Intestinal intussusception as a postoperative complication of gastric bypass.

The gold standard for bariatric surgery is the laparoscopic gastric bypass, which consists in forming a small gastric pouch and a Roux-en-Y anastomosis. We present the case of a 41-year-old female who underwent a laparoscopic gastric bypass 8 years prior to her admission to the emergency room, where she arrived complaining of severe and colicky epigastric abdominal pain. The abdominal computed tomography showed a jejuno-jejunal intussusception, for which the patient underwent urgent exploratory laparotomy with intussusception reduction.

Robotic-assisted sigmoidectomy with intracorporeal anastomosis and endoscopic management of deep infiltrating intestinal endometriosis.

Deep endometriosis, defined as external adenomyosis, is a late stage of endometriosis. Associated with very severe pain, in addition to probably being a cofactor of infertility, with a low prevalence, the diagnosis is integrated by high clinical suspicion and confirmed with imaging studies. Deep infiltration can reach sigmoid colon, which would have surgical indication as resolving treatment.

Performance of LDL-C calculated with Martin's formula compared to the Friedewald equation in familial combined hyperlipidemia.

Background And Aims: A novel method to estimate low density lipoprotein cholesterol (LDL-C) has been proposed by Martin et al. This may permit a more accurate estimation of cardiovascular risk, however, external validation is needed. Here, the performance of LDL-C using this new method (LDL-N) is compared with LDL-C estimated with Friedewald equation (LDL-F) in familial combined hyperlipidemia (FCHL), a common primary dyslipidemia in which apolipoprotein B containing particle composition is abnormal and interferes with LDL-C estimation.
