Introduction and objective: neoplasic stenoses of the left colon are most f
requently caused by primary colon carcinoma, infiltration from an external
tumour and great adenomatous polyps. These patients often develop obstructi
on as their first symptom, leading to emergency surgical procedures in adve
rse circumstances and without an appropriate intestinal preparation that mi
ght prevent primary anastomosis. Therapeutic options for this event, such a
s Hartmann's resection, subtotal colectomy or anterograde colon lavage are
not always possible, in these patients a colostomy is performed that requir
es future reoperation for reconstruction of the intestinal transit. Transtu
moral self-expandable stenting followed by elective surgery might be the be
st option in these cases, as well as an alternative to surgery in non-opera
ble patients.
Patients and methods: twenty four patients treated with this procedure in t
he past four years were divided in two groups. in group 1 (14 patients), th
e stent was placed as a permanent and palliative measure for the management
of the disease. In group 2 (10 patients), the stent was placed temporarily
for the management of the intestinal obstruction and latter the patients u
nder went elective surgery with fully preoperative and extension study and
an appropriate preparation of the colon in order to allow reliable primary
anastomosis.
Results: there were no hospital mortality nor stent migrations. There was o
nly one complication (perforation caused by the stent) that required emerge
ncy surgery, but with any further complications. Failure to place the stent
occurred in one patient.
Conclusions: self-expandable stents relieve neoplasic colon obstructions an
d allow to complete the study protocol, followed by elective surgery associ
ated to less morbi-mortality, In patients with advanced or irresectable can
cer, they provide a palliative and safe alternative to surgery, with satisf
actory results.
