BILE DUCT INJURY REPAIR IN A PATIENT WITH SITUS INVERSUS TOTALIS.

BACKGROUND: Bile duct injury (BDI) causes significant sequelae for the patient in terms of morbidity, mortality, and long-term quality of life, and should be managed in centers with expertise. Anatomical variants may contribute to a higher risk of BDI during cholecystectomy. AIMS: To report a case of bile duct injury in a patient with situs inversus totalis. METHODS: A 42-year-old female patient with a previous history of situs inversus totalis and a BDI was initially operated on simultaneously to the lesion ten years ago by a non-specialized surgeon. She was referred to a specialized center due to recurrent episodes of cholangitis and a cholestatic laboratory pattern. Cholangioresonance revealed a severe anastomotic stricture. Due to her young age and recurrent cholangitis, she was submitted to a redo hepaticojejunostomy with the Hepp-Couinaud technique. To the best of our knowledge, this is the first report of BDI repair in a patient with situs inversus totalis. RESULTS: The previous hepaticojejunostomy was undone and remade with the Hepp-Couinaud technique high in the hilar plate with a wide opening in the hepatic confluence of the bile ducts towards the left hepatic duct. The previous Roux limb was maintained. Postoperative recovery was uneventful, the drain was removed on the seventh post-operative day, and the patient is now asymptomatic, with normal bilirubin and canalicular enzymes, and no further episodes of cholestasis or cholangitis. CONCLUSIONS: Anatomical variants may increase the difficulty of both cholecystectomy and BDI repair. BDI repair should be performed in a specialized center by formal hepato-pancreato-biliary surgeons to assure a safe perioperative management and a good long-term outcome.

RESUMO RACIONAL: As lesões de via biliar (LVB) impõem sequelas significativas ao paciente em termos de morbidade, mortalidade e qualidade de vida a longo prazo, devendo ser manejadas em centros especializados. Variantes anatômicas podem contribuir para um maior risco de LVB durante colecistectomia. OBJETIVOS: Relatar paciente com lesão de via biliar associado a situs inversus totalis. MÉTODOS: Paciente do sexo feminino, 42 anos, com histórico prévio de situs inversus totalis e LVB inicialmente reparada simultaneamente à lesão, há 10 anos, por um cirurgião não especializado. Ela foi encaminhada a um centro especializado devido a episódios recorrentes de colangite e um padrão laboratorial colestático. Colangiressonância revelou uma grave estenose anastomótica. Devido à sua idade jovem e colangites recorrentes, foi submetida a uma revisão cirúrgica da hepaticojejunostomia com técnica de Hepp-Couinaud. Até onde sabemos, este é o primeiro relato de reparo de LVB em um paciente com situs inversus totalis. RESULTADOS: A hepaticojejunostomia realizado prèviamente foi desfeita e refeita empregando a técnica de Hepp-Couinaud, alta na placa hilar, com uma ampla abertura na confluência dos ductos biliares em direção ao ducto hepático esquerdo. A alça de roux anterior foi mantida. A recuperação pós-operatória transcorreu sem intercorrências, o dreno foi removido no sétimo dia pós-operatório, e a paciente está agora assintomática, com bilirrubina e enzimas canalículares normais, e sem mais episódios de colestase ou colangite. CONCLUSÕES: Variantes anatômicas podem aumentar a dificuldade tanto da colecistectomia quanto do reparo de LVB, o qual deve ser realizado em um centro especializado por cirurgiões hepatobiliares para garantir um manejo perioperatório seguro e um bom resultado a longo prazo.

A case report of esophageal leiomyoma in Alport's syndrome treated with robotic-assisted distal myotomy: A surgical technique to avoid esophagectomy.

INTRODUCTION: Alport's syndrome is the most common hereditary nephropathy, characterized by progressive renal failure, sensorineural deafness, and ocular abnormalities. It may rarely coexist with diffuse leiomyomatosis of the digestive tract, respiratory tract, or female genitalia, and in this setting, it is called Alport-leiomyomatosis syndrome. The leiomyomas most commonly affect the esophagus, and the symptoms have early onset. Treatment is usually esophagectomy. CASE PRESENTATION: We report the case of an 8 years-old girl in which we performed a novel strategy of an esophagus-sparing approach with a robotic-assisted myotomy. This conservative approach has never been described in the literature to our knowledge. DISCUSSION: The underpinning rationale was to resolve the patient's symptoms with partial resection of the benign tumor, avoiding an esophagectomy. Although it is likely related to a higher relapsing rate, it is more tolerable by an 8 years-old patient, and was highly effective in resolving her symptoms. CONCLUSION: The video of a successful minimally invasive conservative approach to esophageal leiomyomatosis is presented.

Oxidative status in colostrum and mature breast milk related to gestational age and fetal growth.

INTRODUCTION: The effect of gestational age and fetal growth on the oxidant/antioxidant status of breast milk is poorly understood. OBJECTIVE: To evaluate the oxidative stress biomarkers in colostrum and mature milk according to gestational age and fetal growth. METHOD: A longitudinal study with mothers of premature and term infants, born in a tertiary referral hospital between 2014-2018. Inclusion criteria: postpartum women with a singleton pregnancy, who intended to exclusively breastfeed. Exclusion criteria: maternal diabetes, use of medication, drug addiction, congenital infection or malformation, mastitis, and failure to collect colostrum. Four groups were formed according to gestational age and birth weight (appropriate and small): Preterm small (n = 37), Preterm appropriate (n = 99), Full-term small (n = 65), and Full-term appropriate (control, n = 69). The colostrum samples were collected between 24-72 h and the mature milk was sampled in the 4th week of lactation for malondialdehyde (biomarker for lipid peroxidation) and Glutathione peroxidase, Catalase, and Superoxide dismutase measurements. The data were compared among groups using the Chi-square test or Fisher's exact test, one-way analysis of variance followed by Wald's Distribution test and repeated measures analysis of variance. RESULTS: We found a lower malondialdehyde level in colostrum in preterm groups and term small for gestational age, and the antioxidant enzymes Superoxide dismutase and Catalase activities were higher for preterm compared to term groups. The malondialdehyde levels differed in mature milk samples (Full-term small > Full-term appropriate > Preterm small > Preterm appropriate). The malondialdehyde levels increased during lactation in all groups except Preterm appropriate, and the levels of Catalase decreased in preterm groups. CONCLUSION: The oxidative status in breast milk is influenced by gestational age and fetal growth, which increased antioxidant defense for preterm infants and decreased oxidative stimuli for small for gestational age infants. These findings contribute to encouraging breastfeeding for newborns.

PANCREATIC SOLID-PSEUDOPAPILLARY NEOPLASM IN PATIENTS WITH FAMILIAL ADENOMATOUS POLYPOSIS.

BACKGROUND: Solid pseudopapillary neoplasm of the pancreas is an uncommon pancreatic tumor, which is more frequent in young adult women. Familial adenomatous polyposis is a genetic condition associated with colorectal cancer that also increases the risk of developing other tumors as well. AIM: The aim of this study was to discuss the association of familial adenomatous polyposis with solid pseudopapillary neoplasm of the pancreas, which is very rare. METHODS: We report two cases of patients with familial adenomatous polyposis who developed solid pseudopapillary neoplasm of the pancreas of the pancreas and were submitted to laparoscopic pancreatic resections with splenic preservation (one male and one female). RESULTS: ß-catenin and Wnt signaling pathways have been found to play an important role in the tumorigenesis of solid pseudopapillary neoplasm of the pancreas, and their constitutive activation due to adenomatous polyposis coli gene inactivation in familial adenomatous polyposis may explain the relationship between familial adenomatous polyposis and solid pseudopapillary neoplasm of the pancreas. CONCLUSION: Colonic resection must be prioritized, and a minimally invasive approach is preferred to minimize the risk of developing desmoid tumor. Pancreatic resection usually does not require extensive lymphadenectomy for solid pseudopapillary neoplasm of the pancreas, and splenic preservation is feasible.

Molecular Profile of Intrahepatic Cholangiocarcinoma.

Intrahepatic cholangiocarcinoma (ICC) is a relatively uncommon but highly aggressive primary liver cancer that originates within the liver. The aim of this study is to review the molecular profile of intrahepatic cholangiocarcinoma and its implications for prognostication and decision-making. This comprehensive characterization of ICC tumors sheds light on the disease's underlying biology and offers a foundation for more personalized treatment strategies. This is a narrative review of the prognostic and therapeutic role of the molecular profile of ICC. Knowing the molecular profile of tumors helps determine prognosis and support certain target therapies. The molecular panel in ICC helps to select patients for specific therapies, predict treatment responses, and monitor treatment responses. Precision medicine in ICC can promote improvement in prognosis and reduce unnecessary toxicity and might have a significant role in the management of ICC in the following years. The main mutations in ICC are in tumor protein p53 (TP53), Kirsten rat sarcoma virus (KRAS), isocitrate dehydrogenase 1 (IDH1), and AT-rich interactive domain-containing protein 1A (ARID1A). The rate of mutations varies significantly for each population. Targeting TP53 and KRAS is challenging due to the natural characteristics of these genes. Different stages of clinical studies have shown encouraging results with inhibitors of mutated IDH1 and target therapy for ARID1A downstream effectors. Fibroblast growth factor receptor 2 (FGFR2) fusions are an important target in patients with ICC. Immune checkpoint blockade can be applied to a small percentage of ICC patients. Molecular profiling in ICC represents a groundbreaking approach to understanding and managing this complex liver cancer. As our comprehension of ICC's molecular intricacies continues to expand, so does the potential for offering patients more precise and effective treatments. The integration of molecular profiling into clinical practice signifies the dawn of a new era in ICC care, emphasizing personalized medicine in the ongoing battle against this malignancy.

Preoperative inflammatory markers as prognostic predictors after hepatocellular carcinoma resection: data from a western referral center.

BACKGROUND: Recent studies from eastern centers have demonstrate an association between inflammatory response and long-term outcomes after hepatocellular carcinoma (HCC) resection. However, the prognostic impact of inflammatory markers in western patients, with distinct tumor and epidemiologic features, is still unknown. AIM: To evaluate the prognostic impact of preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR), as well as their impact according to tumor size (< 5 cm, 5-10 cm, > 10 cm) in patients undergoing HCC resection with curative intent. METHODS: Optimal cut-off values for NLR, PLR, and MLR were determined by plotting the receiver operator curves. Overall survival (OS) and disease-free survival (DFS) curves were calculated using the Kaplan-Meier method and compared using the log-rank test. The Cox method was used to identify independent predictors of OS and DFS. RESULTS: In total, 161 consecutive adult patients were included. A high NLR (> 1.715) was associated with worse OS (P = 0.018). High NLR (> 2.475; P = 0.047) and PLR (> 100.25; P = 0.028) were predictors of short DFS. In HCC < 5 cm, MLR (> 1.715) was associated with worse OS (P = 0.047). In the multivariate analysis, high PLR was an independent predictor of worse DFS [hazard ratio (HR) 3.029; 95%CI 1.499-6.121; P = 0.002]. CONCLUSION: Inflammatory markers are useful tools to predict long-term outcomes after liver resection in western patients, high NLR was able to stratify subgroups of patients with short OS and DFS, an increased PLR was an independent predictor of short DFS, while high MLR was associated with short OS in patients with early HCC.

Platelet-albumin (PAL) score as a predictor of perioperative outcomes and survival in patients with hepatocellular carcinoma undergoing liver resection in a Western center.

BACKGROUND AND OBJECTIVES: Preoperative selection of patients with hepatocellular carcinoma (HCC) who will benefit from resection is highly advisable. The Platelet-Albumin (PAL) score was developed as a predictor of survival and morbidity following HCC resection. However, this has never been tested in western populations. METHODS: The impact of PAL score on perioperative outcomes and survival was evaluated and compared to Child-Pugh, Model for End-Stage Liver Disease (MELD), and albumin-bilirubin (ALBI) scores in patients who underwent HCC resection. RESULTS: A total of 182 patients were included. Postoperative morbidity was higher in patients with PAL grade II-III (P = 0.039), ALBI grade II-III (P = 0.028), and MELD >10 (P = 0.042). Post-hepatectomy liver failure (PHLF) occurred in 36 patients (19.8%) and was significantly higher in the PAL II-III and ALBI score II-III subgroup (P = 0.001). The PAL II-III group was the only one associated with higher perioperative mortality (OR 3.3, P = 0.036). The PAL score was an independent prognostic factor for overall survival in multivariate analysis (P = 0.018) and was the only one with the areas under the curve in ROC analysis significantly different for morbidity, PHLF, and mortality. CONCLUSIONS: The PAL score predicts postoperative complications, mortality, PHLF, and survival following liver resection for HCC in western patients.

Pancreatic solid-pseudopapillary neoplasm in patients with familial adenomatous polyposis / Neoplasia sólida pseudopapilífera pancreática em pacientes com polipose adenomatosa familiar

RESUMO RACIONAL: A neoplasia sólida pseudopapilífera do pâncreas é um tumor pancreático incomum, mais frequente em mulheres jovens. A polipose adenomatosa familiar, por sua vez, é uma condição genética associada a câncer colorretal e que também aumenta o risco de desenvolvimento de outros tumores. OBJETIVOS: Discutir a associação entre polipose adenomatosa familiar e neoplasia sólida pseudopapilífera, que é bastante rara. MÉTODOS: Reportamos dois casos de pacientes com polipose adenomatosa familiar, um homem e uma mulher, que desenvolveram neoplasia sólida pseudopapilífera do pâncreas e foram submetidos a ressecção laparoscópica com preservação esplênica. RESULTADOS: As vias de sinalização da ß-catenina e Wnt tem um papel importante na tumorigênese da neoplasia sólida pseudopapilífera, e sua ativação constitutiva devido a inativação do gene adenomatous polyposis coli na polipose adenomatosa familiar pode explicar a relação entre polipose adenomatosa familiar e neoplasia sólida pseudopapilífera. CONCLUSÕES: A ressecção do cólon deve ser priorizada, com preferência pela abordagem minimamente invasiva para minimizar o risco de desenvolvimento de tumor desmoide. A ressecção pancreática geralmente não requer linfadenectomia extensa para neoplasia sólida pseudopapilífera, portanto, a preservação esplênica é factível.

Anorectal Mucosal Melanoma: A Case Report and Literature Review.

BACKGROUND Anorectal mucosal melanoma (AMM) is a rare and aggressive neoplasm, with a 5-year survival rate of 10%. Due to its rarity and nonspecific symptoms, the diagnosis is often made late. Surgical resection remains the criterion standard for treatment of anorectal melanoma. CASE REPORT We present the case of an 81-year-old woman presenting with hematochezia, anal secretion, tenesmus, difficulty in defecation, and perianal pain. On physical examination, there was a prolapse of a 5-cm melanocytic nodule in the anal canal, hard on palpation. Biopsy confirmed anorectal melanoma. Staging revealed anal and metastatic disease, with adrenal, lymphatic, and hepatic involvement. As the patient continued to have bleeding, severe pain, and difficulty in defecation, she was submitted to a wide local excision. At 5-month follow-up, the anal lesion had relapsed, and the patient died 10 months after the procedure. CONCLUSIONS AMM is a rare and extremely aggressive tumor. Symptoms are nonspecific but early diagnosis should be pursued to allow curative treatment. Surgical resection with free margins is the goal of surgical treatment. New therapies are being studied, including immunotherapy, which can improve the dismal prognosis of this rare disease.

Non-operative management of blunt splenic trauma: evolution, results and controversies.

The spleen is one of the most frequently affected organs in blunt abdominal trauma. Since Upadhyaya, the treatment of splenic trauma has undergone important changes. Currently, the consensus is that every splenic trauma presenting with hemodynamic stability should be initially treated nonoperatively, provided that the hospital has adequate structure and the patient does not present other conditions that indicate abdominal exploration. However, several topics regarding the nonoperative management (NOM) of splenic trauma are still controversial. Splenic angioembolization is a very useful tool for NOM, but there is no consensus on its precise indications. There is no definition in the literature as to how NOM should be conducted, neither about the periodicity of hematimetric control, the transfusion threshold that defines NOM failure, when to start venous thromboembolism prophylaxis, the need for control imaging, the duration of bed rest, and when it is safe to discharge the patient. The aim of this review is to make a critical analysis of the most recent literature on this topic, exposing the state of the art in the NOM of splenic trauma.

Is it Safe to Perform Elective Colorectal Surgical Procedures during the COVID-19 Pandemic? A Single Institution Experience with 103 Patients.

OBJECTIVES: Since the outbreak of the novel coronavirus disease 2019 (COVID-19), all health services worldwide underwent profound changes, leading to the suspension of many elective surgeries. This study aimed to evaluate the safety of elective colorectal surgery during the pandemic. METHODS: This was a retrospective, cross-sectional, single-center study. Patients who underwent elective colorectal surgery during the COVID-19 pandemic between March 10 and September 9, 2020, were included. Patient data on sex, age, diagnosis, types of procedures, hospital stay, mortality, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) preoperative screening tests were recorded. RESULTS: A total of 103 colorectal surgical procedures were planned, and 99 were performed. Four surgeries were postponed due to positive preoperative screening for SARS-CoV-2. Surgical procedures were performed for colorectal cancer (n=90) and inflammatory bowel disease (n=9). Laparoscopy was the approach of choice for 43 patients (43.4%), 53 (53.5%) procedures were open, and 3 (3%) procedures were robotic. Five patients developed COVID-19 in the postoperative period, and three of them died in the intensive care unit (n=3/5, 60% mortality). Two other patients died due to surgical complications unrelated to COVID-19 (n=2/94, 2.1% mortality) (p<0.01). Hospital stay was longer in patients with SARS-CoV-2 infection than in those without (38.4 versushttps://doi.org/10.3 days, respectively, p<0.01). Of the 99 patients who received surgical care during the pandemic, 94 were safely discharged (95%). CONCLUSION: Our study demonstrated that elective colorectal surgical procedures may be safely performed during the pandemic; however, preoperative testing should be performed to reduce in-hospital infection rates, since the mortality rate due to SARS-CoV-2 in this setting is particularly high.

RESUMO O baço é um dos órgãos mais frequentemente afetados no trauma abdominal contuso. Desde os trabalhos de Upadhyaya, o tratamento do trauma esplênico vem sofrendo importantes modificações. Atualmente, é consenso que todo trauma esplênico que se apresenta com estabilidade hemodinâmica pode ser tratado inicialmente de forma não operatória, desde que o serviço possua estrutura adequada e o paciente não apresente outras condições que indiquem exploração da cavidade abdominal. Entretanto, vários tópicos permanecem controversos no que diz respeito ao tratamento não operatório (TNO) do trauma esplênico. A angioembolização esplênica é uma ferramenta de grande auxílio no TNO, porém não há consenso sobre suas indicações precisas. Não há uma definição na literatura a respeito da forma como o TNO deve ser conduzido, tampouco a respeito da periodicidade do controle hematimétrico, do limiar de transfusão que define falha do TNO, de quando iniciar a profilaxia contra tromboembolismo venoso, da necessidade de exames de imagem de controle, do período de repouso no leito, e de quando é seguro indicar alta hospitalar. O objetivo desta revisão é analisar de forma crítica a literatura a respeito desse tema, expondo o estado da arte no TNO do trauma esplênico.
