Imperforate Anus Course

Lesson 1 • Anorectal Physiology and Continence

Explains resting tone, voluntary squeeze, rectoanal inhibitory reflex, and sensory mechanisms. Links normal physiology to functional deficits seen in malformations.

Lesson 2 • Associated Spinal and Sacral Anatomy

Reviews sacral segmental innervation and sacral ratio measurement. Connects sacral anomalies to predicted continence outcomes in malformation patients.

Lesson 3 • Embryological Development of the Hindgut

Covers cloacal partitioning, urorectal septum formation, and critical developmental windows. Establishes the embryological basis for understanding malformation subtypes.

Lesson 1 • Historical Classification Systems

Traces the evolution from Wingspread to Krickenbeck classifications. Contextualises current terminology within its historical development.

Lesson 2 • High and Intermediate Malformations in Males

Covers rectobulbar, rectoprostatic, and rectovesical fistulas with their anatomical relationships. Distinguishes lesion levels to determine operative approach.

Lesson 3 • Low Malformations in Males

Defines perineal fistula, anal stenosis, and covered anus in male patients. Identifies anatomical landmarks distinguishing low from intermediate lesions.

Lesson 4 • Rare and Complex Variants

Addresses rectal atresia, stenosis, and complex syndromic associations. Prepares clinicians to recognise atypical presentations beyond standard categories.

Lesson 1 • Imaging Modalities and Indications

Reviews invertogram, cross-table lateral X-ray, ultrasound, and MRI roles. Matches imaging choice to clinical scenario and lesion complexity.

Lesson 2 • Newborn Clinical Assessment

Covers perineal inspection, fistula identification, and meconium passage evaluation. Establishes the clinical examination as the first diagnostic step.

Lesson 3 • Screening for Associated Anomalies

Applies the VACTERL association framework to guide systematic screening. Ensures no life-threatening associated defect is missed before surgery.

Lesson 4 • Preoperative Workup for Definitive Repair

Outlines distal colostogram technique, urological evaluation, and anaesthesia assessment. Ensures complete anatomical mapping before definitive surgical correction.

Lesson 1 • Laparoscopic-Assisted Repair

Introduces laparoscopic-assisted anorectal pull-through for high lesions. Compares laparoscopic and open approaches regarding visualisation and outcomes.

Lesson 2 • Colostomy Closure Principles

Defines timing, technique, and bowel preparation for colostomy closure after definitive repair. Ensures safe restoration of intestinal continuity.

Lesson 3 • Perineal Fistula Repair Technique

Details minimal PSARP and cutback anoplasty for low lesions. Applies limited dissection principles to preserve existing sphincter function.

Lesson 4 • Principles of Posterior Sagittal Anorectoplasty

Establishes the PSARP philosophy: muscle complex identification, fistula division, and neo-anus placement. Frames all subsequent operative technique sections.

Lesson 1 • Urological Outcomes in Cloaca

Reviews bladder dysfunction, vesicoureteral reflux, and renal preservation strategies. Links operative decisions to long-term urological function.

Lesson 2 • Complex Cloacal Repair Strategies

Addresses long common channel repair, vaginal replacement, and urinary diversion options. Prepares surgeons for the most challenging cloacal variants.

Lesson 3 • Anatomy and Classification of Cloaca

Defines common channel length, urogenital sinus anatomy, and Müllerian anomaly variants. Establishes the anatomical framework for operative planning.

Lesson 4 • Total Urogenital Mobilisation

Details TUM technique for short common channel cloaca repair. Explains en-bloc mobilisation to achieve urethral and vaginal separation.

Lesson 1 • Urological Complication Management

Covers urethral injury, urinary fistula, and neurogenic bladder after repair. Integrates urological follow-up into the standard postoperative pathway.

Lesson 2 • Anal Dilation Programme

Defines the Hegar dilator protocol, sizing progression, and caregiver training for home dilation. Prevents anastomotic stricture as the most common early complication.

Lesson 3 • Early Surgical Complications

Identifies wound dehiscence, anastomotic stricture, fistula recurrence, and mucosal prolapse. Provides management algorithms for each complication type.

Lesson 4 • Immediate Postoperative Management

Covers wound care, urinary catheter management, and pain control in the early postoperative period. Establishes the standard of care for the first 72 hours.

Lesson 1 • Antegrade Continence Enema Procedures

Covers Malone appendicostomy and cecostomy button techniques for antegrade washout. Selects candidates based on failed retrograde management.

Lesson 2 • Biofeedback and Pelvic Floor Therapy

Applies biofeedback training and pelvic floor exercises to patients with voluntary muscle potential. Integrates therapy into a comprehensive continence programme.

Lesson 3 • Predicting Continence Potential

Uses malformation type, sacral ratio, and spinal anatomy to stratify continence prognosis. Guides realistic goal-setting for patients and families.

Lesson 4 • Enema-Based Bowel Management

Details phosphate, saline, and glycerin enema protocols for constipation-dominant patients. Provides step-by-step administration technique for caregivers.

Lesson 1 • Psychosocial and Quality-of-Life Outcomes

Evaluates body image, social continence, school participation, and mental health in patients. Connects functional outcomes to overall quality-of-life measurement.

Lesson 2 • Urological Long-Term Follow-Up

Monitors renal function, bladder capacity, and urinary continence over time. Identifies patients requiring urological intervention before irreversible damage occurs.

Lesson 3 • Gynaecological Outcomes in Females

Addresses vaginal stenosis, menstrual function, and fertility outcomes in female patients. Integrates gynaecological surveillance into routine long-term follow-up.

Lesson 4 • Transition to Adult Care

Designs structured transition protocols from paediatric to adult surgical and medical services. Ensures continuity of bowel management, urological, and gynaecological care.
