Delayed wound healing particularly in difficult wounds and in elderly with co morbidities is a major concern. It leads to the pain, morbidity, prolonged treatment, and require major reconstructive surgery which imposes enormous social and financial burden. Vacuum-assisted closure (VAC) is an alternative method of wound management, which uses the negative pressure to prepare the wound for spontaneous healing or by lesser reconstructive options. Method of VAC application includes thorough debridement, adequate haemostasis and application of sterile foams dressing. A fenestrated tube is embedded in the foam and wound is sealed with adhesive tape to make it air tight. The fenestrate tube is connected to a vacuum pump with fluid collection container. The machine delivers continuous or intermittent suction, ranging from 50 to 125 mmHg. The VAC dressings are changed on 3rd day. Negative pressure therapy stabilizes the wound environment, reduces wound edema/bacterial load, improves tissue perfusion, and stimulates granulation tissue and angiogenesis. All this improves the possibility of primary closure of wounds and reduce the need for plastic procedures. VAC therapy appears to be a simple and more effective than conventional dressings for the management of difficult wound in terms of reduction in wound volume, depth, treatment duration and cost.

Background:Awareness of anatomical variations of the median nerve at wrist is important in repair of traumatic injuries and treatments of compression syndrome because in these situations precise dissection of the nerve is mandatory and such variations are not infrequent.Materials and Methods:In this study, 52 hands of 52 fresh cadavers were dissected and median nerve anatomy along with the presence of persistent median artery (PMA) was noted.Results:A total of 26 hands (50%) had the deviation from the standard text book anatomy of the median nerve. There was early division of the median nerve into the medial and lateral branches in 11.53% hands. There was early branching of the 2nd common digital nerve in 9.6% hands. The transligamentous motor branch to the thenar muscle was most prevalent (42.3% hands). The single motor branch to the thenar muscles was found in the majority of hands (84.6%). The PMA was present in 11.53% hands and it was associated with variations in the median nerve anatomy in all cases.Conclusions:This study shows a high percentage of deviation from standard anatomy as well as a high percentage of transligamentous thenar muscle motor branch. The presence of PMA was associated with variations in the median nerve anatomy in all cases. Therefore if PMA is present there are very high chances of associated median nerve anomalies.

BackgroundGlobal surgery has recently gained prominence as an academic discipline within global health. Authorship inequity has been a consistent feature of global health publications, with over-representation of authors from high-income countries (HICs), and disenfranchisement of researchers from low-income and middle-income countries (LMICs). In this study, we investigated authorship demographics within recently published global surgery literature.MethodsWe performed a systematic analysis of author characteristics, including gender, seniority and institutional affiliation, for global surgery studies published between 2016 and 2020 and indexed in the PubMed database. We compared the distribution of author gender and seniority across studies related to different topics; between authors affiliated with HICs and LMICs; and across studies with different authorship networks.Results1240 articles were included for analysis. Most authors were male (60%), affiliated only with HICs (51%) and of high seniority (55% were fully qualified specialist or generalist clinicians, Principal Investigators, or in senior leadership or management roles). The proportion of male authors increased with increasing seniority for last and middle authors. Studies related to Obstetrics and Gynaecology had similar numbers of male and female authors, whereas there were more male authors in studies related to surgery (69% male) and Anaesthesia and Critical care (65% male). Compared with HIC authors, LMIC authors had a lower proportion of female authors at every seniority grade. This gender gap among LMIC middle authors was reduced in studies where all authors were affiliated only with LMICs.ConclusionAuthorship disparities are evident within global surgery academia. Remedial actions to address the lack of authorship opportunities for LMIC authors and female authors are required.

The use of polypropylene mesh for contaminated and dirty strangulated hernias is effective and safe, with acceptable morbidity and good short-term results.

Peptic perforation is a serious complication of peptic ulcer disease. The defect in the intestinal wall usually does not present a difficult technical problem of surgical management, in most cases perforation can be closed primarily. On rare occasions an extremely large defect (giant peptic perforation – defined as any perforation greater than 2.5 cm in size) cannot be closed by these simple techniques. Modalities of treatment advocated for such an ulcer over the years are: free omental plug in the form of a mushroom; serosal patch technique; jejunal pedicle graft, partial gastrectomy, and finally the possible addition of proximal gastrojejunostomy. The omental plug is a simple procedure which does not require expertise and can even be performed in a very short time by a trainee general surgeon in a seriously ill patient in emergency. We review 7 cases of giant peptic perforations closed by a free omental plug.
