Abstract
BACKGROUND Radical gastrectomy followed by adjuvant chemotherapy is the standard treatment for stage II or III gastric cancer in Asian countries. Early recurrence during or after adjuvant chemotherapy is associated with poor prognosis; however, risk factors for early recurrence remain unclear. METHODS In this multicenter, retrospective cohort study including six institutions, we evaluated the clinicopathological factors of 553 patients with gastric cancer undergoing gastrectomy followed by adjuvant chemotherapy between 2012 and 2016. Patients were divided into the following groups: early recurrence (recurrence during adjuvant chemotherapy or within 6 months after adjuvant chemotherapy completion) and non-early recurrence, which was further divided into late recurrence and no recurrence. Early-recurrence risk factors were investigated using multivariate Cox proportional hazard model. The chronological changes in the recurrence hazard were also examined for each factor. RESULTS Early recurrence and late recurrence occurred in 83 (15.0%) and 73 (13.2%) patients, respectively. Based on the Cox proportional hazards model, a postoperative serum carcinoembryonic antigen level of ≥5 ng/mL (hazard ratio: 2.220, 95% confidence interval: 1.089-4.526) and a neutrophil-to-lymphocyte ratio of >1.8 (hazard ratio: 2.408, 95% confidence interval: 1.479-3.92) were identified as independent risk factors of early recurrence, but not late recurrence. The recurrence hazard ratios for neutrophil-to-lymphocyte ratio significantly decreased over time (P < 0.001) and carcinoembryonic antigen also had the same tendency (P = 0.08). CONCLUSIONS A carcinoembryonic antigen level of ≥5 ng/mL and a neutrophil-to-lymphocyte ratio of >1.8 are predictors of early recurrence after radical gastrectomy and adjuvant chemotherapy for stage II or III gastric cancer.

Abstract
Wound infection and tumor recurrence are the two main threats to cancer patients after surgery. Although researchers have developed new treatment systems to address the two significant challenges simultaneously, the potential side effects of the heavy-metal-ion-based treatment systems still severely limit their widespread application in therapy. In addition, the wounds from tumor removal compared with general operative wounds are more complex. The tumor wounds mainly exhibit more hemorrhage, larger trauma area, greater vulnerability to bacterial infection, and residual tumor cells. Therefore, a multifunctional treatment platform is urgently needed to integrate rapid hemostasis, sterilization, wound healing promotion, and antitumor functions. In this work, nanodiamonds (NDs), a material that has been well proven to have excellent biocompatibility, are added into a solution of acrylic-grafted chitosan (CEC) and oxidized hyaluronic acid (OHA) to construct a multifunctional treatment platform (CEC-OHA-NDs). The hydrogels exhibit rapid hemostasis, a wound-healing-promoting effect, excellent self-healing, and injectable abilities. Moreover, CEC-OHA-NDs can effectively eliminate bacteria and inhibit tumor proliferation by the warm photothermal effect of NDs under tissue-penetrable near-infrared laser irradiation (NIR) without cytotoxicity. Consequently, we adopt a simple and convenient strategy to construct a multifunctional treatment platform using carbon-based nanomaterials with excellent biocompatibility to promote the healing of infected wounds and to inhibit tumor cell proliferation simultaneously.

Abstract
PURPOSE One-year mortality is important for referrals to specialist palliative care or advance care planning (ACP). This helps optimize comfort for those who cannot be cured or have a lower life expectancy. Few studies have investigated the risk factors for 1-year mortality after gastrectomy for gastric cancer (GC). METHODS A total of 1415 patients with gastric cancer (stages I-IV) who underwent gastrectomy between 2005 and 2020 were included. The patients were randomly assigned to the investigation group (n = 850) and validation group (n = 565) in a 3:2 ratio. In the investigation group, significant independent prognostic factors for predicting 1-year survival were identified. A scoring system for predicting 1-year mortality was developed which was validated in the validation group. RESULTS Multivariate analysis revealed that the following seven variables were significant independent factors for 1-year survival: age ≧78, preoperative comorbidity, total gastrectomy, postoperative complication (Clavien-Dindo classification CD ≧ 3a), stage III and IV, and R2 resection. While developing a 1-year mortality score (OMS), an age ≧78 was scored 2, preoperative comorbidity, total gastrectomy, and postoperative complication (CD ≧ 3a) were scored 1, and stage III, IV, and R2-resection were scored 2, 3, and 3, respectively. OMS 3 had a sensitivity of 91% and a specificity of 66% for predicting death within 1 year. In the validation group, OMS 5 had a sensitivity of 55% and a specificity of 93% for predicting death within 1 year. CONCLUSIONS OMS may provide important information and help surgeons select the timing of ACP in patients with GC.

Abstract
Background: Postoperative gastrointestinal fistula (PGF) is one of the main causes of abdominal infection and perioperative death. This study was designed to investigate the risk factors of PGF, anastomotic fistula (AF), and duodenal stump fistula (DSF) for patients who underwent radical distal gastrectomy. Materials and Methods: In this retrospective observational study, 2652 gastric cancer cases who received radical distal gastrectomy from 2010 to 2020 were selected as research subjects. Subsequently, we adopted the univariate and multivariate logistic regression analysis as statistical method to screen the risk factors for PGF, AF, and DSF, respectively. Results: In univariate analysis, gender (P = .022), operative time (P = .013), intraoperative blood loss (P < .001), tumor diameter (P = .002), and tumor stage (P < .001) were related to PGF. Multivariate logistic regression analysis identified the male (odds ratio [OR] = 2.691, P = .042), massive intraoperative hemorrhage (OR = 1.002, P = .008), and advanced tumor (OR = 2.522, P = .019) as independent predictors for PGF. Moreover, diabetes (OR = 4.497, P = .008) and massive intraoperative hemorrhage (OR = 1.003, P = .010) were proved to be associated with AF, while massive intraoperative hemorrhage (OR = 1.001, P = .050) and advanced tumor (OR = 6.485, P = .005) were independent risk factors of DSF. Conclusions: The gender, intraoperative hemorrhage, tumor stage, and diabetes were expected to be used as predictors of PGF for radical distal gastrectomy.

Abstract
BACKGROUND Gastrectomy with lymphadenectomy in combination with perioperative chemotherapy is the cornerstone of modern curative treatment for gastric adenocarcinoma. The primary objective of this study was to assess the influence of textbook outcome, postoperative complications, and readmission on survival in patients who underwent gastric cancer surgery. METHODS Consecutive patients who underwent curative and prophylactic gastric resections from 2014 to 2022 at Christchurch Hospital were identified from the hospital database. Multivariable analyses were performed to assess risk factors for each postoperative outcome. A survival analysis was performed to evaluate the influence of these outcomes on overall survival. RESULTS Seventy-seven patients underwent a gastric resection during the study period. Thirteen were prophylactic resections for E-cadherin gene mutations and 64 were for malignancy. The overall postoperative complication rate was 34%, with an anastomotic leak rate of 8% (n = 6). The 30-day readmission rate, 30-day mortality rate and 90-day mortality rate were 17%, 1%, and 5% respectively. No sociodemographic differences were identified in each outcome. An increasing day-4 CRP trajectory was observed in patients with an anastomotic leak. Postoperative complications and nodal disease were independent prognostic factors for reduced survival. CONCLUSIONS Textbook outcome, postoperative complications, and readmission are validated quality performance indicators of gastric cancer surgery. Postoperative complications are associated with poor overall survival independent of severity or type. The underlying mechanisms of this influence remain elusive. The aggressive biology of gastric cancer, combined with the surgical morbidity and its negative influence on survival, highlights the importance of ongoing quality improvement.

Abstract
BACKGROUND The long-term survival of postoperative anastomotic leakage (AL) following gastric cancer (GC) surgery is still debating. Our aim was to investigate the association between AL and survival of the patients following GC. METHODS We searched articles in databases from inception to July 2023 to retrieve literature related to postoperative AL and survival of GC patients. We evaluated the association of postoperative AL and survival of GC patients using the software STAT10.0. RESULTS Seven articles with 6209 GC patients were included. Our results showed that the postoperative AL were associated with pooled 1-year patient overall survival (OS) result in an odds ratio (OR) of 0.504 (95% confidence interval (CI): 0.372-0.682; I2 = 84.1%; P = .000), pooled 3-year patient OS (OR = 0.467, 95% CI: 0.356-0.614; I2 = 85.3%; P = .000) and pooled 5-year patient OS (OR = 0.370, 95% CI: 0.171-0.805; I2 = 82.5%; P = .012). The P value of Egger test were 0.759, 0.187, 0.175. The postoperative AL were associated with pooled 1-year patient disease-free survival (DFS) result in an OR of 0.538 (95% CI: 0.171-1.691; I2 = 89.0%; P = .289), the pooled 3-year patient DFS (OR = 0.143, 95% CI: 0.119-1.431; I2 = 91.7%; P = .163), and the pooled 5-year patient DFS (OR = 0.344, 95% CI: 0.088-1.338; I2 = 91.0%; P = .124), and the P value of Egger test of pooled 1-, 3-, and 5-year DFS were 0.759, 0.247, 0.07. CONCLUSION Postoperative AL was correlated with a worse OS in GC patients, but not correlated with DFS in GC patients, but more studies are required to confirm this conclusion.

Abstract
BACKGROUND Anastomotic leakage following a radical gastrectomy is a serious complication of gastric cancer and esophagogastric junction cancer. The benefit of intraoperative leak testing for the prevention of postoperative anastomotic leakage has been controversial. We introduce a new procedure, which combines the techniques of gastroscopy, air, and methylene blue (GAM) for intraoperative leakage testing. Our objective was to evaluate the efficacy and safety of the GAM procedure for intraoperative leak testing and to compare the surgical complications of gastric cancer patients who underwent gastrectomy with and without intraoperative leak testing using the GAM procedure. MATERIALS AND METHODS A total of 210 patients who underwent radical gastrectomy for gastric cancer were included. Patients were divided into 2 groups: the intraoperative leak testing group using the GAM procedure (IOLT), and the group for which no intraoperative leak testing was done (NIOLT). Clinical and pathologic characteristics, the incidence of postoperative anastomotic leakage, and other surgical complications were compared between the 2 groups. RESULTS There were 82 patients in the IOLT group and 82 patients in the NIOLT group after propensity score matching. In the IOLT group, 4 (4.9%) patients were found to have anastomotic discontinuity during the operation; we repaired these anastomotic discontinuities intraoperatively. The incidence of postoperative anastomotic leakage was higher in the NIOLT group compared with the IOLT group, 6 (7.3%) versus 0 (0%), respectively ( P =0.01). The average time of the GAM procedure was 4.99±1.75 minutes. The surgical time was prolonged by 30 minutes in the IOLT group compared with the NIOLT group, 302.2±79.9 versus 272.1±85.2, respectively ( P =0.02). The length of hospital stay, 15.80±4.55 versus 17.00±6.20 ( P =0.16) was reduced in the IOLT group compared with the NIOLT group. The logistic regression model suggested that IOLT, sex, age, Eastern Cooperative Oncology Group, cT stage, tumor diameter, pT stage, pN stage, and Lauren classification were not risk factors for postoperative complication. CONCLUSIONS The GAM procedure of intraoperative leakage testing can effectively reduce the incidence of postoperative anastomotic leakage in gastric cancer patients undergoing gastrectomy.

Abstract
Background In two facilities in Chongqing, this research sought to retrospectively evaluate the effects of perineal wound infection on survival after laparoscopic abdominoperineal resection (LAPR) of rectal cancer. Methods To obtain clinical information on patients who underwent LAPR between January 2013 and December 2021, we performed a multicenter cohort study. A total of 473 patients were enrolled: 314 in the non-infection group and 159 in the group with perineal infection. The general data, perioperative conditions, and tumor outcomes between groups were analyzed. The infection rates, recurrence rates, and survival rates of the two centers were compared. Results The age, height, weight, body mass index (BMI), preoperative complications, preoperative treatment, and intraoperative conditions of patients in the LAPR infection group were not statistically different from those in the non-infection group. The percentage of men, typical postoperative hospital stay, length of initial postoperative therapy, and recurrence and metastasis rates were all considerably higher in the infection group than those in the non-infection group. Wound infection was an independent factor affecting tumor recurrence and metastasis after LAPR as well as an independent factor shortening patient survival time according to multivariate analysis. The incidence of wound infection, the rate of recurrence, and the rate of mortality did not vary significantly across sites. Conclusion Wound infection after LAPR increases the mean postoperative hospital stay, prolongs the time to first postoperative treatment, and decreases the disease-free survival (DFS) and overall survival (OS). Therefore, decreasing the rate of LAPR wound infection is expected to shorten the postoperative hospital stay and prolong the patient DFS and OS. Patients with postoperative infection may require intensive adjuvant therapy.

Abstract
We performed a meta-analysis to evaluate the oncological results in women with wound complications following mastectomy and immediate breast reconstruction. A systematic literature search up to August 2022 was performed and 1618 subjects with mastectomy and immediate breast reconstruction at the baseline of the studies; 443 of them were with wound complications, and 1175 were with no wound complications as a control. Odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CIs) were calculated to assess the oncological results in women with wound complications following mastectomy and immediate breast reconstruction using dichotomous or contentious methods with a random or fixed-effect model. The wound complications had a significantly longer length of time to adjuvant therapy (MD, 9.44; 95% CI, 4.07-14.82, P < .001) compared with no wound complications in subjects with mastectomy and immediate breast reconstruction. However, no significant difference was found between wound complications and no wound complications in subjects with mastectomy and immediate breast reconstruction in breast cancer recurrence (OR, 1.96; 95% CI, 0.95-4.06, P = .07), death rates (OR, 1.95; 95% CI, 0.89-4.27, P = .09), and kind of immediate breast reconstruction (OR, 1.01; 95% CI, 0.53-1.92, P = .98). The wound complications had a significantly longer length of time to adjuvant, however, no significant difference was found in breast cancer recurrence, death rates, and kind of immediate breast reconstruction. The analysis of outcomes should be done with caution even though no low sample size was found in the meta-analysis but a low number of studies was found in certain comparisons.

Abstract
Background Near-infrared fluorescence image-guided surgery helps surgeons to see beyond the classical eye vision. Over the last few years, we have witnessed a revolution which has begun in the field of image-guided surgery. Purpose, and Research design Fluorescence technology using indocyanine green (ICG) has shown promising results in many organs, and in this review article, we wanted to discuss the 6 main domains where fluorescence image-guided surgery is currently used for esophageal and gastric cancer surgery. Study sample and data collection Visualization of lymphatic vessels, tumor localization, fluorescence angiography for anastomotic evaluation, thoracic duct visualization, tracheal blood flow analysis, and sentinel node biopsy are discussed. Conclusions It seems that this technology has already found its place in surgery. However, new possibilities and research avenues in this area will probably make it even more important in the near future.

Abstract
INTRODUCTION The pancreas often interferes with the surgical field during laparoscopic gastrectomy (LG) and its disorders cause severe postoperative complications. This study aimed to evaluate the association between the anatomical location of the pancreas and surgical outcome and to investigate the optimal surgical position in LG. METHODS We newly defined the angle formed between the supra-pancreatic region and the root of the left gastric artery (LGA) as the pancreas-LGA angle (PLA). The association between PLA and surgical outcomes in 107 consecutive patients who underwent laparoscopic distal gastrectomy (LDG) was investigated. Then, the change in PLA before and after insertion of the back pillow in 30 patients with gastric cancer was examined. RESULTS The median PLA was 62° (range, 2°-157°). No differences were found in the patient background between patients with small PLA (PLA < 62°; n = 53) and those with large PLA (PLA ≧ 62°; n = 54). The postoperative inflammation response (white blood cells, neutrophils, and C-reactive protein) and amylase concentration in the drainage fluid (D-AMY) were significantly higher in the small PLA group than large PLA group. Multivariable analyses demonstrated that small PLA was an independent risk factor for high D-AMY. After insertion of a back pillow, PLA was noninvasively increased in all patients, and the median PLA was changed to 92° (range, 8°-151°) from 61° (range, 2°-140°). Of 17 patients with small PLA, nine developed large PLA. CONCLUSIONS These results suggest that PLA can become one of the indicators of postoperative complications related to anatomical patient factors in LDG.

Abstract
PURPOSE The application of laparoscopic-assisted total gastrectomy (LATG) for resectable gastric cancer (GC) remains controversial compared with open total gastrectomy (OTG), especially for advanced gastric cancer (AGC) patients according to the inconsistent results demonstrated in the previous studies. The aim of this study was to evaluate the short-term and long-term outcomes between LATG and OTG in a population with more than 80% AGC patients by applying propensity score matching (PSM) method. METHODS The data of 365 clinical stage I-III GC cases who underwent total gastrectomy with D2 lymphadenectomy were retrospectively collected from January 2011 to April 2018 in the Department of Gastrointestinal Surgery IV of Peking University Cancer Hospital. Propensity scores were generated through taking all covariates into consideration and 131 pairs of patients receiving either LATG or OTG were matched. Intraoperative, postoperative, and survival parameters were compared in the matched groups accordingly. Risk factors for postoperative complications and overall survival were further analyzed. RESULTS Patient characteristics in the LATG and OTG groups were well balanced after PSM. LATG showed advantages with respect to shorter time to ambulation, first flatus, and first whole liquid diet intake. No significant differences were found between the two groups with regard to postoperative complications as well as overall survival in terms of different pathological stage. Older age was found as an independent risk factor for postoperative complications, and pathological stage for overall survival as well. CONCLUSION LATG appears to have comparable surgical and oncological safety with OTG by experienced surgeons.

Abstract
PURPOSE This study aimed to clarify the relationship between obesity and postoperative C-reactive protein (CRP) and assess the usefulness of obesity status-adjusted CRP levels for predicting early complications following laparoscopic gastrectomy for gastric cancer. METHODS This study retrospectively analyzed 527 patients who underwent laparoscopic gastrectomy for gastric cancer between January 2013 and March 2019. Patients were classified into three groups according to body mass index (BMI): BMI < 20; BMI ≥ 20 to < 25; and BMI ≥ 25. The correlation between BMI and perioperative CRP was investigated in 447 patients, excluding 80 with postoperative complications. The optimal CRP cutoff value of Clavien-Dindo (CD) grade ≥ 3 for predicting severe complications for each group was determined. RESULTS BMI was significantly correlated with CRP on postoperative day (POD) 3 (p < 0.001) in 447 patients without complications. According to the receiver operating characteristic curve analysis, CRP cutoff values on POD 3 for predicting severe complications were 92.4, 111.1, and 171.9 in the BMI < 20, BMI ≥ 20 to < 25, and BMI ≥ 25 groups, respectively. In multivariate analysis for CD grade ≥ 3 complications, cardiac history and POD 3 CRP levels higher than the adjusted cutoff were identified as independent factors significantly associated with severe complications (p = 0.021 and 0.015, respectively). CONCLUSION CRP cutoff values on POD 3 adjusted for BMI were useful for predicting severe complications in gastrectomy for gastric cancer.

Abstract
Background: Whether the presence of postoperative complications was associated with poor prognosis of gastric carcinoma (GC) patients remain controversial. This meta-analysis was designed and reported to compare the survival difference between patients with complications and non-complications. Methods: Cochrane Library, PubMed and Embase databases were comprehensively searched for published literatures to review current evidence on this topic. The survival data were extracted, and a random-effect or fixed-effect model was used to analyze the correlation between postoperative complications and oncologic outcome of GC patients. Results: Of all studies identified, 32 were eligible for this pooled analysis, with a total of 32,067 GC patients. The incidence of postoperative complications was approximately 12.5% to 51.0%. Among them, infectious complications varied from 3.0% to 28.6%, anastomotic leakage varied from 1.1% to 8.7% and postoperative pneumonia varied from 1.6% to 12.8%. The presence of postoperative complications resulted in a significant poorer overall survival (OS) of gastric carcinoma patients (hazard ratio [HR]:1.49, 95% confidence interval [CI]: 1.33-1.67, P < 0.001). Additionally, the pooled results showed a significant correlation between infectious complications and decreased OS (HR: 1.61, 95%CI: 1.38-1.88, P < 0.001). Concerning specific postoperative complications, we found that both anastomotic leakage (HR: 2.36, 95%CI: 1.62-3.42, P < 0.001) and postoperative pneumonia (HR: 1.74, 95%CI: 1.22-2.49, P = 0.002) impaired the OS of gastric carcinoma patients. Conclusion: Postoperative complications were significantly correlated to recurrence and poor survival in gastric carcinoma patients. To gain a better surgical outcome and long-term oncological outcome, postoperative complications should be minimized as much as possible.

Abstract
Background Postoperative complications have been linked to the morbidity and mortality of several cancers. However, predicting whether complications will occur in the early period after surgery or not is challenging. Hence, this study aimed to examine the diagnostic accuracy of serum creatine phosphokinase (CPK) and c-reactive protein (CRP) in predicting the development of postgastrectomy complications. Methods We retrospectively analyzed 188 patients with gastric cancer (GC) who underwent gastrectomy. The diagnostic accuracy of serum CPK and CRP was investigated using the areas under the curves (AUC). The CPK ratio was defined as the CPK on postoperative day (POD) 1 to the CPK on a preoperative day. Results Out of 188 patients, 48 (25.5%) developed postoperative complications. The complications group had a greater operative time (p = 0.037), higher CPK ratio on POD1 (p < 0.0001), and a higher serum CRP level on POD3 (p = 0.001). The AUC for the CPK ratio was 0.772, with an optimal cutoff value of 7.05, whereas that for CRP was 0.659, with an optimal cutoff value of 11.4 mg/L. The CPK ratio on POD1 (p < 0.0001) and the CRP on POD3 (p = 0.007) were independent factors for predicting the development of postgastrectomy complications. The CPK ratio on POD1 and the CRP on POD3 predicted postgastrectomy complications in 41 patients (85.4%). According to combined value of both CPK ratio and CRP level, the positive predictive value and the negative predictive value was 0.70 and 0.829. And sensitivity and specificity were 0.438 and 0.936. Conclusion The CPK ratio on POD1 and the CRP on POD3 after gastrectomy for GC were predictive factors for complication development and may be employed to prevent the development of such complications and improve the prognosis of patients with GC.

Abstract
Purpose Minimally invasive gastrectomy is a promising surgical method with well-known benefits, including reduced postoperative complications. However, for total gastrectomy of gastric cancers, this approach does not significantly reduce the risk of complications. Therefore, we aimed to evaluate the incidence and risk factors for the severity of complications associated with minimally invasive total gastrectomy for gastric cancer. Materials and Methods The study included 392 consecutive patients with gastric cancer who underwent either laparoscopic or robotic total gastrectomy between 2011 and 2019. Clinicopathological and operative characteristics were assessed to determine the features related to postoperative complications after minimally invasive total gastrectomy. Binomial and multinomial logistic regression models were used to identify the risk factors for overall complications and mild and severe complications, respectively. Results Of 103 (26.3%) patients experiencing complications, 66 (16.8%) and 37 (9.4%) developed mild and severe complications, respectively. On multivariate multinomial regression analysis, independent predictors of severe complications included obesity (OR, 2.56; 95% CI, 1.02−6.43; P=0.046), advanced stage (OR, 2.90; 95% CI, 1.13−7.43; P=0.026), and more intraoperative bleeding (OR, 1.04; 95% CI, 1.02−1.06; P=0.001). Operation time was the only independent risk factor for mild complications (OR, 1.06; 95% CI, 1.001−1.13; P=0.047). Conclusions The risk factors for mild and severe complications were associated with surgery, indicating surgical difficulty. Surgeons should be aware of these potential risks that are related to the severity of complications so as to reduce surgery-related complications after minimally invasive total gastrectomy for gastric cancer.

Abstract
The association between immediate breast reconstruction (IBR)-related wound complications and breast cancer recurrence (BCR) remains uncertain. This study aimed to investigate the oncological outcomes in patients with wound complications following mastectomy and IBR. A comprehensive search was undertaken for all studies describing complications in patients with breast cancer following IBR. Studies were included if they reported on complications and investigated their relationship with BCR. A meta-analysis was performed using a random-effects model, with data presented as odds ratios and 95% confidence intervals. A total of 1418 patients from five studies were included in the final analysis. The mean age of patients included was 47.2 years. A total of 382 (26.9%) patients had postoperative complications following a majority of implant-based IBR (929/1418). A total of 158 (11.1%) recurrences, which included 63 locoregional and 106 distant recurrences, was noted at a mean follow-up of 66 months. Although there was an increase in recurrence rates in the complication group (n = 66/382; 17.3% vs. n = 92/1036; 8.9%), there was no significant association between complications and BCR (17.3% vs. 8.9%; P = .18) or mortality (3.6% vs. 2.3%; P = .15). Time to adjuvant therapy was significantly increased in patients with complications (mean difference, 8.69 days; range, 1.18-16.21 days; P = .02; I2 = 0.02). This meta-analysis demonstrated a higher incidence of wound complications following IBR and a statistically significant increased time to adjuvant therapy. However, this did not translate into adverse oncological outcomes in patients with breast cancer undergoing IBR.

Abstract
Objective: To compare the short-term clinical effects between totally laparoscopic radical gastrectomy with modified Roux-en-Y anastomosis, and laparoscopic-assisted radical gastrectomy with Roux-en-Y anastomosis; to explore the safety, feasibility and short-term effect of totally laparoscopic radical gastrectomy with modified Roux-en-Y anastomosis. Methods: Data of 75 patients who underwent totally laparoscopic radical gastrectomy with modified Roux-en-Y anastomosis, and 95 patients who underwent laparoscopic-assisted radical gastrectomy with Roux-en-Y anastomosis by the same surgical team were analyzed. During the modified Roux-en-Y anastomosis, the stomach separation and regional lymph node dissection were completed under a laparoscope; the specimen was placed in a bag; gastrojejunostomy was completed; the subumbilicus hole was enlarged to 3 cm; the specimen was taken out; then, the proximal and distal ends of the small intestine were moved outside of the abdominal wall to complete the small intestine-small intestine end-to-side anastomosis. Results: All 170 operations were successful. The differences in the time of anastomosis and the number of dissected lymph nodes between the 2 groups were not statistically significant (P > 0.05), but in the totally-MA group the amount of bleeding and the length of incision significantly decreased (P < 0.05). The recovery time as measured by breathing unassisted, drinking fluids and getting out of bed was significantly shorter than those in the laparoscopic-assisted group (P < 0.05), and the pain score 1 day after surgery was significantly lower than that of the laparoscopic-assisted group (P < 0.05). One case of duodenal stump leakage and 1 case of esophagojejunostomy leakage were found in the laparoscopic-assisted group. In the totally-MA group, there were no complications such as anastomotic leakage, anastomotic stenosis or anastomotic bleeding, but 2 patients with double primary carcinoma underwent joint radical resection. Conclusion: Compared with laparoscopic-assisted surgery, totally laparoscopic radical gastrectomy with modified Roux-en-Y anastomosis has the advantages of being safer and less traumatic, with associated reductions in bleeding and pain.

Impact of postoperative complications on long-term outcomes of patients following surgery for gastric cancer: A systematic review and meta-analysis of 64 follow-up studies. Asian J Surg 2020; 43:719-729. [PMID: 31703889 DOI: 10.1016/j.asjsur.2019.10.007] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2019] [Revised: 10/11/2019] [Accepted: 10/16/2019] [Indexed: 12/14/2022] Open
Abstract
Gastrectomy for cancer is a technically demanding procedure, with postoperative complications (POCs) reported to be in the range of 20%-46%. However, the effect of POCs on long-term survival of gastric cancer patients following surgery is far from conclusive. This systemic review aimed to determine the impact of postoperative complications (POCs) on the long-term survival of patients following surgery for gastric cancer. A systematic electronic search of PubMed and Scopus was performed from inception to June 26, 2018 to identify studies that described the relationship between POCs and long-term survival. Hazard ratios (HRs) for overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) from each study were combined using a random-effects model. Sixty-four eligible studies with reported results for 46198 gastric cancer patients were included. A meta-analysis found a statistically significant difference in OS, CSS and RFS between gastric patients with unspecific POCs and no POCs, POCs ≥ Clavien-Dindo grade (CD) 2 and < CD2, major POCs and minor POCs, infectious and non-infectious complications, anastomotic and non-anastomotic complications, and cardiopulmonary and non-cardiopulmonary complications. Subgroup and sensitivity analyses did not significantly change the summary of OS risk estimates between patients with POCs and without POCs. No significant publication bias was observed for the same outcome. The meta-analysis revealed that POCs were associated with worse survival among patients with resected gastric cancer, suggesting that treatment strategies aimed at minimizing POCs may improve oncological outcomes.

Laparoscopic sentinel node navigation surgery versus laparoscopic gastrectomy with lymph node dissection for early gastric cancer: short-term outcomes of a multicentre randomized controlled trial (SENORITA). Br J Surg 2020; 107:1429-1439. [PMID: 32492186 DOI: 10.1002/bjs.11655] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Revised: 03/05/2020] [Accepted: 04/06/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND Sentinel node navigation surgery reduces the extent of gastric and lymph node dissection, and may improve quality of life. The benefit and harm of laparoscopic sentinel node navigation surgery (LSNNS) for early gastric cancer is unknown. The SENORITA (SEntinel Node ORIented Tailored Approach) trial investigated the pathological and surgical outcomes of LSNNS compared with laparoscopic standard gastrectomy (LSG) with lymph node dissection. METHODS The SENORITA trial was an investigator-initiated, open-label, parallel-assigned, non-inferiority, multicentre RCT conducted in Korea. The primary endpoint was 3-year disease-free survival. The secondary endpoints, morbidity and mortality within 30 days of surgery, are reported in the present study. RESULTS A total of 580 patients were randomized to LSG (292) or LSNNS (288). Surgery was undertaken in 527 patients (LSG 269, LSNNS 258). LSNNS could be performed according to the protocol in 245 of 258 patients, and a sentinel node basin was detected in 237 (96·7 per cent) Stomach-preserving surgery was carried out in 210 of 258 patients (81·4 per cent). Postoperative complications occurred in 51 patients in the LSG group (19·0 per cent) and 40 (15·5 per cent) in the LSNNS group (P = 0·294). Complications with a Clavien-Dindo grade of III or higher occurred in 16 (5·9 per cent) and 13 (5·0 per cent) patients in the LSG and LSNNS groups respectively (P = 0·647). CONCLUSION The rate and severity of complications following LSNNS for early gastric cancer are comparable to those after LSG with lymph node dissection. Registration number: NCT01804998 ( http://www.clinicaltrials.gov).

Effect of Standardizing the Incision Line on Delayed Gastric Emptying After Laparoscopic Gastrectomy: A Retrospective Preliminary Analysis. Int Surg 2020. [DOI: 10.9738/intsurg-d-16-00062.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
Background
The use of totally laparoscopic surgery with Billroth-I reconstruction (delta-shaped anastomosis) has rapidly become widespread in recent years. However, we experienced delayed gastric emptying (DGE) in the early period after introduction of this technique. To the best of our knowledge, there are no reports that mention the incision line when discussion prevention of DGE in distal gastrectomy. In the present study, we standardized the surgical techniques, including the gastric incision line, and compared the short-term results before and after standardization.
Methods
A total of 86 patients were enrolled in this study. Twenty-eight procedures were performed in the early period, 58 procedures were performed in the late period, and the 2 groups were compared retrospectively.
Results
The operation time decreased significantly after standardization from 288 to 224 minutes (P < 0.001). The median value of perioperative bleeding volume decreased from 22.5 to 12.5 mL (P = 0.060). There were no postoperative complications related to the site of anastomosis in either group. Five cases of DGE (17.8%) were noted in the early period, but only 2 cases (3.4%) were noted in the late period (P = 0.022).
Conclusions
Standardization of the incision line after laparoscopic gastrectomy resulted in a decrease in the incidence of DGE.

Abstract
Abstract
Background
Immediate breast reconstruction is safe from an oncological perspective, but the relatively high rate of postoperative complications raises oncological concerns. The present study aimed to evaluate the potential influence of postoperative complications after immediate breast reconstruction on breast cancer recurrence and survival.
Methods
Patients with breast cancer who had total mastectomy and immediate reconstruction between 2008 and 2013 were followed for at least 5 years. The impact of postoperative complications on oncological outcomes was assessed using multivariable Cox regression analyses.
Results
In total, 438 patients with a median follow-up of 82 months were analysed. Five-year local recurrence-free, disease-free and overall survival rates were 95·4, 93·1 and 98·4 per cent respectively. Postoperative complications developed in the operated breast in 120 patients (27·4 per cent) and at other sites (flap donor) in 30 patients (6·8 per cent). Development of breast complications was associated with significantly increased rate of recurrence compared with no complications (16·7 versus 5·9 per cent; P = 0·002). In multivariable analysis, patients with breast complications had significantly worse disease-free survival than those with no complications (hazard ratio (HR) 2·25; P = 0·015). This remained significant in patients who received adjuvant therapy without delay (8 weeks or less after surgery) (HR 2·45; P = 0·034).
Conclusion
Development of postoperative complications in the breast can have a negative impact on survival and recurrence after immediate reconstruction.

Role of Postoperative Complications in Overall Survival after Radical Resection for Gastric Cancer: A Retrospective Single-Center Analysis of 1107 Patients. Cancers (Basel) 2019; 11:cancers11121890. [PMID: 31783704 PMCID: PMC6966624 DOI: 10.3390/cancers11121890] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2019] [Revised: 11/21/2019] [Accepted: 11/25/2019] [Indexed: 12/16/2022] Open
Abstract
Background: The aim of this study was to investigate the impact of postoperative complications on overall survival (OS) after radical resection for gastric cancer. Methods: A retrospective analysis of our institutional database for surgical patients with gastroesophageal malignancies was performed. All consecutive patients who underwent R0 resection for M0 gastric cancer between October 1972 and February 2014 were included. The impact of postoperative complications on OS was evaluated in the entire cohort and in a subgroup after exclusion of 30 day and in-hospital mortality. Results: A total of 1107 patients were included. In the entire cohort, both overall complications (p < 0.001) and major surgical complications (p = 0.003) were significant risk factors for decreased OS in univariable analysis. In multivariable analysis, overall complications were an independent risk factor for decreased OS (p < 0.001). After exclusion of patients with complication-related 30 day and in-hospital mortality, neither major surgical (p = 0.832) nor overall complications (p = 0.198) were significantly associated with decreased OS. Conclusion: In this study, postoperative complications influenced OS due to complication-related early postoperative deaths. In patients successfully rescued from early postoperative complications, neither overall complications nor major surgical complications were risk factors for decreased survival.

Abstract
BACKGROUND Uncut Roux-en-Y gastrojejunostomy (uRYGJ) was developed to prevent slow peristalsis in the Roux limb after Roux-en-Y gastrojejunostomy (RYGJ). This study compared the incidence of Roux stasis syndrome (RSS) and severe gastric food stasis in gastric cancer patients who underwent RYGJ or uRYGJ after laparoscopic curative distal gastrectomy. METHODS Between January 2006 and June 2012, 319 patients underwent RYGJ or uRYGJ. After covariates were adjusted by propensity score matching, 39 patients in the RYGJ group and 65 patients in the uRYGJ group were included in the final analysis. RSS was defined as the presence of symptoms, such as nausea, vomiting, and abdominal fullness, requiring refasting without ileus or obstruction within 30 days post-surgery. Gastric food stasis was measured endoscopically at 1 and 3 years after gastrectomy. RESULTS Operative outcomes and morbidities were similar between the two groups, whereas the incidence of RSS was higher in the RYGJ group than in the uRYGJ group, although the difference was not significant (7.7 vs. 0%; odds ratio (OR) 0.157; 95% confidence interval (CI) 0-1.059, p = 0.111). Comparison of endoscopic findings revealed that severe gastric stasis 1 year after surgery was significantly less frequent in the uRYGJ group (46.2 vs. 13.8%; OR 0.247; 95% CI 0.102-0.599, p = 0.002). The same result was reproduced 3 years after surgery (39.4 vs. 15.5%; OR 0.279; 95% CI 0.088-0.882, p = 0.030). CONCLUSIONS Compared with RYGJ, uRYGJ after laparoscopic distal gastrectomy is a safe and effective procedure for preventing severe postoperative gastric food stasis.

Abstract
Background Many observational studies have reported correlations between postoperative complications and prognosis after radical gastrectomy but the results are controversial. This meta-analysis was performed to investigate whether there is a correlation between postoperative complications and prognosis after radical gastrectomy. Methods Literature searches were performed in PubMed, EMBASE, and the Cochrane Library. Studies that investigated the correlations between any postoperative complications and prognosis after radical gastrectomy were included. The pooled hazard ratio (HR) with 95% confidence interval (CI) for postoperative complications regarding overall survival (OS) or recurrence-free survival (RFS) was calculated by using RevMan 5.3.5. Subgroup analyses were performed within pathological stages I, II, and III. Results Sixteen retrospective studies comprising 12,065 patients were included. The pooled HR (95% CI) for complications regarding OS was 1.79 (1.39, 2.30) and was 1.40 (1.06, 1.84) after excluding in-hospital mortality; the pooled HR (95% CI) for complications regarding RFS was 1.28 (1.10, 1.49). The pooled HR (95% CI) for infectious complications and leakage regarding OS was 1.86 (1.22, 2.83) and 2.02 (1.02, 4.00), respectively. The pooled HR (95% CI) for any reported postoperative complications regarding OS for stage I, II, and III diseases was 2.39 (0.77, 7.46), 4.35 (2.58, 7.35), and 2.84 (1.77, 4.56), respectively. Conclusions Postoperative complications correlate with poor prognosis after radical gastrectomy. Such correlations are found in stage II and III gastric cancer patients but remain to be determined in stage I gastric cancer patients.

Abstract
BACKGROUND Anastomotic leakage is a severe complication after gastric cancer surgery. Inadequate blood supply is regarded as an important risk factor. The aim of the study was to evaluate the feasibility and usefulness of intraoperative assessment of anastomotic vascular perfusion in gastric cancer surgery using near-infrared (NIR) camera imaging with indocyanine green (ICG)-enhanced fluorescence technique. MATERIALS AND METHODS From March 2015 to 2016, 30 patients undergoing laparoscopic gastrectomy for gastric cancer were prospectively evaluated. After completing the anastomosis, 2.5-5.0 mg of ICG was injected via peripheral veins. All anastomoses and resection margins were investigated using NIR camera to assess anastomotic perfusion. The assessment was performed using the adopted perfusion score of fluorescence activity, which ranged from 1 to 5 (1 = no uptake, and 5 = iso-fluorescent to all other segments). RESULTS Twenty-six distal gastrectomy (20 gastroduodenostomies, 6 gastrojejunostomies), 3 total gastrectomies (TG), and 1 pylorus-preserving gastrectomy were performed. The gap of visualization was 4.1 ± 3.2 minutes (range, 2-15) after ICG injection. Twenty-three of 30 patients (76.7%) showed technically successful ICG visualization. Among gastroduodenostomies, the average scores for gastric and duodenal sides were 3.5 and 3.7. Among gastrojejunostomies, the average scores for gastric, jejunal, and duodenal stump sides were 3.5, 4.0, and 3.8 (jejunojejunostomy, 3.5). Among TG, the average scores for esophagojejunostomy, duodenal stump, and jejunojejunostomy were 3.7, 4.0, 4.0, and 4.7. One case of leakage occurred in this study. Other complications included fluid collection and stenosis in 1 patient each. CONCLUSIONS This study showed intraoperative ICG angiography using NIR camera is feasible and provides imaging of anastomotic blood flow. Further studies are needed for practice.

Abstract
BACKGROUND Postoperative inflammatory complications are associated with poorer prognosis in gastrointestinal malignancies. The aims of this study were to clarify the impact of postoperative inflammation itself on overall survival (OS) and relapse-free survival (RFS) in advanced gastric cancer patients. METHODS We retrospectively analyzed 490 patients who underwent curative resection for pStage II and III gastric cancer from 2005 to 2008. We evaluated postoperative inflammation based on duration of hyperthermia (body temperature ≥38 °C) and leukocytosis (≥12,000/µL-1). OS and RFS were compared between a prolonged inflammation group and non-prolonged inflammation group. Multivariate analysis using the Cox proportional hazard model was performed to identify independent prognostic factors. RESULTS The prolonged inflammation group comprised 57 (11.7%) patients who had hyperthermia for 4 days or longer and 42 (8.6%) patients who had leukocytosis for 7 days or longer. OS and RFS were significantly worse in the prolonged hyperthermia group (OS: hazard ratio (HR) 1.84, 95% confidence interval (CI) 1.19-2.73, P = 0.004; RFS: HR 1.66, 95% CI 1.08-2.45, P = 0.015). The prolonged leukocytosis group also showed significantly worse OS (HR 1.92, 95% CI 1.19-2.96, P = 0.004) and RFS (HR 1.90, 95% CI 1.19-2.88, P = 0.004). Multivariate analysis identified prolonged hyperthermia as an independent factor for predicting poor prognosis (OS: HR 1.77, 95% CI 1.13-2.68, P = 0.013; RFS: HR 1.60; 95% CI 1.03-2.39, P = 0.038). CONCLUSIONS Prolonged hyperthermia and leukocytosis after curative gastrectomy were associated with poorer OS and RFS in advanced gastric cancer patients.

Evaluation of Anastomotic Leak after Esophagectomy for Esophageal Cancer: Typical Time Point of Occurrence, Mode of Diagnosis, Value of Routine Radiocontrast Agent Studies and Therapeutic Options. Dig Surg 2017; 35:419-426. [PMID: 29131024 DOI: 10.1159/000480357] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 08/08/2017] [Indexed: 12/13/2022]
Abstract
BACKGROUND Data on the typical time point of occurrence of anastomotic leak (AL) after esophagectomy for esophageal cancer are currently scarce. Therefore, the usefulness of routine radiocontrast agent studies (RRCS) for testing proper healing of the anastomosis after esophagectomy remains unclear. Furthermore, preferred available tools to diagnose postoperative AL and therapeutic options are still under debate. METHODS We present a retrospective analysis of 328 consecutive patients who underwent esophagectomy for esophageal cancer between 2005 and 2015. A RRCS has been performed to date in our center on the fifth postoperative day (POD), before returning to normal oral intake. RESULTS In total, 49 of 328 patients developed AL after esophagectomy (15%). A total of 11 patients (23%) developed AL before the RRCS and 34 patients (69%) after an unremarkable RRCS; and 4 patients (8%) with AL were diagnosed by RRCS, resulting in overall sensitivity of 16%. The median time point of occurrence of AL was POD 9, the majority of AL (84%) occurred between POD 1 and 19. Computed tomography led to the diagnosis of AL in 41% of patients. The most frequent therapy of AL was stenting in 47% of patients. Endoscopic vacuum therapy was used in 4 patients. CONCLUSIONS The majority of AL occurred within the first 3 weeks after esophagectomy without a typical time point. In our series, RRCS on the fifth POD had a low sensitivity of 16%. Therefore, standardized RRCS and fasting till the examination cannot be generally recommended. In case of clinical suspicion of AL, computed tomography of the chest and abdomen with oral contrast agent should be performed, followed by endoscopy. Endoscopic stent placement remains the standard therapy of AL in our center. Endoscopic vacuum therapy evolves as it is an interesting alternative therapeutic option and can be combined with stenting in selected cases.

Abstract
AIM Anastomotic leak is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may induce overexpression of tumour progression-related genes in immune cells. The aim was to investigate the effect of postoperative intra-abdominal infection on the gene expression patterns of peripheral blood leucocytes (PBL) after surgery for colorectal cancer. METHOD Prospective matched cohort study. Patients undergoing surgery for colorectal cancer were included. Patients who had anastomotic leak or intra-abdominal abscess were included in the infection group (n = 23) and matched with patients without complications for the control group (n = 23). PBL were isolated from postoperative blood samples. Total RNA was extracted and hybridized to the Affymetrix Human Gene 1.0 ST microarray. RESULTS Patients in the infection group displayed 162 upregulated genes and 146 downregulated genes with respect to the control group. Upregulated genes included examples coding for secreted cytokines involved in tumour growth and invasion (S100P, HGF, MMP8, MMP9, PDGFC, IL1R2). Infection also upregulated some proangiogenic genes (CEP55, TRPS1) and downregulated some inhibitors of angiogenesis (MME, ALOX15, CXCL10). Finally, some inhibitors (HP, ORM1, OLFM4, IRAK3) and activators (GNLY, PRF1, FGFBP2) of antitumour immunity were upregulated and downregulated, respectively, suggesting that the inflammatory environment caused by a postoperative infection favours immune evasion mechanisms of the tumour. CONCLUSION Analysis of PBL shows differential expression of certain tumour progression-related genes in colorectal cancer patients who have a postoperative intra-abdominal infection, which in turn may promote the growth of residual cancer cells to become recurrent tumours.

Abstract
BACKGROUND Laparoscopically-assisted gastrectomy (LAG) has been established to be a minimally invasive treatment for early gastric cancer. However, few studies have shown the feasibility of LAG in patients with risky comorbidities according to the American Society of Anesthesiologists physical status (ASA-PS) classification. We performed this retrospective cohort study to assess the feasibility of LG in patients with an ASA-PS class of 3 or higher. METHODS We retrospectively identified 214 patients with an ASA-PS class of 3 or 4 among 1192 patients who underwent radical gastrectomy with lymph-node dissection between 1999 and 2014 in our hospital. Finally, 106 patients were generated by propensity-score matching between LAG and open gastrectomy (OG). Postoperative complications were compared between LAG and OG. RESULT The overall incidence of complications was the same in LAG (30%) and OG (30%). Surgical complications were similar in LAG and OG (19% and 17%, p = 0.80). Medical complications also did not differ significantly between LAG and OG (21% and 15%, p = 0.45). CONCLUSION LAG was a feasible procedure for patients with gastric cancer who had an ASA-PS class of 3 or 4 and could undergo general anesthesia. LAG can become an optional treatment for such risky patients.

Abstract
Minimally invasive surgery (MIS) for upper gastrointestinal (GI) cancer, characterized by minimal access, has been increasingly performed worldwide. It not only results in better cosmetic outcomes, but also reduces intraoperative blood loss and postoperative pain, leading to faster recovery; however, endoscopically enhanced anatomy and improved hemostasis via positive intracorporeal pressure generated by CO2 insufflation have not contributed to reduction in early postoperative complications or improvement in long-term outcomes. Since 1995, we have been actively using MIS for operable patients with resectable upper GI cancer and have developed stable and robust methodology in conducting totally laparoscopic gastrectomy for advanced gastric cancer and prone thoracoscopic esophagectomy for esophageal cancer using novel technology including da Vinci Surgical System (DVSS). We have recently demonstrated that use of DVSS might reduce postoperative local complications including pancreatic fistula after gastrectomy and recurrent laryngeal nerve palsy after esophagectomy. In this article, we present the current status and future perspectives on MIS for gastric and esophageal cancer based on our experience and a review of the literature.

Abstract
INTRODUCTION Laparoscopic distal gastrectomy (LDG) with D1+ lymph node dissection (LND) for early gastric cancer has been widely accepted. However, LDG with D2 LND for advanced gastric cancer remains in limited use. The aim of this retrospective study was to clarify the safety of LDG with D2 LND for gastric cancer. METHODS From January 2010 to September 2014, 296 patients underwent LDG; those who received D1+ LND (n = 230) or D2 LND (n = 66) were included in this study. The clinicopathological characteristics and short-term outcomes of both groups were investigated and compared. RESULTS There were no significant differences in the incidence of postoperative complications between the two groups. However, the frequency of infectious intra-abdominal complications was higher in the D2 LND group than in the D1+ LND group. Additionally, a lower risk of infectious intra-abdominal complications was seen with certified than with uncertified operators. CONCLUSION The evaluation of short-term outcomes demonstrated that LDG with D2 LND is generally feasible. However, the risk of infectious intra-abdominal complications is higher with D2 LND than with D1+ LND. Also, D2 LND should be performed by trained operators.

Abstract
BACKGROUND A partially covered self-expandable metallic stent (PCSEMS) is of proven benefit in palliation of unresectable or inoperable malignant gastric outlet obstruction. However, its use in patients with benign anastomotic stricture after laparoscopy-assisted gastrectomy (LAG) is not well established. METHODS Patients who between May 2007 and June 2012 underwent PCSEMS placement for management of benign gastrointestinal obstruction after LAG were included in this retrospective analysis. The primary outcomes were the technical success and clinical success of the PCSEMS. The secondary outcomes were procedure-related complications and PCSEMS dysfunction. RESULTS Eleven patients (six women, five men, mean age 53.5 years, range 15-76 years) underwent successful placement of a PCSEMS for management of benign anastomotic strictures after LAG and were followed-up for a mean of 20.6 months (range 7.9-55.6 months). The mean gastric outlet obstruction scoring system (GOOSS) score was 0.36 before PCSEMS placement and 1.55 (p = 0.010) 24-48 h after PCSEMS placement. All of the patients were able to tolerate a solid diet (GOOSS score 3) after 1 week. There were no major or minor procedure-related complications. Stent dysfunction occurred in four patients (three distal migrations, one proximal migration), and stent removal was successful in all of the remaining patients after a mean of 2.0 months (1.1-3.0 months). Obstructive symptoms recurred in two patients (one after proximal migration, one after stent removal) and were treated successfully with PCSEMS reinsertion and balloon dilation. CONCLUSIONS A PCSEMS may be a feasible and effective option for management of benign anastomotic strictures after LAG which could avoid secondary surgery.

Abstract
BACKGROUND D2 total gastrectomy combined with splenectomy or pancreaticosplenectomy reportedly increases morbidity and mortality. Totally laparoscopic total gastrectomy (TLTG) for advanced gastric cancer (AGC) remains controversial because of its technical difficulties and lack of long-term results. We determined the feasibility and safety of TLTG for AGC. METHODS A single-institution retrospective study was conducted. Ninety-two consecutive AGC patients who underwent radical TLTG were enrolled. The primary end point was morbidity. The patients were observed for 3 years following TLTG. We assessed short-term surgical and long-term outcomes, including 3-year overall survival rates (3yOS) and 3-year recurrence-free survival rates (3yRFS). RESULTS Early and late morbidities (Clavien-Dindo grade ≥3) were 26.1 and 6.5 %, respectively. Operative time, estimated blood loss, number of dissected lymph nodes, and postoperative hospital stay were 444 (278-694) min, 100 (0-2267) g, 48 (16-89), and 23 (9-136) days, respectively, and 3yOS and 3yRFS rates were 70.7 and 60.9 %, respectively. Factors associated with postoperative complications and 3yOS were operative time [OR 1.011 (1.006-1.017), p < 0.01] and cancer recurrence within 3 years [HR 312.191 (1.126-86573.245], p = 0.045], respectively. 3yRFS was associated with tumor size (≥50 mm) [HR 10.325 (1.328-80.289), p = 0.026], pathological N factor ≥2 [HR 3.188 (1.196-8.495), p = 0.02], and postoperative pancreatic fistula combined with intra-abdominal abscesses Clavien-Dindo grade ≥2; [HR 3.670 (1.440-9.351), p = 0.006]. CONCLUSIONS TLTG for AGC is sufficiently feasible and safe from both surgical and oncological point of view.

Abstract
OBJECTIVE This study aimed to compare the short-term surgical outcomes and cost-benefits following totally laparoscopic distal gastrectomy (TLDG) and laparoscopy-assisted distal gastrectomy (LADG) for the treatment of gastric cancer. METHODS Between April 2007 and December 2013, a total of 100 patients with gastric cancer underwent laparoscopic distal gastrectomy. The patients were classified into two groups according to whether intracorporeal anastomosis or extracorporeal anastomosis had been performed. The comparison between the groups was based on clinicopathological characteristics and surgical and economic outcomes. RESULTS There were 57 and 43 patients who underwent TLDG and LADG, respectively. The patients' demographics and tumor characteristics did not show any statistically significant differences with the exception for tumor location. In the LADG group, tumors were localized to relatively higher positions (p = 0.024) and received Roux-en-Y reconstruction more frequently (p < 0.001). There were no differences in the incidence of morbidity. Anastomotic leakage was not recorded in either group, although anastomotic stenosis occurred in one patient (1.8 %) after TLDG and in two patients (4.7 %) after LADG. Compared with the LADG group, the TLDG group was associated with significantly less operative blood loss (p < 0.001), a shorter time to oral intake (p = 0.012), and hospital stay (p = 0.018). The median operation costs were greater in the TLDG group than in the LADG group (¥982,000 in TLDG vs. ¥879,830 in LADG; p < 0.001), whereas the median total hospital costs were similar between the two groups (¥1302,665 in LADG vs. ¥1383,322 in TLDG: p = 0.119). CONCLUSION This study suggests that TLDG is as technically feasible, safe, and effective as LADG for treating patients with gastric cancer. Furthermore, TLDG is associated with equivalent total hospital costs compared with LADG. The increased operation cost is offset by the decreased costs associated with longer periods of hospitalization.

Which is a more reliable indicator of survival after gastric cancer surgery: Postoperative complication occurrence or C-reactive protein elevation? J Surg Oncol 2015; 112:894-9. [PMID: 26458724 DOI: 10.1002/jso.24067] [Citation(s) in RCA: 53] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2015] [Accepted: 09/29/2015] [Indexed: 12/18/2022]
Abstract
BACKGROUND AND OBJECTIVES The impact of postoperative complications on long-term outcome has been reported in several types of malignancies. However, it is unclear why postoperative complications affect long-term outcome. The aim of this study is evaluating whether postoperative complication occurrence or C-reactive protein (CRP) elevation better reflects long-term outcome in gastric cancer patients. METHODS This study included 305 patients who underwent curative surgery for pT2-T4b gastric cancer. Patients were divided into two groups based on the peak CRP value (CRPmax): low (<12 mg/dl) and high CRPmax (≥ 12 mg/dl). A multivariate analysis was conducted to identify independent prognostic factors for recurrence-free survival (RFS). RESULTS Postoperative complications (≥ Grade II) occurred in 86 of 305 patients (28.2%). Although CRP elevation (P = 0.001) and postoperative complication occurrence (P = 0.045) was each significantly associated with RFS in the univariate analysis, multivariate analysis identified CRP elevation (P = 0.017) but not complication occurrence (P = 0.682) as an independent prognostic factor. Among patients without complications, those in the high CRPmax group had significantly worse RFS than those in the low CRPmax group (P = 0.004). CONCLUSIONS CRP elevation is a more reliable indicator of survival after gastric cancer surgery than postoperative complication occurrence. Surgeons should minimize the postoperative inflammatory response to improve prognosis.

Abstract
Purpose Although several studies report risk factors for anastomotic leakage after gastrectomy for gastric cancer, they have yielded conflicting results. The present retrospective cohort study was performed to identify risk factors that are consistently associated with anastomotic leakage after gastrectomy for stomach cancer. Materials and Methods All consecutive patients who underwent gastrectomy at a single gastric surgical unit between May 2003 and December 2012 were identified retrospectively. The associations between anastomotic leakage and 23 variables related to patient history, diagnosis, and surgery were assessed and analyzed with logistic regression. Results In total, 3,827 patients were included. The rate of anastomotic leakage was 1.88% (72/3,827). Multiple regression analysis showed that male sex (P=0.001), preoperative/intraoperative transfusion (P<0.001), presence of cardiovascular disease (P=0.023), and tumor location (P<0.001) were predictive of anastomotic leakage. Patients with and without leakage did not differ significantly in terms of their 5-year survival: 97.6 vs. 109.5 months (P=0.076). Conclusions Male sex, cardiovascular disease, perioperative transfusion, and tumor location in the upper third of the stomach were associated with an increased risk of anastomotic leakage. Although several studies have reported that an anastomotic complication has a negative impact on long-term survival, this association was not observed in the present study.

Abstract
BACKGROUND Laparoscopic distal gastrectomy (LDG) is a routinely performed procedure. However, clinical expertise in laparoscopic total gastrectomy (LTG) is insufficient, and it is only performed at specialized institutions. This study aimed to identify critical factors associated with complications after laparoscopic gastrectomy (LG), particularly LTG. METHODS A large-scale database was used to identify critical factors influencing the early outcomes of LTG. Of 1248 patients with resectable gastric cancer who underwent LG, 259 underwent LTG. Predictive risk factors were determined by analyzing relationships between clinical characteristics and postoperative complications. Major complications after LTG were analyzed in detail. RESULTS Multivariate analysis of all LG procedures revealed LTG as a risk factor for complications. Morbidity in the LDG and LTG groups was 6.2 % (52 of 835 patients) and 22.4 % (58 of 259 patients), respectively. Major post-LTG complications included anastomotic leakages and pancreatic fistulae. The rate of anastomotic leakage was significantly higher in the LTG group (5.0 %) than in the LDG group (1.2 %); however, it showed a tendency to decrease in more recent cases. Pancreatic fistulae occurred frequently after LTG with D2 lymphadenectomy (LTG-D2), particularly in cases of concomitant pancreatosplenectomy. Obesity was also associated with pancreatic fistula formation after LTG with pancreatosplenectomy. CONCLUSIONS Compared with LDG, LTG is a developing procedure. Advances in the surgical techniques associated with the LTG procedure will improve the short-term outcomes of esophagojejunostomy. With regard to LTG-D2, establishing optimal and safe #10 node dissection is one of the most urgent issues. Pancreatic fistula after LTG with pancreatosplenectomy must be investigated in the future.

Abstract
OBJECTIVE The aim of this study was to investigate the effect of postoperative peritoneal infection on proliferation, migration, and invasion capacities of cancer cells lines in vitro after surgery for colorectal cancer. BACKGROUND Anastomotic leakage is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may enhance tumor progression features of residual cancer cells. METHODS Prospective matched cohort study. Patients undergoing surgery for colorectal cancer with curative intent (January 2008-March 2012) were included. Patients who had an anastomotic leak or intra-abdominal abscess were included in the infection group (n=47). For each case patient, another patient with an uncomplicated postoperative course was selected for the control group (n=47).In vitro treatments on cancer cell lines (MDA-MB-231 and SW620) were performed using baseline and postoperative serum and peritoneal fluid samples to determine cell proliferation and cell migration/invasion activities. RESULTS Postoperative peritoneal fluid from infected patients enhanced both cell migration (infection: 140±85 vs control: 94±30; P=0.016) and cell invasion (infection: 117±31 vs control: 103±16; P=0.024) capacities of cancer cell lines. With serum samples, these effects were only observed in cell migration assays (infection: 98±28 vs control: 87±17; P=0.005). Some minor activation of cell proliferation was observed by treatment with serum from infection group. Two-year cumulative disease-free survival was significantly lower in patients with postoperative peritoneal infection (infection: 77.6% vs control: 90.6%; P=0.032). CONCLUSIONS Our results suggest that postoperative peritoneal infection enhances the invasive capacity of residual tumor cells after surgery, thus facilitating their growth to recurrent tumors.

End of the road for a dysfunctional end organ: laparoscopic gastrectomy for refractory gastroparesis. J Gastrointest Surg 2015; 19:411-7.

Abstract
INTRODUCTION Gastroparesis is a functional disorder resulting in debilitating nausea, esophageal reflux, and abdominal pain and is frequently refractory to medical treatment. Therapies such as pyloroplasty and neurostimulators can improve symptoms. When medical and surgical treatments fail, palliative gastrectomy is an option. We examined outcomes after gastrectomy for postoperative, diabetic, and idiopathic gastroparesis. METHODS A prospective database was queried for gastrectomies performed for gastroparesis from 1999 to 2013. Primary outcomes were improvements in pre- versus postoperative symptoms at last follow-up, measured on a five-point scale. Secondary outcome was operative morbidity. RESULTS Thirty-five patients underwent laparoscopic total or near-total gastrectomies for postoperative (43 %), diabetic (34 %), or idiopathic (23 %) gastroparesis. Antiemetics and prokinetics afforded minimal relief for one third of patients. There were no mortalities. Six patients suffered a leak, all treated with surgical reintervention. With a median follow-up of 6 months, nausea improved or resolved in 69 %. Chronic abdominal pain improved or resolved in 70 %. Belching and bloating resolved for 79 and 89 %, respectively (p < 0.01). CONCLUSIONS Regardless of etiology, medically refractory gastroparesis can be a devastating disease. Near-total gastrectomy can ameliorate or relieve nausea, belching, and bloating. Chronic abdominal pain commonly resolved or improved with resection. Despite attendant morbidity, gastrectomy can effectively palliate symptoms of gastroparesis.

Abstract
BACKGROUND Anastomotic leakage is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. The aim was to investigate the inflammatory and angiogenic responses in patients undergoing surgery for colorectal cancer who had postoperative intra-abdominal infection, and to compare the results with patients without complications. METHODS Consecutive patients undergoing surgery for colorectal cancer with curative intent were included. Patients who had an anastomotic leak or intra-abdominal abscess were included in the infection group and matched with patients who had an uncomplicated postoperative course. IL-6 and VEGF were measured in serum and peritoneal fluid. RESULTS Serum concentration of IL-6 was higher in the infection group (n = 30) compared with the control group (n = 30) on day 4 (infection: 42.3 [27.6-1473.2] versus control: 0.6 [0.6-17.1] pg/ml; p = 0.008). IL-6 in peritoneal fluid was higher in the infection group at 48 h and day 4 (infection: 1000.2 [995.4-1574.0] versus control: 90.3 [35.2.6-106.1] pg/ml; p = 0.001). Serum VEGF was higher in the infection group on day 4 (infection: 1128.6 [427.3-10000.0] versus control: 438.3 [214.1-677.6] pg/ml; p = 0.001). Peritoneal VEGF concentration was higher in the infection group at 48 h and day 4 (infection: 10000.0 [2563.0-10000.0] versus control: 477.8 [313.5-814.4] pg/ml; p = 0.001). Two-year recurrence rate was higher in patients with infection (infection: 30% versus control: 4%; p = 0.001). CONCLUSIONS Intra-abdominal infection increases IL-6 and VEGF after surgery for colorectal cancer. Amplification of inflammation and angiogenesis might be one of the mechanisms responsible for the higher recurrence rate observed in patients with anastomotic leakage or intra-abdominal abscess.

Abstract
BACKGROUND The oncologic impact of anastomotic leakage after rectal cancer surgery remains controversial. METHODS Between January 1999 and December 2010, 1,148 patients with rectal cancer who underwent curative surgery with sphincter preservation were retrospectively reviewed. Using the propensity score matching method, 328 patients with fibrin glue were matched to 328 patients without fibrin glue, and oncologic outcomes were compared in the matched groups. RESULTS Anastomotic leakage was diagnosed in 76 patients (6.6%). On multivariate analysis, fibrin glue was the independent predictor of prevention of anastomotic leakage. In the 656 matched groups, patients with anastomotic leakage had significantly worse 5-year local recurrence-free survival and disease-free survival than those without leakage. Multivariate analysis confirmed that anastomotic leakage was an independent prognostic factor of both local recurrence and disease-free survival, but the use of fibrin glue was not associated with the long-term outcomes when controlling for confounders. CONCLUSIONS Anastomotic leakage is a major independent prognostic factor for long-term outcomes. Fibrin glue has a protective effect of anastomosis, without oncologic advantages.

Abstract
Background The aim of this study was to investigate the differences and influencing factors for postsurgical gastroparesis syndrome incidence after laparoscopic and open radical gastrectomy. Methods Clinical data were collected for 563 patients who underwent open radical gastrectomy for gastric cancer and 72 cases receiving laparoscopic radical gastrectomy. We retrospectively analyzed the incidence of postsurgical gastroparesis syndrome, clinical features, course of disease, and risk factors of these two groups. Results There was no statistical difference for the incident rate of postsurgical gastroparesis syndrome between laparoscopic and open radical gastrectomy (6.9% vs. 3.7%, P > 0.05). Preoperative outflow tract obstruction and Billroth II anastomosis were the two risk factors for postsurgical gastroparesis syndrome in the open radical gastrectomy group and the laparoscopic surgery for gastric cancer group. The same results were obtained from logistic regression statistical analysis. Age greater than 70 years was also one of the risk factors for postsurgical gastroparesis syndrome in the open radical gastrectomy group (P < 0.05). Conclusions Laparoscopic radical gastrectomy for gastric cancer does not increase the incident rate of postsurgical gastroparesis syndrome.
