ABSTRACT
BACKGROUND: Residual lithiasis is the presence of stones in the common bile duct, ignored after one or more biliary interventions. We report an atypical case of chronic symptomatic lithiasis of the lower bile duct occurring 41 years after biliary surgery, managed successfully by ideal choledochotomy. CASE PRESENTATION: A 68-year-old Black African female with several past laparotomies including a cholecystectomy forty-one years ago presented with hepatic colic-type pain that had been intermittent for several years but worsened recently. Her clinical, biological, and imaging test assessments were suggestive of a residual obstructive lithiasis of the lower common bile duct. Through an open right subcostal laparotomy approach, a dilated bile duct of approximately 3 cm was found and managed by transverse choledochotomy in which the stone was extracted in retrograde manner. After confirmation of disobstruction, a primitive bile duct suture without biliary drainage was performed and a tubular drain was positioned under the liver. The postoperative course was uneventful at follow-up of 30 days. CONCLUSION: Residual choledocholithiasis can be avoided. We performed an ideal choledochotomy, of which the follow-up was simple.

INTRODUCTION AND IMPORTANCE: Retrocaval ureter (RCU) is a rare congenital anomaly usually associated with upper urinary tract stasis, in which the ureter itself passes behind the inferior vena cava. RCU is often misdiagnosed and can lead to serious complications related to the upper urinary tract stasis. CASE PRESENTATION: We report the case of a 57-year-old female who presented with 1-year history of intermittent right flank pain, of gradual onset. She was diagnosed with right RCU, with advanced functional deterioration of the kidney, managed by nephrectomy. The postoperative course was uneventful. CLINICAL DISCUSSION: RCU results in varying degrees of hydronephrosis and thus, in a non-specific clinical presentation. Most cases are asymptomatic, discovered only during imaging or surgery for unrelated conditions or at autopsy. A late diagnosis can lead to an obstructive nephropathy which can be very harmful to the kidney. CONCLUSION: RCU is a very rare entity. The diagnosis can sometimes be late in under-medicalized settings, and must be taken into consideration in front of any hydronephrosis associated or not with intermittent flank pain. RCU-related complications can be very serious. Fish hook sign may be absent in case of nonfunctional kidney and must not exclude the diagnosis. Emphasis should be placed on prenatal diagnosis and routine abdominal ultrasound for early detection.
ABSTRACT
Objective: Acute non-traumatic digestive surgical emergencies are a frequent cause of emergency in Africa. We undertook this study to investigate the morbidity and mortality of these patients in Cameroon, a developing country in Central Africa. Patients and methodology: This was an analytical cross-sectional study with prospective data collection, over a period of eight months (November 2019 to July 2020), at the Yaoundé central hospital (Cameroon). The latter is a second category (intermediate) public health facility in the Cameroon health pyramid, mainly welcoming patients without health insurance. All patients operated on for an acute non-traumatic digestive abdomen were included. The patients were followed up until the 12th postoperative week. We used Cox univariate regression to determine factors associated with the occurrence of postoperative complications. The significance threshold retained was 0.05. Results: We collected 120 patients, representing 14.6% of all surgical emergencies. The mean age of the patients was 37.6 ± 13.5 years. Eighty (66.7%) were male with a sex ratio of 2. The two main preoperative diagnoses were acute generalized peritonitis (n = 58 or 48.3%) and intestinal obstruction (n = 38 or 31.7%). The two main etiologies were peptic ulcer perforation (n = 35) and acute appendicitis (n = 24). The delay between the onset of symptoms and consultation was 1.9 day and an average of 36.8 hours elapsed between diagnosis and surgery. During postoperative time the morbidity and mortality rates were 33.3 and 10%, respectively. Postoperative complications were mostly minor according to the Clavien-Dindo classification, with 21 cases of grade I (33.8%) and 12 cases of grade II (19.3%). The main cause of death was sepsis (8 out of 12 cases). We identified seven factors significantly associated with an increased risk of postoperative complications among whom three were modifiable: The consultation delay greater than 72h (p = 0.02), the time between diagnosis and the surgical intervention greater than 48h (p = 0.01) and the operating time greater than 2h (p = 0.05). Conclusion: In our context, the results of the surgical management of acute non-traumatic abdomens of digestive origin are marked by high morbidity and mortality. The possible solutions are: the organization of public awareness campaigns to prompt rapid consultation in the event of acute abdominal pain, the establishment of universal health coverage as well as the improvement of technical platforms.

BACKGROUND: Although surgical site infection (SSI) is one of the most studied healthcare-associated infections, the global burden of SSI after appendectomy remains unknown. OBJECTIVE: We estimated the incidence of SSI after appendectomy at global and regional levels. DESIGN: Systematic review and meta-analysis. PARTICIPANTS: Appendectomy patients. DATA SOURCES: EMBASE, PubMed and Web of Science were searched, with no language restrictions, to identify observational studies and clinical trials published between 1 January 2000 and 30 December 2018 and reporting on the incidence of SSI after appendectomy. A random-effect model meta-analysis served to obtain the pooled incidence of SSI after appendectomy. RESULTS: In total, 226 studies (729 434 participants from 49 countries) were included in the meta-analysis. With regard to methodological quality, 59 (26.1%) studies had low risk of bias, 147 (65.0%) had moderate risk of bias and 20 (8.8%) had high risk of bias. We found an overall incidence of SSI of 7.0 per 100 appendectomies (95% prediction interval: 1.0-17.6), varying from 0 to 37.4 per 100 appendectomies. A subgroup analysis to identify sources of heterogeneity showed that the incidence varied from 5.8 in Europe to 12.6 per 100 appendectomies in Africa (p<0.0001). The incidence of SSI after appendectomy increased when the level of income decreased, from 6.2 in high-income countries to 11.1 per 100 appendectomies in low-income countries (p=0.015). Open appendectomy (11.0 per 100 surgical procedures) was found to have a higher incidence of SSI compared with laparoscopy (4.6 per 100 appendectomies) (p=0.0002). CONCLUSION: This study suggests a high burden of SSI after appendectomy in some regions (especially Africa) and in low-income countries. Strategies are needed to implement and disseminate the WHO guidelines to decrease the burden of SSI after appendectomy in these regions. PROSPERO REGISTRATION NUMBER: CRD42017075257.

INTRODUCTION: in sub-Saharan Africa, there is scare published data on cancer in general and gastric cancer in particular. METHODS: we conducted a multicenter retrospective analysis of the medical records of patients followed for gastric cancer in 5 hospital departments in the city of Yaoundé (Cameroon) over 6 years. RESULTS: we recorded a total of 120 patients with a mean age of 53.4 ± 13.7 years. There were 62 females (51.7%). The most common risk factors for gastric cancer in our patients was Helicobacter pylori infection (59 cases, 49.1%). Seventy-six patients (63.3%) consulted within 1 to 6 months of symptoms on set at the forefront of which chronic epigastralgia (74.1%). At endoscopy, the tumor was mostly located at the antrum and was locally advanced or metastatic in 25.8% and 58.4 of cases respectively. Adenocarcinoma was the main histologic type found in 105 (87.5%) cases. Curative treatment could only be implemented in 26.7% of patients. We noted a total of 85 deaths (70.8%) with a mean survival time of 5.91 ± 7.51 months. Survival rate at 3 and 5 years was 10.1% and 4.6%, respectively. On multivariable analysis, variables independently associated with overall survival included: WHO stage 3 performance status (p = 0.042), palpable epigastric mass on examination (p = 0.042), pyloric localization (p = 0.007), and liver metastasis (p = 0.012). CONCLUSION: clinical epidemiology of gastric cancer in our study is comparable to those of other African studies with a predominance of locally advanced/metastatic forms. Prognosis is grim with diagnostic delay behind all of the identified mortality risk factors.

BACKGROUND: Intestinal parasitic infections are among the most common communicable diseases worldwide, particularly in developing countries. Human immunodeficiency virus (HIV) causes dysregulation of the immune system through the depletion of CD4+ T lymphocytes which gives rise to opportunistic infections. METHODOLOGY: A cross-sectional study was conducted from January to October 2018. Stool and blood samples were collected from participants aged 1 to 19. Stool samples were analyzed for intestinal parasites. Blood samples were analyzed for HIV and CD4 + T cell counts. RESULTS: Out of 214 children enrolled, 119 (55.6%) were HIV infected and 95 (44.4%) were HIV non-infected. All infected children were on antiretroviral treatment (ART). The prevalence of intestinal parasites was 20.2% in HIV infected and 15.8% in non-infected children. Among the 119 HIV infected children, 33 (27.7%) of them had a CD4+ T cell count less than 500 cells/mm3, and amongst them 5.9% had CD4+ T cell count less than 200 cells/mm3. Among HIV infected children, Cryptosporidium spp. was frequently detected, 7/119 (5.9%), followed by Giardia lamblia 5/119 (4.2%) then Blastocystis hominis 3/119 (2.5%) and Entamoeba coli 3/119 (2.5%). Participants on ART and prophylactic co-trimoxazole for >10 years had little or no parasite infestation. CONCLUSIONS: Although ART treatment in combination with prophylactic co-trimoxazole reduces the risk of parasitic infection, 20.2% of HIV infected children harbored intestinal parasites including Cryptosporidium spp. Stool analysis may be routinely carried out in order to treat detected cases of opportunistic parasites and such improve more on the life quality of HIV infected children.

BACKGROUND: Mesenteric cysts are rare abdominal benign tumours with an incidence of 1:100.000-250.000 surgical admissions located in the mesentery. Theirs presentations may range from incidental asymptomatic discovery during imaging to non-specific abdominal symptoms. CASE PRESENTATION: We present the case of a 46 year old female who presented with 9 months history of progressive abdominal distension. CT scan showed a giant abdominal mass. After the necessary preoperative work up, a midline incision laparotomy was performed. Intraoperative findings were a mesenteric cyst originates from the transverse mesocolon. The cyst weighed 16 kg and histopathology analyses confirmed a lymphangioma mesenteric cyst. DISCUSSION: In low incomes countries like our own, the interval between the onset of symptoms and consultation is often significant, leading to unusual and sometimes spectacular presentations at the time of diagnosis. To our knowledge, it is the heaviest mesenteric cyst reported in the literature to date. CONCLUSION: Mesenteric cysts may present as giant abdominal masses. The publication of this atypical case is a plea for us for the establishment of universal health coverage in our country in particular and in Africa in general.
ABSTRACT
INTRODUCTION: Renal replacement therapy in end-stage kidney disease relies on dialysis in low-income countries. This maintenance treatment needs a reliable vascular access and is done through central venous catheter or creation of A-V fistulas. Several types of A-V fistulas can be done but due to some individual conditions, those possibilities may be exhausted rapidly. CASE PRESENTATION: A 31â¯year old female was diagnosed with an end stage renal disease for which she was prescribed maintenance dialysis. She first denied her condition and went to traditional healer. After some months her clinical state worsened and she was dialyse with catheter and refer to us for A-V fistula construction. The first two attempts on the forearm failed and we found small radial artery both proximally and distally on the left forearm. We finally did a left brachiocephalic fistula with initial retrograde flow on the median cubital vein. DISCUSSION: Despite arm base fistula may be theoretically easy to build because of bigger size vessels, brachiobasilic fistula may be less effective due to difficult venipuncture. Brachiocephalic fistula through median cubital vein may be more effective option with no further procedure needed. CONCLUSION: Brachiocephalic fistula should be considered as option in vascular access especially when a reliable option is needed after previous attempt failure.
ABSTRACT
BACKGROUND: Tetanus is a severe infectious disease that can lead to death. The clinical manifestations are due to an exotoxin secreted by Clostridium tetani, a spore-producing Gram-positive bacillus. The penetration of the germ is made through a skin opening, independently of the size of the wound. CASE PRESENTATION: A 13-year-old black African boy of the Bantu ethnic group with unknown tetanus vaccination status presented to our pediatric emergency room for the management of chest and vertebral pains which started a few days after traditional treatment by scarification and herbal and leaf ointment. The treatment was initiated by a traditional healer and indicated for a closed fracture of our patient's left forearm sustained during a fight. The diagnosis of generalized tetanus was made on the basis of generalized contractures with opisthotonus, trismus, and autonomic nervous system dysfunction. Despite prompt intensive care management, he died a few hours after admission. CONCLUSION: This case emphasizes the permanent threat of tetanus in our environment especially after cultural and traditional acts like scarification that in this specific case was for a therapeutic purpose.

Lumbar hernias are rare conditions and about 300 cases have been reported since the first description by Barbette in 1672. Therefore strangulation or incarceration are also exceptionally encountered. We present a 62 -year-old-man who had strangulated left lumbar hernia and consequent mechanical small-bowel obstruction, alongside with a non strangulated right lumbar hernia. Through a median laparotomy, an intestinal necrosis was found. A bowel resection with end to end anastomosis was performed and the lumbar hernias were repaired on both sides. The recovery was uneventfull. To the best of our knowlwdge thanks to the litterature review presented here, this is the 19th case of incarcerated or strangulated spontaneous lumbar hernia described in the surgical litterature since 1889.
ABSTRACT
To the best of our knowledge there is no reported case of Meckel's diverticulum (MD) in Cameroon. The prevalence of MD in the general population is 2-3 %. The aim of this paper is to recapitulate the role of this pathology in acute abdomens and abdominal pain of uncertain aetiology in young patients and to review the medical literature.
ABSTRACT
BACKGROUND: Retained abdominal sponge after surgery is a quite rare condition which can have heavy medico-legal consequences; its frequency is generally underestimated. Few reports of these conditions are available in African environment with specific technical and medico-legal background. We present our local experience of retained sponges after abdominal surgery and review current literature. METHOD: A retrospective analysis of the medical files of 14 consecutive patients with a retained surgical sponge after abdominal and urological surgery. RESULTS: The incidence was 1every 677 abdominal operations; no metallic foreign body described, only sponges; the female sex predominated with 10/14 patients. 85.71% of retained sponge occurred after an emergency procedure and 64.28% were gynecological or obstetrical procedures. Most cases presented as intestinal obstruction, localized persistent pain or abdominal mass and pre-operative diagnosis could be done only in 28.57% of cases. A falsely correct sponge count was reported in 71.42% of cases 92.85% of patients were re-operated and the morbidity was low; no death was reported. None of our cases ended in a medico-legal claim despite proper counseling. CONCLUSION: The incidence of retained sponge might be significantly higher in an environment with reduced medico-legal threat; most cases of retained sponges are still related to human errors; the incidence will probably be reduced by a greater awareness about the condition.
