Burns to the genitalia and the perineum.

PURPOSE: We conducted a study to determine the treatment of perineal and genital burns, the results of therapy and the complications of such burns. MATERIALS AND METHODS: A review of the records of 4,216 patients treated between 1981 and 1995 at the Burn Center of the Academic Surgical Center Stuivenberg, revealed 87 male and 30 female patients, 6 months to 86 years old who had associated burns to the perineum or genitalia. Mean burn size was 21% of the total body surface area. Causes of burn injury were scald in 55% of the cases, flame in 24%, chemical in 16% and others in 4%. RESULTS: There were 16 deaths in this group (13.6%) but none was related to the perineal or genital burns. Of the 101 survivors 41% required Foley catheters but the catheters were indwelling during resuscitation only (range 1 to 99 days). Perineal and genital burns were treated by topical antimicrobials. Only 10 patients (9.9%) required split-thickness skin grafts. As late complication 2 patients had scar formation of the penile shaft, which was treated with multiple Z-plasties, and of the prepuce, which was treated by circumcision, respectively. In 1 patient, who presented with erectile dysfunction diagnostic evaluation was negative. CONCLUSIONS: Conservative management of perineal and genital burns is recommended.

Laparoscopic transperitoneal versus extraperitoneal inguinal hernia repair: a prospective clinical trial.

A prospective series of 106 inguinal hernias in 91 patients is studied, comparing two methods of laparoscopic hernia repair: a transperitoneal technique with preperitoneal stapled mesh fixation (TransAbdominal PrePeritoneal or TAPP-technique) performed in 33 patients, and a totally extraperitoneal placement of non stapled mesh (Totally ExtraPeritoneal Approach or TEPA-technique) performed in 58 patients. Conversions to open repair were equally frequent (5% vs. 7% respectively) and were due to adhesions, haemorrhage, irreducible intestinal loop in the hernial sac or important subcutaneous emphysema. Minor postoperative complications included regional seroma or haematoma, testicular pain and meralgia paraesthetica. There was no mortality nor long lasting complication. Recurrence rates in both groups amounted 2.7% (TAPP) and 2.8% (TEPA) respectively after a mean follow-up of 15.8 months (TAPP) and 17.6 months (TEPA). In both groups early recovery of normal activities was noted, after a mean of respectively 13.6 days (TAPP) and 12.9 days (TEPA). It is concluded that the transabdominal route and the totally extraperitoneal approach for laparoscopic herniorrhaphy are both adequate techniques for inguinal hernia repair with similar complication and short-term recurrence rates.

Laparoscopic repair of perforated duodenal ulcer. A prospective multicenter clinical trial.

BACKGROUND: A series of 100 consecutive patients with perforated peptic ulcer were prospectively evaluated in a multicenter study. The feasibility of the laparoscopic repair was evaluated. METHODS: All patients had peritonitis, 20% were in septic shock, and 57% had delayed perforation. Conversion to laparotomy was necessary in eight patients. The morbidity rate was 9% and mortality rate 5%. RESULTS: The mean delay of postoperative gastric aspiration (mean 3.4 days) and resumed food intake (mean 4.4 days) as well as the mean postoperative hospital stay (mean 9.3 days) were comparable to conventional surgery, but postoperative comfort was subjectively increased by laparoscopy and noticed by all laparoscopic surgeons participating in this study. CONCLUSIONS: Laparoscopic repair of perforated peptic ulcer proves to be technically feasable and carries an acceptable morbidity and mortality rate, compared with conventional surgery.

Comparison of radionuclide labelled test meals versus endoscopy in the preoperative assessment of the gastric outlet patency.

A series of 39 patients with peptic ulcer disease is investigated with respect to gastric outlet obstruction. Two diagnostic tools are compared, namely endoscopy and evaluation of radionuclide meal emptying. Endoscopic obstruction was qualified as non passage of a 14 mm gastroscope. Gastric emptying reduction was considered clinically relevant when half emptying times exceeded 60 minutes for solids and 12 minutes for liquids. Comparison of both techniques of radionuclide meal emptying with endoscopy showed a poor correlation (accuracy 15/28), especially when liquid gastric emptying versus endoscopy was concerned.

Burns to the genitals and the perineum in children.

OBJECTIVE: To determine the management of perineal and genital burns in children. PATIENTS AND METHODS: Twenty-seven children (aged 6 months to 12 years) suffering from genital or perineal burns between 1981 and 1995 were reviewed. Most burns occurred in boys (70%), were due to scalds (85%) and caused superficial second-degree lesions (63%). The initial treatment consisted of topical antimicrobials or grafting with allografts. RESULTS: Spontaneous healing by conservative therapy, not early excision therapy, occurred in 96% of the patients. Contractures occurred in two patients and were treated with multiple Z-plasties and circumcision. CONCLUSION: The management of perineal and genital burns in children should be conservative.

Pancreatic secretion after anterior gastric wall stapling with posterior truncal vagotomy in dogs.

Anterior gastric stapling with posterior truncal vagotomy has previously been investigated for its effect on canine gastric acid reduction and motility. Posterior truncal vagotomy could, however, induce reduced pancreatic function, which has been observed after total abdominal vagotomy. In this study, pancreatic secretion has been investigated after anterior gastric stapling with posterior truncal vagotomy in a series of canine experiments by means of a stimulation test. On the long term, no significant postoperative reduction of exocrine pancreatic secretion was observed.

An interactive visual man-patient interface for semimmersive endoscopic surgery.

Endoscopy, a we know it today, is far from perfect. In an attempt to make the interventions as little invasive as possible, the ergonomics of the procedure, for the surgeon, are often not dealt with at all. In an attempt to improve the surgeon-patient interface during endoscopic procedures, a new concept is presented to allow the surgeon a much more natural visual interaction with the inside of the patient. It is made possible for the surgeon to look around into the cavity, with a stereo endoscope, mounted on a robot arm. This robot arm is directed by the motion of the head of the surgeon.

[Andreas Vesalius, distinguished surgeon of the 16th century].

The author gives here some considerations about A. Vesalius through his life and his works as a surgeon. He was the father of the anatomical revolution against Galen but was also an eminent clinician and surgeon. He was immediately able to adapt his surgical practice whenever the promising methodology was identified (see Consilia). The author concludes with a critical analysis of the Chirurgia magna in septem libros digesta attributed to A. Vesalius.

[Changes in eating habits and disease symptoms in the 16th and 17th centuries].

The Renaissance period in Europe saw many dietary changes due to imports of new ingredients from the Far East as well as from newly discovered Central and South America. Maize and potatoes rapidly conquered European markets and because of their easier cultivation and higher calorie content, displaced grains such as wheat and rye. Drinking habits too changed, when tea, coffee and chocolate were introduced, first as strengthening medicines, later as 'delicatessen' in the aristocratic British and French cafés. These new foods and beverages may have helped diminish the periods of famine typical of Medieval and Early Renaissance times. In the 16th and 17th century, new diseases were described that were directly related to dietary intake. Ergotism and scurvy, particularly, sometimes decimated whole populations in rural areas or at sea. It was not until the 18th century that scientific research elucidated the cause of such diseases and helped us to understand the importance of a balanced diet.

Anterior gastric wall stapling combined with posterior truncal vagotomy in the treatment of duodenal ulcer.

Anterior gastric stapling with posterior truncal vagotomy was examined as an alternative to highly selective vagotomy in the treatment of peptic ulcer disease. A clinical series of 32 patients who underwent the combined procedure is presented; gastric acid output was adequately reduced (basal output by 82 per cent, peak by 64 per cent). Motility changes were temporary and mild. Clinical follow-up, using a modified Visick grading, showed good to excellent results in 21 of 25 patients who could be classified. This procedure is suggested as an appropriate alternative to highly selective vagotomy.

Management of digestive fistulas.

BACKGROUND: The efficacy of total parenteral nutrition and somatostatin was assessed in reducing output and promoting spontaneous closure of postoperative digestive fistulas. METHODS: In a consecutive series of 23 patients, closure was achieved in 83% of patients after a mean fistula duration of 11.0 +/- 7.9 days and a mean of 13.2 +/- 7.0 days of drug treatment, and without mortality. RESULTS: A marked first-day effect (output drop > 50%) was noted in 60% of patients and had a good prognosis. Infection of the fistula markedly prolonged fistula closure time, but did not affect total outcome. CONCLUSION: Somatostatin has been shown to be very useful in the conservative treatment of digestive fistulas because of its ability to reduce output significantly and to accelerate spontaneous closure.

[Andreas Vesalius and surgery].

By publishing De Humani Corporis Fabrica Libri Septem in 1543, Andries van Wesel (1514-1564) gave surgical science an immense impulse. The revolutionary renovation in the knowledge of man's anatomical structure changed slowly and progressively into topographical and physiological understanding of surgical diseases. At the same time, this made better aimed and more secure operations possible. Apart from the importance of this anatomical publication, Andreas Vesalius also won his spurs as a surgeon. He taught surgery in Padua for many years. He was appointed court physician and surgeon at the Habsburg Court of Charles V and Philip II. He personally performed lots of operations known at the time as major ones. He not only quickly adopted the surgical innovations of his fellow-surgeon Ambroise Paré, but he even performed operations that had been forgotten during several centuries, among which thoracocentesis for pleural empyema. His clinical perspicacity in discovering the indication for some operations was staggering and was appreciated by all great monarchs of Europe in the 16th century. In his several consilia, numerous pieces of advice were given for the treatment of surgical patients. The surgical practice which Vesalius had in Brussels for many years, consequently became most successful. Many publications by Vesalius about surgery and blood-letting are well-known. His Chirurgia magna in septem Libros digesta still remains controversial; these books were published by Prospero Borgarruccio (1560) in 1568 by the Venetian editor Valgrisi. This book gives an excellent survey of surgical pathology as it was taught and treated in the 16th century. The scientific method that Vesalius used, not only in his anatomical studies but also in his surgical practice, deserves not only our full appraisal but should still be studied in our own time.
