Disconnection of the ampulla of Vater: a new technique for reconstruction.
No full textWe report the case of a 42 year-old patient who had undergone gastric resection
and Billroth I reconstruction for a duodenal ulcer 15 years earlier. The patient
was admitted to our Department for a high output biliopancreatic fistula which
developed after another gastric resection with Billroth II reconstruction which
was performed for a peptic stricture of the gastroduodenal anastomosis. At
laparotomy, a complete disconnection of the ampulla of Vater was found, with the
duodenal stump oversewn 5 cm distally to the papillary area. After plasty of the
biliary and pancreatic ducts, a direct anastomosis between the new ampulla and a
Roux-en-Y jejunal loop was performed. The post-operative course was uneventful.
The details of the surgical technique are reported

Videothoracoscopic enucleation of esophageal leiomyoma.
No full textA new thoracoscopic technique to enucleate esophageal leiomyomas is described.
The procedure has been successfully performed in 3 patients. All patients
benefited by this new surgical approach due to the decreased operative trauma,
reduced postoperative pain, quick recovery, and minute skin scars. Although
further clinical experience and longer periods of follow-up are needed to
evaluate the full benefits and limits of this new access, the early results of
the thoracoscopic approach are promising

No full textThoracoscopic removal of benign tumours of the oesophagus.
No full textThoracoscopic excision of an oesophageal leiomyoma was successfully performed in
4 patients. The tumours were enucleated easily without intraoperative
complication. A patient in whom the muscular layer was not sutured after removal
of the myoma presented with a pseudo-diverticulum one year after the operation
and required a thoracotomy for resection. This new procedure which reduces the
operative trauma and postoperative pain and allows quick recovery, is describe
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
