Retrospective validation of parkland grading scale in a Latin-American high-volume center.

BACKGROUND: Increased complication rates following laparoscopic cholecystectomies have been described, likely related to surgical difficulty, anatomical variations, and gallbladder inflammation severity. Parkland Grading Scale (PGS) stratifies the severity of intraoperative findings to predict operative difficulty and complications. This study aims to validate PGS as a postoperative-outcome predictive tool, comparing its performance with Tokyo Guidelines Grading System (TGGS). METHODS: This is a single-center retrospective cohort study where PGS and TGGS performances were evaluated regarding intraoperative and postoperative outcomes. Both univariate and bivariate analyses were performed on each severity grading scale using STATA-SE 16.0 software. Additionally, we proposed a Logistic Regression Model for each scale. Their association with outcomes was compared between both scales by their Receiver Operating Characteristic Curve. RESULTS: 400 Patients were included. Grade 1 predominance was observed for both PGS and TGGS (47.36% and 25.3%, respectively). A positive association was observed between higher PGS grades and inpatient postoperative care, length of stay, ICU care, and antibiotic requirement. Based on the area under the ROC curve, better performance was observed for PGS over TGGS in the evaluated outcomes. CONCLUSION: PGS performed better than TGGS as a predictive tool for inpatient postoperative care, length of stay, ICU, and antibiotic requirement, especially in severe cases.

Comparison of the safety and effectiveness of different surgical timing for acute cholecystitis after percutaneous transhepatic gallbladder drainage: a systematic review and meta-analysis.

BACKGROUND: To compare the efficacy and safety of laparoscopic cholecystectomy (LC) in the treatment of acute cholecystitis (AC) at different time points after percutaneous transhepatic gallbladder drainage (PTGBD). METHODS: PubMed, EMBASE, Cochrane Library, and Web of Science were searched from database inception to 1 May 2022. The last date of search was the May 30, 2022. The Newcastle-Ottawa scale (NOS) was used to conduct quality assessments, and RevMan (Version 5.4) was used to perform the meta-analysis. RESULTS: A total of 12 studies and 4379 patients were analyzed. Compared with the < 2-week group, the ≥ 2-week group had shorter operation time, less intraoperative blood loss, shorter postoperative hospital stay, lower rate of conversion to laparotomy, and fewer complications. There was no statistical difference between the two groups regarding bile duct injury, bile leakage, and total cost. CONCLUSIONS: The evidence indicates that the ≥ 2-week group has the advantage in less intraoperative blood loss, minor tissue damage, quick recovery, and sound healing in treating AC. It can be seen that LC after 2 weeks is safe and effective for AC patients who have already undergone PTGBD and is recommended, but further confirmation is needed in a larger sample of randomized controlled studies.

Relationship between ANI and qNOX and between MAC and qCON during outpatient laparoscopic cholecystectomy using remifentanil and desflurane without muscle relaxants: a prospective observational preliminary study.

This study was designed to investigate qCON and qNOX variations during outpatient laparoscopic cholecystectomy using remifentanil and desflurane without muscle relaxants and compare these indices with ANI and MAC. Adult patients undergoing outpatient laparoscopic cholecystectomy were included in this prospective observational study. Maintenance of anesthesia was performed using remifentanil targeted to ANI 50-80 and desflurane targeted to MAC 0.8-1.2 without muscle relaxants. The ANI, qCON and qNOX and desflurane MAC values were collected at different time-points and analyzed using repeated measures ANOVA. The relationship between ANI and qNOX and between qCON and MAC were analyzed by linear regression. The ANI was comprised between 50 and 80 during maintenance of anesthesia. Higher values of qNOX and qCON were observed at induction and extubation than during all other time-points where they were comprised between 40 and 60. A poor but significant negative linear relationship (r2 = 0.07, p < 0.001) was observed between ANI and qNOX. There also was a negative linear relationship between qCON and MAC (r2 = 0.48, p < 0.001) and between qNOX and remifentanil infusion rate (r2 = 0.13, p < 0.001). The linear mixed-effect regression correlation (r2) was 0.65 for ANI-qNOX and 0.96 for qCON-MAC. The qCON and qNOX monitoring seems informative during general anesthesia using desflurane and remifentanil without muscle relaxants in patients undergoing ambulatory laparoscopic cholecystectomy. While qCON correlated with MAC, the correlation of overall qCON and ANI was poor but significant. Additionally, the qNOX weakly correlated with the remifentanil infusion rate. This observational study suggests that the proposed ranges of 40-60 for both indexes may correspond to adequate levels of hypnosis and analgesia during general anesthesia, although this should be confirmed by further research.

Local infiltration versus laparoscopic-guided transverse abdominis plane block in laparoscopic cholecystectomy: double-blinded randomized control trial.

BACKGROUND: Transverse abdominal plane block (TAP) is a new technique of regional block described to reduce postoperative pain in laparoscopic cholecystectomy (LC). Recent reports describe an easy technique to deliver local anesthetic agent under laparoscopic guidance. METHODS: This randomized control trial was designed to compare the effectiveness of additional laparoscopic-guided TAP block against the standard full thickness port site infiltration. 45 patients were randomized in to each arm after excluding emergency LC, conversions, ones with coagulopathy, pregnancy and allergy to local anesthetics. All cases were four ports LC. Interventions-Both groups received standard port site infiltration with 3-5 ml of 0.25% bupivacaine. The test group received additional laparoscopic-guided TAP block with 20 ml of 0.25% bupivacaine subcostally, between the anterior axillary and mid clavicular lines. As outcome measures the pain score, opioid requirement, episodes of nausea and vomiting and time to mobilize was measured at 6 hourly intervals. RESULTS: The two groups were comparable in the age, gender, body mass index, indication for cholecystectomy difficulty index and surgery duration. The pain score at 6 h (P = 0.043) and opioid requirement at 6 h (P = 0.026) was higher in the TAP group. These were similar in subsequent assessments. Other secondary outcomes were similar in the two groups. CONCLUSION: Laparoscopic-guided transverses abdominis plane block using plain bupivacaine does not give an additional pain relief or other favorable outcomes. It can worsen the pain scores. Pre registration: The trial was registered in Sri Lanka clinical trial registry-SLCTR/2016/011 ( http://www.slctr.lk/trials/357 ).

Managing iatrogenic bile duct injuries through a multidisciplinary team approach: A SIUT case series.

Iatrogenic injury to the bile duct is one of the most serious and feared complication of cholecystectomy, with a high mortality ranging between 3-12%. The management of such injuries of the bile duct is far more complicated and prolonged than the procedure itself. A retrospective analysis of 36 patients with bile duct injuries (BDI) was conducted over a period of 7 years, from January 2007 to December 2014. Most of their injuries occurred during open cholecystectomy, 22 rather than laparoscopic 14 and were mostly elective surgeries 34. Most injuries were identified postoperatively in 33 (91.6%) patients, at a median of 3.0 days. Among the modalities used to diagnose and treat these patients, endoscopy was performed in 32 of the cases (88.8%), followed by surgery on 17 (47.2%) patients and radiology on 16 (44.4%) cases. Surgery remains the gold standard for treatment of complete transection of bile duct injuries and long term outcomes are usually good. Endoscopy and radiology has an increasing role in the diagnosis and treatment of a leaking (non-transected) bile duct injury.

[Effects of lateral and medial points of thoracic paravertebral nerve block by ultrasound for rapid recovery after laparoscopic cholecystectomy].

Objective: To investigate the effects of ultrasound-guided lateral and medial point blocks of thoracic paravertebral space on the rapid recovery of laparoscopic cholecystectomy. Methods: A total of 90 patients of either sex, aged 18-67 years, weighted 45.10-91.80 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, undergoing elective laparoscopic cholecystectomy were divided into two groups (n=45) using a random number table: lateral point group of thoracic paravertebral space (group A) and medial point group of thoracic paravertebral space (group B). Ultrasound-guided thoracic paravertebral nerve block was performed before induction of general anesthesia. The puncture point of group A was positioned as the intercostal block of the thoracic paravertebral space of the right side of T(6)-T(11), and the puncture point of the group B was positioned as the thoracic paravertebral body of the right side of T(6)-T(11) thoracic paravertebral space. The thoracic paravertebral block was performed with 2 ml of 0.75% ropivacaine per injection for a total of 10 ml. The visual analog scale (VAS) scores of resting pain and active pain at 4, 8, 12 and 24 h after operation were observed. The anus recovery time after surgery and perioperative hypotension were also recorded. Results: The blood pressures in group A were significantly higher than those in group B at 4, 8, 12 and 24 h after operation, which were(73±7) vs (70±7), (78±7) vs (74±7),(82±7) vs (79±7),and (87±7) vs (83±7) mmHg,and the differences were statistically significant (t=2.29, 2.54, 2.33, 2.37, all P<0.05). The VAS scores of resting pain and active pain in group A were significantly higher than those in group B, and the differences were statistically significant (Z=-2.29, -2.51, -2.21, -2.39, -2.53, -2.25, -2.30, -2.24, all P<0.05). The postoperative anal exhaust recovery time of the patients in group A was (21.8±1.9) min that was obvious lower than that in group B which was (22.7±1.9) min with statistically significant difference (t=2.12, P<0.05). There was no significant difference in the incidence of postoperative dizziness, nausea, vomiting, and pruritus (χ(2)=0.28, 0.72, 0.45, 0.21,all P>0.05). Conclusions: In the procedure of thoracic paravertebral block under the guidance of ultrasound, the closer blocking points are to the central axis of the spine, the better the postoperative analgesic effect, but the more obvious the postoperative blood pressure reduction and the longer the anal recovery exhaust time. The further away from the central axis of the spine, the more analgesic effect decreases, but the blood pressure decreases and the anal recovery time is relatively rapid.

[Laparoscopic treatment for incidental gallbladder cancer: a retrospective 10 years study from a single institution].

Objective: To explore the feasibility of laparoscopic treatment for incidental gallbladder cancer(IGBCA) and analyze the factors influencing prognosis. Methods: A retrospective study of 71 patients with IGBCA received laparoscopic treatment at Department of General Surgery, Peking University Third Hospital from January 2007 to December 2016 was conducted,the clinicopathological data and prognosis were analyzed. There were 18 males and 53 females,aged 23 to 81 years. They were divided into two groups based on the presence of intraluminal mass in the gallbladder. Sixty-five of the 71 patients received laparoscopic radical resection, the prognosis of them were compared with 14 patients with open radical resection. Results: Among the 71 patients,65 patients received radical resection,3 patients simple gallbaldder resection and 3 patients palliative resection. Postoperative complications occurred in 6 patients. IGBCA were detected by frozen section in 57 patients,with the accuracy of 96.5%,while the accuracy of T stage is 43.8% in the 48 patients received T stage evaluation during frozen section examination. The T stages based on final pathology were Tis(n=6),T1a(n=5),T1b(n=10),T2(n=46),and T3(n=4).The number of harvested lymph node was 4.7±2.9(range:2-12).There are 14 patients with lymph node metastasis. The 50 patients with intraluminal gallbladder mass include 21 patients with ≤T1b stage and 29 patients with ≥T2 stage, while the 21 patients without intraluminal gallbladder mass are all with ≥T2 stage. The median survival time of the 71 patients was 33 months, with the 5-year cumulative survival rate 67.3%. The 5-year cumulative survival rate is 78.5% for the 65 patients who received radical resection,comparable with those who received open radical resection(P=0.485).Univariate analysis demonstrated that T stage, lymph node metastasis, G grade, lymphovascular invasion, neural invasion, acute cholecystectomy, bile spillage, gallbladder mass and preoperative CA19-9/CEA were the most important prognostic factors(P<0.05). Conclusions: Laparoscopic treatment for IGBCA is feasible, especially for those with intraluminal gallbladder mass. The accuracy of frozen section examination in evaluating T stage is low.

[Expert consensus on standardized processes of ambulatory biliary surgery (2018 edition)].

The definition of ambulatory surgery is that the patient is admitted, operated and discharged within a day (24 hours) , but does not include outpatient surgery. It can shorten the average hospital stay, reduce medical expenses, accelerate the recovery of patients, and has been approved to have great social and economic benefits.The main contents of this consensus include: (1)the establishment of ambulatory biliary surgery system, which involves the facilities building, team building, the construction of management systems, operation management, operation state analysis and benefit evaluation; (2)Patient selection criteria, pre-hospital assessment, surgical scheduling, preoperative education, anesthesia and management of adverse reactions after anesthesia, intraoperative application of general surgical principles and postoperative emergency plans, perioperative nursing; (3)Discharge criteria and pre-discharge assessment, post-discharge follow-up and rehabilitation guidance; (4) quality and safety control index system of ambulatory biliary surgery.The publication of this consensus is conducive to the establishment of ambulatory biliary surgery system, the evaluation of effectiveness and quality control, and the promotion of ambulatory biliary surgery.

DISCHARGE AFTER ELECTIVE UNCOMPLICATED LAPAROSCOPIC CHOLECYSTECTOMY: CAN THE POSTOPERATIVE STAY BE REDUCED?

- The aim of the study was to reevaluate the safety and feasibility of discharge 24 h after elective uncomplicated laparoscopic cholecystectomy. Since the introduction of laparoscopic cholecystectomy in our hospital, the minimum postoperative stay was considered to be two days based on surgeons' experience. The study included 337 operations performed by 21 surgeons during 2016 in the Sestre milosrdnice University Hospital Centre. Conversion to open technique and cases of acute cholecystitis were excluded, while 15 patients had insufficient postoperative data. The mean length of stay was 2.38 (range 1 to 6) postoperative days, median two postoperative days. Serious complications involving suspected drain bile leakage and postoperative hemorrhage occurred in two (0.59%) patients, both in the first 24 h following surgery. One patient required emergency laparotomy on the first postoperative day. Readmission rate was 1.2%. The postoperative minor complication rate was 42 of 337 (12.46%); these included wound infections, urinary tract infections, symptoms included in postcholecystectomy syndrome, etc. The onset of these complications was mostly after postoperative day 3. The data obtained suggest that discharge on the first postoperative day after elective uncomplicated laparoscopic cholecystectomy should be considered safe and can be practiced in our hospital.

[Effect of dexmedetomidine alone for postoperative analgesia after laparoscopic cholecystectomy].

Objective: To investigate the effect of dexmedetomidine alone for postoperative analgesia after laparoscopic cholecystectomy. Methods: Forty patients scheduled for elective laparoscopic cholecystectomy in First Hospital of Ninghai County, American Society of Anesthesiologists (ASA) gradeⅠor Ⅱ, were randomly divided into dexmedetomidine group (Group D, n=20) and fentanyl group (Group F, n=20). The patient controlled analgesia (PCA) pumps were used after the operation. In the group D, the intravenous PCA protocol was dexmedetomidine 0.2 µg·kg(-1)·h(-1) diluted to 100 ml in 0.9% saline. In the group F, the PCA protocol was fentanyl 20 µg /kg diluted to 100 ml in 0.9% saline. Mean arterial pressure (MAP) and heart rate (HR) were recorded at the following time points: before induction of anaesthesia, end of operation and 4, 6, 8, 24, 48 hours after the operation. The pain score on a visual analogue scale (VAS) and the Ramsay sedation score were recorded at 4, 6, 8, 24, 48 hours after the operation. The incidences of postoperative nausea and vomiting (PONV), respiratory depression, dizziness, time to recovery of gastrointestinal function (time to first passage of flatus) and satisfaction with pain control were also recorded. Results: There were no significant difference in the general data of patients, duration of surgery, total dose of intraoperative propofol, fentanyl and sevoflurane, and total fluids during the operation (P>0.05). No patients received rescue analgesic. The MAP and HR values at different time points showed no significant difference between the groups (P>0.05). Similarly, the VAS scores and Ramsay sedation scale at 4, 6, 8, 24, 48 hours after the operation were not significantly different between the groups (P>0.05). The incidence of PONV was significantly reduced in group D, rating as 5%, comparing with 40% in Group F (P<0.05). Patients of Group D experienced a faster gastrointestinal function recovery, and the time to the first passage of flatus were (41.3±10.1) h in Group D and (55.6±11.4) h in Group F (t=-4.195, P<0.05), respectively. The pain treatment satisfactory score (PTSS) in Group D was (8.1±1.3) points, higher than that in Group F (6.1±1.5) points (t=4.426, P<0.05). Meanwhile, there was no statistic difference in the incidence of respiratory depression and dizziness in both groups (P>0.05). Conclusion: Intravenous infusion of dexmedetomidine alone at 0.2 µg·kg(-1)·h(-1) after laparoscopic cholecystectomy not only reduces postoperative pain, but also enhances satisfaction with pain control and improves the recovery of gastrointestinal function.

[Effect of intravenous infusion with lidocaine on rapid recovery of laparoscopic cholecystectomy].

Objective: To investigate the effect of intravenous infusion with lidocaine on rapid recovery of laparoscopic cholecystectomy. Methods: This study was a prospective randomized controlled trial. From February to August 2016 in Affiliated Yiwu Hospital of Wenzhou Medical University, 60 patients scheduled for laparoscopic cholecystectomy under general anesthesia were involved and randomly divided into control group (n=30) and lidocaine group (n=30). Patients in lidocaine group received lidocaine 1.5 mg/kg intravenously before induction and followed by 2.0 mg·kg(-1)·h(-1) to the end of surgery. Patients in control group received equal volumes of saline intravenously. Anesthesia induction in both groups were given intravenous midazolam 0.03 mg/kg, sufentanil 0.2 µg/kg, propofol 2.0 mg/kg and cisatracuium 0.2 mg/kg. Anesthesia was maintained with propofol 0.05-0.20 mg·kg(-1)·min(-1) and remifentanil 0.1-0.5 µg·kg(-1)·min(-1) for laryngeal mask airway which bispectral index (BIS) value maintained at 40-60. BIS, heart rate(HR) and mean arterial pressure(MAP) were recorded before anesthesia induction, before and immediately after laryngeal mask implantation, intraoperative 30 min and anesthesia awake. Pain scores were assessed using visual analogue scales (VAS) at postoperation immediately, 30 min during postanesthesia care unit (PACU), 2, 6, 12, and 24 h after surgery. The time of PACU retention, postoperative ambulation, first intestine venting and discharge were recorded. The dosage of propofol and remifentanil, the frequency of sufentanil used, the incidence of postoperative nausea and vomiting were also recorded. Patient satisfaction was evaluated by using Simple Restoration Quality Score (QoR-9). Results: BIS values before and after laryngeal mask implantation in lidocaine group were 50.50±3.47 and 54.63±1.25 respectively, which was lower than those in control group(54.30±4.78, 55.80±2.33; t=3.542, 2.423, all P<0.05). The VAS score at postoperation immediately, PACU 30 min, postoperative 2, 6, 12 h in lidocaine group were 2.76±0.97, 2.37±0.93, 2.10±1.12, 1.76±0.97, 1.20±0.76 respectively, which was lower than those in control group (3.83±1.34, 3.27±1.26, 3.06±1.20, 2.63±0.88, 1.90±0.84; t=3.528, 3.154, 3.217, 3.603, 3.372, all P<0.05 ). The frequency of additional sufentanil at postoperation immediately and PACU 30 min in lidocaine group was 5(17%), 3(10%), which were less than those in control group(12(40%), 9(30%); χ(2)=4.022, 3.950, all P<0.05). The dosage of propofol and remifentanil in lidocaine group were (4.33±0.75) mg·kg(-1)·h(-1) and (9.00±1.66) µg·kg(-1)·h(-1) respectively, which were less than those in control group ((5.20±1.39) mg·kg(-1)·h(-1) and (10.43±2.20) µg·kg(-1)·h(-1;) t= 2.982, 2.842, all P<0.05). The time of PACU retention, postoperative ambulation and first intestine venting were (39.90 ± 8.06) min, (11.93±1.68) h and (10.16±1.05) h respectively in lidocaine group, which were shorter than those in control group ((48.23±10.04) min, (13.16±1.58) h and (11.13±1.30) h; t=3.514, 2.931, 3.156, all P<0.05). The QoR-9 score in lidocaine group was 15.60±1.07, which was higher than that in control group(14.73±0.74, t=-3.649, P<0.05). There was no significant difference in the incidence of postoperative nausea/vomiting and the discharge time between two groups (all P>0.05). Conclusion: Intravenous infusion of lidocaine can effectively reduce the dosages of propofol and remifentanil, postoperative early VAS score, postoperative ambulation time and first intestine venting time which could improve the satisfaction of patients.

Intra-Hepatic Spillage of Gallstones as a Late Complication of Laparoscopic Cholecystectomy: MR Imaging Findings.

BACKGROUND: Spillage of gallstones in the abdominal cavity may rarely occur during the course of laparoscopic cholecystectomy. Dropped gallstones in the peritoneal and extra-peritoneal cavity are usually asymptomatic. However, they may lead to abscess formation with an estimated incidence of about 0.3%. Common locations of the abscess are in the abdominal wall followed by the intra-abdominal cavity, usually in the sub-hepatic or retro-peritoneum inferior to the sub-hepatic space. CASE REPORT: We hereby describe an unusual case of infected spilled gallstones in the right sub-phrenic space, prospectively detected on abdominal MRI performed two years after laparoscopic cholecystectomy, in a patient with only a mild right-sided abdominal complaint. CONCLUSIONS: This case highlights the role of MRI in suggesting the right diagnosis in cases with vague or even absent symptomatology. In our case the patient's history together with high quality abdomen MRI allowed the correct diagnosis. Radiologists should be aware of this rare and late onset complication, even after many years from surgery as an incidental finding in almost asymptomatic patients.

Postoperative pain after laparoscopic cholecystectomy is not reduced by intraoperative analgesia guided by analgesia nociception index (ANI®) monitoring: a randomized clinical trial.

BACKGROUND: Laparoscopic cholecystectomy frequently results in significant immediate postoperative pain. A new pain monitor, analgesic nociception index (ANI®), based on heart rate variability, has recently been approved for intraoperative nociception monitoring. We designed a single-blind, parallel-group, randomized control trial to test the hypothesis that protocol-driven intraoperative analgesia guided by ANI during laparoscopic cholecystectomy would improve titration of intraoperative analgesics leading to decreased postoperative pain. METHODS: One hundred and twenty consecutive adult participants presenting for elective laparoscopic cholecystectomy were recruited. Participants were randomly allocated by sealed envelope to receive intraoperative morphine either guided by ANI via a protocol (intervention group) or guided by the anaesthetist with ANI concealed (control group). All participants received paracetamol, parecoxib, fentanyl at induction, and local anaesthetic to port sites. The primary endpoint was the presence of moderate/severe pain (visual analogue scale ≥50 mm) at any of the four time points in the first postoperative hour. Secondary endpoints included postoperative rescue morphine. RESULTS: Sixty participants were randomized to each group, and all but one drop-out from the intervention group were analysed. The usage of ANI guidance did not result in a decrease in the rate of moderate/severe pain (50.8% vs 45.0%: difference of -5.8%, 95% confidence interval, -23.7% to 12.1%, P=0.58), or the use of postoperative rescue analgesia. CONCLUSIONS: This randomized control trial of intraoperative ANI-guided morphine administration in elective laparoscopic cholecystectomy failed to show any advantage over the current standard of care, and demonstrated a high level of postoperative pain, despite the use of multimodal analgesia.

Postoperative Pain after Laparoscopic Cholecystectomy in a Tertiary Care Center: A Descriptive Cross-sectional Study.

INTRODUCTION: Laparoscopic cholecystectomy, being minimally invasive, is widely accepted in comparison to open cholecystectomy. The major benefits are small incision, less wound pain, rapid recovery, shorter hospital stay and earlier return to activities. Although, trauma and injury are limited in laparoscopic cholecystectomy; it is not a pain free surgery. Hence, we aimed to find the prevalence of pain at wound site after laparoscopic cholecystectomy at various time intervals in post-operative period. METHODS: The descriptive cross-sectional study was conducted among 125 patients who belonged to American Society of Anesthesiologists grade I & II patients, with diagnosis of symptomatic gallstone disease from October, 2022 to September, 2023 in a tertiary care hospital after ethical approval was obtained from Institutional Review Board (Reference number: MEMG/483/IRC). Total sampling was done in this study. The post-operative pain at wound site was measured at 12, 24, 36 and 48 hours. Data were analyzed using Statistical Package of Social Sciences 21.0. RESULTS: At 12 hours postoperatively, 2 (1.60%) patients complained of severe pain, 120 (96%) patients reported moderate pain and 3 (2.40%) patients expressed their pain as being mild. Likewise, at 24, 36 and 48 hours postoperatively, none of the patients suffered from severe pain. At 24 hours post-operative, 105 (84%) patients reported moderate pain which gradually declined over 48 hours. At 36 and 48 hours post-operative mild pain was reported by 85 (68%) and 117 (93.60%) patients. The moderate pain was complained by 40 (32%) and 8 (6.40%) patients. CONCLUSIONS: The majority of patients suffered from mild to moderate pain after laparoscopic cholecystectomy, the intensity of which decreased over 48 hours.

Comparative study of ambulatory versus inpatient laparoscopic cholecystectomy in Thailand: Assessing effectiveness and safety with a propensity score matched analysis.

Backgrounds/Aims: Ambulatory laparoscopic cholecystectomy (LC) is increasingly recognized for its advantages over the inpatient approach, which advantages include cost-effectiveness and faster recovery. However, its acceptance is limited by patient concerns regarding safety, and the potential for postoperative complications. The study aims to compare the operative and postoperative outcomes of ambulatory LC versus inpatient LC, specifically addressing patient hesitations related to early discharge. Methods: In a retrospective analysis, patients who underwent LC were divided into ambulatory or inpatient groups based on American Society of Anesthesiologists (ASA) classification, age, and the availability of postoperative care. Propensity score matching was utilized to ensure comparability between the groups. Data collection focused on demographic information, perioperative data, and postoperative follow-up results to identify the safety of both approaches. Results: The study included a cohort of 220 patients undergoing LC, of which 48 in each group matched post-propensity score matching. The matched analysis indicated that ambulatory LC patients seem to experience shorter operative times and reduced blood loss, but these differences were not statistically significant (35 minutes vs. 46 minutes, p-value = 0.18; and 8.5 mL vs. 23 mL, p-value = 0.14, respectively). There were no significant differences in complication rates or readmission frequencies, compared to the inpatient cohort. Conclusions: Ambulatory LC does not compromise safety or efficacy, compared to traditional inpatient procedures. The findings suggest that ambulatory LC could be more widely adopted, with appropriate patient education and selection criteria, to alleviate concerns and increase patient acceptance.

Laparoscopic cholecystectomy performed by a surgical care practitioner: a review of outcomes.

INTRODUCTION: Surgical care practitioners (SCPs) are non-medical workers involved in various aspects of the management of surgical patients. The role includes assisting and performing surgical procedures. More than 60,000 laparoscopic cholecystectomies (LC) are performed annually in the UK. With ever-increasing pressure on waiting lists, it is important to look at fully utilising the skills of our entire workforce. We report what we believe is the first published series of LC performed by an SCP. METHODS: A retrospective review of a prospectively collected database was performed. The primary outcome was any complication requiring intervention. Secondary outcomes were minor complications, operative time, length of stay, conversion and readmission. RESULTS: In total, 170 patients were operated on. Indications were biliary colic in 127 (74.7%), cholecystitis in 30 (17.6%) and pancreatitis in 13 (7.6%). Mean operating time was 65min (range 35-152min). Fifty-three operations were assisted by a consultant, 110 by a specialist or associate specialist grade (SAS) doctor and 7 by a core trainee (CT2). Some 139 (81.7%) patients were discharged on the day of surgery and 24 (14.1%) stayed one night in hospital. There were no major complications. Five patients required readmission, three with pain and two with port site infections. There were no conversions or transfusions required. CONCLUSIONS: There is a paucity of published data on surgical outcomes of procedures performed by SCPs. With a structured, supervised approach, SCPs could be trained to take on more complex procedures and further strengthen the surgical workforce. This study demonstrates that elective LC can be safely performed by an appropriately trained and supervised SCP.

Comparative evaluation of blind supraglottic airway device insertion versus videolaryngoscope-guided technique in adults undergoing laparoscopic cholecystectomy.

OBJECTIVES: A videolaryngoscope may decrease the high incidence of aberrant positioning of supraglottic airway devices (SAD) inserted with blind techniques. We aimed to compare Igel insertion characteristics between blind and videolaryngoscope-assisted techniques. METHODS: In this study 70 adult patients scheduled for elective laparoscopic cholecystectomy under general anesthesia were randomly divided into blind (Group B, n = 35) and videolaryngoscope-guided (Group V, n = 35) Igel insertion. Oropharyngeal leak pressure (OLP), fiber-optic view score, time for device insertion, first attempt success, ease of insertion, ventilation score, maneuvers, and adverse events were assessed. RESULTS: OLP was significantly higher in group V at 1 and 10 minutes (24.80 ± 1.91 vs 21.71 ± 2.37; p < 0.001 and 32.60 ± 2.32 vs 30.68 ± 2.93; p = 0.006). The mean fiberoptic scoring (3.63 ± 0.49 vs 3.38 ± 0.49; p = 0.043), a fibreoptic score of grade 4 (24 vs 13; p = 0.012) and time-to-device insertion (25.6 ± 3.5 vs 21.7 ± 4.1; p < 0.001) was considerably higher in group V. First-attempt success (p = 0.630), ease of insertion of SAD (p = 0.540) and nasogastric tube (p = 1), ventilation score (p = 1), number of maneuvers required (p = 1), number of attempts (p = 0.592) and postoperative complications (p = 0.800) were comparable in the two groups. CONCLUSION: The videolaryngoscope-guided technique provided superior airway sealing and reduced malposition of Igel without an increase in adverse events compared to the blind technique. However, this was at the cost of increased time of device insertion. CLINICAL TRIAL REGISTRATION: www.ctri.nic.in identifier is CTRI/2022/10/046269.

Comparison of Hemodynamic and Recovery Profile Between Segmental Thoracic Spinal and General Anesthesia in Upper Abdominal and Breast Surgeries: A Systematic Review and Meta-Analysis.

Segmental thoracic spinal anesthesia (STSA) has been described primarily as case reports for performing upper abdominal and thoracic surgeries in significant respiratory comorbid patients. A few comparative studies have recently evaluated the technique as an advantageous alternative to general anesthesia (GA). However, there is no systematic evaluation and comparison of the techniques. The present systematic review evaluated the hemodynamic, comfort, and satisfaction of patients undergoing abdominal and thoracic surgeries under STSA and GA. PubMed, CENTRAL, Google Scholar Advanced, and citation tracking were performed to find suitable articles that compared STSA and GA. The primary objective-related data were hypotension and bradycardia. The secondary objective-related data in the context of postoperative nausea vomiting (PONV), pain, rescue analgesics, sedation requirement, satisfaction, and comfort were assessed. Meta-analysis was performed for dichotomous data on hypotension, bradycardia, and PONV; odds ratio (OR) and 95% confidence interval (CI) were reported. Data of 394 patients from six studies were evaluated. Patients undergoing upper abdominal and breast surgeries under STSA had significantly higher odds of hypotension (Fixed-Effect Model OR 12.23, 95% CI 2.81-53.28; I2 =0%, and the Random Effects Model OR 12.01, 95% CI 2.75-52.52; I2 =0%) and bradycardia (Fixed-Effect Model OR 10.95, 95% CI 2.94-40.74, I2 =0%, and the Random Effects Model OR 9.97, 95% CI 2.61-38.08; I2 =0%) but lower odds of PONV (Fixed-Effect Model OR 0.24, 95% CI 0.13-0.43; I2 =0%, and the Random Effects Model OR 0.24, 95% CI 0.13-0.45; I2 =0%). Most of the patients undergoing STSA were given intravenous sedation to overcome anxiety and discomfort. Overall, patient satisfaction was on par with GA. However, few surgeons were unenthusiastic about the technique while performing axillary clearances due to bothering twitches from cautery. STSA led to early post-anesthesia care unit (PACU) discharge and provided better pain control, lowering the need for rescue analgesics and opioid consumption in the first 24-hour postoperative period. STSA is associated with very high odds of hypotension and bradycardia as compared to GA. On the other hand, STSA demonstrated superior pain control, reduced opioid requirements, shorter PACU stays, and significantly reduced risk of PONV. Nevertheless, STSA patients mostly require sedation to make the patient comfortable.

Outcomes of dexmedetomidine as adjuvant drug in patients undergoing videolaparoscopic cholecystectomy: A randomized and prospective clinical trial.

OBJECTIVE: The repercussions of ischemia-reperfusion and inflammatory response to surgical injury may compromise the return of physiologic processes in video-laparoscopic surgeries. Dexmedetomidine, as an adjuvant drug in general anesthesia, alters the neuroinflammatory reaction, provides better clinical outcomes in the perioperative period, and may reduce the excessive use of chronic medication in patients with a history of addiction. This study evaluated the immunomodulatory potential of dexmedetomidine on perioperative organ function in video-laparoscopic cholecystectomy patients. METHODS: There were two groups: Sevoflurane and Dexmedetomidine A (26 patients) vs. Sevoflurane and Saline 0.9% B (26 patients). Three blood samples were collected three times: 1) before surgery, 2) 4-6h after surgery, and 3) 24h postoperatively. Inflammatory and endocrine mediators were protocolized for analysis. Finally, hemodynamic outcomes, quality upon awakening, pain, postoperative nausea and vomiting, and opioid use were compared between groups. RESULTS: We have demonstrated a reduction of Interleukin 6 six hours after surgery in group A: 34.10 (IQR 13.88-56.15) vs. 65.79 (IQR 23.13-104.97; p = 0.0425) in group B. Systolic blood pressure, diastolic blood pressure, and mean arterial pressure was attenuated in group A in their measurement intervals (p < 0.0001). There was a lower incidence of pain and opioid consumption in the first postoperative hour favoring this group (p < 0.0001). We noticed better quality upon awakening after the intervention when comparing the values of peripheral oxygen saturation and respiratory rate. CONCLUSIONS: Dexmedetomidine provided anti-inflammatory benefits and contributed to postoperative analgesia without the depressive side effects on the respiratory and cardiovascular systems commonly observed with opioids.
