Can routine laparoscopy help to reduce the rate of explorative laparotomies for gastric cancer? Laparoscopy in gastric cancer.

1. Background We developed this surgical protocol about performing intraoperative laparoscopy for staging in every patient affected by stomach cancer. Sensitivity and specificity of intraoperative laparoscopy are compared with conventional preoperative staging techniques.2. Methods From January 1994 to June 1999, 83 patients affected by stomach cancer were accepted in our department: 12 patients (14.5%) were excluded from our study after the preoperative staging; in 71 patients (85.5%) an explorative laparoscopy as the first step of the operation was performed.3. Results Laparoscopy confirmed preoperative staging in 53 cases (74.6%), in 12 patients demonstrated an overstaging. Laparoscopy demonstrated in 6 patients unsuspected causes of unresectability.4. Conclusions When performed in patients affected by malignant neoplasm and declared resectable, intraoperative laparoscopy can demonstrate conditions not detectable by traditional preoperative investigations, consequently reducing to zero explorative laparotomies.

False radiographic appearance of a right bronchial stump following extended right pneumonectomy.

The authors describe three cases in which postoperative frontal chest radiographs following extended right pneumonectomy showed a right hilar lucency producing the false appearance of a residual main bronchus that is shown by additional studies to represent a dilated esophagus.

Endoscopic resection of esophageal lymphangioma incidentally discovered.

A pedunculated lymphangioma of the esophagus was unexpectedly discovered during an endoscopic investigation performed for epigastric pain in a patient affected by diabetic arteriopathy treated with antiplatelet drugs. The patient neither complained of dysphagia nor other symptoms related to the presence of the lymphangioma which therefore can be considered as an endoscopic "incidentaloma".The lesion was removed endoscopically and a follow up, 6 months later, showed no scar or recurrence.The authors present this case both for the extreme rarity of this lesion and for the evidence of low-medium grade dysplasia in the overlying mucosa, particularly since it is only case ever noted in literature.This aspect suggests that, even if malignant degeneration of these lesions has never been observed, their endoscopic removal is recommended. However, when endoscopic procedures are not feasible, thoracotomic surgical exeresis should be only considered for obstructing and symptomatic lesions; an accurate endoscopic and bioptic follow up can be useful for asymptomatic lesions.

The use of fiberoptic bronchoscopy during percutaneous dilatational tracheostomy with laryngeal mask.

UNLABELLED: The aim of our research is to evaluate the advantage by the combined use of fiberoptic bronchoscopy and laryngeal mask during the performance of percutaneous dilatational tracheostomy in an intensive care unit. PATIENTS: 16 adult patients who were candidates to middle-long term mechanical ventilation. ENVIRONMENT: Intensive Care Unit of a Community General Hospital. RESULTS: We experienced 3 minor complications (2 minor bleedings and 1 neck emphysema). Difficulties were found in 3 patients with particular anatomical conformation (obese patients with short neck and limited mobility of the cervical spine). CONCLUSION: The combined use of fiberoptic tracheo-bronchoscopy with the laryngeal mask permits a better endoscopic visualisation of the operatory field, providing a more secure and precise procedure.

Major thoracoscopic operations: pulmonary resection and mediastinal mass excision.

After the great success of laparoscopy in the field of abdominal surgery, the mini-invasive approach has opened interesting new possibilities in the field of thoracic surgery too. At present, in many centres, thoracoscopy is the surgical approach of choice for the treatment of recurrent pneumothorax, giant bullous lung disease, peripheral benign lesions. In very few centres a new phase is now starting, having the objective of verifying the validity of more complex thoracoscopic surgical operations. The authors describe their experience in performing major thoracoscopic operations such as excision of mediastinal masses and major pulmonary resections. The series includes 36 patients submitted to thoracoscopic excision of mediastinal masses and 113 patients submitted to video-thoracoscopic major pulmonary resections. Every kind of mediastinal lesion as well as every kind of major pulmonary resection was performed; the evidence of no intra-operative deaths confirms the possibility of a useful employment of the mini-invasive approach in this kind of surgery.

Videothoracoscopic operative staging for lung cancer.

The authors describe their experience in performing Videothoracoscopy as the first step of the operation in patients affected by lung cancer: they refer to this procedure as Videothoracoscopic Operative Staging (VOS). In 286 patients, already proposed for curative surgical resection on the basis of conventional staging, VOS was carried out in order to reach a conclusive judgement of resectability. VOS discovered unsuspected causes of inoperability in 17 patients (5.7%), while 269 patients underwent surgical operation but in 9 of them this consisted in an exploratory thoracotomy (ET). Furthermore, VOS allowed us to assess the operability of 11 patients in whom preoperative computed tomography (CT) had suggested unresectability but without providing a definitive judgement. Based on their experience the Authors conclude that VOS should be performed in every patient affected by lung cancer in order to obtain a more detailed staging and to reduce to a minimum the number of ETs. By using VOS it was possible to decrease the rate of exploratory thoracotomies to less than 4%.

Endoscopic treatment of postoperative external biliary fistula in a patient operated on for hepatic injury due to multiple trauma.

After surgery for hepatic injury as a result of blunt abdominal trauma from a motorcycle accident, an external biliary fistula developed in a young patient. The authors describe the rapid and complete healing of the fistula by use of a nasobiliary catheter. These findings emphasize the importance of endoscopic operative technique for postoperative and traumatic external biliary fistulas.

Videothoracoscopic staging and treatment of lung cancer.

Videothoracoscopy, routinely performed as the initial step of an operation, opens interesting opportunities for both the operative staging and treatment of lung cancer. Videosurgical maneuvers ensure thorough exploration of the cavity, thus avoiding unnecessary exploratory thoracotomies, confirming resectability of the lesion by open or, in selected cases, by a direct video-assisted approach. We report our experience of 155 patients submitted to videothoracoscopic operative staging between October 1991 and January 1994. Videothoracoscopic operative staging showed unresectability in 13 patients (8.3%) due to preoperatively unexpected (10 patients) or suspected conditions (3 patients). The remaining 142 patients were divided by staging of the lesion and general conditions into three groups. Group A consisted of 13 elderly patients with small peripheral tumor who could not tolerate lobectomy and who underwent thoracoscopic wedge resection. Group B consisted of 63 patients with peripheral clinical T1 N0 or T2 N0 tumor. Fifty-two lobectomies and 4 pneumonectomies were carried out thoracoscopically. Seven conversions to thoracotomy were necessary due to technical problems. The postoperative course was uneventful in 51, 5 had prolonged air leakage, and a bronchial fistula developed in 1 because of positive-pressure postoperative ventilation. Group C consisted of 66 patients with stage II or IIIa neoplasm. Thoracotomy after thoracoscopy proved unresectability in 4, whereas 62 were submitted to a radical pulmonary resection. In the literature the incidence of exploratory thoracotomies for conditions missed by preoperative staging still remains high. After adoption of videothoracoscopic operative staging we reported a 2.6% exploratory thoracotomy rate.(ABSTRACT TRUNCATED AT 250 WORDS)
