Background: Postoperative pancreatic fistula (POPF) is a major complication of distal pancreatectomy (DP). Although the visceral fat area (VFA) is a risk factor for POPF in DP, its measurement is complicated. This study aimed to identify a simple marker as a predictive indicator of POPF.

Methods: We included 210 patients who underwent resection at our institution between 2020 and 2023. The patients' characteristics, preoperative laboratory data, and radiographic findings (e.g., portal vein distance and VFA) and their association with pancreatic fistula after DP were analyzed. POPF was defined as Grade B or C pancreatic fistula on the basis of the International Study Group of Pancreatic Surgery 2016 consensus.

Results: POPF developed in 82 (39.0%) patients. Univariate analysis showed that female sex, pancreatic thickness of the cutting line, operative time, blood loss, C-reactive protein (CRP) level on postoperative day (POD) 3, drain amylase level on POD 3, VFA, and the peritoneum to portal vein distance (PPD) were associated with POPF. Receiver operating characteristic curve analysis of PPD showed a higher area under the curve than VFA (cutoff for PPD: 68 mm). Multivariate analysis showed that CRP (odds ratio [OR]: 2.214), drain amylase (OR: 2.875), and PPD (OR: 15.538) were independent risk factors. When we compared the DP fistula risk score and PPD, receiver operating characteristic analysis showed areas under the curve of 0.650 and 0.803, respectively.

Conclusions: A PPD of ≥68 mm is a useful risk predictor of POPF. Determining this distance is simple and easily applicable in the clinical setting.

Purpose: This study aimed to evaluate the feasibility, safety, and efficacy of laparoscopic transabdominal preperitoneal hernia repair (TAPP) for inguinal hernias in emergency settings, providing insights from a long-term follow-up.

Methods: We retrospectively analyzed all patients who underwent emergency TAPP repair in ASST Nord Milano from January 2005 to December 2023. A prospectively collected database of 54 consecutive TAPP hernia repairs was reviewed. The study evaluated the feasibility and safety of TAPP through operative time and the conversion rate. Effectiveness was gauged by recurrence and complication rates as well as acute and chronic pain using the Visual Analog Scale (VAS). Long-term follow-up included assessing recovery to normal activity.

Results: Overall, data from 54 consecutive patients were analyzed. Median age was 72 (IQR = 11), with 21 men and 33 women (38.8% vs. 61.2%). The primary diagnosis was a primary hernia (61.1%), while a recurrent type was identified in 21 patients (38.9%). Femoral hernia was identified in 36 cases (48%). The median operative time was 100 min (IQR = 53 min) with 6 cases of conversion (11.1%). One recurrence (1.85%) was noted and the complication rate was 5.55 %. At a median follow-up of 38 months, there was a low grade of chronic pain (VAS 3) in a patient (1.85%) and one recurrence (1.85%).

Conclusion: TAPP is a safe, feasible, and effective option for emergency inguinal hernia repair, exhibiting low complication and recurrence rates on long-term follow-up when performed by surgeons with minimally invasive surgery experience and in selected patients.

Introduction: Pediatric ostomy creation is becoming increasingly prevalent in Sub-Saharan Africa (SSA). The procedure is associated with both physical and ethical challenges for patients, their families, and medical providers.

Ethical discussion: Counseling parents of children in need of ostomy creation must address each of their trepidations while seeking to promote the ethical tenets of beneficence, non-maleficence, autonomy, quality of life, and justice.

Conclusion: As pediatric surgical care in SSA continues to progress, efforts to ameliorate challenges to providing holistic patient-centric care must also progress. This manuscript outlines ethical dilemmas associated with pediatric ostomy care in SSA and lists efforts and initiatives seeking to address them.

Background: The aim of this study was to systematically retrieve and evaluate published risk prediction models for autogenous arteriovenous fistula (AVF) failure post-formation in maintenance hemodialysis (MHD) patients, with the goal of assisting healthcare providers in selecting or developing appropriate risk assessment tools and providing a reference for future research.

Methods: A systematic search of relevant studies was conducted in PubMed, Web of Science, Cochrane Library, CINAHL, Embase, CNKI, Wanfang Database, VIP Database, and CBM Database up to February 1, 2024. Two researchers independently performed literature screening, data extraction, and methodological quality assessment using the Prediction Model Risk of bias (ROB) Assessment Tool.

Results: A total of 4869 studies were identified, from which 25 studies with 28 prediction models were ultimately included. The incidence of autogenous AVF failure in MHD patients ranged from 3.9% to 39%. The most commonly used predictors were age, vein diameter, history of diabetes, AVF blood flow, and sex. The reported area under the curve (AUC) ranged from 0.61 to 0.911. All studies were found to have a high ROB, primarily due to inappropriate data sources and a lack of rigorous reporting in the analysis domain. The pooled AUC of five validation models was 0.80 (95% confidence interval: 0.79-0.81), indicating good predictive accuracy.

Conclusion: The included studies indicated that the predictive models for AVF failure post-formation in MHD patients are biased to some extent. Future research should focus on developing new models with larger sample sizes, strict adherence to reporting procedures, and external validation across multiple centers.

Background: The convergence of the economic crisis, COVID-19 pandemic, and Beirut Blast has precipitated unprecedented challenges for the healthcare system in Lebanon, particularly for cancer patients. Amidst these crises, our study evaluates its contribution to a concerning trend of operating on more late-stage and complex colorectal cancer (CRC) cases.

Methods: We included 155 patients operated for CRC between 2017 and 2023. Patients age; sex; operation type (emergency or elective); tumor size, grade, and location; tumour, node, metastasis stage; lymphatic, vascular and perineural invasions; American Society of Anesthesiologists (ASA) score, presentation and previous history, and complications were examined.

Results: Surgical outcomes remained relatively consistent before and after the crisis. However, there was a notable increase, with patients being 3.59 times more likely to undergo resection of adjacent organs in metastatic disease post-crisis. Patient characteristics also exhibited notable shifts, with a 9.60-fold increase in the likelihood of having an ASA score of at least 2 after the crisis. Additionally, there was a 5.36-fold decrease in the odds of patients undergoing a colonoscopy before their diagnostic one post-crisis. Preoperative carcinoembryonic antigen levels were significantly elevated post-crisis compared to pre-crisis levels. Pathological findings revealed increased odds of perineural, vascular, and lymphatic invasion post-crisis. Additionally, there was a notable increase in the likelihood of hepatic synchronous metastases post-crisis. Furthermore, a trend to operate on complicated diseases was noted with an increased number of colostomies.

Conclusion: The economic crisis in Lebanon has profoundly affected early intervention and comprehensive treatment for CRC patients, resulting in a concerning rise in late-stage cases requiring surgical intervention.

Introduction: The United Kingdom Registry of Endocrine and Thyroid Surgery (UKRETS) holds the largest database of pediatric parathyroidectomy cases globally. There are currently no quoted acceptable cure or complication rates in the literature.

Methods: This retrospective database analysis evaluates the efficacy and safety of targeted parathyroidectomy (tPTx) and bilateral neck exploration (BNE) in first-time parathyroidectomy for pediatric primary hyperparathyroidism (PHPT) through analysis of the UKRETS database (1995-2022). Pre-, intra- and postoperative outcomes were assessed and analyzed.

Results: 168 cases underwent parathyroidectomy; 25 (15%) familial and 143 (85%) sporadic PHPT. 69% were female with a mean age of 10 years (Range 0-17). BNE was the most common operative approach (61%; n = 103/168). The most frequently used imaging modality was US (80%; n = 135/168). Mean number of glands excised in familial cases was three compared to one gland in sporadic cases (p < 0.05). Familial cases had a significantly higher rate of postoperative hypocalcemia (32% vs. 9%, p < 0.05) and all were BNE. Cure rate was 96.9% (n = 127/131), with differences in cure rates that did not reach statistical significance (sporadic 98.2% vs. familial 90.5%, p = 0.06). Preoperative localization (image-positive or negative) made no difference to cure rates in either familial (90% vs. 91%, p = 0.94) or sporadic (97.5% vs. 100%, p = 0.4) cases.

Conclusions: This analysis demonstrates that first-time pediatric parathyroidectomy for PHPT is safe and effective. Familial cases have a higher rate of postoperative hypocalcemia; therefore, parents should be informed of this when consented. Targeted parathyroidectomy is safe and effective in both sporadic and familial cases, as long as there is positive preoperative imaging.

Objectives: This study aimed to conduct a retrospective study to identify inflammatory biomarkers for predicting ventilator-associated pneumonia in elderly patients.

Methods: Our retrospective study included 265 elderly patients (age ≥60 years) undergoing abdominal surgery with tracheal intubation and general anesthesia, with 93 experiencing varying degrees of ventilator-associated pneumonia during hospitalization, and 172 without. Serum concentrations of serum amyloid A (SAA), toll-like receptor 4 (TLR4), and soluble myeloid triggering receptor 1 (sTREM-1) were measured at 24 h post-operation using enzyme-linked immunosorbent assay. Comparisons of SAA, TLR4, and sTREM-1 and other risk factors at 24 h post-operation between elderly patients with and without ventilator-associated pneumonia were performed.

Results: The study revealed a 35.1% incidence of postoperative ventilator-associated pneumonia among elderly patients. Upregulations of SAA, TLR4, and sTREM-1 were observed in patients with ventilator-associated pneumonia. Chronic obstructive pulmonary disease, smoking, and tracheal intubation were identified as independent risk factors. The joint prediction model was demonstrated with superior predictive accuracy (area under the curve = 0.89) compared to individual biomarkers. Correlations with procalcitonin further supported the predictive potential of SAA, TLR4, and sTREM-1 in an inflammatory response.

Conclusions: SAA, TLR4, and sTREM-1, particularly when combined, serve as valuable prognostic indicators for postoperative ventilator-associated pneumonia in elderly patients undergoing abdominal surgery with tracheal intubation and general anesthesia. The joint prediction model offered a promising tool for early risk assessment.

Introduction: Uncomplicated surgical approaches that minimize anastomotic complications while improving revisional metabolic/bariatric surgical (MBS) outcomes are needed.

Methods: This prospective single-center study assessed the feasibility, safety, and efficacy of the novel linear magnetic anastomosis system (LMAS [3 cm]) in performing a side-to-side duodeno-ileostomy (MagDI) bipartition to revise clinically suboptimal primary sleeve gastrectomy (SG). Patients with severe obesity with/without type 2 diabetes (T2D) with suboptimal weight loss, regain, and/or T2D recurrence post SG underwent revisional MagDI. A distal and proximal magnet were delivered endoscopically to the ileum and duodenum and aligned via laparoscopic assistance. Gradual magnet fusion formed a DI bipartition.

Primary endpoints: technical feasibility, safety (Clavien-Dindo [CD] severe adverse event classification) at 1 year. Secondary endpoints: MBS weight and T2D reduction.

Results: July 29, 2022-March 28, 2023, 24 patients (95.8% female, mean age 44.9 ± 1.5 years, and body mass index [BMI] 39.4 ± 1.3 kg/m²) underwent MagDI. Feasibility was attained via correct magnet placement (mean operative time 63.5 ± 3.3 min), patent anastomoses created, and magnet passage per anus in 100.0% of patients. There were 4 CD-III mild or moderate severe AEs, 0.0% associated with the LMAS or MagDI: 0.0% anastomotic leakage, obstruction, bleeding, infection, reintervention, or death. Mean BMI reduction was 2.1 kg/m² (p < 0.05); total weight loss 5.3%, excess weight loss 16.4%; and the patient with T2D improved.

Conclusion: The single-anastomosis MagDI procedure using the novel 3-cm LMAS to revise clinically suboptimal SG was technically straightforward, incurred no major complications, mitigated weight regain, and renewed clinically meaningful weight loss.

Objectives: Deprivation is a complex, multifaceted concept and not synonymous with poverty. The aim of this study was to assess the prognostic influence of the multiple deprivation index on emergency laparotomy (EL) outcome.

Methods: STROCSS statement standards were followed to conduct a retrospective cohort study. Consecutive 1723 adult patients [median age (range): 66 (18-98), 762 M, and 961 F] undergoing EL over eight years (2014-22) at two hospitals [a tertiary teaching center and district general hospital (DGH)] were studied. Deprivation scores and ranks were derived from patients' postcodes using the Welsh Index of Multiple Deprivation and ranks categorized into quartiles. Primary outcome measure was a 30-day operative mortality (OM).

Results: OM risk was higher in the most deprived quartile (Q1) compared with the least deprived quartile (Q4) (13.2% vs. 7.9% and p = 0.008). Deprivation was an independent predictor of OM on both univariate (unadjusted OR: 1.75, 95% CI 1.17-2.61, and p = 0.006) and multivariable logistic regression analyses (OR: 1.03, 95% CI 1.01-1.06, and p = 0.023; adjusted for age ≥80 years, American Society of Anesthesiologists grade, need for bowel resection, and peritoneal contamination). Deprivation had poor discriminatory value in predicting OM (AUC: 0.56 and 95% CI 0.54-0.59). Subgroup analysis showed that although the risk of OM was lower in the tertiary center compared with the DGH (7.9% vs. 14.5% and p < 0.001), the predictive significance of deprivation was similar in both hospitals (AUC: 0.54 vs. 0.56 and p = 0.674).

Conclusion: Deprivation is an independent but modest predictor of OM after EL. The potential prognostic value of incorporating deprivation into preoperative risk assessment algorithms deserves further evaluation.

Background: Incisional complications of groin after inflow or infrainguinal bypasses with prosthetic conduits can result in major morbidities that require reoperation, infected graft removal, and limb loss. Muscle flaps are typically performed to treat groin wound complications, but they are also done prophylactically at the time of index procedures in certain high-risk-for-poor-healing patients to mitigate anticipated groin wound complications. We used a nationwide multi-institutional database to investigate outcomes of prophylactic muscle flaps in high-risk patients who underwent prosthetic bypasses involving femoral anastomosis.

Methods: We utilized ACS-NSQIP database 2005-2021 to identify all elective inflow and infrainguinal bypasses that involve femoral anastomoses. Only high-risk patients for poor incisional healing who underwent prosthetic conduit bypasses were selected. A 1:3 propensity-matching was performed to obtain two comparable studied groups between those with (FLAP) and without prophylactic muscle flaps (NOFLAP) based on demographics and comorbidities. 30-day postoperative outcomes were compared.

Results: Among 35,011 NOFLAP, 990 of them were propensity-matched to 330 FLAP. There was no significant difference in 30-day mortality, MACE, pulmonary, or renal complications. FLAP was associated with higher bleeding requiring transfusion, longer operative time, and longer hospital stay. FLAP also had higher overall wound complications (15.2% vs. 10.6%; p = 0.03), especially deep incisional infection (4.9% vs. 2.4%; p = 0.04).

Conclusion: Prophylactic muscle flap for prosthetic bypasses involving femoral anastomosis in high-risk-for-poor-healing patients does not appear to mitigate 30-day wound complications. Caution should be exercised with this practice and more long-term data should be obtained to determine whether prophylactic flaps decrease the incidence of graft infection.
