BACKGROUND:
Neoadjuvant chemoradiotherapy followed by radical surgery has been a common practice for patients with locally advanced rectal cancer, but the response rate varies among patients. This study aimed to develop a ResNet-Vision Transformer based magnetic resonance imaging (MRI)-endoscopy fusion model to precisely predict treatment response and provide personalized treatment.
METHODS:
In this multicenter study, 366 eligible patients who had undergone neoadjuvant chemoradiotherapy followed by radical surgery at eight Chinese tertiary hospitals between January 2017 and June 2024 were recruited, with 2928 pretreatment colonic endoscopic images and 366 pelvic MRI images. An MRI-endoscopy fusion model was constructed based on the ResNet backbone and Transformer network using pretreatment MRI and endoscopic images. Treatment response was defined as good response or non-good response based on the tumor regression grade. The Delong test and the Hanley-McNeil test were utilized to compare prediction performance among different models and different subgroups, respectively. The predictive performance of the MRI-endoscopy fusion model was comprehensively validated in the test sets and was further compared to that of the single-modal MRI model and single-modal endoscopy model.
RESULTS:
The MRI-endoscopy fusion model demonstrated favorable prediction performance. In the internal validation set, the area under the curve (AUC) and accuracy were 0.852 (95% confidence interval [CI]: 0.744-0.940) and 0.737 (95% CI: 0.712-0.844), respectively. Moreover, the AUC and accuracy reached 0.769 (95% CI: 0.678-0.861) and 0.729 (95% CI: 0.628-0.821), respectively, in the external test set. In addition, the MRI-endoscopy fusion model outperformed the single-modal MRI model (AUC: 0.692 [95% CI: 0.609-0.783], accuracy: 0.659 [95% CI: 0.565-0.775]) and the single-modal endoscopy model (AUC: 0.720 [95% CI: 0.617-0.823], accuracy: 0.713 [95% CI: 0.612-0.809]) in the external test set.
CONCLUSION
The MRI-endoscopy fusion model based on ResNet-Vision Transformer achieved favorable performance in predicting treatment response to neoadjuvant chemoradiotherapy and holds tremendous potential for enabling personalized treatment regimens for locally advanced rectal cancer patients.

BACKGROUND:
Over 20 million colonoscopies are performed in China annually. An automatic clinical decision support system (CDSS) with accurate semantic recognition of colonoscopy reports and guideline-based is helpful to relieve the increasing medical burden and standardize the healthcare. In this study, the CDSS was built under a hierarchical-label interpretable classification framework, trained by a state-of-the-art transformer-based model, and validated in a multi-center style.
METHODS:
We conducted stratified sampling on a previously established dataset containing 302,965 electronic colonoscopy reports with pathology, identified 2041 patients' records representative of overall features, and randomly divided into the training and testing sets (7:3). A total of five main labels and 22 sublabels were applied to annotate each record on a network platform, and the data were trained respectively by three pre-training models on Chinese corpus website, including bidirectional encoder representations from transformers (BERT)-base-Chinese (BC), the BERT-wwm-ext-Chinese (BWEC), and ernie-3.0-base-zh (E3BZ). The performance of trained models was subsequently compared with a randomly initialized model, and the preferred model was selected. Model fine-tuning was applied to further enhance the capacity. The system was validated in five other hospitals with 3177 consecutive colonoscopy cases.
RESULTS:
The E3BZ pre-trained model exhibited the best performance, with a 90.18% accuracy and a 69.14% Macro-F1 score overall. The model achieved 100% accuracy in identifying cancer cases and 99.16% for normal cases. In external validation, the model exhibited favorable consistency and good performance among five hospitals.
CONCLUSIONS
The novel CDSS possesses high-level semantic recognition of colonoscopy reports, provides appropriate recommendations, and holds the potential to be a powerful tool for physicians and patients. The hierarchical multi-label strategy and pre-training method should be amendable to manage more medical text in the future.

BACKGROUND:
China has made significant progress in medical accessibility and quality over the past decades, and quality improvements in gastroenterology and digestive endoscopy have been consistent. The study aimed to describe the status quo of gastroenterology and digestive endoscopy in the Chinese mainland based on the data from the National Clinical Improvement System (NCIS) and the Hospital Quality Monitoring System (HQMS).
METHODS:
Data were extracted from the NCIS and the HQMS. Data analysis included general information from the Department of Gastroenterology and Endoscopy centers, management of inpatients and outpatients, and annual volume and quality indicators of digestive endoscopy. Acute pancreatitis, gastrointestinal bleeding, inflammatory bowel disease, and cirrhosis were identified as priority diseases and were subjected to detailed analysis.
RESULTS:
Data from 4620 and 7074 hospitals were extracted from the NCIS and HQMS, respectively. In 2023, 9.6 gastroenterologists, 6.7 endoscopists, and 37.3 gastroenterology beds per hospital nationwide were observed, achieving 19,252.4 outpatient visits, 1615.2 hospitalizations (97.0 for acute pancreatitis, 146.1 for gastrointestinal bleeding, 40.2 for inflammatory bowel disease, and 111.4 for cirrhosis), and 9432.7 digestive endoscopic procedures per hospital. Overall, the quality of practice improved significantly. The proportion of early cancer among gastrointestinal cancers increased from 11.1% in 2015 to 23.4% in 2023, and the adenoma detection rate during colonoscopy increased from 19.3% in 2019 to 26.9% in 2023. Regarding priority diseases, hospitalizations increased, and 31-day unplanned readmission rates decreased between 2019 and 2023. The median hospitalization costs and median proportion of medication costs decreased for acute pancreatitis, gastrointestinal bleeding, and cirrhosis. However, it increased for inflammatory bowel disease.
CONCLUSION
This report evaluates the status quo and development of gastroenterology and digestive endoscopy in the Chinese mainland, providing guidance for future quality improvements.

6.Expert consensus on laparoscopic and robotic-assisted pancreatoduodenectomy with resection and reconstruction of portal-superior mesenteric vein (2025).
Chinese Journal of Surgery 2025;63(6):461-470
Pancreatoduodenectomy with portal-superior mesenteric vein resection and reconstruction can provide radical surgical opportunities for patients with venous invasion and enable them to benefit from the surgery. With the development of minimally invasive concepts and surgical techniques, laparoscopic and robot-assisted pancreatoduodenectomy with portal-superior mesenteric vein resection and reconstruction is being increasingly widely carried out. This surgical procedure is highly technically demanding, and the perioperative management of patients is complex. However, there is a lack of high-quality and high-level evidence-based clinical studies in this regard. In order to better standardize the clinical application of laparoscopic or robot-assisted pancreatoduodenectomy with portal-superior mesenteric vein resection and reconstruction in China, the Study Group of Minimally Invasive Treatment for Pancreatic Cancer in China Anti-Cancer Association, guided by problems and based on evidence, formed 17 recommendations through full discussions among experts. The recommendations involve the safety, oncological benefits, and perioperative patient management of the minimally invasive approach to pancreatoduodenectomy with portal-superior mesenteric vein resection and reconstruction.

7.Technical guidelines for minimally invasive surgery in liver transplant recipients(2025).
Chinese Journal of Surgery 2025;63(10):859-865
Liver transplantation is an effective treatment for end-stage liver disease. Liver transplantation is technically complex and associated with significant trauma. In recent years,minimally invasive surgical techniques,such as laparoscopy and robotic surgery,have rapidly developed and been widely applied across various surgical fields. Minimally invasive surgery offers advantages including reduced trauma,less bleeding,and faster postoperative recovery,and has become a mainstream trend in surgical development. In the field of liver transplantation,laparoscopic and robotic donor hepatectomy techniques for living donor liver transplantation have made significant progress. However, due to difficulties in exposing the anastomotic sites of the donor liver and challenges in vascular anastomosis,the application of minimally invasive techniques in donor liver implantation has progressed relatively slowly. With advancements in laparoscopic and robotic surgical techniques and related instruments,laparoscopic donor liver implantation has gradually become feasible. Currently,multiple liver transplant centers worldwide have begun to progressively perform laparoscopic or robot-assisted liver transplantation in recipients,demonstrating potential advantages in reducing surgical trauma and accelerating postoperative recovery. However,there is currently a lack of guidelines or consensus on the application of minimally invasive surgery in liver transplant recipients. Therefore,Branch of Organ Transplantation of Chinese Medical Association,Surgery Group of Chinese Society of Surgery of Chinese Medical Association,and Branch of Organ Transplant Physicians of Chinese Medical Doctor Association invited experts in the field to discuss clinical issues. Combining published guidelines,consensus statements,and research advancements,they formulated the "Technical guidelines for minimally invasive surgery in liver transplant recipients(2025)", aiming to provide reasonable guidance and references for clinical practitioners in the field of liver transplantation.

8.Consensus on magnetic anchoring for tissue retraction and field exposure in laparoscopic surgery(2025).
Chinese Journal of Surgery 2025;63(10):873-877
Compared with traditional laparotomy,laparoscopy is restricted to the location and number of trocars,making it still faces many problems such as "chopstick effect", insufficient exposure of viscera and tissues,and limited surgical field. Magnetic-anchoring technology,as an innovative method specifically designed to assist tissue retraction and broaden surgical field in laparoscopy,has been applied in a variety of surgical procedures,including hepatobiliary surgery,thoracic surgery,gastrointestinal surgery,weight loss and metabolic surgery,gynecology,urology and other departments. Thus,it is of great significance to standardize the clinical application of magnetic-anchoring technology in assisting tissue retraction and broaden surgical field in laparoscopic surgery. This consensus was built according to evidence from published clinical researches and relative experiences,and was shaped based on key literature collection and discussion about practicing magnetic anchoring technology assisted laparoscopic tissue retraction and surgical field exposure. Further,this consensus was drafted by experts from related field,and was revised by 38 invited units and 68 invited professionals across China,from which the suggestions were collected and verified by the corresponding authors to officially establish this consensus.

OBJECTIVE:
To investigate the effectivess of arthroscopic Wafer surgery combined with triangular fibrocartilage complex (TFCC) insertion point reconstruction in the treatment of Palmer type ⅡC combined with typeⅠB ulnar impingement syndrome.
METHODS:
The clinical data of 14 patients with Parlmer type ⅡC combined with type ⅠB ulnar impingement syndrome who met the selection criteria between July 2021 and April 2024 were retrospectively analyzed. There were 7 males and 7 females with an average age of 43 years ranging from 16 to 59 years. The causes of injury were fall in 8 cases and sprain in 6 cases. The time from injury to operation ranged from 1 to 6 months, with an average of 2.3 months. Distal radioulnar joint instability was found in all cases. Arthroscopic Wafer surgery combined with TFCC insertion point reconstruction was used. The effectiveness was evaluated by comparing the wrist flexion-dorsiflexion range of motion, wrist ulnar deviation-radial deflection range of motion, forearm pronation-supination range of motion, visual analogue scale (VAS) score, and modified Mayo wrist score before and after operation.
RESULTS:
All patients were followed up 6-12 months, with an average of 9.1 months. The positive variation of ulna was (3.2±0.7) mm before operation, and the negative variation of ulna was (2.2±0.6) mm after operation. There was a significant difference in ulna variation between pre- and post-operation ( t=23.851, P<0.001). The pain symptoms and forearm rotation function of the patients after operation significantly improved. At last follow-up, the wrist flexion-dorsiflexion range of motion, wrist ulnar deviation-radial deflection range of motion, forearm pronation-supination range of motion, VAS score, and modified Mayo wrist score significantly improved when compared with those before operation ( P<0.05).
CONCLUSION
Arthroscopic Wafer surgery combined with TFCC insertion point reconstruction can effectively relieve wrist pain, enhance the stability of the distal radioulnar joint, and restore the function of the wrist in patients with Palmer type ⅡC combined with type ⅠB ulnar impingement syndrome.
