Prevention has a paramount role in reducing the incidence of corrosive ingestion especially in children, yet this goal is far from being reached in developing countries, where such injuries are largely unreported and their true prevalence simply cannot be extrapolated from random articles or personal experience. The specific pathophysiologic mechanisms are becoming better understood and may have a role in the future management and prevention of long-term consequences, such as esophageal strictures. Whereas the mainstay of diagnosis is considered upper gastrointestinal endoscopy, computed tomography and ultrasound are gaining a more significant role, especially in addressing the need for emergency surgery, whose morbidity and mortality remains high even in the best hands. The need to perform emergency surgery has a persistent long-term negative impact both on survival and functional outcome. Medical or endoscopic prevention of stricture is debatable, yet esophageal stents, absorbable or not, show promising data. Dilatation is the first therapeutic option for strictures and bougies should be considered especially for long, multiple and tortuous narrowing. It is crucial to avoid malnutrition, especially in developing countries where management strategies are influenced by malnutrition and poor clinical conditions. Late reconstructive surgery, mainly using colon transposition, offers the best results in referral centers, either in children or adults, but such a difficult surgical procedure is often unavailable in developing countries. Possible late development of esophageal cancer, though probably overemphasized, entails careful and long-term endoscopic screening.

IntroductionLesions of the upper digestive tract due to ingestion of caustic agents still represent a major medical and surgical emergency worldwide. The work-up of these patients is poorly defined and no clear therapeutic guidelines are available.Purpose of the studyThe aim of this study was to provide an evidence-based international consensus on primary and secondary prevention, diagnosis, staging, and treatment of this life-threatening and potentially disabling condition.MethodsAn extensive literature search was performed by an international panel of experts under the auspices of the World Society of Emergency Surgery (WSES). The level of evidence of the screened publications was graded using the Oxford 2011 criteria. The level of evidence of the literature and the main topics regarding foregut caustic injuries were discussed during a dedicated meeting in Milan, Italy (April 2015), and during the 3rd Annual Congress of the World Society of Emergency Surgery in Jerusalem, Israel (July 2015).ResultsOne-hundred-forty-seven full papers which addressed the relevant clinical questions of the research were admitted to the consensus conference. There was an unanimous consensus on the fact that the current literature on foregut caustic injuries lacks homogeneous classification systems and prospective methodology. Moreover, the non-standardized definition of technical and clinical success precludes any accurate comparison of therapeutic modalities. Key recommendations and algorithms based on expert opinions, retrospective studies and literature reviews were proposed and approved during the final consensus conference. The clinical practice guidelines resulting from the consensus conference were approved by the WSES council.ConclusionsThe recommendations emerging from this consensus conference, although based on a low level of evidence, have important clinical implications. A world registry of foregut caustic injuries could be useful to collect a homogeneous data-base for prospective clinical studies that may help improving the current clinical practice guidelines.

Laparoscopic myotomy is as safe as BoTx treatment and is a 1-shot treatment that cures achalasia in most patients. BoTx should be reserved for patients who are unfit for surgery or as a bridge to more effective therapies, such as surgery or endoscopic dilation.

Problem An unsafe environment is a risk factor for child injury and violence. Among those injuries that are caused by an unsafe environment, the accidental ingestion of corrosive substances is significant, especially in developing countries where it is generally underreported. Approach To address this challenging, unmet medical need, we started a humanitarian programme in Sierra Leone. By reviewing the current literature from developing countries and our own experience in the field, we developed a flowchart for management of this clinical condition. Local setting This injury is underreported in developing countries. Data available are heavily skewed towards well-resourced centres and do not reflect the entire reality of the condition. Late oesophageal strictures are usually severe. Parent's lack of knowledge, crowded living conditions and availability of chemicals in and around houses account for most ingestions. The widespread lack of any preventive measures represents the strongest risk factor. Relevant changes Timely admission was observed in 19.5% of 148 patients studied. A gastrostomy was performed on 62.1% of patients, 42.8% had recurrent strictures and 19% are still on a continuous dilatation programme. Perforation and death rate were respectively 5.6% and 4%. Lessons learned The majority of oesophageal caustic strictures in children are observed late, when dilatation procedures are likely to be more difficult and carry a significantly higher recurrence rate. Gastrostomy is necessary to maintain adequate nutritional status but mothers need training in feeding techniques. Both improvement in nutritional status and sustained oesophageal patency should be the reference points to a successful dilatation.Une traduction en français de ce résumé figure à la fin de l'article.

Limited access to surgery is highly remarkable in Afghanistan, with a severe shortage of emergency surgical capacities in provincial and district hospitals, where availability of basic and emergency surgical care is far from satisfactory. A comprehensive approach for strengthening basic surgical capacities at the primary health care level should be introduced.
