Background: The use of regional local anesthetics or opioids during laparoscopic cholecystectomy (LC), in combination with general anesthesia, has been investigated in several interventional studies. Methods: We studied a total of 240 (n = 60, each) patients who were undergoing LC, and they received local infiltration and intraperitoneal instillation with normal saline or 0.25% levobupivacaine 60 ml. Group R (S) received infiltration of normal saline 20 ml before incision and at the end of surgery and then 40 ml intraperitoneal instillation after removal of the gall bladder under remifentanil-based anesthesia. Group R (L) received 0.25% levobupivacaine instead of normal saline in the same method like group R (S). Group S (S) received the same method as group R (S) under sevoflurane based anesthesia in place of remifentanil. Group S (L) received 0.25% levobupivacaine instead of normal saline with the same method as group S (S). Pain was assessed on a visual analog scale at 1, 6, 12 and 24 hours after operation. Results: The pain intensity of Group R (L) was significantly lower than that of group R (S), and the the incisional pain of group S (L) was significantly lower than that of group S (S) in the first six hours. The time delay to first operative analgesics in group R (S) and group S (S) was significantly shorter than that of group R (L) and group S (L). Conclusions: Infiltration and instillation of levobupivacaine reduced the postoperative pain and remifentanil did not increase the pain severity and opioid requirement when performing the LC.

Background: Laparoscopic cholecystectomy (LC) is a noninvasive surgery, but postoperative pain is a major problem. Studies have indicated that erector spinae plane block (ESPB) has an analgesic effect after LC. We aimed to compare the efficacy of different ESPB anesthetic concentrations in pain control in patients with LC. Methods: This retrospective study included patients aged 20 to 75 years scheduled for LC with the American Society of Anesthesiologists physical status classification I or II. ESPB was administered using 0.375% bupivacaine in group 1 and 0.25% in group 2. Both groups received general anesthesia. Postoperative tramadol consumption and pain scores were compared and intraoperative and postoperative fentanyl requirements in the postanesthesia care unit (PACU) were measured. Results: Eighty-five patients were included in this analysis. Tramadol consumption in the first 12 hours, second 12 hours, and total 24 hours was similar between groups (p>0.05). The differences between postoperative numeric rating scale (NRS) scores at rest did not differ significantly. The postoperative NRS scores upon bodily movement were not statistically different between the two groups, except at 12 hours. The mean intraoperative and postoperative fentanyl requirements in the PACU were similar. The difference in the requirement for rescue analgesics was not statistically significant (p=0.788). Conclusion: Ultrasound-guided ESPB performed with different bupivacaine concentrations was effective in both groups for LC analgesia, with similar opioid consumption. A lower concentration of local anesthetic can be helpful for the safety of regional anesthesia and is recommended for the analgesic effect of ESPB in LC.

There are many variations and unclear definitions of the appropriate timing of laparoscopic cholecystectomy (LC) after endoscopic retrograde cholangiopancreatography (ERCP), and there is still a lack of consistency about the appropriate timing. Inappropriate timing can be associated with serious comorbidity and can affect the patients. This meta-analysis was conducted to assess the operative outcomes and morbidity to provide a benefit to the patients based on the best timing of LC after ERCP. Randomized controlled trials (RCTs) and retrospective studies were identified from the PubMed and Scopus databases from inception to July 2021. A meta-analysis was performed to estimate the treatment effects on operative outcomes and morbidity. Four RCTs and four retrospective studies met our inclusion criteria. A meta-analysis indicated that patients who received LC after ERCP on the same day or within 72 hours had about 0.354 days shorter length of hospital stay with a shorter operative time of about 0.111-1.835 minutes and a lower risk of complications around 37%-73%. Our evidence suggests that the appropriate timing of LC after ERCP is either the same day or within 72 hours for treating cholelithiasis patients based on the severity of disease.

Backgrounds/Aims: Routine execution of intraoperative cholangiography (IOC) in laparoscopic cholecystectomy (LC) is considered a good practice to help early identification of biliary duct injuries (BDIs) or common bile duct (CBD) stones. This study aimed to determine the impact of IOC during LC. Methods: This is a retrospective, monocentric study, including patients with a LC performed from January 2020 to December 2021. Results: Of 303 patients, 215 (71.0%) were in the IOC group and 88 (29.0%) in the no-IOC group. IOC was incomplete or unclear in 10.7% of patients, with a failure rate of 14.7%. Operating time was 15 minutes longer in the IOC group (p = 0.01), and postoperative complications were higher (5.1% vs. 0.0%, p = 0.03). There were three BDIs (0.99%), all included in the IOC group; only one was diagnosed intraoperatively, and the other two were identified during the postoperative course. Regarding identifying CBD stones, IOC showed a sensitivity of 77%, a specificity of 98%, an accuracy of 97.2%, a positive predictive value of 63% and a negative predictive value of 99%. Conclusions: Systematic IOC has shown no specific benefits and prolonged operative duration. IOC should be performed on selected patients or in situations of uncertainty on the anatomy.

Backgrounds/Aims: Postoperative pain management is a key to enhanced recovery after surgery. The aim of this study was to evaluate clinical effect of preoperative intravenous (IV) non-steroidal anti-inflammatory drugs (NSAIDs) on relief of postoperative pain in patients after laparoscopic cholecystectomy. Methods: This single center, retrospective study was conducted between September 2019 and May 2020. A total of 163 patients were divided into two groups: Ibuprofen group (preoperative IV ibuprofen, n = 77) and Ketorolac group (preoperative IV ketorolac, n = 86). The primary outcome was postoperative pain score measured immediately in the recovery room. Results: There was no difference in demographic characteristics between the two groups of patients. Postoperative pain score measured immediately in the recovery room was significantly higher in the Ibuprofen group than in the Ketorolac group (mean value: 5.09 vs. 4.61; p = 0.027). The number of patients who needed analgesics immediately in the recovery room was also higher in the Ibuprofen group than in the Ketorolac group (28 [36.4%] vs. 18 [20.9%]; p = 0.036). Conclusions: In this study, preoperative IV injection with ketorolac reduced postoperative pain and analgesic requirement in the recovery room more effectively than that with ibuprofen. However, both showed similar effects on peak pain and pain at discharge. Numbers of patients requiring additional analgesics were also similar between the two groups.

Background: Establishment of laparoscopic cholecystectomy as an outpatient procedure has accentuated the clinical importance of reducing early postoperative pain, as well as postoperative nausea and vomiting (PONV). We therefore planned to evaluate the role of a multimodal approach in attenuating these problems. Methods: One hundred and twenty adult patients of ASA physical status I and II and undergoing elective laparoscopic cholecystectomy were included in this prospective, randomized, placebo-controlled study. Patients were divided into four groups of 30 each to receive methylprednisolone 125 mg intravenously or etoricoxib 120 mg orally or a combination of methylprednisolone 125 mg intravenously and etoricoxib 120 mg orally or a placebo 1 hr prior to surgery. Patients were observed for postoperative pain, fentanyl consumption, PONV, fatigue and sedation, and respiratory depression. Results were analyzed by the ANOVA, a Chi square test, the Mann Whitney U test and by Fisher's exact test. P values of less than 0.05 were considered to be significant. Results: Postoperative pain and fentanyl consumption were significantly reduced by methylprednisolone, etoricoxib and their combination when compared with placebo (P<0.05). The methylprednisolone + etoricoxib combination caused a significant reduction in postoperative pain and fentanyl consumption as compared to methylprednisolone or etoricoxib alone (P<0.05); however, there was no significant difference between the methylprednisolone and etoricoxib groups (P>0.05). The methylprednisolone and methylprednisolone + etoricoxib combination significantly reduced the incidence and severity of PONV and fatigue as well as the total number of patients requiring an antiemetic treatment compared to the placebo and etoricoxib (P<0.05). Conclusions: A preoperative single-dose administration of a combination of methylprednisolone and etoricoxib reduces postoperative pain along with fentanyl consumption, PONV, antiemetic requirements and fatigue more effectively than methylprednisolone or etoricoxib alone or a placebo.

Objective: The purpose of the study was to investigate the time from the injection of muscle relaxants to the first spontaneous respiration between sugammadex and conventional reversal for patients undergoing laparoscopic cholecystectomy. Methods: This study was retrospectively conducted on patients who were diagnosed with gallbladder stone (N802) between January 2014 and April 2017. The data were collected from the electronic medical records of a total of 186 patients (84 patients in the neostigmine group and 102 patients in the sugammadex group). Results: The time required for the first spontaneous respiration in the sugammadex group was shorter than that in the neostigmine group (3.6 min vs 4.9 min; p<0.05). After the injection of intermediate muscle relaxants, the comparison of heart rate and mean arterial pressure in the sugammadex and neostigmine groups revealed that the heart rate in the neostigmine group was higher than in the sugammadex group after 5 min (p<0.05). The mean arterial pressure in the neostigmine group was higher than in the sugammadex group after 10 min (p<0.05). A significant adverse effect of tachycardia was observed in the neostigmine group (p<0.05), but the frequency of rescue antiemetic in the sugammadex group was significantly higher than in the neostigmine group (p<0.05). Conclusion: In this study, the unwanted effect of neostigmine group was tachycardia; therefore, in the case of patients with hemodynamic instability, sugammadex is recommended. At 12 hours after the injection of sugammadex to patients, more antiemetics were required than in the neostigmine group; therefore, more research should be conducted on postoperative nausea and vomiting.

Laparoscopic cholecystectomy is of one the most common general surgical operations performed today. Concomitant choledocholithiasis occurs in roughly 10-20% of patients with symptomatic gallstones. Laparoscopic bile duct exploration (LBDE) offers a single-stage minimally-invasive solution to the management of choledocholithiasis. LBDE may be performed either via the transcystic route or via laparoscopic choledochotomy. A number of strategies to improve success are available to the surgeon to help in the problem of complicated choledocholithiasis, these range from simple maneuvers to the use of laser or mechanical lithotriptors. With the advances in laparoscopic surgery, it is also possible to handle complex surgical conditions such as Mirizzi syndrome or recurrent pyogenic cholangitis laparoscopically, even though these have yet to be accepted as standard of care. Following laparoscopic choledochotomy, options for closure include: primary closure, closure over a T-tube, and closure over an endobiliary stent. T-tube placement has been associated with increased operating time and hospital length of stay compared to primary closure, with no significant differences in morbidity. Based on the available literature, LBDE appears comparable to ERCP with regards to procedural efficacy and morbidity. LBDE remains relevant to the general surgeon and is best viewed as being complementary to endoscopic therapy in the management of choledocholithiasis.

Backgrounds/Aims: Bile duct stones (BDS) can be managed either prior to laparoscopic cholecystectomy (LC) using endoscopic retrograde cholangiopancreatography (ERCP) or with laparoscopic bile duct exploration (LBDE) at the time of LC. The latter is underutilised. The aim of this study was to use the dataset of the previously performed CholeS study to investigate LBDE hospital volumes, LBDE-to-LC rates, and LBDE outcomes. Methods: Data from 166 United Kingdom/Republic of Ireland hospitals were used to study the utilisation of LBDE in LC patients. Results: Of 8,820 LCs performed, 932 patients (10.6%) underwent preoperative ERCP and 256 patients (2.9%) underwent LBDE. Of the 256 patients who underwent LBDE, 73 patients (28.5%) had undergone prior ERCP and 112 patients (43.8%) had undergone prior magnetic resonance cholangiopancreatography. Fifteen (9.0%) of the 166 included hospitals performed less than five LBDEs in the two-month study period. LBDEs were mainly performed by upper gastrointestinal surgeons (84.4%) and colorectal surgeons (10.0%). Eighty-seven percent of the LBDEs were performed by consultants and 13.0% were performed by trainees. The laparoscopic-to-open conversion rate was 12.5%. The median operation time was 111 minutes (range: 75-155 minutes). Median hospital stay was 6 days (range: 4-11 days) for emergency LBDEs and 1 day (range: 1-4 days) for elective LBDEs. Overall morbidity was 21.5%. Bile leak rate was 5.3%. Thirty-day readmission and mortality rates were 12.1% and 0.4%, respectively. Conclusions: The single-stage approach to managing BDS was underutilised. An additional prospective study with a longer study period is needed to verify this finding.
