Article Abstract
Purpose: Single-incision laparoscopic surgery (SILS) for colon cancer is technically challenging for novice surgeons. Although it has been shown to be safe and feasible, the learning curve (LC) among novices has not been characterized. The present study investigated the LC for SILS based on data from several novice surgeons.
Methods: We retrospectively reviewed consecutive cases of SILS-ileocecal resection (SILS-ICR) performed by two experienced and three novice surgeons from May 2009 to March 2020. A cumulative sum (CUSUM) analysis was used to analyze the learning curve and evaluate SILS completion. In addition, a statistical model was created to clarify the difference between the operation times of novices (Surgeons C, D, and E) and experienced surgeons (Surgeons A and B), estimating the operative time and risk estimation model.
Results: Two experienced surgeons and three novice surgeons performed 187 and 103 SILS-ICRs, respectively. A CUSUM analysis showed LCs of 20, 18, and 20 cases for Surgeons C, D, and E, respectively, suggesting that novice surgeons would achieve results comparable to those of experienced surgeons in 39, 47, and 36 cases, respectively.
Conclusions: In SILS-ICR, novice surgeons reached the nadir in 18-20 cases and reached the level of experienced surgeons in 36-47 cases.

Purpose: The potential of mixed reality to improve the accuracy of glenoid preparation pin positioning in shoulder arthroplasty has been previously reported. Another benefit of mixed reality may be its ability to assist junior surgeons in enhancing their precision during prosthetic procedures. The aim of this study was to evaluate and compare the accuracy of glenoid preparation pin positioning between a senior surgeon and a junior surgeon utilizing mixed reality guidance.

Vascular surgical site infections (SSI) are common and associated with graft infection, surgical reintervention, and increased lengths of stay. While antibiotic prophylaxis and negative pressure dressings have improved SSI rates, reported incidence remains as high as 30%. Robotic approaches have decreased surgical site infections in multiple surgical specialties, but remain without a vascular surgery indication.

This paper proposes a novel virtual-fixtures-based shared control concept for eye surgery systems focusing on cataract procedures, one of the most common ophthalmic surgeries. Current research on haptic force feedback aims to enhance manipulation capabilities by integrating teleoperated medical robots. Our proposed concept utilizes teleoperated medical robots to improve the training of young surgeons by providing haptic feedback during cataract operations based on geometrical virtual fixtures.

Introduction: Minimally-invasive partial nephrectomy (MIPN) is the standard treatment for kidney tumors with a diameter smaller than 4 cm. It is also performed in selected cases of tumors reaching 7 cm, but it may lead to potential complications. We investigated the current literature for simulators that could be used to teach urologists alone or within the boundaries of a course or a curriculum.
