The role of telemedicine in the postoperative home monitoring after robotic colo-rectal cancer surgery: a preliminary single center experience

The telemedicine studies, takes care and prevents diseases at distance basing on the interaction among physicians and patients remotely. Few data are available on its application to early postoperative after surgery. The endpoints of our preliminary experience were the detection, as primary, of feasibility and safety of home telemonitoring after robotic colo-rectal resection and, as secondary, perception and satisfaction of the patients. From December 2019 to March 2020, at the Division of Robotic Surgery of San Giovanni Hospital of Rome, 20 of 29 colorectal cancer patients, submitted to Robotic resection, were prospectively included in a program of postoperative home telemonitoring. Telemonitoring was considered feasible if at least 75% of data were available and safe if morbidity ≤ II by Clavien-Dindo classification. Perception and patients' satisfaction were evaluated through a dedicated questionnaire. Out of 20 patients, the median age was 68 years, overall postoperative morbidity was 30%, all events classified Clavien-Dindo Grade I or II. Only 2 patients were corresponded to surgical consult without readmission during home telemonitoring. Compliance of patients was > 80%, overall grade of satisfaction was very high: 4.2 as median (range 0-5). In this preliminary study, the procedures of postoperative home telemonitoring were feasible and safe and high rate of patients' satisfaction was observed. The telemedicine could enhance the role of robotic technique in decrease the hospital stay and improving postoperative recovery after surgery. Further structured prospective trial are needed to validate the routine application of telemedicine in healthcare.

Primary leiomyoma of the liver in an immunocompetent patient

Primary leiomyoma of the liver (PLL) is a rare benign tumor occurring in immunosuppressed people. From 1926 less than fifty cases are reported in the scientific literature and about half are in immunocompetent patients. Etiology of this kind of lesion is not yet well known. We report a case of primary hepatic leiomyoma in a 60-year-old immunocompetent woman. The patient presented with lipothymia with unexpected vomiting. She underwent an ultrasound (US), and a computed tomography (CT) scan that revealed the presence of a single, solid lesion about 9 cm located between the S5 and S8 segment of the liver. It showed a well-defined, heterogeneous hypodensity with internal and peripheral enhancement and various central hypoattenuating areas and no wash-out in the portal and the late phases. Because of her symptoms and the risk of malignancy, the patient underwent a surgical liver resection. Histological diagnosis was primary leiomyoma of the liver. The patient had an uneventful recovery and was discharged after 7 days. At 30 months follow-up there were no symptoms and no evidence of disease. Leiomyoma of the liver is a rare benign neoplasm of which clinical symptoms are nonspecific and the exact radiological diagnosis still remains a challenge for radiologists. Etiology is still unclear and usually PLL represents an incidental diagnosis. Surgery plays a primary role not only in the treatment algorithm, but also in the diagnostic workout.

Organ-saving surgery for rectal cancer after neoadjuvant chemoradiation: Analysis of failures and long-term results

BACKGROUND

To analyze long-term results and risk of relapse in the clinical TNM stages II and III, mid-low rectal cancer patients (RC pts), treated with transanal local excision (LE) after major response to neoadjuvant chemoradiation (n-CRT).

METHODS

Thirty-two out of 345 extraperitoneal cT3-4 or N+ RC pts (9.3%) underwent LE.

INCLUSION CRITERIA

extraperitoneal RC, adenocarcinoma, ECOG Performance Status ≤2. Pts with distant metastases were excluded.

RESULTS

All pts showed histologically clear margins of resection and 81.2% were restaged ypT0/mic/1. Nine out of 32 (28.1%) pts relapsed: 7 (21.8%) showed a local recurrence, of which 5 (15.6%) at the endorectal suture, 1 (3.1%) pelvic and 1 (3.1%) mesorectal. Two pts (6.2%) relapsed distantly. Among the pT0/1, 11.5% relapsed vs 100% of the pT2 and pT4 ones. The six pts relapsing locally or in the mesorectal fat underwent a salvage total mesorectal excision surgery. The old patient with pelvic recurrence relapsed after 108 months and underwent a re-irradiation; the two pts with distant metastases were treated with chemotherapy followed by radical surgery.

CONCLUSIONS

Presently combined approach seems a valid option in major responders, confirming its potential curative impact in the ypT0/mic/1 pts. A strict selection of pts is basic to obtain favourable results.

Tumor Regression Grade After Neoadjuvant Chemoradiation and Surgery for Low Rectal Cancer Evaluated by Multiple Correspondence Analysis: Ten Years as Minimum Follow-up

BACKGROUND

The role of Mandard's tumor regression grade (TRG) classification is still controversial in defining the prognostic role of patients who have undergone neoadjuvant chemoradiation (CRT) and total mesorectal excision. The present study evaluated multiple correspondence analysis (MCA) as a tool to better cluster variables, including TRG, for a homogeneous prognosis.

PATIENTS AND METHODS

A total of 174 patients with a minimum follow-up period of 10 years were stratified into 2 groups: group A (TRG 1-3) and group B (TRG 4-5) using Mandard's classification. Overall survival and disease-free survival were analyzed using univariate and multivariate analysis. Subsequently, MCA was used to analyze TRG plus the other prognostic variables.

RESULTS

The overall response to CRT was 55.7%, including 13.2% with a pathologic complete response. TRG group A correlated strictly with pN status (P = .0001) and had better overall and disease-free survival than group B (85.1% and 75.6% vs. 71.1% and 67.3%; P = .06 and P = .04, respectively). The TRG 3 subset (about one third of our series) showed prognostically heterogeneous behavior. In addition to multivariate analysis, MCA separated TRG 1 and TRG 2 versus TRG 4 and TRG 5 well and also allocated TRG 3 patients close to the unfavorable prognostic variables.

CONCLUSION

TRG classification should be used in all pathologic reports after neoadjuvant CRT and radical surgery to enrich the prognostic profile of patients with an intermediate risk of relapse and to identify patients eligible for more conservative treatment. Thus, MCA could provide added value.

Laparoscopic left liver resections: how far can we go?

INTRODUCTION

The aim of this study was to analyse the outcomes of laparoscopic anatomic hepatectomies of the left liver segments.

METHODS

This is a retrospective multicentre study including all patients operated on laparoscopically divided into unisegmentectomy of 2, 3 or 4 (Group 1), left lobectomy (or left lateral sectionectomy LLS) (Group 2), left hepatectomy (Group 3) and extended left hepatectomy (Group 4) between 2000 and 2016. These four groups were compared in terms of demographics, intraoperative data and postoperative outcomes.

RESULTS

Among the 190 selected patients, the groups 1, 2, 3, 4 included 25 (13.2%), 116 (61.0%), 27 (14.2%) and 22 (11.6%) patients, respectively. The cohorts were comparable except for the number of lesions (p = 0.001) and tumour diameter (p = 0.004). The operative time, blood loss and the use of vascular clamping were more frequent in the Groups 3 and 4 (p = 0.0001), as is the rate of conversion to laparotomy (p = 0.001). Total morbidity was 23.3%, and major complications were more frequent in Group 4 (p = 0.0001). The prevalence of hepatic complications (11.6%), intra-abdominal collections (7.4%) and respiratory complications (3.7%) was proportionally correlated to the hepatectomy extension (p = 0.0001).

CONCLUSION

All laparoscopic left liver resections seem safe and feasible even though extended hepatectomy is associated with a significant morbidity.

A literature review on surgery for cervical vagal schwannomas

Cervical vagal schwannoma is a benign, slow-growing mass, often asymptomatic, with a very low lifetime risk of malignant transformation in general population, but diagnosis is still a challenge. Surgical resection is the treatment of choice even if its close relationship with nerve fibres, from which it arises, threats vagal nerve preservation. We present a case report and a systematic review of literature. All studies on surgical resection of cervical vagal schwannoma have been reviewed. Papers matching the inclusion criteria (topic on surgical removal of cervical vagal schwannoma, English language, full text available) were selected. Fifty-three patients with vagal neck schwannoma submitted to surgery were identified among 22 studies selected. Female/male ratio was 1.5 and median age 44 years. Median diameter was 5 cm (range 2 to 10). Most schwannoma were asymptomatic (68.2%) and received an intracapsular excision (64.9%). Postoperative symptoms were reported in 22.6% of patients. Cervical vagal schwannoma is a benign pathology requiring surgical excision, but frequently postoperative complications can affect patients lifelong, so, surgical indications should be based carefully on the balance between risks and benefits.

Detection of phosphorylated insulin receptor in colorectal adenoma and adenocarcinoma: implications for prognosis and clinical outcome

Colorectal carcinoma remains among the most frequent causes of cancer death. Besides the well-known genetic predisposition, a key role in colorectal adenoma and adenocarcinoma etio-pathogenesis, mainly in sporadic cases, is played by definite risk factors, such as obesity, type 2 diabetes, insulin resistance, hyper-insulinemia, and insulin therapy. These epidemiological data motivated us to determine, by means of immunohistochemistry, the amount of activated (phosphorylated) insulin receptor in archival samples from 22 colorectal adenoma and 117 adenocarcinoma patients, with the objective to estimate the role of this factor in colorectal epithelium transformation and cancer progression. Statistical analysis of the results clearly showed that positive staining for phosphorylated insulin receptor was significantly more frequent in adenomas than adenocarcinomas (P < 0.0001) and, within the adenocarcinoma cohort, it was more frequent in low-grade tumors (P = 0.005). In adenomas, staining was exclusively cytoplasmic, while in adenocarcinomas it was cytoplasmic and/or nuclear (P < 0.0001). Interestingly, disease-free survival in colorectal adenocarcinoma patients pointed out a significantly better prognosis for those bearing a positive staining for phosphorylated insulin receptor (P = 0.02). From these data, we can argue that activated insulin receptor plays a fundamental role at the early stages of tumorigenesis, where late stages could be characterized by a shift toward more active oncogenic drivers. Determining the amount of phosphorylated insulin receptor could thus represent a novel prognostic/predictive tool in colorectal adenocarcinoma patients.

Prevalence of adenoma of gallbladder, ultrasonographic and histological assessment in a retrospective series of 450 cholecystectomy

BACKGROUND

Adenomyomas of the gallbladder are difficult to examine during standard ultrasound examination of the abdomen. They sometimes undergo malignant transformation and their optimal management still remains a problem. The authors have aimed to investigate the ultrasonographic and histopathological prevalence of gallbladder adenomyomas focusing on the diagnostic performance of ultrasound examination.

MATERIALS AND METHODS

A retrospective series of 450 consecutive patients who underwent cholecystectomy is reported. Data regarding characteristics of the patients, US and histology examination of the gallbladder were collected. Sensitivity, specificity, positive and negative predictive values of ultrasound scan were calculated with respect to histological examination of the gallbladder.

RESULTS

The study group consisted of 261 female and 189 male. Ultrasound scan detected adenomyomas in 22 patients, confirmed by histopathology in 13 and found to be not present in 9. Incidental adenomyomas were found in 16 patients of 428 who underwent cholecystectomy for gallstones. Prevalence was 4.9% and 6.4% for ultrasound scan and histopathology respectively. Ultrasound scan showed sensitivity of 43.3% (c.i.:25.4%-62.5%), specificity of 97.8% (c.i.:95.9%-99%) with a positive predictive value of 59% (c.i.:36.3%-79.2%) and with a negative predictive value of 96.2% (c.i.:93.7%- 97.6%). On histopathology, adenomyomas localized in the fundus were predominant. Two female patients with adenomyomas of the fundus (diameter 5 mm) and single stone showed intestinal metaplasia with high-grade dysplasia.

CONCLUSIONS

The diagnosis of gallbladder adenomyomas by ultrasound scan still remains a problem because of its low sensitivity, which is mainly due to the association with gallstones. Histopathological findings in the perilesional mucosa confirm the hypothesis of a metaplasia-dysplasia-carcinoma sequence already shown in the colon-rectum. At present, the selection of patients requiring cholecystectomy is still controversial.

Drain after elective laparoscopic cholecystectomy. A randomized multicentre controlled trial

BACKGROUND

Routine drainage after laparoscopic cholecystectomy is still debatable. The present study was designed to assess the role of drains in laparoscopic cholecystectomy performed for nonacutely inflamed gallbladder.

METHODS

After laparoscopic gallbladder removal, 53 patients were randomized to have a suction drain positioned in the subhepatic space and 53 patients to have a sham drain. The primary outcome measure was the presence of subhepatic fluid collection at abdominal ultrasonography, performed 24 h after surgery. Secondary outcome measures were postoperative abdominal and shoulder tip pain, use of analgesics, nausea, vomiting, and morbidity.

RESULTS

Subhepatic fluid collection was not found in 45 patients (84.9 %) in group A and in 46 patients (86.8 %) in group B (difference 1.9 (95 % confidence interval -11.37 to 15.17; P = 0.998). No significant difference in visual analogue scale scores with respect to abdominal and shoulder pain, use of parenteral ketorolac, nausea, and vomiting were found in either group. Two (1.9 %) significant hemorrhagic events occurred postoperatively. Wound infection was observed in three patients (5.7 %) in group A and two patients (3.8 %) in group B (difference 1.9 (95 % CI -6.19 to 9.99; P = 0.997).

CONCLUSIONS

The present study was unable to prove that the drain was useful in elective, uncomplicated LC.

[Mesh infection in inguinal hernioplasty by Streptococcus dysgalactiae subspecies equisimilis. Case report and review of the literature]

INTRODUCTION

Mesh infection in inguinal herniography is usually caused by Staphilococcus aureus and Staphilcoccus epidermidis. Generally it obliges to prosthesis removal with hernia relapse and increase of social costs for the prolongation of hospitalization.

CASE REPORT

A 60-year-old woman, obese, undergone 4 months before to left inguinal prosthetic herniorrhaphy complicated by infection of the surgical site which didn't require the explantation of the mesh, although determining an early hernia relapse. She is submitted by the authors to a surgical intervention for left groin hernia relapse with placement of a polypropylene monofilament fixed with prolene. Six hours after the operation she shows systemic symptoms and local signs of prosthesis infection. Cultural examination of the surgical wound secretion allows the identification of Streptococcus dysgalactiae subspecies equisimilis (SDSE). A therapy with Amoxicillin-Clavulanic Acid and Levofloxacine leads to resolution, in 10 weeks, of the infection.

DISCUSSION

In our case the infection of the new mesh, appearing prematurely, has been probably favoured by obesity and operative time longer than 3 hours. Conservative treatment has been fulfilled by success for the elevated sensitivity of the SDSE bacterium to penicillin and fluoroquinolones.

CONCLUSIONS

Recent epidemiologic studies have demonstrated an increase of infections caused by SDSE, which will probably gain clinical relevance in the next future relatively to surgical prosthetic hernioplasty. In all cases of infection the authors suggest cultural isolation of the casual germ and the execution of the antibiogram because the conservative medical treatment can avoid mesh removal with consequent elevated risk of hernia relapse.

[Gallbladder polypoid lesions. Three clinical cases with difficult diagnosis and literature review]

INTRODUCTION

Gallbladder polypoid lesions occur in 1.3%-6.9% of cases. The preoperative diagnosis between benign, malignant and potentially malignant lesions is difficult. Therefore it is not possible any.

PATIENTS AND METHODS

The Authors describe three cases. The case 1 was a gallbladder diffuse adenomyomatosis; the ultrasound and the CT were of little help in defining preoperatively the nature and the gravity of the thickening. Case 2 was an adenomyomatosis of the fundus: the ultrasound examinations were not able to establish preoperatively lesion's nature, site and dimensions. In the case 3, ultrasounds showed polypoid lesions and calculi concrections not found in colecistectomy.

DISCUSSION

The ultrasound is the most widely used diagnostic tool in the evaluation of gallbladder polypoid lesions; its accuracy is only 66%. CT, which has an accuracy level of 75%, must be carried out there is any possibility of malignant degeneration of the polyp. If doubts persist, a MR, 93% accuracy, is indicated. In selected cases, PET can be of further help.

CONCLUSIONS

The preoperative diagnosis of the nature of gallbladder polypoid lesions is "difficult" and this justifies the lack of consensus on treatment. However, the adenoma-carcinoma sequence, widely discussed in literature, can justifies to the use of CT, MR, PET and surgical treatment after an ultrasound examination.

[A rare cause of acute abdomen: splenic infarction. Case report and review of the literature]

INTRODUCTION

Splenic infarction is a rare cause of acute abdomen. It must be suspected in patient with hematologic diseases or thromboembolic conditions. The most common onset symptom is left-upper quadrant abdominal pain. Additional symptoms include fever and anemia. Laboratory may show elevated white blood cell and platelet counts.

CASE REPORT

A 97-year-old female with a past history of atrial fibrillation presented with left-upper quadrant abdominal pain and fever since 20 days. Laboratory showed elevated white blood cell and platelet counts, increased C-reactive protein and lactate dehydrogenase. Both ultrasonographic and tomographic scans showed a large hypodense area of the spleen. The patient received intravenous antibiotic therapy, which led to significant clinical improvement with discharge 16 days after admission.

DISCUSSION

The diagnosis of splenic infarction is based both on clinical presentation and imaging studies. Angio-computed tomography is the diagnostic procedure of choice. Ultrasonography and conventional radiology are useful in the differential diagnosis with other abdominal and thoracic diseases mimicking splenic infarction. In our case the management was conservative, because the patient was hemodynamically stable and antibiotic therapy could control the sepsis. Moreover, advanced age and poor cardiac and respiratory conditions contraindicated surgery.

CONCLUSIONS

In our case splenic infarction was probably due to a thromboembolic event secondary to atrial fibrillation. In accordance with the literature, we suggest initial conservative therapy. Surgery is indicated only in the presence of complications.

Endoscopic sphincterotomy of the major duodenal papilla in acute relapsing pancreatitis associated with pancreas divisum: a case report

We report a case of acute relapsing pancreatitis associated with pancreas divisum, who underwent major papilla sphincterotomy after failed minor papilla cannulation. Long-term results were satisfactory. The possible explanations of the efficacy of major papilla endoscopic resection in this particular case are discussed.

[Unusual cause of acute abdomen in adult patient: gallstone ileus]

INTRODUCTION

Gallstone ileus is a rare complication of cholecystolithiasis. It causes 1-3% of the mechanical obstructions of the small bowel. It often affects patients between 63 and 85 years old. Pre-operative diagnosis is usually delayed 1-10 days because there is not a specific symptomatology.

CASE REPORT

The authors report the case of a 50 year-old man with diagnosis of mechanical obstruction of the small bowel caused by a voluminous gallstone. Ileal occlusion was showed by CT. The patient underwent to one-stage emergency surgery with enterolithotomy, cholecystectomy and duodenal fistula repair. Patient's recovery was regular and he was discharged fourteen days after surgery.

DISCUSSION

In our case gallstone ileus was diagnosed with a delay of 5 days. Ultrasonography was not able to show the gallbladder. Diagnosis was made by CT, which is the diagnostic gold standard.

CONCLUSION

Patient's performance status influences surgical strategy. In our experience, the patient underwent one-stage surgery because he was considered at low risk. Instead staged procedure with enterolithotomy and delayed cholecystectomy and fistula repair, is performed only in patients at high risk.

[Umbilical primary endometrioma. Case report]

Umbilical primary endometrioma is a rare extra-uterine localization of endometriosis with a documented neoplastic risk. It is often difficult to distinguish primary umbilical endometriosis from other benign and malignant tumors of the abdominal wall. The Authors report a case of umbilical endometriosis in a 36-year old female. Endometriosis was suspected because of the presence of the typical cyclic bleeding and swelling. Abdominal CT excluded the presence of other endometriotic localizations. The umbilical mass was widely excised together with umbilicus, fascia and peritoneum. The tissue defect was primary closed without prosthetic mesh. Histological examination of the specimen showed the presence of endometrial glands with stromal component, compatible with the diagnosis of endometriosis. The Authors suggest that surgery should be performed in the first 3-4 days of the follicular phase, to minimize the risk of diffusion of endometriotic cells. Moreover, the excision should be wide in order to prevent local recurrence.
