Introduction: For an indirect inguinal hernia (IIH), it is a challenge to repair the internal inguinal ring (IIR) with self-tissue reconstruction in laparoscopic repair. Aim: To evaluate the efficacy and safety of covering the IIR with the lateral umbilical fold (LUF) combined with patch repair in laparoscopic indirect inguinal hernia repair. Material and methods: Patients with IIH treated by trans-abdominal preperitoneal (TAPP) hernia repair at the Department of General Surgery, Shanghai Public Health Clinical Centre between September 2019 and March 2021 were retrospectively analyzed. In group I (n = 57) the LUF was overturned and sutured to cover the IIR under a laparoscope and subsequently repaired with a patch. In group II (n = 62), the IIR was not covered by the LUF but only repaired with a self-gripping mesh. Results: We noted a longer suture time in group I than in group II. Although the LUF was covered after suturing, no significant difference in postoperative pain was observed between the two groups. However, significant differences in surgery time and hospitalization cost (p < 0.05) were found. One case of recurrence was observed in group II. Conclusions: The LUF can be used in IIH to cover the IIR and is a feasible approach. The LUF covering the IIR has no significant difference in pain. [ABSTRACT FROM AUTHOR]

Introduction: The dissection of the preperitoneal space is performed using a monopolar instrument to prevent bleeding in laparoscopic transabdominal preperitoneal hernia repair (TAPP). It may also cause energy injuries and nerve damage. Aim: To assess the effectiveness and safety of dissection of the preperitoneal space without electrocoagulation (DPSWE) in TAPP throughout the process. Material and methods: A retrospective analysis of data of 134 patients was made. The electrocoagulation group (EG) relied on monopolar instruments. In the non-electrocoagulation group (NEG) mainly scissors were used without electrocoagulation. The patients were followed for up for 3 months. Intraoperative and postoperative conditions and other complications were observed. Results: The VAS scores in the NEG were lower than those in the EG (p < 0.05). The operation time in the NEG was shorter than that in the EG (p < 0.05). Hospitalization expenses, scrotal seroma formation, and rupture of hernia sac in the NEG were lower than those in the EG (p < 0.05). The intraoperative bleeding volume above 20 ml in the NEG was higher than that in the EG. There was no significant difference in the incidence of postoperative bleeding, vas deferens injury, intestinal injury, surgical site infection, length of hospital stay, urinary retention and hernia recurrence in the NEG and the EG (p > 0.05). There was no significant difference in the incidence of surgical site infections (SSIs) in the NEG and the EG. Conclusions: DPSWE is effective and safe. DPSWE may reduce postoperative pain and have no significant increase in postoperative bleeding. [ABSTRACT FROM AUTHOR]

Gastric cancer is the fourth most frequent cancer and the second cause of cancer-related mortalities worldwide. Platelets play an important and multifaceted role in cancer progression. Elevated mean platelet volume (MPV) detected in peripheral blood has been identified in various types of cancer. In the present study, we investigated the application value of MPV in early diagnostic and prognostic prediction in patients with resectable gastric cancer. In total, 168 patients with resectable gastric cancer were included and separated into the gastric cancer and healthy control groups according to median preoperatic MPV value (MPV low, <10.51 or MPV high, ≥10.51). The results showed that the pre-operatic MPV level was significantly higher in gastric cancer patients compared with the healthy subjects. Low pre-operatic MPV level correlated with improved clinicopathological features, including decreased depth of invasion, less lymphonodus metastasis and early tumor stage. The Kaplan-Meier plots showed that the patients with higher pre-operatic MPV had decreased overall survival (OS) and disease-free survival (DFS). Surgical tumor resection resulted in a significant decrease in the MPV level. The patients whose MPV level decreased following surgery had an improved OS. Multivariate Cox regression analysis revealed that the depth of invasion, lymphonodus metastasis, American Joint Committee on Cancer (AJCC) stage, and changes in MPV following surgery were prognostic factors affecting OS, and the AJCC stage and pre-operatic MPV were prognostic factors affecting DFS. In conclusion, MPV measurement can provide important diagnostic and prognostic results in patients with resectable gastric cancer. [ABSTRACT FROM AUTHOR]

The aim of the study was to investigate the application value of neutrophil to lymphocyte ratio (NLR) and the platelet to lymphocyte ratio (PLR) in the prediction of chemotherapy response and prognosis in patients with advanced gastric cancer. In total, 120 patients with unresectable gastric cancer were included and separated into two groups according to the median values of NLR or PLR (NLR low: <4.62 or NLR high: =4.62 and PLR low: <235 or PLR high: =235, respectively). Low baseline NLR level correlated with improved clinicopathological characteristics, including smaller tumor size, well differentiation and less metastasis. Low baseline PLR level also associated with less metastasis. Patients with a low baseline level of NLR or PLR had an improved response to chemotherapy. Patients with a higher baseline NLR and PLR had decreased progression-free survival (PFS) and overall survival (OS) ratios. Alterations in the NLR and PLR levels were associated with therapeutic efficacy and prognosis. The patients who remained in or switched to the low NLR level subgroup subsequent to firstline chemotherapy had an improved response and improved OS ratios, compared to the patients remaining in or switching to the high NLR level group. Similar results were observed when the PLR level was investigated. In conclusion, baseline NLR and PLR measurements, as well as changes of NLR and PLR following chemotherapy can predict the prognostic results in patients with unresectable gastric cancer.

BACKGROUND: Gastric cancer is the fourth most frequent cancer and the second cause of cancer-related deaths worldwide. China has a high incidence of gastric cancer. Inflammation is a critical component of tumor progression. It has been widely accepted that gastric cancer is an inflammation-driven cancer. In this study, we investigated the application value of systemic inflammatory response (SIR) markers, platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR), in early diagnosis and prognostic prediction in patients with resectable gastric cancer. MATERIALS AND METHODS: One hundred and sixty-two patients with resectable gastric cancer were included and separated into groups according to median pre-operative PLR or NLR values (PLR low: < 208 or PLR high: ≥ 208, and NLR low: < 4.02 or NLR high: ≥ 4.02, respectively). To evaluate the changes in PLR or NLR values after operation, we introduced the concept of post-/pre-operative PLR or NLR ratios (< 1 indicated PLR or NLR values were decreased after operation, while ≥ 1 suggested not decreased PLR or NLR values). RESULTS: Pre-operative PLR and NLR levels were significantly higher in gastric cancer patients compared with the healthy subjects. Low pre-operative PLR and NLR levels correlated with better clinicopathological features, including decreased depth of invasion, less lymph node metastasis and early tumor stage. Kaplan-Meier plots illustrated that higher pre-operative NLR and PLR had decreased overall survival (OS) and disease-free survival (DFS). Surgical tumor resection resulted in a significant decrease in both PLR and NLR levels. Patients whose post-/pre-operative PLR or NLR ratios < 1 had better OS.Multivariate Cox regression analysis revealed that tumor stage, pre-operative NLR level, and post/pre-operative NLR ratio are prognostic factors affecting DFS, while depth of invasion, lymph node metastasis, tumor stage, pre-operative PLR level, and post/pre-operative PLR ratio are prognostic factors affecting OS. CONCLUSIONS: PLR and NLR measurements can provide important diagnostic and prognostic results in patients with resectable gastric cancer. [ABSTRACT FROM AUTHOR]
