In a 12-year period, 37 of 3,536 burn patients developed acute obstruction of the duodenum by the superior mesenteric artery. Nasogastric decompression and intravenous fluids were required initially in all 37 patients. Twelve patients received no further therapy, with resolution of the obstruction in six and death of the other six from burn wound sepsis or pneumonia. Ten patients underwent operative treatment consisting of either duodenojejunostomy (eight) or vagotomy and gastroenterostomy (two), with resolution in seven and three postoperative deaths. Fifteen patients were treated with intravenous hyperalimentation and gastric decompression, with resolution in 12 patients, one required operative intervention, and two died of complications. A high degree of suspicion followed by prompt diagnosis and treatment of the SMA syndrome are required in all critically ill patients with unexplained bilious vomiting. Gastric decompression coupled with aggressive use of intravenous hyperalimentation recently has reduced the need for operative treatment (42% versus 11%).

In a feeding trial 66 infants of low birth weight received continuous intragastric milk feeds from the fourth hour of life, starting with 60 ml/kg/24 hr and reaching a maximum of 300 ml/kg/24 hr on the ninth day. Each infant received only full-strength milk, which was either expressed human breast milk or SMA-S26 (a proprietary low-protein adapted cows' milk) or half-cream Regal milk (partly-skimmed evaporated cows' milk). For various reasons 10 babies had to be withdrawn, and the final assessment was made on the 56 who completed the trial successfully.Persistent vomiting was a problem in only four infants. In two of them the trial was continued after gastric lavage and in the other two vomiting stopped when the volume was reduced. Despite a careful search no evidence was found of aspiration of feeds in any infant. Continuous intragastric milk infusion was shown to be a safe method of feeding infants of low birth weight and SMA-S26 was almost as well tolerated as human milk. Because of the high-protein content of half-cream cows' milk preparations and the resultant high plasma amino-acid levels when they are given in these large volumes they should be avoided for this type of feeding although they produce better weight gains in the first week of life.

A 6-month-old girl was admitted to another hospital because of consciousness disturbance, preceded by 2 weeks of decreased activity and vomiting. She was referred to our hospital after ventricular drainage had been instituted for hydrocephalus and the tumor in the pineal region. The patient was noted to have conjugate upward gaze palsy and papilledema. CT scan and MRI revealed a large tumor in the pineal region with tumoral hemorrhage and a small mass in the right frontal lobe. At surgery, the pineal region tumor was removed subtotally. Histological examination showed the tumor to be composed of sheets of large polyhedra or round cells with an eccentric round nuclei, prominent nucleoli, and cytoplasmic inclusions. Immunohistochemical studies were positive for GFAP, vimentin, S-100, CK, EMA, and SMA, but negative for AFP, HCG, PLAP, and CEA. Following surgery, she received three 5-day cycles of chemotherapy, consisting of intravenous administration of cisplatin 20 mg/m2/day and etoposide 60mg/m2/day. After these therapies, MRI showed a decrease in the area of high intensity in the pineal region, but almost no change in the right frontal mass lesion. Follow-up radiological examination showed that the tumor had grown rapidly one month after chemotherapy and the patient died 5 months after her first hospitalization. Malignant rhabdoid tumor of the CNS is rare and remarkably malignant. This tumor should be treated using multidisciplinary management with surgery, intensive chemotherapy, and radiotherapy depending on the patient's age.

Plexiform schwannoma is a benign peripheral nerve sheath tumor composed exclusively of schwann cells arranged in a plexiform pattern. Most plexiform schwannomas are skin tumors and there has been only one case report of this tumor originating in the colon. We describe herein the first known case of plexiform schwannoma of the small intestine occurring without any relationship to schwannomatosis or neurofibromatosis. A 57-year-old man presented with a short history of abdominal pain, vomiting, and bloody stool after each meal. Jejunography demonstrated multiple nodular tumors in the small intestine. We resected the small intestine laparoscopically. The tumors consisted of multiple white nodules in the submucosal and subserosal layers. Microscopic examination revealed that each tumor was composed mainly of Antony A tissue, compatible with conventional schwannoma. Immunohistochemically, the tumors were positive for S-100, vimentin, and neuron-specific enolase, and negative for HHF35, Alpha-SMA, and c-kit. No evidence of recurrence has been found in 38 months of follow-up.

Superior Mesenteric Artery Syndrome is an atypical cause of high intestinal obstruction seen frequently in patients with rapid weight loss or immobilization in a body cast (\also called CAST Syndrome). The SMA impinges on the third part of the duodenum immediately after originating from the anterior aspect of aorta, making an abnormally narrow angle with the later. Intestinal obstruction results causing characteristic symptoms like postprandial epigastric pain, eructations, fullness and vomiting. Here we report such a case of SMA syndrome in a patient with history of rapid loss of weight.

Midgut volvulus presenting outside the neonatal period often manifests with less than classic findings. One must be ever vigilant for any deviation from normal when imaging the gastrointestinal tract in these patients. Plain films often are noncontributory, and gastrointestinal imaging findings frequently are subtle and not exactly the same as those seen in classic cases in the neonatal period. Cases are presented illustrating the following: abnormal but less than classic small bowel location and configuration, malabsorption and fortuitous spiraling of a nasogastric tube, viral gastroenteritis and pseudo intussusception, intractable vomiting and dehydration with abnormal cecal position, and duodenal obstruction: pseudo SMA syndrome. Fortunately, one now can confirm one's suspicions with computed tomography and ultrasound in terms of determining whether the superior mesenteric artery and superior mesenteric vein positions are normal or reversed.

We report 3 cases of superior mesenteric artery syndrome in patients previously on maintenance peritoneal dialysis converted to hemodialysis after peritoneal failure. All 3 patients presented with repeated vomiting and severe malnutrition. It is postulated that complications arising from peritoneal dialysis such as peritoneal sclerosis, adhesions and collections after CAPD peritonitis may be important contributing factors for the SMA syndrome in these 3 patients. All of them succumbed within six months of diagnosis. The first 2 patients received gastrointestinal bypass surgery and died post-operatively due to impaired wound healing and nosocomial sepsis. The 3rd patient was treated conservatively with nasoduodenal feeding but succumbed to aspiration pneumonia. It is postulated that complications arising from peritoneal dialysis including peritoneal sclerosis, adhesions and collections after CAPD peritonitis may contribute to the SMA syndrome in these patients. Our experience suggests that SMA syndrome in end-stage renal disease patients is associated with high surgical morbidity and mortality possibly related to their poor pre-morbid condition and pre-existing malnutrition. Aggressive parenteral nutrition should be considered to build up the general status before proceeding to surgical intervention.

Superior mesenteric artery syndrome (SMAS) is an uncommon cause of high intestinal obstruction in neonates; it is owing to incomplete obstruction in the third part of the duodenum caused by compression between the SMA and abdominal aorta. In neonates, complete intestinal obstruction owing to SMAS has been very rarely reported in the literature .We present a 7-day-old previously healthy male infant with a short history of gastroenteritis and sepsis followed by progressive abdominal distension and persistent bilious vomiting that resulted in hypovolemic shock. The patient was aggressively resuscitated, and a gastrografin study showed a hugely distended stomach with an abrupt narrowing at the third part of the duodenum. Exploratory laparotomy unexpectedly revealed a high insertion of the duodenum at the ligament of Treitz, with upward displacement and SMA compression leading to duodenal obstruction. The ligament of Treitz was divided, and the duodenum, mobilized. The postoperative course was uneventful. Although extremely rare, SMAS should be considered as one of the differential diagnoses in newborns presenting with complete intestinal obstruction, especially if preceded by gastroenteritis or sepsis-like symptoms.

Celiac artery compression syndrome (CACS) or median arcuate ligament (MAL) syndrome is a rare vascular disease. The clinical manifestations of CACS include the triad of postprandial pain, vomiting, and weight loss. The pathogenesis of CACS is the external compression of celiac artery by the MAL or celiac ganglion. Moreover, some authors also reported the compression with different etiologies, such as neoplasms of pancreatic head, adjacent duodenal carcinoma, vascular aneurysms, aortic dissection, or sarcoidosis. In the literature, most cases of CACS were reported from Western countries. In contrast, this disease was seldom reported in Oriental countries or regions, including Taiwan. Superior mesenteric artery syndrome (SMAS) is also a rare disease characterized by compression of the third portion of the duodenum by the SMA. The clinical features of SMAS are postprandial pain, vomiting, and weight loss. To date, there are no guidelines to ensure the proper treatment of patients with CACS because of its low incidence. Thus, tailored therapy for patients with CACS remains a challenge as well as the prediction of clinical response and prognosis. The aim of our present study was to investigate the clinical features, the association with SMAS, treatments, and outcomes of patients with CACS in a single institution in Taiwan.

We report the case of a 14-year-old boy with pectus excavatum and mild scoliosis. The patient underwent a minimally invasive Nuss repair with excellent cosmetic result. He returned 3 weeks post-operatively with bilious emesis and a 3.6-kg weight loss (5.5% of total body weight). Radiographic evaluation was consistent with the diagnosis of superior mesenteric artery syndrome and the child ultimately required nasojejunal feedings. Following return to his baseline weight, he was transitioned to oral feedings and has done well in follow-up. This is the first report of SMA syndrome following minimally invasive pectus excavatum repair.
