Survival Analysis and Prognostic Factors for Peri-ocular Malignancies in Malaysia

@#Introduction: This study aims to determine the prognostic factors and survival outcomes of patients that underwent this surgery. Method: A retrospective review of 43 patients who underwent exenteration for periocular malignancies over a 14-year period was carried out. Patient demographics, tumour histology, treatment details, surgical margins’ status and post-operative survival were recorded. The survival outcome examined was the overall survival (OS) rate. Cox regression and Kaplan-Meier analysis were used to evaluate post-exenteration survival. Results: In total, 20 females and 23 males with a median age of 62 ± 17.3 years were identified. The most common indication for exenteration was basal cell carcinoma (20.9%), followed by squamous cell carcinoma (18.6%), adenocystic carcinoma (14%), malignant melanoma (14%) and sebaceous gland carcinoma (11.6%). The independent predictors for worse OS on multivariate analysis were Chinese ethnicity (adjusted hazard ratio [aHR] 4.95, p =0.017), sebaceous gland carcinoma (aHR 57.61 p=0.006), adenocystic carcinoma (aHR 45.87, p=0.008), clear surgical margins (aHR 5.41, p=0.025), receiving only chemotherapy (aHR 169.13, p=0.004), and receiving both adjuvant chemotherapy and radiotherapy (aHR 41.51, p=0.010). Conclusion: We recommend targeted public health initiatives for Chinese patients due to their increased mortality risk from peri-ocular malignancies. In addition, we advise comprehensive adjuvant therapy for all patients regardless of whether a clear surgical margin is achieved. Basal cell carcinoma and adenocystic carcinoma may also benefit from genetic research. We advocate more training for ophthalmologists to identify periocular malignancies earlier for better treatment options and increased chances of survival.

Cross-sectional study to describe the severity, bio-chemical associations, and final outcomes of COVID-19-associated rhino-orbital-cerebral mucormycosis in a tertiary hospital of East India

Purpose: The second wave of coronavirus disease 2019 (COVID?19) pandemic triggered a mucormycosis epidemic in India. Diabetes mellitus and dysregulated immune response were contributors, and rhino?orbital?cerebral mucormycosis (ROCM) was the most common presentation. It is however not known whether bio?chemical parameters at presentation correlate with stage of ROCM or final outcome in terms of vision or mortality. Methods: This retrospective, hospital?based study included all in?patients of mucormycosis with ophthalmic manifestations at presentation admitted during June 1, 2021 to August 31, 2021. It aimed to evaluate the association between severity of infection, serum levels of HbA1c, ferritin, interleukin?6 (IL?6), C?reactive protein (CRP), and D?dimer levels at presentation and outcome. Results: There were altogether 47 eligible cases having a mean age of 48.8 ± 10.9 years with a male:female ratio of 2.6:1; forty?two (89.4%) had pre?existing diabetes, and five (10.6%) had steroid?induced hyperglycemia. The mean HbA1c among diabetics was 9.7 ± 2.1. HbA1c and serum CRP showed an increase over subsequent stages, which was not statistically significant (P = 0.31). IL?6 values for all stages were similar (P = 0.97). Only serum ferritin levels showed a statistically significant increase over stages (P = 0.04). IL?6 was significantly lower (P = 0.03) in patients who survived, whereas CRP levels were significantly lower in patients who had final visual acuity (VA) better than only perception of light (P = 0.03). Conclusion: Uncontrolled diabetes mellitus is a significant association of ROCM. Serum ferritin levels at presentation best correlate with extent of the disease. CRP levels are best to prognosticate cases that will have sufficient VA to carry on activities of daily living, whereas IL?6 levels are best associated with survival

Exploring the globe salvaging treatment options in patients of COVID-19-associated mucormycosis with orbital involvement

Purpose: To explore the various globe salvaging treatment strategies for patients with coronavirus disease 2019?associated mucormycosis (CAM). Methods: This was a prospective interventional analytical study conducted at a Medical College in rural India. A total of 84 patients of CAM admitted between May 2021 and August 2021 were enrolled for the study. Patients with histologically proven CAM with clinical and/or radiological evidence of orbital involvement were divided into three treatment categories based on the site and extent of the lesion. Re?assessment was performed after 7 days. For patients who worsened with the primary approach, orbital exenteration was considered based on a Sion Hospital Scoring System. A novel approach to intra?orbital anti?fungal therapy, site?centered peri?bulbar injection of amphotericin B (SCPeriAmB), was also explored. All the patients were followed up for at least 3 months. Convenience sampling with descriptive statistics was used. Results: Six patients had to finally undergo exenteration by the end of the study period. The rest of the patients were reported to be stable or improved. No mortalities were reported on delaying the exenteration. No adverse events were noted in patients who were given SCPeriAmB. Conclusion: Globe salvaging treatment options should be advocated as a primary approach in patients with CAM. Site?centered peri?bulbar injections can be considered as an approach for delivering intra?orbital anti?fungal therapy in selected patients

Demographic and Clinical Profile of Patients Presenting with COVID-19-Associated Rhino-orbito-cerebral Mucormycosis at a Tertiary Care Center

Objectives?Individuals affected with rhino-orbito-cerebral mucormycosis (ROCM) associated with coronavirus disease 2019 (COVID-19) increased enormously in northern India during the second wave of the novel coronavirus disease. This study determined the demographic and clinical profile including the risk factors in patients presenting to a tertiary care hospital in northern India. Materials and Methods?This is a descriptive study involving patients admitted with COVID-19-associated ROCM and were managed from May 2021 to 20th July 2021. Statistical Analysis?The data was analyzed using SPSS (IBM SPSS Statistics 20, SPSS Inc., Chicago, Illinois, United States) software and Microsoft Excel (Version 16.49). The chi-squared and Fisher's exact tests were used to compare various outcomes. A p-value of less than or equal to 0.05 was considered to be statistically significant. Results?One hundred and seventeen (117) patients (males: 70 [59.8%], females:47 [40.2%]) with the average age of 51.85?±?12.80 years presented with orbital involvement. Diabetes mellitus was noted in 100 (86.2%) patients. Of the available data from the records, oxygen supplementation for the management of COVID-19 was received by 37/108 (34.3%) patients for a median average duration of 11 days. Forty-eight patients of one-hundred-seventeen (60%) patients were treated with corticosteroids with a median duration of steroid administration being 10 days. The duration between onset of symptoms related to mucormycosis and diagnosis of COVID-19 was 0 to 75 days for 48 patients. Intravenous amphotericin B was administered in all cases. External sinonasal debridement was performed in 90 of 114 (78.9%) patients, retrobulbar amphotericin B injection was administered in 56 of 117 (47.9%), and orbital exenteration was performed in 17 of 117 (14.5%) of cases. Conclusion?Administration of corticosteroids and diabetes mellitus seem to be the major underlying causes for the development of COVID-19-associated ROCM. Prompt diagnosis and multidisciplinary management approach are essential for a reduction in mortality.

Treatment Strategies of Orbit in Sinonasal Malignancy Patients with Orbital Invasion / 肿瘤防治研究

Due to the paranasal sinuses adjacent to the orbit, the sinonasal malignancy is prone to invade the orbit, which is not only the advanced stage of the tumor, but also one of the poor prognostic factors. Preoperative CT and MRI scan and intraoperative frozen section analysis are used to evaluate the orbital invasion of the tumor. Orbital preservation is adopted if the periorbita is not transgressed by tumor. Orbital preservation can be considered if the tumor invades the periorbita and extraconal fat in a limited range, responds well to neoadjuvant chemotherapy, radiotherapy or other multimodality treatment, or has a negative section margin. Orbital exenteration is performed if the tumor extensively invades the periorbita, and invades the extraocular muscle, eyeball and orbital apex. Whether orbital preservation or orbital exenteration is adopted, it should be evaluated and made decision by a multidisciplinary team, and fully communicate with the patient.

Prosthetic Rehabilitation Technique with an Economical Customized Orbital Prosthesis

@#Post-surgical orbital defects pose a severe effect on patient, psychologically and physically, especially in the eventual return to the society and daily routine. In cases where reconstructive surgery is not possible, prosthetic rehabilitation is crucial in addressing this issue. Implant-supported orbital prosthesis provides superior retention, however, it is not economically acceptable for some cases. Various modes of retention are available to cater to each patient’s diagnosis, treatment need and economical status. This article describes the procedures in the construction of a customized silicone orbital prosthesis using adhesive and spectacles for retention. This technique is cost-effective and simple while providing comfort and satisfaction for the patient.

Double barreled wet colostomy. Case report and description of the surgical technique / Colostomia úmida em dupla-boca. Relato de caso e descrição da técnicacirúrgica

ABSTRACT Pelvic exenteration has showed to be beneficial therapeutically and palliatively in locally advanced colorectal cancer. Reconstruction of urinary transit posterior to a cystectomy has always been challenging with many associated complications. We present a 58-year-old male with locally advanced rectal cancer in which a pelvic exenteration and a double-barreled wet colostomy (DBWC) was created for urinary reconstitution. We present the surgical technique of DBWC. DBWC is a good alternative to other urinary reconstructions because fecal and urinary derivation occurs in only one stoma, the stoma output is easier to manage, and fewer complications are seen compared to other urinary reconstructions. Long-term surveillance is mandatory in patients with a DBWC because there is an increased risk of neoplasm in the reservoir.

RESUMO A exenteração pélvica mostrou-se benéfica, tanto terapêutica quanto paliativamente, em casos de câncer colorretal localmente avançado. A reconstrução do trânsito urinário após uma cistectomia sempre foi desafiadora, com muitas complicações associadas. Os autores apresentam o caso de um homem de 58 anos de idade com câncer retal localmente avançado, submetido a uma exenteração pélvica e uma colostomia úmida em dupla-boca (CUDB) para reconstituição urinária. Os autores apresentam a técnica cirúrgica da CUDB, uma boa alternativa para outras reconstruções urinárias, já que a derivação fecal e urinária ocorre em apenas um estoma, a saída do estoma é mais fácil de gerenciar e o método apresenta menos complicações em comparação com outras reconstruções urinárias. A vigilância a longo prazo é obrigatória em pacientes com CUDB, pois há um risco aumentado de neoplasia no reservatório.

Análise do manejo cirúrgico de pacientes com câncer cervical recidivado após radioterapia e quimioterapia / Analysis of the surgical management of patients with recurrent cervical cancer after radiotherapy and chemotherapy

RESUMO Objetivos: Analisar os resultados de morbidade e sobrevida após cirurgias curativas e paliativas em pacientes com câncer cervical recidivado após tratamento primário com radioterapia e quimioterapia. Outro objetivo foi avaliar os fatores associados aos procedimentos curativos e não curativos. Métodos: Coorte retrospectiva de pacientes submetidos à cirurgias curativas e paliativas, entre janeiro de 2011 a dezembro de 2017, em um centro de alta complexidade em oncolologia. O desfecho da morbidade foi relatado de acordo com a classificação de Clavien-Dindo e a análise de sobrevida foi realizada pelo método de Kaplan-Meir. Para avaliar os fatores associados aos procedimentos, foi realizada análise univariada pelo teste U de Mann-Whitney. Resultados: Foram realizadas duas histerectomias radicais, três exenterações pélvicas com intenção curativa e cinco exenterações pélvicas paliativas. No grupo curativo, houve complicações maiores em 40% dos casos, e o tempo mediano de sobrevida foi 16 meses. No grupo paliativo, houve complicações maiores em 60% dos casos, e o tempo mediano de sobrevida foi 5 meses. Estadiamento avançado (p=0,02), sintomas (p=0,04), tamanho do tumor maior que cinco centímetros (p=0,04) e mais de três órgãos envolvidos (p=0,003) foram fatores significativamente associados a cirurgia não curativa. Conclusões: As taxas de morbidade foram maiores no grupo paliativo, e o tempo mediano de sobrevida foi menor no grupo paliativo do que no grupo curativo, entretanto esta diferença na sobrevida não teve significância estatística. Estádio avançado, sintomas, tamanho tumoral e número de órgãos envolvidos são fatores que devem ser levados em consideração na indicação de resgate cirúrgico.

ABSTRACT Objectives: To analyze the results of morbidity and survival after curative and palliative surgery in recurrent cervical cancer patients who underwent chemoradiation as their primary treatment. Another goal was to assess the factors associated with curative and non-curative procedures. Methods: This was a retrospective cohort consisting of patients undergoing surgery curative and palliative from January 2011 to December 2017 at a high complexity oncology center. Outcome of morbidity was reported according to the Clavien-Dindo classification, and survival analysis was carried out using the Kaplan-Meir method. To assess the factors associated with the procedures, a univariate analysis using the Mann-Whitney U test was performed. Results: Two radical hysterectomies, three pelvic exenterations with curative intent, and five palliatives pelvic exenterations were performed. In the curative group, there were major complications in 40% of the cases, and the median survival time was 16 months. In the palliative group, there were major complications in 60% of the cases, and the median survival time was 5 months. Advanced staging (p-value= 0.02), symptoms (p-value=0.04), tumor size greater than five centimeters (p-value=0.04), and more than three organs involved (p-value=0.003) were factors significantly associated with non-curative surgery. Conclusions: The morbidity rates of this study were higher in palliative group, and the median survival time was lower in the palliative group than the curative group, but this difference in survival was not statistically significant. Advanced stage, symptoms, tumor size and number of organs involved are factors that should be taken into consideration when indicating surgical salvage.

Rehabilitation of an Orbital Defect with Silicone Orbital Prosthesis: A Case Report

Introduction: Loss of eye, apart from impaired vision has adetrimental effect on psychosocial wellbeing of an individual.The replacement of the lost eye as soon as possible after thesurgery is necessary to improve social acceptance and qualityof life. Multidisciplinary management and team approachbetween surgeon and prosthodontist are essential in providingaccurate and effective rehabilitation and follow-up care for thepatient.Case report: This case report describes a simplified methodfor the fabrication of a custom silicone orbital prosthesisretained with spectacles for rehabilitation of a residual defectpost exenteration of left eye. It highlights the importance ofindepth analysis & comparison of the defect with the normalcontralateral eye which was used as an anatomical guide forfabrication of an aesthetic prosthesis.Conclusion: Advanced digital technology like rapidprototyping and CAD/CAM have made fabrication ofcomplex prosthesis like orbital prosthesis simpler andquicker. However, these contemporary methods are techniquesensitive, equipment dependent and may not be availableeasily. Thus, a maxillofacial prosthodontist should be able toread the available anatomical guides and use them to fabricatean aesthetically acceptable prosthesis using conventionaltechnique to rehabilitate patients and improving quality of lifeas soon as possible.

Tratamiento quirúrgico en las etapas de desarrollo del carcinoma ocular de células escamosas en bovinos del trópico alto del departamento de Nariño / Surgical treatment in the development stages of bovine ocular squamous cell carcinoma in the high tropic of Nariño department / Tratamento cirúrgico nas fases de desenvolvimento do carcinoma ocular de células escamosas em bovinos dos trópicos superiores do departamento de Nariño

Resumen El carcinoma ocular de células escamosas (COCE) es una de las neoplasias oculares más común en bovinos. Este estudio evaluó el tratamiento quirúrgico en los estadios 1, 2, 3 y 4. La ubicación del COCE fue en el limbo esclerocórneal, párpados, córnea y en la membrana nictitante. Para cada caso clínico se realizó una técnica de bloqueo y quirúrgica. En todos los casos se administró una dosis de sedación que mantuviera el animal en pie, utilizando Xilazina 2%, dosis de 0,015- 0,03 mg/kg IV en vena coccígea. En los casos de COCE en tercer párpado se bloqueó el nervio auriculopalpebral, zigomático e intratroclear, en casos de párpados y conjuntiva dependiendo del sitio se bloqueaba determinado nervio. Para la exenteración orbital, se bloqueó con los cuatro puntos y el retrobulbar administrando 10-15 cc de lidocaína al 2%. En casos de COCE en la cuarta etapa donde está involucrado el globo ocular y tejidos adyacentes, se realizó exenteración orbital. En cárcinoma de la membrana nictitante, se realizó la resección de esta en su totalidad, en la córnea, se realizó una queratectomia superficial y en el párpado inferior, la blefaroplastia. Se intervinieron quirúrgicamente 25 vacas, de raza Holstein, Normando, Holstein x Simental y Montbeliarde. La membrana nictitante fue extirpada en 14 casos, exenteración orbital en 9, queratectomía superficial y blefaroplastia en el párpado inferior en un solo caso, respectivamente. Se presentó recidiva en dos casos las cuales fueron descartadas. El tratamiento quirúrgico temprano ayuda como control del COCE permitiendo que los animales sigan en el hato durante su vida productiva.

Abstract Squamous ocular cell ocular carcinoma (SOCC) is one of the most common and important ocular neoplasms of frequent occurrence in cattle. The objec- tive of the work was to evaluate the surgical treatment in stages 1, 2, 3 and 4. Four presentations of the SOCC were evidenced; in the sclerocórneal limb, eyelids, córnea and in the nictitating membrane. For each clinical case, a blocking and surgical technique was performed. In all cases, a sedation dose was administered to keep the animal standing, using 2% Xylazine, a dose of 0.015-0.03 mg/kg IV in the coccygeal vein. In cases of SOCC in the third eye- lid, the atriopalpebral, zygomatic and intratrochlear nerves were blocked, in cases of eyelids and conjunctiva depending on the site, the correspon- ding nerve was blocked. For orbital exenteration, in addition to the blockage of the four points, it is anesthetized behind the eyeball with the retrobulbar technique, administering 10-15 cc of 2% lidocaine. In cases of SOCC in the fourth stage where the eyeball and adjacent tissues are involved, orbital exenteration was performed. The carcinoma on the nictitating membrane, resection was performed, in the córnea, a superficial keratectomy and in the lower eyelid, a blepharoplasty. Twenty-five cows, Holstein, Normando, Holstein x Simental and Montbeliarde were surgically treated. The nictitating membrane was removed in 14 cases, orbital exenteration in nine, superficial keratectomy and blepharoplasty in inferior eyelid in a single case respectively. Recurrence occurred in two cases that were culled. Early surgical treatment helps control SOCC allowing animals to remain in the herd during their pro- ductive life.

Em todos os casos, foi administrada uma dose de sedação para manter o animal em pé, usando Xilazina a 2%, uma dose de 0,015-0,03 mg/kg IV na veia coccígea. Nos casos de COCE na terceira pálpebra, o nervo atriopalpebral, zigomático e intratroclear foi bloqueado; nos casos de pálpebras e conjuntiva, dependendo do local, um determinado nervo foi bloqueado. Para exenteração orbital, foi bloqueado com os quatro pontos e o retrobulbar, administrando 10-15 cc de lidocaína a 2%. Nos casos de COCE no quarto estágio em que o globo ocular e os teci- dos adjacentes estão envolvidos, foi realizada exenteração orbital. No carcinoma da membrana nictitante, foi realizada ressecção do todo; na córnea, foi realizada uma ceratectomia superficial e, na pálpebra inferior, blefaroplastia. Vinte e cinco vacas, Holstein, Normando, Holstein x Simental e Montbeliarde foram operadas cirurgicamente. A membrana nictitante foi removida em 14 casos, exenteração orbital em 9, ceratectomia superficial e blefaroplastia na pálpebra inferior em um único caso, respectivamente. A recorrência ocorreu em dois casos que foram descartados. O tratamento cirúrgico precoce ajuda a controlar o COCE, permitindo que os animais permaneçam no rebanho durante sua vida produtiva.

Rehabilitation of Exenterated Right Eye: A Prosthetic Challenge

Background: Facial defects can be acquired or congenital, but irrespective of etiology, any maxillofacial structure if damaged or missing will result in an unaesthetic and unappealing personality of individual. Orbital defects are very evident and effect the appearance and social front of the individual. Many modalities are available to rehabilitate the defect of an orbit but prosthetic rehabilitation with silicone prosthesis is a simple and effective approach. Retention is generally achieved by engaging available undercuts or using mechanical accessories or skin adhesives etc. This case report describes successful rehabilitation of right orbital defect using a non-surgical approach with room temperature vulcanized silicone and skin adhesives. Case Report: A 45 yr old male reported with, chief complaint of missing right orbit and unaesthetic appearance secondary to gunshot wound. Patient was not ready for any more surgical procedures or additional accessories and available retentive undercuts were minimal. Hence, conventional silicone prosthesis was made using stock eye shell and room temperature vulcanized silicone retained with skin adhesives. The approach was simple to a complex problem and gave reliable result in very limited time. Conclusion: With extensive orbital defect, rehabilitation is difficult and complex as retention is compromised and it is difficult to match the shade of the prosthesis.This case represents a simple and predictable approach to a case of exenterated right orbit with conventional roomtemperature vulcanized silicone and silicone skin adhesives.

Prosthetic Rehabilitation of an Orbital Defect Using Computer Aided Designing and Rapid Prototyping

Prosthesis development usingcontemporary technologies like computer aided designing andrapid prototyping is simple, cost effective and also improvesproductivity ensuring enhancement of the technical quality ofcare.Case report: The present case report describes rehabilitationof a patient of left anophthalmic residual defect with a custommade silicone orbital prosthesis retained with spectacle,developed with the help of computer aided designing andrapid prototyping technology.Conclusion: Consistent good quality prosthesis may beobtained using advanced digital technologies that includeoptical scanning, computer-aided designing and rapidprototyping which are more objective in nature.

Características clínicas y patológicas de los tumores orbitarios / Clinical and pathological characteristics of orbital tumors

Objetivo: describir las características clínico-patológicas de los tumores orbitarios. Métodos: se realizó un estudio descriptivo y retrospectivo de serie de casos en el Instituto de Oncología y Radiobiología desde enero del año 2011 a diciembre de 2017. La muestra se conformó con 241 pacientes sometidos a cirugía de la órbita y fue caracterizada según la edad, el sexo, el origen y la naturaleza de la lesión, el diagnóstico histopatológico y los abordajes quirúrgicos utilizados. Resultados: el 52,7 por ciento de la muestra estudiada fue del sexo masculino; el 36,5 por ciento se encontró en el grupo de 60 a 79 años. El 62,7 por ciento de los casos correspondió a tumores malignos, el 51,9 por ciento a lesiones primarias de la órbita y el 26,6 por ciento a linfoma No Hodgkin. Las lesiones secundarias originadas en los párpados representaron el 58,7 por ciento y el carcinoma epidermoide el 56,5 por ciento. Hubo 11 casos correspondientes a metástasis; las de mama representaron el 72,7 por ciento. El abordaje anterior transpalpebral fue utilizado en el 54,8 por ciento de los casos. Conclusiones: los tumores orbitarios se presentan con mayor frecuencia a partir de los 40 años de edad y con predominio del sexo masculino. Las lesiones malignas son más frecuentes, así como las primarias de la órbita, donde el linfoma No Hodgkin representa el mayor número de casos. Los párpados son la principal estructura de origen de las lesiones secundarias, y el carcinoma epidermoide es la variedad histopatológica predominante. Las metástasis de mama son las que más afectan el espacio orbitario. La vía de abordaje fundamental es la anterior transpalpebral (transeptal), seguido de la exenteración orbitaria(AU)

Objective: describe the clinicopathological characteristics of orbital tumors. Methods: a retrospective descriptive case-series study was conducted at the National Institute of Oncology and Radiobiology from January 2011 to December 2017. A sample of 241 patients undergoing orbital surgery was characterized according to age, sex, origin and type of lesion, histopathological diagnosis and surgical procedures used. Results: 52.7 percent of the study sample was male and 36.5 percent was in the 60-79 age group. 62.7 percent of the cases were malignant tumors, 51.9 percent were primary orbital lesions, and 26.6 percent were non-Hodgkin lymphomas. Secondary lesions originating in the eyelids represented 58.7 percent, and epidermoid carcinomas 56.5 percent. Eleven cases were metastases, 72.7 percent were of the breast type. The anterior transpalpebral approach was used in 54.8 percent of the cases. Conclusions: orbital tumors are more common as of age 40 with a predominance of the male sex. Malignant lesions are more frequent, as well as primary orbital lesions, of which the largest number of cases are non-Hodgkin lymphomas. The eyelids are the main structure of origin of secondary lesions, and epidermoid carcinoma is the prevailing histopathological variety. Breast metastases are the type most commonly affecting the orbital area. The main approach is anterior transpalpebral (transeptal), followed by orbital exenteration(AU)

To Evaluate The Results Of Complete Exenteration Of Mastoid Air Cell Tracts Underlying Cholesteatoma With Canal Wall Down Mastoidectomy

Chronic Suppurative Otitis Media(CSOM) is long standing infection of mucoperiosteal lining of middle ear cleft. CSOM is classified into Tubotympanic or Safe and Atticoantral or Unsafe type. Atticoantral type involves the pars flaccida and is characterized by formation of a retraction pocket in which keratin accumulates to produce cholesteatoma. Mainstay of the management of atticoantral disease is surgery of mastoid and middle ear. Majority of otolaryngologists find the Canal wall down , open cavity operation with wide access to be the safest and simplest means of managing middle ear cholesteatoma. In present study , results of complete exenteration of mastoid air cell tracts underlying cholesteatoma with canal wall down mastoidectomy are studied.

The influence of surgeon volume on outcomes after pelvic exenteration for a gynecologic cancer / 부인종양

OBJECTIVE: To determine the effect of surgeon experience on intraoperative, postoperative and long-term outcomes among patients undergoing pelvic exenteration for gynecologic cancer. METHODS: This was a retrospective analysis of all women who underwent exenteration for a gynecologic malignancy at MD Anderson Cancer Center, between January 1993 and June 2013. A logistic regression was used to model the relationship between surgeon experience (measured as the number of exenteration cases performed by the surgeon prior to a given exenteration) and operative outcomes and postoperative complications. Cox proportional hazards regression was used to model survival outcomes. RESULTS: A total of 167 exenterations were performed by 19 surgeons for cervix (78, 46.7%), vaginal (43, 25.8%), uterine (24, 14.4%), vulvar (14, 8.4%) and other cancer (8, 4.7%). The most common procedure was total pelvic exenteration (69.4%), incontinent urinary diversion (63.5%) and vertical rectus abdominis musculocutaneous reconstruction (42.5%). Surgical experience was associated with decreased estimated blood loss (p < 0.001), intraoperative transfusion (p = 0.009) and a shorter length of stay (p = 0.03). No difference was noted in the postoperative complication rate (p = 0.12–0.95). More surgeon experience was not associated with overall or disease specific survival: OS (hazard ratio [HR] = 1.02; 95% confidence interval [CI] = 0.97–1.06; p = 0.46) and DSS (HR = 1.01; 95% CI = 0.97–1.04; p = 0.66), respectively. CONCLUSION: Patients undergoing exenteration by more experienced surgeons had improvement in intraoperative factors such as estimated blood loss, transfusion rates and length of stay. No difference was seen in postoperative complication rates, overall or disease specific survival.

Orbital exenteration for a third eyelid gland carcinoma in a dog / 대한수의학회지

A 13-year-old neutered male Poodle dog was presented with a third eyelid mass in the left eye. The dog had undergone local resection of the mass about a year prior in a private practice. On cytological examination, the mass was diagnosed as adenocarcinoma. Although lung and lymph node metastases were suspected, based upon the computed tomographic results, exenteration was performed to relieve chronic pain and to improve the dog's quality of life. Exenteration carried a good prognosis with no tumor recurrence until 1 year and 10 months after surgery, when local recurrence occurred near the left zygomatic arch.

Pelvic exenteration for primary and recurrent malignancies in urology department / 中华泌尿外科杂志

Objective The objectives of present study is to investigate the safety and efficacy of pelvic exenteration (PE) for the treatment of pelvic malignancies in urology department.Methods From April 2010 to December 2014,20 patients with primary or recurrent pelvic malignancy accepted anterior pelvic exenteration (APE) or total pelvic exenteration (TPE) surgery,including 7 males and 13 females,ranged from 35 to 87 years old with an average of 65 years old.Ten case accepted APE and 10 for TPE.The ilium conduit was done in 5 cases for APE and 6 cases for TPE as urinary diversion,cutaneous ureterostomy was done in 5 cases for APE and 4 cases for TPE as urinary diversion.There were 6 cases primary tumor in APE group and 3 primary tumors in TPE.All of the patients had 13 cases of the urinary tract tumor group,and none of the urinary tract tumor group in 7 cases.There were 4 cases received preoperative chemotherapy in the urinary tract tumor group.No case received preoperative radiotherapy.3 cases received preoperative chemotherapy in none of the urinary tract tumor group,3 cased received preoperative radiotherapy.After induction of general anesthesia using a laryngeal mask for airway management.All patients took the abdominal incision,then dissected lymph nodes on both sides of the iliac vessels,freed bilateral ureters to the end of the swollen bladder,separated the peritoneal space.The bilateral vas deferens was cutted and ligated,then isolated and ligated the seminal vesicles between the posterior wall of the bladder and the anterior wall of the rectum.Lateral ligaments of bladder was cuted,then cuted ligament of prostate and puboprostatic ligament,sutured and cut deep vein of penis.Urethra of apex prostate was freed and cuted.Female patients needed to free the uterus and the posterior wall,cut the cardinal ligament and round ligament of uterus,isolate the posterior wall of the uterus to the posterior vaginal wall.Rectal resection adopted Miles operation.And sigmoid colostomy was performed on the left side of the abdominal wall.The perioperative characters,pathological results and patients' survival data were collected and analyzed.Results The average operation time for APE was 3.8 hours and 5.2 hours for TPE (P =0.173).Median length of hospital stay was 17.9 (7-47) days.The median blood loss was 300ml (80-2 500 ml) for APE and 400ml (50-6 000 ml) for TPE (P =0.909).The median follow-up time was 12.5 months (1-41months).The estimated 2-year survival rate for APE was 55.6％ and 45.0％ for TPE (P =0.642).Urinary system tumors group and non urinary system tumors group were analyzed and compared,The median survival time was 28 months and 13 months (P =0.538) in the two groups.The incidence of gastrointestinal complications of urinary system tumors and non-urinary system tumors was 7.7％ and 28.6％,incision complications was 7.7％ and 28.6％.Complications of urinary diversion only occurred in the non urologic tumor group,the incidence was 14.3％.The incidence of transfusion in two groups was 46.2％ and 28.6％.Conclusions Pelvic exenteration (APE and TPE) could be a safe and reliable choice for local advanced primary and recurrent pelvic malignancy.Even for the recurrent malignancies,the survival results of the patients were satisfactory.
