RESUMEN
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.
RESUMEN
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.
RESUMEN
BACKGROUND: There are few comparative studies of the clinical outcomes after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). The aim of the study was to compare diabetes- and metabolic disorder-related outcomes following RYGB and SG, based on data for matched participants. METHODS: This was a retrospective matched study using data from 2011-2018. Patients with type-2 diabetes undergoing RYGB (n=35) were matched with up to 2 RYGB participants (n=56) regarding age, sex, body mass index, hemoglobin A1c level, medication use, diabetes duration, and blood pressure. RESULTS: All surgeries were performed laparoscopically without complications or malnutrition during 24 months of follow-up. Both surgical procedures achieved excellent diabetes remission and weight loss. RYGB was associated with a significantly higher diabetes medication discontinuation rate 24 months postoperatively (RYGB: 87.5% vs. SG: 68.6%; P<0.05), better reduction in serum cholesterol and low-density lipoprotein-c levels, as well as better diabetes control compared with SG. The incidence of microvascular and macrovascular complications showed no significant difference between two groups. CONCLUSIONS: In this matched retrospective study, although RYGB and SG were both excellent surgeries for treating obesity in patients with type-2 diabetes, RYGB was associated with better results compared with SG regarding dyslipidemia remission and metabolic disorder-related medication reduction.
RESUMEN
BACKGROUND: NLR family CARD domain containing 5 (NLRC5) is involved the initiation and progression of several cancers. However, its role in hepatocellular carcinoma (HCC) is still unclear. This study aimed to explore the expression, clinical significance, and regulated gene sets of NLRC5 in HCC. METHODS: Data related to NLRC5 was extracted from The Cancer Genome Atlas (TCGA) database and analyzed. Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to verify the NLRC5 mRNA expression in HCC. Immunohistochemistry (IHC) and western blot were performed to detect the NLRC5 protein level in HCC. The clinical significance of NLRC5 was investigated after separating patients into NLRC5-positive and NLRC5-negative groups based on the IHC results. Gene set enrichment analysis (GSEA) was performed to detect gene sets regulated by NLRC5 in HCC. RESULTS: Increased NLRC5 mRNA and protein expression were found in HCC tissues compared to paracancerous tissues. Moreover, enhanced NLRC5 protein expression was associated with a higher presence rate of cirrhosis, a higher TNM stage, and a shorter 3-year overall survival (OS) of HCC participants. Finally, gene sets related to cancer metastasis were up-regulated in the NLRC5 high phenotype. CONCLUSIONS: NLRC5 is a potential marker for the diagnosis and prognostic assessment of HCC.
RESUMEN
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 pre-operatic 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.
RESUMEN
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 postpre-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 CONCLUSIONS: PLR and NLR measurements can provide important diagnostic and prognostic results in patients with resectable gastric cancer.

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 first-line 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.
RESUMEN
OBJECTIVE: To evaluate the efficacy of laparoscopic Roux-en-Y gastric bypass (LRYGB) in the treatment of type 2 diabetes mellitus(T2DM). METHODS: Clinical data of 62 cases undergoing LRYGB from May 2010 to October 2011 were analyzed retrospectively. RESULTS: LRYGB was completed in 58 patients successfully. The mean operative time was(144.5±59.0) min and the mean intraoperative blood loss was(57.8±135.5) ml. Postoperatively two patients developed anastomotic bleeding, one gastric paralysis, one anastomotic leak, and one malnutrition, which were all healed by conservation treatment. One patient developed anastomotic stricture which was alleviated by balloon dilatation. Forty-nine cases were followed up for six months, in whom 34 patients required no further medical treatment, 9 received less medicines, and 6 were inactive. Body mass index, fasting C-peptide, and HbA1c were improved postoperatively. Compared to other patients, the 34 patients with clinical complete remission had higher BMI and shorter disease course(both P<0.05). CONCLUSIONS: LRYGB can safely and efficiently be applied in T2DM patients. Short-term efficacy is satisfactory and the long-term outcomes require further evaluation.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) has become the gold standard operation for morbid obesity, because effects of LRYGB are quick and lasting. However, there are many potential risks due to the operative complexity and long learning curve. There are early and late complications after LRYGB. If the complications are not diagnosed and treated in time and correctly, serious results even death, may occur. Mortality after LRYGB is 0.87%. It is important for the continous and healthy development of LRYGB that postoperative complications can be diagnosed and managed in time and effectively.
