BMC Gastroenterology May 2024To systematically analyze risk factors for delayed postpolypectomy bleeding (DPPB) in colorectum. (Meta-Analysis)
Meta-Analysis
BACKGROUND
To systematically analyze risk factors for delayed postpolypectomy bleeding (DPPB) in colorectum.
METHODS
We searched seven large databases from inception to July 2022 to identify studies that investigated risk factors for DPPB. The effect sizes were expressed by relative risk (RR) and 95% confidence interval (95% CI). The heterogeneity was analyzed by calculating I values and performing sensitivity analyses.
RESULTS
A total of 15 articles involving 24,074 subjects were included in the study. The incidence of DPPB was found to be 0.02% (95% CI, 0.01-0.03), with an I value of 98%. Our analysis revealed that male sex (RR = 1.64), history of hypertension (RR = 1.54), anticoagulation (RR = 4.04), polyp size (RR = 1.19), polyp size ≥ 10 mm (RR = 2.43), polyp size > 10 mm (RR = 3.83), polyps located in the right semicolon (RR = 2.48) and endoscopic mucosal resection (RR = 2.99) were risk factors for DPPB.
CONCLUSIONS
Male sex, hypertension, anticoagulation, polyp size, polyp size ≥ 10 mm, polyps located in the right semicolon, and endoscopic mucosal resection were the risk factors for DPPB. Based on our findings, we recommend that endoscopists should fully consider and implement effective intervention measures to minimize the risk of DPPB.

We discuss a patient with a tumor on the anterior corpus callosum who underwent open biopsy eventually succumbing to cerebrogenic fatal arrhythmia following wounded glioma syndrome. A healthy 37-year-old female patient was admitted to our department due to a history of headache for 13 months. MRI revealed a suspicious glioma infiltrating the anterior corpus callosum. Neurologic examination only showed low cognitive assessment score (Montreal Cognitive Assessment score 20/30). ECG was normal sinus rhythm. Steroids and levetiracetam were administered prior to operation. Patient underwent right frontal craniotomy and biopsy of tumor with unremarkable events. During the first hospital day, patient had episodes of bradycardia followed by decrease in sensorium. Brain CT scan showed progression of edema without hemorrhage within the tumor bed. This was followed minutes later by two episodes of generalized tonic-clonic seizures and pulseless ventricular tachycardia. Cardiac resuscitation was done for 24 minutes but patient eventually expired. Location of the lesion and the epileptogenicity of the peritumoral cortex greatly contributed to the patient's demise. Involvement of the fronto-mesial structures, particularly the insula and the cingulate cortex, and their connection to the central autonomic network, increased susceptibility to arrhythmias. Decreased seizure threshold worsened post-operative edema, further aggravating the dysregulation of the brain-heart-connection.

BACKGROUND
Intracranial meningiomas, being a fairly common disease in the population, often require surgical treatment, which, in turn, can completely heal the patient. The localization of meningiomas often influences treatment even if they are asymptomatic. By modernizing approaches to surgical treatment, it is possible to minimize intra- and postoperative risks, while achieving complete removal of the tumor. One of these methods is minimally invasive neurosurgery, the development of which in recent years allows it to compete with standard surgical methods. The purpose of this study was the objectification of minimally invasive approaches, such as the calculation of the craniotomy area and the ratio of craniotomy area to the resected tumor volume.
METHODS
The retrospective study consisted of a group of 54 consecutive patients who were operated on in our neurosurgery clinic specialized on minimally invasive neurosurgery. Preoperative planning was carried out using the Surgical Theater visualization platform. Using this system, the tumor volume and craniotomy surface area were calculated. During the analysis, the symptoms before and after the surgery, classification of tumors, postoperative complications, further treatment and follow-up results were assessed.
RESULTS
Twelve (22.2%) patients were men and 42 (77.8%) were women. The mean age of the group was 64.2 years (median 67.5). The craniotomy area ranged from 202 to 2,108 mm² (mean 631 mm²). Tumor volume ranged from 0.85 to 110.1 cm (mean 21.6 cm). The craniotomy size of minimally invasive approaches to the skull base was 3-5 times smaller than standard approaches. Skull base meningiomas accounted for 19 cases (35.2%), convexity meningiomas for 26 cases (48.1%), and falx and tentorium meningiomas for 9 cases (16.7%). Three complications were reported: postoperative hemorrhage, CSF leakage, and ophthalmoplegia. Relapse was detected in 2 patients with a mean follow-up of 26.3 months (median 20).
CONCLUSION
Minimally invasive approaches in the surgical treatment of intracranial meningiomas reduce the possibility of operating trauma by several times; they are safe and sufficient for complete removal of the tumor.

We report a case of delayed bleeding after video-assisted thoracic surgery (VATS) that was successfully treated with transcatheter arterial embolization. An 81-year-old woman underwent a pleural biopsy via VATS for pleural dissemination of lung cancer. The postoperative course was good, but 8 days later she was hospitalized for swelling in the right axilla and was admitted to our hospital with a diagnosis of delayed postoperative hemorrhage. Gauze compression was performed, and the patient was discharged without exacerbation of hematoma. However, 4 days later, she was hospitalized for rapidly worsening swelling and pain. Chest computed tomography at the time of rebleeding showed an increase in the hematoma and extravasation in the peripheral right lateral thoracic artery. The patient was immediately treated with emergency angiography, and coil embolization was performed. After this treatment, the patient has done well and there has been no subsequent recurrence of bleeding.

BACKGROUND
Ventriculoperitoneal (VP) shunt placement is one of the most performed procedures in neurosurgery to treat various types of hydrocephalus (HC). Immediate or late postoperative complications may quite commonly occur, especially in immunosuppressed patients, who are predisposed to develop rare and difficult-to-treat conditions.
CASE DESCRIPTION
Herein, we report the case of a 41-year-old female patient with a prior history of acute myeloid leukemia, followed by a tetra-ventricular acute HC due to a spontaneous non-aneurysmal subarachnoid hemorrhage. After an urgent external ventricular drainage placement, she underwent careful testing of "shunt dependency," which ended with a VP shunt placement. After 2 months, she presented at the emergency department with worsening abdominal pain and fever. She underwent a computed tomography scan with contrast administration, which has shown abscesses in the abdominal cavity. An urgent surgical revision of the VP shunt and antibiotics administration followed this. After inflammatory markers normalization, due to the high risk of post-infective peritoneal adherence and consequent impairment of cerebrospinal fluid absorption, a ventriculoatrial shunt was considered the most appropriate solution.
CONCLUSION
Abdominal abscesses are a rare but subtle complication after VP shunt placement. Their management depends on etiology, patient clinical characteristics, and manifestations. Prompt interventions have been shown to improve clinical outcomes and optimize quality of life in such delicate patients.

BACKGROUND
Bilateral vertebral artery dissection aneurysm (VADA) is a rare condition that leads to severe stroke. However, the surgical strategy for its treatment is controversial because the pathology is very complicated and varies in each case. Here, we report a case of bilateral VADA that was successfully treated with staged bilateral VADA occlusion and low-flow bypass.
CASE DESCRIPTION
A Japanese man in his 40s presented with bilateral VADA with subarachnoid hemorrhage. He had only mild headaches without any other neurological deficits. Subsequently, the ruptured left VADA was surgically trapped. However, on postoperative day 11, the contralateral VADA enlarged. The right VADA was then proximally clipped via a lateral suboccipital approach. Furthermore, a superficial temporal artery-superior cerebellar artery bypass was performed through a subtemporal approach in advance to preserve cerebral flow in the posterior circulation. The bilateral VADA was obliterated, and the patient had an uneventful postoperative course during the 1-year and 6-month follow-up period.
CONCLUSION
Bilateral VADA can be successfully treated with staged bilateral VADA obstruction and low-flow bypass. In this case, as the posterior communicating arteries were the fetal type and the precommunicating segments of the posterior cerebral arteries (P1) were hypoplastic, a low-flow bypass was used to supply the basilar and cerebellar arteries, except the posterior cerebral and posterior inferior cerebellar arteries. Furthermore, low-flow bypass is a less invasive option than high-flow bypass.

Observational Study
Discharge within 24 h, transvaginal natural orifice transluminal endoscopic surgery- more suitable for ambulatory surgery in gynecology procedures: a retrospective study.
BACKGROUND
Natural orifice transluminal endoscopic surgery (NOTES) is an achievement in the field of minimally invasive surgery. However, the vantage point of vaginal natural orifice transluminal endoscopic surgery (vNOTES) in gynecologicalprocedures remains unclear. The main purpose of this study was to compare vNOTES with laparo-endoscopic single-site surgery, and to determine which procedure is more suitable for ambulatory surgery in gynecologic procedures.
METHODS
This retrospective observational study was conducted at the Department of Gynecology, Chengdu Women's and Children's Central Hospital. The 207 enrolled patients had accepted vNOTES and laparo-endoscopic single-site surgery in gynecology procedures from February 2021 to March 2022. Surgically relevant information regarding patients who underwent ambulatory surgery was collected, and 64 females underwent vNOTES.
RESULTS
Multiple outcomes were analyzed in 207 patients. The Wilcoxon Rank-Sum test showed that there were statistically significant differences between the vNOTES and laparo-endoscopic single-site surgery groups in terms of postoperative pain score (0 vs. 1 scores, p = 0.026), duration of anesthesia (90 vs. 101 min, p = 0.025), surgery time (65 vs. 80 min, p = 0.015), estimated blood loss (20 vs. 40 mL, p < 0.001), and intestinal exhaustion time (12.20 vs. 17.14 h, p < 0.001). Treatment with vNOTES resulted in convenience, both with respect to time savings and hemorrhage volume in surgery and with respect to the quality of the prognosis.
CONCLUSION
These comprehensive data reveal the capacity of vNOTES to increase surgical efficiency. vNOTES in gynecological procedures may demonstrate sufficient feasibility and provide a new medical strategy compared with laparo-endoscopic single-site surgery for ambulatory surgery in gynecological procedures.

AIMS
Infection is a common complication following acute ischemic stroke (AIS) and significantly contributes to poor functional outcomes after stroke. This study aimed to investigate the effects of infection after endovascular treatment (post-EVT infection) on clinical outcomes and risk factors in patients with AIS.
METHODS
We retrospectively analyzed AIS patients treated with endovascular treatment (EVT) between January 2016 and December 2022. A post-EVT infection was defined as any infection diagnosed within 7 days after EVT. The primary outcome was functional independence, defined as a modified Rankin scale (mRS) score of 0-2 at 90 days. A multivariable logistic regression analysis was conducted to determine independent predictors of post-EVT infection and the associations between post-EVT infection and clinical outcomes.
RESULTS
A total of 675 patients were included in the analysis; 306 (45.3%) of them had post-EVT infections. Patients with post-EVT infection had a lower rate of functional independence than patients without infection (31% vs 65%, p = 0.006). In addition, patients with post-EVT infection achieved less early neurological improvement (ENI) after EVT (25.8% vs 47.4%, p < 0.001). For safety outcomes, the infection group had a higher incidence of any intracranial hemorrhage (23.9% vs 15.7%, p = 0.01) and symptomatic intracranial hemorrhage (10.1% vs 5.1%, p = 0.01). Unsuccessful recanalization (aOR 1.87, 95% CI 1.11-3.13; p = 0.02) and general anesthesia (aOR 2.22, 95% CI 1.25-3.95; p = 0.01) were identified as independent predictors for post-EVT infection in logistic regression analysis.
CONCLUSION
AIS patients who develop post-EVT infections are more likely to experience poor clinical outcomes. Unsuccessful recanalization and general anesthesia were independent risk factors for the development of post-EVT infection.

Pituitary apoplexy is a rare and severe complication of pituitary adenoma that may present with new-onset headache, ocular palsy, visual disturbances, life-threatening electrolyte imbalance, and endocrinological disturbances due to pituitary hemorrhage and/or infarction. We report the case of a 58-year-old previously healthy patient who developed isolated mild oculomotor nerve palsy of the left eye following osteosynthesis of a traumatic right distal radius fracture. Initial cerebral magnetic resonance imaging showed a pituitary macroadenoma without characteristic signs of pituitary infarction or hemorrhage. The patient presented to the neurology department on the fifth postoperative day with malaise and fatigue due to pituitary insufficiency, deteriorated rapidly and required intensive care monitoring. Clinical stabilization was achieved through the administration of hydrocortisone, and transsphenoidal resection of the pituitary lesion was performed on the 10th day after acute symptom onset. Histological examination revealed a necrotic pituitary adenoma. Pituitary apoplexy may occur after minor surgery in patients with pituitary adenoma. Clinicians should pay particular attention to laboratory signs of pituitary insufficiency in new-onset oculomotor nerve palsy associated with sellar lesions, as cerebral imaging may miss pituitary apoplexy and therefore delay diagnosis and treatment. In our case, delayed decompressive transsphenoidal resection resulted in the normalization of the oculomotor nerve palsy while the pituitary insufficiency persisted. The potential impact of an earlier surgical intervention on the outcome of pituitary function remains uncertain.

BACKGROUND
Diffuse alveolar hemorrhage (DAH) is a potentially life-threatening condition that can occur due to a variety of disorders. Hence, rapid diagnosis and prompt initiation of appropriate treatment are imperative.
CASES
A 55-year-old woman with a deep neck infection underwent emergent tonsillectomy. General anesthesia and surgery proceeded uneventfully. Upon transfer to the post-anesthesia care unit, ongoing respiratory distress and occasional expectoration of blood-tinged sputum were noted. Lung ultrasonography (LUS) revealed multiple B-profiles and irregular pleural lines with subpleural consolidations. Emergent bronchoscopy with bronchoalveolar lavage was diagnostic of DAH. She underwent a comprehensive evaluation for rheumatologic and infectious etiologies of DAH, all of which yielded negative results. The patient was managed with steroids and conservative treatment.
CONCLUSIONS
The integration of LUS with clinical information allows for more rapid differentiation of acute respiratory failure causes. Therefore, anesthesiologists' awareness and utilization of LUS findings of DAH can significantly contribute to appropriate management.
