Seed bezoars are a subcategory of phytobezoars, caused by consumption of indigestible vegetable or fruit seeds. We present the case of a 64-year-old male patient, who presented at the Emergency Department, complaining of constipation, tenesmus and rectal pain. History and digital examination revealed a rectal seed bezoar due to sunflower seeds, impacted in the lower rectum. The patient underwent manual disimpaction under general anaesthesia, after conservative measures failed. Seed bezoars represent a different pathophysiological process compared to fibre bezoars. They are usually found in the rectum of patients without predisposing factors, causing constipation and anorectal pain. History taking and digital rectal examination are the cornerstones of diagnosis, with manual disimpaction under general anaesthesia being the procedure of choice., Competing Interests: The authors declare no competing interests.

Introduction: Enterobius vermicularis or "pinworm" infection of the liver is an extremely rare condition with only five cases previously reported in literature. It is characterized by the presence of granulomas in the liver with a necrotic core, containing adult helminthes or their ova. Because of the relatively mild symptomatology associated with this disease, prior to the arrival of modern imaging methods hepatic enterobiasis was an incidental intra-operative finding during abdominal surgery for other conditions. In recent years however, with high-resolution abdominal imaging readily available and the improved safety of hepatic resection, a lower threshold for treating suspicious hepatic nodules aggressively with surgery is being adopted., Presentation of Case: We present the second case in international literature, where E. vermicularis of the liver was mistaken for malignancy and led to hepatic resection and perform a literature review of the five previously documented cases of hepatic enterobiasis., Discussion: Our report identifies certain trends in this condition's aetiology and clinical behaviour, but due to its rarity definitive answers cannot yet be established., Conclusion: We do not advocate a change in the current approach of suspicious hepatic nodules, but we do feel that better understanding of the mechanisms involved with hepatic enterobiasis could, in the future, prevent unnecessary surgery.

Introduction: Hemipelvectomies are uncommon operations, usually performed for primary or metastatic malignant disease and less frequently for benign-aggressive tumours. There are very few reports in literature regarding complications of these procedures and even fewer reports about post hemipelvectomy hernias in particular., Presentation of Case: We present the only reported case of an incisional hernia of the urinary bladder following internal hemipelvectomy for aneurysmal bone cyst of the pubic bone. A careful literature review is also performed., Discussion: The development of the incisional hernia in the case of our patient can most likely be explained by the absence of advanced malignant disease of the pelvis that not only reduces the life expectancy but also overshadows other complications post hemipelvectomy. Furthermore, her young age and level of fitness allowed for a full postoperative rehabilitation which, combined with the proven anatomical changes of the internal organs following hemipelvectomies and the weakening of the tissues around the operative site, predisposed to the hernia formation., Conclusion: Hemipelvectomies are extensive, anatomically disruptive operations, with significant detriment to the psychosomatic well being of the patients. We presented the only reported case of incisional hernia of the urinary bladder following internal hemipelvectomy and our reconstructive method of choice. We believe that, in the case of our patient, if a mesh had been used to reconstruct the primary defect during the initial surgery, this complication could have been prevented., (Copyright © 2012 Surgical Associates Ltd.

Multivisceral surgical resection for cure was successfully performed in a 70-year-old man suffering from a primary hepatocellular carcinoma (HCC) associated with direct invasion to the stomach and pancreas. The patient presented with gastric outlet obstruction, upper abdominal pain and a history of chronic liver disease due to hepatitis B virus (HBV) infection. Upper gastrointestinal (GI) endoscopy revealed an infiltrating tumor protruding through the gastric wall and obliterating the lumen. Computer tomograghy (CT) and magnetic resonance imaging (MRI) scan demonstrated a 15-cm tumor in the left lateral segment of the liver with invasion to the stomach and pancreas. Alpha-foetoprotein (AFP) levels and liver function tests were normal. The patient underwent an en bloc left hepatectomy, total gastrectomy, distal pancreatectomy with splenectomy and radical lymphadenectomy. Pathology revealed a poorly differentiated, giant cell HCC involving the stomach and pancreas. Disease-free margins of resection were achieved. The patient's postoperative course was uneventful. Sixteen months after surgery, he has no recurrence or distal metastasis. Direct invasion of HCC into the GI tract is rarely encountered. Complete surgical resection should be considered in selected patients with an appropriate hepatic functional reserve.
