Laceration of the transverse mesocolon in an old man with a habit of abdominal massage for constipation: a case report

Background Abdominal massage for the resolution of constipation has been reported to be safe and recommended in some studies. It is conventionally performed for the elderly suffering from intractable constipation. Meantime, isolated mesenteric injury after blunt abdominal trauma is uncommon. Here, we report a case of isolated mesenteric injury following self-abdominal massage for constipation. Case presentation A 68-year-old man consulted a local hospital due to a sudden abdominal pain. He had a history of prostate cancer treated with radiation therapy 3 years ago, and he had been suffering from chronic constipation for many years. A plain computed tomography (CT) revealed a fist-sized homogeneous mass-like lesion located in the left upper abdomen and a moderate amount of ascites. With the initial diagnosis of a malignant tumor accompanied by peritonitis carcinomatosa, he was hospitalized for further examinations. On the next day, his hemoglobin concentration dropped from 11.6 to 6.6 g/dl, and diagnostic paracentesis showed bloody ascites. He was urgently transferred to our tertiary emergency center. An enhanced CT demonstrated a non-enhanced, homogeneous, 8.5 cm in diameter, mass lesion located to the posterior of the stomach with massive bloody ascites. He underwent an emergency exploratory laparotomy, and it showed a 5 cm of laceration in the transverse mesocolon adjacent to Treitz’s ligament and approximately 1.5 l of intraabdominal hemorrhage. Hemostasis of the bleeding from the laceration was achieved by suture ligations, but the gap of the laceration could not be closed by suturing because the tissue was too fragile. Blood transfusion with 4 units of packed red blood cells and 10 units of fresh frozen plasma was performed during operation. He was discharged without any significant complications except for postoperative paralytic ileus. Later on, it turned out that he had a habit of massaging his abdomen for the resolution of intractable constipation and did it hard 1 day before the onset. Conclusions This is the first report of life-threatening mesenteric injury caused by self-abdominal massage to resolve constipation, though other etiologies such as rupture of small aneurysms could not perfectly be excluded. Abdominal massage is reported to be effective and safe for the resolution of constipation; however, this case demonstrated it could be detrimental.

Right-sided omental torsion with inguinal hernia

A 38 year old man was admitted to our hospital with abdominal pain. He had an untreated right inguinal hernia and the hernia presented as a swelling ball of 4.0×3.0 cm in size. CT showed a large mass of fat density below the Sigmoid colon and incarcerated fat within the right inguinal hernia. Emergent laparotomy revealed four-circle twisted and infarcted greater omentum and a little bloody ascites within the right inguinal hernia. Pathological examination showed hemorrhagic infarction of the greater omentum. Although omental torsion is a rare cause of acute abdominal pain, it should be taken into consideration in the differential diagnoses of acute abdomen, especially in patients with untreated inguinal hernia.

Encapsulating peritoneal sclerosis presenting with haemorrhagic ascites after transfer from peritoneal dialysis to haemodialysis

A patient with end-stage kidney disease due to chronic glomerulonephritis was initiated on continuous ambulatoryperitoneal dialysis. After three years he was transferred to haemodialysis following recurrent episodes of peritonitis. After the commencement of haemodialysis the patient developed progressive abdominal distension; paracentesisrevealed bloody ascites. Radiographic imaging revealed features of small bowel obstruction with bowel loops matted tothe posterior abdominal wall. A diagnosis of encapsulating peritoneal sclerosis was made. Treatment with prednisonewas initiated but the patients condition steadily worsened and he demised a year later due to severe malnutrition andsepsis.
