Clinicopathologic Features of Childhood Rhabdomyosarcoma and Treatment Outcomes in Ibadan, Nigeria: A 10-year Review.

The objectives of this study were to describe the clinicopathologic features and treatment outcomes of childhood rhabdomyosarcoma in a resource-constrained setting. All cases of childhood rhabdomyosarcoma seen over a 10-year period (July 2006 to June 2016) at the University College Hospital, Ibadan, Nigeria were reviewed. Data were extracted from the database of the pediatric Hematology/Oncology Unit of the hospital and analyzed. Ethical approval was obtained from the Institutional Ethics Committee. Fifty children were seen comprising 30 men and 20 women with bimodal ages of 4 and 5 years. Median duration of illness was 16 weeks and the most common primary tumor site was the head-and-neck region in 27 (54%) of cases. The histologic subtypes were embryonal in 30 (60%), alveolar in 9 (18%), and not specified in 11 (22%). The Intergroup Rhabdomyosarcoma Study group TNM Pretreatment stages were stage I in 15 (30%), stage III in 17 (34%), and stage IV in 18 (36%). Treatment included chemotherapy, surgery, and radiotherapy and abandoned in 20 (40%) cases. Median survival was 45 weeks (95% confidence interval: 16.4-73.6) and 5 (10%) patients were alive and disease free, 4 years or more after diagnosis. Outcome of childhood rhabdomyosarcoma is poor and early diagnosis and improved access to treatment are recommended.

Syngnathia.

Syngnathia is a congenital fusion of the upper and lower jaws. Its occurrence poses a significant challenge to feeding and its management is challenging to both the surgeon and the anaesthetist. Reports in the literature are mainly clinical reports or case series. To the knowledge of the authors and from the available literature, this is only the fourth report from Nigeria. The presentation and successful management of a Nigerian female neonate with congenital syngnathia is described and reviewed with literature.

Global Strategies for Postoperative Care and Bowel Management in Patients With Anorectal Malformations: Varied Practices and Barriers.

BACKGROUND: Anorectal malformations (ARMs) commonly result in constipation and fecal incontinence following primary surgical reconstruction. This study investigates global variations in postoperative care and resources. METHODS: A survey was distributed via the International Pediatric Endosurgery Group (IPEG) and snowball sampling. Geographically, respondents were categorized into high-income countries (HICs) and low-or middle-income countries (LMICs). RESULTS: 233 surveys were received, 64% from LMICs and 36% from HICs. Of these, 51% reported monitoring ARM patients for over a year, while 23% utilized digital technologies. Access to anesthesia for anorectal exams was available to 70% of respondents. Only 29% had established a one-week Bowel Management Program (BMP). Collaboration with urologists and gynecologists was more prevalent in HICs (59%) compared to LMICs (37%, p < 0.01). In HICs, nurses and advanced practice providers were significantly more involved in BMP (71% vs. 39% in LMICs; p < 0.01), and abdominal radiographs for regimen adjustments were used more frequently (80% vs. 69% in LMICs; p = 0.03). Treatment regimens were more varied in HICs, and quality of life tracking was more consistent (19% vs. 9% in LMICs; p = 0.02). LMICs reported significant shortages of medications and equipment (75% vs. 58% in HICs; p = 0.01), inadequate sanitation (48% vs. 24%; p < 0.01), and insufficient insurance coverage (58% vs. 44%; p = 0.04). CONCLUSIONS: There are notable global disparities in the postoperative care of ARM patients, particularly in BMP protocols and treatment regimens, with LMICs facing severe socioeconomic challenges. This emphasizes the urgent need for targeted strategies and resources to enhance outcomes for ARM patients across different regions. LEVEL OF EVIDENCE: Level III.

Outcome of retained intra-abdominal foreign body managed in a general surgical service in Ibadan: a case series.

Retained intra-abdominal foreign bodies are rare and most occur following abdominal or gynaecological surgery. Sponges are the most retained foreign body. The foreign bodies range from surgical instruments, including abdominal pads and gauze to artery forceps; to a pen cap. Retained objects can also be self-inserted. The authors report a case series on the outcome of retained foreign bodies in the intra-abdominal cavity managed in the general surgery service of the University College Hospital, Ibadan over 12-years.

Study protocol for a pilot quasi-experimental study on oral health education for nurses and community health workers in Nigeria.

Introduction: The primary health care system provides an ideal setting for the integration of oral health into general health care as well as equitable access to oral health care. However, the limited oral health knowledge of primary health care workers necessitates appropriate training before they can participate in health promotion efforts. This pilot training was designed to examine the impact of the Oral Health Education module for Nurses and Community Health Care Workers on their oral health awareness and referral practices. Methods: This study will utilize a quasi-experimental design (pre-and post with a non-equivalent control group) to assess the impact of a five-day pilot oral health education program on the knowledge and referral practices of Nurses and Community Health Workers in primary health care centers in three states in Nigeria-(Lagos, Oyo, and Kano). The training modules were developed based on the six iterative steps described in the intervention mapping framework - needs assessment, highlighting program objectives and outcomes, selection of theory and mode of intervention, designing program based on theory, designing implementation plans, and developing an evaluation plan. Only the intervention group will participate in the full educational training sessions but both groups will complete the pre-and post-intervention questionnaires. Discussion: This pilot training combined the standardized training modules from the recently launched "Oral Health Training Course for Community Health Workers in Africa" and a newly developed maternal and child oral health module by our group using an evidence-based approach. To the best of our knowledge, this is the first program to examine the impact of the standardized OpenWHO modules. The success of this training will lay the foundation for developing a sustained channel for providing oral health education at the primary health care level in Nigeria, West Africa, and Africa.

Characterization of Typhoid Intestinal Perforation in Africa: Results From the Severe Typhoid Fever Surveillance in Africa Program.

Background: Typhoid intestinal perforation (TIP) remains the most serious complication of typhoid fever. In many countries, the diagnosis of TIP relies on intraoperative identification, as blood culture and pathology capacity remain limited. As a result, many cases of TIP may not be reported as typhoid. This study demonstrates the burden of TIP in sites in Burkina Faso, Democratic Republic of Congo (DRC), Ethiopia, Ghana, Madagascar, and Nigeria. Methods: Patients with clinical suspicion of nontraumatic intestinal perforation were enrolled and demographic details, clinical findings, surgical records, blood cultures, tissue biopsies, and peritoneal fluid were collected. Participants were then classified as having confirmed TIP, probable TIP, possible TIP, or clinical intestinal perforation based on surgical descriptions and cultures. Results: A total of 608 participants were investigated for nontraumatic intestinal perforation; 214 (35%) participants had surgically-confirmed TIP and 33 participants (5%) had culture-confirmed typhoid. The overall proportion of blood or surgical site Salmonella enterica subspecies enterica serovar Typhi positivity in surgically verified TIP cases was 10.3%. TIP was high in children aged 5-14 years in DRC, Ghana, and Nigeria. We provide evidence for correlation between monthly case counts of S. Typhi and the occurrence of intestinal perforation. Conclusions: Low S. Typhi culture positivity rates, as well as a lack of blood and tissue culture capability in many regions where typhoid remains endemic, significantly underestimate the true burden of typhoid fever. The occurrence of TIP may indicate underlying typhoid burden, particularly in countries with limited culture capability.

Colostomy closure: how to avoid complications.

PURPOSE: Colostomy is an operation frequently performed in pediatric surgery. Despite its benefits, it can produce significant morbidity. In a previous publication we presented our experience with the errors and complications that occurred during cases of colostomy creation. We now have focused in the morbidity related to the colostomy closure. The technical details that might have contributed to the minimal morbidity we experienced are described. METHODS: The medical records of 649 patients who underwent colostomy closure over a 28-year period were retrospectively reviewed looking for complications following these procedures. Our perioperative protocol for colostomy closure consisted in: clear fluids by mouth and repeated proximal stoma irrigations 24 h prior to the operation. Administration of IV antibiotics during anesthesia induction and continued for 48 h. Meticulous surgical technique that included: packing of the proximal stoma, plastic drape to immobilize the surgical field, careful hemostasis, emphasis in avoiding contamination, cleaning the edge of the stomas to allow a good 2-layer, end-to-end anastomosis with separated long-term absorbable sutures, generous irrigation of the peritoneal cavity and subsequent layers with saline solution, closure by layers to avoid dead space, and avoidance of hematomas. No drains and no nasogastric tubes were used. Oral fluids were started the day after surgery and patients were discharged 48-72 h after the operation. RESULTS: The original diagnoses of the patients were: anorectal malformation (583), Hirschsprung's disease (53), and others (13). 10 patients (1.5%) had complications: 6 had intestinal obstruction (5 due to small bowel adhesions, 1 had temporary delay of the function of the anastomosis due to a severe size discrepancy between proximal and distal stoma with a distal microcolon) and 4 incisional hernias. There were no anastomotic dehiscences or wound infection. There was no bleeding, no anastomotic stricture and no mortality. CONCLUSION: Based on this experience we believe that colostomy closure can be performed with minimal morbidity provided a meticulous technique is observed.

Clinical predictors and outcome of bowel resection in paediatric intussusception.

INTRODUCTION: Surgery remains the mainstay in treating intussusception in developing countries, with a correspondingly high bowel resection rate despite a shift to non-operative reduction in high-income countries. OBJECTIVE: To assess factors associated with bowel resection and the outcomes of resection in childhood intussusception. METHODS: A review of children with intussusception between January 2006 and December 2015 at the University College Hospital, Ibadan, Nigeria. The patients were categorized based on the need for bowel resection and analysis done using the SPSS version 23. RESULTS: 121 children were managed for intussusception during this period. 53 (43.8%) had bowel resection, 61 (50.4%) did not require resection and 7 (5.8%) were unknown. 40 (75.5%) of the resections were right hemi-colectomy. The presence of fever, abdominal pain, distension, rectal mass, age < 12 months, heart rate > 145/min and duration of symptoms > 2 days were associated with the need for bowel resection (p < 0.05). However, only age and abdominal pain independently predicted need for resection. Bowel resection was more associated with development of post-operative complications and prolonged hospital stay (p < 0.05). CONCLUSION: Infants presenting with abdominal pain and abdominal distension after two days of onset of symptoms were more likely to require bowel resection. Resection in intussusception significantly increased post-operative complications and length of hospital stay.

Prior thoracic surgery has a limited impact on the feasibility of consecutive thoracoscopy in children: a prospective study on 228 procedures.

BACKGROUND: This study aimed to determine the impact of prior thoracic surgery on consecutive ipsilateral thoracoscopic surgery in children. METHODS: We prospectively analyzed 228 thoracic procedures, which were performed in 190 children (99 male,91 female; mean age, 5.1 years; range, 1 day to 18 years) over a 7-year period (January 2000 to August 2007).Of these, 137 were thoracoscopies and 91 conventional operations. A panel of pediatric pulmonologists, anesthetists,and pediatric surgeons decided whether a thoracoscopy or a conventional approach was indicated. The endpoints were conversion rate, intraoperative events, and complications in subsequent thoracoscopies with regard to the type of prior thoracic surgery. In addition, the reasons for exclusion from thorascopy of those patients,who had a previous thoracic operation, should be identified. RESULTS: Thirty-two patients (14%) had prior ipsilateral thoracic surgery; 20 of these underwent thoracoscopy,12 after prior thoracotomy and 8 after prior thoracoscopy. The type of initial approach had no significant impact on the conversion rate of subsequent thoracoscopy (1/12 after thoracotomy vs. 0/8 after thoracoscopy; not significant). The conversion rate was not significantly different in patients with or without prior surgery (1/20 vs. 19/117; not significant). However, there was a higher number of reconstructive procedures in patients without prior surgery, which was reflected in conversions due to lack of overview (n 12), bleeding (n 3), tension during reconstruction of a diaphragmatic defect (n 2) and esophageal atresia (n 2), and intraoperative respiratory problems (n 1). Twelve patients with a prior operation underwent thoracotomy due to limited respiratory capacity (n 5), advanced tumor stage, prior sternotomy (n 6), and limited visibility, leading to conversion during initial thoracoscopy (n 1). CONCLUSIONS: Prior thoracic operation has, independent of the initial approach, a limited impact on the feasibility of ipsilateral consecutive thoracoscopic surgery in children. The feasibility of thoracoscopy after prior operation is excellent.

Overview of Anorectal Malformations in Africa.

Anorectal malformation is one of the most common structural congenital malformations treated by pediatric surgeons globally. The outcome of care is largely dependent on the spectrum, clinical features, associated malformations, expertise of the surgeons, and available perioperative facilities. Africa has a large burden of unmet surgical needs in children, and as in other low resource settings, local pediatric surgeons are faced with different and challenging clinical scenarios, hence, adopt various measures to enable children with surgically correctable congenital malformations to survive. There are increasing collaborations between local surgeons and experts in other continents, which often involves surgeons traveling to Africa on missions or well-structured partnerships. It is highly beneficial for the physician who is interested in global-surgery to understand the terrain in low resource settings and prepare for possible changes in management plan. This review highlights the epidemiology, clinical presentation, treatment, and outcome of care of children with anorectal malformations in Africa and provides options adopted by pediatric surgeons working with limited resources.

The Value of Ultrasonography in the Diagnosis of a Rare Congenital Dermoid Cyst of the Anterior Fontanelle in an Infant.

A dermoid cyst is a benign lesion that may occur in different parts of the body. A dermoid cyst of the subgaleal space over the anterior fontanelle is rather uncommon. We present a case of congenital dermoid cyst of the anterior fontanelle in a 3-month-old male infant, underscoring the value of ultrasonography in the diagnosis and highlighting the classical clinical, sonographic, surgical, and pathological findings.

Un kyste dermoïde est une lésion bénigne qui peut survenir dans différentes parties du corps. Un kyste dermoïde de l'espace sous-galéal au-dessus de la fontanelle antérieure est plutôt rare. Nous présentons un cas de kyste dermoïde congénital de la fontanelle antérieure chez un nourrisson de sexe masculin de 3 mois, soulignant l'intérêt de l'échographie dans le diagnostic et mettant en évidence les résultats cliniques, échographiques, chirurgicaux et pathologiques classiques.

Outcome of Management of Neonatal Intestinal Obstruction at a Tertiary Center in Nigeria.

BACKGROUND: Intestinal obstruction in a newborn remains a significant emergency in pediatric surgery. Clinical presentation is often subtle with sudden deterioration of their clinical states. Clinical outcome in the developing countries is poor owing to a variety of factors. OBJECTIVE: The objective of this study is to identify the factors affecting the management outcome in our environment. PATIENTS AND METHODS: Data on clinical presentation, management, and outcome of all neonates managed for intestinal obstruction over a 13-year period at a tertiary center in Nigeria were retrospectively reviewed. Analysis of factors affecting the management outcome was also performed. RESULTS: One hundred and seventeen neonates comprising 85 (72.7%) boys and 32 (27.3%) girls were managed for intestinal obstruction. The age at presentation ranged from 0 to 29 days, with a mean of 6.86 ± 8.4 days. Seventy-five (64.1%) patients presented within a week of onset of symptoms and 42 (35.9%) patients later. Eighty-five patients (72.6%) presented with symptoms from birth. The most common causes of intestinal obstruction included anorectal malformation in 62 (53%) neonates and Hirschsprung's disease in 16 (13.7%) neonates. Other causes included obstructed inguinoscrotal hernias, duodenal atresia, jejunoileal atresia, malrotation, and annular pancreas. Eleven patients died with a mortality rate of 9.4%. The age at presentation (P = 0.001) and the presence of postoperative complications (P = 0.009) were significantly related to the duration of hospital stay. Furthermore, the presence of postoperative complications (P = 0.012) was significantly associated with postoperative mortality. CONCLUSION: Early presentation and postoperative complications significantly affected the morbidity and mortality associated with the management of neonates with intestinal obstruction.

Use of a Heineke-Mikulicz like stricturoplasty for intractable skin level anal strictures following anoplasty in children with anorectal malformations.

INTRODUCTION: We introduced a modification of the Heineke-Mikulicz technique to treat intractable skin level anal strictures post posterior sagittal anorectoplasty (PSARP). The aim of this article is to describe the technique and outcome in a series of patients. METHODS: This was a retrospective evaluation of patients who had Heineke-Mikulicz like stricturoplasty performed for a post PSARP skin level stricture over a one-year period. RESULTS: Five patients who were operated using the technique were reviewed. All had severe anal strictures that could admit Hegar dilator sizes 6 to 9 at 16months to 5years after PSARP. All underwent routine dilatations, which became increasingly painful. As an alternative to continued dilatations, an operative procedure was offered. The surgery was done as a day case and lasted 10 to 30min. The anus at the end of the procedure could comfortably accept a Hegar dilator size 14 to 17. None of the patients had a colostomy after the procedure and there were no complications. CONCLUSIONS: The Heineke-Mikulicz like stricturoplasty is a simple surgical procedure that can be done in an ambulatory setting to treat children with intractable skin level anal stricture if this develops following definitive surgery for anorectal malformations.

Spectrum of colorectal surgery operations performed in a single paediatric surgery unit in sub-Saharan Africa.

BACKGROUND: Colorectal surgery is a budding subspecialty of paediatric surgery and typifies the advances in the management of surgical conditions in children. The colorectal burden in resource poor settings, though reported to be challenging, remains undocumented. The aim of the present study was to review the typical operative paediatric colorectal caseload in a single centre in sub-Saharan Africa. MATERIALS AND METHODS: A retrospective review of the operative records of the division was conducted between 2009 and 2013. Data were obtained on the demography, diagnosis, procedure performed and type of anaesthesia used; entered into a computer using SPSS (IBM Corp; Armonk, NY) and analysed. RESULTS: A total of 120 colorectal operations were performed in 90 patients with age ranging from 1 to 13 years. The major diagnoses were anorectal malformations (64.4%) and Hirschsprung disease (HD) (31.1%). The most often performed operations were colostomy (45.0%), posterior sagittal anorectoplasty (17.5%) and pull through (17.5%). The number of colorectal operations performed each year ranged from 12 in 2009 to 36 in 2012. A higher proportion of patients with anorectal malformations (46.6%) presented within the neonatal period compared with those with HD (17.9%), P = 0.005. The age at definitive surgery was less in patients with anorectal malformations compared to patients with HD (P = 0.003). CONCLUSIONS: Congenital malformations represent the bulk of the caseload in paediatric colorectal surgery in sub-Saharan Africa and patients typically present late; although patients with anorectal malformations present and are operated upon significantly earlier than those with HD.

Mothers' awareness of anorectal malformations: a pointer to delayed diagnosis in a developing country.

INTRODUCTION: Delay in the presentation of babies with anorectal malformations (ARMs) to the pediatric surgeon accounts for a major cause of morbidity and mortality in developing countries. In countries lacking proper guidelines for screening and newborn physical examination, a lot of responsibility is placed on parents and caregivers; with mothers often being the first to note abnormalities in their babies. The aim of the study was to assess the awareness of mothers about ARM and their knowledge about normal or abnormal appearance of the anus. MATERIALS AND METHODS: A descriptive cross-sectional study involving mothers attending immunization clinics at two hospitals in a developing country was conducted using a structured interviewer administered questionnaire. Data were obtained on sociodemographic characteristics, awareness of ARM, and knowledge of appearance of the anus by requesting mothers to identify if three pictures of the perineum were normal or abnormal. RESULTS: A total of 365 mothers participated in the study with age ranging from 17 to 42 years. Only 71 (19.5%) mothers had ever heard about ARM. A picture of a girl with ARM and rectoperineal fistula was correctly identified by 66 (18.1%) and that of a boy with ARM and rectoperineal fistula by 71 (19.5%) mothers. A higher proportion (25.0%) of the mothers who were older than 30 years were aware of ARM than those younger than 30 years (16.0%), (p = 0.035). Participants with tertiary education were more likely to be aware of ARM than those with 12th grade or less education (31.1 vs. 6.9%, p < 0.001). Skilled workers were also more likely to be aware of ARM than unskilled workers and artisans (41.1 vs. 8.1%, p < 0.001). The predominant technique of "checking" the anus by the mothers was "inspection of their baby's perineum." CONCLUSION: Level of awareness of ARMs was low among women interviewed. Educational intervention targeting young mothers from low socioeconomic class is suggested.

Laparoscopic-assisted Malone appendicostomy in the management of fecal incontinence in children.

INTRODUCTION: The antegrade continence enema procedure offers convenient enema administration for patients with fecal incontinence and can be performed by a minimally invasive approach that provides shorter hospital stay, less analgesia requirement, and better cosmesis. We present our experience using this approach for fecal incontinence patients and technical modifications to reduce complications. METHODS: Following successful management of fecal incontinence through bowel management using a daily rectal enema, 44 patients underwent a laparoscopic-assisted Malone appendicostomy procedure. We reviewed the diagnosis underlying the fecal incontinence, operative technique, duration of surgery, length of hospital stay, and postoperative complications. RESULTS: The mean age at surgery was 8.6 ± 1.0 years. The diagnoses included anorectal malformations (31), idiopathic constipation (6), Hirschsprung disease (3), and others (4). All the patients underwent a V-V umbilico-appendicoplasty. The cecum was plicated around the base of the appendix in 34 patients (77%); this step was omitted in 10 (23%). The median follow-up was 21 months (range: 3-51 months). Twelve complications were recorded in 9 patients (20.5%)--leakage from the stoma in 1 (2.3%), stomal stenosis in 5 (11.4%), and a combination of both in 3 (6.8%)--with an overall stricture rate of 18.2% (8/44) and leakage rate of 9.1% (4/44). Strictures were managed with minor operative revision. Plicating the cecum was associated with a lower leakage rate compared with the nonplicated group (0/34, 0% versus 4/10, 40%; P = .002). All patients were consistently clean between enemas following their antegrade continence enema procedure. CONCLUSIONS: The umbilical appendicostomy provides a convenient and cosmetic location for enema administration. Cecal plication, which is feasible using a laparoscopic-assisted approach, significantly reduces the leakage rate. Stomal stenoses remains a problem, may be lessened by a V-to-V umbilical to appendix anastomosis, and are easily fixed with a revision.

Management of H-type rectovestibular and rectovaginal fistulas.

INTRODUCTION: H-type rectovestibular or rectovaginal fistulas are rare entities in the spectrum of anorectal malformations seen in North America. Management options described in the literature have included perineal repair, anterior perineal anorectoplasty, vestibuloanal pull-through, and limited or formal posterior sagittal anorectoplasty, with a reported recurrence rate of 5% to 30%. We describe our approach and outcome in the management of these patients. METHODS: In a series of 1170 females with anorectal malformation, we cared for 8 patients who had an H-type rectovestibular or rectovaginal fistula and reviewed their clinical presentation, diagnosis, operative technique, and postoperative course. RESULTS: The patients' presenting symptoms included passage of stool per vagina (6), constipation (3), labial abscess (1), and recurrent urinary tract infection (1). There was associated anorectal stenosis in 3 patients. The remaining 5 patients had normal anal openings. Endoscopy was not helpful in locating the fistulas, but the fistulas were all demonstrated on direct inspection under anesthesia. The fistula was located in the vestibule (4), vagina (3), or labia (1). One patient had an associated presacral mass. Two patients had been operated on twice previously using a perineal repair and a protective colostomy and presented with third recurrences. In 5 cases, a posterior sagittal approach was used, placing sutures circumferentially around the fistulous opening on the rectal side, ligating the fistula, and pulling down a normal segment of rectum to be placed in front of the repaired vaginal wall. In our last 3 cases, we performed a transanal mobilization of the anterior rectal wall, leaving the perineal body intact. After our repairs, the patients have been followed up for 3 months to 15 years with a median of 15 months, and we have seen no recurrences. CONCLUSIONS: In addition to vaginal passage of stool, an H-type fistula should be suspected when there is a labial abscess in an infant, and an associated anal stenosis or presacral mass must be checked for. Direct inspection is the key, with a careful look in the vestibule, because endoscopy may miss the fistula. The essential technical point for repair is to get healthy anterior rectal wall to cover the area of fistula on the posterior vagina. A transanal approach, leaving the perineal body intact, is an excellent option for this repair.

Acquired posterior urethral diverticulum following surgery for anorectal malformations.

PURPOSE: Despite significant advances in the surgical management of anorectal malformations (ARMs), many children still experience significant debilities from potentially avoidable complications. One complication, the posterior urethral diverticulum, may have untoward consequences if not recognized and treated. METHODS: A retrospective cohort review was undertaken of male patients who presented to us with persistent problems after being operated on elsewhere for ARM. Twenty-nine patients presented with a urethral diverticulum. Their charts were reviewed for the type of malformation, prior repair, presentation, treatment, and postoperative follow-up. RESULTS: Twenty-nine patients were identified that fit the criteria for this study. To date, 28 patients have been managed with reoperation. Urinary complaints were the most common presenting symptoms. All patients were repaired using a posterior sagittal approach. Pathology of the diverticulum in one patient revealed a well-differentiated mucinous adenocarcinoma. CONCLUSION: The incidence of acquired posterior urethral diverticulum has decreased with the popularization of the posterior sagittal incision. There is a theoretical concern that the incidence may increase with the use of laparoscopy for the treatment of ARMs especially those where the fistula is below the peritoneal reflection. Once detected, the diverticulum should be excised.

Redo pull-through in Hirschsprung's [corrected] disease for obstructive symptoms due to residual aganglionosis and transition zone bowel.

BACKGROUND: Reoperations in Hirschsprung disease may be required for residual aganglionosis or transition-zone bowel found at the distal pull-through. We aimed to review the management of patients who had this complication and offer suggestions on how to avoid it. METHODS: Ninety-three patients with Hirschsprung disease were referred to our institution with recurrent problems after a pull-through done elsewhere. All required reoperations with a variety of indications, and of these, 25 had residual aganglionosis/transition-zone histology. This was the only indication for redo in 16 children. RESULTS: Children (range, 2-17 years) presented 6 to 66 months after the initial pull-through. The predominant symptoms were enterocolitis (n = 9 [56%]), constipation (n = 7 [44%]), failure to thrive (n = 5 [31%]), and impaction (n = 4 [25%]). The rectal biopsy performed as part of their post pull-through work up showed hypertrophic nerves (n = 16), absent ganglion cells (n = 6), and normal ganglion cells (n = 10). The original frozen-section biopsy, determining the level of the pull-through, only sampled the seromuscular layer in 3 children, leading to misdiagnosis. Reoperations involved a transanal resection (n = 15) and a posterior sagittal approach (n = 1). In all cases, obstructive symptoms were resolved, and no patient has had recurrent enterocolitis. CONCLUSION: Patients' post pull-through with recurrent obstructive symptoms may have residual aganglionosis or transition-zone bowel. Reoperation can result in the resolution of these symptoms. A full-thickness biopsy at the time of the initial pull-through to include the mucosa and submucosa may increase the possibility of identifying hypertrophic nerves.

The utility of routine pouchogram before ileostomy reversal in children and adolescents following ileal pouch anal anastomosis.

INTRODUCTION: Pouchograms are used to assess the integrity of the ileal pouch anal anastomosis (IPAA) in patients who have undergone restorative proctocolectomy. Its benefits have been questioned, and there are no data to support the routine use in children. METHODS: We retrospectively reviewed the charts of 26 patients who had an IPAA and pouchogram at our institution between 2001 and 2009. Each patient also underwent an examination under anesthesia to assess the integrity of the IPAA on the day of the ileostomy closure. RESULTS: The mean age of the patients was 13.8 (± 0.7) years. The pouchogram was performed at a median of 6 weeks after the IPAA (range, 4-20 weeks). The findings were normal in 26 (89.7%) and demonstrated stricture in 2 (6.9%) and leak in 1 (3.4%). History was suggestive and physical examination was confirmatory in these 3 problematic cases. CONCLUSIONS: A contrast enema is not routinely required to evaluate the integrity of the IPAA before ileostomy reversal in pediatric patients. Complications can be detected by history and rectal examination before ileostomy closure. We recommend the use of contrast enema only in symptomatic patients where a leak is suspected, thereby limiting radiation exposure and inconvenience.
