Indocyanine green (ICG) fluorescence for intestinal blood flow has been reported, but application during laparoscopic surgery for incarcerated inguinal hernia has not been reported. Here, we report the case of a patient with an incarcerated inguinal hernia in whom the bowel was preserved after evaluation of intestinal blood flow with ICG fluorescence using PINPOINT®, a brightfield full-color, near-infrared fluorescence camera. A man in his 80s was diagnosed with incarcerated inguinal hernia and underwent laparoscopic surgery...

Congenital diaphragmatic hernia is very rare in adults. The first choice of treatment is surgery, but the optimal surgical method remains unclear. We performed laparoscopic surgeries for two types of congenital diaphragmatic hernias using a novel mesh coated with a chemically modified substance. The first patient was a 65-year-old man with a Bochdalek hernia without a hernial sac, and the other patient was an 80-year-old woman with a Morgagni hernia with a hernial sac. The short-term outcomes of both cases were good, and laparoscopic repair seems to be a useful strategy regardless of the presence or absence of a hernial sac...

We report a case of an internal hernia through a transverse mesocolon defect after laparoscopic distal pancreatectomy. The patient was a 58-year-old man with an intraductal papillary mucinous neoplasm of the pancreatic body who underwent laparoscopic distal pancreatectomy. During surgery, an approximately 5-cm defect in the transverse mesocolon was inadvertently made. The defect was not closed as it was thought to be large enough to preclude incarceration. However, the patient developed a bowel obstruction 2 months postoperatively...

A 20-year-old woman with a perineal alveolar soft part sarcoma was referred to our hospital. MRI showed that an irregular oval tumor occupied the perineum. The tumor was contiguous to the vagina, rectum, levator muscle, and pubis and was diagnosed as alveolar soft part sarcoma by transvaginal biopsy. Laparoscopy-assisted total pelvic exenteration combined with a pubic resection was performed, and an R0 resection with a wide margin was achieved. It is well known that only R0 resection improves the outcome of patients with localized alveolar soft part sarcoma...

INTRODUCTION: In laparoscopic or robotic surgery, surgeons cannot directly palpate lymph nodes (LN), which could be considered a shortcoming in that procedure. This study was performed to evaluate the importance of palpation diagnosis of LN metastasis in colorectal cancer surgery. METHODS: This study enrolled 408 patients who underwent curative resection for primary colorectal cancer in our department in 2014. The diameter of each manually dissected LN was measured, and the LN was then examined by palpation to determine whether it was metastatic based on its consistency...

We report on a 45-year-old man who presented with pain in the left leg, which he had had for 2 months. A contrast-enhanced CT scan displayed a 25-mm tumor in the lateral side of the left psoas muscle. For this suspected retroperitoneal tumor, we performed laparoscopic resection of the tumor, which was encapsulated by the funicular femoral nerve, using surgical scissors rather than a surgical energy device and preserved the normal fascicles wherever possible. Pathological examination indicated a benign ancient schwannoma arising from the femoral nerve...

INTRODUCTION: The aim of this study was to introduce and examine a modified mechanical end-to-side esophagogastrostomy method ("reverse-Tornado" anastomosis) in laparoscopy-assisted proximal gastrectomy. METHODS: Five patients with gastric cancer who underwent laparoscopy-assisted proximal gastrectomy were analyzed retrospectively. Esophagogastrostomy in the anterior wall was performed in three patients, and esophagogastrostomy in the posterior wall was performed in two patients...

INTRODUCTION: Clinical use of an adhesion barrier made of oxidized, regenerated cellulose, Interceed®, has been reported in the field of obstetrics and gynecology to help prevent adhesions between the peritoneum and the bowel in various types of operations. In gastrointestinal surgery, sodium hyaluronate/carboxymethylcellulose has been reported as an absorbable membrane to reduce postoperative adhesions. The present study was a prospective randomized controlled study to investigate the safety and usefulness of Interceed in laparoscopic colorectal surgery...

Port-site metastasis of hepatocellular carcinoma (HCC) is extremely rare, and only one case has been reported in the English-language literature. Contamination with malignant cells along the needle tract during percutaneous biopsy or radiofrequency ablation is a well-recognized cause of HCC recurrence. Here, we describe a case of port-site metastasis after laparoscopic liver resection of HCC. The patient, who had undergone laparoscopic partial resection of the left lateral segment of the liver 18 months earlier, was diagnosed with HCC...

Situs inversus totalis (SIT) is a rare congenital condition in which abdominal and thoracic organs are transposed from normal positions. Laparoscopy-assisted distal gastrectomy for situs inversus totalis is technically difficult and has rarely been reported. Here, we report the case of man in his 40s with situs inversus totalis and a preoperative diagnosis of stage IA gastric cancer (cT1b, cN0, cM0). We successfully performed laparoscopy-assisted distal gastrectomy with D1+ lymph node dissection and Billroth I reconstruction...

Multiple endocrine neoplasia type 2 (MEN2) is an autosomal-dominant cancer syndrome with major components of medullary thyroid carcinoma, pheochromocytoma, and hyperparathyroidism. MEN2B is the most aggressive and rarest of the MEN2 variants. Pheochromocytoma in MEN2 is virtually always located in the adrenal medulla, but MEN2-associated extra-adrenal pheochromocytomas (paraganglioma) are rare. A 59-year-old man who has been diagnosed with MEN2B consulted our hospital for surgical treatment of a 10-mm left adrenal mass and a 30-mm retroperitoneal mass...

A 53-year-old man was readmitted with abdominal distention 2 weeks after undergoing laparoscopic low anterior resection with para-aortic lymphadenectomy for advanced rectal cancer (T4aN1M0, Stage IIIb). Ultrasound revealed massive ascites, and paracentesis revealed chylous fluid with a markedly elevated triglyceride level (1762 mg/dL). Despite conservative management, the fistula remained on postoperative day 120. On percutaneous lymphangiography, the chylous leakage point was clearly visualized at the para-aortic site, and surgical intervention was planned...

Chilaiditi syndrome is defined as the interposition of the bowel between the liver and right diaphragm. It is a rare disease and may be difficult to diagnose and manage. Treatment for asymptomatic patients with Chilaiditi is usually conservative and does not require surgical intervention, but surgery may be necessary if conservative treatment fails. This report describes a rare case of Chilaiditi syndrome causing small bowel obstruction and corrected using laparoscopic surgery.

INTRODUCTION: An accurate assessment of the depth of tumor invasion in patients with colon cancer is an important part of the preoperative evaluation. Whether computed tomographic colonography (CTC) or optical colonoscopy (OC) is better to accurately determine tumor location and invasion depth has not been definitively determined. The aim of this study was to determine the diagnostic accuracy of tumor localization and tumor invasion depth of colon cancer by preoperative OC alone or combined with CTC...

INTRODUCTION: Endoscopic thyroidectomy is a well-established surgical technique that is mainly performed for benign thyroid disease. We considered that endoscopic surgery could also be widely indicated for the treatment of thyroid cancer. We herein describe our new bidirectional approach of video-assisted neck surgery (BAVANS) for complete central node dissection in endoscopic thyroid cancer surgery. METHODS: BAVANS involves two different directional pathways to the cervical lesion...

INTRODUCTION: To identify a colorectal cancer tumor site for surgery, preoperative endoscopic marking methods, such as India ink tattooing or clipping, are generally performed. However, India ink tattooing causes problems such as impaired surgical view because of adverse events, ink leakage into the peritoneal cavity, and peritonitis or adhesion ileus as a result of leakage. The clipping method requires checking by palpation, which is unsuitable for laparoscopic surgery. MATERIALS AND SURGICAL TECHNIQUES: We devised a preoperative marking method for colorectal cancer surgery (laparotomy) by applying the fluorescent dye indocyanine green...

INTRODUCTION: Intraperitoneal onlay mesh repair is a current technique for laparoscopic repair of ventral and incisional hernias. However, the placement of synthetic mesh intraperitoneally may potentially lead to mesh-induced complications such as adhesive intestinal obstruction, enterocutaneous fistula, or even mesh erosion into organs. Inspired by the concept of laparoscopic inguinal hernia repair, we developed a novel technique: preperitoneal onlay mesh repair (PPOM). This involves placing the mesh in the preperitoneal plane to help eliminate mesh-induced complications...

Laparoscopic surgery for the treatment of a ruptured visceral artery aneurysm is recognized as a challenging procedure. Here, we describe our experience with laparoscopic surgery to treat a ruptured aneurysm of the right gastric artery. A 72-year-old woman was diagnosed with intra-abdominal hemorrhage caused by a ruptured aneurysm of the right gastric artery. Transcatheter arterial embolization failed because the right gastric artery could not be cannulated. Therefore, we performed laparoscopic surgery. Using laparoscopy, we detected that the bleeding from the aneurysm had ceased; thus, the planned procedure was successful...

A solitary fibrous tumor is a ubiquitous mesenchymal fibroblastic tumor that was previously considered limited to the pleural cavity. Here, we report a rare case of a large solitary fibrous tumor of the mesorectum, which was successfully resected laparoscopically. A 56-year-old woman was referred to our hospital for a giant pelvic mass. Pelvic MRI showed a well-circumscribed mass, 12 cm in diameter, with heterogeneous signal intensity on T2 -weighted images. It was diagnosed as a benign mesorectal tumor of unknown origin...
