RESUMO
INTRODUCTION: Laparoscopic colorectal surgery is being widely practiced with an excellent short-term and equal long-term results for colorectal diseases including cancer. However, it is widely believed that as the experience of the surgeon/unit improves the results get better. This study aims to assess the pattern of case selection and short-term results of laparoscopic colorectal surgery in a high volume centre in two different time frames. MATERIALS AND METHODS: This study was done from the prospective data of 265 elective laparoscopic colorectal resections performed in a single unit from December 2005 to April 2011. The group was subdivided into initial 132 patients (Group 1) from December 2005 to December 2008 and next 133 patients (Group 2) between December 2008 and April 2011 who underwent laparoscopic colorectal resections for cancer. The groups were compared for intraoperative and perioperative parameters, type of surgery, and the stage of the disease. RESULTS: The age of patients was similar in Groups 1 and 2 (57.7 and 56.9, respectively). Patients with co-morbid illness were significantly more in Group 2 than in Group 1 (63.2% vs. 32.5%, respectively, P≤0.001). There were significantly more cases of right colonic cancers in Group 1 than in Group 2 (21.9% vs. 11.3%, respectively, P<0.02) and less number of low rectal lesions (20.4% vs. 33.8%, respectively, P≤0.02). The conversion rates were 3.7% and 2.2% in Groups 1 and 2, respectively. The operating time and blood loss were significantly more in Group 1 than in Group 2. The ICU stay was significantly different in Groups 1 and 2 (31.2± 19.1 vs. 24.7± 18.7 h, P≤0.005). The time for removal of the nasogastric tube was significantly earlier (P=0.005) in Group 2 compared to Group 1 (1.37± 1.1 vs. 2.63±1.01 days). The time to pass first flatus, resumption of oral liquids, semisolid diet, and complications were similar in both groups. The hospital stay was more in Group 1 than in Group 2 ( P≤0.01). The numbers of lymph nodes retrieved was similar in both groups. The T stage of the disease in Groups 1 and 2 were similar, however, the number of T4 lesions was significantly more in Group 2 (8.3% vs. 18.7%, respectively, P<0.01). CONCLUSION: This study shows that with increasing experience, laparoscopic colorectal surgery can be practiced safely with minimal conversion rates and morbidity. As the units experience improves, there is a trend towards selecting advanced cases and performing complex laparoscopic colorectal procedures. With increasing experience, there is a trend towards better short-term outcome after laparoscopic colorectal surgeries.

Dense inflammatory reactions, loss of tissue planes and sepsis make surgical treatment of diverticulitis complex and difficult. Experience with laparoscopic management of this disease is scanty in our country. This study aims to assess the pattern of presentation, the site of involvement and complications of diverticulitis coli. This study also aims to audit the results of laparoscopic approach for complicated colonic diverticulitis. A retrospective analysis of all patients who had laparoscopic management of complicated diverticulitis patients from August 2007 to October 2014 was done from the database. The site of involvement, extent and presence or absence of complications of diverticular disease was noted. The surgical approach, intraoperative parameters and short-term outcome measures were analysed. There were 38 (8.8 %) patients with diverticular disease out of 427 patients who had laparoscopic colorectal surgery in the study period with a median age of 59 years. Out of 38 patients, 50 % had comorbid conditions. Internal fistulae were seen in 9 (23.6 %) patients, 6 with colovesical and 3 with colovaginal fistulae. Elective laparoscopic colectomy with primary anastomosis was done in 34 (89 %) cases of which, and 10 (26 %) patients had abscess on presentation requiring drainage. Four patients required emergency laparoscopic surgery of which primary resection and anastomosis was done in 3 (7.8 %), and Hartmann's operation was done in 1 (2.6 %) patient. Two patients required stoma. The morbidity was seen in 15 % cases, and the mean hospital stay was 9.54 days. Laparoscopic approach for diverticular disease and its complication is feasible and safe. Careful selection of patients, judicious use of diverting stoma and appropriate selection of the procedure help to achieve good results even in those with septic complications and fistulising disease.
