Introducción: La panlitiasis se define como la presencia de múltiples cálculos en el trayecto de la vía biliar. El manejo consiste en realizar una colangiopancreatografía retrógrada endoscópica (CPRE), la exploración de la vía biliar o la anastomosis biliodigestiva (ABD), ya sea coledocoduodenoanastomosis o hepaticoyeyunoanastomosis.Objetivo: Describir el caso clínico de un paciente con panlitiasis biliar, abordando la presentación clínica, los métodos diagnósticos, el tratamiento y la evolución, con el propósito de ofrecer un recurso sólido a la comunidad médica.Presentación del caso: Se presenta un paciente de 60 años colecistectomizado hace 13 años portador de anastomosis bilioentérica con panlitiasis recidivante, se realizó un lavado de la vía biliar con salida de cálculos y pus del interior, finalmente se colocó una sonda Kehr junto con tratamiento clínico. Presentó una evolución favorable. Discusión: Este caso reveló una panlitiasis a la exploración de las vías biliares bajo visión endoscópica, a pesar de que no se encontró obstrucción, el paciente tenía antecedente de colecistectomía y contaba con una derivación hepático-yeyunal por lesión iatrogénica. La decisión del tratamiento debe ser multidisciplinaria ya que cada caso es único y dependerá de las características del paciente y las condiciones clínicas individuales.Conclusiones: La panlitiasis coledociana recidivante requirió un control farmacológico estricto para evitar recurrencia y la subsecuente exploración de la vía biliar que incrementa la morbimortalidad del paciente. Es importante el seguimiento médico continuo del paciente y la predisposición con la que cuenta para la formación de litos, pudiendo ser prevenidos, identificados y tratados de manera oportuna

Introduction: Panlithiasis is define as the presence of multiple stones in the biliary tract that is classified as primary, secondary, or mixed according to the origin of the stones. Management consists of endoscopic retrograde cholangiopancreatography (ERCP), exploration of the biliary tract, or biliodigestive anastomosis (BDA), either choledochoduodenostomy or hepaticojejunostomy. Objective: Describe the clinical case of a patient with biliary panlithiasis, addressing the cli-nical presentation, diagnostic methods, treatment and evolution, with the purpose of offering a solid resource to the medical community.Case Presentation: We present a 60-year-old male patient who underwent cholecystectomy 13 years ago and has a bilioenteric anastomosis with recurrent panlithiasis. Biliary lavage was performed with the output of stones and pus from the inside. Finally, a Kehr tube was placed along with clinical treatment. The patient showed a favorable outcome.Discussion: This case revealed a panlithiasis upon exploration of the biliary tract under endoscopic vision. Despite finding no obstruction, the patient had a history of cholecystectomy and a hepatic-jejunal diversion due to iatrogenic injury. The treatment decision should be multidisciplinary, as each case is unique and depends on the patient's characteristics and individual clinical conditions.Conclusions: Recurrent choledocholithiasis required strict pharmacological control to prevent recurrence and subsequent exploration of the biliary tract, which increases patient morbidity and mortality. Continuous medical follow-up of the patient and the predisposition with which they have for the formation of stones is important. These can be prevented, identified, and treated in a timely manner.

Neoplasia quística mucinosa en la vía biliar intrahepática. Presentación de dos casos / Mucinous cystic neoplasm in the intrahepatic bile duct. Presentation of two cases

Introducción. Las neoplasias quísticas mucinosas del hígado son tumores poco frecuentes, equivalen a menos del 5 % de todas las lesiones quísticas hepáticas y se originan generalmente en la vía biliar intrahepática, con poco compromiso extrahepático. En la mayoría de los casos su diagnóstico es incidental dado que es una entidad generalmente asintomática con un curso benigno; sin embargo, hasta en el 30 % pueden ser malignas. En todos los casos se debe hacer una resección quirúrgica completa de la lesión. Caso clínico. Se presentan dos pacientes con diagnóstico de neoplasia quística mucinosa en la vía biliar intrahepática, así como sus manifestaciones clínicas, hallazgos imagenológicos y tratamiento. Discusión. Debido a su baja incidencia, esta patología constituye un reto diagnóstico, que se puede confundir con otro tipo de entidades más comunes. El diagnóstico definitivo se hace de forma histopatológica, pero en todos los casos, ante la sospecha clínica, se recomienda la resección completa. Conclusión. Se presentan dos pacientes con diagnóstico de neoplasias quísticas mucinosas del hígado, una entidad poco frecuente y de difícil diagnóstico

Introduction. Mucinous cystic neoplasms of the liver are rare tumors, accounting for less than 5% of all liver cystic lesions, and generally originate from the intrahepatic bile duct with little extrahepatic involvement. In most cases its diagnosis is incidental since it is a generally asymptomatic entity with a benign course; however, up to 30% can have a malignant course. In all cases, complete surgical resection of the lesion must be performed. Clinical case. Two patients with a diagnosis of mucinous cystic neoplasm in the intrahepatic bile duct are presented, as well as their clinical manifestations, imaging findings, and treatment. Discussion. Due to its low incidence, this pathology constitutes a diagnostic challenge, which can be confused with other types of more common entities. The definitive diagnosis is made histopathologically, but in all cases, given clinical suspicion, complete resection is recommended. Conclusion. Two patients with a diagnosis of mucinous cystic neoplasms of the liver are presented, a rare entity that is difficult to diagnose

Diagnóstico y manejo de la colestasis intrahepática en el embarazo / Diagnosis and management of intrahepatic cholestasis in pregnancy

La colestasis intrahepática del embarazo es producida por una disfunción de los hepatocitos, propia de la gestación. Las concentraciones elevadas de hormonas sexuales y la predisposición genética parecen ser factores importantes para su desarrollo. La incidencia depende de la composición étnica de la población y de los criterios diagnósticos utilizados. Está caracterizada por prurito creciente y persistente, aumento de las concentraciones de ácidos biliares, generalmente a finales del segundo o tercer trimestre del embarazo. Lleva a la aparición de hipoxia uteroplacentaria que aumenta el riesgo de líquido amniótico meconial, parto pretérmino, preeclampsia, hemorragia posparto, síndrome de dificultad respiratoria del neonato y muerte perinatal. El manejo terapéutico está dirigido a reducir los síntomas clínicos, normalizar los cambios bioquímicos maternos y prevenir complicaciones fetales. El tratamiento farmacológico principal consiste en la administración de ácido ursodesoxicólico. El objetivo de esta investigación es evaluar el diagnóstico y manejo de la colestasis intrahepática del embarazo(AU)

Intrahepatic cholestasis of pregnancy is caused by a dysfunction of the hepatocytes, typical of pregnancy. High concentrations of sex hormones and genetic predisposition appear to be important factors for their development. The incidence depends on the ethnic composition of the population and the diagnostic criteria used. It is characterized by increasing and persistent pruritus, increased concentrations of bile acids, usually in the late second or third trimester of pregnancy. It leads to the occurrence of uteroplacental hypoxia that increases the risk of meconium amniotic fluid, preterm delivery, preeclampsia, postpartum hemorrhage, neonatal respiratory distress syndrome, and perinatal death. Therapeutic management is aimed at reducing clinical symptoms, normalizing maternal biochemical changes, and preventing fetal complications. The main pharmacological treatment consists of the administration of ursodeoxycholic acid. The objective of this research is to evaluate the diagnosis and management of intrahepatic cholestasis of pregnancy(AU)

Drug-induced bile duct injury: progress and challenges / 中华肝脏病杂志

Drug-induced bile duct injury is a specific kind of drug-induced liver injury that has two main pathological types, namely ductopenia, or vanishing bile duct syndrome, and secondary sclerosing cholangitis. However, in recent years, the reports of new drugs that cause bile duct injury have been constantly increasing, and these drugs have different clinicopathological features and a novel pathogenesis. Therefore, this paper summarizes and analyzes the progress and challenges in the etiology, pathogenesis, diagnosis and treatment, and other aspects of drug-induced bile duct injury.

Clinical study on early predictors of concurrent bile duct injury following TACE in patients with liver cancer / 中华肝脏病杂志

Objective: To explore the predictive factors of concurrent bile duct injury following transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC). Methods: A retrospective study was conducted on 483 HCC patients in relation to TACE postoperative complications. A total of 21 cases of bile duct injury were observed following the TACE procedure. Laboratory data, imaging data, and clinically relevant medical histories were recorded before and after one week following the TACE procedure and follow-up. The χ (2) test, or Fisher's exact probability method, was used for categorical variables. The mean of the two samples was compared using a paired t-test or Wilcoxon rank sum test. The comparison of multiple mean values was conducted using an analysis of variance. Results: Twenty-one cases with bile duct injury had intrahepatic bile duct dilatation, bile tumors, hilar biliary duct stenoses, and other manifestations. 14.3% (3/21) of patients showed linear high-density shadows along the bile duct on a plain CT scan, while 76.2% (16/21) of patients had ALP > 200 U/L one week following TACE procedure, and bile duct injury occurred in later follow-up. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and γ-glutamyl transferase (GGT) were significantly increased in all patients following TACE procedure (t = -2.721, P = 0.014; t = -2.674, P = 0.015; t = -3.079, P = 0.006; t = -3.377, P = 0.003, respectively). Conclusion: The deposition of iodized oil around the bile duct on plain CT scan presentation or the continuous increase of ALP (> 200 U/L) one week following TACE procedure has a certain predictive value for the later bile duct injury.

Research progress in lineage tracing to explore hepatic parenchymal cell regeneration and repair mechanisms / 中华肝脏病杂志

Hepatic parenchymal cells are a type of liver cells that performs important functions such as metabolism and detoxification. The contribution of hepatic parenchymal cells, bile duct cells, and hepatic stem/progenitor cells to new hepatic parenchymal cells in the process of liver injury repair has become a controversial issue due to their strong proliferation ability. Lineage tracing technology, which has emerged in the past decade as a new method for exploring the origin of cells, can trace specific type of cells and their daughter cells by labeling cells that express the specific gene and their progeny. The article reviews the current literature on the origin and contribution of hepatic parenchymal cells by this technique. About 98% of new hepatic parenchymal cells originate from the existing hepatic parenchymal cells during liver homeostasis and after acute injury. However, under conditions of severe liver injury, such as inhibition of hepatic parenchymal cell proliferation, bile duct cells (mainly liver stem/progenitor cells) become the predominant source of hepatic parenchymal cells, contributing a steady increased hepatocyte regeneration with the extension of time.

Ultrasonographic aspects of the gallbladder mucocele in 30 dogs: retrospective study / Aspectos ultrassonográficos da mucocele biliar em 30 cães: estudo retrospectivo

Gallbladder mucocele is characterized by hyperplasia of the gallbladder epithelium, increased mucus production, accumulation, and densification of the bile content, which can lead to biliary obstruction, necrosis, and rupture of the gallbladder wall. Its finding may be accidental or related to symptoms. A retrospective study (2016-2019) was carried out based on abdominal ultrasound examinations in dogs, correlating aspects of the gallbladder and biliary system in the mucocele with existing comorbidities. Thirty dogs diagnosed with biliary mucocele were evaluated, of which 46.66% had the disease at an early stage, and 53.33% showed a more advanced stage. Of these, 66.66% were related to endocrinopathies and hyperadrenocorticism. Signs of extrahepatic bile duct obstruction and biliary peritonitis were observed in two animals. Due to their potential risk of complications, follow-up ultrasound assessments are indicated in cases that opt for clinical treatment, not excluding the need for surgical intervention.(AU)

A mucocele biliar caracteriza-se pela hiperplasia do epitélio da vesícula biliar, aumento da produção de muco, acúmulo e densificação do conteúdo biliar, podendo levar à obstrução, necrose e ruptura da parede da vesícula biliar. Seu achado pode ser acidental ou estar relacionado à sintomatologia. Foi realizado um estudo retrospectivo (2016-2019) a partir de exames ultrassonográficos abdominais em cães, correlacionando os aspectos da vesícula biliar na mucocele, com comorbidades existentes. Foram avaliados 30 cães com diagnóstico de mucocele biliar, dos quais 46,66% apresentaram a doença em estágio inicial e 53,33% demonstraram estágio mais avançado. Destes, 66,66% tinham endocrinopatias, principalmente hiperadrenocorticismo. Sinais de obstrução de vias biliares extra-hepáticas e peritonite biliar foram observados em dois animais. Por seu potencial risco de complicação, avaliações ultrassonográficas de seguimento são indicadas nos casos de tratamento clínico, não se descartando a necessidade de intervenção cirúrgica.(AU)

Papel del ácido ursodesoxicólico en 40 años de tratamiento para la colangitis biliar primaria / Role of ursodeoxycholic acid in 40 years of treatment for primary biliary cholangitis

La colangitis biliar primaria es una enfermedad hepática autoinmune que conduce a la destrucción progresiva de los conductos biliares intrahepáticos, lo que aumenta el riesgo de desarrollar cirrosis e hipertensión portal. Actualmente, el ácido ursodesoxicólico es el medicamento de primera línea para el tratamiento de esta entidad. Este medicamento desplaza los ácidos biliares hidrofóbicos y aumenta las concentraciones de ácidos biliares hidrofílicos en la bilis, lo cual favorece la integridad de los conductos biliares, adicionalmente, tiene efectos antiinflamatorios y propiedades inmunomo-duladoras y antiapoptóticas. En los últimos 40 años, numerosos ensayos clínicos han respaldado la eficacia clínica del ácido ursodesoxicólico y su seguridad cuando se utiliza en pacientes con colan-gitis biliar primaria. Se realiza una revisión del ácido ursodesoxicólico en el contexto de colangitis biliar primaria, se describe su historia, mecanismos de acción, efectos secundarios y dosificación. Finalmente, se menciona su uso en situaciones especiales como son el embarazo y la lactancia

Primary biliary cholangitis is an autoimmune liver disease that leads to progressive destruction of intrahepatic bile ducts, increasing the risk of developing cirrhosis and portal hypertension. Currently, ursodeoxycholic acid is the first-line drug for the treatment of this condition. This drug displaces hy-drophobic bile acids and increases concentrations of hydrophilic bile acids in the bile, which favors the integrity of the bile ducts, additionally, it has anti-inflammatory effects and immunoprotective and antiapoptotic properties. Over the past 40 years numerous clinical trials have supported the clinical efficacy of ursodeoxycholic acid and its safety when used in patients with primary biliary cholangitis. A review of ursodeoxycholic acid in the context of primary biliary cholangitis is carried out, and its history, mechanisms of action, side effects and dosage are described. Finally, its use in special situations such as pregnancy and lactation are discussed.

Doble colédoco, variante anatómica infrecuente de la vía biliar. Presentación de caso / Double common bile duct, a rare anatomical variant of the bile tract. Case report

Introducción: la presencia de un conducto colédoco doble es una variante anatómica infrecuente con menos de 200 casos publicados en la literatura hasta la fecha, siendo fundamental los estudios preoperatorios que se le deben realizar a los pacientes, a fin de tener la sospecha o el diagnóstico confirmado, no sólo de la variante anatómica, sino de la patología asociada, siendo estas la coledocolitiasis y las patologías malignas del árbol biliar las más frecuentes, aunque gran parte de los casos son hallazgos incidentales e intraoperatorios.Caso clínico : se presenta el caso de masculino de 81 años de edad, con antecedente de colecistectomía 20 años previos, con diagnóstico de síndrome ictérico obstructivo, y estudios de colangiorresonancia y CPRE que reportan coledocolitiasis. Se decide llevar a acto quirúrgico y se diagnóstica la presencia de conducto colédoco doble como hallazgo. Se realiza derivación biliodigestiva de tipo hepaticoyeyunoanastomosis más ligadura de conducto colédoco accesorio con evolución satisfactoria, con alta médica a los 5 días posteriores, y resultado de biopsia negativo para malignidad.Conclusión : el doble colédoco debe ser adecuadamente diagnosticado y estudiado, así no se confirme el diagnóstico preoperatorio los pacientes deben acudir con estos estudios realizados al acto quirúrgico, ya que, dicho tratamiento dependerá fundamentalmente de la patología asociada(AU)

Introduction: the presence of a double common bile duct is an infrequent anatomical variant with less than 200 cases published in the literature to the date, and preoperative studies that must be performed on patients are essential in order to have the suspicion or diagnosis confirmed, not only of the anatomical variant, but also of the associated pathology, these being choledocholithiasis and malignant pathologies of the biliary tract the most frequent, although most of the cases are incidental and intraoperative findings.Clinical case : the case of an 81-year-old male is presented, with a history of cholecystectomy 20 years prior, with a diagnosis of obstructive icteric syndrome, and magnetic resonance cholangiography and ERCP studies that reported choledocholithiasis. It was decided to carry out surgery and the presence of double common bile duct was diagnosed as a finding. Biliodigestive derivation hepaticojejunoanastomosis type and accessory common bile duct ligation was performed with satisfactory evolution, with medical discharge 5 days later, and biopsy result negative for malignancy.Conclusion : the double common bile duct should be properly diagnosed and studied, even if the preoperative diagnosis is not confirmed, patients should attend the surgical procedure with these studies, since said treatment will depend fundamentally on the associated pathology(AU)

Síndrome biliar obstructivo no litiásico o de Lemmel. ¿Es tan infrecuente como parece? / Non-lithiasic obstructive biliary syndrome or Lemmel's syndrome. Is it as rare as it seems?

Introducción. Aproximadamente el 5 % de los divertículos duodenales pueden causar síntomas y el 1 % presentar complicaciones, siendo la colangitis la más frecuente. El síndrome de Lemmel corresponde a un tipo de ictericia obstructiva intermitente, asociado a la presencia de divertículos periampulares y disfunción del esfínter de Oddi, sin presencia de coledocolitiasis. Método. Se realizó una revisión sistemática de la literatura en Pubmed, Google Académico y ProQuest, con los términos: síndrome de Lemmel, divertículo duodenal sintomático e ictericia obstructiva intermitente. Resultados. Se encontraron 38 casos, siendo España el país con mayor número, seguido de México, Japón y Colombia. No hay diferencias de distribución con respecto al género. El tratamiento más frecuentemente empleado fue la colangio pancreatografia retrógrada endoscópica. Conclusión. El síndrome de Lemmel es poco frecuente, sin un cuadro clínico especifico, con un incremento en los casos informados en los últimos años, posiblemente debido a la mejor disponibilidad de métodos diagnósticos. Es más frecuente en pacientes en la octava década de la vida y su tratamiento generalmente es endoscópico

Introduction. Approximately 5% of duodenal diverticula can cause symptoms and 1% have complications, cholangitis being the most common. Lemmel syndrome corresponds to a type of intermittent obstructive jaundice, associated with the presence of peri-ampullary diverticula and sphincter of Oddi dysfunction, without choledocholithiasis. Method. A systematic review of the literature was carried out in Pubmed, Google Scholar, ProQuest, with the terms: Lemmel syndrome, symptomatic duodenal diverticulum, and intermittent obstructive jaundice.Results. 38 cases were found, Spain being the country with the highest number, followed by Mexico, Japan and Colombia. There are no differences in distribution with respect to gender. The most frequently used treatment was endoscopic retrograde cholangiopancreatography.Conclusion. Lemmel syndrome is a rare disease, without a specific clinical presentation, with an increase in reported cases in recent years possibly due to the better availability of diagnostic methods. It is more frequent in patients in the eighth decade of life and its treatment is generally endoscopic

Lesiones de vía biliar poscolecistectomía: conducta terapéutica actual / Post Cholecystectomy Bile Duct Injuries: Current Therapeutic Option

Resumen La colecistolitiasis es una condición común en Chile. La complicación más frecuente de esta condición es la colecistitis aguda. Aproximadamente 60.000 colecistectomías son realizadas anualmente en nuestro país, convirtiéndola en una de las patologías digestivas más frecuentes. El tratamiento de la colelitiasis ha evolucionado las últimas dos décadas. Con el desarrollo de la laparoscopía a final de 1980, la colecistectomía abierta fue definitivamente sustituida en los 90 por la vía laparoscópica. Desafortunadamente, la generalización de este procedimiento produjo un aumento en la incidencia de lesiones de vía biliar, aumentando desde una 0,1-0,2% hasta un 0,5-0,7%. Si bien, con el progresivo entrenamiento de los cirujanos en la cirugía mínimamente invasiva esta cifra ha disminuido nuevamente, la LVB aún constituye una de las complicaciones más graves en cirugía, generando gran impacto en la calidad de vida del paciente, e incluso costos en salud que pueden llegar a ser devastadores. El manejo de una lesión de vía biliar es, para muchos cirujanos, un desafío quirúrgico, que para su resolución requiere de las habilidades y experiencia de un cirujano hepatobiliar y derivación a centros de salud especializados. Sin duda, la acción más importante es extremar de manera rutinaria las medidas de prevención. Sin embargo, una vez que la lesión se ha producido, el futuro del paciente depende, directamente, del buen criterio del cirujano, tanto para realizar un diagnóstico temprano, como del enfrentamiento terapéutico que realice. El objetivo de este trabajo es dar a conocer diferentes conductas preventivas y terapéuticas cuando esta complicación se presenta.

Calculous biliary disease is a common condition in Chile. Over 60.000 cholecystectomies are performed annually, making gallstone disease one of the most common digestive health problems. The treatment of calculous biliary disease has evolved over the last 2 decades. With the development of laparoscopic technology in the late 1980s, new techniques for cholecystectomy were introduced. By the early 1990s, laparoscopic cholecystectomy had replaced open cholecystectomy in the operative management of gallbladder stone disease. Unfortunately, the widespread application of laparoscopic cholecystectomy has led to a concurrent rise in the incidence of major bile duct injuries. Reports have estimated the incidence has risen from 0.1-0.2 to 0.5-0.7%. Although, exponential training of surgeons in minimally invasive surgery has led to decrease this numbers again, bile duct injuries still constitute one of the most serious complications in surgery, generating a great impact on the patient's quality of life, and even health costs that can be devastating. The management of patients following major bile duct injurie is a surgical challenge, often requiring the skills of experienced hepatobiliary surgeons at tertiary referral centers. In this setting, the most important action is to routinely maximize prevention measures. However, once injury has occurred, patient's future depends directly on the correct judgment of the surgeon, both to make an early diagnosis and to choose the best therapeutic confrontation. The objective of this article is to present the different preventive and therapeutic options available when this complication occurs.

Calidad de vida posterior a reconstrucción de vía biliar / Quality of life of patients who underwent a bile duct reconstruction

BACKGROUND: Bile duct reconstruction (BDR) secondary to bile duct injury during cholecystectomy (BDIC) is a complex surgery, and an important issue is the quality of life (QL) after the procedure. AIM: To compare the QL of a cohort of patients who underwent BDR due to BDIC with a cohort of patients who underwent a cholecystectomy without incidents. MATERIAL AND METHODS: The cohort was composed of 32 patients aged 47 ± 18 years (78% women) who underwent BDR due to BDIC. For purposes of comparison, a cohort of patients who underwent a cholecystectomy without incident was chosen. These cohorts were paired 1:1 by age (± 1 year), gender and type of surgery. The SF-36 quality of life survey was applied in person or by telephone. The score was calculated as proposed by the RAND group. RESULTS: The cohort of BDR patients was comprised of 32 patients, with an average age of 47 ± 17.6 years, with a predominance of women (78%). The mean number of hospitalization days among BDR patients was 20 ± 11.8. The average follow-up was 7 ± 5 years. The mean score of patients undergoing RVB or cholecystectomy without complications was evaluated, without finding differences in the score of the different domains of the SF-36 scale. Conclusions: In the present study no significant differences were found in QL between the patients with BDIC who underwent BDR and patients who underwent a cholecystectomy without complications.

Lesión quirúrgica de vía biliar compleja. Manejo conservador / Complex bile duct injury. Conservative management

RESUMEN La colecistectomía laparoscópica es el tratamiento de elección para la litiasis vesicular sintomática. Aunque la tasa de complicaciones es baja, las lesiones de la vía biliar representan un grave problema. La asociación con una lesión vascular (lesión compleja) genera un impacto adicional, disminuyendo la calidad de vida y la sobrevida a largo plazo. Presentamos el caso de una paciente con lesión compleja por compromiso vascular del pedículo hepático derecho que desarrolló una atrofia del parénquima correspondiente. Ante la ausencia de complicaciones sépticas, el tratamiento no operatorio pudo realizarse en forma exitosa.

ABSTRACT Laparoscopic cholecystectomy is considered the standard of care for symptomatic cholelithiasis. Although the rate of complications is low, bile duct injuries represent a serious problem. The association with vascular injury (complex injury) poses an additional impact by reducing the quality of life and long-term survival. We report the case of a female patient with complex injury due to vascular involvement of the right hepatic pedicle who developed right liver atrophy. Non-operative management was successful due to the absence of septic complications.
