POSTOPERATIVEMANAGEMENT
Counselpatientstomaintainstoolsoftwithhydration,fiberuse,and stoolsoftener.Minordiscomfortshouldbemanagedwith acetaminophen.
Patientsshouldbereevaluatedandconsideredforarepeatedbanding attempt6weeksaftertheinitialbanding.Surgicalexcisioncanbe consideredforgradeIIIhemorrhoidsthatpersistdespitebanding.

COMPLICATIONS

Althoughfrequentlyfatalwhenitdoesoccur,postbandingsepsisisrare. Vigilanceandearlytreatmentarevital.Patientsshouldbeadvisedthat increasingpain,urinaryretention,orfevershouldprompturgent evaluationastheycouldbetheharbingerofpostbandingsepsisorpelvic cellulitis.Treatmentofpostbandingsepsisrequiresearlyintravenous antibiotics,bandremoval,debridementofnecrotictissue,andsupportive careinanintensivecareunit.Therearereportsofpostbandingsepsis developingintoFournier’sgangrene.Urinaryretentionismorefrequent whenmultiplequadrantsarebandedatonesetting.
OthercommoncomplicationsofRBL(<5%ofpatients)arerectal bleeding,pain,vasovagalsymptoms,thrombosedexternalhemorrhoids, andrarely,bacteremia.Bleedingoccurswhenthebandedtissuesloughs offtypically4–10daysafterbanding.Thebleedingisoftenself-limited, butmaybesignificantenoughtowarrantanemergencyroomvisit,andin rarercases,examinationunderanesthesiaforsuturesatthebaseofthe pedicle.

RESULTS

Asingle-institutionreviewbyWrobleskiof266patientswhounderwent RBLwithameanfollow-upof60monthsshowed80%hadimproved symptoms,with69%totallyfreeofallsymptoms,andonly7.5%requiring subsequenthemorrhoidectomy.Iyer’sretrospectivereviewof805 patientswhounderwent2,114rubberbandligatures,notedsuccess (permanentrelieformarkedimprovementofsymptoms)in80.3%of patientwithinthefollowingperiodof1year.Thisreviewnoted complicationsofbacteremia(0.09%)andbleeding(2.3%),which unsurprisinglywasincreasedinpatientsonAspirin,nonsteroidalanti­inflammatorydrugs,andwarfarin.Bayerreviewed2,934patientswith gradesIIandIIIhemorrhoidswhoweretreatedbyRBL(usuallyone ligationpersession),79%werecompletelycured,18%neededadditional sessionsoftreatment,and2.1%failedtobecuredbyRBLandwere referredforhemorrhoidectomy.

CONCLUSIONS

RBLisawell-toleratedandeffectiveoffice-basedtreatmentfor symptomaticgradesI,II,orIIIhemorrhoidsoncemedicaltherapyfails. Recurrenceafterbandingcanbemanagedwithrepeatbandingor surgicalexcision.PelvicsepsisafterRBLisrare,butearlyrecognitionand treatmentisvital.

INTRODUCTION

Themanagementofanalfistularemainsachallengeforsurgeonsbecause oftheheterogeneityoftheconditionandthepotentialadverseeffecton continenceasaresultofsurgery.Inaddition,aswellasbeinga frustratingproblemforpatients,itcanhaveadevastingeffectontheir qualityoflife.
Themajorityofperianalsepsisisidiopathicorcryptoglandularin origin,andarisesfromtheobstructionofanalglands,leadingtostasisof glandularsecretionsand,ifsecondarilyinfected,suppurationandabscess formation.Theabscesstypicallyformsintheintersphinctericspace,but canextendintotheischiorectalfossaorsupralevator/suprasphincteric spaces.Followingeitherspontaneousorsurgicaldrainageoftheabscess, apersistentfistulatractdevelopsinabout30–50%ofpatients,extending fromtheanalcanal(usually)totheperinealskin.
Aminorityofcasesareassociatedwithotherdiseaseprocessesor conditionsincludingCrohn’sdisease,radiation,malignancy,trauma, foreignbody,previoussurgery(includingileoanalpouchsurgery), tuberculosis,HIVinfection,hidradenitissuppurativa,lymphogranuloma venereum,perianalactinomycosis,andrectalduplication.Inthese situations,thefistulatractisoftenatypical.
Treatmentisaimedatcure,withthedrainageofanyassociatedsepsis anderadicationofthefistulatract,whilepreservingtheintegrityand functionoftheanalsphinctercomplex.Allmethodsoffistularepairrely ontheeliminationoftheinternalopeningofthefistulatract,whichinthe caseofcryptoglandularfistulasistheopeningoftheanalgland.
Fistulotomyremainsthemainstayoftreatmentforlowfistulatracts, thatis,thosefistulasinvolvinglessthanthedistalthirdoftheinternal
analsphinctercomplex.Thechallengeliesinthetreatmentofhightract; inthissituation,asimplefistulotomyisprecludedbecausethedivisionof internalandexternalsphinctermuscleswouldresultinanunacceptably highrateofincontinence.Asaresult,sphincter-sparingtechniqueshave beendeveloped.Theseincludethecontrolofthetractwithalong-term setondrain,simpleexcisionandclosureoftheinternalopening,mucosal anddermaladvancementflaps,fatandmuscletranspositionalflaps,the ligationoftheintersphinctericfistulatract(LIFT)procedure,theuseof fibringlueandbioprostheticfistulaplugs,andmorerecently,injections ofadipose-derivedstemcellsordermalcollagen.Ofthese,themucosal advancementflap(MAF)isthemostinvestigatedtechniqueavailable.
SimpleExcisionandAppositionalClosureofthe InternalOpening
Someauthorshavereportedtreatingthefistulatractbysimplyclosing theinternalopening,withoutusinganadvancementflap.Theargument forthistypeofrepairisthatinthepresenceofadequateperfusionand theabsenceofunduetension,atthecoaptedsurfaces,simple appositionalclosureshouldsufficeandthistypeofrepairmaintainsthe sphincterintegrity.Althoughthisprocedureisnotpracticedatour institution,asithasbeenshowntobeinferiortothemethodsusingflap reinforcement,andisgenerallycombinedwithaflapadvancement procedurenow,and/orafistulotomy,brieflymentionedherefor completeness.

Closureisachievedusingathree-layer,nonstaggeredtechnique,closing themucosaandsubmucosa,theinternalandtheexternalsphincter muscles.TheLIFTprocedureisamodificationofthistechniqueandis discussedindetailelsewhere.

INDICATIONS/CONTRAINDICATIONS

Advancementflapproceduresmaybeconsideredinanypatientinwhom thefistulatractiscomplexandcannotbelaidopen.Acomplexfistula tractisdefinedasonethatinvolves>30%oftheexternalsphincterand includestractsthatarehightranssphincteric,suprasphincteric,and extrasphincteric;ortractsthatarerectovaginalorrectourethral,anterior infemalepatients,multiple,orrecurrent.Inaddition,atractiscomplex ifitisassociatedwithanunderlyingdiseaseprocess,aslistedabove, includingCrohn’sdisease,orthepatienthaspreexistingcompromised sphincterfunction.
Theflapmaybemobilizedfromtherectumaseitheramucosal,partial thickness,orfull-thicknessrectaladvancementflaporfromtheperianal skinasananocutaneousadvancementflap.
Relativecontraindicationstoperformingaflaprepairinclude:
undrainedsepsis afistulaoflessthan4-weekduration amalignantfistula afistulaarisinginanirradiatedfield thepresenceofactiveproctitis,particularlyCrohn’sdisease
Ananocutaneousflapwouldpreferablybeusedoverarectal advancementflapifthereisananorectalstricture;thistypeofflapisalso usedtorepairkeyholedeformitiesrelatedtosphincterdefectsand scarringasaresultofpreviousfistulotomies.
