A case report of splenic injury related to colonoscopy: Fortunately treated with conservative treatment.

Colonoscopy is a common procedure for screening of colon cancer. Although complications are rare, recently there have been reports of splenic injury associated with colonoscopy. Its causes are not clear.

Mucinous Carcinoma of the Breast: Clinicopathological Features and Long-term Prognosis in Comparison with Invasive Ductal Cancer; A Single Hospital's 30+-Year Experience.

Mucinous carcinoma (MC) of the breast is a rare and special type of malignancy, with a substantial amount of extracellular mucin. We compared the clinicopathological features and the long-term survival of MC patients with those of invasive ductal carcinoma-no special type (IDC-NST) patients, and we examined prognostic factors of MC. A total of 116 patients with mucinous carcinoma and 3,258 patients with IDC-NST who underwent surgery at our hospital (1977-2008) were enrolled.

Significance of Microcalcifications on Mammography in the Surgical Treatment of Breast Cancer Patients with a Preoperative Diagnosis of Ductal Carcinoma in Situ by Core Needle Biopsy.

To clarify the surgical outcomes of breast cancer patients with a preoperative diagnosis of ductal carcinoma in situ (DCIS) by core needle biopsy (CNB) (abbreviated as CNBDCIS), we retrospectively analyzed the cases of 131 patients with CNBDCIS who underwent surgery at Oomoto Hospital (32 total mastectomies, 99 conservative mastectomies). Our analysis of underestimation and predictors of invasive breast cancer of CNBDCIS revealed that the underestimation rate of CNBDCIS was 40.5% (53/131).

Impact of the surgical modality for axillary lymph node dissection on postoperative drainage and seroma formation after total mastectomy.

Background: The most common complications after total mastectomy with axillary lymph node treatment are prolonged drainage and seroma formation. The aim of this study was to find factors correlated with prolonged fluid discharge (prolonged drainage or seroma formation after 20th operative day or later), including surgical techniques or devices and clinical factors.

Patients And Methods: A total of 202 conclusive primary breast cancer patients underwent total mastectomy with axillary lymph node treatment between January 7, 2014 and June 20, 2018 at our hospital.

Diminished Gastric Resection Preserves Better Quality of Life in Patients with Early Gastric Cancer.

Using the Postgastrectomy Syndrome Assessment Scale (PGSAS)-45, we compared the surgical outcomes and the quality of life (QOL) between patients undergoing limited gastrectomies and those undergoing conventional gastrectomies. In Oomoto Hospital between January 2004 and December 2013, a total of 124 patients who met the eligibility criteria were enrolled. Using the main outcome measures of PGSAS-45, we compared 4 types of limited gastrectomy procedures (1/2 distal gastrectomy [1/2DG] in 21 patients; pylorus-preserving gastrectomy [PPG] in 15 patients; segmental gastrectomy [SG] in 26 patients; and local resection [LR] in 13 patients) with conventional gastrectomy (total gastrectomy [TG] in 24 patients and 2/3 or more distal gastrectomy [WDG] in 25 patients).

Predictors of postoperative complications in elderly and oldest old patients with gastric cancer.

Background: The incidence of gastric cancer has been increasing among elderly persons in Japan. This study aimed to clarify risk factors for postoperative complications in oldest old patients with gastric cancer.

Methods: One-hundred ninety patients more than 75 years old with gastric cancer underwent gastrectomy between 2000 and 2011.

Extraperitoneal colostomy in laparoscopic abdominoperineal resection using a laparoscopic retractor.

Although extraperitoneal colostomy is often performed to prevent postoperative parastomal hernia formation following an open abdominoperineal resection of lower rectal cancer, it has not been widely employed laparoscopically because of the difficulty associated with the extraperitoneal route. This paper describes a laparoscopic extraperitoneal sigmoid colostomy using the Endo Retract™ Maxi instrument. This surgical technique is easy, and helps to prevent the development of parastomal hernias.

Persisting ratio of total amylase output in drain fluid can predict postoperative clinical pancreatic fistula.

Background/purpose: A consistent predictor for pancreatic fistula (PF) development in the early period after pancreatic resection is still lacking.

Patients And Methods: A total of 54 consecutive patients undergoing pancreatic resection were enrolled between June 2007 and April 2010. Pancreaticoduodenectomy (PD) and distal pancreatectomy (DP) were performed in 38 and 16 patients, respectively.
