Management of spontaneous and iatrogenic perforations, leaks and fistulae of the upper gastrointestinal tract

The Contribution of a Collagen Patch Coated With Fibrin Glue in Sealing Upper Gastrointestinal Defects: An Experimental Study

BACKGROUND/AIM

We aimed to evaluate the safety and efficacy of sealing primary upper gastrointestinal (GI) perforations with a collagen patch coated with fibrin glue (Tachosil^®).

MATERIALS AND METHODS

Thirty New Zealand rabbits were used in this study. An iatrogenic gastric perforation was created, and primary repair was performed on the control group. Tachosil^®, without suturing the deficit, was used in the intervention group.

RESULTS

Leakage was observed in 3 (20%) and 2 rabbits (13.3%) in the control and intervention group, respectively; however, the difference was not statistically significant (p=0.62). Moreover, adhesions formed in 10/15 and all rabbits in the intervention and control group, respectively (p=0.014); however, based on the Zuhlke adhesion's classification, there was no statistically significant difference between the two groups.

CONCLUSION

A collagen patch coated with fibrin glue is not a replacement but can be considered a safe option for the reinforcement of suturing, preventing leakages in the upper GI tract.

Gastric conduit perforation after Ivor Lewis esophagectomy successfully treated with endoscopic vacuum therapy (E-VAC): a case report

Gastric conduit perforation is a life-threatening complication after esophagectomy and currently there is no consensus about its optimal management. Endoscopic vacuum therapy (E-VAC) is a promising technique for the treatment of leaks and perforations after upper gastro-intestinal surgery. We report the case of a 65 years-old male patient who underwent an Ivor Lewis esophagectomy for esophago-gastric junction adenocarcinoma. He referred to our Emergency Department for septic shock and right hydropneumothorax. We performed an emergency thoracoscopy with intraoperative esophagogastroduodenoscopy which showed a pre-pyloric perforation of the gastric conduit. The perforation was initially treated with unsuccessful primary surgical closure and subsequently by means of E-VAC, firstly placed intraluminal and then intracavitary. With the latter technique, we assisted to a progressive clinical improvement until the definitive healing of the perforation. To our knowledge, this is the first case of a gastric tube perforation after esophagectomy successfully treated with E-VAC.
