[Pancreatoduodenal resection for carcinoid of Vater's papilla].

Papilla Vateri carcinoid is among the very rarely occurring locations of the lesion. The small lumen of the papilla is the underlying cause of becoming clinically manifest with icterus rather early. Accessibility of the process for endoscopic biopsy facilitates the diagnosis. Even histologically it is very difficult to differentiate benign from malignantly altered carcinoids. Only the existence of metastases confirm with certainty their malignant nature. An observation on papilla Vateri carcinoid in a 60-year-old woman, proved preoperatively through cytological study, is reported. Intraoperative--no metastases are discovered. Sparing pancreatoduodenal resection is performed with a good functional outcome, recorded at the checkup examination after two years.

[A pathogenetic approach to the surgical treatment of large postoperative hernias].

Intractable intraoperative retraction of the abdominal musculature, associated with large postoperative hernias, give rise to reduced abdominal cavity volume, increase of intra-abdominal pressure and pulling along the suture line. These are factors considered as preconditions of the development of postoperative complications and recurrences. Experience with intraoperative facilitation by the application of relief incisions on the aponeurosis of the external oblique abdominal muscles according to Borodin et al during restoration of the abdominal wall continuity at the site of defect is shared. The procedure described is used in the operative management of ten patients presenting large postoperative hernias following superior median laparotomy, in two of them recurrent, one female patient following Rio Branco's operative access, and two cases with recurrent hernia after appendectomy. A complication--operative wound hematoma--is recorded in a single female patient only. The uneventful postoperative course, and the absence of recurrences over periods ranging from several months to two years, are good reasons to discuss the experience so far accumulated, and recommend the method for the practice.

[An anatomicophysiological validation of hernioplasty in inguinal hernias].

Contemporary understanding of the pathogenesis of inguinal hernias modifies the approach to solution of the problem from elementary anatomical to anatomical and functional. This in turn implies a number of specific demands on their treatment, such as: 1) preserving the oblique course of the canal in the abdominal wall, 2) endeavours to utilize the functionally synergetic elements of the respective layer for plastic repair of the defect, and 3) attempt at noninterference with the pump-valve function of the canal during plastic modelling of either of the openings. In both types of inguinal hernia, posterior plasties are pathogenetically justified. Positive experience had with 37 patients, operated for inguinal hernia after the methods of Shouldice, McVay and Kukudzhanov, or by combining single elements of the latter, is shared. The series analyzed comprises 18 cases presenting indirect hernia, 8-direct, 8-simultaneously direct and indirect, and 3-recurrent hernia. The extrafascial access to Cooper's ligament described contributes to the beneficial outcome.

[Peritoneal carcinosis diagnosed during herniotomy].

A case of inguinal hernia is described where metastasis from adenocarcinoma with mucinous products in the bottom of the sac are discovered intraoperatively. Prior to operation, the patient is suspected for abdominal organ carcinoma, but no evidence of such a lesion is documented. Persistent complaints of painfulness in the region of hernia is the cause prompting the undertaking of herniotomy. Whenever the hernial sac is implicated in pathologic processes involving peritoneum and abdominal organs, the clinical manifestations of the intraabdominal process and of the hernia proper are modified.
