Incidental gallbladder cancer(IGC)is a type of gallbladder cancer identified during or after cholecystectomy for benign gallbladder diseases through intraoperative or postoperative pathological examination.Since gallbladder cancer often coexists with benign conditions such as gallstones and polyps,and routine abdominal ultrasound has limited sensitivity in early diagnosis,IGC accounts for more than two-thirds of all gallbladder cancer cases.To improve early diagnosis rates,high-risk patients should undergo high-resolution ultrasound after surgery,combined with the use of radiomics and molecular biomarkers to reduce misdiagnosis and missed diagnoses.Most IGC patients are diagnosed at early stages,with a high incidence of residual disease.Delayed radical surgery can effectively improve prognosis.However,for patients with locally advanced disease,radical surgery should not be performed indiscriminately,and conversion surgery may be a better option.The optimal timing for delayed radical surgery is within 2 to 8 weeks after the initial surgery,with specific timing based on the resolution of acute inflammation and the evaluation of tumor staging and metastasis.For patients with T1b and T2 stage cancer,liver segment IVb/V resection and lymph node dissection are recommended to ensure curative outcomes.The application of laparoscopic techniques in gallbladder cancer treatment is becoming increasingly widespread,with confirmed surgical safety and tumor control effects,leading to growing support for minimally invasive treatment among hepatobiliary surgeons.Additionally,indocyanine green-guided fluorescence laparoscopic technology allows for precise lymph node dissection and liver resection,reducing the risk of postoperative complications.In light of the complex anatomy in the hepatic hilum and hepatoduodenal ligament region in IGC patients,performing delayed radical surgery using the 3D laparoscopic PH approach(based on the portal vein and hepatic artery as the anatomical axis)helps prevent organ damage and tumor dissemination.This review summarizes the current surgical treatment of IGC and discusses the application of the PH approach in laparoscopic gallbladder cancer radical surgery.

With the rapid development of modern medical technology,minimally invasive surgical procedures are playing an increasingly important role in the field of pancreatic tumor treatment. This article systematically expounds on the application status of minimally invasive surgical procedures,including robotic surgery and laparoscopic surgery,in the treatment of pancreatic tumors. Through in-depth analysis of various surgical procedures such as pancreatoduodenectomy,distal pancreatectomy,local pancreatic resection,middle pancreatectomy and duodenum-preserving pancreatic head resection,combined with a large amount of high-quality randomized controlled trial research data in the past decade,it systematically discusses the advantages and limitations of minimally invasive surgery compared with traditional open surgery. It also explores the challenges faced by minimally invasive pancreatic surgery in aspects such as high technical difficulty of surgical operations,complex management of postoperative complications and evaluation of oncological radicality. Moreover,it comprehensively looks ahead to the development trends such as the refinement and innovation of future technologies,strengthened multidisciplinary collaboration,and the application of artificial intelligence and big data,aiming to provide references for the clinical practice and research of pancreatic surgery.

With the advancement of contemporary science and technology,minimally invasive surgery has assumed an increasingly indispensable role in the management of pancreatic diseases. In comparison to traditional open methods,minimally invasive pancreatic surgery is frequently associated with shorter hospital stays,reduced intraoperative blood loss,and decreased rates of general and pancreas-specific complications,albeit with longer operation times. However,additional research is required to elucidate the differences between minimally invasive and open surgical methods concerning overall survival and disease-free survival. The implementation of minimally invasive pancreatic surgery demands sophisticated equipment and necessitates extensive training for surgeons to surmount the procedural learning curve. To fully exploit the benefits of minimally invasive surgery in the treatment of pancreatic diseases,it is imperative to integrate cutting-edge scientific technologies,innovate perioperative management pathways,develop multidisciplinary collaborative models,and establish a standardized training system.

Objective:To compare the perioperative outcomes of laparoscopic duodenal-preserving pancreatic head resection(LDPPHR) with laparoscopic pancreaticoduodenectomy(LPD) in the treatment of borderline and benign diseases of the pancreatic head.Methods:This is a retrospective cohort study. Perioperative data from 87 patients with non-malignant pancreatic head diseases who underwent LDPPHR or LPD were retrospectively collected in the Department of Biliary-Pancreatic Surgery,Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology from January 2020 to December 2022. There were 49 male and 38 female patients with an age ( M(IQR)) of 57.0(16.5) years (range: 20 to 75 years). Forty patients underwent LDPPHR and 47 patients underwent LPD. Quantitative data following a normal distribution were compared using Student′s t-test, while quantitative data not following a normal distribution were compared using the Mann-Whitney U test. Comparisons of categorical or ordinal variables were made using χ2 test or Fisher′s exact test. Logistic regression analysis was used to estimate the risk factors associated with the rate of complications. Results:There were no statistically significant differences between the LDPPHR group and the LPD group in terms of reoperation rate,total hospital stay duration,postoperative hospital stay duration,90-day mortality rate,30-day and 90-day readmission rates,and 2-year tumor recurrence rate (all P>0.05). The complication rate was higher in the LDPPHR group compared to the LPD group (80.0%(32/40) vs. 51.1%(24/47), χ2=7.89, P=0.005),but there was no difference in the rate of Clavien-Dindo classification of surgical complications ≥Ⅲ between the two groups (10.0%(4/40) vs. 12.8%(6/47), χ2<0.01, P=0.947). Additionally,the rate of delayed gastric emptying (DGE) was higher in the LDPPHR group compared to the LPD group ( χ2=10.79, P=0.001),but there was no statistically significant difference in the rate of B,C grade DGE between the two groups ( χ2=0.48, P=0.487). There were no statistically significant differences in the rates of postoperative pancreatic fistula,bile leakage,post-pancreatectomy hemorrhage,intra-abdominal infection,and pulmonary infection between the two groups (all P>0.05). The results of the univariate logistic regression analysis showed that LDPPHR (compared to LPD, OR=3.83, 95% CI: 1.46 to 10.04, Z=2.73, P=0.006) and preoperative biliary stent placement (compared to non-use of biliary stent, OR=5.30, 95% CI: 1.13 to 25.00, Z=2.11, P=0.035) were risk factors for the complication rate,but neither was an independent risk factor for complication rate (all P>0.05). Conclusion:The preliminary results suggest that LDPPHR can achieve perioperative safety and effectiveness comparable to LPD.

Objective:To investigate the clinical value of the novel approach,radical resection of the retroperitoneal lipo-lymphatic layer (RRRLLL),in the surgical treatment of resectable pancreatic head cancer.Methods:Between June 2020 and June 2022,a total of 221 patients with pancreatic head cancer underwent surgical treatment using the RRRLLL approach(RRRLLL group),while 107 patients received traditional surgical treatment(traditional group) in five high-volume pancreatic centers in China. Data from surgical technique and clinical perioperative outcomes,including lymph node harvested,surgical time,and complications,were analyzed. The RRRLLL group consisted of 144 males and 77 females with an age of (67.5±9.0) years(range:41.3 to 81.1 years). The traditional group included 71 males and 36 females,with an age of (66.3±8.1) years(range:45.1 to 79.2 years). Statistical analysis was performed using the K-S test, Z test,or χ 2 test, respectively. Results:Pancreaticoduodenectomy was performed successfully in all patients,achieving R0 resection. RRRLLL group surgery required mobilization of retroperitoneal adipose and lymphatic tissues starting from the right edge of the inferior vena cava and extending to the left side,up to the superior mesenteric artery,down to the inferior mesenteric artery,and left to the left side of the aorta,including the perineural and lymphatic tissues around the superior mesenteric artery and the sheath of the mesenteric artery. However,the traditional group did not include the areas mentioned above in the scope of clearance. There were no statistically significant differences between the RRRLLL group and the traditional group in terms of age,sex,tumor size,T stage,and vascular invasion (all P>0.05). However,the number of lymph nodes harvested in the RRRLLL group was significantly higher at 28.7±9.0 (range: 18 to 39) compared to 18.2±8.0 (range: 12 to 21) in the traditional group ( Z=-10.691, P<0.05). There were no statistically significant differences in the number of positive lymph nodes,N staging,and postoperative complications between the two groups. Conclusion:The RRRLLL approach improved lymph node dissection compared to the traditional approach,potentially leading to reduced recurrence rates.
