Clinico-pathological Features of Colon Cancer Patients Undergoing Emergency Surgery: A Comparison Between Elderly and Non-elderly Patients

BACKGROUND

Colorectal cancer (CRC) is one of the most common cancers in patients older than 65 years. Emergency presentation represents about 30% of cases, with increased morbidity and mortality rates. The aim of this study is to compare the perioperative outcome between elderly and non-elderly patients undergoing emergency surgery.

METHOD

We retrospectively analysed CRC patients that underwent emergency surgery at the Departments of Surgery of the Sapienza University Sant'Andrea Hospital in Rome, and at San Donato Hospital in Arezzo, between June 2012 and June 2017. Patients were divided into two groups: non-elderly (< 65 years) and elderly (≥ 65 years). Variables analysed were sex, onset symptoms, associated disease, ASA score, tumor site and TNM stage, surgical procedures and approach, and morbidity and mortality.

RESULTS

Of a total of 123 patients, 29 patients were non-elderly and 94 patients were elderly. No significant differences were observed in sex, onset symptoms and tumor site between the two groups. Comorbidities were significantly higher in elderly patients (73.4% vs 41.4%, p<0.001). No significant differences were observed between the two groups in surgical approach and the rate of one-stage procedures. Elderly patients were more frequently treated by Hartmann's procedure compared to non-elderly patients (20.2% vs 6.9%). Left colorectal resection with protective ileostomy was most frequent in the non-elderly group (27.6% vs 11.7%). No significant differences were found in the pT and pN categories of the TNM system between the two groups. However, a higher number of T3 in non-elderly patients was observed. A consistent number of non-oncologically adequate resections were observed in the elderly (21.3% vs 3.5%; p<0.03). The morbidity rate was significantly higher in the elderly group (31.9 % vs 3.4%, p<0.001). No significant difference was found in the mortality rate between the two groups, being 13.8% in the elderly and 6.9% in the non-elderly.

CONCLUSIONS

Emergency colorectal surgery for cancer still presents significant morbidity and mortality rates, especially in elderly patients. More aggressive tumors and advanced stages were more frequent in the non-elderly group and as a matter it should be taken into account when treating such patients in the emergency setting in order to perform a radical procedure as much as possible.

Management of Complications of First Instance of Hepatic Trauma in a Liver Surgery Unit: Portal Vein Ligation as a Conservative Therapeutic Strategy

BACKGROUND

According to the National Trauma Data Bank, the liver, after the spleen, is the first most injured organ in closed abdominal trauma.

METHODS

From June 2010 to December 2015 we observed in our department of Hepato-biliary Surgery and Liver Transplant Unit of the A.O.R.N. A. Cardarelli of Naples 40 patients affected by hepatic trauma. In our retrospective study, we review our experience and propose portal vein ligation (PVL) as a first - line strategy for damage control surgery (DCS) in liver trauma.

RESULTS

26/40 patients (65%) which received gauze-packing represented our study group. In 10 cases out of 26 patients (38,4%) the abdominal packing was enough to control the damage. In 7 cases (18,4%) we performed a liver resection. In 7 cases, after de-packing, we adopted PVL to achieve DCS. Trans Arterial Embolization was chosen in 6 patients. 2 of them were discharged 14 days later without performing any other procedure.In 3 cases we had to perform a right epatectomy in second instance. Two hepatectomies were due to hemoperitoneum, and the other for coleperitoneum. Two patients were treated in first instance by only doing hemostasis on the bleeding site. We observed 6 patients in first instance. Five of them underwent surgery with hepatic resection and surgical hemostasis of the bleeding site. The other one underwent to conservative management. In summary we performed 15 hepatic resections, 8 of them were right hepatectomies, 1 left hepatectomy, 2 trisegmentectomies V-VI-VII. So in second instance we operated on 10 patients out of 34 (30%).

CONCLUSIONS

The improved knowledge of clinical physio-pathology and the improvement of diagnostic and instrumental techniques had a great impact on the prognosis of liver trauma. We think that a rigid diagnostic protocol should be applied as this allows timely pathological finding, and consists of three successive but perfectly integrated steps: 1) patient reception, in close collaboration with the resuscitator; 2) accurate but quick diagnostic framing 3) therapeutic decisional making. Selective portal vein ligation is a well-tolerated and safe manoeuvre, which could be effective, even if not definitive, in treating these subjects. That is why we believe that it can be a choice to keep in mind especially in post-depacking bleeding.

Theory of Relativity for Posterosuperior Segments of the Liver

BACKGROUND

The accessibility to posterosuperior segments of the liver has traditionally constituted a restrain to adopt the laparoscopic approach in this setting. To overcome this challenge, multiple approaches have been reported in literature. Total transabdominal approach has been previously described for this purpose, even though the rationale to standardly adopt it and a technical depiction of how to achieve an optimal mobilization has never been specifically addressed.

METHODS

Total transabdominal purely laparoscopic approach to posterosuperior segments of the liver is presented, with detailed emphasis to the rotational motions targeted in laparoscopy. A literature review is presented to summarize all other possible accesses to posterosuperior area of the liver. The institutional series for the laparoscopic approach to Sg 7, Sg 6+7, and Sg8 is retrospectively described.

RESULTS

Three rotational motions of the liver are specifically addressed in a video presentation and described for the laparoscopic total-transabdominal approach; the local institutional series using this approach is presented. Other miscellaneous approaches identified from literature encompassing variations in operative position, transabdominal, transthoracic, and combined approaches are described.

CONCLUSIONS

Complete mobilization of the ligaments of the liver leads to a rotation of the transection line in front of the operator's view, allowing to achieve a safe total trans-abdominal laparoscopic approach to the posterosuperior ligaments of the liver, without compromising the vascular inflow control, the possibility to convert to open approach, nor requiring potentially harmful decubitus.

Robot-assisted liver surgery in a general surgery unit with a "Referral Centre Hub&Spoke Learning Program". Early outcomes after our first 70 consecutive patients

BACKGROUND

The aim of this study was to evaluate safety, feasibility and short-term outcomes of our first 70 consecutive patients treated by robotic-assisted liver resection after a reversal proctoring between a high HPB volume centre and our well-trained center in minimally invasive General Surgery. Six surgeons were involved in this Hub&Spoke learning program.

METHODS

From September 2012 to December 2016, 70 patients underwent robotic-assisted liver resections (RALR). We treated 18 patients affected by colorectal and gastric cancer with synchronous liver lesions suspected for metastases in a one-stage robotic-assisted procedure. For the first 20 procedures we had a tutor in the operatory room, who was present also in the next most difficult procedures.

RESULTS

The 30- and 90-day mortality rate was zero with an overall morbidity rate of 10.1%. Associated surgical procedures were performed in about 65,7% of patients. The observed conversion rate was 10%. The results of the first 20 cases were similar to the next 50 showing a shortned learning curve.

CONCLUSIONS

Minimally invasive robot-assisted liver resection is a safe technique; it allows overcoming many limits of conventional laparoscopy. This innovative, time-enduring Hub&Spoke may allow patients to undergo a proper standard of care also for complex surgical procedures, without the need of reaching referral centres.

Laparoscopic liver resection: the current status and the future

Dramatic progresses had been made in the operation in the past 26 years. Procedure was extended to major liver resection, isolated resection of caudate lobe, living donor liver resection and associating liver partition with portal vein ligation for staged hepatectomy (ALPPS). Laparoscopic liver resection became a new group of HPB surgery and the international laparoscopic liver society was established in Paris followed by the first international congress of the society held in Paris in July 2017. This biannual congress would be top convention for surgeons specialized in laparoscopic liver surgery. The advantage of laparoscopic liver resection had been recognized by patients and surgeons and is gradually replacing conventional open liver resection in some experienced institutes worldwide. Most procedures, such as laparoscopic local resection and left lateral segmentectomy, could be routinely performed, but some procedures including laparoscopic hemihepatectomy still need to be further evaluated. For now, the establishment of a training system for laparoscopic liver surgeons became the most important issue for the popularization of laparoscopic liver resection.

Pure laparoscopic right hepatectomy in a patient with situs inversus totalis: A case report

RATIONALE

Hepatectomy in a patient with situs inversus totalis (SIT) is technically challenging, and pure laparoscopic major hepatectomy has not been previously described.

PATIENT CONCERNS

A 70-year-old male with SIT was referred to our hospital for investigation and treatment of a liver mass in segment 5/6.

DIAGNOSIS

Computed tomography (CT) and magnetic resonance imaging (MRI) showed features of chronic liver disease and a 5-cm sized mass with a bulging contour at segment 5/6.

INTERVENTIONS

Pure laparoscopic right hepatectomy was performed.

OUTCOMES

There was no intraoperative complication and the procedure was completed without a transfusion. The patient recovered well and was discharged on postoperative day 8.

LESSONS

Considering the position of the port sites and the assistant, and the operator's hand for the working port, a pure laparoscopic right hepatectomy can be a feasible procedure, even in a patient with SIT.
