Wilkie’s syndrome, or superior mesenteric artery syndrome (SMAS), is a rare clinical entity caused by compression of the third portion of the duodenum between the abdominal aorta and superior mesenteric artery, leading to duodenal obstruc- tion and severe malnutrition. The authors report a case of a female patient with years of chronic intestinal obstruction with abdominal pain, vomits and weight loss. Contrast intestinal series showed dilation of stomach and duodenum. Abdominal computed tomography study revealed ﬁndings compatible with SMAS. After initial nutritional support, she was successfully treated by laparoscopic duodenojejunostomy. Surgical treatment of SMAS may be necessary in most cases with chronic symptoms or conservative treatment failure. A minimally invasive approach can be considered a safe surgical option with favourable outcomes. Clinical details, diagnostic studies and treatment are discussed. or refractory symptoms [3, 7]. A minimally invasive approach can INTRODUCTION be considered a good approach with favourable outcomes [3, 8]. Wilkie’s syndrome, or superior mesenteric artery syndrome (SMAS), is a rare clinical condition characterized by partial or complete duodenal obstruction [1, 2].

Vomiting was by Wilkie who published the largest series of cases in 1927 [2–4]. The main symptoms of this condition are postprandial usually initiated 3–4 h after meals and consisted of undigested food. She had no signiﬁcant prior medical history.

These ﬁndings were suggestive of an aortomesenteric clamp. Hence, based on known ﬁndings, the diagnosis of Wilkie’s syndrome was established.

[2, 8], is a rare entity deﬁned as a compression of the third por- tion of the duodenum between the SMA and AA leading to par- tial or complete duodenum obstruction [5, 6, 9]. The normal aortomesenteric angle and distance are 25–60° and 10–28 mm, respectively . However, in SMAS this angle is narrowed to <25° and the distance is shortened to < 8mm [7, 10]. Several factors are associated with SMAS, mainly marked weight loss as a consequence of other diseases (cancer, bariatric surgery, chronic infections, severe burns) but may also be congenital such as shorten Treitz’s ligament or abnormal origin of the SMA, or associated with surgical interventions that distorts the anatomy as scoliosis correction or esophagectomy [3, 4, 6].

The diagnosis requires a high degree of suspicion [3, 8]. The low index of suspicious can lead to delays in diagnosis resulting in DISCUSSION a chronic course of symptoms [1, 6]. Several imaging studies SMAS, also known as Wilkie’s syndrome, mesenteric duodenal such as ultrasonography, CT scan, contrast digestive series and compression syndrome, chronic duodenal ileus or cast syndrome endoscopy may be necessary to conﬁrm the diagnosis [2, 3, 8].

Starley in 1910, and it is the current preferred treatment of SMAS with a success rate that reaches 90% [3, 8]. All these proce- dures can be done by a minimally invasive approach although experience is limited . In 1998, Gersin and Heniford ﬁrst described a laparoscopic duodenojejunostomy and this proced- ure spread as a viable surgical alternative, without the risks and morbidity associated with an open surgery . The present case report emphasizes that a minimally invasive surgery may be a relatively easy approach, safe and effective in the deﬁnitive treatment of SMAS.
