The branch retinal vein occlusion is the second most common retinal vascular disease after diabetic retinopathy. Complications such as macular edema, retinal neovascularization, vitreous hemorrhage, epiretinal membrane may be associated. But, the retinal detachment may occur rarely in BRVO patients. We studied the clinical features of retinal detachment associated with branch retinal vein occlusion. We reviewed the medical records of 15 retinal detachment patients associated with branch retinal vein occlusion. Mean age was 54.7 years old and 10 patients(66.7%) were female. Hypertension was associated in 13cases(86.7%). The duration between the development of BRVO and the development of retinal detachment was shorter than 4 years in all cases and shorter than 2 years in 9 cases(60.0%). Retinal break was identified in 14 cases(93.3%), among which 13 cases(92.2%) were located inside the lesion of branch vein occlusion. The epiretinal membrane was frequently combined 8 cases(53.3%). The preoperative laser photocoagulation was done in 4 cases(26.7%). The primary surgical procedures included scleral buckling in 8 cases(53.3%), pars plana vitrectomy in 6 cases(40.0%), and scleral buckling with pars plana vitrectomy in 1 case(6.7%). Three cases(20.0%) required reoperations. The postoperative complications included the progression of cataract in 6 cases(40.0%), iatrogenic retinal tear in 3 cases(20.0%), epiretinal membrane in 2 cases(13.3%), and proliferative vitreoretinopathy in 1 case(6.7%). The anatomic retinal reattachment was achieved in 14 cases(93.5%) and the visual recovery in 11 cases(73.3%).

PURPOSE: There are known differences in embryology, clinical symptoms, incidences, molecular pathways involved, and oncologic outcomes of right-sided and left-sided colorectal cancers. However, immunologic study has only been characterized for healthy adults. The present study was designed to identify differences in immune cell populations in patients with right-sided and left-sided colorectal cancers.METHODS: A total of 35 patients who underwent colorectal resection for cancer between November 2016 and August 2017 at a tertiary teaching hospital were enrolled in this study. Patients were excluded if they had a disease affecting their immune system. Populations of immune cells, including mucosal-associated invariant T (MAIT), gamma delta T, invariant natural killer T, T, natural killer, and B cells, were measured in the peripheral blood and cancer tissues using flow cytometry, and then assessed based on the origin of the colorectal cancer.RESULTS: Fifteen had right-side and 20 had left-side colorectal cancer. There were no significant differences between the 2 cohorts for patient characteristics including pathologic stage. Peripheral blood from patients with right-side colon cancers contained fewer MAIT (0.87% right-side vs. 1.74% left-side, P = 0.028) and gamma delta T cells (1.10% right-side vs. 3.05% left-side, P = 0.002). Although the group with right-side colorectal cancer had more MAIT cells in cancer tissues (1.71% vs. 1.00%), this difference was not statistically significant.CONCLUSION: There is a difference in population sizes of immune cells in blood between patients with right-sided and leftsided colon cancers. The immune cell composition was determined to be distinct based on embryologic origin.

A rectocele with a weakened rectovaginal septum can be repaired with various surgical techniques. We performed laparoscopic posterior vaginal wall repair and rectovaginal septal reinforcement without mesh using a modified transperineal approach. A 63-year-old woman with outlet dysfunction constipation complained of lower pelvic pressure and sense of heaviness for 30 years. Initial defecography showed an anterior rectocele with a 45-mm anterior bulge and perineal descent. Laparoscopic procedures included peritoneal and rectovaginal septal dissection directed toward the perineal body, rectovaginal septal suturing, and peritoneal closure. The patient started a soft diet the following day and was discharged on the 5th postoperative day without any complications. The patient had no dyschezia or dyspareunia, and no problem with bowel function; 3-month follow-up defecography showed a decrease in bulging to 18 mm. Laparoscopic posterior vaginal wall and rectovaginal septal repair is safe and feasible for treatment of a rectocele, and enables early recovery.

Retrorectal space tumors are rare, and so are frequently unrecognized, misdiagnosed, and mistreated. A 57-year-old man visited the outpatient clinic with the chief complaints of thin stool and lower pelvic heaviness. A smooth, round huge palpable mass on the right posterolateral rectal wall was detected and pelvic computed tomography showed a 7.8-cm cystic lesion in the right retrorectal space. Laparoscopic procedures were initiated with perirectal dissection for rectal mobilization. After fixation of the peritoneum and tying the rectum for intracorporeal traction, the rectum was mobilized to identify the cyst. The cyst was removed using an endo-bag, with completion of cyst dissection. The final pathologic diagnosis was a tailgut cyst, or retrorectal cystic hamartoma without evidence of malignancy. The patient was discharged without any complications. The patient had no dyschezia or problems with bowel function. Laparoscopic resection is a safe and feasible method for surgical treatment, even for bulky retrorectal tumors, with an early recovery period.

PURPOSE: Appendiceal tumoral lesions can occur as benign, malignant, or borderline disease. Determination of the extent of surgery through accurate diagnosis is important in these tumoral lesions. In this study, we assessed the accuracy of preoperative CT and identified the factors affecting diagnosis. METHODS: Patients diagnosed or strongly suspected from July 2016 to June 2019 with appendiceal mucocele or mucinous neoplasm using abdominal CT were included in the study. All the patients underwent single-incision laparoscopic cecectomy with the margin of cecum secured at least 2 cm from the appendiceal base. To compare blood test results and CT findings, the patients were divided into a mucinous and a nonmucinous group according to pathology. RESULTS: The total number of patients included in this study was 54 and biopsy confirmed appendiceal mucinous neoplasms in 39 of them. With CT, the accuracy of diagnosis was 89.7%. The mean age of the mucinous group was greater than that of the nonmucinous group (P = 0.035). CT showed that the maximum diameter of appendiceal tumor in the mucinous group was greater than that in the nonmucinous group (P < 0.001). Calcification was found only in the appendix of patients in the mucinous group (P = 0.012). Multivariate analysis revealed that lager tumor diameter was a factor of diagnosis for appendiceal mucinous neoplasm. CONCLUSION The accuracy of preoperative diagnosis of appendiceal mucinous neoplasms in this study was 89.7%. Blood test results did not provide differential diagnosis, and the larger the diameter of appendiceal tumor on CT, the more accurate the diagnosis.

PURPOSE: We assessed the feasibility of testis-sparing surgery in children with testicular tumors. MATERIALS AND METHODS: Twenty-five pediatric patients who had a testicular tumor were enrolled for retrospective analysis. Testis-sparing surgery was planned in the cases with clinical features that preoperatively suggested the tumors to be benign, which was later determined intraoperatively by frozen section examination. The preoperative-fetoprotein (AFP) and transscrotal ultrasound (US) were evaluated along with the final pathology. We reviewed the immediate and late surgical complications, as well as the tumor recurrence after surgery. RESULTS: Teratoma, epidermoid cyst, yolk sac tumor, and Leydig cell tumor accounted for finding in 40%, 32%, 24%, and 4% of the patients, respectively. Based on the preoperative US, 18 patients had benign-looking tumors. According to the age-matched AFP references, 17 patients showed normal ranges preoperatively. Out of 14 patients, whose US and AFP level suggested the tumors to be benign, 10 (71.4%) were eligible for testis- sparing surgery on retrospective review. Testis-sparing surgery was performed in 5 patients, who showed the same pathology in frozen sections (3 epidermoid cysts, 2 teratomas). None of the 5 patients exhibited perioperative complications, and no recurrence or atrophy was observed at a mean follow-up of 39.8 months. CONCLUSIONS: Out of 14 patients, whose US and AFP analyses were available, 10 (71.4%) were eligible for testis-sparing surgery. Testis-sparing surgery was done in five out of the 10 patients without any complication or recurrence. Testis-sparing surgery is a feasible option in children with testicular tumors if the AFP level is within a normal range and the US suggests benign characteristics.

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.
