spilled stone.gallbladder perforation with loss of calculi in the abdomen is frequent during laparoscopic cholecystectomy and can cause serious late complications. We report on a 65-year-old woman who underwent laparoscopic cholecystectomy for gallbladder empyema, during which a stone spilled into the peritoneal cavity. The spilled gallstone was not noticed during the initial operation. Three months later, she reported left upper quadrant pain of recent onset without associated symptoms such as fever, nausea, or weight loss. On examination, a palpable 2-cm tender subcutaneous mass was found. Abdominal ultrasound demonstrated an incarcerated hernia, and computed tomography (CT) scan showed an intraperitoneal abscess located in the back of the anterior abdominal wall in the left upper quadrant, which contained a recalcification figure. The patient was brought to surgery, at which time an incision was made over the mass. A chronic abscess in the back of the abdominal wall, also spreading into the subfascial space, was drained, and purulent material was obtained with a large stone, 2.8 cm in diameter, which had become lodged in the rectus abdominis after an undetected stone spillage during laparoscopic cholecystectomy. The patient continued receiving antibiotic treatment for 7 days, recovered well, and was discharged 7 days after drainage of the abscess.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
9/64. Laparoscopic diagnosis and management of Fitz-Hugh-Curtis syndrome: report of three cases.Perihepatic adhesions between the liver capsule and the diaphragm or the anterior peritoneal surface characterizes Fitz-Hugh-Curtis syndrome (FHCS). FHCS is an extrapelvic manifestation of pelvic inflammatory disease and usually refractory to medical treatment and surgical intervention. With the increased incidence of pelvic inflammatory disease, chronic pelvic pain and sequalae of the process are becoming more common. Herein, we report 3 patients with pelvic inflammatory disease in whom medical treatment failed initially and FHCS was diagnosed via laparoscopy. Laparoscopic lysis of pelvic and perihepatic adhesions, irrigation of the abdomino-pelvic cavity, and antibiotics treatment after surgery successfully relieved these patients' symptoms. FHCS is not a new syndrome but most gynecologists might neglect this condition. laparoscopy is a less invasive procedure than exploratory laparotomy. We recommend laparoscopy in patients with lower abdominal and right upper quadrant discomfort when other organic disease has been ruled out and medical treatment has failed to relieve symptoms.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
10/64. Ultrasonographic features of pseudotumorous form of ascariasis.We report the ultrasonographic findings of a 60 year old woman with pseudotumorous form of ascariasis. Real-time ultrasonographic examination using a curved array transducer revealed grossly thickened small bowel loops, multiple small circular deposits throughout the peritoneal cavity, and a moderate amount of ascites. The English literature on the different forms of abdominal ascariasis is reviewed. Specific signs, which include the 'strip' sign, the 'four-lines', 'inner tube', or 'double tube' sign, the 'bull's eye' or 'target' sign, a 'worm mass' or 'spaghetti-like' appearance, and the 'zig-zag' sign can be present in any form of abdominal ascariasis, as they represent the image of the ascaris worms visualized under ultrasonographic examination. However, the non-specific signs are not peculiar to A. lumbricoides infections, but are results of secondary changes due to A. lumbricoides infections in the corresponding organs.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
