Survival pattern of colorectal cancer in Sub-Saharan Africa: A systematic review and meta-analysis. Cancer Epidemiol 2022; 81:102276. [PMID: 36257176 DOI: 10.1016/j.canep.2022.102276] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 10/01/2022] [Accepted: 10/04/2022] [Indexed: 12/03/2022]
Abstract
Cancer incidence is relatively low in sub-Saharan Africa (SSA), however, prognosis is expected to be poor in comparison with high-income countries. Comprehensive evidence is limited on the survival pattern of colorectal cancer patients in the region. We conducted a systematic review and meta-analysis to investigate the pattern of colorectal cancer survival in the region and to identify variation across countries and over time. We searched international databases MEDLINE, Scopus, Embase, Web of Science, ProQuest, CINAHL, and Google Scholar to retrieve studies that estimated survival from colorectal cancer in SSA countries from inception to December 31, 2021 without language restriction. Due to between-study heterogeneity, we performed a random-effects meta-analysis to pool survival rates. To identify study-level sources of variation, we performed subgroup analysis and meta-regression. Results are reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020 guideline and the protocol was registered in PROSPERO database (CRD42021246935). 23 studies involving 10,031 patients were included in the review, of which, 20 were included in the meta-analysis. The meta-analysis results showed that the pooled 1-, 2-, 3-, 4-, and 5-year survival rates in SSA were 0.74 (95% CI, 0.66-0.81), 0.50 (95% CI, 0.41-0.58), 0.36 (95% CI, 0.27-0.47), 0.31 (95% CI, 0.22-0.42), and 0.28 (95% CI, 0.19-0.38) respectively. Subgroup analyses indicated that the survival rate varied according to year of study, in which those conducted in recent decades showed relatively better survival. The 5-year survival was higher in middle-income SSA countries (0.31; 95%CI: 0.17-0.49) than low-income countries (0.20; 95%CI: 0.11-0.35), however, the difference was not statistically significant. In conclusion, survival from colorectal cancer is low in sub-Saharan Africa compared to other regions. Thus, intervention strategies to improve screening, early diagnosis and treatment of colorectal cancer should be developed and implemented to improve survival in the region.

J Gastrointest Surg 2016; 20:619-23. [PMID: 26643298 DOI: 10.1007/s11605-015-3039-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2015] [Accepted: 11/23/2015] [Indexed: 01/31/2023]
Abstract
BACKGROUND Nowadays, laparoscopic abdominoperineal resection (LAPR) not only has the same oncologic safety of open surgery and but also has the common advantages of laparoscopic surgery. However, given the difficulty in operation and long operative time, laparoscopic extraperitoneal colostomy construction is rarely practiced and reported. In this study, we describe technique of extraperitoneal colostomy using circular stapler following LAPR and demonstrate its efficacy and safety. METHODS This is a retrospective analysis of prospectively maintained data of 42 patients who underwent LAPR with circular stapler-assisted extraperitoneal colostomy in our department between July 2011 and June 2014. RESULTS The mean time for extraperitoneal colostomy construction was 25 min (18-33 min). The mean operative time, estimated blood loss, postoperative gastrointestinal function recovery time, and duration of postoperative hospital stay were 160 min (115-225 min), 45 ml (10-250 ml), 33 h (26-45 h), and 8.6 days (6-13 days), respectively; 4.8 % of the patients had postoperative short-term complications. There were no stenosis, prolapse, and parastomal hernia observed in follow-up period. At 6 months after operation, 26 patients (62 %) claimed to be satisfied with their postoperative stool habits, 29 patients (69 %) had sensation to defecate per stoma, and 11 (26.2 %) patients had the ability to defer defecation for solid or liquid stool per stoma. CONCLUSION Circular stapler-assisted extraperitoneal colostomy is an easy, effective, and safe technique following LAPR and appears to minimize the occurrence of stomal complications and improve the quality of life for patients.

Abstract
PURPOSE Extra-levator abdominal perineal excision of rectum (eLAPE) for low rectal tumours is associated with a lower incidence of circumferential resection involvement. However, there is no consensus on the ideal technique for perineal reconstruction following eLAPE. We thereby conducted a 5-year review of perineal closure outcomes following eLAPE. METHODS A systematic review of the literature was conducted between 2006 and July 2012. Perineal wound healing and complications in the post-operative period were examined. RESULTS Original data following eLAPE were found in 27 studies involving 963 individuals to inform a qualitative synthesis. Pooled analysis revealed that investigators most commonly employed either biomesh closure (12 studies, n = 149), myocutaneous flap closure (9 studies, n = 201) and primary closure (4, n = 578). The incidence of minor and major wound complications and perineal hernias across the latter groups was (27.5, 13.4 and 2.7 %), (29.4, 19.4 and 0 %) and (17.1, 6.4 and 1.2 %), respectively. Two studies utilised synthetic mesh closure (n = 4) and omentoplasty (n = 31). Objective assessment of wound healing was strikingly deficient across most studies, largely due to low level retrospective evidence lacking randomised controls. Modest cohort sizes with short follow-up data were evident due to the relative novelty of eLAPE. CONCLUSION The paucity of high quality data, suggests that a prospective, randomised trial is needed to determine the ideal technique for perineal reconstruction following eLAPE.

Extraperitoneal vs. intraperitoneal route for permanent colostomy: a meta-analysis of 1,071 patients. Int J Colorectal Dis 2012; 27:59-64. [PMID: 21892608 DOI: 10.1007/s00384-011-1293-6] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 08/03/2011] [Indexed: 02/04/2023]
Abstract
BACKGROUND Parastomal hernia is a common complication after colostomy construction. Whether an extraperitoneal route for colostomy creation can reduce the risk of parastomal hernia remains controversial. OBJECTIVE A meta-analysis was performed to evaluate the value of extraperitoneal route in the prevention of parastomal hernia and other postoperative complications related to colostomy. DATA SOURCES A literature search of Medline, Embase, Ovid, and Cochrane databases from the years 1966 to 2010 was performed. STUDY SELECTION Studies comparing extraperitoneal colostomy with intraperitoneal colostomy were identified. INTERVENTION Extraperitoneal colostomy was performed to prevent colostomy-related complications. MAIN OUTCOME MEASURES Data on the following outcomes were sought: incidence of postoperative colostomy complications including parastomal hernia, prolapse, and bowel obstruction. RESULTS Seven retrospective studies with a combined total of 1,071 patients (250 extraperitoneal colostomy and 821 intraperitoneal colostomy) were identified. There was a significantly lower rate of parastomal hernia (odds ratio, 0.41; 95% confidence interval, 0.23-0.73, p = 0.002) in the extraperitoneal colostomy group. However, the occurrences of bowel obstruction and prolapse were not significantly different between the two groups. LIMITATIONS A limitation of the study lies on the meta-analysis of observational studies. CONCLUSION Extraperitoneal colostomy is associated with a lower rate of postoperative parastomal hernia as compared to intraperitoneal colostomy. Prospective randomized controlled trial is warranted to further determine the role of extraperitoneal route in the prevention of parastomal hernia.

Ghost ileostomy after anterior resection for rectal cancer: a preliminary experience. Langenbecks Arch Surg 2011; 396:997-1007. [PMID: 21479620 DOI: 10.1007/s00423-011-0793-8] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2010] [Accepted: 03/21/2011] [Indexed: 12/13/2022]
Abstract
PURPOSE The aim of this study was to describe and evaluate the feasibility and the eventual advantages of ghost ileostomy (GI) versus covering stoma (CS) in terms of complications, hospital stay and quality of life of patients and their caregivers after anterior resection for rectal cancer. METHODS In this prospective study, we included patients who had rectal cancer treated with laparotomic anterior resection and confectioning a stoma (GI or CS), in the period comprised between January 2008 and January 2009. Short-term and long-term surgery-related mortality and morbidity after primary surgery (including that stoma-related and colorectal anastomosis-related) and consequent to the intervention of intestinal recanalization (CS group) and GI closure were evaluated. We evaluated hospital stay and quality of life of patients and their caregivers. RESULTS Stoma-related morbidity rate was higher in the CS group than in GI group (37% vs. 5.5%, respectively, P = 0.04). Morbidity rate after intestinal recanalization in the CS group was 25.9% and 0% after GI closure (P = 0.08). Overall stoma morbidity rate was significantly lower in the GI group with respect to CS group (5.5% vs. 40.7%, respectively, P = 0.03). CS group was characterized by a significantly longer recovery time (P = 0.0002). Caregivers and stoma-related quality of life were better in the GI group than in CS group (P < 0.0001 and P = 0.0005, respectively). CONCLUSIONS GI is feasible, characterized by shorter recovery, lesser degree of total, as well as anastomosis-related morbidity and higher quality of life of patients and the caregivers in respect to CS. We suggest that GI (should be evaluated as an alternative to conventional ileostomy) could be indicated in selected patients that do not present risk factors, but require caution for anastomotic leakage for the low level of colorectal anastomosis.

Abstract
BACKGROUND The utilisation and consequences of standardised operative procedures may importantly differ between different healthcare systems. This is the first investigation comparing the treatment and outcome of femoral shaft fractures stabilised with an identical implant between trauma centres in 2 continents (Europe, EU and South Africa, SA). METHODS Following standardised introduction of the technique, the prospective, observational multicentre study enrolled 175 patients who underwent intramedullary fracture fixation using the antegrade femoral nail (AFN) for femoral shaft fractures. Eleven EU hospitals recruited 86 patients and 1 SA centre 89 patients in the study period. Comparison of epidemiologic data, operative characteristics as well as subjective (e.g., pain, SF-36) and objective (e.g., X-ray, range of motion [ROM]) 3-month and 1-year outcomes were performed (p<0.05). RESULTS Compared to EU centres, several significant differences were observed in SA: (1) on average, patients operated on were younger, had less concomitant diseases and had more severe open fractures; (2) operative stabilisation was more often undertaken by young, unsupervised residents, with shorter operating and intraoperative fluoroscopy times; (3) mean hospital stay was shorter, with less recorded complications, but a higher loss to follow-up rate. Non- or malunion rates and subjective outcomes were similar for both groups, with the physical component of the SF-36 at the 1-year follow-up not fully restoring to baseline values. CONCLUSIONS Our investigation demonstrates the importance of several major differences between 2 different regions of the world in the treatment of femoral shaft fractures, despite involving only high level trauma centres and using an identical implant. The intercontinental comparison of results from clinical studies should be interpreted very carefully considering the heterogeneity of populations and clinical settings.
