TITANIUM CLIPS FOR CLOSURE OF THE PERITONEAL FLAP DURING LAPAROSCOPIC INGUINAL HERNIA REPAIR.

BACKGROUND: The laparoscopic approach for inguinal hernia repair has been widely used since its introduction in the 1990s. As a step in the procedure, the surgeon must access the preperitoneal space through an incision in the peritoneum, creating an adequate dissection for mesh placement. At the end of the procedure, the peritoneal flap must be closed to avoid adhesions. There are several methods to close the peritoneum. AIMS: The aim of this study was to propose a simple method for closing the peritoneal flap, using titanium clips, exposing its advantages and disadvantages. METHODS: Description of the peritoneum flap closure technique, using titanium clips, in the last 15 years. RESULTS: The pneumoperitoneum was reduced to a pressure of 7 mmHg; then, the two edges of the peritoneal flap were approximated together and, with the aid of a Maryland grasper, were kept together; titanium clips were used to close the flap. The process is repeated along the entire peritoneal incision until it is completely closed. CONCLUSIONS: The use of titanium clips proved to be a fast, inexpensive, and effective method for closing the peritoneal flap in videolaparoscopic inguinal hernioplasties, with no major or recurrent complications reported. Therefore, it is an effective and safe method for the closure of the peritoneal defect.

Wandering spleen as a cause of sinistral portal hypertension

Wandering spleen (WS) is a rare entity characterized by laxity of peritoneal ligaments that hold the spleen stationary. It is most commonly diagnosed in children and young women. Clinical presentation ranges from asymptomatic to acute abdomen. A 19-year-old woman came to the emergency department with history of progressive abdominal pain. She also had previous episodes of hematemesis. A computed tomography scan showed an ectopic spleen with a "whirlpool sign." Laparotomy and splenectomy were performed. WS is characterized by a long vascular pedicle and laxity of peritoneal attachments of the spleen. The etiology is usually congenital. Splenopexy is the main treatment; however, splenectomy is indicated when splenic infarction is present. Despite being rare, this condition may be considered in some cases of abdominal pain. An earlier diagnosis would have allowed us to perform a splenopexy, thus reducing morbidity. (AU)

Gastrointestinal emergency care during the COVID-19 pandemic: rapid communication.

OBJECTIVE: Social distancing during the COVID-19 pandemic has been associated with a decrease in the search for medical care. High-risk patients have avoided hospital environments fearing infection. We hypothesize that there was also a decrease in the search for medical care related to gastrointestinal emergencies. The aim of this study is to evaluate the frequency of consultations for severe gastrointestinal emergencies during and before the months of the pandemic. METHODS: This was a transversal study. The inclusion criteria were cases of consultation in the emergency department for gastrointestinal diseases that required hospitalization, from January to April, from 2015 to 2020. The pediatric population (under age 12) was excluded. RESULTS: A total of 2,457 cases of cases was included. The number of emergency hospitalizations for gastrointestinal cases decreased during the first four months of 2020: 108, 112, 82, and 77, respectively. Comparing April of 2020 with previous years, there was a lower than expected number of cases during the social distancing period (P=0.002). CONCLUSION: This study reports a pronounced decrease in consultations for severe gastrointestinal emergencies during the pandemic. Governments and society should be aware that health crises do not halt the natural occurrence of noninfectious diseases; otherwise, an increase in mortality from these morbidities may arise.

Preoperative Level of Leptin Can Be a Predictor of Glycemic Control for Patients with Diabetes Undergoing Bariatric Surgery.

INTRODUCTION: Bariatric surgery is a first-line treatment for patients with obesity and diabetes. It is uncertain whether leptin has an influence on glycemia in the postoperative period. METHODS: A cohort study of thirty-eight individuals with obesity and diabetes who underwent laparoscopic Roux-en-Y gastric bypass was undertaken. The levels of leptin, glucose, and glycosylated hemoglobin were verified in the preoperative period and in the first and third postoperative months. RESULTS: The majority of patients were women (81.6%), and the mean age was 47.3 years (SD 8.8). The mean BMI was reduced by 17.75% (from 47.3 to 38.9 kg/m2) and the mean glycemia by 26.76%. Preoperative leptin had a moderate positive correlation with glucose level at the third month (Pearson r = 0.46, P = 0.02), but not with HbA1c. Patients with leptin above 27.34 ng/mL had a higher glucose level at the end of observation (101.9 versus 88.9, t test, P = 0.042). CONCLUSION: The search for factors that influence diabetes control after bariatric surgery is of major importance in clinical practice. Our study reported a level of leptin that can predict the prognosis of glycemic control after the intervention. This finding still needs to be validated and confirmed in other populations.

RESUMO OBJETIVO: O distanciamento social durante a pandemia por COVID-19 tem sido associado a uma redução na busca por atendimento médico. Pacientes de alto risco têm evitado ambiente hospitalar com receio de infectar-se. Nossa hipótese é de que houve também uma redução no atendimento médico a emergências gastrointestinais. O objetivo deste estudo é avaliar a frequência de consultas por emergências gastrointestinais graves durante e antes da pandemia. MÉTODOS: Estudo transversal. O critério de inclusão foram casos de consulta em emergência por patologia gastrointestinal que tenham requerido hospitalização, de janeiro a abril dos anos 2015 a 2020. A população pediátrica foi excluída. RESULTADOS: Um total de 2.457 casos foi incluído. O número de hospitalizações via emergência durante os primeiros quatro meses de 2020 foi: 108, 112, 82 e 77, respectivamente. Comparando abril de 2020 com anos anteriores, houve um número de atendimentos abaixo do esperado (p=0,002). CONCLUSÃO: Este estudo relata uma redução pronunciada em atendimentos por emergências gastrointestinais graves na pandemia. Governos e sociedade devem estar cientes de que tais crises de saúde não interrompem a ocorrência natural de doenças não infecciosas, do contrário poderá ocorrer um aumento na mortalidade por outras morbidades.

Elastic Fibers Density: a New Parameter of Improvement of NAFLD in Bariatric Surgery Patients.

PURPOSE: Obesity is a major risk factor for nonalcoholic fatty liver disease (NAFLD), affecting 25% of the worldwide population. Weight loss through bariatric surgery can improve much of the liver steatosis, inflammation, and fibrosis. However, it is not known whether there is reversal of the elastic fiber deposition process, triggered by hepatic damage and related to worse prognosis. MATERIALS AND METHODS: Individuals submitted to bariatric surgery at our institution, from March 2016 to June 2017, with intraoperative liver biopsy confirming NAFLD were approached. Those who consented were submitted to a second liver biopsy 1 year later and were included. Specimens were sliced and stained with hematoxylin-eosin and Sirius red for histological assessment according to Brunt's criteria and with orcein for digital analysis morphometrics using ImageJ®. Quantification of elastic fibers was accomplished by corrected integrated density. RESULTS: Thirty-seven patients were included. Body mass index, metabolic markers, NAFLD activity score, and fibrosis improved 1 year after the procedure. The elastic fiber density showed a significant decrease: 239.3 × 103 absorbance micrometer2 (141.08-645.32) to 74.62 × 103 absorbance micrometer2 (57.42-145.17), p = 0.007. CONCLUSION: Liver elastic fiber density decreases with the reversal of NAFLD through weight loss.

Are Noninvasive Methods Comparable to Liver Biopsy in Postoperative Patients After Roux-en-Y Gastric Bypass?

INTRODUCTION: Transient tissue elastography (TTE) may estimate the degree of hepatic fibrosis in patients with obesity, but the method has restrictions that are mainly related to patients' BMI. PURPOSE: To compare the results of the evaluation of hepatic fibrosis by biochemical methods and TTE with those determined by liver biopsy in patients after RYGB. METHODS: This was a cross-sectional study involving patient data, TTE, and liver biopsy 1 year after RYGB. RESULTS: Of the 94 selected patients, 33 underwent TTE and liver biopsy. The average weight of patients was 84.4 ± 15.4 kg. The mean APRI was 0.2 ± 0.1, and 36 patients (97.3%) were classified as F0-F1. The average NFS was - 2.0 ± 1.0, with 25 patients (67%) classified as F0-F1 and 12 patients (32.4%) classified as F2. The agreement rate between Fibroscan and liver biopsy was 80.0%. Histological analysis revealed regression of inflammatory changes in all patients: 26 patients (72.2%) had some degree of non-alcoholic steatohepatitis (NAS ≥ 5), and after surgery, no patient presented inflammation upon biopsy. Nine patients (24.3%) had fibrosis at surgery, and only two (5.4%) still had fibrosis 1 year later (p < 0.008). CONCLUSIONS: The use of APRI and Fibroscan is promising, but more studies are needed to evaluate patients with an advanced degree of NAFLD and confirm the entire spectrum of the disease.

Tratamento cirúrgico da síndrome da artéria mesentérica superior em paciente idosa / Surgical treatment of mesenteric superior artery syndrome in an older woman

A síndrome da artéria mesentérica superior (SAM), ou síndrome de Wilkie, é uma afecção rara que acomete geralmente indivíduos jovens do sexo feminino. Caracterizada pela obstrução parcial ou completa do duodeno devido à compressão pela artéria mesentérica superior anteriormente, e pela aorta, posteriormente. Apresentamos um caso não usual de SAM, em paciente idosa, diagnosticado através de história clínica e imagem tomográfica característica. Indicou-se manejo cirúrgico de derivação jejunal e anastomose com duodeno acima da obstrução, na ciência do risco do procedimento. A paciente apresentou excelente evolução e encontra-se assintomática. O diagnóstico precoce, através de uma anamnese adequada e uso dos critérios radiológicos já definidos em literatura, podem afetar positivamente o desfecho dos pacientes portadores em qualquer faixa etária. (AU)

Superior mesenteric artery syndrome (SMAS), or Wilkie syndrome, is a rare condition that usually affects young women. It is characterized by partial or complete obstruction of the duodenum due to compression by the superior mesenteric artery anteriorly and by the aorta posteriorly. We report an unusual case of SMAS in an older woman diagnosed using clinical history and tomographic imaging. Surgical management consisting of jejunal shunt and anastomosis with duodenum above the obstruction was indicated despite the risk of the procedure. The outcome was excellent, and the patient is asymptomatic. Early diagnosis using adequate anamnesis and radiological criteria defined in the literature may positively influence the outcome of patients from any age group. (AU)

Collagen I and III in women with diastasis recti.

OBJECTIVES: Interest in elucidating the etiology of hernias has encouraged countless studies of musculoaponeurotic structures in individuals with and without hernias. Studies of hernia patients have firmly demonstrated a correlation between hernias and collagen alterations in their fascia. Diastasis recti is an increased width of the abdominal midline that is exclusively composed of interlacing aponeurotic expansions of the anterolateral abdominal muscles. The condition is common among women undergoing abdominoplasty, and many factors, not only mechanical, play a role. The goal of this study is to evaluate and compare collagen type I and III levels in the midline fascia of women with and without diastasis recti to report their possible influence on this condition. METHODS: This is a case-control study nested within a surgical cohort of 18 women with diastasis recti and 18 women without the condition (cases and controls, respectively). Fascia from the midline of the abdominal wall was collected and analyzed through immunohistochemistry using polyclonal antibodies to collagen type I and III. RESULTS: Both type I and type III collagen were less abundant in women with diastasis recti than in those without the condition, and the difference was statistically significant (p<0.001). CONCLUSION: Low collagen type I and type III levels in the midline of the abdominal wall may play a key role in the development of diastasis recti.

LINEA ALBA COLLAGEN ASSESSMENT IN MORBIDLY OBESE PATIENTS.

Background: The evaluation of collagen in the abdominal wall has been increasingly studied because of the relevance on collagen in the healing process after laparotomy. Aim: To evaluate the amount of collagen in the linea alba of patients undergoing laparotomic bariatric surgery and comparing with non-obese cadavers. Methods: Were evaluated 88 samples of aponeurosis from abdominal linea alba of 44 obese patients (obesity group) and 44 non-obese cadavers (control group). The samples were collected in 2013 and 2104, and were sorted according to age (18-30, 31-45 and 46-60), gender, BMI, waist and cervical circumference, and subcutaneous tissue thickness. Material for biopsy was collected from the supraumbilical region of the linea alba for immunohistochemical analysis differentiating collagen type 1 and type 3 and the 1/3 ratio. Image-Pro Plus pixel counting software was used to measure the amount of collagen. Results: The obesity group evidenced mean age 44.11±9.90 years; 18-30 age group had three (6.8%) obese individuals; 31-45 had 22 (50%) and 46-60 had 19 (43.1%). Females were present in 81.8% (n=36); BMI (kg/m²) was 48.81±6.5; waist circumference (cm) was 136.761±13.55; subcutaneous tissue thickness (cm) 4.873±0.916. Considering age groups, gender and BMI, there were statistical differences in all tests when compared with the cadavers. Conclusion: The amount of collagen in the linea alba above the umbilical region in the morbidly obese patients was smaller than in the non-obese cadavers in the same age group.

Racional: A avaliação do colágeno na parede abdominal é cada vez mais estudada, em virtude da relevância dele no processo cicatricial após laparotomia. Objetivo: Avaliar a quantidade de colágeno na linha alba de pacientes submetidos à cirurgia bariátrica e compará-la com a de cadáveres não-obesos. Métodos: Foram avaliados dois grupos com total de 88 amostras da aponeurose da linha alba abdominal, divididas em 44 de pacientes obesos (grupo obesidade) com indicação de cirurgia bariátrica e 44 de cadáveres não-obesos (grupo controle). As amostras foram retiradas da linha alba abdominal no período de 2013 a 2014 e inicialmente foram separadas conforme faixas etárias (18-30, 31-45 e 46-60), gênero, medidas de IMC, circunferência abdominal e cervical e espessura do subcutâneo do indivíduo. Foi coletado material para biópsia da linha alba supraumbilical para análise imunoistoquímica, diferenciando o colágeno tipo I e III e sua relação de tipo I/III. Utilizou-se o programa de contagem de pixels Image-Pro Plus(r), que mensurou a quantidade do colágeno. Resultados: O grupo obesidade teve idade 44,11±9,90 anos, Na faixa etária de 18-30 anos foram incluídos três (6,8%) obesos; na de 31-45 anos 22 (50%) e na de 46-60 anos 19 (43,1%). O gênero feminino apresentou predomínio, com 36 (81,8%) pacientes. O IMC (kg/m²) foi de 48,81±6,5; a circunferência abdominal (cm) foi de 136,761±13,55; a espessura do subcutâneo (cm) foi de 4,873±0,916. A quantidade de colágeno tipo I foi de 134.683,3±206.657,4; a de colágeno tipo III foi de 413.137,2±283.656,1; a razão do colágeno tipo I/III foi 0,419±0,636. Considerando-se faixas de idade, gênero e IMC, foram constatadas diferenças estatísticas em todas as análises quando comparadas com às dos cadáveres. Conclusão: Os obesos mórbidos apresentaram quantidade de colágeno na linha alba supraumbilical menor que a do grupo controle de cadáveres não-obesos na mesma faixa etária.
