Midgut volvulus due to intestinal malrotation is a rare occurrence in adult life. Malrotation is a congenital, developmental anomaly that results from an arrest of the physiological rotation of the gut through 270°. It is often thought that complications due to it, present themselves early during childhood and rarely occur among adults. However, a few cases have occurred and have been reported among adults. When it does occur in adults, it is often associated with catastrophic consequences. We present the case of a 45-year-old man with malrotation resulting in midgut volvulus. Our patient is a 45-year-old man, who presented with sudden onset of colicky abdominal pain and abdominal swelling of 24 h duration. He had been having recurrent abdominal pain since childhood. Physical examination revealed a patient in shock with markedly distended abdomen and anterior abdominal wall edema. Plain abdominal X-ray showed multiple air-fluid levels with thickened bowel outline. A diagnosis of intestinal obstruction was made. The patient was fully resuscitated and planned for emergency exploratory laparotomy under general anesthesia. Intraoperative findings revealed a 360° clockwise rotation of the small bowel around the mesenteric pedicle of the superior mesenteric artery and vein including about 350 cm of bowel gangrene. Resection and anastomosis were done. The early postoperative period was uneventful. However, he had anastomotic dehiscence on the 5th postoperative day and had to be reoperated but sadly he died 24 h later due to complications of anesthesia. Nonspecific recurrent abdominal complaints in adults of any age should raise suspicion of the possibility of a midgut malrotation or malfixation with or without intermittent volvulus. This case highlights the importance of early diagnosis and treatment.

| Introduction|| |
Midgut malrotation is generally regarded as a pediatric pathology with the majority of patients presenting in childhood.,, The incidence has been considered to be approximately 1 in 500 live births. It is believed that more than 90% of patients will present by the time of their first birthday, with a majority of the complications occurring in the 1st month of life., Therefore, diagnosis is rare in adults with a reported incidence of 0.2%–0.5%,,, which sometimes leads to delay in seeking healthcare and treatment.
Most adult diagnoses of midgut malrotation are made among asymptomatic patients; either on imaging investigations for unrelated conditions or at operations for other pathology.
There is, however, a significant proportion of adults that have been affected who may present with acute or chronic symptoms of intestinal obstruction or intermittent and recurrent abdominal pain.
We present the case of a 45-year-old man with midgut volvulus and bowel gangrene resulting from malrotation.
| Case Report|| |
Our patient is a 45-year-old man, who presented with sudden onset of colicky abdominal pain and abdominal swelling of 24 h duration. He had been having recurrent abdominal pain since childhood.
Physical examination revealed a patient in shock with markedly distended abdomen and anterior abdominal wall edema. Plain, erect abdominal X-ray film showed multiple air fluid levels while the supine film showed dilated loops of bowel [Figure 1].

He was fully resuscitated and worked up for surgery. He had an emergency exploratory laparotomy under general anesthesia. Intraoperative findings revealed a 360° clockwise rotation of the small bowel around the mesenteric pedicle of the superior mesenteric artery and vein complicated by bowel gangrene of about 350 cm [Figure 2]. Resection and end to end jejunoileal anastomosis was done, with only about 130 cm of proximal small bowel left and 4 cm of terminal ileum. The immediate postoperative period was uneventful. However, he had anastomotic dehiscence on the 5th postoperative day and had to be reoperated intraoperative findings were that of anastomotic leak with marked dilated and thickened small bowel loops proximal to the anastomotic line and a collapsed distal bowel. A jejunostomy was done. The patient did not fully recover from anesthesia and sadly, died 24 h later.
| Discussion and Review of Literature|| |
Midgut malrotation is rare in adults. The index patient is the first adult case of midgut malrotation with volvulus in our practice. This is consistent with the reported low incidence of malrotation in adults which is approximately 0.2%–0.5%.,,
This patient presented with features of acute intestinal obstruction, he, however, reported the previous history of abdominal symptoms from childhood. Clinical presentation of rotational abnormality of the gut in adults is usually different to that of pediatric patients. Two distinct patterns of adult presentations have been reported: Acute and chronic. The chronic presentation is more common in adults. This is characterized by intermittent crampy abdominal pain, bloating, nausea and vomiting over several months or years.,,,
However, the patient may present for the first time acutely and may report a previous history of abdominal symptoms, as in the case of our patient. A high index of suspicion is therefore needed.
Abdominal X-ray done for our patient showed features of intestinal obstruction, however, preoperative diagnosis was not made in the patient because plain X-ray has low diagnostic yield.
Other means of diagnosis of midgut malrotation include upper gastrointestinal (UGI) contrast study, Doppler ultrasound scan, computed tomography (CT) scan, magnetic resonance imaging scan, and mesenteric arteriography.,, These were not done in our patient because of his acute presentation and financial constraints.
The reported gold standard for diagnosis of gut malrotation is a UGI contrast study, particularly in the pediatric age group.,,,, This will generally show the duodenum and duodenojejunal flexure located to the right of the spine.
CT scan with or without UGI contrast study is increasingly used preferentially as it is now considered the investigation of choice; providing diagnostic accuracy of 80%.,,,
Symptomatic midgut malrotation undoubtedly requires surgical intervention although the management of asymptomatic patients is more controversial.,
Our patient had volvulus with bowel gangrene necessitating bowel resection and anastomosis, however, the standard operation for malrotation is Ladd's procedure., The patient sadly did not survive long enough for us to determine if he will have had further symptoms since we did not do the standard procedure.
| Conclusion|| |
Midgut volvulus due to malrotation could occur in adults. It is often associated with a diagnostic dilemma and poor prognosis. A high index of suspicion is therefore required in patients of any age group with abdominal symptoms.
