Abstract Background The purpose of this study was to investigate the clinical effect of minimally invasive surgery for inguinal cryptorchidism. Methods The patients were divided into the minimally invasive surgery group (n = 100) and the traditional surgery group (n = 58). In the minimally invasive surgery group, patients with low inguinal cryptorchidism (n = 54) underwent surgery with a transscrotal incision, and patients with high inguinal cryptorchidism (n = 46) underwent laparoscopic surgery. Results There was no difference in the hospital stay duration or cost between the minimally invasive surgery group and the traditional surgery group (P > 0.05). As for the operative time, minimally invasive surgery of low inguinal cryptorchidism was shorter than traditional surgery (P = 0.033), while minimally invasive surgery of high inguinal cryptorchidism was comparable to traditional surgery (P = 0.658). Additionally, there were no cases of testicular atrophy, testicular retraction, inguinal hernia or hydrocele in either group. There was no significant difference in the incidence of poor wound healing between the two groups (P > 0.05). Although there was no significant difference in the incidence of scrotal hematoma between the two groups (P > 0.05), the incidence in the minimally invasive surgery group was higher than that in the traditional surgery group. Conclusions Minimally invasive surgery including a transscrotal incision for low inguinal cryptorchidism and laparoscopic surgery for high inguinal cryptorchidism is as safe and effective as traditional surgery, and could also provide a good cosmetic effect for children.

Localization And Mapping

Minimally invasive surgery is widely used because of its tremendous benefits to the patient. However, there are some challenges that surgeons face in this type of surgery, the most important of which is the narrow field of view. Therefore, we propose an approach to expand the field of view for minimally invasive surgery to enhance surgeons’ experience. It combines multiple views in real-time to produce a dynamic expanded view. The proposed approach extends the monocular Oriented features from an accelerated segment test and Rotated Binary robust independent elementary features—Simultaneous Localization And Mapping (ORB-SLAM) to work with a multi-camera setup. The ORB-SLAM’s three parallel threads, namely tracking, mapping and loop closing, are performed for each camera and new threads are added to calculate the relative cameras’ pose and to construct the expanded view. A new algorithm for estimating the optimal inter-camera correspondence matrix from a set of corresponding 3D map points is presented. This optimal transformation is then used to produce the final view. The proposed approach was evaluated using both human models and in vivo data. The evaluation results of the proposed correspondence matrix estimation algorithm prove its ability to reduce the error and to produce an accurate transformation. The results also show that when other approaches fail, the proposed approach can produce an expanded view. In this work, a real-time dynamic field-of-view expansion approach that can work in all situations regardless of images’ overlap is proposed. It outperforms the previous approaches and can also work at 21 fps.

Background: Abdominal cavity irrigation is a more minimally invasive surgery than that using a gas. Minimally invasive surgery improves the quality of life of patients; however, it demands higher skills from the doctors. Therefore, the study aimed to reduce the burden by assisting and automating the hemostatic procedure a highly frequent procedure by taking advantage of the clearness of the endoscopic images and continuous bleeding point observations in the liquid. We aimed to construct a method for detecting organs, bleeding sites, and hemostasis regions.Methods: We developed a method to perform real-time detection based on machine learning using laparoscopic videos. Our training dataset was prepared from three experiments in pigs. Linear support vector machine was applied using new color feature descriptors. In the verification of the accuracy of the classifier, we performed five-part cross-validation. Classification processing time was measured to verify the real-time property. Furthermore, we visualized the time series class change of the surgical field during the hemostatic procedure.Results: The accuracy of our classifier was 98.3% and the processing cost to perform real-time was enough. Furthermore, it was conceivable to quantitatively indicate the completion of the hemostatic procedure based on the changes in the bleeding region by ablation and the hemostasis regions by tissue coagulation.Conclusions: The organs, bleeding sites, and hemostasis regions classification was useful for assisting and automating the hemostatic procedure in the liquid. Our method can be adapted to more hemostatic procedures.

Sacral Resection

Resection of large presacral schwannomas can present a challenge. The posterior approach is commonly associated with coccygeal disarticulation, partial sacral resection, and muscular disarticulation, which can all result in significant morbidity. Minimally invasive surgery may obviate some of the morbidity traditionally associated with this approach. The authors present the case of a morbidly obese 49-year-old man with an enlarging presacral schwannoma. The patient refused laparoscopic resection because of the morbidity he had experienced with a previous laparoscopic surgery. The tumor was resected using a minimally invasive paracoccygeal approach, which affords improved access with minimal morbidity.

Over the last two decades, minimally invasive surgery (MIS) has become the mainstream method for the treatment of many abdominal diseases previously treated by open surgery. It has resulted in improvements in many outcomes during and after surgery. The Royal College of Surgeons of England has always played an active role in training both consultant surgeons and trainees in minimally invasive surgery with courses such as the Intercollegiate Basic Surgical Skills Courses (BSS) and laparoscopic cholecystectomy courses run in the College itself and in regional units. Laparoscopic surgery itself presents unique challenges that demand that courses be designed specifically with these in mind.

Surgical Skill

Minimally invasive surgery accelerates postoperative recovery, but can only be applied by surgeons having advanced conduct skills. We developed a master-slave manipulator, i.e., robotic forceps for laparoscopic surgery that enhances surgical skill. Robotic forceps consists of a master-slave manipulator, a support component, a controller, an operating conditions display, and a foot switch for changing operating conditions. This paper details specifications and components of robotic forceps and evaluates conductance, such as measurement of the slave hand’s grip and suturing and ligaturing, conducted on a sponge stomach model. A comparison of support function in experiments demonstrates their effectiveness.

Tissue Trauma

Minimally invasive surgery (MIS) or laparoscopic surgery has changed the focus of surgery and has become an alternative to open surgical procedures. Operations are performed through small incisions in the abdomen thus avoiding the need for large incisions. This results in less tissue trauma, less scarring, and faster post-operative recovery time. However, the inherent challenges of laparoscopic procedures include limited visibility, constrained working space and the need for advanced surgical tools to safely and efficiently perform the surgical procedure. It is also necessary for surgeons to obtain advanced surgical training to perform these procedures.
