RESUMO
BACKGROUND: Remnant gastric cancer (RGC) is defined as a carcinoma that develops in the gastric remnant from 5 years after gastrectomy, regardless of the primary gastric disease. The pattern of lymph node dissemination in these patients is not well understood. The present study aims to understand the lymph node distribution of patients with RGC in a single center. METHODS: In a total of 1380 patients with gastric cancer, between 1998 and 2020, 43 patients operated on for RGC were analyzed. The pattern of lymph node dissemination was evaluated based on the number of dissected lymph node stations, the number of positive lymph node stations, the positivity index at each analyzed station, the number of dissected lymph nodes per patient, and the positivity index per lymph node station. RESULTS: A mean of 13.0 ± 8.1 lymph nodes were dissected. The incidence of lymph node involvement by dissected station was higher at Stations 19, 11p, 3, 4sb and 7 (50, 40, 37.5, 36 and 31.7%, respectively). Among the positive dissected stations, Station 3 with 52.2%, 4sb with 39.1% and 4sa with 34.8% were the most affected. CONCLUSION: There was no predilection for lymph node involvement when comparing the lesser and greater gastric curvature. The dissection of Stations 3, 4sb and 4sa is fundamental in surgical treatment with curative purposes. The totalization of gastrectomy with lymphadenectomy of the perigastric and supra-pancreatic stations should be the surgery of choice.

BACKGROUND: Regarding postoperative pain, it remains unclear whether non-fixation of the polypropylene prosthesis in transabdominal preperitoneal inguinal hernia repair produces the same outcomes as mesh fixation with glue or tackers. In addition, hernia recurrence is another aspect to be assessed in the comparison between non-fixation and mesh-fixation techniques (tackers and glue). AIMS: This study aimed to evaluate the incidence, quality of pain, and recurrence in patients undergoing laparoscopic inguinal hernioplasty (transabdominal preperitoneal) technique, comparing the fixation of the mesh with tackers versus with glue versus without fixation. METHODS: This is a prospective, double-blind study in which 63 patients presenting with primary unilateral inguinal hernia underwent laparoscopic transabdominal preperitoneal inguinal hernia repair and were randomized into three groups: no mesh fixation (n=21), mesh tacked (n=21), and mesh fixed with fibrin glue (n=21). Patients also responded to questionnaires in order to assess pain and pain quality and were followed up for 2 years. RESULTS: Neither mesh-fixation nor non-fixation techniques were found to affect postoperative chronic pain (p=0.535), but patients undergoing tacker fixation reported more pain descriptors (p=0.0021) and a higher pain index (p=0.002) on the McGill scale in the first 15 postoperative days (T0 and T1). No hernia recurrences were observed. CONCLUSIONS: Both mesh-fixation techniques (tackers and glue) used with the transabdominal preperitoneal approach did not influence the onset of inguinodynia, but tacker fixation was more likely to increase patient sensitivity to pain. Mesh placement without fixation produced the same pain and recurrence outcomes as mesh-fixation techniques. Also, no recurrence was observed in patients without mesh fixation in this study. Consequently, it has become an alternative therapy deserving consideration for hernia repair.

OBJECTIVE: to describe the use of the robotic platform in inguinal hernia recurrence after a previous laparoscopic repair. METHODS: patients with recurrent inguinal hernias following a laparoscopic repair who have undergone robotic transabdominal preperitoneal between December 2015 through September 2020 were identified in a prospectively maintained database. Outcomes of interest included demographics, hernia characteristics, operative details and rates of 30-day surgical site occurrence, surgical site occurrences requiring procedural interventions, surgical site infection and hernia recurrence were abstracted. RESULTS: nineteen patients (95% male, mean age 55 years, mean body mass index 28) had 27 hernias repaired (N=8 bilateral). Average operative time was 168.9 ± 49.3min (range 90-240). There were two intraoperative complications all of them were bleeding from the inferior epigastric vessel injuries. Three SSOs occurred (N=2 seromas and N=1 hematoma. After a median 35.7 months follow-up (IQR 13-49), no recurrence has been diagnosed. One patient developed chronic postoperative inguinal pain. CONCLUSIONS: on a small number of selected patients and experienced hands, we found that the use of the robotic platform for repair of recurrent hernias after prior laparoscopic repair appears to be feasible, safe and effective despite being technically demanding. Further studies in larger cohorts are necessary to determine if this technique provides any benefits in recurrent inguinal hernia scenario.

RESUMO Objetivo: descrevemos nossa experiência com uso da plataforma robótica no tratamento das recidivas operadas previamente por laparoscopia, mantendo assim uma proposta minimamente invasiva a esses pacientes, apesar de haver uma predileção pela via anterior e aberta nestes casos. Métodos: foram incluídos pacientes submetidos a hernioplastia inguinal robótica transabdominal pré-peritoneal como tratamento de recidiva e que foram operados previamente por laparoscopia, entre dezembro de 2015 e setembro de 2020 e mantidos em uma base de dados ambulatorial prospectiva. Variáveis de interesse incluíram dados demográficos, características herniárias, detalhes operatórios, ocorrências do sítio cirúrgico em 30 dias (com ou sem necessidade de intervenção), infeção do sítio cirúrgico, tempo de seguimento e taxa de recidiva. Resultados: dezenove pacientes (95% masculino, média de idade de 55 anos, média de índice de massa corporal 28kg/m2) e 27 hérnias operadas (N=8 bilaterais). Média de tempo cirúrgico 168.9±49.3 min (variando 90-240). N=2 complicações intraoperatórias por lesão de vasos epigástricos inferiores. N=2 seromas e N=1 hematoma foram identificados no pós-operatório; N=1 paciente apresentou dor crônica pós operatória. Após um tempo de seguimento médio de 35.7 meses (intervalo entre quartis 13-49), nenhuma recidiva foi diagnosticada. Conclusões: o uso da plataforma robótica parece ser seguro e efetivo no tratamento das recidivas operadas previamente laparoscopia, nesse pequeno grupo de pacientes selecionados, apesar de requerer expertise em cirurgia robótica. Outros estudos com maiores casuísticas são necessários para estabelecer o papel desta técnica no cenário das hérnias inguinais recidivadas.

RESUMO RACIONAL: Em relação à inguinodinia, há que se perguntar se a não fixação da tela pela técnica da hernioplastia inguinal videolaparoscópica transbadominal pré-peritoneal teria os mesmos resultados em relação à fixação de telas com cola ou grampos. Além disso, a recorrência de hérnia é outro aspecto a ser avaliado na comparação entre as técnicas de não fixação e de fixação com tela (grampos e cola). OBJETIVOS: Avaliar a incidência, qualidade da dor e recorrência em pacientes submetidos à técnica de hernioplastia inguinal laparoscópica (transbadominal pré-peritoneal), comparando a fixação da tela com grampos vs. com cola vs. sem fixação. MÉTODOS: Este é um trabalho prospectivo, duplo-cego, em que 63 doentes portadores de hérnia inguinal submetidos à hernioplastia inguinal videolaparoscópica pela técnica transbadominal pré-peritoneal foram randomizados em três grupos: no primeiro a tela não foi fixada; no segundo foi fixada por grampos; e no terceiro foi fixada com cola. Estes pacientes foram submetidos a questionários para avaliação de dor, sendo acompanhados por dois anos. RESULTADOS: O método de fixação da tela, assim como a não fixação dela não interferiu no aparecimento da dor crônica pela Escala Visual Analógica; porém, os que foram submetidos à fixação por grampos tiveram mais descritores e índice de dor pela escala de McGill. Não foram observadas recidivas herniárias. CONCLUSÕES: O método de fixação da tela na técnica transbadominal pré-peritoneal não influencia no aparecimento da inguinodinia. A não fixação teve os mesmos resultados em termos de dor e recidiva, tornando-se alternativa terapêutica a ser considerada, pois não acarretou recidivas.
RESUMO
INTRODUCTION/PURPOSE: Obesity increases significantly every year worldwide. Since 1980, the prevalence of individuals with obesity has practically doubled. Obesity plays an important role in the pathophysiology of diseases that arise from a complex interaction of nutritional, genetic, and metabolic factors, characterizing a chronic inflammatory state. This study aimed to verify the systemic inflammatory response through the analysis of IGF-1, IL-23, and resistin levels and the lipid profile in severely obese women undergoing surgery for obesity and weight-related diseases. MATERIALS AND METHODS: This randomized controlled clinical trial includes female patients clinically diagnosed with severe obesity with an indication for bariatric surgery. RESULTS: In the initial evaluation, no significant difference was observed between the control (CG) and bariatric surgery (BSG) groups. The weight, BMI, systolic and diastolic blood pressures, total cholesterol, LDL, HDL, total non-HDL cholesterol, and glucose in BSG patients showed a significant change after surgery. Pre- and post-surgery levels of resistin, IGF-1, and IL-23 showed a significant difference in the BSG group, but only IL-23 was changed after 6 months in the CG. CONCLUSION: The results of this study confirmed that weight loss induced by surgery for obesity and weight-related diseases improved the lipid profile and reduced the chronic inflammatory status in women with severe obesity.

BACKGROUND: Since the publication of the first Brazilian Consensus on Gastric Cancer (GC) in 2012 carried out by the Brazilian Gastric Cancer Association, new concepts on diagnosis, staging, treatment and follow-up have been incorporated. AIM: This new consensus is to promote an update to professionals working in the fight against GC and to provide guidelines for the management of patients with this condition. METHODS: Fifty-nine experts answered 67 statements regarding the diagnosis, staging, treatment and prognosis of GC with five possible alternatives: 1) fully agree; 2) partially agree; 3) undecided; 4) disagree and 5) strongly disagree A consensus was adopted when at least 80% of the sum of the answers "fully agree" and "partially agree" was reached. This article presents only the responses of the participating experts. Comments on each statement, as well as a literature review, will be presented in future publications. RESULTS: Of the 67 statements, there was consensus in 50 (74%). In 10 declarations, there was 100% agreement. CONCLUSION: The gastric cancer treatment has evolved considerably in recent years. This consensus gathers consolidated principles in the last decades, new knowledge acquired recently, as well as promising perspectives on the management of this disease.
