Abstract
BACKGROUND The large amount of heterogeneous data collected in surgical/endoscopic practice calls for data-driven approaches as machine learning (ML) models. The aim of this study was to develop ML models to predict endoscopic sleeve gastroplasty (ESG) efficacy at 12 months defined by total weight loss (TWL) % and excess weight loss (EWL) % achievement. Multicentre data were used to enhance generalizability: evaluate consistency among different center of ESG practice and assess reproducibility of the models and possible clinical application. Models were designed to be dynamic and integrate follow-up clinical data into more accurate predictions, possibly assisting management and decision-making. METHODS ML models were developed using data of 404 ESG procedures performed at 12 centers across Europe. Collected data included clinical and demographic variables at the time of ESG and at follow-up. Multicentre/external and single center/internal and temporal validation were performed. Training and evaluation of the models were performed on Python's scikit-learn library. Performance of models was quantified as receiver operator curve (ROC-AUC), sensitivity, specificity, and calibration plots. RESULTS Multicenter external validation: ML models using preoperative data show poor performance. Best performances were reached by linear regression (LR) and support vector machine models for TWL% and EWL%, respectively, (ROC-AUC: TWL% 0.87, EWL% 0.86) with the addition of 6-month follow-up data. Single-center internal validation: Preoperative data only ML models show suboptimal performance. Early, i.e., 3-month follow-up data addition lead to ROC-AUC of 0.79 (random forest classifiers model) and 0.81 (LR models) for TWL% and EWL% achievement prediction, respectively. Single-center temporal validation shows similar results. CONCLUSIONS Although preoperative data only may not be sufficient for accurate postoperative predictions, the ability of ML models to adapt and evolve with the patients changes could assist in providing an effective and personalized postoperative care. ML models predictive capacity improvement with follow-up data is encouraging and may become a valuable support in patient management and decision-making.

Abstract
AIM Treatment pathways for significant rectal polyps differ depending on the underlying pathology, but pre-excision profiling is imperfect. It has been demonstrated that differences in fluorescence perfusion signals following injection of indocyanine green (ICG) can be analysed mathematically and, with the assistance of artificial intelligence (AI), used to classify tumours endoscopically as benign or malignant. This study aims to validate this method of characterization across multiple clinical sites regarding its generalizability, usability and accuracy while developing clinical-grade software to enable it to become a useful method. METHODS The CLASSICA study is a prospective, unblinded multicentre European observational study aimed to validate the use of AI analysis of ICG fluorescence for intra-operative tissue characterization. Six hundred patients undergoing transanal endoscopic evaluation of significant rectal polyps and tumours will be enrolled in at least five clinical sites across the European Union over a 4-year period. Video recordings will be analysed regarding dynamic fluorescence patterns centrally as software is developed to enable analysis with automatic classification to happen locally. AI-based classification and subsequently guided intervention will be compared with the current standard of care including biopsies, final specimen pathology and patient outcomes. DISCUSSION CLASSICA will validate the use of AI in the analysis of ICG fluorescence for the purposes of classifying significant rectal polyps and tumours endoscopically. Follow-on studies will compare AI-guided targeted biopsy or, indeed, AI characterization alone with traditional biopsy and AI-guided local excision versus traditional excision with regard to marginal clearance and recurrence.

Abstract
This systematic review and meta-analysis aimed to determine the short- and medium-term weight loss outcomes and comorbidity resolution following endoscopic sleeve gastroplasty. Our search identified 35 relevant studies containing data from 7525 patients. Overall, pooled short-term (12 months) total weight loss (TWL) was 16.2% (95% CI 13.1-19.4%) in 23 studies (n = 5659). Pooled medium-term TWL was 15.4% (95% CI 13.7-17.2%) in 10 studies (n = 4040). Diabetes resolution was 55.4% (95% CI 46-64%), hypertension resolution was 62.8% (95% CI 43-82%), dyslipidaemia resolution was 56.3% (95% CI 49-63%), and obstructive sleep apnoea resolution was 51.7% (95% CI 16.2-87.3%) in four studies (n = 480). This pooled analysis demonstrates that ESG can induce durable weight loss and resolution of obesity-associated comorbidities in patients with moderate obesity.

Abstract
Near-infrared fluorescence (NIRF) image-guided surgery is a useful tool that can help reduce perioperative complications and improve tissue recognition. Indocyanine green (ICG) dye is the most frequently used in clinical studies. ICG NIRF imaging has been used for lymph node identification. However, there are still many challenges in lymph node identification by ICG. There is increasing evidence that methylene blue (MB), another clinically applicable fluorescent dye, can also be useful in the intraoperative fluorescence-guided identification of structures and tissues. We hypothesized that MB NIRF imaging could be used for lymph node identification. The aim of this study was to evaluate the feasibility of intraoperative lymph node fluorescence detection using intravenously (IV) administered MB and compare it to ICG via a camera that has two dedicated near-infrared (NIR) channels. Three pigs were used in this study. ICG (0.2 mg/kg) was administered via a peripheral venous catheter followed by immediate administration of MB (0.25 mg/kg). NIRF images were acquired as video recordings at different time points (every 10 min) over an hour using the QUEST SPECTRUM® 3 system (Quest Medical Imaging, Middenmeer, The Netherlands), which has two dedicated NIR channels for simultaneous intraoperative fluorescence guidance. The 800 nm channel was used to capture ICG fluorescence and the 700 nm channel was used for MB. The target (lymph nodes and small bowel) and the background (vessels-free field of the mesentery) were highlighted as the regions of interest (ROIs), and corresponding fluorescence intensities (FI) from these ROIs were measured. The target-to-background ratio (TBR) was then computed as the mean FI of the target minus the mean FI of the background divided by the mean FI of the background. In all included animals, a clear identification of lymph nodes was achieved at all time points. The mean TBR of ICG in lymph nodes and small bowel was 4.57 ± 1.00 and 4.37 ± 1.70, respectively for the overall experimental time. Regarding MB, the mean TBR in lymph nodes and small bowel was 4.60 ± 0.92 and 3.27 ± 0.62, respectively. The Mann-Whitney U test of the lymph node TBR/small bowel TBR showed that the TBR ratio of MB was statistically significantly higher than ICG. The fluorescence optical imaging technology used allows for double-wavelength assessment. This feasibility study proves that lymph nodes can be discriminated using two different fluorophores (MB and ICG) with different wavelengths. The results suggest that MB has a promising potential to be used to detect lymphatic tissue during image-guided surgery. Further preclinical trials are needed before clinical translation.

Abstract
BACKGROUND Single snapshot imaging of optical properties (SSOP) is a relatively new non-invasive, real-time, contrast-free optical imaging technology, which allows for the real-time quantitative assessment of physiological properties, including tissue oxygenation (StO2). This study evaluates the accuracy of multispectral SSOP in quantifying bowel ischaemia in a preclinical experimental model. METHODS In six pigs, an ischaemic bowel segment was created by dividing the arcade branches. Five regions of interest (ROIs) were identified on the bowel loop, as follows: ROI 1: central ischaemic; ROI 2: left marginal; ROI 3: left vascularised; ROI 4: right marginal; and ROI 5: right vascularised. The Trident imaging system, specifically developed for real-time tissue oxygenation imaging using SSOP, was used to image before (T0) and after ischaemia induction. Capillary and systemic lactates were measured at each time point (T0, T15, T30, T45, T60), as well as StO2 values acquired by means of SSOP (SSOP-StO2). RESULTS The mean value of SSOP-StO2 in ROI 1 was 30.08 ± 6.963 and was significantly lower when compared to marginal ROIs (ROI 2 + ROI 4: 45.67 ± 10.02 p = < 0.0001), and to vascularised ROIs (ROI 3 + ROI 5: 48.08 ± 7.083 p = < 0.0001). SSOP-StO2 was significantly correlated with normalised lactates r = - 0.5892 p < 0.0001 and with histology r =- 0.6251 p = 0.0002. CONCLUSION Multispectral SSOP allows for a contrast-free accurate assessment of small bowel perfusion identifying physiological tissue oxygenation as confirmed with perfusion biomarkers.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is one of the most common diseases in North America and globally. The aim of this guideline is to provide evidence-based recommendations regarding the most utilized and available endoscopic and surgical treatments for GERD. METHODS Systematic literature reviews were conducted for 4 key questions regarding the surgical and endoscopic treatments for GERD in adults: preoperative evaluation, endoscopic vs surgical or medical treatment, complete vs partial fundoplication, and treatment for obesity (body mass index [BMI] ≥ 35 kg/m2) and concomitant GERD. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. Recommendations for future research were also proposed. RESULTS The consensus provided 13 recommendations. Through the development of these evidence-based recommendations, an algorithm was proposed for aid in the treatment of GERD. Patients with typical symptoms should undergo upper endoscopy, manometry, and pH-testing; additional testing may be required for patients with atypical or extra-esophageal symptoms. Patients with normal or abnormal findings on manometry should consider undergoing partial fundoplication. Magnetic sphincter augmentation or fundoplication are appropriate surgical procedures for adults with GERD. For patients who wish to avoid surgery, the Stretta procedure and transoral incisionless fundoplication (TIF 2.0) were found to have better outcomes than proton pump inhibitors alone. Patients with concomitant obesity were recommended to undergo either gastric bypass or fundoplication, although patients with severe comorbid disease or BMI > 50 should undergo Roux-en-Y gastric bypass for the additional benefits that follow weight loss. CONCLUSION Using the recommendations an algorithm was developed by this panel, so that physicians may better counsel their patients with GERD. There are certain patient factors that have been excluded from included studies/trials, and so these recommendations should not replace surgeon-patient decision making. Engaging in the identified research areas may improve future care for GERD patients.

Abstract
Ischemia-reperfusion injury during major hepatic resections is associated with high rates of post-operative complications and liver failure. Real-time intra-operative detection of liver dysfunction could provide great insight into clinical outcomes. In the present study, we demonstrate the intra-operative application of a novel optical technology, hyperspectral imaging (HSI), to predict short-term post-operative outcomes after major hepatectomy. We considered fifteen consecutive patients undergoing major hepatic resection for malignant liver lesions from January 2020 to June 2021. HSI measures included tissue water index (TWI), organ hemoglobin index (OHI), tissue oxygenation (StO2%), and near infrared (NIR). Pre-operative, intra-operative, and post-operative serum and clinical outcomes were collected. NIR values were higher in unhealthy liver tissue (p = 0.003). StO2% negatively correlated with post-operative serum ALT values (r = -0.602), while ΔStO2% positively correlated with ALP (r = 0.594). TWI significantly correlated with post-operative reintervention and OHI with post-operative sepsis and liver failure. In conclusion, the HSI imaging system is accurate and precise in translating from pre-clinical to human studies in this first clinical trial. HSI indices are related to serum and outcome metrics. Further experimental and clinical studies are necessary to determine clinical value of this technology.

Abstract
Complete mesocolic excision (CME), which involves the adequate resection of the tumor-bearing colonic segment with “en bloc” removal of its mesocolon along embryological fascial planes is associated with superior oncological outcomes. However, CME presents a higher complication rate compared to non-CME resections due to a higher risk of vascular injury. Hyperspectral imaging (HSI) is a contrast-free optical imaging technology, which facilitates the quantitative imaging of physiological tissue parameters and the visualization of anatomical structures. This study evaluates the accuracy of HSI combined with deep learning (DL) to differentiate the colon and its mesenteric tissue from retroperitoneal tissue. In an animal study including 20 pig models, intraoperative hyperspectral images of the sigmoid colon, sigmoid mesentery, and retroperitoneum were recorded. A convolutional neural network (CNN) was trained to distinguish the two tissue classes using HSI data, validated with a leave-one-out cross-validation process. The overall recognition sensitivity of the tissues to be preserved (retroperitoneum) and the tissues to be resected (colon and mesentery) was 79.0 ± 21.0% and 86.0 ± 16.0%, respectively. Automatic classification based on HSI and CNNs is a promising tool to automatically, non-invasively, and objectively differentiate the colon and its mesentery from retroperitoneal tissue.

Abstract
Over the last decade fluorescence-guided surgery has been primarily focused on the NIR-I window. However, the NIR-I window has constraints, such as limited penetration and scattering. Consequently, exploring the performance of NIR-I dyes at longer wavelengths (i.e., the NIR-II window) is crucial to expanding its application. Two fluorophores were used in three pigs to identify the mean fluorescence intensity (MFI) using two commercially available NIR-I and NIR-II cameras. The near-infrared coating of equipment (NICE) was used to identify endoluminal surgical catheters and indocyanine green (ICG) for common bile duct (CBD) characterization. The NIR-II window evaluation showed an MFI of 0.4 arbitrary units (a.u.) ± 0.106 a.u. in small bowel NICE-coated catheters and an MFI of 0.09 a.u. ± 0.039 a.u. in gastric ones. In CBD characterization, the ICG MFI was 0.12 a.u. ± 0.027 a.u., 0.18 a.u. ± 0.100 a.u., and 0.22 a.u. ± 0.041 a.u. at 5, 35, and 65 min, respectively. This in vivo imaging evaluation of NIR-I dyes confirms its application in the NIR-II domain. To the best of our knowledge, this is the first study assessing the MIF of NICE in the NIR-II window using a commercially available system. Further comparative trials are necessary to determine the superiority of NIR-II imaging systems.

Abstract
This study compares laparoscopic RYGB (L-RYGB) and robotic RYGB (R-RYGB) performed by the same team after the learning curve in both approaches. A retrospective cohort study was done, and the surgical outcome was analyzed in 30 days and 12 months for patients with similar characteristics and an equal number of cases in each group (233 cases). Four hundred and sixty-six patients were included in this study. Mean age was 46.8 ± 8.3 years and 2/3 were women. R-RYGB presented a longer operative time (150.7 versus 135.4 min; p < 0.001) with no differences in the length of hospital stay. The main 30-day complications were G-J stricture, leakage, and intraluminal bleeding. The reoperation rate was 1.6% by leakage (G-J anastomosis) and was higher in R-RYGB (2.1 versus 0.4; p = 0.108). The multivariate analysis identified that L-RYGB was the factor independently associated with a LOS longer than 2 days (odds ratio: 4.7, 95% CI: 2.6-8.2, p value < 0.001). At the FU time (12 months), no differences between the groups were found. The outcomes between the groups after the learning curve did not present differences in terms of 30 days and 12 months of FU when same preoperative characteristics and an equal number of cases in each group are considered. L-RYGB was the unique independent factor associated with long LOS.

Abstract
Simple Summary Anastomotic leak is the most dangerous complication occurring after esophagectomy and its relationship with inadequate visceral perfusion is widely recognized. Currently, the adequate perfusion of the gastric conduit is intraoperatively assessed by surgeons using subjective indicators (e.g., serosal color or pulsatile flow of vessels). During the last decades, several innovative optical techniques based on the interaction of light with tissue have been developed to monitor perfusion in esophagogastric surgery. However, these innovative approaches are characterized by a lack of video rate and reproducibility. They also provide operator-dependent results and lengthen the surgical workflow. Single Snapshot imaging of Optical Properties (SSOP) is an optical technique, which can overcome such limitations, providing quantitative information on the optical properties of biological tissues over a large field of view. It is the first study to demonstrate the accuracy of SSOP in the quantification of serosal StO2% in a porcine gastric conduit model. Abstract Anastomotic leakage (AL) is a serious complication occurring after esophagectomy. The current knowledge suggests that inadequate intraoperative perfusion in the anastomotic site contributes to an increase in the AL rate. Presently, clinical estimation undertaken by surgeons is not accurate and new technology is necessary to improve the intraoperative assessment of tissue oxygenation. In the present study, we demonstrate the application of a novel optical technology, namely Single Snapshot imaging of Optical Properties (SSOP), used to quantify StO2% in an open surgery experimental gastric conduit (GC) model. After the creation of a gastric conduit, local StO2% was measured with a preclinical SSOP system for 60 min in the antrum (ROI-A), corpus (ROI-C), and fundus (ROI-F). The removed region (ROI-R) acted as ischemic control. ROI-R had statistically significant lower StO2% when compared to all other ROIs at T15, T30, T45, and T60 (p < 0.0001). Local capillary lactates (LCLs) and StO2% correlation was statistically significant (R = −0.8439, 95% CI −0.9367 to −0.6407, p < 0.0001). Finally, SSOP could discriminate resected from perfused regions and ROI-A from ROI-F (the future anastomotic site). In conclusion, SSOP could well be a suitable technology to assess intraoperative perfusion of GC, providing consistent StO2% quantification and ROIs discrimination.

Abstract
Background: Acute appendicitis is one of the most common causes of acute abdominal pain worldwide. Although several studies have tried to investigate effects of delayed appendectomy, robust recommendations on this topic are still lacking. The aim of this retrospective study was to evaluate the correlation between delayed surgical treatment in acute appendicitis and postoperative complications. Materials and Methods: A 5-year retrospective study was conducted including all patients aged >15 years who underwent laparoscopic appendectomy. Groups were categorized according to the time of in-hospital delay (IHD) (time from hospital admission to surgical incision) as Group A: Early appendectomy (IHD <8 hours) and Group B: Delayed appendectomy (IHD ≥8 hours). Demographics and clinical characteristics, operative time, appendicitis grading score according to disease severity score, and clinical outcomes were considered for analyses. Results: A total of 290 patients were included for statistical analysis: 145 patients (50%) in Group A and 145 patients (50%) in Group B. Patients' baseline characteristics were similar between groups. There were no statistically significant differences between groups A and B in terms of operative time (72.60 minutes versus 72.47 minutes, P = .061), use of drain (53.8% versus 46.2%, P = .731), postoperative complications (47.4% versus 52.6%, P = .812), and length of hospital stay (2.39 [1-24] versus 2.79 [1-12], P = .645). There were no 30-day readmissions in both groups. Overall mortality was 0.3%. Conclusion: Our results suggest that an IHD of ≥8 hours does not significantly increase the risk of complicated appendicitis, the incidence of perioperative complications, postoperative length of stay, or mortality.

Abstract
Background: After the first laparoscopic Roux-en-Y gastric bypass (RYGB) in 1994 by Wittgrove, the introduction of robot-assisted procedures was the next step in the surgical race to reduce invasiveness. This breakthrough allowed us to perform bariatric surgery with less surgical trauma in obese patients with metabolic disorders, producing an exponential increase in procedures performed. Methods: This is a retrospective cohort study of a prospective database for patients who underwent RYGB during a 7-year period through two different approaches, laparoscopic and robotic. The robotic cases were performed by two generations of the da Vinci platform (S and Xi), and three groups were identified and compared (L-RYGB, RYGB-S, and RYGB-Xi). Results: A total of 495 patients underwent RYGB, of which 224 by laparoscopy (45.2%) and 271 by robotic approach (54.7%): 134 RYGB-S and 137 RYGB-Xi. The majority of the patients (71.1%) were females, with a mean age of 46.2 years and a mean body mass index of 44 kg/m2. The mean intraoperative time and intraoperative complication rate were higher in the robotic groups, especially in the RYGB-S group. Postoperative complications were higher in the same group, with a rate of 11.9%, where the main leakage occurred on the upper part of the gastric pouch and not in the hand-sewed robotic anastomosis (7.5%). General mortality was 0.6%. We found no significant differences at 1-year percentage of total weight loss (%TWL); at 2 years, the RYGB-Xi group had the lowest %TWL (25.24 ± 14.54, P ≤ .001). Conclusions: The present study reflects our experience during the robotic bariatric introduction and performance since 2011. Features of the da Vinci S platform along our learning curve may explain a higher complication rate. The patients who have been operated by the RYGB-Xi system had lower complications than the laparoscopic group. The robotic approach did not differ with laparoscopy in terms of weight loss and chronic complications after 24 months of follow-up.

Abstract
Introduction: For the past 20 years, robotic surgical systems have been used for the Roux-en-Y gastric bypass (RYGB). The da Vinci Surgical System (Intuitive Surgical, Inc.) has been one of the most used robotic platforms. This study aims to retrospectively compare the performance of two models of surgical robots. Materials and Methods: A retrospective comparative study was conducted from a prospective database including all patients who underwent robotic RYGB (RRYGB) from 2011 to 2020. Results: Of a total of 277 patients included, 134 were in the RRYGB using the da Vinci S™ (RRYGB-S™) group and 143 were in the RRYGB using the da Vinci Xi™ (RRYGB-Xi™) group. The mean operative time in the RRYGB-S and RRYGB-Xi groups was 154 ± 28 and 151 ± 32 minutes, respectively (P = .510). The was no statistically significant difference in terms of intraoperative complications between the groups with regard to positive blue test, bleeding, and failure of stapler line. The readmission rate was higher in the RRGB-S group (14.1%) than in the RRYGB-Xi group (3.4%) (P = .004), and it was mainly due to major complications (P = .003) including pouch and gastrojejunostomy anastomotic leaks (P = .001). The nonsurgical complications were statistically significantly higher in the RRYGB-S group (7.4%) than in the RRYGB-Xi group (2.1%) (P < .05), as well as the surgical complications were higher in the RRYGB-S group (7.5%) than in the RRYGB-Xi group (0%) (P < .001). The mean percentage of the total weight loss at 1 and 2 years of follow-up did not show any statistically significant difference (P = .547). Conclusions: The higher complication rate in the S surgical system might be correlated with the initial learning curve and stressed the need for proper robotic surgical training and accurate strategies when introducing emerging technologies into the surgical practice.

Abstract
BACKGROUND The critical view of safety (CVS) is poorly adopted in surgical practices although it is ubiquitously recommended to prevent major bile duct injuries during laparoscopic cholecystectomy (LC). This study aims to investigate whether performing a short intraoperative time out can improve CVS implementation. STUDY DESIGN In this before versus after study, surgeons performing LCs at an academic center were invited to use a 5-second long time out to verify CVS before dividing the cystic duct (5-second rule). The primary aim was to compare the rate of CVS achievement for LCs performed in the year before versus the year after implementation of the 5-second rule. The CVS achievement rate was computed after exclusion of bailout procedures using a mediated video-based assessment made by two independent reviewers. Clinical outcomes, LC workflows, and postoperative reports were also compared. RESULTS 343 of the 381 LCs performed between December 2017 and November 2019 (171 before and 172 after implementation of the 5-second rule) were analyzed. The 5-second rule was associated with a significantly increased rate of CVS achievement (15.9 vs. 44.1% before vs. after the 5-second rule, respectively; P<0.001). Significant differences were also observed with respect to the rate of bailout procedures (8.2 vs. 15.7%; P=0.04), the median [IQR] time to clip the cystic duct or artery (00:17:26 [00:11:48, 00:28:35] vs. 00:23:12 [00:14:29, 00:31:45] duration; P=0.007), and the rate of postoperative CVS reporting (1.3 vs. 28.8%; P<0.001). Postoperative morbidity was comparable (1.8 vs. 2.3%; P=0.68). CONCLUSION Performing a short intraoperative time out was associated with an improved CVS achievement rate. Systematic intraoperative cognitive aids should be studied to sustain the uptake of guidelines.

Abstract
Background: Image-guided liver surgery and interventions are growing as part of the current trend to translate liver procedures into minimally invasive approaches. Hands-on surgical training in such techniques is required. Consequently, a meaningful and realistic liver tumor model using multi-imaging modalities, such as ultrasound (US), computed tomography (CT), magnetic resonance (MR), cone beam-CT (CBCT), is mandatory. The first aim of this study is to develop a novel tumor-mimic model and assess it with multi-imaging modalities. The second aim is to evaluate the usefulness of the model during image-guided liver procedures. Materials and Methods: The tumor-mimic model is made of a composition of hydrogel, smashed muscle, and gadolinium contrast solution. Five ex vivo livers and three pigs were included in the study. Procedures were performed in an experimental hybrid operating room. Under general anesthesia, US guidance was required to inject the biotumor formula into the pig's liver. US, CT, CBCT, and MR acquisitions were then performed after the initial injection. In vivo models were then used to perform liver procedures, including US-guided biopsy, radiofrequency ablation, and laparoscopic resection. Results: The formula developed is easily injected generating a tissue-like material. Visualization using multi-imaging modalities was appropriate, thereby allowing to perform image-guided techniques. Conclusion: A novel design of an in vivo and ex vivo tissue-like tumor liver model is presented. Due to the multimodality imaging appraisal, it may provide a realistic and meaningful model allowing to perform image-guided liver procedures.

Abstract
BACKGROUND Endoscopic sleeve gastroplasty (ESG) is a promising bariatric endoluminal procedure. Restriction and shortening of the stomach are obtained by means of non-resorbable full-thickness sutures, thus inducing the formation of several endoluminal pouches in which food can stagnate. The effect of ESG on the upper gastrointestinal tract has never been investigated. OBJECTIVES This study objectively evaluates endoscopic macroscopic and histopathologic changes within 12-month follow-up (FU) in patients who underwent ESG. SETTING Retrospective study on a prospective database of patients who underwent ESG at our tertiary referral center between October 2016 and March 2019. METHODS All consecutive patients undergoing upper endoscopy (EGD) preoperatively and 6 and 12 months after ESG were included. The upper gastrointestinal tract was evaluated for mucosal abnormalities and biopsies were systematically taken. RESULTS Eighty-six patients were included. EGD results were as follows: esophagitis decreased from 14% preoperatively to 3.6% and 1.2% at 6- and 12-month FU, respectively (P = .001); 19.8% of patients presented preoperatively a type I hiatal hernia <4 cm and showed no size increment or de novo hiatal hernia at 6- and 12-months. The rate of preoperative hyperemic (23.2%) and erosive (3.5%) gastropathy decreased to 9.5% and 1.2% at 6 months and 17.4% and 1.2% at 12 months, respectively. Gastric ulcer (4.7%), duodenal hyperemic mucosa (1.2%) and duodenal micro-ulcerations (2.3%) detected preoperatively were not present at 6- and 12-month EGD. The rate of histopathological disease, which was 68.1% preoperatively, dropped to 29.2% at 12 months, chronic gastritis decreased from 40.3% to 26.4%, acute gastritis from 9.7% to 0%, and acute inflammation on chronic gastritis from 18% to 2.8% (P < .001). CONCLUSION ESG is a safe procedure that does not promote the new onset of macroscopic and histopathologic abnormalities within 1-year follow-up.

Abstract
Background. Laparoscopic Roux-en-Y gastric bypass (GBP) is an essential bariatric surgical procedure which is globally performed because of the associated effective weight loss and resolution of metabolic comorbidities, such as diabetes and dyslipidemia. Although some complications may occur, hypoglycemia is a rare complication, which can lead to lethal consequences. We aimed to describe the technical aspects and surgical results after reversal to normal anatomy (RNA). Methods. We conducted a retrospective data analysis including 16 patients who underwent laparoscopic RNA from 2011 to 2018. All data were archived in a prospective database. Previous bariatric surgery and postoperative outcomes were analyzed. Results. Sixteen patients underwent RNA, most of them after GBP, and 15 patients required sleeve gastrectomy. Among them, 80% were women; 5 patients presented with postoperative complications, such as colitis with intra-abdominal collection (n = 1), gastric leak (n = 2) treated with an endoprosthesis, mesenteric venous thrombosis (n = 1), and intra-abdominal bleeding (n = 1). Mean length of hospital stay was 5.93 (3-30). All patients recovered from their initial condition although 3 patients presented with mild hypoglycemia during follow-up. Seven patients regained weight (43.75%), and another 4 developed gastroesophageal reflux disease (25%). Conclusions. These laparoscopic RNA results are acceptable, indicating a clinical improvement in the hypoglycemic syndrome in all patients.

Abstract
OBJECTIVES To review the evidence regarding the outcomes of laparoscopic techniques in cases of splenomegaly. BACKGROUND Endoscopic approaches such as laparoscopic, hand-assisted laparoscopic, and robotic surgery are commonly used for splenectomy, but the advantages in cases of splenomegaly are controversial. REVIEW METHODS We conducted a systematic review using PRISMA guidelines. PubMed/MEDLINE, ScienceDirect, Scopus, Cochrane Library, and Web of Science were searched up to February 2020. RESULTS Nineteen studies were included for meta-analysis. In relation to laparoscopic splenectomy (LS) versus open splenectomy (OS), 12 studies revealed a significant reduction in length of hospital stay (LOS) of 3.3 days (p = <0.01) in the LS subgroup. Operative time was higher by 44.4 min (p < 0.01) in the LS group. Blood loss was higher in OS 146.2 cc (p = <0.01). No differences were found regarding morbimortality. The global conversion rate was 19.56%. Five studies compared LS and hand-assisted laparosocpic splenectomy (HALS), but no differences were observed in LOS, blood loss, or complications. HALS had a significantly reduced conversion rate (p < 0.01). In two studies that compared HALS and OS (n = 66), HALS showed a decrease in LOS of 4.5 days (p < 0.01) and increase of 44 min in operative time (p < 0.01), while OS had a significantly higher blood loss of 448 cc (p = 0.01). No differences were found in the complication rate. CONCLUSION LS is a safe approach for splenomegaly, with clear clinical benefits. HALS has a lower conversion rate. Higher-quality confirmatory trials with standardized splenomegaly grading are needed before definitive recommendations can be provided. Prospero registration number: CRD42019125251.

Abstract
The management of morbidly obese patients with a concomitant ventral hernia (VH) is a great challenge for surgeons. There is controversy over the optimal strategy to tackle both health problems, requiring an individualized approach. Obese patients have a higher recurrence rate after hernia repair, and bariatric surgery in the presence of a VH can be difficult. As morbid obesity is related with severe comorbidities, including increased cardiovascular and anesthetic risks, some advocate for a single-stage strategy. A primary hernia repair carried out during the bariatric surgery, however, may increase morbidity without definitively solving the problem. Biological meshes are expensive and also have a high recurrence rate. The laparoscopic placement of a synthetic mesh offers good results, but it is worrisome because bariatric surgery is a clean-contaminated procedure. Moreover, there is a great chance that a plastic surgery would be necessary after completing the weight-loss process, and the abdominal wall surgery could be performed at that point. There are many arguments, but the evidence is weak. We present an extensive review of the currently available literature on the management of VH in morbidly obese patients. We aim to provide objective information regarding the pros and cons of the different strategies that have been proposed, to facilitate the selection of the best approach to individual morbidly obese patients with abdominal wall hernias precising both of surgical repair.

Abstract
Introduction: Laparoscopic cholecystectomy (LC) is the gold standard performed by the majority of surgeons worldwide, and the use of single-port cholecystectomy remains a matter of debate. Single-port magnetic-assisted cholecystectomy (SPMAC) was described as an alternative because of its ability for proper triangulation and the advantage of reducing port surgery. The objective of this study is to describe the initial experience of SPMAC and evaluate the surgical learning curve. Materials and Methods: A prospective cohort was conducted between February 2017 and August 2018; 60 patients completed the inclusion criteria. Variables analyzed were gender, age, body mass index, American Society of Anesthesiologist (ASA) classification, operative time, hospital stay, intraoperative bleeding, and conversion rate. Postoperative pain was measured with a visual analogue scale (VAS). Aesthetic perception was measured by the cosmetic visual analogue scale (CVAS). The postoperative complications were graded according to Clavien-Dindo classification, and the cumulative sum (CUSUM) model was used for evaluating the learning curve. Results: The mean operatory time was 56.1 minutes. With regard to the postoperative pain variable, the VAS value was 2 out of 10 in 78.33% of patients. With regard to aesthetic satisfaction, CVAS was reported to be 10 out of 10 in 96.67% of patients. Conversion rate was 0%. The learning curve of operative time was reached at the 22nd patient, according to the CUSUM chart. Conclusions: SPMAC is feasible and effective; in our consideration, an acceptable learning curve considering benign gallbladder pathology is one of the most prevalent in general surgery. Further comparative studies with conventional LC and SPMAC need to be performed to conduct a proper comparison.

Abstract
Necrotizing fasciitis (NF) is a complicated soft tissue infection frequently associated with severe sepsis if an early medical and surgical treatment is not performed. We report two postoperative cases of severe NF after oophorectomy and colorectal resection. Because of the similarity with more benign skin infections at the early steps, clinical suspicion is crucial. Surgical exploration and resection will provide both the diagnosis confirming necrotizing infection of the fascia with vessels and treatment. Also, empirical broad-spectrum antibiotics must be initiated as soon as possible. Regardless of the presence of risk factors, NF is a condition with a high mortality rate and only an expeditious and undelayed treatment may improve the patient's outcome. Surgical focus control requires wide and repeated resections, and planned reconstructive plastic surgery might be necessary.

Abstract
INTRODUCTION The traumatic injuries to the tongue can go form section to partial or complete amputation, the latter being a rare presentation in the setting of facial trauma or even in patients with mental illness. CASE REPORT We present 25-year-old patient with traumatic partial amputation of the tongue who presented to the emergency department with successful surgical repair with good functional and esthetic outcome. DISCUSSION The tongue can suffer a broad type of traumatic injuries, in the setting of active bleeding, the muscular planes must be closed with absorbable sutures to stop the hemorrhage and prevent hematoma formation. Tongue surgical repair in the setting of a total section requires integrity of arterial and venous flow, so anastomosis must be executed. CONCLUSION Amputation of the tongue can put the patient's life at risk and its management needs to be mastered by the surgeons treating polytraumatized patients.

Abstract
Cation Exchange Resins have been the mainstream treatment for chronic hyperkalemia. In 1987 the first case series of uremic patients with colonic perforations associated with the use of sodium polystyrene sulfonate was reported. The pathologic damage of Cation Exchange Resin in gastrointestinal tract goes from mucosal edema, ulcers, pseudomembranes, and the most severe transmural necrosis. Surgeons must avoid therapies with intestinal osmotic challenge implication in patients presenting gastrointestinal adverse reactions derived from Cation Exchange Resins.
Introduction Since 1961 the use of Cation Exchange Resins has been the mainstream treatment for chronic hyperkalemia. For the past 25 years different kind of complications derived from its clinical use have been recognized, being the colonic necrosis the most feared and lethal of all. Presentation of case We report a case of a 72-year-old patient with chronic kidney disease, treated with calcium polystyrene sulfonate for hyperkalemia treatment who presented in the emergency department with constipation treated with hypertonic cathartics. With clinical deterioration 48 h later progressed with colonic necrosis requiring urgent laparotomy, sigmoidectomy and open abdomen management with subsequent rectal stump perforation and dead. The histopathology finding: calcium polystyrene sulfonate embedded in the mucosa, consistent with the cause of perforation. Discussion Lillemoe reported the first case series of five uremic patients with colonic perforation associated with the use of SPS in sorbitol in 1987 and in 2009 the FDA removed from the market the SPS containing 70% of sorbitol. The pathophysiologic change of CER goes from mucosal edema, ulcers, pseudomembranes, and the most severe case transmural necrosis. Up to present day, some authors have questioned the use of CER in the setting of lowering serum potassium. Despite its worldwide use in hyperkalemia settings, multiple studies have not demonstrated a significant potassium excretion by CER. Conclusion Despite the low incidence of colonic complication and lethal colonic necrosis associated with the CER clinical use, the general surgeon needs a high index of suspicion when dealing with patients treated with CER and abdominal pain.

Abstract
In 1986 Professor R J Heald published in The Lancet his new technique which he called Total Mesorectal Excision; today this is the gold standard for the surgical management of rectal cancer. In Total Mesorectal Excision (TME), the mesorectum is the term used to describe all the peri-rectal connective tissue including the posterior sheath of the endopelvic fascia containing the peri-rectal neurovascular structures. However, the mesenterium is a defined structure composed of a double layer of peritoneum which does not include the endopelvic fascia and the lateral rectal stalks, so these should not be included in the term 'mesorectum'. In our globalized medical culture it is important to use anatomic terms approved by the International Federation of Associations of Anatomists, as contained in the Terminologia Anatomica produced by the Federative International Programme for Anatomical Terminology (FIPAT). The term mesorectum is not listed in the Terminologia Anatomica.
