RESUMEN
BACKGROUND: Surgical care significantly contributes to healthcare-associated greenhouse gas emissions (GHG). Surgeon attitudes about mitigation of the impact of surgical practice on environmental sustainability remains poorly understood. To better understand surgeon perspectives globally, the Society of American Gastrointestinal and Endoscopic Surgeons and the European Association for Endoscopic Surgery established a joint Sustainability in Surgical Practice (SSP) Task Force and distributed a survey on sustainability. METHODS: Our survey asked about (1) surgeon attitudes toward sustainability, (2) ability to estimate the carbon footprint of surgical procedures and supplies, (3) concerns about the negative impacts of sustainable interventions, (4) willingness to change specific practices, and (5) preferred educational topics and modalities. Questions were primarily written in Likert-scale format. A clustering analysis was performed to determine whether survey respondents could be grouped into distinct subsets to inform future outreach and education efforts. RESULTS: We received 1024 responses, predominantly from North America and Europe. The study revealed that while 63% of respondents were motivated to enhance the sustainability of their practice, less than 10% could accurately estimate the carbon footprint of surgical activities. Most were not concerned that sustainability efforts would negatively impact their practice and showed readiness to adopt proposed sustainable practices. Online webinars and modules were the preferred educational methods. A clustering analysis identified a group particularly concerned yet willing to adopt sustainable changes. CONCLUSION: Surgeons believe that operating room waste is a critical issue and are willing to change practice to improve it. However, there exists a gap in understanding the environmental impact of surgical procedures and supplies, and a sizable minority have some degree of concern about potential adverse consequences of implementing sustainable policies. This study uniquely provides an international, multidisciplinary snapshot of surgeons' attitudes, knowledge, concerns, willingness, and preferred educational modalities related to mitigating the environmental impact of surgical practice.
RESUMEN
BACKGROUND: The healthcare system plays a pivotal role in environmental sustainability, and the operating room (OR) significantly contributes to its overall carbon footprint. In response to this critical challenge, leading medical societies, government bodies, regulatory agencies, and industry stakeholders are taking measures to address healthcare sustainability and its impact on climate change. Healthcare now represents almost 20% of the US national economy and 8.5% of US carbon emissions. Internationally, healthcare represents 5% of global carbon emissions. US Healthcare is an outlier in both per capita cost, and per capita greenhouse gas emission, with almost twice per capita emissions compared to every other country in the world. METHODS: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and the European Association for Endoscopic Surgery (EAES) established the Sustainability in Surgical Practice joint task force in 2023. This collaborative effort aims to actively promote education, mitigation, and innovation, steering surgical practices toward a more sustainable future. RESULTS: Several key initiatives have included a survey of members' knowledge and awareness, a scoping review of terminology, metrics, and initiatives, and deep engagement of key stakeholders. DISCUSSION: This position paper serves as a Call to Action, proposing a series of actions to catalyze and accelerate the surgical sustainability leadership needed to respond effectively to climate change, and to lead the societal transformation towards health that our times demand.

BACKGROUND: We conducted a systematic review and meta-analysis to evaluate the role of High Energy Devices (HEDs) versus conventional clamp and tie technique in thyroidectomy. This work is endorsed by the Italian Society of Surgical Endoscopy (Italian Society of Endoscopic Surgery and new technologies-SICE) in the broader project on the evaluation of the role of HEDs in different surgical settings with the full health technology assessment report. MEHODS: Inclusion criteria were adult patients (≥ 18 years old) undergoing Thyroidectomy/Parathyroidectomy conducted with High Energy Devices (as ultrasonic (US), radiofrequency (RF), and hybrid energy (H-US/RF)) in the setting of thyroid surgery (both partial and total) for benign and malign diseases. However, some variability was found in included studies and described in the text. This systematic review and meta-analysis were performed according to the Cochrane handbook for systematic reviews, and the recommendations of the 2020 updated Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) guidelines were pursuit. Selection of abstracts was performed in Ryyan system by 2 independent reviewers, and doubts were solved by another independent reviewer. At the end of literature research, Randomized controlled trials and observational studies were included. Risk of Bias was assessed with ROB2 for RCTs, and New Castle Ottawa Scale for Observational studies. RESULTS: The literature search yielded 47 studies, including 29 RCTs and 18 observational studies. Meta-analysis was performed for 29 randomized clinical trials. Outcomes included in the comparison between High Energy Devise and conventional technique groups were operative time, operative blood loss, overall post-operative drainage volume, length of stay, complications, and costs. HED significantly reduced operative time (28 studies, 3097patients; MD -128.8; 95% CI -34.4 to -23.20; I2 = 96%, p < 0.00001, Random-effect), intra-operative blood loss (13 studies, 642 vs 519 patients; SMD -0.82; 95% CI -1.33 to -0.32; I2 = 93%, p < 0.00001, Random-effect), LOS (22 studies, 2808 vs 2789 patients; MD -0.38, 95% CI -0.59 to -0.17; I2 = 98%, p < 0.00001 Random-effect), and healthcare costs (8 studies, 1138 vs 1129 patients, SMD 1.05; 95% CI -0.06 to 2.16; I2 = 99%, p < 0.00001 Random-effect). The rate of overall intraoperative complications was significantly different between both groups (25 studies, 2804 vs 2775 patients; RR 0.88, 95% CI 0.80 to 0.97; I2 = 38%, p = 0.03 Random-effect), but the sensitivity analysis did not find a statistically significant difference (6 studies, 605 vs 594 patients, RR; 95% CI to; I2 = 0%, p = 0.50, Random-effect). There was no difference in the subgroup analysis for the occurrence of transient and permanent RLN palsy, nor hematoma formation and hypocalcaemia. DISCUSSION: Though findings of our systematic review and metanalysis are limited by heterogeneous data, surgeons, hospital managers, and policymakers should note that the use of High Energy Devices compared to conventional clamp and tie technique have reduced operative times, intra-operative blood loss, length of stay, and hospital costs in patients underwent to tyroid surgery. Future work must explore issues of equity to mitigate barriers to patient access to safe thyroid surgical care and define better this initial results.

INTRODUCTION: As life expectancy has been increasing, older patients are becoming more central to the healthcare system, leading to more intensive care use and longer hospital stays. Nevertheless, advancements in minimally invasive surgical techniques offer safe and effective options for older patients with colorectal diseases. This study aims to provide comprehensive evidence on the role of minimally invasive surgery in treating colorectal diseases in older patients. MATERIAL AND METHODS: All articles directly compared the minimally invasive approach with open surgery in patients aged ≥65 years. The present metanalysis took 30-day complications as primary outcomes. Length of hospital stay, readmission, and 30-day mortality were also assessed, as secondary outcomes. Further subgroup analyses were carried out based on surgery setting, lesion features, and location. RESULTS: After searching the main databases, 84 articles were included. Evaluation of 30-day complications rate, length of hospital stay, and 30-day mortality significantly favored minimally invasive approaches. The outcome readmission did not show any significant difference. CONCLUSIONS: The current metanalysis demonstrates clear advantages of minimally invasive techniques over open surgery in colorectal procedures for older patients, particularly in reducing complications, mortality, and hospitalization. This suggests that prioritizing these techniques, based on available expertise and facilities, could improve outcomes and quality of care for older patients undergoing colorectal surgery.
RESUMEN
BACKGROUND: As the population ages, more older adults are presenting for surgery. Age-related declines in physiological reserve and functional capacity can result in frailty and poor outcomes after surgery. Hence, optimizing perioperative care in older patients is imperative. Enhanced Recovery After Surgery (ERAS) pathways and Minimally Invasive Surgery (MIS) may influence surgical outcomes, but current use and impact on older adults patients is unknown. The aim of this study was to provide evidence-based recommendations on perioperative care of older adults undergoing major abdominal surgery. METHODS: Expert consensus determined working definitions for key terms and metrics related to perioperative care. A systematic literature review and meta-analysis was performed using the PubMed, Embase, Cochrane Library, and Clinicaltrials.gov databases for 24 pre-defined key questions in the topic areas of prehabilitation, MIS, and ERAS in major abdominal surgery (colorectal, upper gastrointestinal (UGI), Hernia, and hepatopancreatic biliary (HPB)) to generate evidence-based recommendations following the GRADE methodology. RESULT: Older adults were defined as 65 years and older. Over 20,000 articles were initially retrieved from search parameters. Evidence synthesis was performed across the three topic areas from 172 studies, with meta-analyses conducted for MIS and ERAS topics. The use of MIS and ERAS was recommended for older adult patients particularly when undergoing colorectal surgery. Expert opinion recommended prehabilitation, cessation of smoking and alcohol, and correction of anemia in all colorectal, UGI, Hernia, and HPB procedures in older adults. All recommendations were conditional, with low to very low certainty of evidence, with the exception of ERAS program in colorectal surgery. CONCLUSIONS: MIS and ERAS are recommended in older adults undergoing major abdominal surgery, with evidence supporting use in colorectal surgery. Though expert opinion supported prehabilitation, there is insufficient evidence supporting use. This work has identified evidence gaps for further studies to optimize older adults undergoing major abdominal surgery.

Hospitals in Europe produce approximately 6 million tons of medical waste annually, about one-third of this originating in operating rooms. Most of it is solid waste, which can be recycled if bodily fluids do not contaminate it. Only 2-3% of hospital waste must be disposed of as infectious waste, and this is much lower than the 50-70% of garbage in the biohazard waste stream. In June 2021, at the main operating room of the Department of General Surgery of the University of Turin, we began a separate collection program for materials consisting of plastic, paper, TNT (material not contaminated by bodily fluids), and biohazardous waste. We calculated the number of boxes and the weight of special waste disposed produced every month in one operating room for 18 months. The monthly number of Sanibox and the monthly weight of biohazardous waste decreased during the observation period. The reduction trend was not constant but showed variations during the 18 months. Direct proportionality between number of low-complexity procedures and production of biohazardous waste was found (p = 0.050). We observed an optimization in the collection and filling of plastic, paper and TNT boxes separated and sent for recycling. One of the barriers to recycling hospital waste, and surgical waste in particular, is the failure to separate infectious waste from clean waste. A careful separate collection of waste in the operating room is the first step in reducing environmental pollution and management costs for the disposal of hospital waste.
RESUMEN
Surgeons performing robotic-assisted laparoscopic surgery experience physical stress and overuse of shoulder muscles due to sub-optimal arm support during surgery. The objective is to present a novel design and prototype of a dynamic arm support for robotic laparoscopic surgery to evaluate its ergonomics and performance on the AdLap-VR simulation training device. The prototype was designed using the mechanical engineering design process: Technical requirements, concept creation, concept selection, 3D-design and built of the prototype. A crossover study was performed on a marble sorting task on the AdLap-VR. The first group performed four trials without the arm support, followed by four trials with the arm support, and the other group executed the sequence vice versa. The performance parameters used were time to complete (s), path length (mm), and the number of collisions. Afterward, the participants filled out a questionnaire on the ergonomic experience regarding both situations. 20 students executed 160 performed trials on the AdLap-VR Significant decreases in the subjective comfort parameters mental demand, physical demand, effort and frustration were observed as a result of introducing the novel arm support. Significant decreases in the objective performance parameters path length and the number of collisions were also observed during the tests. The newly developed dynamic arm support was found to improve comfort and enhance performance through increased stability on the robotic surgery skills simulator AdLap-VR.

PURPOSE: Emergency treatment of acute diverticulitis remains a hazy field. Despite a number of clinical studies, randomized controlled trials (RCTs), guidelines and surgical societies recommendations, the most critical hot topics have yet to be addressed. METHODS: Literature research from 1963 until today was performed. Data regarding the principal RCTs and observational studies were summarized in descriptive tables. In particular we aimed to focus on the following topics: the role of laparoscopy, the acute care setting, the RCTs, guidelines, observational studies and classifications proposed by literature, the problem in case of a pandemic, and the importance of adapting treatment /place/surgeon conditions. RESULTS: In the evaluation of these points we did not try to find any prospective evolution of the concepts achievements. On the contrary we simply report the individuals strands of research from a retrospective point of view, similarly to what Steve Jobes said: "you can't connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future". We have finally obtained what can be defined "a narrative review of the literature on diverticulitis". CONCLUSIONS: Not only evidence-based medicine but also the contextualization, as also the role of 'competent' surgeons, should guide to novel approach in acute diverticulitis management.

The Human Machine Interface (HMI) of intraluminal robots has a crucial impact on the clinician's performance. It increases or decreases the difficulty of the tasks, and is connected to the users' physical and mental stress. OBJECTIVE: This article presents a framework to compare and evaluate different HMIs for robotic colonoscopy, with the objective of identifying the optimal HMI that minimises the clinician's effort and maximises the clinical outcomes. METHODS: The framework comprises a 1) a virtual simulator (clinically validated), 2) wearable sensors measuring the cognitive load, 3) a data collection unit of metrics correlated to the clinical performance, and 4) questionnaires exploring the users' impressions and perceived stress. The framework was tested with 42 clinicians investigating the optimal device for tele-operated control of robotic colonoscopes. Two control devices were selected and compared: a haptic serial-kinematic device and a standard videogame joypad. RESULTS: The haptic device was preferred by the endoscopists, but the joypad enabled better clinical performance and reduced cognitive and physical load. CONCLUSION: The framework can be used to evaluate different aspects of a HMI, both hardware and software, and determine the optimal HMI that can reduce the burden on clinicians while improving the clinical outcome. SIGNIFICANCE: The findings of this study, and of future studies performed with this framework, can inform the design and development of HMIs for intraluminal robots, leading to improved clinical performance, reduced physical and mental stress for clinicians, and ultimately better patient outcomes.

AIMS: The identification of the anatomical components of the Calot's Triangle during laparoscopic cholecystectomy (LC) might be challenging and its difficulty may increase when a surgical trainee (ST) is in charge, ultimately allegedly affecting also the incidence of common bile duct injuries (CBDIs). There are various methods to help reach the critical view of safety (CVS): intraoperative cholangiogram (IOC), critical view of safety in white light (CVS-WL) and near-infrared fluorescent cholangiography (NIRF-C). The primary objective was to compare the use of these techniques to obtain the CVS during elective LC performed by ST. METHODS: This was a multicentre prospective observational study (Clinicalstrials.gov Registration number: NCT04863482). The impact of three different visualization techniques (IOC, CVS-WL, NIRF-C) on LC was analyzed. Operative time and time to achieve the CVS were considered. All the participating surgeons were also required to fill in three questionnaires at the end of the operation focusing on anatomical identification of the general task and their satisfaction. RESULTS: Twenty-nine centers participated for a total of 338 patients: 260 CVS-WL, 10 IOC and 68 NIRF-C groups. The groups did not differ in the baseline characteristics. CVS was considered achieved in all the included case. Rates were statistically higher in the NIR-C group for common hepatic and common bile duct visualization (p = 0.046; p < 0.005, respectively). There were no statistically significant differences in operative time (p = 0.089) nor in the time to achieve the CVS (p = 0.626). Three biliary duct injuries were reported: 2 in the CVS-WL and 1 in the NIR-C. Surgical workload scores were statistically lower in every domain in the NIR-C group. Subjective satisfaction was higher in the NIR-C group. There were no other statistically significant differences. CONCLUSIONS: These data showed that using NIRF-C did not prolong operative time but positively influenced the surgeon's satisfaction of the performance of LC.

BACKGROUND: During minimal access surgery, surgical smoke is produced which can potentially be inhaled by the surgical team, leading to several health risks. This smoke can escape from the abdominal cavity into the operating room due to trocar leakage. The trocars and insufflator that are used during surgery influence gas leakage. Therefore, this study compares particle escape from a valveless (Conmed AirSeal iFS), and a conventional (Karl Storz Endoflator) system. MATERIALS AND METHODS: Using an in vitro model, a conventional and a valveless trocar system were compared. A protocol that simulated various surgical phases was defined to assess the surgical conditions and particle leakage. Insufflation pressures and instrument diameters were varied as these are known to affect gas leakage. RESULTS: The conventional trocar leaked during two distinct phases. Removal of the obturator caused a sudden release of particles. During instrument insertion, an average of 211 (IQR 111) particles per second escaped when using the 5 mm diameter instrument. With the 10 mm instrument, 50 (IQR 13) particles per second were measured. With the conventional trocar, a higher abdominal pressure increased particle leakage. The valveless trocar demonstrated a continuously high particle release during all phases. After the obturator was removed, particle escape increased sharply. Particle escape decreased to 1276 (IQR 580) particles per second for the 5 mm instrument insertion, and 1084 (IQR 630) particles per second for 10 mm instrument insertion. With the valveless trocar system, a higher insufflation pressure lowered particle escape. CONCLUSIONS: This study shows that a valveless trocar system releases more particles into the operating room environment than a conventional trocar. During instrument insertion, the leakage through the valveless system is 6 to 20 times higher than the conventional system. With a valveless trocar, leakage decreases with increasing pressure. With both trocar types leakage depends on instrument diameter.

BACKGROUND: During laparoscopic surgery, CO2 insufflation gas could leak from the intra-abdominal cavity into the operating theater. Medical staff could therefore be exposed to hazardous substances present in leaked gas. Although previous studies have shown that leakage through trocars is a contributing factor, trocar performance over longer periods remains unclear. This study investigates the influence of prolonged instrument manipulation on gas leakage through trocars. METHODS: Twenty-five trocars with diameters ranging from 10 to 15 mm were included in the study. An experimental model was developed to facilitate instrument manipulation in a trocar under loading. The trocar was mounted to a custom airtight container insufflated with CO2 to a pressure of 15 mmHg, similar to clinical practice. A linear stage was used for prolonged instrument manipulation. At the same time, a fixed load was applied radially to the trocar cannula to mimic the reaction force of the abdominal wall. Gas leakage was measured before, after, and during instrument manipulation. RESULTS: After instrument manipulation, leakage rates per trocar varied between 0.0 and 5.58 L/min. No large differences were found between leakage rates before and after prolonged manipulation in static and dynamic measurements. However, the prolonged instrument manipulation did cause visible damage to two trocars and revealed unintended leakage pathways in others that can be related to production flaws. CONCLUSION: Prolonged instrument manipulation did not increase gas leakage rates through trocars, despite damage to some individual trocars. Nevertheless, gas leakage through trocars occurs and is caused by different trocar-specific mechanisms and design issues.

Management of diverticular abscess (DA) is still controversial. Antibiotic therapy is indicated in abscesses ≤ 4 cm, while percutaneous drainage/surgery in abscesses > 4 cm. The study aims to assess the role of antibiotics and surgical treatments in patients affected by DA. We retrospectively analyzed 100 consecutive patients with DA between 2013 and 2020, with a minimum follow-up of 12 months. They were divided into two groups depending on abscess size ≤ or > 4 cm (group 1 and group 2, respectively). All patients were initially treated with intravenous antibiotics. Surgery was considered in patients with generalized peritonitis at admission or after the failure of antibiotic therapy. The primary endpoint was to compare recurrence rates for antibiotics and surgery. The secondary endpoint was to assess the failure rate of each antibiotic regimen resulting in surgery. In group 1, 31 (72.1%) patients were conservatively treated and 12 (27.9%) underwent surgery. In group 2, percentages were respectively 50.9% (29 patients) and 49.1% (28 patients). We observed 4 recurrences in group 1 and 6 in group 2. Recurrence required surgery in 3 patients/group. We administered amoxicillin-clavulanic acid to 74 patients, piperacillin-tazobactam to 14 patients and ciprofloxacin + metronidazole to 12 patients. All patients referred to surgery had been previously treated with amoxicillin-Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation clavulanic acid. No percutaneous drainage was performed in a hundred consecutive patients. Surgical treatment was associated with a lower risk of recurrence in patients with abscess > 4 cm, compared to antibiotics. Amoxicillin-clavulanic acid was associated with a higher therapeutic failure rate than piperacillin-tazobactam/ciprofloxacin + metronidazole.

INTRODUCTION: According to the literature, there is no clear definition of a High Energy Devices (HEDs), and their proper indications for use are also unclear. Nevertheless, the flourishing market of HEDs could make their choice in daily clinical practice arduous, possibly increasing the risk of improper use for a lack of specific training. At the same time, the diffusion of HEDs impacts the economic asset of the healthcare systems. This study aims to assess the efficacy and safety of HEDs compared to electrocautery devices while performing laparoscopic cholecystectomy (LC). MATERIALS AND METHODS: On behalf of the Italian Society of Endoscopic Surgery and New Technologies, experts performed a systematic review and meta-analysis and synthesised the evidence assessing the efficacy and safety of HEDs compared to electrocautery devices while performing laparoscopic cholecystectomy (LC). Only randomised controlled trials (RCTs) and comparative observational studies were included. Outcomes were: operating time, bleeding, intra-operative and post-operative complications, length of hospital stay, costs, and exposition to surgical smoke. The review was registered on PROSPERO (CRD42021250447). RESULTS: Twenty-six studies were included: 21 RCTs, one prospective parallel arm comparative non-RCT, and one retrospective cohort study, while three were prospective comparative studies. Most of the studies included laparoscopic cholecystectomy performed in an elective setting. All the studies but three analysed the outcomes deriving from the utilisation of US sources of energy compared to electrocautery. Operative time was significantly shorter in the HED group compared to the electrocautery group (15 studies, 1938 patients; SMD - 1.33; 95% CI - 1.89 to 0.78; I2 = 97%, Random-effect). No other statistically significant differences were found in the other examined variables. CONCLUSIONS: HEDs seem to have a superiority over Electrocautery while performing LC in terms of operative time, while no difference was observed in terms of length of hospitalisation and blood loss. No concerns about safety were raised.

AIM: The choice of whether to perform protective ileostomy (PI) after anterior resection (AR) is mainly guided by risk factors (RFs) responsible for the development of anastomotic leakage (AL). However, clear guidelines about PI creation are still lacking in the literature and this is often decided according to the surgeon's preferences, experiences or feelings. This qualitative study aims to investigate, by an open-ended question survey, the individual surgeon's decision-making process regarding PI creation after elective AR. METHOD: Fifty four colorectal surgeons took part in an electronic survey to answer the questions and describe what usually led their decision to perform PI. A content analysis was used to code the answers. To classify answers, five dichotomous categories (In favour/Against PI, Listed/Unlisted RFs, Typical/Atypical, Emotions/Non-emotions, Personal experience/No personal experience) have been developed. RESULTS: Overall, 76% of surgeons were in favour of PI creation and 88% considered listed RFs in the question of whether to perform PI. Atypical answers were reported in 10% of cases. Emotions and personal experience influenced surgeons' decision-making process in 22% and 49% of cases, respectively. The most frequently considered RFs were the distance of the anastomosis from the anal verge (96%), neoadjuvant chemoradiotherapy (88%), a positive intraoperative leak test (65%), blood loss (37%) and immunosuppression therapy (35%). CONCLUSION: The indications to perform PI following rectal cancer surgery lack standardization and evidence-based guidelines are required to inform practice. Until then, expert opinion can be helpful to assist the decision-making process in patients who have undergone AR for adenocarcinoma.

BACKGROUND: Intracorporeal (IIA) and extracorporeal anastomosis (EIA) are two well-established techniques for restoration of bowel continuity after laparoscopic right colectomy (LRC). Since no economic analysis comparing the two different anastomotic techniques has been performed yet, it is still unclear if IIA can reduce perioperative costs. The aim of the study was to compare costs of LRC with IIA or EIA for right-sided colon neoplasm. METHODS: This is a cost analysis of a single-institution double-blinded randomized controlled trial comparing the outcomes of LRC with IIA and LRC with EIA in patients with a right-sided colon neoplasm. All direct in-hospital costs related to patient's admission were recorded (intraoperative costs: operative room, surgical tools, blood units-postoperative costs: hospital stay, laboratory and microbiology analyses, diagnostic services, analgesic drugs and antibiotic therapy, blood units, reoperation-outpatient costs: post-discharge wound medications). This trial was registered with ClinicalTrials.gov, Number NCT03045107. RESULTS: A total of 140 patients were randomized and analyzed. Mean overall costs in the IIA group exceeded 349 the mean overall costs of the EIA group (7926.87 ± 4617.23 vs. 7577.45 ± 6131.17 ; P = 0.704). A mean extra charge of 608 regarding total intraoperative costs was recorded in the IIA group (3058.84 ± 897.42 vs. 2450.15 ± 558.90 ; P < 0.001). The cost of surgical instruments resulted in 542 additional charge per patient in the IIA group compared to EIA group (1782.74 ± 541.26 vs. 1240.55 ± 384.09 ; P < 0.001). The mean cost of operative room occupancy was comparable in IIA and EIA group: 1276.09 ± 514.94 vs. 1209.60 ± 422.80 (P = 0.405). No significant differences were observed in postoperative costs and in outpatient costs. CONCLUSION: This economic analysis showed that IIA and EIA after LRC had similar overall costs, even though there were intraoperative extra costs of IIA.

BACKGROUND: Clinical practice recommendations for the management of acute appendicitis in pregnancy are lacking. OBJECTIVE: To develop an evidence-informed, trustworthy guideline on the management of appendicitis in pregnancy. We aimed to address the questions of conservative or surgical management, and laparoscopic or open surgery for acute appendicitis. METHODS: We performed a systematic review, meta-analysis, and evidence appraisal using the GRADE methodology. A European, multidisciplinary panel of surgeons, obstetricians/gynecologists, a midwife, and 3 patient representatives reached consensus through an evidence-to-decision framework and a Delphi process to formulate the recommendations. The project was developed in an online authoring and publication platform (MAGICapp). RESULTS: Research evidence was of very low certainty. We recommend operative treatment over conservative management in pregnant patients with complicated appendicitis or appendicolith on imaging studies (strong recommendation). We suggest operative treatment over conservative management in pregnant patients with uncomplicated appendicitis and no appendicolith on imaging studies (weak recommendation). We suggest laparoscopic appendectomy in patients with acute appendicitis until the 20th week of gestation, or when the fundus of the uterus is below the level of the umbilicus; and laparoscopic or open appendectomy in patients with acute appendicitis beyond the 20th week of gestation, or when the fundus of the uterus is above the level of the umbilicus, depending on the preference and expertise of the surgeon. CONCLUSION: Through a structured, evidence-informed approach, an interdisciplinary panel provides a strong recommendation to perform appendectomy for complicated appendicitis or appendicolith, and laparoscopic or open appendectomy beyond the 20th week, based on the surgeon's preference and expertise.

Magnetically actuated endoscopes are currently transitioning in to clinical use for procedures such as colonoscopy, presenting numerous benefits over their conventional counterparts. Intelligent and easy-to-use control strategies are an essential part of their clinical effectiveness due to the un-intuitive nature of magnetic field interaction. However, work on developing intelligent control for these devices has mainly been focused on general purpose endoscope navigation. In this work, we investigate the use of autonomous robotic control for magnetic colonoscope intervention via biopsy, another major component of clinical viability. We have developed control strategies with varying levels of robotic autonomy, including semi-autonomous routines for identifying and performing targeted biopsy, as well as random quadrant biopsy. We present and compare the performance of these approaches to magnetic endoscope biopsy against the use of a standard flexible endoscope on bench-top using a colonoscopy training simulator and silicone colon model. The semi-autonomous routines for targeted and random quadrant biopsy were shown to reduce user workload with comparable times to using a standard flexible endoscope.
