Congenital factor V (FV) deficiency is a rare hemorrhagic disorder that can cause excessive bleeding during and after surgery in the affected patient. This report is the case of a patient who had FV deficiency with recurrent posthemorrhoidectomy bleeding treated with the hemostatic procedure and fresh frozen plasma (FFP) transfusions. A 45-year-old male patient had previously undergone hemorrhoidectomy for multiple hemorrhoids at a local hospital. Hemorrhoidectomy was successful; however, he was transferred to our hospital for evaluation of the origin of the recurrent posthemorrhoidectomy bleeding and underwent a hemostatic procedure. This bleeding was treated with coagulation using electrocautery, multiple sutures, and FFP transfusion (1,600 mL/day) for 7 consecutive days. The patient’s plasma FV activity was 23%. Early detection of clotting factor deficiency in patients with hemorrhagic events after surgical treatments may prevent unnecessary procedures such as reoperations and minimize the cost of replacement therapy such as large-volume FFP transfusion.

Purpose:
Rectal prolapse is a benign disease in which the rectum protrudes below the anus. Although many studies have been reported on the treatment of primary rectal prolapse for many years, there is a lack of treatment or clinical research results on recurrent rectal prolapse. This study aimed to evaluate the outcomes of surgical approaches for recurrent rectal prolapse.
Methods:
We studied patients who underwent surgical treatment for recurrent rectal prolapse disease from March 2016 to February 2021. We analyzed the previous operation methods in patients with recurrent rectal prolapse, as well as the operation time, complication rate, hospital stay, and re-recurrence rates in the perineal and abdominal approach groups.
Results:
Out of a total of 239 patients, 41 patients who underwent surgery for recurrent rectal prolapse were retrospectively enrolled. Recurrent rectal prolapses were surgically treated either by the perineal approach (n = 25, 61.0%) or by the abdominal approach (n = 16, 39.0%). The operation times were significantly longer in the abdominal approach than in the perineal approach (98.44 minutes vs. 58.00 minutes, P = 0.001). Hospital stay was significantly longer in the abdominal approach than in the perineal approach (9.19 days vs. 6.00 days, P = 0.012). Re-recurrence rate after repeat repair was not significantly different between the 2 groups (P = 0.777).
Conclusion
Although the perineal approach shortened the operation time and hospital stay, there were no significant differences between the 2 groups in postoperative complications and re-recurrence rate. Both approaches can be good surgical options for the treatment of recurrent rectal prolapse.

Annals of Coloproctology 2020;36(3):186-191
Purpose:
There is a concern that enhanced recovery after surgery may affect other proposed quality measures, including the rate of readmission due to early discharge. We examine the 30-day readmission rate, risk factors associated with readmission after elective colorectal surgery for colon cancer, causes of readmission, disease-free survival (DFS), and overall survival (OS) in a single institution.
Methods:
We retrospectively investigated 292 patients who underwent elective colorectal surgery for colon cancer between 2010 and 2015. Baseline data including age, sex, body mass index, American Society of Anesthesiologists physical status classification, preoperative comorbidities, previous operation history, TNM stage, surgical approach, operation time, gas passage time, and length of hospital stay were obtained. Univariate and multivariate logistic regression analyses were performed to identify risk factors associated with 30-day readmission.
Results:
A total of 229 patients who underwent elective colorectal surgery were enrolled. Twenty-four patients were readmitted 30 days after discharge. The most common readmission diagnoses were wound bleeding or surgical site infection. Multivariate analysis indicated that patients who had preoperative hepatic disease were at the highest risk of readmission (odds ratio [OR], 8.98; 95% confidence interval [CI], 7.35–10.61). Survival outcomes were significantly better in the nonreadmitted group (OS, P=0.00; DFS, P=0.04).
Conclusion
This study identified that preoperative comorbidities including hepatic and pulmonary diseases were associated with higher readmission rates after elective colorectal surgery. Moreover, the most common cause of readmission in patients who underwent elective colorectal surgery was wound bleeding or surgical site infection.
6.Laparoscopic approach in the surgical treatment of large retrorectal tumors: a short-term experience at a single tertiary center case series in Korea

Retrorectal tumors, although rare, pose diagnostic and treatment challenges due to their nonspecific symptoms and complex anatomical location. This single-center case series reports short-term outcomes of laparoscopic transabdominal resection as a surgical approach for large retrorectal tumors. Between 2017 and 2020, five patients underwent this procedure. The median patient age was 53.2 years (range, 34–60 years), and the median operating time was 130 minutes (range, 95–205 minutes). All tumors were located in the retrorectal space. The median tumor size was 5.8 × 4.3 cm (range, 3.5–7.5 cm). Biopsy results included epidermoid cysts, tailgut cyst, lipoma, and keratinous cyst. The median hospital stay was 7.8 days (range, 5–11 days), and the median follow-up duration was 78.0 days (range, 14–219 days). One patient developed a postoperative surgical site infection. Overall, laparoscopic transabdominal resection appears to be a minimally invasive and effective treatment option for retrorectal tumors.

BACKGROUND: A randomized, multicenter, open-label, parallel group study was performed to compare the effects of remifentanil and morphine as analgesic drugs on the duration of weaning time from mechanical ventilation (MV). METHODS: A total of 96 patients with MV in 6 medical and surgical intensive care units were randomly assigned to either, remifentanil (0.1-0.2 mcg/kg/min, n = 49) or morphine (0.8-35 mg/hr, n = 47) from the weaning start. The weaning time was defined as the total ventilation time minus the sum of controlled mode duration. RESULTS: Compared with the morphine group, the remifentanil-based analgesic group showed a tendency of shorter weaning time (mean 143.9 hr, 89.7 hr, respectively: p = 0.069). Secondary outcomes such as total ventilation time, successful weaning rate at the 7th of MV day was similar in both groups. There was also no difference in the mortality rate at the 7th and 28th hospital day. Kaplan-Meyer curve for weaning was not different between the two groups. CONCLUSIONS: Remifentanil usage during the weaning phase tended to decrease weaning time compared with morphine usage.
