Effect of endoscopic surgical skill qualification system for laparoscopic rectal surgery: Japanese multicenter analysis.

Background: Laparoscopic rectal surgery is often technically difficult. The Endoscopic Surgical Skill Qualification System (ESSQS) was established in Japan as an objective measure of skill for laparoscopic surgeons. However, the advantages of the ESSQS qualification for laparoscopic rectal surgery have been limited.

Risk factors for infection of totally implantable central venous access ports among patients requiring port removal.

Background: Totally implantable central venous access ports, are required for various purposes, ranging from chemotherapy to nutrition. Port infection is a common complication. In many patients with port infection, the ports are removed because antibiotics are ineffective.

Long-term outcomes and early recurrence after resection for metachronous pulmonary metastases from colorectal cancer.

Purpose: Properly selecting patients for aggressive curative resection for pulmonary metastases (PMs) from colorectal cancer (CRC) is desirable. We purposed to clarify prognostic factors and risk factors for early recurrence after metachronous PM resection.

Methods: Clinical data of 151 patients who underwent R0 resection for metachronous PMs from CRC at two institutions between 2008 and 2021 were reviewed.

Mid-term outcomes of laparoscopic vs open colectomy for pathological T4 and/or N2 colon cancer patients: Multicenter study using propensity score matched analysis.

Objectives: We aimed to assess mid-term outcomes after laparoscopic surgery (LAP) vs open surgery (OP) for pathological T4 (pT4) and/or N2 (pN2) colon cancer.

Methods: We retrospectively reviewed 255 primary tumor resections for pT4 and/or pN2 colon cancer performed from 2015 to 2020 at six hospitals, divided into LAP (n = 204) and OP groups (n = 51). After propensity score matching to minimize selection bias, 47 matched patients per group were assessed.

[Warm autoimmune hemolytic anemia accompanied by metachronous double primary cancer].

In about half of the cases, autoimmune hemolytic anemia (AIHA) is secondary to an underlying disease, often due to paraneoplastic syndromes. Recently, the number of patients developing metachronous multiple primary malignant tumors (MPMTs) has been increasing due to the aging of the population and the longer survival times of those with malignant tumors. A 78-year-old woman was diagnosed with sigmoid colon cancer in May 2017 and with warm AIHA in October 2017.

Methods: This multicenter retrospective study included 1372 patients who underwent elective curative resection surgery for colon cancer between April 2016 and March 2020.

Persistent Descending Mesocolon as An Intraoperative Risk Factor in Laparoscopic Surgery for Left-Sided Colon and Rectal Cancer.

Introduction: Persistent descending mesocolon (PDM) represents a failure of fusion of the descending mesentery, leading to anatomical abnormalities. This study aimed to examine the effects of anatomical features of PDM on laparoscopic surgical outcomes.

Methods: Patient backgrounds, surgical outcomes, anatomical characteristics, and operative findings were retrospectively compared between 186 patients classified into PDM and non-PDM groups who underwent primary resection for left-sided colon and rectal cancer at our hospital from January 2019 to December 2020.

Safe laparoscopic resection of a giant schwannoma in the retroperitoneum using a fluorescent ureteral stent: a case report.

Schwannomas that occur in the retroperitoneal cavity are rare. We herein report a patient who underwent safe laparoscopic resection by using a preoperative 3D computed tomography (CT) image and a fluorescent ureteral stent during the surgery. A 47-year-old man presented with left lower abdominal pain.

Combined transabdominal and transperineal endoscopic pelvic exenteration for colorectal cancer: feasibility and safety of a two-team approach.

Purpose: Pelvic exenteration (PE) is a highly invasive procedure with high morbidity and mortality rates. Promising options to reduce this invasiveness have included laparoscopic and transperineal approaches. The aim of this study was to identify the safety of combined transabdominal and transperineal endoscopic PE for colorectal malignancies.

Effect of endoscopic surgical skill qualification system for laparoscopic multivisceral resection: Japanese multicenter analysis.

Background: The efficacy of laparoscopic multivisceral resection (Lap-MVR) has been reported by several experienced high-volume centers. The Endoscopic Surgical Skill Qualification System (ESSQS) was established in Japan to improve the skill of laparoscopic surgeons and further develop surgical teams. We examined the safety and feasibility of Lap-MVR in general hospitals, and evaluated the effects of the Japanese ESSQS for this approach.

Short- and long-term survival after curative resection for colorectal cancer in nonagenarian patients.

Background/objective: With increased life expectancy, the incidence of colorectal cancer in oldest-old patients has been rising. Advanced age is a risk factor for adverse outcomes after surgery. This study aimed to evaluate the short- and long-term outcomes of curative resection for colorectal cancer in nonagenarians.

Long-Term Prognosis after Surgery for Locally Recurrent Rectal Cancer: A Retrospective Study.

Objective: Resection is usually recommended for locally recurrent rectal cancer (LRRC) for which R0 resection is possible, but its suitability varies by individual patient risk. Here, we report outcomes of resected LRRC in our hospital.

A learning curve in using organ retractor for single-incision laparoscopic right colectomy.

Single-incision laparoscopic surgery (SILS) has the potential to improve perioperative outcomes, including less postoperative pain, shorter operation time, less blood loss, and shorter hospital stay. However, SILS is technically difficult and needs a longer learning curve. Between April 2016 and September 2019, a total of 198 patients with clinical stage I/II right colon cancer underwent curative resection.

Postoperative Complications Predict Long-term Outcome After Curative Resection for Perforated Colorectal Cancer.

The C-reactive protein to albumin ratio predicts postoperative complications in oldest-old patients with colorectal cancer.

Purpose: The C-reactive protein to albumin ratio (CAR) is a simple and useful score for predicting the outcomes of patients with various cancers. The aim of this study was to evaluate the CAR and short-term outcomes in oldest-old patients with colorectal cancer.

Methods: A total of 126 patients aged 85 years and older with colorectal cancer who underwent resection for primary colon cancer from April 2015 to December 2018 were included.

Possible involvement of HSP90-HSF1 multichaperone complex in impairment of HSP72 induction in the failing heart following myocardial infarction in rats.

It is generally accepted that an increase in the myocardial level of heat-shock protein 72 (HSP72) protects viable cardiac tissue against myocardial infarction (MI)-induced stress. However, the induction of HSP72 after exposure to heat shock (HS) is blunted in the failing rat heart following MI. The mechanisms underlying this impairment in the HSP72 induction ability of the failing heart are not yet clearly defined.

Assimilate translocation and expression of sucrose transporter, OsSUT1, contribute to high-performance ripening under heat stress in the heat-tolerant rice cultivar Genkitsukushi.

High temperature reduces the grain quality of rice, a situation likely to become more frequent because of global warming. We studied the effects of high-temperature stress on grain quality of heat-tolerant cultivar 'Genkitsukushi' and heat-sensitive cultivar 'Tsukushiroman'. When day/night temperatures were 31/26 °C from heading until maturity, the grain quality of 'Genkitsukushi' was rated at the first inspection grade (high quality), whereas 'Tsukushiroman' showed a remarkable increase in the percentage of white immature kernels (low quality).
