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...

Thymolipoma is a rare disease among benign tumors. We herein report the case of a child who underwent thoracoscopic resection of a large thymolipoma. A 3-year-old boy was diagnosed with an anterior mediastinal solid tumor. Thoracic imaging revealed a fat density mass that was 8.0 × 5.0 × 3.5 cm in size. Given the MRI findings of the tumor, we suspected that the lesion was a teratoma. We decided to perform thoracoscopic exploration and, if possible, resection of the solid tumor sequentially. We successfully resected the tumor thoracoscopically...

Chronic pain after laparoscopic percutaneous extraperitoneal closure is very rare. Here, we report a case of chronic pain after laparoscopic percutaneous extraperitoneal closure in an adolescent patient with inguinal hernia who underwent open repair. A 15-year-old girl was diagnosed with a left indirect inguinal hernia, and laparoscopic percutaneous extraperitoneal closure was performed. However, 6 months later, after strenuous exercise, she developed localized pain around the hernia site. Her pain was well controlled by internal treatment but failed to completely resolve...

Controversy remains regarding the optimal resection approach for Siewert type II adenocarcinoma of the esophagogastric junction (EGJ). Furthermore, an esophageal diverticulum, although rare, can complicate surgical procedures. Herein, we report a case of EGJ adenocarcinoma with an esophageal diverticulum that was treated using the minimally invasive abdominal and left thoracic approach (MALTA). A 72-year-old man, with EGJ adenocarcinoma and an epiphrenic diverticulum on esophagogastroduodenoscopy underwent endoscopic submucosal dissection...

A 74-year-old man presented at our hospital with complaints of abdominal pain, nausea, and vomiting. He had undergone laparoscopic radical cystectomy and ileal conduit for urinary bladder cancer 1 month earlier. The patient had abdominal distention, resonant sounds on percussion, and diffuse abdominal tenderness without rebound or guarding. Abdominal CT revealed dilated jejunal loops herniated through a cord-like structure. Based on these findings, emergency surgery was performed, and intestinal dilatation into the space between the ureter, the ileal conduit, and the sacral bone was detected...

The cause of jejunojejunal intussusception, a rare complication after Roux-en-Y gastric surgery, remains unclear. Here, we present a case of retrograde jejunojejunal intussusception that occurred after laparoscopic distal gastrectomy with Roux-en-Y reconstruction. A 51-year-old woman who had undergone laparoscopic distal gastrectomy and Roux-en-Y reconstruction for early gastric cancer 6 years previously was admitted to our hospital with abdominal pain. Abdominal CT revealed the "target sign," and she was diagnosed as having small bowel intussusception...

Schwannomas are tumors originating from the Schwann cells of the peripheral nerve sheath. Only 1%-3% of schwannomas reportedly occur in the pelvis. In a 67-year-old man, a pelvic mass that was 52 mm in diameter was incidentally diagnosed during a preoperative CT evaluation for prostate cancer. Preoperative 3-D reconstruction CT showed that the feeding artery to the tumor originated from the internal iliac artery and the drainage vein from the internal iliac vein. Each vessel could be isolated, clipped, and cut with minimal bleeding...

Laparoscopic sleeve gastrectomy (LSG) has become the dominant bariatric procedure because of its reliable weight loss and low complication rate. Portomesenteric vein thrombosis (PMVT) after LSG is an infrequent complication that can lead to serious consequences. Here, we report a patient who presented with abdominal pain 11 days after LSG for the treatment of morbid obesity. Contrast CT of the abdomen revealed PMVT. The patient had liver cirrhosis, which is a major risk factor for PMVT. When LSG is performed on an obese patient with liver cirrhosis, careful attention must be paid to the onset of PMVT...

INTRODUCTION: Perforated peptic ulcer disease (PPU) is a condition subject to wide geographical variations in incidence. It remains a significant cause of morbidity and mortality, even in the era of Helicobacter pylori eradication and proton-pump inhibitor therapy. There is no clear consensus on whether laparoscopic or open approaches are superior, and with most studies in this area originating from Europe and Asia, Australian data addressing this issue are lacking. METHODS: This retrospective cohort study included all patients who underwent surgery for PPU within a hospital network in Australia...

We report herein a patient with an inguinoscrotal hernia containing the urinary bladder. The hernia was safely repaired using the laparoscopic transabdominal preperitoneal repair technique. A 76-year-old man was admitted to our hospital with abdominal pain, vomiting, and diarrhea. His scrotum was swollen to fist size. Abdominal CT showed herniation of the sigmoid colon and the bladder into the right inguinal region, and his abdominal pain was attributed to incarceration of the sigmoid colon; this was manually reduced...

Endoscopic submucosal dissection is an effective procedure for treating non-invasive colorectal tumors. However, in cases of severe fibrosis, endoscopic submucosal dissection may be technically difficult, leading to incomplete resection. Here, we describe the case of a 74-year-old man who had early rectal cancer along with severe submucosal fibrosis caused by prior local excision. Combination treatment with endoscopic submucosal dissection and transanal minimally invasive surgery successfully enabled complete resection...

Situs inversus totalis (SIT) is a rare congenital anomaly characterized by complete inversion of the thoracic and abdominal organs. Many intra-abdominal and vessel anomalies have been reported in association with SIT. However, there have been no reports on the use of laparoscopic radical nephrectomy with thrombectomy for renal vein thrombus, which is considered as a safe and feasible procedure, in patients with SIT. We herein present the case of an 80-year-old man with SIT who was preoperatively diagnosed with a right renal tumor and renal vein tumor thrombus...

New techniques have been developed to treat severe anastomotic strictures after rectal surgery. This report describes a new approach using transanal minimally invasive surgery for the treatment of complete anastomotic occlusion. A 49-year-old man presented with a completely occluded anastomosis after low anterior resection with temporary ileostomy for rectal cancer. The lumen was completely obstructed with a blind wall. A transanal surgical approach was used to treat the obstruction. Water-soluble radiopaque contrast medium was injected intraoperatively to identify the proximal lumen, and an incision was made by electrocautery until the luminal diameter was sufficient...
