Volvulus of the spleen is a complication of a previous congenital anomaly consisting basically in the absence of supporting structures of the spleen. Clinically, it is an extremely rare complication. It may present as an acute abdomen. The search of the literature that we conducted does not show any such case being the cause of portal hypertension. This motivated this case report. The patient was treated surgically and this cured the patient.

There are few reported cases of acute portal vein thrombosis presenting as an acute abdomen in adolescent age group. Most published series concern chronic extrahepatic portal vein thrombosis. Acute portal vein thrombosis is rare, but can develop into serious complications. Hence, prompt diagnosis and heparinization can prevent the development of lethal complications such as venous gangrene of the bowel and portal hypertension.

Wandering spleen (WS) is a rare condition where the spleen, free from its ligaments, is allowed to move inside the abdomen predisposing the patient to life-threatening complications due to torsion of the vascular pedicle; splenic infarction, portal hypertension, bleeding and acute abdomen may occur. WS is rarely suspected at presentation since symptoms are usually not specific and definitive diagnosis is usually reached only by imaging technologies such as color flow ultrasonography and angio-spiral computer tomography. A 42-year-old woman was referred to our institute from the Emergency and Accident ward, complaining of a sudden onset of sharp abdominal pain together with nausea and vomiting. At examination a large, painful mass was present on the left middle-lower abdominal quadrant. A pelvic spleen was revealed at abdominal ultrasonography (US) and confirmed by abdominal CT. Emergency laparoscopy was carried out. The spleen was barely attached to the peritoneum of the anterior abdominal wall, covered by the greater omentum, the small bowel, and the transverse colon. Once mobilization of the spleen was concluded, the vascular pedicle appeared torted and thrombosed and laparoscopic splenectomy was performed. The patient was discharged on the 4th postoperative day with no complications. To date, only 5 cases of laparoscopic approach to WS have been reported. A review of the literature confirms that the reduction of postoperative stay, wound complications, and overall morbidity and a faster return to normal activity make laparoscopy the "gold standard" approach to the spleen as for treatment of many hematological disorders or more unusual splenic diseases.

The authors present case of patient with biliary stent dislocation after chest injury and fracture of VIII. rib. Polymorbid patient with cirrhosis, chronic pancreatitis, portal hypertension (Child Plugh B) and biliary stent insertion came with acute abdominal pain and inflammatory signs. Progressive signs of acute abdomen have led to laparotomy. Perforation of duodeno-jejunal-loop due to dislocated biliary stent, small loop adhesions and thickened intestine wall were found. Postsurgical period was complicated with obstructive ileus, cholecystitis and cholangiolitis and the second biliary stent was inserted. Present-day status of the patient is satisfactory.

The thrombophilia which can be either congenital or acquired in adult life has major implications in the abdominal vessels. The resulting portal vein thrombosis, Budd-Chiari syndrome and mesenteric vein thrombosis have a variety of consequences ranging from acute abdomen to chronic hepatomegaly and even totally asymptomatic patient in whom the only finding is pancytopenia. The complications like esophageal varices, portal gastropathy, ascites, severe hypersplenism, liver failure requiring liver transplantation are well known. Interesting features of collateral venous circulation showing itself as pseudocholangiocarcinoma sign and its possible clinical reflection as cholestasis are also known from a long time. The management strategies for these complications of intraabdominal vessel thrombosis are not different from their counterpart which is cirrhotic portal hypertension, but the prognosis is unquestionably better in former cases. In this review we presented and discussed the abdominal venous thrombosis, etiology and the resulting clinical pictures. There are controversial issues both in nomenclature, and management including anticoagulation problems and follow up strategies. In light of the current knowledge, we discussed some controversial issues in literature and presented our experience and our proposals about this group of patients.

We report a case of acute abdomen caused by nontraumatic intra-abdominal bleeding in a 38-year-old man. Emergency laparotomy revealed the source of bleeding as a vein in the right colorenal ligament. The rupture of this vein may have been attributable to shear stress after severe vomiting on the day before admission. Although the patient had a coagulation disorder secondary to early-stage liver cirrhosis, there were no signs of portal hypertension intraoperatively. This report describes an unusual cause of acute hemoperitoneum, highlighting the importance of including this life-threatening disorder in the differential diagnosis of acute abdomen of unknown origin. Its outcome is dependent on early diagnosis and prompt emergency intervention.

Pylephlebitis is defined as thrombophlebitis of the portal vein or its tributaries. It is a rare disease commonly associated with acute appendicitis and it has a high rate of morbidity and mortality. Doppler ultrasound and computed tomography scan are the methods of choice to confirm diagnosis. The most frequent long-term complication in these patients is portal vein cavernoma, with subsequent portal hypertension. An early diagnosis, timely antibiotic therapy and removal of infection are essential therapeutic measures to diminish mortality. The need for anticoagulation therapy in children remains controversial. We report on a child with acute abdomen and sepsis with a diagnosis of pylephlebitis secondary to appendiceal inflammation. The patient received long-term antibiotic therapy and subcutaneous anticoagulation. Deferred appendectomy was performed with favorably outcome.
