Annular Pancreas

Sonography of Pancreatic Ductal Anatomic Characteristics in Annular Pancreas

“…An early appearance usually occurs within the first few days of life and appears to be associated with duodenal stenosis or atresia in more than 40% of cases. 3 It is frequently associated with other congenital abnormalities, such as esophageal atresia, imperforate anus, congenital heart disease, malrotation of the midgut, and Down syndrome. There are 2 embryologic hypotheses for annular pancreas.…”

Pneumoperitoneum in the Management of Abdominal Incisional Hernia

“…A number of authors have proposed that pneumoperitoneum should continue for longer periods; in some cases even for months (Mason, 1956;Whelan and Eaker, 1962;Ravitch, 1963;Martin, 1966). A fine polythene catheter put into the abdominal cavity has been used for repeated insufflations of air over an extended time, so avoiding multiple paracenteses (Steichen, 1965).…”

“…This simple adjuvant has been used to assist the repair of other types of hernia: inguinal (Mensuy and Hager, 1958;Moore, Conn, and Guida, 1968; CLINICAL EXPERIENCE Ten patients with incisional hernia (Table I ) Pingree and Clark, 1968) and omphaloceles (Spratt, 1961;Whelan and Eaker, 1962;Ravitch, 1963;Nissan, 1965;Steichen, 1965). Using this method it is possible to enlarge the abdominal cavity sufficiently to permit a sound repair without resort to artificial implants, or attempts to reduce the normal abdominal contents by resection of bowel or omentum.…”

Annular pancreas and jaundice

“…Division of the annulus was to be avoided as that procedure is associated with a high morbidityrate. Whelan and Hamilton (1957), who collected 21 records in which the annulus had been divided, found that in 1 1 the operation was complicated by fistula formation, pancreatitis, or failure to relieve the obstruction. Brown, Bingham, and Cronk (1948) divided the annulus in order to inspect the papilla in a jaundiced patient; the patient died with a fistula and a subphrenic abscess.…”
