Stress-related massive gastrointestinal bleeding in a diabetic and obese woman following double leg amputation.

Foot ulceration is a leading cause of hospital admission for patients with diabetes mellitus and the main reason for major amputation. This study presents the rare association of double amputation of both legs within 16 months of each other, a rarer outcome of diabetic foot ulcer disease, and the fatal complication of massive stress-related gastrointestinal bleeding that occurred thereafter leading to haemorrhagic shock and sudden death. On an index patient the clinical management was reviewed, a detailed autopsy performed after demise, and an extensive literature review including MEDLINE searches were carried out. Autopsy study revealed 3 ulcers in the gastric body and 1 in the gastric antrum measuring between 0.5 and 1cm and associated with about 2.5 litres of clotted blood in the gastrointestinal lumen extending from the stomach to the sigmoid colon. The patient combined physical stress factors for gastric ulceration which include uncontrolled diabetes mellitus prior to amputation, massive trauma from lower limb amputation with delayed wound healing, intake of non-steroidal anti-inflammatory drugs in the setting of past medical history of successfully treated peptic ulcer disease and the emotional stress factor of depressive illness related to the loss of her second lower limb. This association has not been reported in literature and with this we wish to warn clinicians to look out for this fatal complication in managing patients with advanced diabetic foot ulcer disease especially those going for a second limb amputation

Familial adenomatous polyposis with synchronous invasive colonic carcinomas and metastatic jejunal adenocarcinoma in a Nigerian male

Familial adenomatous polyposis is rare. Three cases were previously reported in Nigeria. An intriguing feature of this case is an ulcerated jejunal carcinoma which was metastatic rather than synchronous carcinoma. This patient presented with partial large bowel obstruction and the pathological analysis revealed 4 invasive adenocarcinomas, 3 in the colon and 1 in the jejunum (Dukes stage D). Palliative pancolectomy and jejunal tumour resection with chemotherapy was offered to him. He died eight months after surgery from disease progression. The challenges of managing a hereditary cancer syndrome in a resource poor country are highlighted

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.
