[Comparison of laparoscopic ultrasound and cholangiography during laparoscopic cholecystectomies. Results of a prospective study].

AIM: Prospective evaluation of the results of laparoscopic ultrasound and cholangiography to investigate choledocholithiasis and detect variations in biliary anatomy during laparoscopic cholecystectomies. METHODS: The biliary trees of 600 patients who underwent laparoscopic cholecystectomy were routinely explored by laparoscopic ultrasound and cholangiography. RESULTS: Laparoscopic ultrasound was performed in all 600 cases. Cholangiography was performed in 498 (83%). Laparoscopic ultrasound required less time than cholangiography: 10.2 minutes versus 17.9 minutes (P=0.0001). Common bile duct stones were detected intraoperatively in 40 cases (7%). Both methods were equally effective. The sensitivity of laparoscopic ultrasound was 80% and its specificity 99%. For cholangiography these values were 75% and 98% respectively. For laparoscopic ultrasound, false positives and false negatives were noted in the first 45 cases of individual trainees. Nevertheless, cholangiography showed 30 anatomical anomalies and laparoscopic ultrasound only 15. CONCLUSION: Laparoscopic ultrasound can be performed rapidly and in all cases. Results are comparable to cholangiography in the detection of common duct stones. Individual training is necessary to optimize efficacy. Anatomical anomalies are often missed.

[Is laparoscopic treatment of adhesions a valid approach for postoperative abdominal pain?].

The role of post-operative adhesions in chronic abdominal pain remains controversial. The aim of this study was to assess the value of laparoscopic treatment of adhesions for chronic post-operative abdominal pain in 32 patients. Over a period of 8 years, 32 patients (25 women and 7 men) with a mean age of 41.5 years (18-69) were hospitalized for chronic abdominal pain of more than 6 months duration, without an obvious underlying neoplasm or psychiatric disorder. They had all undergone at least one previous abdominal operation (mean, 1.9; range, 1-5), with a mean follow-up of 28 months (6-82). The mean duration of the pain was 18 months (6-65) and in 24 of the 32 cases it was mainly hypogastric. Other than the presence of a scar, the clinical examination was completely normal. Prior to hospitalization, 163 different laboratory tests, 162 radiological investigations, including 13 CT scans and 3 MRIs, and 25 endoscopies had been performed. A pneumoperitoneum was made by "open laparoscopy" in 23 cases and with Verres needle in 9 cases. Eight patients (25%) did not have any adhesions, but 6 of them were found to have a gynecological problem (endometriosis). In this group, the laparoscopy lasted 34 minutes (15-45) and the mean hospital stay was 48 hours. In 24 cases, adhesions were found and selected. This was thought to be complete in 22 cases (91.6%). There was a strict correlation between the adhesions and the scar in 85% of cases. In 5 cases, the adhesions were associated with another intervention. There were no conversions. The mean duration of surgery and hospitalization was respectively 56 minutes (32-120) and 3.2 days. There was no mortality and the morbidity rate was 4.1% (1 monopolar injury). The average follow-up was 26.7 months: 22 of the 24 patients who had freeing of adhesions were evaluated after at least 6 months of follow-up. In 10 cases, the pain had completely resolved (45%), in 6 it had decreased (27%) and in 6 cases it was unchanged or had even worsened (1 case of endometriosis). Laparoscopic exploration for chronic post-operative abdominal pain, after an extensive work-up performed after a suitably long delay post-surgery, can be used to detect and treat adhesions in 3/4 cases. In the absence of another lesion, the pain is lessened in 72% cases. However, if there is another lesion, laparoscopic treatment of adhesions is less effective with respect to the pain, but it nevertheless can identify an.

[The effect of the learning curve and the experience on the technique and the outcome of laparoscopic treatment for gastroesophageal reflux].

The laparoscopic treatment for gastroesophageal reflux disease (GERD) by partial (PF) or total (TF) fundoplication is the current surgical treatment of choice after failure of appropriate medical treatment. The overall results with fundoplication include the initial learning period during which the rate of complications, and failures are assumed to be greater. The aim of this study was to compare the results of laparoscopic treatment for GR in 3 groups of consecutive patients in order to determine the effect of the learning period and the experience on the technique and the outcome. One hundred and fifty patients (84 men and 66 women) with an average age of 52.2 years (18 to 78) were included. Surgery was indicated for failure or early relapse following the end of medical treatment. The preoperative work-up (endoscopy, barium meal or oesophageal pH monitoring) was governed by the clinical picture. The choice between TF and PF was based on the results of pH monitoring. Three groups of 50 patients around were chronologically defined. The parameters that were examined were: the operative technique; the conversion rate; the mortality and morbidity rate; the duration of surgery and hospitalization and the results at short and medium term follow-up. The three groups were comparable with respect to patient characteristics and the nature of their GERD. All patients had an endoscopy, 91% a barium meal, 77.5% underwent esophageal manometry and 67% pH monitoring. One hundred and thirty two patients had a TF and 18 had a PF. Rosetti's type TF became the reference procedure (80.3% in group III) and closure of the diaphragmatic crura was performed systematically in group III (100%). The duration of surgery was significantly reduced between group I and the two other groups (138, 100, 80 mn.). The rate of conversion, due to a variety of causes, decreased from 10.2% to 4% and then 0%. The average duration of hospitalization decreased from 5.8 to 4.2 days (p = 0.01). There was no mortality and the morbidity rate decreased from 14.3% to 4% and then 0%. There was 7 cases of relapse (4.6%), 5 in group 1 (10.2%) and 2 in group II (4%), with no cases in group III although the follow-up is shorter. There is an effect of the learning curve on the outcome of treatment for GR and this must be taken into account in the training of surgeons (training within experienced departments and "guidance" during their initial interventions) and also in publications in order to allow a more accurate comparison of the different treatments for GERD.

[Laparoscopic treatment of acute cholecystitis. Incidence of anatomo-clinical variations (271 cases)].

The study is based on 1050 laparoscopic cholecystectomies for gallstones performed between 1991-1999, out of which 271 were preoperatively considered as acute cholecystitis (25.8%). The clinical, biological and ultrasound criteria were rigorously respected. The preoperative period of 1 to 5 days (mean--2.5) was used for re-equilibration and antibiotic and antithrombotic therapy. The intraoperative criteria were clinical, echolaparoscopical, cholangiographical and bacteriological and established in 219 cases the diagnostic of acute cholecystitis. The final diagnostic, on histopathological basis, confirmed the preoperative diagnosis of acute cholecystitis in 224 cases. The microscopical reexamination in the remainding controversy cases reclassified other 18 as acute cholecystitis (final concordance ratio--242:271). The preoperative overvaluation may be consecutive to a too rapid (before the constitution of specific lesions) or too delayed intervention (the aspect becoming chronical). The elements of diagnostic discordance are raising the problem of case selection and the necessity for standard classification of histological lesions in acute cholecystitis.

[Use of prosthesis in inguinal hernia repair].

AIMS: To evaluate the use of mesh in the evolution of hernia repair technique during a period of twelve years. PATIENTS--METHODS: From january 1991, to december 2002, 1306 patients 1136 men, 190 women, with inguinal hernia, with a mean age of 47.4 years old (15-98) have had an elective surgical repair. 1097 (83.9 per cent) were unilateral. 209 (16.1 per cent) were recurrent hernia. Clinical data, operative technique have been prospectively evaluated: Four techniques were used: Shouldice procedure, Stoppa operation and laparoscopic repair (TEP) in 1992 and Lichtenstein technique since 1993. RESULTS: During the study, meshes were used in 65.7 per cent of the patients respectively 33.3 per cent for Lichtenstein, 26.9 per cent for laparoscopic repair and only 5.3 per cent for Stoppa open procedure. During the study, prosthesis rate increased from 9.1 to 85.4 per cent for primary hernia and from 10 to 100 per cent for recurrent hernias. To day, Stoppa procedure is not yet performed. Herniorraphies decrease from 91.9 to 14.6 per cent. CONCLUSIONS: "Tension free" techniques represent 85.4 per cent of all procedures at the end of the study, specially Lichtenstein operation (65 per cent) which seems to become the new "Gold Standart" in inguinal hernia repair.
