[Minor pancreatitis after a Billroth II gastric resection for gastroduodenal ulcer].

Pancreatic complications arising after 117 Billroth II gastric resections carried out between 1976 and 1980 are evaluated. Changes in blood and urinary amylase were noted in 35% of cases. A distinction is drawn between minor forms (MPOP), and major forms (APOP), with an incidence of 34% and 1% respectively. Lastly, the question of aetiopathogenesis is discussed, with particular reference to the causal factors observed on each occasion.

[Dehiscence of anastomosis in surgery of the colon. Causes and prevention].

150 operations on the large intestine performed in 1976-81 are presented with the percentage of dehiscences following surgery. In considering the problem of fistulas arising on the colonic sutures, the more frequent aetiopathogenetic factors are examined. The percentages reported are compared with those produced by the best medical schools. Curves recommended in recent literature are also reported.

[Biliary peritonitis without perforation].

The extreme rarity of this condition is shown and its anatomopathological and clinical features described. Conclusive diagnosis is impossible to formulate preoperatively and emergency surgery is necessary to avoid complications which are always serious in biliary peritonitis. Finally the observed clinical case is described.

[Protective colostomy in surgery of the left colon].

2 groups of patients were given anterior rectal resections, one of the groups also receiving protective colostomy. Results show the usefulness of protective colostomy, not so much because it reduces the incidence of anastomotic dehiscence as because it minimizes the possible consequences of any such dehiscence.

[Postoperative pneumoperitoneum. Incidence, significance, duration].

The phenomenon of post-operative pneumoperitoneum is considered and its formation modalities, incidence, site and duration evaluated. The phenomenon is related to the constitution of the patient and the extent of the operation performed. Differences between post-operative and perforation forms are pointed out.

Central venous catheterization in pediatric patients affected by hematological malignancies.

The objective of this retrospective study was to evaluate the significance and complications of percutaneous central venous catheterization in pediatric patients affected by hematologic malignancies. One hundred and fifty-eight central venous catheters were inserted in 125 pediatric patients (male/female 67/58; median age: 4 years; range 10 m - 6 y.) affected by hematological malignancies. Venous access was obtained by means of a tunnelled silicone rubber Groshong catheter inserted percutaneously in the subclavian vein (91.1%), the internal jugular vein or in the femoral vein. The medial duration of catheterization was 231.8 days (range 8-1014 days). The total number of catheter days was 33,792 (92.6 years). There were no complications related to catheter insertion. Only one patient developed significant post-operative bleeding. One hundred and nine catheters (68.9%) were removed when they were no longer needed and 49 (31.1%) were removed due to complications: 6 catheter occlusions (12.2%), 7 were accidentally withdrawn (14.3%), 3 for local infections (6.1%) and 33 for catheter-related infection (67.3%). A Groshong catheter seems to provide good access to the blood stream for a long period of time with a low incidence of complications in children with acute hematological malignancies.

[Cervical-mediastinal emphysema of abdominal origin].

Cervical mediastinic emphysema usually does not demand emergency procedures: nevertheless its ethiology must be promptly assessed though his achievement may prove less than easy owing the vague clinical presentation and to the limits imposed by regional topography. Among the possible etiologic factors one should take into account the rare abdominal source too. Indeed the cervical region is connected to the retroperitoneal space through a virtual "visceral space" via the thoracic cavity and some diaphragmatic break-throughs variable in size. The communication allows, in some pathologic conditions, the unopposed circulation of air and fluids. Our interest in the topic is due to the occurrence of a cervical mediastinic emphysema in a patient suffering from a colonic perforation.

[Anorectal manometry in hemorrhoidal disease].

Manometry is an important approach to anorectal function. In the haemorrhoids the evaluation of the anal resting tone, of the squeeze and of the sphincterial length is very useful to realize the best surgical treatment. Anorectal manometry is neither invasive nor expensive; it can be ready repeated and the results are reproducible. This examination must be considerated as essential part of the diagnostic routine of the anorectal diseases.

[Submucosal reconstructive hemorrhoidectomy (A.G. Parks operation)].

Indications and procedure of submucosal reconstructive hemorrhoidectomy (A.G. Parks hemorrhoidectomy) are described and discussed. This procedure is more difficult and time consuming than other techniques, but results are better in high degree hemorrhoids. Authors consider complications and sequelae on 278 patients operated in their Department.
