Reoperaciones no programadas en un servicio de cirugía adultos: análisis del protocolo MINSAL / Unscheduled reoperations in adult surgery: analysis of the MINSAL protocol

Resumen Introducción: El análisis de reoperaciones no programadas (RONP) es un indicador de calidad solicitado por el Ministerio de Salud de Chile (MINSAL) desde julio de 2010 como una forma de retroalimentar a los equipos quirúrgicos sobre las causas de reintervenciones en cirugía electiva, promoviendo la discusión técnica en una reunión clínica de pares. Objetivo: Evaluar los resultados de un protocolo de RONP en un hospital público docente de alta complejidad. Materiales y Método: Estudio descriptivo que analiza la base de datos prospectiva iniciada en nuestro centro en julio de 2010 incluyendo todos los pacientes reoperados antes de 30 días desde la intervención inicial electiva. El indicador se consideró cumplido si hubo un análisis crítico del caso antes de 15 días desde la fecha de la reintervención y si hay un documento que lo respalda. Resultados: En el periodo de 9,5 años se efectuaron 18.536 intervenciones electivas con una tasa global de RONP de 2,5%. El protocolo se cumplió en el 97% de los casos. Las RONP representan el 45,5% de la mortalidad global de los equipos estudiados en el periodo. Conclusión: El indicador de las RONP nos parece una práctica relevante en el contexto acotado de un servicio y su evolución en el tiempo. No es útil como indicador global de una institución que involucra servicios de adultos y niños con múltiples especialidades no comparables. Para cumplir con el objetivo debe medirse en forma prospectiva, completa, no discriminatoria y sin carácter punitivo. Teóricamente podría retroalimentar la estrategia quirúrgica de los equipos.

Background: Unplanned reoperations (UPRO) after elective surgery was proposed by Ministry of Health (MINSAL) as a quality indicator since 2010. The goal was to promote the discussion between pairs as an effective feedback for the surgical team. Aim: The purpose of this study is to analyze the results of a protocol of UPRO in a high complexity public institution. Materials and Method: The 9.5 years data base starting in July 2010 was analyzed. All reoperations within 30 days of the initial surgery were included. The UPRO indicator was considered fulfilled if the critical discussion of the case occurred in the clinical meeting within 15 days of the reoperation and if there is a document to support it. Results: in the indicated period the rate of UPRO was 2.5% (455 of 18,536 patients) and the protocol was accomplished in 97% of the cases. The stay in hospital and mortality rate in re-operated patients were high, with great differences between the surgical teams. Conclusions: The UPRO indicator is useful as a detailed analysis of postoperative morbidity of specific surgical teams and the changes along the years. Considering the great differences between the procedures in adults and children and the huge variation and complexity of the operations of multiple surgical specialties, it seems not relevant as a global indicator of a General Hospital. The UPRO must be prospective, complete, non-discriminatory and non-punitive. Theoretically UPRO could be useful as a feedback of surgical teams.

Experiencia del equipo quirúrgico y grado de dificultad de la intervención. ¿Variables significativas en la incidencia de complicaciones durante la cirugía laparoscópica ginecológica? / Experience of the surgical team and level of difficulty of the intervention. Significant variables in the incidence of complications during laparoscopic gynecological surgery?

Resumen OBJETIVO: Primario: observar si el grado de dificultad de la intervención y la experiencia del equipo quirúrgico influyen en la incidencia de complicaciones y consecuencias adversas de la cirugía laparoscópica ginecológica. Secundario: valorar cuál de las dos variables influye de forma más negativa y, además, estudiar los mecanismos que pueden implementarse en la práctica diaria, clínica y formativa para reducir las consecuencias quirúrgicas adversas. MATERIALES Y MÉTODOS: Estudio descriptivo, observacional y retrospectivo efectuado en el Hospital Universitario Virgen Macarena de Sevilla entre enero de 2015 y febrero de 2016. Se incluyeron todas las cirugías laparoscópicas indicadas por diagnóstico de patología benigna. La muestra se dividió en 3 grupos en función de la distribución de los cirujanos y su experiencia quirúrgica. Las intervenciones se categorizaron conforme a la dificultad en tres grados (el 3 correspondió al de mayor dificultad). RESULTADOS: Se incluyeron 195 cirugías laparoscópicas. La experiencia del equipo quirúrgico fue un factor determinante en los desenlaces heterogéneos, por lo que el grado de dificultad de la intervención tuvo una relación más estrecha con las consecuencias quirúrgicas adversas. Por lo que se refiere al grado de dificultad previo a la cirugía, solo fueron estadísticamente significativos el tiempo quirúrgico y la pérdida hemática, que fue mayor en las intervenciones grado 3. La estancia hospitalaria media, las reintervenciones, reingreso, conversión a laparotomía o complicaciones también fueron mayores en el grupo con grado 3 de dificultad y menor en el 1, pero sin significación estadística. CONCLUSIÓN: Con base en lo reportado se desprende que el grado de dificultad de la intervención tiene más influencia en las complicaciones quirúrgicas que la experiencia del cirujano y el ayudante.

Abstract OBJECTIVE: Primary: to observe whether the degree of difficulty of the intervention and the experience of the surgical team influence the incidence of complications and adverse consequences of laparoscopic gynecological surgery. Secondary: to assess which of the two variables influences more negatively and, in addition, to study the mechanisms that can be implemented in daily, clinical and educational practice to reduce the adverse surgical consequences. MATERIALS AND METHODS: Retrospective, observational and descriptive study carried out in the Virgen Macarena University Hospital of Seville, between January 2015 and February 2016. Including all laparoscopic surgeries performed for benign pathology in that period. The sample has been divided into 3 groups according to the distribution of the surgeons, taking into account their surgical experience. On the other hand, the interventions have been categorized according to the difficulty in three levels (with 3 being the most difficult). RESULTS: 195 laparoscopic surgeries have been collected. The experience of the surgical team has been a factor that has shown heterogeneous results, so the level of difficulty of the intervention seems more related to the surgical adverse effects. Regarding the level of difficulty prior to surgery, only surgical time and blood loss were statistically significant, which was greater in level 3 interventions. Variables such as average hospital stay, reoperations, readmission, conversion to laparotomy or complications were also higher in the group of level 3 of difficulty and lower in group 1, but without statistical significance. CONCLUSION: The results raise the theory of which the level of difficulty of the intervention influences of more direct form in the surgical complications that the surgical experience of the surgeon and the assistant.

Identificação e análise das causas responsáveis por reoperações de estrabismo / Identification and analysis of the responsible causes for reoperations of strabismus

RESUMO Introdução: A dificuldade na obtenção de resultados previsíveis é um grande desafio atual da cirurgia corretiva de estrabismo. Os resultados não desejados podem ocorrer em cerca de 51% dos procedimentos e a dificuldade pode ser devida ao fato da cirurgia ser realizada sobre tecidos perioculares bastante moles e com difícil referência para a localização anatômicas das estruturas. Objetivo: Identificar e analisar as principais causas responsáveis por reoperações nos usuários submetidos à cirurgia corretiva de estrabismo, atendidos no Centro de Oftalmológico do HUUFMA, em São Luís-MA. Métodos: Estudo do tipo pesquisa documental retrospectiva dos registros institucionais, por meio da coleta de dados dos prontuários físicos e eletrônicos no sistema ambulatorial interno do HUUFMA. Resultados: A taxa de reoperação analisada foi de 7,31%. Foram operados 89 pacientes menores de 15 anos (72,35%), 23 na faixa de 15 a 30 anos (18,69%) e 11 pacientes maiores de 30 anos (8,94%). A média da idade dos 123 operados foi de 10,32 anos. O sexo feminino foi prevalente na população (58,53%). Conclusão: O desvio Esotrópico (ET) foi o tipo de desvio mais comum no grupo de reoperados. Os resultados inesperados e os maiores desvios foram nos pacientes com relatos de comorbidades e/ou síndromes associadas ao estrabismo, assim como o desvio horizontal congênito (Dhc) foi prevalente entre as queixas apresentadas. A anestesia geral foi mais relatada em pacientes de menor faixa etária. O tempo médio decorrido entre a primeira e a segunda cirurgia foi de 10,54 meses e houve relativa prevalência das subcorreções nas reoperações.

ABSTRACT Introduction: The difficulty in obtaining predictable results is a great challenge on the strabismus surgery field. Procedures can lead to an undesirable development in about 51% of patients, and this difficulty may be due to surgery being perfomed on soft periocular tissues in which anatomical structure can be tricky to locate. Objective: Identify and analyse the main causes of reoperation on strabismus surgery patients treated at Centro Oftamológico do HUUFMA, in São Luís-MA. Methods: A retrospective documental research based on institutional registries, through data collection from physical and eletronic patient records of HUUFMA's ambulatorial internal system. Results: The analysed reoperation rates were in about 7,31%. 89 patients under 15-year-old (72,35%), 23 patients aged between 15 to 30 (18,69%), and 11 patients over the age of 30 (8,94%) were submitted to surgery, with total number of 123 patients and mean age of 10,32 years. Female patients have prevailed in the population (58,53%). Conclusion: Esotropic deviation was the most common deviation in the reoperated group. The unexpected results and greatest deviations occurred on patients with reported comorbidities and/or syndromes associated with strabismus, such as dissociated horizontal deviation (DHD), which was prevalent among the presented complaints. General anesthesia was most reported in lower age patients. The average time elapsed between the first and the second procedure was 10,54 months, and a relative prevalence of the undercorrections occurred on reoperations procedures.

Detención de la hemorragia uterina anormal en pacientes a quienes se realizó histeroscopia operatoria / Resolution of abnormal uterine hemorrhage in patients submitted to operational histeroscopy in the University Hospital of Santander

Resumen OBJETIVO: Evaluar los factores sociodemográficos, clínicos, histopatológicos y del procedimiento quirúrgico asociados con el control (satisfactorio o inadecuado) de la hemorragia uterina anormal de pacientes a quienes se realizó histeroscopia operatoria. MATERIALES Y MÉTODOS: Estudio de casos y controles anidado en una cohorte retrospectiva al que se incluyeron pacientes que consultaron por hemorragia uterina anormal en el Hospital Universitario de Santander, Colombia (2008-2014). Variables independientes: factores demográficos, antecedentes clínicos, quirúrgicos y posquirúrgicos. RESULTADOS: Se encontraron registros de 180 procedimientos de histeroscopia; 124 de histeroscopias operatorias, de las que 114 se practicaron debido a síntomas de hemorragia uterina anormal; de estas últimas, 22 fueron reintervenciones para controlar la hemorragia uterina anormal (casos) y 92 controles. Los límites de edad se ubicaron en 19 y 66 años, con una mediana de 39 años; la mayoría eran menores de 45 años (66.7%), edad que se asoció como factor protector. El porcentaje de complicaciones durante el procedimiento fue de 1.75%, relacionadas con perforación uterina. Solo dos pacientes tuvieron complicaciones posquirúrgicas y la reintervención quirúrgica tuvo una incidencia de 19.3%; es decir, sucedió en 22 pacientes. CONCLUSIÓN: El riesgo de reintervención está relacionado con la hiperplasia endometrial, edad mayor de 45 años, antecedente de discrasia sanguínea y localización de la lesión en áreas diferentes al cuello uterino y como variable protectora el antecedente de paridad. Se hizo evidente la relación entre la falla del procedimiento histeroscópico, las variables de hiperplasia endometrial y la discrasia sanguínea.

Abstract OBJECTIVE: To evaluate the sociodemographic, clinical, histopathological and surgical procedure factors associated with the control (satisfactory or inadequate) of abnormal uterine hemorrhage in patients who underwent operative hysteroscopy. MATERIALS AND METHODS: Nested case-control study in a retrospective cohort that included women who consulted for abnormal uterine hemorrhage at the University Hospital of Santander, Colombia, from 2008 to 2014. Independent variables: demographic factors, clinical history, surgical and postsurgical. RESULTS: Records of 180 hysteroscopy procedures were found; 124 of operative hysteroscopies, of which 114 were performed due to symptoms of abnormal uterine hemorrhage; of the latter, 22 were reoperations to control abnormal uterine hemorrhage (cases) and 92 controls. The age limits were located in 19 and 66 years, with a median of 39 years; the majority were under 45 years old (66.7%), an age that was associated as a protective factor. The percentage of complications during the procedure was 1.75%, related to uterine perforation. Only two patients had postoperative complications and the surgical reoperation had an incidence of 19.3%; that is, it happened in 22 patients. CONCLUSION: The risk of reoperation is related to endometrial hyperplasia, age over 45 years, history of blood dyscrasia and location of the lesion in areas other than the cervix, and as a protective variable, the antecedent of parity. The relationship between the failure of the hysteroscopic procedure, the variables of endometrial hyperplasia and blood dyscrasia was evident.

Late reoperations after repaired Stanford type A aortic dissection / 中华外科杂志

Objective@#To summarize the experience of reoperations on patients who had late complications related to previous aortic surgery for Stanford type A dissection.@*Methods@#From August 2008 to October 2016, 14 patients (10 male and 4 female patients) who underwent previous cardiac surgery for Stanford type A aortic dissection accepted reoperations on the late complications at Department of Thoracic and Cardiovascular Surgery, Nanjing Hospital Affiliated to Nanjing Medical University. The range of age was from 41 to 76 years, the mean age was (57±12) years. In these patients, first time operations were ascending aorta replacement procedure in 3 patients, ascending aorta combined with partial aortic arch replacement in 4 patients, aortic root replacement (Bentall) associated with Marfan syndrome in 3 patients, aortic valve combined with ascending aorta replacement (Wheat) in 1 patient, ascending aorta combined with Sun′s procedure in 1 patient, Wheat combined with Sun′s procedure in 1 patient, Bentall combined with Sun′s procedure in 1 patient. The interval between two operations averaged 0.3 to 10.0 years with a mean of (4.8±3.1) years. The reasons for reoperations included part anastomotic split, aortic valve insufficiency, false aneurysm formation, enlargement of remant aortal and false cavity. The selection of reoperation included anastomotic repair, aortic valve replacement, total arch replacement and Sun′s procedure.@*Results@#Of the 14 patients, the cardiopulmonary bypass times were 107 to 409 minutes with a mean of (204±51) minutes, cross clamp times were 60 to 212 minutes with a mean of (108±35) minutes, selective cerebral perfusion times were 16 to 38 minutes with a mean of (21±11) minutes. All patients survived from the operation, one patient died from severe pulmonary infection 50 days after operation. Three patients had postoperative complications, including acute renal failure of 2 patients and pulmonary infection of 1 patient, and these patients were recovered after treatment. Thirteen patients were finally recovered from hospital. The patients were followed up for 16 to 45 months, and no aortic rupture, paraplegia and death were observed in the follow-up.@*Conclusions@#Patients for residual aortic dissection after initial operations on Stanford type A aortic dissection should be attached great importance and always need emergency surgery, but the technique is demanding and risk is great for surgeons and patients, which need enough specification and accurate on aortic operation. More importantly, the Sun′s procedure also should be performed on the treatment of residual aortic dissection or distal arch expansion, and obtains the short- and long-term results in the future.

A Clinical Analysis of Intermittent Exotropia Patients Requiring More than Three Reoperations

PURPOSE: To evaluate the clinical analysis of intermittent exotropia patients who required more than three reoperations and to investigate the factors leading to situations that require more than three reoperations. METHODS: We retrospectively analyzed the results of 13 patients who underwent more than three reoperations for recurrence after the second operation, as well as for 29 patients who had successful results for operation at least 1 year after the second operation. We investigated the factors associated with surgical outcomes of the second operation using multiple logistic regression analysis, which included; onset of symptom, primary, secondary, tertiary, and fourth ages of surgery, stereopsis before and after surgery, distance and near deviation before and after surgery, and constancy of exotropia. RESULTS: There were more cases in which symptoms occurred before 1 year of age (p = 0.011) and which had constant exotropia (p = 0.023), with a large deviation at first operation (p = 0.003) after more than three operations compared to patients who only had two operations. There were less cases that achieved initial overcorrection after first operation (p = 0.003) and successful postoperative stereopsis after second operation (p = 0.043) in the three operations group than in the two operations group. Among these factors, the most important factor affecting reoperation and success after second operation was related to successful recovery of stereopsis using multiple regression analysis (odds ratio [OR] = 50.00, 95% confidence interval [CI] = 4.392–569.224, p = 0.002). CONCLUSIONS: In cases of intermittent exotropia occurring before 1 year of age, constant exotropia with a large deviation at first operation, and insufficient initial overcorrection after operation, it may be necessary for patients to receive more than three operations because of recurrence. Further, recovery of postoperative stereopsis after the second operation was the most important predictor for postoperative results.

Reoperations Following Cervical Disc Replacement

Cervical disc replacement (CDR) has emerged as an alternative surgical option to cervical arthrodesis. With increasing numbers of patients and longer follow-ups, complications related to the device and/or aging spine are growing, leaving us with a new challenge in the management and surgical revision of CDR. The purpose of this study is to review the current literature regarding reoperations following CDR and to discuss about the approaches and solutions for the current and future potential complications associated with CDR. The published rates of reoperation (mean, 1.0%; range, 0%-3.1%), revision (mean, 0.2%; range, 0%-0.5%), and removal (mean, 1.2%; range, 0%-1.9%) following CDR are low and comparable to the published rates of reoperation (mean, 1.7%; range; 0%-3.4%), revision (mean, 1.5%; range, 0%-4.7%), and removal (mean, 2.0%; range, 0%-3.4%) following cervical arthrodesis. The surgical interventions following CDR range from the repositioning to explantation followed by fusion or the reimplantation to posterior foraminotomy or fusion. Strict patient selection, careful preoperative radiographic review and surgical planning, as well as surgical technique may reduce adverse events and the need for future intervention. Minimal literature and no guidelines exist for the approaches and techniques in revision and for the removal of implants following CDR. Adherence to strict indications and precise surgical technique may reduce the number of reoperations, revisions, and removals following CDR. Long-term follow-up studies are needed, assessing the implant survivorship and its effect on the revision and removal rates.

Factores predictivos de reintervención en cirugía colorrectal laparoscópica / Predictive factors for reoperation after colorrectal laparoscopic surgery

Introducción: son varios los criterios que se han propuesto para determinar los factores predictivos de complicaciones en cirugía colorrectal laparoscópica. Objetivo: identificar los posibles factores predictores de reintervención después de cirugía colorrectal laparoscópica. Métodos: se revisaron las historias clínicas de los pacientes reintervenidos por complicaciones después de cirugía colorrectal laparoscópica en el Centro Nacional de Cirugía de Mínimo Acceso (CNCMA), en el período comprendido de enero de 2007 a diciembre de 2011. A través de un modelo de regresión logística, se estudió la asociación entre la reintervención y las siguientes variables independientes: edad, sexo, enfermedad de base (indicación quirúrgica), tiempo quirúrgico, tipo de anastomosis, tipo de sutura mecánica. Se consideró estadísticamente significativo un valor p < 0,05. Resultados: se reintervinieron 27 pacientes de 330 operados. La técnica quirúrgica (Dixon bajo) y el tipo de anastomosis (extracorpórea) fueron las variables que se asociaron de manera estadísticamente significativa con la presencia de reintervención en la cirugía colorrectal. Conclusiones: la técnica quirúrgica (Dixon bajo) y el tipo de anastomosis (extracorpórea) son posibles factores predictivos de reintervención en los operados de enfermedades colorrectales por vía laparoscópica(AU)

Introduction: numerous criteria have been stated in order to determine predictive factor for laparoscopic colorectal surgery. Objective: to identify possible predictive factors for reoperation after laparoscopic colorectal surgery. Methods: the medical records of re-operated patients due to complications after laparoscopic colorectal surgery at the National Center of Minimal Access Surgery were checked from January 2007 to December 2011. A logistic regression model allowed analyzing the association between reoperation and the following independent variables: age, gender, underlying disease (surgery indications), surgical time, type of anastomosis, type of mechanical suture. The statistically significant value of p< 0.05 was taken. Results:twenty seven out of 330 patients with laparoscopic colorectal surgery were re-operated. The surgical procedure (low Dixon) and type of anastomosis (extracorporeal) showed statistically significant association with reoperation after laparoscopic colorectal surgery. Conclusions: the surgical procedure (low Dixon) and type of anastomosis (extracorporeal) were possible predictive factors for re-operation after laparoscopic colorectal surgery(AU)

Orquidopexia videoasistida (OVA): ¿es la técnica de elección para una criptorquidia palpable difícil? / Video-Assisted orchidopexy (OVA): is it the technique of choice for difficult palpable undescended testicles?

Existe un grupo de pacientes con criptorquidias palpables en los que la liberación de los vasos espermáticos y el conducto deferente en el retroperitoneo por laparoscopía, facilitaría la orquidopexia abierta en un sólo tiempo y mejoraría el pronóstico de posición y vitalidad testicular a largo plazo. Presentamos nuestra experiencia inicial de pacientes tratados con esta técnica, a la que hemos denominado Orquidopexia Video Asistida (OVA).Estudio prospectivo entre agosto de 2011 y marzo de 2012 que incluyó 15 pacientes y 16 testículos. Se incluyeron criptorquidias canaliculares altas, “peeping testis” y re-operaciones. Se excluyeron pacientes que, en el examen bajo anestesia general, se palpó testículo en posición canalicular media o baja. En 8 meses se realizaron 9 OVA izquierdas, 5 derechas y 1 bilateral. La edad operatoria promedio de los pacientes fue de 3,7 años. El tiempo quirúrgico promedio fue de 55 minutos. El tiempo de seguimiento promedio fue de 9 meses (r6-14 meses). El seguimiento clínico ha mostrado posición normal y buena vitalidad testicular evaluada por tamaño testicular al examen físico en todos los pacientes. CONCLUSIONES: Los resultados clínicos preliminares son alentadores. Proponemos agregar OVA al algoritmo de tratamiento de las criptorquidias palpables.

There is a group of patients with palpable cryptorchidism in which releasing the spermatic vessels and the vas deferens in the retroperitoneum through laparoscopy, facilitates the open orquidopexy in a single time and improves the prognosis of testicular position and vitality on the long term. We report our initial experience of patients treated with this technique, which we called Video Assisted orchidopexy (OVA).Prospective study between August 2011 and March 2012, which included 15 patients and 16 testicles. High canalicular cryptorchidism, “peeping testis” and re-operations were included. We excluded patients who, on examination under general anesthesia, had a palpable canalicular testis in middle or low position. RESULTS: In a peroid of 8 months we performed 9 left, 5 right and 1 bilateral OVA. Mean age of the patients was 3.7 years. Mean operative time was 55 minutes. Average follow-up time was 9 months (r6-14 months). Clinical follow-up shows normal position and good vitality as assessed by testicular size at physical examination on all patients. Preliminary clinical results are encouraging. We propose adding OVA treatment algorithm palpable cryptorchidism.

Two Successful Proximal Reoperation Cases after Acute Type A Dissection Repair / 日本心臓血管外科学会雑誌

We report 2 cases of successful proximal reoperations after acute type A dissection. Case 1 : A 53-year-old man underwent ascending aorta and aortic arch replacement and aortic valve re-suspension for acute type A dissection with aortic valve regurgitation in 1992. Thirteen years after the first operation, computed tomography demonstrated a Valsalva aneurysm (74 mm) and Doppler echocardiography showed moderate aortic valve regurgitation. Therefore, we performed an operation. We could not locate the dissection in the Valsalva sinus, and the aortic valve cusps had organic change. A David procedure was performed. The postoperative course was uneventful and he was discharged on the 19th postoperative day. Case 2 : A 65-year-old woman underwent ascending aorta replacement and aortic valve resuspension for acute type A dissection with aortic valve regurgitation in 1997, but 11 years after the first operation, computed tomography demonstrated a Valsalva aneurysm (55 mm) and arch aneurysm (65 mm) with stenosis of the innominate vein and she had facial and left arm edema. Doppler echocardiography showed moderate aortic valve regurgitation. We could not find the location of dissection in the Valsalva sinus or aortic arch, and aortic valve cusps had no organic change. A Bentall procedure and total arch replacement were performed and her postoperative course was uneventful.

Surveillance & management of out-of-plan re-operations / 中华医院管理杂志

A series of surveillance and management actions was taken to minimize out-of-plan re-operations. These actions include: 1) Building and completing the surveillance and management mechanism against unplanned re-operations; 2) Building a real-time surveillance and reporting mechanism; 3) Enhancing quality control and continuous improvement at the operating departments; 4) Enhancing the supervision on regulations implementation by quality control departments of the hospital; 5) Enhancing quality control for medical records; 6) Building a feedback mechanism for surveillance results; 7) Building a penalty and reward mechanism. Efforts for one year and a half on such surveillance and management proved successful, as the incidence of out-of-plan re-operations fell from 1.7% before these actions to 1.0% afterwards.
