[Laparoscopy under local anaesthesia and hypnoanaesthesia about 35 cholecystectomies and 15 inguinal hernia repair]. / Coeliochirurgie sous anesthésie locale et hypnosédation, à propos de 35 cholécystectomies et 15 cures de hernies.

OBJECTIVE: To present hypnosedation and the feasibility of this technique performed for laparoscopic procedure. STUDY DESIGN: Retrospective and descriptive study of feasibility. PATIENTS AND METHODS: Hypnosis can significantly reduce intraoperative requirements of intravenous sedation for surgery under local anaesthesia. Modifications of surgical procedure: laparoscopic surgery under local anaesthesia and hypnosis is performed using a subcutaneous lifting of anterior abdominal wall. Insufflation is only use to push out smoke. If patient or surgical uncomfort happens, moral contract with patient includes convert to general anaesthesia. RESULTS: We performed 35 cholecystectomies; 13 needed convert to general anaesthesia, mainly for peritoneal pain induced by CO(2) insufflation; 22 procedures were completed with patients' satisfaction. Upon 15-hernia repairs, only one patient needed convert to general anaesthesia, for dissection difficulty. CONCLUSION: Probably hypnosis can't be extent to intraperitoneal laparoscopic procedures. On the other hand interest of hypnosis performed for extraperitoneal laparoscopic hernia repair must be explore.

Early experience with laparoscopic approach for solid liver tumors: initial 16 cases.

OBJECTIVE: To evaluate the feasibility and outcome of laparoscopic hepatectomy in patients with solid liver tumors. SUMMARY BACKGROUND DATA: Although the laparoscopic approach has become popular in the surgical field, the value of laparoscopy in liver surgery is unknown. METHODS: Fifteen patients with solid liver tumors underwent 16 consecutive laparoscopic resections at the authors' institution between 1994 and 1999. Indications were symptomatic hemangioma, focal nodular hyperplasia, liver cell adenoma, isolated metastasis from a colon cancer, and hepatocellular carcinoma. The laparoscopic procedure was performed using four to seven ports (four 10-mm, two 5-mm, and one 12-mm). RESULTS: One patient underwent a major hepatic resection (right lobectomy); the others underwent minor hepatic resections (left lateral segmentectomies, IVb subsegmentectomies, segmentectomy, and nonanatomical excisions). The laparoscopic procedure was uneventful in 15 patients; one patient required conversion to open laparotomy because of inadequate free surgical margins. CONCLUSION: Laparoscopic surgery of the liver is feasible. The use of this new technical approach offers many advantages but requires extensive experience in hepatobiliary surgery and laparoscopic skills. The authors' experience suggests that laparoscopic procedures should be reserved for benign tumors in selected cases. Its application must be verified by further studies.

Laparoscopic fundoplication in children: our first 30 cases.

We report our experience performing 30 laparoscopic fundoplications in children (24 using the Nissen Rossetti technique and 6 using the Toupet fundoplication). Special instruments adapted to the young children are used: first, a miniature parietal suspender to decrease the intra-abdominal pressure and to provide more space; second, a retractable losenge-shaped liver retractor; and third, a Babcock forceps articulated at 60 degrees. In the Nissen Rossetti procedure, the wrap is fixed to the anterior face of the esophagus, the anterior wall of the fundus, and the upper right crus. In the Toupet procedure, the wrap is a retroesophageal partial fundoplication: the first suture attaches the wrap to the right crus, the second attaches the wrap to the esophagus, and the third recreates the oesogastric angle. We do not use gastrostomy. Patients have no gastric tube after the intervention. Thirty children from 2 to 15 years have undergone laparoscopic fundoplications. One conversion to open procedure was necessary. An average follow-up of 12 months was observed for 18 children with 3 complications: dysphagia for a psychotic girl, intrathoracic valve without any trouble, and recurrent episodes of digestive bleedings during 6 months. Laparoscopic fundoplication is a feasible extension of minimally invasive surgery in the hands of experienced surgeons; however limitations must be recognized to do a safe operation.

Extramucosal pyloromyotomy by laparoscopy.

Since 1990, we have performed extramucosal pyloromyotomies by laparoscopy in 70 infants presenting with congenital hypertrophic pyloric stenosis. Ever since the first cases, the technique and the instruments have been adapted. The surgical technique and the precautionary measures are here explained again. This technique is beneficial for infants with a better postoperative course and avoidance of any skin scar.

Hypertrophic pyloric stenosis is the commonest condition requiring abdominal surgery in infancy. The Fredet-Ramstedt pyloromyotomy gives a very rare morbidity rate as shown by a review of 300 personal cases. The diagnostic value of sonography is gaining significance over contrast roentgenography, a pyloric diameter of more than 14 mm and a muscular thickness of more than 4 mm being required for the diagnosis. Over the last 18 months, we performed extramucosal pyloromyotomies using laparoscopy in 19 infants. This new surgical technique using laparoscopy with precautionary measures for the pneumoperitoneum appears to be very promising and should become a widespread technique in the future.

Pyloromyotomy as described by Fredet and Ramstedt is still widely used for the treatment of infantile hypertrophic pyloric stenosis, with a very low mortality rate. Three hundred case-records of patients treated using this technique were reviewed. Pyloromyotomy can benefit from the use of videosurgical methods. The creation of a pneumoperitoneum requires special precautions in infants. Nineteen infants were treated using laparoscopic Fredet-Ramstedt pyloromyotomy, a technique which can be expected to gain widespread acceptance during the next few years.

Extramucosal pylorotomy by laparoscopy.

Extramucosal pylorotomies were performed by laparoscopy in infants with congenital hypertrophic pyloric stenosis. The surgical technique and precautionary measures taken for the pneumoperitoneum are described in these initial 10 cases. The advantages of this original technique are discussed.

Extramucosal pyloromyotomy by laparoscopy.

We performed extramucosal pyloromyotomies by laparoscopy in 20 infants presenting with congenital hypertrophic pyloric stenosis. The surgical technique and precautionary measures, the outcome, and the advantages of this original approach are discussed. In the near future, laparoscopic pyloromyotomy is likely to become a widely used technique.

[Extra-mucosa pylorotomy by laparoscopy]. / La pylorotomie extra-muqueuse par laparoscopie.

An extramucosal pylorotomy was performed in infants with hypertrophic pyloric stenosis made possible by laparoscopic progress. After performing six cases by laparoscopy, the authors describe what precautionary measures must be taken for the pneumoperitoneum, the instruments utilized, and the advantages of this technique. It appears very likely that laparoscopic pyloromyotomies will become a widespread practice in the future.

In the operation proposed the tumour is approached by the abdominal route after incision of the diaphragm. It is dissected and the overlying healthy oesophagus is stripped. Continuity of the digestive tract is re-established by tubular gastroplasty in which the stomach is brought up to the neck through a retrosternal tunnel. The operation is indicated for tumours of the lower and middle oesophagus.
