Treatment of the pancreatic stump after DCP.

OBJECTIVE: With improvement in methods, mortality after duodeno-cefalo pancreatectomy (DCP) has decreased to 5% even if complication rate is still high (30-50%). The pancreatic fistula still occurs in 25-50% of cases. Various methods of treating pancreatic stump have been proposed aimed to improve this rate. PATIENTS AND METHODS: The AA, surgeons of suburban hospital, have performed in five years, 2009-2013, 12 DCP. The pancreatic anastomosis has been in all cases an end-to-end duct-to-mucosa pancreatic-jejunostomy. RESULTS: The prevalence of fistula has been 33% (4 cases, 3 grade A and 1 grade B according with ISGPF score). CONCLUSIONS: Soft pancreas and small size of pancreatic duct are recognized as the mayor factor of risk for pancreatic fistula. In these cases are usually preferred pancreatic-jejunostomy (PJ) and pancreatic-gastro-anastomosis (PG). Both techniques show advantages and disadvantages: some randomized and prospective studies have demonstrated the absence of significative differences respect to the prevalence of pancreatic fistulas. Whipple method has been the most often used reconstructive method: a single loop with bile-pancreatic anastomosis and gastro-pancreatic anastomosis in sequence. A careful evaluation of pancretic tissue and Wirsung size with the aim of choosing the most suitable technique and an accurate execution are the most effective methods to prevent pancreatic fistula,even considering particular setting as elderly patient or HIV infection.

Laparoscopic cholecystectomy: ultrasonic energy versus monopolar electrosurgical energy.

OBJECTIVE: Nowadays, laparoscopic cholecystectomy (LC) is undoubtedly considered the "gold standard" in the surgical treatment of symptomatic gallstones, gallbladder adenomas and acute cholecystitis. Among the alternative energy sources proposed (monopolar, bipolar electric scalpel, radiofrequency sealers) with the aim to dissect and/or seal, the ultrasonic energy has been frequently adopted, however without a widespread acceptance among surgeons for routine or emergency laparoscopic cholecystectomy. This study investigates the possible beneficial aspects of ultrasonic dissection and its efficacy in the closure of the cystic artery and duct. PATIENTS AND METHODS: Patients were retrospectively divided into 2 groups according to the instruments used for division of the cystic artery and duct as well as for dissection of the liver bed: 121 patients in whom dissection and coagulation were performed using monopolar coagulation and 43 patients who were all treated with the ultrasonically activated scalpel harmonic ACE (Ethicon Endo-Surgery) as the sole instrument used in the whole procedure. RESULTS: The mean operative time, was significantly shorter in the harmonic group than in the traditional group (35.36 + 10.15 min vs. 55.6+12.10 vs. respectively; p < 0.0001). The rate of gallbladder perforation was significantly higher in the traditional group than in the harmonic group 20.66% (25 patients) vs. 6.98% (3 patients), respectively; p < 0.05). Intraoperative volume blood loss was significantly more in the traditional group than in the HS group (29.32+14.21 vs. 12.41+8.22; p < 0.0001). The mean amount of postoperative drainage was not significantly different among the two group (18.41+6.54 vs. 15.96+8.69 ml, p > 0.05). No considerable visceral injury has been recorded in either group. The postoperative parameters observed included postoperative hospital stay and morbidity for each group. The hospital stay was not significantly shorter in harmonic group (48.15+4.29 vs. 49.06+2.94 h, p > 0.05). The overall morbidity rate was 14.02 % (not significant). CONCLUSIONS: The use of the harmonic scalpel shows some statistically significant advantages limited to a few intraoperative parameters. We conclude that a wider use of harmonic scalpel not offers such advantages to make it the reference technique.

An unique case of dyspareunia leading to the diagnosis of urachal cyst in a nulliparous 28-year-old woman.

Urachal cysts are usually asymptomatic. Symptoms, when present, are usually acute abdominal pain, fever, midline hypogastric tenderness, palpable mass, evidence of urinary infection or haematuria due to infection of the cyst. We report an unique case of dyspareunia and "abdominal fluid flowing feeling" caused by an urachal cyst in a 28 year-old nulliparous woman. Diagnosis was achieved by US and MRI. Cystography excluded any cyst-bladder communication. Laparoscopic surgery was performed without perioperative complications. Patient obtained immediate relief of symptoms still continuing at a 24 months follow up.
