Lemmel's Syndrome: A Report of Two Cases at the Hospital General Dr. Manuel Gea Gonzalez in Mexico City.

The term ¨Lemmel Syndrome¨ is used to describe obstructive jaundice that is secondary to periampullary duodenal diverticula (PDD) in the absence of choledocholithiasis or neoplasia. PDD is found in 22% of the population. According to our knowledge, only two cases of Lemmel syndrome have been reported in Mexico.

Three-dimensional vs two-dimensional laparoscopic gastric bypass for manual gastrojejunal anastomosis: A prospective and randomized trial.

Objective: The objective of this study was to compare the total procedure time and task-specific execution time in gastric bypass using a three-dimensional (3D) versus two-dimensional (2D) imaging system.

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.

Laparoscopic cholecystectomy after endoscopic treatment of choledocholithiasis: a retrospective comparative study.

Patients with combined choledocholithiasis and cholecystitis require treatment of both diseases. The aim of our study was to analyze perioperative results of next-day (< 24 h) vs. early (> 24 h) laparoscopic cholecystectomy (LC) after endoscopic clearance of common bile duct stones.

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.

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.

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.

C-Reactive Protein as a Predictor of Difficult Laparoscopic Cholecystectomy in Patients with Acute Calculous Cholecystitis: A Multivariate Analysis.

Background: Laparoscopic cholecystectomy (LC) is the treatment of choice for mild and moderate acute cholecystitis. The aim of this study was to analyze the utility of C-reactive protein (CRP) as a predictor of difficult laparoscopic cholecystectomy (DLC) in patients with acute cholecystitis.

Materials And Methods: We conducted a prospective study.

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.

[Transgastric laparo-endoscopic approach for difficult access lesions. Experimental mode].

Background: Gastric neoplasms can be treated by laparoscopy in a safe and efficient way. Some lesions are not accessible to laparoscopic surgery due to their location. A transgastric approach is proposed as an alternative.

[Laparoscopic choledochoduodenostomy as an optional treatment choledocholithiasis].

Introduction: Choledochoduodenostomy is indicated for unsolved choledocholithiasis and biliary malignant or benign stenosis. This surgical procedure has been feared for its potential complications. This article shows our initial experience with this laparo-endoscopic approach.
