Ligation of Processus Vaginalis During Orchidopexy: Is It Mandatory?

Introduction: Undescended testis is one of the commonest presentations in pediatric population. Conventionally, high ligation of the hernia sac was done after vas and vessels were dissected in order to prevent post-operative hernia. However, recent studies have shown that hernia sac ligation was unnecessary. Aims: To evaluate the role of hernia sac ligation during orchidopexy to prevent the development of postoperative hernia and to compare the mean operative time with and without sac ligation. Methods: A prospective comparative study was conducted with a total of 94 patients with undescended testis, age ranging from six months to 16 years were included in the study from November 2018 to May 2021. Cases were randomly divided into two groups. In Group A cases, orchidopexy was carried out with sac ligation, while in Group B, the hernia sac was not ligated. Mean operative time was recorded in each case. All the patients were followed up at one, four and eight weeks post-operatively and examined for postoperative hernia. Results: Of the total 94 cases, there were 18 bilateral and 76 unilateral cases of which 56 were right-sided and 22 left-sided. Most of the patients (45) of the study were between six months and 2 years. None of the patients of either group developed post-operative hernia or any significant complications. The mean operative time for group A and B were 36.72 and 46.96 minutes respectively. Conclusion: It was concluded that ligation of processus vaginalis was unnecessary during orchidopexy and sac ligation consumed more operative time.

Analysis on Influencing Factors of Recurrence after Indirect Inguinal Hernia Laparoscopic Surgery

This paper aims to analyze the recurrence of indirect inguinal hernia in children after laparoscopic surgery and investigate the influencing factors that may lead to recurrence so as to guide the prevention and treatment of postoperative recurrence of this kind of disease in the future. The data of 260 children with indirect inguinal hernia treated by laparoscopic surgery and followed up in our hospital from July 2019 to July 2021 were selected. A self-designed questionnaire was used to collect the basic data. The recurrence was analyzed, and the influencing factors of recurrence were analyzed by univariate analysis and multivariate analysis. Among 400 children after indirect inguinal hernia laparoscopic surgery, an occurrence was observed in 15 children, and the recurrence rate was 5.77%. Univariate analysis showed that the age and course of disease were not correlated with recurrence after indirect inguinal hernia laparoscopic surgery ( P > 0.05 ). Being male, bilateral lesions, exact high ligation, loose hernia back wall peritoneum, deciduous ligature, incorrect ligation of the fascia of musculus obliquus externus abdominis, large inguinal hernia, circumferential wiring, and too early off-bed activity were the influencing factors of recurrence after indirect inguinal hernia laparoscopic surgery ( P < 0.05 ). Logistic multivariate regression analysis showed that being male, bilateral lesions, loose hernia back wall peritoneum, deciduous ligature, incorrect ligation of the fascia of musculus obliquus externus abdominis, large inguinal hernia, and too early off-bed activity were the influencing factors of recurrence after indirect inguinal hernia laparoscopic surgery (OR>1, P < 0.05 ). Exact high ligation and circumferential wiring were protective factors of recurrence after indirect inguinal hernia laparoscopic surgery (OR>1, P < 0.05 ). After indirect inguinal hernia laparoscopic surgery, recurrences were affected by many factors, such as gender, site of pathological changes, and loose hernia back wall peritoneum. For these children with risk factors, reasonable intervention should be taken to reduce recurrence; exact high ligation and circumferential wiring are the protective factors. If permitted, the children meeting related indications can be treated by high ligation or circumferential wiring to reduce the risk of recurrence after indirect inguinal hernia laparoscopic surgery.

High Ligation of the Inferior Mesenteric Artery Induces Hypoperfusion of the Sigmoid Colon Stump During Anterior Resection

Background: Anastomotic leakage (AL) after colorectal surgery is associated with insufficient vascular perfusion of the anastomotic ends. This study aimed to evaluate the effect of high vs. low ligation of the ileocolic artery and inferior mesenteric artery, respectively, on the vascular perfusion of the bowel stumps during ileocecal resection (ICR) and anterior rectal resection (AR).Methods: We retrospectively evaluated patients who underwent ICR or AR between 2016 and 2020. Real-time indocyanine green fluorescence angiography was performed to measure the fluorescence time (FT) as a marker of the blood flow in the proximal and distal stumps before anastomosis.Results: Thirty-four patients with lower right-sided colon cancer underwent laparoscopic ICR. Forty-one patients with rectosigmoid colon or rectal cancer underwent robotic high AR (HAR) (n = 8), robotic low AR (LAR) (n = 6), laparoscopic HAR (n = 8), or laparoscopic LAR (n = 19). The FT was similar in the ileal and ascending colon stumps (p = 1.000) and did not differ significantly between high vs. low ligation of the ileocolic artery (p = 0.934). The FT was similar in the sigmoid colon and rectal stumps (p = 0.642), but high inferior mesenteric artery ligation significantly prolonged FT in the sigmoid colon during AR compared with low ligation (p = 0.004), indicating that the high ligation approach caused significant hypoperfusion compared with low ligation. The AL rate was similar after low vs. high ligation.Conclusions: Low vascular perfusion of the bowel stumps may not be an absolute risk factor for AL. High inferior mesenteric artery ligation could induce sigmoid colon stump hypoperfusion during anterior rectal resection.

Low Ligation Plus High Dissection Versus High Ligation of the Inferior Mesenteric Artery in Sigmoid Colon and Rectal Cancer Surgery: A Meta-Analysis

BackgroundWhether high or low ligation of the inferior mesenteric artery (IMA) is superior in surgery for rectal and sigmoid colon cancers remains controversial. Although several meta-analyses have been conducted, the level of lymph node clearance was poorly defined. We performed a meta-analysis comparing high and low ligation of the IMA for sigmoid colon and rectal cancers, with emphasis on high dissection of the lymph node at the IMA root in all the included studies.MethodsPubMed, MEDLINE, and EMBASE databases were searched to identify relevant articles published until 2020. The patient’s perioperative and oncologic outcomes were analyzed. Statistical analysis was performed using the statistical software RevMan version 5.4.ResultsA total of 17 studies, including four randomized controlled trials, published between 2011 and 2020 were selected. In total, 1,846 patients received low ligation of the IMA plus high dissection of lymph nodes (LL+HD), and 2,648 patients received high ligation of the IMA (HL). LL+HD was associated with low incidence of anastomotic leakage (p &lt; 0.001), borderline long operative time (p = 0.06), and less yields of total lymph nodes (p = 0.03) but equivalent IMA root lymph nodes (p = 0.07); moreover, LL+HD exhibited non-inferior long-term oncological outcomes.ConclusionIn comparison with HL, LL+HD was an effective and safe oncological procedure for sigmoid colon and rectal cancers. Therefore, to ligate the IMA below the level of the left colic artery with D3 high dissection for sigmoid colon and rectal cancers might be suggested once the surgeons are familiar with this technique.Systematic Review RegistrationINPLASY.com, identifier 202190029.

Efficacy Comparison and Safety Analysis of Radical Resection of Sigmoid Colon Cancer Based on Different Cancer Locations

Background: Sigmoid colon cancer is a common type of colon cancer; it refers to tumor lesions occurring in the segment approximately 16 cm to 50 cm from the anal margin. Currently, surgical resection is the most effective treatment for non-metastatic sigmoid colon cancer. Therefore, to more accurately standardize colon cancer surgery, we classified the sigmoid colon into distal and proximal segments. This study compares and analyzes the intraoperative situation, postoperative pathology and safety of radical resection of sigmoid cancer in different locations from different aspects. Result: The patients with sigmoid colon tumor can be divided into distal group (16-30cm from the anus) and proximal group (31-50cm from the anus) according to the distance between the tumor and the anal margin. Conclusion: The patients in the distal group using stapler for intestinal anastomosis and anal decompression tube were significantly more than those in the proximal group. For the ligation of the inferior mesenteric artery, high ligation was usually used or the left colic artery was usually preserved in the distal group, and the superior rectal artery was usually retained in the proximal group. The incidence of postoperative complications in the distal group was higher than that in the proximal group, but there was no significant difference between the two groups.

Single-port Laparoscopy with Modified Needle Hook-assisted Extracorporeal High Ligation of Hernia Defects (Suwardi’s Technique): An Experience from Single-center Hospital

BACKGROUND: Laparoscopy has long been used for the evaluation of hernia defects on the contralateral side when performing herniated tears in children. In 1997, El Gohary first reported laparoscopic treatment of hernia repair in a female patient. Since then, laparoscopic inguinal hernia ligation has been performed in various medical institutions with a variety of methods including closing the defect intraperitoneally and extracorporeal ligation of the herniated ring defect. CASE PRESENTATION: Data were taken from January 2016 to December 2020 in the Pediatric Surgery Department of Dr. Moewardi General Hospital, Surakarta. A total of 22 cases, consisting of 19 boys and 3 girls aged 1–14 years (mean 5 years), underwent single-port laparoscopy with modified extracorporeal ligation of hernial defects using an epidural needle. From the results of surgery from January 2016 to December 2020, there were 22 patients with a follow-up period of 6 months who were carried out with a single port without the assistance of forceps and hydrodissection with a single-port laparoscopic technique that had been modified extracorporeally using an epidural needle and were able to evaluate the contralateral side. Thus, it shortened the operating period and the patient was able to be discharged 24 h postoperatively without any complications. CONCLUSION: From 22 patients who used single-port technique with modified extracorporeal ligation of hernia defects using epidural needles, the results were shorter operation time, without complications and satisfying cosmetic results.
