Littoral cell angioma of the spleen: case report and literature review.

Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging.

Estrogen and progesterone receptors in endometriosis.

Background: This study aims to identify the presence of estrogen and progesterone hormone receptors in endometriosis implants and to determine whether hormone treatment influences the receptors in these implants.

Methods: Cross-sectional study with historical data collection. The analysis was conducted on 156 endometriosis implants from 67 patients undergoing endometriosis laparoscopy.

[Not Available].

Background: Bariatric surgery is considered the best treatment option for patients with obesity who are classed as high risk for thromboembolic events.

Objectives: To compare two different doses of low weight molecular heparin (LWMH) for prevention of deep venous thrombosis (DVT) in candidates for bariatric surgery, in terms of DVT risk, abnormal anti-Xa levels, and preoperative and/or postoperative bleeding.

Methods: A cross-sectional comparative study of bariatric surgery patients divided into two groups given different doses of LWMH; 40 mg of LWMH (control group, CG) and 80 mg of LWMH (study group, SG), both evaluated by vascular ultrasonography (VU) and according to the results of PTT, PT, platelets, and anti-Xa factor assays.

Efficacy of Utilizing Argon Plasma Coagulation for Weight Regain in Roux-en-Y Gastric Bypass Patients: a Multi-center Study.

Background: Endoscopic approaches exist for targeting weight regain after Roux-en-Y gastric bypass (RYGB), including endoscopic suturing, clipping, and sclerotherapy. Argon plasma coagulation (APC) is a noncontact electrocoagulation method, and when used in RYGB patients, it has shown reduction in the diameter of the gastrojejunal anastomosis.

Objectives: To study the effectiveness of APC for weight regain in terms of weight loss for RYGB patients, from eight bariatric centers.

ALTERNATIVE TECHNIQUE FOR CHOLECYSTECTOMY COMPARABLE TO SINGLE PORT.

Background: With the advancement of laparoscopic surgery, new techniques have been proposed and disseminated in order to reduce the surgical aggression and get better cosmetic results.

Aim: To present alternative technique for videocholecystectomy comparable to single port technique using conventional material for laparoscopic surgery.

Method: Introduction of laparoscopic devices using two incisions; gallbladder traction with thread, exposition of Calot triangle, and ligature of cystic pedicle with polymer clips.

Post-bariatric surgery weight regain: evaluation of nutritional profile of candidate patients for endoscopic argon plasma coagulation.

Background: Bariatric surgery is effective treatment for weight loss, but demand continuous nutritional care and physical activity. They regain weight happens with inadequate diets, physical inactivity and high alcohol consumption.

Aim: To investigate in patients undergoing Roux-Y-of gastroplasty weight regain, nutritional deficiencies, candidates for the treatment with endoscopic argon plasma, the diameter of the gastrojejunostomy and the size of the gastric pouch at the time of treatment with plasma.

Endoscopic plasma argon coagulation in treatment of weight regain after bariatric surgery: what does the patient think about this?

Background: Bariatric surgery, especially Roux-en-Y gastric bypass is an effective treatment for refractory morbid obesity, causing the loss of 75% of initial excess weight. After the surgery, however, weight regain can occur in 10-20% of cases. To help, endoscopic argon plasma coagulation (APC) is used to reduce the anastomotic diameter.

[Deep infiltrating endometriosis: anatomical distribution and surgical treatment].

Purpose: To evaluate the anatomical distribution of deep infiltrating endometriosis (DIE) lesions in a sample of women from the South of Brazil.

Methods: A prospective study was conducted on women undergoing surgical treatment for DIE from January 2010 to January 2012. The lesions were classified according to eight main locations, from least serious to worst: round ligament, anterior uterine serosa/vesicouterine peitoneal reflection, utero-sacral ligament, retrocervical area, vagina, bladder, intestine, ureter.
