RESUMEN
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: Ideal visualization of fluorescent cholangiography during laparoscopic cholecystectomy is when maximum fluorescence into biliary ducts and absent signal into liver parenchyma, defined as "signal to background ratio" (SBR), is obtained. Such condition is mainly dependent by indocyanine green (ICG) dose and timing. The aim of this study was to identify the ideal ICG dose to obtain the best possible intraoperative visualization of the extra-hepatic biliary tree. METHODS: The first part of the study was used to define a range of small weight-based ICG dosages using the mathematical function bisection method. During the second part of the study, the midpoint dose of the identified range, was tested in 50 consecutive cholecystectomies using a laser-based fluorescence laparoscopic camera (SynergyID system by Arthrex, Naples, FL, USA). Timing administration was set at 1 h before surgery, since this is the most common situation in clinical practice. Fluorescence intensity of bile ducts and liver parenchyma were assessed both subjectively, by blinded operative surgeon, as well as objectively, using an image analysis software (Fiji plugin), before and after Calot's triangle dissection. RESULTS: Fourteen patients were included in the first part of the study and ICG dose between 0.01191406 and 0.0119873 mg/kg was identified. The second part confirmed previous results after testing the dosage equal to 0.0119 mg/kg (midpoint of the defined range) in 50 consecutive cholecystectomies. Cystic duct was identified in 66 and 100% of cases before and after dissection of Calot's triangle respectively. On the other hand, common bile duct was identified in 82 and 92% before and after dissection respectively. Subjective and objective SBRs confirmed the benefit of the identified ICG dose. CONCLUSION: ICG dose calculated by 0.0119 mg/kg administered one hour before surgery allows an ideal intraoperative visualization of the extra-hepatic biliary tree.

PURPOSE: Lymphadenectomy represents a fundamental step during gastrointestinal cancer resection, as the removal of an adequate number of lymph nodes is crucial to define the stage of the disease and prognosis. Lymphadenectomy during gastric and colorectal resection and adrenalectomy for cancer are technically demanding and can be associated with risk of bleeding. To date, lymphadenectomy is often performed without any visual aid. Indocyanine green fluorescence for lymph node mapping can provide better intraoperative visualization. The purpose of this review is to report the current evidence on this topic. MATERIALS AND METHODS: A systematic research of the electronic databases Medline, Embase and Google Scholar was conducted from the inception to December 2022. RESULTS: This review summarizes the current evidence of techniques and results of fluorescence guided lymphatic mapping during gastrointestinal and adrenal surgery. CONCLUSION: According to this review, ICG guided lymphadenectomy for gastrointestinal tumours and adrenocortical carcinoma is feasible and safe. In gastrointestinal tumours it allows higher number of harvested lymph nodes.

The application of new robotic platforms in colorectal surgery has increased greatly in the last 10 years. New systems have been released and entered the surgical panorama, broadening the technological offer. Robotic surgery applied to colorectal oncological surgery has been widely described. Hybrid robotic surgery in right sided colonic cancer has been previously reported. According to the site and local extension of a right-sided colon cancer, a different lymphadenectomy could be required. For more distant and locally advanced tumors a complete mesocolic excision (CME) is indicated. CME for right colon cancer is a complex operation compared to standard right hemicolectomy. Therefore a hybrid robotic system may be effectively applied to CME during a minimally-invasive right hemicolectomy to improve the dissection accuracy. Here we report a step-by-step hybrid laparoscopic/robotic right hemicolectomy with CME performed with the Versius Surgical System, a tele-operated surgical robotic system intended for the use of robotic assisted surgery.

BACKGROUND: In recent decades, the use of near-infrared light and fluorescence-guidance during open and laparoscopic surgery has exponentially expanded across various clinical settings. However, tremendous variability exists in how it is performed. OBJECTIVE: In this first published survey of international experts on fluorescence-guided surgery, we sought to identify areas of consensus and nonconsensus across 4 areas of practice: fundamentals; patient selection/preparation; technical aspects; and effectiveness and safety. METHODS: A Delphi survey was conducted among 19 international experts in fluorescence-guided surgery attending a 1-day consensus meeting in Frankfurt, Germany on September 8th, 2019. Using mobile phones, experts were asked to anonymously vote over 2 rounds of voting, with 70% and 80% set as a priori thresholds for consensus and vote robustness, respectively. RESULTS: Experts from 5 continents reached consensus on 41 of 44 statements, including strong consensus that near-infrared fluorescence-guided surgery is both effective and safe across a broad variety of clinical settings, including the localization of critical anatomical structures like vessels, detection of tumors and sentinel nodes, assessment of tissue perfusion and anastomotic leaks, delineation of segmented organs, and localization of parathyroid glands. Although the minimum and maximum safe effective dose of ICG were felt to be 1 to 2âmg and >10âmg, respectively, there was strong consensus that determining the optimum dose, concentration, route and timing of ICG administration should be an ongoing research focus. CONCLUSIONS: Although fluorescence imaging was almost unanimously perceived to be both effective and safe across a broad range of clinical settings, considerable further research remains necessary to optimize its use.

BACKGROUND: A computer vision (CV) platform named EndoDigest was recently developed to facilitate the use of surgical videos. Specifically, EndoDigest automatically provides short video clips to effectively document the critical view of safety (CVS) in laparoscopic cholecystectomy (LC). The aim of the present study is to validate EndoDigest on a multicentric dataset of LC videos. METHODS: LC videos from 4 centers were manually annotated with the time of the cystic duct division and an assessment of CVS criteria. Incomplete recordings, bailout procedures and procedures with an intraoperative cholangiogram were excluded. EndoDigest leveraged predictions of deep learning models for workflow analysis in a rule-based inference system designed to estimate the time of the cystic duct division. Performance was assessed by computing the error in estimating the manually annotated time of the cystic duct division. To provide concise video documentation of CVS, EndoDigest extracted video clips showing the 2 min preceding and the 30 s following the predicted cystic duct division. The relevance of the documentation was evaluated by assessing CVS in automatically extracted 2.5-min-long video clips. RESULTS: 144 of the 174 LC videos from 4 centers were analyzed. EndoDigest located the time of the cystic duct division with a mean error of 124.0 ± 270.6 s despite the use of fluorescent cholangiography in 27 procedures and great variations in surgical workflows across centers. The surgical evaluation found that 108 (75.0%) of the automatically extracted short video clips documented CVS effectively. CONCLUSIONS: EndoDigest was robust enough to reliably locate the time of the cystic duct division and efficiently video document CVS despite the highly variable workflows. Training specifically on data from each center could improve results; however, this multicentric validation shows the potential for clinical translation of this surgical data science tool to efficiently document surgical safety.

BACKGROUND: Choledocholithiasis presents in a considerable proportion of patients with gallbladder disease. There are several management options, including preoperative or intraoperative endoscopic cholangiopancreatography (ERCP), and laparoscopic common bile duct exploration (LCBDE). OBJECTIVE: To develop evidence-informed, interdisciplinary, European recommendations on the management of common bile duct stones in the context of intact gallbladder with a clinical decision to intervene to both the gallbladder and the common bile duct stones. METHODS: We updated a systematic review and network meta-analysis of LCBDE, preoperative, intraoperative, and postoperative ERCP. We formed evidence summaries using the GRADE and the CINeMA methodology, and a panel of general surgeons, gastroenterologists, and a patient representative contributed to the development of a GRADE evidence-to-decision framework to select among multiple interventions. RESULTS: The panel reached unanimous consensus on the first Delphi round. We suggest LCBDE over preoperative, intraoperative, or postoperative ERCP, when surgical experience and expertise are available; intraoperative ERCP over LCBDE, preoperative or postoperative ERCP, when this is logistically feasible in a given healthcare setting; and preoperative ERCP over LCBDE or postoperative ERCP, when intraoperative ERCP is not feasible and there is insufficient experience or expertise with LCBDE (weak recommendation). The evidence summaries and decision aids are available on the platform MAGICapp ( https://app.magicapp.org/#/guideline/nJ5zyL ). CONCLUSION: We developed a rapid guideline on the management of common bile duct stones in line with latest methodological standards. It can be used by healthcare professionals and other stakeholders to inform clinical and policy decisions. GUIDELINE REGISTRATION NUMBER: IPGRP-2022CN170.

INTRODUCTION: There has been an increasing interest for the laparoscopic treatment of early gastric cancer, especially among Eastern surgeons. However, the oncological effectiveness of Laparoscopic Gastrectomy (LG) for Advanced Gastric Cancer (AGC) remains a subject of debate, especially in Western countries where limited reports have been published. The aim of this paper is to retrospectively analyze short- and long-term results of LG for AGC in a real-life Western practice. MATERIALS AND METHODS: All consecutive cases of LG with D2 lymphadenectomy for AGC performed from January 2005 to December 2019 at seven different surgical departments were analyzed retrospectively. The primary outcome was diseases-free survival (DFS). Secondary outcomes were overall survival (OS), number of retrieved lymph nodes, postoperative morbidity and conversion rate. RESULTS: A total of 366 patients with stage II and III AGC underwent either total or subtotal LG. The mean number of harvested lymph nodes was 25 ± 14. The mean hospital stay was 13 ± 10 days and overall postoperative morbidity rate 27.32%, with severe complications (grade ≥ III) accounting for 9.29%. The median follow-up was 36 ± 16 months during which 90 deaths occurred, all due to disease progression. The DFS and OS probability was equal to 0.85 (95% CI 0.81-0.89) and 0.94 (95% CI 0.92-0.97) at 1 year, 0.62 (95% CI 0.55-0.69) and 0.63 (95% CI 0.56-0.71) at 5 years, respectively. CONCLUSION: Our study has led us to conclude that LG for AGC is feasible and safe in the general practice of Western institutions when performed by trained surgeons.

BACKGROUND: Evidence and practice recommendations on the use of transanal total mesorectal excision (TaTME) for rectal cancer are conflicting. OBJECTIVE: We aimed to summarize best evidence and develop a rapid guideline using transparent, trustworthy, and standardized methodology. METHODS: We developed a rapid guideline in accordance with GRADE, G-I-N, and AGREE II standards. The steering group consisted of general surgeons, members of the EAES Research Committee/Guidelines Subcommittee with expertise and experience in guideline development, advanced medical statistics and evidence synthesis, biostatisticians, and a guideline methodologist. The guideline panel consisted of four general surgeons practicing colorectal surgery, a radiologist with expertise in rectal cancer, a radiation oncologist, a pathologist, and a patient representative. We conducted a systematic review and the results of evidence synthesis by means of meta-analyses were summarized in evidence tables. Recommendations were authored and published through an online authoring and publication platform (MAGICapp), with the guideline panel making use of an evidence-to-decision framework and a Delphi process to arrive at consensus. RESULTS: This rapid guideline provides a weak recommendation for the use of TaTME over laparoscopic or robotic TME for low rectal cancer when expertise is available. Furthermore, it details evidence gaps to be addressed by future research and discusses policy considerations. The guideline, with recommendations, evidence summaries, and decision aids in user-friendly formats can also be accessed in MAGICapp: https://app.magicapp.org/#/guideline/4494 . CONCLUSIONS: This rapid guideline provides evidence-informed trustworthy recommendations on the use of TaTME for rectal cancer.

INTRODUCTION: The aim of this study was to develop a reliable objective structured assessment of technical skills (OSATS) score for linear-stapled, hand-sewn closure of enterotomy intestinal anastomoses (A-OSATS). MATERIALS AND METHODS: The Delphi methodology was used to create a traditional and weighted A-OSATS score highlighting the more important steps for patient outcomes according to an international expert consensus. Minimally invasive novices, intermediates, and experts were asked to perform a minimally invasive linear-stapled intestinal anastomosis with hand-sewn closure of the enterotomy in a live animal model either laparoscopically or robot-assisted. Video recordings were scored by two blinded raters assessing intrarater and interrater reliability and discriminative abilities between novices (n = 8), intermediates (n = 24), and experts (n = 8). RESULTS: The Delphi process included 18 international experts and was successfully completed after 4 rounds. A total of 4 relevant main steps as well as 15 substeps were identified and a definition of each substep was provided. A maximum of 75 points could be reached in the unweighted A-OSATS score and 170 points in the weighted A-OSATS score respectively. A total of 41 anastomoses were evaluated. Excellent intrarater (r = 0.807-0.988, p < 0.001) and interrater (intraclass correlation coefficient = 0.923-0.924, p < 0.001) reliability was demonstrated. Both versions of the A-OSATS correlated well with the general OSATS and discriminated between novices, intermediates, and experts defined by their OSATS global rating scale. CONCLUSION: With the weighted and unweighted A-OSATS score, we propose a new reliable standard to assess the creation of minimally invasive linear-stapled, hand-sewn anastomoses based on an international expert consensus. Validity evidence in live animal models is provided in this study. Future research should focus on assessing whether the weighted A-OSATS exceeds the predictive capabilities of patient outcomes of the unweighted A-OSATS and provide further validity evidence on using the score on different anastomotic techniques in humans.

INTRODUCTION: Despite progressive improvements in technical skills and instruments that have facilitated surgeons performing intracorporeal gastro-jejunal and jejuno-jejunal anastomoses, one of the big challenging tasks is handsewn knot tying. We analysed the better way to fashion a handsewn intracorporeal enterotomy closure after a stapled anastomosis. METHODS: All 579 consecutive patients from January 2009 to December 2019 who underwent minimally invasive partial gastrectomy for gastric cancer were retrospectively analysed. Different ways to fashion intracorporeal anastomoses were investigated: robotic versus laparoscopic approach; laparoscopic high definition versus three-dimensional versus 4K technology; single-layer versus double-layer enterotomies. Double-layer enterotomies were analysed layer by layer, comparing running versus interrupted suture; the presence versus absence of deep corner suture; and type of suture thread. RESULTS: Significantly lower rates of bleeding (p = 0.011) and leakage (p = 0.048) from gastro-jejunal anastomosis were recorded in the double-layer group. Barbed suture thread was significantly associated with reduced intraluminal bleeding and leakage rates both in the first (p = 0.042 and p = 0.010) and second layer (p = 0.002 and p = 0.029). CONCLUSIONS: Double-layer sutures using barbed suture thread both in first and second layer to fashion enterotomy closure result in lower intraluminal bleeding and anastomotic leak rates.

Background. The COVID-19 pandemic leads to several debates regarding the possible risk for healthcare professionals during surgery. SAGES and EAES raised the issue of the transmission of infection through the surgical smoke during laparoscopy. They recommended the use of smoke evacuation devices (SEDs) with CO2 filtering systems. The aim of the present study is to compare the efficacy of different SEDs evaluating the CO2 environmental dispersion in the operating theater. Methods. We prospectively evaluated the data of 4 group of patients on which we used different SEDs or standard trocars: AIRSEAL system (S1 group), a homemade device (S2 group), an AIRSEAL system + homemade device (S3 group), and with standard trocars and without SED (S4 group). Quantitative analysis of CO2 environmental dispersion was carried out associated to the following data in order to evaluate the pneumoperitoneum variations: a preset insufflation pressure, real intraoperative pneumoperitoneum pressure, operative time, total volume of insufflated CO2, and flow rate index. Results. 16 patients were prospectively enrolled. The [CO2] mean value was 711 ppm, 641 ppm, 593 ppm, and 761 ppm in S1, S2, S3, and S4 groups, respectively. The comparison between data of all groups showed statistically significant differences in the measured ambient CO2 concentration. Conclusion. All tested SEDs seem to be useful to reduce the CO2 environmental dispersion respect to the use of standard trocars. The association of AIRSEAL system and a homemade device seems to be the best solution combining an adequate smoke evacuation and a stable pneumoperitoneum during laparoscopic surgery.

BACKGROUND: This study aims (I) to evaluate whether the Multidimensional Prognostic Index (MPI) score is associated with postoperative outcomes and (II) to develop a prognostic model for individual complication-risk prediction following colorectal cancer (CRC) surgery. METHOD: This is a prospective multicentric cohort study. Consecutive ≥75-year-old candidates for elective CRC surgery were enrolled from October 2017 to August 2019. Patients underwent standardized preoperative geriatric assessment including the MPI. Patients with MPI score > 0.33 were classified as frail. Logistic regression models were employed to evaluate variables associated with major postoperative complications and mortality, using 10-fold cross-validated LASSO (least absolute shrinkage and selection operator) for model selection. RESULTS: In all, 104 patients were included, 34 (33%) had MPI score > 0.33. Major postoperative complications occurred in 52% of frail versus 16% of fit (MPI score ≤ 0.33) patients (p < .01). Both 30-day (9% vs. 0%; p = .033) and 90-day mortality (18% vs. 1%; p < .01) were higher among frail patients. In multivariate analysis, MPI score was associated with adverse outcomes. A final postoperative complication predictive model was created, including MPI score, gait-speed test, ASA (American Society of Anesthesiology) score, surgical approach, and stoma creation. CONCLUSION: MPI score is strongly associated with postoperative major complications in CRC elderly patients and it is a primary component of an individual prediction model.

BACKGROUND AND OBJECTIVES: In the setting of a minimally invasive approach, we aimed to compare short and long-term postoperative outcomes of patients treated with neoadjuvant therapy (NAT) + surgery or upfront surgery in Western population. METHODS: All consecutive patients from six Italian and one Serbian center with locally advanced gastric cancer who had undergone laparoscopic gastrectomy with D2 lymph node dissection were selected between 2005 and 2019. After propensity score-matching, postoperative morbidity and oncologic outcomes were investigated. RESULTS: After matching, 97 patients were allocated in each cohort with a mean age of 69.4 and 70.5 years. The two groups showed no difference in operative details except for a higher conversion rate in the NAT group (p = 0.038). The overall postoperative complications rate significantly differed between NAT + surgery (38.1%) and US (21.6%) group (p = 0.019). NAT was found to be related to a higher risk of postoperative morbidity in patients older than 60 years old (p = 0.013) but not in patients younger (p = 0.620). Conversely, no difference in overall survival (p = 0.41) and disease-free-survival (p = 0.34) was found between groups. CONCLUSIONS: NAT appears to be related to a higher postoperative complication rate and equivalent oncological outcomes when compared with surgery alone. However, poor short-term outcomes are more evident in patients over 60 years old receiving NAT.

INTRODUCTION: There has been a constant increase in the number of published surgical videos with preference for open-access sources, but the proportion of videos undergoing peer-review prior to publication has markedly decreased, raising questions over quality of the educational content presented. The aim of this study was the development and validation of a standard framework for the appraisal of surgical videos submitted for presentation and publication, the LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) video assessment tool. METHODS: An international committee identified items for inclusion in the LAP-VEGaS video assessment tool and finalised the marking score utilising Delphi methodology. The tool was finally validated by anonymous evaluation of selected videos by a group of validators not involved in the tool development. RESULTS: 9 items were included in the LAP-VEGaS video assessment tool, with every item scoring from 0 (item not presented in the video) to 2 (item extensively presented in the video), with a total marking score ranging from 0 to 18. The LAP-VEGaS video assessment tool resulted highly accurate in identifying and selecting videos for acceptance for conference presentation and publication, with high level of internal consistency and generalisability. CONCLUSIONS: We propose that peer review in adherence to the LAP-VEGaS video assessment tool could enhance the overall quality of published video outputs.

BACKGROUND: Anastomotic leakage (AL) is one of the dreaded complications following surgery in the digestive tract. Near-infrared fluorescence (NIRF) imaging is a means to intraoperatively visualize anastomotic perfusion, facilitating fluorescence image-guided surgery (FIGS) with the purpose to reduce the incidence of AL. The aim of this study was to analyze the current practices and results of NIRF imaging of the anastomosis in digestive tract surgery through the EURO-FIGS registry. METHODS: Analysis of data prospectively collected by the registry members provided patient and procedural data along with the ICG dose, timing, and consequences of NIRF imaging. Among the included upper-GI, colorectal, and bariatric surgeries, subgroup analysis was performed to identify risk factors associated with complications. RESULTS: A total of 1240 patients were included in the study. The included patients, 74.8% of whom were operated on for cancer, originated from 8 European countries and 30 hospitals. A total of 54 surgeons performed the procedures. In 83.8% of cases, a pre-anastomotic ICG dose was administered, and in 60.1% of cases, a post-anastomotic ICG dose was administered. A significant difference (p < 0.001) was found in the ICG dose given in the four pathology groups registered (range: 0.013-0.89 mg/kg) and a significant (p < 0.001) negative correlation was found between the ICG dose and BMI. In 27.3% of the procedures, the choice of the anastomotic level was guided by means of NIRF imaging which means that in these cases NIRF imaging changed the level of anastomosis which was first decided based on visual findings in conventional white light imaging. In 98.7% of the procedures, the use of ICG partly or strongly provided a sense of confidence about the anastomosis. A total of 133 complications occurred, without any statistical significance in the incidence of complications in the anastomoses, whether they were ICG-guided or not. CONCLUSION: The EURO-FIGS registry provides an insight into the current clinical practice across Europe with respect to NIRF imaging of anastomotic perfusion during digestive tract surgery.

AIM: To clarify the advantages of negative pressure therapy (NPT) compared to other methods of temporary abdominal closure (TAC) in the management of secondary peritonitis. METHODS: We retraced the history of known methods of TAC, and analyzed their advantages and disadvantages. We evaluated as the NPT mechanisms, both from the macroscopic that bio-molecular point of view, well suits to manage this difficult condition. RESULTS: The ideal TAC technique should be quick to apply, easy to change, protect and contain the abdominal viscera, decrease bowel edema, prevent loss of domain and abdominal compartment syndrome, limit contamination, allow egress of peritoneal fluid (and its estimation) and not result in adhesions. It should also be cost-effective, minimize the number of dressing changes and the number of surgical revisions, and ensure a high rate of early closure with a low rate of complications (especially entero-atmospheric fistula). For NPT, the reported fistula rate is 7%, primary fascial closure ranges from 33 to 100% (average 60%) and the mortality rate is about 20%. With the use of NPT as TAC, it may be possible to extend the window of time to achieve primary fascial closure (for up to 20-40 days). CONCLUSION: NPT has several potential advantages in open-abdomen (OA) management of secondary peritonitis and may make it possible to achieve all the goals suggested above for an ideal TAC system. Only trained staff should use NPT, following the manufacturer's instructions when commercial products are used. Even if there was a significant evolution in OA management, we believe that further research into the role of NPT for secondary peritonitis is necessary.

RESUMEN
BACKGROUND: Compromised tissue perfusion is a significant risk factor for anastomotic leakage after intestinal resection, leading to prolonged hospitalization, risk of recurrence after oncologic resection, and reduced survival. Thus, a tool reducing the risk of leakage is highly warranted. Quantitative indocyanine green angiography (Q-ICG) is a new method that provides surgeons with an objective evaluation of tissue perfusion. In this systematic review, we aimed to determine the optimal methodology for performing Q-ICG. METHOD: A comprehensive search of the literature was performed following the PRISMA guidelines. The following databases were searched: PubMed, Embase, Scopus, and Cochrane. We included all clinical studies that performed Q-ICG to assess visceral perfusion during gastrointestinal surgery. Bias assessment was performed with the Newcastle Ottawa Scale. RESULTS: A total of 1216 studies were screened, and finally, 13 studies were included. The studies found that intensity parameters (maximum intensity and relative maximum intensity) could not identify patients with anastomotic leakage. In contrast, the inflow parameters (time-to-peak, slope, and t1/2max) were significantly associated with anastomotic leakage. Only two studies performed intraoperative Q-ICG while the rest performed Q-ICG retrospectively based on video recordings. Studies were heterogeneous in design, Q-ICG parameters, and patient populations. No randomized studies were found, and the level of evidence was generally found to be low to moderate. CONCLUSION: The results, while heterogenous, all seem to point in the same direction. Fluorescence intensity parameters are unstable and do not reflect clinical endpoints. Instead, inflow parameters are resilient in a clinical setting and superior at reflecting clinical endpoints.

BACKGROUND: Surgical smoke is a well-recognized hazard in the operating room. At the beginning of the COVID-19 pandemic, surgical societies quickly published guidelines recommending avoiding laparoscopy or to consider open surgery because of the fear of transmission of SARS-CoV-2 through surgical smoke or aerosol. This narrative review of the literature aimed to determine whether there are any differences in the creation of surgical smoke/aerosol between laparoscopy and laparotomy and if laparoscopy may be safer than laparotomy. METHODS: A literature search was performed using the Pubmed, Embase and Google scholar search engines, as well as manual search of the major journals with specific COVID-19 sections for ahead-of-print publications. RESULTS: Of 1098 identified articles, we critically appraised 50. Surgical smoke created by electrosurgical and ultrasonic devices has the same composition both in laparoscopy and laparotomy. SARS-CoV-2 has never been found in surgical smoke and there is currently no data to support its virulence if ever it could be transmitted through surgical smoke/aerosol. CONCLUSION: If laparoscopy is performed in a closed cavity enabling containment of surgical smoke/aerosol, and proper evacuation of smoke with simple measures is respected, and as long as laparoscopy is not contraindicated, we believe that this surgical approach may be safer for the operating team while the patient has the benefits of minimally invasive surgery. Evidence-based research in this field is needed for definitive determination of safety.
