RESUMEN
PURPOSE: Bleeding during hepatectomy remains a major cause of mortality despite recent developments in surgical and anaesthetic techniques. To date there is no single surgical device that combines speed, efficient haemostasis and safety for the adjacent vital structures during parenchymal division. This article presents the Three Surgeon Technique (3ST), a novel method of parenchymal dissection for major hepatectomies and compare it with our standard radiofrequency ablation (RFA) - assisted technique. METHODS: 77 patients who underwent major liver resection were divided into two groups: 38 of them (group A) underwent 41 RFA-assisted liver resections and 39 (group B) underwent 41 hepatectomies with the 3ST. The data for the 3ST were prospectively collected and compared to the already collated RFA patient group. RESULTS: Blood transfusion was necessary in 28 and 13 patients in group A and B respectively (p=0.016), with an average of 1.7 and 0.6 units of red blood cells (p<0.001). The Pringle maneuver was not required with the 3ST. The mean time of parenchymal dissection was 90.49 and 77.52 min in group A and B, respectively (p=0.007). CONCLUSION: The 3ST is a novel, reliable and safe alternative to the stand alone RFA-assisted technique. It is a faster procedure, and requires less blood units transfusion.

BACKGROUND: Total pancreatectomy and islet autotransplantation (TP/IAT) is a treatment option in a subset of patients with chronic pancreatitis. A systematic review of the literature was performed to evaluate the outcome of this procedure, with an attempt to ascertain when it is indicated. METHODS: MEDLINE (1950 to present), Embase (1980 to present) and the Cochrane Library were searched to identify studies of outcomes in patients undergoing TP/IAT. Cohort studies that reported the outcomes following the procedure were included. The MOOSE guidelines were used as a basis for this review. RESULTS: Five studies met the inclusion criteria. The techniques reported for pancreatectomy and islet cell isolation varied between studies. TP/IAT was successful in reducing pain in patients with chronic pancreatitis. Comparing morphine requirements before and after the procedure, two studies recorded significant reductions. Concurrent IAT reduced the insulin requirement after TP; the rate of insulin independence ranged from 46 per cent of patients at 5 years' mean follow-up to 10 per cent at 8 years. The impact on quality of life was poorly reported. The studies reviewed did not provide evidence for optimal timing of TP/IAT in relation to the evolution of chronic pancreatitis. CONCLUSION: This systematic review showed that TP/IAT had favourable outcomes with regard to pain reduction. Concurrent IAT enabled a significant proportion of patients to remain independent of insulin supplementation.

BACKGROUND: Serous adenomas represent 1-2% of pancreatic neoplasms and typically are asymptomatic not requiring any treatment and simple observation is the option of choice. Although, they carry a realistic risk of malignancy despite the general view that they never become malignant. We report a case, which, according to our best knowledge is the 27th case reported in the literature. METHODS: We reviewed the literature by performing a search in Pub Med and Medline. RESULTS: A 86-year old patient known to have a serous cystadenoma of the pancreas treated conservatively through a close clinical and radiological follow up which was unattended for 4 years ending up to our emergency department suffering an acute abdomen. Exploratory laparotomy revealed a perforated prepyloric ulcer which was treated accordingly. Patient died some weeks later due to severe medical co morbidities. CONCLUSION: Serous cystic neoplasms of the pancreas carry a realistic risk of malignancy despite the general view that they never become malignant. In our opinion the treatment strategy of serous cystic neoplasms of the pancreas should be aggressive even in cases of remote metastases since prognosis of the disease is satisfactory.

BACKGROUND: Appendiceal carcinoids (AC) are usually adequately treated by appendectomy. The European Neuroendocrine Tumours Society (ENETS) has recently reconsidered the previous pathologic criteria to identify patients at high risk of extra-appendiceal disease, who are thought to require right hemicolectomy (RHC). AIM: The aim of this retrospective, observational study was to evaluate previous and currently introduced criteria, in identifying patients with AC in whom RHC is justified. SUBJECTS AND METHODS: Twelve patients who underwent RHC for AC were retrospectively identified. Demographic and follow-up data were collected and appendectomy specimens were reviewed for the presence of indications leading to RHC defined as: tumor diameter ≥2 cm, tumor location at the base, mesoappendiceal extension, mitotic index Ki-67≥2%. RHC specimens were examined to identify evidence of extra-appendiceal disease, remaining and/or metastatic disease. RESULTS: Four patients fulfilled two criteria and 8 one criterion for RHC. Two patients had tumors ≥2.0 cm, 5 located at the base, 8 invading the mesoappendix and periappendiceal fat; Ki-67 PI was 1% in all cases measured except one, in which it was 3%. Post-RHC, 3 patients (25%) had extra-appendiceal disease (no residual disease was identified in surgical margins); 1 had tumor at the colon specimen and 2 had lymph node metastasis. All 3 patients fulfilled only one pathologic criterion; 1 had tumor mesoappendiceal extension and 2 tumor location at the base of the appendix. CONCLUSIONS: Applying previous and currently introduced pathologic criteria, 25% of high-risk patients with AC had identifiable extra-appendiceal disease following RHC that might be not detected following the recently introduced ENETS criteria.

OBJECTIVE: The isolated use of Doppler-guided haemorrhoidal artery ligation (DGHAL) may fail for advanced haemorrhoids (HR; grades III and IV). Suture haemorrhoidopexy (SHP) and mucopexy by rectoanal repair (RAR) result in haemorrhoidal lifting and fixation. A prospective evaluation was performed to evaluate the results of DGHAL combined with adjunctive procedures. METHOD: The study included 147 patients with HR (male patients: 102; grade III: 95, grade IV: 52) presenting with bleeding (73%) and prolapse (62%). RESULTS: More ligations were required for grade IV than grade III HR (10.7 + 2.8 vs 8.6 + 2.2, P < 0.001). SHP (28 patients) and RAR (18 patients) at 1-4 positions were deemed necessary in 46 (31%) patients. Minimal (muco-)cutaneous excision (MMCE) was added in 23 patients. SHP/RAR was applied more frequently in grade IV HR (60%vs 16%, P < 0.001). In patients not having MMCE, SHP/RAR was added in 57% of grade IV cases (P < 0.001). Complications included residual prolapse (10; two second surgery), bleeding (15; two second DGHAL), thrombosis (four), fissure (three) and fistula (one). Analgesia was required not at all, up to 1-3 days, 4-7 days and >7 days by 30%, 31%, 16% and 14% of the patients, respectively. SHP/RAR was associated with greater discomfort (17%vs 6%, P < 0.001). No differences were found between SHP and RAR. At an average follow-up of 15 months, 96% of patients were asymptomatic and 95% were satisfied. CONCLUSIONS: DGHAL with the selective application of SHP/RAR is a safe and effective technique for advanced grade HR.
