Laparoscopic abdominal observation method without anesthesia for preventing unnecessary second-look procedures: short report.

Second-look operations after massive intestinal resections secondary to mesenterovascular occlusion are a frequent practice. In about one half of patients who undergo second-look procedures, no intraabdominal intervention is necessary. We present a laparoscopic abdominal observation method to prevent unnecessary laparotomies. In the first operation, two laparoscopic trocars, 5 and 10 mm in diameter, were left in the abdominal wall. After an appropriate time interval, the abdomen was explored laparoscopically through these trocars without anesthesia. If obvious intestinal gangrene and anastomotic leaks were observed laparoscopically, the patients were reoperated on while under general anesthesia; otherwise, the procedure was terminated with removal of the trocars. This method was performed on six patients. Unnecessary relaparotomies were prevented in four patients; intestinal gangrene and anastomotic leaks were not missed in the remaining two patients. A larger patient sample is needed to assess the advantages of this method in preventing unnecessary laparotomies.

Observation of bacteria and fungi in infected root canals and dentinal tubules by SEM.

The aim of this study was to observe the root canal flora and possible penetration of microorganisms into dentinal tubules in teeth with necrotic pulps. Ten infected maxillary and mandibular molars with periapical lesions were extracted and fixed in 2.5% phosphate-buffered glutaraldehyde solution for nine days. After separation from the crowns, longitudinal grooves were cut in the roots, and they were split into two halves. The specimens were prepared for SEM. The root canals and the dentinal tubules of the fractured dentin were scanned systematically from the cervical to the apical area of the root. Cocci and rods were seen in 6 specimens. Penetration of bacteria into the dentinal tubules ranged from 10 to 150 microns. In 4 specimens, the root canals were heavily invaded by yeasts. The antimicrobial effect of routinely used endodontic disinfectants also on yeasts may be considered in persistent root canal infections.

A modified technique for performing anterior gastropexy in Stamm gastrostomies.

We describe herein a new modified technique for performing the anterior gastropexy step of the Stamm gastrostomy procedure. In this method, anterior gastropexy was carried out with four 2-0 silk or propylene sutures. These sutures were secured through the whole layer of the abdominal wall from out to within. Then, after passing the seromuscular layer of stomach, they return to skin through the abdominal wall from within to out and tied over the skin surface. This modified technique which provided better exposure and an excellent seal of the stomach and parietal peritoneum, was successfully performed on 23 patients, none of whom developed any peritoneal leakage and peritonitis. The only complications that arose were wound infection in one case and skin excoriation in two others, and these were easily managed.

Complications of 867 thyroidectomies performed in a region of endemic goiter in Turkey.

This article aims to define the incidence of complications in 867 thyroidectomies performed by residents with attending surgeons' supervision as part of a training programme, in a region of endemic goiter. Seven hundred and nine patients were female and 158 were male. The age of the patients ranged between 6 and 76 and mean age was 32.5. Cases were divided into two groups according to their disease nature. Group 1 included 805 patients with nodular colloidal goiter (NCG) and adenomas. The remaining 62 cases, 25 with recurrence of goiter (RG), 21 with thyroid malignancy (TM) and 16 with thyroiditis formed group 2. While the overall complication rate was 11.3% (93 cases) in group 1, it was 20.9% (13 cases) in group 2. The mortality rate was zero in both groups. The incidence of complications of 867 thyroidectomies performed by residents with the attending surgeons' supervision was within acceptable limits especially as far as group 1 was concerned. However we suggested that attending surgeons themselves, disregarding residents training, should perform the operation in special cases such as recurrent goiters, thyroid carcinomas with positive regional lymph nodes and thyroiditis with regional adhesions.
