Review
Sigmoid volvulus is a common surgical emergency, especially in elderly patients. Patients can present with a wide range of clinical states: from asymptomatic, to frank peritonitis secondary to colonic perforation. These patients generally need urgent treatment, be it endoscopic decompression of the colon or an upfront colectomy. The World Society of Emergency Surgery united a worldwide group of international experts to review the current evidence and propose a consensus guidelines on the management of sigmoid volvulus.

Review
A wide variety of disorders affecting the intestinal tract in cattle may require surgery. Among those disorders the more common are: intestinal volvulus, jejunal hemorrhage syndrome and more recently the duodenal sigmoid flexure volvulus. Although general principles of intestinal surgery can be applied, cattle has anatomical and behavior particularities that must be known before invading the abdomen. This article focuses on surgical techniques used to optimize outcomes and discusses specific disorders of small intestine. Diagnoses and surgical techniques presented can be applied in field conditions.

Review
Volvulus describes the twisting of the intestine or colon around its mesentery. Intestinal obstruction and/or ischaemia are the most common complications of volvulus. Within the gastrointestinal tract, there is a preponderance towards colonic volvulus. The sigmoid is the most commonly affected segment, followed by the caecum, small intestine and stomach. Distinguishing between the differing anatomical locations of gastrointestinal volvulus can be challenging, but is important for the management and prognosis. This article focuses on the main anatomical sites of gastrointestinal volvulus encountered in clinical practice. The aetiology, presentation, radiological features and management options for each are discussed to highlight the key differences.

Meta-Analysis Comparative Study Review
BACKGROUND
Gangrenous sigmoid volvulus has a significant impact on morbidity and mortality. This study was conducted to compare sigmoid resection and primary anastomosis (RPA) with sigmoid resection and end colostomy (Hartmann's procedure) for gangrenous sigmoid volvulus.
METHODS
A systematic review and meta-analysis study design was employed to summarize retrospective cohort, prospective cohort, and randomised control trial studies published from inception to march 31, 2023. Searching was performed on Medline, CINAHAL, Web of Science, Google Scholar, the Cochrane Library, and ClinicalTrials.gov to locate eligible articles. Data searching, selection and screening, quality assessment of the included articles, and data extraction were done by two separate reviewers. RevMan 5.4 software with a fixed-effect Mantel-Haenszel model and Stata version 14 were used to analyze the data. The protocol registered on PROSPERO registration website (CRD42023413367).
RESULTS
Ten cohort studies and one randomised control trial with 724 patients were found; all of them were rated as being of moderate quality. The overall mortality after RPA was 15% (95%CI: 11-19%), and after Hartmann's procedure it was 19% (95%CI: 15-23%). Resection and primary anastomosis (RPA) for gangrenous sigmoid volvulus had slightly lower mortality rate than stoma (OR=0.98(95%CI: 0.68-1.42), p=0.07, I=43%), which had no statistically significant difference. Resection and primary anastomosis (RPA) had a slightly higher morbidity rate than Hartmann's procedure (OR=1.01(95%CI: 0.66-1.55), p=0.30, I=18%), which had no statistically significant difference.
CONCLUSION
Sigmoid resection and primary anastomosis (RPA) and Hartmann's procedure had no significant differences in mortality and morbidity for the treatment of gangrenous sigmoid volvulus. Choice of the intervention for gangrenous sigmoid volvulus should be individualized with consideration of different detrimental factors.

Cecal volvulus is a rare complication of malfixation anomalies and intestinal malrotation in children. Only few cases have been reported. The rarity of the condition, frequently leads to diagnostic delay and complications. The best option for cecal volvulus repair remains unclear. Our aim is to increase the awareness of surgeons about cecal volvulus and to discuss its management.

Sigmoid volvulus in paediatric patients is a rare but potentially life-threatening condition. Since 1940, only 100 cases have been reported. There are no consensual guidelines for juvenile sigmoid volvulus unlike in adults, where the condition and the treatment is well described. We report a case of a 12-year-old patient, who presented with uncharacteristic symptoms of mild abdominal discomfort and lack of passage of stool. A CT-scan showed a sigmoid volvulus and emergency resection was performed with placement of a colostomy. With this case, we want to emphasise juvenile sigmoid volvulus as a probable differential diagnosis when symptoms of abdominal distress and constipation occur.

Review
Colonic volvulus is the third leading cause of colonic obstruction worldwide, occurring at two principal locations: the sigmoid colon and cecum. In Western countries, sigmoid volvulus preferentially affects elderly men whereas cecal volvulus affects younger women. Some risk factors, such as chronic constipation, high-fiber diet, frequent use of laxatives, personal past history of laparotomy and anatomic predispositions, are common to both locations. Clinical symptomatology is non-specific, including a combination of abdominal pain, gaseous distention, and bowel obstruction. Abdominopelvic computerized tomography is currently the gold standard examination, allowing positive diagnosis as well as detection of complications. Specific management depends on the location, patient comorbidities and colonic wall viability, but treatment is an emergency in every case. If clinical or radiological signs of gravity are present, emergency surgery is mandatory, but is associated with high morbidity and mortality rates. For sigmoid volvulus without criteria of gravity, the ideal strategy is an endoscopic detorsion procedure followed, within 2 to 5 days, by surgery that includes a sigmoid colectomy with primary anastomosis. Exclusively endoscopic therapy must be reserved for patients who are at excessive risk for surgical intervention. In cecal volvulus, endoscopy has no role and surgery is the rule.

Review
Radiologists must be able to recognize the imaging signs of intestinal malrotation because this condition can lead to potentially lethal complications such as midgut volvulus. The correct diagnosis depends on both high clinical suspicion and the radiologist's ability to recognize the specific signs of malrotation and the normal variants that can lead to the wrong diagnosis. Although the location of the third portion of the duodenum outside the retroperitoneal area on ultrasonography, CT, or MRI seems to be a reliable sign of malrotation, the gold standard for determining whether the duodenojejunal flexure is in an abnormal location continues to be the upper gastrointestinal series. In this article, we review the most important imaging signs of malrotation and emphasize the role of ultrasonography in diagnosing midgut volvulus.

Observational Study
PURPOSE
To analyze the treatment outcomes for sigmoid volvulus (SV) and identify risk factors of complications and mortality.
METHODS
Observational study of all consecutive adult patients diagnosed with SV who were admitted from January 2000 to December 2020 in a tertiary university institution for conservative management, urgent or elective surgery. Primary outcomes were 30-day postoperative morbidity, mortality and 2-year overall survival (OS), including analysis of risk factors for postoperative morbidity or mortality and prognostic factors for 2-year OS.
RESULTS
A total of 92 patients were included. Conservative management was performed in 43 cases (46.7%), 27 patients (29.4%) underwent emergent surgery and 22 (23.9%) were scheduled for elective surgery. Successful decompression was achieved in 87.8% of cases, but the recurrence rate was 47.2%. Mortality rates following episodes were higher for conservative treatment than for urgent or elective surgery (37.2%, 22.2%, 9.1%, respectively; p = 0.044). ASA score > III was an independent risk factor for complications (OR = 5.570, 95% CI = 1.740-17.829, p < 0.001) and mortality (OR = 6.139, 95% CI = 2.629-14.335, p < 0.001) in the 30 days after admission. Patients who underwent elective surgery showed higher 2-year OS than those with conservative treatment (p = 0.011). Elective surgery (HR = 2.604, 95% CI = 1.185-5.714, p = 0.017) and ASA score > III (HR = 0.351, 95% CI = 0.192-0.641, p = 0.001) were independent prognostic factors for 2-year OS.
CONCLUSION
Successful endoscopic decompression can be achieved in most SV patients, but with the drawbacks of high recurrence, morbidity and mortality rates. Concurrent severe comorbidities and conservative treatment were independent prognostic factors for morbidity and survival in SV.

BACKGROUND
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.
METHODS
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.
RESULTS
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.
CONCLUSION
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.
