After cystoprostatectomy for cancer of the bladder 43 men were provided with a detubularized, low pressure ileal reservoir (Kock pouch) connected to the urethra. Reflux was prevented by an intussusception valve. There was no operative mortality and few early complications. At followup the mean postoperative observation time was 13 months, with a range of 5 to 20 months. Late complications included manifestations of local tumor recurrence or distant metastases in 9 patients within 6 months postoperatively, which made adequate functional evaluation impossible. In 18 patients reflux to the upper urinary tract due to eversion or sliding of the antireflux valve occurred at various postoperative intervals. In 16 of these patients incontinence developed as a consequence of the reflux. Surgical correction of the failing antireflux valve restored reflux prevention and continence. Within 3 to 6 months the capacity of the reservoirs had reached an ultimate volume of approximately 600 ml. Pressure waves exceeding 40 cm. water seldom occurred in the mature reservoirs and then only at high filling volumes. The mean urethral resting resistance to flow was 64 cm. water. The configuration and function of the upper urinary tract improved or stabilized postoperatively. Of 34 evaluable patients 30 were continent during the day with a voiding frequency of 3 to 5 times and dry at night with a frequency of 0 to 2.

The ability to detect ileocolic intussusception on the supine cross-table lateral radiograph of the abdomen in infants was prospectively evaluated in 12 cases (including two recurrences) over a 2-year period. The intussusceptions (including one recurrence) were directly depicted on five radiographs as a homogeneous water-density mass producing a convex interface with bowel gas at the anterior part of the abdomen. In another four patients, the intussusception produced an inappropriate craniocaudal separation of gas-filled bowel loops in the upper part of the abdomen, caudal to the liver shadow. The intussusception was prospectively recognized on the supine cross-table lateral radiograph in nine of 12 cases.

In 1741, Nicolas Andry, counsellor of King Louis XV, published a book about "orthopedics," inventing this word. The book is interesting as the author refers to beliefs and habits of the time. In 1864, Guersant published Notes About Pediatric Surgery, a real textbook which was translated into English and German and dealt with the importance of children's psychological training, anesthesia, and water or mother's milk after the operation, and also described tracheotomy, draining of cervical adenitis, and lithotrity. The classification of bone affections was still very confused. Tuberculosis and syphilis have an important place; hypospadias is not treated by surgery. In 1905, Froehlich published Pediatric Surgery Studies dealing exclusively with visceral surgery and demonstrating progress compared to Guersant's study. In 1906, Kirmisson published Pediatric Surgical Textbook, containing the first discussion of radiology and the description of the pathology of the omphalomesenteric duct and of other congenital malformations. Osteomyelitis was given its proper name, and cervical fistulas were explained. In 1914, A. Broca achieved further progress describing treatments of megacolon, intussusception, and the operation of Fredet Ramstedt. The book by Ombredanne, already out of date at the time of its publication, showed that he was not aware of the wartime, progress achieved by Ladd and Gross in the USA. French publications have diminished since then, and French pediatric surgery is still trying to find a precise identity.

A new model for diverting urine to the rectum was tried in dogs. An intussusception valve was constructed at the junction of the sigmoid colon and the rectum allowing passage only in aboral direction. The rectum was augmented by patching it with an opened and folded ileal segment. The ureters were implanted into the rectum by a new anti-reflux method. All three dogs survived the operation. The volume of the augmented rectum increased from 80-150 ml at operation to a maximum of 750 ml six months after the operation. The pressure in the rectum did not exceed 18 cm of water during maximal filling. No reflux to the bowel proximal to the intussusception valve or to the ureters could be observed even during maximal filling of the augmented rectum. No signs of obstruction of the fecal stream by the intussusception valve were seen. In three out of five implanted renal units strictures developed at the implantation sites and resulted in impaired renal function. In the two renal units without strictures, no impairment of kidney function was found. Involuntary leak from the anus was not observed and no masceration was found around the anus. These experiments are regarded as very encouraging an a clinical trial is now under way.

A new method for urinary diversion to the rectum was elaborated in animal experiments and currently has been used in 19 patients. Reflux of the rectal content to the colon and to the upper urinary tract is prevented by the fashioning of an intussusception valve at the rectosigmoid junction. The rectum is augmented by anastomosing an ileal patch to the anterior rectal wall. A transverse colostomy protects the construction for 6 to 8 weeks. Of the 19 patients 3 had local recurrence or metastasis within 6 months. Thus, 16 patients with a followup of 3 to 14 months are evaluable. All patients are continent during the daytime with an emptying frequency of 3 to 5 times and dry at night with a frequency of 0 to 2. In 3 patients partial sliding of the sigmoid intussusception valve occurred causing reflux of rectal contents to the sigmoid and to the right ureter in 1. Reflux to the upper urinary tract has not been revealed in any of the other patients. With 1 exception excretory urography has demonstrated either improvement or stabilization of the upper urinary tract post-operatively. The rectal capacity increased from 200 to 700 ml. after 6 months. With the reservoir full the mean basal pressure was 17 cm. water and the mean maximum pressure was 24 cm. water.

Typhlitis is a necrotising inflammation of the caecum usually found in acute leukaemic patients on chemotherapy. We described the radiological features of two children with this complication. The first was diagnosed by an enema using water-soluble contrast medium and the second by ultrasound and computed tomography (CT). A water-soluble contrast medium enema is considered diagnostic in this clinical context and excludes intussusception and, often, appendicitis. Ultrasound showed a rounded mass with dense central echoes and a wider hypoechoic periphery. Computed tomography showed the long segment of thick-walled ascending colon and caecum; if perforation is suspected, ultrasound and CT might be preferable to a contrast enema.

Intussusception valves were created in the small intestine of jejunoileal bypass-operated dogs and patients with the intention to prevent reflux of chyme into the excluded intestinal loop and thereby increase weight loss. In the dogs the valves were shown to withstand a pressure of at least 100 cm of water. All patients with end-to-side bypass were at X-ray examination found to have sufficient valves whereas only four of fourteen with end-to-end bypass, where the defunctionalized loop was implanted into the cecum, had tight valves. During five years of observation no significant difference in weight loss was seen between the patients with valves and control groups without valves. It is concluded that reflux of chyme only plays a minor role for weight loss after jejunoileal bypass for obesity.

Computed tomographic evaluation of ileocolic intussusception in an adult is presented. Upper gastrointestinal series with orally administered water-soluble contrast agent suggested obstruction in the lower part of the small intestine, but computed tomography made a definitive diagnosis. Pathognomonic CT findings of ileocolic intussusception are presented.

Three cases of perforation of the colon distal to an ileocolic intussusception are presented. Two cases were associated with attempted hydrostatic reduction of the intussusception, while the other was discovered at operation. The mechanism of this complication is not clear. When performing a contrast enhanced examination of the colon and there is a risk of perforation: (a) dilute water-soluble contrast medium should be used; (b) special attention should be paid to the colon distal to the intussusception; and (c) should contrast material be observed in the peritoneal cavity, the enema reservoir should immediately be lowered to the floor to siphon off the liquid from the colon.

A transverse colonic conduit incorporating an intussusception valve and skin-flapped cutaneous aperture was constructed in nine patients with combined faecal incontinence and disordered evacuation. Intestinal continuity was restored with a colocolonic anastomosis. Median follow-up was 4 (range 2-15) months and daily irrigation with a median of 1.2 (range 0.3-2.0) litres of water resulted in evacuation in less than 1 h. At 1 month after operation there was no leakage of solid or liquid faeces from the anus between irrigations. The valve was continent to faeces and irrigation fluid, and no stoma appliances were required.
