Extração de fitobezoar gástrico por videolaparoscopia: considerações técnicas originais

Videolaparoscopic surgery has been used for treatment of almost all surgical abdominal diseases, mainly where there are no large ressections, or operative field is limited. In these situations, laparoscopic surgery has the advantages of less morbidity, quick recovery and good cosmetic results. Bezoars removal, or its mobilization, is probably included in these possible proceedings. Three non-laparotomic procedures were described: 1. endoscopic-laparoscopic; 2. videolaparoscopy and mobilization of intestinal bezoar to the cecum; 3. laparoscopy and gastrotomy for bezoar removal, through suprapubic incision or the umbilical punction. There have been only two publications describing the videolaparoscopic method for bezoar removal, and the methods applied can be complications or morbidity related. We describe one case where the applied technique is simple and easy to perform, time saving and probably less complications-related. This technique, with four trocars, utilized a plastic bag besides the stomach to be opened, followed by gastrotomy, bezoar removal and immediate introduction in the plastic bag, suture of gastrotomy and removal through the left subcostal trocar. This technique was feasible and easy to perform, with short operative time, and there were no intra or post-operative complications; the patient was discharged in the second post-operative day, and is without further problems after one year follow-up. We believe that this could be an adequate technique to perform laparoscopic gastric bezoar removal, and the rigid sequence of operative events allows a quick procedure, with minimal contamination. The videolaparoscopy seems to be an adequate access to surgical treatment of gastro-intestinal bezoars, with or without obstruction, and should be the ellected the procedure of choice to begin the surgical treatment, with convertion to laparotomy in case of any intra-operative adversity.

Three port laparoscopic appendectomy technique with low cost and aesthetic advantage

Introduction Despite dating more than 30 years after the first laparoscopic appendectomy, ileocecal appendix resection is still performed by laparotomy in more than 90% of cases, in our country. Aim To describe a technique for laparoscopic removal of the ileocecal appendix with three portals, at low cost and very good aesthetic appearance. Technique Three incisions, one umbilical and two suprapubic are made; permanent material used comprises: grasping forceps, hook, scissors, needle holders, three metal trocars and four other usual instruments, and a single strand of cotton. There is no need to use of operative extractors bags, clips, endoloops, staples or bipolar or harmonic energy instruments. Allows triangulation and instrumentation in the conventional manner. Conclusion The proposed technique is safe and reproducible, easily teachable, at very low cost and can be applied in general hospitals with conventional laparoscopic equipment.

Extrahepatic bile ducts injury: a report on 14 cases

Traumatic injuries of the extrahepatic biliary tract are infrequent, occurring in approximately 0.5% of all patients with blunt and penetrating abdominal trauma. The incidence of this injury due to blunt abdominal trauma is rare. This study reviewed patients with injuries of the extrahepatic biliary tract due to abdominal trauma over a 6-year period to determine the incidence, trauma scores, associated injuries, surgical treatment performed, complications and mortality rate. We report our experience with 14 patients with extrahepatic biliary tract trauma. A review of the literature and the discussion about the management are presented.

Transversus Abdominis Release (TAR) Robótico: é possível oferecer cirurgia minimamente invasiva para os defeitos complexos da parede abdominal?

We describe the preliminary national experience and the early results of the use of robotic surgery to perform the posterior separation of abdominal wall components by the Transversus Abdominis Release (TAR) technique for the correction of complex defects of the abdominal wall. We performed the procedures between 04/2/2015 and 06/15/2015 and the follow-up time was up to six months, with a minimum of two months. The mean surgical time was five hours and 40 minutes. Two patients required laparoscopic re-intervention, since one developed hernia by peritoneal migration of the mesh and one had mesh extrusion. The procedure proved to be technically feasible, with a still long surgical time. Considering the potential advantages of robotic surgery and those related to TAR and the results obtained when these two techniques are associated, we conclude that they seem to be a good option for the correction of complex abdominal wall defects.

Robotic Roux-en-Y gastric bypass: operative results in 100 patients

Background Laparoscopic gastric bypass is gold-standard for morbid obesity treatment. Aim To describe the results of robotic gastric bypass for morbid obesity patients. Method Were operated on 100 morbidly obese patients through totally robotic gastric bypass between 2013 and 2014. They were 83% female. The age ranged from 20 to 65 years old (medium 48,5 years); the body mass index varied between 38-67 (medium 42,3 kg/cm2). The procedure was designed with 3 cm long gastric pouch, 1 m biliopancreatic limb, 1,2 m alimentary limb, manual or stapled anastomosis. There were four super-super-obese patients and four revisional surgeries. Results Docking time varied from 1 to 20 min (medium 4 min). Console time varied from 40-185 min (medium 105 min). There were no intra operative complications or mortality. There were two lower limb deep venous thrombosis. There was no readmission in the first 30 days. Conclusion Totally robotic gastric bypass is safe and reproduceable, with excellent results even during the initial experience with regular surgeries, revisional surgeries or in super-obese patients. Adequate training may shortens or obviates the learning curve.

Cardiomiectomia com fundoplicatura parcial videolaparoscópica no tratamento do megaesôfago não avançado: estudo de 50 casos

This is a prospective study of 50 patients with non-advanced achalasia treated by videolaparoscopic cardiomyectomy with partial fundoplication. The technical standardization of the operative procedure was evaluated, and the patients studied by clinical evaluation, endoscopy, eletromanometry, radiology and 24 hour pHmetry. The operation was completed laparoscopically in all patients, with no convertion to laparotomy. There were six (12%) intra-operative complications (mucosal perforation, pleural lesion and subcutaneous emphysema), two (4%) immediate post-operative ocurrencies and one (2%) death. There was no late complication. Clinical evaluation showed significant improvement of dysphagia, no regurgitation and weight gain after operation, and excellent and good results were obtained in 97.9% of the patients. In the post-operative period ocurred radiological improvement of esophageal dilatation and less endoscopic esophagitis. The eletromanometry showed significative decrease of lower esophageal sphincter pressure after operation, as well as 24 hour pHmetry verified less esophageal stasis and no gastro-esophageal refluxo There was no difference in the treatment of chagasic or non-chagasic patients. The benefits of laparoscopic surgery were obtained: less pain, early oral intake, short hospitalization and fast return to norma activities.

Correção laparoscópica de hérnia diafragmática traumática crônica

Diaphragmatic hernia secondary to blunt or penetrating trauma is rarely by itself a fatal event. However, if unpercieved, it may lead to severe complications caused by herniation of abdominal contents to the ethorax. Blunt trauma related to car accidents is the most frequent cause of diaphragmatic hernias. Associated injuries are frequently observed, provoked by severe traumas of great impact. These blunt trauma hernias occur mainly on the left side due to abdominal anatomy, since the liver is usually located on the right side. When injuries are observed on the right they tend to be more severe, generally related to major trauma of solid organs. Less frequently diaphragmatic hernias may be bilateral. The management of diaphragmatic injury would appear to be a simple matter of suturing the defect. However, peroperative diagnosis can be difficult and even at the time of surgery some diaphragmatic injuries can be overlooked if carefull exploration is not done. Associated injuries tend to divert attention from the diaphragmatic injury. Laparoscopic diagnosis and repair have been described with successfull. Laparotomy or thoracotomy can be employed for surgical repair of traumatic diaphragmatic hernias. Standard (laboratory/imaging) examinations may fail to make the diagnosis. Recently, the laparoscopic approach has proved useful for more precise evaluation of such injuries, very often allowing immediate repair of these lesions.
