Radical resection is the only curative treatment for pancreatic cancer. However, only up to 20% of patients are considered eligible for surgical resection at the time of diagnosis. Although upfront surgery followed by adjuvant chemotherapy has become the gold standard of treatment for resectable pancreatic cancer there are numerous ongoing trials aiming to compare the clinical outcomes of various surgical strategies (e.g., upfront surgery or neoadjuvant treatment with subsequent resection). Neoadjuvant treatment followed by surgery is considered the best approach in borderline resectable pancreatic tumors. Individuals with locally advanced disease are now candidates for palliative chemo- or chemoradiotherapy; however, some patients may become eligible for resection during the course of such treatment. When metastases are found, the cancer is qualified as unresectable. It is possible to perform radical pancreatic resection with metastasectomy in selected cases of oligometastatic disease. The role of multi-visceral resection, which involves reconstruction of major mesenteric veins, is well known. Nonetheless, there are some controversies in terms of arterial resection and reconstruction. Researchers are also trying to introduce personalized treatments. The careful, preliminary selection of patients eligible for surgery and other therapies should be based on tumor biology, among other factors. Such selection may play a key role in improving survival rates in patients with pancreatic cancer.

Small bowel tumours are rare and comprise less than 2 % of all primary gastrointestinal neoplasms. Among these tumours, a leiomyosarcoma belonging to soft tissue sarcomas is extremely rare and accounts for about 1 % of malignant mesenchymal lesions in the gastrointestinal tract. Due to its aggressive nature and slow growth, it is often diagnosed at the late stage when curative treatment is impossible. Authors report a first case of leiomyosarcoma with chronic recurrent ileocaecal intussusception and literature review to analyse diagnosis and treatment features of the ileum mesenchymal tumours. We present a case of an 87-year-old Caucasian man suffering from cramp-like abdominal pain for months. Due to lack of clinical signs and unspecific complaints, a diagnosis was delayed. Despite a detailed in-hospital examination, a proper diagnosis was established as late as during an operation. The patient was treated by surgery with good results. An uncommon laparoscopic resection of the small bowel with a tumour was performed. A histopathological investigation confirmed a very rare mesenchymal lesion of the distal ileum. The patient is under control with no recurrence for 1 year of the follow-up period. Reported case indicates that a usually asymptomatic tumour can cause uncommon chronic recurrent ileus signs. CT and MRI scans are investigation of choice in such cases, but they are sometimes inconclusive. It might be worth highlighting the good results of laparoscopic leiomyosarcoma lesion resection with a very good outcome.

Objectives: Resveratrol (RES) is well documented for its multiple health benefits, with a notable impact on cancer prevention and therapy. This study aimed to evaluate the effect of RES supplementation on oxidative stress in patients with head and neck cancer (HNC) receiving home enteral nutrition (HEN). Methods: This randomized, single-center, open-label study involved 72 adult patients, with 40 completing the intervention. Participants in the intervention group received 400 mg of liposomal RES daily for 12 weeks alongside HEN, while the control group received HEN only. Body composition and oxidative stress markers—including total antioxidant capacity (TAC), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), and reduced glutathione (GSH)—were measured at baseline and after 12 weeks. Results: Significant increases in TAC and SOD activity were observed in both groups. GPx activity increased significantly only in the RES group. MDA levels rose in both groups but were more pronounced in the RES group. GSH levels showed no significant changes. Phase angle (PhA) increased significantly in the RES group, while no significant change was observed in the control group. Conclusions: RES supplementation may enhance antioxidant defenses, as evidenced by increased GPx activity and improvements in TAC and SOD levels, supporting oxidative balance in patients with HNC receiving HEN. The higher MDA levels in the RES group may reflect RES’s dual antioxidant and pro-oxidant activities. Additionally, the observed increase in PhA suggests potential cellular health benefits. These findings highlight the potential of RES as a complementary antioxidant intervention in clinical oncology, warranting further investigation to clarify its therapeutic effects on oxidative stress and cellular health in cancer care.

Recent studies have obtained inadequate data on the association between nutritional status, body composition, clinical parameters and tumor stage in patients withpancreatic and periampullary tumors. The purpose of this study was to assess the relationship between nutritional status (NS), body composition (BC) and selected clinical parameters in patients with pancreatic and periampullary cancer, as well as describe the differences between resection and non-resection groups. This is a prospective study of 76 patients with pancreatic and periampullary tumors. We evaluated NS, BMI, body mass loss (BML) and albumin, total protein, CRP, CEA, CA19-9, lipase, amylase, tumor stage, and BC using bioelectrical impedance (BIA). All subjects were divided into resection (n = 59) and non-resection (n = 17) groups. The non-resection group had a worse NS, as well as increased amylase and WBC, compared to the resection. The selected parameters of BC corresponded to BML albumin, TP, NS, age, BMI, Karnofsky, RBC, HCT and HGB. No associations were found between BC with tumor size, CRP, CA19-9, and CEA. We recorded the relationship between metastasis and NRS, as well as tumor size with SGA. The percentage of BML was positively correlated with age and CRP but negatively correlated with RBC, HGB, HCT and anthropometric measurements. We found many statistical correlations with NS and selected parameters, as well as differences between the resection and non-resection group. The detection of early prognostic factors of nutritional impairments would improve the quality of life and reduce the rate of postoperative complications.

Postinflammatory pancreatic pseudocysts are one of the most common complications of acute pancreatitis. In most cases, pseudocysts self-absorb in the course of treatment of pancreatitis. In some patients, pancreatic pseudocysts are symptomatic and cause pain, problems with gastrointestinal transit, and other complications. In such cases, drainage or resection should be performed. Among the invasive methods, mini invasive procedures like endoscopic transmural drainage through the wall of the stomach or duodenum play an important role. For endoscopic transmural drainage, it is necessary that the cyst wall adheres to the stomach or duodenum, making a visible impression. We present a very rare case of infeasibility of endoscopic drainage of a postinflammatory pancreatic pseudocyst, impressing the stomach, due to cyst wall calcifications. A 55-year-old man after acute pancreatitis presented with a 1-year history of epigastric pain and was admitted due to a postinflammatory pseudocyst in the body and tail of pancreas. On admission, blood tests, including CA 19-9 and CEA, were normal. An ultrasound examination revealed a 100-mm pseudocyst in the tail of pancreas, which was confirmed on CT and EUS. Acoustic shadowing caused by cyst wall calcifications made the cyst unavailable to ultrasound assessment and percutaneous drainage. Gastroscopy revealed an impression on the stomach wall from the outside. The patient was scheduled for endoscopic transmural drainage. After insufflation of the stomach, a large mass protruding from the wall was observed. The stomach mucosa was punctured with a cystotome needle knife, and the pancreatic cyst wall was reached. Due to cyst wall calcifications, endoscopic drainage of the cyst was unfeasible. Profuse submucosal bleeding at the puncture site was stopped by placing clips. The patient was scheduled for open surgery, and distal pancreatectomy with splenectomy was performed. The histopathological examination confirmed the initial diagnosis of postinflammatory pancreatic pseudocyst. Endoscopic transmural drainage is a highly effective procedure for treating postinflammatory pancreatic pseudocysts. In some patents, especially with large pseudocysts, pseudocysts with calcified walls, and cysts of primary origin, resection should be performed.

Background: This study aimed to objectively evaluate the impact of the gap in surgical practice caused by COVID-19 on surgical skill decay. Methods: This retrospective cohort study enrolled 148 cases of adult patients who were qualified for elective or urgent laparoscopic cholecystectomy. This study compared the period of nine months before the pandemic outbreak and nine months after the end of the pandemic. We analyzed the duration of surgery, the number of intraoperative adverse events (IAEs), postoperative complications (PCs), and differences between the surgeries performed by residents and those performed by specialists. Results: The number of IAEs did not differ significantly between groups (after COVID-19 (AC) and before COVID-19 (BC)). A difficult gallbladder (DGB) was associated with an increased risk of IAEs during surgery in both groups (BC:OR = 2.94, p = 0.049; AC:OR = 2.81, p = 0.35). The multivariate analyses showed no significant differences in IAEs or PCs when the residents performed surgeries compared to specialists. The average duration of surgery was significantly longer in the post-pandemic group (BC–102.4 min vs. AC–119.9 min, p = 0.024). Conclusions: Measurable determinants of surgical skills are the duration of surgery and the number of intraoperative adverse events. By defining this indicators, our study objectively shows that the reduction in the volume of surgeries during COVID-19 resulted in a phenomenon known as surgical skill decay.
