            Notes: Case report of a 17-year-old girl diagnosed with SMAS with a 3-year history of illness. After conservative treatment failed, lysis of the duodenum was performed successfully as of 1 year follow up. Lysis of the distal duodenum does not involve an anastomosis but is differentiated from the Strong’s procedure. Includes surgical procedures.

Journal of Clinical Gastroenterology, 11(4), 386-391. doi:10.1097/00004836-198908000-00007 Notes: An early study following up on 16 SMAS patients treated previously with duodenojejunostomy. Only one had complete remission of symptoms. They found that the long-term results were excellent in three patients, good in six, satisfactory in five, and poor in two. Includes description of diagnostic procedures and emphasizes importance of initial conservative treatment.
