RESUMO

BACKGROUND: To date, no standardized protocols nor a quantitative assessment of the near-infrared fluorescence angiography with indocyanine green (NIR-ICG) are available. The aim of this study was to evaluate the timing of fluorescence as a reproducible parameter and its efficacy in predicting anastomotic leakage (AL) in colorectal surgery. METHODS: A consecutive cohort of 108 patients undergoing minimally invasive elective procedures for colorectal cancer was prospectively enrolled. The difference between macro and microperfusion (ΔT) was obtained by calculating the timing of fluorescence at the level of iliac artery division and colonic wall, respectively. RESULTS: Subjects with a ΔT ≥ 15.5± 0.5 s had a higher tendency to develop an AL (p < 0.01). The ΔT/heart rate interaction was found to predict AL with an odds ratio of 1.02 (p < 0.01); a cut-off threshold of 832 was identified (sensitivity 0.86, specificity 0.77). Perfusion parameters were also associated with a faster bowel motility resumption and a reduced length of hospital stay. CONCLUSIONS: The analysis of the timing of fluorescence provides a quantitative, easy evaluation of tissue perfusion. A ΔT/HR interaction ≥832 may be used as a real-time parameter to guide surgical decision making in colorectal surgery.

RESUMO

Acinar cystic transformation (ACT), also known as 'acinar cell cystadenoma', is an uncommon cystic neoplasm of pancreas with unknown malignant potential. This case regards a woman with symptomatic pancreatic head ACT, revealed with pathological exam of specimen after pancreaticoduodenectomy. A 57-years-old patient presented mild hyperbilirubinemia and recurrent cholangitis; she underwent to ERCP, EUS and MRI, and these exams revealed a large cyst of the pancreatic head that caused biliary compression. The discussion of the case by the multidisciplinary group indicated surgical resection. Pancreatic ACT is so rare, and its preoperative diagnosis is difficult. The symptoms of the patients and the features of the cyst are the criteria to choose a surgical resection.

RESUMO

Solid pseudopapillary tumour is a rare low-grade malignant potential carcinoma of the pancreas that typically occurs in females in their third decade. It most commonly occurs in the tail of the pancreas, although any site can be affected. Surgical resection is the standard treatment and offers an excellent prognosis. We report a case of a 17-year-old female with an acute onset abdominal pain and a radiological diagnosis of a cystic lesion in the distal pancreas. A robotic-assisted distal pancreatectomy with splenectomy was performed. Robotic-assisted surgery is an emerging technique for the treatment of pancreatic neoplasms. This approach can be considered for younger patients, thanks to the potential advantages of the robotic Da Vinci Xi System.

RESUMO

INTRODUCTION AND AIM OF THE STUDY: Dunbar syndrome is a rare disorder due to the external compression of the celiac trunk by the median arcuate ligament. The symptoms include abdominal pain, nausea and vomiting with a significative reduction in patients' quality of life. Laparoscopy has proven to be a safe procedure. The aim of this study is to present a case of Dunbar syndrome undergoing laparoscopic surgery. CASE PRESENTATION: A 40-year-old male patient presented at Emergency Room with upper abdominal pain and dyspepsia, related to food intake. A selective arteriography of the celiac trunk revealed stenosis due to compression of the celiac artery. CLINICAL DISCUSSION: Laparoscopic decompression of the celiac trunk by the median arcuate ligament was performed. Postoperative course was uneventful and the patient was discharged on the 5th postoperative day. CONCLUSION: Minimally invasive surgical division of the arcuate ligament is feasible and safe and it can restore patients' quality of life.

RESUMO

The surgical treatment for patients with generalized peritonitis complicating sigmoid diverticulitis is currently debated; particularly in case of diffuse purulent contamination (Hinchey 3). Laparoscopic lavage and drainage (LLD) has been proposed by some authors as a safe and effective alternative to single- or multi-stage resective surgery. However, among all the different studies on LLD, there is no uniformity in terms of surgical technique adopted and data show significant differences in postoperative outcomes. Aim of this review was to analyze the differences and similarities among the authors in terms of application, surgical technique and outcomes of LLD in Hinchey 3 patients. A bibliographical research was performed by referring to PubMed and Cochrane. "Purulent peritonitis", "Hinchey 3 diverticulitis", "acute diverticulitis", "colonic perforation" and "complicated diverticulitis" were used as key words. Twenty-eight papers were selected, excluding meta-analysis, reviews and case reports with a very small number of patients. The aim of this review was to establish how LLD should be done, suggesting important technical tricks. We found agreement in terms of indications, preoperative management, ports' positioning, antibiotics, enteral feeding and drain management. On the contrast, different statements regarding indications, adhesiolysis and management of colonic hole and failure of laparoscopic lavage are reported. A widespread diffusion of LLD and standardization of its technique are impossible because of data heterogeneity and selection bias in the limited RCTs. It is necessary to wait for long terms results from randomized clinical trials (RCTs) in progress to establish the efficacy and safety of this technique. More importantly, an increased number of highly skilled and dedicated colorectal laparoscopic surgeons are required to standardized the procedure.

RESUMO

BACKGROUND: Recently, minimally invasive treatment of complicated sigmoid diverticulitis is becoming a valid alternative to standard procedures. Robotic approach may be useful to allow more precise dissection in arduous pelvic dissection as in complicated diverticulitis. The aim of this study is to investigate effectiveness, potential benefits and short-term outcomes of robotic-assisted laparoscopic surgical resection, compared with fully laparoscopic resection in complicated diverticulitis. METHODS: Between January 2009 and December 2017, 156 consecutive patients with history of complicated diverticular disease were referred to our Department of General, Mininvasive and Robotic Surgery. All patients underwent elective colonic resections performed by the same colorectal surgeon and followed a perioperative ERAS program. Demographic and clinical features, surgical data, postoperative data, 30-day morbidity and mortality, VAS for surgeon's compliance were evaluated. RESULTS: One hundred and fifty-six consecutive patients underwent elective colonic resection: 92 fully laparoscopic (FL) colorectal resections and 64 procedures with robotic hybrid approach (RHA). Conversion rate was none in the RHA group versus 6.5% in the FL group, because of poor vision due to bowel distension, inflammatory pseudotumor and peritoneal adhesions. No 30-day mortality was observed. Mean operative time was 167.5 ± 54.4 min (80-420) in the FL group and 172.5 ± 55.64 min (110-325) in the RHA group (p 0.079), mean intraoperative blood loss was 144.6 ± 40.6 ml (40-200) with the FL technique and 138.4 ± 28.3 ml (20-185) with the RHA (p 0.295). Mean hospital stay for FL was 5 ± 4.1 days (range 3-45) and 5 ± 2.7 days (range 3-20) for RHA (p 0.974). Overall postoperative morbidity rate was 21.6% in the FL group and 12.3% in the RHA (p 0.067). Major postoperative morbidity (Clavien-Dindo 3 and 4) represented 13% and 4.6%, respectively (p 0.091). VAS for surgeon's compliance revealed a better performance in the robotic arm (p 0.059). CONCLUSIONS: This preliminary study highlights the potential benefits of robotic-assisted laparoscopy in colorectal resections for complicated diverticular disease in terms of surgical efficacy, postoperative morbidity and better surgeon's compliance.

RESUMO

BACKGROUND: Hartmann's procedure (HP) followed by reversal restoration is the first choice for treatment of diffuse diverticular peritonitis. There is no unanimous consensus regarding the use of laparoscopy to treat the same condition. METHODS: Data from 60 patients with diverticular diffuse peritonitis who underwent urgent HP followed by laparoscopic reversal were retrospectively analyzed. Patients were divided into 2 groups according to the open or laparoscopic HP (OHP, 24 patients; LHP, 36 patients). Outcomes were measured in terms of functional recovery, morbidity, mortality, and length of hospital stay. RESULTS: HPs showed no differences among the groups in terms of operative time, blood loss, and length of intensive care unit stay. Overall morbidity was significantly lower in LHP than in OHP, corresponding to 33.3% and 66.7% respectively ( P = .018). The incidence of both surgical and medical complications was higher in OHP than in LHP (41.7% vs 22.2% [ P = .044] and 45.8% vs 24.3% [ P = .023], respectively). Mortality was 16.6% for each group. LHP showed a faster return to bowel movements and a shorter hospital stay than OHP. The secondary intestinal reversal was possible in 92% of cases, successfully completed laparoscopically in 91.3%. No patients of LHP group required a conversion to open intestinal reversal. CONCLUSION: LHP for treatment of diverticular diffuse peritonitis showed significantly lower morbidity, faster recovery, shorter hospital stay, and higher rates of successful laparoscopic reversal when compared with OHP.

RESUMO

Nowadays laparoscopic approach is accepted as a valid alternative to open surgery for the treatment of colorectal cancer. Several studies consider this approach to be safe and feasible also in obese patients, even if dissection in these patients may require a longer operative time and involve higher blood loss. To facilitate laparoscopic approach, more difficult in these patients, several energy sources for laparoscopic dissection and sealing, has been adopted recently. The aim of this study is to investigate the possible intraoperative advantages of radiofrequency energy in terms of blood loss and operative time in obese patients undergoing laparoscopic resection for cancer. All patients who underwent laparoscopic surgery for colorectal cancer from January 2010 to December 2015 were registered in a prospective database. Patients with a body mass index BMI (kg/m2) ≥30 were defined as obese, and patients with a BMI (kg/m2) <30 were defined as non-obese. All 136 obese patients observed were divided retrospectively into 2 groups according to the devices used for dissection: 83 patients (Historical group: B) on whom dissection and coagulation were performed using other energy sources (monopolar electrocautery scissors, bipolar electrical energy, ultrasonic coagulating shears) and 53 patients who were treated with electrothermal bipolar vessel sealing (Caiman group: A). In group A, the Laparoscopic Caiman 5 (Aesculap AG, Tuttlingen, Germany) was the only instrument employed in the whole procedure. The study examined only three types of operation: right colectomy (RC), left colectomy (LC), and anterior resection (AR). Preoperative data were similar for RC, LC, and AR in both groups (A and B). The mean operative time was statistically shorter in the Caiman group than in the Historical group [104 vs 124 min (p 0.004), 116 vs 140 min (p 0.004), and 125 vs 151 min (p 0.003) for RC, LC, and AR between group A and B, respectively]. Also intraoperative blood loss results significantly lower in the Caiman group than in the historical one [52 ml vs 93 for RC (p 0.003); 65 vs 120 ml for LC (p 0.001); 93 vs 145 ml for AR (p 0.002) between group A and B, respectively]. No intraoperative complications were recorded in either group. The mean conversion rate was 4.4% (6 patients). There were no statistical differences in intensive care unit (ICU) stay, functional outcomes, mean hospital stay and overall morbidity rate between the two groups. There was no mortality in either group. The use of the Caiman EBVS instrument shows significant advantages with respect to a small number of intraoperative parameters. We can conclude that use of this radiofrequency device, in the laparoscopic approach, offers advantages in terms of lower intraoperative blood loss and shorter operative time in obese patients with colorectal cancer.

RESUMO

BACKGROUND: Deep pelvic endometriosis is a complex disorder that affects 6% to 12% of all women in childbearing age. The incidence of bowel endometriosis ranges between 5.3% and 12%, with rectum and sigma being the most frequently involved tracts, accounting for about 80% of cases. It has been reported that segmental colorectal resection is the best surgical option in terms of recurrence rate and improvement of symptoms. The aim of this study is to analyze indications, feasibility, limits, and short-term results of robotic (Da Vinci Surgical System)-assisted laparoscopic rectal sigmoidectomy for the treatment of deep pelvic endometriosis. PATIENTS AND METHODS: Between January 2006 and December 2010, 19 women with bowel endometriosis underwent colorectal resection through the robotic-assisted laparoscopic approach. Intraoperative and postoperative data were collected. All procedures were performed in a single center and short-term complications were evaluated. RESULTS: Nineteen robotic-assisted laparoscopic colorectal resections for infiltrating endometriosis were achieved. Additional procedures were performed in 7 patients (37%). No laparotomic conversion was performed. No intraoperative complications were observed. The mean operative time was 370 minutes (range = 250-720 minutes), and the estimated blood loss was 250 mL (range = 50-350 mL). The overall complication rate was 10% (2 rectovaginal fistulae). CONCLUSIONS: Deep pelvic endometriosis is a benign condition but may have substantial impact on quality of life due to severe pelvic symptoms. We believe that robotic-assisted laparoscopic colorectal resection is a feasible and relatively safe procedure in the context of close collaboration between gynecologists and surgeons for treatment of deep pelvic endometriosis with intestinal involvement, with low rates of complications and significant improvement of intestinal symptoms.
