Laparoscopic Curative Resection for Right-Sided Colonic Tumors: Initial Experience From a Specialized Cancer Hospital of a Developing Country.

Introduction Laparoscopic colonic resection is increasingly becoming popular worldwide and aims to provide curative resection in addition to the inherent benefits of laparoscopic surgery. The aim of this study was to evaluate the long-term outcomes of laparoscopic right hemicolectomy in a Pakistani cohort of patients. Methods and procedures We retrospectively analyzed the medical records of all patients who presented to our hospital with the diagnosis of right-sided colon carcinoma from January 2010 to December 2018 and underwent laparoscopic right or extended right hemicolectomy. Demographics, operative findings, histopathology report, and follow-up of patients were recorded and the analysis was performed on Statistical Packages for the Social Sciences (SPSS) Version 20 (IBM Corp, Armonk, NY). Results Seventy-five patients were included, 56 (74.7%) of whom were males and 19 (25.3%) were females. The median age was 52 years (range 25-82 years). The median hospital stay was five days (Range 3-13 days). The median blood loss was 70 milliliters and the mean operative time was 195.5±77.6 minutes. Laparoscopic extended right hemicolectomy was performed in 23 (16.67%) patients and standard right hemicolectomy in 52 (83.33%) patients. Most (72%) of the patients had a pathological T3 tumor, and the majority (61.3%) of the patients had no nodal involvement (pN0). The mean number of lymph nodes removed was 20+8. The median numbers of involved lymph nodes were 1.14+2.19. All the patients had R0 resection. Postoperatively, two patients had pelvic collection, and there was no 30-day mortality. Local recurrence occurred in four patients and distant metastases were observed in nine patients. The median follow-up in our study was 40.5±18.35 months. The median disease-free survival was 42±2.17 months and the median overall survival was 44±2.16 months. Conclusion Our experience with laparoscopic right colon resections has confirmed the safety and feasibility of the procedure.
