RESUMO
INTRODUCTION: achalasia is a chronic disease. Since there is no curative treatment, diagnosed patients have pharmacological and/or surgical techniques available, aimed at minimizing the condition. POEM appears as a promising new type of palliative treatment with good rates of symptom improvement. OBJECTIVE: evaluate the profile of POEM at the Clinical Hospital of the Federal University of Pernambuco (HC - UFPE) and correlate it with the world scenario. METHODS: data collection was performed retrospectively from September 2017 to October 2019 with all patients undergoing POEM at the HC - UFPE. Sociodemographic, clinical, and hospital variables were evaluated before and three months after the procedure. RESULTS: of 27 patients (52.41 ± 19.24 years old) who underwent the procedure, 66.7% had idiopathic etiology and 33.3% had etiology secondary to Chagas disease. 48% patients underwent previous procedures, of which seven used some type of medication for symptom control, two underwent pneumatic endoscopic dilation, and four underwent Heller cardiomyotomy with partial fundoplication. 62.5% of the evaluated patients had type II achalasia before the procedure. Seven (25.9%) patients presented the following adverse events: four presented bleeding, two pneumoperitoneum, and one both complications, all being treated conservatively. The Eckardt score reduced from 8.37 ± 1.45 to 0.85 ± 1.06 (p-value <0.001). CONCLUSION: clinical improvement of symptoms and the patient profile followed the worldwide trend, with emphasis on the etiology secondary to Chagas disease, endemic in Brazil. Gastroesophageal reflux remains the main post-operative symptom.

PURPOSE: The purpose of this study is to determine the incidence of gastric tube abnormalities after SG and its relationship with esophagitis progression. METHODS: Retrospective study which included 459 patients in the postoperative period of SG who underwent an esophagogastroduodenoscopy in both pre- and postoperative periods. The main studied variables were presence of gastric tube abnormalities (dilation, neofundus, twist, and hiatal hernia) and esophagitis progression. RESULTS: Among the 459 patients who underwent SG, 393 (85.6%) were women, and 66 (14.4%) men, with mean age of 40.4 years. Mean preoperative BMI was 39.70 kg/m2. In total, 20.3% of the sample presented progression of esophagitis after surgery. Among the whole sample, 130 (28.3%) presented with an abnormality of the remnant gastric tube. The most common alteration was gastric dilation, which occurred in 16.1% of the patients, followed by gastric twist (10.7%), neofundus (7.4%), and hiatal hernia (0.2%). Patients who presented with any abnormality of the gastric tube were significantly prone to presenting esophagitis progression (p = 0.013). When analyzing each morphological abnormality isolated, there was no statistically significant correlation. CONCLUSION: Abnormalities of the gastric tube are not uncommon after SG and seems to contribute partially to the relevant rates of GERD and esophagitis after this surgery.

INTRODUCTION: to evaluate the long-term impact of bariatric surgery in the elderly population. METHODS: a retrospective study including all patients older than 60 years who underwent Roux-en-Y gastric bypass (RYGB) at our center and maintained a follow-up longer than 1 year. Clinical and laboratory variables were studied to assess remission of obesity and its comorbidities, as well as variables directly related to the surgical procedure itself, including early and late complications. RESULTS: fifty-six patients were studied, mostly female (76,8%), with a mean age of 64.02 ± 3.34. A rate of complications of 37,5% was observed, with 10,7% requiring hospital admission and emergency surgery. The mean excess weight loss (%EWL) was 74.22% ± 26.76. The remission rates of hypertension and diabetes mellitus were 26.08% and 54.54%, respectively. There was significant difference in BMI reduction (12.25 ± 5.42, p<0.001), total cholesterol (31.37 ± 38.89 p<0,001), LDL cholesterol (23.45 ± 34.9, p=0.002), HDL cholesterol (5.14 ± 11.13, p=0,024), triglycerides (48.85 ± 56.15 p<0.001), HbA1C (1,81 ± 1,97, p<0,001) e PCR (1.43 ± 1.96, p<0.001). CONCLUSION: bariatric surgery was effective in weight loss and remission of comorbidities in the elderly obese population within the long term.

OBJECTIVE: The twisting of the gastric tube is one of the main causes of persistent reflux and food intolerance after sleeve gastrectomy (SG). To date, there is no classification for gastric twist after SG. This study aimed to propose an endoscopic classification for this condition and outline the clinical profile of these patients with sleeve gastrectomy. METHODS: Patients in the postoperative period of SG presenting endoscopic findings of gastric twist were included. All patients underwent an esophagogastroduodenoscopy 12 months after SG. The classification proposed consists of three degrees: degree I: mild rotation of the staple line without relevant shrinkage of the gastric lumen; degree II: moderate rotation of the staple line, leading to a focal area of fixed narrowing that requires additional maneuvers for its transposition; and degree III: severe rotation of the staple line leading to stenosis, with increased difficulty for transposition or complete blockage. RESULTS: Out of 2,723 patients who underwent SG, 45 (1.6%) presented gastric twist. Most patients were female (85%), with mean age of 39±10.4 years. In all, 41 (91.1%) presented degree I, 3 (6.7%) presented degree II, and 1 (2.2%) had degree III. Most patients were asymptomatic (n=26). Vomiting was the most prevalent symptom (15.5%). Statistically significant correlation of twisting degrees was not observed for both the presence of symptoms and the degrees of esophagitis. CONCLUSION: Gastric twist after SG is rare, with generally mild and asymptomatic presentation. The endoscopic classification was not statistically related to clinical presentation but set the ground for further analysis.

BACKGROUND: Recent experimental studies have suggested a potential link between cathepsin S (CTTS) and gastric adenocarcinoma progression. Herein, we aimed to evaluate the expression of CTTS in gastric adenocarcinoma in patients who underwent curative-intent surgical resection. METHODS: This was a cross-sectional study that included two groups: gastric adenocarcinoma (n = 42) and gastritis (n = 50). The gastritis group was then subdivided into H. pylori-positive (n = 25) and H. pylori-negative (n = 25) groups. Gastric tissue samples were analysed to determine CTTS expression through immunohistochemistry. Samples were obtained by oesophagogastroduodenoscopy or surgical specimens. RESULTS: In patients with gastritis, the age ranged from 18 to 78 years. Among them, 34% were male, and 66% were female. In patients with gastric adenocarcinoma, the age ranged from 37 to 85 years. Among them, 50% were male. When comparing the expression of CTTS between the two groups, only 16% of the gastritis samples had an expression higher than 25%. Alternatively, among patients with gastric adenocarcinoma, 19% had expression between 25-50%, 14.3% between 51-75%, and 26.2% had expression higher than 75% (p < 0.001). In the gastritis group, CTTS expression was significantly higher in patients with a positive test for H. pylori than negative test for H. pylori: 87.5% and 38.5%, respectively (p<0.001). There was no statistically significant association between CTTS positivity and clinicopathological variables, including tumour staging, histological type, angiolymphatic invasion, recurrence, current status and death. CONCLUSION: CTTS expression is higher in gastric adenocarcinoma samples. Patients with gastritis due to H. pylori also show a higher expression of CTTS than patients with negative results for this bacterium.

BACKGROUND: Although there is a rationale supporting that preoperative showering with 2% or 4% chlorhexidine gluconate (CHG) would decrease skin bacterial colonization, there is no consensus that this practice reduces the risk of surgical site infection (SSI). OBJECTIVES: Analyze the skin concentration of CHG after preoperative showering associated with the traditional skin preparation with CHG 4% for breast surgery. METHODS: Randomized controlled trial that included 45 patients, all candidates for augmentation mammaplasty, allocated into three groups (A: no preoperative showering; B: one preoperative showering; C: two preoperative showering with CHG 4%) in a 1:1:1 ratio. Skin swabs collection was performed right before the surgical incision. The samples were, then, sent to spectrophotometry in order to determine the skin concentration of CHG at the beginning of surgery. RESULTS: The age ranged from 18 to 61 years, with a mean of 37 years old. Group C had the lowest median concentration (0.057) followed by group B (0.060) and group A (0.072), however, with no statistical significance. The areola was the place with the lowest median concentration level (0.045), followed by the axilla (0.061) and the inframammary fold (IMF) (0.069). Still, when comparing the distribution of the sites, a statistically significant difference was found only between the axilla and the areola (p = 0.022). CONCLUSION: Preoperative showering with CHG 4% did not increase the concentration of this agent on the skin surface right before the surgical incision.

PURPOSE: to outline the clinical and laboratorial profile of patients with obesity undergoing bariatric surgery who presented positive reverse transcription-polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus-2 (Sars-CoV-2) in the preoperative period without symptoms presentation. METHODS: Case series of 17 patients undergoing bariatric surgery who presented positive RT-PCR for Sars-CoV-2 in the preoperative period, with no reported symptoms. Data collected included demographic characteristics, length of hospital stay, waiting time for surgery, inflammatory markers, serum levels of micronutrients and dengue virus (DENV) serology. RESULTS: In total, 219 patients underwent bariatric surgery in our institution during the study period. The incidence of asymptomatic cases was 7.7%. The sample comprised 88.2% of women, with mean age of 39.3 years and mean preoperative body mass index (BMI) of 37.7 kg/m2. Thirty five percent of the sample had previous diagnosis of diabetes and 29.4% had hypertension. The mean time elapsed between positive RT-PCR and the operation was 17 ± 7.5 days and the mean length of postoperative hospital stay was 1.9 ± 0.43 day. Mean lymphocytes count was 2,409.7/mm3 and the mean platelet-to-lymphocyte ratio was 126.3. Mean C-reactive protein value was 5.8 mg/dL, while ferritin marked 107.4 µg/L. DENV IgG was identified in all patients who tested for it. Mean levels of vitamin D and zinc were 25.6 ng/mL and 79.9 µg/dL, respectively. There were no postoperative complications reported. CONCLUSION: None of the included patients presented any of the laboratory markers related to disease severity. Moreover, it is important to notice that all patients who tested for DENV, had the specific IgG detected in their serum.

BACKGROUND: Gastro-omentopexy promotes the reconnection of the stomach to the gastroesplenic and gastrocolic ligaments and constitutes an alternative for the prevention of complications in laparoscopic vertical gastrectomy. AIM: To demonstrate the benefits of the gastro-omentopexy technique in patients undergoing sleeve gastrectomy, with possible reduction in postoperative complications. METHODS: Prospective, non-randomized, case series type study, consisting of a clinical population of 179 patients who underwent the technique in 2018, with follow-up between 6-12 months in the postoperative period. RESULTS: From the participants 71.5% were women, aged between 30-40 years (36.3%). As for the prevalence of complications in the postoperative period, the low prevalence was evident, with emphasis on readmission (1.1%); reoperation (1.1%); wound infection (1.1%); bleeding hemorrhage (0.5%); and stricture (1.1%). However, temporary symptoms were present such as nausea/vomiting, food intolerance, epigastric pain and feeling of fullness, right after surgery. CONCLUSION: The technique promoted a significant improvement in quality of life and control of comorbidities. In addition, it was associated with a low prevalence of stenosis, and with no fistula, making the method safer.

BACKGROUND: Although considered a safe procedure, sleeve gastrectomy (SG) has a non-negligible risk of major postoperative complications related to it, with special attention to gastric leaks. AIM: Evaluate the clinical value of the methylene blue test (MBT) in predicting the occurrence of post-SG leaks. METHODS: Retrospective study that included 1136 patients who underwent SG with intraoperative MBT between 2012 and 2016. Sensitivity, specificity, positive predictive value (PPV) and negative predicted value (NPV) were calculated to determine the clinical correlation between the MBT and the occurrence of postoperative leaks. Staple line oversewing was performed in all patients who presented positive MBT. RESULTS: Laparoscopic SG was performed in 97.0% of cases; open in 2.3%, and robotic in 0.7%. MBT was positive in 19 cases (1.67%). One positive MBT occurred during an open SG and the other 18 at laparoscopy. Moreover, there were nine cases (0.8%) of postoperative leaks, among which, only two presented positive MBT. MBT diagnostic value was evaluated through the calculation of sensitivity (22.0%), specificity (98.0%), PPV (11.0%) and NPV (99.0%). There were no cases of allergic reaction or any other side effect with the use of the methylene blue solution. CONCLUSION: MBT showed high specificity and negative predictive value, thus presenting an important value to rule out the occurrence of postoperative leaks.

PURPOSE: The aim of this study was to determine the real influence of bariatric surgery on the clinical evolution of patients infected with SARS-Cov-2 in the postoperative period. METHODS: We conducted a retrospective analysis including two groups of patients: those who presented COVID-19 before bariatric surgery and those who presented it within 3 months of postoperative. Primary outcome was related to the severity of COVID-19, measured by the following variables: presence of symptoms, need for hospitalization, ICU admission, and invasive ventilation. Laboratory markers for inflammatory response, glycemic status, and micronutrients were analyzed as secondary outcomes. RESULTS: From the 222 individuals operated on within the study period, only 66 (29.7%) presented COVID-19, 42 (18.9%) in the preoperative period and 24 (10.8%) after the procedure. Mean age was 36.3 ± 9.5 years and mean preoperative BMI was 39.9 ± 4.2 kg/m2. There were no statistically significant differences between the groups regarding symptoms presentation (92.9% × 87.5%, p = 0.66), need for hospitalization (11.9% × 16.7%, p = 0.713), ICU admission (4.8% × 4.2%, p = 1.000), and invasive ventilation (2.4% × 0.0%, p = 1.000). Regarding the quantitative variables, absolute lymphocyte count was significantly lower in the group who presented COVID-19 after surgery (1822.9 ± 482.2 × 2158.6 ± 552.9, p = 0.035). CONCLUSION: Patients who had COVID-19 before and after sleeve gastrectomy did not differ with statistical significance for the presence of symptoms, need for hospitalization, ICU admission, and invasive ventilation.
