Giant gastric lipossarcoma: case report and review of the literature.

Liposarcoma is one of the most common soft tissue sarcomas in adults, occurring in 15 to 20% of all patients with sarcoma. Primary liposarcoma of the stomach is rare. We report a case of patient with giant gastric liposarcoma who underwent surgery after a gastrointestinal bleeding.

Ethyl-pyruvate reduces lung injury matrix metalloproteinases and cytokines and improves survival in experimental model of severe acute pancreatitis.

Purpose: To investigate if the ethyl-pyruvate solution could reduce mortality in AP and/or diminish the acute lung injury.

Methods: Forty male rats, weighing between 270 to 330 grams were operated. An experimental model of severe AP by injection of 0.

Endoscopic treatment of bleeding gastric varices using large amount of N-butyl-2-cyanoacrylate under fluoroscopic guidance.

Purpose: We propose the use of fluoroscopic guidance for endoscopic injection of n-butyl-2-cyanoacrylate to treat gastric variceal hemorrhage to achieve placement of the safest quantity of tissue adhesive.

Methods: Ten patients with gastric varices were treated with n-butyl-2-cyanoacrylate endoscopic injection under fluoroscopic guidance for the purpose of hemostasis or prevention of recurrent bleeding. The glue was infused into the varices in the quantities needed to achieve complete obliteration of the gastric varices.

Laparoscopic evaluation of abdominal adhesions with different prosthetic meshes in rabbits.

Background: The use of prosthetic materials to reinforce the abdominal wall is associated with a low index of recurrence; however, intraperitoneal placement of a foreign body may lead to adhesions. The present investigation was designed to determine adhesion formation with commercially available meshes implanted laparoscopically in rabbits.

Methods: Three different meshes were implanted laparoscopically in 24 rabbits: polypropylene (mesh A), polypropylene and sodium hyaluronate-carboxymethylcellulose (mesh B), and polypropylene and expanded polytetrafluoroethylene (mesh C).

Randomized trial of total fundoplication and fundal mobilization with or without division of short gastric vessels: a short-term clinical evaluation.

Purpose: Evaluate short results after fundoplication procedure, concerning the division of short gastric vessels.

Methods: A prospective randomization of 90 patients with indication for hiatoplasty and total fundoplication with fundus mobilization was performed. They were divided into two groups: no SGV division (group A, n= 46) and with SGV division (Group B, n=44), although in both groups the gastric fundus was mobilized to perform a floppy valve.

Experimental model of severe acute pancreatitis in rabbits.

Purpose: To develop an experimental model of severe acute pancreatitis in rabbits through a pancreatic ductal injection of sodium taurocholate.

Methods: Twenty-four albino rabbits of the New Zealand lineage were distributed into four groups of six animals (A, B, C and S). The rabbits of three experimental groups (A, B and C) were submitted to a laparatomy and received a pancreatic ductal injection of 1 ml/kg sodium taurocholate 5%.

Laparoscopic management of hepatic cysts.

The present study describes the technique and evaluation of postsurgical results, hospital stay, and follow-up of patients who underwent hepatic cyst surgical treatment by laparoscopic access. Twelve patients presenting liver cystic disease were included in this research. Clinical conditions, laboratorial and radiologic examinations, surgical technique, complications, and postoperative follow-up were discussed.

Comparative study of inflammatory response and adhesions formation after fixation of different meshes for inguinal hernia repair in rabbits.

Purpose: Compare, in a rabbit model, the inflammatory response and adhesions formation following surgical fixation of polypropilene and Vypro mesh in the inguinal preperitoneal space.

Methods: Fourteen male New Zealand rabbits, weighing between 2.000 to 2.

Obesity and symptomatic achalasia.

Weight loss is a frequent finding in achalasia because of the difficulty in swallowing. Although manometric findings compatible with achalasia have been found in morbidly obese patients, all of them were asymptomatic. The authors report a case of symptomatic achalasia and morbid obesity in a 38-year-old woman.
