[Late Open Semi-conversion with Endograft Preservation for (Type II) Endoleaks with Late Aneurysm Sac Enlargement after EVAR - Indications, Method and Results in Our Own Patient Collective]. / Die späte offene Semikonversion mit Prothesenerhalt bei (Typ II­)Endoleckagen mit spätem Aneurysmasackwachstum nach EVAR - Indikationen, Methode und Ergebnisse im eigenen Patientenkollektiv.

EVAR (endovascular aortic repair) is the most common method for treating an abdominal aortic aneurysm, but according to the latest findings it carries the risk of subsequent complications. These can be caused by (late) aneurysm sac growth. If conservative and surgical therapies fail to treat the aneurysm sac growth, open conversion is necessary to prevent aneurysm rupture. There are several options for open conversion, in which the EVAR prosthesis can be completely preserved or is (partially) removed. Late open semi-conversion with complete in-situ preservation of the EVAR-prosthesis and gathering of the aneurysm sac are a less invasive method than complete conversion and may be performed instead for selected patients. The aim of the present work is to present the surgical method, including indications and technical information, as well as the presentation of the results in our recent patient collective.All patients semi-converted in our department of vascular surgery and phlebology due to (type II) endoleak were included. All data are presented as n (%) or median (range).Between 6/2019 and 3/2023, 13 patients underwent semi-conversion 6 (2-12) years (median, range) after the initial EVAR. The aneurysm sac diameter at the time of semi-conversion was 69 mm (58-95 mm), the operating time was 114 min (97-147 min), the blood loss was 100 ml (100-1500 ml). Five (38%) patients received blood transfusion intraoperatively and 2 (15%) postoperatively. The stay in the intensive care unit lasted 1 (1-5) days, the hospitalisation time was 8 (6-11) days. Postoperative complications were intestinal atony (3 [23%], 1 [8%] with nausea/emesis and gastric tube insertion), anaemia (2 [15%]), hyponatraemia (2 [15%]), delirium (1 [8%]), COVID-19 infection (1 [8%]) and 1 [8%] intra-abdominal postoperative bleeding with the indication for surgical revision and the transfusion of 8 erythrocyte concentrates.Semi-conversion is a safe and practicable surgical method with few severe complications for a selected group of patients, which should be considered as an alternative to more invasive methods with (partial) removal of the EVAR-prosthesis. Further long-term studies comparing semi-conversion to full conversion are needed to demonstrate its benefits.

Closure of Temporary Ileostomy 2 Versus 12 Weeks After Rectal Resection for Cancer: A Word of Caution From a Prospective, Randomized Controlled Multicenter Trial.

BACKGROUND: The optimum timing for temporary ileostomy closure after low anterior resection is still open. OBJECTIVE: This trial aimed to compare early (2 wk) versus late (12 wk) stoma closure. DESIGN: The study included 2 parallel groups in a multicenter, randomized controlled clinical trial. SETTINGS: The study was conducted at 3 Swiss hospitals. PATIENTS: Patients undergoing low anterior resection and temporary ileostomy for cancer were included. INTERVENTIONS: Patients were randomly allocated to early or late stoma closure. Before closure, colonic anastomosis was examined for integrity. MAIN OUTCOME MEASURES: The primary efficacy outcome was the Gastrointestinal Quality of Life Index 6 weeks after resection. Secondary end points included safety (morbidity), feasibility, and quality of life 4 months after low anterior resection. RESULTS: The trial was stopped for safety concerns after 71 patients were randomly assigned to early closure (37 patients) or late closure (34 patients). There were comparable baseline data between the groups. No difference in quality of life occurred 6 weeks (mean Gastrointestinal Quality of Life Index: 99.8 vs 106.0; p = 0.139) and 4 months (108.6 vs 107.1; p = 0.904) after index surgery. Intraoperative tendency of oozing (visual analog scale: 35.8 vs 19.3; p = 0.011), adhesions (visual analog scale: 61.3 vs 46.2; p = 0.034), leak of colonic anastomosis (19% vs 0%; p = 0.012), leak of colonic or ileal anastomosis (24% vs 0%; p = 0.002), and reintervention (16% vs 0%; p = 0.026) were significantly higher after early closure. The concept of early closure failed in 10 patients (27% vs 0% in the late closure group (95% CI for the difference, 9.4%-44.4%)). LIMITATIONS: The trial was prematurely stopped because of safety issues. The aimed group size was not reached. CONCLUSIONS: Early stoma closure does not provide better quality of life up to 4 months after low anterior resection but is afflicted with significantly adverse feasibility and higher morbidity when compared with late closure.

Hubo datos de referencia comparables entre los grupos. No se produjeron diferencias en la calidad de vida 6 semanas (índice de calidad de vida gastrointestinal, media 99,8 vs. 106; p = 0,139) y 4 meses (108,6 vs 107,1, p = 0,904) después de la cirugía inicial. Tendencia intraoperatoria de supuración (escala analógica visual 35,8 vs 19,3, p = 0,011), adherencias (escala analógica visual 61,3 vs 46,2, p = 0,034), fuga de anastomosis colónica (19% vs 0%, p = 0,012), fuga de anastomosis colónica o ileal (24% vs 0%, p = 0,002) y reintervención (16% vs 0%, p = 0,026) fueron significativamente mayores después del cierre temprano. El concepto de cierre temprano fracasó en 10 pacientes (27% vs ninguno en el grupo de cierre tardío (intervalo de confianza del 95% para la diferencia: 9,4% a 44,4%)).LIMITACIONES:El estudio se detuvo prematuramente debido a problemas de seguridad. No se alcanzó el tamaño del grupo previsto.CONCLUSIÓN:El cierre temprano del estoma no proporciona una mejor calidad de vida hasta 4 meses posterior a una resección anterior baja, esto se ve afectado por efectos adversos significativos durante su realización y una mayor morbilidad en comparación con el cierre tardío.

Diagnosing developmental dysplasia of the hip using the Graf ultrasound method: risk and protective factor analysis in 11,820 universally screened newborns.

The essential role of ultrasound examinations in diagnosis and treatment of developmental dysplasia of the hip (DDH) is widely accepted while the weighting and correlation of protective factors and perinatal risk for DDH still give rise to debate. Our aim was to investigate the impact of single and twofold combined risk and protective factors on the newborns' hip maturity, assessed with the Graf ultrasound method. Therefore, data sets of 11,820 universally screened newborns were analyzed. Univariate and logistic regression analyses were performed to correlate risk and protective factors with mature or immature but appropriate for age and pathologic hip types. Thereby, female gender (OR 4.07 (95% CI 3.01-5.51), p < 0.001), breech presentation (4.98 (3.71-6.71), p < 0.001), and positive family anamnesis (5.05 (3.49-7.31), p < 0.001) as well as the combination of female gender with high birth weight (3.51 (2.45-5.03), p < 0.001) could be identified as independent predictive risk factors. Only low birth weight (0.27 (0.11-0.66), p = 0.004) could be identified as a single protective factor, while no combination of protective factors was significant. CONCLUSION: The significance and the informative value of risk and protective factor combinations, e.g., for selective ultrasound surveys, are limited. Early universal ultrasound screening using the Graf method is advised to timely detect hip immaturity and pathologies and to provide the optimal approach for mature or immature but appropriate for age and pathologic hips. What is Known: • Ultrasound screening is essential for diagnosis and treatment of DDH in time while the weighting and correlation of protective factors and perinatal risk and their role for the ultrasound screening protocol still give rise to debate. What is New: • The effects of single risk and protective factors for DDH do not cumulate or counteract, resulting in a limited value of a selective screening protocol based on risk and protective factors. • A universal screening protocol using the Graf ultrasound method is recommended.

Adductor Canal Compression Syndrome in a 46-Year-Old Female Patient Leading to Acute External Iliac, Femoral, and Popliteal Artery Thrombosis and Critical Ischemia: A Case Report.

The adductor canal compression syndrome is one of the several rare nontraumatic causes of arterial occlusions, which may lead to critical ischemia of the lower limb. We report the case of a 46-year-old athletic woman, who suffered from activity-related paresthesia and sharp pain in the left upper and lower leg for 2 years. Imaging and neurological investigations of the spine remained without pathological findings that would explain the patient's complaints. Actually, the patient presented with symptoms of critical lower limb ischemia. Magnetic resonance angiography revealed nearly complete thrombotic occlusion of the common femoral artery and the arteries of the lower leg. An emergency surgery was performed, revealing an external compression of the superficial femoral artery in the adductor canal. Subsequently, a thrombectomy was performed and a venous bypass graft was installed. No postoperative complications occurred, the patient recovered well and could return to her activities of daily living about 3 weeks after the surgery. The adductor canal compression syndrome results from a local anomalous musculotendinous band or hypertrophic musculature surrounding the passing structures. It mainly occurs in athletes exposed to repetitive stress, especially runners and skiers, and may lead to thrombosis followed by critical lower extremity ischemia. The lack of obvious symptoms during routine physical examination often impedes rapid diagnosis and timely therapy. Considering the high thrombotic risk, attention should be paid to this rare cause of lower limb pain to prevent the patient from critical lower extremity ischemia and potential limb loss due to consecutive acute thrombotic occlusions.

Enlargement of umbilical incision in standard laparoscopic cholecystectomy is frequently necessary: An argument for the single incision approach?

OBJECTIVE: Cosmetic result after cholecystectomy is up for debate. The aim of this study was to investigate the incidence and extent of enlargement of initial skin and fascia incision in standard laparoscopic cholecystectomy and to detect predictive factors for such an enlargement. MATERIAL AND METHODS: The size of the umbilical incision was measured before and after standard laparoscopic gallbladder removal in 391 patients from August 2009 to October 2012. Predisposing factors for the need of enlargement of the umbilical incision were analysed. RESULTS: Additional enlargement of the umbilical incision for gallbladder removal was required in 35.8% of the patients at skin level, and in 40.4% at fascia level. The median enlargement of the umbilical skin incision was 11 mm, from 25 mm to 36 mm. Gallbladder weight, total stone weight, maximum diameter of largest stone and shorter initial length of incision were independent predisposing factors for enlargement of the incision. CONCLUSIONS: In standard laparoscopic cholecystectomy the umbilical incision frequently requires secondary enlargement, especially if a large stone mass is involved. Therefore, the cosmetic result after laparoscopic cholecystectomy depends on more than only the technique used for access and the surgical technique for cholecystectomy should be chosen individually for each patient according to the stone mass.

Transanal endoscopic microsurgery (TEM) facilitated by video-assistance and anal insertion of a single-incision laparoscopic surgery (SILS(®))-port: preliminary experience.

OBJECTIVE: Transanal endoscopic microsurgery (TEM) is an established method for the resection of benign and early malignant rectal lesions. Very recently, TEM via an anally inserted single incision laparoscopic surgery (SILS(®))-port has been proposed to overcome remaining obstacles of the classical TEM equipment. METHODS: Nine patients with a total of 12 benign or early stage malignant rectal polyps were operated using the SILS(®)-port for TEM. Patients' and polyps' characteristics, perioperative and postoperative complications, as well as operating and hospitalization time were recorded. RESULTS: All 12 polyps (ten low-grade adenoma, one high-grade adenoma, one pT2 carcinoma [preoperatively staged as T1]) were resected. Local full-thickness bowel wall resection was performed for three lesions and submucosal resection for nine lesions. Median operating time was 64 (range 30-180) min. No conversion to laparoscopic or open techniques was necessary. The median maximum diameter of the specimen was 25 (range 3-60) mm, fragmentation of polyps was avoidable in 11 of 12 (92 %) lesions, and resection margins were histologically clear in 11 of 12 (92 %) polyps. Only one patient, in whom three lesions were resected, experienced a complication as postoperative hemorrhage. No mortality occurred. Median hospitalization time was four (range 1-14) days. CONCLUSIONS: SILS(®)-TEM is a feasible and safe method, providing numerous advantages in application, handling, and economy compared with the classical TEM technique. SILS(®)-TEM might become a promising alternative to classical TEM. Randomized, controlled trials comparing safety and efficacy of both instrumental settings will be needed in the future.

Intraoperative esophageal washout reduces free intraluminal tumor cells during resection of carcinomas of the esophagus and cardia.

OBJECTIVE: Intraluminally shed viable tumor cells might contribute to anastomotic recurrence in cancer of the esophagus and the cardia. The study aimed to establish a method of esophageal washout and, hence, to reduce intraluminal cancer cells before esophageal anastomosis. METHODS: Forty-eight consecutive patients with esophago-gastric resection for histologically proven cancer of the esophagus or the cardia were included in a prospective, interventional study. Before transection, the esophagus was clamped proximally to the tumor and rinsed with 1:10 diluted povidone-iodine-solution (10 × 30 ml) applied by a transorally inserted 24F-Foley catheter. The first, fifth and tenth portion of the lavage fluid were sent to cytological examination. RESULTS: Intraoperative frozen sections confirmed clear proximal resection margins of the esophagus. The cytological examination of the fluid recovered from the esophageal washout revealed malignant cells in 13/48 patients (27%). The presence of malignant cells was significantly less likely in patients with neoadjuvant treatment than in patients without neoadjuvant treatment: 2/23 (9%) vs. 11/25 (44%) (p = 0.009). Repetitive washout reduced the probability of detectable malignant cells from 13 to 8 (62%) patients after 5, and further to 4 patients (30%) after 10 washout maneuvers. CONCLUSIONS: Free malignant cells may be present in the esophageal lumen following intraoperative manipulation of cancers of the esophagus or cardia. Transoral washout of the esophagus is novel, feasible and enables reduction or even elimination of these tumor cells. The reliability of this procedure raises with increasing washout volume. Esophageal washout might be especially worthwhile in patients who do not receive neoadjuvant therapy.

Exploring the Effects of Local Air Pollution on Popliteal Artery Aneurysms.

Objectives: A growing body of evidence highlights the effects of air pollution on chronic and acute cardiovascular diseases, such as associations between PM10 and several cardiovascular events. However, evidence of the impact of fine air pollutants on the development and progression of peripheral arterial aneurysms is not available. Methods: Data were obtained from the multicenter PAA outcome registry POPART and the German Environment Agency. Means of the mean daily concentration of PM10, PM2.5, NO2, and O3 concentrations were calculated for 2, 10, and 3650 days prior to surgery for each patient. Additionally, weighted ten-year averages were analyzed. Correlation was assessed by calculating Pearson correlation coefficients, and regression analyses were conducted as multiple linear or multiple logistic regression, depending on the dependent variable. Results: For 1193 patients from the POPART registry, paired air pollution data were available. Most patients were male (95.6%) and received open surgical repair (89.9%). On a regional level, the arithmetic means of the daily means of PM10 between 2000 and 2022 were neither associated with average diameters nor runoff vessels. Negative correlations for mean PAA diameter and mean NO2, as well as a positive correlation with mean O3, were found; however, they were not statistically significant. On patient level, no evidence for an association of mean PM10 exposure over ten years prior to inclusion in the registry and PAA diameter or the number of runoff vessels was found. Weighted PM10, NO2, and O3 exposure over ten years also did not result in significant associations with aneurysm diameter or runoff vessels. Short-term air pollutant concentrations were not associated with symptomatic PAAs or with perioperative complications. Conclusions: We found no indication that long-term air pollutant concentrations are associated with PAA size or severity, neither on a regional nor individual level. Additionally, short-term air pollution showed no association with clinical presentation or treatment outcomes.

Deciphering Popliteal Artery Aneurysm Patient Diversity: Insights From a Cluster Analysis of the POPART Registry.

BACKGROUND: Popliteal artery aneurysms (PAAs) are the most common peripheral aneurysm. However, due to its rarity, the cumulative body of evidence regarding patient patterns, treatment strategies, and perioperative outcomes is limited. This analysis aims to investigate distinct phenotypical patient profiles and associated treatment and outcomes in patients with a PAA by performing an unsupervised clustering analysis of the POPART (Practice of Popliteal Artery Aneurysm Repair and Therapy) registry. METHODS AND RESULTS: A cluster analysis (using k-means clustering) was performed on data obtained from the multicenter POPART registry (42 centers from Germany and Luxembourg). Sensitivity analyses were conducted to explore validity and stability. Using 2 clusters, patients were primarily separated by the absence or presence of clinical symptoms. Within the cluster of symptomatic patients, the main difference between patients with acute limb ischemia presentation and nonemergency symptomatic patients was PAA diameter. When using 6 clusters, patients were primarily grouped by comorbidities, with patients with acute limb ischemia forming a separate cluster. Despite markedly different risk profiles, perioperative complication rates appeared to be positively associated with the proportion of emergency patients. However, clusters with a higher proportion of patients having any symptoms before treatment experienced a lower rate of perioperative complications. CONCLUSIONS: The conducted analyses revealed both an insight to the public health reality of PAA care as well as patients with PAA at elevated risk for adverse outcomes. This analysis suggests that the preoperative clinic is a far more crucial adjunct to the patient's preoperative risk assessment than the patient's epidemiological profile by itself.

Mesenteric ischemia-reperfusion injury: clearly improved hemodynamics but only minor protection of the rat small intestine by (sub)therapeutic heparin sodium and enoxaparin doses.

BACKGROUND: Tissue protection against ischemia (I)/reperfusion (R) injury by heparins can be due to their anticoagulant and/or non-anticoagulant properties. Here we studied the protective potential of the anticoagulant and the non-anticoagulant features of heparin sodium (HepSo) and enoxaparin (Enox) against mesenteric I/R injury in a rat model. MATERIALS AND METHODS: Mesenteric I/R was induced in rats (n = 6 per group) by superior mesenteric artery occlusion (SMAO; 90 min) and reopening (120 min). Therapeutic/clinical and subtherapeutic/non-anticoagulant doses of HepSo (0.25 mg/kg bolus + 0.25 mg/kg × h; 0.05 mg/kg bolus + 0.1 mg/kg × h) or Enox (0.5 mg/kg bolus + 0.5 mg/kg × h; 0.05 mg/kg bolus + 0.1 mg/kg × h) were administered intravenously starting 30 min before SMAO to the end of reperfusion. Systemic/vital and intestinal microcirculatory parameters were measured during the whole experimental procedure, those of small intestine injury at the end. RESULTS: During intestinal reperfusion, mean arterial blood pressure and heart rates were significantly increased by HepSo and, less effectively, by Enox, in a dose-dependent manner. Intestinal microcirculation was only affected by the therapeutic HepSo dose, which decreased the microvascular flow and S(O2) during reperfusion. The subtherapeutic Enox treatment, as opposed to any HepSo dose, most effectively diminished I/R-induced intestinal hemorrhages, myeloperoxidase activity (as a measure of neutrophil invasion), and histopathological changes. CONCLUSION: Therapeutic but, to a lesser extent, also the subtherapeutic doses of both HepSo and Enox clearly improve hemodynamics during mesenteric reperfusion, while intestinal protection is exclusively provided by Enox, especially at its subtherapeutic dose. Alterations in intestinal microcirculation are not responsible for these effects. Thus, non-anticoagulant Enox doses and, preferably, heparin(oid)s unable to affect coagulation, could diminish clinical risks of I/R-induced gastrointestinal complications.

Atypical and rare cause of myocardial infarction: coronary subclavian steal syndrome (CSSS) treated by a carotid-subclavian bypass in a 71-year-old female patient.

BACKGROUND: The coronary subclavian steal syndrome (CSSS) is a rare complication after coronary arterial bypass graft operations (CABG) using the left or right internal mammary artery ((L/R)IMA). It results from a retrograde blood flow from the IMA into the subclavian artery (SA) due to a stenosis or occlusion of the SA proximal to the IMA origin. This "steal phenomenon" leads to a decreased blood flow in the IMA and may result in myocardial ischemia (MIS) and even myocardial infarction (MIN). Treatment options include interventional and surgical therapy. CASE PRESENTATION: We report the case of a 71-year old woman, who suffered from an acute non-ST elevation myocardial infarction (NSTEMI) 11 years after LIMA-CABG surgery and who was treated successfully with a carotid-subclavian bypass (CSB) after failed interventional therapy. CONCLUSION: CSB may be regarded as a viable treatment option for patients suffering CSSS in the case of MIS and even an acute MIN/NSTEMI, especially in the case of missing or failed interventional therapy attempts. Specialists in cardiothoracic and vascular surgery should be aware of possible CSSS conditions and know about appropriate diagnostic and therapeutic options.

Symptomatic giant peritoneal loose body in the pelvic cavity: A case report.

INTRODUCTION: Giant peritoneal loose bodies (gPLB) occur rarely and therefore only few have been described. Often they are found incidentally and have no clinical relevance, whereas symptomatic forms may require surgical removal. PRESENTATION OF CASE: We report the case of a male patient suffering from abdominal discomfort with alternating localizations for several years, actually presenting with a proctitis. With elevated inflammatory markers, a conspicuous resistance in the lower abdomen and in order to evaluate further affection of the colon, an abdominal CT-scan was performed. It revealed a spherical mass in the lesser pelvis. A colonoscopy confirmed the proctitis, showing no further pathologies. Due to the symptoms and the uncertain entity of the mass, a diagnostic laparoscopy was performed and a boiled egg-like structure (diameter 5.2cm) was removed. The patient recovered well and was free of symptoms. DISCUSSION: The patient had two potential reasons for his symptoms, one of them being a suspected leftover foreign body years after an appendectomy. The proctitis was treated conservatively but without complete remission of the abdominal discomfort. Therefore, a diagnostic laparoscopy was performed and the mass turned out to be a gPLB. CONCLUSION: To obtain a fast diagnosis and to perform an adequate conservative or surgical therapy, the knowledge about the rare entity of a gPLB is necessary. An exact anamnesis, clinical examination and the knowledge about the diagnostic values of radiological and endoscopic investigations are crucial.

Liver resections can be performed safely without Pringle maneuver: A prospective study.

AIM: To evaluate liver resections without Pringle maneuver, i.e., clamping of the portal triad. METHODS: Between 9/2002 and 7/2013, 175 consecutive liver resections (n = 101 major anatomical and n = 74 large atypical > 5 cm) without Pringle maneuver were performed in 127 patients (143 surgeries). Accompanying, 37 wedge resections (specimens < 5 cm) and 43 radiofrequency ablations were performed. Preoperative volumetric calculation of the liver remnant preceeded all anatomical resections. The liver parenchyma was dissected by water-jet. The median central venous pressure was 4 mmHg (range: 5-14). Data was collected prospectively. RESULTS: The median age of patients was 60 years (range: 16-85). Preoperative chemotherapy was used in 70 cases (49.0%). Liver cirrhosis was present in 6.3%, and liver steatosis of ≥ 10% in 28.0%. Blood loss was median 400 mL (range 50-5000 mL). Perioperative blood transfusions were given in 22/143 procedures (15%). The median weight of anatomically resected liver specimens was 525 g (range: 51-1850 g). One patient died postoperatively. Biliary leakages (n = 5) were treated conservatively. Temporary liver failure occurred in two patients. CONCLUSION: Major liver resections without Pringle maneuver are feasible and safe. The avoidance of liver inflow clamping might reduce liver damage and failure, and shorten the hospital stay.

Long-term therapy of a patient with summerskill-walshe-tygstrup syndrome by applying prometheus® liver dialysis: a case report.

Summerskill-Walshe-Tygstrup syndrome is a rare benign chronic liver disease characterized by recurring cholestasis with jaundice and severe pruritus. Due to insufficient conservative treatment, liver dialysis by Prometheus(®) was applied to a 45-year-old female patient with resistant pruritus. Initially, other possible liver diseases were excluded and the patient was treated symptomatically since the diagnosis of Summerskill-Walshe-Tygstrup was stated in 1998. As conservative and endoscopic methods progressively failed to relieve the patient's suffering, Prometheus(®) liver dialysis was performed regularly since 2006 at 3-month intervals and successfully led to a decrease in the patient's symptoms. Cholestatic liver enzymes and also serum bile acids could be lowered significantly from an average of 22.5 ± 2.7 to 7.3 ± 1.7 µmol/l. Consequently, Prometheus(®) liver dialysis may be a beneficial option for patients with benign recurrent intrahepatic cholestasis suffering from therapy-resistant symptoms and may be used as well as other extracorporeal liver support devices which have already been reported to improve cholestatic pruritus.
