Acute mechanical small bowel obstruction is a common [[surgical emergency]] where volvulus is the cause in 10% of cases. It is estimated that over 300,000 [[Laparotomy|laparotomies]] are performed per year in the United States for adhesion-related obstructions such as volvulus. Volvulus originating in the colon is the third most common cause of large bowel obstruction.

==Neonatal and Infantile volvulus==


Rotational anomalies occur as a result of an arrest of normal rotation of the embryonic gut. Because rotational anomalies may remain asymptomatic throughout a person’s life span, the true incidence is not known. Nonrotation, a type of malrotation is an incidental finding on approximately 2 out of 1000 upper gastrointestinal contrast studies [1]. Symptomatic malrotation in neonates occurs with a frequency of about 1 in 6000 live births.
Traditionally, intestinal malrotation has been considered primarily a disease of infancy with infrequent occurrence beyond the first year of life [2,3]. However, analysis of 2744 cases of intestinal rotation in children up to 17 years of age obtained from a national hospital discharge database found the following [2]:
●Presentation by one month of age: 30 percent
●Presentation before one year of age: 58 percent
●Presentation before five years of age: 75 percent
Similarly, in a series of 170 patients of all ages with symptomatic intestinal malrotation managed at a single institution, age distribution at time of presentation was as follows [3]:
●Infants under one year of age: 31 percent
●Children 1 to 18 years of age: 21 percent
●Adults over 18 years of age: 48 percent
Thus, the prevalence of malrotation in children over one year of age and adults appears to be higher than previously thought.
Associated congenital defects — Up to 62 percent of children who have intestinal malrotation have an associated anomaly (table 1) [4-7].
Based upon a systematic review of small, single-institution studies, the following conditions have demonstrated a strong association with intestinal malrotation [8]:
●Congenital diaphragmatic hernia – Up to 100 percent
●Congenital heart disease, especially heterotaxy syndrome – 40 to 90 percent (see 'Screening' below)
●Omphalocele – 31 to 45 percent
Intestinal malrotation is also associated with:
●Gastroschisis (see "Gastroschisis", section on 'Associated anomalies and findings')
●Prune belly syndrome (see "Prune-belly syndrome", section on 'Abdominal wall and gastrointestinal tract')
●Certain types of intestinal atresias [9] (see "Intestinal atresia")
●Esophageal atresia (solitary and with tracheoesophageal fistula) [10]
●Biliary atresia in patients with laterality malformations (see "Biliary atresia", section on 'Types of biliary atresia')
●Meckel diverticulum [11]
●Complex anorectal malformations or anorectal malformations with 2 or more anomalies of the VACTERL (vertebral, anal, cardiac, tracheoesophageal, renal, limb) complex [12,13]
●Cornelia de Lange syndrome [14]

Overview

Acute mechanical small bowel obstruction is a common surgical emergency where volvulus is the cause in 10% of cases. It is estimated that over 300,000 laparotomies are performed per year in the United States for adhesion-related obstructions such as volvulus. Volvulus originating in the colon is the third most common cause of large bowel obstruction.

Epidemiology and Demographics

Incidence

  • The incidence of volvulus is approximately 2 per 100,000 individuals worldwide.[1][2][3][4][5]
  • Sigmoid volvulus has the highest incidence, followed by cecal volvulus.
  • The incidence of cecal volvulus increases per year, whereas the incidence of sigmoid volvulus remains stable.
  • The incidence of volvulus is higher in those that live in nursing homes or are institutionalized. These patients usually take psychotropic drugs that interfere with colonic motility and can increase the incidence of volvulus.
  • The incidence of gastric volvulus is rare.

Prevalence

  • In 2002 - 2010, the prevalence of colonic volvulus is estimated to be 63,749 cases in the United States annually.[4]

Case-fatality rate/Mortality rate

  • The mortality rate of volvulus is 7 per 100 cases.[3]

Age

  • The incidence of volvulus increases with age; the median age at diagnosis is 70 years.[4][6][5]
  • Sigmoid volvulus has been reported in children and adolescents and is usually associated with abnormal colonic peristalsis.
  • Gastric volvulus is rare and the incidence peaks after the fifth decade.
  • The incidence of neonatal and infantile volvulus is unknown since non-rotation or malrotation of the gut may remain asymptomatic throughout life.[7]
    • In the United States, non-rotation is an incidental finding in 2 out of 1000 upper gastrointestinal contrast studies.
    • In the United States, symptomatic malrotation in neonates occurs in 1 in 6000 live births.

Race

  • Volvulus usually affects individuals of the Black race.[8][9]
    • Black individuals are at increased risk for volvulus because they tend to have a longer mesentery and sigmoid colon.

Gender

  • Most studies have found that volvulus affects men and women equally.[10][11][12]
  • Although some studies have found a predominance in men, cecal volvulus has been found to be more prevalent in younger females.

Region

  • The majority of volvulus cases are reported in Russia, India, Iran, Norway and Africa.[3]
  • In the United States, volvulus only accounts for 0.1 of cases with intestinal obstruction.
