Objective: To explore the indications and management of common postoperative complications of phase II tracheoesophageal puncture (TEP) for Provox Vega voice prosthesis after total laryngectomy. Methods: The clinical data of 20 patients undergoing phase II TEP for Provox Vega voice prosthesis in our hospital between May 2021 and January 2022 were analyzed. Among them, there were 19 males and 1 female, aged from 37 to 76 years, with an average age of (60.0±8.4)years. The surgical indications and the prevention and treatment of common postoperative complications were summarized. Descriptive analysis was used in this research. Results: The basic surgical indications were as following: after total laryngectomy, there was no stenosis of the stoma and esophagus entrance, no scar constitution, no mouth opening restriction, no stiffness and backward restraint of the neck after radiotherapy, and more than half a year apart surgery or radiotherapy. Among the 20 patients, 18 underwent implantation successfuly, 1 failed in the operation, and for 1 patient, the prosthesis was removed due to bleeding 1 week after implantation. The common postoperative complications included TEP fistula infection (2 cases), the TEP fistula bleeding(1 case), deep neck (prevertebral) abscess (1 case), granulation at the inner side of the TEP fistula (1 case), invagination of the prosthesis (2 cases) and leakage around the prosthesis (2 cases). All patients were cured with different interventions. Conclusions: The Provox Vega voice prosthesis is generally safe for phase Ⅱ implantatione, but implantation indications need to be established. Common postoperative complications can be solved through preventive and remedial interventions.

The oral route is started in almost half of cases between 10-12 days after surgery; the hospital stay is on average 18.5 days. Mortality is 3.70%. Conclusión: The esophageal substitution by inverted gastric tube via retrosternal ascent is a technique comparable in results to the interposition of the colon. For the authors, the stomach is an ideal organ to perform esophageal reconstruction, and its complications are manageable.

Lesão transfixante de carótida por espinha de peixe - relato de caso / Carotid artery perforation by fish bone - a case report

Abstract Accidental fish bone ingestion is a common complaint at emergency departments. The majority of cases have a benign course. However, serious complications such as esophagus perforation, cervical vessel injury and cervical abscess can occur in 7.4% of cases. Mortality rates can be as high as 50% when mediastinitis occurs. We report a case of an esophageal perforation caused by a fish bone with a lesion to the right common carotid artery after 20 days of evolution. Surgical exploration occurred with corrections of the lesion in the right common carotid and esophagus. Early identification of this kind of injury is paramount to prevent potentially fatal complications.

Conducta actual frente la hemorragia digestiva alta: desde el diagnóstico al tratamiento / Current behavior against Upper Digestive Hemorrhage: from diagnosis to treatment

Resumen La hemorragia digestiva alta (HDA) es una emergencia médico-quirúrgica común que debe ser tratada precozmente por su alta morbimortalidad. Corresponde a sangrado del esófago, estómago o del duodeno proximal, y se divide en etiología no variceal y variceal. Dentro de las no variceales destaca la úlcera péptica como la más frecuente, siendo esta producida por un desbalance entre factores protectores y agresivos. Por otro lado, en las hemorragias variceales destacan las várices gastroduodenales, las cuales son consecuencia del aumento de la presión portal. La incidencia de la HDA a nivel mundial varía entre 37 a 172 casos por cada 100.000 habitantes por año y la mortalidad entre un 5 y un 14% según diferentes estudios. Lamentablemente, no existen cifras nacionales fidedignas de incidencia y prevalencia. El médico debe conocer bien la presentación clínica y la fisiopatología para ser asertivo en la sospecha, diagnóstico y manejo de esta patología. En cuanto al tratamiento, el enfrentamiento se divide en el manejo de urgencias y luego endoscópico, puesto que la resucitación temprana intensiva puede reducir la morbimortalidad en pacientes con HDA. A continuación se hará una revisión actualizada enfocada en los aspectos más relevantes del manejo de esta patología. Se obtuvieron los datos de Pubmed y Scielo, específicamente la búsqueda de artículos originales y de revisiones sistemáticas con las palabras "hemorragia digestiva alta", "úlcera péptica", "várices esofágicas" y otras relacionadas. Los criterios usados fueron artículos preferentemente menores a 5 años de publicación en revistas científicas de alto índice de impacto.

Upper gastrointestinal bleeding (UHD) is a common medical-surgical emergency that must be treated early due to its high morbidity and mortality. It corresponds to bleeding from the esophagus, stomach, or proximal duodenum, and is divided into non-variceal and variceal etiology. Among the non-variceal, the peptic ulcer stands out as the most frequent, being this produced by an imbalance between protective and aggressive factors. On the other hand, in variceal hemorrhages gastroduodenal varices stand out, are a consequence of increased portal pressure. The incidence of HDA worldwide varies between 37 to 172 cases per 100,000 inhabitants per year and mortality between 5 to 14% according to different studies. Unfortunately, there are no reliable national statistics of incidence and prevalence. The physician must have a good understanding of the clinical presentation and pathophysiology to be assertive in the suspicion, diagnosis, and management of this pathology. Regarding treatment, the confrontation is divided into emergency management and then endoscopic, because early intensive resuscitation can reduce morbidity and mortality in patients with UHD. This is an updated review which will be focused on the most relevant aspects of the management of this pathology. Data were obtained from Pubmed and Scielo, specifically searching for original articles and systematic reviews with the words "upper gastrointestinal bleeding", "peptic ulcer", "esophageal varices" and other related words. The criteria used were articles preferably less than 5 years old in scientific journals with a high impact index.

Safety and feasibility of laparoscopic double-flap technique in digestive tract reconstruction after proximal gastrectomy for esophagogastric junction tumors larger than 5 cm / 中华胃肠外科杂志

Objective: To investigate the safety and feasibility of laparoscopic double-flap technique (Kamikawa) in digestive tract reconstruction after proximal gastrectomy for esophagogastric junction (EGJ) leiomyoma and gastrointestinal stromal tumor (GIST) with the maximum diameter >5 cm. Methods: A descriptive case-series study was used to retrospectively analyze the data of patients with EGJ leiomyoma and GIST undergoing laparoscopic-assisted proximal gastrectomy and double-flap technique (Kamikawa) at the Department of Gastrointestinal Surgery, Guangdong Hospital of Traditional Chinese Medicine from September 2017 to March 2019. All the tumors invaded the cardia dentate line, and the maximum diameter was >5 cm. After the exclusion of patients requiring emergency surgery and complicating with severe cardiopulmonary diseases, a total of 4 patients, including 3 males and 1 female with age of 29-49 years, were included in this study. After laparoscopic-assisted proximal gastrectomy, the residual stomach was pulled out of the abdominal cavity and marked with methylene blue at the proximal end 3~4 cm from the anterior wall of the residual stomach in the shape of "H". The gastric wall plasma muscular layer was cut along the "H" shape, and the space between the submucosa and the muscular layer was separated to both sides along the longitudinal incision line to make the seromuscular flap. The residual stomach was put back into the abdominal cavity. Under laparoscopy, 4 stitches were intermittently sutured at the upside of "H" shape and 4-5 cm from the posterior wall of the esophageal stump. The stump of the esophagus was cut open, and the submucosa and mucosa were cut under the "H" shape to enter the gastric cavity. The posterior wall of the esophageal stump was sutured continuously with the gastric stump mucosa and submucosa under laparoscopy. The anterior wall of the esophageal stump was sutured continuously with the whole layer of the residual stomach. The anterior wall of the stomach was sutured to cover the esophagus. The anterior gastric muscle flap was sutured and embedded in the esophagus to complete the reconstruction of digestive tract. The morbidity of intraoperative complications and postoperative reflux esophagitis and anastomosis-related complications were observed. Results: All the 4 patients completed the operation successfully, and there was no conversion to laparotomy. The median operative time was 239 (192-261) minutes, the median Kamikawa anastomosis time was 149 (102-163) minutes, and the median intraoperative blood loss was 35 (20-200) ml. The abdominal drainage tube and gastric tube were removed, and the fluid diet was resumed on the first day after surgery in all the 4 patients. The median postoperative hospitalization time was 6 (6-8) days. Postoperative pathology revealed 3 leiomyomas and 1 GIST. There were no postoperative complications such as anastomotic leakage or stenosis, and no reflux symptoms were observed. The median follow-up time was 22 (11-29) months after the operation, and no reflux esophagitis occurred in any of the 4 patients by gastroscopy. Conclusion: For >5 cm EGJ leiomyoma or GIST, double-flap technique (Kamikawa) used for digestive tract reconstruction after proximal gastrectomy is safe and feasible.

Surgical treatment of relapsed megaesophagus / Tratamento cirúrgico do megaesôfago recidivado

ABSTRACT Objective: to analyze the surgical treatment of patients with recurrent megaesophagus followed at the esophageal-stomach-duodenal outpatient clinic of the Hospital de Clínicas - UNICAMP. Methods: a retrospective study, from 2011 to 2017, with 26 patients with Chagas or idiopathic megaesophagus, surgically treated, and who recurred with dysphagia. Clinical, endoscopic and radiographic aspects were assessed and correlated with the performed surgical procedures. Results: 50% had dysphagia for liquids, 69% regurgitation, 65.3% heartburn, 69.2% weight loss and 69.2% had Chagas disease. In addition, 38.4% had megaesophagus stage 1 and 2 and 61.5% stage 3 and 4. Regarding the reoperations, 53% of them underwent Heller-Pinotti surgery by laparoscopy, Serra-Dória in 30.7% and esophageal mucosectomy in 7.9%. In 72% of the reoperations there were no postoperative complications, and 80% of the patients had a good outcome, with reduction or elimination of dysphagia. Among the reoperated patients undergoing the laparoscopic Heller-Pinotti technique, three reported little improvement of dysphagia in the postoperative period and among those who underwent Serra-Dória surgery, 100% had no dysphagia. It was observed that, when the time between the first procedure and the reoperation was longer, the better the surgical result was, with statistical significant decreased dysphagia (p=0.0013, p<0.05). Conclusions: there was a preference to perform laparoscopic re-miotomy and, as a second option, Serra-Dória surgery, for patients with recurrent megaesophagus. Esophagectomy or esophageal mucosectomy were reserved for more severe patients.

RESUMO Objetivo: analisar o tratamento cirúrgico dos pacientes com megaesôfago recidivado acompanhados no ambulatório de cirurgia de esôfago-estômago-duodeno do Hospital de Clínicas da UNICAMP. Métodos: estudo restrospectivo no período de 2011 a 2017, com 26 pacientes portadores de megaesôfago chagásico ou idiopático, tratados cirurgicamente e que evoluíram com recidiva da disfagia. Foram avaliados aspectos clínicos, endoscópicos e radiográficos, sendo correlacionados com os procedimentos cirúrgicos realizados. Resultados: 50% apresentava disfagia para líquidos, 69% regurgitação, 65,3% pirose, 69,2% perda de peso e 69,2% era chagásico. Além disso, 38,4% apresentavam megaesôfago estágio 1 e 2 e 61,5% estágio 3 e 4. Quanto às reoperações, em 53% foi realizada a cirurgia de Heller-Pinotti videolaparoscópica, seguida de Serra-Dória em 30,7% e mucosectomia esofágica em 7,9%. Em 72% das reoperações não houve complicações pós-operatórias e 80% tiveram evolução satisfatória com redução ou ausência da disfagia. Dentre os pacientes reoperados pela técnica de Heller-Pinotti videolaparoscópica, três referiram pouca melhora da disfagia no pós-operatório. Dentre os pacientes submetidos à cirurgia de Serra-Dória, 100% tiveram evolução satisfatória da disfagia. Foi observado nos pacientes com o tempo entre a primeira cirurgia e a reoperação mais longo, um melhor resultado cirúrgico com diminuição da disfagia, com relevância estatística (p=0,0013, p<0,05). Conclusão: houve preferência nas reoperações de megaesôfago pela realização de re-miotomia por videolaparoscopia e, como segunda opção, a cirurgia de Serra-Dória. A esofagectomia ou mucosectomia esofágica foram reservadas para os casos mais avançados.

Total Laryngectomy with Horizontal Mechanical Closure of the Pharyngoesophagectomy: Evaluation of the Effectiveness in Elderly Patients

Abstract Introduction The main modalities of surgical treatment for laryngeal cancer include transoral laser microsurgery (TLM), open preservation surgery, and total laryngectomy (TL). In the elderly, for the presence of comorbidities, the surgical approach more appropriate in many cases remains TL. The use of a stapler for the closure of the esophagus has been introduced to reduce surgical time and postoperative complications such as pharyngocutaneous fistula (PCF). Objective In the present study, we have evaluated the effectiveness of the use of the horizontal mechanical pharyngoesophageal closure in patients who underwent TL. Methods This nonrandomized study was performed on consecutive patients with histopathologically proven squamous cell endolaryngeal carcinoma. The TLwas performed using a linear stapler to mechanically suture the pharyngotomy using the semiclosed technique. Results A total of 33 patients underwent TL, and 13 of themunderwent neck dissection. A total of 15 patients (45.4%) were ≤70 years old, and 18 were > 70 years old. Analyzing the results in relation to age, patients > 70 years old showed tumors at an earlier stage than those aged ≤70 years old. Furthermore, in this group there was a greater number of patients who had comorbidities (p = 0.014). In total, we had 2 (6%) cases of PCF in 6.6% in the group ≤70 years old, and in 5.5% of the group > 70 years old (p = 1.00). Conclusions The use of the stapler for the horizontal closure of the pharyngoesophagectomy in the patients subjected to TL is proven to be useful and safe even when used in elderly patients.

Síndrome de Boerhaave: uma complicação rara em pós-operatório de cirurgia estética / Boerhaave syndrome: a rare complication of cosmetic surgery

Introdução: Este estudo se trata de um relato de caso que tem por objetivo alertar os cirurgiões para uma possível complicação em pós-operatório de cirurgias estéticas longas sob anestesia geral. A Síndrome de Boerhaave é uma doença grave que ameaça a vida do paciente e merece um diagnóstico precoce até 12hs e um tratamento adequado. Relato de caso: A paciente no pós-operatório de cirurgia plástica abdominal e mastopexia apresentou, após anestesia geral, crises de vômito e náuseas. Resultados: Paciente com 58 anos do sexo feminino submetida à dermolipectomia abdominal e mastopexia pela a técnica de pedículo inferior sob raquianestesia, onde após um período de quatro horas do término da cirurgia apresentou vários episódios de vômitos. Após 10 horas do ato cirúrgico apresentou queixa de algia ao deglutir, seguida de algia intensa generalizada, dispneia intensa, sudorese, palidez, PA 90x50mmhg. Com a piora do quadro a paciente foi encaminhada para a unidade de terapia intensiva onde foi entubada. Foram realizados exames laboratoriais, toracocentese e exames radiológicos. Atualmente, a paciente encontra-se com prótese esofágica. Conclusões: Fazendo a correlação com a bibliografia, no caso em tela sugere-se evitar cirurgias prolongadas, principalmente sob anestesia geral onde pode ocorrer a retenção de gás carbônico, que pode levar a crise emética no pós-operatório em pacientes com antecedentes de doença esofagiana e estar atentos aos sintomas, não descartando a possibilidade da ocorrência da Síndrome Boerhaave.

Introduction: The objective of this case report is to alert surgeons to a possible postoperative complication of long cosmetic surgery under general anesthesia. Boerhaave syndrome is a serious life-threatening disease that requires diagnosis within 12 hours and proper treatment. Case report: A 58-year-old female patient presented with vomiting and nausea after abdominoplasty and mastopexy under general anesthesia. Results: The patient underwent dermolipectomy and mastopexy using the inferior pedicle technique under spinal anesthesia. Four hours after the operation, she presented several episodes of vomiting. Ten hours after the operation, she reported painful swallowing followed by generalized severe pain and presented severe dyspnea, sweating, pallor, and a 90/50 mmHg blood pressure. As the condition worsened, the patient was referred to the intensive care unit where she was intubated and underwent laboratory tests, thoracentesis, and radiological examinations. The patient currently uses an esophageal prosthesis. Conclusions: The literature suggests avoiding prolonged surgery, especially under general anesthesia, because of the risk of carbon dioxide retention, which may lead to postoperative emetic crisis in patients with a history of esophageal disease. It also suggests paying attention to symptoms, not excluding the possibility of Boerhaave syndrome.

Pharyngo-ileo-colo-anastomosis with micro-vascular blood supply augmentation for esophago-gastric replacement due to esophago-gastric necrosis after caustic ingestion / Faringo-íleo-colo-anastomose com suprimento sanguíneo microvascular para substituição esofagogástrica por necrose esofagogástrica após ingestão cáustica

ABSTRACT Background : Complete esophago-gastric necrosis after caustic ingestion is a challenging surgical scenario for reconstruction of the upper digestive transit. Aim : To present a surgical technique for reconstruction of the upper digestive tract after total esophagectomy and gastrectomy due to esophageal and gastric necrosis Method: The transit was re-established by means of a pharyngo-ileo-colic interposition with microsurgical arterial and venous anastomosis for augmentation of blood supply. Colo-duodeno-anastomosis and ileo-transverse colic anastomosis were performed for complete digestive transit reconstruction. Result: This procedure was applied in a case of 41 years male attempted suicide by ingesting alkali caustic liquid (concentrated sodium hydroxide). Total necrosis of the esophagus and stomach occurred, which required initially total esophago-gastrectomy, closure at the level of the crico-pharyngeal sphincter and jejunostomy for enteral feeding with a highly deteriorated quality of life . The procedure was performed later and there were no major early and late postoperative complications and normal nutritional conditions were re-stablished. Conclusion: The procedure is feasible and must be managed by multidisciplinary team in order to re-establish a normal quality of life.

RESUMO Racional: A necrose esofagogástrica completa após ingestão cáustica é um cenário cirúrgico desafiador para a reconstrução do trânsito digestivo alto. Objetivo: Apresentar uma técnica cirúrgica para reconstrução do trato digestivo superior após esofagectomia total e gastrectomia por necrose esofágica e gástrica. Método: O trânsito foi restabelecido por interposição faringo-íleo-cólica com anastomose arterial e venosa microcirúrgica com aumento do suprimento sanguíneo. Adicionalmente, anastomose colo-duodeno-anastomótica e íleo-transversa foram realizadas para reconstrução completa do trânsito digestivo. Resultado: Este procedimento foi aplicado em um homem de 41 anos com tentativa de suicídio pela ingestão de líquido cáustico alcalino (hidróxido de sódio concentrado). Ocorreu necrose total do esôfago e do estômago, o que exigiu inicialmente esofagogastrectomia total, fechamento ao nível do esfíncter cricofaríngeo e jejunostomia para alimentação enteral produzindo qualidade de vida altamente deteriorada. O procedimento foi realizado mais tardiamente e não houve maiores complicações pós-operatórias precoces e tardias e condições nutricionais normais foram restabelecidas. Conclusão: O procedimento é viável e deve ser manejado por equipe multidisciplinar a fim de restabelecer a qualidade de vida normal.

Rotinas e condutas em cirurgias para as doenças malignas e benignas do esôfago, estômago e duodeno / Preoperative care in surgeries for the malignant and benign diseases of oesophagus, stomach and duodenum

Resumo: As doenças que acometem o trato digestivo alto, mais precisamente o esôfago, estômago e duodeno revestem-se de grande importância não só devido à relevância epidemiológica (com incidências elevadas e crescentes), mas também pela intensidade dos sintomas e a gravidade das complicações, comprometendo de forma significativa a qualidade de vida dos seus portadores. Nas últimas décadas, os avanços nos cuidados a pacientes portadores de doenças benignas e malignas do aparelho digestivo superior se manifestaram por meio da introdução de novos métodos de diagnóstico e estadiamento, mudanças no paradigma das estratégias perioperatórias e desenvolvimento de novos procedimentos, técnicas e vias de acesso cirúrgicos; ampliando ainda mais o espectro de opções diagnósticas e terapêuticas. Diante do amplo acesso a uma quantidade imensa de informações provida pela medicina atual, o desenvolvimento de protocolos de cuidados pré- e pós-operatórios baseados em evidências, resulta em auxílio na tomada de decisão e certamente também contribui para melhoria dos resultados cirúrgicos. Pela complexidade associada, é imperativo que o seguimento destes pacientes seja realizado em serviços terciários, muitos dos quais também se constituem em hospitais de ensino, com participação contínua de profissionais em treinamento e aprendizado. O presente projeto objetiva à elaboração de manual de rotinas e condutas específicas para o tratamento cirúrgico das doenças malignas e benignas do esôfago, estômago e duodeno; fundamentado em evidências clínicas e com aplicação em hospital de nível terciário. No contexto de hospitais universitários, de ensino e de referência ¿ que contem com equipes médicas, de enfermagem e multidisciplinares, além do envolvimento de alunos e médicos residentes em treinamento ¿ a implementação de protocolos de assistência possui relevância ainda maior, visto que não apenas diferencia e favorece melhores resultados operatórios, menor morbimortalidade e maior sobrevida em geral, mas também uniformiza condutas facilitando o processo de aprendizagem(AU)

Abstract: The diseases that affect the upper digestive tract, the esophagus, stomach and duodenum, are of great importance not only due to the epidemiological relevance (with high and increasing incidence), but also the intensity of the symptoms and the severity of the complications, compromising patients quality of life. Lately, the advances in patients care with benign and malignant diseases of the upper digestive system have consisted in the introduction of new diagnostic methods, changes in the paradigm of perioperative strategies and the development of new procedures, techniques and surgical access; expanding the spectrum of diagnostic and therapeutic options. Given the broad access to a vast amount of information provided by current medicine, the development of pre-and post-operative guidelines based on evidence, results in better decision making and certainly also contributes to improved surgical outcomes. Because of the associated complexity, it is imperative that the follow-up of these patients be performed in tertiary services, many of which also constitute teaching hospitals, with continuous participation of professionals in training and learning. The present project aims the elaboration of a guideline of specific routines and procedures for the surgical treatment of malignant and benign diseases of the esophagus, stomach and duodenum; based on clinical evidence. In the context of university, teaching and reference hospitals - which includes medical, nursing and multidisciplinary teams, as well as the involvement of students and physicians in training - the implementation of assistance protocols will have even greater influence, since it not only favors better overall survival, but also facilitates the learning process(AU)

Miotomía endoscópica por vía oral (POEM) para el tratamiento de la acalasia: experiencia clínica inicial y resultados a corto plazo / Per-oral endoscopic myotomy (POEM) for the treatment of achalasia: initial clinical experience and short term results

Resumen Introducción: La acalasia es el trastorno motor primario más frecuente del esófago. El estándar de tratamiento actual es la miotomía de Heller laparoscópica. En los últimos años, el desarrollo de técnicas endoscópicas avanzadas ha permitido el posicionamiento de la técnica POEM (del inglés: per-oral endoscopic myotomy) como una nueva alternativa terapéutica con resultados promisorios. Objetivo: Presentar nuestra experiencia clínica, con descripción de la técnica utilizada, resultados perioperatorios y seguimiento a corto plazo en el desarrollo de esta alternativa terapéutica. Materiales y métodos: Se realizó un análisis retrospectivo de datos obtenidos en forma prospectiva de 15 pacientes intervenidos mediante POEM en 3 hospitales docentes asociados. Se recopilaron variables demográficas preoperatorias, detalle del intraoperatorio y registro de morbimortalidad operatoria. Se realizó un seguimiento clínico dirigido registrando el puntaje de Eckardt y la presencia de síntomas de reflujo gastroesofágico. Resultados: Entre agosto de 2015 y noviembre de 2016 se realizaron 15 POEM. Seis de estos pacientes eran mujeres, y la edad promedio fue de 49 años. El tiempo operatorio promedio fue de 110 min; no hubo morbimortalidad operatoria. La estadía hospitalaria promedio fue de 2,8 días. El seguimiento fue de entre 1 y 15 meses. El puntaje de Eckardt promedio en el preoperatorio y en el postoperatorio fue de 10,5 y 0,4 puntos, respectivamente. Tres pacientes presentaban síntomas de reflujo gastroesofágico al momento del seguimiento. Conclusión: Los resultados obtenidos en nuestra serie apoyan la efectividad y seguridad del POEM a corto plazo. Se requiere de un seguimiento mayor para determinar el rol definitivo de esta técnica.

Abstract Introduction: Achalasia is the most common primary motor disorder of the esophagus. The current standard of treatment is laparoscopic Heller's myotomy. Recently the development of advanced endoscopic techniques has allowed the positioning of the POEM (per-oral endoscopic myotomy) technique as a new therapeutic alternative with promising results. Objective: To present our clinical experience in POEM, with description of the technique used, peri-operative results and short-term follow-up in the development of this therapeutic alternative. Materials and methods: We performed a retrospective analysis of data obtained prospectively from 15 patients undergoing POEM in three clinical centers in our country. Preoperative demographic variables, intraoperative detail, and operative morbidity and mortality were collected. Clinical follow-up was performed with controls recording Eckardt score and presence of gastroesophageal reflux symptoms. Results: Between August 2015 and November 2016, 15 POEM were performed, six of these patients were women, average age was 49 years. The average operative time was 110 min, we did not have any perioperative morbimortality. Hospital stay was 2.8 days. Follow-up was between 1 and 15 months, Eckardt's preoperative and postoperative score was on average 10.5 and 0.4 points, respectively. Three patients had gastroesophageal reflux symptoms at the time of follow-up. Conclusion: Our results support the effectiveness and security of POEM in short-term follow up. Further monitoring is required to determine the definitive role of this technique.

End-to-end versus end-to-side anastomosis in the treatment of esophageal atresia or tracheo-esophageal fistula / Anastomose terminoterminal versus terminolateral no tratamento da atresia ou fístula traqueoesofágica

Background: Dehiscence of esophageal anastomosis is frequent and there are still controversies which type of anastomosis is preferred to diminish its incidence . Aim: To compare end-to-end anastomosis versus end-to-side anastomosis in terms of anastomotic leakage, esophageal stricture and gastroesophageal reflux symptom. Methods: This study was carried out for two year starting from 2012. End-to-side and end-to-side anastomosis were compared in terms of anastomotic leakage, esophageal stricture, gastroesophageal reflux symptom, length of surgery and pack cell infusion. Results: Respectively to end-to-end and end-to-side anastomosis, duration of surgery was 127.63±13.393 minutes and 130.29±10.727 minutes (p=0.353); esophageal stricture was noted in two (5.9%) and eight (21.1%) cases (p=0.09); gastroesophageal reflux disease was detected in six (15.8%) and three (8.8%) cases (p=0.485); anastomotic leakage was found in five (13.2%) and one (2.9%) cases (p=0.203); duration of neonatal intensive care unit admission was significantly shorter in end-to-end (11.05±2.438 day) compared to end-to-side anastomosis (13.88±2.306 day) (p<0.0001). Conclusion: There were no significant differences between end-to-end and end-to-side anastomosis except for length of neonatal intensive care unit admission which was significantly shorter in end-to-end anastomosis group.

Métodos : Este estudo foi realizado por dois anos a partir de 2012. Anastomoses terminoterminal e terminolateral foram comparadas em termos de deiscência de anastomose, estenose de esôfago, sintoma do refluxo gastroesofágico, duração da operação e transfusão. Resultados : Na comparação das anastomoses terminoterminal e terminolateral, respectivamente, a duração em minutos das operações foi de 127.63±13.393 e 130.29±10.727 (p=0,353); estenose esofágica foi observada em dois (5,9%) e oito (21,1%) casos (p=0,09); doença do refluxo gastroesofágico foi detectada em seis (15,8%) e três (8,8%) casos (p=0,485); deiscência de anastomose foi encontrada em cinco (13,2%) e um (2,9%) caso (p=0,203); duração do internamento na UTI neonatal foi significativamente menor na terminoterminal (11,05±2,438 dias) em comparação com terminolateral (13,88±2,306 dias, p<0,0001). Conclusão : Não houve diferença significativa entre as anastomoses terminoterminal e terminolateral, exceto para UTI neonatal que foi significativamente menor no grupo de anastomose terminoterminal.

LATE RESULTS OF ESOPHAGOGASTRIC DEVASCULARIZATION AND SPLENECTOMY ASSOCIATED WITH ENDOSCOPIC TREATMENT IN PATIENTS WITH SCHISTOSOMIASIS / RESULTADOS TARDIOS DA DESCONEXÃO ÁZIGO-PORTAL E ESPLENECTOMIA ASSOCIADOS AO TRATAMENTO ENDOSCÓPICO PÓS-OPERATÓRIO EM PACIENTES ESQUISTOSSOMÓTICOS

Background:Schistosomiasis is endemic problem in Brazil affecting about three to four million people, and digestive hemorrhage caused by esophageal varices rupture is the main complication of the disease. Surgical treatment has become a therapeutic option, especially for secondary prophylaxis after at least one episode of bleeding. The surgical technique used by the vast majority of surgeons for the prevention of rebleeding is esophagogastric devascularization and splenectomy. Although with good postoperative results, rebleeding rate is significant, showing the need to follow-up endoscopy in all patients.Aim:To evaluate long-term results of patients submitted to esophagogastric devascularization and splenectomy and postoperative endoscopic treatment regarding esophageal varices caliber and rebleeding rates.Methods:A retrospective study of 12 patients underwent esophagogastric devascularization and splenectomy followed for more than five years.Results: All patients showed varices size reduction, and no patient had postoperative bleeding recurrence.Conclusion:Esophagogastric devascularization and splenectomy decreased significantly the esophageal variceal size when associated with endoscopic follow-up, being effective for bleeding recurrence prophylaxis.

Racional:A esquistossomose acomete três a quatro milhões de pessoas no Brasil, sendo a hemorragia digestiva por ruptura das varizes esofágicas a principal complicação da doença. O tratamento cirúrgico é empregado como profilaxia secundária em pacientes com história de hemorragia prévia. A cirurgia mais utilizada é a desconexão ázigo-portal mais esplenectomia, técnica com bons resultados, porém com índice de recidiva hemorrágica considerável, fazendo necessário o seguimento endoscópico destes pacientes.Objetivo:Analisar a evolução tardia dos pacientes no que se refere à recidiva hemorrágica e ao comportamento das varizes esofágicas quando submetidos à desconexão ázigo-portal mais esplenectomia e tratamento endoscópico pós-operatório.Método:Foram avaliados retrospectivamente 12 pacientes submetidos à desconexão ázigo-portal mais esplenectomia com acompanhamento endoscópico pós-operatório maior de cinco anos.Resultados:Todos tiveram redução significativa do calibre das varizes e nenhum paciente apresentou sangramento pós-operatório.Conclusão:A desconexão ázigo-portal mais esplenectomia diminuiu significativamente o calibre das varizes esofágicas quando associada ao tratamento endoscópico pós-operatório. Este tratamento foi efetivo para a profilaxia da recidiva hemorrágica.

Surfactant Protein A Expression in Chronic Rhinosinusitis and Atrophic Rhinitis

Introduction Surfactant protein A (SP-A) exhibits antimicrobial properties and interacts with a variety of respiratory tract pathogens. Objective The objective of this study was to detect the presence of SP-A and measure its alterations in chronic rhinosinusitis (CRS) and primary atrophic rhinitis (PAR) versus healthy controls. Methods Inferior turbinate and sinus mucosal biopsies were taken from 30 patients with CRS, 30 patients with PAR, and 20 healthy controls. Immunohistochemical staining for SP-A and polymerase chain reaction (PCR) amplification of SP-A messenger RNA were performed on nasal tissue samples. Results Immunostaining localized SP-A to the mucosa and submucosal glands in CRS specimens but failed to localize it in PAR specimens. Quantitative PCR showed a high, statistically significant increase in the SP-A levels of patients with CRS when compared with controls (p < 0.0001) and also demonstrated a significant reduction of SP-A in patients with PAR compared with controls (p < 0.005). Conclusion SP-A is significantly increased in CRS and decreased significantly in PAR and appears to be expressed by respiratory epithelial cells and submucosal glandular elements of the sinonasal mucosa. The potential therapeutic applications of surfactant in the enhancement of mucociliary clearance need to be studied. .

Perspective on Peroral Endoscopic Myotomy for Achalasia: Zhongshan Experience

Worldwide, peroral endoscopic myotomy (POEM) has achieved remarkable initial outcomes in the treatment of achalasia. In China, POEM has developed very quickly since the first case was performed in our center in August 2010. With experience, we have successfully performed POEM for special cases (such as pediatric patients, patients with sigmoid-type esophagus, and patients with recurrent symptoms after previous surgery) and have altered our technique to achieve long-term symptom remission and simplify the POEM procedure. These changes include posterior wall incision, full-thickness myotomy, a "push-and-pull" technique for myotomy, and water-jet assisted POEM. In this article, our experiences in POEM are summarized, including changes in technique, applications of the procedure, and the management of possible complications.

Hand-sewn versus stapler esophagogastric anastomosis after esophageal ressection: sistematic review and meta-analysis / Anastomose esofagogástrica manual versus mecânica pós-ressecção esofágica: revisão sistemática e metanálise

INTRODUCTION: Postoperative anastomotic leak and stricture are dramatic events that cause increased morbidity and mortality, for this reason it's important to evaluate which is the best way to perform the anastomosis. AIM: To compare the techniques of manual (hand-sewn) and mechanic (stapler) esophagogastric anastomosis after resection of malignant neoplasm of esophagus, as the occurrence of anastomotic leak, anastomotic stricture, blood loss, cardiac and pulmonary complications, mortality and surgical time. METHODS: A systematic review of randomized clinical trials, which included studies from four databases (Medline, Embase, Cochrane and Lilacs) using the combination of descriptors (anastomosis, surgical) and (esophagectomy) was performed. RESULTS: Thirteen randomized trials were included, totaling 1778 patients, 889 in the hand-sewn group and 889 in the stapler group. The stapler reduced bleeding (p <0.03) and operating time (p<0.00001) when compared to hand-sewn after esophageal resection. However, stapler increased the risk of anastomotic stricture (NNH=33), pulmonary complications (NNH=12) and mortality (NNH=33). There was no significant difference in relation to anastomotic leak (p=0.76) and cardiac complications (p=0.96). CONCLUSION: After resection of esophageal cancer, the use of stapler shown to reduce blood loss and surgical time, but increased the incidence of anastomotic stricture, pulmonary complications and mortality. .

INTRODUÇÃO: Deiscências e estenoses anastomóticas pós-operatórias são eventos dramáticos que causam aumento da morbimortalidade; por esta razão é sempre importante avaliar qual é o melhor meio de se fazer as anastomoses. OBJETIVO: Comparar as técnicas de anastomose esofagogástrica manual e mecânica, após ressecção de neoplasia maligna de esôfago, quanto à ocorrência de fístula, estenose, sangramento, complicações cardíacas e pulmonares, mortalidade e tempo cirúrgico. MÉTODOS: Foi realizada uma revisão sistemática de ensaios clínicos randomizados, que incluiu estudos de quatro bases de dados (Medline, Embase, Cochrane e Lilacs) usando a combinação dos descritores (anastomosis, surgical) and (esophagectomy). RESULTADOS: Treze ensaios clínicos randomizados foram incluídos, totalizando 1778 pacientes, sendo 889 no grupo da anastomose manual e 889 no grupo da anastomose mecânica. A anastomose mecânica reduziu o sangramento (p<0,03) e o tempo cirúrgico (p<0,00001) quando comparado à anastomose manual pós ressecção esofágica. No entanto, a anastomose mecânica aumentou o risco de estenose (NNH=33), complicações pulmonares (NNH=12) e mortalidade (NNH=33). Não houve diferença significativa em relação à formação de fístulas (p=0,76) e complicações cardíacas (p=0,96). CONCLUSÃO: Após ressecção de neoplasia esofágica, o uso da anastomose mecânica demonstrou reduzir o sangramento e o tempo cirúrgico, porém aumentou a incidência de estenose, complicações pulmonares e mortalidade. .

Step-by-step esophagojejunal anastomosis after intra-corporeal total gastrectomy for laparoscopic gastric cancer treatment: technique of "reverse anvil" / Passo a passo da anastomose esofagojejunal intra-corporea apos gastrectomia total para o tratamento do cancer gastrico por laparoscopia: padronizacao tecnica da "ogiva reversa"

Background: The laparoscopic gastrectomy is a relatively new procedure due mainly to the difficulties related to lymphadenectomy and reconstruction. Until the moment, technique or device to perform the esophagojejunal anastomosis by laparoscopy is still a challenge. So, a safe, cheap and quickly performing technique is desirable to be developed. Aim : To present technique proposed by the authors with its technical details on reconstruction with "reverse anvil". Method: After total gastrectomy completed intra-corporeally, the reconstruction starts with the preparation of the intra-abdominal esophagus cross-section next to the esophagogastric transition of 50%. A graduated device is prepared using Levine gastric tubes (nº. 14 and 10), 3 cm length, connected to the anvil of the circular stapler (nº. 25) with a wire thread (2-0 or 3-0) of 10 cm, which is connected to end of this device. The whole device is introduced in reverse esophagus. The esophagus is amputated and the wire is pulled after previous transfixation in the distal esophagus and the anvil positioned. The jejunal loop is sectioned 20-30 cm from duodenojejunal angle, and the anvil put in the jejunal loop and connect previously in the esophagus. Linear stapler (blue 60 mm) is used to close the opening of the jejunal loop. Conclusion: The "reverse anvil" technique used by the authors facilitated the transit reestablishment after total gastrectomy, contributing to obviate reconstruction problems after total gastrectomy. .

Racional: A gastrectomia laparoscópica é relativamente recente em função da dificuldade técnica relacionada à linfadenectomia e reconstrução. Até o momento, não se tem uma técnica ou dispositivo para realizar a anastomose esofagojejunal por laparoscopia que seja segura, de baixo custo e rápida execução. Objetivo : Apresentar técnica proposta pelos autores com seus detalhes técnicos de reconstrução com "ogiva reversa". Método : Após gastrectomia total completamente intra-corpórea, a reconstrução inicia-se com o preparo do esôfago intra-abdominal, com secção transversal de 50%, próximo a transição esofagogástrica. O dispositivo é preparado usando as sondas de Levine (nº.14 e 10), com 3 cm de comprimento, ligado à ogiva do grampeador circular (nº. 25) e um fio agulhado (2-0 ou 3-0) de 10 cm, ligado ao final do dispositivo que é introduzido no sentido inverso ao esôfago; ele é amputado e o fio puxado em seguida, posicionando a ogiva no esôfago distal. O jejuno a 20-30 cm do ângulo duodenojejunal é seccionado, introduzindo-se o grampeador no jejuno e conectando-o à ogiva, previamente posicionada no esôfago. Grampeador linear (azul de 60 mm) é utilizado para fechar a abertura do "cajado" do jejuno. Conclusão: A técnica de "ogiva reversa" utilizada pelos autores, facilitou a reconstrução do trânsito digestivo, contribuindo para diminuir as dificuldades técnicas na sua reconstrução após gastrectomia total. .

Gastroplasty for Esophageal Perforation after Endoscopic Balloon Dilatation for Achalasia: Two Cases

Esophageal perforation after endoscopic forceful pneumatic dilatation for achalasia is a devastating complication and surgical treatment is necessary. A 65-yr-old man and a 54-yr-old woman referred for esophageal perforation two hours after pneumatic dilatation and during the procedure, respectively. Gastroplasties through thoracotomy were performed in both cases and their recoveries were uneventful. The esophagogram with gastrografin on the post-operative 8th day did not show any passage disturbance or leakage at the anastomosis site. On the follow-up endoscopy 4 to 6 months after operation revealed that reflux esophagitis of LA classification A were noted in the both patients. They did not complain any reflux symptom or dysphagia for 9 to 13 months after operation. Instead of the most widely used procedure; primary repair of perforation site, wrapping with intercostal muscle flap and esophagomyotomy, gastroplasty was performed in two cases of iatrogenic esophageal perforation in achalasia and experienced good results.
