Academic literature on the topic 'Gastrostomy/contraindications'

Percutaneous endoscopic gastrostomy has been a valuable tool in nutritional rehabilitation since its inception in 1980. Although it was originally described in children, a large sector of the adult population is dependant on it for nutritional support. Percutaneous endoscopic gastrostomy tube insertion is generally a safe procedure. Nevertheless, variable incidence rates of complications have been reported. The present review highlights the up-to-date indications, contraindications and complications of percutaneous endoscopic gastrostomy in children, along with a discussion of issues that need further exploring through future research.

It is no exaggeration to say that percutaneous gastrostomy has revolutionized the feeding of disabled patients with intact gastrointestinal tracts. The most common indication is inability to swallow. It is generally best to place a gastrostomy tube early to prevent malnutrition and minimize complications of procedures on poorly nourished tissue. If a patient is expected to live for only weeks to months, nasoenteric feedings are the nutritional route of choice. Contraindications to percutaneous gastrostomy include coagulation disorders, upper gastrointestinal fistulas, intestinal obstruction, varices, peritoneal dialysis, septicemia and esophageal obstruction. Three techniques are described: 'pull,' 'push' and 'introducer.' The most frequently reported complications are wound infection and pneumoperitoneum. Now that multiple methods for successful insertion of endoscopic percutaneous feeding tubes have been described, the literature appears to be concentrating on complications of the various techniques. Nevertheless, compared to the other options available for patients unable to swallow (allowing malnutrition to proceed, tube feeding, surgical gastrostomy, parenteral nutrition), percutaneous gastrostomy is the procedure of choice in virtually all cases if the intestine is functioning.

AbstractPercutaneous transesophageal gastric (PTEG) tube placement is an alternative method of gastric access for feeding or decompression in patients with contraindications to conventional gastrostomy tube placement such as peritoneal carcinomatosis, gastric wall tumors, ascites, or intervening organs. PTEG tube placement is safe with a high technical success rate and it can be placed with supplies available in most interventional radiology departments using ultrasound and fluoroscopic guidance. PTEG tubes are highly efficacious at reducing symptoms in patients with malignant bowel obstruction as an alternative to long-term nasogastric decompression.

Over the last 20 years there has been great progress regarding total parenteral nutrition and enteral nutrition for patients who cannot take food by mouth or cannot swallow, or so that controlled feeding can be established in anorexic and malnourished patients. The use and the role of artificial nutrition is still controversial in advanced cancer patients. Such controversies often are due to the fact that these patients have a survival expectancy that varies from one to several months. The present review describes the most frequent techniques used for enteral nutrition (nasoenteral tubes, gastrostomy and jejunostomy), their indications, contraindications and complications, and gives an indication regarding which patients may really benefit from enteral nutrition taking into consideration not only the potential advantages but also the discomfort and distress related to enteral nutrition and the different techniques that are employed.

For patients who are unable to meet their nutritional needs orally, enteral feeding via a percutaneous approach has become the mainstay of therapy. However, traditional enteral feeding methods, such as percutaneous endoscopic gastrostomy, may not be viable options for patients with severe gastroparesis or gastric outlet obstruction. Direct percutaneous endoscopic jejunostomy (DPEJ) is an enteral access method that was first described more than 20 years ago and has gained popularity among gastroenterologists. This review discusses the indications for and contraindications to DPEJ, the procedure, the application of DPEJ in specific subsets of patients with gastrointestinal disorders, and presents a brief tabular summary of complications and success rates of DPEJ in case series published since 2000.BACKGROUND: Direct percutaneous endoscopic jejunostomy (DPEJ) is a well-known approach to deliver postpyloric enteral nutritional support to individuals who cannot tolerate gastric feeding. However, it is technically difficult, and some case series have reported significant procedural failure rates. The present article describes current indications, successes and complications of DPEJ placementMETHODS: A MEDLINE database search was performed to identify relevant articles using the key words “direct percutaneous endoscopic jejunostomy”, “percutaneous endoscopic gastrostomy”, and “percutaneous endoscopic gastrostomy with a jejunal extension tube”. Additional articles were identified by a manual search of the references cited in the key articles obtained in the primary search.RESULTS: DPEJ is gradually becoming more common in the treatment of patients who cannot tolerate gastric feeding. Differences in patient selection and technique modifications may contribute to the various success rates reported. Failure is most often due to inadequate transillumination or gastroduodenal obstruction. Currently, there are limited data to evaluate the safety and effectiveness of DPEJ.CONCLUSION: The clinical use of DPEJ is increasing. With appropriate care and expertise, DPEJ may prove to be reliable and safe.

OBJECTIVE Intrathecal baclofen infusion systems to manage severe spasticity and dystonia are associated with higher infection rates in children than in adults. Factors unique to this population, such as poor nutrition and physical limitations for pump placement, have been hypothesized as the reasons for this disparity. The authors assessed potential risk factors for infection in a multivariate analysis. METHODS Patients who underwent implantation of a programmable pump and intrathecal catheter for baclofen infusion at a single center between January 1, 2000, and March 1, 2012, were identified in this retrospective cohort study. The primary end point was infection. Potential risk factors investigated included preoperative (i.e., demographics, body mass index [BMI], gastrostomy tube, tracheostomy, previous spinal fusion), intraoperative (i.e., surgeon, antibiotics, pump size, catheter location), and postoperative (i.e., wound dehiscence, CSF leak, and number of revisions) factors. Univariate analysis was performed, and a multivariate logistic regression model was created to identify independent risk factors for infection. RESULTS A total of 254 patients were evaluated. The overall infection rate was 9.8%. Univariate analysis identified young age, shorter height, lower weight, dehiscence, CSF leak, and number of revisions within 6 months of pump placement as significantly associated with infection. Multivariate analysis identified young age, dehiscence, and number of revisions as independent risk factors for infection. CONCLUSIONS Young age, wound dehiscence, and number of revisions were independent risk factors for infection in this pediatric cohort. A low BMI and the presence of either a gastrostomy or tracheostomy were not associated with infection and may not be contraindications for this procedure.

O câncer de cabeça e pescoço é a quinta neoplasia mais frequente nos países em desenvolvimento. A disfagia resultante da doença ou do tratamento pode levar à perda ponderal e à desnutrição. A nutrição enteral por sonda é o método de escolha para administração de terapia nutricional aos pacientes com trato gastrointestinal funcionante, incapazes de manter ingestão adequada por via oral. Sondas nasogástricas ou nasoenterais são empregadas para alimentação a curto prazo e sondas de gastrostomia ou jejunostomia, para períodos de tempo mais prolongados que 4 semanas. A gastrostomia endoscópica percutânea é o método mais utilizado, dada sua segurança e eficácia. A técnica de tração é a mais comumente empregada e consiste na introdução da sonda na câmara gástrica através da via orofaríngea e com auxílio do endoscópio. Em pacientes com câncer de cabeça e pescoço, esta técnica apresenta limitações decorrentes da estenose da via digestiva provocada por inflamação, irradiação prévia ou pelo próprio tumor que impede a passagem do aparelho ou da sonda. Nesta situação, reporta-se insucesso em cerca de 20% dos casos, além de complicações decorrentes da necessidade de dilatação da estenose, infecção do local da ostomia, obstrução aguda da via aérea e até implante do tumor no local da punção na parede abdominal. A gastrostomia endoscópica percutânea pela técnica de punção é a alternativa mais segura para esse grupo de pacientes, já que a sonda é colocada por via abdominal sob controle endoscópico. As desvantagens da técnica são o risco de deslocamento do estômago insuflado no momento da punção e a utilização de sonda de menor calibre. A introdução da gastropexia endoscópica permite a fixação do estômago à parede abdominal, evitando o deslocamento gástrico no momento da punção. Ainda assim, resta o problema do calibre da sonda. O objetivo deste estudo foi avaliar a modificação de dispositivo para gastrostomia endoscópica percutânea pela técnica de punção quanto à exequibilidade, segurança, eficácia do procedimento e mortalidade. Trinta pacientes com câncer de cabeça e pescoço (a idade média de 58 anos e 76,7% do sexo masculino) foram admitidos no estudo. O índice de Karnofsky médio foi de 67,7 e o risco anestésico, ASA 1 = 3,3%, ASA 2 = 50% e 46,6%, ASA 3. O método de traqueostomia havia sido realizado na metade dos pacientes, 18 (60%) tinham sido submetidos à quimioterapia e radioterapia associadas ou isoladamente. Os tumores da cavidade oral foram os mais frequentes, com 11 (36,7%) casos. Metade dos pacientes foi diagnosticada no estádio IV da doença, 7 (23,3%) no estádio III, 1 (3,3%) estádio II e 5 (16,7%) apresentavam recidiva. O tipo histológico mais comum foi o carcinoma escamocelular, em 27 (89,9%) casos. A presença de estenose foi encontrada em 23 (76,7%) pacientes, sendo 15 (50%) isoladas e em 8 (26,7%), associadas a trismo. Os pacientes foram submetidos à gastrostomia endoscópica percutânea pela técnica de punção com dispositivo modificado com fenda lateral e mandril com ponta cônica, associada à gastropexia e colocação de sonda balonada de 20 Fr. O procedimento foi realizado em regime ambulatorial em 26 (86,7%) pacientes, sempre sob sedação e anestesia local. A via mais frequente de acesso à câmara gástrica foi a oral em 26 (86,7%) pacientes e a nasal, nos demais. Não houve necessidade de dilatação da via aerodigestiva para passagem do endoscópio. O procedimento foi bem-sucedido em todos os enfermos e sem complicações perioperatórias. Os pacientes foram seguidos no pós-operatório imediato, com 72 horas, 10, 30 e 60 dias, para avaliação de dor, infecção do estoma, funcionalidade, problemas com a sonda e mortalidade. Não foram observados sinais de infecção do estoma por meio do escore combinado de infecção. No pós-operatório imediato, um (3,3%) paciente apresentou dor abdominal difusa, levando-o à laparotomia exploradora. Tratou-se de pneumoperitoneo maciço sem sinais de lesão de outras vísceras que o justificassem e foi considerada complicação maior precoce. A maioria dos pacientes apresentou dor leve e moderada no pós-operatório imediato e com 72 horas. Duas complicações menores (6,6%) foram observadas; dermatite química por extravasamento ao redor da sonda no 36º pós-operatório e perda inadvertida de sonda no 8º pós-operatório, sem sinais de complicação e que foi reposicionada sem necessidade de nova endoscopia. Em dois (6,6%) pacientes, houve rotura tardia do balão da sonda que foi substituída, sem exame endoscópico. A infusão da dieta foi considerada de fácil execução em todos os pacientes e não houve obstrução da sonda até 60 dias de avaliação. Não se observou mortalidade relacionada ao procedimento decorridos 30 dias da intervenção. Houve dois (6,6%) óbitos entre 30 e 60 dias, decorrentes da evolução da doença. Em conclusão, a modificação do dispositivo para gastrostomia endoscópica percutânea pela técnica punção é exequível, segura e eficiente em pacientes com neoplasia avançada e obstrutiva de cabeça e pescoço, sob regime ambulatorial e sedação, permitindo o uso de sonda mais calibrosa e sua troca sem necessidade de nova endoscopia, apresentando baixas taxas de complicações e sem mortalidade relacionada ao procedimento nesta série
Head and neck cancer is the fifth most frequent neoplasm in developing countries. Dysphagia resulting from head and neck cancer or its treatment may lead to weight loss and malnutrition. Enteral nutrition is the method of choice of therapy to patients with preserved gastrointestinal tract unable to maintain adequate oral ingestion. Nasogastric or nasoenteral tubes are employed for short-term feeding and gastrostomy or jejunostomy tubes for more than 4 weeks. Percutaneous endoscopic gastrostomy is the most used method due to its safety and efficacy. The pull technique is the most commonly used method consisting in the introduction of a tube into the inflated stomach through the oropharingeal route with endoscopic aid. In those patients, such technique presents limitations due to digestive tract stenosis caused by inflammation, irradiation, or the tumor itself preventing endoscope or tube passage. In this case, failure occurs in approximately 20% of cases. Complications caused by stenosis dilation, infection of the ostomy site, acute airway obstruction, and even implantation of tumor at the puncture site on the abdominal wall have also been reported. Percutaneous endoscopy gastrostomy through introducer technique is the safest alternative for this group of patients because the tube is placed through an abdominal access under endoscopic control. The disadvantages of this method are the risk of displacing the inflated stomach at the moment of puncture and the use of smaller caliber tubes. The advent of the endoscopic gastropexy enables the fixation of the stomach to the abdominal wall preventing gastric displacement at the moment of puncture. Even though, tube caliber problem remains. The aim of this study was to evaluate the modification of a percutaneous endoscopy gastrostomy device with introducer technique regarding procedure feasibility, complications, procedure safety efficacy, and mortality. Thirty patients (mean age: 58 years, 76.7%: male) were included in the study. Mean Karnofsky index was found to be 67.7% and anesthetic risk ASA 1 = 3.3%, ASA 2 = 46.6%, and ASA 3 = 46.6%. Half of the patients had already undergone tracheostomy and 18 (60%) had chemotherapy and radiotherapy associated or in monotherapy. Oral cavity tumors were the most frequent totaling 11 (36.7%) of cases. Half of the patients were diagnosed in the stage IV of the disease, 7 (23.3%) in stage III, 1 (3.3%) in stage II, and 5 (16.7%) had already recurrence. Squamous cell carcinoma was the most frequent histological type in 27 (89.9%) of cases. Stenosis was found in 23 (76.6%) of cases, of which 15 (50%) were found to be isolated and 8 (26.7%), associated to trismus. Patients underwent introducer technique percutaneous endoscopy gastrostomy using modified device, associated to gastropexy, and a 20-Fr balloon tube placement. The procedure was performed in 26 (86.7%) outpatients under sedation and local anesthesia. The most frequent route to the inflated stomach was the oral route in 86.7% of patients and the nasal route in the others. There was no need for digestive dilation for passing the endoscope. The procedure was successful in all cases with no perioperative complications. Patients were followed up in the immediate postoperative period and at 72 hours, 10, 30 and 60 days for the assessment of pain, stoma infection, functionality, tube-related problems, and mortality. No signs of stoma infection were observed through the combined infection score. In the immediate postoperative period, one (3.3%) patient presented diffuse abdominal pain, leading to exploratory laparotomy that revealed massive pneumoperitoneum with no related signs of lesion to other organs and that was considered a major early complication. The majority of patients presented mild, moderate pain in the immediate postoperative period and at 72 hours. Two minor complications (6.6%) were observed: chemical dermatitis due to leakage around the tube on postoperative day 36 and inadvertent tube loss on postoperative day 8 with no signs of complication, so that the tube was repositioned without endoscopy. Two patients (6.6%) presented late rupture of tube balloon that was replaced without endoscopic examination. Dietary infusion was considered to be easily performed in all patients and no tube obstruction up to 60 assessment days was observed. Procedure-related deaths were not observed up to 30 days post intervention. There were two (6.6%) deaths between days 30 and 60 resulting from disease evolution. In conclusion, the application of the modified device for percutaneous endoscopy gastrostomy with introducer technique is feasible, safe, and efficient in outpatients with advanced, obstructive head and neck cancer under sedation, allowing the use of larger caliber, replaceable tube with low complication rates and no procedure-related mortality in this series
