Abstract
PURPOSE Minimally-invasive total gastrectomy (MITG) is associated with lower morbidity in comparison to open total gastrectomy but requires a learning curve (LC). We aimed to perform a pooled analysis of the number of cases required to surmount the LC (NLC) in MITG. METHODS A systematic review of PubMed, Embase, Scopus and the Cochrane Library from inception until August 2022 was performed for studies reporting the LC in laparoscopic total gastrectomy (LTG) and/or robotic total gastrectomy (RTG). Poisson mean (95% confidence interval [CI]) was used to determine the NLC. Negative binomial regression was performed as a comparative analysis. RESULTS There were 12 articles with 18 data sets: 12 data sets (n = 1202 patients) on LTG and 6 data sets (n = 318 patients) on RTG. The majority of studies were conducted in East Asia (94.4%). The majority of the data sets (n = 12/18, 66.7%) used non-arbitrary analyses. The NLC was significantly smaller in RTG in comparison to LTG [RTG 20.5 (95% CI 17.0-24.5); LTG 43.9 (95% CI 40.2-47.8); incidence rate ratio 0.47, p < 0.001]. The NLC was comparable between totally-laparoscopic total gastrectomy (TLTG) and laparoscopic-assisted total gastrectomy (LATG) [LATG 39.0 (95% CI 30.8-48.7); TLTG 36.0 (95% CI 30.4-42.4)]. CONCLUSIONS The LC for RTG was significantly shorter for LTG. However existing studies are heterogeneous.

Abstract
BACKGROUND Minimally invasive distal gastrectomy (MIDG) is non-inferior compared with open distal gastrectomy for gastric cancer. However, MIDG bears a learning curve (LC). This study aims to evaluate the number of cases required to surmount the LC (i.e. NLC) in MIDG. METHODS PubMed, Embase, Scopus, and the Cochrane Library were systematically searched from inception to August 2022 for studies which reported NLC in MIDG. NLC on reduced-port/single-port MIDG only were separately analysed. Poisson mean (95% confidence interval (CI)) was used to determine NLC. Negative binomial regression was used to compare NLC between laparoscopic distal gastrectomy (LDG) and robotic distal gastrectomy (RDG). RESULTS A total of 45 articles with 71 data sets (LDG n=47, RDG n=24) were analysed. There were 7776 patients in total (LDG n=5516, RDG n=2260). Majority of studies were conducted in East Asia (n=68/71). Majority (76.1%) of data sets used non-arbitrary methods of analyses. The overall NLC for RDG was significantly lower compared to LDG (RDG 22.4 (95% CI: 20.4-24.5); LDG 46.7 (95% CI: 44.1-49.4); incidence rate ratio 0.48, p<0.001). The median number of laparoscopic gastrectomy (LG) cases prior was 0 (interquartile range (IQR) 0-105) for LDG and 159 (IQR 101-305.3) for RDG. Meta-regression analysis did not show a significant impact prior experience in LG, extent of lymphadenectomy and intracorporeal vs extracorporeal anastomosis had on overall NLC for LDG and RDG. CONCLUSION NLC for RDG is shorter compared to LDG, but this may be due to prior experience in LG and ergonomic advantages of RDG.

[PMID: 37923841 PMCID: PMC10624863 DOI: 10.1038/s41598-023-46246-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 10/30/2023] [Indexed: 11/06/2023] Open
Abstract
The safety of laparoscopic gastrectomy compared with that of open surgery for the treatment of early gastric cancer (EGC) is unidentified on a national scale. We aimed to compare the morbidity between laparoscopic and open gastrectomies for pathological T1 gastric cancer based on nationwide survey data. Data of 14,076 patients who underwent gastric cancer surgery obtained from the 2019 Korean Gastric Cancer Association-led nationwide survey were used. For patients with pathological T1 gastric cancer, the clinical characteristics were compared between the laparoscopic and open gastrectomy groups. Propensity score matching (PSM) was performed to match the baseline characteristics of the groups. Among the 7765 patients with pathological T1 gastric cancer who underwent open or laparoscopic gastrectomy, 612 pairs were matched. After balancing the baseline characteristics, the laparoscopic gastrectomy group had a significantly longer operative time, less blood loss, greater number of harvested lymph nodes, shorter hospital stays, and comparable morbidity, compared with the open gastrectomy group (P < 0.001, P < 0.001, P < 0.001, P = 0.001, and P = 0.709, respectively). The surgical approach was not a risk factor for postoperative complication in logistic regression analysis. The PSM analysis with the 2019 Korean nationwide survey data demonstrated that laparoscopic gastrectomy showed comparable morbidity with open gastrectomy for EGC.

The Learning Curve for Hand-Assisted Laparoscopic Total Gastrectomy in Gastric Cancer Patients. J Clin Med 2022; 11:jcm11226841. [PMID: 36431318 PMCID: PMC9698309 DOI: 10.3390/jcm11226841] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 11/11/2022] [Accepted: 11/12/2022] [Indexed: 11/22/2022] Open
Abstract
(1) Background: Hand-assisted laparoscopic total gastrectomy (LTG) for patients with gastric cancer (GC) has been established as the standard surgical treatment at our center. This study aims to quantify the learning curve for surgeons performing minimally invasive total gastrectomy at a high-volume single center. (2) Methods: One hundred and eighteen consecutive patients who underwent minimally invasive total gastrectomy between January 2014 and December 2020 at a single high-volume center were included and reviewed retrospectively. Risk-adjusted cumulative sum analysis (RA-CUSUM) was used to monitor the surgical outcomes for patients with different risks of postoperative mortality using varying-coefficient logistic regression models. Patients were ordered by the sequential number of the procedure performed and divided into two groups according to the degree of surgeon proficiency as determined by RA-CUSUM analysis (group A: 45; group B: 73 patients). Age, gender, body mass index (BMI), tumor location, pathology, and comorbidities were compared while primary endpoints comprised surgical parameters, postoperative course, and survival outcomes. (3) Results: Forty-four cases were required for the completion of the learning curve. During this time, the mean operating time decreased. Hand-assisted laparoscopic total gastrectomy performed after a learning curve was associated with a shorter median operating time (OT) (360 min vs. 289 min, <0.001), and a reduced length of stay (A = 18.0 vs. B = 14.0 days) (p = 0.154), while there was a trend toward less major complications (Clavien−Dindo (CD) 3−5 within 90 days (12 (26.67%) vs. 10 (13.70%) p = 0.079). Our results showed no difference in anastomotic leakage between the two groups (group A vs. group B, 3 (6.67%) vs. 4 (5.48%) p = 0.99). Similarly, 30-day (0 (0%) vs. 1 (1.7%), p = 0.365) and 90-day mortality (1 (2.08%) vs. 2 (3.39%), p = 0.684) were comparable. Following multivariate analysis, the level of surgical proficiency was not a significant prognostic factor for overall survival. (4) Conclusions: A minimum of 44 cases are required for experienced laparoscopic surgeons to achieve technical competence for performing LTG. While operation time decreased after completion of the learning curve, quality criteria such as achievement of R0 resection, anastomotic leakage, and perioperative mortality remained unaltered. Of note, the level of surgical training showed no significant impact on the 2 year OS or DFS.

A national advanced training program for laparoscopic radical gastrectomy has a positive impact on surgical trainees: A before and after study (ATP-LRG-1). Int J Surg 2022; 104:106781. [PMID: 35963576 DOI: 10.1016/j.ijsu.2022.106781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 07/01/2022] [Accepted: 07/07/2022] [Indexed: 10/15/2022]
Abstract
BACKGROUND Due to the high technical requirements of laparoscopic radical gastrectomy (LRG), establishing an effective training system to promote clinical technology and operation specifications is necessary. We aimed to evaluate the effect of a national advanced training program for LRG (ATP-LRG). MATERIALS AND METHODS The contents of the training include the following: 1) detailed technique descriptions; 2) prevention and solving of intraoperative complications; 3) live surgery performance; 4) theory and practice of clinical research; 5) comments on trainees' videos; and 6) questions, answers, and discussions. This retrospective before and after study surveyed 875 trainees from January 2015 to October 2020. Endpoints were general surgical skills (GSS), laparoscopic gastrectomy acceptance (LGA), and clinical research possibilities (CRP). The analysis took place in December 2021. RESULTS The response rate was 70.5% (617/875). ATP-LRG reportedly had a positive impact on the LRG practice of 99.5% (614/617) of trainees. Their GSS (before vs. after: 16.5 ± 3.7 vs. 20.3 ± 3.1, P < 0.001), LGA (4.2 ± 0.9 vs. 4.6 ± 0.7, P < 0.001), and CRP (2.6 ± 1.2 vs. 3.2 ± 1.1, P < 0.001) significantly improved. The improvement in GSS for those with professional titles of associate chief surgeons and below was significantly higher than that for chief surgeons (4.0 ± 3.0 vs 3.3 ± 2.4, P = 0.017), while those of LGA and CRP were not. The annual number of operations before training was negatively correlated with improvement in GSS (P < 0.001, Pearson's correlation coefficient: 0.14). Multivariate logistic regression showed that those with professional titles of associate chief surgeons and below (odds ratio [OR]: 1.719, 95% confidence interval [CI]: 1.038-2.846, P = 0.035), and with annual number of operations before training being <60, (OR: 5.257, 95% CI: 2.573-10.742, P < 0.001) were most prone to high-GSS improvement. CONCLUSION The nationwide ATP-LRG facilitates the improvement of trainees' GSS, LGA, and CRP levels. Surgeons with lower professional titles and fewer performed operations are most likely to improve their GSS through training.

Abstract
BACKGROUND Laparoscopic gastrectomy (LG) has been widely used for advanced gastric cancer (GC), and its resection extent is not limited to distal gastrectomy. However, the superiority of this minimally invasive approach remains controversial. This study aimed to evaluate the benefits and risks of LG on the short- and long-term outcomes compared with open gastrectomy (OG) for GC. MATERIALS AND METHODS A systematic literature search was performed to identify randomized controlled trials (RCTs) comparing LG and OG for treatment of GC. The primary outcomes were adverse events, recurrence, mortality, and the quality of life. The secondary outcomes included operation-relevant outcomes and postoperative recovery outcomes. We employed random-effects meta-analyses to pool results with Hartung-Knapp adjustment. The prediction interval (PI) was used to quantify the between-study heterogeneity. Meta-regression and subgroup analyses were performed to examine the potential sources of heterogeneity. RESULTS Twenty-eight studies involving 7643 patients were included. Most studies (22 out of 28) reported results from experienced surgeons. Compared to OG, LG was found to have the advantages of less blood loss, fewer postoperative complications, and faster recovery, but at the expense of lesser proximal resection margin length, longer operation time, and fewer retrieved lymph nodes. There were no significant differences for anastomosis-related complications, recurrence and survival and other outcomes between LG and OG. Significant between-study heterogeneity was observed. Body mass index (BMI) and age were two major sources of heterogeneity. CONCLUSIONS For experienced surgeons, LG is an alternative approach to OG for patients with GC. Patients with lower BMI and older age may benefit most from LG. Future studies are needed to confirm our findings in low-volume hospitals and for less-experienced surgeons. Future trials focusing on patient-important outcomes are warranted for clinical decision-making.

Laparoscopic vs. Open Gastrectomy for Locally Advanced Gastric Cancer: A Propensity Score-Matched Retrospective Case-Control Study. Curr Oncol 2022; 29:1840-1865. [PMID: 35323351 PMCID: PMC8947505 DOI: 10.3390/curroncol29030151] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 03/02/2022] [Accepted: 03/07/2022] [Indexed: 11/16/2022] Open
Abstract
Introduction: Minimally invasive surgery has been increasingly used in the treatment of gastric cancer. While laparoscopic gastrectomy has become standard therapy for early-stage gastric cancer, especially in Asian countries, the use of minimally invasive techniques has not attained the same widespread acceptance for the treatment of more advanced tumours, principally due to existing concerns about its feasibility and oncological adequacy. We aimed to examine the safety and oncological effectiveness of laparoscopic technique with radical intent for the treatment of patients with locally advanced gastric cancer by comparing short-term surgical and oncologic outcomes of laparoscopic versus open gastrectomy with D2 lymphadenectomy at two Western regional institutions. Methods: The trial was designed as a retrospective comparative matched case-control study for postoperative pathological diagnoses of locally advanced gastric carcinoma. Between January 2015 and September 2021, 120 consecutive patients who underwent curative-intent laparoscopic gastrectomy with D2 lymph node dissection were retrospectively recruited and compared with 120 patients who received open gastrectomy. In order to obtain a comparison that was as homogeneous as possible, the equal control group of pairing (1:1) patients submitted to open gastrectomy who matched those of the laparoscopic group was statistically generated by using a propensity matched score method. The following potential confounder factors were aligned: age, gender, Body Mass Index (BMI), comorbidity, ASA, adjuvant therapy, tumour location, type of gastrectomy, and pT stage. Patient demographics, operative findings, pathologic characteristics, and short-term outcomes were analyzed. Results: In the case-control study, the two groups were clearly comparable with respect to matched variables, as was expected given the intentional primary selective criteria. No statistically significant differences were revealed in overall complications (16.7% vs. 20.8%, p = 0.489), rate of reoperation (3.3% vs. 2.5%, p = 0.714), and mortality (4.2% vs. 3.3%, p = 0.987) within 30 days. Pulmonary infection and wound complications were observed more frequently in the OG group (0.8% vs. 4.2%, p < 0.01, for each of these two categories). Anastomotic and duodenal stump leakage occurred in 5.8% of the patients after laparoscopic gastrectomy and in 3.3% after open procedure (p = 0.072). The laparoscopic approach was associated with a significantly longer operative time (212 vs. 192 min, p < 0.05) but shorter postoperative length of stay (9.1 vs. 11.6 days, p < 0.001). The mean number of resected lymph nodes after D2 dissection (31.4 vs. 33.3, p = 0.134) and clearance of surgical margins (97.5% vs. 95.8%, p = 0.432) were equivalent between the groups. Conclusion: Laparoscopic gastrectomy with D2 nodal dissection appears to be safe and feasible in terms of perioperative morbidity for locally advanced gastric cancer, with comparable oncological equivalency with respect to traditional open surgery.

[PMID: 33585228 PMCID: PMC7874144 DOI: 10.3389/fonc.2020.607922] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Accepted: 12/04/2020] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND To compare laparoscopic proximal gastrectomy (LPG) and laparoscopic total gastrectomy (LTG) with regard to outcomes, including efficacy and safety, in patients with proximal gastric cancer. METHODS Original English-language articles comparing LPG and LTG for proximal gastric cancer up to November 2019 were systematically searched in the Embase, PubMed, Cochrane Library, Web of Knowledge, and ClinicalTrials.gov databases by two independent reviewers. Our main endpoints were surgery-related features (operation time, blood loss, harvested lymph nodes, and postoperative hospital stay), postoperative complications (anastomotic leakage, anastomotic bleeding, anastomotic stenosis, and reflux esophagitis), and oncologic outcomes (5-year overall survival and recurrent cancer). RESULTS Fourteen studies including a total of 1,282 cases (510 LPG and 772 LTG) were enrolled. Fewer lymph nodes were harvested (WMD = -13.33, 95% CI: -15.66 to -11.00, P < 0.00001) and more postoperative anastomotic stenosis (OR = 2.03, 95% CI: 1.21 to 3.39, P = 0.007) observed in LPG than LTG. There were no significant differences in other explored parameters between the two methods. However, based on a subgroup analysis of digestive tract reconstruction, LPG with esophagogastrostomy (LPG-EG) had shorter operative time (WMD = -42.51, 95% CI: -58.99 to -26.03, P < 0.00001), less intraoperative blood loss (WMD = -79.52, 95% CI: -116.63 to -42.41, P < 0.0001), and more reflux esophagitis (OR = 3.92, 95% CI: 1.56 to 9.83, P = 0.004) than was observed for LTG. There was no difference between LPG performed with the double tract anastomosis/double-flap technique (DT/DFT) and LTG. CONCLUSION LPG can be performed as an alternative to LTG for proximal gastric cancer, especially LPG-DT/DFT, with comparable safety and efficacy.

Abstract
Robotic systems were developed to overcome limitations of laparoscopic surgery with its mechanical advantages. Along with the technical advances, robotic gastrectomy for gastric cancer is increasing. However, the evidence regarding safety and efficacy for robotic gastrectomy for gastric cancer is not mature yet. Although studies are limited, it is evident that robotic gastrectomy has a longer operation and less blood loss compared with laparoscopic gastrectomy. Studies revealed long-term oncological outcomes after robotic gastrectomy was comparable to those after laparoscopic gastrectomy. Taken together, robotic gastrectomy with systemic lymph node dissection is suggested as a safe procedure with equivalent short- and long-term oncologic outcomes to either laparoscopic or open gastrectomy for the surgical treatment of gastric cancer. However, high cost is the most significant barrier to justify robotic surgery as a routine and standard treatment for patients with gastric cancer. In the meanwhile, robotic surgery will be expansively used as long as technologic developments continue.

Abstract
BACKGROUND The use of laparoscopic total gastrectomy for gastric cancer remains controversial. Our objective was to compare outcomes of laparoscopic total gastrectomy (LTG) vs. open total gastrectomy (OTG) for gastric adenocarcinoma using a national cancer database. METHODS The National Cancer Database (2010-2014) was analyzed for total gastrectomy cases performed for gastric adenocarcinoma. Patient demographics and surgical outcomes were stratified by stage and compared based on laparoscopic vs. open surgical approach. Primary outcome measures included 30-day and 90-day mortality and Kaplan-Meier curves to estimate long-term survival. RESULTS There were 2584 cases analyzed, including 592 (22.9%) stage I, 710 (27.5%) stage II, and 1282 (49.6%) stage III cases. The distribution of LTG vs. OTG cases was 156 (26.4%) vs. 436 (73.6%) for stage I, 163 (23.0%) vs. 547 (77.0%) for stage II, and 241 (18.8%) vs. 1041 (81.2%) for stage III. For all stages analyzed, there was no difference between laparoscopic vs. open approach for adjusted 30-day mortality (stage I: adjusted odds ratio (AOR) 0.52, p = 0.75; stage II: AOR 1.36, p > 0.99; stage III: AOR 0.46, p = 0.29) or 90-day mortality (stage I: AOR 0.46, p = 0.99; stage II: AOR 1.17, p = 0.99; stage III: 0.57, p = 0.29). There was no difference between LTG vs. OTG 5-year Kaplan-Meier estimated survival curves for any stage (stage I: p = 0.20; stage II: p = 0.83; stage III: p = 0.46). When compared to OTG, LTG had a similar hazard ratio (HR) for mortality (HR 0.89 p = 0.20). CONCLUSIONS Laparoscopic total gastrectomy and OTG have comparable 30-day mortality, 90-day mortality, and long-term survival.

Abstract
Background Enhanced recovery after surgery (ERAS) has been successfully applied in general surgery, especially in colorectal resection. However, the effect of ERAS in gastric cancer resection in current studies are inconsistent and most of which were single center retrospective ones. Thus, our study was aimed to evaluate the application of laparoscopy in ERAS for gastric cancer based on Chinese multicenter data. Methods The clinical and pathological data of patients who underwent radical gastric cancer resection at three Chinese medical centers between January, 2015 and December, 2017 were retrospectively analyzed. The current application of laparoscopy in ERAS for gastric cancer was evaluated. Results A total of 1,434 patients were involved in the final analysis. The operation time was 265.7±79.1 min, blood loss was 200 [5–1,300] mL, and the number of lymph nodes dissected was 26.4±12.9. Time to first ambulation, flatus, and liquid food intake were 2.1±1.3, 4.4±2.7, and 6.1±3.6 days, respectively, and postoperative hospital stay was 9.0±1.5 days. The incidence of postoperative complications, Clavien-Dindo score ≥ II, was 10.0%, and the rate of readmission within 30 days of discharge was 1.4%. Of the patients who underwent total gastrectomy, those in the laparoscopic group had a higher number of lymph nodes retrieved than those in the open group (P<0.05), and also had earlier ambulation, oral intake and first flatus, as well as a shorter postoperative hospital stay time than the open group. There were no significant differences in intraoperative blood loss or postoperative complications between the two groups (P>0.05). Of the patients who underwent distal gastrectomy, the laparoscopic group had a lower volume of blood loss, shorter postoperative hospital stay time, and earlier ambulation, oral intake, and first flatus than the open group, and had a similar number of lymph nodes dissected compared to the open group (P>0.05). Conclusions Laparoscopic surgery combined with ERAS can shorten the time to early ambulation, oral intake, and first flatus, and shorten the length of hospital stay. Laparoscopic surgery can achieve the same oncological outcomes as open surgery and is safe and feasible without increasing the incidence of postoperative complications.

Comparison of surgical outcomes among different methods of esophagojejunostomy in laparoscopic total gastrectomy for clinical stage I proximal gastric cancer: results of a single-arm multicenter phase II clinical trial in Korea, KLASS 03. Surg Endosc 2020; 35:1156-1163. [PMID: 32144557 DOI: 10.1007/s00464-020-07480-0] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Accepted: 02/26/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Laparoscopic distal gastrectomy for early gastric cancer has been widely accepted, but laparoscopic total gastrectomy has still not gained popularity because of technical difficulty and unsolved safety issue. We conducted a single-arm multicenter phase II clinical trial to evaluate the safety and the feasibility of laparoscopic total gastrectomy for clinical stage I proximal gastric cancer in terms of postoperative morbidity and mortality in Korea. The secondary endpoint of this trial was comparison of surgical outcomes among the groups that received different methods of esophagojejunostomy (EJ). METHODS The 160 patients of the full analysis set group were divided into three groups according to the method of EJ, the extracorporeal circular stapling group (EC; n = 45), the intracorporeal circular stapling group (IC; n = 64), and the intracorporeal linear stapling group (IL; n = 51). The clinicopathologic characteristics and the surgical outcomes were compared among these three groups. RESULTS There were no significant differences in the early complication rates among the three groups (26.7% vs. 18.8% vs. 17.6%, EC vs. IC vs. IL; p = 0.516). The length of mini-laparotomy incision was significantly longer in the EC group than in the IC or IL group. The anastomosis time was significantly shorter in the EC group than in the IL group. The time to first flatus was significantly shorter in the IL group than in the EC group. The long-term complication rate was not significantly different among the three groups (4.4% vs. 12.7% vs. 7.8%; EC vs. IC vs. IL; p = 0.359), however, the long-term incidence of EJ stenosis in IC group (10.9%) was significantly higher than in EC (0%) and IL (2.0%) groups (p = 0.020). CONCLUSIONS The extracorporeal circular stapling and the intracorporeal linear stapling were safe and feasible in laparoscopic total gastrectomy, however, intracorporeal circular stapling increased EJ stenosis.

Surgical Outcomes and Follow-Up Results of 100 Cases of Laparoscopic Total Gastrectomy Using the Overlap Method with Stapled Closure. THE JOURNAL OF MINIMALLY INVASIVE SURGERY 2019; 22:150-156. [PMID: 35601369 PMCID: PMC8980157 DOI: 10.7602/jmis.2019.22.4.150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/27/2019] [Revised: 07/12/2019] [Accepted: 08/26/2019] [Indexed: 11/24/2022]
Abstract
Purpose The overlap method is one of the most popular procedures for construction of an esophagojejunostomy and its common entry is usually closed with sutures. This study aimed to report long-term complications and surgical outcomes of the overlap method with stapled closure (OMSC), to compare them with those of laparoscopy-assisted total gastrectomy (LATG), and to analyze a learning curve. Methods Between January 2015 and August 2017, 100 consecutive patients underwent laparoscopic total gastrectomy with OMSC for gastric cancer and the patients’ medical records were reviewed. Their clinicopathologic characteristics, surgical outcomes, and long-term complications were investigated and compared with those of the LATG group. A learning curve of OMSC was analyzed using the Exponentially Weighted Moving Average chart. Results The overall duration of surgery was shorter in the LATG group; however, there was no difference in patients with early gastric cancer. Hospital admission was shorter and the pain scale was lower in the OMSC group. There was no difference in the number of harvested lymph nodes, date of flatus, or incidence of postoperative morbidity. Both groups showed no duodenal stump leakage, anastomosis-related complications, recurrence, or mortality during the follow-up period. Petersen hernia was a notable long-term event following OMSC compared with LATG. At least 27 cases of surgery were required to reach a plateau in terms of surgery duration for OMSC. Conclusion OMSC is a safe option for the treatment of gastric cancer and has favorable long-term results and surgical outcomes. Closure of mesenteric defects and Petersen space should be considered.

Abstract
BACKGROUND Presently, there is no consensus as to what procedure of intracorporeal esophagojejunostomy (EJS) in totally laparoscopic total gastrectomy (TLTG) is best to reduce postoperative complications. The aim of this study was to demonstrate the superiority of linear stapled reconstruction in terms of anastomotic-related complications for EJS in TLTG. METHODS We collected data on 829 consecutive gastric cancer patients who underwent TLTG reconstructed by the Roux-en-Y method with radical lymphadenectomy between January 2010 and December 2016 in 13 hospitals. The patients were divided into two groups according to reconstruction method and matched by propensity score. Postoperative EJS-related complications were compared between the linear stapler (LS) and the circular stapler (CS) groups. RESULTS After matching, data from 196 patients in each group were analyzed. The overall incidence of EJS-related complications was significantly lower in the LS group than in the CS group (4.1% vs. 11.7%, p = 0.008). The incidence of EJS anastomotic stenosis during the first year after surgery was significantly lower in the LS group than in the CS group (1.5% vs. 7.1%, p = 0.011). The incidence of EJS bleeding did not differ significantly between the groups, although no bleeding was observed in the LS group (0% vs. 2.0%, p = 0.123). The incidence of EJS leakage did not differ significantly between the groups (2.6% vs. 3.6%, p = 0.771). CONCLUSION The use of linear stapled reconstruction is safer than the use of circular stapled reconstruction for intracorporeal EJS in TLTG because of its lower risks of stenosis.

Abstract
Purpose No standard technique has been established for esophagojejunal anastomosis during laparoscopic total gastrectomy (LTG) for gastric cancer owing to the technical difficulty and high complication rate of this procedure. This study was performed to compare the short-term outcomes of circular and linear stapling methods after LTG. Materials and Methods A total of 106 patients treated between July 2010 and July 2018 were divided into 2 groups according to the following anastomosis procedures: hemi-double-stapling technique (HDST; circular stapling method; group C, n=77) or overlap method (linear stapling method; group L, n= 29). The clinicopathological features and postoperative outcomes, including complications, were analyzed. Multivariate analysis was performed using a logistic regression model to identify the independent risk factors for anastomotic complications. Results The incidence of anastomotic complications was significantly higher in group C than in group L (28.0% vs. 6.9%, P=0.031). The incidence of anastomosis leakage did not differ between the groups (6.5% vs. 6.9%, P=1.000). However, anastomosis stricture occurred only in group C (13% vs. 0%, P=0.018). Multivariate analysis showed that the anastomosis type was significantly related to the risk of anastomotic complications (P=0.045). Conclusions The overlap method was superior to the HDST with respect to anastomotic complications, especially anastomosis stricture.

Surgical outcomes and learning curve analysis of robotic gastrectomy for gastric cancer: Multidimensional analysis compared with three‑dimensional high‑definition laparoscopic gastrectomy. Int J Oncol 2019; 55:733-744. [PMID: 31364736 DOI: 10.3892/ijo.2019.4851] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2019] [Accepted: 06/04/2019] [Indexed: 11/06/2022] Open
Abstract
The present ambispective cohort study was performed to compare the short‑term surgical outcomes, including financial cost and surgeons' acceptance, of robotic versus three‑dimensional high‑definition (3D‑HD) laparoscopic gastrectomy for patients with gastric cancer (GC). Between 2011 and 2017, 517 patients with GC were enrolled for treatment with either robotic gastrectomy [408 patients, including 73 treated by one of the authors (LC)] or 3D‑HD laparoscopic gastrectomy (109 patients, including 71 treated by LC). The cumulative summation method was developed to analyze the learning curves of robotic and 3D‑HD laparoscopic gastrectomy performed by LC. In the analysis of all 517 patients, there were no significant differences in the clinicopathological characteristics between the two treatment groups, with the exception of smoking status (P<0.001). The robotic group had a shorter operative time (OT; 209 vs. 228 min, P=0.004), fewer postoperative days (PODs) to first flatus (3 vs. 4 days, P=0.025), more PODs to removal of the drainage and nasogastric tubes (12 vs. 9 days, P=0.001; 6 vs. 4 days, P=0.001, respectively), and more postoperative complications (21.3 vs. 9.2%, P=0.003). Comparison of these short‑term outcomes of robotic and 3D‑HD laparoscopic gastrectomy performed by LC (144 patients) revealed that only the number of retrieved lymph nodes (27 in the robotic group vs. 33 in the 3D‑HD group; P=0.038) and PODs to removal of the nasogastric tube (5 days in the robotic group vs. 3 days in the 3D‑HD group; P<0.001) were significantly different. The OT stabilized after around 21 robotic gastrectomy procedures and 19 3D‑HD laparoscopic gastrectomy procedures. The cost‑effectiveness analysis revealed that robotic gastrectomy had a significantly higher total cost than 3D‑HD laparoscopic gastrectomy (124,907 vs. 94,395 RMB, P<0.001). With comparable surgical outcomes, lower financial cost and higher surgeons' acceptance, 3D‑HD laparoscopic gastrectomy is highly recommended as a minimally invasive surgical method for patients with GC prior to the popularization of robotic surgery.

Difference in the short-term outcomes of laparoscopic gastrectomy for gastric carcinoma between the east and west: a retrospective study from the IMIGASTRIC trial. J Cancer 2019; 10:4106-4113. [PMID: 31417655 PMCID: PMC6692614 DOI: 10.7150/jca.31192] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2018] [Accepted: 04/23/2019] [Indexed: 12/23/2022] Open
Abstract
Purpose: To compare the clinicopathologic data and short-term surgical outcomes of laparoscopic gastrectomy (LG) for gastric cancer (GC) between the east and west. Methods: Patient demographics, surgical procedures, pathological information, and postoperative recovery were compared among gastric cancer patients who underwent LG in the clinical trial of IMIGASTRIC (NCT02325453) between 2009 and 2016. Results: More younger males, higher BMI, lower ASA score and less neoadjvant chemotherapy were evident in east patient cohort. Eastern patients had a higher proportion of proximal, differentiated and advanced gastric cancers. More total gastrectomies, larger extent of lymph node (LN) dissection, and higher number of retrieved LNs were found in the eastern patients. However, more Roux-en-Y anastomosis procedures during distal gastrectomy and intra-corporeal anastomosis were performed in the western patients. The west patients showed faster postoperative recovery than the eastern patients. The mortality rates of the western patients were comparable to those of the eastern patients. However, fewer III-IV complications were evident in the eastern centers. Multivariate analyses revealed that an elderly age, higher ASA score, and more blood loss were the significant independent risk factors of postoperative complications for eastern patients. However, for the western patients, the independent risk factors were neoadjuvant therapy, more retrieval LNs, and pT3-4 stage. Conclusions: The selections and short-term surgical outcomes of LG for GC were widely different between East and West. To obtain more objective and accurate results, these differences should be considered in future international prospective studies.

Abstract
BACKGROUND Minimally invasive resection for upper gastrointestinal tumors has been associated with favorable results. However, the role of laparoscopic surgery (LS) in the multimodal treatment of patients with advanced adenocarcinoma of the stomach or gastroesophageal junction needs further investigation. METHODS Clinicopathological data of patients who underwent gastrectomy between 2005 and 2017 were assessed. Outcomes of patients undergoing LS were compared with those of patients treated with a conventional open resection (OR) using a 1:1 propensity score matching analysis. RESULTS Curative resection for adenocarcinoma of the stomach or gastroesophageal junction was performed in 417 patients during the study period. Beginning in June 2014, the majority of patients underwent LS (n = 72) and they were matched with 72 patients who were treated with an OR. The majority of patients treated with LS (89%) had advanced cancer (UICC stages II and III) and 82% of them received neoadjuvant chemotherapy. LS was significantly associated with a higher number of harvested lymph nodes (26 (9-62) vs. 21 (4-46), P = .007), a lower 90-day major complication rate (13 vs. 26%, P = .035), and a lower length of hospital stay (14 vs. 16 days, P = .001). After a median follow-up time of 32 months, 1-year overall survival rate was higher after LS than after OR (93 vs. 74%, P = .126); however, results did not reach statistical significance. CONCLUSION LS for adenocarcinoma of the stomach or gastroesophageal junction is feasible and significantly reduces major postoperative morbidity resulting in a reduced length of hospital stay. Therefore, LS should be preferably considered for the curative treatment of patients with these malignancies.

Abstract
Introduction Gastric cancer is a worldwide health concern, being one of the five most common malignant neoplasms worldwide. Currently, an open approach is the gold standard for surgical treatment. Incorporation of laparoscopy as a method of choice for gastric resections remains controversial because of limited evidence of eligibility. To date, there are no high-quality randomized quality trials on totally laparoscopic D2 total gastrectomies. Aim The aim of this study was to assess currently available literature and provide meta-analysis on acquired data regarding short-term outcomes with a subgroup analysis of western and eastern studies. Materials and methods We performed a systematic review and meta-analysis according to the PRISMA guidelines. The primary outcomes of interest were morbidity and short-term complications. Results An initial reference search yielded 3,073 articles. Finally, we chose eight studies covering 1,582 patients that we included in the quantitative analysis. We did not find statistical differences regarding operative time, anastomotic leakage, surgical site infection, cardiac complications, pulmonary complications, or number of harvested lymph nodes. We found significant differences regarding length of hospital stay and morbidity in the Asian population. Conclusion This systematic review indicates that a laparoscopic approach for D2 total gastrectomy does not increase morbidity. Furthermore, it allows for a shorter hospital stay. However, more randomized controlled trials are required to fully assess this approach because available data are of limited quality.

Abstract
Purpose With increasing life expectancy, the presence of comorbidities has become a major concern in elderly patients who require surgery. However, little is known about the impact of different comorbidities on the outcomes of laparoscopic total gastrectomy (LTG). In this study, we investigated the impact of comorbidities on postoperative complications in patients undergoing LTG for gastric carcinoma. Materials and Methods We retrospectively reviewed the cases of 303 consecutive patients who underwent LTG for gastric carcinoma between 2005 and 2016. The associations between each comorbidity and postoperative complications were assessed using univariate and multivariate analyses. Results A total of 189 patients (62.4%) had one or more comorbidities. Hypertension was the most common comorbidity (37.0%), followed by diabetes mellitus (17.8%), chronic viral hepatitis (2.6%), liver cirrhosis (2.6%), and pulmonary (27.1%), ischemic heart (3.3%), and cerebrovascular diseases (2.3%). The overall postoperative morbidity and mortality rates were 20.1% and 1.0%, respectively. Patients with pulmonary disease significantly showed higher complication rates than those without comorbidities (32.9% vs. 14.9%, respectively, P=0.003); patient with other comorbidities showed no significant difference in the incidence of LTG-related complications. During univariate and multivariate analyses, pulmonary disease was found to be an independent predictive factor for postoperative complications (odds ratio, 2.14; 95% confidence interval, 1.03-4.64), along with old age and intraoperative bleeding. Conclusions Among the various comorbidities investigated, patients with pulmonary disease had a significantly higher risk of postoperative complications after LTG. Proper perioperative care for optimizing pulmonary function may be required for patients with pulmonary disease.

Abstract
BACKGROUND Minimally invasive gastrectomy has been introduced in Western populations during the last decade. As minimally invasive distal gastrectomy (MIDG) versus total gastrectomy (MITG) are procedures with a different complexity, outcomes may differ. The aim of this population-based cohort study was to evaluate the safety of MIDG and MITG. MATERIALS AND METHODS All patients who underwent potentially curative gastrectomy for gastric adenocarcinoma were included from the Dutch Upper GI Cancer Audit (2011-2016). Propensity score matching was applied to create comparable groups of patients receiving open distal gastrectomy (ODG) versus MIDG and open total gastrectomy (OTG) versus MITG, using patient and tumor characteristics. Postoperative outcomes and short-term oncological outcomes were appraised. RESULTS Of the 1970 eligible patients, 1138 underwent distal gastrectomy and 832 underwent total gastrectomy. For distal gastrectomy, 390 ODG were matched to 288 MIDG patients. Although overall postoperative morbidity and mortality were similar, patients who underwent MIDG encountered less intra-abdominal abscesses (4% vs. 1%, p = 0.039) and wound complications (6% vs. 2%, p = 0.021). The median hospital stay was shorter after MIDGs (9 vs. 7 days, p < 0.001). For total gastrectomy, 323 OTG patients were matched to 258 MITG patients. Overall postoperative morbidity, mortality and hospital stay were similar, whereas the anastomotic leakage rate was higher after MITGs (11% vs. 17%, p = 0.030). Short-term oncological outcomes between both groups were equal for distal and total gastrectomy. CONCLUSION Benefits of MIG during the early introduction were demonstrated for distal gastrectomy but not for total gastrectomy. An increased anastomotic leakage rate was encountered for MITG.

Abstract
OBJECTIVE To understand how practicing surgeons utilize available training methods, which methods are perceived as effective, and important barriers to using more effective methods. DESIGN Online survey designed to characterize surgeon utilization and perception of available training methods. SETTING Two large Midwestern academic health centers. PARTICIPANTS 150 faculty surgeons. METHODS Nominal values were compared using a McNemar's Test and Likert-like values were compared using a paired t-test (IBM SPSS Statistics v. 21.0; New York, NY). RESULTS Survey response rate was 81% (122/150). 98% of surgeons reported learning a new procedure or technology after formal training. Many surgeons reported scrubbing in expert cases (78%) and self-directed study (66%), while few surgeons (6%) completed a mini-fellowship. The modalities used most commonly were scrubbing in expert cases (34%) and self-directed study (27%). Few surgeons (7%) believed self-directed study would be most effective, whereas 31% and 16% believed operating under supervision and mini-fellowships would be most effective, respectively. Surgeons believed more effective methods "would require too much time" or they had "confidence in their ability to implement safely." CONCLUSIONS Practicing surgeons use a variety of training methods when learning new procedures and technologies, and there is disconnect between commonly used training methods and those deemed most effective. Confidence in surgeon's ability was cited as a reason for this discrepancy; and surgeons found time associated with more effective methods to be prohibitive.

Abstract
BACKGROUND Laparoscopic (laparoscopy-assisted) gastrectomy (LG) has several short-term benefits as compared with open distal gastrectomy (OG) in patients with advanced gastric cancer (AGC). Survival rates did not differ significantly between LG and OG in retrospective studies of AGC, although some studies included unmatched groups of patients or patients with AGC who had a preoperative diagnosis of early gastric cancer. The aim of present study was to compare the short- and long-term outcomes of patients with AGC who underwent LG with those of patients with AGC who underwent OG using a propensity-score matching analysis. METHODS The study group comprised patients with a preoperative and pathologically confirmed diagnosis of AGC who underwent LG or OG with lymphadenectomy between January 2001 and December 2012 in our hospital. To minimize bias between the LG and OG groups, propensity scores were calculated using a logistic regression model and the following variables: sex, age, body-mass index, American Society of Anesthesiologists physical status class, type of gastrectomy, and clinical and pathological tumor stage. After propensity-score matching, 104 patients (52 who underwent LG and 52 who underwent OG) were studied. RESULTS LG was associated with significantly earlier initiation of food intake (p <0.01) and a significantly shorter period of postoperative hospitalization (p <0.01). The incidence of all-grade overall, surgical, and medical complications did not differ significantly between the LG group and OG group (p = 0.24, p = 0.12, and p >0.99). Overall and relapse-free survival also did not differ between the LG group and OG group (p = 0.96, p = 0.91). In each tumor stage, overall and relapse-free survival did not differ significantly between the LG group and OG group. CONCLUSION LG can be a feasible treatment that is beneficial in terms of earlier recovery after operation and can be expected to result in similar survival as OG in patients with AGC.

Successful treatment of refractory complete separation of an esophagojejunal anastomosis after laparoscopic total gastrectomy: a case report. BMC Res Notes 2017; 10:267.

Abstract
Background Anastomotic leakage after total gastrectomy occurs despite improvements in surgical techniques and patient management. Although many cases of dehiscence can be managed non-operatively, major leakage requires a second surgery and can potentially lead to death. Therefore, accurate and immediate diagnosis and treatment are essential. Case presentation In this report, we describe a 66-year-old Japanese man who was diagnosed with a complete separation of an esophagojejunal anastomosis after laparoscopic total gastrectomy with oral contrast radiography using Gastrografin®. The severe complication was successfully treated by re-anastomosis after two emergency drainage surgeries. After the second surgery, the esophageal end formed a fistula with the jejunum, but balloon dilation failed to open the fistula. Therefore, oral ingestion and conservative treatment were considered unsuitable, and we performed esophagojejunal re-anastomosis 7 months after the first surgery. At a follow-up examination 2 years after re-anastomosis, the patient weighed 47 kg, and his ingestion had recovered to 80% of that before surgery. Conclusions Complete separation of an esophagojejunal anastomosis is a rare but severe complication of total gastrectomy. Therefore, we consider that once separation is diagnosed, aggressive and urgent re-operation and effective drainage are useful. Moreover, it is necessary to take great care to minimize the operative morbidity associated with esophagojejunal anastomosis.

Impact of stepwise introduction of esophagojejunostomy during laparoscopic total gastrectomy: a single-center experience in Japan. Ann Gastroenterol 2017; 30:564-570. [PMID: 28845113 PMCID: PMC5566778 DOI: 10.20524/aog.2017.0157] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2017] [Accepted: 04/12/2017] [Indexed: 12/19/2022] Open
Abstract
Background The number of laparoscopic gastrectomies performed in Japan is increasing with the development of laparoscopic and surgical instruments. However, laparoscopic total gastrectomy is developing relatively slowly because of technical difficulties, particularly in esophagojejunostomy. Methods We retrospectively reviewed 83 patients with early gastric cancer in the upper portion of the stomach who underwent laparoscopic total gastrectomy between April 2007 and March 2016. We classified the patients into three periods, mainly on the basis of the esophagojejunostomy procedures performed: first period, various conventional procedures based on the physicians’ choice (n=14); second period, transoral method (n=51); and third period, fully intracorporeal technique (n=18). We evaluated the clinical impact of a stepwise introduction of unfamiliar new methods during laparoscopic total gastrectomy. Results Between the first and second periods, there were significant differences in the blood loss volume, number of harvested lymph nodes, frequency of conversion to open surgery, and postoperative hospital stay. The number of harvested lymph nodes was significantly higher in the third than in the second period, with no detriment to other intraoperative or postoperative factors. Conclusion The use of a unified surgical method for esophagojejunostomy seems to be the key to a successful and advantageous laparoscopic total gastrectomy. Stepwise introduction of a well-established technique of esophagojejunostomy during laparoscopic total gastrectomy will benefit patients, as shown, for example, by the higher number of dissected lymph nodes in the present study. However, a protracted learning curve is required.

Abstract
After total gastrectomy, anastomosis-related complications such as leak or stricture can be highly morbid. Between July 2005 and December 2015, a linear-stapled side-to-side esophagojejunostomy with hand-sewn closure of the common enterotomy (modified Orringer technique) was used for Roux-en-Y reconstruction after prophylactic total gastrectomy in 22 germline CDH1 mutation carriers and after therapeutic total gastrectomy in 18 patients diagnosed with gastric adenocarcinoma. All operations were performed by the same surgeon. No patient in either cohort developed a clinically evident anastomotic leak, one patient (2.5%) developed a contained radiographic leak that healed without intervention, and one patient (2.5%) developed an anastomotic stricture treated by endoscopic dilatation 7 months after operation. These rates were lower than radiographic leak and stricture rates in a comparison group of 32 patients who received a completely hand-sewn esophagojejunostomy (6.3 and 3.1%, respectively). Here, we describe how to perform the linear-stapled esophagojejunostomy anastomosis.

Abstract
Minimally invasive techniques in transhiatal esophagectomy (THE) were introduced to reduce morbidity and enhance postoperative recovery. Aim of this study was to systematically review the current status and possible beneficial effects of the minimally invasive approach in THE. A systematic search was performed in PubMed, the Cochrane Library, and Embase to identify English articles published on laparoscopic THE. Comparative cohort studies were included for critical appraisal. Data describing perioperative and oncological outcomes were analyzed. A total of four comparative cohort studies that compared laparoscopic THE (n = 122) with open THE (n = 144) and four noncomparative cohort studies reporting on laparoscopic THE (n = 212) were included in this review. Median blood loss was significantly lower in the laparoscopic group in all studies (100-500 vs. 526-900 mL). Length of hospital stay was also significantly shorter for the laparoscopic approach in all studies (9-13 vs. 12-16 days). One study reported less major postoperative complications after laparoscopic THE (12 vs. 23%), in the other studies no differences were found. Also no differences were found with regard to operating time, postoperative morbidity, radicality, and lymph node retrieval. Based on these pioneer studies, laparoscopic THE was demonstrated to be safe and feasible with evidence of reduced blood loss and shorter hospital stays. However, level 1 evidence is lacking and further research is warranted to confirm these findings and also to evaluate long-term oncologic outcomes.

Abstract
Background. Some meta-analyses of case-controlled studies (CCSs) have shown that laparoscopic or laparoscopy-assisted total gastrectomy (LTG) had some short-term advantages over open total gastrectomy (OTG). However, postoperative complications differed somewhat among the meta-analyses, and some CCSs included in the meta-analyses had mismatched factors between LTG and OTG. Methods. CCSs comparing postoperative complications between LTG and OTG were identified in PubMed and Embase. Studies matched for patients' status, tumor stage, and the extents of lymph-node dissection were included. Outcomes of interest, such as anastomotic, other intra-abdominal, wound, and pulmonary complications, were evaluated in a meta-analysis performed using Review Manager version 5.3 software. Result. This meta-analysis included a total of 2,560 patients (LTG, 1,073 patients; OTG, 1,487 patients) from 15 CCSs. Wound complications were significantly less frequent in LTG than in OTG (n = 2,430; odds ratio [OR] 0.30, 95% confidence interval [CI] 0.29-0.85, P = 0.01, I2 = 0%, and OR 0.46, 95% CI 0.17-0.52, P < 0.0001, I2 = 0%). However, the incidence of anastomotic complications was slightly but not significantly higher in LTG than in OTG (n = 2,560; OR 1.44, 95% CI 0.96-2.16, P = 0.08, I2 = 0%). Conclusion. LTG was associated with a lower incidence of wound-related postoperative complications than was OTG in this meta-analysis of CCSs; however, some concern remains about anastomotic problems associated with LTG.

Abstract
BACKGROUND Hospital volume is known to be a crucial factor in reducing postoperative morbidity and mortality in laparoscopic gastrectomy for gastric cancer. However, it is unclear whether surgeon's individual experience can overcome the effect of hospital volume. METHODS Clinicopathologic data of initial 50 laparoscopic gastrectomy cases were collected from six gastric cancer surgeons. Half of the six surgeons worked in high-volume centers, and the other half worked in low-volume hospitals. Perioperative outcomes were compared between the high-volume centers and the low-volume hospitals. RESULTS Three low-volume hospitals in this study contained significantly more male and older patients with a higher American Society of Anesthesiologists score than high-volume centers. Although high- and low-volume hospitals mainly used laparoscopy-assisted and totally laparoscopic approach, respectively, there were no differences between the two groups in the extent of resection, operating time, estimated blood loss, and number of collected lymph nodes. Postoperative recovery such as duration to soft diet and hospital stay did not differ between the high- and the low-volume hospitals. No significant difference was found in postoperative morbidities by Clavien-Dindo classification. There was no mortality reported in both groups of the enrolled hospitals. CONCLUSIONS Hospital volume is not a decisive factor in affecting postoperative morbidity and mortality for well-trained beginners in laparoscopic surgery for gastric cancer.

Abstract
BACKGROUND Morbidity after gastrectomy remains high. The potentially modifiable risk factors have not been well described. This study considers a series of potentially modifiable patient-specific and perioperative characteristics that could be considered to reduce morbidity and mortality after gastrectomy. METHODS This retrospective cohort study includes adults in the ACS NSQIP PUF dataset who underwent gastrectomy between 2011 and 2013. Sequential multivariable models were used to estimate effects of clinical covariates on study outcomes including morbidity, mortality, readmission, and reoperation. RESULTS Three thousand six hundred and seventy-eight patients underwent gastrectomy. A majority of patients had distal gastrectomy (N = 2,799, 76.1 %) and had resection for malignancy (N = 2,316, 63.0 %). Seven hundred and ninety-eight patients (21.7 %) experienced a major complication. Reoperation was required in 290 patients (7.9 %). Thirty-day mortality was 5.2 %. Age (OR = 1.01, 95 % CI = 1.01-1.02, p = 0.001), preoperative malnutrition (OR = 1.65, 95 % CI = 1.35-2.02, p < 0.001), total gastrectomy (OR = 1.63, 95 % CI = 1.31-2.03, p < 0.001), benign indication for resection (OR = 1.60, 95 % CI = 1.29-1.97, p < 0.001), blood transfusion (OR = 2.57, 95 % CI = 2.10-3.13, p < 0.001), and intraoperative placement of a feeding tubes (OR = 1.28, 95 % CI = 1.00-1.62, p = 0.047) were independently associated with increased risk of morbidity. Association between tobacco use and morbidity was statistically marginal (OR = 1.23, 95 % CI = 0.99-1.53, p = 0.064). All-cause postoperative morbidity had significant associations with reoperation, readmission, and mortality (all p < 0.001). CONCLUSIONS Mitigation of perioperative risk factors including smoking and malnutrition as well as identified operative considerations may improve outcomes after gastrectomy. Postoperative morbidity has the strongest association with other measures of poor outcome: reoperation, readmission, and mortality.

Abstract
BACKGROUND Surgical site infection (SSI), particularly organ/space SSI, remains a clinically important issue even after laparoscopic gastrectomy (LG) for gastric cancer (GC). This study aimed to identify specific clinical and surgical factors associated with organ/space SSI after LG. METHODS This was a retrospective study of 407 patients who underwent LG for clinical stage I GC. SSI was defined according to the National Nosocomial Infection Surveillance System. The incidence and treatment outcomes of either incisional or organ/space SSI after LG were examined, and the risk factors for each type of SSI were identified using univariate and multivariate analyses. RESULTS Organ/space SSI was observed in 21 patients (5.2 %), while incisional SSI was detected in 18 patients (4.4 %). Although no mortality was observed, the occurrence of either incisional or organ/space SSI significantly prolonged postoperative hospital stays (p = 0.000 and 0.000, respectively); however, organ/space SSI required more re-operations and re-admissions, and eventually longer total hospital stays than incisional SSI (p = 0.036). Intra-abdominal abscess around the pancreas was the main cause of organ/space SSI, while no anastomotic leakage was observed. Multivariate analyses identified male gender (odds ratio (OR) 3.385; 95 % confidence interval (CI) 1.073-15.07, p = 0.037), chronic liver disease (OR 8.897; 95 % CI 2.502-28.99, p = 0.001), and total gastrectomy (TG) (OR 3.817; 95 % CI 1.380-10.24, p = 0.011) as independent risk factors for organ/space SSI, while TG (OR 3.130; 95 % CI 1.102-8.768, p = 0.033) and operation time ≥320 min (OR 3.732; 95 % CI 1.109-16.98, p = 0.033) were independently associated with incisional SSI. CONCLUSIONS Male gender, chronic liver disease, and TG are independent risk factors for organ/space SSI after LG for GC; thus, meticulous surgical procedures need to be performed among patients with these specific risk factors.

Abstract
Minimally invasive surgical techniques for gastric cancer are gaining more acceptance worldwide as an alternative to open resection. In order to assess the role of minimally invasive and open techniques in total gastrectomy for cancer, a systematic review and meta-analysis was performed. Articles comparing minimally invasive versus open total gastrectomy were reviewed, collected from the Medline, Embase, and Cochrane databases. Two different authors (JS and NW) independently selected and assessed the articles. Outcomes regarding operative results, postoperative recovery, morbidity, mortality, and oncological outcomes were analyzed. Statistical analysis portrayed the weighted mean difference (WMD) with a 95 % confidence interval and odds ratio (OR). Out of 1242 papers, 12 studies were selected, including a total of 1360 patients, of which 592 underwent minimally invasive total gastrectomy (MITG). Compared to open total gastrectomy (OTG), MITG showed a longer operation time (WMD: 48.06 min, P < 0.00001), less operative blood loss (WMD: −160.70 mL, P < 0.00001), faster postoperative recovery, measured as shorter time to first flatus (WMD −1.05 days, P < 0.00001), shorter length of hospital stay (WMD: −2.43 days, P = 0.0002), less postoperative complications (OR 0.66, P = 0.02), similar mortality rates (OR 0.60, P = 0.52), and similar rates in lymph node yield (WMD −2.30, P = 0.06). Minimally invasive total gastrectomy showed faster postoperative recovery and less postoperative complications, whereas completeness of the resection was similar in both groups. Duration of surgery was longer in the minimally invasive group. Only comparative non-randomized studies were available, further emphasizing the need for a prospective randomized trial comparing MITG and OTG.

Abstract
BACKGROUND The critical risk factors for surgical site infection (SSI) after laparoscopic total gastrectomy (LTG) remain unclear. We analyzed the association between body composition and SSI after LTG. METHODS We performed a retrospective study of patients with gastric cancer who underwent LTG between March 2006 and October 2014 at Kyoto University Hospital, Japan. Visceral fat area and skeletal muscle mass were assessed from preoperative computed tomography scans to define sarcopenia and obesity. Patients were classified into one of four body composition categories according to the presence or absence of sarcopenia or obesity. The incidence of SSI was compared between the four body composition categories. RESULTS Of the 157 eligible patients, 45 (24 %) fulfilled the criteria for sarcopenic obesity, 28 (18 %) for nonsarcopenic obesity, 52 (33 %) for sarcopenic nonobesity, and 32 (20 %) for nonsarcopenic nonobesity. Thirty-two patients developed SSI (overall incidence rate, 20 %). The incidence of SSI in each body composition category was 33, 25, 13, and 9 %, respectively (P = 0.03). Multivariate logistic regression analysis showed that only sarcopenic obesity was associated with an increased incidence of SSI (odds ratio 4.59, 95 % confidence interval 1.18-17.78, P = 0.028). CONCLUSIONS Sarcopenic obesity is an independent risk factor for the development of SSI after LTG.

Abstract
AIM: To evaluate the current status of gastric cancer surgery worldwide.
METHODS: An international cross-sectional survey on gastric cancer surgery was performed amongst international upper gastro-intestinal surgeons. All surgical members of the International Gastric Cancer Association were invited by e-mail to participate. An English web-based survey had to be filled in with regard to their surgical preferences. Questions asked included hospital volume, the use of neoadjuvant treatment, preferred surgical approach, extent of the lymphadenectomy and preferred anastomotic technique. The invitations were sent in September 2013 and the survey was closed in January 2014.
RESULTS: The corresponding specific response rate was 227/615 (37%). The majority of respondents: originated from Asia (54%), performed > 21 gastrectomies per year (79%) and used neoadjuvant chemotherapy (73%). An open surgical procedure was performed by the majority of surgeons for distal gastrectomy for advanced cancer (91%) and total gastrectomy for both early and advanced cancer (52% and 94%). A minimally invasive procedure was preferred for distal gastrectomy for early cancer (65%). In Asia surgeons preferred a minimally invasive procedure for total gastrectomy for early cancer also (63%). A D1+ lymphadenectomy was preferred in early gastric cancer (52% for distal, 54% for total gastrectomy) and a D2 lymphadenectomy was preferred in advanced gastric cancer (93% for distal, 92% for total gastrectomy)
CONCLUSION: Surgical preferences for gastric cancer surgery vary between surgeons worldwide. Although the majority of surgeons use neoadjuvant chemotherapy, minimally invasive techniques are still not widely adapted.

Abstract
OBJECTIVE To evaluate the safety, feasibility and clinical results of the modified delta-shaped gastroduodenostomy (MDSG) in totally laparoscopic distal gastrectomy (TLDG) for gastric cancer (GC). METHODS We performed a case-control and case-matched study enrolling 642 patients with GC undergoing laparoscopic distal gastrectomy with Billroth-I anastomosis from January 2011 to December 2014. TLDG with MDSG was performed in 158 patients (Group TL), and laparoscopy-assisted distal gastrectomy with circular anastomosis was performed in 484 patients (Group LA). One-to-one propensity score matching (PSM) was performed to compare the clinicopathological characteristics between the two groups. RESULTS Patients with smaller tumors or stage I cancer were more likely to receive TLDG (P < 0.05). In the propensity-matched analysis of 143 pairs, there were no differences in demographic and pathologic characteristics between groups (all P < 0.05). All patients successfully underwent laparoscopic radical distal gastrectomy. Before PSM, Group TL had more dissected lymph nodes (LNs), a longer time to first fluid diet and a longer postoperative length of stay than Group LA (all P < 0.05). After PSM, except for the fact that more dissected LNs were obtained in Group LA (P < 0.05), no difference was found in the intraoperative and postoperative outcomes between the groups (all P > 0.05). The postoperative complications were similar in both groups (all P > 0.05). Stratification analysis performed after PSM showed that in early GC, no difference was observed in intraoperative and postoperative outcomes between the groups (all P > 0.05). However, in locally advanced GC, Group TL had more dissected LNs and a higher rate of postoperative complications (both P < 0.05). Univariate analysis carried out in locally advanced cases after PSM showed that the body mass index (BMI), the method of digestive tract reconstruction and Charlson's score were significant factors that affected postoperative morbidity (all P < 0.05). Multivariate analysis indicated that BMI was an independent risk factor for postoperative morbidity (P < 0.05). CONCLUSIONS The MDSG in TLDG is safe and feasible for early GC; however, it should be chosen with caution in advanced GC, particularly in patients with a high BMI.

Abstract
Abstract
Background
Surgical education is becoming competency-based with the implementation of in-training milestones. Training guidelines should reflect these changes and determine the specific procedures for such milestone assessments. This study aimed to develop a consensus view regarding operative procedures and tasks considered appropriate for junior and senior trainees, and the procedures that can be used as technical milestone assessments for trainee progression in general surgery.
Methods
A Delphi process was followed where questionnaires were distributed to all 17 Canadian general surgery programme directors. Items were ranked on a 5-point Likert scale, with consensus defined as Cronbach's α of at least 0·70. Items rated 4 or above on the 5-point Likert scale by 80 per cent of the programme directors were included in the models.
Results
Two Delphi rounds were completed, with 14 programme directors taking part in round one and 11 in round two. The overall consensus was high (Cronbach's α = 0·98). The training model included 101 unique procedures and tasks, 24 specific to junior trainees, 68 specific to senior trainees, and nine appropriate to all. The assessment model included four procedures.
Conclusion
A system of operative procedures and tasks for junior- and senior-level trainees has been developed along with an assessment model for trainee progression. These can be used as milestones in competency-based assessments.

Abstract
Laparoscopic gastrectomy (LG) is a safe alternative compared to open gastrectomy for cancer. To increase the uptake of minimally invasive approaches and facilitate their analysis and improvement a stepwise approach is warranted. This study describes our technique and experiences total laparoscopic gastrectomy (TLG) with jejunal pouch reconstruction for gastric cancer. Technical modifications throughout the years were described. In patients with anastomotic leakage, the CT-scan and reoperation report were reviewed to identify the location and cause of the leak. A total of 47 patients who underwent laparoscopic total gastrectomy with extracorporeal jejunal pouch reconstruction and stapled circular esophagojejunostomy from May 2007 to August 2015 were prospectively analyzed. A stepwise approach of 10 steps was designed based on video and case analysis. Median operation time was 301 (148-454) minutes and median blood loss was 300 (30-900) milliliters. Anastomotic leakage occurred in six (12.8 %) patients; additionally, one (2.12 %) jejunal-pouch staple line leak was identified. An important modification in our technique was a purse-string suture around the anvil of the circular stapler to prevent esophageal mucosa to slip away. After this modification, the leakage rate was reduced to 7 % in the last 15 procedures. In conclusion, TLG with jejunal pouch reconstruction is a feasible procedure in a selected group of patients. Our stepwise approach and technique may help surgeons to introduce jejunal pouch reconstruction during laparoscopic gastrectomy in their center.

Abstract
Purpose Laparoscopic total gastrectomy (LTG) is more complicated than laparoscopic distal gastrectomy, especially during a surgeon's initial experience with the technique. In this study, we evaluated the short-term outcomes of and learning curve for LTG during the initial cases of a single surgeon compared with those of open total gastrectomy (OTG). Materials and Methods Between 2009 and 2013, 134 OTG and 74 LTG procedures were performed by a single surgeon who was experienced with OTG but new to performing LTG. Clinical characteristics, operative parameters, and short-term postoperative outcomes were compared between groups. Results Advanced gastric cancer and D2 lymph node dissection were more common in the OTG than LTG group. Although the operation time was significantly longer for LTG than for OTG (175.7±43.1 minutes vs. 217.5±63.4 minutes), LTG seems to be slightly superior or similar to OTG in terms of postoperative recovery measures. The operation time moving average of 15 cases in the LTG group decreased gradually, and the curve flattened at 54 cases. The postoperative complication rate was similar for the two groups (11.9% vs. 13.5%). No anastomotic or stump leaks occurred. Conclusions Although LTG is technically difficult and operation time is longer for surgeons experienced in open surgery, it can be performed safely, even during a surgeon's early experience with the technique. Considering the benefits of minimally invasive surgery, LTG is recommended for early gastric cancer.

Abstract
BACKGROUND AND OBJECTIVES When performed at select centers, minimally invasive gastrectomy (MIG) for gastric adenocarcinoma is associated with reduced perioperative morbidity, and similar oncologic outcomes as compared to open gastrectomy (OG). Utilization of, and outcomes associated with, MIG in the United States have not been characterized. METHODS The National Cancer Database (2010-2011) was queried for AJCC pStage IB-IIIC patients who underwent curative-intent OG (n = 2,303) or MIG (n = 331). Multivariable models identified factors associated with MIG utilization, R0 resection rates, and adequate lymph node staging (LNS). RESULTS MIG was more frequently utilized for T1/T2 (P < 0.001), N0 (P = 0.022), and stage IB (P = 0.001) tumors. MIG was associated with shorter hospital stay (P < 0.001), equivalent lymph node examination (P = 0.337) and superior rates of R0 resection (P = 0.011) compared with OG. In patients undergoing MIG, R0 resection was associated with performance of near-total/total gastrectomy (OR 3.90, 95%CI 1.10-13.9) and tumors < 5 cm (OR 2.78, 95%CI 1.07-7.26). Adequate LNS was associated with surgery at academic (OR 1.99, 95%CI 1.19-3.32) or high-volume facilities (OR 2.97, 95%CI 1.59-5.54), tumor size ≥ 5 cm (OR 1.85, 95%CI 1.10-3.11), and node positivity (OR 1.75, 95%CI 1.04-2.93). CONCLUSIONS MIG is selectively utilized in cases with favorable tumor characteristics. In such cases, short-term oncologic outcomes are equivalent to those achieved with OG. Worse oncologic outcomes in specific subgroups underscore opportunities for quality improvement.

Abstract
OBJECTIVE To validate the efficacy and safety of laparoscopic total gastrectomy (LTG) for advanced gastric cancer (AGC). BACKGROUND Laparoscopic distal gastrectomy (LDG) in the treatment of patients with local AGC is becoming increasingly popular, and there have been several multicenter randomized controlled trials focused on this treatment. However, few reports on the procedure of LTG for AGC exist. METHODS The data of 976 patients who underwent LTG for AGC were retrieved from a prospectively constructed database of 2170 patients who underwent laparoscopic gastrectomy between 2007 and 2013. Surgical outcomes of LTG were investigated and compared with those of patients who underwent LDG. RESULTS LTG was associated with significantly longer operation time, number of dissected lymph nodes, and time of resume soft diet compared with the LDG group. According to Clavien-Dindo classification, the morbidity and mortality rates of the LTG group were comparable to those of the LDG group. Multivariate analyses revealed that elderly patients, more comorbidities, and longer operation time were the significant independent risk factors for determining postoperative complications. The difference in overall survival rates between the two groups was statistically significant. However, a comparative analysis of overall survival showed no statistical significance for any of the stages of cancer between the LTG and LDG groups. CONCLUSIONS The study findings suggest that LTG is an oncologically safe procedure for AGC yields comparable surgical outcomes. A well-designed phase III trial can be carried out to provide valuable evidence for the oncologic safety of LTG for the treatment of AGC.

Abstract
To investigate the risk factors for postoperative complications following laparoscopic gastrectomy (LG) for gastric cancer and to use the risk factors to develop a predictive scoring system.Few studies have been designed to develop scoring systems to predict complications after LG for gastric cancer.We analyzed records of 2170 patients who underwent a LG for gastric cancer. A logistic regression model was used to identify the determinant variables and develop a predictive score.There were 2170 patients, of whom 299 (13.8%) developed overall complications and 78 (3.6%) developed major complications. A multivariate analysis showed the following adverse risk factors for overall complications: age ≥65 years, body mass index (BMI) ≥ 28 kg/m, tumor with pyloric obstruction, tumor with bleeding, and intraoperative blood loss ≥75 mL; age ≥65 years, a Charlson comorbidity score ≥3, tumor with bleeding and intraoperative blood loss ≥75 mL were identified as independent risk factors for major complications. Based on these factors, the authors developed the following predictive score: low risk (no risk factors), intermediate risk (1 risk factor), and high risk (≥2 risk factors). The overall complication rates were 8.3%, 15.6%, and 29.9% for the low-, intermediate-, and high-risk categories, respectively (P < 0.001); the major complication rates in the 3 respective groups were 1.2%, 4.7%, and 10.0% (P < 0.001).This simple scoring system could accurately predict the risk of postoperative complications after LG for gastric cancer. The score might be helpful in the selection of risk-adapted interventions to improve surgical safety.

Abstract
BACKGROUND EUS is an operator-dependent procedure and requires more technical and cognitive skills than a routine endoscopic procedure. The learning curve for the staging of gastric cancer, however, has not been evaluated. OBJECTIVE To evaluate the threshold number of EUS examinations for gastric cancer T staging. DESIGN Retrospective study. SETTING University-affiliated tertiary care hospital in the Republic of Korea. PATIENTS Four trainees with no previous EUS experience. INTERVENTION Analyzing performance of EUS trainees in gastric cancer T staging by using cumulative sum (CUSUM) analysis. MAIN OUTCOME MEASUREMENTS CUSUM plot and a minimal number of procedures for reaching a plateau. RESULTS A total of 553 initial EUS examinations for treatment-naïve gastric cancers, performed by trainees, were enrolled in the study. The final T stage was determined by experts by using EUS in 332 gastric cancer cases, whereas the T stage of the other 221 lesions was determined by trainees by using EUS. The accuracy of EUS examinations performed by trainees and experts was 72.6% and 84.3%, respectively. The number of EUS examinations required to reach the first plateau in each trainee was 20, 41, 60, and 65. LIMITATIONS Retrospective study with a relatively small number of trainees. CONCLUSION The CUSUM scores of all of 4 trainees in the study reached a plateau by the 65th examination.
