He has already authored SRB’s Manual of Surgery; SRB’s Surgery for Nursing Students, SRB’s Surgery for Dental Students and Jaypee Gold Standard Mini Atlas Series: Surgical Diseases. This new innovation of his, SRB’s Bedside Clinics in Surgery is of different type with illustrations, clinical methods, X-rays, discussion on surgical pathology and basic surgical procedures. It is more of clinical and practical book by which undergraduate and surgical postgraduate students will be benefited. It will also be useful in the process of learning to any practitioner who still has the zeal to learn. I am proud of the fact that a student of mine has reached such heights of excellence and I feel privileged to be given the honor of penning the foreword for this special book. I wish him success in all his endeavors which I am sure will be an inspiration for every young aspiring surgeon. Thangam Verghese Joshua MS MCh Head, Department of Surgery Kasturba Medical College Mangalore 575 001 Karnataka, India  Preface It is observed that students, especially undergraduates, often find difficult to prepare themselves for clinical examination after theory papers. They need to know basic clinical methods with relevant discussion of the specific cases; X-ray discussion; surgical specimens; instruments; basic operative procedures and principles. Keeping this in mind, this book SRB’s Bedside Clinics in Surgery has been brought out to go through quickly prior to clinical examinations. This is also useful to surgical residents and postgraduates, especially for instruments and surgical pathology, which are of great importance to them. Many a times, students need to refer to SRB’s Manual of Surgery, 3rd edition (whenever required) and other specific books for detailed theory aspects of many topics. I hope this book will earn its value in its own way in student circle. I thank everybody including publishers who are backbone of this title. Any criticisms are well accepted.

Why it is indirect inguinal hernia? It is pyriform in shape. It descends obliquely in the groin. On occluding the internal ring in ring occlusion test, swelling does not appear later on coughing. On ring invagination test, impulse is felt at the tip of the invaginating finger. Zieman’s test confirms the impulse over the index finger. If it is direct inguinal hernia, then what A are the differentiating features? Direct inguinal hernia is globular in shape. After occluding the deep ring, swelling still appears on coughing on the medial side of the inguinal region. Impulse is felt on the pulp of the finger in invagination test and over the middle finger in Zieman’s test. How expansile impulse on coughing is clinically demonstrated? B Expansile impulse on coughing is seen on Figs 1.10A and B: In inguinoscrotal swelling inspection when patient is asked to cough. one cannot get above the swelling. 12 SRB's Bedside Clinics in Surgery ring occlusion test/invagination test/Zieman’s test if hernia is irreducible. How is finger invagination test done? Patient is asked to lie down. Contents are reduced completely. Using the little finger, scrotal skin is invaginated from below upwards near upper part of the testis. Finger is reached towards the superficial inguinal ring/external ring. Normally external ring does not admit the tip of the little finger. Finger is rotated inwards so that nail is towards the cord side. Patient is asked to cough. Fig. 1.11: Ring occlusion test is done to find out whether If the impulse is felt on the tip of the finger, then hernia is direct or indirect. If after occluding the ring swelling it is indirect inguinal hernia. If impulse is felt appears on the medial side, it is direct hernia.

(Note: Mid point of the inguinal ligament is center point between anterior superior iliac spine and pubic tubercle). Patient is asked to lie down to reduce the hernial contents. Thumb is placed over the mid-inguinal point. Patient is asked to cough. If there is expansile impulse on coughing on the medial side of the A thumb, in spite after deep ring occlusion, it is then direct inguinal hernia. If there is no impulse on coughing then patient is asked to stand with thumb occluding the deep ring. Patient is once again asked to cough; impulse on the medial side of the occluded thumb is looked for to rule out the direct inguinal hernia. If there is no impulse even on standing, it is indirect inguinal hernia. The occluded thumb is removed and patient is asked to cough to show the swelling and impulse due to indirect inguinal hernia.

Abdominal muscle tone is checked by head rising (without supporting the elbows) or leg rising tests. It is initially inspected for any bulges in the abdominal wall which signifies Malgaigne bulgings. Later abdomen should also be palpated for muscle tone. Firmness signifies adequate tone whereas suppleness signifies poor muscle tone. Poor muscle tone indicates that patient needs B hernioplasty using mesh. Abdominal muscle tone is also checked by Valsalva manoeuvre.

It takes 6 months to achieve more than 80% of tensile strength in repaired hernial wound; and so non-absorbable suture material has to be used here to maintain the same adequate tensile strength in these period. Multifilament suture material like silk may precipitate infection because of the crevices in the suture material and tensile strength is not as good as monofilament suture material. Commonly used suture material is either polypropelene (prolene (blue in colour)) or polyethylene (ethylon (black in colour)). Continuous sutures compromise the blood supply and interfere with proper healing; and strength will not be as adequate as interrupted sutures. So always interrupted sutures are used. Earlier, commonest surgery done for groin inguinal hernia is modified Bassini’s repair. But now hernioplasty is the commonly done procedure for both direct and indirect sac. In direct hernia, sac is usually not opened but Fig. 1.27: Cord holding forceps is used to in indirect hernia, sac is always opened. hold cords in inguinal hernia surgery. What is herniotomy? Herniotomy is done for indirect sac, where the sac is dissected, neck of the sac is ligated and redundant sac is excised. What are the steps in inguinal hernia surgery? What are the different modifications? 1. Herniotomy Procedure After cleaning and draping, skin is incised 1.25 cm above and parallel to the medial two/ third of inguinal ligament. Two layers of superficial fascia (outer Camper’s fascia and inner Scarpa’s fascia) are incised. External oblique aponeurosis is incised.
