Nontraumatic Retroperitoneal Hematoma After Warfarin Administration: Fatal Case Report and Review of the Literature.

Spontaneous retroperitoneal hematoma after warfarin therapy is an extremely rare event. Here, we report a 25-year-old man who was brought in to the emergency service with confusion. On arrival, the patient had hypotension, tachycardia, tachypnea, low-grade fever, and Glasgow Coma Scale score of 12. Abdominal examination revealed distention and mild tenderness in the right upper quadrant of the abdomen. The patient had a history of aortic valve replacement surgery and was on warfarin treatment at an international normalized ratio of 2.4. Our patient progressed to cardiorespiratory arrest. The resuscitation was initiated promptly. Despite all resuscitation measures, including transfusion and administration of high doses of catecholamine, the patient died of hypovolemic shock 3 hours after admission. At autopsy, the external surface of the abdominal great vessels (descending aorta and mesenteric vessels) showed scattered petechial hemorrhages without any visible site of perforation. After comprehensive exploration of the abdomen, no evidence of traumatic event was identified and the cause of internal blood loss was noted as warfarin adverse effect.

A Delayed Presentation of Perforated Diffuse Large B Cell Lymphoma of the Small Bowel Resulting in a Large Interloop Faecaloma.

Primary small bowel lymphomas are a rare entity but with significant morbidity and a low five-year overall survival even after surgery. Its diagnosis is often delayed due to the lack of clear specific signs, unfamiliarity amongst clinicians, and the lack of screening tools. This often results in patients presenting with tumour-associated complications such as perforation, obstruction, or gastrointestinal bleeding which warrant urgent surgical intervention. We present the case of a patient presenting with a perforated small bowel lymphoma resulting in a large interloop extraluminal faecaloma causing subacute small bowel obstruction. He proceeded to have an emergency open right hemicolectomy and extended small bowel resection to facilitate gross resection of tumour which in conjunction with adjuvant systemic chemotherapy is considered current best practice to manage such neoplasms. Early referral to specialist centres and raising awareness of this rare entity will allow earlier recognition and therefore a more planned approach to the management of such pathology with fewer post-operative complications.

A case report of ectopic pancreatic tissue in the gallbladder.

Heterotropic pancreatic tissue is a rare entity where aberrant pancreatic tissue is located without any anatomical connection to the pancreas. It is usually reported to be found in stomach, duodenum, jejunum and spleen. Rare locations include lung, mediastinum, liver, mesentery, ileum, meckels diverticulum and gallbladder [1, 2]. This anomaly is often an incidental finding during laparotomy or autopsy. We describe a case of an elective laparoscopic cholecystectomy with the histology of the gallbladder showing focal ectopic pancreatic acinar tissue.

Perforation of the Meckel's diverticulum with a chicken bone: a case report and literature review.

BACKGROUND: Meckel's diverticulum (MD) is the most common congenital abnormality of the gastrointestinal (GI) tract. Most of the people remain asymptomatic during their lifetime, but some can develop complications such as inflammation, haemorrhage or obstruction. Perforation of Meckel's diverticulum is very rare, and we present a case of perforation by a chicken bone. CASE PRESENTATION: A 19-year-old man presented to the emergency department with abdominal pain, and based on examination and laboratory findings, he was diagnosed with appendicitis initially. Meanwhile, a CT scan was requested and a foreign object inside the Meckel's diverticulum was noted, and on further questioning, he mentioned that he had chicken with bones 2 days ago. He was taken to the operating theatre, and during laparotomy, the perforated Meckel's diverticulum was found, and it was resected with primary anastomosis. CONCLUSION: Meckel's diverticulum follows the 'rule of twos', and perforation of it with foreign object is rare. Patients usually present with signs and symptoms of acute abdomen, and appendicitis is the first diagnosis, and the final diagnosis is usually made intraoperatively. Perforation of Meckel's diverticulum should be considered for the patients who present with acute abdomen, and with precise history taking and investigations, preoperative diagnosis can be achieved.

A rare presentation of appendicitis inside the femoral canal: case report and literature review.

BACKGROUND: Femoral hernia accounts for 3% of all the hernias, and in 0.5-5% of cases, the appendix can migrate through the femoral hernia and is called de Garengeot hernia. It is a very rare condition, and the incidence of appendicitis in this type of hernia is as low as 0.08-0.13%. CASE PRESENTATION: We bring into discussion a case of a 47-year-old female who presented to the emergency department with a painful right-sided groin lump for the past 2 days. After initial resuscitation, a CT scan was requested which showed the presence of inflamed appendix inside the femoral canal. She was taken to the operative theatre, and during the laparoscopy, the appendix was identified migrating through the femoral canal and it could not be retracted into the peritoneal cavity; therefore, the mesoappendix was divided and the operation converted to the open low approach. After identifying the femoral hernia sac and opening it, the appendix was removed and herniorrhaphy was performed. Our patient had an uneventful recovery and was discharged on the following day. CONCLUSION: We report a rare case of de Garengeot hernia which was diagnosed preoperatively. Because of its non-specific presentation, patients are usually diagnosed with incarcerated femoral hernia and are taken to operative theatre and the final diagnosis is made intra-operatively. Due to its rarity, there is no standard approach for this condition, and emergency appendicectomy and concurrent herniorrhaphy is the mainstay of treatment. In this paper, we present different surgical methods for the treatment of this type of hernia.
