Mucocoele of the appendix.

Introduction: Mucocoele of the appendix occurs in 0.2-0.7% of people in the world without any well-defined clinical symptoms. It occurs when there is an accumulation of mucous in the lumen of the appendix. Case Presentation: We present three cases: a 48-year-old male admitted to the emergency room with a one-day history of right iliac fossa pain. Abdominal examination was suggestive of acute appendicitis. The initial abdominal computerised tomography scan was reported as being unremarkable. At surgery, a firm tumour of the appendix was found, and a limited right hemicolectomy was done. Histopathology confirmed a mucocoele of the appendix with borderline mucinous histology.The second case is a 63-year-old man who presented with a one-year history of abdominal distension and weight loss. Previous abdominal ultrasound was suggestive of liver cirrhosis with significant ascitic fluid. Abdominal magnetic resonance imaging found an appendix mucocoele with infiltration of the omentum and scalloping of the liver surface suggestive of pseudomyxoma peritonei. A percutaneous biopsy of the omental mass confirmed metastatic mucinous adenocarcinoma of the appendix.The third case is a 68-year-old man who, during an annual medical check-up, had an incidental finding of a cystic right iliac fossa mass on ultrasound, confirmed on abdominopelvic computerised tomography scan to be an appendix mucocele. He had laparoscopic appendicectomy. The histopathological diagnosis confirmed a mucinous cystadenoma of the appendix. Conclusion: Preoperative diagnosis of appendiceal mucocoele is difficult and commonly discovered intraoperatively. The prognosis is good for the histologically benign type, but it is poor when malignant or peritoneal lesions are present. Funding: None declared.

Quality of Life after Mastectomy with or without Breast Reconstruction and Breast-Conserving Surgery in Breast Cancer Survivors: A Cross-Sectional Study at a Tertiary Hospital in Ghana.

(1) Background: Breast cancer is the leading malignancy worldwide, and in Ghana, it has a poor overall survival rate. However, approximately 50% of cases are cases of early-stage disease, and with advances in breast cancer treatment and improvements in survival, quality of life (QOL) is becoming as important as the treatment of the disease. (2) Methodology: This was a cross-sectional study of survivors who had breast-conserving surgery (BCS), mastectomy only (M) and mastectomy with breast reconstruction (BRS) from 2016 to 2020 at a tertiary hospital in Ghana, comparatively assessing their QOL using EORTC QLQ C-30 and EORTC QLQ BR-23. (3) Results: The study participants had an overall global health status (GHS) median score of 83.3 [IQR: 66.7-91.7] with no significant differences between the surgery types. The BRS group had statistically significant lower median scores for the functional scale (82.8 and 51.0) and the highest scores for the symptomatic scale (15.7 and 16.5). Body image was significantly lowest for the BRS group (83.3) [68.8-91.7] and highest (100) [91.7-100] for the BCS group (p < 0.001). (4) Conclusion: There is a need to develop support systems tailored at improving the QOL of breast cancer survivors taking into consideration the type of surgery performed.

The Prevalence and Management Outcomes of Diverticular Disease in a Tertiary Facility in Ghana.

Background: Diverticular disease of the colon, previously believed to be rare among Africans, is now an emerging disease entity in many African countries. The increasing morbidity and varied presentations are associated with this. Objectives: To determine the prevalence of diverticular disease among patients who underwent lower gastrointestinal endoscopies over a 5-year period and evaluate the common presentations, interventions, and treatment outcomes at the Korle-Bu Teaching Hospital (KBTH), Ghana. Materials and Methods: This was a retrospective cross-sectional study of patients who underwent either a colonoscopy or proctosigmoidoscopy between January 2017 and December 2021, at the KBTH. The records of patients admitted for complications of diverticular disease over the same period were also reviewed. Results: A total of 4266 patients underwent lower gastrointestinal endoscopy over the study period. Out of this, 380 were diagnosed with diverticular disease giving a prevalence of 8.91%. This comprised 58.95% male and 41.05% female. Their mean age was 67.02 (standard deviation ± 11.45). The age ranged from 26 to 95 years with a median of 67. Sixty-seven patients with 88 episodes of admission were managed for complications. The average age was 69.26 (SD ± 13.28) and ranged from 40 to 98 years with an interquartile range of 20 years. Complications were predominantly bleeding diverticular disease (94.32%), whereas 5.6% presented with diverticulitis. Ninety percent were managed conservatively, and 10% had surgical intervention. Conclusion: This study concludes that the prevalence of diverticular disease among Ghanaians undergoing lower gastrointestinal endoscopy is still low and bleeding is the commonest indication for admission which is mostly managed conservatively.

Cross-Sectional Study for Investigation of the Association Between Modifiable Risk Factors and Gastrointestinal Cancers at a Tertiary Hospital in Ghana.

BACKGROUND: Malignancies affecting the gastrointestinal tract are among the principal threats to global public health. In Ghana, these cancers are responsible for a significant number of hospitalizations and mortalities at major health facilities across the country. The increasing incidence of these malignancies necessitates an investigation of the association between lifestyle (modifiable risk factors) and these disorders. MAIN OBJECTIVE: To determine the association between lifestyle and gastrointestinal cancers of patients attending the Korle Bu Teaching Hospital (KBTH). STUDY DESIGN: This was a cross-sectional prospective study where demographic data were obtained from consenting patients diagnosed with gastrointestinal cancer at the oncology and surgical clinics of the KBTH. Diagnostic investigations, gastrointestinal cancer phenotype, year of diagnosis and treatment(s) received were also obtained from the participants. Information on smoking status, alcohol consumption, sources of dietary proteins, daily intake of water, and frequency of fruit intake were also obtained from the participants. Odds ratio and P-values were determined to ascertain whether there might be a significant association between gastrointestinal cancers and specified lifestyle. RESULTS: Colorectal cancers were the most prevalent form of gastrointestinal cancers among the participants. Alcohol consumption or smoking habits were not significantly associated with onset of gastrointestinal cancers among the study participants. There was a significant association but weak correlation between red meat consumption and the colorectal cancer. CONCLUSION: This study shows consumption of red meat to be a modifiable risk factor that is associated with lower gastrointestinal cancers in the study participants. Further longitudinal studies using large number of participants is needed for confirming the observations from this current study.

Morbidity and oncological outcomes after intersphincteric resection of the rectum for low-lying rectal cancer: experience of a single center in a lower-middle-income country.

BACKGROUND: Intersphincteric resection (ISR) of the rectum for low-lying rectal cancer with colo-anal anastomosis was introduced years ago, allowing for bowel continuity, and avoiding permanent stomas. The colorectal unit of Korle Bu Teaching Hospital adopted this procedure in 2014 when indicated, for the management of rectal cancers, where hitherto, abdominoperineal resection of the rectum with a permanent stoma was indicated. This study aimed to assess morbidity, mortality, and oncological outcomes associated with ISR of the rectum and determine the factors contributing to these. METHODS: This was an observational study from prospectively stored data. All patients who underwent intersphincteric resection of the rectum due to low-lying rectal cancer from July 2014 to June 2021 were included in the study, and their records were assessed for intra-operative and 30-day postoperative complications, as well as mortality and their related risk factors and their oncological outcomes in terms of local recurrence at one year. RESULTS: 102 patients were included in this analysis. Six percent (6/102) of patients had intra-operative complications, including bleeding, and 41% (42/102) had 30-day postoperative complications, which were associated with pelvic side wall attachment of tumor and intra-op complications. Mortality risk was 12.7% (13/102) in the early postoperative period, and nine patients had a local recurrence within the first year of surgery. CONCLUSION: There is a high risk of early postoperative morbidity and mortality after intersphincteric resection of the rectum in our setting. The oncological outcomes are favorable in a population that abhors a permanent colostomy.

Bacterial Contamination of Surgical Instruments Used at the Surgery Department of a Major Teaching Hospital in a Resource-Limited Country: An Observational Study.

Surgical instruments, be they disposable or reusable, are essential in any surgical procedure. Reusable surgical instruments should be properly sterilized or disinfected before use. However, the protocols are not always followed accordingly. This results in sterilization and disinfection failures, leading to a possible increase in the incidence of surgical site infections. This observational study report on bacterial contaminants identified instruments used for surgical procedures in a major teaching hospital in a resource-limited country. In total, 207 pre-sterilized surgical instruments and instrument parts used at three units-the general surgical theater, and the gastrointestinal (GI) endoscopy and urology endoscopy (uro-endoscopy) units-within the surgical department were randomly sampled and examined for bacterial contamination. Bacteria isolates were identified, and their antimicrobial susceptibility patterns were determined. Bacteria isolates that were identified included Citrobacter spp., Citrobacter freundii, Bacillus cereus, Staphylococcus hominis, and Staphylococcus aureus. Bacillus cereus was the most predominant bacteria isolated (30/61, 49.1%), and Staphylococcus hominis the least (1/61, 1.6%). In terms of the number of isolates from the three units examined, the uro-endoscopy unit recorded the highest followed by the general surgical theater and the GI endoscopy. However, there was no association between the various units and bacteria isolated, and no significant difference between the number of isolates among the various units (p = 0.9467, χ2 = 0.1095). In this study, even though CFU per device or device part counted was less than 20, bacteria isolated from the instruments used for a surgical procedure is of great concern considering that the setting of the study is a major teaching hospital. Multi-drug resistance was observed in almost all the isolated bacteria. Sterilization processes should be strictly adhered to, taking into consideration the length and temperature in order to reduce the risk of using contaminated instruments in these environments. It is therefore recommended that similar studies should be carried out in surgical departments at different levels of hospitals to ascertain the extent of this problem.

Mucinous adenocarcinoma of a tailgut cyst.

A tailgut cyst is a rare congenital lesion that develops from a residual posterior remnant of the intestine and presents as a mass in the presacral space. They are generally asymptomatic or have atypical symptoms, are usually benign but may rarely become malignant. We report a case of a 37-year-old female who initially presented to the Surgical Department of Korle Bu Teaching Hospital, Accra, Ghana with a malignant tailgut cyst after having repeated surgical procedures for recurrent perianal infective pathologies but still had persistence of symptoms. The lesion was initially excised and found to be a dermoid cyst histologically. The mass recurred after a year and had a re-excision; the lesion was diagnosed histologically as mucinous adenocarcinoma. This report emphasizes the different forms of presentation of a patient with a tailgut cyst and the possibility of malignant transformation, as well as the presentation of this tailgut cyst which can be diagnosed using radiological investigations and histological findings.

Clinicopathological determinants of recurrence after surgical treatment of fistula-in-ano in a Ghanaian teaching hospital.

AIM: The aim of this work is to describe the clinicopathological and surgical aspects of fistula-in-ano and assess the risks associated with recurrence of the disease in a Ghanaian teaching hospital. METHOD: This was a retrospective observational study assessing all fistula-in-ano surgeries performed at the Korle Bu Teaching hospital from January 2014 to January 2021 that had completed follow up of at least 3 months after wound healing. Demographic, clinical, pathological and surgical data were extracted from patient records. Logistic regression analysis was used to test for association between these variables and recurrence. RESULTS: A total of 105 patients underwent 124 fistula surgeries. Their median age was 41 years, the male:female ratio was 4:1 and 12 had comorbidities including human immunodeficiency virus infection and diabetes mellitus. Thirty-one per cent (39/124) of fistulas had previously been operated on. At surgery, 51% (64/124) of fistulas followed a single straight tract, 30% (37/124) a single curved tract and 19% (23/124) had multiple curved tracts. More than half (65/124) were trans-sphincteric, 35% (44/124) suprasphincteric, 10% (12/124) subsphincteric and 2% (3/124) were intersphincteric. Sixty per cent of fistulas were treated with a ligation of intersphincteric fistula tract (74/124), 35% (44/124) a fistulectomy and 5% a fistulotomy. Recurrence after surgery was 22.5% (28/124); this was significantly higher for fistulas with multiple curved tracts (OR 4.153, 95% CI 1.431-12.054, p = 0.012) and fistulas with comorbidities (OR 3.222, 95% CI 1.076-9.647, p = 0.037). CONCLUSION: There was high recurrence after fistula surgery with increased risk for fistulas with multiple tracts and the presence of comorbidities.

Cost-effectiveness analysis of an active 30-day surgical site infection surveillance at a tertiary hospital in Ghana: evidence from HAI-Ghana study.

OBJECTIVE: To assess the cost-effectiveness of an active 30-day surgical site infection (SSI) surveillance mechanism at a referral teaching hospital in Ghana using data from healthcare-associated infection Ghana (HAI-Ghana) study. DESIGN: Before and during intervention study using economic evaluation model to assess the cost-effectiveness of an active 30-day SSI surveillance at a teaching hospital. The intervention involves daily inspection of surgical wound area for 30-day postsurgery with quarterly feedback provided to surgeons. Discharged patients were followed up by phone call on postoperative days 3, 15 and 30 using a recommended surgical wound healing postdischarge questionnaire. SETTING: Korle-Bu Teaching Hospital (KBTH), Ghana. PARTICIPANTS: All prospective patients who underwent surgical procedures at the general surgical unit of the KBTH. MAIN OUTCOME MEASURES: The primary outcome measures were the avoidable SSI morbidity risk and the associated costs from patient and provider perspectives. We also reported three indicators of SSI severity, that is, length of hospital stay (LOS), number of outpatient visits and laboratory tests. The analysis was performed in STATA V.14 and Microsoft Excel. RESULTS: Before-intervention SSI risk was 13.9% (62/446) as opposed to during-intervention 8.4% (49/582), equivalent to a risk difference of 5.5% (95% CI 5.3 to 5.9). SSI mortality risk decreased by 33.3% during the intervention while SSI-attributable LOS decreased by 32.6%. Furthermore, the mean SSI-attributable patient direct and indirect medical cost declined by 12.1% during intervention while the hospital costs reduced by 19.1%. The intervention led to an estimated incremental cost-effectiveness ratio of US$4196 savings per SSI episode avoided. At a national scale, this could be equivalent to a US$60 162 248 cost advantage annually. CONCLUSION: The intervention is a simple, cost-effective, sustainable and adaptable strategy that may interest policymakers and health institutions interested in reducing SSI.

Anorectal malignant mucosal melanoma.

Anorectal mucosal melanoma (AMM) is a rare, aggressive malignancy. The symptoms of AMM mimic common benign conditions in the anus, such as haemorrhoids; hence diagnosis is often made late, a third of patients having metastasis at first presentation. Surgical resection remains the standard of treatment, and adjuvant therapy is varied, including immunotherapy, brachytherapy, and chemotherapy. The prognosis is poor, with a 5-year survival of 20%. A 65year old woman presented with a five-year history of symptoms suggestive of haemorrhoids and was diagnosed with a malignant anorectal mucosal melanoma after symptoms worsened and further investigation was performed. She underwent surgical resection and is currently receiving adjuvant therapy. The prognosis of AMM, the lack of consensus on the treatment regimen to date, and the need for a high index of suspicion for early diagnosis are discussed. Funding: None declared.

Clinical implications of restrictions in criteria for defining surgical site infections after mastectomy.

More than 50% of women with clinically apparent infection after mastectomy did not meet the 2020 National Healthcare Safety Network (NHSN) definition for surgical site infection (SSI). Implant loss was similar whether the 2020 NHSN SSI definition was met or not, suggesting equivalent adverse outcomes regardless of restriction to the surveillance definition.

High rates of multi-drug resistant gram-negative organisms associated with surgical site infections in a teaching hospital in Ghana.

BACKGROUND: There is limited data to guide the prevention and management of surgical site infections (SSI) in low- and middle-income countries. We prospectively studied aetiological agents associated with SSI and their corresponding antibiotic susceptibility patterns in a tertiary hospital in Ghana. METHODS: As part of a cohort study carried out at the surgical department of the Korle Bu Teaching Hospital (KBTH) from July 2017 to April 2019, wound swabs were collected from patients diagnosed with SSI. Isolates cultured from the wound swabs were identified by MALDI TOF and susceptibility testing was conducted according to EUCAST 2020 guidelines. Clinical data were monitored prospectively. RESULTS: Of 4577 patients, 438 developed an SSI and 352 microbial isolates were cultured. Isolates were predominantly Gram negative (286, 81%), a pattern seen for all kinds of surgery and all wound classes. The most common species included Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus and Acinetobacter baumannii. The majority of organisms were multi-drug resistant including 86% of E. coli, 52% of A. baumannii and 86% of K. pneumoniae; and 65% (17/26) of the cefotaxime-resistant K. pneumoniae were extended spectrum ß-lactamase producing. One of 139 E. coli, 15 of 49 P. aeruginosa, and 6 of 23 A. baumannii were meropenem resistant, but no clonal pattern was found. There was a 1% (5/428) prevalence of methicillin-resistant S. aureus. CONCLUSIONS: The predominance of Gram-negative organisms and the high level of multi-drug resistance indicate a need to re-evaluate antibiotic prophylaxis and treatment protocols in surgical practice in low- and middle-income countries.

Antibiotic use in surgical units of selected hospitals in Ghana: a multi-centre point prevalence survey.

BACKGROUND: Improper use of antibiotics leads to the emergence of resistant microorganisms as well as drug toxicity, increased healthcare costs, morbidity and mortality. Globally, an estimated 25-68% of hospitalized patients receive suboptimal antibiotic regimes. Information on the extent of this problem in Ghana is currently limited, particularly in surgical units. To strategize for interventions, we estimated the antibiotic use prevalence in surgical departments in a country-wide point prevalence survey (PPS) in Ghana. METHODS: Between October 2016 and December 2016, we conducted a cross-sectional multi-center country-wide PPS. This involved an audit of in-patients' records from all units/departments of ten systematically selected hospitals in Ghana. Data were collected with a standardized questionnaire, adopted from the European Centre for Disease Prevention and Control. In this report, we present data on antibiotic use from the surgical units. RESULTS: Of 2107 eligible patients included in the PPS, 540 patients were identified in surgical units, of which 70.7% (382/540) received antibiotic therapy. A total of 636 antibiotic prescriptions were issued to these surgical patients; 224 (58.6%) for treatment, including 50 for treatment of hospital-acquired infections, and 144 (37.7%) for prophylaxis (medical and surgical). Median duration of antibiotic therapy prior to the survey was 5 days (interquartile range (IQR): 3-8 days). Surgical prophylaxis was administered for longer than the recommended one day in 107 of 144 (88.4%) patients. The choice of antibiotics was largely similar for community- and hospital-acquired infections as well as for prophylaxis. Only 3.7% of patients had microbiological analysis done on clinical samples. CONCLUSION: We found a high prevalence of antibiotic use, with the choice of antibiotics, in some cases, inconsistent with the country's treatment guidelines. Antibiotics were administered for long duration including antibiotics for prophylactic purposes and the majority was started without supporting microbiological analysis. Prescription practices that encourage rational use of antibiotics guided by microbiology and enforcement of antibiotic policy guidelines should be the target for future interventions.

Antibiotic prescribing in paediatric inpatients in Ghana: a multi-centre point prevalence survey.

BACKGROUND: Excessive and inappropriate use of antibiotics in hospitalised patients contributes to the development and spread of antibiotic resistance. Implementing a stewardship programme to curb the problem requires information on antibiotic use. This study describes a multicentre point prevalence of antibiotic use among paediatric inpatients in Ghana. METHODS: Data were extracted from a multicentre point prevalence survey of hospital acquired infections in Ghana. Data were collected between September 2016 and December 2016 from ten hospitals through inpatient folder and chart reviews using European Centre for Disease Control (ECDC) adapted data collection instrument. From each site, data were collected within a 12-h period (8 am to 8 pm) by a primary team of research investigators and a select group of health professionals from each participating hospital. RESULTS: Among 716 paediatric inpatients, 506 (70.6%; 95% confidence interval (CI): 67.2 to 74.0%) were on antibiotics. A significant proportion of antibiotics (82.9%) was prescribed for infants compared to neonates (63.9%) and adolescents (60.0%). The majority of patients (n = 251, 49.6%) were prescribed two antibiotics at the time of the survey. The top five classes of antibiotics prescribed were third generation cephalosporins (n = 154, 18.5%) aminoglycosides (n = 149, 17.9%), second generation cephalosporins (n = 103,12.4%), beta lactam resistant penicillins (n = 83, 10.0%) and nitroimidazoles (n = 82, 9.9%). The majority of antibiotics (n = 508, 61.0%) were prescribed for community acquired infections. The top three agents for managing community acquired infections were ceftriaxone (n = 97, 19.1%), gentamicin (n = 85, 16.7%) and cefuroxime (n = 73, 14.4%). CONCLUSION: This study points to high use of antibiotics among paediatric inpatients in Ghana. Cephalosporin use may offer an important target for reduction through antibiotic stewardship programmes.

The burden and characteristics of peripheral arterial disease in patients undergoing amputation in Korle Bu Teaching Hospital, Accra, Ghana.

BACKGROUND: To determine the prevalence of Peripheral Arterial Disease (PAD) and associated risk factors in patients undergoing amputation at the Korle Bu Teaching Hospital (KBTH), Accra, Ghana. OBJECTIVES: A cross- sectional study of all patients undergoing lower extremity amputation at the Department of Surgery, KBTH. MATERIALS: A coded questionnaire was used to ascertain risk factors for PAD. The Edinburgh Claudication Questionnaire was used to determine symptomatic PAD and a 5 mmHz hand held Summit® Doppler together with an Accoson ® sphygmomanometer was used to determine PAD and its severity. METHOD: Clinical diagnosis of symptomatic PAD was made using a symptom-based questionnaire and signs of PAD determined by measuring the ankle brachial pressure index (ABPI) by means of a handheld Doppler and sphygmomanometer. Risk factors were determined using the coded questionnaire and related to the occurrence and severity of PAD. RESULTS: The prevalence of PAD among recruited participants was 71%. Twenty-eight per cent of participants with PAD in the index limb also showed signs of PAD in the other limb. The diagnosis of PAD was made in 71%, using ABPI, and 13%, using ECQ. Twenty-seven per cent of patient with hypertension, seventeen per cent with diabetes and all patients with hypercholesterolemia were not on any form of medication. CONCLUSION: There is a high prevalence of PAD among patients undergoing lower extremity amputation at the KBTH. The majority of PAD patients presented with moderate to severe PAD. Instituting measures to identify and control risk factors of PAD may reduce this high burden. FUNDING: Not declared. FUNDING SOURCE: Authors funded the study.
