Effect of the alveolar recruitment maneuver during laparoscopic colorectal surgery on postoperative pulmonary complications: A randomized controlled trial.

Intraoperative lung-protective ventilation, including low tidal volume and positive end-expiratory pressure, reduces postoperative pulmonary complications. However, the effect and specific alveolar recruitment maneuver method are controversial. We investigated whether the intraoperative intermittent recruitment maneuver further reduced postoperative pulmonary complications while using a lung-protective ventilation strategy. Adult patients undergoing elective laparoscopic colorectal surgery were randomly allocated to the recruitment or control groups. Intraoperative ventilation was adjusted to maintain a tidal volume of 6-8 mL kg-1 and positive end-expiratory pressure of 5 cmH2O in both groups. The alveolar recruitment maneuver was applied at three time points (at the start and end of the pneumoperitoneum, and immediately before extubation) by maintaining a continuous pressure of 30 cmH2O for 30 s in the recruitment group. Clinical and radiological evidence of postoperative pulmonary complications was investigated within 7 days postoperatively. A total of 125 patients were included in the analysis. The overall incidence of postoperative pulmonary complications was not significantly different between the recruitment and control groups (28.1% vs. 31.1%, P = 0.711), while the mean ±â€…standard deviation intraoperative peak inspiratory pressure was significantly lower in the recruitment group (10.7 ±â€…3.2 vs. 13.5 ±â€…3.0 cmH2O at the time of CO2 gas-out, P < 0.001; 9.8 ±â€…2.3 vs. 12.5 ±â€…3.0 cmH2O at the time of recovery, P < 0.001). The alveolar recruitment maneuver with a pressure of 30 cmH2O for 30 s did not further reduce postoperative pulmonary complications when a low tidal volume and 5 cmH2O positive end-expiratory pressure were applied to patients undergoing laparoscopic colorectal surgery and was not associated with any significant adverse events. However, the alveolar recruitment maneuver significantly reduced intraoperative peak inspiratory pressure. Further study is needed to validate the beneficial effect of the alveolar recruitment maneuver in patients at increased risk of postoperative pulmonary complications.

Perceptions of theatre team members to robotic assisted surgery and the aid of technology in colorectal surgery.

The implementation of robotic assisted surgery (RAS) has brought in a change to the perception and roles of theatre staff, as well as the dynamics of the operative environment and team. This study aims to identify and describe current perceptions of theatre staff in the context of RAS. 12 semi-structured interviews were conducted in a tertiary level university hospital, where RAS is utilised in selected elective settings. Interviews were conducted by an experienced research nurse to staff of the colorectal department operating theatre (nursing, surgical and anaesthetics) with some experience in operating within open, laparoscopic and RAS surgical settings. Thematic analysis on all interviews was performed, with formation of preliminary themes. Respondents all discussed advantages of all modes of operating. All respondents appreciated the benefits of minimally invasive surgery, in the reduced physiological insult to patients. However, interviewees remarked on the current perceived limitations of RAS in terms of logistics. Some voiced apprehension and anxieties about the safety if an operation needs to be converted to open. An overarching theme with participants of all levels and backgrounds was the 'Teamwork' and the concept of the [robotic] team. The physical differences of RAS changes the traditional methods of communication, with the loss of face-to-face contact and the physical 'separation' of the surgeon from the rest of the operating team impacting theatre dynamics. It is vital to understand the staff cultures, concerns and perception to the use of this relatively new technology in colorectal surgery.

[Impact of obesity on the incidence of postoperative pulmonary complications following laparoscopic colorectal surgery].

Objective: To evaluate the effects of obesity on the incidence of postoperative pulmonary complications (PPCs) following laparoscopic colorectal surgery. Methods: A total of 150 patients with pathological diagnosis of colorectal cancer who accepted laparoscopic colorectal excision from January to May 2023 were retrospectively recruited. All the patients scored 26 points or more in the Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) model, making them all in intermediate to high risks of PPCs. Patients were divided into obesity group and non-obesity group depending on whether they were obese or not. Propensity score matching (1∶1) was performed to achieve the balance of clinicopathological characteristics with the matching factors of age, sex, respiratory complications and ARISCAT score. A total of 96 patients were eventually enrolled, with 48 patients in obesity group and 48 patients in non-obesity group. Besides, the patients were divided into 25°-30° Trendelenburg subgroup and ±10°-15° Trendelenburg subgroup according to surgical sites for further analysis. The incidence of PPCs, the intraoperative airway pressure and blood biomarker expression of lung injury, including soluble receptor for advanced glycation end products (sRAGE) and angiopoietin-2 (ANG2) at postoperative day (POD) 1 and POD3 between the two groups were compared. The relationship between obesity and incidence of PPCs within 30 postoperative days were analyzed with unifactorial Cox proportional hazard model. Results: The obesity group was comprised of 35 males and 13 females with a median age of 60 (49, 69) years, and the non-obesity group was comprised of 35 males and 13 females with a median age of 60 (52, 67) years. The incidence of PPCs was 50.0% (24/48) in the obesity group, which was higher than 20.8% (10/48) in the non-obesity group and the incidence of grade Ⅰ PPCs and microatelectasis were 31.3% (15/48) and 33.3% (16/48), higher than the 12.5% (6/48) and 12.5% (6/48) of the non-obesity group (all P<0.05). The peak airway pressure (Ppeak) and plateau airway pressure (Pplat) of patients in obesity group were 34.0(31.5, 36.5) and 30.0(27.0, 32.0) cmH2O(1 cmH2O=0.098 kPa), which were significantly higher than the 26.0 (24.0, 29.5) and 22.0 (21.0, 26.5) cmH2O of the non-obesity group (all P<0.001). The ANG2 level of the obesity group at POD3 was 11.9 (8.4, 16.5) µg/L, which was higher than 9.2 (6.0, 12.3) µg/L of the non-obesity group (P=0.045). In 25°-30°Trendelenburg subgroup, the incidence of PPCs in obese patients were significantly higher than that of non-obese patients [41.4% (12/29) vs 11.4% (4/35), P=0.005]. In ±10°-15°Trendelenburg subgroup, no significant difference was found in PPCs incidence between obese and non-obese patients [63.2% (12/19) vs 46.2% (6/13), P=0.215]. The unifactorial Cox proportional hazard model analysis showed that obesity was a risk factor of PPCs in 30 postoperative days (HR=3.015, 95%CI: 1.438-6.321, P=0.001). Conclusion: In patients undergoing laparoscopic colorectal surgery with intermediate to high risk of PPCs, obesity raises intraoperative airway pressure and aggravates intraoperative lung endothelial injury. Obesity is a risk factor of PPCs in 30 postoperative days.

Resultados de una encuesta nacional sobre el manejo de los pacientes diagnosticados de diverticulitis aguda no complicada / Results of a national survey about the management of patients with acute uncomplicated diverticulitis

Introducción: El manejo de los pacientes diagnosticados de diverticulitis aguda no complicada ha evolucionado en los últimos años, y según diversas guías clínicas internacionales actuales, el tratamiento ambulatorio y sin antibioterapia puede ser utilizado en pacientes seleccionados. El objetivo de este estudio es evaluar la adhesión de los distintos centros nacionales a estas y otras recomendaciones en esta enfermedad. Métodos: Se realizó una encuesta online a nivel nacional que se dio a conocer a través de diversas aplicaciones informáticas y se analizaron estadísticamente los resultados obtenidos. Resultados: Participaron 104 cirujanos, representando 69 centros hospitalarios nacionales. En el 82,6% de los centros, se realiza manejo ambulatorio de los pacientes diagnosticados de diverticulitis aguda no complicada. El 23,2% de los centros tiene implantado un protocolo de tratamiento sin antibioterapia en pacientes seleccionados, mientras que en los centros que no siguen estas recomendaciones, las razones principales son las dificultades logísticas para su desarrollo (49,3%) y la ausencia de evidencia actual para ello (44,8%). Se han encontrado diferencias estadísticamente significativas al comparar la implantación de dichos protocolos entre centros con unidades acreditadas avanzadas y aquellas que no, con mayores tasas de manejo ambulatorio y sin antibioterapia en los centros acreditados avanzados (p≤0,05). Conclusiones: A pesar de ser una enfermedad muy frecuente, existe mucha heterogeneidad en su tratamiento a nivel nacional, por lo que sería recomendable la unificación de criterios diagnósticos y de tratamiento mediante la colaboración de las sociedades científicas y la simplificación de la puesta en marcha de protocolos hospitalarios.(AU)

Introduction: Management of patients diagnosed of acute uncomplicated diverticulitis has evolved lately and according to the latest guidelines, outpatient treatment and management without antibiotherapy may be used in selected patients. The aim of this study is to evaluate the adhesion among national centres to these and others recommendations related to this pathology. Methods: An online national survey, that has been broadcast by several applications, was performed. The results obtained were statistically analysed. Results: A total of 104 surgeons participated, representing 69 national hospitals. Of those, in 82.6% of the centers, outpatient management is performed for acute uncomplicated diverticulitis. 23.2% of the hospitals have a protocol stablished for treatment without antibiotherapy in selected patients. Centers that do not follow these protocols allege that the mean reasons are the logistic difficulties to set them up (49.3%) and the lack of current evidence for it (44.8%). Significative statistical differences have been found when comparing the establishment of such protocols between centers with advanced accredited units and those who are not, with higher rates of outpatient management and treatment without antibiotics in accredited units (P≤.05). Conclusions: In spite that this a very common disease, there is a huge national heterogeneity in its treatment. This is why it would adviseable to unify diagnostic and treatment criteria by the collaboration of scientific societies and the simplification of the development of hospitalary protocols.(AU)

Ultrasound-guided stellate ganglion block benefits the postoperative recovery of patients undergoing laparoscopic colorectal surgery: a single-center, double-blinded, randomized controlled clinical trial.

BACKGROUND: With the increasing prevalence of colorectal cancer (CRC), optimizing perioperative management is of paramount importance. This study investigates the potential of stellate ganglion block (SGB), known for its stress response-mediating effects, in improving postoperative recovery. We postulate that preoperative SGB may enhance the postoperative recovery of patients undergoing laparoscopic CRC surgery. METHODS: We conducted a randomized controlled trial of 57 patients undergoing laparoscopic colorectal cancer surgery at a single center. Patients, aged 18-70 years, were randomly assigned to receive either preoperative SGB or standard care. SGB group patients received 10 mL of 0.2% ropivacaine under ultrasound guidance prior to surgery. Primary outcome was time to flatus, with secondary outcomes encompassing time to defecation, lying in bed time, visual analog scale (VAS) pain score, hospital stays, patient costs, intraoperative and postoperative complications, and 3-year mortality. A per-protocol analysis was used. RESULTS: Twenty-nine patients in the SGB group and 28 patients in the control group were analyzed. The SGB group exhibited a significantly shorter time to flatus (mean [SD] hour, 20.52 [9.18] vs. 27.93 [11.69]; p = 0.012), accompanied by decreased plasma cortisol levels (mean [SD], postoperatively, 4.01 [3.42] vs 7.75 [3.13], p = 0.02). Notably, postoperative pain was effectively managed, evident by lower VAS scores at 6 h post-surgery in SGB-treated patients (mean [SD], 4.70 [0.91] vs 5.35 [1.32]; p = 0.040). Furthermore, patients in the SGB group experienced reduced hospital stay length (mean [SD], day, 6.61 [1.57] vs 8.72 [5.13], p = 0.042). CONCLUSIONS: Preoperative SGB emerges as a promising approach to enhance the postoperative recovery of patients undergoing laparoscopic CRC surgery.

[Prospects of qualitative and quantitative assessment of bowel perfusion by fluorescent angiography with indocyanine green in colorectal surgery. First experience]. / Perspektivy kachestvennoi i kolichestvennoi otsenki perfuzii kishki metodom flyuorestsentnoi angiografii s indotsianinom zelenym v kolorektal'noi khirurgii. Pervyi opyt.

OBJECTIVE: To assess the possibilities of fluorescent detection system in qualitative and quantitative assessment of bowel perfusion in colorectal resections. MATERIAL AND METHODS: From May to August 2023, a single-center pilot cross-sectional unblinded study with inclusion of 18 patients with colon cancer (of left-sided - 12, of right-sided - 6, mean age - 72.9 years, m/w - 61/39%) was conducted. All patients underwent laparoscopic colorectal resections with extracorporeal stage of bowel transection. The evaluation of the bowel's ICG perfusion was conducted to assist in decision making about the level of its resection. Qualitative (visual) assessment was carried out in all 18 patients, in one patient twice, quantitative assessment of perfusion was conducted in 8 patients (left-sided resections - 6, right-sided hemicolectomy - 2). The qualitative evaluation was performed in real time on the analysis of the color gradient. The time parameters and fluorescence intensity at different level proximally and distally from the resection line were quantitatively estimated: Tstart - time of occurrence of minimal fluorescence in the areas of interest after the ICG injection (sec); Tmax - time to achieve maximum fluorescence intensity after the ICG injection (sec); Tmax-start - time interval between Tstart and Tmax, Imax - level of maximum fluorescence intensity (I). RESULTS: Visual qualitative analysis of fluorescence revealed unsatisfactory perfusion characteristics (black, dark-gray color) in the area planned by the surgeon to anastomose the bowel in 3 of 18 patients (16.6%). When analyzing the quantitative data of this group of patients, there was a 2-6-fold decrease in Imax level, and one patient had an increase in Tmax-start at the level of intended resection compared to the bowel's sections in the favorable zone. In all cases, the final bowel transection was conducted in the area of good perfusion. There was no clinical evidence of anastomotic dehiscence in the study group. CONCLUSION: Intraoperative evaluation of bowel perfusion is an important component of safe anastomosis formation in colorectal surgery. The use of ICG-FA allows to conduct qualitative and quantitative assessment of tissue perfusion of the bowel in order to assist in making intraoperative decisions. Quantitative evaluation of fluorescence provides more objective information about perfusion parameters. Imax and Tmax-start are the most promising quantitative indicators of local bowel's perfusion. Nevertheless, the precise interpretation of the quantitative indicators of ICG perfusion needs to be clarified.

A systematic review and meta-analysis of short-term outcomes comparing the efficacy of robotic versus laparoscopic colorectal surgery in obese patients.

This meta-analysis was conducted to evaluate and contrast the effectiveness of robotic-assisted and laparoscopic colorectal surgery in the treatment of obese patients. In February 2024, we carried out an exhaustive search of key global databases including PubMed, Embase, and Google Scholar, limiting our focus to studies published in English and Chinese. We excluded reviews, protocols lacking published results, articles derived solely from conference abstracts, and studies not relevant to our research objectives. To analyze categorical variables, we utilized the Cochran-Mantel-Haenszel method along with random-effects models, calculating inverse variances and presenting the outcomes as odds ratios (ORs) along with their 95% confidence intervals (CIs). Statistical significance was determined when p values were less than 0.05. In our final meta-analysis, we included eight cohort studies, encompassing a total of 5,004 patients. When comparing the robotic surgery group to the laparoscopic group, the findings revealed that the robotic group experienced a longer operative time (weighted mean difference (WMD) = 37.53 min, 95% (CI) 15.58-59.47; p = 0.0008), a shorter hospital stay (WMD = -0.68 days, 95% CI -1.25 to -0.10; p = 0.02), and reduced blood loss (WMD = -49.23 mL, 95% CI -64.31 to -34.14; p < 0.00001). No significant differences were observed between the two groups regarding overall complications, conversion rates, surgical site infections, readmission rates, lymph node yield, anastomotic leakage, and intestinal obstruction. The results of our study indicate that robot-assisted colorectal surgery offers benefits for obese patients by shortening the length of hospital stay and minimizing blood loss when compared to laparoscopic surgery. Nonetheless, it is associated with longer operation times and shows no significant difference in terms of overall complications, conversion rates, rehospitalization rates, and other similar metrics.

[The effect of deep neuromuscular block combined with low pneumoperitoneum pressure on postoperative pain in patients undergoing laparoscopic radical colorectal surgery].

Objective: To investigate the effect of deep neuromuscular blockade (DNMB) combined with low pneumoperitoneum pressure anesthesia strategy on postoperative pain in patients undergoing laparoscopic colorectal surgery. Methods: This study was a randomized controlled trial. One hundred and twenty patients who underwent laparoscopic colorectal surgery at Cancer Hospital of Chinese Academy of Medical Sciences from December 1, 2022 to May 31, 2023 were selected and randomly divided into two groups by random number table method. Moderate neuromuscular blockade [train of four stimulations count (TOFC)=1-2] was maintained in patients of the control group (group C, n=60) and pneumoperitoneum pressure level was set at 15 mmHg(1 mmHg=0.133 kPa). DNMB [post-tonic stimulation count (PTC)=1-2] was maintained in patients of the DNMB combined with low pneumoperitoneum pressuregroup (group D, n=60) and pneumoperitoneum pressure level was set at 10 mmHg. The primary measurement was incidence of moderate to severe pain at 1 h after surgery. The secondary measurements the included incidence of moderate to severe pain at 1, 2, 3, 5 d and 3 months after surgery, the incidence of rescue analgesic drug use, the doses of sufentanil in analgesic pumps, surgical rating scale (SRS) score, the incidence of postoperative residual neuromuscular block, postoperative recovery [evaluated with length of post anesthesia care unit (PACU) stay, time of first exhaust and defecation after surgery and length of hospital stay] and postoperative inflammation conditions [evaluated with serum concentration of interleukin (IL)-1ß and IL-6 at 1 d and 3 d after surgery]. Results: The incidence of moderate to severe pain in group D 1 h after surgery was 13.3% (8/60), lower than 30.0% (18/60) of group C (P<0.05). The incidence of rescue analgesia in group D at 1 h and 1 d after surgery were 13.3% (8/60) and 4.2% (5/120), respectively, lower than 30.0% (18/60) and 12.5% (15/120) of group C (both P<0.05). The IL-1ß level in group D was (4.1±1.8)ng/L at 1 d after surgery, which was lower than (4.9±2.6) ng/L of group C (P=0.048). The IL-6 level in group D was (2.0±0.7)ng/L at 3 d after surgery, which was lower than (2.4±1.1) ng/L of group C (P=0.018). There was no significant difference in the doses of sufentanil in analgesic pumps, intraoperative SRS score, incidence of neuromuscular block residue, time spent in PACU, time of first exhaust and defecation after surgery, incidence of nausea and vomiting, and length of hospitalization between the two groups (all P>0.05). Conclusion: DNMB combined with low pneumoperitoneum pressure anesthesia strategy alleviates the early-stage pain in patients after laparoscopic colorectal surgery.

Impact of shear stress on sacral pressure injury from table rotation during laparoscopic colorectal surgery performed in the lithotomy position.

This study aimed to evaluate the impact of shear stress on surgery-related sacral pressure injury (PI) after laparoscopic colorectal surgery performed in the lithotomy position. We included 37 patients who underwent this procedure between November 2021 and October 2022. The primary outcome was average horizontal shear stress caused by the rotation of the operating table during the operation, and the secondary outcome was interface pressure over time. Sensors were used to measure shear stress and interface pressure in the sacral region. Patients were divided into two groups according to the presence or absence of PI. PI had an incidence of 32.4%, and the primary outcome, average horizontal shear stress, was significantly higher in the PI group than in the no-PI group. The interface pressure increased over time in both groups. At 120 min, the interface pressure was two times higher in the PI group than in the no-PI group (PI group, 221.5 mmHg; no-PI group, 86.0 mmHg; p < 0.01). This study suggested that shear stress resulting from rotation of the operating table in the sacral region by laparoscopic colorectal surgery performed in the lithotomy position is the cause of PI. These results should contribute to the prevention of PI.

Outcomes in robotic-assisted compared to laparoscopic-assisted colorectal surgery in a newly established colorectal tertiary center: a retrospective comparative cohort study.

The robotic platform matches or surpasses laparoscopic surgery in postoperative results. However, limited date and slow adoption are noticed in the middle east. We aimed to report outcomes of robotic and laparoscopic colorectal surgery performed by fellowship-trained robotic colorectal surgeons and compare it to larger more experienced centers. Retrospective review of prospectively collected data between 2021 and 2023 of 107 patients who had robotic-assisted or laparoscopic-assisted colorectal surgery was included in the study. The outcomes were overall morbidity, serious morbidity, mortality, conversion to open, length of hospital stay, and the quality of oncological specimen. Of 107 patients, 57 were in the robotic and 50 were in the laparoscopic surgery groups. Overall, there were no significant differences in overall morbidity (46.8 vs. 53.2%, p = 0.9), serious morbidity (10.5 vs. 8%, p = 0.7), or mortality (0 vs. 4%, p = 0.2). Regarding oncological outcomes, there were no significant difference between the two groups regarding the number of lymph node harvested (17.7 ± 6.9 vs 19.0 ± 9.7, p = 0.5), R0 resections (92.7 vs. 87.1%, p = 0.5), and the rate of complete mesorectal excision (92.7 vs. 71.4%, p = 0.19). The study found that the robotic group had an 86% reduction in conversion rate to open surgery compared to the laparoscopic group, despite including more obese and physically dependent patients (OR = 0.14, 95% CI 0.03-0.7, p = 0.01). Robotic surgery appears to be a safe and effective as laparoscopic surgery in smaller colorectal surgery programs led by fellowship-trained robotic surgeons, with outcomes comparable to those of larger programs.

Effect of probiotics and synbiotics on complications of wound infection after colorectal surgery: A meta-analysis.

Wound infection is a serious complication that impacts the prognosis of patients after colorectal surgery (CS). Probiotics and synbiotics (Pro and Syn) are live bacteria that produce bacteriostatic agents in the intestinal system and have a positive effect on postoperative wound infections. The purpose of this study was to evaluate the effect of Pro and Syn on complications of wound infection after CS. In November 2023, we searched relevant clinical trial reports from Pubmed, Cochrane Library, and Embase databases and screened the retrieved reports, extracted data, and finally analysed the data by using RevMan 5.3. A total of 12 studies with 1567 patients were included in the study. Pro and Syn significantly reduced total infection (OR, 0.44; 95% CI, 0.35, 0.56; p < 0.00001), surgical incision site infection (SSI) (OR, 0.61; 95% CI, 0.45, 0.81; p = 0.002), pneumonia (OR, 0.43; 95% CI, 0.25, 0.72; p = 0.001), urinary tract infection (OR, 0.28; 95% CI, 0.14, 0.56; p = 0.0003), and Pro and Syn did not reduce anastomotic leakage after colorectal surgery (OR, 0.84; 95% CI, 0.50, 1.41; p = 0.51). Pro and Syn can reduce postoperative wound infections in patients with colorectal cancer, which benefits patients' postoperative recovery.

Impact of hospital volume on failure to rescue for complications requiring reoperation after elective colorectal surgery: multicentre propensity score-matched cohort study.

BACKGROUND: It has previously been reported that there are similar reoperation rates after elective colorectal surgery but higher failure-to-rescue (FTR) rates in low-volume hospitals (LVHs) versus high-volume hospitals (HVHs). This study assessed the effect of hospital volume on reoperation rate and FTR after reoperation following elective colorectal surgery in a matched cohort. METHODS: Population-based retrospective multicentre cohort study of adult patients undergoing reoperation for a complication after an elective, non-centralized colorectal operation between 2006 and 2017 in 11 hospitals. Hospitals were divided into either HVHs (3 hospitals, median ≥126 resections per year) or LVHs (8 hospitals, <126 resections per year). Patients were propensity score-matched (PSM) for baseline characteristics as well as indication and type of elective surgery. Primary outcome was FTR. RESULTS: A total of 6428 and 3020 elective colorectal resections were carried out in HVHs and LVHs, of which 217 (3.4%) and 165 (5.5%) underwent reoperation (P < 0.001), respectively. After PSM, 142 patients undergoing reoperation remained in both HVH and LVH groups for final analyses. FTR rate was 7.7% in HVHs and 10.6% in LVHs (P = 0.410). The median Comprehensive Complication Index was 21.8 in HVHs and 29.6 in LVHs (P = 0.045). There was no difference in median ICU-free days, length of stay, the risk for permanent ostomy or overall survival between the groups. CONCLUSION: The reoperation rate and postoperative complication burden was higher in LVHs with no significant difference in FTR compared with HVHs.

Same day discharge in colorectal surgery: Who requires unplanned overnight monitoring?

BACKGROUND: Enhanced Recovery After Surgery protocols and minimally invasive surgery have decreased colorectal length of stay. Our institution implemented a Same Day Discharge (SDD) colorectal protocol, and this study evaluates factors associated with unplanned admission. METHODS: . Retrospective review was performed from February 2019 to January 2022. Admitted SDD candidates were identified, and their course evaluated. Demographics, clinical characteristics, and outcomes were compared between cohorts. RESULTS: Review identified 152 potential SDD patients, 47 successfully discharged. Of the 105 admitted patients, the most common reasons were operative complexity (47.6 â€‹%) and social reasons (23.8 â€‹%). No differences were seen in operative times, gender, BMI, anticoagulation, or diabetes. The admission cohort was more likely to undergo low anterior resection or right colectomy and was older in age. Case complexity was the highest factor for affecting discharge. CONCLUSION: SDD can be feasible after colectomy, but in certain patients may require deviation. The most common factors requiring admission were complexity and social factors.

Association of county-level food deserts and food swamps on postoperative outcomes among patients undergoing colorectal surgery.

BACKGROUND: Although malnutrition has been linked to worse healthcare outcomes, the broader context of food environments has not been examined relative to surgical outcomes. We sought to define the impact of food environment on postoperative outcomes of patients undergoing resection for colorectal cancer (CRC). METHODS: Patients who underwent surgery for CRC between 2014 and 2020 were identified from the Medicare database. Patient-level data were linked to the United States Department of Agriculture data on food environment. Multivariable regression was used to examine the association between food environment and the likelihood of achieving a textbook outcome (TO). TO was defined as the absence of an extended length of stay (≥75th percentile), postoperative complications, readmission, and mortality within 90 days. RESULTS: A total of 260,813 patients from 3017 counties were included in the study. Patients from unhealthy food environments were more likely to be Black, have a higher Charlson Comorbidity Index, and reside in areas with higher social vulnerability (all P < .01). Patients residing in unhealthy food environments were less likely to achieve a TO than that of patients residing in the healthiest food environments (food swamp: 48.8% vs 52.4%; food desert: 47.9% vs 53.7%; P < .05). On multivariable analysis, individuals residing in the unhealthy food environments had lower odds of achieving a TO than those of patients living in the healthiest food environments (food swamp: OR, 0.86; 95% CI, 0.83-0.90; food desert: OR, 0.79; 95% CI, 0.76-0.82); P < .05). CONCLUSION: The surrounding food environment of patients may serve as a modifiable sociodemographic risk factor that contributes to disparities in postoperative CRC outcomes.

Non-malignant left colon emergency surgery: evaluation of factors affecting clinical outcomes and complications.

BACKGROUND: Emergency colorectal resections hold a significant position in general surgical practice, and pathologies of the left colon are relatively common. This study was conducted to assess the outcomes of isolated left colon surgeries with benign etiologies, drawing on clinicopathological and biochemical data. METHODS: We carried out a retrospective review and statistical analysis of demographic, clinical, and laboratory data of patients who underwent left colon surgery at the general surgery clinic of a tertiary care hospital, excluding those with malignancy-related emergencies, from January 2017 to January 2022. RESULTS: The average age of the 48 patients in the study was 56.9±16.4 years. Complicated acute diverticulitis was the most frequent indication for emergency surgery (n=19, 39.6%). The Hartmann procedure was the surgical technique most often employed (n=30, 62.5%). The rates of postoperative morbidity and mortality within 30 days were 27.1% and 8.3%, respectively. Increased postoperative morbidity was linked to advanced age (mean 65.4±15.8 vs. 53.8±15.7, p=0.028), the preoperative administration of vasopressors, lower platelet counts, hypoalbuminemia (<3 mg/dl), and azotemia (blood urea nitrogen >20 mg/dl). There was no statistically significant correlation between comorbidities, American Society of Anesthesiologists (ASA) scores, surgical methods, or other clinical data and postoperative outcomes. CONCLUSION: For emergency colorectal surgery pertaining to left colon pathologies, it is critical to conduct a comprehensive evaluation in the perioperative period, especially for elderly and hypotensive patients with renal function abnormalities and for those requiring vasopressors.
