[Prognosis of a high risk of non-alcoholic fatty liver disease in the long-term period of laparoscopic cholecystectomy in the elderly and senile.]

After cholecystectomy, elderly patients require special attention, due to the influence of involution processes in the body on the formation of complications. To identify prognostic criteria for the formation of fatty liver degeneration in the long-term period of minimally invasive cholecystectomy, 159 men were examined. Dysregulation of the biliary tract was determined using magnetic resonance cholangiopancreatography, elastography and magnetic resonance imaging of the liver. Microbial markers of the wall microbiome of the intestine were determined using chromatography-mass spectrometry. The relationship between an increase in body mass index and a decrease in the amount of obligate microbiome (r=-0,43, p<0,050), as well as with the formation of fatty liver degeneration in elderly patients, was revealed. The features of vegetative regulation in elderly people with fatty liver degeneration have been determined. It has been proven that in old age, a decrease in the number of obligate anaerobic association of microorganisms of the small intestine (on average from 15 659 to 7 630 in persons of the 2nd age subgroup and from 1 457 to 17 837 in the 3rd) is a predictor of fatty liver degeneration. The prognostic algorithm developed on the basis of the analysis of highly informative signs makes it possible to identify with an accuracy of at least 75% a high risk of fatty liver degeneration in the long-term period of cholecystectomy.

Changes in blood catecholamines during induction of general anesthesia in patients with post-induction hypotension undergoing laparoscopic cholecystectomy: A single-center prospective cohort study.

BACKGROUND: Post-induction hypotension (PIH) often occurs during general anesthesia induction. This study aimed to investigate blood catecholamine levels during induction of general anesthesia in patients with PIH undergoing laparoscopic cholecystectomy. METHODS: This prospective study included 557 adult patients who underwent laparoscopic cholecystectomy under general anesthesia. PIH was defined as a greater than 20% decrease in systolic blood pressure from the pre-induction value, a systolic arterial pressure of less than 90 mmHg, or both. Plasma concentrations of epinephrine and norepinephrine during the induction of general anesthesia were determined using enzyme-linked immunosorbent assay. Multivariate logistic regression analysis evaluated the association between the clinical factors and PIH. RESULTS: Of the 557 patients, 390 had PIH, and the remaining 167 were allocated to the non-PIH group. Changes in blood adrenaline, noradrenaline levels, or both were more pronounced in the PIH than in the non-PIH group (p<0.05). Age, body mass index, a history of hypertension, preoperative systolic blood pressure, and propofol or sufentanil dose were independent predictors of PIH. CONCLUSION: The changes of blood catecholamines in patients with more stable hemodynamics during the induction of general anesthesia are smaller than that in patients with post-induction hypotension.

30-day outcomes in 1 000 consecutive laparoscopic cholecystectomies undertaken in four Cape metropole public hospitals.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the standard of care for symptomatic gallstone disease. The procedure has a steep learning curve and may result in significant postoperative morbidity and mortality. LC carries a morbidity of 1.6-5.3%, a mortality of 0.05-0.14% and readmission rates of 3.3% (0-11.7%). We aimed to evaluate the 30-day outcomes of LC across four metropole hospitals in the Western Cape (WC) including mortality, length of stay, readmissions and complications according to the Clavien-Dindo classification system. METHODS: A retrospective review of a prospective database was performed. Data were collected between September 2019 and July 2022. Relative clinical, operative findings and postoperative outcomes were analysed. RESULTS: There were 1 000 consecutive LCs included in this study. The mean postoperative length of stay was 1.92 days. Forty surgical complications were noted of which the most common were a bile leak (n = 14) and intra-abdominal collections (n = 11). Seven patients with bile leaks required reintervention. Four (0.4%) bile duct injuries (BDI) were reported in our series. Twenty-five percent of postoperative complications were graded as Clavien-Dindo IIIa and 28% were graded as Clavien-Dindo IIIb. The 30-day readmission rate was 3.8% (n = 38). Thirty-five patients were readmitted with surgical complications. There were three reported deaths (0.3%). CONCLUSION: Laparoscopic cholecystectomy is considered the standard of treatment for gallstone disease but a small percentage may have serious complications. The outcomes reported in this series are similar to that of other reported studies.

Life-Threatening Tracheal Diverticulum Rupture Following Laparoscopic Cholecystectomy: A Rare Case Report.

BACKGROUND We present an exceptional case of asystole and tracheal diverticulum rupture as a result of cardiopulmonary resuscitation (CPR) immediately following laparoscopic cholecystectomy performed at Riga 1st Hospital. Tracheal rupture after tracheal intubation is a severe but very rare complication that can be fatal. We present an incidental finding of the tracheal diverticulum and its rupture during CPR. CASE REPORT A 71-year-old woman (American Society of Anesthesiologists class II, body mass index 28.58) underwent a planned laparoscopic cholecystectomy. Preoperative chest X-ray showed no abnormalities. Endotracheal intubation was performed, with the first attempt with a 7-mm inner diameter cuffed endotracheal tube without an introducer. Five minutes after rapid desufflation of the pneumoperitoneum, severe bradycardia and hypotension occurred, followed by asystole. CPR was performed for a total of 2 min, until spontaneous circulation returned. Twenty hours after surgery, subcutaneous emphysema appeared on the chest. Computed tomography scan of the chest revealed subcutaneous neck emphysema, bilateral pneumothorax, extensive pneumomediastinitis, and a pocket-like, air-filled tissue defect measuring 10×32 mm in the distal third of the trachea, with suspected rupture. Two hours after the diagnosis was established, the emergent surgery was performed. The patient was completely recovered after 15 days. CONCLUSIONS Our case illustrates that tracheal diverticula is sometimes diagnosed by accident and too late, which then can lead to life-threatening situations. Tracheal rupture can be made not only by mechanical piercing by an endotracheal tube but also during interventions, such as CPR. Rapid desufflation of the pneumoperitoneum can lead to asystole, induced by the Bezold-Jarisch reflex.

Unusual case of Niemeier type II gallbladder perforation: case report and literature review.

Niemeier type II gallbladder perforation (GBP) is caused by inflammation and necrosis of the gallbladder wall followed by bile spilling into the abdominal cavity after perforation. The gallbladder then becomes adhered to the surrounding inflammatory tissue to form a purulent envelope, which communicates with the gallbladder. At present, the clinical characteristics and treatment of type II GBP are not well understood and management of GBP remains controversial. Type II GBP with gastric outlet obstruction is rare and prone to misdiagnosis and delayed treatment. Recent systematic reviews report that percutaneous drainage does not influence outcomes. In this current case, due to the high risk of bleeding and accidental injury, as well as a lack of access to safely visualize the Calot's triangle, the patient could not undergo laparoscopic cholecystectomy, which would have been the ideal option. This current case report presents the use of percutaneous laparoscopic drainage combined with percutaneous transhepatic gallbladder drainage in a patient with type II GBP associated with gastric outlet obstruction. A review of the relevant literature has been provided in addition to a summary of the clinical manifestations and treatments for type II GBP.

[Minimally invasive interventions for complications associated with intra-abdominal calculi after laparoscopic cholecystectomy]. / Vozmozhnosti minimal'no invazivnykh vmeshatel'stv v lechenii oslozhnenii, svyazannykh s vnutribryushnymi konkrementami posle videolaparoskopicheskoi kholetsistektomii.

OBJECTIVE: To study the possibilities of minimally invasive methods for removing intra-abdominal calculi after laparoscopic cholecystectomy. MATERIAL AND METHODS: There were 5 patients with abdominal abscesses associated with infected calculi after previous laparoscopic cholecystectomy at the Sklifosovsky Research Institute for Emergency Care between 2020 and 2023. Mean age of patients was 55±12 years. There were 3 (60%) women and 2 (40%) men. All patients underwent minimally invasive treatment. RESULTS: Four patients (80%) underwent percutaneous drainage of abscess with subsequent replacement by larger drains and removal of calculi with endoscopic assistance. Event-free period after cholecystectomy was 44±32 months. One patient developed subhepatic abscess in 72 months after laparoscopic cholecystectomy. This patient underwent transluminal removal of calculus through the duodenal wall. There was 1 calculus in 3 (60%) patients, 2 calculi in 1 (20%) patient and 3 calculi in 1 (20%) patient. CONCLUSION: The above-mentioned cases demonstrate successful minimally invasive interventions for symptomatic abdominal calculi after laparoscopic cholecystectomy. Minimally invasive treatment can reduce surgical aggression and accelerate rehabilitation.

Late port-site metastasis of unexpected gallbladder carcinoma after laparoscopic cholecystectomy: A case report.

INTRODUCTION: Incidental gallbladder carcinoma refers to a discovery of gallbladder cancer during or after cholecystectomy. Late port-site metastasis (PSM) following Laparoscopic cholecystectomy (LC) is rare with an incidence rate of 10.3%. PATIENT CONCERNS: We report a case of a 58-year-old man who presented with a painful abdominal wall mass for 6 weeks. He had a history of LC for symptomatic cholelithiasis, 8 years prior. DIAGNOSIS: Histopathological examination revealed a positive result for metastatic adenocarcinoma from the abdominal wall mass. Moreover, Positron emission tomography (PET) showed a small focus of intense fluorodeoxyglucose (FDG) uptake in the gallbladder bed, which was highly suspicious for malignancy. INTERVENTION: Decision was to proceed with surgery owing to uptake in the gallbladder bed with single-site metastasis to the previous port site. In addition, in the board meeting, an agreement was reached for performing distal pancreatectomy with splenectomy owing to uncertainty of malignancy based on what was discovered during the full metastatic workup. Diagnostic laparoscopy followed by midline laparotomy performed. Radical completion cholecystectomy with lymphadenectomy was done. Followed by complete resection of the anterior abdominal wall. Distal pancreatectomy and splenectomy were then performed. OUTCOME: Pathological diagnosis showed metastatic/invasive, moderately differentiated adenocarcinoma with positive margins on the posterior surface of excised port-site mass. The positive margins necessitated further chemoradiotherapy, followed by adjuvant chemotherapy until lung metastasis was identified. After this, the patient was scheduled for palliative chemotherapy. CONCLUSION: Presence of PSM is often associated with peritoneal metastasis. For this reason, it is advised to evaluate the patient for possible metastasis.

Ultrasound-guided subcostal approach of transversus abdominis plane block compared with wound infiltration for postoperative analgesia following laparoscopic cholecystectomy: A systematic review and meta-analysis.

BACKGROUND: Despite laparoscopic cholecystectomy (LC) is a commonly performed operation under ambulatory setting, significant postoperative pain is still a major concern. The ultrasound-guided subcostal approach of transversus abdominis plane (sTAP) blocks and wound infiltration (WI) are both widely practiced techniques to reduce postoperative pain in patients undergoing LC. Although these methods have been shown to relieve postoperative pain effectively, the relative analgesic efficacy between ultrasound-guided sTAP blocks and WI is not well known. METHODS: We searched PubMed, EMBASE, and CENTRAL to identify all randomized controlled trials (RCTs) comparing ultrasound-guided sTAP block versus WI for postoperative pain control in adult patients undergone LC. The search was performed until May 2023. Primary outcome was defined as 24-hour cumulative opioid consumption. Secondary outcomes were postoperative pain scores and the incidence of postoperative nausea and vomiting (PONV). RESULTS: Finally, 6 RCTs were included, and data from 314 participants were retrieved. Postoperative 24-hour opioid consumption was significantly lower in ultrasound-guided sTAP group than in the WI group with a mean difference of -6.67 (95% confidence interval: -9.39 to - 3.95). The ultrasound-guided sTAP group also showed significantly lower pain scores. Incidence of PONV did not significantly differ between the 2 groups. CONCLUSIONS: We conclude that there is low to moderate evidence to advocate that ultrasound-guided sTAP block has better analgesic effects than WI in patients undergoing LC. Further trials are needed with robust methodology and clearly defined outcomes.

Aeromonas hydrophila induced necrotizing fasciitis following laparoscopic cholecystectomy.

Necrotizi ng fasciit is [NF] i s a m ultifaceted disease of the muscle fascia and body tissues which demands the earliest intervention. Past reviews have documented ver y few cases of Aeromonas Hydroph ila [AH] induced N F fol lo wing abdominal surgery. AH can cause fatal NF as seen in a 72 year old female patient reported at Liaquat National Hospital &Medical College; a ter tiary care center in Karachi, Pakistan on 2nd April, 2022. She had a k nown comorbidity of hypertension and presented with the chief complaint of symptomatic gallstones for which she unde rwent Laparoscopic Cholecystectomy (LAPCHOL). She developed NF of the lower ab domen post- oper atively. Following uneventful Laparoscopic Cholecystectomy our pati ent presented to the ER two days later with severe lower abdo minal pain and overlyi ng celluliti s. Fasc io to my revealed extensive myonecrosis with necrotizing soft tissue in fe ction. Despite u ndergoing extensive surgical debr idement and broad spectr um antibi ot ic administration; the patient died in the ICU on the fifth postoperat ive day followi ng septic complications. Histopathologica l an alysis, confirmed i nflammat ion and necrosis. Culture sensitivity of the debrided tissue revealed AH. Approach should lie towards analyzing the behaviour of such microbes in high risk patients through collective case studies. This is the first clinical case showcasing such parameters e ncountered in the General Surger y Department.

Preoperative difficulty factors in delayed laparoscopic cholecystectomy: Tokyo Guidelines 2018 surgical difficulty score analysis.

INTRODUCTION: Tokyo Guidelines 2018 (TG18) recommend early laparoscopic cholecystectomy (LC) for low-risk acute cholecystitis (AC); however, some patients undergo delayed LC (DLC) after conservative treatment. DLC, influenced by chronic inflammation, is a difficult procedure. Previous studies on LC difficulty lacked objective measures. Recently, TG18 introduced a novel 25 findings difficulty score, which objectively assesses intraoperative factors. The purpose of this study was to use the difficulty score proposed in TG18 to identify and investigate the predictors of preoperative high-difficulty cases of DLC for AC. METHODS: We retrospectively reviewed 100 patients with DLC after conservative AC treatment. The surgical difficulty of DLC was evaluated using a difficulty score. Based on previous studies, the highest scores in each category were categorized as grades A-C. RESULTS: The severity of AC was mild in 51 patients and moderate in 49. Surgical outcomes revealed a distribution of difficulty scores, with grade C indicating high difficulty, showing significant differences in operative time, blood loss, achieving a critical view of safety, bailout procedures, and postoperative hospital stay compared with grades A and B. Regarding the preoperative risk factors, multivariate analysis identified age >61 years (p = .008), body mass index >27.0 kg/m2 (p = .007), and gallbladder wall thickness >6.2 mm (p = .001) as independent risk factors for grade C in DLC. CONCLUSION: The difficulty score proposed in TG18 provides an objective framework for evaluating surgical difficulty, allowing for more accurate risk assessments and improved preoperative planning in DLC for AC.

[Expert consensus on the laparoscopic radical resection of gallbladder cancer(2023)].

The incidence of gallbladder cancer has been increasing. Radial resection is still the most promising curable treatment for patients with gallbladder cancer. Although the techniques required for laparoscopic radical resection of gallbladder cancer have matured, the number of reports is also on the rise, and laparoscopic radical resection of gallbladder cancer is still controversial. To standardize laparoscopic radical resection of gallbladder cancer, the Biliary Surgery Branch, Chinese Society of Surgery, Chinese Medical Association, together with the Chinese Medical Doctor Association in Chinese Committee of Biliary Surgeons, gathered experts to formulate recommendations and consensus on laparoscopic radical resection of gallbladder cancer. This consensus includes several parts: safety, preoperative evaluation, indications, surgical team, positioning of patient and trocars, intraoperative frozen examination, lymph node dissection, liver resection,bile duct resection, etc. Furthermore, suggestions on the principle of treatment, surgical procedures, and precautions were also provided for patients with delayed diagnoses of gallbladder cancer undergoing resection. This consensus aims to offer valuable suggestions for the standardization of laparoscopic radical resection of gallbladder cancer.

Use of artificial intelligence in the detection of the critical view of safety during laparoscopic cholecystectomy.

BACKGROUND: This study aimed to evaluate the use of artificial intelligence (AI) to detect the critical view of safety during elective laparoscopic cholecystectomy. METHODS: This was a prospective, observational study evaluating the detection of the critical view of safety with an AI software in a consecutive series of elective laparoscopic cholecystectomies compared with the blinded evaluation of 3 surgeons. The program was created using the digital tools PyCharm (JetBrains), Google Colab Pro (https://colab.google/), and YOLOv8 (Ultralytics). RESULTS: A total of 40 consecutive elective laparoscopic cholecystectomies were included in the study. The program was able to detect the critical view of safety in all cases following the experts' blinded opinion. CONCLUSION: In this preliminary experience, an AI software was able to detect the critical view of safety in elective laparoscopic cholecystectomies. Its application during nonelective cases, in which the critical view of safety is harder to achieve, might warrant further studies.

Patient-reported Outcome Measure (PROM) Rand-36-item Health Survey for Gallstone Disease Patients Five Years Following Surgery: A Prospective Randomized Study.

BACKGROUND/AIM: There are no studies assessing the long-term quality of life (QoL) following three-dimensional laparoscopy cholecystectomy (3D-LC) in patients with cholelithiasis (Chole). PATIENTS AND METHODS: A cohort of 200 patients with Chole were randomized into 3D-LC or minilaparotomy cholecystectomy (MC) groups. RAND-36 survey was performed before randomization, four weeks and five years postoperatively. RESULTS: Similar postoperative five years RAND-36 scores were reported in the 3D-LC and MC groups. The MC and 3D-LC groups combined analysis, social functioning (SF, p=0.007), mental health (MH, p=0.001), role physical (RP, p<0.001) and bodily pain (BP, p<0.001) domains increased significantly. In comparison to the Finnish reference RAND-36 (FRR) scores, the scores at five years increased significantly in the MH domain, while four RAND-36 domains; Physical functioning (PF), general health (GH), RP, BP remained significantly lower in comparison to the FRR scores. CONCLUSION: A relatively similar long-term outcome in the 3D-LC and MC patients is shown. Interestingly, five RAND-36 domains increased during five years follow-up, while four RAND-36 domains remained lower than FRR scores, which may indicate onset of possible new symptoms following cholecystectomy in long-term follow-up.

What Happens After Discharge? A 2+ Year Follow-Up After Laparoscopic Subtotal Fenestrating and Reconstituting Cholecystectomy.

Laparoscopic subtotal cholecystectomy (LSC) is utilized to prevent complications in the difficult cholecystectomy. Medium-term outcomes are poorly studied for fenestrating and reconstituting operative techniques. A single-institution retrospective review was undertaken of all LSCs. A telephone survey was used to identify complications addressed at other institutions. We performed subgroup analyses by operative approach and of patients requiring postoperative endoscopic intervention (ERC). 28 patients met inclusion criteria. The median follow-up was 32.7 months. There were no bile duct injuries or reoperations. 21% of patients required a postoperative ERC and 50% were discharged home with a drain. Bile leaks were found to be more prevalent in the fenestrating LSC group (38% vs 0%, P = .003). The case series suggested more severe recurrent biliary disease in patients undergoing reconstituting LSC. Laparoscopic subtotal cholecystectomy appears to have satisfactory medium-term outcomes. The reconstituting LSC group trends toward more severe recurrent disease which warrants further investigation.

Laparoscopic subtotal cholecystectomy outcomes across a low-and middle-income country metropolitan health service.

BACKGROUND: Laparoscopic subtotal cholecystectomy (LSC) is a safe alternative for difficult cholecystectomies to prevent bile duct injury and open conversion. The primary aim was to detail the use and outcomes on LSCs. METHODS: Retrospective analysis of a prospectively maintained database of laparoscopic cholecystectomy (LC). Relative clinical factors, outcomes, and 30-day follow-up between LSC and LC were compared using univariate and multivariate analyses. RESULTS: Six hundred and twenty four cholecystectomies were performed and 53 (8.5%) required LSC. 81.8% were fenestrating LSC. Male sex was significantly overrepresented in the LSC group (p < 0.01) and patients requiring LSC were significantly older (p < 0.01). Same admission cholecystectomy was associated with a higher risk of LSC (p < 0.01). Patients with a history of previous surgery, preoperative ERCP, or percutaneous cholecystostomy had an increased risk of undergoing LSC (p < 0.01). A necrotic gallbladder was the most significant predictor of the need for a LSC (p < 0.001). A contracted gallbladder, extensive adhesions, gallbladder empyema, and severe inflammation were significant predictors of difficulty (all p < 0.01). Postoperative complications occurred in 26.4% of LSC patients. There were ten (18.9%) Clavien-Dindo Grade III complications, 5.7% required ERCPs, and 9.4% required relook laparotomies. Significantly, more patients in the LSC group developed bile leaks (n = 8, 15%) (p < 0.001). There were two readmissions within 30 days, one mortality, and no BDIs occurred in the LSC cohort. CONCLUSION: LSC provides a feasible surgical option that should be utilized in complex cholecystitis.

The Effect of Clonidine Premedication on Hemodynamic Changes Following Tracheal Intubation and Co2 Gas Insufflation and Postoperative Shivering In Patients Undergoing Laparoscopic Cholecystectomy; a Randomized Clinical Trial.

BACKGROUND: Laparoscopic cholecystectomy is a proper treatment for cholecystitis but the Carbon dioxide gas which is used in surgery stimulates the sympathetic system and causes hemodynamic changes and postoperative shivering in patients undergoing operations. This study was conducted to evaluate the effects of clonidine on reducing hemodynamic changes during tracheal intubation and Carbon dioxide gas insufflation and postoperative shivering in patients undergoing laparoscopic cholecystectomy. MATERIAL AND METHODS: This prospective, randomized, triple-blind clinical trial was conducted on 60 patients between the 18-70 years-old age group, who were candidates of laparoscopic cholecystectomy surgery. The patients randomized into two groups (30 patients received 150 µg oral clonidine) and 30 patients received 100 mg oral Vitamin C). Heart rate and mean arterial pressure of patients were recorded before anesthesia, before and after laryngoscopy, before and after Carbon dioxide gas insufflation. Data were analyzed using Chi-2, student t-test, and analysis of variance by repeated measure considering at a significant level less than 0.05. RESULTS: The findings of this study showed that both heart rate and mean arterial pressure in clonidine group after tracheal intubation and Carbon dioxide gas insufflation were lower than patients in the placebo group, but there was not any statistically significant difference between the two groups (p>0.05) and also postoperative shivering was not different in groups. There was no significant statistical difference in postoperative shivering between the two groups (p>0.05). CONCLUSION: Using 150 µg oral clonidine as a cheap and affordable premedication in patients undergoing laparoscopic cholecystectomy improves hemodynamic stability during operation.

Pre-incisional local infiltration with levobupivacaine in laparoscopic cholecystectomy: a randomized and clinical trial.

OBJECTIVE: Laparoscopic cholecystectomy (LC), despite its minimally invasive nature, requires effective control of post-operative pain. The use of local anesthetics (LA) has been studied, but the level of evidence is low, and there is little information on important parameters such as health-related quality of life (HRQoL) or return to work. The objective of the study was to evaluate the efficacy of 0.50% levobupivacaine infiltration of incisional sites in reducing POP after LC. METHODS: This was a prospective, randomized, double-blind study. Patients undergoing elective LC were randomized into two groups: no infiltration (control group) and port infiltration (intervention group). POP intensity (numerical rating scale, NRS), need for rescue with opioid drugs, PONV incidence, HRQoL, and return to work data, among others, were studied. RESULTS: Two hundred and twelve patients were randomized and analyzed: 105 (control group) and 107 (intervention group). A significant difference was observed in the NRS values (control group mean NRS score: 3.41 ± 1.82 vs. 2.56 ± 1.96) (p < 0.05) and in the incidence of PONV (31.4% vs. 19.6%) (p = 0.049). CONCLUSIONS: Levobupivacaine infiltration is safe and effective in reducing POP, although this does not lead to a shorter hospital stay and does not influence HRQoL, return to work, or overall patient satisfaction.

OBJETIVO: la colecistectomía laparoscópica (CL), a pesar de su carácter mínimamente invasivo, requiere un control efectivo del dolor postoperatorio (POP). El uso de anestésicos locales (AL) ha sido estudiado pero el nivel de evidencia es bajo y existe poca información acerca de parámetros relevantes como la calidad de vida relacionada con la salud (CVRS) o la reincorporación laboral. El objetivo de este estudio es analizar la eficacia de la infiltración de los sitios incisionales con levobupivacaína 0,50% en la reducción del dolor postoperatorio tras la CL. MATERIAL Y MÉTODOS: estudio prospectivo, aleatorizado y doble ciego. Pacientes sometidos a CL programada fueron aleatorizados en dos grupos: sin infiltración (grupo control) y con infiltración preincisional (grupo intervención). La intensidad del dolor (escala de puntuación numérica, NRS), la necesidad de rescates con opioides, la incidencia de náuseas o vómitos postoperatorios (NVPO) y datos de CVRS o reincorporación laboral, entre otros, fueron recogidos. RESULTADOS: 212 pacientes fueron aleatorizados y analizados: 105 en el grupo control y 107 en el grupo de intervención. Se observó una diferencia estadísticamente significativa en la intensidad del dolor (puntuación media NRS: 3.41 ± 1.82 vs. 2.56 ± 1.96) (p < 0.05) y en la incidencia de NVPO (31.4% vs. 19.6%) (p = 0.049). CONCLUSIONES: La infiltración con levobupivacaína es segura y efectiva en la reducción del dolor postoperatorio, aunque esto no conlleva una menor estancia hospitalaria y no influye en los resultados de CVRS, reincorporación laboral o satisfacción del paciente.

Risk factors for readmission after a cholecystectomy: a case-control study.

OBJECTIVE: The aim of this study was to assess the risk factors associated with 30-day hospital readmissions after a cholecystectomy. METHODS: We conducted a case-control study, with data obtained from UC-Christus from Santiago, Chile. All patients who underwent a cholecystectomy between January 2015 and December 2019 were included in the study. We identified all patients readmitted after a cholecystectomy and compared them with a randomized control group. Univariate and multivariate analyses were conducted to identify risk factors. RESULTS: Of the 4866 cholecystectomies performed between 2015 and 2019, 79 patients presented 30-day hospital readmission after the surgical procedure (1.6%). We identified as risk factors for readmission in the univariate analysis the presence of a solid tumor at the moment of cholecystectomy (OR = 7.58), high pre-operative direct bilirubin (OR = 2.52), high pre-operative alkaline phosphatase (OR = 3.25), emergency admission (OR = 2.04), choledocholithiasis on admission (OR = 4.34), additional surgical procedure during the cholecystectomy (OR = 4.12), and post-operative complications. In the multivariate analysis, the performance of an additional surgical procedure during cholecystectomy was statistically significant (OR = 4.24). CONCLUSION: Performing an additional surgical procedure during cholecystectomy was identified as a risk factor associated with 30-day hospital readmission.

OBJETIVO: El objetivo de este estudio fue evaluar los factores de riesgo asociados al reingreso hospitalario en los primeros 30 días post colecistectomía. MÉTODOS: Estudio de casos-controles con datos obtenidos del Hospital Clínico de la UC-Christus, Santiago, Chile. Se ­incluyeron las colecistectomías realizadas entre los años 2015-2019. Se consideraron como casos aquellos pacientes que reingresaron en los 30 primeros días posterior a una colecistectomía. Se realizó un análisis univariado y multivariado de diferentes posibles factores de riesgo. RESULTADOS: De un total de 4866 colecistectomías, 79 pacientes presentaron reingreso hospitalario. Los resultados estadísticamente significativos en el análisis univariado fueron; tumor sólido al momento de la colecistectomía (OR = 7.58) bilirrubina directa preoperatoria alterada (OR = 2.52), fosfatasa alcalina preoperatoria alterada (OR = 3.25), ingreso de urgencia (OR = 2.04), coledocolitiasis al ingreso (OR = 4.34) realización de otros procedimientos (OR = 4.12) y complicaciones postoperatorias. En el análisis multivariado sólo la realización de otro procedimiento durante la colecistectomía fue estadísticamente significativa (OR = 4.24). CONCLUSIÓN: La realización de otros procedimientos durante la colecistectomía es un factor de riesgo de reingreso hospitalario en los 30 días posteriores a la colecistectomía.

Comparison of Nausea and Vomiting Incidence After Laparoscopic Cholecystectomy With Pretreatment With Haloperidol and Ondansetron: A Randomization Clinical Trial Study.

OBJECTIVE: Nausea and vomiting after surgery are the most common complications. Therefore, we performed this study to compare the effect of ondansetron and haloperidol on nausea and vomiting after laparoscopic cholecystectomy. PATIENTS AND METHODS: In this randomized clinical trial, 60 patients candidates for elective laparoscopic cholecystectomy were allocated to haloperidol (0.05 mg/kg, n = 30) and ondansetron (0.15 mg/kg, n = 30) groups. An Ocular Analog Scale was used to assess postoperative nausea and vomiting. Every 15 minutes in the recovery room, heart rate and blood pressure were measured up to 6 hours after surgery. In addition, patient satisfaction was assessed postoperatively. RESULTS: Haloperidol and ondansetron have the same effect on postoperative nausea and vomiting in the recovery room and ward. It was found that the trend of Visual Analog Scale variable changes in the recovery room was similar in the haloperidol and ondansetron group ( P = 0.58); it was also true for the ward ( P = 0.79). Comparing the length of stay in a recovery room in the 2 groups was not statistically significant ( P = 0.19). In addition, the 2 groups did not differ in satisfaction postoperatively ( P = 0.82). CONCLUSION: Haloperidol and ondansetron had an equal effect on reducing nausea and vomiting in the recovery room and ward after laparoscopic cholecystectomy. Patient satisfaction and length of stay in the recovery room did not differ between groups.
