Background and Objectives Internal hernia (IH) after gastric bypass can be a life-threatening complication. Obstruction presents acutely or as chronic relapses, with symptoms of abdominal pain, nausea, and vomiting. Early detection and exploration of IH as the cause of small bowel obstruction (SBO) is critical in this surgical emergency and can reduce morbidity and mortality. We conducted a ret...

conclusions the findings of this study indicate that oral pregabalin (300 mg dose) can alleviate patients’ pain and nausea/vomiting and notably reduce adverse effects. results a total of 60 patients were compared; 30 patients in each of the pregabalin and control groups. both groups were similar in age and sex distribution. mean pain intensity levels during the whole follow up were lower in the...

Today, bariatric surgery, as the only effective therapy for morbid obesity, is expanding exponentially to meet the global epidemic of obesity. There is increasing evidence that effective long-term weight loss is achieved after bariatric surgery. A substantial majority of patients with diabetes, hyperlipidemia, hypertension and obstructive sleep apnea have experienced complete resolution or impr...

As the incidence of obesity increases, laparoscopic Roux-en-Y gastric bypass (REYGB) surgery has become a surgical option for many patients. Although the laparoscopic Roux-en Y procedure has been shown to reduce weight and improve diabetes, hyperlipidemia, hypertension and sleep apnea, it is not without significant risks, as more than 10% of patients who undergo this procedure have postoperativ...

Laparoscopic mini-gastric bypass surgery is a safe and simple surgical intervention for treating morbid obesity and diabetes mellitus and is now being performed more frequently. Radiologists must be critical in their postoperative evaluation of these patients. In this pictorial review, we explain and illustrate the surgical technique, normal postoperative anatomy, and associated complications a...

Postoperative hypoxemia can be a challenging diagnostic and management dilemma for the clinician. We present here a case of postoperative hypoxemia following laparoscopic gastric bypass surgery secondary to presumed pulmonary embolism complicated with a patent foramen ovale. The diagnostic pitfalls associated with a negative spiral computed tomography scan and the impact of coexisting medical c...

We report a rare case of complicated jejunal diverticulitis in a patient with previous bariatric surgery. Small bowel diverticulosis is generally considered an inoffensive disease. In this report we describe a case of small bowel perforation in an obese subject who had undergone laparoscopic Roux-en-Y gastric bypass.

BACKGROUND Currently, bariatric surgery is the most effective therapy for morbid obesity, and the laparoscopic approach is considered gold-standard for Roux-en-Y gastric bypass. Totally robotic Roux-en-Y gastric bypass has been proposed as a major evolution in minimally invasive bariatric surgery and its use is becoming more widespread. AIM To provide an early report of the first Brazilian ca...

BACKGROUND To review our experience with early jejunojejunostomy obstruction (JJO) at a large academic teaching hospital and provide a management algorithm. Early JJO is a known and often overlooked complication of laparoscopic Roux-en-Y gastric bypass. METHODS From 2003 to 2007, 1097 patients underwent laparoscopic Roux-en-Y gastric bypass at our institution. Data, including patient demograp...

OBJECTIVES Laparoscopic aortobifemoral bypass has become an established treatment option for symptomatic aortoiliac obstructive disease at dedicated centers. Minimally invasive surgical techniques like laparoscopic surgery have often been shown to reduce expenses and increase patients' health-related quality of life. The main objective of our study was to measure quality-adjusted life years (QA...
