Pleural Effusion as a Negative Prognostic Factor in Patients with Acute Pancreatitis and COVID-19.

We conducted a retrospective multicentre study to investigate the association between acute pancreatitis, COVID-19, and pleural effusion. The study involved a total of 433 patients. Among them, 405 patients did not have COVID-19 infection, while 28 patients had both acute pancreatitis and COVID-19. Out of the 28 patients with both conditions, 12 also had pleural effusion. Among the 405 patients with acute pancreatitis without COVID-19, 48 had pleural effusion. The results showed that the relative risk of death associated with pleural effusion was approximately 4 times higher in patients with COVID-19 and pleural effusion compared to those with pleural effusion without COVID-19.

Hepatectomy During the Pandemic, a Curative Treatment in High-Grade and/or Hemodynamically Unstable Blunt Liver Trauma.

The liver is among the most affected organs in the case of abdominal trauma. In the last decades there have been significant changes in therapeutic protocols, non-operative management is now the first intention in most cases due to good results offered previously. In high-grade or hemodynamically unstable injuries, hepatectomy is the best approach, even though this was viewed with skepticism in the past, technical advances in medicine have proven otherwise. This article presents a case report of a 29-year-old man with blunt abdominal trauma, who initially underwent conservative atypical right hepatectomy without a favourable outcome, later he was transferred to a liver transplant center where he underwent a controlled right hepatectomy, all this in a new epidemiological context, the COVID-19 Pandemic. We want to present the hypothesis that in making a therapeutic decision, the hemodynamic status of the patient must be considered equally along with the injury degree. This case represents an opportunity to review the role of liver resection in the management of complex liver injuries.

Effect of the COVID­19 pandemic on the management and outcomes of patients with traumatic injuries (Review).

During the COVID-19 pandemic, ~10% of the global population was officially affected, resulting in diverse changes, ranging from shopping habits to stringent hospital protocols. This article sought to provide a concise summary of relevant data concerning the interplay between COVID-19 and trauma, encompassing the entire trajectory from presentation to hospital discharge. Throughout the pandemic, there was a noticeable reduction in trauma presentations, while the ranking of injury mechanisms remained largely unchanged. To ensure essential surgical support, protocols were adjusted accordingly. Although there were some less significant changes in injury severity score, hospital length of stay, intensive care unit stay and mortality, the overall patient outcomes appeared to improve. In conclusion, the COVID-19 pandemic led to a decline in trauma cases and an enhancement in patient outcomes. However, regrettably, certain mechanisms of injury saw an increase in frequency. To cope with the epidemiological context, management strategies were adapted, and unutilized resources were redirected to cater to the care of COVID-19 patients.

The Impact of the COVID-19 Pandemic on Outcomes in Acute Pancreatitis: A Propensity Score Matched Study Comparing before and during the Pandemic.

We aimed to evaluate the outcomes and survival of patients with acute pancreatitis who shared the same clinical form, age, and sex before the pandemic, during the pandemic, and among those with confirmed COVID-19 infection upon hospital admission. This consideration used the sparse data in the existing literature on the influence of the pandemic and COVID-19 infection on patients with acute pancreatitis. To accomplish this, we conducted a multicentric, retrospective case-control study using propensity score matching with a 2:1 match of 28 patients with SARS-CoV-2 infection and acute pancreatitis, with 56 patients with acute pancreatitis pre-pandemic, and 56 patients with acute pancreatitis during the pandemic. The study outcome demonstrated a six-fold relative risk of death in patients with acute pancreatitis and SARS-CoV-2 infection compared to those with acute pancreatitis before the pandemic. Furthermore, restrictive measures implemented during the pandemic period led to a partial delay in the care of patients with acute pancreatitis, which likely resulted in an impairment of their immune state. This, in certain circumstances, resulted in a restriction of surgical treatment indications, leading to a three-fold relative risk of death in patients with acute pancreatitis during the pandemic compared to those with acute pancreatitis before the pandemic.

Neutrophil/Lymphocyte Ratio as Predictor of Anastomotic Leak after Gastric Cancer Surgery.

INTRODUCTION: Neutrophil/lymphocyte ratio (NLR) is known as a prognostic for the outcome of the patients with gastric cancer. As no definite risk marker for anastomotic leakage after gastric resection was identified, we investigated the possible role of NLR. METHODS: Peripheral blood count for neutrophils and lymphocytes was done at the patient's admission. We retrospectively evaluated 204 gastric cancer patients, who underwent gastric resection, comparing the values of NLR between the group of patients with anastomotic leakage and those without complications. RESULTS: Using the ROC curve, we found the cutoff value of NLR, which permitted the comparison of the group with low NLR, presenting increased NLR. The cutoff value for NLR was 3.54. Between the two groups, we could observe statistically significant differences in developing fistula (p < 0.01) and complications leading to death (p < 0.025). The odds ratio for patients with NLR greater than 3.54 to develop anastomotic leak was 17.62, compared to those with lower NLR. CONCLUSION: Peripheral blood NLR proved to be a predictor for anastomotic leakage.

Population preferences for sources that offers information about dietary fibres health effects - an international cross-sectional survey.

OBJECTIVE: To investigate the perceived importance of information about dietary fibre with regard top opulation socio - demographic characteristics and consumption patterns. METHODS: The cross-sectional study was conducted from September to November, 2016, in six different counties and 57 cities across Romania, and was part of a larger project that had nine other countries as well. Data of the Romanian subjects was collected using a validated questionnaire that was disseminated across the 10 countries at the same time. Knowledge about dietary fibre was explored through 10 questions, and the respondents were asked to answer on a 5-point Likert scale varying from 1 (totally disagree) to 5 (totally agree). SPSS 22 was used for data anaylsis. RESULTS: Of the 670 subjects, 358 (53.4%) were females, and the overall mean age was 35.81±15.61 years (range: 18-89 years). There were 298 (44.5%) subjects with a university degree, 314(46.9%) had completed high school and 57 (8.5%) had done primary school. Besides, 568 (84.8%) participants lived in an urban environment. Internet was the main source of getting information for 368(54.9%) subjects, while the lowest was hospitals 122 (18.2%). The percentage of correct answers regarding knowledge about health effects of dietary fibre was 23.12%. Most accurate answers were related to deficiency of vitamins and minerals 370 (55.5%), breast cancer 202(30.3%), vision problems 202(30.3%) and diabetes 168 (25.2%). The question with least accurate answer was the one about general preventive characteristics of dietary fibres 65 (9.7%). CONCLUSION: A proper and friendly way to transmit information about the importance of dietary fibre consumption is critical in promoting healthy diet patterns and in preventing non-transmissible diseases.

A Rare Case of Walled-off Pancreatic Necrosis Complicated by Splenic Artery Rupture Manifested After Surgical Internal Drainage - Diagnostic and Therapeutic Aspects.

Large walled-off pancreatic necrosis (WON) is a well-known complication of severe acute pancreatitis, and it is associated with significant morbidity and mortality. This is the case report of a rare and potentially fatal complication of WON - a delayed splenic artery rupture close to its origin after surgical drainage. A 44-year old male patient admitted in our Surgical Department and diagnosed with WON evolving without infection for 6 months, after an episode of acute pancreatitis, underwent a Rouxen- Y WON-jejunostomy. In the 4th postoperative day patient presented melenic stools and a selective celiac trunk angiography was performed with the suspicion of a bleeding from the WON. At the initial injection of contrast a small leakage of contrast was observed but did not reappear despite repeated injection. The procedure was aborted, and the patient put under close observation. The 6th postoperative day bleeding re-occurred, and the angiography indicated a breach in the splenic artery. As the patient developed hemodynamic instability in the Radiology Department he was immediately transferred into the operating room and an exploratory laparotomy with suture of the splenic artery was performed. The patient had an uneventful recovery and at one-year follow-up was without any particular problems.

The morphological profile of small bowel tumors - our experience.

AIM: The authors assessed the morphological profile of tumor masses belonging to the small bowel discovered in their daily practice. MATERIALS AND METHODS: 31 tumor masses located in different segments of small intestine operated between 2002 and 2013 in the 1st Surgical Department, Emergency County Hospital of Craiova, Romania, were analyzed. The investigated parameters were: tumor location and number, tumor dimensions, gross assessment, tumor extension and histological assessment. RESULTS: Tumor masses belonging to small intestine were rare. They usually expressed by their complications. In many cases, they were placed at the extremities of the small intestine. They were usually small but sometimes large and developing outwards intestinal wall. Commonly they had a fungating and ulcerated appearance. They were rather of mesenchymal origin than epithelial. However, some of them were inflammatory pseudotumors. Almost all neoplastic proliferations had a malignant phenotype, most often with regional extension. CONCLUSIONS: Our series of tumors had a morphological profile somehow similar with the profile described in the literature but with some particularities: the polarization to the extremities of the intestinal segment, a significant number of large tumors, clinical expression through different complications, the balance inclined in favor of mesenchymal origin of tumors and the clear predominance of malignant aggressive phenotype.

Pitfalls in diagnosing a pancreatic neuroendocrine tumor: a case report.

Pancreatic neuroendocrine tumors are a rare subset of pancreatic neoplasms. We report the case of a 33-year-old female patient who was admitted to the Diabetes Clinic of Craiova, Romania, due to a two-year history of episodic neuroglycopenic hyperinsulinemic hypoglycemic symptoms, suggestive for insulinoma associated with facial and upper trunk flushing characteristic to carcinoid syndrome. During these episodes, the laboratory investigations showed hypoglycemia (38 mg/dL), hyperinsulinemia (54.72 µU/mL) and normal values of beta-hydroxybutyrate, chromogranin A, serotonin, anti-insulin antibodies and urinary levels of 5-hydroxyindoleacetic acid. Endoscopic ultrasound with SonoVue and 3T MRI revealed an 18.3/16.3 mm hypervascular tissular mass situated in the uncinate process of the pancreatic head in close contact with the superior mesenteric vein without invasion and no other detectable secondary lesions in the pancreas or any other abdominal viscera. Patient underwent enucleation of pancreatic tumor. The histological and immunohistochemical findings indicated a functional well-differentiated pancreatic neuroendocrine tumor, G1 category according to the World Health Organization (WHO) criteria, with uncertain behavior (Ki67 index was 3%), confined to the pancreas, but with tumoral invasion of the delimiting conjunctive capsule. No evidence of tumoral CK19 staining, mitoses and necrosis, angioinvasion or extra-pancreatic invasion was observed. A post-operative nine-month follow-up showed resolution of hypoglycemic symptoms, normalized blood glucose and insulin levels and no evidence of recurrence. Our case report highlights the pitfalls in diagnosing a functional pancreatic neuroendocrine tumor due to atypical symptoms, the difficulty of identification and precise location of the small-size tumor and uncertain histopathological and immunohistochemical behavior.

Gastrointestinal stromal tumors - a clinical-morphological study on 15 cases.

AIM: The authors present their experience in addressing the gastrointestinal stromal tumors (GIST). MATERIALS AND METHODS: 15 GISTs operated in the last five years (2008-2013) were analyzed. RESULTS: The preoperative diagnosis was difficult: established by clinical examination and CT in two cases; imagistic accidental discovery in four cases and revealed by evolving complications in nine cases (gastrointestinal bleeding in four cases and bowel obstruction in five cases). CT may be useful in the preliminary estimation of the tumor extent. Tumor location was: stomach four, duodenum one, small bowel seven, and colon three. Pathological examination set the main criteria for assessing the risk of recurrence and indication for adjuvant therapy: the tumor size, the histological type (spindle cell nine, epithelioid four, and mixed two) and the mitosis rate, while the immunohistochemistry examination established the correct diagnosis (positivity for CD117 and CD34) and criteria of aggressiveness (positivity for Ki67). All cases were operated, the surgical procedure being chosen according to the tumor location and stage. Adjuvant therapy with Imatinib 400 mg/day was performed in the 12 cases with high risk of recurrence. The therapeutic outcome was: a postoperative morbidity rate of 13.3%, four patients cured, one local recurrence under Imatinib therapy, a mortality rate of 6.6% and 10 patients in different phases of adjuvant therapy. CONCLUSIONS: GIST has been imposed over the last decade as the main type of non-epithelial tumor of the digestive tract. The preoperative imagistic investigations can be very useful for setting the surgical strategy. The improvement of the mitotic index and/or Ki67 labeling index (LI) determination could render more accurate the scales for prognostic assessment. The two steps algorithm - surgery + adjuvant therapy - still remains the only option to make this dangerous condition a curable one.

Perioperative inflammatory response in natural orifice translumenal endoscopic surgery.

BACKGROUND: Natural orifice translumenal endoscopic surgery (NOTES) could offer multiple advantages compared with the laparoscopic approach. One such potential advantage, not yet proven, is the inferior inflammatory response, which translates into less significant operative stress. This study aimed to compare the immuno-inflammatory response between transgastric NOTES and laparoscopy for simple surgical procedures (oophorectomy) with reference to the cytokine levels. METHODS: For this study, 20 female pigs were randomly assigned to either NOTES or laparoscopic oophorectomy. Seven animals were used as a control group and received only general anesthesia, with no other procedure performed. Blood samples were obtained before surgery, 1 h after the start of the procedure, and at the end of the intervention. The serum levels of IL1ß and IL6 were determined using a porcine enzyme-linked immunosorbent assay (ELISA) kit. The mean operative time, intraoperative incidents, and postoperative complications were recorded. On postoperative day 14, the animals were killed, and gastric leak tests were performed. RESULTS: Both the NOTES and laparoscopic procedures were successfully completed. No gastric leaks were observed during necropsy. The transgastric oophorectomy required a significantly longer time to perform than the laparoscopic surgery. Compared with the NOTES procedures, laparoscopic oophorectomy resulted in significantly higher levels of interleukin-1ß (IL1ß) (42.34 ± 5.26 ng/ml with NOTES vs 46.93 ± 4.79 ng/ml with laparoscopy; p = 0.028) and IL6 (66.95 ± 7.29 ng/ml with NOTES vs 71.75 ± 4.76 ng/ml with laparoscopy, p = 0.049) during the postoperative phase. No statistical difference was detected between the pre- and postoperative cytokine levels in the NOTES group. CONCLUSION: The study findings suggest that pure transgastric endoscopic surgery is a safe approach resulting in less perioperative inflammatory response than laparoscopy in the early postoperative phase.

Retroperitoneoscopic lumbar sympathectomy: prospective study upon a series of 50 consecutive patients.

BACKGROUND: Lumbar sympathectomy (LS) is still indicated for peripheral arterial occlusive diseases (PAOD) with critical ischemia beyond any vascular reconstruction. The retroperitoneoscopic approach was proven feasible and effective but its results were never evaluated in larger series. METHODS: Between January 2007 and January 2009, 50 patients were included in a prospective study (age range = 49-71 years; sex ratio: M/F = 9:1). Their comorbidities included arterial hypertension, n = 12 (24%); atrial fibrillation, n = 4 (8%); cerebral stroke sequels, n = 4 (8%); diabetes mellitus, n = 6 (12%); chronic coronary ischemic disease, n = 20 (40%); and obstructive bronchitis, n = 4 (8%). Fifty-one retroperitoneoscopic lumbar sympathectomies were performed (31 on the left side and 20 on the right side; 1 patient was operated on both sides). RESULTS: Intervention was successful in 50 cases (98.04%), with one conversion in the first three cases. Results were excellent in all patients, with warming of the extremity and regression of pain. The pathology report confirmed excision of the ganglia in all cases. Complications included 3 cases (6%) of accidental peritoneal tear and pneumoperitoneum which were resolved by insertion of a Veress needle in the hypochondrium; 2 (4%) retroperitoneal hematoma, and 6 (12%) superficial wound infections. Operative time was 65-105 min in the first ten cases and <40 min for the last 41. There was no neuralgia, sexual dysfunction, or postoperative mortality. Associated interventions included necrectomy in 10 cases. The limb preservation rate was 77.09% at 1 year and 58.69% at 2 years. CONCLUSION: For a larger number of cases, retroperitoneal LS has been proven effective and safe in PAOD beyond reconstruction.

Immunohistochemical assessment of angiogenesis in primary hepatocellular carcinoma.

BACKGROUND: Primary hepatocellular carcinoma (HCC) is characterized by the presence of angiogenesis, which is necessary for tumor growth, progression and distant metastasis. Vascular endothelial growth factor (VEGF) is clearly expressed in HCC, in variable degrees as a function of differentiation and vascularisation. AIM: To assess angiogenesis in HCC, by means of immunohistochemical analysis of the expressions of VEGF. METHOD: Immunohistochemical techniques were performed on the samples obtained by ultrasound-guided liver biopsies or intraoperative biopsies, in 32 patients with HCC. RESULTS: Positive expression of VEGF was always observed in the extracellular matrix of portal tracts of the non-neoplastic or tumor areas (extra- and intranodular areas of HCC patients). VEGF was not expressed inside the hepatocytes of extranodular non-neoplastic areas of the patients with HCC. However, we did find positive reactions for VEGF inside the tumor hepatocytes in 34.38 % of the HCC patients. The difference between VEGF expression for the patients with poor and undifferentiated HCC as compared with moderate and well-differentiated HCC was statistically significant (P < 0.05). CONCLUSION: Our study demonstrated an increased VEGF expression in tumor hepatocytes, which progressed with the dedifferentiation of HCC. VEGF expression was always present in the extracellular matrix, supporting the hypothesis of paracrine activation of VEGF at the level of tumor stroma. Consequently, increased VEGF expression might be responsible for the activation of angiogenesis in HCC.

Preoperative "two-way" enteroscopy, followed by intraoperative enteroscopy in a patient with obscure-overt gastrointestinal bleeding and severe iron-deficiency anemia.

We present the case of a 69-year-old woman admitted to hospital because of chronic gastrointestinal bleeding of an unknown source with a consequent severe iron deficiency anemia (IDA), undiagnosed for the past 25 years. In the last three years the episodes of severe bleeding became frequent, usually followed by melena. The patient was admitted 11 times in different departments without the identification of the bleeding source. During the evolution of the disease, the biological exams showed a severe IDA with low values of hemoglobin, low serum iron, mixed deficiency depicted by bone-marrow examination, and a reticulocyte crisis after parenterally administered iron. Repeated upper (6) and lower (2) gastrointestinal endoscopies failed to find a source of bleeding. Push enteroscopy allowed the visualization of approximately 40 cm of the proximal jejunum, after the Treitz angle, and demonstrated multiple punctiform jejunal angiodysplasias, which bled excessively after bipolar coagulation. We also performed a total colonoscopy with intubation of the ileo-cecal valve and visualization of the terminal ileum on approximately 30 cm, without any pathological findings. Because endoscopic treatment was ineffective, we decided to perform a segmentary enterectomy, with the length of small bowel resection tailored by intraoperative enteroscopy. A favourable evolution after limited resection of the small bowel indicated the importance of both preoperative "two-way" enteroscopy associated with intraoperative enteroscopy for diagnosing and treating the source of obscure gastrointestinal bleeding
