Rectal prolapse: Do we really have a perfect surgical solution? pptx copyDr Amit Dangi
Ventral rectopexy has gained worldwide acceptance for surgical correction of rectal prolapse and high-grade internal rectal intussusception. The technique is based on correcting the descent of the posterior and middle compartments combined with reinforcement of the vaginal septum and elevation of the pelvic floor. anterior mobilization of the distal rectum and mesh suspension performed during VR can correct full-thickness rectal prolapse, rectoceles, and internal rec- tal prolapse and can be combined with vaginal prolapse procedures, such as sacrocolpopexy, in patients with multicompartment pelvic floor defects.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
2. Introduction
The exstrophy-epispadias complex (EEC) is a rare spectrum of defects
of genitourinary and gastrointestinal tracts, musculoskeletal system,
pelvic floor musculature, and bony pelvis.
The three most common presentations of EEC:
1. Epispadias
2. Classic bladder exstrophy (CBE)
3. Cloacal exstrophy (CE)
3. ▪ Complete epispadias is the least severe form of EEC and presents
with a dorsally open urethral meatus with mild pubic diastasis and
a closed anterior abdominal wall and bladder.
▪ CBE, the most common presentation of EEC, presents with a wide
pubic diastasis and an abdominal wall defect exposing an open
bladder and urethra with an epispadiac opening.
4. ▪ CE, the most severe of the three presentations, is similar, but a
portion of cecum or hindgut separates the two open hemi
bladders.
▪ CE with malformations of the gastrointestinal, musculoskeletal,
and central nervous systems, also known as the OEIS
(omphalocele, exstrophy, imperforate anus, and spinal
abnormalities) complex.
6. Epidemiology
▪ Complete Epispadias: It occurs in one in every 117,000 male births,
and only one of every 484,000 female births.
▪ CBE: one per 10,000 to 50,000 births and affecting males twice as
often as females.
▪ CE: one in 200,000 births,
7. Risk factors of EEC
▪ Caucasian race
▪ young maternal age and maternal multiparity.
▪ children conceived with assisted-reproductive technologies such as
in vitro fertilization
8. Etiopathogenesis
▪ The cause of EEC is not completely understood
▪ Theory of a disorder of cloacal membrane development.
▪ During the fourth gestational week, the cloacal membrane may overdevelop,
preventing mesenchymal migration between the ectoderm and endoderm.
▪ That inhibits normal development of the lower abdominal musculature and
pelvic bones
▪ it makes the cloacal membrane unstable and prone to early rupture.
▪ The timing and location of rupture of the cloacal membrane dictate the
patient’s presentation along the exstrophy-epispadias spectrum
9. Etiopathogenesis
▪ Epispadias occurs if the rupture produces a division or nonunion at the distal
end of the urinary tract.
▪ CBE results if the rupture occurs after the urorectal septum divides the
gastrointestinal from the genitourinary tracts
▪ CE results if the rupture occurs before this separation.
10. Division of the human cloaca
(a) 3.5 mm stage; (b) 4 mm stage; (c) 8 mm stage; (d) 1 mm stage. The asterisks
in (a), (b) and (d) indicate the cloacal septum.
11. ▪ failure of one or both of the lateral body wall folds to move far
enough ventrally to meet its counterpart in the midline.
▪ Abnormal development of the genital hillocks caudal to the normal
position.
▪ There may be involvement of the allantois in the development of
cloacal exstrophy.
▪ lack of “rotation” of the pelvic ring primordium prevents structures
attached to the pelvic ring from joining in the midline, allowing
herniation of the bladder to occur
12. Etiopathogenesis (molecular and genetic)
▪ p63 is a member of the p53 tumor suppressor family that is highly
expressed in stratified epithelium including the bladder and its
overlying skin. Its expression is decreased in CBE patients.
▪ These results led to the recent finding that insertion and deletion
polymorphisms of ΔNp63 lead to the reduced p63 expression that
may cause EEC.
14. Urogenital Anomalies
▪ the bladder is normal in epispadias, it is exposed anteriorly through the
abdominal wall in both CBE and CE.
▪ In most cases the bladder and abdominal wall should be closed soon after birth.
▪ if the bladder template is too small (<3 cm), is covered with polyps, or appears
inelastic, primary closure should be delayed.
▪ Histologically, the exstrophic bladder appears immature, with fewer myelinated
nerves;
▪ there is potential for normal development after a successful initial closure.
▪ If the bladder capacity does not increase sufficiently following closure,
augmentation cystoplasty may be needed
15. Urogenital Anomalies
▪ when the bladder is excessively fibrotic or is too small orthotopic neobladder
or a continent catheterizable pouch may be needed.
▪ The ureters in CBE and CE patients enter the bladder at an abnormal angle
leading to vesicoureteral reflux (VUR) in all patients following bladder closure.
▪ If VUR does not lead to upper urinary tract changes, the ureters are
reimplanted into the bladder at the time of augmentation or bladder neck
reconstruction in staged repair.
▪ Common anomalies include ureteropelvic junction obstruction, horseshoe
kidney, and ectopic kidney
16. Urogenital Anomalies
▪ Males have a urethral meatus located dorsally between the penopubic angle
and the proximal glans. Distal to its ectopic opening, the urethra is open
dorsally creating a spade-like appearance.
▪ the phallus is also shorter and broader often with significant dorsal chordee.
▪ Contributing to this foreshortened appearance is the lateral displacement of
the corporal bodies under the pubic bones.
▪ In CE, the phallus is typically split completely between the diastatic pubis,
with each half often of unequal size.
17. Urogenital Anomalies
▪ In EEC females, the distal aspect of the dorsal urethra remains open, resulting
in a patulous bladder neck.
▪ The mons pubis is flattened and displaced laterally while the vagina and
introitus are displaced anteriorly.
▪ The bifid clitoris is usually located in the anterior vaginal wall which is
surrounded by divergent labia.
▪ The vagina is often short or stenotic.
▪ Mullerian anomalies are common in female CE patients and include vaginal or
uterine duplication or sometimes complete agenesis.
18. Musculoskeletal Anomalies
▪ the anterior abdominal wall is intact in epispadias,
▪ CBE and CE, the bladder and urethra are exposed through a triangular defect
in the lower abdominal wall.
▪ The opening extends from the umbilicus to the intrasymphyseal band
inferiorly.
▪ Umbilical hernias are common but are usually insignificant
▪ Indirect inguinal hernias, due to a persistent processus vaginalis, large inguinal
rings, and the relatively straight direction of the inguinal.
▪ hernias easily repaired
19. Musculoskeletal Anomalies
▪ Patients with EEC often demonstrate diastasis of their pubic rami with
divergent distal rectus abdominis muscles.
▪ CBE patients have a mean pubic diastasis of 4.8 cm, external rotation of both
the anterior and posterior segments of the pelvis, 30% shortening of the
anterior pelvis, increased distance between the triradiate cartilage, and
retroversion of the acetabulum.
▪ These patients also have wider sacroiliac joint angles, a more inferiorly rotated
pelvis, and a larger sacrum.
▪ In CE , more malrotation and asymmetry than in CBE pelves.
▪ pelvic deformities cause a waddling gait.
20. The anatomy of the
normal bony pelvis is seen
in transverse view.
Superimposed are the
deviations observed in the
pelvis of classic bladder
exstrophy patients.
In the posterior
segment, each half is
externally rotated 12°.
The acetabulae are
retroverted, yielding an
increased intertriradiate
distance. In the anterior
segment, each half is
externally rotated 18 °
and is on average 30%
shorter.
21. Musculoskeletal Anomalies
▪ the levator ani in CBE patients has a
larger mean area, is located more
posteriorly to the rectum, and is
externally rotated and flattened resulting
in a “boxlike, open book” pelvis with an
anteriorly positioned bladder.
▪ The obturator internus and externus are
outwardly rotated.
▪ These lead to incontinence and females
uterine prolapse.

23. Gastrointestinal Abnormalities
▪ CBE and CE have an anteriorly displaced anus and anal sphincter. predisposes
exstrophy patients to fecal incontinence.
▪ CBE patients occasionally have omphalocele, imperforate anus, rectal
stenosis, and rectal prolapse.
▪ CE patients always have:
1) omphalocele,
2) imperforate anus,
3) rudimentary hindgut,
4) malrotation of the bowel,
5) short gut syndrome,
24. Neurospinal Abnormalities
▪ 7% of CBE patients will have a spinal abnormality such as spina bifida occulta,
scoliosis, and hemivertebrae. Most of the abnormalities are uncomplicated,
but spinal dysraphism may cause neurologic dysfunction.
▪ Nearly all CE patients demonstrate significant neurospinal deficits including
neural tube defects, vertebral anomalies, spinal myelodysplasia, spinal
dysraphism, and tethered cord.
▪ These necessitate neurological evaluation with spinal US and MRI
▪ These exacerbate urinary and bowel incontinence, lower extremity
immobility, and erectile dysfunction.
25. Diagnosis
▪ The majority of EEC cases are first noted on postnatal exam.
▪ CBE and CE can be diagnosed prenatally with fetal transabdominal ultrasound
(US) between the 15th and 32nd weeks of pregnancy :
1.absence of bladder filling,
2.a low-set umbilicus,
3.widened pubic rami,
4.small genitalia, a lower abdominal mass that increases throughout the
duration of pregnancy
5.the prolapsed ileum in CE patients may look like an “elephant trunk”
26. Evaluation and Management at Birth
▪ In the delivery room the umbilical cord
should be tied with 2-0 silk close to the
abdominal wall so that the umbilical
clamp does not traumatize the delicate
mucosa and cause excoriation of the
bladder surface
▪ The bladder can then be covered with a
nonadherent film of plastic wrap to
prevent sticking of the bladder mucosa
to clothing or diapers
27. Goals of reconstruction of EEC
PRINCIPAL OBJECTIVES
▪urinary continence
▪volitional voiding
▪low-pressure urine storage
▪preservation of kidney function
▪functionally and cosmetically
acceptable external genitalia.
SECONDARY OBJECTIVES
▪avoid urinary tract infections (UTIs)
▪reduce risk of urinary calculi
▪minimize the risk for malignancy
associated with the urinary tract
▪integrity of the abdominal wall fascia
▪integrity of the pelvic floor.
28. Male Epispadias Repair
▪ Epispadias repair includes correction of dorsal chordee, glanular and urethral
reconstruction, and closure of penile skin.
▪ The modern modified Cantwell-Ransley repair advances the urethral meatus
to an orthotopic position utilizing a reverse meatal advancement and
glanuloplasty technique.
▪ The dorsal chordee is released by mobilizing the urethral plate from the
underlying corpora from the level of glans down to the prostatic urethra.
▪ The corporal bodies are anastomosed at the dorsal medial aspect over the
tubularized urethra.
▪ Older patients may have persistent chordee, in which case a cavernostomy
may be required.
29. Cantwell–Ransley repair for epispadias.
(a) The tubularized urethral plate is placed in a dorsal groove incision in the glans
penis. The dotted lines indicate the site of incision for the cavernosa –
cavernosotomies; (b) approximation of the corpora cavernosa and performance of
cavernosal anastomosis; (c) glans closure over urethra and skin closure.
30. complete penile disassembly
▪ Mitchell and Bagli have described a further modification of Cantwell-Ransley
repair in which the urethral plate and each corporeal body along with its
hemiglans are dissected completely free from each other.
▪ The urethra is then tubularized and placed into an anatomic, ventral position.
▪ This “complete penile disassembly” performed at the time of primary bladder
closure, the combination of which is called “complete primary repair of
bladder exstrophy” (CPRE)
▪ When performed as part of CPRE, it requires more extensive proximal
mobilization in order to place the bladder deeply into the pelvis
31. Complete penile disassembly technique (Mitchell and Bagli)
✓ Lines of initial dissection circumscribing the urethral
plate and bladder neck.
✓ dissection of the urethra from the underlying
corporeal bodies.
✓ Dotted line indicates the site of distal incision to
free the urethra entirely from the glans
✓ Corporeal bodies and two hemiglans are separated
by a longitudinal midline incision
✓ The urethra is tubularized and brought to the
ventrum.
✓ The corpora are reapproximated dorsally. They will
rotate medially when adequately dissected from
each other
32. ▪ Following epispadias repair, patients receive yearly gravity cystograms to
measure bladder capacity.
▪ When the patient desires continence (typically 5 to 9 years of age), he will
undergo a continence procedure, such as a Young-Dees- Leadbetter bladder
neck reconstruction (BNR), if the bladder capacity is sufficient.
▪ If the bladder template is too small, the patient will instead undergo a
combination of a bladder neck transection, bladder augmentation, and
continent urinary diversion.
▪ Female Epispadias Repair :Due to the comparatively shorter urethra, repair
of isolated female epispadias is generally done along with BNR, monsplasty,
and clitoroplasty
33. Classic Bladder Exstrophy Repair
▪ Repair of bladder exstrophy begins with closure of the bladder and abdominal
wall by either:
A. The modern staged repair of exstrophy (MSRE)
B. Complete primary repair for exstrophy (CPRE)
▪ There is a debate over the timing of the primary closure with proponents of
early bladder closure (closure during the first 72 hours of life) arguing that
prompt closure allows for earlier bladder cycling, improved bladder
expansion, and decreased risk of precancerous changes.
▪ Those delaying bladder closure state that it does not cause metaplastic
changes, can allow for concomitant epispadias repair, and increases the
likelihood of postclosure bladder growth in the case of a smaller template
34. Classic Bladder Exstrophy Repair
▪ Pelvic osteotomies may be performed at the time of primary closure in order
to deepen their flattened pelvis, close the pubic diastasis, and release tension
on the abdominal wall.
▪ Successful primary closure is of utmost importance since it is associated with
decreased overall costs, decreased inflammation and fibrosis of the bladder,
improved bladder growth, and decreased need for urinary diversion
35. The modern staged repair of exstrophy
(MSRE)
A. The first stage is the abdominal wall and bladder closure.
▪ Females: genitoplasty and urethroplasty with this first procedure.
▪ this stage may be delayed if the bladder template is too small or covered with polyps.
B. The second stage in males is to close the urethral epispadias at 6 to 12 months .
C. The third stage, a continence procedure such as the Young-Dees-Leadbetter BNR, is
delayed until a bladder with adequate capacity and desires continence (5 and 9
years of age).
▪ This stage is combined with ureteral reimplantation to repair VUR.
▪ Children who are not candidates for BNR or who fail to achieve urinary continence
after the procedure may require bladder neck transection, AC, and continent
catheterizable stoma.
36. initial bladder closure in a staged repair for bladder exstrophy in the male patient.
(1) completion of dissection around the bladder and urethral plate;
(2) placement of a suprapubic drainage tube after corporeal reapproximation;
(3) Tubularization of the urethral plate over the catheter;
(4) following two-layer closure of the bladder and urethral plate, the bladder is reduced
in the pelvis and fixed with sutures;
(5) drainage tubes are brought out superiorly and the fascia, subcutaneous tissue, and
skin are reapproximated.
37. Principles of the Young–Dees–Leadbetter procedure.
▪ This is performed as the third stage of a staged reconstructive approach to exstrophy.
The ureters are reimplanted as shown here to prevent vesicoureteral reflux and move
them out of the area of the bladder neck reconstruction.
▪ The base of the bladder is reconstructed to lengthen the urethra and reinforce the
bladder neck.
38. Complete primary repair for exstrophy
(CPRE)
▪ combines primary abdominal wall and bladder closure with epispadias repair
and partial tightening of the bladder neck.
▪ bilateral ureteral reimplantationcan safely be done during this surgery to
reduce the risk of future febrile urinary tract infection and hydronephrosis
▪ this technique may decrease costs, decrease the morbidity associated with
multiple operations, and stimulate early bladder growth.
▪ The epispadias repair is done by “penile disassembly,” where the urethral
plate is fully dissected from the corporal bodies.
▪ many children still require surgery for resulting hypospadias, persistent
vesicoureteral reflux, incontinence, or failed primary closure
39. ▪ Initial lines of dissection for male complete primary exstrophy repair technique –
ventral perspective.
▪ Initial lines of dissection for male complete primary exstrophy repair – dorsal
perspective. Lines at the bladder neck indicate approximate tailoring that may be
needed to exclude dysplastic tissue in this area.
40. Disassembly of the urethral wedge
(urethral plate with underlying corpora
spongiosa) from corporeal bodies. The
plane of dissection should remain on
the corporeal bodies to allow the
corpora spongiosa to remain with the
urethra.
Distal separation of the corporeal bodies
and urethral wedge. This maneuver may
not always be required. Complete
separation allows maximal exposure to the
pelvis and optimizes the dissection and
posterior positioning of the bladder,
bladder neck, and urethra in the pelvis.
41. Division of the intersymphyseal band
(condensation of anterior pelvic fascia)
and deep pelvic
dissection. The inset demonstrates
division of the
intersymphyseal band. Division of this
band allows
posterior placement of the bladder
without tension.
42. This cross section represents an idealized positioning of the
urethra and bladder neck in the pelvis.
43. The bladder and urethra are closed in
two layers using absorbable suture. The
ureteral
catheters are brought out throught the
urethral closure.
The suprapubic tube may be brought out
through the
umbilicus.
44. Pelvic Osteotomies and Immobilization
▪ in patients who no longer have a malleable pelvis, (after 72 hours of age).
▪ they increase surgery time and risk for postoperative complications.
▪ They improve success of primary closure
▪ A combination of bilateral anterior transverse innominate and vertical
posterior iliac osteotomies.
▪ At the time of osteotomy, fixator pins and external fixation devices can be
placed and left for 4 to 6 weeks as the patient is immobilized .

46. ▪ Modified Buck’s traction exerts pull longitudinally on the lower extremities
and is used after osteotomy.
▪ Modified Bryant’s traction, where the hips are placed into 90 degrees of
flexion, may be used if there is no osteotomy.
▪ Spica casts also immobilize the pelvis without the need for external fixators or
traction

48. Bladder Augmentation
▪ After having failed one attempted CBE closure, the chance of achieving
adequate bladder capacity for a BNR and continent urethral voiding, decreases
to 60% .
▪ A bladder that is noncompliant or of insufficient capacity may undergo AC.
▪ Common techniques utilize segments of bowel, stomach, or redundant ureter
to expand the bladder wall.
▪ Continent Urinary Diversion. required when a patient undergoes AC.
▪ A segment of appendix or ileum may be utilized to connect the bladder to the
skin and provide a continent stoma through which to perform CIC
49. Modern Functional Reconstruction of
Cloacal Exstrophy
▪ Immediate Neonatal Assessment and Evaluate associated anomalies
▪ Decide whether to proceed with reparative surgery
▪ Functional Bladder Closure (Soon after Neonatal Assessment)
▪ ONE-STAGE REPAIR (FEW ASSOCIATED ANOMALIES)
✓Excision of omphalocele
✓Separation of cecal plate from bladder halves
✓Joining and closure of bladder halves and urethroplasty
✓Bilateral anterior innominate and vertical iliac osteotomy
✓Gonadectomy in males with unreconstructible phallus
✓Terminal ielostomy/colostomy
✓Genital revision if needed
50. TWO-STAGE REPAIR
▪ First stage (newborn period)
✓ Excision of omphalocele
✓ Separation of cecal plate from bladder halves
✓ Joining of bladder halves
✓ Gonadectomy in male with unreconstructible phallus
✓ Terminal ileostomy/colostomy
▪ Second stage
✓ Closure of joined bladder halves and urethroplasty
✓ Bilateral anterior innominate and vertical iliac osteotomy
✓ Genital revision if necessary
51. ▪ Anti-Incontinence/Reflux Procedure (age 5 yr)
✓ Bladder capacity ≥ 85 mL (small select group of patients)
✓ Young-Dees-Leadbetter bladder neck reconstruction
✓ Bilateral Cohen ureteral reimplantations
✓ Bowel and/or stomach segment used to augment bladder Or Continent
diversion with abdominal/perineal stoma
▪ Vaginal Reconstruction
Vagina constructed or augmented using colon, ileum, or fullthickness skin graft
52. LONG-TERM ISSUES IN CLOACAL EXSTROPHY
▪ Bowel and continence problems
▪ Fertility appears to be universally compromised in boys, but girls have normal
fertility and pregnancy has been reported.
▪ Girls have higher degrees of cervical prolapse when compared with their
counterparts with bladder exstrophy
▪ Despite the extensive malformations noted, many patients have gone on to
live fruitful lives.
