Laparoscopic cholecystectomy in day surgery: Feasibility and outcomes of the first 400 patients

Alteration of ascending colon mucosal microbiota in patients after cholecystectomy

BACKGROUND

Cholecystectomy is a successful treatment option for gallstones, although the incidence of colorectal cancer (CRC) has notably increased in post-cholecystectomy (PC) patients. However, it remains uncertain whether the altered mucosal microbiota in the ascending colon is related.

AIM

To investigate the potential correlation between gut microbiota and the surgical procedure of cholecystectomy.

METHODS

In total, 30 PC patients and 28 healthy controls underwent colonoscopies to collect mucosal biopsy samples. PC patients were divided based on their clinical features. Then, 16S-rRNA gene sequencing was used to analyze the amplicon, alpha diversity, beta diversity, and composition of the bacterial communities. Additionally, the Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) database, sourced from the Kyoto Encyclopedia of Genes and Genomes, was used to predict the functional capabilities of the bacteria.

RESULTS

PC patients were comparable with healthy controls. However, PC patients older than 60 years had a distinct composition compared to those under 60 years old. Bacteroidetes richness was considerably higher at the phylum level in PC patients. Bacteroides, Parabacteroides, and Bilophila were more abundant in the PC group than in the control group. Furthermore, PC patients exhibited greater enrichment in metabolic pathways, specifically those related to lipopolysaccharide biosynthesis and vancomycin group antibiotic production, than controls.

CONCLUSION

This study indicated that the mucosal microbiota in PC patients was altered, perhaps offering new perspectives on the treatment possibilities for CRC and diarrhea following cholecystectomy.

Personal versus therapist perioperative music intervention: a randomized controlled trial

INTRODUCTION

Music interventions can alleviate patient anxiety and improve post-surgical satisfaction. However, it remains uncertain whether personal music preferences affect efficacy. The authors tested whether personal music intervention with patient-selected songs played ad libitum is more effective than standard therapist-designed treatment with classical music.

METHODS

A prospective, parallel-group, single-blinded, randomized controlled trial with 229 participants (aged 18-60 years) previously scheduled for elective surgery. Data analyses followed a modified intention-to-treat principle. The patients were randomized into three groups: Standard care without music (Control), therapist-designed classic music treatment (TT), or personal music intervention with patient-selected songs played ad libitum by the patient (PI). All patients received standard post-anaesthesia care, and music intervention was started upon arrival at the post-anaesthesia care unit. Primary outcomes were anxiety and overall satisfaction at discharge. In contrast, secondary outcomes were systolic blood pressure during music intervention, the sleep quality of the night after surgery, and the occurrence of postoperative nausea and vomiting within the first 24 h after surgery.

RESULTS

Compared with therapist-designed music treatment, personal intervention decreased systolic blood pressure (T 0 : 124.3±13.7, 95% CI:121-127.7; T 20min : 117.6±10.4, 95% CI:115-120.1; T 30min : 116.9±10.6, 95% CI:114.3-119.4), prevented postoperative nausea and vomiting (Control: 55.9%, TT: 64.6%, PI: 77.6%), including severe postoperative nausea (VAS score>4; Control: 44.1%; TT: 33.8%; PI: 20.9%) and severe emesis (Frequency≥3, Control: 13.2%; TT: 7.7%; PI: 4.5%). None of the treatments affected sleep quality at night after surgery (Median, Q1-Q3, Control: 3, 1-3; TT: 3, 1-4; PI: 3, 1-3.5). Personal, but not therapist, music intervention significantly prevented anxiety (Control: 36.4±5.9, 95% CI:35.0-37.9; TT: 36.2±7.1, 95% CI: 34.4-37.9; PI: 33.8±5.6, 95% CI: 32.4-35.2) and emesis (Control: 23.9%; TT: 23.4%; PI: 13.2%) and improved patient satisfaction (Median, Q1-Q3, C: 8, 6-8; TT: 8, 7-9; PI: 8, 7-9).

CONCLUSIONS

Personal music intervention improved postoperative systolic blood pressure, anxiety, nausea, emesis, and overall satisfaction, but not sleep quality, as compared to therapist-designed classic intervention.

Cholecystectomy promotes the development of colorectal cancer by the alternation of bile acid metabolism and the gut microbiota

The incidence and mortality of colorectal cancer (CRC) have been markedly increasing worldwide, causing a tremendous burden to the healthcare system. Therefore, it is crucial to investigate the risk factors and pathogenesis of CRC. Cholecystectomy is a gold standard procedure for treating symptomatic cholelithiasis and gallstone diseases. The rhythm of bile acids entering the intestine is altered after cholecystectomy, which leads to metabolic disorders. Nonetheless, emerging evidence suggests that cholecystectomy might be associated with the development of CRC. It has been reported that alterations in bile acid metabolism and gut microbiota are the two main reasons. However, the potential mechanisms still need to be elucidated. In this review, we mainly discussed how bile acid metabolism, gut microbiota, and the interaction between the two factors influence the development of CRC. Subsequently, we summarized the underlying mechanisms of the alterations in bile acid metabolism after cholecystectomy including cellular level, molecular level, and signaling pathways. The potential mechanisms of the alterations on gut microbiota contain an imbalance of bile acid metabolism, cellular immune abnormality, acid-base imbalance, activation of cancer-related pathways, and induction of toxin, inflammation, and oxidative stress.

Patient selection for ambulatory laparoscopic cholecystectomy: A systematic review

Background

Currently, there is no consensus on patient selection for ambulatory laparoscopic cholecystectomy (LC). This study is a systematic review of previously published patient selection for ambulatory LC.

Methods

A comprehensive search was done in PubMed, Web of Science, Embase and Google Scholar Database up to March 2020 to summarise previously reported medical or surgical selection criteria used for inclusion and exclusion of patients, as well as successful same-day discharge rates and readmission rate after discharge.

Results

Fifty-nine studies with a total of 13,219 patients were included in this systematic review. In total, the median same-day discharge rate was 90% (range: 63%-99.4%), and median readmission rate was 2.22% (range: 0%-16.9%). The most considered medical criteria were American Society of Anesthesiologists classification I and II, age <70, and body mass index <35. Surgical criteria varied greatly. The top three accessible exclusion variables were (1) common bile duct stones, cholangitis, or jaundice (27 publications, 45.8%); (2) history of abdominal surgery (12 publications, 20.3%) and (3) history of pancreatitis (9 publications, 15.3%).

Conclusion

The results of the current study showed the variable patient selection in different centres, the medical aspect criteria may be expanded under adequate pre-anaesthetic assessment and preparation and the surgical aspect criteria should include more laboratory or imaging parameters to ensure the surgical safety.

Bacterial Alterations in Post-Cholecystectomy Patients Are Associated With Colorectal Cancer

Background: Although increasing evidences showed a correlation between cholecystectomy and the prevalence rate of colorectal cancer (CRC), and shed light on gut microbiota in colorectal pathogenesis, only a few studies focused on microbial alterations after cholecystectomy, and its sequent role in carcinogenesis and progression of CRC has not been reported. Thus, we aimed to investigate the bacterial alterations and tried to clarify their clinical significance.

Methods: 104 subjects were enrolled and divided into post-cholecystectomy patients (PC, n = 52) and healthy controls (HC, n = 52). To investigate the bacterial role in carcinogenesis, PC patients were further separated into preCA_CRC (patients with precancerous lesions and/or CRC, n = 9) and non-CA (patients without precancerous lesions and CRC, n = 43) based on the histopathology. Qualified stool samples were collected for 16S rRNA gene sequencing to analyze the bacterial profile.

Results: Our data showed noteworthy compositional and abundant alterations of bacterial microbiota in PC patients, characterized as Bacteroides ovatus, Prevotella copri, and Fusobacterium varium remarkably increased; Faecalibacterium prausnitzii, Roseburia faecis, and Bifidobacterium adolescentis significantly decreased. Additionally, the duration after cholecystectomy was the critical factor that affected bacterial composition. Machine learning-based analysis showed a pivotal role of Megamonas funiformis in discriminating PC from HC subjects and involving in the progression of CRC.

Conclusions: The bacterial dysbiosis may associate with CRC in PC patients, and the duration after cholecystectomy was highlighted as an important factor. Altered bacterial microbiota was likely to play a pivotal role in related-disease in the long-term follow-up of PC patients.

[Surgical treatment of acute calculous cholecystitis followed by one-day discharge of patients]

AIM

To develop rational tactics of surgical treatment of patients with acute calculous cholecystitis with their subsequent discharge within 1 day since admission.

MATERIAL AND METHODS

There were 283 patients with acute cholecystitis and 58 patients with chronic cholecystitis. All patients underwent laparoscopic cholecystectomy. Patients with acute cholecystitis were divided into 2 groups: main group - 136 patients were discharged within 1 day since admission, control group - 147 patients who were discharged later. Age, gender, duration of attack and ASA score were similar in both groups.

RESULTS

Incidence of intraoperative complications was significantly higher in the control group compared with the main group (6.1% vs. 0.7%). There were no postoperative complications in the main group; postoperative morbidity in the control group was 6.1%. Criteria preventing discharge within 1 day since admission were developed. Uneventful early postoperative period after laparoscopic cholecystectomy allows us to discharge 48% of patients with uncomplicated acute calculous cholecystitis within 1 day since hospitalization. The developed algorithm of treatment is followed by reduced hospital-stay by 4 days.

CONCLUSION

The developed algorithm of treatment of patients with acute calculous cholecystitis can reduce hospital-stay up to 1 day. Favorable early postoperative period and follow-up of patients after discharge are essential for safe treatment.

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.

Postoperative Symptom Distress of Laparoscopic Cholecystectomy Ambulatory Surgery Patients

PURPOSE

The purposes of this study were to (1) identify symptoms that cause postoperative distress in ambulatory surgery patients; (2) identify symptom management techniques that effectively reduce distress of laparoscopic cholecystectomy (LC) postoperative symptoms at home after ambulatory surgery; and (3) identify facilitators and barriers to self-management of postoperative symptoms.

DESIGN

A qualitative descriptive study.

METHODS

Two focus groups of ambulatory surgery patients who had experienced a laparoscopic cholecystectomy procedure and their caregivers were queried to elicit understanding of postoperative symptoms and symptom management techniques.

FINDINGS

Themes identified included distressing symptoms and consequences of surgery, symptom management, and self-management facilitators and barriers. Pain was a major symptom after surgery and impacted mobility and sleep. Participants in our study wanted realistic information about symptoms and more specific information on symptom management. Caregivers were important to the success of symptom management but experienced their own stress.

CONCLUSIONS

Perianesthesia nurses should focus not only on the immediate recovery, but also prepare patients and their caregivers for the more prolonged issues of recovery at home.

The clinical utility of pre-operative neutrophil-to-lymphocyte ratio as a predictor of outcomes in patients undergoing elective laparoscopic cholecystectomy

BACKGROUND

In recent years, there has been an increasing trend towards day-case surgery for patients undergoing laparoscopic cholecystectomy (LC). We investigated the predictive value that pre-operative neutrophil-to-lymphocyte ratio (PNLR) had on surgical outcomes.

METHODS

A review of all patients who underwent LC during a 6-year period in a single institution was performed and PNLR recorded. A PNLR cutoff value of 3 was utilised. We compared operation time, length of stay (LOS), and conversion to open between those with PNLR less and greater than 3.

RESULTS

A total of 567 patients underwent elective LC. Those with PNLR>3 had associated prolonged operation time (p < 0.005), prolonged LOS (p < 0.005), and higher rates of conversion to open surgery (p < 0.005).

CONCLUSIONS

PNLR correlates with outcomes following LC. It is useful in delineating patients that have higher risk of conversion or prolonged length of hospital stay and is helpful in assessing suitability of day-case surgery.

[Laparoscopic cholecystectomy in short-stay hospital]

AIM

To develop the protocol of surgical management of cholelithiasis in short-stay hospital.

MATERIAL AND METHODS

Surgical treatment of 161 patients with cholelithiasis was analyzed. All of them underwent elective cholecystectomy. Short-stay hospital group included 41 patients. 120 patients were operated in surgical department (group 2).

RESULTS

Incidence of intraoperative complications was 2.4% and 3.4% in both groups respectively (p>0.05). Postoperative complications were more frequent in group 2 (8.3% vs. 2.4%, p<0.05). Mean hospital-stay was 1 and 4.4 days in both groups respectively.

CONCLUSION

Treatment of chronic calculous cholecystitis is advisable in short-stay hospital. Indications for this approach and its safety in certain patients were determined. The protocol of surgical management of chronic cholecystitis in short-stay hospital was develped.

Day-case laparoscopic cholecystectomy

Objectives:

To assess the safety and feasibility of laparoscopic cholecystectomy as a day-case procedure.

Methods:

All consecutive patients who were admitted to the day-surgery unit for laparoscopic cholecystectomy at the Department of Surgery, King Saud Medical City, Riyadh, Saudi Arabia from July 2009 to June 2013 were considered for this retrospective study. The medical records were reviewed for age, gender, presenting symptoms, laboratory findings, imaging studies, American Society of Anesthesiology (ASA) grade, anesthesia, conversion to open cholecystectomy, complications, the operating surgeons, pain management, nausea, and vomiting, overnight stay, readmission, morbidity, mortality, and outpatient follow up were collected and analyzed.

Results:

A total of 487 patients underwent laparoscopic cholecystectomy as a day case (ASA I=316, ASA II=171). Surgery was performed by high surgical trainees (HSTs) (n=417) and consultants (n=70) with conversion to open cholecystectomy in 4 patients. Twenty-two (5%) patients were admitted for overnight stay for different reasons, while 465 (95%) patients were discharged before 8 pm. Two patients (0.4 %) were re-admitted to the hospital due to abdominal pain. Five patients developed umbilical port site infection (1%). A total of 443 patients were satisfied (97%), while 14 (3%) were unsatisfied. There was no mortality or intra-abdominal septic collection.

Conclusion:

Day-case laparoscopic cholecystectomy is safe and feasible with optimal patient selection, education, and planned postoperative antiemetic and analgesia management.

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.

[Morphological and functional aspects of recurrent postoperative ventral hernias]

AIM

To define the optimal treatment of postoperative ventral hernias.

MATERIAL AND METHODS

It was performed microscopic examination of intraoperative specimens which were obtained from 40 patients with medium, large and giant hernia. The aim was to reveal ultrastructural changes and morphological features which are associated with abdominal wall weakness in case of postoperative ventral hernia. There were 28 (70%) cases of primary postoperative hernia and 12 (30%) cases of recurrent and multiple-recurrent hernia. In 4 patients polypropylene mesh implants were implanted prior to recurrence. Tissue specimens were obtained from the top of herniation, hernial ring and in 6 cm from the hernial ring.

RESULTS AND DISCUSSION

Electron microscopy showed that postoperative ventral hernias are accompanied by ultrastructural destructive changes in cells of the skin, aponeurosis and muscles that indicates on morphofunctional failure of abdominal wall tissues. Swelling and degradation of collagen, fibroblasts vacuolization, capillary sludge of erythrocytes, development of vacuum zones with the fragments of altered collagen fibrils, red blood cells and mast cells are morphological signs of micronecrosis followed by abdominal wall weakness and postoperative ventral hernias.

CONCLUSION

Postoperative ventral hernias are associated with morphological and functional failure of abdominal wall due to tissue destructive changes. Therefore, this obviously defective tissue can not be used per se and especially with tension. Mesh implants should be applied.

Short-term outcomes of laparoscopic transcystic common bile duct exploration with discharge less than 24 hours

BACKGROUND

Reducing the length of stay and discharge time for patients could benefit multiple hospital units by saving money, reducing waiting time, and providing the opportunity for more patients to be treated. However, no experience of laparoscopic transcystic common bile duct exploration (LTCBDE) with discharge less than 24 hours has been reported until now. The objective of this study was to assess the feasibility and safety of LTCBDE with discharge less than 24 hours.

PATIENTS AND METHODS

A retrospective review showed that 34 of 111 patients scheduled in our institution were discharged less than 24 hours after LTCBDE between June 1 and December 31, 2011. A multimodal approach including appropriate preoperative assessment, education and counseling, early postoperative oral intake, and early mobilization was carried out. Outcomes were analyzed for patient demographics, postoperative stay, operation time, intraoperative bleeding, and reasons for failed LTCBDE.

RESULTS

Of 111 patients admitted for LTCBDE, 34 patients were discharged within 24 hours postoperatively. This study population comprised 11 males and 23 females with a mean age of 54.6±14.7 years (range, 28-79 years). The mean postoperative stay was 20.21±0.39 hours. There were no postoperative complications or deaths during the hospital stay or at the follow-up 12 months postoperatively in these 34 patients.

CONCLUSIONS

LTCBDE with discharge less than 24 hours is feasible and safe in selected patients with common bile duct stones of no more than three in number and no more than 6 mm in size. The benefit of the multimodal approach and LTCBDE may be synergistic, allowing a quick recovery of gastrointestinal function.
