Stricture Rate after Laparoscopic Roux-en-Y Gastric Bypass with a 21-mm Circular Stapler versus a 25-mm Linear Stapler.

Obesity is estimated to affect more than one and a half billion adults. Laparoscopic Roux-en-Y gastric bypass (LRYGB) has become one of the preferred weight loss procedures. However, complications can occur.

The efficacy of prophylactic IVC filters in gastric bypass surgery.

Background: Patients undergoing gastric bypass surgery have a high risk for thromboembolic events. Over the last decade, the use of prophylactic IVC filters (IVCF) has drastically increased for patients who are considered high risk. However, the role and efficacy of prophylactic IVCF placement remain controversial, and the literature is limited to a few retrospective studies.

Pneumoperitoneum after virtual colonoscopy: causes, risk factors, and management.

Computed tomographic virtual colonoscopy (CTVC) is a safe and minimally invasive modality when compared with fiberoptic colonoscopy for evaluating the colon and rectum. We have reviewed the risks for colonic perforation by investigating the relevant literature. The objectives of this study were to assess the risk of colonic perforation during CTVC, describe risk factors, evaluate ways to reduce the incidence complications, and to review management and treatment options.

The first reported case of ureteral perforation in a patient with severe toxic epidermal necrolysis syndrome.

The aim of this study was to briefly review toxic epidermal necrolysis syndrome (TENS) and Steven Johnson Syndrome (SJS), as well as describe the unique complication of ureteral perforation. A case of ureteral perforation in an 18-year old woman with TENS was documented and reviewed. In addition to studying this unusual presentation the authors have also provided a brief review of TENS and SJS along with several common complications of this disease process.

The 100-year evolution of the isolated internal iliac artery aneurysm.

Background: Isolated internal iliac artery aneurysms (IIIAA) are a rare form of aneurysm. The incidence increases with age, and the prevalence is higher in men. The clinical presentation can vary, and standard treatment protocols are not established.

A unique case of unilateral lower extremity sparing systemic peripheral gangrene.

We present here the case of a 70-year-old female who developed a systemic peripheral gangrene in both of her upper extremities (all fingers) and her right foot due to a severe septic shock requiring a systemic vasopressor therapy. Interestingly, the patient's left foot remained spared from gangrenous changes possibly due to a chronic external iliac artery occlusion and thus the lower concentration of vasopressors in that extremity.
