Self-expanding metal stent placement for oesophageal cancer without fluoroscopy is safe and effective

Background. Self-expanding metal stents (SEMS) are widely used to palliate patients with oesophageal cancer. Placement is usually done under endoscopic and fluoroscopic guidance. We have developed an exclusively endoscopic technique to deploy these stents. This article documents the technique and periprocedural experience.Patients and methods. All patients who had SEMS placement for oesophageal cancer at Grey’s Hospital, Pietermaritzburg, South Africa, over a 5-year period (2007 - 2011) were reviewed. Stenting was performed without radiological guidance using the technique documented in this article. At endoscopy, the oesophageal lesion was identified, dilated over a guidewire if necessary, and a partially covered stent was passed over the wire and positioned and deployed under direct vision. Data were captured from completed procedure forms and included demographics, tumour length, the presence of fistulas, stent size and immediate complications.Results. A total of 480 SEMS were inserted, involving 453 patients, of whom 43 required repeat stenting. There were 185 female patients (40.8%) and 268 male patients (59.2%). The mean age was 60 years (range 38 - 101). There were 432 black patients (95.4%), 15 white patients (3.3%) and 6 Indian patients (1.3%). The reasons for palliative stenting were distributed as follows: age >70 years n=95 patients, tumour >8 cm n=142, tracheo-oesophageal fistula (TOF) n=29, and unspecified n=170. One patient refused surgery, and one stent was placed for a post-oesophagectomy leak. Repeat stenting was for stent migration (n=15), tumour overgrowth (n=26) and a blocked stent and a stricture (n=1 each). Complications were recorded in six cases (1.3%): iatrogenic TOF (n=2), false tracts (n=3) and perforation (n=1). All six were nevertheless successfully stented. There was no periprocedural mortality.Conclusion. The endoscopic placement technique described is a viable and safe option with a low periprocedural complication rate. It is of particular use in situations of restricted access to fluoroscopic guidance

Oesophageal cancer in South Africa: The long timeline from onset of symptoms to definitive management

Background: In rural South Africa, most patients with oesophageal cancer have delayed presentations with debilitating symptoms and inoperable disease. This study was undertaken to quantify the delay between onset of symptoms and definitive treatment in a cohort of patients in rural South Africa, presenting to a state hospital in KwaZulu-Natal. The study also sought to establish reasons for delays in seeking medical attention and identify ways to encourage earlier presentation. Methods: It was a two-armed study of patients with oesophageal cancer seen at Greys Hospital in Pietermaritzburg. One was a retrospective chart review establishing a timeline. The second part was a prospective study between June and November 2012 where data were collected by means of patient interviews. Results: One hundred and thirteen charts were reviewed. The time from first symptoms to definitive management ranged from 2 to 14 months (average 7 months). Forty-six patients were interviewed. All experienced dysphagia but 83% were only prompted to seek help after weight loss. The duration of symptoms prior to first clinic or hospital attendance was 0–12 months (average 3 months). The reasons for the delay included the following: 41% of patients did not consider dysphagia a significant symptom, 24% had no money, 19% sought the help of traditional healers first and 15% said the hospital was too far away. Conclusion: There are long delays in the management of oesophageal cancer in our setting. The delays are prehospital as well as within the health care system. Lack of knowledge about oesophageal cancer symptoms and limited access to health care contributed to delays in management. Targeted quality improvement interventions are necessary. Patient education and improved referral systems are vital in encouraging earlier presentation

Oesophageal cancer in Area 2 of Kwazulu-Natal: predictors of late presentation.

BACKGROUND: There are limited prospective data sets on clinical characteristics, stage of presentation and treatment of patients with Oesophageal Squamous Cell Carcinoma (OSCC) in South Africa. This study aimed to assess the frequency and severity of clinical characteristics associated with late presentation of patients with OSCC presenting to a cancer referral centre in KwaZulu-Natal, South Africa. METHODS: A prospective consecutive series of patients presenting with confirmed OSCC treated at Greys Hospital in 2016/2017 were enrolled. Data collected included: age, gender, home language, referral centre, clinical and laboratory characteristics: dysphagia score, Eastern Cooperative Oncology Group (ECOG) performance status, body mass index (BMI), serum albumin, tumour pathology and treatment administered. RESULTS: One hundred patients were analysed. Ninety four percent spoke isiZulu. The mean age was 61 with a male to female ratio of 1.5:1 Ninety percent had palliative treatment as their overall assessment precluded curative treatment. Five patients underwent curative treatment. The age standardised incidence (ASR) was 25.2 per 100 000. The factors associated with late presentation and their frequency were: advanced dysphagia grade ( </=2 in 68%), malnutrition (BMI <18.5kg/m2 in 49%), hypoalbuminaemia (serum albumin < 35 g/l in 70%), poor performance status (ECOG</=2 in 50% ) and moderate to poor tumour differentiation in 95% of patients. CONCLUSION: OSCC in Kwazulu-Natal has double the ASR of South Africa and places a significant burden on the region's health care system. Factors associated with late presentation occur in the majority and alone or in combination preclude curative therapies. The frequency of these factors serve as a benchmark for comparison, and reduction in their frequency may indicate effectiveness of interventions designed to improve awareness and access to proper care

Developing a novel laparoscopic training model during the Covid-19 pandemic in a resource-limited setting

Background: This paper describes the development and implementation of a unique laparoscopic suturing course in a resource-constrained setting and reviews the initial experience with the program. Methods: This study describes the development of Grey's laparoscopic suturing course (GLSC) and reviews the questionnaires and feedback over the past year. Results: The GLSC has been run for over a year and has enrolled 47 participants. Most participants were registrars, followed by consultants and medical officers, and most participants had limited minimal access surgery (MAS) experience. Only three had previously undertaken a formal course or observership. The mean result for the pre-course test was 50%, and for the post-course test, 88%. During the skills laboratory session, every participant competently performed intra-corporeal suturing. The entire group unanimously agreed that the GLSC should be recommended for all surgical trainees in the evaluation form. All participants expressed interest in an advanced MAS course. Conclusion: We have demonstrated that developing a local MAS suturing course with limited resources and industry support during the Covid 19 pandemic is possible. It has benefited a large group of trainees thus far and hopefully will become part of the curriculum of surgical trainees in South Africa
