The advent of laparoscopy has significantly improved postoperative outcomes in patients undergoing surgical repair of a paraesophageal hernia. Although this minimally invasive approach considerably reduces postoperative pain and recovery times, and may improve physiologic outcomes, laparoscopic paraesophageal hernia repair remains a complex operation requiring advanced laparoscopic skills and experience with the anatomy of the gastroesophageal junction and diaphragmatic hiatus. In this article, we describe our approach to patient selection, preoperative evaluation, operative technique, and postoperative management. Specific attention is paid to performing an adequate hiatal dissection and esophageal mobilization, the decision of whether to use a mesh to reinforce the crural repair, and construction of an adequate antireflux barrier (ie, fundoplication).

Laparoscopic intracorporeal colorectal anastomosis with double stapling technique is difficult because of unsuitable cutting angle in narrow pelvic cavity. For reasons of tilted and long linear staple line of rectal stump, circular anastomotic plane can make multiple intersections. The present study was designed to assess whether multiple intersections after double stapling technique is the risk factor of anastomotic complication in laparoscopic colorectal surgery.

Few studies of robotic gastric gastrointestinal stromal tumors (GISTs) resection have been conducted. This study was aimed to evaluate the robotic gastrotomy with intracorporeal suture for patients with GISTs located at cardia and subcardiac region.

Robotic gastrectomy (RG) has progressed rapidly in the last decade, overcoming many obstacles in laparoscopic technology. We compared surgical performance and short-term clinical outcomes between RG and laparoscopic gastrectomy (LG). In total, 163 patients with gastric cancer were randomly treated with RG (n=102) or LG (n=61). D2 lymphadenectomy was achieved in all patients. Digestive tract reconstruction in the RG group was performed by intracorporeal hand sewing, but extracorporeal anastomosis in the LG group was performed with a 25-mm circular stapler or linear stapler. Compared with the LG group, the RG group had less intraoperative blood loss (P=0.005) and more lymph nodes retrieved (P=0.000). Postoperative complications between the 2 groups were not significantly different during the 11-month follow-up (P=0.063). Compared with LG, RG is a feasible and safe approach with minimally invasive, satisfactory intracorporeal digestive tract reconstruction, and fast recovery. Multicenter randomized controlled studies of larger numbers of patients are needed.

This study introduces a novel technique for liver retraction during laparoscopic gastrectomy and assesses its impact on postoperative recovery. This study included 139 patients in whom Nelaton catheters (n=57) or Nathanson retractors (n=82) were used for liver retraction. Serum liver enzyme levels were measured preoperatively and on the first, second, third, fifth, and seventh postoperative days. Clinicopathologic features and postoperative recovery variables between the 2 groups were compared. The aspartate aminotransferase, alanine aminotransferase, and C-reactive protein levels were significantly lower (P<0.001, P<0.001, and P=0.007, respectively), and the day of first flatus, the day of initiating a soft diet, and the length of hospital stay were shorter in the Nelaton catheter U-shaped retractor group than those seen in the Nathanson retractor group (P=0.035, P=0.002, and P=0.024, respectively). Atraumatic liver retraction with Nelaton catheters is recommended in laparoscopic gastrectomy.

Portal-mesenteric tumor thrombosis represents a rare finding in patients with colorectal cancers. To our knowledge this is the first report of a patient diagnosed as having a wide stenosing right colon cancer with portal-superior mesenteric vein tumor thrombosis at the time of diagnosis, who was treated before surgery by positioning a percutaneous transhepatic Y-shaped stent through the main portal vein and the superior mesenteric vein. Percutaneous interventional procedures have gained worldwide acceptance for improving the symptoms of portal hypertension, because of their minimal invasiveness and high success rates with low number of complications. A multidisciplinary approach is mandatory in order to choose the best therapeutic option for the patients and the importance of a strong collaboration between interventional radiologist and surgeon has to be considered.

The evolution of guided imaging surgery is well known in recent years. As the field of action becomes more specific, learning and teaching are also more specific. State-of-the-art medical training should be mandatory in the field of general medicine and surgery in particular. In this work, we report on how to create a model for the formation of guided surgery by images in a simple and fast way, and its implementation by young surgeons. Pig models have been used in which collections made by bovine small intestine and simulated tumor lesions have been placed. Several types of image-guided procedures have been performed. No major complications were found during the development of the model or during its use. It is possible to develop a quick, simple, and safe living training model that can be used immediately after preparation.

Few studies have compared the surgical outcomes of laparoscopic (LG) and open (OG) gastrectomy in obese patients (BMI≥30 kg/m) with gastric cancer. The current study aimed to investigate the short-term outcomes of LG in this group of patients.

Choledochocystolithiasis and its associated complications such as cholangitis and pancreatitis are managed by endoscopic retrograde cholangiography (ERC), with endoscopic stone extraction followed by laparoscopic cholecystectomy (LC). However, affected patients present with complex conditions linked to operative difficulties in performing LC. The aim of this study was to elucidate the predictive factors for a prolonged LC procedure following ERC for treating patients with choledochocystolithiasis.
