Epidemiological studies have indicated a possible connection between cholecystectomy and digestive system malignancies. However, the precise relationship is still not fully understood. The primary objective of this study was to delineate the causal relationship between cholecystectomy and digestive system malignancy.

Precise resection margins are crucial in gastric cancer surgery to optimize oncological outcomes and reduce postoperative functional disorders. Fluorescent marking clips (ZEOCLIP FS; Zeon Medical Co, Ltd) have demonstrated potential in improving resection line accuracy during laparoscopic gastrectomy. However, the original ZEOCLIP FS contained insufficient fluorescent dye, limiting its visibility with the Firefly mode of the da Vinci Surgical System. To address this limitation, a new version with increased dye concentration, the ZEOCLIP FS Marker, was developed. This study aimed to evaluate the utility and safety of the enhanced ZEOCLIP FS Marker in robot-assisted gastric cancer surgery.

Gastric cancer surgery is associated with significant morbidity. Obesity is a risk factor for short-term complications. However, previous studies on the role of body mass index (BMI) as a predictor of long-term survival have conflicting results, and contemporary population-based data in the Western population are lacking. This study aimed to compare the long-term survival after gastric cancer surgery among patients who were underweight (BMI of <18.5 kg/m), those with normal weight (BMI of 18.5-24.9 kg/m), those who were overweight (BMI of 25.0-29.9 kg/m), and those who were obese (BMI of >30.0 kg/m).

The RefluxStop procedure, shown to effectively eliminate gastroesophageal reflux disease (GERD) symptoms in clinical trial, has been offered at our clinic since 2020. Promising short-term outcomes in initial cohorts have been published; we now present outcomes for 100 patients with follow-up of at least 1 year.

Hypoglycemia is a common adverse outcome after bariatric surgery. Preoperative factors are important to predict worse hypoglycemic incidence. This study aimed to evaluate preoperative risk factors associated with the incidence of hypoglycemia after bariatric surgery.

Optimal treatment for locoregional pancreatic cancer includes chemotherapy and surgical resection. Chemotherapy can be difficult to tolerate, requiring dose-reductions or missed cycles. This study aims to evaluate rates of dose-reduction and outcomes based on relative dose intensity (RDI) of chemotherapy received.

The primary goal of this study was to create a preoperative risk stratification tool for CR-POPF after PD, using extracellular volume (ECV) data acquired from preoperative contrast-enhanced CT scans.

Gastroparesis is a chronic gastrointestinal motility disorder defined by objectively delayed gastric emptying of solids in the absence of mechanical obstruction. It presents as a syndrome marked by a range of upper GI symptoms, most commonly nausea, vomiting, early satiety, bloating, belching, and upper abdominal discomfort or pain. Pylorus targeting approaches have been a common management for gastroparesis, with gastric peroral endoscopic myotomy (G-POEM) and pyloroplasty being effective surgical options. However, comparative data on redo procedure rates and outcomes remain limited.

Low serum insulin-like growth factor 1 (IGF-1) level is associated with shorter overall survival (OS) in patients with advanced unresectable hepatocellular carcinoma (HCC). This study aimed to evaluate whether preoperative IGF-1 levels are associated with OS and recurrence-free survival (RFS) in patients with HCC who underwent hepatectomy.

Establishing an anastomosis after an extended left hemicolectomy can be challenging due to insufficient colonic reach. Surgical options include the Deloyers technique (DT) and the retroileal window technique (RIWT). The primary objective was to compare the safety and functional outcomes of these restorative techniques.

With the increasing use of minimally invasive techniques and recovery protocols, hiatal hernia repair is increasingly performed with a same-day discharge (SDD) approach. This study aimed to identify factors affecting patient selection for SDD at a tertiary center and compare the outcomes of SDD with extended observation stay (EOS) after robotic hiatal hernia repair.
