A systematic review of interventions to facilitate ambulatory laparoscopic cholecystectomy

What is the impact of dexamethasone on postoperative pain in adults undergoing general anaesthesia for elective abdominal surgery: a systematic review and meta-analysis

Background

Previous meta-analysis of heterogeneous surgical cohorts demonstrated reduction in postoperative pain with perioperative intravenous dexamethasone, but none have addressed adults undergoing elective abdominal surgery. The aim of this study was to determine the impact of intravenous perioperative dexamethasone on postoperative pain in adults undergoing elective abdominal surgery under general anaesthesia.

Methods

This review was prospectively registered on the international prospective register of systematic reviews (CRD42020176202). Electronic databases Medical Analysis and Retrieval System Online (MEDLINE), Exerpta Medica Database (EMBASE), (CINAHL) Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science and trial registries were searched to January 28 2021 for randomised controlled trials, comparing dexamethasone to placebo or alternative antiemetic, that reported pain. The primary outcome was pain score, and secondary outcomes were time to first analgesia, opioid requirements and time to post-anaesthesia care unit (PACU) discharge.

Results

Fifty-two studies (5768 participants) were included in the meta-analysis. Pain scores ≤ 4 hour (h) were reduced in patients who received dexamethasone at rest (mean difference (MD), − 0.54, 95% confidence interval (CI) − 0.72 to − 0.35, I² = 81%) and on movement (MD − 0.42, 95% CI − 0.62 to − 0.22, I² = 35). In the dexamethasone group, 4–24 h pain scores were less at rest (MD − 0.31, 95% CI − 0.47 to − 0.14, I² = 96) and on movement (MD − 0.26, 95% CI − 0.39 to − 0.13, I² = 29) and pain scores ≥ 24 h were reduced at rest (MD − 0.38, 95% CI − 0.52 to − 0.24, I² = 88) and on movement (MD − 0.38, 95% CI − 0.65 to − 0.11, I² = 71). Time to first analgesia (minutes) was increased (MD 22.92, 95% CI 11.09 to 34.75, I² = 98), opioid requirements (mg oral morphine) decreased (MD − 6.66, 95% CI − 9.38 to − 3.93, I² = 88) and no difference in time to PACU discharge (MD − 3.82, 95% CI − 10.87 to 3.23, I² = 59%).

Conclusions

Patients receiving dexamethasone had reduced pain scores, postoperative opioid requirements and longer time to first analgesia. Dexamethasone is an effective analgesic adjunct for patients undergoing abdominal surgery.

Quality of recovery assessment of day case and multiday stay patients undergoing elective laparoscopic cholecystectomy

Objectives

Many laparoscopic cholecystectomy operations are performed with at least overnight admission. Current research shows that laparoscopic cholecystectomy is safe and feasible to do as a day case. Patient centred outcomes are less well understood.

Material and Methods

Elective laparoscopic cholecystectomy patients at a single metropolitan hospital in Melbourne, Australia were surveyed 24 hours after surgery using the 15-question Quality of Recovery (QoR-15) survey. A comparison was made between day case surgeries and multi-day surgeries.

Results

One hundred and eight patients were recruited consisting of 34 day case and 74 multi-day patients. Patient groups did not differ in terms of age, sex or postoperative morbidity. The multi-day group had a higher proportion of comorbid patients (p-value = 0.03). There was no significant dif- ference in overall QoR-15 score between the two groups, although there was an observed trend towards a higher score in the day case group (132.0 vs 127.9, p= 0.147). QoR-15 individual question results showed that day cases rated significantly better for sleep quality and for less feelings of anxiety or worry. The differences narrowed when comparing patient groups as they were booked (intention-to-treat). There were no identified sub-groups that had a significantly higher score if admitted multi-day.

Conclusion

Quality of recovery following day case laparoscopic cholecystectomy is just as good, if not better, than multi-day cases. Laparoscopic cholecystectomy as a day case is both safe and economically superior to multi-day management. This gives further weight to current recommendations suggesting that the majority of laparoscopic cholecystectomy operations could be performed as day cases.

Reduced Laparoscopic Intra-abdominal Pressure During Laparoscopic Cholecystectomy and Its Effect on Post-operative Pain: a Double-Blinded Randomised Control Trial

BACKGROUND

Laparoscopic surgery is regarded as the gold standard for the surgical management of cholelithiasis. To improve post-operative pain, low-pressure laparoscopic cholecystectomies (LPLC) have been trialed. A recent systematic review found that LPLC reduced pain; however, many of the randomised control trials were at a high risk of bias and the overall quality of evidence was low.

METHODS

One hundred patients undergoing elective laparoscopic cholecystectomy were randomised to a LPLC (8 mmHg) or a standard pressure laparoscopic cholecystectomy (12 mmHg) (SPLC) with surgeons and anaesthetists blinded to the pressure. Pressures were increased if vision was compromised. Primary outcomes were post-operative pain and analgesia requirements at 4-6 h and 24 h.

RESULTS

Intra-operative visibility was significantly reduced in LPLC (p<0.01) resulting in a higher number of operations requiring the pressure to be increased (29% vs 8%, p=0.010); however, there were no differences in length of operation or post-operative outcomes. Pain scores were comparable at all time points across all pressures; however, recovery room fentanyl requirement was more than four times higher when comparing 8 to 12 mmHg (12.5mcg vs 60mcg, p=0.047). Nausea and vomiting was also higher when comparing these pressures (0/36 vs 7/60, p=0.033). Interestingly, when surgeons estimated the operating pressure, they were correct in only 69% of cases.

CONCLUSION

Although pain scores were similar, there was a significant reduction in fentanyl requirement and nausea/vomiting in LPLC. Although LPLC compromised intra-operative visibility requiring increased pressure in some cases, there was no difference in complications, suggesting LPLC is safe and beneficial to attempt in all patients.

Safety of ambulatory laparoscopic cholecystectomy in the elderly

BACKGROUND

This study aims to retrospectively analyse the safety of ambulatory laparoscopic cholecystectomy (ALC) and identify risk factors for delayed discharge after ALC in the elderly.

METHODS

Consecutive patients who were scheduled to undergo ALC were assigned to the elderly group (age ≥ 65 years) or the non-elderly group. The primary outcome was postoperative discharge within 24 h (D24). Secondary outcomes were perioperative mortality, reasons for delayed discharge (psychosocial reasons (DP), complications (DC), drainage (DD) and conversion to open surgery (DCO)), intraoperative data and readmission within 30 days after discharge (readmission). Differences were statistically significant when P < 0.05.

RESULTS

There were 7657 patients assigned to the elderly group (n = 1143) or the non-elderly group (n = 6514). The differences between elderly patients and non-elderly patients in the operation time (51.0 (37.0-70.0) versus 50.0 (35.0-65.0) min), blood loss (10.0 (5.0-10.0) versus 5.0 (5.0-10.0) mL), D24 (75.5% versus 81.7%) and DD (7.8% versus 3.2%) were statistically significant (P < 0.05, respectively). The differences between elderly patients and non-elderly patients in DP (8.2% versus 6.7%), DC (7.8% versus 7.9%), DCO (0.7% versus 0.5%) and readmission (0.5% versus 0.4%) were not statistically significant (P > 0.05, respectively). Independent risk factors for delayed discharge after ALC in the elderly were male sex, octogenarian status, prolonged operation time, arrhythmia, type 2 diabetes mellitus, a previous operation in the upper abdomen, acute inflammation of gallbladder and a gallbladder wall thicker than 3 mm (P < 0.05, respectively).

CONCLUSION

ALC in the elderly is feasible and safe.

Systematic review and meta-analysis of factors which reduce the length of stay associated with elective laparoscopic cholecystectomy

BACKGROUND

Laparoscopic cholecystectomy is a safe ambulatory procedure in appropriately selected patients; however, day case rates remain low. The objective of this systematic review and meta-analysis was to identify interventions which are effective in reducing the length of stay (LOS) or improving the day case rate for elective laparoscopic cholecystectomy.

METHODS

Comparative English-language studies describing perioperative interventions applicable to elective laparoscopic cholecystectomy in adult patients and their impact on LOS or day case rate were included.

RESULTS

Quantitative data were available for meta-analysis from 80 studies of 10,615 patients. There were an additional 17 studies included for systematic review. The included studies evaluated 14 peri-operative interventions. Implementation of a formal day case care pathway was associated with a significantly shorter LOS (MD = 24.9 h, 95% CI, 18.7-31.2, p < 0.001) and an improved day case rate (OR = 3.5; 95% CI, 1.5-8.1, p = 0.005). Use of non-steroidal anti-inflammatories, dexamethasone and prophylactic antibiotics were associated with smaller reductions in LOS.

CONCLUSION

Care pathway implementation demonstrated a significant impact on LOS and day case rates. A limited effect was noted for smaller independent interventions. In order to achieve optimal day case targets, a greater understanding of the effective elements of a care pathway and local barriers to implementation is required.

Day-only elective cholecystectomy: early experience and barriers to implementation in Australia

BACKGROUND

Day-only laparoscopic cholecystectomy (DOLC) has been shown to be safe and feasible yet has not been widely implemented in Australia. This study explores the introduction of routine DOLC to Westmead Hospital, and highlights the barriers to its implementation.

METHODS

Routine day-only cholecystectomy protocol was introduced at Westmead Hospital in 2014. A retrospective review of patients who underwent elective laparoscopic cholecystectomy during a 12-month period in 2014 was compared to a 12-month period in 2018, to examine the changes in practice after implementation of a unit protocol. Data were collected on patient demographics, admission category, outcomes and re-presentations.

RESULTS

A total of 282 patients were included in the study, of these 169 were booked as day procedures, with 124 (73%) successfully discharged on the same day. There was a significant increase in the proportion of patients booked as day-only from 2014 to 2018 (48% versus 73%, P < 0.001). Day-only failure rates (unplanned overnight admissions), readmissions and complication rates were comparable between the two periods. The most common reason for unplanned overnight admissions were due to intraoperative findings (n = 28/45).

CONCLUSION

Routine DOLC can be adopted in Australian hospitals without compromise to patient safety. Unplanned overnight admission is predominantly due to unexpected surgical pathology and can be reduced by protocols for the use of drains and planned outpatient endoscopic retrograde cholangiopancreatography. Unplanned outpatient review can be minimized by optimizing both intra- and post-operative pain management. Individual surgeon and anaesthetist preferences remain an obstacle to a standardized protocol in the Australian setting.

One-lung ventilation to treat hepatic dome lesion - a further step towards minimally invasive surgery: a case report

Background

Although liver resection is still the best treatment for primary or metastatic hepatic lesions, a conventional surgical approach may be challenging in patients with a history of previous abdominal surgery. We present a case of a 58-year-old white man with paracaval, subdiaphragmatic, recurrent hepatocellular carcinoma; he had a history of multiple abdominal surgeries.

Methods

In select patients, percutaneous ultrasound-guided thermal ablation is a valid non-surgical alternative due to its safety, efficacy, and good tolerability. Hepatic lesions located in the posterosuperior segments, however, can be difficult to reach via a percutaneous approach.

Result

For these cases, one-lung left-sided ventilation may be particularly helpful in blocking the right hemidiaphragm and improving the acoustic window to the liver.

Conclusion

We present a case of paracaval, subdiaphragmatic, recurrent hepatocellular carcinoma in which the tumor was only reachable after one-lung left-sided ventilation that was successfully treated by percutaneous ultrasound-guided microwave ablation.

Perioperative factors that contribute to postoperative pain and/or nausea and vomiting in ambulatory laparoscopic surgery

INTRODUCTION

Both postoperative pain and postoperative nausea and vomiting are major factors that determine the time and quality of recovery in laparoscopic surgery.

OBJECTIVE

To determine the perioperative factors that contribute to the appearance of postoperative pain and postoperative nausea and vomiting in outpatient laparoscopic surgery.

MATERIAL AND METHODS

A prospective study was conducted on a cohort of 297 patients undergoing laparoscopic ambulatory surgery. A record was made of preoperative factors (usual medication, anaesthetic risk, etc.), intraoperative (surgical and anaesthetic times, drugs, CO₂ pressure, etc.), and postoperative factors (major and minor complications, recovery times, etc.). As dependent variables, the postoperative symptoms considered were, nausea, vomiting, and/or postoperative pain.

RESULTS

Considering as a combined variable the occurrence of níusea, vomiting or moderate/severe pain (4 or more points on a visual analogue scale), one or more of these symptoms occurred in 58.7% of the patients (95% CI: 52.8-64.4). Using a logistic regression, the variables associated with the appearance of symptoms were: female gender (OR: 3.4), waiting time over 45minutes prior to surgery (OR: 4.9) and no anti-emetic prophylaxis (OR: 12.2).

CONCLUSIONS

In patients undergoing ambulatory laparoscopic surgery, one in 4had postoperative nausea and vomiting, and approximately half of moderate-intensity pain before discharge. Considering the overall the occurrence of pain and/or postoperative níusea and vomiting, these symptoms affect more than half of the patients being operated on, and are more frequent in women and in those who have to wait to access the operating room.

Anesthetic therapy for acute pain relief after laparoscopic cholecystectomy: systematic review

Inappropriate therapy of postoperative pain in laparoscopic cholecystectomy may lead to late mobilization, patient dissatisfaction, delayed hospital discharge, and chronic pain development. Our objective was to identify the best therapeutic strategy available to the anesthesiologist for the acute postoperative pain of patients submitted to elective laparoscopic cholecystectomy. This is a systematic review that included 36 complete articles indexed in the Medline, Scopus, Web of Science and LILACS databases, with a five-year time cut (2012 to 2016), resulting from controlled and randomized studies that were submitted to qualitative analysis. In a proposal for multimodal analgesia, it is important to consider the contraindications, adverse effects, dose and optimal timing of interventions. Non-opioid drugs, such as non-steroidal anti-inflammatory drugs (NSAIDs)/cyclooxygenase-2 (COX-2) inhibitors, gabapentin/pregabalin, N-methyl-D-aspartate (NMDA) receptor antagonists, and others. Opioids may be used at low doses associated with multimodal therapy or are restricted to cases where non-opioid multimodal analgesia is insufficient. We conclude that there is no consensus as to the best analgesic strategy to be implemented in the acute postoperative pain of laparoscopic cholecystectomy, which requires its applicability in an individualized way, based on the scientific evidence found in the literature. As contribution to medical learning and practice, we point out the theoretical enrichment of the analgesic drug options available for the therapy of postoperative pain in patients submitted to elective laparoscopic cholecystectomy, and alert the team to consider the adverse effects of the interventions implemented.

A Narrative Review of the Evidence on the Efficacy of Dexamethasone on Postoperative Analgesic Consumption

OBJECTIVES

The effect of dexamethasone on analgesic consumption has not been adequately studied. The aim of this review was to investigate recent literature regarding the possible effect of dexamethasone on postoperative analgesic consumption.

METHODS

Critical review of randomized trials and prospective consecutive studies investigating the postoperative analgesic effect of dexamethasone was performed. Only studies published during 2006 to 2015 were included.

RESULTS

Forty-one studies met the inclusion criteria; 33 in adults and 8 in children (9 in general surgery, 8 in gynecologic/breast surgery, 8 in orthopedic/spinal surgery, 8 in head/neck surgery, 7 in children's tonsillectomy, and 1 in children's orchiopexy). Literature review demonstrated that dexamethasone can decrease analgesic requirements in patients undergoing laparoscopic cholecystectomies, laparoscopic gynecologic and breast surgery; whereas there is no consensus regarding orthopedic procedures, with positive evidence mostly regarding spinal surgeries. The efficacy of dexamethasone during head and neck surgery is not conclusive; however, its use before thyroid surgery may be beneficial. In children a beneficial impact of dexamethasone administration was revealed on posttonsillectomy reduction of analgesic needs. Studies on other kinds of operations in children are lacking.

CONCLUSIONS

Dexamethasone administered at a dose of 8 mg before surgical incision may be beneficial in laparoscopic cholecystectomies, thyroid, laparoscopic gynecologic and breast surgery, and tonsillectomies in children. Dexamethasone's potential impact on reducing postoperative analgesic requirements should be investigated in more detail in a systematic manner, to support its use in other kinds of operations.

Increasing success in outpatient laparoscopic cholecystectomy by an optimal clinical pathway

BACKGROUND

The objective of this study was to evaluate the impact of more convincing and reassuring remarks from the surgeon in the preoperative consult associated with a dedicated outpatient facility to increase our rate of success in outpatient laparoscopic cholecystectomy.

METHODS

A one-centre prospective clinical study was conducted between February 2013 and May 2015. During the first time period (February 2013-March 2014), patients were hospitalized in conventional care unit and given the possibility to choose an outpatient procedure. In the second phase (April 2014-May 2015), the patients were held in a dedicated outpatient facility. Outpatient success rate was evaluated using Chung's discharge score 6 h after surgery.

RESULTS

Eighty patients were included (30 in a traditional setting, 50 in an optimal clinical pathway). Both groups were comparable for mean age, American Society of Anesthesiologists score and mean operative time (P = 0.36, P = 1 and P = 0.09, respectively). Success in outpatient surgery was significantly higher in the optimal clinical pathway group (73.3% versus 96%, P = 0.005). The only criteria which was significantly improved in Chung score was perambulation (P = 0.001). There was no significant difference between the two groups for post-operative complications (P = 0.28) or readmission (P = 1).

CONCLUSION

Optimal clinical pathway (more convincing and reassuring remarks in the preoperative consult and a dedicated outpatient facility) is the key to increase success in outpatient laparoscopic cholecystectomy.

Randomized controlled study of intraincisional infiltration versus intraperitoneal instillation of standardized dose of ropivacaine 0.2% in post-laparoscopic cholecystectomy pain: Do we really need high doses of local anesthetics-time to rethink!

BACKGROUND

Earlier studies done to compare the efficacy of use of local anesthetics at intraperitoneal location versus intraincisional use had utilized equal amount of drugs at the two locations, usually 10-20 ml. Using this large amount of drug in the small space of intraincisional location as compared to similar amount of drug in large intraperitoneal space created an inadvertent bias in favor of patients receiving the drug intraincisionally so these patients naturally experienced less pain.

AIMS AND OBJECTIVES

To conduct a randomized, triple-blind, placebo-controlled study by standardizing dose of local anesthetic, to compare the effectiveness of intraperitoneal against intraincisional use of ropivacaine 0.2% for post-laparoscopic cholecystectomy pain relief.

MATERIALS AND METHODS

294 patients underwent elective 4-port laparoscopic cholecystectomy. Patients were triple blindly randomized. All patients received ~ 23 ml of solution, of which 20 ml was given intraperitoneally (1 ml/cm; 16 ml along right hemi-dome and 4 ml in gall bladder fossa) and ~ 3 ml intraincisionally (1 ml/cm of length of incision). Solution was either normal saline or drug (0.2% ropivacaine) depending on the group [controls (n = 86), intraperitoneal group (n = 100), and intraincisional group (n = 108)]. 5 different pain scales were used for assessment of overall pain. Pain scores were assessed at 5 points of time.

RESULTS

Patients in intraincisional group showed significantly less overall pain and rescue analgesia requirement (p < 0.05). Intraincisional group showed significantly less overall pain (p < 0.05) as compared to intraperitoneal group; however, use of rescue analgesia was comparable in the two groups (p > 0.05); and shoulder pain was significantly less in intraperitoneal group (p < 0.05).

CONCLUSION

The intraincisional use of injection ropivacaine at its minimum concentration of 0.2% in minimal doses of 1 ml/cm at the end of procedure provides significantly more post-operative analgesia as compared to intraperitoneal group and controls. However, for controlling shoulder pain, the use of intraperitoneal ropivacaine is desirable.

[First experience with outpatient laparoscopic cholecystectomy in Tunisia]

Introduction

Laparoscopic cholecystectomy is the gold standard treatment for symptomatic gallstones. There is some debate as to whether it should be performed in outpatient surgery or in one-day surgery to improve patient safety. This study aimed to evaluate the impact of laparoscopic cholecystectomy performed in outpatient surgery versus one-day surgery on standards such as mortality, serious adverse events and quality of life.

Methods

We conducted a cross-sectional descriptive study in the Department of General Surgery at the Habib Thameur Hospital over the period May 2009-February 2010. We here report 67 cases of symptomatic vesical lithiasis treated with outpatient laparoscopic cholecystectomy (OLC). ASA III and IV patients, diabetic patients treated with sulfonamides or insulin, severely obese patients, patients over 65 years of age and under 18 years of age, patients with a history of major abdominal surgery, patients with suspected lithiasis of the common bile duct, acute cholecystitis or pancreatitis were excluded from the study. Patients had to reside within 50 km of the hospital and be accompanied by an adult to undergo OLC.

Results

Seventeen patients were included and then excluded from our study because of the perioperative detection of signs of acute cholecystitis or difficulties in dissection leading to subhepatic drainage using Redon catheter at the end of the intervention. Finally, our study included 50 patients, 7 men and 43 women; the average age was 48 years. Surgery was based on the most common procedures. After leaving the recovery room, patients were conducted in the outpatient sector where they received a liquid diet. The patients were examined before 7 o'clock in the evening and discharge was established on the basis of the possibility of establishing an oral analgesic treatment, patients tolerance to liquid diet, the lack of urinary disorder, patients acceptance for discharge and analgesic and anti-inflammatory treatment if needed. Thirty-nine patients (78%) were discharged from hospital and 11 were kept in hospital. Patients > 45 years of age, anesthesia duration > 70 minutes and post operative fatigue were identified as risk factors for unsuccessful discharge. No readmission was observed. Discharged patients were satisfied with the therapeutic protocol, resulting in excellent and good outcome in the majority of cases (94%).

Conclusion

Outpatient laparoscopic cholecystectomy seems to be as safe as day surgery laparoscopic cholecystectomy having low rate of complications and of hospital readmissions in some selected patients and lower surgery costs.

Effect of Oral Clonidine on Shoulder Tip Pain and Hemodynamic Response After Laparoscopic Cholecystectomy: A Randomized Double Blind Study

Background

Shoulder tip pain is a common problem after laparoscopic cholecystectomy. There are a few clinical trial studies on the effect of clonidine on post laparoscopic shoulder pain (PLSP). This study aimed at evaluating the effect of oral clonidine on PLSP in semi-sitting position and post-operative hemodynamic response of patients undergoing LC surgery.

Methods

This randomized controlled clinical trial was conducted on 60 patients, who were candidates for elective laparoscopic cholecystectomy surgery under general anesthesia, and were randomly allocated to clonidine and placebo groups. Patients in the clonidine group received 0.2 mg oral, 90 minutes prior to induction. Patients in the placebo group received vitamin C tablets during the same time. Postoperative pain intensity was assessed, using a visual analog scale at the emergence from anesthesia, 4 and 8 hours after the operation by an anesthetist, who was blinded to the patient group. Mean arterial blood pressure and heart rate were recorded before clonidine administration and in post-operative period.

Results

The mean age was 36.85 ± 10.93 years and the mean Body Mass was 26.34 ± 3.46 kg/m². Two groups were not comparable with respect to occurrence of PLSP (P = 0.739). There was a significant difference in intensity of PLSP between the 2 groups at emergence from anesthesia (P = 0.012), 4 and 8 hours after the operation (P = 0.001) between 2 groups. The clonidine group showed a larger reduction of pain intensity at these phases. The result of independent t test indicated significant differences in the MABP value between the 2 groups at the time of emergence from anesthesia (P = 0.031). The clonidine group demonstrated a lower MABP level at this time.

Conclusions

Oral clonidine is not effective in preventing the PLSP. However, it alleviates PLSP intensity in the patient under LC procedure on the first post-operative hours.

Corticosteroids or Not for Postoperative Nausea: A Double-Blinded Randomized Study

BACKGROUND

Postoperative nausea and vomiting (PONV) is common after general anaesthesia, and corticosteroids are used in many protocols for enhanced recovery after surgery (ERAS). However, surgical techniques are developing, and ERAS protocols need to be reevaluated from time to time.

PATIENTS AND METHOD

In this study, we compared the effects of oral vs. parenteral corticosteroid administration on postoperative nausea. Elective Roux-y-gastric bypass (RYGB) patients were randomly assigned to either 8 mg betamethasone orally (n = 50) or parentally (n = 25) or as controls (n = 25), in a double-blind design. PONV risk factors were noted. All patients had the same anaesthetic technique. Data were collected at baseline, on arrival to the recovery room (RR) and at five more time points during the first 24 h. Nausea and tiredness were patient assessed using visual analogue scales; rescue drug consumption was recorded.

RESULTS

Operation time was 30-40 min. Neither demographics nor risk factors for nausea differed between groups. Neither peak values for nor total amount of nausea differed between groups. The number of supplemental injections was the same for all groups.

COMMENTS

In a setting of modern laparoscopic RYGB, the value of betamethasone in preventing PONV seems to be limited. ERAS protocols may need re-evaluation.

AMBULATORY LAPAROSCOPIC CHOLECYSTECTOMY IS SAFE AND COST-EFFECTIVE: a Brazilian single center experience

ABSTRACT Background - Laparoscopic cholecystectomy is the treatment of choice for gallstone disease, and has been perfomed as an outpatient surgery in many Institutions over the last few years. Objective - This is a retrospective study of a single center in Brazil, that aims to analyze the outcomes of 200 cases of ambulatory laparoscopic cholecystectomy performed by the same Hepato-Pancreato-Biliary team, evaluating the safety and cost-effectiveness of the method. Methods - Two hundred consecutive patients who underwent elective laparoscopic cholecystectomy were retrospectively analyzed; some of them underwent additional procedures, as liver biopsies and abdominal hernias repair. Results - From a total of 200 cases, the outpatient surgery protocol could not be carried out in 22 (11%). Twenty one (95.5%) patients remained hospitalized for 1 day and 1 (4.5%) patient remained hospitalized for 2 days. From the 178 patients who underwent ambulatory laparoscopic cholecystectomy, 3 (1.7 %) patients returned to the emergency room before the review appointment. Hospital cost was on average 35% lower for the ambulatory group. Conclusion - With appropriate selection criteria, ambulatory laparoscopic cholecystectomy is feasible, safe and effective; readmission rate is low, as well as complications related to the method. Cost savings and patient satisfaction support its adoption. Other studies are necessary to recommend this procedure as standard practice in Brazil.

Ambulatory laparoscopic cholecystectomy: A single center experience

AIM

To evaluate the demographic and clinical parameters affecting the outcomes of ambulatory laparoscopic cholecystectomy (ALC) in terms of pain, nausea, anxiety level, and satisfaction of patients in a tertiary health center.

MATERIALS AND METHODS

ALC was offered to 60 patients who met the inclusion criteria. Follow-up (questioning for postoperative pain or discomfort, nausea or vomiting, overall satisfaction) was done by telephone contact on the same day at 22:00 p.m. and the first day after surgery at 8: 00 a.m. and by clinical examination one week after operation. STAI I and II data were used for proceeding to the level of anxiety of patients before and/or after the operation.

RESULTS

Sixty consecutive patients, with a mean age of 40.6 ± 8.1 years underwent ALC. Fifty-five (92%) patients could be sent to their homes on the same day but five patients could not be sent due to anxiety, pain, or social indications. Nausea was reported in four (6.7%) cases and not associated with any demographic or clinical features of patients. On the other hand, pain has been reported in 28 (46.7%) cases, and obesity and shorter duration of gallbladder disease were associated with the increased pain perception (P = 0.009 and 0.004, respectively). Preopereative anxiety level was significantly higher among patients who could not complete the ALC procedure (P = 0.018).

CONCLUSION

Correct management of these possible adverse effects results in the increased satisfaction of patients and may encourage this more cost-effective and safe method of laparoscopic cholecystectomy.

Post-Operative Pain Management in Patients Undergoing Robotic Urological Surgery

Robotic urological surgery is being increasingly performed worldwide. The main focus currently is on the operative technique but post operative patient care is an essential part of the process to make this technique safe and successful. We present a review on multiple analgesic techniques available to prevent and treat pain specifically caused after by urological robotic surgery; this article will explain the mechanism of pain pathways involved in laparoscopic procedures and review current evidence pertaining to systemic and regional analgesia methods.

Day surgery versus overnight stay laparoscopic cholecystectomy: A systematic review and meta-analysis

BACKGROUND

Laparoscopic cholecystectomies are being increasingly performed as a day surgery procedure.

AIM

To systematically assess the safety and efficacy of laparoscopic cholecystectomy as a day surgery procedure compared to overnight stay.

METHODS

Randomized controlled trials and clinical controlled trials involving day surgery laparoscopic cholecystectomy were included in a systematic literature search. Two authors independently assessed the studies for inclusion and extracted the data. A meta-analysis was conducted to estimate the safety and feasibility of day surgery compared to overnight stay laparoscopic cholecystectomy.

RESULTS

Twelve studies were selected for our meta-analysis. The meta-analysis showed that there was no significant difference between the two groups on morbidity (P=0.65). The mean in-hospital admission and readmission rates were 13.1% and 2.4% in the day surgery group, respectively. The two groups had similar prolonged hospitalization (P=0.27), readmission rate (P=0.58) and consultation rate (P=0.73). In addition, there was no significant difference in the visual analogue scale score, postoperative nausea and vomiting scale, time to return to activity and work between the two groups (P>0.05).

CONCLUSIONS

Currently available evidence demonstrates that laparoscopic cholecystectomy can be performed safely in selected patients as a day surgery procedure, though further studies are needed.

Laparoscopic cholecystectomy: consensus conference-based guidelines

INTRODUCTION

Laparoscopic cholecystectomy (LC) is the gold standard technique for gallbladder diseases in both acute and elective surgery. Nevertheless, reports from national surveys still seem to represent some doubts regarding its diffusion. There is neither a wide consensus on its indications nor on its possible related morbidity. On the other hand, more than 25 years have passed since the introduction of LC, and we have all witnessed the exponential growth of knowledge, skill and technology that has followed it. In 1995, the EAES published its consensus statement on laparoscopic cholecystectomy in which seven main questions were answered, according to the available evidence. During the following 20 years, there have been several additional guidelines on LC, mainly focused on some particular aspect, such as emergency or concomitant biliary tract surgery.

METHODS

In 2012, several Italian surgical societies decided to revisit the clinical recommendations for the role of laparoscopy in the treatment of gallbladder diseases in adults, to update and supplement the existing guidelines with recommendations that reflect what is known and what constitutes good practice concerning LC.

Outpatient laparoscopic cholecystectomy and pain control: a series of 100 cases

INTRODUCTION

We present our experience of 100 consecutive cases that underwent ambulatory cholecystectomy using a standard protocol of anesthesia and surgery.

PATIENTS AND METHOD

Prospective study of 100 consecutive patients assessed in the surgery outpatient clinic in Torrevieja Hospital (September 2008-september 2009). Both anesthetic and surgical techniques were protocolized, standardized. The protocol included the use of intraperitoneal and parietal anesthesia.

RESULTS

One hundred patients were included. Average age was 53 years and average surgical time was 29±12 min. Day-case surgery rate was 96%. Postoperative pain (VAS scale) was less than 4 in all cases. Six patients complained of nausea that eased with the administration of ev metoclopramide. Average length of stay in the day-case surgery unit was 7.4h (maximum 9.6, minimum 7). Morbidity and mortality rates were 0%. No re-admission was registered and conversion rate was 0%. Postoperative follow-up was 100%. A total of 97% of the cases were fully satisfied with the procedure.

CONCLUSION

Ambulatory laparoscopic cholecystectomy is a feasible and safe technique. Postoperative pain has classically been the reason to not perform day-case surgery, but we achieved an excellent control by the combined use of local anesthetics and warm intraperitoneal saline solution.

Double-blind randomized sham controlled trial of intraperitoneal bupivacaine during emergency laparoscopic cholecystectomy

BACKGROUND

Intraperitoneal local anesthesia (IPLA) during elective laparoscopic cholecystectomy (el-LC) decreases post-operative pain. None of the studies have explored the efficacy of IPLA at emergency laparoscopic cholecystectomy (em-LC). A longer operative duration, the greater frequency of washing, and the inflammation associated with cholecystitis or pancreatitis are a few reasons why it cannot be assumed that a benefit in pain scores will be seen in em-LC with IPLA. This study was undertaken to assess the efficacy of IPLA in patients undergoing em-LC.

METHODS

Double-blind randomized sham controlled trial was conducted of 41 consecutive subjects undergoing em-LC. IPLA was delivered by a combination of injection to the diaphragmatic and topical wash over the liver and gallbladder with bupivacaine or saline. The primary outcome was visual analogue scale pain scores until discharge. Secondary outcomes included pain scores in theatre recovery and analgesic consumption.

RESULTS

One patient had a procedure converted to open and was excluded. There was no significant difference in pain scores in the ward or theatre recovery. Analgesic use, respiratory rate, oxygen saturation, duration to ambulation, eating, satisfaction scores, and time to discharge were comparable between the two groups.

CONCLUSIONS

IPLA during em-LC does not influence postoperative pain. Other modalities of analgesia should be explored for decreasing the interval between diagnosis of acute admission and em-LC.
