title: Total laparoscopic esophageal bypass using a colonic conduit for corrosive-induced esophageal stricture.
abstract: BACKGROUND
  The colon and the stomach are the most commonly used conduits for esophageal replacement in patients with esophageal strictures resulting from corrosive ingestion. The replacement surgeries have traditionally been performed by an open approach. While laparoscopic replacement surgery using a stomach conduit has been previously reported, a total laparoscopic bypass using a colonic conduit has not been previously described. We herein describe the surgical technique and results of laparoscopic esophageal bypass using a colonic conduit.
  
  
  METHODS
  Patients with corrosive stricture involving the esophagus with the proximal level at the hypopharynx, or those with concomitant gastric scarring, were selected. The surgery was performed with the patient in a supine position using five abdominal ports and a hockey stick/transverse skin crease neck incision. The main steps include colonic mobilization and assessment of the adequacy of the marginal vascular arcade, creation of a retrosternal tunnel, preparation of the colonic conduit, neck dissection, delivery of the colonic conduit into the neck and cervical pharyngo/esophagocolic anastomosis, and intra-abdominal cologastric and ileocolic anastomosis.
  
  
  RESULTS
  During the study period, 39 patients with corrosive stricture of the esophagus were managed surgically at our center with either gastric or colonic bypass. Of these, 22 patients underwent an open procedure (12 retrosternal colonic bypasses and 10 retrosternal gastric bypasses) and 17 patients underwent a laparoscopic procedure (13 retrosternal gastric bypasses and 4 retrosternal colonic bypasses). Patients with stricture at the hypopharynx (n = 2) or those in whom the stomach was contracted (n = 2) were considered for a laparoscopic esophagocoloplasty. The average duration of surgery of these latter four patients was 370 (380, 320, 360, and 420) min and the mean estimated blood loss was 100 mL. All patients could be ambulated on the first postoperative day and were allowed oral liquids by the 7th postoperative day. Compared with patients who underwent an open colonic bypass, there was significantly less need for analgesics. At a median follow-up of 5 (range 3-6) months, all patients are euphagic to solid diet and have excellent cosmetic results.
  
  
  CONCLUSIONS
  Laparoscopic colonic bypass is an achievable, safe, and effective procedure for the management of corrosive strictures of the esophagus.
