Objective To investigate the technique and feasibility of hepatic pedicle vascular control in laparoscopic hepatectomy. Methods From May 2005 to June 2011, 95 cases of hepatectomies were performed by laparoscopy in the Department of Minimally Invasive Surgery, The First Affiliated Hospital, Guangxi Medical University.The characteristics of these cases were analyzed. Results Left lateral segmentectomy were required in 21 patients, left hepatectomy in 13 patients, right hepatectomy in 4 patients, segmentectomy in 17 patients, tumor resection in 24 patients,hemangioma resection in 5 patients, and conversions to laparotomy in 11 patients. The intermittent Pringle maneuver were performed in 39 patients. The mean vascular clamping time in Pringle maneuver was （30.84±9.51） min. The selective vascular control of inflow were performed in 56 patients， the technique included intrahepatic Glisson approach in 14 patients and controlling hepatic artery and portal vein separately in 42 patients. Pre-parenchymal transection control of hepatic outflow were performed in 12 patients, included the left hepatic vein were controlled by suturing or separating in 11 patients and right hepatic vein was controlled by separating in 1 patient. Others were controlled intraparenchymally during transection. The mean operative time was （236.80±95.97） min，mean operative blood loss was（ 551.55±497.41） ml， concentrate red blood cells transfusion volume was（ 2.60±2.23） U， and plasma transfusion volume was （211.90±179.29） ml. The postoperative complications included bleeding in 4 patients, pleural effusion in 4 patients, pneumonia in 3 patients, ascites in 7 patients, and biliary fistula in 2 patients, and dead in 1 patient. The mean hospitalization time was（ 12.47±4.18） days. At the deadline（ February 2012）, 72 cases with liver cancer were followup. The follow-up time ranged from 5 to 81 months and the mean time was（ 24.14±16.62） months， where survival rate was 68.4%（ 54/79） of 1-year and 21.5%（ 17/79） of 3-year. Conclusions The application of hepatic pedicle vascular control in laparoscopic hepatectomy is feasible.
Objective To evaluate different clinical effects of three inflow occlusion methods in hepatectomy including pringle maneuver （Pringle group），selective portal venous exclusion （SPVE group）， and Glissonean pedicle exclusion （SGSE group）. Methods The clinical data of patients underwent the liver resection with the above liver inflow occlusion methods were retrospectively analyzed. The operation time， inflow occlusion time， amount of intraop-erative blood loss， transfusion rate， and postoperative hepatic function and complication rate were compared for each group. Results There were not significant difference of preoperative conditions，operation time， inflow occlusion time，tumor character， postoperative liver function， hospital time，and ICU time （P＞0.05）. The amount of intraoperative blood loss and rate of blood transfusion of SGSE group were significantly less （lower） than those Pringle group and SPVEgroup （P＜0.05）. In addition to the first day after operation， the AST and ALT at other time point of SPVE group and SGSE group were improved than that Pringle group （P＜0.05）， while TBIL at the third and fifth day after operation ofPringle group were improved （P＜0.05）. The complication rates of SPVE group and SGSE group were significantly lowerthan that of Pringle group （P＜0.05）. Conclusions In the similar operatin time and inflow occlusion time，Glissonean pedicle exclusion method can control the intraoperative blood loss and blood transfusion better，and can promote the patientrecovery. Besides， the inflow occlusion methods should be selected based on the practical condition of patients.
【Abstract】 ObjectiveTo review the advances in techniques of hepatic blood occlusion in hepatectomy. Methods The related literatures were reviewed and analysed. ResultsThere were many techniques of hepatic blood occlusion. The most frequently used and studied techniques were hemihepatic vascular occlusion and intermittent hepatic inflow occlusion. Hepatic vascular exclusion was employed when hepatic veins and/or vena cava would be damaged. Total vascular exclusion and other techniques were rarely used. Conclusion To reduce blood loss in hepatectomy and make patient safe, based on the situation of the patient, the technique should be ingeniously selected.
ObjectiveTo investigate the correlation between perioperative blood transfusion and hepatic postoperative infection. MethodsOne hundred and thirty patients undergoing hepatic operation were analyzed retrospectively on the relation of perioperative blood transfusion with postoperative infective morbidity and mortality in the period 1989-1999. The patients were divided into blood transfused group and nontransfused group. The major or minor hepatectomy was performed in 53 patients with hepatic malignancy and benign diseases. ResultsIn the blood transfused group, the infective morbidity and perioperative mortality rate was 38.5% and 16.7% respectively, significantly higher than those in nontransfused group (11.5% and 3.8% respectively), P＜0.05. The total lymphocyte count was lower in transfused group than that in nontransfused group. The postoperative antibiotics used time and length of hospital stay were (9.7±4.2) days and (18.7±13.1) days respectively in transfused group than those in nontransfused group (5.3±2.3) days and (12.7±5.2) days respectively. ConclusionThe results suggest that hepatic postoperative infective morbidity and mortality are related with perioperative blood transfusion. Any strategy to reduce blood loss in liver surgery and decrease blood transfusion would be helpful to lower postoperative infective morbidity.
目的探讨肝血管瘤切除术中血流阻断方法的选择。方法回顾性分析我院收治的19例肝血管瘤患者的手术方式。结果全组均行手术切除，术中出血50～1 500 ml（平均312 ml）。 术中根据血管瘤所在位置选择不同肝血流阻断方法，其中行半肝血流阻断4例，运用Glisson蒂横断式肝切除术或其分段原理阻断Glisson系统分支6例，间断阻断第一肝门7例，预置肝上、下下腔静脉和第一肝门阻断带并间断阻断第一肝门2例。 术后5例并发右侧胸腔积液，均经保守治疗后好转，手术并发症发生率为26.3%（5/19）。 术后住院7～41 d（平均16.9 d），均治愈出院。12例患者获随访，随访0.3～2年（平均1.1年），术前有症状的8例患者症状均消失，无复发，1例残留肝内血管瘤（直径lt;2 cm）。结论肝血管瘤患者肝切除术中的入肝血流阻断应强调个体化，根据肿瘤位置及大小选择不同的阻断方法，使患者术中出血少，术后恢复快。
ObjectiveTo investigate the clinical application effect of descending hilar plate technology in laparoscopic heminephrectomy for intrahepatic bile duct calculus.MethodsThe clinical data of 40 patients with intrahepatic bile duct calculus who underwent laparoscopic heminephrectomy in our hospital from January 2015 to December 2019 were retrospectively analyzed. The patients were grouped according to different surgical procedures, 21 patients with Pringle method of total hepatic vascular exclusion were classified in the control group, and 19 patients with descending hilar plate technology of blood occlusion technology were classified in the observation group. The operation time, intraoperative bleeding volume, postoperative hospital stays, liver function recovery, and postoperative complications were compared between the two groups.ResultsThere was no statistically significant difference between the two groups in the intraoperative bleeding volume and operation time (P>0.05), but the postoperative hospital stays in the observation group shortened (P=0.025). The changes on the ALT, TB, and AST in the observation group was obvious than those of the control group (P<0.05). There was no statistically significant incidence between the two groups in the total incidence of complications (P=0.128).ConclusionsCompared with Pringle method of total hepatic vascular exclusion, descending hilar plate technology in laparoscopic heminephrectomy can fully expose the Glisson pedicles of the left and right livers, and it is convenient to implement hemihepatic blood flow occlusion. It has less damage to healthy side of the liver and quicker liver function recovery, and it can reduce postoperative complications and shorten postoperative hospital stay.
ObjectiveTo systematically review the efficacy and safety of hemihepatic blood flow occlusion versus Pringle's maneuver during hepatectomy. MethodsWe electronically searched The Cochrane Library (Issue 8, 2013), PubMed, EMbase, CBM, CNKI, VIP and WanFang Data for randomized controlled trials (RCTs) about hemihepatic blood flow occlusion versus Pringle's maneuver during hepatectomy. The duration of search was from the inception of the databases to August 2013. Meanwhile, references of the included studies were also retrieved. After literature selection, data extraction and quality assessment conducted by two reviewers independently, meta-analysis was conducted using RevMan 5.2 software. ResultsSeven studies involving 624 patients were finally included. The results of meta-analysis showed that: a) for safety, Pringle's maneuver was shorter than hemihepatic blood flow occlusion in operation time (SMD=0.34, 95%CI 0.02 to 0.66, P=0.04). But they were alike in intraoperative blood loss, transfusion requirements, hospitalization time, and complications. b) For effectiveness, Pringle's maneuver was lower than hemihepatic blood flow occlusion in the levels of 3rd day ALT (SMD=-0.71, 95%CI-1.28 to-0.14, P=0.02), 7th day ALT (SMD=-1.73, 95%CI-2.85 to-0.62, P=0.002), 1st day AST (SMD=-0.74, 95%CI-1.38 to-0.09, P=0.03), 7th day AST (SMD=-0.99, 95%CI-1.26 to-0.71, P < 0.000 01), 3rd day TBIL (SMD=-0.34, 95%CI-0.57 to-0.10, P=0.005), and 7th day TBIL (SMD=-0.52, 95%CI-1.02 to-0.01, P=0.04). ConclusionCompared to the Pringle's maneuver, hemihepatic blood flow occlusion during hepatectomy could promote the recovery of liver function. However, the number of the included RCTs in the review is small and the quality is low, some of the main information is not reported and the information for analysis lacks. Therefore, the aforementioned conclusion needs to be verified by conducting more large-scale, multicenter and high-quality RCTs.
目的探讨保留肝动脉血供的肝血流阻断对肝切除术失血量和肝功能的影响。 方法回顾性分析了2007年9月至2012年12月期间上海交通大学医学院附属第三人民医院118例行肝切除术患者的临床资料，其中68例行保留肝动脉血供的肝血流阻断（保留组），50例采用Pringl法行肝门阻断（阻断组），比较2组的手术失血量、接受输血病例的比例、手术并发症以及术后肝功能恢复情况。 结果全组无围手术期死亡病例。保留组患者的平均手术时间、术中失血量、接受输血患者的比例、术后肠道功能恢复时间以及术后并发症发生率与阻断组相比差异均无统计学意义（P＞0.05）；术后第1天及第5天，谷丙转氨酶及谷草转氨酶水平保留组明显低于阻断组（P＜0.05）。 结论保留肝动脉血供的肝血流阻断法能有效控制肝断面出血，明显保护了肝脏功能，且并未延长手术时间。
