[Surgical treatment of esophageal diverticula].

The aim of this paper is to evaluate the methods and therapeutic principles of esophageal diverticula pathology. We analyze the main pathological mechanisms which establish the therapeutic attitude linked with a complex pretherapeutic evaluation. In our study we enrolled 12 patients operated between 2001-2009 for esophageal diverticula with different topography.

[Gastrointestinal stromal tumor (GIST)--medical rarities?].

Although their overall incidence is low, GISTs are distinctive subgroup of gastrointestinal mesenchymal tumors which express CD117 or platelet derived growth factor receptor alpha (PDGFRA). Considered as rare digestive cancers, tumors like schwannomas, neurofibromas, gastrointestinal leiomiomas are now reclassified as GIST based on immunohistochemistry studies. GIST are more frequent in stomach (40-70%), small bowel (20-40%), colon (5-15%), meanwhile locations such as mesentery, omentum, retro peritoneum in less of 5%.

[Cholangiocarcinoma of the distal bile duct--case presentation].

Cholangiocarcinoma is a rare disease (0.15-0.16% in the general population).

[The open packing of the lesser sac technique in infected severe acute pancreatitis].

The surgical technique we applied was the classical one with several improvements. Firstly, the timing of intervention is delayed until the occurrence of the clearly defined infected necrosis. Secondly, we limited the propagation of infection in submesocolic peritoneal cavity by creating this omental laparostomy with suturing the cutting edges of the gastrocolic ligament to the supra-umbilical anterior parietal peritoneum, near to the laparotomy, achieving the "marsupialisation" of the lesser sac.

[Difficulties in diagnosis and surgical treatment of a giant retroperitoneal lipoma].

Primary retroperitoneal tumors are relatively rare and the histological characters vary. We present the case of a retroperitoneal lipoma in a 51-year-old male patient, whose main complain was enlarging of the abdomen in the last 2 months. The CT of the abdomen and pelvis revealed a giant retroperitoneal tumor.

[The role of esophageal manometry in the management of the patients with gastro-esophageal reflux disease and Barrett's esophagus].

Aim: To analyze the correlation between the failure of medical treatment in patients with reflux esophagitis or Barrett esophagus and LES function, manometrically measured.

Methodology: This is a prospective study of 24 patients admitted in our clinic for reflux disease symptoms, who were investigated by endoscopy (combined with biopsy), esophageal manometry and 24 h pH monitoring. The including criteria for the patients was abnormal esophageal exposure to acid reflux, each patient having abnormal 24 h pH monitoring (pH < 4 in the esophagus more then 4.

[Caudal anesthesia in pediatric surgery].

Unlabelled: The study analyses the efficacy and the safety of caudal anesthesia for the intra and postoperative pain management in children.

Material And Method: A retrospective study was conducted over a five years period enrolling 150 children scheduled for various surgical procedures. We used the standard technique ("loss of resistance", "single shot", lateral decubitus).

[CSF leaks--diagnostic and therapeutic approach].

The paper presents the classification of the CSF leaks and their etiology. The authors insist on the post surgical causes and on the modem diagnostic procedures such as 2 transferrin and trace protein determination and high resolution CT. They also present their own experience in repairing defects from the anterior skull base under endoscopic control.

[Preoperative modern evaluation of patient with esophageal stenosis].

It is well known the difficulty of a precise evaluation in the pretherapeutic stage of any esophageal pathology, especially that of obstructive lesions. Preoperatory information should be as accurate as possible, any evaluation error leading to surgical manoeuvres that can later be regretted. From the current practice one can easily observe that there is no typical exploratory protocol, each having its own specific limits, high costs that are not negligible, and some of them are not always immediately available.
