    Recently, complete laparoscopic procedures with intracorporeal reconstruction were performed in laparoscopic colectomies; however, they were scarcely reported in left-side colectomies because of the anatomical reasons. Since the descending colon is extensively fixed to the retroperitoneum, the dissection range required for resection cannot always be enough for a safe extracorporeal anastomosis. We devised an intracorporeal hemi-hand-sewn (IC-HHS) technique for end-to-end anastomosis in laparoscopic left-side colectomies. A total of 11 patients underwent IC-HHS anastomosis for the treatment of colon cancer around the sigmoid-descending (SD) junction. The posterior wall of the anastomosis was constructed with a linear stapler and subsequently, the anterior wall was sutured with an intracorporeal hand-sewn technique. Perioperative outcomes were evaluated. IC-HHS reconstruction between the descending colon and sigmoid colon was performed in 11 cases. There were six males and five females with an average age of 66.5 years. The average body mass index was 26.1 kg/m2. The averages of the operation time and intraoperative blood loss were 181.2 min (range, 154 to 210 min) and 13.9 ml (range 5-30 ml), respectively. There were no perioperative complications except for one patient with a superficial surgical site infection. IC-HHS anastomosis was successfully performed for colon cancer around the SD junction with acceptable perioperative outcomes and there were no procedure-related complications, indicating its feasibility. IC-HHS anastomosis could eliminate unnecessary splenic flexure mobilization in left-side colectomies. IC-HHS anastomosis can be an optional reconstruction for totally laparoscopic colectomies.
