Is acute appendicitis different in patients with sickle cell disease?

Nine patients with sickle cell disease (SCD) were operated upon at our hospital for acute appendicitis, comprising only 0.43% of the total appendicectomies performed at our institution. Three appendices were acutely inflamed and six (66.7%) were perforated. Histologic evaluation of the six perforated specimens revealed congestion and haemorrhage by sickled erythrocytes (RBCs) in addition to acute transmural inflammatory cell infiltrates. The mucosa was extensively ulcerated, with haemorrhage both within the lumen and in the appendiceal wall. The blood vessels were dilated and packed with sickled RBCs. Two of the three acutely inflamed appendices showed features of acute transmural appendicitis, with marked congestion and haemorrhage by sickled RBCs. The third did not show any acute inflammatory cell infiltrate, however, the mucosa was partly ulcerated with both mucosal and intraluminal haemorrhage. These findings suggest that acute appendicitis is different in patients with SCD: while it is not common, when it does develop it has a rapid course with a high incidence of perforation due to blockage of appendiceal vessels by sickled RBCs, leading to transmural necrosis.

Laparoscopic versus open cholecystectomy in children.

Twenty-one consecutive laparoscopic cholecystectomies (LC) were compared with 29 consecutive open cholecystectomies (OC). Sickle-cell disease (SCD) was the most common reason for cholecystectomy in both groups. The average length of operative time for LC was significantly longer than that of OC (P=0.0149). In 1 patient there was conversion from LC to OC due to severe adhesions. Common bile duct (CBD) stones were diagnosed in 8 (27.6%) of the OC group; in 4 of them the diagnosis was made preoperatively by ultrasound, in 4 by intraoperative cholangiogram. All 8 patients required CBD exploration, and 2 had additional transduodenal sphincteroplasties. In the LC group 5 patients (23.8%) had CBD stones. All had (ERCP) endoscopic retrograde cholangiopancreatography sphincterotomy, and stone extraction followed by LC. ERCP is a necessary adjunct to treatment if LC is to be contemplated. Six patients in the OC group developed complications, while only 4 patients in the LC group developed minor complications. The length of hospitalization after LC was significantly shorter than after OC (P=0.0150). LC is the procedure of choice in the management of cholelithiasis in children, especially those with SCD.

Concurrent left congenital diaphragmatic hernia and esophageal atresia: case report and review of the literature.

Coexisting congenital diaphragmatic hernia and esophageal atresia is an extremely rare phenomenon. Details of one infant with such a combination is presented, and the literature on the subject is reviewed.

Acute intestinal obstruction.

Nine hundred and four children with intestinal obstruction were studied. Necrotising enteritis was the commonest cause of intestinal obstruction in children. Acute intussusception was the second commonest cause in the whole group and the commonest cause in children under 1 year of age. Less common causes included band obstruction, sub acute intestinal obstruction and remnants of vitello-intestinal duct. A steady and significant improvement in the results of treatment was noted in children suffering from necrotising enteritis in the study period.
