INDURG TRIAL Protocol: A Randomized Controlled Trial Using Indocyanine Green during Cholecystectomy in Acute Cholecystitis.

INTRODUCTION: Laparoscopic cholecystectomy is one of the most common gastrointestinal surgeries, and bile duct injury is one of its main complications. The use of real-time indocyanine green fluorescence cholangiography allows the identification of extrahepatic biliary structures, facilitating the procedure and reducing the risk of bile duct lesions. A better visualization of the bile duct may help to reduce the need for conversion to open surgery, and may also shorten operating time. The main objective of this study was to determine whether the use of indocyanine green is associated with a reduction in operating time in emergency cholecystectomies. Secondary outcomes are the postoperative hospital stay, the correct intraoperative visualization of the Calot's Triangle structures with the administration of indocyanine green, and the intraoperative complications, postoperative complications and morbidity according to the Clavien-Dindo classification. METHODS: This is a randomized, prospective, controlled, multicenter trial with patients diagnosed with acute cholecystitis requiring emergency cholecystectomy. The control group will comprise 220 patients undergoing emergency laparoscopic cholecystectomy applying the standard technique. The intervention group will comprise 220 patients also undergoing emergency laparoscopic cholecystectomy for acute cholecystitis with prior administration of indocyanine green. CONCLUSION: Due to the lack of published studies on ICG in emergency laparoscopic cholecystectomy, this study may help to establish procedures for its use in the emergency setting.

Predictive Value of Antithrombin III and d -Dimer in the Development of Moderate-To-Severe Acute Pancreatitis : A Prospective, Observational Study (AT-PROPANC).

OBJECTIVES: To analyze if antithrombin III (AT-III) and d -dimer levels at admission and at 24 hours can predict acute pancreatitis (AP) progression to moderately severe AP (MSAP) to severe AP (SAP) and to determine their predictive value on the development of necrosis, infected necrosis, organ failure, and mortality. METHODS: Prospective observational study conducted in patients with mild AP in 2 tertiary hospitals (2015-2017). RESULTS: Three hundred forty-six patients with mild AP were included. Forty-four patients (12.7%) evolved to MSAP/SAP. Necrosis was detected in 36 patients (10.4%); in 10 (2.9%), infection was confirmed. Organ failure was recorded in 9 patients (2.6%), all of whom died. Those who progressed to MSAP/SAP showed lower AT-III levels; d -dimer and C-reactive protein (CRP) levels increased. The best individual marker for MSAP/SAP at 24 hours is CRP (area under the curve [AUC], 0.839). Antithrombin III (AUC, 0.641), d -dimer (AUC, 0.783), and creatinine added no benefit compared with CRP alone. Similar results were observed for patients who progressed to necrosis, infected necrosis, and organ failure/death. CONCLUSION: Low AT-III and high d -dimer plasma levels at 24 hours after admission were significantly associated with MSAP/SAP, although their predictive ability was low. C-reactive protein was the best marker tested. CLINICAL STUDY IDENTIFIER: ClinicalTrials.gov NCT02373293.

¿Es precisa la ecografía para el diagnóstico de pólipos vesiculares? Revisión de las piezas de colecistectomía de pacientes diagnosticados de pólipo vesicular durante un periodo de 14 años / Is ultrasonography accurate for the diagnosis of gallbladder polyps? A review of cholecystectomy specimens from patients diagnosed with gallbladder polyps over a 14 years period

Introducción: La incidencia de pólipos vesiculares es del 0,3-12%. Es importante diferenciar los seudopólipos (pólipos de colesterol, adenomiomatosis o pólipos inflamatorios) de los pólipos verdaderos (adenomas y adenocarcinomas). Los principales factores de riesgo de malignización son el tamaño superior a 6-10mm, crecimiento rápido del mismo, morfología sésil, etnia india y colangitis esclerosante primaria. La ecografía es el gold standard para su diagnóstico. Sin embargo, la mayoría de los pólipos diagnosticados por ecografía son seudopólipos. El objetivo del estudio es analizar si la ecografía es precisa para diagnosticar los pólipos verdaderos en los pacientes cuya indicación quirúrgica ha sido este diagnóstico ecográfico. Métodos: Estudio observacional retrospectivo de los pacientes intervenidos en nuestro centro, desde el año 2007 al 2019, de colecistectomía electiva por presentar pólipos vesiculares. La cirugía se indicó en pacientes sintomáticos y/o con factores de riesgo. El estudio fue aprobado por el Comité Ético de Investigación Clínica de nuestro hospital. Resultados: Se han incluido 124 pacientes. En todos ellos se ha realizado colecistectomía laparoscópica. La edad media fue de 55,4 años y el 61% eran mujeres. El 65% tenían síntomas biliares. En nuestro estudio, solo 3 pacientes presentaron pólipos verdaderos (2,4%). Todos ellos, fueron adenomas tubulares. El resto de los pacientes resultaron falsos positivos (97,6%). El tamaño de los adenomas fue de 11, 6 y 5mm. La cirugía se indicó por tamaño o por clínica asociada. Conclusiones: La ecografía no es precisa para el diagnóstico de pólipos vesiculares verdaderos. La validación de otras pruebas complementarias para el diagnóstico de pólipos en pacientes asintomáticos podría ser relevante para evitar cirugías innecesarias. (AU)

Introduction: The incidence of gallbladder polyps is 0,3-12%. It is important to differentiate pseudopolyps (cholesterol polyps, adenomyomatosis, inflammatory polyps), which do not have the potential to become malignant, and true polyps (adenomas and adenocarcinomas). The main risk factors for malignancy are size>6-10mm, rapid growth, sessile morphology, Indian ethnicity and primary sclerosing cholangitis. Ultrasound is the gold standard for diagnosis. However, most polyps diagnosed by ultrasound are pseudopolyps. The main objective of this study is to analyze whether ultrasound is accurate for diagnosing true polyps in patients undergoing surgery for this reason. Methods: We conducted a retrospective observational study with prospective data entry of patients undergoing elective cholecystectomy for gallbladder polyps from 2007 to 2021. Surgery was indicated in symptomatic patients and in those with risk factors. The study was approved by the Clinical Research Ethics Committee of our hospital. Results: Our study included 124 patients who had undergone elective laparoscopic cholecystectomy. Mean age was 55.4 years, and 61% were women. In total, 65% were symptomatic at diagnosis. Only 3 patients had true polyps (2.4%), all of which were tubular adenomas. The remainig patients were false positives (97.6%). The adenoma sizes were 11, 6 and 5mm, respectively. The surgical indication was due to polyp size or due to associated biliary symptoms. Conclusion: Ultrasonography is not accurate for the diagnosis of gallbladder polyps. The validation of other complementary tests for the diagnose gallbladder polyps in asymptomatic patients could be relevant to avoid unnecessary surgeries. (AU)

Complex Procedures in Transanal Endoscopic Microsurgery: Intraperitoneal Entry, Ultra Large Rectal Tumors, High Lesions, and Resection in the Anal Canal.

Transanal endoscopic microsurgery (TEM) allows the local excision of rectal tumors and achieves lower morbidity and mortality rates than total mesorectal excision. TEM can treat lesions up to 18 to 20 cm from the anal verge, obtaining good oncological results in T1 stage cancers and preserving sphincter function. TEM is technically demanding. Large lesions (>5 cm), those with high risk of perforation into the peritoneal cavity, those in the upper rectum or the rectosigmoid junction, and those in the anal canal are specially challenging. Primary suture after peritoneal perforation during TEM is safe and it does not necessarily require the creation of a protective stoma. We recommend closing the wall defect in all cases to avoid the risk of inadvertent perforation. It is important to identify these complex lesions promptly to transfer them to reference centers. This article summarizes complex procedures in TEM.

Aneurisma de la arteria hepática común con compromiso de la arteria esplénica: causa infrecuente de dolor abdominal / No disponible

A common hepatic artery aneurysm with splenic artery involvement: an unusual cause of abdominal pain.

Forty-eight year old man with epigastric pain. CT scan shows a common hepatic artery aneurysm (HAA) of 4,6 cm in size with permeable portal vein. Angiography demonstrates that it affects from the beginning of the celiac trunk until hepatic arteries bifurcation, producing a proximal splenic artery stenosis. Proximal and distal embolization is done achieving a complete aneurysm occlusion. A stent is placed in celiac trunk in order to maintain splenic flow. Permeability of distal hepatic artery through choledochal arteries is observed in a month follow-up CT scan. HAA are infrequent but potentially lethal. Endovascular techniques should be considered of choice currently. HAA embolization has an elevated risk of hepatic ischemia.

Desgaste profesional o burnout en los residentes de Cirugía General. Encuesta de la Asociación Española de Cirujanos / Burnout in General Surgery Residents. Survey From the Spanish Association of Surgeons

INTRODUCCIÓN: El desgaste profesional o burnout afecta significativamente a los médicos y, concretamente, a los cirujanos. El exceso de horas de trabajo, así como la discriminación, abuso y acoso sexual, pueden contribuir al desgaste profesional. Recientemente se ha publicado un estudio sobre este tema en residentes de Estados Unidos que demuestra una elevada incidencia de burnout. El objetivo de nuestro estudio es conocer cuál es la situación en España y compararla con lo que sucede en aquel país. MÉTODOS: Estudio observacional, transversal, efectuado en enero-febrero del 2020, a través de una encuesta validada remitida a todos los residentes de Cirugía General y del Aparato Digestivo (CGAD) de España. RESULTADOS: De los 931 residentes de CGAD, 739 accedieron a la encuesta y 452 (61,2%) la cumplimentaron. En alguna ocasión durante la residencia, el 55,1% de los residentes se han sentido discriminados por su género, el 8,8% por su país de origen, el 73,9% afirman haber experimentado abuso verbal/psicológico, el 7,1% abuso físico y el 16,4% acoso sexual. Los cirujanos adjuntos son la causa más frecuente de acoso sexual, abuso físico y verbal. Los pacientes son el origen más común de la discriminación por género. El 47,6% ha tenido síntomas de desgaste profesional y el 4,6% ha presentado ideas suicidas. El 98% ha excedido su jornada laboral y el 47% no libra las guardias. Estos dos últimos puntos son factores predictivos de desgaste profesional. CONCLUSIONES: Durante el periodo de residencia en nuestro país, los residentes de CGAD han sufrido episodios de maltrato en forma de discriminación, abuso y acoso. Todos los tipos de maltrato son más frecuentes en España que en Estados Unidos, excepto la discriminación racial. Con ello se asocia el incumplimiento significativo en las horas de trabajo semanal. Es necesario reconocer estas anomalías y evitarlas para favorecer un ambiente adecuado para la formación profesional especializada en CGAD

INTRODUCTION: Physicians, especially surgeons, are significatively affected by burnout. Duty-hour violation, as well as discrimination, abuse and sexual harassment may contribute to burnout. A study about this topic has been published in residents from United States, demonstrating a high incidence of burnout. Our objective is to know which is the situation in Spain and to compare it with United States. METHODS: Cross-sectional observational study carried out in January-February 2020, based on the responses to a validated survey administered to General Surgery residents in Spain. RESULTS: There are 931 General Surgery Residents. 739 have entered in the survey and 452 (61.2%) eventually responded to it. In any occasion during the training period, 55.1% reported discrimination based on their gender, 8.8% reported racial discrimination, 73.9% reported verbal/psychological abuse, 7.1% reported physical abuse and 16.4% reported sexual harassment. Attending surgeons are the most frequent source of sexual harassment and physical and verbal abuse, whereas patients are the most frequent cause of gender discrimination. Burnout symptoms were reported by 47.6% of residents and 4.6% reported suicidal thoughts. 98% of residents reported duty-hour violations and 47% of them do not have the day off after to be on call. Both of these issues are burnout predictive factors. CONCLUSIONS: Mistreatment (discrimination, abuse and harassment) occurs among General Surgery residents during their training period in our country. Every kind of mistreatment is more frequent in Spain than in the United States, with the exception of racial discrimination. It is associated with exceeding weekly duty-hour. It is necessary to know these problems and to avoid them in order to improve work environment of General Surgery training period

Botulinum toxin A as an adjunct to giant inguinal hernia reparation.

La toxina botulínica se ha aplicado en la reparación de defectos ventrales, pero la literatura sobre su aplicación en hernias inguinoescrotales es escasa. Presentamos el caso de un paciente con hernia inguinoescrotal gigante. Se realiza tomografía computada basal y otra a las 4 semanas de la administración de toxina botulínica en la musculatura oblicua y en el recto abdominal (reducción de grosor e incremento de longitud de la musculatura). Se repara la pared abdominal mediante la colocación de una malla tipo BioA intraperitoneal y otra tipo DynaMesh® retromuscular. La toxina puede tener un papel importante como adyuvante en la reparación de hernias inguinoescrotales con pérdida de domicilio.Botulinum toxin has been used in ventral defects repair, but literature on its application in inguinoscrotal hernias is scarce. Patient with giant inguinoscrotal hernia. A baseline CT scan is performed and it is repeated four weeks after botulinum toxin injection in oblique musculature and in the abdominal rectum (reduction in thickness and increase in muscle length is observed). The abdominal wall is repaired by placing an intraperitoneal BioA mesh and a retromuscular DynaMesh® mesh. The toxin can have an important role as an adjuvant in the reparation of inguinoscrotal hernias with loss of domain.
