Laparoscopic Sugiura procedure for conditioning of the blood stream through TIPSS in cirrhotic patient. Initial experience.

The Sugiura procedure or the proximal gastric devascularisation was formerly the method of choice for esophageal varicose treatment in some patients. The frequency of this operation decreased stenting after the introduction of the transjugular portosystemic shunt into clinical practice. However this method performed laparoscopically could be useful as a complementary procedure when the blood stream through the transjugular intrahepatic portosystemic stent shunt is low and an esophageal rebleeding occurs. A 40-year old patient with hepatic cirrhosis and Child stage "B" was admitted to our clinic due to recurrent esophageal varicose bleeding. He underwent a transjugular intrahepatic portosystemic stent shunt implantation 27 months before the admission and the transjugular intrahepatic portosystemic stent shunt became occluded 3 times since implantation and was repeatedly revised. After admission a color Doppler of the stent was performed. The blood stream was 15 cm/s. The laparoscopic Sugiura procedure was performed after conditioning of the general status of the patient. Five ports were introduced 5 cm above the umbilicus, under the xiphoid, the right and left hypochondrium as well as the left mesogastrium. The dilated veins between the gastric coronary vein and esophagus and the short gastric veins on the great curvature were interrupted by means of an ultrasonic scalpel. The hiatus esophagus was opened, the esophagus was prepared up to the first pulmonal vein and the dilated esophageal veins were occluded with stitch ligatures. The operation was completed with Toupet partial fundoplication. The patient was followed 6 months after the surgery. No rebleeding occurred in this time period. Immediately after surgery the blood flow increased up to 97 cm/s; at 3 and 6 months follow-up the intrahepatic shunt remained open with 82 and 80 cm/s blood flow respectively. Laparoscopic Sugiura procedure performed as a complementary surgery after transjugular intrahepatic portosystemic stent shunt implantation increased blood perfusion through the intrahepatal constructed shunt and prevented its occlusion. However this initial experience has to be confirmed with a larger number of patients.

Closure of the cystic duct during laparoscopic cholecystectomy with a new feedback-controlled bipolar sealing system in case of biliary obstruction--an experimental study in pigs.

BACKGROUND/AIMS: The excellent results of new devices like the new bipolar feedback-controlled sealing system (LigaSure) for closure of blood vessels encouraged surgeons to use these instruments for other structures like bile ducts. The aim of this study was to evaluate the feasibility of closure of cystic duct in case of biliary obstruction. METHODOLOGY: Ten domestic pigs underwent laparoscopic cholecystectomy sealing the cystic duct with LigaSure. The common bile duct was closed with an endoclip to create a biliary hypertension. On the 12th postoperative day blood samples were taken for liver enzymes. At autopsy on day 15 the pigs were investigated for bile leaks or biliary peritonitis. The cystic duct was resected for histological examination. RESULTS: Seven pigs survived, one pig died during introduction of anesthesia, one on the 1st and one on the 2nd postoperative day without any findings at the autopsy. One pig out of 7 had a bile leak; the other 6 were without any sign of leakage. Histologically 3 pigs had a regular coagulation zone at the cystic duct, 3 had a total necrosis, one a partial necrosis of the mucosa only. CONCLUSIONS: Though there was only one insufficiency, the feedback-controlled bipolar vessel sealer cannot be recommended for biliary surgery with regard to the high rate of necrosis stated in our experiment.

The "balanced" operation for life threatening complications of severe "non responding" form of gastroesophageal reflux disease. A case report.

The fate of patients developing life-threatening complications of the Barret's non-responding ulcer during an acute treatment is lacking in the literature. Medical therapy with proton pump inhibitors (PPI) for severe forms of gastroesophageal reflux disease fails in 15-20%. Emergency operation is indicated in failed cases. We present an operation which restores anatomical and functional deviations causing reflux disease. Two patients required early surgery due to bleeding and penetration of Barret's ulcer during PPI therapy. Both patients had reflux disease, a Savary Miller stage of IV, and/or the M3; U1; S0; E3 and M3; U3; S0; E3 stage of "MUSE" assessment respectively. The modified "balanced operation" was performed consisting of a truncal vagotomy, hiatus hernia reposition, posterior crura repair, fundoplication and extramucosal pyloroplasty. Both patients had excellent outcomes after surgery. Visick I and II, or M3; U0; S0; E1 and M3; U0; S0; E0 respectively and remained well over the year without any medication. The modified "balanced" operation seems to be the method of choice for treatment of severe, "non responding" form of GERD when complications occur. Various pathophysiological factors such as hyperacidity, the cardia valve and gastric emptying are affected simultaneously. The rationale for the performance of all steps of the "balanced" operation is based on the fact that we do not know before the operation, which steps will be necessary to produce a good result.

Anterior luxtasphincteric stapled rectumresection.

BACKGROUND/AIMS: Sphincter saving deep anterior rectumresection improved the live quality of the rectal cancer patients. With the technical progress the resection level could be moved significant distally. The initial experiences are referred with the use of the stapler with flexible shaft in six patients operated due to very deep rectal cancer. METHODOLOGY: After the usual rectum mobilization the Proximate access AX55 mm (Ethicon) is positioned onto the stretched rectum. The flexible shaft has to be curved to the front and the jaw has to be angled parallel to the handle. The partially closed jaw of the stapler is then pushed towards the anus and then fired. The rectum is the resected. The operation is completed with EEA stapled anastomosis. RESULTS: Excellent results in all six patients could be noticed 3-18 months after the procedure. No cancer recurrence occurred. Functional sphincter investigation was performed in two patients with result of physiologic sphincter function. Stolen frequency has been stabilised between 2-8 a day. CONCLUSION: Improved transabdominal stapled method of rectum resection guarantees comfortable and oncologically safe resection of the distal rectum with maintenance of the sphincter function.

Laparoscopic transgastric pancreatic pseudocystogastrostomy--first experience with extraluminal approach.

BACKGROUND/AIMS: Transgastric cystogastrostomy (Jurasz procedure) became a standard procedure in the treatment of mature pancreatic pseudocysts contacting the stomach. The first experience with laparoscopically performed transgastric cystogastrostomy under performing anterior gastrostomy is discussed. METHODOLOGY: Five ports were used. The anterior stomach wall was opened 2 cm in length. The communication channel with the pseudocyst was created by means of precise coagulation of the posterior stomach as well as the pseudocyst wall. The pseudocyst was evacuated and the stoma was completed by stapling with the EndoGIA lineal stapler 3 cm in length. The anterior stomach wall was also closed with EndoGIA stapler. RESULTS: Excellent results could be achieved. The pseudocyst resoluted within 1 month after the operation, and the anastomosis healed completely. The patient was discharged on the 8th post-operative day. The follow-up for 1 year was free of complications. CONCLUSIONS: Laparoscopic pseudocystogastrostomy appears to be a reliable method for treatment of large size mature pancreas pseudocysts because it is a minimally invasive procedure with standardized stapler-performed anastomosis. However, this initial experience has to be confirmed with a large number of patients.
