Efficacy of Unilateral External Oblique Intercostal Fascial Plane Block Versus Subcostal TAP Block in Laparoscopic Cholecystectomy: Randomized, Prospective Study.

This study aimed to evaluate the effectiveness of unilateral external oblique intercostal nerve block (EOIB) in laparoscopic cholecystectomy surgery. After ethics committee approval, ASA I-II patients aged 18-70 who would undergo laparoscopic cholecystectomy surgery were included in the study. The patients were divided into two groups, external oblique intercostal nerve block (Group EOIB) and oblique subcostal transversus abdominis plane block (Group OSTAP). After surgery, EOIB or OSTAP block was administered with 20mL of .25% bupivacaine then routine analgesia protocol was applied with iv paracetamol, and tramadol. Visual analog scale (VAS) scores and patient-controlled analgesia (PCA) consumption were monitored 24 hours after the operation. It was administered 25mg pethidine as a rescue analgesic to patients with VAS ≥4. Thirty six patients for Group EOIB and thirty four patients for Group OSTAP were included in the study. Lower VAS scores were observed in all groups. When PCA consumption, side effects, rescue analgesia consumption, and patient satisfaction were evaluated, there was no statistically significant difference between the groups (P > .05). It was observed that EOIB showed similar analgesic activity to the OSTAP block. EOIB may also be a part of postoperative multimodal analgesia by reducing postoperative opioid consumption in LC.

Haemodynamic responses to intubation, extubation and post‐operative analgesia after intravenous lignocaine in laparoscopic cholecystectomy surgeries: a randomized control study

ABSTRACT:
 Objectives: To evaluate the effect of intravenous lignocaine on haemodynamic responses to intubation, extubation and post‐operative analgesia in laparoscopic cholecystectomy surgeries.
 Methods: This prospective, randomized, double blinded study was conducted in patients for elective laparoscopic cholecystectomy surgery in tertiary care hospital of Tamil Nadu. Group A (n=60) received 0.9% normal saline for perioperative intravenous infusion and Group B (n=60) received preservative free lignocaine 2% (20mg/ml) as intravenous infusion Hemodynamic responses were recorded to intubation, extubation and post‐operative analgesia in both groups. VAS scores and pain free period were also compared.
 Results: Pulse rate (PR) and mean arterial pressure (MAP) were significantly increased in both the groups during laryngoscopy and intubation, though the rise of both in lignocaine group was significantly less than normal saline group. (p<0.0001) Similarly, both PR and MAP were significantly increased during extubation in both the groups. (p<0.0001) However, the rise of both the parameters in lignocaine group was significantly less as compared to normal saline group. (p<0.0001) VAS scores in immediate post operative period were better in lignocaine group than normal saline group. The mean pain free period was less than an hour in normal saline group, while it was approximately 4 hours in lignocaine group. (p<0.0001)
 Conclusions: This study concluded that i.v infusion of lignocaine had significantly increased the pain free period post operatively. So those who are not affordable for epidural block, lignocaine i.v infusion is better alternative for post operative analgesia.

A new abdominal drainage tube fixation method for 3-port laparoscopic cholecystectomy improves patients’ postoperative quality of life

ObjectiveLaparoscopic surgery has become a routine general surgery with many advantages, such as alleviating abdominal pain. However, postoperative pain caused by abdominal drainage tubes has attracted little attention from medical staff. The aim of this study was to explore the influence of a new abdominal drainage tube fixation method for 3-port laparoscopic cholecystectomy (LC) surgery on patients’ postoperative quality of life. MethodsPatients who underwent 3-port LC surgery with abdominal drainage tubes in the Department of Hepatobiliary Surgery of Linyi People’s Hospital from March 1, 2023 to October 31, 2023 due to gallstones with chronic cholecystitis were selected for this study. The patients were randomly divided into an experimental group and a control group. In the experimental group, the new abdominal drainage tube fixation method was used, while in the control group, the traditional method was used. Afterward, the patients evaluated their quality of life in terms of pain, activity, recovery time, and mental health status. The exudate around the patient’s drainage tube was collected and sent for bacterial culture and analysis. ResultsA total of 139 patients were randomly divided into an experimental group (70 patients) and a control group (69 patients). The patients’ baseline characteristics were not significantly different. The patients in the experimental group had better outcomes in quality of life, with higher pain scores (24.03 ± 2.37 vs. 15.48 ± 2.29, p < 0.001) and activity scores (20.57 ± 1.78 vs. 14.13 ± 1.43, p < 0.001), and a shorter postoperative recovery time (2.36 ± 0.68 d vs. 2.96 ± 1.34 d, p < 0.001). The same results were shown in linear regression analysis scores of the two groups. The positive rate of bacterial culture in the exudate around the patient’s drainage tube in the experimental group was significantly lower than that in the control group (12.9% vs. 43.5%, p < 0.001); and furthermore, the positive rate of conditional pathogenic bacteria was even lower (7.1% vs. 33.3%, p < 0.001) in the experimental group than in the control group. ConclusionThis new abdominal drainage tube fixation method can effectively promote patient rehabilitation and improve the quality of life for patient following 3-port LC surgery with abdominal drainage tubes, increasing the clinical application value of this technique.

Effect of Dexmedetomidine Premedication on Sevoflurane Requirement using BIS during General Anaesthesia in Laparoscopic Cholecystectomy

Background: Dexmedetomidine is a highly selective α2-adrenoreceptor agonist with sedative, anxiolytic and analgesic properties without any respiratory depression. It decreases the requirement of volatile anaesthetics with better hemodynamic stability in surgical patients. We avoided the risk of awareness under anaesthesia by using Bispectral index. Aims: To evaluate the efficacy of Dexmedetomidine pre-medication on Sevoflurane requirement and to assess the haemodynamic stability during elective laparoscopic cholecystectomy surgeries. Methods: Randomized double-blind control study. Design: Forty eight patients were randomly allocated into two groups. Group A received saline infusion and Group 2 received Dexmedetomidine infusion in a dose of 1µg/kg over 15 min before induction. Vital parameters and bispectral index were noted throughout the surgery. Patients were induced and intubated as per the standard protocol and maintained with Oxygen &amp; Nitrous oxide (1 litre Oxygen + 2 litre Nitrous oxide) with Sevoflurane concentration adjusted to achieve BIS values of 45–55. Demographic profile, hemodynamic parameters total Sevoflurane consumption were noted. Statistical Analysis: Statistical analysis was performed using SPSS software version 22.0. Percentage analysis was done for qualitative data. Parametric data were compared using an unpaired t-test. Nonparametric data were compared with Fisher’s exact test or Chi-square test. Results: Mean Sevoflurane consumption in Group A and Group B were 0.379 ± 0.10, 0.169 ± 0.05 ml/min respectively with P&lt;0.001 which was statistically significant. A 55.4% reduction in Sevoflurane consumption was found in patients receiving Dexmedetomidine premedication. Conclusions: Dexmedetomidine premedication is useful to reducing Sevoflurane consumption during general anesthesia and it provides better haemodynamic stability.

The effect of upper transabdominal plane block on diaphragm thickness in adult patients after laparoscopic cholecystectomy operation.

In this prospective and observational study, our objective was to examine the impact of subcostal transversus abdominis plane (SubTAP) block, along with intravenous analgesia techniques, on diaphragm thickness and post-operative pain following laparoscopic cholecystectomy. This study examined laparoscopic cholecystectomy patients aged 18-60 years with an American Society of Anesthesiologist score of 1-2. This study divided patients into Group 1 for SubTAP block and Group 2 for intravenous analgesia. This study had 67 patients, at least 30 from each group. Thus, diaphragm thicknesses and Visual Analogue Scale (VAS) values were compared between regional anaesthesia and intravenous analgesia groups. Pre-operative data showed no statistically significant changes between the groups, although post-extubation inspiratory thickness was closer to baseline in Group 1 patients who received regional block. The groups had different outcomes after extubation and at the post-operative 30th min (P = 0.028 and P = 0.001, respectively). There was also a significant difference in post-operative oxygen saturation and VAS scores (P = 0.001). Our receiver operating characteristic analysis determined that the threshold values for VAS parameters of 2 or 3 were 0.28 cm in inspiration, 0.18 cm in expiration and 1.29 as i/e ratio. Significant discomfort was defined as diaphragm parameter values below these limits. We found that the earlier return of diaphragmatic functions to baseline was associated with diaphragm thickness. According to the measurements made in the post-operative care unit, the regional block group effectively prevented the loss of diaphragm function.

Impact of Dexmedetomidine on Postoperative Nausea and Vomiting in Opiate-Addicted Patients Undergoing Elective Laparoscopic Cholecystectomy: A Randomized, Placebo-Controlled Clinical Trial

Background: Postoperative Nausea and Vomiting (PONV) is one of the most common complications of general anesthesia, moreover opioid addiction increases the risk of PONV. Hence, this study evaluates the effect of administering dexmedetomidine infusion as an intraoperative analgesic on PONV in opium-addicted patients who underwent elective laparoscopic cholecystectomy.&#x0D; Methods: In a randomized clinical trial, 100 opium-addicted patients who were candidates for elective laparoscopic cholecystectomy surgery under general anesthesia were studied in two groups of 50 participants. The intervention group received dexmedetomidine infusion 10 min after induction of anesthesia until the end of surgery. The placebo group received normal saline at the same time. The rate of PONV was compared between the two groups.&#x0D; Results: Both groups had no significant difference in terms of hemodynamic parameters during surgery, including pulse rate, systolic and diastolic blood pressure, and duration of anesthesia. In the dexmedetomidine group, patients had less PONV than the control group, and this difference was significant (p=0.0164).&#x0D; Conclusion: Dexmedetomidine administration during laparoscopic surgery can reduce PONV, especially in patients addicted to opium.&#x0D;

Zinc Transporter ZnT1 mRNA Expression Is Negatively Associated with Leptin Serum Concentrations but Is not Associated with Insulin Resistance or Inflammatory Markers in Visceral Adipose Tissue.

The aim of this study was to evaluate the relationship between biomarkers of chronic inflammation, insulin resistance, and zinc transporter ZnT1 expression in human visceral adipose tissue. Visceral adipose tissue obtained from 47 adults undergoing laparoscopic surgery for cholecystectomy was used to analyze ZnT1 mRNA expression by RT-qPCR. ZnT1 mRNA levels were compared between subjects with normal weight, overweight, and obesity. A significantly lower ZnT1 expression was observed in overweight and obesity compared with normal-weight subjects (p = 0.0016). Moreover, subjects with normal weight had significantly higher serum zinc concentration (97.7 ± 13.1mg/L) than subjects with overweight (87.0 ± 12.8mg/L) and obesity (83.1 ± 6.6mg/L) (p = 0.002). Pearson test showed a positive correlation between serum zinc concentrations and ZnT1 mRNA expression in visceral adipose tissue (r = 0.323; p = 0.031) and a negative correlation with body mass index (r = - 0.358; p = 0.013). A linear regression model was used to analyze the associations between ZnT1 mRNA expression and serum zinc levels, insulin resistance (HOMA2-IR), serum adipokines (leptin and adiponectin), and serum inflammation biomarkers (tumor necrosis factor alpha, interleukin-6, and C-reactive protein). Interestingly, leptin concentrations were negatively associated with ZnT1 mRNA expression (p = 0.012); however, no significant associations were found for the rest of the analyzed variables. Future research is needed to analyze the causality of negative association between ZntT1 expression in visceral adipose tissue and leptin.

A COMPARISON OF INTRAPERITONEAL INSTILLATION OF ROPIVACAINE AND ROPIVACAINE WITH DEXMEDETOMIDINE FOR POSTOPERATIVE ANALGESIA FOLLOWING LAPAROSCOPIC CHOLECYSTECTOMY: A PROSPECTIVE STUDY

Objective: laparoscopic cholecystectomy surgeries are having advantages over open cholecystectomy with less pain and quick recovery. Intraperitoneal route of administration of a local anaesthetic is a cheap, easy and non-invasive method of reducing the intensity of post laparoscopic pain. This study compared the postoperative analgesic effect of intraperitoneal instillation of ropivacaine 0.5% and ropivacaine 0.5% with dexmedetomidine (1µg/kg) in patients undergoing laparoscopic cholecystectomy under general anaesthesia.&#x0D; Methods: Total 86 patients were divided equally in 2 groups. Patients in group R received 20 ml 0.5% isobaric ropivacaine hydrochloride+5 ml NS where in Group RD, patients received 20 ml 0.5% isobaric ropivacaine hydrochloride with 1µg/kg dexmedetomidine hydrochloride. Solution was diluted with normal saline to make a total volume 25 ml. Hemodynamic parameters were noted during surgery Postoperatively, patient was assessed for pain using the visual analogue scale (VAS) at 30 min, then 2,4,8,12 and 24 h. Total analgesic consumption in the first 24 h also compared.&#x0D; Results: Baseline demographic profile of study participants were similar. Mean duration of analgesia was significantly higher in group RD (10.05±6.916 h) as compared to group R (5.59±6.8) (p=0.003). Mean dose of rescue analgesia was significantly higher in group R (130.81±61.44) as compared to group RD (75±36.6) (p&lt;0.001). VAS score was significantly higher in group R as compared to group RD at different time intervals.&#x0D; Conclusion: We concluded that intraperitoneal Ropivacaine with Dexmedetomidine produced postoperative analgesia better than ropivacaine alone.

Surgical Safety Checklist as an optimal organizational model in ensuring the maximum degree of preparedness for intraoperative incidents (case report)

Objective. The use of checklists for quality and safety control of medical care is an effective tool for reducing the frequency of errors, dangers and complications in any section of medical practice.The aim is to demonstrate the possibilities of minimizing and leveling the potential risks accompanying surgical intervention using the example of routine application of the surgical safety checklist.Object and methods. Patient A., 55 years old, was admitted to the emergency department of Samara City Clinical Hospital №1 named after N.I. Pirogov on 24.04.2023. with complaints of pain in the right upper abdomen, nausea, vomiting, general weakness. The diagnosis was Cholelithiasis, acute calculous cholecystitis with the formation of a perivesical abscess. It required laparoscopic cholecystectomy operation. While filling in the surgical safety checklist (SSC) and analyzing possible intraoperative incidents, the attending physician executed an informed voluntary consent for transfusion of donor blood components. The corresponding components were ordered. Having weighted up the potential intraoperative risks specified in the part "Before anesthesia" of SSC, the anesthesiologist installed a catheter into one of the central veins and performed the urine bladder catheterization. Surgical intervention was complicated by bleeding, which required conversion of surgical approach. Upper median laparotomy, cholecystectomy, surgical hemostasis were performed. Total blood loss was 1000 ml, plasma and red blood cell were donated to the patient. The operation was completed by drainage of the subhepatic space and suturing of surgical wounds.Results. The clinical case describes the importance of a team approach at the stage before the operation, as well as the role of all specialists provided life support and medical care for the patient. It results from attentive work with the checklist which shows a clear liability for each member of the operating team at different stages of preparation and treatment of a surgical patient.Conclusions. The development of a culture of surgical safety is an important way to minimize the risks associated with surgical intervention for each individual patient and for the institution by optimizing the work of operating units.

A novel comparison of erector spinae plane block and paravertebral block in laparoscopic cholecystectomy.

Erector spinae plane block is an updated method than paravertebral block, possessing a lower risk of complications. This study aimed to compare erector spinae plane and paravertebral blocks to safely reach the most efficacious analgesia procedure in laparoscopic cholecystectomy cases. The study included 90 cases, aged 18-70 years, classified as American Society of Anesthesiologists I-II, who underwent an laparoscopic cholecystectomy procedure. They were randomly separated into three groups, namely, Control, erector spinae plane, and paravertebral block. No block procedure was applied to Control, and a patient-controlled analgesia device was prepared containing tramadol at a 10 mg bolus dose and a 10-min locked period. The pain scores were recorded with a visual analog scale for 24 h postoperatively. The visual analog scale values at 1, 5, 10, 20, and 60 min at rest and 60 min coughing were found to be significantly higher in Control than in paravertebral block. A significant difference was revealed between Control vs. paravertebral block and paravertebral block vs. erector spinae plane in terms of total tramadol consumption (p=0.006). Total tramadol consumption in the first postoperative 24 h was significantly reduced in the paravertebral block compared with the Control and erector spinae plane groups. Sonography-guided-paravertebral block provides sufficient postoperative analgesia in laparoscopic cholecystectomy surgery. Erector spinae plane seems to attenuate total tramadol consumption.

The Effects of Early Mobilization on Pain and Quality of Recovery in Patients Undergoing Laparoscopic Cholecystectomy Surgery:

Objective: This study was conducted to determine the effects of early mobilization on pain and quality of recovery in patients undergoing laparoscopic cholecystectomy.&#x0D; Materials and methods: Pretest-posttest experimental design with control group. This study was carried out at the General Surgery Inpatient Clinic of a state hospital between April 2021 and January 2022. A total of 90 patients were included in the study. Starting with two hours after surgery, the patients in the experimental group were mobilized at least 6 times in 24 hours. A “Patient Description Form”, the “Visual Analog Scale for Pain”, and the “Quality of Recovery-40 Questionnaire” were used to collect data. &#x0D; Results: The introductory and medical characteristics of the patients in the intervention and control groups were similar. There was no significant difference between the pain and recovery quality mean scores of the patients in the two groups at the 2nd postoperative hour. The mean pain scores of the patients in the intervention group at the 24th hour and on the 15th day after surgery were found to be significantly lower than the scores of those in the control group. It was found that the mean recovery quality scores of the patients in the intervention group at the 24th hour and on the 15th day after surgery were also higher than those of the patients in the control group.&#x0D; Conclusions: It was determined that early mobilization reduced the level of pain and increased the quality of recovery in laparoscopic cholecystectomy patients.

Comparison of the Effects of Body Acupressure and Ear Acupressure on Shoulder Pain in Iranian Patients Undergoing Laparoscopic Cholecystectomy: A Randomized Controlled Trial

Shoulder pain after laparoscopic cholecystectomy surgery is one of the important complications that can increase patients’ discomfort and their length of stay at the hospital. This study aimed to compare the effects of body acupressure and ear acupressure on shoulder pain in patients undergoing laparoscopic cholecystectomy. Total of 101 patients participated in this randomized controlled clinical trial in 2022. They completed the demographic information form and the Spielberger State-Trait Anxiety Inventory. Then, they were assigned into ear acupressure, body acupressure, and control groups through block randomization. The control group did not receive any intervention. The amount of shoulder pain in patients was recorded in all three groups by using the VAS one (T1), four (T2), and eight (T3) hours after the intervention. The mean shoulder pain score in the ear acupressure group was lower than that in the body acupressure group and the control group in T1 (P&lt;0.001). The median shoulder pain score in the body acupressure group was lower than that in the control group at T2 (P&lt;0.001); the median pain score in the ear acupressure group was significantly lower than that in the other two groups at T2 (P&lt;0.001). The median pain score in the control group was higher than that in the body acupressure and ear acupressure groups at T3 (P&lt;0.001). We observed no statistically significant difference between the body acupressure and ear acupressure groups at T3 (P= 0.12). Statistical analysis showed no difference between the mean anxiety scores of patients in the control, body acupressure, and ear acupressure groups (Z=1.41, P=0.49). Body acupressure and ear acupressure were effective in reducing shoulder pain after laparoscopic cholecystectomy, but ear acupressure was more effective and it showed its analgesic effect faster than body acupressure.

Outcome Predictors of Percutaneous Cholecystostomy As Definitive Versus Bridging Treatment for Acute Cholecystitis.

Introduction Percutaneous cholecystostomy (PC) is a treatment option for patients with acute cholecystitis (AC) who are too unwell, or too morbid for laparoscopic cholecystectomy (LC). Some patients have PC as a definitive treatment, whereas others have PC as a bridging treatment prior to LC. The aim of this study is to investigate patient characteristics and mortality among those who received PC as definitive treatment versus bridging treatment. Methods Our study retrospectively reviewed all patients treated with PC for AC from February 2019 to November 2022 at the Torbay and South Devon NHS Foundation Trust, Torquay, England. Fifty patients underwent PC for AC, with 48 patients having follow-up data available for analysis. Of these, 26 patients (54%) only received PC (definitive PC), and 22 patients (46%) later underwent LC (bridging LC). Results In this study, 68.8% of the patients were male, with a mean age of 76 ± 9 years. The overall mean Charlson Comorbidity Index (CCI) score was 4.96 ± 1.12, and the mean American Society of Anesthesiologists (ASA) score was 2.83 ± 0.36. The median PC drain duration was 42 days. Six patients (12.5%) had a recurrence of AC with a mean of 57 days onset after PC insertion. Twelve patients (25%) experienced PC complications: 11 (23%) were minor, involving pain or a dislodged tube, and one (2%) was major, resulting in a subhepatic abscess. The median duration from PC insertion to LC surgery was 50.5 days. The bridging LC cohort had a 30-day and one-year mortality of 0%, while the definitive PC cohort had a 30-day mortality of 30.8% (eight patients) and a one-year mortality of 46.1% (12 patients). The bridging LC cohort compared to the definitive PC cohort had a significantly lower CCI (4.39 vs 5.57, p<0.05), and a significantly lower ASA (2.61 vs 3.04, p<0.05). The one-year survival cohort compared to the 30-day mortality cohort had significantly lower ASA (2.71 vs 3.25 p<0.05), and a non-significantly lower CCI (4.66 vs 5.86 p=0.094). The presence of negative predictive factors of respiratory dysfunction and hyperbilirubinemia had higher 30-day and 90-day mortality rates of 31.3% and 37.5%, compared to their absence of 9.4% and 21.4% respectively. Conclusion Our results demonstrate that PC is a safe procedure with a high success rate and low complications. We showed that PC is an effective treatment option for bridging a select cohort of patients to receive a delayed LC. Furthermore, the data suggests ASA and CCI scoring can be used as clinical adjuncts to assess whether bridging patients from PC to LC is appropriate. Finally, ASA, respiratory dysfunction, and hyperbilirubinemia can be used as significant negative predictors of post-PC mortality.

HPB P49 Implementation of a standardised operation note template using the Getting It Right First Time (GIRFT) and Royal College of Surgeons of England (RCS) best practice guidance to improve the quality of laparoscopic cholecystectomy documentation

Abstract Background Getting it right first time (GIRFT) in partnership with the Royal College of Surgeons of England (RCS) have published advice on aspects of surgery which should be documented in the laparoscopic cholecystectomy (LC) operation record. This is following calls to enhance the accuracy and value of operative records coupled with a lack of existing recommended minimal standards. Operation notes are fundamental for communication of patient care and in the review of operations following adverse events or patient complaints. Methods We reviewed 20 operation notes to assess adherence to the guidance. Some aspects of the guidance were omitted if expected to be documented elsewhere in the patient records, 28 of 32 points were reviewed. An operation note template was created and implemented then a further 20 operation notes were reviewed. Results Initially, the mean completeness of guidance items was 39%. 6 of the 20 operation notes documented that the ports were inserted under direct vision; 8 documented that a critical view of safety was achieved; 13 documented the spillage/non spillage of bile or stones; 16 documented removal of ports under direct vision and none included all aspects of the post-operative plan. Following implementation of the template, compliance improved across all items. Conclusions There is scope to improve the documentation of LC, particularly in areas linked to common intraoperative and postoperative complications. Implementation of a standardised operation note template is an effective way of improving the documentation of laparoscopic cholecystectomy.

OGBN P34 Telemedicine clinics are a safe and feasible alternative to preoperative face-to-face assessments for day case laparoscopic cholecystectomy surgery: a retrospective cohort study

Abstract Background The telemedicine clinic for follow ups after minor surgical procedures in general surgery is now ubiquitously considered a standard of care. However, this method of consultation is not the mainstay for preoperative assessment and counselling of patients for common surgical procedures such as laparoscopic cholecystectomy. The aim of this study was to assess the safety of assessing and counselling patients in the telemedicine clinic without a physical encounter for laparoscopic cholecystectomy. Methods We conducted a retrospective analysis of patients who were booked for laparoscopic cholecystectomy for benign gallbladder disease via general surgery telemedicine clinics from March 2020 to November 2021. The primary outcome was the cancellation rate on the day of surgery. The secondary outcomes were complication and readmission rates. Statistical analysis was done using JASP 0.16.2 software. Results We identified 206 cases booked for laparoscopic cholecystectomy from telemedicine clinics. 6.8% of patients had surgery cancelled on the day of surgery. Only one such cancellation was deemed avoidable as it may have been prevented by a face-to-face assessment. Severe postoperative adverse events (equal or higher than grade 3) were observed in 1% of patients. 30-day readmission rate was 11%. Conclusions Our series showed that it is feasible to assess and counsel patients for laparoscopic cholecystectomy remotely with a minimal cancellation rate on the day of operation. Further work is needed to understand the effect of remote consultations on patient satisfaction, environmental impact, and healthcare economics to support its routine use in general surgery.

HPB P45 Assessment of quality of documentation for Laparoscopic cholecystectomy: a quality improvement project

Abstract Background Laparoscopic cholecystectomy is one of the most common procedures carried out in a General Surgery unit both in emergency and elective theatres. Getting It Right First Time (GIRFT) and the Royal College of Surgeons England (RCS) have made best practice recommendations to ensure adequate documentation of laparoscopic cholecystectomy operation details for good clinical communication with colleagues and to aid in the review of operations after a patient complaint. This is a Quality Improvement Project (QIP) in a NHS Trust in West Midlands to assess the quality of documentation in view of the recommendations made by GRIFT and RCS. Methods Documentation including operative note, clinical noting, ward round entries, laboratory results, imaging records and clinical letters were reviewed for 100 consecutive laparoscopic cholecystectomies carried out during the month of May 2023 and assessed against a checklist based on recommendations made by GIRFT and RCS. Following the audit, a multifaceted intervention is planned, including teaching presentations and an electronic documentation template. A re-audit following interventions will be carried out in July, 2023. Results There was mixed compliance with GIRFT recommendations. Some recommendations, including indication for surgery, consent, WHO checklist, and surgeon details were followed in all cases. Documentation shortcomings included missing details on technique for pneumoperitoneum with 19% of operation notes failing to mention this detail ,intraoperative drug administration (54%), intraabdominal pressure levels (95%), Number of clips applied (66%), gall bladder retrieval method and port used for the purpose (38%), confirmation of port removal under vision (32%), hemostasis achievement (12%), fascia closure (26%), critical view of safety/safe view assessment (49%), anesthetist names (62%), and first surgeon's signature (41%). Conclusions We found significant shortcomings in documentation of patients undergoing laparoscopic cholecystectomy. This documentation needs improvement and standardization so that it meets the GIRFT and RCS Guidelines.

Laparoscopic Cholecystectomy Effects on Renal Function Tests Among Patients Undergoing the Surgery in Ali Ibn Abi Taleb Hospital in Zahedan (South East of Iran) In 2018.

Background: Laparoscopic Cholecystectomy, one of the most common elective surgical procedures, is a minimally invasive surgical procedure for patients with gallbladder diseases. Objectives: This study aimed to evaluate the effect of laparoscopic cholecystectomy on Renal function Tests among patients undergoing the surgery in Ali Ibn Abi Taleb Hospital in Zahedan (South east of Iran). Methods: Following a quasi-experimental design, 21 cases scheduled for laparoscopic cholecystectomy for whatever reasons at Ali Ibn Abi Taleb Hospital in Zahedan (Iran) were selected. To study the serum levels Renal function Tests, blood samples were collected at three stages, i.e., before the surgery (time point 1), 30 minutes after pumping the carbon dioxide gas into the abdomen (time point 2), and 30 minutes after removing the last port from the abdomen (time point 3). Data were analyzed using repeated measures. Results: According to the findings, laparoscopic cholecystectomy surgery only had a significant effect on the BUN at the 99% confidence level. Also, BUN was increased and significantly differed at time points 2 (30 minutes after pumping) and 3 (30 minutes after removing the port) compared to time point 1 (30 minutes before the surgery). Conclusions: Generally, it can be argued that despite observing some variations in the BUN test during the laparoscopic surgery, the Cr level did not change. Hence, it can be considered as a safe surgical intervention for renal functions.

Does previous gastrectomy history affect the surgical outcomes of laparoscopic cholecystectomy?

PurposeThis current study aimed to explore whether gastrectomy history influenced surgical outcomes while undergoing laparoscopic cholecystectomy (LC).MethodsThe PubMed, Embase, and Cochrane Library databases were searched for eligible studies from inception to April 29, 2023. The Newcastle–Ottawa Scale (NOS) was adopted to assess the quality of included studies. The mean differences (MDs) and 95% confidence intervals (CIs) were calculated for continuous variables, and the odds ratios (ORs) and 95% CIs were calculated for dichotomous variables. RevMan 5.4 was used for data analysis.ResultsSeven studies enrolling 8193 patients were eligible for the final pooling up analysis (380 patients in the previous gastrectomy group and 7813 patients in the non-gastrectomy group). The patients in the gastrectomy group were older (MD = 11.11, 95%CI = 7.80–14.41, P < 0.01) and had a higher portion of males (OR = 3.74, 95%CI = 2.92–4.79, P < 0.01) than patients in the non-gastrectomy group patients. Moreover, the gastrectomy group had longer LC operation time (MD = 34.17, 95%CI = 25.20–43.14, P < 0.01), a higher conversion rate (OR = 6.74, 95%CI = 2.17–20.26, P = 0.01), more intraoperative blood loss (OR = 1.96, 95%CI = 0.59–3.32, P < 0.01) and longer postoperative hospital stays (MD = 1.07, 95%CI = 0.38–1.76, P < 0.01) than the non-gastrectomy group.ConclusionPatients with a previous gastrectomy history had longer operation time, a higher conversion rate, more intraoperative blood loss, and longer postoperative hospital stays than patients without while undergoing LC. Surgeons should pay more attention to these patients and make prudent decisions to avoid worse surgical outcomes as much as possible.

A Comparison of the Recovery Profile of Dexmedetomidine When Administered by Different Routes in Patients Undergoing Laparoscopic Cholecystectomy – A Randomized Controlled Trial

Laparoscopic cholecystectomy is a minimally invasive procedure that demands a safe and fast-tracking anesthesia plan. A faster and smoother recovery of patients from anesthesia after a surgical procedure is critical for early discharge. Dexmedetomidine is a short-acting α2 agonist with analgesic, sedative, and anxiolytic properties. However, it is associated with prolonged sedation when administered through an intravenous route, thereby prolonging the recovery time from anesthesia. We conducted this study to compare the time to extubation after anesthesia when dexmedetomidine was administered through the conventional intravenous route and an interfascial transversus abdominus plane (TAP) block and rectus sheath (RS) block in patients undergoing laparoscopic cholecystectomy surgeries under general anesthesia. In addition, we also studied postoperative pain using the Visual analog scale (VAS). This study is a double-blinded, randomized controlled clinical trial conducted on 54 patients undergoing laparoscopic cholecystectomy. Patients were allocated to two groups. Group C received 50 micrograms of dexmedetomidine intravenously. Patients in group T received 50 micrograms of dexmedetomidine as an adjuvant to the 0.3% ropivacaine administered through the TAP block and RS block. The mean time for extubation in group C was 10.87 ± 1.71 minutes, and in group T was 4.37 ± 0.25 minutes, which was significant (p &lt; 0.05, 95% CI - 5.83 to 7.17). In addition, the median postoperative VAS in group T was significantly lower at six hours, 12 hours, and 18 hours postoperatively. Hence, we conclude that dexmedetomidine, administered in the interfascial plane for laparoscopic cholecystectomy surgery, provides a better recovery profile from general anesthesia and good postoperative pain relief.

COMPARISON OF SAFETY OF MINILAPAROSCOPIC AND CONVENTIONAL LAPAROSCOPIC CHOLECYSTECTOMY

Abstract. Aim: to assess the safety of mini-laparoscopic cholecystectomy (MLC) compared to traditional laparoscopic cholecystectomy (LC) based on a critical view of safety (CVS).&#x0D; Materials and methods: an analysis of 46 video recordings of MLC surgeries and 156 LC surgeries performed for chronic calculous cholecystitis and gallbladder polyps between 2015 and 2022 was conducted, using the concept of CVS and the quality of its achievement. An analysis of anatomical variations was also performed.&#x0D; Results and discussion: the average age was 38.5 years in the MLC group and 53.8 years in the LC group, with an average operation time of (59.4±2.13) minutes and (63.01±2.01) minutes, respectively. CVS was achieved in 97.8 % of cases in MLC and 93.0 % in LC. Anatomical variations were present in 31.1 % of cases in MLC and 30.1% in LC. There were no complications of MLC, conversions from MLC to LC, or open surgery.&#x0D; Conclusions: The frequency of achieving CVS in MLC was higher than in LHE (97.8 % vs. 93.0 %). Anatomical variations of the biliary system should always be considered for the safe cholecystectomy. MLC is a safe technique that is not inferior to standard LCE in elective surgery in patients with a normal BMI, and at the same time has better cosmetic results.
