Efficacy and safety of Chinese herbal medicine in treating postcholecystectomy diarrhea: A systematic review and meta-analysis.

BACKGROUND: Postcholecystectomy diarrhea (PCD) is among the most distressing and well-known clinical complications of cholecystectomy. Despite various available treatment options, clinical outcomes are greatly limited by unclear pathophysiological mechanisms. Chinese herbal medicine (CHM) is widely used as a complementary and alternative therapy for the treatment of functional diarrhea. Thus, we conducted a meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy and safety of CHM for the treatment of PCD. METHODS: Electronic database searches were conducted using the Cochrane Library, PubMed, Web of Science, Embase, Wanfang Data, China National Knowledge Infrastructure, and the Chinese Scientific Journal Database. All RCTs on CHMs for managing patients with PCD were included. The meta-analysis was performed using RevMan 5.4 software. RESULTS: The present meta-analysis included 14 RCTs published between 2009 and 2021 in China. The primary findings indicated that CHM had a higher total efficacy and cure rate as a monotherapy for PCD (P < .00001). Two trials reported the scores of the main symptoms with statistically significant differences in stool nature (P < .00001), defecation frequency (P = .002), and abdominal pain and bloating (P < .00001). In addition, CHM reduced CD3+ and CD4+ levels more effectively in terms of T lymphocyte subset determination (P < .00001). The main symptoms of PCD in traditional Chinese medicine (TCM) are splenic deficiency and liver stagnation. All treatments were used to strengthen the spleen and (or) soothing the liver. CONCLUSION: CHM had a favorable effect on PCD. No adverse events were observed. Larger, high-quality RCTs are warranted to draw definitive conclusions and standardize treatment protocols.

Effect of neoadjuvant chemotherapy on survival in patients with T1 high-grade non-muscle-invasive bladder cancer who underwent radical cystectomy.

Patients with non-muscle-invasive bladder cancer (NMIBC) who are at high and very high risk of disease progression are recommended for radical cystectomy (RC). However, the impact of neoadjuvant chemotherapy (NAC) on survival outcomes in NMIBC patients undergoing RC remains unclear. Patients diagnosed with T1 high-grade NMIBC who underwent RC were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Overall survival (OS) was assessed using the Kaplan-Meier technique, and multivariable Cox regression analysis was conducted to determine the independent factors of OS. A total of 1268 T1 high-grade NMIBC patients who underwent RC between 2004 and 2015 were included in the study. NAC was administered to 76 (6.0%) patients. At a median follow-up of 75 months, there was no significant difference in the OS between the NAC and non-NAC groups (HR = 0.89, 95% CI 0.61-1.30, P = .539). However, in the multivariate Cox regression model, NAC demonstrated a more pronounced improvement in OS approaching statistical significance (HR = 0.7, 95% CI 0.47-1.05, P = .088). Subgroup analysis revealed a survival benefit of NAC in patients with lymph node metastasis. In summary, the results of this study suggest that NAC has the potential to confer a survival advantage in patients diagnosed with T1 high-grade NMIBC who undergo RC, but additional studies are needed. Nonetheless, the survival benefits of NAC in patients with lymph node involvement are apparent.

Repeat hepatectomy for pediatric recurrent chemotherapy-resistant hepatoblastoma: a report of 18 cases.

BACKGROUND AND AIMS: Repeat hepatectomy for adult recurrent hepatocellular carcinoma significantly prolongs the overall survival, but repeat hepatectomy for pediatric recurrent hepatoblastoma (HB) is rarely reported, and the outcomes are warranted to be investigated. METHODS: All patients between May 2015 and December 2020 with recurrent HB after intended surgical cure were retrospectively evaluated. Clinicopathologic features, surgical details and outcomes were analyzed during a median following-up of 24 months after repeat hepatectomy. Survival analysis was performed using the Kaplan-Meier estimate. RESULTS: A total of 18 patients of recurrent HB undergoing repeat hepatectomy with radical cure intention were included. There were 11 males and 7 females. The median age was 29 months (range 5-87 months) at first hepatectomy, and the median time to the recurrence from the first hepatectomy was 7 months. The operating time of the repeat hepatectomy was 5.0 h (range 3.5-9.0 h) and the mean blood loss was 592 ml (range 50-3200 ml). Radical resection (R0) was achieved in 12 patients (66.7%), with a postoperative hospital stay of 7.9 ± 1.8 days. No serious postoperative complications or mortality occurred. The overall survival (OS) rate was 55.6% (10/18) and the event-free survival (EFS) rate was 33.3% (6/18). Those with no lung metastases, not high-risk stratification, and achieving R0 hepatectomy, anatomic hepatectomy had longer OS rate (all P < 0.05) after repeat hepatectomy. Two of three patients with re-recurrence HB undergoing salvage liver transplantation were alive with a tumor-free survival. CONCLUSIONS: Repeat hepatectomy for recurrent HB can be carried out safely. However, only a highly selected subgroup of patients might actually benefit from this procedure.

Robotic surgery twice performed in the treatment of hilar cholangiocarcinoma with deep jaundice: delayed right hemihepatectomy following the right-hepatic vascular control.

OBJECTIVE: To explore and find a new method to treat hilar cholangiocarcinoma with deep jaundice assisted by Da Vinci robot. METHODS: A hilar cholangiocarcinoma patient of type Bismuch-Corlette IIIa was found with deep jaundice (total bilirubin: 635 µmol/L). On the first admission, we performed Da Vinci robotic surgery including drainage of left hepatic duct, dissection of right hepatic vessels (right portal vein and right hepatic artery), and placement of right-hepatic vascular control device. Three weeks later on the second admission when the jaundice disappeared we occluded right-hepatic vascular discontinuously for 6 days and then sustained later. On the third admission after 3 weeks of right-hepatic vascular control, the right hemihepatectomy was performed by Da Vinci robot for the second time. RESULTS: The future liver remnant after the right-hepatic vascular control increased from 35% to 47%. The volume of left lobe increased by 368 mL. When the total bilirubin and liver function were all normal, right hemihepatectomy was performed by Da Vinci robot 10 weeks after the first operation. The removal of atrophic right hepatic lobe with tumor in bile duct was found with no pathologic cancer remaining in the margin. The patient was followed up at our outpatient clinic every 3 months and no tumor recurrence occurs by now (1 y). CONCLUSIONS: Under the Da Vinci robotic surgical system, a programmed treatment can be achieved: first, the hepatic vessels were controlled gradually together with biliary drainage, which results in liver's partial atrophy and compensatory hypertrophy in the other part. Then a radical hepatectomy could be achieved. Such programmed hepatectomy provides a new treatment for patients of hilar cholangiocarcinoma with deep jaundice who have the possibility of radical heptolobectomy.

Management of bleeding gastric varices in patients with sinistral portal hypertension.

BACKGROUND AND AIM: Sinistral portal hypertension (SPH) is a rare cause of upper gastrointestinal hemorrhage. Besides splenectomy, there is no consensus on the role of sclerotherapy and splenic embolization for bleeding gastric varices (GVs). This retrospective study summarizes our experience in managing GV bleeding from SPH in patients with pancreatic diseases. METHODS: Patients with pancreatic diseases who had bleeding GVs from SPH in two tertiary hospitals were reviewed from January 2001 to December 2011. The etiology, clinical manifestations, diagnostic and therapeutic modalities were analyzed. RESULTS: Twenty-one patients (15.2 %) complicating bleeding GVs among 139 patients with SPH secondary to pancreatic diseases were enrolled. The etiologies were acute pancreatitis in one patient, chronic pancreatitis in seven patients, and pancreatic tumors in 13 patients. Emergent endoscopic sclerotherapy was initially performed in five patients, and succeeded in two patients, while one patient died of massive hemorrhage. Initial transcatheter artery embolization using Gianturco coils was successfully performed in six patients. Splenectomy combined with other surgical procedures was undertaken for 15 patients. The patients undergoing artery embolization or splencetomy achieved hemostasis. The survivors had no recurrent bleeding during a median 72-month follow-up period. CONCLUSIONS: The incidence of bleeding GVs from SPH is relatively rare. Splenic artery embolization could be selected as a first-line choice for bleeding SPH, especially for patients in poor conditions, and sclerotherapy may not be preferentially recommended. Further studies are required to evaluate the optimum treatment algorithm for bleeding GVs from SPH.

Da Vinci robot-assisted anatomic left hemihepatectomy and biliary reconstruction.

BACKGROUND: Since the introduction of Da Vinci robotic surgery, more and more complicated surgeries can now be performed robotically, yet there have been very few on robotic hepatectomy, especially when billiary reconstruction is involved. The video shows our initial experience with an anatomic hepatectomy using Da Vinci surgical robot. In this case, we also conducted billiary reconstruction due to the anatomic abnormality of bile duct, while applying the choledochoscopy. The preoperative diagnosis is primary liver carcinoma, tumor thrombi in bile duct, and hepatitis B. METHODS: First, the gallbladder was resected, and cystic artery and duct were identified. After opening of the common bile duct above the junction, the choledochoscopy was performed. Tumor thrombi were found in common bile duct and left hepatic duct, and they were all removed. Left branches hepatic artery and portal vein were dissected, ligated, and divided. Thrombi in the left hepatic duct were removed also. After marking the cutting line along the ischemic boarder, liver parenchyma was transected using robotic harmonic scalpel. Branches of ducts were encountered and managed by either direct coagulating or dividing after clipping. The left hepatic vein was visualized, exposed, and divided during hepatectomy. Two T tubes were placed into common hepatic duct and the proximal cutting end of right anterior bile duct which was found to join the left hepatic duct, respectively. RESULTS: The operation went on successfully. The operation time was 410 minutes, the blood loss was 200 mL. The pathologic diagnosis was introductal papillary adenocarcinoma of left hepatic duct. The patient went on well postoperatively and was followed up for 22 months till now. Postoperative computed tomography examination showed no recurrence. CONCLUSIONS: Da Vinci-assisted robotic hepatectomy can be performed safely in the hands of experienced hepatobilliary surgeons, and choledochoscopy can be combined for bile duct exploration. With the advantages of Da Vinci robot system, complicated billiary reconstruction can be performed (http://links.lww.com/SLE/A74).

Radiofrequency ablation of splenic tumors: a case series.

Radiofrequency ablation (RFA) for treatment of splenic tumors has rarely been reported. Here we describe our experiences of undergoing RFA in three patients with solitary metastatic (n=2) and benign (n=1) tumors of the spleen. Two patients also had underlying cirrhotic hypersplenism. A 53-year-old male with solitary splenic metastasis from hepatocellular carcinoma underwent laparoscopical RFA of the splenic tumor. Another 61-year-old female with intraabdominal recurrence, focal splenic metastasis from colon cancer and cirrhotic hypersplenism underwent cytoreductive surgery and RFA of splenic tumors. On the third patient, a 32-year-old man with severe hypersplenism, splenic artery steal syndrome and a solitary splenic hemangioma, a laparoscopical RFA of the splenic tumor was performed. The three patients recovered uneventfully. The concurrent hypersplenism of the latter two patients improved significantly. The results indicate that RFA of splenic tumors is feasible and safe, and could be evaluated as an alternative to splenectomy in selected patients with solitary splenic tumors.

Incidence of port-site metastasis after undergoing robotic surgery for biliary malignancies.

AIM: To investigate the incidence of clinically detected port-site metastasis (PSM) in patients who underwent robotic surgery for biliary malignancies. METHODS: Using a prospective database, the patients undergoing fully robotic surgery for biliary malignancies between January 2009 and January 2011 were included. Records of patients with confirmed malignancy were reviewed for clinicopathological data and information about PSM. RESULTS: Sixty-four patients with biliary tract cancers underwent robotic surgery, and sixty patients met the inclusion criteria. The median age was 67 year (range: 40-85 year). During a median 15-mo follow-up period, two female patients were detected solitary PSM after robotic surgery. The incidence of PSM was 3.3%. Patient 1 underwent robotic anatomatic left hemihepatectomy and extraction of biliary tumor thrombi for an Klatskin tumor. She had a subcutaneous mass located at the right lateral abdominal wall near a trocar scar. Patient 2 underwent robotic pancreaticoduodenectomy for distal biliary cancer. She had two metachronous subcutaneous mass situated at the right lateral abdominal wall under a same trocar scar at 7 and 26 mo. The pathology of the excised PSM masses confirmed metastatic biliary adenocarcinoma. CONCLUSION: The incidence of PSMs after robotic surgery for biliary malignancies is relatively low, and biliary cancer can be an indication of robotic surgery.

Clinical characteristics of 327 Asian patients with autoimmune pancreatitis based on Asian diagnostic criteria.

OBJECTIVES: To clarify the clinical and pathophysiological characteristics of autoimmune pancreatitis (AIP) in Asia. METHODS: A retrospective, actual situation survey of AIP diagnosed by Asian criteria was conducted in 10 centers of Japan, Korea, Taiwan, China, and India. RESULTS: A total of 327 AIP cases (258 male and 69 female subjects; average age, 60.0 years) were enrolled. Obstructive jaundice was the most frequent initial symptom (46%-74%), followed by weight loss (4%-51%) and abdominal pain (19%-44%). Diffuse swelling of the pancreas was frequent in Japan (64%) and Korea (81%), but segmental swelling of the pancreas was more frequent in Taiwan (70%) and China (72%) (P < 0.01). Serum immunoglobulin G4 levels were elevated in 58%-100% of cases in Japan, Korea, and Taiwan. Pathologically, almost all AIPs in Asia were lymphoplasmacytic sclerosing pancreatitis. Sclerosing cholangitis was the most frequent extrapancreatic lesion (60%-81%). Steroid therapy was a major and effective therapeutic strategy in Japan, Korea, and Taiwan. However, the rate of resection or bypass operation was higher in Taiwan (40%) and China (72%) (P < 0.01). CONCLUSIONS: Features of AIP are fundamentally similar in Japan, Korea, Taiwan, and China. Knowledge of emerging AIP should be more widespread in Asia to avoid unnecessary operation.

Outcomes of pancreatoduodenectomy with robotic surgery versus open surgery.

BACKGROUND: Pancreatoduodenectomy (PD) for pancreatic cancer is very challenging to many surgeons. Information regarding the advantage of using the Da Vinci robotic system over conventional open surgery for PD is rare. Therefore, a comparison of the outcomes of PD performed using the Da Vinci robotic system with outcomes using open surgery was conducted. METHODS: Between January 2009 and December 2009 sixteen patients underwent PD, eight patients receiving robot-assisted surgery using the Da Vinci surgical robotic system (Group I) and eight being treated using conventional open surgery (Group II). RESULTS: There was no significant difference in radical resection (R0) rate between the two groups, 87.5% vs 100%, P = 0.05. The operative time in group I was longer than in group II, 718 ± 186 vs 420 ± 127 min, P = 0.011, while the surgical blood loss in group I was less than in group II, 153 ± 43 vs 210 ± 53 mL, P = 0.045. The length of bed time and hospital stay after surgery in group I were shorter than in group II, 27.5 ± 7.1 vs 96 ± 18.1 h, P = 0.000; 16.4 ± 4.1 vs 24.3 ± 7.1 days, P = 0.04, respectively). Complication rate of group I was lower than that of group II, 25% vs 75%, P = 0.05. CONCLUSION: It is feasible and safe to perform PD using the Da Vinci robot-assisted surgical system; patients recovered faster postoperatively with less blood loss during surgery.

Two-year follow-up of splenic radiofrequency ablation in patients with cirrhotic hypersplenism: does increased hepatic arterial flow induce liver regeneration?

BACKGROUND: Hepatocyte hypoxia may be a mechanism determining abnormal tissue oxygenation and dysfunction of the cirrhotic liver. Since the introduction of radiofrequency ablation (RFA) for patients with cirrhotic hypersplenism, we observed a phenomenon of visible hepatic regeneration. This study aims to investigate the potential mechanism of RFA-induced liver regeneration, and the 2-year outcomes of splenic RFA. METHODS: Forty patients who underwent splenic RFA for cirrhotic hypersplenism were followed for 24 months. Before and after RFA procedures, portal hemodynamics and liver and spleen volumes were measured by Doppler ultrasonography and computed tomography volumetry. Liver function tests and blood counts were also determined. RESULTS: The splenic and portal venous flows decreased, but hepatic arterial flow (HAF) increased dramatically after the RFA procedure. Liver volumes at 3 month post-RFA increased compared to the baseline volumes (872 +/- 107 vs. 821 +/- 99 cm(3), P = .031). A correlation was found between maximum absolute values of liver volumes (triangle upliver volumes) and that of HAF (triangle upHAF) in Child-Pugh class A/B patients (r = 0.60; P < .001). Leukocyte and platelet counts, as well as liver function, improved substantially during the 2-year follow-up. Patients with > or = 40% of spleen volume ablated had better improvement of thrombocytopenia. No death or severe complications occurred. CONCLUSIONS: RFA for cirrhotic hypersplenism is safe and efficacious. The increase in HAF as a result of splenic RFA may improve liver function and induce liver regeneration in cirrhotics, but further studies are necessary to clarify the underlying mechanisms.

Diagnosis and management of autoimmune pancreatitis: experience from China.

AIM: To determine the clinical, radiographic and pathologic characteristics, diagnostic and treatment modalities in patients with autoimmune pancreatitis (AIP). METHODS: In this retrospective study, the data of patients with diagnosed chronic pancreatitis (CP) between 1995 and 2006 in Chinese PLA General Hospital were included to screen for the cases with AIP, according to the following diagnostic criteria: (1) diagnostic histopathologic features, and abound IgG4-positive plasma cells on pancreatic tissues; (2) characteristic imaging on computed tomography and pancreatography, together with increased serum IgG, gamma-globulin levels or presence of autoantibodies; (3) response to steroid therapy. The clinical, radiographic and pathologic characteristics, diagnostic and treatment modalities, and outcome of AIP cases were reviewed. RESULTS: Twenty-five (22 male, 3 female; mean age 54 years, 36-76 years) out of 510 CP patients were diagnosed as AIP, which accounted for 49% (21/43) of CP population undergoing surgical treatment in the same period. The main clinical manifestations included intermittent or progressive jaundice in 18 cases (72%), abdominal pain in 11 (44%), weight loss in 10 (40%), and 3 cases had no symptoms. The imaging features consisted of pancreatic enlargement, especially in the head of pancreas (18 cases), strictures of main pancreatic duct and intrapancreatic bile duct. Massive lymphocytes and plasma cells infiltration in pancreatic tissues were showed on pathology, as well as parenchymal fibrosis. Twenty-three patients were misdiagnosed as pancreaticobiliary malignancy, and 21 patients underwent exploratory laparotomy, the remaining 4 patients dramatically responded to steroid therapy. No pancreatic cancer occurred during a mean 46-mo follow-up period. CONCLUSION: AIP patients always are subjected to mistaken diagnosis of pancreatic cancer and an unnecessary surgical exploration, due to its similarity in clinical features with pancreatic cancer. The differential diagnosis with high index of suspicion of AIP would improve the diagnostic accuracy for AIP.

Diagnosis and management of primary aortoenteric fistulas--experience learned from eighteen patients.

OBJECTIVE: Misdiagnosis of primary aortoenteric fistula (PAEF) frequently occurs in clinical practice owing to the rarity of this condition. Herein we present the experience of diagnosis and management for PAEF. METHODS: Eighteen patients with PAEF at 2 medical centers in China were reviewed. The clinical data, diagnostic procedures, treatment options, and patient outcomes were evaluated. RESULTS: The fistulas were located at esophagus (5), duodenum (8), jejunum (3), ileum (1), and transverse colon (1). The etiologies include atherosclerotic aneurysms and foreign body. Typical abdominal triad (pain, upper GI bleeding, and abdominal pulsating mass) was found in 27.8% of patients, and Chiari's triad (mid-thoracic pain, sentinel hemorrhage, and massive bleeding after a symptom-free interval) was present in 3 of 5 cases with thoracic aortoesophageal fistulas. All patients had an average of 3.6 (1-9) episodes of gastrointestinal bleeding. The interval between the first sentinel hemorrhage and ultimate exsanguination ranged from 5 hours to 5 months (median, 4 days). Six patients (33.3%) were diagnosed or suggested by diagnostic tools including endoscopy, computerized tomography, and arteriography. Others were diagnosed by surgical exploration (7) and autopsy (5). One to 5 rounds (mean 1.8) of misdiagnosis occurred in 15 patients. Six patients recovered from surgery and remained well during a 36-month follow-up. The surgical options used included in situ replacement with vascular graft (3), aneurysmorraphy and closure of fistula (1), and endovascular stenting (2). CONCLUSIONS: A high index of suspicion is necessary for correct diagnosis and prompt management of PAEF, especially in patients with aortoiliac aneurysms presenting with gastrointestinal bleeding. In situ graft replacement and endovascular stent-graft may be the preferred therapeutic options.

A useful agent for chemoprevention of hepatocellular carcinoma?

Hepatocellular carcinoma (HCC) is a major health problem worldwide, involving more than 620,000 new cases yearly, with chronic HBV and HCV infection being the most common causes. Because most patients are diagnosed in an advanced state which is usually not amenable to curative therapy, prevention should be the main focus for reducing the HCC incidence and its related morbidity and mortality. Strategies of HCC prevention can focus on each single risk factor, with antiviral therapy against chronic hepatitis B and hepatitis C as well as suppression of the progression of common liver diseases being the most important and effective measures. Bicyclol, a drug that can improve liver function and inhibit HBV replication, may be a useful agent for the chemopreventive of HCC, as indicated by a recent study by Zhu et al. Bicyclol can act on the initiation and promotion stages of hepatocarcinogenesis by preventing malignant transformation of hepatic cells. It may also enhance the liver's capacity of detoxification and inhibit DNA mutations. More clinical studies are needed to further demonstrate the efficacy and molecular mechanisms of this agent on HCC chemoprevention.

[Experience of diagnosis and treatment of carcinoma arising from congenital biliary duct cyst].

OBJECTIVE: To summarize the experience in diagnosis, prevention and treatment of carcinoma arising from congenital biliary duct cyst. METHODS: The clinical and pathological data of 185 patients with congenital biliary duct cyst admitted to Chinese PLA General Hospital were analyzed retrospectively. RESULTS: Among 185 patients, twenty-seven cases had carcinomas arising from congenital biliary duct cyst, and the frequency of malignant transformation was 14.6%, which closely related to the age (P < 0.001). The incidences of malignancy for different age groups were: 0 for 0-9 age group, 5.1% for 0-19, 9.1% for 20-29, 16.2% for 30-39, 26.7% for 40-49, 33.3% for 50-59, and 50% for over 60, respectively. Six patients had the history of cyst-enterostomy. Abdominal pain, fever, jaundice and weight loss were the main clinical manifestations. Abdominal ultrasonography, CT, MRI or magnetic resonance cholangiopancreatography, MRCP and endoscopic retrograde choledochopancreatography (ERCP) were the main diagnostic methods. For twenty patients (74.1%), a definite diagnosis was made preoperatively, but it's hard to make an early diagnosis. Nine patients (33.3%) underwent curative resection. CONCLUSIONS: Congenital biliary duct cyst is a premalignant lesion, and the incidence of carcinogenesis increases remarkably with age. The most effective method for prevention of carcinogenesis in choledochal cyst is complete excision of choledochal cyst during childhood, and the prognosis is poor for patients with biliary malignancy.

[Radiofrequency ablation for hypersplenism due to portal hypertension: clinical study].

OBJECTIVE: To investigate the feasibility, efficacy and clinical prospects of radiofrequency ablation (RFA) for hypersplenism in patients with liver cirrhosis and portal hypertension. METHODS: The laboratory and radiologic data over one-year period of patients undergone splenic RFA were analyzed. RESULTS: Nine patients undergone splenic RFA has closely followed-up over 1 year. During hospitalization, no procedure-related complications occurred, only minor complications including hydrothorax (3/9 patients) and mild abdominal pain (4/9 patients) were observed. After treatment, average 30.7% (20%-43%) of spleen volume was ablated, and the platelet count reached peak on 14th post-procedure day. White blood cell and platelet counts, liver function, and hepatic artery blood flow had gained significant improvements comparing with those before RFA procedures. Hyperplasia/regeneration was also occurred in cirrhotic liver after splenic RFA. CONCLUSION: Radiofrequency ablation is a safe, effective and minimally invasive approach for the management of hypersplenism in patients with liver cirrhosis and portal hypertension. Increased hepatic artery blood flow can contribute to significant improvement of liver function, and maybe potentially stimulate liver regeneration in cirrhotic liver.

Radiofrequency ablation for hypersplenism in patients with liver cirrhosis: a pilot study.

Radiofrequency ablation is a relatively new technique used for local ablation of unresectable tumors. We investigated the feasibility and efficacy of radiofrequency ablation for hypersplenism and its effect on liver function in patients with liver cirrhosis and portal hypertension. Nine consecutive patients with hypersplenism due to cirrhotic portal hypertension underwent radiofrequency ablation in enlarged spleens. The ablation was performed either intraoperatively or percutaneously. Patients are followed up for over 12 months. After treatment, between 20% and 43% of spleen volume was ablated, and spleen volume increased by 4%-10.2%. White blood cell count, platelet count, liver function, and hepatic artery blood flow showed significant improvement after 1-year follow-up. Splenic vein and portal vein blood flow were significantly reduced. Only minor complications including hydrothorax (three of nine patients) and mild abdominal pain (four of nine patients) were observed. No mortality or other morbidity occurred. Radiofrequency ablation is a safe, effective, and minimally invasive approach for the management of splenomegaly and hypersplenism in patients with liver cirrhosis and portal hypertension. Increased hepatic artery blood flow may be responsible for sustained improvement of liver condition. Radiofrequency ablation may be used as a bridging therapy for cirrhotic patients waiting for liver transplantation.
