Abstract
BACKGROUND AND OBJECTIVES Robotic distal gastrectomy (RDG) has been widely performed throughout Japan since it became insured in 2018. This study aimed to evaluate the short-term outcomes of RDG and laparoscopic distal gastrectomy (LDG) for gastric cancer using real-world data. METHODS A total of 4161 patients who underwent LDG (n = 3173) or RDG (n = 988) for gastric cancer between April 2018 and October 2022 were identified through the Japanese Diagnosis Procedure Combination Database, which covers 42 national university hospitals. The primary outcome was postoperative in-hospital mortality rate. The secondary outcomes were postoperative complication rates, time to diet resumption, and postoperative length of stay (LOS). RESULTS In-hospital mortality and postoperative complication rates in the RDG group were comparable with those in the LDG group (0.1% vs. 0.0%, p = 1.000, and 8.7% vs. 8.2%, p = 0.693, respectively). RDG was associated with a longer duration of anesthesia (325 vs. 262 min, p < 0.001), similar time to diet resumption (3 vs. 3 days, p < 0.001), and shorter postoperative LOS (10 vs. 11 days, p < 0.001) compared with LDG. CONCLUSIONS RDG was performed safely and provided shorter postoperative LOS, since it became covered by insurance in Japan.

Abstract
The incidence of gastric tube cancers has increased due to improved survival rates in patients after esophagectomy. However, the optimal surgical approach for gastric tube cancer remains controversial. Here, we report the case of a 70-year-old man with advanced gastric cancer arising from a retrosternally placed gastric conduit, 12 years after thoracic esophagectomy for esophageal cancer. Total resection of the gastric conduit was performed with robotic assistance. Although the working space was limited, secure resection was possible. Continuous en bloc mobilization was achieved with neck dissection, and reconstruction was performed via the same retrosternal route using the ileocolon. The patient was discharged on the 14th postoperative day without any adverse events. Robot-assisted surgery can overcome the technical limitations of laparoscopic mediastinal surgery and has advantages such as improved ergonomics, comfort, and elimination of hand tremors, and therefore may be an option for future minimally invasive surgeries.

The application of enhanced recovery after surgery in minimally invasive gastrectomy for gastric cancer: a meta-analysis of randomized controlled trials. Expert Rev Gastroenterol Hepatol 2022; 16:1089-1100. [PMID: 36354134 DOI: 10.1080/17474124.2022.2145944] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/11/2022]
Abstract
OBJECTIVE We aimed to investigate the efficacy and safety of enhanced recovery after surgery (ERAS) for patients with gastric cancer undergoing minimally invasive surgery (MIS). METHODS We searched the PubMed, Cochrane Library, Web of Science, Embase, CNKI, VIP, WanFang, and CBM for relevant RCTs from the database inception until December 2021, for studies that compared the ERAS and traditional care (TC) in MIS for gastric cancer. RESULTS A total of 25 RCTs comprising 2809 patients were included in this study. When compared with the traditional care TC group, the ERAS group had a shorter postoperative hospital stay [MD = -1.88,95%CI (-2.22, -1.55), P < 0.00001] and an earlier time at first postoperative flatus [MD = -18.12,95%CI (-21.45,-14.80), P < 0.00001] along with lower medical costs [SMD = -0.64, 95% CI (-0.85, -0.43), P < 0.00001] and an overall reduction in postoperative complication rates [RR = 0.55, 95% CI (0.44, 0.69), P < 0.00001]. However, the difference in the readmission rates was not significant. CONCLUSIONS ERAS can shorten the postoperative hospital stay, hasten the first postoperative flatus and reduce medical costs and overall postoperative complication rate without increasing readmission rates. Therefore, the ERAS protocol is preferable for gastric cancer patients undergoing MIS.

Abstract
The number of operations performed using the da Vinci Surgical System® (DVSS) has been increasing worldwide in the past decade. We introduced robotic gastrectomy for gastric cancer (GC) in January 2009 to overcome the disadvantage of conventional laparoscopic gastrectomy. Initially, we experienced some troubles in the technical aspect and cost of robotic surgery. After extensive trial and error, we were able to develop the "double bipolar method" and the "da Vinci's plane theory" to use DVSS effectively. We then conducted "Senshiniryo B," which was a multi-institutional prospective single-arm study to determine the safety, feasibility, and effectiveness of robotic gastrectomy for GC in 2014. In that study, we demonstrated that the morbidity rate in the robotic group (2.45%) was significantly lower than that in the historical control group (6.4%). As a consequence of that clinical trial, 12 procedures, including robotic gastrectomy for GC, have been covered under the Japanese national insurance in 2018. An additional seven procedures were newly covered in April 2020. In the first half of this article, we describe the history of robotic surgery in the world and Japan and demonstrate the "double bipolar method" and "da Vinci's plane theory." In the latter half, we explain the Japanese systems for the safe dissemination of robotic surgery and state our efforts to solve some problems in robotic surgery.

Abstract
Anastomotic leakage, including cervical anastomotic leakage and intrathoracic anastomotic leakage, is a serious complication of esophageal cancer and a leading cause of death after esophagectomy. In fact, anastomotic leakage after esophagectomy can be caused by numerous factors in the preoperative, intraoperative, and postoperative periods. Intraoperative technique-related risk factors, including surgical methods, anastomosis sites, anastomosis methods, the type of gastric tube, and reconstruction routes, are the key causes of its occurrence. Anastomotic leakage treatments include both surgical and non-surgical treatments, while surgical treatment has high risks, many complications, and high mortality. Actually, non-surgical methods including naso-leakage drainage, stent, negative pressure therapy, and so on, are also very critical in the treatment of anastomotic leakage. So, the selection of correct and appropriate treatment methods plays an important role in alleviating the suffering of patients, shortening hospitalization time, and reducing mortality. This study undertook a systematic review in which data in the PubMed database were searched and analyzed to assess the safety and efficacy of surgical technique-related factors in esophagectomy, and appropriate treatment of anastomotic leakage after esophagectomy. In conclusion, gastric tube, posterior mediastinal route and stapled anastomosis are safe among esophagectomy surgical techniques, and non-surgical treatment of anastomotic leakage such as naso-leakage drainage is feasible in the majority of cases.

Abstract
Surgeons have increased physical stress during laparoscopic surgery due to operative site constraints. We developed a wearable device to reduce the physical stress on surgeons' lower extremities. The device mechanically facilitates maintaining a near-upright posture. The surgeon's knees are gently bent by a knee-joint locking mechanism, and fixing and releasing are performed independently on each side. The subjects were one female and two male surgeons, who wore the device during laparoscopic inguinal hernia repair or high anterior resection. Surface electromyogram (EMG) was conducted for both iliopsoas muscles. Control values were determined with the subject not wearing the device. Participants completed a post-procedure questionnaire. With the device, EMG activity had a tendency to decrease in the left iliopsoas muscle (P = .055), but it changed little on the right (P = .406). The post-procedure questionnaire showed an overall positive impression, although subjects reported some difficulty walking. This device decreases EMG activity and may improve a surgeon's work environment.

Quantification of fluorescence angiography: Toward a reliable intraoperative assessment of tissue perfusion - A narrative review. Langenbecks Arch Surg 2020; 406:251-259.

Abstract
BACKGROUND Accurate intraoperative assessments of tissue perfusion are essential in all forms of surgery. As traditional methods of perfusion assessments are not available during minimally invasive surgery, novel methods are required. Here, fluorescence angiography with indocyanine green has shown promising results. However, to secure objective and reproducible assessments, quantification of the fluorescent signal is essential (Q-ICG). This narrative review aims to provide an overview of the current status and applicability of Q-ICG for intraoperative perfusion assessment. RESULTS Both commercial and custom Q-ICG software solutions are available for intraoperative use; however, most studies on Q-ICG have performed post-operative analyses. Q-ICG can be divided into inflow parameters (ttp, t0, slope, and T1/2max) and intensity parameters (Fmax, PI, and DR). The intensity parameters appear unreliable in clinical settings. In comparison, inflow parameters, mainly slope, and T1/2max have had superior clinical performance. CONCLUSION Intraoperative Q-ICG is clinically available; however, only feasibility studies have been performed, rendering an excellent usability score. Q-ICG in a post-operative setting could detect changes in perfusion following a range of interventions and reflect clinical endpoints, but only if based on inflow parameters. Thus, future studies should include the methodology outlined in this review, emphasizing the use of inflow parameters (slope or T1/2max), a mass-adjusted ICG dosing, and a fixed camera position.

Abstract
Robotic gastrectomy (RG) using the da Vinci Surgical System for gastric cancer was approved for national medical insurance coverage in Japan in April, 2018, and has been used increasingly since. We reviewed the current evidence on RG, open gastrectomy (OG), and conventional laparoscopic gastrectomy (LG) to identify differences in surgical outcomes between Japan and other countries. Briefly, three independent reviewers systematically reviewed the data collected from a comprehensive literature search by an independent organization and focused on the following nine endpoints: mortality, morbidity, operative time, estimated volume of blood loss, length of postoperative hospital stay, long-term oncologic outcome, quality of life, learning curve, and cost. Overall, the mortality rate of the three approaches did not differ, but RG and LG had less intraoperative blood loss and resulted in a shorter postoperative hospital stay than OG. RG had longer operative times and incurred higher costs than LG and OG. However, in Japan, RG may be more effective than LG and OG for decreasing morbidity. Further studies are needed to establish the specific indications for RG, optimal robotic setup, and dissection methods to best utilize the surgical robot.

Laparoscopic distal gastrectomy for gastric cancer patient with intestinal malrotation: report of a case. Surg Case Rep 2019; 5:45.

Abstract
Background Intestinal malrotation, which arises from incomplete rotation of the embryonic midgut, is one of the congenital anomalies usually diagnosed in infancy. On the other hand, intestinal malrotation detected in asymptomatic adults is very rare. It is frequently diagnosed incidentally during abdominal surgery. We report a case of asymptomatic intestinal malrotation diagnosed during laparoscopic distal gastrectomy for gastric cancer. Case presentation A 59-year-old female was diagnosed with early-stage gastric cancer during health screening and admitted to our hospital for radical surgical treatment. Physical examinations and blood tests revealed nothing of note. The type 0-IIc gastric cancer was located in the posterior wall of the mid-body of the stomach. The histological type was poorly differentiated adenocarcinoma. Esophagogastroduodenoscopy and computed tomography (CT) suggested that the depth of tumor invasion was the submucosal layer without regional lymph node swelling. The clinical stage according to the TNM 7th edition was cT1b N0 M0, cStage I. Laparoscopic distal gastrectomy with D1+ lymph node dissection and Billroth-I method reconstruction was planned. During the infrapyloric lymph node dissection, a part of the pancreatic head showed unusual adherence to the first part of the duodenal wall. For safe and accurate lymphadenectomy while avoiding pancreatic injury, we deliberately focused on tracing the dissectible layer between the pancreatic parenchyma and fatty tissues including lymph nodes. Also, we changed the reconstruction procedure from Billroth-I to Roux-en-Y. After distal gastrostomy, we could not find the ligament of Treitz or jejunum on the left side below the transverse colon. Based on a review of the CT image, this patient was diagnosed with intestinal malrotation. Although the detection of malrotation during the operation was incidental, we could complete radical surgery and Roux-en-Y reconstruction safely. The type of malrotation was non-rotation (90°). She was discharged from our hospital without any complications. Conclusion We encountered a case of adult asymptomatic intestinal malrotation with gastric cancer. Even when encountering such a case during laparoscopic gastrectomy, reviewing CT images carefully to reconsider the anatomical anomalies, and tracing the dissectible layer accurately with adequate countertraction can facilitate safe and successful surgery.

Abstract
Technical advances and developments in endoscopic equipment and thoracoscopic surgery have increased the popularity of minimally invasive esophagectomy (MIE). However, there is currently no established scientific evidence supporting the use of MIE as an alternative to open esophagectomy (OE). To date, a number of single-institution studies and several meta-analyses have demonstrated acceptable short-term outcomes of thoracoscopic esophagectomy for esophageal cancer, and we recently reported one of the largest propensity score-matched comparison studies between MIE and OE for esophageal cancer, based on a nationwide Japanese database. We found that, in general, MIE had a longer operative time and less blood loss than OE. Moreover, compared to OE, MIE was associated with a lower rate of pulmonary complications such as pneumonia, and both methods had similar mortality rates. Although MIE may reduce the occurrence of postoperative respiratory complications, MIE and OE seem to have comparable short-term outcomes. However, the oncological benefit to patients undergoing MIE remains to be scientifically proven, as no randomized controlled trials have been conducted to verify each method's impact on the long-term survival of cancer patients. An ongoing randomized phase III study (JCOG1409) is expected to determine the impact of each method with regard to short- and long-term outcomes.

Abstract
The 11th edition of the Japanese Classification of Esophageal Cancer (EC) was published in 2017. Some correction was made in the depth of tumor invasion to be consistent with the TNM classification by the Union for International Cancer Control (UICC). With regard to surgery, short-term safety and long-term effectiveness under thoracotomy/video-assisted thoracoscopic surgery are expected to be proven by the Japan Clinical Oncology Group (JCOG)1409 study. Results of nutritional management and countermeasures for adverse events not only during the perioperative period but also during EC chemotherapy were reported. From now on, the pursuit of low invasiveness and radicality is desired. Esophageal surgery is also expected to be safe at all institutions. To determine the optimal modality of preoperative treatment and a novel chemo(radio)therapy regimen for patients with distant metastasis, the results of the ongoing JCOG1109 and 0807 studies are being released. The effect of the addition of molecular targeted drugs on chemotherapy and concurrent chemoradiation has not yet improved overall survival. Immune checkpoint inhibitor drugs could offer a potential new treatment approach for patients with treatment-refractory advanced squamous cell carcinoma (SCC). The Cancer Genome Atlas Research Network reported the results of a comprehensive genome analysis and molecular analysis of SCC and adenocarcinoma of the esophagus. Further differentiation of SCC and adenocarcinoma by molecular characterization analysis may be useful for the development of clinical trials and targeted drug therapies as precision medicine. The era of ultimate minimally invasive surgery and personalized treatment has begun. Large, prospective studies will be required to confirm the value of these advancements.

Abstract
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, with the majority found in the stomach. Surgical resection of the primary gastric GISTs with complete resection margin has been the forefront of curative treatment. The indications for surgical resection are usually related to symptomatic gastric GISTs at presentation. Primary gastric GISTs resection performed conventionally through an open surgery can now be frequently achieved by minimal invasive surgery with similar oncological outcome. Surgeon's selection of the type of surgical techniques such as open, laparoscopic and endoscopic resections depends on the site, size and local invasion of gastric GISTs to the adjacent organ. Similarly those factors dictate the extent of gastric resections in the form of wedge, partial or total gastrectomy. All these inherent tumor factors (size and mitotic index), patient factors (older age, male) and surgical factors (incomplete resection margin, tumor rupture or spillage) play an important role in stratifying the malignant potential risk of primary gastric GISTs and their chances of recurrence. The understanding of gene mutation driving the growth of GISTs and the discovery of tyrosine kinase inhibitors (TKIs) has altered the surgical management of advanced and metastatic GISTs. Multi-modal therapy incorporating the surgical resection of GISTs and utilizing the molecular targeted therapy in the adjuvant, neoadjuvant and palliative settings can offer optimal personalized outcome and prolong patient's overall survival (OS).
