Intestinal atresia and stenosis: a 25-year experience with 277 cases

OBJECTIVE

To evaluate the causes, clinical presentation, diagnosis, operative management, postoperative care, and outcome in infants with intestinal atresia.

DESIGN

Retrospective case series.

SETTING

Pediatric tertiary care teaching hospital.

PATIENTS

A population-based sample of 277 neonates with intestinal atresia and stenosis treated from July 1, 1972, through April 30, 1997. The level of obstruction was duodenal in 138 infants, jejunoileal in 128, and colonic in 21. Of the 277 neonates, 10 had obstruction in more than 1 site. Duodenal atresia was associated with prematurity (46%), maternal polyhydramnios (33%), Down syndrome (24%), annular pancreas (33%), and malrotation (28%). Jejunoileal atresia was associated with intrauterine volvulus, (27%), gastroschisis (16%), and meconium ileus (11.7%).

INTERVENTIONS

Patients with duodenal obstruction were treated by duodenoduodenostomy in 119 (86%), of 138 patients duodenotomy with web excision in 9 (7%), and duodenojejunostomy in 7 (5%) A duodenostomy tube was placed in 3 critically ill neonates. Patients with jejunoileal atresia were treated with resection in 97 (76%) of 128 patients (anastomosis, 45 [46%]; tapering enteroplasty, 23 [24%]; or temporary ostomy, 29 [30%]), ostomy alone in 25 (20%), web excision in 5 (4%), and the Bianchi procedure in 1 (0.8%). Patients with colon atresia were managed with initial ostomy and delayed anastomosis in 18 (86%) of 21 patients and resection with primary anastomosis in 3 (14%). Short-bowel syndrome was noted in 32 neonates.

MAIN OUTCOME MEASURES

Morbidity and early and late mortality.

RESULTS

Operative mortality for neonates with duodenal atresia was 4%, with jejunoileal atresia, 0.8%, and with colonic atresia, 0%. The long-term survival rate for children with duodenal atresia was 86%; with jejunoileal atresia, 84%; and with colon atresia, 100%. The Bianchi procedure (1 patient, 0.8%) and growth hormone, glutamine, and modified diet (4 patients, 1%) reduced total parenteral nutrition dependence.

CONCLUSIONS

Cardiac anomalies (with duodenal atresia) and ultrashort-bowel syndrome (<40 cm) requiring long-term total parenteral nutrition, which can be complicated by liver disease (with jejunoileal atresia), are the major causes of morbidity and mortality in these patients. Use of growth factors to enhance adaptation and advances in small bowel transplantation may improve long-term outcomes.

Duodenal atresia and stenosis: long-term follow-up over 30 years

BACKGROUND

Duodenal atresia and stenosis is a frequent cause of congenital, intestinal obstruction. Current operative techniques and contemporary neonatal critical care result in a 5% morbidity and mortality rate, with late complications not uncommon, but unknown to short-term follow-up.

METHODS

A retrospective review of patients with duodenal anomalies was performed from 1972 to 2001 at a tertiary, children's hospital to identify late morbidity and mortality.

RESULTS

Duodenal atresia or stenosis was identified in 169 patients. Twenty children required additional abdominal operations after their initial repair with average follow-up of 6 years (range, 1 month to 18 years) including fundoplication (13), operation for complicated peptic ulcer disease (4), and adhesiolysis (4). Sixteen children underwent revision of their initial repair: tapering duodenoplasty or duodenal plication (7), conversion of duodenojejunostomy to duodenoduodenostomy (3), redo duodenojejunostomy (3), redo duodenoduodenostomy (2), and conversion of gastrojejunostomy to duodenoduodenostomy (1). There were 10 late deaths (range, 3 months to 14 years) attributable to complex cardiac malformations (5), central nervous system bleeding (1), pneumonia (1), anastomotic leak (1), and multisystem organ failure (2).

CONCLUSIONS

Late complications occur in 12% of patients with congenital duodenal anomalies, and the associated late mortality rate is 6%, which is low but not negligible. Follow-up of these patients into adulthood is recommended to identify and address these late occurrences.

Neonatal short bowel syndrome

In this retrospective study the management of infants who had undergone resection of more than 50% of the small bowel as newborn infants between 1970 and 1988 was analyzed to define prognostic factors. Small bowel resections were performed for atresia (36 cases), volvulus (22 cases), gastroschisis (10 cases), necrotizing enterocolitis (11 cases), and other disorders (8 cases). Patients were classified into two groups depending on the length of residual small bowel: group 1 (n = 35) had less than 40 cm of small bowel and group 2 (n = 51) had 40 to 80 cm of residual small bowel. Patients in group 2 had significantly better survival rates than those in group 1 (92.0% vs 66.6%; p less than 0.001). The patients in group 1 who were born after 1980, when home parenteral nutrition was introduced, had better survival rates than those who were treated before 1980 (95.0% vs 65.0%; p less than 0.01). The time required for acquisition of intestinal adaptation depended on the intestinal length (average, 27.3 months for group 1 and 14 months for group 2; p less than 0.01) and on the presence or absence of the ileocecal valve. Parenteral or supportive enteral nutrition, or both, ensured normal growth in both groups. We conclude that more than 90% of infants now survive after extensive small bowel resection with parenteral nutrition and that the remaining small intestine will adapt with time. Home-based parenteral nutrition allowed children to be treated in the best psychosocial environment.

Duodenal atresia and stenosis: reassessment of treatment and outcome based on antenatal diagnosis, pathologic variance, and long-term follow-up

Duodenal atresia and stenosis was observed in 103 infants and children from 1972 to 1991. There were 59 girls and 44 boys. Atresia was noted in 79 instances and stenosis in 24. Maternal hydramnios was detected in 33 cases, 46 babies were premature, and 31 had Down's syndrome. Fifty-four infants had significant associated anomalies including 35 with cardiac defects. Diagnosis was achieved by prenatal ultrasound examination in 14 cases, observation of a double-bubble sign on abdominal radiograph in 73, and contrast studies in 30 infants including 24 with stenosis. At operation annular pancreas was noted in 37 cases, malrotation in 37 cases, anterior portal vein in 4, and a second web in 3. Surgical treatment included duodenoduodenostomy in 85, duodenotomy and web excision in 8, and duodenojejunostomy in 10. Operative survival was 95%. Deaths were related to complex cardiac defects. Despite antenatal diagnosis, prompt intervention, and apparent early surgical success (95% survival), late deaths (5%) and late complications including motility disorders, megaduodenum, gastroesophageal reflux, duodenal-gastric reflux, gastritis, peptic ulcer disease, blind loop syndrome, and biliary-pancreatic conditions may be observed months to years after management during the neonatal period. Modifications in surgical technique including early tapering duodenoplasty may be useful, and close long-term follow-up is an essential component of patient care.

Malrotation and intestinal atresias

This review encompasses four congenital conditions which present with symptoms of bowel obstruction in the neonatal period. The antenatal and postnatal features of malrotation, jejuno-ileal atresia, duodenal atresia and colonic atresia are discussed. Each condition is outlined including the classification, epidemiology, aetiology and presentation, and a summary of the surgical management is described.

The natural history of meconium peritonitis diagnosed in utero

The authors reviewed their experience with meconium peritonitis (MP) diagnosed in utero to define criteria for prenatal and postnatal management. Prenatal diagnosis was made by identifying abdominal calcification on serial ultrasound examinations in nine fetuses, between 18 and 37 weeks' gestation. Cases without associated bowel abnormalities were considered "simple MP" and those with bowel abnormalities were considered "complex MP." Five cases of simple MP were identified at 18, 23, 30, 34, and 37 weeks' gestation. These five fetuses were delivered at term and had normal abdominal examinations. Abdominal radiographs were obtained in three showing normal bowel gas patterns, and abdominal calcifications in only two. All five patients were fed uneventfully. Four cases of complex MP were identified at 26, 26, 31, and 31 weeks' gestation. All four fetuses had dilated loops of bowel. Two of the four had meconium cysts, one of which was associated with ascites and the other with polyhydramnios. Shortly after birth both infants with meconium cysts required ileal resection and ileostomy for ileal atresia and ileal perforation, respectively. The remaining two infants had no evidence of dilated bowel, meconium cyst, or ascites on postnatal radiograph and were fed uneventfully. These data suggest that only 22% of fetuses with a prenatal diagnosis of MP develop complications that require postnatal operation. Gestational age at diagnosis does not correlate with postnatal outcome. Fetuses with complex MP are at increased risk for postnatal bowel obstruction and perforation.

Diamond-shaped anastomosis for duodenal atresia: an experience with 44 patients over 15 years

During the period between 1974 and 1988 44 patients were treated for congenital intrinsic duodenal obstruction using a diamond-shaped anastomosis (35 atresias, including two multiple atresias and nine stenoses). Neither gastrostomy nor transanastomotic tube was used. Postoperatively, oral feeding was started on days 2 to 6 (3.66 +/- 1.41 day). Intravenous fluid administration was discontinued on days 3 to 20 (7.54 +/- 3.58 day). Fourteen patients died, none related to the operative procedure. Of 30 survivors, 21 patients have been followed from 6 months to 15 years. Body weight was within the normal range at the latest visit. Current barium study performed in 19 patients showed no blind loop, megaduodenum, or anastomotic malfunction. The diamond-shaped anastomosis provides the following advantages: (1) early recovery of anastomotic function, and (2) avoidance of later complications, such as formation of a blind loop or anastomotic stenosis.

Short-bowel syndrome: a collective review

Neonates can now be expected to survive with very short lengths of bowel because of advances in pediatric neonatal care and in parenteral and enteral nutrition. Most pediatric surgeons have only a few patients with this problem under their care, so individual experience is limited. This collective survey, carried out by postal questionnaires to pediatric surgeons in the British Association of Paediatric Surgeons in the United Kingdom with an interest in the gastrointestinal tract, documents current techniques of management, the complications encountered, and reviews the clinical and economic consequences of prolonged total parenteral nutrition. We conclude that within the limitations of resources and our understanding of prognosis, neonates, especially if less than 35 weeks' gestation, with remaining jejunoileal segment of greater than 20 cm with an intact ileocecal valve (ICV) or greater than 30 cm without an ICV, should be considered salvageable.

Management of intestinal atresia in patients with gastroschisis

BACKGROUND/PURPOSE

Intestinal atresia occurs in approximately 10% to 20% of children with gastroschisis and may be missed at the initial closure if a thick peel obscures the bowel. Some investigators have identified intestinal atresia as a significant contributor to morbidity and mortality. The authors reviewed their experience with gastroschisis and intestinal atresia in an attempt to answer the following questions. What is the incidence of this association? How often is the intestinal atresia unrecognized as a result of the peel? What is the optimal management for infants with atresia and gastroschisis, and does the atresia affect morbidity or mortality?

METHODS

The hospital charts and medical records of all patients with gastroschisis treated at our institution from 1969 to present were reviewed thoroughly. Parameters analyzed included gestational age (GA), birth weight (BW), antenatal diagnosis, mode of delivery, type of closure, era of repair, presence of other major anomalies, and development of necrotizing enterocolitis. Morbidity and mortality rates were examined. Characteristics of patients with and without atresia were compared. Chi-squared was used for crosstabular analysis. Sample parameters were compared with Student's t test. P values of less than.05 were considered significant.

RESULTS

A total of 199 babies had gastroschisis and 25 (12.6%) had intestinal atresia. Intestinal atresia was initially unrecognized in 3 patients. Most patients (80%) underwent primary closure of the abdominal wall. Initial stoma formation and delayed anastomosis was performed in 12 (48%) patients, none of whom required prosthetic material for abdominal wall closure. Initial stomas were avoided in 5 patients who required SILASTIC (Dow Corning, Midland, MI) silos. Skin closure alone was used in 2 babies. The level of the atresia was most commonly jejunoileal (20 of 25, 80%). Mean hospital stay was increased in babies with intestinal atresia, 36.2 versus 63.1 days (P <.001).

CONCLUSIONS

Although patients with intestinal atresia did have feeding delays, an increased incidence of adhesive intestinal obstruction, and prolonged hospitalization, neither chi(2) nor logistic regression analysis showed any correlation with mortality. Intestinal repair at the first operation is sometimes possible and depends on the severity of the peel. Delayed repair of the atresia after a period of bowel decompression and parenteral nutrition is preferred, but in certain situations (colonic atresia, necrotic intestine, complicated atresia) may not be possible. The combination of stomas and prosthetic material can be avoided in almost all patients. A management algorithm for patients with atresia and gastroschisis is discussed.

Intestinal obstruction in neonatal/pediatric surgery

Intestinal obstruction in the newborn infant and older child may be due to a variety of conditions, including atresia and stenosis, annular pancreas, malrotation, duplication cyst, meconium ileus, meconium plug syndrome and neonatal small left colon syndrome, Hirschsprung's disease, neoplasia, trauma, and other rarer causes. The mode of presentation can be acute or more chronic with systemic upset due to shock. Neonates, more so than older children, with unrecognized intestinal obstruction deteriorate rapidly, show an increase of associated morbidity and mortality and appropriate surgical treatment becomes more hazardous. Early diagnosis depends largely on the prompt detection of obstructive manifestations by the clinician and the subsequent accurate interpretation of radiographic findings and other investigations, leading to definitive treatment, which should always be preceded by appropriate resuscitation/preparation of the infant/child. Management of intestinal obstruction will almost always be surgical, apart from some notable exceptions and all are discussed in more detail. With the advent of pediatric and neonatal intensive care and multidisciplinary care, the morbidity and mortality of cases of intestinal obstruction reported in current series is generally extremely low and mainly determined by the coexistence of other major congenital anomalies (eg, cardiac), delays in diagnosis and treatment or coexisting medical conditions. Newer treatments and future developments may reduce the residual mortality in such cases as ultrashort-bowel syndrome.

Adaptation in short-bowel syndrome: reassessing old limits

The improving survival of patients with severe short-bowel syndrome along with the advent of successful intestinal transplantation have accentuated the need to answer two questions. (1) Is there an intestinal length below which adaptation to full enteral nutrition can not be expected to occur? (2) How much time is necessary to complete intestinal adaptation? We reviewed the outcome of 21 infants with less than 50 cm of small intestine to answer these questions. Patients were divided into three groups based on intestinal length, regardless of ileocecal valve status: group I, < 10 cm (n = 3); group II, 10 to 30 cm (n = 11); and group III, 30 to 50 cm (n = 7). Data were collected to assess survival, incidence of adaptation, time to adaptation, and causes of mortality. Infants in group I did not achieve intestinal adaptation to full enteral nutrition. One survived and 2 died, one from varicella pneumonia and the other after intestinal transplantation. Eight of the 11 (73%) patients in group II survived and 5 of 8 (63%) survivors achieved full intestinal adaptation after a mean interval of 320 days (range, 148 to 506 days) on parenteral nutrition. Six of the seven patients (86%) in group III survived and all survivors (100%) achieved complete enteral adaptation after an average of 376 days (range, 58 to 727 days). The overall survival was 71% (15/21), but survival in patients with > 10 cm was 78%.(ABSTRACT TRUNCATED AT 250 WORDS)

Laparoscopic duodenoduodenostomy in the neonate

BACKGROUND

Minimally invasive procedures are performed in neonates for an ever-expanding list of congenital anomalies. The laparoscopic repair of duodenal atresia and stenosis in the neonate is one such indication.

METHOD

We report our experience with the laparoscopic duodenoduodenostomy for duodenal atresia and stenosis in the neonate over the past 4 years. A retrospective chart review was conducted on all cases of duodenal atresia and stenosis diagnosed at our center between January 2004 and January 2008.

RESULTS

Seventeen neonates underwent laparoscopic duodenoduodenostomy successfully during the period. Patient weight at surgery ranged from 1.35 to 3.75 kg. Most were operated on within the first week of life. Many had associated anomalies. There were no conversions to an open procedure, no intraoperative complications, and no anastomotic leaks observed. Time to full feeds averaged 12 days.

CONCLUSIONS

Laparoscopic duodenoduodenostomy in the neonate can be safely and successfully performed with excellent short-term outcome.

Laparoscopic duodenoduodenostomy for duodenal atresia

A 3,220-g newborn baby with trisomy 21 presented with duodenal atresia. No other congenital malformations were diagnosed. Informed consent for a laparoscopic approach was obtained. The child was placed in a supine, head-up position slightly rotated to the left at the end of a shortened operating table. The surgeon stood at the bottom end with the cameraperson to his left and the scrub nurse to his right. The screen was at the right upper end. Open insertion of a cannula for a 5-mm 30 degrees telescope through the inferior umbilical fold was performed. A carbon dioxide (CO2) pneumoperitoneum with a pressure of 8 mmHg and a flow of 2l/min was established. Two 3.3-mm working cannulas were inserted; one in the left hypogastrium and one pararectally on the right at the umbilical level. Two more such cannulas were inserted; one under the xyphoid for a liver elevator and one in the right hypogastrium for a sucker. Mobilization of the dilated upper and collapsed lower duodenum was easy. After transverse enterotomy of the upper duodenum and longitudinal enterotomy of the distal duodenum, a diamond-shaped anastomosis with interrupted 5 zero Vicryl sutures were performed. The absence of air in the bowel beyond the atresia increased the working space and greatly facilitated the procedure. The technique proved to be easy, and the child did very well. Laparoscopic bowel anastomosis in newborn babies had not been described previously. Recently, a diamond-shaped duodenoduodenostomy for duodenal atresia was performed. The technique proved to be simple and is described in detail. The child did very well.

Atresia of the colon

BACKGROUND/PURPOSE

Colonic atresia (CA) is one of the rarest causes of neonatal intestinal obstructions, and no large series can be reported. Therefore, we did perform a retrospective clinical trial to delineate our CA cases and carry out a literature survey.

METHODS

We reviewed the charts of CA cases treated in our center between 1992 and 2002. We aimed to collect all reported cases in Medline, and personal communications with the authors of published series were used to reach the missing data.

RESULTS

The chart review revealed 9 newborns with CA treated in our center (6 cases of type III, 2 cases of type II, and 1 case of type IV). These accounted for 3.7% of all gastrointestinal atresias managed in our center. Of the CA cases, 3 were isolated and 6 had at least one or more associated congenital anomalies. The preferred surgical technique at the initial treatment of CA was performing a proximal stoma and distal mucous fistula in an average of postnatal 59.4 hours. The literature survey enabled us to reach 224 cases of CA, including our cases.

CONCLUSIONS

Because of the low incidence of CA, delay in diagnosis and treatment may occur. The mortality is statistically higher when the surgical management is performed after 72 hours of age. However, the prognosis of CA is satisfactory if diagnosis and surgical management could be made promptly and properly.

Intestinal plication in the treatment of atresia

Twelve infants with jejunal atresia were managed by plication of the dilated proximal bowel and end-to-oblique anastomosis. The technique is simple and very effective in preventing functional obstruction of the dilated bowel, and it preserves the mucosal absorptive surface. It is easier to perform and seems to allow earlier return of function than resection or tapering of the dilated jejunum.

Jejunoileal atresia: a proposed classification

An experience with 59 infants with jejunal and ileal atresia is presented along with a proposed classification based on a combination of morphology and clinical characteristics. It would appear that the characteristics of each type are sufficiently distinct as to render this worthwhile classification.

Tapering enteroplasty in infants with bowel atresia and short gut

Antimesenteric tapering enteroplasty was evaluated as an alternative to resection in 16 babies. Tapering enteroplasty was done for jejunal atresia (11), ileal atresia (three), total colonic aganglionosis (one), and colonic atresia (one). Most had short gut with proximal bowel dilation. There were no anastomotic leaks but slight functional delay (eight to 14 days). One patient with 14 jejunoileal atresias received continuous-drip feeding while the remainder took regular diet. Mean weight gain was in the 25th percentile at 1 year of age, and the 35th percentile at 2 years of age. There were two deaths from liver failure and brain damage. Antimesenteric tapering enteroplasty is particularly useful in selected instances of intestinal atresia associated with short gut, where preservation of bowel length may be essential for survival. Gastrointestinal function, bowel movement patterns and growth and development have been gratifying.

Contemporary management of meconium ileus

Meconium ileus was noted as an early manifestation of cystic fibrosis in 60 neonates between 1972 and 1991. There were 20 girls and 40 boys. A family history of cystic fibrosis was present in six children. Twenty-five neonates had uncomplicated meconium ileus due to inspissated meconium within the terminal ileum. Thirty-five neonates presented with 56 complications of meconium ileus, including volvulus (n = 22), atresia (n = 20), perforation (n = 6), and giant cystic meconium peritonitis (n = 8). Clinical presentation included abdominal distension, bilious vomiting, and failure to pass meconium. In two recent cases, prenatal ultrasonography detected a mass with proximal bowel distension indicative of cystic meconium peritonitis. Mechanical bowel obstruction in the other neonates was diagnosed from plain abdominal radiographs and barium enema. Ten patients with uncomplicated meconium ileus were successfully treated with a diatrizoate meglumine (Gastrografin) enema. The remaining 15 patients required a laparotomy, with 9 treated by bowel resection and enterostomy and 6 recent cases managed with enterotomy and irrigation. Complicated cases were managed by bowel resection and anastomosis (n = 15) or enterostomy (n = 20). Survival at 1 year was 92% in patients with uncomplicated meconium ileus and 89% for those with complicated meconium ileus. The therapy of choice for uncomplicated meconium ileus is nonoperative Gastrografin enema, with enterotomy and irrigation reserved for enema failures. Complicated cases require exploration and, in the absence of giant cystic meconium peritonitis, are usually amenable to bowel resection and primary anastomosis.

Impact of intestinal lengthening on the nutritional outcome for children with short bowel syndrome

Survival among children with short bowel syndrome has increased with the use of supportive nutritional techniques including parenteral and enteral nutrition. Further improvement in outcome has been sought by using intestinal lengthening procedures to lengthen the bowel, improve intestinal motility, initiate a progressive increase in intestinal mucosal mass, and thereby improve tolerance to enteral nutrition. The authors examine the growth parameters and the tolerance to enteral nutrition in children with refractory short bowel syndrome before and after intestinal lengthening procedures. For seven children, the percentage of calories from enteral nutrition, the medical and surgical complications, and the number of days in the hospital (1 year before and 2 years after the lengthening procedure) were evaluated. The mean birth weight was 1,991 g (range, 1,198 to 3,096 g). The initial diagnoses requiring bowel resection included necrotizing enterocolitis, multiple small bowel atresias, gastroschisis with midgut volvulus, cloacal exstrophy, and long-segment Hirschsprung's disease. The mean length of the residual small bowel was 49 cm (range, 6 to 92 cm). All but one child had surgical resection of the ileocecal valve. The percentage of enteral nutrition calories significantly increased by 9 months after the procedure (P < .008, analysis of variance). Only one child has been completely weaned from parenteral nutrition. All children's growth parameters have been maintained or improved (weight/age, height/age, and weight/height). Few major medical and surgical complications have been observed. Central venous catheter infection has been the most common medical complication. The mean number of hospitalization days decreased during the second year after the lengthening procedure. The authors conclude that the intestinal lengthening procedure enhances the tolerance for enteral nutrition, improves the nutritional status, and decreases the need for hospitalization. The procedure should be considered for children with refractory short bowel syndrome who require prolonged parenteral nutrition.

Long-term nutritional and clinical outcomes after serial transverse enteroplasty at a single institution

PURPOSE

Serial transverse enteroplasty (STEP) is a novel technique to lengthen and taper bowel in patients with intestinal failure. First described in 2003, initial data and reports have demonstrated favorable short-term outcomes, but there is limited published data on long-term outcomes of the procedure. Our aim was to assess clinical and nutritional outcomes after the STEP procedure.

METHODS

After obtaining institutional review board approval, we reviewed all records of patients (n = 16) who underwent the STEP procedure at our institution from February 2002 to February 2008. Patients were observed for a median time of 23 months (range, 1-71) postoperatively. Analyses of z scores for weight, height, and weight-for-height, and progression of enteral calories were performed using longitudinal linear models with random effects.

RESULTS

Of the 16 patients (10 male), the median age at time of surgery was 12 months (interquartile range, 1.5-65.0). The mean increase in bowel length was 91% +/- 38%. After the STEP procedure, patients had increased weight-for-age z scores of 0.03 units per month (P = .0001), height for age z scores of 0.02 units per month (P = .004), and weight-for-height z scores of 0.04 units per month (P = .02). Patients had improved enteral tolerance of 1.4% per month (P < .0001). Six patients (38%) transitioned off parenteral nutrition (median, 248 days). Long-term complications included catheter-related bacteremia (n = 5), gastrointestinal bleeding (n = 3), and small bowel obstruction (n = 1). Two patients ultimately underwent transplantation. There were no deaths.

CONCLUSIONS

In pediatric patients with intestinal failure, the STEP procedure improves enteral tolerance, results in significant catch-up growth, and is not associated with increased mortality.

Congenital pyloric atresia and associated anomalies

Congenital pyloric atresia (CPA) is a very rare condition that was first described by Calder in 1749. Commonly, CPA occurs as an isolated lesion, which has an excellent prognosis, but it can also be seen in association with other malformations, which can have a negative impact on the final outcome. The medical records of all patients with the diagnosis of CPA treated at our hospital were retrospectively reviewed for: age at diagnosis, sex, presenting symptoms, history of polyhydramnios, diagnosis, associated anomalies, operative findings, treatment and outcome. Eleven cases with the diagnosis of CPA were treated at our hospital. There were five males and six females. Seven were products of full term normal vaginal delivery and the remaining four were prematures. Their birth weights ranged from 1.2 to 3.9 kg (mean 2.2 kg). Polyhydramnios was seen in seven (63.6%). Associated anomalies were seen in six (54.5%). These included epidermolysis bullosa (EB) in three, hereditary multiple intestinal atresias (HMIA) in two including a duplication cyst in one of them, esophageal atresia in one, Down's syndrome in one, congenital heart disease in one, cleft palate in one and aplasia cutis congenital (ACC) in one. Intraoperatively, five had pyloric diaphragms, in two of them there were double diaphragms, three had pyloric atresia with a gap between the two ends and two had pyloric atresia with no gap. One of them had duodenal perforation as well as ileal perforation. The patients with pyloric diaphragms had excision of diaphragms and Heineke-Mickulicz pyloroplasty. Four of the other five patients had gastro-duodenostomy. One of them also had duodeno-jejunostomy due to associated distal duodenal atresia and excision of duplication cyst. The patient with duodenal and ileal perforation and because of the marked distension of the duodenum had reduction duodenoplasty, gastroduodenostomy, and duodeno-jejunostomy. The area of ileal perforation was resected and end-to-end anastomosis was done after correction of the associated malrotation. One patient with associated esophageal atresia had gastrostomy and gastrojejunostomy. Post-operatively, all did well initially, but subsequently, six of them died giving an overall survival of 45.5%. Sepsis was the cause of death in all of them. CPA is very rare and when it occurs in isolation it has a good prognosis. The association of CPA with HMIA is universally fatal. CPA in association with EB has a high mortality but there are encouraging results with the use of steroids and phenytoin. Sepsis continues to be the main cause of death and an associated combined immunodeficiency should be excluded.
