    Abstract A best evidence topic has been constructed using a described protocol. The three-part question addressed was: In patients undergoing laparoscopic appendicectomy is Hem-o-lok clip safer than Endoloop ligature for closure of appendiceal stump? The search has been devised and 6 studies were deemed to be suitable to answer the question. The outcome assessed was the safety and cost effectiveness of Hem-o-lok clip (Polymer ligation) versus Endoloop ligature for appendiceal stump closure during laparoscopic appendicectomy. We concluded that Hem-o-lok clip is a safe and feasible tool for appendiceal stump closure. It's also a cost-effective way and could be a cheaper option compared to other measures.

    Abstract A best evidence topic has been constructed using a described protocol. The three-part question addressed was: In [patients undergoing bariatric surgery], is [intraperitoneal local bupivacaine during the operation ] associated with [ lower pain score and decrease in post operative pain medications]? The search has been done and six randomized trial studies are considered to be appropriate to answer this question. The outcome assessed is the value of intraperitoneal bupivacaine in bariatric surgery in terms of effect on the pain score and post operative analgesia. We concluded that intraperitoneal bupivacaine causes improvement in both the pain score and post operative analgesia.

    Abstract BACKGROUND Peritoneal loose bodies, also known as peritoneal mice, are rare findings and they present either with nonspecific symptoms or are found incidentally during exploration and autopsy. Usually, they have no clinical significance and require no specific treatment. We report a case of a giant peritoneal loose body found incidentally in the abdominal cavity of a patient who presented with abdominal pain and hematuria. CASE REPORT Our patient was a 58-year-old man who presented with abdominal pain and hematuria. Abdominal non-contrast computed tomography (CT) and subsequent CT abdomen and pelvis with intravenous and oral rectal contrast were performed preoperatively, showing a well-circumscribed and calcified lesion of undetermined etiology in the abdominal cavity. The lesion was removed laparoscopically with no complications. Histopathologically, the lesion was reported as calcified tissue with fat necrosis, most likely an infarcted appendix epiploicae. CONCLUSIONS Loose peritoneal bodies can present a challenging diagnostic problem to the surgeon, with confusing findings that can point towards malignancy. It often requires a number of investigations; however even with these investigations, operative exploration, either open or laparoscopic, can be the ultimate diagnostic and therapeutic modality, and the mobility of these calcified lesions may give a preoperative clue to the etiology. It is important to distinguish peritoneal loose bodies from neoplastic or metastatic lesions and to consider it in the differential diagnosis of a calcified mobile pelvic mass. Laparoscopic surgery is safe and effective in the retrieval of symptomatic peritoneal loose bodies.

    Abstract Background: We aimed to study the prevalence and outcomes of thrombophilia in acute pulmonary embolism.
    Methods: A retrospective observational study was conducted to include patients with a radiologically confirmed diagnosis of PE screened for thrombophilia from May 2011 to February 2015. Data included patients' demographics; clinical presentation, risk factors, laboratory investigations, management, and outcome were analyzed and compared in patients with and without thrombophilia.
    Results: A total of 227 cases of PE were included in the study, of which 108 (47.6%) had thrombophilia. The most frequent coagulopathic abnormality included deficiency of protein S, protein C, and antithrombin III and hyperhomocysteinemia. Only seven out of 79 patients were found to have factor V Leiden. PE patients diagnosed with thrombophilia were 10 years younger in age and peaked in the age range 30-39 years. Prior history of DVT (
    Conclusion: Deficiencies of protein S, protein C, and antithrombin III are the leading causes of thrombophilic defects. Patients with hereditary thrombophilia are at increased risk of acute PE, particularly among young individuals. Therefore, early detection of thrombophilic defects together with other unprovoked risk factors could reduce the risk of recurrent VTE.

    Abstract Background: Acute Appendicitis (AA) is the most common abdominal surgical emergency. It requires proper management to decrease mortality and morbidity. Clinical scoring systems for diagnosing AA aimed to decrease the use of radiological scans and the rate of negative appendectomies (NA). We aim to assess the adult appendicitis score (AAS) in the diagnosis prediction of AA.
    Method: A retrospective study with 1303 cases of AA is performed. We compared the correlation of AAS and Alvarado scores to postoperative histopathology. Specificity, sensitivity, Positive Predictive Value (PPV), and Negative Predictive Value (NPV) were assessed. ROC was used.
    Results: AAS risk stratification was applied to the study population. Group I for a low probability, and groups II and III for an intermediate and high probability of AA. We found that 159 patients were matched in group I, 505, and 639 were in groups II and III of AAS, respectively. The correlation between Alvarado and AAS with HP was significant. AAS ≥ 16 presented sensitivity and specificity of 50 % and 75.47 %, respectively, with PPV of 97.96 % and NPV of 6.02 %, with an accuracy of 51.04 %. Regarding AAS ≥ 11, the sensitivity was 88.96 %, specificity was 39.62 %, PPV was 97.2 %, NPV was 13.21 %, and accuracy was 86.95 %.
    Conclusion: AAS is relatively more accurate than Alvarado's score, especially in selecting a safe candidate for discharge from an emergency. In addition, AAS is found to decrease the need for radiological images and NA rate more than Alvarado.

    Abstract Introduction: Amyand's hernia (AH) is rare, schistosomiasis of the appendix is very uncommon, and both conditions coexisting together is an extremely rare event. Pre-operative diagnosis of each of the two conditions is usually difficult. To the best of our knowledge, the current paper is first to report both these two conditions in coexistence.
    Presentation of case: A 31-year old man who had no comorbidities was admitted electively as a day case of non-complicated right indirect inguinal hernia. Further history and physical examination were unremarkable. Intraoperatively the patient was found to have right sliding AH with appendicular schistosomiasis (AS). The patient underwent Lichtenstein repair of the hernia with appendectomy. On follow up he was referred to infectious disease clinic, and the post-operative course was uneventful.
    Conclusions: Intraoperative identification of non-typical hernia sac before its opening should alert the surgeon to the possibility of sliding hernia and the presence of an organ as a part of the sac. Rare causes of appendicular masses like schistosomiasis granuloma should be considered in endemic areas or immigrants from these areas, despite the difficulty of preoperative diagnosis. Management should follow general guidelines of appendectomy, hernia repair and dealing with the associated pathology if present.
