Computed tomography findings of internal hernia after gastric bypass that may precede small bowel obstruction.

Purpose: This study evaluates computed tomography signs of internal hernia in gastric bypass patients, including several previously unreported signs suggestive of internal hernia.

Methods: Eighteen patients with surgically proven internal hernia were included in the study cohort. The signs analyzed included the mesenteric swirl, hurricane eye, mushroom sign, and dilated small bowel loops, as well as previously non-investigated signs such as bowel wall edema, engorged mesenteric vessels, engorged mesenteric lymph nodes, and hazy mesenteric fat.

Nongynecological endometriosis presenting as an acute abdomen.

Patients commonly present with pelvic pain or infertility, although the range of clinical symptoms varies widely. Affected women may be asymptomatic or experience mild, moderate, or severe pain that fluctuates with hormonal cycles.

Internal hernia complications of gastric bypass surgery in the acute setting: spectrum of imaging findings.

Bariatric surgery is increasingly becoming an option for the treatment of morbid obesity. Patients who have undergone gastric bypass surgery have varied post-surgical complications which present acutely in the emergency medical setting, particularly internal hernias. It may be difficult to identify an internal hernia in the absence of intestinal obstruction.

Cost-effectiveness and patient tolerance of low-attenuation oral contrast material: milk versus VoLumen.

Objective: The purpose of our study was to prospectively compare the cost, effectiveness, and patient tolerance of milk and VoLumen, a 0.1% barium suspension, in patients undergoing abdominal and pelvic CT with oral and i.v.
