The overall rate of postoperative complications did not differ significantly between adults (7%) and older adults (11%) (p>0.05) and no significant differences were observed in the rates of minor (Clavien-Dindo grade II; 3-5% vs. 6-12%; p>0.05) and severe complications (Clavien-Dindo ≥ IIIa; 3-5% vs. 4-8%; p>0.05). Conclusions. No statistically differences were found in short-term outcomes between adult and older patients with locally advanced gastric cancer treated with laparoscopic gastrectomy. This technique is safe in the elderly.

Complicaciones de la laringectomía total: experiencia de 7 años en un hospital universitario de Paraguay / Complications of total laryngectomy: a 7-year experience in a university hospital in Paraguay

Introducción: El cáncer de laringe es la neoplasia maligna más común de las vías aerodigestivas superiores. La laringectomía total es el tratamiento de elección en casos avanzados, pero se asocia a una alta tasa de complicaciones. Objetivos: Conocer la prevalencia de las complicaciones posquirúrgicas de la laringectomía total y los factores asociados en pacientes con cáncer de laringe. Materiales y métodos: Estudio observacional, descriptivo, retrospectivo, de corte transversal, revisando el comportamiento de la laringectomía total y sus principales complicaciones en la Cátedra y Servicio de Otorrinolaringología del Hospital de Clínicas de la Facultad de Ciencias Médicas de la Universidad Nacional de Asunción, Paraguay, de 2015 a 2022. Se incluyeron pacientes mayores de 18 años, de ambos sexos, postoperados de laringectomía total, con diagnóstico anatomopatológico de neoplasia de laringe. Se excluyeron pacientes no operados, con fichas incompletas o que abandonaron el tratamiento. Se analizaron variables demográficas, clínicas, quirúrgicas y anatomopatológicas. Resultados: Se incluyeron 10 pacientes, todos varones, con edad media de 56,3 ± 10,2 años. El 90% presentaba hábitos tóxicos. La complicación más frecuente fue la fístula faringocutánea (70%), seguida por infección del sitio quirúrgico (10%) y sangrado posoperatorio (10%). El 71,4% de las fístulas se resolvieron con medidas conservadoras. El 30% tenía afectación supraglótica y el 57,1% de los que presentaron complicaciones recibieron radioterapia previa. Conclusión: Las complicaciones de la laringectomía total son frecuentes, principalmente la fístula faringocutánea.

Introduction: Laryngeal cancer is the most common malignant neoplasm of the upper aerodigestive tract. Total laryngectomy is the treatment of choice in advanced cases, but it is associated with a high rate of complications. Objectives: To determine the prevalence of postoperative complications of total laryngectomy and associated factors in patients with laryngeal cancer. Materials and methods: Observational, descriptive, retrospective, cross-sectional study, reviewing the behavior of total laryngectomy and its main complications in the Department of Otorhinolaryngology of the Hospital de Clínicas, Faculty of Medical Sciences, National University of Asunción, Paraguay, from 2015 to 2022. Patients over 18 years of age, of both sexes, who underwent total laryngectomy, with anatomopathological diagnosis of laryngeal neoplasm were included. Non-operated patients, those with incomplete records or who abandoned treatment were excluded. Demographic, clinical, surgical and anatomopathological variables were analyzed. Results: Ten patients were included, all male, with a mean age of 56.3 ± 10.2 years. Ninety percent had toxic habits. The most frequent complication was pharyngocutaneous fistula (70%), followed by surgical site infection (10%) and postoperative bleeding (10%). Conservative measures resolved 71.4% of the fistulas. Thirty percent had supraglottic involvement and 57.1% of those who presented complications received previous radiotherapy. Conclusion: Complications of total laryngectomy are frequent, mainly pharyngocutaneous fistula. Supraglottic involvement and previous radiotherapy were associated with a higher rate of complications. Prospective studies with larger samples are required to confirm these findings.

Fístula pancreática: una complicación temida. Experiencia en una unidad de cirugía hepatobiliopancreática de cuarto nivel / Pancreatic fistula: A feared complication. Experience in a fourth level hepatobiliopancreatic surgery unit

Introducción. La fístula pancreática postoperatoria es una de las complicaciones más importantes en la cirugía hepatobiliopancreática. Su diagnóstico se hace mediante la presencia de un nivel de amilasa en el líquido de drenaje al menos tres veces por encima del valor de la amilasa en suero a partir del tercer día postoperatorio. El objetivo de este estudio fue caracterizar los pacientes con fístula pancreática postoperatoria en nuestra institución, evaluando la importancia de la detección temprana y el establecimiento de un manejo oportuno. Métodos. Estudio descriptivo, retrospectivo, que incluyó los pacientes sometidos a pancreatoduodenectomía, con diagnóstico de fístula pancreática postoperatoria como complicación de cirugía hepatobiliopancreática, en el Hospital Internacional de Colombia, en Piedecuesta, entre enero del 2017 y diciembre de 2020. Se excluyeron los pacientes con otro tipo procedimiento quirúrgico y aquellos que decidieron no participar en el estudio. Resultados. Se evaluaron 69 pacientes, con un predominio del sexo femenino (n=38; 55,1 %) y mediana de la edad de 57 años. El 33,3 % (n=24) de los pacientes intervenidos desarrollaron fístula pancreática postoperatoria, siendo el 23,2 % fuga bioquímica, grado B 8,7 % y grado C 2,9 %, para quienes se indicaron manejo expectante, control ecográfico y reintervención, respectivamente. Fallecieron 5 pacientes (7,2 %). Conclusiones. La fístula pancreáticapostoperatoria es una complicación para tener en cuenta en todos los pacientes sometidos a pancreatoduodenectomía. Existen estrategias que pueden permitir disminuir la incidencia de esta complicación, con el fin de mejorar el desenlace, el pronóstico y la morbilidad posquirúrgica.

Introduction. Postoperative pancreatic fistula is one of the most important complications in hepatobiliopancreatic surgery. Its diagnosis is made by the presence of an amylase level in the drainage fluid at least three times above the serum amylase value from the third postoperative day. The objective of this study was to characterize patients with postoperative pancreatic fistula at our institution, evaluating the importance of early detection and to establish a timely management. Methods. Descriptive, retrospective study that included patients who underwent pancreatoduodenectomy with a diagnosis of postoperative pancreatic fistula as a complication of hepatobiliopancreatic surgery at the Hospital Internacional Colombia, between January 2017 and December 2020. Patients with another type of procedure performed by this specialty and those who did not decide to participate in the study were excluded. Results. A total of 69 patients were included, the median age was 57 years with a predominance of females (n=38; 55.1%). 33.3% (n=24) of the operated patients developed postoperative pancreatic fistula, with 23.2% having a biochemical leak, grade B in 8.7% and grade C in 2.9%, for whom expectant management, ultrasound control and reintervention were indicated, respectively. Five patients died (7.2%). Conclusions. Pancreatic fistula is a complication to take into account in all patients undergoing pancreatoduodenectomy. There are strategies that can reduce the incidence of this complication and thus improve not only the outcome but also the prognosis and postoperative morbidity.

Assessment of risk factors for leakage after repair of perforated peptic ulcer with omental patch. Retrospective study / Evaluación de factores de riesgo de fuga después de la reparación de una úlcera péptica perforada con parche de epiplón. Estudio retrospectivo

Introduction. Perforated peptic ulcer remains one of the critical abdominal conditions that requires early surgical intervention. Leakage after omental patch repair represents one of the devastating complications that increase morbidity and mortality. Our study aimed to assess risk factors and early predictors for incidence of leakage. Methods. Retrospective analysis of data of the patients who underwent omental patch repair for perforated peptic ulcer in the period between January 2019 and January 2022 in Mansoura University Hospital, Egypt. Pre, intra and postoperative variables were collected and statistically analyzed. Incriminated risk factors for leakage incidence were analyzed using univariate and multivariate analysis. Results. This study included 123 patients who met inclusion criteria. Leakage was detected in seven (5.7%) patients. Although associated comorbidities (p=0.01), postoperative intensive care unit admission (p=0.03), and postoperative hypotension (p=0.02) were significant risk factors in univariate analysis, septic shock (p=0.001), delayed intervention (p=0.04), preoperative hypoalbuminemia (p=0.017), and perforation size >5mm (p= 0.04) were found as independent risk factors for leakage upon multivariate analysis. Conclusion. Delayed presentation in septic shock, preoperative hypoalbuminemia, prolonged perforation, operation interval, and large perforation size > 5mm were detected as independent risk factors for leakage. Postoperative tachypnea and tachycardia with increased levels of C-reactive protein and total leucocytic count are alarming signs for incidence of leakage

Introducción. La úlcera péptica perforada es una de las afecciones abdominales críticas que requiere una intervención quirúrgica temprana. La fuga después de la reparación con parche de epiplón representa una de las complicaciones más devastadoras, que aumentan la morbilidad y la mortalidad. Nuestro estudio tuvo como objetivo evaluar los factores de riesgo y los predictores tempranos de fugas. Métodos. Análisis retrospectivo de los datos de los pacientes sometidos a reparación con parche de epiplón por úlcera péptica perforada, en el período comprendido entre enero de 2019 y enero de 2022, en el Hospital Universitario de Mansoura, Egipto. Se recogieron y analizaron estadísticamente variables pre, intra y postoperatorias. Los factores de riesgo asociados a la incidencia de fugas se analizaron mediante análisis univariado y multivariado. Resultados. Este estudio incluyó 123 pacientes que cumplieron con los criterios de inclusión. Se detectó fuga en siete (5,7 %) pacientes. Aunque las comorbilidades asociadas (p=0,01), el ingreso postoperatorio a la unidad de cuidados intensivos (p=0,03) y la hipotensión postoperatoria (p=0,02) fueron factores de riesgo en el análisis univariado, el shock séptico (p=0,001), el retraso en la intervención (p=0,04), la hipoalbuminemia preoperatoria (p=0,017) y el tamaño de la perforación mayor de 5 mm (p=0,04) se encontraron como factores de riesgo de fuga independientes en el análisis multivariado. Conclusión. Se detectaron como factores de riesgo independientes de fuga la presentación tardía en shock séptico, la hipoalbuminemia preoperatoria, la perforación prolongada, el intervalo operatorio y el tamaño de la perforación mayor de 5 mm. La taquipnea posoperatoria y la taquicardia con niveles elevados de proteína C reactiva y recuento leucocitario total son signos de alarma sobre la presencia de fuga.

Estomas: complicaciones, manejo y prevención. Una revisión actual / Stomas: complications, management, and prevention. An updated review

Introducción. La resección segmentaria del intestino y su derivación temporal o definitiva es un procedimiento frecuente en la práctica quirúrgica, que implica la construcción de un estoma. La enfermedad que lleva a la cirugía, las condiciones clínicas del paciente y los aspectos técnicos en la construcción de la ostomía son puntos claves en la evolución posoperatoria. Métodos. Se realizó una revisión de la literatura identificando las complicaciones asociadas a la construcción de estomas, con el objetivo de ofrecer herramientas de tratamiento y toma de decisiones al personal médico involucrado en la atención de estos pacientes. Resultados. La cirugía de urgencia, la inmunosupresión, la obesidad y la técnica en la apertura del orificio en la pared abdominal, favorecen la aparición de complicaciones tempranas que requieren manejo médico o reintervención quirúrgica. Conclusiones. Todo paciente con estoma debe ser valorado minuciosamente por el cirujano y la terapista enterostomal en las primeras 72 horas luego de la cirugía.

Introduction. Segmental resection of the intestine and its temporary or permanent bypass is a frequent procedure in surgical practice, which involves the construction of a stoma. The disease that leads to surgery, the clinical conditions of the patient and the technical aspects in the construction of the ostomy are key points in the postoperative evolution. Methods. A review of the literature was performed, identifying the complications associated with the construction of stomas, with the aim of offering treatment and decision-making tools to the medical personnel involved in the care of these patients. Results. Emergency surgery, immunosuppression, obesity, and the technique used to open the orifice in the abdominal wall favor the appearance of early complications that require medical management or surgical reintervention. Conclusions. Every patient with a stoma must be carefully evaluated by the surgeon and the enterostomal therapist in the first 72 hours after surgery.

Efficacy and safety of omental wrapping technique for pancreaticojejunal anastomosis in preventing complications after pancreaticoduodenectomy： A Meta-analysis / 临床肝胆病杂志

ObjectiveTo systematically evaluate the efficacy and safety of omental wrapping technique for pancreaticojejunal anastomosis in preventing complications after pancreaticoduodenectomy. MethodsThis study was conducted according to the PRISMA guideline. English and Chinese databases including CNKI， Wanfang Data， VIP， CBM， the Cochrane Library， PubMed， Embase， and Web of Science were searched for clinical studies on omental wrapping technique for pancreaticojejunal anastomosis in preventing complications after pancreaticoduodenectomy published up to November 2022， and Stata 16 and Review Manager 5.4 were used to perform the meta-analysis. ResultsA total of 15 studies with 1 830 patients were included in this study. The meta-analysis showed that the omental wrapping group had a significantly lower overall incidence rate of postoperative pancreatic fistula （POPF） than the non-omental wrapping group （odds ratio ［OR］=0.30， 95% confidence interval ［CI］： 0.22‍ ‍—‍ ‍0.41， P<0.001）， and the subgroup analysis showed that the omental wrapping group had a significantly lower incidence rate of grade B/C POPF than the non-omental wrapping group （OR=0.29， 95%CI： 0.21‍ ‍—‍ ‍0.39， P<0.001）. Compared with the non-omental wrapping group， the omental wrapping group had significantly lower incidence rates of postoperative bile leakage （OR=0.30， 95%CI： 0.16‍ ‍—‍ ‍0.56， P<0.001）， postoperative hemorrhage （OR=0.35， 95%CI： 0.24‍ ‍—‍ ‍0.53， P<0.001）， delayed gastric emptying （OR=0.45， 95%CI： 0.31‍ ‍—‍ ‍0.64， P<0.001）， abdominal infection （OR=0.55， 95%CI： 0.40‍ ‍—‍ ‍0.75， P<0.001）， reoperation （OR=0.31， 95%CI： 0.18‍ ‍—‍ ‍0.54， P<0.001）， and death within 30 days after surgery （OR=0.42， 95%CI： 0.22‍ ‍—‍ ‍0.80， P=0.009）， a significantly earlier time to diet （mean difference ［MD］=-0.98， 95%CI： -1.84 to -0.11， P=0.03）， and a significantly shorter length of postoperative hospital stay （MD=-2.44， 95%CI： -4.10 to -0.77， P=0.004）. There were no significant differences between the two groups in the time of operation （MD=-13.68， 95%CI： -28.31 to -0.95， P=0.07） and intraoperative blood loss （MD=-17.26， 95%CI： -57.55 to -23.03， P=0.40）. ConclusionOmental wrapping can reduce the incidence rates of postoperative complications such as pancreatic fistula， bile leakage， postoperative hemorrhage， abdominal infection， and delayed gastric emptying， improve the prognosis of patients， and shorten the length of hospital stay， without increasing surgical difficulty or time of operation.

Long-term outcomes of intraoperative triamcinolone injection versus postoperative oral prednisolone in congenital cataract surgery / Resultados de longo prazo do uso intraoperatório de triancinolona versus oral pós-operatório de prednisolona na cirurgia de catarata congênita

ABSTRACT Purpose: To compare the long-term ocular findings of children that were operated of congenital cataract before the age of two and that received an intraoperative intracameral triamcinolone injection or used postoperative oral prednisolone to modulate ocular inflammation. Methods: All patients who had previously participated in a clinical trial that analyzed the 1-year surgical outcomes of congenital cataract surgery utilizing intracameral triamcinolone (study group) or oral prednisolone (control group) were eligible to participate in this prospective cohort research. Patients' medical records were reviewed, and the children underwent a complete ophthalmologic exam on final follow-up. Biomicroscopic findings, intraocular pressure, central corneal thickness, the need for additional surgical interventions, and findings compatible with glaucoma were the primary end measures. Results: Twenty-six eyes (26 patients) were included (study group = 11 eyes; control group = 15 eyes). The mean follow--up was 8.2 ± 1.2 years and 8.1 ± 1.7 years in the study and control groups, respectively (p=0.82). All eyes presented a centered intraocular lens. There was no statistically significant difference between the groups with regards to the presence of posterior synechia (p=0.56), intraocular pressure (p=0.49), or central corneal thickness (p=0.21). None of the eyes fulfilled the glaucoma diagnostic criteria, presented secondary visual axis obscuration, or were reoperated. Conclusion: The long--term ocular findings of children that underwent congenital cataract surgery and received an intraoperative intracameral triamcinolone injection were similar to those that used postoperative oral prednisolone to modulate ocular inflammation. This suggests that intracameral triamcinolone may substitute oral prednisolone in congenital cataract surgery, facilitating the postoperative treatment regimen and compliance.

RESUMO Objetivo: Comparar os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita antes dos dois anos de idade e receberam uma injeção intracameral de triancinolona no intraoperatório ou usaram prednisolona oral no pós-operatório para modular a inflamação ocular. Métodos: Neste estudo prospectivo de coorte, todos os pacientes que participaram de um ensaio clínico anterior, que analisou os resultados cirúrgicos de 1 ano da cirurgia de catarata congênita usando triancinolona intracameral (Grupo de Estudo) ou prednisolona oral (Grupo Controle), eram elegíveis para participar. Os prontuários médicos dos pacientes foram revisados e as crianças foram submetidas a um exame oftalmológico completo no acompanhamento final. As principais medidas de desfecho foram: achados biomicroscópicos, pressão intraocular, espessura central da córnea, a necessidade de intervenções cirúrgicas adicionais e achados compatíveis com glaucoma. Resultados: Vinte e seis olhos (26 pacientes) foram incluídos (Grupo de Estudo = 11 olhos; Grupo de Controle = 15 olhos). O seguimento médio foi de 8,2 ± 1,2 anos e 8,1 ± 1,7 anos nos Grupos de Estudo e Controle, respectivamente (p=0,82). Todos os olhos apresentavam lente intraocular centrada. Não houve diferença estatisticamente significativa entre os grupos com relação à presença de sinéquia posterior (p=0,56), pressão intraocular (p=0,49) ou espessura central da córnea (p=0,21). Nenhum dos olhos preencheu os critérios diagnósticos para glaucoma, apresentou opacificação secundária do eixo visual ou foi reoperado. Conclusão: Os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita e receberam uma injeção intracameral de triancinolona no intraoperatório foram semelhantes aos que usaram prednisolona oral no pós-operatório para modular a inflamação ocular, sugerindo que a triancinolona intracameral pode substituir a prednisolona oral na cirurgia de catarata congênita, facilitando o tratamento pós-operatório e a adesão ao mesmo.

Complicated trabeculectomy converted into ab externo cyclodialysis

ABSTRACT The creation of a scleral flap during trabeculectomy can be complicated by a buttonhole, partial amputation at the limbus, and extensive thinning. In some cases, the procedure must be aborted to prevent more serious postoperative complications. This report describes a technique of converting complicated trabeculectomy into ab externo cyclodialysis. A 41-year-old patient with congenital glaucoma presented with a perforated scleral wall with the choroidal tissue exposed during the dissection of the partial-thickness scleral flap. By using a Barraquer cyclodialysis spatula through the scleral perforation, the choroid was separated from the sclera up to the scleral spur over 30° into the anterior chamber. The sclera and conjunctiva/Tenon were sutured with 10-0 nylon single sutures. Two months later, the intraocular pressure was reduced to 16 mmHg with no hypotensive topical medications. This case illustrates an alternative approach to managing a flap-related perioperative complication in trabeculectomy, which yielded good early results.

Outcomes of Minimally Invasive Aortic Valve Replacement in Obese Patients: A Propensity-Matched Study

ABSTRACT Introduction: Obese patients are at risk of complications after cardiac surgery. The aim of this study is to investigate safety and efficacy of a minimally invasive approach via upper sternotomy in this setting. Methods: We retrospectively reviewed 203 obese patients who underwent isolated, elective aortic valve replacement between January 2014 and January 2023 - 106 with minimally invasive aortic valve replacement (MIAVR) and 97 with conventional aortic valve replacement (CAVR). To account for baseline differences, a propensity-matching analysis was performed obtaining two balanced groups of 91 patients each. Results: The 30-day mortality rate was comparable between groups (1.1% MIAVR vs. 0% CAVR, P=0.99). MIAVR patients had faster extubation than CAVR patients (6 ± 2 vs. 9 ± 2 hours, P<0.01). Continuous positive airway pressure therapy was less common in the MIAVR than in the CAVR group (3.3% vs. 13.2%, P=0.03). Other postoperative complications did not differ significantly. Intensive care unit stay (1.8 ± 1.2 vs. 3.2 ± 1.4 days, P<0.01), but not hospital stay (6.7 ± 2.1 vs. 7.2 ± 1.9 days, P=0.09), was shorter for MIAVR than for CAVR patients. Follow-up survival was comparable (logrank P-value = 0.58). Conclusion: MIAVR via upper sternotomy has been shown to be a safe and effective option for obese patients. Respiratory outcome was promising with shorter mechanical ventilation time and reduced need for post-extubation support. The length of stay in the intensive care unit was reduced. These advantages might be important for the obese patient to whom minimally invasive surgery should not be denied.

ABSTRACT 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.

Paracentral acute middle maculopathy in the immediate postoperative of cataract surgery / Maculopatia média aguda paracentral no pós-operatório imediato de cirurgia de catarata

ABSTRACT This case report identified paracentral acute middle maculopathy as the cause of severe and irreversible vision loss after cataract surgery. Cataract surgeons should be aware of known risk factors for the development of paracentral acute middle maculopathy. In those patients, extra care regarding anesthesia, intraocular pressure, and some other aspects of cataract surgery must be taken. Paracentral acute middle maculopathy is currently understood as a clinical sign evident on spectral-domain optical coherence tomography, and it is probably evidence of deep ischemic insult to the retina. It should be a differential diagnosis in cases of marked low vision acuity associated with no fundus abnormalities in the immediate postoperative period, as demonstrated in the presented case.

RESUMO O presente relato de caso identificou a maculopatia média aguda paracentral como a causa de baixa de acuidade visual severa e irreversível após cirurgia de catarata. Existem fatores de risco bem estabelecidos para o desenvolvimento da maculopatia média aguda paracentral que devem ser conhecidos pelos cirurgiões de catarata. Nesse contexto cirúrgico, precauções extras no tocante a procedimentos anestésicos, pressão intraocular e alguns outros aspectos da cirurgia devem ser consideradas. A maculopatia média aguda paracentral é descrita como um sinal clínico observado no exame de tomografia de coerência óptica por domínio espectral e se trata, provavelmente, da evidência de um evento isquêmico no tecido vascular retiniano. Esse diagnóstico deve ser cogitado nos casos de perda de acuidade visual súbita no pós-operatório imediato associada com exame fundoscópico normal, como evidenciado no caso apresentado.

Bocio endotorácico / Endothoracic Goiter

Introducción: Un bocio se considera intratorácico cuando más de un 50 por ciento de la glándula tiroides está en el mediastino, o sea, por debajo del nivel del estrecho torácico superior. Se trata de una enfermedad poco frecuente que padece aproximadamente el 3 por ciento de los pobladores del mundo. La incidencia del bocio nodular ha disminuido debido a la ingestión en algunos países de sal yodada y alimentos ricos en yodo. Esta enfermedad alcanza alrededor del 10 por ciento de las masas mediastínicas. Objetivo: Presentar el caso de un paciente masculino, operado de bocio endotorácico en la provincia de Cienfuegos. Presentación de caso: Se presenta un paciente masculino, de 48 años de edad, que acude a consulta y refiere aumento de volumen del cuello en la región anterior, que se acompaña de decaimiento y en ocasiones disfagia tanto a los alimentos líquidos como a los sólidos. Además, refiere ligera disnea que tolera adecuadamente cuando realiza las actividades de la vida diaria. Por tratarse de una enfermedad poco frecuente, se considera de interés científico publicar el caso para conocimiento de los profesionales dedicados al estudio y tratamiento de las afecciones tiroideas. Conclusiones: El bocio endotorácico es una entidad poco frecuente y en todos los casos requiere de intervención quirúrgica(AU)

Introduction: A goiter is considered intrathoracic when more than 50 percent of the thyroid gland is in the mediastinum; in other words, below the level of the superior thoracic outlet. It is a rare disease that affects approximately 3 percent of the world's population. The incidence of nodular goiter has decreased due to the ingestion of iodized salt and iodine-rich foods in some countries. This disease accounts for about 10 percent of mediastinal masses. Objective: To present the case of a male patient operated on for endothoracic goiter in the province of Cienfuegos. Case presentation: The case is presented of a 48-year-old male patient who comes for consultation referring a volume increase in the anterior neck region, accompanied by decay and sometimes dysphagia to both liquid and solid food. In addition, he reports slight dyspnea that he tolerates adequately when performing daily living activities. Since this is a rare disease, it is considered of scientific interest to publish the case for the knowledge of professionals dedicated to studying and treating thyroid disorders. Conclusions: Endothoracic goiter is a rare entity and, in all cases, requires surgical intervention(AU)

Traqueostomía abierta en el sistema de salud de Malvinas Argentinas. Nuestra Experiencia / Open tracheostomy in Malvinas Argentinas health system. Our experience

Introducción: la traqueostomía es la abertura y el abocamiento de la tráquea al exterior realizada para lograr una vía aérea controlable y permeable. El abordaje puede ser percutáneo y abierto, bajo anestesia general o local, de forma urgente o programada. Objetivo: describir la técnica quirúrgica realizada habitualmente en el sistema de salud de Malvinas Argentinas y evaluar indicaciones y complicaciones. Materiales y métodos: estudio descriptivo retrospectivo que incluyó pacientes con traqueostomía, mayores de 18 años, sin distinción de sexo, realizada entre enero de 2015 y junio de 2018 en Malvinas Argentinas. Resultados: se operaron 72 pacientes, 11 anestesia local y 61 anestesia general; 15 urgencias y 57 programados. La edad promedio fue 34,7. La técnica utilizada fue abierta con incisión horizontal. Las principales indicaciones: intubación orotraqueal prolongada en 34 pacientes, síndrome obstructivo laríngeo agudo (SOLA) en 25 y destete dificultoso en 6. Las complicaciones más frecuentes: lesiones laringotraqueales en 9 pacientes, infección de herida quirúrgica en 5 y enfisema subcutáneo en 3. Discusión: la técnica abierta no es la única existente en la bibliografía, pero buenos resultados en nuestro servicio afirman su seguridad por mejor reconocimiento de estructuras anatómicas y abocamiento de la tráquea. No es posible concluir cuál técnica es superior con respecto a morbimortalidad. Existen diferencias en el lugar donde se realiza, y puede hacerse en quirófano o junto a la cama del paciente con adecuada asepsia. Conclusión: en la actualidad sigue siendo la técnica de elección para la realización de este procedimiento en nuestro servicio.

Introduction: Tracheostomy is the opening and entrance of the trachea to the outside carried out to achieve a controllable and patent airway. The approach can be percuta-neous and open, under general or local anesthesia, urgently or scheduled. Objective:Describe the surgical technique usually performed in Malvinas Argentinas Health System and evaluate indications and complications. Materials and methods: Retros-pective descriptive study, including of patients with tracheostomy, over 18 years of age, without distinction of sex, carried out between January 2015 and June 2018, in Malvinas Argentinas. Results: 72 patients underwent surgery, 11 local anesthesia, 61 general; 15 emergency, and 57 scheduled. Average age 34.7. The technique used was open with a horizontal incision. The main indications were prolonged orotra-cheal intubation in 34 patients, acute laryngeal obstructive syndrome (AOLS) in 25, and difficult weaning in 6. The most frequent complications were laryngotracheal injuries in 9 patients, surgical wound infection in 5, and subcutaneous emphysema in 3. Discussion: Open technique is not the only one existing in the literature, but the good results in our service confirm its safety due to better recognition of anatomical structures and opening of the trachea. It is not possible to conclude which technique is superior, with respect to morbidity and mortality. There are differences in the place where it is performed, and it can be done in the operating room or next to the patient's bed with adequate asepsis. Conclusion: Currently, it continues to be the technique of choice for performing this procedure in our service.

Risk factors for severe postoperative complications after oncologic right colectomy

This study aims to examine the possible risk factors for severe postoperative sequelae following oncologic right colectomy. This retrospective analysis included all consecutive patients with right colon cancer who had right colectomy in our department from 1st Jan 2022 to 31st Dec 2023. The Clavien-Dindo grading system was employed to assess postoperative problems. Univariate and multivariate logistic regression analysis were done to look into risk variables for serious postoperative complications. Of the 21 patients, there were 10 males and 11 females, with a median age of 68 (IQR 60­78). Postoperative morbidity and mortality rates were 42.85% (9 patients) and 9.52% (2 patients), respectively. The anastomotic leak rate was 4.76% (1 patient). Severe postoperative complications (Clavien­ Dindo grades III­V) were present in 3 patients (14.28%). Univariate analysis showed the following as risk factors for postoperative severe complications: Charlson score, lack of mechanical bowel preparation, level of preoperative proteins, blood transfusions, and degree of urgency (elective/emergency right colectomy). In the logistic binary regression, the Charlson score (OR = 1.932, 95% CI = 1.077­ 3.463, p = 0.025) and preoperative protein level (OR = 0.048, 95% CI = 0.006­0.433, p = 0.007) were found to be independent risk factors for postoperative severe complications. Severe consequences after oncologic right colectomy are linked to a low preoperative protein level and a higher Charlson comorbidity index

Histerectomía total laparoscópica: resultados perioperatorios en 10 años de experiencia / Single-center cohort study of perioperative outcomes on total laparoscopic hysterectomy (TLH): a 10-year experience

Resumen Introducción : La extirpación del útero, (histerectomía) es la cirugía más frecuente en ginecología. En Argentina existen pocas publicaciones sobre los resultados perio peratorios de este tipo de procedimiento, y menos aún sobre histerectomía mínimamente invasiva. El objetivo de este estudio fue determinar la tasa de complica ciones perioperatorias en pacientes con histerectomía total laparoscópica realizada en el Hospital Italiano de Buenos Aires, desde el 7 de enero de 2010 al 22 de diciembre de 2020. Métodos : estudio de cohorte retrospectivo donde se revisaron las historias clínicas electrónicas de pacien tes sometidas a una histerectomía laparoscópica en el período mencionado. Se evaluaron las complicaciones intraquirúrgicas y postoperatorias utilizando la clasifi cación validada de Clavien-Dindo. Resultados : Se incluyeron 1014 pacientes. La tasa de complicaciones intraquirúrgicas fue de 4.5%. Se halló una tasa de complicaciones postoperatorias de 16.6% (n=168), siendo 12.3% (n=125) Clavien-Dindo ≤ 2, y 4.2% (n=43) Clavien-Dindo ≥ 3. En el análisis multivariable que se ajustó por peso uterino >170g, edad, índice de masa corporal y más de dos cirugías abdominales pre vias, se encontró asociación entre peso uterino > 170 g y complicaciones postoperatorias, OR 1.49, IC 95% 1.04- 2.14, p = 0.03. Discusión : Al evaluar el porcentaje de complicaciones menores y mayores, nuestros números se encuentran dentro de los parámetros aceptables para realizar este tipo de cirugía, más aún, considerando que la evaluación se realizó en un ámbito educativo.

Abstract Introduction : The removal of the uterus, (hysterec tomy), is the most frequent surgery in gynecology. In Argentina there are few publications on the periopera tive results of this type of procedure, and even less on minimally invasive hysterectomy. The objective of this study was to determine the rate of perioperative compli cations in patients with total laparoscopic hysterectomy performed at Hospital Italiano de Buenos Aires, from January 7, 2010 to December 22, 2020. Methods : retrospective cohort study where electronic medical records were reviewed. Intrasurgical and postop erative complications were evaluated using the validated Clavien-Dindo's classification. Results : 1014 patients were included. The rate of intra-surgical complications was 4.5%. In respect to postoperative complications, there was found a rate of 16.6% (n=168), being 12.3% (n=125) Clavien-Dindo ≤ 2, and 4.2% (n=43) Clavien-Dindo ≥ 3. In a multivariable analysis that adjusted for uterine weight > 170g, age, body mass index, and more than two previous abdomi nal surgeries, an association was found between uterine weight >170g and postoperative complications OR 1.49, 95% CI 1.04- 2.14, p=0.03. Discussion : When evaluating the percentage of mi nor and major complications, our findings are within the acceptable parameters for performing this type of surgery, even though the evaluation was carried out in an educational setting.

Fatores de Risco para Infecção da Ferida Operatória em Pacientes Submetidos à Cirurgia Cardíaca Pediátrica / Risk Factors for Surgical Site Infection in Patients Undergoing Pediatric Cardiac Surgery

Resumo Fundamento A infecção do sítio cirúrgico (ISC) é uma importante complicação no pós-operatório de cirurgia cardíaca pediátrica associada ao aumento da morbimortalidade. Objetivos Identificar fatores de risco para a ISC após cirurgias cardíacas para correção de malformações congênitas. Métodos Este estudo caso-controle incluiu 189 pacientes com um ano completo e 19 anos e 11 meses, submetidos à cirurgia cardíaca em hospital universitário terciário de cardiologia de janeiro de 2011 a dezembro de 2018. Foi realizado registro e análise de dados pré, intra e pós-operatórios. Para cada caso foram selecionados dois controles, conforme o diagnóstico da cardiopatia e cirurgia realizada em um intervalo de até 30 dias para minimizar diferenças pré e/ou intraoperatórias. Para a análise dos fatores de risco foi utilizado o modelo de regressão binária logística. Significância estatística definida como valor de p<0,05. Resultados O estudo incluiu 66 casos e 123 controles. A incidência de ISC variou de 2% a 3,8%. Fatores de risco identificados: faixa etária de lactentes (OR 3,19, IC 95% 1,26 - 8,66, p=0,014), síndrome genética (OR 6,20, IC 95% 1,70 - 21,65, p=0,004), RACHS-1 categorias 3 e 4 (OR 8,40, IC 95% 3,30 - 21,34, p<0,001), o valor da proteína C reativa (PCR) de 48 horas pós-operatórias foi demonstrado como fator protetor para esta infecção (OR 0,85, IC 95% 0,73 - 0,98, p=0,023). Conclusão Os fatores de risco identificados não são variáveis modificáveis. Vigilância e medidas preventivas contínuas são fundamentais para reduzir a infecção. O papel do PCR elevado no pós-operatório foi fator protetor e precisa ser melhor estudado.

Abstract Background Surgical site infection is an important complication after pediatric cardiac surgery, associated with increased morbidity and mortality. Objectives We sought to identify risk factors for surgical site infection after pediatric cardiac surgeries. Methods A case-control study included patients aged between 1 year and 19 years and 11 months of age, submitted to cardiac surgery performed at a tertiary cardiac center from January 1 st , 2011, through December 31, 2018. Charts were reviewed for pre-, intra, and postoperative variables. We identified two randomly selected control patients with the same pathophysiological diagnosis and underwent surgery within thirty days of each index case. Univariate and multivariate logistic regression analyses were performed to identify risk factors. Statistical significance was defined as p<0.05. Results Sixty-six cases and 123 controls were included. Surgical site infection incidence ranged from 2% to 3.8%. The following risk factors were identified: Infant age (OR 3.19, 95% CI 1.26 to 8.66, p=0.014), presence of genetic syndrome (OR 6.20, CI 95% 1.70 to 21.65, p=0.004), categories 3 and 4 of RACHS-1 (OR 8.40, CI 95% 3.30 to 21.34, p<0.001), 48 h C-reactive protein level range was detected as a protective factor for this infection (OR 0.85, 95% CI 0.73 to 0.98, p=0.023). Conclusions The risk factors defined in this study could not be modified. Therefore, additional surveillance and new preventive strategies need to be implemented to reduce the incidence of surgical site infection. The increased CRP in the postoperative period was a protective factor that needs further understanding.

Fatores de risco consequentes a complicações no pósoperatório da mastoplastia de aumento primária com implantes de silicone: Estudo retrospectivo / Risk factors resulting from complications in the postoperative period of primary breast augmentation with silicone implants: Retrospective study

Introdução: A mamoplastia de aumento é uma das cirurgias plásticas mais realizadas no mundo. Tendo em vista sua alta aplicabilidade, é fundamental conhecer os fatores de risco relacionados à incidência de complicações pós-operatórias a fim de reduzilas nesse tipo de procedimento. Método: Este estudo é retrospectivo feito por meio da análise dos prontuários de 76 pacientes que realizaram mamoplastia de aumento primária com implantes de silicone durante os meses de janeiro de 2018 a dezembro de 2020. Resultados: Observou-se que a presença de comorbidades aumentou a incidência de complicações pós-operatórias precoces (p<0,001), mas não de complicações pósoperatórias tardias (p=0,8). O maior tempo cirúrgico também aumentou a incidência de complicações pós-operatórias (p=0,005). Conclusão: A presença de comorbidades influencia diretamente na incidência de complicações pós-operatórias da mastoplastia de aumento e por esta razão deve-se realizar uma adequada compensação pré-operatória antes de submeter as pacientes a este procedimento cirúrgico.

Introduction: Breast augmentation is one of the most performed plastic surgeries in the world. Given its high applicability, it is essential to know the risk factors related to the incidence of postoperative complications to reduce them in this type of procedure. Method: This retrospective study analyzed the medical records of 76 patients who underwent primary breast augmentation with silicone implants from January 2018 to December 2020. Results: It was observed that the presence of comorbidities increased the incidence of early postoperative complications (p<0.001) but not of late postoperative complications (p=0.8). Longer surgical time also increased the incidence of postoperative complications (p=0.005). Conclusion: The presence of comorbidities directly influences the incidence of postoperative complications after breast augmentation, and for this reason, adequate preoperative compensation must be carried out before submitting patients to this surgical procedure.
