Ultrasound Augmented Laparoscopy

The advancement of video technology has allowed laparoscopy to become one of the most widely used minimally invasive surgical approaches, in which surgeons attempt surgical procedures through small incisions. While a miniaturized camera inserted through one of these incisions provides real-time visual feedback into the patients’ body cavity, long, slender instruments inserted through other small incisions provide means to treat critical surgical targets. However, although a laparoscopic approach is preferred over an open surgical approach in many procedures, due to the significantly lower patient morbidity and improved recovery time (Bonjer et al. 2015), it is very challenging both cognitively and physically even for experienced surgeons. This is partly due to the dislocation of the surgeons’ perception from the action site and partly due to limitations in the conventional setup, such as limited dexterity in manipulation and limited depth perception in 2D displays. The invention of robotic surgical systems, such as the da Vinci, has solved most of the ergonomic and manipulation issues, while the stereo-display systems have eliminated most of the issues in depth perception.
Abdominal and Genitourinary Trauma
Ian Greaves, Keith Porter, Jeff Garner in Trauma Care Manual, 2021
Laparoscopy is a minimally invasive surgical technique that has gained favour in all abdominal surgery disciplines in the last 40 years. Laparoscopy in trauma has been used for many years and there are case reports of laparoscopic management of a variety of injuries. Broad consensus limits the use of laparoscopy to the following: Diagnostic surgery to identify peritoneal breach in penetrating traumaExamination for bowel perforation or serosal damage (when performed by surgeons with the appropriate skills)The management of diaphragmatic injuries where diagnosis and treatment can be undertaken laparoscopically54, 55

Robot-assisted laparoscopy is a common minimally invasive surgery performed by a surgeon who controls a specialized robot. Similar to conventional laparoscopy, small incisions are made, and the robotic manipulators and endoscopic camera are inserted into the patient. Surgical robots, such as the da VinciTM surgical system (dVSS, Intuitive Surgical Inc., Sunnyvale, CA), have specialized features such as an ergonomically designed surgeon’s console, interactive robotic arms, high-resolution 3D endoscope, and wrist-like master controls (Moorthy et al. 2004). These features give the surgical robot distinct advantages over traditional laparoscopy, such as reduced surgeon fatigue, enhanced view, larger range of motion, tremor cancellation, and scaled motion (D’Annibale et al. 2004; Hernandez et al. 2004; Moorthy et al. 2004).

To overcome all these deficiencies faced by surgeons and patients, a new surgical technique was introduced in the late 19th century, namely laparoscopy, which was a game-changer in the entire surgical domain. Laparoscopy is a minimally invasive surgery that requires multiple small incisions of the order 5–10 mm, instead of broader cuts of sizes 150–200 mm in case of open surgeries. In order to have a clear view of internal organs, the abdomen of the patient is inflated by pumping an inert gas, like carbon dioxide (CO2). CO2 has a high diffusion coefficient, non-flammable, and colorless. Hence, it is typically used for insufflation (capnoperitoneum) in minimally invasive surgeries like arthroscopy, endoscopy, and laparoscopy. It can also be rapidly cleared from the body as it is a natural metabolic end product and can reduce the risk of complications after venous embolism. Laparoscopy is used in the case of major surgeries such as removal of stones from kidney and gall bladder, removal of the gall bladder, cutting appendices, cancerous tissue resection, and many more (Tung et al. 2015).

The institutional review board (University of Health Sciences, Tepecik Education and Research Hospital, Turkey, March 13, 2019) approved the study (Approval no. 2019/4-27). SPSS version 21 software (IBM Corp., Armonk, NY) was used for statistical analyses. Continuous variables were described as means and standard deviations and categorical variables were described as frequencies and percentages. The one-way ANOVA and the chi-square test were used to detect differences among groups. The correlation of BMI with domains of EORTC QLQ-C30 and FSFI were determined using Spearmen correlation coefficients. Multiple linear regression analyses were performed to assess the effects of clinicodemographic variables and BMI on EORTC QLQ-C30 and FSFI domains. Age, marital status, monthly income, time since last treatment, surgical approach, adjuvant treatment (radiotherapy and chemotherapy) were the main confounding variables, according to a previously published review (Smits et al. 2015). Marital status was categorised as married or unmarried (single, widowed or divorced). Monthly income was divided into categories according to the national minimum wage (NMW) and classified as low (≤US$422 = NMW), middle (US$422–US$844), and high (≥US$844). The surgical approach was categorised as laparotomy or laparoscopy. The significance threshold was set to .05 for all analyses.
Advances in minimally invasive surgery and clinical measurement

With the continuous development of science, technology and improvement of people's living standards, the requirements for differentiated medical care, treatment quality and quality of life are gradually improved. People not only care about the treatment results, but also the comfort, privacy protection and minimally invasive during the treatment. Thus, minimally invasive surgery (MIS) techniques have achieved significant improvement in recent years. In MIS, doctors use a variety of techniques to operate with less damage to the body than with open surgery. In general, MIS is associated with less pain, a shorter time to be hospitalized and fewer complications than conventional techniques. Robotic surgery is one of the most typical MIS types, which provides a magnified, 3 D view of the surgical site and helps the surgeon operate with precision, flexibility and control. Another typical MIS type is laparoscopy – surgery is done through one or more small incisions, using small tubes and tiny cameras and surgical instruments. Other typical MIS types include endoscopic surgery, interventional surgery, etc. Nevertheless, image processing and signal processing are important for the surgery-related and clinical application. Novel clinical measurement and advanced signal processing methods are important or even essential in the clinic. In this supplement issue, researchers have addressed the recent technology advances in MIS, surgery technology, clinical measurement, device development, modeling and signal processing.
