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
Objective@#To evaluate the feasibility and short-term efficacy of a novel and simplified closure method developed by our team for the defect closure after endoscopic full-thickness resection (EFTR) for gastric submucosal tumors (SMT) in the gastric wall.@*Methods@#A prospective single-arm clinical study was used. Inclusion criteria: (1) the lesion was located in the fundus or the greater curvature of the stomach, and was confirmed to originate from the muscularis propria layer; (2) the diameter of the tumor was ≤3.5 cm, and the tumor had no extensive adhesion to the peritoneal tissues and organs in extraperitoneal cavity; (3) the tumor had no malignant features under ultrasound endoscopy; (4) the patient agreed to participate in the study; (5) patients with severe complications were excluded. Based on the above criteria, 20 patients with gastric SMT at the Endoscopy Center of Zhongshan Hospital of Fudan University from January 2015 to March 2018 were enrolled in this study, including 5 males and 15 females with mean age of 61.1 (38 to 70) years. Grasping forceps-assisted endo-loop snare ligation device which is called "Shao-Mai" method was used to close the defect site. All the patients underwent EFTR and "Shao-Mai" method to perform defect closure. After successful tumor resection by EFTR, an endo-loop was anchored onto the edge of the gastric defect with grasping forceps assistance and closed tightly. The observation indicators included tumor size, en bloc resection, operation time, postoperative complications and hospital stay. The follow-up indicators included tumor residual, local recurrence, and metachronous lesions.@*Results@#All the 20 lesions were located in the muscularis propria with a size of 0.5-3.5 (mean 1.4) cm. Three of them were located in the greater curvature of the mid-upper gastric body, 17 were located in the fundus. The endoscopic "Shao-Mai" closure was successfully performed after EFTR in all the 20 cases. Endoscope was used uniquely through the entire process, without laparoscopic assistance. The operative time was 20-100 (mean 43.8) minutes, while the "Shao-Mai" closure procedure took a range of 3-30 (mean 10.1) minutes. The en bloc resection rate was 100%. The pathological diagnosis included 17 gastrointestinal stromal tumors and 3 leiomyomas. No major complications occurred during or after surgery. All the patients were discharged 1-11 (mean 3.1) days after operation. The wounds of all the cases were healed completely six months after operation and only scar was observed without ulcer. No residual lesion, tumor recurrence or metastasis, leakage or fistula of digestive tract were found during the follow-up period of 15-54 (median 41) months.@*Conclusion@#The endoscopic "Shao-Mai" closure method is a simplified novel way, which is feasible, effective, and safe for closing the gastric defect after EFTR.
ABSTRACT
SUMMARY OF EVENT: A 2 cm-sized colonic perforation occurred during diagnostic colonoscopy. Endoscopic closure was performed immediately using detachable snare and conservative management with intravenous antibiotics was followed for several days. However, abdominal computed tomography showed huge abscess and its connection to the sigmoid colon. The patient underwent segmental colectomy, which revealed the incomplete closure of perforated lesion with severe serosal fibrotic change. TEACHING POINT: Endoscopic treatment of large-sized colonic perforations should be undertaken with caution since the possibility of incomplete closure is high. For large-sized colonic perforations, early surgical treatment should be preferentially considered over endoscopic treatment.

Objective To evaluate the feasibility and the safety of endoscopic closure for acute colon perforations with novel successive endoclips in animal model. Methods Approximately 1. 5 to 2 cm colonic full-thickness resections were created with an electrotome in 3 Ba-Ma pigs that were under general anesthesia and were closed with the conventional endoclips and novel successive endoclips respectively. The procedure time and the efficacy of each endoclip were recorded. After the procedure,the general condition and physiological indicators were carefully monitored. After a follow-up of 1 week,the pigs were euthanized for an endoscopic observation of the healing condition and the residual endoclips. A postmortem examination was performed to observe the abdominal infection and incision condition. Transverse sections of the colon across the site of perforation were taken for histopathologic examination to assess the healing process. Results All the colonic perforation models in three pigs were established successfully. Endoscopic closure for acute colon perforation with two kinds of endoclips was technically successful in all 3 pigs. The mean time of the procedure with successive endoclip was less than that with the conventional endoclip(54. 0 seconds VS 91. 9 seconds,P<0. 001),but the successful release rate of the successive endoclip was lower than that of the conventional endoclip without significant difference[62. 5%(15/ 24)VS 14/ 16,P= 0. 17].All the ani-mals survived without infection and hemorrhage. Five perforations demonstrated signs of healing,whereas one closed with the novel successive endoclips failed to heal completely. Conclusion Endoscopic closure for a-cute colon perforations with novel successive endoclips is effective and safe. The novel successive endoclip has the advantage of saving time,but it needs to be further improved and perfected to satisfy the clinical need.
ABSTRACT
Full-thickness gastrointestinal defects such as perforation, anastomotic leak, and fistula are severe conditions caused by various types of pathologies. They are more likely to require intensive care and a long hospital stay and have high rates of morbidity and mortality. After intentional full-thickness opening of hollow organs for natural orifice transluminal endoscopic surgery, safe and secure closure is urgently required. The currently available advanced endoscopic closing techniques have a major role in the treatment of full-thickness gastrointestinal defects. Appropriate usage of these techniques requires taking into account their advantages and limitations during practical application. We reviewed the available endoscopic modalities, including endoscopic clips, stents, vacuum-assisted closure, gap filling, and suturing devices, discussed their advantages and limitations when treating full-thickness gastrointestinal defects, and explored emerging innovations, including a novel endoluminal surgical platform for versatile suturing and a cell-laden scaffold for effective gap filling. Although these emerging technologies still require further pre-clinical and clinical trials to assess their feasibility and efficacy, the available modalities may be replaced and refined by these new techniques in the near future.

The management strategy for endoscopic retrograde cholangiopancreatography-related duodenal perforation can be determined based on the site and extent of injury, the patient's condition, and time to diagnosis. Most cases of perivaterian or bile duct perforation can be managed with a biliary stent or nasobiliary drainage. Duodenal wall perforations had been treated with immediate surgical repair. However, with the development of endoscopic devices and techniques, endoscopic closure has been reported to be a safe and effective treatment that uses through-the-scope clips, ligation band, fibrin glue, endoclips and endoloops, an over-the-scope clipping device, suturing devices, covering luminal stents, and open-pore film drainage. Endoscopic therapy could be instituted in selected patients in whom perforation was identified early or during the procedure. Early diagnosis, proper conservative management, and effective endoscopic closure are required for favorable outcomes of non-surgical management. If endoscopic treatment fails, or in the cases of clinical deterioration, prompt surgical management should be considered.
