Value of preoperative biliary drainage on postoperative outcome after pancreaticoduodenectomy: A case-control study.

BACKGROUND/OBJECTIVE: The potential benefit of preoperative biliary drainage (PBD) on postoperative outcomes remains controversial. The aim of this study was to elucidate surgical outcomes of pancreaticoduodenectomy (PD) in patients with PBD and to show the impact of bilirubin level. METHODS: We retrospectively studied all patients who underwent PD in our center between January 2003 and June 2015. Patients were divided into: Group A (PBD) and Group B (no PBD). The primary outcome was the rate of postoperative complication. RESULTS: A total of 588 cases underwent PD. Group A included 314 (53.4%) patients while Group B included 274 (46.6%) patients. The overall incidence of complications and its severity were higher in Group A (p = 0.03 and p = 0.02). There was significant difference in the incidence of postoperative pancreatic fistula (p = 0.002), delayed gastric emptying (p = 0.005), biliary leakage (p = 0.04), abdominal collection (p = 0.04), and wound infection (p = 0.04) in Group A. The mean length of hospital stay was significantly longer in Group A than in Group B (12.86 ± 7.65 days vs. 11.05 ± 7.98 days, p = 0.01). No significant impact of preoperative bilirubin level on surgical outcome was detected. CONCLUSION: PBD before PD was associated with major postoperative complications and stent-related complications.

Tailored pancreatic reconstruction after pancreaticoduodenectomy: a single-center experience of 892 cases.

BACKGROUND: Pancreatic reconstruction following pancreaticoduodenectomy (PD) is still debatable even for pancreatic surgeons. Ideally, pancreatic reconstruction after PD should reduce the risk of postoperative pancreatic fistula (POPF) and its severity if developed with preservation of both exocrine and endocrine pancreatic functions. It must be tailored to control the morbidity linked to the type of reconstruction. This study was to show the best type of pancreatic reconstruction according to the characters of pancreatic stump. METHODS: We studied all patients who underwent PD in our center from January 1993 to December 2015. Patients were categorized into three groups depending on the presence of risk factors of postoperative complications: low-risk group (absent risk factor), moderate-risk group (presence of one risk factor) and high-risk group (presence of two or more risk factors). RESULTS: A total of 892 patients underwent PD for resection of periampullary tumor. BMI >25 kg/m2, cirrhotic liver, soft pancreas, pancreatic duct diameter <3 mm, and pancreatic duct location from posterior edge <3 mm are risk variables for development of postoperative complications. POPF developed in 128 (14.3%) patients. Delayed gastric emptying occurred in 164 (18.4%) patients, biliary leakage developed in 65 (7.3%) and pancreatitis presented in 20 (2.2%). POPF in low-, moderate- and high-risk groups were 26 (8.3%), 65 (15.7%) and 37 (22.7%) patients, respectively. Postoperative morbidity and mortality were significantly lower with pancreaticogastrostomy (PG) in high-risk group, while pancreaticojejunostomy (PJ) decreases incidence of postoperative steatorrhea in all groups. CONCLUSIONS: Selection of proper pancreatic reconstruction according to the risk factors of patients may reduce POPF and postoperative complications and mortality. PG is superior to PJ as regards short-term outcomes in high-risk group but PJ provides better pancreatic function in all groups and therefore, PJ is superior in low- and moderate-risk groups.

Intraoperative endoscopic retrograde cholangio-pancreatography: a useful tool in the hands of the hepatobiliary surgeon.

AIM: To evaluate the efficacy of intraoperative endoscopic retrograde cholangio-pancreatography (ERCP) combined with laparoscopic cholecystectomy (LC) for patients with gall bladder stones (GS) and common bile duct stones (CBDS). METHODS: Patients treated for GS with CBDS were included. LC and intraoperative transcystic cholangiogram (TCC) were performed in most of the cases. Intraoperative ERCP was done for cases with proven CBDS. RESULTS: Eighty patients who had GS with CBDS were included. LC was successful in all cases. Intraoperative TCC revealed passed CBD stones in 4 cases so intraoperative ERCP was performed only in 76 patients. Intraoperative ERCP showed dilated CBD with stones in 64 cases (84.2%) where removal of stones were successful; passed stones in 6 cases (7.9%); short lower end stricture with small stones present in two cases (2.6%) which were treated by removal of stones with stent insertion; long stricture lower 1/3 CBD in one case (1.3%) which was treated by open hepaticojejunostomy; and one case (1.3%) was proved to be ampullary carcinoma and whipple's operation was scheduled. CONCLUSION: The hepatobiliary surgeon should be trained on ERCP as the third hand to expand his field of therapeutic options.

Endoscopic management of postoperative bile duct injuries: a single center experience.

BACKGROUND/AIM: Biliary endoscopic procedures may be less invasive than surgery for management of postoperative bile duct injuries (POBDI). This retrospective work presents the experience of a single referral center during a period of 14 years in endoscopic management of POBDI. MATERIALS AND METHODS: Between 1994 (March) and 2008 (May), ERCP had been performed on 277 patients suspected to have POBDI. Patients shown to have complete transaction of bile duct were prepared for definitive surgery. For patients with simple biliary leak, sphincterotomy was performed with stenting. Pneumatic dilatation and stenting were done on patients with biliary stricture and preserved ductal continuity. ERCP was repeated every 3 months till the site of narrowing disappeared. RESULTS: The mean age was 45.3 years, 162 (58.5%) were females. The most common previous surgery was cholecystectomy (open, [N=119] 44%, and laparoscopic, [N=77] 28%). ERCP failed in 17 patients (6.1%). For successfully cannulated cases (N=260, 93.9%), the type of bile duct injury diagnosed at ERCP was completely ligated CBD (N=31/260 , 11.9%). Bile leakage was detected in (N=167/260, 64.2%) all patients with endoscopic sphincterotomy and stent insertion, the leak stopped in all of them. Biliary stricture was diagnosed in 33/260 patients (12.7%) and 17 of them had repeated balloon dilatation with stenting while the remaining had surgical correction. The success rate of endoscopic therapy for biliary strictures was 82%. Cholangiogram was normal in 29 patients (11.2%). CONCLUSIONS: Endoscopic therapy is safe and effective in the management of postoperative bile duct leak. For postoperative bile ductal strictures, ERCP is a less favorable option.

Outcome of pouch surgery for ulcerative colitis: single center experience.

AIM: The purpose of the present study is to present the experience and evaluate the outcome of pouch surgery for patients with ulcerative colitis (UC). METHODOLOGY: Fifty eight patients underwent surgery for UC between 1996 and 2007 at Mansoura Gastroenterology Center. A retrospective analysis has been done of all patients with UC undergoing surgery which includes details of the patient's history, indication of surgery, type of operation, postoperative morbidity, and functional outcome. RESULTS: The main indication for operation was failed medical treatment (n=42, 72.4%). Pouch surgery was performed in 25/58 patients (43.1%). The majority of patients, 23/25 (92%) had J-shaped pouch and most patients, 19 (76%), underwent a stapled anastomosis. Twenty patients (80%) had a defunctioning ileostomy. There was one postoperative death after pouch surgery. Early complications after pouch surgery included pelvic sepsis (n=4), small bowel obstruction (n=2), pouch hemorrhage (n=1), wound sepsis (n=3). Long-term follow-up data were available for 14 patients. The most common long-term complication was anastomotic stricture (n=9, 42.6%). Five patients (35.7%) presented with pouchitis. Median daytime stool frequency was 5.1. Three patients (21.4%) presented with fecal incontinence. CONCLUSION: Pouch surgery is a major one that attains many complications. However, the long term results and patient's satisfaction are reasonable.
