Bouveret's syndrome: An old diagnosis. A modern multimodality approach (endoscopic and robotic surgical) of gastric outlet obstruction: Report of two cases.

INTRODUCTION AND IMPORTANCE: Bouveret's syndrome is an uncommon condition characterized by the impaction of a gallstone in the pylorus or duodenum via a cholecysto-enteric fistula causing gastric outlet obstruction. We report two unusual cases of Bouveret's syndrome causing gastric outlet obstruction in two elderly patients. CASE PRESENTATION: Two elderly female patients presented to the surgical assessment unit with features of gastric outlet obstruction. In both cases, an urgent computed tomography (CT) of the abdomen showed pneumobilia, gastric distension, and gallstones impaction at the duodenal bulb. In Patient 1, endoscopic removal of the impacted gallstones was done successfully. She was discharged three days following an uneventful recovery. In Patient 2, an endoscopic removal of a single large gallstone was attempted, which was unsuccessful. She underwent robotic gastrotomy with extraction of the large gallstone with primary repair. She was discharged on 8th postoperative day. CLINICAL DISCUSSION: Treatment options for Bouveret's syndrome include endoscopic management and surgery. The selection of treatment options depends upon factors like the degree of obstruction, the impaction site, number, type or size of gallstones, patient co-morbidities and clinical parameters at presentation, as well as expertise available, both endoscopic and surgical. CONCLUSIONS: Bouveret's syndrome is one of the rare complications of gallstone. Endoscopic management can be effective at removing the impacted gallstones, which is particularly helpful for those elderly patients who have multiple medical co-morbidities, as in our first patient. Surgical management like minimal invasive surgery (robotic) can be beneficial in failed endoscopic attempt of removal of stone like in the second patient.

Afghan medical students' perceptions, and experiences of their medical education and their professional intentions: a cross-sectional study.

BACKGROUND: Numerous challenges have crippled the Afghan healthcare system on individual, organizational, and societal levels. The Afghans have acknowledged that an evidence-based perspective is paramount to enhancing medical training capacities across the country, which may, in turn, best ensure appointing highly competent authorities to address health system problems on such multiple levels. OBJECTIVES: This study assessed current Afghan senior medical students' perceptions, and experiences of their medical education and their future professional intentions. METHODS: We conducted this cross-sectional study at seven public and private Afghan medical institutes from March to April 2022. We invited 665 senior medical students through an anonymous survey using the Google survey online forms via social-media platforms, such as WhatsApp Messenger. Descriptive statistics were employed for the data analyses. RESULTS: The mean age (± SD) of the students was 23.7 (± 2.2) years and males constituted 79.9% (510) of the study sample. About 22.6% of them rated their medical training as excellent, and nearly a third of them (37%) said that it is good. Nearly half (48.7%) of the students would prefer to stay in Afghanistan. The leading motives for moving overseas were to obtain more advanced and quality education (69.9%), and a decent personal life (43.9%). Nearly two-thirds (67.4%) of them asserted that current political and armed conflicts in Afghanistan may have influenced their professional choices. CONCLUSION: This study epitomizes that the quality of medical education in Afghanistan has room for growth and development to meet the standards set on regional and global grounds.

High Prevalence of Uncontrolled Hypertension Among Afghan Hypertensive Patients: A Multicenter Cross-Sectional Study.

Background: Despite striking advances in the management of hypertension, blood pressure (BP) control remains suboptimal worldwide. Sustainable Development Goals (SDGs) call for 80% control rates by 2030, highlighting the urgency for improvements in hypertension control. Objective: We aimed to determine the prevalence of uncontrolled hypertension (≥140/90 mmHg) and assess its associated factors in Afghan hypertensive patients. Methods: We conducted this multicenter cross-sectional study at three Afghan public hospitals in Afghanistan. We recruited hypertensive patients (n=950) on antihypertensive medications (AHMs) from August to December 2022. We analyzed only complete datasets (853). We employed the 14-item Hill-Bone compliance scale to assess compliance with AHMs. We performed multivariable logistic regression analyses to determine factors associated with uncontrolled hypertension. Results: The mean age (±SD) of the patients was 47.5 (± 9.5) years and males constituted 50.5% (431) of the study sample. The prevalence of uncontrolled hypertension in this study was 77.3% (95% CI: 74.2-79.9%). Factors associated with uncontrolled hypertension and their adjusted OR (95% CI) were physical inactivity: 3.45 (1.87-6.35), current smoking: 3.04 (1.50-6.15), high salt intake: 3.57 (1.9-6.7), presence of comorbid medical disease: 2.22 (1.20-4.08), higher BMI: 3.32 (1.12-9.88), poor compliance to AHMs: 8.50 (4.62-15.6), and presence of depressive symptoms: 1.99 (1.2-3.27). Conclusion: The prevalence of uncontrolled hypertension was high in the present study. Factors associated with uncontrolled hypertension may epitomize potential targets for public/individual health interventions in Afghanistan.

Endoscopic vacuum therapy (EVT) in the management of oesophageal perforations and post-operative leaks.

INTRODUCTION: Oesophageal perforations and post-oesophagectomy anastomotic leaks are associated with high morbidity and mortality. Endoscopic vacuum therapy (EVT) is a novel treatment strategy with the potential to promote healing and ameliorate sepsis. Only two cases of its use have been reported in the UK in the management of oesophageal wall defects, representing a limited aetiological and demographic spectrum. MATERIAL AND METHODS: From May to December 2019, 7 patients aged 27-85 years underwent EVT for disparate oesophageal wall defects. Data regarding technical success and feasibility were analysed. RESULTS: Complete defect resolution was achieved in six cases (86%), requiring median of 13 days of treatment (range 6-23), and necessitating three replacement procedures (range 1-4). Significant improvement in C-reactive protein was achieved in all patients undergoing treatment (p = .015). No severe complications occurred that resulted directly from sponge placement, however two individuals (33%) developed oesophageal stricture necessitating endoscopic balloon dilatation, and one died whilst undergoing treatment. CONCLUSION: In selected patients EVT is a safe, valuable tool for the management of a spectrum of oesophageal wall defects, with the potential to reduce associated morbidity and mortality. While this work significantly expands upon the UK reported experience of EVT, we outline the requirement for a national, prospective registry of EVT use in oesophageal leaks and perforations. ABBREVIATIONS: AL: anastomotic leak; CRP: C-reactive protein; CT: computed tomography; EVT: endoscopic vacuum therapy; HES: hospital episode statistics; OGD: oesophago-gastro-duodenoscopy; SEMS: oesophageal stenting with self-expanding stents; UK: United Kingdom.

The Effect of Bariatric Surgery on Patients with HIV Infection: a Literature Review.

Obesity among human immunodeficiency virus (HIV)-infected individuals is on the rise. Bariatric procedures such as Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) alter the GI tract. Whether this alteration has any impact on the absorption of highly active antiretroviral therapy (HAART), thus affecting HIV disease markers such as CD4 cell count or viral load (VL), is not yet known. We conducted this review to look into the outcomes of bariatric surgery procedures, RYGB, SG and adjustable gastric band (AGB) and its effects on the CD4 cell counts and VL and HAART therapy. A literature search was conducted between January and April 2017, by two independent reviewers, using Pubmed and Google Scholar. The terms 'bariatric surgery and HIV', 'obesity surgery and HIV', 'gastric bypass surgery and HIV', 'sleeve gastrectomy and HIV' and 'gastric band and HIV' were used to retrieve available research. Of the 49 papers reviewed, only 12 reported the outcomes of patients with HIV undergoing bariatric surgery and were therefore included in this review. Six papers assessed patients undergoing RYGB only (N = 18), 3 papers reported on SG only (N = 18) and 3 papers reported on case mix, including 7 cases of RYGB, 4 cases of SG and 11 cases of AGB. Data is limited; however, based on the available data, bariatric surgery is safe in HIV-infected individuals and does not have any adverse impact on HIV disease progress. Additionally, there was no difference in HIV-related outcomes between SG and RYGB.

Physiological study of the anorectal reflex in patients with functional anorectal and defecation disorders.

OBJECTIVE: Fecal incontinence (FI) and constipation can arise from a variety of alterations of anorectal function. This study aimed to investigate the components of the anorecal reflex in patients with these symptoms and to determine the functional significance of various physiological parameters. METHODS: Altogether 21 healthy volunteers (controls) and 78 FI-predominant and 74 constipation-predominant patients were recruited and administered Wexner incontinence and constipation questionnaires. All participants underwent standardized anorectal physiology assessments. RESULTS: Patients with passive FI had lower resting sphincter pressures than controls (38 cmH2 O vs 87 cmH2 O, P < 0.05), while those with urge FI had lower squeeze pressures than controls (37 cmH2 O vs 119 cmH2 O, P < 0.05). Patients with urge FI had lower maximal tolerable volumes (100 mL vs 166 mL, P < 0.05). Patients with slow-transit constipation had elevated rectal electrosensitivity thresholds compared with controls (31.4 mA vs 20.2 mA, P < 0.05), and rectal mucosal blood flow than patients with evacuation difficulty and controls (107 vs 162 flux units (FU) [evacuation difficulty] vs 169 FU [controls], P < 0.05). Only patients with passive FI were associated with reflex abnormalities (prolonged recovery phase (1.2 ms vs 0.5 ms, P < 0.05) and total duration of reflex (6.3 ms vs 4.3 ms, P < 0.05). CONCLUSIONS: Anorectal motor, sensory and reflex abnormalities are seen in distinct patterns in patients with FI and constipation. This would suggest distinct physiological differences that may predict the potential for different neuromodulation treatment and behavioral modalities in these conditions.

Acrometastasis following colorectal cancer: A case report and review of literature.

INTRODUCTION: Colorectal cancer commonly metastasises to the liver, peritoneum and lungs. Bony metastases are uncommon in colorectal cancer and in particular metastases to the hands or feet (acrometastasis) are an extremely rare occurrence. CASE PRESENTATION: A 65-year-old male with a colonic malignancy underwent elective anterior resection. Intra-operatively he was found to have a pelvic collection necessitating an end colostomy. Histology confirmed complete Dukes B tumour excision with no evidence of lymph node metastases. The patient underwent chemo-radiotherapy but was unsuitable for reversal of Hartmann's due to elevated CEA levels and asymmetrical thickening of the rectal stump with a solitary lung nodule identified at a one-year surveillance CT. The lung nodule was resected revealing metastatic adenocarcinoma and biopsies from the rectal stump showed chronic inflammatory changes. The patient was offered further chemotherapy. However, six years after his original surgery the patient presented with an acutely painful left foot with radiographic appearances of an infiltrative sclerotic and lucent lesion confirmed as a calcaneal acrometastasis on Magnetic Resonance Imaging (MRI). DISCUSSION: Diagnosis of acrometastasis is challenging and generally constitutes a wider metastatic process with poor prognosis. Patients are often asymptomatic or present with symptoms mimicking benign lesions such as arthritis, infection or ligamentous sprains of the hands or feet. Therefore, there should be a high index of suspicion and prompt radiological investigation is warranted in order to exclude disease recurrence. CONCLUSION: Although acrometastasis may indicate a poor prognosis, timely diagnosis and intervention may facilitate improvement of long-term survival and symptomatic management.

Mesenteric Meckel's diverticulum: an unusual cause of small bowel intussusception.

Meckel's diverticulum (MD) is the commonest congenital anomaly of the small intestine, affecting 1-4% of the population. Cardinal features emphasise an antimesenteric location two feet proximal to the ileocaecal valve, with a separate mesenteric blood supply and involvement of all layers of the small intestine. However, reports of MD arising from the mesenteric border of the small intestine are rare in the surgical literature. This report examines the case of a 45-year-old woman presenting with a 6-month history of episodic central abdominal pain and microcytic anaemia who underwent an elective diagnostic laparoscopy as initial CT findings were inconclusive. Intraoperatively, she was found to have small bowel intussusception approximately 40 cm proximal to the ileocaecal valve. Macroscopic examination of the resected small bowel segment revealed a mesenteric outpouching that was confirmed as mesenteric MD on histopathological analysis. Postoperatively, the patient recovered with no surgical complications and full symptom resolution.

Evaluating the quality of internet information for bariatric surgery.

BACKGROUND: The internet is frequently used by patients seeking information on bariatric surgery. This study aims to evaluate the quality of this information. METHOD: The terms 'weight loss'; 'weight loss surgery', 'obesity surgery' and 'bariatric surgery' were searched for in three common search engines. The quality of websites retrieved was assessed with the DISCERN Plus tool. RESULTS: Thirty websites were assessed. The range of scores was 23-66 out of 80. On average, the quality of websites was of 'poor' to 'fair' quality. CONCLUSION: The quality of information is highly variable, and on average of poor, or fair quality. Healthcare professionals should be aware of this when discussing bariatric surgery with patients who have sought information on the internet.

De Garengeot's hernia: our experience of three cases and literature review.

Groin hernia is a common surgical presentation and nearly half of the femoral hernias present acutely with strangulation. The hernia sac usually contains omentum or small bowel. Rarely, the appendix can herniate into the femoral canal. De Garengeot's hernia is the term used to describe the presence of appendicitis in the femoral hernia. Hernia explorations are performed by surgical trainees and encountering a De Garengeot's hernia can be challenging to manage. We report our experience of three cases of this rare entity and a literature review to improve our understanding for optimum management.
