Augmented reality (AR) has been successfully providing surgeons an extensive visual information of surgical anatomy to assist them throughout the procedure. AR allows surgeons to view surgical field through the superimposed 3D virtual model of anatomical details. However, open surgery presents new challenges. This study provides a comprehensive overview of the available literature regarding the use of AR in open surgery, both in clinical and simulated settings. In this way, we aim to analyze the current trends and solutions to help developers and end/users discuss and understand benefits and shortcomings of these systems in open surgery...

Mucocele of the gallbladder is an overdistended gallbladder filled with mucoid content. It is under-reported in humans, and literature review showed insufficient data about the incidence and the factors affecting the laparoscopic management. We aim to evaluate the intraoperative aspiration of the mucoid contents of the gallbladder as a factor influencing the outcome of the treatment. A prospective cohort database analysis of the results of patients who were diagnosed as mucocele of the gallbladder and treated laparoscopically between January 2003 and December 2012 was done...

BACKGROUND: The surgical management of rectovaginal fistulae associated with Crohn's disease is often frustrated by poor results regardless of the different techniques. The outcomes of the gracilis muscle transposition (GMT) for the treatment of recurrent Crohn's-associated fistulae are still debated. The aim of the study is to determine whether the success rate of GMT is similar in Crohn's disease patients and in a control group. MATERIALS AND METHODS: All patients undergoing GMT for rectovaginal or pouch-vaginal fistula were collected from a prospectively maintained database (2005-2016)...

Robotic liver surgery has been considered as a unique opportunity to overcome the traditional limitations of laparoscopy; thus, it can potentially extend the indications of minimally invasive liver surgery. From April 2015 to May 2017, 35 patients underwent fully robotic left hepatectomy. The mean operative time was 315 min (200-445 min) and the mean estimated blood loss was 245 ml (125-628 ml). Pringle maneuver was required in six cases. Cancer was the indication for surgery in all patients (14 liver metastases, 18 hepatocellular carcinomas and 3 cholangiocarcinomas)...

The purpose of our analysis was to assess the effects of pulmonary hypertension (PH) on clinical outcomes of patients undergoing laparoscopic procedures. Pulmonary hypertension alters physiologic patterns that has the potential to complicate laparoscopic procedures, however, an in-depth analysis evaluating survival outcomes, complications, and associated comorbidities has not been done before. Data from the National Inpatient Survey were used to identify 179,663 patients without PH and 1453 patients with PH undergoing laparoscopic procedures from the years 2003-2013...

The aim was to report our experience with delayed colo-anal anastomosis (DCA) to avoid permanent stoma for complex rectal cases evaluating short- and long-term outcomes. Nine patients who underwent DCA from 2011 to 2016 were collected and analysed case by case. We considered medical history and surgical outcomes. Long-term bowel function was evaluated using the Wexner and low anterior resection syndrome (LARS) score at 6, 12 and 24 months. The range from previous surgery and salvage procedure was 337 days...

According to the data of the GLOBOCAN-network of the World Health Organization, there were 952,000 (6.8% of the total) new cases of gastric cancer in 2012, making it the fifth most common malignancy in the world. It represents a substantive change since the very first estimates in 1975 when stomach cancer was the most common neoplasm. More than 70% of cases (677,000 cases) occur in developing countries, and half the world total occurs in Eastern Asia, mainly in China. Gastric cancer is the third leading cause of cancer death in both sexes worldwide (Globocan, Estimated cancer incidence, mortality and prevalence worldwide in 2012, http://globocan...

The role of loco-regional treatment of peritoneal carcinomatosis using intraperitoneal chemotherapy is still investigated. Actually, new technologies are suitable for these procedures, especially a new hybrid system using CO2 called Peritoneal Recirculation System (PRS-1.0 Combat). A HIPEC procedure in a porcine model using the PRS system was conducted. The objective of experimentation was to assess the distribution of liquid inside the abdomen, by using methylene blue instead of chemotherapy. Moreover, we positioned six different thermal probes in different abdominal regions inside the abdomen to measure the temperature during procedure...

The optimal management of patients with resection line involvement after endoscopic or surgical treatment for gastric cancer is debated. In contrast to previous reports, we examined both the experience of endoscopists and surgeons in early-stage lesions and the wide variation in treatments proposed for advanced disease in case of infiltration of resection margins. A PubMed search for papers using the key words: gastric or stomach cancer, or Carcinoma; gastrectomy and positive margins; surgical margins or resection line or endoscopic margin involvement; and R1 resection, from January 2000 to July 2015 was undertaken...

The objective of this study is to describe the compliance to D2 lymphadenectomy in laparoscopic gastrectomy. Radical partial or total gastrectomy with modified D2 lymphadenectomy is the standard of care for locally advanced gastric cancer. It is unclear whether compliance to D2 lymphadenectomy in laparoscopy is comparable to that in open surgery. A review of the literature was performed and results are described in a descriptive review. Available randomized trials are mostly performed for early gastric cancer, for which formal D2 lymphadenectomy is usually not required...

The diagnostic-therapeutic pathways (DTPs) are emerging as useful instruments for clinical management of complex diseases as gastric cancer, whose treatment is challenging and requires a multidisciplinary approach. However, the DPTs of patients with gastric cancer are still not defined yet. The aim of this study was to define the optimal DPT to be applied for patients with gastric cancer in the Veneto region. Rather than defining the ideal DTPs a priori, we conducted a preliminary research by analyzing the differences in the actual DPTs for patients with gastric cancer among different hospitals (hub and spokes) in Veneto...

Minimal-invasive gastrectomy has been established as commonly used method for the early gastric cancer in Korea and Japan. From the first laparoscopic cancer gastrectomy in 1992 in Japan, numerous prospective randomized trials from these two countries have gained the evidence for non-inferiority or even specific benefits compared to open surgery. In Korea, the "Korean Laparoscopic Gastrointestinal Surgical Study Group" (KLASS group) founded, in 2004, successfully gained evidence not only in regards of oncological safety of laparoscopic gastrectomy, but also for the impact of different reconstruction methods and alternative extents of luminal resection on postoperative outcome and quality of life...

Gastric cancer with Laurèn diffuse types is increasing in the West. The raising trend is more evident when considering signet ring cells (SRC) histology. However, to control the biologic potential of this GC subtype, some hypotheses of tailored therapeutic strategies for SRC cancers have been made. A review of the literature was performed using the key words "signet ring cells" AND "gastric cancer". Results of literature review were descriptively reported. Endoscopic submucosal dissection (ESD), according to the Japanese extended criteria, could be a therapeutic option for early SRC tumours...

Treatment options to gastric cancer (GC) have been changing in recent years from a standard to a tailored approach. Different individualized procedures can range from endoscopic resection, D2 with open or minimally invasive approach, to neo-adjuvant therapy followed by extended surgery. In more advanced stages, a combined approach with the inclusion of intraperitoneal chemo-hyperthermia (HIPEC) may represent a new advanced option. The inclusion of histological type according to Laurén classification in the flowchart of treatment could increase both accuracy and effectiveness of such tailored approach...
