VOLVULUS DR.M.RAVICHANDRA,M.S ASST.PROF OF SURGERY RIMS,SRIKAKULAM DEFINITION A VOLVULUS IS TWISTING OR AXIAL ROTATION OF A PORTION OF BOWEL ABOUT IT’S MESENTRY VOLVULUS OBSTRUCTION CAUSED BY TWISTING OF THE INTESTINES MORE THAN 180 DEGREES ABOUT THE AXIS OF THE MESENTERY 1-5% OF LARGE BOWEL OBSTRUCTIONS SIGMOID ~ 65% CECUM ~25% TRANSVERSE COLON ~4% SPLENIC FLEXURE TYPES PRIMARY&SECONDARY PRIMARY CONGENITAL MALROTATION OF GUT ABNORMAL MESENTERIC ATTACHMENTS CONGENITAL BANDS SECONDARY ACQUIRED ADHESION (OR) STOMA SIGMOID VOLVULUS WORLDWIDE - UP TO 50% OF OBSTRUCTION INDIA, AFRICA, E.
