RESUMEN

Feeding of managed populations of giant anteater (Myrmecophaga tridactyla) is challenging in injured patients that present with anorexia. This report describes an approach for esophagostomy tube placement in this species. Cadavers of two adult giant anteaters were used for technique development. The animal was positioned in dorsal recumbency, and a guide feeding tube was inserted orally into the esophagus. A ventral midline incision in the midcervical region was made to access the esophagus and to protect submandibular salivary glands. The cervical musculature was dissected and retracted laterally to the right, the vagosympathetic nerve trunk was identified and preserved, and the esophagus was incised over the guide tube. The guide tube was removed to facilitate placement of the definitive tube, which was premeasured from its insertion point in the midcervical area to the level of the seventh-ninth intercostal space. The tube was secured to the cervical skin on the left side with a finger-trap suture.

RESUMEN

Background: Remnant gastric cancer (RGC) is increasing due to past use of subtotal gastrectomy to treat benign diseases, improvements in the detection of gastric cancer, and increased survival rates after gastrectomy for gastric cancer. Laparoscopic access provides the advantages and benefits of minimally invasive surgery. However, laparoscopic completion total gastrectomy (LCTG) for RGC is technically demanding, even for experienced surgeons. Because of its rarity and heterogeneity, no standard surgical strategy has been established and few surgeons will develop technical expertise to carry out this procedure. Aim: To describe our standard technique, giving surgeons a head start in LCTG and report the early experience with this stepwise approach. Materials and Methods: We detail all the steps involved in the procedure, including trocar placement and surgical description. Results: Between 2009 and 2019, a total of 8 patients with past history of RGC were operated with this technique. All patients had been previously operated by open method, 7 due to peptic ulcer disease and 1 due to gastric cancer. Their mean age at the time of the first surgery was 38.9 years (range 25-56 years) and the mean interval between the first and the second gastrectomy was 32.1 years (range 13.6-49). Billroth II was the previous reconstruction in all cases. A 5-trocar technique was used followed by total gastrectomy with side-to-side stapled intracorporeal esophagojejunostomy anastomosis and Roux-en-Y reconstruction. The mean operation time was 272 minutes (range 180-330) and median blood loss was 247 mL (range 50-500). There was no conversion and no major intraoperative complication. Major postoperative complications occurred in 3 patients. Conclusion: Completion total gastrectomy for RGC is a morbid procedure and laparoscopic access is technically feasible, hopefully carrying the benefits of faster recovery, reduced postoperative pain, and wound complications. By standardizing the approach, the learning curve may be shortened and better results achieved.

RESUMEN

Small cervical esophageal anastomotic leaks are usually treated conservatively, with considerable delays to oral feeding and a prolonged hospital stay. Self-expanding covered stents endoscopically placed are suggested as an alternative treatment. We report our hospital experience with covered stents, with good functional results but also potential morbidity.

La fístula anastomótica esofágica cervical suele manejarse de forma conservadora, lo que retrasa el inicio de la alimentación oral y prolonga la estancia hospitalaria. El uso de endoprótesis recubiertas colocadas vía endoscópica se utiliza como una alternativa para evitar esta situación. Presentamos dos casos manejados con endoprótesis recubierta, con adecuado funcionamiento pero no exenta de morbilidad.

RESUMEN

Introducción: El cáncer gástrico, es la principal causa de mortalidad masculina por cáncer en Chile. Su tratamiento, la gastrectomía total radical, se ha visto revolucionada por la introducción de la sutura mecánica, que supone disminuye la morbimortalidad y tiempo operatorio. Material y método: Estudio descriptivo. Se revisaron todas las gastrectomías totales por cáncer gástrico con sutura mecánica, realizadas en el Hospital Regional de Valdivia y se compararon con igual número realizadas con sutura manual, mediante análisis estadístico por software STATA 10.0. Resultados: Se recolectaron 45 casos, 21 con sutura manual y 24 con sutura mecánica. La edad promedio fue de 61 años para cada grupo. El sexo predominante fue el masculino. La frecuencia de fístulas de la anastomosis esofagoyeyunal fue igual en ambos grupos. Tanto el tiempo operatorio como la estadía postoperatoria también fueron similares. Conclusión: La introducción de la sutura mecánica en la anastomosis esofagoyeyunal, no ha producido un impacto importante en el descenso de la morbilidad, incluyendo la fistula anastomótica; como tampoco en la mortalidad ni en el tiempo operatorio.

RESUMEN

OBJETIVO: Descrição da técnica de esofagostomia cervical em cães com cateter de demora, para coleta de secreções e estudo de esvaziamento gástrico. MÉTODOS: A esofagostomia foi realizada em 14 animais, e os catéteres foram introduzidos até o estômago e mantidos pérveos durante oito semanas. A técnica consistiu de abertura na região lateral esquerda do pescoço para introdução do catéter, com auxilio de uma pinça tipo Mixter e a sua posterior tunelização no subcutâneo, com exteriorização na face posterior do dorso. RESULTADOS: A permeabilidade total e a utlização do catéter foi possível em 13 animais (92,8%), sendo que em um animal a obstrução foi devido acúmulo de pelos no seu interior e o cateter foi substituído. Em 3 animais (21,4%) houve a formação de pequeno abscesso na região cervical inferior, no local da primeira incisão, os quais drenaram espontaneamente. Não ocorreu nenhum acidente e o sangramento foi mínimo. Não houve mortalidade. CONCLUSÃO: A técnica descrita pode ser utilizada tanto em pesquisas semelhantes, como para alimentação de animais em experimentos do trato digestivo alto ou mesmo após operações de ressecção do esôfago e em grandes cirurgias no pescoço.

RESUMEN

PURPOSE: To describe the technique of cervical esophagostomy with indwelling catheter for the collection of secretions and study of gastric emptying. METHODS: Esophagostomy was performed in 14 dogs, and a tube was introduced into the animals' stomachs and maintained previous for eight weeks. The technique consisted of opening the left lateral surface of the neck for insertion of the tube, with the aid of a Mixter forceps, and the subsequent subcutaneous tunneling and exteriorization of the catheter on the dorsum of the animals. RESULTS: Successful use of the tube and its total permeability were observed in 13 animals (92.8%). In one animal, the tube was obstructed by hair, and it was replaced. Formation of a small abscess occurred in 3 animals (21.4%), followed by spontaneous drainage. No accidents occurred, and the bleeding was minimal. No deaths were registered. CONCLUSION: The described technique can be used in similar researches, as well as for animal feeding in investigations of the upper digestive tract, after esophageal resection and in major neck surgeries.

RESUMEN

The authors report an alternative method of cervical esophagostomy that was used in a child with type A esophageal atresia. This method involved performing a lateral esophagostomy in the proximal pouch, preserving its distal end, allowing the child to swallow normally, without choking, while stimulating the spontaneous growth of the proximal esophagus. As a result, the infant could be discharged home on G-tube feedings while waiting for spontaneous growth of the proximal pouch to occur. There were no episodes of aspiration during this period, and definitive reconstruction through end-to-end esophageal anastomosis was accomplished successfully at the age of 18 months. The authors consider that this alternative might increase the possibility of a definitive correction through delayed primary anastomosis of the infant's own esophagus in children with this type of malformation.
