[Suture of the submucosa in large intestine anastomosis]. / Naht der Submucosa bei der Dickdarmanastomose.

A comparison of three different suture techniques on the large bowel of the same experimental animal demonstrated that careful suture alone is adequate to produce a sufficient anastomosis. The advantages of this suture technique are to provide strength to the intestinal anastomosis, less scar tissue, and fewer peritoneal adhesions. The experimental results suggest that suturing of the submucosa can be used on other intestinal areas, too.

[Visualization of the thoracic duct during surgical operations (author's transl)]. / Intraoperative Darstellungsmöglichkeiten des Ductus thoracicus.

Anaesthetists generally object, because of the risk of aspiration, to the pre-operative administration of coloured cream for visualizing the thoracic duct during surgical operations on the oesophagus, lung hilus and major vessels of the mediastinum. The possibility was, therefore, studied to mark the thoracic duct without involving the digestive tract. The following method was developed: a dye was injected into the wall of the distant portion of the oesophagus; the dye passes into the lymphatics and is transported first into the abdominal vessels and subsequently into the thoracic duct. Six dyes were tested in animal experiments. Evans blue and patent blue proved suitable.
