Augmented Reality Combined with Fluorescence Imaging Enhances Laparoscopic Segmentectomy for Hepatocellular Carcinoma

Augmented reality combined with indocyanine green fluorescence imaging guided laparoscopic segmentectomy for hepatocellular carcinoma significantly reduces intraoperative blood loss, decreases remnant liver ischemia, and improves disease-free survival rates at 1 and 3 years. This technology provides a standardized approach for liver parenchyma section and shows promising clinical application prospects.

Conditional survival rates and probabilities of death in patients with exocrine pancreatic cancer

Survival rates and probabilities of death in patients with exocrine pancreatic cancer (EPC) were investigated in a population-based study. The study found that the overall 5-year relative survival rate at diagnosis for pancreatic ductal adenocarcinoma (PDAC) was 8.5%. Among PDAC patients who survived for 2 years, the 3-year conditional survival rate was 50.1%, and among those who survived for 5 years, the 5-year conditional survival rate was 77.6%. The study also revealed that elderly patients with localized or regional-stage PDAC who underwent surgery had comparable conditional survival rates to younger patients.

Primary tumor resection does not impact event-free survival in patients with metastatic small bowel neuroendocrine tumors

The study investigated the impact of primary tumor resection on the development of disease-specific complications in patients with metastatic well-differentiated small bowel neuroendocrine tumors (SBNETs). The retrospective analysis of 180 patients showed that rates of event-free survival did not differ based on primary tumor management. Patients who underwent medical management first had a 23% complication rate leading to surgery, compared to a 28% rate in surgically treated patients. The development of a primary tumor obstruction did not worsen outcomes, but ongoing tumor progression requiring a second surgery was associated with higher mortality.

Comparison of Single-Port and Multi-Port Robotic Total Mesorectal Excision for Rectal Cancer: Similar Efficacy and Safety

Single-port robotic total mesorectal excision is comparable to multi-port robotic total mesorectal excision in terms of short-term clinical outcomes for rectal cancer treatment. A retrospective study of 128 patients found that the single-port system resulted in shorter operative times, smaller incision length, and shorter hospital stays. C-reactive protein levels were also lower in the single-port group. Both groups had similar rates of postoperative complications, with only slight differences in anastomotic leakage and positive circumferential resection margins. The study suggests that the single-port robot can be considered a surgical option for rectal cancer treatment.

Primary Surgeon Specialty Does Not Impact Postoperative Complications in Esophagectomy

Cardiothoracic surgeons and general surgeons perform the majority of esophagectomies, but differences in surgical techniques exist. This study analyzed data from 3,247 patients and found that cardiothoracic surgeons were more likely to use traditional minimally invasive or open approaches, while general surgeons favored robotic or hybrid approaches. However, after adjusting for risk factors, there were no significant differences in postoperative complications between the two specialties. The study suggests that esophagectomy can be performed safely by surgeons with different specialties and training pathways.

The Kono-S Anastomosis Shows Low Complication Rates and Promising Long-Term Results in Crohn’s Disease Patients

In a multicenter study, 262 consecutive patients with Crohn’s disease underwent Kono-S anastomosis. The study reported very low rates of anastomotic failure (1.5%), reoperation (0.7%), and postoperative surgical site infection (6.1%). After a median follow-up of 49.4 months, surgical recurrence was found in 7.6% of patients. Perianal disease, urgent/emergent surgery, and postoperative use of steroids were associated with an increased risk of overall recurrence. The findings confirm the safety and efficacy of the Kono-S anastomosis as a technique for long-term outcomes in Crohn’s disease.

Timing of EUS-Guided Drainage for Postoperative Pancreatic Fluid Collections

Early endoscopic ultrasound (EUS)-guided drainage can effectively manage postoperative pancreatic fluid collections (POPFCs) without increasing adverse events. Six retrospective studies involving 128 and 107 patients were analyzed, with the threshold for early and delayed drainage ranging from 14 to 30 days. Distal pancreatectomy was the main cause of POPFCs. The pooled odds ratio for adverse events was 0.81, indicating no significant difference between early and delayed drainage. There were no procedure-related mortalities, and technical success was achieved in all cases.

Low inter-rater reliability and variability in assessing laparoscopic fundoplication with endoscopy

This study evaluated the inter-rater reliability and variability in assessing laparoscopic fundoplication using endoscopy. A total of 101 participants, including upper gastrointestinal surgeons and gastroenterologists, analyzed ten static endoscopic images post-fundoplication. The study found that overall accuracy was 76% for upper gastrointestinal surgeons and 69.9% for gastroenterologists. Upper gastrointestinal surgeons performed significantly better in certain cases, particularly in describing the integrity of the fundoplication. The study highlights the need for a standardized reporting system to improve consistency and reliability in assessing post-fundoplication patients.

Long-term outcomes of ultrasound-guided thermal ablation for low-risk papillary thyroid microcarcinoma

A multicenter retrospective study reports that ultrasound-guided thermal ablation (TA) is an effective and safe treatment option for patients with solitary low-risk papillary thyroid microcarcinoma (PTMC). Over a median follow-up period of 77.2 months, the incidence of disease progression, lymph node metastasis, and recurrent tumors were 3.6%, 1.1%, and 2.5%, respectively. TA achieved a median volume reduction rate of 100% and 471 tumors disappeared radiographically. Complications were minimal and transient. The study found no significant differences in outcomes between radiofrequency ablation and microwave ablation subgroups.

Female Surgeons Linked to Lower Healthcare Costs for Common Surgical Procedures

Female surgeons are associated with lower healthcare costs compared to male surgeons for patients undergoing common surgical procedures, according to a population-based study in Ontario, Canada. The study found that patients treated by male surgeons had higher healthcare costs at 30 days, 90 days, and 1 year after surgery compared to those treated by female surgeons. These findings highlight the importance of creating inclusive environments and policies to support women surgeons.
