CAUSES OF VOLVULUS
•Chronic constipation•Neuropsychotropic drugs•Elderly population (care
homes)•Pregnancy •High fibre diets•Chagas disease
VOLVULUSDiagnosis
• Sudden onset abdominal pain
• Previous history
• Distended, resonant abdomen
–NB Tenderness and guarding
• Plain X-ray
–Contrast study
SIGMOID VOLVULUS
•Simple or complicated
•Underlying diagnosis
•Acute management
•Subsequent management
•Resect or fix
Issues to consider:

SIGMOID VOLVULUS
•Immediate resuscitation
•Emergency laparotomy
•Resection of infarcted segment
•Ends out!
Colonic Infarction:
TREATMENT OF SIGMOID VOLVULUS
• Endoscopic decompression–Rigid ∑ + flatus tube
–Flexible sigmoidoscopy
–Colonoscopy
Initial Management
SIGMOIDOSCOPIC DECOMPRESSION
• 1st Described by Bruusgard 1947
• Successful in 70-90% of cases
• Beware megacolon and pseudobstruction
• Correct position of patient
• Apron + incopads!
• Well lubricated tube with side holes
• Attach bag to tube first
• Flush tube
• Recurrence rate >80%
TREATMENT OF SIGMOID VOLVULUS
• Endoscopic decompression–Rigid ∑ + flatus tube
–Flexible sigmoidoscopy
–Colonoscopy
• Laparotomy and Pexy
• Laparotomy and resection–Colostomy
–Primary anastomosis
• Percutaneous Endoscopic Colostomy• Mesosigmoidoplasty
• Laparoscopic resection
Initial Management
Definitive Management
• Age of patient
–Chronological & biological
• Physical state
• Co-morbidity
• Mental state
• Social circumstances

• Extended left hemi colectomy
• Subtotal colectomy
–Ileostomy
–Ileo-rectal anastomosis
–Caecorectal anastomosis
SURGERY FOR SIGMOID VOLVULUS
Options in presence of megacolon:
• 1st Described 1993
• Daniels et al 2000, Br.J.Surg
–14 patients, 53-99 years old
–Two point fixation
–Mean follow up 12 months
–Recurrence in 3/8 after early removal
–No recurerence in 5 where tube left in
SIGMOID VOLVULUS
Percutaneous Endoscopic Colostomy
Mesosigmoidoplasty for Volvulus
•Broadens attachment of mesentery
•No anastomosis
•Difficult to perform with oedematous or thickened mesentery
•Subrahmanyam (1992) Br J Surg–126 patients (60% emergency)–1 death–2 recurrences
• Involves caecum and ascending colon
• May resolve spontaneously
• High index of suspicion
• Laparotomy required
• Resection +/- stomas
• Caecopexy
• Caecostomy
