Cecal volvulus: a report of two cases occurring after the antegrade colonic enema procedure

Internal hernia with volvulus after major abdominal reconstructions in pediatric urology - An infrequently reported and potentially devastating complication

INTRODUCTION

Enterocystoplasty (EC), appendico- or ileovesicostomy (APV), and appendicocecostomy (APC) can facilitate continence and prevent renal damage for patients with congenital urologic or bowel disease. Bowel obstruction is a well-documented complication of these procedures, and the etiology of obstruction is variable. The aim of this study is to determine the incidence and describe the presentation, surgical findings, and outcomes of bowel obstruction from internal herniation due to these reconstructions.

METHODS

In this single institution retrospective cohort study patients who underwent EC, APV, and/or an APC between 1/2011 and 4/2022 were identified via CPT codes within the institutional billing database. Records for any subsequent exploratory laparotomy during this same timeframe were reviewed. The primary outcome was an internal hernia of bowel into the potential space between the reconstruction and the posterior or anterior abdominal wall.

RESULTS

Two hundred fifty seven index procedures were performed in 139 patients. These patients were followed for a median of 60 months (IQR 35-104 months). Nineteen patients underwent a subsequent exploratory laparotomy. The primary outcome occurred in 4 patients (including one patient who received their index procedure elsewhere) for a complication rate of 1% (3/257). The complications occurred between 19 months and 9 years after their index procedure (median 5 years). Patients presented with bowel obstruction; two patients also had sudden pain following an ACE flush. One complication was caused by small bowel and cecum passing around the APC and subsequently volvulizing. A second was caused by bowel herniating behind the EC's mesentery and the posterior abdominal wall. A third was caused by bowel herniating behind the APV mesentery and subsequently volvulizing. The exact etiology of fourth internal herniation is unknown. Of the three surviving patients, all required resection of ischemic bowel and 2 required resection of the involved reconstruction. One patient died intraoperatively from cardiac arrest. Only 1 patient required a subsequent procedure to regain lost function.

CONCLUSION

Internal herniation caused by small or large bowel passing through a defect between the mesentery and abdominal wall or twisting around a channel occurred in 1% of 257 reconstructions performed over 11 years. This complication can arise many years after abdominal reconstruction, resulting in bowel resection and possibly takedown of the reconstruction. When anatomically possible and technically feasible, the surgeon should close any potential spaces created during the initial abdominal reconstruction.

A Rare Case of Cecal Bascule in a Child With Normal Neurodevelopment

Cecal volvulus is a rare cause of bowel obstruction in adults and an extremely rare presentation in children. One form known as a cecal bascule has only previously been reported in children with neurodevelopmental issues or with severe chronic constipation. We present the case of a 10-year-old boy who presented with an acute history of left lower quadrant abdominal pain, who upon investigation was found to have a cecal bascule.

Long-term outcomes of antegrade continence enema in children with chronic encopresis and incontinence: what is the optimal flush to use?

PURPOSE

Severe constipation and encopresis are significant problems in the pediatric population. Medical management succeeds in 50-70%; however, surgical considerations are necessary for the remainder such as the antegrade continence enema (ACE). The purpose of this study is to assess the long-term outcomes following the ACE procedure.

METHODS

All patients undergoing an ACE over a 14-year period were included. Data on clinical conditions, treatments, and outcomes were collected. A successful outcome was defined as remaining clean with ≤ 1 accident per week. Comparative data were analyzed using the Fisher's exact test, Mann-Whitney U test, or Student's t test.

RESULTS

There were 42 ACE patients, and overall, 79% had improvement in their bowel regimens. Encopresis rates decreased from 79 to 5% (P < 0.001). Admissions for cleanouts decreased from 52 to 19% (P = 0.003). All cases of Hirschsprung's, functional constipation and spina bifida were successful. Rates of success varied for other diseases such as slow-transit constipation (60%) and cerebral palsy (33%). A majority (85%) required a change in the enema composition for improvement.

CONCLUSION

In our study, ACE reduced soiling, constipation, and need for fecal disimpaction. Higher volume saline flushes used once a day was the optimal solution and most preferred option.

A systematic review of the management and outcomes of cecal and appendiceal volvulus in children

AIM

Appendiceal volvulus (AV) and cecal volvulus (CV) are rare conditions and there is no consensus regarding the best surgical approach. This study reviewed CV and AV management and outcomes in children.

METHODS

PubMed was reviewed from 1990 to 2018 for AV and CV in children and studies published in English were selected by two independent reviewers. This identified 24 papers that provided case reports on 29 children (72% male) with a median age of 10 years.

RESULTS

Abdominal distension and abdominal pain were the most common symptoms and seven children had Cornelia de Lange syndrome. The initial treatment was surgical in 27 cases and endoscopic in 2. In 23 children, variants of cecopexy were performed. There was no mortality. Complications occurred in seven cases: five with sepsis and two with enterocutaneous fistulas. There were three CV recurrences and these were all in cases where cecopexy was not performed.

CONCLUSION

AV and CV are rare paediatric pathologies. Since a quarter of the patients had Cornelia de Lange syndrome, it is paramount to consider CV when abdominal symptoms occur. Complications were minor with prompt management. In order to reduce recurrence, cecopexy is recommended in CV cases and appendectomy in AV cases.

Rare case of pediatric cecal volvulus

An 11-year-old female child presented with abdominal pain, vomiting and constipation. An exploratory laparotomy revealed a cecal volvulus due to a congenital band and malfixation of the cecum. This was treated by excision of the band, derotation and decompression of cecum though an appendiceal stump suction.

Malone antegrade continence enema (MACE) for fecal incontinence in imperforate anus improves quality of life

The MACE procedure has been used in patients with imperforate anus (IA) to improve fecal continence. Our aim was to assess the impact of the MACE on the quality of life (QOL) in children with IA and fecal incontinence. A retrospective review was performed of children with IA that underwent the MACE procedure between 1997 and 2004. Patients and their parents were contacted by telephone survey regarding continence and its psychosocial effects before and after MACE. The same survey was given to the patients' teachers. Responses to 15 questions were compiled and a QOL score calculated and significance evaluated by t-test (P < or = 0.05). IRB approval was obtained. Thirty-two patients were identified with a mean age at operation of 9 years (4-19 years) and mean follow-up of 3.8 years (7 months to 8 years). Four patients had a low malformation, 8 were intermediate, 15 were high, and 5 had a cloacal anomaly. Twenty patients had documented sacral/spinal anomalies, including five with tethered cord. Post-MACE complications included stenosis in 16 (50%), with 11 requiring an operative revision at a mean of 21.7 months (2 months to 6 years), takedown in one at 4 years and volvulus in one at 18 months. Prior to the MACE, 18/25 (72%) had poor QOL scores. Post-MACE QOL results were similar between patients, parents and teachers. Patients' mean QOL score improved from 59.9 to 26.3% (P < 0.001), with parents from 59.7 to 26.4% (P < 0.001). QOL score improved >50% in nine families, 25-50% in ten and <25% in six. All patients and parents interviewed reported an improvement in their QOL following the MACE. This procedure should be offered to children with IA with the expectation of significant improvement in QOL.
