  • organo axial Volvulus of the small intestine radiological case report and consideration for its mechanism
    Abdominal Radiology, 2017
    Co-Authors: Toshitaka Ishiguro, Takashi Hiyama, Katsuhiro Nasu, Yoshimasa Akashi, Manabu Minami
    Abstract:

    Gastrointestinal Volvulus is mainly classified into two subtypes, mesentero-axial Volvulus and organo-axial Volvulus. The detailed imaging findings of organo-axial Volvulus of the small intestine have never been reported as far as we know. In this article, we report a case of organo-axial Volvulus of the small intestine, focusing on the computed tomography (CT) findings. An 80-year-old man was radiologically diagnosed as having organo-axial Volvulus of the terminal ileum and it was confirmed by open surgery without adhesion or any other anatomical abnormalities. CT showed two specific findings, split-bowel sign and rotating-C sign, which we think reflect pathophysiologic features of organo-axial Volvulus. We think the pathogenic mechanism of organo-axial Volvulus can be explained by the convergence of the reversed-rotational twist following the formation of a twisted but non-obstructive circular loop, even if there is no adhesion. Radiologists should be aware that organo-axial Volvulus can occur even in the small intestine, and in the case of small bowel obstruction with single transition point, the two pathophysiologic signs mentioned above must be looked for to diagnose the possibility of organo-axial Volvulus.

  • laparoscopic repair of hiatal hernia with mesenterioaxial Volvulus of the stomach
    World Journal of Gastroenterology, 2011
    Co-Authors: Kazuki Inaba, Yoichi Sakurai, Jun Isogaki, Yoshiyuki Komori, Ichiro Uyama
    Abstract:

    Although mesenterioaxial gastric Volvulus is an uncommon entity characterized by rotation at the transverse axis of the stomach, laparoscopic repair procedures have still been controversial. We reported a case of mesenterioaxial intrathoracic gastric Volvulus, which was successfully treated with laparoscopic repair of the diaphragmatic hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication. A 70-year-old Japanese woman was admitted to our hospital because of sudden onset of upper abdominal pain. An upper gastrointestinal series revealed an incarcerated intrathoracic mesenterioaxial Volvulus of the distal portion of the stomach and the duodenum. The complete laparoscopic approach was used to repair the Volvulus. The laparoscopic procedures involved the repair of the hiatal hernia using polytetrafluoroethylene mesh and Toupet fundoplication. This case highlights the feasibility and effectiveness of the laparoscopic procedure, and laparoscopic repair of the hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication may be useful for preventing postoperative recurrence of hiatal hernia, Volvulus, and gastroesophageal reflux.

  • characteristics of intestinal Volvulus and risk of mortality in malawi
    World Journal of Surgery, 2020
    Co-Authors: Laura N Purcell, Rachel Reiss, Charles Mabedi, Jared R Gallaher, Rebecca G Maine, Anthony G Charles
    Abstract:

    Intestinal Volvulus is a common cause of mechanical intestinal obstruction (MIO) in Africa. Sigmoid Volvulus has been well characterized in both high-income and low-income countries, but there is also a predilection for small bowel Volvulus in sub-Saharan Africa. An analysis was performed of the Kamuzu Central Hospital Acute Care Surgery Registry from 2013 to 2019 on patients presenting with intestinal Volvulus. Bivariate analysis was performed for covariates based on the intestinal Volvulus type. Multivariate Poisson regression models estimated the relative risk of Volvulus and mortality. A total of 4352 patients were captured in the registry. Overall, 1037 patients (23.8%) were diagnosed with MIO. Intestinal Volvulus accounted for 499 (48.1%) of patients with MIO. Sigmoid Volvulus, midgut Volvulus, ileosigmoid knotting, and cecal Volvulus accounted for 57.7% (n = 288), 19.8% (n = 99), 20.8% (n = 104), and 1.6% (n = 8), respectively. Mean age was 46.8 years (SD 17.2) with a male preponderance (n = 429, 86.0%) and 14.8% (n = 74) mortality. Overall, the most common operations performed were large bowel (n = 326, 74.4%) and small bowel (n = 76, 16.7%) resections with 18.0% (n = 90) ostomy formation. Upon regression modeling, the relative risk for Volvulus was 2.7 times higher in men than women after controlling for season and age. There was no statistically significant difference in the relative risk of mortality based on the type of Volvulus. Volvulus is a significant cause of primary bowel obstruction in sub-Saharan Africa. Type of intestinal Volvulus is not associated increased risk of mortality. Reasons for increases in the incidence of small bowel Volvulus are still largely undetermined.

  • the role of the anatomy of the sigmoid colon in developing sigmoid Volvulus a case control study
    Clinical Anatomy, 2011
    Co-Authors: Adesola Akinkuotu, Jonathan C Samuel, Nelson Msiska, Chimwemwe Mvula, Anthony G Charles
    Abstract:

    Sigmoid Volvulus is a common condition throughout much of the world. To this date, there are no adequately controlled clinical trials examining the role of anatomy in sigmoid Volvulus. Therefore, the objective of this study was to determine if the anatomic dimensions of the sigmoid colon differ in sigmoid Volvulus compared to controls. This prospective case-control study was conducted at Kamuzu Central Hospital, Lilongwe, Malawi. Cases included individuals 18 years or older with surgically confirmed sigmoid Volvulus, while controls included individuals undergoing surgery for reasons unrelated to the descending or sigmoid colon, or rectum. Intraoperative measurements of the sigmoid colon were taken, including mesosigmoid root width and mesosigmoid length. A total of 26 cases and 12 controls were enrolled. When compared to controls, the mesosigmoid of cases had a greater length and maximal width; however, mesosigmoid root width was similar between groups. These findings support the assertion that sigmoid Volvulus is due to a long and wide mesosigmoid that rotates on a constant mesosigmoid root width. This is the first adequately controlled trial examining anatomy in sigmoid Volvulus and provides strong evidence that refines prior hypotheses regarding the anatomic basis of sigmoid Volvulus.
