Robotic liver surgery is experiencing a period of great development, but some hurdles still need to be overcome. Parenchymal transection remains one of the most technically challenging steps. The lack of dedicated instruments and the flourishing of several techniques didn't allow surgeons to reach a standard technique so far.

The surgical management of hepatic metastases from colorectal cancer may range from segmental resections to major or extended hepatectomies. The aim is to achieve complete removal of metastatic lesions while preserving adequate liver function. We present the case of a 42-year-old male patient with a history of glucose intolerance who presented with altered bowel movements and abdominal pain.

Surgeons in training have a limited opportunity to practice their skills in a realistic surgical environment. Surgical training models are expensive and are often single-use exercises involving consumable supplies. The goal of the work presented in this paper is to increase surgeon training time by developing a surgical training simulator that is portable, inexpensive, and offers a realistic surgical environment.

Laparoscopic sleeve gastrectomy is a restrictive surgery that aims to decrease the gastric volume of the patient. This study hypothesized that a higher resected gastric volume to the number of fired staplers ratio is associated with improved postoperative 12th-month outcomes. To analyze the effects of resected gastric volume to the number of fired staplers ratio on postoperative results in patients who underwent sleeve gastrectomy.

Despite the benefits of minimally invasive surgery, interventions such as laparoscopic liver surgery present unique challenges, like the significant anatomical differences between preoperative images and intraoperative scenes due to pneumoperitoneum, patient pose, and organ manipulation by surgical instruments. To address these challenges, a method for intraoperative three-dimensional reconstruction of the surgical scene, including vessels and tumors, without altering the surgical workflow, is proposed. The technique combines neural radiance field reconstructions from tracked laparoscopic videos with ultrasound three-dimensional compounding.
