Utilization of Hepatocellular Carcinoma Surveillance Programs in Patients With Cirrhosis: A Systematic Review and Meta-Analysis.

Patients with cirrhosis are advised to undergo hepatocellular carcinoma (HCC) surveillance every 6 months. Routine surveillance is associated with early tumor detection and improved survival. However, surveillance is underutilized. We aimed to characterize the uptake of HCC surveillance in cirrhotic patients following the implementation of interventional programs. We performed a comprehensive literature search of major databases (from inception to October 2020). Surveillance was defined as having an abdominal sonogram every 6 months. Nine studies were included for meta-analysis which involved 4550 patients. The etiology of liver cirrhosis was largely due to hepatitis C or B (n=2023), followed by alcohol (n=857), and nonalcoholic steatohepatitis (n=432). Patients enrolled in surveillance programs were 6 times more likely to undergo abdominal sonography when compared with standard of care (odds ratio=6.00; 95% confidence interval: 3.35-10.77). On subgroup analysis, clinical reminders were associated with a 4 times higher rate of HCC surveillance compared with standard of care (odds ratio=3.80; 95% confidence interval: 2.25-6.39). Interventional programs significantly improve the rate of HCC surveillance. This is clinically impactful and should be considered as a means for improving surveillance rates.

Bariatric surgery: to bleed or not to bleed? This is the question.

BACKGROUND: Bariatric surgery procedures are the most successful and durable treatment for morbid obesity. Hemorrhage represents a life-threatening complication, occurring in 1.3-1.7% of bariatric surgeries. MATERIALS AND METHODS: We examined patients undergoing Bariatric Surgery from July 2017 to June 2020 (Group A) and those operated from July 2020 to June 2022 (Group B) in our Department. Starting from July 2020 we have implemented intraoperative measures to prevent postoperative bleeding, increasing mean arterial pressure (MAP) by 30% compared to preoperative and reducing the pneumoperitoneal pressure of CO2 to 8 mmHg in the last 15 min of the operation. RESULTS: The study gathered 200 patients divided into the two described groups. The mean age of Group A is 44 ± 8.49 and 43.73 ± 9.28. The mean preoperative BMI is 45.6 kg/m2 ± 6.71 for Group A and 48.9 ± 7.15 kg/m2 for Group B. Group A recorded a mean MAP of 83.06 ± 18.58 mmHg and group B a value of 111.88 ± 12.46 mmHg (p value < 0.05 and z-score is 4.15226 and the value of U is 13,900). We observed 9 cases of bleeding in group A, most of them being treated with medical therapy and transfusions; only 1 hemodynamically unstable patient underwent re-laparoscopy. We reported only 2 cases of bleeding in group B, one of which required blood transfusions. CONCLUSION: From our study we can conclude that increasing mean arterial pressure (MAP) by 30% compared to preoperative and reducing the pneumoperitoneum pressure of CO2 to 8 mmHg in the last 15 min of the operation led to a decrease in bleeding cases in group B and, most importantly, all the bleedings were easily controllable with medical therapy and/or transfusions. These measures allowed us to reduce postoperative bleeding.

Can indocyanine green during laparoscopic sleeve gastrectomy be considered a new intraoperative modality for leak testing?

BACKGROUND: Indocyanine green (ICG) when injected intravenously into the bloodstream allows us to show stomach vascularity in real time. The aim of our study was to observe the preliminary results of the application of indocyanine green fluorescence (IGF) during laparoscopic sleeve gastrectomy (LSG) in our center and how the perfusion of the staple line of the stomach affects the onset of fistula. MATERIALS AND METHODS: 82 patients underwent LSG with ICG fluorescence angiography at our center from January 2020 to December 2021. 5 ml of ICG was injected intravenously to identify the blood supply of the stomach, carefully assessing the angle of His. RESULTS: In the ICG-tested LSG, we recorded adequate perfusion in all patients but one: the leakage rate was 1.2%. This data is inferior to the non-tested patients' group. CONCLUSION: Intraoperative ICG testing may be helpful in determining which patients are at an increased risk for leakage but there are multiple factors contribute to the pathophysiology and the incidence of gastric fistula not only the perfusion. Trial registration Retrospectively registrated.

Emergency Surgery for Colon Diseases in Elderly Patients-Analysis of Complications, and Postoperative Course.

Background and Objectives: Colon diseases can turn in a clinical emergency with the onset of some important complications. Some critical conditions are more common in aged patients because they are frailer. The aim of this study is to examine patients over 80 years of age who are undergoing emergency colorectal surgery, and evaluating the aspects associated with post-operative complications and other problems in the short term. Methods: From November 2020 to February 2022, we included 32 consecutive patients older than 80 undergoing emergency surgery due to colon diseases. We collected and analysed all demographic and operative data, and then applied CR-POSSUM score and correlated this with postoperative hospital stay and the onset of postoperative complications according to the Clavien Dindo classification. Results: Postoperative factors were selectively evaluated based on the clinical scenario and different colic pathologies. There were no statistically significant differences, in terms of postoperative hospital stay, postoperative complications, reoperation rate and 30-day mortality. The number of cases of blood transfusions was significant and was more numerous in cases of intestinal perforation and bleeding cases. The value of the Operative Severity Score in bowel perforations was significantly higher. Conclusions: The use of a score to stratify the risk is a useful tool, especially in elderly patients undergoing emergency surgery. The CR-POSSUM score was important for predicting morbidity in our study. Emergency manifestations of colon diseases in the elderly show higher morbidity and mortality rates. The effect of age on outcome is a concept that needs to be emphasized, so further investigation is needed.

Tube Duodenostomy to Treat Large Duodenal Perforation: Our Experience and Literature Review.

Background: Duodenal perforation is a life-threatening condition and ideal approaches for the management of duodenal perforations are nowadays unclear, so numerous variables must be considered. Peptic ulcer disease is the most common disease determining a duodenal perforation, however, there may be other less common causes. Methods: We retrospectively analyzed all the patients who presented at our Division of General Surgery for a Duodenal Perforation, from September 2018 to December 2019. We focused on patients requiring a tube duodenostomy. Five patients were included in this study. Results: Five patients suffering from a duodenal perforation were analyzed and their data collected. All patients were treated with tube duodenostomy, pyloric exclusion and omega loop gastro-enteroanastomosis. The duodenostomy was removed four weeks after surgery. All patients suffered postsurgical complications ranging from wound infection to pneumonitis; the incidence of severe complications was greater in the older patients. We did not record any deaths four months after the operation. Conclusions: The tube duodenostomy is an old and dated procedure but simple to implement, which may require an increase in post-operative hospitalization, but which subsists as an effective and safe way to treat patients in critical conditions.

Is Emergency Surgery Back to Pre-Covid-19 Era? Our Cohort Study.

Introduction: The aim of this study is to analyze the progress of hospitalizations and how the emergency operations in our Department of Medical and Surgical Sciences of the Foggia Hospital have changed qualitatively and quantitatively from pre-Covid-19 to today. Methods: Our cohort-study was conducted by analyzing four groups of patients admitted in emergency to our department from 2019 to 2022. Results: We observed a total of 150 patients for the group 1, 25 patients for the group 2, 71 patients for the group 3 and 110 for the group 4, of these 20 were emergency admission during 2019, 16 during 2020, 31 during 2021 and 10 during 2020 (p 0.05); 130 were elective admission during 2019, 9 during 2020, 40 during 2021 and 100 during 2022 (p 0.05). Of the emergency admissions 11 were operated during the no covid period in 2019, 14 during 2020, 29 during 2021, 6 during 2022. Conclusions: The contraction of hospitalizations for urgent and emergency conditions during the first lockdown has been accompanied by positive implications. The measures employed in hospitals to contain the infection determined a reduction in COVID cases, allowing the nearly complete resumption of the surgical activity provided in the pre-COVID era.

Rating the incidence of iatrogenic vascular injuries in thoracic and lumbar spine surgery as regards the approach: A PRISMA-based literature review.

PURPOSE: To assess the rate, timing of diagnosis, and repairing strategies of vascular injuries in thoracic and lumbar spine surgery as their relationship to the approach. METHODS: PubMed, Medline, and Embase databases were utilized for a comprehensive literature search based on keywords and mesh terms to find articles reporting iatrogenic vascular injury during thoracic and lumbar spine surgery. English articles published in the last ten years were selected. The search was refined based on best match and relevance. RESULTS: Fifty-six articles were eligible, for a cumulative volume of 261 lesions. Vascular injuries occurred in 82% of instrumented procedures and in 59% during anterior approaches. The common iliac vein (CIV) was the most involved vessel, injured in 49% of anterior lumbar approaches. Common iliac artery, CIV, and aorta were affected in 40%, 28%, and 28% of posterior approaches, respectively. Segmental arteries were injured in 68% of lateral approaches. Direct vessel laceration occurred in 81% of cases and recognized intraoperatively in 39% of cases. CONCLUSIONS: Incidence of iatrogenic vascular injuries during thoracic and lumbar spine surgery is low but associated with an overall mortality rate up to 65%, of which less than 1% for anterior approaches and more than 50% for posterior ones. Anterior approaches for instrumented procedures are at risk of direct avulsion of CIV. Posterior instrumented fusions are at risk for injuries of iliac vessels and aorta. Lateral routes are frequently associated with lesions of segmental vessels. Suture repair and endovascular techniques are useful in the management of these severe complications.

Proteasome Inhibitors as a Possible Therapy for SARS-CoV-2.

The COVID-19 global pandemic is caused by SARS-CoV-2, and represents an urgent medical and social issue. Unfortunately, there is still not a single proven effective drug available, and therefore, current therapeutic guidelines recommend supportive care including oxygen administration and treatment with antibiotics. Recently, patients have been also treated with off-label therapies which comprise antiretrovirals, anti-inflammatory compounds, antiparasitic agents and plasma from convalescent patients, all with controversial results. The ubiquitin-proteasome system (UPS) is important for the maintenance of cellular homeostasis, and plays a pivotal role in viral replication processes. In this review, we discuss several aspects of the UPS and the effects of its inhibition with particular regard to the life cycle of the coronaviruses (CoVs). In fact, proteasome inhibition by various chemical compounds, such as MG132, epoxomycin and bortezomib, may reduce the virus entry into the eucariotic cell, the synthesis of RNA, and the subsequent protein expression necessary for CoVs. Importantly, since UPS inhibitors reduce the cytokine storm associated with various inflammatory conditions, it is reasonable to assume that they might be repurposed for SARS-CoV-2, thus providing an additional tool to counteract both virus replication as well as its most deleterious consequences triggered by abnormal immunological response.

Insulin-Like Growth Factor Binding Protein 6 Is Secreted in Extracellular Vesicles upon Hyperthermia and Oxidative Stress in Dendritic Cells But Not in Monocytes.

Recently, insulin-like growth factor binding protein 6 (IGFBP-6) has been shown to play a putative role in the immune system, as monocyte-derived dendritic cells (Mo-DCs) are stimulated by hyperthermia to express IGFBP-6 at both the mRNA and protein levels. However, the presence of IGFBP-6 in extracellular vesicles (EVs) and whether other pro-inflammatory stimuli can induce IGFBP-6 expression in Mo-DCs are not known yet. In this brief report, we show that hyperthermia (39 °C) induces IGFBP-6 secretion associated with microvesicles and exosomes as early as 3 h. Moreover, free IGFBP-6 is found in conditioned media (CM) of hyperthermia- and H2O2-treated Mo-DCs, but not in CM obtained from monocytes similarly treated. These results show that diverse inflammatory stimuli can induce IGFBP-6 association with EVs and secretion in conditioned medium, indicating a role for IGFBP-6 in communication between immune cells.

Energy Based Vessel Sealing Devices in Thyroid Surgery: A Systematic Review to Clarify the Relationship with Recurrent Laryngeal Nerve Injuries.

Background and objectives: The principal complications associated with thyroid surgery consist in postoperative recurrent laryngeal nerve (RLN) palsy, hypoparathyroidism, intra-operative and post-operative hemorrhage. In this paper, structured as a literature review, we describe the current knowledge and the technical improvements currently employed in the field of thyroid surgery, focusing on the contribution of energy based devices in relation with the reduction of the operating time and the odds of possible complication. Materials and methods: a relevant systematic literature search on Pubmed was carried out including works from 2004 through 2019, selecting studies providing information on the energy based devices employed in surgeries and statistic data concerning RNL (transient and permanent) injury and operative time. Results: Nineteen studies were reviewed, dealing with 4468 patients in total. The operative variables considered in this study are: employed device, number of patients, pathological conditions affecting the patients, surgical treatment, RNL injury percentage and the operating time, offering an insight on different patient conditions and their relative operative outcomes. A total of 1843 patients, accounting to the 41.2% of the total pool, underwent the traditional technique operation, while 2605 patients (58.3%) were treated employing the energy based devices techniques. Thyroidectomy performed by approaches different from traditional (for example robotic, MIVAT (Mini Invasive Video Assisted thyroidectomy)) were excluded from this study. Conclusions: The energy-based vessel sealing devices in study, represent a safe and efficient alternative to the traditional clamp-and-tie hand technique in the thyroidal surgery scenario, granting a reduction in operating time while not increasing RNL injury rates. According to this information, a preference for energy based devices techniques might be expressed, furthermore, a progressively higher usage rate for these devices is expected in the near future.

Bladder Metastases from Breast Cancer: Managing the Unexpected. A Systematic Review.

Breast cancer (BrC) has the highest incidence among females world over and it is one of the most common causes of death from cancer overall. Its high mortality is mostly due to its propensity to rapidly spread to other organs through lymphatic and blood vessels in spite of proper treatment. Bladder metastases from BrC are rare, with 50 cases having been reported in the last 60 years. This review aims to discuss some critical points regarding this uncommon condition. First, we performed a systematic review of the literature in order to draw a clinical and pathological profile of this entity. On this basis, its features in terms of diagnostic issues, imaging techniques, and survival are critically examined. Most bladder metastases from BrC are secondary lobular carcinoma, which mimic very closely the rare variant of urothelial cancer with lobular carcinoma-like features (uniform cells with an uncohesive single-cell, diffusely invasive growth pattern); thus, immunohistochemistry is mandatory to arrive at a correct diagnosis. This article summarizes the current knowledge regarding the incidence, clinical presentation, diagnosis, prognosis, and treatment of bladder metastases in patients with BrC.

Spleen assessment after laparoscopic transperitoneal left adrenalectomy: preliminary results.

BACKGROUND: Several laparoscopic approaches to the adrenal gland have been described. We prefer the lateral transabdominal approach. The aim of this study is to evaluate prospectively the presence of any anatomical and dynamic changes in the spleen after laparoscopic transperitoneal left adrenalectomy (LTLA), which can cause an increased risk of early and late complications. METHODS: We have evaluated 21 patients before and 6 months after surgery in order to verify the possible presence of a wandering spleen. A clinical and instrumental follow-up [ultrasound (US), magnetic resonance (MR)] were performed. During US protocol, in supine, right lateral, and orthostatic position, the longitudinal and anteroposterior diameter of the spleen and the resistive index within 3 cm of the origin of the splenic artery in three different measurements averaged were measured. MR protocol evaluated, in supine and right lateral position, the splenic volume and its distances from the diaphragm dome and the lateral margin of the costal arch. RESULTS: p Values calculated for each parameter were not statistically significant. Our results confirm the absence of any anatomical and dynamic changes in the spleen after LTLA. CONCLUSIONS: The most common complications after laparoscopic adrenalectomy are well known and widely described. Our experience does not exclude the occurrence of a wandering spleen, but allows us to state that a rightful mobilization of the pancreaticosplenic block can avoid this event, and in agreement with other authors, the presence of a wandering spleen remains an isolated complication.

A recurrent epidermoid cyst of the spleen: report of a case and literature review.

BACKGROUND: Splenic cysts are rare disease. Epidermoid cysts of the spleen belong to the primary nonparasitic splenic cysts group. They are an unusual event in surgical practice. Usually, epidermoid cysts occur in children and young female. Most often, they are asymptomatic, but they may present with abdominal discomfort. CASE PRESENTATION: We are reporting a rare case of a 23-year-old female came to our attention with history of intermittent pain and previously undergone two times to laparoscopic decapsulation of the cyst in others institutions. During hospitalization, serum and intracystic levels of tumor marker CA19-9 increased. Enhanced CT of the abdomen showed recurrent large cyst in the upper pole of the spleen with satellite nodules. Laparotomic total splenectomy was performed. Histopathological and immunoreactive examinations were executed, and they revealed stratified squamous epithelium on the inner surface of cystic wall, which was positive for EMA, CEA, and CA19-9. The diagnosis of epidermoid cyst was confirmed. CONCLUSIONS: Recently, the surgical approach is changing towards conservative treatments in order to save the spleen in young patients for immunological reasons. Sometimes, this target is not achievable. In such circumstances, like recurrent large cyst, anomalous anatomical relationship to the surrounding tissues, total splenectomy is safe and necessary.

Can robotic gastric bypass be considered a valid alternative to laparoscopy? Our early experience and literature review.

Background: Robotic bariatric surgery serves as an alternative to laparoscopy. The technology provides the surgeon with an accurate three-dimensional view, allowing complex maneuvers while maintaining full control of the operating room. Hypothesis: We report our experience with this innovative surgery compared with laparoscopy during Roux-en-Y gastric bypass to demonstrate its safety and feasibility. The aim of this study is to evaluate potential differences between the robotic and laparoscopic techniques. Materials and methods: Our study retrospectively identified 153 consecutive obese patients who underwent either laparoscopic or robotic gastric bypass (RGB) procedures over a 2-year period at the Department of Medical and Surgical Sciences, University of Foggia. Data on demographics, operative time, conversion rate, length of hospital stay, and mortality were collected and compared between two groups of patients: 82 patients who underwent laparoscopic procedures and 71 who underwent robotic procedures. Results: We analyzed 153 patients who underwent gastric bypass with a mean age of 42.58 years, of whom 74 were female; 71 were treated with a robotic approach and 82 with a laparoscopic approach. The mean operative time was 224.75 ± 10.4 min for RGB (including docking time) and 101.22 min for laparoscopic gastric bypass (LGB) (p < 0.05), which is statistically significant. The median length of stay was 4.1 days for the RGB group and 3.9 days for the LGB group (p = 0.89). There is only one conversion to laparoscopy in the RGB group. We observed only one case of postoperative complications, specifically one episode of endoluminal bleeding in the laparoscopic group, which was successfully managed with medical treatment. No mortality was observed in either group. Conclusion: The statistical analysis shows to support the robotic approach that had a lower incidence of complications but a longer operative duration. Based on our experience, the laparoscopic approach remains a technique with more haptic feedback than the robotic approach, making surgeons feel more confident.This study has been registered on ClinicalTrial.gov Protocol Registration and Results System with this ID: NCT05746936 for the Organization UFoggia (https://clinicaltrials.gov/ct2/show/NCT05746936).

Banded versus non-banded Roux-en-Y gastric bypass: short, mid, and long-term surgical outcomes - a systematic review and meta-analysis.

BACKGROUND: The Roux-en-Y gastric bypass (RYGB) is considered as one of the most effective treatments for people with obesity. A variant of this procedure, the banded-RYGB, may present several advantages over the standard technique. These potential benefits include enhanced weight loss, decreased recurrent weight gain, a lower incidence of dumping syndrome, and less distention of the jejunum below the gastrojejunostomy. OBJECTIVES: The objective of this meta-analysis is to compare the surgical outcomes of RYGB procedures with a band (banded-RYGB) and without a band (RYGB) in the management of individuals with obesity. SETTING: A systematic review and meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Cochrane protocol (PROSPERO ID: CRD42023439874). METHOD: The systematic review process led to the identification of 13 comparative studies involving 3230 patients who underwent banded-RYGB and 5302 who received RYGB, all of which were eligible for inclusion and meta-analysis. RESULTS: Four studies reported data on 1-year postoperative percent excess weight loss (%EWL), demonstrating a significant increase of 6.03 %EWL in patients who underwent banded-RYGB. Four studies reported the 2-year postoperative %EWL, showing that patients who had banded-RYGB experienced a 5.32 greater %EWL compared to those who received RYGB, even if this was not statistically significant. For 5-year %EWL after bariatric surgery, 5 studies were included for continuous outcome meta-analysis. The average 5-years %EWL difference was 7.6 in favor of banded-RYGB. Patients who had banded-RYGB presented a nonsignificant 1.45 OR of developing postoperative complications compared to patients receiving RYGB. CONCLUSION: This meta-analysis demonstrates that, compared to RYGB, patients who underwent banded-RYGB surgery showed a statistically significant increase in the %EWL at 1, 2, and 5 years postoperatively. Moreover, the banding procedure does not significantly increase the risk of postoperative complications.

Metastatic melanoma causing small bowel perforation: A case report.

INTRODUCTION AND IMPORTANCE: Metastatic localization of melanoma often affects the gastrointestinal tract, with reference to the small intestine. CASE PRESENTATION: In this work we present the clinical course of a patient affected by a surgically treated melanoma of the right conjunctiva, suddenly manifesting abdominal symptomatology. The abdominal computed tomography scan (CT scan) show evidence of free air into the peritoneal cavity, cholecystitis and brain lesions highly suspicious for metastases. Patient underwent emergency surgery, consisting of ileo-cecal resection, cholecystectomy, with the construction of an ileostomy. The histological examination diagnosed multiple ileal and gallbladder localizations of pigmented epithelial melanoma, and localization. CLINICAL DISCUSSION: The treatment of conjunctival melanoma consists in surgical removal. Distant metastases frequently affect the gastrointestinal tract, leading to the necessity to assess patients with abdominal symptoms, in order to avoid emergency scenarios such as the one reported in our study. CONCLUSIONS: Intra-abdominal metastases from melanoma are an event that should not be underestimated, because if detected in time, they can be treated with surgery resulting in a clear improvement in the prognosis. Late diagnosis of intestinal metastases can cause an acute abdomen scenario frequently caused by intestinal obstruction or gastrointestinal bleeding.

Efficacy of Cal-Cemex as bone substitute for tibial plateau fractures.

BACKGROUND: Various factors influence treatment and outcomes in tibial plateau fractures. Bone defects are among them. Many materials have been proposed to address this problem: allograft, bone-cements and various bone substitutes (BSM). Cal-Cemex (ß-tricalciophosphate and polymethylmethacrylate) is a new hybrid bi-component BSM. A retrospective multicenter study was conducted based on the clinical experience of three European Hospitals, to demonstrate its clinical effectiveness, versatility and safety. MATERIALS AND METHODS: From December 2016 to March 2022, 45 displaced tibial plateau fractures were treated with internal fixation and augmentation using Cal-Cemex. The average age was 55.9 years. According to Schatzker classification, we included 13 type II, 24 type III, 3 type V and 4 type VI fractures. The postoperative follow-up (FU) consisted of clinical and radiological examinations at 6 and 12 weeks and 1 year after surgery. A CT scan was performed preoperatively and 1 year after surgery. Full weight bearing was permitted after less than 6 weeks. Clinical data were collected from patient charts, while functional data were evaluated using the Rasmussen knee function score, the KOOS score and the Hospital for Special Surgery knee rating score (HSS), to evaluate the range of motion, axis and functionality of the knee. RESULTS: The average FU was 42.8 months. CT scans taken at 1 year demonstrated a good surface osteointegration without radiolucent lines or osteolysis with good evidence of interdigitation and even bone ingrowth. At 1-year FU, the mean Rasmussen score was 24.7, the mean KOOS score was 90.7 and the mean HSS was 89.9 and the average full weight-bearing period 34.9. No patients had hardware failure or fracture secondary displacement. DISCUSSION: Cal-Cemex combines biological features and good mechanical performances. It guarantees biocompatibility and osteoconductivity, although it is not fully reabsorbable; ß-tricalciophosphate component gives macro- and microporosity that allow fluids to penetrate inside the material, to stimulate bone ingrowth. CONCLUSIONS: The study suggests that Cal-Cemex is an option for tibial plateau fractures, where augmentation and support are necessary for early full weight bearing. The absence of major complications, ease of application, the possibility to cut and perforate this material support its extensive use in bone augmentation for trauma cases.

The new onset of GERD after sleeve gastrectomy: A systematic review.

Background: The main adverse effect is gastroesophageal reflux disease (GERD), with concern on the development of Barrett's esophagus and esophageal adenocarcinoma in the long term. However, the relationship between SG and GERD is complex. The aim of this study is to systematically evaluate all published data existing in the literature to evaluate the effect of sleeve gastrectomy on GERD, esophagitis, BE in order to clarify the long-term clinical sequelae of this procedure. Materials and methods: This systematic review was conducted in accordance with the guidelines for Preferred Reporting Items for Systematic Review. The work has been reported in line with the PRISMA criteria [19]. We evaluated the quality and risk of bias of this Systematic Review using AMSTAR 2 checklist [20]. Published studies that contained outcome data for primary sleeve gastrectomy associated with the primary and secondary outcomes listed below were included. The UIN for ClinicalTrial.gov Protocol Registration and Results System is: NCT05178446 for the Organization UFoggia. Results: 49 articles were eligible for inclusion that met the following criteria: publications dealing with patients undergoing laparoscopic SG, publications describing pre- and postoperative GERD symptoms and/or esophageal function tests, articles in English, human studies and text complete available. Conclusions: We have controversial data on LSG and GERD in the literature as there is a multifactorial relationship between LSG and GERD. The most recent studies have shown satisfactory control of postoperative reflux in most patients and low rates of de novo GERD. These data are leading to wider acceptance of LSG as a bariatric procedure even in obese patients with GERD.

Leak after sleeve gastrectomy with positive intraoperative indocyanine green test: Avoidable scenario?

BACKGROUND: The staple line gastric leak (GL) is estimated to be the most serious complication of the sleeve gastrectomy. The use of indocyanine green (ICG) has been introduced in minimally invasive surgery to show the vascularization of the stomach in real time and its application to the gastroesophageal junction (GE) during Laparoscopic Sleeve Gastrectomy (LSG) seems very promising. CASE PRESENTATION: We present the case of a 40-year-old female underwent laparoscopic sleeve gastrectomy. Intraoperative indocyanine green test showed a small dark area in the proximal third of the staple line reinforced with fibrin glue. Two weeks later the patient presented to the emergency room (ED) with abdominal pain, fever, vomiting, intolerance to oral intake and the evidence of a leak on the abdomen Computer Tomography (CT). The UIN for ClinicalTrial.gov Protocol Registration and Results System is: NCT05337644 for the Organization UFoggia. CONCLUSIONS: This case report shows that intraoperative ICG test can be helpful in determining which patients are at greater risk of the leak and, more importantly, the cause of the leak but further tests are needed to determine if the ICG predicts leak due to ischemia.

Banded versus non-banded sleeve gastrectomy in obese patients: A systematic review & meta-analysis.

BACKGROUND & AIMS: Weight regain represents an important issue after sleeve gastrectomy (SG), hence banded sleeve gastrectomy (BSG) was proposed. Aim of this meta-analysis was to compare the performance ofBSG versus SG in obese patients. METHODS: We searched the PubMed/Medline and Embase database through October 2020 and identified 6 studies, of which 2 randomized-controlled trials (recruiting673 patients). The primary outcome was % excess weight loss (%EWL); secondary outcomes included % total weight loss (%TWL), HbA1c improvement, overall complication and major complication rate, gastro-esophageal reflux disease (GERD)occurrence. We performed pairwise meta-analysis through a random effects model and expressed data as standardized mean difference (SMD) or odds ratio (OR) and 95% confidence interval (CI). RESULTS: A sharp decline in %EWL at 1 year was observed with both treatments with no significant difference (SMD 5.99, -1.17 to 13.16), whereas a clear benefit with BSG over SG was observed over time (SMD 15.95, 13.31 to 18.58 at 2 years; 18.37, 13.31 to 23.42 at 3 years; 24.75, 22.38 to 27.12 at 4 years; 29.85, 27.22 to 32.49 at 5 years). Meta-regression did not find any significant correlations between age, sex, and baseline BMI with %EWL. Similarly, no difference in terms of %TWL was observed at 1 year (SMD 1, -3.31 to 5.30), whereas the magnitude of the benefit with BSG increased significantly from the second year onwards (SMD 5.99, 3.7 to 8.27 at 2 year, 6.86, 5.13 to 8.59 at 3 year, and 9.36, 7.07 to 11.65 at 5 year). No difference in terms of HbA1c improvement was observed (SMD 0.40, -0.64 to 1.43). No difference in overall complication (OR 1.44, 0.55-3.76), major complications (OR 1.14, 0.52-1.87), and incidence of GERD was observed (OR 1.06, 0.56-2). CONCLUSION: BSG is superior to SG in obese patients, due to its ability to significantly increase %EWL with no additional safety issues.
