Surgical management of gastrointestinal bleeding.
Severe gastrointestinal bleeding has historically been a clinical problem primarily under the purview of the general surgeon. Diagnostic advances made as the result of newer technologies, such as fiberoptic and video endoscopy, selective visceral arteriography, and nuclear scintigraphy, have permitted more accurate and targeted operations. More importantly, they have led to safe, effective nonoperative therapeutic interventions that have obviated the need for surgery in many patients. Today, most gastrointestinal bleeding episodes are initially managed by endoscopic or angiographic control measures. Such interventions are often definitive in obtaining hemostasis. Even temporary cessation or attenuation of massive bleeding in an unstable patient permits a safer, more controlled operative procedure by allowing an adequate period of preoperative resuscitation. Despite the less frequent need for surgical intervention, traditional operative approaches, such as suture ligation, lesion or organ excision, vagotomy, portasystemic anastomosis, and devascularization procedures, continue to be life-saving in many instances. The proliferation of laparoscopic surgery has fostered the application of minimally invasive techniques to highly selected patients with gastrointestinal bleeding. Intraoperative endoscopy has greatly facilitated the accuracy of laparoscopic surgery by endoscopic localization of bleeding lesions requiring excision. It is anticipated that the evolving technologies pertinent to the diagnosis and management of gastrointestinal bleeding will continue to promote collaboration and cooperation between gastroenterologists, radiologists, and surgeons.
