We report a case of intra-gallbladder hemorrhage secondary to blunt abdominal trauma in a patient with liver cirrhosis. A 58-year-old man was admitted to a local hospital with persistent right upper quadrant abdominal pain. Anemia was detected, and computed tomography (CT) revealed a high-density mass in the gallbladder lumen. He was transferred to our hospital because a gallbladder tumor was suspected. He had a history of habitual alcohol abuse and had sustained blunt abdominal trauma in the right upper quadrant 29 days before admission to our hospital (4 days before to the admission local hospital). The intra-gallbladder high-density mass depicted on the CT scan, observed as non-shadowing low-level echoes, was deemed to represent a blood clot on ultrasonography (US) performed 31 days after the trauma. US-guided percutaneous transhepatic gallbladder aspiration and cholecystography confirmed the presence of an old blood clot in the lumen. Because of the patient's persistent pain, a cholecystectomy was performed. The distended gallbladder was filled with old clotted blood.

To evaluate the validity and complications of modifying the distal splenorenal shunt (DSRS) by performing splenopancreatic disconnection (SPD), hemodynamic changes in the portal system were assessed by visceral angiography in 93 patients with nonalcoholic portal hypertension during early postoperative follow-up after DSRS. There were 40 patients who underwent DSRS alone and 53 who underwent DSRS plus SPD. Early follow-up angiography showed that portal vein perfusion was well maintained, and that the diameter of the portal vein had decreased significantly by the same degree in both groups. Hepatofugal collaterals for the shunt had developed to a greater extent in the DSRS group, while they were almost completely absent in the DSRS with SPD group. Nevertheless, partial portal vein thrombosis was not detected in the DSRS group, although it was seen in seven (13.2%) of the patients who underwent DSRS plus SPD, in whom the left proximal splenic vein was not visible. The proximal splenic vein was seen in significantly less of the DSRS with SPD patients (47.2%) than the DSRS group patients (85%). In conclusion, SPD more effectively prevented the early postoperative development of collateral pathways for the shunt compared with standard DSRS; however, the possible stagnation of blood flow in the left proximal splenic vein may predispose to a risk of partial portal vein thrombosis developing during the early postoperative period after DSRS with SPD.

The distal splenorenal shunt (DSRS) is the recommended procedure for selective variceal decompression, but its use may be limited in patients who have undergone left nephrectomy, those with an anatomically aberrant relationship between the splenic and left renal veins, and those whose preoperative angiographic findings suggest a risk of developing postoperative renal vein hypertension. For these clinical situations, the selective distal splenocaval shunt (DSCS) is a useful alternative to the DSRS. However, the metabolic consequences of the DSCS have not yet been studied in detail and therefore, using a canine model, the metabolic changes following the DSCS and the portacaval shunt (Eck) were compared. The metabolic changes observed following the Eck were hyperammonia and amino acid imbalance, while those following the DSCS were similar to those of the control dogs. In terms of the hepatic adenosine triphosphate level, which reflects hepatic mitochondrial function, the DSCS dogs were also similar to the control dogs. These data suggest that there was no metabolic disadvantage of the DSCS compared to the control.
