Impact of the Combination of Anamorelin and Rehabilitation on Functional and Nutritional Outcomes in Patients with Cancer Cachexia.

Cancer cachexia, characterized by the progressive loss of skeletal muscle mass, leads to functional impairment and poor prognosis. Anamorelin is approved for treating cancer cachexia in Japan; however, the factors influencing its discontinuation and the impact of combining anamorelin with rehabilitation remain unclear. Therefore, we retrospectively analyzed 82 patients with cancer cachexia to identify factors associated with anamorelin discontinuation and assess changes in nutritional status and motor function using non-dominant handgrip strength after 12 wk. Patients received outpatient rehabilitation, combining resistance and aerobic training every two weeks, alongside anamorelin therapy. Our findings indicate that patients with an ECOG performance status of 1 or 2 were less likely to continue anamorelin therapy for 12 wk compared to those with a performance status of 0 (odds ratio 2.71; 95% CI 1.05 - 7.00; p = 0.040). Significant improvements were observed in body weight (48.8 to 53.7 kg, p < 0.001), skeletal muscle mass (6.4 to 6.9 kg/m2, p < 0.001), FAACT score (11.5 to 18.0, p < 0.001), and non-dominant handgrip strength (20.5 to 21.7 kg, p = 0.018) after 12 wk. Early initiation of anamorelin with regular rehabilitation is recommended to enhance nutritional status and motor function in patients with cancer cachexia.

Enhanced safety in central venous catheterization performed by Japanese board-certified pediatric surgeons: a retrospective single-center study.

PURPOSE: Board certification by the Japanese Society of Pediatric Surgeons is awarded to pediatric surgeons with substantial surgical experience and academic achievement. However, to date, the surgical performance or outcomes of certified surgeons have not been reported. This study examined the relationship between board certification and surgical outcomes of central venous catheterization. METHODS: This retrospective single-center study was conducted between April 2017 and May 2024. Patients were classified based on whether their procedures were performed by board-certified or non-certified surgeons, and their backgrounds and surgical outcomes were compared. In addition, multivariate analysis was performed to identify the factors associated with prolonged operative time. RESULTS: This study included 112 procedures: 26 performed by board-certified surgeons and 86 performed by non-certified surgeons. There were no significant differences in the age, sex, weight, or primary diagnosis between the groups; however, surgery-associated complications were significantly more common in the non-certified surgeon group than in the board-certified surgeon group (15.1% vs. 0%, P = 0.036). In addition, factors independently associated with a prolonged operative time included weight < 10 kg, left-sided approach, implantable port device use, and < 7 years of postgraduate experience for the surgeon. CONCLUSION: Board certification was associated with a significant reduction in surgery-associated complications during central venous catheterization.

Factors prolonging the operative time for transumbilical laparoscopic-assisted appendectomy in pediatric patients: a retrospective single-center study.

PURPOSE: Transumbilical laparoscopic-assisted appendectomy (TULAA) is one of the first endoscopic surgeries performed by trainee pediatric surgeons. While the operative time is generally shorter than for conventional laparoscopic appendectomy, the indications for this procedure are unclear and many unknown factors can prolong the operative time. We conducted this study to identify the factors that may prolong the operative time for TULAA. METHODS: This retrospective, single-center study was conducted between 2015 and 2023. We performed multivariate analysis to identify the factors associated with prolonged operative time by analyzing TULAA procedures performed by trainees. RESULTS: The study included 243 patients. The median operative time was 84 min (interquartile range, 69-114 min). Multivariate analysis revealed that an increased body mass index, elevated C-reactive protein level, a history of conservative treatment for acute appendicitis, and appendix perforation, for the patient; < 6 years' experience since graduation for the operating surgeon; and lack of board certification as a supervisor from the Japanese Society of Pediatric Surgeons for the attending surgeon were independent risk factors for prolonging the operative time. CONCLUSION: Having an attending surgeon with board certification as a supervisor by the Japanese Society of Pediatric Surgeons contributes to reducing the operative time required for TULAA.

Laparoscopic repair of Morgagni hernia by primary closure with extra-abdominal suture: a case report and review of the literature.

We report a case of a Morgagni hernia repaired by primary closure with an extra-abdominal suture. Moreover, we reviewed cases of laparoscopically repaired Morgagni hernia, in which the size of the hernia defect was known, to establish a size criterion for mesh utilization. An 87-year-old woman presented to our hospital with right upper abdominal pain and vomiting. She had no history of abdominal surgery or trauma. Chest radiography and computed tomography (CT) revealed a Morgagni hernia, with the stomach and transverse colon herniated into the right chest cavity. Initially, an endoscopic repair was performed for the herniated stomach due to her age, which was successful. However, she had a recurrence 2 days later, prompting us to perform a semi-emergent laparoscopic surgery. Laparoscopic examination revealed a Morgagni defect, with the omentum, transverse colon, and stomach herniated, with the stomach reduced by pneumoperitoneum. Fortunately, the herniated organs could be easily relocated into the abdomen with no adhesions. The hernia defect measured 6 x 3 cm. We performed primary closure with an extra-abdominal suture. No sac resection was performed. The operation lasted 98 min. Oral intake was initiated on postoperative day 1, and the patient was discharged on postoperative day 3 without complications. Chest radiography and CT scans at 1 month postoperatively showed no recurrence, and the patient remained asymptomatic at the 9-month follow-up examination. According to our review findings, primary closure is an efficient method for small hernia defects (rule of thumb: width, <4 cm; length, <7 cm).

Factors contributing to prolonged operative time for laparoscopic cholecystectomy performed by trainee surgeons: a retrospective single-center study.

PURPOSE: Laparoscopic cholecystectomy for a benign disease is often the initial endoscopic surgery performed by trainee surgeons. However, a lack of surgical experience is associated with prolonged operative times, which may increase the risk of postoperative complications and poor outcomes. This study aimed to identify the factors associated with prolonged operative times for laparoscopic cholecystectomy performed by inexperienced surgeons. METHODS: This retrospective single-center study was conducted between January 2018 and December 2023. We performed a multivariate analysis to identify the factors associated with prolonged operative time by analyzing elective cases of laparoscopic cholecystectomy performed by surgeons with limited experience. RESULTS: The study included 323 patients, subjected to a median operative time of 89 min. Multivariate analysis identified that patient characteristics such as male sex, increased body mass index, and a history of conservative treatment for cholecystitis, as well as operating surgeon's post-graduation years (< 4 years), and an attending surgeon without endoscopic surgical skill certification from the Japan Society of Endoscopic Surgery, were independent risk factors for a prolonged operative time. CONCLUSION: Our findings suggest that endoscopic surgical skill-certified attending surgeons have excellent coaching skills and mitigate the operative time for elective cholecystectomy.

Polymer clip granuloma mimicking lymph node recurrence: a case report.

BACKGROUND: Foreign body granulomas are postoperative inflammatory reactions to surgical materials within the body. Traditionally, sutures have been the leading cause of foreign body granulomas in the abdomen, commonly referred to as "suture granuloma". However, the use of polymer clips in modern surgeries has introduced new challenges, and reports of intra-abdominal foreign body granulomas caused by surgical clips are limited. Herein, we present a case of an intra-abdominal foreign body granuloma formed due to polymer clips. CASE PRESENTATION: A 45-year-old woman who underwent laparoscopic resection for sigmoid colon adenocarcinoma subsequently developed a suspected lymph node recurrence during follow-up. Imaging showed an enlarging mass adjacent to the inferior mesenteric artery with increased fluorodeoxyglucose uptake. Laparoscopic surgical resection revealed the formation of a foreign body granuloma in response to the polymer clips. CONCLUSIONS: This case suggests that nonabsorbable polymer clips can induce granulomatous reactions postoperatively, and the appearance of lymph node recurrence may be foreign body granulomas.

Recurrent cholangitis and bacteraemia due to Edwardsiella tarda: a case report.

Edwardsiella tarda is typically isolated from aquatic environments. It rarely causes infections in humans. Edwardsiella tarda infections in humans result from the consumption of infected or contaminated food. Here, we present a case of recurrent cholangitis and bacteraemia associated with E. tarda. An 82-year-old man with no history of seafood inoculation was admitted to our hospital because of difficulty in moving his body. The patient was diagnosed with cholangitis, and the blood culture revealed the presence of E. tarda. The patient underwent bile duct stenting and received antibiotic therapy for 14 days. Forty-four days after discharge, cholangitis recurred, and blood culture again showed the presence of E. tarda. The patient underwent bile duct stenting and antibiotic therapy for 11 days. No cholangitis or bacteraemia associated with E. tarda was observed in the following 3 years. Our case strongly suggests that colonization with E. tarda results in recurrent cholangitis and bacteraemia.

Cephalic Vein Cut-Down Method for Totally Implantable Venous Access Ports: A Single-Institution Experience.

BACKGROUND: The widespread use of chemotherapies has increased the need for totally implantable venous access ports (TIVAPs). Previously, the subclavian puncture approach with the landmark technique was the most used implantation method; however, it has been related to early complications such as pneumothorax, hemothorax, and arterial puncture. Therefore, a safer implantation method is required. This study aimed to assess the safety and efficacy of the cephalic vein cut-down method used in our institution. METHODS: Patients who underwent TIVAPs implantation using the cephalic vein cut-down method as the first choice between January 1, 2018, and December 31, 2020, were included in this study. We retrospectively evaluated the technical success rates, operation times, and early complications. RESULTS: This study included 221 adult patients (men, 129; women, 92), with a mean age of 68 ± 11 years. The mean body mass index (BMI) was 21 ± 4 kg/m2. A total of 213 patients (96.4%) had malignant tumors that required chemotherapy. The mean postoperative follow-up period was 659 ± 442 days (range, 5-1,698 days). A total of 127 patients (57.5%) died during the follow-up period. The technical success rate was 86.4% (191/221). There were 30 failures, 24 of which were converted to the subclavian vein puncture approach. The mean operation time was 53 ± 21 min. Early complications were observed in 4 (1.8%) patients, corresponding to an incidence of 0.028 complications/1,000 catheter days. One patient had an unintended arterial puncture; however, it was not a result of the cephalic vein cut-down method but a secondary result of the subclavian vein puncture. No complications of pneumothorax, hemothorax, or arterial puncture were observed with the cephalic vein cut-down method. CONCLUSIONS: This study showed that the cephalic vein cut-down method for TIVAPs had an acceptable success rate and fewer early complications than the conventional puncture techniques.

Simultaneous total robotic right hemicolectomy and right partial nephrectomy.

The incidence of synchronous colorectal and renal cancers is reportedly as low as 0.33%. Simultaneous surgery for multi-organ cancers has been reported to have several advantages if tolerated by the patient. In addition, robotic surgery has gained wide application in various fields, but few reports exist on total robotic surgery involving multiple organ resections. We performed simultaneous total robotic surgery on a patient with combined colorectal and renal cancers. Before surgery, we examined the procedure with the surgical team, shared a portion of the trocar site without impairing the operability of the robotic surgery and performed the surgery safely. Further examinations are required to standardize the procedure for simultaneous robotic surgery for multi-organ cancers.

A case of inferior phrenic artery injury after chest drainage treated laparoscopically.

Chest drainage is a commonly performed surgical procedure. However, caution is required when performing this procedure because of its serious complications. One complication is vascular injury. Endovascular treatment has been prioritized in patients requiring hemostasis. We report the case of an 87-year-old woman, who presented to our hospital with dyspnea caused by massive pleural effusion. We decided to perform chest tube placement for the purpose of diagnosis and treatment. The inferior phrenic artery was injured during chest drainage, resulting in hemorrhagic shock. Catheter embolization was considered, but it was deemed difficult due to the patient's abnormal blood vessel. Instead, hemostasis was induced via laparoscopy. This is the first report on the safety of laparoscopic hemostasis for inferior phrenic artery bleeding. By devising, we were able to perform hemostatsis safely under laparoscopy.

A Comparison of Sexual Function in Male Patients with Anorectal Malformations Between the Conventional and Laparoscopic Approaches.

Aim: To compare the incidence of erectile dysfunction and ejaculatory anomalies in male patients with anorectal malformation (ARM) after treatment with the sacroperineal approach (Group S) or laparoscopically assisted anorectoplasty (LAARP; Group L). Methods: Male patients who underwent repair of high- or intermediate-type ARMs at our center and aged ≥15 years as of November 2020 were enrolled. Patients with intellectual disabilities or chromosomal disorders were excluded. Sacroperineal anorectoplasty has long been routinely performed at our hospital, and LAARP was introduced as a standard procedure in 2000. The medical records of the outpatient clinic were retrospectively reviewed, and questionnaires were sent in November 2020. Data regarding erectile dysfunction, ejaculatory anomalies, and associated anomalies were collected and compared between the two groups. Results: Answers were obtained from 7/22 patients in Group S (32%) and 10/17 patients in Group L (59%). Patient characteristics were similar, but the median age at the time of replying was significantly different (22 [18-29] years in Group S and 19 [15-20] years in Group L, P = .0060). None of the patients had erectile dysfunction, but 3 patients in Group S (43%) and 5 patients in Group L (50%) had ejaculatory failure, with no significant difference between the two groups. Conclusions: The incidence of sexual dysfunction in male patients with ARM might be higher than that in the healthy population. Patients might abscond from their follow-up visits as they age; therefore, providing patients with accurate information on this issue before puberty is essential.

Laparoscopically assisted anorectoplasty-Surgical procedures and outcomes: A literature review.

Anorectal malformation includes various types of anomalies. The goal of definitive surgery is achievement of fecal continence. Twenty years have passed since laparoscopically assisted anorectoplasty (LAARP) was reported by Georgeson. Since LAARP is gaining popularity, its long-term outcomes should be evaluated. Presently, there is no evidence regarding the optimal method of ligating and dividing the fistula correctly and creating the pull-through canal accurately. Rectal prolapse and remnant of the original fistula (ROOF) tend to develop more often in LAARP patients than in posterior sagittal anorectoplasty (PSARP) patients; however, robust evidence is not available. Prolapse may be prevented by suture fixation of the rectum to the presacral fascia; however, if prolapse occurs, the indication, timing, and the best method for surgical correction remain unclear. Most patients with ROOF are asymptomatic, and there is controversy regarding the indications for ROOF resection. This article aimed to detail the various modifications of the LAARP procedures reported previously and to describe the surgical outcomes, particularly focusing on rectal prolapse, ROOF, and fecal continence, by reviewing the literature. Functional outcomes after LAARP were almost similar to those noted after PSARP, and we have demonstrated that LAARP is not inferior to PSARP with respect to fecal continence. Although there is controversy regarding the application of LAARP for recto-bulbar cases, we believe that LAARP is still evolving, and we can achieve better outcomes by improving the procedure.

Rectal Prolapse After Laparoscopically Assisted Anorectoplasty for Anorectal Malformations.

Aim: To clarify the characteristics of patients with rectal prolapse after laparoscopically assisted anorectoplasty (LAARP), estimate the causes, and evaluate its impact on postoperative bowel function. Methods: The medical records of patients who underwent LAARP for high- or intermediate-type anorectal malformation between 2000 and 2019 were retrospectively reviewed. Clinical data were compared between patients with (Group P) and without prolapse (normal, Group N). Fecal continence was evaluated using the clinical assessment score for fecal continence developed by the Japanese Study Group of Anorectal Anomalies. For patients who underwent pelvic magnetic resonance imaging (MRI) before LAARP, atrophy, or asymmetry of the anal sphincter and levator ani was evaluated by a radiologist. Results: Of the 49 patients, 29 (59%) had rectal prolapse after LAARP (Group P) and 20 did not (Group N). We found no significant difference in gender, type of malformations, incidence of associated spinal or lumbosacral anomalies, procedure time, and postoperative bowel function at ages 4, 8, 12, and 16 years. However, LAARP was performed significantly earlier in Group N (median [range], 180 [123-498] days) than in Group P (210 [141-570] days). In Group P, 18 patients (62%) developed prolapse before colostomy takedown. Eight of 26 patients who underwent surgical prolapse repair required redo procedures. Twenty-five patients who underwent preoperative pelvic MRI showed no significant relationship between the muscular abnormalities and the incidence of postoperative rectal prolapse. Conclusions: Although recurrence is common, performing LAARP at a younger age might prevent postoperative prolapse development.
