ABSTRACT

OBJECTIVE: The present study aims to investigate the relationship between bile reflux (BR) and diameter of the common bile duct (CBD) in patients after cholecystectomy. MATERIALS AND METHODS: In our case series analysis, according to the endoscopy results, the patients who underwent cholecystectomy were divided into two groups as those with BR and those non-BR. Age, sex, CBD diameter measured on ultrasonography, computed tomography, magnetic resonance cholangiopancreatography, and endoscopic biopsy results of the patients were statistically analyzed. RESULTS: In a total of 188 patients included in the study, BR was detected in 93 patients, it was not observed in 95 patients. The CBD diameter of the patients was observed to be 7 mm or less in 70.9% (n = 66) in the BR group, and 23% (n = 22) in the non-BR group. The statistical analysis revealed that while there was a significant difference between the two groups in terms of CBD diameter and intestinal metaplasia, the results were similar in both groups in terms of inflammation, activity, atrophy, and Helicobacter pylori. CONCLUSION: We believe that CBD diameter may be a predictive factor in the detection of BR after cholecystectomy.


OBJETIVO: Investigar la relación entre el reflujo biliar y el diámetro del colédoco después de la colecistectomía. MÉTODO: Estudio retrospectivo en el que, de acuerdo con los resultados de la endoscopia, los pacientes que se sometieron a colecistectomía se dividieron en dos grupos: con reflujo biliar y sin reflujo biliar. Se analizaron estadísticamente la edad, el sexo, el diámetro del conducto biliar común medido por ultrasonografía, tomografía computarizada y colangiopancreatografía por resonancia magnética, y los resultados de la biopsia endoscópica. RESULTADOS: En un total de 188 pacientes incluidos en el estudio, se detectó reflujo biliar en 93 pacientes y no se observó en 95 pacientes. Se vio que el diámetro del conducto biliar común de los pacientes era de 7 mm o menos en el 70.9% (n = 66) del grupo con reflujo biliar y en el 23% (n = 22) del grupo sin reflujo biliar. El análisis estadístico reveló que, si bien hubo una diferencia significativa entre los dos grupos en términos de diámetro del conducto biliar común y metaplasia intestinal, los resultados fueron similares en ambos grupos en términos de inflamación, actividad, atrofia y presencia de Helicobacter pylori. CONCLUSIONES: Creemos que el diámetro del colédoco puede ser un factor predictivo en la detección de reflujo biliar después de la colecistectomía.

ABSTRACT

BACKGROUND: There is much debate over the occurrence of biliary reflux to the gastric pouch after one anastomosis gastric bypass (OAGB) and its potential risks. OBJECTIVE: To assess endoscopic and histopathological findings following a standardized protocol of biopsy collection two years after OAGB. METHODS: A historical cohort study was conducted, based on a prospectively collected database, which involved 39 participants who underwent OAGB. Participants underwent clinical evaluation and esophagogastroduodenoscopy at the time of surgery and 24 months afterward. Post-operatively, biopsy specimens in esophagogastric junction, pouch, and anastomosis were systematically collected. RESULTS: 92.3% of the participants were female and the mean age was 37 ± 8.5 years. The mean body mass index (BMI) significantly decreased from 37.6 ± 5.7 kg/m2 to 27 ± 4.1 kg/m2 after 2 years (p < 0.001). The mean %TWL was 27.2 ± 10.5%. The prevalence of non-erosive gastritis significantly increased from 25.6 to 51.3% (p = 0.02). Erosive gastritis significantly decreased from 28.2 to 10.3% (p = 0.04). Four cases of marginal ulcers were identified (10.3%). The commonest histopathological finding was mild inflammation in 74.3% (esophagogastric junction), 58.9% (pouch), and 71.8% (anastomosis). There was one case of focal intestinal metaplasia in each site of interest and no cases of dysplasia or severe inflammation. CONCLUSIONS: Using a standardized protocol of post-operative biopsy collection, low rates of severe endoscopic and histopathological abnormalities were observed two years after OAGB. Nevertheless, as most patients have histologically proven inflammation, bile in the gastric pouch, and endoscopic gastritis, long-term surveillance is essential because of the uncertain risk of these abnormalities.

ABSTRACT

ABSTRACT Background : In recent years, a surgical technique known as single-anastomosis gastric bypass or mini-gastric bypass has been developed. Its frequency of performance has increased considerably in the current decade. Aim : To describe the mini-gastric bypass technique, its implementation and preliminary results in a university hospital. Methods : This is an ongoing prospective trial to evaluate the long-term effects of mini-gastric bypass. The main features of the operation were: a gastric pouch with about 15-18 cm (50-150 ml) with a gastroenteric anastomosis in the pre-colic isoperistaltic loop 200 cm from the duodenojejunal angle (biliopancreatic loop). Results : Seventeen individuals have undergone surgery. No procedure needed to be converted to open approach. The overall 30-day morbidity was 5.9% (one individual had intestinal obstruction caused by adhesions). There was no mortality. Conclusion : Mini-gastric bypass is a feasible and safe bariatric surgical procedure.


RESUMO Racional : Nos últimos anos foi desenvolvida técnica cirúrgica conhecida como derivação gástrica com anastomose única ou mini-bypass gástrico. A frequência com que este procedimento vem sendo realizado aumentou consideravelmente na última década. Objetivo : Descrever a técnica do procedimento, sua implementação e resultados preliminares em um hospital universitário. Métodos : Estudo prospectivo em andamento para avaliar os efeitos em longo prazo do mini-bypass gástrico. As principais características do mini-bypass gástrico laparoscópico foram: uma bolsa gástrica com cerca de 15-18 cm (50-150 ml) com anastomose gastroentérica em alça isoperistáltica pré-cólica a 200 cm do ângulo duodenojejunal (alça biliopancreática). Resultados : Foram operados 17 pacientes. Nenhum procedimento necessitou conversão para laparotomia. A morbidade global em 30 dias foi de 5,9% (um caso de obstrução por brida). Não houve mortalidade. Conclusão : O mini-bypass gástrico é procedimento cirúrgico bariátrico factível e seguro.

ABSTRACT

ABSTRACT Introduction: Single anastomosis gastric bypass (one anastomosis gastric bypass or mini-gastric bypass) has been presented as an option of surgical treatment for obese patients in order to reduce operation time and avoiding eventual postoperative complications after Roux-en-Y gastric bypass.The main late complication could be related to bile reflux. Aim: To report the experiences published after Billroth II anastomosis and its adverse effects regarding symptoms and damage on the gastric and esophageal mucosa . Method: For data recollection Medline, Pubmed, Scielo and Cochrane database were accessed, giving a total of 168 papers being chosen 57 of them. Results: According the reported results during open era surgery for peptic disease and more recent results for gastric cancer surgery, bile reflux and its consequences are more frequent after Billroth II operation compared to Roux-en-Y gastrojejunal anastomosis. Conclusion: These findings must be considered for the indication of bariatric surgery.


RESUMO Introdução: Bypass com anastomose única ou mini-bypass gástrico foi apresentado como oopção de tratamento cirúrgico para pacientes obesos, a fim de reduzir o tempo da operação e evitar complicações pós-operatórias após bypass gástrico Y-de-Roux. A principal complicação tardia pode estar relacionada ao refluxo biliar. Objetivo: Relatar as experiências publicadas após a anastomose Billroth II e seus efeitos adversos em relação aos sintomas e danos sobre a mucosa gástrica e esofágica. Método: A coleta de dados foi baseada na busca nas bases Medline, Pubmed, Scielo e Cochrane. Um total de 168 artigos foram revisados, tendo sido escolhidos 57 deles. Resultados: De acordo com os resultados relatados durante a operação da era aberta para doença péptica e resultados mais recentes para o tratamento cirúrgico do câncer gástrico, o refluxo biliar e suas consequências são mais frequentes após o Billroth II em comparação com a anastomose gastrojejunal em Y-de-Roux. Conclusão: Esses achados devem ser considerados para a indicação de cirurgia bariátrica.

ABSTRACT

La gastropatía reactiva (GR) es producida principalmente por antiinflamatorios no esteroideos (AINEs) y reflujo biliar; puede presentarse aisladamente o coexistir con otros tipos de gastritis crónica (GC). Se revisaron 5.079 informes de estudios histopatológicos de biopsias gástricas de 4.254 pacientes, 825 en seguimiento con 2 a 7 estudios. La GR correspondió a 12,8% de los diagnósticos, las GC no atrófica (GCNA) y atrófica multifocal (GCAMF) correspondieron a 63,4% y 27,3% respectivamente. La infección por Helicobacter pylori se presentó en 61,6% de casos con GCNA, 51,5% con GCAMF, 18,5% con GR (p < 0.0001); en casos con coexistencia de GR+GCNA fue 43,9% y de 40,7% para GCAMF+GR. En pacientes en seguimiento aumentaron los diagnósticos de GR: 2 estudios con 22,2%, 3 estudios con 26,7% y 4-7 estudios con 28,8%; los hallazgos histológicos de GR en estos casos posiblemente son residuales, luego de la desaparición de los infiltrados inflamatorios por el tratamiento.


Reactive gastropathy (RG) is primarily produced by non-steroid antiinflammatory drugs (NSAIDs) and bile reflux. It can occur alone or coexist with other types of chronic gastritis (CG). 5,079 histopathological reports of gastric biopsies from 4,254 patients were reviewed: 825 of them had 2 to 7 follow-up studies. 12.8% of these patients were diagnosed with GR while 63.4% were diagnosed with chronic non-atrophic gastritis (CNAG) and 27.3% were diagnosed with chronic multifocal atrophic gastritis (CMAG). Helicobacter pylori infections were found in 61.6% of the cases with CNAG, 51.5% with CMAG, and in 18.5% of cases with GR only (p <0.0001). Among patients suffering from both RG and CNAG 43.9% had H. pylori infections. 40.7% of those suffering from both CMAG and RG were infected with H. pylori. During monitoring of patients RG diagnoses increased to 22.2% in the second study, 26.7% in the third study, and 28.8% in the fourth through seventh studies. Histological findings of RG in these cases are probably residual following disappearance of inflammatory infiltrates due to treatment.
