Paracolostomal hernia: repair with use of a Dacron prosthesis.

Several surgical procedures have been described for the repair of paracolostomal hernia. We describe a local technique approach using stoma relocation with insertion of a Dacron prosthesis. Among 14 patients operated on for paracolostomal hernia, this technique was used in 10 patients. There was no mortality or morbidity (no prosthesis infection). During follow-up there was one recurrence, which was reoperated with a good final result. This technique can be recommended for the few patients in whom a surgical repair is mandated.

Colonic involvement in acute necrotizing pancreatitis: results of surgical treatment.

In this series of 15 personal cases, the authors emphasize the unusual colonic complications which occur during acute necrotizing pancreatitis. These lesions always indicate a particularly severe pancreatitis and depend on 2 factors: extension of pancreatic necrosis into the mesocolon with encasing pericolic tumoral fibrosis, and parietal ischemic necrosis secondary to shock and thrombosis with infection. Laparotomy followed by colectomy is indicated in these severely ill patients. Prognosis is poor (8 deaths of 15 patients), sometimes in spite of extensive pancreatic excision. The existence of colonic complications gives evidence of the particular severity of certain forms of pancreatitis.

[Acute abdominal syndromes and anisakiasis. A new case (author's transl)].

To the list of the well known parasitic diseases which are expressed by acute abdominal syndromes and which need laparotomy, we may now add the anisakiasis. At the end of a complex cycle, the ingestion of herring can infected man : frequently the parasite is fixed at the level of the stomach, or of the ileum and seldom at the level of the bowel. Its presence gives rise to pain, hemorragy, tumor or occlusion in relation with the parietal granuloma. From one personal case the authors analyse the originality of this parasitic disease, the difficulty of its diagnosis before surgical time and its good prognosis.

[Peroperative ultrasound scanning of the pancreas].

Intraoperative realtime high resolution ultrasound scanning of the pancreas seems to be a new and promising procedure. We have performed it in 28 patients: the normal ultrasound picture of pancreatic ducts and parenchyma was defined in 9 patients without pancreatic disease; in 19 patients with pancreatic disease, intraoperative ultrasound was compared with preoperative ultrasound examination. Seven of 8 patients with pancreatic carcinoma and 4 of 6 with calcifying chronic pancreatitis had positive findings, respectively. In 3 cancer patients, intraoperative ultrasound investigation avoided a long and unavailing dissection of the tumor by revealing extensive spread. In selected cases, intraoperative sonography allowed to characterize and to localize pancreatic carcinoma: portal vein invasion, relationship of the tumor to the duct of Wirsung and small hepatic metastases. In chronic pancreatitis, intraoperative ultrasound information concerning the dimensions of the pancreatic duct, the structure and the localization of pseudocysts was comparable to that obtained by radiological opacification. Furthermore, intraoperative ultrasound exploration guided proper incision and evacuation of pancreatic pseudocysts in two patients. Operative ultrasound seems to us to be mandatory during pancreatic surgery. Further experience with this technique is needed in a larger number of patients. However, we believe that it could replace intraoperative cholangiography and pancreaticography in the assessment of extension and complications of pancreatic disease.
