Effects of different forced-air warming systems on the core temperature of patients: a manikin and multi-center clinical study

BackgroundThe use of forced-air warming (FAW) blankets is widely recognized for preventing shivering and hypothermia in patients under general anesthesia. Various types of products are currently available for hospitals, and we have conducted a preliminary evaluation of insulation equipment based on expert opinions and initial parameters. However, we lack real-world experiments and accurate clinical data to validate these parameters and the accuracy of our decision-making results. This study aims to confirm the effectiveness of different FAW systems by assessing the thermal protection and operational characteristics of the equipment in both experimental and clinical settings, thereby enhancing our evaluation database.MethodsIn the manikin test, we conducted six tests including heat distribution and heating rate, heater outlet temperature stability, etc. In the clinical study, patients were randomly assigned to four groups [Group A (Bair Hugger Therapy, 3 M, St. Paul, MN, USA; 63500); Group B (EQUATOR® level I, Smith Medical ASD, MN, USA; Snuggle Warm, SW-2013); Group C (Jiang Men Da Cheng Medical Devices Co., Ltd, China; IOB-006); and Group D (Shang Hai Nest Tech Medical Materials Co., Ltd, China; BH-017)], with each group comprising 30 individuals. At the start of anesthesia induction, the FAW blanket was activated and set to 43 °C until the completion of surgery. The primary endpoint was the average core body temperature during surgery. Secondary endpoints included hemodynamic and surgical variables, adverse events, and recovery metrics.ResultsIn the manikin test, the observed results of the experimental parameters (heat distribution, air pressure difference, and hole observation test) for Group A are superior to those of the other groups. In the clinical study, although the mean perioperative core body temperature remained above 36 °C across all groups [Group A: 36.31 ± 0.04; Group B: 36.26 ± 0.06; Group C: 36.17 ± 0.03; Group D: 36.25 ± 0.05], patients in Group A maintained higher temperatures compared to the other groups (p < 0.001).ConclusionsAmong patients undergoing laparoscopic radical resection of colorectal cancer with general anesthesia, all four FAW systems effectively prevented perioperative hypothermia. However, the system in Group A minimized heat loss more effectively than the others, providing superior thermal protection.Trial registrationChiCTR2200065394, 03/11/2022.

The effect of perioperative intravenous lidocaine infusion on postoperative sleep of elderly patients with colorectal cancer: A randomized controlled study

BackgroundPostoperative sleep disturbance (POSD) caused by postoperative pain can impede the enhanced rapid recovery of elderly patients with colorectal cancer. We propose that perioperative intravenous lidocaine infusion may enhance postoperative sleep quality by alleviating postoperative pain in elderly patients undergoing laparoscopic radical resection for colorectal cancer. MethodsSixty-three elderly patients were divided into two groups: the lidocaine group (group L) and the placebo group (group C). Patients in group L received intravenous injection of lidocaine 1.5 mg/kg during the induction of anesthesia, followed by lidocaine 1.0 mg kg−1 h−1 during surgery and for 24 h after surgery. Patients in group C received the same volume of normal saline. The primary outcome was postoperative sleep function, which was evaluated using the Athens Insomnia Scale (AIS). The secondary outcomes included the pain-at-rest and pain-on-movement of patients at 2, 4, 6, 12, 24, 48, and 72 h after surgery, opioid and propofol consumption, bowel function recovery time, postoperative complications, and lidocaine side effects. ResultsCompared to group C, AIS scores in group L were significantly lower on day 1 (12.9 ± 4.0 vs 10.6 ± 3.9, P < 0.05), day 3 (8.6 ± 4.2 vs 6.2 ± 3.9, P < 0.05), and 1 week (4.3 ± 3.1 vs 2.2 ± 2.5, P < 0.05) after surgery. There were no significant differences in VAS scores between the two groups. The intraoperative consumption of propofol and remifentanil was significantly reduced in group L. Lidocaine infusion significantly shortened the recovery time of bowel function. There were no statistical differences between the two groups regarding the incidences of PONV and postoperative pulmonary complications. No cases of local anesthetic toxicity occurred in either group. ConclusionsPerioperative intravenous administration of lidocaine can facilitate the restoration of postoperative sleep function in elderly patients undergoing laparoscopic radical resection of colorectal cancer.

Outcomes of medial to lateral vs. lateral to medial approaches in laparoscopic colorectal cancer resections.

Bowel cancer is a significant global health concern, ranking as the third most prevalent cancer worldwide. Laparoscopic resections have become a standard treatment modality for resectable colorectal cancer. This study aimed to compare the clinical and oncological outcomes of medial to lateral (ML) vs lateral to medial (LM) approaches in laparoscopic colorectal cancer resections. A retrospective cohort study was conducted at a UK district general hospital from 2015 to 2019, including 402 patients meeting specific criteria. Demographic, clinical, operative, postoperative, and oncological data were collected. Participants were categorised into LM and ML groups. The primary outcome was 30-day complications, and secondary outcomes included operative duration, length of stay, lymph node harvest, and 3-year survival. A total of 402 patients (55.7% males) were included: 102 (51.6% females) in the lateral mobilisation (LM) group and 280 (58.9% males) in the medial mobilisation (ML) group. Right hemicolectomy (n=157, 39.1%) and anterior resection (n=150, 37.3%) were the most performed procedures. The LM group had a shorter operative time for right hemicolectomy (median 165 vs. 225min, P<0.001) and anterior resection (median 230 vs. 300min, P<0.001). There was no significant difference between the two groups in terms of wound infection (P=0.443), anastomotic leak (P=0.981), postoperative ileus (P=0.596), length of stay (P=0.446), lymph node yield (P=0.848) or 3-year overall survival rate (Log-rank 0.759). The study contributes to the limited evidence on ML vs LM approaches. A shorter operative time in the LM group was noted in this study, contrary to some literature. Postoperative outcomes were comparable, with a non-significant increase in postoperative ileus in the LM group. The study emphasises the safety and feasibility of both approaches.

Comparison of clinical efficacy of different colon anastomosis methods in laparoscopic radical resection of colorectal cancer.

The objective of this study was to investigate the clinical effect of overlap anastomosis and functional end-to-end anastomosis (FEEA) in laparoscopic radical resection of colorectal cancer (CRC). The clinical data of 180 patients who underwent laparoscopic radical resection of CRC and side-to-side anastomosis were retrospectively collected; the patients were divided into the Overlap group and FEEA group, according to the anastomosis method that was used to treat them. The Overlap group had a shorter operation time, anastomosis time, post-operative hospital stay, post-operative feeding time, and post-operative exhaust time than the FEEA group (p < 0.05). The total incidence of post-operative complications was 14.4% (13/90) in the FEEA group and 0.7% (6/90) in the Overlap group, and there was no significant difference between the two groups (p > 0.05). Overlapping anastomosis can shorten the operation time and accelerate the recovery of intestinal function without increasing the incidence of post-operative complications, and it will not affect the quality of life and survival of patients in the short term after surgery.

Impact of neuromuscular block on myocardial injury after non-cardiac surgery (MINS) incidence in the early postoperative stage of older patients undergoing laparoscopic colorectal cancer resection: a randomized controlled study

BackgroundMyocardial injury after non-cardiac surgery (MINS) is a common and serious complication in older patients. This study investigates the impact of neuromuscular block on the MINS incidence and other cardiovascular complications in the early postoperative stage of older patients undergoing laparoscopic colorectal cancer resection.Methods70 older patients who underwent laparoscopic colorectal cancer resection were separated into the deep neuromuscular block group and moderate neuromuscular block group for 35 cases in each group (n = 1:1). The deep neuromuscular block group maintained train of four (TOF) = 0, post-tetanic count (PTC) 1–2, and the moderate neuromuscular block group maintained TOF = 1–2 during the operation. Sugammadex sodium was used at 2 mg/kg or 4 mg/kg for muscle relaxation antagonism at the end of surgery. The MINS incidence was the primary outcome and compared with Fisher's exact test. About the secondary outcomes, the postoperative pain was analyzed with Man-Whitney U test, the postoperative nausea and vomiting (PONV) and the incidence of cardiovascular complications were analyzed with Chi-square test, intraoperative mean artery pressure (MAP) and cardiac output (CO) ratio to baseline, length of stay and dosage of anesthetics were compared by two independent samples t-test.ResultsMINS was not observed in both groups. The highest incidence of postoperative cardiovascular complications was lower limbs deep vein thrombosis (14.3% in deep neuromuscular block group and 8.6% in moderate neuromuscular group). The numeric rating scale (NRS) score in the deep neuromuscular block group was lower than the moderate neuromuscular block group 72 h after surgery (0(1,2) vs 0(1,2), P = 0.018). The operation time in the deep neuromuscular block group was longer (356.7(107.6) vs 294.8 (80.0), min, P = 0.008), the dosage of propofol and remifentanil was less (3.4 (0.7) vs 3.8 (1.0), mg·kg−1·h−1, P = 0.043; 0.2 (0.06) vs 0.3 (0.07), μg·kg−1·min−1, P < 0.001), and the length of hospital stay was shorter than the moderate neuromuscular block group (18.4 (4.9) vs 22.0 (8.3), day, P = 0.028). The differences of other outcomes were not statistically significant.ConclusionsMaintaining different degrees of the neuromuscular block under TOF guidance did not change the MINS incidence within 7 days after surgery in older patients who underwent laparoscopic colorectal cancer resection.Trial registrationThe present study was registered in the Chinese Clinical Trial Registry (10/02/2021, ChiCTR2100043323).

Simultaneous laparoscopic colectomy and liver metastasectomy with natural orifice specimen extraction: A proof-of-concept study

Background, Natural orifice specimen extraction (NOSE) via the anus or vagina is an alternative to conventional transabdominal specimen extraction in laparoscopic colorectal cancer surgery. NOSE has been shown to be safe and effective, resulting in decreased postoperative pain, analgesia use, and improved recovery, without oncological compromise. We aimed to demonstrate the feasibility of NOSE for combined colectomy with liver metastasectomy.Methods, From July 2022 to April 2024, all cases of laparoscopic colorectal cancer resection and synchronous liver metastasectomy with NOSE were included in the study. Selection criteria included a maximum specimen diameter of less than 5 cm and patient body mass index of less than 35 kg/m2.Results, Over the 22-month duration, four consecutive patients (two males, two females) underwent combined resection with NOSE. Mean age and BMI were 74.8 (range 63–81) years and 20.9 (range 19.5–22.3) kg/m2 respectively. Patient A and D underwent anterior resection for sigmoid cancer, Patient B underwent D3 right hemicolectomy for cecal cancer, and Patient C underwent subtotal colectomy for synchronous cecal and descending colon cancer. All patients underwent liver metastasectomy at the same sitting. Patient A and D had transanal NOSE while Patients B and C underwent transvaginal NOSE. Mean operative time and blood loss was 416 (range 330–535) minutes and 338 (range 50–500) ml respectively. All patients recovered gastrointestinal function within the first two postoperative days. Infected seroma of the liver bed occurred in one patient requiring percutaneous drainage. The average maximum colon tumor diameter was 2.9 (range 1.3–4.0) cm. All resection margins were clear. Mean duration of follow-up was 7.5 (range 2–12) months.Conclusions, Simultaneous colectomy and liver metastasectomy with NOSE for colorectal cancer is feasible and safe in highly selected patients, resulting in good postoperative outcomes. This proof-of-concept analysis paves the way for larger studies to draw definitive conclusions.

Effect of Individualized PEEP Guided by Driving Pressure on Diaphragm Function in Patients Undergoing Laparoscopic Radical Resection of Colorectal Cancer: A Randomized Controlled Trial.

BACKGROUND The concept of driving pressure (ΔP) has been established to optimize mechanical ventilation-induced lung injury. However, little is known about the specific effects of setting individualized positive end-expiratory pressure (PEEP) with driving pressure guidance on patient diaphragm function. MATERIAL AND METHODS Ninety patients were randomized into 3 groups, with PEEP set to 0 in group C; 5 cmH₂O in group F; and individualized PEEP in group I, based on esophageal manometry. Diaphragm ultrasound was performed in the supine position at 6 consecutive time points from T0-T5: diaphragm excursion, end-expiratory diaphragm thickness (Tdi-ee), and diaphragm thickening fraction (DTF) were measured. Primary indicators included diaphragm excursion, Tdi-ee, and DTF at T0-T5, and the correlation between postoperative DTF and ΔP. Secondary indicators included respiratory mechanics, hemodynamic changes at intraoperative d0-d4 time points, and postoperative clinical pulmonary infection scores. RESULTS (1) Diaphragm function parameters reached the lowest point at T1 in all groups (P<0.001). (2) Compared with group C, diaphragm excursion decreased, Tdi-ee increased, and DTF was lower in groups I and F at T1-T5, with significant differences (P<0.05), but the differences between groups I and F were not significant (P>0.05). (3) DTF was significantly and positively correlated with mean intraoperative ΔP in each group at T3, and the correlation was stronger at higher levels of ΔP. CONCLUSIONS Individualized PEEP, achieved by esophageal manometry, minimizes diaphragmatic injury caused by mechanical ventilation based on lung protection, but its protection of the diaphragm during laparoscopic surgery is not superior to that of conventional ventilation strategies.

High Subcutaneous Fat Area Is an Independent Risk Factor for Parastomal Hernia after Transperitoneal Colostomy for Colorectal Cancer.

Parastomal hernia (PSH) is a common complication of colostomy; however, its risk factors remain poorly investigated. In this study, we examined the associations between sarcopenia, visceral and subcutaneous fat, and PSH in patients who underwent transperitoneal colostomy for colorectal cancer. This retrospective, single-center, cohort study included 60 patients who underwent laparoscopic or robot-assisted abdominoperineal resection or Hartmann's procedure for colorectal cancer between November 2010 and February 2022. Stoma creation was uniformly performed using the transperitoneal approach, and PSH was diagnosed via abdominal computed tomography (CT) at 1 year postoperatively. Visceral fat areas (VFAs) and subcutaneous fat areas (SFAs) were measured through preoperative CT images using an image analysis system. Risk factors for PSH were retrospectively analyzed. PSH was diagnosed in 13 (21.7%) patients. In the univariate analysis, PSH was significantly associated with body mass index >22.3 kg/m2 (p=0.002), operation time >319 min (p=0.027), estimated blood loss >230 mL (p=0.008), postoperative complications (p=0.028), stoma diameter >18.6 mm (p=0.015), VFA >89.2 cm2 (p=0.005), and SFA >173.2 cm2 (p=0.001). Multivariate analyses confirmed that SFA >173.2 cm2 (odds ratio: 16.7, 95% confidence interval 1.29-217.2, p=0.031) was an independent risk factor for PSH. Subcutaneous fat area is significantly associated with the development of PSH after transperitoneal colostomy. Applying these insights could help to prevent PSH.

Surgical and Oncological Outcome of Laparoscopic Resection of Colorectal Cancers: A Single-Center Experience.

Laparoscopy is one of the major advances in surgery in the last 30 years and has many benefits. Although laparoscopy was initially used for resection of benign colon lesions, it is now widely used for colorectal cancer resections after strong evidence has confirmed its safety and efficacy. We aim to report both the surgical and oncological outcomes of our first series of laparoscopic colorectal cancer resections. In 2013, alaparoscopic colorectal resection service was established in northern Iraq at Zheen Hospital, Erbil. Data from all consecutive colorectal cancers were collected. Patients with locally advanced diseases and those who required emergency operations for bowel obstruction or perforation were excluded. We analyzed demographic, operative, postoperative, and histopathological data for all patients who were included in the study. A total of 124 patients with colorectal cancers presented to our unit between January 2013 and January 2023. Only 112 patients fulfilled the inclusion criteria and underwent laparoscopic resections. The median age of the patients was 54.5 years. The majority of patients were men (n=62; 55.4%). In 39 patients (35%), the cancer was located in the sigmoid; in 33 patients (29.5%) the cancer was in the rectum. Laparoscopic anterior resection was the most common procedure (n=50; 45%), followed by right hemicolectomy in 17cases (15.1%). The conversion rate to open surgery was 8% (nine cases). The most common causes of conversion to open surgery were dilated bowel loops and tumour adherence to other structures. The mean operative time was 190 minutes and the mean hospital stay was three days. No complications were reported in 94patients (84%). Among the complications, wound infection was seen in sevenpatients (7.8%). There were six anastomotic leaks (6.7%). The mean number of lymph nodes harvested was 13. In 70 patients (62.5%), the lymph node count was ≥12 with a median of 13. The mean distal resection margin was 6 cm and 2.5 cm for colon and rectal resections, respectively. This study reveals that laparoscopic resection for colorectal cancers is surgically practicable and safe with the benefits of a short hospital stay, adequate resection margins, and adequate lymph node yield.

Comparison of early surgical outcomes of robotic and laparoscopic colorectal cancer resection reported by a busy district general hospital in England

Robotic platforms provide a stable tool with high-definition views and improved ergonomics compared to laparoscopic approaches. The aim of this retrospective study was to compare the intra- and short-term postoperative results of oncological resections performed robotically (RCR) and laparoscopically (LCR) at a single centre. Between February 2020 and October 2022, retrospective data on RCR were compared to LCR undertaken during the same period. Parameters compared include total operative time, length of stay (LOS), re-admission rates, 30-day morbidity. 100 RCR and 112 LCR satisfied inclusion criteria. There was no difference between the two group’s demographic and tumour characteristics. Overall, median operative time was shorter in LCR group [200 vs. 247.5 min, p < 0.005], but this advantage was not observed with pelvic and muti-quadrant resections. There was no difference in the rate of conversion [5(5%) vs. 5(4.5%), p > 0.95]. With respect to perioperative outcomes, there was no difference in the overall morbidity, or mortality between RCR and LCR, in particular requirement for blood transfusion [3(3%) vs. 5(4.5%), p 0.72], prolonged ileus [9(9%) vs. 15(13.2%), p 0.38], surgical site infections [5(4%) vs. 5(4.4%), p > 0.95], anastomotic leak [7(7%) vs. 5(4.4%), p 0.55], and re-operation rate [9(9%) vs. 7(6.3%), p 0.6]. RCR had shorter LOS by one night, but this did not reach statistical significance. No difference was observed in completeness of resection but there was a statically significant increase in lymph node harvest in the robotic series. Robotic approach to oncological colorectal resections is safe, with comparable intra- and peri-operative morbidity and mortality to laparoscopic surgery.

Transcranial Direct Current Stimulation for Anxiety During Laparoscopic Colorectal Cancer Surgery

Perioperative anxiety is prevalent among patients undergoing surgical treatment of cancer and often influences their prognosis. Transcranial direct current stimulation (tDCS) has shown potential in the treatment of various anxiety-related disorders, but data on the impact of tDCS on perioperative anxiety are limited. To evaluate the effect of tDCS in reducing perioperative anxiety among patients undergoing laparoscopic colorectal cancer (CRC) resection. This randomized clinical trial was conducted from March to August 2023 at the Affiliated Hospital of Xuzhou Medical University. Patients aged 18 years or older undergoing elective laparoscopic radical resection for CRC were randomly assigned to either the active tDCS group or the sham tDCS group. Intention-to-treat data analysis was performed in September 2023. Patients were randomly assigned to receive 2 sessions of either active tDCS or sham tDCS over the left dorsolateral prefrontal cortex on the afternoon of the day before the operation and in the morning of the day of operation. The main outcome was the incidence of perioperative anxiety from the day of the operation up to 3 days after the procedure, as measured using the Hospital Anxiety and Depression Scale-Anxiety (HADS-A) subscale (range: 0-21, with higher scores indicating more anxiety). Secondary outcomes included postoperative delirium (assessed by the Confusion Assessment Method or Confusion Assessment Method intensive care unit scale); pain (assessed by the 10-point Numeric Rating Scale [NRS], with scores ranging from 0 [no pain] to 10 [worst pain]); frailty (assessed by the Fatigue, Resistance, Ambulation, Illness and Loss of Weight [FRAIL] Index, with scores ranging from 0 [most robust] to 5 [most frail]; and sleep quality (assessed by the Pittsburgh Sleep Quality Index [PSQI], with scores ranging from 0 to 21 and higher scores indicating worse sleep quality) after the 2 sessions of the tDCS intervention. A total of 196 patients (mean [SD] age, 63.5 [11.0] years; 124 [63.3%] men) were recruited and randomly assigned to the active tDCS group (98 patients) or the sham tDCS group (98 patients). After the second tDCS intervention on the day of the operation, the incidence of perioperative anxiety was 38.8% in the active tDCS group and 70.4% in the sham tDCS group (relative risk, 0.55 [95% CI, 0.42-0.73]; P < .001). Patients in the active tDCS group vs the sham tDCS group were less likely to have postoperative delirium (8.2% vs 25.5%) and, at 3 days after the operation, had lower median (IQR) pain scores (NRS, 1.0 [1.0-1.0] vs 2.0 [2.0-2.0]), better median (IQR) sleep quality scores (PSQI, 10.5 [10.0-11.0] vs 12.0 [11.0-13.0]), and lower median (IQR) FRAIL Index (2.0 [1.0-2.0] vs 2.0 [2.0-3.0]). Findings of this randomized clinical trial indicate that administration of 2 preoperative sessions of tDCS was associated with a decreased incidence of perioperative anxiety in patients undergoing elective CRC resection. Active tDCS was also associated with better anxiety scores, pain levels, and sleep quality as well as reduced postoperative delirium and frailty. The findings suggest that tDCS may be a novel strategy for improving perioperative anxiety in patients undergoing CRC resection. Chinese Clinical Trial Register Identifier: ChiCTR2300068859.

Postoperative cognitive dysfunction in elderly patients with colorectal cancer: A randomized controlled study comparing goal-directed and conventional fluid therapy.

To investigate the impact of goal-directed fluid therapy (GDFT) on postoperative cognitive dysfunction (POCD) in elderly patients with colorectal cancer, we conducted a randomized controlled trial. Eighty elderly patients who underwent elective laparoscopic radical resection of colorectal cancer were randomly assigned to either the GDFT group or the conventional fluid therapy group. The primary outcome was the incidence of POCD during the initial 7 postoperative days, while secondary outcomes included inflammatory marker levels such as interleukin-6 (IL-6) and S100β protein, hemodynamics, level of lactic acid, postoperative functional recovery, and complications. Among 88 randomized patients, 80 were evaluable for the primary outcome. The incidence of POCD was significantly lower in the GDFT group (15.0%) compared to the conventional fluid therapy group (30.0%), with the highest occurrence observed on day 3 postoperatively in both groups (P < 0.05). IL-6 and S100β concentrations were consistently lower in the GDFT group than in the conventional fluid therapy group at the corresponding time points (P < 0.05). The GDFT group exhibited more stable perioperative hemodynamics and lower lactate levels (P < 0.05). Moreover, patients in the GDFT group exhibited better postoperative functional recovery indicators and a lower incidence of postoperative complications (P < 0.05). In summary, GDFT appears to reduce the incidence of early POCD, accelerate postoperative recovery, and enhance overall prognosis.

Erector Spinae Plane Block versus Quadratus Lumborum Block for Postoperative Analgesia after Laparoscopic Resection of Colorectal Cancer: A Prospective Randomized Study.

In recent years, the attention paid to colorectal cancer (CRC) surgery and postoperative analgesia has increased. The objective of the current study was to compare the impact of ultrasound-guided erector spinae plane block (ESPB) and transmuscular quadratus lumborum block (TQLB) upon providing relief to patients with postoperative pain who underwent laparoscopic resection for CRC. In this prospective, comparative, and randomized study, the authors considered a total of 60 patients who chose to undergo laparoscopic resection for colorectal cancer. The total number of patients was randomly divided into two groups (such as ESPB and TQLB) so that each group had a total of 30 patients. For the former group, i.e., the ESPB group, 20 ml of 0.25% bupivacaine was administered at each side for bilateral ultrasound-guided erector spinae plane block, while the latter group received the same dose of medicine for bilateral ultrasound-guided transmuscular quadratus lumborum block (TQLB). The researchers recorded the first time to rescue an analgesic, the whole amount of rescue analgesia under consumption in the first 24 hours after the surgical procedure, and associated adverse events. Among the groups considered, the ESPB group took a significantly lengthy time to raise a first request for rescue analgesic (280 ± 15.5 min) in comparison with the TQLB group (260 ± 13.8 min). Likewise, the consumption of overall nalbuphine was remarkably lesser in the ESPB group during the first 24 hours (24 ± 2.5 mg) compared to the TQLB group (30.5 ± 1.55 mg). The analgesic efficacy of ESPB was better when compared to TQLB in terms of time to rescue analgesia and overall opioid consumption during the first 24 hours. This study was registered at ClinicalTrials.gov on 10/10/2022 (registration number: NCT05574283).

The Impact of a Short Hospital Stay on Readmission Rate after Laparoscopic Colorectal Cancer Surgery under the Enhanced Recovery after Surgery Protocol

Objective: The aim of this study is to examine the safety of discharge after a one or two day hospital stay following laparoscopic colorectal cancer surgery under the enhanced recovery after surgery protocol. Methods: This retrospective study was conducted at the colorectal unit in the King Hussein Military Hospital. All patients who underwent laparoscopic resection of colorectal cancer between January 2020 and December 2023 were included and grouped according to their hospital stay: Group A had a short stay of one to two days, and Group B a stay of more than two days. Demographic information, type of surgery performed, postoperative complications, and readmission data were collected from the colorectal unit and hakeem data base. Results: Two hundred and eighty patients were included in this study: 104 patients in Group A and 176 patients in Group B. The mean age in Group A was 57.7 ± 12.82 years and in Group B 58.42 ± 13.04 years. In Group A, 46.1% were female, compared to 39.2% in Group B. The mean body mass index was similar in both groups. In Group A, 34.6% of patients were smokers, compared to 29% in Group B. The readmission rate was 9.6% in Group A and 11.4% in Group B. Conclusion: Early discharge of patient within two days following laparoscopic colorectal cancer resection is safe and was not associated with increased rates of readmission.

Pulse pressure variation guided goal-direct fluid therapy decreases postoperative complications in elderly patients undergoing laparoscopic radical resection of colorectal cancer: a randomized controlled trial

ObjectiveThe use of goal-directed fluid therapy (GDFT) has been shown to reduce complications and improve prognosis in high-risk abdominal surgery patients. However, the utilization of pulse pressure variation (PPV) guided GDFT in laparoscopic surgery remains a subject of debate. We hypothesized that utilizing PPV guidance for GDFT would optimize short-term prognosis in elderly patients undergoing laparoscopic radical resection for colorectal cancer compared to conventional fluid therapy.MethodsElderly patients undergoing laparoscopic radical resection of colorectal cancer were randomized to receive either PPV guided GDFT or conventional fluid therapy and explore whether PPV guided GDFT can optimize the short-term prognosis of elderly patients undergoing laparoscopic radical resection of colorectal cancer compared with conventional fluid therapy.ResultsThe incidence of complications was significantly lower in the PPV group compared to the control group (32.8% vs. 57.1%, P = .009). Additionally, the PPV group had a lower occurrence of gastrointestinal dysfunction (19.0% vs. 39.3%, P = .017) and postoperative pneumonia (8.6% vs. 23.2%, P = .033) than the control group.ConclusionUtilizing PPV as a monitoring index for GDFT can improve short-term prognosis in elderly patients undergoing laparoscopic radical resection of colorectal cancer.Registration numberChiCTR2300067361; date of registration: January 5, 2023.

A Multicenter Analysis of Short-term and Long-term Outcomes Following Laparoscopic Multivisceral Resection for Advanced Colorectal Cancer.

Recent research has demonstrated that laparoscopic multivisceral resection (MVR) for advanced colorectal cancer is safe, practicable, and yields satisfactory oncological results, which is in line with the growing usage of laparoscopic surgery. The effectiveness of laparoscopic MVR is still debatable, though. The goal of this study was to compare the short- and long-term results of patients with advanced colorectal cancer treated with open MVR with laparoscopic procedures. Data on 3,571 consecutive patients hospitalized at the Kyushu University National Kyushu Cancer Center for colorectal cancer surgery between 2004 and 2020 were gathered retrospectively. In the end, 84 individuals with advanced colorectal cancer who had a colectomy with MVR were examined. We evaluated invasiveness in terms of complications, blood loss, and operating time. Recurrence-free survival rates and overall 5-year survival were among the oncological outcomes. Of the 84 patients examined, 29 underwent laparoscopic treatment, and 55 underwent open treatment. The laparoscopic surgery group experienced shorter hospital stays (15 vs. 18 days, p<0.05) and much less blood loss (median volume: 167 vs. 1,058 g, p<0.005) than the open surgery group. Following the exclusion of patients with stage IV colorectal cancer from the study (groups undergoing laparoscopic surgery, n=25; open surgery, n=38), the groups displayed comparable pathologic results and no discernible variations in either the 5-year overall survival (p=0.87) or recurrence-free survival (p=0.86). In certain individuals with advanced colorectal cancer, a laparoscopic method of manipulation with MVR may be less invasive than an open method without compromising the prognosis.

Risk Factors of Acute Pain in Elderly Patients After Laparoscopic Radical Resection of Colorectal Cancer.

To investigate the risk factors of acute pain after laparoscopic radical resection of colorectal cancer (CRC) in elderly patients. Totally, 143 elderly patients (≥ 60 y old) who received laparoscopic radical resection of CRC in the People's Hospital of Xinjiang Uygur Autonomous Region from March 2021 to August 2022 were retrospectively analyzed. The patients were divided into 2 groups according to visual analog scale (VAS) scores 24 h after surgery: mild pain group (VAS score ≤ 3, n=108) and moderate to severe pain group (VAS score >3, n=35). The data of the patients, including sex, age, height, body mass, intraoperative blood loss, intraoperative urine volume, intraoperative opioid dosage, operation duration, preoperative Hospital Anxiety and Depression Scale (HADS) scores, preoperative Mini-Mental State Examination scores, VAS scores, postoperative nausea and vomiting scores were recorded. Multivariate logistic regression analysis was used to screen the risk factors of postoperative acute pain in elderly patients undergoing laparoscopic radical resection of CRC. The preoperative HADS score of the moderate to severe pain group was significantly increased compared with that of the mild pain group (10.8±2.4 vs. 6.2±1.9), as well as the operation duration (226.4±18.3 vs. 186.1±12.7), the intraoperative dosage of remifentanil (3.7±0.2 vs. 3.2±0.4), the preoperative VAS score [4(2, 7) vs. 2 (0, 4)] and postoperative VAS score [5 (4, 6) vs. 3 (2, 3)] ( P <0.05). Multivariate logistic regression analysis showed that high preoperative HADS score, long operation duration, and high preoperative VAS score ( P <0.05) were independent risk factors for acute pain after laparoscopic radical resection of CRC in elderly patients. Preoperative anxiety and depression, preoperative pain, and long operation duration are risk factors for acute pain in elderly patients after laparoscopic radical resection of CRC.

Clinical effect of laparoscopic radical resection of colorectal cancer based on propensity score matching.

The incidence of colorectal cancer (CRC) is increasing annually. Laparoscopic radical resection of CRC is a minimally invasive procedure preferred in clinical practice. To investigate the clinical effect of laparoscopic radical resection of CRC on the basis of propensity score matching (PSM). The clinical data of 100 patients who received inpatient treatment for CRC at Changde Hospital, Xiangya School of Medicine, Central South University (The First People's Hospital of Changde City) were analyzed retrospectively. The control group included patients who underwent open surgery (n = 43), and those who underwent laparoscopic surgery formed the observation group (n = 57). The baseline information of both groups was equipoised using 1 × 1 PSM. Differences in the perioperative parameters, inflammatory response, immune function, degree of pain, and physical status between the groups were analyzed. Thirty patients from both groups were successfully matched. After PSM, baseline data showed no statistically significant differences between the groups: (1) Perioperative parameters: The observation group had a longer surgery time, less intraoperative blood loss, earlier first ambulation and first anal exhaust times, and shorter gastric tube indwelling time than the control group; (2) Inflammatory response: 24 h after surgery, the levels of interleukin-6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor-α (TNF-α) between groups were higher than preoperatively. IL-6, CRP, and TNF-α levels in the observation group were lower than in the control group; (3) Immune function: At 24 h after surgery, counts of CD4-positive T-lymphocytes (CD4+) and CD4+/CD8-positive T-lymphocytes (CD8+) in both groups were lower than those before surgery, whereas CD8+ was higher than that before surgery. At 24 h after surgery, both CD4+ counts and CD4+/CD8+ in the observation group were higher than those in the control group, whereas CD8+ counts were lower; (4) Degree of pain: The visual analog scale scores in the observation group were lower than those in the control group at 24 and 72 h after surgery; and (5) Physical status: One month after surgery, the Karnofsky performance score in the observation group was higher than that in the control group. Laparoscopic radical resection of CRC has significant benefits, such as reducing postoperative pain and postoperative inflammatory response, avoiding excessive immune inhibition, and contributing to postoperative recovery.

Effect of thermal insulation on preventing hypothermia during laparoscopic radical resection for colorectal cancer.

To evaluate the effect of thermal insulation nursing in the operating room on preventing hypothermia during laparoscopic radical resection of colorectal cancer. Sixty colorectal cancer patients undergoing laparoscopic radical resection from June 2022 to August 2023 were included. The research group received thermal insulation nursing interventions using medical heaters and infusion heaters, while the control group received routine nursing measures. Clinical data including vital signs, intraoperative and postoperative complications, recovery time, nursing satisfaction, and psychological and sleep status were compared between the two groups. Thirty minutes after skin incision, both groups showed decreased body temperature, and systolic and diastolic blood pressure compared to pre-surgery levels, with no significant difference between groups (P > 0.05). However, the research group exhibited lower rates of intraoperative hypothermia, postoperative infection, and other complications, as well as shorter postoperative recovery times, hospital stays, anxiety, and depression scores compared to the control group (P < 0.05). Additionally, the research group demonstrated higher comfort scores, shorter sleep latency, longer actual sleep time, and higher nursing satisfaction rate (P < 0.05). Thermal insulation nursing intervention in the operating room during laparoscopic radical resection of colorectal cancer contributes to maintaining vital signs, preventing intraoperative hypothermia, reducing postoperative complications, expediting recovery, and improving psychological well-being and sleep quality. This intervention enhances patient comfort and nursing satisfaction in perioperative care.
