Laparoscopic gastric bypass versus laparoscopic sleeve gastrectomy: A retrospective multicenter comparison between early and long-term post-operative outcomes.

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are the most commonly performed procedures for morbid obesity.

Methods: We performed a retrospective review of patients undergoing LRYGB or LSG between August 2000 and November 2014.

Results: Data from 581 (280 LSG and 301 LRYGB) were gathered.

Symptomatic annular pancreas in adult: Report of two different presentations and treatments and review of the literature.

Annular pancreas (AP) in adults is a rare embryologic abnormality detected after development of complications or as incidental finding. Diagnosis and treatment strategies for symptomatic adult AP remain controversial. We describe two different presentation of AP: a woman with a specific upper abdominal pain treated with medical therapy and a man with upper gastroenteric obstructive symptoms which underwent surgical duodeno-jejunal by-pass.

Laparoscopic circular stapled longitudinal extramucosal pyloroplasty: an alternative technique for pyloric disruption.

Objectives: Oesophagectomy with gastric pull-up is the most common surgical procedure for oesophageal cancer. Pyloroplasty may be performed to facilitate stomach emptying, but its role is still controversial. When laparoscopic mobilization of the stomach is performed, conventional extramucosal pyloroplasty may be difficult to carry out; therefore, we describe a new technique for mechanical pyloric disruption.

Is robot-assisted laparoscopic right colectomy more effective than the conventional laparoscopic procedure? A meta-analysis of short-term outcomes.

Aim: The use of robotic technology procedures has proved to be safe and effective, arising as a helpful alternative to standard laparoscopic surgery in a variety of colorectal procedures. However, the role of robotic assistance in laparoscopic right colectomy is still not demonstrated.

Methods: A systematic review of the literature was carried out performing an unrestricted search in MEDLINE, EMBASE, the Cochrane Library and Google Scholar up to 30th August 2014.

Left colon acute diverticulitis: an update on diagnosis, treatment and prevention.

Diverticulosis of the colon is a common disease with an increasing incidence in Western Countries. It represents a significant burden for National Health Systems in terms of costs. Most people with diverticulosis remain asymptomatic, about one quarter of them will develop an episode of symptomatic diverticular disease and up to 5% an episode of acute diverticulitis (AD).

Schwannoma of the colon: A case report.

Schwannomas are rare tumors originating from the Schwann cells, which form the neural sheath. These tumors occur most frequently in the head, neck, arms and limbs. Primary schwannomas of the colon and rectum are extremely rare; they are usually benign, but in extremely rare cases (2%), they can present with malignant degeneration if not surgically removed.

Pancreatico-jejunal anastomosis with invaginating jenunal "J"-loop. Preliminary report of a new technique.

Introduction: The pancreatic anastomosis is the most demanding step after pancreaticoduodenectomy (PD) and the pancreatic fistula (PF) is the most dreaded complication. Many techniques have been investigated to assess the best way to deal with the pancreatic stump after PD and none of these has shown to be superior in terms of statistically significant reduction of PF rate. We report the preliminary experience of a new technique of pancreaticojejunostomy (PJ).

A randomized study on 1-week versus 4-week prophylaxis for venous thromboembolism after laparoscopic surgery for colorectal cancer.

Objective: To compare the efficacy and safety of antithrombotic prophylaxis given for 1 week or 4 weeks in patients undergoing laparoscopic surgery for colorectal cancer.

Background: Extending antithrombotic prophylaxis beyond 1 week reduces the incidence of venous thromboembolism (VTE) after open abdominal surgery for cancer.

Methods: In consecutive patients who underwent laparoscopic surgery for colorectal cancer, complete compression ultrasonography of the lower limbs was performed after 8 ± 2 days of antithrombotic prophylaxis.

Closed hemorrhoidectomy with linear stapler: a consecutive series of 300 patients.

Background: Hemorrhoidectomy is one of the most commonly performed anorectal operations. The aim of this study was to evaluate the safety and the efficacy of a new technique for sutured closed hemorroidectomy with linear stapler in a consecutive series of 300 patients.

Patients And Methods: Between January 2006 and December 2009, 300 patients (117 male, 183 female) (mean age, 52 (range 21-85) years) with grade III and IV hemorrhoids were treated with our modified technique with linear stapler with 6 cm vascular recharge.
