[Surgical complications for gastric and small bowel metastases due to primary lung carcinoma]. / Complicanze chirurgiche per metastasi gastriche e digiuno-ileali da carcinoma primitivo polmonare.

ABSTRACT

Lung carcinoma is the first cause of death for tumors; in Italy there are from 35,000 to 40,000 new cases a year, with a global survival to 5 years from the diagnosis in 13% of cases. The gastric and small bowel metastases are rare, respectively 0.4% and 1.1% and the cases reported in the literature are rare. There is often a poor symptomatology and diagnosis is usually based on post-mortem examination. Yet, sometimes, the first and only demonstration of the secondary illness is a surgical complication, whether it be a haemorrhage, a perforation or an occlusion. The authors report their experience, from April 1999 to March 2003, of 3 cases of small bowel metastases, presented in 1 case with a perforation and in 2 cases with an occlusion and of 1 case of gastric metastasis, which presented with a haemorrhage. These patients were treated by emergency surgery, with 1 case only of postoperative mortality. The 1st patient died 6 months after surgery, and the 2nd patient 6 days after, the 3rd patient 4 months after the 1st operation and the 4th patient is still in follow-up after 6 months. The authors present a review of the literature and some considerations of diagnosis and surgical treatment.
