Can serum tumor necrosis factor-alpha predict peritoneal adhesions prior to secondary laparoscopic procedures?

AIM OF THE STUDY

This study aimed to investigate the incidence and degree of postoperative intra-abdominal adhesions(POAs) in secondary laparoscopic procedures and assess the power of the preoperative levels of tumor necrosis factor-alpha(TNF-α) and interleukin-1 beta(IL-1β) and selected peripheral inflammatory biomarkers(PIBs) in the prediction of the development and extent of POA.

PATIENTS AND METHODS

This prospective study enrolled 103 patients who had previously undergone at least one or more laparoscopic abdominal or gynecological operations. We examined TNF-α, IL-1β, and PIBs, namely C-reactive protein, white blood cell count, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio, and systemic immune-inflammation index(SII) according to the presence, location, and score of adhesions determined during secondary laparoscopic procedures.

RESULTS

Only age, postoperative adhesion index(PAI) score, NLR, SII, TNF-α, and IL-1β resulted in a significant difference in the existence of adhesion(P<0.05). The correlation analysis of TNF-α with variables showed that the PAI score and IL 1β levels had a significantly positive correlation.

CONCLUSION

The presence and extent of POA could be predicted by examining the preoperative TNF-α level in patients who had laparoscopic abdominal surgery previously. We could overcome adverse events during secondary laparoscopic procedures by assessing high-risk patients and integrating a personalized surgical approach to managing selected patients.

The effect of patient transfer type to the operating room on surgical site infection: Concerns versus evidence

BACKGROUND

Concerns about surgical site infection (SSI) give rise to practices and procedures not evidence-based.

OBJECTIVES

This study investigates whether the type of patient transfer to operating rooms plays a role in developing surgical site infection.

METHODS

Three thousand four hundred and seventy-one patients were divided into two groups: transfer group with stretcher (ST) (n = 1699) and patient bed transfer group (PBT) (n = 1772). The data of the two groups and the SSI rates were comparatively analyzed.

RESULTS

The SSI rate was 2.5% (n = 43) in the ST group and 2.8% (n = 49) in the PBT group, and there was no statistically significant difference. Both types of patient transfer had similar effects on the probability of SSI development. The odds ratio was 1.095 for stretcher transfer while 0.913 for patient bed transfer.

CONCLUSION

Patients transfer to operating rooms on their beds are comfortable and safe. Furthermore, it has a similar effect to stretcher transfer on the probability of surgical site infection. Therefore, it is safer and cheaper to act based on evidence instead of trusting our concerns.

Zig Maneuver in Total Extraperitoneal Inguinal Hernia Repair

BACKGROUND

The difficulties in the hernia sac dissection in repairing large inguinal hernias with the endoscopic total extraperitoneal (TEP) technique prolong the operation and increase the risk of injury. This study investigates the effectiveness of the Zig maneuver (ligation of the hernia sac at the deep inguinal ring) in TEP in male patients with L3 inguinal hernia by European Hernia Society classification.

MATERIALS AND METHODS

A total of 224 male patients with L3 inguinal hernia who underwent laparoscopic TEP surgery in 2018 and 2019 were retrospectively screened and included in the study. The patients were divided into 2 groups as Zig group (n=99) and the non-Zig group (n=125), depending on whether the Zig maneuver was performed during TEP application.

RESULTS

The mean patient age was 45.49 for the non-Zig group and 47.12 for the Zig group. The median operative time was 50 minutes in the non-Zig group and 43 minutes in the Zig group (P<0.005). The median value of the postoperative first 24 hours pain score was 3 in the non-Zig group and 2 in the Zig group (P=0.033). Scrotal edema was 7.2% in the non-Zig group and 1% in the Zig group (P=0.023). According to logistic regression analysis, the Zig maneuver reduced the probability of scrotal edema by 87% in almost the entire population (odds ratio=0.130, 95% confidence interval: 0.016-1.047). There was no statistically significant difference between the groups in terms of early and late recurrence.

CONCLUSIONS

Zig maneuver shortened the operative time and significantly reduced the feeling of pain in the first 24 hours postoperatively in male patients with indirect L3 hernia who underwent endoscopic TEP. It also significantly reduced the likelihood of scrotal edema in almost the entire population. As a result, the Zig maneuver is an effective method that could be applied during endoscopic TEP.

Diagnostic Value of Preoperative Haemoglobin, Albumin, Lymphocyte and Platelet (HALP) Score in Predicting Tumour Budding in Colorectal Cancer

OBJECTIVE

To investigate the value of preoperative haemoglobin, albumin, lymphocyte, and platelet (HALP) score in predicting tumour budding in colorectal carcinoma.

STUDY DESIGN

Observational study.

PLACE AND DURATION OF STUDY

University of Health Sciences, Başakşehir Çam and Sakura City Hospital İstanbul/Turkey, between May 2020 and May 2021.

METHODOLOGY

The colorectal cancer patients who underwent surgery were divided into two groups according to the presence or absence of tumour budding. A total of 110 patients were included in the study, and there were 31 patients in group 1 and 79 patients in group 2. The predictive value of the HALP score in predicting tumour budding at the determined cut-off point was evaluated.

RESULTS

The mean HALP score was similar in both groups (p=0.459). The rate of lymphovascular invasion was higher in group 2 (p=0.002), and T3 and T4 tumours were more common in group 2 (p<0.001). The number of metastatic lymph nodes was higher in group 2 (p=0.049). When the patients in group 2 were divided into subgroups according to the degree of tumour budding, the HALP score differed between intermediate and high budding groups (p=0.032). A HALP value of >31.6 predicted the presence of tumour budding with a sensitivity of 70.89% and a specificity of 48.39%.

CONCLUSION

The presence of tumour budding is associated with aggressive phenotypic features in colorectal carcinoma. The preoperative prediction of tumour budding can serve as a guide in the development of individualised therapy plans. The HALP score was associated with the presence of intermediate or high degree of tumour budding.

Extended View Totally Extraperitoneal Technique and Its Advantages in Laparoscopic Inguinal Hernia Repair

Objective: Endoscopic total extraperitoneal (TEP) is used increasingly in inguinal hernias. Perhaps the most fundamental difficulty of the classical TEP method is that the dissection plan it offers is overly limited, which is among the reasons why techniques other than TEP are preferred in large scrotal hernias. This study discusses our experience with the extended view totally extraperitoneal (e-TEP) method, which significantly expands the dissection plan compared to the classical method. Methods: Patients who had inguinal hernia surgery in 2018 and 2019 were retrospectively analyzed, and 21 male patients with L3 inguinal hernia by European Hernia Society classification, who underwent laparoscopic e-TEP surgery, were included in the study. Patient data were obtained from the hospital's electronic database and patient files. One year after the surgery, the patients were invited to the hospital by telephone and re-examined. Results: The median patient age was 47 years. The mean duration of surgery was 43.6 minutes, and the median postoperatively pain score in the first 24 hours was 1.975. Zig maneuver was performed in 85.7%, and drains were placed in 33.4% of patients. In 28.6% of patients, the peritoneal violation occurred. However, there was no conversion to another surgical technique. The mean length of stay was 1.33 days. Two patients had seroma, one had scrotal edema, and one had urinary retention. No recurrence was observed in any patient during the 1-year follow-up. Conclusions: According to our experience, the e-TEP technique can be safely performed in scrotal hernias as it offers a larger dissection plane. It also allows patients with large scrotal hernias to benefit from all the advantages of the TEP technique.

Which Is More Effective: Laparoscopic or Open Partial Cholecystectomy?

Objective: In laparoscopic cholecystectomy, partial cholecystectomy is usually preferred when the anatomic exploration is not enough to prevent bile duct injury and other complications. Some surgeons choose laparoscopically to perform partial cholecystectomy, whereas others convert to open surgery. In this study, we aim to discuss and compare the effectiveness of laparoscopic partial cholecystectomy (LPC) and open partial cholecystectomy (OPC). Materials and Methods: The data of 4712 patients who underwent laparoscopic cholecystectomy between 2012 and 2020 were reviewed. A total of 98 patients who had partial cholecystectomy were included in the study. Patients were examined in two groups according to whether the procedure was open or laparoscopic. The first group of patients was named the OPC group (n = 52), and the second group of patients was the LPC group (n = 46). The data of the two groups were comparatively analyzed. Results: The mean operative time and the postoperative hospital stay, respectively, were 118.2 minutes and 4.8 days in the OPC group, and 87.3 minutes and 2.55 days in the LPC group (P < .005 and P = .005). It was found that wound infection decreased by 83.1% (P = .026; odds ratio [OR] = 0.169) in the LPC group compared with the OPC group, and the probability of developing incisional hernia decreased by 81.1% (P = .014; OR = 0.189). At least one complication was observed in 17 patients in the OPC group and in 7 patients in the LPC group (P = .045). The probability of developing complications in any patient was 63% lower in the LPC group (P = .049; OR = 0.370). Conclusions: The indications that cause the surgeon to perform partial cholecystectomy are inherently open to complications, regardless of the surgical technique used. However, the laparoscopic operation has advantages such as shorter operation time, shorter postoperative hospital stay, lower risk of wound infection and incisional hernia rate, and lower complication rate than the open procedure. However, if the team performing the surgery does not have enough experience, they should never hesitate to switch to open cholecystectomy.

Adrenomedulline improves ischemic left colonic anastomotic healing in an experimental rodent model

BACKGROUND

Leakage from colonic anastomosis is a major complication causing increased mortality and morbidity. Ischemia is a well-known cause of this event. This study was designed to investigate the effects of adrenomedullin on the healing of ischemic colon anastomosis in a rat model.

METHODS

Standardized left colon resection 3 cm above the peritoneal reflection and colonic anastomosis were performed in 40 Wistar rats that were divided into four groups. To mimic ischemia, the mesocolon was ligated 2 cm from either side of the anastomosis in all of the groups. The control groups (1 and 2) received no further treatment. The experimental groups (3 and 4) received adrenomedullin treatment. Adrenomedullin therapy was started in the perioperative period in group 3 and 4 rats (the therapeutic groups). Group 1 and group 3 rats were sacrificed on postoperative day 3. Group 2 and group 4 rats were sacrificed on postoperative day 7. After careful relaparotomy, bursting pressure, hydroxyproline, malondialdehyde, interleukin 6, nitric oxide, vascular endothelial growth factor, and tumor necrosis factor alpha levels were measured. Histopathological characteristics of the anastomosis were analyzed.

RESULTS

The group 3 animals had a significantly higher bursting pressure than group 1 (p<0.05). Hydroxyproline levels in group 1 were significantly lower than in group 3 (p<0.05). The mean bursting pressure was significantly different between group 2 and group 4 (p<0.05). Hydroxyproline levels in groups 3 and 4 were significantly increased by adrenomedullin therapy relative to the control groups (p<0.05). When all groups were compared, malondialdehyde and nitric oxide were significantly lower in the control groups (p<0.05). When vascular endothelial growth factor levels were compared, no statistically significant difference between groups was observed. Interleukin 6 and tumor necrosis factor alpha were significantly decreased by adrenomedullin therapy (p<0.05). The healing parameters and inflammatory changes (e.g., granulocytic cell infiltration, necrosis, and exudate) were significantly different among all groups (p<0.05).

CONCLUSION

Adrenomedullin had positive effects on histopathologic anastomotic healing in this experimental model of ischemic colon anastomosis.

Evaluation of periodontal parameters in patients undergoing peritoneal dialysis or hemodialysis

OBJECTIVE

To analyze and compare periodontal parameters in chronic renal failure (CRF) patients undergoing peritoneal dialysis (PD) therapy with a group of patients on hemodialysis (HD) treatment and healthy controls (C).

PARTICIPANTS

Seventy-five PD patients (mean age: 44 +/- 12 years) were matched with 41 HD patients (mean age: 46 +/- 15 years) and 61 C (mean age: 46 +/- 18 years).

METHODS

Plaque (PI) and calculus (CSI) accumulation and gingival bleeding (GI) were recorded with the appropriate indices. Periodontal condition was assessed using the probing pocket depth (PPD). One-way anova test, Pearson chi-squared test, Mann-Whitney U-test and Kruskal-Wallis test were performed to compare PD patients with HD patients and healthy C.

RESULTS

Plaque Index values were significantly higher (P < 0.001) in the PD and HD groups than the C group. GI values were significantly higher (P < 0.01) in the HD group than the PD group. Finally, CSI values in the PD and HD groups were also significantly higher (P < 0.001) than the C group.

CONCLUSIONS

Chronic renal failure patients on PD treatment are more susceptible to periodontal diseases like HD patients. Thus, it is very important to maintain an optimal oral hygiene level. Further studies on periodontal parameters of only PD patients are needed to get more information on the oral health status of this patient group.

Cecal diverticulitis mimicking acute Appendicitis: a report of 4 cases

Diverticulum of the cecum is a rare, benign, generally asymptomatic lesion that manifests itself only following inflammatory or hemorrhagic complications. Most patients with inflammation of a solitary diverticulum of the cecum present with abdominal pain that is indistinguishable from acute appendicitis. The optimal management of this condition is still controversial, ranging from conservative antibiotic treatment to aggressive resection. We describe four cases that presented with symptoms suggestive of appendicitis, but were found at operation to have an inflamed solitary diverticulum.

Dental and periodontal findings in hemodialysis patients

OBJECTIVE

Oral health problems of chronic renal failure patients can compromise systemic health. This study compared the periodontal and dental health status of patients on hemodialysis (HD) with healthy controls (C).

STUDY DESIGN

Seventy-six HD patients and 61 controls were examined for plaque deposits, gingivitis, periodontitis, calculus accumulation and oral health status.

RESULTS

There was no statistically significant difference in the measurement of probing pocket depths (PPD) in HD and C groups, but a highly significant difference was found for plaque index (P < 0.001), gingival index (GI) (P = 0.007) and calculus surface index (P < 0.001). There was a highly significant difference for GI (P = 0.001) and PPD scores (P < 0.001) between subgroups receiving HD for <3 years or more. A positive correlation between time on dialysis and parameter of missing teeth (r = 0.259; P = 0.024), GI scores (r = 0.474; P < 0.001) and measurement of PPD (r = 0.481; P < 0.001) was found in the HD group. Decayed, missing and filled teeth index scores were higher in the controls than the HD group, with no statistical significance.

CONCLUSIONS

The dental and periodontal health status of HD patients is comparable with healthy controls, but becomes worse with time on dialysis. Thus, oral health maintenance is of utmost importance in this patient group.
