We studied the sonographic findings in seven patients in whom afferent loop obstruction was first detected by sonography. All seven subsequently were proved at surgery to have afferent loop syndrome. The causes of the obstruction included internal hernia (n = 3), cancer recurrence (n = 2), marginal ulcer (n = 1), and development of cancer at the anastomosis site (n = 1). In all cases, the dilated afferent loop was seen on sonography as a tubular structure in the upper abdomen crossing transversely over the midline. The distal end of the afferent loop could be traced toward the anastomosis. The probable cause of the syndrome was predicted on the basis of sonography in two of three patients with cancer at the anastomosis. Our experience suggests that afferent loop syndrome can be diagnosed sonographically on the basis of the detection, location, and shape of the dilated afferent loop.

Perineal hernia (PH) is formed by the protrusion of intra-abdominal viscera through a defect in the pelvic floor. This is a rare complication after conventional abdominoperineal resection, pelvic exanteration, proctectomy, and other pelvic procedures. The purpose of the present paper is to report 4 cases of PH after laparoscopic abdominoperineal resection for rectal cancer and to review literature data about the incidence, predisposing factors, and treatment of this challenging problem. When added to other 3 cases previously reported in the Brazilian series of laparoscopic surgery, this group of 7 cases comprises a PH incidence of 3.5% after rectal resection procedures. Surgical treatment is indicated only in symptomatic patients with no signs of cancer recurrence. Proposed methods of surgical repair include abdominal, perineal, or combined approaches to the hernia in association with the use of autologous tissues or prosthetic meshes. Preventive measures are represented by closure of the pelvic peritoneum whenever possible, primary perineal suture and wound care to avoid infection.

The Authors, regarding their emergency surgical experience, examine the need of reintervention in abdominal surgery at a distance (operations carried out not less than 30 days after previous procedure), a controversial situation, usually dealt with empirical approach. Such a feature is not rare in the experience of a surgeon; nevertheless still few are the studies concerning the severity of the disease and related complications requiring surgery. Occasionally it is really difficult--quite impossible- in these often complex clinical conditions, to identify the aetiology and even to perform a pre-operative diagnosis. Sometimes other factors may inhibit an exhaustive evaluation (acute onset of the symptoms, time spent from the former procedure, choice of the patient to refer to another surgeon) thus conditioning an adequate review of the first surgical act. The Authors study the more frequently observed clinical features, post-surgical abdominal adhesive syndrome, cancer recurrence, incisional hernia. Former surgical diseases and the latter one may be the same, but not necessarily. Surgery is only a feature of the treatment (multimodal treatment) in case of neoplastic recurrence. Morbidity and mortality concerning the latter surgical procedure are higher than the mere sum of those related to both the former and last operation performed (pre-operative disease understaging). Finally it must be stressed the need for early and accurate diagnosis to clearly steer the choice and course of surgical action.
