Objective To evaluate the effect of laparoscopic splenectomy （LS） and open splenectomy （OS） forhypersplenism secondary to liver cirrhosis with portal hypertension. Methods Cochrane Central Register of Controlled Trials， Cochrane Database of Systematic Reviews， Medline， Embase， CINAHL， CBM， CNKI， VIP and WanFang database were searched for randomized control trials or retrospective studies related to the effect of LS and OS for hyper-splenism secondary to liver cirrhosis with portal hypertension. Then studies were screened according to the inclusion and exclusion criterias， data were collected， and quality of studies were evaluated. RevMan 5.1.0 software was used for meta-analysis. Results Seventeen retrospective studies and one randomized control trial were enrolled. The results of meta analysis showed that， the estimated blood loss， postoperative hospital stay， rate of postoperative complication， and WBC level on 1 day after operation of LS group were significantly lower or shorter than those of OS group （P＜0.05）. However， there were no significant differences on operative time， WBC level on 7 days after operation， postoperative platelets （1 day and 7 days after operation）， alanine aminotransferase （1 day and 7 days after operation）， and total bilirubin （1 day and 7 days after operation） between LS group and OS group （P＞0.05）. Conclusions LS may be more effective to reduce blood loss， postoperative hospital stay， and rate of postoperative complication in patients with hypersplenism secondary to liver cirrhosis with portal hypertension in comparison to OS. However， the effectiveness of LS on liver function is not clear.
ObjectiveTo evaluate the operative technique and clinical efficacy of laparoscopic splenectomy (LS) combined with esophagogastric devascularization in treatment of portal hypertension induced by liver cirrhosis. MethodsTwelve cases with esophageal and gastric varices induced by portal hypertension and liver cirrhosis were treated by the LS combined with esophagogastric devascularization in our department from March 2009 to August 2010, which clinical data were analyzed and summarized retrospectively. ResultsThe splenic artery was ligated before the treatment of splenic pedicle in 12 cases, LS combined with pericardial devascularization was successfully performed in 10 cases, 7 cases of which were treated by the level two transection method of splenic pedicle, and 2 cases were converted to open surgery due to intraoperative bleeding. In 10 cases, the operative time was 180-300 min (average 210 min), and intraoperative blood loss was 200-1 000 ml (average 480 ml). The postoperative hospital stay was 8-15 d (average 9 d)， the postoperative complications included plural effusion （lt;300 ml） in 2 cases， mild ascites （lt;300 ml） in 2 cases, and mild pancreatic leakage in 1 case， but all were cured eventually， and no mortality occurred. Followup was conducted in 12 patients for 4 to 20 months (average 7 months), and no rebleeding occurred. ConclusionsLS combined with pericardial devascularization is relatively safe and effective methods in treatment of portal hypertension induced by liver cirrhosis. The keys to success include ligation of splenic artery, and the use of harmonic scalpel combined with ligasure to treat splenic pedicle.
Objective To investigate safety, feasibility, and future direction of laparoscopic splenectomy. Method The latest progress and new achievements of laparoscopic splenectomy in the world were analyzed and summarized. Results At present, the laparoscopic splenectomy mainly included the completely laparoscopic splenectomy, hand assisted laparoscopic splenectomy, gasless laparoscopic splenectomy, single hole laparoscopic splenectomy, or robot assisted laparoscopic splenectomy. The completely laparoscopic total splenectomy had become the most common surgical procedure in the clinical treatment due to the reliable curative effect, less injury, and rapid recovery, the partial splenectomy was one of the precise treatments for the benign splenic lesions. The hand assisted laparoscopic splenectomy was widely used in the giant spleen, it could reduce the exposure difficulty, effectively deal with the intraoperative hemorrhage, and reduce the risk of surgery. The robot assisted laparoscopic splenectomy was one of the minimally invasive operations, the system with three-dimensional high definition vision and flexible robotic arm overcame the limitations of traditional laparoscopic two-dimensional display, could precisely complete the operation and achieve the accurate treatment. Conclusions Laparoscopic splenectomy has some advantages of less operative injury, less pain, and rapid recovery, it’s safety and feasibility have been proved. We should strictly grasp indications and contraindications for laparoscopic splenectomy, appropriate surgical methods should be selected for specific splenic diseases to achieve the best curative effect. Remote control and precision operation will be a direction of development in future.
ObjectiveTo summarize the pathogenesis, epidemiology, and risk factors of portal vein thrombosis after splenectomy, and combined with the latest advances in clinical prevention, diagnosis, and treatment of portal vein thrombosis after splenectomy, so as to provide some references for clinical prevention and treatment in the future.MethodLiteratures on portal vein thrombosis after splenectomy were collected and reviewed.ResultsThe incidence of portal vein thrombosis after splenectomy was high and its occurrence was the result of multiple factors. It was mainly related to the change of splenic venous blood flow mechanics after splenectomy. In terms of diagnosis, enhanced CT scan was the first choice. Currently, there was no consensus on treatment options, which mainly focused on individualized treatment and emphasized that preventive anticoagulant use of low-molecular-weight heparin may reduce the risk of portal vein thrombosis.ConclusionThe concept of tertiary prevention of portal vein thrombosis after splenectomy should be established, and individualized treatment should be adopted in combination with the patient’s condition.
Objective To evaluate the efficacy of the subtotal splenectomy versus total splenectomy with gastroesophageal devascularization for patients of hepatic cirrhosis and portal hypertension. Methods We searched the Cochrane Library (Issue 2, 2008), MEDLINE (1966 to August, 2008), EMbase (1966 to August, 2008), the China Biological Medicine Database (1978 to August, 2008), Chinese Sci-tech Periodical Full-text Database (1989 to August, 2008) and Chinese Periodical Full-text Database (1994 to August, 2008), as well as hand-searched several related journals and conference proceedings for the randomized controlled trials involving the comparison of the efficacy of the subtotal splenectomy with the total splenectomy for the patients of the hepatic cirrhosis and portal hypertension. Results Three studies involving 136 patients were identified. The results of two studies indicated that both of the subtotal splenectomy increased less the peripheral platelet count and there was a statistically significant difference between the two groups [WMD= – 39.27, 95%CI (– 62.57, – 15.97)]. Two studies indicated that the serum tuftsin level was increased significantly after the subtotal splenectomy [WMD= 165.28, 95%CI (159.36, 171.21)]. One study indicated that both of the subtotal splenectomy and total splenectomy with gastroesophageal devascularization increased the peripheral white blood cell count and there was statistical difference between the two groups [WMD= – 0.93, 95%CI (– 1.52, – 0.34)]. There was no statistical difference in serum IgA level between the two groups. One study indicated the average fever time after the total splenectomy was longer than the subtotal splenectomy; there was statistical differences in 5 years survival rate between the two groups (Plt;0.05). Conclusions After the subtotal splenectomy the hypersplenism of patients suffered from hepatic cirrhosis and portal hypertension was corrected obviously and the blood cells were increased smoothly so that high blood viscosity was prevented and occurrence of the thrombotic diseases was decreased. And the immune system reserve functions of the patients with hepatic cirrhosis and portal hypertension were maintained. More randomized controlled trials, with large sample sizes, may lead to more accurate results.
ObjectiveTo investigate the safety and feasibility of the treatment of laparoscopic splenectomy for patients with traumatic splenic rupture. MethodsBetween October 2006 and October 2009, 48 cases of traumatic splenic rupture underwent laparoscopic splenectomy were analyzed in this hospital. According to the differrent styles of splenic stalk, different operative methods were taken， including titanic clipping in 12 cases， titanic clipping combining silk suture ligation in 8 cases， snare combining titanic clipping in 10 cases， LigaSure in 8 cases， and EndoGIA in 8 cases. ResultsLaparoscopic splenectomy was successfully completed in 32 cases; Handassisted laparoscopic splenectomy was applied in 14 cases, and 2 cases were converted to laparotomy because of tight spleen adhesion with surrounding tissues and bleeding rupture of the short gastric vessels. The operation time was 120－170 min with an average 140 min; the estimated intraoperative amount of blood loss was 300－1 200 ml with an average 800 ml. No postoperative complication occurred such as gastric fistula, pancreatic fistula or hemorrhage. Conclusion According to the differrent styles of splenic stalk, individual operative method can improve mission success rate in the laparoscopic splenectomy in traumatic splenic rupture.
Pancreatic sinistral portal hypertension (PSPH) is a clinical syndrome resulting from pancreatic disease that blocks splenic vein return, which includes acute and chronic pancreatitis, pancreatic tumors, and iatrogenic factors related to pancreatic surgery. Most PSPH patients present with isolated gastric varices, splenomegaly and hypersplenism, with normal liver function, and upper gastrointestinal bleeding caused by varices in the fundus of the stomach is the most serious clinical manifestation. The treatment of PSPH can be divided into the treatment of portal hypertension in the spleen and stomach region, including close follow-up, medication, endoscopic therapy, splenic artery embolization and splenectomy, etc. The primary diseases of pancreas are mainly treated for acute pancreatitis, chronic pancreatitis and pancreatic tumor. In particular, PSPH related to pancreatic surgery should be concerned.
Objective To summarize the effect of the splenectomy in patients with portal hypertension on the occurrence and recurrence of hepatocellular carcinoma. Methods The related literatures about the splenectomy in patients with hepatocirrhosis combined with portal hypertension or patients with hepatocellular carcinoma combined with portal hypertension in recent years were reviewed. Results At present, most academics considered that, for patients with hepatocirrhosis combined with portal hypertension, splenectomy could reduce the occurrence of hepatocellular carcinoma. For patients with hepatocellular carcinoma combined with portal hypertension, splenectomy+hepatectomy didn’t increase the perioperative mortality, and it could reduce the recurrence rate of hepatocellular carcinoma. Conclusion Splenectomy for patients with portal hypertension is safe, and it can inhibit the occurrence and progress of hepatocellular carcinoma, however, the specific mechanism remain needs further study.
Compared with open surgery, laparoscopic radical resection of the body and tail pancreatic cancer is gradually being accepted due to its shorter hospital stay, reduced intraoperative blood loss, and comparable perioperative and oncological prognosis. The proposal of radical antegrade modular pancreatosplenectomy (RAMPS) has established a standardized approach for resection scope and lymph node dissection in pancreatic body and tail cancers. Studies have confirmed that RAMPS surgery can achieve a higher N1 station lymph node dissection, R0 margin ratio, and satisfactory patient survival rates. Furthermore, RAMPS has demonstrated oncological advantages in terms of postoperative local control. Laparoscopic RAMPS (LRAMPS) has been shown to be technically feasible and to yield long-term oncologic outcomes comparable to open RAMPS. An increasing number of studies have evaluated LRAMPS as the standard surgical modality for resectable body and tail pancreatic cancers. This article discusses the main points and challenges of LRAMPS surgery, and presents some personal experiences.
Objective To investigate the effectiveness and safety of low molecular weight heparin combined with aspirin for perioperative prophylactic anticoagulation in patients with lower extremity fracture after splenectomy. MethodsThe clinical data of 50 patients with splenic rupture combined with lower extremity fracture between January 2009 and June 2022 were retrospectively analyzed. All patients were given enoxaparin sodium at 48 hours after splenectomy, and stopped at 24 hours before fracture surgery. After fracture surgery, the patients were divided into aspirin group (group A, 15 cases), low molecular weight heparin group (group B, 16 cases), and low molecular weight heparin combined with aspirin group (group C, 19 cases) according to different anticoagulation regimens. The treatment course was 28 days. There was no significant difference in gender, age, body mass index, cause of injury, fracture site, time from injury to operation, complications, and other general data between groups (P>0.05). The occurrence of venous thromboembolism (VTE) was observed; hemoglobin (Hb), platelet (PLT), D-D dimer, and fibrinogen degradation product (FDP) were recorded before operation and at 1, 3, and 7 days after operation, and the effect of anticoagulation regimen on coagulation function was observed. The incidences of wound complications and bleeding related complications were recorded, and the total perioperative blood loss, hidden blood loss, and overt blood loss were calculated. Results The incidences of VTE in groups A, B, and C were 13.33% (2/15), 12.50% (2/16), and 5.26% (1/19), respectively, and there was no significant difference between groups (χ2=0.770, P=0.680). There was no portal vein thrombosis and no VTE-related death in the 3 groups. There was no significant difference in the levels of Hb, PLT, D-D dimer, and FDP between groups before and after operation (P>0.05); and there was no significant difference in total perioperative blood loss, hidden blood loss, and overt blood loss between groups (P>0.05). No local skin necrosis was found in all patients. In group A, 1 case occurred redness and swelling of incision; in group B, 1 case had incision discharge, redness, and swelling, and 1 case had fat liquefaction; in group C, 1 case had repeated incision exudation accompanied by local tissue redness and swelling, and 1 case had local hematoma. The incidences of adverse incision in groups A, B, and C were 6.66% (1/15), 12.50% (2/16), and 11.76% (2/19), respectively, with no significant difference (χ2=0.302, P=0.860). There were 4 cases of bleeding related complications, including 1 case of incision ecchymosis in groups A and B respectively, with the incidence of 6.66% and 6.25%, respectively; there was 1 case of incision hematoma and 1 case of bleeding in group C, with the incidence of 11.76%; showing no significant difference in the incidence of bleeding related complications between groups (χ2=0.268, P=0.875). Conclusion Perioperative combined use of low molecular weight heparin and aspirin for prevention of anticoagulation in patients with splenic rupture and lower extremity fracture can effectively prevent the occurrence of VTE without increasing the incidence of complications, which is an effective and safe treatment method. However, whether the incidence of VTE can be reduced needs to be further studied by expanding the sample size.
