Robotic modified Strong procedure for superior mesenteric artery syndrome

A Delayed Presentation of Superior Mesenteric Artery Syndrome Treated With Robotic-Assisted Strong Procedure

Superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, is a rare condition resulting from compression of the third portion of the duodenum between the aorta and the superior mesenteric artery. When symptomatic, this compression may result in nausea, vomiting, epigastric discomfort, and weight loss, requiring clinical attention and imaging to make the diagnosis. Typically, SMA syndrome presents in young females and is associated with an underlying condition such as anorexia nervosa, cachexia, postoperative development after scoliosis surgery, etc. In this report, we present the case of an atypical delayed presentation of SMA syndrome in an 84-year-old male who had epigastric pain, nausea, intermittent vomiting, and a 30-pound weight loss over two years. SMA syndrome was diagnosed on a computed tomography (CT) scan by a decreased angle between the superior mesenteric artery and abdominal aorta, and treatment with a robotic-assisted strong procedure was performed. The patient was followed postoperatively in the clinic and tolerated the procedure well.

Delayed presentation of Wilkie's syndrome after scoliotic curve correction surgery: a case report

BACKGROUND

Superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, is a rare but serious complication following scoliosis correction surgery. It occurs as a result of mechanical compression of third part of duodenum between the SMA and aorta. This condition occurs most commonly in significantly underweight patients with deformities, and usually during the first week following spinal deformity corrective surgeries. The angle between the abdominal aorta and the SMA gets reduced following spinal lengthening during deformity correction surgery causing compression of third part of duodenum resulting in development of SMA syndrome.

CASE PRESENTATION

We present a case of 17-year-old male with congenital scoliosis with a 70-degree scoliotic curve who underwent spinal deformity correction surgery with posterior instrumented fusion. Post-operative course was uneventful and the patient was discharged after suture removal on post-operative day 15. The patient presented after 21-days of symptom onset on post-operative-day 51, with a 3 week history of post-prandial vomiting, abdominal pain and distension which resulted in rapid weight loss of 11 kg. A CT-angiogram showed obstruction at third part of duodenum. After reviewing clinical and radiological profile of the patient, a diagnosis of SMA syndrome was made. Conservative management was tried, but due to rapid deterioration of patient condition and symptoms of complete intestinal obstruction, the patient was treated surgically by gastro-jejunostomy and side-to-side jejuno-jejunostomy, which improved his condition.

CONCLUSION

SMA syndrome can occur much later than previously reported cases and with potentially life-threatening symptoms following scoliosis correction. Having a high index of suspicion, early recognition of condition and institution of appropriate treatment are essential to prevent occurrence of severe complications including risk of intestinal perforation and mortality. This case highlights management of delayed onset of SMA syndrome, with presentation further delayed after symptom onset, as is common in developing parts of the world, due to limited availability and accessibility of resources, and low socio-economic status of large segments of the population.

Robotic management of superior mesenteric artery syndrome

Wilkie's syndrome is an unusual cause of upper intestinal obstruction due to mechanical compression of the superior mesenteric artery (SMA) to the duodenum, with nonspecific symptoms, whose diagnosis is confirmed by angiotomography. Initially, the treatment is conservative to regain weight and restore mesenteric adipose tissue, associated with postural changes of the patient. If this fails, surgical treatment is indicated, being laparoscopic duodenojejunostomy described as the gold standard. Robotics' assistance is feasible and safe to carry out the procedure. We present the case of a 21-year-old male patient who comes with stabbing abdominal pain and persistent postprandial vomiting that has caused weight loss of 11 kilograms in the last 2 years without apparent cause, associated with gastroesophageal reflux. During the procedure, we evidenced open diaphragmatic pillars and duodenal compression due to SMA, and robotic-assisted laparoscopic hyatoplasty + Nissen fundoplication + duodenojejunostomy were performed without complications, with excellent post-surgical results.
