The role of the ultrasonically activated shears and vascular cutting stapler in hepatic resection

Hemorrhage and liver failure are the two greatest concerns for patients undergoing major liver resection. Inflow occlusion (Pringle maneuver) is often used to minimize blood loss, but hepatic ischemia results in an increased risk of postoperative hepatic dysfunction. We report our experience with the Harmonic Scalpel ultrasonically activated shears (UAS; Ethicon Endo-Surgery, Cincinnati, OH) and a vascular stapler for hepatic resection as technological advances that aid in minimizing blood loss and thereby reduce the need for inflow occlusion. We retrospectively reviewed liver resections performed from September 1997 through July 1998, in which the UAS and articulating vascular endoscopic linear cutting stapler were used. The vascular stapler was used to divide the appropriate portal vein branch and hepatic vein(s) before parenchymal transection. Parenchymal dissection was performed with UAS to a depth of approximately 2 to 3 cm, and the remainder of the liver parenchyma was divided by a clamp crush and clip and suture ligate technique. Patients underwent segmental resection (n = 12), lobectomy (n = 13), or extended lobectomy (n = 11). Resection was performed for metastatic disease, primary liver tumors, or benign disease in 21, 8, and 7 patients, respectively. A Pringle maneuver was performed in 7 of 36 patients (mean clamp time, 8 minutes). The median required intraoperative blood transfusion was 0 units of packed red blood cells. Major and minor complications occurred in 12 and 3 patients, respectively. Two deaths were related to pneumonia and abdominal infection. The vascular stapler safely and securely divides portal vein branches and hepatic veins. The UAS initiates parenchymal transection with minimal blood loss. These two technologies facilitate the surgeon's aim of liver resection without blood transfusion or Pringle maneuver.

Prospective evaluation of Pringle maneuver in hepatectomy for liver tumors by a randomized study.

OBJECTIVE: To evaluate whether vascular inflow occlusion by the Pringle maneuver during hepatectomy can be safe and effective in reducing blood loss. SUMMARY BACKGROUND DATA: Hepatectomy can be performed with a low mortality rate, but massive hemorrhage during surgery remains a potentially lethal problem. The Pringle maneuver is traditionally used during hepatectomy to reduce blood loss, but there is a potential harmful effect on the metabolic function of hepatocytes. There has been no prospective randomized study to determine whether the Pringle maneuver can decrease blood loss during hepatectomy, improve outcome, or affect the metabolism of hepatocytes. METHODS: From July 1995 to February 1997, we studied 100 consecutive patients who underwent hepatectomy for liver tumors. The patients were randomly assigned to liver transection under intermittent Pringle maneuver of 20 minutes and a 5-minute clamp-free interval (n = 50), or liver transection without the Pringle maneuver (n = 50). The surface area of liver transection was measured and blood loss during transection per square centimeter of transection area was calculated. Routine liver biochemistry, arterial ketone body ratio (AKBR), and the indocyanine green (ICG) clearance test were done. RESULTS: The two groups were comparable in terms of preoperative liver function and in the proportion of patients having major hepatectomy. The Pringle maneuver resulted in less blood loss per square centimeter of transection area (12 mL/cm2 vs. 22 mL/cm2, p = 0.0001), a shorter transection time per square centimeter of transection area (2 min/cm2 vs. 2.8 min/cm2, p = 0.016), a significantly higher AKBR in the first 2 hours after hepatectomy, lower serum bilirubin levels in the early postoperative period, and, in cirrhotic patients, higher serum transferrin levels on postoperative days 1 and 8. The complication rate, the hospital mortality rate, and the ICG retention at 15 minutes on postoperative day 8 were equal for the two groups.CONCLUSION: Performing the Pringle maneuver during liver transection resulted in less blood loss and better preservation of liver function in the early postoperative period. This is probably because there was less hemodynamic disturbance induced by the bleeding.     

A prospective randomized controlled trial to compare Pringle maneuver, hemihepatic vascular inflow occlusion, and main portal vein inflow occlusion in partial hepatectomy

Background

Blood loss during liver resection and the need for perioperative blood transfusions have negative impact on perioperative morbidity, mortality, and long-term outcomes.

Methods

A randomized controlled trial was performed on patients undergoing liver resection comparing hemihepatic vascular inflow occlusion, main portal vein inflow occlusion, and Pringle maneuver. The primary endpoints were intraoperative blood loss and postoperative liver injury. The secondary outcomes were operating time, morbidity, and mortality.

Results

A total of 180 patients were randomized into 3 groups according to the technique used for inflow occlusion during hepatectomy: the hemihepatic vascular inflow occlusion group (n = 60), the main portal vein inflow occlusion group (n = 60), and the Pringle maneuver group (n = 60). Only 1 patient in the hemihepatic vascular occlusion group required conversion to the Pringle maneuver because of technical difficulty. The Pringle maneuver group showed a significantly shorter operating time. There were no significant differences between the 3 groups in intraoperative blood loss and perioperative mortality. The degree of postoperative liver injury and complication rates were significantly higher in the Pringle maneuver group, resulting in a significantly longer hospital stay.

Conclusions

All 3 vascular inflow occlusion techniques were safe and efficacious in reducing blood loss. Patients subjected to hemihepatic vascular inflow occlusion, or main portal vein inflow occlusion responded better than those with Pringle maneuver in terms of earlier recovery of postoperative liver function. As hemihepatic vascular inflow occlusion was technically easier than main portal vein inflow occlusion, it is recommended.

Tolerance of the liver to intermittent pringle maneuver in hepatectomy for liver tumors.

BACKGROUND: Hepatectomy can be performed with a low mortality rate, but massive hemorrhage during the operation remains a potentially lethal problem. The Pringle maneuver is traditionally used during hepatectomy to reduce blood loss, but the effect on the metabolic function of hepatocytes is potentially harmful. Although our randomized study showed that an intermittent Pringle maneuver is safe and effective during hepatectomy, the upper limit of the duration of the Pringle maneuver is not known. HYPOTHESIS: The liver can tolerate intermittent Pringle maneuver if the duration is not excessive. DESIGN: From July 20, 1995, to November 25, 1997, 112 patients underwent hepatectomy for liver tumors. The data of 50 patients who had hepatectomy without the Pringle maneuver were compared with those of 62 patients who had a liver transection using a Pringle maneuver for 20 minutes and a 5-minute clamp-free interval. The data were collected prospectively. MAIN OUTCOME MEASURES: The surface area of liver transection was measured, and blood loss during liver transection per centimeter square of transection area was calculated. Routine liver biochemical tests, arterial ketone body ratio (AKBR), and plasma cytokine-interleukin (IL) 1alpha, 1beta, 2, and 6, and tumor necrosis factor alpha--levels were measured before and after the operation. The morbidity and hospital mortality rates were also compared among the patients with different ischemic durations and those without an intermittent Pringle maneuver. SETTING: Tertiary referral center. RESULTS: The cutoff point of accumulated ischemic time that induced substantial liver damage, as shown by the postoperative recovery rate of the AKBR, was found to be 120 minutes. Compared with the control group, the patients whose accumulated ischemic time was shorter than 120 minutes had less blood loss related to transection area (10 mL/cm2 vs 22 mL/cm2; P<.001), less blood transfused (0 L vs 0.6 L; P = .004), a shorter transection time related to transection area (2.0 min/cm2 vs 2.8 min/ cm2; P = .002), a significantly higher AKBR in the first 2 hours after liver transection, an equal recovery rate of the AKBR, and a comparable increase of the plasma level of IL-6 postoperatively. For the patients whose accumulated ischemic time was longer than 120 minutes, blood loss from the transection area was less than for the control group (14 mL/cm2 vs 22 mL/cm2; P<.05), but the transection time related to the transection area and the blood transfusion volume did not differ from those of the control group. Furthermore, they had a significantly lower recovery rate of the AKBR and higher plasma levels of IL-6 postoperatively than the control group.

Laparoscopic intrahepatic Glissonian approach for right hepatectomy is safe,simple, and reproducible

Background Hemorrhage from portal and hepatic veins is a major concern with laparoscopic right hepatectomy (LRH). The standard hilar approach is dissection of the portal pedicle outside the liver parenchyma with separate transection of the right hepatic artery, portal vein, and bile duct [1–5, 7, 9]. Variations in anatomy can hamper vascular and biliary control. The intrahepatic Glissonian access avoids these risks by en masse ligation of the portal structures without dissection for each separately [6, 8]. This technique was performed laparoscopically for the last 2 among 10 LRHs, and the results are presented. Methods Total LRH was performed under ultrasound assistance for two patients with malignancy. After lymph node sampling at the hepatoduodenal ligament, dissection was started with the incision of liver parenchyma posterior and anterior to the hilum, then continued outside the portal pedicle bifurcation toward the right and left sheaths. An endoscopic vascular stapling device was placed to transect the right portal pedicle en masse under direct laparoscopic vision and cholangiography guidance. Parenchymal transection and vascular control of the right hepatic vein was accomplished with harmonic scalpel, cavitron ultrasonic aspirator, bipolar diathermy, clips, and endoscopic stapling device, as appropriate. No Pringle’s maneuver was used. The specimen was extracted through a suprapubic incision using an endobag. Results The operative times for the two patients were, respectively, 180 and 240 min. No blood loss occurred during the intrahepatic Glissonian dissection. Intraoperative blood loss (from the right hepatic vein) of 700 and 800 ml, respectively, was controlled laparoscopically. The postoperative periods were uneventful, with discharge, respectively, on days 6 and 7. The surgical resection margins were free of tumor. Conclusions The laparoscopic intrahepatic Glissonian approach used for right hepatectomy is safe, simple, and reproducible. It facilitates the hepatic hilar dissection with minimal operative risk. Further implementation of this technique is encouraged to improve the outcome for patients undergoing laparoscopic liver resection.
