A unicornuate uterus with a non-communicating rudimentary horn is a rare Müllerian duct anomaly that is frequently underdiagnosed because of its variable clinical presentation and the limitations of conventional imaging modalities. Although not considered a direct cause of infertility, it may coexist with other reproductive pathologies and contribute to adverse reproductive outcomes. Presented here is a case series of three infertile women aged 30–36 years who were diagnosed with a unicornuate uterus and non-communicating rudimentary horn during fertility evaluation. Patient A presented with primary infertility, cyclic pelvic pain, endometriosis, and bilateral tubal disease; Patient B had a seven-year history of primary infertility and was initially suspected to have unilateral tubal obstruction; and Patient C was referred with a presumed diagnosis of uterine didelphys and was subsequently found to have a unicornuate uterus with a non-communicating rudimentary horn and ipsilateral renal agenesis. In all three cases, preoperative imaging failed to establish the definitive diagnosis, which was confirmed intraoperatively through laparoscopy, chromotubation, and hysteroscopy. Patients A and B underwent laparoscopic excision of the rudimentary horn with ipsilateral salpingectomy, while Patient C underwent only ipsilateral salpingectomy. Hysteroscopic transillumination was utilized in one case to facilitate safe laparoscopic dissection and delineation of the hemiuterine anatomy. All patients had uneventful postoperative recovery and were subsequently counseled regarding fertility options. This case series highlights the diagnostic challenges posed by unicornuate uterus with a non-communicating rudimentary horn, emphasizes the importance of a high index of suspicion during infertility work-up, and demonstrates the value of minimally invasive surgical management and hysteroscopic transillumination in selected cases. Early recognition and individualized treatment may help reduce reproductive complications and improve fertility counseling and management.

Appendicitis is one of the most commonly encountered general surgery emergencies worldwide and has been extensively studied. However, anatomical variations in the position of the appendix may result in atypical clinical presentations, leading to diagnostic difficulty and delays in management. Reported here is a case of subhepatic appendicitis in a young adult patient who successfully underwent laparoscopic appendectomy. Subhepatic appendicitis is a rare surgical entity that should be considered in patients presenting with right upper quadrant abdominal pain. Contrast-enhanced computed tomography and laparoscopy are valuable tools in the diagnosis and management of this uncommon condition.

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.

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.

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.

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.

The incidence of hiatal hernia is on the rise due to population aging and improved awareness of the disease. Laparoscopic repair is the main treatment modality; however, there remains a lack of consensus on the selection of mesh materials and operative specifications. Based on high-level evidence, this expert consensus has formulated 11 recommendations regarding the indications for mesh application, material selection, and operative methods: For patients with giant hiatal hernias (defect area >10 cm², hiatal diameter ≥ 5 cm, or over 1/3 of the gastric body entering the thoracic cavity), complex hernias, recurrent hernias, or those with weak diaphragmatic crura, mesh-reinforced repair is recommended to reduce the risk of recurrence. Synthetic meshes are suitable for giant/complex hernias; biological meshes help reduce foreign body reactions; and bioabsorbable synthetic meshes combine mechanical strength with safety. The preferred shape of the mesh is U-shaped, and fixation methods (non-absorbable sutures, absorbable staplers, or medical adhesives) are selected based on hernia size and anatomical features. For suturing the diaphragmatic crura, non-absorbable sutures are recommended, with the choice between interrupted or continuous suturing techniques tailored to patient characteristics. The method of fundoplication is determined according to esophageal pH measurement and lower esophageal sphincter pressure, and non-absorbable sutures are recommended for plication.

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.

OBJECTIVE: To investigate the safety and prognostic factors influencing the treatment of upper urinary tract urothelial carcinoma (UTUC) combined with bladder cancer (BCa) by laparoscopic simultaneous radical cystectomy and nephroureterectomy (RCNU). METHODS: The clinical data of patients admitted to Peking University Third Hospital for laparoscopic RCNU surgery from January 2009 to September 2023 were analyzed retrospectively. Based on the same gender, age (±5 years), history of uroepithelial tumors, underlying diseases, T-stage, N-stage, M-stage, American Society of Anesthesiologists (ASA) score, Charlson comorbidity index, and body mass index (BMI) (±5), 34 patients with RCNU were matched 1 ∶1 with patients with bladder cancer who underwent laparoscopic radical cystectomy (RC) alone. Kaplan-Meier survival analysis was used to calculate patient survival, and Cox proportional regression risk model was used to analyze clinical factors affecting prognosis. RESULTS: Of the 68 patients enrolled, the follow-up rate was 100% with a median follow-up time of 27.0 (11.7, 60.2) months. Comparison of intraoperative conditions (including operation time, estimated intraoperative bleeding, intra-operative blood transfusion, etc.) between the two groups of patients showed no significant difference (P>0.05). Comparison of preoperative creatinine and postoperative creatinine between the two groups of patients showed significant differences (P < 0.05). The perioperative Clavien grade Ⅲ-Ⅳ complication rates were 2.9% (1/34) in the RC group and 5.9% (2/34) in the RCNU group. There was no significant difference in terms of perioperative complications between the two groups. Overall survival was significantly lower in the patients receiving RCNU compared with the matched group receiving RC alone (P < 0.05). Cox regression analysis suggested that two factors, high N stage and high postoperative creatinine, were independent risk factors affecting the prognosis of patients in the 2 groups (P < 0.05). CONCLUSION The overall survival prognosis of patients undergoing RCNU surgery was worse compared with laparoscopic RC surgery alone during the same period. There was no clinically significant difference between the two groups in terms of operation time, intraoperative bleeding, and perioperative complications, and there were clinically significant differences in preoperative renal function and post-operative renal function.
