Appendiceal mucocele is a rare entity first described by Carl von Rokitansky, characterized by cystic dilatation of the appendiceal lumen due to obstruction, epithelial proliferation or inflammation and accumulation of mucoid material. The cause can be either neoplastic or non-neoplastic. Patients with appendiceal mucocele can be asymptomatic or present with right lower quadrant pain which may mimic acute appendicitis.

Article Synopsis
  • - Colorectal cancer (CRC) poses a significant health challenge globally, particularly affecting survival rates in patients with metastatic CRC, prompting a study of various clinical and laboratory parameters among 188 patients with liver metastases from 2016 to 2023.
  • - Key findings suggest that higher Body Mass Index (BMI) and lymphocyte counts correlate with improved survival, whereas elevated scores on the Neutrophil-Hemoglobin-Lymphocyte (NHL) index, Neutrophil-Lymphocyte Ratio (NLR), Platelet-Lymphocyte Ratio (PLR), and Systemic Immune-Inflammation Index (SII) indicate poorer outcomes; notably, liver metastasis at diagnosis significantly decreases overall survival.

Background: Pregnancy-related infections with the human herpes simplex virus (HSV) strains HSV-1 and HSV-2 are particularly noteworthy. There are numerous reported examples of intrapartum transmission of herpes infection, notwithstanding the extreme rarity of intrauterine transfer from mother to fetus. The purpose of this study was to evaluate the seroprevalence of HSV-1 and HSV-2 antibodies in pregnant women in the western region of Romania.

Groove pancreatitis represents a chronic focal form of pancreatitis affecting the zone between the pancreatic head and the duodenal "C" loop, known as the groove area. This is a rare condition that affects the pancreatic periampullary part, including the duodenum and the common bile duct, which is usually associated with long-term alcohol and tobacco misuse, and is more frequent in men than in women. The most common clinical symptoms of groove pancreatitis include weight loss, acute abdominal pain, nausea, and jaundice.

Chondrosarcoma (CHS) is a malignant tumor of soft tissue with cartilaginous differentiation that represent one tenth of all malignant proliferations developed from bone tissues. Even if CHS represents the third malignancy with bone localization, after myeloma and osteosarcoma, it is far less diagnosed in the head and neck region. The current paper presented two cases of conventional CHSs, which were diagnosed in Department of Thoracic Surgery and Department of Otorhinolaryngology of Emergency City Hospital, Timişoara, Romania, between February and June 2021.

Colorectal cancer remains an important cause of morbidity and mortality worldwide. We present the case of a 58-year-old male patient admitted in Timişoara Hepato-Biliary-Pancreatic Surgical Center, Romania, with transverse colon cancer and synchronous liver metastases, who underwent a major hepatectomy and a segmental colon resection performed in the same operative time. The patient had a postoperative outcome without major complications and with no signs of local or distant recurrence at 15 months postoperatively.

Hemobilia is a rare cause of upper digestive bleeding, and it should be suspected when there are traumas of the liver area or surgical or exploratory interventions of the liver-bile-pancreas area in the patient's history. Iatrogenic bleeding occurs, most often, after transcutaneous bile punctures, laparoscopic cholecystectomies, cateterisms of the biliary ways. After such interventions, hemobilia may appear earlier, but also up to a few months later.

Background: The multiple-traumatic critical patient presents a variety of pathophysiological, cellular, and molecular dysfunctions. One of the most important is represented by mitochondrial damage which afterwards is responsible for the augmentation and worsening of a series of pathologies that lead to the worsening of the clinical status of the patient. The severe inflammatory response, sepsis, and the redox imbalance are other pathologies that together with the multiple traumas are responsible for the mitochondrial dysfunctions.

Background: One of the major causes of mortality in the world is represented by multiple traumas. Thoracic trauma is commonly associated with polytraumas. A series of physiopathological complications follow polytraumas, leading to a significant decrease in the survival rate.

Introduction: Cephalic pancreaticoduodenectomy (CPD) is the only current treatment method that can provide long-term survival in patients with periampullary tumors.

Case Presentation: This study is a prospective study conducted between 2010 and 2016 in Hepato-Biliary-Pancreatic Center of "Victor Babes" University of Medicine and Pharmacy, Timisoara, Romania, where 57 modified Whipple-Child CPDs with anastomoses on jejunal loop in continuity were performed, in patients with periampullary tumors. Twelve patients, who had undergone prior biliodigestive derivations or biliary drainage using endoscopic retrograde cholangio-pancreatography (ERCP), with stenting of the common bile duct, were excluded from the study.
