DURING PREGNANCY :

CIRCLAGE OPERATION TWO TYPES : SHIRODKAR’S AND Mc DONALD’S

(a)COMPETENT CERVIX (b) INCOMPETENT CERVIX WITH HERNIATION OF MEMBRANES (c)COMPETENCY RESTORED AFTER ENCIRCLAGE OPERATION

STEPS OF SHIRODKAR’S OPERATION STEP 1 : THE PATIENT IS PUT UNDER GENERAL ANESTHESIA AND PLACED IN LITHOTOMY POSITION WITH A GOOD EXPOSURE OF THE CERVIX BY A POSTERIOR VAGINAL SPECULUM. THE LIPS OF THE CERVIX ARE PULLED DOWN BY ALLIS TISSUE FORCEPS. STEP 2 : A TRANSVERSE INCISION IS GIVEN ANTERIORLY BELOW THE BASE OF THE BLADDER ON THE VAGINAL WALL AND THE BLADDER IS PUSHED UP TO EXPOSE THE LEVEL OF THE INTERNAL OS. A VERTICAL INCISION IS GIVEN POSTERIORLY ON THE CERVICOVAGINAL JUNCTION.

STEP III – THE NON ABSORBABLE SUTURE MATERIAL – NO.4 IS PASSED SUBMUCOUSLY WITH THE HELP IF ANEURYSMAL NEEDLE SO AS TO BRING THE SUTURE ENDS THROUGH THE THE POSTERIOR INCISION. STEP IV – THE ENDS OF THE SUTURE ARE TIED UP POSTERIORLY BY A REEF KNOT. THE BULGING MEMBRANES, IF PRESENT MUST BE REDUCED BEFOREHAND INTO THE UTERINE CAVITY. THE ANTERIOR AND POSTERIOR INCISIONS ARE REPAIRED BY INTERRUPTED STICHES USING CHROMIC CATGUT.

Mc DONALD’S OPERATION THE NON ABSORBABLE SUTURE MATERIAL IS PLACED AS PURSE STRING SUTURES AS HIGH AS POSSIBLE AT THE JUNCTION OF THE RUGOSE VAGINAL EPITHELIUM AND THE SMOOTH VAGINAL PART OF THE CERVIX BELOW THE LEVEL OF THE BLADDER. THE SUTURE STARTS AT THE ANTERIOR WALL OF THE CERVIX. TAKING SUCESSIVE DEEP BITES IT IS CARRIED AROUND THE LATERALAND POSTERIOR WALLS BACK INTO THE ANTERIOR WALL AGAIN WHERE THE TWO ENDS OF THE SUTURE ARE TIED.
