Comparison of laparoscopic port site skin closure techniques (CLOSA): transcutaneous suturing versus subcuticular sutures versus adhesive strips: a prospective single-blinded randomized control trial.

BACKGROUND: Cosmesis is an essential aspect of laparoscopic surgery. Various methods of skin closure techniques have been described. We conducted a study to evaluate the cosmesis and patient satisfaction with the scars three months after laparoscopic surgery using transcutaneous suture (TS) vs. adhesive strips (AS) and subcuticular suturing (SS). METHODS: A randomized, controlled, prospective study was conducted at AIIMS, Bhubaneswar. The included patients were randomly assigned among the three arms. The time for skin closure was measured. Wounds were assessed till discharge, at 14 days, one month, and three months. Cosmesis was measured by the Hollander Wound evaluation scale (HWES) for each incision separately, and patient satisfaction by a 10- point Visual analog scale (VAS). RESULTS: One hundred six patients were assessed for eligibility, and 90 patients were randomized. Three-month follow-up data was obtained from 83 patients (92.22%). Baseline characteristics were similar among the groups. Cosmetic outcome was assessed in 312 incisions across 83 patients, and 206 (66.03%) incisions had an HWE Score of 0, but there was no significant difference (p = 0.86). Patient satisfaction was highest in the TS group (TS = 1.29, SS = 1.79, AS = 2.04, p = 0.03). Time for skin closure was the least in the AS arm (41.4 secs, p = 0.00). Skin dehiscence was significantly more in the AS arm. Four (4.44%) patients had port site infections. CONCLUSION: This study demonstrates that skin closure by transcutaneous, subcuticular, or adhesive strip methods had comparable cosmetic outcomes at three months. However, the transcutaneous closure method showed better patient satisfaction and minimal post-operative complications.

On-demand (SOS) analgesia through Transversus Abdominis Plane (TAP) catheter route for post-operative pain relief in Emergency Laparotomies-a non-randomised interventional study (STAPLE trial).

INTRODUCTION: This study aimed to compare the efficacy and safety of on-demand bupivacaine infusion via transversus abdominis plane (TAP) catheter in emergency laparotomy patients. METHODS: A non-randomised interventional study was conducted on patients undergoing emergency midline laparotomy. The intervention group received an on-demand infusion of 10 ml 0.5% bupivacaine through TAP catheters, whilst the control group received standard analgesic care. The primary outcome was the amount of rescue analgesic consumption. Secondary outcomes included the post-operative, measured by visual analogue scores (VAS), side effects, time to first flatus, post-operative nausea and vomiting, and pulmonary complications. RESULTS: One-hundred-twenty patients (58 in the TAP-SOS group, 62 in the control group) were included in the final analysis. The TAP-SOS group showed significantly reduced rescue analgesic requirement by 91% (p < 0.001) and lower VAS scores at 3, 6, 12, and 24 h (adjusted p < 0.00). Time to out-of-bed mobilisation was significantly shorter in the TAP-SOS group by 12.47 h (p < 0.001), and post-operative pulmonary complications were lower by 75% (p < 0.05). There were no significant differences in bowel recovery, catheter-related complications, or post-operative morbidity. No incidences of catheter-site infection were reported on follow-up; however, the catheter tip-culture was positive in 3 (5.17%) patients. CONCLUSION: On-demand bupivacaine infusion through a TAP catheter effectively reduced post-operative pain and opioid requirements in emergency laparotomy patients without complications. If an epidural is not an option, the TAP-SOS approach can be a helpful adjunct in implementing the ERAS protocol in an emergency since it allows for early ambulation and better pain management.

Comparison of surgical site infection (SSI) between negative pressure wound therapy (NPWT) assisted delayed primary closure and conventional delayed primary closure in grossly contaminated emergency abdominal surgeries: a randomized controlled trial.

PURPOSE: NPWT has been tried in many surgical fields, including colorectal, thoracic, vascular, and non-healing wounds, for the prevention of SSI. However, its efficacy in the prevention of SSI-grade IV closed abdominal wounds is yet to be explored. METHODS: All patients with grade IV abdominal wounds were included in the study. They were randomized into the conventional arm and the VAC arm after confirming the diagnosis intra-operatively. The sheath was closed, and the skin was laid open in the postoperative period. In the VAC arm, the NPWT dressing was applied on postoperative day (POD)-1 and removed on POD-5. In the conventional arm, only regular dressing was done postoperatively. The skin was closed with a delayed primary intention on POD-5 in both arms. The sutures were removed after 7 to 10 days of skin closure. RESULTS: The rate of SSI (10% in the VAC arm vs. 37.5% in the conventional arm, p-value = 0.004) was significantly lower in the VAC arm, as were the rates of seroma formation (2.4% in the VAC arm vs. 20% in the conventional arm, p = 0.014) and wound dehiscence (7.3% vs. 30%, p = 0.011). The conventional arm had a significant delay in skin closure beyond POD5 due to an increased rate of SSI, which also led to a prolonged hospital stay (5 days in the VAC arm vs. 6.5 days in the conventional arm, p-value = 0.005). CONCLUSION: The VAC dressing can be used routinely in grade IV closed abdominal wounds to reduce the risk of SSI and wound dehiscence.

Ultrasound-guided selective peripheral nerve block compared with the sub-dissociative dose of ketamine for analgesia in patients with extremity injuries.

STUDY OBJECTIVE: To compare the analgesic efficacy of ultrasound-guided selective peripheral nerve block (PNB) and sub-dissociative dose ketamine (SDK) for management of acute pain in patients with extremity injuries presenting to the emergency department (ED). METHODS: This prospective, open-label randomized clinical trial was conducted in the ED of a tertiary care Institute. The patients were provided with either ultrasound-guided selective PNB or SDK. The primary outcome was a reduction in pain in numerical rating scale (NRS) by at least 3 points without rescue analgesia. The secondary outcomes were the need for rescue analgesia, adverse events, and patient satisfaction on either arm. RESULTS: A total of 111 patients with isolated traumatic extremity injuries were included in the final analysis. The NRS score was significantly lower in the PNB group compared to the SDK group at 30, 60,120, 180-, and 240-min post-intervention [group ∼ time interaction, F (5, 647) = 21.53, p ≤ 0.001]. All the patients in the PNB group exhibited primary outcome (NRS ≥3 reductions) at 30 min post-intervention compared with 36 (65%) in the SDK group [-1.02(-1.422,0.622)]. Rescue analgesia was required in 10 (18%) patients in the SDK group compared to none in the PNB group [0.663(0.277,1.050)]. The decrease in NRS score from baseline at 30 min was significantly higher in PNB groups compared to the SDK group [-2.166(-2.640, -1.692)]. The most common side effect reported in the SDK group was dizziness 35(64%), followed by nausea 15(27%). None of the patients in the PNB group reported any complications. Patient satisfaction was higher in the PNB group than SDK group. CONCLUSION: The study provides evidence that ultrasound-guided PNB is superior to SDK in terms of its analgesic efficacy in the management of acute pain due to extremity injuries and is associated with higher patient satisfaction. The need for rescue analgesia was significantly less in the PNB group. SDK was associated with a high incidence of dizziness and nausea.

Impact of personal protective equipment on patient safety and health care workers.

Background: The study aims to assess the effect of personal protective equipment (PPE) on the physical and psychological well-being of health care workers (HCWs) and its impact on patient safety. Methods: After ethical approval, a 14-point questionnaire was circulated offline and online among the HCWs of ours institute, who were involved in performing invasive procedures while wearing a PPE. The responses were analysed using the SPSS software version 26. Results: Of 198 responses, the mean duration of PPE use was 4.6 ± 1.52 h. Seventy percent of respondents suggested <4 h of continuous use of PPE. Seventy-seven percent found difficulties during the procedures while wearing PPE and agreed to errors while performing a procedure. Poor visibility (95.5%), fogging (84.9%), communication difficulty (75.3%), sweating (74.2%), posture-related discomfort (56.1%) and poor concentration (51%) were major causes. Anxiety (39.9%) and fear of spreading an infection to the family (42.9%) were major psychological effects. Eighty percent of HCWs raised concern over the quality of PPE, N95 mask and eye protector. The HCWs felt the need to improve the quality of PPEs, use extra padding around the ears, sealing the N95 mask with adhesive tape, besides using sign language for communication for more safety. Fifty percent graded the procedure-related difficulty level >6 on a Likert scale of 1-10. Conclusion: PPE-related discomfort is common among the HCWs and could contribute to errors during an invasive procedure. Efforts to alleviate the physical and psychological well-being of the HCWs will be essential for reducing procedural error while wearing a PPE.

Cytology of angiofibroma of soft tissue of the inguinal region.

Angiofibroma of the soft tissue is a recently described benign fibroblastic/myofibroblastic tumour. This report describes the cytology of an angiofibroma of soft tissue occurring in a 30-year-old lady which showed bland spindle cells, occasional polygonal cells with nuclear grooving, prominent vessels, frayed stroma around the blood vessels, and scattered lymphocyte-rich inflammatory cells in the background.

Incidence and clinical outcomes of bleeding complications and acute limb ischemia in STEMI and cardiogenic shock.

BACKGROUND: Bleeding complications and acute limb ischemia (ALI) are devastating vascular complications in patients with ST-segment elevation myocardial infarction (STEMI). Cardiogenic shock (CS) can further increase this risk due to multiorgan failure. In the contemporary era, percutaneous mechanical circulatory support is commonly used for management of CS. We hypothesized that vascular complications may be an important determinant of clinical outcomes for CS due to STEMI (CS-STEMI). OBJECTIVE: We evaluated 10-year national trends, resource utilization and outcomes of bleeding complications, and ALI in CS-STEMI. METHODS: We performed a retrospective cohort study of CS-STEMI patients from a large U.S. national database (National Inpatient Sample) between 2005 and 2014. Events were then divided into four different groups: no MCS, with intra-aortic balloon pump, percutaneous ventricular assist device includes Impella or Tandem Heart or extracorporeal membrane oxygenation. RESULTS: Bleeding complications and ALI were observed in 31,389 (18.2%) and 1,628 (0.9%) out of 172,491 admissions with CS-STEMI, respectively. Between 2005 and 2014, overall trends increased for ALI; however, the number of bleeding events decreased. ALI was associated with increased in-hospital mortality in comparison to those without any ALI. However, bleeding complications were not associated with increased in-hospital mortality. Compared to patients without complications, both bleeding and ALI were associated with increased length of stay (LOS) and hospitalization costs. CONCLUSIONS: Bleeding and ALI are common complications associated with CS-STEMI in the contemporary era. Both complications are associated with increased hospital costs and LOS. These findings highlight the need to develop algorithms focused on vascular safety in CS-STEMI.

Incidence and clinical outcomes of stroke in ST-elevation myocardial infarction and cardiogenic shock.

OBJECTIVE: The authors sought to evaluate 10-year national trends, incidence and clinical outcomes of stroke in CS-STEMI. BACKGROUND: Stroke is a devastating complication among patients with ST-elevation myocardial infarction (STEMI). Concomitant cardiogenic shock (CS) may further increase the risk of stroke. Use of percutaneous mechanical circulatory support (pMCS) devices may further increase stroke risk in CS-STEMI. No studies have evaluated the risk of stroke in contemporary CS-STEMI. METHODS: We performed a retrospective cohort study of CS-STEMI patients from a large U.S. national database between 2005 and 2014. Previously validated codes for stroke were used to identify events of ischemic or hemorrhagic stroke. They were then divided into different groups: without MCS, with intra-aortic balloon pump, percutaneous ventricular assist device (PVAD, includes Impella or TandemHeart devices), or extracorporeal membrane oxygenation. RESULTS: In 172,491 admissions, stroke was noted in 5,613 (3.2%). Between 2005 and 2014, we observed an increase in the events of overall stroke from 3.1% in 2005 to 5.0% in 2014 (p for the trend <.001). The number of ischemic stroke events (2.4%) was higher than hemorrhagic stroke (0.1%) during the study period. Presence of stroke was associated with higher in-hospital mortality (40.6 vs. 29.8%, 95% CI adjusted odds ratio: 1.57, 1.44-1.67; p < .0001 among stroke vs. without stroke). CONCLUSIONS: The incidence of stroke events in CS-STEMI patients increased between 2005 and 2014, and is associated with higher in-hospital mortality, length of stay, and cost of hospitalization. The incidence of both hemorrhagic and ischemic stroke was higher with pMCS device use. Stroke prevention is a priority for CS-STEMI patients.

Trends in the Incidence of In-Hospital Mortality, Cardiogenic Shock, and Utilization of Mechanical Circulatory Support Devices in Myocarditis (Analysis of National Inpatient Sample Data, 2005-2014).

BACKGROUND: Myocarditis may be associated with hemodynamic instability and portends a poor prognosis when associated with cardiogenic shock (CS). There are limited data available on the incidence of in-hospital mortality, CS, and utilization of mechanical circulatory support (MCS) devices in these patients. METHODS: We queried the 2005-2014 National Inpatient Sample databases to identify all patients aged >18 years with myocarditis in the United States. RESULTS: The number of reported cases of myocarditis per 1 million gradually increased from 95 in 2005 to 144 in 2014 (Pfor trend <.01). The trend and incidence of endomyocardial biopsy remained the same despite the increase in clinical diagnosis. Overall, in-hospital mortality was 4.43% of total admissions without a change in overall trend over the study period. We also observed a significant increase in the incidence of CS from 6.94% in 2005 to 11.99% in 2014 (Pfor trend <.01). There was a parallel increase in the utilization of advanced MCS devices during the same time period such as extracorporeal membrane oxygenation or percutaneous cardiopulmonary support (0.32% in 2005 to 2.1% in 2014; P< .01) and percutaneous ventricular assist devices such as Impella/tandem heart (0.176% in 2005 to 1.75% in 2014; P< .01). CONCLUSION: Although the incidence of myocarditis has increased in the last decade, the in-hospital mortality has remained the same despite increases in the incidence of CS, possibly reflecting the benefits of increased usage of advanced MCS devices. We noted that increasing age, presence of multiple comorbidities and CS were associated with an increase in in-patient mortality.

Aspirin Resistance: Cardiovascular Risk Game Changer.

BACKGROUND: Aspirin (ASA) is the most used medication on the globe. ASA is a primary pillar of the secondary prevention of cardiovascular atherothromboembolic events. However, a fraction of the population does not respond to ASA as expected in a unique phenomenon called ASA resistance. Multiple mechanisms were described and studied in the literature to explain this phenomenon. AREA OF UNCERTAINTY: ASA resistance is an interesting phenomenon that is worth studying and reviewing. Mechanisms behind this resistance are various and although the rarity of some, it is crucial for the modern health provider to be aware of such phenomenon and its possible explanations to provide more efficient preventive cardiology practice. Our study aimed to review and conclude the evidence behind ASA resistance and its implication on the cardiovascular health. DATA SOURCES: We searched databases like PubMed, EMBASE, Ovid by midline, and Google Scholar for published articles and abstracts. RESULTS: Our systemic search revealed more than 100 articles in relation to ASA resistance. We selected 40 articles, which were relevant for this review. Various mechanisms were described in the literature, with few of them very well documented and understood. Main mechanisms include medication nonadherence, interaction with proton pump inhibitors, esterase-mediated ASA inactivation, post-coronary artery bypass grafting (CABG) MRP-4-mediated ASA consumption, cyclooxygenase-1 (COX-1) polymorphisms, high platelet turnover-associated regeneration of platelet COX-1, and the documented platelet ability of de novo COX-1 synthesis in response to thrombin and fibrinogen. CONCLUSION: Multiple mechanisms of ASA resistance were described in the literature. Awareness of such interaction is important for medical practitioners. Bottom line, further studies and reviews are needed to further study this phenomenon and its implication on the cardiovascular health and hence reaching a valid evidence-based conclusion that might change the practice and improve the patient preventive health care.

Opioid-free anesthesia for breast cancer surgery: A comparison of ultrasound guided paravertebral and pectoral nerve blocks. A randomized controlled trial.

BACKGROUND AND AIMS: Pectoral block (PECS)-based anesthesia without opioids decreases analgesic requirement, pain scores and post-operative nausea vomiting (PONV) compared to conventional opioid-based general anesthesia in patients undergoing modified radical mastectomy and axillary dissection (MRM-AD). We compared PECS versus Paravertebral Block (PVB) in providing an opioid free, nerve block-based regimen. Outcomes of interest were post-operative analgesic requirement, duration of analgesia, PONV and patient and surgeon satisfaction. MATERIAL AND METHODS: This randomised controlled study involved 58 adult ASA I-III patients posted for MRM-AD. After randomization patients were induced with propofol and maintained on spontaneous ventilation with isoflurane (0.8-1.0 MAC) through i-gel. Ultrasound-guided PECS or PV blocks (30 ml of 0.1% lignocaine + 0.25% bupivacaine + 1 µg/kg dexmedetomidine) were administered. Post-operative pain scores, non-opioid analgesic requirement over 24 hours, PONV, satisfaction of surgeon and patient were measured. RESULTS: Between the two groups, there was no difference in demographics, ASA status, location and volume of breast tumour excised or the duration of surgery. The time from block to incision was significantly longer in the PV group (P = 0.01). There was no difference between the two groups in terms of intra and post-operative parameters, and the median VAS scores for pain at rest or during shoulder abduction were similarly low in both the groups. CONCLUSION: Both blocks result in equally prolonged analgesia and preclude requirement of opioid analgesics intra and post-operatively. PECS block is associated with lesser time to allow incision. Complications are low in both the groups. Routine use of these blocks to avoid opioids may be studied further.

Giant dedifferentiated liposarcoma of small bowel mesentery: a case report.

BACKGROUND: Dedifferentiated liposarcoma is an uncommon variant of liposarcoma, with poor prognosis and higher preponderance to local recurrence. Only nine cases of dedifferentiated liposarcoma of small bowel mesentery have been reported till now. This is a case of giant dedifferentiated liposarcoma of the small bowel mesentery, weighing nearly 9 kg (19.8 lbs), with synchronous lesions in the extraperitoneal space, which is the first such case to be reported. CASE PRESENTATION: We report a case of a 62-year-old man, who presented with a huge abdominal mass occupying nearly the entire abdomen. A contrast enhanced computed tomography of abdomen and pelvis revealed a large, poorly enhancing, heterogeneous, lobulated mass of size 27 × 16 cm, displacing the bowel loops peripherally. At laparotomy, a large mass arising from the small bowel mesentery was found. In addition, many other smaller synchronous lesions were studded in the entire small bowel mesentery and a couple more in the extraperitoneal space. A palliative excision of the giant mass along with the adjacent small bowel was done. The other smaller swellings were not causing any mass effect and were left behind as they were numerous, virtually ruling out any possibility of a curative excision. The histopathological examination suggested the diagnosis of dedifferentiated liposarcoma. On immunohistochemistry, S-100 was positive in the well-differentiated sarcomatous areas. The CD 117 and SMA were strongly negative ruling out the possibility of a gastrointestinal stromal tumour. The CD 34 however was positive in the tumour cells. CONCLUSIONS: Dedifferentiated liposarcoma of the small bowel mesentery is rare. Involvement of nearly whole of the small bowel mesentery in the disease process virtually rules out the possibility of a curative resection, the mainstay of management. This report would add to the knowledge of this rare disease and the possible therapeutic problem that may be encountered in case of multifocal disease.

Is laparoscopic cholecystectomy effective in relieving dyspepsia in patients of cholelithiasis? A prospective study.

Background: Laparoscopic cholecystectomy (LC) is routinely done for symptomatic gallstone disease; however, its role in relieving dyspeptic symptoms in cholelithiasis is controversial. Aim: The study was designed to assess the role of laparoscopic cholecystectomy in relieving dyspeptic symptoms in patients having cholelithiasis with only dyspeptic symptoms. Methods: Patients with cholelithiasis having only dyspeptic symptoms not attributable to other causes (like Helicobacter pylori) were subjected to laparoscopic cholecystectomy. Dyspepsia scores (Dyspepsia Severity Assessment Score-DSAS and Gastrointestinal Quality of Life Index- GIQLI) were measured before and after surgery and analyzed using Greenhouse-Geisser, McNemar's and ANOVA tests. Results: 27 patients (M:F=1:26, mean age=40.48±10.60 years) having dyspepsia with asymptomatic gallstones were included in the study. There was significant improvement in DSAS (20.11±4.36 vs 28.63±3.42; p<0.001) and GIQLI(106.11±5.77 vs 122.56±7.95; p<0.001) after 2 months of LC. All symptoms improved individually; relief in early satiety and vomiting was the maximum (outcome benefit ratios=0.954, p=0.007 and 0.937, p=0.005 respectively). Multiple gallstones caused more dyspepsia than single (p=0.005). There was no significant difference between H. pylori positive and negative groups in terms of improvement of DSAS and GIQLI scores after LC (p=0.897 and p=0.375 respectively; however dyspepsia was seen to improve significantly within both groups). Conclusion: Dyspepsia may be a symptom of gallstone disease, and these patients can benefit from LC especially when early satiety and vomiting are the main symptoms. A larger sample size may offer more insight.

Totally extraperitoneal repair under general anesthesia versus Lichtenstein repair under local anesthesia for unilateral inguinal hernia: a prospective randomized controlled trial.

BACKGROUND: Lichtenstein repair (preferably under local anesthesia) or totally extraperitoneal repair (TEP) are both good options for treating uncomplicated unilateral inguinal hernia. We performed a prospective randomized trial to compare the outcome of TEP repair under general anesthesia versus open Lichtenstein inguinal hernioplasty under local anesthesia. METHODS: Adult men with primary unilateral inguinal hernia without any history of lower abdominal surgery were assessed for inclusion in the study. Of the 194 patients assessed for eligibility for recruitment in the trial, 72 were recruited in the trial and randomized into two groups of 36 patients each. A per-protocol analysis was performed. Patients were followed for a period of 3 months. Pain was assessed by a visual analog scale, and quality of life was assessed by the SF-36 Health Survey Questionnaire, version 2. RESULTS: A total of 59 patients were analyzed at the end of the study, 30 in the Lichtenstein group and 29 in the TEP group. The operating time (75.93 ± 13.68 vs. 64.77 ± 12.66 min, p = 0.002) and total operating room time (102.66 ± 15.676 vs. 72.64 ± 12.25 min, p < 0.001) were significantly longer in the TEP group. Postoperative pain scores in the TEP group were lower than the scores in Lichtenstein group, but the difference was not statistically significant. There was significantly more use of analgesics and higher C-reactive protein levels in the Lichtenstein group. Quality of life and patient satisfaction were similar in both groups. CONCLUSIONS: Lichtenstein repair under local anesthesia is as good as TEP under general anesthesia. The shorter operating room time, smaller mesh size, and lower cost of local anesthetic drugs all contribute to make Lichtenstein repair the better choice for repair of uncomplicated unilateral inguinal hernia, especially in developing nations with scarce resources.

A case of right upper abdominal pain misdiagnosed on computerized tomography.

Right upper abdominal pain is a common symptom in patients presenting to surgery emergency. Most of these cases can be diagnosed accurately on clinical evaluation or imaging. We report an unusual case of right upper abdominal pain, which could not be diagnosed correctly pre-operatively despite using various imaging modalities.

An Unusual Etiology of Severe Right Heart Failure Deserving of Wider Recognition.

A previously healthy 31-year-old man presented with worsening shortness of breath and a petechial rash. Echocardiography showed severe right-sided heart failure with midsystolic notching of the antegrade right ventricular outflow Doppler envelope suggesting pulmonary hypertension. An extensive work-up revealed scurvy, with a dramatic resolution of symptoms shortly after vitamin C supplementation.
