RATIONALE: Raney clips are commonly used in neurosurgical procedures to hold the scalp in place and stop bleeding during surgery. The removal of Raney clips is often the last process during cranial surgery prior to the closure of skin incision. Thus, a Raney clip found underneath the titanium mesh resulting in fever is a very rare occurrence. PATIENT CONCERNS: An 18-year-old male patient underwent cranial surgery due to intracranial abscess in the frontal lobe and subsequently underwent frontal skull repair using titanium mesh during which a Raney clip was unintentional left underneath the titanium mesh resulting in fever. DIAGNOSIS: A thin-slice computed tomography (CT) scan was used to identify the Raney clip. INTERVENTION: A third surgery was performed to remove the Raney clip. OUTCOMES: The patient fever total resolved after the third surgery with no further neurological deficits and 2-years follow-up revealed the patient is well and go about his daily activities. LESSONS: It is crucial to ensure that all foreign objects are removed after the surgery by counting all instruments used at and after each step during the operation, including all Raney clips. This will help prevent complications and ensure the safety as well as the well-being of the patient.

BACKGROUND: Acute non-variceal upper gastrointestinal bleeding (UGIB) is challenging in patients at high risk of re-bleeding in whom standard endoscopic treatment (ST) has limited effectiveness. Over-the-scope clips (OTSC) have shown promise in these patients although their precise role remains uncertain. AIMS: To confirm the role of OTSC in patients with UGIB at high risk of re-bleeding. METHODS: We systematically searched CENTRAL, MEDLINE and Embase from January 1st, 1970 to April 24, 2024 for randomised controlled trials (RCTs) comparing OTSC and ST in acute non-variceal UGIB with high re-bleeding risk. The GRADE framework assessed evidence certainty, while trial sequential analysis (TSA) controlled random errors and evaluated conclusion validity. RESULTS: We analysed four RCTs (319 patients); pooled risk ratio (RR) for clinical success at initial endoscopy favoured OTSC (RR = 1.30, 95% CI = 1.08-1.56, p = 0.006, I2 = 58%, moderate certainty of evidence). TSA showed the desired sample size was 410 and the cumulative Z curve crossing the trial sequential monitoring boundary. The pooled RR for re-bleeding within 30 days favoured OTSC (RR = 0.53, 95% CI = 0.30-0.94, p = 0.03, I2 = 0%, moderate certainty of evidence). There was no significant difference in 30-day mortality, or length of hospital or ICU stay. CONCLUSIONS: Moderate certainty evidence supports OTSC as a superior initial treatment for acute non-variceal UGIB with high re-bleeding risk. Further large-scale studies are needed to confirm OTSCs' role by exploring other prognostic outcomes and assessing cost-effectiveness and potential complications.

BACKGROUND: The current literature supports the closure of trocar sites ≥10-mm for the risk of developing incisional hernias, while there is no need to suture the abdominal fascia when using 5-mm trocars. To date, evidence regarding the closure of 8-mm trocars that are use by new robotic systems is weak. The aim of our study was to investigate the incidence of incisional hernia for 8-mm trocars. METHODS: We prospectively collected data on all patients undergoing robotic-assisted abdominal wall surgery from 2020 to 2023, in whom the abdominal fascia of all 8-mm trocars was not closed. The enrolled patients underwent a follow-up visit during which we conducted clinical and sonographic evaluations of all 8-mm trocars, in addition to assessing the satisfaction levels of the patients. The primary outcome was the incidence of port-site hernia. RESULTS: We enrolled 166 patients, 155 men and 11 women, for a total of 513 trocars accessed. Mean age was 61.1 ± 14.0 years, and mean BMI was 27.0 ± 3.9 kg/m2. The follow-up visits were carried out after a median follow-up of 14.5 (9.0-23.2) months. Only one case developed an asymptomatic 1 × 1 cm supra-umbilical hernia that was not treated. Patient reported a satisfaction regarding the 8-mm trocars and skin sutures of 9.8 ± 0.5 out of 10 points. CONCLUSIONS: The occurrence of a trocar-site hernia after 8-mm robotic access is extremely low. Hence, the fascia closure may not be necessary.

BACKGROUND: The method of transecting the pancreatic parenchyma during pancreatic resection may influence the rate of complications, including pancreatic fistula and bleeding. The objective of this study was to compare the transection of the pancreatic parenchyma during pancreatoduodenectomy with monopolar electrocautery versus scalpel in terms of postoperative complications. METHODS: A retrospective analysis of patients with open pancreatoduodenectomy from the German DGAV StuDoQ|Pancreas registry (January 2013 to December 2021) was performed. Transection of the pancreatic parenchyma with a scalpel versus monopolar electrocautery was compared regarding postoperative pancreatic fistula B/C, post-pancreatectomy hemorrhage B/C, and major complications (Clavien-Dindo classification ≥3) rates. Multivariable analysis with adjustment for potential confounders and surgical center cluster effect was performed. RESULTS: Overall, 6,752 patients were included in the study. In 4,072 (60.3%), transection was performed with a scalpel and, in 2,680 (39.7%), with electrocautery. Transection with electrocautery was associated with higher postoperative pancreatic fistula B/C (15.4% vs 12.8%; P = .003), post-pancreatectomy hemorrhage B/C (11% vs 7.4%; P < .001), and major complications (33.4% vs 29.6%; P = .001) rates. In the multivariable analysis, after adjustment for potential confounders and surgical center, the association of the transection method with postoperative pancreatic fistula B/C (odds ratio = 1.01; 95% CI, 0.79-1.2; P = .962), post-pancreatectomy hemorrhage B/C (odds ratio = 1.23; 95% CI, 0.94-1.6; P = .127), and major complications (odds ratio = 1.09; 95% CI, 0.93-1.27; P = .297) was not significant. CONCLUSION: The study found no significant association between transection of the pancreatic parenchyma during open pancreatoduodenectomy with a scalpel compared with monopolar electrocautery regarding pancreatic fistula, postoperative bleeding, or overall major complication rates.

OBJECTIVES: To investigate the factors that contribute to the development of cerebral edema after aneurysm clipping in individuals with aneurysmal subarachnoid hemorrhage (aSAH). METHODS: A total of 232 patients with aSAH caused by rupture and treated with aneurysm clipping were included in the retrospective analysis of clinical data. Postoperatively, the participants were categorized into two groups based on the presence or absence of cerebral edema: a complication group (n=33) and a non-complication group (n=199).A comparison was made between the overall data of the 2 groups. RESULTS: In the complication group, there were higher proportions of patients experiencing recurrent bleeding, aneurysm in the posterior circulation, Fisher grade III-IV, World Federation of Neurosurgical Societies (WFNS) grade II, Hunt-Hess grade III-IV, concomitant hypertension, duration from onset to operation ≥12 h, and concomitant hematoma compared to the non-complication group (p<0.05). Cerebral edema after aneurysm clipping was associated with several risk factors including repeated bleeding, aneurysm in the back of the brain, Fisher grade III-IV, WFNS grade II, Hunt-Hess grade III-IV, simultaneous high blood pressure and hematoma, and a duration of at least 12 hours from the start of symptoms to the surgical procedure (p<0.05). CONCLUSION: In patients with aSAH, the risk of cerebral edema after aneurysm clipping is increased by recurrent bleeding, aneurysm in the posterior circulation, Fisher grade III-IV, WFNS grade II, Hunt-Hess grade III-IV, concomitant hypertension and hematoma, and duration of ≥12 h from onset to operation.

Oral anticoagulants for atrial fibrillation are the standard approach to prevent stroke in patients with atrial fibrillation. However, oral anticoagulant therapy carries the risk of cerebral infarction recurrence, not to mention hemorrhagic complications, even under appropriate drug therapy. Surgical treatments targeting the left atrial appendage include left atrial appendage closure( LAAO) and left atrial appendage resection (LAAR). Our hospital uses AtriClip (approved and available in Japan since 2018) as a device for LAAO, and we investigated the early and long-term results of LAAO using AtriClip in our hospital. As a result, stable early to long-term results were expected for left atrial appendage closure using AtriClip device, suggesting that it may be an option that can be considered as a method for preventing stroke in patients with atrial fibrillation. But further investigation is required in the future.

BACKGROUND: The aim of this study was to investigate 8-mm robotic trocar site hernia (TSH) rate over the short and long term, providing aids to manage the related fascial wounds. METHODS: A retrospective analysis of 320 patients undergoing robotic surgery was conducted. The primary outcome was 8-mm TSH rate with a minimum follow-up of 12 months. The secondary outcome was the rate of haematomas and infections related to 8-mm wounds and their association with patient comorbidities and trocar position. RESULTS: One case of TSH was observed (0.31%). There were 15 cases of wound infection (4.68%) and 22 cases of wound haematoma (6.87%). Trocar related complications were significantly associated with patient comorbidities, not with trocar position. CONCLUSIONS: Our results do not justify the 8-mm fascial wound closure. Data concerning the association between trocar-related complications and patient comorbidities strengthen the need to implement the control of metabolic state and correct administration of perioperative therapy in high-risk patients.

INTRODUCTION: With an incidence of 0-5.2%, trocar site hernias frequently occur following laparoscopy. It is unclear to what extent the angle of trocar insertion affects the size of the fascial defect caused. Hence, we performed a porcine model. METHODS: In October 2022, a total of five female pigs were euthanized. In alternating order, three bladeless and two bladed conical 12-mm trocars were inserted at an angle of 45° on each side for 60 min twice each pig. For this purpose, an epoxy resin handmade cuboid with a central channel that runs at an angle of 45° was used. Subsequently, photo imaging and defect size measurement took place. The results were compared with those of our previously conducted and published porcine model, in which the trocars were inserted at an angle of 90°. Effects of trocar type (bladed vs. bladeless) and angle on defect size were analyzed using a mixed model regression analysis. RESULTS: The bladeless trocars caused statistically significant smaller defects at the fascia than the bladed (23.4 (SD = 16.9) mm2 vs. 41.3 (SD = 14.8) mm2, p < 0.001). The bladeless VersaOne trocar caused the smallest defect of 16.0 (SD = 6.1) mm2. The bladed VersaOne trocar caused the largest defect of 47.7 (SD = 10.5) mm2. The defect size of the trocars used at a 45° angle averaged 30.5 (SD = 18.3) mm2. The defect size of trocars used at a 90° angle was significantly larger, averaging 58.3 (SD = 20.2) mm2 (p = 0.007). CONCLUSION: When conical 12-mm trocars are inserted at a 45° angle, especially bladeless ones, they appear to cause small fascial defects compared with insertion at a 90° angle. This might lead also to a lower rate of trocar hernias. Bladeless trocars might cause smaller fascial defects than bladed trocars.

Analyses of registries and medical imaging suggest that laparoscopic surgery may be penalized with a high incidence of trocar-site hernias (TSH). In addition to trocar diameter, the location of the surgical wound (SW) may affect TSH incidence. The intra-abdominal pressure (IAP) exerted on the abdominal wall (AW) might also influence the appearance of TSH. In the present study, we used finite element (FE) simulations to predict the influence of trocar location and SW characteristics (stiffness) on the mechanical behavior of the AW subject to an IAP. Two models of laparoscopy patterns on the AW, with trocars in the 5-12 mm range, were generated. FE simulations for IAP values within the 4 kPa-20 kPa range were carried out using the Code Aster open-source software. Different stiffness levels of the SW tissue were considered. We found that midline-located surgical wounds barely deformed, even though they moved outwards along with the regular LA tissue. Laterally located SWs hardly changed their location but they experienced significant variations in their volume and shape. The amount of deformation of lateral SWs was found to strongly depend on their stiffness. Trocar incisions placed in a LA with non-diastatic dimensions do not compromise its mechanical integrity. The more lateral the trocars are placed, the greater is their deformation, regardless of their size. Thus, to prevent TSH it might be advisable to close lateral trocars with a suture, or even use a prosthetic reinforcement depending on the patient's risk factors (e.g., obesity).

BACKGROUND: There is an ongoing lack of consensus among clinicians regarding on the optimal aneurysmal subarachnoid hemorrhage (aSAH) management approach between endovascular coiling and microsurgical clipping. METHODS: Comprehensive literature search for randomized controlled trials (RCTs) was conducted in Medline and Cochrane databases until January 1st, 2023 without language constraints. Effectivity outcomes included one-year mortality, one-year poor outcomes, and one-year complete aneurysmal occlusion, while safety outcomes comprised the incidence of vasospasms, rebleeding, post-operative complications, and cerebral ischemia. RESULTS: Eight RCTs, involving 3585 aSAH patients, underwent comprehensive quantitative analysis. Among them, 1792 underwent endovascular coiling and 1773 patients had microsurgical clipping. Regarding effectivity, the rates of one-year mortality (OR: 0.79, 95% CI: 0.61-1.03, p = 0.08) exhibited no significant difference. However, endovascular coiling demonstrated an inferior one-year complete aneurysmal occlusion rate (OR: 0.33, 95% CI: 0.21-0.53, p < 0.00001), although with significantly lower rates of poor outcomes (OR: 0.68, 95% CI: 0.57-0.81, p < 0.00001) compared to the microsurgical clipping group. As for safety, endovascular coiling group exhibited lower rates of vasospasm (OR: 0.58, 95% CI: 0.36-0.92, p = 0.02), post-operative complications (OR: 0.40, 95% CI: 0.23-0.71, p = 0.02), and cerebral ischemia (OR: 0.36, 95% CI: 0.20-0.63, p = 0.0004). No significant effect on the incidence of rebleeding was observed (OR: 1.09, 95% CI: 0.73-1.63, p = 0.68). CONCLUSIONS: Endovascular coiling proves superior and safer for aSAH patients, but consideration of resources, patient condition, and surgeon preferences is crucial for selecting the optimal approach.

OBJECTIVE: To understand the etiology of tracheotomy-induced tracheal stenosis by comparing the differences in techniques and mechanical force applied with open tracheotomy (OT) versus percutaneous tracheotomy (PCT) placement. METHODS: This study is an unblinded, experimental, randomized controlled study in an ex-vivo animal model. Simulated tracheostomies were performed on 10 porcine tracheas, 5 via a tracheal window technique (OT) and 5 using the Ciaglia technique (PCT). The applied weight during the simulated tracheostomy and the compression of the trachea were recorded at set times during the procedure. The applied weight during tracheostomy was used to calculate the tissue force in Newtons. Tracheal compression was measured by anterior-posterior distance compression and as percent change. RESULTS: Average forces for scalpel (OT) versus trocar (PCT) were 2.6 N and 12.5 N (p < 0.01), with the dilator (PCT) it was 22.02 N (p < 0.01). The tracheostomy placement with OT required an average force of 10.7 N versus 23.2 N (p < 0.01) with PCT. The average change in AP distance when using the scalpel versus trocar was 21%, and 44% (p < 0.01), with the dilator it was 75% (p < 0.01). The trach placement with OT versus PCT had an average AP distance change of 51% and 83% respectively (p < 0.01). CONCLUSION: This study demonstrated that PCT required more force and caused more tracheal lumen compression when compared to the OT technique. Based on the increased force required for PCT, we suspect there could also be an increased risk for tracheal cartilage trauma. LEVEL OF EVIDENCE: NA Laryngoscope, 134:103-107, 2024.

BACKGROUND: Clips are endoscopic mechanical devices with tensile and closure strength that can approximate tissue and provide hemostasis through a tamponade effect. Clips are ubiquitously used in endoscopic practice, and numerous studies have validated the clinical efficacy of clips, with recent guidelines recommending them as a first-line intervention for recurrent and persistent nonvariceal gastrointestinal bleeding. However, the safety profile for these devices has yet to be delineated, thus, we aim to investigate this feature by examining the adverse events reported to the Food and Drug Administration. METHODS: Postmarketing surveillance data from the Food and Drug Administration Manufacturer And User Facility Device Experience database were analyzed from January 2012 to January 2021. The Manufacturer And User Facility Device Experience database is a reporting software and does not independently verify the details of complications. RESULTS: Two thousand five hundred forty reports were issued, of which 287 were patient adverse events and 2766 were device problems. Activation, separation, and positioning issues were most common. No consequences or clinically significant impact on patients were seen in 1968 reports. Foreign bodies were seen in 97 cases, hemorrhage in 57 cases, tissue damage in 42 cases, embedded clips in tissues/plaques in 16 cases, perforation in 15 cases, lacerations in 6 cases, and infection in 3 cases. CONCLUSIONS: While the most commonly reported device problems involved activation, separation, and positioning, most patients were clinically unaffected. Moreover, perforation and infection were exceedingly rare, further highlighting the safety profile of endoscopic clips.

OBJECTIVES: Topic treatment can be useful to improve short and long-term nasal outcomes after nasal surgery, reducing discomfort and risk of synechia. This study aimed at evaluating the effect on clinical outcomes of nasal packaging using Fitostimoline® gauze in FESS and septoplasty. METHODS: A case-control study on hospitalized patients was performed in a tertiary referral center. The control group included 20 patients treated with the standard surgical protocol for septoplasty and standard nasal packaging; treatment group included 21 patients underwent same surgical procedure but in whom the nasal tampon was wrapped with a gauze containing Fitostimoline® before being placed into the nose. RESULTS: Patients in treatment group had better outcomes than control; nasal mucosa showed better healing - recovery of normal color- in those patients in whom we applied the Fitostimoline® gauze around tampons. Moreover, 100 % patients in the treatment group did not refer discomfort during at tampon removal versus 60 % subjects in the control group who referred pain, tension or tearing during the same action. CONCLUSION: Our results, although preliminary because of the small cohort of subjects included, suggest that the apposition of a gauze with Fitostimoline® after nasal surgery might improve the mucosal healing with consequent reduction of patients discomfort during the post-surgical period.

BACKGROUND: The aim of this study was to investigate the incidence, risk factors, clinical presentation, and management of major vascular injuries during bariatric surgery, with a specific focus on the role of different access methods in abdominal cavity entry. METHODS: A nationwide survey was conducted among bariatric surgeons to assess the prevalence of major vascular injuries. A questionnaire was distributed to 365 surgeons through WhatsApp groups of two national bariatric surgery societies, with 76 surgeons completing the survey. The study population included general surgeons practicing bariatric surgery, and the questionnaire consisted of 12 questions. RESULTS: Among the participants, 16.9% reported experiencing a major vascular injury during bariatric surgery. The majority of injuries (75%) occurred at the trocar entrance, with the remaining cases during the dissection phase. Notably, 66.7% of surgeons used optical trocars for access, while 27.8% employed the Veress needle technique. Early detection varied, with 45% identifying the injury immediately and 30% recognizing it within three minutes. Most injuries (52.4%) were repaired laparoscopically, and only three surgeons sought assistance from cardiovascular surgeons. CONCLUSION: Vascular injuries are infrequent but potentially serious complications in laparoscopic bariatric surgery. Understand-ing their incidence, timely recognition, and proper management are crucial to minimize adverse effects. The findings of this study shed light on the patterns of vascular injuries and the potential role of specific access methods, providing valuable insights for enhancing patient safety in bariatric surgery.

Intraoperative rupture is the most important complication of aneurysm surgery1-5 and occurs in 3 different stages: premature (before dissection), dissection, and clipping.5 We present a video of premature rupture and its management (Video 1). A 45-year-old patient presented with subarachnoid hemorrhage originating from a dorsal internal carotid artery (ICA) aneurysm of the communicating segment. Due to our sufficient experience, we preferred direct clipping in this case. The Sylvian fissure could only be partially opened due to excessive adhesions. During retraction of the frontal lobe, severe bleeding occurred. This was a premature rupture since neither the aneurysm nor the ICA had yet been seen. While aspirating the bleeding just over the rupture site with the left hand, the ICA was explored with the right hand and a temporary clip was placed. The bleeding continued, though it decreased. The aneurysm dome was rapidly explored with 1 hand, and a pilot clip was placed on the dome to stop the bleeding. Immediately afterwards, the aneurysm neck was dissected and clipped parallel to the ICA with a sideward clip. The temporary clip and pilot clip were removed. The temporary occlusion time was 7 minutes and 40 seconds. Postoperative angiogram confirmed complete aneurysm occlusion. The patient discharged with normal neurologic examination. In the literature review including 10,540 cases,1 the mean incidence of IOR is 16.6%. Therefore every neurosurgeon should be prepared for this important complication and know its management well. This case reminds us once again the golden rule of aneurysm surgery: proximal control first.

Delayed foreign body reactions to either or both clipping and coating materials have been reported in several small series; however, studies in the titanium clip era are scarce. This study aims to survey the contemporary status of such reactions to titanium clips and coating materials. Among patients who received a total of 2327 unruptured cerebral aneurysmal surgeries, 12 developed delayed intraparenchymal reactions during outpatient magnetic resonance imaging (MRI) follow-up. A retrospective investigation was conducted. The patients' average age was 58.6 (45-73) years, and 11 were women. The aneurysms were located in the middle cerebral artery (n = 7), internal carotid artery (n = 4), or anterior communicating artery (AComA, n = 1). In 10 patients, additional coating with tiny cotton fragments was applied to the residual neck after clipping with titanium clips; however, only the clipping with titanium clips was performed in the remaining two. The median time from surgery to diagnosis was 4.5 (0.3-60) months. Seven (58.3%) patients were asymptomatic, and three developed neurological deficits. MRI findings were characterized by a solid- or rim-enhancing lobulated mass adjacent to the clip with surrounding parenchymal edema. In 11 patients, the lesions reduced in size or disappeared; however, in one patient, an AComA aneurysm was exacerbated, necessitating its removal along with optic nerve decompression. In conclusion, cotton material is a strongly suspected cause of delayed foreign body reactions, and although extremely rare, titanium clips alone may also induce such a reaction. The prognosis is relatively good with steroid therapy; however, caution is required when the aneurysm is close to the optic nerve, as in AComA aneurysms.
