COMPLICATIONS OF INTRA ABDOMINAL DRAINS: A SINGLE CENTER EXPERIENCE

Objective: To compare frequency of intra-abdominal complications in drainage and non-drainage group among patents who underwent intra-abdominal surgeries. Study Design: Comparative prospective study. Place and Duration of Study: Department of Surgery, Pakistan Ordinance Factory, Wah Cantt, from Mar 2018 to Jul 2018. Methodology: There were 32 patients, 16 in each group. Patients were selected through the process of consecutive sampling. Patients were randomly divided into two groups (random number table method); group A patients underwent intra-abdominal drain while group B was non-drainage group. Patients were followed up for 7 days and observed for complications. Results: Total 32 patients were included in the study. There were 14 (43.8%) males and 18 (56.3%) females. Mean age of patients was 43.2 ± 9.5 years. Drain group showed significantly low anastomosis leakage (p=0.02), wound infection (p=0.05), mortality (p=0.04), pulmonary complications (p=0.05) and bleeding (p=0.03) as compared to the non-drain group. Conclusion: Intra-abdominal drains are associated with several complications. Anastomosis leakage is the most common complication following pulmonary complications and bleeding. However, drains help in early detection of complications and timely management of such complications leads to better outcome of a surgical procedure.

Colonic invagination anastomosis in surgery of complicated forms of diverticular disease

AIM: to evaluate the prospects of using a colorectal invaginated anastomosis in patients with complicated diverticular disease (CDD).PATIENTS AND METHODS: during the period from 2014 to 2020, colorectal invaginated anastomosis, was used in 42 patients: 18 patients with CDD and 20 patients with colorectal cancer for stoma closure after Hartmann’s procedure. The comparison group consisted of 24 patients with CDD and 20 patients with colorectal cancer for stoma closure after Hartmann’s procedure: colorectal anastomosis was created here using traditional double-row handsewn technique. All patients underwent surgery with open access, while the primary anastomosis was performed in 20 (47.6%) patients, and in 22 (52.4%) patients of the group underwent stoma takedown.RESULTS: no anastomosis leakage developed in the main group. Moreover, the presence of single small diverticula with a diameter of 2–3 mm near the area of the anastomosis was not an indication to extend the resection borders. In the control group, in 13 (54.2%) patients, small diverticula were detected in the anastomosis are as well and required to expand the proximal border of resection. In this group, anastomosis leakage occurred in 2 (6.8%) patients with diverticular disease and required Hartmann’s procedure.CONCLUSION: the colorectal invaginated anastomosis is justified for patients with CDD during stoma takedown because it minimizes the risk of anastomosis leakage.

Case Report: A Squamous Cell Lung Carcinoma Patient Who Responded to Neoadjuvant Immunochemotherapy but Died From Anastomosis Leakage or/and irAEs: Immune Microenvironment and Genomic Features Changes

Clinical trials indicated that PD-1/PD-L1 inhibitors significantly improve the survival rate of patients with advanced non-small cell lung cancer (NSCLC) and induce immune-related adverse events (irAEs). Thus, the molecular and immune characteristics during PD-1/PD-L1 inhibitor therapy are worth investigating further. We report the case of a 62-year-old male patient diagnosed with stage IIIA squamous cell lung carcinoma (SQCC) who responded to neoadjuvant and adjuvant nivolumab combined chemotherapy but died from anastomosis leakage or/and irAEs. In the pretreatment tumor biopsy, PD-L1 expression was negative and a few T cells, NK cells, and macrophages had infiltrated the tumor. Wild-type EGFR/STK11, mutant TP53, microsatellite stability, and low tumor mutational burden were also found at baseline. After neoadjuvant immunochemotherapy, the tumor was significantly reduced, PD-L1 expression levels were increased by 50%, and more CD8+ and CD8+ PD-1+ T cells had infiltrated the resected tumor tissue. Immune-related lung injury occurred during adjuvant immunochemotherapy, and serum levels of C-reactive protein, IL-13, IL-4, eotaxin, VEGF-A, IL-8, and IFN-gamma were increased. This case demonstrates a squamous cell lung carcinoma patient who responded to neoadjuvant immunochemotherapy that reshaped the tumor immune environment from “cold” to “hot.” Unfortunately, the patient eventually died from anastomosis leakage or/and irAEs during adjuvant immunochemotherapy.

Leakage of colorectal anastomosis: the role and possibilities of visualisation (review)

In the literature review, the problem of colorectal anastomosis leakage is considered with an emphasis on the role and capabilities of radiology, including methodological features, diagnostic effectiveness and characteristic manifestations at various times after surgery, also controversial and unresolved issues of the use of various methods of radiation research are noted.

Improvement of surgical complications using single-lumen endotracheal tube intubation and artificial carbon dioxide pneumothorax in esophagectomy: a meta-analysis

Background Esophageal cancer has a poor prognosis. Surgery is the main treatment but involves a high risk of complications. Some surgical strategies have tried to eliminate complications. Our meta-analysis tried to find the benefits of single-lumen endotracheal tube intubation with carbon dioxide (CO2) inflation. Methods A systematic search of studies on esophagectomy and CO2 inflation was conducted using PubMed, Medline, and Scopus. The odds ratio of post-operative pulmonary complications and anastomosis leakage were the primary outcomes. The standardized mean difference (SMD) in post-operative hospitalization duration was the secondary outcome. Results The meta-analysis included four case-control studies with a total of 1503 patients. The analysis showed a lower odds ratio of pulmonary complications in the single-lumen endotracheal tube intubation in the CO2 inflation group (odds ratio: 0.756 [95% confidence interval, CI: 0.518 to 1.103]) compared to that in the double-lumen endotracheal tube intubation group, but anastomosis leakage did not improve (odds ratio: 1.056 [95% CI: 0.769 to 1.45])). The SMD in hospitalization duration did not show significant improvement. (SMD: -0.141[95% CI: − 0.248 to − 0.034]). Conclusions Single-lumen endotracheal tube intubation with CO2 inflation improved pulmonary complications and shortened the hospitalization duration. However, no benefit in anastomosis leakage was observed.

A Short-Term Outcome on Ligating the Different Levels of the Inferior Mesenteric Artery (IMA). A Prospective Cohort Study.

Background: This study is to analyze the impact on the level of Inferior mesenteric artery (IMA) ligation of Colorectal cancer surgery. The retrieval of lymph nodes (LNs) and anastomotic leakage was the main concern of this study. Methods: In this prospective study, the high and low ligation cases were selected. The retrieved LNs from roots of the inferior mesenteric artery (IMA) and left colic artery (LCA) was sent for histopathological examination (HPE), irrespective of the method of ligation. The observation of HPE results and Anastomosis leakage were analyzed.Result: In the total numbers of 369 cases, 12 cases were cancer positive LNs at the root of IMA despite 349 harvested LNs. On another hand, just one case showed LCA positive LNs obliviously because just 12 cases were had harvested LNs at the root of LCA. where Two cases of leakage were seen in both groups over a three-month follow-up. Conclusions: This result signifies the importance of IMA root LNs clearance and concern of high ligation. However, the small number of cases demand further well-designed RCTs to make an evidence-based decision.

The effect of peroperative erythrocyte transfusion on infectious complications in patients with gastric cancer undergoing curative gastrectomy

Background: In this study, the effect of perioperative blood transfusion on infectious complications in patients undergoing curative surgery for gastric adenocarcinoma was investigated.Methods: The clinicopathological results of 312 patients who underwent curative gastrectomy were retrospectively analyzed. The effect of blood transfusion on the development of postoperative infectious complications were statistically analyzed.Results: In the subgroup of patients with intraoperative transfusion, surgical site infection incidence was found to be significantly higher in patient with 2U above ES transfusions. (p=0.014). In the subgroup of patients with postoperative transfusion, hospital stay (p<0.001), postoperative CRP values (p<0.001), surgical site infection incidence (p=0.049) and anastomosis leakage incidence (p<0.001) were found to be significantly higher in patient with 2U above ES transfusions. In the subgroup of patients with both intraoperative and postoperative transfusion, SSI, anastomotic leakage and any infective complication incidences were found to be significantly higher in patients with 2U and above transfusions. In multivariate analysis, age (p=0.015), BMI (p=0.011), intraoperative transfusion (p=0.011) and both intraoperative and postoperative transfusion (p=0.045) were found to be independent risk factors for infective complications.Conclusions: It was found that performing peroperative ES transfusion is associated with increased rates of infectious complications in patients undergoing curative gastrectomy for gastric cancer by causing immunomodulation.
