Acute Chyloperitoneum with Small Bowel Volvulus: Case Series and Systematic Review of the Literature.

Introduction: Chyloperitoneum arises from lymph leakage into the abdominal cavity, leading to an accumulation of milky fluid rich in triglycerides. Diagnosis can be challenging, and mortality rates vary depending on the underlying cause, with intestinal volvulus being just one potential acute cause. Despite its rarity, our case series highlights chyloperitoneum associated with non-ischemic small bowel volvulus. The aims of our study include assessing the incidence of this association and evaluating diagnostic and therapeutic approaches. Material and Methods: We present two cases of acute abdominal peritonitis with suspected small bowel volvulus identified via contrast-enhanced computed tomography (CT). Emergency laparotomy revealed milky-free fluid and bowel volvulus. Additionally, we conducted a systematic review up to 31 October 2023, identifying 15 previously reported cases of small bowel volvulus and chyloperitoneum in adults (via the PRISMA scheme). Conclusions: Clarifying the etiopathogenetic mechanism of chyloperitoneum requires specific diagnostic tools. Magnetic resonance imaging (MRI) may be useful in non-emergency situations, while contrast-enhanced CT is employed in emergencies. Although small bowel volvulus infrequently causes chyloperitoneum, prompt treatment is necessary. The volvulus determines lymphatic flow obstruction at the base of the mesentery, with exudation and chyle accumulation in the abdominal cavity. Derotation of the volvulus alone may resolve chyloperitoneum without intestinal ischemia.

Intestinal Perforation in a patient with peritoneal carcinomatosis from colon cancer treated with Regorafenib. Description of a case and review of the literature.

Regorafenib is a multikinase inhibitor approved for treatment of patients with metastatic Colo-Rectal Cancer (mCRC) and Gastro-Intestinal Stromal Tumor (GIST) progression after the administration of other tyrosine-kinase inhibitors such as imatinib and sunitinib. Only a handful of severe side effects such as intestinal perforations and fistulas have been described in the literature in patients undergoing multikinase inhibitor treatment. We report a case of a patient with peritoneal mCRC who experienced an intestinal perforation during the administration of Regorafenib and review the literature. A 48-year-old man with previously resected sigmoid colon cancer and peritoneal metastatic disease under Regorafenib treatment presented to our Emergency Department with severe abdominal pain and asthenia. Abdominal X-ray and contrast-enhanced computed tomography examination revealed an intestinal perforation. The patient underwent emergency surgery which demonstrated acute diffuse peritonitis, necrosis, and perforation of a distal ileal loop affected by peritoneal metastatic disease. The necrosis of peritoneal implants on bowel walls could be regarded as a potential factor leading to intestinal perforation in metastatic colorectal cancer patients undergoing Regorafenib treatment complaining of severe abdominal pain and asthenia. Surgeons, radiologists and oncologists should always keep in mind this rare adverse event during Regorafenib administration. Appropriate diagnostic tests and treatments should be carried out.

Percutaneous trans-stomal jejunostomy: a new technique.

AIM: We propose a new technique for feeding a malnourished patient with a "high" double-barrel jejunostomy (at about 60 cm from the Treitz Ligament). The procedure aims to restore an adequate nutritional state maintaining a correct diet for 24 h a day, without complications and without interfering with the normal activity of the nurses caring for the stoma. METHOD: Using local anesthesia, we introduced a Reverdin needle through the efferent loop of jejunostomy and externalized it through the skin, medially from jejunostomy of about 10 cm. Using this guide, we inserted an enteral feeding tube with a blunt tip and then introduced it through the efferent loop to reach about 40 cm distantly into the bowel. RESULTS: The stoma output decreased from 3 to 1.5 L/day; kidney status was restored to normal function. CONCLUSION: The main advantages are the minimal invasiveness of the implantation procedure, the possibility of nutrition during all 24 h, and the easy management by nurses.

Comparison and validation of three difficulty scoring systems in laparoscopic liver surgery: a retrospective analysis on 300 cases.

BACKGROUND: Difficulty scores (DSs) have been proposed to rate laparoscopic liver resection (LLR) technical difficulty increasing surgical safety. The aim of the study was to validate three DSs (Hasegawa, Halls and Kawaguchi) and compare their ability to predict technical difficulty and postoperative outcomes. MATERIALS AND METHODS: All patients who underwent LLR from January 2006 to January 2019 were analyzed. Exclusion criteria were cyst fenestrations, thermal ablation, missing data for the computation of the DS and a follow-up < 90 days. RESULTS: The population comprised 300 patients. The DS distribution in the study population was: Halls low 55 (18.3%), moderate 82 (27.3%), high 111 (37%) and extremely high 52 (17.3%); Hasegawa low 130 (43.3%), medium 105 (35%) and high 65 (21.7%); Kawaguchi Grade I 194 (64.7%), Grade II 47 (15.7%) and Grade III 59 (19.7%). Hasegawa and Kawaguchi showed the strongest correlation (r = 0.798, p < 0.001). Technical complexity, evaluated using the Pringle maneuver, Pringle time, blood loss and operative time, increased significantly with Hasegawa and Kawaguchi score classes (p < 0.001 for all comparisons). None of the scores properly stratified postoperative complications. The highest Kawaguchi (23.7% grade III vs. 13.7% grades I and II, p = 0.057) and Hasegawa (24.6% high vs. 13.2% low/medium, p = 0.025) classes had a higher overall morbidity rate than medium-low ones. CONCLUSIONS: Kawaguchi and Hasegawa scores predicted LLR's technical difficulty. None of the scores discriminated the postoperative complication risk of low classes compared with medium ones.

Preoperative risk score for prediction of long-term outcomes after hepatectomy for intrahepatic cholangiocarcinoma: Report of a collaborative, international-based, external validation study.

PURPOSE: A preoperative risk score (PRS) to predict outcome of patients with intrahepatic cholangiocarcinoma treated by liver surgery could be clinically relevant.To assess accuracy for broadly adoption, external validation of predictive models on independent datasets is crucial. The objective of this study was to externally validate the score for prediction of long-term outcomes after liver surgery for intrahepatic cholangiocarcinoma proposed by Sasaki et al. and based on preoperative albumin, neutrophil-to-lymphocytes-ratio, CA19-9 and tumor size. METHODS: Patients treated by liver surgery for intrahepatic cholangiocarcinoma at 11 international HPB centers from 2001 to 2018 were included in the external validation cohort. Harrell's c-index and Hosmer-Lemeshow analyses were used to test PRS discrimination and calibration. Kaplan-Meier curve for risk groups as described in the original study were displayed. RESULTS: A total of 355 patients with 174 deaths during the follow-up period (median = 41.7 months, IQR 32.8-50.6) were included. The median PRS value was 14.7 (IQR 10.7-20.6), with normal distribution across the cohort. A Cox regression on PRS covariates found coefficients similar to those of the derivation cohort, except for tumor size. Measures of discrimination estimated by Harrell's c-index was 0.61(95%CI:0.56-0.67) and Hosmer-Lemeshow p = 0.175. The Kaplan-Meyer estimation showed reasonable discrimination across risk groups, with 5years survival rate ranging from 20.1% to 0%. CONCLUSION: In this external validation cohort, the PRS had mild discrimination and poor calibration performance, similarly to the original publication. Nevertheless, its ability to identify different classes of risk is clinically useful, for a better tailoring of a therapeutic strategy.

Cystic lymphangioma of the pancreas: a hard diagnostic challenge between pancreatic cystic lesions-review of recent literature.

Lymphangiomas are rare congenital benign tumors arising from the lymphatic system. The incidence of this disease in the pancreas is extremely rare, accounting for less than 1% of these tumors. Before introducing the review we reported a case of a 67-year-old woman with cystic lymphangioma of the pancreas. We reported the radiological investigations carried out preoperatively and the treatment performed. The review tries to identify the features described in literature of the pancreatic lymphangioma. We have performed a PubMed research of the world literature between January 1st 2000, to November 31st 2017, using the keywords [Lymphangioma pancreas], [diagnosis], [CT lymphangioma] and [MRI lymphangioma]. We have found 158 articles, of which about 100 were case reports. Based on our search criteria, we have identified 31 pancreatic lymphangioma in literature reporting their imaging characteristics. According to our report and to several authors in literature the diagnosis of cystic pancreatic lymphangioma should be considered as a differential diagnosis of pancreatic cystic lesions (PCLs). The role of imaging exams (CT and MRI) can help to identify and suspect this possibility of diagnosis. The endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) can have a potential role to reach the correct diagnosis.

Rectal perforation by inadvertent ingestion of a blister pack: A case report and review of literature.

The accidental ingestion of a foreign body (FB) is a relatively common condition. In the present study, we report a peculiar case of rectal perforation, the first to our knowledge, caused by the inadvertent ingestion of a blister pill pack. The aim of this report is to illustrate the difficulties of the case from a diagnostic and therapeutic viewpoint as well as its unusual presentation. A 75-year-old woman, mentally impaired, arrived at our emergency department in critical condition. The computed tomography scan revealed a substantial abdominopelvic peritoneal effusion and free perigastric air. The patient was therefore submitted to an urgent exploratory laparotomy; a 2-cm long, full-thickness lesion was identified in the anterior distal part of the intraperitoneal rectum. Hence, we performed a Hartmann's procedure. Because of her critical condition, the patient was eventually transferred to the Intensive Care Unit, where she died after 10 d, showing no surgical complication. The ingestion of FBs is usually treated with observation or endoscopic removal. Less than 1% of FBs are likely to cause an intestinal perforation. The intestinal perforation resulting from the unintentional ingestion of an FB is often a difficult challenge when it comes to treatment, due to its late diagnosis and the patients' deteriorated clinical condition.

Gastric inflammatory fibroid polyp tumor with acute intestinal obstruction-Vanek's tumor can mimick a giant gastrointestinal stromal tumor or a gastric lymphoma.

An inflammatory fibroid polyp (IFP) is a solitary rare benign neoplasm of the gastrointestinal tract, frequently located in the gastric antrum. IFPs account for about 0.1% of all gastric polyps. We report a case of a giant gastric inflammatory polyp of 2.5 cm × 7 cm that determines a gastric outlet obstruction called "ball valve syndrome" mimicking a gastrointestinal stromal tumor (GIST) and a gastric lymphoma, with an intestinal obstruction of high origin. Therefore, due to acute presentation we have decided to submit the patient to a subtotal gastrectomy. The patient was discharged two weeks later, asymptomatic. At 14 months of follow-up, patient is disease free at abdominal CT and OGDS. Depending on their size and location, IFPs can be associated with unspecific symptoms. Giant IFPs of the gastric antrum or the duodenum can determine an intermittent gastric outlet obstruction called "ball valve syndrome". Endoscopic biopsies are unhelpful and right diagnosis can be reached only with resection. In fact, only about 10% of the gastric lesions are diagnosed correctly prior to resection. Surgical treatment with complete resection with safe margins is curative. Giant IFPs are rare benign lesions whose atypical presentation can mimic GISTs, lymphomas or carcinomas. Clinical and radiological findings may not clarify the right diagnosis until histopathological evaluation aided with immunohistochemical analysis. The resection of IFPs with negative margins is curative with a good clinical outcome. In acute presentation, like in our case, surgery is the mainstay of treatment.

Evaluation of cisplatin plasma levels in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Introduction Peritoneal surface malignancies have long been regarded as incurable, however, they can be treated with cytoreductive surgery in addition to hyperthermic intraperitoneal chemotherapy. This approach is associated with an increase in morbidity and mortality, unless hyperhydration is provided in a timely manner. Methods Cisplatin (CDDP) is the most widely used chemotherapeutic agent. Plasma levels of cisplatin (CDDP), a widely used chemotherapeutic agent, were measured before, during, and after the procedure. This was done in order to identify the window of highest risk as a function of drug concentrations, assuming a dose-dependent effect. Results Plasma levels of CDDP peak during perfusion. The concentration remains high until the 4th post-operative day and returns to pre-operative levels by the 7th post-operative day. Conclusions Our findings suggest that ensuring hyperhydration as well as infusing albumin and fresh frozen plasma may be of particular value for at least the first 4 days after the procedure.

Wernicke encephalopathy as rare complication of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

BACKGROUND: Peritoneal carcinomatosis of gastric origin is a frequent event with poor survival. A new promising approach is the association of the Cytoreductive Surgery (CRS) with the Hyperthermic Intraperitoneal Chemotherapy (HIPEC), which yet is characterized by high morbidity and mortality. We report, to our knowledge, the first case of Wernicke Encephalopathy (WE) complicating CRS plus HIPEC. WE, caused by a deficiency of thiamine, is characterized by ataxia, ocular motor cranial neuropathies and changes in consciousness. METHODS: A patient affected by gastric cancer with peritoneal seeding, submitted to CRS plus HIPEC, in 4th post-operative day had manifested the appearance of flapping tremors, with positive manoeuvre of Mingazzini, impaired vision and mental confusion. The brain Magnetic Resonance Imaging (MRI) confirmed the clinical suspicion of WE. Even though the appropriate therapy was promptly applied, the patient died in 10th post-operative day. CONCLUSION: WE is an uncommon neurological disorder. Only 16% of these patients inadequately treated recover fully, with a mortality rate of 10-20%. We consider useful to report this case, because it is the first time that WE is correlated to CRS plus HIPEC.

Giant retroperitoneal liposarcoma: Case report and review of the literature.

AIM: Retroperitoneal soft-tissue sarcomas are relatively uncommon diseases, the most frequent histotype, ranging from 20% to 45% of all cases, is represented by liposarcoma, which is a hard-to treat condition for its local aggressiveness and clinical aspecificity. PRESENTATION OF CASE: We report a case of a 64-years-old woman who underwent surgical resection for a giant pleomorphic retroperitoneal liposarcoma. DISCUSSION: Currently chemotherapy for retroperitoneal soft-tissue sarcomas is no effective, and radiotherapy has limited efficacy due to the toxicity affecting adjacent intra-abdominal structures, showed validity only in case of high-grade malignancy by reducing local recurrence, but with no advantage in overall survival. Nowadays only, the complete surgical resection remains the most important predictor of local recurrence and overall survival. CONCLUSION: The removal of a retroperitoneal sarcoma of remarkable size is a challenge for the surgeon owing to the anatomical site, to the absence of an anatomically evident vascular-lymphatic peduncle and to the adhesions contracted with the contiguous organs and with the great vessels. Therefore, we believe that, particularly for large-size diseases associated to high-grade malignancy, a complete surgical resection with removal of the contiguous intra and retroperitoneal organs when infiltrated represents the only therapeutic option to obtain a negative margin and therefore an oncological radicality.

Short-term outcome of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: preliminary analysis of a multicentre study.

AIM: To assess the incidence of morbidity and mortality of Cytoreductive Surgery plus Hyperthermic Intraperitoneal Chemotherapy. PATIENTS AND METHODS: A retrospective multicentric study was performed. Six hundred and eighty-three patients were recorded. Predictors of morbidity and mortality were evaluated with univariate and multivariate analysis. RESULTS: In univariate analysis, older age, Eastern Cooperative Oncology Group score, a greater value of Peritoneal Cancer Index (PCI) and sub-optimal cytoreduction were correlated with higher mortality, while older age, presence of ascites, ovarian origin of carcinomatosis, closed technique, a greater value of PCI, longer operative time and sub-optimal cytoreduction were predictors of higher morbidity. In multivariate analysis, older age and a greater value of PCI were correlated with higher mortality; older age, ovarian origin of tumor, presence of ascites, closed technique and longer operative time were predictors of higher morbidity. CONCLUSION: Careful patient selection has to be performed to improve clinical outcomes.

Relapsed metachronous pancreatic metastasis from renal cell carcinoma (RCC): report of a case and review of literature.

AIM: The pancreas is a preferred site of metastasis from renal cell carcinoma (RCC), that may occur even after many years from a radical nephrectomy. Surgical R0 resection remains the only potentially curative treatment for solitary tumor. The possibility of a multifocality of the lesions (20-45%) must be considered. MATERIAL OF STUDY: We report a case of metachronous pancreatic metastasis from RCC that occurred twice. After five years from a right polar inferior nephrectomy for a RCC, two nodular lesions were identified in the body-tail of the pancreas and were treated with distal pancreatectomy and splenectomy. After six months the CT imaging revealed a nodular lesion of few millimeters in the residual pancreatic body; we followed the slow growth and in October 2012, when the size reached 2 cm, the patient was operated to remove the residual portion of pancreatic body. After 16 months of follow-up the patient is well and there isn't relapse of disease. DISCUSSION: Patients with metachronous pancreatic lesions represent a particular group with a more indolent course of RCC, the appearance of metastases after a prolonged interval from nephrectomy is related to a more favorable prognosis. Radical lymph-node dissection is not necessary for the uncommon involvement of peripancreatic nodes, condition that explains the positive outcomes achieved with surgery. CONCLUSION: Patients with resected metastasis present an 88% survival rate at 5 years versus 47% observed in nonoperated patients; studies provide encouraging results in survival and quality of life of surgically treated patients.

Cytoreductive surgery plus bicavitary chemohyperthermia as treatment of pseudomixoma peritonei with pleural extension. A case report and review of the literature.

AIM: Intrathoracic extension in patients with pseudomixoma peritonei is a rare event, but spread of the tumour beyond the abdomen in to pleuropulmonary cavity has been reported. MATERIALS AND METHODS: We report a case of a 50-years-old woman with synchronous pleural manifestation of pseudomixoma peritonei by a mucinous ovarian cancer. During the abdominal cytoreductive surgery an extensive disease under the right hemidiaphragm was noted, requiring partial diaphragmatic resection. Once the pleural space was entered,mucinous neoplastic implants on the pleural surface was observed. The diaphragmatic defect was left open during the hyperthermic chemoperfusion to treat both the pleural and peritoneal surfaces. After a postoperative course uneventful she died after 6 months for a myocardial infarction, in presence of a left side pleural effusion with a positive cytology for high-grade malignant cells with a smear background contained wispy mucin. DISCUSSION: Despite the aggressive spread of the pseudomixoma peritonei within the peritoneal cavity, lymphatic and hematogenous metastasis are rare. However, extension of disease into pleuropolmonary cavity has been well described as pleural effusion or pleuropulmonary metastases. This is the first report in literature, to our knowledge, in which the thoracic extension is due to a mucinous ovarian cancer, and is the second case in which a simultaneous bicavitary hyperthermic chemoperfusion was done as a management option for thoracic extension of pseudomixoma peritonei. CONCLUSION: Due to the rarity of the thoracic involvement by pseudomixoma peritonei, its correct treatment is still unclear. Simultaneous cytoreductive surgery associated to intraoperative intraperitoneal and intrathoracic chemohyperthermia can be a potential therapeutic option for these patients.

The role of prophylactic hyperthermic intraperitoneal chemotherapy in the management of serosal involved gastric cancer.

BACKGROUND: Peritoneal carcinomatosis of gastric origin is associated with poor survival. The use of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) did not significantly improve the survival of patients with this disease. A promising approach can be based on the use of HIPEC as prophylaxis of peritoneal dissemination. PATIENTS AND METHODS: From our database, we have sampled 12 patients with advanced gastric cancer. In all cases, a D2 total gastrectomy was performed, associated with splenectomy in four cases. All patients were submitted to HIPEC. RESULTS: Morbidity and mortality were 33.3% and 8.3%, respectively. The median survival was 24 months, with only one case (8.3%) of peritoneal recurrence. CONCLUSION: In light of our experience and supported by literature data, we can affirm that HIPEC has a potential role in the prevention of gastric carcinomatosis. Certainly further studies are required on a larger scale to validate this new but promising approach.

Metastasis of the gallbladder from the breast cancer.

AIM: Metastatic lesions of the gallbladder are an infrequent clinical condition. The metastatic lesions of gallbladder from primary breast tumors are rarely described in literature. MATERIAL OF STUDY: We report a case of an 83-year-old woman who underwent cholecystectomy for cholelithiasis by video laparoscopy (VL), and in whom a metastatic lesion was detected at the histological examination of surgical specimen. For this reason, the patient was subjected to diagnostic-instrumental investigation with the aim of detecting the primary tumor, which showed the presence of infiltrating lobular carcinoma, pleomorphic variety, in the upper outer quadrant of the right breast. DISCUSSION: Breast cancer and in particular the histological type "ductal infiltrating" is frequently associated with locoregional and distant metastases, the latter especially to bones, liver, lungs and central nervous system. An analysis of literature was conducted on secondary lesions of the gallbladder from breast cancer that has allowed us to confirm the rarity of this disease only described in 18 patients: 12 from infiltrating lobular, 1 ductal origin and 2 mixed ductal and lobular infiltrating. CONCLUSIONS: The most frequent tumor histology associated with the above-mentioned metastatic localization is the metastatic infiltrating lobular carcinoma. Clinically speaking, it is difficult to suspect a metastatic localization from primary breast cancer in the gallbladder, but it is necessary to be well aware of the possibility of metastasis and to bear this in mind during the follow-up of patients with breast cancer. Although cholecystectomy is regarded as a palliative treatment in patients with metastasis in the gallbladder from breast cancer, it is intead recommended in symptomatic cases.
