Surgical treatment of morbid obesity.

The classical indications for the surgical treatment of morbid obesity is weight of at least 50% (males) and 80% (females) over the ideal body weight, in patients between 14 and 55 years of age. These limits are now being extended both to less overweight patients and to patients over 55 years of age. Jejunoileal bypass is the treatment of choice for severely overweight patients in good general condition, allowing them to continue with their eating habits. Gastric bypass is indicated in elderly patients or in patients with previous liver diseases. It should not be performed in younger patients because of the irreversibility of the procedure. A careful postoperative long-term follow-up is necessary to prevent the complications associated with each type of operation.

Indications and results of the surgical treatment in Raynaud's phenomenon.

203 patients submitted in the last 20 years to surgery, first by Smithwick's sympathectomy, then by Adson's gangliectomy and lastly by Telford's gangliectomy, were controlled. The frequency of true Raynaud's disease is with time decreasing and is found today in the minority of the patients suffering from Raynaud's phenomenon and surgically treated. Immunological tests detect frequent associated autoimmune disorders to be treated before surgery. Surgical indication is today selective. For this reason long term results are improving: 90% of positive results in the last series against 73% and 60% respectively in the previous series.

[Treatment of peri-anal fistulas. A current problem].

This problem of the treatment of perianal fistulas is examined and current principles of correct, effective therapeutic conduct set out. The techniques available vary with the type of fistula and the school of proctology. The as yet controversial point revolves about the way and the extent of possible sphincteric section. 80 cases reported provide a basis for some practical considerations.

Pneumatosis cystoides intestinalis and jejunoileal bypass.

The authors present a case of pneumatosis cystoides intestinalis, observed by chance in a patient previously subjected to end-to-end jejunoileal bypass for severe obesity. Using their observation and the cases reported in the literature as a starting point, the authors discuss the etiopathogenetic and clinical aspects of the disease, and briefly indicate what is, at present considered the correct therapeutic approach.

[Pefloxacin + metronidazole versus netilmicin + metronidazole in the prevention of nosocomial infections in contaminated surgery. Pefloxacin Study Group].

Pefloxacin plus metronidazole versus netilmicin plus metronidazole in the prevention of nosocomial infections during contaminated surgery. Surgical prophylaxis is widely used in contaminated surgery, especially colorectal surgery. In this clinical trial the efficacy of pefloxacin 800 mg i.v. slow infusion associated to metronidazole 500 mg i.v. 1-2 hours before surgery and then metronidazole alone after 6 and 12 hours versus netilmicin 200 mg i.m. associated to metronidazole 500 mg i.v. 1-2 hours before surgery and then both after 6 and 12 hours were evaluated in 97 patients suffering by colorectal surgery. Efficacy of prophylaxis in patients was evaluated in terms of appearance of post-surgical infections (abdominal, urinary, respiratory and wound infections). In pefloxacin + metronidazole group (53 patients), two cases of wound infections (3.8%) and three cases of respiratory infections (5.8%) were observed. In netilmicin + metronidazole group (44 patients), two cases of wound infections (4.9%), three cases of urinary infections (7%), three cases of respiratory infections (7.5%) and one case of intra-abdominal infection were observed. Our data confirmed that in colorectal surgery, the association pefloxacin, drug with microbiological and pharmacokinetics characteristics suitable for prophylaxis + metronidazole, active against anaerobes pathogens, prevents post-surgical infections as well as a reference association (netilmicin + metronidazole), with the advantage of a single administration.
