    Egg-case diversity among dogfish, Scyliorhinus canicula (L.): a study of egg laying rate and nidamental gland secretory activity (1983)

    Notes: Egg-case size, shape and pigmentation are distinctive features of each female lesser-spotted dogfish, Scyliorhinus canicula. During 9 months captivity under constant conditions (water, temperature, photoperiod, food), a laying sequence reminiscent of an annual cycle was observed in three females. While oocyte size and (with exceptions) egg-case weight remained constant, there was a marked decrease of the‘albumen’jelly secreted by the anterior halves of nidamental glands.

    Reproduction and development of two angel sharks, Squatina squatina and S. oculata (Pisces: Squatinidae), off Tunisian coasts: semi-delayed vitellogenesis, lack of egg capsules, and lecithotrophy (1990)
    Oxford, UK : Blackwell Publishing Ltd

    Topics: Biology
    Notes: Distribution, sexual maturity, fecundity, genital asymmetry, cyclic vitellogenesis and gestation are described in the angel sharks Squatina squatina (L., 1758) and S. oculata Bonaparte, I840 from Tunisian waters. With embryonic nutrition being purely lecithotrophic, lack of egg capsules, block of oocyte growth at the beginning of gestation, and inability to ovulate soon after parturition, Squatinidae can be compared to Torpedinidae and to Centroscymnus (Squalidae), except that their vitellogenesis starts again at mid-gestation. This new, special feature has been termed ‘semi-delayed vitellogenesis’ with regard to the delayed vitellogenesis of Torpedinidae andCentroscymnus.

    Surgical endoscopy fellowships (1994)
    Springer
    Surgical endoscopy and other interventional techniques 8 (1994), S. 86-89

    Notes: Abstract This study was conducted to evaluate the career impact of a formalized surgical endoscopy fellowship. Sixteen surgeons who have completed this training were surveyed via questionnaire. Twelve individuals were found to be in teaching settings, 10 had academic appointments, and 12 had published in the endoscopic and gastrointestinal literature. Gastrointestinal endoscopy constituted a mean of 28% of these surgeons' practices. Gastrointestinal surgery was the focus of a mean of 51% of their operative experience, and laparoscopic surgery constituted a mean of 40% of their surgical activity. Twelve of these individuals performed ERCP as part of their clinical practice, and 11 performed advanced laparoscopic surgical procedures. Relationships with nonsurgical endoscopic colleagues were considered positive for 5 surgeons, negative for 7, and neutral for 4. Professional relationships with nongastroenterologic physicians were uniformly positive or neutral. We conclude that formal surgical endoscopy fellowships facilitate subsequent academic and educational activity, foster surgical practices oriented toward gastrointestinal disease, and impact relationships with nonsurgical colleagues in a variable fashion.

    Delayed gallstone abscess following laparoscopic cholecystectomy (1994)
    Springer
    Surgical endoscopy and other interventional techniques 8 (1994), S. 1332-1334

    Notes: Abstract Delayed infectious complications following elective laparoscopic cholecystectomy have not been well delineated in the medical literature. Irretrievable spillage of gallbladder contents at the time of laparoscopic cholecystectomy is not rare, and has generally been felt to be of little consequence, particularly in the nonacute setting. The case presented documents an instance of delayed gallstone abscess formation after elective laparoscopic cholecystectomy. While rare, such cases highlight the need for refined techniques to prevent gallbladder perforation during this procedure and to allow laparoscopic recovery of small gallstones spilled at the time of cholecystectomy.

    Cost-effectiveness of laparoscopic cholecystectomy (1995)
    Springer
    Surgical endoscopy and other interventional techniques 9 (1995), S. 158-163

    Notes: Abstract This study retrospectively evaluated the cost-effectiveness of laparoscopic cholecystectomy compared to open cholecystectomy in a single university-affiliated community hospital. The medical records of all patients that underwent laparoscopic cholecystectomy during 1990 and open cholecystectomy during 1989 in one hospital were reviewed. Hospital stay, hospital charges, surgeons' and anesthesiologists' fees were determined. Fifty patients from each group were contacted to determine recovery time to full activity after surgery. Those having common duct exploration and those converted to open cholecystectomy after an attempted laparoscopic cholecystectomy (n=8) were excluded. A summary of results is included below (Table 1). In our early experience with laparoscopic cholecystectomy we found that the total charges for laparoscopic cholecystectomy were more than for open cholecystectomy when one recognizes the 1-year difference in patient accrual between the two groups. Time to full recovery was markedly reduced in patients undergoing laparoscopic cholecystectomy compared to those having an open procedure. Despite the overall increased total charge with laparoscopic cholecystectomy, the shorter recovery period allowing the patients an earlier return to full preoperative activities contributes to its cost-effectiveness when compared to open cholecystectomy. Further experience with laparoscopic cholecystectomy and refinements in management of these patients should allow for further reductions in charges for this procedure.
