The reported incidence of intestinal endometriosis varies between 22% and 37%, with bowel obstruction in only 2.3% of cases, but few series report acute obstruction. We report a rare case of acute bowel obstruction due to multiple bilateral deep intestinal endometriosis lesions localised in the ileum, ileocaecal valve and upper rectum, requiring synchronous resection in an emergency setting. A 42-year-old woman was referred to our clinic with a diagnosis of obstructing Crohn’s disease based on abdominal computed tomography with oral contrast showing a thickened terminal ileum with stenosis, compression of the caecum and proximally dilated small bowel loops. Simultaneous ileocaecal resection and segmental resection of the upper rectum with handsewn end-to-end anastomosis between the sigmoid colon and rectum was performed. Owing to the advanced bowel obstruction and significant weight loss, a double barrelled ileoascendostomy was created. The patient had an uneventful recovery. Histological examination revealed transmural endometriosis with involvement of the pericolic fat in both specimens. Although intestinal endometriosis causing acute bowel obstruction is rare, it should be included among the differential diagnoses in young women with recurrent abdominal pain, intermittent diarrhoea and constipation without a family history for inflammatory bowel disease or cancer. Bleeding synchronous with menstruation is not typical for intestinal endometriosis. Right-sided intestinal endometriosis more frequently causes acute bowel obstruction, in most cases due to intussusception.

Background Primary squamous cell carcinoma of the thyroid gland (PSCTC) is a rare malignancy, but demonstrates a very aggressive behaviour and has a poor prognosis. The best treatment is radical surgery and postoperative chemo-and radiotherapy, although there are some reports that this tumour is resistant to conservative therapy. Patients often present with a large tumour mass on the neck with a solid consistency. Diagnosis is usually set during the operation -on a frozen section. Case report We present a case of a 71-year-old man with weight loss and rapidly growing neck mass for the last two months. MRI showed a tumour of the left lobe of the thyroid gland, compressing the trachea and the adjacent structures. A left thyroidectomy with isthmectomy has been performed. Frozen section showed primary squamous cell carcinoma. Tumour recurrence two months later led to the second operation with the same effect. The patient died in a couple of months. Conclusion Because of its rarity and poor biology, treatment of PSCTC remains unsatisfactory. There are still many challenges on its origin, behaviour and prognostic factors. The results of postoperative chemo-or radiotherapy are controversial.

INTRODUCTION: PMP is a rare disease with a slow but progressive course leading to death. According to the literature PMP encompass wide variety of conditions. To avoid the confusion and to facilitate the treatment and comparison of the results several authors suggested that the term "PMP" should include only the cases with appendiceal origin. CASE REPORT: We report two cases with low-grade paseudomyxoma peritonei. The first case was managed by debulking surgery alone with survival 2 years. The second case underwent complete cytoreduction plus HIPEC and 3 years later is still alive and free of disease. There was one patient with a benign appendiceal mucocele treated by appendectomy, who is free of disease 3 years later. CONCLUSION: Despite the high complication rate, cytoreductive surgery with HIPEC remains the gold standard in the treatment of pseudomyxoma peritonei. The tumor grade and completeness of cytoreduction are the main prognostic factors. Due to the rarity of the condition most of the surgeons are not experienced enough to manage these patients. Additionally, the incomplete cytoreduction is associated with poorer prognosis and significantly hampers the subsequent interventions. Thus, in the cases when it is found incidentally, the best strategy is the taking of biopsy, appendectomy and subsequent referral to a specialized center for a treatment by multidisciplinary team.

Hemobilia is an extremely rare cause of upper gastrointestinal bleeding. It often has intermittent manifestation, which may lead to significant diagnostic delay. In 65% of the cases, the causes are iatrogenic, in 7% the cause is malignancy, in 5% - gallstones, in 8% it is inflammation (cholecystitis, parasites, reflux cholangitis), vascular abnormality is the cause in 7% (most commonly pseudoaneurysm of the hepatic artery), and pancreatic pseudocyst causes hemobilia in 1%. In almost all cases, the bleeding originates from intrahepatic or extrahepatic bile ducts, and rarely from the pancreas. PUBMED search with keywords “hemobilia” and “arteriobiliary fistula” found a total of 44 papers. No case with intrapancreatic arterio-biliary fistula was found. To the best of our knowledge, we present a unique case of delayed life-threatening hemobilia caused by intrapancreatic arterio-biliary fistula. It was diagnosed at the fourth admission and managed successfully by emergency Traverso-Longmire pancreatoduodenal resection. We briefly discuss the keys to a timely diagnosis and the cornerstones of the treatment. The timely diagnosis of hemobilia depends on a high index of suspicion and careful interpretation of the symptoms. Hemodynamic stability has a crucial role in the decision-making process. Angioembolization is the cornerstone of the treatment, whereas surgery is reserved only for cases with an unstable hemodynamic or unsuccessful embolization. Surgical approach depends on the bleeding site. Although an emergency pancreatic head resection is a procedure of last resort, it can be life-saving in cases with intractable bleeding due to intrapancreatic arteriobiliary fistula.
