Background and Objectives: Sarcopenia is a recognized prognostic factor for both complications and survival in cancer patients. This study aims to analyze the relationship between sarcopenia measured by psoas muscle index on computer tomography scans and the presence of postoperative complications in colorectal cancer surgery. Materials and Methods: In a prospective study we recorded data from 51 patients who underwent colorectal cancer surgery in the Mures County Clinical Hospital, Romania. Total psoas muscle area and psoas density were measured at the level of the third lumbal vertebra (L3) for further index calculation. We also evaluated the general characteristics and laboratory analyses to obtain more information about status of the patients. Short-term postoperative complications were scored according to the Clavien-Dindo classification. Results: The majority of the 51 patients were male (61%) and the median age was 65 years. More than half of the cancer was located in the rectum (56.9%), a quarter in the right colon (25.5%), the rest in the sigmoid (11.8%), and the left colon (5.9%). Twenty-one patients (41.2%) developed a complication, five (9.8%) of these were Clavien-Dindo grade 3, 4 or 5 (high grade) and sixteen (31.3%) grade 1 or 2 (low grade). The low- and high-grade groups showed a significantly lower right psoas muscle area, left psoas muscle area, total psoas muscle area, and psoas muscle index (p < 0.001 in all cases). Among laboratory analyses, a significantly lower perioperative hematocrit, hemoglobin, and albumin level were found in patients who developed complications. Furthermore we observed that an elevated serum C-reactive protein level was associated with a higher grade of complication (p < 0.043). Conclusions: The psoas muscle index (PMI) influence on the postoperative outcome is an important factor in our single center prospective study and it appears to be a good overall predictor in colorectal surgery. A lower PMI is directly associated with a low or high grade complication by Clavien-Dindo classification. Perioperative inflammatory and nutritional status evidenced by serum C-reactive protein (CRP) and albumin level influences the presence of postoperative complications.

Introduction: Lymph node metastasis is regarded as an important prognostic factor for predicting disease recurrence and survival in patients with colorectal cancer. Several studies suggest that the lymph node ratio has a greater importance in survival than the number of metastatic lymph nodes. The scope of this study is to examine the 5-year survival of rectal cancer patients, examining several prognostic factors with emphasis on lymph node status. Material and Methods: A retrospective study was conducted at single surgical clinic from Romania, using data from patients who have been treated for rectal cancer between January 2009 and December 2014. Patient present status and regarding the multimodal treatment was assessed through telephonic method, data was extracted from the electronic database of the clinic and histopathological reports. Results: A total number of 144 patients affected by rectal cancer were assessed. Statistical analysis of the variables showed that age (p=0.001), T stage(p=0.049), N stage (p=0.005), LNR (p=0.006), type of surgery (p 0.001), presence of vascular invasion (p 0.001), metastases (p 0.001), to be significant prognostic factors for survival. Conclusions: The 5-year survival of the patients we included in the study was 63,9%. Nodal status, expressed by lymph node ratio proved to be a significant prognostic factor of patient survival.

Introduction: The creation of an abdominal stoma is a common procedure performed by surgeons as a part of the treatment for benign and malignant conditions in general surgery. Stoma formation is simple, but sometimes the associated postoperative complications have an impact on the patients’ physical and psychological state. The majority of complications do not require reoperation, but when it is indicated, we have to assess the most appropriate option for the patient. Material and Methods: We conducted a retrospective study in a single surgical center, the Department of Surgery, Mureș County Hospital, Târgu Mureș, Romania, using data from patients who have been admitted under elective conditions for stoma-related complications between 2005 and 2019. Results: A total number of 877 ostomies (653 colostomies and 224 ileostomies) were performed, and 157 patients (17.9%) developed some type of stoma complication and required surgical intervention. The mean age was 64.5 ± 2.1 years, with a male-female ratio of 1.3 to 1. The leading comorbidities included cardiovascular disease (52.2% of cases), obesity (22.2%), and diabetes (18.4%). Parastomal hernia was the most frequent complication (47.5% of cases), followed by stoma prolapse (23.4%), parastomal stenosis (20.3%), and parastomal infection (8.2%). There was an association between age and the type of complication: parastomal hernia, stoma prolapse, and stenosis were more frequent in the elderly; parastomal infection was more prevalent in young patients. A longer hospital stay was observed in case of parastomal hernia. Conclusions: Stoma formation is associated with significant morbidity. Typically, the complications appear in the elderly. Conservative treatment is essential, but some of the late complications, such as parastomal hernia, stoma stenosis, stoma prolapse, and parastomal infection, require a surgical solution. Parastomal hernias are the most common complications, frequently associated with comorbidities and prolonged hospitalization.

Background: Clostridium difficile (CD) is the major cause of nosocomial antibiotic-associated infections, having as main manifestation diarrhea and life-threatening inflammation of the colon. Surgery may be necessary in up to 80% of patients due to the frequent complications associated with this condition. The mortality rate of this devastating disease could reach 50% even after proper treatment. Case report: We report a case of a 24-year-old female who was admitted with clinical signs of an odontal inflammatory process. After repeated surgical treatments and antibiotic therapy, she presented acute abdominal pain on the 14th postoperative day. The explorative laparotomy was negative. Clostridium difficile was isolated from her stool, and she was transferred to the Department of Infectious Diseases. After a few days without any favorable clinical outcome, she was transferred to the intensive care unit (ICU), where she developed acute respiratory distress syndrome. Despite the immediate surgical intervention and ICU care, she died within 15 days after admission. Conclusions: CD infection is considered a complication of antibiotic treatment, having as main cause the combination of fluoroquinolones with antisecretory drugs. In the first phase, the changes of the colon can be minimal with the manifestation of a false acute surgical abdomen, but toxic colon can develop in evolution, leading to multi-system organ failure and death.

Malignant melanoma is a neoplasia that has its origin in the melanocytes, the melanin-synthesizing pigment cells present in the epidermis or sometimes in the dermis. Sentinel lymph node biopsy (SLNB) is the standard procedure used for staging patients with malignant melanoma in the majority of surgical centers in the world. With a probability of approximately 20% of finding positive lymph nodes, it spares a large number of patients of a complete lymphatic dissection. The aim of this study is to evaluate the factors that can predict the positivity of sentinel lymph nodes in malignant melanoma patients. We performed a retrospective study analyzing the histopathologic reports of patients who underwent SLNB for malignant melanoma between 2012 and 2015. There were 32 patients identified, out of which only three (9.37%) had positive SLN, so the majority of our patients were spared of regional lymphatic dissection. In our series, lymphatic invasion (p = 0.01), Breslow index >4 mm (p = 0.0064), AJCC staging (p = 0.0008), the presence of precursory lesions (p = 002), and microsatellitosis (p = 0.017) were predictive factors for the positivity of the SLN in malignant melanoma patients. Although our results are similar to those published in the literature, we consider that larger cohort studies should be performed to consolidate our results.

Intoduction and aim: The aim of the study was to compare the resistance to pressure of stapled and manually handsewn intestinal suture lines on in vitro pig intestine model. Method: We performed different types of stapled and manual sutures and the pressure level was measured using a differential pressure manometer. Results: Although the hand-sewn end-to-end suture turned out to be the most resistant to pressure, statistical analysis revealed no significant differences compared to stapled suture (p = 0.49). In stump closure techniques, we observed a statistically high significance in resistance to pressure in the favour of manual stump closure (p = 0.004).Regarding side-to-side sutures we did not find any statistically significant differences in resistance to pressure between the techniques (p = 0.06). Conclusion: We can conclude that regarding the stump closure, the most resistant to pressure is the hand-sewn procedure, but in the other types of anastomosis, no significant differences was found between the stapled and hand-sewn techniques.
