Schistosomiasis is an infectious disease caused by parasitic flatworms of the genus Schistosoma. The species Schistosoma mansoni is associated with hepatosplenic disease. Schistosomiasis involving the gallbladder alone is highly unusual, with a few cases reported. Herein, we present the case of a woman from a region with endemic schistosomiasis who presented with a painless solid lesion and wall thickening of the gallbladder. She underwent an uneventful laparoscopic cholecystectomy. Microscopic examination of the surgical specimen revealed Schistosoma mansoni eggs associated with granulomatous reaction, leading to the diagnosis of schistosomiasis of the gallbladder, prompting subsequent treatment with praziquantel and follow-up. This case illustrates the importance of suspicion for this diagnosis in endemic areas, as it can be misdiagnosed with malignancy if not examined microscopically. Complications and treatment strategies are poorly characterized for the few cases of schistosomiasis; reporting this case can serve as a helpful reminder of a rare presentation of this disease., Competing Interests: Conflict of interest: The authors have no conflict of interest to declare., (Copyright: © 2024 The Authors.)

Background: The unresectable pancreatic head tumors develop obstructive jaundice and cholestasis during follow-up. Cholestasis is associated with complications and treatment options are endoscopic stenting (ES) and biliary bypass surgery (BBS)., Aims: The aim of the current study was to compare the safety and efficacy of biliary bypass surgery (BBS) and endoscopic stenting (ES) for cholestasis in advanced pancreas cancer., Methods: This is a retrospective cohort of patients with cholestasis and unresectable or metastatic pancreas cancer, treated with BBS or ES. Short and long-term outcomes were evaluated. We considered the need for hospital readmission due to biliary complications as treatment failure., Results: A total of 93 patients (BBS=43; ES=50) were included in the study. BBS was associated with a higher demand for postoperative intensive care (37 vs.10%; p=0.002, p<0.050), longer intensive care unit stay (1.44 standard deviation±2.47 vs. 0.66±2.24 days; p=0.004, p<0.050), and longer length of hospital stay (7.95±2.99 vs. 4.29±5.50 days; p<0.001, p<0.050). BBS had a higher risk for procedure-related complications (23 vs. 8%; p=0.049, p<0.050). There was no difference in overall survival between BBS and ES (p=0.089, p>0.050). ES was independently associated with a higher risk for treatment failure than BBS on multivariate analysis (hazard ratio 3.97; p=0.009, p<0.050)., Conclusions: BBS is associated with longer efficacy than ES for treating cholestasis in advanced pancreatic cancer. However, the BBS is associated with prolonged intensive care unit and hospital stays and higher demand for intensive care.

Bariatric patients are at risk for developing biliary stones. Choledocholithiasis poses a significant challenge in Roux-en-Y gastric bypass patients due to anatomical changes, complicating the treatment. We present a case of a 71-year-old female with recurrent choledocholithiasis post-bariatric surgery. After failed endoscopic attempts, a biliodigestive bypass with choledocoduodenal anastomosis was performed successfully using the Da Vinci robotic platform. This technique offers a single anastomosis, excluding the duodenum from transit, preventing food reflux. The patient had an uneventful recovery with no recurrence after 1 year. The choledocoduodenal anastomosis is a viable option for biliary diversion in patients with challenging endoscopic access post-gastric bypass, offering favorable outcomes., (© 2024.

Background: Minimally invasive distal pancreatectomy (MIDP) is associated with less blood loss and faster functional recovery. However, the benefits of robotic assisted distal pancreatectomy (RDP) over laparoscopic distal pancreatectomy (LDP) are unknown., Aims: To compare RDP versus LDP for surgical treatment of benign lesions, pre-malignant and borderline malignant pancreatic neoplasias., Methods: This is a retrospective study comparing LDP with RDP. Main outcomes were overall morbidity and overall costs. Secondary outcomes were pancreatic fistula (PF), infectious complications, readmission, operative time (OT) and length of hospital stay (LOS)., Results: Thirty patients submitted to LDP and 29 submitted to RDP were included in the study. There was no difference regarding preoperative characteristics. There was no difference regarding overall complications (RDP - 72,4% versus LDP - 80%, p=0,49). Costs were superior for patients submitted to RDP (RDP=US$ 6,688 versus LDP=US$ 6,149, p=0,02), mostly due to higher costs of surgical materials (RDP=US$ 2,364 versus LDP=1,421, p=0,00005). Twenty-one patients submitted to RDP and 24 to LDP developed pancreatic fistula (PF), but only 4 RDP and 7 LDP experienced infectious complications associated with PF. OT (RDP=224 min. versus LDP=213 min., p=0.36) was similar, as well as conversion to open procedure (1 RDP and 2 LDP)., Conclusions: The postoperative morbidity of robotic distal pancreatectomy is comparable to laparoscopic distal pancreatectomy. However, the costs of robotic distal pancreatectomy are slightly higher.

This article addresses the question of the Muslim umma (the universal community of Muslims) which arises within the context of the ongoing debates about the status of refugees and their rights around the world, especially in the Muslim world, where a significant majority of migrants and refugees originate and are hosted. We question the existence of the Muslim umma under contemporary circumstances and discuss the extent to which the modern nation-state has undermined the principles of Muslim unity and solidarity beyond national borders. We also examine how Islamic ethics and law ( fiqh ) identify the imperatives of providing comfort and protection for refugees (whether they are Muslim or non-Muslim) individuals, groups, and communities when required or requested. We see this in principle, but not always in practice. Are refugee policies applied by Muslim-majority countries today in accordance with the fundamental Islamic teachings and experiences of the original hijra ? Or have such principles been made redundant by the political-geographic imperatives of ethnicized nation-states? To what extent can applied policies in Muslim-majority countries be developed and enhanced in the light of umma principles that might alleviate the longstanding refugee crises in this troubled area of the world? The article consists of three main sections. The first provides a theoretical and religious analysis of the idea of the umma as an inclusive entity that encompasses all Muslims, contrasted with the modern nation-state as an exclusive geographically defined political institution. The second looks at three Muslim-majority countries that played a significant hosting role in refugee crises over the past decade, namely Jordan, Bangladesh, and Turkey. We offer some insight in understanding to what extent their policies or behavior were based upon ummatic principles, or secularist notions of national interest and humanitarian aid? The last section summarizes the recent innovation providing for Muslim refugees through a UNHCR arrangement and adaptation with the Islamic charitable obligation of Zakat . It is suggested that the UNHCR Zakat Fund is an ummatic manifestation that has already proved honorable and viable. The conclusion calls for a better understanding of the umma as it is in the Islamic consciousness towards an effective reforming of refugee policies and practices, suggesting a further enhancement of ummatic institutional collaboration between the OIC and UNHCR for refugee integration., Competing Interests: Competing interestsBoth authors declare that they have no competing interests., (© The Author(s) 2022.)

Background: The incidence of small nonfunctioning neuroendocrine pancreatic tumors (NF-PNETs) has been increasing systematically in the last few decades. Surgical resection was once considered the treatment of choice but has been questioned in the direction of a more conservative approach for selected patients. Our aim was to analyze the outcome of surgical resection of small (≤3cm) NF-PNETs., Methods: We retrospectively evaluated 14 patients with sporadic NF-PNETs who underwent pancreatic resection. Data were collected from patients' medical records., Results: Of the 14 patients included, 35.71% were men, and the average age was 52.36 ± 20.36 years. Comorbidities were present in 92.86% of the cases. The incidence of postoperative complications was 42.86%, the 30-day mortality was zero, and the length of follow-up was 3.31 ± 3.0 years. The results of pathological evaluations revealed WHO grade I in 42.86% of cases, II in 21.43%, and neuroendocrine carcinoma in 35.71%. The median tumor size was 1.85cm (range, 0.5-3cm), and 2 cases had synchronous metastasis. The median TNM stage was IIa (range, I-IV). The disease-free and patient survival rates were 87.5% and 100% at 3 years and 43.75% and 75% at 10 years, respectively. The tumor pathological grade was significantly higher in head tumors than body-tail tumors, but there were no differences with respect to tumor size and TNM staging., Conclusion: A surgical approach to treat small sporadic NF-PNETs is safe with low mortality and high patient survival. Based on these data, small pancreatic head tumors can be more aggressive, suggesting that surgical resection is still the best option to treat small nonfunctioning PNETS. Thus, conservative treatment should be indicated very cautiously for only cases with absolute contraindications for surgery., Competing Interests: The authors declare that they have no conflict of interest., (Copyright © 2021 Estela Regina Ramos Figueira et al.)

Lipomas of the gastrointestinal tract are uncommon benign tumors of mature adipocytes and may occur in any portion along the gut. Depending on location they may have a variety of clinical presentations and even simulate malignant neoplasms. We report a case of a 58-year-old woman who presented with acute pelvic pain. An emergency sonogram detected a hyperechogenic mass in the left adnexal region, with no vascularization on Doppler. A computed tomography confirmed the hypothesis of a fat containing tumor with signals of torsion. The patient underwent laparoscopy which depicted a mass over the antimesenteric side of the sigmoid with signs of ischemia and twisted vascular pedicle. The lesion was resected, and the microscopy confirmed the diagnosis of lipoma. The multidisciplinary team in the emergency room must be aware of these possible complications in order to optimize patient care.

Background: Due to rising life expectancy of population, very complex surgical procedures such as pancreaticoduodenectomy (PD), are more commonly being performed in elderly patients. The objective of this study was to evaluate the safety of PD in patients older than 75 years old and the risk factors associated with severe complications., Methods: Patients who underwent PD for periampullary tumors were retrospectively reviewed and divided into two groups, A (<75 years) and B (>75 years). The primary endpoint was severe postoperative complications (Clavien 3 or greater). Secondary endpoints were mortality and any complications., Results: Ninety consecutive patients underwent PD for periampullary tumors in the studied period, 70 in group A and 20 in group B. Clinical and pathological characteristics of both groups were equivalents except for age. There were no difference regarding the incidence of severe complications (17% vs. 10%, P=0.72) or all complications (50% vs. 50%, P>0.999). Although mortality was greater in group A (8.6% vs. 0%), it was not statistically significant (P=0.333). On multivariate analyses, only male sex, obesity and American Society of Anesthesiology Score of 3 or 4 were associated with severe postoperative complications., Conclusions: Poor clinical status, obesity and male gender are associated with severe complications in PD, but not age greater than 75 years, therefore PD can be considered safe in elderly patients and age itself should not be a contraindication for PD., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Objective: To evaluate the prognostic significance of microvessel density and p53 expression in pancreatic cancer., Methods: Between 2008 and 2012, 49 patients with pancreatic adenocarcinoma underwent resection with curative intention. The resected specimens were immunohistochemically stained with anti-p53 and anti-CD34 antibodies. Microvessel density was assessed by counting vessels within ten areas of each tumoral section a highpower microscope., Results: The microvessel density ranged from 21.2 to 54.2 vessels/mm2. Positive nuclear staining for p53 was found in 20 patients (40.6%). The overall median survival rate after resection was 24.1 months and there were no differences in survival rates related to microvessel density or p53 positivity. Microvessel density was associated with tumor diameter greater than 3.0 cm and with R0 resection failure., Conclusions: Microvessel density was associated with R1 resection and with larger tumors. p53 expression was not correlated with intratumoral microvessel density in pancreatic adenocarcinoma.

Background: Solid pseudopapillary pancreatic neoplasia is usually a large well-circumscribed pancreatic mass, with cystic and solid areas more frequently found in young women. It is a benign pancreatic neoplasia in most cases, therefore minimally invasive surgery could be an interesting approach., Aim: Evaluate the results of minimally invasive surgery for this neoplasia., Methods: Patients with this tumor who underwent minimally invasive pancreatectomies between 2009 and 2015 in a single institution, were analyzed regarding demographic, clinical-pathological futures, post-operative morbidity and disease-free survival., Results: All were women, and their median age was 39 (18-54) years. Two patients with tumor in the head of the pancreas underwent laparoscopic pancreaticoduodenectomy, and another one underwent laparoscopic enucleation. Two patients with tumor in the neck underwent central pancreatectomy. Distal pancreatectomies were performed in the other five, one with splenic preservation. None required blood transfusion or conversion to open surgery. Two (20%) developed clinical relevant pancreatic fistulas, requiring readmission. Median length of postoperative hospital stay was five days (2-8). All resection margins were negative. Patients were followed for a median of 38 months (14-71), and there was no recurrence., Conclusions: Minimally invasive surgery for solid pseudopapillary pancreatic neoplasia is feasible for tumors in different locations in the pancreas. It was associated with acceptable morbidity and respected the oncologic principles for treatment.
