[Intestinal pneumatosis].

Intestinal pneumatosis is an infrequent disease of difficult clinical and radiologic diagnosis. It may be accompanied by pneumoperitoneum in up to 30% of the cases leading to differential diagnosis with pictures of visceral perforation. We herein present 4 cases of intestinal pneumatosis in whom pneumoperitoneum was associated in 3 patients. Diagnosis was intraoperative in 2 patients submitted to emergency surgery because of an associated acute gastrointestinal event (intestinal volvulus and acute cholecystitis). The other 2 cases were diagnosed by computerized tomography and colonoscopy, respectively, and given their satisfactory clinical evolution they received conservative treatment. The course of the disease was favorable in all the patients with the radiologic signs of pneumatosis disappearing.

[Colangiocarcinoma on a choledochal cyst].

Patients with choledochal cysts have an increased incidence of biliary tract carcinoma. We report a case of adenocarcinoma arising in a type I choledochal cyst which was surgically treated by resection and biliodigestive anastomosis (hepaticojejunostomy).

[Laparoscopic cholecystectomy: 3 years of experience at a university hospital].

We analyse the first 174 patients treated with laparoscopic cholecystectomy (LC) and their follow-up results. Average age was 57 years. Intraoperative cholangiography was not done in anyone. Conversion rate into other forms of intervention was 6.3%. The rate of common bile duct injury has been null. Total morbidity was 6.3%. Two cases of pulmonary embolism and two biliary leakages stand out in the postoperative morbidity. There was no death. After a follow-up period of up to 36 months, only 1 case of residual choledocholithiasis was registered, and it was cured with endoscopy. In this series morbid-mortality figures are low. LC is a safe procedure in the treatment of cholelithiasis, even in older patients.

[Acute cholecystitis and laparoscopic cholecystectomy. Comparison with non-complicated cholelithiasis].

Laparoscopic cholecystectomy has become the treatment of choice for symptomatic cholelithiasis. However, the indication of the laparoscopic approach for acute inflammation of the gallbladder in unclear and further analysis of the results is required. The aim of our study was to compare the results of laparoscopic cholecystectomy after uncomplicated cholelithiasis and after acute cholecystitis. Data from 201 patients who underwent laparoscopic cholecystectomy were collected prospectively. Uncomplicated cholelithiasis was present in 149 patients and 52 individuals had acute cholecystitis. No differences in age, sex distribution or associated diseases were observed between groups. The mean operative time was significantly higher in patients with acute cholecystitis. However, no difference was observed regarding conversion rate (7.3%-7.6%) and morbidity rate (8.7%-9.6%). No mortality has occurred in any group. The average hospital stay after laparoscopic cholecystectomy was greater when acute cholecystitis was present (2.6 days-4.9 days; p < 0.01). But in this case hospitalization was shorter than after elective conversion (8 days; p < 0.001 and p < 0.05). We conclude that patients with acute cholecystitis can undergo laparoscopic cholecystectomy safely, with low morbidity and mortality rates and reduced hospital stay.

Experimentally contaminated reabsorbable meshes: their evolution in abdominal wall defects.

Contamination by septic materials may represent an important handicap in evaluating the tolerance of reabsorbable prostheses, increasing the possible onset of abdominal fistulae. This is also the case when these materials are used in the treatment of abdominal wall defects. Nevertheless, reabsorbable meshes exist that allow visceroprosthetic contact without risk, thus making it possible to use them in spite of the presence of infection. We have performed this experimental study with the aim of evaluating the behaviour and evolution of polyglycolic acid reabsorbable meshes contaminated by septic materials in the treatment of abdominal wall defects. For this purpose, 40 Wistar rats were operated and distributed into two series of 20 animals each. Massive mesh contamination by fecaloid material did not jeopardise the fact that prostheses were well tolerated in experimental animals throughout the reabsorption process, without increasing the incidence of infection.
