Two-Year Results of Sleeve Gastrectomy Combined with Posterior Fundoplication for Obesity Patients with Gastroesophageal Reflux Disease.

Introduction: Currently, gastroesophageal reflux disease (GERD) is the main side effect after sleeve gastrectomy (SG), causing discomfort and potential long-term risks. Surgical techniques combining fundoplication with SG are being evaluated to limit postoperative GERD.

Methods: This single-center retrospective study evaluated patients who underwent SG with posterior fundoplication in the context of GERD between 2018 and 2021, with postoperative follow-up up to 24 months.

Delayed post-pancreatectomy hemorrhage and bleeding recurrence after percutaneous endovascular treatment: risk factors from a bi-centric study of 307 consecutive patients.

Purpose: Delayed post-pancreatectomy hemorrhage (PPH) is still one of the most dreaded complications after pancreatic surgery. Its management is now focused on percutaneous endovascular treatments (PETs).

Methods: Between 2013 and 2019, 307 patients underwent pancreatic resection.

French survey on a cohort of emergency general surgery modifications induced by lockdown of the SARS-CoV-2 pandemic.

Purpose: The brutal COVID-19 pandemic has majorly impacted populations and health systems, and surgeons have observed dramatic changes in their daily clinical activities. A survey of French digestive surgeons was conducted to assess these changes.

Methods: An electronic survey was sent to French digestive and general surgeons in the Societe Francaise de Chirurgie Digestive (SFCD) to assess the surgeons' daily activity during the pandemic and investigate changes in patients' management.

Prospective study on predictability of complications by pancreatic surgeons.

Purpose: We evaluated the intuition of expert pancreatic surgeons, in predicting the associated risk of pancreatic resection and compared this "intuition" to actual operative follow-up. The objective was to avoid major complications following pancreatic resection, which remains a challenge.

Methods: From January 2015 to February 2018, all patients who were 18 years old or more undergoing a pancreatic resection (pancreaticoduodenectomy [PD], distal pancreatectomy [DP], or central pancreatectomy [CP]) for pancreatic lesions were included.

Is diverting loop ileostomy necessary for completion proctectomy with ileal pouch-anal anastomosis? A multicenter randomized trial of the GETAID Chirurgie group (IDEAL trial): rationale and design (NCT03872271).

Background: There is no quality evidence of the benefit of defunctioning ileostomy (DI) in ileal pouch-anal anastomoses (IPAAs) performed for inflammatory bowel disease (IBD), but most surgical teams currently resort to DI. In the case of a staged procedure with subtotal colectomy first, completion proctectomy with IPAA is performed for healthy patients, namely, after nutritional support, inflammation reduction and immunosuppressive agent weaning. Therefore, the aim of this trial is to assess the need for systematic DI after completion proctectomy and IPAA for IBD.

An Experimental Study of Intraluminal Hyperpressure Reproducing a Gastric Leak Following a Sleeve Gastrectomy.

Introduction: A gastric leak (GL) represents the main post-operative complication following a sleeve gastrectomy (SG) and occurs most commonly at the top of the stapling, without any clear explanation.

Objective: This experimental study evaluates the biomechanical behavior of post-SG gastric specimens using both insufflation and tensile tests.

Materials And Methods: A total gastrectomy followed by an ex vivo SG was performed in 15 pigs.

Preoperative Prediction of Small Bowel Length Using CT Scan and Tridimensional Reconstructions: a New Tool in Bariatric Surgery?

Purpose: During Roux-en-Y-gastric Bypass, the limb lengths are preoperatively determined regardless of individual small bowel length (SBL), which presents a great variability. Few studies highlighted anthropometric factors associated with SBL, and none attempted to predict SBL preoperatively.

Objective: The aim of this study is to evaluate factors correlated to SBL (anthropometric and radiologic) and to establish a preoperative SBL prediction.

Experimental Procedure of Compression Anastomosis Using Fragmented Rings: A Porcine Model.

Background: Compression anastomosis has been recently abandoned because of a nonsuperiority compared to stapling anastomosis. Nonremoval of the rings has frequently been reported and this technique does not support a routine use. The aim of this experimental study was to assess the feasibility of anastomosis using compression with a device consisting of fragmented rings.

Effectiveness of pure argon for renal transplant preservation in a preclinical pig model of heterotopic autotransplantation.

Background: In kidney transplantation, the conditions of organ preservation following removal influence function recovery. Current static preservation procedures are generally based on immersion in a cold-storage solution used under atmospheric air (approximately 78 kPa N2, 21 kPa O2, 1 kPa Ar). Research on static cold-preservation solutions has stalled, and modifying the gas composition of the storage medium for improving preservation was considered.

A multicentre, randomised, controlled trial to assess the safety, ease of use, and reliability of hyaluronic acid/carboxymethylcellulose powder adhesion barrier versus no barrier in colorectal laparoscopic surgery.

Background: Intra-peritoneal adhesions are frequent following abdominal surgery and are the most common cause of small bowel obstructions. A hyaluronic acid/carboxymethylcellulose (HA/CMC) film adhesion barrier has been shown to reduce adhesion formation in abdominal surgery. An HA/CMC powder formulation was developed for application during laparoscopic procedures.

Biliary complications after pancreaticoduodenectomy: skinny bile ducts are surgeons' enemies.

Background: The aim of this study was to determine the incidence and predisposing factors of biliary complications (BCs) after pancreaticoduodenectomy (PD) and report our experience in managing these BCs. Pancreatic surgery, particularly PD, has benefited from improvements in operative techniques and postoperative care and is currently safer in terms of mortality. However, the morbidity associated with PD remains high, including frequent complications such as delayed gastric emptying and pancreatic fistulas.

Endoscopic treatment of mandibular condylar fractures in live minipigs: benefits of the operative learning curve.

Endoscopic treatment of mandibular condyle fractures is a minimally invasive technique that avoids the complications of open reduction and internal fixation. We have used live minipigs as an animal model for learning and training the technique. Fourteen condylar fractures were created, reduced, and internally plated in 7 minipigs using an endoscopic approach by a surgeon with no previous experience of the technique.

Biomechanical characterisation of fresh and cadaverous human small intestine: applications for abdominal trauma.

Intestinal injuries are responsible for significant morbidity and mortality arising from trauma to the abdomen. The biomechanical characterisation of the small intestine allows for the understanding of the pathophysiological mechanisms responsible for these injuries. Studies reported in the literature focus principally on quasi-static tests, which do not take into account the stresses experienced during high kinetic trauma.

Three-dimensional determination of variability in colon anatomy: applications for numerical modeling of the intestine.

Background: Precise knowledge of variability in colonic anatomy is of great importance for numerical modeling studies of the abdomen. This knowledge would allow the creation of personalized models for the gastrointestinal tract used for surgical simulations or in studies of virtual trauma.

Materials And Methods: To determine the colonic configuration in the general population and define its variability by gender, age, and corpulence, the layout of the colon was determined via the following reference points: ileocecal junction, left and right colonic flexures, and colosigmoid junction (CSJ).

Postoperative efficacy and safety of vessel sealing: an experimental study on carotid arteries of the pig.

Background: The aim of this preclinical study was to analyze the burst pressure of large in vivo sealed vessels, not just immediately, but also in the first 7 postoperative days.

Methods: In 26 anesthetized pigs, the right carotid artery was sealed and cut using a novel device that integrates bipolar and ultrasonic energy. The animals were then awakened.

Impact of laparoscopy simulator training on the technical skills of future surgeons in the operating room: a prospective study.

Background: The efficacy of laparoscopy simulators remains controversial.

Methods: This was a comparative prospective study that evaluated the impact of simulator training on technical competence during a real surgical procedure. Residents were divided into 3 groups: the Mcgill Inanimate System for Training and Evaluation of Laparoscopic Skills (MISTELS) group, training on a simple simulator; LAP Mentor group, training on a virtual simulator; and control group.

The Rapunzel syndrome: a hard-to-swallow tale.

Introduction: Rapunzel syndrome is a rare entity comprising of a large gastroduodenal trichobezoar due to trichotillomania. Its treatment is often surgical.

Case Report: A 27-year-old patient was investigated after an upper gastro-intestinal tract obstruction.

An endoscopic strategy for management of anastomotic complications from bariatric surgery: a prospective study.

Background: Treatment of anastomotic fistulas after bariatric surgery is difficult, and they are often associated with additional surgery, sepsis, and prolonged non-oral feeding.

Objective: To assess a new, totally endoscopic strategy to manage anastomotic fistulas.

Design: Prospective study.

Very low stapling of the anal canal in laparoscopic ileal pouch-anal anastomosis.

Performing a double-stapled ileal pouch-anal anastomosis requires very low stapling of the anal canal. However, this laparoscopic procedure is often difficult to perform. We describe here a transanal method of everting the rectum, which allows easier transection under visual control and a sufficiently low anastomosis.

Preoperative infliximab treatment and postoperative complications after laparoscopic restorative proctocolectomy with ileal pouch-anal anastomosis: a case-matched study.

Background: Infliximab offers promising new therapeutic options for treatment of moderate to severe ulcerative colitis. However, several studies suggest that it increases postoperative complication rates for patients who later require a restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). This study aimed to assess the postoperative course of patients after laparoscopic IPAA, comparing those who had and those who had not received infliximab before surgery.

Mid-term functional outcome of laparoscopic restorative proctocolectomy: a prospective study of 40 consecutive cases.

Introduction: This prospective study aimed to analyze the functional outcome after a two-stage laparoscopic total proctocolectomy with ileal pouch-anal anastomosis.

Materials And Methods: From May 1999 to May 2008, 68 consecutive two-stage laparoscopic total proctocolectomies with ileal pouch-anal anastomosis were performed (ulcerative colitis: n = 61; familial adenomatous polyposis: n = 7). A covering ileostomy was used in all patients.

Results of non-operative therapy for delayed hemorrhage after pancreaticoduodenectomy.

Introduction: Hemorrhage after pancreaticoduodenectomy is a life-threatening complication, which occurs in 4% to 16% of cases, even in experienced centers. Many diagnostic and therapeutic options exist but no one has yet established management guidelines. This study aimed to determine the role of conservative management in delayed hemorrhage.

Open versus laparoscopic (assisted) ileo pouch anal anastomosis for ulcerative colitis and familial adenomatous polyposis.

Background: Restorative proctocolectomy with ileo pouch anal anastomosis (IPAA) is the main surgical treatment for patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP). With the advancements of minimal-invasive surgery this demanding operation is increasingly being performed laparoscopically. Therefore, the presumed benefits of the laparoscopic approach need to be systematically evaluated.

Laparoscopy-assisted left ovarian vein transposition to treat one case of posterior nutcracker syndrome.

We report one case of posterior nutcracker syndrome treated by left ovarian vein (LOV) transposition. A 36-year-old woman was suffering from nutcracker syndrome associated with pelvic congestion syndrome. Color duplex scan, computed tomographic scan, and angiography demonstrated a stenosis of a retroaortic left renal vein with proximal dilatation and incompetence of the LOV.

3D reconstruction of the diaphragm for virtual traumatology.

This study lies within the scope of passive road safety, and more particularly injury mechanisms of the abdominal area. The finite element modeling, which makes it possible to simulate a road accident and to observe the possible bone fractures or internal tissue injuries, allows large projections in the comprehension of injury mechanisms. However, the digital models already available and used in accidentology do not offer as one very simplified description of the diaphragm, as well for its geometry as for its bracing aspect and the modifications that this could induce in the behavior of abdominal organs and vessels at impact.
