BACKGROUND: Neoadjuvant therapy enhances the possibility of achieving radical resection and improves the prognosis for locally advanced gastric cancer (GC). However, there is a lack of evidence regarding the optimal extent of resection for locally advanced proximal GC after neoadjuvant therapy. METHODS: In this study, 330 patients underwent resection in Peking University Cancer Hospital, with curative intent after neoadjuvant therapy for histologically confirmed proximal GC from January 2009 to December 2022. RESULTS: In this study, 45 patients underwent proximal gastrectomy (PG), while 285 underwent total gastrectomy (TG). After propensity-score matching, 110 patients (71 TG and 39 PG) were included in the analysis. No significant differences between PG and TG regarding short-term outcomes and long-term prognosis were found. Specifically, PG demonstrated comparable overall survival to TG ( P = 0.47). Subgroup analysis revealed that although not statistically significant, PG showed a potential advantage over TG in overall survival for patients with tumor-long diameters less than 4 cm ( P  = 0.31). However, for those with a long diameter larger than 4 cm, TG had a better survival probability ( P  = 0.81). No substantial differences were observed in baseline characteristics, surgical safety, postoperative recovery, and postoperative complications. CONCLUSION For locally advanced proximal GC with objective response to neoadjuvant therapy (long diameter <4 cm), PG is an alternative surgical procedure.

With the advancement of surgical treatment for gastric cancer surgery, the preservation of gastric function to reduce the post-operative impacts on patients' quality of life, while ensuring effective surgical outcomes, have become both patients' expectations and the pursuit of surgeons. The emergence of the concept of function-preserving gastrectomy (FPG) marks the entry of surgical treatment of gastric cancer into a more personalized and precise era. The "Chinese expert consensus on function - preserving gastrectomy for gastric cancer(2021 edition)" was the first systematic effort to define FPG, outlining its indications and surgical approaches. In recent years, with the rapid development of surgical technologies, such as functional visualization, lymph node tracing, vascular navigation, and multi-omics imaging artificial intelligence (AI), the concept and practice of FPG have continued to evolve. Therefore, led by the the Gastrointestinal Surgery Branch, Surgery Branch, Chinese Medical Association (CMA) with Chinese Society of Surgical Oncology of Chinese Medical Doctor Association (CMDA), Chinese Society of Upper Gastrointestinal Surgeon of CMDA, Stomach and Intestines Committee of Chinese Anticancer Association, and the Gastric Cancer Committee of the Chinese Anticancer Association, a group of experts has come together to update and refine the consensus based on domestic and international literature, as well as recent researches and clinical practice. The definition of FPG remains consistent with the 2021 edition, emphasizing the goal of achieving radical resection for early gastric cancer while minimizing the scope of surgery, selecting appropriate reconstruction methods, and preserving as much gastric function as possible. The main surgical techniques include those that reduce the extent of surgery (such as pylorus-preserving gastrectomy, segmental gastrectomy, local gastric resection, and endoscopic resection), proximal gastrectomy (PG), and distal gastrectomy with vagus nerve preservation. After PG, the surgical reconstruction of the digestive tract involves procedures such as anastomosis between the distal remnant stomach and esophagus, esophagus-tube stomach anastomosis, double tract reconstruction (DTR), interposition jejunostomy, side to side gastroesophagostomy (SOFY), and double flap gastroesophagostomy (Kamikawa anastomosis). In recent years, new anti-reflux techniques have emerged, such as the tube-shaped stomach "Giraffe anastomosis", modified SOFY anastomosis, single flap gastroesophagostomy, arch-shaped anastomosis, and tunnel anastomosis. Functional assessment after FPG primarily includes evaluating remnant gastric function, function-related complications, post-operative nutritional status, and quality of life. This updated consensus is expected to standardize the practice of FPG, provide more personalized surgical treatment options for patients with gastric cancer, and further improve their post-operative quality of life.

Objective: To investigate the feasibility and safety of modified interposed jejunal anastomosis following total laparoscopic proximal gastrectomy. Methods: The modification in the digestive tract reconstruction involves transecting the small intestine 2-3 cm below the gastrojejunostomy site and relocating the enteroenterostomy cranially, based on the double-tract anastomosis technique. Specifically, the jejunum and its mesenteric vessels are transected 20-25 cm from the ligament of Treitz. An overlap anastomosis is performed between the esophagus and the distal jejunum, with the common opening closed using a 15 cm barbed suture in a buried manner. A side-to-side gastrojejunostomy is completed under natural anatomical alignment, and the common opening is closed similarly. A side-to-side anastomosis is then created between the small intestine approximately 10 cm below the gastrojejunal anastomosis and the small intestine distal to the ligament of Treitz. Finally, the small intestine is transected 2-3 cm below the gastrojejunal anastomosis without dividing the mesenteric vessels. Results: From April to December 2024, a total of five patients with adenocarcinoma of the esophagogastric junction underwent modified interposed jejunum anastomosis following totally laparoscopic proximal gastrectomy at the Affiliated Tumor Hospital of Xinjiang Medical University. The median age of the group was 56 (53-74) years, including four males and one female, with a median body mass index of 24 (21-29) kg/m². Three cases were classified as Siewert type II and two as type III. All five patients successfully completed the totally laparoscopic proximal gastrectomy with modified interposed jejunum anastomosis. The median operative time was 215 (165-240) minutes, the digestive tract reconstruction time was 75 (65-93) minutes, and the intraoperative blood loss was 50 (30-100) ml. The median time to postoperative flatus was 71 (68-88) hours, with no severe complications occurring in any case. The median postoperative hospital stay was 8 (8-9) days. Within three months after surgery, none of the patients reported reflux symptoms such as acid regurgitation or heartburn. Conclusions: Total laparoscopic modified interposed jejunal anastomosis is safe and feasible, with relatively simple operative steps. It effectively prevents reflux while ensuring the passage of food through the remnant stomach and duodenal loop.

OBJECTIVES: Gastric cancer (GC) is the fifth most common cancer and the third leading cause of cancer-related death worldwide, posing a serious threat to public health. Prognostication of overall survival (OS) in patients undergoing radical gastrectomy remains a clinical priority. Evidence suggests that preoperative nutritional and inflammatory status correlated with postoperative outcomes. This study aims to evaluate the prognostic value of the skeletal muscle index at the third lumbar vertebra (L3-SMI) as a trichotomous variable and to compare the performance of commonly used nutritional and inflammation-related indicators in predicting postoperative survival in GC patients. METHODS: This retrospective study analyzed clinical data of patients who underwent radical gastrectomy with neoadjuvant chemotherapy between 2011 and 2018 at the Department of Gastrointestinal Surgery, Xiangya Hospital of Central South University. L3-SMI was measured by preoperative CT, and 8 preoperative nutritional/inflammatory indices were calculated from the latest laboratory tests before surgery: neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), pan-immune-inflammation value (PIV), albumin-globulin ratio (AGR), and prognostic nutritional index (PNI). L3-SMI was categorized into 3 groups using X-tiler software. ROC curves were used to determine optimal cut-off values for the other eight indices. Kaplan-Meier curves and univariate/multivariate Cox proportional hazards models were used to analyze the association between variables and OS. Concordance index (C-index) and subgroup analysis assessed predictive performance and consistency across patient subgroups. RESULTS: A total of 546 patients were included, with a minimum follow-up time of 36 months. Kaplan-Meier and univariate analysis showed that L3-SMI and the 8 indicators were significantly associated with OS (all P<0.01). After adjusting for age, gender, tumor site, differentiation, pTNM stage, type of surgery, anemia, CEA, and AFP, multifactorial Cox analysis revealed that L3-SMI (HR=0.676, 95% CI 0.523 to 0.872), AGR (HR=0.611, 95% CI 0.452 to 0.827), and PNI (HR=0.590, 95% CI 0.418 to 0.833) were independent predictors of OS. The full model confirmed the independent prognostic roles of L3-SMI, AGR, and PNI. Among all indicators, PNI had the highest C-index for 1-year OS prediction (0.632, 95% CI 0.568 to 0.695), while AGR showed the best performance at 3 years (0.585, 95% CI 0.548 to 0.622) and 5 years (0.578, 95% CI 0.542 to 0.613). Subgroup analysis indicated that higher L3-SMI, AGR, and PNI were associated with lower mortality risk in patients aged<65 years, with lower gastric tumors, poor differentiation, stage III pTNM, or who underwent subtotal gastrectomy. CONCLUSIONS Compared with other indicators, preoperative nutritional markers such as L3-SMI, AGR, and PNI demonstrated superior prognostic value for OS in gastric cancer patients undergoing radical gastrectomy. Assessing these indices can help identify patients at high risk of poor prognosis, thereby guiding targeted nutritional interventions and potentially improving survival outcomes.

Bariatric and metabolic surgery has become a primary treatment for decompensated obesity, with the number of procedures rapidly increasing in China in recent years. Various improved and novel surgical techniques have emerged. Given the characteristics of the Chinese obese population lower body mass index compared to Western populations and frequent pancreatic islet dysfunction laparoscopic Roux-en-Y gastric bypass remains one of the mainstream procedures in China. Although the Procedural Guideline for Laparoscopic Roux-en-Y Gastric Bypass (2019 Edition) has provided standardized surgical steps, mastering and routinely implementing the procedure in clinical practice continues to pose significant challenges. Compared to laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass is more technically demanding and requires a longer learning curve. To avoid suboptimal weight loss or severe postoperative complications resulting from non-standardized techniques, this article summarizes the authors' clinical experience, emphasizing key technical steps: creation of the gastric pouch, standardization of gastrojejunal and jejunojejunal anastomoses, hiatal closure, and full serosalization. These insights aim to improve procedural safety and therapeutic efficacy by offering a set of practical process optimization strategies.

BACKGROUND: The results of studies comparing Billroth-I (B-I) with Roux-en-Y (R-Y) reconstruction on the quality of life (QoL) are still inconsistent. The aim of this trial was to compare the long-term QoL of B-I with R-Y anastomosis after curative distal gastrectomy for gastric cancer. METHODS: A total of 140 patients undergoing curative distal gastrectomy with D2 lymphadenectomy in West China Hospital, Sichuan University from May 2011 to May 2014 were randomly assigned to the B-I group ( N  = 70) and R-Y group ( N  = 70). The follow-up time points were 1, 3, 6, 9, 12, 24, 36, 48, and 60 months after the operation. The final follow-up time was May 2019. The clinicopathological features, operative safety, postoperative recovery, long-term survival as well as QoL were compared, among which QoL score was the primary outcome. An intention-to-treat analysis was applied. RESULTS: The baseline characteristics were comparable between the two groups. There were no statistically significant differences in terms of postoperative morbidity and mortality rates, and postoperative recovery between the two groups. Less estimated blood loss and shorter surgical duration were found in the B-I group. There were no statistically significant differences in 5-year overall survival (79% [55/70] of the B-I group vs. 80% [56/70] of the R-Y group, P  = 0.966) and recurrence-free survival rates (79% [55/70] of the B-I group vs. 78% [55/70] of the R-Y group, P  = 0.979) between the two groups. The scores of the global health status of the R-Y group were higher than those of the B-I group with statistically significant differences (postoperative 1 year: 85.4 ± 13.1 vs . 88.8 ± 16.1, P  = 0.033; postoperative 3 year: 87.3 ± 15.2 vs . 92.8 ± 11.3, P  = 0.028; postoperative 5 year: 90.9 ± 13.7 vs . 96.4 ± 5.6, P  = 0.010), and the reflux (postoperative 3 year: 8.8 ± 12.9 vs . 2.8 ± 5.3, P  = 0.001; postoperative 5 year: 5.1 ± 9.8 vs . 1.8 ± 4.7, P  = 0.033) and epigastric pain (postoperative 1 year: 11.8 ± 12.7 vs. 6.1 ± 8.8, P  = 0.008; postoperative 3 year: 9.4 ± 10.6 vs. 4.6 ± 7.9, P  = 0.006; postoperative 5 year: 6.0 ± 8.9 vs . 2.7 ± 4.6, P  = 0.022) were milder in the R-Y group than those of the B-I group at the postoperative 1, 3, and 5-year time points. CONCLUSIONS: Compared with B-I group, R-Y reconstruction was associated with better long-term QoL by reducing reflux and epigastric pain, without changing survival outcomes.

BACKGROUND: Management of gastric leak after sleeve gastrectomy (SG) is challenging due to its unpredictable outcomes. We aimed to summarize the characteristics of SG leaks and analyze interventions and corresponding outcomes in a real-world setting. METHODS: To retrospectively review of 15,721 SG procedures from 2010 to 2020 based on a national registry. A cumulative sum analysis was used to identify a fitting curve of gastric leak rate. The Kaplan-Meier method and log-rank tests were performed to calculate and compare the probabilities of relevant outcomes. The logistic regression analysis was conducted to determine the predictors of acute leaks. RESULTS: A total of 78 cases of SG leaks were collected with an incidence of 0.5% (78/15,721) from this registry (6 patients who had the primary SG in non-participating centers). After accumulating 260 cases in a bariatric surgery center, the leak rate decreased to a stably low value of under 1.17%. The significant differences presented in sex, waist circumference, and the proportion of hypoproteinemia and type 2 diabetes at baseline between patients with SG leak and the whole registry population ( P = 0.005, = 0.026, <0.001, and = 0.001, respectively). Moreover, 83.1% (59/71) of the leakage was near the esophagogastric junction region. Leakage healed in 64 (88.9%, 64/72) patients. The median healing time of acute and non-acute leaks was 5.93 months and 8.12 months, respectively. Acute leak (38/72, 52.8%) was the predominant type with a cumulative reoperation rate >50%, whereas the cumulative healing probability in the patients who required surgical treatment was significantly lower than those requring non-surgical treatment ( P = 0.013). Precise dissection in the His angle area was independently associated with a lower acute leak rate, whereas preservation ≥2 cm distance from the His angle area was an independent risk factor. CONCLUSIONS Male sex, elevated waist circumference, hypoproteinaemia, and type 2 diabetes are risk factors of gastric leaks after SG. Optimizing surgical techniques, including precise dissection of His angle area and preservation of smaller gastric fundus, should be suggested to prevent acute leaks.

Objective: To investigate the safety and efficacy of laparoscopic surgery in locally advanced gastric cancer patients with neoadjuvant SOX chemotherapy combined with PD-1 inhibitor immunotherapy. Methods: Between November 2020 and April 2021, patients with locally advanced gastric cancer who were admitted to the Union Hospital of Tongji Medical College of Huazhong University of Science and Technology were prospectively enrolled in this study. Inclusion criteria were: (1) patients who signed the informed consent form voluntarily before participating in the study; (2) age ranging from 18 to 75 years; (3) patients staged preoperatively as cT3-4N+M0 by the TNM staging system; (4) Eastern Collaborative Oncology Group score of 0-1; (5) estimated survival of more than 6 months, with the possibility of performing R0 resection for curative purposes; (6) sufficient organ and bone marrow function within 7 days before enrollment; and (7) complete gastric D2 radical surgery. Exclusion criteria were: (1) history of anti-PD-1 or PD-L1 antibody therapy and chemotherapy; (2) treatment with corticosteroids or other immunosuppre- ssants within 14 days before enrollment; (3) active period of autoimmune disease or interstitial pneumonia; (4) history of other malignant tumors; (5) surgery performed within 28 days before enrollment; and (6) allergy to the drug ingredients of the study. Follow-up was conducted by outpatient and telephone methods. During preoperative SOX chemotherapy combined with PD-1 inhibitor immunotherapy, follow-up was conducted every 3 weeks to understand the occurrence of adverse reactions of the patients; follow-up was conducted once after 1 month of surgical treatment to understand the adverse reactions and survival of patients. Observation indicators were: (1) condition of enrolled patients; (2) reassessment after preoperative therapy and operation received (3) postoperative conditions and pathological results. Evaluation criteria were: (1) tumor staged according to the 8th edition of the American Joint Committee on Cancer (AJCC) TNM staging system; (2) tumor regression grading (TRG) of pathological results were evaluated with reference to AJCC standards; (3) treatment-related adverse reactions were evaluated according to version 5.0 of the Common Terminology Criteria for Adverse Events; (4) tumor response was evaluated by CT before and after treatment with RECIST V1.1 criteria; and (5) Clavien-Dindo complication grading system was used for postoperative complications assessment. Results: A total of 30 eligible patients were included. There were 25 males and 5 females with a median age of 60.5 (35-74) years. The primary tumor was located in the gastroesophageal junction in 12 cases, in the upper stomach in 8, in the middle stomach in 7, and in the lower stomach in 3. The preoperative clinical stage of 30 cases was III. Twenty-one patients experienced adverse reactions during neoadjuvant chemotherapy combined with immunotherapy, including four cases of CTCAE grade 3-4 adverse reactions resulting in bone marrow suppression and thoracic aortic thrombosis. All cases of adverse reactions were alleviated or disappeared after active symptomatic treatment. Among the 30 patients who underwent surgery, the time from chemotherapy combined with immunotherapy to surgery was 28 (23-49) days. All 30 patients underwent laparoscopic radical gastrectomy, of which 20 patients underwent laparoscopic-assisted radical gastric cancer resection; 10 patients underwent total gastrectomy for gastric cancer, combined with splenectomy in 1 case and cholecystectomy in 1 case. The surgery time was (239.9±67.0) min, intraoperative blood loss was 84 (10-400) ml, and the length of the incision was 7 (3-12) cm. The degree of adenocarcinoma was poorly differentiated in 18 cases, moderately differentiated in 12 cases, nerve invasion in 11 cases, and vascular invasion in 6 cases. The number lymph nodes that underwent dissection was 30 (17-58). The first of gas passage, the first postoperative defecation time, the postoperative liquid diet time, and the postoperative hospitalization time of 30 patients was 3 (2-6) d, 3 (2-13) d, 5 (3-12) d, and 10 (7-27) d, respectively. Postoperative complications occurred in 23 of 30 patients, including 7 cases of complications of Clavien-Dindo grade IIIa or above. Six patients improved after treatment and were discharged from hospital, while 1 patient died 27 days after surgery due to granulocyte deficiency, anemia, bilateral lung infection, and respiratory distress syndrome. The remaining 29 patients had no surgery-related morbidity or mortality within 30 days of discharge. Postoperative pathological examination showed TRG grades 0, 1, 2, and 3 in 8, 9, 4, and 9 cases, respectively, and the number of postoperative pathological TNM stages 0, I, II, and III was 8, 7, 8, and 7 cases, respectively. The pCR rate was 25.0% (8/32). Conclusion: Laparoscopic surgery after neoadjuvant SOX chemotherapy combined with PD-1 inhibitor immunotherapy for locally advanced gastric cancer is safe and feasible, with satisfactory short-term efficacy. Early detection and timely treatment of related complications are important.

Gastric cancer is one of the most common gastrointestinal malignancies in China. D2 radical gastrectomy is the main treatment for advanced gastric cancer patients. With the advancement of laparoscopic technology, laparoscopic radical gastrectomy has been gradually developed in the world, and even popularized in China. There have been a lot of literature reports on the indications, the scope of lymph node dissection and the improvement of techniques of laparoscopic radical gastrectomy for gastric cancer. Relevant guidelines or consensus for radical gastrectomy. The prevention and treatment of complications of gastrointestinal reconstruction for laparoscopic radical gastric cancer surgery is a major concern for gastrointestinal surgeons. Once complications occur in digestive tract reconstruction, it would increase the hospitalization cost, prolong the hospitalization stay of patients, delay follow-up chemotherapy, and even lead to postoperative death or other serious consequences. Therefore, it is of positive and far-reaching clinical significance to pay attention to the techniques of gastrointestinal reconstruction after laparoscopic radical gastric cancer surgery, to reduce the occurrence of gastrointestinal reconstruction complications, and to detect and reasonably manage related complications in a timely manner. The Chinese expert consensus on prevention and treatment of complications related to digestive tract reconstruction after laparoscopic radical gastrectomy for gastric cancer (2022 edition) has significance value for reducing the occurrence of gastrointestinal reconstruction complications. This manuscript mainly serves as the interpretation and supplement of this Consensus.
