INTRODUCTION: Laparoscopic dissection in the pelvis is still a challenge. A transanal approach to rectal dissection allows better visualization during the dissection of the rectum and the creation of an anastomosis. Although initially used for patients with rectal cancer, the transanal approach may also have benefits in the surgical treatment of ulcerative colitis (UC). The aim of this study was to describe our initial experience with transanal completion proctectomy and ileal pouch-anal anastomosis for UC...

Mediastinal seminoma is an uncommon tumor that accounts for 25% of primary mediastinal germ cell tumors, which in turn comprise fewer than 5% of all germ cell tumors. Although CT normally shows a solid, lobulated tumor, mediastinal cystic seminoma has rarely been described. Here, we report a 24-year-old man who presented with a mediastinal cystic tumor that was resected after an 18-month delay via video-assisted thoracoscopic surgery while in the supine position; the procedure involved lifting the chest wall with a subcutaneous Kirschner wire...

INTRODUCTION: Generally, laparoscopic colorectal surgery is performed with the patient in the lithotomy and rotated positions. The lithotomy position, however, is associated with intraoperative peripheral nerve injury (IPNI). We studied the relationship between patient positioning during laparoscopic colorectal surgery, contact pressure at the shoulder, and the occurrence of IPNI and tested a positioning protocol aimed at surgical safety in addition to maintenance of a good surgical field...

Gastrointestinal stromal tumors (GIST) in patients under 18 years of age are classified as pediatric GIST. Pediatric GIST are extremely rare, and there are no reports of laparoscopic-endoscopic cooperative surgery for these lesions. We report the use of non-exposed endoscopic wall-inversion surgery as a laparoscopic-endoscopic cooperative surgery-related procedure for the treatment of a pediatric GIST. The case involved a 17-year-old male patient who presented with anemia and was found to have a bleeding gastric tumor...

INTRODUCTION: The advantages of laparoscopic surgery for ventral hernia repairs are well documented, but its application for small paraumbilical hernias has been less studied. There is no consensus regarding the best technique. METHODS: All patients who had open (suture or mesh) and laparoscopic repair of primary paraumbilical hernia between September 2007 and September 2017 in a single center were identified. Hernial defects of 2 cm or less were included; recurrent hernias were excluded...

Esophageal schwannomas are extremely rare esophageal submucosal tumors. Herein, we report a case of simultaneous resection of left lung cancer and an esophageal schwannoma with video-assisted thoracoscopic surgery. An asymptomatic 74-year-old woman received a diagnosis of an esophageal submucosal tumor during the preoperative assessment of a left lung cancer. The esophageal submucosal tumor arose in the left wall of the lower esophagus, and the patient was diagnosed as having a schwannoma by endoscopic ultrasound-guided fine needle aspiration...

Laparotomy and reoperation remain the standard procedures for patients with suture line disruption after the initial surgical treatment for duodenal ulcer perforation has failed. Recently, endoscopic stents have been employed for dehiscence of the suture line after a surgical repair or even as a primary treatment. We present such a case, the fourth in the literature. In this case, a partially covered stent was placed to cover the duodenal perforation opening after an unsuccessful stitching 6 days earlier...

INTRODUCTION: Surgery for Child-Pugh B liver function is considered risky because of its high morbidity rate and the acceptable indication criteria for laparoscopic liver resection (LLR) for Child-Pugh B patients have not been identified. We conducted a retrospective cohort study to determine the optimal introduction of LLR for Child-Pugh B patients based on our single-institute experience. METHODS: A total of 17 Child-Pugh B patients underwent LLR between 2005 and 2017...

INTRODUCTION: The learning curve for totally extraperitoneal repair (TEP) is longer and steeper than that for transabdominal preperitoneal repair (TAPP) due to the preperitoneal view to which the surgeon is not accustomed and the limited working space. The aim of this study was to clarify the learning curve for SILS-TEP. METHODS: A retrospective analysis of 80 consecutive patients with unilateral inguinal hernia was performed. All patients underwent elective SILS-TEP performed by a single learning surgeon with a teaching assistant between July 2016 and March 2018 at Kinki Central Hospital...

Persistent mesocolon is an embryological anomaly of the colon resulting from failure of the primitive dorsal mesocolon to fuse with the parietal peritoneum. We herein present a case of laparoscopic high anterior resection for triple colorectal cancers with persistent ascending and descending mesocolons and a right-bound inferior mesenteric artery. Preoperative 3-D CT demonstrated that the sigmoid colon had shifted to the right abdomen and was located under the ascending colon. Moreover, the inferior mesenteric artery and vein traveled toward the right abdomen accompanied by the mesentery of the descending colon...

The safety and feasibility of 3-D laparoscopy-assisted bowel resection were demonstrated in the management of rectal cancer. However, this procedure's role in the management of patients with diffuse cavernous hemangioma of the rectum has not been evaluated. Here, two patients were diagnosed with diffuse cavernous hemangioma of the rectum by colonoscopy and abdominal imaging. One case underwent pull-through transection and coloanal anastomosis in 3-D laparoscopy-assisted surgery. In another patient, 3-D laparoscopy-assisted abdominoperineal resection was performed...

The early and accurate diagnosis of reduction en masse followed by proper treatment is important but has been difficult. Here, we report the case of a 58-year-old Japanese man who presented with abdominal pain and vomiting at a nearby clinic. He was referred to our hospital on suspicion of small bowel obstruction. Despite the total disappearance of his symptoms, the abdominal X-ray examination showed distended loops of small bowel. The preoperative diagnosis of small bowel strangulation due to an internal hernia was made by CT, and we therefore performed emergency exploratory laparoscopy...

INTRODUCTION: Laparoscopic surgery is widely performed in various surgical fields, but this technique requires time for surgeons to master. However, at the same time, there are many advantages in visualizing the operative field through a camera. In other words, we can visualize what we cannot see with our own eyes by using augmented reality and computer vision. Therefore, we investigated the possibilities and usefulness of computer vision in total laparoscopic hysterectomy. METHODS: This study was approved by the Mitsui Memorial Hospital ethics committee...

This case involved a 64-year-old female patient with a BMI of 35.3 kg/m2 and poorly controlled type 2 diabetes mellitus. Preoperative upper gastrointestinal endoscopy revealed chronic, atrophic gastritis. Helicobacter pylori antibody was negative. The patient underwent laparoscopic sleeve gastrectomy with duodenal-jejunal bypass as a metabolic surgery to treat obesity and type 2 diabetes mellitus. At 1 year postoperatively, routine endoscopy detected a flat elevated lesion at the distal gastric sleeve, near the posterior wall of the antrum; biopsy revealed adenocarcinoma...

Extra-adrenal paraganglioma is a rare form of neuroendocrine neoplasm capable of catecholamine secretion. The surgical risks associated with the tumor location are compounded in this case of a kyphotic patient. This report presents the successful application of laparoscopy on extra-adrenal paraganglioma located behind the Spiegel lobe in a kyphotic patient. The operation was performed after 1 week of α-blocker administration. The laparoscopic approach, with the patient in the left hemilateral decubitus position on a rotating table, provided optimal access for safe tumor resection after complete hepatic right lobe mobilization...

INTRODUCTION: The laparoscopic transabdominal preperitoneal approach requires peritoneal closure and technically skilled knotting. We have started to use a barbed running suturing device (V-Loc 180) without knotting for transabdominal preperitoneal repair of hernias. This study aimed to determine whether using V-Loc 180 was safe and shortened the time for laparoscopic peritoneal closure. METHODS: Between December 2010 and February 2017, 3-0 V-Loc 180 and a multifilament absorbable running suture (3-0 Vicryl) were used for three-port transabdominal preperitoneal repair of inguinal hernia in 363 cases...

INTRODUCTION: Laparoscopic colectomy with intracorporeal anastomosis is a minimally invasive surgical procedure for patients with colon cancer. However, there are often concerns about the presence of intraluminal exfoliated malignant cells in the intracorporeal anastomosis. This study investigated the relationship between colon cancer surgery and the incidence of intraluminal exfoliated malignant cells and several factors. METHODS: Eighty-nine consecutive patients who underwent either laparoscopic or open colectomy were prospectively studied in our department between 2007 and 2011...

Tailgut cyst is an uncommon developmental anomaly arising from the embryonic hindgut in the retrorectal space. The patient frequently is asymptomatic or has vague perineal complaints that pose a diagnostic dilemma. Moreover, the patient is often misdiagnosed and therefore mismanaged. MRI is the investigation of choice for diagnosis. After the diagnosis is established, complete surgical excision is required to alleviate patient discomfort and to prevent complications such as infection, malignant transformation, and recurrence...
