Vacuum sponge therapy using the pull-through technique via a percutaneous endoscopic gastrostomy to treat iatrogenic duodenal perforation.

In 2011, a 37-year old patient with a history of familial adenomatous polyposis underwent a subtotal colectomy and resection of the proximal jejunum and distal duodenum with side-to-side duodenojejunostomy. The procedure was performed for adenocarcinoma of the duodenum (pT3 pN0 L0 V0 R0 G2). In November of 2013, an endoscopically irresectable recurrent adenoma of the anastomosis was seen. Surgical resection was also impossible because of desmoids of the mesentery. Therefore, it was decided intraoperatively to resect the adenoma endoscopically in piecemeal fashion. Histology again showed adenocarcinoma (pT1 R2), and the residual carcinoma was treated at intervals of 6 months with argon plasma coagulation (APC). In June of 2015, the patient developed fever and abdominal pain 24 hours after the last APC therapy. Computed tomography showed free fluid and air adjacent to the ablation site (●" Fig.1a). Endoscopy confirmed a duodenal perforation (●" Fig.2a). Because of a lack of surgical options, an Eso-Sponge (B. Braun Melsungen AG, Melsungen, Germany) was placed close to the perforation. However, post-interventional computed tomography showed that the Eso-Sponge had dislocated to the stomach (●" Fig.1b). The risk for persistent dislocation was minimized as follows: First, with a Pexact Device II (Fresenius Kabi AG, Bad Homburg, Germany), the anterior gastric wall was sutured (four polydioxanone [PDS] sutures) before a conventional 20-Fr percutaneous endoscopic gastrostomy (PEG) catheter (Fresenius Kabi AG) was inserted using the pull-through technique. This procedureminimizes the risk for peritonitis during frequent manipulations. A thread was introduced through the PEG into the stomach and drawn out orally with a grasping forceps. The thread was connected to the end of the Eso-Sponge tube. Second, the Eso-Sponge device was introduced into the stomach using the pull-through technique, and the EsoSponge tube was diverted through the PEG. Third, intraluminally the Eso-Sponge was positioned endoscopically close to the duodenal perforation (●" Fig.3a, ●" Fig.3b). A negative pressure was applied (30mmHg). The Eso-Sponge was changed three times (at 4to 6-day intervals) as follows: A gastric tube was connected to the external end of the Eso-Sponge tube. The EsoSponge was grasped in the duodenum, drawn out orally, and cut off. The end of a new Eso-Sponge tube was connected to the end of the transoral tube. Finally, the sponge was drawn into the stomach by the pull-through technique under endoscopic view, as described previously, and then repositioned in the duodenum. The patient received total parenteral nutrition and antibiotic treatment (cefuroxime/metronidazole) for 10 days. Because of various risk factors (obesity, sleep apnea, lockjaw), all procedures were performed with the patient under general anesthesia. No further sponge dislocation occurred. At 20 days after the initiation of treatment, the cavity appeared closed (●" Fig.2b), and the patient was started on solid food. The PEG was removed 7 days later. Endoscopic vacuum therapy has been established as an effective treatment for perforations [1,2]; however, it must be frequently modified in the upper gastrointestinal tract [3–5], and clinical experience is still limited. As shown in this case, intraluminal vacuum therapy is a feasible treatment option for a duodenal perforation. Because of the long distance and several angles bridged by the sponge tube and adherence to the endoscope during retrieval of the device, there is a high risk for dislocation of the sponge when it is placed in the duodenum intraluminally and drawn out nasally. Use of the pull-through technique via PEG for sponge placement and necessary changes during treatment reduces the intraluminal distance of the Eso-Sponge Fig.1 a Duodenal perforation with free intra-abdominal fluid and air (arrow) in a patient undergoing argon plasma coagulation treatment for recurrent adenocarcinoma. b The inserted sponge (arrow) had dislocated to the stomach at 24 hours after endoscopic placement in the duodenum in order to treat the perforation shown in a.
