[Complicated right Bochdalek hernia].

The clinical case of a 53-year-old woman diagnosed with a right Bochdalek hernia complicated by intestinal obstruction is presented. This type of diaphragmatic hernia is rare, especially those located on the right side, but is the most common non-hiatal hernia. Her diagnosis focused on the computed tomography of the chest and abdomen and the repair was performed using a laparoscopic approach.

Double Internal Hernia: Laparoscopic Resolution.

Gastric bypass surgery is a common and effective procedure for obesity and associated comorbidities. However, long-term complications, such as internal hernias, can pose diagnostic and therapeutic challenges. Internal hernias after gastric bypass are rare but can lead to severe complications, including volvulus and bowel ischemia.

Sleeve gastrectomy as a bridge to maternity in a patient with obesity, infertility and tetraplegia. A case report.

Traumatic spinal cord injury (SCI) is a major cause of severe and permanent disability in young adults. Overweight and obesity are commonly observed among patients affected with SCI, with reports of a prevalence of over 60 and 30% respectively. Case report: A 34 year-old woman suffering from tetraplegia after sustaining a traumatic injury to C5-C6 at age 23 as a result of a motor vehicle accident was presented to our hospital's multidisciplinary bariatric team due to class II obesity.

Teaching strategies and outcomes in 3 different times of the COVID-19 pandemic through a dynamic assessment of medical skills and wellness of surgical trainees.

Background: The coronavirus disease 2019 pandemic had a substantial impact on surgical training programs. This study describes the teaching strategies and outcomes in 3 different times of the coronavirus disease 2019 pandemic through a dynamic assessment of medical skills and well-being of trainees.

Methods: Three surveys were administered during 2020 to general surgery residents and fellows in a university hospital in Argentina.

Laparoscopic Conversion of Gastric Plication to Roux-en-Y Gastric Bypass.

Purpose: Laparoscopic gastric plication (LGP) is a relative new bariatric procedure with a high revision rate, mostly to sleeve gastrectomy. There are few reported cases of conversion to Roux-en-Y gastric bypass (RYGB). The purpose of this video was to show the feasibility and safety, as well as the main technical aspects, of a laparoscopic conversion of gastric plication to RYGB.

Laparoscopic transcystic common bile duct exploration as treatment for choledocholithiasis after Roux-en-Y gastric bypass.

Background: Treatment of choledocholithiasis after Roux-en-Y gastric bypass (RYGB) is a therapeutic challenge given the altered anatomy. To overcome this technical difficulty, different modified endoscopic approaches have been described but significant morbidity accompanies these procedures. The aim of the present study is to report our experience with laparoscopic transcystic common bile duct exploration (LTCBDE) as treatment of choledocholithiasis after RYGB.

Effect of Roux-en-Y Gastric Bypass on Lipoprotein Metabolism and Markers of HDL Functionality in Morbid Obese Patients.

Purpose: Morbid obesity represents the most severe form of obesity and surgical intervention would be its only successful treatment. Bariatric surgery could generate modifications in carbohydrate metabolism and in lipid profile plus lipoprotein-associated proteins and enzymes, such as lipoprotein-associated phoslipase A (Lp-PLA), cholesteryl ester transfer protein (CETP), and paraoxonase (PON) 1. The aim of the present study was to analyze changes in inflammation markers, carbohydrate metabolism, and lipid parameters in patients who underwent bariatric surgery.

CoViD-19 Pandemic and Bariatric Surgery in Argentina.

Argentina was able to anticipate public health interventions in order to flatten the contagion curve of CoViD-19. Eighty-three surgeons answered an online survey to assess the impact of the pandemic on bariatric surgery (BS) in Argentina. Most of them showed a high economic dependence on BS.

Laparoscopic Removal of Eroded Non-Adjustable Gastric Band and Conversion to Roux-en-Y Gastric Bypass.

This video shows the case of a 64-year-old morbidly obese woman, with a non-adjustable gastric band, who consulted for weight regain and gastroesophageal reflux disease (GERD) symptoms and was converted to Roux-en-Y gastric bypass (RYGB). The operative technique included extensive lysis of adhesions, complete band dissection, partial gastrectomy of the fundus and body due to band erosion and conversion to RYGB.

Venous Malformation of the Esophagus.

Venous malformations are an extremely infrequent condition in the gastrointestinal tract, particularly in the esophagus. We report a rare case of an adult with an asymptomatic mass located in the mediastinum and in whom the diagnosis and treatment of a venous malformation of the esophagus was performed through a thoracoscopic approach. When dealing with a hypervascularized submucosal esophageal tumor, venous malformations can be among the differential diagnoses.

Intussusception as a complication of bariatric surgery in pregnant patients: report of one case and revision of the literature.

Occlusive complications after a laparoscopic Roux-in Y gastric bypass (LRYGB), appear mainly as fibrous membranes of wounds, internal hernias or intussusception. Intussusception after a bariatric surgery occurs in 0.1-0.

Esophageal adenocarcinoma five years after laparoscopic sleeve gastrectomy. A case report.

Introduction: Laparoscopic sleeve gastrectomy has become the most popular bariatric procedure worldwide. However, postoperative gastroesophageal reflux disease appearance is a matter of concern. Only two cases of esophageal adenocarcinoma after gastric sleeve have been described, none of them with preoperative endoscopic evaluation.

Transplantation with hyper-reduced liver grafts in children under 10 kg of weight.

Background: We had previously described a left lateral segment hyper-reduction technique capable of sizing the graft according to the volume of the abdominal cavity of the recipient.

Aim: The purpose of our study was to evaluate our 14-year live-donor liver transplantation experience with in situ graft hyper-reduction in children under 10 kg of weight.

Patients And Methods: Between January 1997 and May 2011, we performed 881 liver transplants.

Hepatic artery reconstruction first for the treatment of hilar cholangiocarcinoma bismuth type IIIB with contralateral arterial invasion: a novel technical strategy.

Background: En-bloc liver resection with the extrahepatic bile duct is mandatory to obtain tumour-free surgical margins and better long-term outcomes in hilar cholangiocarcinoma (CC). One of the most important criteria for irresectability is local extensive invasion to major vessels. As hilar CC Bismuth type IIIB often requires a major left hepatic resection, the invasion of the right hepatic artery (RHA) usually contraindicates this procedure.

Ileocolic intussusception due to intestinal metastatic melanoma. Case report and review of the literature.

The small intestine is a frequent site of melanoma metastases and the most common cause of secondary intestinal tumors. Even though, its presentation with intestinal obstruction due to intussusception is very rare. We present a 47-year-old woman with a medical history of facial melanoma operated 17 years ago and recently diagnosed of cervical recurrence who complained of abdominal pain of one week duration accompanied with vomiting and abdominal distension.
