Laparoscopic appendectomy for complicated acute appendicitis.

The role of laparoscopic appendectomy in complicated appendicitis is still not widely accepted. The authors report their retrospective study performed to evaluate the effectiveness of the laparoscopic approach in the management of complicated appendicitis. From January 2003 to October 2008, 552 patients underwent appendectomy in our surgical department. Among these, 358 were not complicated appendicitis while 194 were complicated. Of the 194 cases of complicated appendicitis, 121 patients underwent laparoscopic appendectomy while the remaining 73 cases were treated by conventional open surgery. The average length of hospital stay was 5.7 days, with a range from 4 to 13 days. Post-operative complications were observed in a total 11 patients (9.1%), including 3 cases of intra abdominal abscess (2.5%), 2 cases of umbilical wound infection (1.6%) and 6 cases of prolonged ileus (4.9%). Our experience suggests that the laparoscopic procedure is a valid, safe and feasible option to manage acute complicated appendicitis.

[Radiological study of anastomotic leakages following colorectal surgery]. / Il controllo radiologico delle deiscenze anastomotiche in chirurgia colo-rettale.

The anastomotic leakage is one of the most serious complications following colorectal surgery. The incidence rate is between 3% and 21% considering the different experiences, pathology and surgical techniques. Our aim is to verify the role of radiological study in 45 patients with clinical and subclinical colorectal anastomotic leakage total anastomoses = 252). In 31 patients at risk, the operation was concluded with a loop ileostomy. The radiological study gastrografin enema was performed in all patients (26 symptomatic and 19 asymptomatic patients with loop ileostomy). The dehiscence incidence resulted 5.5%: 14 of 252 patients. In our experience the radiological study of selected colorectal anastomoses allowed to show the site and the flow of the leakage and to plan the proper management. In asymptomatic patients the study allowed to programme a specific follow up in patients with higher risk of postinflammatory stenosis or perhaps neoplastic relapse.

[Primary duodenal adenocarcinoma: report of three cases, prognostic factors and therapeutic approach]. / Adenocarcinoma primitivo del duodeno: tre casi clinici e considerazioni prognostico-terapeutiche.

Three cases of histologically proven primary non-ampullary adenocarcinoma of the duodenum, observed in our Department from 2001 to 2004, are described. The cases were treated by pancreaticoduodenectomy, duodenal resection and transduodenal excision, respectively. The rarity of this pathology is documented by few retrospective studies and justifies discussion about the main prognostic factors and the best therapeutic approach. We analyze diagnostic, therapeutic and prognostic factors after a revision of literature.

[Covered perforation of solitary cecal diverticulum: case report]. / Perforazione coperta di un diverticolo solitario del cieco: case report.

Acute right lower abdominal pain is often clinically difficult to diagnose. The diagnosis, especially in young patients, is frequently oriented to appendicular disease. Surgical exploration only confirms diagnosis or surprises the surgeon, revealing an unexpected right colon diverticulitis. This emergency condition challenges the surgeon with the dilemma about the best therapeutic choice: conservative or radical treatment? The elective localization of diverticulitis to the right colon is very rare (6.6-14%). The authors report a case of covered perforation of a solitary cecal diverticulum.

[Surgical timing in bleeding liver adenoma: case report]. / Timing chirurgico nell'adenoma epatico sanguinante: case report.

The diagnosis of liver adenoma, which etiopathogenesis most often involves a prolonged assumption of estrogen (90% of adenomas occurs in women after more than 5 years of estrogen therapy), always imposes a surgical resection. The reason depend from neoplasia characteristics like the malignant evolution (4%) and the high risk of abdominal/intratumoral bleeding (30-50%), that increases during pregnancy and postpartum period. Regression of lesion after discontinuation of hormone therapy is rare and does not remove the degeneration and/or haemorrhagic risk. Liver resection should be performed with appropriate selective endovascular embolization, considering that an inept emergency surgery may impose a greater risk ot the liver, exposing the patient to major risk of morbidity and mortality. The correct timing from embolization to elective surgery is not yet standardized in the literature. The surgeon's personal experience and mainly a careful patient follow-up suggest the timing of surgery after embolization. The authors relate their own experience about the therapeutic strategy and surgical timing in a case of bleeding liver adenoma.

[Pancreatic cancer. Analysis of 149 cases in our 17-year experience]. / Il carcinoma del pancreas. Analisi di 149 casi in 17 anni di esperienza.

The Authors analyse a series of 149 consecutive patients with carcinoma of the pancreas or the periampullary region. Curative surgical treatment was achievable in 55 patients, palliative procedures included surgery in 68 patients; biliary decompression with endoscopic or percutaneous procedure in 25 patients and chemotherapy in one patient with lymphoma. Perioperative complications consisted in gastroplegia (33%), pancreatic fistula (22%), biliary fistula (7.3%), abdominal abscess (5.5%) and hemoperitoneum (1.8%). Five patients died within 30 days after surgery (9%). The overall median postoperative survival was 37, 29 and 21 months in papillary, choledochal and pancreatic cancer, respectively.
