The evolving role of endoscopic treatment for bleeding esophageal varices.

The treatment of acute and recurrent variceal bleeding is best accomplished by a skilled, knowledgeable, and well-equipped team using a multidisciplinary integrated approach. Optimal management should provide the full spectrum of treatment options including pharmacologic therapy, endoscopic treatment, interventional radiologic procedures, surgical shunts, and liver transplantation. Endoscopic therapy with either band ligation or injection sclerotherapy is an integral component of the management of acute variceal bleeding and of the long-term treatment of patients after a variceal bleed. Variceal eradication with endoscopic ligation requires fewer endoscopic treatment sessions and causes substantially less esophageal complications than does injection sclerotherapy. Although the incidence of early gastrointestinal rebleeding is reduced by endoscopic ligation in most studies, there is no overall survival benefit relative to injection sclerotherapy. Simultaneous combined ligation and sclerotherapy confers no advantage over ligation alone. A sequential staged approach with initial endoscopic ligation followed by sclerotherapy when varices are small may prove to be the optimal method of reducing variceal recurrence. Overall, current data demonstrate clear advantages for using ligation in preference to sclerotherapy. Ligation should therefore be considered the endoscopic treatment of choice in the treatment of esophageal varices.

Primary hydatid cysts of the pancreas.

Pancreatic involvement by hydatid disease is uncommon. Establishing a precise diagnosis may be difficult because the presenting symptoms and findings of investigations may be similar to other more commonly encountered cystic lesions of the pancreas. We report 4 patients with primary hydatid cysts in the head of the pancreas. The records of all patients treated for hydatid disease from 1980 to 2000 were reviewed. During the study period a total of 280 patients were treated, 4 of whom had hydatid disease involving only the pancreas. The 4 patients (3 women, 1 man) ranged in age from 17 to 60 years. Three patients presented with jaundice, abdominal pain and weight loss, 2 with hepatomegaly and 1 with an epigastric mass. All 4 lesions involved the head of the pancreas and ranged in size from 3 to 10 cm in diameter. In 2 patients the investigations incorrectly suggested a cystic tumour and both underwent pancreaticoduodenectomy. In 2 patients the correct diagnosis allowed local excision to be performed. Hydatid cyst is a rare cause of a cystic mass in the head of the pancreas, but should be included in the differential diagnosis of cystic lesions of the pancreas, especially in endemic areas.

Variceal rebleeding and recurrence after endoscopic injection sclerotherapy: a prospective evaluation in 204 patients.

HYPOTHESIS: Eradication of esophageal varices by repeated injection sclerotherapy and maintenance of eradication using continued surveillance endoscopy may reduce recurrent variceal bleeding and death from esophageal varices. DESIGN: A prospective study of consecutive adult patients with endoscopically proved esophageal variceal bleeding. SETTING: A tertiary care university hospital in a metropolitan area. PATIENTS: Two hundred four patients (127 men and 77 women; mean age, 50.1 years; age range, 16-82 years) underwent 993 emergency and elective variceal endoscopic injection treatments with 5% ethanolamine oleate during 1992 endoscopy sessions. Most (166 [81.4%]) had cirrhosis, mainly due to alcohol abuse (131 [78. 9%]). The number of patients with each modified Pugh-Child risk grade was as follows: A, 30; B, 91; and C, 83. (The modified Pugh-Child classification comprises ascites, encephalopathy, serum albumin and bilirubin levels, and prothrombin time. Each variable is given a value of 1 to 3 with increasing impairment of liver function. Addition of the values leads to the Pugh-Child risk grades for each patient, with 5 and 6 giving grade A; 7 through 9, grade B; and 10 through 15, grade C, respectively.) RESULTS: Ninety-five patients (46.6%) rebled at a median of 17 days (range, 0-2583 days). Seventy-four patients (36.3%) had a total of 112 further bleeding episodes before eradication of varices. Varices were eradicated in 99 (87.6%) of 113 patients who survived longer than 3 months after a median of 5 injections and remained eradicated in 43 (mean follow-up after eradication, 38 months; range, 4-125 months). Rebleeding was markedly reduced after eradication of varices. Varices recurred in 56 patients, of whom only 10 rebled from recurrent esophageal varices. Cumulative survival by life table analysis was 55%, 41%, and 30% at 1, 3, and 5 years, respectively. One hundred thirty-seven patients (67.2%) died during follow-up. Liver failure was the most common cause of death. Minor complications (mucosal ulceration) occurred in 105 patients. Major complications, including a localized injection site leak (n = 9), esophageal stenosis (n = 25), and esophageal perforation (n = 5), occurred in 39 patients. CONCLUSIONS: Repeated injection sclerotherapy eradicated esophageal varices in most long-term patients. Complications related to injection sclerotherapy were mostly minor. Complete eradication of varices reduced rebleeding and death from esophageal varices.

Endoscopic treatment of oesophageal varices.

Major variceal bleeding is a life-threatening complication of portal hypertension. Therapy for bleeding may be difficult and requires expertise and appropriate facilities. Endoscopic therapy using either injection sclerotherapy or band ligation after adequate resuscitation and diagnostic endoscopy is the preferred first-line treatment. Bleeding not controlled by initial endoscopic therapy requires balloon tamponade followed by repeat variceal ligation or sclerotherapy. Patients who continue to bleed after endoscopic therapy are best treated with percutaneous radiological transjugular intrahepatic portosystemic shunt stent (TIPSS) insertion. After variceal eradication, patients require lifelong surveillance endoscopy and re-obliteration of varices by endoscopic therapy if they recur. Beta-blockers to prevent recurrent bleeding are reserved for selected patients. Patients with severe liver decompensation have a poor prognosis and should be evaluated for liver transplantation. Prophylactic endoscopic therapy in patients who have never bled from varices is contraindicated as it is associated with increased morbidity and mortality.

Gallstone pancreatitis--a critical review of current treatment strategies.

This review critically analyses the role of urgent biliary decompression in the management of acute gallstone pancreatitis with the emphasis on endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (ES). In an analysis of currently available prospective randomised trials the role of routine urgent ERCP with or without ES in patients with predicted severe pancreatitis is challenged. Patients with persistent biliary obstruction and associated cholangitis appear to be the only subgroup who may benefit from urgent biliary intervention.

Laparoscopic cardiomyotomy for achalasia after failed balloon dilatation.

BACKGROUND: This study was designed to determine the feasibility and outcome of laparoscopic cardiomyotomy in patients with achalasia who have persistent or recurrent dysphagia following balloon dilatation. METHODS: Ten patients who had undergone a minimum of two (range, two to seven) previous balloon dilatations underwent a single anterior cardiomyotomy extending from the gastroesophageal junction onto the esophagus proximally for 6 cm. Four patients had a Toupet fundoplication. Patients were analyzed using pre- and postoperative DeMeester symptom scores for dysphagia, regurgitation, and heartburn (0 = none-3 = maximal) and esophageal manometry. RESULTS: Mean operating time was 90 min. Periesophagitis was noted in some patients but was rarely troublesome. Submucosal fibrosis was present in all patients and made dissection more difficult particularly around the cardioesophageal junction. As a result, three patients had mucosal perforations that required repair by laparoscopic suturing. There were no subsequent postoperative complications. Median (IQR) postoperative stay was 3 (2-4) days. At 3-month reassessment, there was a reduction in the median dysphagia score from 3 to 0, and also in the regurgitation score from 3 to 0. At last follow-up (median, 22 months), one patient had developed recurrent dysphagia (grade 2), which improved with dilatation. Overall success of the laparoscopic procedure was therefore 90%. Only one patient developed new symptoms of reflux (mild, grade 1) after surgery. CONCLUSIONS: Laparoscopic cardiomyotomy provides good control of the symptoms of dysphagia and regurgitation without the morbidity of a laparotomy or thoracotomy incision. Although technically more difficult, the technique can be extended to those who have had previous balloon dilatation with complication and success rates similar to published results in patients who have not undergone previous dilatation.

Endoscopic balloon dilatation of peptic pyloroduodenal strictures.

A through-the-scope endoscopic balloon dilatation technique and acid-reducing medication was used in 46 consecutive patients (median age, 55; range, 21-88 years) with benign gastric outlet obstruction. In five patients, dilatation was not technically possible. In 41 patients, 122 dilatations (median, 2; range, 1-9 per patient) were performed without morbidity. Ninety-four procedures were successful (77%) at the initial attempt (able to pass a 12-mm endoscope into the duodenum at the end of the procedure). Median follow-up in the 41 patients was 19 (range, 1-78) months. Thirteen patients (32%) required subsequent surgery; 8 had delayed operation for persistent symptoms (1-28 months after the first dilatation), 1 had surgery during the initial hospital admission, and 4 required emergency surgery for other ulcer complications (3 perforation, 1 bleeding). Of the 28 patients who had only balloon dilatation and medical therapy, 11 are asymptomatic (4 with active ulceration), 9 have mild symptoms (Visick 2), and 3 have persistent symptoms (Visick 3). One patient was lost to follow-up and four patients have died (one from an ulcer-related complication). Balloon dilatation and sustained acid-reducing therapy with regular endoscopic surveillance should be first-line treatment of peptic pyloroduodenal strictures, because the procedure is safe and is likely to be successful in half of the patients in whom dilatation is technically possible.

Long term outcome of endoscopic drainage of pancreatic pseudocysts.

OBJECTIVE: Nonoperative drainage either by the percutaneous or endoscopic route has become a viable alternative to surgical drainage of pancreatic pseudocysts. Endoscopic drainage has been reported in a few small series with encouraging short term results. The aim of this study was to determine the indications, suitability, and long term outcome of transmural endoscopic drainage procedures. METHODS: All patients presenting over a 2-yr period to a tertiary referral hepatobiliary unit with pancreatic pseudocysts were studied. Endoscopic drainage was performed in patients with pseudocysts bulging into the stomach or duodenal lumen. Outcome measures were successful drainage of the pseudocyst, complications, and recurrence rates. RESULTS: Of 66 patients presenting with pseudocysts, 34 were considered suitable for endoscopic drainage. Twenty-four (71%) were successfully drained. Failures were associated with thick walled pseudocysts (> 1 cm), location in the tail of the pancreas, and pseudocysts associated with acute necrotizing pancreatitis. There were three recurrences (7%), two of which were successfully redrained endoscopically. The long term success rate (median follow-up, 46 months) of the initial procedure was 62%. CONCLUSION: Transmural endoscopic drainage is a safe procedure with minimal complications. It should be the procedure of choice for pseudocysts associated with chronic pancreatitis or trauma, with a wall thickness of < 1 cm and a visible bulge into the gastrointestinal lumen. Forty percent of pseudocysts fulfilled these criteria in our study.

Bouveret's syndrome complicated by acute pancreatitis.

BACKGROUND/AIM: This study evaluated a case of Bouveret's syndrome due to a cholecystoduodenal fistula and gallstone obstruction of the duodenum, complicated by acute pancreatitis and cholecystitis. METHODS: The presenting features, special investigations, radiological findings, operative and endoscopic procedures were reviewed. RESULTS: Symptoms persisted after laparotomy and removal of a gallstone in the duodenum. Intra-operative endoscopy identified a second previously undetected stone impacted in the distal duodenum. CONCLUSION: The importance of excluding more than one stone causing Bouveret's syndrome is emphasized.

Pancreaticoduodenectomy of ampullary carcinoma.

Thirty-two consecutive patients with adenocarcinoma of the ampulla of Vater who had curative resection by pancreaticoduodenectomy were analyzed to determine the accuracy of preoperative investigations and factors that influenced survival. Obstructive jaundice was present in 31 patients, and most patients had pain and weight loss. Ultrasound was more useful than CT in identifying biliary obstruction, whereas CT was more accurate in demonstrating pancreatic duct dilatation and an ampullary mass. Endoscopic retrograde cholangiopancreatography with biopsy and brush cytology was the most accurate investigation and proved or was suspicious of carcinoma in all patients. Nineteen patients had postoperative complications, three of whom died (9.4%)-two of sepsis and one from aspiration following hematemesis. Actuarial 5-year survival was 46 per cent. Stage of disease was the strongest predictor of survival. All patients with T1 lesions are alive more than 5 years after resection. Patients with lymph node metastases had a significantly shorter survival than node-negative patients (P = 0.00087). Pancreaticoduodenectomy is advocated for ampullary carcinoma in good-risk patients, with the anticipation of prolonged survival in those with early (T1) lesions and node-negative disease.
