Caracterización de las técnicas quirúrgicas para el tratamiento de la enfermedad hemorroidal

Introducción: En el tramo distal del conducto anal es normal la presencia de unas estructuras a modo de cojines, constituidas por tejido vascular, denominadas plexos hemorroidales. Objetivo: Comparar las técnicas quirúrgicas abiertas y cerrada en la enfermedad hemorroidal en la provincia Camagüey, en el periodo comprendido desde enero de 2021 a enero de 2023. Métodos: Se realizó un estudio observacional, analítico de corte transversal. El universo lo conformaron 135 pacientes que acudieron a consulta con el diagnóstico de enfermedad hemorroidal. Se le realizó un muestreo aleatorio simple, donde se tomaron 15 pacientes de cada uno de los grupos para conformar una muestra total de 45, cada grupo fue tratado con una técnica quirúrgica diferente. Resultados: En relación al sexo predominó el femenino, el tiempo quirúrgico fue dado a los 30 minutos en las técnicas abiertas. El dolor postoperatorio como complicación inmediata fue significativo con la utilización de la técnica abierta Whitehead clásico, no existieron complicaciones mediatas en el estudio; mientras que en las tardías la estenosis anal fue la que más se manifestó. Conclusiones: Existió predomino del sexo femenino, el tiempo de quirúrgico de mayor frecuencia fue de 30 minutos en los pacientes operados con la técnica abiertas, en la mayor parte de los pacientes se constató dolor excesivo como complicación inmediata con las técnicas de Milligan-Morgan y Whitehead clásico abiertas no así con la cerrada de Ferguson. La estenosis anal fue la complicación quirúrgica tardía más frecuente asociada a la técnica de Whitehead clásico.

Introduction: In the distal section of the anal canal, the presence of "cushion"-like structures, mainly made up of vascular tissue, called hemorrhoid plexuses. Objective: To compare the open and closed surgical techniques in hemorrhoid disease in Camagüey province, in the period from January 2021 to January 2023. Methods: An observational, analytical, cross-sectional study was carried out. The universe was made up of 135 patients who attended the consultation with the diagnosis of hemorrhoid disease. A simple random sampling was carried out, where 15 patients from each of the groups were taken to form a total sample of 45 patients, each group was treated with a surgical technique. Results: In relation to sex, the female sex predominated, the surgical time was given at 30 minutes in the open techniques. Postoperative pain as an immediate complication was significant with the use of the classic Whitehead open technique; there were no mediate complications in this study; while in the late ones, anal stenosis was the one that manifested itself the most. Conclusions: There was a predominance of the female sex, the most frequent surgical time was 30 minutes in patients operated with the open technique, in most patients excessive pain was found as an immediate complication with the Milligan-Morgan and classic Whitehead open techniques, but not so with the closed technique of Ferguson. Anal stenosis was the most frequent late surgical complication associated with the classic Whitehead technique.

A new double graft technique in urethroplasty for complex urethral stenosis: preliminary findings

ABSTRACT The management of complex urethral stenosis may involve different surgical techniques. As retraction of the graft may account for surgical failure, this risk increases in patients with more extensive stenosis requiring a graft of greater diameter. Although double grafts have already been used to maximize success in these cases, we propose a modified technique for urethroplasty with longitudinal urethral incision. The hypothesis was that this technique would increase the lumen by using only a urethral incision on the dorsal surface. Two patients presenting with recurrent urethral stenosis underwent urethroplasty using a double graft of oral mucosa that preserves the integrity of the spongy tissue and allows ventral inlay graft fixation using a midline relaxing incision in the portion of the urethra with stenosis. In both cases, the urethrocystoscopy and uroflowmetry performed after surgery showed a pervious and complacent urethra. After four and six months of follow-up, the postoperative outcomes were satisfactory for both patients. Further studies involving larger numbers of patients and long-term follow-up are required to evaluate the effectiveness of this method.

Mohs micrographic surgery: a review of indications, technique, outcomes, and considerations

Abstract Mohs micrographic surgery is a specialized form of skin cancer surgery that has the highest cure rates for several cutaneous malignancies. Certain skin cancers can have small extensions or "roots" that may be missed if an excised tumor is serially cross-sectioned in a "bread-loaf" fashion, commonly performed on excision specimens. The method of Mohs micrographic surgery is unique in that the dermatologist (Mohs surgeon) acts as both surgeon and pathologist, from the preoperative considerations until the reconstruction. Since Dr. Mohs's initial work in the 1930s, the practice of Mohs micrographic surgery has become increasingly widespread among the dermatologic surgery community worldwide and is considered the treatment of choice for many common and uncommon cutaneous neoplasms. Mohs micrographic surgery spares the maximal amount of normal tissue and is a safe procedure with very few complications, most of them managed by Mohs surgeons in their offices. Mohs micrographic surgery is the standard of care for high risks basal cell carcinomas and cutaneous squamous cell carcinoma and is commonly and increasingly used for melanoma and other rare tumors with superior cure rates. This review better familiarizes the dermatologists with the technique, explains the difference between Mohs micrographic surgery and wide local excision, and discusses its main indications.

Efficacy of probing for congenital nasolacrimal duct obstruction in a private tertiary hospital: 10-year experience / Eficácia de sondagem para obstrução congênita de ducto nasolacrimal em hospital terciário privado: 10 anos de experiência

ABSTRACT Objetive: To evaluate the success rate of initial and repeated probing as treatment approach for congenital nasolacrimal duct obstruction (CNLDO) in children between 2 and 46 months. Methods: A restrospective review of 73 children diagnosed with CNLDO who underwent probing of the NLD from March 2010 to 2020 was conducted. Data were colected from Hospital Oftalmológico de Anápolis in Anápolis, Goiás. Results: The procedure was performed in 90 eyes. The study sample was constituted of 36 males and 37 females. Bilateral involvement occurred in 18 (24.6%) children whereas 55 (75.3%) of them were unilaterally affected. The age ranges of the patients were divided into 4 groups: A - up to 6 months old (5.5% of the eyes), B - 7 to 12 months (27.5%), group C - 13 to 24 months (39.5%) and group D - older than 24 months (26.4%). The mean age of the sample was 18.6 months. Initial probing obtained an overall success rate of 88.8% and group B showed the best percentage (96%) from all age ranges. The second intervention had a lower outcome, successfuly in 55.5% of the cases. Conclusion: All age ranges showed high success rates for initial probing, although there was a decrease in subsequent procedures outcomes. Our results demonstrate that the success rate for primary probing is not affected by age.

RESUMO Objetivo: avaliar a taxa de sucesso de sondagem inicial e de repetição como abordagem de tratamento para obstrução congênita do ducto nasolacrimal em crianças entre 2 e 46 meses. Métodos: conduziu-se uma revisão retrospectiva de 73 crianças diagnosticadas com obstrução congênita do ducto nasolacrimal que se submeteram à sondagem do ducto nasolacrimal de março de 2010 a 2020. Os dados foram coletados no Hospital Oftalmológico de Anápolis em Anápolis, Goiás. Resultados: o procedimento foi realizado em 90 olhos. A amostra do estudo constitui-se em 36 pacientes do sexo masculino e 37 do sexo feminino. O acometimento foi bilateral em 18 crianças, enquanto 55 (75,3%) delas foram afetadas de forma unilateral. Os pacientes foram divididos em 4 grupos, de acordo com a faixa etária: A- até 6 meses de vida (5,5% dos olhos); B- 7 a 12 meses (27,5%); grupo C- 13 a 24 meses (39,5%) e grupo D- mais que 24 meses (26,4). A média de idade de amostra foi de 18,6 meses. A sondagem inicial teve uma taxa de sucesso global de 88,8%, e o grupo B mostrou a melhor porcentagem (96%) de todas as faixas etárias. A segunda intervenção teve uma taxa de sucesso menor, de 55,5% dos casos. Conclusão: todas as faixas etárias mostraram altas taxas de sucesso na sondagem, embora tenha havido um decréscimo nos resultados dos procedimentos subsequentes. Nossos resultados demonstram que a taxa de sucesso na sondagem primária não é afetada pela idade

A narrative review of invasive diagnostics and treatment of early lung cancer.

The diagnosis and treatment of early-stage lung cancer remains a clinical challenge. The broadening implementation of lung cancer screening has resulted in positive findings in numerous patients that are mostly non-malignant. Many other patients have indeterminate nodules that are difficult to assess through simple observation. The critical interpretation of such screening results remains a challenge for radiologists and multidisciplinary teams involved in screening for lung cancer. The evaluation and diagnosis of each participant suspected for malignancy should be based on the basic clinical principles such as a carefully collected medical history, physical examination, and detailed analysis of all imaging tests performed. Indeed, the decision to go ahead with more invasive diagnostics requires consideration of the both the risks and benefits, with reflection upon the complete clinical and radiological picture. Although transthoracic needle aspiration biopsy remains the first-choice method of diagnosis, several newer technologies have slowly begun to emerge as potential replacements. The guiding strategy for method selection is to choose the least harmful approach that offers the most relevant potential insights. Transthoracic biopsy is an effective method that allows the collection of cytological and tissue material from small, peripheral tumors, but it carries a moderate risk of complications. Bronchofiberoscopy, especially in combination with electromagnetic navigation, fluoroscopy or radial EBUS, also allows effective diagnosis of the peripheral pulmonary nodules. One of the most important diagnostic methods is the EBUS examination, which allows determining of staging in addition to diagnosis. Anatomical lung lobe resection and lymphadenectomy or sampling of the hilar and mediastinal lymph nodes is currently the treatment of choice for patients with stage I and II non-small cell lung cancer (NSCLC), but sublobar resections are recommended when a patient has limited pulmonary function or other significant comorbidities. Notably, several studies have highlighted the potential utility of more limited resections in small malignant lesions less than 2cm in diameter, with pure AIS histology, when more than 50% of the diameter of pulmonary nodule has ground-glass opacity (GGO) attenuation on CT, or long volume doubling time (VDT). Videothoracoscopy is the preferred surgical approach for resection of early-stage lung cancer. Patients who are not candidates for surgery or do not agree to surgery can be offered radical radiotherapy. Stereotactic body radiation therapy (SBRT) is a type of radical radiotherapy with proven effectiveness, a high rate of local control and an acceptable risk of the development of later complications. Future trials are expected to define the role of SBRT in the treatment of early lung cancer in healthy subjects.

Functional results of hautmann neobladder with chimney modification and wallace ureteroileal anastomosis: initial experience with 22 patients

ABSTRACT Objective: To assess the functional outcomes and complications of modified Hautmann neobladder with Wallace ureteroileal anastomosis on a 6-8 cm long isoperistaltic chimney, following radical cystectomy. Materials and Methods: Between January 2015 and October 2019, 22 patients (18 men and 4 women) underwent radical cystectomy and Hautmann neobladder reconstruction with chimney modification and Wallace I ureteroileal anastomosis. The mean age of patients was 61 years (45-74 years). All procedures were performed by the same surgeon and the mean follow-up was 29.4 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), with particular attention addressed to the ureteroileal anastomotic stricture and anastomotic leakage rate. Patient evaluation also included symptom analysis for daytime continence and voiding frequency. Results: Ureteroileal anastomotic stricture was not detected as a cause of hydronephrosis. Hovewer, the anastomotic leakage occurred in one patient during the early postoperative period. Early complications occurred in 9 patients and the most common was bilateral hydronephrosis, detected in 5 examinees. Late complications occurred in 4 patients. Complete daytime and nighttime continence achieved in 18 and 16 patients respectively, with two patients (9%) still required intermittent catheterization three months after surgery. Conclusions: The functional results with modified Hautmann neobladder, incorporating short afferent limb in Wallace I uretero-enteric anastomosis, were efficient. This technique is an effective way to minimize potential uretero-enteric stricture, anastomotic leakage and incidence of vesicoureteral reflux.

Lund and Browder chart-modified versus original: a comparative study.

BACKGROUND: The Lund and Browder (LB) chart is currently the most accurate and widely used chart to calculate total body surface area affected by a burn injury. However, it is not easy to use charts to calculate burn percentages because of the difficulty in performing mathematical calculations with the percentages attributed to various body regions that are only partially burned. It is also cumbersome to have to perform mental calculations, especially in emergency situations. METHODS: We compared results from the LB chart with a modified Lund and Browder (MLB) chart using 10 assessors on five different burn wounds each drawn on both charts. RESULTS: Variability of results was significantly reduced using the MLB chart compared to the LB chart. CONCLUSIONS: Assessments performed using the MLB chart are less variable than those using the LB chart. Using this chart will help burn care providers rapidly, accurately, and reliably estimate burn extent.

CLINICAL AND HISTOPATHOLOGICAL AXILLARY ASSESSMENT / Avaliação clínica e histopatológica axilar após esvaziamento por câncer de mama

Introduction: The proper selection of patients for sentinel lymph node biopsy is essential and depends on the evaluation of the patient's prediction for lymph node involvement and an evaluation of the accuracy of the clinical examination. Objective: This study aimed to evaluate the axillary contents of 102 breast cancer patients with tumors between 3 and 5 centimeters who underwent axillary dissection between January 2010 and December 2013. Methods: The data were categorized according to positive or negative axillary clinical evaluation and positive or negative anatomopathological evaluation. Results: The value for positive predictive values for physical examination was 83.5% and the negative predictive value was 34.88%. In addition, axillary physical examination showed 63.6% sensitivity and 60% specificity. Most patients with axillary involvement in the anatomopathological evaluation correlated with tumor grade, size, location and angiolymphatic invasion. Conclusion: It is believed that a better evaluation of the prediction of lymph node involvement, considering some clinicopathological risk factors in patients with suspicious lymph nodes, should be performed to aid the preoperative study of the axilla and the axillary approach screening

Introdução: Atualmente, precisamos selecionar adequadamente as pacientes a serem submetidas à biópsia de linfonodo sentinela. Para isso, são imprescindíveis a avaliação da predição daquele paciente acerca do comprometimento linfonodal e a avaliação da acurácia do exame clínico. Objetivo: O presente estudo teve como objetivo avaliar o conteúdo axilar de pacientes portadoras de câncer de mama com tumores entre três e cinco centímetros submetidas ao esvaziamento axilar entre 2010 e 2013, por meio da análise de 102 prontuários. Métodos: Os dados foram categorizados segundo a avaliação clínica axilar positiva ou negativa e a avaliação anatomopatológica positiva ou negativa. Resultados: Observaram-se valor preditivo positivo do exame físico de 83,5% e preditivo negativo de 34,88%. O exame físico axilar mostrou sensibilidade de 63,6% e especificidade de 60%. A maioria das pacientes com comprometimento axilar no anatomopatológico mostrou correlação com o grau tumoral, tamanho, localização e invasão angiolinfática. Conclusão: Acredita-se que uma melhor avaliação quanto à predição do comprometimento linfonodal, levando em consideração alguns fatores clinicopatológicos de risco nas pacientes com linfonodos suspeitos, deve ser feita como auxílio no estudo pré-operatório da axila e triagem no tocante à abordagem axilar

Penile refracture: a preliminary report.

OBJECTIVE: To report our institutional experience with penile refracture, including demographic data, recurrence time, etiology and operative findings in the first and second episodes. MATERIALS AND METHODS: Between January 1982 and September 2017, 281 patients underwent surgical treatment for penile fracture (PF) at our institution. Demographic data, clinical presentation, besides operative findings and follow-up of patients with relapsed PF were retrospectively assessed by reviewing medical records. RESULTS: Of a total of 281 cases of PF operated at our institution, 3 (1.06%) patients experienced two episodes of trauma. Age ranged from 38 - 40 years (mean: 39.3). The recurrence time varied from 45 to 1560 days (mean: 705). Two patients presented the new fracture episode at the same site of the previous lesion, while in the other case the lesion was observed at another site. CONCLUSION: Recurrent FP is an extremely rare entity. The risk factors for its occurrence are still unknown. Although the lesion of the corpus cavernosum ipsilateral to the scar tissue of the prior FP is more common, contralateral rupture may be present. Nevertheless, prospective studies with larger samples should be conducted.

[Intraosseous lipoma: retrospective analysis of 19 patients].

OBJECTIVE: To investigate the diagnostic and therapeutic procedures of intraosseous lipoma. METHODS: From June 1986 to January 2016, 19 patients with intraosseous lipoma were treated including 12 males and 7 females, aged from 24 to 76 years, a predilection aged was from 40 to 50 years in 13 cases. Symptoms presented with pain or swelling in 15 patients, the lesions were found incidentally in 3 patients, another case was bone defect lipoma replacement after curettage of bone cyst for 4 years. On plain X-ray flims of all bones showed a well-circumscribed radiolucent area. Diagnosis was established with CT or MRI. Among them, 16 cases were treated by surgical operation, 3 cases were treated by concervative treatment. All patients' clinical data, histologic findings and X-ray, CT and MRI were analysed. RESULTS: Total 19 patients were followed up from 9 to 42 months with an average of 15 months. There was no local tumor recurrence in 16 patients after excising the tumors, the remaining 3 patients showed no enlargement of the lesion. CONCLUSIONS: Surgical intervention is considered as an unnecessary in the patients diagnosied intraosseous lipoma by MRI or CT. Patients with symptomatic should adopt surgical treatment with curettage and bone grafting.

Intraspinal lipomas without associated spinal dysraphism.

INTRODUCTION: The aim of this study was to report surgical strategies and clinical outcomes for thoraco-lumbar intradural lipomas. Intraspinal lipomas are rare congenital histologically benign neoplasms, which account for less than 1% of all spinal cord tumors. These tumors are most frequently found in the lumbosacral area as components of a dysraphic state, however, intramedullary lipomas are not associated with spina bifida or cutaneous malformations and have only been described as isolated cases among spinal lipomas, where the thoracolumbar region is rarely affected. CASE PRESENTATION: Three patients with thoracolumbar intradural lipomas were admitted to our clinic at different points of time. Partial resections and debulking of the tumors were achieved with the guidance of an operating microscope. We performed laminectomies or laminoplasties, for tumor resections. DISCUSSION: Postoperatively, the patients demonstrated significant clinical improvements. In this manuscript we presented our surgical experiences for intraspinal lipomas.

Incidence and pathological features of prostate cancer detected on transperineal template guided mapping biopsy after negative transrectal ultrasound guided biopsy.

PURPOSE: We determined the incidence of cancer detection by transperineal template guided mapping biopsy of the prostate in patients with at least 1 previously negative transrectal ultrasound guided biopsy. MATERIALS AND METHODS: From January 2005 to January 2012 at least 1 negative transrectal ultrasound guided biopsy was done in 485 patients in our clinical database before proceeding with transperineal template guided mapping biopsy. No study patient had a previous prostate cancer diagnosis. The incidence of patients with 1, 2, or 3 or greater previous transrectal ultrasound guided biopsies was 55.3%, 25.9% and 18.8%, respectively. Transperineal template guided mapping biopsy was done in 74.8% of patients for increasing or occasionally persistently increased prostate specific antigen, in 19.4% for atypical small acinar proliferation and in 5.8% for high grade prostatic intraepithelial neoplasia. RESULTS: For the entire study population a median of 59 cores was submitted at transperineal template guided mapping biopsy. Cancer was ultimately detected in 226 patients (46.6%) using the transperineal template guided method, including 196 (86.7%) with clinically significant disease according to the Epstein criteria. The most common cancer detection site on transperineal template guided mapping biopsy was the anterior apex. CONCLUSIONS: Transperineal template guided mapping biopsy detected clinically significant prostate cancer in a substantial proportion of patients with negative transrectal ultrasound guided biopsy. This technique should be strongly considered in the context of increasing prostate specific antigen with failed confirmation of the tissue diagnosis.

Laparoscopía y apendicectomía laparoscópica en niños: experiencia nacional / Laparoscopy and laparoscopic appendectomy in children: national experience

Introducción: la apendicitis aguda es la urgencia quirúrgica más frecuente en niños. Las dificultades diagnósticas determinan un porcentaje de apendicitis evolucionadas o de apendicectomías innecesarias. La morbilidad y la incidencia de estos eventos disminuye con la laparoscopía. Objetivo: presentar nuestra experiencia laparoscópica en niños, compararla con los trabajos internacionales y con la laparotomía en nuestro medio. Metodología: se realizó un trabajo retrospectivo de las laparoscopías diagnósticas (LD) y apendicectomías laparoscópicas (AL) en el período 2001-2009 . Se consideró: edad, sexo, tipo de apendicitis, tiempo quirúrgico, conversión, complicaciones, reintervención, estadía hospitalaria, antibioticoterapia, e histología. Se dividió la serie en un primer período de 50 apendicectomías en el que hubo criterios de exclusión, y un segundo de 75 en el que se desarrolló un aprendizaje tutorizado. Se compararon los dos períodos de la serie de AL entre sí, y la serie de AL con una serie local de apendicectomizados por vía abierta (AA). Las variables categóricas de interés se analizaron mediante test de Chi cuadrado, test de Fisher y test t de student, utilizando el programa Epi-info6. Resultados: se realizaron 164 procedimientos: 125 AL y 39 LD. Las primeras 50 AL se realizaron en 60 meses, y las 75 siguientes en 40. En el CHPR se realizaron 91 AL. La media de edad fue 10,2 (DE 1,9). Predominaron el sexo masculino (59%) y la apendicitis simple, que correspondió al 60,8% (76 casos). El índice de conversión en la serie fue de 4,8%, con disminución significativa (p=0,03) del primer período (10%) al segundo (1,3%). Hubo diferencia significativa (p de 0,002) en el tiempo quirúrgico entre el primer período (media 40’, DE 15,8) y el segundo (media 32’, DE 7,7). El índice de infección de la herida operatoria (IHO) en AL fue de 0,8% (un caso) y el de infección abdominal (IA) fue de 1,6% (dos casos)...

Introduction: acute appendicitis is the most common surgical emergency in children. The diagnostic difficulties determine a percentage of evolved appendicitis or unnecessary appendectomies. The morbidity and the incidence of these events diminishes with laparoscopy. Objective: to present our experience with laparoscopy in children, compared with international papers and laparotomy in our country.Method: we conducted a retrospective study of diagnostic laparoscopy (DL) and laparoscopic appendectomy (LA) in the period 2001-2009. Were considered: age, sex, type of appendicitis, surgical time, conversion, complications, reoperation, hospital stay, antibiotic therapy, and histology. We divided the series into a first period of 50 appendectomies in which there were exclusion criteria, and another 75 in which supervised learning was developed. We compared two periods of the AL series between themselves, and the number of AL with a local number with open appendectomy (AA). The categorical variables of interest were analyzed by Chi square, Fisher test and Student t test, using Epi-info 6.Results: 164 procedures were conducted: 125 AL and 39 LD. The first 50 were done in 60 months, and the following 75 in 40. The 91 were held CHPR AL. The mean age was 10.2 (SD 1.9). Males (59%) and simple appendicitis, which corresponded to 60.8% (76 cases), predominated. The conversion rate in the range was 4.8%, with significant reduction (p=0.03) from the first period (10%) to second (1.3%). There were significant reduction (p=0.002) in surgical time between the first period (average 40, DE 15.8) and second (mean 32', DE 7.7). The rate of surgical wound infection (SWI) in LA was 0.8% (one case) and abdominal infection (AI) was 1.6% (two cases). The AI and SWI in the series of AL was lower compared to the number of AA, with a significant reduction in SWI (p 0.001)...

Early diagnosis of primary ureteral neoplasms:report of 28 cases / 中国基层医药

Objective To evaluate the choice of early diagnosis method of primary ureteral neoplasms in or-der to improve the ratio of clinical diagnosis. Methods 28 cases with primary ureteral neoplasms were retrospectively analyzed. Ultrasonic examination, IVU, retrograde urogram, spiral CT, MRI, ureteroscopy and exfoliative cell examina-tion of urine were compared in this study. Results The most useful methods of detecting tumors preoperation were retrograde urogram, spiral CT, MRI, ureteroseopy. All the 28 patients underwent surgical treatment. Among them, nephroureterectomy and bladder cuff or partial resection were performed in 19 cases. Postoperative pathology showed transitional cell carcinoma in 27 cases,and adenoma in 1 case. 8 cases were T1-2 tumours. Of the 14 cases during 1990 ～1999 period, 1,5,3,2,2 and 1 cases had survival time of 1,2,3,4,5 and 6 years ,respectively. Of the 14 cases during 2000～2007,4 were lost to follow-up;2 survived for 3 years and 2 for 1 year;the other 6 who have survived near 5 years have been followed till now. Conclusions To improve the early diagnosis rate,B-ultrasonic examination, IVU,retrograde urogram,3D spiral CT and MRI examination were necessary in the early stage. The patients should be opeiated as early as possible after diagnosis.
