RESUMEN
BACKGROUND: There is little international data on morbidity and mortality of surgery for perforated peptic ulcer (PPU). This study aimed to understand the global 30-day morbidity and mortality of patients undergoing surgery for PPU and to identify variables associated with these. METHOD: We performed an international study of adults (≥ 18 years) who underwent surgery for PPU from 1st January 2022 to 30th June 2022. Patients who were treated conservatively or had an underlying gastric cancer were excluded. Patients were divided into subgroups according to age (≤ 50 and > 50 years) and time from onset of symptoms to hospital presentation (≤ 24 and > 24 h). Univariate and Multivariate analyses were carried out to identify factors associated with higher 30-day morbidity and mortality. RESULTS: 1874 patients from 159 centres across 52 countries were included. 78.3% (n = 1467) of the patients were males and the median (IQR) age was 49 years (25). Thirty-day morbidity and mortality were 48.5% (n = 910) and 9.3% (n = 174) respectively. Median (IQR) hospital stay was 7 (5) days. Open surgery was performed in 80% (n = 1505) of the cohort. Age > 50 years [(OR = 1.7, 95% CI 1.4-2), (OR = 4.7, 95% CI 3.1-7.6)], female gender [(OR = 1.8, 95% CI 1.4-2.3), (OR = 1.9, 95% CI 1.3-2.9)], shock on admission [(OR = 2.1, 95% CI 1.7-2.7), (OR = 4.8, 95% CI 3.2-7.1)], and acute kidney injury [(OR = 2.5, 95% CI 1.9-3.2), (OR = 3.9), 95% CI 2.7-5.6)] were associated with both 30-day morbidity and mortality. Delayed presentation was associated with 30-day morbidity [OR = 1.3, 95% CI 1.1-1.6], but not mortality. CONCLUSIONS: This study showed that surgery for PPU was associated with high 30-day morbidity and mortality rate. Age, female gender, and signs of shock at presentation were associated with both 30-day morbidity and mortality.

PURPOSE: During the coronavirus disease 19 (COVID-19) outbreak, most public hospitals worldwide have been forced to postpone a major part of bariatric surgery (BS) operations with unfavorable consequences for weight and obesity complications. The aim of this study was to evaluate the effectiveness and safety of laparoscopic BS on subjects with metabolically unhealthy obesity (MUO) during COVID-19 pandemic in a high-volume Italian center. METHODS: Between March 2020 and January 2021, all patients with MUO submitted to laparoscopic BS (sleeve gastrectomy [SG], one anastomosis gastric bypass [OAGB] and Roux-en-Y gastric bypass [RYGB]) were enrolled according to the ATP III Guidelines, with a minimum follow-up of 3 months. RESULTS: In the study period, 210 patients with MUO underwent laparoscopic BS (77 RYGB, 85 SG and 48 OAGB) in our obesity referral center. Postoperative major complications occurred in 4 patients (1.9%) with zero mortality. At 9-month follow-up, a total weight loss (TWL) of 28.2 ± 18.4, 26.1 ± 23.1 and 24.5 ± 11.3% (p = 0.042) was observed in RYGB, OAGB and SG groups, respectively. The rate of comorbidity resolution was very similar for all type of surgeries (p = 0.871). Only two cases of postoperative SARS-CoV-2 infection were registered (0.9%) and both cases resolved with medical therapy and observation. CONCLUSION: Among the patients studied, all surgical techniques were safe and effective for MUO during the COVID era. This group of patients is at high risk for general and SARS-CoV-2-related mortality and therefore should be prioritized for BS. LEVEL OF EVIDENCE: Level III, single-center retrospective cohort study.

INTRODUCTION: Klinefelter syndrome (KS) can appear as a wide spectrum of clinical manifestations, with no guidelines for appropriate treatment. We present the first study of bariatric surgery (BS) with a 48-month follow-up, for the management of two patients affected by obesity and KS. CASES PRESENTATION: The first patient was a 32-year-old man with diagnosis of Klinefelter mosaicism (46 XY/47, XXY), Body Mass Index (BMI) of 50 kg/m2, metabolic syndrome and Binge Eating Disorder (BED). He underwent a Laparoscopic Sleeve Gastrectomy (LSG) with weight loss (BMI = 38 kg/m2) and improvements to his metabolic profile at 48 months. The second patient was a 44-year-old man with KS (47, XXY), BMI of 49 kg/m2, Obstructive Sleep Apnea Syndrome and BED. He underwent a banded LSG. After 48 months, he showed a satisfactory weight loss (BMI = 32 kg/m2) and amelioration of comorbidities. CONCLUSION: In patients with KS, LSG demonstrated long-term beneficial effects for weight loss and amelioration of comorbidities. An interdisciplinary approach is mandatory, since it leads to adherence to follow-up programs and mental health well-being.

PURPOSE: Pre-surgical psychosocial evaluation of bariatric surgery (BS) patients should identify psychiatric issues that could worsen after surgery and those requiring additional ongoing intervention. In this view, the use of reliable, appropriate and concise evaluating instruments is of critical importance. The aim of the present study was to investigate the clinical utility of both the Symptom Checklist 90-Revised (SCL-90-R) and its brief unidimensional version, the so-called Symptom-Checklist-K-9 (SCL-K-9) in detecting the presence of psychiatric disorders among bariatric surgery (BS) candidates. METHODS: Seven-hundred-and-ninety-eight BS candidates (563 women and 235 men; mean age: 44.15 ± 11.45) were enrolled in the present study. All participants underwent a full psychiatric interview and were administered the SCL-90-R. RESULTS: Three-hundred-and-sixty-two patients (45.4%) met the criteria for a diagnosis of at least one psychiatric disorder and ninety-nine patients (12.4%) had psychiatric comorbidities. In the current sample, 219 patients (27.4%) met the criteria for binge eating disorders (BED), 158 (19.8%) met the criteria for major depressive disorder (MDD), and 67 (8.4%) met both criteria. A receiver operating characteristic (ROC) curves procedure showed that both the SCL-90-R and the SCL-K-9 satisfactorily categorize patients with any psychiatric disorder, both BED and MDD (area under the ROC curve ≥ 0.70, p < 0.001). CONCLUSION: Our results suggest that the SCL-90-R and the SCL-K-9 may represent first-level screening tests identifying at-risk patients, eligible for a more expensive or time-consuming clinical assessment. LEVEL OF EVIDENCE: Level V, cross-sectional, descriptive study.

Obesity represents one of the most complex public health challenges and has recently reached epidemic proportions. Obesity is also considered to be primarily responsible for the rising prevalence of metabolic syndrome, defined as the coexistence in the same individual of several risk factors for atherosclerosis, including dyslipidemia, hypertension and hyperglycemia, as well as for cancer. Additionally, the presence of three of the five risk factors (abdominal obesity, low high-density lipoprotein cholesterol, high triglycerides, high fasting glucose and high blood pressure) characterizes metabolic syndrome, which has serious clinical consequences. The current study was conducted in order to identify metabolic differences in visceral adipose tissue (VAT) collected from obese (body mass index 43-48) human subjects who were diagnosed with metabolic syndrome, obese individuals who were metabolically healthy and nonobese healthy controls. Extensive gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS/MS) analyses were used to obtain the untargeted VAT metabolomic profiles of 481 metabolites belonging to all biochemical pathways. Our results indicated consistent increases in oxidative stress markers from the pathologically obese samples in addition to subtle markers of elevated glucose levels that may be consistent with metabolic syndrome. In the tissue derived from the pathologically obese subjects, there were significantly elevated levels of plasmalogens, which may be increased in response to oxidative changes in addition to changes in glycerolphosphorylcholine, glycerolphosphorylethanolamine glycerolphosphorylserine, ceramides and sphingolipids. These data could be potentially helpful for recognizing new pathways that underlie the metabolic-vascular complications of obesity and may lead to the development of innovative targeted therapies.

INTRODUCTION: Revisional bariatric surgery (RBS) for insufficient weight loss/weight regain or metabolic relapse is increasing worldwide. There is currently no large multinational, prospective data on 30-day morbidity and mortality of RBS. In this study, we aimed to evaluate the 30-day morbidity and mortality of RBS at participating centres. METHODS: An international steering group was formed to oversee the study. The steering group members invited bariatric surgeons worldwide to participate in this study. Ethical approval was obtained at the lead centre. Data were collected prospectively on all consecutive RBS patients operated between 15th May 2021 to 31st December 2021. Revisions for complications were excluded. RESULTS: A total of 65 global centres submitted data on 750 patients. Sleeve gastrectomy (n = 369, 49.2 %) was the most common primary surgery for which revision was performed. Revisional procedures performed included Roux-en-Y gastric bypass (RYGB) in 41.1 % (n = 308) patients, One anastomosis gastric bypass (OAGB) in 19.3 % (n = 145), Sleeve Gastrectomy (SG) in 16.7 % (n = 125) and other procedures in 22.9 % (n = 172) patients. Indications for revision included weight regain in 615(81.8 %) patients, inadequate weight loss in 127(16.9 %), inadequate diabetes control in 47(6.3 %) and diabetes relapse in 27(3.6 %). 30-day complications were seen in 80(10.7 %) patients. Forty-nine (6.5 %) complications were Clavien Dindo grade 3 or higher. Two patients (0.3 %) died within 30 days of RBS. CONCLUSION: RBS for insufficient weight loss/weight regain or metabolic relapse is associated with 10.7 % morbidity and 0.3 % mortality. Sleeve gastrectomy is the most common primary procedure to undergo revisional bariatric surgery, while Roux-en-Y gastric bypass is the most commonly performed revision.

BACKGROUND: No robust data are available on the safety of primary bariatric and metabolic surgery (BMS) alone compared to primary BMS combined with other procedures. OBJECTIVES: The objective of this study is to collect a 30-day mortality and morbidity of primary BMS combined with cholecystectomy, ventral hernia repair, or hiatal hernia repair. SETTING: This is as an international, multicenter, prospective, and observational audit of patients undergoing primary BMS combined with one or more additional procedures. METHODS: The audit took place from January 1 to June 30, 2022. A descriptive analysis was conducted. A propensity score matching analysis compared the BLEND study patients with those from the GENEVA cohort to obtain objective evaluation between combined procedures and primary BMS alone. RESULTS: A total of 75 centers submitted data on 1036 patients. Sleeve gastrectomy was the most commonly primary BMS (N = 653, 63%), and hiatal hernia repair was the most commonly concomitant procedure (N = 447, 43.1%). RYGB accounted for the highest percentage (20.6%) of a 30-day morbidity, followed by SG (10.5%). More than one combined procedures had the highest morbidities among all combinations (17.1%). Out of overall 134 complications, 129 (96.2%) were Clavien-Dindo I-III, and 4 were CD V. Patients who underwent a primary bariatric surgery combined with another procedure had a pronounced increase in a 30-day complication rate compared with patients who underwent only BMS (12.7% vs. 7.1%). CONCLUSION: Combining BMS with another procedure increases the risk of complications, but most are minor and require no further treatment. Combined procedures with primary BMS is a viable option to consider in selected patients following multi-disciplinary discussion.
RESUMEN
OBJECTIVE: Tissue inhibitor of metalloproteinase 3 (TIMP3) is a stromal protein that inhibits the activity of proteases and receptors. TIMP3 is downregulated in metabolic and inflammatory disorders, such as type 2 diabetes mellitus and atherosclerosis, particularly in regions enriched with monocyte/macrophage cells. To investigate the role of TIMP3 in atherosclerosis, we generated a new mouse model in which Timp3 was overexpressed in the atherosclerotic plaque via a macrophage-specific promoter (MacT3). We elucidated any potential antiatherosclerotic effects of TIMP3, including regulation of monocyte/macrophage recruitment within atherosclerotic plaques, in MacT3 mice crossbred with low-density lipoprotein receptor knockout (LDLR(-/-)) mice. METHODS AND RESULTS: MacT3/LDLR(-/-) mice had an improvement of atherosclerosis and metabolic parameters compared with LDLR(-/-). En face aorta and aortic root examination of MacT3/LDLR(-/-) mice revealed smaller atherosclerotic plaques with features of stability, such as increased collagen content and decreased necrotic core formation. Atherosclerotic plaques in MacT3/LDLR(-/-) mice contained fewer T cells and macrophages. Furthermore, TIMP3 overexpression in macrophages resulted in reduced oxidative stress signals, as evidenced by lower lipid peroxidation, protein carbonylation, and nitration in atheromas. CONCLUSIONS: Our study confirmed that macrophage-specific overexpression of TIMP3 decreases the inflammatory content and the amplitude of atherosclerotic plaques in mice.

PURPOSE: Sleeve gastrectomy, the most commonly performed bariatric surgery procedure, carries limitations both short term including postoperative complications such as hemorrhage and gastric fistula and long term such as weight regain and gastroesophageal reflux. A new procedure has been proposed to overcome many of these limitations: laparoscopic vertical clip gastroplasty (LVCG) with BariClip. MATERIALS AND METHODS: Fifty patients were offered LVCG and enrolled for a feasibility study in two referral bariatric centers. Indication was given as for sleeve gastrectomy, after a multidisciplinary path evaluating age, gender, BMI, comorbidities, eating behaviors, and gastroesophageal reflux. The primary outcome was major postoperative complications. Secondary outcomes included weight loss, incidence of de-novo GERD, and comorbidity resolution. RESULTS: Patients had a mean age of 44 years and mean BMI of 37 kg/m2 ± 6.2. All procedures were performed successfully in laparoscopy, with no conversion or intraoperative adverse events. The overall major postoperative complication rate was 6%. Re-operation was required in three patients for slippage. No mortality occurred. Excess weight loss, excess BMI loss, and total weight loss at 6 months were 36%, 57%, and 22%, respectively. There was no instance of de-novo GERD. Resolution of hypertension occurred in 50% of cases, OSAS in 65% of cases, and DMII in 80% of cases. CONCLUSION: The safety of LVCG procedure has been reproduced in a multicentric, multi-surgeon study. Weight loss outcomes appear promising. A randomized trial is needed to fully assess the benefits of LVCG.

BACKGROUND: Bariatric surgery (BS) is a relatively novel surgical field and is in continuous expansion and evolution. PURPOSE: Aim of this study was to report changes in Italian surgical practice in the last decade. METHODS: The Società Italiana di Chirurgia dell'Obesità (SICOB) conducted annual surveys to cense activity of SICOB centers between 2011 and 2021. Primary outcome was to detect differences in frequency of performance of adjustable gastric banding (AGB), sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), one anastomosis gastric bypass (OAGB), bilio-pancreatic diversion (BPD), and gastric plication (GP). Secondary outcome was to detect differences in performance of main non-malabsorptive procedures (AGB + SG) and overall bypass procedures (RYGB + OAGB). Geographical differences were also investigated. RESULTS: Median response rate was 92%. AGB declined from 36% of procedures in 2011 to 5% in 2021 (p < 0.0001). SG increased from 30% in 2011 to 55% in 2021 (p < 0.0001). RYGB declined from 25 to 12% of procedures (p < 0.0001). OAGB rose from 0% of procedures in 2011 to 15% in 2021 (p < 0.0001). BPD underwent decrease from 6.2 to 0.2% in 2011 and 2021, respectively (p < 0.0001). Main non-malabsorptive procedures significantly decreased while overall bypass procedures remained stable. There were significant differences among regions in performance of SG, RYGB, and OAGB. CONCLUSIONS: BS in Italy evolved significantly during the past 10 years. AGB underwent a decline, as did BPD and GP which are disappearing and RYGB which is giving way to OAGB. The latter is rising and is the second most-performed procedure after SG which has been confirmed as the preferred procedure by Italian bariatric surgeons.

BACKGROUND: Revisional bariatric surgery (RBS) represents a further solution for patients who experience inadequate weight loss (IWL) following primary bariatric surgery (BS) or significant weight regain (WR) following initial satisfactory response. RBS guidelines are lacking; however, an increased trend in further BS offerings has been reported recently. OBJECTIVE: Analyze trend, mortality, complication, readmission, and reoperation rates for any reason at 30 days after RBS in Italy. SETTING: Ten Italian high-volume BS centers (university hospitals and private centers). METHODS: Prospective, observational, multicenter study enrolling patients undergoing RBS between October 1, 2021, and March 31, 2022, registering reasons for RBS, technique, mortality, intraoperative and perioperative complications, readmissions, and reinterventions for any reason. Patients undergoing RBS during the same calendar interval in 2016-2020 were considered control patients. RESULTS: A total of 220 patients were enrolled and compared with 560 control-group patients. Mortality was .45% versus .35% (n.s), with an overall mortality of .25%, while open surgery or conversion to open surgery was registered in 1%. No difference was found for mortality, morbidity, complications, readmission (1.3%), and reoperation rates (2.2%). IWL/WR was the most frequent cause, followed by gastroesophageal reflux disease; Roux-en-Y gastric bypass was the most used revisional procedure (56%). Sleeve gastrectomy was the most revised procedure in the study group, while gastric banding was the most revised in the control group. RBS represents up to 9% of the total BS in the Italian participating centers. CONCLUSIONS: Laparoscopy represents the standard approach for RBS, which appears safe. Current Italian trends show a shift toward sleeve gastrectomy being the most revised procedure and Roux-en-Y gastric bypass being the most frequent revisional procedure.
RESUMEN
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.

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.

This study aims to compare different types of metabolic bariatric surgery (MBS) with lifestyle intervention/medical therapy (LSI/MT) for the treatment of overweight/obesity. The present and network meta-analysis (NMA) includes randomized trials. MBS was associated with a reduction of BMI, body weight, and percent weight loss, when compared to LSI/MT, and also with a significant reduction of HbA1c and a higher remission of diabetes. Meta-regression analyses revealed that BMI, a higher proportion of women, and a longer duration of trial were associated with greater effects of MBS. The NMA showed that all surgical procedures included (except greater curvature plication) were associated with a reduction of BMI. MBS is an effective option for the treatment of obesity. The choice of BMI thresholds for eligibility for surgery of patients with different complications should be performed making an evaluation of risks and benefits in each BMI category.

In patients with the metabolic syndrome (MetS), the facilitatory effect of insulin on forearm vasodilator responsiveness to different stimuli is impaired. Whether the RhoA/Rho kinase (ROCK) pathway is involved in this abnormality is unknown. We tested the hypotheses that, in MetS patients, ROCK inhibition with fasudil restores insulin-stimulated vasodilator reactivity and that oxidative stress plays a role in this mechanism. Endothelium-dependent and -independent forearm blood flow responses to acetylcholine (ACh) and sodium nitroprusside (SNP), respectively, were assessed in MetS patients (n = 8) and healthy controls (n = 5) before and after the addition of fasudil (200 µg/min) to an intra-arterial infusion of insulin (0.1 mU/kg/min). In MetS patients (n = 5), fasudil was also infused without hyperinsulinemia. The possible involvement of oxidative stress in the effect of fasudil during hyperinsulinemia was investigated in MetS patients (n = 5) by infusing vitamin C (25 mg/min). In MetS patients, compared with saline, fasudil enhanced endothelium-dependent and -independent vasodilator responses during insulin infusion (P < 0.001 and P = 0.008, respectively), but not in the absence of hyperinsulinemia (P = 0.25 and P = 0.13, respectively). By contrast, fasudil did not affect vasoreactivity to ACh and SNP during hyperinsulinemia in controls (P = 0.11 and P = 0.56, respectively). In MetS patients, fasudil added to insulin and vitamin C did not further enhance vasodilation to ACh and SNP (P = 0.15 and P = 0.43, respectively). In the forearm circulation of patients with the MetS, ROCK inhibition by fasudil improves endothelium-dependent and -independent vasodilator responsiveness during hyperinsulinemia; increased oxidative stress seems to be involved in the pathophysiology of this phenomenon.

BACKGROUND: The main drawback of laparoscopic sleeve gastrectomy (LSG) is the severity of postoperative complications. Staple line reinforcement (SLR) is strongly advocated. The purpose of this study was to compare prospectively and randomly three different techniques of SLR during LSG. METHODS: From April 2010 to April 2011, patients submitted to LSG were randomly selected for the following three different techniques of SLR: oversewing (group A); buttressed transection with a polyglycolide acid and trimethylene carbonate (group B); and staple-line roofing with a gelatin fibrin matrix (group C). Primary endpoints were reinforcement operative time, incidence of postoperative staple-line bleeding, and leaks. Operative time was calculated as follows: oversewing time in group A; positioning of polyglycolide acid and trimethylene carbonate over the stapler in group B; and roofing of the entire staple line in group C. RESULTS: A total of 120 patients were enrolled in the study (82 women and 38 men). Mean age was 44.6 ± 9.2 (range, 28-64) years. Mean preoperative body mass index was 47.2 ± 6.6 (range, 40-66) kg/m². Mean time for SLR was longer in group A (14.2 ± 4.2 (range, 8-18) minutes) compared with group B (2.4 ± 1.8 (range, 1-4) minutes) and group C (4.4 ± 1.6 (range, 3-6) minutes; P < 0.01). Four major complications were observed (3.3 %): one leak and one bleeding in group A; one bleeding in group B; and one leak in group C, with no significant differences between the groups. No mortality was observed. CONCLUSIONS: SLR with either polyglycolide acid with trimethylene carbonate or gelatin fibrin matrix is faster compared with oversewing. No significant differences were observed regarding postoperative staple-line complications.

Bariatric surgery (BS) is the most effective treatment in reducing weight and the burden of comorbidities in patients with severe obesity. Despite the overall low mortality rate, intra- and post-operative complications remains quite common. Weight loss before BS reduces surgical risk, but studies are inconclusive regarding which is the best approach to apply. In this review, we summarize the current evidence on the effect of a ketogenic diet (KD) before BS. All studies agree that KD leads to considerable weight loss and important improvements in terms of surgical risk, but populations, interventions and outcomes are very heterogeneous. KD appears to be a safe and effective approach to induce weight loss before BS. However, randomized controlled trials with better-defined dietary protocols and homogeneous outcomes are necessary in order to draw firm conclusions.

Background: In the last 2 years, anorectal surgery has been strongly affected and even surgery for urgent cases cannot be scheduled; also, patients with III- and IV-degree bleeding hemorrhoids should be treated conservatively. The aim was to evaluate the effectiveness of sclerotherapy in patients who had to postpone surgery. Methods: We included all patients with III- and IV-degree bleeding hemorrhoids who underwent outpatient sclerotherapy. The visual analog scale and the hemorrhoid severity score were used at the baseline and at 4 weeks after the procedure with a telephone interview, and all patients were outpatient-evaluated 1 week, 1 month, and 1 year after the treatment. All pre- and postoperative data were recorded. Results: From October 2020 to November 2021, 19 patients with III- (12 patients; 63%) and IV-degree (7 patients; 37%) bleeding hemorrhoids were enrolled. The mean operative time was 4.5â min, and no intraoperative complications occurred. One case of tenesmus and three failures were detected. Six months after the procedure, the overall success rate was 84%, although all of the patients enrolled reported persistent bleeding at the end of the study period. Of these, 5 patients (26%) were scheduled for surgery and 11 patients (58%) refused surgery and asked to undergo a re-do sclerotherapy. Conclusion: Sclerotherapy with 3% polidocanol foam is a safe and effective procedure also in III- and IV-degree bleeding hemorrhoids. The long-term data on the length of the foam remain to be evaluated in additional studies.
RESUMEN
The correlations between morbid obesity, bariatric surgery and gastrointestinal disorders are well known and reported. Symptoms like abdominal pain, constipation, bloating, heartburn and gastroesophageal reflux disease are known to be significantly more prevalent in overweight patients and body mass index is associated positively with abdominal pain and diarrhea. In spite of these conditions, less is known about the lower gastrointestinal tract. Of these, anorectal disorders and pelvic floor disease are both believed to be more frequent in obese patients compared to the general population. Weight loss related to bariatric surgery seems to improve quality of life and weight-related symptoms, although some of these conditions may get worse. All these conditions are rarely studied in patients undergoing bariatric surgery for morbid obesity. This concise review aimed to focus on these conditions in patients undergoing bariatric surgery for morbid obesity in order to improve patient selection and post-operative management.
RESUMEN
INTRODUCTION: Laparoscopic one anastomosis gastric bypass (LOAGB) is a relatively new procedure for the treatment of morbid obesity and related comorbidities. On average, this procedure results in good postoperative weight loss with a low complication rate. Recent publications suggest that dumping syndrome and weight regain might be reduced by placing a silicone ring over the gastric pouch during the procedure, so called laparoscopic banded one anastomosis gastric bypass (LBOAGB). METHODS: 86 patients undergoing LBOAGB between 2018 and 2020 were enrolled in this retrospective study. Hospital records were used to assess weight loss, comorbidity resolution, and any complications either in the short or medium term. RESULTS: 54 Female and 32 male patients were included with a mean age of 43 years (25-64), preoperative body mass index of 42 kg/m2 (35-49), and preoperative weight of 114 kg (86-162). Thirty-four patients presented with type 2 diabetes (39.5%), 42 patients (49%) diagnosed with hypertension, 24 presented with OSAS (28%), and 21 (24%) hypercholesterolaemia patients were included. In total, 36 patients were diagnosed with multiple comorbidities. The operative data showed an average operative time of 48 minutes with 3.4% of patients suffering from early (minor) complications and 2.3% with a late (minor) complication. One patient required reoperation due to intra-abdominal bleeding. The median length of hospital stay was 2.5 days. Median follow-up was 18 months (5-36). In that period, no patient required ring removal or conversion to Roux-en-Y gastric bypass surgery. Food intolerance/vomiting was present in 1 patient (1.1%), bile reflux was present in 1 patient (1.1%), and no stomal ulcers were observed. Mean % excess weight loss at 12 and 24 months was 72% and 80%, respectively. Fifty-two out of 86 patients (60%) had a complete resolution of comorbidities. A CONUT score >2 (mild malnutrition) was found in 40% of patients, while a CONUT score 0-1 was found in 60% of patients. CONCLUSION: LBOAGB shows promising results in terms of safety and efficacy in the short term. Further prospective studies will be required to evaluate the consistency of the results in the long term.
