[Use of mechanical staplers for the solution of proctological problems. Our experience with 122 patients]. / Uso della suturatrice meccanica nella risoluzione di problematiche proctologiche. Nostra esperienza relativa a 122 pazienti.

The Longo technique using a circular stapler has changed haemorrhoid therapy. Thanks to the advent of this technique for treating haemorrhoids without excision, we can now successfully eliminate the mechanism responsible for their pathogenesis. The aims of circumferential stapled anoplasty are to correct the anodermal prolapse and restore the haemorrhoidal cushions to their anatomical position. Furthermore, with a few variants the technique can be utilised for other proctological problems, such as obstructed defecation in rectocele and incomplete internal prolapse (or rectal intussusception). The authors report on their experience in a consecutive series of 122 cases undergoing circular stapled anoplasty for haemorrhoids, associated in 10 cases with rectocele or rectal intussuscep-tion, analysing early and late complications after an accurate follow-up. The procedure can be performed with local or spinal anaesthesia. The operation lasted on average 19 minutes. There were few complications: early bleeding (4.9%), late bleeding (0.8%), mild stricture (2.5%) and thrombosis of external piles (8.2%). This new surgical technique is effective and rapid, causes only minimal postoperative pain and could be proposed as an alternative to traditional surgery also in the day surgery setting.

[Carcinoid tumor of the appendix. A not especially rare entity]. / Il tumore carcinoide dell'appendice. Un'entità non proprio rara.

Carcinoid tumors arise from neuroendocrine system and one of their preferred sites is the appendix. Most of appendiceal carcinoids almost always are clinically silent and are incidentally found at histological examination. For this reason, histological examination of the appendix is recommended in every case of the appendicectomy. Prognostic factors are: tumor stage, histologic pattern and differentiation. The authors present 6 cases of appendiceal carcinoid tumor, clinically silent and found at histologic examination (3 cases of appendicectomy for acute appendicitis, 3 cases of appendicectomy associated with abdominal surgical interventions for other pathology) and compare their experience with the most recent literature on this subject. The conclusion is drawn that the size of this tumor is the main factor that surgeons must consider for the choice of surgical treatment. Incidental, clinical silent, small (less than 2 cm in size) appendiceal carcinoid tumors can be treated by appendicectomy, and they do not need follow-up. Greater (more than 2 cm in size) appendiceal carcinoid tumors, in young patients must be treated with a right hemicolectomy and they need follow-up (periodically radiological, ultrasonographic and endoscopic examinations, tumor markers) because there is the possibility of recurrence or metastases.
