Combination of etoricoxib and low-pressure pneumoperitoneum versus standard treatment for the management of pain after laparoscopic cholecystectomy: a randomized controlled trial

The Impact of Acupuncture on Pain Intensity, Nausea, and Vomiting for Laparoscopic Cholecystectomy: A Meta-analysis Study

BACKGROUND

Acupuncture may have some potential in pain relief after laparoscopic cholecystectomy, and this meta-analysis aims to explore the impact of acupuncture on pain intensity, nausea and vomiting for patients undergoing laparoscopic cholecystectomy.

METHODS

PubMed, EMbase, Web of science, EBSCO, Cochrane library databases, CNKI, VIP, and Wangfang were systematically searched, and we included randomized controlled trials (RCTs) assessing the effect of acupuncture on pain control for laparoscopic cholecystectomy.

RESULTS

Five RCTs and 366 patients were included in the meta-analysis. Overall, compared with control intervention for laparoscopic cholecystectomy, acupuncture was associated with significantly reduced pain scores at 6 hours [mean difference (MD)=-0.86; 95% CI=-1.37 to -0.34; P =0.001, 2 RCTs) and pain scores at 8 to 10 hours (MD=-0.71; 95% CI=-1.13 to -0.28; P =0.001, 2 RCTs), decreased incidence of nausea (odds ratio=0.10; 95% CI=0.03-0.34; P =0.0003, 3 RCTs), and vomiting (odds ratio=0.11; 95% CI=0.01-0.85; P =0.03, 3 RCTs), but demonstrated no obvious impact on pain scores at 12 to 24 hours (MD=-0.38; 95% CI=-1.02 to 0.27; P =0.25, 2 RCTs).

CONCLUSIONS

Acupuncture may be effective to reduce pain intensity, nausea, and vomiting for laparoscopic cholecystectomy.

Risks of serious adverse events with non-steroidal anti-inflammatory drugs in gastrointestinal surgery: A systematic review with meta-analysis and trial sequential analysis

BACKGROUND

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly recommended for perioperative opioid-sparing multimodal analgesic treatments. Concerns regarding the potential for serious adverse events (SAEs) associated with perioperative NSAID treatment are especially relevant following gastrointestinal surgery. We assessed the risks of SAEs with perioperative NSAID treatment in patients undergoing gastrointestinal surgery.

METHODS

We conducted a systematic review of randomised clinical trials assessing the harmful effects of NSAIDs versus placebo, usual care or no intervention in patients undergoing gastrointestinal surgery. The primary outcome was an incidence of SAEs. We systematically searched for eligible trials in five major databases up to January 2024. We performed risk of bias assessments to account for systematic errors, trial sequential analysis (TSA) to account for the risks of random errors, performed meta-analyses using R and used the Grading of Recommendations Assessment, Development and Evaluation framework to describe the certainty of evidence.

RESULTS

We included 22 trials enrolling 1622 patients for our primary analyses. Most trials were at high risk of bias. Meta-analyses (risk ratio 0.78; 95% confidence interval [CI] 0.51-1.19; I2 = 4%; p = .24; very low certainty of evidence) and TSA indicated a lack of information on the effects of NSAIDs compared to placebo on the risks of SAEs. Post-hoc beta-binomial regression sensitivity analyses including trials with zero events showed a reduction in SAEs with NSAIDs versus placebo (odds ratio 0.73; CI 0.54-0.99; p = .042).

CONCLUSION

In adult patients undergoing gastrointestinal surgery, there was insufficient information to draw firm conclusions on the effects of NSAIDs on SAEs. The certainty of the evidence was very low.

Low-pressure versus standard-pressure pneumoperitoneum in minimally invasive colorectal surgery: a systematic review, meta-analysis, and meta-regression analysis

BACKGROUND

We aimed to assess the efficacy and safety of low-pressure pneumoperitoneum (LPP) in minimally invasive colorectal surgery.

METHODS

A PRISMA-compliant systematic review/meta-analysis was conducted, searching PubMed, Scopus, Google Scholar, and clinicaltrials.gov for randomized-controlled trials assessing outcomes of LPP vs standard-pressure pneumoperitoneum (SPP) in colorectal surgery. Efficacy outcomes [pain score in post-anesthesia care unit (PACU), pain score postoperative day 1 (POD1), operative time, and hospital stay] and safety outcomes (blood loss and postoperative complications) were analyzed. Risk of bias2 tool assessed bias risk. The certainty of evidence was graded using GRADE.

RESULTS

Four studies included 537 patients (male 59.8%). LPP was undertaken in 280 (52.1%) patients and associated with lower pain scores in PACU [weighted mean difference: -1.06, 95% confidence interval (CI): -1.65 to -0.47, P = 0.004, I 2  = 0%] and POD1 (weighted mean difference: -0.49, 95% CI: -0.91 to -0.07, P = 0.024, I 2  = 0%). Meta-regression showed that age [standard error (SE): 0.036, P < 0.001], male sex (SE: 0.006, P < 0.001), and operative time (SE: 0.002, P = 0.027) were significantly associated with increased complications with LPP. In addition, 5.9%-14.5% of surgeons using LLP requested pressure increases to equal the SPP group. The grade of evidence was high for pain score in PACU and on POD1 postoperative complications and major complications, and blood loss, moderate for operative time, low for intraoperative complications, and very low for length of stay.

CONCLUSIONS

LPP was associated with lower pain scores in PACU and on POD1 with similar operative times, length of stay, and safety profile compared with SPP in colorectal surgery. Although LPP was not associated with increased complications, older patients, males, patients undergoing laparoscopic surgery, and those with longer operative times may be at risk of increased complications.

Low intra-abdominal pressure in laparoscopic surgery: a systematic review and meta-analysis

BACKGROUND

Guidelines do not provide clear recommendations with regard to the use of low intra-abdominal pressure (IAP) during laparoscopic surgery. The aim of this meta-analysis is to assess the influence of low versus standard IAP during laparoscopic surgery on the key-outcomes in perioperative medicine as defined by the StEP-COMPAC consensus group.

MATERIALS AND METHODS

We searched the Cochrane Library, PubMed, and EMBASE for randomized controlled trials comparing low IAP (<10 mmHg) with standard IAP (10 mmHg or higher) during laparoscopic surgery without time, language, or blinding restrictions. According to the PRISMA guidelines, two review authors independently identified trials and extracted data. Risk ratio (RR), and mean difference (MD), with 95% CIs were calculated using random-effects models with RevMan5. Main outcomes were based on StEP-COMPAC recommendations, and included postoperative complications, postoperative pain, postoperative nausea and vomiting (PONV) scores, and length of hospital stay.

RESULTS

Eighty-five studies in a wide range of laparoscopic procedures (7349 patients) were included in this meta-analysis. The available evidence indicates that the use of low IAP (<10 mmHg) leads to a lower incidence of mild (Clavien-Dindo grade 1-2) postoperative complications (RR=0.68, 95% CI: 0.53-0.86), lower pain scores (MD=-0.68, 95% CI: -0.82 to 0.54) and PONV incidence (RR=0.67, 95% CI: 0.51-0.88), and a reduced length of hospital stay (MD=-0.29, 95% CI: -0.46 to 0.11). Low IAP did not increase the risk of intraoperative complications (RR=1.15, 95% CI: 0.77-1.73).

CONCLUSIONS

Given the established safety and the reduced incidence of mild postoperative complications, lower pain scores, reduced incidence of PONV, and shorter length of stay, the available evidence supports a moderate to strong recommendation (1a level of evidence) in favor of low IAP during laparoscopic surgery.

Effect of Acupuncture on Postoperative Pain in Patients after Laparoscopic Cholecystectomy: A Randomized Clinical Trial

Objective

To evaluate the efficacy and safety of acupuncture compared to that of parecoxib sodium on postoperative pain (POP), postoperative nausea and vomiting (PONV), and the Bruggemann Comfort Scale (BCS) in patients following laparoscopic cholecystectomy (LC).

Methods

Eligible patients admitted to the hospital for LC were randomly allocated to either acupuncture or control groups in a 1 : 1 ratio. The subjects in the acupuncture group received acupuncture while those in the control group were injected by parecoxib sodium at their requests. The pain score, PONV score, and BCS were assessed at 0 h, 6 h, 9 h, and 12 h after operation. The primary outcome was the pain score. The secondary outcomes included the number of patients asking for parecoxib sodium from the two groups at 0-6 h and 6-12 h, PONV score, and BCS score.

Results

The pain score of the acupuncture group were lower in acupuncture than that in the control group at 6 h and 9 h after operation (P=0.002, P=0.008). However, no difference was found at 12 h. Besides, the number of patients administered parecoxib sodium in acupuncture group was less than that in the control group both at 0-6 h and 6-12 h after operation (P=0.019, P < 0.001). Similarly, there were significantly lower levels of PONV score and higher levels of BCS at 6 h after operation in the acupuncture group than in the control group. However, no difference was found at 9 h and 12 h.

Conclusion

Acupuncture can clinically improve the short-term treatment of postoperative pain after LC and reduce the request for extra analgesics; therefore, acupuncture might be a potential method as one of multimodal analgesia techniques to treat POP following LC.

Low-pressure versus standard-pressure pneumoperitoneum in laparoscopic cholecystectomy: a systematic review and meta-analysis of randomized controlled trials

INTRODUCTION

It has been previously demonstrated that the rise of intra-abdominal pressures and prolonged exposure to such pressures can produce changes in the cardiovascular and pulmonary dynamic which, though potentially well tolerated in the majority of healthy patients with adequate cardiopulmonary reserve, may be less well tolerated when cardiopulmonary reserve is poor. Nevertheless, theoretically lowering intra-abdominal pressure could reduce the impact of pneumoperitoneum on the blood circulation of intra-abdominal organs as well as cardiopulmonary function. However, the evidence remains weak, and as such, the debate remains unresolved. The aim of this systematic review and meta-analysis was to demonstrate the current knowledge around the effect of pneumoperitoneum at different pressures levels during laparoscopic cholecystectomy.

MATERIALS AND METHODS

This systematic review and meta-analysis were reported according to the recommendations of the 2020 updated Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) guidelines, and the Cochrane handbook for systematic reviews of interventions.

RESULTS

This systematic review and meta-analysis included 44 randomized controlled trials that compared different pressures of pneumoperitoneum in the setting of elective laparoscopic cholecystectomy. Length of hospital, conversion rate, and complications rate were not significantly different, whereas statistically significant differences were observed in post-operative pain and analgesic consumption. According to the GRADE criteria, overall quality of evidence was high for intra-operative bile spillage (critical outcome), overall complications (critical outcome), shoulder pain (critical outcome), and overall post-operative pain (critical outcome). Overall quality of evidence was moderate for conversion to open surgery (critical outcome), post-operative pain at 1 day (critical outcome), post-operative pain at 3 days (important outcome), and bleeding (critical outcome). Overall quality of evidence was low for operative time (important outcome), length of hospital stay (important outcome), post-operative pain at 12 h (critical outcome), and was very low for post-operative pain at 1 h (critical outcome), post-operative pain at 4 h (critical outcome), post-operative pain at 8 h (critical outcome), and post-operative pain at 2 days (critical outcome).

CONCLUSIONS

This review allowed us to draw conclusive results from the use of low-pressure pneumoperitoneum with an adequate quality of evidence.

Comparison of pharmacologic therapies alone versus operative techniques in combination with pharmacologic therapies for postoperative analgesia in patients undergoing laparoscopic cholecystectomy: A randomized controlled trial

BACKGROUND

Laparoscopic cholecystectomy (LC) causes moderate pain. Various operative analgesic techniques and pharmacologic treatments can reduce postoperative pain. This single-center, single-surgeon randomized controlled study aimed to assess the efficacy of combined operative analgesic techniques and pharmacologic analgesia in decreasing pain in patients undergoing LC.

MATERIALS AND METHODS

Fifty-nine patients scheduled for LC were assigned into two groups. In the pharmacologic analgesia (P) group (n = 29), patients were treated with pharmacologic intervention, including preoperative celecoxib (200 mg), intraoperative acetaminophen (1 g), and dexamethasone (8 mg). In the operative analgesic treatments with pharmacologic analgesia (OP) group (n = 30), patients were treated with both operative analgesic techniques and pharmacologic analgesia, including low-pressure pneumoperitoneum, intraperitoneal normal saline irrigation, and aspiration of intraperitoneal carbon dioxide. The area under the curve (AUC) of pain score for postoperative 24 h was assessed at 0, 2, 6, and 24 h post-operation. The analgesic requirements and sleep quality at postoperative day 1 were assessed.

RESULTS

The AUC/24 h of pain scores at rest and on cough were lower in the OP group (p < 0.001 and p = 0.001, respectively). The pain scores at rest were lower in the OP group at postoperative 2, 6, and 24 h (p = 0.001, p = 0.001, and p = 0.048, respectively). The pain scores on cough were lower in the OP group at postoperative 2 and 6 h (p = 0.004 and p = 0.008, respectively). Analgesic requirements were comparable. The sleep quality score at postoperative day 1 was higher in the OP group (56 ± 18 vs. 67 ± 15, absolute difference, 10; 95% confidence interval, 2 to 19; p = 0.017).

CONCLUSIONS

Combined operative analgesic therapies and pharmacologic analgesia compared to pharmacologic analgesia alone decreased pain scores and increased sleep quality in patients undergoing LC.

Does low dose of etoricoxib play pre-emptive analgesic effect in third molar surgery? A randomized clinical trial

Background

How to prevent pain after the extraction of impacted teeth is a serious challenge for all patients. The purpose of this clinical trial was to investigate whether pre-emptive low dose of etoricoxib can reduce postoperative pain in patients undergoing third molars surgery.

Methods

Patients were randomised to receive etoricoxib 60 mg or placebo 30 min before surgery. Post-operative pain was recorded using a visual analogue scale during 24 h within the post-operative period. The total dose of ibuprofen rescue intake was recorded. Kaplan–Meier curves and log-rank analyses were used to evaluate the proportion of patients without rescue analgesic.

Results

Scores for the post-operative pain in the etoricoxib group were significantly lower than those in the placebo group during first 12 h (p < 0.05). The number of patients without analgesic rescue medication was significantly lower in the etoricoxib group than in the placebo group. The average amount of rescue medication in the etoricoxib group (0.4 ± 0.9 dose) was lower than that in the placebo group (1.1 ± 0.9 doses, p = 0.004). Etoricoxib resulted in the long-term survival of patients without rescue analgesic (p < 0.001).

Conclusions

This study revealed that etoricoxib has a substantial pre-emptive analgesic effect, resulting in the reduced use of analgesics after third molar removal.

The Comparison of Postoperative Pain, Nausea, and Vomiting between Veress Needle Entry and Direct Trocar Entry Methods in Patients Undergoing Laparoscopic Cholecystectomy

BACKGROUND Postoperative pain, nausea, and vomiting are the most common side effects of laparoscopic cholecystectomy (LC). In the present study, we investigated the differences in postoperative pain, nausea, and vomiting between Veress needle and direct trocar entry methods among patients undergoing LC. METHODS 96 patients with gallstones were studied. They were randomly divided into two groups: the patients in the first group (n = 48) were insufflated 8.1 liters per minute CO2 gas by direct trocar port, and the patients in another group (n = 48) were insufflated 2.1 liters per minute CO2 gas by Veress needle. Pain intensity, nausea, and vomiting were assessed at 20 minutes, 4 hours, and 12 hours after the operations. RESULTS The duration of CO2 gas insufflation in Veress needle was 88.7 ± 10.7 seconds and indirect trocar was 16.6 ± 1.6 seconds. Visual analog scale (VAS) score significantly reduced in Veress needle compared with direct trocar (0.39 ± 0.98 vs. 1.68 ± 1.48) at 20 min after the operation, while there was no difference at 4 hours and 12 hours after the operation. The requirement and dose of pethidine injection were significantly lower in Veress needle than direct trocar. In addition, nausea and vomiting occurred in Veress needle less than direct trocar at 20 min, 4 hours, and 12 hours after LC. CONCLUSION Pain intensity just in the short term after LC in the group with CO2 gas insufflation in Veress needle was significantly less than the other group, while nausea and vomiting were significantly less during the whole follow-up periods in the group with CO2 gas insufflation in Veress needle.

The impact of intra-abdominal pressure on perioperative outcomes in laparoscopic cholecystectomy: a systematic review and network meta-analysis of randomized controlled trials

Background

Laparoscopic cholecystectomy involves using intra-abdominal pressure (IAP) to facilitate adequate surgical conditions. However, there is no consensus on optimal IAP levels to improve surgical outcomes. Therefore, we conducted a systematic literature review (SLR) to examine outcomes of low, standard, and high IAP among adults undergoing laparoscopic cholecystectomy.

Methods

An electronic database search was performed to identify randomized controlled trials (RCTs) that compared outcomes of low, standard, and high IAP among adults undergoing laparoscopic cholecystectomy. A Bayesian network meta-analysis (NMA) was used to conduct pairwise meta-analyses and indirect treatment comparisons of the levels of IAP assessed across trials.

Results

The SLR and NMA included 22 studies. Compared with standard IAP, on a scale of 0 (no pain at all) to 10 (worst imaginable pain), low IAP was associated with significantly lower overall pain scores at 24 h (mean difference [MD]: − 0.70; 95% credible interval [CrI]: − 1.26, − 0.13) and reduced risk of shoulder pain 24 h (odds ratio [OR] 0.24; 95% CrI 0.12, 0.48) and 72 h post-surgery (OR 0.22; 95% CrI 0.07, 0.65). Hospital stay was shorter with low IAP (MD: − 0.14 days; 95% CrI − 0.30, − 0.01). High IAP was not associated with a significant difference for these outcomes when compared with standard or low IAP. No significant differences were found between the IAP levels regarding need for conversion to open surgery; post-operative acute bleeding, pain at 72 h, nausea, and vomiting; and duration of surgery.

Conclusions

Our study of published trials indicates that using low, as opposed to standard, IAP during laparoscopic cholecystectomy may reduce patients’ post-operative pain, including shoulder pain, and length of hospital stay. Heterogeneity in the pooled estimates and high risk of bias of the included trials suggest the need for high-quality, adequately powered RCTs to confirm these findings.

Effect of postoperative Trendelenburg position on shoulder pain after gynecological laparoscopic procedures: a randomized clinical trial

BACKGROUND

Laparoscopic surgery has become a standard of care for many gynecological surgeries due to its lower morbidity, pain and cost compared to open techniques. Unfortunately, the use of carbon dioxide (CO2) to insufflate the abdomen is the main contributor to post-operative shoulder pain.

METHODS

We aim to assess the effect of postoperative Trendelenburg position on shoulder pain after gynecological laparoscopic procedures. We hypothesize that maintaining the patient in Trendelenburg for 24 h postoperatively will significantly decrease postoperative shoulder pain and analgesic consumption. After obtaining written informed consent, 108 patients were prospectively randomized into two groups. In the control group, patients underwent standard gynecologic laparoscopic procedures; then after passive deflation of the pneumoperitoneum at the end of the surgery, the patients were placed in supine head up position in the post anesthesia care unit (PACU) and received our institution's common postoperative care. Patients in the intervention group were subjected to the same maneuver but were positioned in a Trendelenburg position (20 °) once fully awake and cooperative in the PACU and retained this position for the first 24 h. Numerical rating scale (NRS) was used to assess shoulder pain and nausea upon patient arrival to the PACU, at 4, 6, 12 (primary outcome) and 24 h postoperatively. Time to first rescue pain medication, total rescue pain medications and overall satisfaction with pain control were recorded. 101 patients were included in the final data analysis.

RESULTS

Both groups were comparable in terms of baseline characteristics. NRS pain scores were significantly lower in the intervention group at 12 h compared to the control group (0 [0-1] versus 5 [1-4], p < 0.001), furthermore improvement in postoperative shoulder pain between time of arrival to PACU (time zero) and 12 h postoperatively was significantly higher in patients allocated to the experimental group compared to the control group. Pain scores were significantly lower in patients allocated to the experimental group versus the control group (0 [0-1] versus 5 [1-4], p < 0.001).

CONCLUSION

In conclusion, Trendelenburg position is an easy non-pharmacologic intervention that is beneficial in reducing postoperative shoulder pain following gynecologic laparoscopic surgery.

Comparison of Effectiveness of Etoricoxib and Diclofenac on Pain and Perioperative Sequelae After Surgical Avulsion of Mandibular Third Molars: A Randomized, Controlled, Clinical Trial

OBJECTIVE

The objective of this analysis was to compare the efficacy of etoricoxib and diclofenac in the management of perioperative sequelae following impacted mandibular third molar surgery.

MATERIALS AND METHODS

Ninety-seven patients who needed surgical avulsion of an impacted mandibular third molar were chosen for the study. All patients were randomly allocated to receive one of the following treatments, twice a day for 5 days after surgery: placebo (n=33), diclofenac (n=32), or etoricoxib (n=32). The primary outcome evaluated was postoperative pain, recorded by each patient and evaluated using the Visual Analogue Scale score. The secondary outcomes chosen were, compared with preoperative ones, changes in postoperative swelling and maximum mouth opening.

RESULTS

Compared with placebo, treatment with etoricoxib and diclofenac demonstrated an enhancement in the primary outcome. Furthermore, when compared with the other groups, patients who had undergone etoricoxib presented a significant median reduction in postoperative pain at 2 hours (P<0.001), 12 hours (P=0.025), and at 48 hours (P=0.018) after surgery. Moreover, the linear regression analysis showed that diclofenac and etoricoxib determined a significant influence on Visual Analogue Scale at 2, 6, 12, 24, 48 hours and at 10 days after surgery. There were no differences in swelling and maximum mouth opening values between groups.

DISCUSSION

This study demonstrated that both treatments were effective. However, treatment with etoricoxib showed a greater reduction in the incidence and severity of postoperative pain following third molar surgery compared with diclofenac and placebo.

The Influence of Etoricoxib on Pain Control for Laparoscopic Cholecystectomy: A Meta-analysis of Randomized Controlled Trials

INTRODUCTION

The efficacy of etoricoxib on pain control for laparoscopic cholecystectomy remains controversial. We conduct a systematic review and meta-analysis to explore the impact of etoricoxib on pain intensity after laparoscopic cholecystectomy.

MATERIALS AND METHODS

We searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through September 2018 for randomized controlled trials assessing the effect of etoricoxib versus placebo on pain management after laparoscopic cholecystectomy. This meta-analysis was performed using the random-effect model.

RESULTS

Four randomized controlled trials involving 351 patients are included in the meta-analysis. Overall, compared with control group for laparoscopic cholecystectomy, etoricoxib has no important impact on pain scores within 4 hours [mean difference (MD)=-1.48; 95% confidence interval (CI)=-3.54 to 0.58; P=0.16] and 8 hours (MD=-0.65; 95% CI=-1.43 to 0.12; P=0.10), but can significantly decrease pain intensity within 12 hours (MD=-1.16; 95% CI=-1.93 to -0.38; P=0.003) and 24 hours (MD=-1.10; 95% CI=-1.98 to -0.22; P=0.01), as well as postoperative analgesic consumption (standard MD=-1.21; 95% CI=-2.19 to -0.23; P=0.02), with no increase in nausea and vomiting (risk ratio=0.68; 95% CI=0.42-1.10; P=0.11), and headache (risk ratio=0.96; 95% CI=0.44-2.09; P=0.92).

CONCLUSIONS

Etoricoxib can substantially reduce pain intensity in patients with laparoscopic cholecystectomy.

Randomized controlled trial comparing the effects of usual gas release, active aspiration, and passive-valve release on abdominal distension in patients who have undergone laparoscopic cholecystectomy

INTRODUCTION

Residual, intra-abdominal CO₂ contributes to abdominal distension and pain after laparoscopic surgery. The study was designed to assess recovery after gas release in patients who have undergone laparoscopic cholecystectomy (LC).

METHODS

A total of 142 patients undergoing laparoscopic cholecystectomy were randomly divided into three groups: (i) group 1 (control group), gas release from the surgical wound without port release (n = 47); (ii) group 2, active gas aspiration via a subdiaphragmatic port (n = 48); and (iii) group 3, passive-valve release via a subdiaphragmatic port valve opening (n = 47). Abdominal distension and shoulder pain levels were assessed postoperatively.

RESULTS

The active aspiration group had significantly reduced postoperative abdominal distensions at 30 min, 4, and 24 h compared with the control group (50.0% vs 80.9%, 43.8% vs 76.6%, 33.3% vs 57.4%, respectively; P < 0.05). Similarly, the passive-valve release group had significantly reduced postoperative abdominal distensions at 4 and 24 h compared with the control group (51.1% vs 76.6%, 57.4% vs 36.2%; P < 0.05). Both intervention groups had significantly reduced postoperative shoulder pain at 4 and 24 h compared with the control group (P < 0.001). In addition, the postoperative ambulation times for the active aspiration group were significantly shorter than those for the control and passive-valve release groups (P < 0.001).

CONCLUSION

Releasing residual CO₂ from the intra-abdominal cavity at the end of laparoscopic cholecystectomy by either the active aspiration or passive-valve release technique is an effective way to reduce postoperative abdominal distension and shoulder pain.

The Effect of Exaggerated Lithotomy Position on Shoulder Pain after Laparoscopic Cholecystectomy

BACKGROUND

The exaggerated lithotomy position with the expertise of nurses can be successful solution for the patients who have the postoperative shoulder pain after laparoscopic cholecystectomy.

AIMS

This study aimed to determine the effect of applying an exaggerated lithotomy positions to patients who had laparoscopic cholecystectomy to relieve shoulder pain. The study was conducted on nonrandomized groups and made as a semiexperimental study with a pretest/post-test control group design. Design, Settings, and Subjects/Participants: The study was conducted on 102 patients who had elective laparoscopic cholecystectomy and agreed to participate in this study after they met the inclusion-exclusion criteria in the general surgery clinic of a training and research hospital in Istanbul between December 12, 2012, and June 30, 2013.

METHODS

The pain levels (10 minutes before and after positioning) and peripheral oxygen saturation (SPO₂) levels (1 minute, 5 minutes, and 10 minutes before and after positioning-total 6 times) of the patients were measured using a visual analog scale and pulse oximetry, respectively. The pain levels and the analgesic (pethidine hydrochloride and diclofenac sodium) usage of the patients in both the experimental and the control group were compared.

RESULTS

The exaggerated lithotomy position appreciably lowered the shoulder pain of the patients in the experimental group (t = 12.663; p = .000 < .001). It also increased peripheral saturation levels of the patients more rapidly compared with those in the control group receiving analgesics (t = 17.693; p = .000 < .005). In addition, it decreased the need to use additional analgesics and opioids (t = 2.14; p = .037).

CONCLUSIONS

In this study the exaggerated lithotomy position was found to be fast and effective for relieving shoulder pain after laparoscopic cholecystectomy, decreased the need to use additional analgesics and opioids, and, in conjunction with pain control, also contributed to improvements in respiratory functions.

Predictive Factors for a Long Hospital Stay in Patients Undergoing Laparoscopic Cholecystectomy

Background. Although the advantages of laparoscopic cholecystectomy (LC) over open cholecystectomy are immediately obvious and appreciated, several patients need a postoperative hospital stay of more than 24 hours. Thus, the predictive factors for this longer stay need to be investigated. The aim of this study was to identify the causes of a long hospital stay after LC. Methods. This is a retrospective cohort study with 500 successful elective LC patients being included in the analysis. Short hospital stay was defined as being discharged within 24 hours after the operation, whereas long hospital stay was defined as the need for a stay of more than 24 hours after the operation. Results. Using multivariable analysis, ten independent predictive factors were identified for a long hospital stay. These included patients with cirrhosis, patients with a history of previous acute cholecystitis, cholangitis, or pancreatitis, patients on anticoagulation with warfarin, patients with standard-pressure pneumoperitoneum, patients who had been given metoclopramide as an intraoperative antiemetic drug, patients who had been using abdominal drain, patients who had numeric rating scale for pain > 3, patients with an oral analgesia requirement > 2 doses, complications, and private ward admission. Conclusions. LC difficulties were important predictive factors for a long hospital stay, as well as medication and operative factors.
