RESUMO
BACKGROUND: Cumulative sum (CUSUM) analysis is a valuable tool for quantifying the learning curve of surgical teams by detecting significant changes in operative length. However, there is limited research evaluating the learning curve of laparoscopic techniques in low-resource settings. The objective of this study is to evaluate the learning curve for laparoscopic appendectomy within a single surgical team in Senegal. METHODS: This was a single-center prospective study conducted from May 1, 2018, to August 31, 2023 of patients who underwent laparoscopic appendectomy at a tertiary care institution in West Africa. The AAST classification was used to describe the severity of appendicitis. Parameters studied included age, sex, operative length, conversion rate, and postoperative outcomes. To quantify the learning curve, CUSUM analysis of operative length was performed. RESULTS: A total of 81 patients were included. The mean age was 26.7 years (range 11-70 years) with a sex ratio of 1.9. Pre-operative severity according to AAST was Grade I in 75.4% (n = 61), Grade III in 7.4% (n = 6), Grade IV in 6.1% (n = 5), and Grade V in 11.1% (n = 9). Conversion occurred in 5 cases (6.1%). The average operative length was 76.8 min (range 30-180 min) and the average length of hospitalization was 2.7 days (range 1-13 days). Morbidity was observed in 3.7% (n = 3) and there were no deaths. The CUSUM analysis showed that a steady operative length was achieved after 28 procedures, with decreasing operative lengths thereafter. CONCLUSION: Surgeons in our setting overcame the learning curve for laparoscopic appendectomy after performing 28 procedures. Moreover, laparoscopic appendectomy is safe and feasible throughout the learning curve. CUSUM analysis should be applied to other laparoscopic procedures and individualized by surgical teams to improve surgical performance and patient outcomes in low-resource settings.

BACKGROUND: Adult mechanical bowel obstruction (AMBO) has been previously reported to be majorly caused by hernias in developing countries. In Nigeria, however, there has been a recent change in pattern with adhesions now being the leading cause. The aim of this systematic review is to examine the changing pattern of the causes, and outcomes of patients managed for AMBO in Nigeria. METHODS: Relevant keywords relating to AMBO were used to conduct a search on PubMed, Web of Science, Google Scholar, and AJOL. The search returned 507 articles, which were subjected to title, abstract, and full text screenings, according to the inclusion and exclusion criteria. This generated 10 articles which were included in the final qualitative synthesis. RESULTS: The total sample size across the 10 studies was 1033. Adhesions, hernias, and intra-abdominal tumors, responsible for 46.25%, 26.31%, and 12.23% of cases respectively, were the major causes of AMBO in Nigeria. 65.6% of cases were managed operatively and 34.4% were managed conservatively. The meta-analysis revealed high morbidity and mortality rates of 31% (95% CI: 17; 44, 5) and 11% (95% CI: 6; 15, 5), respectively, among adult patients managed for mechanical bowel obstruction in Nigeria. CONCLUSIONS: Adhesion, which results predominantly from appendicectomy is the most common cause of AMBO in Nigeria. This is unlike former reports where hernia was the most common cause. Morbidity results majorly from wound infection, recurrent adhesions, and postoperative enterocutaneous fistula. The mortality rate is similar to reports from various West African studies, and it is significantly influenced by surgical intervention time.

BACKGROUND: Minimally invasive surgery, including laparoscopy and robotics, has significantly improved general surgical (GS) practice globally. While robot-assisted GS practice is yet to be adopted in the majority of Africa, laparoscopy has been utilized to improve surgical outcomes. This study aims to review the laparoscopic GS procedures (LGSPs) performed and evaluate outcomes such as conversion to open surgery, morbidity, and mortality in Africa. METHODS: Four databases (PubMed, Google Scholar, WoS, and AJOL) were searched, identifying 8022 publications. Following screening, 40 studies across Africa that reported LGSPs (n ≥ 2) performed and outcomes met the inclusion criteria. A meta-analysis conducted using R statistical software estimated the pooled prevalences with the 95% CI of conversion, morbidity, and mortality. RESULTS: A total of 6381 procedures performed in 15 African countries were analyzed in this study. Majority, 72.89%, of the procedures were performed in Senegal, South Africa, and Nigeria. The major procedures performed were cholecystectomy (37.09%), appendicectomy (33.36%), and diagnostic laparoscopy (9.98%). The meta-analysis revealed a conversion rate of 5% [95% CI: 4, 7]. Adhesion (28.13%), hemorrhage (16.67%), technical difficultly (12.50%), and equipment failure (11.46%) were the predominant indications for conversion. Surgical site infection (42.75%) was the major cause of morbidity. The prevalences of morbidity and mortality were 7% [95% CI: 5, 10] and 0.12% [95% CI: 0, 0.29], respectively. CONCLUSION: A wide range of basic and advanced LGSPs were performed. The outcomes obtained indicate successful implementation of the laparoscopic approach. Importantly, this study serves as a foundational work for further research on minimally invasive surgery in Africa.

INTRODUCTION: Abdominal surgical emergencies remain prevalent in various healthcare settings, particularly in regions with limited access to basic surgical care, such as Africa. The aim of this literature review is to systematically assess publications on abdominal surgical emergencies in adults in sub-Saharan Africa to estimate their prevalence and mortality rate. METHODOLOGY: A systematic review was conducted. The latest search was performed on October 31, 2022. We estimated the pooled prevalence with a 95% confidence interval (CI) for each abdominal surgical emergency, as well as overall postoperative mortality and morbidity rates. RESULTS: A total of 78 studies were included, and 55.1% were single-center retrospective and monocentric studies. The mean age of the patients was 32.5 years, with a sex ratio of 1.94. The prevalence of each abdominal surgical emergency among all of them was as follows: appendicitis: 30.0% (95% CI: 26.1-33.9); bowel obstruction: 28.6% (95% CI: 25.3-31.8); peritonitis: 26.6% (95% CI: 22.2-30.9); strangulated hernias: 13,4% (95% CI: 10,3-16,5) and abdominal trauma: 9.4% (95% CI: 7.5-11.3). The prevalence of complications was as follows: mortality rate: 7.4% (95% CI: 6.0-8.8); overall postoperative morbidity: 24.2% (95% CI: 19.4-29.0); and surgical site infection 14.4% (95% CI: 10.86-18.06). CONCLUSION: Our study revealed a high prevalence of postoperative complications associated with abdominal surgical emergencies in sub-Saharan Africa. More research and efforts should be made to improve access and quality of patient care.

OBJECTIVE: The aim of this review is to clarify the prevalence, pathophysiology and clinical presentation of enuresis and overactive bladder in sickle cell patients. MATERIALS AND METHODS: This narrative review of the literature was conducted in March 2022 by running a search in PubMed, Embase, Scopus and Cochrane databases without publication date limitation, using the following keywords: enuresis or nocturia or overactive bladder or urinary incontinence or bedwetting and sickle cell. RESULTS: Eight cross-sectional studies were included, six of which had a non-sickle cell control population. The prevalence of enuresis in children and adolescents with sickle cell disease ranged from 20.3 to 49.4%. It decreased with age to 2.9% in adult sickle cell patients. Enuresis in sickle cell patients has been attributed to several causes, including lack of urine concentration with nocturnal polyuria, reduced bladder capacity, nocturnal bladder hyperactivity, sleep and/or respiratory disorders are likely causes of enuresis in sickle cell patients. The prevalence of overactive bladder is three times higher in sickle cell patients than in control groups. The latter is also observed three times more frequently in men who have had prior episodes of priapism. CONCLUSION: Enuresis and overactive bladder are common in sickle cell patients. Several mechanisms have been described to try to explain enuresis in sickle cell patients but overactive bladder seems to play a major role. Studies evaluating the efficacy of certain experimentally validated treatments must be carried out to improve the management of these complications which affect the quality of life of sickle cell patients.

INTRODUCTION: The advent of laparoscopy has significantly reduced the morbidity associated with the majority of abdominal surgeries. In Senegal, the first studies evaluating this technique were published in the 1980s. The objective of this systematic review is to assess the evolution of laparoscopy research in Senegal. METHODS: A search of PubMed and Google Scholar was carried out without limit of publication date. The keywords used were "senegal" AND "laparoscop*". Duplicates were removed, and remaining articles were assessed for selection criteria. We included all articles about laparoscopy published in Senegal. The parameters studied in each included article were the place and year of study, average age, sex ratio, assessed indications and results. RESULTS: 41 Studies published between 1984 and 2021 met selection criteria. The average age of patients was 33 years (range 4.7-63). The sex ratio was 0.33. The main indications for laparoscopy according to the studies were: benign gastrointestinal disorders in 11 studies (26.8%), abdominal emergencies in 9 studies (22%), gallbladder surgery in 5 studies (12.2%), benign gynecological pathology in 6 studies (14.6%), malignant gynecological pathology in 2 studies (4.9%), diagnostic laparoscopy in 2 studies (4.9%), groin hernia repair in 2 studies (4.9%) and testicular pathology in 1 study (2.4%). Overall mortality was estimated at 0.9% (95% CI 0.6-1.3) and overall morbidity for all complications was estimated at 5% (95% CI 3.4-6.9). CONCLUSIONS: This systematic review showed a predominance of the laparoscopy publications from the capital in Dakar with favorable outcomes. This technique should be popularized in the different regions of the country and its indications expanded.

INTRODUCTION: Laparoscopy has a clear patient benefit related to postoperative morbidity but may not be as commonly performed in low-and middle-income countries. The decision to convert to laparotomy can be complex and involve factors related to the surgeon, patient, and procedure. The objective of this work is to analyze the factors associated with conversion in laparoscopic surgery in a low-resource setting. METHODS: This is a single-center prospective study of patients who underwent laparoscopic surgery between May 1, 2018 and October 31, 2021. The parameters studied were age, sex, body mass index (BMI), intraoperative complication (e.g., accidental enterotomy, hemorrhage), equipment malfunction (e.g., technical failure of the equipment, break in CO2 supply line), operating time, and conversion rate. RESULTS: A total of 123 laparoscopic surgeries were performed. The average age of patients was 31.2 years (range 11-75). The procedures performed included appendix procedures (48%), followed by gynecological (18.7%), gallbladder (14.6%), digestive (10.56%), and abdominal procedures (4%). The average length of hospitalization was 3 days (range 1-16). Conversion to laparotomy was reported in 8.9% (n = 11) cases. Equipment malfunction was encountered in 9.8% (n = 12) cases. Surgical complications were noted in 11 cases (8.9%). Risk factors for conversion were shown to be BMI > 25 kg/m2 (OR 4.6; p = 0.034), intraoperative complications (OR 12.6; p = 0.028), and equipment malfunction (OR 9.4; p = 0.002). CONCLUSION: A better understanding of the underlying factors associated with high conversion rates, such as overweight/obesity, intraoperative complications, and equipment failure, is the first step toward surgical planning to reduce postoperative morbidity in low-resource settings.

Cystic dysplasia of the testis is characterized by the presence of multiple cysts within the testicular parenchyma. It is a rare benign tumor. It is often accompanied by kidney malformations. There is no consensus on treatment. We report here the case of testicular dysplasia revealed by a torsion of the spermatic cord in an adult. The diagnosis of cystic dysplasia of the testis was made intraoperatively and confirmed by pathology. An orchiectomy was performed. Serum testicular cancer markers were normal postoperatively.
RESUMO
INTRODUCTION: Bezoars are a known cause of complications in Meckel's diverticulum. We present a case in which a bezoar in a Meckel's diverticulum resulted in intestinal obstruction. In addition, we conducted a narrative review to explore the association between Meckel's diverticulum and bezoars. CASE PRESENTATION: We present the case of a 22-year-old patient admitted for bowel obstruction persisting for three days and periumbilical tenderness. Abdominal CT tomography revealed a hyper dense circular structure with a diameter of 2 cm, small bowel distension of 41 mm, and free fluid. During surgical exploration, a Meckel diverticulum was found between the antimesenteric border of the small bowel and posterior wall of the umbilicus. The Meckel diverticulum was resected, and upon examination, it was found to contain a calcified phytobezoar. The postoperative course was uneventful. DISCUSSION: The clinical and paraclinical presentation of bezoars in Meckel's diverticulum is nonspecific and diagnosis remains challenging despite improved diagnostic modalities. The association between Meckel's diverticulum and bezoars is often identified during surgery, as it is difficult to diagnose using CT scans. The choice between laparoscopic and open surgery depends on the patient's situation. CONCLUSION: Diagnosing a bezoar in a Meckel's diverticulum remains challenging. Treatment involves surgery, and the choice of surgical approach depends on the context.
RESUMO
Introduction and importance: Meckel's diverticulum is a rare congenital intestinal anomaly that can sometimes cause serious complications. The authors' aim is to review the literature on this condition by reporting the clinical case of a young adult with Meckel's diverticulum complicated by acute intestinal obstruction. Case presentation: This was a 24-year-old young man, operated on for open bladder stones received for occlusive syndrome. Abdominal computed tomography (CT) suggested a flange occlusion. Surgical exploration found a Meckel's diverticulum creating a flange around the last one. An intestinal resection was performed with direct anastomosis with simple consequences. Clinical discussion: Meckel's diverticulum is a rare congenital intestinal anomaly. It is discovered incidentally or in the face of serious complications such as intestinal obstruction. Intestinal resection with one-stage anastomosis emerges as a standard and safe management approach. Conclusion: A Meckel's diverticulum can be complicated by acute intestinal obstruction mimicking a postoperative flange that can err the diagnosis.
RESUMO
Introduction: Digestive surgical emergencies remains one of the main general surgery activities. Despite the associated mortality rate in low income countries, epidemiologic data about this subject is rare and multicenter studies are even more. We aimed to study an epidemiology of digestive surgical emergencies in Senegal by multicenter protocol. Methods and analysis: it will a prospective multicenter pilot study from May to July 2022. The patients were from General surgery departments of these teaching hospital in Senegal: Dakar Principal Hospital, Aristide le Dantec Hospital, Dalal Jamm hospital and Saint-Louis Regional Hospital. The Schwartz formula was used. We used a proportion of abdominal surgical emergency of 20%. We had a sample size of 246 patients. Ethics and dissemination: this research protocol will be submitted to Ethics committee of four hospital that included. The results of this study can help to get better the management of our digestives emergencies and at the same time improve mortality rate. Highlights: Digestive surgical emergencies is a public health issueBecause of high mortality rate in poorest countries, epidemiological data in Senegal must be knownThese information can help to lower associated mortality.
RESUMO
Pylephlebitis is a thrombotic occlusion of the portal vein or its branches secondary to infection in regions that drain to the portal venous system. Clinical presentation is often atypical, and patients may initially present with non-specific abdominal symptoms. We report a case of pylephlebitis secondary to inflammatory colitis depicted by CT scan in a 35-year-old female admitted for acute abdominal pain associated with vomiting and fever.
RESUMO
Pylephlebitis is a complication of intra-abdominal infections. Its occurrence during cholecystitis is a rare situation. We report the case of a 43-year-old female patient who presented with septic thrombosis of the right portal branch following acute calculous cholecystitis diagnosed on abdominal CT. The clinical evolution was favorable under antibiotic therapy and a cholecystectomy was scheduled.
RESUMO
BACKGROUND: Laparoscopic cholecystectomy is the most common laparoscopic procedure performed in the US and a key component of general surgery training. Surgical trainees frequently access YouTube for educational walkthroughs of surgical procedures. This study aims to evaluate the educational quality of YouTube video walkthroughs on laparoscopic cholecystectomy by using the LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) video assessment tool. METHODS: A YouTube search was conducted using "laparoscopic cholecystectomy." Results were sorted by relevance, and the top 100 videos were gathered. Videos with patient education or concomitant procedures were excluded. Included videos were categorized as Physician (produced by an individual physician), Academic (produced by a university or medical school), Commercial (produced by a surgical company), and Society (produced by a professional surgical society) and were rated by 3 investigators using the LAP-VEGaS video assessment tool (0-18). RESULTS: In all, 33 videos met the selection criteria. The average LAP-VEGaS score was 7.96 ± 3.95, and inter-rater reliability was .86. Academic videos demonstrated a significantly higher mean LAP-VEGaS score than Commercial (10.69 ± 3.54 vs 5.25 ± 2.38, P = .033). Most academic videos failed to provide formal case presentations (63%), patient positioning (50%), intraoperative findings (50%), graphic aids (63%), and operative time (75%). CONCLUSION: This is the first study to evaluate the quality of YouTube video walkthroughs on LC using the LAP-VEGaS tool. Despite demonstrating higher LAP-VEGaS scores than other categories, video walkthroughs provided by academic institutions still lack several essential educational criteria for this procedure, highlighting areas of improvement for educators.

It is well established that access to preventative care, such as breast or cervical cancer screening, can reduce morbidity and mortality. Certain groups may be missed out of these healthcare services, such as women with disabilities, as they face many access barriers due to underlying inequalities and negative attitudes. However, the data have not been reviewed on whether women with disabilities face inequalities in the uptake of these services. A systematic review and meta-analysis were conducted to compare the uptake of breast and cervical cancer screening in women with and without disabilities. A search was conducted in July 2021 across four databases: PubMed, MEDLINE, Global Health, and CINAHL. Quantitative studies comparing the uptake of breast or cervical cancer screening between women with and without disabilities were eligible. Twenty-nine studies were included, all from high-income settings. One third of the 29 studies (34.5%, n = 10) were deemed to have a high risk of bias, and the remainder a low risk of bias. The pooled estimates showed that women with disabilities have 0.78 (95% CI: 0.72-0.84) lower odds of attending breast cancer screening and have 0.63 (95% CI: 0.45-0.88) lower odds of attending cervical cancer screening, compared to women without disabilities. In conclusion, women with disabilities face disparities in receipt of preventative cancer care. There is consequently an urgent need to evaluate and improve the inclusivity of cancer screening programs and thereby prevent avoidable morbidity and mortality.

Pyonephrosis is a suppurative infection of the kidney caused by ureteral obstruction. It can lead to kidney failure, septic shock, and death. Thus, it requires prompt assessment and appropriate management. We report a case of a 63-year-old male with giant pyonephrosis contained 10 liters of pus and spontaneously ruptured in the adjacent muscles. This clinical case illustrates the value of computed tomography scan in the diagnosis and management of an uncommon upper urinary tract infection and its complications.
RESUMO
Introduction: The management of abdominal penetrating trauma remains complex. Between the risk of negative laparotomy and missed visceral injury, laparoscopy is a good alternative. We report 2 cases of abdominal penetrating trauma with colonic injury diagnosed and treated with laparoscopic approach. Observations: The first patient was 15 years old, with no medical history and received at 3 h of a penetrating trauma by stabbing. Hemodynamic status was normal. An exploratory laparoscopy was performed. It objectified a penetration of the peritoneum on the left flank with an injury of the anti-mesenteric edge of the descending colon that was sutured. The second patient was 20 years old, with no history, who had a penetrating trauma of the left iliac fossa by stabbing. Arterial pressure was normal. He was received 6 h after the trauma. An exploratory laparoscopy objectified an injury of 2 cm located at the sigmoid colon which was sutured with a good evolution. Conclusion: Laparoscopy in abdominal wounds is a good option in selected patients. It has a diagnostic and therapeutic importance in colonic injuries. The limits are represented by the possibility of unrecognized visceral lesions that can lead to additional morbidity.
RESUMO
Appendicitis is the first etiology for abdominal surgical emergency. Ascariasis is the most common helminth infection in tropical countries where it is endemic. The ability of intestinal helminths to wander through the digestive system means that it can end up in the appendix lumen and lead to appendicitis by luminal obstruction. However, this presentation is still rarely described in the literature. In fact, most of the diagnoses of roundworm associated with appendicitis are made retrospectively by the discovery of its eggs on the pathological examination of an appendectomy specimen. We report the case of a 7-year-old patient living in a tropical area who consulted for acute right lower quadrant pain. The ultrasound suspected the diagnosis of appendicitis and also revealed multiple intestinal worms including one in contact with the inflamed appendix. Surgical exploration confirmed appendicitis associated with roundworm partly in the appendicular lumen through a perforation.
RESUMO
Lipoma is a benign soft tissue tumour. It is a benign proliferation of mature adipocytes. It is described as giant when its weight exceeds 1 kg or its diameter exceeds 5 cm. Functional and aesthetic impairment may be a major reason for surgical excision. It can be located everywhere, but it mainly occurs in the posterior segment of the chest. We here report a case of giant lipoma of the left posterior-superior segment of the chest.
