quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "Fusiform choledochal cyst is usually associated with complicated PBMU as well as debris and/or protein plugs in the common channel. Pancreatic duct anomalies are also often present. IE should be performed up to the distal common bile duct in fusiform cases to confirm that dissection can be performed safely."

quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "In cystic choledochal cyst, the distal common hepatic duct is narrow—sometimes so narrow that it looks blind-ended and cannot be identified specifically. Thus, if mucosectomy is completed up to the pancreatico-biliary junction, it is unlikely that a residual cyst will develop within the pancreas (Fig. 42.5). In contrast, in fusiform choledochal cyst, excision of the distal common hepatic duct is more difficult because the distal common bile duct is still wide at the pancreatico-biliary junction; if it is not excised properly, the likelihood that the distal common bile duct will be left within the pancreas is high."

quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "Surgical problems with cystic choledochal cyst are most often encountered on the proximal side of the pathology, occurring as a result of anatomic variants of the common hepatic duct, uncertainty in relation to the excision level of the common hepatic duct, dilated IHBD, and debris and/or stenosis in the IHBD. In contrast, surgical problems with fusiform choledochal cyst most often arise on the distal side of the malformation and are due to uncertainty in relation to the excision level of the distal choledochus, debris in the common channel, and complicated PBMU." Quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "In comparison with fusiform choledochal cysts, there are usually more adhesions between a cystic choledochal cyst and surrounding vital structures such as the portal vein and hepatic artery, especially in older children. In adolescents and adults, the adhesions are often very dense, and great care is required during cyst excision."

Quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "Nonsurgical reduction has a longstanding history; it was first described by McDermott in 1994. In principle, an enema pushes back the intussuscepted bowel. The progress of the reduction can be monitored by fluoroscopy or ultrasound. As contrast media, air or water-soluble iodine solutions can be used for fluoroscopy, and physiologic saline, for ultrasound. A success rate of up to 95% has been reported for nonsurgical reduction, so this procedure should be considered as a first-line treatment."

quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "Between 25% and 40% of children with ulcerative colitis undergo surgical treatment. As most patients today can be stabilised by medical treatment, emergency operations for toxic megacolon, unremitting bleeding, or refractory fulminant colitis are not common. The typical indications for surgery of ulcerative colitis are poor response to optimal medical treatment, dependence on high-dose corticosteroids with significant side effects, delay in growth and maturation, and severe extraintestinal manifestations of the disease. Surgery should not be considered as a primary or early treatment of ulcerative colitis. A significant proportion of patients achieve long-term symptom relief with conservative treatment and may remain in remission with minimal or no medication. Moreover, the functional outcome following restorative proctocolectomy is not comparable to normal bowel function. When patients go through several exacerbation phases of the disease, they gradually learn to accept that their bowel will function from a few t0imes to several times a day. Before proctocolectomy is undertaken, Crohn’s disease should be ruled out with every possible measure, as Crohn’s disease patients should not undergo restorative proctocolectomy." Quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "The gold standard of surgery for ulcerative colitis has been proctocolectomy and permanent ileostomy. Limited colonic resections, as well as colectomy and ileorectal anastomosis, have been abandoned, as these procedures have been associated with a high incidence of complications and recurrence of the disease. Proctocolectomy and permanent ileostomy gives excellent control of ulcerative colitis and related symptoms, but it is not very well tolerated by children and adolescents because of the significant social restrictions and permanently altered body image that are related to this operation. Since late 1970s, restorative proctocolectomy with ileoanal anastomosis has gained overall acceptance as the standard operative procedure for both adult and paediatric ulcerative colitis. Many paediatric surgeons advocate the use of an ileal reservoir; the most popular and easiest to construct is the J-pouch. Some paediatric surgeons still use a straight ileoanal anastomosis without a reservoir. A two-stage operation (colectomy and pouch formation with ileostomy in the first stage and stoma closure in the second stage) is the most common elective approach for ulcerative colitis. A three-stage operation (first colectomy, then pouch formation, and finally stoma closure) should be considered in patients with high-dose steroid use or severe malnutrition, and when Crohn’s disease has not been completely excluded. Restorative proctocolectomy without ileostomy may be considered in patients without any risk factors (steroids, anastomotic tension). The laparoscopic approach can be used safely in children. The rate of complications may be less than for open surgery, and the cosmetic results are definitely superior."

quote from "Pediatric Surgery (Springer Surgery Atlas)" by Prem Puri, Michael E. Höllwarth - "For the surgical management of umbilical polyp, limited exploration of the peritoneal cavity is advisable, because of the possibility of an underlying connection to the ileum by a remnant of the omphalomesenteric duct. The approach is via a circumferential incision around the polyp, trying to preserve as much of the normal umbilicus as possible. The skin defect is repaired using an absorbable purse-string suture. A subumbilical incision is made as described above. The abdominal wall is opened transversely and the peritoneal cavity is entered. If an omphalomesenteric duct remnant is present, it is resected."
