A Case Report of Intussusception After Gastric Bypass.

Intussusception is a rare cause of late complication after gastric bypass. We report the case of a 53-year-old woman having a gastric bypass in 2011. The patient presented to the emergency department with abdominal pain and vomiting.

Pneumoscrotum, pneumomediastinum, pneumothorax, and pneumorrhachis following colon surgery.

We report the case of an 80-year-old man who developed a colocutaneous fistula as a complication of anastomotic leakage following segmental colonic resection. The patient presented with an abscess of the abdominal wall, subcutaneous emphysema, pneumomediastinum, pneumothorax, pneumorrhachis, and pneumoscrotum. We discuss the possible mechanisms for these unusual clinical presentations of extraperitoneal air following anastomotic leak.

Role of laparoscopy in the management of visceral injuries following abdominal stab wounds.

Background: Laparoscopy offers several advantages in the treatment of abdominal stab wounds. In this paper, we report our experience during 2004, where hemodynamically stable patients with stab wounds were managed laparoscopically.

Patients And Methods: Between January and December 2004, 8 hemodynamically stable patients (7 men, 1 woman) underwent laparoscopy for anterior abdominal stab wounds.

Accuracy of MDCT in predicting site of gastrointestinal tract perforation.

Objective: The purpose of this study was to prospectively evaluate the accuracy of MDCT for preoperative determination of the site of surgically proven gastrointestinal tract perforations and to determine the most predictive findings in this diagnosis.

Subjects And Methods: We prospectively studied 85 consecutive patients with extraluminal air on MDCT who had surgically proven gastrointestinal tract perforations. All patients underwent surgery within 12 hours after MDCT was performed.

Intragastric band erosion after laparoscopic adjustable gastric banding for morbid obesity: imaging characteristics of an underreported complication.

Objective: Our purpose was to describe the imaging findings of intragastric band erosion, an underreported complication after laparoscopic adjustable gastric banding for the treatment of morbid obesity. In this long-term complication, the gastric band fastened around the upper stomach to create a small proximal gastric pouch gradually erodes into the stomach wall and can extend into the gastric lumen. We present three cases of patients with band erosion in whom findings on an upper gastrointestinal series and CT established the diagnosis.

Intrathoracic migration of the wrap after laparoscopic Nissen fundoplication: radiologic evaluation.

Objective: The purpose of our study was to evaluate the different types of postoperative herniation of the wrap into the thorax after laparoscopic Nissen fundoplication, to propose a clear radiologic definition, and to establish their respective frequencies.

Subjects And Methods: Two hundred twenty-six consecutive patients who underwent laparoscopic Nissen fundoplication were studied prospectively. All patients underwent an upper gastrointestinal series before surgery and on the first postoperative day.
