Incision of the bladder neck for a small prostate

On Tuesday May 29th at 3:00pm EDT, University Hospitals Case Medical Center Cleveland, Ohio, will host a live webcast to demonstrate the removal of brain tumor and epileptic focus from an awake patient using intra-operative MRI and brain mapping. See this on OR-Live.com

The patient was a middle-aged gentleman with new onset seizures. An MRI showed what appeared to be a low grade glioma near the motor strip on the right. Studies have shown that complete removal can cure the seizures, improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because its difficult to determine where tumor ends and normal brain begins.

ENDOSCOPIC (NON-SURGICAL) REMOVAL OF MULTIPLE LARGE TUMORS FROM STOMACH IN A PATIENT WITH PEUTZ-JEGHERS SYNDROME
PEUTZ-JEGHERS SYNDROME: Peutz-Jeghers syndrome (PJS) is a familial syndrome consisting of mucocutaneous pigmentation, gastrointestinal polyposis and cancers of gut & other sites like breast, ovary, and testes. PJS has an autosomal dominant inheritance with variable and incomplete penetrance. Germline mutations of STK11/LKB1 gene on 19p cause this syndrome. Mucocutaneous pigmentation may be noted in early infancy. These deposits of melanin are most commonly found around the mouth, nose, lips, buccal mucosa, hands, and feet, and may also be present in perianal and genital areas. PJS polyps may be found in stomach, small intestine, or colon, but they tend to be prominent in the small intestine. These polyps may increase in size and cause small intestinal obstruction or intussusceptions that may occur in early infancy. Acute upper gastrointestinal bleeding and chronic faecal blood may complicate the disease.
PATIENT: The patient was a 25 yr male who had mucocutaneous pigmentation and multiple polyps in the stomach and duodenum. He presented with bleeding from gastric polyps. As the polyps in stomach were numerous, (more than 20 in number) and were large in size (some equal to small egg size), he had been advised to undergo surgery. Surgery planned was total gastrectomy.
PROCEDURE: The patient underwent video-endoscopy of the esophagus, stomach and duodenum. All polyps were examined for size and presence or absence of stalk. A plan to remove all the gastric polyps at endoscopy was made in the same sitting. He received light conscious sedation. Flat polyps were raised form the gastric wall by injection of saline in to polyp base to let these lesions have a stalk. This was done by needle injector. Each polyp was engaged in a snare and the polyp stalk was cut by coagulation cutting current. The cuts were clean without any bleeding. All polyps were recovered for histology. The histology revealed all polyps to be hamartomous lesions. None of the polyps were cancerous. Patient has been followed up for over one year and is doing fine without any further bleeding or pain.
Video shows the procedure of videoendoscpy and endoscopic removal of polyps.

Maintaining sufficient blood flow to the gastric tube after a subtotal esophagectomy for esophageal cancer is crucial for decreasing the esophagogastric anastomotic leakage. After subtotal esophagectomy for esophageal cancer, to additionally revascularize the gastric tube using the splenic artery a...nd vein, external carotid artery, and internal jugular vein, the supercharge technique was performed in esophageal reconstruction patients. Operative results of these patients (supercharge group) were retrospectively compared with those of patients not receiving the technique (control group). Both operation time and operative blood loss in the supercharge group were significantly longer and larger than those of the control group. However, the incidence of anastomotic leakage was significantly lower in the supercharge group than in the control group, and a 30-day reduction in the mean postoperative hospital stay was achieved with the supercharge group. This practical supercharge technique could be a breakthrough less to reduce leakage during esophageal anastomosis.

The colonoscope is slowly withdrawn during this screening colonoscopy down from the transverse colon, back around the splenic flexure, and down the descending colon, and reveals this finding a colonic diverticula. Diverticulosis is a common, acquired, age-related occurrence affecting over 50% of the... western adult population over the age of 50. It is seen rarely in Africa and Asia where the dietary fiber content is traditionally higher. Thus most investigators feel that low fiber diets are related to the development of this condition. Ironically, colonic diverticula are not true diverticula but rather pseudodiverticula in that the sac includes layers of the mucosa and submucosa that push through rather than include the outer muscular layer. As with the small bowel the colon has an inner circular muscular layer, but the outer longitudinal layer is composed of three bands of muscle that run the length of the colon known as teniae. Diverticula occur in rows between the mesenteric and two antimesenteric teniae where the colonic wall is further weakened by the defect caused by the perforating vasa recti artery which supplies the colonic mucosa. Occasionally, the anatomic propensity of diverticula to form in rows is quite apparent as seen when this clip is replayed in slow motion. Most often, however, the arrangement of the diverticula appears random due to the angulation of the bowel and thickening of the semi lunar folds. The conditions that cause these pulsion diverticula are not know with certainty but may include high intrahaustral pressures, muscular hypertrophy, and age related alterations in collagen cross linking. Diverticula can bleed or can abscess and perforate. The incidence of diverticulitis or diverticular bleeding is in the range of 1:1,000 patients with diverticulosis.

Pancreatic pseudocyst drainage was the first therapeutic application of EUS. The cyst is punctured under ultrasound guidance, contrast injected, and a guidewire inserted. Initial dilation to 8mm is performed over the wire The EUS scope is then exchanged over the wire for a forward viewing endoscope.... A second dilation to 18mm is performed. This enables entry of the endoscope into the cyst perform cystoscopy, debridement if necessary, and insertion of multiple large bore double pigtail stents. The curved linear array-or CLA—echoendoscope has oblique viewing optics located proximal to an oblique scanning transducer. The accessory exits from the shaft of the echoendoscope at an ablique angle, adjustable between 15 and 30 degrees. There are several technical limitations using this echoendoscope. The oblique angle of exit results in a weekend transfer of force when advancing the accessory, difficult deployment of larger bore accessories, and in instrument tunneling effect relative to the bowel wall. There is the potential loss of access during endoscope exchange. A novel CLA echoendoscope was developed by the Olympus Corporation that shifts the orientation of endoscopic and ultrasound views from oblique to forward viewing. The channel is therapeutic at 3.7mm Note that the working channel is located adjacent to the ultrasound transducer at the endoscope tip. The accessory exits the working channel in the axis of the shaft. Shown here are balloon inflation and deployment of a Dormia basket. We report on the use of the prototype forward viewing echoendoscope in six consecutive patients who were referred for pancreatic cyst drainage. Here you see endoscopic view-indistinguisable from that of a gastroscope-showing a bulge where the cyst impinges against the posterior gastric wall. Power Doppler is switched on and highlights multiple vessels interposed in the wall This allows selection of a safe vessel-free window for a cyst puncture A 19 G needle is advanced into the cyst lumen. A sample of contents is aspirated for fluid analysis. A guidewire under ultrasound guidance into the cyst. An 18mm balloon is coaxially thread over the wire and advanced across the cyst wall, Note that resistance is encountered, but the forward transfer of force overcome this. The dilation is performed under forward viewing endoscopuc and ultrasound guidance. As the balloon is maximally inflated we see the cystgastrostomy open up. The balloon is then deflated while simultaneously advancing the scope into the cyst cavity. Cystoscopy isnow performed showing the cyst contents to be filled with pasty wall-adherent necroses. Pulsed power Doppler is switched on we can see and hear arterial flow vessels within the wall of the cyst. This identifies sensitive areas at bleeding risk when performing debridement In this case vigorous water jet irrigation is performed through an accessory water irrigation channel built into the echoendoscope. This issued to clear nonadherent debris. Our experience has shown that it is not necessary to actively remove wall-adherent debris using extraction tools as such Dormia or Roth net basket to achieve cyst resolution. Three large bore 10 Fr double pigtail stents are now inserted into the cyst under direct endoscopic guidance. The first stent is delivered over a guide catheter. The second stent. And the third stent All three stents are deployed. Finally, a nasocystic catheter is inserted for maintenance irrigation. In another patient we used the Cook Cystome to perform cystgastrostomy. We have found the Cystotome easy to delivery through the forward viewing echoendoscope. As shown, we advance the Cystotome into the cyst while applying diathermy. This is performed under and endoscopic guidance, entering the cyst at a near perpendicular orientation. After entry, the Cystotome is removed and cyst fluid gushes from the cystagastrotomy site.
