This document provides an overview of abdominal wall hernias, including definitions, types, etiologies, anatomy, clinical features, and treatments. It describes the main types of groin hernias such as indirect, direct, and femoral hernias. It discusses the composition of hernias and provides classifications. For groin hernias specifically, it outlines the anatomy of the inguinal canal and contents, compares indirect and direct hernias, and describes surgical repair techniques like Bassini, Shouldice, and Lichtenstein. Femoral hernias are also summarized, including the anatomy of the femoral ring and canal.
Inguinal and femoral hernia:
A hernia is a protusion of a viscus or a part of viscus through and abnormal opening in the walls of its containing cavity. Details of inguinal hernia and few slides on other types of hernia.
Intestinal fistulas pose the greatest challenge to the General Surgeon. The presentation provides abrief guideline for management of this complex problem.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. CONTENT’S
• DEFINITION
• TYPES OF HERNIA AND ETIOLOGY
• COMPOSITION OF HERNIA
• CLASSIFICATION OF HERNIA AND CONTENTS OF
HERNIA .
• ANATOMY OF HERNIA AND CLINICAL FEATURES
• DIFFERENT KINDS OF TEST
• MANAGEMENT.
5. Etiologies
• Increased abdominal pressure
– Cough, urinary trouble, constipation, straining, ascites,
intra abdominal malignancies, pregnancy
• Weakness of abdominal wall
– Congenital
• Patent processes vaginalis, patent canal of nuck in females
– Acquired
• Excess fat (obesity)
• Post Pregnancy
• Surgical incisions
• Connective tissue disorders like Marfan’s syndrome
6. Composition of a hernia
• A hernia consists of three parts –
– the sac
– the coverings of the sac
– the contents of the sac
• The sac is a diverticulum of peritoneum, consisting of
– Mouth
– Neck
– Body
– Fundus
• The coverings are derived from the layers of the
abdominal wall through which the sac passes.
7. Contents
• omentum = omentocele;
• intestine = enterocele; more commonly small
bowel but may be large intestine or appendix;
• a portion of the circumference of the intestine =
Richter’s hernia;
• a portion of the bladder (or a diverticulum);
• ovary with or without the corresponding fallopian
tube;
• a Meckel’s diverticulum = a Littre’s hernia;
• fluid, as part of ascites or peritoneal fluid.
8. Classification of Hernia
• Reducible – if contents can be returned to abdomen
• Irreducible – if contents cannot be returned but there
are no other complications
• Obstructed – if bowel in the hernia has good blood
supply but bowel is obstructed
• Strangulated – if blood supply of bowel is obstructed
• Inflamed – if contents of sac have become inflamed
• Incarcerated – if the portion of the colon occupying a
hernial sac is blocked with faeces
10. Nyhus Classification of Groin Hernia
• Type I: Indirect inguinal hernia with internal inguinal ring normal
• Type II: Indirect inguinal hernia with internal inguinal ring dilated
but posterior wall intact, inferior epigastric vessels not displaced
• Type III: Posterior wall defect
A: Direct inguinal hernia
B: Indirect inguinal hernia with internal inguinal ring dilated,
medially encroaching on or destroying the transversalis fascia of
hesselbach’s triangle.
C: Femoral hernia
• Type IV: Recurrent hernia
A: Direct B: Indirect C: Femoral D: Combined
11. Anatomy of inguinal canal
• 4 cm in length passing downward and medially
from deep to superficial ring
• Deep/internal ring is ‘U’ shaped in fascia
transversalis which lies 1.25 cm above the mid
inguinal point.
• Superficial/External ring is in external oblique
aponeurosis situated just above and lateral to the
pubic crest.

16. Boundaries of the inguinal canal
• Anterior – aponeurosis of the external oblique muscle
• Inferior (floor) – inguinal ligament and lacunar
ligament on medial side
• Superior (roof) – the arching fibers of the internal
oblique and the transversus abdominis muscles
• Posterior – transversalis fascia, reinforced medially by
the conjoint tendon
17. Contents of Inguinal Canal
• Ilioinguinal Nerve
• Spermatic Cord (in male)-
• Round ligament (in female)
19. Natural mechanism of preventing
inguinal hernia
• Obliquity of canal.
• Shutter action of arched fibers of internal
oblique and transverse abdominis.
• Plugging action of spermatic cord due to
contraction of cremestaric muscles.
23. Direct Inguinal Hernia
• A direct inguinal hernia is always acquired.
• The sac passes through a weakness or defect of the
transversalis fascia in the posterior wall of the
inguinal canal.
24. Clinical Features
• Symptoms • Signs
– Swelling – Inguino-scrotal swelling
– Expansile cough
– Dragging pain
– Cannot get above the
– h/o suggesting swelling
increased abdominal – Reducibility
pressure – Finger invagination test
– Symptomless – Deep ring occlusion test
– Accidental finding – Ziemen test (Three
finger test)

30. Surgical Treatment
• Herniotomy (excision of hernia sac)
– Usually done in children
• Herniorrhaphy (herniotomy with strengthening of the posterior wall)
– Bassini repair
– Shouldice repair
– McVay repair
• Hernioplasty (herniorrhaphy with application of prosthesis)
– Lichtenstein repair
– Plug and patch repair
• Laparoscopic repair
– TEP (Total Extra Peritoneal)
– TAPP (Trans Abdominal PrePeritoneal)
32. Shouldice Repair
• Multilayer repair of the posterior wall of the inguinal canal
• Double breasting of transversalis fascia
• Transverse abdominis aponeurotic arch to the iliopubic tract
and Conjoined tendon to the inguinal ligament
34. Lichtenstein Repair
• A piece of prosthetic non-
absorbable mesh is
placed to fit the canal
• The mesh is sutured to
the aponeurotic tissue
overlying the pubic bone
medially, continuing
superiorly along the
transversus abdominis or
conjoined tendon.
• The inferolateral edge of
the mesh is sutured to
the inguinal ligament
35. Femoral Hernia
• Femoral hernia enters the femoral ring,
traverses the femoral canal and comes out
through the saphenous opening.
• The female to
male ratio is
about 2:1.
• The right side is
affected twice
as often as the
left.
36. Femoral Ring
• Oval opening ½” to 1” in diameter
• Boundaries
• Anteriorly inguinal
ligament
• Posteriorly
iliopectineal
ligament, pubic bone
and fascia over
pectinious muscle
• Medially lacunar
ligament
• Laterally septum
separating from
femoral vein.
37. Femoral Canal
• Most medial compartment of femoral sheath.
• Conical in shape, 1.25 cm long and 1.25 cm wide at base
(Femoral ring).
• Extends from Femoral ring (above) up to saphenous opening
(below).
• Contents- fats, lymphatic and lymph nodes of Cloquet.
38. Saphenous Opening
• An oval opening in the
supero-medial part of
the fascia lata of the
thigh.
• Lies 3–4 cm infero-lateral
to the pubic tubercle.
• Long saphenous vein and
femoral branch of genito-
femoral nerve traverses
through this opening.
39. Surgical Treatment
• The low (Lockwood) operation- the inguinal
ligament to the iliopectineal ligament.
• The high (McEvedy) operation- the conjoint
tendon to the iliopectineal ligament.
• Lotheissen’s operation- the conjoint tendon
or inguinal ligament to the iliopectineal
ligament through inguinal canal
