Pneumo-peritoneum, pneumo-retroperitoneum and subcutaneous emphysema following endoscopic retrograde cholangiopancreatography with sphincterotomy-an uncommon complication case report.
Endoscopic retrograde cholangiopancreatography (ERCP) is invasive for pancreaticobiliary diseases. Perforation is a rare but severe complication among its associated risks. A 45-year-old female with biliary colic and multiple gallbladder calculi was diagnosed with choledocholithiasis based on imaging showing CBD dilation and gallstones. ERCP was planned for stone removal. Sphincterotomy was performed, but stone retrieval attempts failed, leading to severe pneumo-peritoneum and respiratory compromise. Immediate CBD stenting was done, avoiding surgical intervention. The patient recovered uneventfully, later undergoing laparoscopic cholecystectomy with CBD exploration and stone removal. ERCP-related perforations, rare but severe, involve retroperitoneal air collection. Clinical signs include abdominal discomfort, and imaging confirms diagnosis. Management varies by type, with some requiring surgical repair. Conservative management sufficed in this case, with successful patient recovery. ERCP-related complications like pneumo-peritoneum require prompt diagnosis and conservative management if no perforation is evident.

Tension pneumoperitoneum is a surgical emergency. Although rare, failure to diagnose and treat the condition may be lethal. Hence, being aware of this phenomenon, particularly in scenarios involving cardiopulmonary resuscitation (CPR), is important. Existing literature emphasises immediate abdominal needle decompression as the initial management followed by close monitoring and keeping a low threshold for surgical intervention as a definitive measure. We decided to write up this case report to raise awareness that a tension pneumoperitoneum can result as a complication of CPR, a well-known and widely practiced algorithm.

Review
Complete mesocolic excision for right-sided colon cancer yields larger specimens with higher lymph node harvest. This has caused a reduction in recurrence rates and improved survival. However, the technique remains controversial and has been associated with a higher risk of intraoperative complications. More recently published studies do not indicate that CME is associated with increased postoperative morbidity rates as summarised in this review. More detailed consensus regarding the use of the technique is needed, and future studies should aim for prospective confirmation of the current positive long-term results.

Before the "mesorectal" theory was proposed, the traditional anatomy believed that the "pelvirectal space" belonged to the anal canal and perirectal space, which was independent of the rectal structure, located on both sides of the rectum, above the levator ani, and below the peritoneal reflexion, and was composed of a large amount of fatty tissue filling. With the development of the theory of membrane anatomy and the clarification of the concept of "rectal mesentery", combined with the author's clinical experience, we found that the above-mentioned fat is actually the fat within the mesorectum, as well as the fat tissue of lateral lymph nodes (LLN) such as the internal iliac lymph nodes (No.263) and obturator lymph nodes (No.283) on both sides of the rectal mesentery, rather than the so-called fat tissue within the interstitial space. Therefore, the author believes that the pelvirectal space does not exist. In the anatomical location equivalent to the pelvic rectal space, there is the "superior levator ani space" based on the membrane anatomy theory. From the pelvirectal space to the superior levator anal space, it reflects our further understanding of the anatomy of the rectal mesentery.

To study the influence of neoadjuvant chemoradiotherapy on peritoneal wound recovery after abdominoperineal resection (APR). This was a retrospective cohort study of data of 219 patients who had been pathologically diagnosed with low rectal cancer and undergone APR in the Union Hospital of Tongji Medical College of Huazhong University of Science and Technology between January 2018 and December 2021. Of these patients, 158 had undergone surgery without any pre-surgical treatment (surgery group), 35 had undergone surgery after neoadjuvant chemotherapy (neoadjuvant chemotherapy group), and 26 had undergone surgery after neoadjuvant chemoradiotherapy (neoadjuvant chemoradiotherapy group). The primary outcome was perineal wound complications occurring within 30 days. The status of wound healing was classified into the following three levels: Level A: abnormal wound seepage that improved after wound discharge; Level B: wound infection and dehiscence; and Level C: Level B plus fever. The patients' general condition, tumor status, perianal wound healing level, and intra- and post-operative recovery were recorded. None of the study patients had any complications during surgery. The duration of surgery was 240.0 (180.0-300.0) minutes, 240.0 (225.0-270.0) minutes and 270.0 (240.0-356.2) minutes in the surgery, neoadjuvant chemotherapy, and neoadjuvant chemoradiotherapy groups, respectively (=6.508, =0.039). The rates of perineal wound complications were 34.6% (9/26) and (22.9%, 8/35)in the neoadjuvant chemoradiotherapy group and the neoadjuvant chemotherapy group, being significantly higher than that in the surgery group (10.1%, 16/158). After adjusting for patient age and sex using a logistic regression model, the risk of complications was still higher in the neoadjuvant chemoradiotherapy than in the surgery group (OR=4.6, 95%CI: 1.7-12.7; OR=2.6, 95%CI: 1.0-6.8), these differences being statistically significant (both <0.05). The duration of hospital stay was 9.5 (7.0-12.0) days, 10.0 (8.0-17.0) days and 11.5 (9.0-19.5) days for patients in the surgery, neoadjuvant chemotherapy, and neoadjuvant chemoradiotherapy groups, respectively (=0.569, =0.752). However, after adjusting for patient age and sex by using a generalized linear model, hospital stay was longer in the neoadjuvant chemoradiotherapy than in the surgery group (β [95% CI]: 4.4 [0.5-8.4], =0.028). After surgery, 155 of 219 patients required further adjuvant chemotherapy. A higher proportion of patients with than without wound complications did not attend for follow-up (32.2% [10/31] vs. 16.1% [20/124]); this difference is statistically significant (χ=4.133, =0.023). In patients with low rectal cancer, neoadjuvant radiotherapy may be associated with an increased risk of perineal wound infection and non-healing.

Rectal MRI provides a detailed depiction of pelvic anatomy; specifically, the relationship of the tumor to key anatomic structures, including the mesorectal fascia, anterior peritoneal reflection, and sphincter complex. However, anatomic inconsistencies, pitfalls, and confusion exist, which can have a strong impact on interpretation and treatment. These areas of confusion include the definition of the rectum itself, specifically differentiation of the rectum from the anal canal and the sigmoid colon, and delineation of the high versus low rectum. Other areas of confusion include the relative locations of the mesorectal fascia and peritoneum and their significance in staging and treatment, the difference between the mesorectal fascia and circumferential resection margin, involvement of the sphincter complex, and evaluation of lateral pelvic lymph nodes. The impact of these anatomic inconsistencies and sources of confusion is significant, given the importance of MRI in depicting the anatomic relationship of the tumor to critical pelvic structures, to triage surgical resection and neoadjuvant chemoradiotherapy with the goal of minimizing local recurrence. Evolving treatment paradigms also place MRI central in management of rectal cancer. RSNA, 2024.

Benign multicystic peritoneal mesothelioma (BMPM), also known as multicystic peritoneal mesothelioma (MCPM), is a rare cystic neoplasm arising from the mesothelium lining of the abdominal and pelvic peritoneum. This entity has been disproportionately described in women of reproductive age. Both the etiology and pathogenesis of the condition are not well understood. Preoperative diagnosis is challenging as differentials are varied and include endometriosis, lymphangioma, pseudomyxoma peritonei, cystic adenomatoid tumor, and malignant peritoneal mesothelioma. Management options include cytoreductive surgery (CRS) with or without heated intraperitoneal chemotherapy (HIPEC). In this case report, we highlight the complexity of preoperative diagnosis, presentation, workup, treatment, and management of BMPM. We report the case of a female patient presenting with abdominal pain and imagining consistent with cystic intra-abdominal lesions. After an inconclusive percutaneous biopsy and a multi-disciplinary tumor board discussion, the patient was offered CRS with HIPEC. Intra-operative frozen section indicated benign epithelial lined cysts. CRS and HIPEC were performed. After a second opinion, the lesions were confirmed by pathology and immunohistochemistry to be BMPM. In this report, we discuss the gold standard of care for patients with BMPM to improve the disease control rate. This pathway is proposed in our study, and, thus, we conclude that BMPM should be considered in the differential diagnosis of patients presenting with symptomatic multiple intraperitoneal cystic lesions.

Review
Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) is an emerging technique for delivering chemotherapy directly to the peritoneum via a pressurized aerosol. Its growing attention stems from its effectiveness in treating peritoneal carcinomatosis (PC) originating from various primary tumors, with gastric cancer (GC) being among the most prevalent. This study aimed to systematically investigate PIPAC's therapeutic role in gastric cancer peritoneal metastasis (GCPM). The systematic review and meta-analysis followed the PRISMA 2020 guidelines, searching Pubmed, Web of Science, and SCOPUS databases. The meta-analysis of relative risks and mean differences compared patients undergoing one or two PIPAC sessions with those completing three or more, assessing various outcomes. Eighteen studies underwent qualitative analysis, and four underwent quantitative analysis. Patients with three or more PIPAC procedures had shorter hospital stays (MD = -1.2; 95%CI (-1.9; -0.5); < 0.001), higher rates of histopathological response (RR = 1.77, 95%CI 1.08; 2.90; = 0.023), and significantly improved overall survival (MD = 6.0; 95%CI 4.2; 7.8; < 0.001). Other outcomes showed no significant differences. PIPAC demonstrated efficacy in carefully selected patients, enhancing histopathologic response rates and overall survival without prolonging hospital stays. This study underscores the necessity for randomized controlled trials and precise selection criteria to refine PIPAC's implementation in clinical practice.

Review
BACKGROUND
Atypical Spitz tumor (AST) is an intermediate category among Spitz melanocytic neoplasms. Sentinel node biopsy (SNB) has been proposed in the clinical management of AST patients, but this approach remains the subject of debate. This systematic review aims to summarize the available evidence on SNB procedures in AST patients.
METHODS
A comprehensive search was conducted, including MEDLINE/Pubmed, EMBASE, and SCOPUS, through April 2023. Case series, cohort studies, and case-control studies of AST patients were eligible for inclusion. PRISMA guidelines were followed.
RESULTS
Twenty-two studies with a total of 756 AST patients were included. The pooled SNB prevalence was 54% (95% CI 32 to 75%), with substantial heterogeneity (I2 90%). The pooled SNB+ prevalence was 35% (95% CI 25 to 46%) with moderate heterogeneity (I2 39%). Lymphadenectomy was performed in 0-100% of SNB+ patients. Overall survival rates ranged from 93% to 100%, and disease-free survival ranged from 87% to 100% in AST patients. Overall and disease-free survival rates were 100% in SNB patients. Pooled survival estimates were not calculated due to the heterogeneous timing of the survival assessment and/or the small size of the subgroups. All studies clearly reported inclusion criteria and measured the condition in a standard way for all participants, but only 50% indicated valid methods for the identification of the condition.
CONCLUSIONS
The oncologic behavior of AST is related to an almost always favorable outcome. SNB does not seem to be relevant as a staging or prognostic procedure, and its indication remains debatable and controversial.

Microbial infection-induced sepsis causes excessive inflammatory response and multiple organ failure. An effective strategy for the treatment of sepsis-related syndromes is still needed. Rosuvastatin, a typical β-hydroxy β-methylglutaryl-CoA reductase inhibitor licensed for reducing the levels of low-density lipoprotein cholesterol in patients with hyperlipidemia, has displayed anti-inflammatory capacity in different types of organs and tissues. However, its effects on the development of sepsis are less reported. Here, we found that the administration of Rosuvastatin reduced the mortality of sepsis mice and prevented body temperature loss. Additionally, it inhibited the production of inflammatory cytokines such as tumor necrosis factor (TNF-α), Interleukin-6 (IL-6), interleukin-1β (IL-1β), and migration inhibitory factor (MIF) in peritoneal lavage supernatants of animals. The increased number of mononuclear cells in the peritoneum of sepsis mice was reduced by Rosuvastatin. Interestingly, it ameliorated lung inflammation and improved the hepatic and renal function in the sepsis animals. Further experiments show that Rosuvastatin inhibited lipopolysaccharide (LPS)-induced production of proinflammatory cytokines in RAW 264.7 macrophages by preventing the activation of nuclear factor kappa-B (NF-κB). Our findings demonstrate that the administration of Rosuvastatin hampered organ dysfunction and mitigated inflammation in a relevant model of sepsis.
