BACKGROUND
The establishment of preoperative chemotherapy (PCT) with FOLFIRINOX and gemcitabine/nab-paclitaxel in recent years has enabled resectability in many patients with initially locally advanced pancreatic cancer (LAPC). Nevertheless, information about the impact of PCT on surgical results is scarce.
METHODS
All patients with initial LAPC who received surgery after chemotherapy at the high-volume centre for pancreatic surgery of St. Josef-Hospital Bochum between 2015 and 2022 were included in this retrospective cohort analysis.
RESULTS
A total of 139 patients underwent surgery after pre-treatment with FOLFIRINOX (76.3%), gemcitabine/nab-paclitaxel (11.5%), both (5.8%) and other regimens (6.5%). Eighty-five tumors (61.2%) were resectable after PCT. R0 resection was achieved in 92.9%, R1 in 7.1% and R2 in 0% of cases. Fifty-four tumors were still not resectable at the time of surgery. Surgical results of the patients did not show increased postoperative mortality and morbidity compared to the literature data. Postoperative 30-day mortality was 1.4%. Rates for pancreas-specific complications [postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), postpancreatectomy hemorrhage (PPH), and others] were not increased. POPF occurred in 10.5% and DGE in 26.3% after pancreaticoduodenectomy. After distal pancreatectomy, POPF was detected in 37.5% and DGE in 12.5%. Median postoperative survival (31 13 months) and overall survival after initial diagnosis (40 20 months) were significantly longer in resected patients (P<0.001). Postoperative recurrence-free survival in resected patients amounted to 12 months.
CONCLUSIONS
This study underlines that PCT allows resectability of primarily unresectable patients with LAPC without increasing perioperative mortality and morbidity. It may lead to a significant prolongation of recurrence-free and overall survival in resected patients after PCT.

INTRODUCTION
Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors, with jejunal GISTs being particularly uncommon. Jejunal GISTs causing perforation and acute diffuse peritonitis is rare.
CASE PRESENTATION
A 53-year-old female with a history of hypertension presented with severe, acute abdominal pain and vomiting. Examination revealed abdominal distension, tenderness, and guarding, with imaging suggestive of gastrointestinal perforation. Emergency laparotomy revealed a 9 cm × 8 cm mass with perforation in the jejunum, which was resected which on histopathological examination confirmed a low-grade GIST. The postoperative course was complicated by a wound infection, managed with antibiotics and secondary suturing. At one-year follow-up, the patient remained disease-free without the need for adjuvant therapy.
CLINICAL DISCUSSION
The most common symptoms of jejunal GISTs include vague abdominal pain or discomfort, early satiety, obstruction or hemorrhage. Preoperative diagnosis and confirmation of GIST is difficult due to nonspecific symptoms and none of the radiographic procedures can establish the diagnosis with certainty. The surgical excision of the tumor along with infiltrated tissues is the treatment of choice for GIST.
CONCLUSION
This case underscores the necessity of considering GISTs in differential diagnoses of acute abdomen and the critical role of prompt surgical management and multidisciplinary care in achieving favorable outcomes.

Randomized Controlled Trial Comparative Study
BACKGROUND
Observational studies have shown reduced perioperative bleeding in patients undergoing minimally invasive, compared with full sternotomy, aortic valve replacement. Data from randomized trials are conflicting.
METHODS
This was a Swedish single center study where adult patients with aortic stenosis, 100 patients were randomly assigned in a 1:1 ratio to undergo either minimally invasive (ministernotomy) or full sternotomy aortic valve replacement. The primary outcome was severe or massive bleeding defined by the Universal Definition of Perioperative Bleeding in adult cardiac surgery (UDPB). Secondary outcomes included blood product transfusions, chest tube output, re-exploration for bleeding, and several other clinically relevant events.
RESULTS
Out of 100 patients, three patients randomized to ministernotomy were intraoperatively converted to full sternotomy (none was bleeding-related). Three patients (6%) in the full sternotomy group and 3 patients (6%) in the ministernotomy group suffered severe or massive postoperative bleeding according to the UDPB definition (p = 1.00). Mean chest tube output during the first 12 postoperative hours was 350 (standard deviation (SD) 220) ml in the full sternotomy group and 270 (SD 190) ml in the ministernotomy group (p = 0.08). 28% of patients in the full sternotomy group and 36% of patients in the ministernotomy group received at least one packed red blood cells transfusion (p = 0.39). Two patients in each group (4%) underwent re-exploration for bleeding.
CONCLUSIONS
Minimally invasive aortic valve replacement did not result in less bleeding-related outcomes compared to full sternotomy.

Journal of Dentistry Jun 2024This randomized clinical trial aimed to assess the feasibility of computer-assisted open exposure of palatally impacted canines.
OBJECTIVE
This randomized clinical trial aimed to assess the feasibility of computer-assisted open exposure of palatally impacted canines.
MATERIALS AND METHODS
Patients aged 11-30 years who required orthodontic eruption for the full palatal impaction of their canines were included in this study. Exclusion criteria were psychosocial and dental contraindications of orthodontic treatment, congenital craniofacial disorders, and trauma in the patient's history in the vicinity of the surgical site. Virtual planning software was used to register the intraoral scans and cone-beam computed tomography data and to design a surgical template. In the test group, exposure of the canines was guided by a surgical template, whereas in the control group, the surgeon relied on the surgical plan to localize the impacted canine. The success of the intervention, duration of surgery, and complications, including excessive hemorrhage, damage to the canine or neighboring anatomical landmarks, and postoperative inflammation of the surgical site were assessed. Postoperative pain was reported by the patients using the visual analog pain scale (VAS).
RESULTS
Surgery was deemed successful in all patients in both groups. During healing, no complications were observed. The duration of surgery decreased significantly in the test group (4 min 45.1 s ± 1 min 8.4 s) compared to that in the control group (7 min 22.3 s ± 56.02 s). No statistically significant differences were observed between the VAS scores of the two study groups.
CONCLUSIONS
The application of virtual planning and static navigation is a viable approach for the open exposure of palatally impacted canines.
CLINICAL TRIAL REGISTRATION NUMBER
NCT05909254.
CLINICAL SIGNIFICANCE
Computer-assisted surgery is a feasible method for open exposure of palatally impacted canines, which decreases the duration of surgery compared to the freehand method.

BACKGROUND
Vertebral artery stump syndrome (VASS) is a cause of acute stroke. Owing to the particularity of the pathogenesis of VASS, interventional treatment of VASS is difficult. Common mechanical thrombectomy approaches include femoral and radial artery approaches. However, conventional approaches may not be suitable for VASS. If effective measures are not taken to open offending vessels in time, this can lead to a high rate of disability. In recent years, no consensus has been reached regarding surgical methods for treating VASS.
PATIENT CONCERNS
The patient presented to the emergency department with a 2-hour history of disturbance of consciousness.
DIAGNOSIS
After neurological and magnetic resonance imaging examinations, the patient was diagnosed with acute large vessel occlusive posterior circulation cerebral infarction.
METHODS
The patient's symptoms were not relieved after intravenous infusion of argatroban (10 mg) at a local hospital. We first attempted to open the occluded vertebral artery through normal approaches but failed. We then punctured the vertebral artery, successfully opened the occluded vertebral artery, and performed mechanical thrombectomy.
RESULTS
The patient underwent successful vertebral artery puncture and mechanical thrombectomy, with no evidence of postoperative bleeding or vascular injury at the puncture site. The patient regained consciousness the day after surgery but remained impaired in physical activity. After 4 months of rehabilitation, the patient recovered completely.
CONCLUSION
When the conventional approach cannot meet the requirements of mechanical thrombectomy, reverse puncture of the vertebral artery is a feasible surgical method for patients with VASS. However, due to the small number of cases, a series of safety problems such as potential puncture failure, hemorrhage after puncture, and vascular occlusion still need to be further explored.

BACKGROUND
Restless legs syndrome (RLS) is a neurological sensorimotor disorder characterized by an uncontrollable urge to move the legs. In the perioperative period, patients with RLS may experience an acute exacerbation of symptoms. Although studies on the exacerbation of RLS after brain surgery are limited, we present a case wherein symptoms worsened following left amygdalohippocampectomy.
CASE PRESENTATION
A 58-year-old woman diagnosed with mesiotemporal lobe epilepsy accompanied by left hippocampal sclerosis underwent a left amygdalohippocampectomy. The patient reported uncomfortable sensations in the lower limbs preoperatively. However, the urge to move her legs was manageable and not distinctly diagnosed with RLS. The symptoms began to deteriorate on the fifth postoperative day primarily affecting the legs and back, with a notable emphasis on the right side. Pramipexole treatment effectively ameliorated these symptoms.
CONCLUSION
No reports are available highlighting the exacerbation of RLS after amygdalohippocampectomy. Perioperative factors, such as anesthesia and iron deficiency due to hemorrhage, have been proposed as aggravating factors for RLS; however, the asymmetry of RLS, particularly the atypical right-sided exacerbation in this case, makes it unlikely that this was the primary cause. A negative correlation between opioid receptor availability in the amygdala and RLS severity has been reported, suggesting that amygdalohippocampectomy contributes to the exacerbation of RLS symptoms. This case provides valuable insights into the possible involvement of the amygdala in the pathophysiology of RLS and practical considerations for the clinical management of the condition.

Role of the WHO Surgical Safety Checklist in Reducing Morbidity and Mortality Among Obstetrics and Gynecology Patients Undergoing Surgery: A Prospective Comparative Study.
BACKGROUND
As surgery is an essential aspect of healthcare around the globe, it is necessary to consider complications related to it. Therefore, this study was conducted to evaluate the impact of the World Health Organization Surgical Safety Checklist (WHO SSC) on reducing the incidence of postoperative complications Methods This single-center, prospective, comparative study was conducted at the Department of Gynecology and Obstetrics in a government hospital in Patna, Bihar. To assess the efficacy of the WHO SSC, the patients were divided into two groups, in which one group undergoing surgery was assessed with the checklist, and the other group was not. The rates of surgery-related complications were then compared in both groups.
RESULTS
Our results showed a reduction in surgery-related complications in patients assessed with the WHO SSC. No statistically significant difference in duration of surgery was found between the groups. However, a statistically significant difference was observed in the rates of surgery-related complications between groups, especially in sepsis (p0.0009), hemorrhage (p0.0001), and infection at the site of surgery (p0.0001). Mortality rates were not affected by the use of the SSC.
CONCLUSION
The WHO SSC is a simple yet effective tool for reducing postoperative complications by improving communication between the various team members working in the operation theatre, although it has no effect on reducing mortality. Further research is needed to enhance its successful implementation and ensure its sustained use.

INTRODUCTION
Clazosentan, a selective endothelin receptor subtype A antagonist, reduces vasospasm-related morbidity and all-cause mortality following aneurysmal subarachnoid hemorrhage (SAH) in the Japanese population, as demonstrated by a recent randomized phase 3 trial. However, evidence to suggest clazosentan should be prioritized over the current standard of care to prevent cerebral vasospasm is still lacking. Therefore, we investigated the efficacy and safety of clazosentan in comparison with conventional postoperative management in real-world clinical practice.
METHODS
We conducted a single-center, retrospective, observational cohort study using prospectively collected data from consecutive patients with aneurysmal SAH. After clazosentan was approved for use in Japan, the conventional postoperative management protocol, composed of intravenous fasudil chloride and oral cilostazol (control group, April 2021 to March 2022), was changed to the clazosentan protocol (clazosentan group, April 2022 to March 2023). The primary endpoint was the incidence of vasospasm-related symptomatic infarction. The secondary endpoints were favorable functional outcomes (modified Rankin scale score < 3) at discharge, angiographic vasospasm, and the need for rescue therapy for delayed cerebral ischemia.
RESULTS
The analysis included 100 and 81 patients in the control and clazosentan groups, respectively. The incidence of vasospasm-related symptomatic infarction was significantly lower in the clazosentan group than in the control group (6.2% vs. 16%, = 0.032). Multiple logistic analyses demonstrated that the use of clazosentan was independently associated with fewer incidence of vasospasm-related symptomatic infarct (23.8% vs. 47.5%, odds ratio 0.34 [0.12-0.97], = 0.032). Clazosentan was significantly associated with favorable outcomes at discharge (79% vs. 66%, = 0.037). Moreover, both the incidence of angiographic vasospasm (25.9% vs. 44%, = 0.013) and the need for rescue therapy (16.1% vs. 34%, = 0.006) was lower in the clazosentan group. The occurrence of pulmonary edema was significantly higher with clazosentan use (19.8% vs. 5%, = 0.002), which did not result in morbidity.
CONCLUSION
A postoperative management protocol centering on clazosentan was associated with the reduced vasospasm-related symptomatic infarction and improved clinical outcomes compared to the conventional management protocol in Japanese clinical practice. Clazosentan might be a promising treatment option for counteracting cerebral vasospasm after aneurysmal SAH.

Bleeding is still one of the most feared intraoperative and postoperative complications that can lead to an increase in morbidity, mortality, length of hospital stay and costs. Nowadays, in addition to accurate surgical techniques, several local haemostatic agents are available and can be used in case of oozing bleeding. Herein, we report our experience with a ready-to-use polysaccharide powder in two patients undergoing distal splenopancreatectomy. Bleeding control was achieved in both cases. No patient showed postoperative bleeding, and no other complications were reported.

Tourette syndrome (TS) is a developmental neuropsychiatric disorder that is characterized by tic movements. Deep brain stimulation (DBS) may be a treatment option for severe cases refractory to medical and behavioral therapies. In this study, we reviewed the surgical techniques used for DBS in patients with severe TS and its clinical outcomes and sought to determine the optimal surgical procedure and current issues based on our experience and the literature. A total of 14 patients, consisting of 13 men and 1 woman, who underwent centromedian thalamic DBS and were followed up for a mean duration of 2.3 ± 1.0 years, participated in this study. The mean Yale Global Tic Severity Scale severity score significantly improved from 41.4 ± 7.0 at baseline to 19.8 ± 11.4 at 6 months (P = 0.01) and 12.7 ± 6.2 at the last follow-up (P < 0.01). Moreover, the mean Yale Global Tic Severity Scale impairment score significantly improved from 47.1 ± 4.7 at baseline to 23.1 ± 11.1 at 6 months (P < 0.01) and 7.6 ± 2.9 at the last follow-up (P < 0.01). However, there were problems with continuous postoperative monitoring (three cases were lost to follow-up) and surgery-related adverse events, including one case each of lead misplacement and a delayed intracerebral hemorrhage due to severe self-injurious tics. This study aimed to highlight not only the clinical efficacy of DBS for TS but also its challenges. Clinicians should understand the three-dimensional brain anatomy so that they can perform precise surgical procedures, avoid adverse events, and achieve favorable outcomes of DBS for TS.
