A global survey on the use of the international classification of diseases codes for metabolic dysfunction-associated fatty liver disease.

BACKGROUND: With the implementation of the 11th edition of the International Classification of Diseases (ICD-11) and the publication of the metabolic dysfunction-associated fatty liver disease (MAFLD) nomenclature in 2020, it is important to establish consensus for the coding of MAFLD in ICD-11. This will inform subsequent revisions of ICD-11. METHODS: Using the Qualtrics XM and WJX platforms, questionnaires were sent online to MAFLD-ICD-11 coding collaborators, authors of papers, and relevant association members. RESULTS: A total of 890 international experts in various fields from 61 countries responded to the survey. We also achieved full coverage of provincial-level administrative regions in China. 77.1% of respondents agreed that MAFLD should be represented in ICD-11 by updating NAFLD, with no significant regional differences (77.3% in Asia and 76.6% in non-Asia, p = 0.819). Over 80% of respondents agreed or somewhat agreed with the need to assign specific codes for progressive stages of MAFLD (i.e. steatohepatitis) (92.2%), MAFLD combined with comorbidities (84.1%), or MAFLD subtypes (i.e., lean, overweight/obese, and diabetic) (86.1%). CONCLUSIONS: This global survey by a collaborative panel of clinical, coding, health management and policy experts, indicates agreement that MAFLD should be coded in ICD-11. The data serves as a foundation for corresponding adjustments in the ICD-11 revision.

Roux-en-Y Gastric Bypass after Laparoscopic Sleeve Gastrectomy Failure: Could the Number of Previous Operations Influence the Outcome?

After a failed laparoscopic adjustable gastric band (LAGB), laparoscopic sleeve gastrectomy (LSG) has been proposed as revisional surgery. Those patients that receive a second restrictive procedure fall into a small subgroup of patients with more than one restrictive procedure (MRP). If also the second restrictive procedure fails, the correct surgical strategy is a challenge for the surgeon. Roux-en-Y gastric bypass (RYGB) may be an option but there is no evidence in the literature on whether the procedure is effective in treating failures after MRP. This study aims to evaluate the influence of the previous number of restrictive interventions (MRP vs single LSG) in the results of RYGB as revisional surgery. We have retrospectively analyzed patients who underwent conversion from laparoscopic sleeve gastrectomy (LSG), or from multiple restrictive procedures (MRP), to RYGB for weight regain (WR) or insufficient weight loss (IWL) between 2009 and 2019. The number of patients analyzed was 69 with conversion to RYGB after LSG and 44 after MRP. The reduction of excess weight (%TWL) at 3, 6, 12, 24 RYGB postoperative months was respectively of 11.03%, 16.39%, 21.43%, and 24.22% in the MRP group, and of 10.97%, 16.4%, 21.22%, and 22.71% in the LSG group. No significant difference was found in %TWL terms after RYGB for the MRP group and the LSG group with an overall %TWL, which was 11.00 ± 6.03, 16.40 ± 8.08, 21.30 ± 9.43, and 23.30 ± 9.91 respectively at 3, 6, 12, and 24 months. The linear regression model highlighted a positive relationship between the %EWL post-bypass at 24 months and the time elapsed only between the LSG and RYGB in the MRP group patients (p < 0.001). RYGB has proved to be a reliable technique with good results in terms of weight loss after failed bariatric surgery both in patients who previously underwent MRP and in those who underwent exclusively LSG. RYGB showed better results in patients who experienced WR than in those who had IWL from previous techniques.

Efficacy of Nissen Sleeve Gastrectomy on Mid-term Barrett's Esophagus Regression.

INTRODUCTION: Sleeve gastrectomy is the most commonly performed bariatric operation globally. The main complication is GERD. In the medium term, it can increase the incidence of Barrett's esophagus (BE), which is a risk factor for esophageal adenocarcinoma. Following conventional sleeve gastrectomy, BE is noted in up to 16% of patients postoperatively. Recently, Nissen sleeve gastrectomy (NSG) has been shown to reduce the frequency of postoperative GERD compared to conventional sleeve gastrectomy. This study aims to evaluate the impact of NSG on the incidence and remission of BE in the long term. MATERIAL AND METHOD: This bicentric retrospective study included 692 patients who received NSG from September 2013 to July 2021. All patients underwent preoperative upper GI endoscopy and were then scheduled to receive upper GI endoscopy between 1 and 2 years and then between 3 and 5 years postoperatively. BE was systematically confirmed by biopsies. RESULTS: Seventy-four patients had endoscopic suspicion of BE, which was confirmed on 54/692 patients by histology. The BE lesions consisted of 18.5% intestinal metaplasia and 75.9% fundal metaplasia. Among these 54 patients, 38 underwent endoscopic investigation within 2 years postoperatively. The biopsies showed healed BE in 25/38 patients (64.1%). At 5 years, two patients had proven BE. Concerning the incidence of BE post NSG: 234 performed the follow-up endoscopy within 2 years. The incidence of de novo BE is nil. CONCLUSION: The NSG is associated with healing of known BE in approximately two-thirds of patients at 2-year follow-up. This is consistent with the GERD improvement that has been shown with NSG.

Prospective evaluation of transoral outlet reduction (TORe) after Roux-en-Y gastric bypass (RYGB) failure.

BACKGROUND AND AIMS: Weight regain after RYGB is multifactorial including dilatation of the gastro-jejunal anastomosis. Transoral outlet reduction (TORe) procedure is a minimally invasive alternative to surgical anastomotic revision. METHODS: We conducted a prospective, multicenter, simple blind, randomized study in patients with weight regain following RYGB, comparing the efficacy of conventional nutritional and behavioral management associated with a TORe procedure (TORe group) with conventional management alone and a Sham procedure (Sham group). The main objective of this study was to evaluate the percentage of excess weight loss (%EWL) at 12 months after endoscopy. RESULTS: From January 2015 to January 2019, 73 subjects were randomized in four French Bariatric centers. The final analysis involved 50 subjects, 25 in each group, 44 women, 6 men, with an average BMI of 40.6 kg/m2. At 12 months, the average %EWL was significantly higher in the TORe group than in the Sham group (13.5 ± 14.1 vs. - 0.77 ± 17.1; p = 0.002). Cohen's d was 0.91, indicating a large effect size of the procedure on the %EWL. There was no significant difference between groups concerning the improvement of obesity-related comorbidities (diabetes and dyslipidemia) and quality of life at 12 months. We report frequent adverse events in the TORe group (20% had adverse events related to the procedure). Three adverse events were serious, including two perforations of the gastro-jejunal anastomosis after TORe group that led to the premature termination of the study. CONCLUSIONS: After RYGBP failure linked to the dilatation of the gastro-jejunal anastomosis, TORe procedure with nutritional management results in significantly higher %EWL at 12 months compared to patients with nutritional management alone. As surgery, this minimally invasive endoscopic procedure can be associated with severe adverse events.

Conversion of one-anastomosis gastric bypass (OAGB) to Roux-en-Y gastric bypass (RYGB) for gastroesophageal reflux disease (GERD): who is more at risk? A multicenter study.

BACKGROUND: Although gastroesophageal reflux disease (GERD) affects 0.6% to 10% of patients operated on for one-anastomosis gastric bypass (OAGB), only about 1% require surgery to convert to Roux-en-Y gastric bypass (RYGB) [3-5]. The aim of the present study was to analyze the characteristics of OAGB patients converted to RYGB for GERD not responding to medical treatment. METHODS: This retrospective multicenter study included patients who underwent conversion from OAGB to RYGB for severe GERD. The conversion was performed with resection of the previous gastro-jejunal anastomosis and the use of the afferent loop as a new biliary loop. RESULTS: A total of 126 patients were included in the study. Of these patients, 66 (52.6%) had a past medical history of bariatric restrictive surgery (gastric banding, sleeve gastrectomy). A hiatal hernia (HH) was present in 56 patients (44.7%). The association between previous restrictive surgery and HH was recorded in 33 (26.2%) patients. Three-dimensional gastric computed tomography showed an average gastric pouch volume of 242.4 ± 55.1 cm3. Conversion to RYGB was performed on average 60 ± 35.6 months after OAGB. Seven patients (5.5%) experienced an early postoperative complication (4 patients grade IIIb and 3 grade IIb), and 3 (2.4%) a late complication. Patients showed further weight loss after RYGB conversion and an average of 24.8 ± 21.7 months after surgery, with a mean % of total weight loss (%TWL) of 6.9 ± 13.6 kg. From a clinical point of view, the problem of GERD was definitively solved in more than 90% of patients. CONCLUSIONS: Situations that weaken the esogastric junction appear to be highly frequent in patients operated on for OAGB and converted to RYGB for severe reflux. Similarly, the correct creation of the gastric pouch could play an important role in reducing the risk of conversion to RYGB for GERD.

Endoscopic Revisional Gastroplasty After Bariatric Surgery with a Single-Channel Endoscope.

BACKGROUND: Less invasive endoscopic bariatric procedures are under development for the management of recurrence of obesity. The purpose of the current manuscript was to evaluate the safety of the endoscopic revisional gastroplasty (ERG) for patients with recurrence of weight gain following different bariatric procedures. MATERIALS AND METHODS: This is a retrospective single-center study over 22 patients using the ERG between January 2020 to July 2022 at Bouchard Private Hospital (Marseille, France). The demographic data, past surgical history, obesity complications, time interval between the surgical and endoscopic procedures, and intra and postoperative parameters and outcomes were analyzed. RESULTS: A total of 22 patients underwent ERG: 19 female (86.4%) with a mean age of 34.2 years and a mean BMI of 32.9 kg/m2 (± 3.4). Average time between the revisional bariatric surgery and ERG was 14.4 months (range 5-36). There were 14 cases of LSG (77.8%), 9 cases of RYGBP (19.4%), and 3 cases with previous gastric band. All procedures were completed by endoscopy with no complication and a mean length of hospital stay of 1.1 days (± 0.9). The weight loss results at 1-year follow-up were available for 17 of the 22 patients: two patients were lost to follow-up (4%) and 3 patients had less than a 1-year follow-up from the ERG. The mean BMI, 1 year after ERG, was 28.7 kg/m2 (± 7.4); the mean BMI loss and %EWL were, respectively, 4.2 kg/m2 (± 4.7) and 53.1% (± 17). CONCLUSION: Endoscopic revisional gastroplasty represents a safe minimal invasive approach that can be considered an effective and well-tolerated procedure for patients with previous bariatric surgery.

Effect of Nutritional Deprivation after Sleeve Gastrectomy on Bone Mass, Periostin, Sclerostin and Semaphorin 4D: A Two-Year Longitudinal Study.

Bariatric surgery induces bone loss, but the exact mechanisms by which this process occurs are not fully known. The aims of this 2-year longitudinal study were to (i) investigate the changes in areal bone mineral density (aBMD) and bone turnover markers following sleeve gastrectomy (SG) and (ii) determine the parameters associated with the aBMD variations. Bone turnover markers, sclerostin, periostin and semaphorin 4D were assessed before and 1, 12 and 24 months after SG, and aBMD was determined by DXA at baseline and after 12 and 24 months in 83 patients with obesity. Bone turnover increased from 1 month, peaked at 12 months and remained elevated at 24 months. Periostin and sclerostin presented only modest increases at 1 month, whereas semaphorin 4D showed increases only at 12 and 24 months. A significant aBMD decrease was observed only at total hip regions at 12 and 24 months. This demineralisation was mainly related to body weight loss. In summary, reduced aBMD was observed after SG in the hip region (mechanical-loading bone sites) due to an increase in bone turnover in favour of bone resorption. Periostin, sclerostin and semaphorin 4D levels varied after SG, showing different time lags, but contrary to weight loss, these biological parameters did not seem to be directly implicated in the skeletal deterioration.

Classification of Slippage Following Laparoscopic BariClip Gastroplasty.

INTRODUCTION: Laparoscopic BariClip gastroplasty (LBCG) is a new reversible gastric sleeve-like procedure without gastrectomy proposed to minimize the risk of severe complications. Still one of the possible complications described with LBCG is slippage. The purpose of the current manuscript is to analyze different cases of slippage and propose a classification of this complication. METHODS: A number of 381 patients who underwent LBCG in 8 different centers were analyzed concerning the risk of slippage. All cases with documented slippage were carefully reviewed in terms of patients' symptomatology (presence of satiety, vomiting), history of weight loss, radiological data, and management of their slippage. A new classification was proposed depending on the anatomy, the symptomatology, and the time of occurrence. RESULTS: We have identified a total of 17 cases (4.46%) of slippage following LBCG. In 11 patients, the slippage was symptomatic with repetitive vomiting and nausea, and in the remaining 6 patients, the slippage was identified by radiological studies for insufficient weight loss, weight regain, or routine radiological follow-up. Depending on the interval time, the slippage was classified as either immediate (in first 7 days) in 6 cases, early (in less than 90 days) in 4 cases, and late (after 3 months) in 7 cases. Evaluation of the radiological studies in these cases identified the following: anterosuperior displacement (type A) in 9 cases, posteroinferior displacement (type B) in 6 cases (one case after 3 months), and lateral displacement (type C) in the remaining 2 cases. The management of the slippage consisted of BariClip removal in 7 cases, repositioning in 5 cases, and conservative treatment in the remaining 5 cases. All patients with conservative treatment were recorded at the beginning of the experience. CONCLUSIONS: Slippage is a possible complication after LBCG. This classification of the different types of slippage can benefit the surgeon in the management and treatment of this complication of LBCG.

Long-Term Results After Bariatric Surgery in Super-Super-Obese Patients.

Introduction: Despite addressing to high risk population, we can propose laparoscopic bariatric surgery to super-super-obese (SSO) patients (body mass index [BMI] ≥60 kg/m2). The aim of this study was to report our experience in terms of weight loss and improvement of medical comorbidities after a follow-up of 5 years in the SSO population who underwent different bariatric procedures. Methods: This retrospective study includes all SSO patients who underwent bariatric surgery (sleeve gastrectomy [SG] and/or gastric bypass) between 2006 and 2017. The population was divided in three groups (SG alone; Roux-en-Y gastric bypass [RYGB] alone and SG+RYGB). The rate of complication and the weight-loss results were analyzed. Results: Among 43 patients who underwent surgery, the mean age was 42[31-54]. There were more women (72%) with the mean preoperative BMI of 64.9 kg/m2 [59.6-70.1]. There were 9 SGs, 26 RYGB, and 8 SG revised to gastric bypass (SG+RYGB) after a median delay of 23.5 months [16.5-32]. The perioperative complication rate was 25%, and there was 1 postoperative death. The median follow-up was 69 months [1-128]. The mean percentage of excess weight loss (%EWL) was 39.2% [18.2-60.3] after 5 years. For the SG group, the %EWL was inferior -27.1 [-3.6 to 57.8], but with no significant difference. An improvement of comorbidities' rate was recorded in all groups of patients. Conclusion: Bariatric surgery in SSO patients leads to an improvement of comorbidities even if the weight-loss results, especially in the SG group, are less favorable. The two steps approach should be re-evaluated by shortening the interval between. Other surgical strategies than RYGB are needed to be evaluated to improve long-term weight loss.

A Video-Based Review of Important Technical Concepts in the Nissen-Sleeve Gastrectomy.

PURPOSE: The development of gastroesophageal reflux disease (GERD) is a commonly encountered scenario after sleeve gastrectomy. A recently reported technical amendment to incorporate a Nissen fundoplication is discussed in this multimedia article focussing on optimising outcomes and reducing complications. MATERIALS AND METHODS: An intraoperative video has been edited to demonstrate the Nissen-Sleeve Gastrectomy and important technical considerations in its technical performance. RESULTS: Gastrolysis is performed proximally from 6 cm proximal to the pylorus. Routine full mediastinal mobilisation of the oesophagus (5 cm) is completed. Cruroplasty is routinely performed. A short Nissen fundoplication is completed calibrated on a 37 French bougie and then sleeve gastrectomy is performed. Our team's experience suggests that careful manipulation of the fundus and using reproducible measurements of the fundus are key to completing the fundoplication whilst minimising complications. A control test with mobilisation of the bougie through the wrap is recommended at the end of the procedure. CONCLUSION: The Nissen-Sleeve Gastrectomy, as presented in this video, is safe and has good short-term efficacy outcomes. Longer term and randomised studies are ongoing.

Prevalence of Overweight and Obesity in France: The 2020 Obepi-Roche Study by the "Ligue Contre l'Obésité".

Obepi-Roche 2020 by the "Ligue Contre l'Obésité" (League Against Obesity) estimated overweight and obesity prevalence in France. The adopted methodology was chosen to be as similar as possible to that of a series of quota-based surveys conducted every three years from 1997 to 2012 (Obepi-Roche studies). The 2020 survey was conducted online from 24th September to 5th October 2020 by the Odoxa polling institute on a sample of metropolitan French subjects aged 18 years or over. Participants (n = 9598) self-measured their height and weight according to detailed instructions. Prevalence estimates were produced for all categories of body mass index. The prevalence of excess weight was 47.3% (17.0% of subjects with obesity), with higher values in the north and east of France. When comparing these 2020 estimates to previous Obepi-Roche estimates in order to visualize trends since 1997, it appeared that overweight fluctuated around 30%, and obesity prevalence increased steadily at a rapid pace. The increase was even steeper in the youngest age groups and for severe and complex obesity. Given the slightly different methodologies between the 1997-2012 studies and the 2020 survey, the worrying trends in obesity prevalence since 1997 must be confirmed, calling for a reedition of the Obepi-Roche series.

Evolving Technique of Laparoscopic Vertical Gastric Clip Placement.

INTRODUCTION: Laparoscopic BariClip gastroplasty (LBCG) will address a similar tubular restriction than the one achieved with the laparoscopic sleeve gastrectomy (LSG) at the level of the gastric fundus, while maintaining the advantage of simplicity and anatomic preservation. The purpose of the current study was to analyze the risk of slippage and to present the evolving technique by adding gastro-gastric plication of the gastric wall covering the BariClip at those areas where the gastric wall "slips" between the limbs of the clip. METHODS: All patients undergoing LBCG with the evolving technique of gastric plication around the device associated with antral gastroplasty from January 2021 to May 2022 were included in the study group (group A). A control group (group B) was designed with patients who underwent previous LBCG technique between May 2017 and June 2019. This is a case-controlled group with patients matched by gender and BMI. We have analyzed the postoperative complications and more notably the slippage. RESULTS: One hundred seventy-six patients (44 male and 132 female) with a mean age of 33 years (± 11) underwent evolving technique of LBCG. A control group of 67 patients who underwent previous technique of LBCG was included. All procedures were completed by laparoscopy with no intraoperative complication. For the study group, we have recorded a number of 5 slippages (2.8%). The diagnosis occurred during the first 6 months after the operation. The management consisted of repositioning-3 cases-and BariClip removal-2 cases. For the control group, we have recorded a number of 3 slippages (4.3%). All three patients underwent BariClip removal, with no repositioning. CONCLUSIONS: We reported a new technique of placement of the BariClip with additional gastric plication anterior, posterior, and volume reduction in the antrum to potentially reduce the rate of slippage and improve weight loss outcomes.

Is the Surgical Drainage Mandatory for Leak after Sleeve Gastrectomy?

INTRODUCTION: Despite the unanimous acknowledgement of the laparoscopic sleeve gastrectomy (LSG) worldwide, the leak remains its deficiency. For the last decade, the surgical treatment was practically considered mandatory for almost any collection following LSG. The aim of this study is to evaluate the need for surgical drainage for leak following LSG. METHODS: All consecutive patients having gone through LSG from January 2017 to December 2020 were enrolled in our study. Once the demographic data and the leak history were registered, we analyzed the outcome of the surgical or endoscopic drainage, the characteristics of the endoscopic treatment, and the evolution to complete healing. RESULTS: A total of 1249 patients underwent LSG and the leak occurred in 11 cases (0.9%). There were 10 women with a mean age of 47.8 years (27-63). The surgical drainage was performed for three patients and the rest of the eight patients underwent primary endoscopic treatment. The endoscopic treatment was represented with pigtails for seven cases and septotomy with balloon dilation for four cases. In two out of these four cases, the septotomy was anticipated by the use of a nasocavitary drain for 2 weeks. The average number of endoscopic procedures was 3.2 (range 2-6). The leaks achieved complete healing after an average duration of 4.8 months (range 1-9 months). No mortality was recorded for a leak. CONCLUSIONS: The treatment of the gastric leak must be tailored to each patient. Although there is still no consensus for the endoscopic drainage of leaks after LSG, the surgical approach can be avoided in up to 72%. The benefits of pigtails and nasocavitary drains followed by endoscopic septotomy are undeniable, and they should be included in the armamentarium of any bariatric center.

Endoscopic Gastric Band Removal.

BACKGROUND: Laparoscopic adjustable gastric band (LAGB) procedures have declined worldwide in recent years. A known complication is the intraluminal erosion of the prosthetic material. The endoscopic management of gastric band erosion represents the recommended approach nowadays, and it avoids any additional trauma to the gastric wall already damaged by the migration. The purpose of our study was to assess the feasibility of endoscopic management for intraluminal gastric band erosion following LAGB. METHODS: From January 2009-December 2020, a total of 29 patients were retrospectively reviewed after undergoing endoscopic gastric band removal. The study included all consecutive patients who underwent endoscopic gastric band removal in this period. No patients were excluded from the study. Data on patient demographic characteristics, case history, operative details (procedural time, adverse events), and complications were reviewed retrospectively. RESULTS: Twenty-nine patients underwent endoscopic gastric band removal: 22 women (75.8%) with a mean age of 45 years (range: 28-63) and mean Body Mass Index (BMI) of 31 ± 4.7 kg/m2 (range: 24-41). The average time to the identification of erosion after LAGB was 42 months (range: 28-137). The initial upper endoscopy found a migrated band of more than half of the diameter in 21 cases, less than a half but more than a third in seven cases and in one case, less than a third (use of a stent). Twenty-seven patients were successfully treated with endoscopic removal, and in two cases, the endoscopic approach failed, and laparoscopy was further performed. CONCLUSIONS: The endoscopic management of intraluminal erosion after LAGB can be safe and effective and should be considered the procedure of choice when treating this complication. The percentage of the band migration is important for the timing of the endoscopic removal.

The Reflux and BariClip: Initial Results and Mechanism of Action.

INTRODUCTION: Laparoscopic BariClip Gastroplasty (LBCG) represents a new bariatric procedure that mimics the principle of the Laparoscopic Sleeve Gastrectomy (LSG), but using a completely reversible mechanism, which is essential for gastroesophageal reflux disease (GERD). The purpose of our study was to evaluate the evolution of GERD following the initial experience with LBCG. METHODS: The first 43 obese patients who underwent LBCG performed by the same surgeon in two different medical centers in May 2018-December 2019 were included in the current study. Twelve patients had issues of reflux, regularly receiving PPIs (proton pump inhibitors) treatment in eight cases, and occasionally in four cases. Thirty-two patients completed the follow-up at one year and the GERD was evaluated using the PPI medications and the GerdQ. RESULTS: The median preoperative GerdQ score was (14.58 ± 1.9). Three patients out of the twelve who had complained about preoperative GERD did not consent to the one year follow-up form. For the rest of nine patients, the median post-operative GerdQ score was (10.11 ± 3.2). The PPIs were used at one year follow-up in six patients: four with occasional use, one patient with regular use showing no improvement, and one who experienced de novo GERD symptomatology (3.1%). No statistically significant difference between the groups was recorded in terms of GERD. We recorded no intraoperative complications. No case of erosion occurred in the post-operative period, but we encountered two cases of slippage. One additional BariClip was removed at 14 months. CONCLUSION: LBCG represents a new bariatric procedure that mimics the principle of the laparoscopic sleeve gastrectomy, but with a completely reversible mechanism. Even with limited cases, our experience reports several mechanisms of action that will be evaluated and discussed in further prospective clinical trials. After this preliminary clinical study, LBCG's effects on GERD and its safety are highly encouraging.

Resizing of the Gastric Pouch for Weight Regain after Laparoscopic Roux-en-Y Gastric Bypass and One-Anastomosis Gastric Bypass: Is It a Valid Option?

Introduction: The laparoscopic resizing of the gastric pouch (LPR) has recently been proposed as a revisional technique in the case of weight regain (WR) after gastric bypass procedures. The aim of this study was to report our experience with LPR for WR. Materials and Methods: All patients with WR ≥ 25% after gastric bypass and with a dilated gastric pouch and/or gastrojejunal anastomosis who underwent LPR between January 2017 and January 2022 were retrospectively reviewed. From a radiological point of view, a gastric pouch was considered dilated when its volume was calculated at >80 cm3 for LRYGB and >200 cm3 for OAGB upon a 3D-CT scan. The endoscopic criterion considered both the diameter of the gastrojejunal anastomosis and the gastric pouch volume. All anastomoses > 20 mm for LRYGB and >40 mm for OAGB were considered dilated, while a gastric pouch was considered endoscopically dilated when the retrovision maneuver with the gastroscope was easily performed. These selection criteria were arbitrarily established on the basis of both our personal experience and literature data. Results: Twenty-three patients had LPR after a Roux-en-Y gastric bypass or one-anastomosis gastric bypass. The mean BMI at LPR was 36.3 ± 4.7 kg/m2. All patients underwent LPR, while the resizing of the GJA was also performed in 3/23 (13%) cases, and hiatoplasty was associated with the resizing of the pouch in 6/23 cases (26.1%). The mean BMI at the last follow-up was 29.3 ± 5.8 kg/m2. The difference between the BMI before resizing and the BMI at the last follow-up visit was statistically significant (p = 0.00005). The mean %TWL at 24.2 ± 16.1 months was 19.6 ± 9%. Comorbidities had an overall resolution and/or improvement rate of 47%. The mean operative time was 71.7 ± 21.9 min. The conversion rate was nil. Postoperative complications occurred in two cases (8.7%). Conclusions: In our series, LPR for WR showed good results in weight loss and in improvement/resolution of comorbidities, with an acceptable complication rate and operative time. Only further studies with a greater cohort of patients and a longer postoperative follow-up will be able to highlight the long-term benefits of this technique.

The Utility of Video Recording in Assessing Bariatric Surgery Complications.

INTRODUCTION: Recording every procedure could diminish the postoperative complication rates in bariatric surgery. The aim of our study was to evaluate the correlation between recording every bariatric surgery and their postoperative analysis in relation to the early or late postoperative complications. METHODS: Seven hundred fifteen patients who underwent a bariatric procedure between January 2018 and December 2019 were included in a retrospective analysis. There were: 589 laparoscopic sleeve gastrectomies (LSGs); 110 Roux-en-Y bypasses (RYGBs) and 16 gastric bands (LAGBs). The video recording was systematically used, and all patients were enrolled in the IFSO registry. RESULTS: There were 15 patients (2.1%) with surgical postoperative complications: 5 leaks, 8 hemorrhages and 2 stenosis. Most complications were consequent to LSG, except for two, which occurred after RYGB. In four cases a site of active bleeding was identified. After reviewing the video, in three cases the site was correlated with an event which occurred during the initial procedure. Three out of five cases of leak following sleeve were treated purely endoscopically, and no potential correlated mechanism was identified. Two other possible benefits were observed: a better evaluation of the gastric pouch for the treatment of the ulcer post bypass and the review of one per operative incident. Two negative diagnostic laparoscopies were performed. The benefit of the systematic video recording was singled out in eight cases. All the other cases were completed by laparoscopy with no conversion. CONCLUSION: To record every bariatric procedure could help in understanding the mechanism of certain complications, especially when the analysis is performed within the team. Still, recording the procedure did not prevent the negative diagnostic laparoscopy, but it could play a significant role for the medico-legal aspect in the future.
