Use of greater omentum in thoracic onco-surgery.

BACKGROUND: Omentum is well known for its immunocompetence and good blood supply; and therefore, is being used in various complex thoracic procedures. Specially, in situations when staplers, sealants and total parenteral nutrition may not be used because of financial constraints, omentum may prove very helpful in preventing post-operative fatal complications. METHODS: A retrospective review of 61 patients was undertaken. Patients were categorized into two groups. In group I, omentum was sutured to the anastomosis for prophylaxis of leak from gastro-oesophagectomy after radical surgery for cancer of cardia and oesophagus. In group II, it was used for therapeutic purpose, to control diffuse air leak from lung parenchyma after chest wall and invaded lung resection for malignant chest wall tumours (subgroup A) and treatment of post pneumonectomy bronchopleural fistula for NSCLC of right lung (subgroup B). Gastro-oesophagectomy, closure of bronchial stump and suturing of lung parenchyma after wedge resection was done with manual suturing technique only. RESULTS: Group I: There were 57 patients with the diagnosis of cancer of cardia and oesophagus, who underwent radical surgery. Transthoracic approach was used in 96.5% patients, whereas 3.5% patients underwent transhiatal resection. Anastomotic level was located in chest in 68.4% and in neck in 31.6% patients. The leakage rate was 5.4%. Group II: There were three patients in subgroup A, all with lesions located in left side of chest wall. There was one patient in subgroup B. Chest tube was removed after a mean time of 2 days and after 4 days in subgroup A and B, respectively. There was 1 mortality (1.6%) secondary to chylothorax. CONCLUSION: Use of pedicled omentum appears to be a very simple technique to prevent the anastomotic leak after radical surgery for cancer of cardia and oesophagus, and to seal the diffuse parenchymal pulmonary leak after various procedures in thorax.

Characteristics of women having abortion in China.

A pre-coded, closed response questionnaire was administered to women at abortion clinic sites in August 1985. The convenience sample was comprised of 1200 women, 200 samples in both Chengdu and the Lianshan Yi Autonomous Region in Sichuan Province, 400 in Nanjing and Jiangsu Province, and 400 in the municipality of Shanghai. The women were interviewed by physicians as part of the women's intake medical history. The sample yielded 574 respondents who were urban and 624 who were rural. The number of previous abortions reported ranged from 0 to 5. Nearly half of the abortion recipients had had at least one prior abortion and 18% had had two or more prior abortions. Education, age, marriage duration and residence have apparent effect on abortion order. The urban respondents reported an average of 1.08 children vs 1.60 children for the rural respondents. Approximately 72% of the respondents claimed to have been using a contraceptive method at the time they became pregnant. The most commonly used method was the IUD (41.6%), followed by the pill (21.3%) and the condom only (16.5%). Residence appeared to be the greatest factor determining the type of contraceptive methods. The data presented here are limited and cannot be generalized to the larger population. However, they do shed some light on the contraception characteristics of a group of women who undergo abortion procedures in China. Their response to questions to contracepting behavior prior to abortion suggests that the problem, in part, is behavioral. For example after the expulsion of the IUD, no other method was substituted to avert pregnancy. In order to alleviate the problem of contraceptive failure, and subsequent abortion, there are policy as well as training and education implications for the state.
