Background:Among the anastomoses of the gastrointestinal tract, those of the esophagus
are of special interest due to several anatomical or even general
peculiarities. Aim:Evaluate retrospectively the results comparing mechanical vs. manual suture
at cervical esophagogastric anastomosis in megaesophagus treatment. Methods:Were included 92 patients diagnosed with advanced megaesophagus with clinical
conditions to undergo the surgery. All underwent esophageal mucosectomy,
performing anastomosis of the esophagus stump with the gastric tube at the
cervical level. In order to make this anastomosis, the patients were divided
into two groups: group A (n=53) with circular mechanical suture, lateral
end; group B (n=39) with manual suture in two sides, lateral end. In the
postoperative period, an early evaluation was performed, analyzing local and
systemic complications and late (average 5.6 y) analyzing deglutition. Results:Early evaluation: a) dehiscence of esophagogastric anastomosis n=5 (9.4%) in
group A vs. n=9 (23.0%) in group B (p=0.0418); b) stenosis of
esophagogastric anastomosis n=8 (15.1%) in group A vs. n=15 (38.4%) in group
B (p=0.0105.); c) pulmonary infection n=5 (9.4%) in group A vs. n=3 (7.6%)
in group B (p=1.0000.); d) pleural effusion n=5 (9.4%) in group A vs. n=6
(15.4%) in group B (p<0.518). Late evaluation showed that 86.4-96% of the
patients presented the criteria 4 and 5 from SAEED, expressing effective
swallowing mechanisms without showing significant differences among the
groups. Conclusion:Cervical esophagogastric anastomosis by means of mechanical suture is more
proper than the manual with lower incidence of local complications and, in
the long-term evaluation, regular deglutition was acquired in both suture
techniques in equal quality.
