Wrapping of the omental pedicle flap around esophagogastric anastomosis after esophagectomy for esophageal cancer. Use of pedicled omentum in esophagogastric anastomosis for prevention of anastomotic leak.
Esophagogastrectomy for esophageal cancer is the standard surgical treatment as a curative measure or for palliation. Esophagogastric anastomotic leakage and stricture are common life-threatening postoperative complications (more so if the leakage occurs in the chest), and the success of the anastomosis created in the reconstruction of the resected esophagus can highly influence morbidity and mortality.
                A prospective, randomized study was undertaken on 291 patients treated for carcinoma of the esophagus between January 2004 and December 2008. The study excluded 36 patients (12%) who were inoperable. Patients were assigned to 2 treatment groups that consisted of 128 patients in group A and 127 patients in group B according to a restricted, permuted block randomization plan. Patients in group A underwent an esophagogastrectomy with wrapping of the pedicle omental flap around the esophagogastric anastomosis. Group B patients underwent an esophagogastrectomy with only a stapled technique.
                Of all 255 patients who received an esophagogastric anastomosis, 226 (89%) were discharged from the hospital within 15 days of operation. There was no significant difference between these 2 groups in regard to the incidence of pulmonary complications, abdominal or thoracic infections, and days of hospital stay. Anastomotic leaks occurred in a single patient from group A (1%) and in 7 patients from group B (6%). In group A, 33 patients underwent transhiatal esophagogastrectomy and 95 had thoracic esophagogastrectomy, which resulted in an anastomotic leakage in 1 (3%) and 0 (0%) patients, respectively. In group B, 42 patients had transhiatal esophagogastrectomy and 85 had thoracic esophagogastrectomy, which resulted in anastomotic leakage in 5 (12%) and 2 (2%) patients, respectively. The leakage ratio of group B was significant greater than that of group A (P < .05). Two patients were excluded during the evaluation of the benign stricture due to hospital mortality. Anastomotic strictures were noted in 8 patients from group A (6%) and 20 patients from group B (16%), and the difference in the incidence of anastomotic strictures between these 2 groups was statistically significant (P < .05).
                Wrapping of the pedicle omental flap around the esophagogastric stapled anastomosis site decreases the incidence of anastomotic leakage and stricture rate after esophagectomy for esophageal cancer, thereby decreasing the morbidity and mortality of the procedure.

                A prospective, randomized study was conducted on 238 patients treated for carcinoma of the esophagus between January 2000 and January 2006. The study excluded 44 patients (18.49%) who were inoperable. The patients were assigned to two treatment groups of 97 each (A and B) according to a restricted permuted block randomization plan. Group A patients underwent esophagogastrectomy with wrapping of the pedicled omentum around the esophagogastric anastomosis. Group B patients underwent esophagogastrectomy without using the omental graft. An Ivor-Lewis type esophagogastrectomy (TTE) was done in 122 patients (62.89%) and a transhiatal esophagogastrectomy (THE) was done in 72 (37.11%).
                Anastomotic leaks occurred in 3 group A patients (3.09%) and in 14 (14.43%) group B patients. In group A, 54 patients underwent THE and 43 had TTE, with anastomotic leakage in 2 (3.70%) and 1 (2.33%) patients, respectively. In group B, 48 patients had THE and 49 had TTE, with anastomotic leakage in 8 (16.26%) and 6 (12.24%), respectively. The difference in the incidence of leakage was statistically significant (p = 0.005). There was no complication related to the omental graft technique nor was there a significant difference in the mortality between the two groups.
                The pedicled omental transposition for reinforcing the anastomotic suture line significantly reduces the incidence of leakage after esophagogastrectomy for carcinoma of the esophagus, thus decreasing the morbidity and mortality of the procedure.
Omentoplasty may provide an additional benefit to decrease the incidence of anastomotic leakage after esophagectomy and esophagogastrostomy for esophageal cancer patients without increasing or decreasing other complications, especially for those patients treated with THE. Further randomized controlled trials are still needed to investigate the influences of omentoplasty in different operation procedures of esophagectomy and esophagogastrostomy on the incidence of anastomotic leakage, anastomotic stricture, long-term survival rate and quality of life after esophagectomy and esophagogastrostomy.
