Introduction and importance Midgut Malrotation (MM) is a potentially fatal and rare congenital anomaly that results from an incomplete rotation of the bowel 270 degrees around the Superior Mesenteric Axis. Newborns are the most affected age group, nevertheless, adult malrotation can manifest, but in a much rarer incidence rate. Clinical awareness must be present when faced with a surgical abdomen in an adolescent patient because this pathology can have several misleading signs and symptoms which may eclipse the true preoperative diagnosis and masquerade as another, and this could result in implementing a different therapeutic approach. Swift clinical informed judgments must be made and acted upon to limit the morbidity and mortality resultant from this pathology. Case presentation We present the case of a 15-year-old female, who was brought to our Emergency Department (ED) with a 5-day-history of biliary emesis which evolved into obstipation with continuous and excruciating abdominal pain. Computed Tomography (CT) scan indicated gastric and duodenal dilation in addition to a “Whirlpool sign”. Exploratory laparotomy was done, and a Ladd's procedure was performed. Clinical discussion We treated our patient by performing Ladd's procedure and adhesiolysis. Diagnosis is conventionally established pre-/intraoperatively based on radiological imaging and clinical suspicion. Therapeutic methods for this pathology are primarily surgical in nature. Conclusion Midgut Malrotation is a rare entity, thus, it is crucial to further study this type of clinical presentation and keep it in mind to be able to make an accurate diagnosis to reach the optimal outcome for patients who present with acute surgical abdomen., Highlights • MM is a potentially fatal and rare congenital anomaly of the Gastrointestinal tract comprising 0.2% of live births. • Most cases are diagnosed within the first year of neonatal life. Rarely, a case is diagnosed in the adolescent population. • Symptoms are non-specific and this warrants high clinical suspicion when presented with a case of acute surgical abdomen. • There are three major types of Midgut Malrotation according to the established Stringer classification. • Surgery is the mainstream treatment modality and Ladd's procedure and remains the gold standard for treatment of MM.

Highlights • Original study. • Based on an interesting variation in location of perforated peptic ulcers observed in soldiers posted to high altitude areas. • Literature review and research suggestive of possibility of high altitude induced patho-physiological changes behind gastric perforations. • This study is probably first of it’s kind and may be pioneering for encouraging further studies to establish a definite role of high altitude in causing gastric perforations., Introduction This is an original case series on soldiers evacuated from HAA(High Altitude Area) over last one year(Sept 2017–Aug 2018), of which 100% cases were found to have gastric antrum perforation. This is a deviation from the usual trend that is being noted in Indian subcontinent where duodenal perforations are commonest. Discussion High altitude associated dyspepsia is a common phenomenon and some studies done in high altitude population have recorded high incidence of antral gastritis and mucosal atrophy on histo-pathological evaluation. This is also supported by high incidence of H. pylori infection. The presence of atrophic gastric mucosa associated with antral gastritis, when exposed to hypobaric hypoxemic conditions faced by soldiers posted to heights above 15,000 ft, may leads to increased intra-luminal pressure and ischemia which probably predisposes individuals for gastric antrum perforations. Conclusion This is a relatively untouched topic as we have not found studies onhigh altitude related gastric perforations and probably this is the first case series of its kind. The acknowledgement of this phenomenon may pave way for further studies for defining the role of high altitude in gastric perforations.
