ABSTRACT
Background: Gastric gastrointestinal stromal tumors (GISTs) represent a subset of gastrointestinal tumors predominantly found in the stomach. Despite their rarity, these tumors carry significant implications for patient health and management. GISTs are potentially malignant tumors with unpredictable progression. They originate from the interstitial cells of Cajal, which are positioned between the intramural neurons and the smooth muscle cells of the digestive tract. These tumors are characterized primarily by mutations in the c-Kit gene, as well as other mutations such as those in the platelet-derived growth factor receptor alpha (PDGFRA) gene. Methods: Our comprehensive search across five databases initially yielded 2976 articles. After eliminating 197 duplicates, we screened the titles and abstracts of 2779 articles, excluding 2692 for not meeting the inclusion criteria. During the full-text screening, 16 more articles were excluded. Ultimately, 71 papers met the inclusion criteria and were included in our analysis. Results: Due to differences in study designs, inclusion criteria for patients, and reported outcomes, a meta-analysis was not conducted. The accurate diagnosis of GIST is established through histopathological examination and immunohistochemistry. Histopathologically, GISTs are classified into three main types: spindle cell, epithelioid, and mixed. The therapeutic management of GIST involves surgery, endoscopic treatment, and chemotherapy. Conclusions: The prognosis for GIST patients depends on various factors, including risk category, disease stage, applied treatments, and recurrence post-treatment. A significant recent advancement comes from artificial intelligence, which can be increasingly involved in both the diagnosis and treatment of this tumor.
ABSTRACT
INTRODUCTION: This prospective study aims to illustrate the histopathological arterial changes in the popliteal artery in peripheral arterial disease of the lower limbs. MATERIAL AND METHOD: A total of 60 popliteal artery segments taken from patients who had undergone lower limb amputation were examined between April and June 2023. The degree of arterial stenosis, medial calcinosis, and the vasa vasorum changes in the arterial adventitia were quantified. The presence of risk factors for atherosclerosis was also observed. RESULTS: Atherosclerotic plaque was found in all of the examined segments. Medial calcinosis was observed in 40 (66.6%) of the arterial segments. A positive association between the degree of arterial stenosis and the vasa vasorum changes in the arterial adventitia was also found (p = 0.025). The level of blood sugar and cholesterol were predictive factors for the severity of atherosclerosis. CONCLUSIONS: Atherosclerosis and medial calcinosis are significant in patients who underwent lower limb amputation. Medial calcinosis causes damage to the arterial wall and leads to a reduction in responsiveness to dilator stimuli.
ABSTRACT
Background: Chronic postoperative inguinal pain (CPIP) is still the most frequent complication after open Lichtenstein repair and any strategy to reduce its incidence and implications is a step forward to better outcomes. Between the means of mesh fixation atraumatic glue fixation has been explored as such possibility. A meta-analysis of randomized controlled trials comparing the performance of cyanoacrylate glue versus sutures fixation was conducted. Methods: the meta-analysis was conducted according to the PRISMA guidelines. Randomized controlled trials (RCTs) published between January 2000 and December 2021 were searched for in MEDLINE, PubMed, Web of Science, and Google Scholars. The quality of RCTs and the potential risk of bias were assessed using MINORS criteria and the Cochrane risk of bias tool. Results: of 269 papers the meta-analysis was performed on 19 RCTs including 3578 patients. In the glue fixation group, the operation was shorter (mean pooled difference 6 minutes; SE = 0.47; 95% CI = - 6.77 - - 4.92; t test = -12.36; p 0.0001) and immediate postoperative pain was lower (2.37% vs 13.3%OR - 0.158; 95% CI = 0.064 0.386; p = 0.0001). There was no difference in terms of chronic pain, recurrence rate and wound events. Conclusion: glue fixation of mesh in elective Lichtenstein repair of inguinal hernia seems to be a valid choice for a painful and safe procedure without increasing risk of recurrence.

BACKGROUND: Complex incisional hernia is still a debatable topic, with increasing incidence and an increased local and systemic postoperative morbidity and mortality. The size of the defect is a risk factor for both difficult closure and 30-day readmission due to complications. The main option for closure such defect is a mesh augmented component separation technique. The goal was to evaluate 30-day wound events and general complications including 90 days mortality. MATERIAL AND METHODS: We present a retrospective study that includes patients from two different university hospitals who underwent open incisional hernia repair with anterior component or posterior component separation between January 2015 and December 2021. Only non-contaminated adult patients (over 18 years old) with postoperative primary or recurrent median abdominal wall defects larger than 6 cm and with complete fascial closure were included. Demographics (age, gender, Body Mass Index-BMI, American Society of Anesthesiologists Classification-ASA score), recurrence rank, and co-morbidities), operative details, patient outcomes complications were collected. A native abdomen/pelvis computerized tomography (CT) scan was performed preoperatively in all patients and the anatomy of the defect and volumetry (abdominal cavity volume, incisional hernia volume and peritoneal volume) were evaluated. One of the component separation technique was performed according to Carbonell's equation. RESULTS: Two hundred and two patients (101 from each group) were included. The patients with posterior component separation were more comorbid and with larger defects. The procedure was longer with 80 min but overall length of hospital stay shorter (p < 0.001) for posterior component separation. Seroma, hematoma and skin necrosis were equally distributed for both group of patients and there was no direct relation to surgery (OR 0.887, 95% CI 0.370-2.125, p = 0.788; OR 1.50, 95% CI 0.677-3.33, p = 0.318 and OR 0.386, 95% CI 0.117-1.276, p = 0.119). Surgical Site Infection rate was increased for anterior component separation (p =0.004). CONCLUSION: Complex incisional hernia repair is a challenge given by a large amount of wound complications. Choosing between anterior and posterior component separation is still a source of significant debate. We were not able to depict significant different rates of complications between the procedures and we couldn't find any specific factor related to complications.
ABSTRACT
Diabetes mellitus (DM) and obesity are known to influence postoperative outcomes in surgical patients. This study aimed to analyze the divergence in outcomes between patients with and without DM who underwent ventral hernia repair, while also assessing the additional impact of obesity on postoperative complications, hospitalization, and costs. A prospective, non-interventional, observational study was conducted over five years (2018-2022) at the First Surgical Clinic of Craiova Emergency Clinical Hospital. The study included 216 patients, with 42 (19.44%) having DM, half of whom were also obese. There were no significant differences in age between patients with or without DM. However, diabetes and obesity were more prevalent in female patients. The mean duration of hospitalization was 10.7±8.6 days, with no significant differences observed between patients with or without DM or obesity. Statistical analysis revealed that patients with DM had a higher incidence of seroma formation, wound infection, and hematoma formation compared to patients without DM. However, there were no significant differences in mesh infection, hospitalization days, or costs between the two groups. Similarly, no significant differences were found between obese and non-obese patients in terms of complications, hospitalization days, or costs. In conclusion, this study highlights that DM is associated with an increased risk of specific complications in ventral hernia repair, including seroma formation, wound infection, and hematoma formation. However, the impact of obesity on these outcomes appears to be limited. Individualized preoperative optimization and targeted interventions are necessary to mitigate the risk of complications in patients with DM or obesity.
ABSTRACT
Chronic inflammation is demonstrated to play a direct role in carcinogenesis. Our exploratory study aimed to assess the potential added value of two inflammation biomarkers, chitotriosidase and neopterin, in follow-up evaluation of patients with colorectal cancer (CRC). An observational exploratory study was conducted. Patients with CRC and matched controls (1:1, age, sex, and living environment) were evaluated. The patients with CRC (CRC group) and controls were assessed at baseline (before surgical intervention for patients with CRC). Patients with CRC were also evaluated at 1-year follow-up. Significantly more patients with blood group A (54.5% vs. 25.0%) and smokers (50.0% vs. 22.7%) were in the CRC group. The serum values of chitotriosidase and neopterin were higher in CRC patients than in controls, but only neopterin reached the conventional level of statistical significance (p-value = 0.015). The circulating chitotriosidase and neopterin values decreased significantly at 1-year follow-up (p-value < 0.0001). Patients with higher N- and M-stage showed statistically significant higher levels of chitotriosidase and neopterin at baseline and 1-year follow-up (p-values < 0.03). Circulating chitotriosidase levels also showed statistically significant differences regarding baseline and 1-year follow-up on patients with CRC and different differentiation grades (p-values < 0.02). The circulating levels of neopterin significantly decreased at 1-year follow-up, indicating its potential as a prognostic marker. The circulating values of chitotriosidase and neopterin exhibit significant differences in patients with than without recurrences. Our results support further evaluation of chitotriosidase and neopterin as prognostic markers in patients with CRC.
ABSTRACT
Abdominal cystic masses are diagnosed during the intrauterine period and have a relatively low incidence. Fetal ovarian cysts are the most common form diagnosed prenatally or immediately after birth. The pathophysiology of the development of these types of tumors is not fully elucidated, with ovarian hyperstimulation caused by maternal and placental hormones being the most accepted hypothesis. During intrauterine development, the diagnosis of fetal ovarian cysts is most often made accidentally during usual check-up ultrasounds corresponding to the first, second, and third trimesters of pregnancy. We conducted a scoping review with the aim to map the current knowledge regarding the treatment of fetal ovarian cysts diagnosed in the intrauterine period. Focusing on the articles published in the last 10 years in the specialized literature, we tried to identify a conceptualization regarding the surveillance and treatment of these anomalies.

Incisional hernia (IH) is a postoperative defect of the abdominal wall through which the contents of the peritoneal cavity are externalized beneath the skin in a peritoneal sac. IH differs in anatomic complexity, but also in its associated comorbidities and surgical history. As IH enlarges, complications occur and these become part of its natural history. The goal of the study is to review the impact of loss of domain upon abdominal wall before and after abdominal wall reconstruction. The absence of anatomical and functional linea alba leads to a combination of muscular disturbances, chronic respiratory and gastrointestinal conditions, and psychosocial issues. The pathophysiological changes are also due to the decrease of the intra-abdominal pressure (IAP). During repair, the sudden reintroduction of the viscera into an unprepared cavity leads to a sudden increase in cavity volume and an increase in IAP with fatal pathophysiological implications. For an optimal repair, preoperatively, the abdominal wall must be augmented by achieving the following objectives: reducing the volume of the sac contents, optimizing compliance, enlargement of the container. At the same time, for the optimal repair, the following must be taken into account: increased knowledge about this condition to manage systemic and local changes, CT scan evaluation, monitoring IAP, plateau pressure (PP), and Positive End Expiratory Pressure (PEEP). In conclusion, the goals can be achieved by systemic optimization with a multidisciplinary team, using Preoperative Progressive Pneumoperitoneum (PPP) and/or Botox (BTX), and abdominal wall reconstruction through a mesh with augmented component separation technique.

Background: The treatment of incisional hernias has radically changed over the last 50 years due to the introduction of mesh repair, which has been proven to be superior to tissue repairs in terms of recurrence. Severe complications such as bacterial contamination, enteral fistulas and severe visceral adhesions are the bane of mesh repair and lead to great challenges as far as treatment is concerned. Methods: From January 2009 to December 2018, we retrospectively collected operative and outcome data on reoperation following septic complications of incisional hernias (IH) mesh repair in 89 patients. For adjustment, comorbidities, mesh location, prognostic nutritional index (PNI) and operative time were included in an SPSS data analyzer. Results: in the referred interval 89 patients (29 males) met the inclusion criteria. The mean time for the onset of infections 15.04+-0.95 months and the number of previous abdominal interventions varied from 1 to 5. Wound infections were reported to be the primary factor for mesh infection. Following removal only 43% of meshes were found to be positive for bacterial infections; the most common species detected being , MRSA and, . Different techniques of mesh removal and abdominal wall closure were used. After abdominal wall closure, 54% of patients developed post-operative complications with a mortality of 12%. Conclusion: The risk of infection after abdominal wall reconstruction (AWR) appears to be higher than other clean abdominal procedures. Mesh removal is mandatory when the infection prolonged over 3 months. The procedure is associated with a high rate of morbidity and mortality and with low quality of life if the abdomen can't be closed. Prevention is the best treatment option.

BACKGROUND: Both umbilical and epigastric hernias may be associated with rectus muscle divarication. In such cases, isolated repair of combined hernia defects can have high recurrence rates and poorer cosmetic outcomes, thus the repair of both pathologies ought to be favored. The goal of the study below is to provide detailed technical aspects of the endoscopic retro-rectus mesh repair. METHODS: We chose a group of 16 patients who underwent the repair of ventral hernias associated with both primary and incisional rectus diastasis, using the extended-view of a totally extraperitoneal Rives-Stoppa repair (eRives) technique. All defects were < 6 cm in width. Our outcome measures perioperative complications and early recurrences. RESULTS: The approach used in our study has led to zero cases of perioperative complications and only one early recurrence. CONCLUSIONS: We believe that the e-Rives repair is the optimal approach for ventral hernias associated with diastasis recti. This technique additionally produces favorable cosmetic outcomes that granted our results a well-deserved recognition in the medical literature.

Background: complex groin hernia is a well describe entity with a high risk of recurrence and postoperative complications. There is no standardized approach and no reports to confirm the efficcacy of a surgical procedure. Our goal was to compare Lichtenstein repair (LR) as "golden standard" for open anterior approach with the transinguinal preperitoneal plasty (TIPP) in the treatment of complex groin hernia repair. Material and methods: the study was a prospective one and includes all patients with complex hernias admitted in the Department of Surgery of the Military Hospital Cluj-Napoca between January 2010 and December 2014. All the patients were randomized in two groups: LR and TIPP. Baseline characteristics, intraoperative findings, pain and complications were recorded. Follow-up was at least 1 year. The main outcome after 1 year were recurrence, chronic pain and its intensity recorded on VAS scale. Results: 205 patients (101 in LR group and 104 in TIPP) were included in the study. There were no differences in baseline characteristics and operative findings. Postoperative pain was lower for TIPP group (p 0.05). Follw-up was 98% at 1 month, 74% after 6 months and 64% after 1 year. Recurrence rate was higher for LR (p=0.027). Pain was increased in LR group. Conclusion: TIPP is equal in terms of chronic pain and recurrence for complex groin inguinal hernias.

Background: complex ventral hernia repair is a frequent and challenging topic. Reconstructive techniques are numerous but most of them are unable to achieve the goals of hernioplasty. Posterior component separation with transverses abdominis muscle release (TAR) is a novel approach that offers a solution for complex ventral hernias. METHOD: The posterior rectus sheath is incised and the retrorectus plane is developed. In a modification of the Rives-Stoppa technique, the transversus abdominis is released medial to the linea semilunaris to expose a broad plane that extends from the central tendon of the diaphragm superiorly, to the space of Retzius inferiorly, and laterally to the retro-peritoneum. This preserves the neurovascular bundles innervating the medial abdominal wall. Mesh is placed in a sublay fashion above the posterior layer. In an overwhelming majority of patients, the linea alba is reconstructed, creating a functional abdominal wall with wide mesh reinforcement. Results: Between November 2014 and July 2016 we used this procedure in 24 patients (14 males) with large median ventral incisional hernias. The recurrence in various degrees was present in 18 patients (75%). The average size of the defect was 18,3 cm. in width (12 to 28 cm.). Five patients (21%) developed various wound complications requiring reoperation. Follow-up between 2 and 18 months (11,8 months) without recurrence. CONCLUSION: TAR seems to be the "ideal" approach for complex hernias with good immediate outcomes.
