Complicated anorectal sepsis: Validation of scoring system for predicting anorectal sepsis severity

Anorectal sepsis is a common and potentially serious medical condition characterized by infection and inflammation of the anal canal and surrounding tissues. However, the lack of standardized and comprehensive scoring systems specifically tailored for predicting the severity of anorectal sepsis poses challenges in clinical practice. This study aimed to develop and validate a scoring system for predicting the severity of anorectal sepsis by incorporating relevant patient factors. A retrospective cohort study was conducted at Mansoura University Hospital, a tertiary care center, over a period of 5 years. The study population consisted of 330 patients diagnosed with anorectal sepsis during the study period. A scoring system was developed using multiple variables, with each variable assigned a specific score based on its clinical significance and weight in predicting disease severity. The developed scoring system's predictive performance was evaluated using receiver operating characteristic (ROC) analysis, calculating the area under the ROC curve to assess discriminative ability. Descriptive statistics were used to summarize the demographic and clinical characteristics of the study population. Chi-square tests or t tests were performed to assess differences between non-severe and severe anal sepsis groups. The scoring system consisted of 12 variables, with a maximum total score of 18. The logistic regression analysis revealed significant associations between localized swelling, presentation within 72 hours, multiple drainage sessions, and severe anorectal sepsis. The ROC analysis showed an area under the curve of 0.85, indicating good discriminative ability of the scoring system. The scoring system was developed and validated in a single center, which may limit its generalizability to other settings. The scoring system demonstrated good predictive performance and can be a valuable tool for clinicians in assessing disease severity, guiding treatment decisions, and identifying high-risk patients.

Comparing stapler and sutured mesh fixation techniques for laparoscopic TAPP repair: a study on chronic groin pain on 3-year follow-up

Trans-abdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) repairs are the available surgeries for inguinal hernias, with both methods of laparoscopic repairs requiring mesh applications. This study analyzes the correlation between sutured versus stapler mesh fixation in a laparoscopic TAPP for unilateral groin hernia regarding chronic pain during 3-year follow-up. A total of 130 patients with laparoscopic hernia undergoing TAPP repair were randomized into 2 groups based on their fixation technique-one with sutures and the other with stapler. Postoperative complications and chronic groin pain were noted for each technique. Equal number of participants was present in the stapler and suture groups, with the majority having an ASA score of one. The mean age was 42.50 ± 13.86 years, and the body mass index (BMI) was 27.47 ± 5.88. The stapler group presented a shorter mean operative time than the suture group. However, the stapler group had a significantly higher mean VAS score than the suture group. Most participants in the suture group (89.2%) had LOS for 1 day, while a 2-day LOS was significantly higher in the stapler group (12.3%) than in the suture group (9.2%). No patient reported mesh erosion, conversion, recurrence, testicular atrophy, and mesh infection. Early postoperative pain was more in stapler group along with long hospital stay, but both were non-significant. Chronic postoperative pain results and recurrence incidences over 3-year follow-up were also similar. Re-admission rates were minimal, no significant complications occurred.

Staple Line Reinforcement Using SEAMGUARD® versus Suture Over Sewing During Laparoscopic Sleeve Gastrectomy for Super Morbidly Obese Patients: A Prospective Randomized Clinical Trial

Itroduction: Although theoretically a simple procedure, laparoscopic sleeve gastrectomy (LSG) can be followed by life-threatening complications. Early postoperative complications include staple line bleeding and leakage. Staple line reinforcement (SLR) has been used to decrease these complications. There are various methods for reinforcement of staple line such as suture over sewing, placing omental flap, using buttressing material, and spraying fibrin glue along the staple line. However, it is controversial whether SLR reduces the rate of staple line complications or not.

MATERIALS AND METHODS

A prospective randomized clinical trial included 200 super morbidly obese patients randomized into two groups: Group 1 with reinforcement of the staple line by SEAMGUARD® (Gore Medical, Newark, Delaware) and Group 2 with reinforcement of the staple line using suture over sewing.

RESULTS

The mean operative time was significantly shorter in Group 1 than Group 2 (62.6 ± 14.5 vs. 84.7 ±15.8 min, p=0.02). Intraoperative blood loss was significantly lower in Group 1 than Group 2 (17.1± 19.1 vs. 56.8 ± 27.9ml, p=0.00). Staple line hematomas were significantly higher in Group 2. There was no difference in postoperative bleeding between the two groups. No leak was reported in both groups. The cost was higher in Group 1.

CONCLUSION

Reinforcing the staple line in laparoscopic sleeve gastrectomy using suturing is equal to SEAMGUARD® in all aspects except shorter operative time and lower intraoperative blood loss with SEAMGUARD®.

Angiotensin-converting enzyme insertion/deletion gene polymorphism in Egyptian children with systemic lupus erythematosus: a possible relation to proliferative nephritis

Introduction Angiotensin-converting enzyme (ACE) is crucial in the pathogenesis of systemic lupus erythematosus through angiotensin II which regulates vascular tone and endothelial functions. Objectives To study the frequency of ACE insertion/deletion (I/D) gene polymorphism in Egyptian children with systemic lupus erythematosus and its possible relation to the renal pathology in cases with lupus nephritis. Subjects and methods The frequency of ACE gene insertion/deletion polymorphism genotypes was determined in 78 Egyptian children with systemic lupus erythematosus and compared to a matched group of 140 healthy controls using polymerase chain reaction. Results The DD genotype of the ACE gene was higher in systemic lupus erythematosus patients when compared to controls ( P<0.0001; odds ratio (OR) 2.4; 95% confidence interval (CI) 1.7-3.3) and the D allele was more frequent than the I allele in systemic lupus erythematosus patients in comparison to controls ( P < 0.0001; OR = 2.2; 95% CI = (1.6-3.1). In the lupus nephritis group, the DD genotype was significantly higher in those with proliferative lupus nephritis when compared to those with non-proliferative lupus nephritis ( P = 0.02; OR = 1.45; 95% CI = 1.4-1.6). Also, patients with proliferative lupus nephritis showed a higher frequency of the D allele ( P < 0.001; OR = 1.98; 95% CI = 1.3-2.9). Conclusion The D allele and DD genotype of the ACE gene appear to be a risk factor for the susceptibility of systemic lupus erythematosus and occurrence of proliferative nephritis in Egyptian children.

Clinical relevance of serum vascular endothelial growth factor and interleukin-6 in patients with colorectal cancer

BACKGROUND/AIM

Some biological factors play a role in stimulation of malignant growth, metastasis and angiogenesis; however, their clinical relevance has not yet been well established for most of them. This work was aimed at studying the clinical relevance of serum vascular endothelial growth factor (VEGF) and interleukin-6 (IL-6), in patients with colorectal cancer (CRC).

MATERIALS AND METHODS

Preoperative serum levels of VEGF and IL-6 were measured by enzyme-linked immuno-assay in 35 CRC patients and in 30 healthy controls.

RESULTS

CRC patients with or without metastasis had significantly higher VEGF and IL-6 levels than healthy controls (all P < 0.001). Patients with advanced clinical stage had significantly higher levels of VEGF and IL-6 than those with early clinical stage (all P < 0.001). Also, patients with metastatic disease had significantly higher VEGF and IL-6 levels than those with localized disease (all P < 0.001). The diagnostic accuracy for invasiveness was 83% for VEGF (cut off value = 240 pg/ml) and 66% for IL-6 (cut off value = 6.7 pg/ml), with sensitivity 79% and 74% and specificity 68% and 59%, respectively.

CONCLUSION

In CRC patients, preoperative measurement of serum VEGF and Il-6 may prove useful non-invasive diagnostic indicators associated with advanced clinical stage and tumor metastasis that warrants further investigations.
