We present a case of sigmoid volvulus in a young male patient with culture-proven Salmonella Typhi in the blood which was sensitive to Meropenem and Azithromycin only, presented with fever, vomiting, loose stools, hematochezia, abdominal distention and tenderness with no signs of perforation on erect chest x-ray. Further, radiological imaging showed signs of sigmoid volvulus. An urgent colonic decompression with untwisting of the mesentery was performed. Read More

A 52-year-old man whose fecal occult blood test was positive was found to have type 2 sigmoid colon cancer by colonoscopy. On enhanced barium enema study, the cecum was in the pelvis, and the ascending colon was running medially in the abdomen. Enhanced CT scan of the abdomen revealed rotation of the superior mesenteric vein(SMV). Read More

Ileosigmoid knotting (ISK) is the wrapping of the ileum or sigmoid colon around the base of the other structure, causing a double-loop intestinal obstruction. The disease generally presents as an intestinal obstruction with volvulus triad, including abdominal pain/tenderness, distention, and obstipation. Abdominal X-ray findings are not pathognomonic, and computerized tomography (CT) and magnetic resonance imaging (MRI) are more useful in the diagnosis. Read More

BACKGROUND Appendicitis is the most common cause of abdominal pain requiring emergent surgical intervention. Although typically presenting as right lower-quadrant pain, in rare cases it may present as left upper-quadrant pain secondary to abnormal position due to intestinal malrotation. Since atypical presentations may result in diagnostic and management delay, increasing morbidity and mortality, accurate and prompt diagnosis is important. Read More

Sigmoid volvulus is an extremely rare cause of abdominal pain in children. More commonly seen in older adults, an SV occurs when a redundant loop of sigmoid wraps around its elongated, narrow mesentery causing obstruction and ischemia to the affected bowel segment. Children usually present with abdominal pain, nausea, and abdominal distension. Read More

Introduction: Ultrasound examinations during pregnancy are routine procedures used to detect fetal congenital malformations. Ultrasound monitoring of sigmoid colon mesenterial development could be useful for early detection of subjects at risk of sigmoid colon volvulus.

Objective: The aim of our paper was to assess the sigmoid colon length, and sigmoid colon mesentery width and height in the late fetal period, and, using the results, to estimate the surface area of the mesocolon (in mm) in living fetuses. Read More

Chilaiditi's sign is an anatomical alteration consisting of the transposition of the small intestine or colon between the liver and diaphragm that is asymptomatic and is usually an accidental radiological finding. The onset of Chilaiditi syndrome is accompanied by clinical symptoms and is even rarer. Moreover, the combination of sigmoid volvulus and Chilaiditi syndrome is extremely rare, with only 17 previous published cases, one of which occurred in a female patient. Read More

Background: Sigmoid volvulus is frequently reported in the "volvulus belt" (Middle East, Africa, the Indian subcontinent, Turkey, and South America) and is the third leading cause of large bowel obstruction in North America. It is an uncommon problem in children and adolescents, and is rarely considered a diagnosis in this group. A high index of suspicion is necessary to diagnose sigmoid volvulus in children. Read More

The utility and limitations of abdominal ultrasonography (US) were retrospectively evaluated as a first-line diagnostic imaging modality in patients with abdominal pain. Hospital records from patients subjected to abdominal US as a first-line diagnostic imaging examination at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) from April 2010 to April 2015 were analyzed. Only those patients who underwent abdominal US to diagnose abdominal symptoms were included in the present study. Read More

Background: Colonic obstruction is a relatively common condition in emergency care, with a mortality rate of up to 20%. In 90% of cases it results from colonic or rectal adenocarcinoma, volvulus, or stenosis secondary to diverticular disease. When fecal impaction is the underlying cause, the condition is usually managed conservatively, but may on occasion become complicated and even require surgical intervention. Read More

Synchronous colorectal cancers refer to the simultaneous occurrence of multiple colorectal tumors in a single patient, excluding any metastases from other organs. At present, radical surgery is considered the standard curative treatment; however, individualized surgical strategies depend on tumor location, the depth of invasion and the general health of the patient. In the present study, the case of a 52-year-old man who presented with a 2-month history of abdominal pain that was accompanied by intermittent hematochezia and weight loss is reported. Read More

Postmortem radiography is useful for visualizing the body prior to autopsy. We discuss postmortem multidetector computed tomography that was tailored for optimum image quality to allow reconstruction of the fatal findings in multiple axes and in three dimensions, helping to pinpoint the anatomical sites of interest.

Colonic volvulus involving the caecum and splenic flexure of the colon is an extremely rare surgical entity and, as a result, it is rarely entertained as a differential diagnosis for large bowel obstruction. The most common site of volvulus is located at the sigmoid colon (75%) followed by caecum (22%). Rare sites of colonic volvulus include the transverse colon (about 2%) and splenic flexure (1-2%).
