RESUMO
PURPOSE: Caustic ingestion is a potential life-threatening condition associated with high morbidity and mortality. Data on patients admitted to Intensive Care Unit (ICU) for severe caustic ingestion are lacking. We aimed to describing epidemiological features and outcomes of patients admitted to ICU for caustic ingestion in France. METHODS: In a retrospective, observational, and multicenter study, data from the national French Programme de Médicalisation des Systèmes d'Informations (PMSI) database were analysed from 2013 to 2019. In-hospital mortality rate (primary outcome) and in-ICU complications (secondary outcomes) were reported and analysed. RESULTS: 569 patients (289 males (50.8%), with median age of 49 years [interquartile (26-62)] were admitted in 65 French ICU for severe caustic ingestion. Five hundred and thirteen patients (90%) were admitted for intentional caustic ingestion. The median length of stay in ICU was 14.0 [4.0-31.0] days. In-hospital mortality occurred in 56 patients (9.8%). In multivariate analysis, age and simplified acute physiology score II were associated with in-hospital mortality age of 40-59 years [OR = 15.3 (2.0-115.3)], age of 60-79 years [OR = 23.6 (3.1-182.5)], and age > 80 years [OR = 37.0 (4.2-328.6)] and SAPS 2 score [OR = 1.0018 (1.003-1.033), p < 0.001]. During ICU stay, 423 complications (74%) were reported in 505 patients (89%). Infectious (244 (42.9%)), respiratory (207 (36.4%)), surgical 62 (10.9%), haemorrhagic (64 (11.2%)) and thrombo-embolic and (35 (6.2%)) complications were the most frequently reported during ICU stay. CONCLUSION: ICU admission for severe caustic ingestion is associated with 9.8% mortality and 74% complications. Age > 40 years and SAPS 2 score were independently associated with mortality.

Liquefied petroleum gas (LPG) is a widely used environment-friendly fuel. Previous studies have shown an increasing number of LPG-related burns. Our study was designed to evaluate the epidemiologic pattern of these injuries and provide recommendations for burn prevention. This retrospective study included all patients with LPG-related burns from eight burn centers in Zhejiang Province, China between 2011 and 2015. Database variables included patient demographics, accident characteristics, and injury characteristics. The association between different categorical variables was identified using the chi-square test. And the association between two or more means of quantitative variables was analyzed by the one-way analysis of variance or t-test. A total of 1898 patients were included, 47.31% were males and 52.69% were females. The predominant age group was 31 to 70 years (74.50%), and the majority were poorly educated and the incidence peaked from June to September. The most common place of occurrence was home (74.08%) and gas leak (96.52%) was the most common cause. The four limbs (43.33%) were the most frequently affected areas; the mean burn area was 25.19 ± 20.97% of the total body surface area and most patients (46.89%) suffered from moderate burns. The mean length of hospital stay was 17.66 ± 16.55 days and the majority of patients (89.36%) recovered with a 0.84% mortality rate. Our findings reflected that the increase in incidence rate was alarming, and the causes resulting in LPG-related burns have not gained much attention yet. Therefore, this calls for simple but strict measures aiming at each hazardous step during the use of LPG to prevent these burn injuries.

BACKGROUND: On June 27, 2015, a colored powder explosion occurred in Taiwan. As a result, 499 people were injured, and over 200 people were in critical condition because of severe burns. Forty-nine casualties were transported to the Chang Gung Memorial Hospital. METHODS: We undertook a single-center retrospective observational study using clinical data for 37 patients with major burns with more than 20% total burn surface area (TBSA). We describe the experience of managing patients with acute burn injuries in these patients. Patient-specific data were analyzed and expressed as mean ± standard deviation. RESULTS: Thirty-seven major burn patients were admitted to our hospital. The mean ± SD age was 22.5 ± 5 years. The mean ± SD TBSA was 48.9% ± 20%. All patients were stabilized within 6 hours after admission, and no patient experienced hypothermia or hypovolemia. We performed 95 debridement procedures and 88 skin grafts. A mean of 5.6 surgeries were performed for each patient. The mean ± SD hospital stay was 62 ± 32 days. The ratio for hospital days/%TBSA was 1.36, and hospital charges/hospital days ratio was US $973 a day for surviving patients. Two mortalities (2/37, 5.4%) were reported: one was related to cardiac insult, and another was caused by sepsis. CONCLUSIONS: We share our experience in managing 37 major burn patients in a colored powder explosion to improve the holistic care in modern mass burn casualties. Aggressive early debridement and skin grafting reduced hospital stay and costs.

BACKGROUND: Corrosive ingestion results in necrosis of the digestive tract, spillage of intraluminal fluid, and spread of bacteria that threatens the lives of patients. Some authors advise extensive surgery, although others recommend conservative operation. This study presents the outcomes of the patients of corrosive injury who undergo emergent surgery. METHODS: We conducted a retrospective review including patients with corrosive injury from Jan 2007 to Dec 2013. We retrieved and analyzed the demographic characteristics, injury location and extent, endoscopic grade, presence of surgery, surgical timing and procedure, and mortality. RESULTS: The cohort consisted of 112 patients; 23 of the patients underwent an emergent operation. Patients who needed emergent surgery had the worse endoscopic severity and a higher mortality rate of 47.8% (12/23). Perforation of the digestive tract [odds ratio (OR) 13.5, p = 0.011] and unscheduled reoperation (OR 13.2, p = 0.033) were factors that predict mortality. CONCLUSION: Corrosive injury resulted in a dismal prognosis, especially when patients required an operation. The mortality is related to digestive tract perforation and unscheduled reoperation. Inadequate resection might lead to unscheduled reoperations, which lead to a dismal prognosis.

Endoscopy is generally speculated to be unnecessary in sodium hypochlorite (NaClO) ingestions; however, a significant number of endoscopic evaluations are still being performed when this chemical is ingested. Therefore, the aim of the current study was to compare the outcome and endoscopic findings between patients who had ingested household NaClO and those who had ingested other types of corrosives. This retrospective cohort study enrolled 137 patients with a history of corrosive substance ingestion admitted to a tertiary hospital. Data were extracted from hospital records, and interviews were performed on follow-up. Demographic characteristics, endoscopic findings, and patient outcome were compared between those who had ingested household NaClO and those who ingested other corrosives (NaClO and control cohorts, respectively). Most patients (73%) had attempted suicide. Dysphonia (P ≤ .001), dysphagia (P = .04), and mouth burns (P = .047) were significantly different between the NaClO and control cohorts. Furthermore, patients who had dysphonia, dysphagia, skin burns, drooling, hematemesis, retrosternal pain, and abnormal abdominal examination were prone to death or severe complications. None of the NaClO cohort patients had severe endoscopic complications. All patients in the NaClO cohort survived without any sequelae (Odds Ratio (OR) [95% Confidence Interval (CI)] = 0.87 [0.80-0.94]) while 6 and 5 patients died and developed severe complications in the control cohort, respectively. Studies on endoscopic evaluations in patients who ingested household NaClO are scarce. Our results show that if there are no major clinical manifestations, urgent endoscopic evaluations are unnecessary in such patients.

Caustic substance ingestion (CSI) is a serious medical problem with potentially devastating short- and long-term consequences. Early upper gastrointestinal endoscopy (EaEn) is recommended to evaluate the extent of injury and guide management but there has been controversy about the timing. There is no nationwide study evaluating adherence to EaEn and outcomes following CSI.Nationwide Inpatient Sample database 2003-2011 was used to identify all-age, nonreferral, urgent/emergent admissions with E-International Classification of Diseases Ninth Revision codes for CSI. We evaluated the association of undergoing late endoscopy (LaEn, >48 hours since admission) with poor clinical (death or systemic complications) and economic (cost for admission and length of stay above the 75th percentile) outcomes after controlling for other demographic and clinical factors using a multivariate analysis.We identified 21,682 patients with a median age of 37 years, 51% males, 43% Caucasians, with suicidal ingestion reported in 40%. Endoscopy was performed in 6011 patients (37%). The majority had EaEn (43% within 24, and 40% within 24-48 hours), whereas 17% had LaEn.Compared to EaEn group, the LaEn group was associated with a three-fold increase (OR = 2.7, P < 0.001) in the risk for poor clinical outcome: a fourfold increase (OR = 4.6, P < 0.001) in high cost admissions, and a fivefold increase (OR = 4.9, P < 0.001) in prolonged hospitalization. There was no significant difference in clinical outcomes based on endoscopy within 24, and 24-48 hours of admission.In this retrospective nationwide database analysis, undergoing LaEn was associated with both negative clinical and economic outcomes. More studies are needed to further examine the reasons for delaying endoscopy and subsequent management pathways based on the endoscopic findings. Early endoscopic evaluation could potentially improve the clinical outcomes and reduce costs of these admissions.

BACKGROUND: The optimal clinical management of patients following ingestion of potentially caustic lesions is still undetermined. In particular, the indication for early upper GI endoscopy in this context remains unclear. PURPOSE: To draft recommendations regarding the use of early upper GI endoscopy following hospital admissions of patients after ingestion of potentially caustic agents. METHODS: For this purpose, a retrospective cohort study of patients treated for ingestion of potentially caustic substances during a 13 year-period at the university hospital of Berne was performed. RESULTS: In total, 61 patients with acute ingestion of potentially caustic substances were identified. Overall mortality was 5â%. 11/61 patients had to be admitted to the intensive care unit. Most ingestions were performed in suicidal intention (62â%). In 53â% of these patients, a combined ingestion of several substances occurred. In 33â% of patients, an early upper GI endoscopy was performed within 24 hours after ingestion. The degree of burn depended upon the hazard potential of the respective substance. In patients with ingestion of low risk substances, upper GI endoscopy was only performed when additional risk factors were present. CONCLUSION: Based upon the results of the present study, ingestion of potentially caustic agents requires an individualized strategy whether or not to perform early endoscopy.

BACKGROUND: Endoscopy is the standard of care for emergency patient evaluation after caustic ingestion. However, the inaccuracy of endoscopy in determining the depth of intramural necrosis may lead to inappropriate decision-making with devastating consequences. Our aim was to evaluate the use of computed tomography (CT) for the emergency diagnostic workup of patients with caustic injuries. METHODS: In a prospective study, we used a combined endoscopy-CT decision-making algorithm. The primary outcome was pathology-confirmed digestive necrosis. The respective utility of CT and endoscopy in the decision-making process were compared. Transmural endoscopic necrosis was defined as grade 3b injuries; signs of transmural CT necrosis included absence of postcontrast gastric/ esophageal-wall enhancement, esophageal-wall blurring, and periesophageal-fat blurring. RESULTS: We included 120 patients (59 men, median age 44 years). Emergency surgery was performed in 24 patients (20%) and digestive resection was completed in 16. Three patients (3%) died and 28 patients (23%) experienced complications. Pathology revealed transmural necrosis in 9/11 esophagectomy and 16/16 gastrectomy specimens. Severe oropharyngeal injuries (P = 0.015), increased levels of blood lactate (P = 0.007), alanine aminotransferase (P = 0.027), bilirubin (P = 0.005), and low platelet counts (P > 0.0001) were predictive of digestive necrosis. Decision-making relying on CT alone or on a combined CT-endoscopy algorithm was similar and would have spared 19 unnecessary esophagectomies and 16 explorative laparotomies compared with an endoscopy-alone algorithm. Endoscopy did never rectify a wrong CT decision. CONCLUSIONS: Emergency decision-making after caustic injuries can rely on CT alone.

BACKGROUND: The mechanisms of damage to the gastrointestinal tract after caustic ingestion are conditioned by the nature of the ingested agent. Whether the nature of the ingested agent has a direct influence on patient outcomes is unknown. METHODS: From January 2013 to April 2015, 144 patients underwent emergency management for caustic injuries at the Saint Louis Hospital in Paris. There were 51 men (51 %) and the median age was 44 years [39, 48]. The ingested agents were soda-based strong alkali in 85 patients (59 %), strong acids in 36 patients (25 %), and bleach in 23 patients (16 %). Emergency and long-term outcomes were compared according to the nature of the ingested agent. RESULTS: Four patients died (3 %) and 40 patients (28 %) experienced complications. After bleach ingestion, emergency morbidity and mortality were nil, no patient required esophageal reconstruction, and functional outcome was successful in all patients. Acids were more likely to induce transmural gastric (31 vs. 13 %, p =0.042) and duodenal (9 vs. 0 %, p = 0.04) necrosis than strong alkalis, but rates of transmural esophageal necrosis were similar (14 vs. 12 %, p = 0.98). No significant differences were recorded between emergency mortality (9 vs. 1 %, p = 0.15), morbidity (33 vs. 33 %, p = 0.92), the need for esophageal reconstruction (25 vs. 20 %, p = 0.88), and functional success rates (76 vs. 84 %, p = 0.31) after acid and alkali ingestion, respectively. CONCLUSION: Bleach causes mild gastrointestinal injuries, while the ingestion of strong acids and alkalis may result in severe complications and death. Acids cause more severe damage to the stomach but similar damage to the esophagus when compared to alkalis.

BACKGROUND: Chemical burns occur frequently in western Zhejiang Province. This study documents the epidemiology of chemical burns in the region using burn data from a local specialized hospital. Results from this analysis will assist in the planning of prevention strategies for high-risk occupations and groups. METHODS: A 10-year retrospective analysis was conducted for all patients with chemical burns admitted to the Department of Burn and Plastic Surgery from January 2004 to December 2013. Information obtained for each patient included demographics (gender, age, occupation and education), location of the burn, cause of the burn, and categories of chemicals. Data regarding the season of admittance, prehospital treatment, wound site/size (area, region, and depth), accompanying injuries, operations, length of hospital stay and mortality were also assessed. RESULTS: A total of 690 patients (619 males, 71 females; average age: 30.6±12.4 years) were admitted to the department for chemical burns. Over the 10-year period, the incidence of chemical burns showed an increasing tendency. Chemical burns occurred most frequently in patients aged 20-59 years (94.79%). Most of the chemical burns were work-related, primarily in private enterprises (47.97%) and state-owned enterprises (24.93%). Operations (68.99%) and machine problems (17.26%) were the main causes of chemical burns in the workplace. With regard to burns caused by chemicals, most were caused by acids (72.01%), with hydrofluoric acid and sulphuric acid causing 51.45%. Most chemical burns occurred in the summer and autumn seasons (61.02%). The burn size was <10% of the total body surface area (TBSA) for 445 patients (64.49%), while only 26 patients (3.76%) had burns covering >40% TBSA. The most common burn sites were the upper extremities (31.57%), lower extremities (19.86%), and head and neck (28.83%). Most patients (581 (84.20%)) received water washing treatment on site immediately after exposure. The most common accompanying injuries included inhalation injury, ocular burns and digestive tract injury. The average hospital stay was 17.0±23.1 days (range 1-333 days). Surgery was performed in 146 patients (21.16%), and the overall mortality rate was 0.58%. CONCLUSIONS: Chemical burns are preventable. The high morbidity of chemical burns in western Zhejiang Province is related to the industrial structure of the area. Governmental management in the fields of production, transportation, and utilization of chemicals could be improved. Workplaces have the responsibility to provide safe work environments and equipment, as well as occupational education and safety training for high-risk work groups.

OBJECTIVE: To compare the outcomes of a modified laparoscopic intraluminal stenting with the conventional laparatomic technique in patients with esophageal caustic injuries. METHODS: A total of 103 patients with esophageal burns were included in this retrospective analysis. Patients were candidates for esophageal stenting to prevent future stenosis. According to patient preference, stenting was done with either the innovatory stent with the modified technique (52 patients) or the conventional method that required laparotomy (51 patients). The modified technique consists of placing an inflation balloon stent via laparoscopy. Overall mortality and complications after follow-up period (3 months) were compared between the two groups. RESULTS: Two perioperative mortalities were seen, one in each group. Except one patient in the modified technique, all patients returned to normal intake after 3 months of follow-up. However, five patients of the modified group and three in the conventional group developed esophageal strictures (p > 0.05). Gastric outlet obstruction was observed in three patients of the modified group and one in the conventional group (p > 0.05). DeMeester scores showed that there was no gastro-esophageal reflux in both groups (p > 0.05). CONCLUSION: Our results show that the modified technique can reach the efficacy of the conventional method without requiring laparotomy. Thus, far several studies have demonstrated the advantages of laparoscopy over laparotomy. Thus, and in line with the clinical guidelines of the Society of American Gastrointestinal and Endoscopic Surgeons, we recommend using the presented modified technique in patients with caustic esophageal injuries.

The purpose of this study is to investigate the efficacy of decontamination by immediate surgical debridement in the acute management of chemical burns as compared to conventional dilutional approaches by irrigation or wetting. A retrospective review of the medical records of patients admitted to the Burns Centre of the Prince of Wales Hospital, Hong Kong, between 2001 and 2012, was performed. The time to recovery as reflected by the hospital stay for patients who had received immediate debridement, continuous irrigation, and wet packs was calculated and compared. A total of 99 patients were admitted for chemical burns (3.3% of total admissions). There were three mortalities. Immediate surgical debridement failed to achieve a faster recovery than irrigation or wet packs. Continuous water irrigation was better than wet packs in achieving earlier recovery. Continuous water irrigation remains the most preferred method of decontamination in acute chemical burn management.

BACKGROUND: Esophagectomy is the standard of care for high-grade corrosive esophageal necrosis as assessed endoscopically. However, the inaccuracy of endoscopy in determining the depth of intramural necrosis may lead to unnecessary esophageal resection, with devastating consequences. Our aim was to evaluate the use of computed tomography (CT) for the emergency diagnostic workup of endoscopic high-grade corrosive esophageal necrosis. METHODS: In a before (2000-2007)/after (2007-2012) study of patients with grade 3b endoscopic esophageal necrosis, we compared outcomes after routine emergency esophagectomy versus selection for emergency esophagectomy based on CT evidence of transmural necrosis, defined as at least two of the following: esophageal-wall blurring, periesophageal-fat blurring, and the absence of esophageal-wall enhancement. Survival estimated using the Kaplan-Meier method was the primary outcome. RESULTS: Compared to the routine-esophagectomy group (n = 125), the CT group (n = 72) had better overall survival in the crude analysis (hazard ratio [HR], 0.43; 95 % confidence interval [95 %CI], 0.21-0.85; P = 0.015) and in the analysis matched on gender, age, and ingested agent (HR, 0.36; 95 %CI, 0.16-0.79; P = 0.011). No deaths occurred among patients managed without emergency esophagectomy based on CT findings, and one-third of CT-group patients had their functioning native esophagus at last follow-up. Self-sufficiency for eating and breathing was more common (84 % vs. 65 %; relative risk [RR], 1.27; 95 %CI, 1.04-1.55; P = 0.016) and repeat suicide less common (4 % vs. 15 %; RR, 0.27; 95 %CI, 0.09-0.82; P = 0.019) in the CT group. CONCLUSION: The decision to perform emergency esophagectomy for endoscopic high-grade corrosive esophageal injury should rely on CT findings.

BACKGROUND: Although the outcomes of caustic ingestion differ between children and adults, it is unclear whether such outcomes differ among adults as a function of their age. This retrospective study was performed to ascertain whether the clinical outcomes of caustic ingestion differ significantly between elderly and non-elderly adults. METHODS: Medical records of patients hospitalized for caustic ingestion between June 1999 and July 2009 were reviewed retrospectively. Three hundred eighty nine patients between the ages of 17 and 107 years were divided into two groups: non-elderly (< 65 years) and elderly (≥ 65 years). Mucosal damage was graded using esophagogastroduodenoscopy (EGD). Parameters examined in this study included gender, intent of ingestion, substance ingested, systemic and gastrointestinal complications, psychological and systemic comorbidities, severity of mucosal injury, and time to expiration. RESULTS: The incidence of psychological comorbidities was higher for the non-elderly group. By contrast, the incidence of systemic comorbidities, the grade of severity of mucosal damage, and the incidence of systemic complications were higher for the elderly group. The percentages of ICU admissions and deaths in the ICU were higher and the cumulative survival rate was lower for the elderly group. Elderly subjects, those with systemic complications had the greatest mortality risk due to caustic ingestion. CONCLUSIONS: Caustic ingestion by subjects ≥65 years of age is associated with poorer clinical outcomes as compared to subjects < 65 years of age; elderly subjects with systemic complications have the poorest clinical outcomes. The severity of gastrointestinal tract injury appears to have no impact on the survival of elderly subjects.

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.

STUDY OBJECTIVES: Ingestion of a corrosive substance produces an injury to the gastrointestinal tract and it is often difficult to evaluate the severity and prognosis of this injury. Increased concentrations of plasma nuclear DNA and mitochondrial DNA (mtDNA) have been found to be associated with the area of corrosion. This study examined the level of plasma DNA as it relates to the severity of corrosive injury. METHODS: Forty-eight consecutive patients were enrolled prospectively. The concentrations of plasma nuclear DNA and mtDNA were measured by real-time quantitative polymerase chain reaction assay at presentation to the emergency room and 12 h later. RESULT: The median age of the patients enrolled was 55 years (20 men and 28 women) with an overall mortality rate of 21%. Nineteen patients underwent operative intervention secondary to perforation. Findings included significantly elevated plasma nuclear DNA and mtDNA in the mortality group at presentation and 12 h after injury compared to the survival group. CONCLUSION: The concentrations of plasma nuclear DNA and mtDNA were elevated within 4 h after corrosive injury. The elevated concentrations of plasma nuclear DNA and mtDNA could be useful prognostic markers to correlate with the clinical outcome in corrosive patients.

INTRODUCTION: The enzyme poly(adenosine diphosphate-ribose) polymerase affects the repair of DNA in damaged cells. However, its activation in damaged cells can lead to adenosine triphosphate depletion and death. This study was designed to investigate the efficacy of 3-amino benzamide (3-AB), a poly(adenosine diphosphate-ribose) polymerase inhibitor, on the prevention of esophageal damage and stricture-formation development after esophageal caustic injuries in rat. MATERIALS AND METHODS: Forty-five rats were allocated into 3 groups: sham-operated, untreated, and treated groups. Caustic esophageal burn was created by instilling 15% NaOH to the distal esophagus. The rats were left untreated or treated with 3-AB 10 mg/kg per day intraperitoneally. All rats were killed on the 28th day. Efficacy of the treatment was assessed by measuring the stenosis index and histopathologic damage score and biochemically by determining tissue hydroxyproline content, superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA), and protein carbonyl content (PCC) in esophageal homogenates. RESULTS: Treatment with 3-AB decreased the stenosis index and histopathologic damage score seen in caustic esophageal burn rats. Hydroxyproline level was significantly higher in the untreated group as compared with the group treated with 3-AB. Caustic esophageal burn increased MDA and PCC levels and also decreased SOD and GPx enzyme activities. On the contrary, 3-AB treatment decreased the elevated MDA and PCC levels and also increased the reduced SOD and GPx enzyme activities. CONCLUSION: 3-Amino benzamide has a preventive effect in the development of fibrosis by decreasing tissue damage and increasing the antioxidant enzyme activity in an experimental model of corrosive esophagitis in rats.

BACKGROUND: Corrosive injuries of the upper aero-digestive tract are a frequent cause of morbidity in India. We report here our institution's experience in managing patients with corrosive strictures of the stomach. METHODS: Records of 28 patients who underwent definitive surgery for corrosive strictures of the stomach in our institution over a 15-year period were reviewed. RESULTS: The main presenting complaints were vomiting (75%), dysphagia (46%) and significant weight loss (100%). Pre-operative evaluation included barium and endoscopic studies. Most patients had antro-pyloric strictures (n=22); in 6 patients, however, near-total or total gastric involvement was observed. Thirteen (46%) patients had associated strictures of the esophagus; of these, 7 responded to esophageal dilation. Strictures of the stomach were managed with resectional procedures like distal gastrectomy (n=16), subtotal gastrectomy (1) or total gastrectomy (3) and esophagogastrectomy (1) in 21 (75%) patients. The remaining 7 patients underwent bypass procedures like gastrojejunostomy (5), stricturoplasty (1), and colonic bypass of esophagus and stomach (1). Three patients had entero-cutaneous fistulae in the postoperative period. One patient died in hospital of septicemia and malnutrition. CONCLUSIONS: In patients with corrosive strictures of the stomach, surgery, tailored according to the extent of gastric involvement and presence of associated esophageal strictures, gives excellent results.
