Risk factors in relation to postoperative complications in patients undergoing esophagectomy or gastrectomy for cancer.
To clarify the risk factors contributing to postoperative complications in the elderly patients (over 70 years) undergoing esophagectomy and/or gastrectomy, 364 patients with primary cancer seen were evaluated. As a result, some characteristic patterns of stress response in the elderly could be detected as follows: the disorders of the vital organs were more important indices for the development of postoperative complications rather than age, and a reduction in the maximum response of the stress hormones to surgical procedures in aged patients was noted; moreover, the functional variability of target organ in the aged group was confirmed. Studies on the hormonal response to surgery suggest that the restriction of fluid replacement is advisable until the third postoperative day, maintaining the host on the dry side, to prevent cardiopulmonary complications. As the nutritional status in the patients with esophageal and gastric cancer goes from bad to worse with the advancing clinical stages, adequate perioperative nutrition is imperative to prevent complications such as anastomotic leakage, wound dehiscence, and/or infections. For the treatment of anastomotic leaks after esophagectomy and esophagogastrectomy, more than 45 kcal/kg/d must be provided, and the serum albumin level must be restored to 3.5 g/dL in order to achieve spontaneous healing of small anastomotic leakages.
