[Spinal subdural empyema. A case report].

Spinal subdural empyema is a very unusual condition. About 40 cases have been previously reported. The authors describe another case, mentioning the difficulties in diagnosis particularly when no primary infection is known. In these circumstances, the neurological signs and MRI are important; MRI demonstrates the level of the lesion and its subdural localization. Surgical treatment and antibiotics are clearly indicated and the earliest it is done, the better the results.

[Laparoscopic treatment of common bile duct lithiasis].

With the advances of videolaparoscopic surgery, this approach had become the treatment of choice for cholelithiasis. However, about 5% to 10% may present common bile duct lithiasis. Most surgeons have still difficulties to deal with this situation and do prefer resolve with open surgery or with further endoscopic approach. We present a case of a 60-year-old man, with 18 months history of right upper quadrant pain, weight loss and jaundice. He was referred with diagnostic of pancreatic cancer. Laboratory investigation showed increased bilirubin (10 mg/dL), alkaline phosphatase and GGT. Abdominal ultrasound showed atrophic gallbladder with dilated intra and extrahepatic biliary tree. Computerized tomography scan disclosed enlarged biliary tree with 3 cm stone in the distal common bile duct. The patient underwent a laparoscopic cholecystectomy followed by choledochotomy and retrieval of the large stone. A latero-lateral choledochoduodenum anastomosis was then performed to decompress the biliary tree. The patient had an uneventful recovery being discharged at the 6th postoperative day. Laparoscopic management of choledocholithiasis is feasible in many patients, specially those with dilated biliary tree. The retrieval of stones may be followed by biliary drainage with T-tube. In some elderly patients with chronically dilated common bile duct, as in the present case, a choledochoduodenal anastomosis is the procedure of choice.

[Contribution to the study of devascularization of esophagogastric transition in the treatment of esophageal bleeding varices].

The usual techniques of esophagogastric desvascularization associated with splenectomy are reviewed and a new one is presented. It is a variant of EGDS technique described by Espíndula (1978) with the following modifications: A) In order to get a possible reduction of the transudation at the dissected area, on reperitonize: 1) the lesser curvature of stomach, naked during proximal gastric vagotomy (PGV). Fig. 1a and 1b; 2) the area of peritoneum concerning splenic hilum and tail of pancreas; 3) the dissected area of distal esophagus, performing a fundoplication (Lind, 1965) that also serves to obtain a good anti-reflux procedure. The EGDS was complemented with endoscopic sclerosis of varices, three to six months after operation. On consider that endoscopic sclerosis substitutes the surgical suture of the varices and reduces the surgical time and morbidity. From 1987 to 1989, eight patients with esophageal varices and gastrointestinal bleeding secondary to mansonic schistosomiasis were operated upon. Based on Child classification, two of these patients (25%) were graded B, six (75%) were graded A. None of the patients had post-operative esophageal bleeding or reflux esophagitis. There were no mortality. Two patients had postoperative ascitis that disappeared with clinic measures. The patients were followed during a period of six months to two years.

[True splenic cyst treated with++videolaparoscopy. Case report and review of the literature].

True non-parasitic splenic cysts are uncommon, their real incidence is difficult to determine since over 30% are asymptomatic. Preoperatively these cysts are rarely diagnosed correctly and they are often findings on examinations. Partial or total splenectomy is the treatment of choice after ruling out splenic hydatidosis, since it is responsible for two thirds of global incidence. Currently, with the technological advances of surgery, especially of videolaparoscopy, some authors have proposed its use for partial cystectomy or splenectomy. The authors present the case of a true splenic cyst (epidermoid) which was resected videolaparoscopically and they discuss aspects of diagnosis and management.

[Videolaparoscopy gastrectomy for complicated peptic ulcer: technique and case report].

Since the introduction of H2 receptor antagonists and inhibitors of the acid pump, the indications for the surgical management of peptic disease have decreased significantly. However some patients presenting bleeding, perforation, gastric outlet obstruction and intractable peptic ulcer still need surgical treatment. The first laparoscopic Billroth II gastrectomy was performed in 1992. To date, laparoscopic gastrectomy has been performed by a small number of surgeons around the world. The aim of this study was to present a case of totally laparoscopic Billroth II gastrectomy and to describe an alternative technique using endoscopic stapling devices. We present a case of a 48-year-old man, complaining of severe epigastralgia, who had a 20-year history of peptic ulcer. Gastroscopy had revealed a duodenal ulcer and a deformity of the bulbus. A diagnosis of intractable peptic ulcer was made, and the patient underwent laparoscopic Billroth II gastrectomy with side-to-side intracorporeal gastrojejunostomy using endoscopic stapling devices. On postoperative day 1, he was able to walk. On postoperative day 3, he started on a clear liquid diet and was discharged on postoperative day 6. During his postoperative recovery, the patient experienced little pain and did not request narcotic analgesia. Laparoscopic gastric resection is an alternative to open procedure in well selected cases.

[Barrett esophagus in the esophageal stump after subtotal esophagectomy with cervical esophagogastroplasty].

In 48 patients that suffered subtotal esophagectomy and were submitted to esophagogastroplasty a long term follow-up study was carried out. In four of these patients (8.3%) pathological changes that characterize Barrett's esophagus were found in the esophageal stump. As far as we could verify, such changes were never reported at this localization before. The Barrett's esophagus seems to be intimately linked to reflux esophagitis resulting from the action of acid-peptic and biliary secretions.

[Laparoscopic treatment of duodenal obstruction in a patient with pancreatic cancer].

We present a case report of laparoscopic gastrojejunostomy in a patient with duodenal obstruction from unresectable cancer. We performed an side-to-side intracorporeal gastrojejunostomy using endoscopic stapling devices. The patient had no morbidity and he was discharge on fourth postoperative day. Laparoscopic gastric bypass is an alternative to open procedure in well selected cases.

[Video laparoscopic splenectomy in a patient with splenomegaly due to hereditary spherocytosis: report of two cases].

We present a case report of laparoscopic splenectomy in two patients with congenital spherocytosis. A 23-year-old man and a 25-year-old woman with splenomegaly due to congenital spherocytosis underwent laparoscopic splenectomy. Their postoperative course was uncomplicated and they were discharged on the second and fourth postoperative day, respectively.

[Laparoscopic treatment of non-advanced esophageal achalasia: technical aspects].

Laparoscopic cardiomyotomy has recently became a popular alternative to traditional laparotomy in the management of patients with nonadvanced achalasia. The laparoscopic approach for this disease is encouraging due to the low rate of complications associated with a shorter recovery period and reduced postoperative pain. This article describes an alternative technique in the laparoscopic treatment of achalasia with introduction of a supplementary 5 mm port in order to facilitate the cardiomyotomy and the construction of the valvuloplasty.

An alternative technique for open laparoscopy.

Laparoscopic cholecystectomy has become a routine surgical procedure. Complications related to use of the laparoscope frequently result from insertion of a Veress needle or blind introduction of the primary cannula on its trocar. This risk is clearly higher in patients who have undergone previous surgical operations. Open insertion with visualisation of abdominal cavity before the introduction of the primary cannula reduces the risk of major vascular and visceral injury. Nevertheless, open laparoscopy has rarely been adopted mainly due to gas leak from the wound and because it is time-consuming. A simple, quick and effective technique is described. The authors experience with this technique in the last 500 cases has shown that it has no effect on the duration of operation, and does not involve a larger skin incision. This technique has been associated with no operative difficulty.
