PURPOSE: The circular stapled hemorrhoidectomy established by A. Longo involves reducing the mucous membrane prolapse and blocking the end branches of the upper hemorrhoidal artery through transverse incision of a suitable section of the mucosa between the rectum and the anal canal. This study was undertaken to determine the efficacy and the safety of a circular stapled hemorrhoidectomy by comparing it with a conventional Milligan-Morgan hemorrhoidectomy. METHODS: One hundred thirty (130) patients with prolapsed hemorrhoids underwent surgical treatment with either a conventional (n=66)(conventional group) or a circular stapled (n=64) (stapled group) hemorrhoidectomy. The operation time was recorded, and the resected specimen was examined. The patients assessed their postoperative pain. Time to first bowel movement, hospital stay, and postoperative complications were analyzed. All patients received follow-up examinations at the out-patient clinic, and the time to return to work and the degree of their satisfaction were checked. RESULTS: The stapled group had a shorter average operation time (19.2 min. vs 26.1 min., P=0.016). The postoperative pain score in the stapled group was significantly lower than it was in the conventional group (P<0.05). Time to first bowel movement and hospital stay were not significantly different between the groups. Return to work was significantly faster in the stapled group (6.5 days vs 15.8 days, P<0.05). The degrees of satisfaction for the two groups were similar, and postoperative complications in the two groups were both similar and acceptable (6.1% vs 11.0%, P>0.05). CONCLUSIONS: A circular stapled hemorrhoidectomy offers a significantly less painful alternative to the conventional technique and is associated with an earlier return to normal activity. However, the long-term outcome needs to be evaluated further.

A granular cell tumor (GCT) is an uncommon mesenchymal lesion that rarely occurs in the colon and the rectum. We describe the case of 51-year-old man with a 2-cm-sized rectal GCT 10 cm above the anal verge that was incidentally detected after a screening colonoscopy. Preoperative radiologic studies demonstrated a suspicious submucosal rectal mass with mesorectal fat infiltration, but without circumferential resection margin threatening, extramural vessel invasion, and regional lymph-node enlargement. The tumor was resected by using a transanal endoscopic operation (TEO) without immediate postoperative complications. The final pathology revealed that the tumor consisted of a GCT that had invaded the subserosa with clear margins. It had no other risk factors for malignancy according to Fanburg-Smith criteria. We systematically reviewed the English literature by using PubMed and Google Scholar. This report may be the first documented case in the literature to describe a TEO for a GCT that had invaded the subserosa in the rectum.

Four consecutive cases of a colonic stricture following a da Vinci robot-assisted ultra-low anterior resection (LAR) with coloanal anastomosis and diverting ileostomy for the treatment of rectal cancer are reported. The colonic strictures developed after early proximal colonic ischemia without anastomotic site leakage or disruption. All patients were treated with preoperative chemoradiation therapy. During the postoperative recovery period, patients developed colonic ischemia, presenting with a high, spiking fever, but without any symptoms of peritonitis. Patients were treated with conservative management (antibiotic therapy) and discharged after two weeks when in good condition. Several months after discharge, all four patients developed a long-segment colonic stricture from the anastomosis site to the distal colon. Management of the colon strictures, including the anastomotic site, involved colonic dilation with a Hegar dilator in an outpatient clinic for several months. The ileostomies in three patients could not be closed.

PURPOSE: Single-port laparoscopic surgery has been used increasingly in treatment of a variety of conditions, and one recently introduced technique is single-port laparoscopic total extraperitoneal (SPLTEP) hernia repair. The aim of this study was to evaluate the safety and technical feasibility of SPLTEP hernia repair without fixation of the mesh. METHODS: From June 2010 to October 2012, 112 consecutive patients underwent SPLTEP hernia repair. RESULTS: We performed 129 inguinal hernia repairs in 112 patients, 17 were bilateral and 95 unilateral. There were 107 indirect hernias (83.0%), 20 direct hernias, and 2 hernias had both of types. Successful SPLTEP hernia repair was performed in 110 patients, with two conversions to an open surgical approach. Median operative times for unilateral and bilateral hernias were 70 minutes (40~145 minutes) and 90 minutes (67~135 minutes), respectively, and the hospital stay was 1 day (1~5 days). Postoperative complications included 10 patients with wound seromas or hematomas, 2 with urinary retention, 4 with groin pain, and 1 with bleeding from the incision site. There were 3 early recurrences (2.4%) during a median follow-up period of 42 months (range, 6~55). CONCLUSION: SPLTEP inguinal hernia repair without fixation of the mesh is both safe and technically feasible, and provides acceptable operative outcomes. Conduct of a prospective randomized study with long-term follow-up is needed to confirm the benefit of this technique in patients with inguinal hernia.

PURPOSE: This study compared the perioperative and pathologic outcomes between an extralevator abdominoperineal resection (APR) in the prone position and a conventional APR. METHODS: Between September 2011 and March 2014, an extralevator APR in the prone position was performed on 13 patients with rectal cancer and a conventional APR on 26 such patients. Patients' demographics and perioperative and pathologic outcomes were obtained from the colorectal cancer database and electronic medical charts. RESULTS: Age and preoperative carcinoembryonic antigen (CEA) level were significantly different between the conventional and the extralevator APR in the prone position (median age, 65 years vs. 55 years [P = 0.001]; median preoperative CEA level, 4.94 ng/mL vs. 1.81 ng/mL [P = 0.011]). For perioperative outcomes, 1 (3.8%) intraoperative bowel perforation occurred in the conventional APR group and 2 (15.3%) in the extralevator APR group. In the conventional and extralevator APR groups, 12 (46.2%) and 6 patients (46.2%) had postoperative complications, and 8 (66.7%) and 2 patients (33.4%) had major complications (Clavien-Dindo III/IV), respectively. The circumferential resection margin involvement rate was higher in the extralevator APR group compared with the conventional APR group (3 of 13 [23.1%] vs. 3 of 26 [11.5%]). CONCLUSION: The extralevator APR in the prone position for patients with advanced low rectal cancer has no advantages in perioperative and pathologic outcomes over a conventional APR for such patients. However, through early experience with a new surgical technique, we identified various reasons for the lack of favorable outcomes and expect sufficient experience to produce better peri- or postoperative outcomes.

PURPOSE: By integrating intraoperative near infrared fluorescence imaging into a robotic system, surgeons can identify the vascular anatomy in real-time with the technical advantages of robotics that is useful for meticulous lymphovascular dissection. Herein, we report our initial experience of robotic low ligation of the inferior mesenteric artery (IMA) with real-time identification of the vascular system for rectal cancer using the Firefly technique. MATERIALS AND METHODS: The study group included 11 patients who underwent a robotic total mesorectal excision with preservation of the left colic artery for rectal cancer using the Firefly technique between July 2013 and December 2013. RESULTS: The procedures included five low anterior resections and six ultra-low anterior resections with loop ileostomy. The median total operation time was 327 min (226-490). The low ligation time was 10 min (6-20), and the time interval between indocyanine green injection and division of the sigmoid artery was 5 min (2-8). The estimated blood loss was 200 mL (100-500). The median time to soft diet was 4 days (4-5), and the median length of stay was 7 days (5-9). Three patients developed postoperative complications; one patients developed anal stricture, one developed ileus, and one developed non-complicated intraabdominal fluid collection. The median total number of lymph nodes harvested was 17 (9-29). CONCLUSION: Robotic low ligation of the IMA with real-time identification of the vascular system for rectal cancer using the Firefly technique is safe and feasible. This technique can allow for precise lymph node dissection along the IMA and facilitate the identification of the left colic branch of the IMA.

PURPOSE: Our aim to assess clinical significance of the relation between inferior mesenteric vein ligation and collateral blood supply (meandering mesenteric artery) to the splenic flexure with elaboration more in anatomical landmarks and technical tips. MATERIALS AND METHODS: We review the literature regarding the significance of the collateral vessels around inferior mesenteric vein (IMV) root and provide our prospective operative findings, anatomical landmarks and technical tips. We analyzed the incidence and pattern of anatomic variation of collateral vessels around the IMV. RESULTS: A total of 30 consecutive patients have been prospectively observed in a period between June 25-2012 and September 7-2012. Nineteen males and eleven females with mean age of 63 years. Major colorectal procedures were included. There were three anatomical types proposed, based on the relation between IMV and the collateral vessel. Type A and B in which either the collateral vessel crosses or runs close to the IMV with incidence of 43.3% and 13.3%, respectively, whereas type C is present in 43.3%. There was no definitive relation between the artery and vein. No intra or postoperative ischemic events were reported. CONCLUSION: During IMV ligation, inadvertent ligation of Arc of Riolan or meandering mesenteric artery around the IMV root "in type A&B" might result in compromised blood supply to the left colon, congestion, ischemia and different level of colitis or anastomotic dehiscence. Therefore, careful dissection and skeletonization at the IMV root "before ligation if necessary" is mandatory to preserve the collateral vessel for the watershed area and to avoid further injury.

PURPOSE: The aim of this study is to assess the effects of age on the short-term outcomes of a laparoscopic resection of colorectal cancer in elderly (> or =75 years old), as compared with younger (<75 years old), patients. METHODS: A retrospective analysis of patients who underwent laparoscopic surgery for colorectal cancer between January 2007 and December 2009 was performed. There were two groups: age <75 years old (group A) and age > or =75 years old (group B). The perioperative outcomes between group A and group B were compared. RESULTS: The study included 824 patients in group A and 92 patients in group B. The body mass index (BMI) and the American Society of Anesthesiologists (ASA) score were significantly different between group B and group A (BMI: 22.5 vs. 23.5, P = 0.002; ASA score: 1.88 vs. 1.48, P = 0.001). Mean operating times were similar between the groups (325.4 minutes vs. 351.6 minutes, P = 0.07). We observed a higher overall complication rate in group B than in group A (12.0% vs. 6.2%, P = 0.047), but the number of severe complications of Accordion Severity Classification > or =3 (those that required an invasive procedure) was not significantly different between the two groups (6.5% vs. 3.4%, P = 0.142). There was no significant difference in the length of hospital stay (13.0 days vs. 12.0 days, P = 0.053). CONCLUSION: Although the elderly patients had a significantly higher overall postoperative complication rate, no significant difference was seen in either the number of severe complications of Accordion Severity Classification > or =3 or in the length of hospital stay. A laparoscopic colorectal cancer resection in elderly patients, especially those aged 75 years or older, is safe and feasible.
