RESUMEN
Objective@#To examine the effectiveness of non-operative of colonic fistula following acute pancreatitis.@*Methods@#Retrospective analysis of 354 patients with acute pancreatitis who were admitted to Department of Hepatobiliary Surgery of Chinese People′s Liberation Army General Hospital from January 2013 to December 2018. Age of the patients was (46±14) years (range: 14-85 years); 249 cases (70.3%) were males. There were 41 cases of acute edematous pancreatitis and 313 cases of acute necrotising pancreatitis. Two hundred and fifteen cases were diagnosed as moderate severe acute pancreatitis and 139 were diagnosed as severe acute pancreatitis. Among 313 cases of acute necrotising pancreatitis, 62 cases underwent non-surgical treatment, 251 cases underwent surgical treatment in which 218 of minimal access retroperitoneal pancreatic necrosectomy underwent percutaneous nephroliguectomy with peripancreatic necrotic tissue removal technique.@*Results@#There were 15 cases of colon fistula following acute necrotising pancreatitis, and the incidence rate was 4.2%(15/354). There were 7 males and 8 females, with age of (39±8) years (range: 27 to 50 years). The median interval between acute pancreatitis onset and diagnosis of colonic fistula was 71 days(27-134) days. Two cases occurred at the hepatic flexure of the colon, 4 cases at transverse colon, and 9 cases at splenic flexure of colon. Of the 354 patients, 39 cases died and the mortality was 11.0%. Two patients underwent laparotomy, and one of them died. The remaining 13 patients underwent non-surgical treatment and were discharged.@*Conclusion@#Acute pancreatitis with colonic fistula can be treated with non-surgical treatment and can achieve good prognosis.
RESUMEN
Objective To study the effect of combined laparoscopic and percutaneous nephroscopic necrosectomy in the treatment of peripancreatic abscesses.Methods The clinical data of 8 patients with peripancreatic abscesses treated by combined laparoscopic and percutaneous nephroscopic necrosectomy in our hospital from June 2015 to June 2017 were retrospectively analyzed.Results 8 patients were treated with percutaneous puncture and drainage under Ultrasonic / Computed Tomography guidance.Combined laparoscopic and percutaneous nephroscopic necrosectomy was then carried out.Two patients underwent percutaneous nephroscopic surgery twice and laparoscopic surgery once,and 3 patients underwent percutaneous nephroscopic surgery thrice,and 3 patients underwent percutaneous nephroscopic surgery 4 times and laparoscopic surgery once.One patient after percutaneous nephroscopic necrosectomy was complicated with sinus tract hemorrhage,which was treated by haemostasis through a small incision.Two patients who developed postoperative colonic fistula were treated successfully by conservative treatment.The average length of hospital stay was 80 d (60 ～ 153 d),and there was no death.Conclusion Combined laparoscopic and percutaneous nephroscopic necrosectomy was a minimally invasive and efficacious method to treat peripancreatic abscesses.
RESUMEN
Objective To compare the effects of ureteroscopic lithotripsy (URL), minimally invasive percutaneous nephrolithotomy ( MPCNL) , retroperitoneal laparoscopic ureterolithotomy ( RLU) and open ureterolithotomy (UL) for the treatment of complex upper ureteral calculi. Methods The data of 281 patients with complex upper ureteral calculi from January 2005 to January 2013 were retrospectively reviewed. 48 patients of them received treatment of URL, 113 patients received MPCNL, 67 patients received RLU and other 53 patients received UL. Results Success rates of treatment at the first time were:URL 62.5% (30/48), MPCNL 92.9%(105/113),RLU 100%(67/67) and UL 100%(53/53) . The mean blood losses during the operation were:URL (9.2 ± 1.4) mL,MPCNL (72.5 ± 5.8) mL,RLU (43.1 ± 8.5) mL and UL (100.5 ± 9.2) mL. The average operation time of URL group was shorter than three other groups, and the difference was statistically significant (P0.05) . Conclusion Clinical characteristics of patients and individual require ment should be considered comprehensively before an individual treatment choice is made for the treatment of complex upper ureteral calculi.
RESUMEN
Objective To evaluate the application of percutaneous nephroscopy in the treatment of upper urinary tract transitional cell carcinoma, particularly renal pelvic carcinoma. Methods From June 2006 to June 2010, eight cases (with 10 sides) of renal pelvic carcinoma received percutaneous nephroscopy tumor resection. There were six males (with 7 sides) and two females (with 3 sides) in the study group. There were six cases with solitary kidney and two cases with bilateral renal pelvic tumors. There were four cases with high-grade tumors and six cases with low-grade tumors. The age of patients ranged from 52 to 72 yrs (average 61.2 yrs). Tumor sizes ranged from 0.5 to 3.5 cm (average 2.6 cm). Patients were treated with laser or electrocautery through percutaneous nephroscopy. A ureteral stent was placed in the patients after the procedure. Chemotherapy was administered postoperatively through the nephrostomy tube. Results All the operations were successfully completed uneventfully. The operative time was 45-95 min (average 73 min), estimated blood loss was 20-300 ml (average 50 ml). No remarkable differences were found in serum creatinine levels before and after operation. After 10 to 36 mon. follow-up by CT, MRI, and ureteroscopy, one patient died of tumor metastasis and two patients had local tumor recurrence. The remaining patients had no local recurrence. Conclusions Percutaneous nephroscopy in treating renal pelvic tumor is safe and feasible. This is a better choice for the renal pelvic carcinoma patients who are unsuitable for ureteronephrectomy.
RESUMEN
Objective To explore the efficacy of transurethral nephroscopic pneumatic lithotripsy combined with ultrasound lithotripsy for bladder calculus.MethodsBy using transurethral F20.8 nephroscope and EMS LithoCaster,we performed transurethral nephroscopic pneumatic lithotripsy and ultrasound lithotripsy on 69 patients with bladder calculus(63 men and 6 women)between October 2005 and May 2008.The diameter of the calculi was ranged from 1.5 to 6.0 cm.Among the patients,42 had one stone in the bladder,while 27 had multiple calculi.Fifty-five patients were complicated with BPH,14 had neurogenic bladder,and 4 showed bladder diverticulum with stones in situ.Pneumatic frequency was set at 8-12 Hz,and ultrasonic energy was 50%-60%.For the patients with BPH electrovaporization ablation was plused.ResultsAmong the 69 patients,68 were cured in one session.The mean operation time was 25 minutes(15 to 40 minutes).One patient was converted to open surgery because of rupture of the bladder during the procedure.No patient had urethral stricture,infection,or massive hemorrhage during the operation.Follow-up was available in 68 patients for 6 to 10 months(mean,9 months).During the period,no recurrent calculi was found by ultrasonography and X-ray.ConclusionTransurethral nephroscopic pneumatic lithotripsy combined with ultrasound lithotripsy is effective for bladder calculus.
