Is the use of endoloops safe and efficient for the closure of the appendicular stump in complicated and uncomplicated acute appendicitis?

INTRODUCTION: There is still controversy regarding the ideal technique to close the appendicular stump in laparoscopic appendectomy (LA). The objective of this study was to determine the safety and efficiency of the use of an endoloop (EL) and endostapler (ES) in complicated and uncomplicated acute appendicitis. METHODS: Retrospective cohort study of patients undergoing LA from February 2013 to December 2019. Acute uncomplicated and complicated appendicitis were analysed separately, establishing two groups according to the stump closure technique: EL or ES. Seven hundred-nine patients were included (535 uncomplicated and 174 complicated). In uncomplicated appendicitis, an EL was used in 447 of the patients (83.55%) and an ES was used in 88 patients (16.45%). In complicated appendicitis, an EL was used in 85 patients (48.85%) and an ES was used in 89 patients (51.15%). An analysis of effectiveness and a cost analysis of each technique were performed. RESULTS: In uncomplicated appendicitis, we found no differences with respect to global complications, although there were significant differences in the total mean hospital stay (EL group 1.55 (SD 1.48) days; ES group 2.21 (SD 1.69) days; p = 0.046). This meant a savings of 514.12€ per patient using the EL p < 0.001). In complicated appendicitis, the reoperations classified as Clavien-Dindo IIIB in the EL group (6.4%) were greater than in the ES group (0%) (p = 0.012), although the rate of postoperative abscesses (p = 0.788) and the mean volume of abscesses (p = 0.891) were similar. CONCLUSION: The systematic use of an EL could reduce costs in uncomplicated appendicitis, while in complicated cases, both options are valid. Prospective studies with a greater number of patients are needed to observe differences in postoperative complications.

Torsion of wandering spleen: radiological findings.

Wandering spleen (or ectopic spleen) is a rare anomaly resulting from hyperlaxity or even absence of the ligaments that hold the spleen in its anatomical position. Although more frequently a congenital condition, it can also be acquired. Torsion of the vascular pedicle is its potential main complication with subsequent development of splenic infarct. In this paper we will describe the pathogenesis, clinical manifestations, treatment options and radiological findings which allow the diagnosis of this entity.

Laparoscopic vs. Open Approach in Emergent Inguinal Hernia: Our Experience and Review of Literature.

There is currently no consensus or homogeneous recommendation about the role of the laparoscopic approach in emergent inguinal hernia surgery. The aim of this manuscript is showing our experience and results of laparoscopic approach for emergent groin hernia repair comparing with open approach. A retrospective review of a prospectively maintained database between January 2011 and December 2021 of acute incarcerated groin hernia that were operated at Virgen del Rocio University Hospital. In this period, they were identified 463 patients with groin hernia that required an emergency repair. 454 patients underwent open surgery (group 1) and 36 patients underwent laparoscopic approach (TAPP procedure) (group 2). Median length stay was 1 day in lap group and 2 days in open approach. Reintervention was necessary in 20 cases (4.40%) from group 1 and one (2.27%) from group 2. In laparoscopic approach, no mortality was described but in open approach, 10 patients (2.20%) died. Globally, 58 cases (12.77%) from group 1 and six patients (16.66%) from group 2 presented any complication. Wound infection was higher in group of open repairs (5.94% vs. 2.77%). Non-surgical complications were higher in open approach (19 vs. 0). There is no statistical significance in any of these items. Laparoscopic approach is a safe, feasible and effective therapeutic option for the treatment of incarcerated groin hernia that require emergency surgery, but prospective and randomized comparative studies are needed to establish the best approach.

Personalized additive manufacturing of devices for the management of enteroatmospheric fistulas.

Additive manufacturing techniques allow the customized design of medical devices according to the patient's requirements. Enteroatmospheric fistula is a pathology that benefits from this personalization due to its extensive clinical variability since the size and morphology of the wound differ extensively among patients. Standard prosthetics do not achieve proper isolation of the wound, leading to a higher risk of infections. Currently, no effective personalized technique to isolate it has been described. In this work, we present the workflow for the design and manufacture of customized devices adapted to the fistula characteristics as it evolves and changes during the treatment with Negative Pressure Wound Therapy (NPWT). For each case, a device was designed with dimensions and morphology depending on each patient's requirements using white light scanning, CAD design, and additive manufacturing. The design and manufacture of the devices were performed in 230.50 min (184.00-304.75). After the placement of the device, the wound was successfully isolated from the intestinal content for 48-72 h. The therapy was applied for 27.71 ± 13.74 days, and the device was redesigned to adapt to the wound when geometrical evolutionary changes occur during the therapy. It was observed a decrease in weekly cures from 23.63 ± 10.54 to 2.69 ± 0.65 (p = 0.001). The fistulose size was reduced longitudinal and transversally by 3.25 ± 2.56 cm and 6.06 ± 3.14 cm, respectively. The wound depth also decreased by 1.94 ± 1.08 cm. In conclusion, customization through additive manufacturing is feasible and offers promising results in the generation of personalized devices for the treatment of enteroatmospheric fistula.

Long-term influence of frailty in elderly patients after surgical emergencies.

PURPOSE: Frailty is known to increase vulnerability to stressful factors, and motivate a higher morbidity and mortality in several health conditions. However, long-term impact of frailty after surgical procedures remains unclear. The purpose of this study was to evaluate the relationship between frailty and long-term clinical outcomes after emergency surgery. METHODS: Prospective cohort study in patients older than 70 years undergoing emergency procedures. A total of 82 patients (mean age 78.5 years, 53.3% women) were consecutively enrolled. Data on demographics, surgical procedures, complications after 30 postoperative days, and frailty according to the clinical frailty scale, Triage Risk Screening Tool (TRST), and FRAIL scale were recorded. Readmission, mortality, and transition to frailty rates were analyzed at 6 and 18 months postoperatively. RESULTS: The prevalence of frailty ranged between 14.6 and 29.6% depending on the scale used. The overall mortality rate at 18 months was 19.5% (16 patients), and the survival curves demonstrated a significant difference in mortality between frail and non-frail patients assessed using the FRAIL scale and TRST (p = 0.049 and p = 0.033, respectively), with a hazard ratio of 2.28 (95% confidence interval 1.24-6.44). Logistic regression analysis showed that diabetes (p = 0.013) was an independent risk factor for transition to frailty, and antidepressant drug use was close to statistical significance (p = 0.08). CONCLUSION: Frailty is a predictive marker of long-term mortality in patients undergoing emergency procedures. Diabetes and depression may represent independent risk factors for transition to frailty over time.

Using a bio-scanner and 3D printing to create an innovative custom made approach for the management of complex entero-atmospheric fistulas.

Enteroatmospheric fistulae are challenging clinical conditions that require surgical expertise and that can result in chronic debilitating conditions placing the patient in a vicious cycle characterized by non healing wounds and malnutrition. They are a complex entity that presents great variability depending on the number, shape, and size of the fistulous orifices, their debit, and the dimensions of the wound. This means that, at present, there is no device that adapts to the anatomical characteristics of each patient and manages to control the spillage of intestinal effluvium from the wound. The aim of this study is to describe the manufacturing technique and to assess the preliminary results of a custom device designed through bioscanner imaging and manufactured using 3D printing for use with negative pressure wound therapy (NPWT) in the management of enteroatmospheric fistula. A proof of concept is given, and the design of the device is presented for the first time. After obtaining images of each fistula with a bioscanner, a personalised device was designed for each patient by 3D printing shape of a prism and a hollow base, taking into account the dimensions of the fistulous area in order to perform a floating ostomy to isolate the wound from the debit enteric. The polycaprolactone (PCL) device was placed including inside the fistulous surface and surrounding it with the NPWT system in order to accelerate wound healing.

Acute appendicitis during pregnancy: differences in clinical presentation, management, and outcome. / Diferencias en la presentación clínica, manejo y resultados de la apendicitis aguda en el embarazo.

OBJECTIVES: To analyze the clinical presentation, management, and outcome of acute appendicitis (AA) in pregnant and nonpregnant women of childbearing age. MATERIAL AND METHODS: Descriptive study of 2 cohorts of women (pregnant -P- and nonpregnant -NP-). The women, who were matched according to risk factors, were included when they underwent an emergency appendectomy based on clinical suspicion of AA. We recorded age, medical history, clinical presentation, management, and outcome. Pregnant women were classified according to gestational age of the fetus (trimester). RESULTS: . We included 153 women (51 P, 102 NP). The mean (SD) age was 28.8 (6.5) years (P women, 29.7 [5.8] years; NP, 28.3 [6.8]; P=.242). The mean Alvarado score was 7.1 (1.6) (P, 6.7 [1.7]; NP, 7.3 [1.5]; P=.016). The rate of complicated AA was higher in P (19.6%) than NP (2.9%) women (P<.001). Pregnancy was also associated with higher rates of surgical wound infection (P, 14.0%; NP, 3.0%; P=.016) and a longer mean hospital stay (P, 5.1 [4.8] days; NP, 1.7 [1.0]; P<.001). In the third trimester of P, poorer outcomes were recorded in relation to these risks (P=.031; P=.003, and P<.001, respectively). CONCLUSION: The atypical clinical presentation of AA during pregnancy makes diagnosis difficult and may lead to a higher incidence of complicated AA and surgical wound infection as well as longer hospital stays, particularly when AA presents in the third trimester.

OBJETIVO: Evaluar la presentación clínica, el manejo y los resultados de la apendicitis aguda (AA) en mujeres de edad fértil en función de la presencia de embarazo y su estado evolutivo. METODO: Estudio observacional de dos cohortes (gestantes [G] y no gestantes [NG]), apareadas según técnicas de propensión de riesgo, que incluyó mujeres adultas en edad fértil sometidas a apendicectomía urgente por la sospecha clínica de AA. Se recogieron variables relacionadas con la edad, los antecedentes personales, la presentación clínica, el manejo y los resultados. Se realizó un análisis según la presencia de embarazo y el trimestre de gestación. RESULTADOS: Se incluyeron 153 mujeres (51 G y 102 NG). La edad media fue de 28,8 (DE 6,5) años (G: 29,7 [DE 5,8] vs NG: 28,3 [DE 6,8]; p = 0,242). La puntuación de la escala de Alvarado fue de 7,1 (DE 1,6) (G: 6,7 [DE 1,7] vs NG: 7,3 [DE 1,5]; p = 0,016). Las G presentaron mayor incidencia de AA complicada (G: 19,6% vs NG: 2,9%; p < 0,001), infección del sitio quirúrgico (G: 14,0% vs NG: 3,0; p = 0,016), estancia media (G: 5,1 [DE 4,8] vs NG: 1,7 [DE 1,0]; p < 0,001). Los resultados fueron peores, entre las G del tercer trimestre (p = 0,031, p = 0,003 y p < 0,001, respectivamente). CONCLUSIONES: La presentación clínica atípica de la AA durante el embarazo dificulta su diagnóstico, lo que podría traducirse en una mayor incidencia de AA complicada, infección del sitio quirúrgico y tiempo de estancia hospitalaria, sobre todo si se presenta la AA durante el tercer trimestre de gestación.

1000 consecutive liver transplants. Descriptive analysis and evolution of a single center. / 1000 trasplantes hepáticos consecutivos. Análisis descriptivo y evolución de un centro.

Between 1991 and 2013, 1,000 liver transplantations were performed at Virgen del Rocio Hospital (Seville, Spain). A retrospective study was conducted, analyzing the characteristics of recipients and donors, indications, surgical technique, complications and survival in 2 different stages (1991-2002 vs. 2003-2013) coinciding with the implementation of the MELD scale as a prioritization model. The most frequent indication were of hepatopathy of hepatocellular origin in 48.8%. There was a significant increase in the indications for hepatocarcinoma (8.6% and 24.1% P=0.03), and the rate of retransplantation (5.9% vs 9.6%, P=0.04). There was a change in the age of donation, going from 27.7 years in 1990 to 62.9 years in 2012 (P=0.001). The percentage of patients who did not require blood transfusion doubled (6.16 vs. 14.31%, P=.001). Survival of all patients after one, 5 and 10 years was 77, 63.5 and 51.3%, respectively.

Gastrointestinal stromal tumor (GIST) presenting as a groin mass mimicking and incarcerated hernia.

INTRODUCTION: The contents of a hernial sac can harbor preperitoneal fat, epiploon or some hollow viscera, with a malignant lesion in its interior being an unusual finding. PRESENTATION OF CASE: We present the case of a 59 year-old male who arrived in the Emergency Department with an irreducible inguinal hernia, with no local signs of vascular compromise. The diagnosis was made after examining the hernia sac, using an inguinal approach, showing evidence of a largely necrosed gelatinous mass, which was resected by mid-line infraumbilical laparotomy. The mass was diagnosed as a high risk gastrointestinal stromal tumor. DISCUSSION: GIST are characterized by the absence of symptoms in most cases. The unusual presentation, as incarcerated hernia, allowed the diagnosis of this disease. The tumor measured 6cm with a mitotic index greater than 5/50 CGA tumor is classified as high risk. The finding of a thickened peritoneum proceeded to opening. The exploration of the sac is critical. CONCLUSIONS: Exploring the hernia sac in any complicated hernia, especially when the sac has macroscopic alterations and presence of areas of bleeding inside is essential.
