We aimed to evaluate the short-term outcome of colorectal resection in very elderly patients, aged 85 years or older. As the population ages, the number of elderly patients with colorectal cancer (CRC) is increasing in Japan. At this time, it is unclear whether or not laparoscopic colorectal resection is safe for this very elderly patient population. From January 2005 to November 2014, a total of 20 patients aged 85 years or older underwent laparoscopic colorectal resection at Osaka University Hospital. Pre- and postoperative clinical data and outcomes were collected retrospectively. There were no intraoperative or postoperative deaths. In 2 cases, the laparoscopic procedure was converted to open surgery. Postoperative complications occurred in 6 patients. Two patients developed an infection at the surgical site. Among the 4 patients who underwent low anterior resection (LAR), 2 experienced postoperative anastomotic leakage. Two other patients developed a lung infection and urinary tract infection, respectively. Laparoscopic colectomy for very elderly patients with CRC appears to involve tolerable risk. However, special caution is advisable for patients who may undergo LAR.

Paraduodenal hernia is traditionally repaired via conventional laparotomy. Recently, several reports described the repair of paraduodenal hernia via laparoscopic surgery with multiple ports. Due to development of the technique and devices for laparoscopic surgery, single-incision laparoscopic surgery (SILS) has been applied to various operations, including cholecystectomy, appendectomy, and procedures for colorectal cancer. Here, we report treatment of a left paraduodenal hernia via SILS. A 23-year-old man presented with abrupt onset of abdominal pain, nausea, and vomiting. Computed tomography revealed a mass of intestinal loops enveloped by a thin capsule on the left of the abdominal cavity. Blood circulation in the jejunal loops was preserved, and no dilatation of the jejunum was observed. Physical and radiographic examination indicated the possibility of left paraduodenal hernia; we performed paraduodenal hernia repair using SILS. After we confirmed that there was no strangulation or gangrenous change in the bowel on laparoscopic examination, we reduced the incarcerated jejunum loops via an atraumatic method. The postoperative course was uneventful, and the patient was discharged 8 days after the operation. This disease affects relatively young patients, rendering this operation attractive from the viewpoint of cosmetic benefits and minimal invasion. Paraduodenal hernia repair via SILS is feasible, safe, and may constitute an alternative method for paraduodenal hernia without necrotic change.
