RESUMO
BACKGROUND: Differential diagnosis between benign uterine smooth muscle tumors and malignant counterpart is challenging. We evaluated the accuracy of a clinical and ultrasound based algorithm in predicting mesenchimal uterine malignancies (MUMs), including smooth muscle tumors of uncertain malignant potential (STUMPs). METHODS: We report the twelve-months follow-up of an observational, prospective, single-centre study that included women with at least one myometrial lesion ≥3 cm on ultrasound examination. These patients were classified according to a three-class diagnostic algorithm, using symptoms and ultrasound features. "White" patients underwent annual telephone follow-up for 2 years, "Green" patients underwent a clinical and ultrasound follow-up at 6, 12 and 24 months and "Orange" patients underwent surgery. We further developed a risk class system to stratify the malignancy risk. FINDINGS: 2,268 women were included andtarget lesion was classified as benign in 2,158 (95.1%), as other malignancies in 58 (2.6%) an as mesenchymal uterine malignancies in 52 (2.3%) patients. At multivariable analysis, age (OR 1.05 (95% CI 1.03-1.07), tumor diameter >8 cm (OR 5.92 (95% CI 2.87-12.24), irregular margins (OR 2.34 (95% CI 1.09-4.98), color score=4 (OR 2.73 (95% CI 1.28-5.82), were identified as independent risk factors for malignancies, whereas acoustic shadow resulted in an independent protective factor (OR 0.39 (95% CI 0.19-0.82). The model, which included age as a continuous variable and lesion diameter as a dichotomized variable (cut-off 81 mm), provided the best AUC (0.87 (95% CI 0.82-0.91)). A risk class system was developed, and patients were classified as low-risk (predictive model value <0.39%: 0/606 malignancies, risk 0%), intermediate risk (predictive model value 0.40%-2.2%: 9/1,093 malignancies, risk 0.8%), high risk (predictive model value ≥2.3%: 43/566 malignancies, risk 7.6%). CONCLUSION: The preoperative three-class diagnostic algorithm and risk class system can stratify women according to risk of malignancy. Our findings, if confirmed in a multicentre study, will permit differentiation between benign and MUMs allowing a personalized clinical approach. FUNDING: Nothing to declare.
RESUMO
BACKGROUND: The significance of reinforcement of the duodenal stump with seromuscular sutures and the effectiveness of reinforced staplers in preventing duodenal stump leakage remain unclear. We aimed to explore the importance of duodenal stump reinforcement and determine the optimal reinforcement method for preventing duodenal stump leakage. METHODS: This retrospective cohort study was conducted between January 1, 2012 and December 31, 2021, with data analyzed between December 1, 2022 and September 30, 2023. This multicenter study across 57 institutes in Japan included 16,475 patients with gastric cancer who underwent radical gastrectomies. Elective open or minimally invasive (laparoscopic or robotic) gastrectomy was performed in patients with gastric cancer. RESULTS: Duodenal stump leakage occurred in 153 (0.93%) of 16,475 patients. The proportions of males, patients aged ≥ 75 years, and ≥ pN1 were higher in patients with duodenal stump leakage than in those without duodenal stump leakage. The incidence of duodenal stump leakage was significantly lower in the group treated with reinforcement by seromuscular sutures or using reinforced stapler than in the group without reinforcement (0.72% vs. 1.19%, p = 0.002). Duodenal stump leakage incidence was also significantly lower in high-volume institutions than in low-volume institutions (0.70% vs. 1.65%, p = 0.047). The rate of duodenal stump leakage-related mortality was 7.8% (12/153). In the multivariate analysis, preoperative asthma and duodenal invasion were identified as independent preoperative risk factors for duodenal stump leakage-related mortality. CONCLUSIONS: The duodenal stump should be reinforced to prevent duodenal stump leakage after radical gastrectomy in patients with gastric cancer.
RESUMO
PURPOSE: Polymeric clips (Hem-o-lok ligation system) are now widely used to securing the base of the appendix during laparoscopic appendectomy. Studies comparing the use of single or double hem-o-lok clips are limited. The aim of this study was to compare the reliability of a single hem-o-lok clips with a double hem-o-lok clips for closure of an appendiceal stump. METHODS: This prospective randomized study includes patients from two centers who underwent laparoscopic appendectomy with the diagnosis of appendicitis between September 2020 and March 2023. Demographic, operative and clinical outcomes of the use of single or double hem-o-lok clips for closure of the appendiceal stump were compared. Factors affecting long postoperative hospital stay were investigated using univariate and multivariate analyzes. RESULTS: One hundred forty two (48.3%) patients in the single hem-o-lok arm and 152 (51.7%) patients in the double hem-o-lok arm were included in the analysis.The shortest operative time was noted in the single hem-o-lok group (52.1 ± 19.9 versus 61.6 ± 24.9 min, p < 0.001). The median hospital stay was 1 day (range 1-10) in the single hem-o-lok group and 1 day (range 1-12) in the double hem-o-lok group, and was shorter in the single hem-o-lok arm (1.61 ± 1.56 vs 1.84 ± 1.69, p = 0.019). Based on multivariate analysis, drain placement was identified as an independent predictive factor for long hospital stay. CONCLUSIONS: The use of single hem-o-lok clips for appendiceal stump closure during laparoscopic appendectomy is safe and effective. Trial registration NCT04387370 ( http://www. CLINICALTRIALS: gov ).

OBJECTIVE: This study introduced the modified Q-type purse-string suture duodenal stump embedding method, a convenient way to strengthen the duodenum, and compared it to the conventional one to assess its efficacy and safety. METHODS: This retrospective analysis examined 612 patients who received laparoscopic gastrectomy for gastric Cancer at a single center. The patients were divided into Not Reinforced Group (n = 205) and Reinforced Group (n = 407) according to the surgical approach to the duodenal stump. The reinforced group was further divided into a modified Q-type purse-string suture embedding method group (QM, n = 232) and a conventional suture duodenal stump embedding method group (CM, n = 175) according to the methods of duodenal stump enhancement. Clinicopathological characteristics, operative variables, and short-term complications were documented and analyzed. RESULTS: The incidence of duodenal stump leakage(DSL) in the Not Reinforced Group was higher compared to the Reinforced Group, although the difference was not statistically significant [2.4% (5/205) vs 0.7% (3/407), p = 0.339]. Additionally, the Not Reinforced Group exhibited a higher rate of Reoperation due to DSL compared to the Reinforced Group [2 (1.0%) vs. 0, p = 0.046], with one patient in the Not Reinforced Group experiencing mortality due to DSL [1 (0.5%) vs 0, p = 0.158]. Subgroup analysis within the Reinforced Group revealed that the modified Q-type purse-string suture embedding group (QM) subgroup demonstrated statistically significant advantages over the conventional suture embedding group (CM) subgroup. QM exhibited shorter purse-string closure times (4.11 ± 1.840 vs. 6.05 ± 1.577, p = 0.001), higher purse-string closure success rates (93.1% vs. 77.7%, p = 0.001), and greater satisfaction with purse-string closure [224 (96.6%) vs 157 (89.7%), p = 0.005]. No occurrences of duodenal stump leakage were observed in the QM subgroup, while the CM subgroup experienced two cases [2 (1.1%)], though the difference was not statistically significant. Both groups did not exhibit statistically significant differences in secondary surgery or mortality related to duodenal stump leakage. CONCLUSION: Duodenal Stump Leakage (DSL) is a severe but low-incidence complication. There is no statistically significant relationship between the reinforcement of the duodenal stump and the incidence of DSL. However, laparoscopic reinforcement of the duodenal stump can reduce the severity of fistulas and the probability of Reoperation. The laparoscopic Q-type purse-string suture duodenal stump embedding method is a simple and effective technique that can, to some extent, shorten the operation time and enhance satisfaction with purse-string closure. There is a trend towards reducing the incidence of DSL, thereby improving patient prognosis to a certain extent.

HYPOTHESIS: This study aimed to investigate the correlation between rotator cuff stump classification and postoperative outcomes after superior capsular reconstruction (SCR). METHODS: A total of 75 patients who underwent SCR between June 2013 and May 2021 were included in this study. Based on stump classification using the signal intensity ratio of the tendon rupture site to the deltoid muscle in the coronal view of preoperative T2-weighted, fat-suppressed magnetic resonance imaging scans, the patients were classified into types 1, 2, and 3 with ratios of <0.8, 0.8-1.3, and >1.3 (44, 17, and 14 patients, respectively). The American Shoulder and Elbow Surgeons (ASES), Constant, and visual analog scale (VAS) scores for pain and range of motion were evaluated at a minimum of 1 year of follow-up postoperatively. The acromiohumeral distance and rotator cuff arthropathy according to the Hamada classification were assessed on plain radiography. The graft integrity was evaluated by magnetic resonance imaging at 3 and 12 months postoperatively and annually thereafter. RESULTS: Clinical and radiological outcomes were significantly improved after SCR. In comparison with type 2 and 3 patients, type 1 patients had significantly higher ASES scores (type 1, 2, and 3 = 84 ± 10, 75 ± 15, and 76 ± 14; all P = .014), Constant scores (type 1, 2, and 3 = 65 ± 5, 61 ± 9, and 56 ± 13; all P = .005), and forward flexion (type 1, 2, and 3 = 155 ± 10, 154 ± 15, and 145 ± 13; all P = .013). However, these statistical differences between groups were below the established minimum clinically important difference values for the ASES and Constant scores after rotator cuff repair. The graft failure rate after surgery was lower in the type 1 group than that in the other 2 groups; however, the difference was not statistically significant (P = .749). CONCLUSION: Patients with stump classification type 1 showed significantly better functional scores (ASES and VAS scores) and forward flexion; however, the clinical importance of these differences may be limited. Stump classification may be useful for predicting postoperative clinical outcomes.

PURPOSES: Closure of the appendix stump is necessary for laparoscopic appendectomy. Problems that occur during the appendix stump closure can cause severe morbidity. Several methods of stump closure have been described. This study aimed to investigate the adequacy of LigaSure alone in closing the appendix stump. METHODS: Patients who were operated on with the diagnosis of acute appendicitis between October 2021 and January 2022 were evaluated retrospectively. The patients were divided into two groups according to the closure technique of the appendix stump hemoclip(group I) and LigaSure only(group II). In addition, demographic data (age, gender), body mass index (BMI), presence of comorbid disease, perioperative appendicitis classification, operation time, postoperative hospital stay, radiological and pathological appendix size of the patients included in the study were recorded. Clavien Dindo was used for postoperative complication assessment. RESULT: The study included 77 patients. 48(62.3%) of the patients were in group I, and 29(37.7%) were in group II. There was no statistical difference between the groups regarding age, gender distribution, BMI, presence of comorbid disease (P > .05). The operation time of group I was longer than group II (P < .001). There was no difference between the groups in terms of both radiological and pathological appendix size. There was no statistical difference between the groups regarding postoperative complications and severity of complications (P = .76, P = .99, respectively). CONCLUSION: Appendiceal stump closure can be performed with Ligasure, but it should be noted that this procedure can be performed on selected patients, as in the study group, not on all patients.

INTRODUCTION: Stump syndrome is defined as a clinical syndrome resulting from a distal intracranial vessel embolic stroke due to an extracranial vessel occlusion. Similar to the anterior circulation, the recurrence of ischemic strokes in territories supplied by the posterior circulation in the presence of vertebral artery occlusion is termed Vertebral Artery Stump Syndrome (VASS). MATERIAL AND METHODS: We conducted a literature review, identifying 72 patients with transient ischemic attacks (TIAs) or ischemic strokes attributed to VASS, according to Kawano criteria. We categorized all patients in two groups focusing on the therapeutic management those who underwent primary medical treatment and those who received endovascular or surgical treatment either in acute or chronic phase. RESULTS: In the anticoagulant therapy group, only 1 patient had a stroke recurrence. Among the 4 on antiplatelets, all had recurrences, but 3 benefited from switching to anticoagulants or endovascular therapy. In the endovascular therapy group, worse outcomes were linked to acute large vessel occlusion. Endovascular treatment of the vertebral artery, in a chronic phase, was explored in literature for recurrent TIAs or minor strokes suggesting that this could be a viable therapeutic alternative when medical treatment failed in preventing recurrence of ischemic stroke. CONCLUSIONS: Some studies suggest that anticoagulant medical therapy may be beneficial for VASS and endovascular therapy has also been reported for selected patients. However, data on treatment outcomes and prognosis are still underreported, making treatment decisions challenging. Randomized Controlled Trials are needed to establish the optimal treatment approach.

Lung resection surgery, which is performed as a treatment for lung cancer and metastatic lung tumors, is currently conducted via minimally invasive techniques such as video-assisted thoracoscopic surgery and robot-assisted methods. Postoperative complications related to this surgery, such as pulmonary vein thrombosis and cerebral and other organ infarctions, have been increasingly reported. The primary cause of these complications is thrombus formation in the pulmonary vein stump. Statistical data on the site of lung lobectomy have indicated that surgeries involving the left upper lobe are most frequently associated with embolic complications. Although this issue has not received considerable attention in anesthesiology, the importance of prevention and treatment in postoperative management is growing. The role of anesthesiologists in preventing these complications is critical. These roles involve careful fluid management to avoid hypercoagulable states, consideration of early postoperative anticoagulation therapy, assessment of the suitability of epidural anesthesia for postoperative anticoagulation, and improvement of hospital-wide safety systems and monitoring of high-risk patients. Anesthesiologists need to understand the pathology and risk factors involved and play an active role in preventing and treating these complications through effective collaboration with thoracic surgeons and the in-hospital stroke team.
RESUMO
OBJECTIVE: To demonstrate the capabilities and advantages of double-tract reconstruction after gastrectomy for gastric cancer and simultaneous approach in surgical treatment of patients with cardiovascular diseases and gastric cancer. MATERIAL AND METHODS: We present two cases of double-tract reconstruction after gastrectomy and the gastric stump extirpation as a part of simultaneous surgical approach to patients with gastric cancer and cardiovascular diseases. A 62-year-old patient underwent simultaneous gastrectomy with double-tract reconstruction (for the first time In Russia) and aortofemoral replacement. A 61-year-old patient underwent simultaneous coronary artery bypass surgery, gastric stump extirpation with esophagogastrostomy and double-tract reconstruction. RESULTS: In 1 case, postoperative period was complicated by subcompensated stenosis of the right ureter due to hematoma near the right common iliac artery. This event required endoscopic stenting of the right ureter with positive effect. Both patients were discharged in 16 and 23 days after surgery. CONCLUSION: This method may be alternative to modern reconstructions. Currently, digestive tract reconstruction after gastrectomy is still important and requires further study. Simultaneous procedures in patients with cancer and cardiovascular disease became more widespread. To objectify our statements, further research is needed.

Introduction: Leiomyosarcoma (LMS), together with smooth muscle tumors of uncertain malignant potential (STUMP) and benign leiomyomas, belongs to a heterogeneous group of uterine neoplasms. According to the World Health Organization, tumors originating from uterine smooth muscle fibers are the second most frequent tumors. It is challenging to distinguish between STUMP and LMS because of an overlap of symptoms, lack of a precise definition, and unequivocal information obtained using imaging diagnostic methods. Following myomectomy or hysterectomy with laparoscopic or laparotomy surgery and a definitive histological diagnosis of STUMP, the course of treatment is determined by the need to preserve fertility. In 2014, the U.S. Food and Drug Administration published an alert that unprotected laparoscopic morcellation is correlated with a 3-fold higher likelihood of dissemination of malignant cells and disease progression. Unprotected morcellation was independently associated with a higher risk of disease recurrence after demolition or conservative surgery, with a relative risk of 2.94. Conclusion: Hematoperitoneum resulting from the spontaneous rupture of a uterine tumor is a rare gynecological emergency, with very few cases reported in the last decade.
RESUMO
INTRODUCTION AND IMPORTANCE: Uterine smooth muscle tumor of uncertain malignant potential (STUMP) is rare tumor, and regarded as sub-classification in uterine smooth muscle tumors between benign and malignant criteria. They represent a heterogeneous group of rare tumors. PRESENTATION OF CASE: We report a case of a STUMP tumor in a fifty-three-year-old patient who underwent surgery for a hysterectomy. DISCUSSION: STUMP often presents with nonspecific clinical manifestation the only confirmatory examination is anatomopathological and may be supported by immunohistochemistry, hysterectomy is currently considered the gold standard of treatment. CONCLUSION: Uterine STUMP tumor represents a therapeutic dilemma. A multidisciplinary approach is mandatory.
RESUMO
Uterine smooth muscle tumors of undetermined malignant potential (STUMPs) are an uncommon kind of uterine smooth muscle tumor. It is distinguished by histopathologic and morphologic characteristics that are in between those of a benign leiomyoma and a malignant leiomyosarcoma. From a clinical standpoint, the clinical presentation of STUMP is similar to that of a fibroid. The diagnosis is usually confirmed after surgery. Here, we report the case of a 39-year-old woman who experienced increased menorrhagia, back pain, and pressure sensations during the past six months. She had a well-defined, freely movable lump in her lower abdomen, measuring the size of a 22-cm uterus. The patient exhibited pallor, and her imaging scan showed the presence of an intramural posterior uterine solid mass indistinguishable from fibroid measuring 8.5 × 9 cm. Goserelin acetate (Zoladex 3.6 mg implant) was recommended for a duration of six months. The patient experienced a significant amelioration in menorrhagia and discomfort. However, no reduction in the size of the mass was observed. Myomectomy was made for the suspicion of a malignant transformation. The histology examination confirmed the diagnosis of a STUMP; a hysterectomy was undergone, and the procedure went smoothly. The patient was discharged home in good condition with instructions for long-term follow-up due to a risk of recurrence of about 7%. The lack of standardized and clear clinical and diagnostic criteria for STUMP adds challenges to their management.
RESUMO
INTRODUCTION: Stump hyperhidrosis is a common condition after lower limb amputation. It affects the prosthesis use, and the quality of life of patients. Several case reports tried to prove benefit of using Botulinum toxin in its treatment. AIM: This study was to conduct a larger workforce clinical trial and to demonstrate benefits of botulinum toxin injection in the treatment of stump hyperhidrosis. METHODS: A prospective study was conducted. War amputees who complained of annoying excessive sweating of the stump were included. They received intradermal injection of botulinum toxin A in the residual limb area in contact with prosthetic socket. Abundance of sweating and degree of functional discomfort associated with it were assessed before, after 3 weeks, 6 and 12 months. RESULTS: Seventeen male patients, followed for post-traumatic limb amputation were included in the study. Discomfort and bothersome in relation to Hyperhidrosis did decrease after treatment (p<0,001). Reported satisfaction after 3 weeks was 73,33%. Improvement of prothesis loosening up after 3 weeks was 72,5% [±15,6]. Mean injection-induced pain on the visual analogue scale was 5.17/10 (±1.58). The mean interval after the onset of improvement was 5.13 days [min:3, max:8]. The mean time of improvement was 10.4 months after the injection [min:6, max:12]. No major adverse events were reported following treatment. CONCLUSION: Intradermal injections of botulinum toxin in the symptomatic treatment of stump hyperhidrosis are effective and have few adverse effects. It improves the quality of life of our patients thanks to a better tolerance of the prosthesis.

BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) is one of the most frequently performed procedures in sports medicine, and undesirable outcomes still may range from 3-18%. One technique that has been explored to improve outcomes is preservation of the ACL remnant tibial stump, as opposed to stump debridement, at the time of reconstruction. PURPOSE: To review current high-level evidence and compare remnant-preserving anterior cruciate ligament reconstruction (ACLR) versus standard ACLR in terms of clinical outcomes and measures of knee stability. HYPOTHESIS: ACLR with remnant preservation would result in improved clinical outcomes and knee stability measures. STUDY DESIGN: Systematic review; Level of evidence, 2. METHODS: A systematic review of randomized controlled trials (RCTs) and cohort studies comparing remnant-preserving ACLR with standard ACLR with a minimum level of evidence of 2 was performed. Extracted data were summarized as general information, surgical characteristics, postoperative clinical outcomes, knee stability, graft evaluation, tunnel assessment, and postoperative complications. When feasible, a meta-analysis was performed. RESULTS: Seven RCTs and 5 cohort studies met the inclusion criteria. In total, 518 patients underwent remnant-preserving ACLR and 604 patients underwent standard ACLR. Ten studies performed the reconstruction with hamstring tendon (HT) autografts, 1 study with HT and bone-patellar tendon-bone autografts, and 1 study with HT and tibialis anterior allografts. On meta-analysis, remnant-preserving ACLR provided comparable outcomes with respect to International Knee Documentation Committee grades or Tegner scores. Even though there was a significant improvement in Lysholm scores (mean difference, -1.9; 95% CI, -2.89 to -0.91; P = .0002) with the remnant-preserving technique, this did not exceed previously reported minimal clinically important difference values. Remnant-preserving ACLR demonstrated superior knee stability in terms of patients achieving negative pivot shift when compared with the control group (88.89% vs 79.92%; P = .006). Although there was a significant improvement in the side-to-side difference in anterior tibial translation favoring remnant preservation (P = .004), the mean difference was 0.51 mm. CONCLUSION: Remnant-preserving ACLR, primarily with HT autografts, results in comparable clinical outcome scores and significantly improved knee stability relative to standard ACLR without remnant preservation without increasing the complication rate. Further studies will help clarify if remnant-preserving ACLR also has benefits in terms of enhancing graft integration and maturation, improving proprioception, limiting tunnel enlargement, and reducing complications.
RESUMO
Introduction Acute appendicitis is a common cause of acute abdomen and the most frequent surgical emergency in the world. Since the nineteenth century, surgical resolution has been the most accepted treatment worldwide, and laparoscopic appendectomy is currently preferred as the treatment of choice because it has several benefits. The closure of the appendiceal stump is the most crucial step during appendectomy since its inadequate management can cause post-surgical complications. Throughout recent years, several methods have been proposed to perform this closure. This study was performed to compare the post-surgical outcomes of the use of endoloop and endostapler devices. Methods This is a retrospective study of 290 patients aged 18 to 83 who underwent laparoscopic appendectomy between 2016 and 2020. Demographic data, clinical history, tomographic findings, and laboratory data were collected, as well as appendicular base management technique, severity degree of appendicitis at hospital admission, postoperative complications at 30 days, hospital readmission, and in-hospital stay. Statistical tests and binary logistic regression analyses were used to identify risk factors, with a significance level of p<0.05. Results Demographic data and clinical history did not show statistically significant differences. The presence of a pre-surgical abscess with tomography was 1.58 times higher in the endostapler group. Post-surgical results showed that the use of endostapler devices represented a 2.7 times higher risk of post-surgical abscess. The endostapler group was also found to have 1.87 times the risk of post-surgical sepsis. Conclusion Our study shows that the use of an endoloop reduces the risk of postoperative abscess by 16.5% and protects against the development of post-surgical sepsis by 30%.
RESUMO
This study aimed to compare outcomes of hand-sewn and stapler closure techniques of pancreatic stump in patients undergoing distal pancreatectomy (DP). Impact of stapler closure reinforcement using mesh on outcomes was also evaluated. Literature search was carried out using multiple data sources to identify studies that compared hand-sewn and stapler closure techniques in management of pancreatic stump following DP. Odds ratio (OR) was determined for clinically relevant postoperative pancreatic fistula (POPF) via random-effects modelling. Subsequently, trial sequential analysis was performed. Thirty-two studies with a total of 4,022 patients undergoing DP with hand-sewn (n = 1,184) or stapler (n = 2,838) closure technique of pancreatic stump were analyzed. Hand-sewn closure significantly increased the risk of clinically relevant POPF compared to stapler closure (OR: 1.56, p = 0.02). When stapler closure was considered, staple line reinforcement significantly reduced formation of such POPF (OR: 0.54, p = 0.002). When only randomized controlled trials were considered, there was no significant difference in clinically relevant POPF between hand-sewn and stapler closure techniques (OR: 1.20, p = 0.64) or between reinforced and standard stapler closure techniques (OR: 0.50, p = 0.08). When observational studies were considered, hand-sewn closure was associated with a significantly higher rate of clinically relevant POPF compared to stapler closure (OR: 1.59, p = 0.03). Moreover, when stapler closure was considered, staple line reinforcement significantly reduced formation of such POPF (OR: 0.55, p = 0.02). Trial sequential analysis detected risk of type 2 error. In conclusion, reinforced stapler closure in DP may reduce risk of clinically relevant POPF compared to hand-sewn closure or stapler closure without reinforcement. Future randomized research is needed to provide stronger evidence.
RESUMO
Duodenal stump insufficiency is an infrequent but potentially devastating complication of upper gastrointestinal surgery. In the era of image-guided interventions, duodenal stump insufficiency is usually treated rather conservatively or with percutaneous interventions than with surgery. Herein, we present a case of a postsurgical duodenal stump fistula successfully treated in a step-by-step manner with percutaneous drainage of a periduodenal abscess-fistula complex, percutaneous transcholecystic biliary drainage for partial biliary diversion and percutaneous transcatheter fistula embolization via the duodenum with n-butyl-cyanoacrylate.
RESUMO
OBJECTIVE: The current Instructions for Use (IFU) of cyanoacrylate closure (CAC) is to start initial injection with the catheter tip positioned 5 cm distal to the sapheno-femoral junction (SFJ) to prevent endovenous glue-induced thrombosis (EGIT). However, this defensive design is responsible for the relatively long stump length. Although clinical studies on the long-term recurrence rate are still lacking, the long stump length can predict a higher long-term recurrence rate compared to other surgical methods. The author developed a novel surgical technique that can overcome the weakness of CAC, and the initial outcomes of this technique are described in this article. METHODS: This study retrospectively reviewed 25 great saphenous vein (GSV) in 20 patients who underwent CAC for incompetent GSV at our hospital. The procedure from puncturing the GSV to insertion of the catheter is the same as the conventional method. Place the catheter tip 2-3 cm below the SFJ before cyanoacrylate injection. After confirming the position of the SFJ with the longitudinal view of the ultrasound, press the GSV directly above the SFJ transversely with the second to fifth fingertips of the left hand. Then, the ultrasound probe is placed against the distal part of the fingertips, and CA injection is performed while GSV is monitored in real time. RESULTS: The mean stump length immediately after surgery was 19.3 (± 7.8) mm, with a range of .0-38.4 mm. The mean stump length after 1 week was 12.3 (± 7.4) mm and the range was .1-35.4 mm. The mean stump length after 1 month was 15.4 (± 10.1) mm, and the range was .0-35.4 mm. There was no case with EGIT or recanalization. CONCLUSIONS: The author confirmed the possibility of safely reducing stump length with this novel surgical technique, and expect that this method can help overcome the weakness of CAC.

Pituitary apoplexy (PA) is an emergency condition caused by sudden hemorrhage or infarction and characterized by sudden sella turcica compression, intracranial hypertension and meningeal stimulation. PA usually occurs secondary to pituitary adenomas and can serve as the initial manifestation of an undiagnosed pituitary adenoma in an individual. In the present study, a case of PA following surgery for cervical stump adenocarcinoma was reported. The patient experienced an abrupt onset of headache and drowsiness on postoperative day 1 (POD1), and developed blurred vision and blepharoptosis of the left eye on POD4. Pituitary MRI confirmed the diagnosis of PA, prompting the initial administration of hydrocortisone to supplement endogenous hormones, followed by trans-sphenoidal resection. At the six-week follow-up, the patient had fully recovered, with only mild residual blurring of vision. Diagnosing PA post-surgery can be a challenging task due to its symptomatic overlap with postoperative complications. The existing literature on PA after surgery was also reviewed, including the symptoms, time of onset, imageological examination, management, potential risk factors and outcome to improve on early detection and individualized treatment in the future.
RESUMO
The left atrial appendage (LAA) is now recognized as a significant contributor to arrhythmia and thromboembolism in patients with a history of atrial fibrillation. Thoracoscopic exclusion of the LAA is made possible with the AtriClip device. In this report, we describe the case of a 65-year-old man with history of multiple left atrial ablation procedures and LAA clipping. He developed a microreentrant atrial tachycardia originating from the anterior base of the LAA stump, underwent complete isolation of the LAA, and had subsequent resolution of arrhythmogenic activity from the residual LAA stump.
