[Perforated diverticulitis of the colon: modalities of the surgical treatment].

A retrospective study was carried on 66 patients surgically treated for perforated diverticular colonic disease: 22 had acute phlegmon or pericolic abscess and underwent primary resection and anastomosis. Of the remaining 44 patients, who had multiple pericolic and/or pelvic abscesses, or generalized peritonitis, in 30 cases the Hartmann procedure was used, 6 underwent Mikulicz operation, while drainage with proximal colostomy was performed in 5 cases, and simple suture and drainage in the last 3 cases. Operative mortality was 18.2%. Mortality rate was higher in patients treated by colostomy and drainage. The Hartmann procedure and resection-anastomosis patients had a mortality rate of 23.3% and 4.4% respectively. No mortality was registered among patients treated with suture and drainage.

[Leiomyosarcoma in jejunal diverticulum. A case report and review of the literature].

The Authors describe a case of double jejunal diverticulum, characterized by the presence of a leiomyosarcoma in one diverticulum and ectopic pancreatic mucosa in the other. The rarity of the occurrence of a leiomyosarcoma in the diverticular area is outlined; only few cases have been reported in Literature, excluding those originating, from Meckel's diverticulum. Barium X-rays of the small intestine allowed the neoplasia to be discovered, while an Echo-Color-Doppler examination suggested the histological type given the high vascularization typical of leiomyosarcomas.

Lung cancer in young patients.

Despite the increasing frequency of lung cancer, the percentage occurring in young patients is very low (1.3-5.5% of all lung cancers). In 1992, of the 78,124 cases observed in Italy, 2.8% involved patients under 40 years of age. We reviewed a series of 800 patients with histologically proven lung cancer, candidates to a long-term follow-up. Of these, 23 (2.9%) were under 40 years of age, with a low male/female ratio (1.87:1). Fifty-two percent were smokers and 82.6% presented symptoms as the time of diagnosis. The most frequent histologic types were adenocarcinoma and large-cell type, which carried a better outcome (10-year survival of 28.5%) than epidermoid and small-cell types (p = 0.013). These tumors detected in 13% and 17.4% of cases, were unresectable (except for one epidermoid carcinoma), with a survival expectancy of 0% at two years. Considering all patients, resection was possible in nine cases, being curative in seven, with an overall 10-year survival rate of 44.4% (p = 0.002 vs non-resected patients). Stage I-II had the best prognosis with a 10-year survival rate of 80% (p = 0.022 vs resected stage III-IV). Patients undergoing primary chemotherapy and/or radiotherapy had the worst prognosis with no survivors at 30 months. In young patients clinical and pathological parameters had almost the same distribution except for sex and histologic type and offered almost the same survival probability as in patients over 40 years of age. When prognostic findings were tested by univariate analysis, only resectability was found to have an independent favourable impact on survival (hazard risk: 7.47; 95% confidence interval: 1.50-37.14).

Ventilation-perfusion mismatching as prognostic factor of respiratory failure after pulmonary resection.

This paper reports the results of a retrospective study undertaken to assess the reliability of regional ventilation-perfusion pulmonary scanning in predicting the remaining respiratory function (pFEV1), and the early and long-term outcome of 33 patients with chronic airways disease, submitted to pulmonary resection at the 1st Department of Surgery. All patients had been diagnosed as resectable with the traditional tools and had a traditional pFEV1 (tpFEV1) greater than 800 ml. All pFEV1 were re-calculated (npFEV1) with our new formula which also includes as lost for function all lung areas not to be resected with V/Q mismatching. Normal perfusion and ventilation distribution was found in 24.2% of patients in the lesion area and in 33.3% in the remaining pulmonary areas. An impairment of perfusion was observed in the lesion area in 72.7% of patients, in the remaining areas in 48.4%. An impairment of ventilation was observed in the same regions in 66.6% and 48.5% of patients, respectively. Abnormality in ventilation/perfusion matching occurred in the lesion area in 15.2% of cases, in the ipsilateral lung areas in 18.2%, in the contralateral lung in 48.4% of cases. In predicting postoperative FEV1, and early and long-term mortality among our resectable patients, the tpFEV1 showed an accuracy of 91%, an index of resectability of 93.7%, of unresectability of 0%. Our npFEV1 reached an accuracy of 94.4%, an index of resectability of 100% and an index of unresectability of 66.7%.

Results of surgical treatment of stage IIIA non-small cell lung cancer.

From 1975 to 1993, 665 patients with non-small cell lung carcinoma (NSCLC) were studied in our Unit. Of the 55 stage IIIA patients submitted to resection, 50 were followed-up in order to evaluate the effectiveness of surgery and to identify which variables had a prognostic impact on survival. The expectancy of survival at 3,5 and 10 years was 31.7, 19.5 and 13.7%, respectively. When the analysis was limited to N2 patients, 3,5- and 10-year survival rates were 20.9, 14 and 7%, respectively. Regarding the "TN" factor, the T3N0 subset presented the highest expected survival (24.8 and 18.6% at 5 and 10 years). With regard to the "T3" factor and type of surgery, peripheral tumors submitted to en bloc resection of the chest wall showed the best 5-year survival rate (42.9%), whereas extrapleural resections--even for tumors confined to the parietal pleura--showed a 5-year survival rate of 14.3%. A slightly higher risk of death was observed in tumors originating in the superior sulcus (SST). No patients with mediastinal pleura and pericardium involvement survived more than 34 months. With univariate analysis, "N2" was the variable most significantly associated with a negative prognosis when related to T3 (T3N2 vs T3N0 0.025 < P < 0.05) or non-epidermoid tumor (no survivors at 3 years; N2 epidermoid vs N2 non-epidermoid tumor P < 0.05). Applying multivariate analysis, epidermoid cell type, even if exclusively for N2 tumors, was an independent prognostic factor, showing a favorable impact on survival expectancy (27.8% at 90 months).

Local and/or distant recurrences in T1-2/N0-1 non-small cell lung cancer.

Data from a series of 181 patients subjected to long-term follow-up after surgical resection for non-small cell stage I and II lung cancer were analyzed to evaluate the statistical incidence and the prognostic factors of recurrence. The recurrence rate/year was particularly high in the first 2 years after surgery: the 2-year recurrence rate was 35.1% in stage I tumors and 51.8% in stage II, whereas the 5- and 7-year recurrence rates were 46.1 and 55.9% and 65.8 and 70.7%, respectively, for the same groups. Recurrences were observed more frequently in non-epidermoid carcinomas with multiple nodules (100% at 5 years) and in carcinomas classified as stage II (70.7% at 5-7 years), particularly when defined as adenocarcinoma (100% at 3 years). In the overall recurrence rate we observed no significant difference dependent on the type of resection even though limited segmental or wedge resection appeared to be related to a higher risk rate (true recurrence rate ratio: 0.6). Over two-thirds of the first observed recurrences were located at a distant site, with a slightly higher incidence of non-epidermoid carcinoma (72.5%). Isolated local recurrence mostly occurred in epidermoid carcinoma (47.6%). The most frequent sites of recurrence were the brain, bone and mediastinum. On multivariate analysis, independently significant adverse prognostic factors regarding the recurrence incidence were: tumor size greater than 3 cm, bronchial or hilar lymph node involvement, tumor histologically defined as adenocarcinoma, and the presence of satellite nodules.

The usefulness of biliary drainage for restoring liver function in obstructive jaundice.

In eighty patients with obstructive jaundice treated with percutaneous or endoscopic drainage, the results of biochemical liver-function tests (serum bilirubin, transaminase, gamma-glutamyl transferase, alkaline phosphatase, and albumin) were analyzed to evaluate the return of liver function after biliary decompression. Before decompression all the patients had increased serum concentrations of all the liver-function indicators measured. Conjugated bilirubin normalized within 7 days in 67.5% of the patients and within 14 days in 94.5%. The other serum responses normalized as follows: glutamic oxaloacetic transaminase (7 days in 45%, 14 days in 100%); glutamic pyruvic transaminase (7 days in 46.2%, 14 days in 100%); gamma-glutamyl transferase (7 days in 56.2%, 14 days in 89.1%); alkaline phosphatase (7 days in 52.5%, 14 days in 90.4%); and albumin (7 days in 100%, 14 days in 90.4%). The low mortality and morbidity rates in this series of patients with obstructive jaundice: 0% and 7% after endoscopic and 2.1% and 10.4% after percutaneous drainage suggest that biliary drainage has a valuable place in the preparation of jaundiced patients for surgery and in some cases provides a definitive intervention.

The role of surgery in stage IIIa non-small cell lung cancer. Surgery in IIIa NSCLC.

The authors have reviewed the records of 50 consecutive patients resected for stage IIIa non-small cell lung cancer and included in a long-term follow-up study at the 1st Department of Surgery, University of Rome "La Sapienza". Overall survival was 60-20-16.6-16.6% at 1-5-7-10 years with an incidence of recurrence and/or metastasis respectively of 56-80-85.6-85.6%. These percentages were not influenced by the histological type. Tumours with the best prognosis were those classified as T1N2 and T3N0 (7-year survival rate: 33.3 and 29.4% respectively). Tumours with the worst prognosis were those classified as T3N2 with the highest incidence of relapse after 6 months (T3N0 vs T3N2 0.01 < p < 0.025) and no survival after 3 years (T3N0 vs T3N2 0.005 < p < 0.01). Regarding T3 tumours, infiltration of mediastinal pleura or pericardium was a negative prognostic factor implying no survival at 30 months. Involvement of chest wall or parietal pleura showed better survival overall although not statistically significant (10-year survival rate: 37.4 vs 24% respectively).

Esophagocardiomyotomy with Dor gastroplasty in the treatment of esophageal achalasia.

Thirteen patients affected by achalasia of the esophagus, undergoing esophagocardiomyotomy with Dor gastroplasty, are reported. No postoperative deaths or complications occurred. Overall long-term results were satisfactory: excellent or good in 92.3% of cases, fair in 7.7%. Manometry after esophagocardiomyotomy as compared to preoperative assessment showed a decreased resting pressure in the esophageal body, in all patients in whom it was elevated, and the appearance of some peristaltic waves in 23.1% of them (3 patients). As for lower esophageal sphincter, some relaxation after deglutition was observed in one patient. The 24h pH monitoring showed signs of gastroesophageal reflux only in one patient. Based on the obtained results which compare well with those of the literature, the authors be believe that the procedure represents an effective treatment of esophageal achalasia.

Thymostimulin effect on the immune response in neoplastic patients submitted to surgical treatment.

We selected the data from performance status, disease state, skin tests, circulating lymphocytes and relative subsets, serum immunoglobulin classes to evaluate the immune response in 29 neoplastic patients treated with surgery and undergoing Thymostimulin administration during long term follow-up. Moderate drug intolerance was observed in 3 patients. After treatment lymphocyte count increase (41% mean increase) in 61.5% of cases; CD3, CD4, CD8, CD16 respectively 95-74-87-82% of cases; immunoglobulin classes in about 90% of cases. A clear-cut improvement of Karnofsky's index was observed in 34.6% of cases, worsening in 11.5%. A manifest improvement in the delayed hypersensitivity skin test resulted in 36% of cases. Most patients (85%) have shown signs of complete disease remission. Disease progression was observed only in 3 patients. There were no infections during this study.

Thymostimulin effect on the immune response in pulmonary carcinoma with or without surgical treatment.

Experience with 54 patients affected by pulmonary carcinoma treated or not with surgery and undergoing thymostimulin administration during long-term follow-up (70 mg i.m. every other day for 3 months), is reported. Drug intolerance was observed in 5.5% of cases. In patients who were able to complete the therapeutic cycle (50 cases) objective improvement of Performance Status was obtained in 46% of cases and subjective improvement in nearly 90%. The course of neoplastic disease showed definite progression (presence of local recurrence or distant metastasis) in 20% of cases, remission in 6%. No case of onset of pulmonary or extrapulmonary infections was observed. After treatment, a significant increase (between 24% and 108%) in blood parameters (circulation lymphocytes, CD3, CD4, CD8, CD16, IgG, IgA, IgM) was observed in 28-56% of cases. As for CD4 increase, this was accompanied by concomitantly positive Merieaux test in 44.5% of cases. Quiescence or complete remission has appeared to occur together with high CD16 values, progression with high CD8 and low CD16 values.
