Will partial splenic embolization followed by splenectomy increase intraoperative bleeding?

BACKGROUND Partial splenic embolization(PSE)has been suggested as an alternative to splenectomy in the treatment of hypersplenism.However,some patients may experience recurrence of hypersplenism after PSE and require splenectomy.Currently,there is a lack of evidence-based medical support regarding whether preoperative PSE followed by splenectomy can reduce the incidence of complications.AIM To investigate the safety and therapeutic efficacy of preoperative PSE followed by splenectomy in patients with cirrhosis and hypersplenism.METHODS Between January 2010 and December 2021,321 consecutive patients with cirrhosis and hypersplenism underwent splenectomy at our department.Based on whether PSE was performed prior to splenectomy,the patients were divided into two groups:PSE group(n=40)and non-PSE group(n=281).Patient characteristics,postoperative complications,and follow-up data were compared between groups.Propensity score matching(PSM)was conducted,and univariable and multivariable analyses were used to establish a nomogram predictive model for intraoperative bleeding(IB).The receiver operating characteristic curve,Hosmer-Lemeshow goodness-of-fit test,and decision curve analysis(DCA)were employed to evaluate the differentiation,calibration,and clinical performance of the model.RESULTS After PSM,the non-PSE group showed significant reductions in hospital stay,intraoperative blood loss,and operation time(all P=0.00).Multivariate analysis revealed that spleen length,portal vein diameter,splenic vein diameter,and history of PSE were independent predictive factors for IB.A nomogram predictive model of IB was constructed,and DCA demonstrated the clinical utility of this model.Both groups exhibited similar results in terms of overall survival during the follow-up period.CONCLUSION Preoperative PSE followed by splenectomy may increase the incidence of IB and a nomogram-based prediction model can predict the occurrence of IB.

Successful splenic artery embolization in a patient with Behçet’s syndrome-associated splenic rupture:A case report

BACKGROUND Splenic rupture associated with Behçet’s syndrome(BS)is extremely rare,and there is no consensus on its management.In this case report,a patient with BSassociated splenic rupture was successfully treated with splenic artery embolization(SAE)and had a good prognosis after the intervention.CASE SUMMARY The patient was admitted for pain in the left upper abdominal quadrant.He was diagnosed with splenic rupture.Multiple oral and genital aphthous ulcers were observed,and acne scars were found on his back.He had a 2-year history of BS diagnosis,with symptoms of oral and genital ulcers.At that time,he was treated with oral corticosteroids for 1 month,but the symptoms did not alleviate.He underwent SAE to treat the rupture.On the first day after SAE,the patient reported a complete resolution of abdominal pain and was discharged 5 d later.Three months after the intervention,a computed tomography examination showed that the splenic hematoma had formed a stable cystic effusion,suggesting a good prognosis.CONCLUSION SAE might be a good choice for BS-associated splenic rupture based on good surgical practice and material selection.

Balloon-occluded retrograde transvenous obliteration for treatment of gastric varices

Rupture of gastric varices(GVs)can be fatal.Balloon-occluded retrograde transvenous obliteration(BRTO),as known as retrograde sclerotherapy,has been widely adopted for treatment of GVs because of its effectiveness,ability to cure,and utility in emergency and prophylactic treatment.Simplifying the route of blood flow from GVs to the gastrorenal shunt is important for the successful BRTO.This review outlines BRTO indications and contraindications,describes basic BRTO procedures and modifications,compares BRTO with other GVs treatments,and discusses various combination therapies.Combined BRTO and partial splenic embolization may prevent exacerbation of esophageal varices and shows promise as a treatment option.

Expectations for partial splenic arterial embolization simultaneous transcatheter arterial chemoembolization for hepatocellular carcinoma

Hepatocellular carcinoma(HCC)is frequently complicated by cirrhosis,and it is not unusual for treatment options to be limited as a result of pancytopenia due to hypersplenism.Partial splenic embolization(PSE)has been performed for thrombocytopenia resulting from hypersplenism.However,the safety and effi cacy of concurrent transcatheter arterial chemoembolization(TACE)with PSE for HCC remain unclear.Thrombocytopenia has been improved,and treatment continued using concurrent PSE.In addition,the hepatic functional reserve could be maintained even after treatment for HCC.Concurrent TACE and PSE for HCC with thrombocytopenia can be expected to help maintain a hepatic reserve,and it may contribute to improving the prognosis of HCC.Hence,PSE could lead to an asplenic state.The appearance of Howell-Jolly bodies on a peripheral blood smear is reported useful for assessing splenic function.The appearance of Howell-Jolly bodies is associated with an increased risk for post-splenectomy sepsis/overwhelming post-splenectomy infection in patients with reduced splenic function.These bodies are frequently observed in peripheral erythrocytes after PSE,and when they are present,it is appropriate to administer the pneumococcal vaccine to prevent severe infection.The expectations for PSE combined with TACE for the treatment of HCC associated with cirrhosis are reviewed.

Acute pancreatitis associated left-sided portal hypertension with severe gastrointestinal bleeding treated by transcatheter splenic artery embolization:a case report and literature review

Left-sided portal hypertension(LSPH)followed by acute pancreatitis is a rare condition with most patients being asymptomatic.In cases where gastrointestinal(GI)bleeding is present,however,the condition is more complicated and the mortality is very high because of the difficulty in diagnosing and selecting optimal treatment.A successfully treated case with severe GI bleeding by transcatheter splenic artery embolization is reported in this article.The patient exhibited severe uncontrollable GI bleeding and was confirmed as gastric varices secondary to LSPH by enhanced computed tomography(CT)scan and CT-angiography.After embolization,the bleeding stopped and stabilized for the entire follow-up period without any severe complications.In conclusion,embolization of the splenic artery is a simple,safe,and effective method of controlling gastric variceal bleeding caused by LSPH in acute pancreatitis.
