Abstract
Sigmoid volvulus (SV), the wrapping of the sigmoid colon around itself, is a rare colonic obstruction form. SV requires emergency endoscopic or surgical treatment following an urgent resuscitation and the prognosis is relatively poor. Although many different classifications have been made for SV in the past, the unique classification system, which assists the decision making in the management in addition to the estimation of the prognosis, was described in 2017. Thereafter, a great number of relevant subjects were discussed in the literature. The aim of this study is to update the present classification system in light of above-mentioned discussions and our experience with 1,028 SV patients, which is the largest single-centre SV series over the world.
Highlights
Sigmoid volvulus (SV) is the wrapping of the sigmoid colon around itself causing a colonic obstruction
I reviewed the clinical records of 1,028 SV patients retrospectively until June 1986 and prospectively thereafter
Life expectancy varies from a country to another and it is generally higher in developed countries
Summary
Sigmoid volvulus (SV) is the wrapping of the sigmoid colon around itself causing a colonic obstruction. I reviewed the clinical records of 1,028 SV patients retrospectively until June 1986 and prospectively thereafter. This study was approved by the Institutional Ethics Committee Non-operative treatment was used in 750 patients (77.9%) with 82.7% success, 0.7% mortality, 2.3% morbidity, and 5.5%. 476 (46.3%) were treated by emergency surgery with 16.8% mortality, 34.2% morbidity, and 0.6% early recurrence rates. Elective surgical treatment was used in 114 of endoscopically decompressed 584 patients (19.5%) with 0.0% mortality, 11.4% morbidity, and 0.0% early recurrence rates
