Duodenal Obstruction*

Intestinal malrotation occurs because of an arrest of normal rotation of the embryonic gut. It is often diagnosed in first month of life because of acute complications and requires surgical management. If it is not detected at a young age, it is diagnosed incidentally in advanced age. It is very rarely reported at advanced age with symptoms. In Korea in the last 30 years only about 10 such cases have been reported. In 2010, intestinal malrotation was reported at advanced age in only one case who had acute duodenal obstruction due to non-rotation of the pre-arterial segment of mid-gut. Therefore, we report a case of a 45-year-old man with non-rotation of pre-arterial segment with duodenal obstruction who had complained chronic and mild epigastric discomfort from a year ago.

Superior mesenteric artery (SMA) syndrome is a rare disorder, characterized by a decreased aortomesenteric angle that causes a duodenal obstruction. Various medical and psychiatric conditions may result in the initial rapid weight loss that causes narrowing of the aortomesenteric angle. Isolated dissection of the superior mesenteric artery (DSMA) is an uncommon cause of acute mesenteric ischemia. Several literature reports suggest that medical treatment in combination with close observation is reasonable in uncomplicated dissection with stable hemodynamic status. Recently, as several reports describe, rapid revascularization by percutaneous angioplasty and endovascular stent insertion can prevent bowel ischemia that progresses to irreversible bowel necrosis. However, the stability of endovascular stents at the DSMA has not been confirmed, because its use is reasonably infrequent. Here, we report a case of SMA syndrome, as a complication of endovascular stent placement at the DSMA.

The most common cause of small bowel obstruction is postoperative adhesion, and besides a hernia, metastatic or primary cancer and small bowel tumors are possible causes. Superior mesenteric artery (SMA) syndrome is a rare cause of upper gastrointestinal obstruction and is associated with debilitating conditions with marked weight loss. SMA syndrome results from the compression of the third part of the duodenum due to the narrowing of the aortomesenteric angle. We report a 28-year-old woman with SMA syndrome after acute gastroenteritis. Her stomach was severely dilated due to the duodenal obstruction and computed tomography showed the compression of the third portion of the duodenum by SMA. She was conservatively cared for and thus favorably improved.

Superior mesenteric artery (SMA) syndrome is an uncommon cause of duodenal outlet obstruction. Symptoms and signs suggestive of this condition are nonspecific, and a high index of suspicion coupled with appropriate imaging studies are necessary for diagnosis. We present the case of a 70-year-old man who developed SMA syndrome following prolonged hospitalisation for a surgically treated bleeding duodenal ulcer. His SMA syndrome resolved after successful nonoperative management based on accepted guidelines for nutritional therapy, thus avoiding the need for reoperation and its attendant risks in a malnourished patient.

Superior mesenteric artery (SMA) syndrome is a rare condition that must be differentiated from other gastrointestinal diseases manifesting as upper abdominal pain, nausea, or vomiting. The description of SMA syndrome is compression of the third portion of the duodenum by the SMA and the abdominal aorta. SMA syndrome is managed with nasoenteral nutrition or surgical strategies such as laparoscopic duodenojejunostomy. However, SMA syndrome treated using enteral nutrition by percutaneous radiologic gastrojejunostomy has not been reported. Here, we report our experience of successfully managing a case of SMA syndrome with percutaneous radiologic gastrojejunostomy.

PURPOSE: Superior mesenteric artery (SMA) syndrome is a rare disorder, characterized by a decreased aortomesenteric angle that causes a duodenal obstruction. It usually occurs after a period of weight loss, nausea or vomiting due to a partial obstruction of the third portion of the duodenum. If conservative management fails, then a laparotomy, with a duodenojejunostomy, is indicated. A minimally invasive laparoscopic approach to the retroperitoneum, or duodenal, operation has recently been introduced. Although the role of laparoscopy in the management of SMA syndrome is not clearly defined, a laparoscopic duodenojejunostomy may be an alternative approach for its surgical treatment. METHODS: We retrospectively reviewed and analysed our experience of 8 cases of SMA syndrome, and included another 45 cases that had previously been reported in the Korean literature since 1967. RESULTS: There was no gender predominance, but SMA syndrome was more common in younger patients. There were several diseases, or underlying conditions, associated with gastrointestinal, or other general conditions, in SMA syndrome. With respect to its surgical management, most cases in Korea were treated with a duodenojejunostomy. We recently experienced two cases of superior mesenteric artery syndrome, which were treated laparoscopically. The operation time and lenghth of hospital stay were acceptable, with no complications. CONCLUSION: SMA syndrome shows a greater predominance in young age, and is associated with many other diseases, or conditions, in Korea. A duodenojejunostomy is the best choice of operative procedure for the treatment of SMA syndrome. A laparoscopic duodenojejunostomy is also a feasible, alternative option in the treatment of SMA syndrome, providing the benefits of a definitive and minimally invasive surgical technique for a duodenal obstruction.

Gallstone ileus is a well-known complication of cholelithiasis, but is relatively rare. Most ectopic gallstones are located in the small bowel; they are rarely found in the stomach and duodenum. We describe the imaging findings of a case of intragastric gallstone, as well as a case in which duodenal obstruction was caused by a large gallstone (Bouveret's syndrome).

Neurofibroma is a benign tumor characterized by diffuse proliferation of the peripheral nerve elements. It mostly occurrs in the retroperitoneal region. Although neurofibroma may occurr as a solitary lesion, its common manifestation is in the syndrome of neurofibromatosis with a variable clinical course. Neurofibroma is a slowly growing neoplasm that presents symptoms only after a period of several years. Complete surgical removal is the treatment of choice, however this can be occasionally dangerous because of their tendency to adhere to adjacent structures. Herein we report a case of neurofibroma causing duodenal obstruction.

Superior mesenteric artery (SMA) syndrome is a rare disease in which the third portion of the duodenum is compressed by SMA. There are many causes leading to the SMA syndrome, however it's extremely rare that aortic aneurysm causes a SMA syndrome. We report a case of a successfully treated SMA syndrome due to an abdominal aortic aneurysm in a renal transplant recipient. The patient was a 52-yr-old woman with a thin stature (weight 40 kg, height 164 cm). She received a renal transplant 8 yr before, and had hypertension and abdominal aortic aneurysm. Her SMA syndrome developed in a prolonged supine position for the accidental rib fractures and was diagnosed by clinical and radiological findings. After a surgical correction (resection of an aneurysm and aortobiiliac bypass with an inverted Y graft), her symptoms relieved without deterioration of the graft function.
