Volvulus of the sigmoid colon is rare in children. An early, accurate diagnosis can avoid unnecessary surgery and reduce the risk of complications. This condition is mainly due to a redundant sigmoid colon with a narrow mesosigmoid attachment. We describe two cases of sigmoid volvulus, which showed different clinical severities and were treated with different methods. Patient 1, a 9-year-old boy, presented with acute abdominal pain and vomiting. Patient 2, an 11-year-old boy, presented with abdominal pain, abdominal distention, and bloody mucoid stool. Plain abdominal radiographs revealed a distended colonic loop extending upward from the pelvis in patient 1 and a typical "coffee bean" sign in patient 2. Barium enema examination was used to confirm the diagnosis in both cases. The volvulus was reduced by insertion of a rectal tube in patient 1 and surgically in patient 2. Sigmoid colon volvulus should be included in the differential diagnosis of childhood abdominal pain or distention. This report suggests that nonsurgical reduction should be attempted first for uncompromised sigmoid volvulus in children, unless bowel ischemia or perforation develops.

This retrospective descriptive study of Sigmoid colon perforation by ingested Sandorica seed in patients who were admitted to Prachomklao Hospital from 1996 to 2000. Nine cases were included in this study. Most cases were elderly with a mean age of 65 years (range 52-78 years). The main symptoms were abdominal pain with generalized peritonitis and severe tenderness at the suprapubic area, ileus and persistent vomiting. In all cases, the diagnosis was made at operation, with removal of the Sandorica seed, closure of the perforation at the rectosigmoid colon with simple suture and proximal transverse loop colostomy. Post-operative complications included two cases of wound infection.

We report a case of surgically proved left-sided torsion of the greater omentum that caused secondary by untreated inguinal hernia. Case A 36-year-old man presented to our hospital with abdominal pain. He had been diagnosed with a left inguinal hernia, but he had not received any treatments. Contrast-enhanced computed tomography (CT) of the abdomen showed a large fat density mass below the Sigmoid colon and left inguinal hernia with incarcerated fat. Exploratory laparotomy revealed torsion of the greater omentum with small bloody ascites. The greater omentum was twisted into one and a half circles and entered into a left inguinal hernia. An omentectomy with a repair of left inguinal hernia was performed. A resected omentum was submitted for pathological examination, which showed hemorrhagic infarction. Omental torsion is a rare cause of acute abdominal pain but should be included in the differential diagnoses of acute abdomen, especially in patients with untreated inguinal hernia.

Sigmoid colon diverticulosis is commonly seen in both the surgical outpatient and emergency departments. Rarely, these sigmoid diverticulum, which usually range from 2-3mm to 2cm in size, can enlarge to more than 10 times. This is due to a ball-valve type mechanism that traps colonic gas inside the sigmoid diverticulum causing it to gradually enlarge. Patients with a giant sigmoid diverticulum (GSD) must be investigated thoroughly as two per cent of patients will present with a colonic carcinoma either within or distal to the GSD. Clinical symptoms of a GSD can range from chronic abdominal pain, altered bowel habits, abdominal distention, weight loss, bleeding, perforation, fistula formation, or bowel obstruction. CT and plain abdominal x-ray is the investigation of choice for its diagnosis. Barium enema is useful to determine the presence of a carcinoma within the GSD. Sigmoidoscopy is useful to rule out a distal colonic carcinoma. This is the first published case where nocturnal diarrhoea is the primary differentiating symptom in the patient. The treatment of choice for a GSD is complete resection of the diverticulum and/or the adjacent sigmoid colon. This can be performed with a primary anastomosis or a double-stage procedure.

Takotsubo cardiomyopathy (TTC) is a stress-related cardiomyopathy that is characterized by reversible left systolic dysfunction, which appears to be precipitated by sudden emotional or physical stress in the absence of myocardial infarction. Here we present a rare case that clinically presented with intermittent abdominal pain, initially impressed as non-ST elevation myocardial infarction and congestive heart failure but with a normal coronary angiogram. Her symptoms relieved spontaneously without returning. Sigmoid colon cancer was diagnosed via colonoscopy later due to persistent abdominal discomfort. In the absence of detectable emotional or physical stress factors, the newly diagnosed sigmoid colon cancer was the only possible trigger factor of TTC. We offer this case as a reminder that cancer should be considered in the differential diagnosis of patients presenting with the etiology of TTC.

We report a case of a 48-year-old female patient, who presented with abdominal pain, jaundice, and lack of appetite. Ultrasound showed intrahepatic biliary dilatation with retroperitoneal lymphadenopathy. Further magnetic resonance cholangiopancreatography detected Klatskin tumor. Computed tomography (CT) confirmed the Klatskin tumor with liver metastases and retroperitoneal lymphadenopathy. Biopsy from the hepatic lesion identified mucinous adenocarcinoma, likely originating from bile ducts. Endoscopic retrograde cholangiopancreatography was performed 3 times with stents placed in the left and right hepatic bile ducts. Later the patient had hematochezia and was referred to colonoscopy. Tubulovillous adenoma with dysplasia was diagnosed with signs of in situ cancer. Preoperative CT was done for further staging: new pulmonary metastases were discovered. Sigmoid colon was resected. Histopathology verified a poorly differentiated mucinous adenocarcinoma within the tubulovillous adenoma. Intraoperative biopsies of porta hepatis mass resembled metastatic lymph nodes in hepatoduodenal ligament, mimicking Klatskin tumor. Retrospective analysis of CT data demonstrated presence of sigmoid colon tumor.
