The effects of laparoscopic guided transversus abdominis plane (TAP) block in sleeve gastrectomy procedure: a randomized single blinded placebo controlled trial

A randomized controlled trial on the effectiveness of laparoscopic-guided transversus abdominis plane block in patients undergoing laparoscopic IPOM plus.

Ventral hernia repairs, particularly laparoscopic ventral hernia repair (LVHR), have become common procedures among general surgeons worldwide. Despite the benefits of LVHR, acute postoperative pain remains a significant concern. Transversus abdominis plane (TAP) blocks have been employed to alleviate postoperative pain in various laparoscopic procedures. This study aimed to assess the effectiveness of laparoscopic-guided TAP block in laparoscopic IPOM plus and its impact on postoperative pain and analgesic requirements. A randomized controlled trial was conducted at a tertiary care center in India involving 72 patients undergoing laparoscopic IPOM plus. Patients were randomized into two groups: Group I received laparoscopic-guided TAP block, while Group II received standard general anesthesia without TAP block. Pain scores were assessed at 6, 12, and 24h postoperatively using the numerical rating scale. Postoperative analgesic requirements were also recorded. Group I demonstrated significantly lower pain scores at 6 and 24h postoperatively compared to Group II. The need for additional analgesics was significantly lower in Group I (13.8%) compared to Group II (72.2%). There were no significant differences in age, BMI, duration of surgery, or other demographic characteristics between the two groups. The findings of this randomized controlled trial demonstrate the effectiveness of laparoscopic-guided TAP blocks in reducing postoperative pain and analgesic requirements after laparoscopic IPOM plus.

Laparoscopic versus Ultrasound-Guided Transversus Abdominis Plane Block for Postoperative Analgesia Management after Radical Prostatectomy: Results from a Single Center Study.

(1) Background: Regional anesthesia, achieved through nerve blocks, has gained widespread acceptance as an effective pain management approach. This research aimed to evaluate the efficacy of laparoscopic (LAP) transversus abdominis plane (TAP) block in patients undergoing laparoscopic radical prostatectomy. (2) Methods: From January 2023 to July 2023, 60 consecutive patients undergoing minimally invasive radical prostatectomy were selected. Patients were split into two groups receiving ultrasound-guided (US) or laparoscopic-guided TAP block. The primary outcome was a pain score expressed by a 0-10 visual analog scale (VAS) during the first 72 h after surgery. (3) Results: Both LAP-TAP and US-TAP block groups were associated with lower pain scores postoperatively. No statistically significant differences were observed between the two groups in surgery time, blood loss, time to ambulation, length of stay, and pain after surgery (all p > 0.2). In the LAP-TAP block group, the overall operating room time was significantly shorter than in the US-TAP block group (140 vs. 152 min, p = 0.04). (4) Conclusions: The laparoscopic approach, compared to the US-TAP block, was equally safe and not inferior in reducing analgesic drug use postoperatively. Moreover, the intraoperative LAP-TAP block seems to be a time-sparing procedure that could be recommended when patient-controlled analgesia cannot be delivered.

Randomized single blind trial to compare the short term post-operative outcome and cost analysis of laparoscopic versus ultrasound guided transversus abdominis plane block in patients undergoing bariatric surgery.

Laparoscopic Bariatric surgery despite being minimally invasive can cause moderate to severe pain in the immediate postoperative period. Adequate pain management remains a major challenge. Transversus Abdominis Plane (TAP) block is a regional anesthesia technique which blocks the sensory nerve supply of anterior-lateral abdominal wall. Primary: evaluate Laparoscopic versus ultrasound (USG)-guided TAP block on immediate post-operative analgesia after undergoing laparoscopic bariatric surgery. Secondary: compare cost effectiveness of Laparoscopic versus ultrasound-guided TAP block after undergoing bariatric surgery. Randomized Single blind study undertaken after sample size was calculated by (N) = 2(Zα + Z1-β)2σ2/δ2 which proposed 60 patients in each group. Block randomization was done after excluding redo/revision surgeries and patients were alloted Group I: Laparoscopic-guided TAP block & Group II: USG-guided TAP block. In both groups, Bilaterally, 20ml (0.25%) bupivacaine was injected immediately after completion of bariatric surgery. SPSS v23 (IBM Corp.) was used for analysis. Group I (N = 61 53F/8M) & Group II (N = 60 42F/18M) were demographically comparable. Group I (3.58 ± 0.67) had significantly lower procedure time compared to Group II (12.47 ± 1.61) (p-Value < 0.001). First rescue analgesia was administered at 7.07 ± 2.61h in Group I vs 7.21 ± 2.39h in Group II (p-Value 0.659). In first 24h rescue analgesic dose requirement in Group I was 1.29 ± 0.53 vs 1.39 ± 0.50 in Group II (p-Value 0.487). VAS scores during rest and movement till 24h post-operative were statistically similar. Procedural cost was more in group II. Laparoscopic-guided TAP block is a safe and cost-effective approach for postoperative pain management after bariatric surgery and provides similar comparable analgesic effect as the USG-TAP block. Laparoscopic TAP is a surgeon delivered, easy to administer and significantly less time-consuming procedure which is feasible even when an ultrasound machine is not available.

METHODS: A consecutive series of patients who underwent RALP were administered laparoscopic guided transversus abdominis plane block by the surgeon. A validated numeric pain rating scale was used to record their pain during their postoperative hospital stay. Also, the morphine milligram equivalents (MME) for pain medications were calculated. RESULTS: A total of 61 patients were included in the analysis, 57 patients were discharged within 24 hours and 4 patients were discharged the following day. The mean pain score prior to discharge (24 hr) was 3.64 ± 1.81 (range 1-8). The MME for postoperative day 1 was 13.7 ± 11.03 (range 0-49) and 10.91 ± 8.77 (range 0-25) for postoperative day 2. There were no block related complications. CONCLUSIONS: The surgeon administered laparoscopic TAP block is a safe pain management tool. Studies compared laparoscopic guided TAP block with ultrasound-guided TAP block and reported no discernible differences in the efficacy of pain management following general surgical procedures. Direct visualization of the administration site minimizes complications such as iatrogenic visceral injury by the needle or administration of the local anesthetic in the wrong plane. In addition, the surgeon-administered block also potentially reduces the additional time taken to set up an ultrasound guided TAP block which requires an anesthesiologist and an ultrasound machine.

Surgeon administered transversus abdominis plane block: anatomic principles and technique.

The Transversus Abdominis Plane (TAP) block is a regional abdominal wall block that has been effectively used as an adjunct to alleviate postoperative pain. The ultrasound-guided TAP (USTAP) administered by anesthesiologists is the gold standard and has been effective for surgeries involving abdominal wall incisions. Recently, the TAP block has been administered by surgeons with the help of direct visualization during minimally invasive surgery. The surgeon-administered or laparoscopic-guided TAP block has been compared to the USTAP with no discernible difference in patient outcomes. Also, directly visualizing the injection in the surgeon-administered block can offset complications such as visceral injury and block failure (injectate in the wrong plane). This review explores the literature's surgeon-administered TAP blocks for minimally invasive surgery in the literature. In addition, the prerequisite anatomy of the anterolateral abdominal wall, various approaches, and other factors that influence the efficacy of the block are described to increase awareness of this analgesic tool among surgeons and achieve better postoperative pain management.

Efficacy and Cost-Effectiveness of Laparoscopic Transversus Abdominis Plane (TAP) Block in Laparoscopic Cholecystectomy: A Comparison With the Non-TAP Group.

Postoperative pain caused by laparoscopic cholecystectomy can be controlled by different methods. The study aimed to observe the efficacy of laparoscopic transversus abdominis plane (TAP) block in laparoscopic cholecystectomy and to analyze the cost-effectiveness of the procedure in comparison to the non-TAP method. In this double-blinded randomized clinical trial, the subjects who had come for cholecystectomy were randomly divided into two groups (n = 43 in each group). Group Areceived laparoscopy-guided subcostal TAP block bilaterally (0.25% bupivacaine, 20 ml each) along with parenteral analgesics (100 mg tramadol injection in 100 ml normal saline IV) SOSas rescue analgesia, and group Breceived parenteral analgesics (injection paracetamol 1 gm IV) eight hourly and injection tramadol 100 mg in 100 ml normal saline IV SOS as rescue analgesia. A bulge was visualized by the surgeon through a laparoscope as a signature view for confirming the placement of local anesthetic in TAP. Based on the Visual Analog Scale (VAS) for assessment of postoperative pain and the Numeric Rating Scale (NRS) for assessment of pain at 30 minutes, four hours, eight hours, 12 hours, and 24 hours postoperatively, patients of both groups were assessed. According to the VAS, the pain assessment was better in the TAP block group at 30 minutes post-surgery than in the non-TAP group. As a primary outcome, 37% of TAP block group cases were recovered without any rescue analgesia. VASscore revealed a significant difference in postoperative nausea and vomiting (PONV) among the TAP block and non-TAP groups. PONV at four hours, eight hours, and 12 hoursshowed significantly lesser incidences in the TAP group as compared to the non-TAP group (p-value: 0.015, 0.028, and 0.055, respectively). The cost-effectiveness of the TAP block method is 20 times lesser than the non-TAP method. Thus, a laparoscopic-guided TAP block could offer better postoperative analgesia at a low cost with a similar advantage to a USG-guided TAP block.

Does laparoscopic-guided transversus abdominis plane block have an effect on postoperative pain and recovery after sleeve gastrectomy?

Postoperative pain management is thought to have an effect on patient comfort, morbidity, and mortality after bariatric surgery. Local anesthetic agents are frequently used for this purpose. Local anesthetics can be used in many different ways. In this study, we aimed to investigate the effect of transversus abdominis plane (TAP) block on postoperative pain by laparoscopic method. A prospective randomized clinical trial was performed. While TAP block was applied to one group with bupivacaine, no action was taken for the other group. Postoperative analgesia was given to both patient groups with the "patient-controlled analgesia (PCA)" device. Demographic, operational, and postoperative clinical and pain data of the patients were recorded. TAP block and non-TAP block groups consisted of 30 patients each. Visual analog scale (VAS) scores of the patients at 6, 12, and 24 hours were lower in the TAP group compared to the non-TAP group (p=0.015, 0.018, 0.04, respectively). According to the PCA device data, the analgesic requirement was lower in the TAP group at 6, 12, and 24 hours (p <0.001). Rescue analgesia was required more in the non-TAP group (p=0.04). There was no statistically significant difference between the two groups in terms of gas discharge time (p=0.102), stool discharge occurred earlier in the TAP group (p=0.02). Oral intake times (p=0.554) and length of stay hospital (p=0.551) were similar. Laparoscopic TAP block using bupivacaine can be safely administered in morbidly obese patients and reduces postoperative analgesic requirements. Thus, side effects that may develop secondary to the use of analgesics are avoided.

Efficacy of laparoscopic transversus abdominis plane block on postoperative pain management and surgery side effects in laparoscopic bariatric surgeries.

Transversus abdominis plane (TAP) block is a new option for reducing postoperative pain. This study investigated the effects of laparoscopic TAP block on postoperative adverse events and analgesia and antiemetics requirements after bariatric surgery. In this randomized clinical trial study, patients were randomly divided into control (N = 20) or TAP block (N = 20) groups. In the TAP block group, the block was performed under direct laparoscopic guidance after surgery and before the removal of trocars. Fifteen patients (75%) versus four patients (20%) received opioids within the first 6h in the control and TAP groups, respectively (p-value < 0.001). The cumulative amount of opioids consumed in the 24 and 48h after surgery was lower in the TAP group (p-value < 0.001). The visual analog scale (VAS) regarding general and wound-specific pain was significantly lower in the TAP group compared to the control group at 6 and 24h both at rest and in movement. However, there was no significant difference at 48h postoperatively. The percentages of patients having postoperative nausea and vomiting (PONV), pruritus, and resumption of bowel movement were not significantly different between the two groups at any time (6, 24, and 48h) postoperatively. Laparoscopic-guided TAP block is a pragmatic, applicable, and minimally invasive regional technique and can be part of effective postoperative pain management in morbidly obese patients undergoing bariatric surgery. Applying it laparoscopically without the need for ultrasound is also useful and effective.

Efficacy of laparoscopic guided transversus abdominis plane block in post operative analgesia requirement in elective laparoscopic cholecystectomy

Background: Minimal invasive surgery has many advantages. In order to maintain and control pain, one of the most effective technique is Transversus abdominis plane (TAP) block technique. Aim of the study was to demonstrate the efficacy of laparoscopic guided transversus abdominis plane block in post-operative analgesia requirement in elective laparoscopic cholecystectomy.Methods: It was a hospital based prospective interventional study. Sample size was calculated at 0.05 α error and 80% study power assuming mean difference of VAS score between TAP block +/A group and TAP block- /B group is 1 and standard deviation of VAS score 1.3 among patients undergoing elective laparoscopic cholecystectomy.Results: A total of 60 patients were enrolled in this study. The mean age of group A was 48.56 years and for group B was 43.53 years. In group A 80% patients were females and for group B 83.3% patients were females. There was significant difference in VAS score at immediate post operation, at 1 hour, at 6 hours, at 18 hours and at 24 hours as p value was &lt;0.0001 for all these groups. The mean VAS score was recorded less in group A at all the time duration compared to group B.Conclusions: With advantages like maximum safety, efficacy, potential for lower visceral injury risk and shorter operational time and other numerous advantages (decreased analgesic requirements, etc.) laparoscopic-guided TAP block counts as an ideal abdominal field block in the patients.

Laparoscopic versus ultrasound-guided visualization of transversus abdominis plane blocks

BackgroundUltrasound-guided (US) transversus abdominis plane (TAP) block is commonly utilized as part of a multi-modal approach for postoperative pain management. This study seeks to determine whether laparoscopic-guided TAP blocks are as effective as US-guided TAP blocks among pediatric patients. MethodIn this prospective, randomized controlled trial, pediatric patients undergoing laparoscopic procedures were randomly assigned to one of two treatment arms: US-guided TAP block (US-arm) or laparoscopic-guided TAP block (LAP-arm). Primary outcome was PACU pain scores. Secondary outcomes included PACU opioid consumption, block completion time and block accuracy. ResultsTwenty-five patients were enrolled in each arm. In the LAP-arm, 59% of blocks were in the transversus abdominis plane compared to 74% of TAP blocks in the US-arm (p = 0.18). Blocks were completed faster in the LAP-arm (2.1 ± 1.9 vs. 7.9 ± 3.4 min, p<0.001). The average highest PACU pain score was 3.4 ± 3.1 for the LAP-arm and 4.3 ± 3.8 for the US-arm (p = 0.37). Overall PACU pain scores and opioid consumption were similar between the groups (1.2 ± 1.3 vs. 1.6 ± 1.6, p = 0.24; 2.2 ± 5.8 vs. 0.9 ± 1.4MME, p = 0.26). ConclusionLaparoscopic TAP blocks have equivalent efficacy in post-operative pain scores, narcotic use, and tissue plane accuracy as compared to US-guided TAP blocks. They are also completed faster and may result in less operating room and general anesthetic time for the pediatric patient.

Laparoscopic Transversus Abdominis Plane Block in Minimally Invasive Gynecologic Surgery

Study Objective To describe an evidence-based technique for performing laparoscopic guided Transversus Abdominis Plane (TAP) block at time of minimally invasive gynecologic surgery. Design Narrated video demonstrating surgical technique Setting The patient is placed in dorsal lithotomy position then prepped and draped in sterile fashion. After establishment of pneumoperitoneum and prior to additional trocar placement, the laparoscopic guided TAP block is performed in order to decrease perioperative pain, postoperative opioid use, time to return of bowel function, and time to discharge. Patients or Participants N/A Interventions After identification of anatomic landmarks, 7-8cc of local anesthetic is injected in 6-7 lateral locations extending from the anterior superior iliac spine to the costal margin. Our local anesthetic includes 20cc liposomal bupivacaine, combined with 30cc 0.5% bupivacaine and 30cc injectable saline for 80cc total. To locate the correct plane, the needle is inserted through the abdominal wall under laparoscopic visualization until it can be seen tenting the peritoneum. After retracting the needle slightly using tactile feedback, the local anesthetic is injected between the transversus abdominis muscle and the internal oblique muscle. A gentle bulging of the tissue, called Doyle's bulge, should be noted laparoscopically. After completion of bilateral TAP block, we proceed with the scheduled surgery. Measurements and Main Results N/A Conclusion Benefits of perioperative TAP block include decreased opioid use, quicker discharge, and faster return of bowel function at time of laparoscopic hysterectomy. Laparoscopic TAP block has demonstrated superiority over ultrasound guided approach in a randomized controlled trial. Lastly, Liposomal bupivacaine has improved benefit when compared to plain bupivacaine when used for TAP block.

Analgesic effect of postoperative laparoscopic-guided transversus abdominis plane (TAP) block, associated with preoperative port-site infiltration, within an enhanced recovery after surgery protocol in one-anastomosis gastric bypass: a randomized clinical trial.

The use of ultrasonography to assist needle placement during transverse abdominal plane (TAP) technique has provided direct visualization of surround anatomical musculature and facial planes. However, the increased girth in patients undergoing bariatric surgery is challenging to visualize via ultrasonography which may lead to poor postoperative analgesia. The aim of the study is to investigate whether the addition of postoperative laparoscopic-guided TAP block as part of a multimodal analgesic regimen within the ERAS protocol compared to no block provides better postoperative analgesia in patients undergoing one-anastomosis gastric bypass surgery. A prospective clinical trial was performed. Patients were randomized into two groups: patients undergoing postoperative laparoscopic-guided TAP (TAP-lap) and patients not receiving TAP-lap (Control). Multimodal analgesia included preoperative port-site infiltration with Bupivacaine 0.25% in both groups and systemic Acetaminophen. Pain quantification as measured by visual analogic scale (VAS) was assessed at 6 and 24h after surgery, and 24-h postoperative opioid consumption. One hundred and forty patients were included, 70 in each group. The mean operation time was 78.5 ± 14.4min in TAP-lap and 75.9 ± 15.6min in Control (NS). The mean postoperative pain, as measured by VAS, 6h after surgery was 23.1 ± 11.3mm in TAP-lap and 41.8 ± 16.2mm in Control (p = 0.001). 24h after surgery was 16.6 ± 11.4mm in TAP-lap and 35.4 ± 12.7mm in Control (p = 0.001). Morphine rescues were necessary in 14.2% in Control and 2.8% in TAP-lap (p = 0.035). Laparoscopic-guided TAP block as part of a multimodal analgesia regimen can reduce postoperative pain and opioid consumption, without increasing operative time.

Laparoscopic-guided transversus abdominis plane block following laparoscopic sleeve gastrectomy is associated with an earlier return to activity: a study of 271 patients.

The morbidly obese (MO) patient presents a unique challenge to pain control in the postoperative period due to associated comorbidities and the amplified impact of opiates. In order to reduce potential complications associated with narcotic use in the MO patient, multimodal analgesia has been advocated. In this study, we examined the effect of laparoscopic-guided transversus abdominis plane block (LG TAP) for further optimizing multimodal pain control. This is a retrospective analysis of a prospectively collected database of 140 consecutive patients undergoing LSG without TAP block (pre-TAP group) compared to 131 patients undergoing LSG with LGTAP (TAP group). All operations were performed laparoscopically utilizing uniform clinical pathways. Baseline characteristics for both groups were comparable. Both groups received standardized anesthesia. Outcomes included time to postoperative ambulation, pain scores, PCA volume, length of hospital stay, utilization of oral opiate medications, and return to activity (RTA). Pre-TAP versus TAP groups were comparable, mean age 42years (p = 0.99), women 81.4% versus 87.8% (p = 0.148), mean BMI (kg/m2) 46 versus 45 (p = 0.394). Most patients ambulated within 2h after arrival to the floor (87.9% vs. 76.3%, p = 0.013). On postoperative day (POD) 1, mean reported pain score (0-10) was 4.50 vs. 5.06 (p = 0.063) and a mean PCA morphine used for 24h was 26.3mL versus 26mL, p = 0.35. Mean days of postoperative opiate medication were 2.19 versus 1.24 (p < 0.001). Return to activity was 2.81 versus 2.08days (p < 0.001). When controlled for age, BMI, OR time, PCA volume used, and average pain score, TAP block was an independent predictor of earlier return to activities (p < 0.001). LGTAP block following LSG is an additional valuable modality of pain control in the perioperative period. Our study shows that TAP block is associated with an earlier RTA and decreased opiate use in patients undergoing LSG.

Efficacy of laparoscopic-guided transversus abdominis plane block for patients undergoing robotic-assisted gynaecologic surgery: A randomised control trial.

Background and Aims:Transverse abdominis plane (TAP) block has been used regularly as part of multimodal analgesia for caesarean sections and other lower abdominal surgeries. Adequate postoperative analgesia provided with regional blocks allows faster postoperative recovery and better patient satisfaction. In our study, we are comparing the analgesic efficacy of laparoscopic-guided TAP block with port infiltration using a local anaesthetic in patients undergoing gynaecologic robotic surgeries.Methods:After obtaining approval from the hospital ethics committee, Central Trial Registry of India (CTRI) clearance and written informed consent from patients, this prospective double-blinded randomised control trial was conducted on patients undergoing robotic-assisted gynaecologic surgery under general anaesthesia. Group B patients received bilateral TAP block under direct laparoscopic vision with 15 ml of 0.1% ropivacaine on each side and Group C patients received routine port site infiltration with 30 ml of 0.1% ropivacaine. Postoperative pain score was measured till 24 hours, need for rescue analgesics, complications associated were noted. Independent two sample 't' test, Mann Whitney u test, Chi-square and Fisher's exact test were used for statistical analysis.Results:Pain score was significantly lower in Group B patients up to 24h (P < 0.001). The use of rescue analgesic was also significantly less in group B compared to Group C (P < 0.001). No adverse events were noted in both groups.Conclusion:Laparoscopic-guided TAP block is effective and superior to port site infiltration in providing postoperative analgesia in patients undergoing robotic-assisted gynaecologic surgery.

Laparoscopic-guided transversus abdominis plane block versus trocar site local anesthetic infiltration in gynecologic laparoscopy

BackgroundRelieving postoperative pain and prompt resumption of physical activity are of the utmost importance for the patients and surgeons. Infiltration of local anesthetic is frequently used methods of pain control postoperatively. Laparoscopically delivered transversus abdominis plane block is a new modification of ultrasound-guided transversus abdominis plane block.This study was conducted to compare the efficacy of laparoscopic-guided transversus abdominis plane block with trocar site local anesthetic infiltration for pain control after gynecologic laparoscopy.ResultsNo statistically significant difference between the two groups in mean visual analogue scale at 1, 18, and 24 h (P = 0.34, P = 0.41, and P = 0.61, respectively), while the mean visual analogue scale was significantly lower in the laparoscopic-guided transversus abdominis plane block group than in the trocar site local anesthetic infiltration group at 3, 6, and 12 h (P = 0.049, P = 0.011, and P = 0.042, respectively). No statistically significant difference was observed in the cumulative narcotics consumed at 3 h (P = 0.52); however, women with transversus abdominis plane block have consumed significantly less amount of narcotics than women with trocar site infiltration at 6, 12, and 24 h (P = 0.04, P = 0.038, and P = 0.031 respectively). Patient satisfaction was significantly higher in the laparoscopic-guided transversus abdominis plane block group (P = 0.035).ConclusionLaparoscopic-guided transversus abdominis plane block is more effective in reduction of both pain scores in the early postoperative period and the cumulative narcotics consumption than trocar site local anesthetic infiltration in gynecologic laparoscopy.Trial registrationClinical Trials.gov NCT02973451

Laparoscopic-Guided Transversus Abdominis Plane (TAP) Block as Part of Multimodal Analgesia in Laparoscopic Roux-en-Y Gastric Bypass Within an Enhanced Recovery After Surgery (ERAS) Program: a Prospective Randomized Clinical Trial.

Despite the ultrasound guidance of transversus abdominis plane (TAP) blocks has allowed greater precision of needle placement in the desired tissue plane, visualization of the abdominal wall muscles can be hindered by morbid obesity and could lead to failed regional anesthesia. The aim of this study was to assess the feasibility and effect of laparoscopic-guided TAP block in patients undergoing Roux-en-Y gastric bypass and to compare it with port-site infiltration. A prospective randomized clinical trial was performed. Patients were randomized into two groups: patients undergoing laparoscopic-guided TAP (TAP-lap) and patients undergoing port-site infiltration (PSI). Pain quantification as measured by visual analogic scale (VAS) and morphine needs during the first 24h were evaluated. One hundred and forty patients were included, 70 in each group. The mean operation time was 83.3 + 15.6min in TAP-lap and 80.5 + 14.4min in PSI (NS). The mean postoperative pain, as measured by VAS, 24h after surgery was 16.8+ 11.2mm in PSI and 10 + 8.1mm in TAP-lap (p = 0.001). Morphine rescues were necessary in 13.2% in PSI and 2.9% in TAP-lap (p = 0.026). The mean hospital stay was 2.1 + 1.2days in TAP-lap and 2.9 + 1.3days in PSI (p = 0.019). Hospital discharge during the first 48h after surgery was possible in 52.9% of the patients in PSI and 71% in TAP-lap (OR 4.75; 95% CI 2.1-10.8; p = 0.029). Laparoscopic-guided TAP block can reduce postoperative pain, opioid needs, and hospital stay, when compared with port-site infiltration with the same anesthetic drug, without increasing operation time.

Efficacy of laparoscopic transversus abdominis plane block for elective laparoscopic cholecystectomy in elderly patients

Transversus abdominis plane (TAP) block technique seems to offer one of the most efficient methods for a local pain control. Our aim is to demonstrate the effectiveness and safety of TAP block for post-operative pain control under laparoscopic vision in elderly patients during laparoscopic cholecystectomy. The patients aged more than 65 years old, who had cholecystectomy due to symptomatic cholelithiasis, were retrospectively evaluated. The patients that were operated under general anesthesia + laparoscopic TAP block and those who were operated only under only general anesthesia were compared according to their’ age and gender, comorbidities, American Society of Anesthesiologists scores, visual analog scale (VAS) for pain and length of stay in the hospital. Median (±interquartile range) values of post-operative 24th-hour-VAS for pain was found consecutively 2 (±1-3) in TAP block + group and 3 (±2-5) in TAP block - group. The median post-operative 24th-hour-VAS value in overall patients was three. Patients’ VAS values were higher in the TAP block – group with a statistically significant difference (p = 0.001). Furthermore, no statistically significant difference was found for other parameters in two groups. The laparoscopic-guided TAP block can easily be performed and has potential for lower visceral injury risk and shorter operational time. Efficacy, safety and other advantages (analgesic requirements, etc.) make it an ideal abdominal field block in elderly patients.
