1/4. Previous appendicitis may affect peritoneal overlap of the mesh in laparoscopic inguinal hernia repair.Laparoscopic inguinal hernia repair is now increasingly performed in bilateral and recurrent groin hernias. The avoidance of direct exposure of the commonly used meshes to the abdominal viscera is considered essential to reduce the risk of bowel adhesions. We report a case of bilateral inguinal hernia repair in a patients who had had an appendectomy performed 8 years earlier for a perforated appendicitis. Probably as a result of previous inflammation, any attempt to dissect the preperitoneal layer in the right side resulted in peritoneal lacerations. Since the peritoneum could not be used to cover the mesh, we decided to position an expanded polytetrafluoroethylene (e-PTFE) mesh to avoid postoperative adhesions. The mesh was fixed with tacks to the symphysis pubis, Cooper's ligament, the ilio-pubic tract, and the transversalis fascia 2 cm above the hernia defect. This case suggests that in patient with previous appendicitis, a difficult preperitoneal dissection can be expected. In such cases, especially in young patients for whom future surgical operations cannot be excluded, any attempt to reduce adhesions is justified. At the present time, the use of e-PTFE meshes, which induce no tissue reaction, is a good option in this situation.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
2/4. Mesothelial inclusion cysts (so-called benign cystic mesothelioma)--a clinicopathological analysis of six cases.The report presents six cases of mesothelial inclusion cysts (MIC), detected in five females (22-53 years of age) and one male (47 years old). The lesions were unifocal (four cases) and multifocal (two cases), and were located on the surface of the peritoneum in the cul de sac, on the intestines, urinary bladder, uterine adnexa, also involved round ligament within the pelvis and in the inguinal canal (one patient). Additionally, in one female, small cysts, free-floating in the peritoneal cavity were present. In three patients, clinical signs resulted directly from the presence of MIC. One female had been 7 years previously operated on due to endometrioid ovarian cysts. Apart from MIC, three patients presented with concomitant diseases: appendicitis (two cases), peritoneal pseudomyxoma or primary ovarian carcinoma. Gross appearance: the lesions were polycystic, the surgical materials ranging from three fragments measuring 0.5 cm each to seven fragments, with the maximum size of 14x6 cm. The cysts were from microscopic size to 2 cm in diameter, the majority were thin-walled, semitranslucent, filled with clear or yellowish fluid or gelatinous contents. In one case, the cyst walls were thicker and showed intense inflammatory lesions and fibrinous exudate. Microscopically, the majority of cysts were lined with a single layer of flattened or cuboid mesothelial cells (CK , calretinin ). In two patients, the mesothelium demonstrated diffuse squamous cell metaplasia; in one individual, the cells focally formed small papillae and were vacuolated. No mucus was observed either in the cytoplasm or outside the cells. Immunohistochemical reactions to CEA, ER, PR and MIB-1 were negative. Intramural proliferations and intracystic detached clumps of cells showed both mesothelial cells (without any mitotic activity and signs of atypia) and macrophages (CD68 ). To date, the follow-up has been 7 years and 3 years in two individuals, and from 1 to 7 months in the remaining three patients--all of them are free from recurrent disease. One female failed to report for follow-up examinations. The report also presents the review of literature.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
3/4. Rare complications following colonoscopy: case reports of splenic rupture and appendicitis.BACKGROUND: appendicitis and splenic rupture are 2 rare complications of colonoscopy reported in the literature. To our knowledge splenic rupture following colonoscopy has been reported 17 times in the English-language literature and is associated with excess traction on the splenocolic ligament. appendicitis after colonoscopy has been reported only 9 times and is usually associated with obstruction of the appendiceal lumen with fecal matter during colonoscopy. methods: We present the case reports of 2 patients: a 76-year-old woman who presented in consultation 24 hours after a routine colonoscopy with massive hemoperitoneum secondary to splenic rupture, seen on computed tomographic (CT) scan, who then underwent splenectomy; the second, a 60-year-old male who presented to the emergency room 16 hours after colonoscopy with clinical and computed tomographic scan findings of acute appendicitis who underwent a laparoscopic appendectomy. RESULTS: Treatment of both patients resulted in resolution of their complications, splenic rupture and appendicitis. They both had an uneventful postoperative course and are doing well several months postoperatively. CONCLUSIONS: We report 2 rare complications of colonoscopy, splenic rupture and appendicitis. In the setting of a recent colonoscopy and abdominal pain, a high index of suspicion is needed for their diagnosis.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
4/4. Intraoperative US diagnosis of pylephlebitis (portal vein thrombosis) as a complication of appendicitis: a case report.We report a case of infectious thrombosis of the superior mesenteric vein (pylephlebitis) that was suspected preoperatively with computed tomography and confirmed at intraoperative ultrasonography as confined to the extrahepatic portal vein and superior mesenteric vein. Intraoperative ultrasonography revealed intraluminal echogenic thrombus material in the dilated superior mesenteric and extrahepatic portal veins, slightly dilated open splenic vein, and numerous venous collaterals in the hepatoduodenal ligament. When preoperative imaging studies are inconclusive, intraoperative sonography can confirm the correct diagnosis of pylephlebitis and may give valuable information about the extent of the thrombosis.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
