A 20-Year-Old Gossypiboma Causing Small Bowel Obstruction.

Retained foreign bodies including gossypiboma could be silent for years. However, in some cases, it can lead to major complications. Gossypiboma is not frequently reported for multiple reasons, including nonspecific presentation clinically and radiologically, and ethical issues. We present a case of a gossypiboma that was retained for more than 20 years causing a severe intestinal obstruction for an elderly female. The intestinal obstruction was initially thought to be adhesive in nature and was managed initially conservatively, but with failure to improve, the patient was taken for exploratory laparotomy, and the foreign body was found attached to the root of the mesentery posterior to the transverse colon. This case sheds light on the fact that although surgical tools are of great utility, they must be managed with utmost care to prevent complications and secure patients' safety.

Peritoneal Tuberculosis in a Young Healthy Male Resembling Intra-Abdominal Malignancy.

Intra-peritoneal tuberculosis is a rare disease, accounting for 1-2% of all tuberculosis cases. The absence of characteristic clinical picture of intra-peritoneal tuberculosis makes the diagnosis rarely easy for clinicians as it mimics malignancy. We present a case of a young male patient who presented with peritoneal tuberculosis, aiming to contribute to a better understanding of peritoneal tuberculosis in the literature.

Outcomes of staged hepatectomies for liver malignancy.

Liver malignancies are the fifth most common cause of death worldwide. Surgical intervention with curative intent is the treatment of choice for liver tumors as it provides long-term survival. However, only 20% of patients with metastatic liver lesions can be managed by curative liver resection. In most of the cases, hepatectomy is not feasible because of insufficient future liver remnant (FLR). Two-stage hepatectomy is advocated to achieve liver resection in a patient who is considered to not be a candidate for resection. Procedures of staged hepatectomy include conventional two-stage hepatectomy, portal vein embolization, and associating liver partition and portal vein ligation for a staged hepatectomy. Technical success is high for each of these procedures but variable between them. All the procedures have been reported as being effective in achieving a satisfactory FLR and completing the second-stage resection. Moreover, the overall survival and disease-free survival rates have improved significantly for patients who were otherwise considered nonresectable; yet, an increase in the morbidity and mortality rates has been observed. We suggest that this type of procedure should be carried out in high-flow centers and through a multidisciplinary approach. An experienced surgeon is key to the success of those interventions.

Focal liver lesions found incidentally.

Incidentally found focal liver lesions are a common finding and a reason for referral to hepatobiliary service. They are often discovered in patients with history of liver cirrhosis, colorectal cancer, incidentally during work up for abdominal pain or in a trauma setting. Specific points should considered during history taking such as risk factors of liver cirrhosis; hepatitis, alcohol consumption, substance exposure or use of oral contraceptive pills and metabolic syndromes. Full blood count, liver function test and tumor markers can act as a guide to minimize the differential diagnosis and to categorize the degree of liver disease. Imaging should start with B-mode ultrasound. If available, contrast enhanced ultrasound is a feasible, safe, cost effective option and increases the ability to reach a diagnosis. Contrast enhanced computed tomography should be considered next. It is more accurate in diagnosis and better to study anatomy for possible operation. Contrast enhanced magnetic resonance is the gold standard with the highest sensitivity. If doubt still remains, the options are biopsy or surgical excision.

Anticoagulation and antiplatelets as prophylaxis for hepatic artery thrombosis after liver transplantation.

Hepatic artery thrombosis (HAT) is the most serious vascular complication after liver transplantation. Multiple risk factors have been identified to impact its development. Changes in haemostasis associated with end stage liver disease and the disturbance of the coagulation and anticoagulation cascades play an important role in development of this lethal complication. Early recognition and therapeutic intervention is mandatory to avoid its consequences. Pharmacological prophylaxis, by the use of antiplatelet or anticoagulant agents, is an important tool to reduce its incidence and prevent graft loss. Only a few studies have shown a clear benefit of antiplatelet agents in reducing HAT occurrence, however, these studies are limited by being retrospective and by inhomogeneous populations. The use of anticoagulants such as heparin is associated with an improvement in the outcomes mainly when used for a high-risk patients like living related liver recipients. The major concern when using these agents is the tendency to increase bleeding complications in a setting of already unstable haemostasis. Hence, monitoring of their administration and careful selection of patients to be treated are of great importance. Well-designed clinical studies are still needed to further explore their effects and to formulate proper protocols that can be implemented safely.
