To explore and establish a China-specific same-day surgery model for hepatectomy based on the enhanced recovery after surgery (ERAS) concept, and to promote the clinical practice and standardized application of same-day surgery for hepatectomy in China. Organized by the Minimally Invasive Surgery Committee and Intelligent Medicine Committee of the Chinese Research Hospital Association, multidisciplinary experts in hepatobiliary surgery, anesthesiology, and nursing, integrating literature evidence with clinical practice, deliberated on key clinical issues encompassing the establishment of a same-day surgery system for hepatectomy, process management, patient selection and assessment, perioperative multimodal management, discharge criteria, and follow-up monitoring, leading to the formulation of this expert consensus. The consensus specifies the qualification requirements for hospitals and surgeons performing same-day surgery for hepatectomy, establishes a multidimensional patient selection system based on pathological, physiological, psychological, and social support dimensions, standardizes whole-course management strategies covering operative technical essentials, perioperative anesthetic management, multimodal analgesia and antiemesis, and early discharge assessment, and clarifies principles for post-discharge follow-up and emergency management. The formulation of this consensus provides a basis for safety margins and quality assurance in same-day surgery for hepatectomy, and holds significant practical value and exemplary significance for advancing the alignment of China′s liver surgery practices with international standards, unlocking the potential of high-quality medical resources, and improving patients′ experience during treatment.

Female genital tract congenital anomalies represent a complex spectrum of congenital developmental anomalies, posing long-standing challenges in diagnosis and treatment. Traditional examination methods, such as ultrasound, magnetic resonance imaging (MRI), and diagnostic laparoscopy, have limitations in assessing the internal structures of the vagina, cervix, and uterine cavity. As an emerging minimally invasive endoscopic technique, vaginal endoscopy provides a revolutionary tool for the precise evaluation and treatment of reproductive tract malformations by directly accessing the vaginal fornix and uterine cavity through natural orifices. This article aims to elucidate the technical advantages of vaginal endoscopy, explore its specific applications and benefits in the diagnosis, classification, and treatment of various female reproductive tract malformations, and analyze the current challenges and future development directions, with the goal of providing a helpful reference for clinical practice.

To evaluate the efficacy and safety of laparoscopic intraperitoneal onlay mesh repair with the keyhole technique (IPST) versus the Sugarbaker technique for the treatment of parastomal hernia.

A retrospective analysis was conducted on 31 patients with parastomal hernia following abdominoperineal resection (Miles′ operation) for rectal cancer. These patients underwent laparoscopic repair, either with the IPST (n=16, 51.6%) or the Sugarbaker technique (n=15, 48.4%), in the Second Department of General Surgery, Shanghai Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine, between Jan. 2020 and Jun. 2023. Patient demographic data, postoperative complications, and the primary outcome-recurrence rate-were collected. Postoperative follow-up exceeded 12 months.

No mortality was recorded within 6 months postoperatively. One patient (6.7%) in the Sugarbaker group was readmitted due to postoperative fever and recovered conservatively during follow-up. The recurrence rate was 13.3%(2 cases) in the Sugarbaker group and 12.5%(2 cases) in the IPST group. Furthermore, no significant differences were observed between the IPST and Sugarbaker groups regarding intraoperative details or postoperative complications, including abdominal distension, surgical site infection, intestinal obstruction, enteric fistula, chronic postoperative pain, or recurrence.

Both the Sugarbaker and IPST techniques have been demonstrated to be effective, feasible, safe, and to yield similar clinical outcomes in the surgical management of parastomal hernia, particularly with respect to their low recurrence rates.

To investigate the clinical efficacy and safety of stepwise percutaneous cholangioscopy-guided laser technique for treating biliary-enteric anastomotic stricture after pancreaticoduodenectomy (PD).

Clinical data of 11 patients with biliary-enteric anastomotic stricture after PD who underwent treatment with stepwise percutaneous cholangioscopy-guided laser technique in the Department of Hepatobiliary and Pancreatic Surgery, Hangzhou First People′s Hospital Affiliated to Medical School of Westlake University from Jul. 2020 to Jun. 2025 were retrospectively analyzed. The puncture approach, interval time, number of procedures, operative time, intraoperative blood loss, and perioperative complications (including postoperative bile leakage and bleeding) were recorded and analyzed, along with long-term outcomes.

All 11 patients successfully completed the procedures without conversion to laparotomy. A right hepatic approach was used in 4 cases and a left hepatic approach in 7 cases. The median interval from puncture to operation was 7 days. The median operative time was 153 min, and the median intraoperative blood loss was 10 ml. Three patients underwent two-stage procedures. Postoperatively, fever occurred in 3 patients, no postoperative bleeding, bile leakage, or other complications were observed. The median postoperative bilirubin level was 21.3 μmol/L, and the median time to catheter removal was 7 days. During follow-up (median 24 months), no obvious abdominal pain or jaundice occurred, and no patient required readmission for reoperation.

With meticulous preoperative planning and refined operative technique, the stepwise percutaneous cholangioscopy-guided laser technique is safe and effective for treating biliary-enteric anastomotic stricture after PD, with no restenosis of the biliary-enteric anastomosis observed in long-term follow-up.

To investigate the efficacy and safety of direct visualization diagnosis andmanagement of complex biliary diseases via percutaneous transhepatic choledochoscopy.

A retrospective cohort study was conducted on patients who underwent percutaneous transhepatic diagnostic or therapeutic procedures at the Department of Hepatobiliary and Liver Transplantation Surgery, Nanjing Drum Tower Hospital Affiliated to Nanjing University, from Jan. 2024 to Dec. 2025. Outcome measures included surgery success rate, complication incidence, biliary biopsy success rate, pathological concordance rate, and residual biliary stone rate.

A total of 16 patients were enrolled. Among them, 9 (9/16, 56.3%) underwent choledochoscopy with biopsy, 6 (6/16, 37.5%) received lithotripsy and stone extraction, and 3 (3/16, 18.8%) underwent balloon dilation for biliary stricture—with 1 (1/3, 33.3%) of the latter each group combining biopsy and stone extraction. 11 (11/16, 68.8%) patients were achieved predefined surgical plan.5 (5/9, 55.6%) cases were obtained tissue samples. Notably, 2 (2/16, 12.5%) patients preoperatively diagnosed with hilar cholangiocarcinoma were reclassified via biopsy as having hepatocellular carcinoma with biliary tumor thrombi, leading to a complete revision of their treatment regimens. Operative times varied by procedure: choledochoscopy with biopsy (44.2 ± 18.0 min), balloon dilation with stenting (38.3±5.8 min), and lithotripsy with stone extraction (76.7 ± 22.7 min). Mean intraoperative blood loss was 9.1±8.4 ml, with no patients requiring blood transfusion, interventional hemostasis, or surgical hemostasis. 1 patient developed minor bile leakage from an intra-abdominally displaced drainage tube, which resolved following endoscopic retrograde cholangiopancreatography (ERCP). No patients were transferred to the intensive care unit due to complications, and there were no cases of tumor seeding along the sinus tract and mortality case.

Percutaneous transhepatic choledochoscopy under direct visualization is a safe and feasible approach for diagnosing and treating complex biliary diseases. Sinus tract establishment remains a key technical challenge. Integration of multidisciplinary equipment is recommended, and direct-visualization biopsy via choledochoscopy provides a reliable pathway for definitive pathological diagnosis.

The Hepatobiliary and Pancreatic Medical Center of People′s Hospital of Xinjiang Uygur Autonomous Region, in collaboration with the Department of Hepatopancreatobiliary Surgery of The First Medical Center of Chinese PLA General Hospital, successfully performed a 5G remote robotic-assisted hepatic hydatid cyst resection in a patient with situs inversus totalis (mirror-image person) using a robotic surgical system. The straight-line spatial distance of this remote surgery was approximately 3000 km, with a total operation duration of 150 minutes, including 110 minutes of remote control operation. The intraoperative blood loss was 50 ml, no network interruption or robot-related adverse events occurred during the entire operation, and the patient recovered smoothly and was discharged on the 6th day after surgery. This case is the world′s first remote robot-assisted hepatic hydatid cyst resection in a patient with situs inversus totalis. The successful surgery solved the problem of surgical adaptation caused by the mirrored inversion of anatomical structures in patients with situs inversus totalis, achieved precise synchronization and low-latency control of 5G remote robotic surgery, and at the same time broke the geographical barriers of medical resources, opening up a new path for remote multi-team collaborative diagnosis and treatment of special cases.

To investigate the clinical safety and feasibility of single-incision laparoscopic sleeve gastrectomy combined with single-anastomosis stomach-ileal bypass (SILSG-SASI) in patients with moderate obesity and metabolic syndrome.

We report the clinical practice of a 39-year-old male patient with moderate obesity and severe metabolic dysfunction who underwent SILSG-SASI treatment.

The surgical procedure was completed successfully without the need for additional trocar placement or conversion to open surgery. No serious perioperative complications occurred. The patient achieved a favorable recovery and was discharged on the third postoperative day. Short-term follow-up confirmed significant weight loss and marked improvement in metabolic parameters, including blood glucose and lipid profiles.

For patients with moderate obesity, the SILSG-SASI procedure is technically feasible and offers perioperative safety benefits. Short-term follow-up results demonstrate effective weight reduction and metabolic improvement.

To investigate a case of right mesocolic hernia accidentally found during right hemicolectomy in adults, so as to improve the correct understanding of this disease.

A case of right mesocolic hernia was selected from the Department of Colorectal Surgery of Qilu Hospital of Shandong University, and the relevant literature was reviewed.

The patient was a middle-aged male who underwent laparoscopic right hemicolectomy due to poor conservative treatment for ascending colon diverticulitis. Malrotation of the small intestine was accidentally found during the operation. The operation was successfully completed and the patient was discharged successfully.

Congenital malrotation of the small intestine in adults is rare and usually diagnosed during surgery. Relevant imaging examinations are helpful for diagnosis of the disease. In addition, CT images should be carefully read before surgery to identify possible variations, so as to calmly cope with them during surgery and ensure the life safety of patients to the greatest extent.

To explore the application of laparoscopic single-site surgery in the resection of rectovaginal septum endometriosis.

A retrospective analysis was conducted on 1 case of rectovaginal septum endometriosis (RVSE) treated with laparoscopic single site surgery in Jun. 2023 at the First Affiliated Hospital of Guangxi Medical University.

The patient received laparoscopic single site surgery and no recurrence was found during the 2-year follow-up. Surgical skills include exposure, anatomy, priority protection and identification of lesions.

Laparoscopic single site surgery is safe and feasible to remove rectovaginal septum endometriosis.

Laparoscopic surgery is an important branch of minimally invasive surgery. Due to its advantages of less trauma, faster postoperative recovery and fewer complications, it has been widely used in abdominal tumor surgery in various surgical subspecialties such as hepatobiliary, pancreatic and gastrointestinal surgery. However, laparoscopic surgery also faces limitations such as reliance on two-dimensional vision, increased operational complexity, and high requirements for surgeons′ experience, and its accuracy and safety still need to be improved. Recently, with its powerful data processing, image recognition and automatic decision-making capabilities, artificial intelligence (AI) has developed rapidly in cross-disciplinary applications in medicine, promoting the development of laparoscopic surgery toward precision and intelligence. In this review, we summarize the current applications of AI in laparoscopic abdominal tumor surgery, including preoperative evaluation and planning, intraoperative localization, prediction of postoperative complications, and postoperative rehabilitation. We also analyze the existing challenges in the application of these technologies, including data bias, model interpretability and ethical issues. Furthermore, from the clinical perspective of the hepatobiliary surgery subspecialty, we discuss the future technological development trends and clinical translation prospects in this field. This review aims to provide a reference for promoting the interdisciplinary integration of artificial intelligence and laparoscopic surgery and improving the level of surgical diagnosis and treatment.
