A comparative study to evaluate abdominal wall dynamics in patients with incisional hernia compared to healthy controls

BACKGROUND

Incisional hernia is a common complication following abdominal surgery. It causes change in function of core abdominal muscles leading to change in abdominal wall dynamics. This study aims to objectively measure and compare preoperative abdominal wall dynamics with surface electromyography (sEMG) in incisional hernia patients with healthy individuals.

MATERIALS AND METHODS

In this prospective comparative study, two groups of participants as cases and controls were evaluated for their abdominal wall dynamics by using sEMG. Both cases and controls were evenly matched in terms of age and gender. Statistical analysis was done with STATA 14.1 and p value of < 0.05 was considered significant.

RESULTS

Demographic profile was comparable between the two groups. Mean BMI of cases was higher than controls. The most common index procedure was lower segment cesarean section. The strength and power of all three abdominal wall muscles (rectus abdominis, external oblique, internal oblique) were significantly diminished among cases compared to controls.

CONCLUSIONS

Abdominal wall dynamics can be objectively and correctly interpreted from sEMG of abdominal wall core muscles in patients with incisional hernia. This study shows that there is a decrease in abdominal wall strength and power in patients suffering from incisional hernia in comparison with healthy controls.

Endoscopic totally extraperitoneal repair for groin hernia: Experience from a tertiary care centre

Background

Totally extra-peritoneal (TEP) and transabdominal preperitoneal (TAPP) repair are two established minimal access techniques of groin hernia surgery. TEP offers the advantage of avoiding violation of the peritoneal cavity.

Aim

This study aims to describe the decade-long experience of TEP in groin hernia repair in a tertiary care teaching institute and the feasibility of the same in difficult scenarios.

Materials and Methods

Retrospective analysis of the database of patients undergoing TEP repair for inguinal hernia in a single surgical unit at a tertiary teaching hospital between January 2008 and December 2019 was performed. Detailed pre-operative clinical details, operative duration, intraoperative and post-operative complications, including pain, length of post-operative hospital stay and hernia recurrence data were analysed.

Results

Over 12 years' duration, 511 patients underwent endoscopic TEP mesh repair and the total number of hernias repaired was 614. Majority (97.45%) of patients were male. The mean age of the patient population was 51.3 years. Primary hernia was seen in 490 patients. The mean operating time for unilateral inguinal hernia repair was 56.8 ± 16 min and for bilateral repair 80.9 ± 25.2 min. TEP in previous lower abdominal/suprapubic surgical scars was attempted in 17 (3.3%) patients, with only one requiring conversion. The intraoperative peritoneal breach was the most common documented complication (34.8%). Seroma was seen in 9.4% of patients. Seventeen patients required conversion (14 TAPP and 3 open). Recurrence was seen in 4 (0.7) patients.

Conclusion

TEP repair is an effective method of groin hernia repair and can be attempted in the majority of patients groin hernia, including patients with previous lower abdominal incisions.

Smartphone applications (apps) in general surgical practice: An insight into their reliability and usefulness

Objective: In today’s day and age with the advent of smartphones along with the handy apps available for download, there is increasing opportunities for surgeons to integrate such technology into clinical practice with great ease. This study aims to provide a systematic classification of apps in order to provide dependable data for choosing the right app by both surgeons and trainees.

Material and Methods: A series of methodical searches were carried out on “Google Play Store” and “Apple’s App Store” with pre-decided keywords. The results were then sorted and segregated into relevant categories like core surgery, apps related to surgical practice, patient utility apps and other surgical branches. Thereafter, the apps that met with our cut-offs, were assessed for their credibility and utility, based on predefined parameters.

Results: There were a lot of variations in between the categories we segregated the apps into. Using predefined cutoff criteria, (rating >3 and reviews >30), 48 of the apps were assessed finally for their utility and credibility. Out of these 48 apps, 42 were on android platform while the remaining 6 were on iOS. Ten apps were found to be having high credibility and 15 apps have high utility.

Conclusion: The role of smartphone apps in surgery and surgical training appears highly promising and using apps with high credibility and utility will provide dependable and updated information for the surgeons and trainees.

A randomized trial analyzing the effects of primary versus delayed primary closure of incision on wound healing in patients with hollow viscus perforation

Objectives

Delayed primary closure (DPC) of the skin has been suggested to decrease superficial surgical site infection (SSSI) in patients undergoing surgery for peritonitis secondary to hollow viscus perforation, but there is no consensus. The aim of this study was to compare the outcomes of primary closure (PC) and DPC of the skin in terms of SSSI, fascial dehiscence and length of hospital stay (LOS).

Material and Methods

Sixty patients, undergoing emergency surgery for perforation peritonitis, were randomized to PC (n= 30) and DPC (n= 30). Patients in the DPC group underwent skin closure four or more days after surgery when the wound was clinically considered appropriate for closure. Patients in the PC group had skin closure at the time of surgery.

Results

Incidence of SSSI was significantly less in the DPC group (7.4%) compared to the PC (42.9%) (p= 0.004). However, the median time of DPC was the 10th POD, i.e., these wounds required considerable time to become clinically suitable for closure. Incidence of fascial dehiscence was comparable between the two groups (p= 0.67). Length of hospital stay (LOS) was 13.8 days in the DPC group compared to 13.5 days in PC; the difference was not significant (p= 0.825).

Conclusion

DPC of the skin incision resulted in the reduction of SSSI. However, this did not translate into a reduction in hospital stay, as it took considerable time for these wounds to become appropriate for DPC, thus bringing into question any real advantage of DPC over PC.

Incidental Carcinoma Gallbladder: Incidence, Risk Factors, and Factors Affecting Survival-5-Year Experience from a Tertiary Care Institute

INTRODUCTION

Carcinoma gallbladder is a very lethal disease. It can get detected incidentally after laparoscopic cholecystectomy. The overall outcome of incidentally detected carcinoma gallbladder is a matter of debate in literature.

AIM

To estimate the overall incidence of the incidental gallbladder carcinoma, the various risk factors associated with it and factors affecting overall survival in patients who underwent laparoscopic cholecystectomy with eventual histology turning out to be carcinoma gallbladder.

METHODS

Data of all the patients undergoing laparoscopic cholecystectomies in one surgical unit under the Department of Surgery at All India Institute of Medical Sciences, New Delhi, India, between January 2014 and December 2018 was retrospectively analyzed. All patients with incidental carcinoma gallbladder were followed up and completion radical cholecystectomy was performed. The demographic profile, preoperative imaging, intra-operative finding, histopathology of primary surgery, and median interval between two surgeries were analyzed to look for various risk factors associated with incidental carcinoma gallbladder and factors affecting overall survival.

RESULTS

Incidence of the incidental carcinoma gallbladder was 0.51% with a female/male ratio of 4:1 and mean age of 47.2 years. Preoperative imaging of most of them was suggestive of chronic cholecystitis; however, one patient had multiple gallbladder polyps. Six patients had uneventful laparoscopic cholecystectomy, while four had bile spillages intraoperatively. All the patients had adenocarcinoma on histopathology. Pathological staging of four patients was pT1b and six patients had pT2 tumor. The median interval between cholecystectomy and completion radical cholecystectomy in this series was 8 weeks. At the end of 19-month median follow-up, overall survival was 55.5%.

CONCLUSION

Incidence of incidental carcinoma gallbladder is 0.51%, most commonly affecting middle-aged females. Risk factors associated with incidental carcinoma gallbladder were found to be multiple gallbladder calculi, single large stone, and gallbladder polyps. Survival is better in males, young patients with uneventful primary surgery and better-differentiated pathology.

Lipoleiomyosarcoma of spermatic cord: an unusual presentation

Spermatic cord malignancies are very rare tumours. Less than 100 cases of cord liposarcoma have been reported in the literature. Divergent differentiation into leiomyosarcoma and liposarcoma is a rare phenomenon but can occur. Lipoleiomyosarcoma usually represents the well-differentiated subtype of this entity. We report such a rare case in spermatic cord with an unusual presentation as a recurrent inguinal hernia in a 62-year-old man.
