Developments in Hand Surgery: Experience from a Tertiary Hospital of Northern Bangladesh.

Hand Surgery is a specialized branch of Plastic and Reconstructive surgery. There are many conditions that require hand surgery, for example, congenital deformity, electric or flame burn, mechanical or road traffic injury, and post burn or post traumatic deformity. A retrospective observational study was conducted in the department of Burn and Plastic surgery, Mymensingh Medical College Hospital, Bangladesh during a 2 years period extending from 9th September 2021 to 8th September 2023. The objective of this study was to see the hand surgery status in a tertiary hospital of Bangladesh during the post Covid pandemic period. During this period 236 hand surgery procedures were performed in 176 patients. The age of the patients ranged from 02 to 78 years (Mean 31.14±1.52). One hundred and four (59.0%) were male and 72(41.0%) were female. Thirty-four (19.32%) patients had co-morbidities e.g., Epilepsy, Diabetes Mellitus, Chronic Kidney Diseases and HBsAg +ve. Causes of surgery included, wound due to electric burn 49(27.84%), flame burn 36(20.45%), post traumatic 24(13.64%), post infective 11(06.25%), tumor excision 02(2.24%), Dupuytren's contracture 03(1.70%), congenital anomalies 06(3.41%), post burn scar contractures 41(23.29%), nerve injury 01(00.57%) and carpal tunnel syndrome 01 (00.57%). Procedures were performed: post burn scar contracture release 41(17.37%), syndactly release 06(2.54%), release of post traumatic contracture 06(2.54%), carpal tunnel release 01(00.42%), release of Dupuytren's contracture 03(01.27%), nerve repair 01(00.42%), debridement, amputation and Fillet flap 29(12.29%), split thickness skin graft 46 (19.49%), V-Y advancement flap 06(2.54%), transposition flap 18(07.63%), cross finger flap 16 (06.78%), reverse cross finger flap 02 (00.85%), first dorsal metacarpal artery (FDMA) flap 05 (02.12%), reverse FDMA flap 01 (00.42%), metacarpal artery perforator flap 08(3.39%), radial artery perforator flap 04(01.69%), posterior interosseous artery flap 05(2.12%), abdominal flap 11(04.46%) and flap division and insetting 27(11.44%). Outcome of surgery was satisfactory in 225(95.34%) and 11(04.46%) cases had complications (p value 0.453), which was not significant. So, it can be concluded that the outcome of various types of hand surgery procedures in tertiary hospital of northern Bangladesh during the post Covid period was satisfactory overall.

Coverage of defects over Posterior aspect of Ankle Joint and Heel with Lateral Calcaneal Artery Flap- Experience in Mymensingh Medical College Hospital.

Lateral calcaneal artery flap is randomly used by many Plastic Surgeons for covering any defect on the posterior aspect of heel. A prospective observational study was conducted in the Department of Burn and Plastic Surgery, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2020 to June 2022, to see the outcome of the flap for coverage of defects over the posterior aspect of ankle joint and heel. A total number of 09 patients, selected by purposive sampling, were included in the study. The age of the patients ranged from 06 years to 70 years. The cause of the defects were post traumatic in 07 cases, electric burn in 01 case and pressure sore in 01 case. The defect sizes varied from 3×2 to 6×3cm. and flap size ranged from 4×2.5 to 7×4.5cm. The follow-up period ranged from 3 to 6 months. All the flaps survived completely without any complications; except in two cases. In one case, there was marginal epidermal necrolysis that healed secondarily without the need of any further surgical intervention. In the other case, there was gangrene of about 0.5 cm area at the flap tip, which was debrided and the resulting wound healed secondarily. The average operating time was 63 minutes. The results were satisfactory on the context of adequate coverage, and flap and donor site morbidity. So, the lateral calcaneal artery flap can be a good and safe option for the coverage of posterior ankle and heel defects.

A Comparative Study of Collagen Sheet versus 1% Silver Sulfadiazine Dressing in Superficial Partial Thickness Burns.

Burn injury causes a lot of suffering. The goal of burn management is to achieve rapid wound healing, pain relief, rehabilitation with minimum scars and optimal functional ability. Objective of this study was to compare the efficacy of collagen sheets and 1% silver sulfadiazine dressing (SSD) for superficial partial thickness burns. This prospective observational study was conducted among the patients of Department of Plastic surgery, Dhaka Medical College Hospital, and Sheikh Hasina National Institute of Burn and Plastic Surgery, Dhaka, from 1st April 2020 to 31st March 2021. Total 60 patients with superficial partial thickness burns by purposive sampling 30 patients of them were treated with collagen sheet dressing (Group A) and 30 patients with 1.0% silver sulfadiazine dressing (Group B). First case was selected by tossing a coin. Then every alternate patient was provided the same kind of dressing material (either collagen sheet or 1.0% silver sulfadiazine). Data were collected by semi structured data collection sheets. Pearson's chi-square test and student's 't' test were used for data analysis (p value was significant at <0.05). It was observed that a total of 18(60.0%) patients belonged to age <10 years in Group A and 17(56.7%) patients in Group B. The mean age was 14.9±14.2 years in Group A and 11.6±10.2 years in Group B. Good quality of healing was significantly higher in the collagen group compared to the SSD group (<0.05). The mean complete healing time in the collagen group was 10.47±2.21 days and in the 1.0% SSD group were 13.07±2.33 days. The mean healing time was significantly lower in the collagen group compared to the 1.0% SSD group (p<0.001). There was no significant difference in infection rate between the two groups (p>0.05). Considering the overall outcome, Collagen sheet dressing decreases pain, reduces the need for analgesics, aids in early healing as compared to the patients treated with 1% silver sulfadiazine.

Outcome of Operative Management of Lumbar Spinal Canal Stenosis at Mymensingh Medical College & Hospital.

Variety of conditions may be responsible for low back pain but lumber spinal canal stenosis is an important cause of low back pain. Lumber spinal canal stenosis usually presents with low backache with neurogenic claudication and shortness of walking distance in adult patient. Surgical management of lumbar spinal canal stenosis by decompression surgery is effective method. This prospective interventional study was performed in patient with clinical features like low back pain with radicular pain, neurogenic claudication, signs of root compression, positive MRI findings attending in department of Orthopaedic Surgery Mymensingh Medical College Hospital and Private Hospital from July 2016 to June 2019. Thirty patients were evaluated among those 20(66.6%) were 50 years and above. The mean age was 47.5±1.6 years. Male to female ratio was roughly 8:1. Almost all of the patients had low backache with radiation to the back of the thigh and leg with motor weakness (60%). About 66.6% of the patients had sensory deficit and 83.3% had neurogenic claudication. Majority (80.0%) of the patients at presentation had a suffering of 12 or >12 months. The mean duration of suffering was 14.7±5.1 months. About 55% of the patients were able to perform heel-walking and 36.0% tip-toe walking. Nearly 57% of the patients had sensory deficit along the distribution of 1st sacral nerve and 53.3% along the distribution of lumber 5 nerves. Diagnosis shows that 16.6% of patients had L4 lesion, 50% L5, 10.0% patients had L4 & L5 and 46.6% S1. Laminectomy was done in 26.6% of patients, laminectomy and disectomy in 33.3% and laminectomy, discectomy & foraminal decompression in 40.0% of patients. Twenty five (83.5%) of patients was free from symptoms. Eighty percent (80.0%) of patients shows minimal disability and 20.0% moderate disability on the basis of Oswestry Disability Index, while by MacNab criteria, most (80%) of patients was excellent, 10% good and another 10% fair. Repeated measure ANOVA statistics showed that mean Oswestry score decreased significantly from 54.5% at baseline to 22% at the end of 1 year (p<0.001).

Crane Principle in Plastic Surgery- Experience in Mymensingh Medical College Hospital.

The crane principle is a Plastic surgical technique whereby, a pedicled flap can be used as an engineering crane to lift and transport subcutaneous tissue from one area and deposit it in another. The flap can be returned later to its original bed. It takes only one week for the conveyance. Here we present a case of 25 year old female patient with degloving injury of scalp with exposed skull bone was initially managed with transposition flap for coverage of the scalp defect in Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh on 07 December 2017. After 8 months the scalp flap was returned to its original site following the crane principle and the new wound was covered by split-thickness skin graft. The flap survived completely and patient was satisfied.

Posterior Tibial Artery Perforator Based Propeller Flap for Lower Leg and Ankle Defect Coverage: A Prospective Observational Study.

Reconstruction of lower leg and ankle defect with exposed bone or tendon is a challenging task for a Plastic Surgeon. There are various options, among them perforator based propeller flap is a very good option though this is a microsurgical procedure but no need of microvascular anastomosis. This study was designed to see the clinical results of Posterior tibial artery perforator based propeller flap for lower leg and ankle defect coverage. The study was a prospective observational study. It was conducted in the Department of Burn and Plastic Surgery, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2017 to June 2018. Sample size was 9. Sampling was carried out purposively. Postoperative follow up period was up to 6 weeks. Among the 9 cases, 8 flaps completely survived, 1 case developed marginal necrosis which was secondarily healed. There were total 2 complications among 9 cases i.e. transient venous congestion and superficial epidermonecrolysis which were resolved spontaneously. Regarding the cause of the defect, maximum cases were post traumatic wound (66.7%), others were post infective, post malignancy excision and post electric burn wound. Defect size was 2cm×2cm to 7cm×5cm. Maximum dimension of the flap was 19cm×6cm and minimum size was 7cm×3cm. Posterior tibial artery perforator location was 4cm to 9cm from lowest level of medial malleolous (mean 6.2±1.6cm). Rotation of the flap was 145°-180° (mean 163°±1.39°). In all cases donor site was covered with split thickness skin graft. Operation time was 120 minutes to 180 minutes; mean operative time was 143.3±2.38 minutes. After operation hospital stay was 10 days to 21 days, mean 11.44±3.64 days. So, posterior tibial artery perforator based propeller flap for lower leg and ankle defect coverage is a very good option.

Fetomaternal Outcome in Eclampsia in Relationship with Gravidity.

Eclampsia is a well-recognized major cause of maternal and perinatal morbidity and mortality. Patient's age, occupational status, socioeconomic status, educational status, regular ANC (antenatal care) and gravidity may affect the outcome of mother and foetus. The purpose of this study is to see the fetomaternal outcome in eclampsia in relationship with gravidity. This prospective observational cross-sectional study carried out among the alternate cases of primigravid and multigravid eclamptic patients. Total number of patients was 100 eclamptic patients among them, 50 patients were primigravida and 50 patients were multigravida. The study was conducted in Eclampsia unit of Department of Gynaecology and Obstetrics, Dhaka Medical College Hospital, Dhaka, Bangladesh from 21 November 2011 to 20 May 2012. In this study, it was observed that ARF (acute renal failure) occurred in 6%, of these 4 cases of multigravida and 2 cases of primigravida. Cerebro vascular accident (CVA) was reported in 16 patients and 26% in multigravida and 6% in primigravid patients. HELLP (Haemolysis, Elevated liver enzymes and low platelets) syndrome developed in 25 cases of multigravida and 6 cases of primigravida. Heart failure occurred in 7% cases, out of these 6 cases were multigravida and 1 case was primigravida. Pulmonary edema was observed in 41%, among were 21 cases of multigravida and 20 cases of primigravida. Incidence of DIC (disseminated intravascular coagulation) was noted in 2 cases of multigravida and 1 case of primigravida. PPH (postpartum haemorrhage) occurred in 10 cases of multigravida and 3 cases of primigravid patients. Puerperal psychosis was reported in 8% of multigravida and 4% of primigravida. Total 4% of patients expired, among them 3 cases were multigravida and 1 case was primigravida. Perinatal mortality was 21 cases in multigravida and 8 cases in primigravida. The incidence of live birth, in case of multigravida was 39 cases and primigravida 45 cases. Data were analyzed by paired student's 't' test. There was no statistically significant difference between primi and multigravida in feto-maternal outcome. This study reveals that gravidity does not alter the feto-maternal outcome in eclampsia.
