Successful endoscopic sclerotherapy for bleeding gastric varices with combined cyanoacrylate and aethoxysklerol

Two patients with liver cirrhosis and portal hyper-tension related to hepatitis infection were admitted to Shanghai Ruijin Hospital due to recurrent melena and hematemesis. Isolated gastric varices were observed in the gastric fundus during the retroflexion of gastroscope. We carried out endoscopic sclerotherapy successfully for bleeding gastric varices with combined cyanoacrylate and aethoxysklerol, which disappeared dramatically several months after two courses of sclerotherapy for each patient. No complication and clinical signs of gastrointestinal re-bleeding were observed during the 6-mo endoscopic follow-up. CT portal angiography (CTPA) has been widely used in the assessment of variceal treatment and improves the results of endoscopic injection therapy.

A primary intestinal lymphangiectasia patient diagnosed by capsule endoscopy and confirmed at surgery: A case report

Intestinal lymphangiectasia （IL） is a rare disease characterized by dilated lymphatic vessles in the intestinal wall and small bowel mesentery which induce loss of protein and lymphocytes into bowel lumen. Because it most often occurs in the intestine and cannot be detected by upper gastroendoscopy or colonoscopy, and the value of common image examinations such as X-ray and computerized tomography （CT） are limited, the diagnosis of IL is difficult, usually needing the help of surgery. Capsule endoscopy is useful in diagnosing intestinal diseases, such as IL. We here report a case of IL in a female patient who was admitted for the complaint of recurrent edema accompanied with diarrhea and abdominal pain over the last twenty years, and aggravated ten days ago. She was diagnosed by M2A capsule endoscopy as a primary IL and confirmed by surgical and pathological examination.

Acute esophageal necrosis caused by alcohol abuse

Acute esophageal necrosis (AEN) is extremely rare and the pathogenesis of this is still unknown. We report a case of AEN caused by alcohol abuse. In our case, the main pathogenesis could be accounted for low systemic perfusion caused by severe alcoholic lactic acidosis. After the healing of AEN, balloon dilatation was effective to manage the stricture.

Long-term results of graded pneumatic dilatation under endoscopic guidance in patients with primary esophageal achalasia

AIM:Achalasia is the best known primary motor disorder of the esophagus in which the lower esophageal sphincter (LES)has abnormally high resting pressure and incomplete relaxation with swallowing.Pneumatic dilatation remains the first choice of treatment.The aims of this study were to determine the long term clinical outcome of treating achatasia initially with pneumatic dilatation and usefulness of pneumatic dilatation technique under endoscopic observation without fluoroscopy. METHODS:A total of 65 dilatations were performed in 43 patients with achalasia[23 males and 20 females,the mean age was 43 years(range,19-73)].All patients underwent an initial dilatation by inflating a 30 mm balloon to 15 psi under endoscopic control.The need for subsequent dilatation was based on symptom assessment.A 3.5 cm balloon was used for repeat procedures. RESULTS:The 30 mm balloon achieved a satisfactory result in 24 patients(54%)and the 35 mm ballon in 78% of the remainder(14/18).Esophageal perforation as a short-term complication was observed in one patient(2.3%).The only late complication encountered was gastroesophageal reflux in 2(4%)patients with a good response to dilatation.The mean follow-up period was 2.4 years(6 mo-5 years).Of the patients studied,38(88%)were relieved of their symptoms after only one or two sessions.Five patients were referred for surgery(one for esophageal perforation and four for persistent or recurrent symptoms).Among the patients whose follow up information was available,the percentage of patients in remission was 79%(19/24)at 1 year and 54%(7/13)at 5 years. CONCLUSION:Performing balloon dilatation under endoscopic observation as an outpatient procedure is simple,safe and efficacious for treating patients with achalasia and referral of surgical myotomy should be considered for patients who do not respond to medical therapy or individuals that do not desire pneumatic dilatations.

Surgical risk for patients with Chagasic achalasia and its correlation with the degree of esophageai dilation

AIM： To analyze the risk of cardiovascular complications in patients with indication for surgical treatment of Chagasic esophageal achalasia and to correlate the surgical risks with the degree of esophageal dilation, thereby proposing a risk scale index. METHODS： One hundred and twenty-four patients with Chagasic esophageal achalasia, who received surgical treatment at the Hospital das Clinicas of the Federal University of Goiás, were included in this study. The patients were mostly related to the postoperative complications due to the cardiovascular system. All the patients were submitted to： （1） clinical history to define the cardiac functional class （New York Heart Association）; （2） conventional 12-lead electrocardiogram at rest; and （3） contrast imaging of the esophagus to determine esophageal dilatation according to Rezende＇s classification of Chagasic megaesophagus. RESULTS： An assessment of the functional classification （FC） of heart failure during the preoperative period determined that 67 patients （54.03%） were assigned functional class Ⅰ （FC Ⅰ）, 46 patients （37.09%） were assigned functional class Ⅱ （FC Ⅱ）, and 11 patients （8.87%） were assigned functional class Ⅲ （FC Ⅲ）. None of the patients were assigned to functional class Ⅳ （FC Ⅳ）. There was a positive correlation between the functional class and the postoperative complications （FC Ⅰ×FC Ⅱ： P〈0.001; FC Ⅰ×FC Ⅲ： P〈0.001）. The ECG was normal in 44 patients （35.48%） and presented abnormalities in 80 patients （64.52%）. There was a significant statistical correlation between abnormal ECG （arrhythmias and primary change in ventricular repolarization） and postoperative complications （P〈0.001）. With regard to the classification of the Chagasic esophageal achalasia, the following distribution was observed： group Ⅱ, 53 patients （42.74%）; group Ⅲ, 37 patients （29.83%）; and group Ⅳ, 34 patients （27.41%）. There was a positive correlation between the degree of esophageal dilation and the increase in postoperative complications （grade Ⅱ×grade Ⅲ achalasia： P〈0.001; grade Ⅱ×grade Ⅳ achalasia： P〈0.001; and grade Ⅲ×grade Ⅳ achalasia： P = 0.017）. Analyzing these results and using a multivariate regression analysis associated with the probability decision analysis, a risk scale was proposed as follows： up to 21 points （mild risk）; from 22 to 34 points （moderate risk）; and more than 34 points （high risk）. The scale had 82.4% accuracy for mild risk patients and up to 94.6% for the high risk cases. CONCLUSION： The preoperative evaluation of the cardiovascular system, through a careful anamnesis, an ECG and contrast imaging of the esophagus, makes possible to estimate the surgical risks for Chagas＇ disease patients who have to undergo surgical treatment for esophageal achalasia.

Redo pull-through in total colonic aganglionosis due to residual aganglionosis:a single center’s experience

Background Reoperation for total colonic aganglionosis(TCA)may be required for residual aganglionosis after an initial radical operation.We aimed to investigate the symptoms,management,and outcomes of patients who required a redo pullthrough(Redo PT).Methods Nine TCA patients underwent Redo PT at our center between 2007 and 2017.Their medical records were reviewed.Parental telephone interviews that included disease-specific clinical outcomes were conducted,and post-operative complications and long-termoutcomes(including height-for-age/weight-for-age and bowel-function score)were compared to those of single-pull-through(Single PT)patients(n=21).Results All the nine Redo PT patients suffered obstruction within 1 month after the initial operation that could not be alleviated by conservative treatment.All abdominal X-ray/contrast barium enemas showed proximal bowel dilatation,indicating residual aganglionosis.The median ages at the initial operation and Redo PT were 200 and 509 days,respectively.Reoperation consisted of an intraoperative frozen biopsy and a modified laparotomic Soave procedure in all patients.Postoperative complications included perianal excoriation(n=3),intestinal obstruction(n=2),enterocolitis(n=2),and rectovestibular fistula(n=1).Seven Redo PT patients were followed up for a mean time of 7.162.3 years;six(85.7%)had good growth and four(57.1%)had good bowel-function recovery.Post-operative complications and long-term outcomes were almost equal between the Redo PT and Single PT groups(all P>0.05).Conclusion TCA patients with recurrent obstructive symptoms and dilated proximal bowel may have residual aganglionosis after an initial operation.Redo PT is effective and provides good long-termoutcomes comparable to those of patients who benefited from Single PT.
