RESUMEN
AIMS: To describe the incidence of postoperative cystoid macular oedema (CMO) after endothelial keratoplasty (EK) and to identify its contributory risk factors. METHODS: 2233 patients undergoing EK at Ospedali Privati Forlì 'Villa Igea', between January 2005 to October 2018 for Descemet stripping automated endothelial keratoplasty (DSAEK) and June 2014 to August 2018 for Descemet membrane endothelial keratoplasty (DMEK) with a minimum follow-up of 18 months were evaluated. Univariate and multivariate analyses were conducted to identify and quantify contributory risk factors. Receiver operating characteristic (ROC) curve analysis were performed to determine ideal cut-off points of continuous variables. RESULTS: CMO was identified in 2.82% (n=63) of the cases. CMO occurred in 2.36% of DSAEK eyes and in 5.56% of DMEK eyes (p=0.001). Average onset of CMO was 4.27±6.63 months (range: 1-34 months) postoperatively. Compared with those who did not develop CMO, a higher proportion of patients in the CMO group had diabetes (24.2% vs 9.8%, p<0.001) (OR=3.16, 95% CI: 1.72 to 5.81, p<0.001), a higher proportion of patients who underwent DMEK rather than DSAEK (28.6% vs 14.1%, p=0.001) (OR=2.42, 95% CI: 1.35 to 4.33, p=0.003) and were older (70.5±10.0 vs 67.1±14.3 years, p=0.01). Using the cut-off of 67 years as identified by ROC curve analysis, subjects aged >67 years (OR=2.35, 95% CI: 1.30 to 4.26, p=0.005) were more likely to develop CMO. There were no other significant differences between the groups. CONCLUSIONS: Older age (>67 years), diabetes mellitus and DMEK have been identified as independent risk factors for postoperative CMO following EK. Close observation is necessary during the first postoperative year after EK, particularly in patients with risk factors.

ASBO is a common cause of emergency surgery and the use of laparoscopy for the treatment of these patients is still under debate and conflicting results have been published, in particular regarding the high risk of iatrogenic bowel injury. In fact, although over the last few years there has been an increasing enthusiasm in the surgical community about the advantages and potential better outcomes of laparoscopic management of adhesive small bowel obstruction (ASBO), recently published studies have introduced a significant word of caution. From 2011 in our centre, we have started to systematically approach ASBO in carefully selected patients with a step-by-step standardized laparoscopic procedure, developed and performed by a single operator experienced in emergency laparoscopy, collecting data in a prospective database. Inclusion criteria were: stable patients (without diffuse peritonitis and/or septic shock with suspicion of bowel perforation), CT scan findings consistent with a clear transition point and therefore suspected to have a single obstructing adhesive band. Patients with diffuse SB distension in the absence of a well-defined transition point and suspected to have diffuse matted adhesions (based on their surgical history and radiological findings) should be initially managed conservatively, including gastrografin challenge. Up to date, 83 patients were enrolled in the study. The rate of iatrogenic full-thickness bowel injury was 4/83 (4.8%); two of these cases were managed with simple repair and the other two required bowel resection and anastomosis. Conversion to open was performed in 3/4 of these cases, whereas in one a repair of the full-thickness injury was completed laparoscopically. All the iatrogenic injuries were detected intraoperatively and none of the reoperations that occurred in this series were due to missed bowel injuries. At 30 days follow-up, none reported incisional hernias or SSI or death. With the described accurate selection of patients, the use of such standardized step-by-step technique and in the presence of dedicated operating surgeons with advanced emergency surgery laparoscopic expertise, such procedure can be safe and feasible with multiple advantages in terms of morbidity and LOS. A careful preoperative selection of those patients who might be best candidates for laparoscopic adhesiolysis is needed. The level of laparoscopic expertise can also be highly variable, and not having advanced surgical expertise in the specific subspecialty of emergency laparoscopy, ultimately resulting in performing standardized procedures with proper careful and safe step-by-step technique, is highly recommended.

BACKGROUND: The role of laparoscopy in the diagnosis and treatment of stable abdominal trauma patients is still a matter of serious debate and only incomplete data are available. MATERIALS AND METHODS: We performed a systematic review and meta-analysis of the literature between January 1990 and August 2016. RESULTS: Overall, 9817 laparoscopies were performed for abdominal trauma; only 26.2% of the cases were converted to a laparotomy. The incidence of therapeutic laparotomies showed a reduction from 69% to 47.5%, whereas the incidence of therapeutic laparoscopies increased from 7.2% to 22.7%.The overall perioperative mortality rate was significantly lower in the laparoscopy group [odds ratio (M-H, random); 95% confidence interval, 0.35 (0.26-0.48)]. The same group showed shorter length of hospital stay [odds ratio (M-H, random); 95% confidence interval, -3.48 (-8.91 to 1.96)]. CONCLUSIONS: This systematic review shows a significant decrease in the use of laparoscopy in trauma patients. Most likely the widespread use of imaging techniques allows a more accurate selection of patients for diagnostic laparoscopy. Infact, a reduction in incidence of nontherapeutic laparotomies is evident in these selected patients undergoing diagnostic laparoscopy. Moreover, the literature reported an increasing trend of therapeutic laparoscopy, demonstrating that it is safe and effective. The small number and poor quality of the studies identified, the retrospective observational nature of the studies (low level of evidence), the high risk of bias, and the high heterogeneity of some outcomes make the applicability of the results of this meta-analysis unclear.

BACKGROUND: The recurrence rate, related to the unpredictable behavior of gastrointestinal stromal tumors (GISTs), continues to be a major topic of investigation, since no actual risk evaluation scales have proven to be exceedingly effective in predicting prognosis. We therefore focus in this study on investigating the predictive variables of disease recurrence. METHODS: Between September 2004 and January 2011, 34 patients, 18 males and 16 females with a median age of 62 (range, 27-87) years, underwent operations for primary, localized and advanced GISTs. Immunohistochemical profile, KIT and the platelet-derived growth factor receptor-alpha (PDGFR-α) gene mutations, tumor size, tumor site, mitotic index, synchronous tumors, adjuvant therapy, symptoms and gender were considered and analyzed as predictive variables. The receiver operating characteristic (ROC) analysis was used to determine the optimal cut-off value for tumor dimension to predict recurrence. RESULTS: The median follow-up (FU) was 20 months (range, 6-86 months). A first-line adjuvant therapy was performed in nine patients. Disease relapse occurred in five cases. The tumor size and the mitotic index were the strongest predictive factors (P<0.001). The optimal maximum value for the tumor size was 7 cm [area under the curve (AUC) =0.955]. CONCLUSIONS: In light of the most recent evidence, a tumor size of 7 cm should be considered the threshold value for malignancy, and smaller GISTs with low mitotic counts as tumors with a low-grade risk.
RESUMEN
INTRODUCTION: Modern management of severe acute complicated diverticulitis continues to evolve towards more conservative and minimally invasive strategies. Although open sigmoid colectomy with end colostomy remains the most commonly used procedure for the treatment of perforated diverticulitis with purulent/faeculent peritonitis, recent major advances challenged this traditional approach, including the increasing attitude towards primary anastomosis as an alternative to end colostomy and use of laparoscopic approach for urgent colectomy. TECHNIQUE: Provided an accurate patients selection, having the necessary haemodynamic stability, pneumoperitoneum is established with open Hasson technique and diagnostic laparoscopy is performed. If faeculent peritonitis (Hinchey IV perforated diverticulitis) is found, laparoscopy can be continued and a further three working ports are placed using bladeless trocars, as in traditional laparoscopic sigmoidectomy, with the addition of fourth trocar in left flank. The feacal matter is aspirated either with large-size suction devices or, in case of free solid stools, these can be removed with novel application of tight sealing endobags, which can be used for scooping the feacal content out and for its protected retrieval. After decontamination, a sigmoid colectomy is performed in the traditional laparoscopic fashion. The sigmoid is fully mobilised from the retroperitoneum, and mesocolon is divided up to the origin of left colic vessels. Whenever mesentery has extremely inflamed and thickened oedematous tissues, an endostapler with vascular load can be used to avoid vascular selective ligatures. Splenic flexure should be appropriately mobilised. The specimen is extracted through mini-Pfannenstiel incision with muscle splitting technique. Transanal colo-rectal anastomosis is fashioned. Air-leak test must be performed and drains placed where appropriate. RESULTS: The video shows operative technique for a single-stage, entirely laparoscopic, washout and sigmoid colectomy with primary colorectal anastomosis in a 35-year-old male patient with severe and diffuse free faeculent diverticular peritonitis (Hinchey IV). The patient was managed post-operatively according to enhanced recovery protocol and discharged home after 9 days, following an uneventful recovery. CONCLUSIONS: This case documents the technical feasibility of a minimally invasive single-stage procedure in a patient with Hinchey IV perforated diverticulitis with diffuse feacal peritonitis. The laparoscopic approach facilitated an effective decontamination of the peritoneal cavity, with a combination of large suction devices and aid of protected retrieval by closed endobags for effectively and completely laparoscopic removal of the solid feacal matter, offering clear advantages and excellent results even in such challenging cases. With necessary expertise, the sigmoid resection can be thereafter safely and entirely performed laparoscopically, the specimen extracted through mini-Pfannenstiel incision, and a laparoscopic intracorporeal transanal circular primary anastomosis performed.

BACKGROUND: Entero-atmospheric fistula (EAF) is an enteric fistula occurring in the setting of an open abdomen, thus creating a communication between the GI tract and the external atmosphere. Management and nursing of patients suffering EAF carries several challenges, and prevention of EAF should be the first and best treatment option. PURPOSE: Here, we present a novel modified classification of EAF and review the current state of the art in its prevention and management including nutritional issues and feeding strategies. We also provide an overview on surgical management principles, highlighting several surgical techniques for dealing with EAF that have been reported in the literature throughout the years. CONCLUSIONS: The treatment strategy for EAF should be multidisciplinary and multifaceted. Surgical treatment is most often multistep and should be tailored to the single patient, based on the type and characteristics of the EAF, following its correct identification and classification. The specific experience of surgeons and nursing staff in the management of EAF could be enhanced, applying distinct simulation-based ex vivo training models.

The greatest advantages of laparoscopy when compared to open surgery include the faster recovery times, shorter hospital stays, decreased postoperative pain, earlier return to work and resumption of normal daily activity as well as cosmetic benefits. Laparoscopy today is considered the gold standard of care in the treatment of cholecystitis and appendicitis worldwide. Laparoscopy has even been adopted in colorectal surgery with good results. The technological improvements in this surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its utilization in operations with fully intracorporeal anastomoses. Further progress in laparoscopy has included single-incision laparoscopic surgery and natural orifice trans-luminal endoscopic surgery. Nevertheless, laparoscopy for emergency surgery is still considered challenging and is usually not recommended due to the lack of adequate experience in this area. The technical difficulties of operating in the presence of diffuse peritonitis or large purulent collections and diffuse adhesions are also given as reasons. However, the potential advantages of laparoscopy, both in terms of diagnosis and therapy, are clear. Major advantages may be observed in cases with diffuse peritonitis secondary to perforated peptic ulcers, for example, where laparoscopy allows the confirmation of the diagnosis, the identification of the position of the ulcer and a laparoscopic repair with effective peritoneal washout. Laparoscopy has also revolutionized the approach to complicated diverticulitis even when intestinal perforation is present. Many other emergency conditions can be effectively managed laparoscopically, including trauma in select hemodynamically-stable patients. We have therefore reviewed the most recent scientific literature on advances in laparoscopy for acute care surgery and trauma in order to demonstrate the current indications and outcomes associated with a laparoscopic approach to the treatment of the most common emergency surgical conditions.

In the present study, we have described two possible approaches in the management of caustic injuries. Diagnostic emergency laparoscopy can be used for exploration in case of stable patients with Zargar's 3a gastric lesions and equivocal peritoneal signs. On the other hand, in case of patients with Zargar's 3b gastric lesions with perforation, diffuse peritonitis and hemodynamic instability, a new possible technique is described as an option to be used in such extensive caustic injuries: duodenal damage control with "4-tubes ostomy" for duodenal and jejunal wash-out of the caustic agent. The aim of this simple technique is to wash-out the caustic agent from the duodenum when the duodenum and Treitz are not yet gangrenous/perforated, as well as to avoid duodenal primary closure and jejuno-jejunal anastomosis over damaged tissues.
