Irreducible Hernia Due to Adhesions Narrowing of neck Incarceration Massive hernia inside scrotum
Obstructed Hernia Irreducibility + Intestinal obstruction Features No cough impulse Irreducible Painless Non tender Features of intestinal obstruction
Strangulated Hernia Blood supply of its contents impaired Intestinal obstruction ± Pathology Intestinal obstruction Dilation of hernial contents Impairment of venous return Stasis --------- Arterial impairment
Appearance Congested and bright red Ecchymosis Extravasation of blood into lumen/ sac loss of tone Translocation of gut bacteria – peritonitis/ sepsis Gangrene
Symptoms Pain, vomiting Ceases with onset of gangrene, ileus Signs Ill looking Tense, tender Irreducible, no cough impulse Acute intestinal obstruction Peritonitis
Strangulated Omentocele No features of intestinal obstruction Gangrene onset delayed
Strangulated Richter’s Hernia Features mimic gastroenteritis Obstruction > 50 % of circumference Colic, diarrhoes Constipation - ileus
Maydl’s Hernia Retrograde strangulation On opening sac – contents appear normal Generalized peritonitis may set in early
Inflamed Hernia Outside Abrasion, ill fitting truss Inside Diverticulitis, appendicitis Signs of inflammation + Not associated with intestinal obstruction
Inguinal hernia
Anatomy
Inguinal canal Triangular slit 3.75 cm long Above the inner half of inguinal ligament Deep to superficial inguinal ring Developed due to the descent of testis in embryonic life
Deep Inguinal Ring Opening in the fascia transversalis 1.25 cm above mid inguinal point Medially – inferior epigastric artery Spermatic cord in males; round ligament in females
Superficial Inguinal Ring Aponeurosis of external oblique – crurae Above and lateral to pubic crest Spermatic cord/ round ligament and illio -inguinal nerves
Anteriorly – skin, fascia, EO aponeurosis , lateral third – IO aponeurosis Posteriorly – transversalis fascia, medial ½ - conjoint tendon Above – transversus abdominins and internal oblique fibres Below – inguinal ligamnet
Contents Illioinguinal nerves Spermatic cord Vas defrens Testicular artery, art to vas defrens , cremasteric Pampiniform plexus of veins Lymph vessels Testicular plexus of sympathetic nerve s, genital branch of genitofemoral
Hassenbach’s Triangle Site of direct hernia Medially – lateral border rectus abdominis Laterally – inferior epigastric vessel Inferiorly – inguinal ligament Floor – fascia transversalis Umbilical fold – obliterated umbilical artery
Mechanisms for preventing hernia Obliquity of inguinal canal Shutter mechanism of fibres of IO, TA Sphincter action of TA, IO at deep inguinal ring Ball valve action of cremasteric Fibres of internal oblique over deep inguinal ring Conjoint tendon
INDIRECT INGUINAL HERNIA More common Young individuals More common on the right side On basis of extent Bubonocele Funicular hernia Complete hernia
Coverings Peritoneum Extraperitoneal fat Internal spermatic fascia Cremasteric fascia External spermatic fascia Superficial fascia skin
DIRECT INGUINAL HERNIA Directly through the hasselbach’s triangle Acquired (ex- Oglive hernia) More common in elderly, malgaigne bulgings Rarely gets strangulated
Symptoms Pain/ discomfort Lump Systemic symptoms – obstruction, strangulation Predisposing factors – constipation, chronic bronchitis, urinary obstruction Past history
Signs REDUCIBILITY COUGH IMPULSE Position – d/f femoral hernia Get above the swelling Invagination test Ring occlusion test
Rare Varieties Interstitial hernia Between muscle layers of abdominal wall Commonly associated with undescended testis Preperitoneal Intraperitoneal Extraperitoneal
Rare Varieties Sliding hernia Older men Extraperitoneal bowel with sac of peritoneum Caecum , pelvic colon, bladder Strangulation of intestine within and outside the peritoneum Richter’s Maydl’s Littre’s
Conservative management : No Treatment Indications Severe ill health Short life expectency Refuse operation
Conservative management : Truss Indications Refuse operation Old patients with severe co morbidities Children ( c/I – undescended testis) Contraindications Irreducible hernia Undescended testis Chronic bronchitits , strenous labour Associated with large hydrocele Not intelligent enough to position properly
Dangers Pressure atropht of muscles of inguinal region Ostruction or strangulation Used with partially reduced hernia – may cause trauma Improper cleanliness – unhealthy skin Adhesions between sac and canal Chance of strangulation remains
Operative treatment Herniotomy Neck of sac transfixed, ligated and excised Infants and children ; young men with good musculature Herniorrhaphy Herniotomy + repair of postrior wall Indirect hernias Adults with good muscle tone
Hernioplasty Herniotomy + reinforcement of posterior wall Autologous Fascia lata External oblique aponeurosis Anterior rectus sheath flap Skin flap – dermoplasty / skin ribbon Heterogenous Prolene Stainless steel
Indications Indirect hernia – poor muscle tone Direct hernia Recurranthernia Predisposing factors – chronic cough,etc
Treatment of Strangulated Hernia Emergency surgery Resuscitation Reduction of hernia Foot end elevation Ice pack NG, IV fluids Analgesia, antibiotic
Assess viability Green/ black color Flaccid , lustureless appearance No peristalssis Blood stained, foul smelling fluid in sac Bowel viable - HERNIORRHAPHY
Bowel nonviable Linear patch of gangrene – invagination Loop of bowel – resection and anastomosis if gen condition permits Bowel large intestine – exteriorisation
RECURRENT INGUINAL HERNIA Types of hernia Sliding Large/ long standing Large direct hernia Types of patients – chronic cough Inadequate preoperative preparation
RECURRENT INGUINAL HERNIA Operative faults Failure to ligate sac Tension in repair Use of absorbable sutures Bleeding – infection Fault in selection of operation Postoperative care Wound infection Lifting heaavy weights Persistence of predisposing factors Appearance of new hernia
FEMORAL HERNIA
Femoral ring – femoral canal – saphenous opening More common in Females Old age Most liable to strangulate
Anatomy
Coverings of the sac of femoral hernia Skin Superficial fascia Cribriform fascia Anterior layer of femoral sheath Fatty contents of femoral canal Femoral septum Peritoneum
Symptoms Swelling Pain Systemic symptoms Zeimenns technique Invagination technique Ring occlusion test Position of swelling
Treatment No conservative management Surgery – herniorrhaphy High operation( McEvedy’s ) Lottheissen’s Lockwood
UMBILICAL HERNIA Three major types Exomphalos Umbilical hernia in infants and children Paraumbilical hernia in adults
Exomphalos Minor Small sac Summit attached to the umbilical cord Treatment twisting of umbilical cord and strapping
Exomphalos Major Umbilical cord attached to inferior aspect of swelling Contains intestines, liver Surgical emergency Immediate decompression and reduction
Umbilical hernia in children and infants Weak umbilical scar following neonatal sepsis Usually asymptomatic 90% cured within 12 – 18 months > 18 months – surgery
Paraumbilical hernia of adults Supraumbilical or infraumbilical Adhesions - seldom reducible Predisposing factors – Women Obesity Repeated pregnancy Treatment – Mayo’s operation
EPIGASTRIC HERNIA ( Fatty Hernia of Linea Alba) Through fibres of linea alba Blood vessels pierce linea alba Initially extraperitoneal fat only M.c . – young muscular men with strenous activity Usually irreducible, no cough impulse If symptomatic - surgery
INCISIONAL HERNIA ( Ventral Hernia) Defect with patient Obesity Chronic cough perioperative period Undue abdominal distention Malnutrition Operative Injury to nerves Careless wound closure Hemorrhage – infection Tube drainage through laparotomy wound Midline infraumbilical
Postoperative Infection Postop cough, distention Postop peritonitis Early removal of sutures Postop steroid therapy
Types of incisional hernia Type 1 Upper abdomen/ midline lower abdomen Wide gap in musculature Low risk of strangulation Type 2 Lateral part of abdomen Small defect Strangulation risk high
Treatment Prevention of incisional hernia Weight reduction Correct nutritional defects Treat chronic cough Careful closure of abdomen Prevent post op wound infection
Conservative management Reducible type 1 SURGICAL MANAGEMENT
LUMBAR HERNIA Superior lumbar hernia Inferior lumbar hernia
Incisional lumbar hernia Renal surgery with post op infection Paralysis of lumbar muscles( phantom hernia ) Treatment Primary hernia – herniorrhaphy Incisional hernia
OBTURATOR HERNIA Rare; old women Through obturator foramen Thigh flexed, abducted and externally rotated Referred pain to knee joint Strangulation - surgery
SPIGELEAN HERNIA Interparietal hernia At level of arcuate line, lateral to rectus Treatment - surgery
Gluteal hernia Sciatic hernia
CONCLUSION Protrusion of a part or whole of viscus through an abnormal opening in the wall of the cavity that contains it Inguinal hernia most frequent Usual mode of treatment is surgical
