Gastric conduit has emerged as the preferred treatment option for both esophageal bypass and replacement for corrosive stricture of the esophagus. There is a lack of consensus and a dearth of published literature regarding the short- and long-term complications of using a gastric conduit. This meta-analysis aims to evaluate the outcomes, morbidity, and complications associated with it.
MEDLINE, Cochrane Library, and Google Scholar (January 1960 to May 2020) were systematically searched for all studies reporting short- and/or long-term outcomes and complications following the use of a gastric conduit for corrosive esophageal stricture.
Seven observational studies involving 489 patients (53.2% males, mean age ranging from 22.1 to 41 years) who had ingested a corrosive substance (acid in 74.8%, alkali in 20.7%, and unknown in the rest) were analyzed. Gastric pull-up was performed in 56.03% (274/489) of patients. Median blood loss in the procedure was 187.5 ml with a mean operative duration of 298.75 ± 55.73 min. The overall pooled prevalence rate of anastomotic leak was 14.4% [95% CI (6.2–24.0); p < 0.05, I2 = 67.38], and anastomotic stricture was 27.2% [95% CI (13–42.8); p < 0.001, I2 = 80.11]. Recurrent dysphagia according to pooled prevalence estimates occurred in 14.4% patients [95% CI (5.4–25.1); p < 0.05, I2 = 69.1] and 90-day mortality in 4.8% patients [95% CI (1.5–9.1%); I2 = 31.1, p = 0.202]. The dreaded complication of conduit necrosis had a pooled prevalence of 1.3% [95% CI (0.1–3.4%); I2 = 0, p = 0.734].
The stomach can be safely used as the conduit of choice in corrosive strictures with an acceptable rate of complications, postoperative morbidity, and mortality.
