Mesenteric ischemia following intestinal infarction caused by occlusion of the superior mesenteric artery is a rare and devastating disease. The overall mortality is a high as 80%. The purpose of this prospective study was to investigate erythrocyte flux to defined areas of the intestine immediately after laparotomy by using laser Doppler flowmetry (LDF) assessment. We tried to predict the intestinal viability and recovery of the small bowel, and further tried to define the level of critical…

Venous Small Bowel Infarction: Intraoperative Laser Doppler Flowmetry Discriminates Critical Blood Supply and Spares Bowel Length

TLDR
Laser doppler flowmetry and spectrometry are potentially powerful methods to assist the surgeon's decision-making in critical venous mesenteric perfusion, thus having an important impact on clinical outcome.

Prospects of Intraoperative Multimodal OCT Application in Patients with Acute Mesenteric Ischemia

TLDR
The study finds that MM OCT visualized the damage to serosa, muscularis externa, and blood vessels localized in these layers in 100% of AMI cases, and the MM OCT diagnostic procedure optimally meets the requirements of emergency surgery.

Acute mesenteric ischemia after cardiopulmonary bypass surgery

Acute mesenteric ischemia (AMI) is a highly-lethal surgical emergency. Several pathophysiologic events (arterial obstruction, venous thrombosis and diffuse vasospasm) lead to a sudden decrease in

Infrared imaging contribution for intestinal ischemia detection in wound healing.

TLDR
It has been possible studying thermal variations through infrared image in rats, showing correlation between thermal response in thermograms, ischemic time and histopathological findings.

Machine learning for intraoperative prediction of viability in ischemic small intestine

TLDR
Intraoperative bioimpedance measurements on intestine of suspect viability combined with machine learning can increase the accuracy of intraoperative assessment of intestinal viability and has the potential to reduce the high mortality and morbidity rate of the patients.

Assessment of Ischemic Small Intestine using Bioimpedance Measurements

TLDR
The time development of the electrical properties measured within a 6 hr period of ischemia is statistically significant, and can be correlated with the onset and duration of ischemic time.

Mesenteric ischemia: still a deadly puzzle for the medical community.

The main goal of this article is to update etiology, epidemiology, diagnosis, treatment and outcome of the various causes of mesenteric ischemia in order to elucidate its labyrinthine clinical

Intraoperative Determination of Small Intestinal Viability following Ischemic Injury: A Prospective, Controlled Trial of Two Adjuvant Methods (Doppler and Fluorescein) Compared with Standard Clinical Judgment

TLDR
Fluorescein fluorescent pattern was correct in all 54 determinant bowel segments, and proved more sensitive specific, predictive, and significantly more accurate overall than either standard clinical judgment or the Doppler method.

Acute mesenteric ischemia

TLDR
Acute mesenteric ischemia is becoming an increasing cause of death in old patients with generalized atherosclerosis, and the recent advances in medical imaging and minute flowmetry make it possible to detect intestinal lesions and the state of visceral perfusion, transcutaneously in the early stage of the disease.

The rationale for "second-look operation" in mesenteric vessel occlusion with uncertain intestinal viability at primary surgery.

TLDR
Although the data do not permit firm recommendations, use of second-look operation in patients with doubtful viability of the intestine may reduce the extent of resection at primary exploration and also the incidence of insufficient anastomosis.

The role of second-look procedure in improving survival time for patients with mesenteric venous thrombosis.

TLDR
Since 1978, 21 patients (12 men and nine women) suffering from mesenteric venous thrombosis (MVT) were treated at the Hadassah University Medical Center, and the role of second-look procedures in improving survival time is outlined.

Acute mesenteric ischaemia.

TLDR
It is concluded that early diagnosis is critical for successful management of acute mesenteric ischaemia, but outcome is also influenced by the aetiology.

Differential alterations in microvascular perfusion in various organs during early and late sepsis.

TLDR
The microvascular responses in the fluid-resuscitated sepsis model are characterized by hyperperfusions in the early stage and hypoperfusion in the late stage of sepsi in the tested tissues.

Measurement of colonic blood flow with laser Doppler flowmetry.

TLDR
It is concluded that laser Doppler flowmetry represents a potentially very interesting non-invasive, continuous method for the quantitative study of human intestinal blood flow.

Continuous measurement of intestinal mucosal blood flow by laser-Doppler velocimetry.

TLDR
Observations indicate that the laser-Doppler technique measures blood flow in the surface tissue and does not reflect blood flow throughout the other tissues of the bowel wall.
