METHODS: We reviewed 9 patients who underwent transcatheter arterial embolization (TAE) for the ruptured hepatic artery pseudoaneurysm following major hepato- biliary pancreatic surgery between June 1992 and April 2006. We paid special attention to the extrahepatic arte- rial collaterals to the liver which may affect post-TAE liver damage and patient outcome. RESULTS: The underlying diseases were all malignan- cies, and the surgical procedures included hepatopancre- atoduodenectomy in 2 patients, hepatic resection with removal of the bile duct in 5, and pancreaticoduodenec- tomy in 2. A total of 11 pseudoaneurysm developed: 4 in the common hepatic artery, 4 in the proper hepatic artery, and 3 in the right hepatic artery. Successful he- mostasis was accomplished with the initial TAE in all patients, except for 1. Extrahepatic arterial pathways to the liver, including the right inferior phrenic artery, the jejunal branches, and the aberrant left hepatic artery, were identified in 8 of the 9 patients after the completion of TAE. The development of collaterals depended on the extent of liver mobilization during the hepatic resection, the postoperative period, the presence or absence of an aberrant left hepatic artery, and the concomitant arte- rial stenosis adjacent to the pseudoaneurysm. The liver tolerated TAE without significant consequences when at least one of the collaterals from the inferior phrenic ar-tery or the aberrant left hepatic artery was present. One patient, however, with no extrahepatic collaterals died of liver failure due to total liver necrosis 9 d after TAE. CONCLUSION: When TAE is performed on ruptured hepatic artery pseudoaneurysm, reduced collateral path- ways to the liver created by the primary surgical proce- dure and a short postoperative interval may lead to an unfavorable outcome.展开更多

Although there is literature regarding gender differences in healthcare expenditure in India, there is no data regarding gender differences in hospital stay, hospital seeking behaviors and mortality. <strong>Aim:</strong> To evaluate the Gender differences in a hospital seeking behavior, mortality and hospital stay. <strong>Methods:</strong> We prospectively analyzed, from a retrospective database, all patients who underwent surgical gastrointestinal, hepato-biliary, pancreatic and splenic surgeries from 1996 to 2018 in our unit. Patients were divided into groups based on gender, admission time period and priority of admission i.e., elective or emergency. Both the gender groups were compared with respect to total procedures done, hospital stay and mortality. Organ specific mortality was calculated as proportions, was analyzed and compared between the groups. Time trends of the same were observed and compared. <strong>Results:</strong> Of 12,411 patients, 7979 (64.3%) were males and 4432 (35.7%) were females. 9191 (74.1%) patients underwent elective procedures whereas 3220 (25.9%) had emergency procedures (<strong>p ≤ 0.001</strong>). Overall mortality was higher in males (n = 473, 5.92%) in comparison to females (n = 185, 4.17%) (p ≤ 0.001). Majority of surgeries in males were of small intestine (22.5%) in which small bowel resection was most commonly done (5.4%), whereas, gallbladder and biliary surgeries (27.4%) were the most common in females in which laparoscopic cholecystectomy was most commonly done (5.8%). Median hospital stay was higher in males (10 days vs 9 days), (<strong>p ≤ 0.001</strong>). Mortality was higher in females in all organ categories except in liver (6.34% vs 2.7%), pancreas (37.3% Vs 18.3%) and spleen (3.38% Vs 1.62%) where mortality was higher for male gender. Highest mortality for females was in small intestinal surgery (34%) and for males, it was pancreatic surgery (37.3%). Highest mortality in males was emergency open pancreatic necrosectomy (21.6%) and that in females was emergency small intestinal surgery (11.9%). Although the number of surgeries in females increased over time (380 in 1996-1999 Vs 951 in 2016-2018), the proportion remained constant (36.3% Vs 38.3% in 1996-1999 and 2016-2018 respectively). <strong>Conclusion:</strong> We conclude that mortality is found to be higher in males after gastrointestinal surgery, which may be explained by the fact that hospital seeking behavior is more in males though it is fairly increasing in females in the recent years.展开更多

Recent reports have indicated that a 3-dimensional(3D) reconstructed imaging system would be useful for understanding the liver anatomy before surgery. We have investigated a novel method that fuses MDCT and MRCP images. This novel system easily made it possible to detect the anatomical relationship between the vessels and bile duct in the portal hepatis. In this report, we describe a very rare case of extrahepatic cholangiocarcinoma associated with an accessory bile duct from the caudate lobe connecting with the intrapancreatic bile duct. We were unable to preoperatively detect this accessory bile duct using MDCT and MRCP. However, prior to the second operation, we were able to clearly visualise the injured accessory bile duct using our novel 3D imaging modality. In thisreport, we suggest that this imaging technique can be considered a novel and useful modality for understanding the anatomy of the portal hepatis, including the hilar bile duct.展开更多
