“…In the beginning, needle devices were not generally used in laparoscopic surgery because of the drawbacks of the instruments, such as shaft rigidity, weak grasping power, and small jaw size. However, newer generation needlescopic instruments, including the BJ needle, have overcome the drawbacks with more reliable holding power and less shaft bending 22‐24 …”

Introduction Single‐incision laparoscopic gastrectomy can be difficult because of complex instrumentation and a limited working angle. We standardized a needle device‐assisted single‐incision laparoscopic gastrectomy (NA‐SILG) procedure for early gastric cancer in 2013. Herein, we present our technique and evaluate it in comparison to the conventional laparoscopic gastrectomy CLG) technique. Methods We retrospectively reviewed medical records of 149 patients who underwent a NA‐SILG or distal (CLG) for early gastric cancer between January 2013 and August 2016. We performed 1:1 propensity score matching between the two groups. Results Eighteen patients who underwent a NA‐SILG and 131 who underwent a CLG were included. Almost all patients were in clinical stage IA. Operative times were 216 ± 29.7 minutes and 220 ± 51.7 minutes for the NA‐SILG and CLG groups, respectively; the median intraoperative bleeding amounts were 5 mL and 10 mL for the NA‐SILG and CLG groups, respectively. The median number of retrieved lymph nodes was 41.5 and 57 for the NA‐SILG and CLG groups, respectively. The number of patients needing analgesics was significantly lower in the NA‐SILG group (P = .003) than in the CLG group. Neither group had postoperative complications more severe than Clavien‐Dindo classification III. Conclusion Needle device‐assisted SILG is safe and feasible for early gastric cancer treatment in slim figure patients. It has short and long‐term outcomes comparable to the CLG but is less invasive and results in less postoperative pain.

Objective: Minimally invasive gastrectomy is performed worldwide because it confers less stress and pain for patients with gastric cancer. Recently, other types of minimally invasive gastrectomy, which include robotic gastrectomy, have also been developed. In this paper, we will review the history, current status, and future prospects of minimally invasive gastrectomy. Methods:We overviewed gastric cancer and reviewed the outcomes of previous clinical trials. In addition, we present our newly developed technique of minimally invasive gastrectomy, especially for anastomosis. Results: Previous clinical trials showed that minimally invasive gastrectomy was similar or superior to open gastrectomy in terms of short-term results, while minimally invasive gastrectomy was not superior to open gastrectomy in terms of long-term survival. Many studies have reported that postoperative complications could induce cancer recurrence; hence, we hypothesize that the survival of patients who underwent minimally invasive gastrectomy will be better than that of patients who underwent open gastrectomy. An intracorporeal anastomosis might help decrease the incidence of postoperative complication because it can shorten the length of surgical incisions. However, this procedure requires experienced skilled surgeons. Conclusion:The surgical system of minimally invasive gastrectomy, including robotic gastrectomy, has dramatically improved. Although there are challenges that need to be addressed, we believe that using more advanced technology or equipment will make minimally invasive gastrectomy the standard treatment for gastric cancer in the future.

“…In order to preserve the entire stomach of the patients with a tumor at EGJ the authors have been performing percutaneous endoscopic intragastric surgery (PEIGS) since 1993 and have reported its fair outcomes (4)(5)(6)(7). Moreover, in addition to the original method of PEIGS, we have recently developed further cosmetic procedures such as single incision PEIGS (5,6) and needlescopic PEIGS (7). Herein we demonstrate the techniques of the three different types of PEIGS, which should play an important role as an organ preserving surgery in the treatment of gastric submucosal tumors.…”

As an organ preserving option in the treatment of submucosal tumor found at the esophagogastric junction (EGJ), percutaneous endoscopic intragastric surgery (PEIGS) plays an important role, while it is not commonly performed and there have been very few reports on this unique operation. The current authors have been performing PEIGS since 1993 and have reported on its short- and long-term outcomes from one of the world largest series. Herein its confusing terminology is discussed and techniques of three different types of PEIGS (original PEIGS, single incision PEIGS, and needlescopic PEIGS) are precisely described. Although reports on clinical outcomes of PEIGS have been rarely published, both short-term and long-term outcomes seem acceptable, as far as we review our own experiences and the past literatures. PEIGS needs to be accessed by the data from larger series or RCT to be further justified and spread for the patients with submucosal tumors at EGJ to salvage their stomach.
