Experiencia quirúrgica en el Centro Especializado en Tratamiento de Enfermedades de la Piel (CETEP) del Centro Hospitalario Pereira Rossell, desde 1996 hasta 2019

Los tumores cutáneos presentan una alta prevalencia en dermatología en el mundo, siendo los benignos más frecuentes que los malignos; sin embargo, estos últimos son más estudiados debido a su morbimortalidad. El objetivo principal de este estudio fue conocer los principales diagnósticos y técnicas quirúrgicas correspondientes desarrolladas en el Centro de Tratamiento de Enfermedades de la Piel (CETEP) entre 1996 y 2019, evaluando aspectos clínicos y demográficos. Se realizó un estudio retrospectivo y observacional que incluyó todo paciente con lesión cutánea y posterior resolución quirúrgica de la misma. En la muestra analizada (N 6.659) hubo un predominio del sexo femenino (68%) y la media de edad fue 53 ± 21 años. Los pacientes residían mayoritariamente en Montevideo (58%). Los tumores benignos fueron los más frecuentes (41%), seguidos de los malignos (28%), dentro de éstos: carcinoma basocelular (CBC) 66%, carcinoma espinocelular (CEC) 21% y melanoma (MM) 5%. Las técnicas quirúrgicas realizadas fueron cirugías convencionales (57%), principalmente losange (93%), seguidas de procedimientos de cirugía dermatológica (42%), predominando biopsias (52%) y afeitado con electrocoagulación (23%). Se destaca que el CETEP resolvió un número mayor de pacientes de centros externos que del propio Centro Hospitalario Pereira Rossell (CHPR): 59% no CHPR vs 41% CHPR. En conclusión, este trabajo proporcionó información nacional sobre la epidemiología de distintos tumores cutáneos, así como las técnicas quirúrgicas más utilizadas en su resolución. Además, estableció la importancia de la cirugía dermatológica y la capacidad del CETEP en dar respuesta a pacientes propios tanto como referenciados desde otros centros del sistema público.

Cutaneous tumors have a high prevalence in dermatology worldwide, with benign tumors being more common than malignant ones. Nevertheless, the latter are more extensively studied due to their associated morbidity and mortality. The main objective of this study was to identify the primary diagnoses and corresponding surgical techniques developed at the Center for the Treatment of Skin Diseases (CETEP) between 1996 and 2019, while assessing clinical and demographic aspects. A retrospective, observational study was conducted, including all patients with cutaneous lesions and subsequent surgical resolution of the same.

Postauricular Transcanal Posterior Tympanectomy (PT2) Approach - A Modified Surgical Technique for Jugulotympanic Paragangliomas

Abstract Introduction The surgical management of jugulotympanic paragangliomas has remained challenging. They are the second most common type of tumor of the temporal bone after acoustic neuroma. It has been noticed by the authors that the jugulotympanic paragangliomas may have extensions to the epitympanum and aditus in addition to the mesotympanum and hypotympanum. The modified technique could be an alternative to the conventional facial recess technique for complete removal of the tumors. Objective To highlight the modified surgical technique for the surgical treatment of jugulotympanic paragangliomas. Methods This is a retrospective review of 34 cases of jugulotympanic paragangliomas treated in a tertiary center with respect to clinical presentation, diagnosis, and surgical treatment. Tinnitus and hearing loss were predominant symptoms. A modified technique of postauricular transcanal posterior tympanectomy with extended hypo-tympanic access was performed in 29 patients. Only two cases were operated with a classical transcanal approach. A canal wall down the mastoidectomy was required in three patients. Results The patients operated on with the modified technique had complete excision evident by absence of any lesion in computed tomography and the disappearance of tinnitus. However, two patients had recurrence of symptoms and presence of tumor in the follow-up period. These two patients underwent revision surgery. None of the patients required postoperative radiotherapy or gamma knife therapy. Conclusions Jugulotympanic paragangliomas can be effectively managed with the modified technique to ensure complete removal of the lesions. This technique has not been reported earlier in the literature.

Pancreatectomía izquierda laparoscópica: ¿la sistematización de la técnica es de utilidad? / Laparoscopic left pancreatectomy: is systematization of the technique useful?

RESUMEN Antecedentes: la pancreatectomía izquierda laparoscópica es un procedimiento de alta complejidad que debe ser sistematizado para reducir complicaciones y tiempos quirúrgicos. Objetivo: Describir los resultados con una técnica sitematizada de esplenopancreatectomía laparoscópica. Material y métodos: se seleccionaron pacientes candidatos a realizar esplenopancreatecomía distal en el período comprendido entre 2007 y 2022. Se excluyeron pacientes con enfermedad sistémica. La técnica quirúrgica laparoscópica consiste en ligar los vasos cortos como primer paso, luego disecar y cortar la arteria esplénica, dejando la sección de la vena como último gesto quirúrgico. Esto evita la congestión venosa del bazo. Se analizaron variables preoperatorias, intraoperatorias y posoperatorias. Resultados: sobre un total de 155 pacientes, 90 fueron intervenidos por vía laparoscópica y 65 por vía convencional. El tiempo quirúrgico promedio fue 168 minutos. Cuando se analizó el tiempo quirúrgico en los abordajes laparoscópicos, se observó una disminución del tiempo a partir del caso número 30. La mortalidad fue del 1,12%. La incidencia de fístula pancreática total fue 41%. La necesitad de transfusión intraoperatoria ocurrió en el 10,7% de los pacientes y la tasa de conversión fue del 13,3%. Conclusión: la sistematización de la técnica de la pancreatectomía laparoscópica permite la reducción de los tiempos quirúrgicos, adquirir mayor seguridad en la disección y realizar procedimientos cada vez más complejos.

ABSTRACT Background: Laparoscopic left pancreatectomy is a high complexity procedure that should be systematized to reduce complications and operative time. Objective: To describe the results achieved with a systematized technique for laparoscopic pancreatectomy and splenectomy. Materials and methods: We selected patients who were candidates for distal pancreatectomy and splenectomy between 2007 and 2022. Patients with systemic diseases were excluded. The laparoscopic technique consists of ligating the short vessels as a first step, then dissecting and cutting the splenic artery, leaving the section of the vein as the last surgical gesture to avoid venous congestion of the spleen. Perioperative, intraoperative and postoperative variables were analyzed. Results: A total of 155 patients were analyzed, 90 underwent laparoscopy and 65 underwent conventional surgery. Mean operative time was 168 minutes The operative time in the laparoscopic approach decreased from case 30 onwards. Mortality rate was 1.12%. The incidence of pancreatic fistula was 41%. Need for intraoperative transfusion occurred in 10.7% of the patients and the conversion rate was 13.3%. Conclusion: The systematization of the technique of pancreatic laparoscopy is essential to reduce surgical times, ensure safe dissections and performe more complex procedures.

Clinical and follow-up study of premature infants with neonatal respiratory distress syndrome managed by the less invasive surfactant administration / 中华实用儿科临床杂志

Objective:To explore the clinical therapeutic effect and follow-up prognosis of preterm infants with neonatal respiratory distress syndrome (NRDS) managed by less invasive surfactant administration (LISA) and traditional intubation-surfactant-extubation (INSURE) of pulmonary surfactant (PS).Methods:Data during hospitalization and follow-up period of 187 NRDS preterm infants (gestational age 24 weeks to 31 + 6 weeks, and birth weight <1 500 g) admitted to the Department of Neonatology, the Women and Children′s Hospital of Chongqing Medical University from March 2019 to February 2021 were retrospectively analyzed.NRDS preterm infants who were injected with PS by LISA were included in the LISA group (144 cases), and those who were injected with PS by INSURE were included in the INSURE group (43 cases). The propensity score matching method was used to correct the confounding factors between groups, and the covariate equilibrium samples between groups were obtained (39 cases in each group). Clinical treatment effect and prognosis of physical development, hearing and vision development, nervous system development, respiratory system diseases and other conditions of the two groups of children were compared using the t test, Chi- square test and other statistical analysis methods as appropriate. Results:(1)Compared with that of the INSURE group, the incidence of BPD [12 cases (33.3%) vs.23 cases (63.9%), χ2=6.727, P=0.009] and ROP [13 cases (36.1%) vs.26 cases (72.2%), χ2=9.455, P=0.002] in the LISA group were significantly lower.The incidence of mild BPD [8 cases (22.2%) vs.16 cases (44.4%), χ2=4.000, P=0.046] and stage Ⅰ-Ⅱ ROP [11 cases (30.6%) vs.22 cases (61.1%), χ2=6.769, P=0.009] in the LISA group was significantly lower than that of the INSURE group.There was no significant difference in the incidence of moderate and severe BPD and stageⅢ ROP and above between groups (all P>0.05). (2)There were no statistical differences in the repeated use of PS, mechanical ventilation rate within 72 h, pneumothorax/pulmonary hemorrhage, grade Ⅲ-Ⅳ periventricula-rintraventricular hemorrhage, stage Ⅱ-Ⅲ neonatal necrotizing enterocolitis, sepsis, abnormal amplitude integrated electroencephalogram, mortality in 36 weeks of corrected gestational age, total oxygen inhalation duration and hospitalization duration between the two groups (all P>0.05). (3)Follow-up within 1 year of corrected age after discharge.There were no significant differences in extrauterine body mass, body length and head circumference development, visual development, hearing development, Neonatal Behavioral Neurological Assessment score at corrected gestational age of 40 weeks, Bayley Scales of Infants Development score at corrected gestational age of 6 months and age of 1 year, pneumonia and re-hospitalization due to respiratory diseases between groups (all P>0.05). Conclusions:PS administration with LISA technology can reduce the incidence of mild BPD and stage Ⅰ-Ⅱ ROP in premature infants with NRDS who had the gestational age of 24-31 + 6 weeks and birth weight<1 500 g, without increasing the risk of other complications.The long-term prognosis of them treated with PS administration with LISA and INSURE is similar.

Comprehensive orthodontic treatment of impacted teeth / 口腔疾病防治

@#Impacted teeth are a kind of complex malocclusion, and their incidence differs among different races, sexes and dental positions. The causes of impacted teeth include systemic factors and local factors, such as endocrine disorders, malnutrition, and acute and chronic infectious diseases. Local factors can cause abnormal tooth development or eruption during the process from tooth development to tooth eruption, such as damaged permanent tooth embryos caused by local inflammation or trauma, insufficient eruption space caused by premature loss of deciduous teeth, and eruption disorders caused by local lesions for example hyperplasia or odontoma. The clinical manifestation of impacted teeth is the absence of a permanent tooth in a normal position. We can use cone beam CT (CBCT) to locate the impacted teeth. Comprehensive orthodontic treatment includes surgical-assisted eruption, extraction of retained deciduous teeth or supernumerary teeth, removal of lesions such as odontomas and cysts, and expansion of the orthodontic space. When the dysfunctional local soft and hard tissues are removed during a surgical operation, the tooth still cannot sprout smoothly, and it needs to be assisted by orthodontic traction-guided eruption or extracted and autotransplantation. A clear diagnosis, evaluation of the difficulty of treatment and appropriate treatment are the keys to improving the success rate of treatment. In this paper, the epidemiology, etiology, diagnosis and corresponding treatment methods of impacted teeth will be reviewed, and the orthodontic treatment of impacted teeth will be comprehensively described to provide a reference for clinicians about the treatment of impacted teeth.

The use of integrin binding domain loaded hydrogel (RGD) with minimally invasive surgical technique in treatment of periodontal intrabony defect: a randomized clinical and biochemical study

Abstract Periodontal regeneration faces multiple challenges, the most important being cellular insufficiency. In an attempt to improve defect cellularity, we aimed to demonstrate enhancing cellular attraction using arginine-glycine-aspartic acid (RGD) adhesion molecule legend blended hydrogel within the intrabony defects. Methodology Forty-five intrabony defects were selected from patients with stage III or IV - grade A or B periodontitis and divided randomly into three equal groups of 15 each: group1 (G1): received minimally invasive surgical technique (MIST) alone, group2 (G2): received MIST and placebo hydrogel injection, and group3 (G3): were treated with MIST and RGD hydrogel injection. Primary outcomes 6 months following therapy were; defect base fill (DBF) and defect width measurement (DW); secondary outcomes were clinical attachment level (CAL), pocket depth (PD), plaque index (PI), gingival index (GI), and biochemical analysis of bone morphogenetic protein (BMP-2) evaluated at 1,7,14 and 21 days following therapy. Results Significant improvements in DBF, CAL, and PD were observed in the three studied groups 6 months following therapy compared to baseline (p<0.05). A significant improvement in DBF was reported in G3 compared to G1 and 2 (p=0.005). Additionally, a significantly higher CAL gain was reported in G3 compared to that of G1 (p=0.02). Group 3 was associated with a significantly higher level of BMP-2 compared to G1 and G2 in all reported periods. Conclusion RGD peptide carried on a hydrogel delivery agent and contained with a minimally invasive flap could be a reliable option in improving the outcomes of periodontal therapy.

@#Objective    To summarize the treatment results of double aortic arch (DAA) by minimally invasive surgical technique. Methods    We retrospectively analyzed the clinical data of DAA patients who underwent minimally invasive surgeries in our center between October 2016 and August 2021. Results    There were 11 males and 4 females with a mean age of 3-61 (20.00±18.80) years. There were 8 patients of DAA and 7 patients of DAA complicated with distal left-sided aortic arch atresia and ligamentum connection. All patients received operations through minimal subaxillary incision, 13 patients were through left side and 2 patients were through right side. One patient with ventricular septal defect was performed operations concurrently under the cardiopulmonary bypass through right minimal subaxillary incision. All patients had symptom improvement without surgery related complications or death in postoperative period. The duration of operation was 30-192 (61.93±40.19) min and mechanical ventilation time was 2-9 (5.33±2.53) h. The length of ICU stay was 18-124 (51.00±38.07) h and hospital stay time was 8-21 (12.67±3.42) d. All patients had sympto-matic relief with good growth and exercise tolerance during the follow-up of 6 (3, 9) months. Conclusion    Minimally invasive surgical technique is a safe, effective and cosmetic approach with good results for DAA treatment.

Manual small-incision cataract surgery under topical anesthesia

Manual small-incision cataract surgery is one of the most common surgical procedures in ophthalmology. Most cataract surgeries are performed under local anaesthesia. Peribulbar or retrobulbar anaesthesia is commonly used to achieve analgesia and akinesia during surgery but it has various complications. Our aim was to study patient comfort and surgeon抯 perspective in terms of patient cooperation in MSICS under topical anaesthesia using only proparacaine 0.5% eye drops without any periocular block or intracameral drug. Also to popularise Topical MSICS similar to Topical Phacoemulsification. A prospective analytical study of 33 patients who underwent MSICS surgery from March 2022 to June 2022 using Topical proparacaine eye drops 0.5% was done and patient抯 comfort and surgeon抯 perspective in terms of patient cooperation was studied on a scale of 1-5. Out of 33 patients who underwent surgery, the average comfort score based on patient feedback was 3.45� 0.96 and average patient cooperation score based on surgeon assessment was 3.42 � 1.07 on a scale of 1-5. We concluded that MSICS using only topical proparacaine 0.5% eye drops, can provide sufficient patient comfort and can avoid complications related to peribulbar anaesthesia. Hence it can be used in large scale cataract surgeries and also provides economical utilisation of resources, lesser complications and early post operative recovery without compromising surgical outcome.

Simplified technique for lateral canthal tendon canthopexy

Purpose: Different techniques for lateral canthal suspension have been used in the management of various eyelid malpositions. We describe a simplified technique for lateral canthal suspension and review its outcome along with a review of existing variations. Methods: We conducted a retrospective chart review of 28 eyelids in 22 patients who underwent simplified lateral canthal suspension. Demographics, symptoms at presentation, and associated eyelid malposition were noted. We evaluated the palpebral fissure and margin?reflex distance 2 (MRD2) on the preoperative and final postoperative photographs by using MEEI FACE?gram software. We also reviewed existing literature on different surgical management options for comparison. Results: At three?month postoperative follow?up, presenting symptoms resolved in all cases. The average postoperative decease in palpebral fissure was 0.73 mm (P = 0.018) and the average decrease of the MRD2 was 1.02 mm (P = 0.0003). Recurrence occurred by three months in one eyelid (4%) with ectropion due to moderate eyelid laxity, and this case was managed with tarsal strip procedure. One patient (5%) who had bilateral surgery had asymmetric lower eyelid position and one patient (5%) had persistent edema of the operated eyelid for six months. Conclusion: This simplified canthal suspension is a simple and effective technique that tightens the lateral canthal tendon and improves the lower eyelid position. It can be used in various mild?to?moderate eyelid laxities and has favorable operative characteristics compared with many existing techniques

Resumen Introducción: La fístula rectovaginal es una patología quirúrgica compleja de tratar. El trauma perineal obstétrico y las enfermedades inflamatorias intestinales, especialmente la Enfermedad de Crohn son las causas más frecuentes. La reparación quirúrgica con un Colgajo de Martius en manos experimentadas ha mostrado buenos resultados con mínima morbilidad en pacientes seleccionados. Material y Método: Presentamos un caso clínico de una paciente que cursó con una fístula rectovaginal posparto tardía, la cual tuvo una recurrencia precoz, luego de intentar tratamiento quirúrgico consistente en un colgajo de avance, siendo necesaria la desfuncionalización del tránsito con una colostomía en asa. Posteriormente se realizó un Colgajo de Martius con resultado exitoso. Resultados: Evolución satisfactoria. Cursó con dehiscencia de la herida perineal la cual requirió solo curaciones ambulatorias. Luego de 8 meses posterior a la confección del Colgajo de Martius, se realizó el cierre de colostomía. A los 30 meses poscolgajo, la paciente se encuentra en buenas condiciones, sin evidencia de recidiva y tránsito intestinal normal. Conclusión: En este caso clínico, el colgajo de Martius fue una alternativa segura y efectiva en el tratamiento de una fístula rectovaginal recidivada.

Introduction: The rectovaginal fistula is a complex surgical pathology to treat. Obstetric perineal trauma and inflammatory bowel diseases, especially Crohn's disease, are the most frequent causes. Surgical repair with a Martius flap in experienced hands has shown good results with minimal morbidity in selected patients. Material and Methods: We present a clinical case of a patient who had a late postpartum rectovaginal fistula, which recurred early after attempting surgical treatment consisting of an advancement flap, requiring defunctionalization of the transit with a loop colostomy. Subsequently, a Martius flap was performed with a successful result. Results: Satisfactory evolution. The patient presented a dehiscence of the perineal wound which required only ambulatory dressings. At 8 months from the Martius flap was made, the colostomy was closed. At 30 months post-flap, the patient is in good condition, with no evidence of recurrence and normal intestinal transit. Conclusión: In this clinical case, the Martius flap was a safe and effective alternative in the treatment of a recurrent rectovaginal fistula.

@#Objective    To introduce a modified sutureless technique and its surgical results in the treatment of total anomalous pulmonary venous connection (TAPVC). Methods    Clinical data of 11 patients with TAPVC who underwent the modified sutureless technique treatment from 2014 to 2019 in our center were retrospectively analyzed, including 4 males and 7 females. The median surgical age was 1.4 (0.3, 27.0) months. The median weight was 4.3 (3.5, 8.5) kg. Six (54.5%) patients were of supracardiac subtype, and five (45.5%) patients were of infracardiac subtype. Five (45.5%) patients had preoperative severe pulmonary hypertension, and three (27.3%) patients had preoperative pulmonary vein obstruction. The surgical results were compared with those of 10 patients treated with conventional surgical technique. Results    The median follow-up was 12 (range, 1-65) months. During the follow-up, no death or postoperative pulmonary vein obstruction occurred in the modified sutureless technique group. The perioperative data and relief of re-obstruction were superior in the modified sutureless technique group, but the difference was not statistically significant (P>0.05). The postoperative survival of the the modified sutureless technique group was better than that of the traditional surgery group (P=0.049). Conclusion    The modified sutureless technique which includes partial suture and then incising, and eversion of pulmonary vein incision, is a safe and reliable method for the treatment of TAPVC with satisfactory short-term results.

Modified malleable prosthesis with a fixed mesh: case series for the Ghattas technique / 亚洲男科学杂志(英文版)

Penile prosthetic implantation represents a cornerstone for patients with organic erectile dysfunction (ED) that is refractory, unsatisfactory, or contra-indicated for other approved medical or mechanical options. In this study, we introduce the "Ghattas technique," wherein we constructed a polypropylene mesh sheath that surrounds and is fixed to a 13-mm malleable prosthesis cylinder, which can increase the cylinder diameter for cases that need a larger prosthesis. All patients underwent preoperative evaluation and completed the five-item International Index of Erectile Function questionnaire (IIEF-5). Postoperative outcomes were evaluated by IIEF-5 and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaires at final follow-up. The mean age of the 23 included patients was 57.9 (standard deviation [s.d.]: 11.4) years and the mean duration of ED was 8.5 (s.d.: 7.9) years. Erection improvement was determined by comparing mean preoperative and postoperative IIEF-5 scores (8.3 [s.d.: 3.9] vs 24.6 [s.d.: 0.6], P < 0.001). High treatment satisfaction was determined according to a mean EDITS score of 94.9 (s.d.: 9.9). The proposed Ghattas technique was safe and effective in our patients, and provides opportunity for cases that need a diameter larger than 13 mm. Further studies are needed to confirm these results.

Expert consensus on the bone augmentation surgery for alveolar bone defects / 口腔疾病防治

@#Alveolar bone is an important anatomic basis for implant-supported denture restoration, and its different degrees of defects determine the choices of bone augmentation surgeries. Therefore, the reconstruction of alveolar bone defects is an important technology in the clinical practice of implant restoration. However, the final reconstructive effect of bone quality, bone quantity and bone morphology is affected by many factors. Clinicians need to master the standardized diagnosis and treatment principles and methods to improve the treatment effect and achieve the goal of both aesthetic and functional reconstruction of both jaws. Based on the current clinical experience of domestic experts and the relevant academic guidelines of foreign counterparts, this expert consensus systematically and comprehensively summarized the augmentation strategies of alveolar bone defects from two aspects: the classification of alveolar bone defects and the appropriate selection of bone augmentation surgeries. The following consensus are reached: alveolar bone defects can be divided into five types (Ⅰ-0, Ⅰ-Ⅰ, Ⅱ-0, Ⅱ-Ⅰ and Ⅱ-Ⅱ) according to the relationship between alveolar bone defects and the expected position of dental implants. A typeⅠ-0 bone defect is a bone defect on one side of the alveolar bone that does not exceed 50% of the expected implant length, and there is no obvious defect on the other side; guided bone regeneration with simultaneous implant implantation is preferred. Type Ⅰ-Ⅰ bone defects refer to bone defects on both sides of alveolar bone those do not exceed 50% of the expected implant length; the first choice is autologous bone block onlay grafting for bone increments with staged implant placement or transcrestal sinus floor elevation with simultaneous implant implantation. Type Ⅱ-0 bone defects show that the bone defect on one side of alveolar bone exceeds 50% of the expected implant length, and there’s no obvious defect on the other side; autologous bone block onlay grafting (thickness ≤ 4 mm) or alveolar ridge splitting (thickness > 4 mm) is preferred for bone augmentation with staged implant placement. Type Ⅱ-Ⅰ bone defects indicate that the bone plate defect on one side exceeds 50% of the expected implant length and the bone defect on the other side does not exceed 50% of the expected implant length; autologous bone block onlay grafting or tenting techniques is preferred for bone increments with staged implant implantation. Type Ⅱ-Ⅱ bone defects are bone plates on both sides of alveolar bone those exceed 50% of the expected implant length; guided bone regeneration with rigid mesh or maxillary sinus floor elevation or cortical autologous bone tenting is preferred for bone increments with staged implant implantation. This consensus will provide clinical physicians with appropriate augmentation strategies for alveolar bone defects.

Laparoscopía de etapificación y citología peritoneal en cáncer gástrico: descripción de la técnica quirúrgica / Staging laparoscopy and peritoneal cytology in gastric cancer: technique description and review of the literature

Resumen Introducción: El cáncer gástrico continúa representando la más alta mortalidad por cáncer en hombres en Chile. En una revisión sistemática, evidenciaron que en el 59% de los pacientes que se catalogaron como M0 mediante diferentes estudios como TC, resonancia magnética y PET, se detectaron metástasis a la laparoscopia de etapificación. El objetivo de este estudio es describir la técnica quirúrgica de esta laparoscopía incluida la citología peritoneal y una revisión de la literatura en cuanto a sus indicaciones y posibilidad de cambio de conducta. Materiales y Método: Se realizó la búsqueda de artículos vía MED - LINE/PubMed (U.S.A. National Library of Medicine), Cochrane Library, Elsevier, SciELO; no se aplicó análisis estadístico, se incluyeron 23 referencias relacionadas al tema y materias afines internacionales y nacionales. El procedimiento que describiremos será la laparoscopia diagnóstica y la citología de líquido peritoneal para estudio anatomopatológico. Discusión y Conclusiones: La laparoscopía de etapificación, logra un cambio de conducta en un 20% aproximadamente de los casos, pero hacen faltan más estudios de validación de esta en los centros que tratan dicha enfermedad en el país.

Introduction: Gastric cancer continues to represent the highest mortality from cancer in men in Chile. In a systematic review, they showed that 59% of the patients who were classified as M0 by different studies such as CT, magnetic resonance imaging and PET, metastases were detected at staging laparoscopy. The objective of this study is to describe the surgical technique of staging laparoscopy including peritoneal cytology and a review of the literature regarding its indications and the possibility of behavior change. Materials and Method: Articles were searched via MEDLINE/PubMed (U.S.A. National Library of Medicine), Cochrane Library, Elsevier, SciELO, no statistical analysis was applied, 23 references related to the topic and related international and national subjects were included. The procedure to be described will be diagnostic laparoscopy and peritoneal fluid cytology for pathological study. Discussion and Conclusions: Staging laparoscopy achieve a change in behavior in approximately 20% of the cases, but more validation studies are needed in the centers that treat this disease in the country.

A new approach for hemorrhoid disease: selective dearterialization and mucopexy without doppler guidance / Uma nova opção para o tratamento da doença hemorroidária: desarterialização e mucopexia seletiva sem o ultrassom doppler

ABSTRACT Background: Transanal hemorrhoidal dearterialization (THD) is safe and effective minimally invasive treatment for hemorrhoidal disease, but reports regarding recurrence and postoperative complications (pain and tenesmus) vary significantly. Aim: To evaluate if selective dearterialization and mucopexy at the symptomatic hemorrhoid only, without Doppler guidance, achieves adequate control of the prolapse and bleeding and if postoperative morbidity is reduced with this technique. Methods: Twenty consecutive patients with grade II and III hemorrhoids were treated with this new approach and were evaluated for postoperative complications and recurrence. Results: Control of prolapse and bleeding was achieved in all patients (n=20). Postoperative complications were tenesmus (n=2), external hemorrhoidal thrombosis (n=2) and urinary retention (n=2). After a mean follow-up of 13 months no recurrences were diagnosed. Conclusion: Selective dearterialization and mucopexy is safe and achieves adequate control of prolapse and bleeding and, by minimizing sutures in the anal canal, postoperative morbidity is diminished. Doppler probe is unnecessary for this procedure, which makes it also more interesting from an economic perspective.

RESUMO Racional: O tratamento da doença hemorroidária pela técnica de THD (Transanal Hemorrhoidal Dearterialization) é minimamente invasivo e tem se mostrado seguro e eficiente. No entanto, dados sobre a recorrência e complicações (dor e tenesmo) no pós-operatório são muito variáveis. Objetivo: Avaliar se a desarterialização e mucopexia seletiva, sem o uso de Doppler, é suficiente para o controle de sintomas e se a morbidade pós-operatória é menor com esta técnica. Métodos: Vinte pacientes foram tratados com essa técnica e avaliados sobre controle de sintomas, morbidade pós-operatória e recorrência. Resultados: Controle do prolapso e sangramento foi observado em todos pacientes (n=20). Complicações pós-operatórias foram: tenesmo (n=2), trombose hemorroidária externa (n=2), retenção urinária (n=2). Após um seguimento médio de 13 meses, nenhuma recorrência foi detectada. Conclusões: O procedimento de desarterialização e mucopexias seletivas é seguro e eficiente em termos de controle do prolapso e sangramento. Esta técnica resulta em menor morbidade cirúrgica, uma vez que diminui o número de suturas no canal anal, resultando em menos dor e tenesmo pós-operatório. Para este procedimento o uso de ultrassom Doppler é desnecessário, o que diminui custos e o torna mais atrativo do ponto de vista econômico.
