Fibrin sealant for closure of mucosal penetration at the oesophagus or cardia during submucosal tunnelling endoscopic resection for gastrointestinal submucosal tumours

BACKGROUND AND STUDY AIM

To assess the efficacy and safety of a fibrin sealant for the prevention of leak resulting from mucosal penetration at the esophagus or cardia during a STER procedure to remove gastrointestinal submucosal tumors (SMTs).

PATIENTS AND METHODS

Between April 2014 and October 2022, a total of 290 patients with oesophageal or cardiac SMTs underwent STER at our centre. We retrospectively identified patients with oesophageal or cardia SMTs who underwent STER and experienced mucosal penetration of the cardia or oesophagus during the procedure. A total of 31 mucosal penetrations in 30 procedures were included. Of the 31 mucosal penetrations, 12 occurred in the cardia, and the other 19 occurred in the oesophagus. All 31 sites received the fibrin sealant to close the mucosal penetration. Clinical characteristics, procedure-related parameters, detailed data of the mucosal penetrations, and treatment outcomes using the fibrin sealant were reviewed for all 30 patients to assess the efficacy and safety of the fibrin sealant for closure of mucosal penetration at the cardia or oesophagus.

RESULTS

For the 31 mucosal penetrations, the mean size was 0.08 ± 0.06 cm2 (range 0.01-0.25 cm2). Mucosal closure using the fibrin sealant was performed successfully in all 31 mucosal penetrations. Of the 31 mucosal penetrations, clips were used in 13 cases. All 30 patients were discharged after a median of 7 days (range 4-20 day) postoperatively. During a mean 62 months (range 6-107 months) follow-up, all 31 mucosal penetrations successfully healed without the occurrence of infection, ulcer, oesophagitis, chest infection or abdominal infection.

CONCLUSION

For the closure of mucosal penetration during STER at the cardia or oesophagus, a fibrin sealant is both safe and efficacious. It is necessary to conduct more research on the viability, effectiveness, and safety of using a fibrin sealant to close wider mucosal penetrations.

Endoscopic tissue shielding with polyglycolic acid sheet, fibrin glue, and endoclip for perforation during balloon dilation for esophageal stricture after endoscopic submucosal dissection

Esophageal endoscopic submucosal dissection can cause esophageal strictures. Endoscopic balloon dilation is the standard treatment for esophageal strictures, but has complications, including perforation, and sometimes requires surgery. We report a case of perforation during endoscopic balloon dilation for esophageal stricture secondary to esophageal submucosal dissection that was successfully treated conservatively. A 66-year-old man with superficial carcinoma in the upper thoracic esophagus underwent circumferential endoscopic submucosal dissection with local steroid injections. Endoscopic balloon dilation was performed weekly for esophageal stricture. However, during the sixth procedure, an attempt to increase the size of the balloon to 13.5 mm resulted in perforation. The patient was treated conservatively using polyglycolic acid sheet with fibrin glue at the perforation site, which was fixed using an endoclip. However, the esophageal stricture persisted after the perforation was closed and Endoscopic balloon dilation was carefully repeated twice weekly up to a maximum of 17 mm, and the endoscope was able to pass through, and associated symptoms improved. This report indicates that endoscopic tissue shielding using polyglycolic acid sheet with fibrin glue and endoclip to correct perforation, followed by additional endoscopic balloon dilation, is an alternative to surgery.

The Effect of TISSEELTM on Confined Bowel Perforation: An Experimental Study

OBJECTIVE

During the last decades, surgeons of several specialties presenting different levels of expertise in colon handling have been involved in laparoscopic procedures. The aim of the present experimental study was to investigate the feasibility of TISSEELTM versus the conventional suture placement technique on confined bowel lesions in rats.

METHODS

Twenty-four Sprague-Dawley rats underwent confined bowel perforation and were divided into three groups: the SUTURE group (sutures were used), the SUTURE + TISSEELTM group (sutures and TISSEELTM were utilized), and the TISSEELTM group (only TISSEELTM was used). Blinded histopathologic analysis followed animal sacrifice.

RESULTS

The median weight of the rats was 526 ± 50 g. A single animal had hematochezia on the first postoperative day. Cessation of bleeding at the perforation margin was indicated intraoperatively after TISSEELTM application. Animals in the TISSEELTM group presented less intraperitoneal adhesions and lower hemorrhagic infiltration compared to animals of the two other groups. In addition, animals in the TISSEELTM group showed thrombus formation at the bowel perforation site compared to animals of the two other groups (p = 0.042). Histopathologic analysis demonstrated reduced inflammatory reaction (p = 0.003), diminished fibrosis (p = 0.001), and better tissue regeneration (p = 0.000) in the TISSEELTM group compared to the other two groups.

CONCLUSION

Application of TISSEELTM at the perforation site was associated with increased regeneration of the intestinal wall and less inflammatory and fibrotic reaction compared to suture placement. However, more experimental and clinical studies should be conducted before implementation in humans.

Perinephric urinoma, an unusual upper tract presentation of a lower tract injury following retroperitoneoscopy: A case report

BACKGROUND

A 66-year-old lady was referred to urology for a suspected urinoma after retroperioneoscopy done for debridement of a retroperitoneal abscess that developed following a duodenal perforation.

CASE SUMMARY

Serous contents of the drain sent for fluid creatinine were elevated confirming this and computed tomography urography findings suggested an upper tract injury with urinoma around the kidney. However, the antegrade nephrostogram suggested otherwise and on flexible cystoscopy and cystogram, an extraperitoneal bladder perforation was instead identified, with tip of retroperitoneal drain sitting inside the bladder.

CONCLUSION

This case identifies a limitation in the usual diagnostic approach for such injuries and emphasizes the need to exercise caution when managing them especially when they occur after several surgical procedures and in the presence of multiple surgical drains.

Fibrin sealants as an adequate treatment alternative to traditional suturing for confined bowel lesions: A hypothesis for future experimental research

Bowel perforation is a rare, but serious complication of laparoscopic surgery with a mortality rate that reaches 20%. There are several risk factors that could predispose to bowel perforation, but the surgeon's experience and the difficulty of each case play the most important role. Delayed bowel injuries happen due to conduction of electrical energy through the abdominal cavity, and in the majority of cases require reoperation. Early bowel injuries are caused by thermal injury of an electrosurgical instrument or during the insertion of the laparoscopic instruments inside the peritoneal cavity. Such injuries are recognized during the operation and are usually fixed by placing sutures. TISSEEL™ is a fibrin sealant with various applications in several surgical specialties, that simulates the latter stages of the coagulation cascade, and could be used as an alternative treatment for confined bowel perforations during laparoscopy. The efficacy of fibrin sealants in closing bowel gaps has been tested in some experimental models as well as its adequacy in enhancing bowel anastomoses performed with sutures. In addition, there is scarce evidence that fibrin sealants enhance the healing process after bowel enclosure either combined to suturing or not, which is supported by an experimental pilot study, that was conducted by our study group. The present study tries to combine all the available data in order to propose an effective alternative treatment for confined bowel injuries or controversial cases, that happen during laparoscopic surgery. In that way, every surgeon could face them even without huge expertise, conversions to open surgery would diminish and the disadvantages of suturing would disappear. Future experimental studies should be designed in the terms of extensive comparison of the two methods, with the purpose of this comparison to be tested in humans in the future.

Endoscopic shielding using oxidized regenerated cellulose after argon plasma coagulation under mandatory dual antiplatelet therapy

Endoscopic shielding is an innovative concept in therapeutic endoscopy. Its usage has been mostly restricted to wide‐field endoscopic mucosal resection and/or endoscopic submucosal dissection. A novel potential clinical use may be in bleeding pophylaxis for argon plasma coagulation‐related ulcers under concomitant mandatory dual antiplatelet therapy.

Efficacy and safety of endoscopic submucosal dissection for non-ampullary duodenal polyps: A systematic review and meta-analysis

BACKGROUND AND AIMS

Endoscopic submucosal dissection (ESD) is commonly used to treat early-stage digestive cancer because it results in a higher frequency of en-bloc resection and a lower frequency of local recurrence. However, the efficacy and safety of duodenal ESD remain unclear. Therefore, present study is aimed at evaluating clinical outcomes of duodenal ESD.

METHODS

To evaluate the efficacy and safety of duodenal ESD, electronic databases (MEDLINE, CENTRAL and EMBASE) were searched by two independent reviewers. The authors were contacted for additional information. A meta-analysis was performed to evaluate the efficacy and safety of duodenal ESD.

RESULTS

A total of 7 studies (203 patients) were included in the quantitative synthesis analysis. The pooled proportions of the frequencies of en-bloc resection, need for surgical intervention, bleeding, intraoperative perforation and delayed perforation were 87%, 4%, 2%, 15% and 2%, respectively. The quality of evidence regarding on surgical intervention outcomes was rated as moderate, whereas that of en-bloc resection was rated as low because of its marked inconsistency.

CONCLUSIONS

Duodenal ESD produced acceptable outcomes in terms of the en-bloc R0 resection, but the incidence of procedure-related adverse events is high (PROSPERO register, CRD42017057110).

Endoscopic plombage with polyglycolic acid sheets and fibrin glue for gastrointestinal fistulas

BACKGROUND AND STUDY AIMS

Gastrointestinal (GI) fistulas arise as adverse events of GI surgery and endoscopic treatment as well as secondary to underlying diseases, such as ulceration and pancreatitis. Until a decade ago, they were mainly treated surgically or conservatively. Bioabsorbable polyglycolic acid (PGA) sheets and fibrin glue, which are commonly used in surgical procedures, have also recently been used in endoscopic procedures for the closure of GI defects. However, there have only been few case reports about successful experiences with this approach. There have not been any case-series studies investigating the strengths and weaknesses of such PGA sheet-based treatment. In this study, we evaluated the clinical effectiveness of using PGA sheets to close GI fistulas.

PATIENTS AND METHODS

Cases in which patients underwent endoscopic filling with PGA sheets and fibrin glue for GI fistulas at Kobe University Hospital between January 2013 and April 2018 were retrospectively reviewed.

RESULTS

A total of 10 cases were enrolled. They included fistulas due to leakage after GI surgery, aortoesophageal/bronchoesophageal fistulas caused by chemoradiotherapy, or severe acute pancreatitis. The fistulas were successfully closed in 7 cases (70%). The unsuccessful cases involved a fistula due to leakage after surgical esophagectomy and bronchoesophageal fistulas due to chemoradiotherapy or severe acute pancreatitis. Unsuccessful treatment was related to fistula epithelization.

CONCLUSION

Endoscopic plombage with PGA sheets and fibrin glue could be a promising therapeutic option for GI fistulas.

Successful treatment of an esophageal perforation that occurred during endoscopic submucosal dissection for esophageal cancer using polyglycolic acid sheets and fibrin glue

A 74-year-old female, who was diagnosed with superficial esophageal cancer, underwent endoscopic submucosal dissection (ESD) at another hospital, but a perforation occurred during the procedure. The perforation was closed with endoscopic clips, and the ESD was halted. The patient was referred to our hospital, and ESD was retried. There was severe fibrosis around the lesion, and injections into the submucosal layer were difficult. In addition, it was not possible to identify the submucosal layer, and making an oral-side incision caused a large perforation along the incision line. As continuing the submucosal dissection with an endoknife was considered difficult, the lesion was finally resected with hybrid ESD using a snare. The perforation was closed using polyglycolic acid (PGA) sheets and fibrin glue. Endoscopy performed 6 days later showed that the defect had been closed, and no contrast leakage was detected. Follow-up endoscopy conducted 3 months after the ESD showed ulcer healing at the dissection site and scar formation, but no residual tumor or esophageal stricture was noted. Our experience suggests that the use of PGA sheets with fibrin glue is a feasible, safe, and effective way of treating large esophageal perforations during ESD.
