ObjectiveThe purpose of this report is to describe the authors' technique for the laparoscopic repair of paraesophageal hernias and the outcome in their series of patients.
MethodsThirty patients underwent elective laparoscopic repair of paraesophageal hernias. All were pure type 11 paraesophageal hernias as defined by upper gastrointestinal contrast studies. All operations were performed by a single surgeon (JKE) assisted by five different chief surgical residents. The authors have used various prototypes of a laparoscopic utility belt to reduce the physician requirement to the surgeon and a first assistant. The operative setup and specific techniques of the repair are described and illustrated. A concomitant anti-reflux procedure was performed in the last 23 patients.
Laparoscopic-assisted aneurysmectomy is safe and effective and can be performed with good results. The longer operation time required is well tolerated in patients who are at good and moderate risk. Prior training in laparoscopic aortic surgery is necessary for surgeons to obtain the required level of expertise needed to perform these procedures. With these caveats, the results of our study suggest that laparoscopic-assisted aortic aneurysmectomy is appropriate for moderate-to-good risk (American Society of Anesthesiologists class of III or lower) operative candidates meeting standard criteria for aneurysm resection in whom preoperative computed tomography scan and biplane arteriography demonstrate a proximal aneurysm neck of 0.5 cm or larger and no need for visceral or internal iliac artery reconstruction. A randomized trial would be required to confirm the benefits of this procedure over open aneurysmectomy.
A patient with a recently placed ventriculoperitoneal shunt suffered ventilatory impairment due to decreased thoracic compliance related to massive subcutaneous emphysema during laparoscopic cholecystectomy. The patient recovered uneventfully; however, recently established closed communication between the peritoneal cavity and the subcutaneous space may be a relative contraindication to laparoscopic surgery.
The laparoscopic approach to infrarenal AAAs appears feasible, with several potential advantages in low- and moderate-risk patients. Once the technique is optimized, randomized prospective studies will be needed to verify the apparent benefits demonstrated by these initial patients.
These early observations suggest that the laparoscopic treatment of infrarenal abdominal aneurysms may have several significant potential benefits. Long-term results and randomized prospective studies with patients matched by risk stratification will be needed to confirm these impressions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
