Liver ischemia-reperfusion injury: From trigger loading to shot firing.

An ischemia-reperfusion injury (IRI) results from a prolonged ischemic insult followed by the restoration of blood perfusion, being a common cause of morbidity and mortality, especially in liver transplantation. At the maximum of the potential damage, IRI is characterized by 2 main phases. The first is the ischemic phase, where the hypoxia and vascular stasis induces cell damage and the accumulation of damage-associated molecular patterns and cytokines.

Laparoscopic versus Open Surgery for Gastric Cancer in Western Countries: A Systematic Review and Meta-Analysis of Short- and Long-Term Outcomes.

Background. The advantages of a laparoscopic approach for the treatment of gastric cancer have already been demonstrated in Eastern Countries. This review and meta-analysis aims to merge all the western studies comparing laparoscopic (LG) versus open gastrectomies (OG) to provide pooled results and higher levels of evidence.

From "Cure" to "Care": The Role of the MultiDisciplinary Team on Colorectal Cancer Patients' Satisfaction and Oncological Outcomes.

Background: MultiDisciplinary Team (MDT) are held to undertake decisions regarding the whole aspect of oncological diseases. Over the years, they acquired a collaborative approach where clinical decisions are shared by all members. Different guidelines recommend the implementation of MDT, in order to improve the outcomes of these patients.

Democratizing Flexible Endoscopy Training: Noninferiority Randomized Trial Comparing a Box-Trainer vs a Virtual Reality Simulator to Prepare for the Fundamental of Endoscopic Surgery Exam.

Background: A considerable number of surgical residents fail the mandated endoscopy exam despite having completed the required clinical cases. Low-cost endoscopy box trainers (BTs) could democratize training; however, their effectiveness has never been compared with higher-cost virtual reality simulators (VRSs).

Study Design: In this randomized noninferiority trial, endoscopy novices trained either on the VRS used in the Fundamental of Endoscopic Surgery manual skills (FESms) exam or a validated BT-the Basic Endoscopic Skills Training (BEST) box.

Multicentric validation of EndoDigest: a computer vision platform for video documentation of the critical view of safety in laparoscopic cholecystectomy.

Background: A computer vision (CV) platform named EndoDigest was recently developed to facilitate the use of surgical videos. Specifically, EndoDigest automatically provides short video clips to effectively document the critical view of safety (CVS) in laparoscopic cholecystectomy (LC). The aim of the present study is to validate EndoDigest on a multicentric dataset of LC videos.

Statistical models to preoperatively predict operative difficulty in laparoscopic cholecystectomy: A systematic review.

Background: Laparoscopic cholecystectomy operative difficulty is highly variable and influences outcomes. This systematic review analyzes the performance and clinical value of statistical models to preoperatively predict laparoscopic cholecystectomy operative difficulty.

Methods: PRISMA guidelines were followed.

2D 3D laparoscopic right colectomy: A propensity score-matching comparison of personal experience with systematic review and meta-analysis.

Background: The benefits of laparoscopic approach for right colectomy have been well established. However, the technical difficulty to construct the intra-corporeal anastomosis is still cumbersome.

Aim: To analyze the results of 3D and 2D laparoscopic right colectomy and to compare it to the published series through a systematic review and meta-analysis.

Robotic versus open oncological gastric surgery in the elderly: a propensity score-matched analysis.

Although there is no agreement on a definition of elderly, commonly an age cutoff of ≥ 65 or 75 years is used. Even if robot-assisted surgery is a validated option for the elderly population, there are no specific indications for its application in the surgical treatment of gastric cancer. The aim of this study is to evaluate the safety and feasibility of robot-assisted gastrectomy and to compare the short and long-term outcomes of robot-assisted (RG) versus open gastrectomy (OG).

Laparoscopic versus open distal gastrectomy for locally advanced gastric cancer in middle-low-volume centers in Western countries: a propensity score matching analysis.

Background: Gastrectomy with D2 lymphadenectomy is the standard treatment for patients with resectable gastric cancer. Laparoscopic distal gastrectomy (LDG) is routinely performed for early gastric cancer, and its indications are increasing even for locally advanced gastric cancer. The aim of this study is to compare two middle-low-volume centers in Western countries experience on LDG versus open distal gastrectomy (ODG) for locally advanced gastric cancer in terms of surgical and oncological outcomes.

Training in bariatric and metabolic endoscopy.

The limited penetration of bariatric surgery and the scarce outcome of pharmacological therapies created a favorable space for primary bariatric endoscopic techniques. Furthermore, bariatric endoscopy is largely used to diagnose and treat surgical complications and weight regain after bariatric surgery. The increasingly essential role of endoscopy in the management of obese patients results in the need for trained professionals.

Endoscopic Preoperative Tattooing and Marking in the Gastrointestinal Tract: A Systematic Review of Alternative Methods.

An accurate and reliable localization of endoluminal gastrointestinal (GI) lesions is crucial, particularly during minimally invasive surgery. As an extreme consequence, a misdetected GI lesion can lead to the resection of the wrong segment, especially in colorectal surgery. A preoperative endoscopic marking is recommended in case of GI lesions, which are expected to be difficult to detect from the serosal side.

Development of an enhanced recovery after surgery (ERAS) protocol in laparoscopic colorectal surgery: results of the first 120 consecutive cases from a university hospital.

The ERAS represents a dynamic culmination of upon perioperative care elements, successfully applied to different surgical specialties with shorter hospital stay and lower morbidity rates. The aim of this study is to describe the introduction of the ERAS protocol in colorectal surgery in our hospital analysing our first series. Between September 2014 and June 2016, 120 patients suffering from colorectal diseases were included in the study.

Influence of perineural invasion in predicting overall survival and disease-free survival in patients With locally advanced gastric cancer.

Background: The aim of the present study was to evaluate the prognostic significance of perineural invasion (PNI) in locally advanced gastric cancer patients who underwent D2 gastrectomy and adjuvant chemotherapy.

Methods: The records of a series of 103 patients undergoing D2 gastrectomy with curative intent combined with adjuvant chemotherapy from January 2004 to December 2014 were retrospectively reviewed.

Results: PNI was positive in 47 (45.

Does ghost ileostomy have a role in the laparoscopic rectal surgery era? A randomized controlled trial.

Background: Anastomotic leakage following anterior rectal resection is the most important and most commonly faced complication of laparoscopy and open surgery. To prevent this complication, the construction of a preventing stoma is usually adopted. It is not easy to decide whether to construct a protective stoma in patients with a medium risk of anastomotic leakage.

Modified technique for performing STARR with Contour Transtar™.

Stapled Transanal Rectal Resection (STARR) performed using CCS-30 Contour Transtar™ despite its recent introduction seems to be an effective surgical procedure to treat obstructed defecation syndrome. The major constraint of this procedure is the need to open the prolapse longitudinally using the CCS-30. This is often difficult and can lead to an inadequate or spiralling resection.

Can a curved stapler made for open surgery be useful in laparoscopic lower rectal resections? Technique and experience of a single centre.

Background: The use of laparoscopy to perform lower anterior rectal resection is increasing worldwide because it allows better visualisation and rectal mobilisation and also reduces postoperative pain and recovery. The Contour Curved Stapler (CCS) is a very helpful device because of its curved profile that enables better access into the pelvic cavity and allows rectal closure and section to be performed in one shot. In this paper, we present an original technique to use this device, made for open surgery, in laparoscopy and the results of our experience.
