Objective: The aim of this study is to verify if the experience on 4 years in using minimally invasive techniques in the treatment of CE could match regarding the indications and results with the major studies on topic. Method: During 03.2014 - 03. 2018 period, 38 PAIR, 28 MoCaT procedures and 7 percutaneous drainages have been performed at 51 patients from 76 cases of hydatid hepatic cysts (67,1%). There were 26 men and 25 women, and the age ranged from 19 to 78. 7 patients have had 2 hydatid hepatic cysts or more and 2 procedures were performed at 3 of those patients; other 11 patients needed the second procedure during the surveillance. Results: The evolution of the patients was favorable, and the surveillance was 2 years post-intervention at least. There were no major surgical adverse effects. We defined as an expected result obtaining a scar lesion or a small cavity with calcified walls (hyperechoic). Only 2 (3,9%) patients needed conversion to open surgery. The complications we have faced were represented by the cystic-biliary fistula in 15 cases (29,4%) and the re-opening of the cyst's cavity in 11 cases (21,67%). Conclusions The percutaneous treatment of CE is safe and effective, following the correct assignation according with the cysts' type. The percutaneous treatment of CE is an easier alternative to the open surgery and has lower rate of complications and relapses, and a shorter hospitalisation. Now routine, it becomes slighty the first option for invasive treatment of CE. The role of open surgery is restricted to CE with severe complications.

Despite the substantial decrease in mortality rates following a pancreaticoduodenectomy to less than 5%, morbidity rates remain significant, reaching even 73%. Postoperative pancreatic fistula is one of the most frequent major complications and is significantly associated with other complications, including patient death. Currently, there is no consensus regarding the ideal type of pancreatic anastomosis, as the question of the choice between a pancreaticogastrostomy and pancreaticojejunostomy is still open. Furthermore, worldwide implementation of an ideal pancreatic fistula risk prediction score is missing. Our study found several significant predictive factors for the postoperative occurrence of fistulas, such as the soft consistency of the pancreas, non-dilated Wirsung duct, important intraoperative blood loss, other perioperative complications, preoperative patient hypoalbuminemia, and patient weight loss. Our study also revealed that for patients who exhibit fistula risk factors, pancreaticogastrostomy demonstrates a significantly lower pancreatic fistula rate than pancreaticojejunostomy. The occurrence of pancreatic fistulas has been significantly associated with the development of other postoperative major complications, and patient death. As the current pancreatic fistula risk scores proposed by various authors have not been consensually validated, we propose a simple, easy-to-use, and sensitive score for the risk prediction of postoperative pancreatic fistula occurrence based on important predictors from statistical analyses that have also been found to be significant by most of the reported studies. The new pancreatic fistula risk score proposed by us could be extremely useful for improved therapeutic management of cephalic pancreaticoduodenectomy patients.

Colorectal cancer (CRC) remains a major global health burden, necessitating continuous advancements in diagnostic methodologies. Traditional screening techniques, including barium enema and fecal occult blood tests, have been progressively replaced by more precise modalities, such as colonoscopy, liquid biopsy, and artificial intelligence (AI)-assisted imaging. Objective: This review explores the evolution of CRC diagnostic tools, from conventional imaging methods to cutting-edge AI-driven approaches, emphasizing their clinical utility, cost-effectiveness, and integration into multidisciplinary healthcare settings. Methods: A comprehensive literature search was conducted using the PubMed, Medline, and Scopus databases, selecting studies that evaluate various CRC diagnostic tools, including endoscopic advancements, liquid biopsy applications, and AI-assisted imaging techniques. Key inclusion criteria include studies on diagnostic accuracy, sensitivity, specificity, clinical outcomes, and economic feasibility. Results: AI-assisted colonoscopy has demonstrated superior adenoma detection rates (ADR), reduced interobserver variability, and enhanced real-time lesion classification, offering a cost-effective alternative to liquid biopsy, particularly in high-volume healthcare institutions. While liquid biopsy provides a non-invasive means of molecular profiling, it remains cost-intensive and requires frequent testing, making it more suitable for post-treatment surveillance and high-risk patient monitoring. Conclusions: The future of CRC diagnostics lies in a hybrid model, leveraging AI-assisted endoscopic precision with molecular insights from liquid biopsy. This integration is expected to revolutionize early detection, risk stratification, and personalized treatment approaches, ultimately improving patient outcomes and healthcare efficiency.

Background: Breast cancer still represents the most commonly diagnosed cancer among women, accounting for 12.5% of all new annual cancer cases worldwide. In Romania in 2020, breast cancer was the most common, with a share of new cases of 26.9%, far behind the rates of colon cancer (11.8%) and cervix cancer (7.5%). The aim of this study is to reveal five years of experience in treating breast cancer at the Surgical Clinic of the Colentina Hospital in Bucharest, Romania. Methods: Retrospective analysis, including 68 patients admitted to our clinic between January 2019 and December 2023 undergoing modified radical mastectomy, sectorectomy, or subcutaneous mastectomy. Results: Madden-modified radical mastectomy with total excision of the axillary lymph nodes accounted for 77.94% of surgeries, with a complication rate of 13.2%, represented by lymphedema of the ipsilateral arm and prepectoral seroma. Conclusions: Continuous innovation regarding early diagnosis and treatment methods in our surgical clinic will, hopefully, contribute to improving the outcomes of our patients.

The gallbladder pathology is mainly represented by cholelithiasis, treated with cholecystectomy, one of the most commonly performed surgical procedures, continues to raise some challenges. Despite the advancements in surgical techniques, especially in those patients presenting some particularities, such as cirrhotic patients or those with sclero-atrophic or acute gangrenous cholecystitis, difficulties continue to arise. This review, including an evaluation of the literature from the last 20 years, aims to explore the pathophysiological mechanisms and surgical approaches for these high-risk conditions. Emphasis is placed on tailoring management strategies in order to reduce complications and improve outcomes, offering insights for optimizing care in difficult cholecystectomies.

Microthrombi formation in the pulmonary circulation is one of the main pathophysiological mechanisms responsible for the unfavorable respiratory evolution of CoViD-19 patients. Low molecular weight heparin (LMWH) anticoagulant therapy is a major pillar of treatment. But sometimes LMWH causes severe complications that can result in death. This is a retrospective, descriptive study, covering September 2020 and presenting 3 cases of severe hemorrhages followed by death in COVID-19 anticoagulated patients in therapeutic doses with LMWH in the hospital units of origin. Patients had hematomas of the rectus abdominal muscles and hemoperitoneum (2 cases) respectively hematoma of left gluteal muscles (1 case). The 2 patients with hematoma of rectus abdominal muscles were operated. The death occurred between 1-4 days after hospitalization.
