Origen y desarrollo de la cirugía del desprendimiento de retina con implantes esclerales y su introducción en Cuba Origin and development of retina detachment surgery with scleral implants and its introduction in Cuba

Se realizó una revisión bibliográfica con el objetivo de conocer los orígenes del tratamiento quirúrgico del desprendimiento regmatógeno de retina, el desarrollo de la técnica quirúrgica mediante implantes esclerales y su introducción en Cuba, así como su utilización hasta nuestros días. Son abordados tópicos como la creación del primer servicio de retina en el Hospital "Ramón Pando Ferrer", la visita de Charles Schepens a La Habana y la labor de importantes profesores vinculados al desarrollo de la especialidad en Cuba. Se consultó una bibliografía que abarca un período de varios años hasta el presente para conocer los resultados de la utilización de esta técnica quirúrgica en la actualidad y demostrar, de esa forma, su vigencia.<br>A bibliographic review was conducted to know the origins of the surgical treatment of the retina regmatogen detachment, the development of the surgical technique using scleral transplantations, as well as its introduction in Cuba and its use until nowadays. Subjects like the creation of our first Retina Service, the visit of Charles Schepens to La Habana and the work of important professors linked with development of the specialty in Cuba were approached. The bibliography covering a period of some years until now was looked up to know the results of the use of such surgical technique in present time and to demonstrate its validity

Edema quístico macular diagnosticado por tomografía de coherencia óptica en pacientes operados de catarata Cystoid macular edema diagnosed with optical coherente tomography in patients operated on from cataract

OBJETIVOS: Describir la frecuencia de edema quístico macular diagnosticado por tomografía de coherencia óptica en pacientes operados de catarata senil en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer", de diciembre 2006 a febrero 2007. MÉTODOS: Se realizó un estudio descriptivo, prospectivo en 108 ojos de 94 pacientes operados, a los que se les realizó un examen con el Stratus OCT 3000 de Zeiss Meditec AG. RESULTADOS: El 20,3 % de los pacientes presentó edema quístico macular. El 59,1 % de pacientes con edema quístico macular no manifestaron sintomatología alguna. Existió mayor probabilidad de desarrollar edema quístico macular cuando ocurrieron complicaciones durante la cirugía. Se observó por biomicroscopia del polo posterior, quistes intrarretiniales perifoveolares en el 81,8 % de los operados, y una relación inversamente proporcional entre el grosor macular y la agudeza visual alcanzada. CONCLUSIONES: Un número apreciable de pacientes con edema quístico macular fueron diagnosticados por tomografía de coherencia óptica. Se presentó de manera asintomática en la mayoría de los pacientes. Existe mayor probabilidad de desarrollar edema quístico macular cuando ocurren complicaciones durante la cirugía, en especial la ruptura de la cápsula posterior con vitreorragia. Los cambios morfológicos que se presentan en estos pacientes determinan que exista una relación inversamente proporcional entre el grosor macular y la agudeza visual alcanzada.<br>OBJECTIVES: To describe the frequency of cystoid macular edema diagnosed with optical coherence tomography in patients operated on from senile cataract at "Ramón Pando Ferrer" Cuban Institute of Ophthalmology in the period from December 2006 to February 2007. METHODS: A prospective and descriptive study of 106 eyes from 94 surgical patients was conducted; they were examined with Zeiss Meditec AG Stratus OCT 3000. RESULTS: Of the total number of patients, 20,3 % presented with cystoid macular edema. No symptoms were felt by 59.1 % of patients with this edema. It was more likely to develop cystoid macular edema when there were complications at surgery. Posterior pole biomicroscopy allowed observing perifoveal intraretinal cysts in 81, 8 % of the operated patients and an inversely proportional relation between macular thickness and final visual acuity. CONCLUSIONS: A sizeable number of patients with cystoid macular edema were diagnosed with optical coherence tomography. This disorder occurred asymptomatically in most of patients. It was more likely to develop cystoid macular edema when complications occurred during the surgery, particularly the rupture of posterior capsule with vitreous hemorrhage. The morphological changes in patients with cystoid macular edema determine inversely proportional relations between macular thickness and final visual acuity

Microperimetría y tomografía de coherencia óptica en operados por cirugía convencional del desprendimiento de retina Microperimetry and optical coherente tomography in patients operated on by the convencional retinal detachment surgery

INTRODUCCIÓN: Se realizó un estudio descriptivo para determinar la agudeza visual, la microperimetría y la tomografía de coherencia óptica en operados por cirugía convencional de desprendimiento de retina regmatógeno, en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer" desde octubre de 2006 a marzo de 2007. MÉTODOS: Se estudiaron 26 pacientes que acudieron con oftalmoscopia y biomicroscopia normal y una evolución entre tres y seis meses. Se obtuvo mejor agudeza visual corregida, fijación, sensibilidad media, morfología y grosores maculares. RESULTADOS: La agudeza visual media fue de 0,41 y la fijación fue estable en la mayoría de los pacientes, la sensibilidad retiniana promedio fue de 11 decibeles. El hallazgo más frecuente fue el desprendimiento seroso. El grosor macular promedio fue de 246,3 micras. No se encontró relación estadística entre el tiempo de evolución preoperatorio y las características maculares del desprendimiento con respecto a estas pruebas. CONCLUSIONES: El estado funcional y anatómico de la retina no estuvo totalmente recobrado y pudiera ser monitorizado gracias a la microperimetría y la tomografía de coherencia óptica.INTRODUCTION: A descriptive study was made to determine the visual acuity, microperimetry and optical coherence tomography in patients operated on by the conventional rhegmatogenous retinal detachment at "Ramon Pando Ferrer" Cuban Ophthalmologic Institute from October 2006 to March 2007. METHODS: Twenty six patients, who had gone to the hospital with normal values in ophthalmoscopy and biomicroscopy and three-six months of disease development. Better corrected visual acuity, fixation, average sensitivity, morphology and macular thickness were obtained after surgery. RESULTS: Average visual acuity was 0,41 and fixation was stable in most of patients; average retinal sensitivity was 11 decibels. The most frequent finding was serum detachment. Average macular thickness was 246,3 micras. There was no statistical relation between preoperative time of disease development and the macular characteristics of detachment in these tests. CONCLUSIONS: The functional and anatomic state of the retina was not completely recovered and may be monitored based on microperimtery and optical coherence tomography

Patients with Crohn's disease have longer post-operative in-hospital stay than patients with colon cancer but no difference in complications' rate

BACKGROUNDRight hemicolectomy or ileocecal resection are used to treat benign conditions like Crohn's disease (CD) and malignant ones like colon cancer (CC).AIMTo investigate differences in pre- and peri-operative factors and their impact on post-operative outcome in patients with CC and CD.METHODSThis is a sub-group analysis of the European Society of Coloproctology's prospective, multi-centre snapshot audit. Adult patients with CC and CD undergoing right hemicolectomy or ileocecal resection were included. Primary outcome measure was 30-d post-operative complications. Secondary outcome measures were post-operative length of stay (LOS) at and readmission.RESULTSThree hundred and seventy-five patients with CD and 2,515 patients with CC were included. Patients with CD were younger (median = 37 years for CD and 71 years for CC (P &lt; 0.01), had lower American Society of Anesthesiology score (ASA) grade (P &lt; 0.01) and less comorbidity (P &lt; 0.01), but were more likely to be current smokers (P &lt; 0.01). Patients with CD were more frequently operated on by colorectal surgeons (P &lt; 0.01) and frequently underwent ileocecal resection (P &lt; 0.01) with higher rate of de-functioning/primary stoma construction (P &lt; 0.01). Thirty-day post-operative mortality occurred exclusively in the CC group (66/2515, 2.3%). In multivariate analyses, the risk of post-operative complications was similar in the two groups (OR 0.80, 95%CI: 0.54-1.17; P = 0.25). Patients with CD had a significantly longer LOS (Geometric mean 0.87, 95%CI: 0.79-0.95; P &lt; 0.01). There was no difference in re-admission rates. The audit did not collect data on post-operative enhanced recovery protocols that are implemented in the different participating centers.CONCLUSIONPatients with CD were younger, with lower ASA grade, less comorbidity, operated on by experienced surgeons and underwent less radical resection but had a longer LOS than patients with CC although complication's rate was not different between the two groups

The impact of stapling technique and surgeon specialism on anastomotic failure after right?sided colorectal resection: an international multicentre, prospective audit

Aim There is little evidence to support choice of technique and configuration for stapled anastomoses after right hemicolectomy and ileocaecal resection. This study aimed to determine the relationship between stapling technique and anastomotic failure. Method Any unit performing gastrointestinal surgery was invited to contribute data on consecutive adult patients undergoing right hemicolectomy or ileocolic resection to this prospective, observational, international, multicentre study. Patients undergoing stapled, side?to?side ileocolic anastomoses were identified and multilevel, multivariable logistic regression analyses were performed to explore factors associated with anastomotic leak. Results One thousand three hundred and forty?seven patients were included from 200 centres in 32 countries. The overall anastomotic leak rate was 8.3%. Upon multivariate analysis there was no difference in leak rate with use of a cutting stapler for apical closure compared with a noncutting stapler (8.4% vs 8.0%, OR 0.91, 95% CI 0.54–1.53, P = 0.72). Oversewing of the apical staple line, whether in the cutting group (7.9% vs 9.7%, OR 0.87, 95% CI 0.52–1.46, P = 0.60) or noncutting group (8.9% vs 5.7%, OR 1.40, 95% CI 0.46–4.23, P = 0.55) also conferred no benefit in terms of reducing leak rates. Surgeons reporting to be general surgeons had a significantly higher leak rate than those reporting to be colorectal surgeons (12.1% vs 7.3%, OR 1.65, 95% CI 1.04–2.64, P = 0.04). Conclusion This study did not identify any difference in anastomotic leak rates according to the type of stapling device used to close the apical aspect. In addition, oversewing of the anastomotic staple lines appears to confer no benefit in terms of reducing leak rates. Although general surgeons operated on patients with more high?risk characteristics than colorectal surgeons, a higher leak rate for general surgeons which remained after risk adjustment needs further exploration

The relationship between method of anastomosis and anastomotic failure after right hemicolectomy and ileo-caecal resection: an international snapshot audit.

BACKGROUND: Anastomosis technique following right sided colonic resection is widely variable and may affect patient outcomes. This study aimed to assess the association between leak and anastomosis technique (stapled versus handsewn) METHODS: This was a prospective, multicentre, international audit including patients undergoing elective or emergency right hemicolectomy or ileo-caecal resection operations over a two-month period in early 2015. The primary outcome measure was the presence of anastomotic leak within 30 days of surgery, using a pre-specified definition. Mixed effects logistic regression models were used to assess the association between leak and anastomosis method, adjusting for patient, disease and operative cofactors, with centre included as a random effect variable. RESULTS: This study included 3208 patients, of whom 78.4% (n=2515) underwent surgery for malignancy and 11.7% (n=375) for Crohn's disease. An anastomosis was performed in 94.8% (n=3041) of patients, which was handsewn in 38.9% (n=1183) and stapled in 61.1% (n=1858) cases. Patients undergoing handsewn anastomosis were more likely to be emergency admissions (20.5% handsewn versus 12.9% stapled) and to undergo open surgery (54.7% versus 36.6%). The overall anastomotic leak rate was 8.1% (245/3041), which was similar following handsewn (7.4%) and stapled (8.5%) techniques (p=0.3). After adjustment for cofactors, the odds of a leak were higher for stapled anastomosis (adjusted odds ratio 1.43, 95% confidence interval 1.04-1.95, p=0.03). DISCUSSION: Despite being used in lower risk patients, stapled anastomosis was associated with an increased anastomotic leak rate in this observational study. Further research is needed to define patient groups in whom a stapled anastomosis is safe. This article is protected by copyright. All rights reserve
