With advancements in surgical technology, minimally invasive and function- preserving approaches have become fundamental objectives of both patients and physicians. In recent years, laparoscopic endoscopic cooperative surgery (LECS) has gained increasing attention for its significant role in achieving these goals. However, a notable gap remains in the availability of evidence-based guidelines to standardize the clinical implementation of LECS for gastrointestinal tumors. This guideline is collaboratively developed by the Gastrointestinal Stromal Tumor Committee of the Chinese Anti-Cancer Association, Chinese Gastric Cancer Association, the NOTES Group of the Digestive Endoscopy Branch of the Chinese Medical Association, and the Greater Bay Area Laparoscopic Endoscopic Cooperative Surgery Alliance. Through integrating the current best evidence and experts' opinions, we developed 22 recommendations on 16 clinical questions, including the LECS indications, use of antibiotics, enhanced recovery after surgery, wound suture, and surgical training. This guideline provides comprehensive guidance and recommendations for LECS, aimed at promoting the precise, minimally invasive and function-preserving treatment of gastrointestinal tumors.

Acute Care Surgery (ACS) is an emerging discipline of general surgery that integrates trauma, emergency surgery, critical care medicine, and surgical rescue. It is a modern model for the diagnosis and treatment of patients with acute and critical abdominal conditions. Compared to the traditional model, ACS integrates the theories and techniques of trauma, critical care, and surgery. It consolidates surgical wards and intensive care units into a single department for operational management. The care of acute care patients is led by physicians who are qualified in both critical care medicine and surgery. This model improves efficiency and significantly reduces morbidity and mortality of patients. Both international and domestic hospitals have had multiple surgical rescue teams that have embarked on exploratory work in the development of ACS, accumulating a certain amount of experience. The Expert Working Group of Acute Care Surgery, Chinese Medical Doctor Association Division of Surgeons has formed a preliminary guideline for the development of the Department of Acute Care Surgery based on the current experience and accomplishment in China for the reference of hospitals at all levels.

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.

In recent years, significant progress has been made in the clinical and basic research on fecal microbiota transplantation (FMT) for the treatment of inflammatory bowel disease (IBD). With the continuous application of new microbiota-based diagnostic and therapeutic concepts in clinical practice, it is imperative to standardize the diagnostic and therapeutic processes of FMT for IBD and provide consensus recommendations based on the latest evidence from evidence-based medicine for clinical practitioners. Organized by the Chinese Society for Parenteral and Enteral Nutrition of the Chinese Medical Association, the Gut Microbiota and FMT Committee of the Chinese Society for Human Health Sciences, and the Gut Microbiota Committee of the Shanghai Preventive Medicine Association, and with reference to the latest international consensus and relevant research advancements, this consensus integrates the clinical practice experience of domestic experts to establish the "Consensus of Chinese experts on gut microbiota and fecal microbiota transplantation in inflammatory bowel disease (2025 edition)". This consensus provides 29 recommendations focusing on the selection of FMT indications, gut microbiota analysis, donor selection and quality control for IBD transplantation, considerations during the transplantation period, selection of transplantation routes and dosages, management of FMT-related complications, and future research directions, aiming to offer standardized guidance for the clinical application of FMT in the treatment of IBD.

Colorectal cancer (CRC) is one of the most common malignant tumors in China, ranking second in morbidity and fourth in mortality. Metastasis and recurrence are the leading causes of patient death, and the peritoneum is a frequent site of metastasis in CRC, second only to liver and lung metastases. However, the prognosis of peritoneal metastasis is much worse than hepatic and pulmonary metastasis. CRC peritoneal metastasis is challenging early diagnosis, presents with severe symptoms, and has a poor prognosis. It is crucial to emphasize standardized diagnosis and treatment for CRC peritoneal metastasis to improve patients' outcome and enhance their quality of life. This consensus, based on evidence-based medical evidence, revised the "Chinese Expert Consensus on the Diagnosis and Treatment of Colorectal Cancer Peritoneal Metastasis (2022 edition)" and reached a preliminary consensus on the definition, diagnosis, treatment, and prevention of CRC peritoneal metastasis, with the aim of guiding and standardizing the diagnosis and treatment of CRC peritoneal metastasis, developing reasonable and effective comprehensive treatment plans, prolonging survival time and improving quality of life for CRC peritoneal metastasis patients, thereby raising the overall level of diagnosis and treatment for CRC in China.

Permanent stoma is an important method often selected in the surgical treatment of colorectal cancer, mainly including but not limited to the sigmoid colon single-lumen stoma after abdominoperineal resection. Since the stoma needs to be retained permanently, preoperative intervention for the stoma, the stoma surgical procedure, prevention and treatment of complications, and long-term postoperative follow-up are all closely related to the patient's quality of life. Under the guidance of the Colorectal Surgery Group of the Society of Surgery, Chinese Medical Association, the Colorectal Tumor Professional Committee of the Chinese Medical Doctor Association, and the Anorectal Physicians Branch of the Chinese Medical Doctor Association, led by the Stoma Study Group of the Anorectal Physicians Branch of the Chinese Medical Doctor Association and with the academic support of Chinese Journal of Gastrointestinal Surgery, experts in related fields were gathered. By drawing on the latest domestic and international guidelines and relevant literature, combining clinical practice and expert opinions, and through repeated discussions and revisions, 24 recommendations were put forward for preoperative evaluation and preparation, surgical technical operation specifications, postoperative management, complication prevention and treatment, and long-term follow-up. The aim is to provide guidance for the clinical practice of permanent stoma in colorectal cancer surgery in China.

Enterostomy is an important means of treating colorectal cancer disease, and the nutritional problems of colorectal cancer patients with enterostomy are getting more and more attention. Malnutrition not only prolongs the hospitalization time of the patients and increases their economic burden, but also increases the incidence of patients' complications and death rate. At present, the nutritional management of colorectal cancer patients with enterostomy in China has not yet formed a consensus. Launched by the Chinese Society for Oncological Nutrition, experts with relevant backgrounds from multiple disciplines in China were invited, based on relevant references, the latest evidence and experts' clinical experience, and after several rounds of expert correspondence and expert demonstration meetings, to write the expert consensus on the whole-course nutritional management of colorectal cancer patients with enterostomy. The expert consensus centers on the teamwork model for the whole-course management of colorectal cancer patients with enterostomy, nutritional tertiary diagnosis, principles of nutritional therapy, perioperative nutritional management, nutritional management of intestinal stoma complications, and post-discharge nutritional management, aiming to provide standardized guidance for the whole-course nutritional management of patients with intestinal stoma.
