The loop-forming method as a useful technique to rotate the endoscopic insertion tube shaft.

ABSTRACT: Gastroenterological endoscopists are instructed to bring the target to the 6-o'clock position when they take a biopsy specimen, use a snare, or cut a target organ. This action is performed primarily by rotating the shaft of the endoscopic insertion tube, which can be difficult in some situations when existing endoscopic methods are used. We previously described a method for optimal rotation of the endoscopic insertion tube shaft, called the loop-forming method (LFM). The present study aimed to validate this procedure and confirm the usefulness of the LFM for leftward rotation of the shaft.The LFM was specifically taught to 28 gastroenterological endoscopists, and the angle of rotation was measured before and after they received instruction in this method.The LFM significantly increased the average angle of leftward rotation from 266° to 327°. Moreover, whereas the instrument channel inlet tended to move away from the right hand of an operator using a conventional endoscopy method, it remained closely accessible to the right hand of an examiner using the LFM.The LFM has the potential to make endoscopic procedures easier and safer.

Transhepatic Insertion of Percutaneous Endoscopic Gastrostomy Tube.

Project description:Inadvertent injury to interposing organs during percutaneous endoscopic gastrostomy (PEG) tube placement is a feared complication of this common and generally safe procedure. Transhepatic PEG insertion is likely an underrepresented complication which may be identified incidentally on imaging or present with life-threatening conditions such as sepsis or massive bleeding. Use of ultrasound in patients with known hepatomegaly may possibly help avoid this complication. We hereby report a case of transhepatic PEG insertion, one of 16 only other cases published in the literature, and review the characteristics of the previous reported cases.

New insertion method of transnasal ileus tube for small bowel obstruction: Anterior balloon method.

Project description:BackgroundSmall bowel obstruction (SBO) is usually caused by postoperative adhesions and malignant disease, and decompression is effective for SBO. Our previous case report suggested that a new transnasal ileus tube insertion method, the anterior balloon method (ABM), could achieve decompression for adhesive SBO.AimsThe study aimed to investigate the effectiveness of a new method for inserting transnasal ileus tubes in patients with SBO.MethodsAltogether, 134 patients with small bowel obstruction treated from January 2011 to December 2017 were reviewed. The patients were categorized into two groups: those with the new method that inserts an anterior balloon (ABM group: 52 patients, 2014-2017) versus those with the ordinary insertion method (OIM group: 82 patients, 2011-2014).ResultsThe patients' characteristics and symptoms on admission were similar in the ABM and OIM groups. Adhesions were the main cause of ileus in the two groups. The insertion time duration was significantly shorter in the ABM group than in OIM group (28.4 ± 9.1 vs. 33.5 ± 13.0 min; p = 0.01). The ABM group also had significantly longer tubes than OIM group (222.4 ± 32.2 vs. 157.4 ± 31.7 cm; p < 0.001), which resulted in a significantly shorter time until clinical symptoms were relieved in ABM group. There were no significant differences in adverse events between the two groups.ConclusionsThe ABM group had shorter insertion duration and longer tubes than those of OIM group. The ABM might become a preferred therapeutic choice to achieve decompression in patients with SBO.

Autologous Scleral Pocket Technique for Ahmed Glaucoma Valve Implantation with Pars Plana Tube Insertion for Neovascular Glaucoma.

Project description:Specific postoperative complications, such as tube exposure and conjunctival erosion, have occurred despite the favorable surgical outcomes of tube shunt surgeries for refractory glaucoma. The new autologous scleral pocket technique is performed by inserting the tube into the vitreous cavity without using a donor scleral patch. The purpose of this study was to evaluate the surgical results of Ahmed glaucoma valve (AGV) implantation using this technique for neovascular glaucoma (NVG), which is one of the representative refractory types of glaucoma. This observational retrospective case series included 15 consecutive eyes of 15 patients with NVG who had undergone AGV implantation at Kobe University between January 2018 and December 2019. The mean preoperative intraocular pressure (IOP) was 37.2 ± 13.8 mmHg and the glaucoma drug score was 4.2 ± 2.2. The mean IOP and glaucoma drug score at 1 year postoperatively decreased to 15.0 ± 4.6 mmHg and 1.3 ± 2.0, respectively (p < 0.001). No significant change in the corneal endothelial cell density following surgery was observed (p = 0.09); however, one patient required an additional trabeculectomy at 7 months postoperatively. No cases of tube exposure or conjunctival erosion were observed at 1 year postoperatively. These results indicated the effectiveness and safety of this technique in patients with NVG.

Relationship of early acute complications and insertion site in push method percutaneous endoscopic gastrostomy.

Project description:Percutaneous endoscopic gastrostomy (PEG), which is frequently used for nutrition management in patients having difficulty with oral intake, is considered a safe procedure. However, serious complications may occur depending on site of the puncture. This study aimed to clarify whether push method PEG construction at the posterior wall (PW) of the greater curvature (GC) had a higher risk of complications. We retrospectively investigated the relationship between puncture site at the PW of the GC and early acute complications in 540 patients receiving PEG. Early acute complications were defined as bleeding or perforation within 30 days after the PEG procedure. PEG-related complications were observed in 80 patients in total, with early acute complications detected in 42 patients. PEG construction at the PW of the GC in 12 cases exhibited a significantly higher occurrence of early acute complications versus PEG at other sites (41.7% vs. 7.0%, p = 0.001). Further, multivariate analysis revealed PW at the GC to be independently associated with early acute complications (OR 9.59, 95% CI 2.82-32.61; p = 0.0003). It may be desirable to avoid PEG at the PW of the GC. If performed, clinicians should pay careful attention to early acute complications.

Reamed compared with unreamed nailing of tibial shaft fractures: Does the initial method of nail insertion influence outcome in patients requiring reoperations?

Project description:BackgroundPatients with a tibial shaft fracture experiencing their first postoperative complication following treatment with intramedullary nails may be at greater risk of subsequent complications than the whole population. We aimed to determine whether the initial method of nail insertion influences outcome in patients with a tibial shaft fracture requiring multiple reoperations.MethodsUsing the Study to Prospectively Evaluate Reamed Intramedullary Nails in Tibial Shaft Fractures trial data, we categorized patients as those not requiring reoperation, those requiring a single reoperation and those requiring multiple reoperations, and we compared them by nail insertion technique (reamed v. unreamed) and fracture type (open v. closed). We then determined the number of patients whose first reoperation was in response to infection, and we compared other clinical outcomes between the reamed and unreamed groups.ResultsAmong 1226 patients included in this analysis, 175 (14.27%) experienced a single reoperation and 44 patients (3.59%) underwent multiple reoperations. Nail insertion techniques (reamed v. unreamed) did not play a role in the need to perform multiple reoperations. Seventy-five percent of patients requiring multiple reoperations had open tibial shaft fractures. An equal number of these were reamed and unreamed insertions. The majority of patients had their course complicated by infection and almost 50% of patients whose first reoperation was for infection required more than 2 reoperations for management. The rest required multiple procedures for nonunion or bone loss.ConclusionOur findings corroborate those of other studies, in which open fracture type rather than nail insertion technique was found to be the cause of morbidity following intramedullary nailing of tibial fractures.Clinical trial registrationwww.Clinicaltrialsgov, no. NCT00038129.
