Surgery for frail and elderly patients has some peculiarities. These individuals often have co-morbidities [2], need to take one or more drugs at the time of surgery and may be temporarily or permanently unable to take care of themselves autonomously. The peri-operative period could hence be very demanding for these patients and their relatives. Every effort should be made to reduce operative time, perioperative complications and length of stay in the hospital. Surgical principles remain the same, but it is important to involve elderly patients and who is taking care of them in surgical decision making. Patients are to be evaluated in the light of their disease stage but also – more importantly –of their performance status [2]. Geriatric surgeons must aim to radicality, to cure the disease for which surgery is being undertaken. At the same time it is fundamental to bear in mind that patients’ nuisances and their will to trade on surgery (and its potential consequences) should always guide the surgeons dealing with the elderly population. Aiming to reduce complications and optimise treatment, a relevant contribution is given by recent technological advancements in surgery and pre-operative instrumental imaging [3]. It is now accepted that robotic and laparoscopic surgery [4-6] can allow for better structures visualization, reduce intraoperative blood loss, postoperative pain, and postoperative ileus, allowing earlier patients mobilization in colorectal surgery. Advantages are even greater following the enhanced recovery after surgery (ERAS) pattern [7,8]. However, to fully benefit from a mini-invasive approach with earlier return to everyday activities, laparoscopic surgery and ERAS in the elderly must be used by experienced laparoscopic surgeons and in Units in which the ERAS protocol is being performed routinely. Vessel sealing devices are nowadays widely adopted also in the elderly. Bipolar radiofrequency-activated and ultrasound instruments are very useful in these patients, both in laparoscopic and in open surgery, allowing for minimized blood loss, precise tissues dissection and reduced transmission to surrounding structures [9,10]. Differently from conventional diathermy devices, these scalpels can also be safely adopted in patients with permanent pacemakers without provoking EKG disturbances [11]. There are specific diseases in which their use can offer advantages, such as thyroid surgery [9,12]. Elderly patients more often present with large goitres with compression and dislocation of adjacent structures which need to be identified and spared. Anaplastic carcinoma is a feature of older patients: it is highly invasive and easily bleeding, hence tissue sealing devices as well as instrumentation to identify nervous structures [13] can be extremely useful. Proctologic diseases are another field of application of energy technologies. When dealing with elderly patients suffering from proctologic disturbances, the perineal approach is to be preferred. Radiofrequency allows for haemorrhoidectomy being performed also in ambulatory settings, under local anesthesia, eliminating the need of hospitalizations [10]. It is effective in reducing postoperative pain (and need for analgesic drugs intake) and bleeding [10,14]. Trans-anal stapled procedures, namely procedure for prolapsing haemorrhoids (PPH) or stapled haemorrhoidopexy (SH) and stapled trans-anal rectal resection (STARR), have gained wide popularity recently for the treatment of III-degree piles without external component and obstructed defecation syndrome [15]. These techniques are reported to result in lower postoperative pain [15,16]. However, this observation should be counterbalanced with the higher rate of recurrences in the long-term follow-up and with several serious complications (even life-threatening ones) which have been associated with the procedures [15-17]. Careful patient selection is necessary, not to overlook potential underlying diseases [15,17,18]. We recommend conventional treatments, implemented by a prudent use of the above described technologies – avoiding blind trans-anal stapling. Ulcers, wounds which do not heal spontaneously, are often observed in elderly population. Regardless of the etiopathogenesis, a correct wound bed preparation for covering graft is paramount. High pressure fluid jet delivered by a hydrosurgery system offers better wound debridement than conventional methods without additional complications, and its use should therefore be encouraged in the elderly [19,20]. Negative pressure wound therapy (NPWT) has an established role in fixing dermal substitutes to acute as well as chronic wounds [21]. The fields of application of NPWT go far beyond: it is particularly useful in the eventuality of abdominal and perineal wound dehiscence, and in patients with entero-cutaneous fistulas. It is also suitable in wound breakdown in patients with a prosthetic mesh, allowing for mesh preservation and avoiding infections [22]. Side-effects include hemorrhage, protein and electrolytes loss and presumed reduced blood flow on the wall of bowel loops which are directly exposed to NPWT [23]. However, recent advances highlighted its safety in experienced hands. Newer devices are also less expensive, easier to manage and suitable for home-delivered treatment. Elderly patients are also often suffering from groin hernia. Studies [24,25] showed the usefulness of fibrin glue mesh fixing in reducing the blood loss, making it particularly suitable for patients with coagulation disorders [26]. Moreover, its beneficial effects are much more pronounced when newer large-pored light-weight meshes are used, achieving lower postoperative pain and less seroma formation [25]. Finally, palliation is another reason to advocate treatment of elderly patients. They may present with recurrent or advanced cancer lesions or may be unsuitable for extended procedures.
