Functional evaluation of tracheal stenosis before and after surgical management.

14 patients affected by tracheal stenosis resulting from assisted ventilation underwent a tracheal resection (n = 12) or dilatation (n = 2). Lung function tests were performed before and after surgical treatment. Prior to surgery, we observed a significant increase in airway resistance (Raw) in all subjects and a negative exponential relationship between Raw and FEV1/VC. Expiratory flows were also reduced with an increase in FEV1/PEFR ratios. After surgical correction of the stenosis, Raw normalized in 10 out of 14 subjects. The observed changes were more significant than for the other functional tests. After surgery, the patient's follow-up with Raw allowed the diagnosis of recurrent stenosis in 4 subjects lacking significant clinical symptoms. We conclude that measurement of Raw helps the clinical diagnosis and the appreciation of the possible changes in airway permeability after the surgical procedure.

Laparoscopic highly selective vagotomy.

BACKGROUND/AIMS: Ten percent of our population has had a gastroduodenal ulcer. Medical treatment heals ulcers in 90% of the cases but they recur in 50-70% of the patients. We present a proposal of surgical treatment for patients with recurrent ulcer after a long-term medical treatment or whose ulcer reappears as soon as medical treatment ceases. METHODOLOGY: Thirty-three patients underwent highly selective vagotomy (HSV) laparoscopic between April 1992 and March 1993. There were 26 male patients and 7 female patients aged 19-65 years (mean age: 38 years). Twenty-six patients were operated electively and preliminary medical treatment lasted an average 5.4 years (range: 0.5-26 years) and the disease had lasted 1-30 years (mean duration: 8.4 years). For patients with a chronic peptic ulcer disease, pre-operative assessment involved a recent gastroscopy, isotopic gastric study and a selection test. RESULTS: HSV proved feasible in 100% of the cases in spite of a history of previous surgery and peritonitis in patients with a perforated ulcer. There were neither conversions nor intra-operative complications. There was no mortality or morbidity. The mean hospital stay was 2 days (range: 1-5 days) for selectively operated patients and 7 days (range: 6-10 days) for patients operated for a perforated ulcer. Twenty-two patients were rated Visick I and II and 3 with Visick III after re-examining. The BAO had decreased by 61% to 89% and the MAO by 60% to 80%. CONCLUSIONS: The treatment of choice for gastro-duodenal ulcer is highly selective vagotomy. The laparoscopic approach shortens the hospital stay and improves patient's comfort.

Isolated perforations of the small bowel from blunt abdominal trauma. Report of two cases and review of the literature.

On account of two recent cases, the authors present a review of the literature of small bowel isolated perforations following blunt abdominal trauma. Although these injuries are quite rare and their management relatively easy, the diagnostic approach is often hazardous and may lengthen the operative delay, worsening morbidity and mortality. The authors review the various physiopathological mechanisms (deceleration, crushing and rupture phenomena) responsible for small bowel perforations, as well as the predisposing factors. They emphasize the multiple pitfalls of the diagnosis and try, through a study of the literature, to establish systematic guidelines. The advantages and deficiencies of the various complementary investigations are discussed. The authors conclude with indications of conservative treatments and segmentary enterectomies respectively.

Intestinal obstruction and portal vein gas embolism.

The presence of hepatic portal vein gas is the consequence of invasion by anaerobic bacteria originating from an intestinal tract lesion. Although this phenomenon is rare, it may result from several common intestinal pathologies. The prognosis, despite intensive treatment, is often very poor. The authors report a case associated with bowel necrosis resulting from intestinal band.

Laparoscopic Nissen fundoplication: laparoscopic dissection technique and results.

BACKGROUND/AIMS: Proton Pump inhibitors and laparoscopic techniques have had a dramatic impact on the therapy of gastroesophageal reflux disease. These techniques have introduced new complications associated with the treatment. This study compares the results of a laparoscopic Nissen fundoplication with life-long proton pump inhibitor treatment. MATERIALS AND METHODS: Between May 1991 and February 1996, 274 patients were treated by laparoscopic Nissen fundoplication (LNF). Two hundred twenty-four patients were included in this prospective study. Thirteen patients presented stage V esophagitis (Barrett); 4 had esophagitis stage IV; 16 had stage III, 181 had stage II and 11 had stage I. Five trocars were needed for the operation. After mobilization of the greater curvature, a fundic wrap of 5 cm was created and fixed on the esophagus. RESULTS: Median operating time was 60 min (39-300). There were 5 perioperative complications (a gastric perforation, three pleural perforations, and one liver laceration treated by coagulation). Three conversions to laparotomy were necessary. There were 4 early complications: two pulmonary infections and two re-operations; one case of wrap necrosis with peritonitis, and one case of small bowel perforation. Gastroscopy was performed in 133 cases. The esophagus was normal in 121 cases, an esophagitis stage I was present in 9, esophagitis stage II in 2, esophagitis stage III in one. Median lower esophageal sphincter pressure was 10 mmHg (2.9-30) preoperatively and 19 mmHg (9-40) post-operatively. Median reflux time was 10% (0-65) preoperatively and 1% (0-38) post-operatively. One hundred fifty-four patients were interviewed with a median follow up of 30 months (1-58). One hundred thirty patients were Visick I, 11 Visick II, 8 Visick III and 5 patients needed re-operation; three reoperations because of dysphagia, 1 because of epigastric pain and 1 for heartburn recurrence. CONCLUSIONS: From these results, we conclude that LNF seems to be an attractive alternative to long term medical treatment.
