Aim: To investigate the morbidity, mortality, recurrence and technical aspects of two distinct surgical strategies that were implemented in successive periods.
Methods: Ninty-two patients with 113 cysts underwent surgical procedures. The study was divided into 2 periods. Data from first period (P1) were compiled retrospectively. The surgical strategy was conservative surgery. The second period (P2) included a prospective study conducted according to a protocol following the criterion that radical procedures should be performed whenever it is technically feasible.
Results: Patients of both periods showed no statistically significant differences in age, gender, cyst location or mortality. Among the P2 group, patients exhibited more preoperative jaundice, and cyst size was smaller (P < 0.05). Changes in surgical strategy increased the rate of radical surgery, decreases morbidity and in-hospital stay (P < 0.001). A negative result in P2 was the death of two old patients (4.8%) who had undergone conservative treatments. The rate of radical surgery in P2 was around 75%.
Conclusion: Radical surgery should be the technique of choice whenever it is feasible, because it diminishes morbidity and in-hospital stay. Conservative surgery must be employed only in selected cases.

Background: In the last two decades, robotic-assisted gastrectomy has become a widely adopted surgical option for gastric cancer (GC) treatment. Despite its popularity, postoperative complications can significantly deteriorate patient quality of life and prognosis. Therefore, identifying risk factors for these complications is crucial for early detection and intervention.

Early recurrence (ER) following surgery for rectal cancer is a significant factor impacting patient survival rates. Tsai identified age, preoperative neoadjuvant therapy, length of hospital stay, tumour location, and pathological stage as factors influencing the risk of ER. Postoperative monitoring for ER should encompass a thorough medical history review, physical examination, tumour marker testing, and imaging studies.

Background: Pancreatic cancer involving the pancreas neck and body often invades the retroperitoneal vessels, making its radical resection challenging. Multimodal treatment strategies, including neoadjuvant therapy, surgery, and postoperative adjuvant therapy, are contributing to a paradigm shift in the treatment of pancreatic cancer. This strategy is also promising in the treatment of pancreatic neck-body cancer.

Department of General Surgery, Shenzhen University General Hospital, Shenzhen 518000, Guangdong Province, China.
Background: Malignant obstructive jaundice (MOJ) is characterized by the presence of malignant tumors infiltrating or compressing the bile duct, causing poor bile drainage, generalized yellowing, pain, itching, and malaise. MOJ is burdensome for both the society and the families of affected patients and should be taken seriously.
Aim: To evaluate the clinical effect of stent placement during endoscopic retrograde cholangiopancreatography for relieving MOJ and the efficacy of percutaneous transhepatic biliary drainage in terms of liver function improvement, complication rates, and long-term patient outcomes.

Background: Identifying factors that influence non-curative resection (NCR) is critical to optimize treatment strategies and improve patient outcomes in patients with early gastric cancer (EGC).
Aim: To investigate the factors influencing the NCR of EGC and to evaluate the predictive value of these factors.
Methods: The clinical data of 173 patients with EGC admitted between July 2020 and July 2023 were retrospectively collected.
