“…Blood tests to determine the previously mentioned indices were scheduled to be performed the next morning. To estimate the depth of insertion, the insertion count method proposed by May et al was used [12,13]. In the EN-580T group, if the endoscopist found a lesion requiring endoscopic treatment, then therapeutic intervention was conducted at that time.…”

Background This study aimed to compare the markers of potential pancreatic injury during antegrade double-balloon endoscopy (DBE) using the newly developed ultrathin EN-580XP system and the conventional EN-580T system. Methods Patients who were scheduled for antegrade DBE during daily clinical practice were enrolled. Clinical background, adverse events, and laboratory data of patients were compared between those who underwent endoscopy using the EN-580XP system and those in whom the EN-580T system was used. The primary end points were pancreatic hyperamylasemia and hyperlipasemia after DBE. Results A total of 295 cases were registered. Pancreatic hyperamylasemia occurred in 2 of 92 patients (2.2 %) in the EN-580XP group and in 28 of 147 patients (19.1 %) in the EN-580 T diagnosis group (P < 0.001). Hyperlipasemia was significantly different between the two groups (1.1 % [EN-580XP] vs. 13.6 % [EN-580 T diagnosis]; P < 0.001). Acute pancreatitis occurred in four patients (7.1 %) in the EN-580 T therapy group. Multiple logistic regression analyses revealed that the endoscope type EN-580 T was significantly associated with pancreatic hyperamylasemia (adjusted odds ratio [OR] 8.63, 95 % confidence interval [CI] 1.97 – 37.70; P < 0.01) and hyperlipasemia (adjusted OR 13.10, 95 %CI 1.70 – 100.70; P = 0.01). Conclusions The EN-580XP system seemed less harmful to the pancreas during antegrade DBE.

“…Sampling sites in the human gastrointestinal system. Biopsies were sampled from two specific sites in duodenum (1, 2) and seven specific sites in the distal ileum (10) and in colon (11)(12)(13)(14)(15)(16). In the intermediate small intestine biopsies were sampled for every 30 cm and grouped into seven areas (3-9).…”

“…To better understanding the problem in the last decade we have carried out several of experiments in porcine model[ 32 - 39 ] where oral DBE were systematically monitored. Although the porcine model was previously used both ex vivo and in vivo for DBE training and to increase the security conditions in translational studies[ 2 , 35 , 36 ], no previous in vivo studies were directly aimed at finding out the etiology of the post-DBE pancreatitis. In the present work, we are summarizing our findings[ 33 , 34 , 39 ], with addition of some unpublished results, and reviewing the related literature in order to gather substantial evidences supporting the vascular etiology as the most likely explanation for the potential appearance of pancreatitis after oral DBE.…”

Double balloon enteroscopy (DBE) is an endoscopic technique broadly used to diagnose and treat small bowel diseases. Among the associated complications of the oral DBE, post-procedure pancreatitis has taken the most attention due to its gravity and the thought that it might be associated to the technique itself and anatomical features of the pancreas. However, as the etiology has not been clarified yet, this paper aims to review the published literature and adds new results from a porcine animal model. Biochemical markers, histological sections and the vascular perfusion of the pancreas were monitored in the pig during DBE practice. A reduced perfusion of the pancreas and bowel, the presence of defined hypoxic areas and disseminated necrotic zones were found in the pancreatic tissue of pigs. All these evidences contribute to support a vascular distress as the most likely etiology of the post-DBE pancreatitis.

Validity of insertion depth measurement in double-balloon endoscopy

Abstract: Measurement of insertion depth in vivo was validated in the porcine model during progression and withdrawal. Estimation during progression was more accurate and allowed exploration dynamics and efficiency to be plotted, which might be used as approximate reference values for humans.
