ABSTRACT
ObjectiveTo investigate the safety and efficacy of endoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips in the treatment of cirrhotic patients with gastric varices and gastric-renal shunt （GRS）. MethodsThe patients who attended Beijing Ditan Hospital， Capital Medical University， due to liver cirrhosis and gastric varices from February to June 2023 were enrolled， and all patients were confirmed to have GRS and received endoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips. The primary evaluation index was alleviation or disappearance of varicose veins after surgery， and the secondary evaluation indices were surgical completion and complications. ResultsA total of 11 patients were enrolled in this study， among whom there were 7 male patients and 4 female patients， with a median age of 55 years. Of all patients， 1 had Child class A liver function， 7 had Child class B liver function， and 3 had Child class C liver function. The maximum （median） diameter of the shunt was 8 mm， and the minimum （median） diameter of the shunt was 4 mm. The median blood flow velocity of the target vessel was 11 cm/s before treatment and 5 cm/s after occlusion with metal clips. The median amount of tissue adhesive injected was 2 mL， and the amount of lauromacrogol used was 1 mL. Disappearance of blood flow signals was observed in all patients after surgery （100%）， and the success rate of surgery was 100%. No patient experienced rebleeding after follow-up for 6 weeks. Gastroscopy at 1 month after surgery showed that gastric varices were eradicated or almost disappeared in 9 patients and were alleviated in 2 patients. ConclusionEndoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips is a feasible， safe， and effective treatment method for cirrhotic patients with gastric varices and GRS.
ABSTRACT
Nasal splint application is an important step of septal corrective surgeries to keep the septum in midline after the surgery. Septal clip is most commonly used. In our study we have compared the use of nasal septal clip and Merocel application post surgery and the morbidities associated with it.
ABSTRACT
Objective:To compare the efficacy of domestic and imported hemostatic clips in preventing delayed post-polypectomy bleeding (DPPB) after endoscopic resection of colorectal polyps ≥ 10 mm.Methods:Clinical data of 789 patients who underwent endoscopic resection of colorectal polyps (polyp diameter ≥10 mm) in Beijing Friendship Hospital, Capital Medical University from January 2018 to December 2019 were collected. The patients were divided into DPPB group ( n=15) and non-DPPB group ( n=774). Univariate and multivariate logistic regression models were used to analyze the influential factors for DPPB. The patients using one type of hemostatic clip were divided into the domestic hemostatic clip group ( n=499) and the imported hemostatic clip group ( n=208). The efficacy of hemostatic clips in preventing DPPB in the two groups was compared. Results:Among the 789 patients undergoing endoscopic resection of colorectal polyps, 1.9% (15/789) suffered from DPPB. Multivariate logistic regression analysis showed that pedunculated polyp was an independent risk factor for DPPB ( OR=6.621, 95% CI: 2.278-19.241, P=0.001), and closure of mucosal defect was an independent protective factor for DPPB ( OR=0.169,95% CI: 0.050-0.570, P=0.004). Regardless of physician experience, there was no significant difference between the domestic and imported hemostatic clip group in preventing DPPB after endoscopic resection of colorectal polyps ≥10 mm [experienced physicians: 1.8% (7/385) VS 0.6% (1/175), χ2=1.314, P=0.445; common physicians: 2.6% (3/114) VS 3.0% (1/33), χ2=0.010, P>0.999]. The domestic hemostatic clip group paid for less medical expenses than the imported hemostatic clip group (experienced physicians: 1 433.51±889.02 yuan VS 3 033.97±1 686.87 yuan, t<0.001 , P<0.001; common physicians: 1 181.58±815.29 yuan VS 3 303.46±1 690.43 yuan, t<0.001 ,P<0.001). Conclusion:Pedunculated polyp is an independent risk factor for DPPB after endoscopic resection of colorectal polyp larger than 10 mm, and clipping can significantly reduce the risk for DPPB. There is no significant difference in the prevention of DPPB between domestic and imported clips, but domestic clips compared with imported clips yield less medical burden, which are suitable for promotion to primary hospitals and major clinical centers.
ABSTRACT
Resumen Se reporta el caso de un hombre de 25 años con diagnóstico de tumor de células germinales no seminomatoso que ingresó a urgencias por cuadro clínico de dolor abdominal difuso asociado con distensión y múltiples episodios eméticos. Ante la sospecha clínica de obstrucción intestinal se realizó una tomografía abdominal contrastada que mostró una obstrucción en la tercera porción duodenal por compresión extrínseca ocasionada por múltiples conglomerados retroperitoneales. Se decidió el tiempo quirúrgico para una derivación gastrointestinal en la que se realizó una gastroyeyunoanastomosis por técnica convencional; hacia el quinto día posoperatorio presentó un deterioro clínico dado por episodios febriles, dolor abdominal y taquicardia. Se realizó una nueva tomografía abdominal que reportó una colección intraabdominal en el flanco izquierdo de 12 x 12 x 5 cm secundaria a proceso fistuloso yeyunal, se realizó un manejo de la colección con drenaje percutáneo por radiología intervencionista y alojamiento de catéteres de drenaje, y se realizó una esofagogastroduodenoscopia con el fin de ejecutar una técnica de exclusión pilórica con dispositivo Ovesco (over-the-scope) como manejo de la fístula yeyunal, con la que se obtuvo éxito técnico. Durante el posoperatorio se realizó como seguimiento una radiografía de vías digestivas que confirmó la no continuidad pilórica con adecuada permeabilidad de la gastroyeyunoanastomosis, y una tomografía abdominal contrastada que mostró una disminución de la colección intraabdominal sin extravasaciones del medio de contraste. El desenlace favorable de este caso sugiere la utilidad del dispositivo Ovesco en casos de fístulas del tracto gastrointestinal proximal, sobre todo en aquellos pacientes con múltiples comorbilidades o mal estado general que se favorecen de procedimientos mínimamente invasivos que disminuyan el riesgo de desenlace fatal.
Abstract A 25-year-old man diagnosed with a non-seminomatous germ cell tumor was admitted to the emergency department for diffuse abdominal pain associated with bloating and multiple emetic episodes. Due to the clinical suspicion of intestinal obstruction, a contrasted abdominal tomography was performed, showing an obstruction in the third duodenal portion resulting from extrinsic compression caused by multiple retroperitoneal conglomerates. Surgical time was scheduled for a gastric bypass surgery where gastrojejunostomy was performed using conventional technique. On the fifth postoperative day, he presented clinical deterioration due to febrile episodes, abdominal pain, and tachycardia. A new abdominal tomography was performed, reporting an intra-abdominal collection of pus on the left flank of 12 x 12 x 5 cm secondary to the jejunal fistula process. Hence, percutaneous drainage management of the collection was performed by interventional radiology and drainage catheter placement. In addition, an EGD was performed to conduct a pyloric exclusion technique with an Ovesco (over-the-scope-clip) device for managing the jejunal fistula, which was technically successful. A gastrointestinal tract X-ray was performed as a follow-up during the postoperative stage, showing no pyloric continuity with adequate patency of the gastrojejunostomy. In addition, a contrasted abdominal CT scan showed a decrease in the intra-abdominal collection without extravasation of the contrast medium. This case outcome suggests the Ovesco device may be helpful in proximal GI fistulas cases, especially in patients with multiple comorbidities or poor general conditions who may benefit from minimally invasive procedures decreasing the risk of fatal outcomes.
ABSTRACT
Objectives: Duodenal perforation as a complication of endoscopic ultrasound-guided fine needle aspiration may progress to acute peritonitis and septic shock. Open surgery, the standard treatment, can be avoided by performing closure during endoscopy using endoscopic clips.Patient: A 77-year-old woman was referred to our hospital with salivary gland swelling. She had elevated hepatobiliary enzymes and jaundice. Computed tomography (CT) revealed pancreatic head swelling and bile duct dilation. Endoscopic ultrasonography revealed a hypoechoic mass in the pancreatic head. The pancreatic head mass was punctured twice using a 22-gauge Franchine-type puncture needle at the duodenal bulb. The endoscope was advanced to the descending part of the duodenum, and part of the superior duodenal angle was perforated (diameter approximately 15 mm) with the endoscope. The duodenal mucosa around the perforation was immediately closed using endoscopic clips.Results: Abdominal CT showed gas in the peritoneal and retroperitoneal spaces. The patient experienced abdominal pain and fever and was treated with fasting and antibiotics. The gas gradually decreased, symptoms improved, and she was discharged 18 days after the perforation. Histopathologically, the pancreatic tissue was consistent as autoimmune pancreatitis.Conclusion: Endoscopic closure using endoscopic clips may be a better therapeutic option for duodenal perforation caused by endoscopy.

ABSTRACT
Endoscopic retrograde cholangiopancreatography (ERCP)-related perforations of the duodenum are rare but serious complications. Some ERCP-related perforations can be successfully managed without surgery. However, the presence of duodenal perforation may lead to premature termination of the ERCP and need for additional procedure such as percutaneous biliary drainage. If the ERCP-related perforation is identified early during the procedure, primary closure of the perforation can be attempted first or after completion of ERCP. We report two cases of duodenal perforation during ERCP in which ERCP was successfully completed after primary closure of the perforation.

Objective: To evaluate the benefit of radiotherapy planning, involving the use of surgical clips in conservative treatment of earlystage breast cancer. Methods: Retrospective cohort. Twelve (12) breast cancer female patients were retrospectively evaluated. These women had undergone breast-conserving treatment in which the tumor bed had been demarcated with titanium 200 surgical clips to guide breast boost radiotherapy. Volumes were calculated. Radiotherapy planning in the same patient with boost dose guided by metal clips was compared to planning guided by surgical scar or by imaging tests prior to surgical treatment. Results: A reduction of 36.7% in total volume of the irradiated breast (p=0.022), a reduction of 55.7% in boost volume (p=0.001), a reduction of 35.9% (p=0.001) in the breast volume receiving the prescribed boost dose and a reduction of 4.5% (p=0.014) in the maximum dose applied to the lung were shown. Conclusions: Clip placement in surgical bed following conservative treatment for breast cancer determined a reduction of 36.7% in irradiated breast volume and use of a lower dose of irradiation.
Objetivo: Avaliar o benefício do planejamento radioterápico, envolvendo o uso de clipes cirúrgicos em tratamento conservador de estágio inicial de câncer de mama. Métodos: coorte retrospectiva. Doze (12) pacientes do sexo feminino com câncer de mama foram avaliadas retrospectivamente. Estas mulheres foram submetidas a tratamento conservador da mama em que o leito do tumor foi demarcado com grampos cirúrgicos de titânio 200 para orientar a radioterapia de mama. Os volumes foram calculados. O planejamento de radioterapia no mesmo paciente com dose de reforço guiada por clipes metálicos foi comparado ao planejamento guiado por cicatriz cirúrgica ou por exames de imagem antes do tratamento cirúrgico. Resultados: Foram observadas uma redução de 36,7% no volume total da mama irradiada (p = 0,022), uma redução de 55,7% no volume do reforço (p = 0,001), uma redução de 35,9% (p = 0,001) no volume mamário recebendo a dose de reforço prescrita e uma redução de 4,5% (p = 0,014) na dose máxima aplicada ao pulmão. Conclusões: A colocação do clipe no leito cirúrgico após tratamento conservador para câncer de mama determinou uma redução de 36,7% no volume mamário irradiado e o uso de menor dose de irradiação
ABSTRACT
Resumen: El tratamiento de aneurismas intracraneanos rotos y no rotos incluye opciones quirúrgicas (clips vasculares) y endovasculares. Existen varios dispositivos y técnicas de manejo endovascular (coils, stents, diversores de flujo), cuyo conocimiento permite elegir e interpretar adecuadamente las técnicas de imágenes para el seguimiento no invasivo. Mediante una revisión pictográfica del control de aneurismas intracraneanos tratados quirúrgicamente y vía endovascular, se muestran las diferencias en la capacidad de caracterización en el seguimiento con angio TC, angio RM sin contraste (con técnica de "tiempo de vuelo" o "TOF" por sus siglas en inglés), angio RM con gadolinio endovenoso (C+) y angiografía por sustracción digital (ASD). Adicionalmente se entregan recomendaciones para el seguimiento de aneurismas según modalidad y dispositivo de tratamiento.
Abstract: Treatment of intracranial ruptured and unruptured aneurysms can be performed with surgical (vascular clips) or endovascular procedures (coils, stents, flw diverters). There are several devices and techniques for endovascular treatment. Knowledge of this techniques allows physicians to choose and interpret accurately imaging modalities for non-invasive follow-up. Through a pictorial essay of imaging follow-up of treated intracranial aneurysms we show the differences in characterization with computed tomography angiography, magnetic resonance angiography without contrast (time of flght or "TOF" technique), contrast enhanced MR angiography (C+) and digital subtraction angiography (DSA). Additionally we recommend imaging modalities for each treatment device.

OBJECTIVE: Surgical clipping of the cerebral aenurysm is considered as a standard therapy with endovascular coil embolization. The surgical clipping is known to be superior to the endovascular coil embolization in terms of recurrent rate. However, a recurrent aneurysm which is initially treated by surgical clipping is difficult to handle. The purpose of this study was to research the management of the recurrent cerebral aneurysm after a surgical clipping and how to overcome them.METHODS: From January 1996 to December 2015, medical records and radiologic findings of 14 patients with recurrent aneurysm after surgical clipping were reviewed retrospectively. Detailed case-by-case analysis was performed based on preoperative, postoperative and follow-up radiologic examinations and operative findings. All clinical variables including age, sex, aneurysm size and location, type and number of applied clips, prognosis, and time to recurrence are evaluated. All patients are classified by causes of the recurrence. Possible risk factors that could contribute to those causes and overcoming ways are comprehensively discussed.RESULTS: All recurrent aneurysms after surgical clipping were 14 of 2364 (0.5%). Three cases were males and 11 cases were females. Mean age was 52.3. At first treatment, nine cases were ruptured aneurysms, four cases were unruptured aneurysms, and one case was unknown. Locations of recurrent aneurysm were determined; anterior communicating artery (A-com) (n=7), posterior communicating artery (P-com) (n=3), middle cerebral artery (n=2), anterior cerebral artery (n=1) and basilar artery (n=1). As treatment of the recurrence, 11 cases were treated by surgical clipping and three cases were treated by endovascular coil embolization. Three cases of all 14 cases occurred in a month after the initial treatment. Eleven cases occurred after a longer interval, and three of them occurred after 15 years. By analyzing radiographs and operative findings, several main causes of the recurrent cerebral aneurysm were found. One case was incomplete clipping, five cases were clip slippage, and eight cases were fragility of vessel wall near the clip edge.CONCLUSION: This study revealed main causes of the recurrent aneurysm and contributing risk factors to be controlled. To manage those risk factors and ultimately prevent the recurrent aneurysm, neurosurgeons have to be careful in the technical aspect during surgery for a complete clipping without a slippage. Even in a perfect surgery, an aneurysm may recur at the clip site due to a hemodynamic change over years. Therefore, all patients must be followed up by imaging for a long period of time.

Pseudocysts of pancreas is collection of fluid in the lesser sac enclosed by a wall of fibrous or granulation tissue as a consequence of acute pancreatitis, pancreatic trauma or chronic pancreatitis. Invasive drainage procedures are currently indicated in those patients with symptoms or complications. We present our experience of 26 cases of pseudocyst of pancreas managed laparoscopically between Nov-2014 to March-2016 using different techniques of anastomosis using Vicryl 2-0 continues sutures as well as using Titanium clips for creating stoma between anterior wall of pancreatic pseudocyst and posterior wall of stomach. Laparoscopic cysto-gastrostomy appears to be safe and effective approach for internal drainage of pancreatic pseudocyst. It also facilitates the debridement of the necrotic tissue from the cyst cavity. Use of Titanium clips can be an alternative to conventional sutured cystogastrostomy and stapled cystogastrostomy, as it is less time consuming, easy to perform and cost effective

Results The gastric tumors were complete successfully resected in the iffteen patients through endoscopic surgery, applied the purse-string sutures with titanium clips and endoloops after the EFTR when the gastric walls were perforated artiifcially. Approximately, ifve clips were utilized on average. Postoperative surgical wound healing was followed up for 6 months, no tumors recurred. Conclusion It is safe, minimally invasive treatment method for rapid rehabilitation in endoscopic full-thickness resection utilized purse-string sutures with titanium clips and endoloops.
ABSTRACT
Objective To analyze the displacement of titanium clips for tumor bed localization after breast-conserving surgery for breast cancer and its influential factors.Methods A retrospective analysis was performed on the cone-beam computed tomography (CT) images of 14 patients with breast cancer who received radiotherapy after breast-conserving surgery from April to October,2016.The relative position of the chest wall and the errors of the titanium clips in radiotherapy were measured.A Pearson correlation analysis was used to analyze the correlation of the displacement of titanium clips with the relative position of titanium clips,the breast volume,the vertical distance between the titanium clips and the tangential line of the chest wall,and the maximum thickness of the breast.Results The system errors of the chest wall in left-right,superior-inferior,and anterior-posterior directions were 4.42,3.44,and 5.13 mm,respectively,and the random errors were 3.55,3.07,and 4.54 mm,respectively.The titanium clips had a large displacement relative to the chest wall,mainly in the left-right direction.The maximum system error was 4.39 mm and the random error was 2.42 mm.The displacement of titanium clips was not significantly correlated with the breast volume and the maximum thickness of the breast (P>0.05).However,the relative position of titanium clips in superior-inferior direction was significantly correlated with the displacement of the lowest,the most lateral,the most anterior,and the most posterior titanium clips (P<0.05).As to the uppermost clips,there was a significant difference in displacement between the clips close to the chest wall and the clips far from the chest wall (P=0.02).Conclusions Due to large setup error and displacement of titanium clips during radiotherapy,simultaneous integrated boost is not suitable for patients with breast cancer who are immobilized by vacuum cushion and received radiotherapy.The unstable immobilization may be the major influential factor for the displacement of titanium clips.
ABSTRACT
Objective To evaluate the efficacy and safety of combined use of insulated-tip knife, titanium clips and transparent caps in the resection of large pedunculated colorectal polyps. Methods Therapeutic method: with the assistance of transparent cap, 1~3 titanium clip(s) were applied to the base of the stalk to block blood supply of large polyps and then insulated-tip knife was utilized to resect polyps by cutting the stalk. Research method: retrospectively analyze the clinical data of 45 large pedunculated colorectal polyps (head ≥ 2.0 cm) which were treated by the method mentioned above from January 2014 to December 2015. Statistics of procedure time, clip numbers, complication rates were used to assess the effect of the treatment. Results 45 large polyps were successfully removed one time without any severe complications of bleeding or perforation during procedure except a very small amount of blood were oozing from the cutting edge in 3 cases. There were also no delayed complications of bleeding or perforation after procedure. The average number of titanium clip was 2.7 and the average operating time was (5.7 ± 1.2) min (range 3 ~ 12 min). Conclusion Combined application of insulated-tip knife, titanium clips and transparent cap inthe resection of large pedunculated colorectal polyps is safe, effective and convenient to conduct.

Research method: retrospectively analyze the clinical data of 45 large pedunculated colorectal polyps (head ≥ 2.0 cm) which were treated by the method mentioned above from January 2014 to December 2015. Statistics of procedure time, clip numbers, complication rates were used to assess the effect of the treatment. Results 45 large polyps were successfully removed one time without any severe complications of bleeding or perforation during procedure except a very small amount of blood were oozing from the cutting edge in 3 cases. There were also no delayed complications of bleeding or perforation after procedure. The average number of titanium clip was 2.7 and the average operating time was (5.7 ± 1.2) min (range 3 ~ 12 min). Conclusion Combined application of insulated-tip knife, titanium clips and transparent cap inthe resection of large pedunculated colorectal polyps is safe, effective and convenient to conduct.
ABSTRACT
Postoperative complications from gastrointestinal surgery can be associated with significant morbidity, and mortality especially if repeat surgery is needed to address these complications. There are wide array of endoscopic interventions and tools available for management of these complications using minimally invasive methods thus decreasing length of hospitalization, morbidity and leading to better patient outcomes. With the advent new tools like Overstitch device, Over the Scope Clip, fibrin glue, etc., these complications can be managed successfully with minimal morbidity. We provide an indepth discussion about available endoscopic options and their application in various scenarios in our article. Endoscopist should be familiar with these complications and endoscopic tools to promote use of these tools and techniques to achieve successful management of these complex conditions.
