[Intermediate term results after arthroscopic meniscus suture].

QUESTION: Do results after arthroscopic meniscal repair justify the bigger expenditure and the longer rehabilitation opposite to the arthroscopic menisectomy? METHOD: An arthroscopic meniscal repair in inside-out technique was carried out by the same surgeon in 35 consecutive patients with meniscal tears (tears at the meniscocapsular junction with best prognosis after repair are not subject of this study). Rehabilitation was standardized. After a mean follow-up time of 43 months, 27 (77%) of these patients, 12 without and 15 with an additional anterior cruciate ligament (ACL) reconstruction, were evaluated personally. RESULTS: There were 4 (14.8%) reruptures (3 true reruptures, 1 "rerupture" out of the repair side) and I lesion of the N. saphenus with limited dysaesthesia. Three of the 4 reruptures occurred in patients with isolated meniscal repair, only one in patients with additional ACL-reconstruction. The functional results (Lysholm-score, knee mobility) and the subjective result were good in patients without reruptures. Postoperatively, patients were unable for work and sports for a long time, but these times being shorter for isolated meniscal repairs (5.4 and 12 weeks respectively) than for patients with an additional ACL-reconstruction (12 and 29 weeks respectively). CONCLUSIONS: In terms of knee function and osteoarthrosis, arthroscopic meniscal repair has better results than partial meniscectomy and should be preferred, therefore, especially in young patients. A sufficient number of meniscus sutures should be performed and existing ligament instabilities should be repaired. A good rehabilitation program is essential. Efforts for a better acceptance of the method in patients and family doctors are necessary.

[Herniation of the cecum and ascending colon through the Winslowi foramen in the bursa omentalis].

Herniation through the foramen of Winslow (HFW) is exceedingly rare, the ileum, coecum or ascending colon is involved mostly. One new case is presented here to illustrate the clinical findings, which are often discreet, and the characteristical radiographic features, which can lead to definitive preoperative diagnosis. Treatment is by surgical reduction of the hernia, resection of non-viable bowel or fixation of coecum and ascending colon. Closure of the foramen is generally considered unnecessary. Without delay in diagnosis and treatment, the former high letality rate of the condition is now nearly zero.

[Cystic lymphangioma of the transverse mesocolon].

Intraabdominal cystic lymphangiomas are very rare. One new case of the disease is presented here: a 10-year-old boy undergoes laparotomy because of suspected appendicitis acuta, a cystic tumor in the transverse mesocolon is found and a segmental colon resection with primary anastomosis performed. Histologic examination of the tumor leads to the diagnosis of cystic lymphangioma. The postoperative course is uneventful. History, clinical features, diagnosis, therapy and pathologic-anatomical findings are discussed and the literature is reviewed.

[Liver transplantation. Preliminary results in the district University Hospital of Geneva].

Between July 1987 and May 1989, 11 liver transplants were performed on 10 patients at the University Hospital of Geneva. Of 15 patients evaluated for elective transplantation, 10 were accepted and put on the waiting list. 5 patients were rejected because of a contraindication or because another treatment seemed preferable. 8 transplantations were eventually performed. Emergency transplantation was considered for 6 patients, but could be performed in only 3. Indications for transplantation were as follows: one hepatocellular carcinoma in a non-cirrhotic patient, 2 post-hepatitis cirrhoses (one B and one non-A-, non-B), 3 primary biliary cirrhoses, one autoimmune cirrhosis, one primary sclerosing cholangitis, one cirrhosis on alpha-1-antitrypsin deficiency, and one fulminant B-Delta hepatitis. Most of these patients had advanced liver disease and a limited life expectancy. 8 of the 10 patients transplanted are nevertheless alive and none is hospitalized at the present time. More than mere survival, however, quality of life regained after transplantation prompts us to consider transplantation early in the progress of the disease. Earlier evaluation of patients would make transplantation feasible soon after the first complication of the disease. This attitude would probably prevent patients from dying while on a waiting list and decrease operative as well as early postoperative risks. Better information and coordination regarding potential donors is necessary in Switzerland to obtain better results in organ transplantation.

[Pneumococcal peritonitis in an adult. Report of a case].

A case report is presented of primary pneumococcal peritonitis, a disease rare in the adult. The etiology, differential diagnosis and therapy are discussed and the literature is reviewed. The authors believe that laparotomy should be performed in the case of acute abdomen with diffuse peritonitis, even if pneumococcal peritonitis is suspected.
