Gastrocele complicates the course of non-operated severe caustic injuries: operative strategies.

BACKGROUND: For selected cases of severe caustic injuries, evidence favors conservative management, consisting of radiographic and clinical observation without emergency surgery. However, this approach can lead to the development of gastric distension caused by combined esophageal and antral strictures, called gastrocele. This study assessed the safety of a two-stage surgical treatment for gastrocele. METHODS: Patients treated in our department between 2004 and 2010 for caustic injury who did not receive emergency surgery and subsequently developed gastrocele were retrospectively analysed. Demographic information, symptoms, and ingestion history were documented. Surgical management included partial gastrectomy and postponed esophageal stricture treatment. Outcome measures included postoperative morbidity and mortality. RESULTS: Eight nonoperated patients with severe caustic injury from suicidal ingestions of caustic substances were found to have developed gastrocoele. They presented with mostly endoscopic stage IIIb esophageal and gastric injuries. All patients had clinical symptoms of vomiting and abdominal tenderness at day 8 after caustic ingestion. Antrectomy and esophageal stricture treatment were performed at an average of 2 and 8 months, respectively, after caustic ingestion. There were no postoperative deaths, and the long-term survival rate was 83 %. CONCLUSIONS: Gastrocele should be suspected in patients with stage III gastric and esophageal injuries who have been treated by conservative management and are still vomiting more than 1 week postingestion. A two-staged surgical strategy of antrectomy followed by a postponed esophageal stricture treatment was found to be safe and effective for these patients.

The conservative management of severe caustic gastric injuries.

OBJECTIVE: To determine the safety of a conservative approach to treating severe caustic injury in patients lacking clinical and biochemical signs of transmural necrosis. BACKGROUND: Esophagogastrectomy is thought to limit the progression of severe caustic injury in the upper gastrointestinal tract observed upon initial endoscopic examination. However, endoscopic evaluation of the depth and spread of necrosis is challenging and may lead to unnecessary gastrectomy. METHODS: From January 2002 to December 2008, 70 patients were classified as having stage III gastric injury in an initial digestive tract endoscopic examination. When patients had no signs of peritonitis, their treatment was determined by 6 clinical and biochemical factors of severity (abdominal rebound tenderness, neuropsychiatric troubles, cardiovascular shock, metabolic acidosis, disseminated intravascular coagulation, and kidney failure) in addition to endoscopic staging. If one of these clinical and biochemical factors was present, the patient underwent emergency laparotomy. Patients with isolated stage III gastric injury were kept under close observation. RESULTS: Twenty-four of the 70 endoscopic stage III patients required emergency surgery. Conservative treatment was initiated in the remaining 46. There were 4 postoperative deaths (5.7%). Fifteen patients required subsequent surgery: distal gastrectomy with Billroth I anastomosis (n = 7) for distal stricture and esophagoplasty for nondilatable esophageal stricture (n = 8). At the end of the follow-up period, total or partial gastric conservation was achieved in all 46 patients (65.7%) and the esophagus was conserved in 38 patients (54.3%). CONCLUSION: In the absence of clinical and biological signs of severity, conservative management of stage III gastric injury is clinically feasible, precludes gastrectomy and has a low mortality rate.
