We reported a case of irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.The patient complained about a right groin mass for more than 60 years with progressive enlargement for 3 years and pain for half a month.Abdominal CT examination at admission showed rectum and sigmoid colon hernia in the right inguinal area and thickening of sigmoid colon wall.Electronic colonoscopy and pathological diagnosis showed sigmoid colon cancer.Therefore,the result of preliminary diagnosis was irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.We converted laparoscopic exploration to laparotomy followed by radical sigmoidectomy and employed end-to-end anastomosis of descending colon and rectum in combination with repair of right inguinal hernia.The patient recovered well after operation and was discharged.

To evaluate the protection of proximal colon segment by analyzing blood supply disorder of proximal colon segment during laparoscopic proctosigmoidectomy(11 cases) in the Chaoyang Hospital of Capital Medical University. It is concluded that the disorder of blood supply of proximal colon segment during laparoscopic proctosigmoid surgery has two reasons. One is the anatomic factor of mesenteric vessels; the other is the inappropriate operative procedure. It is recommended that left colonic artery should be retained, and inferior mesenteric artery should be handled at a low level, thus, the risk of proximal intestine blood supply disorder caused by vascular anatomy variation can be reduced.

6.Application of sigmoid colon anatomy to laparoscopic surgery.
Chinese Journal of Gastrointestinal Surgery 2018;21(8):871-874
Laparoscopic sigmoidectomy for cancer is considered as a simple surgical approach, which is suitable for primary laparoscopic surgery. However, the success of laparoscopic sigmoidectomy is closely related to the anatomical characteristics of the sigmoid colon. The length, adhesion and morphology of the sigmoid colon vary greatly. The differences of the length, width, adhesion and morphology of the mesentery are large. The distribution of vessels is diversified. The high ligation or the low ligation is still controversial. The location of the sigmoid colon cancer is also not constant. These problems have great influence on the operation. Before operation, the tumor must be accurately located and the anatomical characteristics of the sigmoid colon must be fully evaluated. The operation can be carried out smoothly and the complications during and after the operation can be reduced.

PURPOSE: The aim of the present study was to evaluate the usefulness of indocyanine green (ICG) as a preoperative marking dye for laparoscopic colorectal surgery. METHODS: Between March 2013 and March 2015, 174 patients underwent preoperative colonoscopic tattooing using 1.0 to 1.5 mL of ICG and saline solution before laparoscopic colorectal surgery. Patients’ medical records and operation videos were retrospectively assessed to evaluate the visibility, duration, and adverse effects of tattooing. RESULTS: The mean age of the patients was 65 years (range, 34–82 years), and 63.2% of the patients were male. The median interval between tattooing and operation was 1.0 day (range, 0–14 days). Tattoos placed within 2 days of surgery were visualized intraoperatively more frequently than those placed at an earlier date (95% vs. 40%, respectively, P < 0.001). For tattoos placed within 2 days before surgery, the visualization rates by tattoo site were 98.6% (134 of 136) from the ascending colon to the sigmoid colon. The visualization rates at the rectosigmoid colon and rectum were 84% (21 of 25) and 81.3% (13 of 16), respectively (P < 0.001). No complications related to preoperative ICG tattooing occurred. CONCLUSION: Endoscopic ICG tattooing is more useful for the preoperative localization of colonic lesions than it is for rectal lesions and should be performed within 2 days before laparoscopic surgery.

Self-expandable metallic stents are widely used to relieve acute colorectal obstruction that's secondary to malignancy. They are utilized for both palliation and preoperative decompression prior to colorectal surgery. Although stents have been documented as a relatively safe therapeutic modality, procedure-related complications such as perforation, bleeding, stent reobstruction and migration can occur during or after colonic stent placement. Therefore, clinicians must be aware of the various complications associated with colonic stent placement. We present here a very rare case of sigmoidorectal intussusception that developed after fluoroscopic placement of a self-expandable metallic stent for preoperative decompression of sigmoid colon cancer. We misdiagnosed the intussusception as a distal stent migration on the plain radiography. On the sigmoidoscopic examination to evaluate the unrelieved colonic obstruction, we diagnosed a sigmoidorectal intussusception of the stent-implanted malignant tumor. The patient was successfully treated by laparoscopic partial reduction, followed by a curative anterior resection. This case demonstrates that careful examination must be done in cases of unrelieved colonic obstruction with suspicious stent migration, and intussusception must be considered as a rare complication of self-expandable metallic stent placement in the colon.

Anatomical shape of the mandibular ramus, which includes the area from the rear of the mandibular second molar to the mandibular posterior border and from the mandibular sigmoid notch to the inferior mandibular border, must be carefully considered to perform orthognathic surgery. The locations of the lingula and mandibular foramen in medial side of mandibular ramus are one of the most important factors to decide the location of the horizontal medial osteotomy in sagittal split ramus osteotomy and to select the line of vertical osteotomy in intraoral vertical ramus osteotomy. Sixty-five different Korean human dry mandibles were surveyed. All mandible have permanent dentition including complete eruption of the mandibular second molar. The locations of the lingula and mandibular foramen in medial side of the ramus were identified and following results were obtained. Anterior ramal horizontal distance from lingula was 16.13+/-3.53mm(range:8.6~24.3mm), anterior ramal horizontal distance from mandibular foramen was 23.91+/-4.79mm(range: 14.1~39.7mm), horizontal width of mandibular foramen was 2.79+/-0.95mm(range: 1.5 ~6.1mm), height of lingula was 10.51+/-3.84mm(range: 3.1~22.4mm), vertical distance from sigmoid notch to lingula was 19.82+/-5.11mm(range: 9.1~35.3mm). From this study, the result could be used to select the location of osteotomy lines and to decide amount of periosteal elevation to avoid injury of neurovascular bundle, and to accomplish the appropriate split in Korean patients in mandibular orthognathic surgery.
