[Surgical training and inguinal hernia repair]. / L'enseignement de la chirurgie influence-t-il les résultats des cures de hernies de l'aine?

AIMS: To evaluate influence of surgical experience on inguinal hernia repair. PATIENTS: From 1997 to 2003, 380 patients (mean age 55 years old) with primary unilateral inguinal hernia were treated by Lichtenstein technique. METHODS: In this retrospective study, surgeons were classified in three groups: group 1: hernia repair was performed by an experimented surgeon (consultant or senior registrar) and a young surgical trainee (resident) (161 cases); group 2: surgery was performed by a junior surgeon (resident) under the control of an experimented surgeon (135 cases) and in the group 3 (84 cases), Lichtenstein technique was performed by two residents, alone, supervised by an experimented surgeon, in the operative room. Evaluation criterion were operative time, hospital stay, morbidity, time to return to normal and professional activities, recurrences and chronic pain with a follow up of, at least, 2 years. RESULTS: The three groups were comparable in term of socio economic data, hernia and follow up. The only significant (P=0.01) difference concern operative time which increased from 20% for group 2 and 3 (residents) compared to the group 1. There was also no difference between junior and senior resident. CONCLUSION: Lichtenstein hernia repair should be performed by young surgeon in training alone in condition of precise teaching organization and experimented surgeon supervision. For patient, in this condition, there is no trouble in term of surgical results.

[Is laparoscopic treatment of adhesions a valid approach for postoperative abdominal pain?]. / L'adhesiolyse laparoscopique est-elle licite dans les ventres opérés douloureux?

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]. / Incidence de l'apprentissage et de l'expérience sur la technique et les résultats du traitement laparoscopique de reflux gastro-oesophagien.

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.

[Impact of learning and experience on the laparoscopic treatment of gastroesophageal reflux]. / Influence de l'apprentissage et de l'expérience dans le traitement laparoscopique du reflux gastro-oesophagien.

STUDY AIM: Laparoscopic treatment of gastroesophageal reflux disease (GERD) by partial (PF) or total (TF) fundoplication is the most appropriate surgical treatment after failure of medical treatment. The aim of this study was to compare the results of the same series in three consecutive periods in order to determine the effects of the learning curve and experience on the technique and outcome. PATIENTS AND METHODS: From January 1993 to January 1998, 150 patients (84 men and 66 women) with a mean age of 52.2 years (18 to 78) were included. Three groups of 49, 50 and 51 patients were chronologically defined. The comparison was established on the following criteria: the operative technique; the conversion rate; the mortality and morbidity rate; the duration of surgery and hospitalization and the results with short and medium follow-up. RESULTS: The three groups were comparable with respect to patients and GERD characteristics. One hundred and thirty two patients had a TF and 18 had a PF. Rossetti'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 min). The rate of conversion 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%. Seven cases of recurrence occurred (4.6%), 5 in group I (10.2%), 2 in group II (4%), and 0 in group III, (with a shorter follow-up). CONCLUSION: The effect of the learning curve has to be taken into account in the training of surgeons (within experienced departments, with "guidance" during initial interventions) and also in the evaluation of results, in order to allow a more accurate comparison between the different treatments for GERD.
