Population-based rates of hernia surgery in Ghana.

PURPOSE: To estimate the population-based annual rate of hernia surgery in Ghana, so as to better define the met and unmet need and to identify opportunities to decrease the unmet need. METHODS: Data on operations performed from June 2014 to May 2015 were obtained from representative samples of 48 of 124 district (first-level) hospitals, 9 of 11 regional (referral) hospitals, and 3 of 5 tertiary hospitals, and scaled-up to nationwide estimates. Rates of hernia surgery were compared to previously published annual incidence of symptomatic hernia in Ghana (210/100,000 population) and to published annual rates of hernia surgery in high-income countries (120-275/100,000). RESULTS: Estimated 17,418 [95% uncertainty interval (UI) 8154-26,683] hernia operations were performed nationally. The annual rate of hernia operations was 65 operations/100,000 population (95% UI 30.2-99.0). The rate was considerably less than the annual incidence of new symptomatic hernia or rates of hernia surgery in high-income countries. Hernia operations represented 7.5% of all operations. Most hernia operations (74%) were performed at district hospitals. Most district hospitals (54%) did not have fully trained surgeons, but nonetheless performed 38% of district-level hernia operations. CONCLUSIONS: The rate of hernia operations fell short of estimated need. Most hernia repairs were performed at district hospitals, many without fully trained surgeons. Future global surgery benchmarking needs to address both overall surgical rates as well as rates for specific highly important operations. Countries can strengthen their planning for surgical care by defining their total, met, and unmet need for hernia surgery.

Assessment of risk of peripheral vascular disease and vascular care capacity in low- and middle-income countries.

BACKGROUND: This study aimed to describe national peripheral vascular disease (PVD) risk and health burden, and vascular care capacity in Ghana. The gap between PVD burden and vascular care capacity in low- and middle-income countries was defined, and capacity improvement priorities were identified. METHODS: Data to estimate PVD risk factor burden were obtained from the World Health Organization Study on Global Ageing and Adult Health (SAGE), Ghana, and the Institute of Health Metrics and Evaluation Global Burden of Disease (IHME GBD) database. In addition, a novel nationwide assessment of vascular care capacity was performed, with 20 vascular care items assessed at 40 hospitals in Ghana. Factors contributing to specific item deficiency were described. RESULTS: From the SAGE database, there were 4305 respondents aged at least 50 years with data to estimate PVD risk. Of these, 57·4 per cent were at moderate to risk high of PVD with at least three risk factors; extrapolating nationally, the estimate was 1 654 557 people. Based on IHME GBD data, the estimated disability-adjusted life-years incurred from PVD increased fivefold from 1990 to 2010 (from 6·3 to 31·7 per 100 000 persons respectively). Vascular care capacity assessment demonstrated marked deficiencies in items for diagnosis, and in perioperative and vascular surgical care. Deficiencies were most often due to absence of equipment, lack of training and technology breakage. CONCLUSION: Risk factor reduction and management as well as optimization of current resources are paramount to avoid the large burden of PVD falling on healthcare systems in low- and middle-income countries. These countries are not well equipped to handle vascular surgical care, and rapid development of such capacity would be difficult and expensive.

Incidence, characteristics and risk factors for household and neighbourhood injury among young children in semiurban Ghana: a population-based household survey.

BACKGROUND: There are few population-based studies on household child injury in African countries. OBJECTIVES: To determine the incidence, characteristics and risk factors of household and neighbourhood injury among children in semiurban communities in Kumasi, Ghana. METHODS: We conducted a cross-sectional population-weighted survey of 200 randomly selected caregivers of children under 18, representing 6801 households. Caregivers were interviewed about moderate to severe childhood injuries occurring within the past 6 months, for which the child staying home from school or activity, and/or required medical care. Multivariable logistic regression was used to identify factors associated with injury risk. RESULTS: Annual injury incidence was 593.5 injuries per 1000 children. Common causes of injury were falls (315.7 injuries per 1000 children), followed by cuts/lacerations and burns. Most injuries (93.8%) were of moderate severity. Children whose caregivers were hourly workers (AOR=1.97; 95% CI 1.06 to 3.68) had increased odds of sustaining an injury compared to those of unemployed caregivers. Girls had decreased odds of injury (AOR=0.59; 95% CI 0.39 to 0.91). Cooking outdoors (AOR=0.45; 95% CI 0.27 to 0.76) and presence of cabinet/cupboards (AOR=0.41; 95% CI 0.24 to 0.70) in the house were protective. Among children under 5 years of age, living in uncompleted accommodation was associated with higher odds of injury compared with living in a rented single room (AOR=3.67; 95% CI 1.17 to 11.48). CONCLUSIONS: The incidence of household and neighbourhood child injury is high in semiurban Kumasi. We identified several novel injury risk factors (hourly work, younger children) and protective factors (cooking outdoors, presence of cabinet/cupboards). These data may identify priorities for household injury prevention.

STARTING A LAPAROSCOPIC SURGERY PROGRAMME IN THE SECOND LARGEST TEACHING HOSPITAL IN GHANA.

BACKGROUND: Komfo Anokye Teaching Hospital (KATH) is the second largest hospital in Ghana. Two years have elapsed after performance of the first laparoscopic cholecystectomy. OBJECTIVES: To examine our experience and lessons learned. DESIGN: Retrospective review. SETTING: Komfo Anokye Teaching Hospital (KATH). SUBJECTS: We reviewed leadership support, the role of a surgeon champion, training of physician and OR staff, influence of surgeons from outside Ghana and equipment status. The results of laparoscopic cholecystectomies performed from 2010-2012 were compared with information available from open cholecystectomies over the same period. RESULTS: Evidence of leadership support included equipment purchase and invitation of outside experts yearly from 2008. A KATH surgeon champion was identified in 2010. A dedicated OR team received training and exhibited excellent ownership of equipment preparation. Since 2010, 25 laparoscopic cholecystectomies have been performed, 17 independently by a single surgeon. Average operative time was 1.41 hours and length of stay (LOS) 1.5 days. Conversion rate was 4.0% (1/25). Complication rate was 20.0% (5/25), none involving haemorrhage or injuries to bile ducts or bowel. Median patient satisfaction score was 5 on a scale of 1-5 where 5 is most satisfied. Complication rates and hospital stay were lower than for open cholecystectomy (20.0% vs 34.5%, p > 0.05 and 1.5 days vs 6.6 days, p < 0.001 respectively). Operative times were on average 27 min onger for laparoscopic cholecystectomy (p < 0.01). CONCLUSION: Laparoscopic cholecystectomy at KATH has become a reality with less complications rates, shorter LOS, and trends towards improved patient satisfaction. Expanding laparoscopic surgery in Ghana requires its inclusion into residency training programmes and public education about its benefits for both patients and physicians.

GIANT SOLITARY NEUROFIBROMA IN THE GLUTEAL AREA OF A PATIENT WITHOUT NEUROFIBROMATOSIS.

Neurofibromas are benign tumours arising from neurons andperineural cells. Although they are common inneurofibromatosis, occasionally solitary neurofibromas may occur. A rare case of solitary neurofibroma presenting as a giant gluteal mass in a male patient without a personal or family history of neurofibromatosis is presented. Pre-operative imaging gave useful information about the extent of the mass which was then totally excised with histology revealing a non-plexiform neurofibroma. Distinguishing between isolated neurofibromas and those associated with neurofibromatosis is important because the treatment and prognosis differ greatly with the former having a good prognosis after total excision.

Gastrointestinal stromal tumour presenting acutely as gastroduodenal intussusception.

INTRODUCTION: Gastrointestinal stromal tumours (GISTs) are uncommon tumours of the gastrointestinal (GI) tract. We report a case of a gastric GIST that presented acutely as a gastroduodenal intussusception. CASE PRESENTATION: A 59-year-old woman presented with a week's history of vomiting anything she swallowed. Physical examination revealed a mildly tender abdomen without guarding or rebound tenderness. An epigastric mass was, however, palpated. Abdominal ultrasonography suggested an intussusception. At laparotomy, a tumour on the anterior wall of the stomach causing intussusception of the stomach into the duodenum was found. After reducing the intussusception, a wedge resection of the tumour was performed, which proved to be a GIST. DISCUSSION: GISTs represent a rare group of neoplasms of the GI tract. Gastric intussusception is a rarely documented condition. Symptoms range from intermittent epigastric pain to sudden onsets of severe pain with vomiting and shock. Pre-operative diagnosis can be difficult and diagnosis cannot be confirmed until surgery. The treatment of choice for localised gastric GIST is surgical resection. CONCLUSION: Although gastroduodenal intussusception, particularly secondary to a GIST, is uncommon, clinicians need to have a high index of suspicion in acutely vomiting patients, especially if they have experienced similar symptoms intermittently in the immediate past.

Hand ischemia caused by solitary humeral exostosis irritating the brachial artery.

A 39-year-old woman presented with ischemia of the left hand. Angiography revealed thrombosis of forearm arteries. Surgical intervention was unsuccessful. CT angiography revealed an exostosis on the distal humerus close to the brachial artery which we believe was the cause of repetitive minor trauma to the brachial artery leading to embolic occlusion of the radial and ulnar arteries. Early diagnosis of the underlying cause is the key to successful treatment of hand ischemia. For patients without risk factors for arterial occlusive disease, imaging of bony structures must be performed in order not to miss the likely cause of an insidious repetitive vascular trauma.

Surgical treatment of peripheral aneurysms in patients with Behcet's disease.

INTRODUCTION: Our aim was to report our experience with 23 patients presenting with 32 peripheral aneurysms secondary to Behcet's disease (BD) and their outcome after vascular surgery. METHODS: The study was retrospective in nature. Except for those presenting with aneurysm rupture, patients underwent surgery after treatment of acute inflammatory lesions. All aneurysms appeared to be pseudo-aneurysms. Graft interposition with polytetrafluoroethylene or saphenous vein was most commonly employed. Postoperatively, all patients were put on immunosuppressive and antiplatelet therapy. Follow-up was done every 6-12 months, complications recorded and managed appropriately. RESULTS: All the patients were males. The mean age at diagnosis of a peripheral aneurysm was 41.0 ± 9 years. There were 17 (53%) femoral, 8 (25%) popliteal, two carotid, two external iliac, two brachial and one internal iliac aneurysms. Fourteen (61%) patients had a single peripheral aneurysm while nine had two. Surgery was performed for all initially presenting 23 aneurysms. Six patients with multiple peripheral aneurysms had surgery for their second asymptomatic aneurysm. The mean follow-up period was 84 ± 62 months. Of 29 aneurysms operated on, 7 (24%) anastomotic pseudo-aneurysms and 11 (38%) graft occlusions developed. Five (22%) patients underwent major lower extremity amputations. Six (26%) mortalities were recorded. CONCLUSION: Surgery for peripheral aneurysms in BD is warranted in many instances. Results of operation can be improved by prolonged monitoring. However, despite all efforts, peripheral aneurysm involvement in BD worsens the prognosis.

Congenital transmesenteric defect causing bowel strangulation in an adult.

INTRODUCTION: Congenital transmesenteric hernias represent a very small group of internal hernias which are uncommon and are a rare cause of intestinal obstruction. Diagnosis is frequently made at surgery. Reports of congenital transmesenteric hernia in the English literature usually involve the pediatric population; adult cases are rarer. CASE REPORT: A 22-year-old man who presented with a day's history of severe abdominal pain but without classic physical examination signs of abdominal obstruction was operated upon on account of increasing abdominal pain and distention associated with shock. Laparotomy revealed a congenital transmesenteric defect through which loops of bowel had herniated and become gangrenous, resulting in resection and end-to-end anastomosis. DISCUSSION: Congenital transmesenteric defects causing internal hernias in adults are rare. Preoperative diagnosis of the condition is difficult, in part, because there are no radiographic or laboratory findings to confirm the suspicion. Misdiagnosis resulting in delayed exploration may lead to small bowel necrosis and subsequent mortality. CONCLUSION: A congenital internal hernia should be considered in a patient with bowel obstruction without previous abdominal surgery, inflammatory abdominal condition, or trauma. We wish to emphasize that, rather than trying to establish a correct diagnosis, the patient's clinical features should lead to early surgery in order to reduce morbidity and possible mortality.

Occlusion of the celiac trunk, the inferior mesenteric artery and stenosis of the superior mesenteric artery in peripheral thrombangiitis obliterans.

Buerger's disease is an inflammatory occlusive disease which commonly involves medium-sized or smaller vessels of extremities. Mesenteric involvement in Buerger's disease is very rare. It can occur at any time during the course of the disease and presents with acute mesenteric ischaemia. In this study, a case of Buerger's disease with mesenteric involvement diagnosed before the onset of acute mesenteric ischaemia and managed endovascularly is reported.

Evaluation of muscle atrophy after axillary lymph node dissection.

INTRODUCTION: Axillary node status is the most important prognostic factor for patients with primary breast carcinoma, making axillary lymph node dissection (ALND) a standard surgical treatment of breast cancer. Postoperative sequelae to ALND is frequently reported. In this study we aimed to find out objectively, how much damage is caused to these nerves during ALND. PATIENTS AND METHODS: A total of 50 breast cancer patients who underwent surgical treatment in our Breast and Endocrine Surgery Unit between March 1998 and July 2004 were included in the study. Surgical treatment of these patients consisted of breast conserving surgery or total mastectomy combined with ALND. To compare operated patients with non-operated patients as a control, only patients who had undergone unilateral surgery were included in the study so that the non-operated side served as the normal control for each patient. All patients had a postoperative review with an anatomical and functional examination at least 6 months after the operation. Computed tomography was then performed and the M. latissimus dorsi (MLD), M. pectoralis major (MPM) and M. serratus anterior (MSA) thicknesses were measured. RESULTS: On physical examination, the aforementioned muscles in all the patients were found to be intact and functional. Sixty-four percent of the operated patients group were found to have various degrees of hypoesthesia. MLD, MPM and MSA amongst the non-operated patients group were found to be significantly thicker than the corresponding muscles amongst operated patients group. CONCLUSION: We conclude that a significant amount of reduction in the thickness of the MLD, MPM and MSA occurs after ALND. Also, sensory deficit occurs, especially on the upper medial portion of the arm, showing damage to the intercostobrachial nerves.

Surgical repair of a giant renal artery aneurysm: a case report.

A case of a giant renal artery aneurysm and multiple small branch aneurysms in a 48-year old man is presented. The largest aneurysm was repaired successfully with kidney preservation. Small branch aneurysms were left alone. Subsequent CT scans 6, 12 and 20 months after the operation revealed the same aneurysms without any increase in size and shape.
