Materials And Methods: This study was a prospective and randomized clinical trial. Forty obese patients were randomized into two groups: gastric bypass with 3D imaging system or with conventional 2D system.

A Four-step Technique for Effluent Diversion of Enteroatmospheric Fistulas.

Background: Isolation of the enteroatmospheric fistula (EAF) opening and prevention of contamination of the rest of the wound by effluent are important factors in the management of EAF.

Objective: The aim of this study is to describe an easily reproducible technique for effluent control in patients with EAF.

Materials And Methods: A retrospective analysis was conducted on all patients who underwent the present technique between 2013 and 2015.

Methods: A systematic search was undertaken using PubMed, Embase, Cochrane, and Web of Science.

A New Era of Bile Duct Repair: Robotic-Assisted Versus Laparoscopic Hepaticojejunostomy.

Background: Despite scientific evidence of the safety, efficacy, and in some cases superiority of minimally invasive surgery in hepato-pancreato-biliary procedures, there are scarce publications about bile duct repairs. The aim of this study was to compare the outcomes of robotic-assisted surgery versus laparoscopic surgery on bile duct repair in patients with post-cholecystectomy bile duct injury.

Methods: This is a retrospective comparative study of our prospectively collected database of patients with bile duct injury who underwent robotic or laparoscopic hepaticojejunostomy.

Enhanced recovery after surgery protocol allows ambulatory laparoscopic appendectomy in uncomplicated acute appendicitis: a prospective, randomized trial.

Background: Previous observational studies have demonstrated the safety of discharging patients after laparoscopic appendectomy within the same day without hospitalization. The application of Enhanced Recovery After Surgery (ERAS) guidelines has resulted in shorter length of stay, fewer complications, and reduction in medical costs. The aim of this study was to investigate if ERAS protocol implementation in patients with acute uncomplicated appendicitis decreases the length of stay enough to allow for ambulatory laparoscopic appendectomy.

Robotic-assisted Roux-en-Y hepaticojejunostomy after bile duct injury.

Background: The Da Vinci Robotic Surgical System has positioned itself as a tool that improves the ergonomics of the surgeon, facilitating dissection in confined spaces and enhancing the surgeon's skills. The technical aspects for successful bile duct repair are well-vascularized ducts, tension-free anastomosis, and complete drainage of hepatic segments, and all are achievable with robotic-assisted approach.

Methods: This was a retrospective study of our prospectively collected database of patients with iatrogenic bile duct injury who underwent robotic-assisted Roux-en-Y hepaticojejunostomy.

Minimally invasive approach (robotic and laparoscopic) to biliary-enteric fistula secondary to cholecystectomy bile duct injury.

Spontaneous biliary-enteric fistula after laparoscopic cholecystectomy bile duct injury is an extremely rare entity. Y-en-Roux hepaticojejunostomy has been demonstrated to be an effective surgical technique to repair iatrogenic bile duct injuries. Seven consecutive patients underwent robotic-assisted (n = 5) and laparoscopic (n = 2) biliary-enteric fistula resection and bile duct repair at our hospital from January 2012 to May 2017.

Intraoperative endoscopy prevents technical defect related leaks in laparoscopic Roux-en-Y gastric bypass: A randomized control trial.

Background: Postoperative anastomotic leaks, bleeding and stenosis are major causes of morbidity after laparoscopic Roux-en-Y gastric bypass (LRYGB). Retrospective studies suggest that intraoperative endoscopy reduces the incidence of these complications.

Methods: We conducted a prospective randomized controlled trial in a single institution between March 2013 and January 2016.

Adipocyte Size and Leptin Receptor Expression in Human Subcutaneous Adipose Tissue After Roux-en-Y Gastric Bypass.

The molecular mechanisms implicated in pronounced weight loss and metabolic benefits after bariatric surgery are still unknown. Adipocyte phenotype and metabolism have not been entirely explored. However, some features of adipocyte function have been studied, such as adipocyte size and inflammation, which are both reduced after bariatric surgery.

Laparoscopic Choledochoduodenostomy.

Introduction: Today's options for biliary bypass procedures, for difficult choledocholithiasis, range from open surgery to laparo-endoscopic hybrid procedures. The aim of this study was to analyze the outcomes of patients with difficult choledocholithiasis treated with laparoscopic choledochoduodenostomy.

Methods: We performed a prospective observational study from March 2011 to June 2016.

Laparoscopic Versus Open Surgery for Abdominal Trauma: A Case-Matched Study.

Background: The use of laparoscopic surgery in abdominal emergencies, such as in trauma, has had a slow acceptance. The advantages described with this approach include less postoperative pain, faster recovery, quicker return to everyday activities, and fewer wound complications. The aim of this retrospective study was to compare outcomes following laparoscopic versus open surgery for abdominal trauma (either blunt or penetrating).

[Skills comparison using a 2D vs. 3D laparoscopic simulator].

Background: The development and application of 3D images in laparoscopic surgery has brought the benefit of in-depth perception that traditional laparoscopic surgery lacked. Previous studies in surgical populations have demonstrated the advantages of 3D technology. To limit bias of the previous experiences of participants, this study was performed in a population without any experience in this area.

Laparoscopic hepaticojejunostomy after bile duct injury.

Background: The incidence of bile duct injuries (BDI) after cholecystectomy, which is a life-threatening condition that has several medical and legal implications, currently stands at about 0.6%. The aim of this study is to describe our experience as the first center to use a laparoscopic approach for BDI repair.

[Robotic surgery].

Medicine has experienced greater scientific and technological advances in the last 50 years than in the rest of human history. The article describes relevant events, revises concepts and advantages and clinical applications, summarizes published clinical results, and presents some personal reflections without giving dogmatic conclusions about robotic surgery. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) defines robotic surgery as a surgical procedure using technology to aid the interaction between surgeon and patient.

[Vaginal evisceration. Report of a case and a literature review].

Background: Vaginal evisceration is a rare event associated to be associated with several factors. In premenopausal women it is often associated with trauma during intercourse, rape, iatrogenic injury and introduction of foreign objects. In postmenopausal women 73% of cases are associated with previous vaginal surgery or hysterectomy.

Hepatic expression of ghrelin and adiponectin and their receptors in patients with nonalcoholic fatty liver disease.

Background & Aim: Adiponectin and ghrelin are hormones that participate in hepatic lipid metabolism, and their expression in liver tissue could have important implications for nonalcoholic fatty liver disease (NAFLD). The aim of this study was to evaluate the hepatic expression of ghrelin, adiponectin, AdipoR, and IL-6 in patients with NAFLD and normal liver.

Methods: We studied patients with clinical-pathological diagnosis of NAFLD or a normal liver.

[Endoscopy and bariatric surgery. A new challenge?].

Background: Obesity in Mexico appears with a frequency of 38.4% in men and 43.3% in women.

Objective: To describe the technique employed and our experience with primary laparoscopic repair of distal esophageal perforations produced during laparoscopic esophagomyotomy, as well as to evaluate the outcomes.

Materials And Methods: We analyzed six cases of patients with primary achalasia in whom distal esophageal mucosal perforations were caused during laparoscopic esophagomyotomy. A primary repair and fundoplication was performed in five cases; in the sixth patient, the perforation could not be recognized during the surgical procedure.

[Laparoscopic drainage of liver abscess. Initial experience].

Background: Radiologically guided percutaneous drainage has proven to be simple and effective and currently is considered the gold standard of care with success rates between 80 and 87%. However, not all abscesses are amenable to or will resolve with percutaneous drainage. The purpose of this study is to report our 1-year initial experience with laparoscopic drainage of liver abscesses.
