Comparative study between lateral versus latero-ventral quadratus lumborum block for perioperative analgesia in canine laparoscopic ovariectomy

OBJECTIVE

To compare the perioperative analgesic effect of lateral versus latero-ventral quadratus lumborum block (QLB) in dogs undergoing laparoscopic ovariectomy.

STUDY DESIGN

Randomized, blinded clinical study.

ANIMALS

A total of 15 client-owned female dogs undergoing laparoscopic ovariectomy.

METHODS

Animals were randomly assigned to receive a bilateral QLB, performed with 0.3 mL kg-1 ropivacaine 0.5%, either with lateral (group LQLB, n = 7) or latero-ventral approach (group LVQLB, n = 7). Dogs were premedicated intramuscularly with methadone 0.2 mg kg-1 and dexmedetomidine 3 μg kg-1. General anaesthesia was induced intravenously (IV) with propofol and maintained with isoflurane. Cardiovascular and respiratory variables were continuously monitored and recorded every 5 minutes during surgery. Fentanyl 3 μg kg-1 was administered IV if there was a 20% increase in heart rate and/or mean arterial pressure from previous values recorded 5 minutes before. Meloxicam 0.2 mg kg-1 was administered IV to all dogs during recovery. The short-form of the Glasgow Composite Pain Scale was used hourly for 8 hours post-QLB. Methadone 0.2 mg kg-1 was administered IV when pain score was ≥ 6/24. A chi-square test compared the number of dogs requiring intraoperative rescue fentanyl. A Friedman test with a Dunn's post hoc was used to evaluate the trend in postoperative pain scores within each group, and a Mann-Whitney U test compared scores between the groups at each time point; p < 0.05.

RESULTS

Significantly fewer dogs required intraoperative rescue fentanyl in group LQLB than in group LVQLB. No dog required postoperative rescue methadone, and there were no significant differences in pain scores.

CONCLUSIONS AND CLINICAL RELEVANCE

Bilateral QLB performed with lateral approach reduced the number of dogs requiring intraoperative rescue analgesia in comparison with the latero-ventral approach. No differences were detected postoperatively, possibly owing to the confounding effects of methadone, dexmedetomidine and meloxicam.

Long-term outcomes of single-port laparoscopic hepatectomy for hepatocellular carcinoma: a retrospective comparative analysis

Purpose

Numerous efforts have been made to achieve minimally invasive surgery, such as single-port laparoscopic surgery. However, few studies have provided long-term follow-up information, and the number of patients with hepatocellular carcinoma (HCC) in previous studies has been small. The purpose in this study is to compare the long-term oncological outcomes of HCC patients who underwent single-port laparoscopic hepatectomy (SPLH) with those of patients who underwent multiport laparoscopic hepatectomy (MPLH).

Methods

We retrospectively reviewed the medical records of 135 patients with HCC who underwent laparoscopic liver between January 2008 and December 2018. Of the 135 patients, 53 underwent MPLH, and 82 underwent SPLH.

Results

From January 2008 to December 2018, 135 patients underwent laparoscopic hepatectomy for HCC. Among them, 82 patients underwent SPLH, and 53 patients underwent MPLH. Neither long-term overall survival (P = 0.849) nor recurrence-free survival (P = 0.057) differed significantly between the 2 groups, even though the recurrence rate was higher in the SPLH group. In the univariable analysis of risk factors for recurrence, multiple tumors, SPLH method, and portal vein invasion were statistically significant (P < 0.05). Multivariable analysis showed that the SPLH method and portal vein invasion were independent adverse prognostic factors for recurrence-free survival.

Conclusion

In terms of both short-term and long-term outcomes, the SPLH method seems to be a feasible approach for HCC in select patients. Because the potential risk of margin recurrence might produce poor oncological outcomes, strict patient selection is essential to ensure that an adequate safety margin can be secured.

Comparative Analysis of Laparoscopic Versus Open Procedures in Specific General Surgical Interventions

Laparoscopic and open surgeries are two distinct surgical approaches with significantly different procedures and outcomes. Minimally invasive surgery, also known as laparoscopic surgery, utilizes small incisions and specialized instruments like the laparoscope to perform procedures. This contrasts with open surgery, which requires larger incisions to directly access the surgical site. Open surgery was the preferred approach for any invasive procedure until the introduction of new technological advances in the form of laparoscopy. While laparoscopy is still evolving, preliminary results demonstrate promise for various operations. Open surgery provides the healthcare professional with more liberty in the form of increased visualization, but it also increases tissue damage and hospital stays. Laparoscopic and open procedures are both valuable surgical methods with advantages and disadvantages. While open surgery is favored for difficult patients, laparoscopic surgery offers a quicker recovery and fewer scars. The choice between the two approaches depends on the patient's condition, surgical demands, and the surgeon's skills. As these methods develop, they become increasingly important for offering safe and efficient surgical treatments across a range of medical specialties.

The role of laparoscopy in closed abdominal injury

Objective

To investigate the effect of laparoscopy on the diagnosis and treatment of closed abdominal injury.

Methods

A total of 26 patients with closed abdominal injury admitted to our hospital from January 2016 to January 2019 were searched. All patients were treated by laparoscopy. All patient reports were made with the informed consent of the patients.

Results

All patients were diagnosed clearly during operation. Among them, there were 3 cases of gastric perforation, 2 cases of liver rupture, 13 cases of spleen rupture, 3 cases of small intestine rupture, 1 case of liver round ligament laceration, 2 cases of small mesenteric vascular laceration, 1 case of colon liver mesenteric laceration, and 1 case of retroperitoneal hematoma. Of the 26 patients in this group, 23 (88.5%) completed laparoscopically or laparoscopically assisted; 5 cases (19.3%) only performed laparoscopic exploration without special treatment, and 3 cases (11.5%) switched to laparotomy. The blood loss was 50-2000 ml (mean 500 ml), and the operative time was 60-180min (mean 128min). The length of hospital stay was 3-21 d (mean 9 d). There were no complications or deaths related to laparoscopy in the whole group. Conclusion Laparoscopic technique has the advantages of less trauma, high diagnosis rate and fast recovery. It can also be used for surgical treatment in the diagnosis and treatment of closed abdominal injury, so as to achieve the purpose of comprehensive diagnosis and treatment. The limitations of laparoscopy should also be noted.

Using complete blood count-derived inflammatory markers to compare postoperative inflammation in dogs undergoing open or laparoscopic ovariectomy

BACKGROUND

The inflammatory response triggered in dogs after laparoscopic ovariectomy (LapOV) or ovariectomy through mini-celiotomy (COV) has never been compared using the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and systemic inflammatory index (SII).

METHODS

Bitches underwent LapOV (n = 25) or COV (n = 25). NLR, PLR and SII were calculated 1 hour before ovariectomy (T0) and 2-3, 6-8 and 20-24 hours (T1-T3) after surgery.

RESULTS

Surgical time was longer in the LapOV group. Changes over time were observed in the NLR, PLR and SII in both groups (p < 0.001). PLR at baseline and T1 (p = 0.03 and 0.01) and NLR, PLR and SII at T2 (p = 0.01, 0.01 and 0.009) were higher in the LapOV group than in the COV group, but they did not differ at T3.

LIMITATIONS

The overrepresentation of Greyhounds in the LapOV group and the short-term follow-up are the study's main limitations.

CONCLUSION

Although an inflammatory peak was observed 6-8 hours after COV or LapOV, it was higher after the laparoscopy. However, there was no difference in the bitches' inflammatory status 24 hours after surgery.

Comparison of clinical efficacy of single-incision and traditional laparoscopic surgery for colorectal cancer: A meta-analysis of randomized controlled trials and propensity-score matched studies

Background

Single-incision laparoscopy surgery (SILS) is a new laparoscopic technique that has emerged in the past decade. Whether it has advantages over conventionl laparoscopy surgery (CLS) is inconclusive. This article aimed to compare the short- and long-term outcomes of single-incision laparoscopic surgery and conventional laparoscopic surgery for colorectal cancer through high-quality literature text mining and meta-analysis.

Methods

Relevant articles were searched on the PubMed, Embase, and Cochrane Library databases from January 2012 to November 2021. All data was from randomized controlled trials (RCTs) in order to increase the confidence of the analytical results.The main outcomes were intraoperative and postoperative complications.

Results

A total of 10 RCTs were included, involving 1609 patients. The quality of the included studies was generally high. No significant difference was found between SILS and CLS in the postoperative complications, operation time, postoperative hospital stay, number of lymph nodes removed, readmission, reoperation, complication level I- II, complication level IIIa, complication level IIIb, prolonged Ileus, blood loss, infection, anastomotic leakage and operation time. The results showed that SILS group had a higher rate of intraoperative complications, but it had lower incision length and better cosmetic effects.

Conclusion

These results indicate that SILS did not have a comprehensive and obvious advantage over the CLS. On the contrary, SILS has higher intraoperative complications, which may be related to the more difficulty of SILS operation, but SILS still has better cosmetic effects, which is in line with the concept of surgical development. Therefore, the SILS needs to be selected in patients with higher cosmetic requirements and performed by more experienced surgeons.

Application of multimodal identification technology in the innovative management operation department

Background

The optimization of surgical procedures and the management of surgical quality and safety have become the focus of attention of hospital managers. The application of multimodal identification technology in the innovative management mode of hospital operating department has made remarkable progress.

Methods

To investigate the effect of the upgraded multimodal identification technology on the innovative management of the operating department, 2,280 cases of laparoscopic surgery using traditional surgical management procedures from January to December 2019 before the management upgrade were set as the control group, and 2,350 laparoscopic surgeries with the upgraded multimodal identification management process from January to December 2020 were selected as the experimental group. The operating efficiency, material management efficiency, and patient experience and satisfaction of the two groups were investigated and compared.

Results

Compared with traditional procedures, the upgraded multimodal surgical management system significantly improves the efficiency of laparoscopic surgery and reduces surgical consumption and costs. In addition, the multimodal surgical information identification system significantly improves the surgical experience for patients undergoing laparoscopic surgery.

Conclusion

Application of multimodal identification technology improves the innovative management of operation department compared with traditional surgery management procedure.

The Comparison of Life Quality between Ultrasound-Guided High-Intensity Focused Ultrasound and Laparoscopic Myomectomy for the Treatment of Uterine Fibroids

Objective

This study is aimed at comparing the uterine fibroids patients' postoperative living quality between ultrasound-guided high-intensity focused ultrasound (HIFU) and laparoscopic myomectomy.

Materials and Methods

A total of 164 patients were included with uterine fibroids who underwent laparoscopic myomectomy and HIFU in Cangzhou Central Hospital from September 2020 to November 2021. This study divided these objects into HIFU group and laparoscopic group, and both groups were followed up 6 months after surgery. After obtaining the results, Uterine Fibroid Symptom and health-related Quality Of Life questionnaire (UFS-QOL) and 36-Item Short Form Health Survey (SF-36) were performed before and after treatment to assess patient outcome.

Results

After treatments, the living quality in both groups was significantly improved compared with that before surgery, which had statistical significant (P < 0.05). After treatment, the scores of the two scales in HIFU group were significantly better than those in the laparoscopic group (P < 0.05).

Conclusion

In comparison with laparoscopic myomectomy, ultrasound-guided high-intensity focused ultrasound could improve the life quality of patients more effectively than traditional laparoscopic myomectomy and was helpful to the recovery and prognosis of uterine fibroids after treatment. The outcomes will provide a reference for clinicians to select a more appropriate treatment for uterine fibroids.

Pet-owner perceptions of laparoscopy in an urban hybrid veterinary practice

OBJECTIVE

To investigate owner perceptions of laparoscopic surgery, including attitudes towards paying more for minimally invasive surgery (MIS).

STUDY DESIGN

Randomized cross-sectional prospective survey.

SAMPLE POPULATION

One hundred owners presenting at a combined general and specialty practice.

METHODS

Participants were interviewed using a survey tool to assess prior knowledge of laparoscopic procedures, attitude for or against these procedures, reasons for this attitude, and whether they would pay more for these procedures. Demographic data were collected.

RESULTS

Fifty-five percent of owners had previous knowledge of laparoscopy. Ninety-two percent of owners would choose laparoscopy over an open procedure for their pet. Reasons given for preferring laparoscopy: less postoperative pain (66.3%), shorter length of hospitalization (26.1%), better cosmesis (20.1%), perception of lower cost (15.2%), faster return to function (14.1%), length of anesthesia (5.4%), and other reasons (26.1%). Ninety-one percent of owners were willing to pay more for MIS. Among owners who indicated they would be willing to pay more, owners presenting with dogs were 2.5 times more likely to be willing to pay at least $1000 more than owners presenting with cats.

CONCLUSION

The majority of owners surveyed at a large hybrid hospital in an urban setting choose laparoscopic over open procedures and are willing to pay more for them.

CLINICAL SIGNIFICANCE

The results highlight the importance of client and veterinarian education regarding the options of MIS for pets, as owners who are informed may prefer referral for these procedures. The financial investment to build a MIS practice may be justified.

Impact of intravenous dexmedetomidine on postoperative bowel movement recovery after laparoscopic nephrectomy: A consort-prospective, randomized, controlled trial

BACKGROUND

Postoperative ileus is a frequent postoperative complication, especially after abdominal surgery. Sympathetic excitation is the primary factor for postoperative ileus. Sympathetic activation becomes increased by surgical stress, postoperative pain, and inflammation. Dexmedetomidine (DEX) can inhibit sympathetic nerve activity, inflammation, and pain.

AIM

To observe whether DEX promotes bowel movements in patients after laparoscopic nephrectomy.

METHODS

One hundred and twenty patients undergoing laparoscopic nephrectomy were assigned to three groups: C (normal saline infusion), D1 (DEX 0.02 µg/kg/h), and D2 (DEX 0.04 µg/kg/h). The primary outcomes were the recorded times to first flatus, defecation, and eating after surgery. The secondary outcomes were postoperative pain, assessed using the numerical rating scale (NRS), adverse effects, and the duration of the postoperative hospital stay.

RESULTS

The times to first flatus, defecation, and eating in groups D1 and D2 were significantly shorter than those in group C (P < 0.01). The NRS scores at 8 h and 24 h after surgery were significantly lower in groups D1 and D2 than in group C (P < 0.05). No adverse effects were observed (P > 0.05).

CONCLUSION

Postoperative infusion of DEX at 0.04 µg/kg/h facilitates bowel movements in patients undergoing laparoscopic nephrectomy.

Single-Incision vs. Conventional Laparoscopic Surgery for Colorectal Cancer: An Update of a Systematic Review and Meta-Analysis

Background: Although the advantages of single-incision laparoscopic surgery have been reported in several meta-analyses, the low quality of studies included in the meta-analyses limits the reliability of such a conclusion. In recent years, the number of randomized controlled trials on the efficacy of SILS in colorectal cancer has been on the rise. This update systematic review and meta-analysis of RCTs aims to compare efficacy and safety of SILS and CLS in the patients with colorectal cancer. Methods: Relevant data was searched on the CNKI, Wanfang, VIP, Sinomed, PubMed, Embase, and Cochrane CENTRAL databases from inception until February 5th, 2021. All RCTs comparing SILS and CLS were included. The main outcomes were 30 days of mortality, postoperative complications, intraoperative complications, whereas secondary outcomes were the number of lymph nodes removed, duration of hospital stay, intraoperative blood loss, abdominal incision length, reoperation, readmission, conversion to laparotomy, operation time and anastomotic leakage. Results: A total of 10 RCTs were included, involving 1,133 participants. The quality of the included studies was generally high. No significant difference was found between SILS and CLS in the 30 days mortality rate. The results showed that SILS group had a lower rate of postoperative complications (RR = 0.67, 95% CI: 0.49-0.92), higher rate of intraoperative complications (RR = 2.26, 95%CI: 1.00-5.10), shorter length of abdominal incision (MD = -2.01, 95% CI:-2.42-1.61) (cm), longer operation time (MD = 11.90, 95% CI: 5.37-18.43) (minutes), shorter hospital stay (MD = -1.12, 95% CI: -1.89-0.34) (days) compared with CLS group. However, intraoperative blood loss (MD = -8.23, 95% CI: -16.75-0.29) (mL), number of lymph nodes removed (MD = -0.17, 95% CI: -0.79-0.45), conversion to laparotomy (RR=1.31, 95% CI: 0.48-3.60), reoperation (RR = 1.00, 95% CI: 0.30-3.33) and readmission (RR =1.15, 95% CI: 0.12-10.83) and anastomotic leakage were not significantly different between the two groups. Conclusion: These results indicate that SILS did not has a comprehensive and obvious advantage over the CLS. Surgeons and patients should carefully weigh the pros and cons of the two surgical procedures. Further RCTs are needed to prove long-term outcomes of SILS in colorectal cancer.

Single Incision Laparoscopic Surgery (SILS) in Small Animals: A Systematic Review and Meta-Analysis of Current Veterinary Literature

In veterinary surgery, single incision laparoscopic surgery (SILS) techniques have been described since 2009, and, in recent decades, many authors have reported the application of SILS in small animals, thus, promoting the wide dissemination of this novel approach among veterinary laparoscopists. The aim of this literature review is to provide a critical evaluation of the scientific reports on SILS in the field of small animal laparoscopic surgery. A comprehensive literature review was performed including from 1 January 2009 to 1 July 2020. The following data were recorded from each study: the design, year of publication, surgical procedure, species, number of animals included, and surgical time. The type of SILS technique and type of control group technique were evaluated. In total, 90 articles were identified through database searches and manual searches. The qualitative analysis showed that most of the articles were retrospective studies, without a control group or case series. A meta-analysis was performed on the eight controlled studies, showing that SILS ovariectomy and gastrointestinal procedures had a comparable surgical time to multiport techniques. The study of the articles available in the veterinary literature did not allow for an adequate meta-analysis of the published results, especially regarding post-operative pain, evaluations of surgical times, and post-operative complications in comparison to multiport techniques. Therefore, veterinary surgeons who want to employ these techniques must consider the real advantages of SILS techniques.

Evaluation of pet owner preferences for operative sterilization techniques in female dogs within the veterinary community

OBJECTIVE

To describe pet owner preferences within the veterinary community when choosing operative techniques for canine spay.

STUDY DESIGN

Prospective survey.

SAMPLE POPULATION

1234 respondents from 5 veterinary university teaching hospitals in North America.

METHODS

An electronic survey was distributed to faculty, students, and staff that currently are or previously were dog owners. Responses were analyzed to determine what spay technique respondents would choose for their own dogs. Surgical options offered included open celiotomy, 2-port (TP) laparoscopy, single-port (SP) laparoscopy, and natural orifice transluminal endoscopic surgery (NOTES).

RESULTS

TP laparoscopic ovariectomy (OVE) was the most popular choice, followed by SP laparoscopic OVE; NOTES was the least popular technique when all surgical options were available. If only minimally invasive surgeries were offered, 0.3% of respondents would refuse surgery. Nearly half (48%) of respondents were willing to spend between $100 and $200 more for a minimally invasive OVE than for an open celiotomy.

CONCLUSION

Minimally invasive OVE is an acceptable operative approach to those in the veterinary community. Additional study is required to correlate these findings with the general veterinary client population.
