[A rare case of sigmoidoduodenal neoplastic fistula (author's transl)].

The clinical case of a patient with sigmoidoduodenal neoplastic fistula is taken as the starting-point for a review of the relevant literature. The great rarity of fistulisation of a sigmoid tumour of the 4th portion of the duodenum is stressed. A clinical definition of the disease is followed by a discussion of the various methods of surgical treatment, with emphasis on the problem presented by reconstruction of the duodenum owing to its anatomosurgical difficulties.

Mortality and morbidity in a pulp and a paper mill in the United States: a ten-year follow-up.

Two hundred and seventy-one men seen in 1963, who worked in a pulp and a paper mill, were followed up ten years later, in 1973. Death certificates were obtained for those who died. There did not appear to be any increased mortality in the group, nor was there any increased specific cause of death. A morbidity study of 200 men seen at both times did not show any differences in respiratory symptoms or prevalence of chronic non-specific respiratory disease. Analysis of pulmonary function showed little, if any, difference between groups. Analysis of retired, deceased, and still-working categories did suggest that exposures to Cl2 or SO2 might have a slight adverse effect on pulmonary function.

[Preliminary study of ultrastructural changes of the gastric mucosa due to cholecysto-gastrostomy. Experimental research].

After reviewing the literature on anatomo-histological lesions of the gastric mucosa in so-called "biliary reflux gastritis", the Authors undertook an experimental study of ultrastructural alterations of the gastric mucosa after cholecysto-gastrostomy operation conducted in the dog. In this preliminary note they report the alterations observed 60 days after the operation and consider it necessary to continue observations for a longer space of time after the operation.

[Anastomosis of the thoracic duct and the esophagus in surgical treatment of cholestasis. Experimental research].

After brief recall of the pathophysiology of cholestasis, the authors describe a technic of internal drainage of lymph from the thoracic duct by an indirect anastomosis created surgically between the latter and the esophaghus. They conclude that the procedure definitely solves certain symptomatologic aspects of cholestasis, but has no effects on the underlying anatomopathological lesion, which does not regress once established.

Chronic nonspecific respiratory disease in Berlin, New Hampshire, 1967 to 1973. A further follow-up study.

The 1967 sample of Berlin, New Hampshire was resurveyed in 1973 by means of a standard questionnaire on respiratory symptoms and by simple tests of pulmonary function. Measurements of the levels of air pollution showed a decrease in the number of suspended particulates and an increase in the concentration of sulfation. These values were close to the Federal Primary Standard. No differences in respiratory symptoms, prevalences of chronic, nonspecific respiratory disease, or pulmonary function were detected. Within the limitations of this study, we concluded that the Federal Primary Standards for sulfur dioxide and total suspended particulates are probably adequate to protect the public.

Colorectal surgery: short-term prophylaxis with clindamycin plus aztreonam or gentamicin.

A randomized study was conducted to compare the effectiveness of aztreonam plus clindamycin with that of gentamicin plus clindamycin for prophylaxis of infection following colorectal surgery. A total of 138 patients undergoing elective colorectal surgery were randomized to treatment with clindamycin (600 mg) plus either aztreonam (1 g) or gentamicin (80 mg) 30 minutes before and 8 and 16 hours after surgery. The study included 122 patients (88.4%) with colorectal carcinoma. Samples from the abdominal cavity and from the subcutaneous tissues were taken for bacteriologic study. All samples from the abdominal cavity yielded microorganisms; both aerobic and anaerobic bacteria were isolated. Wound infections occurred in eight patients (12.1%) in the aztreonam group and in 12 patients (16.7%) in the gentamicin group. Escherichia coli, Bacteroides species, enterococci, and staphylococci were isolated most frequently from wounds and were often isolated from bacteriologic samples from the abdominal cavity of the same patients. The incidence of septic complications reflected the extent of nutritional and immunologic impairment. No significant differences were found between groups in the rate of urinary tract or lower respiratory tract infections. Aztreonam/clindamycin appears to be a valid alternative to gentamicin/clindamycin for the prophylaxis of infections following colorectal surgery.

Aztreonam versus gentamicin for short-term prophylaxis in biliary and gastric surgery.

Short-term antibiotic prophylaxis was studied in 80 patients undergoing biliary or gastric surgery. The patients were randomized to receive 1 g of aztreonam or 80 mg of gentamicin intravenously 30 minutes before surgery and 8 and 16 hours after surgery. Of samples taken from the abdominal cavity for bacteriologic study, 53% were culture positive. Wound infections developed in two (4.5%) of 44 patients receiving aztreonam and in seven (19.4%) of 36 patients treated with gentamicin. Staphylococcus epidermidis and Enterobacter species were isolated from sites of wound infection in the aztreonam group; Escherichia coli (two isolates), Pseudomonas aeruginosa (two isolates), Enterobacter species, Klebsiella species, Enterococcus faecalis, and Aeromonas hydrophila were isolated from the gentamicin group. Our data indicate that aztreonam is safe and effective for the prevention of infections following biliary and gastric surgery.

Evaluation of the prognostic accuracy of Astler-Coller's and Jass' classifications of colorectal cancer.

AIM: The study aim was to determine whether the Jass classification is superior to that of Astler-Coller (modification of Dukes' stage) in determining prognosis of patients treated for colorectal carcinoma. STUDY DESIGN: The authors used Jass' classification to restage 263 patients who had undergone radical colorectal surgery and classified according to Astler-Coller. RESULTS: The results revealed that: 1) Astler-Coller's classification enables more accurate selection of patient groups where life expectancy can be predicted; 2) Jass' classification enables statistically significant (P <0.05) improved prognostic discrimination of Astler-Coller's B2 patients, for which the probability of nonrecurrence of the disease is around 60%. CONCLUSIONS: Although Astler-Coller's classification is still valid, Jass' classification is useful for the prognostic discrimination of Astler-Coller's B2 patients.

A new alternative technique to preserve native flow, for continuous hepatic artery chemotherapy, in presence of a right hepatic artery arising from superior mesenteric artery.

A new alternative technique for regional perfusion chemotherapy in the presence of a right hepatic artery arising from the superior mesenteric artery is described. The cystic artery branch of the right hepatic artery and the gastroduodenal artery can be used to place two catheters and thus apply two implantable systems. This risk-free, straightforward technique preserves native flow and achieves homogeneous distribution of the chemotherapeutic agent.

Giant esophageal polyp: a rare and benign neoplasm.

Giant esophageal polyp is a very rare neoplasm, usually benign but often demanding both for diagnostic and/or therapeutical procedures and for dramatic symptomatologic onset in the patient (regurgitation and asphyxia). The authors present a brief clinical report of a patient with a 20 cm.-long esophageal polyp removed by left lateral cervicotomy and esophagotomy for 8 cm. below the upper esophageal sphincter (histologic examinations showed a pedicled polypoid fibrolipoma with a remarkable presence of myxoid and vascular components). The authors also describe diagnostic and therapeutic methods to manage this rare disease and they gave a brief review of recent literature.

Totally implantable venous access device inserted during major abdominal operations for cancer. A new technique.

Totally implantable venous access devices are usually implanted by surgical cut-down technique or by percutaneous approach, after a first surgical procedure. The authors describe a new surgical approach utilizing the right gonadal vein or the vena cava for totally implantable venous access device placement in patients submitted to major digestive surgical procedures for tumors. This new surgical approach allows one to avoid a second operative procedure.

Multimodal therapy of hepatocarcinoma: personal experience on 90 cases.

BACKGROUND/AIMS: In recent years, surgical and non-surgical options have been developed in the treatment of hepatocellular carcinoma in cirrhotic patients. We review our personal series from 1995-1999, in order to assess the choice of treatment. METHODOLOGY: Of 90 cases of hepatocellular carcinoma observed in the years 1995-1999, 15 underwent curative resective surgery; in 42 cases TAE, PEI or RITA were utilized (9 of them as multimodal therapy). In the remaining 33 patients any kind of therapy was scheduled. RESULTS: The mean survival of the 15 resected patients was 18 months, non-statistically better than RITA survival, compared by Log-Rank test. Perioperative mortality calculated in all procedures was 5.2% (2 pts surgery, 1 pt TAE). CONCLUSIONS: The high percentage of not treated hepatocellular carcinomas in our series is generally due to large tumor size diagnosed in advanced Child's stage. PEI, TAE and RITA have to be considered effective and safe for palliation for HCCs. However, surgical resection represents the curative therapy in selected cirrhotic patients affected by HCC.

Stress of routine follow-up in colorectal cancer operated patients.

Postoperative follow-up is the logical consequence of cancer treatment, but colorectal cancer follow-up does not achieve all its goals. These unfavourable findings induced us to assess whether follow-up also causes negative psychological stress in our colorectal cancer patients. In this trial 100 colorectal cancer follow-up patients were asked to compile three questionnaires: 1) the McGil Pain Questionnaires; 2) Profile of Mood Status; and 3) Locus of Control. The questionnaires were handed to the patients at follow-up and were compiled immediately. In addition, the patients were asked to answer the firsts two tests spontaneously 30 days after follow-up and mail the questionnaires. Our results showed that only 41% of the patients complied the tests 30 days after follow-up. The scores for pain and mood disorders were greater in women, especially during the "before follow-up" period. The third test revealed a prevalence of subjects with internal-type reinforcement. Our data revealed that: 1) patients tend to repress the problem; 2) women are affected by greater stress and anxiety; 3) subjects with internal-type reinforcement have a positive attitude during follow-up and this enables the ego to bear the anguish, process it and dilute it to anxiety, thus favouring future life experiences.
