A rare diaphragmatic hernia with a delayed presentation of intestinal symptoms following spleno-distal pancreatectomy: a case report

Acquired diaphragmatic hernia, non-related to trauma, is a very rare condition. It can constitute a therapeutic problem and the surgical solution is not always immediately clear. We report the case of a 73-year-old woman with a history of spleno-distal pancreatectomy for a neuroendocrine tumour performed in 2009, who came back to Emergency Room 2 years later, complaining of abdominal pain. Chest radiography and computed tomography were performed; they showed a diaphragmatic hernia with visceral migration into the thorax. The diaphragmatic defect was surgically repaired and the patient had an uneventful post-operative recovery

Targeting protein kinase C by Enzastaurin restrains proliferation and secretion in human pancreatic endocrine tumors

Dysregulation of the protein kinase C (PKC) signaling pathway has been implicated in tumor progression. In this study, we investigate the effects of a PKC inhibitor, Enzastaurin, in human pancreatic neuroendocrine neoplasms (PNN) primary cultures and in the human pancreatic endocrine cancer cell line, BON1. To this aim six human PNN dispersed in primary cultures and BON1 cells were treated without or with 1–10 μM Enzastaurin and/or 100 nM IGF1 in the presence or absence of serum. Cell viability and apoptosis were evaluated after 48–72 h; Chromogranin A (CgA) and/or insulin secretion was assessed after 6 h of incubation. PKC expression was investigated by immunofluorescence and western blot. We found that Enzastaurin significantly reduced human PNN primary culture cell viability, as well as CgA and insulin secretion. Moreover, in the BON1 cell line Enzastaurin inhibited cell proliferation at 5 and 10 μM by inducing caspase-mediated apoptosis, and reduced phosphorylation of glycogen synthetase kinase 3β (GSK3β) and of Akt, both downstream targets of PKC pathway and pharmacodynamic markers for Enzastaurin. In addition, Enzastaurin blocked the stimulatory effect of IGF1 on cell proliferation, and reduced CgA expression and secretion in BON1 cells. Two different PKC isoforms are expressed at different levels and have partially different subcellular localization in BON1 cells. In conclusion, Enzastaurin reduces cell proliferation by inducing apoptosis, with a mechanism likely involving GSK3β signaling, and inhibits secretory activity in PNNin vitromodels, suggesting that Enzastaurin might represent a possible medical treatment of human PNN

How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons

COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p < 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p < 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p < 0.0001) or urgent (20.4% vs. 38.5%; p < 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p < 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice

Voluminous abdominal gastrointestinal stromal tumor of unknown origin manifested with bleeding in a young man: synchronous management of the emergency and oncological approach-case report

Gastrointestinal stromal tumors (GISTs) are rare tumors of the gastrointestinal tract, which cover about 1-2% of gastrointestinal neoplasms with an unadjusted incidence of around 1/100,000/year. They are also the most common non-epithelial neoplasms of the gastrointestinal tract and they are associated with a high rate of malignant transformation. They are more common in the stomach (40-60%) while a minor part repeatedly involves jejunum/ileus (25-30%), duodenum (5%), colorectal (5-15%) and esophagus (<1%). There are also much rarer extragastrointestinal stromal tumor (EGIST): these tumors have immunohistochemical and molecular characteristics similar to GISTs and for this reason, they are called this way, EGIST can involve retroperitoneum, mesentery, and omentum, without affecting the gastrointestinal tract. The clinical presentation depends on the primary localization of the neoplasm, however in 18% it is asymptomatic, and it is accidentally discovered during endoscopies, radiological examinations or surgical operations performed for other reasons, especially if it is small in size. More often, they are associated with non-specific symptoms such as early satiety, nausea or vomiting. Gastrointestinal bleeding is the most dangerous complication, often necessitating emergency surgery. The purpose of this case report is to describe our experience in the management of a young patient with gastrointestinal bleeding caused by an unknown voluminous retroperitoneal GIST with metastatic progression using a combined endovascular embolization and debulking-surgery approach for emergency and imatinib therapy combined with radiofrequency for the oncological approach. GIST requires multidisciplinary management, which improves both prognosis and quality of life

Mechanical hepaticojejunostomy: can we use a circular stapler as a viable and safe alternative? —a retrospective study of a single center

Background: Since the first years of the 1980s, some authors described the use of mechanical stapler for the creation of anastomosis in biliary surgery. However, the use of these devices has not spread during the following decades, and nowadays most centers usually craft hand-sewn anastomosis. Methods: We retrospectively collected data from medical records, surgical registries and computerized databases about the use of mechanical circular staplers for the creation of hepaticojejunostomy at our institution. Results: From 2012 to 2020, 11 stapled hepaticojejunostomy for both neoplastic and non-neoplastic diseases were performed at our institution. The mean age of the patient was 74, with a sex distribution of 5 men and 6 women. The mean preoperative common bile duct diameter was 19 mm. Preoperative blood samples showed mean total bilirubin of 6.95 mg/dL. No intraoperative complications were reported. Two patients (18%) had minor postoperative complications (1 wound dehiscence and 1 episode of melena that required blood transfusions), while no major complications occurred. No patients developed biliary fistula or anastomotic dehiscence. No one dies within 30 days from surgery. The mean postoperative length of stay was 13 days. Conclusions: According to our limited experience, stapled hepaticojejunostomy seems to be a safe and effective technique in selected patients

Ovarian stimulation and liver dysfunction: Is a clinical relationship possible? A case of hepatic failure after repeated cycles of ovarian stimulation

Liver damage induced by ovarian stimulation has been demonstrated in some cases reported in the literature. However, there has never been a fruitful debate on this topic. The present manuscript tried to fill this gap. We reported a case of a 35-year-old nulliparous woman admitted to our obstetric emergency room for severe pre-eclampsia. She had been subjected to four cycles of controlled ovarian stimulation for intrauterine insemination. At 32 weeks of gestation, she developed severe pre-eclampsia, which led to HELLP syndrome complicated by fatal liver failure. The etiological link between ovarian stimulation and HELLP syndrome is intriguing. Further investigations are needed to understand whether repeated ovarian stimulation may represent a risk factor in pre-eclamptic patients. © 2013. The Korean Society for Reproductive Medicine
