Diagnostic accuracy of a fast MRI T2-sequence for the diagnosis of internal herniation after Roux-and-Y gastric bypass during pregnancy: A retrospective single center study.

Purpose: The objective of this retrospective study was to evaluate the diagnostic accuracy of a fast sequence Magnetic Resonance Imaging (MRI) sequence, T2- half-Fourier acquisition single-shot turbo spin echo (HASTE) for the diagnosis of internal herniation (IH) in pregnant patients with a history of Roux-en-Y gastric bypass (RYGB).

Methods: Abdominal MRI studies, performed for the clinical suspicion of IH of pregnant patients with a history of RYGB, were analyzed by two abdominal radiologists. Thirty-one cases were included and for each case both readers independently evaluated the T2 HASTE sequence in different planes (axial, coronal and sagittal) to determine the presence or absence of IH.

A survey of European-African surgeons' management of common bile duct stones.

Background: Common bile duct (CBD) stones can be managed by either endoscopic retrograde cholangiopancreatography (ERCP) or laparoscopic common bile duct exploration (LCBDE). The aim of this survey was to document the management of CBD stones by European-African HPB Association (E-AHPBA) members.

Methods: All 331 members of the E-AHPBA were invited by personal email to participate to an online survey.

Attenuated atrial natriuretic peptide-mediated lipolysis in subcutaneous adipocytes of obese type 2 diabetic men.

Catecholamines and atrial natriuretic peptide (ANP) are major regulators of adipocyte lipolysis. Although obesity is characterized by catecholamine resistance in subcutaneous adipose tissue (SCAT), data on ANP lipolytic response and sensitivity in different adipose tissue (AT) depots of metabolically distinct humans are scarce. Ex vivo catecholamine- and ANP-induced lipolysis was investigated in adipocytes derived from SCAT and visceral AT (VAT) depot of lean (n=13) and obese men, with (n=11) or without (n=18) type 2 diabetes (HbA1c < or ≥ 6.

Pelvic actinomycosis: a malignant appearing mass. A case report.

Pelvic actinomycosis is a rare complication of a long-term intrauterine contraceptive device. Early diagnosis is important, as clinical and radiological imaging may mimic a malignant pathology and lead to radical and unnecessary surgery. We report a case of pelvic actinomycosis in a woman who had used an intrauterine contraceptive device for the last 13 years.

Rectal melanoma--a rare tumour.

Malignant rectal melanoma is a rare tumour. We report a case of a 66-year-old man who presented with a two-month history of rectal bleeding, pain, and tenesmus. A semicircular rectal tumour was seen, just above the dentate line.

Valvular colonic sphincter substitutes. An experimental study in dogs.

Three types of colonic sphincter substitutes were placed at an abdominal colostomy in dogs. Simple valve construction (8) was based on orthograde intussusception of the colon over 3.5 cm.
