INTRODUCTION: Accidental gallbladder perforation frequently occurs during laparoscopic cholecystectomy and may increase the risk of infection. However, the necessity of antimicrobial prophylaxis for these patients is unclear. The aim of this study was to examine the clinical outcomes and necessity of antimicrobial prophylaxis after laparoscopic cholecystectomy with gallbladder perforation. METHODS: One hundred patients who underwent laparoscopic cholecystectomy were divided into two groups: patients with gallbladder perforation (Group A, n = 37) and patients without perforation (Group B, n = 63)...

INTRODUCTION: CT angiography has gained widespread acceptance for preoperative evaluation of blood supply in patients with colorectal cancer. However, there have been few reports that pertain to the splenic flexure, for which surgery is technically difficult. We used preoperative CT angiography and CT colonography to evaluate blood supply to the splenic flexure. METHODS: We defined the splenic flexure as the junction of the distal third of the transverse colon and the proximal third of the descending colon...

BACKGROUND: Intraoperative hypothermia is linked to postoperative adverse events. The use of warmed, humidified CO2 to establish pneumoperitoneum during laparoscopy has been associated with reduced incidence of intraoperative hypothermia. However, the small number and variable quality of published studies have caused uncertainty about the potential benefit of this therapy. This meta-analysis was conducted to specifically evaluate the effects of warmed, humidified CO2 during laparoscopy...

INTRODUCTION: Laparoscopic liver resection (LLR) has been widely performed throughout the world. Although prospective registry studies to clarify the safety of LLR have been feasible, no prior multicenter prospective study has addressed this issue. We have conducted a multicenter prospective cohort study to reveal the current status of LLR in Japan. METHODS: From April 2015 to March 2016, candidates for LLR were preoperatively enrolled at 12 institutions. The primary end-point was surgical safety, which was evaluated based on surgical factors and on short-term and midterm outcomes...

Laparoscopic-assisted abdominoperineal resection and en-bloc prostatectomy using the trans-sacral approach for locally invasive rectal cancer that invades only the prostate is useful in order to avoid total pelvic exenteration. The patient was a 63-year-old man with cT4b (prostate) N1M0, stage IIIC rectal cancer. Curative resection was performed. Histopathological findings did not indicate definitive invasion into the prostate gland. The patient was discharged from the hospital on postoperative day 32 with an anastomotic leak and a ureteral catheter...

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: Although endoscopic procedures for lumbar disc diseases have improved greatly, treating migrated disc herniation is still a challenging task. Because of anatomic limitations, a rigid endoscope cannot effectively reach the herniated nucleus pulposus (HNP) in the hidden zone. The purpose of this study was to describe the transpedicle approach for HNP in the hidden zone using the percutaneous endoscopic lumbar discectomy system and to demonstrate the clinical results. Materials and Surgical Technique: Under fluoroscopy, the percutaneous endoscopic lumbar discectomy cannula is placed on the superior articular process, and a trephine with a diameter of 7...

INTRODUCTION: Laparoscopic hepatectomy is difficult because surgeons must perform the transection using many (four and more) energy devices and without direct manual maneuvers. Here we introduce hepatic transection by the classical method with a few (two or three) energy devices. MATERIALS AND SURGICAL TECHNIQUE: We performed laparoscopic hepatectomy for 40 patients with hepatic tumor and liver dysfunction. For parenchymal transection, we used bipolar radiofrequency coagulation forceps connected to a voltage-controlled electrosurgical generator and ultrasonic dissector...

INTRODUCTION: We employed a safe approach during laparoscopic splenectomy by first mobilizing the pancreatic tail and then dissecting the splenic vessels at the splenic hilum before mobilizing the spleen. MATERIALS AND SURGICAL TECHNIQUE: Patients were placed in the lithotomy position, and only the upper body was twisted to the right side. Five trocars were placed. After the bursa omentalis was opened, an avascular layer was identified behind the pancreas. This avascular layer was bluntly dissected, and the pancreatic tail was isolated from the retroperitoneum...

INTRODUCTION: The intra-operative detection of hepatocellular carcinoma (HCC) by ultrasonography is indispensable for laparoscopic partial hepatectomy. However, it is occasionally difficult to localize an HCC on an ultrasound in chronic liver disease. Two cases of partial hepatectomy using hookwire marking under CT guidance are presented. MATERIALS AND SURGICAL TECHNIQUE: The location of the HCC was identified by CT scan, and the puncture site was determined. A hookwire system, made of a stainless steel hook, was used to localize the HCC...

INTRODUCTION: To minimize the resection of stomach tissue, especially for lesions close to the esophagogastric junction or pyloric ring, we developed laparoscopic wedge resection with the serosal and muscular layers incision technique (SAMIT) for gastric gastrointestinal stromal tumors. MATERIALS AND SURGICAL TECHNIQUE: SAMIT involves resection of the mucosal and submucosal layers and then an incision in serosal and muscular layers around the tumor. SAMIT is simple and does not require special devices...

We examined the feasibility of umbilical diverting ileostomy for overweight and obese patients with rectal cancer undergoing laparoscopic surgery. Four patients who were overweight or obese (BMI > 27 kg/m(2) ) were initially scheduled for the creation of a conventional loop ileostomy. Intraoperatively, however, this was considered too complicated because of thick subcutaneous fat, bulky mesentery, or both. Instead, patients received a diverting ileostomy with the placement of an umbilical stoma. All patients had protruding umbilical ileostomies...

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...
