An assessment of surgery for portal hypertensive patients performed at a single community hospital

Efficacy and safety of laparoscopic splenectomy and esophagogastric devascularization for portal hypertension: A single-center experience

Many patients in China have portal hypertension secondary to liver cirrhosis. Splenectomy and devascularization have become an efficacious surgical procedure for portal hypertension, and has been recommended in China as the first choice for the treatment of portal hypertension for a long time. As a result of advances in laparoscopic equipment and techniques, splenectomy and esophagogastric devascularization have been carried out with laparoscope.From January 2012 to December 2017, 453 patients who were diagnosed with portal hypertension and serious gastroesophageal varices received surgical management in our institution. 250 patients chose laparoscopic splenectomy and esophagogastric devascularization and 203 underwent open splenectomy and esophagogastric devascularization.We retrospectively analyzed the perioperative data and follow-up data of these patients. The operation time of laparoscopic group was longer than open group (P ≤ .001). Intraoperative blood loss was less (P ≤ .001), the passing of flatus was earlier (P = .042), and postoperative hospital stay was shorter (P = .001) in the laparoscopic group. During postoperative follow-up of 4 to 75 months, the incidence of esophagogastric variceal rebleeding, encephalopathy, and secondary liver cancer showed no significant differences.Laparoscopic splenectomy and esophagogastric devascularization were safe and more effective than open surgery for portal hypertension and gastroesophageal varices.

Transjugular intrahepatic portosystemic shunt versus open splenectomy and esophagogastric devascularization for portal hypertension with recurrent variceal bleeding

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) and open splenectomy and esophagogastric devascularization (OSED) are widely used to treat patients with portal hypertension and recurrent variceal bleeding (PHRVB). This study aimed to compare the effectiveness between TIPS and OSED for the treatment of PHRVB.

METHODS

The data were retrospectively retrieved from 479 cirrhotic patients (Child-Pugh A or B class) with PHRVB, who had undergone TIPS (TIPS group) or OSED (OSED group) between January 1, 2010 and October 31, 2014.

RESULTS

A total of 196 patients received TIPS, whereas 283 underwent OSED. Within one month after TIPS and OSED, the rebleeding rates were 6.1% and 3.2%, respectively (P=0.122). Significantly lower incidence of pleural effusion, splenic vein thrombosis, and pulmonary infection, as well as higher hepatic encephalopathy rate, shorter postoperative length of hospital stay, and higher hospital costs were observed in the TIPS group than those in the OSED group. During the follow-up periods (29 months), significantly higher incidences of rebleeding (15.3% vs 4.6%, P=0.001) and hepatic encephalopathy (17.3% vs 3.9%, P=0.001) were observed in the TIPS group than in the OSED group. The incidence of in-stent stenosis was 18.9%. The survival rates were 91.3% in the TIPS group and 95.1% in the OSED group. The long-term liver function did not worsen after either TIPS or OSED.

CONCLUSION

For the patients with liver function in the Child-Pugh A or B class, TIPS is not superior over OSED in terms of PHRVB treatment and rebleeding prevention.

Laparoscopic Splenectomy and Esophagogastric Devascularization for Liver Cirrhosis and Portal Hypertension Is a Safe, Effective, and Minimally Invasive Operation

BACKGROUND

In the recent years, laparoscopic splenectomy and esophagogastric devascularization (LSD) for liver cirrhosis and portal hypertension rapidly gained the interest of hepatobiliary surgeons due to its minimal invasion. This study aimed to gather and analyze available data from the observational studies that have compared LSD and open splenectomy and esophagogastric devascularization (OSD) for liver cirrhosis and portal hypertension.

MATERIALS AND METHODS

All the studies comparing LSD and OSD for liver cirrhosis and portal hypertension were searched on the available databases, including the Cochrane Central Register of Controlled Trials, Medline, Science Citation Index, EMBASE, China National Knowledge Infrastructure, Wanfang Database, and China Biomedical Database. Data were analyzed using Review Manager software version 5.0.

RESULTS

After the literature search, a total of 17 studies were included in the meta-analysis, which involved 1093 patients: 552 in the laparoscopic group and 541 in the open group. The laparoscopic group was shown to have a lower overall postoperative complication rate (0.43; 95% confidence interval [CI; 0.29-0.64]) than the open group (P < .0001), which was not associated with heterogeneity between the studies. The laparoscopic group was shown to have a lower intraoperative blood loss (-320.62; 95% CI [-552.35 to -88.9]), shorter time of oral intake (-29.08 hours; 95% CI [-35.28 to -22.88]), and shorter hospital stay (95% CI [-6.19 to -2.19]) than those of the open group (P < .00001). The operative time of the laparoscopic group was 42.16 minutes longer (95% CI [32.20-52.11]) compared with the open group (P < .00001). There was no significant difference of hospitalization costs between the studies.

CONCLUSION

This meta-analysis demonstrated that laparoscopic left lateral resection is a safe and feasible option associated with a reduced overall complication rate. The current evidence suggested that it could be performed routinely in liver centers.

Hypersplenism is correlated with increased risk of hepatocellular carcinoma in patients with post-hepatitis cirrhosis

Several risk factors exist for hepatocellular carcinoma in patients with post-hepatitis cirrhosis (PHC), including hypersplenism. Splenectomy is a common but controversial procedure in the management of hypersplenism, but its impact on hepatocellular carcinoma (HCC) remains uncertain. We conducted a hospital-based study of PHC patients to identify potential risk factors, including a history of splenectomy, which has been associated with progression from PHC to HCC. From 2002 to 2012, 2678 patients developed hypersplenism secondary to PHC. Of these patients, 828 developed HCC and 1850 did not. Potential risk factors of HCC were determined by univariate and multivariate analyses to exclude confounding variables. Odds ratios (ORs) and 95 % confidence intervals (95 % CIs) were determined for each factor. Many factors, such as liver function, platelet (PLT) counts, Child-Pugh class, and history of hepatitis, were associated with progression to HCC. PHC patients with hypersplenism who displayed elevated levels of alanine transaminase (ALT), aspartate transaminase (AST), γ-glutamyltransferase (GGT), ALK, phosphatase, and prolonged prothrombin time (PT) had a significantly increased risk of HCC. However, the patients who had splenectomy showed better liver function test results and less progression to HCC. In patients with PHC and hypersplenism, abnormal levels of ALT, AST, ALP, and GGT and prolonged PT are risk factors of HCC. Splenectomy, as the intervention method of hypersplenism, is performed less frequently in patients who developed HCC than in patients who did not develop HCC. Therefore, splenectomy may act as an independent factor that is significantly associated with HCC development.

Laparoscopic Versus Open Splenectomy for Portal Hypertension

Background. Laparoscopic splenectomy has become the gold-standard procedure for normal to moderately enlarged spleens. However, the safety of laparoscopic splenectomy for patients with portal hypertension remains controversial. We carried out this systematic review to identify the feasibility and safety of laparoscopic splenectomy in treating portal hypertension. Data sources. A systematic search for comparative studies that compared laparoscopic splenectomy with open splenectomy for portal hypertension was carried out. Studies were independently reviewed for quality, inclusion and exclusion criteria, demographic characteristics, and perioperative outcomes. Conclusion. Although laparoscopic splenectomy is associated with longer operating time, it offers advantages over the open procedure in terms of less blood loss, lower operative complications, earlier resumption of oral intake, and shorter posthospital stay. Therefore, laparoscopic splenectomy is a safe and feasible intervention for portal hypertension.

Transumbilical single-incision laparoscopic splenectomy plus pericardial devascularization using conventional instruments: initial experience of 5 cases

PURPOSE

Laparoendoscopic single-site surgery (LESS) has been proposed for several intra-abdominal surgical interventions. However, application of the LESS technique in portal hypertension is still in its infancy. We report in this article a new technique of LESS splenectomy plus pericardial devascularization with conventional laparoscopic instruments in patients with portal hypertension.

PATIENTS AND METHODS

From January 2010 to April 2012, LESS splenectomy plus pericardial devascularization was performed on 5 patients with portal hypertension. Surgical techniques and short-term outcomes were summarized and analyzed retrospectively.

RESULTS

All the operations were successful with a mean operative duration of 252 minutes (range, 220-270 minutes), intraoperative blood loss of 290 mL (range, 250-350 mL), and hospital stay of 8.2 days (range, 7-9 days). No intraoperative or postoperative complications were recorded. The umbilical incision healed well with a satisfactory cosmetic effect.

CONCLUSIONS

LESS splenectomy plus pericardial devascularization is feasible when performed by experienced laparoscopic surgeons and may offer safety comparable to that of the conventional laparoscopic operation.

Laparoscopic splenectomy and esophagogastric devascularization is a safe, effective, minimally invasive alternative for the treatment of portal hypertension with refractory variceal bleeding

Open splenectomy and esophagogastric devascularization (OSED) is a typical surgery for portal hypertension. Because of the high morbidity associated with it, it is desirable to develop a minimally invasive alternative. To investigate the safety and effect of laparoscopic splenectomy and esophagogastric devascularization (LSED), we performed LSED for 24 patients suffering from portal hypertension with refractory variceal bleeding while conducting OSED for 30 patients. The perioperative data and follow-up results were analyzed. Operation times were similar in both groups. Less intraoperative blood and faster return of gastrointestinal function were found in the LSED group. The LSED group had lower levels of alanine aminotransferase, aspartate aminotransferase, and total bilirubin after surgery. In both groups, the levels of platelet count, white blood cell count, or hemoglobin were increased after operation dramatically. During the follow-up period (range = 3-36 months), no patient had recurrent hypersplenism or variceal bleeding. Hence, LSED is a safe and minimally invasive intervention for portal hypertension with refractory variceal bleeding.

Implications of portal vein thrombosis after splenectomy for patients with idiopathic portal hypertension

PURPOSE

Idiopathic portal hypertension (IPH) is considered to be closely related to portal vein thrombosis (PVT). The aim of this study was to clarify the incidence, clinical characteristics, and outcomes of PVT in patients with IPH after splenectomy.

METHODS

We investigated the rates, clinical characteristics, and outcomes of PVT in 18 patients who underwent splenectomy for IPH, during a mean follow-up period of 152 ± 83 months.

RESULTS

Seven of the 18 patients (39%) experienced gastrointestinal bleeding, which was from the varices in 4. Eight patients (44%) had PVT, and the mean interval until its detection after splenectomy was 22 ± 41 months. The cumulative gastrointestinal bleeding rates 5, 10, and 15 years after surgery were 24%, 31%, and 41%, respectively. The cumulative survival rates 5, 10, and 15 years after surgery were 94%, 74%, and 65%, respectively. There were no significant differences in the cumulative gastrointestinal bleeding and survival rates between patients with and those without PVT.

CONCLUSION

Despite the high incidence of PVT in IPH patients postsplenectomy, it may not be related to their gastrointestinal bleeding or prognosis.
