Experience with radical esophagogastric devascularization procedures (Sugiura) for variceal bleeding outside Japan

Long-term results of the paraesophagogastric devascularization with or without esophageal transection: which is more suitable for variceal bleeding?

BACKGROUND

It has been reported that the paraesophagogastric devascularization with esophageal transection procedure, also known as the modified Sugiura procedure, was effective in the treatment of variceal bleeding. However, it was not widely accepted by other surgeons because of the high rate of rebleeding, complications, and mortality. To discover the effects of the paraesophagogastric devascularization procedure and the modified Sugiura procedure, we retrospectively analyzed the outcomes of these two procedures.

MATERIALS AND METHODS

During January 1990 and December 2009, 278 patients with variceal bleeding underwent devascularization after failed pharmacotherapy and endotherapy. In these 278 patients, 180 underwent paraesophagogastric devascularization without esophageal transection (group I), and the other 98 patients were subjected to the modified Sugiura procedure (group II).

RESULTS

Postoperative mortality was 7.2% in group I, and 9.2% in group II (P = 0.563). The postoperative rebleeding rate in the two groups was 2.2 and 3.1%, respectively (P = 0.474). After a mean follow-up of 67.9 ± 37.3 months and 67.4 ± 44.6 months, respectively, esophageal transaction-related morbidity (leak, bleeding, and stricture) was 8.2% (8/98) in group II and 0% (0/180) in group I (P < 0.001). The overall rebleeding rate was 27% (41/152) in group I, and 27.2% (22/81) in group II (P = 0.976). The overall mortality was 28.3% (43/152) in group I, and 28.4% (23/81) in group II (P = 0.986).

CONCLUSIONS

In the management of variceal bleeding, paraesophagogastric devascularization without esophageal transection is as effective and safe as devascularization with esophageal transaction, but with less esophageal transection-related morbidity.

Esophagogastric devascularization without splenectomy in portal hypertension: safe and effective?

BACKGROUND

Esophagogastric variceal hemorrhage is a life-threatening complication of portal hypertension. In this study, we compared the therapeutic effect of a novel surgical procedure, esophagogastric devascularization without splenectomy (EDWS), with the widely used modified esophagogastric devascularization (MED) with splenectomy for the treatment of portal hypertension.

METHODS

Fifty-five patients with portal hypertension were included in this retrospective study. Among them, 27 patients underwent EDWS, and the other 28 patients underwent MED. Patients' characteristics, perioperative parameters and long-term follow-up were analyzed.

RESULTS

The portal venous pressure was decreased by 20% postoperatively in both groups. The morbidity rate of portal venous system thrombosis in the EDWS group was significantly lower than that in the MED group (P=0.032). The 1- and 3-year recurrence rates of esophagogastric variceal hemorrhage were 0% and 4.5% in the EDWS group, and 0% and 8.7% in the MED group, respectively (P=0.631).

CONCLUSIONS

EDWS is a safe and effective treatment for esophagogastric varices secondary to portal hypertension in selected patients. Patients treated with EDWS had a lower complication rate of portal venous system thrombosis compared with those treated with conventional MED.

Laparoscopic splenectomy plus preoperative endoscopic variceal ligation versus splenectomy with pericardial devascularization (Hassab's operation) for control of severe varices due to portal hypertension

BACKGROUND

Our research was conducted to introduce a new, compound surgical method for laparoscopic splenectomy (LS) with preoperative endoscopic variceal ligation (EVL) and compare the new method's efficiency with that of Hassab's operation in patients with severe esophageal varices due to portal hypertension.

METHODS

Between March 2009 and March 2012, 47 patients with liver cirrhosis, portal hypertension, and severe esophageal varices were retrospectively analyzed. Of these patients, 19 received the combined preoperative EVL and LS (minimally invasive surgery, MIS group), and 28 patients received splenectomy with pericardial devascularization (Hassab's operation, H group).

RESULTS

Before surgery, there were no differences in the patient characteristics of the two groups. There were no significant differences in operating time, but significantly less intraoperative blood loss and shorter postoperative hospital stay were found in the MIS group compared with the H group. The mean follow-up periods of the MIS and H groups were 12.1 and 13.6 months, respectively. No deaths were documented during the follow-up period. Generally, hematological parameters and liver function variables eventually revealed considerable improvement in both groups. In the MIS group, the patients with varices improved significantly from severe to mild, and in some cases, the varices disappeared after treatment. Three patients in the H group suffered rebleeding and were treated with repeated EVL. No bleeding or rebleeding occurred in the MIS group.

CONCLUSIONS

The final results suggest that LS with preoperative EVL provides a restorative efficacy equivalent to that of Hassab's operation. Based on the recurrence rate and the rebleeding rate of severe esophageal varices, our surgical strategy (EVL and LS) is a safe and minimally invasive technique that appears satisfactory in comparison to other open procedures.

Long-term results with the modified Sugiura procedure for the management of variceal bleeding: standing the test of time in the treatment of bleeding esophageal varices

Background

The surgical approaches to the treatment of bleeding esophageal varices in cirrhotic patients have been reduced since the clinical development of endoscopic sclerotherapy, transjugular intrahepatic portosystemic shunt (TIPS), and liver transplantation. However, when acute sclerotherapy fails, and in cases where no further treatment is accessible, emergency surgery may be life saving. In the present study we retrospectively analyzed the results of the modified Sugiura procedure, performed as emergency and semi-elective treatment in the patient with bleeding esophageal varices.

Methods

Ninety patients with cirrhosis and portal hypertension were managed in our department for variceal esophageal bleeding between January 1985 and December 1992. The modified Sugiura procedure was performed in 46 patients on an emergency (25 patients) or semi-elective (21 patients) basis. Liver cirrhosis stage according to Child classification was A in 4 patients, B in 16 patients, and C in 26 patients.

Results

Acute bleeding was controlled in all patients. Postoperative mortality was 23.9% (11 of 46 patients). The mortality rate was 34.6% in Child class C patients (9 of 26 patients), and 12.5% in Child class B patients (2 of 16 patients). Twenty-four patients had long-term follow-up extending from 14 months to 22 years (mean 83.1 months). Ten of 24 patients (41.6%) did not develop rebleeding for 5–22 years (mean 10.3 years). Overall 5-year survival in these 24 patients was 62.5%.

Conclusions

The modified Sugiura procedure remains an effective rescue therapy for patients with bleeding esophageal varices when alternative treatments fail or are not indicated. Moreover, it can be a life-saving procedure in patients with anatomy unsuitable for shunt surgery or for patients treated in nonspecialized centers where surgical expertise for a shunt operation is not available.

Randomized clinical trial of vessel sealing system (LigaSure) in esophagogastric devascularization and splenectomy in patients with portal hypertension

BACKGROUND

The LigaSure vessel sealing system (Valleylab, Boulder, CO) has been tested, with excellent results, in different fields of surgery. However, no study has evaluated the efficiency of the LigaSure in open esophagogastric decongestion and splenectomy in a randomized trial to date.

METHODS

Patients scheduled to undergo esophagogastric decongestion and splenectomy were assigned to the use of either the LigaSure or a conventional clamp-and-tie technique. Primary outcome measures were operating time and intraoperative blood loss. Secondary outcome measures were postoperative drainage volume, complications such as spleen fever, bleeding, portal vein thrombosis, length of incision, pain, and time to discharge.

RESULTS

Sixty patients were randomized to the LigaSure (n = 30) and clamp-and-tie (n = 30) groups. The groups were well matched with respect to liver function, associated illnesses, and grading of esophageal varices. Postoperative outcomes in drainage and major complications did not differ between the groups, while operative time and the volume of blood loss were significantly decreased in the LigaSure group compared with the clamp-and-tie group (P < .001).

CONCLUSIONS

The use of the LigaSure is safe and effective in vessel division and homeostasis in the esophagogastric decongestion and splenectomy, with statistically significant decreases in operative time and intraoperative blood loss and without significantly modifying postoperative results.

Effects of modified splenocaval shunt plus devascularization on esophagogastric variceal bleeding: a comparative study of this treatment and devascularization only in cirrhotic portal hypertension

BACKGROUND

Pericardial devascularization (PCDV) and portosystemic shunt were reported to have favorable results for the management of portal hypertension in cirrhotic patients in China and the West, respectively. This study was undertaken to investigate the effects of a modified proximal splenocaval shunt plus PCDV on variceal bleeding in patients with portal hypertension.

METHODS

From January 1997 to December 2007, 168 patients with portal hypertension of cirrhotic origin received an operation for gastroesophageal variceal bleeding. Of these, 90 patients received a splenocaval shunt plus a PCDV procedure (Combined Group) and the other 78 patients received a PCDV procedure only (PCDV Group). The procedure-related morbidity and mortality, rebleeding, encephalopathy, and survival rates were analyzed.

RESULTS

Postoperative mortality was 3.3% in the combined group and 5.1% in the PCDV group (P > 0.05). Overall morbidity was 13.3% in the combined group and 15.4% in the PCDV group (P > 0.05). The rate for rebleeding, including variceal bleeding and gastropathy, was 5.1% in the combined group, which was significantly lower than that in the PCDV group, at 16.7% (P < 0.05). The incidence of encephalopathy was 6.63% in the combined group and 6.67% in the PCDV group (P > 0.05). The 1-, 3-, 5- and 10-year survival rates were 97.4, 91.7, 80.0, and 60.0% in the combined group and 96.7, 83.3, 73.3, and 53.3% in the PCDV group (P > 0.05).

CONCLUSIONS

The modified splenocaval shunt plus PCDV is a safe and effective procedure for the long-term control of variceal bleeding; the procedure may not only maintain the portal flow to the liver, but may also protect the liver function in cirrhotic patients. The better clinical outcome means that the procedure may be one of the best choices for treating portal hypertension of cirrhotic origin.

Severe bleeding from esophageal varices resistant to endoscopic treatment in a non cirrhotic patient with portal hypertension

A non cirrhotic patient with esophageal varices and portal vein thrombosis had recurrent variceal bleeding unsuccessfully controlled by endoscopy and esophageal transection. Emergency transhepatic portography confirmed the thrombosed right branch of the portal vein, while the left branch appeared angulated, shifted and stenotic. A stent was successfully implanted into the left branch and the collateral vessels along the epatoduodenal ligament disappeared. In patients with esophageal variceal hemorrhage and portal thrombosis if endoscopy fails, emergency esophageal transection or nonselective portocaval shunting are indicated. The rare patients with only partial portal thrombosis can be treated directly with stenting through an angioradiologic approach.

Transabdominal modified devascularization procedure with or without esophageal stapler transection--an operation adequate for effective control of a variceal bleed. Is esophageal stapler transection necessary?

BACKGROUND

In Japan, the original Sugiura procedure reported favorable results in non-cirrhotic patients but in the West, the modified Sugiura procedure is not widely accepted because of high rebleeding, morbidity, and mortality in cirrhotics. We retrospectively analyzed the efficacy of our modified Sugiura procedure i.e., devascularization with/without esophageal transection combined with salvage endotherapy and pharmacotherapy for control of a variceal bleed.

MATERIALS AND METHODS

Between January 1999 and December 2004, 912 patients with variceal bleeding were treated. Of these, 66 (7.2%) patients were subjected to surgery after failed endotherapy/propranolol. Among these 66 patients, 52 had transabdominal devascularization (16 emergency, 36 elective); 14 patients underwent devascularization with esophageal stapler transection (group I), and 38 patients had devascularization without esophageal stapler transection (group II). Another 14 patients underwent elective end-to-side proximal splenorenal shunt surgery.

RESULTS

Postoperative mortality was 7.1% in group I, 10.5% in group II (P>0.05). Mortality for emergency surgery was 31.2% (5/16) but there were no deaths in the elective surgery group. Overall morbidity was 57.1% in group I and 21.0% in group II (P<0.05). The rates of variceal rebleeding were 7.1% and 7.8%; residual varices were 30.7% and 32.3%; recurrent varices were 7.6% and 5.8% following the group I and group II procedures, respectively, over a mean follow-up period of 39.9 (7-2) months. Esophageal transection-related morbidity (leak, stricture, and bleeding) was 21.4% (3/14) in group I.

CONCLUSIONS

Devascularization without esophageal stapler transection is a safe and effective procedure for adequate (urgent and long-term) control of variceal bleeding with similar results and less morbidity when compared to devascularization with esophageal transection in cirrhotic patients, as well as non-cirrhotic patients.

Transabdominal gastro-esophageal devascularization and esophageal transection for bleeding esophageal varices after failed injection sclerotherapy: long-term follow-up report

BACKGROUND

Management of continued bleeding from esophageal varices despite adequate injection sclerotherapy remains one of the medical and surgical dilemmas. Transabdominal gastroesophageal devascularization and esophageal transection (TGDET) is considered an effective and safe procedure for such patients.

AIM

This study aimed at presenting continued evaluation of TGDET. Various problems influencing the early outcome are discussed, and long-term outcome is analyzed.

DESIGN

This was a prospective clinical descriptive study.

METHODS

Prospective data was collected on 142 consecutive patients managed by one group of surgeons over a 5 year-period and 15 years follow-up after failed injection sclerotherapy for variceal bleeding. Evaluation was made in terms of effectiveness in controlling the acute bleeding, postoperative morbidity and mortality, recurrent bleeding, encephalopathy, and long-term survival.

RESULTS

There were 133 men and 9 women. Mean age was 41.8 years. Etiology of portal hypertension was bilharziasis in 54.9% and posthepatitic in 14.8%. Child-Pugh grading on admission was A: 47.2%, B: 28.8%, and C: 14%. Hemorrhage was controlled in all cases. Clinical leak was observed in 5.6%, portal vein thrombosis in 6.3%, and staple line erosion in 2.1% of cases. No patient developed encephalopathy. In-hospital mortality was 12.7%. Complete eradication of varices was observed in 70.6% patients. Recurrent variceal bleeding was noticed in 6.9% of cases. Actuarial 15-year survival for Child-Pugh A patients was 44%, B was 22.5%, and none for C.

CONCLUSION

TGDET remains a safe and effective procedure after failure of sclerotherapy when other alternatives are either not indicated or not available.

Hand-assisted laparoscopic splenectomy and devascularization of the upper stomach in the management of gastric varices

BACKGROUND

Bleeding from esophagogastric varices is the major cause of death in patients with portal hypertension. Although esophageal varices can be treated with endoscopic procedures, the treatment for gastric varices is still controversial. The aim of this study was to describe a surgical technique and our preliminary results of hand-assisted laparoscopic Hassab's procedure.

METHODS

Between February 2002 and May 2005, we performed 7 cases of gastric varices with this type of operation. The patients included 4 men and 3 women who ranged in age from 23 to 74 years (underlying liver disease: 5 case of liver cirrhosis, 1 case of polycystic disease, 1 case of extrahepatic portal vein obstruction). After splenctomy was performed, we devascularized the vessels of the upper stomach and the esophagus 5 cm away from the esophago-cardia junction.

RESULTS

The operative time ranged from 132 to 290 minutes. Intraoperative blood loss was estimated to be from 50 ml to 475 ml. The weight of removed spleen ranged from 110 g to 800 g. During the follow-up period, all gastric varices disappeared and no bleeding from varicose veins was observed. All patients had hypersplenism with thrombocytopenia before surgery (mean: 11.1+/-7.4x10(4)/ml), which was improved postoperatively (mean: 30.8+/-19.0x10(4)/ml). This data were statistically significant (P=0.033). One patient died of aspiration pneumonia related to postoperative pyloric stricture.

CONCLUSIONS

Although there is no agreement concerning the best treatment of gastric varices, the hand-assisted laparoscopic Hassab's operation is a safe, moderately invasive method, and its outcome appears to be equal to that of other open procedures.

Preoperative Evaluation of Endoscopic Ultrasonography and Portography in Selecting Devascularization Surgery for Esophagogastric Varices

This study assesses the role of endoscopic ultrasonography (EUS) and portography in selection of mode of devascularization surgery for esophagogastric varices (EGV) in patients with portal hypertension and reports our experience in the treatment of EGV with modified devascularization surgery. Forty-two cirrhotic patients with EGV were treated with devascularization surgery for variceal hemorrhage. Preoperatively, percutaneous transhepatic portography (PTP) and EUS were used as the guiding mode for therapy of EGV. In addition to devascularization and splenectomy, esophageal transection (ET) was performed in 26 patients with upward-flow varices (UFV), whereas 16 patients with downward-flow varices (DFV) underwent proximal gastrectomy instead of ET. In both UFV and DFV groups, grade II of intramural varices and extramural collaterals were most commonly observed on EUS imaging. There was no significant difference of EUS grading between these two groups ( P > 0.05). The incidence of postoperative complications, mortality, and recurrent varices were not significantly different between these two groups. The overall 5-year survival rate for UFV group was 69.2 per cent, whereas that for the DFV group was 68.7 per cent ( P > 0.05). Our study shows that devascularization surgery is highly effective for the prevention of recurrent bleeding from EGV, and it provides an alternative treatment modality. Combined PTP and EUS are very helpful in determining adequate modalities of devascularization surgery.

Novel technique of laparoscopic azygoportal disconnection for treatment of esophageal varicosis: preliminary experience with five patients

BACKGROUND

Liver cirrhosis leads frequently to the development of ascites and a formation of varicose veins in the esophagus. The latter presents increased mortality risk. Recently, significant progress in laparoscopic technology enabled devascularization of the proximal stomach in a less invasive way. The results experienced by five patients are presented.

METHODS

Laparoscopic azygoportal disconnection was performed by means of novel technique (Danis procedure) in five men with esophagus varices bleeding (2nd to 11th events) and liver cirrhosis stage Child-Pugh B and C. This procedure was performed after all other methods had either failed to prevent recurrent bleeding or were refused by the patient. Five ports were positioned on the upper abdominal wall. The veins in the lesser omentum were divided by means of the LigaSure-Atlas device. The stomach coronary vein was visualized, and all the proximal branches toward the esophagus as well as the short gastric vessels were divided. The diaphragm hiatus was opened, and the distal esophagus was dissected. The paraesophageal venous collaterals also were divided, and the remaining varicose veins of the esophagus were interrupted by transmural stitching.

RESULTS

All the patients survived the minimally invasive procedure. Two of them died 9 and 16 months after surgery, respectively, because of liver insufficiency. No bleeding event from varicose veins in the esophagus occurred postoperatively.

CONCLUSION

Laparoscopic azygoportal disconnection is a less invasive method for prevention of rebleeding from varicose veins in the esophagus. Further studies are necessary to confirm these preliminary results.

Current indication of a modified Sugiura procedure in the management of variceal bleeding

BACKGROUND

The role of gastroesophageal devascularization (Sugiura-rype procedures) for the treatment of variceal bleeding remains controversial. Although Japanese series reported favorable longterm results, the technique has nor been widely accepted in the Western Hemisphere because of a high postoperative morbidity and mortality. The reasons for the different outcomes are unclear. In a multidisciplinary team approach we developed a therapeutic algorithm for patients with recurrent variceal bleeding.

STUDY DESIGN

The Sugiura procedure was offered only to patients with well-preserved liver function (Child A or Child B cirrhosis without chronic ascites) who were not candidates for distal splenorenal shunt, transhepatic porto-systemic shunt, or liver transplantation.

RESULTS

Fifteen patients with recurrent variceal bleeding underwent a modified Sugiura procedure between September 1994 and September 1997. All but one patient (operative mortality 7%) are alive after a median followup of 4 years. Recurrent variceal bleeding developed in one patient; esophageal strictures, which were successfully treated by endoscopic dilatation, developed in three patients; and one patient experienced mild encephalopathy. Major complications were noted only in patients with impaired liver function (Child B cirrhosis) or when the modified Sugiura was performed in an emergency setting. The presence of cirrhosis or the cause of portal hypertension had no significant impact on the complication rate.

CONCLUSIONS

This series was performed during the last decade when all modern therapeutic options for variceal bleeding were available. Our results indicate that the modified Sugiura procedure is an effective rescue therapy in patients who are not candidates for selective shunts, transhepatic porto-systemic shunt, or transplantation. Emergency settings and decreased liver function are associated with an increased morbidity.

Salvage therapies for refractory variceal hemorrhage

Refractory variceal bleeding is defined as bleeding that continues through adequate pharmacologic and endoscopic therapy. In patients with end-stage liver disease, the only option for long-term salvage is liver transplantation. In patients with well-preserved liver function (Child's class A and class B-7), other salvage options such as surgical shunt, TIPS, and devascularization procedures can achieve good outcome. The long-term survival depends on the underlying liver disease, rather than on the variceal bleeding per se.

A modified technique of devascularization for surgical management of portal hypertension in children

In developing countries surgery is indicated in patients with portal hypertension for a variety of reasons. This study prospectively evaluates a modified technique of devascularization for secondary prophylaxis of variceal bleeding in patients with portal hypertension of different aetiologies. Transabdominal extensive oesophagogastric devascularization combined with transmural ligation of oesophageal and gastric varices was performed in 16 paediatric patients (nine with extrahepatic portal venous obstruction, and seven with non-cirrhotic portal fibrosis) in an elective setting. The Sugiura devascularization procedure was modified to minimize the operating time and to avoid the problems associated with oesophageal transection and anastomosis. The operative mortality rate as well as the oesophageal leak rate was zero. One patient developed an oesophageal stricture. During a 12-month follow-up, patients were seen with residual varices (2), recurrent varices (3) and rebleeding (1). Porto-systemic encephalopathy was seen in one patient only. This technique is a simple, straightforward, safe and effective modification of the Sugiura procedure in controlling bleeding, providing good quality of life with minimal porto-systemic encephalopathy.

Surgical treatment of portal hypertension

The surgical treatment of portal hypertension has laxed and waned over the past century. Decompressive shunts for variceal bleeding hit their peak in the 1970s, but dissatisfaction with encephalopathy and liver failure led to further developments with selective shunts and devascularization procedures in the 1970s and early 1980s. Liver transplant is the major operative intervention currently in use and of advantage to patients with portal hypertension. The role of the surgeon is as part of the team involved in the full evaluation of patients with cirrhosis and portal hypertension with its complications. The current repertoire of surgical options includes decompressive shunts, either total, partial or selective, devascularization procedures and liver transplantation. These options must be fitted into the overall management schema of pharmacologic and endoscopic therapy as the first-line approaches to managing these patients.

Surgery in portal hypertension

The role of surgery in portal hypertension remains a topic of debate. For the past 100 years, various surgical procedures have been used to treat variceal bleeding, refractory ascites, and end-stage liver disease. The past decade has seen significant advances in pharmacotherapy, endoscopy, interventional radiology, and surgery for the management of patients with portal hypertension. Liver transplantation has come of age in the 1990s and is now an accepted therapy for patients with end-stage liver disease. The wide array of management options can complicate the decision making process and defines the need to evaluate these patients fully. Factors such as the aetiology and extent of liver disease, response to prior medical, endoscopic, and other interventional treatments, and possibility of future liver transplantation must be considered. This manuscript will review the history of surgical treatments of portal hypertension, describe the surgical procedures with their advantages and disadvantages, and evaluate their role in the elective and emergent settings.

The role of surgery in the treatment of portal hypertension

The role of surgery in the treatment of portal hypertension continues to evolve. Pharmacologic and endoscopic therapies are the primary treatment modalities for the prophylaxis and treatment of variceal bleeding and ascites. Failure of these therapies is the indication for invasive intervention such as TIPS, surgical shunt, or devascularization. Distal splenoreal shunting provides selective variceal decompression with less encephalopathy and accelerated hepatic failure than portal decompression. Liver transplantation remains the treatment of choice for patients with poor hepatic function.

Transabdominal esophagogastric devascularization as treatment for variceal hemorrhage

BACKGROUND

During the past 18 years we have used a selective operative approach for variceal bleeders in whom endoscopic sclerotherapy failed or sclerotherapy was not indicated. Esophagogastric devascularization with splenectomy has been reserved for unshuntable patients and for those in whom a shunt was deemed inadvisable. The purposes of this study are to describe the surgical procedure technique and indications for esophagogastric devascularization and to report its long-term results.

METHODS

Thirty-two patients who underwent either a limited (n = 9) or extensive (n = 23) esophagogastric devascularization procedure without esophageal transection for variceal bleeding were retrospectively reviewed. Common indications were thrombosis of all splanchnic veins (n = 12), distal splenorenal shunt thrombosis (n = 7), generalized portal hypertension with isolated splenic vein thrombosis (n = 5), and symptomatic splenomegaly or severe hypersplenism (n = 6). Eighteen patients (56%) had cirrhosis, eleven (34%) received an emergency operation, and eighteen (56%) bled from gastric varices.

RESULTS

Three patients with Child's class C disease undergoing emergency surgery died during the early postoperative interval. Rebleeding occurred in nine surviving patients (31%) and was the cause of death in three. Rebleeding rates for the limited and extensive devascularization procedures were 50% and 24%, respectively. Only one of 11 patients with diffuse splanchnic venous thrombosis without liver disease has died. The 5-year survival rate of patients with liver disease was 51%. Only two patients experienced postoperative encephalopathy.

CONCLUSIONS

When used in selected patients, esophagogastric devascularization without esophageal transection is a reasonably effective alternative to shunt surgery.
