Endoscopic transgastric procedures in anesthetized pigs: technical challenges, complications, and survival.

Background And Study Aims: An incisionless endoscopic peroral transgastric approach to the peritoneal cavity has shown promise in animals as a potentially less invasive form of surgery. We present our experience with various endoscopic peroral transgastric procedures, reporting on the technical aspects and challenges that arose.

Materials And Methods: The following procedures were performed in 10 anesthetized pigs using a double-channel endoscope: peritoneoscopy (10 pigs), liver biopsy (one pig), cholecystectomy (six pigs), fallopian tube excision (one pig), and hysterectomy (one pig).

Delayed presentation of ilio-iliac arteriovenous fistula following laparoscopic cholecystectomy treated with percutaneous graft-covered stent placement.

Major vascular injuries during laparoscopic cholecystectomy are rare, usually readily apparent, and immediately treated. We report a case of delayed presentation of a retroperitoneal vascular injury. The patient presented with abdominal pain and increasing edema of the lower extremities 1 year after laparoscopic cholecystectomy and was found to have an ilio-iliac arteriovenous fistula.

Elucidation of cytomegalovirus disease recurrence in an HIV-1-positive patient.

Background: Cytomegalovirus (CMV) is responsible for the most common opportunistic viral infection in patients with acquired immunodeficiency syndrome (AIDS). The colon is a common site for CMV infection in patients positive for the human immunodeficiency virus (HIV). The clinical diagnosis of CMV infection is based on the characteristic endoscopic appearance of extensive ulceration of the gastric mucosa.

Plexiglas (polymethylmethacrylate) implantation: technique, pre-clinical and clinical experience.

Over the past few decades, a great scientific effort has been made to treat gastroesophageal reflux disease (GERD). This reflects a trend in modem medicine toward optimizing quality of life, reducing health-related lost working hours, and minimizing costs of chronic treatments. It also reflects a revived interest in diseases that can be studied using novel equipment and that can be cured using minimally invasive techniques.

Implantation of microballoons in the management of fecal incontinence.

Purpose: The implantation of expandable microballoons has proved successful for the treatment of stress urinary incontinence. This led us to test its effectiveness in the treatment of severe fecal incontinence.

Methods: Six patients (four male), of average age of 43 (range, 29-60) years, with severe fecal incontinence, underwent implantation of expandable microballoons in the submucosa of the anal canal.
