RESECTION OF DUODENAL WEB USING HYBRID NATURAL ORIFICE TRANSLUMINAL ENDOSCOPIC SURGERY (NOTES)

Contributors: Maria Carmen Mora, MD1

We performed an incisionless resection of the duodenal web via the existing gastrostomy site. Initially the plan was to use the endoscope for visualization and the gastrostomy site for instrumentation; however, the endoscope visualization was inadequate. The gastrostomy site was dilated and an extra small wound protector was placed with a sterile glove over it allowing insufflation and access via the fingers for the laparoscope and 3mm instruments. A 70-degree laparoscope was used for visualization. The opening of the web was cannulated using a Fogarthy catheter prolapsing the web towards the stomach. A 3mm hook cautery and then the LigaSure were used to incise and excise the anteriolateral aspect of the duodenal web. Intraoperative CXR ruled out free air. A 1cm 14-French Mickey button was placed at the completion of the procedure. The length of the operation was 100 minutes.

PA Catheter Removal

Many suggest that the catheter fragment is safe to leave in place. However, this is not universally true by any means and catheters do, on occasion, embolize to the pulmonary artery. This has obvious dangers but also makes retrieval more difficult and dangerous. Retrieving the fragment in the SVC is generally a straight-forward procedure for an interventional radiologist and does not leave a foreign body in the SVC.

OPERATIVE VIDEO: ANORECTAL MALFORMATION. RECTOPERINEAL FISTULA WITH VAGINAL AGENESIS

Contributors: Victoria A. Lane, MBChB

The video demonstrates the initial examination findings of a vestibular fistula, with a normal vaginal introitus, however on closer inspection the vagina was found to be atretic. Standard mobilization of the rectum was performed in the prone position, followed by a lower midline laparotomy in order to examine the internal gynecological structures. A uterus and cervix were identified, but there was agenesis of the distal vagina. The operative technique for rectal pullthrough and simultaneous vaginal replacement, completion of the neo-vaginoplasty, and anoplasty is shown in the operative video.

On Table Contrast Enema

On initial fluoroscopy, the transverse colon can usually be seen as it contains air. If the colon cannot be visualized, a water-soluble contrast enema can be performed by inserting a Foley catheter into the rectum and infusing contrast by gravity.

Manipulation of Wire Past Pylorus

Once the wire is in the stomach a 5Fr Kumpe catheter is placed over the wire and the catheter and the wire are manipulated past the pylorus and to the ligament of trietz. If the pylorus is difficult to locate air or contrast can be injected through the catheter to delineate the anatomy. This contrast/air injection can be done throughout the procedure to confirm anatomy and guide in the direction of the course of the bowel. Once the ligament of treitz is reached the wire is exchanged through the catheter for a stiff wire hydrophilic wire. The appropriate GJ tube is selected and placed over the wire into the jejunum. Both the wire and lumen of the tube should be very wet to ensure that friction does not cause problems in tube placement. Balloon should be inflated with diluted contrast (half and half) and pulled back to the anterior abdominal wall and grommet synched down appropriately. Contrast should be injected into the jejunal port and gastric port to confirm the tube is in the appropriate position
