Blood loss, a well-known risk factor for morbidity and mortality during liver resection, occurs during parenchymal transection, so many approaches and devices have been developed to limit bleeding. Surgical technique is an important factor in preventing intraoperative and postoperative complications. The aim of the present study was to determine whether the bipolar vessel sealing device allows a safe and careful liver transection, achieving a satisfactory hemostasis thus reducing blood loss and related complications.A total of 30 consecutive patients (18 male, 12 female with a mean age of 63 years) underwent major and minor hepatic resection in which the bipolar vessel sealing device was used without routine inflow occlusion. A crush technique followed by energy application was used to perform the parenchymal transection. No other devices were applied to achieve hemostasis. The bipolar vessel sealing device was effective in 27 cases of hepatic resection. It failed to achieve hemostasis in three patients, all of whom had a cirrhotic liver. Median blood loss was 250 ml (range: 100-1600 ml), and intraoperative blood transfusions were required in five patients (17%). Mean operative time was 200 minutes (range: 140-360 minutes). There was no clinical evidence of postoperative hemorrhage, bile leak, or intraabdominal abscess. The postoperative complication rate was 17%. The bipolar vessel sealing device is a useful tool in standard liver resection in patients with a normal liver parenchyma, but its use should be avoided in cirrhotic livers.
Solitary metastases from gastric cancer should be treated surgically and confer a better prognosis. Surgical resection should provide microscopically negative margins (R0). A new prognostic factor, the presence of a pseudocapsule, may be associated with improved prognosis.
Portal thrombosis should be suspected in patients with fever or abdominal pain after splenectomy. Patients with myeloproliferative disorders and hemolytic diseases are at higher risk, as well as patients with marked splenomegaly. A high index of suspicion, early diagnosis, and prompt anticoagulation therapy are the keys to a successful outcome.
Liver resections are demanding operations which can have life threatening complications although they are performed by experienced liver surgeons. The parameter “Blood Loss” has a central role in liver surgery, and different strategies to minimize it are a key to improve results. Moreover, recently, new technologies are applied in the field of liver surgery, having one goal: safer and easier liver operations. The aim of this paper is to review the different principal solutions to the problem of blood loss in hepatic surgery, focusing on technical aspects of new devices.
BackgroundThe prognosis of patients with liver metastases from gastric cancer (LMGC) is dismal, and little is known about prognostic factors in these patients; so justification for surgical resection is still controversial. Furthermore the results of chemotherapy for these patients are disappointing. The purpose of this study was to review recent outcomes of hepatectomy for LMGC and to determine the suitable candidates for surgery, assessing the surgical results and clinicopathologic features. Moreover we compare these results with those obtained with alternative treatments.
