Background: The laparoscopic approach for colorectal cancers are still a matter of controversy. In the present study, we tried to compare the laparoscopy with open methods of colorectal resections.Methods: Retrospective study where patients diagnosed with colorectal cancer in our hospital from year 2014 January to December 2016 were taken. Total number of cases were 69 of which, the total number of right colon cases were 26. Out of twenty-six, 12 underwent open procedure and 14 underwent laparoscopic resections. Total number of left colon cancers were 09. Of these, 2 underwent open and 7 underwent laparoscopic procedure. Thirty-four (34) rectal cancers were included in the study. Of these, 12 underwent open rectal procedures and 22 underwent laparoscopic resections. Multiple parameters like duration of surgery, post-operative complications, postoperative stay, pathological T staging, lymph node yield, positive nodes, distal resection margins, circumferential radial margins were compared.Results: Operating time was significantly shorter in open procedure than laparoscopic surgery in both rectal resection and right hemicolectomies. The postoperative stay was significantly shorter in laparoscopic right hemicolectomy compared to open procedure. All other parameters like post-operative complications, T stage, lymph node yield, positive nodes, distal resection margins and CRMs were comparable in both groups. The lymph node yield was similar in upfront and post neoadjuvant carcinoma rectum cases.Conclusions: Laparoscopic colorectal resections have similar rates of complication, with shorter hospital stays with no compromise on oncological clearance with respect to lymph node yield, CRMs, distal resection margins compared to open procedures.

SUMMARY The purpose of this study was to assess the oncological outcomes of a large multicenter series of left thoracoabdominal esophagectomies, and compare these to the more widely utilized Ivor–Lewis esophagectomy. With ethics approval and an established study protocol, anonymized data from five centers were merged into a structured database. The study exposure was operative approach (ILE or LTE). The primary outcome measure was time to death. Secondary outcome measures included time to tumor recurrence, positive surgical resection margins, lymph node yield, postoperative death, and hospital length of stay. Cox proportional hazards models provided hazard ratios (HR) with 95% confidence intervals (CI) adjusting for age, pathological tumor stage, tumor grade, lymphovascular invasion, and neoadjuvant treatment. Among 1228 patients (598 ILE; 630 LTE), most (86%) had adenocarcinoma (AC) and were male (81%). Comparing ILE and LTE for AC patients, no difference was seen in terms of time to death (HR 0.904 95%CI 0.749–1.1090) or time to recurrence (HR 0.973 95%CI 0.768–1.232). The risk of a positive resection margin was also similar (OR 1.022 95%CI 0.731–1.429). Median lymph node yield did not differ between approaches (LTE 21; ILE 21; P = 0.426). In-hospital mortality was 2.4%, significantly lower in the LTE group (LTE 1.3%; ILE 3.6%; P = 0.004). Median hospital stay was 11 days in the LTE group and 14 days in the ILE group (P < 0.0001). In conclusion, this is the largest series of left thoracoabdominal esophagectomies to be submitted for publication and the only one to compare two different transthoracic esophagectomy strategies. It demonstrates oncological equivalence between operative approaches but possible short- term advantages to the left thoracoabdominal esophagectomy.

Abstract Background Lymph node yield is an important prognostic factor in head and neck squamous cell carcinoma. Variability in neck dissection sampling techniques has not been studied as a determinant of lymph node yield. Methods This retrospective study used lymph node yield and average nodes per level to compare level-by-level and en bloc neck dissection sampling methods, in primary head and neck squamous cell carcinoma cases operated between March 2017 and February 2020. Results From 123 patients, 182 neck dissections were analysed, of which 133 were selective and the rest were comprehensive: 55 had level-by-level sampling and 127 had undergone en bloc dissection. The level-by-level method yielded more nodes in all neck dissections combined (20 vs 17; p = 0.097), but the difference was significant only for the subcohort of selective neck dissection (18.5 vs 15; p = 0.011). However, the gain in average nodes per level achieved by level-by-level sampling was significant in both groups (4.2 vs 3.33 and 4.4 vs 3, respectively; both p < 0.001). Conclusion Sampling of cervical lymph nodes level-by-level yields more nodes than the en bloc technique. Further studies could verify whether neck dissection sampling technique has any impact on survival rates.

IntroductionLymph node retrieval and quantification is an important element in staging upper gastrointestinal cancers. Our department introduced fat clearance for oesophagectomy and gastrectomy specimens in 2014. This study assessed the impact of this change on lymph node yield and upstaging.MethodsWe reviewed histopathology data for upper gastrointestinal resection specimens. Patient demographics, clinical, macroscopic and microscopic data were compared with a historical cohort who did not undergo fat clearance.ResultsOf 158 patients, 133 resection specimens received fat clearance resulting in a significantly higher lymph node yield than the historical cohort (22 vs 13 lymph nodes, p<0.0001). Fat clearance found additional positive nodes in 24.1% of patients and increased the number of cases achieving a minimum node yield of 15. Nodes found by fat clearance caused upstaging in 15% of the cohort.DiscussionFat clearance increases node yield in upper gastrointestinal resection specimens and may cause nodal upstaging.
