Endoscopic thyroidectomy performed via the precordial approach leaves no scarring of the neck, and thus provided excellent results from a cosmetic viewpoint. We applied this technique to perform subtotal thyroidectomy in 12 patients with Graves' disease. Three trocars were inserted in the precordial region, and endoscopic surgery was performed with carbon dioxide insufflation. Vessel management and thyroidectomy were carried out using ultrasonic coagulation devices. The mean operative time was 259.8 min, and the mean blood loss was 90.2ml. There were no postoperative complications such as subcutaneous emphysema or hemorrhage, although hypoparathyroidism and recurrent laryngeal nerve paralysis occurred in one patient. Cosmetically esthetic results were achieved in all patients. These findings indicate that this surgical technique represents an effective method of treating Graves' disease that provides excellent cosmetic results.

Background: While intussusception is relatively common in children, it is rare in adults. Methods: We retrospectively reviewed the records of all patients older than 18 years with the diagnosis of intussusception between 1981 and 2001. Results: Eleven patients with surgically or endoscopically proven intussusception were encountered at the University-affiliated emergency center. The patients ranged in age from 19 to 88 years with a mean age of 45 years. Males predominated by a ratio of 7:4. Most patients (82%) presented with symptoms of bowel obstruction. The mean duration of symptoms was 4.5 days with a range of 4 h to 25 days. Correct pre-treatment diagnosis was made in 82% of the patients using abdominal ultrasonography and computed tomography (CT). The causes of intussusception were organic lesions in 64% of the patients, postoperative in 18% and idiopathic in 18%, respectively. 73% of patients had emergency operations, and an attempt at nonoperative reduction was performed and completed successfully in 3 patients with ileo-colic or colonic type of intussusception. There have been no cases of morbidity or mortality in our series and no recurrence has occurred up to the present time. Conclusions: Abdominal ultrasonography and CT were effective tools for the diagnosis of intussusception. Patients with ileo-colic and colonic intussusception without malignant lesions could be good candidates for nonoperative reduction prior to definitive surgery.

Pneumoperitoneum (PP) is usually the result of perforation of the gastrointestinal (GI) tract with associated peritonitis. However, other rare causes, including spontaneous PP incidental to intrathoracic, intra-abdominal, gynecologic, and miscellaneous other origins not associated with a perforated GI tract have been described in the literature. Six cases of PP without any perforated GI tract are reported. Three patients with generalized peritonitis underwent exploratory laparotomy or laparoscopy when clinical examinations suggested an acute abdomen. At surgical procedure, perforated pyometra, perforated liver abscess and a ruptured necrotic lesion of a liver metastasis were documented in these patients, respectively. We also saw 3 PP patients not associated with peritonitis. Two patients with PP caused by pneumatosis cystoides intestinalis were encountered, 1 was managed conservatively and the other received diagnostic laparoscopy. A patient in whom pneumomediastinum and pneumoretroperitoneum were accompanied by PP caused by an alveolar rupture based on decreased pulmonary compliance due to malnutrition was managed conservatively. The history of the patient and knowledge of the less frequent causes of PP can possibly contribute towards refraining from exploratory laparotomy in the absence of peritonitis.

Laparoscopic intervention offers better results in the management of patients with blunt abdominal trauma and isolated bowel rupture.

The diagnosis and treatment of internal abdominal hernia usually require laparotomy. We report a case of preoperative diagnosis and laparoscopic repair of paracecal hernia. A 90-year-old woman was referred with features of a well-established small bowel obstruction (SBO). Computed tomography and a small bowel contrast examination showed a paracecal hernia. With the patient under general anesthesia, laparoscopic surgery was carried out with the use of pneumoperitoneum, and an easy reduction of the incarcerated intestinal loop was achieved by gentle traction of the intestine. The bowel was assessed for viability and showed no evidence of nonviability. The abnormal orifice in the paracecal region was observed. The orifice was closed with 3-0 PDS II (polydiaxonone) sutures laparoscopically. A laparotomy was avoided, and the patient recovered without significant complications. We conclude that laparoscopy can play a useful role in the treatment of internal hernia causing SBO when an obstructive lesion has been detected and decompression accomplished preoperatively.
