Though laparoscopic cholecystectomy (LC) was highly criticized in its early stages, it quickly grew to become a new standard of care and has revolutionized the field of general surgery. Now emerging robotic technology is making its way into the minimally invasive arena. Robotic cholecystectomy (RC) is often disparaged as a costly technology that can lead to increased operative times with outcomes that are quite similar to LC. However, this perspective is skewed as many existing studies were performed in the early phase of learning for this procedure...

INTRODUCTION: Gallbladder cancer (GBC) is a rare tumor in developed countries. Chile has one of the highest incidences worldwide. For patients affected by resectable T1b or more advanced GBC, radical cholecystectomy (RC) is considered the standard therapy. Our aim is to describe the surgical technique and clinical-pathological results of patients undergoing totally laparoscopic radical resection of GBC. METHODS: Patients undergo laparoscopic radical resection for primary and incidental GBC, between the years 2009 and 2016 in two centers from Chile...

Liver resection is the standard treatment for any liver lesion. Laparoscopic liver resection is associated with lower intra-operative blood loss and fewer complications than open resection. Access to the posterior part of the right liver lobe is very uncomfortable and difficult for surgeons due the anatomic position, especially when employing laparoscopic surgery. Based on these experiences, a new laparoscopic device was developed that is capable of bending its long axis and allowing the application of radiofrequency energy in areas that were not technically accessible...

Multiple studies have demonstrated the benefits of laparoscopic colorectal surgery (LCS), but in several countries it has still not been widely adopted. LCS training is associated with several challenges, such as patient safety concerns and a steep learning curve. Current evidence may facilitate designing of efficient training curricula to overcome these challenges. Basic training with virtual reality simulators has witnessed meteoric advances and may be essential during the early parts of the learning curve...

Muscle relaxation is a routine part of anesthesia and has important advantages. However, the lingering effects of muscle relaxants in the postoperative period have historically been associated with postoperative adverse events. Neuromuscular reversal, together with neuromuscular monitoring, is a recognized strategy to reduce the rate of postoperative residual relaxation but has only marginally improved outcome in the past few decades. Sugammadex, a novel reversal agent with unique encapsulating properties, has changed the landscape of neuromuscular reversal and opened up new opportunities to improve patient care...

Laparoscopic technology is gradually accepted in gastric cancer surgery, whose efficacy has been demonstrated by some clinical researches. Randomized controlled trials (RCT) are considered as the most important evidence to prove clinical outcomes of laparoscopic surgery for gastric cancer. Korean gastric surgeons have made great contributions to RCT in laparoscopic gastric cancer surgery. KLASS (Korean Laparoscopic Gastrointestinal Surgery Study Group) is one of the most important forerunner and global leader of clinical trials of gastric cancer treatment...

According to Japanese gastric cancer treatment guidelines, the standard operation for locally advanced upper third gastric cancer is the total gastrectomy with D2 lymphadenectomy, which includes the dissection of the splenic hilar lymph nodes. With the development of minimally invasive ideas and surgical techniques, laparoscopic spleen-preserving splenic hilar lymph node dissection is gradually accepted. It needs high technical requirements and should be carried out by surgeons with rich experience of open operation and skilled laparoscopic techniques...

Neoadjuvant chemotherapy combined with radical gastrectomy is one of the most important parts of the multimodality therapy strategies for locally advanced gastric cancer. With the development of laparoscopic technique in recent decades, laparoscopic technique plays a more and more important role in the surgical treatment of gastric cancer. Neoadjuvant chemotherapy, as a part of comprehensive treatment of gastric cancer, has gained more and more clinical supports and been recommended for guidelines. With the development of laparoscopic technique and clinical evidence, laparoscopic operation for advanced gastric cancer has been applied more and more widely...

Laparoscopic surgery has its unique minimally invasive advantages, however, taking the complex and difficult D2 lymph node dissection for advanced gastric cancer into consideration, laparoscopic gastrectomy was only applied in the treatment of early gastric cancer at its preliminary stage. With the development of more than a decade, many multicenter clinical data have confirmed the safety, feasibility and effectiveness of laparoscopic radical gastrectomy for early gastric cancer. Based on high-quality evidence-based medicine evidence, laparoscopic gastrectomy has been recommended as an optional treatment for stage I( gastric cancer by the Japanese Gastric Cancer Treatment Guidelines 2014(ver...

Many retrospective and cohort studies have shown that laparoscopic total gastrectomy(LTG) has advantages of less trauma, quicker recovery and better incision than open total gastrectomy, and is not inferior to laparotomy in safety and the short- and long-term outcomes, so it has been widely applied. However there is still a lack of high level evidence-based basis. At present, several prospective multicenter clinical studies are being carried out in China, Japan and South Korea which have high incidence of gastric cancer to demonstrate the safety and feasibility of LTG and evaluate its long-term outcomes as well...

INTRODUCTION: Recent advances in single-incision laparoscopic surgery (SILS) have caused increased difficulties when tying knots because of the limited working space. Although extracorporeal knot-tying techniques may be a practical alternative choice in SILS, it is not always appropriate. For example, sliding resistance may be encountered when tying knots for a Z-shaped suture, and it could damage the sutured tissue. MATERIALS AND SURGICAL TECHNIQUE: The clinch knot is a kind of slipknot that has been historically used by fishermen...

We present here a case of transduodenal ampullectomy for an ampullary neoplasm coexisting with gastric and colon cancer. The patient was a 72-year-old man who was referred to our hospital with a positive fecal blood test. Colonoscopy revealed advanced cancer in the descending colon. As part of the preoperative examination, for the colonic cancer, upper gastrointestinal endoscopy was performed. Endoscopy showed a 2 cm elevated lesion(0'-II a type)with subserosalinfil tration on the small curvature side of the upper part of the stomach, and a 2 cm elevated lesion on the papilla of Vater...

Laparoscopic and endoscopic colorectal intervention and operations have their basis in real-time, image-based decision-making and step-by-step sequenced technical progress. The capacity to visualise accurately malignant disease wherever it may be including within the primary lesion and its draining lymph node basin as well as at potential sites of metastatic harbour (i.e. peritoneum, liver and lung) would allow more accurate surgery at the time of operation and enable personalised, stratified surgical intervention...
