[Endoscopic (endoluminal) treatment of gastroesophageal reflux disease].

New endoscopic (endoluminal) methods have been developed recently for the treatment of gastroesophageal reflux disease. The options are endoluminal gastroplasty, delivery of radiofrequency to the lower oesophagus reducing transient relaxation of the lower sphincter, or implantation of polymer in the lower oesophagus. The respective results of these procedures are detailed and discussed. The lack of long term follow-up and the number of procedures do not allow to validate the endoluminal procedures which remain in the field of clinical research. When the medical treatment fails or in case of complication, the glod standard is still the laparoscopic fundoplication. But it is possible in the future that one or more endoluminal techniques could change the management of reflux disease.

[Evaluation of laparoscopic bariatric surgery using the BAROS score].

AIM OF THE STUDY: Mid-term assessment of laparoscopic adjustable silicon gastric banding (Lap-Band) by a specific score. PATIENTS AND METHODS: One hundred consecutive patients received by mail 12 to 54 months after laparoscopic adjustable gastric banding a questionnaire including the Bariatric Analysis and Reporting Outcome System (BAROS) which is the only specific and validated instrument for measuring the quality of life after bariatric surgery. This score includes five categories of results (failure, fair, good, very good, excellent). It uses three major fields: the quality of life, excess weight loss, and medical comorbidities evaluation. RESULTS: Seventy three patients answered back with a mean follow up of 24.6 +/- 10 months. Forty six (2/3) had lost more than 50% of their weight excess. Sixty six experienced an improvement of their medical conditions following surgery. Final results were good or excellent for 60 patients (82% of those who answered back). Failure was reported in 7 patients (2 "sweet eaters" and 2 pouch dilatations) which needed a surgical treatment. CONCLUSION: This evaluation based on the BAROS confirms its validation in France and the good mid-term results of bariatric surgery based on the Lap-Band.

[Relation between activity volume and surgeon's results: myth or reality?].

The relationship between volume and surgical outcome seems logical, but needs to be demonstrated in the real world. A qualitative systematic review has been conducted to verify this hypothesis. Five systematic reviews and hundred original papers have been retrieved and analysed. Most of the studies were retrospective and used administrative data instead of medical charts. Moreover few studies involved a good case mix adjustment when comparing surgical units or individual surgeons. These methodological flaws do not allow any evidence based conclusions. Even though a positive relationship is suggested for surgical units, the relationship between volume and outcome was however less obvious for an individual surgeon. There is some evidence that the relationship varied greatly according to the specialty or the procedure evaluated. A new approach based on predictive scores comparing expected versus observed outcomes is mandatory and seems to be the best way to assess objectively the relationship between surgical volume and outcomes.

[Dynamic graciloplasty in the treatment of severe fecal incontinence. French multicentric retrospective study].

UNLABELLED: The aim of this study was to retrospectively assess the safety and efficacy of dynamic graciloplasty performed in 5 French surgical centers involved in the treatment of fecal incontinence. PATIENTS AND METHODS: Between March 1994 and March 2000, a total of 24 patients were treated with dynamic graciloplasty for fecal incontinence excluding case of anal reconstruction for cancer. Intramuscular leads and neurostimulators were implanted to stimulate the transposed gracilis. Continence and safety were evaluated using patients' records during hospitalisation and during the out-patient visit or further hospitalisation. RESULTS: No death occurred. A successful functional outcome was reported for 19 patients (79%) during the follow up period. Twenty-two complications occurred including wound. Wound infection in 6 patients and tendon detachment in 4. One patient presented with an infected anal erosion leading to material explantation. CONCLUSION: Dynamic graciloplasty is an effective procedure for patients with refractory fecal incontinence. However, the procedure has significant morbidity which seems to be correlated with the surgeons' experience. Moreover, this procedure should now be compared to the artificial anal sphincter.

[Do bipolar scissors increase postoperative adhesions? An experimental double-blind randomized trial].

AIM: The use of bipolar scissors (PowerStar) which has been suggested to reduce bleeding during surgical dissection, involves the theoretical risk for increasing intraperitoneal adhesions because of burn damages to the peritoneum secondary to bipolar electrocautery. MATERIAL AND METHOD: Thirty-six white new-Zealand rabbits have been included in a double-blind randomised trial to undergo a laparotomy using either a sharp scissors with on-demand monopolar coagulation or a bipolar scissors. Operatives procedures were standardised: midline laparotomy (5 cm), mobilisation of the right colon, incision of the colonic serosa without suture, incision of the colonic serosa with running sutures, incision of the mesentery. All these steps were performed by the same device according to the randomisation. Ten days later, the rabbits were killed. Adhesions were measured and scored according to the Zühlke classification by a surgeon who was not aware of the type of scissors used. Finally a pathological examination of adhesion was randomly performed. RESULTS: The two groups were similar for weight and sex-ratio. Two rabbits died before the tenth postoperative day (1 unknown aetiology and 1 evisceration). 34 rabbits were available for the study (18 in the "PowerStar" group and 16 in the control group). The results showed no significant difference between the groups for all measured endpoints (length and score of intraperitoneal and parietal adhesions). Nevertheless, pathological examination showed the burn damages to be less pronounced after using PowerStar. CONCLUSION: Bipolar scissors do not increase postoperative adhesions in the rabbit and probably induce less burn damages than monopolar cautery. The additional advantage i.e. the decrease adhesions formation, because of a less intraperitoneal bleeding, has not been observed in this randomised trial.

[The suprahepatic approach. An easy laparoscopic access to the hiatus in obese patients].

The conventional laparoscopic access to the gastroesophageal junction involves the retraction the left hepatic lobe upward. This approach could be particularly difficult in obese patients because of a huge fatty liver. The technique described here aims to overcome this difficulty be using a suprahepatic route by displacing the left lobe downward after dividing the left triangular ligament. This approach allows a good exposure of the gastroesophageal junction to perform a fundoplication or a gastric banding.
