[Pelvi-rectal abscesses. Diagnosis, treatment and follow-up by transrectal ultrasonography].

Pelvirectal abscess usually presents with vague symptoms which may delay diagnosis and subsequent treatment. However, it is important to recognize this condition since these abscesses may interfere with the sphincter function or give rise to chronic fistulo-in-ano. We describe two patients in whom transrectal ultrasound was applied for diagnosis, and who were treated for a pelvirectal abscess. Both patients were admitted to our hospital because of tumour of the rectum. There were few symptoms and signs of infection. Transrectal ultrasound examination of the rectum made a significant contribution to early diagnosis. We also point out the advantage of transrectal ultrasound examination during follow-up, mainly because we were able to rule out malignant neoplasm by obtaining an ultrasound-guided specimen for histological examination.

[Rectal cancer. Staging with transrectal ultrasonography].

30 patients with carcinoma of the rectum were examined preoperatively with endoluminal rectal ultrasound and digital examination in order to assess the stage of the tumour. The results were compared with the histopathological findings in the resected specimens from 23 patients. The following operations were performed: 11 abdominoperineal rectal amputations, five low anterior resections and seven local excisions. Discrepancies between the ultrasonic and histological staging occurred in seven patients, six tumours were overstaged and one understaged ultrasonically. Digital assessment overstaged eight tumours and understaged two. The ultrasonic examination provided additional information in 12 patients.

[Intraoperative ultrasonography of the liver].

Intraoperative ultrasound is the most recent diagnostic tool in liver surgery. It presents the surgeon with a technique that can provide detailed information about liver tumours and their topography prior to surgery. It also provides very good visualization of the vascular tree of the liver. This article gives a detailed description of the technique of intraoperative ultrasound of the liver. It also presents results from two groups of patients: 30 patients who underwent laparatomy for colorectal cancer (n = 16) or for liver tumours (n = 14) were examined by intraoperative ultrasound of the liver. The results were compared with the observations made by preoperative ultrasound examination. In seven patients the intraoperative ultrasound examination showed liver tumors that had not been detected preoperatively. The intraoperative ultrasound was decisive for the operative strategy in three of the patients treated for liver tumours. In one of the patients operated on for colorectal cancer, in whom the intraoperative ultrasound examination revealed a previously unrecognized metastasis, a liver resection is now planned. Our study confirms that intraoperative ultrasound is a valuable form of examination in patients treated for colorectal cancer and is important for deciding the surgical strategy for patients treated for liver tumours.

[Surgical treatment of gastroesophageal reflux. Evaluated by manometry and 24-hour pH monitoring of the esophagus].

From 1980 to 1989, 46 patients underwent surgery for pathological gastro-oesophageal reflux disease; 28 with Nissen technique, nine with Hill technique and nine with a modified Belsey technique. 11 patients (24%) experienced postoperative complications, 21% after Nissen, 33% after Hill and 22% after Belsey. Two of six patients suffered recurrence of their reflux symptoms after Belsey, three of six after Hill and two of 26 (8%) after Nissen. 85% experienced no reflux symptoms after Nissen fundoplication. 17 patients suffered from flatulence, three were not able to belch and two were not able to vomit. Median lower oesophageal sphincter pressure before Nissen fundoplication was 6.0 mmHg and length was 2.0 cm. After the operation the pressure increased to 10.0 mmHg and the length to 3.0 cm. Four patients underwent ambulatory 24-h oesophageal pH monitoring both preoperatively and postoperatively. The preoperative registration was pathological in all patients, but in three patients the postoperative pH was normal.

[Severe hemorrhage in pancreatic pseudocyst].

Pseudocysts in the pancreas occur in 10% of patients with pancreatitis and may lead to serious complications, i.e. infection, obstruction of the bile duct, rupture, and hemorrhage. The last complication is highly lethal. Two patients are described, with differing modes of presentation and therapy. In one patient hemostasis was obtained by surgical packing followed by percutaneous embolization. In the other patient embolization failed and surgical resection was necessary.

[Distal esophageal banding. A modified method of surgical treatment of obesity].

64 patients were treated with distal oesophageal banding for morbid obesity from 30/4-1984 to 1/6-1988. By this method a Dacron vascular prosthesis is passed around the oesophagus from incisura cardiaca to pars cardiaca. There will be no upper ventricular pouch. The method was introduced in order to avoid the problems seen after operation with gastric banding, such as valve mechanism secondary to pouch distension and band penetration. Such problems have not been encountered following our operative modification. 18 patients were observed for more than two years. The mean weight loss one year after operation was 28 kg, which was equivalent to 26% of preoperative weight. The main problem is excessive tightening of the band. Therefore, in three patients, the band had to be removed later.
