Background Laparoscopic distal gastrectomy (LDG) for gastric cancer has been progressed and popular in Japan, since it was first described in 1994. Several reconstruction methods can be adopted according to remnant stomach size, and balance of pros and cons. Roux-en-Y (R-Y) reconstruction is a one of standard options after LDG. Its complications include Petersen's hernia and Roux stasis syndrome. Here we report our ingenious attempt, fixation of Roux limb and duodenal stump, for decreasing the development of Petersen's hernia and Roux stasis syndrome. Aim To develop a method to decrease the development of Petersen's hernia and Roux stasis syndrome. Methods We performed ante-colic R-Y reconstruction after LDG. After R-Y reconstruction, we fixed Roux limb onto the duodenal stump in a smooth radian. Via this small improvement in Roux limb, Roux limb was placed to the right of the ligament of Treitz. This not only changed the anatomy of the Petersen's defect, but it also kept a fluent direction of gastrointestinal anastomosis and avoided a cross-angle after jejunojejunostomy. 31 patients with gastric cancer was performed this technique after R-Y reconstruction. Clinical parameters including clinicopathologic characteristics, perioperative outcomes, postoperative complication and follow-up data were evaluated. Results The operative time was (308.0 ± 84.6 min). This improvement method took about 10 min. Two (6.5%) patients experienced pneumonia and pancreatitis, respectively. No patient required reoperation or readmission. All patients were followed up for at least 3 year, and none of the patients developed postoperative complications related to internal hernia or Roux stasis syndrome. Conclusion This 10 min technique is a very effective method to decrease the development of Petersen's hernia and Roux stasis syndrome in patients who undergo LDG.

Introduction A transorally inserted anvil has been developed to facilitate the creation of a stapled anastomosis without the need for a purse string to secure the anvil into place during laparoscopic total gastrectomy (LTG). We describe a hemi-double stapling technique and application of a transorally inserted anvil for esophagojejunostomy during LTG, and we report the results of a retrospective study in which we examined the feasibility and safety of this method. We also describe the key technical details of the method. Methods Our anastomotic method has four chief features: (a) the esophagus is cut at a slant, and its left cut end is cut and punched for the hemi-double stapling technique; (b) the anvil and circular stapler are connected, placing the distal jejunum in cranial traction; (c) a single layer of sutures is used to correct dog-earing and overlapping, and these points are completely closed with Lembert sutures; and (d) the jejunal limb is fixed to the duodenal stump to prevent kinking of the jejunal limb and to decrease tension on the anastomosis. Results This method has been used in 53 patients thus far. LTG with Roux-en-Y reconstruction was successful in all patients, and there was no need for conversion to open surgery. The mean operative time was 313 minutes, and the mean blood loss was 106 mL. The mean postoperative hospital stay was 18 days. There was no anastomotic leakage or stenosis. Conclusion Hemi-double stapling technique with a transorally inserted anvil for LTG can be performed safely and easily and safely. It can also product good outcomes.

Summary: Background: Billroth Ⅰ (BⅠ) reconstruction and Roux-en-Y (RY) reconstruction are both commonly performed after distal gastrectomy (DG). We conducted a retrospective study to evaluate which is the better option. Methods: Included in our study were 162 patients who, between April 2011 and October 2015, underwent DG followed by BⅠ reconstruction (n = 93) or RY reconstruction (n = 69). All patients were followed up for at least 1 year. We compared perioperative outcomes, postoperative complications, gastrointestinal (GI) symptoms, endoscopic findings, and nutritional status between the 2 groups of patients. Results: Patient characteristics did not differ between the 2 groups, with the exception of the incidence of gastric body tumors, which was significantly higher in the RY group (73.9% vs. 19.4%; p

Billroth I reconstruction is a means of anastomosis that is widely performed after surgical resection for distal gastric cancer. Interest has grown in totally laparoscopic gastrectomy, and several methods for totally laparoscopic performance of Billroth I reconstruction have been reported. However, the methods are cumbersome, and postoperative complications such as twisting at the site of anastomosis and obstruction due to stenosis have arisen. We developed an augmented rectangle technique (ART) by which the anastomosis is created laparoscopically with the use of three automatic endoscopic linear staplers, and the resulting anastomotic opening is wide and less likely to become twisted or stenosed. The technical details of our ART-based Billroth I anastomosis are presented herein along with results of the procedure to date. The technique was applied in 160 patients who underwent totally laparoscopic distal gastrectomy for gastric cancer between December 2013 and August 2017. Clinicopathological data, surgical data, and postoperative outcomes were analyzed. During surgery, there were no troubles associated with gastrointestinal reconstruction and there was no transition to laparotomy. There were no postoperative complications, including suture failure and stenosis, associated with the gastrointestinal reconstruction, and the average postoperative hospital stay was 12 days. Totally laparoscopic ART-based Billroth I reconstruction is both feasible and safe. We expect this technique to contribute to the spread of safe totally laparoscopic surgery for gastric cancer.

Background Esophagogastric anastomosis performed after esophagectomy is technically complex and often the source of postoperative complications. The best technique for this anastomosis remains a matter of debate. We describe a new all-stapled side-to-side anastomosis, which we refer to as triple-stapled quadrilateral anastomosis (TRIQ), that can be performed after minimally invasive surgery, and we report results of a retrospective evaluation of postoperative outcomes among the 60 patients in whom this anastomosis has been performed thus far. Methods The anastomosis is created by apposition of the posterior walls of the esophagus and stomach. A linear stapler is applied to create a V-shaped posterior anastomotic wall. The anterior wall is closed in a gentle chevron-like shape with the use of 2 separate linear staplers, resulting in a wide quadrilateral anastomosis. The anastomosis is then wrapped with a greater omentum flap. Results The patient group comprised 48 men and 12 women with a mean age of 67.8 years. Neoadjuvant chemotherapy was performed in 43 of these patients. Neither the thoracoscopic or laparoscopic procedure was converted to open surgery in any patient. The median operation time was 474 min (range 680–320 min). The intraoperative blood loss volume was 104.4 mL (range 240–30 mL). There were no anastomosis-related complications above Clavien-Dindo grade II. Conclusions TRIQ can be performed easily and safely, and good short-term outcome can be expected.

Background The rapid expansion of laparoscopic gastrectomy (LG) for gastric cancer has generated interest among surgeons. The adequate dissemination of correct information about such advanced laparoscopic surgery can certainly be useful for surgeons and trainees. Online video resources such as YouTube are frequently used for education. This study aimed to evaluate the quality, utility, and completeness of LG videos for gastric cancer on the video website YouTube. Methods The terms "laparoscopic gastrectomy" and "gastric cancer" were searched on YouTube on August 16, 2019. The first 100 videos in three sorting categories (website's default setting, view count, and length of duration) were checked by two experienced surgeons. The popularity was evaluated with the video power index (VPI). The reliability was measured using the Journal of American Medical Association (JAMA) benchmark criteria. The educational value and completeness were evaluated with a checklist developed by the researchers. Results A total of 102 videos were analyzed. Laparoscopic distal gastrectomy (LDG) and laparoscopic total gastrectomy were the most frequently recorded techniques. Lymph node (LN) dissection was the most frequently covered topic (89.2%), followed in descending order by GI reconstruction (87.3%). The mean VPI, JAMA benchmark score and completeness score of all videos were 2.63, 1.94 and 8.53, respectively. The types of sources were as follows: private users, 73 (71.6%); academic institutions, 20 (19.6%); and others, 9 (8%). A total of 97 videos with an identifiable primary surgeon originated from eighteen different countries. Conclusions Laparoscopic videos represented by YouTube represent a useful and appropriate educational tool. However, the quality of videos varied, and the level of information incompleteness was fairly high due to insufficient reviews. The role of private uploaders and academic institutions in surgical education cannot be overestimated. It is necessary that surgeon trainers and surgical educators critically analyze the quality of video content and exercise responsibility in directing trainee surgeons. In the current era, it is best for trainees to search for peer-reviewed content.

Background and Aim: Surgical site infection (SSI) remains an important concern in Japan. The Japanese Soci‐ ety for Infection and Prevention Control disclosed that the incidence of SSIs has been lowered only by a fraction over the past 10 years. The importance of taking steps to reduce the occurrence of SSIs is recognized by many hospitals, but to date, no truly effective countermeasures have been reported. We executed a plan to better un‐ derstand the spec fic surveillance needs at St. Marianna University School of Medicine Hospital and then de‐ velop and institute procedures that would reduce the incidence of SSIs. Methods and Results: In 2005, we began development of an enhanced SSI surveillance system. With our basic CDC-based surveillance system in place, we assembled a team of doctors and nurses to oversee surveillance. We practiced strict record keeping and data analysis, gleaned information from staff, and enlisted the coopera‐ tion of other departments. New procedures were established accordingly and implemented in three phases. Be‐ tween 2005 and 2013, we witnessed informative fluctuat ons in the incidence of SSIs. Key components of our new system were standardized postoperative wound cleansing, use of buried absorbable sutures to close surgical wounds, consistent provision of 6 antibacterial agents, each one active against a common organ spec fic patho‐ gen, and establishment of a prophylactic protocol. New methods of information sharing were also instituted. We lowered the incidence of SSIs from 8% in 2006 to approximately 6.9% in 2012. We continue to monitor the number of SSIs occurring and are encouraged by a steady decline. Conclusion: Establishment of the SSI team at our hospital has proven to be a useful multidisciplinary approach to nosocomial infection awareness and control. Gradual introduction of the system to the various departments and step-by-step implementation have decreased the occurrence of SSIs and the nosocomial spread of infectious agents.
