Résumé
Introducción. El cáncer gástrico en Colombia es la segunda neoplasia más común en hombres y la cuarta en mujeres. En los últimos años se han descrito ampliamente los beneficios del abordaje laparoscópico en el cáncer gástrico frente a sangrado, recuperación postoperatoria y complicaciones, sin afectar los resultados oncológicos. Métodos. Estudio observacional retrospectivo de pacientes llevados a gastrectomía laparoscópica en la Clínica Universitaria Colombia durante un período de diez años, entre 2013 y 2023. Se describieron los resultados perioperatorios en cuanto a estancia hospitalaria, sangrado operatorio, duración del procedimiento, complicaciones, causas de reintervención y mortalidad en los primeros 30 días. Resultados. Se incluyeron 418 pacientes, 58,9 % hombres, con una edad promedio de 60,8 años. Se documentó un tiempo quirúrgico promedio de 228,7 minutos, con un sangrado de 150 ml. La media de ganglios linfáticos resecados fue de 26,1 ± 11,4. La estancia hospitalaria en promedio fue de 4 ± 4 días, y se registraron complicaciones en 104 sujetos, con una tasa promedio de 24 %, de las cuales 29 (27,4 %) obtuvieron una clasificación Clavien-Dindo IIIB. Conclusiones. La gastrectomía por laparoscopia en un centro de alto volumen y con cirujanos experimentados en Colombia, tiene resultados perioperatorios similares a lo reportado en la literatura mundial. Aún se requiere de estudios de mayor fuerza de asociación para establecer recomendaciones sobre el uso rutinario de este abordaje en patología maligna avanzada.
Introduction. Gastric cancer in Colombia is the second most common neoplasm in men and the fourth in women. In recent years, the benefits of the laparoscopic approach in gastric cancer against bleeding, postoperative recovery com and complications have been widely described, without affecting oncological results. Methods. Retrospective observational study of patients undergoing laparoscopic gastrectomy at the Clínica Universitaria Colombia over a period of ten years, between 2013 and 2023. Perioperative results were described in terms of hospital stay, operative bleeding, duration of the procedure, complications, causes of reintervention, and mortality in the first 30 days. Results. 418 patients were included, 58.9% men, with an average age of 60.88 years. An average surgical time of 228.7 minutes was documented, with a blood loss of 150 ml. The mean number of lymph nodes resected was 26.1 ± 11.4. The average hospital stay was 4 ± 4 days, and complications were recorded in 104 subjects, with an average rate of 24%, of which 29 (27.4%) obtained a Clavien-Dindo IIIB classification. Conclusions. Laparoscopic gastrectomy in a high-volume center and with experienced surgeons in Colombia has perioperative results similar to those reported in the world literature. Studies with greater strength of association are still required to establish recommendations on the routine use of this approach in advanced malignant pathology.

El cáncer gástrico (CG), es la primera causa de muerte por cáncer, en hombres, y la tercera en mujeres, en Chile. No obstante ello, el CG bifocal (CGB) es una situación poco frecuente. El objetivo de este manuscrito fue reportar un caso de CGB, con linfonodos negativos en un paciente con cirrosis hepática, que fue intervenido quirúrgicamente; y revisar la evidencia existente respecto de sus características morfológicas, terapéuticas y pronósticas. Caso clínico: Hombre de 74 años diabético, hipertenso, insuficiente cardíaco y cirrótico; portador de CGB (subcardial y antro-pilórico), diagnosticado por endoscopia y con confirmación histológica de ambas lesiones; operado en Clínica RedSalud Mayor Temuco en septiembre de 2023. En el intraoperatorio se verificó además la coexistencia de una lesión de aspecto metastásico en el segmento III del hígado, y adhesión de la región antro-pilórica a la vesícula biliar. Se realizó gastrectomía total, linfadenectomía D2, esófago-yeyuno anastomosis término-lateral, resección segmentaria hepática (segmento III) y colecistectomía. El paciente permaneció 6 días en la UCI debido a que desarrolló insuficiencia hepática (encefalopatía leve y ascitis). Se alimentó vía enteral por sonda naso-yeyunal. Posteriormente inició alimentación oral progresiva, la que fue bien tolerada. Completó 11 días de hospitalización en servicio médico-quirúrgico, donde mejoró actividad neurológica, hasta su alta domiciliaria. Actualmente, lleva dos meses desde su operación, se encuentra en buenas condiciones generales, y el Comité Oncológico decidió no dar quimioterapia adyuvante. Se presenta un caso inusual de CG de tipo bifocal, respecto de lo cual hay escasa información disponible. Se logró realizar cirugía con intención curativa en un paciente de alto riesgo, con un resultado exitoso.
SUMMARY: Gastric cancer (GC) is the first cause of death from cancer in men, and the third one in women, in Chile. However, a bifocal GC (BGC) is uncommon. The aim of this study was to report a case of CGB, with negative-lymph nodes in a patient with liver cirrhosis, who underwent surgery; and review the existing evidence regarding its morphological, therapeutic and prognostic characteristics. Clinical case: A 74-year-old male patient with a medical history of diabetes, hypertension, congestive heart failure, and cirrhosis underwent surgical intervention for GC located in subcardial and antro- pyloric regions. The diagnosis was established via endoscopy and confirmed histologically. Surgery was performed at the RedSalud Mayor Temuco Clinic in September 2023. During intraoperative assessment, the coexistence of a lesion with metastatic-like characteristics in segment III of the liver was also verified, along with adhesions between the antro-pyloric region and the gallbladder. Surgical approach encompassed total gastrectomy, D2 lymphadenectomy, esophago-jejunostomy, segmental hepatic resection, and cholecystectomy. Subsequently, the patient required a six-day stay in ICU due to the development of hepatic insufficiency, characterized by mild encephalopathy and ascites. Enteral nutrition was administered via a naso-jejunal tube, followed by a gradual transition to oral feeding, which was well-tolerated. The patient completed an 11-day hospitalization period in the medical-surgical ward, during which his neurological function improved significantly, resulting in his discharge. At present, 2 months post-surgery, the patient remains in satisfactory general health, and the Oncology Committee decided not to proceed with adjuvant chemotherapy. This case represents a rare instance of bifocal GC, for which there is limited available literature. Surgical intervention with curative intent was successfully carried out in a high-risk patient, yielding a positive outcome.

Introducción. La gastrectomía y disección ganglionar es el estándar de manejo para los pacientes con cáncer gástrico. Factores como la identificación de ganglios por el patólogo, pueden tener un impacto negativo en la estadificación y el tratamiento. El objetivo de este estudio fue comparar el recuento ganglionar de un espécimen quirúrgico después de una gastrectomía completa (grupo A) y de un espécimen con un fraccionamiento por grupos ganglionares (grupo B). Métodos. Estudio de una base de datos retrospectiva de pacientes sometidos a gastrectomía D2 en el Servicio de Cirugía gastrointestinal de la Liga Contra el Cáncer seccional Risaralda, Pereira, Colombia. Se comparó el recuento ganglionar en especímenes quirúrgicos con y sin división ganglionar por regiones anatómicas previo a su envío a patología. Resultados. De los 94 pacientes intervenidos, 65 pertenecían al grupo A y 29 pacientes al grupo B. El promedio de ganglios fue de 24,4±8,6 y 32,4±14,4 respectivamente (p=0,004). El porcentaje de pacientes con más de 15 y de 25 ganglios fue menor en el grupo A que en el grupo B (27 vs 57, p=0,432 y 19 vs 24, p=0,014). El promedio de pacientes con una relación ganglionar menor 0,2 fue mayor en el grupo B (72,4 % vs 55,4 %, p=0,119). Conclusiones. Los resultados de nuestro estudio mostraron que una división por grupos ganglionares previo a la valoración del espécimen por el servicio de patología incrementa el recuento ganglionar y permite establecer de manera certera el pronóstico de los pacientes, teniendo un impacto positivo en su estadificación, para evitar el sobretratamiento
Introduction. A gastrectomy and lymph node dissection is the standard of management for patients with gastric cancer. Factors such as the identification of nodes by the pathologist can have a negative impact on staging and treatment. The objective of this study was to compare the lymph node count of a surgical specimen after a complete gastrectomy (group A) and of a specimen with lymph node by groups (group B). Methods. Study of a retrospective database of patients undergoing D2 gastrectomy in the Risaralda section of the Liga Contra el Cancer Gastrointestinal surgical service, Pereira, Colombia. The lymph node count was compared in surgical specimens with and without lymph node division by anatomical regions, prior to sending them to pathology. Results. Of the 94 patients who underwent surgery, 65 were from group A and 29 patients were from group B. The average number of nodes was 24.4±8.6 and 32.4±14.4, respectively (p=0.004). The percentage of patients with more than 15 and 25 nodes was lower in group A than in group B (27 vs 57, p=0.432 and 19 vs 24, p=0.014). The average number of patients with a nodal ratio less than 0.2 was higher in group B (72.4% vs 55.4%, p=0.119). Conclusions. The results of our study showed that a division by lymph node groups prior to the evaluation of the specimen by the pathology service increases the lymph node count and allows the prognosis of patients to be accurately established, having a positive impact on their staging, to avoid overtreatment.

ABSTRACT BACKGROUND: Insufficient research exists on the stapling technique in and duration of laparoscopic sleeve gastrectomy (LSG). OBJECTIVES: This study aimed to assess the clinical outcomes using a 30-second precompression and post-firing waiting time without extra support for the stapling line. DESIGN AND SETTINGS: Randomized controlled prospective study at a university hospital. METHODS: This study included 120 patients treated between January 2022 and February 2023. The patients were divided into the non-waiting group (T0) and waiting group (T1), each with 60 patients. Perioperative complications were analyzed using statistical tests. RESULTS: The waiting group (T1) showed a significant reduction in the number of intraoperative bleeding points requiring intervention compared with the non-waiting group (T0) (81 versus 134, P < 0.05). In T0, postoperative C-reactive protein (CRP) levels increased (P < 0.05) and hemoglobin levels decreased significantly (P <0.05). The study recorded 22 postoperative complications, accounting for 18.3% of all cases during the 30-day postoperative period. CONCLUSIONS: The study concluded that the 30 sec + 30 sec stapling technique reduces perioperative bleeding, length of stay, and serious complication rates and is practical and effective for LSG. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov with registration code NCT05703035; link: https://clinicaltrials.gov/ct2/show/NCT05703035.
Résumé
ABSTRACT BACKGROUND: Curative treatment for gastric cancer involves tumor resection, followed by transit reconstruction, with Roux-en-Y being the main technique employed. To permit food transit to the duodenum, which is absent in Roux-en-Y, double transit reconstruction has been used, whose theoretical advantages seem to surpass the previous technique. AIMS: To compare the clinical evolution of gastric cancer patients who underwent total gastrectomy with Roux-en-Y and double tract reconstruction. METHODS: A systematic review was carried out on Web of Science, Scopus, EmbasE, SciELO, Virtual Health Library, PubMed, Cochrane, and Google Scholar databases. Data were collected until June 11, 2022. Observational studies or clinical trials evaluating patients submitted to double tract (DT) and Roux-en-Y (RY) reconstructions were included. There was no temporal or language restriction. Review articles, case reports, case series, and incomplete texts were excluded. The risk of bias was calculated using the Cochrane tool designed for randomized clinical trials. RESULTS: Four studies of good methodological quality were included, encompassing 209 participants. In the RY group, there was a greater reduction in food intake. In the DT group, the decrease in body mass index was less pronounced compared to preoperative values. CONCLUSIONS: The double tract reconstruction had better outcomes concerning body mass index and the time until starting a light diet; however, it did not present any advantages in relation to nutritional deficits, quality of life, and post-surgical complications.
RESUMO RACIONAL: O tratamento curativo do câncer gástrico envolve a ressecção do tumor, seguida de reconstrução do trânsito, sendo o Y-de-Roux a principal técnica empregada. Para permitir o trânsito alimentar para o duodeno, ausente em Y-de-Roux, tem-se utilizado a reconstrução de duplo trânsito, cujas vantagens teóricas parecem superar a técnica anterior. OBJETIVOS: Comparar a evolução clínica de pacientes com câncer gástrico submetidos à gastrectomia total com Y-de-Roux e reconstrução de duplo trânsito. MÉTODOS: Foi realizada uma revisão sistemática nas bases de dados: Web of Science, Scopus, Embase, Scielo, Biblioteca Virtual em Saúde, PubMed e Cochrane. Os dados foram coletados até 11 de junho de 2022. Foram incluídos estudos observacionais ou ensaios clínicos avaliando pacientes que utilizaram reconstruções de duplo trânsito (DT) e Y-de-Roux (RY). Não houve restrição temporal ou de idioma. Foram excluídos artigos de revisão, relatos de casos, séries de casos e aqueles com texto incompleto. O risco de viés foi calculado utilizando a ferramenta Cochrane desenvolvida para ensaios clínicos randomizados. RESULTADOS: Foram incluídos quatro estudos de boa qualidade metodológica, abrangendo 209 participantes. No grupo RY houve maior redução na ingestão alimentar. No grupo DT, a diminuição do índice de massa corporal (IMC) foi menos pronunciada em comparação aos valores pré-operatórios. CONCLUSÕES: A reconstrução de duplo trânsito apresentou melhores resultados em relação ao índice de massa corporal e ao tempo para início de dieta leve, porém não apresentou vantagens em relação aos déficits nutricionais, qualidade de vida e complicações pós-cirúrgicas.
Résumé
Abstract Background: The aim of this study was to compare metabolic parameters, plasma Osteopontin (OPN) and Hepatocyte Growth Factor (HGF) levels between Sleeve Gastrectomy (SG) patients in their 6th post-operation month and healthy control patients. Methods: Height, weight, Body Mass Index (BMI) and laboratory parameters of 58 SG patients aged 18‒65 years (Group 1) and 46 healthy control patients (Group 2) were compared. In addition, preoperative and postoperative sixth-month BMI and laboratory parameters of the patients in Group 1 were compared. Results: The mean age and gender distributions of the groups were similar (p > 0.05). Mean BMI was 28.9 kg/m2 in Group 1 and 27 kg/m2 in Group 2 (p < 0.01). While plasma HGF levels were similar between both groups, plasma OPN levels were higher in Group 2 (p < 0.001). Fasting plasma glucose, total cholesterol, triglyceride, fasting plasma insulin and insulin resistance values were higher in Group 1, while alanine aminotransferase and aspartate aminotransferase levels were higher in Group 2 (p < 0.05). There was a strong correlation between plasma HGF and OPN levels in Group 1, but not in Group 2 (Rho = 0.805, p < 0.001). Conclusion: OPN and HGF are promising biomarkers that can be used to better understand and detect problems related to obesity. The fact that patients in the early post-SG period had lower plasma OPN and similar plasma HGF compared to non-surgical patients of similar age and gender with higher BMI may be another favorable and previously unknown metabolic effect of SG.
Résumé
ABSTRACT BACKGROUND: Predicting short- and long-term outcomes of oncological therapies is crucial for developing effective treatment strategies. Malnutrition and the host immune status significantly affect outcomes in major surgeries. AIMS: To assess the value of preoperative prognostic nutritional index (PNI) in predicting outcomes in gastric cancer patients. METHODS: A retrospective cohort analysis was conducted on patients undergoing curative-intent surgery for gastric adenocarcinoma between 2009 and 2020. PNI was calculated as follows: PNI=(10 x albumin [g/dL])+(0.005 x lymphocytes [nº/mm3]). The optimal cutoff value was determined by the receiver operating characteristic curve (PNI cutoff=52), and patients were grouped into low and high PNI. RESULTS: Of the 529 patients included, 315 (59.5%) were classified as a low-PNI group (PNI<52) and 214 (40.5%) as a high-PNI group (PNI≥52). Older age (p=0.050), male sex (p=0.003), American Society of Anesthesiologists score (ASA) III/IV (p=0.001), lower hemoglobin level (p<0.001), lower body mass index (p=0.001), higher neutrophil-lymphocyte ratio (p<0.001), D1 lymphadenectomy, advanced pT stage, pN+ and more advanced pTNM stage were related to low-PNI patient. Furthermore, 30-day (1.4 vs. 4.8%; p=0.036) and 90-day (3.3 vs. 10.5%; p=0.002) mortality rates were higher in low-PNI compared to high-PNI group. Disease-free and overall survival were worse in low-PNI patients compared to high-PNI (p<0.001 for both). ASA III/IV score, low-PNI, pT3/T4, and pN+ were independent risk factors for worse survival. CONCLUSIONS: Preoperative PNI can predict short- and long-term outcomes of patients with gastric cancer after curative gastrectomy. Low PNI is an independent factor related to worse disease-free and overall survival.
RESUMO RACIONAL: Estimar os desfechos de curto e longo prazo das terapias contra o câncer é crucial para o desenvolvimento de estratégias de tratamento eficazes. A desnutrição e o estado imunológico do hospedeiro afetam significativamente os desfechos em cirurgias de grande porte. OBJETIVOS: Avaliar o valor do índice nutricional prognóstico pré-operatório (INP) na predição de desfechos em pacientes com câncer gástrico. MÉTODOS: Foi realizada uma análise de coorte retrospectiva de pacientes submetidos à cirurgia com intenção curativa para adenocarcinoma gástrico entre 2009 e 2020. O INP foi calculado da seguinte forma: INP=(10 x albumina [g/dL])+(0.005 x linfócitos [nº/mm3]). O valor de corte ideal foi determinado pela curva característica de operação do receptor (ponto de corte do INP=52), e os pacientes foram agrupados em INP baixo ou alto. RESULTADOS: Dos 529 pacientes incluídos, 315 (59,5%) foram classificados como grupo de baixo INP (INP<52) e 214 (40,5%) como grupo de alto INP (INP>52). Idade mais avançada (p=0,050), sexo masculino (p=0,003), escore da Sociedade Americana de Anestesiologistas (ASA) III/IV (p=0,001), menor nível de hemoglobina (p<0,001), menor índice de massa corpórea (p=0,001), maior relação neutrófilos-linfócitos (p<0,001), linfadenectomia D1, estágio pT avançado, pN+ e estágio pTNM mais avançado foram relacionados ao paciente com baixo INP. Além disso, as taxas de mortalidade em 30 dias (1,4 vs. 4,8%; p=0,036) e em 90 dias (3,3 vs. 10,5%; p=0,002) foram maiores no grupo com baixo PNI em comparação ao grupo com alto INP. A sobrevida livre de doença e a sobrevida global foram piores em pacientes com baixo INP em comparação com pacientes com alto INP (p<0,001 para ambos). Escore ASA III/IV, baixo INP, pT3/T4 e pN+ foram fatores de risco independentes para pior sobrevida. CONCLUSÕES: O INP pré-operatório pode predizer desfechos de curto e longo prazo de pacientes com câncer gástrico após gastrectomia curativa. Baixo INP é um fator independente relacionado a piores sobrevida livre de doença e sobrevida global.
Résumé
ABSTRACT Introduction: Gastric cancer is still the third cause of death worldwide due to malignant neoplasms. Its prognostic indices have not yet been well defined for surgical intervention in terms of stratifying the intensity of chronic inflammation. The Glasgow Prognostic Score (GPS) and O-POSSUM and P-POSSUM Indices may constitute these standardizations and were tested to assess the association between them and the prognosis after curative gastrectomy. Method: Retrospective observational study, analysing medical records of patients with gastric adenocarcinoma who underwent gastrectomy, from 2015 to 2021, in two hospitals in Rio de Janeiro. Surgical extension, pre, peri and postoperative clinical and laboratory data were observed, up to 30 days after surgery. Patients were layered by GPS and compared according to the Clavien-Dindo (CD) classification. Logistic regression was performed to test the association between the outcome and independent variables. Results: Of the 48 patients, 56.25% were female. There was difference between the groups regarding surgical extension and GPS (both with p<0.001), while O-POSSUM, P-POSSUM and age showed no difference. Factors associated with CD ≥ III-a complication in the univariate analysis were GPS (OR: 85,261; CI: 24,909- 291,831) and P-POSSUM (OR: 1,211; CI:1,044-1,404). In the multivariate analysis, the independent factors associated with CD ≥ III-a were GPS (OR:114,865; CI: 15,430-855,086), P-POSSUM (OR: 1,133; CI: 1,086-1,181) and O-POSSUM (OR: 2,238; CI: 1,790-2,797). Conclusion: In this model, GPS, P-POSSUM and O-POSSUM predicted serious surgical complications. There is a need for further studies to establish strategies to minimize the inflammatory response in the preoperative period.
RESUMO Introdução: O câncer gástrico segue como terceira causa de mortalidade mundial por neoplasias malignas. Seus índices prognósticos ainda não foram bem definidos para intervenção cirúrgica quanto à estratificação da intensidade da inflamação crônica. Os Critérios Prognósticos de Glasgow (CPG) e os índices de O-POSSUM e PPOSSUM podem constituir essas padronizações e foram testados para avaliar a associação entre eles e o prognóstico após gastrectomia curativa. Método: Estudo retrospectivo, analisando prontuários de pacientes com adenocarcinoma gástrico e submetidos à gastrectomia, no período de 2015 até 2021, em dois hospitais no Rio de Janeiro. Foram observados a extensão cirúrgica, os dados clínicos e laboratoriais pré, peri e pós-operatórios, até 30 dias após a cirurgia. Os pacientes foram estratificados pelos CPG e comparados segundo classificação de ClavienDindo (CD). Regressão logística foi realizada para testar associação entre o desfecho e variáveis independentes. Resultados: Dos 48 doentes, 56,25% eram do sexo feminino. Houve diferença entre os grupos quanto à extensão cirúrgica e CPG (ambos com p<0,001), enquanto O-POSSUM, P-POSSUM e idade não apresentaram diferença. Fatores associados com complicação CD ≥ III-a na análise univariada foram CPG (OR: 85,261; IC: 24,909-291,831) e P-POSSUM (OR: 1,211; IC: 1,044-1,404). Na análise multivariada, os fatores independentes associados ao CD ≥ III-a foram CPG (OR: 114,865; IC: 15,430-855,086), P-POSSUM (OR: 1,133; IC: 1,086-1,181) e O-POSSUM (OR: 2,238; IC: 1,790-2,797). Conclusão: Neste modelo, CPG, P-POSSUM e O-POSSUM previram complicações cirúrgicas graves. Há necessidade de estudos mais aprofundados para instituir estratégias de forma a minimizar a resposta inflamatória no período pré-operatório.

Objective:To analyze the short-term clinical outcomes of total laparoscopic distal gastrectomy (TLDG) and laparoscopic-assisted distal gastrectomy (LADG) combined with Billroth-Ⅱ+Braun anastomosis.Methods:Clinical characteristics of patients undergoing laparoscopic distal gastrectomy combined with Billroth-Ⅱ+Braun anastomosis at Department of Gastrointestinal Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University from Jan 2020 to Oct 2022 were analyzed. Patients were divided into TLDG group ( n=62) and LADG group ( n=62) according to the surgical approach. Results:There were significant differences in the preoperative clinical data section between the two groups, and 124 patients (62 in each group) were enrolled after using propensity score matching to balance significant variables. Compared with the LADG group, the TLDG group showed statistically differences in time to first venting [(2.9±1.3) vs. (2.3±0.8) d, Z=-3.072, P=0.002], time to first fluid diet [(5.9±1.3) vs. (5.4±1.4) d, Z=-2.031, P=0.042] and incision length [(7.1±1.4) vs. (4.8±0.8) cm, Z=-6.331, P=0.000]. Total postoperative complication rate in the TLDG group and the LADG group (29% vs. 37%, χ2=0.911, P=0.340) was not statistically significant. Incidence of postoperative pneumonia was lower in the TLDG group than in the LADG group (3% vs. 13%, χ2=3.916, P=0.048), and incidence of all remaining postoperative complications were not statistically significant. There was no statistically significant difference in the incidence of serious postoperative complications between the TLDG and LADG groups ( P=1.000). Multifactorial analysis revealed that male ( P=0.023) and age ≥65 years ( P=0.001) were independent risk factors for postoperative complications. Conclusion:TLDG is safe and feasible and has better short-term clinical efficacy than LADG.

Objectives:To explore the Clavien-Dindo (CD) classfication of short-term (within 30 days postoperative) complications of distal major gastrectomy (DG) and the associated risk factors affecting this classification.Methods:A retrospective analysis was conducted on the clinical data of 230 patients with gastric cancer who underwent DG completed by the same operator at Beijing Friendship Hospital, Capital Medical University from January 2016 to December 2021. There were 159 males (69.1%) and 71 females (30.9%), aged from 31 to 80 years, with an average age of (61.69±10.91) years, all patients average body mass index was (23.59±3.46) kg/m 2. Chi-square test or Fisher exact probability method was used to compare the count data between groups, and rank sum test was used to compare the rank data between groups. Multiple factors were analyzed by stepwise Logistic regression. Results:In this study, a total of 30 cases (13.0%) experienced CD grade Ⅱ or higher postoperative complications. Among them, 20 cases (66.7%) were grade Ⅱ, 8 cases (26.7%) were grade Ⅲ, and 2 cases (6.6%) were grade Ⅳ, Among the 30 patients with complications, there were 2 cases of simple anastomotic leakage, 2 cases of anastomotic bleeding, 3 cases of duodenal stump leakage, 2 cases of intra-abdominal infection, 6 cases of intestinal obstruction, 5 cases of pulmonary infection, 2 cases of incision infection, 2 cases of delayed gastric emptying, 3 cases of pulmonary infection combined with atelectasis, 2 cases of anastomotic leakage combined with intra-abdominal infection, and 1 case of pulmonary infection and intra-abdominal infection combined with intestinal obstruction. Pulmonary infection, intestinal obstruction, and anastomotic leakage were the main postoperative complications of DG. The surgical approach was an independent risk factor for postoperative complications ( P<0.05), and there was no statistically significant difference in the grade of postoperative complications of patients with different surgical methods( P>0.05). Conclusions:Pulmonary infection, intestinal obstruction, abdominal infection, and anastomotic leakage are the main postoperative complications of DG. The independent risk factor for complications is the surgical approach, but the surgical approach does not affect the CD grading of complications.

Objective:To explore the efficacy and safety of laparoscopic technology in the treatment of gastric cancer which using proximal subtotal gastrectomy and distal subtotal gastrectomy.Methods:A retrospective analysis was conducted on the clinical data of 98 gastric cancer patients admitted to the Department of General Surgery, General Hospital of Huainan Eastern Hospital Group from January 2016 to January 2020, including 71 males and 27 females with an average age of (62.03±10.6) years old(ranged from 32 to 80 years). All cases were divided into proximal group ( n=28) and distal group ( n=70) according to different surgical methods. The proximal group was treated with laparoscopic proximal subtotal gastrectomy, while the distal group was treated with laparoscopic distal subtotal gastrectomy. SPSS 20.0 software was used to analyze the differences in surgical related clinical indicators, postoperative complications, nutritional status, quality of life, and survival rate between two groups. Kaplan-Merier was used to draw survival curves, and Log-rank test was used to compare the survival differences between the two groups. Results:The number of lymph node dissection in the proximal group was less than that in the distal group, and the difference was statistically significant ( t=2.02, P=0.045). The incidence rate of reflux esophagitis in the proximal group was higher than that in the distal group (57.14% vs 4.29%, χ2=35.75, P<0.001), the incidence rate of reflux gastritis was lower than that of the distal group, the difference was statistically significant(3.57% vs 22.86% P=0.035). The levels of red blood cells, hemoglobin, and albumin in the proximal group were lower than those in the distal group after surgery, and the differences were statistically significant ( t=2.62, P=0.010; t=2.12, P=0.036; t=3.54, P=0.001). One month after surgery, the Karnofsky functional status score in the proximal group was lower than that in the distal group, and the difference was statistically significant ( t=2.27, P=0.025). The postoperative 1, 3, and 5-year survival rates of the proximal group were 85.71%, 64.29%, and 46.43%, respectively, while the postoperative 1, 3, and 5-year survival rates of the distal group were 88.57%, 71.43%, and 57.14%, respectively. There was no statistically significant difference in the survival curves between the two groups ( P>0.05). Conclusions:The incidence rate of reflux esophagitis after laparoscopic proximal subtotal gastrectomy is higher than that of distal subtotal gastrectomy, and the number of lymph nodes cleared during operation is less than that of distal subtotal gastrectomy. Compared with laparoscopic distal subtotal gastrectomy, the nutritional status of patients after proximal subtotal gastrectomy is significantly worse, but there is no significant difference in long-term survival rate between the two groups.

Objective:To investigate the effect of the explain-simulate-practice-communication-support (ESPCS) nursing model on perioperative stress and postoperative rehabilitation in patients undergoing laparoscopic radical gastrectomy for gastric cancer. Provide a basis for the application of ESPCS nursing model in patients undergoing radical gastrectomy for gastric cancer.Methods:This was a quasi-experimental study. A total of 212 patients who underwent laparoscopic radical gastrectomy for gastric cancer in the First Affiliated Hospital of China Medical University from May 2019 to May 2023 were selected by convenience sampling and divided into the observation group and the control group by random digital table method, with 106 patients in each group. The control group received routine nursing intervention, while the observation group received ESPCS nursing intervention for 3 months. The perioperative stress hormones (serum cortisol and epinephrine), Self-rating Depression Scale (SDS) score, Self-rating Anxiety Scale (SAS) score, gastrointestinal function indicators, and the 36-item Short Form Health Survey Questionnaire (SF-36) score were compared between the two groups.Results:Two groups of patients were lost to follow-up, with a total of 104 patients in each group. The control group consisted of 65 males and 39 females, aged (61.59 ± 3.42) years old, while the observation group consisted of 61 males and 43 females, aged (60.78 ± 3.63) years old. Six days after operation, serum cortisol and epinephrine levels in the observation group were (221.46 ± 24.15) nmol/L and (28.11 ± 3.47) pmol/L, respectively, which were lower than those in the control group (261.84 ± 27.91) nmol/L and (31.49 ± 3.86) pmol/L, respectively, and the differences were statistically significant ( t=11.16, 6.64, both P<0.05). After 1 week of operation, the SDS and SAS scores in the observation group were (41.39 ± 2.21), (39.62 ± 2.31) points, respectively, which were lower than those in the control group (45.27 ± 2.34), (44.35 ± 2.37) points, and the differences were statistically significant ( t=12.29, 14.58, both P<0.05). The time of first exhaust, first defecation, intestinal ringing and first solid eating in the observation group were (55.38 ± 6.23), (68.84 ± 7.92), (38.73 ± 4.31), (62.31 ± 7.67) h, respectively, which were lower than those in the control group (67.51 ± 8.39), (84.17 ± 9.25), (48.43 ± 5.79), (75.65 ± 8.52) h, the differences were statistically significant ( t values were 11.84-13.71, all P<0.05).

Résumé
Objective:To investigate the application value of biological muscle flap in laparo-scopic radical proximal gastrectomy with esophagogastric anastomosis.Methods:The retrospec-tive and descriptive study was conducted. The clinicopathological data of 10 patients with adeno-carcinoma of esophagogastric junction who were admitted to The First Affiliated Hospital of Xi′an Jiaotong University from May 2023 to August 2023 were collected. All patients were males, aged (65±5)years. All patients underwent laparoscopic radical proximal gastrectomy and esophagogastric anastomosis with digestive tract reconstruction using the esophagogastric biological muscle flap. Observation indicators: (1) surgical situations and early complications; (2) follow-up and late com-plications. Measurement data with normal distribution were represented as Mean± SD, and measure-ment data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations and early complications. All 10 patients success-fully completed the surgery without conversion to open surgery, and the operation time was (166±18)minutes. Cases with digestive tract reconstruction as end-to-side anastomosis and Overlap anas-tomosis were 1 and 9, respectively. The time of digestive tract reconstruction, the number of lymph node dissected, volume of intraoperative blood loss, time to postoperative first anal exhaust, time to postoperative first intake of liquid food, duration of postoperative hospital stay were (40±12)minutes, 24±6, (41±9)mL, (3.4±0.5)days, (4.1±1.0)days, (8.3±0.7)days in the 10 patients. Of 4 cases with postoperative early complications, 1 case developed pulmonary infection (Clavien-Dindo grade Ⅱ) on the second day after surgery, with pulmonary infection absorbed after 5 days of antibiotic treat-ment. Two cases experienced chest distress and shortness of breath on the third day after surgery, with the diagnosis of a small to moderate amount of pleural effusion after chest B-ultrasound examination. After pleural puncture and active treatment, the symptoms of them were improved and the pleural effusion disappeared. There was 1 case with choking sensation when eating solid food, which was started from the third week after surgery. Upper gastrointestinal imaging revealed mild anastomotic stenosis of Clavien-Dindo grade Ⅰ in the patient, who was improved after conservative treatment. On the 7th day after surgery, all 10 patients underwent upper gastrointestinal angiography, and no anastomotic leakage or stenosis occurred. There was no sign of contrast agent reflux in the supine position and 30° head down position. (2) Follow-up and late complications. All 10 patients were followed up for 59.5(range, 31.0-127.0)days. The esophageal reflux scale score of 10 patients was 1.4±0.3. During the follow-up, 1 case underwent gastroscopy on 40 days after surgery, which showed reflux esophagitis with Los Angeles grade as B and the Clavien-Dindo grade as Ⅰ. There was no clinical symptom such as heartburn or acid reflux. Results of 24-hour pH monitoring showed that the patient experienced 24 instances of reflux in an upright position and 15 instances of reflux in a supine position, with no prolonged reflux. The total reflux time within 24 hours was 75 minutes. The DeMeester score was 38.3. Results of esophageal pressure measurement showed that the esophageal contraction morphology was normal, but the anastomotic opening was not well relaxed. The rest of 9 cases had no complication such as reflux esophagitis.Conclusion:Biological muscle flap applied in the laparoscopic radical proximal gastrectomy with esophagogastric anastomosis is safe and feasible, with satisfied short-term efficacy.

Objective:To explore the effects of different concentrations of ropivacaine ultrasound-guided transverse abdominis plane block on postoperative pain and stress response in patients undergoing laparoscopic sleeve gastrectomy.Methods:A prospective study was conducted on 120 obese patients who underwent laparoscopic sleeve gastrectomy at the Puren Hospital Affiliated to Wuhan University of Science and Technology from July 2020 to July 2022. According to the random number table method, all patients were divided into a control group, a low concentration group, and a high concentration group, with 40 cases in each group. All three groups underwent ultrasound-guided transverse abdominis plane block after general anesthesia induction. The control group was injected with physiological saline, while the low concentration group and high concentration group were injected with 0.25% and 0.50% ropivacaine, respectively. Stress response indicators before and after surgery in three groups [adrenaline (E), cortisol (Cor), free thyroxine (FT4), and C-reactive protein (CRP)], hemodynamic indicators [mean arterial pressure (MAP) and heart rate (HR)], glucose and lipid metabolism indicators [fasting blood glucose (FBG), 2-hour postprandial blood glucose (2-hour PBG), glycated hemoglobin (HbA 1c), total cholesterol (TC), and triglycerides (TG)] and Visual Analog Scale (VAS) score were compared before and after surgery. Results:On the 1st day after surgery, the levels of E, Cor, FT4, CRP, FBG, 2-hour PBG, HbA 1c, TC, and TG in the high concentration group were lower than those in the control group and low concentration group (all P<0.05); 15 minutes after anesthesia and 2 hours after surgery, the MAP and HR of the high concentration group were higher than those of the control group and the low concentration group (all P<0.05); At 6, 12, and 24 hours after surgery, the VAS score of the high concentration group was lower than that of the control group and the low concentration group (all P<0.05); There was no statistically significant difference in the incidence of airway reactions during anesthesia induction among the three groups ( P>0.05). Conclusions:In laparoscopic sleeve gastrectomy, administering 0.50% concentration of ropivacaine ultrasound-guided plane block of the transverse abdominis muscle has a strong postoperative analgesic effect, which can improve E, Cor, FT4, and CRP levels, and is worthy of clinical application.
