Colonic perforation due to impacted faeces or faecaloma is a relatively uncommon presentation with grave prognosis. If left untreated, it can be life threatening due to complications like faecal peritonitis. Till date, fewer than 150 cases have been reported mostly in the English surgical literature describing constipation as the most common underlying etiology. Involvement of rectum is rare with very limited data published in this context. We present a case of stercoral perforation involving the rectum with associated faecal peritonitis and pneumatosis coli.

Gas within the portal circulation has been known to be associated with a number of conditions most commonly mesenteric ischemia and necrosis. Systemic venous gas is described with few conditions and is mostly iatrogenic in nature. We describe a case of combined portal and systemic venous gas detected by computed tomography in a patient with perforated duodenal ulcer.

Fetal ovarian cysts are the most common abdominal masses in the female fetuses and believed to be caused by in utero exposure of fetus to maternal and placental hormones. Majority of them are diagnosed in third trimester and should be distinguished from other causes of abdominal masses of genitourinary and gastrointestinal origin. Once diagnosed serial ultrasound monitoring is recommended to document changes in size or appearance. Complications like torsion or rupture merit careful assessment and surgical intervention to preserve ovarian function and fertility. We report a case of intrauterine ovarian dermoid cyst complicated by torsion, which was diagnosed prenatally on ultrasound as complex cystic lesion within the abdomen.

Background and aim Diabetic patients with foot ulcer and peripheral ischemia were shown to be associated with hypercoagulation and dysfunction in the fibrinolytic system that in turn would affect the healing of the ulcer. The authors aimed to investigate the role of rivaroxaban in improving the microcirculation of the skin and peripheral tissues and how it can improve ischemic diabetic foot ulcers. Patient and methods The authors conducted an observational retrospective case–control study at Al-Azhar University Hospital, New Damietta, from January 2015 till December 2020. Diabetic patients with foot ulcer and peripheral limb ischemia who received rivaroxaban till ulcer healing were considered as the case group, whereas patients who did not receive rivaroxaban were considered as the control group. Clinical assessment and pulse oximeter were used for the assessment of transcutaneous microcirculation. Results Throughout the 5 years of the study, 172 patients were included; the case group included 87 patients and the control group included 85 patients. There was a significant difference between the two groups regarding the improvement of limb ischemia, tissue plasminogen activator antigen, and transcutaneous microcirculation (P<0.05). Before the treatment, there was a significant correlation between both permeability coefficient and plasma fibrinogen and transcutaneous microcirculation. Conclusion The oxygenation of the ulcer and the microcirculation were found to be improved in the case group and accelerate wound healing in the ischemic diabetic foot.
