Bursting Heart Syndrome: A Rare Case Of Aortocaval Fistula Repair.

In this case report we will discuss the case of a 47-year-old woman who presented with abdominal pain, nausea, oliguria and right heart failure. A Computed Tomography (CT) aortogram revealed a fistulous abdominal aortic aneurysm. The objective of this study is to discuss the haemodynamic changes regarding aortocaval fistula and consider various management options. A literature search was undertaken on PubMed using appropriate search terms. Case series and reviews reporting presentation, diagnosis and operative management of aortocaval fistula were selected and discussed. We reached a conclusion that early identification improves surgical planning and reduces mortality. Major abdominal arteriovenous fistula repair appears to be a safer and more successful therapy with positive short and midterm outcomes. Aortocaval fistula care requires a more extensive patient series, so even better conclusions can be drawn.

Forearm Basilic Vein Transposition: A Single-Centre Experience.

INTRODUCTION: Forearm basilic vein transposition (FBVT) is a viable alternative for arteriovenous grafts (AVGs) and can be used as secondary vascular access as well, as it allows for the use of veins that are remote from the arterial source of inflow. FBVT involves two main steps: first, the basilic vein is dissected from its original location; and second, the basilic vein is transposed to a subcutaneous tunnel on the volar aspect of the forearm and anastomosed to a suitable artery, usually the radial or ulnar artery. OBJECTIVE: This paper aims to present a series of FBVT cases performed at our hospital and present it as a viable option for secondary vascular access. We also aim to review the available literature relating to FBVT fistula in terms of surgical technique, patency rates, maturation time, and one-year outcome, and to establish a comparison with our clinical experience. MATERIALS AND METHODS: This is a retrospective descriptive case series. The data were collected from online medical records, and patients were contacted by telephone to make a follow-up visit. For a review of the literature, a search was done on PubMed for articles containing the following keywords in either the title or the abstract: basilic, transposition, fistula, and forearm. Similarly, a search was done on Google Scholar for articles with the following words in the title: basilic, transposition, and forearm. The data are expressed as mean and standard deviation. Statistical analysis was done using SPSS 26.0 software (IBM Corp., Armonk, NY). CONCLUSION: The primary patency rate of FBVT in our study makes it a suitable solution to opt for before moving to AVGs. FBVT should be considered before moving more proximally in patients with inadequate forearm cephalic veins.

Surgical Site Infection After Stoma Reversal: A Comparison Between Linear and Purse-String Closure.

INTRODUCTION: Intestinal stomas are utilized for both benign and malignant conditions of the intestine to mitigate the risk of anastomotic leakage and re-exploration. However, stomas are associated with various complications, such as stoma necrosis, peri-stomal irritation, parastomal hernia, bleeding, bowel obstruction, and electrolyte abnormalities. Surgical site infection (SSI) is a significant source of morbidity following stoma reversal, leading to increased patient morbidity. The conventional method of stoma reversal involves closing the skin with non-absorbable sutures in a linear fashion, which is known as linear skin closure (LSC). Recently, a new method of skin closure using purse-string approximation (PSA) has been advocated, which allows healing by secondary intention. The rationale for this study is to compare the SSI associated with LSC and PSA after stoma reversal. OBJECTIVE: This study aims to compare the frequency of SSI between LSC and PSA in stoma reversal. MATERIALS AND METHODS: The study was conducted at the Department of General Surgery, Shifa International Hospitals Ltd. (SIH), Islamabad, Pakistan. The study is a randomized controlled clinical trial carried out between the 14th of March 2021 and the 22nd of November 2022. The sampling technique was non-probability consecutive random sampling. The sample size was calculated using the WHO sample size calculator by using the hypothesis test for two population proportions. The minimum sample size in each group was 40 patients. The total sample size was 80 patients. RESULTS: The overall frequency of SSI in all the patients was 18/80 (22.5%). The frequency of SSI in Group 1 (LSC) was 6/40 (15.0%), and in Group 2 (PSA), it was 12/40 (30.0%). The frequency of SSI in Group 2 (PSA) was twice as high as in Group 1 (LSC); however, the p-value was calculated to be 0.108. Therefore, this difference was statistically insignificant. CONCLUSIONS: While PSA has exhibited promise in reducing SSI rates and enhancing aesthetic outcomes and patient satisfaction, there is still enough data favoring LSC. Moreover, insufficient data is available for our population to make a definitive statement. Consequently, further research on this topic is warranted, preferably involving larger sample sizes and multicenter randomized controlled trials, to establish which technique is superior in SSI reduction.

The Efficacy of Conservative Management in Uncomplicated Acute Appendicitis - A Single-Center Retrospective Study.

Background Acute appendicitis remains the most common cause of lower abdominal pain leading to emergency visits. Even though the standard treatment of acute appendicitis remains appendectomy, in recent times, multiple randomized control trials and meta-analyses have deduced conservative treatment as a successful alternative treatment. During the coronavirus disease (COVID) pandemic, with a shortage of staff and resources, treatment with conservative management of uncomplicated acute appendicitis became very beneficial under certain circumstances and conditions. This study aimed to assess whether it is effective to manage patients with uncomplicated acute appendicitis with antibiotic therapy. Methodology This was a single hospital based retrospective, cross-sectional study from Jan 2015 to May 2020. Patients with clinical and radiological features of uncomplicated acute appendicitis with Alvarado's score >6 were included in the study. Patients were kept on antibiotics, intravenous fluids, and analgesia as part of a conservative regime. Those who failed to respond to conservative therapy were managed surgically. The follow-up period was six months. Results One hundred eighty-two cases of uncomplicated acute appendicitis were included and managed conservatively, of which 52.2% were males while 47.8% were females. The median age of the patients was 26 years. Conservative treatment was successful in 26.2% of the patients, with a recurrence of 5.5% in the six-month follow-up period. The mean number of days of hospital stay was three days in patients treated with conservative or surgical treatment. Conclusion Conservative management is gaining popularity, and many centers are inclined towards non-operative management; however, appendectomy remains the gold standard treatment for appendicitis.

Pre-operative Intraperitoneal Drainage Under Local Anesthesia: A Promising Resuscitation Tool in Peritonitis Secondary to Hollow Viscus Perforation During the Corona Pandemic.

Introduction To study the role of intraperitoneal drainage in the resuscitation of patients with perforation peritonitis during the corona pandemic. Materials and methods This retrospective study was conducted in the general surgery department of Nishtar Medical University/Hospital Multan from April 2020 to September 2020. Patients of peritonitis who presented with bilateral pulmonary crepitations, SpO2 less than 92%, PaO2 less than 60 mmHg on arterial blood gas (ABG), and chest x-ray (CXR) finding of bilateral infiltrates are included. Due to high suspicion of associated coronavirus infection such patients needed polymerase chain reaction (PCR) for virus detection and special measures were required for resuscitation before any definitive treatment. A delay of six to eight hours is usually encountered while ensuring proper safety measures and dedicated operation theaters. Initial resuscitation started with intravenous fluids and broad-spectrum antibiotics were given to all patients. Twenty-seven patients were resuscitated with preoperative intraperitoneal drainage while waiting for PCR and 13 patients were resuscitated without drainage. Data analysis was carried out using the statistical package for the social sciences (SPSS) version 19 software. The mean was calculated for age while frequency and percentages were calculated for gender, comorbidities, and causes of delay. The mortality was compared using the chi-square test. Results The mean age of patients was 43.73 ± 16.04 years. The common cause of peritonitis were perforations due to duodenal ulcer, typhoid, tuberculous (TB), and biliary origin. The variables that led to suspicion of coronavirus were SpO2 < 92%, PaO2 <60mmHg and bilateral infiltrates on chest x-ray. PCR for coronavirus was positive in nine patients. Mortality was 29.6% in those resuscitated with intraperitoneal drainage before the definitive procedure and 54% in those not resuscitated with intraperitoneal drainage. Conclusions The surge of coronavirus infection has put the healthcare staff at great risk. This has led to strict protocols and precautionary measures in the management of patients with perforation peritonitis with suspected corona infection. The local guidelines for the management of patients with acute abdomen should include aggressive measures right from the start during the corona pandemic. Intraperitoneal drainage, early in the management of perforation peritonitis decreases morbidity and mortality in suspected corona infected patients.
