Purpose: To explore a minimally invasive emergency solution for acute obstruction caused by rectal cancer in patients in whom rectal stents or drainage tubes cannot be placed under the guidance of conventional colonoscopy or digital subtraction angiography (DSA). Patients and Methods: Without anesthesia, analgesia, or sedation, the prostate resection endoscopy was inserted into the rectum through the anus, and the rectal space in which the tumor caused obstruction was searched with a certain flushing pressure until it crossed the area of obstruction to reach the proximal intestinal cavity. The drainage catheter or rectal stent was inserted through the sheath of the endoscope to relieve the acute obstruction and permit further cancer treatment. Results: In 31 patients in whom a drainage catheter or rectal stent could not be inserted using conventional colonoscopy or DSA guidance, placement of the catheter or stent into the proximal intestinal cavity was achieved in 28 patients, including drainage tube placement in 21 patients and rectal stent placement in seven patients. Three patients could not undergo placement because of their advanced age and poor general condition. The operative time ranged 15-40 min. Among the 28 patients whose obstruction was relieved, 23 patients underwent radical resection rectal cancer after 10-14 days, and five patients were discharged with stents because they were unwilling to receive further treatment. There were no postoperative complications. Conclusion: Transanal resection is a minimally invasive, effective, safe, and feasible emergency treatment for rectal cancer-associated obstruction.

Liposarcoma is a rare malignant tumor type and surgical resection is the gold standard treatment. The present study reported on the case of a 51-year-old woman who presented with a mass in the left upper abdomen. Computed tomography revealed a 32-cm giant retroperitoneal liposarcoma. Complete tumor resection was performed without the removal of other organs. Postoperative pathological examination indicated retroperitoneal well-differentiated liposarcoma and immunohistochemistry revealed S-100(-), MDM2(+), vimentin(+), CDK4(+), p16(+) and STAT6(+) results. The patient recovered well after the surgery. Complete tumor resection during the first surgery is key to cure liposarcoma. The present case report will be helpful for clinical oncologists to fully understand giant retroperitoneal liposarcoma and treat it accordingly.

Giant bladder stones are rare in younger patients. Herein, we report a case of acute renal failure in a 31-year-old male with a giant bladder stone. The patient presented with lower urinary tract symptoms and urinary retention with milky-white urine. An emergency suprapubic cystotomy was performed and an 11-cm oval, solid stone was removed. Post-operative creatinine levels progressively decreased to normal and the patient exhibited smooth urination and good recovery at follow-up. A comprehensive physical examination and thorough investigation of the patient's medical history are required during clinical evaluation, diagnosis and treatment, thus preventing misdiagnoses and ensuring prompt treatment.

Radical cystectomy is the gold standard treatment for muscular invasive bladder cancer. Bricker surgery is the most common technique used for urinary diversion; however, troublesome complications such as postoperative anastomotic stenosis or fistula may occur. The case of a patient who had a urinary fistula after Bricker surgery performed at our hospital, is described. The patient was successfully treated with continuous double-cannula negative-pressure drainage and avoided a second surgery. The patient recovered well and is on regular follow-up. This case highlights the importance of timely and relevant treatment for patients with postoperative urinary fistula to avoid more invasive surgery.

Vesicovaginal fistula is one of the most common types of female genitourinary fistulas encountered in clinical practice, and its treatment is determined by the disease characteristics and at the discretion of the attending physician. The present study describes a unique conservative approach to the management of vesicovaginal fistulas. A 56-year-old woman developed a vesicovaginal fistula after laparoscopic hysterectomy. A bilateral ureteral single-J tube drainage through suprapubic bladder puncture with indwelling catheterization was performed. Thus, urine diversion and bladder emptying were achieved. In addition, the healing of the vesicovaginal fistula was promoted and the trauma of open or laparoscopic surgery was avoided. This minimally invasive method is simple and convenient, has few complications, and may be used as an alternative method for treating vesicovaginal fistulas.
