Preoperative laparoscopy in management of patients with carcinoma of the esophagus and of the esophagogastric junction.

BACKGROUND AND OBJECTIVES: Adequate preoperative staging of patients with esophageal and cardia carcinoma offers the potential for a rational choice of the therapy. The aim of this study was to assess the diagnostic value of laparoscopy compared to ultrasonography (US) and computed tomography (CT) in detecting intra-abdominal metastatic spread. METHODS: Between November 1995 and December 1996, 36 patients with adenocarcinoma of the cardia and 14 patients with squamous cell carcinoma of the lower third of the esophagus were studied with CT scan and US, followed by laparoscopy performed at the same session of planned surgical resection. Mean operative time of laparoscopy was 20 minutes (range 15-55 min). There was no mortality nor morbidity related to the laparoscopic procedure. RESULTS: Laparoscopy lead to a change of the therapeutic approach in five patients (10%): three patients with peritoneal carcinosis undetected at the imaging examinations, and one patient with advanced liver cirrhosis with signs of portal hypertension did not undergo resection; conversely, one patient with a liver hemangioma simulating a metastatic mass at CT/US underwent esophagogastric resection. Laparoscopy showed a higher sensitivity than US and CT in detecting peritoneal metastases (71% vs. 14% vs. 14%, respectively), macroscopic nodal metastases (78% vs. 11% vs. 55%), and liver metastases (86% vs. 71%). CONCLUSIONS: Laparoscopy represents a safe and effective diagnostic procedure in the preoperative staging of esophageal and cardia carcinoma; it provides the potential to avoid unnecessary exploratory laparotomies and to select the most appropriate treatment.

Endoscopic ultrasonography for preoperative staging of esophageal carcinoma.

Endoscopic ultrasonography (EUS) is a relatively new diagnostic method to assess the extent and the depth of infiltration of esophageal carcinoma. Since October 1990, EUS was performed in 55 patients presenting with squamous-cell carcinoma of the esophagus, 40 of whom were operated on. The first 23 patients underwent EUS with an Olympus GF-2/EU-M2 echoendoscope with a 7.5-MHz transducer; the last 32 patients underwent EUS with an Olympus GF-3/EU-M3 instrument with a 7.5-12-MHz echoprobe. In 22 patients, the procedure was not completed because of the impossibility of passing through the neoplastic stenosis. The depth of infiltration (T parameter) was correctly defined by EUS in 36 of 40 patients (90%) compared with 50% of computed tomography (CT). The 12-MHz echoprobe yielded a global accuracy in staging T parameter of 94% compared to 82% of 7.5-MHz transducer. The lymph-node involvement (N parameter) was correctly classified by EUS in 20 of 23 patients (87%) compared with 39% by CT. EUS provides a high degree of accuracy in assessing the T and the N parameter in the staging of squamous-cell esophageal carcinoma. The major problem of the instrument is still the frequent impossibility of passing through the neoplastic stenosis.

[Right adrenal adenoma: laparoscopic exeresis].

The authors report the case of a non functioning adrenal adenoma, incidentally diagnosed and excised through a laparoscopic approach. Indications to adrenalectomy for such a pathological condition and surgical technique are reviewed and discussed. In consideration of the relatively rare disease and of the scant literature on minimally-invasive approach to right adrenalectomy, it seemed worth reporting this case and the technical skills performed to ease this operation through laparoscopy.

Ultrasonography of extremity lymphedema.

Ultrasonography of the extremities was performed in 91 patients with unilateral or bilateral peripheral lymphedema of the arms or legs. Linear 3.5 to 10 mHz ultrasonographic linear probes were used in accordance with standardized procedure. The data demonstrated a volumetric increase of the lymphedematous limb with increased thickness of both the subcutaneous and subfascial (muscular) compartments consistent with fibrosclerosis in both compartments with chronic disease. Whereas dermal thickening was minimal, subcutaneous and subfascial changes were more prominent in primary than secondary lymphedema. By providing information about the volumetric and structural alterations with chronic lymphedema, ultrasonography safely and simply supplements conventional and isotopic lymphography in assessing patients with chronic lymphedema.

[Horizontal gastroplasty in surgery for morbid obesity: an unjustified condemnation?].

Horizontal gastroplasty has been performed on 100 pathologically obese patients over the last nine years. In our series, the mean age was 39.3 +/- 8.2 years and the mean body weight was 120.8 +/- 19.6 kg. One year after surgery the average weight loss was 29.7 kg which corresponds to a reduction of 24.6% of the preoperative weight (BMI:-24%). After three years, the body weight stabilised, reaching a total weight reduction of 30.5% (BMI:-28.7%), corresponding to 36.8 kg. The incidence of complications directly related to surgery was generally acceptable. The absence of specific malabsorption problems, the low incidence of severe complications and the satisfactory weight loss induced and maintained make, in our opinion, horizontal gastroplasty one of the most suitable and effective interventions in the long-term management of morbid obesity.
