Abstract
BACKGROUND Gastric cancer is one of the most common malignant tumors in the digestive system in China. Few comprehensive practice guidelines for early gastric cancer in China are currently available. Therefore, we created the Chinese national clinical practice guideline for the prevention, diagnosis, and treatment of early gastric cancer. METHODS This clinical practice guideline (CPG) was developed in accordance with the World Health Organization's recommended process and with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) in assessing evidence quality. We used the Evidence to Decision framework to formulate clinical recommendations to minimize bias and increase transparency in the CPG development process. We used the Reporting Items for practice Guidelines in HealThcare (RIGHT) statement and the Appraisal of Guidelines for Research and Evaluation II (AGREE II) as reporting and conduct guidelines to ensure completeness and transparency of the CPG. RESULTS This CPG contains 40 recommendations regarding the prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer based on available clinical studies and guidelines. We provide recommendations for the timing of Helicobacter pylori eradication, screening populations for early gastric cancer, indications for endoscopic resection and surgical gastrectomy, follow-up interval after treatment, and other recommendations. CONCLUSIONS This CPG can lead to optimum care for patients and populations by providing up-to-date medical information. We intend this CPG for widespread adoption to increase the standard of prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer; thereby, contributing to improving national health care and patient quality of life.

Abstract
Objectives Laparoscopic gastrectomy (LG) was challenging to most surgeons due to the two-dimensional view, difficult manipulations of the instruments, ergonomic discomfort, and the associated muscular spasm and effort. Technological advances with improved surgical experience, have made LG a more feasible and favorable approach for gastric cancer (GC) patients. Material and Methods LG was performed in 44 patients with GC between July 2015 to June 2022, in the Department of Surgical Oncology, Oncology Center, Mansoura University, Egypt, and we assessed the surgical outcomes of this approach as an initial experience of a single cancer center. Results Twenty-seven patients underwent laparoscopic distal gastrectomy, and seventeen underwent laparoscopic total gastrectomy. Two cases had combined resection. Operative time was 339.2 ± 76.73 min, while blood loss was 153.86 ± 57.51 mL. The patients were ambulant on postoperative day 0, oral intake was started within three days (range 1-5 days) and the hospital stay was six days (range 3-9 days). Conclusion LG for GC is a feasible approach for both early and advanced GC patients as it allows for adequate diagnosis of the peritoneal disease, meticulous dissection, and identification of the lymph nodes with minimal blood loss and decrease surgery-related problems and encourage the early patients' discharge from hospital and return to daily life activities.

Abstract
BACKGROUND Laparoscopic gastrectomy (LG) is widely accepted as a minimally invasive approach for the treatment of early gastric cancer. However, its role in locally advanced gastric cancer (LAGC) after neoadjuvant therapy (NAT) remains controversial. This study aimed to compare the efficacy and safety of LG vs open gastrectomy (OG) after NAT for the treatment of LAGC.
AIM To compare the efficacy and safety of LG vs OG after NAT for LAGC.
METHODS We conducted a prospective study of 76 patients with LAGC who underwent NAT followed by LG (n = 38) or OG (n = 38) between 2021 and 2023. The primary endpoint was overall survival (OS), and the secondary endpoints were disease-free survival (DFS), surgical complications, and quality of life (QOL).
RESULTS The two groups had comparable baseline characteristics, with a median follow-up period of 24 mo. The 3-year OS rates in the LG and OG groups were 68.4% and 60.5%, respectively (P = 0.42). The 3-year DFS rates in the LG and OG groups were 57.9% and 50.0%, respectively (P = 0.51). The LG group had significantly less blood loss (P < 0.001), a shorter hospital stay (P < 0.001), and a lower incidence of surgical site infection (P = 0.04) than the OG group. There were no significant differences in other surgical complications between the groups, including anastomotic leakage, intra-abdominal abscess, or wound dehiscence. The LG group had significantly better QOL scores than the OG group regarding physical functioning, role functioning, global health status, fatigue, pain, appetite loss, and body image at 6 months postoperatively (P < 0.05).
CONCLUSION LG after NAT is a viable and safe alternative to OG for the treatment of LAGC, with similar survival outcomes and superior short-term recovery and QOL. LG patients had less blood loss, shorter hospitalizations, and a lower incidence of surgical site infections than OG patients. Moreover, the LG group had better QOL scores in multiple domains 6 mo postoperatively. Therefore, LG should be considered a valid option for patients with LAGC who undergo NAT, particularly for those who prioritize postoperative recovery and QOL.

Abstract
BACKGROUND Laparoscopic liver resection (LLR) requires delicate skills. The aim of the study was to develop a training model mimicking as much as possible intraoperative bleeding and bile leakage during LLR. We also assessed the educational value of the training model. METHODS The Lap-liver trainer (LLT) combined a continuously pressurized ex situ cadaver liver and a customized mannequin. The customized mannequin was designed by computer-aided design and manufactured by 3D printing. The left lateral sectionectomy (LLS) was chosen to assess the feasibility of a LLR with the LLT. Eighteen volunteers were recruited to perform LLS and to assess the educational value of the LLT using a Likert scale. RESULTS The customized mannequin consisted of a close laparoscopic training device based on a simplified reconstruction of the abdominal cavity in laparoscopic conditions. Ex situ cadaver livers were pressurized to simulate blood and bile supplies. Each expert surgeon (n = 3) performed two LLS. They were highly satisfied of simulation conditions (4.80 ± 0.45) and strongly recommended that the LLT should be incorporated into a teaching program (5.00 ± 0.0). Eight novice and 4 intermediate surgeons completed a teaching program and performed a LLS. Overall, the level of satisfaction was high (4.92 ± 0.29), and performing such a procedure under simulation conditions benefited their learning and clinical practice (4.92 ± 0.29). CONCLUSIONS The LLT could provide better opportunities for trainees to acquire and practice LLR skills in a more realistic environment and to improve their ability to deal with specific events related to LLR.

Abstract
BACKGROUND D2 lymph node dissection for advanced gastric cancer is advocated, and station 8p lymph node should be considered in selected patients, which is, however, technically difficult.
AIM To introduce a new and easy-to-perform procedure for dissection of the lymph nodes superior to the pancreas.
METHODS A series of patients who underwent laparoscopic gastrectomy for gastric cancer were retrospectively included with utilization of a new procedure for superior pancreatic lymphadenectomy (LND) with portal vein priority via the posterior common hepatic artery approach (SPLD-PPPH) based on a newly defined portal triangle. The surgical outcome of the patients, as well as the efficacy and safety of SPLD-PPPH are reported.
RESULTS A total of 51 patients were included with most of them being male (n = 34, 66.7%). According to the 8th edition of AJCC TNM staging, there were four (7.8%) patients in stage I, 13 (25.5%) in stage II, 33 (64.7%) in stage III and one (2.0%) in stage IV. The average duration for LND was about 1 h (67.7 ± 6.9 min). After surgery, four patients developed morbidities, but all were treated successfully with no perioperative mortality. Among the 51 patients included, the percentage of patients who had lymph node metastasis at station 8p was 9.8%. Of note, with a total of 14 lymph nodes harvested at station 8p, the incidence of nodal metastasis was 14.3%.
CONCLUSION About one in 10 patients with advanced gastric cancer had nodal metastasis at station 8p. The new approach of SPLD-PPPH is safe and effective for D2+ LND during laparoscopic radical gastrectomy.

Abstract
The stomach exhibits abundant lymphatic flow, and metastasis to lymph nodes is common. In the case of gastric cancer, there is a regularity to the spread of lymph node metastasis, and it does not easily metastasize outside the regional nodes. Furthermore, when its extent is limited, nodal metastasis of gastric cancer can be cured by appropriate lymph node dissection. Therefore, identifying and determining the extent of lymph node metastasis is important for ensuring accurate diagnosis and appropriate surgical treatment in patients with gastric cancer. However, precise detection of lymph node metastasis remains difficult. Most nodal metastases in gastric cancer are microscopic metastases, which often occur in small-sized lymph nodes, and are thus difficult to diagnose both preoperatively and intraoperatively. Preoperative nodal diagnoses are mainly made using computed tomography, although the specificity of this method is low because it is mainly based on the size of the lymph node. Furthermore, peripheral nodal metastases cannot be palpated intraoperatively, nodal harvesting of resected specimens remains difficult, and the number of lymph nodes detected vary greatly depending on the skill of the technician. Based on these findings, gastrectomy with prophylactic lymph node dissection is considered the standard surgical procedure for gastric cancer. In contrast, several groups have examined the value of sentinel node biopsy for accurately evaluating nodal metastasis in patients with early gastric cancer, reporting high sensitivity and accuracy. Sentinel node biopsy is also important for individualizing and optimizing the extent of uniform prophylactic lymph node dissection and determining whether patients are indicated for function-preserving curative gastrectomy, which is superior in preventing post-gastrectomy symptoms and maintaining dietary habits. Notably, advancements in surgical treatment for early gastric cancer are expected to result in individualized surgical strategies with sentinel node biopsy. Chemotherapy for advanced gastric cancer has also progressed, and conversion gastrectomy can now be performed after downstaging, even in cases previously regarded as inoperable. In this review, we discuss the importance of determining lymph node metastasis in the treatment of gastric cancer, the associated difficulties, and the need to investigate strategies that can improve the diagnosis of lymph node metastasis.

Laparoscopic gastrectomy for gastric cancer: has the time come for considered it a standard procedure? Surg Oncol 2022; 40:101699.

Abstract
Radical gastrectomy with an adequate lymphadenectomy is the main procedure which makes it possible to cure patients with resectable gastric cancer. A number of randomized controlled trials and meta-analysis provide phase III evidence that laparoscopic gastrectomy is technically safe and that it yields better short-term outcomes than conventional open gastrectomy for early-stage gastric cancer. At present, laparoscopic gastrectomy is considered a standard procedure for early-stage gastric cancer, especially in Asian countries. On the other hand, the use of minimally invasive techniques is still controversial for the treatment of more advanced tumours, principally due to existing concerns about its oncological adequacy and capacity to carry out an adequately extended lymphadenectomy. Additional high-quality studies comparing laparoscopic gastrectomy versus open gastrectomy for gastric cancer have been recently published, in particular concerning the latest results obtained by laparoscopic approach to advanced gastric cancer. It seems very useful to update the review of literature in light of these new evidences for this subject and draw some considerations.

Abstract
ABSTRACT
Aim: There are very few studies in the literature investigating the changes caused by the Nathanson retractors in liver function tests (LFT) after LG and its clinical significance. The present study investigated the changes made by the Nathanson retractor used during LG on LFT and its clinical significance.
Material and Method: The data of 236 patients, who underwent radical gastrectomy for primary gastric cancer at Surgical Oncology Unit in the period between January 2015 and January 2020 were retrospective studied. The patients were divided into two groups: laparoscopic gastrectomy (LG; 136 cases) and open gastrectomy (OG; 106 cases). Patients who have undergone cholecystectomy, with primary or secondary liver tumors, with chronic hepatic disease, who have preoperative high ALT, AST and bilirubin values were excluded from the study. LFT were measured preoperatively and postoperative day 1 (LFT1), LFT3, LFT5 and LFT7. LFT: ALT, AST and Total bilirubin (BIL).
Results: ALT1, ALT3, ALT5, ALT7 ALT values and AST1, AST3, AST5 AST values of the patients in the LG group were found to be significantly higher (P <0.001). Mean total bilirubin values of the groups were similar (P >0.05). In order to evaluate how the increase in LFT due to the use of the Nathanson retractors reflected on the patients' clinic, we divided the patients who underwent LG into two groups based on ALT increase in ALT1: Normal and Elevated. The in-hospital mortality rates (P = 0.080) and oral nutrition time (P = 0.913) of the groups were similar. No liver infarction developed in any of the groups. The duration of stay in the ICU was significantly longer in individuals with elevated LFT (P = 0.019).
Conclusion: Although the use of the Nathanson retractor during LG causes an increase in liver function tests, this does not cause major clinical problems in patients.

Abstract
PURPOSE This study aimed to investigate the effects of a high body mass index (BMI) on the outcomes of radical gastrectomy for gastric cancer. METHODS We conducted a retrospective cohort study of 1729 patients with stage I to III gastric cancer who received open radical gastrectomy from February 2003 to August 2011. The patients were divided into 3 groups according to their BMI: a low BMI group (BMI < 18.5 kg/m2), normal BMI group (18.5 ≤ BMI < 25 kg/m2), and high BMI group (BMI ≥ 25 kg/m2). RESULTS A total of 871 patients were included in the final analysis, of which the median BMI was 22.7 kg/m2 (range 13.6-44.9 kg/m2). A high BMI increased the risk of postoperative intestinal fistula but not the risk of a reduced number of examined lymph nodes or hospital death. Furthermore, a high BMI did not negatively affect the overall survival (OS) of gastric cancer patients. CONCLUSIONS A high BMI increased the operative morbidity after radical gastrectomy for gastric cancer. However, a high BMI did not negatively affect the quality of lymphadenectomy or the OS of gastric cancer patients in experienced high-volume centers. A careful approach during operation and meticulous perioperative management are required for gastric cancer patients with a high BMI.

Abstract
PURPOSE To compare the short-term surgical outcomes of laparoscopic and open total/proximal gastrectomy using transorally inserted anvil (OrVilTM). METHOD Patients diagnosed with gastric cancer and underwent total or proximal gastrectomy using OrVilTM for reconstruction were included. Clinical and pathological characteristics, as well as postoperative outcomes, were analyzed. Propensity score matching was used to balance baseline factors. RESULTS From April 2012 to April 2020, 199 patients at our center were included. A total of 166 underwent open total or proximal gastrectomy (OTG/OPG), and 33 underwent laparoscopic total or proximal gastrectomy (LTG/LPG). Twenty-seven patients from each group were paired with propensity score matching. The operation time was significantly shorter in the OTG/OPG group after matching. The overall complication rate and the incidence of each complication did not show significant differences between the two groups before and after matching. CONCLUSION LTG/LPG and OTG/OPG using OrVilTM for the alimentary tract reconstruction are both feasible and can achieve similar short-term outcomes.

Since Theodore Billroth and Cesar Roux perfected the methods of post-gastrectomy reconstruction in the late 19th century, surgical management of gastric and gastroesophageal cancer has made incremental progress. The majority of patients with localized disease are treated with perioperative combination chemotherapy or neoadjuvant chemoradiation. Staging laparoscopy before initiation of treatment or before surgical resection has improved staging accuracy and can drastically inform treatment decisions. The longstanding and contentious debate on the optimal extent of lymph node dissection for gastric cancer appears to have settled in favor of D2 dissection with the recently published 15-year follow-up of the Dutch randomized trial. Minimally invasive gastric and gastroesophageal resections are performed routinely in most centers affording faster recovery and equivalent oncologic outcomes. Pylorus-preserving distal (central) gastrectomy has emerged as a less invasive, function-preserving option for T1N0 middle-third gastric cancers, while randomized data on its oncologic adequacy are pending. Multi-visceral resections and cytoreductive surgery with hyperthermic intraperitoneal chemotherapy has been utilized selectively for patients with locally advanced tumors who have demonstrated disease control on preoperative chemotherapy. This review summarizes the current standard of surgical care for gastroesophageal junction and gastric cancer as well as highlights recent and upcoming advances to the field.

Abstract
BACKGROUND In the last decade's robotic gastrectomy (RG) has increasingly widespread as a valid minimally invasive option for treatment of gastric cancer. In literature, evidence of its routine use is not yet well established. The aims of this study are to report our initial experience and to present possible advantages of our hybrid operative technique for subtotal gastrectomy. MATERIALS AND METHODS Retrospectively, we analyzed data from 41 patients (22 male and 19 female) who underwent robot-assisted laparoscopic subtotal gastrectomy (RALG) with D2 lymphadenectomy using the da Vinci XI robotic system. Inclusion criteria were gastric cancer in the middle or lower portion of the stomach amenable of radical subtotal gastrectomy without preoperative suspicion of positive lymph-nodes or other organs involving and distant metastasis. All the procedures were performed by attending surgeons. RESULTS The mean operative time was 270 min with one case of conversion to open surgery. The mean age was 71.4 (IQR 68.2-76.8) with 43.9% of patients classified as ASA (American Society of Anesthesiologists) score ≥3. The median of lymph-nodes retrieved was 25 (IQR 19-35). No intra-operative complications occurred. Time to resume a soft diet was 5 days. Patients were hospitalized a median of 7 days. According to pathological AJCC-TNM, 21 patients were classified as advanced gastric cancer. Post-operative morbidity was recorded in 9 patients (21.9%) with major complications requiring surgical operation in 4 patients (9.8%). Elevated ASA score, fewer lymph-nodes retrieved and ICU recovery requirements were significant increased in patients with major complications. CONCLUSION The preliminary results demonstrated that robot-assisted laparoscopic subtotal gastrectomy is safe and feasible. In particular, we found that the da Vinci platform improves surgeon abilities to perform an adequate lymphadenectomy and digestive reconstruction. Further studies are necessary to better clarify the role of this high-cost technology in minimally invasive treatment of gastric cancer.

Abstract
Introduction: Laparoscopic treatment of gastric cancer in elderly patients is still controversial. The aim of this retrospective study is to evaluate the safety and feasibility of laparoscopic gastrectomy in elderly gastric cancer patients based on the long- and short-term results of laparoscopic surgery. Materials and Methods: The data of 163 patients who underwent laparoscopic gastrectomy for gastric cancer. Patients were categorized into two groups by age based on World Health Organization (WHO) criteria: elderly (≥65 years, 80 cases) and nonelderly (<65 years, 83 cases). Patient characteristics and clinicopathological findings, surgical findings, short- and long-term results were compared between the two groups. Results: The patients in the study group were in the age range of 22-87 years and 80 (49%) patients were found out to be 65 years old or older. When all complications were categorized according to Clavien-Dindo (C-D) classification, >3 serious complication rates were similar between groups (P = .421). Although the length of hospital stay and the need for intensive care were higher in the elderly group, the difference was not significant (P = .066; P = .072). There was no significant difference between the two in terms of in-hospital mortality (P = .364). No statistically significant differences were found in the rates of overall survival (nonelderly group; 61.17 ± 3.34, 95% confidence interval [CI]: 54.61-67.74 versus elderly group; 56.48 ± 3.80, 95% CI: 49.03-63.93; P = .176) and disease-specific survival (nonelderly group; 64.24 ± 3.15, 95% CI: 58.06-70.40 versus elderly group; 61.93 ± 3.57, 95% CI: 54.93-68.93; P = .363) between the age groups. Conclusion: In conclusion, although laparoscopic gastrectomy is a feasible and safe method in elderly gastric cancer patients, further randomized prospective studies are needed.

Abstract
PURPOSE The applicability of laparoscopic-assisted radical gastrectomy for elderly patients with gastric cancer is still not well clarified. The aim of this double-center study was to explore the feasibility and effectiveness of laparoscopic-assisted radical gastrectomy on elderly patients with gastric cancer. METHODS We prospectively collected data of patients who underwent gastrectomy for cancer in two centers from June 2016 to December 2019. Propensity score matching was performed at a ratio of 1:1 to compare the laparoscopic-assisted radical gastrectomy group and open radical gastrectomy group. Univariate analyses and multivariate logistic regression analyses evaluating the risk factors for total, surgical, and medical complications were performed. RESULTS A total of 481 patients with gastric cancer met the inclusion criteria and were included in this study. After propensity score analysis, 258 patients were matched each other (laparoscopic-assisted radical gastrectomy (LAG) group, n = 129; open radical gastrectomy (OG) group, n = 129). LAG group had lower rate of surgical complications (P = 0.009), lower rate of severe complications (P = 0.046), shorter postoperative hospital stay (P = 0.001), and lower readmission rate (P = 0.039). Multivariate analyses revealed that anemia, Charlson comorbidity index, and combined resection were independent risk factors in the LAG group, whereas body mass index and American Society of Anesthesiology grade in the OG group. CONCLUSION Laparoscopic-assisted radical gastrectomy was relative safe even effective in elderly gastric cancer patients. We should pay attention to the different risk factors when performing different surgical procedures for gastric cancer in elderly patients.

Abstract
PURPOSE It remains unclear whether laparoscopic gastrectomy (LG) for gastric cancer is a suitable treatment for very elderly (VE) patients. We aimed to assess the safety and feasibility of LG for gastric cancer in VE patients. METHODS We reviewed 226 consecutive patients who underwent LG between January 2010 and December 2016. We compared VE patients (age ≥ 80, n = 38) with non-elderly patients (age ≤ 79, n = 188). RESULTS An ASA-PS score ≥ 2 was more common in VE group (86.8 vs. 48.9%; P < 0.01). There were no significant differences in the operating time, blood loss, postoperative hospital stay, or postoperative morbidity between the groups. The 3-year survival rate and 3-year disease-specific survival rate were lower in the VE group (53.7 vs. 85.6%; P < 0.0001, 78.5 vs. 92.4%; P = 0.0116). A univariate analysis showed that PS scores ≥ 2, Charlson comorbidity index ≥ 4, and pN stage were independent predictors of decreased overall survival rates in the VE group. A multivariate analysis showed total gastrectomy, a Charlson comorbidity index ≥ 4, and the pN stage to be independent predictors in the VE group. CONCLUSION LG for gastric cancer is, thus, considered to be safe for patients aged 80 years or older. Total gastrectomy, a Charlson comorbidity index ≥ 4, and the pN stage were independent risk factors for a poor prognosis in these patients.

Abstract
BACKGROUND Our study investigated the effect of lymph node (LN) noncompliance on the long-term prognosis of patients after laparoscopic total gastrectomy (LTG) and explored the risk factors of LN noncompliance. METHODS The clinicopathological data of gastric cancer (GC) patients who underwent LTG with D2 lymphadenectomy from June 2007 to December 2013 were prospectively collected and retrospectively analyzed. The effects of LN noncompliance on the long-term prognosis of patients with GC after LTG were explored. RESULTS The overall LN noncompliance rate was 51.9%. The survival rate of patients after LTG with LN compliance was significantly superior to that of patients with LN noncompliance (p = 0.013). The stratified analysis of TNM stage indicated that there was no difference between the OS of stage I patients with LN compliance and those with LN noncompliance; OS of stage II/III patients with LN compliance was significantly better than that of those with LN noncompliance. Cox regression analyses showed that LN noncompliance was an independent risk factor for OS. Logistic regression analysis showed that high BMI (≥ 25 kg/m2) was an independent risk factor for preoperative prediction of LN noncompliance in cStage II/III patients. Patients with a high BMI were more likely to have LN noncompliance during surgery, especially during the dissections of #6, #8a, and #12a LN stations. CONCLUSIONS LN noncompliance was an independent risk factor for poor prognosis in patients with advanced gastric cancer (AGC) after LTG. Patients with high BMI were more likely to have LN noncompliance, especially during the dissections of #6, #8a, and #12a LN stations. LN tracing was recommended for these patients to reduce the rate of LN noncompliance.

Abstract
BACKGROUND The different advantages of laparoscopic gastrectomy (LG) and robotic gastrectomy (RG), two new minimally invasive surgical techniques for gastric cancer, remain controversial. PURPOSE To compare the short-term clinical outcomes of LG and RG. METHODS A retrospective, single-center comparative study of 1044 patients (LG = 750, RG = 294) was conducted. Patients undergoing LG and RG were matched (2:1 ratio) according to sex, age, BMI, extent of gastric resection, and pathologic stage. The primary outcomes were morbidity and mortality and perioperative recovery parameters; major types of complications were also analyzed. RESULTS After matching, 798 patients (LG = 532, RG = 266) were included. Both the LG and RG groups showed similar overall complication rates (LG = 12.8% vs RG = 12.4%) and operative mortality (LG = 0.4% vs RG = 0.4%). Compared to those who underwent LG, patients undergoing RG had significantly longer operative times (236.92 ± 57.28 vs 217.77 ± 65.00 min, p < 0.001), higher total costs (US$16,241.42 vs US$12,497, p < 0.001), less operative blood loss (77.07 ± 64.37 vs 103.68 ± 86.92 ml, p < 0.001), higher numbers of retrieved lymph nodes (32.0 vs 29.9, p < 0.001), and higher rates of retrieving more than 16 lymph nodes (94.0 vs 85.5%; p < 0.001). No significant differences between groups were noted in terms of the rate of reoperation, time until a soft diet was consumed, or length of hospital stay. The major complication and readmission rates were similar in both groups. CONCLUSION RG and LG produced similar short-term clinical outcomes, indicating that RG is a safe and beneficial surgical procedure.

Abstract
BACKGROUND Increasing number of clinical studies have shown that laparoscopic distal gastrectomy (LDG) with D2 lymph node (LN) dissection is an effective method for the treatment of advanced gastric cancer (AGC). However, reports on the technical feasibility and oncology efficacy of laparoscopic total gastrectomy (LTG) in the treatment of AGC are rare. METHODS A retrospective analysis of the clinicopathologic data of 1313 patients with clinical stage of cT2-4aN0-3M0 undergoing laparoscopic radical gastrectomy with D2 LN dissection from June 2007 to December 2013 was performed. Noncompliance was defined as patients with more than one LN station absence as described in the protocol for D2 lymphadenectomy in the Japanese Gastric Cancer Association (JGCA). According to the literature, it was subdivided into LN compliance group (all LN stations were detected), minor LN noncompliance group (1-2 LN stations were not detected), major LN noncompliance group (more than 2 LN stations were not detected). Based on the LN noncompliance, the surgical indications of LTG were analyzed with LDG as control. RESULTS Among the 1313 patients, 197 (39.20%) patients and 321(39.71%) patients in the LDG group and the LTG group had minor LN noncompliance, 59(11.70%) patients and 163(20.10%) patients had major LN noncompliance. The difference in the extent of LN noncompliance between the two groups was statistically significant (p < 0.001). COX proportional hazards regression analysis elucidated that the LN noncompliance was an independent prognostic factor for overall survival (OS). BMI ≥ 25 kg/m2 and the history of previous abdominal surgery (PAS) were independent risk factors for major LN noncompliance in LTG group (p < 0.05), with which patients were defined as a LN noncompliance high-risk group. With the exception of LN noncompliance high-risk group, the difference in the extent of LN noncompliance between LTG group and LDG group was still statistically significant (p = 0.008). Tumor diameter > 60 mm is a preoperative risk factor for station #5 LN noncompliance, and no preoperative risk factors for station #6 LN noncompliance were found, with which patients were defined as LN noncompliance middle-risk group. CONCLUSION LN noncompliance is an independent prognostic factor for poor prognosis in patients after LTG. Based on this finding, patients with BMI ≥ 25 kg/m2, history of PAS and tumor diameter > 60 mm in the advanced stage of upper-middle gastric cancer represent high/middle-risk groups with LN noncompliance in LTG surgery, which should be carefully selected.

Operation time as a simple indicator to predict the overcoming of the learning curve in gastric cancer surgery: a multicenter cohort study. Gastric Cancer 2019; 22:1069-1080. [PMID: 30830639 DOI: 10.1007/s10120-019-00948-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2019] [Accepted: 02/25/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND The aim of this study is to identify an indicator to predict the overcoming of the learning curve of distal gastrectomy in gastric cancer surgery. METHOD A retrospective multicenter cohort study was conducted in 2100 patients who underwent radical distal gastrectomy performed by nine surgeons in eight hospitals between 2001 and 2006. For each surgeon, an individual CUSUM chart was formulated in terms of operation time or clinical outcomes, including severe complications, number of retrieved lymph nodes, positive resection margin, and hospital stay. The actual changing points (CPs) of the CUSUM charts were analyzed. Based on the CP, patients were divided into pre-CP and post-CP groups, and the clinicopathologic outcomes and survival data were compared between the groups. RESULTS CP determined by operation time was more reliable than CP determined by a combination of clinical outcomes, as the former was correlated not only with short-term outcomes but also with survival. The outcomes were superior in the post-CP group in terms of numbers of harvested lymph nodes, sufficient lymph node harvesting (> 15), and negative proximal margins. In a survival analysis, the post-CP group showed better survival than the pre-CP group in stage II (76% vs 86.1% p = 0.010) and stage III (51.5% vs 60.6% p = 0.042). CONCLUSION Overcoming the learning curve of distal gastrectomy for gastric cancer can be better predicted by operation time rather than by a combination of postoperative clinical parameters. It is recommended that surgeons initially operate on early stage cancer patients before overcoming the learning curve.

Abstract
BACKGROUND Laparoscopic distal pancreatectomy (LDP) has gained popularity for the treatment of left-sided pancreatic tumors. Robotic systems represent the most recent advancement in minimally invasive surgical treatment for such tumors. Theoretically, robotic systems are considered to have several advantages over laparoscopic systems. However, there have been few studies comparing both systems in the treatment of distal pancreatectomy. We compared perioperative and oncological outcomes between the two treatment modalities. METHODS A retrospective analysis was conducted of all consecutive minimally invasive distal pancreatectomy cases performed by a single surgeon at a high-volume center between January 2015 and December 2017. RESULTS The analysis included 228 consecutive patients (LDP, n = 182; Robotic-assisted laparoscopic distal pancreatectomy [R-LDP], n = 46). Operative time was significantly longer in the R-LDP group than in the LDP group (166.4 vs. 140.7 min; p = 0.001). In a subgroup analysis of patients who underwent the spleen-preserving approach, the spleen preservation rate associated with R-LDP was significantly higher than that associated with LDP (96.8% vs. 82.5%; p = 0.02). In another subgroup analysis of patients with pancreatic cancer, there were no significant differences in median overall and disease-free survival between the two groups. CONCLUSIONS R-LDP is a safe and feasible approach with perioperative and oncological outcomes comparable to those of LDP. R-LDP offers an added technical advantage that enables the surgeon to perform a complex procedure with good ergonomic comfort.

Abstract
BACKGROUND In the last decade the implementation of the new technique of endoscopic submucosal dissection (ESD) and the rapid progression of laparoscopic gastric cancer (LAG) resection with an adequate lymphadenectomy (LAD) have played an increasing role in the treatment of patients with early stage gastric cancer (EGC). OBJECTIVE A systematic review of the currently available data in the literature was carried out to evaluate the contemporary surgical management for treatment of EGC. RESULTS Endoscopic resection (ER) of mucosal T1 gastric cancer (T1m) in accordance with the German guidelines on resection criteria is a widely accepted treatment option, if a definitive R0 resection can be achieved. Excellent en bloc and R0 results in more than 90% of these cases have been shown particularly for ESD. In contrast to T1m gastric carcinomas with a low risk of lymph node metastases (approximately 3%), nodal involvement reaches more than 20% for submucosal infiltrated EGC (T1sm). For this reason, a surgical resection with adequate LAD is further recommended in all cases of non-curative ER or any T1sm gastric cancer. In seven randomized controlled trials and a series of meta-analyses including high-quality non-randomized trials, significant benefits in short-term postoperative outcome have been demonstrated for LAG in comparison to open gastrectomy (OG) in the treatment of EGC. The general morbidity was also significantly lower in LAG than in OG. The 30-day mortality and long-term survival outcome were comparable between the two groups. CONCLUSION The use of ESD should be the standard treatment for T1m EGC within the guidelines criteria. For non-curative ESD and T1sm gastric cancer, surgical resection with LAD is recommended. The LAG is a technically safe, feasible, and favorable approach in terms of faster recovery compared to OG. The long-term survival outcome is comparable between LAG and OG for EGC.

Abstract
The gravest prognostic factor in early gastric cancer is lymph-node metastasis, with an incidence of about 10% overall. About two-thirds of early gastric cancer patients can be diagnosed as node-negative prior to treatment based on clinic-pathological data. Thus, the tumor can be resected by endoscopic submucosal dissection. In the remaining third, surgical resection is necessary because of the possibility of nodal metastasis. Nevertheless, almost all patients can be cured by gastrectomy with D1+ lymph-node dissection. Laparoscopic or robotic gastrectomy has become widespread in East Asia because perioperative and oncological safety are similar to open surgery. However, after D1+ gastrectomy, functional symptoms may still result. Physicians must strive to minimize post-gastrectomy symptoms and optimize long-term quality of life after this operation. Depending on the location and size of the primary lesion, preservation of the pylorus or cardia should be considered. In addition, the extent of lymph-node dissection can be individualized, and significant gastric-volume preservation can be achieved if sentinel node biopsy is used to distinguish node-negative patients. Though the surgical treatment for early gastric cancer may be less radical than in the past, the operative method itself seems to be still in transition.

Abstract
Objective: Lymph node metastasis (LNM) is one of the important prognostic factors of early gastric cancer (EGC). Moreover, LNM is also important when choosing therapeutic intervention for EGC patients. The purpose of this study is to explore the risk factors of LNM in EGC and to discuss the corresponding treatment. Design: We retrospectively reviewed the medical records of 253 patients with EGC who underwent surgical therapy in our department between 2012 and 2015. Univariate analysis and Multivariate Cox regression were used to evaluate the independent risk factors of LNM. Results: LNM was present in 38 cases among 253 patients (15%). Univariate analysis showed an obvious correlation between LNM and tumour location, tumour size, depth of invasion, morphological classification, gross type of the lesion and venous invasion. Multivariate analysis indicated that poorly differentiated carcinoma, submucosal cancer, tumour size ≥2 cm and venous invasion were the independent risk factors for LNM. Conclusion: Tumour size, depth of invasion, morphological classification and blood vessel invasion were predictive risk factors for LNM in EGC. We propose that EGC patients with those risk factors should be accepted gastrectomy with LN dissection.

Abstract
Adhesion formation that occurred after alkali-induced injury of the cecum was used as a novel adhesion model in rats, and it was compared with that of a common adhesion model after abrading the cecum. Using the novel adhesion model, inhibition of adhesion formation by a chymase inhibitor, Suc-Val-Pro-PheP(OPh)2, and by sodium hyaluronate/carboxymethylcellulose (Seprafilm) was evaluated, and their mechanisms were assessed. The degree of adhesion formation was more severe and more stable in the alkali-induced injury model than in the abrasion-induced injury model. Both the chymase inhibitor and Seprafilm showed significant attenuation of the degree of adhesion 14 days after alkali-induced injury. Chymase activity in the cecum was significantly increased after alkali-induced injury, but it was significantly attenuated by the chymase inhibitor and Seprafilm. Myeloperoxidase and transforming-growth factor (TGF)-β levels were significantly increased after alkali-induced injury, but they were attenuated by both the chymase inhibitor and Seprafilm. At the level of the adhesions, the numbers of both chymase-positive cells and TGF-β-positive cells were significantly increased, but their numbers were reduced by the chymase inhibitor and Seprafilm. In conclusion, a chymase inhibitor attenuated the degree of adhesions to the same degree as Seprafilm in a novel peritoneal adhesion model that was more severe and more stable than the common adhesion model, and not only the chymase inhibitor, but also Seprafilm reduced the chymase increase at the adhesions.

Abstract
Laparoscopic surgery for remnant gastric cancer has been reported in a limited number of cases, and data on post-operative complications are lacking. A 58-year-old male was admitted with remnant gastric cancer. He had undergone open subtotal gastrectomy 9 years ago for gastric cancer. Laparoscopic total gastrectomy was performed, and he was discharged on the 10th day uneventfully. The patient had complained of nausea and vomiting in the 2nd post-operative month. He clinically and radiologically diagnosed as ileus and required open emergency surgery. There was a transverse colon stenosis near the splenic flexure. Hartmann's procedure was done, and he was discharged on day 17. We have limited knowledge about colonic complications after laparoscopic gastric surgery. The development of stenosis in the transverse colon is one of these complications that should be kept in mind. As far as we know, such a complication has never been reported before.

Abstract
In this article, the current state of laparoscopic total gastrectomy (LTG) was reviewed, focusing on lymph node dissection and reconstruction. Lymph node dissection in LTG is technically similar to that in laparoscopic distal gastrectomy for early gastric cancer; however, LTG for advanced gastric cancer requires extended lymph node dissections including splenic hilar lymph nodes. Although a recent randomized controlled trial clearly indicated no survival benefit in prophylactic splenectomy for lymph node dissection at the splenic hilum, some patients may receive prognostic benefit from adequate splenic hilar lymph node dissection. Considering reconstruction, there are two major esophagojejunostomy (EJS) techniques, using a circular stapler (CS) or using a linear stapler (LS). A few studies have shown that the LS method has fewer complications; however, almost all studies have reported that morbidity (such as anastomotic leakage and stricture) is not significantly different for the two methods. As for CS, we grouped various studies addressing complications in LTG into categories according to the insertion procedure of the anvil and the insertion site in the abdominal wall for the CS. We compared the rate of complications, particularly for leakage and stricture. The rate of anastomotic leakage and stricture was the lowest when inserting the CS from the upper left abdomen and was significantly the highest when inserting the CS from the midline umbilical. Scrupulous attention to EJS techniques is required by surgeons with a clear understanding of the advantages and disadvantages of each anastomotic device and approach.

Abstract
Objective To investigate the prognostic impact of postoperative complications for patients with gastric cancer. Methods Postoperative complications of patients undergoing radical gastrectomy for gastric cancer were reviewed. The severity of complications was graded by the CCI and C-D classification. Results A total of 5327 patients were included in the study. Complications were observed in 767 patients. When the C-D classification system was applied, for patients with grade I-II complications, the length of stay (LOS) of those with high CCI (CCI ≥ 26.2) was significantly longer than that of patients with low CCI (CCI < 26.2) (p < 0.001). The 5-year cancer-specific survival rate of patients with complications (52%) was lower than that of patients without complications (61%) (p < 0.001). Analysis of the factors associated with prognosis in patients with gastric cancer revealed that complications were independent risk factors for specific survival. When CCI was used to classify complication severity, the 5-year cancer-specific survival rate of the high-CCI group was 46.3%, which was lower than that of the low-CCI group (54.9%, p = 0.009). Conclusion Complication after radical gastrectomy is an independent prognostic factor, and the complication severity as graded by CCI reflects the difference of cancer-specific survival in gastric cancer patients with postoperative complications.

BACKGROUND The adequacy of laparoscopy-assisted gastrectomy (LAG) for advanced gastric cancer (AGC) treatment remains uncertain. There are few reports on the long-term outcomes of laparoscopic versus open gastrectomy (OG) in AGC using subgroups with adequate patient numbers; which may provide further evidence to validate the long-term efficacy of LAG in AGC. METHODS A retrospective cohort study included 1198 consecutive AGC patients underwent LAG or OG between September 2005 and October 2012 was conducted to compare the long-term outcomes. RESULTS Of the 1198 patients, 430 (35.9%) underwent LAG, and 768 (64.1%) underwent OG. Recurrences occurred in 203 patients (47.2%) in LAG group and in 387 patients (50.4%) in the OG group (P = 0.091). Five-year overall survival and disease-free survival rates of the two groups were similar, which is 51.2% vs. 46.7%, (P = 0.081) and 52.8% vs. 49.6%, (P = 0.091). The surgical approach (LAG or OG) did not influence the disease-free survival (HR 0.975, 95% CI 0.712 to 1.336; P = 0.875). CONCLUSIONS This study suggests that LAG with D2 lymphadenectomy may be a feasible and safe procedure for AGC treatment.

Abstract
BACKGROUND It is still unclear whether enhanced recovery after surgery is effective and safe in laparoscopic gastrectomy for gastric carcinoma. METHODS Cochrane library databases, Medline, Embase, and Pubmed were searched from January 1, 1986, to December 31, 2016. Randomized controlled trials (RCTs) comparing fast-track recovery with conventional recovery strategies in laparoscopic radical gastrectomy for gastric carcinoma were included. The main outcomes measured were postoperative hospital stay, time to first flatus, hospital charge, and overall complication rate. RESULTS Six RCTs with 400 patients were included in this study. Fast-track surgery has shorter postoperative hospital stays (weighted mean difference (WMD) - 2.65; 95% CI, - 4.01 to - 1.29, z = 3.82, P < 0.01) and less hospitalization expenditure (WMD - 523.43; 95% CI, - 799.79 to - 247.06, z = 3.71, P < 0.01) than conventional recovery strategies. There was no significant difference with respect to duration to first flatus (WMD - 17.72; 95% CI, - 39.46-4.02, z = 1.60, P = 0.11) and complication rate (OR 1.57; 95% CI, 0.82-2.98, z = 1.37, P = 0.17). CONCLUSIONS Enhanced recovery after surgery is effective and safe and is thus recommended in laparoscopic radical gastrectomy for gastric carcinoma.

Abstract
INTRODUCTION Curative laparoscopic gastrectomy (LG) is associated with good outcomes when performed for early gastric cancers. The aim of this study was to identify risk factors for recurrence after LG. METHODS 212 patients with gastric cancer who underwent gastrectomy were enrolled (LG: 143, open gastrectomy, OG: 69). Univariate analysis was used to assess overall (OS) and disease-free survival (DFS) in LG and OG group. Multivariate analysis was used to assess risk factors for recurrence after LG. RESULTS In LG, six cases of recurrence were observed (liver: 2, peritoneum: 4). Neither lymph node nor port-site recurrences were evident after LG. The 5-year DFS after LG was 91.4%. Based on univariate analysis of 5-year DFS, three negative prognostic factors-lymph node metastasis, lymphatic invasion, and venous invasion-were identified. The independent risk factor for recurrence of LG was lymph node metastasis. LG and OG showed no significant differences in 5-year DFS among Stage IA, IB, IIA, and IIB groups. Independent risk factors for recurrence after LG or OG were tumor invasion≥muscularis mucosa and lymph node metastasis. CONCLUSIONS DFS following LG is comparable to that following OG. Lymph node metastasis is an independent risk factor for gastric cancer recurrence after LG. J. Med. Invest. 64: 79-84, February, 2017.

Abstract
OPINION STATEMENT The management of cervical lymph node metastasis remains a crucial component of the treatment of head and neck cancers. However, the proper management of clinical N 0 cases with early-stage oral squamous cell carcinoma (OSCC) remains undefined. In the advent of minimally invasive techniques in the 1980s, these techniques have gained popularity among numerous surgeons in all fields of surgery. Although there are no randomized controlled trial data comparing the outcomes of minimally invasive techniques (endoscopically assisted selective neck dissection (SND), robot-assisted SND) with conventional techniques, encouraging evidence from several studies suggests that both endoscopically assisted SND and robot-assisted SND are safe, minimally invasive techniques with achieved short-term oncologic outcomes and can reach a better cosmetic outcome than conventional SND. In this review, we also compare the indications, surgical approaches, and relative advantages and disadvantages of conventional SND, endoscopically assisted SND, and robot-assisted SND to provide surgeons with a means to better consider these techniques for the treatment of early-stage OSCC.

Abstract
Laparoscopic gastrectomy is evolving. With the increasing expertise and experience of oncologic surgeons in the minimally invasive surgery for gastric cancer, the indication for laparoscopic gastrectomy is expanding to advanced cases. Many studies have demonstrated the benefits of minimally invasive surgery, including reduced risk of surgery-related injury, reduced blood loss, less pain, and earlier recovery. In order to establish concrete evidence for the suitability of minimal invasive surgery for gastric cancer, many multicenter RCTs, comparing the short- and long-term outcomes of laparoscopic versus open surgery, are in progress. Advances in laparoscopic gastrectomy are moving toward increasingly minimally invasive approaches that enable the improvement of the quality of life of patients, without compromising on oncologic safety.

Abstract
OBJECTIVE To introduce a novel laparoscopic training system with a continuously perfused ex-vivo porcine liver for hepatobiliary surgery. BACKGROUND Existing models for laparoscopic training, such as box trainers and virtual reality simulators, often fail to provide holistic training and real haptic feedback. We have formulated a new training system that addresses these problems. METHODS Real-Liver Laptrainer consists of a porcine liver, customized mannequin, ex-vivo machine perfusion system, and monitoring software. We made a detailed comparison of Real-Liver Laptrainer with the LapSim virtual reality simulator and the FLS Trainer Box systems. Five laparoscopic surgeons assessed the new system on multiple features. We assessed the performances of 43 trainees who used the new system to perform laparoscopic cholecystectomy (LC) three times. RESULTS Real-Liver Laptrainer offered more functions and better tactile feedback than the FLS or LapSim system. All five surgeons graded the quality of the new system as realistic. The utility of the system for training was scored as 3.6 ± 1.1 on a scale of 1-5. Between the first and third attempts, the number of successfully performed LCs increased (9 vs 14 vs 23; P = .011), while the numbers of liver damage incidents (25 vs. 21 vs. 18, P = .303) and gallbladder perforations decreased (17 vs. 12 vs. 9, P = .163). The mean LC operation time significantly decreased (63 vs. 50 vs. 44, P < .0001). CONCLUSION Real-Liver Laptrainer is a feasible, stable, and practical training model that has potential for improving the laparoscopic skills of surgeons.

Abstract
The aim of this study was to compare the outcomes of laparoscopic surgery (LAP) and open gastric surgery (OP) in early gastric cancer patients aged ≥70 years.We conducted a retrospectively analysis among patientswith pathological T1N0M0 gastric cancer,who underwent LAP or OP between January 1, 2001 and December 31, 2008. We identified a well-balanced cohort of 2,360 patients (1180 patients in each group). LAP has been shown to offer a superior perioperative results to OP, including lower blood loss, shorter time to oral intake, walk and bowel function recovery, shorter time of hospital stay, and less blood transfusion required. However, the intraoperative and postoperative complications, local recurrence, and metastasis didn't show statistically significant differences between groups. The 5-year overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS) were 60.1% vs.63.2%, 80.8% vs. 83.3%, and 87.6% vs. 89.5% in the LAP group and OP group, respectively. The hazard ratios (HR) for OS, DFS, and CSS were 1.09(95% confidence interval [CI]: 0.95-1.25; P = 0.215), 1.03(95% CI: 0.91-1.18; P = 0.636), and 1.07 (95% CI: 0.88-1.30; P = 0.484), respectively, compared LAP group with OP group. In conclusion, LAP is an acceptable alternative to OP in elderly patients with early gastric cancer.

Abstract
Background and Purpose: Validation of laparoscopic total gastrectomy (LTG) for patients with gastric cancer has not been fully investigated. In particular, the technique for esophagojejunostomy remains controversial. We performed 103 cases of LTG for patients with gastric cancer between 2007 and 2013, in which all esophagojejunostomy reconstruction was performed with intracorporeal circular stapling esophagojejunostomy using the OrVil system except for the first 3 cases. The purpose of this study is to retrospectively analyze the clinical usefulness of LTG with intracorporeal circular stapling esophagojejunostomy using the OrVil system and oncological feasibility of LTG as compared with open total gastrectomy (OTG). Patients and Method: We retrospectively analyzed clinical course of consecutive 100 operations with LTG in comparison with consecutive 53 operations with OTG for patients with gastric cancer. As an estimation of short-term outcome, operative time, blood loss, postoperative hospital days and postoperative data of blood and drain examination were included. Moreover, relapse-free survival time and overall survival time stratified by each stage were calculated by log-rank test as an estimation of prognostic relevance. Results: Blood loss and postoperative hospital stay of LTG were significantly less than that of OTG. Postoperative complications were equivalent between the 2 groups and no patient died within 1 month post-LTG. Only 1 patient had recurrence and died for carcinomatosa peritonitis 50 months after LTG (median follow-up period: 44 mo). Conclusions: Our experience revealed that LTG with intracorporeal circular stapling esophagojejunostomy using the OrVil system could be performed safely and with acceptable oncological outcome for patients with gastric cancer.

Abstract
BACKGROUND To evaluate feasibility and benefits of intracorporeal anastomosis, we compared short-term surgical outcomes between laparoscopy-assisted distal gastrectomy (LADG) and totally laparoscopic distal gastrectomy (TLDG) with Billroth-II (B-II) anastomosis for gastric cancer. METHODS Sixty patients underwent attempted B-II TLDG from 2011 through 2013. Patients who underwent B-II LADG prior to 2011 were matched to TLDG cases for demographics, comorbidities, tumor characteristics, and TNM stage. Perioperative and short-term surgical outcomes were compared between the two groups. RESULTS Clinicopathological characteristics of both groups were comparable. The B-II TLDG group had a shorter hospital stay (9.4 vs. 12.0 days, P = 0.038) and average incision size was smaller (3.5 vs. 5.4 cm, P = 0.030) than in the B-II LADG group. Anastomotic leakage was not recorded in either group, and there were no differences in the rates of perioperative complications and in inflammatory parameters between the two groups. CONCLUSIONS This study suggests that B-II TLDG is feasible, compared to B-II LADG, and that it has several advantages over LADG, including a smaller incision, a shorter hospital stay, and more convenience during surgery. However, prospective randomized controlled studies are still needed to confirm that B-II TLDG can be used as a standard procedure for LDG.

BACKGROUND AND AIMS Although endoscopic submucosal dissection (ESD) for expanded-indication lesions of differentiated-type early gastric cancer (EGC) has been widely accepted, no prospective randomized study has been conducted on this subject. This study aimed to evaluate the long-term outcomes of ESD and surgery for expanded-indication lesions of differentiated-type EGC. METHODS Between 1997 and 2012, 1500 consecutive patients with EGC were treated in Osaka City University Hospital. Using propensity score matching and inverse probability of treatment weighting (IPTW), we retrospectively evaluated the long-term outcomes, risk factors for mortality, and adverse events for patients with expanded-indication lesions of differentiated-type EGC who underwent ESD or surgical treatments. RESULTS A total of 308 patients with expanded-indication lesions of differentiated-type EGC confirmed by pathologic examination after ESD or surgery met the eligibility criteria. After matching, the 5-year overall survival rate was higher in the ESD group than in the surgery group (97.1% vs 85.8%; P = .01). We also found that surgery was significantly associated with mortality using both the IPTW method (hazard ratio [HR], 10.89; 95% confidence interval [CI], 1.37-86.6; P < .01), and Cox analysis (HR, 8.60; 95% CI, 1.11-66.52; P = .04) after matching. Significantly fewer adverse events were associated with ESD than with surgery (6.8% vs 28.4%; P < .01). No cause-specific mortality was observed in either group. CONCLUSIONS Our results indicate that ESD might be an alternative treatment modality for expanded-indication lesions of differentiated-type EGC.

Applicability of endoscopic submucosal dissection for undifferentiated early gastric cancer: Mixed histology of poorly differentiated adenocarcinoma and signet ring cell carcinoma is a worse predictive factor of nodal metastasis. Surg Oncol 2016; 26:8-12. [PMID: 28317588 DOI: 10.1016/j.suronc.2016.12.001] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2016] [Revised: 10/20/2016] [Accepted: 12/06/2016] [Indexed: 12/16/2022]
Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is not considered an appropriate treatment for undifferentiated early gastric cancer (UEGC) due to the higher risk of nodal metastases. We aimed to investigate predictive factors for nodal metastases in UEGCs, determine whether the tumor histology is an independent factor for it, and explore whether ESD is applicable for UEGC. METHODS We reviewed the medical records of 1837 patients who underwent curative gastrectomy for poorly differentiated adenocarcinoma, signet ring cell carcinoma, and a mixed type of both tumors between 2008 and 2012. RESULTS Nodal metastases were found in 208 (11.3%) patients. Multivariate analysis revealed that lymphovascular invasion and tumor histology were significantly associated with nodal metastases in mucosal cancers, the rates of which were higher in mixed type tumors (6.3%) than in the other two types (2.0-2.5%; p = 0.005). No nodal metastases were observed in poorly differentiated adenocarcinomas <2 cm and signet ring cell carcinomas <1 cm without lymphovascular invasion and confined to the mucosa. CONCLUSION Mixed type tumors should not be considered for endoscopic resection. ESD might be applicable for mucosal tumors with poorly differentiated adenocarcinoma <2 cm and signet ring cell carcinoma <1 cm without lymphovascular invasion.

Abstract
BACKGROUND To investigate the incidence of and factors associated with postoperative complications and failure to rescue following laparoscopic and open gastrectomy for gastric cancer. STUDY DESIGN We analyzed the records of 4124 patients who underwent a laparoscopic or open gastrectomy for gastric cancer. One-to-one propensity score matching was performed to compare the difference between the two groups. RESULTS A total of 4124 patients were included in the study, 627 of whom (15.2 %) developed postoperative complications. Postoperative deaths occurred in 23 (0.6 %) patients with serious complications. In the propensity score matching analysis with 1361 pairs, no significant differences in the rates of overall complications (14.2 vs. 16.5 %, p = 0.093) were observed between laparoscopic and open gastrectomy group. In-hospital mortality decreased in patients who underwent laparoscopic gastrectomy compared to patients who underwent open gastrectomy (0.3 vs. 1.2 %, p = 0.004). Failure to rescue rates were lower in patients who underwent laparoscopic gastrectomy (2.1 vs. 7.6 %, p = 0.008). Multivariate analysis showed that older age, tumor location, TNM stage classification, extent of gastric resection, operative time and intra-operative blood loss were adverse risk factors for postoperative complications. Laparoscopic gastrectomy was found to be a protective factor for failure to rescue. Complications associated with failure to rescue included abdominal bleeding, anastomotic leakage and cardiac events. In-hospital mortality increased as the number of complications per patient increased. CONCLUSIONS Assuming equal competence with open and laparoscopic approaches of a surgeon, the proportion of patients with postoperative complications were similar among those who underwent laparoscopic gastrectomy compared to patients who underwent open gastrectomy. However, when complications occurred, patients with open gastrectomy were more likely to die.

Abstract
The risk factors associated with postoperative pulmonary complications (PPCs) following laparoscopic gastrectomy have not been well studied. We sought to identify the risk factors for PPCs following gastric cancer surgery.A retrospective analysis was performed on all gastric cancer patients in a prospective database who underwent a laparoscopic gastrectomy from 2004 to 2014. The potential risk factors for PPCs were evaluated.PPCs occurred in 6.8% (83/1205) of patients and included pneumonia in 56 (67.5%) patients, pleural effusion in 26 (31.3%) patients, and pulmonary embolism in 1 (1.2%) patient. The multivariate analysis identified the following significant risk factors for PPCs: advanced age (odds ratio [OR] = 1.043, 95% confidence interval [CI] = 1.021%, 1.066%), chronic obstructive pulmonary disease (COPD) (OR = 17.788, 95% CI = 2.618%, 120.838%), total gastrectomy (OR = 2.781, 95% CI = 1.726%, 4.480%), time to first diet (OR = 1.175, 95% CI = 1.060%, 1.302%), and postoperative hospital stay (OR = 1.015, 95% CI = 1.002%, 1.028%). The risk factors for pneumonia included advanced age (OR = 1.036, 95% CI = 1.010%, 1.063%), total gastrectomy (OR = 3.420, 95% CI = 1.960%, 5.969%), and time to first diet (OR = 1.207, 95% CI = 1.703%, 1.358%). Only pancreatectomy was a risk factor for pleural effusion (OR = 9.082, 95% CI = 2.412%, 34.206%).The frequency of PPCs in patients with gastric cancer who underwent laparoscopic surgery was relatively high. Patients with cardiac and pulmonary comorbidities and those who undergo total gastrectomy and combined resection should be considered at high risk.

Abstract
Radical gastrectomy with an adequate lymphadenectomy is the main procedure which makes it possible to cure patients with resectable gastric cancer (GC). A number of randomized controlled trials and meta-analysis provide phase III evidence that laparoscopic gastrectomy is technically safe and that it yields better short-term outcomes than conventional open gastrectomy for early-stage GC. While laparoscopic gastrectomy has become standard therapy for early-stage GC, especially in Asian countries such as Japan and South Korea, the use of minimally invasive techniques is still controversial for the treatment of more advanced tumours, principally due to existing concerns about its oncological adequacy and capacity to carry out an adequately extended lymphadenectomy. Some intrinsic drawbacks of the conventional laparoscopic technique have prevented the worldwide spread of laparoscopic gastrectomy for cancer and, despite technological advances in recent year, it remains a technically challenging procedure. The introduction of robotic surgery over the last ten years has implied a notable mutation of certain minimally invasive procedures, making it possible to overcome some limitations of the traditional laparoscopic technique. Robot-assisted gastric resection with D2 lymph node dissection has been shown to be safe and feasible in prospective and retrospective studies. However, to date there are no high quality comparative studies investigating the advantages of a robotic approach to GC over traditional laparoscopic and open gastrectomy. On the basis of the literature review here presented, robot-assisted surgery seems to fulfill oncologic criteria for D2 dissection and has a comparable oncologic outcome to traditional laparoscopic and open procedure. Robot-assisted gastrectomy was associated with the trend toward a shorter hospital stay with a comparable morbidity of conventional laparoscopic and open gastrectomy, but randomized clinical trials and longer follow-ups are needed to evaluate the possible influence of robot gastrectomy on GC patient survival.

Abstract
BACKGROUND The aim of this study was to identify factors associated with perioperative morbidity among patients who underwent laparoscopic gastrectomy while receiving antithrombotic therapy (ATT). PATIENTS AND METHOD This retrospective cohort study included 46 patients (14 females and 32 males) who underwent laparoscopic gastrectomy, including 12 (26.1 %) who received perioperative ATT, between January 2012 and November 2015 in our institution. Among patients receiving only aspirin as antiplatelet therapy, none were on anticoagulation therapy. All patients took aspirin as antiplatelet therapy for cardiac indications. The clinical findings and surgical outcomes of patients who did (ATT group) and did not (control group) receive ATT were compared. RESULTS The intraoperative mortality was 0 % for both groups. There was no significant difference in the incidence of postoperative morbidity by univariate analysis between the control and ATT groups (8.8 vs. 8.3 %, p = 0.39). CONCLUSION The risk of postoperative morbidity of laparoscopic gastrectomy can be equivalent between the ATT and non-ATT (control) groups.
