Electrochemically deposited Pd islands on an organic surface: the presence of Coulomb blockade in STM I(V) curves at room temperature.

Palladium islands with a thickness of a few monolayers were deposited on top of a self-assembled monolayer (SAM) fabricated from 4-mercaptopyridine. In the I(V) curves obtained using the scanning tunneling microscope (STM) clearly the signature of Coulomb blockade is observed, explicitly demonstrating that these islands are coupled to the underlying gold substrate only via a tunneling barrier; this spectroscopic feature also allows to distinguish the palladium islands from similar morphological features present on the gold substrate prior to palladium deposition.

[Combined laparoscopic and endoscopic treatment of gallbladder and bile duct stones].

UNLABELLED: In the present study we have tried to find what is the best time for endoscopy in the treatment of gallstones associated with common bile duct stones. METHOD: We have selected on the intention to treat 89 patients suspected of cholecysto-choledocholithiasis. There have been 38 cases with preoperative endoscopy (Group A), 35 cases with postoperative endoscopy (Group B) and 16 cases with perioperative endoscopy (Group C). RESULTS: In group C it has been a significant higher proportion of successfully treated cases (94%) and a lower hospital stay (8.6 +/- 3.7 days). CONCLUSIONS: Combining the endoscopy and laparoscopy in the same operation ("rendez-vous" technique) is the best approach for treating cholecysto-choledocholithiasis.

[Is there a learning curve for laparoscopic cholecystectomy ?].

UNLABELLED: The use of laparoscopic surgery it is growing rapidly in Romania. We have tried to find if a learning curve for laparoscopic cholecystectomy exists and we have evaluated our training program to insure the quality of health care. METHODS: There where analyzed 2585 procedures performed by 22 surgeons. The relationship between operative incidents/accidents and laparoscopic experience was evaluated. With a regression model we have find the tendency of these relationship. RESULTS: Surgeons appear to learn this procedure rapidly. CONCLUSIONS: Training curses with hands-on experience with animal models and proctoring from an experienced laparoscopist at the first 30 operations is needed, for each individual surgeon, to insure the quality of health care.

[Transperitoneal laparoscopic right sympathectomy].

Laparoscopic lumbar transperitoneal sympathectomy represents the miniinvasive approach of laterocolic procedure Adson-Diez. It is suitable to laparoscopic surgery, has a good reproducibility and it is more advantageous than total retroperitoneal approach because of a larger working space.

[The laparoscopic approach to cholecysto-choledocholithiasis.The "rendez-vous " technique].

A combined method of endoscopic sphincterotomy (ES) with common bile duct (CBD) stone extraction and laparoscopic cholecystectomy under general anesthesia for a single-session treatment of patients with colecysto-choledocholithiasis is described. The so called "rendez-vous" technique consists in: standard laparoscopic cholecystectomy with intraoperative cholangiography followed by ES if common bile duct stones are detected. The sphincterotome is driven across the papilla through a wire guide inserted by transcystic route. Nine patients were scheduled for "rendez-vous" approach. At intraoperative cholangiography 4 have had CBD stones. Endoscopic sphincterotomy and CBD clearance were successful in all patients. No complication was encountered. Mean postoperative hospital stay was 5 days. The laparo-endoscopic "rendez-vous" approach is feasible, it reduces the number of unnecessary ERCP examinations, it lowers the morbidity related with endoscopic sphincterotomy and shortens the hospital stay.

[Minimally invasive approach in gallstone disease complicated with acute pancreatitis].

We have evaluated the minimally invasive approaches (laparoscopy, endoscopy) in the management of the gallstone disease complicated with acute pancreatitis. Hypothesis. Emergency ERCP in gallstone pancreatitis (GSP) associated with jaundice or angiocholitis has a beneficial effect on pancreatic inflammation, eventually favoring laparoscopic cholecystectomy. We have compared 18 cases of emergency ERCP for GSP associated with jaundice or angiocholitis (Group 1) with 72 cases of GSP where ERCP was indicated on a selective basis (Group 2). Laparoscopic cholecystectomy was done after the acute bout of pancreatitis subsided. The minimally invasive approaches were completed in 89% cases in Group1 and in 90% cases in Group 2, respectively. Pancreatic morbidity was better in Group 1 (0% vs. 15.2%), but without statistical significance. General morbidity was significantly lower (0% vs. 23.6%) as well as the mean hospital stay (13 +/- 5.5 days vs. 17 +/- 10.4 days). Only the lower general morbidity and the shorter hospital stay assert the hypothesis that emergency ERCP in GSP associated with jaundice or angiocholitis has a beneficial effect on pancreatic inflammation, eventually favoring laparoscopic cholecystectomy.

[Laparoscopic appendectomy--considerations in about 1000 cases].

Laparoscopic appendectomy (LA) is a well spread method today, but not as largely accepted as cholecystectomy, the cure of gastro-esophageal reflux and some other procedures (relatively small in number) for which the laparoscopic approach is the golden standard. Otherwise it is improbable that LA will gain such a status, at least in the near future. On the other hand it is obvious that LA offers important advantages for some special situations: the right iliac area syndrome, obesity, professional sportsmen, abnormal localization of the appendix, as well for the cases when localized and especially diffuse peritonitis is associated. Our paper analyses the experience of General Surgery Department at the "St.John" Emergency Hospital Bucharest on laparoscopic appendectomy. The retrospective study includes 996 cases that were treated laparoscopic between 1996-2004. Of these 745 cases were catarrhal, 166 cases were phlegmonous and 76 gangrenous appendicitis. In 93 cases localized or diffuse peritonitis was associated. There were recorded also 3 cases of each of the following: chronic appendicitis, appendicular mass and mucocele. The number of conversions was 28 (2.81%). There were also 10 reinterventions (1.004%), 7 because of intraperitoneal abscess and we also recorded one death.

[Laparoscopic treatment of transhiatal gastric hernia].

The paper is referring to the laparoscopic cure of the gastric transhiatal hernia. The first part is a short comment on the way to establish the need for surgery and to choose the adequate procedure. Then the main tactical aspects of the laparoscopic Nissen fundoplication are discussed. Finally the technique of the operation is detailed. Six patients were operated on with good results.

[Preliminary data on our laparoscopy experience in urinary pathology].

We studied laparoscopic urological procedures in 14 cases between July 1995 and October 1996. We applied retroperitoneal lomboscopic technique for 2 cases with symptomatic renal cyst (over 500 ml) and laparoscopic retroperitoneal lymphadenectomy in 12 cases (adenocarcinoma of the prostate-5 cases, pT2-3bMo, Gleason score between 3-9, PSA between 11-46 ng/ml and invasive bladder tumors-7 cases, pT2-3bMoG2-3). For the renal cyst we used extraperitoneal approach and for the pelvic lymph nodes we used in 8 cases intraperitoneal approach and in 4 cases extraperitoneal approach (patients with multiple prior abdominal surgeries). Lymph node tissue was present in 11 cases. For the bladder tumors we did first iliac lymph nodes dissection and for the prostate adenocarcinoma we did first obturator lymph nodes dissection. We didn't describe complications. For our patients it was 3 days long hospitalization. So, we consider that laparoscopic lymphadenectomy is essential for evaluation of the patients with prostate adenocarcinoma having markedly elevated prostate specific antigen, high Gleason grade, large clinical burden of tumor. For the invasive bladder tumors, radical cystectomy and especially bladder replacement surgery need absolutely evaluation of regional lymph nodes. For the symptomatic renal cysts (over 500 ml) laparoscopic surgery is with very good results, minimally invasive.

[A minimally invasive approach in choledocholithiasis].

In the last years several less aggressive procedures diminished the role of open choledochotomy (CT) in the treatment of common bile duct (CBD) lithiasis. Between them are endoscopic sphincterotomy (EST) and laparoscopic choledochotomy. In a lap of 18 month were followed up, in a prospective way, all the cases of CBD lithiasis admitted in our department. Twenty-seven patients were treated by EST and 28 by CT. The endoscopy was as efficient as open CT in clearing the CBD (85% vs. 83%). Even if the endoscopic group was at a higher risk the morbidity was lower than in the classic approach and the mortality was the same (3.5%). The most common complication after EST was acute pancreatitis (7.5%). The mean hospital stay was lower after EST. Near by are discussed 3 cases of associated gallbladder and CBD lithiasis treated exclusively by laparoscopic approach.

[Right laparoscopic lumbar sympathectomy].

Laparoscopic lumbar sympathectomy was performed on a young man with thromboangiitis obliterans (Buerger's disease). The surgeons disposition, trocars placement and dissection technique are described in detail. The retroperitoneal approach was done in a manner similar to laparoscopic properitoneal hernia repair. The operation can be carried out with common laparoscopic equipment (for cholecystectomy) and offers the benefits of minimally invasive surgery.

[Conversions and reinterventions in laparoscopic cholecystectomy].

From the introduction of the laparoscopy in our clinic, more and more of the cholecystectomies, reaching over 50% are done by this technique. Based upon the accumulation of an already important experience, the paper tries to analyze the situations in which, during or after laparoscopic cholecystectomy, intraoperative conversions (deliberate or of necessity) or reinterventions were necessary. We present a global view of the number of these cases and also (an in detail) analysis of the causes the imposed such decisions and of the solutions adopted. The percentages of 5.55 conversions and 1.49 reinterventions seem reasonable and acceptable in comparison with the initial results published by some experience surgeons in the field of laparoscopic surgery.
