Comparison of intra-abdominal abscess formation after laparoscopic and open appendectomy for complicated and uncomplicated appendicitis: a retrospective study.

Introduction: Acute appendicitis (AA) is one of the most common causes of acute abdominal pain seen in emergency departments and appendectomy has been the preferred treatment of this disease for decades. Postoperative intra-abdominal abscess (PIAA) complicates 3% to 25% of appendectomies and the risk is highest following complicated appendicitis. However, the risk for intra-abdominal abscess formation after appendectomy is still a matter of debate.

Outcomes of percutaneous cholecystostomy in elderly patients: a systematic review and meta-analysis.

Introduction: Percutaneous cholecystostomy (PC) represents a management option to control sepsis in patients with acute cholecystitis, who are unable to tolerate surgery.

Aim: This review aimed to evaluate the outcomes of elderly patients treated with PC and compare it with emergent cholecystectomy.

Material And Methods: An electronic search of the Embase, Medline Web of Science, and Cochrane databases was performed.

Bariatric surgery: blessing or sometimes curse for the liver?

Introduction: Nowadays morbid obesity has become a worldwide health issue and the use of bariatric surgery undoubtedly results not only in weight reduction but also in the improvement of comorbidities. Although bariatric surgery is the optimal choice for metabolic syndrome resolution and hepatic function improvement, there is evidence that in rare cases it may lead to aggressive steatohepatitis, acute liver failure, fibrosis, and deterioration of the overall prognosis, without having fully understood the underlying pathophysiological mechanisms.

Case Report: In this case report we present a 45-year-old female patient with morbid obesity, body mass index 80, who underwent long-limb Roux en Y gastric bypass (LL-RYGB) and was admitted to the emergency department with jaundice and impaired liver function laboratory tests on postoperative day 90.

Laparoscopic removal of a fishbone migrating from the gastrointestinal tract to the pancreas.

Laparoscopic surgery can be performed safely for the removal of a foreign body embedded in the pancreas and should be preferred instead of open surgery, whenever possible.

Intra-arterial thrombolysis within three hours of stroke onset in middle cerebral artery strokes.

Background And Purpose: The Prolyse in Acute Cerebral Thromboembolism II (PROACT II) trial showed improved outcomes in patients with proximal middle cerebral artery (MCA) occlusions treated with intra-arterial (IA) thrombolysis within 6 h of stroke onset. We analyzed outcomes of patients with proximal MCA occlusions treated within 3 h of stroke onset in order to determine the influence of time-to-treatment on clinical and angiographic outcomes in patients receiving IA thrombolysis.

Methods: Thirty-five patients from three academic institutions with angiographically demonstrated proximal MCA occlusions were treated with IA thrombolytics within 3 h of stroke onset.

Angiographic assessment of pial collaterals as a prognostic indicator following intra-arterial thrombolysis for acute ischemic stroke.

Background And Purpose: This study examines whether anatomic extent of pial collateral formation documented on angiography during acute thromboembolic stroke predicts clinical outcome and infarct volume following intra-arterial thrombolysis, compared with other predictive factors.

Methods: Angiograms, CT scans, and clinical information were retrospectively reviewed in 65 consecutive patients who underwent thrombolysis for acute ischemic stroke. Clinical data included age, sex, time to treatment, National Institutes of Health Stroke Scale (NIHSS) score on presentation of symptoms, NIHSS score at the time of hospital discharge, and modified Rankin scale score at time of hospital discharge.
