| 1 | Minimally invasive surgery for upper gastrointestinal cancer: Our experience and review of the literature显示文摘Minimally invasive surgery(MIS) for upper gastro-intestinal(GI) cancer, characterized by minimal access, has been increasingly performed worldwide. It not only results in better cosmetic outcomes, but also reduces intraoperative blood loss and postoperative pain, leading to faster recovery; however, endoscopically enhanced anatomy and improved hemostasis via positive intracorporeal pressure generated by CO2 insufflation have not contributed to reduction in early postoperative complications or improvement in long-term outcomes. Since 1995, we have been actively using MIS for operable patients with resectable upper GI cancer and have developed stable and robust methodology in conducting totally laparoscopic gastrectomy for advanced gastric cancer and prone thoracoscopic esophagectomy for esophageal cancer using novel technology including da Vinci Surgical System(DVSS). We have recently demonstrated that use of DVSS might reduce postoperative local complications including pancreatic fistula after gastrectomy and recurrent laryngeal nerve palsy after esophagectomy. In this article, we present the current status and future perspectives on MIS for gastric and esophageal cancer based on our experience and a review of the literature. | Koichi Suda Masaya Nakauchi Kazuki Inaba Yoshinori Ishida Ichiro Uyama | 2016 | World Journal of Gastroenterology2016,22,19: | 13 |
| 2 | Non-robotic minimally invasive gastrectomy as an independent risk factor for postoperative intra-abdominal infectious complications: A single-center, retrospective and propensity score-matched analysis显示文摘BACKGROUND Minimally invasive surgery for gastric cancer(GC) has gained widespread use as a safe curative procedure especially for early GC.AIM To determine risk factors for postoperative complications after minimally invasive gastrectomy for GC.METHODS Between January 2009 and June 2019, 1716 consecutive patients were referred to our division for primary GC. Among them, 1401 patients who were diagnosed with both clinical and pathological Stage Ⅲ or lower GC and underwent robotic gastrectomy(RG) or laparoscopic gastrectomy(LG) were enrolled. Retrospective chart review and multivariate analysis were performed for identifying risk factors for postoperative morbidity.RESULTS Morbidity following minimally invasive gastrectomy was observed in 7.5% of the patients. Multivariate analyses demonstrated that non-robotic minimally invasive surgery, male gender, and an operative time of ≥ 360 min were significant independent risk factors for morbidity. Therefore, morbidity was compared between RG and LG. Accordingly, propensity-matched cohort analysis revealed that the RG group had significantly fewer intra-abdominal infectious complications than the LG group(2.5% vs 5.9%, respectively;P = 0.038), while no significant differences were noted for other local or systemic complications.Multivariate analyses of the propensity-matched cohort revealed that non-robotic minimally invasive surgery [odds ratio = 2.463(1.070–5.682);P = 0.034] was a significant independent risk factor for intra-abdominal infectious complications.CONCLUSION The findings showed that robotic surgery might improve short-term outcomes following minimally invasive radical gastrectomy by reducing intra-abdominal infectious complications. | Susumu Shibasaki Koichi Suda Masaya Nakauchi Kenichi Nakamura Kenji Kikuchi Kazuki Inaba Ichiro Uyama | 2020 | World Journal of Gastroenterology2020,26,11: | 8 |

| 5 | Laparoscopic repair of hiatal hernia with mesenterioaxial volvulus of the stomach显示文摘Although mesenterioaxial gastric volvulus is an uncommon entity characterized by rotation at the transverse axis of the stomach, laparoscopic repair procedures have still been controversial. We reported a case of mesenterioaxial intrathoracic gastric volvulus, which was successfully treated with laparoscopic repair of the diaphragmatic hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication. A 70-year-old Japanese woman was admitted to our hospital because of sudden onset of upper abdominal pain. An upper gastrointestinal series revealed an incarcerated intrathoracic mesenterioaxial volvulus of the distal portion of the stomach and the duodenum. The complete laparoscopic approach was used to repair the volvulus. The laparoscopic procedures involved the repair of the hiatal hernia using polytetrafluoroethylene mesh and Toupet fundoplication. This case highlights the feasibility and effectiveness of the laparoscopic procedure, and laparoscopic repair of the hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication may be useful for preventing postoperative recurrence of hiatal her-nia, volvulus, and gastroesophageal reflux. | Kazuki Inaba Yoichi Sakurai Jun Isogaki Yoshiyuki Komori Ichiro Uyama | 2011 | World Journal of Gastroenterology2011,17,15: | 3 |

| 8 | Prognostic factors of minimally invasive surgery for gastric cancer: Does robotic gastrectomy bring oncological benefit?显示文摘BACKGROUND Gastric cancer is the third leading cause of cancer-related death worldwide and surgical resection remains the sole curative treatment for gastric cancer.Minimally invasive gastrectomy including laparoscopic and robotic approaches has been increasingly used in a few decades.Thus far,only a few reports have investigated the oncological outcomes following minimally invasive gastrectomy.AIM To determine the 5-year survival following minimally invasive gastrectomy for gastric cancer and identify prognostic predictors.METHODS This retrospective cohort study identified 939 patients who underwent gastrectomy for gastric cancer during the study period.After excluding 125 patients with non-curative surgery(n=77),other synchronous cancer(n=2),remnant gastric cancer(n=25),insufficient physical function(n=13),and open gastrectomy(n=8),a total of 814 consecutive patients with primary gastric cancer who underwent minimally invasive R0 gastrectomy at our institution between 2009 and 2014 were retrospectively examined.Accordingly,5-year overall and recurrence-free survival were analyzed using the Kaplan–Meier method with the log-rank test and Cox regression analyses,while factors associated with survival were determined using multivariate analysis.RESULTS Our analysis showed that age>65 years,American Society of Anesthesiologists(ASA)physical status 3,total or proximal gastrectomy,and pathological T4 and N positive status were independent predictors of both 5-year overall and recurrencefree survival.Accordingly,the included patients had a 5-year overall and recurrence-free survival of 80.3%and 78.2%,respectively.Among the 814 patients,157(19.3%)underwent robotic gastrectomy,while 308(37.2%)were diagnosed with pathological stage II or III disease.Notably,our findings showed that robotic gastrectomy was an independent positive predictor for recurrence-free survival in patients with pathological stage II/III[hazard ratio:0.56(0.33-0.96),P=0.035].Comparison of recurrence-free survival between the robotic and laparoscopic approach using propensity score matching analysis verified that the robotic group had less morbidity(P=0.005).CONCLUSION Age,ASA status,gastrectomy type,and pathological T and N status were prognostic factors of minimally invasive gastrectomy,with the robot approach possibly improving long-term outcomes of advanced gastric cancer. | Masaya Nakauchi Koichi Suda Susumu Shibasaki Kenichi Nakamura Shinichi Kadoya Kenji Kikuchi Kazuki Inaba Ichiro Uyama | 2021 | World Journal of Gastroenterology2021,27,39: | 1 |

| 12 | Preparation of Lanthanum Nickel Oxide-Coated Ni Sheet Anodes and Their Application to Electrolytic Production of (CF_3)_3N in (CH_3)_4NF·4.0HF Melt显示文摘A new process for electrolytic production of a perfluorinated compound, (CF3)3N, using lanthanum nickel oxide-coated Ni sheet anode in the (CH3)4NF·4.0HF melt at room temperature, was developed. Thin films of the lanthanum nickel oxides were prepared on Ni sheets by sol-gel coating method using polyvinlylpyrrolidone(PVP). The main components of the thin films were La2O3, LaNiO3, and La2NiO4 at 500, 750 and 1000 ℃, respectively. The anode performance in the (CH3)4NF·4.0HF melt depends greatly on the main component of the thin film, and the LaNiO3-coated Ni sheet anode gives the best anode performance. The potential of LaNiO3-coated Ni sheet anode remains constant at 5.9 V during electrolysis at 20 mA·cm -2 in the (CH3)4NF·4.0HF melt for 100 h. This is because LaNiO3 and NiF3 and/or Ni2F5, the latter of which was formed during electrolysis, in the film give a high electronic conductivity to the surface film during electrolysis. The maximum mole fraction of (CF3)3N (21.4%) was obtained at 20 mA·cm -2 in (CH3)4NF·4.0HF melt using the LaNiO3-coated Ni sheet. | Yoshio Shodai Minoru Inaba Kazuki Onoda Akimasa Tasaka | 2006 | Journal of Rare Earths2006,24,1: | 1 |
