ABSTRACT: Evidence suggests that follow-up after colorectal cancer improves survival. Colorectal cancer is so common that patient follow-up can overwhelm a service, affecting the ability to see new referrals and reassess patients seen previously who have new symptoms. In order to cope with this demand a nurse-led follow-up service was started in 2004. We aimed to review the results of a nurse-led colorectal cancer follow-up clinic.
Between 1 December 2004 and 31 January 2011, patients who underwent resection for colorectal cancer were followed up by a nurse specialist according to a protocol determined by the colorectal surgeons in the unit. All patient details were recorded prospectively in a purpose designed database.
Nine hundred and fifty patients were followed up over 7 years. Some 368 patients were discharged from the follow-up programme, 474 patients remain actively involved in the programme and 108 patients died. Of the patients discharged from the follow-up scheme 269 (73%) were discharged to their general practitioner free of disease after 5 years. Of the 108 who patients died, 98 were as a result of colorectal cancer. Twenty patients (2.1%) were identified with local (peri-anastomotic) disease recurrence and 93 patients (9.8%) were found to have developed distant metastatic disease. Of these, 65 patients (6.8%) were referred for palliative care and 28 (2.9%) had surgery for focal metastatic disease of whom 18 were still alive at the time of this analysis.
This paper shows that a nurse-led clinic for colorectal cancer follow-up can achieve satisfactory results with detection rates of recurrent or metastatic disease comparable to consultant follow-up. A nurse-led clinic provides the benefits of follow-up without overwhelming the consultant colorectal surgical clinic practice.

ABSTRACT: Surgery remains the only option for potential cure in patients with recurrent colorectal cancer. Accurate staging modalities aid in the avoidance of futile surgery, which may result in considerable morbidity in patients with incurable disease. Current imaging techniques used in disease staging often are not sensitive enough to identify low-volume metastatic disease. This study reviews the role of positron emission tomography in the assessment of patients with suspected recurrent colorectal cancer.
A literature search using the PubMed, MEDLINE, and Embase database was performed, locating English language articles on positron emission tomography, positron emission tomography, recurrent colon, and/or rectal cancer. The references of these papers were searched manually for further references.
Positron emission tomography is more sensitive and more specific than conventional diagnostic imaging for metastatic disease and local recurrence respectively. Studies confirm the superior ability of positron emission tomography scans compared with conventional diagnostic imaging in differentiating between scar tissue and invasive tumor. Positron emission tomography scanning is more sensitive and specific for the assessment of liver metastases (and probably in patients with lung metastasis) than conventional diagnostic imaging. Positron emission tomography is superior to conventional diagnostic imaging in the investigation of raised carcinoembryonic antigen in the postoperative patient and alters management in approximately 37 percent of patients with recurrent colorectal cancer. The limitations and cost effectiveness of positron emission tomography are discussed.
Positron emission tomography scanning is emerging as the imaging modality of choice for patients being considered for surgery for locally recurrent colorectal cancer. Positron emission tomography has the greatest impact by detecting unresectable disease and thereby averting inappropriate surgery. Despite the high set-up costs, its use seems to be cost effective.

ABSTRACT: To see whether laparoscopy improves the accuracy of a clinical diagnosis of acute appendicitis in women of reproductive age, and to determine what the long-term sequelae are of not removing an appendix deemed at laparoscopy to be normal.
The initial part of the study was undertaken during 1991-1992. Female patients between 16 and 45 years were eligible for inclusion once a clinical decision had been made to perform an appendicectomy for suspected acute appendicitis. Following consent, patients were randomized into two groups. One group had open appendicectomy, as planned. The other group had laparoscopy, followed by open appendicectomy only if the appendix was seen to be inflamed or was not visualized. The end points for the study were the clinical outcomes of all patients, and the results of histology, where appropriate. An attempt was made to contact all patients at 10 years to determine whether they had had a subsequent appendicectomy, or had been diagnosed with another abdominal condition that might be relevant to the initial presentation in 1991-1992.
Laparoscopic assessment was correct in all cases in which the appendix was visualized. Diagnostic accuracy was improved from 75% to 97%. Laparoscopy was associated with no added complications, no increase in hospital stay in patients who went on to appendicectomy, and a reduction in hospital stay for those who underwent laparoscopy alone. No patients developed a problem over the 10-year follow-up period from having a normal-looking appendix not removed at laparoscopy.
Laparoscopic assessment of the appendix is reliable, and to leave a normal-looking appendix at laparoscopy does not appear to cause any long-term problems.

ABSTRACT: Parastomal hernia following formation of an ileostomy or colostomy is common. This article reviews the incidence of hernia, the technical factors related to the construction of the stoma that may influence the incidence, and the success of the different methods of repair.
A literature search using the Medline database was performed to locate English language articles on parastomal hernia. Further articles were obtained from the references cited in the literature initially reviewed.
Parastomal hernia affects 1.8-28.3 per cent of end ileostomies, and 0-6.2 per cent of loop ileostomies. Following colostomy formation, the rates are 4.0-48.1 and 0-30.8 per cent respectively. Site of stoma formation (through or lateral to rectus abdominis), trephine size, fascial fixation and closure of lateral space are not proven to affect the incidence of hernia. The role of extraperitoneal stoma construction is uncertain. Mesh repair gives a lower rate of recurrence (0-33.3 per cent) than direct tissue repair (46-100 per cent) or stoma relocation (0-76.2 per cent).
The incidence of parastomal hernia is between 0 and 48.1 per cent, depending on the type of stoma and length of follow-up. No technical factors related to the construction of the stoma have been shown to prevent herniation. If repair is required, a prosthetic mesh technique should be considered. Further randomized clinical trials (particularly of extraperitoneal stoma construction) are needed.

ABSTRACT: Radiotherapy has become one of the most important treatment modalities for human malignancy. Tumors affecting the organs of the pelvis are increasingly being irradiated for local treatment benefit, with the subsequent complication of anorectal injury of varying extent. The aim of this review is to determine how to manage the consequences of long-term effects of radiotherapy on the rectum and anus.
A comprehensive search of the literature with manual cross-referencing was performed using the MEDLINE, PubMed, and Cochrane Databases.
Long-term manifestations of injury caused by pelvic radiotherapy include abscess and fistula formation, stricture, mucus discharge, urgency, tenesmus, diarrhea, increased risk of cancer, and most commonly, bleeding. Most patients present with several symptoms; however, usually one symptom dominates.
Many of these symptoms are self-limiting, and mucosal complications may often be treated by nonsurgical methods such as topical formalin application, endoscopic argon plasma coagulation, and hyperbaric oxygen therapy. Conservative measures have not been shown to be of benefit if symptoms persist. Structural abnormalities and septic complications are likely to require surgery. Modern techniques in the delivery of radiotherapy help minimize the likelihood of rectal complications.
