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.

Metástases de adenocarcinoma de vesícula biliar em colecistectomia videolaparoscópica

The cancer of the gallbladder unless rare, has been found in about 1% of all cholecistectomies for chronic cholecistitis. The preoperative diagnosis is difficult to be done because there are not particular symptoms. In the present paper the authors relate a case of a patient submitted to a laparoscopic cholecistectomy for acute cholecistitis. The pathologist reported a concomitant tubular adenoma in the specimen. At the 6th postoperative month the patient had intense abdominal pain, and at the 7th month, metastasis of an adenocarcinoma was detected in the port sites. The first specimen was reviewed and showed a primay adenocarcinoma of the gallbladder. The patient was submitted to chemotherapy but with few response, dying in the 9th postoperative month. The authors conclude that unless difficult, the preoperative diagnosis of cancer of the gallbladder is essential for a more appropriate therapy, mainly in the patients aging more than 50 year when the neoplasm appears with greater prevalence. Despite the videolaparoscopic access for the surgery provides low morbidity and mortality, it is not indicated for the gallbladder cancer when the conventional access by laparotomy is obligatory.

Leiomioma do esôfago removido por videolaparoscopia

This report describes a leiomyoma of the inferior third section of the esophagus removed during laparoscopic cholecystectomy. The patient is a woman 55-years-age, carrying esophageal myoma of 40 mm in diameter wide, situated in the posterior wall of the lower esophagus. Indications for surgery were based mainly on the growth of the mass (6 mm when discovered 7 years previously, increased to 40 mm). Recently the patient returned suffering from pain, which could be attributed to his litiasic cholecystopaty. A small degree of low disphagia could also be observed. Radiologic imaging, direct endoscopic examination and endoscopic ultrasound showed that the mioma protruded on to the oesophagic lumen, discreetly diminishing there. A laparoscopic esophageal myomectomy was indicated at the same session of the laparoscopic cholecystectomy. Once the pneunoperitoneum was installed, five ports were placed as if for a hiatus hernia surgery. The cholecystectomy was uneventful. Next, an esophagoscopy was performed so as to determine the precise area covering the base of the tumour; at the right-lateral site. Longitudinal and circular fibres of the esophagus was severed over the lesion and the enucleation of the tumour was performed alternating the monopolar dissection, bipolar and hidrodisection. Control-endoscopy was carried out to verify mucosa integrity. Four suture points with poliglactine 3-0 string so as to close the musculature followed this. One suture was placed in for diminution of the size of the esophagean hiatus. Total time of intervention: two hours (30m for the cholecystectomy and one hour and thirty minutes for the myomectomy). Postoperative period: uneventful. Disappearance of the disphagia was observed. Radiologic transit control with water-soluble contrast at 4th post-operative day: good passage. Diagnosis from laboratory of pathology: conjunctive tumour formed by muscle non-striated cells: leiomyoma. The patient was re-examined on the two-month postoperative follow-up. General conditions were good and there were no complain of dysphagia. Neither there were any symptoms of gastro-esophageal reflux.

Tratamento laparoscópico dos cateteres de diálise peritoneal obstruídos

The success of peritoneal dialysis in the treatment of patients with chronic renal failure depends on a proper performance of peritoneal catheter. This study shows the experience from the Service of Surgery from Departament of Medicine of State University of Maringá and the Service of Nephrology from Maria Auxiliadora Hospital, Maringá, in the laparoscopic approach of catheters with obstruction.

Descoberta simultânea de carcinomatose disseminada e carcinoma de cólon, após colecistectomia laparoscópica

A particularly rapid and fatal outcome has been noted in cases of malignant soft-tissue metastases occurring after cancer surgery. Abdominal wall metastases occurring in scars after laparotomy for cancer resection show a similar poor outcome. On the other hand, neoplasm seeding at trocar sites after laparoscopy has been reported with an increasing frequency. A case is presented of a 68-years-old woman with metastatic seeding of non-diagnosed colon cancer at the umbilical trocar site used for a laparoscopic cholecystectomy. The gallbladder was extracted through the umbilical incision. Pathological examination confirmed chronic cholecystitis. Eight months latter, the patient was seen with a tender umbilical mass protruded through a 4,5 cm the umbilical incision site. Biopsies of this tissue were taken and histopathological examination showed metastatic adenocarcinoma, probably of a gastrointestinal origin. A colonoscopy performed at the same time revealed a 2-cm lesion at the hepatic flexur which was shown to be a differentiated adenocarcinoma. An 8.0 x 6.0 x 6.0-cm pelvic mass without signs of liver metastases was identified by computerised tomography. Diagnostic laparoscopy showed a diffuse peritoneal carcinomatosis. The pelvis could not be approached, except for simple biopsy, and no surgical procedure was performed. It is presumed that the primary colon cancer existed prior to cholecystectomy. Laparoscopy is the procedure of choice to perform cholecystectomy and fundoplication. It has also been increasingly used to diagnose, resect and perform the staging of malignant tumours. As in any relatively new technique, questions arising about its safety and risk of complications must be extensively studied. Many questions about the specific features of laparoscopy promoting cancer growth remain unanswered.

Hepaticojejunostomia em "y" de roux videoassistida

Management of common bile duct stones in the era of laparoscopic surgery is controversial. The biliary anastomosis is indicated in case of large common bile duct, recurrent stones, giant stones and concomitant common bile duct stricture and duct stones. The development of laparoscopic techniques permits to perform this type of surgery laparoscopically as well as the open procedure.

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.

O estado da arte da cirurgia do baço, no início do século XXI

In the last fifty years evolution of scientific knowledge on the spleen provoked an entirely new approach to splenic surgery. It was shown that virulence may emerge as a significant consequence of environmental and evolutionary changes of some microbial communities, and devastating pathogenetic results of these changes become visible in human hosts without the splenic function. In other words: the spleen plays a pivotal role in the dynamic balance between biodiversity, microorganisms and immunogenecity in human hosts. Therefore, to preserve the "splenic immunologic repertoire" became an increasing commitment among surgeons. Understanding the integration of these multiple information on spleen, seems central to understand the new splenic surgery. Partial splenectomies (Réglées) - based on anatomical, experimental and clinical studies, developed at the University of Minas Gerais since the fifties - were successfully applied initially to treat the traumatic injuries of the spleen; in a following step, partial splenectomy were used to control hematological diseases. "Réglées" techniques on the spleen have conquered "ethical support, consilience status and clinical governance" to give birth to surgical therapeutic decisions on the spleen, in order to spare the structural integrity of the immune system. Splenic réglées procedures became a seminal achievement of splenic surgical practice. Initial results of "Partial splenectomies" - with conventional surgical armamentaria and techniques - were confirmed and improved by the introduction of techniques based on laparoscopic and endovascular approaches. And current usage of surgical splenic saving procedures propitiated the emergence of an appropriate lexicon for medical communication and became an "end point" of a "long-standing surgical inhibition" over the spleen.

Complicações de procedimentos laparoscópicos em urologia: análise retropectiva de 1990 a 2002

Although laparoscopic surgery is a safe and effective procedure, it is not exempt from risks of complications and death. Complication rates have decreased in various procedures, with means of 1%, 3.9% and 9.2%, for those considered easy, difficult and very difficult, respectively, while death rates have ranged from zero to 0.09%. To analyze the characteristics and the incidence of complications regarding the technique, the patient, the surgeon and the various types of laparoscopic procedures used in urology. A literature review between January 1990 and June 2002 in Medline and Lilacs was undertaken, including approximately 22,000 patients submitted to laparoscopic surgery, classified according to the type of procedure. The complications were considered as major or minor in accordance with various criteria adopted by the authors for appraising their seriousness. The complications regarded as minor ones occurred mainly in the phases of access and insufflation, and were more common in the postoperative period. The ones considered as major were associated with the dissection phase, with more serious characteristics, with vascular lesions predominating over visceral ones. The laparoscopic urological procedures proved to be well tolerated by pediatric and obese patients. Complications rates with this technique were inversely proportional to theexperience of the surgeon; they were associated with the complexity of the procedures and were similar to those of the corresponding procedures performed through an open approach. Over ten years, in spite of the increasing complexity of laparoscopic procedures, complications rates have fallen to figures comparable to those of the corresponding open techniques.

Hepatectomia direita por videolaparoscopia

The first application of laparoscopic liver surgery consisted of wedge liver biopsies or resection of peripheral lesions, mostly benign. More recently, reports of anatomic left and right hepatectomy have been seen in the literature. Expertise in some centers has evolved to such an extent that even living related donor hepatectomy has been performed. The aim of this paper is to report a laparoscopic right hepatectomy and describe in detail the surgical technique employed. To our knowledge this is the first case performed in Brazil totally laparoscopically. The surgery followed four distinct phases: complete mobilization of the liver; hilum dissection with encircling of right portal vein and right hepatic artery, caval dissection using linear vascular stapler to divide right hepatic vein and parenchymal transection with harmonic shears and firings of linear staplers are used to divide segmental 5 and 8 branches of middle hepatic vein. The liver specimen was removed by Pfannenstiel incision. Intraoperative blood loss was estimated in 120 ml with no need for blood transfusion. Hospital stay was 5 days. Laparoscopic right hepatectomy is feasible, technically demanding but can be safely accomplished by surgeons who have experience in advanced laparoscopic procedures and open hepatic surgery. In Brazil laparoscopic liver surgery is still in its first years and there is a lack of technical description of this complex procedure.

Infecção por micobactérias de crescimento rápido após procedimentos videocirúrgicos - a hipótese do glutaraldeído

Between August 2006 and February 2007, in the state of Rio de Janeiro, Brazil, a massive outbreak of RGM infections after video laparoscopy was mainly associated to the recently described Mycobacterium massiliense species. All confirmed and probable cases reports described the use of high-level disinfection of medical devices by using 2% glutaraldehyde (2% GA) for 30 min before the surgical procedures. We investigated the susceptibility of the M. massiliense isolates recovered during the outbreak to high-level disinfection after 30 min, 1h, 6h and 10h of exposure to the commercial disinfectants. Reference strains for official mycobactericidal tests such as Mycobacterium abscessus, Mycobacterium bovis, Mycobacterium chelonae, Mycobacterium neoaurum and Mycobacterium smegmatis were included as controls. Although all the reference strains were eliminated in 30 min of exposure to 2% GA, we observed the recovery of all M. massiliense clinical isolates even after 10h of exposure. This study suggests that failures in high-level disinfection and the high tolerance of these M. massiliense clinical strains to the 2% GA were strongly associated to the magnitude of the outbreak.

Derivação gastrojejunal com anel de contenção no tratamento de obesidade mórbida em paciente com situs inversus totalis

The gastric bypass is a good option in the therapy of morbid obesity. Nevertheless, it must be considered the rare condition as occurred in a patient with previous abdominal surgery with Situs Inversus Totalis. A 24 year-old male patient with body mass index of 40 Kg/ m², multiple dietary failures, and arterial hypertension as co-morbidities, with a anterior paramedial right incision due to a previous appendicectomy (8 years ago).With a indication for bariatric surgery, was performed Roux-en-Y gastric bypass by laparoscopic procedure, with previous planning of Situs Inversus Totalis.

Hérnia de Petit bilateral espontânea

Petit's lumbar hernia is an uncommon defect of the posterior abdominal wall that represents less than 1% of all abdominal wall hernias. It is more often unilateral and founded in young females, rarely containing a real herniated sac. There are two different approaches to repair: laparoscopy and open surgery. The goal of this article is to report one case of spontaneous bilateral lumbar Petit's hernia treated with open surgery.

Damage control surgery: it's evolution over the last 20 years

In less than twenty years, what began as a concept for the treatment of exsanguinating truncal trauma patients has become the primary treatment model for numerous emergent, life threatening surgical conditions incapable of tolerating traditional methods. Its core concepts are relative straightforward and simple in nature: first, proper identification of the patient who is in need of following this paradigm; second, truncation of the initial surgical procedure to the minimal necessary operation; third, aggressive, focused resuscitation in the intensive care unit; fourth, definitive care only once the patient is optimized to tolerate the procedure. These simple underlying principles can be molded to a variety of emergencies, from its original application in combined major vascular and visceral trauma to the septic abdomen and orthopedics. A host of new resuscitation strategies and technologies have been developed over the past two decades, from permissive hypotension and damage control resuscitation to advanced ventilators and hemostatic agents, which have allowed for a more focused resuscitation, allowing some of the morbidity of this model to be reduced. The combination of the simple, malleable paradigm along with better understanding of resuscitation has proven to be a potent blend. As such, what was once an almost lethal injury (combined vascular and visceral injury) has become a survivable one.

Does a previous surgical experience interfere on psychic stress in patients submitted to major surgery?

OBJECTIVE: to evaluate the impact of stress in patients undergoing major surgeries under general anesthesia, relating their physical and psychic reactions to the different stages of stress. METHODS: we studied 100 adult patients of both genders, who were divided into two groups: Group 1 - 22 patients without experience with surgery; Group 2 - 78 patients previously submitted to medium and major surgery. To investigate the stress, we used the Inventory of Stress Symptoms for Adults, developed by Lipp, the day before the procedure and two days and seven days after the operation. The comparison of groups with respect to gender, pain, and percentage of stress were performed using the Chi-square test, and for the age variable the Student's t test was used. Differences were considered significant at p<0.05. RESULTS: the groups were not homogeneous as for the overall percentage of stress on the three measurements. G1 had decreased postoperative stress, whilst in G2 it increased. Psychological symptoms of stress prevailed in both groups. CONCLUSION: previous surgery reduced preoperative stress but did not affect postoperative emotional disorders.
